KWallet Security Analysis

published on
KDE 4.12 comes with a KWallet GnuPG backend, which is more secure. More info here, including how to move existing wallets. (Note: Tom Leek has written a more detailed analysis on StackExchange.) I started using KWallet a few months ago to stop reusing same passwords on multiple sites. Using KDE Wallet plugin for Firefox, I setup my passwords to be automatically stored in a KWallet file, which was the best solution I found for Firefox on Linux (other than Lastpass, but it stores passwords remotely and is closed source, which I don’t prefer when dealing with passwords).

Streaming to from Linux

I was looking to stream to from Linux, but none of the existing solutions were embedding the webcam over the captured desktop. Since works with rtmp, and existing scripts were using ffmpeg, it was easy to modify the script to add the camera as an overlay.

zsh is really awesome

published on
A few months ago, I decided to try out zsh as my default shell. It’s very similar to bash, but is much more powerful. My favourite features so far: Shared command line history among all sessions. I usually have at least 4-5 shells open, and the command history being shared among them is awesome.
