  2. Lightweight tech for lightweight spec on Low-Power Home Linux Server? · · Score: 1

    I'm using the same web server I have since 2000 - a Pentium MMX running at 233 MHz with 128 MB of PC133 SDRAM. The hard drives and RAM have been upgraded over the years of course; now it features 320 GB of SATA space thanks to a SATA PCI card. I took out the video card because the system runs headless.

    Power draw with both drives running? 14 watts. 100% CPU usage? 16 W.

    It serves quite the web page too!

    On the topic of thrones! You'll want to use one of Lenovo's new laptops as a cat box liner.

    Stay away from Lenovo G530, they emit the loudest beep you will ever have the misfortune of hearing EVERY SINGLE TIME you plug in or unplug the AC adapter. The beep comes out the "PC Speaker" output of the onboard sound. You can turn all sound channel volumes down to 0% and mute everything, and the volume of the power beep will only be reduced to ridiculously loud.

    Lenovo forums and phone calls state that this is not a bug, and will not be addressed in any software or firmware updates.

    On Windows XP and previous versions, the cause of SMB browsing in Explorer being slow on a LAN is because the Windows SMB service buffer defaults to a hilariously small value. The SMB packets get broken up into tiny fragments which compounds the slowness of the already-chatty protocol.

    To fix, simply increase the buffer size. Keep it equal to your MTU or set it a bit larger and let the TCP stack deal with it. After increasing the server's buffer size, I found that a directory full of image files that took two minutes to load up on an art workstation now takes less than a second to display.

    The following .reg file increases the buffer size to 2048 bytes in Windows XP and 2000:

    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters]
    "SizReqBuf"=dword:00000800

    To do it from the command prompt and/or a batch file:

    REG add HKLM\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters /v SizReqBuf /t REG_DWORD /d 0x800 /f

    Windows Vista uses SMB2 which claims to be more efficient protocol-wise; no clue if they increased the buffer size. Check before editing!

    You can copy the two driver files (%systemroot\system32\uexfat.dll and %systemroot%\system32\drivers\exfat.sys) from a Vista installation into the same place in Windows XP or 2003, and by adding a few registry entries (search the web for "exFAT File System Driver", I will not link to random blogs here) you enable full support for it.

    This trick works right now with Vista SP1. <tinfoilhat>MS could still disable the drivers from executing on anything lower than Vista in a future update</tinfoilhat> but you should still be able to use the present driver revision to access exFAT on XP/2003.

    Actually, the dust blows itself. It gets charged up by ultraviolet light during the day and the solar wind at night. Because there's no air to help neutralize the dust particles, they jump around like House of Pain. From the fount of all knowledge:

    Positive charges build up until the tiniest particles of lunar dust (measuring 1 micrometre and smaller) are repelled from the surface and lofted anywhere from meters to kilometers high, with the smallest particles reaching the highest altitudes. Eventually they fall back toward the surface where the process is repeated over and over again. On the night side the dust is negatively charged by electrons in the solar wind. Indeed, the fountain model suggests that the night side would charge up to higher voltages than the day side, possibly launching dust particles to higher velocities and altitudes

  9. Re:Wait a minute... on Our Moon Could Become a Planet · · Score: 1

    You forget that you're talking about enormous balls of molten rock and not solid billiard balls.

    Once upon a time, there was a small planet in orbit around the sun in basically the same orbit as Earth. Due to gravitational instabilities it swung closer and closer to Earth until a relatively low-speed impact occurred. If this planet had come from farther out in the solar system, its impact speed would have been much higher, with a less fortunate outcome (and we wouldn't be here to talk about it).

    In the article you pasted and others describing similar models, you can see that the impactor is completely disrupted. The impact energy is enough to liquify and tear a ball of rock the size of Mars to smithereens, but not enough to destroy Earth. The lighter parts of the impactor fly off into space and blend with the crust/mantle debris splashed off of Earth, and the impactor's heavy metallic core sinks and merges with the core of Earth.

