Tech Tock

Time is of the essence.

New Year @Lab

A Junior Partner Has Arrived

New Year @Lab

I came in to 2 new projects and things are starting to pick up again @Lab.

Everyone said their happy new years and how was your vaca.  The sound of recruiting made a pleasant reprise.

Lots of folks are ending old projects and starting new projects.  Looks like all the new projects are in our favorite technologies.  Great stuff is happening – its in the air.

Back to School

The financial fundamentals training class starting next week is going to turn into a real party.  Around 20 people might be there, newcomers and old timers as well.  I’m really looking forward to it.

Desktop Esspresso

The coffee box reminds me of a chess set and the whole thing is very elegant.  Stop by for a demonstration – video coming soon!

Docking Windows In WPF

While some are of the opinion that MDI is dead and should stay that way, we did get plenty of good recommendations for docking windows for a new demo we’re building:

People recommended Infragistics. There’s a live XBAP demo here.

DevExpress DxDocking was reviewed – its a lot like Visual Studio docking.  I bet a lot of people are looking for that.

The Lab has even created some of its own specialized docking windows in the  QuickSilver Demo.

Entity Framework 2 – Almost here

I haven’t seen it yet, but this video was recommended “for a very fast but thorough tour of the new features” with this caveat:

I would bear in mind that some of the most important new features that are still slated for VS2010, including self-tracking entities, are not in the Beta 2 and available only as a separate "feature preview" download.

Muscle Control

image The picture in this article looks a little heroin freaky to me.  I’ll pass.  One gamer @Lab is eagerly awaiting the first real product.

 

Wii Dangers

Seems we all have Wiinjury stories.  The controllers fly through the air like missiles.  Muscle strains and soreness. Black eyes and broken coffee tables.  Cool game.

@Lab Competition Coming

Word has it that an official newsletter is coming – stay tuned.

@Lab This Week 11/27

Just Test – Nuff Said? Nah.

Big discussion about unit testing.  Views ranged from 100% coverage is necessary, to some code is not worth the trouble.  The 100% camp was hit with this rebuttal:

How is the coverage measured?
Is it just checking which code blocks ran during the test?
What about covering different code paths?

Everyone was in favor and there were some interesting insights including an example of “correctness by construction” in Haskell:

…”correctness by construction” (aka “making illegal states unrepresentable”).  This approach relies on a rich type-system (and, at a deeper level, an interesting fact technically known as the “Curry-Howard isomorphism”).  Ideally, when this can be achieved you can completely discharge the need for a lot of unit tests (replacing sort of probabilistic certainty with actual certainty).

Plenty of good links were sent and summarized:

This study found bug reductions of 40-90% with 15-25% coding time added.

Some recommend testability above clarity.

Guidelines on proper coding for testability (in Java).

Miscellany

I heard some talk about an A team being formed to take on a project. I’d like to see the problem these guys can’t solve.

Check out this interesting tool for translating a data model into a class model with proper naming and casing using either Entity Framework or Linq2SQL.

All in all, a quiet week as expected.

Coming Soon Entity Framework Won’t Suck

I hear that EF in .Net 4.0 will be a bit better.  An experienced developer says:

A lot of the biggest issues I’ve had with EF … have been addressed in one way or another in the v2 that comes out with .NET 4.  Self-tracking entities, POCO objects as entities, persistence ignorance, etc. etc.  I don’t know how much they’ve improved the designer.  The v2 looks much, much better.  Generally, if you don’t see moving to .NET 4 in the medium term as likely, I would look seriously into nHibernate, but if .NET 4 is realistic, I would seriously consider EF v2.

In Memory of Linq2SQL – 2006 – 2008 – RIP

I was doing a lot of Linq2SQL recently and it was easy and convenient – I’d highly recommend it. Except for the fact that its now obsolete. Linq2SQL is being tossed aside in favor of Entity Framework, which is not as lightweight or simple :(. I would look into NHibernate from what I’ve read of Entity Framework.

In another version or two Entity Framework may get more of Linq2SQL’s simplicity and ease of use. Oh joy.
