  1. That's processors have caches (lots of) on High Performance DDR2 Memory Breaks 1.25GHz · · Score: 2, Insightful

    and yeah, BFCs (big, fast caches) are far more important than fast main memory for the majority of applications. Nevertheless, these fast memories sell really well on the enthusiast market, where most people don't really know what a cache really is.

  2. Tell that ... on Dow Jones Plunge Fueled by Overwhelmed Computers · · Score: 1

    To super-duper, high energy alpha particle and gamma rays. Why do you think that ECC is so widespread? Not only for RAM - most processors these days have their caches ECC-ed as well.

  3. All these CS graduates should get jobs? on How to Keep America Competitive · · Score: 1

    Good lord ... There's so many dumbasses that graduate at tier 1/tier 2 universities.

  4. Re:Care to show a proof? on AACS Device Key Found · · Score: 1

    Well, the problem with the "plaintext" (i.e., photons traveling to your retina) is that recording it at that stage degrades its quality significantly (at least with today's recording technology). It's a bit better with sound, but some audiophiles would complain about that as well.

  5. Care to show a proof? on AACS Device Key Found · · Score: 1

    I mean, a formal proof. You're making a pretty broad statement, after all. The fact that some DRMs were cracked doesn't necessarily mean that all of them are inherently crackable.

  6. what about memory encryption? on AACS Device Key Found · · Score: 1

    The CPU can encrypt memory transactions on the bus. There are several research proposals that address this issue, btw (e.g. Xom). My point - they can continue the arms race as well.

  7. well, not quite on Consumers Unlikely To Pay $500 for iPhone · · Score: 1

    All definitions of inflation that I've seen are based on prices of commodities, services, real estate, and not on relationship to other currencies. You're actually saying "Things haven't gotten much more expensive here but they are cheaper in some other countries". It's quite easy to interpret that as "Those currencies have appreciated".

  8. Inflation depends on how you measure it on Consumers Unlikely To Pay $500 for iPhone · · Score: 4, Informative

    Inflation has destroyed the US dollar (down 50% in 5 years), so prices double of what we paid 5 years ago can be considered "par" with the fall in value of the dollar.

    If you consider inflation to be the value of precious metals such as gold, then sure, you can get to absurd values such as 50% (mind you, there's no such thing as absolute reference value). OTOH, if you consider consumer price indexes, it's much lower - between 5 and 10%.

  9. Curious on Quantum Computer Demoed, Plays Sudoku · · Score: 4, Interesting

    I'm actually curious - for how long do the 16 qubits stay coherent? You can only do quantum computations while the qubits remain coherent. Furthermore, IIRC coherence times where (at best) in the range of a few microseconds.

  10. Using a pirated copy ... on One In Five Windows Installs Is Non-Genuine · · Score: 1
    is actually a pretty bad deal. Quite often people tell me "hey, I've got this issue with my computer, I think the hardware is dying". To that I reply - "well, re-install windoze XP, but use a legitimate version this time around". 80% of the responses are - "wow, how did you know?".

    Anyway, if you don't want to give money to Microsoft, simply don't use their products.

  11. The problem with high clock is not just heat ... on Pentium 4 631 Overclocked to 8 GHz · · Score: 5, Informative

    It's also how fast your circuits can switch, and how fast the signal can travel on the wires. The execution core of a Pentium 4 also happens to be double-pumped (i.e., it performs operations on both edges of the clock signal). Essentially, those ALUs would be switching at 16GHz ... I, personally, take this with a grain of salt.

  12. what about Candu? on NMR Shows That Nuclear Storage Degrades · · Score: 1

    if I understand correctly, conventional waste works quite well as Candu fuel, with little processing.

  13. The other issue ... on First Cellphone Use On Airplane Given OK · · Score: 1

    is EM interference. Cellphones (especially the GSM ones) tend to be quite noisy. Don't believe me? Make a call near a radio.

  14. Compare to the previous-gen XBOX on Wii Launches, Sells Out Peacefully · · Score: 0, Troll
    CPU 733 MHz Intel Mobile Celeron
    GPU 233 MHz NVIDIA NV2A
    Memory 64MB

    Oh well, I've got a few karma points to burn...

  15. There's a problem though on "Dilbert" Creator Gets Voice Back · · Score: 2, Insightful
    The actual relationship between AI neural networks and the brain is really weak. From the wiki article:

    Neural networks, as used in artificial intelligence, have traditionally been viewed as simplified models of neural processing in the brain, even though the relation between this model and brain biological architecture is very much debated.

  16. My solution ... on ChatterBlocker — Block Distracting Speech at Work · · Score: 1

    "White noise", by Carl Friedrich Gauss. Best music ever!

  17. I patented prior art! on Cisco Patents the Triple Play · · Score: 2, Funny

    So quick, gimme 10$

    Most of us don't suffer from Triskaidekaphobia

  19. Not "owning" the IP? on Open Source Venture Capitalist Answers Your Questions · · Score: 2, Insightful

    If I understand correctly companies like MySQL own their IP, they just license it under GPL ... Seems like a strange omission from a seasoned VC.

  20. How about ... on A Lot of Money for Playing Games · · Score: 2, Interesting

    Game tester. It's not really that fun (playing same games repeatedly until they're balanced/stable enough), but he's got the skills.

  21. What next, tax the bible? on Indian ISPs Taxed for Generating "Light Energy" · · Score: 1

    After all ... "let there be light".

  22. he mentioned RS232 on How a Wiring Rack Should Look · · Score: 4, Informative

    I honestly don't think that it was much of a problem for RS232 communication (i.e. high-voltage, relatively low frequency).

  23. I don't get it on Ionic Cooling For Your Computer · · Score: 4, Insightful

    Would someone enlighten me? What is the principle behind ionic cooling? The article shows how to build it, but not why it works :).

  24. Re:Derived work on Alleged GPL Violation Spurs Accusations, Lawsuit · · Score: 1
    I'd agree with you, if the software already had that socket interface in place, as a means of communicating with other programs. But, it seems that in this case it didn't originally have it. Basically, he modified the software, and replaced procedure calls with remote procedure calls ... So, I stick to my opinion that it is derived work.

    Yes, the definition is particularly vague, that's one thing they're addressing in GPL v3.

  25. Derived work on Alleged GPL Violation Spurs Accusations, Lawsuit · · Score: 4, Informative
    The GPL FAQ is just a FAQ. The legally-binding license (v2) only says "Derived Work". Now, Jin is a chess client; what happened here is that Rabinovitch extended the client to do voice chat. Doesn't matter that he wrote it in a different language and that he interfaced it with sockets, this, to me, is a clear case of "Derived Work" (IANAL though).

    The whole socket thing is meant for something else. Staying in the realm of chess, there's a generic chess protocol that is used to interface engines with clients. If you have a server and a client communicating over such a generic protocol, and one of them is distributed under GPL, it doesn't mean that the other one also has to be GPL, because neither is a derived work of the other (again, IANAL).

    Finally, regarding EULA - GPL is not a EULA. He can distribute the binary client under a restrictive license, but he has to provide the sources under GPL. Rabinovitch seems to be in non-compliance here as well.
