    However, you will have burnt off calories that you otherwise would not have needed to ingest in the first place.

    Along the way from solar energy to your feet, a lot of energy is lost. For example, aots are only 1% effective at converting sunlight for use in growing. And that's not even counting all of the farming going on, transportation, packaging, making the stuff into oatmeal etc. etc.

    Here is an interesting link.

    In case you can't figure out the energy efficiency, just enter something like 76 kcal / 4600 btu in google. It works out to a measly 6%. Imagine the savings if you used a car (running on hydrogen, perhaps) that was powered by solar energy somewhere down the line.

    And that's for a vegetarian breakfast!

    While there's nothing groundbreaking about the 'inventions' themselves, the fact that he has persisted with his tinkering in the midst of an Arab culture speaks of incredible curiosity, freethinking, and persistence.

    WTF? Exactly how does "an Arab culture" impede invention? There's a lack of research spending in most of the Arab world, granted, and there's a lot of illiteracy (keeping the people stupid makes ruling over them a lot easier) but nowhere in the Quran does it say "thou shalt not tinker", I'm sure.

    Just because the Taleban were notoriously down on music doesn't mean even they were anti-technology. Anti dependence on the West for technology, perhaps. Anti-satellite television, most assuredly. But an anti-technology mindset isn't something you can claim for some of the earliest adopters of heat seeking handheld surface-to-air missiles.

    And even all of that has precious little to do with the Taleban being Arabs, than with them just being a bunch of nut jobs.

    In fact, the fact that most of the people in the Arab world are pretty poor, probably means they're a lot more inventive on a day-to-day basis than you or I, just because they need to be. They can hardly run down to Best Buy to replace broken stuff or to buy high-end alarm systems and the like. Expect the same to go on everywhere where the economy is pretty crappy for the average Joe.

    Now, getting engaged in politics in certain countries in the Arab world (for example, US big buddies Saudi Arabia, the country that brought you Bin Laden before he got US funds to become mujahedin in Afghanistan *cough*) is most definately discouraged.

    Well, my power supply is 230V, AC and, IIRC up to 16 amps. (20 and 25 amps are also common values).

    Perhaps you mean the Safety Extra Low Voltage norm (Low Voltage is anything between 50-1000V AC and 75-1500V DC).

    SELV specifies that the maximum potential difference between anything you can contact on a device, or anything on the device and ground, must not exceed 42.4 V peak, or 60V DC.

    Devices conforming to SELV don't need to be grounded, nor do they need special insulation.

    Having done a little digging on my own (google can be your friend, but a dictionary can be even better) it appears that "some guy on slashdot" got it right, while the various dictionaries you quote in fact copied not only each other's mistakes, but the mistakes as they have propogated into common parlence. As to the 'chicken-or-egg' question of whether the misuse first began among the semi-literate masses, or was spoon-fed to them by the semi-literate media and/or erroneous reference compendia, can only be left to speculation.


    Dictionaries should report on what a term means in common parlance. They're to be used to look up utteranced from common parlance, so you can understand what the language user was on about. If the dictionary said "100%", even though people overwhelmingly mean "the greater part", you could get quite confused, especially if English was not your first language.

    Dictionaries that list the original meaning, or rather, the evolution of words and their meanings also exist. Those are called etymological dictionaries. There are also dictionaries that list jargon, specialized technical terms, business dictionaries, etc.

    To say which meaning of a word is the correct one is entirely dependent on who you're going to be communication that word to. The point is to bring the messages across, after all.

    Nokia expects to "launch" 35 new models this year. Thirty-five! And that's down from a projection of 40. Launching them 5 at a time as Nokia does, that means that their "product cycle" is less than 2 months.. And I still happen across shops that happen to have the phone I owned 5 year ago sitting quietly on the shelf, still unused in its original wrappings.

    And they all do the same job. Whilst there's no shortage of potentially substantial features to be added, you can count the number of phones that support for example 3G on the fingers of 1 hand. The rest send text-messages, dial and play a game or two.

    In truth, nobody needs all those new features. Bluetooth is very handy, and GPRS is nice for data (until 3G comes along), but you can already get all of that in last year's boring businessman-model.

    These new models are all basically the same, or rather, based on only a few underlying hardware platforms. Obviously the N-Gage is different from your average teenager's phone or a smartphone, but within each type the variation is both endless and pitifully trivial.

    Motorola was a master at this, they even kept older models in production by placing the new hardware with dumbed-down software in the older shell, adding a weight to keep the handset weighing as much as the old model(!).

    The same is of course true of Digital Cameras. Each new model only replaces the CCD with a few more megapixels, or adds some software feature, perhaps changes the shell to something less plasticcy looking. The Olympus range is a good example. Or IIRC the Canon 10D which can be made to do almost all of the 1D's tricks, except take more pictures per second (due to RAM speed/amount apparently).

But actually, there is no end to the number of relative newbies who can't get their heads around the task, especially when it comes to threading. Which I suppose is the reason you see so many PHP forums that don't have threading, unlike our beloved slashdot that even indents messages correctly.

    These people are completely befuddled that their database of choice (usually MySQL) can't do recursive queries, so if every post contains a pointer to its parentpost, it's pretty expensive to thread it.

    This is something most people never think about. You actually could have several passwds that work for a given account...anything that hashes to the same thing is a working passwd.

    Another neat example of this principle at work is the soundex hash function, which was designed for the US Census to lookup names. It encodes a name such as Johnson as an alphanumerical code J525. Other, similar names, such as Jonsson, Joganson and even Jamieson and Jenkins are converted to J525 as well. In this way, even if people's names are misspelled in some way in the census (or when they were registered at birth; family names tend to evolve over time) they can still be found by a reasonable approximation.

    And because the soundex hash is computed when the records are stored, there isn't the kind of overhead that you'd get from a regular expression/glob search over all the records.

    The modest computational requirements for what amounts to a very clever phonetic lookup mechanish aren't surprising in a way; Soundex was patented in 1918.

    You can play with soundex on this page.

    Now imagine your password was stored as a soundex hash.. Ouch! Even if someone looking over your shoulder when you type in your password got half the letters wrong, he'd still get in!
