So, I have 5 mins for telling about our vacation. We was in Bulgaria ski place. It names Bansko

questions from a M$ interview

Thx for my friend))) I think this questions from his interview for the Bing command.

id Software Consolidates Open-Source Code

It doesn't look like id Software has dropped (or otherwise revised) any new major code, but rather they have consolidated all of their open-source efforts on GitHub. Hosted from this GitHub area is now the source-code for Wolfenstein 3D for Apple iOS, DOOM Classic for iOS, the original Quake GPL, the original DOOM, Quake-Tools, idsetup, Quake-2-Tools, GtkRadient, the Doom 3 GPL release, Enemy Territory, Return to Castle Wolfenstein Multiplayer GPL, Return to Castle Wolfenstein Single-player GPL, Quake 3, and Quake III Area. Each of these titles have their own Git repository on GitHub.

Google Interview Questions

Some time back I interviewed with Google, and a number of other well known software development companies. I've written up a number of questions very similar to the ones I was asked, changing them enough so that I'm not breaking my NDA.

git server on non standard ssh port

Some time ago I think about how to connect to a git server if it's on non standard ssh port. This case can occurs when you make port forwarding with ssh inside your network (look at -L key in man ssh), or if you want to avoid scanning your hosts by dumb bots.

At first I think about .git/config file and how can I force git to ask server on another port. But next I realized that's not question about git it's the question about ssh. And solution was really simple - put a host description into ~/.ssh/config

Host myhost.xxxx
    user imauser
    Port 31337

I looked through book about writing kernel modules in Linux (actually it's in russian lang). It's oriented on x86 architecture. I fount some not so real but interesting sample with syscall from inline assmebler code and port it to arm architecture. I used codesourcery toolchain.

Some information about arm syscalls in linux. According ARM EABI one use r7 register for syscall number and swi 0 (or svc 0, codesourcery gcc generate the same code) for syscall. One can use also r0-r5 registers for 32 bit parameters (or r0...r6 for 64 bit parameters, but them must be aligned to even number of registers)
