    Does the shape of the food really matter? I think the texture is a far bigger deal.

    Sometimes, yes. I considered building one of these myself; I believe the reprap design is able to print in sugar paste and/or chocolate, which could be useful for cake decoration. Note that people pay serious money for customised wedding cakes.

    There is no dark side of the moon, really. Matter of fact, it's all dark.

  3. Re:Always wondered where these came from... on Russian Payment Processor Runs Massive Scareware Operation · · Score: 1

    I recently ridded my wife's computer of such a virus/trojan, whatever -- this day, we can't figure out how the machine ended up with it -- maybe autorun off a usb stick?

    The last one I got was injected via a (apparently 0-day) vulnerability in the Adobe Acrobat plugin that was exploited by banner ad code that was hosted on thepiratebay.org. The previous one was similar, but used a Java flaw. These were both browser neutral exploits, although I happened to be running Firefox. I have since installed Noscript, which appears to be the only way to guarantee security these days. I've also recently seen something similar on a friends' computer that was smart enough to completely hide the traces of where it came from, although I also suspect a banner-ad injected exploit in that case. I'd suggest anyone browsing sites that use the kind of dubious ad banner networks that show up adverts for "facebook of sex" or similar dodgy sites install it now.

  5. Re:Current Multi-Monitor Gaming is Complete Crap on Budget Triple-Screen Gaming · · Score: 1

    Multi-monitor gaming is pointless, and will remain pointless, until video cards can render separate views, or a single view with cylindrical or spherical projection

    The cards are perfectly capable of rendering this, iff the game tells them to do so. That most game developers have not seen fit to include such options is hardly the card manufacturers' faults...

    OTOH the fact that DirectX can only render to a single device at a time and my two monitors present as separate devices with no option to switch them to being a single device on the fly does appear to be partially NVidia's fault.

  6. Re:To be "fair", start with a 5-10MB disk on Upgrading From Windows 1.0 To Windows 7 · · Score: 1

    If you want to be fair, you should start with a 5-10MB disk, which is what was available around the time of Windows 1.0/DOS 5.

    My first machine was built in 88 (after the release of Windows 2.0, but before it became popular -- the hardware requirements were considered too high at first, I believe) and supplied with Windows 1.0, DOS 4.01, and a 45MB HDD. It was a common configuration at the time, I believe. This chart suggests the 5MB disk was history by the time Windows 1.0 was released in mid 85, and that 10MB was history by the time Windows 2 was released in late 87. By the time DOS 5 was released in 91, 100MB would have been the most common disk size.

    I consider the use of DOS 5 a cheat. Nobody would ever have installed Windows 1 over DOS 5; they were not contemporary. At a guess, the only reason DOS 5 is used is that it supports 2GB partitions, which DOS 3.1 (the appropriate contemporary for Windows 1) couldn't do, being limited to 32MB. So the process should start with DOS3.1 and a 32MB disk and progress from there, IMO.

  7. Re:trim/discard on SSDs Cause Crisis For Digital Forensics · · Score: 1

    Maybe it's still there if you look with a microscope but who really does that?

    The forensics team mentioned in TFS?

    Most of the time, they don't bother. Disassembling your SSD and mounting it to be examined in an electron microscope is an expensive, time-consuming process. I don't know how much it would cost, but I know the equivalent operation for a hard disk is actually so expensive and unreliable that police forces effectively never use it: there are no guarantees of results, and with modern disks being so large the chance of finding enough of a (probably quite small) chunk of incriminating data to be useful is very low. AIUI no documented examples of such a technique having been performed in the real world actually exist (at least more recently than the 1980s, when disks were smaller, gaps between cylinders much larger, and the data you're looking for much more likely to be unencrypted plain text). I also believe that recovery of overwritten data in flash memory is more expensive and probably even less reliable.

  8. Re:Why can't they make up their minds on SSDs Cause Crisis For Digital Forensics · · Score: 1

    But what happens if you use a different file system the drive makers didn't think of? Do you risk losing data because the SSD misinterprets your file system structures?

    I would assume they're checking FS magic numbers (e.g. "NTFS\x20\x20\x20\x20" at offsets 3-10 of the first sector) before doing anything interesting, which ought to make it safe as long as you're not doing something totally bizarre. This doesn't mean your ext3 system can't take advantage of it, of course -- just write a blank NTFS system over your fs and reboot.

