Agreed, mostly. I _do_ work with multi-million-dollar orbiting devices, and my career expectancy (in this area, at least) would be shortened by something like that post....:/
Heh. Actually, the satellite control industry (Integral Systems, Harris) does exist separate from the satellite construction industry (Boeing, Loral, Ball, Spectrum, and that's just some in the US), and you can now hire PanAmSat or Honeywell (the old Allied Signal group) to control your satellite for you once you've launched it.
How many people have satellite transmitters? Well, how many people have DirecTV? EchoStar? Even better, DirectDuo or DirectPC? Those receive and transmit to the satellites - not, of course, using the command-and-control paths. Transmitting to a sat is simple.
How many openly documented satellites are there? Hundreds - most of NASA's satellite documentation can be retrieved through FOIA requests, if not through academic queries or Web searches. You can learn an awful lot about commercial sats just from the vendors' web sites (like whether they have in-band control, and the frequencies used for C&C for different birds).
All that aside, it's been an interesting thread - well worth the posting, even if a bit uninformed in premise.
Would you rather be oblivious? As it stands, *BSD fans see this note, and a lot of work is going into developing a fix, not only for BSD, but for Linux as well - if you want to follow the status, follow the links/mirrors/forums. The tool these guys are using (publicly available) has discovered major flaws in the internal VM implementation - what are the odds you'd EVER hear of that with M$? (BTW, has anyone run this against M$'s NFS implementations?)
Besides, part of the fun of open-source is watching the evolution. The emails documenting how this evolved are fun to read - wonder what M$'s equivalents say? We'll never know....
One of the places for government here is the investigation and prosecution of crimes. Is it a crime to break into a bank's network, copy financial data, and blackmail them? Yes. What can government do about it? Track the perpetrators down and put them in Leavenworth.
IMHO, the government needs to clean up, unify, and rationalize the laws on computer security and intrusion, clarify the jurisdiction issue (exactly who investigates what, and who prosecutes it), and get aggressive. MAKE corporations disclose intrusions, and cooperate with investigations.
We do have critical systems that can be influenced through the Internet. They need to be protected. Let's do it with one set of rules, one set of enforcers, and one set of penalties that's uniform across the US.
I just started grad school and I buy myself a game whenever I take a test.
Man, if I did that, I'd have 3 more games since September, and a MUCH lower GPA! You must be a full-time grad -I KNEW there was a reason I wanted to do grad school before getting a job/wife/kids - carrying a full load with those 3 is putting a serious crimp in my Everquest time - I'd never be able to fit in a new game.
Well, maybe Star Wars Galaxies, when it hits... hope that's after finals next term:-)
A fully functional hospital - which means it has fully functional narcotics, fully functional labs where various things are grown, fully functional medical records... there are lots of things that a quick check of a person's bags will prevent from escaping. Like a big sealed envelope full of confidential medical records, or a few dozen vials of morphine, or a couple of pounds of powdered unicorn horn... c'mon, the fact of the search is itself a powerful disincentive. A security guard may not be able to identify an anthrax sample, but he/she/it has been briefed on who to call to check.
Read the article - he works at the National Institutes of Health - a government agency.
As for the search on the way to his car... look at where he works, and ask yourself, what kind of things could they possibly have at NIH that the government doesn't want escaping?
That's one of my pet peeves (down, boy) with X, too. Wouldn't it be nice to have a clean, all-up, level-set version of the display engine? I understand the need for backward compatibility, but even X has had problems with that - I remember going from R3 to R4 and having to rewrite apps to avoid the new core dumps. A new, clean, high-level version of X - X12, maybe - would be nice - let the folks who want to stay backward-compatible play with X11Rn, and let the new development move to X12.
That said, do I have time to help on it? No. So - unless people start being loud over at X.org, things will remain the same - X11R6.x.n.q.1 and so on.
The applications, sure, they write quite a few of those - not a whole heck of a lot of demand for some of the stuff they do. BUT, the name of the game for the last decade has been COTS (Consumer Off-The-Shelf) integration - find things on the market and glue 'em together to do the job the gov't wants done.
They DO like having someone at the other end of a support contract that they can yell at, so the free software world hasn't penetrated as much as it could have, but I can't remember the last time I saw a government-specific OS that wasn't running on government-specific hardware, and those get rarer every day.
The MIGs could do that because under the rules of engagement, our forces were forbidden from launching until they had a direct visual ID on the other aircraft. Silly, given that the F4 was designed to fight Soviet frontal aviation over Europe, in a massed air war where they'd want to get in 3 salvos before they could see one another. The Phantom's missiles were set up to allow the back-seater to track multiple aircraft while launching (Sparrow) missiles against one enemy, then engaging others with Sparrows or Sidewinders.
Yes, this IS responsible for the revival of guns in American fighter jets. It's also responsible for our current ROEs that provide positive control and take advantage of the technological superiority we've built up. Most of the folks in our military spend lots of time working on integrating the new capabilities of their new toys into doctrines that don't leave a lot to chance - one reason it takes us so long to get a new weapon from the drawing board to the field is that we do so much integrating and testing.
The AIX 5L release is "Linux-capable" - it should be able to run most "vanilla" Linux apps with recompilation.
That said, IBM has been pushing several of their AIX selling points into Linux, like their Journalling File System logical volume manager. Their system management tools are pretty good (no SMIT cracks, please) and they have good network management tools. I got out of the crystal ball business a while ago, but I imagine IBM would like to be spending their money "productizing" Linux on their platforms rather than supporting their own OS.
I'd say they're trying to take a piece of Sun's pie, and maybe try to keep some folks from moving to Win2K. Looks like a good price/performance system if you need that much to start with.
Yeah, but I'd like to be able to watch something _other_ than cartoons:)
We ration our daughter's TV viewing, and about 80% of her current ration is educational TV cartoons - Arthur, Dragon Tales, etc. (she's only 5). If I ever showed her Cartoon Network, I'd have to buy another converter box to get to see what I want to see during the time when she _can_ watch.
Not that I don't enjoy the occasional episode of The Tick, or Bugs - it's just that I don't want her running around yelling "Spoon!" at kindergarden.
Basically, I want to see Archer kick a giant lizard in the love spuds, chuck one up a seven breasted alien bimbo, fight off a Gooboid battle fleet, and then vapourise a couple of small planets just for laughs - and all before breakfast. Any chance of that?
Not much - this ship's popguns can't even vaporize a small moon, let alone a planet.
I wouldn't want anything "grimier" than Farscape - some fo the effects on that show have been more than disgusting, even if entirely plausible. Andromeda has been very uneven, IMHO.
What I want... is a show I can watch with my kids, and have the innuendo and sexual content go right over their heads while they enjoy the spaceships/aliens/shoot-'em-ups/etc. The way I did with my parents, way back when. It doesn't have to have a 5-year epic arc like Babylon 5 - it just has to be fun TV that we can talk about for the next 20 years.
Given that Kirk and Spock and Scotty invented the original series' time travel system, any references to it should be (1) subtle or (2) alien. The DS9 temporal cops shouldn't be showing up much.
Bakula has a solid acting career already behind him, is used to the kind of mania ST fans can generate, and does a pretty good job of portraying "competence-in-spite-of-hickness," which I'm guessing is going to be a major theme of this show.
Humans, the new kids on the block - comin' to mess up YOUR neighborhood to! This should be fun.

