Eileen Rumwell is sponsoring a contest to send someone to Globewomen's annual conference, Global Summit of Women, in Berlin in June. Globewomen invite you to:
- Join the premier gathering of women leaders focused on advancing women's economic opportunities globally
- Be inspired by the energy, enthusiasm and expertise of the women decision-makers in business and government from around the world
- Learn practical strategies to grow your career or your business
- Share winning solutions and strategies with your peers
- Be part of a global network of economic dynamos who will make changes in the 21st century global economy.
A 250 word essay about why you chose the technical field you did, and how you feel about it (man! 250 words is hardly anything! that's a challenge!) could get you airfare and accomodations so you can attend this seriously high-level get together. If you don't (or can't) win, consider attending anyway ... it sounds like fun!

I missed this article when it first appeared. Mary Jo Foley talked to Jason McConnell, me, and David Johnson about getting to all the new exciting Vista goodies, and how it's a bit easier from C++ because you can mix and match native and managed so simply. Watch for more guidance and guidelines on this from Microsoft coming soon.

Dylan Smith writes about testing: Unit tests (automated, written by programmers, repeatable), Acceptance tests (stories or scripts that can be done by developers or users and test high level requirements) and Exploratory tests (noodling around by a clever person to see how an app is doing). I like these categories and I do all three on my projects. I think a lot of developers get excited (rightly) about Unit tests and run the risk of forgetting the other two. You still need to lead your users through a structured process that causes them to conclude you have finished their project. (And you still need to rehearse that structured process yourself so you know in advance it will pass.) You still need to play around with it a bit, outside of the confines of test cases, and assure yourself it really is a good application.
We're not TDD, so I don't write the tests and code to them. But I write the scripts for Acceptance testing as we develop stories and requirements. They're also a fine way to bring a new programmer up to speed on a project by leading them through what it does and how you know it's working.

These are nice ... posters of all the Visual Studio keyboard shortcuts (language specific, according to your Visual Studio settings) are now available. Here's a snip of the C++ colour one (there's a black and white one too.)
Go get it!

This year I will be partnering with my friend Tim Huckaby to deliver a pre-conference session at Tech Ed USA 2007 in Orlando:
PRCN12 From Design to Deployment: Everything You Need to Know to Optimize Your Applications for Windows Vista
Kate Gregory and Tim Huckaby
Windows Vista is the most compelling operating system release in nearly a decade. With major improvements in the areas of security, user experience, and performance, Windows Vista offers a robust and dependable platform for building a breadth of solutions. This full day seminar prepares you for building a new class of applications that take advantage of these improvements. Come and see how to take advantage of some of the most interesting new native APIs, inter-op techniques, and .NET Framework 3.0 technologies.
In this all-day pre-conference seminar, learn how to build the next generation of smart client applications with the Windows Presentation Foundation (WPF). Learn the fundamentals of WPF and work your way through advanced topics like 3D. Learn how to build great user experiences with technologies like task-based dialogs, sidebar gadgets and customized Windows search functionality. Learn inter-operability techniques with managed wrappers and how to leverage the Vista Bridge. Dive into the best practices for upgrading existing applications, leveraging User Access Control (UAC) and techniques for virtualization. Learn how to build more reliable and secure applications with technologies like Windows Error Reporting, Next Generation Cryptography and Application Restart/Recovery. And lastly, learn how to build more connected systems with Windows Communication Foundation (WCF) and RSS platform support.
Many Tech Ed attendees come a day early to do a pre-con and jumpstart themselves to be ready for the rest of the conference. Registration is open and the early bird discount is still in effect.
Other RDs delivering pre-cons include Scott Hanselman, Richard Hundhausen, and Kimberly Tripp along with many other people you have heard of. This is great opportunity to get up to speed on a topic very quickly. You can then go and drill further into some niche of it that interested you, by attending breakouts on that subtopic.
See you there!
ps: do I have a breakout session? There's no announcement on that yet

It's easy to get intimidated by a feature like Lambda Expressions. It has a Greek word in it, so it must be difficult, right? And you can read explanations like this:
Lambda expressions, one of the most important new features to be included in the next 3.0 version of C# and one that offers support needed by the LINQ Project, are precisely a feature coming from the world of functional programming. ... Scheme ... Lisp ...
Or this summary:
In mathematical logic and computer science, lambda calculus, also λ-calculus, is a formal system designed to investigate function definition, function application, and recursion. It was introduced by Alonzo Church and Stephen Cole Kleene in the 1930s; Church used lambda calculus in 1936 to give a negative answer to the Entscheidungsproblem. Lambda calculus can be used to define what a computable function is. The question of whether two lambda calculus expressions are equivalent cannot be solved by a general algorithm. This was the first question, even before the halting problem, for which undecidability could be proved. Lambda calculus has greatly influenced functional programming languages, such as Lisp, ML and Haskell.
Lambda calculus can be called the smallest universal programming language. It consists of a single transformation rule (variable substitution) and a single function definition scheme. Lambda calculus is universal in the sense that any computable function can be expressed and evaluated using this formalism. It is thus equivalent to the Turing machine formalism. However, lambda calculus emphasizes the use of transformation rules, and does not care about the actual machine implementing them. It is an approach more related to software than to hardware.
This sounds really difficult. So let me show you something that's not difficult at all:
<INPUT TYPE="radio" VALUE="Switching to Blue" onClick="alert(value);document.bgColor='blue'">
It's not actually that intimidating at all ... it's going to make life easier.

