aptitude install build-essential libxml2 libxml2-dev python-dev

- then configure, make and install libsbml:

./configure ––with-python (execute from the directory where the downloaded libsbml archive was extracted to)
make
make install
ldconfig

- then check if installation was successful:
python
and when the python prompt >>> appears, run from libsbml import * – if there are no warnings/errors, then you are done!

• The workflow described here is optimised towards backup and security
• This workflow reduces administration tasks during future server migrations

Note that these articles explain the workflow I follow. There are of course many other ways to approach the same problem. Please do let me know if you have a better method.

Software Required

MoinMoin Version
At the time of writing this, the latest stable version of MM is 1.9.3. However, you can adopt the methods described here on previous versions as well. If you are new to MM, there is less chance of you noticing any differences between the recent versions.
Platforms
I have been using this appoach on Ubuntu 8.04 LTS (Hardy Heron) onwards. Currently, I have Ubuntu 10.04 LTS (Lucid Lynx).
Requirements
Have a look at this link on MM website to have a list of dependencies for different versions.

Articles in this series will be describing MoinMoin 1.9.3 on Ubuntu 10.04 LTS. However, I would like to reiterate the point that you can use it on other combinations as well.

Installation
The actual installation of MM on Ubuntu is as simple as typing the following code:

sudo apt-get install python2.4-moinmoin

This will install MM at /usr/share/moin/ and the config files will be stored at /etc/moin/. The issue with installing at this location is that most of us dont normally backup /usr/share/. Personally, I prefer to keep all such important applications under /usr/local/applications/ directory. I take particular care to make regular backup of my /usr/local/ directory. This way the only thing I have to do in case of a server crash of some sort is to restore this directory. So, how do we install MM to /usr/local/applications?

• Download MM from here
• Extract using tar as follows
  tar xvzf moin-x.x.x.tar.gz
• Navigate to the directory where you extracted MM
• Install MM using:
  python setup.py install --force --record=install.log --prefix='/usr/local/applications' --install-data='/usr/local/www/template
  where:
  –force = To overwrite outdated files in the destination (not needed in this case).
  –record = This is the install log. Keep this safe, just in case.
  –prefix = Our installation location. This is where our MM installation is now located.
  –install-data = This where we are going to keep our MoinMoin instance. Read my second post in this series to see what we do with this directory.

Great! we have MoinMoin installed on our server. In my next post I will explain how to get our first wiki on the internet. All the above information is explained in much more detail in the MM website and also on the install.html file that comes with the MM download. But then, you wont be reading this if you have read those documents!

Now that I have started working with RAW and DNG photographs, my workflow demands an efficient backup solution. I work on these files using Adobe Lighroom and Photoshop (I prefer them more than Gimp) on a VirtualBox WindowsXP. I have configured luckyBackup on my server to make backup of my RAW files every 12 hours to two independent locations – an internal backup only hard drive and a portable hard drive. luckyBackup emails me when the target directories are 25GB in size, so that I can then write it on to a Blue-Ray disk and lock it up safely.

sudo fc-cache -fv

To use it with LaTeX fontspec package (it can use open-type fonts directly in your document), you will need is to take note of the exact name of the font family. For that, after having installed the lcdf-typetools Ubuntu package, you can do something like

otfinfo -i /usr/share/fonts/AGaramondPro-Regular.otf | grep Family

sudo apt-get install sshmenu-gnome

Note that you have to add it to the gnome panel to use it.

sudo apt-get install incron

Before starting to use incrontab, we must give permissions for a user to use the service. To do this do:

nano /etc/incron.allow

and add the desired username to it.

Using incron is very much like using cron, ie. you can list, edit, and remove incrontab entries by using -l, -e and -r options, respectively. Have a look at the man page (man incrontab) for more options and the directions for usage.

man 5 incrontab will show the format of the crontabs we are going to create. Basically it is as follows:

path mask command

where path> can be a directory or a file that is watched. path> can be one of the following:

When monitoring a directory, the events marked with an asterisk (*) above can occur for files in the directory, in which case the name field in the returned event data identifies the name of the file within the directory.

Let’s create our first incron job. We’d like to monitor the directory /home/Downloads, and whenever a pdf file is downloaded into it, we want incron to activate a script that moves the file to another location. This is how we do it:

incrontab -e and put the following text into it.

/home/Downloads IN_CREATE /home/xxxx/.mvpdf.sh

Once the file is saved, type incrontab -l to see a list of incron jobs.

Test if everything is working as intended.

When screen is invoked, it executes initialization commands from the files “/etc/screenrc” and “.screenrc” in the user’s home directory.

Simply create a file in your home directory with vim or some other editor.

$ vim ~/.screenrc

And place the following line in the file.

caption always "%{Wb} %H %{Bk}| %{Ck}%-w%50>%{Cb} %n %t %{-}%+w%<%{- Wk}%{Bk} | %=%{Wb} %C "

Now launch a new screen session for it to take effect.

sudo apt-get install bwm-ng
sudo apt-get install iftop

Enjoy!

sudo apt-get install lynx

Now, make the following script:

#!/bin/sh

lynx -dump "http://wordnet.princeton.edu/perl/webwn?s=$1" | grep -B 1000 References | grep -A 1000 relations | less

Now you can define any word from the terminal. For example, suppose I want to know the definition of ‘psychoanalysis’, I can simply run:

./define psychoanalysis

and get the definition printed out.

It’s nothing fancy; just grabs the output from an online dictionary and spits it out to the terminal, but I find it to be very useful.

As this is a non-destructive operation and dirty objects are not freeable, run:
sync

To free pagecache:
sudo sh -c "echo 1 > /proc/sys/vm/drop_caches"

To free dentries and inodes:
sudo sh -c "echo 2 > /proc/sys/vm/drop_caches"

To free pagecache, dentries and inodes:
sudo sh -c "echo 3 > /proc/sys/vm/drop_caches"

Hope this works for you all.
