adenied wrote to let us know that on Dec 16, NASA successfully launched the Terra Earth Observing System (EOS). This particular satellite is the going to be the flagship of the new EOS system. With this, and other satellites doing similar work, NASA will continue to study the Earth, which has been some of their best work recently.Update: 12/20 08:18 by H :Thanks to Dennis Gerasimov of NASA for clearing up some of the details - click below to learn more.

I would like to point out a mistake in article http://slashdot.org/articles/99/12/18/2340212.shtml about Terra satellite. Terra is not a flagship of EOS program. Terra is the first mission that will be fully integrated into EOS program. The flagship satellite TRMM (Tropical Rainfall Measuring Mission) was launched by NASA together with NASDA (Japan) on November 27, 1997. The satellite is still operational and collects data. More info can be found at http://trmm.gsfc.nasa.gov and the resulting data is located at TSDIS project (the ground data processing system for TRMM) at http://tsdis.gsfc.nasa.gov.

Kevin Remhof has submitted us a piece on an area of Linux that a lot of you might not be familiar with, but may wish to be: Linux and X-Ray Astronomy. Talks about some of the things you can do, as well as common applications to do them with. Check it out. The following was written by Slashdot Reader Kevin Linux and X-Ray Astronomy

by Kevin Remhof

On July 23, 1999, NASA deployed the Chandra X-Ray observatory from the Space Shuttle Columbia. This telescope is a major leap forward in X-Ray astronomy. It will enable scientists to study dark matter, black holes, and other objects with great detail. I was checking out the information on the Chandra website and started to wonder about the software behind this telescope. So, I did a little searching on NASA'as website and found some interesting information. What I found is that X-Ray Astronomy is depending more and more on Linux for analyzing the data.

Background

X-Ray astronomy has been around since the early days of the space program. X-Ray telescopes work much the same as a regular telescope, but rely on X-Rays to view objects. The earth?s atmosphere absorbs most radiation from space. So, in order to use these telescopes, they have to be lifted out of earth?s atmosphere. The first X-Ray telescope sent into space took pictures of the Sun. Since the Sun is so close to earth, it was not hard to focus this crude telescope. Modern X-Ray telescopes are much more refined. The Chandra telescope could read the letters on a stop sign from 12 miles away.

X-Ray telescope data needs to be decoded before it is useful. This is similar to the concepts behind the SETI@Home project. Astronomers are allocated time to use the telescope. Chandra has about a 55 minute viewing time during each or bit around the earth. The telescope first gathers data without interpreting it. That data is then transferred to earth. Scientists then pick up chunks of that data for analysis. It is then that the power of X-Ray telescopes can be seen. X-Ray pictures are a little strange. Although attractive pieces of art, they are not easily understood by the general public.

The Linux Connection

Astronomers have used UNIX as their standard platform for years. Sun, HP, DE C/OSF were all commonplace. That is until Linux came along. Linux is becoming more and more popular and is threatening to take over as the platform of choice. Linux is now the darling of NASA. It is easy to powerful, easy to use, and porting applications from UNIX is not too difficult. NASA even uses Beowulf clusters for various projects which need large amounts of computing power.

Linux is a great choice for X-Ray astronomy because of the wide available of the OS and the software for it. Two popular programs are XANADU and FTOOLS. Both of them began as UNIX programs and have now been ported to Linux.

One astronomer, Ken Ebisawa has even written a HOWTO on "Linux for X-Ray Astronomers ". He details how to get Linux up and running and some of the various tools useful in X-Ray astronomy. According to the Goddard Space Center?s website, & quot;Ebisawa hopes to resolve the mystery of the Milky Way's so-called diffuse X-ray emission, a ubiquitous cloud of X-rays that blankets our galactic plane and whose origin is unknown. To do so, Dr. Ebisawa will look at a region of space where this cloud varies in X-ray brightness but where there seems to be no distinct energy sources to produce it." Ebisawa will use his Dell Inspiron laptop to analyze his data.

Open Source Software

The latest development in X-Ray astronomy is Open Source. Another program for analyzing X-Ray data is called SAOimage. Currently, it is being redesigned and updated using Open Source practices. Open Source is a natural for this because users often want to extend the software by combining it with other systems to come up with a research environment. It also helps to reduce some of the costs associated with development of such complex systems. Using the bazaar model of software development allows multiple developers to maintain and upgrade this complex code. It also allows the shared development of key pieces of code and functionality while satisfying individual needs of users.

Conclusion

Linux is rapidly becoming the OS of choice for X-Ray astronomers. This is yet another credit to the flexibility and power of Linux. More information on the Chandra scientists can be found here.

