But you have to admit there would be much more overhead.
Memory management takes a certain amount of overhead. There is no reason, in principle, for this overhead to be greater or lesser using automatic memory management (garbage collection). The same work is done either way, the only difference is how it is done.
Its a matter of keeping track of what memory is not referenced,
The primary activity of malloc (since it needs to know this in order to hand out memory). Malloc just needs more hints from the programmer than automatic GC does. Supplying these hints results in a certain amount of overhead that GC avoids. We can spend all day pointing out things that one approach needs (and consumes processor cycles getting) that the other does not. Why anti-GC zealots seem to think this is a one-sided issue is beyond me. Manual memory management doesn't work by magic, either. It requires overhead and processor cycles...
and that takes a lot of work for a machine, where most other languages the programmer would take care of all that in the code (hopefully).
In other words, rather than it being taken care of in the code (of the compiler/environment), it needs to be taken care of in the code (of the application).:)
There are cases where manual memory management works faster than automatic, and there are cases where the reverse is true (consider how many cycles it takes to execute a "free" call vs. how many cycles it takes to not execute one -- some code will run faster under GC, especially a GC that doesn't need to visit blocks to free them).
No one has to "admit there would be much more overhead". It depends -- some cases it can be less, some cases it can be more, in principle it ought to be about the same amount either way (the same job is being done, the only thing GC does is switch who's doing it). A poor GC will be slower than well-optimized application specific code, which was a historical problem, but as the author of this thread said, it ain't the 70's anymore...
Check their website. There were a number of problems with the drivers for my keyboard originally (including incredible slowness), but downloading a newer version of the keyboard driver fixed them. Mine's on a IIIxe but I imagine the same is true for others...
Actually, I see comments like that all the time. "A lot of mathematicians were kinda nuts." "A lot of computer scientists are a bit off." "A lot of artists were insane." You know what? A lot of people are like that. More than most people realize. It should be no surprise, then, that when you study a particular segment of people that you find a lot of people are a bit off. This only seems noteworthy when you've failed to notice how common this really is in general...
Of course, all my friends are nuts...:)

Your egregious duplicity is undeniably annoying!
Whose duplicity? Which of the commenters here said it was okay to leave parts of this book out but said the opposite for LotR? Or are you one of those morons who still hasn't figured out that not everyone on Slashdot agrees on everything (or anything)...
There is nothing contradictory involved in one Slashdot reader saying one thing and another Slashdot reader saying the opposite. Your inability to grasp simple logic is undeniably annoying!
Translation for gamers: Many exceptional people are "minimax characters" -- "Oh, I can get all the attributes, skills, spheres, and backgrounds I want if I take this one -7 Flaw? Wait, can I get this -5 Flaw too? The rules say you can only have 7 flaw points but that's too limiting...":)
Cute picture, especially imagining my friends rolling up their lives before they were born (I have one who always makes these minimax type characters, and he himself seems to be one). But I've met too people with the virtues but not the flaws, or worse, the flaws without the virtues...
Maybe they borrowed or lent points from a previous incarnation...;)
I think you just have to wait for steady blocks of time to show up, or start fucking people over with an angry temper.
There are more diplomatic ways of telling people to leave me the fuck alone than saying "leave me the fuck alone"... One does not have to be an asshole to get some solitude...
It does, however, require bachelorhood or a very patient and understanding spouse....:)
Umm, I think you're confused. The ADL complains that the Swiss did business with the Nazis and profitted from it greatly, which is true. However, this does not "debunk" Swiss neutrality. Had they refused to do business with the Nazis, that would be an example of the Swiss not being neutral. The complaint here is not that the Swiss were not neutral, but rather that they were when they shouldn't have been. The ADL is unhappy that the Swiss helped and profitted from the Nazis, but they would not have been neutral if they hadn't helped and profitted from whoever wanted to do business with them. Your link only demonstrates that the Swiss were in fact neutral, and not on our side/against the Nazis.
I think you're having problems with the idea of neutrality. You think it's not a bad thing, you see the Swiss did bad things, and therefore want to say they were not neutral. But that is not the case. They were neutral, and what this example shows is how evil is can be to be neutral when one shouldn't be...
Agreed. I'd just add that actually, short stories are the right length to be turned into movies. Thus, almost any novel, unless it's really really bad, can be turned into a good movie since, considering you're translating to a format that's really more suitable for a short story, you can leave out all the bad parts of a bad novel and still have enough left over for a good movie.
Not that this is easy... just saying you'd have to start with a pretty bad novel to not find enough good material in it for a good short story or movie. (I've actually read a number of bad novels that would have been great short stories...)
No, it doesn't do anything even remotely similar to this. You know, if you don't even know what the word "process" means when used in a computer science context, perhaps you should consider not posting to a thread about freezing/thawing a process...
Not that this has stopped the majority of people posting here about laptop suspend/resume, VMware, and other completely unrelated topics.
This is a simple case of process migration. Of course, process migration isn't all that simple...
