Studying?

Final exams have begun. I had my first one today. Physics, it was. I did pretty well, too. I got an 85. According to my calculations, this means I'll have a B in the class, which is good. I didn't even have to study that much. Now I need to study for Differential Equations, which I also spent time studying for last night. I'll need all the studying I can manage to make myself do.

Last night, my roommate, Adam, was reminiscing about Nickelodeon's Super Toy Run, the annual sweepstakes in which the winner would go to Toys 'R' Us and have a few minutes to fill a shopping cart with anything they wanted. I mentioned how it reminded me of "Supermarket Sweep," a '90s game show which was about exciting as it sounds. For old times' sake, we watched an episode on YouTube. Check out the description for the video. The uploader (who appears as a contestant in the episode) says that the audience consisted of paid extras who were only present for the taping of the beginning of the show. So the rest of the applause throughout the show is canned. We noticed how strange it was that the contestants would clap for themselves when they got a question right; it's because no one else was actually clapping for them.

Boring technobabble follows.

The latest version of Ubuntu (8.04 or "Hardy Heron") came out on Thursday. I suppose the difficulty of downloading updates when a new version is released is a testimony to Ubuntu's growing popularity. This time, I couldn't get through the download. It took about three hours to get a third of the way done, and then it stopped. What's more, I couldn't re-connect, so I had to wait. But in my Googling, I found out that you can download the alternate install CD, mount it as though you've burned it to a CD, and use that to upgrade. So I tried downloading the CD. It was just as slow, if not slower, until it timed out.

By that time, a number of other mirrors had come online, so I was able to choose one that was a lot closer (and less overloaded). I downloaded the CD image from Georgia Tech at a rate of 4 MB/s. Yes, four megabytes per second! The 700 MB download was done in a few minutes. (I'm going to miss having a university Internet connection, but I wouldn't have had to resort to such drastic measures if they allowed BitTorrent traffic in the dorms.)

After mounting the CD image (sudo mount -o loop ubuntu-8.04-alternate-i386.iso /mnt/) and running the upgrade utility (gksudo "sh /mnt/cdromupgrade"), I was good to go. Or so I thought. Apparently you still need to connect to a server to verify the upgrades or something like that. Since I couldn't connect to the servers at all, it wouldn't work. But then I thought of going to System -> Administration -> Software Sources and choosing a different mirror. I let the system choose the fastest one to me, but it didn't seem to be working well. Russia? Belgium? I couldn't connect to either of them. I tried a third time. Georgia Tech. Aha.

Now that the upgrades could be authenticated or whatever had to be done, the upgrade went smoothly. After the reboot, I surveyed the virtual territory. There were the inevitable annoyances. For one, my default system font (DejaVu Sans Condensed) was uninstalled, but it was no problem to reinstall the ttf-dejavu-extra package. Another annoyance was that I would get a system beep whenever the computer booted up. I managed to turn this off by adding the line blacklist pcspkr to /etc/modprobe.d/blacklist. I've also noticed a couple of times that the bootup process gets to a plain black screen and stops with no hard drive activity. A perusal of the system log suggests that this is a network problem.

The main issue (unless I'm forgetting one) is that I couldn't have two applications using the sound card at the same time. If I were listening to music in Rhythmbox and I paused it to watch a YouTube video in Firefox, I wouldn't get any sound from the video. After some digging, I found that installing libflashsupport fixed this problem, but I still couldn't use Audacity if another application was playing sound. A friendly person from the Ubuntu Forums suggested I install libasound2-plugins. After doing that (and rebooting, just for kicks), I would be able to use OSS with PulseAudio, which is new in Hardy. So I set Audacity to use OSS, and when I run Audacity with padsp audacity, as suggested in the forums, it won't want to have the sound card all to itself. Problem solved... mostly. This doesn't work for Ekiga because I can only set Ekiga to use ALSA, not OSS, but it's a start. I haven't used Ekiga much lately anyway.

(Standard disclaimer: I don't know that much about computers. I learned the above information by searching the Internet and asking people.)

The Ubuntu developers made a pretty controversial decision when they decided to make Firefox 3 Beta 5 the default browser in Gutsy. Beta software in a release that's touted to be especially stable? It doesn't add up. I did my homework and found that some of my favorite extensions wouldn't be compatible, so I made a copy of my Firefox profile folder (~./mozilla/) before upgrading. It's a good thing, too. While Firefox 3 did seem to use less RAM, I noticed that it almost froze a few times. It did have some cool features, like the new location bar with its frecency algorithm, the new download manager, and the ability to zoom in and out of entire pages like IE 7 (I think). But the lack of useful extensions was the show-stopper for me. I uninstalled Firefox 3, reinstalled Firefox 2, replaced my profile folder with the copy, and all is well again.

Except for the fonts. Now in Hardy, Firefox equates displays the clones of Times New Roman and Helvetica/Arial whenever those fonts are called for. Previously, it would just show the default serif and sans-serif fonts (DejaVu Serif and DejaVu Sans), which I think happen to look better. They scale better, for one, and I think they better suited for the screen. I don't think this font thing is specific to Firefox, and I don't know to change it, but I've changed this site's stylesheet so DejaVu Sans precedes Arial. It shouldn't make a difference to anybody except certain Linux users (or anyone else who has DejaVu Sans?), but if it has caused the sky to fall on your head, please let me know.

So, what's actually new in Hardy? Updated versions of all (well, most of) my favorite programs, like Rhythmbox music player, Pidgin instant messenger, the GIMP image editor, and the OpenOffice.org office suite. Some of the more basic default programs have been replaced with more sophisticated ones; the BitTorrent client and the CD burner come to mind. Plus, this new Tracker search tool seems pretty handy although I haven't needed to use it yet. I'll probably discover more new and exciting additions as I continue to use the operating system.

Wikipedia has a list of pigs, although it also includes hogs and wild boars.

For your entertainment, here's a slow-motion video of a tomato in a blender.

And here are some cool photos of striped icebergs that apparently look like some British candy. I wouldn't want to eat one, though.
