It's been 7 years since I was at Meeting C++ and I'm really looking forward to it. There are great keynotes planned and the schedule as a whole is full of talks I want to hear! I'm doing The Aging Programmer and hope it lands as well in Berlin as it has elsewhere. As always, I find it hard to believe there are too many C++ conferences for me to be at all of them, and I'm making an effort to try to mix things up from year to year and not just go to "the usual places" every time. It's good to see some speakers I haven't seen for a while, and be introduced to ideas I haven't been following.

There's still time to get your tickets! I hope to see you there.

Kate

Tomorrow I head to Norway for NDC Techtown. And now I'll be doing two talks there! I'm adding Naming is Hard to my scheduled Aging Programmer. There probably isn't time for you to register and travel there, but if you'll be there, plan to see both my talks!

Kate

We work on the conference for a year, maybe more than a year, because we start thinking about "next year" before we've even had this year. Then it starts, and it's wonderful, and suddenly it's the last day.

We kicked off the day with a wonderful keynote by April Wensel about compassion and how bringing warmth and caring into your software development practices makes better code, not just happier people. Then I went to Tina Ulbrich's Throwing Tools at Ranges which had a lot of numbers and data for those who worry ranges bring performance issues.

A CppNorth tradition is that we don't provide lunch every single day, wanting to send attendees out into Toronto to experience the downtown neighbourhood. Day 3 was the "go out" day for lunch and from what I heard in the afternoon, people liked it, as they have other years. After lunch I went to Where There Is A Loop There is an Algorithm by Peter Lorimer and Fatemeh Jafargholi. I really liked how Fatemeh connected something I said about memorable catchphrases like "better safe than sorry" to algorithms and their names.

Then another Conor Hoekstra "so many languages" talk, Composition Intuition II. It was a careening ride between "heh, I can actually follow this, that is kind of neat" and "what?!?". Conor takes some of the mystery out of jargon words you hear other people use and helps to bring concepts from esoteric languages ("this one was written for winning code golf challenges") into our regular lives.

Then came perhaps the most anticipated break of the conference: The Canadian Snacks Break!

Butter tarts, nanaimo bars, maple cookies, and little bags of Hickory Sticks! You won't forget where you are at this conference!

We wrapped up with a keynote from Tony Van Eerd that appeared for a while to have only one slide (but actually had 86) and a lot of philosophy and thinking. To do a good job of abstraction, you need to think about what a thing is, and what the properties of a thing are, and Tony led us through that very skilfully. Definitely one to chew on on the way home.

And with that I was on the way home. Into the GO station that literally connects to the Microsoft building:

And on the train, with one well-timed selfie-with-the-venue:

See you all next year! You can even buy your tickets right now for a huge discount to use this year's budget, if you like!

Kate

Day 2 at CppNorth started with Lightning Talks! But first I had to walk to the venue. When I drive around, I'm used to a flagger making cars stop from time to time to let a construction vehicle proceed. But this was my first sidewalk flagger:

The lightning talks were terrific, as they so often are. Funny, helpful, educational, often all 3. Pier-Antoine Giguère was our high-energy MC and really shone. I don't have any pictures because I was paying attention to all the talks!

Then it was Chandler Carruth, one of my fellow Carbon leads, with How Designing Carbon with C++ Interop Taught Me About C++ Variadics and Overloads, a talk I definitely enjoyed. There was plenty of code in both languages.

The audience seemed to enjoy it, too. After lunch I went to Hiding your Implementation Details is Not So Simple by Amir Kirsh, who has a gentle teaching style I really like. Then it was Mitigating the Intellectual Anxiety Associated with Learning the C++ Programming Language by Emmanuel Danso Nyarko from CppAfrica. If you've ever worried about C++'s reputation for being "the language for smart people" this talk will show you just how real it is. The reality of what jobs are available in Africa controls what languages people will learn. With no high-paying fintech or envy-of-your-friends gamedev employers, why would someone take on something they think is incredibly difficult?

This also applies to what is in the standard library. Seasoned C++ developers with lots of community folks to talk to can figure out how to build a UI. Different projects will make different choices - use Qt or some similar C++ framework, put a not-C++ frontend on a C++ engine, or some of the other choices of various age and success. But how does someone without that community navigate those choices and get started? Why doesn't the standard library help with that in any way at all other than "console apps" with keyboard input and text output?

Then I went to see Sohaila Ali, a very poised 17 year old with years of experience in hackathons and other contests and conferences, talk about career from that youth perspective. The audience was very engaged and the conversation after the talk was lively and enlightening.

Alas, as that talk wrapped up I had to do as I mentioned in my keynote and accept my own limitations. After a very full day of interesting talks I needed to cut the input for a while so I did not see Eric Wastl's keynote. I look forward to the recording, because I heard it was good.

One more day to go!

Kate

Monday morning started with a short walk to the venue. The first few minutes were against the flow of Toronto commuters pouring off a GO train and walking to nearby offices, which was quite an experience. But on reaching the 44th and 43rd floors, the reward was an amazing view!

I was worried about whether this year's food would be able to match the wonderful food we had our first two years, at a hotel. Well, it's been just as good and even better at times. Here's the morning pastries and fruit:

I had the opening keynote again this year. Here's the empty room after my tech check:

My talk went really well. This was the first time I had ever given it. I really wanted to reach the younger people, and I believe I did, to make sure they are aware there are things they can do early on to build up resources that will help you have a happy and healthy old age, and program for as long as you want to. I'll blog a link to the recording when it's live. Here's a picture from Twitter:

After my talk, I attended "C++ is a MetaCompiler" by Daniel NikPayuk. He had terrific outlining on his slides.

I urge everyone who is doing a talk to bake all their highlighting and "notice here that" into the slides themselves. Show the code, then advance or build or whatever you call it in your slide tech, so that the thing you want to show people is highlighted in some way. A coloured background like this works fine. Talk to it, then advance to the next thing. This is quicker than anything you might do with a mouse or other tool on the fly, it looks neater, it is guaranteed to be on the recording (pointing with your hand or a laser pointer never is), and the slides themselves remind you of the things you wanted to point out on them! I learned a lot from Daniel this week, starting in this talk but not ending there.

Then I watched Beginner's Mind, Expert's Mind by Dawid Zalewski. This talk was literally about minds in a way I wasn't expecting and it was very good. Highly recommended.

After lunch (spent mostly goggling at the amazing views, but the food continued to be very good) I went to "Software Engineering Completeness : Knowing when you are done and why it matters" by Peter Muldoon and "Meandering Through C++ to Create ranges::to" by Rud Merriam. I really enjoyed both of these, one for having no code at all but understanding how code fits into the big picture, and the other for having a lot of code and opinions about that code.

Then I went back to the hotel for a nap so that I could attend the Belonging Dinner in the evening. Negar Farjadnia talked about living as your authentic self and how even if there are a lot of barriers to that, putting in the effort to overcome those barriers and reach a place where you can live authentically brings huge rewards, not just in being happier but in many other aspects of your life.

What a first day! Super pleased with how it went!

Kate

Sunday I travelled to CppNorth in Toronto. It started for me with a bus trip:

After the bus, I had an hour on the train and then a 5 minute walk to the conference hotel, the Royal York. I waited for my room to be ready and was pleased to be able to see the venue from the hotel:

It's the blue glass building with the diamond shapes on the side. Going back and forth between the venue and the hotel is quick and easy.

That evening we had a small reception to pick up our badges. I liked these pronoun pins:

I also enjoyed the Northern Lights image on the badges. I met people who were here in previous years, new speakers, and old friends I am happy to see many times a year. Everyone was eager and ready to learn. It's a great start to the week for sure!

Kate

I really enjoy speaking at NDC Techtown in Norway. The airport is pleasant and easy to navigate, the trains are reliable, and it's a quick walk from the train station to the hotel, which is right at the venue. Plus the other speakers are always amazing, so I have a jam-packed two days of sessions to attend. Many years ago I decided to only speak at conferences where I would want to watch sessions, and it improved my life tremendously!

This year I'll do The Aging Programmer. This is a new talk that should be helpful for even the youngest programmers amongst us, because when it comes to planning for a happy old age doing what you enjoy, it's never too late, and it's also never too soon.

See you there! You've got three more days to order Early Bird tickets!

Kate

I am really starting to look forward to CppNorth. We're in a new venue this year, the Microsoft Canada offices! They have a lovely suite of presentation rooms that they make available to community groups like ours. The program is chosen, and we're working on the schedule. In the meantime you can see the speakers and their talks. If you're ready, register now! You can also book a room at the conference hotel, the Royal York. It's an easy walk from Union Station to both the conference and the hotel as you can see from this map showing all three.

For those who would fly to Toronto, there's a train called the UP between Union Station and YYZ. You should plan to come a little early so you can do some sightseeing before the conference. There's a see-and-do channel on the conference discord that will give you some great ideas.

