The GPL is not an end user license, the GPL is a redistribution license. I can change whatever I want in a GPL'd program and just like OSX there is nothing wrong, immoral, or otherwise illegal if I decide I want to change it to install it on a toaster or if I want to print it out onto a ream of fanfold and set it on fire.
I'm still not sure I follow your train of thought, doesn't seem unethical to me to buy software and do whatever I want with it in so far as I don't redistribute copies of it. If I go to a fancy restaurant and I buy a 100 dollar steak the situation dictates that it would be obscene for me to slather it with A1 steak sauce, but I'll be damned if it isn't my right to do exactly that.
Against the EULA does not even remotely mean illegal. And the EULA has yet to be tested in a civil court, could be that the EULA isn't even enforceable.
If the crack is a breach of the license then I suspect the license is wholly unenforceable, since the first sale principle says you can basically do whatever you want with what you own. Since you own the system you are installing the game onto you can freely flip whatever bits you want in whichever way you find most pleasing with whatever intent you wish. Likewise I'm free to buy a music cd and scratch the fuck out of the disc to make a track I don't like unplayable; in the same vein I can remove the portion of the software I don't like from my system and since it is not my intention to redistribute my licensed copy of the software it would seem quite a legal stretch to say that the publisher has any right to dictate how much of the original code I am allowed to run.
You can always flip the whole thing on it's ear and use the legal precedent of the "Hot Coffee" fiasco to claim that the ability to play the game without the DRM intact was the intent of the publisher since they made no effort to prevent unknown third parties from distributing a patch which allowed the software to run in it's modified form. The ability to play without the DRM inherit in the original software and then disabled intentionally in order to satisfy requirements prior to distribution. Thus patching the software to re-enable this feature is really the fault of the publisher.
I've heard before of not reading the article, but this is ridiculous, it says right in the abstract that they are using 70kg of the stuff. Prices online seem the range from about 500-1000 USD per gallon, usually in 3 gallon minimum quantities.
Check out my other comments on this topic, it's available in 3 gallon quantities for about 2500 bucks. I've heard of gallon jugs going for 500 bucks in the past, I believe that is what the octools guys paid when they were doing their extreme celeron overclocking back in ~2000.
An interesting thought, however as they are advising that the case could be used with standard off the shelf ATX computer components it seems highly unlikely that any sort of fluid dynamic or thermal analysis is going to be relevant across the wide spectrum of components that could be used in it. I'm thinking that the 10k USD worth of flourinert was their major cost incurred and the rest was spent on tacky LED lighting and heat forming that giant ugly acrylic case. The 100k USD r&d cost is probably marketing included so that people with more cash than common sense would know that this is excessive enough to bother purchasing. I expect that several of them will have been ordered and shipped to Dubai by the end of the year.
I'm not sure where you got the idea I was suggesting a different immersion liquid. If you checkout the rest of the comments on this story you'll see that I discuss fluorinert at least 3-4 times. I'm merely suggesting that wasting ~10k USD on coolant and then building a giant gaudy waterfall enclosure isn't exactly how I'd go about doing a project like this. A much smaller volume of liquid in a much smaller container with radiator/fan cooling could be assembled for about 2-3% of the cost they've incurred. Likewise a conventional closed loop cooling system that isn't fully immersing the system could be built for only a few hundred dollars and effectively cool all the components nearly as well and certainly be more cost effective. If you wanted performance you could build a whole cluster of either of the systems I've described for the cost that this article is advising.
Actually that isn't too strange of an idea. Flourinert, the coolant used, actually can hold a significant amount of dissolved oxygen and has been used in lab experiments where rats and other animals were kept fully submerged and breathing the liquid for a non-trivial period of time. So, I'd go with a larger tank and a small cadre of laser equipped, liquid cooled, attack tigers...
Flourinert is readily available from 3M in a variety of different compositions. It is the only exotic portion of this type of project and it's cost is the main reason why we don't see more full immersion cooling. I don't know about the rest of Slashdot, but I'd prefer not to spend several hundred dollars per gallon on cooling liquid in exchange for saving myself a little hassle removing cooling blocks from a [more] traditional closed loop contained coolant system. Not a whole lot to be gained from going to full immersion. Also, IIRC, California recently added Flourinert to it's list of potentially cancer causing chemicals, which IMHO makes it less than ideal for a warm LED lit water fall in your living room or office...
I agree with you, this looks like standard off the shelf gear stuck in cooling fluid from an existing immersion cooled computer all stuffed into a gaudy lexan case. I could easily build this in a weekend with a few hundred dollars worth of lexan from tap plastics.
Thanks for the link, but the single page on bluetooth there has basically no information, is only 2 days old, and references a development project which AFAICT hasn't even managed to develop themselves a web site to detail their travails. Actually the page even leads me to believe these people haven't spent too much time actually looking at the iphone's existing native bluetooth stack, since the mention the want/need to code a program to talk to the chipset over the driver's provided serial interface; neglecting to notice that apple actually includes a program, bluetool, which appears to do exactly that although it doesn't appear to have any documentation available. Anyhow, I'd characterize the third party bluetooth development for the iphone as a speculation and hopeful thinking at this point since there is little evidence of anyone actually making any headway.
