Let's see, you could use GPS as another poster mentioned. As soon as GPS is accurate to within a millimeter, that would work
You could use laser range finders. Assuming the soldiers can see each other, or don't mind looking like the Hatteras Lighthouse
You could sync the clocks on the individual relay devices and measure transmission delay time. That could be done with small radios
You could have a system where one mic can ping another mic to figure out its relative distance. They'd need to be doing that every 200 milliseconds and still won't be real accurate
You could put two webcams on the soldiers and use stereopsis to figure out the distance to other soldiers. It's not the soldier's position, you need the exact microphone position within a few millimeters
You could use a single webcam and just guess distance to other soldiers based on assumed size of soldier. See last comment. Aside from a few more pounds of computer gear to carry around, the addition of radio/ultrasonic/laser emissions and the exposures involved, the results would be as accurate as soldiers just listening to where the shot came from. This contraption is made to point an IR laser at the sound source immediately, something the soldiers would be hard pressed to do while gunfire is happening. Basically, there are lots of ways to skin this and it will take more than 10 minutes to really work through it.
Irgun: They were a small group frustrated with Arabs attacking the Jewish settlers, so they fought back. That's the only thing the Arab attackers understood and it worked. The Irgun were reactionary and didn't exist until 1930 or so. They even fought the British for a while. Yeah, they were a catalyst for conflict but that was happening to them already. They weren't anything like Hezbolah today but they have the same roots.
The first sound is the direct sound. Seeing as the calculation for direction is done in a about six milliseconds, any reflections would arrive much later and can be discarded. The robot will twiddle its thumbs for 200 milliseconds and figure the echos are just that - echos.
The four microphones would be in a known fixed position. Knowing that sound travels at 344 meters/sec, not all the microphones will pick up the sound at the same instant. There will be millisecond differences between the microsphones as the sound passes over the array. You can then use software to phase correlate the sound impulses and get a very accurate triangulation of the direction it came from. Putting microphones on individual troops who move around will destroy the ability to measure the delays - you don't know exactly how far apart the microphones are and therefore don't know what the standard delay time is.

Israel? It's remarkable how any topic here turns political within a few posts.
But now that everyone has warmed up the bed, I'll jump in. Israel started getting colonized by Jews in the early 1800's and in larger numbers in the 1880's. The Jews didn't invade Palestine. They were actually buying land from the Palestinians - who have had about 2,600 years to form a nation since the last time Israel was there but never did. That land was always administered by the Romans, the Arab neighbors, Turkey (Ottomans) or the British after WWI. Idunno why, it just was.
The Jewish settlers and Palestinians had frictions building but nothing huge. It was getting clear that the Jews and Palestinians needed to be separated so the U.N. partitioned the land into Jewish and Arab sectors in 1947. The Arab League preferred the Jews to be dead or elsewhere. The big one hit when Israel declared independence in 1948. All this time, nobody was getting "thrown out" of Israel until the day after its founding when all the Arab neighbor countries attacked. The Palestinians who were automatic citizens of Israel didn't drive the attack, the Arab neighbors did.
The attacking Arabs (Egypt, Iraq, Jordan, Syria and Lebanon) told all the Palestinians (who hadn't figured it out) to leave the Jewish sector and let the Arab armies wipe out all the Jews. When that was finished, the Palestinians could come back and claim ownership of the Jews' land and possessions. It didn't work out that way. The Arabs lost the war.
All the Palestinians who "got out of the way" [~700,000] were not allowed to return but all the Palestinians who stayed in Israel were welcome to live in peace and take part in all of Israel's institutions. That's why there are "refugee camps" full of hostile, displaced Palestinians. If anyone is upset about that, then why not be upset about the 850,000 Jews expelled from Arab countries in that time period, or the thousands of Jews slaughtered, captured or expelled from Gaza and other parts of Palestine?
Q: Why don't the Arab states who started that mess accept the displaced Palestinians as their problem? A: The Arabs don't want them in their countries but they'll supply weapons and ideology to let them help destroy Israel. The Jews didn't do anything to the Arabs except exist - and embarrass them in 1948.
To the Arabs, being beaten by Jews [clearly sub-humans] was like being beaten by a woman [also sub-humans, eh?]. The Arabs lost face and that's why they'll never give up until Israel is gone. That's what all this nonsense is about. After that, everyone who doesn't look, act and pray like a Muslim will be attacked until they're gone... or until everyone comes to their senses.
