A friend of mine challenged me today to the number game. This is a classical one, where you have to guess a number between 0 and 999, and the computer will tell you whether you were right on or if you were above or below the chosen number.
Instead of doing dichotomy by hand or with [...]
Beware: trying to move your Jabber (XMPP) server from one host to another may result in your users not being able to reliably talk to users using Google Talk or Gmail chat. It looks like one way or the other Google caches the SRV records of your Jabber server and do not consult the DNS [...]
My LG Flatron L1915S monitor decided that it was tired of working so hard: the backlight now turns off after a fraction of second. Of course, it happened right after the warranty period expired, so it is unlikely that I can get it fixed. A fair number of users seem to have the same problem, [...]
Back in 9th grade. My science teacher was explaining to the class why carbon monoxide (CO) inhalation was dangerous: carbon monoxide molecules attach themselves to the hemoglobin, preventing dioxygen molecules (O2) to do so. The carbone monoxide doesn’t dissociate from hemoglobin under normal pressure, making it a long-term problem (ok, this was a simplification, but [...]
Am I the only one who would have loved to see a second season of Battle Programmer Shirase coming?
First I hoped I had misread the web page. Then I realized I had not.
Networked disks are very useful. At home, they allow you to access your data from any computer on your local network without needing to keep a machine acting as a file server turned on all the time. But wait! You could [...]
I was surprised to see that wget chose to use IPv4 over IPv6 when downloading a file. It looks like it is on purpose (I would call it a bad design choice). You can tell wget to prefer IPv6 over IPv4 by putting the following line
prefer-family = IPv6
in either /etc/wgetrc (system wide) or $HOME/.wgetrc (user [...]
Since about a week, I started to notice that I had been making a lot of typos in some commands I use frequently. For example, I became unable to type correctly
cd /usr/src/linux
which always resulted in
cd /usr/src:linux
(incidentally, when typing the above strings, I had to fix the first one and the second one came naturally buggy)
On [...]
Tonight, I was willing to create a while construct in Factor taking two items on the stack:
a quotation to execute when the test is true
a test quotation
For example, I wanted to be able to find the smallest power of two greater than or equal to an arbitrary number (here 34098) by doing:
1 [ 2 * [...]

Do you want to come study for one year in Paris for free in the prestigious École Nationale Supérieure des Télécommunications? We teach computer science, electronics, embedded systems, robotics, optical communications and many other things.
If you answered yes to all those [...]
