It can be frustrating when the normally-amazing bash_completion (on ubuntu at least) doesn't complete anything, because you're working with a file that's named slightly differently than normal. (Like trying to mplayer a media file with an unusual or nonexistant extension). As a quick hacky fix, put this in ~/.bashrc:complete -p | grep '\-o filenames' |p -v '\-o default' | grep -v '\-o bashdefault

So there was a key generation weakness in Ubuntu openssh packages. The upgrade process regenerates your host keys. But now all of your other machines complain that the host key has changed. And Ubuntu hashes your known_hosts file (HashKnownHosts yes, in /etc/ssh/ssh_config), so you don't know which line to remove. Clean out your whole known_hosts file?No. To find the hashed key, use:ssh-keygen -F

It has come to my attention that some people don't know about sipb-xen.Anyone with an MIT login can get a private virtual server with up to 50 GB disk and 512 MB RAM, free. You have to be comfortable installing an OS yourself, but it's not hard, and there's a clone option for getting a Debian machine. Once up, your server will be accessible at servername.servers.csail.mit.edu.

The pen button is much more useful as a right click than a middle, but it defaults to middle.I thought I could fix it with xinput, like:xinput set-button-mapping stylus 1 3 2but this turns out not to work.What actually works (from the Ubuntu bug) is:xsetwacom set stylus Button2 3I added this to the GNOME session (system->preferences->session).

Here's a basically US-English Dvorak layout, with right Alt meta mapped to give you Spanish characters right where you'd expect them: meta-vowel is accented vowel, meta-n is ñ, meta-1 is ¡, and meta-/ is ¿.Add the following to your /usr/share/X11/xdb/symbols/us file:partial alphanumeric_keysxkb_symbols "dvorak-spanish" { name[Group1]= "USA - Dvorak with Spanish extras"; include "us(dvorak)"

I've found two IMAP libraries in Common Lisp: mel-base and Franz's postoffice. Neither supports SSL as far as I can tell. Most IMAP servers now require SSL. Do I take that to mean that no one is doing IMAP in LISP anymore?btw, mel-base currently doesn't work with Allegro.But you may find this optimization helpful.

The Toshiba M200 is a relatively unimpressive tablet PC that I've borrowed for an extended period. The Windows install on it was performing terribly (I also have Linux on it), so I decided to recover it from the recovery DVD.Two days later...Here's what didn't work:Booting the DVD from GRUB (it doesn't know how).Booting from a Philips SPD3100 external DVD drive.Booting the floppy image from that

The God of Peace Brought from the Dead the Good Shepherd Jesus will always be our shepherd and we will always get the incomparable joy of being his sheep.John Piper's Easter message. Starts off a little awkwardly, but looks good so far. I've only watched through the first point.always sheep in need of a shepherd. ... and most of our shepherds suck. ... which is why we need Jesus as our

Sunday: slept in, walked to CityLife in the afternoon, met Brandon there, excellent refreshing and solid service (!)--I'll be going for the next few weeks at least, God willing--caught up with Brandon afterwards, took T back, ran into Emily Veysey sitting right next to me..., ran into the Cambridge carnival at Kendall, caught up with Sarah and Matt, met other new people at Ashdown computer

I've been saying this for years, perhaps not as forcefully. See "Ken's Stuff Manager" proposal for implementing this. I thought about it first really in the domain of the Bible, capturing all of the different kinds of ways that verses/chapters/topics can relate to each other. More recently I've also found it in just making lists (e.g. friends), or coding (concepts and their relationships). OOP is

The Mexicana flight arrived in Mexico City around 10pm, but we waited in the plane for a while for a bus to come pick us up. By the time the bus found its way back to the terminal, it was nearly 11. I found Oscar's uncle Hugo and his son Juan Pablo waiting for me, holding a sign with my name. I readily confirmed that they knew Oscar and weren't just random people. I checked at Aviacsa to see if
