Re:How can they detect anything at all?
Yes, in fact I have. There is lots of information about neutrino oscillation. But the particular information that I was asking about, that is, the cause of neutrino oscillations (which you would know if you had actually been paying attention rather than being a snotty smartass), is not, to the best of my knowledge, to be found there.
Lots of information about how they oscillate. Or possibly how... that hasn't been proven yet either. A good source of information about that is Paradoxes of Neutrino Oscillation by Akhmedov and Smirnov, which illustrates that even that part of the issue is very much in debate still, and hardly settled or known as you imply it is.
So, if you are going to respond to a question at all, why don't you try answering it, if you can, rather than just being snide and insulting about someone even asking it? -
Kid's Programming Languages
Unless they're vaccinated, don't give them MUMPS; if you do find a nice Doctor (Like Dr. Pascal), 'cuz Pascal was fun for me in College.
If they like noises, Squeak is good, but the cogently verbiaged might prefer SmallTalk in a group. For those speech impaired, knowing there's other people who Lisp would be good.
The mean ones will abuse Snobol in Winter
The A.D.D. kids will probably like the feeling of Euphoria they get from their first
Of course, you could teach them a very nice language with a horrible name, Brainfuck.
Or, you could just look Here for a comparison of popular programming languages. -
Re:BSD license
One of the reasons could be that Yahoo uses and advertises FreeBSD since they started.
I know at least 1 giant company started using FreeBSD because of Yahoo. "It can handle entire yahoo userbase" is really a huge "selling" point.

Do Zero Gravity Here
Using intense magnetic fields, it seems that it is possible to counteract the effects of gravity here on Earth. This is much less expensive than going to outerspace. How come NASA hasn't dumped billions into this technology?

Re:How not to write voting software
(sorry man, short in C/C++ only goes up to 127,
You're thinking of pascal.
Check this document. Seems that a short is declared to have 2 bytes available on solaris, but it's really by vendor. So you can't say "you only have 127." It'd be kind of stupid to limit a short to 8 bits when a signed char will accomplish the same thing. -
Companies that use open source
Google is built on Linux, Amazon is built on linux, Yahoo is built on FreeBSD and Salesforce is built on Linux. Perhaps if you did a few searches you might be able to find some intersting articles. For example I found a page about Yahoo & FreeBSD

Excuse me, but Yahoo! uses FreeBSD
a 'layer' above Linux, Windows or Mac OS
Someone had to point it out...
I know, MacOS was born out of FreeBSD, but it is not the same thing, and I don't believe Yahoo! is using it anyway.

Re:No wonder you post anonymously.Previous poster called:
" Bullcrap "
on another anonymous poster's claim that Yahoo's continued FreeBSD use is merely a legacy decision.In all fairness, that article appeared in issue one of the FreeBSD News, circa 1997. That's not a good or honest way to disprove that Yahoo's ongoing use of FreeBSD is a legacy decision.
Reading FreeBSD postings from a Yahoo engineer's blog is an excellent way to understand FreeBSD's strengths and appeal, however. Doesn't look to me like they're itchy to migrate.

Re:Answers to the aboveApparently Linux doesn't preload applications, though BSD does. See this little note about a Linux preloading experiment, which reduced the launch time for Netscape Communicator from 14 to 4 seconds by reading the whole executable in at startup. On the desktop, that's probably a win when the user launches a program, since it gives the most resources to the program the user wants right now.
But that's a brute-force approach. A better solution would be to profile applications, feed the profile info into the linker, have it put the most-used stuff first, and put a hint in the executable that indicates how much needs to be preloaded to get through the first few seconds of running without a page fault. That would lead big improvements in application launch times.
The Wind River DIAB System does things like that. So does Sun Workshop. But I don't see the Linux world doing anything like that yet.
I see the point about mod_perl. mod_perl is essentially a way to move some loading and memory management from the OS to the web server. If the OS were good enough at transaction processing and program initial load, the need for mod_perl would be much less. But mod_perl is a good tradeoff, because most CGI scripts are tiny. The poor program load performance inherent in a load-by-page-fault approach may have driven the server world into that solution. mod_perl, after all, was developed as a reaction to slow CGI program load times.
