I’m happy to announce that the Grr RSS Reader application is now part of the GNUstep Application Project (GAP).

A great introduction to garbage collectors: “Storage Management, cont’d” (Paul Hilfinger). It was fun to figure out how to implement this. Just a short link, I didn’t want this to get lost in my twitter stream.

- Podcast (Get lecture 41.)
Lessons learned: My first C program with a void***. Should have used more unions. Just about 200 lines of C, a working stop-and-copy garbage collector. A fun hack, but hard to test. It’s probably buggy. 
This is a handy trick to see whether you’re in a directory managed by version control or not.
To enable this prompt, I use the following code snippet (in my .bashrc file):
pimpmyprompt() {
if test -d `pwd`/.svn ; then
pwd | sed -e "s#^$HOME/*# #" -e "s#/.*\$##"
fi
}
export PS1="\u\e[0;32m\$(pimpmyprompt)\e[m:\w$ "
Note: This will always print the name of the first path component after $HOME, which is not necessarily a SVN working copy.
Update: Also have a look at Frank’s hint in the comments, which looks quite useful for when the customizations start to grow.
Here’s a neat trick with htaccess files: The page on my diploma thesis should be available to everyone within my university subnet, and to selected people from outside, who may authenticate using usernames and passwords.
This .htaccess file seems to work for it:
AuthUserFile "/home/guenther/htpasswd" AuthName "Only visible from the TU Kaiserslautern subnet or with username (ask me for it)" AuthType Basic Satisfy any order deny,allow deny from all allow from 131.246. Require valid-user
From the outside, you’re asked for a password, from inside the subnet, you can see it without password. Works.
Ralph Johnson (Yes, from the Gang of Four) writes in “Comment on a comment on 4+1 views”:
“The book Documenting Software Architectures: Views and Beyond is a great source of ideas for different viewpoints. If you take the book literally, however, you’ll write bloated documentation. So, don’t take it literally. Use it to jog your creativity. It is the only book on software architecture documentation that I know of, hence the best.”
Yes, this sounds obvious. Too obvious to mention, you think? read more…
