  1. Re:Greenspun's Tenth Rule on Taking the Pain Out of Debugging With Live Programming · · Score: 5, Insightful

    I suspect you haven't seen a Common LISP debugging environment. Yes, they allow breakpoints, as well as live code modification. (And if you were lucky enough to have a LISP machine, you could dive into the code behind your libraries, your operating system, etc. -- updating state on the fly, all the way back to tweaking a driver on a running machine... on the fly, in LISP).

    What we have these days (say, Clojure's nrepl) isn't as powerful as that, but it's pretty damned powerful even so. Want to tie into your production system and see what a new version of a function would do against currently live production data, without actually changing the production system's behavior? If you're writing purely functional code, you can do that trivially... and the language strongly encourages pure functional code (as opposed to many "modern" languages where trying to write things to be side-effect-free is working against the grain).

    If the best example you can think of is QBasic, you have no idea what a REPL can do.

    Once we're on the right-hand side of the Laffer curve, you'll have room to talk. Until then, you're just being (knowingly?) disingenuous. Every serious study puts us to the left -- often, far to the left -- of the peak.

  3. Re:So.... on Largest DDoS In History Reaches 300 Billion Bits Per Second · · Score: 1

    Spamhaus must be costing somebody (or some people) a LOT of money to draw such a massive attack.

    They're using DNS amplification -- so that money is mostly being paid by folks running misconfigured DNS servers.

  4. Re:you're out of touch with non-city life on Washington's Exploding Manholes Explained? · · Score: 1

    You don't want to drive to pick up groceries. OK, so how do you get them home? Horse? Somebody else drives? You just don't, because you eat out all the time?

    Bicycle (folder, so it comes in the store with me -- no need to lock up outside). Or at least, that was how I picked up groceries for my urban household before moving to a block away from a market; now, I just walk next door.

    Bigger picture, though: If you're looking at infrastructure investment and maintenance, high-density living (with mixed-use zoning) is far more cost-effective on a per-person basis. Maintaining utilities (and especially roads) has a huge cost per mile; put more people in less space, and put their entertainment, livelihoods and necessities near them (with transit to cover the cases that walking and biking don't reach), and you're waaay ahead in a city -- able to provide better services to more people at a lower cost.

  5. Re:Force stopping 'Running Apps' from 'Switch Apps on Ask Slashdot: Getting Apps To Use Phones' Full Power? · · Score: 2

    It lives on only as a cached process, not as a live one. Those are reaped whenever anything else would use the resources they're using -- it's not _truly_ stopped, but it's a functional equivalent for all reasons that matter (unless it's your intent that your application lose all its state -- this can be useful if you're trying to clear a bug, for instance, but will have no effect on performance on the rest of the phone).

    ....and of which none of the competitors do as good of a job as VMware. I guess you get what you pay for.

    I wish you did -- then VMware ESX's SCSI emulation would actually be up to par with what's in qemu/kvm. Sure, they implement the mandatory mode pages, but you want anything unusual? Good luck.

    There's nothing out there that's so vitally important, yet incredibly rare on Earth, that makes it worth it.

    If you think "rare on earth" is in any way part of the point, you aren't paying any attention. People proposing mining asteroids aren't proposing returning the materials they mine to Earth.

    To amend my prior answer with an actual reference -- see http://www.phrases.org.uk/meanings/beg-the-question.html

    On the subject of the reliability of said source:

    While no reference work is able to claim its content is 100% definitive, every effort has been made to include here only information that is verifiable as correct. The content is researched to published book standards. The sources used in the research are twofold, either primary sources or trusted references. The primary sources include newspaper cuttings, books, films, photographic archives etc. The trusted reference sources are those that themselves derive from primary sources and have sufficient reputation to be considered reliable. These include, The Oxford English Dictionary, Second Edition, The Historial Dictionary of American Slang, First Edition, The Oxford Dictionary of Quotations, 5th Edition, Partridge's A Dictionary of Slang, 8th Edition. In addition to these are numerous reference works and databases which, although not in themselves definitive, provide a rich source of stimulation; for example, Cotgrave's A Dictionarie of the French and English Tongues, Hotten's Slang Dictionary and many others.

    "Beg" is just (in the context of questions) an old-fashioned word for 'ask'.

    "Beg the question" is shorthand for "beggar the question" -- to make it worthless by depriving it of its value (as, in this context, it is provided with an answer ready-made).

  11. Re:I love working with PV cells on Bosch Finds Solar Business Unprofitable, Exits · · Score: 0

    When did profitability as a consumer and profitability as a producer have anything in the world to do with each other, particularly when the producer in question is a 1st-world company with a very good (and expensive) engineering staff that could be on projects where they're not dealing with heavy Chinese competition?

    (I'd love to see Bosch build a version of their mid-drive e-bike motor for export to the US market; they're quite popular in Europe, but underpowered compared to what's legal here. I've yet to hear of a Chinese mid-drive ebike motor that wasn't crap; the only US importer I know of that carried them, R Martin, recently discontinued that line, and the lone US manufacturer of mid-drive ebikes focuses only on the very, very high end of the market).

  12. Re:Imagining the possibilities on Google Reportedly Making a Smartwatch, Too · · Score: 1

    Can bone conduction work with a watch-like device? You could hear your phone ring without disturbing anyone else, and if you could identify the ringtone you could tell how important the call is.

    Bone conduction has a pretty short range -- you really want it to be something that's sitting on your head, not that far from your ears. Now, for Glass, it'd be absolutely perfect (as a way of providing audio without interfering with one's hearing when not playing anything back), but not much so for a watch. Anyhow -- just from a battery perspective, I'd want to keep the watch device as tiny as possible, basically just I/O for the big CPU on your phone; the Pebble strikes that balance perfectly. Adding sensors makes sense, to the extent that such can be done without compromising weight, size, and battery life.

  13. Re:Obama = Another Nobel Prize on CIA To Hand Over Drone Program To Pentagon? · · Score: 1

    As for the second war -- which was that? Afghanistan is still going

    To be fair, Obama was completely and totally transparent during the election process that he thought the war in Afghanistan was justified and proper, and that he thought the Iraq war was an unnecessary and harmful diversion from the place we needed to be. People who didn't listen closely, and just thought of him as an anti-war candidate, have only themselves to blame.

  14. Re:And why not ? on Jedi May Be Allowed To Perform Marriage Ceremonies In Scotland · · Score: 1

    Sorry? You claim that allowing a government official to make an arbitrary decision to refuse to marry two people who wish to enter into such a relationship would somehow promote the cause of personal liberties, when it's already established law that the only way that such a legal relationship can be entered is with the approval of that government agent? Silly me; I thought we cared about the freedoms of the public more than we cared about the "freedom" of government officials to throw their weight around in deciding how they carry out the duties associated with their positions.