I'm honoured to do the opening keynote again. This year's topic: The Aging Programmer. Eyes, wrists, memory, stamina ... so many things we rely on can get weaker as we age. That doesn't mean you can't keep going if you want to. I'll talk about it.

See you there!

Kate

On January 8th, 2004, I got an email from the MVP Lead for Visual C++ at Microsoft, asking if I would like to be an MVP. After checking to see what that meant, I said yes, and was accepted into the program. I was renewed every year, and at some point after half a year, making just over 20 years coming up at the end of June. I'm still the only MVP called Kate.

I went out for MVP Summit that first year, and some RD stuff at the same time. Here's a production still from "Red Chair Green Wall" - the plan had been to greenscreen in some image related to where we each were from, but then in the end, we didn't. I'm including it to show how much younger I was then!

I've decided not to renew this year. Usually, people making this announcement do so because they're no longer doing the sorts of things MVPs do. But I'm still teaching, speaking, helping folks online, writing the occasional book, helping to run a conference, and all the technical things as well. What's changed isn't so much me, it's the program. I always valued my connection to the Visual C++ team very highly. These days, the team maintains those connections with developers whether they are MVPs or not. Events like Pure Virtual C++, among other things, can keep me informed as well or better than the program can. The MVP program is all Azure this and AI that and exciting details and announcements about conferences that just aren't relevant to me. I'm sure they are useful and exciting tools and events, for someone. I am focused on my little piece of the world and don't need more information on the stuff I've decided to ignore.

Joining the program was definitely life changing. I had some wonderful times, learned things I really needed to learn in as quick and enjoyable a way as you can imagine, met terrific people and raised my professional profile. I would do it all again in a heartbeat. I'm just not going to keep doing it, because for me personally the benefits are dwindling.

I'm truly grateful to John Perry, for bringing me into the program, to Karen Young for inspiration and funny stories, to Sasha Krsmanovic for everything, to Sim Chaudhry for cheer and support, and to Betsy Weber for being the last one standing. Most of all, I'm grateful to my fellow C++ MVPs, and the Canadian MVPs from all technologies, for being great people to spend time with and learn from. There are too many to mention -- I hope you all know you really made a difference.

Sure, I could have cropped it a little tighter, but then you wouldn't see the picture in the background of me with Bill Gates :-) What a marvelous pair of decades!

Kate

During CppNorth, I took a few minutes away from the conference to do an interview for Pluralsight. The host was my dear friend Julie Lerman and we had a great time. We talked about my courses, #include <C++>, CppNorth, Carbon, and a lot more.

I thought you might like to see a few "production stills" of how I set up the space to do the recording. It's always a challenge in a hotel room to get good light, keep the bed out of frame, and be reasonably near an available power plug. I did it!

Yes, I have my ring light clipped to a lampshade. And I brought the light, my good mike, and my mike stand to Toronto with me in my suitcase. Getting the laptop up high enough and at the right angle involved a little foraging in the room :-)

This was the view from my chair. (That desktop background is the view out of the Bridge of Sighs, in Venice.)

And here's the final video.It's about seventeen minutes; please do share the link with others.

Kate

The recordings from ACCU have been appearing over the last few weeks and now both of my talks are up:

• C++ And Beyond: Discussion is a panel discussion with Vittorio Romeo, Kevlin Henney, Nico Josuttis, and me, moderated by Bryce Lelbach. The fun starts just six minutes in when Nico declares C++ "fundamentally broken." Still, there is some positive and hopeful content. We should think about the languages we use and what we want from them. C++ is a language that changes, which has consequences, both good and bad.
• Become a Better Programmer by Using Words and Ideas From Casual Gaming is my closing keynote. Not a lot of syntax in here, but a new way of looking at some of the things you do at work, and how to approach those, that you may find helpful.

Going to conferences in person has many advantages, and I'm glad we're solidly back to doing that. But for the ones you can't attend, you can at least watch the sessions, and I highly recommend that you do.

Kate

The agenda for the Qt World Summit has now been released.

I'll be doing a half-hour version of a talk I've given only once before, "Am I a Good Programmer?" Many people have told me this is something they worry about pretty often.So at the end of November, we can discuss it together.

I've been lucky enough to speak in Berlin at several different conferences and I'm looking forward to being back there again. Would you like to join me? You can even get a discount of 10% if you use the code QtWS23_Kate -- register here.

Day 3 began with a terrific keynote from Jessica Kerr, I can write the code. But getting something done is another matter. I was so thrilled when she agreed to come and do a keynote, and this one didn't disappoint. I took pictures of several slides, always a good sign.

After a break it was time for Tony Van Eerd with Value Oriented Programming Part V: Return of the Values. There was plenty of pop culture here but also some darn good advice about making good abstractions, and what's good about them. Then out for lunch again ... I deliberately chose something different on my second trip to the market.

The afternoon started with Conor Hoekstra and New Algorithms in C++23. Conor makes these things look easy -- perhaps they actually are? Then the closing keynote, from Timur Doumler, called Contracts, Testing, and the Pursuit of Well Defined Behaviour. We sure have plenty of undefined behaviour to deal with:

Another amazing day in Toronto! Let's talk about what sessions I went to so far.

I started with Patrice Roy's Moving an Existing Project to C++ 20 for Fun, Beauty… and Results!. The first part set up a problem and showed some C++17 code to handle it. I was a little impatient during this part, because it was a lot of code and I would have done some of it differently (because I am doing C++20 which is the point of the talk) but I did notice that it was carefully written to be fast and readable. Then the fun started as things got shorter, simpler, and (proven with some measuring) faster using C++20 goodies.

Next was Ben Deane with Calendrical C++: std::chrono, History, Mathematics and the Computus. This very entertaining talk took a problem few of us really face in code (when is Easter next year?) and used it to show off what chrono can do with dates. Probably my favourite slide was the one to show when Thanksgiving is. When you get to it, you'll see why.

The first break of Day 1 was the "Canada Snacks" -- see the published menu for details. I've never put a blackberry on a Nanaimo bar, but they certainly were delicious.

I enjoyed And Then() Some(T) by Victor Ciura a lot, even though I had to duck out early. If you would say no to "are you using higher order functions today?" this is the talk for you. Because you almost certainly are, and knowing that will make a lot of things easier to understand.

For the last talk of Day 1 I had planned to attend Rud Merriam's A Journey into Ranges, Views, Pipelines, and Currying but some last minute schedule juggling as speakers ran into travel problems put it up against Timur Doumler with C++ and Safety. Safety is a timely topic, so I'll wait for the video to watch Rud's talk. Timur did an interesting review of what the word "safety" even refers to, why governments are starting to have an opinion, and whether C++ can ever be proven safe -- and why you should care.

We wrapped up the day with the conference dinner, a nice mix of old friends and new, speakers and not, and good food. I enjoyed the conversations a lot!

Day 2 started with a keynote from Ben Deane, Optimizing for Change. Some excellent advice in this talk even if I did find the dark background a bit of a challenge on some of the code slides.

I had an online meeting I couldn't miss, so I didn't go to another morning session. After my call I walked over to the St Lawrence Market to get some lunch. I wish more conferences were fully in the towns where they are held, and made it simple for attendees to walk out and experience a little sunshine and access a wider variety of food options.

The afternoon had more tough choices, but I went to Why Good Code is Relative by Daniel Withopf. A good summary of why you can't "just write it the fast way" and some solid code samples about how to actually follow advice like "avoid heap allocations."

Then I went to Get() into Retroactive Static Reflection by Vincent Tourangeau. This was a slideless talk, bopping around in a lot of surprisingly-readable code that showed how to get properties, introspection, and a lot of other things you think C++ doesn't have -- and all with C++11. I know I'll be watching the video when it's out because there were a few moments where I wanted to rewind and see something again!

For my last session of Day 2 I went to Writing C++ to Be Read by Vincent Zalzal. I really enjoyed this talk! It's the sort of talk I would give, but Vincent included a number of excellent points I had not made or heard before. He also had fantastic slides, with highlights to point out the parts he wanted to draw attention to, and good examples.

That left the Lightning Talks. Wow, these were so good! As always, some were funny, some showed something we needed to learn, and some were highly personal. I've seen a lot of lightning talks and I always get a lot from them. But I don't remember lightning talks from student volunteers and members of the organizing committee anywhere else. Worth staying up for!

Next, one more day!

Kate

So great that the second year of CppNorth has really happened, and started so darn well, too!

We started planning year two even before year one had happened, with a "next year" folder, and never really stopped. If you thought it was challenging to plan and host a conference with a pandemic still underway, that's nothing compared to doing the same thing during -- what are we calling it? -- an "economic downturn"? Getting attendees and sponsors took a lot of work, and luckily a pile of people who aren't me did that work.