Miguel de Icaza writes "The people that did the MOSIX cluster system have now made a port for Linux. But they do not provide all the source code of their work. They only provide a binary kernel module which allows the user to run only a cluster of six machines(they show a picture of their 100 cluster node). The binary module requires kernel modifications. (Thus breaking the Linus permission for binary modules). I think we should stand up against this blatant violation of the GPL. " Update: 02/27 11:34 by S : In related news, xose points out other license violations: Linux Network Drivers states "Several drivers have been distributed that are little more than renamed versions of my drivers. Some have my name, the copyright notice or the Gnu GPL license notice removed. The less flagrant violations merely fail to note that the driver has been modified from the original version. (The GPL requires such a note.)" Update: 02/27 11:05 by S : To clarify Miguel's point: Source must be available for any addition to a GPL'd product. Linus and the other core kernel developers gave a special dispensation to allow binary modules to be inserted into the kernel as long as they do not require kernel modifications of their own.

Some posters argue that this is whining, and we should be grateful for more software on Linux. Others argue Linux must let go of its licensing conditions to succeed. Neither argument is relevant. MOSIX is violating the Linux license: it is a binary kernel module that requires kernel modifications. Just as Microsoft would not tolerate violations of its license, the authors of Linux need not tolerate this violation. The fact Linux is available at no cost is irrelevant: the license is based on copyright law and Linux is not in the public domain.

Other posters believe that Mosix could fork the Linux code base and do what they want. This is incorrect. The license terms are determined by all the authors (copyright holders) of a product. Unless Linus and co agreed to change the license it would not change, fork or no fork.

If it is true that the Israeli government does not allow the source of the Mosix kernel module to be made available, it is my understanding that the GPL states that the Hebrew University may NOT distribute Mosix to anyone.

NASA has flirted on and off again with the notion of a manned mission to Mars. It appears again that this may be a reality, with JPL physicist Mark Adler pushing ahead on this. Interesting stuff to read-and hopefully they won't make the same network mistake as the space station did.

When I put out my call for Geek Christmas Gift ideas, I had no idea what I was in for. But after the storm of email that followed was washed away, I was left with a list of toys that any geek would be excited to give or get this year for whatever holiday it is you celebrate this time of year. Hit the link below and read the list if you're curious. Random Stuff There were a few things that were suggested, that, well, I bet Santa won't come through for them. Hemos asks for Nanites. Thats all he wants. Nanites. Somebody smack him. Nima Negahban says "I would like the beowolf cluster avalon for christmas, dont worry about it fitting it under the tree. " david yates wrote in and simply said "Half naked Princess Leia ,as Jabba's prisoner, action figure." I'm sure his mother is proud. He can have the Action Figure, I want 1976 Carrie Fisher. Games Everyone and their brother wrote in to say that Nintendo 64's and Playstations are great. And the game of choice is definitely Zelda 64. I second that motion. I suggested it to my dad as a Christmas Present. Terrible idea- now I gotta wait until xmas to find out if he got it, and if he *didn't* I gotta buy in on Dec 26. Hard as hell to find. Folks suggested other things like the original Kings Quest or Leisure Suit Larry. Prince of Persia. Commander Keen. Ultima. All those games that aren't around any more, but with their original packaging. Finding a 5.25" drive to play them with might be a tad tricky tho. Clothing It's a well known fact that its better to be clothed at least part of the time. And no self respecting geek should be without a vast array of appropriately political t-shirts to pad out your closet full of suits, jackets, and ties (cough). Daniel suggested checking out the Free BSD Mall for BSD clothing. Jonathan Moore suggested the ever popular KMFMS t-shirts for your local microsoft hater. If thats a bit to exotic for you, how about the classic that Doug Boettcher sent us: the Hack Naked shirt. Since we're mentioning all these t-shirts, we ought to mention that CopyLeft has several shirts including my Don't Fear the Penguins ones, and Slashdot ones too. Software Several folks wrote in to say that they were buying Linux CDs from any of the various places that sell them, and giving them away to the needy. I tend towards Linux Central, and in addition to them Cheap Bytes OpenBsd.org and The Linux Mall were all suggested as places where you can buy the stuff we like. Hardware By far the largest catagory for gift ideas was of course Hardware:The Gift that Costs to much. Of course, anyone would want a a Palm III- it's hard to think of a better stocking stuffer. And besides, they're practically money in the bank now that you can use them to collect automobiles of the rich and famous. But if you've already got a Pilot, James A. Hillyerd suggests a GoType keyboard as the perfect accessory. If the pilot isn't your bag, but you want to read on the road, Mahlen Morris suggested A Rocket E-Book which is basically a tablet computer that is designed to replace books You can get them here. And apparently they have some sort of deal with Barnes & Nobles so you can get content to read on it. They're pretty sweet looking- someday we'll have a wireless version with net access, then we can forget paper. But for now, this'll do.

