Boris was key to finding the problem, but the solution was mostly a trajectory one. The article has a rather mangled explanation of the trajectory changes, and it treats the people who worked on it rather anonymously.... just calling them 'navigators'. The fact is that the trajectory changes done to save the probe mission were far from trivial.
Boris deserves a lot of the credit for saving Huygens, but several other people deserve credit but have been rather anonymous outside of ESA/JPL. 'Saving' Huygens was a team effort, and a lot of people played a part. There are a handful of other key people that the article doesn't mention at all.
Also there are a few factual errors in the article.... NASA couldn't simply sign a NDA to get the specs for the receiver, and there was a lot of effort by NASA to get the specs. Even after the problem was detected, Alenia resisted sharing information for many months.
so maybe it is the fault of the misleading, biased copy in the Slashdot writeup.
Ouch... I think $500 is a great deal for an early version of Tiger, don't know why you think what I wrote says otherwise.
OS X server sells for $500 retail, since select membership gives you a copy of server, it ought to cost at least $500. Granted, this copy is for "testing and development only." But, it's still a good deal -- especially if you really are a developer.
It's a surface feature of the moon with lower albedo, not "this half is black."
It's as dark as lampblack. It's so dark that the 'black' side is as dark 'white' side at night....and it's almost impossible to find the Iapetus terminator as a result.
Also, Phoebe has much more variation in color than previously thought, so it's still too early to conclude the Phoebe is not the source of the dark side on Iapetus... Computer models show that it is possible.

Phoebe Pictures Released
·
· Score: 3, Interesting
Yeah, but debris from impacts with Phoebe may be the source of some of the newly discovered small moons of Saturn: Skadi, Paaliaaq, Albiorix, Suttug, etc..
btw, a mythology search show Suttug has the best story, he's a Dwarf that stole the mead of inspiration from the Gods.
By 'Ground Time' they mean Earth Receive Time, or when the even happens at Saturn adjusted by a one-way light time from Saturn, or about an hour and a half.... Saturn is durn far away.
ET, TT, TAI, DT, etc... all just have a fixed offest from each other so it doesn't matter which one you use. ET is that standard (despite what my reference said).
Navigators (for spacecraft) don't use UTC, precisely because they want to keep in sync with the actual motion of the planets.
Missions like Cassini ar planned several years in advance (Cassini is planned until 2008). Unfortunately, Cassini is planned in UTC (to sync with the wall clock). If a leap second randomly appears, all of those plans will be off by a second. Sudden;y a mountain of printed literature will be off by one or more seconds.
It is just plain silly to use an unpredictable time system.
Ouch a troll mod for this, but no answer to why one would need ECC in a workstation?
btw, a 'troll' mod isn't supposed to be for someone you don't like or don't agree with... sheesh... google for it and figure out what the word means...
Pictures start coming down to the ground tomorrow morning and are dowloaded all day. Right now Cassini is busy taking pictures so it can't point it's antenna at Earth. And the pictures will take all day to download because even though they are using an antenna as tall as a 25 story building, so still can't get a very high data rate transmitting at 80 W from 10AU.
After that they will take some time to process, but when they are released they will either be at www.ciclops.org or saturn.jpl.nasa.gov.
Actually UTC is damn awful time system because of leap seconds which cannot be predicted. All calculations must use ET (Ephemeris Time) which is almost always SCET. The 'REAL' flyby occured around 19:35 ET, the exact time to be determined from tracking after the flyby.
For my applications un-optimised code on a 2 Ghz G5 runs about the same as on a 3 Ghz Pentium and a 2.4 Ghz Xenon, if I optimise the G5 code with xlf and shark I get my 2 Ghz G5 to run twices as fast as the Pentium or Xenon... but I don't have the intel compiler for the P4 or Xenon so that's not a fari comparison.
Anyway I expect this new G5 to greatly outperform a P4.
/opt is old school unix for 'optional'./usr/local is for stuff that isn't part of the standard vendor's install. On OS X perl is in/usr/bin/ because it is provided by Apple. Apple shouldn't put things in/usr/local/, only the local SA should put stuff in/usr/local/.
So why do installers like DarwinPorts put stuff in/opt/? So that you can wipe out/opt without breaking everything on your system. If you wipe out/usr you would be in pain, but you should be able to wipe out/opt without pain.
Dells cost a lot to maintain.. lots of bum hardware... parts take so lon g to replace under waranty that if you need to have your system back up in under three months, you just go ahead and buy the parts yourself.
I just did an app for OS X - we did it in Java/Cocoa. Works fairly well, looks like a good Mac application. And 90% of the code is directly portable to just about any other platform.
Couldn't you do the same with Objc and C++? The C or C++ part of your code would be protable and the Cocoa parts wouldn't be... heck ObjC is part of gcc, so the Frameworks stuff is really the only part of a 'pure' Cocoa app that isn't portable...
And a Java/Cocoa app is just as tied to the frameworks as an Objc/Cocoa app.
I have never figured out the benefit of using Java/Cocoa unless you really like to use Java for everything.
On a Mac, you can drag and drop songs out of the iTunes window into the finder and it names them as SongTitle.mp3. It probably doens't work that smoothly on Windows though...
Thanks for turning the years of pain into a good belly laugh!! I got over the disappoinment that my machine had a windows modem and I had to buy a new modem, I got past the fear of guessing the frequencies on my monitor when I set up X.... but I couldn't get past the frustration of trying to get the @#$@#$@!! sound card built into my motherboard to work.
Linux is great for starving students, save a ton of money and learn a lot about computers... but now I have a real job and I can afford a Mac. And my Linux experiences make me appreciate it sooo much more:)
Apple Computer wants to be sued!!