I'm an HLA plankholder - have the certificate around here somewhere. Was on a team that modified the CCTT CGF to play in HLA way back when, around '96-'97 or so.
We had a couple of SIMNET units to compare against - "played" in them some evenings, too, to figure out how some of the interactions worked. We bumped up against the limits of the DIS protocol pretty fast - biggest cost was that the update processing from all those other entities eventually stole all the processing time your local CPU had to do its simulation in. Multicast helped, but managing the groups was a pain. HLA's publish-subscribe model worked better, but the RTIs (Run-time Interface, for those playing along at home - the "servers" in HLA) didn't perform too well - didn't scale for us. But that was then - I'm sure they're MUCH better now.

Ha HA!
I actually worked on that puppy! Rough and clunky it may be, but remember, it's a DoD procurement:> - we did the best we could with what we had at the time. Hundreds of thousands of lines of Ada - yes, Ada... and it's still one of the best things I've ever worked on.
We used to play in 'em - "test" sessions where we'd do all kinds of strange stuff to try to crash the simulators or the CGF (computer-generated forces, everything that moved that didn't have a person behind it). We joked that if the budget fell short, we could roll up the high-bay doors and charge folks $15 for 10 minutes. You'd need to come as a crew - it takes 4 to run an Abrams (ok, 2 can do it in the sim, but the person in the turret running the gun and sights is gonna get bruised on the equipment).
The earpiece uses skull resonance for the speech so you won't need the mike boom.
So you really want a comm implant - not a comm badge. 'cause the comm badge has a speaker and mic built in, and has to do some interesting noise filtering, I'll bet... especially during a long, drawn out battle when phasers are bursting against the shields and panels are exploding and bodies flying everywhere....
Ok, back to the subject. Consider a phone system in a hearing aid-style package. Battery, very-low-power transmitter, bone-induction mic and speaker... all in a package that fits inside your ear canal (not for use while playing contact sports!). Relay to the local "network" if you're in-town, or to a relay center in a car, pack, etc. if you're out-and-about.
Private schools can cherry-pick their students, and can discriminate on a number of bases; privately owned roads are impossible to find in rural areas, apart from privately owned lands (How do we get to the next town? Through them thar woods, boys!); and the FDA has saved hundreds of thousands of lives by making people test drugs, and ordering the withdrawal of bad ones from the market.
It ain't perfect, but it's a darn sight better than not having anything.

- Odds that the flunky-villain dies a particularly horrible death? (Say, explosive decompression?)
Hmmm... from my probability courses, the odds on that first one make the rest almost sure bets... once the first comes to pass.