Have trouble remembering passwords? Digital Persona sells sweet hardware that that you can use to do finger print identification. Suggested by Andrew Lepisto. The pdQ was suggested by Adam D. McKenna. Its a cel phone with an integrated Pilot. Another fairly common suggestion for geek gifts was cel service from your local provider, and a cel modem for the laptop equipped gift getter. Sean McPherson suggested a Kodak DC210+ digital camera. Saves big bucks on film, and is supposed to be supported by SANE. I'm actually planning on getting a Digital Camera before the upcoming string of conferences, and I'll probably look at this one (unless Santa already has one in his bag for me, although at $400 a pop, I highly doubt it) Steven McDonald suggests that we look at DVD RAM Drives as a new huge backup device for storing your MP3s and Porn. Oh, and legit data too.

Mike Miller sent us several suggestions including the Happy Hacking Keyboard. I played with one at ALS- they're not bad. Just as cool are the new Color Gamesboys. I suppose tetris wouldn't be vastly improved by color, but its still pretty sweet. For those with a hugeass budget, How about your very own Alpha Cluster? Obviously Jakob is a lot more hopeful for Saint Nick than I am this year *grin*. How about a vt320 Terminal? Daniel Morrison suggested it, and I think it sounds pretty cool. I had a terminal attached to one of my Linux boxes for awhile. I Let it tail log files and stuff. Kinda fun for reading documentation and stuff too. Can't afford a Multi-Head X-Server, video card, and spare monitor anyway. Plus you can run them into another room and check your email from your kitchen/dining room/bathroom.

Matthew J. Allen sent us a pricey one, but its oh so sweet: Remember those Huge Flat LCD Screens from SGI? I sure do. I wake up after erotic dreams about them. (SUBLIMINAL MESSAGE:Hey SGI: Give Rob one of those things for banner ads. You've got a spare one just sitting around, right?). Matthew also suggested an Iomega Clik Drive if you're on a more reasonable budget. Those things do look pretty sweet. Do cables piss you off? How about the gift of a tangle free workspace? Scott Donovan sent us a link to Cordless Mice and Keyboards from Logitech that will free you up for spinning on your swivel chair really fast until you fall over from getting dizzy instead of getting tangled up in your keyboard cable.

Toys By far the single most suggested toy of all was the Lego Mindstorms. The robotic legos are quite possibly the coolest toy in the history of toys. They aren't cheap, but they are oh so sweet. Else you could consider X-Files Action Figures suggested by E. Waugh. Home Entertainment and Audio Gear The Panasonic Portable DVD Theater was sent in by Joel Telling. Its a tiny portable DVD player obviously designed to make me froth at the mouth like a rabid dog. Several folks wrote in to suggest something I would like, but I wouldn't want to froth on. The Empeg Car CD Player. We've mentioned this before, and although they won't be ready for christmas, they are pretty amazing. 2.1 gigs of MP3s in a car stereo. They need a 9 gig version mounted in a home stereo component too.

Jon Jones (is that a real name? *grin*) wrote in to send a link to ADB I/O which you can use to automate your home for the ultimate in comfort and/or laziness. For the true audio junkie, how about the THX Speakers sent in by Chad R. Henry. Sure, they cost more than my car, but I bet they sound amazing. If you're on a more modest budget Cambridge SoundWorks has some slightly more reasonably priced speakers that I'm told sound awesome. Andrew Hobgood suggests checking out Panasonic SJ-MJ70 MiniDisc Player (portable). Pretty sweet if you aren't willing to chance it on the Diamond Rio (which was also one of the most common suggestions). Frankly any geek should be excited to get either. Rob Sheehy pointed out that Philips has 42 inch widescreen flat TVs that you could hang on your wall if you happen to be rich and wanna watch letterbox movies. This one has a VGA input too.

Random Terry A. Braun suggests that geeks need to get into making our own beer. Sounds like a great idea to me, although I tend to screw up toast. But if you're man enough to try it, you can get Your Own Grain Mill. Alan Mathews wrote in to suggest a A dilbert M&M dispensor McPhee's has some strange stuff, including a Punching Nun suggested by Glen Lipka Tom Berger suggested A VI Command Set Mug STriker RedWolf sent us a link to a chocolate bar shaped like a Pentuim II Chip.

Jason Grundy suggests the $6 card game Kill Dr. Lucky and a Card both from the aptly titled Cheapass.com. Rob Pelkey sent in a pair of gift ideas that are a world apart. The first is An Authentic Moon Rock and the second is a Jesse Ventura T-Shirt or Bumper Sticker. One is probably worth a little more than the other. The concept kitchen has this wierd Finger Stylus Thingee that you can use instead of a pen for some pen machines. Kinda wacky. Sent to us by Wyatt Earp.

