Brought to us by the same people that told us the big pipeline would solve all our problems and that RISC was a deadend, that bought up and squashed the ARM, that thought that no one would need more than 8 registers or 640K of memory and all the other crap Intel have spouted since it invented the 4004 and then proceeded to get everything else wrong.
Actually most of the design work came from HP's VLIW research team.
I also find it disheartening that you are trying to prove your case by defaming Intel, which is the weakest form of argument (pathos) according to Socrates.
You're saying the compiler has knowledge of registers, and what branch will be taken? Further you're saying the compiler has knowledge of the *current* memory structure? Latency of a particular memory fetch/store (whether the data is in L1/L2/L3/L4/L5 memory?). When DRAM refresh is going to hit (if ever). Or that an interrupt may come in randomly.
All this info is VERY useful for the processor to reorder its instructions to avoid a pipeline stall. But of course, you'd say the compiler knew all this detail ahead of time - right?;)
Having more data at compile time does not preclude having the same branch prediction and memory access data in hardware, as you imply. Itanium still has the ability to do branch prediction and handle memory latency the same as any modern processor. Why don't you read the documentation and get back to me?
And i'd really prefer to avoid optimized recompiles during VM page swaps. They take long enough as is. And really, on a decent system - you shouldn't be paging!
The reason you do this during a page swap is because that is when the processor would normally be stalled/idle waiting for data or instructions anyway. If implemented properly, this requires no extra cycles to perform. Every system page swaps, which is why TLB's (translation lookaside buffers) exist...to translate between virtual memory addresses and local memory addresses.
20 - 8 means a slower clock???

