Let there be light, in skype!

At home, my video would always show a silhouette in G+ and Skype, and I always thought that this was because the lighting at home was not sufficient. At office, the video was decent. But, moving to sit right under the light also didn't help much.

Struggling with a bunch of tools like v4lctl, guvcview didn't help. But, during these struggles I noticed that cheese would show me bright and cheerful, while all the other programs showed my silhouette.

I set out to "fake" the output of cheese as a video device that skype and other programs could use. But, I didn't have to go all the way. I ended up using v4l2loopback to create a loopback video device, and just using gst-launch to redirect video to that device, did the trick! Thanks gstreamer! Thanks v4l2loopback! :)

Here's a convenient script to use it every time I need it.

numpy, pacman and me

I'm now officially a part of the Arch Linux community! Arch Linux is a lightweight and flexible Linux® distribution that tries to Keep It Simple.

I have started using arch from less than a week or so. It took me a while, not too long, to realize the beauty of this distro. I was trying to tweak the settings of my org-mode's remember (on Karmic), trying to make it work the way I liked it. After breaking my head with .emacs and lisp for a while, I realized the version of my org-mode was way different from the version of the docs, I was reading. It didn't take long to figure out, which version of org-mode to get. As a matter of curiosity, I checked AUR for the version, and true to Arch's reputation it was bleeding edge! I was still using Karmic, since I hadn't got my Arch installation working the way I like it, yet. Out of laziness. sudo reboot; to hell with laziness!

I was setting up things I regularly use, tweaking my way around. After a day or so, I find python-numpy is out of date. And to top it, an orphaned package! I didn't feel one bit good about this. After some futile attempts to suppress my discomfort, I sat down to work.

After an afternoon of effort, I created my first PKGBUILD. :) I now have python-numpy installed using pacman! Pleasure to join the Arch User Community! Also, thanks to lifeeth and Lynus Vaz, for the sparks.

PS: I'm using Arch with Openbox. It's neat! PPS: org-mode is really awesome! It's a world in itself. life in plain text, truly!]
