AMD64's throttle down their clockrate and voltage depending on load. I think their max TDP in most desktop situations is about 35W, which is somewhere along the lines of a 500MHz PII.
I've heard from another thread AMD64's also have P4-alike thermal throttling/shutdown as well, but I've yet to verify this.
He named a dubious looking (as a UK user) bid payments-only service and a professional, business-only service. PayPal are both of these (kinda; WorldPay's out of their league really), but they're not direct competitors; I couldn't use BidPay to sell services on my website, and I couldn't use WorldPay to sell the occasional item on an auction site.
50% on files that are ~10MB per minute is quite significant. It costs a few seconds per track, provides integrity checking, metadata support, and it's cheap to decode, so..
Required for me: FLAC, MusePack, Vorbis. In that order.
Nice to have: APE, WavPack, OptimFrog, MP3+APEv2 tags, and every other audio format I've seen in use (I mean, isn't that the entire point of a portable media player, that it plays all your media? Duh)
And even the nerds are fragmented between Vorbis, MusePack, AAC and lossless codecs like FLAC and WavPack. I'd really like to see player developers work to support a similarly wide range of codecs though, rather than expect everyone to pick just one; they all have different advantages/disadvantages, there is no one size fits all.
AND you don't even have to create the basic getter/setters! Ruby classes have a built-in class method that creates them dynamically:
class Customer
attr_accessor:first_name,:last_name end
What's also handy is you can write your own methods which work like this to dynamically generate repetetive blocks of code for a class or object. ActiveRecord makes great use of this with things like:
class Author < ActiveRecord::Base
has_many:articles
has_one:account end
class Article < ActiveRecord::Base
belongs_to:author
has_and_belongs_to_many:categories end
Which then gives you things like Article#author (and Article#author=, letting you change the relation by assigning another Author object to it), Article#categories?, Author#articles, Author#articles?, Author#article_count.. mmm, metaprogramming tastic.
Adoption seems healthy here. Should I stop using FreeBSD too because it's not as popular as Linux, or Windows perhaps?
Ruby's mature, portable (do Python's threads work in DOS?), easily popular enough for general use, has excellent support, and I find it a hell of a lot nicer than Python. Why shouldn't I use it, especially when I see so much more interesting development there?
There are a bunch of important looking fixes for ppc64 and amd64, a fix for a swapd lockup, fixes for xfs and ext3.. most people should probably upgrade fairly quickly, I'd say.
Recommendations? I'm a bit disappointed with KAV; I keep getting systems to fix which are full of viruses despite even running the performance sucking KAV monitor. Gah.
Eh? Does anyone care about karma any more? It's capped at "Excellent", which mine has been constantly for as long as I can remember. The entire point of karma and user accounts is to help identify good, reliable posters; telling people to post stuff like this ac just helps the trolls blend in. Work with the system, such as it is, don't just negate 90% of it, please?
"0. Dual head forces a 'primary, secondary' effect. ie: you're always looking forward or left. It's very unbalanced. I would prefer a tripple-head setup, to keep things balanced."
Slightly left, and slightly right here. I do have a big desk though.
"1. DVDs/most video players would freak out (split video between 2 monitors, only show half the video, stretch, etc)"
Full screen stuff should stick to it's own monitor unless you've set your multimonitor mode to Span instead of Dualview (nVidia's terms, dunno about ATi etc).
"2. Video games freak out"
Again, try Dualview, and avoid resolution changes to the primary display or your secondary will move about (harmless, but annoying).
"3. Second monitor was usually the old one after having bought a new one. I couldn't stand looking at it in comparison to the new one."
My second's my new TFT; works nicely next to my 19" CRT. I usually run Opera and Samurize with a few log tails and system monitoring on the TFT, and SSH etc on my CRT; that way I make best use of the colour reproduction and ClearText on one, and the more comfortable brightness on the other.
"4. I have a very very nice desk. I sanded and finished it by hand. I don't like covering it with CRTs"
I have a huge desk, and I'm happy to cover it, but the useful space under and behind the TFT's definately handy. I'd be more concerned about the weight with 2 CRT's tbh, if only because it's a struggle to move anything over about 17".
"5. CRTs side by side create magnetic interferance and distort each other"
Doh. Aren't bigger more expensive CRT's shielded to prevent that?
"6. Windows (nVidia) support for dualhead, atleast with my card at home (GeForce 2 MX), absolutely sucked. It insisted on treating it as 1 large display, which stretches wallpapers. It also failed to see the secondary monitor 1/2 the time. Windows that were on the 2nd monitor previously, when the 2nd monitor wasn't found, would be lost in unusable screen space. The list goes on."
Windows is fine here; I have the option of Dualview (two discrete displays), Vertical and Horizontal span (1 large display), and Clone. I can switch monitors on and off without problems, games and video players are perfectly happy; about the only thing that's a bit ropey is overlay in some programs (notably MPC), which can cause (application) crashes and missing video if you drag them between monitors while they're playing.
