Here's a very brief summary of how Stack Overflow DevDays 2011 will go down:

  1. It'll be two days long.

  2. It'll be sometime in September or October.

  3. There will be FOUR independent, separate events to choose from in different cities: London, Washington DC, San Francisco, and Sydney.

  4. There will be a single track, so you never have to worry about choosing between two equally cool topics.

When we did DevDays 2009, the idea was to do some intensive, one hour programming tutorials on the kinds of topics that we thought a lot of programmers really wanted to learn, but didn't have a chance yet to use at work. Two years ago, the topics we tried to cover were jQuery, Python, iPhone development, ASP.NET MVC, Google App Engine, etc.

This year, we've got two days, so there'll be time for even more sessions. We'll also have time for deeper, more big-picture talks in between the tutorials.

What topics would you like to learn about at DevDays 2011? One topic per answer, please, and vote up all the ones you like.

UPDATE (April 21st) Thanks for all the feedback, ideas, and votes so far. Keep it coming! We are working on nailing down dates and venues. Soon, we will line up committees for each city responsible for lining up speakers and fleshing out the schedule: they'll use this input as guidance to set up an awesome program in each of the four venues.

In the meantime if you have other questions about DevDays or other discussion, please ask it as a separate question tagged devdays-2011, don't just leave a random fly-by comment in the comments.

    Any chance of some open space sessions at these events? The best parts of the last conference were the discussions between sessions and afterwards. The topics at the DC event were hit and miss. If you want info/advice on running these talk to the PyCon folks like Bruce Eckel as they run them really well, compared to those I've seen at .NET events.

    @PhilPursglove I'm not sure I'd bother going to the conference if that was the case. I can understand why DVCS is leading below, but I don't think that it necessarily makes for the best presentation or conference content. It would need to cover material above and beyond the likes of the hg init tutorial.

    @BrianLy "The topics at the DC event were hit and miss" This is likely the biggest reason they are 1) holding fewer events and 2) forming committees to determine the topics and speakers.

    @adam - the reason there are fewer events is because of the tremendous amount of time and energy it takes to do a venue/event. They are delegating the work and looking for an easier way to find/determine topics. It has nothing to do with "hit and miss"

  • I can see how examples of workflows and/or integration with other tools might be good fodder for sessions. However I've been to one too many DVCS tutorials and presentations along those lines would be boring.

  • I downvoted this. Nothing personal!!! I really like DVCS, but I've read a bit about it already, played around with Mercurial (love it!), but I don't feel like I can get my organization to swiftly remove our TFS infrastructure and replace it with Mercurial. Learning even more about DVCS wouldn't, I don't think, change my mind.
    – codes_occasionally
    Commented Apr 21, 2011 at 18:17
  • @BrianLy: nothing boring about such a session: this is very practical, and tackles authentication, authorization but also workflow and integration with existing tools/IDE. @Pandicus: true (I have the same scenario with IBM RTC Rational Team Concert). My presentation would also draw a contrast between TFS or RTC and DVCS like Git or Mercurial.

    Commented May 13, 2011 at 11:00
  • @VonC - You are better off with a consultant to address your particular needs than expecting a devdays to address those. I repeat - there are plenty of resources online to address the content in your question's text. You may have some things in mind that are not in the question - but this is not really a topic that is really that compelling. If you can't convince your team(s) of DVCS with the content already out there then a 2 hour presentation from DevDays is not going ot help either. Just because it is (still) the latest shiny thing doesn't mean it is good for devdays in general.
    – tim
    Commented May 13, 2011 at 13:46
  • @tim: this is not about convincing the team (they hardly need convincing most of the time ;) ) This is about taking into account the particular needs of a big corporation, compared to what a DVCS in general can offer. I am very much interested by those "plenty of resources online" you keep referring to, because I didn't find that many when I did my setup, migration and introduction of a DVCS in my large company.

Deployment

One of the more challenging situations we encounter (in our very small shop) is deploying new versions of software smoothly. I hear a lot about one-click deployment, build automation, and continuous integration, but I'd like to learn more.

Perhaps one or more of the following topics could be discussed:

  • Package management (OK, maybe the NuGet answer covers this)
  • Build servers/build automation
  • Configuration file/connection string management
  • One-click deployment/'Continuous Deployment'
  • Database versioning/upgrading to newer schema/downgrading to older schema

Programming Best Practices

While a lot of folks on Stack Overflow are experienced developers, I'm sure there's quite a few who are newcomers to the field and are still learning. A good topic might be an overview of some industry best practices to make the event more open to newcomers, and to perhaps give folks still in school some insights into real world problems/solutions which they might not normally learn at school.

A quick list of things that spring to mind:

  • SQL injection - What is it? Why is it bad? How to prevent it?
  • Version control - Why you should use it, systems available, single vs distributed, etc.
  • Internationalization - Unicode, why it's not as simple as it first seems, etc.
  • Encryption - Why it's bad to roll your own, etc.
  • Unit testing - Why it's important, how it helps, etc.

As the event is single track, the downside would be that it would be of little use for experienced programmers whom I imagine would make up a significant portion of the audience.

Writing a compiler or interpreter (or even plain old parsing)

This is something that a lot of people do in a CS course. For a lot of programmers who did not study CS it is scary, but interesting at the same time.

Since this is such a huge topic there are various ways it could be approached. Examples:

  • Basic howto with some working example that attendees can explore after the event.
  • Pick apart an existing compiler or interpreter like IronPython.
  • Review some common language features and how they are implemented in different compilers or runtimes.
  • Look into how a DSL can be created.
  • How to build a SQL parser with a popular language.
  • How parsing techniques can be used outside of a traditional compiler/interpreter to make life easier.

Advanced Topics in Computer Science

A survey of interesting "latest and greatest" issues that are being explored but haven't quite hit the main stream yet, or are just starting to get attention, or that are not being leveraged fully yet. For example GPU computing, multicore computing, or scientific computing clusters might be a topic.

This might not be a good area to work on for side-topics or break out sessions, but I could see at least one main topic being presented as part of the regular main sessions. Additionally, if you have a limited number of locations for travel, you might also be able to get someone from a local university to come in and give a presentation on a topic.
