Set php.ini values using .htaccess

Unknown | 2011-09-10

Did you know that you can set php.ini values right inside the .htaccess file? You can do so by adding lines like these: #format php_value setting_name setting_value #example php_value upload_max_filesize 128M

GCC stray X in program

Unknown | 2011-09-10

Problem: IEMGD_HEAD_Linux/common/drm/emgd/display/pi/cmn/pi.c:1: error: stray ‘\357’ in program This is caused by “invalid” characters in the code, specifically I encountered this while trying to compile the Intel EMGD driver for my EEEPC’s graphics card. Thanks to the helpful folks over here, there’s a solution: cd IEMGD_HEAD_Linux/common/drm/emgd/display/pi/cmn cat -v pi.c | awk ‘{if(NR>1) print $0}’ > tmp […]

Tell your friends how to burn ISO files properly

Unknown | 2011-09-06

I have no idea how many blank CD’s I’ve seen wasted on having a file system with a single .iso file on them. Then, I found this page: http://iso.snoekonline.com/iso.htm It tells you how to burn an image with basically any Windows-based software out there. If someone runs Linux, I assume they can figure it out […]

bash time limit on commands

Unknown | 2011-09-01

Several programs, like “timelimit” and “timeout”, exist to prevent a process from running for too long. However, if you want to do this on a box where neither is installed, there’s a way to do so with bash alone. Based on the original script I found at pixelbeat.org… #!/bin/sh # Execute a command with a […]

Debian APT Pinning properly explained

Unknown | 2011-08-26

Accidentally stumbled across the “Debian Cheat Sheet” at http://carlo17.home.xs4all.nl/howto/debian.html (now dead – see pdf below) Finally some documentation on why the heck pinning with “Package: *” and “Package: mypackage” doesn’t mix well, and other useful knowledge. In case the link goes dead, here’s a PDF: debian_cheat_sheet.pdf

Using LD_PRELOAD to override a function

Unknown | 2011-07-15

This was blatantly stolen from technovelty, kept here because I hate it when my bookmarks die. For some reason, people seem to get this quite wrong a lot of the time. Certainly one should not be playing with symbols that start with __ unless you really know what you’re doing with them. ianw@lime:~/tmp/override$ cat override.c […]

How difficult is it to misuse the code you write?

Unknown | 2011-07-15

I found these “misuse levels” over at technovelty, which they originally ripped from Rusty Russel’s Bleeding Edge Page, which is a page you should definitely check out if you haven’t. Anyway, I found these “misuse levels” both hilarious to read and at the same time somewhat concerning, as I started thinking “Where does my code […]

Debian and Ubuntu auto-login and Xorg without a display manager

Unknown | 2011-07-15

If you have a harddrive password (most laptops do this) or full disk encryption, you might not feel the need for an additional login after your system boots. On most Debian-based systems, TTY’s 1 through 6 are available after boot, while TTY 7 is used for Xorg. Therefore, I like to put my auto-login TTY […]
