  1. Re:Funny on Intel Details Power Management Advancements in Haswell · · Score: 3, Insightful

    It's mildly amusing that Windows 8 is the first version to gain dynamic ticks, something Linux has had working since around 2007.

    Its also mildly amusing that Windows has always trumped Linux in battery life, despite not implementing this power saving feature.

    Windows has always trumped Linux in batter life, you claim? That seems rather sweeping, whereas reports from the field seem mixed, with a significant number in fact reporting an advantage for Linux. I think it depends on a number of factors, including how much access Linux devs have to power management specs for a given OEM chipset. And there have been occasional regressions indeed. These get picked up pretty fast these days and usually corrected after a kernel bump or two.

  2. Re:Amdahl's Law on Power consumption... on Intel Details Power Management Advancements in Haswell · · Score: 1

    Notice how the display is quickly dominating the power consumption? The whole ARM vs. x86 power consumption bit is bunk.

    Whoa, I think you're getting a little ahead of the curve there. Try running a moderately intense game and watch the battery drain.

    I was running Windows the other day and it's just amazing how much it resembles KDE. Of course it hasn't got quite the same fit and finish and a bunch of features are missing, but hey, give Microsoft a chance.

  4. Re:Intel already realized where their market is on Intel Details Power Management Advancements in Haswell · · Score: 1

    They've been trying for years, and what do we get.. Atom? That's not even close... they need to drop power consumption by an order of magnitude to compete.

    True, this has been going on way too long to be explainable by incompetence or lack of focus, though there certainly was some of the latter in the past. What is the problem? Maybe this is it: as transistor count drops the relative cost of CISC decoding circuitry goes up, way up. Or?

  7. Worth the money a long time ago on Are SSDs Finally Worth the Money? · · Score: 1

    SSDs have been worth it for years on desktops and portables, for the speed, low noise and low heat/power. But not for mass storage, only because of the cost. IMHO it will be decades before rotating media is completely displaced in the latter, if ever. But SSD is moving steadily down the food chain, and certainly is the preferred solution for personal use unless budget is really tight.

    My solution: I run my workstation root filesystem on a modest sized SSD including my home directory and keep the big stuff like photos on rotating media, spun down. This is really easy on Linux, just install noflushd. You do not want to swap heavily in this situation, it will quickly eat the SSD, so have plenty of RAM. Not that that's the least bit unusual these days.

  8. Re:Google is evil on Alibaba Says Google Threatened Acer With Banishment From Android · · Score: 1

    What I don't understand is how Aliyun can even sell it. Not the mechanism by which they get money in exchange for some code, but how anyone would willingly pay these people for something they can get for free. What exactly is Aliyun adding to the Android base that isn't already there?

    You pay for: 1) incremental functionality and 2) somebody else takes care of packaging up that free thing into a useful form.

  9. Re:Google is evil on Alibaba Says Google Threatened Acer With Banishment From Android · · Score: 2

    That's an evil move of Microsoft proportions, for Google to threaten Acer like that. It's just like what Microsoft did to IBM over OS/2.

    Are we sure this actually happened? It seems rather unlikely that Googlers could be that stupid. Clearly an official response from Google is called for, sooner rather than later, and regardless of whether the report is accurate.

  10. Re:But the cost? on WD Builds High-Capacity, Helium-Filled HDDs · · Score: 3, Informative

    Is this going to be cheaper than SSD?

    Yes, of course. Only a tiny amount of helium is used.

    Also, are these going to be significantly faster than the standard five platter density drives?

    As usual for density increases, transfer rate goes up, seek time is unchanged. Moving disks even further into the role formerly occupied by tape. Maybe the reduced friction (= less heat) could make 10K drives more practical, improving seek time but probably also being a boutique product squeezed between SSD and 72k disks, and thus expensive.

    I'm guessing that this codec fails simply because Apple didn't write it and will, therefore, refuse to support it.

    The heralded death of the notebook was a bit premature apparently.

    It's not very far away. I don't normally even bother to take a laptop with me now when I travel, just a tablet and bluetooth keyboard. Lately, a bluetooth mouse as well which works nearly perfectly (some tablet apps wrongly assume that scrolling will only ever be via the touch screen). Of course there are some things the laptop can do that the tablet can't (yet) but this is more than made up for by the fact that the whole thing weighs half as much and runs on batteries three times as long.

    Tablets make a great spoon and terrible kitchen tool. They're good for consuming, but not much else.

    Not true. My Xoom has proved to be an excellent communication device: audio, video (Google Talk) and with a bluetooth keyboard, text chat. The only thing holding it back for editing is software. That will change as soon as LibreOffice comes out. The tablet also makes a perfectly usable terminal for remote administration work, which I have done often. Ssh is well supported.

    Remember, the IBM PC was originally intended to be a toy to compete with the Apple II. Transforming it into something useful was purely a matter of software.

  21. Re:Trading's Too Fast When It Ceases to Mean Anyth on More Warnings About High-Frequency Trading · · Score: 1

    You confused yourself by talking about "price" instead of "bid" and "ask". Presumably when you say "price" you must have meant "ask" because raising your bid over their ask must surely result in a trade. But raising your ask over their ask will just as surely not result in a trade (because if there is any trade it will be at the lower ask). So there is no recursion.

    Indeed, spikes to appear in price histories with no apparent explanation. But the cause is not nearly so simplistic as you imagine. And these don't require high frequency trading, another word is "bubble". With high frequency trading, bubbles just build and pop faster. And they are rare. The normal behavior of a high frequency market is a random walk just like a traditional turtle market. The main difference is, the spreads are tighter. It's hard to see why that is bad.
