For that matter, pointers in C is just one thing I can think of that's far more complicated than the difference between pre- and post-increment. That's a necessary complexity, though. All the smartass little shortcuts C has built in don't actually make it more efficient or let it do anything it otherwise couldn't.
And yes, there are compiled functional languages with parallelizing compilers. (Erlang and OCaml come to mind) If we're all about to have extra cores to throw around, I don't know that compiled vs. interpreted will matter much, anymore.
Both Japanese and American submersibles were better. For instance, German submersibles were strained to spend six weeks at sea without replenishment, unlike American or Japanese boats. That's just a matter of requirements. Japan and Hawaii are a long way away from each other. With England right there, Germany could build smaller, cheaper submarines that were harder to see.
No, in fact, the magnetic fuse was NOT universally used in WW2, by any side. It was, in fact, a relatively late development. Most torpedoes went boom when they hit the side of a ship. Or not, in the case of the American torpedoes. I've read many places that the American torpedoes at the beginning of the war had three problems: The magnetic fuses rarely worked. The contact fuses would be crushed without going off if they hit something head-on. They ran too deep.
I've read fewer places that the magnetic fuses were a copy of a German design, but the Germans decided they didn't work and abandoned them pretty quickly. I read Günther Prien's book about the sinking of the Royal Oak years ago, and I think he mentioned problems with the magnetic fuses.
I know torpedoes explode under the ships now. Do they have magnetic fuses again, or do they just use the sonar to decide when to go off?
Absolutely. My car has a knob with internal circulation, middle vents only on one end, and defrost/defog with and without floor vents on the other end. The air conditioning comes on automatically with both internal circulation and defrost.
I frequently do want the A/C on with internal circulation; that's the best way to keep it when it's hot out. I also want it blowing at my feet, though, and that's not an option. And sometimes I'm not hot, but just driving behind a stinky car.
You may not realize how much running the compressor helps because you you have not experienced one that did not run on defog. I drove a 94 SunBird without air conditioning for a little over three years, and it was fine. I occasionally had trouble keeping the windshield unfogged, but only when it was both very humid and it had been more than six months since I'd washed the inside of the windshield.
My 2004 SunFire does turn the air on for defrost/defog, and it doesn't seem to work any better (I know the theory, and I'm sure it *is* better, just not enough to make a difference). It just makes me feel guilty about running the A/C when I don't need it.
Especially annoying was that it would shift gears for itself, which meant it was often not in the gear I wanted (which is a problem for low-horsepower cars like that). Granted, I normally drive a stick so I don't have a lot of experience, but how else would an automatic transmission work?
to understand pointers, or why they can come very handy, you should rather learn some theory about trees, lists and so on. You don't need raw pointers to do that; object references will do fine. I've actually done AVL trees in Visual Basic 6.
If there's a university CS program that gives degrees without courses in Operating System and Compiler design taught in C, I'd love to hear about it. My operating systems class wasn't really a practical class. We basically just talked about all the things operating systems do and how they affect your programs and whatever else is going on in the computer. I think that's normally how it's done unless you use Tannenbaum's book and study Minix.
We have a compilers class (Programming Language Implementation), but it's an elective, and while I'd like to take it, I'm graduating in December and it's not offered before then and hasn't been for at least a couple of years.
C is probably not going to last. But its successors, C++ and C#, will. C# is an application language that happens to look like C, just like Java.
I really would like to see a systems programming language sometime that didn't have C's nasty cryptic syntax. I realize a lot of people like that syntax, and I'm not saying they're wrong, but more than one choice would be nice.
The main reason for the longlevity of COBOL -- it was the only language that could do fixed point arithmetic correctly -- will no longer true as C, C#, C++ Java et al. are finally going to get built in support for decimal arithmatic sometime this year. I got a job in 1997 (straight out of dropping out of college) maintaining old MS QuickBasic programs. QuickBasic (or at least the last professional version, which I was using) has a Currency type, which was a 64 bit integer offset by 10000. I believe all versions of classic VB had this as well, and I know for a fact that VB5 and VB6 do.
