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!
