C'mon. Everyone is bitching about DST. Let's really just admit time is an illusion* and embrace it! I say we just insert an extra hour every weekend (and never "give it back"). I also propose a single timezone for the whole world and using a 10 hour day (metric time). But I'll settle for an hour inserted every weekend.
We've been discussing this at my campus, and one major argument for requiring laptops is that then students could use some loans with tight restrictions on what can be purchased (maybe Pell grants? I don't know the specifics)--ie only required materials. So if the university requires laptops, then perhaps students who would not otherwise get the laptops could. The issue regarding if it is appropriate to increase student dependence on student loans is a whole 'nother one...
What?! Do you consider a telescope something other than a sensor? I suppose it could be seen as a tool for keeping astronomers up at night. Or a way of transferring money from the general public to scientists. Um.. But I definitely consider a telescope to be a sensor.
I expect to see at least a Chapter (maybe a Master's thesis?) on the feedback between RIAA actions, slashdot reports, and increased usage of "bad software" (i2hub in this case?) because of the publicity.
I was chasing storms in a plane as part of a research project to study sprites, jets, and other middle-atmosphere lightning. Our plane got into the upper region of a small storm, and we were hit by lightning. We had video cameras going and they didn't even hiccup. Check out a frame grab (the next frame was completely saturated). That pod in the image is the end of our wing (I think this was the Westwind II, but it may have been the Jet Commander).
Another amazing video is of a plane getting hit by lightning at a Japanese airport--check it here.
Bottom line: planes can be just like a big hydrometeor from lightning's perspective.
Actually, LEO geosyncs are very easy. Everyone has one. In fact, most of the time, everyone is in a LEO (very LEO) geosync orbit. (mostly, hopefully we all move around in the orbit a bit). LEO geosync has very low launch costs--to get to the local elevation of ground. Or don't. Even if you stay in bed, you'll keep circling the earth once per day, locked in step with the globe as it goes around. The field of view isn't that large, but it keeps me entertained.
I guess we all have a small amount of propellent we fire off every now and then, but for the most part, it is a pretty easy orbit to maintain.
Don't worry chicken little, with the Leonids you are really quite safe.
For the Leonids (which is the subject of the article, after all), even a large meteor will burn up in the atmosphere. The Leonid entry velocity is 70 km/s. Because the composition is mostly ice, meaning the Leonids have a lower density (approx. 1) than a typical meteor, and because of the high velocity, the Leonids burn up very quickly (relative to a "typical meteor"). The Leonids maintain a nearly constant velocity as they enter the atmosphere, and nearly any size Leonid will burn up by ~85 km altitude at the lowest. A more typical meteor, moving at 20 km/s with a density of approx. 3 will both slow down as it passes through the atmosphere (if large enough, it will slow down to the terminal velocity of any body falling in the atmosphere, and basically be in "free fall"). And for a typical meteor, 100 metric tons at "source" will be 1 kg on the ground.
I'm really a homebrewer, I just play a scientist at work.

will we see a day when their stock MP3 player won't play "non-secure" music?
I saw the day about two months ago, and it really bummed me out. I hope someone can correct me, but the very attractive (except for the Magic Gate) MP3 player by Sony (the NW-MS9)
requires the magic gate memory stick and software which only works in Windows (possibly Mac OS?). I have the Sony Vaio Picture book with a memory stick slot, and the Sony PC-3 camera which uses the memory sticks. I love the memory sticks, they work fine under Linux. And I would love to be able to just slap mp3s on the memory stick and throw them in the Sony NW-MS9--it is exactly what I want in an MP3 player. No stupid cables to find/carry around. Tiny, tiny, tiny.
If anyone can (truthfully..) tell me that the NW-MS9 will play mp3s on a non-magic gate memory stick, I'd order one today.
But alas, the day has come, Sony is attempt to force me to accept digital rights/wrongs that I don't won't. When will the companies remember--"the customer is always right"?
The current Linux codebase is good, but for it to be great, the developers must stop patting eachother on the back...
Glad to hear that you are going to do the rewrite. The source is all there. Are you setting up your efforts on sourceforge or will you just announce it view usenet ala Linus?
Are you using 2.4.X? I believe that 4 GB limit on Intel HW is long gone (the 2.4.1 menuconfig help describes using the Intel Physical Address Extension (PAE, implemented on Pentium Pros and better) for up to 64 GB RAM, but I couldn't swear that it works:
my big problem is a motherboard with only 8 DIMM slots and it only claims to handle up to 512MB DIMMS, so that's the 4GB limit I'm up against. Maybe I'll just pop in a 1GB DIMM and see if the mb likes it.

