I have tried the save image method (that was the first thing that sprang to mind for me) but on the implementations I tried (CMUCL & CLisp) it is exactly as you say: the image is there, but the traceback info is not. Even simply printing the traceback to a file is better than nothing, but its a read-only solution. I tried with python as well, with pickling the actual traceback object and writing that to disk, but I also ran into problems.
I hadn't thought of forcing the OS to dump core for me, but unfortunately the problems with this would be twofold: First, as you say, finding a debugger that can make any sort of sense out of the core may be tricky. Secondly, you wouldn't just get an image of the running system (as you would in C) but rather an image of the interpreter + system.
2f) debugging and testing with the read-eval-print-loop (REPL).
Ok, perhaps someone can clarify this for me. I really like the features of lisp & derivatives, and some other higher level languages (python comes to mind) for debugging "on the spot", and not getting core dumps. But, my question is, what about when you *want* a core dump? I'm talking a program that is "allowed" to crash (ie people won't die) but shouldn't be "down", sitting at a interpreter/debug prompt waiting for you to figure out what caused the crash. Something like a web server or other network service that may crash at 3am and be down for several hours, or automatically restarted, but then you lose the "core" -- the complete image of the system at the tmie of the crash. The nice things about coredumps in this situation is that you can restart your service automatically, and still have a complete memory image of the problem for post-mortem debugging. Can lisp/scheme/python/whatever mimic this system? Or, am I just thinking in C mode and is it a non-issue?
Ya know, its inevitable that someone will bring this up in any slashdot story on either opensource or microsoft. I think we need to have a "law" about it, and I'd like to suggest that it be named after me.
(C'mon, please? I've never had a law named after me before.)
Well, thats almost right. The ships were belgian and french, not american. One of the anchors from the ships is not too far from my house (but several KM away from the harbour:)
The reason liberal voices aren't heard is because NOBODY WILL ADMIT TO BEING LIBERAL! Liberalism is dead. It failed. Deal with it. The debate now is between Neo and Classical conservatism.
Liberalism is far from dead. In fact, the neo-conservatism you mention (which is a horrible misnomer, btw) has a lot in common with classical liberalism. Just about everyone in the western world is a liberal of some manner, its just a rarely used label nowadays...like you say, no one will admit to being a liberal. Its actually classical conservatism that's commonly accused of being dead (and that shares a lot in common with *gasp* socialism. Really).
It is now belived that 30,000 years ago, it was neccessary for only the adult members of society to work only 15-20 hours a week for all survival functions--I'm not suggesting we go back, but it certainly makes you wonder...
Yep, but it wasn't that it was necessary they only work 15-20 hours a week, it was necessary they work at most 15-20 hours a week. Due to the ins-and-outs of hunting/gathering, any more than that and you're expending more energy than you're taking in. Most of that "leisure time" was spent actively doing as little as possible..no energy to spare.

This already exists both in paris, and certain parts of Mexico City.
They're in a lot of places. Most places I've seen, they exist mainly to keep homeless people from sleeping and/or shooting heroin in them. The ones I've seen are actually really clean...
"I" is possesive, and suggests that he himself was the one who did this. He could have said "We took the initiative", or "I urged other congressmen to take the initiative", but he didn't. He claimed sole responsiblility for an act which he played a very small role in.
Yes, except in this case, the "I" is referring to who it was that took initiative, not who created the internet. I can say "I took initiative in doing my homework" by giving someone else $10 to do it for me. Did I do the homework? No. Did I show initiative? Yes.
Gore did claim to have invented the internet, and I suggest you learn english.

You're just another one of those Linux-zealot Microsoft bashers spewing the party-line on Slashdot in order to gain karma.
Come on, that's so last year. In order to gain karma these days you need to say whatever is against the perceived party-line, and complain about how all the moderators will moderate you down for being so avant-garde.
Odd, the same thing could be said for Europe or Canada, yet they offer considerably more freedom than Singapore. Could it be that this be the result of guns alone being banned???
I live in Canada, and even in my relatively small city there are plenty of places I won't walk around in at night, or even drive through. There is a difference between guns being banned, and guns not existing.
And, BTW, "guns" aren't banned, but you do need a special license (read: a real good reason) to legally own a handgun. Automatic weapons are right out. Even so, a number of kids in my old highschool had handguns at home, and automatic ones at that...My old highschool was the one that all the kids from the rural areas outside of town went to though, and I'd be surprised if 75% of them didn't have a rifle or shotgun at their house.
