Emacs configs and Github

November 7, 2009 Leave a comment

Its been quite a while since I last had time to write something! Well, not so much as lack of time, but maybe lack of stuff to write about. I have been working in a completely different domain for the last 3 months or so.

Anyways, one of the many things I did to keep my work environment sane and to make my emacs experience better, was to learn a bit of elisp. Then I almost threw away from the previous ~/.emacs that I had, and moved everything together in ~/.emacs.d . Now I’d say thats not the most brilliant idea, since, I made the decision and realised the backup was a week old!

However, my emacs configuration is a lot better now than what it used to be. Things are kept and maintained in a more logical order, or so I presume. Oh! and Github! I now have a real backup system, complete with delta and such.

For the more curious of you, here is the link to the public git repo of my emacs configuration directory.

So let me know how I can improve the elisp-foo in there. Also do share your own methodologies of maintaining your emacs config, the plugins and so on.

Managing my windows

May 17, 2009 4 comments

Hah, what a joke. I have been using XMonad for about a year now (well I kept trying different things in between, but came back to it everytime). The most prominent ones (based on how long I used it) other than XMonad are StumpWM, Awesome (2.x) and Openbox.

This morning however, I was particularly inclined to give ratpoison a try once more. Yes, its StumpWM old stable, but still I thought that since I know C better than Lisp, I might enjoy the experience after all. An hour later of searching through DeviantArt for beautiful ratpoison setups to inspire me, I came across ScrotWM (sounds awkwards I know). It is in AUR, so a makepkg later I was ready to run a spanking new WM, which turned out to be quite a disappointment since xft fonts won’t work, and google didn’t turn up enough documentation. Hell, it aint any different from Awesome and XMonad either.

So, I was getting cosy with a decent ratpoison setup, and a problem with gaps showing up alongside the terminal borders, led me to google and finally to Musca. Yet another window manager. Phew. The developer apparently inspired from dwm and ratpoison, tried to combine the best of both worlds. Guess what, its got a huge thread in the Arch Forums too. How come I didn’t notice it earlier?

So then, as it turns out, Musca is ratpoison (or StumpWM for that matter) with the keybindings done right. MPlayer has some problems getting fullscreen, till I used -fstype=none (yea my friend google told me that), made an alias to set it right once and for all. Its written in C, and only 1 file! Tried reading the source, not much luck there though.

Hence, Musca stays on my system for the time being, and till I re-energise myself to configure it to my hearts content, I am back to XMonad.

Live CD ain’t all that easy

May 13, 2009 1 comment

Whoa. I have been hearing about the linux-live thing for a while now, thought of using it for making a live-cd of the LFS project I was working on for the final year project. Now, while I did follow the LFS book, I wanted to ship with slightly more recent versions of the packages and ended up with kernel 2.6.29

First it complained about AUFS support not being there (yes I forgot to compile that module :P) then the linux-live script worked fine but the resulting iso would only boot into a blank screen. I wish I knew enough to find out what the actual problem was 😦

Turns out there is (was?) another live cd making script available. Larch. Though evidently it is supposed to have been made keeping Arch in mind, the site claims it is compatible with other distros too. Hmmm. Guess what I got with it?

Kernel Panic – Not Syncing: Attempted To Kill Init Error

Wonder what went wrong! Then I got a plan, lets livify the Arch that I use as my main system. 10 minutes later I was starring at the same error. Whoa. I was kinda relieved as I thought that my initscripts were at fault here.

Luckily, my project guide accepted the work without the live-cd and here I am stuck with a final year project and no idea how to show it to the rest of the world!

What time is it?

February 9, 2009 Leave a comment

People using a panel probably has a clock somewhere in there. I know I did, when I used gnome-panel and then later pypanel/tint2 with openbox. Recently, though, I changed to pure openbox, with no panels and system tray. Yes, thats kinda boring, but I still use an old 15″ CRT display and screen real estate is something I don’t like to waste.

Now, while openbox’s key bindings took care of my window managing needs, I started missing the small little clock at the corner. I had conky set up just to display the time and date, but more often than not, it was under the browser or the pdf I was glancing through.

A panel, just for the sake of a clock? Nah thats just preposterous. Then I realised that I already had xbindkeys running, for the mpd controls and all that. So I wrote a really-tiny-little script that displays the time, date and battery for 5 seconds and then goes away.

For the time being, its just a shell script running in an urvtc instance. Maybe someday I will put it in zenity or something like that. However, for what its worth, it shows me the time at a key press, and lets me carry on the good work.

echo “DATE :: $(date +”%Y, %dth %B – %A”)”
echo “TIME :: $(date +”%r %Z”)”
echo -n “BATTERY :: $(acpi|grep -Eo “[0-9%,:]{3,}”|tail -n1)”
sleep 5

Nice and easy, and a proof of the insane customizability of a linux desktop.

Intel graphics and other stuffs

December 30, 2008 Leave a comment

Arch got a kernel update,  kernel26 and xf86-video-intel is at 2.4.3-1. This seems to have fixed the issue with the TTM buffer manager in glxgears somewhat. I now get a fps of around 350, which is way better than the earlier 62fps.

However, the lag is visible just using xcompmgr along with xmonad. Transparnet urxvt seems to have problem displaying more than a couple of pages of scrolling text. Hopefully, the next update will improve it. 🙂

Transparent terminals are probably useless but still somewhat beautiful looking for an otherwise dumb tiling WM.

Yaourt broke due to some update in the AUR website, although its been fixed now. Just enter this command to update yaourt,

yaourt -S yaourt

simple, ain’t it? I just use arson though. Somehow I like to manually do a makepkg and pacman -U 🙂

Xorg7.4 brings input hotplugging and new intel drivers

December 20, 2008 Leave a comment

The recent update in the Xorg package broke the settings for quite a few people. Xorg7.4 brings with it input-hotplugging, meaning that input devices are now detected by hal dynamically as and when they are added. Hence, the good old /etc/X11/xorg.conf now needs to be modified to be used with the new evdev driver.

Keyboard, touchpad, mouse, etc are now to be configured in hal policies, in arch its located here, /etc/hal/fdi/policy/. The wiki entry describes in detail the whole process. Offcourse you can just disable the hotplugging feature altogether, by adding the following in the xorg configuration,

Section "ServerFlags"
Option "AutoAddDevices" "False"

Along with the change in input device configuration, the new Xorg also brings us the new intel driver, which also replaces the i810 driver for intel chipsets. And voila, glxgears no more shows the usual framerate, instead the refresh rate is displayed. It also displays an error regarding the “TTM buffer manager”, which is supposed to be fixed with the arrival of the linux 2.6.28 kernel.

So, those of you who haven’t updated their system yet, take a look around and edit the X configuration accordingly before you restart X and get into a situation where neither your keyboard or mouse works.
