considering there are commercial systems getting 1 cm accuracy out of regular CA code GPS (non military) I just don't see the point... Whatever man, its not my tax dollars..
Hey Europe - knock yourselves out. Glonass was nearly a total clone of the GPS system - except that like almost all of the Soviet harware built from stolen US blueprints it never worked quite as well - You can bet that the EU system will also be a clone of the existing GPS system. Unless they are going to come up with some major accuracy improvements (unlikely due to cost) I don't see that it does anything other than keep Europes high tech industry working and sucking Europes taxpayers dry...
I agree with you 100%, diving has many risks. My point was that by taking the conservative nature of the tables out of the equation (which don't easily allow profiles which recoup residual nitrogen time during the dive) that a diver taking a chance has a greater probability of screwing up. As someone pointed out in another post (and you mentioned above) the divers health has a tremendous amount to do with how he will react to breathing gas under high preassure at depth. Until I read this article I didn't know that they made a dive computer specifically for Nitrox diving - I have always considered Nitrox to be something that Sport divers should stay away from - balancing the risk of the bends with oxygen toxicity seems insane just so you can spear a few more fish or take a few more photographs.
In my experience as a diver for the last 15 years, I have seen many divers who rely on dive computer technology to get closer to the edge and get more bottom time, longer dives, deeper dives, etc. The original "paper" dive tables were based on the experience and testing by U.S Navy diver's and are VERY conservative. The advent of widespread use of dive tables for recreational diving resulted in diving being a lot safer. The advent of computerized tables has promoted a false sense of security to the diver (kind of like having a radar detector in car - you might avoid more tickets, but you may speed more also) - I myself have dove profiles I would never have attempted based on the dive tables but the computer "said" it was OK so we did it. Here is a story about a dive computer specifically designed to be used with mixed gas diving (nitrox) adding yet another element of risk over regular diving. I think that dive computers should come with a waiver that says "if you trust you life to this device you do so at your own risk". Based on what the story said I would never have gone flying so soon after diving using regular dive tables - they threw the dice and lost, and now they want to pretend that what they were doing was risk free and the dive computer caused all the problems - Its nice that the dive computer maker is recalling the units to make them more conservative. Too bad those divers didn't buy the "common sense" computer too.
At the risk of posting yet another redundant post about this - I would like to say that it makes my stomach turn loops that there are people getting paid to write useless religious/metaphysical analysis of movies like the Matrix. Give me a break, its just a movie. And how does this rate as "stuff that matters" ? I guess I should just logoff Slashdot and go do something constructive instead of getting upset about it - sorry for the rant and waste of bandwidth.... .
That was certainly one of the points that the backers of the law were trying to make, I would argue that it is also a persons choice of where to work (flame suit on), but it wasn't the waiters and waitresses of Florida that passed the law, It was all the people who couldn't get past their prejudice against smoking (once again I do NOT smoke). Remember these are the same voters who made the last presidential election so much fun:-)
I hate spam as well, and don't want unecessary laws - I don't smoke and yet I voted against the law in Florida which banned smoking in restaurants - because a person can choose not to go to a restaurant with smoking. BUT its a lot different with spammers - no one gave me a choice of whether I wanted the stuff in the first place. The proposed law requires people to opt-in or choose to get the spam - its not regulating Internet content, its protecting MY rights to privacy. Its a pretty good start at fixing the problem. .
if you look at the schematic you will see that the designer has implemented the classic "instrumentation amplifer" (two non-inverting stages for high impedance, one inverter followed by a differential stage). The advantage of purchasing a single package "instrumentation amplifer" is that it saves tweaking. BTW if you build the authors circuit be sure and spend the extra pennies for 1% resitors it will work a whole lot better.
I agree - no great inovation here. As I sit here hacking my neighbors Linksys box because his channel was too close to mine (he didn't change the password, he didn't turn on WEP....) what a dumbass..
The problem with this scheme is that if every house had 802.11G the 2.4 GHz spectrum would be a mess of broadband noise...
There are several companies that build interfaces to go from the OBD2 protocol to an async serial stream you can connect to a laptop or PDA www.OBD-2.com .
No big surprise - Management had to wake up eventually.
In addition many computer systems and networks have reached a level of complexity that can no longer be serviced / designed / maintained by an MCSE or some kid who took a few HTML classes at the local community college. Its true that anyone can "throw" a network together - and as my boss often says, "when you want it bad, you get it bad..." At my place of employment, engineers are actively involved in serious systems design and modeling of our networks (before they are deployed) - they are not shopping out of a Black Box catalog and hoping it all plays together.
The parent post makes a good point, and I would add the following - time for less quantity and more quality...
Lightbulb goes on - Your probably right, FX32 waa never that impressive, even on an Alpha. It could run solitair but not much more without bogging down severely.
Most of these things are designed with LPI (low probability of intercept) in mind - they are nearly impossible to detect with even the best equipment - now consider the technology that our opponents have and it comes out to be 0 risk. The benefit of knowing where your forces are, to prevent fratricide, far outweigh the astronomical odds of having your transponder tracked.
I am pretty sure you need to see the clue fairy - it is the typical democratic cycle - the democrats screw up the economy, and just before the shit hits the fan - they get voted out - the republicans come in and get to preside over the ensuing economic disaster - they fix the problems and when everyone is in the "feel good" mode they vote the democrats back in and they get to preside of the economic good fortune while increasing social program spending and waste -repeat.
No programmers do that where I work - Systems Engineers design systems to customer requirements and flow those requiremnts down to others (programmers as well as others - logistics, documentation etc). A four lane bridge and a database are not anywhere near the same thing - a database could be (and should be) coded by a programmer - a four lane bridge encompasses a multitude of systems, and disciplines (mechanical, structures, civil etc.) and is designed by engineers.
are you an engineer that writes software or a computer science major who does electrical engineering - I have met computer science majors who by all rights I would call Systems Engineers - they had a complete understanding of the hardware at a very low level and how the software makes up these systems of systems - on the other hand I have met computer science majors who were just code monkey's or sys admins who thought what they did was engineering when they plugged a PCI card into a motherboard. The very best software programmers that I have personally met were all Electrical Engineers (and one PhD in Physics who wrote radar signal processing code). I think the trend in Universities offering "software and computer engineering" degrees is telling in this respect - its a grey area.
How many bonehead people doing criminal activities via cell phone will purchase these, and then be mystified at how the cops know exactly where they are. I am thinking automatic jail time for being a moron.

There were at last a couple of GPS receivers used for precision timing systems that could receive GPS and GLONASS.

Or maybe its Stephen Hawking trying to make a few extra dollars.

when that software crunch time comes - nothing helps more than a six pack of Mountain Dew and a box of Krispy Kreme donuts.
And also a dos boot floppy with format, sys, fdisk, and a text editor.

Yeah, I have to work late tonight.
No I won't be home for dinner...
whats that? What am I doing at your sisters house?
ummmm - must be Russian GPS jamming equipment - damn phone - I guess I'll have to take it in for service.
I love you too...

funny - I don't remember Michael Knight urinating on KIT, but I could have missed that episode...
I love this movie !
1. The Fifth Element
2. Dark City
3. Life Force
And I agree with a poster who mentioned Army of Darkness - Great flick !!!