Any links or info about these groups? I've recently been hacking around on my iphone and I've found virtually no reference anywhere to any active work towards enabling additional profiles or even documentation on the phone's existing tools for working with the 2 known supported profiles.
An interesting observation, which also points out something that I noticed in the review text. He says that all the scripts in the book are "POSIX" compliant, but AFAICT bash extends the POSIX standard bourne shell "/bin/sh" with a bunch of features which are not part of the posix standard. Calling bash from a "sh" symlink starts bash in POSIX compliance mode wherein it acts exactly like a standard bourne shell. It seems if the book has strictly POSIX friendly scripts that it isn't really a bash book so much as it is a bourne shell book.
Thanks for this, I have repeated this comment hundreds of times to various people setting up their networks and yet they still seem to think that setting the essid as "hidden" is providing some small extra security, when in fact it only obscures your network for legitimate users, since anyone sniffing for a networks will see it regardless of whether you have it set to broadcast or not.
The technical difficulty in providing a hidden and deniable filesystem is one seriously tough nut to crack. However providing full disk encryption is much simpler. I would agree that truecrypt has burned a little bit of their reputation, but I would hardly make the leap to not trusting their encryption technology since AFAICT it works well, is open source, has been subject to critical peer review AND has yet to have any cryptographic or implementation flaws found in it.
Did you even read what you linked? Schneier isn't sayign the encryption is weak, just that the "plausible deniability" of TC's hidden volumes is questionable.
Any admin, such as myself, whom works for a large ISP can look at your spam assassin header there and see a big reason why we can't and generally don't use your solution for filtering.
The majority of your spam ranking scores depend on some third party real time blacklisting services. My mail servers pass about a quarter of a billion mails daily, we end up on these blacklists quite frequently from ass hats whom manage the variety of 3rd party blacklists regularly accept falsified headers as proof of origin and they accept heuristic results from filtering appliances (I'm looking right at you barracuda) which can't tell the difference between high volume non-spam forwards and real spam. If you weight your spam filter to use that much blacklist input then there is a strong possibility that you are black holing tons of mail from large ISPs and/or causing all sorts of upstream queuing problems and delivery delays for users at your domain. Hopefully your servers only tag up the headers and don't actively do reputation blocking or any other such non-sense... Let your users make the final decision.
Graphics/Video
PS3 has a powerful graphic processing unit with high speed host connection. The GPU is connected to both HDMI and AV multi interface. Although the GPU is connected directly to CBE, no direct access by guest OSes to the GPU is allowed currently. Video mode/format setting is also the role of AV setting driver. PS3 Linux fb driver calls AV setting driver to setup video modes.
Currently X server uses virtual frame buffer to render its image. No hardware acceleration is supported under Linux. See the description above section.
Linux on the PlayStation 3 allows for a huge range of homebrew programs to be developed and is entirely and completely sanctioned by Sony. Although the Cell's performance is more than enough to handle most media requirements or render complex 3D graphics, it does lack the teraflops performance of a contemporary GPU's texture fetching hardware. For this reason many complex games aren't possible on the PlayStation 3 through Linux as access to hardware acceleration in the RSX is restricted by a hypervisor.
I'm not a game programmer, but it sure seems to me like having good hardware acceleration is going to make the difference between having to split your main general processing power between game logic and graphics rendering OR having 100% of each to handle the task that it is best suited for. So unless you have some justification for saying that I'm "pulling things from my ass" it seems like your statement doesn't really hold water to the generally available info. I've heard that some hacks are showing some limited success in gaining DMA control over the GPU hardware, but nothing is solid and the method by which access is gained is actively being patched out by Sony in an effort to control the channels by which AAA quality games can get onto their hardware.
Unless something has changed dramatically the "native linux" on PS3 is really running virtualized on top of Sony's own hypervisor which prevent direct access of the graphic acceleration hardware. In a practical sense that means that anything you "home brew" to run on linux on a ps3 is going to be hamstrung by it's lack of direct hardware access and won't stand a chance of being performance competitive with REAL native ps3 applications.
You point out that they were not applying the moderating guidelines and they respond by failing to apply them some more, without ever explaining why they disagree with you because they probably realize they would not have a leg to stand on.
I agree with the essence of what you are saying, but must point out that Slashdot's moderation system does not allow one to both comment an article AND moderate in the same comments section without nullifying their moderations. Thusly it a person who issues a dissenting moderation cannot possibly also explain the reasons for their moderation. Slightly broken system IMHO, but better than many other web forums which I frequent.

Seems to me like cracking your legally purchased/licensed copy of the game is legal.

Heh, looks like my recollection on the pricing is a bit off: 250ml for 555.35USD at one retailer and 3Gal for 2,450USD from another.
