Slashback: HETE, HP, Regression

Slashback with more on cheap satellites, the relative speeds of threads under Linux and two strains of Windows, a skeptical response to the idea that crowds of people are retreating to dial-up access, and some tantalizing hints at products killed along with the HP calculator division. Lies, Damn Lies, Statistics, Benchmarks, Etc. Writing with a followup to the Slashdot post titled, "Who Has Faster Pipes? Linux, Win2000, WinXP Compared" Splinton had this to say: "In this article, Ed Bradford compares semaphores, mutexes and window's critical sections. Pthreads look good, but Win2Ks critical sections are twice as fast again!"

The computing equivalent of Area 51? A short while back HP closed its calculator division. Many have thought HP's calculator department was unprofitable. This was not the case. Many have thought they had no innovation. This was not the case. Turns out that management had 4% workforce to kill and they were part of the cut.

This article explains more. It turns out they had designed several Linux based PDA's ready to produce that were killed by management. Sounds interesting? Go check it out.

The biggest expense was the 12 gross of Estes D engines ... Satellite Designer writes: "The topic of low cost satellites having been mooted here recently, I though I'd alert readers to another such project. The HETE-2 satellite recently located a cosmic gamma-ray burst precisely enough that (with a lot of help from friends) an afterglow was detected, identifying its source. HETE-2 cost $26 million, only 1/3 of what a 'small' scientific satellite normally costs.

A lot of commercial 'off the shelf' technology went into HETE. Nothing from Radio Shack, but there are quite a few parts from Digi-Key onboard. You can't save money by using cheap parts (but you *can* save money by using easily obtainable parts), and you can't achieve reliability by using expensive parts (but you *can* help reliability by using the parts best suited for your application). The radical thing about HETE's parts selection was that it considered parts in the application context (as one would do in a normal engineering process), rather than restricting selection to a QPL assembled to meet irrelevant requirements.

The real trick to keeping costs down is to do the job with as small a team as possible in the minimum time possible. Rather than employing a large team of specialists, HETE's scientific investigators did much of the engineering and technical work. A small, carefully selected engineering team filled in the knowledge gaps."

Quitting isn't easy, and why bother? dmarsh writes: "This new article from C|Net seems to be a total contradiction to last week's "Dump Broadband, Dig Out Your Modem!" thread's article. I guess the important difference being that this one is backed up by an actual survey by the National Cable and Telecommunications Association."

Goes to show, in a large group of people you can probably find at least some who fit nearly any premise. As always, question the source ;)

    The Cars - Magic

    Summer turns me upside down
    Summer summer summer
    It's like a merry-go-round
    I see you under the midnight
    All shackles and bows

    High shoes with the cleats a-clickin'
    a tempermental glow

    How far will you take it
    Well no one knows
    Don't let me go
    I got a hold on you tonight

    CHORUS
    Oh oh it's magic
    When I'm with you
    Oh oh it's magic
    You know it's true
    Got a hold on you

    Twisted under sideways down
    I know you're getting twisted
    And you can't calm down
    I see you under the midnight
    Love darts in your eyes
    How far can you take it
    Till you realize
    There's magic in your eyes
    CHORUS
