Hi - I'm not sure I know what your question is. I am agreeing with one of the superposts that it is hard to ignite many liquids, the range of air/fuel ratio that supports combustion is usually pretty narrow; I'm just saying it is not harder than I think, because I know it is hard. H2:Air is explosive over a range of about 20%-80% H2, this is huge. Gasoline by contrast has a very narrow range.
Further, a graph of detonation pressures shows that
the effects of a hydrogen detonation will be essentially the same
for much of the explosive range (20 to 80 volume %).[15]
That'll be why in most cases there is no such thing as a "pump lock". Arizona when I lived there, California (AFAICR) and Massachusetts where I live now have pump locks, which are intended to allow fuel to flow unattended and to stop when there is back pressure from a full tank.
In my experience they are more common than not.
...its harder than you'd think to ignite the vapors...
No, probably not harder than I think, I spent a fair amount of time at Caltech trying to ignite various vapors. H2 is pretty easy, in fact it has a wide range of straight up detonate on ignition behavior. But most contained liquids won't...
Both assume that you're pretty sloppy with the nozzle.
The last time I set a pump lock and walked away from the nozzle to clean my window, there was some odd jolt in the line and the nozzle jumped out of the side of the car and spewed about a quart of gasoline under my car before I could stop the pump. I pushed the car away from the puddle hoping the catalytic converter was not going to ignite the vapors.
I didn't think I was being sloppy at the time.
I see a lot of humorous answers to your question. But one response included VNC. That is the best advice in the lot. I had the same story. My mom used Windows at work and so she had Windows at home, and I had to spend all sorts of time fixing things. We bought a Mac, and it drove her nuts for about two months. But I installed VNC and she would call me and I'd log in and walk her through what she wanted to do. She became quite good. The she discovered iMovie and that she could make DVDs...with music...with Ken Burns effect...done. She'll never going back to Windows at home. Still has to use Windows at work because that's what all lawyers use apparently; no doubt to pad the hours billed.
At some point I could no longer give her expert advice on iMovie because she was much more experienced, and she discovered the Genius Bar where they could give good answers actually.
So now I get advice from my mother on how to use iMovie, which makes her very very happy.
Just to be clear - I have to verify my key via a channel other than the Internet. Say via mail, or maybe a secret Youtube video or some such. Not to say I can't do that, but it is a lot of extra effort.
I have it - I will publish my KEY on my roof so that anyone can see it with Google Maps.
As an alumnus I like to point out why the Cal Tech usage is in addition to being wrong, also confusing. Cal, when used to refer to institutions of higher learning in California, always(?) refers to either the University of California e.g. Cal Berkeley, Cal(R) Bears, http://calbears.cstv.com/ or to one of the California State University campuses http://www.calstate.edu/ with particular attention to Cal Poly. I sure wish I had a Cal Poly sweatshirt given the number of times people have confused Caltech and Cal Poly.
In any case, Caltech is in neither the Cal State University System, nor the University of California System.
I saw the picture and it looked nothing like any real bomb that I have seen (pictures of only!). Aside from "24", where have you seen bombs that looked like that? What that looked like to me was a breadboard with LEDs and a battery. Like I've seen in a dozen EE lab classes, and I think you can still buy that stuff at Radio Shack. I suppose the common element is a battery, which even my razor and disposable toothbrush come equipped.
In all sincerity I would ask, are you an expert, and can expound on why you think that looks like a real bomb?
By having the scopes at the opposite ends of the Earth and sharing phase accurate data between them they have an aperture size equivalent to their separation. Which is larger than any single scope you could launch. You could launch two scopes and do the same thing, but the dish size you get on the ground is rather larger than what we can launch.
I'd be interested in a reference to the story. I don't recall hearing it as a student, though the link between Parsons and Crowely was used to explain some of the very interesting sculpture on campus. And sorry to be pedantic, it is Caltech, not Cal Tech. The difference being that Cal is usually used to refer to the California State Universities as well as the University of California system. Caltech is a private institute.
All apples do AFIK. And it is a DVD, not a stack of 6 cds that came with the Dell where you have to figure out which ones and which drivers and do I have the license. Just install, or archive done. It really is better.
Thanks for the clarification. Naturally I just did not understand the word and it turns out 'oho' is the polite response. If I was not clear in me previous post I really did enjoy visiting Helsinki. I thought that the Finns were perfectly polite. Reading this thread it might just be that I am less polite than my culture would prefer and I am comfortable with the Finnish standard of etiquette.
I had the pleasure of visiting Helsinki for work for 6 weeks in deep winter. The Finns are terrific. My favorite mannerism is when you get bumped on the sidewalk which is of course very icy, in the morning walk to work crowd, and fall on your behind. The polite response is a half laugh/cough "Ho!". No help up, no sorry, just "Ho!". At first, when it was me, I thought it was personal and rude. But I saw some poor lady get exactly the same treatment. Everyone was treated the same.
During the same trip I saw the Gulf of Finnland freeze. First salt water body I've seen freeze. And the Finns were thrilled because now the drive to Tallinn was a mere 80 mi round trip, and the booze in Tallinn is tax free.

