  How Computers Boot Up

The previous post described motherboards and the memory map in Intel computers to set the scene for the initial phases of boot. Booting is an involved, hacky, multi-stage affair – fun stuff.

  The Balanced Developer

In preparation for a recent team offsite, I spent some time thinking about what I hold dear as a software developer. One idea I kept coming back to is the notion of balance. I see balance manifesting itself several ways in the work of a successful developer, some of which follow.Speed Versus QualityThe most obvious example is the balance of development speed and quality. When building software, it’s never a good idea to write code as fast as possible without any attention toward maintaina...

With this feature turned on, our system resources can be secured with only permitted operations. When JVM starts, it will first check whether the SecurityManager is on by checking the system property java.security.manager, if it's on, then an instance of SecurityManager will be created and it can be...

  High performance web apps with C++

It is Christmas over here, and it is time of giving. So I decided to give something back to the community. I guess this is as old as web programming itself. Trying to create C++ web framework. If you search on the web, you can find dozen of guys that had exactly the same idea. I am not different. For one of the previous projects(discontinued now) I created simple web framework in C++. If you like to hack in C++, here it is. Code is provided as-is, as part of larger application. You can ex...
