sudo apt-get install ncurses-term

Install sun-java6-jdk on Ubuntu 10.04 (Lucid)
Sometimes installing Java can be as if someone stabs you hundreds of pencils in the ass. I had trouble to install the Sun Java6 JDK after updating to Ubuntu 10.04.
Installing Post-Commit-Hook for Subversion and Trac 0.11
If you have a Subversion running including a Trac connection, it’s nice to have the post-commit-hook running, too.
With this hook, you can include additional keywords (closes, fixes) in commit-comments which then allow to close, fix etc. tickets.
I installed it in the following way.
My Subversion directory is in this case /svn and my Trac directory is /trac.
mkdir -p /usr/share/trac/contrib cd /usr/share/trac/contrib wget http://trac-hacks.org/export/7848/timingandestimationplugin/branches/trac0.11/scripts/trac-post-commit.py
Now the SVN settings
cd /svn/hooks vim post-commit
Add this content to the post-commit file (via http://trac-hacks.org/wiki/TimingAndEstimationSVNPostCommitHook):
#!/bin/sh REPOS="$1" REV="$2" LOG=`svnlook log -r $REV $REPOS` AUTHOR=`svnlook author -r $REV $REPOS` TRAC_ENV='/trac' /usr/bin/python /usr/share/trac/contrib/trac-post-commit.py \ -p "$TRAC_ENV" \ -r "$REV" \ -u "$AUTHOR" \ -m "$LOG"
Change some privileges and owner-ships:
chown www-data:www-data post-commit chmod 755 post-commit

The following signatures couldn’t be verified because the public key is not available
I wanted to update my Debian packages via

and what I got was the following error:

if you are already root.

I got the following error when trying to create a ssl-certificate on Ubuntu 8.04:
apache2-ssl-certificate: command not found

manual of the day… install Erlang and Mochiweb under Ubuntu
install Erlang and Mochiweb under Ubuntu
First of all we install necessary components and start with the Erlang installation:
sudo apt-get build-dep erlang
sudo apt-get install java-gcj-compat java-gcj-compat-dev
Then we download the source of Erlang (newest versions are available here: http://erlang.org/download.html). I took the R12B-5 release.
wget http://erlang.org/download/otp_src_R12B-5.tar.gz
Extract
tar xfvz otp_src_R12B-5.tar.gz
Configure (choose your favorite directory for the Erlang installation, here: /usr/local/erlang), build and install it:
cd otp_src_R12B-5
./configure --prefix=/usr/local/erlang
sudo make
sudo make install
Now the Mochiweb part
We checkout the newest Mochiweb source using subversion (if not installed yet. Install subversion using sudo apt-get install subversion).
svn checkout http://mochiweb.googlecode.com/svn/trunk/ mochiweb
cd mochiweb
sudo make