    Not necessarily. Access to Android Market is restricted to official OS builds. A lot of the cheap device manufacturers in China are shipping devices that run unofficial builds and are not able to access the official market. Users of these devices are just doing the only thing they can by using alternative app stores.

    The senator is arguing against a straw man version of the legislation. CFL and LED are not the only alternatives to traditional incandescent lighting; low poer incandescents and halogen lamps both conform to the requirements of the legislation as well, and both are much harder to argue against than CFLs and LEDs.

    On the other hand my condensing nat gas furnace is 95-99% efficient.

    Yes, but it also (1) requires a supply of natural gas to your property, which is a dangerous gas that is regularly the cause of fatal accidents (either directly due to explosion or indirectly due to CO produced during combustion) and (2) cannot be powered from renewable sources.

    Harder to manufacture doesn't matter - you aren't putting them together personally so why do you care.

    Because lifetime efficiency is relevant, and hard to manufcature typically equates to (1) more energy being used in the manufacturing process and (2) the items being manufactured in a single central location and shipped all over the world rather than being manufactured locally.

    Maybe you get 100% efficiency in the winter, by using an incandescent, but in the summer the incandescent bulb is working against your air conditioner.

    This may be news to you, but not all of us live in climates where air conditioning is a necessity. FWIW, I use heating around 10 months of the year, and only struggle to keep my house cool enough for about 2-3 weeks of peak summer. Your argument simply doesn't apply to me.

    Point 1 is that FTL is looking possible but hard. There are valid solutions to general relativity where Star-Trek like FTL happens.

    The validity of these solutions is somewhat disputable; they all require the use of some as-yet-unknown material that has negative mass. As no such material is even theorized to exist, to suggest these solutions are valid seems to be jumping the gun somewhat. All we can say is that general relativity by itself doesn't rule out FTL travel.

    Not to mention this whole "habitable zone" thing is a load of crap IMHO. I mean what are the odds that some alien race is gonna come out just like us and therefor need the exact same conditions as us?

    Habitable zone === possibility of liquid water on open surface. This is much broader than the exact same conditions we require, and as we've had theorists thinking for a long time about possible life chemistries that are different from our own, and most still think that water-based life is the most likely to occur, it seems a reasonable starting point.

    We have already detected the possibility of liquid water on Europa IIRC, and that is pretty damned far from the "habitable zone" so who is to say there aren't plenty of creatures living on worlds farther out?

    Europa is a pretty unusual situation. It also has a few serious disadvantages that may make it less likely that life would occur on it than a typical "habitable zone" rocky planet, some of which are likely to happen anywhere a similar feature occurs. The biggest is that it's quite small, which reduces the likelihood of a life-starting reaction occuring there. It's energy-starved in comparison to a planet with a warm surface, which also makes the likelihood of a life-starting reaction lower. Both of these issues are likely to apply to Europa-like moons in other star systems.

    No, it doesn't. OTOH, most android tabs I see on the market have numerous actually-useful features that the iPad lacks. They almost universally have USB connectivity, meaning you can hook up a large selection of expansion devices to them. Most have HDMI video output, allowing them to be used as an HD media players. Almost all have MicroSD slots, allowing you to expand their storage and exchange data more easily. Several have dual-core ARM Cortex A9 cpus (typically based on the NVidia Tegra) that make the tablets substantially faster than an iPad which is only a single core A8.

    Agreed. Latest figures I can find (Q3 2010) put Nokia's worldwide share at 28.2%, with their largest competitor being Samsung at 17.2%. Yes, this gap is definitely down on previous years, but they're still the market leader and anything could happen in the future. Even if we consider only smartphones, Symbian is still the leader (36.6%) with Android lagging quite a way behind (25.5%).

    Yes, Nokia's in decline. But that's a long way from being "toast". And it's Android and the various cheap-brand non smartphones that are gaining, not Windows Mobile (which actually saw a significant drop in market share in 2010).

    The question is whether it interferes with the employee's ability to do their job. An employee making snide comments about their employer doesn't necessarily do that (unless the employee works in PR, for example); OTOH a teacher making demeaning remarks about their students that then get back to those students *and their classmates* is very likely to interfere with the job of educating those students. It's hard to take a teacher seriously who resorts to calling you names behind your back.
