Have you ever seen a biodiesel vehicle in operation? White smoke pumping out. I have followed my friend who has a biodiesel burning Dodge/Cummins truck from Nashville, Tn to Dayton, Oh. (among other trips that are 100s of miles) I didn't see any "white smoke".
Have you ever smelled a biodiesel vehicle in operation or at rest? Uhg! What a stench. The slight smell of french fries maybe, but I like french fries. No worse than any other diesel.
Have you ever driven a biodiesel vehicle? They are a bit quieter than when running on regular diesel but they also lack power compared to when running on regular diesel. He pulls a huge trailer packed with heavy gear all over the southeast when going to hamfests. It has plenty of power.
Unix copy/paste? What's wrong with it? I copy stuff to and fro quite happily. Or are you whining about the "select is copy, middle click is paste"? Because while you were apparently sleeping, the mainstream stuff all started supporting Ctrl+C/Ctrl+V.
Let me see, gnome-terminal: No emacs: No Ctrl+C never work in terminal applications, and I don't think emacs have ever cared about any kind of UI standards.
I've always left ads on Slashdot because I 'support' the culture, but this is the final straw.
Culture? Hahaha, you make me laugh. Hahahaha! It's almost as funny as the tards that were bitching that/. was not balanced with their coverage of Windows about 5 years ago. Or how about the ones before that, they felt betrayed because Taco "sold out" to Andover. Hahahaha!
My friend Bill Brown (WB8ELK) has flown more than 200 balloons and has had great success of long term flights with balloons that simply have a pinholes poked in them. One he launched in Alabama a few years ago flew all night and was last heard off the coast of Nova Scotia.
After doing research based on your post, I see that the current required to cause detonation in this case is 1/2 an amp. The only way that much current could be induced on that cable is if the antenna came into direct contact with the wire.
Seems to me they should install an inductor at the blasting cap to decouple RF from passing though it if such low current can cause detonation.
I would not want to work around this stuff. From my calculations, these caps can be detonated with as little as 1 volt present across the blasting cap.
However, I stand by my accertion that a cellphone could not cause detonation.
One would think if such explosives were so volatile, as to be set off by passive RFID tags, the military would use EM pulses to detonate enemy explosives.
I agree with you, I would love to see this actually tested.
At a distance of 8 feet with a 5 watt UHF handheld radio the RF power density would be.0285 mw/cm2.
Dosen't take much power at all to set off those blasting caps. Seems as if lightning would be much more a potential hazard if they can be set off with microwatts of power.
You know the difference between an intrinsically safe Motorola radio and one that is not? The insurance policy. Don't quit *YOUR* day job.
If you notice, the largest hazards are multikillowatt MF transmitters (AM broadcast band) and HF transmitters. This is due to the frequency, power involved and the length of wire on the detonators.
Good luck getting a 100 watt VHF or UHF 2-way radio to set off a blasting cap at ANY distance.
The Inverse square law, it's not just a good idea, it's the law!
Hey guys, love the show. I was wondering why you have not tackled the "Blasting Zone" myth. You know, were you are asked to turn off 2-way radio equipment and Cell Phones when passing through a "Blasting Zone". I ask this because several years ago there was an accidental blast in my home town and many speculated on the radio that it was caused by RF from a cellphone. Several of us amateur radio operators kind of laughed at that because there are few guys that supposedly tried to set off a blasting cap with radios, just to see if it could be done. They went so far as to even wire the blasting cap into a 100 watt VHF (low band ~50Mhz) radio's antenna jack. Nope it didn't go off. Using inverse square law, it seems very unlikely that a cellphone or 2-way radio could set off a blasting cap at any distance.
What, does "CTRL ALT -" not work in Windows or something? Since you have re-framed the argument in a new light that only allows you to run a Microsoft Operating system (because of Office).
That seems to work just fine for my friend who has been blind since birth and uses OO on Free BSD.
Or, you can look at it from the perspective of a large organization (Mass. gov't would qualify) "We want our features working and we want it working out of the box. We don't want to have to go through the problems of hiring a few developers, and a SLEW of testers." In all honesty, that is what they will say - right or wrong, and personally I don't think it is that wrong.
Where is this magical software that "just works out of the box"?
Since they're operating in the license-free 900mHz ISM band
Not a good band to be operating in for weak signal type stuff. The 300Watt paging transmitters operating in that band could cause them some trouble without the use of a helical front end on their receiver.
What's wrong with that? (So long as header,menu and footer do not expose anything if called by themselves.)

Well, the quote might be taken out of context but I have never heard it was referring to the use of packet switching for PTSN. I can find no evidence that AT&T was experimenting with packet switching in 1950. That's only 3 years after the transistor was invented and 8 years before the integrated circuit was invented. If you have such evidence, please add it to the Wikipedia page on Packet Switching

Bell Labs did everything first: telephones, lasers, telecommunications satellites, electronic and packet switching, UNIX, etc.
Um no, BBN did packet switching first by building the Interface Message Processor. AT&T said it could not be done.

No pop ups for me. Something is boned on your install.
That is what I used to use on the Mozilla config, back in the day.
What site are you going to that has pop-ups?
I use Drudge as a test, and FF 1.5 is working just fine.
No Pop-Ups.

I have done a weather balloon project myself. Sounds like what you wish to do is a zero pressure balloon. You will need to read FAR-101 for regulations regarding free unmanned balloons.

Hey I'm not saying it can't be done. I'm saying it can't be done with those specific frequencies and power levels.
The safety recommendations you posted are correct, because they are conservative to the point of absurdity.
