With the recent release of Ubuntu 8.04 (Hardy Heron), a lot of hype was generated (Overhype or well-deserved, that’s for another post). One of the main highlights of all the stories, news and reviews doing the rounds are that this is an LTS version. But many people, mostly those who are new to Ubuntu, and even a few who are already using it, are not sure what LTS really means.
For the past many years, I’ve seen a trend that has been on a meteoric rise. Whatever new service you sign on for on the internet (especially the web2.0–oh-so-cool-you-have-to-tell-everyone-about-it ones), it gives you an option to fill in your e-mail ID and password and makes a generous offer of letting all your friends know about your new avatar and let them all join in the fun. Most of the people around me, it seems, don’t think twice before gladly accepting the offer, as is made apparent from the increasing amount of automated mails I’m getting with subjects like “Hey, don’t be left out!
Worried about someone breaking into your house in your absence? Or just need to keep a tab on who enters your room while you are away? Well, all you need is a webcam, a linux PC/laptop and a twitter account. And you are set for real time updates through twitter about all that goes on at your abode behind your back (can even receive a text message/sms on your phone). Keep reading for the very simple setup you need.
Did you know that instead of installing special software to view your webcam video, you can simply use mplayer for the same purpose, and with a lot of fine control. e.g. try running the following command with your webcam attached to your computer. mplayer -fps 15 tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0 And you can use mencoder to capture and encode video from your webcam: mencoder tv:// -tv driver=v4l2:width=60:height=40:fps=60:device=/dev/video0 -nosound -ovc lavc -lavcopts vcodec=mjpeg -o test.
I have an old noname cheapo webcam, that I dusted out of my junk (why? More on that in a post coming soon). I hoped that it would work in my Ubuntu setup out of the box like most of my other hardware. I connected it to my laptop’s usb port. dmesg gave the following output: [21328.211333] usb 1-1: new full speed USB device using ohci_hcd and address 2 [21328.319698] usb 1-1: configuration #1 chosen from 1 choice [21328.
HTC announce their shiny new Touch Diamond recently. Everyone ooh’ed and aah’ed while ogling at it until they realized that HTC has taken a step back (or forward towards matching Apple’s iPhone crap) by removing the expansion card slot from the phone. Yes, it has 4 GB of internal storage but I’d rather have an SDHC card slot with the ever falling prices of solid state memory (an 8 GB Class 6 SDHC card is worth not more than around 60$ these days).
GLib - An Introduction: GLib is a utility library for C, which augments the standard C library in several purposeful ways to make your life that much easier while programming. GLib has the following things to offer you: **1. Portability: **The main issue that haunts any C developer is the portability of code. One cannot rely on the standard C library for this as you may find many functions that work differently under different platforms are aren’t there at all sometimes.
If you have ever had these errors or just want to be prepared in case they pop up somtime (and they surely will), then read on as I discuss various situations that lead to them and also their solutions. I generally use desktop clients (mostly blogjet, but also Windows Live Writer and Scribe Fire sometimes) to blog to my WordPress based blogs. Some months ago, I started getting “Http 406: Not Acceptable” error while posting a particular post.
I installed google toolbar (linux version) today in firefox and for this blog, it says that its page rank is 7. I can’t believe my eyes. I suppose it’s a google glitch may be (but have a wishful thinking at the back of mind that its true :-) ). Are you getting the same result for this blog (or weird page rank results for other places that you frequent?)
Some of you might know that I was in the hunt for a decent mspaint alternative recently. Note that I didn’t go for GIMP / Inkscape etc because they were overkill for what I wanted to do. Many a times, I just wanted to touch up a screenshot or make a simple flow image by drawing a few boxes, use a few pointing arrows, and add some text here and there.