[Sorry about the blogging gap - nothing dramatic, just a little case of overworked and underslept. Good excuse to start up again though.]
Imagine a room with a table, no computers, and four really smart people who care tremendously about helping people write software, and who tackle questions like "what keywords should be in this language" every day -- and whose decisions actually will get implemented. A full hour of amazing conversation appeared recently on Channel 9.
How will imperative programming languages evolve to suit the needs of developers in the age of Concurrency and Composability? What role can programming languages play in enabling true composability? What are the implications of LINQ on the furture of managed (CLS-based) and unmanaged(C++) languages? How will our imperative languages (static) become more functional (dynamic) in nature while preserving their static "experience" for developers?
Answers to these questions and much more are to be found in this interview with some of Microsoft's leading language designers and programming thought leaders: Anders Hejlsberg, Technical Fellow and Chief Architect of C#, Herb Sutter, Architect in the C++ language design group, Erik Meijer, Architect in both VB.Net and C# language design and programming language guru, and Brian Beckman, physicist and programming language architect working on VB.Net.
This is a great conversation with some of the industry's most influential programming language designers. Tune in. You may be surprised by what you learn...
Some quotes and paraphrases that caught my attention:
- "No language can ignore concurrency and stay successful for mainstream programming over the next five, ten years."
- our entire industry is based on composable software and we manage to do composable software with the languages, libraries and frameworks we have now. it's rather amazing that we can do it.
- "all you can do as a language designer is slow down the accrual of new features that will eventually lead to cave in."
Now if you aren't sure you know what a lambda expression is, or what makes a language functional as opposed to imperative, or what LINQ would have to do with that, or what composability is, then you may think you don't want to watch this video. But you'd be wrong! Spend this hour with these gentlemen and not only will you learn all those things, you'll learn why it affects you and why you should be following, at least a little bit, the current work in this area.

A lot of people are asking me if I am using Vista, if they should use Vista, if I think Vista will get good adoption, and so on. I have Vista on some machines, still have XP on my ancient primary laptop, and miss Vista when I'm not using it. I tell people this and they assume it's all about the shiny and the seethrough and the pretty. It's really not. For me the fast search is a big thing. And I still consider UAC a feature and have no intention of turning it off or launching everything I do from an elevated command prompt. I like the thumbnails that actually show your content - though I suppose some might dismiss that as "pretty", it's saved me from opening big files with odd names more than once, just so I can tell whether I want to delete them or not. An MSDN article lists a number of useful benefits of running on Vista that have nothing to do with being pretty. Beyond UAC and other security benefits, consider Sleep (fast as Standby, safe as Hibernate), SuperFetch, ReadyBoost, restart manager, presentation mode, ... there's so much! It's not just about the .NET Framework 3.0 -- you can have that downlevel. It really is a new version of the operating system and it does a lot of things a lot better.
So I forgive it for being pretty.

I once had an opportunity to write one of those Teach Yourself <Something complicated> in 21 Days books, or it might have been 24 Hours, or A Weekend, I forget. I was overloaded with work at the time and didn't write it. One of the things about writing those books is that nobody actually expects the reader to learn what they need in 21 days or 24 hours or whatever. It's basically the number of chapters. And if you processed one chapter a day, I guess you would cover the book in three weeks, but you wouldn't be a <Something complicated> programmer at the end of that, would you? Some folks might do 5 chapters a day, others might do a chapter a week. It depends on where you're starting from.
I came across a few interesting blog posts on this topic. Peter Norvig found hundreds of such books on programming languages or frameworks, and proposes instead Teach Yourself Programming in Ten Years. He has a point. Jasmine refines the point a bit, saying that if you're already a good developer you probably can pick up a new language or framework in a matter of days, and that if you don't have what it takes to be a good developer, ten years of plugging away at it won't make you good enough.
I've been getting paid to program since 1979, and I learn new things all the time. But I try to learn new languages no more than once a year -- and I wouldn't be able to invest 21 days in learning a language, either. More importantly, I've invested quite a lot of time and effort into spotting those who will be good developers some day, and trying to speed the process of making them better. I think the emphasis on debugging and on reading or fixing the code of others is appropriate. It's tempting to have the newbies work on little projects alone since they can't understand your big complicated project with difficult code written by the really smart people. But trying to understand that project and that code is what will make that newbie a developer -- or show you both that it's a hopeless cause .
