Well, well, well. I was disappointed in the US Presidential debates. Only 2 candidates. Sheesh.

There was a small rally on campus for Nader, which I participated in. We got about 75 people. Not huge, but decent. There were a few reporters (at least one each for newspaper, radio, and TV), but I haven't seen much coverage yet [picture]. There have been polls saying that about 75% of the public thinks that adding a third candidate would have made the debates more interesting. I understand that Dan Rather essentially called last night's debates a snorefest...

Anyway, on to some non-political stuff. For one of my CSci classes, I (along with a group) have to write some simple malloc() and free() routines. It was really funny how we did most of the development -- Borland Turbo C++ version 3.0 for DOS. DOS does not have sbrk(). DOS does not have 32-bit pointers. Anyway, we moved the files over to a Unix box to finish things up. We got them to compile, and a test program appeared to not crash, so maybe it actually works. At any rate, we still have to put in some code for checking for overruns and underruns (we have special buffers that contain a particular pattern. If the pattern fails somehow, we know that there was a problem). Hopefully we'll get it done by the due date and time (midnight on Thursday).

Well, I haven't been keeping up with this. Being sick for a month doesn't help things.. Oh well, I'll have to see if I can get back on this horse.

I totally screwed up a CSci assignment today. I was supposed to download a Word(!) document, fill in relevant parts, and hand it in.. Oh well, it's still early in the year, and I still have plenty of time to make up for stupid mistakes. Hopefully, I'm done with stupid mistakes for this semester.

I don't know what it is, but school really seems to take a lot out of me. Even if I don't do anything (or maybe it's because I don't do anything), I get really tired. I should really get into an exercise routine (heh, like that'll happen).

The exciting event over the weekend was that Ralph Nader had a fairly large rally here on Friday. I paid my $7 to get in. Apparently, 12000 people is (or was as of Friday, they're still having rallies) the largest gathering of individuals paying to listen to a Presidential candidate. Not that it means we gave a whole lot of money -- they got about $110k (entry cost plus donations once in the door). Still, it's a much better deal for me than those $25k/plate dinners that some candidates have (*cough* *cough*).

Anyway, I'm having all sorts of fun bashing Sun here at work. We can't figure out how to use the 100Base-T network card in our new server. Fun. My boss had hooked up our tape drive to the system without realizing it only ran at 10Mb. Our backups are running several times slower these days.

As always, I keep hoping that I'll get motivated to help out on some open source projects. Someday it'll happen..

Found out about a semi-new TV channel in town, KSTC 45. There have been all of these strange `Hi, I'm Gregory and I'm 45' posters and ads all over town. It's kind of neat, as it is supposed to be an independent station with a local focus. Unfortunately, they're owned by Hubbard Broadcasting, a company that owns about 10 stations (and they at least used to have a DBS network). It's just hard to call a station like that `independent' (of course, they mean that it will not have a network affiliation

I'm sick. This sucks. I was just getting over another illness when this one came along. I could barely function yesterday, and I seem to be doing a little better today. We'll have to see how things go.. Anyway, I've been as inactive as possible, trying to let my immune system do its thing.

I was happy a few days ago when I whipped up a little phono jack switch. One input to two different outputs. Not that it was very hard to do or anything. Now I just have to do some soldering and put it in a small box..

Well, I see I haven't posted for quite a while. I've been busy with Marching Band and the first week of classes. My apartment is now fully populated (4 people), though we are still in the process of setting everything up. We've got a nice stereo system going (really good receiver with Dolby Digital), and have two computers hooked up to it. I still have to find a good way to get MP3s playing, though. Both computers are not very close to the stereo itself -- you have to get up and wander over somewhere to change the playlist or anything. Oh well.

I had been working on a simple MP3 server web interface, though I don't know if that will ever bear fruit. I'll probably just use RIMPS or a similar piece of software.

I'm having some trouble adjusting to the fact that my computer is not in my bedroom this year. While it's nice to fall asleep without the background noise of my computer, it's annoying because I haven't been able to keep up with my e-mail very well. I unsubscribed from some LiViD mailing lists that I'd been on for a long time, but I got tired of wading through messages that weren't very interesting to me..

Anyway, people I know will just have to deal with the fact that I will not respond as quickly as I usually do..

Wow claudio. That's kind of a scary picture. I'm not exactly sure what kind I am. I try to avoid non-free software (Netscape is my big exception right now), I like point-and-click, though I understand (and use) the power of the command line (well, don't forget the fact that all graphical file managers for Linux are currently crap). I'm running bash2, and I'm a .tar.gz or .tar.bz2 person.

As for my xterms, I run with reverse-video white on black, and with ls aliased to ls --color=tty -F. I've also hacked up my own /etc/DIR_COLORS file. I remember some point a year or so ago when someone jokingly made `ls.themes.org'. I thought that was a great idea ;-)

In the area of documentation, I like it when programs are completely intuitive, or if they at least have some decent usage information when started with --help. However, I hate it when I want to look at the more advanced parts of programs, but I can't because of inadequate docs in /usr/doc or the man pages. I also hate info pages, unless I'm viewing them through gnome-help-browser.

