Yep. The Cray C compiler is this huge, slow, stinking mass of algorithms designed to figure out what high-level process (sorting, matrix multiplication, etc.) you're trying to write in medium-level C code, and then it drops in fine-tuned assembler code and makes a few substitutions, and, voila, your app runs on a multiprocessor supercomputer.
There's no reason a very well-engineered language aimed at solving the majority of common computer problems very well couldn't have a syntax where the compiler always knew what the programmer was trying to do, and could simply spit out bytecode corresponding to the different abstract steps that the program goes through; the interpreter would execute highly-optimized native routines, and this setup would easily outperform standard compilers for most tasks.
Of course, designing these types of programming systems is very difficult, indeed... but, to some extent, it *has* been done, there just aren't very many options yet...
Well, I know a very bright person who tends to vote for Democrats, but sides with Republicans when it comes to welfare, because the welfare system is fucked up.
You _should_ have gotten some kind of welfare. You are obviously a very capable individual who needed some momentary (no pun on "monetary" intended) and temporary help! A lot of Republicans denounce the Democratic Party over welfare, saying it doesn't work as it should, but, the Democrats answer back with, "Well, it would work, if the Republicans didn't mess it up.
*shrug* People who need help should be able to receive help if they take some effort to help themselves... and people need to be made aware of the resources out there so they *can* help themselves. You know?
Your story is a very interesting one, I will probably remember it for quite some time =)
Yes, but that was in a day where name, honor, and trade were closely tied. Nowadays, I don't have to be a chip off of the old block, hence, I shouldn't be chained to the old block, either:)
Well, yes, that seems to be true. I think, because of the recent international affairs, there has been a push for protection within the conservatives; normally, conservatives favor a small government for big businesses and low taxes, but threat to national integrity and economy seems to have made a temporary change in this, at least as far as intelligence goes. I think the Democrats have reacted to this, much as they would to most everything the conservatives do, but it has the advantage of extending the "liberals" to include not just the Democrats but also libertarians (whatever that may count for). *shrug*
It's not about creating a permanent underclass or some other conservative propaganda. It's about how some people a few centuries back fucked up really badly and were extremely unjust, and we're still trying to fix the mess from back then.
Many of us _are_ descendents of those people. It doesn't make it our personal responsbility, because, a child should not be held accountable for his/her parents' crimes, but, it does make it a responsibility of our society. Of course, I don't think the government should be big enough to run its own welfare program, but I think there ought to be a few non-profit organizations doing these and getting free access to private and government resources beacuse of it.
"Helping yourself" my ass. Saddam Hussein and Usama bin Laden both help themselves to what they want. Not to suddenly start trolling, but, is helping yourself and turning a blind eye to everybody else really the best thing you can do for society? If you are truly *helping yourself*, you realize that you are a member of society, and it affects you. Ignoring problems is only going to perpetuate your daily headaches. When there are inner city teenagers (I'm not implying that these are only black people, mind you; there are plenty of white, Indian, Native American, Hispanic, and micro-Asian people who need help!) working at McDonald's who don't give you correct change because they don't have basic math skills, *That Affects You*.
I don't like the liberalist propaganda I hear about how the government needs to be very big and intrusive in order to take care of its citizens. I can take care of myself; I don't really need to be watched, except for the occasional helpful police officer (but in some parts of the country, helpful and peace-promoting ones can be hard to find; but I digress) to make sure I don't get too pissed off and do anything stupid and nobody else does anything really desperate or violent with me as a target. But, on the other hand, I can't take the stuck-up attitude pervading the conservative propaganda. If the stuck-up republicans (which is actually *not* the majority of republicans, but they do seem to be the ones that open their mouths the most) shelled out the money to make most college education free, society would get a lot better very quickly. Some people with money do create scholarships and foundations to aid education (for example, this is the only context where I actually take a liking to Bill Gates! Not sure what his affiliation may or may not be, though), but, more ought to, rather than complain how much they're getting taxed.
Hoping I don't get modded down for getting too political on/. --- although it IS on topic just this once...
