Usually a young person can handle 100% pure oxygen with no problems for up to 24 hours
I find this hard to believe. Everything I've read indicates that pure oxygen begins to cause brain damage within a few minutes. A quick search led me to this link, which is more recent that the 1998 study that I had previously read (which suggested that 4 minutes was just about safe and anything beyond that could cause brain damage). After 24 hours, I'd expect to see permanent brain damage in any animal.
I anxiously await the magic battery, but these global warming religeon people want to stop using fossil fuels right now. That's my point.
No, they want to start stopping using fossil fuels now, rather than waiting for them to be prohibitively expensive to do anything with and then have a mad dash to switch an entire planet's infrastructure over. Those crazy people.
Current electric vehicle ranges are more than adequate for a large percentage of the population. The UK has the longest average commute in Europe, and it's 8.5 miles each way. Something with a 50 mile range on a single overnight charge would be enough for all except holiday travel for any of these people, and they could always rent something with a longer range for big trips.
I say we work like crazy to invent the magic battery. After that, the CO2 emissions will take care of themselves, with the help of clean-burning natural gas
No, because replacing the cars is not the only thing that you need to do. You also need to build the charging infrastructure. If you can get people using EVs for short regular commutes now, then that encourages people to start rolling out charging stations across cities and installing them at home. That makes the next generation of EV more attractive.
Oh, and what makes you think that people aren't working on the next generation of batteries? That's a huge research area! Lithium-Sulphur batteries have come a long way in the last few years, and even NiMH cells have about three times the energy density that they did a decade ago and cost a fraction of what they did.
See, this is what happens when you start publishing statistics about the most active commenters. People like the parent try to get to the top by posting single sentences that look like they were constructed by markov chains.
As the original poster in this thread phrased it, it's racism (if you count 'asian' as a race). It's a racist remark if you extrapolate from a small sample to include every member of a race. Saying 'asian people cheat by all copying each others' work' is racist. Saying 'groups, often of asian students, form and all copy one person's work' is an observation.
Not necessarily. It could mean that it always raises your result, but some people shouldn't even have got in in the first place so need help to be at the bottom.
That said, I've taught a couple of university courses (in the UK) and I found that the weakest students were the most likely to copy someone else's work. When students are stuck, they ask someone for help. Some of them asked me, others asked their friends. Students tended to form friendships with people at a similar academic level. If a stronger student asks another one for help, he'll probably get given some advice, and talked through the general problems. Among the weaker students, their friends didn't understand the material well enough to provide advice, so they'd just show their own work. You'd then get two students submitting almost identical wrong answers.
Of course, the better students may also have been cheating - they were just better at it, and were cheating by some mechanism other than just copying someone else's assignment. Some of them were cheating by turning up to lectures, paying attention, and asking intelligent questions...
Some UK universities reported a problem when I was doing my PhD that relatively rich people in south-east asia would hire someone to do a degree for their son. This person would turn up, enrol in the son's name, do all of the course, and then send home the degree certificate. The son would then get a job with none of the knowledge or understanding that they were supposed to have and people would complain to the university. A few got caught because the employers sent photographs and they didn't match the ones in the student database, but it's difficult to spot.
IP does have a broadcast address. Packets sent to 255.255.255.255 would, in theory, be sent to every machine on the Internet. Routers block them because it would be make a DoS on the entire Internet trivial if it were routable, although you can typically use the broadcast address on the local subnet (e.g. 123.123.123.255). Broadcasting a packet to every machine wouldn't do you any good though, they'd need something to receive it. What do you have running on your computer that will listen for UDP packets (it's broadcast, so it can't be TCP, because that requires replies) and notifies the user when one is received?
