    Can't he concentrate on being a better person *by* being a better programmer? Or at least *while* being a better programmer? The idea that coding is merely some tedious task with no benefit for the coder or the world is a very limiting view.

  3. Re:The measurements in question: on Data Center Study Reveals Top 5 SMART Stats That Correlate To Drive Failures · · Score: 1

    You can't compare real filesystems to EXT. EXT4 is a backport of some of what is possible in modern filesystems to a brand name that makes people comfortable. Like most filesystems it's sufficient for many uses, but it's not particularly good at anything and it's really bad a whole slew of fairly common uses. It's not even a good compromise for backwards compatibility, like EXT3 was, as volumes formatted as EXT4 can't be mounted as EXT2/3.

    I'm not saying EXT4 is bad, just that it isn't a terribly useful baseline for comparison. By the time you get to systematically evaluating a filesystem on functionality and performance EXT shouldn't even be on the list, except maybe to help people who don't understand the problem see why you want to make a change in the first place.

  4. He hasn't given up, he's just acknowledged the reality that the variance among drives of any particular model is large enough that he can't statistically pick a winner even given reliable statistics about the past performance of similar drives (which is definitely not available) and assuming the drives never change over their manufacturing life (with is definitely not true).

    If you're buying 1000 hard drives their average reliability is meaningful to you (though even then it's only *a* factor, not *the* factor). But if you're only buying a handful of drives and prioritizing reliability you're much better off with diversity than any single model because the average reliability means almost nothing in your small application and diversity at least lets you avoid duplicating systematic faults.

    Whatever strategy you think you've devised to beat the statistics is just you hoping to pick the right stock/horse/number and lying to yourself about the odds -- even if you have good data and choose the statistically best option there's still a very good chance it won't turn out to be the best one available and a moderate chance it will be one of the worst.

    GPS can be cryptographically authenticated, at least for authorized users. You can jam it, but you can't easily fake it, at least not against receivers that are worried about such things.

    Another way to look at it: Non-radio navigation continues to be possible, and constitutes a practical, cheap, already-in-use backup to GPS for most ship-related uses.

    LORAN is fine and has valid uses. But it also has a cost, and taking it down doesn't meant that ships will get lost or crash into each should GPS become unavailable.

    The system can be selectively disabled to prevent use in specific geographic areas. Those areas are fairly large but not global.

    And if the decision was made to disable GPS in the US they would most assuredly turn off any local radionavigation system as well.

    Do these schools of thought know that the chip is inside a piece of glass? Are they suggesting that glass causes cancer? They can't possibly be thinking of effects related to the radio emissions, as the chip has no local power source -- it is only active when powered by a fairly strong emitter and most pets spend well less than 0.0001% of their time in such a situation even if their chip is read many times each year.

    What is it about a server that makes systemd inappropriate? NetworkManager I see; servers rarely change their network configuration when they do they want to do it in a controlled way, not an automatic way.

    If one of your required qualifications is "be part of an existing program that old admits men" then the program is sexist merely by its requirements, even if those requirements are applied equally to all candidates. Neither does discrimination require malice or intent -- unintentional discrimination has exactly the same outcomes as intentional discrimination.

    You also can't claim both that there were no women up-to-snuff therefore no discrimination existed, and also that selecting women would have imposed an additional burden on NASA. One of those scenarios claims there was no discrimination while the other one claims that discrimination was present and intentional but justified. And again, if you construct one of the requirements to be "must urinate via a penis" it doesn't matter that you apply that standard to everyone who applies, it's still sexist (and assumes that "male" is the default option and the females have "extra" requirements -- even if gender was a legitimate reason to discriminate, why are females the group selected against instead of males?).

    But mostly this is absurd, because if NASA wasn't discriminating against females they would have been in the extreme minority of organizations at the time. Sexism was even more ridiculous then than it is now and to presume that NASA is or was somehow exempt from that culture-wide phenomenon just because they dreamed up an arbitrary set of performance standards is insane.

    Some people -- particularly those with 2 servers -- transfer data on paths other then WiFi endpoint Internet. Wired Ethernet is definitely faster in such cases. It's also frequently more reliable, easier to secure, allows simultaneous full-speed transfers, is full-duplex, doesn't incur a repeater penalty for transfer among local endpoints, requires less configuration and frequently avoids the need for custom driver installation.

    Not that there's anything wrong with WiFi. It has lots of useful applications, its own set of benefits, and is definitely sufficient or even preferable for many installations. But to suggest that there's no use for wired Ethernet in a tech-heavy home scenario is ludicrous.

    Exactly what makes parents more qualified to make educational decisions than other people? I know they *feel* more qualified, but it's unclear to me that feeling is justified by any observable fact. Parents have a certain perspective to offer, but no particular expertise (at least not as a group), and certainly not the only valid perspective. What you're suggesting is essentially self-regulation -- which we know from other areas creates inherent conflicts of interest and readily ignores broader societal goals. Why do you think it will work here when it clearly does not in other places?

  22. Re: Misleading Headline on Protesters Blockade Microsoft's Seattle Headquarters Over Tax Breaks · · Score: 2

    And the parent says "fair" as though there's only one way to evaluate that declaration. As with most things it's a more subtle question than simply declaring that some other position is morally wrong and therefore your position must by default be the only acceptable option. If you want to support a regressive tax feel free, but simply declaring that a progressive tax isn't clearly morally superior is not the same as providing rational in support of a regressive tax.

    Moreover anyone who excludes payroll taxes from their definition of "income tax" is stretching credulity. Payroll taxes are paid by even the very poorest earners, are proportional to income, and are deducted from paychecks. The only people who avoid them are the very rich who either hit the upper limit -- though it's unclear why such a limit even exists -- or those who don't have earned income in the first place, like those living on investment income.

    And of course most poor people pay both payroll taxes and sales taxes, even if they "pay no income taxes at all". Which is why taxation needs to be considered as a system and not as a series of independent pieces -- only they very rich have the freedom to choose which taxes apply to them.
