  1. Re:256 cores... pfft on Windows 7 To Be 256-Core Aware · · Score: 2, Informative

    256 cores means that it can be stored in a 16-byte flag. Coincidentally, most current implementations of x64 (not the very first Athlon64s, though) implement instructions for atomic 16-byte operations. It seems like MS thinks that the performance benefits of being able to store affinity and other status flags in this manner outweigh the downsides. By the way, I would say this is more to handle things like 32 cores of 8-way SMT, than 256 actual cores. MS can accept losing the niche of very large shared-memory systems, but not the midrange servers of tomorrow.

  2. Re:Isn't quantum effect the main problem now? on 100x Denser Chips Possible With Plasmonic Nanolithography · · Score: 1

    Semiconducting is always a matter of quantum effects. The doping needed to get the desired effects are going down to single atoms, which complicates things, and tunneling can certainly also be an issue, but it's not like these things would rely on the world being essentially Newtonian.

    Let's hope that the renewed Samba compatibility effort by MS means that this bug will be ported over.

  5. Re:C++ functional? on 6 Languages You Wish the Boss Let You Use · · Score: 1

    The STL library is part of the C++ standard. It is a crucial part of the language, forming many of the idioms in it. Just like malloc in C. In C and C++, you can at least imagine the language without its libraries (although RTTI, constructor calls for global variables and the matter of the entry point at all require some hefty bit of imagination to get it without libraries).

    For a language like Python, the distinction makes no sense. The syntax is filled with sugar resulting in function calls (on the interpreter side) that can be overloaded to some degree. C and C++ are no less versatile by the fact that much of the functionality expected is found in the standard libraries and can be excluded. They are less versatile due to the limited total functionality of those standard libraries.

  6. Re:Use them as CAPTCHA... on Optical Character Recognition Still Struggling With Handwriting · · Score: 1

    The other solution for pairs (which I think was also suggested by recaptcha) is to use two words. You are you told that you have to answer both right, but in fact at least one of them can be somewhat uncertain, and the system will accept your input if it matches for the already fixed image. The already certain set can start out as rather small and simple, but it will grow quickly, even for a small site. You can still require 4 or so identical answers (with no conflicting ones) to the same image for it to be added to the "safe" set.

  7. Re:Too variable, less reference on Optical Character Recognition Still Struggling With Handwriting · · Score: 1

    You are right, but on the other hand a really good scan might be able to indicate the order. Paper that was already wet will react slightly different to the next ink stroke, etc.

  8. Re:also my changes leading up to this moment... on Getting Paid To Abandon an Open Source Project? · · Score: 1

    I think the poster means that the copyright would be transferred to the company, i.e. the BSD remains, but they get full rights to his work, including the ability to relicense it (a right which is far less valuable for additions to a BSD codebase than a GPL one, but it's still worth something). Relicensing naturally doesn't affect licenses already given out.

  9. Re:Electric Gas Cans? on Plug-in Hybrids May Not Go Mainstream, Toyota Says · · Score: 1

    The European Prius has an EV button which will go electric-only when you drive below 45 km/h (roughly 30 mph). If you try to accelerate quickly, the gasoline will kick in anyway, but if you just push it mildly you will have a car that will keep going electric even in circumstances where the gasoline engine would normally kick in for quicker response. It also reverts to gasoline automatically when the battery goes low. Despite all this, it is definitely different from the normal driving mode. Great for garage parking, or when you want to sneak up on people, eh...

    Power draw will affect heat output. Of course, we can have a good design radiating heat out in a way that is no inconvenience to the user, but most systems will turn up their fans or get hot to the touch in inconvenient places.

    Then you haven't looked around too much. The PLoS journals are one thing, and several other journals are warming up to open access in different ways, some accepting immediate release at a (modest) cost for the authors. This all still involves peer review.

    Any time you see a program installing a vxd you realize it was written for Win9x and will only potentially load under the NTVDM 16-bit emulation layer, or not at all. Windows Me was the last Windows release loading any proper VXDs.

    Nope. Only twice a year if you are within the tropics, i.e. +/- 23Â 26' 22". For someone living at 60Â N, it's quite evident that we never have the sun in zenith, but we are also a far shot off from actually being north of the arctic circle.

  16. Re:Rudimentary on Prions Observed Jumping Species Barrier · · Score: 1

    Of course it randomly happens. Some individual was the source, huh? It's even likely that some individuals have a genetic propensity towards a mal-folded protein, but as soon as you have that, the prion can transfer to other individuals through ingestion. What all this means is that we should always expect a very low background frequency of cases. We are very far from the epidemic proportions once seen in the UK these days.

  17. Re:How will this effect atomic clocks? on Nuclear Decay May Vary With Earth-Sun Distance · · Score: 2, Informative

    What's used is the resonance frequency, not the decay rate. It is also the resonance related to electron transitions, not the nucleus. Naturally, the fine-structure constant will influence just about any physical process, though. (That's one of the reasons to prefer the neutrino explanation.)

    Well, the stated capacity of the battery slice is only about equal (85 watt hours or so) to the standard 9-cell battery, so it's not that heavy. And, yeah, to get 19 hours you use the SSD, keep the display dimmed, have no optical drive, and use integrated graphics.

    Hint: an interface is not defined by using the same trademark/consumer name for it. SCSI has switched connectors and signal modes so many times in that timespan it's not even funny (and, AFAIK, the logical interface is quite changed as well).

  25. Re:Ha! Yeah right. on Interview Update With Bjarne Stroustrup On C++0x · · Score: 1

    Well, one reason to find it funny is that function calls are expensive these days. Small operations encapsulated in libraries that are only available through linking can degrade performance, even if the implementation is superior. That's one reason to prefer inline assembly in C++. To top it off, introduce the specific implementations as template specializations, for example hand-unrolled loops for a few specific small sizes. That is simply not possible to do in C, or macro assembler, without introducing a maintenance mess.