Umm, no. This works precisely because TV and radio are push media. If there is an emergency, it is easy to push emergency broadcast information to everyone. The web is a pull medium, meaning that you can't get any information unless you know to look for it. They can't just inject 'aliens are invading, please go to your local soylent green factory immediately' into every HTTP request.
I have one of Sun's cheap workstations - the Blade 100, which was 100% cheap commodity crap plus an UltraSPARC CPU. The problem is that they don't have anything like the economies of scale required to make cheap chips. If Intel is selling 100 chips for every one that Sun is selling (which is quite optimistic for Sun / Oracle), then the unit cost of the SPARC is going to be a lot bigger, even if the two chips are the same size and made on the same process, just because all of the one-off costs (including R&D) are spread over a much smaller number of chips. A cheap Sun workstation is still likely to be a few hundred dollars more than an equivalent x86 system, even if all of the components other than the CPU are the same, and that limits them to people who really need to be able to develop on SPARC...
The same for Safari. The browser and the rendering engine run in different processes with recent versions of Safari, so you have to add the two up. 194MB sounds very low for both...
Nope, never called them, and never heard anything good from people who have - I'm not recommending buying Oracle, just outlining their thinking with regard to the Sun acquisition.
I don't think Oracle is interested in this market. They wanted the subset of Sun hardware that is good for databases and web apps (i.e. the Tx line), but they aren't really interested in being in the general-purpose server market. They want to be able to control the entire stack from the hardware to the applications, and everything in the middle. There are two reasons for this. The obvious one is that it lets them really tune for performance out of the box. The second, and more important, is that it lets them offer support contracts for the entire machine. If anything goes wrong with it, hardware, operating system, database, or in the business apps, you won't get your in-house IT staff to fix it, you'll just call Oracle. These contracts can be really expensive, and still seem like a good deal compared to keeping a few admins on staff.
I suspect that, in JavaScript's case, it's because there are a lot of things that can go wrong. In C, once you understand pointers that's 90% of the difficulty gone. With JavaScript, you have weird quicks of the scoping, strangeness related to the semicolon insertion and the bizarre binding behaviour of return, and that's before you get into browser-specific quicks and DOM weirdness.
Aside from performance, supercomputers generally have a single system image, rather than an OS install on each node and some middleware to handle job distribution. They also usually implement distributed shared memory in hardware, so they appear to have a flat address space and will move data around between nodes depending on which ones are accessing it. They may also have coprocessors for things like MPI messaging. And, as the other posters said, they have very fast and very low latency interconnects.
And THAT, that right there, i think is the REAL problem. too many have turned to PCs, DVDs, game systems etc as cheap babysitters rather than as useful devices that can help their child learn.
And there we have it. In shocking news, children who don't interact with humans grow up to be adults who have difficulty interacting with humans.
And AmEx can afford to do this because they charge a higher percentage of the transaction than Visa or Mastercard. This is why they are less likely to be accepted anywhere, and why Douglas Adams described it as 'a form of payment not accepted anywhere in the galaxy'.
If you really want to do banks in, use cash for everything
Yes, I'm sure the banks would hate this. Imagine if the bank could only charge the cash handling fees, rather than having visa / mastercard take a cut of each transaction!
They're not the only option. Islamic banking doesn't have mortgages: the bank buys (part of) the house and you rent that part from them, gradually buying back their share. Housing cooperatives do the same thing, but without so much centralisation: a group of individuals put up some money and jointly buy a few houses. These are then rented out and the individuals get a share of the rent, which is often then reinvested in more houses. Eventually you either cash out and buy a house, or you take personal ownership of one of the houses (or you just move into one and pay rent equal to the amount you get back, so you effectively own it but don't legally).

I've catched students cheating
Was it an English exam?
You're assuming that GPA correlates with intelligence. I'm not entirely certain that is a justified assumption.

In that case, your perspective on what constitutes crazy is probably not shared by the majority of the population.
It's a shame that it lacks one by default, but given that it's just two lines of code to add one to Object, it's not a massive limitation...

Yup, that's more plausible. It wasn't done because it was sensible, it was done because it was easy.
