    The core problem, of course, is that many workplaces (particularly offices) have no adequate way to measure employee productivity and thus use "time spent staring at your desk at a VDU" or similar as a surrogate indicator of performance.

    The most productive people I know are the ones who regularly take short breaks. Even when we're in the middle of a crisis, our bosses will insist on us taking short breaks, and as an ex-smoker I still take fag breaks - you'd be amazed how many eureka* moments you can get whilst standing outside the office looking at a flower bed or waiting in line for a coffee wondering what the difference between two roasts is.

    Just like too much coffee can ruin your concentration, staying on the same problem for too long frequently makes you blind to the actual solution.

  8. Swap files may grow, but the speed of hard drives doesn't scale along with everything else. Take a good platter-based drive and you're lucky to see reads/writes of 20MB/s assuming little to no HDD contention, especially since swap is typically highly random non-sequential 4k access. RAID that up or us an SSD and you might get 50MB/s. Lets say you have a 512MB swap, as I do, it'll take 10s to read the whole thing. Take a 512GB swap (like one poor server I found at work - someone was following the appallingly stone-aged adage about swap=mem*2) and all of a sudden it's going to take you 3 hours to read back all that virtual memory.

    Compare that with some old memory, say some DDR-333, which has a transfer rate of over 2GB/s. Compare with the DDR3 in my workstation, capable of 12GB/s.

    Back when we were limited to miniscule amount of memory, lots of swap made sense because memory was horrifically expensive and it didn't take *that* long to read/write to, because the total amount of memory was still fairly small in comparison. But these days you're looking at wait times of 30 minutes or more if you want your entire swap space to be double your memory and to be used by the OS.

    Stick with a small swap file and not much crap ever gets written to disc, saving you the horror of having to reset a server for the umpteenth time when it's been grinding on its system disc for five minutes trying to page in the OOM killer.

  13. Re:Do companies really use Big Iron anymore? on NASA Unplugs Its Last Mainframe · · Score: 1, Troll

    Working in a company that ditched the last of its mainframes just as I arrived (and was lucky enough to get to talk to some of the awesome IBM techs who were decommissioning the hardware), this lovely excerpt from The Cryptonomicon is just as apropos for mainframes as it is for bandsaws and Vickers machine guns:

    Now when Bobby Shaftoe had gone through high school, heâ(TM)d been slotted into a vocational track and ended up taking a lot of shop classes. A certain amount of his time was therefore, naturally, devoted to sawing large pieces of wood or metal into smaller pieces. Numerous saws were available in the shop for that purpose, some better than others. A sawing job that would be just ridiculously hard and lengthy using a hand saw would be accomplished with a power saw. Likewise, certain cuts and materials would cause the smaller power saws to overheat or seize up altogether and therefore called for larger power saws. But even with the biggest power saw in the shop, Bobby Shaftoe always got the sense that he was imposing some kind of stress on the machine. It would slow down when the blade contacted the material, it would vibrate, it would heat up, and if you pushed the material through too fast it would threaten to jam. But then one summer he worked in a mill where they had a bandsaw. The bandsaw, its supply of blades, its spare parts, maintenance supplies, special tools and manuals occupied a whole room. It was the only tool he had ever seen with infrastructure. It was the size of a car. The two wheels that drove the blade were giant eight-spoked things that looked to have been salvaged from steam locomotives. Its blades had to be manufactured from long rolls of blade-stuff by unreeling about half a mile of toothed ribbon, cutting it off, and carefully welding the cut ends together into a loop. When you hit the power switch, nothing would happen for a little while except that a subsonic vibration would slowly rise up out of the earth, as if a freight train were approaching from far away, and finally the blade would begin to move, building speed slowly but inexorably until the teeth disappeared and it became a bolt of pure hellish energy stretched taut between the table and the machinery above it. Anecdotes about accidents involving the bandsaw were told in hushed voices and not usually commingled with other industrial-accident anecdotes. Anyway, the most noteworthy thing about the bandsaw was that you could cut anything with it and not only did it do the job quickly and coolly but it didnâ(TM)t seem to notice that it was doing anything. It wasnâ(TM)t even aware that a human being was sliding a great big chunk of stuff through it. It never slowed down. Never heated up.

    In Shaftoeâ(TM)s post-high-school experience he had found that guns had much in common with saws. Guns could fire bullets all right, but they kicked back and heated up, got dirty, and jammed eventually. They could fire bullets in other words, but it was a big deal for them, it placed a certain amount of stress on them, and they could not take that stress forever. But the Vickers in the back of this truck was to other guns as the bandsaw was to other saws. The Vickers was water-cooled. It actually had a fucking radiator on it. It had infrastructure, just like the bandsaw, and a whole crew of technicians to fuss over it. But once the damn thing was up and running, it could fire continuously for days as long as people kept scurrying up to it with more belts of ammunition. After Private Mikulski opened fire with the Vickers, some of the other Detachment 2702 men, eager to pitch in and do their bit, took potshots at those Germans with their rifles, but doing so made them feel so small and pathetic that they soon gave up and just took cover in the ditch and lit up cigarettes and watched the slow progress of the Vickersâ(TM) bullet-stream across the roadblock. Mikulski hosed down all of the German vehicles for a while, yawing the Vickers back and forth like a man playing a fire extinguisher against the b

    Same here - I used to get all my computer components from scan.co.uk but their customer service was appalling. Negotiating a replacement took a battery of emails and phone calls and paying my own postage ending with a "the item is fine, we're charging you £xyz for costing our time" and I'd either get back the same item still faulty, or a silently-replaced (diff. serial number) functional item. Before I shopped at scan, I used aria.co.uk who refused to ship me an order I never received, despite having no tracking information for the parcel. Had to take those fuckers to the small claims court.