I really fear for this planet over the next few decades.
OSX 2001 was garbage, even Mac users admit as much.
Correct. In 2001, there wasn't much there. By 2002 [10.2], it was pretty good. Stuff just worked, so Vista was only bested by 5 years, or almost 2 years if you count the current features in OS X mimicked by Vista in their unique, crudely inferior way.
It only figures... Microsoft expecting a compendium of proprietary digital glop to be officially embraced by all. Why even submit this for standardization? De-facto "standards" have worked so well for them [ -and so badly for everyone else].

Upgrade through extortion is not uncommon at all in the high powered computer [graphics] world.
First, buy a $600,000 Quantel compositing workstation. You want glints, glows and shadows with that? $15,000 later, they send the 60 digit unlock code. No hardware change required. First time I saw that, I said *WTF* so loud they heard it back in England. If it's in there, why can't I use it NOW?
Same with some of the old 3D modeling software on SGIs etc. Not even an updated piece of software, just a bunch of keys to turn on the features - and expire them.
It seems that Tony and George were both upset about how Saddam was hung. I think they were talking about putting him back in charge. Really. He was the only one who could contain all this genocide going on now. He didn't put up with any of this shit. With Saddam gone and the Americans' policy of "why can't we all just get along", it's back to business as usual in Iraq - kill everyone who isn't in your militia. The Americans being there is just a side show now.
Absolutely... not being able to standardize on a platform is a huge problem for upgrades. We need to find the application which will do our work, then tune up the platform which supports the application, mostly by hand. Most of the workstations still run on PCs which leads us to the PC specific issues. The ones we could migrate to Macs, we did. Afterward, there were none of the previous irritations on those workstations. The other problem is the cost of the application software. It can easily cost more than 3 times the hardware price, so we pick and choose which workstations get certain capabilities. Nothing was the same.
When we did the transition, we installed the new Mac along side the existing PC running the same application (mostly After Effects and Maya) and told the operator to get comfortable with the Mac. There was resistance from the operators (remembering the bad old OS 9 days from school) but they started using the Mac to do more compositing while the PC was rendering. It only took about 3 weeks before the operators told us to take the PC away. They could work faster on the Mac. Something that took 40 minutes to render on the PC was done in 18 minutes on the Mac. We couldn't believe it either but there it was - and the PC was no slouch. Within six months, the operator had his own PowerBook sitting there.
Same with Sales and Production. The Sales people thought we would go out of business with these Mac laptops but a few weeks of showing them how to use a Mac relaxed all of that. The bonus is they quit coming in from sales calls with viruses and most of them own personal Macs now.
How did you measure the improvement in security, productivity, and maintenance and what percentage was each and exactly how does "spectacular" rate to a real world number?
Now that you've called attention to the fact you asked a question [and I didn't answer because I never looked at this thread again and there was no email], I re-read beyond this point with a -1 threshold. Reading the posts which came after yours, particularly about centralized administration of Macs, pretty much bears out what we've also discovered. It's pretty good on the Mac side but don't take my word for it. I'd suggest reading the other posts which follow.
We did play with Netboot from one of the Xserves but our machines are too different to make that useful. It's hardly worth it for only five desktop machines we can call "identical". Each workstation is task specific and has a number of operators. We also have roaming profiles but it's a challenge for us as each user may or may not continue a job started by someone else on the same machine. Half of our systems aren't operator specific so we stick with univeral logins on the systems and user specific access on the file server.
I also re-read your post assuming you weren't trying to be a jerk and came away with a different take on what you're saying. I probably judged your statements too harshly because I had the Windoze fanboi filter turned on. It's a common thing on Slashdot for someone to say "hey, Macs actually work" and get trounced by a dozen Windows admins who don't believe it, even without any experience on the subject. The Windoze fanboi filter still comes on as I read and need to sudo kill -9 the instinct. I'll apologize to you for that here if that notion is accurate. I've learned to expect no less from Slashdot.
Of course, in certain environments, what you're doing and saying makes sense. Not in ours. Hell, we just got rid of 7 workstations stuck on NT4 and updated them to XP in August. They'll stay on XP but we can't put SP2 on them yet because the primary app will break. That's the kind of nonsense we have to deal with on isolated, select Windows workstations.
On the other hand, all of our Mac workstations run really well if you shove enough RAM in them and attach fast cache drives. The biggest problems we face on the Macs can usually be solved over the phone - which means it isn't broken.
