Debian Backporting

It is easy to install packages on Debian. All you have to do is "apt-get install package". But what if we would like to install a newer version package? For example, git-core version on Debian stable is 1.4.4. It is too old and does not have basic commands such as git config, init,... etc. We may install git from Debian Backports. It is a easier way than building from source for most people.

Remove allow_branch_to_undefined from U-boot

Old U-boot (v1.1.3 in my example, too old hum?) needs a option -mips_allow_branch_to_undefined for ELDK AS to assemble. We have to modify cpu/mips/start.S so that AS of other toolchains could assemble it without an error - Error: can't resolve `_GLOBAL_OFFSET_TABLE_' {*UND* section} - `L16' {.text section}

wikipedia: inotify is a Linux Kernel subsystem that provides file system event notification. It was written by John McCutchan with help from Robert Love and later Amy Griffis to replace dnotify. It was included in the mainline kernel from release 2.6.13 (2005-06-18).

Wikimedia as a presentation application

I tried wikimedia slides extension at first. It worked fine. However, if you'd like to present on wikimedia, I recommend another interesting approach: one of the Firefox Greasemonkey scripts - Wikipedia Presentation.

I believe it would be quite easy to understand the modification, which substitutes 'issue #id' to an URL link to mantis system.
