As long as you keep your voltage below about 2V, you should be okay. Some have taken it up as high as 2.2V or so and not had problems, but I wouldn't condone that on any expensive chip.
However, what's the point of worrying about fried hardware? Those of us who overclock our systems to such degrees replace hardware every 6 months at least.
No, when it's cooler, you can increase the voltage without it crashing. The higher the voltage, the more performance you will be able to squeeze out of it, at the expense of heat. So you need something like this to dissipate that heat.
What? That's just stupid. Of course you're not going to actually run it below zero. However, more cooling = more voltage = more multiplier. Investing in an expensive cooling system lets you overclock more than one chip.
For instance, you spend $200 on your cooling system, save 150 on an equivalent CPU, then upgrade your CPU six months later and save another 150.
Perhaps they mean a four-dimensional donut, such that it's possible to travel forever in 3d space. Much like you can arrange 2d space into a 3d donut and create an infinite surface.
Nice, but I actually find the shares convenient at times. For instance, suppose I've taken my computer to my friend's house. I've got some mp3s he wants to play, but alas I have brought only my headphones. I could get up and go all the way over to my computer, but instead I can just open \\mycomputer\D$ and enter the password when it asks. No need to point out security implications.
Heh, yeah. Too bad all those are painfully slow. You CAN get dedicated RAM disks, but why, when there's disk cache? The current system is the best: mass, slow storage with fast caching. If you want a RAM disk, just throw as much RAM as you can into your box. Most of it will go to disk cache.
I wonder if games in recent times use memory mapped files instead of buffers and reading files into them? I imagine they don't. That's a shame really, as it is wasting a tremendous amount of memory.
No, it would still be pretty obvious with a reasonable disassembler which takes you to the area of password comparison. Hiding things in integer constants or whatever is really not going to make any difference at all. int i = 'fart' is still going to say 'traf' inside the executable.
OpenGL has a relatively small set of features out of the box compared to D3D. This is my point: in Direct3D there is one way to do many things which are vendor-specific extensions in OpenGL.
No, you are missing the point. In OpenGL if you want to do a matrix transform in hardware and get the result you need to push your modelview matrix, load it, do the operation, get the matrix back, and pop it. D3D provides means of doing this with a single non-kludge call.
Possibly. It's not an amazing feature since models are rarely one-sided.
Because it doesn't. Quake2 (1997) was using OpenGL extensions, possibly quake1. If Carmack used d3d (I shouldn't even say "if"...) there would be no need, as the functions would be available natively (although, probably a bit later.)
Okay, I didn't know that. Software OpenGL is painful in Windows regardless (even just GL_LINES.)

