    i think both of Google's founders were smart enough to understand they were GEEKS and not try to run the business themselves. So they went out and got Eric Schmidt

    TFA explains that Page was not very cooperative to get a mature CEO. Essentially, he had Schmidt shoved through his throat:

    Page had never been behind hiring [Schmidt] -- or any CEO, for that matter. Google's investors made him do it. (...) And for a long time, Larry Page was very unhappy.

Not something I want in my kitchen. On the other hand, all synthetic counter tops, including granite-look composites, are not guaranteed to handle hot pans. I ended up not buying a new kitchen...

  6. Re:13 deaths? on Department of Transportation Makes Rear View Cameras Mandatory · · Score: 2

    Cars would probably be a lot safer if they were made more simply, and they didn't change the design ever 2 or 3 years. Stick with time tested designs and get all the bugs out and you'd end up with a car that was reliable and safe.

    That is a strong assertion. Can you back that up? Over the years, cars have become safer both for the people inside and other road users (well, the latter probably doesn't really hold for SUV monsters), and also got much better fuel economy. A lot of that you can't achieve by debugging an existing design. Think of aerodynamics and crumple zones, which are integrated into the entire car design. Over here (Netherlands), the minimum age and frequency for mandatory technical inspections of old cars have been relaxed over the years, apparently because of the increase in durability.

    I did once peek over the shoulders of a guy servicing one of those in-store ATMs (i.e., one that looks like a stand-alpne cabinet, not one that's integrated into a wall). Apparently, it's not all that tightly locked down, hardware-wise. The guy told me that only the compartment that contains the banknotes and the counting mechanism have heavy physical security, and that he couldn't access that part. That was why he was allowed to service the machine by himself, in the middle of a busy store.

    "you can only extract 20% of their capacity from them before you damage the battery by sulfating the plates."

    You're confusing two issues, I think. Sulfation happens if a lead acid battery is kept in a (partially) discharged state for too long (weeks). That will happen with deep-cycle batteries as well.

    The issue with starter batteries is that the plates are thin and tend to crumble during a deep discharge, when a large fraction of the lead plate is electrochemically converted.

    The radio transmitter in a cellphone is about one watt. For battery lifetime, you really don't want the transmitter to activate every few seconds.

    "WIth a VM you have to install, maintain, patch and monitor everything yourself"

    My experience with shared hosting is that they change system configuration all the time without informing me and thereby breaking my scripts. Never have that problem with a VM, but I admit that setting up a VM with dns, apache tweaks, iptables, and so on, is a major effort for someone who doesn't do that for a living, like me. But after that it's very little maintenance.

    By the way, the site in my sig runs on shared hosting, including perl CGI and ssh, for EUR 7.95/yr. Cheaper than my time in figuring out how to setup multi-domain email in CentOS on my VM. But I had to tweak my scripts to deal with the peculiarities of this hoster and live error logs only available via directadmin...

    the NYC law I wonder how it'd handle an electric bicycle that uses some sort of strain sensor to decide how much 'assist' to give the rider. IE you could set it to 100% and it'd try to match the power the user is putting into the bike

    Well, it says: "motor that is capable of propelling the device without human power", so that should be legal. Here in the Netherlands, e-bikes have such a strain sensor; I think it measures strain near the back-wheel axis. And it is for legal reasons -- otherwise they would count as a moped and need a license plate and liability insurance.

    By the way, e-bikes are getting rather popular in Netherlands, despite our lack of hills and bike-friendly temperatures. Still feels weird to be taken over at a considerable speed difference by an old lady sitting upright catching wind, with bags of groceries.

    You would think that cinema speakers ... would be impervious to damage but some movies occasionally overdrive the speakers to a point that the drivers are damaged. ... there was 7 seconds of high pitched buzzing on reel 4 that could destroy the speakers.

    A big difference is that those are speakers with separate woofers and tweeters. A typical audio signal has the vast majority of the acoustic signal in the low frequencies, so a loudspeaker capable of handling 100 W could have 90 W for the woofer and 10 W for the tweeter. If you send a maximum-amplitude high-pitched sound to the speaker, it will fry the voice coils in the tweeters. (I've had this happen when I tried to check whether I could hear up to 20 kHz from my loudspeakers ....)

    One could wonder why tweeters are not fused, though. Apparently this is not trivial.

    Anyway, laptop speakers are most likely a single driver for the whole frequency range, so tweeter overloading is not an issue.

    "Things like fever and coughing are part of the body's immune response,"

    But not necessarily effective ones. If your lungs are irritated, you cough, whether or not there is something that needs to be expelled. Worse, extensive coughing can cause irritation, which leads to even more coughing.

    If you are coughing up mucus, take an expectorant to decrease the viscosity of said mucus (e.g. bromhexine, acetylcysteine) and make the coughing more effective.

    If it's a nonproductive dry cough, you should don't hesitate to take an anti-tussitive (cough suppressant), e.g. codeine, noscapine, dextromethorfan.

    There's also a theory that common cold symptoms are an allergic reaction that's best suppressed with 1st-generation antihistamines. At least, runny nose and coughing don't expel the virus which is multiplying IN YOUR BODY CELLS.

    I find it rather unbelievable that this is possible in general for any smartphone. Indeed, the site of your first link writes:

    many Android Gingerbread, Honeycomb (and, of course, Ice Cream Sandwich) devices are on the long list of products unsupported by the software.

    The extraction process would be similar to rooting an Android phone. Online, you'll find many rooting HOWTOs which may give a hint to how easy it would be. On some phones, you just have to place a zip file with the appropriate /system/xbin/su binary on the SD card, and boot the phone in recovery mode. (For sluuurping, one would of course put a system binary in the zip file that would dump the entire system onto the USB cable).

    For otther phones rooting requires that USB debugging is enabled (not the case with most people) or that the bootloader is unlocked - which may result in a factory reset that wipes (or just deletes?) existing user data.
