  1. Re:waiting on Multicore Requires OS Rework, Windows Expert Says · · Score: 4, Insightful

    Well, with the rise of the SSD, that's no longer as much of a problem. Case in point - I built a system on the weekend with a 40GB Intel SSD. Pretty much the cheapest "known-good" SSD I could get my hands on (ie TRIM support, good controller) at AUD $172, roughly the price of a 1.5TB spinning rust store - and the system only needs 22GB including apps.

    Windows boots from end of POST in about 5 seconds. 5 seconds is not even enough for the TV to turn on (it's a Media Center box). Logon is instant. App start is nigh-on instant (I've never seen Explorer appear seemingly before the Win+E key is released). This is the fastest box I've ever seen, and it's the most basic "value" processor Intel offer - the i3-530, on a cheap Asrock board with cheap RAM (true, there's a slightly cheaper "bargain basement" CPU in the G6950 or something). The whole PC cost AUD800 from a reputable supplier, and I could have bought for $650 if I'd wanted to wait in line for an hour or get abused at the cheaper places.

    Now, Intel are aiming to saturate SATA-3 (600MBps) with the next generation(s) of SSD, or so I'm told. Based on what I've seen - it's achievable, at reasonable cost, and it's not only true for sequential read access. So if the IO bottleneck disappears - because the SSD can do 30K, 50K, 100K IO operations per second? Yeah, I think it's reasonable to ask why we wait for the computer.

    Not that I think a redesign is necessary for the current architectures - Windows, BSD, Linux all scale nicely to at least 8 or 16 logical CPUs in the server world, so the 4, 6 or 8 on the desktop isn't a huge problem. But in 5 years when we have 32 CPUs on the desktop? Maybe. Or maybe we'll just be using the same apps that only need 1 CPU most of the time, and using the other 20 CPUs for real-time stuff (Real voice control? Motion control and recognition?)

    And they deliberately attacked the problem noted in TMMM - that of communication and ramp-up - by seating everyone in the same room(s). And yes, working on independent problems. And those problems were not already late, in that the schedule had not yet started (TMMM is about adding people to an existing, complex project that is already running and having the communications, ramp-up, skills transfer and other sundry distractions causing an increase in work required that is greater than the increase in available effort).

  7. Re:Exactly what you're doing on Long-Term Storage of Moderately Large Datasets? · · Score: 1

    While it's true that the server CPU is more than capable of performing the calculations, your analysis misses more than one critical factor.

    When writing data to a hardware RAID set (of any sort) the data is sent from main memory across the system bus(es) exactly once, potentially in a single operation.

    With software RAID, the total amount of data is more (the parity data, if not multiple copies for RAID 1/10) and this has an impact on memory bandwidth utilisation, northbridge and PCI utilisation and certainly the number of operations issued by the system to the disk controller(s).

    Dave562 already pointed out BBWC, which is also transportable to a new server with the disks in the case of an extreme failure, and the increased use of server CPU (and memory, system bus, network and disk) of virtualisation.

    600ml in particular is very close to your "20 oz" (591ml) bottle - so much so that it would be trivial to label and sell the 600ml version as a 20 oz bottle (woo hoo, 9ml for FREE).

And only Office can decrypt, and the RMS allows the author to block the ability to do things like edit, print or forward the document to someone else.

    Some customers like the idea. When we implement it, rule #1 is "You no longer have sole control of the document". IIRC, there are ways to set RMS up so that internal people always have access - it'd be strange if that was what was broken.

    Or how about creating those pesky management template files? What's that? Oh...You have to create those manually using some cryptic schema.

    Hurr hurr. Those pesky templates! It's a cryptic schema - one that bears more than a passing resemblance to an X configuration file, really (it's about the closest analogue I can think of off the top of my head). It's not that bad. If you do it often you'll have your own files to use as a template. Otherwise, perhaps someone, somewhere will come up with a way to search through thousands of documents written before, on a global network? Nah ... never happen.

    And what if I want to reset my template to default old values? Oh, I'm sorry... that's not possible.

    The template is never changed. Only the policy carries the value. In a proper policy, removing the setting reinstates the default value.

    What I'm trying to say, is that AD has it's place. But when you need to do something that microsoft has not thought about, it get's very quickly back to editing regitry, creating scripts and hacking away in general.

    If you need AD'like functionality on Linux/bsd whatever, check out cfengine which is a policy based management engine.

    And when you admin a Linux, BSD or similar system, and you have to do something new, it "get's (sic) very quickly back to editing configuration files, creating scripts and hacking away in general". CFEngine is (probably, I haven't used it) good; does it come with sane defaults, and you just click some buttons / type a command to get all the OOB configuration applied? And it's done on a regular, hands-off schedule? AD's huge advantage in configuration management is that all this is in-box - and it tries to enforce good practice even without the admin knowing. Installs with sane defaults, and every corporate Windows OS from the last 10 years (2000, XP/2003, Vista/2008, 7/R2) can join the AD and participate in GP.
