“Hacker” : the misnomer

Who is  a Hacker?

There is a common belief(created by media….again),even among geeks  that hacker is a person “who breaks into computers and is involved in mischievous and illegal activities related to computers”. Unfortunately, the above explanation in quotes would better suit the word “Cracker”. Then who is a hacker?

It is best said in the words of  Richard M Stallman.

Richard M Stallman has made it clear many times, “A hacker is someone who enjoys playful cleverness—not necessarily with computers. The programmers in the old MIT free software community of the 60s and 70s referred to themselves as hackers. Around 1980, journalists who discovered the hacker community mistakenly took the term to mean “security breaker.

Adobe CS5 : the next generation suite

Adobe has released its CS5 suite of creative tools and to describe it  in a line “It’s mindlowing”. Of all the features advertised of its components the “Content Aware fill” effect of Photoshop CS5 is what attracted me the most.

Easy way to install fonts in Fedora

This font installation procedure was tested successful in Fedora. As a matter of fact it works fine in all otherLinux distros too 😉

After an unsuccessful desperate attempt to install Microsoft fonts in Fedora i started to think over easier ways of installing other fonts.
I found one well known solution and applied the same  to the Windows fonts (and yes
i am running a dual boot of Win7 and Fedora11).

The trick is as follows:

First, Copy the purchased Windows fonts from your Windows disk onto Fedora. If you choose to install the fonts only for the current user then move the fonts to .fonts directory in the user directory.
Else if you want the fonts to be available to all the users you must move the downloaded fonts to /usr/share/fonts

Moving the fonts to /usr/share/fonts
1. Open
2. cd <location where you have placed the font>
example. $ cd Desktop/
3. mv <fontname> /usr/share/fonts/
example. $ mv fertigo.TTF /usr/share/fonts/

4. Log out and then login , open any editor and see the fonts in action.
Enjoy 🙂

Extra info:

  • Have a look at my favourite list of professional fonts <here>

  • Also  note that if you plan to install the fonts only for the current user then move the fonts to .fonts directory in the home folder(View menu —> show hidden files).

If that directory does not  exist then create one yourself.

  • If you have installed the xfs fontserver (it is not installed by default in Fedora 11), then run the following code to reload it:

su -c ‘/sbin/service xfs reload’


su -c ‘/etc/init.d/xfs reload’

VIT professor gets US patent for hydrogen production method

A professor at the VIT University in Vellore has been awarded a process and technology patent by the United States Patent and Trademark Office for conceiving a system for the production,storage and dispensation of hydrogen from encapsulated metal hydride shells for running vehicles more efficiently.

Professor R Natarajan,general manager,Energy Centre, VIT University,received the patent certificate last week.
The patented technique is modelled on a twochamber /tank process in vehicles.When the hydrogen production from the first tank is stopped,the second tank starts automatically producing hydrogen and thus ensures continuous supply of hydrogen.A US company is using a similar concept but through a single-tank technique,which is complex, Natarajan said.duced by reacting sodium hydride with water.This is unlike the conventional process,where sodium hydride is heated to a high temperature and then decomposed to produce sodium and hydrogen.Also in this technique one mole of sodium hydride will give one mole of hydrogen,unlike the conventional process where two moles of sodium hydride is required to produce one mole of hydrogen, he explained.
Another advantage is that the hydrogen is produced at required rate and pressure only and hence ensures safety in the storage and transportation of hydrogen.Since metal hydride is encapsulated inside plastic balls even in case of accidents we dont expect any fire or explosion hazard, he said.
We understand that ISRO is working along with Tata Motors to develop and demonstrate a hydrogen fuel cell bus for which the fuel cell is imported from Canada.They can adopt the hydrogen dispensing system developed by us instead of importing and using the liquid hydrogen or high pressure hydrogen storage and dispensing system, he added.
