Luke’s Life

I’ve been working a lot on a research project for one of my Professors which has most recently involved a lot of compiling on an old Sun (we need the 16GB of memory available on it :-) ).  I spent literally two days trying to compile omnet++ and the INET suite.  I finally managed to get it working after some consultation with the #solaris channel on freenode.  Therein lies the problem.  I think I’ve just dragged myself into irc by finding the #hamradio channel.  I think ham radio is my nerdy guilty pleasure.  By idling in that channel I’m finding out all sorts of interesting things, and again reviving this latent desire I have to get a ham license.  For now, I may have to learn CW so I can use cwirc:

This semester has been interesting so far, but I’ve been focusing a little bit too much on my research at the expense of my other classes.  I suppose that means I like the field I’ve chosen, so its not too bad… but I need to put some more time into studying for  GEO and EE.

On the party watch:

Last week – Chris turned 21… boat party on lake austin!  Chris knows lots of pretty girls.  It was a good night.

This week – superhero party?  This might be interesting.

Morse Code Influences on Ham Radio Lingo

Posted in geeky, school by lrobison on March 26, 2007

I wrote this paper for my linguistics class. Since I did most of my research through the Internet, I thought I should post my paper back to the Internet. I also posted the paper in pdf form here: Morse Code Influences on Ham Radio Lingo

Morse Code Influences on Ham Radio Jargon

The origins of much of today’s ham radio jargon traces back to early codewords and usages of Morse code. Codewords are short sequences that are sent by encoding each character of the word in Morse code, and tapping out that Morse on the radio, just as you would send any other word. To understand the jargon used by amateur radio operators, one must first consider the origins of radio communication. Samuel Morse introduced Morse Code and the telegraph in the 1840’s and 1850’s, and his invention spread rapidly through the states, especially along railroad lines. In 1896 Marconi was the first person to send Morse code by radio waves, and amateur radio was born. By 1912 radiotelegraph had grown enough that Congress begun to regulate the frequencies available to amateur and private stations. These stations all used Morse until voice transmission was made possible in 1920, although Morse was still in common use through the 1950’s…

“seriously, the set of computable numbers is countable! you can arrange them all in a series – what kind of set is this?! yt is nah-thing!!”

-lifshitz (read with a russian accent)
on computable numbers vs uncomputable numbers. basically every number you can begin to describe is computable, yet there are infinitely more uncomputable numbers.

More on backups

One other thing i forgot: the social bookmarking site.

All my bookmarks, tutorials, blogs and interesting sites are saved there. And firefox has a great plugin called foxylicious that imports those bookmarks to your local firefox bookmark folder. It works quite nicely if you use tag bundles.

My laptop hard drive just crashed last night. completely dead.
It started with a whiring clicking sound, thats when i got suspicious. I scrambled to back up my project, but all file accesses just hung forever, waiting for a response from the HD. then the system froze. I tried to reboot, but was faced with “No bootable devices found”.
Now I have to restart my graphics project. I’ve lost my recently written memory debugger, and lots and lots of other small utilities. I think other than programming i don’t even care about anything else that was on there. Except my private GPG key. Which brings up an interesting point: If your GPG key is on a hard drive that crashed, any emails/file encoded with it went down with the hard drive. So how do you keep a private, yet redundant copy of a GPG key? i guess more hard drives… maybe a raid1. This is my second laptop harddrive to crash, although the first one gave me more time to save stuff. I should really learn to be more religous about my backups.

On the plus side:
i use IMAP, no emails are lost
I copy projects to the CS servers for testing and submission, no old cs code was lost
my important pictures are on flickr

so really the only things I cared about loosing were the other pictures not posted to flickr, and the CS projects that i had not yet completed. The utilities that i had laying around (like that fancy new memory debugger) will also be missed.

Daddy always told me to backup. Moral of the story is listen to your dad.

Google Talk gets jabber s2s working (finally)

Posted in geeky, Uncategorized by lrobison on February 13, 2006

Looks like google finally decided to open up their jabber server to the rest of the world. We can now talk from a gmail account to a account, or any other server. yay! I’ve tested it with my own jabber server, (click for full size)

And then comes Ubuntu

ubuntu logoDisclaimer: this post is not really about me at all, but about my break-up with gentoo. If you don’t care about linux, don’t bother reading it. If you are scared of linux, install ubuntu.

I ran gentoo linux on my laptop (Dell 600m) for the last year or so, and while it was fun, and moderatly easy, there were several hardware things that just didn’t work. Recently I updated my gentoo kernel, and broke all wireless drivers. The whole point of the kernel upgrade was to improve my chances of getting direct rendering working, but that didn’t work either. Just because I could, I tried downloading gentoo’s suspend2 sources, a kernel with the primary objective to get suspend working in linux. Well, guess what, that didn’t work either. Last night I finally got fed up with gentoo not working, and decided to download the new debian-based Ubuntu. (Just a side note, ubuntu might have been the fastest off-campus thing i’ve ever downloaded, as I hit a full 1000Kps using the torrent).

The next morning I didn’t want to do my homework due later that day, so I decided to burn the CD and install. The whole process of backing up, installing, and restoring took a little over an hour. On the first boot I had sound, direct rendering, wireless drivers (including a wireless manager), acpi events (lid close turns off screen), and even 2 levels of suspend!!! I had spent a total of over 40 hours trying to get those things all working at the same time on gentoo, and had failed. Ubuntu came up with them all fresh out of the box. Way to go ubuntu. It was nice gentoo, but its time for me to move on.