    With amazon, I say "it's broken, I want a refund", I get a refund. When I got a DOA NAS unit, the replacement was there the next day along with the "here's a DHL coupon thing, let them know when you're ready to send the original back and they'll pick it up from your door. Coupon is valid for weekend pickups too!". As with you, if the cost of the postage is too much (as with a lot of DVD's) they'll say "just keep it or throw it away".

    Same here - central London and just moved into a house without a phone line and a virgin 50Mb pipe. We got rid of Virgin when we noticed that pings to most servers in europe were 100-150ms and that sites like iPlayer and youtube appeared to be throttled down to 1-2Mb/s download. The Virgin-supplied hardware was also complete and utter dross (two or three reboots a day if you used wireless, and you weren't allowed to replace it with your own kit). People I know on BT have the exact same experience.

    Switched to ADSL via BeThere, "only" 24Mb/s (line actually syncs at about 21Mb/s) but pings are in the 20-30ms range and there's no capping going on so it feels much faster.

    In summary, people aren't going for these "fast" connections because most people tech-savvy enough to utilise a >25Mb/s pipe are also tech savvy enough to know that service through BT or Virgin is going to be piss-poor throttled arsebiscuits.

  18. Another lacklustre review... on Entry-Level NAS Storage Servers Compared · · Score: 1

    ...for my needs anyway, so hopefully I can add something to the discussion. I'm one of those traitors who traded a homemade linux NAS for an off-the-shelf model and went through quite a few models before I found one I was happy with.

    My initial file server was built into a cheap 4U rackmount and a couple of 3ware cards and provided sterling service. However, it was exceptionally loud and very heavy, and sucked up a fair amount of power. When you've moved house as often as I have, you start to think about whether you really need a 40kg server just to put 8 hard drives in (and another server to back up to).

    So cue me looking for a smaller case that I could cram a mATX or mITX mobo into, and rely on linux softraid; there aren't really any that aren't rackmount. A couple of nice ones have come out recently like the Lian Li V354 (six bays and available in a very fetching red as well as black and silver) and the Chenbro ES34169 (four bays w/ hot-swap caddies) but I needed eight bays... so I started to look at the NAS market.

    Once I could afford it (don't get me wrong - NAS units are colossally overpriced for what they are) I got myself a NAS chassis. I'd bought a Synology DS410 for a client before and it was reasonably nice kit (PPC processor and four non-hot-swap bays) and the synology OS was OK... but adding third-party apps to it was a bitch (you needed to hack the bootloader) and the shell was gimped. I returned the DS410 I bought for myself as a test (was planning to donate it so my sister as an engagement present once I'd evaluated the OS) and bought a QNAP TS-419P - also four bays but run on a 1GHz ARM processor.

    The ARM processor was, sadly, anaemic. The QNAP OS didn't allow RAID10 at the time (you could set it up on the command line using conventional mdadm commands but then couldn't manage the volume from the web GUI) since QNAP were under the delusion that "RAID6 is just as fast and more reliable!" - wrong. Thankfully they've now seen the error of their ways. Hence volume creation and write speed was limited by the processor (it was on the Synology too, but less so since the PPC was more powerful). I think I could get writes over CIFS at about 20MB/s on a good day, considerably less if I used SSH or rsync (which I use all the time). So, not good enough. Which is a shame since as a British geek who grew up on a school Acorn Archimedes (and had a former colleague of Sophie [Roger] Wilson's as a flatmate before he drank himself to death) I'm naturally a fan of ARM processors. The only other real difference between the DS410 and the TS-419P was that the QNAP was noticeably quieter than the Synology, despite the fact the spec sheet led me to beleive the opposite would be true. I think the latest model in the 419 line has a 2GHz ARM processor so should be considerably faster.

    So I looked at the x86 range. As much as I hate the Atom, for a NAS they're adequate. I sent the TS-419P up to my sister and bought a TS-859 Pro+ which uses a 1.6GHz dual-core + SMT Atom D525 and a 1GB SODIMM (which I later upgraded to 2GB) and the experience was instantly better. Across a six-disc RAID5 I got CIFS writes of about 100MB/s, and now that it's got eight drives in RAID10 (i.e. much less CPU overhead for RAID) I can get that up to 150MB/s with the two bonded gigabit ethernet ports; the bottleneck here appears to be smbd itself since with multiple transfers I can max out both interfaces at about 220MB/s. I figure there's something single-threaded in samba (or at least QNAP's version of it) that'll bottleneck the speed of a single transfer, but 150MB/s is easily fast enough for me at home. Amongst other things I use it as an iSCSI baby SAN for my ESX testbed. Noise-wise, the 859 i

Cow shit > methane > engine > exhaust heat.

    So he hit upon piping the waste heat from the engines into houses to supplement heating systems. Running waste heat along a mile of pipe from the farm would be wasteful, so instead they're just pumping the methane into a new engine installed within the village and piping the heat out from that.
