Published at May 13, 2012 · 2 min read
How mutt can handle mails in html format ? Takling about html mail handling is talking about handling any type of Multipurpose Internet Mail Extensions.

Published at May 13, 2012 · 2 min read
This is second post of mutt tutorial series. As in the previous post for below information I need to thank Kousik for posts about gpg and using it with mutt.

First of all we need to install it by simply: 1 sudo apt-get install gpg After that we generate our keys by:...

Mutt tutorial part 1 - setup IMAP account
Published at May 13, 2012 · 3 min read
Mutt is one of those programs that make people call you a linux geek, nerd or a snob. This is because using TUI or command line tools in world of fancy GUI for most people is weird. What’s so great about mutt? I probably still have not found much of its advantages, but at first glance we can notice a few things.

Published at April 12, 2012 · 4 min read
Unfortunately after few tries of cross compiling eglibc using different source for instructions I always end with hard to solve issues. Luckily, in the sources of eglibc I noticed instructions for cross-compiling written long time ago by Jim Blandy(I know i should start here). Lot of thanks to him for it. Below I describe my experience which I gained during eglibc cross compilation for arm-unknown-linux-gnueabi and procedure that I used. Commands below contain some constants that I used in previous works....

My main goal is to use a component based on the GNU public license, and using them in as the newest version as it is possible....
