Examining PDB files with DBH
Wow, it’s been a ridiculously long time since I’ve blogged. I think it’s time I put something up just to break the curse, and this seemed like a good, and hopefully useful, place to start. Time to polish some of these dusty drafts into published gems.
Ever been in that situation where you (or someone else) finds that Visual Studio just won’t set a breakpoint in some source code that you’re sure should be being used? You’ll see the hollow breakpoint icon and something like ‘The breakpoint will not currently be hit. No symbols have been loaded for this document’.

Beginning F#: Records
In the second of an unknown number of parts in my series of Beginning F# posts, I’ll be talking about record types. They’re a useful and powerful F# feature that you’ll probably find yourself using very widely. I’ll take a look at what they are, how they’re used and how they integrate with the rest of the language.

.NET DLLs Loaded Twice
If, like me, you’re still squeezing yourself into 32-bit Windows processes, you’re probably, also like me, constantly keeping an eye on the virtual address space usage of your application.

30 years ago at CES…
The other day while I was looking through some of my ancient copies of Computer and Video Games magazine (“the first fun computer magazine!”) I discovered some coverage of the 1982 Consumer Electronics Show. It’s such a contrast to today’s shiny, immaculately produced, PR-fest that I couldn’t help but scan it in for everyone to see.

Tax Avoidance 2.0
Warning: This is a bit off-topic for my blog, but I had to write it and get it off my chest.
In these times of financial woe, people love to complain about all the big, nasty, faceless companies avoiding paying tax. They inevitably moan about it on Facebook, Google and Twitter (and sometimes even do something about it in the real, physical, world). But what about those companies themselves? The Web 2.0 behemoths are now some of the largest companies in the world, and they’ve decided – just like the evil old companies – that they don’t like paying all that tax. Don’t be evil… and don’t pay any tax if you can help it. But how do they do it?

Looking back at 2011
Well, we’re a few days into 2012 and no armageddon yet, so it’s probably safe to take a quick glance back over our shoulder at some of the technical stuff that’s flashed past in the preceding 12 months.

Creating a physics-based OpenGL iOS app
With the success of iOS games like Angry Birds and its flocks of imitators, there are lots of people looking at creating physics-based games, so I decided to try and create a simple demo using OpenGL ES and the Bullet physics engine.
