    Hi,

    The DOE has guaranteed to monitor and control the radiation output of Yucca mountain for a million years. That's right, 1 million years - it's the furthest out the government has planned anything.

    We have spent $2 billion to study the geology of Yucca mountain, and there is no concern of someone getting hurt by any catastrophic event.

    This is paid for, in part, by selling electricity to the tax payer from DOE's reactors.

Later on, they determined the device was harmless, and (to me) it appears that she was just dumb, but there was no intent. To have a hoax device, you must intend for it to be a hoax.

    It's a tricky situation. She was headed to MIT's career day, and dropped by the airport to pick up her boyfriend. For career day, she made a little LED nametag with a 5 point star which lit up.

    Get it? It's a light-up star on her nametag, and her name is "Star".

    It sounds like a ticket person outside asked her what it was and she ignored/didn't notice them. Don't know what the silly putty was about. The ticket person did exactly what they were supposed to do when something is suspicious and called the police. The police responded exactly to protocol.

    It sounds like the police is running on a little too much testosterone when he said "she's lucky she is in a cell, not a morgue"; that's the sort of thing which exacerbates a media situation. He should have shut up an let a PR person handle it. I'm sure they would have shot her if she started running or something, but she had no reason to.

    The police responded according to protocol. The girl did a thoughtless thing (should have answered the ticket lady's question about what it was). In the name of good security, you sometimes have false positives. If there was a mistake made and it so obviously wasn't intentional, the police should search you, question you, and send you away with the crap thoroughly scared out of you.

    My frustration here is when the police take a simple, thoughtless mistake (she was just on her way to career day!) on some poor college student's part and blow it up into an international media incident, make it sound scary ("We almost shot her! blah blah blah"), and charge her with a crime (hoax bomb device) that obviously is false.

    The definition of hoax is "humorous or malicious deception" according to my dictionary. Unless the bit about the Play-Doh ends up being a significant part of the story, you *really* have to stretch things to make her actions sound malicious.

  13. Re:Why is it stupid? on Fork the Linux Kernel? · · Score: 1

    Forking the Kernel in desktop and server forks will mean that each specific kernel is optimized for such tasks and that the distribution makers have just a subset of the huge kernel to care about when creating their distributions.
    Actually, I have a better idea! Let's make it so, at runtime, folks can unload or load tasks - heck, let's call them modules - from the kernel. Even better yet, if there was only a way to control various tunings and constants in the kernel while the computer is turned on!

    Sarcasm aside, it's the job of the distributors to tune the kernel for their customers. Redhat tunes their kernels for high performance servers. Ubuntu probably tunes their kernels for desktops. If there was some large-scale concerted effort where desktop performance was sacrificed for server performance and such tunings *couldn't be adjusted* at runtime, I might be concerned. I just don't see it happening now.

    I wonder if their thinking is that, since X% of the Linux developers (say 40 devs) are server-oriented (because that's what they are paid to do), that if a fork is performed, 40 highly skilled, unpaid kernel devs will magically appear for the desktop. Sure, one or two people might be able to do this, but there would be nowhere near the backing. Canonical might contribute a bit, but Redhat/IBM/Novell wouldn't.

    Unless lots of money appears for Linux on the desktop, a desktop fork of the kernel is DOA.

The front and back ends are necessarily extremely complicated, but you can rip the entire front end and compile your code to GIMPLE, or whatever their SSA form is called. There also have been several different languages (Java, C, C++, Ada, Obj-C) that are production frontends to GCC's backend.

    I do know that I wrote an intermediate analyzer for a semester-length class, along with another grad student. In fact, the prof suggested we use GCC because several others have done the exact same thing, going back many years. It's not easy, but it's possible.

    These tests *did* factor performance into this (well, that's what the tester says. Intel is contesting this claim. You decided who you believe). In fact, those tests draw the same conclusions as folks I know who recently bought Opteron servers.

    The Intel chips have great performance per watt *as a chip*. Perhaps even better than AMD does; I've never measured a chip's power usage.

    The Intel servers, on the other hand, have worse performance per watt *as a fully loaded server*. Unless you're running the chip without a server, you generally should care about the power draw from the outlet - like these tests did.

    The Intel servers seem to have the edge in performance per watt when the server is going nearly unused. However, in my area, usually the CPU is pegged 24/7 (unlike, say, a webserver).

    Netlib is great for low level algorithms written by experts, but is the pits for usability. For example, a matrix-vector multiply in BLAS is called DGEMV (not exactly obvious to beginners), and has this calling sequence:

    DGEMV(TRANS,M,N,ALPHA,A,LDA,X,INCX,BETA,Y,INCY)

    Oh, and if you want to parallelize this, you have to use ScaLAPACK which is even more horrible to use.

    On the other hand, PETSc's C interface looks like this:

    PetscErrorCode MatMult(Mat mat,Vec x,Vec y)

    You pass it a matrix object, an input vector, and an output vector. If you want it parallelized, you start it up with mpirun on your cluster/SMP/NUMA/BlueGene machine. The same code is portable to all.

    And yes, there are python bindings which makes the above calling sequence even more stupidly easy. They give you a MATLAB-like syntax with the ability to scale from 1 - 5000 cores.

It may also be unreasonable for a local government, community association or landlord to require a viewer to incur additional costs associated with installation. Things to consider in determining the reasonableness of any costs imposed include: (1) the cost of the equipment and services, and (2) whether there are similar requirements for comparable objects, such as air conditioning units or trash receptacles. For example, restrictions cannot require that expensive landscaping screen relatively unobtrusive DBS antennas. A requirement to paint an antenna so that it blends into the background against which it is mounted would likely be acceptable, provided it will not interfere with reception or impose unreasonable costs.
