Intel Wireless N Cards

I’ve had a lot of problems with the Intel wireless cards, when connecting to Wireless N Routers.

The speed cuts off, or drops to 1MB/s, you can set the rate manually by issuing the following command, replace wlan0 with the equivalent for your system, but usually it’s wlan0 unless you have multiple wireless cards.

iwconfig wlan0 rate 54M

Compile/Backport packages from source Ubuntu/Debian

I’ve run into several situations where the packages I want are not available on the distribution version I’m running.

Daily SVN Incremental Backup

Lately I’ve had a lot of repositories to deal with, so I wanted to back it up, beside doing the usual, creating a hotcopy I decided to create incremental backups of all the repositories, so we can restore them even if for some reason the hotcopy fails or the repository get’s corrupted, both of them the master and the hotcopy.

So I need to do this on windows, and on linux (ubuntu), but this should work on all the distributions of linux, provided you have the required programs installed, this is mostly for Cygwin, because usually the tools required come pre-installed on the distributions, and you also have to have installed Subversion and have it in your path.