Me, I showed up on Day 1 and did a keynote. I really enjoyed it, too. I'll post again when the video is up ... if you're an attendee you should be able to get the slides any time now.

This is 90 minutes of "stuff I've learned" like "Take Notes in Meetings" and "Always Take a Moment to Check" (aka Shift Left but for people) and the like. Many people told me it was helpful, which is very reassuring.

Kate

I had a lot on my plate when the MVP renewals appeared July 6th, but I'm delighted to number myself among this illustrious group again. I'm never worried that I haven't done enough for the C++ community, but I do sometimes worry if the C++ community is the target audience for the program any more. Still, I suppose it must be, since they renewed me.

I updated my profile on the MVP site a little.

Kate

From time to time I think it's wise to summarize the courses I have on Pluralsight. There is a link on the side you can use to get a free trial if you want to take any of these. Because I redo most of the courses each time a new version of C++ becomes widespread, there are quite a few courses with similar names. Here's a quick summary.

If you are using the latest version of a major compiler, you are on C++20. These courses have been updated for C++20:

• C++ 20: The Big Picture This is an overview covering "what is C++?" and "what is it used for?". If someone has suggested you learn it, start here to understand why you might want to. The title means that it's up to date to C++20, not that it only covers C++20. The actual content is equally applicable to older versions of the language.
  
• C++20 Fundamentals is more properly "the fundamentals of C++ including things that were introduced in C++20". This is an introduction to the ideas, syntax, and standard library. At seven and a half hours it can't cover absolutely every corner of the language, but it does cover what you need to call yourself a C++ programmer, and get started writing real code. This course assumes you already know how to program. If you don't, try Learn to Program with C++ 17 which will cover the building blocks of programming languages like loops, functions, and objects while teaching the C++ syntax and library. Afterwards, you can take Fundamentals to fill in any gaps.
  
• C++20 Algorithms Playbook again covers up to and including C++20, so plenty of things that have been around for decades, but it does have a lot of content that is C++20 only, because ranges made such a big difference here. If you're not on C++20 yet, take the C++17 version, listed below. Both versions are designed to convince you to stop writing raw loops and start using the many useful functions provided in the standard library. I demystify iterators and show you the benefits of using library code instead of rolling your own.

Time for an update on the conferences I'm doing in 2023.

In April I did the closing keynote at ACCU, Grinding, Farming, and Alliances How words and ideas from casual gaming can make you a better programmer. My idea here is that certain things you are fine with in games, like "daily housekeeping", don't feel the same in your job. If you could feel better about them, you might be happier or more successful. Also, games pull on strengths like altruism and responsibility to get you to do things -- can your job do the same? Can your harness that to be more successful (however you define success) or happier at work? This talk was recorded and I expect it on the ACCU Youtube channel some time in June.

Next up will be "my own" conference, which is to say the one dearest to me as well as geographically nearest, CppNorth. There's still time to register for this: it will be in Toronto at the King Edward Hotel. July 17th and 18th are preconference workshops, and the 19th, 20th, and 21st are three jam packed days of sessions with evening activities Sunday, Monday, and Tuesday. If you live in and around Toronto this is your chance to see famous speakers (and discover some new ones) without having to fly a long way. I recommend you get a hotel room though, so you can truly immerse yourself in the conference while you're attending. My keynote is Steps To Wisdom: some tips I want to share with you that I earned through hard experience.

In September I'll be returning to NDC Techtown, this time to deliver the closing keynote on Day 1. These days I choose conferences based on many factors and small friendly ones like CppNorth and NDC Techtown really appeal to me. Both attract very good speakers and I expect to learn things -- I know I did last year!

In November I'll be doing something I haven't done before -- I recommend doing something new at least once a year no matter how old you get. In this case it's Qt World Summit in Berlin, where I will have a small keynote. I look forward to new people and new ideas from this experience, and hope to reach some people who haven't heard me speak before.

It's not too soon to think about the 2024 season, for me anyway. If you'd like me to speak at your conference, you can see many of my previous talks on my YouTube playlist. Please check my Speaker Kit for the details of my preferences.

See you at a conference, I hope!

Kate

I've been working away for the last few months completely overhauling my C++ Fundamentals course at Pluralsight. Of course I updated everything for C++20, but I also added a module on error handling options, tweaked most demos, and lightened the overall look and feel. I'm really happy with how it turned out.

Here's the table of contents:

Leaving pointers almost till the end may seem like a shock, but this is how I teach C++ these days and it really works well.

As always, if you need a trial code, look for the image in the sidebar here to get a free trial and give it a whirl! I had a great time writing and recording it and hope you enjoy watching it.

Kate

Maybe you hadn't heard? There's going to be a C++ conference in Toronto this summer. It's very exciting! I'm helping to arrange it. We've got a great venue (the King Edward) and are busy building a program right now that includes breakouts, workshops on concurrency, generic programming, and game development, plus entertainment in the evenings and plenty of special extras. I want to see Canadian C++ programmers well represented, and hope we attract people from further afield as well. Toronto in the summer is warm, fun, and light well into the evening.

Right now, the early bird price of $925 is in effect. After we announce the full program in April, the regular price will be $1250. So you can save a lot of money if you trust us to put together a great conference program for you (and we will!). You'll save enough to be able to pay for the speaker dinner, a conference Tshirt, and so on. And you'll let us know that we'll get the attendees we need to put on a great show.

Registering early helps us do things like make deposit payments to our vendors. We don't have a surplus-from-last-year, because this is our first year. So support from the community will really help. Why not check your schedule for the third full week of July (the conference is the 17th to 20th, and there are two-day workshops over the weekend of the 15th/16th) and arrange now to join us?

Kate

I have missed conferences for a long time now. I did a few online talks, but it's not the same, not at all. This year, ACCU are holding their conference as a hybrid event. This means while many will gather in Bristol for all the networking, friendship, serendipity, and other benefits of being in person, others will join us online. I think that is great: for many people traveling to a conference is not an option -- for reasons of money, physical limitations, visa restrictions, and so on -- and being able to attend online is terrific for anyone who can't travel to the conference. For me, it feels safe now to travel. I have traveled twice during the pandemic: to Singapore in Feb 2020, when it was underway but hadn't really reached Canada yet, and to Singapore again in Nov 2020 for urgent family business, complete with two 14 day quarantines and multiple tests. I'll be taking all possible precautions, and I think it's going to be safe.

The schedule has been published and my talk will be Friday afternoon. I've booked my plane tickets and hotel room, and am starting to build out the list of talks I plan to attend and people I want to meet. By the way, Guy Davidson will also be there (doing a keynote, in fact) so if you're hoping to get your copy of Beautiful C++ signed, that's a good opportunity! I think there will probably be a table for #include <C++> but even if there isn't, watch our for our shirts and say hi!

I'm going to talk on Abstraction Patterns: things I've learned to spot in code that show a missing abstraction. Unlike the sort of "business objects" that you design at the start of a greenfields project or a major expansion, you don't need deep business knowledge and a long meeting with a business analyst to design these: the code will show you what to do. Come and see what I've found and if it can help you.

Kate

It's true! I helped to write a book! Another book! (Do not ask me what this brings the total to, I truly do not know.) This one is about some of the C++ Core Guidelines.

Opinions vary on when it will be available: maybe the last week of 2021, maybe early 2022. You can pre-order from the publisher if you can't wait. There will be both an ebook and a paper version.

It's Guy Davidson who wrote it really; I have been a sort of editor and suggester and inspirer most of the time. If you liked my CppCon 2017 talk, 10 Core Guidelines You Need to Start Using Now, you will love this book, and not just because it's three times as many guidelines. Guy has included explanations of the 30 guidelines we chose, along with plenty of examples, the occasional diagram, and stories that put them into context and show you why it matters how you write certain constructs and why you should avoid some aspects of the language entirely. We are delighted that both Bjarne Stroustrup and Herb Sutter, who edit the Core Guidelines, reviewed the book, gave us helpful comments on the text, and wrote a foreword and an afterword for us as well.

I learned things writing this. You will learn things reading it. It may well change the way you approach code. That is one of our goals. The other is to get you trusting the guidelines and dipping into them when you have decisions to make about how to implement something. If these 30 are useful and good (and they are!) then imagine what else is waiting for you when you're ready!

 Please spread the word far and wide.

Kate

ps: the full title is quite a mouthful. We're thinking of RainbowFlower as a nickname for the book. What do you think?

This summer has featured a lot of personal busy-ness and not a lot of work things to announce. One nice thing that has happened is my renewal as an MVP.

According to various "kate bio.txt" files kicking around my hard drive :-), I was first awarded in January 2004. So it will be a while yet until the blue 20 year marker arrives. The program has changed a lot over the years, but it's still relevant to me and a great source of information from the Visual C++ team.