Anyway, I'm having all sorts of trouble with this fraud detection box. Well, that's making it sound really bad. It was actually a pretty easy install. Unfortunately, the IP address it is using has been administratively blocked on one of the routers to the outside world. Getting that fixed has been pretty difficult. I do have it running on two different IPs right now, so at least it can be accessed. However, the DNS entry doesn't point to the publically accessible address. Oh well.

Hmm. `publicly' and `publically' are both correct spellings, according to M-W..

Afternoon

krftkndl: I, too, have heard the call of `just write another one,' and rejected it. However, I think there really are enough people pissed off about the current state of text editors that they would love to do that. But I just can't help thinking that someone has already made the editor I really, really want..

In the meantime, I'm counting down the minutes until I leave today. I'm not coming into work again until school starts (~10 days). I'm going to be really busy for the next week and a half...

Late

``We will bury you,'' or something to that effect: LinuxToday links to the story. Does this mean I gotta boycott Sony? Dammit...

Went home for a little bit. Tried to go to an `all-school' reunion, which was really dull as I was probably the youngest person there (most people there graduated in the 50's, 60's and 70's, I think). Oh well, got some decent food.

We have this research box at work. I was told that it was for `fraud detection', which I thought meant that it was some sort of honeypot box for detecting crackers (or at least script kiddies). I completely forgot that there is such a thing as financial fraud, which is what the box is for. Makes sense, as the box is in the business school.

Anyway, the main guy that actually uses this box for doing research is apparently back from summer vacation or something. He tried accessing it, but couldn't because there is a rule somewhere on one of our routers blocking that IP (I get `!X's when doing traceroutes from the box). Of course, nobody wants to take the blame/responsibility for it, and I couldn't get the block removed (well, the main networking people said it wasn't their problem, and the guys here say that they didn't do anything either). Changed the IP address, and now we have to see if the DNS entry can be changed..

I hope I will be able to do some more fiddling with radar data, though I don't know if I will be able to do anything this week (Marching Band starts on Thursday), and I don't even know what their schedule is for producing unencrypted data. I might just have to wait until the end of next month.

Evening

Well, it turns out that the central networking people foobared -- they actually were blocking the above-mentioned system. I guess it got broken into a month ago. I'll have to see if I can pull down a [rd]ecent Linux ISO of some kind to do a reinstall. Maybe Mandrake..

I had to try and figure out how to back up the system in a reasonable manner. tar is supposed to support running over some sort of remote shell, but none of the commands I tried would work. In theory, you should be able to do something like `tar cvIf user@host:/path/to/archive.tar.bz2 /path/to/archive', which would be really cool, IMHO.

I ended up riding my bike out to a theater in a nearby suburb in order to watch The Cell. It was both cool and not. Like with many movies, I'd already seen many of the best visuals in the ads, which was disappointing. Also, you could tell that Jennifer Lopez was trying to hide her accent, which was just annoying..

I remember that I had read too many reviews of The Matrix before seeing it, which spoiled much of the experience. It was still a cool movie, but I wasn't as surprised by what happened as everyone else was.

Seen on the web: LAPD Harassed Philly Mayor's Aide. ``We don't treat our guests in Philadelphia this way,'' the Mayor said. A lot of people would disagree.

I'm wondering if/when Kuro5hin will be resurrected. It was an interesting site.

There are a lot of different methods for distributing news and information popping up on the Internet. You have the traditional media, where the editors tell reporters what to do. You have places like Slashdot, where individuals tell editors about interesting things they've seen. Then there are places like Kuro5hin, where news is moderated before being released to everyone. Advogato requires a certain level of trust for people to be able to post news. The Independent Media Centers largely have an open policy where basically anyone can post.

In my opinion, a combination of these techniques is required. Certain reporters could gain trust and basically post whatever they want. People who are less trusted probably need to go through at least a thin layer of moderation and filtering. Perhaps everything should go through a kuro5hin-style moderation. Then again, it may be hard for the trust levels to work appropriately. For instance, if you have a general news site that suddenly starts getting input from a well-known reporter from a well-known newspaper, would they instantly become trusted and able to post anything? I suppose it depends on the audience.

If the readers get much of their news from corporate media outlets, they'd probably mark the reporter much higer than if the readers were more interested in the independent media.

Just some random thoughts..

I shouldn't have, but I wrote something to Fred Moody. Cripes. The guy has `sources' that span a continent of hatreds. NT guys that hate Linux. BSD guys that hate Linux. Security guys that say having source code is a risk. Guys that say having source is a good thing. He has managed to make just about the most self-contradictory article ever. Is he insane? Well, I wouldn't blame him for going a little nuts after having to read what many /. trolls sent him, but this goes above and beyond...

Anyway, I shouldn't waste my diary entry on that.

schoen: Yeah, I felt pretty much like that. Didn't get much work done today after seeing that. I was hoping for a good outcome, but the judge couldn't or wouldn't try to test the Constitutionality of it. It'll pretty much go to the Supremes whether we like it or not. Hopefully, the MPAA won't try to completely stall the case (though I expect they will).