Er, the Athlon MP's claim to fame was it was for SMP systems; nothing to do with "mobile processor":
"The AMD Athlon MP processor is a seventh-generation x86 processor designed for high-performance multiprocessing servers and workstations.
A key advantage of AMDs multiprocessing platform is Smart MP technology, which greatly enhances overall platform performance by increasing data movement between the two CPUs, chipset and memory system."
My Zaurus gets used ten times more than my iPAQ. 9 hours battery life, kickass VGA display, reasonable ickle keyboard, SD and CF. Lack of built in BlueTooth and WiFi's disappointing, but with a GB of SD it's not much of a hardship.
Crappy software? I wouldn't know, I've never used Sharp's Zaurus stuff (they have Opera? Since when?). I use pdaXrom, although OpenZaurus looks interesting if they ever port it to mine (SL-C860)
Why would I want a USB drive caddy as a backup medium for live servers in the middle of a data centre, where I can spread backups across any of about 10 RAID-1 arrays? A flashdrive with no moving parts I can almost buy, but as soon as you start talking HD's.. I have perfectly good SCSI ones, thanks.
"RAID 0 (mirror) your hard drives. You will have hard drives fail."
RAID-1, you mean; RAID-0 is striping (hence 0 redundancy). And yes, anything even vaguely important should be on a RAID array in addition to backups. RAID doesn't help much when your controller freaks out or you hit a fs or user error.
"Buy decent drives."
Unless you're willing to trade off warranty, latency and quality against sequential transfer rate and storage, this means go SCSI.
"Go overkill on cooling."
Buy decent fans (twin ball bearing or so?) and monitor them. If noise isn't a concern, this might be a good application for Delta's more extreme fans:)
"Check the fans on your CPU too. They also go out frequently."
On a 1U rackmount, your case fans will most likely be your CPU fans too. Pair of Opterons? Fit passive heatsinks and a bunch of 15kRPM case fans, should be sorted.
"Backup to a USB hard drive."
Do they make those in 64GB versions now? No? I'll just use another RAID array then, thanks.
"File servers don't need much RAM."
Depends what your files are and how you're accessing them; do you want to have to hit disk for every access? With a lot of clients (which is kind of the point with a file server), a lot of memory is practically a requirement.
"Dual CPUs are a godsend. Sometimes an application will peg the CPU. This often makes the server appear to be hung."
A good kernel should avoid this, and HTT can help, but when you can get a well kitted-out 1U dual 1.4GHz PIII for under £500, why not?
"Also, be wary of Dell. They use non-standard power supplies, so if your PSU goes out, you can't hop down to the local computer store and buy a replacement."
My local computer store doesn't sell 1U PSU's. Dell do however support redundant ones; I'll take that over downtime while I replace a single one, however cheap/available.
Don't be surprised when the guy who's server you're resting your laptops on comes to unrack his machine and unplugs yours to get at it. If you're (un)lucky he might just try to gently drop them onto the next spare U down, but two laptops.. well, at least one would probably end up on the floor.
Seriously, please don't try this shit on a shared rack unless you've got some kind of reasonable mounting system. The owner of the server you're resting on is *not* going to show your systems a great deal of respect if they're in his way and obviously not important enough to be racked properly.
"I installed a Thunderbird 1.4, and using a $50 Alpha heat sink (and fan of course) I couldn't get that darned processor cooled enough. It ran so hot I had to underclock it to 1ghz..."
It's not AMD's fault you don't know how to apply thermal paste properly. My 1.4 Tbird's living under a £5 Thermalright SK6 and it's perfectly happy running at full load 24/7 (with a VIA chipset, no less).
We have a bunch of those around here; they're called "public schools":/
"maybe a dual Opteron rig with 16GB would be able to handle a good bit more."
You'd probably be better off buying a second 4GB Opteron and having 2, 2-way 4GB Opterons with their own drives, rather than a single 16GB one. Costs about the same, probably performs about the same, but also gives you some redundancy and lets you share network bandwidth about more.
The last DVD drive I bought was £15.. in my experience, US stuff typically converts $ = £ despite the 50% value difference; you're complaining about probably less than £10 of equipment, then? Is the US a lot poorer than I thought?

Try again.
Don't forget NOCHEX, who have features suited to using it to actually sell things, you know, automatically.
Dabs do a dual Opteron mobo for about £150, if you can do without PCI-X, and don't mind memory only being attached to CPU #0.
50% on files that are ~10MB per minute is quite significant. It costs a few seconds per track, provides integrity checking, metadata support, and it's cheap to decode, so..
Plus you generally get metadata support with lossless codecs.

No, I'm not holding my breath either.

Heh, I used to play TF on my A1200; 50MHz '030 without a GFX card initially, but later on a 160MHz 603e and a BVision GFX card. Permedia 2 p0w4r! ;)
Nothing beaten the sense of team play since. Shame I lost interest and came back to find it had pretty much died; never really tried TFC though.
Slightly left, and slightly right here. I do have a big desk though.