With an 8 stage pipeline, as opposed to the 20 stage pipeline in the P4, clock frequencies are obviously not as high (~1 GHz).
What??? That's totally false, not to mention counter-intuitive. The whole reason for the shorter pipeline is to increase throughput. Think of Henry Ford and the classic assembly line. If you have stages that involve scheduling instructions to be fed into different (parallel) pipelines, as opposed to DIRECTLY COPYING instructions from cache into the appropriate pipeline, which do you think should be faster?
Apparently you're not familiar with VLIW processor design. It's not "throwing it off" to the software guys because it's too difficult to implement. It is dramatically reducing the complexity of the pipeline, thereby increasing throughput by orders of magnitude (see CISC vs. RISC).
And the compiler has far *more* information than the runtime hardware has. The scheduling hardware is only capable of looking a few instructions at a time to decide how to enhance ILP, whereas the compiler by its very nature has access to the entire program at once, and can perform optimizations not possible in hardware.
This is further enhanced by a development cycle that includes profiling. As you use the program during development, the compiler can use the same profiling information that is used to "manually" optimize code to perform its own optimizations. With an advanced OS, this become extremely powerful, as some of the registers on the processor actually keep track of profile data at runtime. Then, during page swaps to/from virtual memory, the processor has the opportunity to dynamically optimize and recompile the code.
It seems like Dr. Farid's research would have wide application in detecting and "battling" related technologies like digital watermarking in sounds and images. I wonder if the media companies will try to use the DMCA to bully him out of his research, as we've seen in similar cases.
When can we expect to see new modes of play? Counter-strike is somewhat of a new light on the horizon, but it is not a big
step away from the mainstream of the genre. Black and White is more of a truly new idea. Can we hope for more games that
demand entirely different modes of interaction than firing big guns at everything that moves? Can we hope for non-violent
but fun games going online? Can we hope for games that don't even have a hard-core competitive profile, but more of a
community feeling to them? Can we hope for collaborative 3D games that appeal to a broader adult audience, or to younger
children? Would anyone want them?
Apparently he has never heard of Everquest, Asheron's Call, Anarchy Online, or the plethora of other online RPG's. In addition to the egregious errors pointed out by Mr. Carmack above, I just don't think this guy did any research at all.
I even sent email to Macromedia asking if their site was down, but they were as confused as I was in their reply. They said they were not showing any problems, but that others had reported the same issues.
Let me get this straight. You were able to receive email from them, but couldn't get on the website? I thought the point of the RBL was to block spam (which they apparently didn't), not web access(which they did). Looks like they fucked up twofold.
The British have a soft spot for eccentrics and kooks and they'll let the "Royal Family" have their fun as long as they're not doing any harm.
What??? He said it's "...just not good business practice for HavenCo...". That doesn't have anything to do with the British or US government, but profitability. It's pretty hard to make money by giving away free services to a bunch of hungry leeches, as evidenced by all the failed and failing dotcoms based on that business model.
Didn't you take any humanities courses while you were in school?
I took a year "off" and spent one academic year taking almost no engineering courses, and instead focused on humanities/economics/etc. That was by far my easiest year in college. I spent much more time drinking and carousing, and much less time studying, and was still able to effortlessly pull down straight A's.
By the way, I would recommend the same to any current/aspiring engineering majors (not just EE). It gave me a much broader perspective than I would have come out of school with otherwise.
I am currently engaged to a Japanese woman, and am particularly interested in this issue. I did some research on both the INS and State Department websites, and I can't find any evidence to support your statement that being married outside the US changes the application (or approval) process.
From what I can tell, the same forms have to be filled out and submitted to the same agencies in either case. Could you please provide more detail on which parts of this process are different? I would also really appreciate any additional advice.
It's quite possible that NBC will not make ANY money off of the Olympic broadcasts this time around.
Actually, NBC turned a profit (around $200 million I think) before the Olympics even started. They paid around $700 to the IOC for the rights to broadcast the games, then turned around and promptly sold close to $1 billion in advertising. They claim their expenses (equipment, labor, etc.) run around $100 million.
Of course, I don't expect the same strategy will work so well next time, what with the dismal ratings and all...
It was created at MIT around 1990, or at least the document about it has Feb. 1990 as its first revision date.
It's an instant messaging system, and as such, has some clients (some X clients, some tty, etc.), a distributed network, and servers which keep track of users, messages, and other stuff. Users can/could "subscribe" to certain classes of messages, which in effect causes the server to apply different filters to the messages that get percolated over the network to each user.
Try the above URL for some documentation, here's more of the old docs (postscript format).
I can't really help you with contact information, but I'm sure there are a couple emails listed in the documentation somewhere.
This article has little to do with "security through obscurity."
So far as I can tell, Ranum didn't say disclosing security holes is a problem. He said disclosing the hole, and along with it providing tools to exploit that hole is the problem that breeds script kiddies.
Do people even read the article before posting it? It seems the submitter was attempting to reiterate the title from the linked article, but failed to see how the new title dramatically changed the meaning.
I would like to add to this statement. As an independent musician, I, too would love to get paid. Occasionally, I do get paid, but I would do it anyway. Many of my friends actually manage to make a living as musicians, but all of them started out doing other jobs as a means of paying the rent, and did music in their free time.
Exactly how much do people need to get paid for their art? Do you really need hundreds of millions of dollars to continue being creative?
What about people like Britney Spears? She doesn't write, choreograph, or in any other way create her own music or performances. Basically, she is a glorified robot that performs instructions other people have written, and those programmers, so to speak, don't get paid nearly as much for their art as the robot. If you like Britney's songs, you should really be writing a check to the people that actually wrote the damn thing, because they sure as shit don't make a percentage.
Ok, so suppose under the new law the police do a search (without prior notification) which turns up drugs, and the guy goes to jail for a while. The first thing his lawyer is going to do is appeal on the grounds that the search was illegal, and this law will eventually get shot down as unconstitutional the first time it is actually tested.
This works for the static parts of the OS, but not for any user directories or/tmp. Remember that on the system in question users could log in and use shell commands, save files, etc.
Granted, this should prevent any rootkits from finding their way onto the system, but it's not an end-all beat-all, and a malicious cracker could still wipe out all the user directories (as did the guy in this story).
When I was living in Japan, I solved this problem by putting my phone on "vibrate" mode. My phone also came with a keychain attachment that also vibrated. Whenever I got a call, I got an exciting jolt (I kept it in my front pocket) and could discretely leave the room to answer the phone, with none the wiser.
I've never owned a cell phone in the US, but I have always assumed they US cell phones have this feature as well. Is this not the case, or are people just rude?
That's funny. Most (99.99%) anime otaku I run across don't speak Japanese well enough to tell if the script's been butchered or not.
That being said, I definitely wouldn't buy it if the Japanese track wasn't there. Actually, I'm put off by having English subtitles. I found that I have a tendency to just read the subtitles rather than listen to what is being said, which is a serious crutch.
Anyway, I have VHS versions of all the Ghibli stuff in Japanese, no subtitles if anyone's interested. Unfortunately I don't watch other anime, but I like MIYAZAKI's work.
Both parties still have to agree and understand the format and structure of the data before it becomes useful, so that's definitely not a progression over any existing technology.
Isn't that what schema are for? Or perhaps you didn't get to that in your vast XML programming experience yet.

Couldn't they use something like that in a catalytic converter for a car?

Hey, idiot. Did you look at the site?
Rusty has taken it *down* as in, kuro5hin is now just a single page that says they're tired of dealing with the problems, and they quit.