    The extreme heating of the impact drives off most of the volatile substances (water, methane, ammonia, carbon dioxide...) that are dissolved in the now-liquid rocky material that was blasted into orbit. This accounts for the Moon's relative lack of volatiles, surface rocks that are similar to ones from Earth's mantle, and tiny iron core, while Earth has a thin crust and oversized metallic core.

    "The PACER project, carried out at Los Alamos National Laboratory in the mid-1970s, explored the possibility of a fusion power system that would involve exploding small hydrogen bombs (fusion bombs)--or, as stated in a later proposal, fission bombs--inside an underground cavity.

    The proposed system would absorb the energy of the explosion in a molten salt, which would then be used in a heat exchanger to heat water for use in a steam turbine.

    [...]

    As a power source the system is the only one that could be demonstrated to work using existing technology. However it would also require a massive supply of nuclear bombs, making the economics of such a system rather questionable."

  11. Most artists never see this money on Canada's CD Tax Out of Hand? · · Score: 1
    First off, it's not a tax, it's a levy. Taxes are collected by the government and have public oversight. The money from this levy goes directly to a private organization which then distributes it as they see fit.

    From Canadian Private Copying Collective:

    What is the distribution methodology?
    The distribution process adopted will ensure that royalties are fairly distributed to the tens of
    thousands of rights holders whose recorded music is in current use.
    Since information is not available concerning exactly what tracks of recorded music are copied,
    CPCC has used the two most comprehensive available sources of information - data indicating
    the recorded music that is sold in retail outlets in Canada and data concerning the recorded
    music that is broadcast by commercial radio stations and CBC. Airplay and sales are weighted
    equally.
    Internet downloads are not currently used as a basis for distributing private copying royalties as
    there are no data available at this time. Airplay and sales data are believed to provide the best
    available indication of the titles that Canadians typically copy for private use.

    Independent artists with no promotion, no radio/TV play, no licensing (songs in movies, etc.), and no retail sales stand a snowball's chance of getting their share.
  12. Re:Clarify on Canada's CD Tax Out of Hand? · · Score: 4, Informative

    I went to school in Canada to be an audio engineer. I know about the workings of the Canadian recording industry.

    SOCAN (the Canadian equivalent of ASCAP/BMI) handles royalty collection and distribution for Canadian music authors. If you're a Canadian composer, songwriter, or lyricist, you must do this to get royalties:
    1. Apply for membership with SOCAN
    2. Register your copyrighted works
    3. Sit back and wait
    You don't have to be owned by a record label to get your royalties. Also, SOCAN has arrangements with other performing rights organizations around the world, so if your music is played in the USA, or Germany, or Japan or whatnot, you'll still get royalty payments from SOCAN but on the accounting it states that the money is coming from that territory.

    Royalties are only paid to the "writers" and the "publishing company". The "writers" are composed of the songwriter (who does the music) and the lyricist (who writes the words). A songwriter and lyricist can be the same person. Usually it gets split 25% songwriter/25% lyricist/50% publisher respectively, which means that if a composer wants to get more money, they start their own publishing company.

    There are simple yet comprehensive materials available on SOCAN's site. Quick links:
    *SOCAN Overview for Music Creators and Publishers
    *How your music makes money
    *Private Copying Royalties update

    Up until recently, the money collected from the media levy has sat in SOCAN's accounts while writers and publishing companies fought viciously to get it all for themselves. Seems the writers have won; the "private copying royalties" now go 100% to writers by default. This of course doesn't stop publishing contracts from specifying that lots of money goes to the publisher...

    By the way, I finished the audio engineer training, said "I don't want to do this as a job" and have just opened a computer repair shop. I'll be selling those taxed CD blanks soon enough...

    Nichia Corporation in Japan is about to start mass production of violet laser diodes, and single-layered disks using these 400 nm lasers have capacities of around 13-16 gb.. The product info page for this FMD-ROM thing specifically points out that the new drives are backward compatible with CD and DVD media (lasers of shorter wavelength can read media designed for longer wavelength) - while it's probably there to avoid scaring people off with proprietary stuff, it introduces further mystery.
    Now, this 140 gb/10 layers = 14 gb per layer disk is announced - is this the first of the upcoming wave of violet laser products? I'm just waiting for a violet laser pointer :)