Kate

In April, I did my Naming is Hard talk at ACCU 2021. I'm getting better at doing talks online and handling interactions, at least I think I am :-). The recording is now online, so if you weren't at the conference, you can watch the talk. Being there is still better, even when it's digital - being able to chat to other attendees and the presenter is always going to be better than just watching a recording.

I added the talk to my youtube playlist of conference talks, so if you like that one and want some more, take a look!

At the start of the lockdown, Pluralsight made its huge curriculum free to help those who were suddenly needing new skills to find a new job during the pandemic. I saw a huge number of views of my C++ course for those who don't already know how to program. It was ironic, because I was busy updating that course, a process that is finally complete.

Please check it out on Pluralsight. The new course is called Learn to Program with C++. (The similar-but-not-the-same Learn How to Program with C++ is the old one.) Here's what I did to the 6+ year old course:

• redid all the demos in the latest compilers (Visual Studio Community Edition on Windows; Clang on Ubuntu and Mac)
  
• added more Ubuntu and Mac versions of demos and tested EVERYTHING on all the compilers
• moved content to slides and then just demonstrated it in the demo, instead of trying to explain concepts during long demos where there's no typing or other "demo" action
• took a more "modern C++" approach wherever I could
• improved the names in my sample code, trying not to have a,b,c and the like if I could
• added some explanation of "make" and removed rather a lot of "how to get Visual Studio to be nicer" because it does that itself now
  

Plus I just generally tweaked samples, slides, and demos throughout the whole course based on comments I've had from new learners since the original publication. It's a better course.

People often say that C++ cannot possibly be taught as a first language, but that's wrong. Modern C++ is not that hard. This course is a little over 5 hours long and covers most of the syntax and punctuation you need, functions, classes, type safety, using templates from the STL like vector and string, and even touches on const and RAII. If you want to learn C++ for whatever reason, don't let someone else tell you that you must go and learn some "scratch" or starter language first before coming back to what you really want to learn.

If you already know one programming language, and concepts like "if" or "loop" then you don't need this course. C++ Fundamentals Including C++ 17 is for you. It covers even more syntax, punctuation, library, and design aspects of the library.

As always, if you don't have a Pluralsight subscription, you can get a ten day trial by clicking the big white square on the blue sidebar of this blog. Enjoy!

Lately a lot of people have been asking me for help as they write C++ code. I’m usually happy and able to help. There are times, though, when I either cannot help, or choose not to help. I thought it might be helpful to explain some of these a little. It’s quite likely that other members of the community have a similar set of guidelines in their heads for when they do and don’t help people with code.

Warning: this is long. I think it's worth reading it all. You want a TL;DR? It’s this: if you want free mentoring and consulting from successful people, you can have it! All you need to do is ask. But if you expect your helpers to do most of the work in helping you, and to take instruction and direction from you, you’re going to get a lot less help than if you know how to be helped effectively.

The first choice is where and how you ask. People often email me, message me on LinkedIn, DM me on Twitter, DM me on the #include <C++> Discord, and so on hoping to get personalized, instant, one-on-one help from me. That’s not a good use of my time. I prefer to help in places where others will see the question and the answer. That helps more people. It also enables more people to help – so it produces better advice as well as helping those people learn and grow. Often, I learn from the times when other people chime in. So I encourage you to post on StackOverflow (if you have the sort of just-one-question, just-one-right-answer problem that fits there), or on the #include <C++> Discord, or some other public place where a number of people can see the question and the answer over time.

The rest of the issues have to do with how much work the person expects me to do, or how much they save me. Think about how you ask the very first thing you ask. Compare “here is a zip of all the files in my project can you tell me what’s wrong with it?” to “here is a link to an online compiler (Godbolt, wandbox, etc) showing a compiler error on line 43 that I don’t understand. Can you tell me how to fix that error?” Expecting someone to install things, trawl through multiple files, guess your question, and then solve your problem and explain it all to you is really too much. At least tell people what your problem is! Often people ask for help saying something like “it’s not working” or “what’s wrong with this?” and I don’t even know if it’s a compiler error or a runtime error or running fine but calculating the wrong answer. So before you post on the discord, for example, try to have a single crisp question, not just “help, it’s not working.”

• Show us your code, and your errors. And not as screenshots! You can copy the code into an online compiler like Godbolt or Wandbox, or if it’s less than 20 lines or so, paste it into the chat window – but please learn how to format it as code when you do that. Copy and paste the errors as text. That makes them much easier to read, and lets us copy and paste parts of them while explaining things to you. If you can’t show your real code because of how big it is or because it’s work-related, create a tiny example that shows the same problem and show us that. Stack Overflow has some tips on how to do that.  Whatever you do, do not free-type some code into the chat window that you think is the same as your problem, and then whenever people point out missing semi colons or undeclared variables, reply “oh yeah, that’s not really my code it’s just something I typed to give you the general idea.” Compilers (and runtimes) are picky and asking for help with something that’s vaguely like your real code (but not really) is pointless.

Now let’s assume you manage to get a conversation going with someone who is trying to help you. They solved that compiler error, for example, but now you have another one. As part of this process, I often make suggestions to people that they reject. I think they believe the suggestions are to make things easier for themselves in the long run, because they say things like “I can do that once it’s working.” I then have to spend a lot of effort explaining that I want them to do these things so that I can help them get it working. These suggestions include:

• Write good variable (and function) names. If your variables are all called i, n, c, r, s, and so on – I don’t know what they represent. If I ask you to change those to words like next, rate, total, and so on, or to words you think of yourself, that’s because I can’t understand your code (I don’t know the problem you’re trying to solve) without some help. Good names aren’t a someday thing that you paint over working code once it’s all good. They are how you make code other people can read. And you’re asking me to read this code. Make it readable.
• Use a debugger. When I ask “have you looked in the debugger to see the value of a before the loop?” an answer of “I don’t know how to use the debugger and I don’t have time to learn that today” is a great way to end our conversation. Real programmers use the debugger. We don’t have some magical compiler-simulator in our heads that can read code and tell you if it compiles or not, and we don’t have a magical runtime-simulator either. Sure, maybe I can tell at a glance that a is 0 before the loop and that’s why it’s not working, but in that case I would tell you so. It’s more likely that I want you to quickly check and see if it’s 0 or not. When you refuse to debug, you’re making it so much harder to help you. You need to learn to use whatever debugger is available to you, and you will probably save enough time today to make up for the time it takes to learn it.
• Add some tests. You don’t have to go learn a whole unit testing framework. But if you’re writing a function to do whatever, work out by hand what it does for simple values, and write a test harness that passes it those simple values. Then you can debug the test harness and see what the function returns and confirm whether or not it works for simple values. Whether you’re reversing a string in place, calculating the Fibonacci sequence, calculating sums of things, whatever, you should be able to think up simple test cases and test your code with them. And eventually, you should be writing tests as you write your code. It’s a good habit you can build now.
• Break up big things. You don’t have to embrace full OO or write functional programs, but don’t give me 1000 lines of code and ask me to load it into my head. Write some functions. Heck, throw in some comments and some blank lines. Show the structure of your code so it’s not a wall of text.

• Try the substitutions people tell you to try. A lot of times, people who are having a hard time don’t want to learn a new thing. I run into that situation all the time myself. I’m already frustrated and I’ve spent longer than I meant to and I can’t understand any of it, I don’t want you to tell me to go learn yet another thing right now. I have gained some wisdom over the years though, and it includes this: sometimes jettisoning all that half-understood not-really-working mess and doing something simpler is the best way forward. If someone tells you that vector would be better here, and offers you a few lines of code to use, just digging in your heels and refusing to try it isn’t going to lead you into learning. If you’ve got a problem because you’re trying to manage memory yourself by hand but you forgot about copying and so on, then using a smart pointer, or dropping the pointers altogether and using an object on the stack, is going to make a whole pile of work just fall away. The person advising you to try this knows how much effort it will save. You don’t, that’s why you came for help. It’s really frustrating to see a beginner insist on doing something the hard way (for no benefit), do it wrong, and refuse to accept any help other than “here is the precise and exact code to do that thing the hard way.” I don’t want to do things the hard way any more: why would I type out all the code for you?
• Try things that don’t matter to you, if the person who is helping you tells you that your code is harder to read the way you have it. Things like initializing member variables in a constructor with the : syntax, not between the braces, or adding some using statements – these may not matter to you, but making things too hard for a busy helper may mean that helper is too busy to help today. Or ever. I don’t want to teach you bad habits, I don’t want to teach you to “pretty things up” only once it’s working, and I don’t want to exhaust myself reading difficult code to spare you the trouble of doing the right thing. Also, when a person asks for advice but never takes any of it because they’re sure it’s not actually relevant to their problem, eventually the advice-giver will stop giving it. It’s pointless.
• Write your own code. If I tell you “the problem is that you’re not initializing x” don’t ask me to edit your code for you or paste in the new version of the function or whatever. You need to understand what you’re doing and that comes from writing the code yourself. If you don’t understand how to fix a problem that someone has told you about, ask them “how do I fix that?” If you can’t understand their answer, say “I don’t know what [whatever] is, can you explain it or show me?” Don’t just ask “what would that line of code look like?” That feels like you’re asking me to even do the typing for you.
• Work with whoever is talking to you. Maybe when you first ask, one person has a couple of thoughts, and those are good, but while you’re changing your code to see if that works, someone else chimes in. That’s great. It’s a group chat. Don’t tell them that you’re working with the first person or anything like that to reject their help. Consider all the suggestions you get. If you’re talking to someone and then they stop, that’s cool too. Many people pop into chat for 5 or 10 minutes waiting for a conference call to start, or while they’re eating lunch, and don’t stay long. People get called away from their keyboards. Don’t start pinging the person trying to bring them back or ask if they have any more thoughts or saying you’re still stuck. You can tell the room or channel as a whole that you’re still stuck. Maybe someone else will have some ideas. Your problem may end up solved over an hour or so with three different people. That’s a win!

