How schools ignore Computer science as a subject

The most ignored of all subjects in the schools in Kerala is COMPUTER SCIENCE. Yes! Students as well as teachers ignore “computer” as  a subject to study. We were happened to market a world-class computer curriculum kerala wide. It is during this time, we got the clear picture of the existing computer training in the state of Kerala.

Pathetic. That’s the most appropriate word to be used. When asked, a vice principal was saying, “We have not a computer teacher actually, our Physics teacher handles the subject, since she is very clever in computer.” We just contacted her, and she has not even the basic clues on computers. Many of the schools says the same story ditto. Even though it is a BIG subject, no school managements consider it in the proper importance it deserves. Most of the public schools in Kerala, follows their medium of instruction as English and thus the faculty of English is the best department in each school. Parents also are bothered only in developing the communications skills of their kids, and thus basic science and subjects like computer are unfortunately sidelined.

Majority of the Public Schools in Kerala still use proprietary tools for training the students while lots of its open source alternatives are widely available. Using the proprietary tools, they spent much and gain less. Recently while Microsoft Windows® XP stopped its support, some schools opted for Ubuntu Operating system. While the State Syllabus of Kerala has adopted open source technology a decade before as part of the “IT@School” project, the Public Schools are far away from its quality.

Today, a computer is not a device for expert jobs. Its essential for our day today affairs, so it should be treated in that importance. The entire curriculum should be designed keeping this fact in mind.

Maria and John play with KNOPPIX

It’s real fun spending time with my small kids before computer. But with too small kids, we can’t predict what they may do with the machine. When John – my sweet little boy – was a very small kid (still now he is) once he switched off the mains power directly while I just went out of the room. That’s why I used ~LIVE~ systems for giving my computer to kids to play their favourite game apps. Yes there is apps for very small kids. Just like TUXTYPE, GCOMPRIS, CHILDSPLAY etc.

Well, I use Knoppix for ~LIVE~ to give my computer to the kids for playing games. Knoppix gives all their favourite apps in one DVD. (Not only games, a lot of other serious applications also bundled with that.) All you can play live from that disc. And before I give it to kids, I just disconnect the data and power cables from my main hard drive. So the operating system will be loaded from the DVD itself. The advantage is, even if the system got an unsuccessful shutdown, it wont affect the hard drive.

John is an excited boy when seeing the computer. Yesterday when he demanded me to switch on the computer, I decided to copy his excitement with my handycam. So I placed the cam very carefully as if it were a spy cam :-)

The Debian way

Is it right providing free and non-free together? Or is it wrong?

The question is real old, dates back since the inception of Open Source Philosophy.

Freedom or slavery

I have used distros like Ubuntu, Debian, Crunchbang, Slitaz and so on. Most of these distros are not 100% free, I do agree. And I used these distros knowingly that they violate the rule of FREEDOM. I always wanted to use only free stuff like Trisquel or gNewSense, but guys, sometimes I need something non-free. The main issues in my case is multimedia file types and applications. I confess that I cannot get away from mp3 nor flash player.

Many free / open source admirers, followers and evangelists still believe that the Debian way is ideal. I heard many FOSS guys admire the Debian way – providing both free and non-free. They argue that the user has the freedom to choose. For a long time, I also agreed with this argument. You choose what you feel best. Freedom our slavery.

What do you share, good or bad?

Well that is the question. What kind of gifts you may give your beloved ones? Good gifts or bad ones? The answer is obvious. Will anyone share ugly gifts to their friends? “Or what man is there of you, whom if his son ask bread, will he give him a bread and snake, thinking he will choose what he wants ;-)” Debian way fails here. Debian provides good and bad at the same time. You can share sweetness, but not bitter. You can share truth, but not false. Bad things are not be shared even if it shares along with good ones. That way, you can share the way to freedom, but you must not lead anyone towards slavery – thats wrong. This insight make Debian philosophy grim. In addition with Freedom, Debian shares slavery too. It promotes freedom in one hand and serves the opposite with the other hand.

Story of his hard disc failed

“Hey!! Do you know anyone who can do a hard disc recovery?” My friend shouts at me on the other end of the line. “I need my data as much early as possible.” He was screaming. Tons of photographs and video files are stored in that cute hard disc. External 1TB USB powered one. It was very portable. Very sexy. Bought one year back for copying data for backup. He was so desperate. I consoled him, asking two questions. “Does your Hard disc making noise, just as triq triq trrriq…?” He said “Nope”. “Then carefully disconnect the cables and come to me.” He did. I connected his cute, sexy, 1TB USB powered portable HD into my old, Debian powered Desktop. It was detected. I showed him his files. Now he was dancing. He tried connecting many computers before that, but none of them even detected it. From his 800 GB of data, his priority was around 80 GB of photographs. I copied it into my computer. Copying all the files, he jumped out from my house and came back after half an hour with some bottles of beer and some snacks. Great! I took part in his happiness.

People buy external hard discs in terabytes today which may be changed to Petabytes and Exabytes tomorrow, which is quite unimaginable right now. The higher the volume, the deeper the loss will be. If one loss a TB of data in a Hard Drive is much higher than 4 GB of data in a DVD. The sad part of the story is that Hard Drive fails much frequently. Why?

Most home users buy huge volume (1TB or more) Hard discs as a back up device. They take a decent backup for the first time. Keep it safe and care it for a couple of weeks. One fine morning someone needed the device to backup some huge movie files from his office or a friend’s computer. Copied the movie files, and the device brought back to home. Some weeks later the same device was shared to someone’s friend to reinstall his Vindoz. Right now the Hard disc has hundreds of movie files. Two months later a new television was bought which has a USB port and now its possible to watch their favorite movies from a small Pen Drive. And you know, what they have been doing, well, its amazing, they started plug the poor backup hard disc directly to the TV USB and started watching all the movies which was resting inside! Wow, what a technology! Some interesting days passed by. One day (after the anniversary of the TB Hard disc, just passed) the disc did not initialized by TV. Cursing the TV, he unplugged it and plugged into his newly bought laptop. Hey! What’s wrong with it? Still the HDD cannot be found. And the pop-up balloon says that error reading device. Ok, then lets try it out to our old Desktop machine, on which we took the back ups many times. Oh! F**k, still it can’t be found. Something wrong with the HDD. Oh! God! There are plenty of photos and videos. How much valuable are they? Lamentation starts and going on.

This is the simple story many home users can say.

What should be the precautions?

Ok. Now that’s it. Keep your data safe and stop lamentation.

Hand of thief

Hand of Thief

OK. Many security experts now say that there is a real Linux Trojan is on market and it started its activity on web. It’s called Hand Of Thief (HOT). It is a commercial malware, comes with its own logo and command & control panel interfaces. Zdnet describes it as a semi-successful Linux Trojan. But still I don’t think it is a fully-functional malware that affects a Linux system which is automatically installed, it may need a basic user permission.

Basically HOT is affected on the web browsers of major popular distributions. Mozilla FireFox, Iceweasel, Epiphany, Chromium browsers are affected. But my concern is this – how this happened. I think it is not Linux vulnerable – but my computer habits are. Wonder why we add such fancy and complicated yet less useful features to the operating system. Doing so, it gets more fatty and thus weaker in the matter of security. A rule of thumb is: the more we make it fancy the less it become secure!

As an additional security, never use any in-built applications in a browser, be it Iceweasel, or Midori or whatever. Instead you open a PDF document in a PDF viewer installed inside your system. Likewise, open an mp4 file in Totem or VLC stand alone application. Please care to update security patches always.