Justin Higgins suggests that geeks should all own a copy of the Star Wars Radio Drama. Sure, it costs almost a hundred bucks, but at 15 CDs, it balances out to almost be a bargain. They ought to package it on 1 CD full of MP3s, throw a copy of the script on the disc and sell it for $20. I'd never heard of the Leatherman Wave before, but several folks emailed me to say they are cool. And then I noticed that they were actually advertising here. Shows how much attention I pay to who advertises on my own site I guess. But still several people raved about them, claiming that they're ideal for mucking around inside computer cases with. And Traci Earl sent a link to a site that makes nice Leather Cases for them.

Do you think stuffed animals are stupid? Well how about a Stuffed Plush Space Shuttle? Dave Brunberg sent us that gem. Stirling Westrup sent in a link to something called the Hoberman Sphere which basically is a crazily designed sphere thingee that expands from 9.5" to 30". Crazy looking. If you're looking for something caffienated that you can put in your mouth, several folks reminded us about caffienated penguin mints.

Wrap Up Well this was fun guys. Spending hours looking at crazy things that I can't afford has convinced me to take up cracking banks as an evening hobby. But what is quite obvious is that 1998 is a good year to be a geek. And maybe in 1999 Hemos can have his nanites. Nah.

And lastly, with all the commercial hub bub that tends to go on during this season, don't forget the true meaning of Christmas: Ham.

Jeff Foust writes " This press release from JPL states that the ion engine of NASA's Deep Space 1 is back online and has been running continuously since Tuesday evening.". In other science news, EETimes is covering what IBM has been up to in its R&D labs... focussing on projects that deliver products quickly. One of the developments is a 200 dpi colour 16-inch diagonal paperlike screen. I'd like one of those please ;-)

Frank W. Miller writes "Having worked on Station some years ago, I'm very excited to see it finally go up! For those that are into it like I am, here are some animations on the first few hours of the launch"

Rob Riggs writes "NASA has detected a new type of neutron star, called a magnetar. Their press release states that, on August 27, one sent out a burst of gamma rays so strong that affected our own atmosphere -- from 20,000 light years away! The star, SGR1900+14, has a magnetic field about 800 trillion times stronger than Earth's. "

Kevin Postlewaite writes "Everybody's favorite Beowulf Class computer Avalon has been upgraded to 140 processors (from 70). It now runs the parallel Linpack benchmark at 47.7 Gflops (up from 19.7). "

Rick Niles writes "I just talked to Jim Sweeney, a customer rep. from CorelComputer. He told me they would have WordPerfect 8 and Netscape 4.06 for the NetWinder by next month. Also, Quatro Pro by the end of the year and CorelDraw and CorelPaint sometime in 1999. I told him I'd be happy with X-windows support for Emacs and a release of the kernel source code for Netwinder. He assured me those things were coming soon. I also reminded him of the utmp problem and other problems and he said a new version of the kernel/compiler/libc is due any day now. "

Tarun Reddy writes "Very cool site where you can see a Java applet that shows you where quite a few satellites are currently orbiting. It will also give you detailed information on them as well. Got to just see it..."

Ready for the perfect egomaniac name to get your name out? Check out Stardust. Over a million names will be put onto a microchip and launched into space. Hurry up, the deadline is just a few days away. Thanks to Merijn Broeren for sending this in.

Jerkweed wrote in to tell us that things seem to be cool once again on the Beowulf thing. The Official site is back, and they've got the extreme linux cd available as well. Very Cool. Glad to see things are back where they should be.

Albert Strasheim writes "NASA, your favourite Beowulf-crushing-organisation and mine, is going to put up 3 webcams to allow the public to watch the X-33 being built." The cameras will be taking pictures every 15 minutes, and they'll be put online each day. Not as fun as the pathfinder stuff, but still kinda nifty. Read more over at nasa.

Raistlinn wrote in to tell us that Dcg has joined the growing number of companies selling Beowulf based distributed computers. Just another place where Linux is gaining acceptance. But that's not the important part, Jerkweed wrote in to comment that Beowulf, as well as Becker's eth drivers have been pulled from Nasa servers. The (extremely unconfirmable) rumour is that cheap super computers might be "Munitions" so buy those Extreme Linux CDs asap (or at least upload code outside of the US before it is illegal *grin*) Update The Beowulf site is still alive. I'm assuming the munitions thing is just rumor unless someone can prove otherwise.

Yesterday Red Hat Software announced the $29.95 parallel supercomputer. This CD-ROM is the result of the a collaboration between NASA, Red Hat and a number of research centers. Extreme Linux (some of you will know it as "The Beowulf Project") is all the software you need (with source code, of course) to cluster several computers and create your own giant parallel processing unit. For more information on this, zap to the press release.

Voyager 1 is now the most distant man-made object in space. Time for the aliens to pick up that plaque telling them where we live. I think that's the right plaque... Nasa has tons of them.