I know, that’s a lot of advice. Thing is, you can get a lot of help from strangers on the internet, if you ask the right way. If you ask the wrong way, most people will just shrug and say “looks like you have a problem” and move along. They won’t even tell you why they’re not helping you! To get the marvelous free help, and to truly join the community, you have to put in a little effort. Trust me, it’s worth it!

Every once in a while, I make a big change in how I plan and manage my speaking engagements. Early in the last decade, I decided to speak only at conferences I would happily pay to attend, and that improved my life dramatically. Instead of trying to justify a week away from home and the office in which I would try to keep up on emails from a hotel room or a hallway couch, while surrounded by people who didn't care about the stuff I cared about, I started looking forward to a week of learning and growing, of coming home knowing more than when I left, and of meeting my heroes and getting to see my friends.

While this was an important change, it was only a change in my decision criteria, and not in my overall process of deciding where to speak. I would get an email, or see a tweet, or otherwise become aware that a conference was going to happen, and then I would decide, on a case-by-case basis, if I wanted to submit to that conference. Sometimes I would have to decline because I had already submitted to another one at roughly the same time, without realizing the overlap. In mid 2019, I changed that. I listed out all the C++ conferences I knew of, and roughly when they happened. Then my partner and I went through the list, noting when various family events are happening, when we want to go on vacation, and other "big rocks" that conferences have to fit around. We talked about how many conferences I wanted to speak at, and whittled down the list to that many.

Now, as each conference opens a Call for Papers, if it's on my list, I submit, and if it's not, I don't. Of course, my talks aren't always accepted. I set myself a goal to speak at two non-C++ conferences in 2020. I was invited to one, but after I agreed they changed their dates and that conflicted with something else I had accepted. I submitted to another and they declined my talk. But one has accepted, and I have accepted another invitation, so I will be speaking at two non-C++ conferences for sure.

Expect to see me at:

• January, Montreal: CUSEC 2020 (Canadian University Software Engineering Conference) - keynote (and a Meetup while I'm in town, come ask about technical speaking)
  
• March, Bristol, UK: ACCU - Naming Is Hard, Let's Do Better
• May, London, UK: SDD - Naming and Emotional Code

I'm thrilled to announce my latest Pluralsight course:

Here are the modules:

• Course Overview
• Modern C++
• Standard Library Containers
• Lambdas
• Standard Library Algorithms
• Move Semantics
• Exceptions

• On Sunday, I am doing a preconference workshop (you can still get a spot) with John Lakos and Andrei Alexandrescu
• After the precon I hope to relax at the TShirt dinner. Pack a Tshirt that says C++ (or bring your badge, or a piece of paper on which you wrote C++ yourself) and choose a restaurant from the list that should be published by the time we all get to Colorado. When you arrive, ask where the other C++ Tshirt people are, and make some new friends! I'll be tweeting my plans just before I head out.
• Then it's back to the shiny new venue for the Registration Reception. Even if you're on East Coast time like me, make an appearance, see some friends or some of your heroes, there will probably be treats, and you'll be all set for the morning. Knowing the venue a bit is going to make you sleep better, and having your badge already will let you sleep longer.
• Monday I will be attending talks and spending time at the exhibitor table for #include<C++>, an organization working to make the C++ community more welcoming and inclusive. Come by and get a sticker! Buy a shirt! And you know, attending talks and hanging at the #include table is what I'll be doing all 5 days.
• If I manage to stay awake, I'll go to The Committee Fireside Chat after dinner. If there is something you always wanted to ask the people who create the C++ standard, here's where that happens.
  
• Tuesday and Wednesday it's talks, talks, talks! I predict I will go back to my room for a nap at least once. It's a strategic choice that lets you actually experience the post-nap talks instead of drowsing through them and needing to watch the recording in the end.
  
• Wednesday night is the #include<C++> dinner and panel! You can register for this on Eventbrite as part of registering for the conference. I'll moderate a discussion about some of what we've achieved in just two years, and what some of us would like to see next.
  
• Afterwards it's Lightning Talks. Everyone loves the Lightning Talks, they're always fantastic. I will try my best to stay up for them.
  
• If I can, I'll come super early on Thursday and Friday for recordings of CppChat. And stay all day for talks, of course.
  
• Thursday night is the Speaker's Dinner. And there's a planning meeting after that. But I might need an early night, because...
  
• Friday morning I have my one breakout session: Naming is Hard: Let's Do Better. And like last year, a lot of really good content is on Friday. Don't even think of leaving early. Fly home Saturday morning, you won't regret it.

See why I call CppCon an intense conference? 12 or 13 hours a day, every day. And no time for sightseeing! But oh my goodness the things I will learn, the people I will meet, and the fun I will have. See you there!

I just published a small course on Pluralsight called Advanced Debugging with Visual Studio 2019. It covers IntelliTrace and Code Map, two features that are only in the Enterprise Edition of Visual Studio. Many people don't know about them, so I put together a quick introduction.

Here are some of my other current courses:

• Visual Studio 2019 Getting Started - what you need as a new user of Visual Studio to start using it. There are a variety of other Visual Studio courses, and pretty much all of the material from my 2017 one is still applicable, so don't take just this one or you'll be missing some really powerful techniques.
• Beautiful C++: Updating Legacy Code - I really enjoyed writing this course and if you maintain old C++ code, I think it will make your life a lot easier. It discusses both specific patterns to update (and why) and overall strategic approaches (not mechanically replacing every incidence of one pattern with a newer pattern.)
  
• C++ Fundamentals Including C++ 17 - this is the go-to course for developers who want to learn C++ today. Whether you never did any, or did some a decade or two ago, this course will cover the syntax, library, and best practices you need. If you've never programmed in any language, try Learn How to Program with C++ instead.
  
• Using Stack Overflow and Other Stack Exchange Sites - we all go to Stack Overflow when we're stuck. But a lot of us are bad at it, because it doesn't work like other sites. Take a little time to improve this skill and you'll get better and faster answers. You might even become one of those high-rep users who others admire!
• Beautiful C++: STL Algorithms - Stop writing raw loops and you will get more readable code with less effort. The library has so much waiting for you and this course will help you make sense of it all.

In early April I was lucky enough to go to Bristol in the UK for the annual ACCU conference. This has been an aspirational conference for me, one I attended before speaking at and am always delighted to attend. This year I was invited to keynote, and it turned out to be the closing keynote, which meant I was not done with all my talks until the conference was over! Nevertheless I enjoyed the week tremendously.

I flew to England overnight Saturday night. People often ask me how, given the fatigue issues I have left over from the whole surviving incurable cancer thing, I am able to travel. One reason is that when I travel, I only travel on travel days. I don’t try to work at the airport, on the plane, etc. I read a book or listen to music or just relax. On overnight flights, I sleep. I also schedule a few days to adjust to the time zone without having to think hard or meet important deadlines, like finishing my talk. On this trip, I spent two days visiting Cardiff, which is actually where I was born, with my sister who is planning to move there. It was marvelous fun watching a family explore and discover their new home town, and going to places I have seen on TV or in pictures.

Tuesday I did a private corporate talk about #include<C++> and diversity issues. It was very well received and I might offer it to other companies as a result. I always buy a train pass when I go to the UK and it got a good workout on this occasion. Back in Bristol I was able to relax and know I was ready for the conference.

