A hack to rescue Super+P from gnome-settings-daemon

Mon, 09 May 2011 04:01:48 +0000

I like using tabbed terminals, and I like using Super+N ("next") and Super+P ("previous") to switch between the tabs. These bindings have worked well for years, but recently Super+P stopped working for me. Google helped me find two related bug reports: Ubuntu bug #539477: Video out hot key sends super + p + return on [...]

How to capture httplib2 debug in a threaded app

Sun, 29 Aug 2010 20:06:35 +0000

A couple months ago I blogged about my frustration with httplib logging. Andrew Dalke left a comment suggesting that I should replace sys.stdout, something I hadn't considered as a possibility. His suggestion sent me googling, which turned up this old email from Guido. Add threading.local and we have a solution! What we need is a [...]

Python’s httplib uses print for debugging. Oh, it hurts…

Sun, 04 Jul 2010 18:12:24 +0000

At work we have a production site that uses httplib (via httplib2) on the server to communicate with internal servers using a RESTful API. When something doesn't work as expected in this process, we like to know about it, so our app sends email with the exception traceback and whatever relevant data we can pull [...]

a common css mistake

Sat, 15 May 2010 03:39:13 +0000

I'm playing with febootstrap this evening, part of a continuing migration away from Ubuntu toward Debian and Fedora. I googled my way to Rich's febootstrap page. On my browser, it looks like this: The problem is that the page's css has the following rules: h1, h2, h3, h4 { color: #333; } pre { background-color: [...]

daemonizing bash

Tue, 20 Apr 2010 16:32:07 +0000

Before we jump into this, let's be clear about intent: There are better languages for writing daemons than bash. Honestly, any other language is probably a better choice. Writing a daemon implies that you're writing a sufficiently complex program that bash is already the wrong language, with or without daemonization! But if you find yourself [...]

clock trick

Wed, 10 Mar 2010 13:01:41 +0000

I bought a Sony "Dream Machine" Clock Radio about a year ago and have liked it except for one problem: even when the brightness is set to "low", it's still too bright for my taste. Each night I have to rotate the clock away from me on the nightstand so I can fall asleep. This [...]

weechat, nopaste and tagver

Mon, 22 Feb 2010 22:01:51 +0000

This weekend I switched from irssi to weechat. The main reason I switched away from irssi was to gain support for protocols other than IRC. On the way to weechat, I tried Pidgin but I was immediately frustrated by two things. First, I really love running my IM client in screen. I move regularly between [...]

Live migration to RAID-1

Mon, 09 Nov 2009 01:12:56 +0000

I've blogged about using md with lvm before. This weekend I came to appreciate it even more when I migrated a live system from single disk to RAID-1 without needing to unmount or reboot. Here's the overview of the steps I used: Create a RAID-1 on the second disk (sdb). It's initially degraded, meaning that [...]

SHA1 broken by US Government

Tue, 07 Jul 2009 15:08:15 +0000

...but not in the way you might expect. One of us noisers (Gerry Leach) tried to use the Argonne National Laboratory's implementation of SHA1 to double-check his own computations. What he found was a bit of a surprise, to say the least... Given the input string 1316798755 the above site returns DA39A3EE5E6B4BD3255BFEF95601890AFD879. One wouldn't normally [...]

Firefox profiles on Ubuntu

Tue, 10 Jun 2008 20:18:28 +0000

Running multiple simultaneous Firefox profiles is broken on Ubuntu. It works fine on Debian and Gentoo, among others. I don't know if the Ubuntu maintainer is refusing to fix it on the basis that it's an upstream problem, or if they just haven't looked at what the other distros are doing... Anyway, it's pretty easy [...]