Hmmm, good point. It's a lot easier to screw around with computers, though. Plus, many people don't take them too seriously. I mean, after all, it's just a hunk o' machinery, right?:P It's just like a microwave that talks to other microwaves, how much harm can you possibly do?;)
Not if your car is a webserver. That's like having a car with a big sign that says "LOOK IN THE WINDOWS! THERE'S COOL STUFF INSIDE THIS CAR!" Of course some people are bound to try the handle, at least to get a closer look. I attempt anonymous ftp logins and try/pub URLs on webservers all the time, as well as ascending to the parent directory and such. Sometimes I find some really neat stuff that way. I'm not about to attempt a root login, but, it's human nature to explore and try things which may or may not be OK, unless there's obvious immediate harm. If all humans were extremely cautious and thought hard about consequences and ethics, the US would not exist, and the natives would still be abundant.
Oooh! What's funnier is having different root passwords for every machine. Ooooh, and what really gets me cracking up is when I set it up so only a select group of users can 'su'!
Don't even get me started on setting up ssh so you always have to enter your password! Oh man! I'm rolling! ROFLMAOLOL!!! OLOLOLOLLL!!!

Hmm... well, I'm going to friend you, because you seem friendly, and because maybe I'll get lucky and you'll post the answer to all my problems in a comment somewhere on slashdot;)

Man, I wish I had this guy's problem. I have problems sleeping too MUCH. I have trouble getting to bed some nights, but usually, after 8 huors of sleep, I have trouble getting out of bed. Sometimes my blood pressure is about 70/40 mmHg when I wake up and my pulse is about 40BPM (my physician's best guess is that my body slows down so much when I'm asleep that I don't get enough oxygen). I never have the energy to do anything. I'm young, in fairly good health, get some regular exercise, eat a mostly balanced diet, and I'm careful about my caffeine intake. I'm really stumped about how to fix it.
Except I don't post a bond, because I - can't afford the huge bond required by someone who is in some sort of big-money clique - had my wallet stolen so I won't be using a credit card for the next 6 years - am under 18 - need complete anonymity - am very poor and lucky to have e-mail by WiFi-on-a-bike etc.
I mean, I like the idea a lot, except for the fact that I really don't like the idea of my finances being connected to the Internet. I also don't like the idea of being able to do things with the Internet that an underpriveleged third-world person or minor wouldn't be able to accomplish; I don't want to be priveleged or lucky, because, what if someday I don't find myself priveleged anymore? And how about all the kids growing up on the Internet right now? I was a kid myself, once.
But this problem was already solved. You could have already had a whitelist if you wanted to, and the behavior would have been very nearly the same.
However, if you used a whitelist, mail from people you don't know (new e-mail addresses for old friends who forgot the passwords to their accounts, for example) never makes it. With the new system, nobody is going to want to pay money to have their e-mail potentially just marked as spam anyway (And, yes, I do realize that the recipient can negate the charges to the sender), so they won't bother to contact new people. New communication is stopped at a different point, sure, but it's still stopped, and that's the problem.
I like being able to contact random people I don't know. That's the beauty of the Internet. If I find a webpage that strikes my fancy, I can contact the owner of the site to discuss the ideas on the webpage with him/her. I do not want to go away.
Great! Now all I have to do is print this out and take it with me to the grocery store, along with my X-ray scanning system. Then the prize is mine for sure!!
It was a significant speedup. These were actual processor opcodes. Granted, they took 2-3 times as long as other opcodes to execute, but, that's still less time than it took for the loop to run.
In the 80s, one of the big touted features of the 8088 over the 8085 (or was that the 8085 over 8080?) was the addition of so-called String instructions. Previously,you might do this: LEA SI, $src LEA DI, $dest MOV CX, #len MOV ES, DS copy: MOV AL, DS:[SI+CX] ! two instructions (DS: then MOV) MOV ES:[DI+CX], AL ! two instructions (ES: then MOV) DEC CX JNZ copy Notice that the copy loop is a significant numbert of instructions. But, the new instructions like REP, MOVSB, MOVSW, CMPSW, LOOPZ, STOSB, SCASB, and LODSW let you simplify the entire copy loop to: REP MOVSB
The processor could then very quickly and efficiently move the string. See a page about the 8086 for more info.
Until this bill passes, take a last few moments to enjoy these--- 1. Text editors with copy and paste features 2. Operating systems that let you copy files 3. CPUs (such as intel's x86 series) with built-in string-copying operations 4. Xerox machines 5. Printers 6. Cameras 7. Research papers that quote any sources 8. Cell Mitosis 9. Mass production 10. Gutenberg press
Then, prepare yourself for a moment of silence. In fact, prepare yourself for a lifetime of silence. Those words are in a copyrighted dictionary, after all.
It was in a quantum super-state. The act of observation (By clicking Read more...) made it evaluate to a particular single state.