After a lovely opening address by Russel, we had an illuminating keynote from Angela Sasse.  Security can’t be left until the end or handled by a separate group who fight the developers. Afterwards I took some time to meet up with more friends and spend some time at the #include table. After lunch, a very good talk from Jonathan Boccara on reading unfamiliar code.  I loved the map analogy and the way he showed using a call stack to increase your mapped area. Then a workshop from Gail Ollis on Helping Developers to Help Each Other which really brought home to me once again how important tactile artifacts – things you can pick up, put down, wave around, put next to each other and so on – can be to encourage open and complete communication.  The recording stops when the hands on part starts – just one of those things you can only get by attending in person. The talks wrapped up with Lightning Talks and I did one – my first time doing so at ACCU. I was not able to stay up for the evening reception beyond a quick “hey! Great to see you!” to a handful of people. There were plenty of talks I couldn’t get to – recordings for me to watch later!

Day 2 started with a Herb Sutter keynote.   I’ve read the paper but was really happy to hear it as a talk, and to hear the motivations behind enabling more people to use the whole language.  Then I needed some down time before my talk right after lunch. I gave an updated version of “Nothing” and as always at ACCU got some great questions that will go into the next version of the talk – or some other one.  Then I kept to tradition by doing the Pub Quiz, entertaining as always for the don’t-write-this-at-work code and marveling at how some folks know a lot of dark corners! Another round of lightning talks and an early night, meaning I couldn’t attend the Bristol Girl Geeks dinner as I had planned.

The Day 3 keynote was low on code and high on insight as Paul Grenyer talked about growing a community while dealing with the ups and downs of life in general.  Then to a fascinating talk by Dom Davis about communicating, with significant meta content that I really enjoyed.  I spent the lunch break at the #include table, and then dove into a variety of little talks – 15 and 20 minute ones. I was starting to tire and didn’t pay as much attention as I should have, but let me recommend Alex Chan’s reminder that the tech we build can hurt people when it’s being used as designed.  I took a break to be ready for the Conference Dinner where I was able to catch up with old friends and meet a few new ones.

Finally Day 4. I started with Kevlin Henney and a talk with a similar title to my “Nothing” but very different content.  Another break, another lunch at the #include table, and then some down time before my closing keynote. I updated the beginning of this talk since the C++ on Sea keynote, and I think this improves it. More great questions after and I think more material to work in there somehow. Then the close of the conference, a certain amount of hanging around not wanting it to end, and up to my room for another early night and to get ready to go.

Sunday all I did was take the train to the airport, fly home (sleeping a little on the plane) and drive home. A lot to process, as always after ACCU. And when I got home, a lot to catch up on, which is why this has taken a few weeks to write up!

My latest Pluralsight course is live!

I start by talking about strategy - what parts to update, what general approach to take, and so on. Then I present a number of specific tactics, like using the preprocessor less and the compiler more, actually using C++ instead of just C, and using C++ features that were added in C++ 11, C++ 14, and C++ 17. I show you code examples for the changes I am suggesting, and explain why specific changes produce code that is more readable, understandable, and maintainable.

As always, if you don't already have a Pluralsight subscription, feel free to click the large white box in the margin and start a free trial. I hope you like the course, and tell your friends about it too!

Next year, I'll be keynoting a new C++ conference, C++ on Sea. I'm really looking forward to it. A little while ago, they ran a "tweet why you want to go" contest for a free ticket, and said that if the winner already had a ticket, the conference would help the winner give away the ticket.

Can you guess where this is going? I won the ticket. I already have one, so you can win mine. Here's what you need to do:

• Choose a way to "give back" to your community before, during and after attending. This might be blogging, tweeting, hosting a local meetup where you talk about what you saw and recommend specific talks for others to watch later, or even activities at the conference like giving a lightning talk.
• Gather supporting links - to your blog, your repo, your YouTube Channel, the meetup site, and so on
• If your plan won't fit in a tweet, put it somewhere that it will fit. Include lots of links - I want people to find your blog, channel, meetup etc even if you don't win
• Tweet me (@gregcons) with your plan or a link to it. I will retweet. Focus on what you will give if you are able to attend the conference.(It's not that I don't care whether you are deserving or can't afford to go or whatever, I do, but I am going to focus on how you will share your good fortune with others.)
  
• If you're not on Twitter, post on my public Facebook page. You can't just email me because the idea is to promote those links to blogs, channels, meetups, and suchlike.

That's it! I'll choose someone, probably by filtering to everyone who is offering to do something generous and then randomly choosing one, but I reserve the right to choose the single person who comes up with the most amazing plan. I'll tell the conference that you get my ticket.

Fine print: this is just admission to the conference. Not travel or hotel. Not paid time off work. You'll need to cover that yourself. I suggest that telling your boss you won the ticket because of your community involvement might be quite helpful as far as that is concerned :-). And while I can't force you to keep your promise, I will remember if you do, and that will probably be a good thing for you over and above the rewards of doing those good things for the community.

Good Luck!

Kate

Here's what's coming up over the next few quarters:

• August 27-30: NDC Techtown (two talks)
  
• Sept 23-29: CppCon (preconference day; main conference talks not yet announced)
• Oct 18th-19th: Pacific++ (two talks)
• Submissions are still open so if you want to join me in Sydney as a presenter, get on that!
• Nov 15th-17th: Meeting C++ - I will not be speaking here (I just can't fit it in), but I want you to know it's happening
• Feb 4th-6th 2019: C++ on Sea (keynote at this brand new conference)
• April 2019 - ACCU (nothing announced yet, but I plan to be there)

I consider it an absolutely marvelous problem that there are so many C++ conferences I can't go to them all! There are a number of smaller conferences that draw primarily from one country or region, and more meetups than I can keep track of. I'm open to talking at a meetup if I happen to be traveling to a city for business anyway, but I don't think I can get up above 5 or 6 conferences a year, especially if some of them involve keynotes, plenary sessions, or workshop days. It's a lot of work!

Hope I get to see plenty of people in these various places,

Kate

I had a very busy March and April, with travel and with preparing for those trips. So I forgot to mention that my latest Pluralsight course is now live! It's called C++ Fundamentals Including C++ 17 and it's an update of my C++ Fundamentals course. Here's what I changed:

• I made most of the demos a lot smaller, by breaking them into pieces or by putting some of the material on slides instead
• I made the slides less text-heavy, again mostly by splitting them up
• I added diagrams to explain things that needed them
• I added some C++ 14 and 17 content
• I switched to a consistent "const after" style (aka east const)
• I double checked every line of code for good style and consistency

I'm really pleased with the result. If you've already taken C++ Fundamentals you probably don't need to take it again, but I hope you'll recommend to others that they take the new one. I think it makes learning C++ less daunting than some other approaches do.

Kate

ps: don't have a Pluralsight subscription? There's a link over there ------->  for a free trial.

The schedule for ACCU has now been released, and the Feb 20th early bird registration deadline is approaching, so I thought it was a good idea to mention my session there.

Simplicity: not just for beginners

Many people say that simple code is better code, but fewer put it into practice. In this talk I’ll spend a little time on why simpler is better, and why we resist simplicity. Then I’ll provide some specific approaches that are likely to make your code simpler, and discuss what you need to know and do in order to consistently write simpler code and reap the benefits of that simplicity. Code samples will be in C++ and some material will be C++-specific.

I'll be joined by dozens of amazing speakers and the topics will be wide-ranging. It's not all C++, and I'm looking forward to a little mind-expanding from some session I didn't expect to do so. The pub quiz and lightning talks will also be good fun. April 11th to 14th in Bristol - will I see you there?

This week, I’ve been in Salt Lake City for the Pluralsight Author Summit and the first-ever PluralsightLIVE event. What a great time! This is my first time on a plane in over two years, and it is terrific to be out traveling again.

Pluralsight takes great care of its authors and that started with a lovely box of goodies in my room the first night.

Tuesday we all got together to hear about the past growth and future vision for Pluralsight, and to get a sneak peek at some things that would be announced later in the week. And of course, for Aaron to get a selfie with the authors!

In the afternoon, we had open sessions where we learned from some Pluralsight staff we don’t normally get to meet, and from each other. What makes you a great author in the eyes of your editor and the other people who help to get your material published and live? How can you get your courses recorded faster? Geeky talk about microphones and other tools of our trade, of promo videos on YouTube, and so many other things we all really wanted to talk about.

PluralsightLIVE itself started Tuesday night with a reception in the partner pavilion and an evening event I wasn’t able to stay up for.

That's my shirt being printed on the spot for me!

That's the very popular candy dispenser array.

I’ve been to a LOT of conferences and most of them look pretty generic. Here there was just so much effort showing: the fun activities like huge Jenga, Connect 4, and similar games, the couches everywhere (with power and USB ports so you could charge whatever you needed to charge), the large easy-to-spot-and-read signage, and more. It was clear the organizers were really caring about the wellbeing and happiness of all the attendees.

There were a lot of keynotes. Wednesday and Thursday both had keynotes the whole morning, and Thursday also had an afternoon keynote. These were entertaining, inspirational, educational, and really worth my time. I was especially looking forward to Joel Spolsky on Wednesday morning and he didn’t disappoint. He was funny and open. He also announced that Stack Exchange users will all get 60 free days of Pluralsight training. I hope some of them use it to take my Stack Exchange course! Then he liked my tweet afterwards so that was fun.