State machines are quite rare in APIs. I mean, usually you pass around a structure and set variables in it. Sure those variables change options, but it is always clear what those options are, because they are right there. In OpenGL they are accessed by functions. I understand this is almost the same thing but it feels unnatural to me.
nt
Well, even if the reason is less than kosher, the results are still there. Right now I can get DirectX 9 support, but how long before OpenGL 2.0? Chances are it will take a while.
I don't think it's changed much. You were probably just unfamiliar with COM. It can all be done in under 100 lines, it's just a few functions with very short names and very short parameter lists (how un-Microsoft.)
Direct3d's API works across all video platforms so long as the drivers are compliant. No extensions, so you write your code and it works on all cards. Nonsupported features are emulated in software.
Direct3d has slightly more functionality. Ie, can do matrix operations in video hardware and pass the results back, although this is likely slower than doing it yourself except in rare circumstances.
IIRC, the only thing OpenGL lets you do that Direct3d doesn't is dual-sided polys: you have a single triangle with a light on either side, and the two sides will be lit appropriately. I guess in d3d you would need to draw two tris which isn't really a big deal since one of them will be backface-culled out.
Direct3d is meant for what we have today instead of being the same set of commands which have been extended over and over again.
In windows, Direct3d's software renderer is pretty fast, but the OpenGL software renderer is painful. This is possibly intentional.
OpenGL has a much cleaner API: straightforward, short functions which scale nicely. For instance you can start drawing all your triangles individually, then move on to triangle strips, then display lists, then vertex arrays, etc, over time as your knowledge increases.
Direct3d makes this a little bit more painful. Usually involving filling complicated structures and the like.
OpenGL is very state-oriented. Personally I find this a bit strange. States are usually a bad thing, see any jef raskin rant.
Of course, opengl is portable whereas direct3d is mostly windows specific.
Hardware vendors are usually quick to support direct3d.
In windows, it is somewhat more painful to get an opengl context set up: need to create window, set pixel format, create gl context,... ends up being about 1000 lines with good error checking.
I'm sure there is more I'm not thinking of. These were just things off the top of my head. Personally I use opengl just out of preference for the command syntax.
36C? That sounds a bit low. Perhaps you have an A7V8X? Those are a bit notorious for reporting bad temperatures. If not, overclock that sucker till it bleeds!
Well, at least I am an uninformed idiot whose mailserver isn't an open relay.
Nor is mine.
As a satisfied user of SPEWS, I would like to see some proof. When you accused SPEWS of ignoring phone calls, you made a factual error: SPEWS can not be called, so they can't ignore phone calls.
No, I made a linguistic error. What proof would you like? What is there to prove? They are so shady that there are no records of anything. I could show you unanswered emails, but they would be too easily faked to be relevant.
May I remind you that I am not listed? Perhaps I am not as stupid as you think. For example I did not suggest booting clients on the first incident, I suggested suspending their connection until they fixed the problem.
So what? I am representing a colo facility with dozens of servers and thousands of addresses. Of all this, there are occasional errors. The fact that you suggest booting a client AT ALL due to a technical error goes to show how ignorant you are. If a client is intentionally spamming we give them the boot right away. If they are an open relay, even if due to incompetence, they fix it or we fix it. Suspending their account would be stupid. We would lose the client. Terminating their account would be stupider. You are what, 13? Shall I unplug their drop and send them an email stating "haha fag u should use m$ winblows cuz u dont kno how to configure ur server by the way i use linux"? No, we kindly inform them of the problem, like people over the age of 15 interested in making money and retaining good business relationships. Then the client brings in more servers or traffic or other clients, and I get to do really great things, like eat.
No, that is completely harmless. It would even been alright for you to power it up after noticing this problem without rebooting the box (although the OS would likely not detect it.)
I've tried doing IDE hotswap experiments with ancient hardware, and never fried any of it, but there were some arcs, so I'd reccomend against it on modern hardware.
Everything you list is pretty harmless. Well, except the drive dropping, although when they're off, the head employs a locking device.
Drives are meant to receive power and signal independently. You can even give it the 5V line before the 12V, or the other way around, it'll be fine. Just don't UNplug it while it's on, as that will likely crash your OS (but not damage the drive.) And you don't want to plug the signal cable in after it's powered up, unless it's SATA.
You can also safely power it up without a signal cable if you want to test noise or something.
Only if you have a lazy provider (like yours) which allows morons (like you) who repeatedly open their relay. If your provider would have acted promptly (suspending you the first time until you found someone qualified to operate as root; kicking your sorry ass the second time), the listing would not have grown to a/24.
You sir, are an Idiot. Not to mention entirely uninformed. There are no "spam reports". There is no/32s growing to a/24. They just bury the whole block. Not that they bother to check ARIN for the actual block boundaries.
As for an ISP booting clients for having an unintentional open relay for an hour, well, such a stupid idea isn't so surprising from an idividual as stupid as yourself. Go start an ISP, go try it. We get this shit almost every day. People screw up, they fix it, life goes on. Really though, thanks for the suggestion, I appreciate it. It's just that it was, you know, completely stupid. Keep trying though, you might make a good one some day.
The level of stupidity necessary to allow your sever to act as an open relay also, by definition, precludes being considered a "good" server.
Not quite. If qmail's control/rcpthosts file is missing, it behaves as expected, but acts as an open relay with no warnings whatsoever. (eyeroll) this has burned me a few times.
In one case, it got my block listed in SPEWS. Now, let me give a small rant about SPEWS. SPEWS has to be one of the biggest disservices on the entire Internet. They don't bother to only blacklist hosts that are known open relays. They don't bother to only blacklist blocks. Oh no. They just blacklist the/24. So if you are on a/26 or/28 (VERY common colo assignments) and your neighbor gets buried, you get it up the ass too. They are very difficult to get off of. They ignore email and telephone calls. These guys are far worse than the spammers they are supposedly trying to prevent, because they result in tremendous amounts of false positives and lost mail. Whenever one of my clients or neighbors gets a block buried, the phone rings off the hook for the next two weeks because random messages are getting thrown away by admins stupid enough to actually use spews as a blacklist.
Seriously, please boycott them. Use a heuristic spam detector like spamassassin which tags messages instead of throwing them away.
No, fellow poster. It doesn't make you cool. It is merely one's cry to be accepted by the rest of the slashdot community: I hate microsoft too, just watch how I misspell their name!
I recall Tycho of Penny Arcade fame mentioning his use of a mail client rule which abandons all messages containing the string "M$"...

That diner image gives me whack dejavu/nostalgia... what's the original? It appears to be a bit of a recurring theme.
That would involve getting up and going all the way over there. My anecdote was meant to be nonspecific.

A dozen per day?
My DSL connection with five IP addresses behind it receives about ten requests per hour per address. All firewalled of course.
My colocated server receives about twice this.
Not trying to show off my internet penis here, but rather, I think you've rather understated the severity of smb scans.
Easy, in the properties for your external network interface, simply uncheck "File and Printer Sharing for Microsoft Networks."
However, I don't think this is particularily amazing advice... only applicable to a box which happens to be acting as both a fileserver and a gateway.
If I had mod points, I'd Overrated the grandparent for exactly this reason.
