  1. IMPORTANT: A solution already in the box. by niktemadur · · Score: 2, Informative · on Dangerous Apple Power Adapters?

    My wife's iBook power adapter malfunctioned a couple of months ago, it started to crackle and even let out a few sparks! The replacement runs for about US$80.00, a ridiculous amount for a product that is raising a stink in forums all over the web because of its' horrible quality.

    However, I decided to inspect the adapter, detached the A/C plug, which snaps on and off the corner of the adapter, and was horrified to notice it was thoroughly charred on the inside. Then, I vaguely recalled that a power cord came with the iBook, in the box. This is what I'm talking about: http://www.shentech.com/aprepog4ib65.html
    To my great relief, the new power cord snapped neatly into the corner slot of the adapter, and ran smoothly. It was the detachable A/C plug that was defective, not the adapter itself. Now, not only could we throw the defective plug where it belongs (in the trash), we also had made our device safe, as well as doubled the length of the cord, and saved ourselves $80.00 to boot! My wife and I were happy campers that day.

    So, if you have an Apple laptop, check this out for yourselves and I'm sure it will allow you to solve/avoid this exact problem, and even if it's not malfunctioning yet, do it now, no use putting your expensive computer at risk. Also, even if you've misplaced the box and/or cannot find the power cord, buy that instead, as it's price starts at around $10.00, saving you quite a bit of cash in the process.

  3. Re:LAME GPU by Doc+Ruby · · Score: 1 · on Impressive Benchmarks: Sorting with a GPU

    AGP (1x) does 254.3MBps, PCI (v1.0) does 127.2MBps. CD data is 172.4KBps. So PCI does 738 CD streams, while AGP does 1475. At 128Kbps, each stream IO is 192.4KBps duplex, so AGP: 1322 encoder streams, PCI 661 encoder streams. A P4/3GHz does 6GFLOPS, including host apps (OS, etc), while a $115 GeForce FX5900 does 20GFLOPS; a $470 GeForce 6800 Ultra does 40GFLOPS. Even at the slowest AGP and PCI speeds, and the fastest theoretical GPGPU speeds, the GPU is still slower than the bus, and 5 of those cards in PCI would have to do over 100 streams each to fill the bus, even leaving 25% PCI capacity for the host P4. That's over 500 streams for about $1000, which can't be done any other way I know of.

  5. Re:Need a more efficient PSU for my Neverball Box by atrus · · Score: 1 · on Efficient Power Supply Contest

    Those small power supplies for Mini-ITX systems probably aren't very efficient anyway, and they'd be undersized for a Celeron system most likely. Try looking for some Seasonic power supplies. They claim 80% efficiency, and in my expierience do actually live up to that claim (supply produces far less heat than cheapo supplies). Here is a random link from Pricewatch: http://www.shentech.com/sesssuto30ac.html. I've found them at Fry's before, they even had a rebate once.

  6. I'd go with HomePNA by uradu · · Score: 2 · on Non-Invasive Networking - HomePNA vs. HomePlug?

    Just because of price alone. You can get HomePNA 2.0 cards for $10 (just an example, do a search on PriceWatch for more), they're PCI, and they all use the same Broadcom chip so they're essentially the same card. HomePlug is A LOT more expensive at the moment and only seems to be available in USB right now. The other nice thing about HomePNA is that you can simply daisy-chain a bunch of computers together using simple phone cable, without needing a hub or anything, just like in the old coax days. I've heard some people having problems when running the network over their primary phone line (although many others haven't had problems). In that case simply use the other pair of wires for line 2--even most older homes are wired for two lines. Heck, just get two cards and try it out--if it works fine for you, you saved yourself a bunch of dough. If it doesn't, you're only out $20 (for two cards).

  7. My quiet case project : it's an answer ... sort of by Prozzaks · · Score: 1 · on Building Quieter Computers

    Well, it seem these days, most of the power user just care to get something like 200fps in Quake III. Why ? Beat's me ! I'm not on a quest to get the ultimate frame rate, I just want my box to be quiet as possibly can be.

    To help you understand my take on the subject, here is the background :
    My PC has the following components :

    • A OEM case
    • A 235W OEM power supply
    • ASUS P3B-F
    • Intel Pentium II rated 400Mhz @ 400Mhz
    • A cheap OEM SECC2 Heat-Sink made of aluminum
    • A 128MB CAS2 no-name DIMM
    • Two 32MB CAS3 Samsung DIMM slowing down my memory timing, but preventing the appearance of the all mighty evil SwaP
    • A ATI All-In-Wonder Rage128 16MB
    • A Creative SoundBlaster Live! Value
    • A Realtek 8139 Ethernet NIC
    • My beloved USR 56Kbps ISA Real Modem. Sorry but to me a component that uses CPU power to do it's processing instead of taking the load off is not worthy of being in my computer. Not to mention the M$ Win part...
    • A Creative 48x CD-ROM drive. It's the loudest damned thing in my computer when it's spinning
    • A Quantum Fireball AS PLUS 40GB (7200RPM) in a removable tray
    • A Quantum Fireball CX1 10GB (5400RPM) mounted inside the case
    • Of course the stupid old 1.44 MB floppy drive only used for booting Tomsbrt in case of emergency

    Soon to be :

    • A Adaptec 2940UW
    • A Diamond Monster 3D II for Glide games

    It turn out that the Quantum Fireball AS makes less noise than the Quantum Fireball CX1. I still have to figure it out ...

    I use my PC for :

    • Running Linux and learning as much as time allows me (Jez I had so much time when I was a student... Think of all the time I wasted in High-School running the evil W monster)
    • Doing some gaming i.e. : Diablo II, Unreal, UT, Undying (Although that thing is going to cost me a new box)
    • Spending numerous nights filling my brain @ Slashdot, Tomshardware, Anandtech, Arstechnica, StorageReview, Developper.Intel.com, and most importantly, hounding the web for all the case manufacturers and their take at a quiet box.

    As I'm writing this post, that is probably going to be the base documentation for my Silent Case Project, you're guessing that my sleepless night of browsing have not yielded the desired result.

    I've check out many options such as water cooling, moving the PC to the closet, returning to the forest where a PC is pretty far from your everyday quest for survival. None of them suits me.

    The objective of my project is to build a case that meets the following criteria :

    • A silent as possible
    • Accessible
    • Provides sufficient ventilation to maintain all the components running within thermal specs
    • Be light enough to be easily transportable (Let's not forget the Lan parties ;-)

    To attain those goals I have to :

    • Read all I can about noise, sound, aerodynamics, PC specs
    • Find suitable materials : A case is not just a protection against unwanted fingers and dust ; it must provide EMI shielding, proper grounding, resist to impacts, and fit into my conception of the king of object you want in your bedroom (If you were thinking about plywood and a box of rusted leftover nails, forget it)
    • Find the tools or the companies or individuals with the means to work the materials I choose to build the casing

    For the sound isolation I was thinking about some kind of foam. Mineral lint would be affective but that takes too much space and it's not the kind of thing I want beside my bed. Form the casing itself, metal is almost inevitable if you want EMI shielding and grounding. And as for you who wonder why I have not mentioned water cooling yet, the greatest source of noise is not my CPU cooler and your just moving the problem out of the case (Nice ; you have water heating up but unless your reservoir is like a bathtub or something you will have to transfer the heat for the water to the air).

    That about as far as I am. If you have any idea that might help me, please fell free to send me some bits forming ASCII characters at Prozzaks@operamail.com