(If you want to take one of my courses, and don't have a subscription, there's a grey rectangle over the right that says Author: click it and you can get a ten-day free trial.)

When I wasn’t in keynotes, I was meeting other attendees and Pluralsight authors. Many of the authors are friends I haven’t seen in far too long, so it was tough to tear myself away, but I forced myself, because meeting learners is what this week was about for me. It was especially helpful to talk to managers and team leaders who want to know how their people are using their subscriptions. The Pluralsight IQ announcement [link] was very well received both by learners who wanted to show off their scores, and managers who wanted to track a team’s progress.

I took the C++ assessment, but I zipped through it a little too quickly and some questions needed more thought than I gave them. Still, I did ok:

After I tweeted my results, a whole pile of my C++ tribe also got their scores, and I even outscored a few! (Plus, I think they found a few bugs in the assessment – I’m going to get them fixed.)

The afternoon keynotes on Thursday wrapped up with Michelle Obama talking about diversity, education, children, and much more. I hadn’t heard her speak before other than sound bites on the news, and I was really impressed. She was warm and funny and willing to show irritation or frustration as well as the polished pleasantness I was expecting.

Next year’s dates have already been announced: the week of August 26th, 2018. I’m planning to be there. If you take Pluralsight courses (and come on, you should be taking Pluralsight courses) then consider it too. There was a lot of good content in a wonderful atmosphere, a chance to meet all kinds of interesting people, and a few days to put learning and growing front and centre – time well spent for me.

This year's innovation at CppCon is a Meet the Speakers Dinner Thursday night. It's pretty expensive ($100) because the venue is charging a lot for it, but here's your chance to relax over dinner with many of the speakers from CppCon. If you've registered for the conference but haven't bought a dinner ticket yet, please do! We want to meet attendees and this is a great way to do it. I've been an attendee at speaker dinners at other conferences and I have to say it's always been a highlight of the conference for me. Career advice from Bjarne himself over (excellent) dessert? Yes please!

I can't guarantee you Bjarne (or even me) but you will be asked if there's someone you want to sit with, and the organizers will do their best to accommodate you.

I am happy to announce that my submission to CppCon has been accepted!

10 Core Guidelines You Need to Start Using Now

The C++ Core Guidelines were announced at CppCon 2015, yet some developers have still never heard of them. It's time to see what they have to offer for you, no matter how much C++ experience you have. You don't need to read and learn the whole thing: in this talk I am pulling out some highlights of the Guidelines to show you why you should be using these selected guidelines. For each one I'll show some examples, and discuss the benefit of adopting them for new code or going back into old code to make a change.

Beginners who find the sheer size of the language and library daunting should be able to rely on the Guidelines to help make sane choices when there are many ways to do things. Experienced C++ developers may need to leave some of their habits behind. Developers along this spectrum could benefit from seeing what the Guidelines have to offer, yet the guidelines themselves are just too big to absorb all at once. My examples will be chosen to be beginner-friendly and the focus will be on what's in it for you: faster code, less bugs, and other tangible benefits.

I am so looking forward to seeing "my tribe" again in Bellevue this year. I'm going on the field trip too! If you haven't registered yet, get on that!

I had to curtail my activities pretty dramatically in the second half of 2016, even in areas like mailing list participation or answering questions on StackOverflow. I was beginning to wonder if I would qualify for Visual C++ MVP again without conference talks or some of my other usual activities. No-one should ever assume they will be awarded; the program is always changing and our lives are always changing, so anyone can find themselves out of sync with the requirements of a program. However, I'm happy to learn that I have been renewed for 2017 and will continue to be part of this active community.

Looking forward to a terrific 2017,

Kate

I've started a C++ column in Visual Studio Magazine. I'm sure you've read plenty of C++ columns in your time - I sure have! I wanted this one to be a little different. So, here's what I've decided to do. For each column, I choose a guidelines from the C++ Core Guidelines, and then explain it. But the twist is that I'm not going through the guidelines from top to bottom - I'm picking guidelines whose explanations require a little language knowledge.

The first column just sets the stage and explains what I'm doing, and gives you a link to the Guidelines. The second, Don't Cast Away Const, explains the guideline, but also the consequences of const-correctness, a typical situation where you might find it hard to stay const-correct when you make a performance tweak to a running system, and the correct use of the mutable keyword. Not bad for explaining a four-word guideline!

I have a number of columns already written and plans to write more. Please check them out and spread the word!

I’ve been hearing that the new search and browse functionality on Pluralsight isn’t working for everyone, and that the sheer volume of courses makes some hard to find. So I thought I’d make a list of my current courses in the hope of simplifying things for those who want to learn something specific.

Visual Studio 2015: Essentials to the Power-User

This is the most recent Visual Studio course and it starts at the beginning and goes well past what most people know about Visual Studio. I’m confident that even if you use Visual Studio every day, you’ll learn something in this course that will make you more productive.

What's New for C++ Developers in Visual Studio 2015 Preview

This course was based on the preview, but works well against the RTM version of Visual Studio 2015. It’s C++-focused and just shows you what’s new compared to Visual Studio 2013.

Using StackOverflow and Other StackExchange Sites

Most developers find StackOverflow results whenever they do a web search for a particular error message, or some API they’re having trouble using. Many of them tell me that when they try to sign up and actually ask and answer questions, they have an unpleasant experience. Often, it’s because their mental model of the site does not match the way it actually works. This course will show you how it works, so you can get the answers you need and not feel rejected or hurt by the way these sites work.

Learn How to Program with C++

This course is aimed at people who have never programmed before. If you’ve programmed, in any language, consider C++ Fundamentals instead. If you don’t believe anyone can learn C++ as a first language, I’m ready to argue with you. Modern C++ is a simple and useful language that a beginner can learn and use well.

C++ Advanced Topics

This course is for the material I couldn’t fit into C++ Fundamentals. It’s presented as a number of things I want you to do, or stop doing, when you write C++ today:

• Avoid Manual Memory Management
• Use Lambdas
• Use Standard Containers
• Use Standard Algorithms
• Embrace Move Semantics
• Follow Style Rules
• Consider the PImpl Idiom
• Stop Writing C With Classes

C++ Fundamentals   and C++ Fundamentals - Part 2

I have other courses – on older versions of Visual Studio, for example, but these are the “big” ones for me at the moment. I hope this list helps you to find them. And remember, if you need a free trial, use this link. Click Subscribe, then Start 10-Day Trial, and you’ll be all set.

The first keynote at CppCon this year was Bjarne Stroustrup (who invented the C++ language) announcing the C++ Core Guidelines. They are on Github and once he announced them, as Herb Sutter reported in the second keynote the very next day, they quickly became a trending topic across all languages. Here is a description of the guidelines from there:

The C++ Core Guidelines are a collaborative effort led by Bjarne Stroustrup, much like the C++ language itself. They are the result of many person-years of discussion and design across a number of organizations. Their design encourages general applicability and broad adoption but they can be freely copied and modified to meet your organization's needs.

The aim of the guidelines is to help people to use modern C++ effectively. By "modern C++" we mean C++11 and C++14 (and soon C++17). In other words, what would you like your code to look like in 5 years' time, given that you can start now? In 10 years' time?

The guidelines are focused on relatively higher-level issues, such as interfaces, resource management, memory management, and concurrency. Such rules affect application architecture and library design. Following the rules will lead to code that is statically type safe, has no resource leaks, and catches many more programming logic errors than is common in code today. And it will run fast - you can afford to do things right.

To me, these guidelines are the key to getting across my fundamental message that C++ does not have to be hard, scary, complicated, or dangerous. The language may still say “it’s your foot!” but the guidelines, and the tools they can drive, are quite the opposite.

You probably know that Visual Studio has a static analyser built in. (You should, anyway, I’ve blogged about it.) It will catch things like this:

    int* p = nullptr;
    *p = 10;   

But it doesn’t mind things like this:

    int arr[10];        
    int* p2 = arr;

Two lines, two violations of the guidelines – I’m not initializing any of the elements of arr, and then I am using its address as a regular old pointer. Now, there’s nothing wrong with regular old pointers – some people have got quite a hate on for them with the rise of genuinely smart pointers, but pointers are fine. Using pointers to control lifetime isn’t fine, because it’s impossibly difficult. But pointers themselves are fine. What’s not fine here is the “decay” of an array into a pointer – folks from other languages don’t expect that at all, and some marvelous bugs have hidden behind this simple bit of helpfulness from the compiler. So there’s a guideline that says don’t do that. Specifically:

(I’m giving you a picture of code because if you want to copy and paste you should go to the live, always updated, guidelines on github.)

