Kernel progress

Ok so I;m back at work and that means two things, my day is pretty full up with my day job, which is fine/cool ‘cos I like doing AppV stuff. Just need to re-focus a bit so my work on the kernel has slowed down. That said on the bus last night and this morning. I read up on the VFS abstraction interface provided by the kernel. Mostly learned about the superblock ,inodes and dentries.

Its that period after Christmas and just before new years that everyone has taken off, so it pretty quite in the office. That's actually pretty cool because a) no ones asking me questions and b) its quite and c) I can turn my music way up. I mean at times the lights just go off and I’m sitting in front of my monitor and I have to occasionally do a ninja kick move to re-activate the motion sensors to get the lights to go back on.

I’ve been working on synchronisation issues in my work code recently. Which is interesting because I’ve just covered Synchronization in the kernel book I’m reading. But, I’m not getting it right. If I put the task on the ThreadPool(Windows) and then run the operations within the ThreadPool in parallel themselves – stuffs goes kaboom. Its OK – this period is not that stressful I’m not on a deadline which is good because I’ve been not getting this right for 2 days now.(edit: I’m got it working! Nothing like a big fat lock can’t help..remember lock data not code.)

While C is a cool language that has a special place in my heart – C# is also pretty great. I’ve been reading Stroustraps’s Tour of C++ but its pretty dry and things like Lambdas in C++ 11 are encouraging me to have a look – could C# give way to C++ (for me, probably not).