On the radar data front, I have been slowly digging up information about data formats. There's a bit here and here. I'm not sure if the data available over FTP is currently being encrypted or not. Apparently, they have designated times when it is not encrypted to facilitate testing of software. The encryption will be removed once everyone is able to receive over FTP or some sort of multicast. There's an older system called NIDS that has to be phased out before everything can be publically available.. Kind of strange. The RSL system apparently can't decode the products that NOAA is currently releasing, and I don't know if it ever will -- it seems to understand a more raw form of data.

Anyway, I hope I'll be able to find some software to decode the stuff that will be available over FTP. Either that, or I'll just have to keep hunting for decent documentation about the file formats...

Afternoon

Grr. I wish Mapquest had an option for making biker-friendly maps and directions. It should basically ignore interstate highways (which are illegal to bike on, unless you have a permit or something), and add bike trails.

I want to go see The Cell tonight. I am still pissed about the MPAA-DeCSS debacle, but I'm in need of some mind-bending.

gtaylor: I've actually been using METAR data as the source for weather info on my home page for quite a while using a modified METAR Perl module. The version I use is laying around on my website somewhere..

At any rate, I seem to be able to retrieve NEXRAD radar data via FTP (wget works, though interactive clients (Netscape, ncftp, etc) can't handle it for some reason). I went looking around and found that the good folks at Goddard Space Flight Center have made some software available (much of it is GPLed) that can render radar data. Still working out some bugs..

In this process, I discovered that my fairly new ReiserFS /usr partition had been (slightly) corrupted. /usr/src/linux/include/asm/param.h had suddenly turned into a binary file, and all attempts to remove it would produce kernel panics and deadlocked processes. Fun. Even better -- reiserfsck wouldn't compile on my system (signal 11). Oh fun. Fortunately, I got it to compile on another box, and ran reiserfsck --rebuild-tree, which scared me a lot with it's warnings of it only being a beta-quality option.

In the end, it appears that all has turned out well, though I think there are a few files missing from that partition (param.h, for example). At some point, I'll have to try and run a RPM verify job, make sure that there aren't huge problems..

Anyway, I'll have to do some debugging with the radar package I downloaded. I think I may be missing a package. Shouldn't configure catch that?

I've always wondered if someone `famous' used Linux. Someone you'd know from TV or movies.

Also, I wonder why women don't seem to get into Linux or `the community'. Girls are usually a lot more social than guys, so it would seem that this is a really screwed up world we all live in. Then again, the girls I know are highly susceptible to gossip, which can easily destroy social circles..

Hmm. I used `girls' instead of `women'. Blah, I'm not feeling PC today.

Anyway, I'm currently trying to do some wacky NFS sharing that is going to involve mounting loopback filesystems and other weird nonsense. There's probably another solution which is easier, but I haven't found that one yet.

Evening

Well, the loopback filesystem trick actually works (the problem was that the disk being shared didn't have enough space left, and it was supposed to be pretty much an exact mirror of another system. Symlinks to another filesystem don't work all that well with NFS, but maybe I could have still found a way..). Never thought I'd find a real use for loopback devices (other than viewing ISOs that haven't been burned and whatnot..). Then again, I guess a loopback fs is an important part of those bootable business cards, among other things.

Spent much of the afternoon mucking with TCP Wrappers on Solaris. Some of the daemons just don't want to run from tcpd.. Annoying..

I see that there are versions of tcpd that support IPv6. Might be fun to play with.. I've been interested in IPv6 for a long time, but it's only now really getting any use on the Internet at large. Debian 2.2 supports it though. Hopefully it will finally start to displace IPv4.

Kind of along the lines of why we need IPv6, I'm always scared by the DSL and Cable modem setups where you essentially get 25% efficiency WRT addresses. The lower number is the network number, the higher is the broadcast. The two left over are gateway and client IP. Scary..

And this brings me to a question I've had for a long time -- is there a system for NAT in IPv6? Ideally, this won't be necessary, but we all know that the service providers will only want to give you a single address if at all possible, meaning that they can bilk you for cash if you want more than one computer on your connection..

Annoying companies..

Late

It's raining, and I'm getting interested in how Free Software can be used to distribute weather information. There's a system called EMWIN that I've looked at before, but I don't have the time/money/hardware to play with it. The best way to get info right now is probably to have a satellite downlink. They have a moderately powerful transmitter up there, so the dishes only have to be 2-3 ft in diameter. Not as small as the digital satellite TV dishes, but not exactly huge.

The important thing is that you can get real-time or at least close-to-real-time data, which is often better than what you can say for most of the current Internet sources. With EMWIN, you can get notified of watches and warnings at the same time as or earlier than your local TV and radio stations. Weatherguys.com is largely powered by EMWIN data.

At any rate, I have been wondering if the National Weather Service will make at least some radar data publically available on the Internet after some contracts expire at the end of next month. It looks like they have defined the layout for how things will be on their FTP server. This sort of thing is a prime candidate for mirroring and multicasting.