This guideline is part of a “profile” – a particular set of rules that are designed to be enforced and that are supported by tools. Well, when I say tools I might be overstating the case a little. There’s just one tool at the moment, but that could be enough!

This tool, C++ Core Checker, is on the NuGet Gallery. You don’t have to get it from there though. You get it, and use it, from inside Visual Studio 2015. Any version will do. If you don’t use Visual Studio normally, just get and install the Community Edition, which is free and is ok to use for commercial purposes, from https://www.visualstudio.com/ . (Need the fine print? if you’re using it as a person, you can do whatever you like. If you work for a company with less than 250 PCs and less than a million dollars US in revenue, again you and up to 4 of your coworkers can use it for whatever you like. If you work for an “enterprise” company then any and all of the employees can still use it for learning purposes or to work on open source.) Note that Visual C++ isn’t part of the Typical install, so you’ll need to choose Custom and select Visual C++:

So once you have Community Edition or some edition of Visual Studio, make a console application and put in the two bad lines of code. Build it and then also run static analysis on it (On the Analyze menu, choose Run Code Analysis, On Solution.) You won’t get any warnings or errors. That’s your pre-guidelines life. You’re doing something inappropriate and nobody is telling you.

Now, add the checker to your solution. This is solution-by-solution, not a change to how Visual Studio does static analysis. On the Tools menu, choose NuGet Package Manager, Package Manager Console. In the console window that appears, type Install-Package Microsoft.CppCoreCheck and press enter. You will see output like this:

Attempting to gather dependencies information for package 'Microsoft.CppCoreCheck.14.0.23107.2' with respect to project 'ConsoleApplication1', targeting 'native,Version=v0.0'

This changes your project settings so that analysis runs this Core Checker for you. Repeat the analysis step and this time the new tool will run and you will get output like this:
------ Rebuild All started: Project: ConsoleApplication1, Configuration: Debug Win32 ------
  stdafx.cpp
  ConsoleApplication1.cpp
  ConsoleApplication1.vcxproj -> c:\users\kate\documents\visual studio 2015\Projects\ConsoleApplication1\Debug\ConsoleApplication1.exe

========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========

Where it says "type.5" and there's a link, that's to the specific rule in the "type" profile that this code breaks. And where it says "bounds.3", the same - I showed a picture of bounds.3 up above.

Isn’t that great? Come on, it’s great! The tool will add more rules as we move through 2016. I’m going to have a lot more to say about the Guidelines as well. But this is a great place to start.Why not point it at some of your own code and see what happens?

First, have a schedule. Weeks before the conference, mark out what talks you want to attend. Have a goal of selecting two talks in most time slots. Then if your first choice is not as good as you expected, or the room is full and you don’t want to stand, you know exactly where to go for your second choice. Have that schedule in your pocket – on your phone, or on a piece of paper – so you have no lost time figuring out where to go. (CppCon uses Sched, which mails you each day's schedule in the morning, making it easy to have with you.) Don’t be the person who shows up at 9 only to learn there were sessions at 8. Check the schedule at least once a day during the conference in case things are being added. Tip: things are being added, you can count on it.

Second, plan ahead to take care of the physical body that is carrying your brain from session to session. It’s really a simple matter to have a few granola bars and a bottle of water in your bag. If you miss a snack, you can still have something to eat or drink. Bring a light sweater in case you are in the cold room. Bring some painkillers if you might get a headache from sitting somewhere loud. Bring whatever little comforts you need to keep yourself from getting whiny and leaving early to go to your peaceful hotel room and watch TV. (That said, there’s always one day in a one-week conference where I go back to my room for an afternoon nap. It’s the only way I can stay functional during long and intellectually-intense days. Just make sure you’re doing it for a brain recharge and not for something you could have avoided by bringing a small item with you to the conference centre.)

Third, think about how you’re going to take notes. A paper notebook? Bring a spare pen, too. Your phone? Your laptop? Or are you just going to immerse yourself in the experience and use the videos if you want to check something later? Whatever your plan is, bring what you need to be able to use it. Power is always a challenge at conferences – I like to bring an external battery for my phone so it can charge in my bag. Think about what your bag is going to weigh and consider leaving the laptop at the hotel and getting by with a phone and some paper for notes. It’s really liberating not to be lugging a heavy bag, in fact surprisingly so.

Fourth, before you arrive (at the latest, on the plane to the conference) write up your goals for the conference. Do you want to meet people? Specific people, or some number of people, or people from a particular industry? Do you want to learn something specific? (Perhaps this is the year to understand SFINAE, or be able to follow along in a talk that includes template meta programming, or “get” those Haskell jokes people are always telling.)  Maybe you want to tell people about something? Tweet some number of times? Blog some number of times?  Have a plan. Have goals. Check yourself against these goals each morning, and adjust your plan for the day if you need to, so that you move towards those goals each day.

When you arrive at the conference, scout out the amenities. Where are the bathrooms? Are there tables and chairs? Are there tables and chairs with power? On Day 1, pay close attention to the food and drink pattern. Is coffee always available, or only at certain times? Where does the food appear? Knowing this will take away any worry you may be carrying around that you may miss something and not get another chance at it. It will also save you from taking extras of things and lugging them around all day when you don’t really need them. I also like to work out patterns related to what rooms I’ll be in – that I’ll be on the same floor all afternoon, for example. It just makes me feel a little more settled and centred.

Looking after your body doesn’t stop with what you planned and what you brought. I start each day with 5 minutes of stretching which makes a big difference to how I feel all day. I also try to use the stairs instead of the escalators – less lining up and it makes me feel better too. I go ahead and eat the snacks, many of which are not part of my normal day (brownies in the afternoon? bag of chips at lunch?) but not to excess. CppCon has fruit and other options that are not all about fat, sugar, and caffeine, and it’s often a smart choice to go with those rather than the straight-up treats. Try not to get too far from normal. If you normally have 5 cups of coffee a day, then you can do that during the conference, but if you’re a one-cup-a-day person, perhaps don’t go beyond 2 or 3 a day while you’re here. Same advice for alcohol – if you dramatically increase your consumption over the course of the week, you’re likely to feel uncomfortable by the time Thursday or Friday rolls around. The one thing you should be sure to take in more of than usual is water – whether you’re eating more sugar than usual, drinking more caffeine and alcohol than usual, or just walking a lot more than usual from room to room in a conference centre, extra water is what you need to compensate. If you grab a bottle of water at a snack break, hang on to it when it’s empty – typically most conference rooms have a watercooler or bubbler by the door where you can refill that bottle whenever you want. Can’t stand water? Bring something to flavour it with – pick up some powders or drops at home and try them out to see which one you like. It’s way more efficient than hanging around hoping that this is the break they have juice at, or leaving the conference centre on a half hour walk for a convenience store.

As the conference goes on, be aware of how you are spending your time. For example, if you check your email during a session, but then take a peek at Twitter, and then at your personal Facebook – are you even really in the session anymore? Don’t be afraid to leave if this is not the session for you. You can go to another one, or talk to other attendees out in the hall, or go back to the hotel for a one hour nap. Almost anything is better than ignoring a speaker and killing time on your laptop or phone. And if you’re not prepared to leave, then perhaps you just need to start paying more attention to the session – assuming it’s material you actually are interested in. Take a look at those goals you wrote. Have you tweeted recently? Blogged? Learned that thing? Met enough people? Will staying in this session and listening meet your goals, or should you go out to the hall and work on a goal? Are you just chatting with your own coworkers, or someone you’ve known for years? Building and strengthening relationships is great, of course. That doesn’t mean that discussing the football game with your cubicle-mate is a good use of your time at a place you flew 5 hours to attend. Maybe you can walk around and find a way to join a conversation with a speaker or someone else you wouldn’t normally meet. Just standing there listening can be very enlightening even if you don’t end up saying much.

If you’re not normally a tweeter, blogger, or talker-to-strangers, a conference is a great place to start. There are immediate benefits. Perhaps your question will be answered, or your point will be repeated and quoted, or you’ll make a new friend or business connection. This will give you reinforcement for doing that, of course. As you meet your goals, make a record of that, so you can easily answer questions about what you learned or accomplished during the conference. Consider writing a summary when you’re done – for yourself, or for whoever funded the trip. A chronological structure is natural – Monday morning I went to a talk called X and learned Y or met Z, at lunch Monday I talked to A and B who encouraged me to look into C, Monday afternoon I went to a talk on C – but be sure to have an executive summary that reads a little less like a diary. Start writing it during the conference and polish it on the trip home. Once you get back to the office, writing that summary is going to get harder and harder, so don’t put it off.

Attending conferences is a great way to boost your career – when you do it well you learn a lot in a short time, meet luminaries of your industry and people just like you, raise your profile and your confidence, and have a wonderful time. When you do it poorly, you get tired, hungover, lonely, overwhelmed, and bored. Put in the effort to plan and prepare, and you will be in a great position to reap the rewards.
