    Minimum post count please

    Well that's easy....just impliment that same minimum post count in Computing as well; it'd be like a gated online community ;-) -Chris

    most reliable notebook hard drive

    Not to say that they're not good drives, but a number of manufacturers were putting the ill-fated deathstar's in their desktop machines for a while to. I think that unless there's obvious manufacturering problems with one brand over another it has more to do wiith which they can get $3 cheaper in batches of 1000. -Chris
  3. PCP&C :::also:::: makes very quiet power supplies (Silencer Line), and as someone who has used PCP&C, Antec and Seasonic...and while they're all good, I still think PCP&C is a notch above the rest. -Chris

    Computer Engineering

    Now this is certainly a gross simplification, but here's how each might apply to computers: Electrical Engineers - How do we create faster gates? (MOS, BJT...etc) Computer System Engineers - How do we create faster cpu's using those gates? Computer Science - How do we create faster and more useful programs to run on those cpus? Each one builds on the others, and there's quite a lot of overlap between them. I was in a simliar situation to you and I chose the EE route just because it was a better program then the CSE. And of course, even if you get your degree in one thing, you might wind up doing something completely different. -Chris
  5. When it come to UPS' can get absolute steals on ebay. People through out perfectly good UPS equipment all the time on there....and because there's so much of it it goes for nothing. The trick is to get them to ship the UPS (or expansion chasis) without batteries (which are probably dead anyway) yet include all the hardware that came with the batteries (cables, lugs, quick connects, etc). All you need to do then is order new batteries from an electronics distributor (digikey), reuse all the existing cabling and you're all set. A few years ago i put together an APC 2200XL with 3 expansion chasis with 14 all new 20Ah batteries for about $800. -Chris
  6. One thing that you've got keep in mind is that the first thing most devices do (cordless phone, alarm clock, stereo, etc) is rectify the incoming AC into DC and then perhaps add a regulator of some sort to maintain the output at a set voltage over varying input conditions. It doesn't really matter if the device is getting a true sine wave input or step's still going to recify into about the same thing. The only issue I could see is that the step approximation used on most all UPS's is going to introduce a number of harmonics which depending on the quality of the output filtering on the UPS and the susceptibillity of the device may cause a problem. That being said though, most devices that would be susceptible are pretty well regulated and filtered internally; they have to be....even normal line power itself can get pretty dirty. -Chris

    Raid 5, just not worth the money?

    From the linked site: That being said i do recall seeing a hack to enable raid5 on windows pro....but who knows how stable it actually is. Yeah that's a different matter. I wouldn't run it on my only machine either....I still need/prefer windows for a lot of stuff. That being said, since I've moved to linux on the fileserver, it's been a heck of a lot less hastle. Samba really does do a better job then windows. -Chris

    Raid 5, just not worth the money?

    Well, wouldn't you need the server version of Windows for Raid5? That doesn't sound nearly as cheap to me... Also, if you use persistant superblocks (which you should) on linux raid, you should be able to drop the drives in another system with raid support and reassemble the array. -Chris

    laser printers

    Well, if you buy an HP LaserJet III off ebay, the only support you really need to worry about is the desk you place it on :-) Seriously though, my only experience has been with HP. -Chris

    ST3160023A S.M.A.R.T. values plummeted

    Personally, i'd just spend the $20 on a promise u100tx2 controller or something similar with 48bit LBA and not worry about it again. -Chris

    USB 1.0 in practice?

    Yep, that's what i was thinking of. Guess i read that a bit too quickly :-) -Chris

    USB 1.0 in practice?

    Not to nitpick, but the FX chipset predates the TX and VX. -Chris

    LAN cable, home-made

    Could the problem be that you're trying to crimp connectors onto a solid core cable? the RJ-45 crimp on connectors are generally intended for use in making patch cables, which would be using a stranded core cable. Solid core is generally used behind walls and what not as part of the permanent structured cabling system. Stranded core doesn't perform quite as well as solid core, but it's far more flexible making it better suited to short patch cables. -Chris

    Holy power supply Batman!