That's a lame comment. Here's a little more intelligent take on the Gore/Internet thing than the bash-Gore spin that's playing so much more these days:
The HIPAS observatory operated near Fairbanks AK by UCLA has had a 2.7 m mercury telescope operating as part of their LIDAR system for well over a year (I couldn't find a first light date easily, so that's a very conservative number--I think it's been two or three years at least). Sure a 6m 'scope will be sweet. But if/. is going to start updating me with every new larger telescope that comes out...

How about a pointer to the Forth port of Pong for OpenFirmware? I'd give that a shot.
I'd be in heaven! I'd also be willing to help. I've been using slackware a long while, and just got a new G3 notebook. I'm not excited about any of the RH-derived ppc distros, and even took a look at Suse and *BSD--both seemed to advertise ppc support, but I couldn't find the download, order a ppc CD, or locate installation hints for the G3 laptop anywhere.
Any pointers to slackware/ppc would be appreciated!
Combine a FDF from TRW (only URL I could find a few months ago was http://www.isrec.isb-sib.ch/paracel/FD F.html, about its use for pattern matching in DNA/RNA/protein sequence analysis. Couple that w/ SAIC's "In Flight Recorder" (sorry no URL handy)--a real time OC-48 data capture box.
We need FDF/In Flight Recorders, lots of FDF/In Flight Recorders..
Worse than a lack of knowledge of multiprocessing, it represents the very sloppy use of (lack of understanding of?) units. MHz tells you how many times a second something happens. If you've got one soundcard sampling at 44.1 MHz, and you slap a second one in, and start advertising that you can do sampling at 88.2 MHz--you're wrong! You can now record twice as many 44.1 MHz audio streams, but you can't record at twice the sampling rate.
You could slave the two soundcards together under a master sync, write the code to make it look like a single sound card, and have a single input... (but this gets into the poster's comment about lack of SMP understanding).
To finish this analogy: take one of your dual Celeron boxes, cat/proc/cpuinfo. Do you see one CPU 2Xspeed or two CPUs at the 1X speed? (I know you can just edit the source... So does _everything_ on the box see a single processor at 2X or two processors? This is where the SMP knowledge comes in again.)
I've got an SMP box which really rocks compared to a single processor box of 2X the speed--it does mail/web/services ~5 users simultaneously (not just "pine"-users either.. matlab, gimp, netscape, emacs type-users. So my experience is that SMP boxes are great for many processes (unless you want to run just one thing like rc5--and then it is still running processes for each processor! compare this w/ the soundcard analogy above.)
I've been wanting to rip audio from SCSI connected DAT drive under Linux for quite some time, and finally it comes up on/. Thanks for the info so far!
So I have a few questions yet: I've found a Python Archive 4324RP for $285 from DriveStock (any better vendors to recommend?). I've got an Adaptec 2940 SCSI controller. Would I be good to rip w/ this configuration? The DATlib README says something about "'esp' or 'fas' hardware and with audio-firmware." What does this mean? (Or more importantly, does the Python 4324RP/Adaptec 2940 satisfy this requirement? It looks like esp/fas is only needed for fastforwarding the audio DAT anyway (non-crucial). Is this true?
It appears I really need to carefully ask for the audio firmware. Anyone been shipped a Python w/o the audio firmware and had to hassle to get it?
Is there a pointer to a DATlib README.linux (looks like what they've got is still fairly Sun specific, but not horribly hard to do under Linux). If there's linux specific documentation, that'd be great. If not, I hope to have my experiences written up in about a month!

That's a lame comment. Here's a little more intelligent take on the Gore/Internet thing than the bash-Gore spin that's playing so much more these days:
True, Mr. Gore didn't invent the Internet - but then, he never said he had. What he did say was, "During my service in the United States Congress, I took the initiative in creating the Internet." That was a deeply unfortunate sentence - but what makes it so unfortunate is that now it is impossible for Mr. Gore to get the credit he actually deserves. Declan McCullagh, the Wired writer who first played up Mr. Gore's remark, puts it this way: the vice president "was one of the first politicians to realize that those bearded, bespectacled researchers were busy crafting something that could, just maybe, become pretty important."
Gore probably did more than you and Bush combined towards getting the internet as widespread today as it is.

"In their struggle for the ethical good, teachers of religion must have the stature to give up the doctrine of a personal God."
I highly recommend the Sept 1999 Sci. Am. article (page 88-93) "Scientists and Religion in America."

"A dog might as well speculate on the mind of Newton. Let each man hope and believe what he can."
A great topic to struggle with, but ya might as well go for a BA in philosophy instead of just some karma on
