XMonad: a tiling window manager

May 282011

I present to you today this very useful article introducing xmonad, an alternative window manager, the article is bt Fabio Viola and can be found along with many other interesting articles on the page of SaLUG Journal(In Italian), the article is released under the GNU Free Documentation License, translation from Italian by me.

Last week in Bologna I had the pleasure of knowing a geek from Padua, a smart boy with whom I had a chat.

He Introduced to me an interesting project, it is xmonad . On the official website [0] there is a phrase that strikes you and takes you to devour each page of the documentation or makes you close in a flash, the browser tab : “In a normal WM, you spend half your time aligning and searching for windows.” If you recognize yourself in this sentence xmonad is for you.
What is it?

It’s an intelligent window manager written in Haskell whose ‘main’ peculiarities is to automatically position windows without overlapping. Xmonad has several advantages (which i found on the homepage of the project): tiling windows, minimalism, stable (and having tried hard, I can confirm), extensibility, many features (for example, supports xinerama), simple, supported .. .

Playing with LVM, on any existing disk.

I’ve found these useful examples about LVM, Article By Roger Hosto

Let’s start with what LVM is; in short it’s away to manage disk volumes in more of a user friendly way, whether they are whole hard disk, disk partitions, or SAN disk. Logical Volume Manager gives the Administrator much more flexibility in allocating, re-sizing, and moving storage around. With that being said, the greatest advantage is having the ability to add additional disk space with relative ease, which with Moore’s Law and Kryder’s Law [1] floating around makes life a little easier on your System Administrator.

Now that you are all interested in using LVM, let’s bust out a new hard-drive or re-partition our hard-disk and have at it. Woo! Hang on a minute! That sounds like a pain just to play around with something. That’s what I thought too, so here is a way to use your existing partitions using loop devices and empty disk images to play around with and get use to the commands.

I have personally tested this on RHEL 4 and 5, but I don’t see why this couldn’t be done on any current version of Linux.

I’ve found this terminal while testing Crunchbang, Terminator is CrunchBang’s default terminal. Its based on Gnome terminal, its best feature is it’s ability to show multiple terminals on one screen, but it also uses tabs aswell.

It is inspired by programs such as gnome-multi-term, quadkonsole, etc. in that the main focus is arranging terminals in grids (tabs is the most common default method).

Remote control by Java and 8 bit

I’ve received this introduction from my friend Paolo Proni and i gladly publish it:

From longtime the common opinion about Java is that it is a heavy environment, which requires a powerful hardware and sometimes it seems the power is never enough. It seems that in order to do the same tasks that we could do 10 years ago, even the last generation machines are not enough.

That is simply not true.

The slowness of many Java programs is due to the wrong choices of the software architects, who have given a low priority to the efficiency, preferring the extreme flexibility or the productivity, when it was the case of not concentrating to the delivery time only…
It is a plaisure to discover on the Internet some little jewels, such as the Tini , where a 8 bit microcontroller can run some small Java programs in a decent way.