    FYI, those rated effciencies are generally at 70% load.....where effciency is at it's highest. It's quite possible it'll be lower on a lightly loaded power supply. Doing a bit of googling on power supply effciency indicates that many"experts" out there don't even know the difference between power factor and effciency ie, "Wow, this new PFC power supply is 100% effcient!". Sheesh. -Chris
  15. That depends on the type of battery technology used in the laptop, though I believe all the recent ones are Lithium Ion. Lithium Ion batteries loose a fixed percentage of their capacity each year as they age, regardless of how they're used. On top of that, they benefit from frequent charging and not the deep cycle discharge/charge that's most benficial to NiCads. More Info Here: -Chris

    So I'm building a File Server

    In the end, a server is just a computer. 211527[/snapback] Exactly......a computer....not just a collection of parts picked off the web and assembled, but rather a complete unit that's been extensively tested as a whole. I've done it both ways......assembled and purchased, and 9/10 it's the whitebox that's the quirky machine. I don't like servers to be quirky....i like them to be dull, and very boring :-) -Chris

    Which dual-layered DVD-R brand?

    Zark, which store do you order from? -Chris

    RAID1 is lame

    What it all boils down to is this: How important is uptime? How important is the data? How much risk are you willing to take? Sure a RAID setup backed up nightly to a NAS volume with weekly writes out to a tape autoloader with archieve sets stored off site going back years should cover just about anything, but does it make sense for the home? Heck no. For me, my biggest fear is a disk failure. Deleted files, thrashed partitions, etc can pretty much be recovered via utilities, provided you catch it early (before overwrites) and the disk is still good; pretty much all my snafus fall into this catagory. Compare this to an actual disk failure where I might have to spend a grand or so to send the drive out to a specialist to recover data, if they're able to at all. So, while I agree a RAID1 :::boot::: volume for a home user might not make much sense, I do use a RAID1 volume for my important stuff (documents, pictures, etc) and then periodicly write that stuff out to dvd. And that's the risk i'm willing to take. -Chris

    Cheap fileserver setup.

    What's the configuration of the network this file server is to be deployed on? Also, for any sort of buisness critical server (which it sounds like this one would most certainly be), I'd recomend something from dell, compaq, etc. While yes you'll pay more over something you put together yourself, you're getting a complte, tested package, tested firmware updates and patches....etc. -Chris

    Maxline lll vs. T7K250

    Depending on who you ask, the Maxline III's are either cherry picked DM10 drives, or DM10's with higher spec parts; I tend to believe the later. Either way, Maxtor seems to put more confidence in the Maxline III with a 5 year warranty Vs. 3 for the DM10. -Chris

    Video editing workstation

    Not to start a side holy war, but as was mentioned, why the 6800GT? Does the client have any use for 3D? IMHO, Matrox has always made the best Dual Head cards/software and are the best choice when 3D isn't required. And ditto on the dual CPU's, my dual PIII 850's would smoke an athlon 1.2Ghz when it came to MPEG-2 encoding and effects rendering. -Chris

    Overclocking, an economic decision?

    Had a 486 33Mhz packard bell running at 40Mhz for quite a long time....though that only required a few jumpers being changed on the board....nothing as radical as FS. Yeah, i don't bother with it anymore either, And i'm still kicking myself for buying 512MB of the overclocking ram rather then 1GB of the basic stuff. -Chris

    Gigabit switches & cabling

    Placement of the wall plates is key too......try to locate them in rooms such that anywhere anyone might place equipment in the furniture, you can reach a plate without crossing over a doorway. You should be able to cover most rooms with 1-2 plates. The Biggest mistake people make is putting plates in locations that fit their current furniture layout, but might not work as well in the future. Midway on walls @ 18" above the floor is the best. -Chris

    Gigabit switches & cabling

    Just to touch on a few points: 1. The 10Gbps specification now being drafted recognizes that CAT6 cable may be supported over limited distances (up to 10-15 meters, for use in datacenters); full 10Gbps support will require an augmented "CAT6A" cable with performance up to 500Mhz rather then the 250Mhz of CAT6. The 30% cost premium of CAT6 over CAT5E is only worthwhile if it actually buys you something :-) 2. It's not just cabling, but all connectors, terminations and installation practices must be CAT6 complaint as well. These can carry even a larger price premium then the cable. Personally, I think CAT5E is the way to go right now in terms of price/performance on a home structured cabling system. 3. Look into installing a proper structured cabling system for voice, data and cable. Leviton, Siemon, etc all sell "media centers" where you can consolidate all your wiring and cross connections. ie: For instance, I put a panel in the basement and ran two CAT5E and two RG-6 cables to each wall plate location. This gives you complete flexiblity in terms of connecting two computers, a computer and a phone, etc. The two coax allow one for cable tv, the other for a roof antenna, or a direct connection to a cable modem, wherever. The basic idea is that the cabling in the walls in permanent, and by connecting patch cables at the wall plates and the panel you can connect anything to anything. The residental cabling standard actually calls for two CAT5E, two RG-6U ::::and:::: two multimode fibers....but i think that's getting a bit silly :-) -Chris
