Logitech G15: Rubber gets sticky

Posted by on Saturday, 20 July, 2013

The Logitech G15 was a great “gamers keyboard”. I bought it years back because the screen was awesome to do some programming with. The keyboard was coated with some sort of rubber, giving it a very awesome matte finish and touch. Unfortunately, this coating does not stand the test of time too well, and it becomes sticky. Read here how to solve this. Read the rest of this entry »

Trailing comma in IEEEXplore BibTeX

Posted by on Friday, 28 September, 2012

As a frequent user of the IEEEXplore database to search for literature concerning wireless networking, I often export a citation to BibTeX for use in my papers.

One of the things which has puzzled me for a long time, is why the BibTeX exporter adds a trailing comma after the last field.

Saving power by disabling sound chip on Linux

Posted by on Monday, 10 September, 2012

For years I have been running Linux servers. Some time ago I built a NAS box running Ubuntu Server. I’ve done quite some tweaks to reduce power consumption. But there must be more. Or less, so to speak.

Google Scholar citation email verification does not work

Posted by on Friday, 3 August, 2012

Anyone who has ever done anything even remotely related to science is probably aware of Google Scholar. There’s this feature where you can keep track of your citations (e.g. how many and which papers by which authors cite your publications). A very nifty feature and quite easy to set up. Your data will only show up after your email address has been verified. And that’s where stuff borked.

The verification link did not work, giving a 404 Not Found error. After inspecting the url I noticed that the dots in my email address had been removed. I figure they probably have some scripts there like php’s
htmlspecialchars() and addslashes() to prevent such things as SQL injection, but apparently this also removes dots from the email address being verified, and then obviously the url does not coincide with what I entered, yielding 404.

Solution: simply add the dots in the url and it works.

spaces in MiXiM makemakefiles

Posted by on Friday, 20 July, 2012

MiXiM uses a ‘makemakefiles’ script, which makes the Makefiles by means of the following command:

make -f makemakefiles

However, after some modifications (adding own stuff) it stopped making new Makefile files. From visual inspection, nothing is wrong with the file. However, there’s a subtle thing you may want to check: the TAB in front of each line. DO NOT make the mistake of adding a few spaces, this is not just there to prettify things, opp_makemake apparently delimits on this TAB and gets severely upset from spaces there.

Removing any spaces and adding a TAB fixes the problem.
