  1. pedagogical journaling on Ex-Britannica Editor Reviews Wikipedia · · Score: 1

    this is about the author's statements regarding the practice of "journaling" in schools: i feel sorry if any students out there receive no further feedback than the grade based on the amount they write in their journals. my wife is a high school english teacher, and i must say, she spends hours reading each journal in detail and writes pages of feedback as well as meeting with each student to discuss the ideas which pertain to literature or language. that's the idea behind it, and she (for one) practices what she preaches.

  2. unflappable on 2004 Inductees to the Robot Hall of Fame · · Score: 1
    they called C3PO "unflappable"!!

    heck, R2D2 was unflappable... C3PO was completely flappable!! that was the point!

  3. Re:Saving energy... on How Wireless Meshing Could Save Energy · · Score: 1
    radio stations do get alot weaker as you drive away. your radio has an automatic gain control that compensates until you just get too far out of range.


    you do get a charge from a long piece of metal. radio waves are high enough frequency that the energy mostly travels on the surface instead of through your body. look up Nikola Telsa (already mentioned above) and find out how he often stunned audiences by holding a phosphorescent bulb and lighting it with the radio frequency current running along his skin. you can do it yourself by holding a flourescent tube while standing under high voltage power lines. there are radio frequency harmonics of 60Hz (or 50Hz) being emitted that can be strong enough. too much RF current, and you'll still get fried from burns, though.

  4. Re:I, for one... on How Wireless Meshing Could Save Energy · · Score: 1
    i'm curious... if a mesh network would increase efficiency at your installation dramatically, wouldn't a wire-based network be justified already? does the wireless scheme provide so much a better fit to the problem that it would be justified whereas a wire network would not?

    keep in mind a wireless mesh system may require it's own optimization and tuning to function in an industrial invironment...

  5. Re:Nice to see them so honest on SpaceShipOne Flight Not as Perfect as it Seemed · · Score: 1
    my impression from the article is that the loss of control as the craft left the atmosphere is probably a system problem, like the computer did not signal the attitude control jets to fire at first.

    also, i think they said that the deformed panel actually isn't required. if that's what the bang was, hopefully they can just strengthen it or eliminate it...

    what about those lurches and strong rolls to the right?

  6. pronouns on Look Inside A PC-killing WIPO Treaty · · Score: 1, Informative
    "Me and another EFF staffer and the Coordinator of the Union for the Public Domain created a heavily editorialized impressionistic transcript of the meeting (EFF mirror, UPD mirror)...."


    The subject pronoun should be "I", as in "I created a heavily editorialized....". Just think how silly "Me created a...." sounds to see the error.


    Unless you are Jarjar Binks.

  7. Re:Yes, much simpler than.. on BYU Project to Silence Computer Fans · · Score: 1

    hear, hear! my office mate made a quiet fan by buying a very large (to get enough CFPM after slowing it down) 12V fan and running it on the

  8. Re:authpf? on Port Knocking in Action · · Score: 1

    i tend to agree with m0rph3us0. but the password alphabet is bigger: consider port number a symbol, and delay between knocks a symbol. a letter is then the two symbols together: (#,t). so there are |#| * |t| letters, probably more than 36...

    (or count words with alternating symbol types)

  9. Re:Multiple kocks on Port Knocking in Action · · Score: 1

    good idea!

    in any case, some mix-up will be inevitable, just like packet collisions on a network can happen. same algoriths (random wait & retry) will be used.

  10. is this the first? on Linux Ported To Multi-Core DSP · · Score: 1

    is this really the first LINUX on a multithread CPU? Intel "Hyper-Threading" is regular multithreading that has gone through the marketing department.... has no LINUX implementation had access to an Intel HT cpu yet? what about the old DEC Alpha multithread designs - i believe they invented the technique back in about 1996 - were they ever instantiated in hardware?

  11. other semiconductors on LavaRnd: A Open Source Project for Truly Random Numbers · · Score: 5, Interesting

    audio circuits often use diode junctions in reverse-breakdown mode as a source of "white noise". couldn't we computer folks do the same? seems a similar idea to the the dark CCD technique.

  12. off-topic C++ on Obtaining Mainframe Experience w/o a Mainframe? · · Score: 1
    C++ does not really predate Mach: both were research projects at the same time, early '80s. C++ at Bell Labs; Mach at MIT. Mach went commercial (in Steve Job's NEXT project) before C++ went commercial.

    (i have no idea if Mach used C++.)

    surprise! young people are smart! YES THEY ARE - for anyone so say, "not bad for a group of third year undergrads" is to BELITTLE their intelligence. they can do it - don't belittle them with your lowsy expectations.


    why was this piece even posted? so some bright students read a bunch of hype material from the wireless industry and did an excellent job actually anayzing and developing the idea - this isn't what business economics majors do every semester?

    really, i think evil-doers will set the evil bit with pride, and that will be a real help!!

    MPEG2 has one of these on the Transport Stream level called "transport_error_indicator", which you set when there's no point in transmitting a packet but you transmit it anyway.

  16. perfectly healthy on Microsoft's Reaction to OSS Adoption · · Score: 2, Interesting

    the memo outlines perfectly healthy organizational function. it's exactly what MS should be doing. if those folks actually function that way, they've moved up a few notches in my esteem.

  17. Re:3 Bit Color? on New Display Technology to Compete with LCDs? · · Score: 3, Informative

    repeating above, there are sub-pixels: up to 100 cells per display pixel gives ability to graduate the color.

  18. correction... on New Display Technology to Compete with LCDs? · · Score: 2, Informative
    according to the article, the colors are generated by the distance between the transparent electrode and the reflective plate - it's constant gap that is maintained once set. this works by the gap being near to the wavelength of light you want to see: two reflections happen, one from the transparent electrode, the second from the metal plate. the light that has wavelength the size of the gap is reinforced when the two reflections combine, other light is partially cancelled because their waves don't line up just right.


    but it was good of you to think of the modulation rate based color method. BTW, did you know that modulation based color perception is a genetic trait? not all people percieve color from the spinning disk experiment. i am one that does not, and i was very frustrated when i was trying to get the experiment to work until i found out that some people are not sensitive in that way. folks in my computer club were programming their B&W monitors to show color using the technique before there were any color TV interaces.

    metals have an interesting characteristic, in that there is a certain amount of bending that can be done without damaging the crystal, in which case you can keep bending it back and forth forever.

    take a look at Torvald's manifesto (i don't have the link, which makes me a LAME poster) in which he initiated the LINUX project, and you will see that he was bummed that MINIX worked SO WELL! he wanted to have fun fixing more bugs than MINIX had!

  24. INSTRUCTION BANDWIDTH on Revolutionizing x86 CPU Performance · · Score: 1
    making heavy use of this instruction set level register mapping would DOUBLE the instructions for a program!!


    on chip, you could increase cache size and bandwidth to the prefetch, but yeah, that's more transistors (better spent elsewhere!).

  25. boundaries on Talk To a Convicted Warez Guy · · Score: 1
    have your ideas of intellectual property boundaries developed, perhaps in unexpected ways, since the criminal conviction? for instance, are concepts such as the GPL license and the BSD license more crisply defined in your thinking than before? do they matter more in your opinions now?


    i suppose another direction to ask this question might be: does the author's intent in releasing software figure differently in your thinking now? what did you think about author's intent before you were busted?
