I had a difficult time figuring out how to make some complex routing / firewall set up at my previous job, and I learned a few things.

I made an article at with all I learned, summarizing all I could find by reading dozens of different documentation... Information is very fragmented, I tried to get them all together in this article.

The article is in an open wiki, contributions are welcome.

I didn't even knew one can extract information from memory modules, until I discovered this can be done even under Linux ;-)

I made an article at teaching how to read your memory information from within a Linux box.

Now you can know who is the real manufacturer of those "generic" memories you find on the market...

I am trying to find a way to let my notebook's HD spin down to save battery, however something still uses it constantly and I can not find what it is.

I recently used Windows Vista and it has a very nice feacure: a top like disk access statistics. I can easily identify what process is using the disk and at what rate. I could manage to easily solve some performance issues on Vista using this tool.

The question is: is there a way Linux kernel export disk access usage per process? All I have seen until now is a system wide value, for a whole block device...

There is the brute force method of course, lsof + find by latest modification / access date... but that's not exactly what I want.

Ah, I know about laptop mode, but I wish to fix the cause of the problem (no more useless disk access).

I had a difficult time finding just a few lines of configuration to make my Debian notebook connect to the internet using my phone's bluetooth and GPRS.
I ended with a working solution in case someone needs to connect a Linux system via a GSM modem. Have fun.