Galeon is definately the best browser I've ever used, and I've used quite a few since the NCSA Mosaic days... I have to admit, though, when I pull up the same page in Konqueror and compare side by side, Galeon is butt-ugly. On those occasions when Konqueror manages to render the page correctly, it's quite a beautiful thing. Unfortunately, it's nowhere near as usable as Galeon -- hopefully with GNOME 2.0 bringing anti-aliasing, we can finally get the best of both worlds...
This would not surprise me. Most people who actually have working systems doing a job know that, despite popular myth, computers don't become obsolete. They break down eventually, but until they do, they can still run all the software they ever could at the same speed they always did. If an Apple II was fine to do a job in 1979, it's still fine to do that same job in 2002. If the job requirements haven't changed, and it's still working, why waste money upgrading to something you don't need and throw away a perfectly good solution because some idiots think if it's not the latest and greatest hardware it's useless?
That's an impressive list of unsubstantiated assertions. Not that you're wrong (I have no idea if you are or are not), I'm just curious if you actually have any figures to back up your statements or if you are just blowing hot air...
Are you sure about that? I doubt very much you see red or green at a lower resolution than blue. This display should look crisper to you than a traditional LCD display, even if you can't tell the red pixels from the green pixels.
I was under the impression that more of us engineering types were affected!
Than the general populace, to a statistically significant degree? I find this highly unlikely.
It's not just you, that's how human vision works in general, and it's exactly the effect this new layout exploits. There are fewer blue pixels (which are therefore further apart) because our spatial perception of blue is less exact than of red/green. In effect, since we can't see the higher resolution of blue, why provide it? Having the same number of blue pixels as red or green is wasting a lot of pixels -- due to the "bluriness" in which we perceive blue, there's no point in having that many blue pixels -- we can't tell the difference between that and only having half as many blue pixels.
Are you sure? I recognize that she rules more than just England (Scotland and Wales come to mind), but I thought she still held the title Queen of England, as well as quite probably numerous others (anyone got a full list somewhere)?
If President Bush happened to concurrently be Govenor of Texas (not sure if that's possible, but if it was), it would be proper to refer to him by either title.
Now, happily for me, I didn't have this problem. This is good since I'm logging in remotely to my box in California from Spain, VIA SSH!! I'm an idiot as I've also shut off Telnet and if it DID segfault, I woud've been completely screwed.
I don't think so... doesn't sshd fork to handle each connection? You'd have crashed the process listening for new connections, but it wouldn't have affected your current connection.
If this isn't true, then I'm baffled as to how I've been accomplishing SSH upgrades on all my servers, few of which have keyboards, video cards, or telnetd running. I down and restart sshd all the time remotely over ssh...
As a side note, I don't think the Euro is such a wise idea for Europe. The states had the benefit of having far less economic unbalance at the time it decided to unify their currencies than Europe does right now,...
I suspect this problem will fade with time. There's going to be short-term difficulties, but in the long term it'll be a good idea for Europe. The problem was, it should have been done a long time ago. The longer Europe waits to do it, the larger those different economies are going to be when it happens, and thus the more painful a transition it'll likely be. But of course IANAE (I Am Not An Economist). I wouldn't bother to inject my opinion, not being an expert, except I don't believe economists are experts either, they rank somewhere below meteorologists and astrologers IMNSHO...:)
Why can't American dig up a politician at least half as good as Tony Blair? Any chance we can persuade him to move across the Atlantic and run for President?
Okay, so it would take a constitutional amendment, BFHD. It'd be worth it to get a decent President for once. In my lifetime, each one has been a few notches worse than the last... and I was born during the Nixon administration!
You are one of a very few in a forum crawling with OSS propagandists and knee-jerk M$ bashers.
I don't care for these any more than you, but I care even less for people who constantly complain about it even when it isn't happening. The fact of the matter is, the number of messages complaining about this are actually greater than the number of messages doing it. Thus, the people complaining are in fact far more annoying most of the time...
I got your point just fine, you seem to have missed mine. If you want to complain about some people's posts, reply to their posts at that time. Since you weren't doing that, just complaing in general, I would have to say I don't believe you when you say "no, I'm not trolling". Wait until someone actually does something to complain about before complaining, and then you won't be a troll...
A lot of people are under the mistaken impression that this is a useful security check. In fact, it means jack-diddly-squat, as (a) DNS is not a security protocol, so a positive result on this test means nothing, and (b) half the ISP's in the world can't get reverse-DNS set up correctly, so a negative result also means nothing.
If you have known incoming IP's, I believe adding them to/etc/hosts fixes the problem. Complaing to your ISP may help, but if your ISP's DNS admin has a clue, he'll probably point out that this is a really stupid test to be performed to begin with so he doesn't consider it a high priority to fix things on his end so it'll work, but he may get around to it eventually...
Which message are you replying to, or are you just trolling?
I see no double standard here (if you do, again, please point out which message). I always complain about sysadmins who don't install the latest security patches, regardless of OS. If it appears I complain about IIS sysadmins more than Unix sysadmins, it's only because I get that opportunity more often...