Here's my conspiracy theory...
Apple Computer wants to be sued by Apple corp to that they can get out of the restriction against being in the music biz. Maybe they want to buy a label, maybe they want to start their own, maybe they want to burn music CDs on demand in the Apple store.....
In LA, on the westside, where tons of music industry people and entertainment lawyers hang out there's a huge billboard with just a guitar, the words "Apple Music", and the Apple computer logo.... this billboard is a very minimalist way to say: "C'mon sue me, I dare you, pthbbtt!!!"
This billboard and ads like it must have been designed to provoke this lawsuit. I mean c'mon, Apple's lawyers can't be so dumb as to let this one slip by.
In LA on Wilshire by UCLA is a huge billboard with just a guitar and the words "Apple Music" and a little Apple computer logo. A very minimalist ad that simply says "Sue My Ass, I dare you!"
Apple must of known that they were going to be sued, since it looks like they were actually provoking this lawsuit. This billboard is in LA where tons of record industry people are bound to see it.
The conspiracy theorist in me thinks that they are looking to provoke the lawsuit so that they can somehow get out of the restriction against them being in the music biz....
I just wonder what they're up to.... they could do really cool things for small time musicians if they had their own label that fed straight into ITMS...

Actually, it might be possible to figure out how to control the fans from the Darwin source, so a Linux port might not be as hard as I thought... but it still will require more than just a recompile:)
Sorry, but all of those fans require software to run them... software built into OS X. Porting Linux to a G5 is not going to be easy.... unless you want to build your own cooling system.
This is the company that copied the Mac interface right down to details like throwing away variable-sized elevators in order to look more Mac-like (and got sued for that one too).
What are "variable-sized elevators"? What is the story of this being thrown out of windows? Please elaborate

I can imagine Lockheed can work something out for the few users that need Powerpoint (managers that make presentations).
Engineer's run a lot of powerpoint, not just managers. Around my work, people use powerpoint more than word or excel.
What puzzles me is why they didn't just get everyone Macs and replace the Sun and the Windows machine with one shiny new G5.