I understand non local hidden variables to imply information traveling faster than light. And another/. article talks about an experiment along those lines. But today based on what I know, I'll say that information doesn't travel faster than light, and that quantum events are in fact truly random and not based on hidden variables.
I'd need something stronger than 'does not rule out' to change my view.
You are not the only one bothered by the randomness of QM.
Some Physicists feel that QM is just hiding variables that are not in fact random, but they are currently a minority. The current majority view of QM is that measurements are fact random and no hidden information would explain away the randomness.
See http://en.wikipedia.org/wiki/Hidden_variables for more info.
I personally found it difficult when learning QM to just trust the math, but this trust is analogous to just trusting the data when you have an experiment that returns results you did not expect.
use " -D_GLIBCXX_DEBUG ".... I don't understand why everyone seems to know this part of stlport and don't realise other librarys have it as well.
First, thanks for pointing it out. I did not know about it either, and I try to read the docs. But also try to Google GLIBCXX_DEBUG. You will not get many pages, and I do not see any link to GLIBC or GCC docs that tell me all about its features. If you Google stlport the first link will tell you all you need to know. Here it is: http://gcc.gnu.org/onlinedocs/libstdc++/debug.html Ok, seems obvious now...
Yea, it was my first real job straight out of high school. It was an unbelievable education in software implementation; compilers, object language, and platform independent interpreters. I actually now work with two of my old friends from Infocom at a totally different kind of place. The IIe was a fine machine!

143K was standard, but 160K was possible. I wrote a modified RWTS when I was at Infocom so that we would not have to disk flip. Each track on the disk had 16 sectors by default, and since it was 'soft' sectored, there was a large header in marking the start of each sector. By making each track one sector I was able to recover that space and make it usable.
BTW - Infocom games ran on a ZVM - Zip Virtual Machine. The small one was 128K of virtual memory runnable on a 32K Apple. We were able to go to a 256K VM with the Apple IIc.
I still have my II+, and on rare occasion fire up Repton; the Sirius version.
...15 petabytes of data per year... [This] would be the equivalent of all of the information in all of the university libraries...
I suspect that 15 petabytes of data will actually be equivalent to at most a 2x the information in a number of standard model journal articles and texts. They just have to figure out the right compression kernel.
Agree with Parent completely.
In the early 90s I was doing some VRML work and I was shown the future of media research by one of our collaborators. They had created a virtual library. You started in the lobby and had to take an escalator to the second floor. I've seen more bad UI than good in my career but that was special.

I've used Retrospect since 1990. Terrific product. So good I haven't had to buy an update for years. Probably why Dantz was bought.

Better than what I thought, but I would also bet that not every shell explodes.
Don't forget, the bullets will come back down. In an urban area this could be problematic.

I never had a chance to program the TI-99. I learned asm on SWTP 6800, bought a PET, and then thankfully a II+.
Yea, it was my first real job straight out of high school. It was an unbelievable education in software implementation; compilers, object language, and platform independent interpreters.

Into a few relatively number of equations and descriptive text, yes.
I suspect that 15 petabytes of data will actually be equivalent to at most a 2x the information in a number of standard model journal articles and texts. They just have to figure out the right compression kernel.
