UNIX

The purpose of a debugger is to allow you to see what is going on inside another program while it executes. It is useful to find out what another program was doing at the moment it crashed. I know most people will recommend GNU gdb, Nemiver, Valgrind or IDE such as Eclipse. I use gdb when it is really required; otherwise I debug the old fashioned way using printf() or cout statements.

This may come handy while writing cross-platform scripts.

If you don’t want to commit to the idiosyncrasies of a specific shell running on a particular platform, try the Squirrel Shell. The Squirrel Shell provides an advanced, object-oriented scripting language that works equally well on UNIX, Linux, Mac OS X, and Windows systems. Write a script once, and run it anywhere.

Squirrel is a high level imperative/OO programming language, designed to be a light-weight scripting language that fits in the size, memory bandwidth, and real-time requirements of applications like video games.

Comming soon: Wine 64 bit For 64 bit MS-Windows application
I can finally report success on the first ever win64 program running on wine. The program was a textbook classic, but to make it work gcc had to be changed a lot. This was done by Kai Tietz, who has put a lot of effort in the task of making gcc accept the calling convention.

How to sync Evolution with Google’s PIM apps
While I’m a die-hard Google user — especially the PIM apps — I still appreciate offline applications for the integration with the desktop, speed, and features they sport. The Evolution contact and calendaring application is a great example: it’s as feature-packed as Microsoft Outlook, but with GNOME integration, and it’s fast. Gmail, by comparison, is slow and lacks any desktop integration. In a perfect world, Evolution would sync with Google’s PIM apps. Unfortunately, there aren’t any good, easy-to-use, comprehensive guides for setting up Evolution to sync with all of these apps — until now.
