As noted from my previous blog post regarding Mapserver on Debian, you don’t get AGG with Mapserver when installing directly from Debian packages. Thus, it would be better to install Mapserver by source. However, debian still helps because it would install all the necessary libraries needed for compiling mapserver. Read more…
I read somewhere that Firefox was renamed to Iceweasel on Debian. Thus, I can’t install the Google Toolbar for it. So here are the steps for installing Firefox manually in a linux system. Read more…
If you need to setup/install Debian. Please follow this post.
1. Removing a service from startup
# update-rc.d -f samba remove
2. Installing a service on boot
update-rc.d myServiceName start 80 2 3 4 5 . stop 15 0 1 6
3. Specifying Debian Sources
#vim /etc/apt/sources.list
#SID:
deb http://debian.cn99.com/debian unstable main
deb-src http://debian.cn99.com/debian unstable main
#LENNY:
#deb http://debian.cn99.com/debian testing main
#deb-src http://debian.cn99.com/debian testing main
#ETCH
#deb http://debian.cn99.com/debian etch main
#deb-src http://debian.cn99.com/debian etch main
4. Searching for a package from the repository
apt-cache search [package name]
5. Installing a package
apt-get install [package name]
6. Purging an installed/configured package
aptitude purge [package name]
7. Upgrade a debian distro
apt-get dist-upgrade
I was greeted with “No space left on device” on my cron log. Turns out that my svn server obviously ran out of disk space. The old svn server was running on CentOS4.3, Subversion 1.3.2, Trac-0.11.devxxx. I decided to migrate the svn data to a new server, so I installed Debian4.01 on a small server with 72 GB HD, no partitions (just / and swap, so the svn have room to grow…). Here are the steps I took for the migration:
A. A fresh start…
1. Installed Debian. Fixed network and ssh.
2. apt-get install apache2
3. apt-get install subversion
4. apt-get install python python-setuptools python-mysqldb python-subversion
5. apt-get install libapache2-svn libapache2-mod-python
B. Making SVN work…
1. svnadmin create /repos –fs-type fsfs
2. Since I have a fresh apache configuration, I edited it accordingly from /etc/apache2/mods-available/dav_svn.conf:
#SVN dir <location> DAV svn SVNPath /repos SVNAutoversioning on AuthType Basic AuthName "SVN - Your Project" AuthUserFile /repos/svn-auth-file Require valid-user </location>
3. Restart apache
4. To test if svn is running, import a project inside the repository.
svn import -m "initial import" /tmp/project http://127.0.0.1/repos/project
C. Migrating the data
After I got my fresh debian svn machine, I need to move the svn data and trac to the new server. http://svnbook.red-bean.com/nightly/en/svn.reposadmin.html
1. Transfer /repos/svn-auth-file and /repos/svn-authorization-file to the new server
2. Transferred trac.tar.gz (/var/www/trac) to the new server
To move the svn data from one server to another, I tried the ff choices…
1. svnadmin dump /repos /reposbak. Will work if disk space is not an issue. My /repos is 25 GB, and my other 30 GB partition was wiped out, even though the dump was not finished yet.
2. svnadmin hotcopy --clean-logs /repos /repos2. Accdg to the docs, this is exactly the same repository without the BdB logs. I then transferred the hotcopy from choice 2 above to the new server and works flawlessly to my surprise. So now, I still have all my revisions

‘R’ is a statistical package. For an overview, please go to www.r-project.org
My intention was to remove the point outliers from a given set of point geometries.
I just recently installed R both on my Windows XP and Debian. Regina’s www.bostongis.com is an excellent tutorial in getting involved with R. I do suggest you head first to PLR Part 1: Up and Running with PL/R (PLR) in PostgreSQL: An almost Idiot’s Guide to get you started.
The install instructions for Windows works flawlessly. I have to hold back to R-2.5 though as I plan to use RPy (Python for R), see details below. To install ‘R’ in Debian, there’s a couple of settings that we need to take care of…
1. Install r-base
sudo apt-get install r-base
2. Install plr on postgres
sudo apt-get install postgresql-8.2-plr
3. Using R in a database
psql -d beijing -U lbs -h 127.0.0.1 < /usr/share/postgresql/8.2/plr.sql
4. Set the R_HOME environment variable
/etc/postgresql/8.2/main/environment
R_HOME='/usr/lib/R'
5. Restart Debian.
RPy, R for Python, is another alternative to use R in Python. I installed it both in Windows and Debian. Note that I reverted to R-2.5 on Windows to be compatible with RPy. For Debian, Im currently using R-2.6.
For the Windows Binary Installation,
1. Read the RPy Main Site
2. Install prerequisites:
- NumPy
- Win32 Extensions Download
3. Afterwards, install the main package, RPy Download
In Debian, its a straight forward…sudo apt-get install python-rpy