That said, the rules have recently changed, and I'm not sure about them now, but I think you now need a license to possess firearms of any kind. I don't hunt, nor does anyone in my family, so I don't know for sure. I think that in order to get one of these licenses you'll need to pass a test (likely about as difficult as a driver's test) and probably need to be a certain minimum age. Then you can walk down to your local Canadian Tire and pick up a shiny new rifle. Now, rifles aren't nearly as convenient as handguns for sticking up the 7-11, nor for hiding in the dark and mugging someone, but they're just as good at killing someone.
In short, just because it's banned doesn't mean it disappears. I'm farily certain that even I could buy myself my very own illegal handgun fairly easily. And if I was the type of person that wanted to own a handgun, the possibility of the fine for getting caught with it probably wouldn't bother me. Banning something doesn't do anything, you need to back it up with *real* punishment in order to make it work.
It also holds together Steve Austin, the Six Million Dollar Man. Where would the entertainment industry be without the advent of the Bionic Man and his accompanying sound effects?
Whew. Good thing we didn't have this technique back then. The $19.95 man doesn't have quite the same ring to it.
I especially like the "hack" to open a Master combination lock.
One of the more useful articles I've ever read. I never bother memorizing my lock combinations anymore,
I forget them after only a few weeks if I don't use them, but I've remembered this technique for I don't know how many years. Works every time.:)
Three cheers for that idea! I've been wishing the demo scene would find some life even without the extra incentive of deterring script kiddies--demos are just plain cool!
I've been hoping for this too, but I fear it might be impossible. I don't mean we can never have a demoscene again, but we can't ever have a similar demoscene again.
A lot of the fun, for me anyway, was in the bare-metal coding. That's exceedingly difficult today. There was a certain charm to working directly with the VGA, it was a lot of fun, and a great learning experience. You can't really do the same thing these days, with the huge variety of video cards on the market. Besides, the reason it was fun was also because it was very primative:) Making a cube that rotated around with nifty plasma backgrounds was cool in '94, but nowadays....
Writing a demo in OpenGL, with "put a cube here, rotate it this much" isn't as appealing to me as the old way. It allows you to do way cooler effects, much easier, but its just not the same. There's something about doing the math for your own 3d effects that makes it more rewarding, IMO. But, I'm just a tired old crank who's sick of programming anyway. Less API, More Math!
Does your college allow you to acquire a minor in a field of study? If so, then I'd suggest turning your three years of CompSci classes into a minor in CompSci, and then do something completely unrelated for your major--something that you enjoy.
*Blink*
Why didn't I think of that? I think I'll do that. Thanks:)
Having taught at a top-10 university in CS (I taught a physics course the CS program used as a "weed out" course), I would have to add "...and if you don't get any joy out of learning material that isn't directly related to coding for cash, if the only compelling reason for your being in college is to make making money easier, then go out and do it. Don't waste your time with college."
What if you take a great deal of joy from learning for everything except the courses that are directly related to your field. I'm serious:)
I spent 3 years in a CompSci program, and just recently dropped out. Not because it was too hard, but because the subject matter simply doesn't interest me at all, presenting a serious problem. I really enjoy working with computers, and I have since I was 13, but I find it very, very difficult to pay attention in the classes or do the assigned work. I got through the first 2.5 years by skipping classes often, doing half-assed jobs on the assignments, and doing well on the final, but when I do that I feel like I'm ripping myself off, instead of the usual "the university is ripping me off" feeling.
I've been considering going back to school in a very non-computer related field (I was thinking some kind of arts degree, maybe), but I still don' know what I want (and the parents are getting restless). Anyone have any ideas?:)
I would be hard pressed to find a worse reason to select an OS to use for any purpose.
Sheesh, quit being so pragmatic. If everyone picked their OS based on technical merits, linux wouldn't exist as it does today. Remember what linux was like back 5 or 6 years ago? When it took a good week to get the whole thing downloaded from a 14.4 modem (it'd always disconnect as soon as I went to bed) and actually installed? When most of your hardware wasn't supported? But when you actually got it to work it was cool. And thats why I did it, and why a whole lot of other people did to, which is why they contributed to and supported their favorite little underdog OS and made it into what it is today.