Of course, how many complaints have you heard about VB being the new COBOL?
When people cant think properly because they've taken too many drugs This one is valid, although I'm inclined to think that someone using drugs (including alchohol) that irresponsibly is likely to do other things just as irresponsibly.
The rest of those are largely problems because drugs are illegal.
What about offering GMail to companies for their own employees? I understand most companies wouldn't want Google hosting their data, so how about a GMail appliance?
I try not to do it often or with anything sensitive, because again, I know my company probably doesn't want Google hosting their data, but when I really need to be able to find something again, I send it to my GMail account. There, a single search will bring it up in under a second, vs. a 20 minute search through Outlook that may or may not find anything (when we were on GroupWise, it was more like five minutes, and it would be found).
What about my argument that T-SQL is a horrible language? You have one looping construct and one statement level conditional construct. Cursor loops require you to write the FETCH both before the loop and at the end of the loop making maintenance that much more tedious. Compile errors can be tough to track down as the messages are often vague. Hidden gotchas like compiling a procedure with QUOTED_IDENTIFIERS on and modifying it with them off are always fun. No select construct (as in a traditional programming language, not record selection). Until the latest version, no exception handling.
Yes, T-SQL is pretty weak if you look at it simply in terms of a procedural language. The context of execution is right there with the tables, though, and it's just one language, which is pretty nice compared to an application language where you have to connect to the database and pull stuff over, or PL/SQL where you have to keep track of what's SQL and what's PL/SQL, and do inane things like "Select SqlFunction Into Variable From Dual;". Table variables are a glorious thing, too.
And I spent two years or so doing most of my work in T-SQL before we started moving towards a Java web services architecture (we didn't know where we were going, but we knew we wanted to avoid writing more VB6), and in that time or the year or two before it, I never wrote a cursor loop (I used this technique.). I also never wanted run-time ordering of records, but that's because I'm more of a back-end guy. If there was a screen where the user could select the ordering, my instinct would be to do that in the recordset.
Yes, T-SQL has plenty of weaknesses, but don't pretend the alternatives don't. It can be more frustrating, because T-SQL's weaknesses seem like they'd be easier to fix than those of the alternatives. User-defined functions in SQL Server 2000 and error handling in 2005 were good steps, though.
My instinct was that the pressure would force water into its densest possible form, and that wouldn't be the kind of ice we're familiar with here on earth. Yes, you answered that, thanks.
How about true art training? Studies (which I don't have a link to) have shown that kids that are taught to draw realistically tend to do better in ALL subjects If there are any near you, it sounds like you might like a Waldorf school.
If the pressure is keeping it solid, would it also keep it from forming the crystal structure that makes ice less dense than water? Normally, pressure (say, from an ice skate) turns ice briefly into liquid water.
I think, anyway... This is going back to my last chemistry class in 1994.
the only unsolicited calls you will get are 1) politicians (of course), 2) companies with an "existing business relationship" with you (that's interpreted loosely sometimes), 3) charities, and 4) pollsters. That helps on the volume, but charities were always the worst of those calls, anyway.
The point of representational democracy is that the representative THINKS and VOTES their own beliefs, as a representation of what the their constituents want. It is their responsibility to understand their constituents and represent them. This is not what politicians do at all today - politicians primarily represent their party, mostly for financial reasons.
Right. I think we should end the charade, at least in the senate. We should be voting for a party, who gets a proportion of the senate vote proportional to their proportion of their last general election votes. The party has one group of employees who do campaigning and another who show up to the senate.

Depending on what you've got in the dryer, you may want to fold it while it's still warm to avoid wrinkles.
Especially annoying was that it would shift gears for itself, which meant it was often not in the gear I wanted (which is a problem for low-horsepower cars like that).
Granted, I normally drive a stick so I don't have a lot of experience, but how else would an automatic transmission work?
I always wondered how they intended to display that message.

How do people without land lines find their cell phones?
Ah, Slashdot is fun. It doesn't even occur to people to add the caveat "single".
We have a land line, but when one of our phones gets lost, it's usually in the car. I take my wife's cell phone out with me and call mine on it.
