Shantanu Vs The World

last update:

I wrote this script a few days ago to plot real-time / streaming data with gnuplot. The motivation was that I needed to test a piece of code for a touchscreen driver that I had written at work. The issue was that the UI wasn’t quite ready yet, so I wanted to test just the driver to be working fine. Now, the very first thought for the software to use that came to me was “gnuplot” but I found that it can’t really do this in an easy way.

RT-GNUPlot-ter

This is a script to plot streaming / real-time data (i.e. plot the points as the data comes in) with gnuplot. The script is written in perl and works in windows as well as linux. Please read on to see the requirements, installation, usage and download link. I should also thank my colleague Rabindra Mandal, who gave me the initial idea and Thanassis Tsiodras, whose script I looked at before creating mine (though mine is quite different in nature.

If you can’t get tail command to continuously monitor a file, then read on. I was working on a script yesterday, a part of which depended on continuous monitoring of a text file. I had used our trusty old “tail” command for this but while testing by manually putting in some data into the file, it was failing but curiously it was working fine when used in actual scenario. Befuddled, I did a simple test.

This is just to let you know that a few of my friends have started Overclocked, a haven for PC enthusiasts in India. Overclocked is an online store for the people who like to stretch the performance of their machines to the maximum. They store a lot of high end computer stuff that isn’t easy to find in India and that too for a reasonable price. They also assemble mean gaming machines while giving you quite a bang for your buck with gauranteed satisfaction, shipped anywhere in India, and that’s not all, they can personalize it too with a variety of custom modifications (I really like their laser engravings).

I generally move from LTS to LTS releases of Ubuntu but reluctantly had to update my system to Karmic when my old HDD gave in. I also thought of trying out Kubuntu (KDE based) this time as I had heard that its doing a lot of interesting things (Akonadi/Nepomuk etc) and that with 4.3.1 it is stable as well. The installation went fine, all over within less than half an hour and then the problems started.

I recently got hold of a Guitar Hero controller for my PS3 but the game still had some time to come so I tried it out on my laptop with Frets on Fire (rather FoFix). But when I started it, it was crashing with some weird error about not being able to open mixer devices. Searching on the google, I came to know this is happening because of Pulse Audio as this application needs direct access to the sound devices and finally I came upon **pasuspender.

Killzone 2 (KZ2) is one of my most favourite games for the Playstation 3. Killzone 2 is a very different game as compared to the other run-of-the-mill FPS’s out there. Now, I might not be the best player out there but I’ve played my fair share of it. So, I thought of jotting down some quick points for the different classes, how to play them and how to make the most of them according to my opinion.

If you are a proud owner of an Asus WL-500W wireless router (or maybe another one of the same series like wl-500g, wl-500gp, etc), then you know that this router has a very useful USB port with which you might have attached your external hard disk and have already offloaded all your downloding tasks to it, or maybe using it for various other purposes. Whatever maybe the reason, the main point is that because of this hard disk, now we cannot just turn off the power of the router any more.

A few days ago, I had to install Windows XP as a guest OS on my Ubuntu Hardy machine as I needed to carry out some Visual Studio work. What I noticed was that my CPU usage went through the roof (constantly at 100%) even if the guest was completely idle. Result: My laptop was shutting down within a few minutes because the CPU was heating up and its temperature going beyond 75C.

FireFly is a nice DAAP based media server that allows you to listen to your music collection anywhere using any DAAP based client like iTunes, with other players (like Winamp, Rhythmbox, VLC, etc) using plugins, or it even has its own dedicated php/flash/java based clients that can be fired up on any platform any computer giving you instant nirvana. Many people, like me, use it on their Routers or NAS boxes to access their music anywhere without having to keep their home PC running or lugging around external drives.
