Dual-screen setup with aligned bottom edges

For the sake of anyone else who's fighting their screens, I've got a script that will do this (but very very slowly)

setup script

xrandr --output VGA1 --auto xrandr --output LVDS1 --auto xrandr --output VGA1 --rotate left eval "`monconf`"

monoconf script

#!/usr/bin/env python import subprocess output = subprocess.check_output(["/home/tag/.bin/mon.ls"]) output = [ item.split() for item in output.split("\n") ] mons = {} for mon in output: if len(mon) > 0: if mon[1] == "connected": res=mon[2] res=res.split("x") for item in res[1].split("+"): res.append(item) res.pop(1) mons[mon[0]] = res BOTTOM_LEFT = "LVDS1" TOP_RIGHT="VGA1" LEFT_WIDTH = mons[BOTTOM_LEFT][0] LEFT_HEIGHT = mons[BOTTOM_LEFT][1] RIGHT_WIDTH = mons[TOP_RIGHT][0] RIGHT_HEIGHT = mons[TOP_RIGHT][1] print "xrandr --output %s --pos 0x%s" % ( BOTTOM_LEFT, (int(RIGHT_HEIGHT) - int(LEFT_HEIGHT))) print "xrandr --output %s --pos %sx0" % ( TOP_RIGHT, int(LEFT_WIDTH) )

and the mon.ls command

xrandr -q | grep "^[^\ ].*" | grep -v Screen

All of this is super hacky, but it works.

libolla (from the useless script department)

Hello, World!

Today's hacks come remotely, on the first day of my long trek to Cleveland. As many debian readers know, debian URLs are usually transmitted over IRC or email with some snappy abbreviations. Usually, you'll see something like:

Feel free to check out information about frob at wiki.d.o/Frob

or something like:

I have uploaded package bar onto mentors.d.n for review

What bugs me most about this is that I have to expand URLs by hand. Which is lame. Enter libolla (a fitting name as well as a graceful nod to my alma mater John Carroll University's crest).

When LD_PRELOAD'd, it'll intercept and expand calls to getaddrinfo transparently. It seems to work fine on SSH, and chrome (but I can't test well, since I'm not on a real line).

This was all hacked up in a few hours I had to spare, and without any sort of internet love, so I'm willing to bet there are some bits that can be cleaned up (after all, the name of the blog is "Peace, Love and C++", not "Peace, Love and C" - I don't clam to be a c expert ;) )

So, feel free to fork the project on github (or as I can now do - http://g.c/paultag/libolla)

Now, I just need to find a way to globally pre-load this for apps that I start in my DE. Should be easy enough fiddling with some env-var files.

Stupid Hacks: Colorizing files

Presenting another script from the useless script department -- `dog`!  It has an in-built (and rather quirky) state-machine style parser, which will emit the color defined on entering the new state. The syntax is stupid easy - and hopefully easy enough to write. Perhaps (given some time) I'll turn this into something, well, useful. Code's on [github](https://github.com/paultag/dog), but very buggy and stuff. Also hard-coded. Enjoy!

Stupid Hacks: GIF -> ANSI

In honor of the recent nyan-cat ANSI fad, I hacked up some goodies that is able to do this with a small subset of all gifs - namely those which are well-formed.

The code is thrown up as a gist -- it uses some code from Micah Elliott's colortrans.py.

Another post from the "Useless Script" department

A while back I wrote some nodejs that mish-moshed email and web 2.0 long-poll action into a very ugly, but fairly up-to-date showing of debian changes. That is over on my server here.

The code's fairly simple, so I also wrote a python consumer here.

Since it's so simple, I've pasted it below, too.

Feel free to use (but please not abuse) my server :)

#!/usr/bin/env python import time import urllib import json service = "http://pault.ag:8080/tail" lastts = 0 def loop(): global lastts while True: f = urllib.urlopen("%s?since=%s" % (service, str(lastts))) msgs = json.loads(f.read()) for x in msgs['messages']: print x['text'] if lastts < x['timestamp']: lastts = x['timestamp'] loop()
