  1. Re:not the problem on Micron and Intel Announce 3D NAND Flash Co-Development To Push SSDs Past 10TB · · Score: 1

    LBAs written are in sectors (512 bytes), so about 37B sectors or 19 TB. The Flash has written (actually erased) about 136TB, so you are running with a wear amplification of about 7:1. If the drive is full, this is not too surprising. The way to get Flash to last longer is to leave free space so that the FTL has room to work in.

    Nailed it. This drive is being tortured. 19 TB in one month is 630 GB (almost 2/3 of full drive capacity) written per day, or 7 MBps averaged 24x7, on a budget drive.

    Over-provisioning at the outset would have helped a lot, but that is still a hell of a big data load.

    Mortars have pretty poor accuracy as well. As well, they are not line-of-sight, so you have to have knowledge of the exact range and a good characterization of the ballistic performance of the mortar; then you have to dial in the correct elevation.

    Thanks for the tip. I'll check it out. The proper URL is http://www.freshports.org/sysutils/healthd/. Unfortunately all the links at that page are now dead and "there is no maintainer for this port". I will try it, with trepidation, though all other sensors related ports for FreeBSD appear to be garbage.

    I built a FreeBSD 10.1 server with a single root ZFS pool consisting of seven 3 TB drives in RAID-Z3, including a small 7-way mirror of swap space. The process was completely pushbutton using the install UI. Partly I did it just to explore how much difficulty the install might be (no difficulty whatsoever), but the setup has proved very effective in use.

    It was pretty cool rerouting some of the SATA connections randomly (even to a different HBA) as a test, and removing two of the drives as a test, and having it still boot to a fully operating state and run fully usably with no intervention or drama at all.

    After extensive experimentation and production use, the only real criticism I have that is just head-scratchingly stupid and lame is that there is no sensor capability, and no one in development seems to think there is a glaring problem with its omission. Coretemp works beautifully, but you can't detect fan rotation or access any voltage or secondary temperature sensors.

    Nonsense. The US dropped the world's first atomic bomb on Hiroshima, a military base [accuracy.org]. That was because they wished in this first attack to avoid, insofar as possible, the killing of civilians.

    Oh, bullshit. Hiroshima was no more a "military base" than were any number of American cities.

    A total of some 40,000 military personnel were present in the city. The rest of the approximately 350,000 population were civilians.

    The number killed was very approximately 100,000. It is plain that not even the majority could possibly have been military personnel.

    Why is it people who make comments like this never realize those in government are even more greedy? Income tax rate in CA on top incomes is over 50%, but the guy paying it is the greedy one. lol

    Sorry, but that won't wash with most thinking people. They realize that the taxes government raises are not to aggrandize the government, but to pay for programs intended to benefit people. The issue of whether many people IN government get unreasonably rich while performing their service is one which is completely separate from the issue of taxes.

    Self-aggrandizement is a natural human tendency. One can try to limit it using social policy, or one can just let it run wild. I would say present policy, though it does aid the poor, hammers the middle class, and does next to nothing to inconvenience rich assholes in any way.

    Nuclear has by far the lowest [environmental impact], but for the same reason that many environmentalists are still opposing the Keystone pipeline despite the reality of more incidents of environmental damage from the alternative (inefficient rail shipping with nearly 100x the rate of environmental exposure), it's all about emotion for many in the movement, not about what's truly, measurably better for the planet.

    Yes, the total economic loss due to the Fukushima nuclear disaster, estimated at $240-500 billion, is nothing but emotion.

    I never understood the sophistry involved in the quest for a "humane" execution. You are depriving someone of their LIFE. How humane can that be?

    OK, I can hear you guys before the chorus starts. "But, but, suffering!" I'm not sure why that bothers certain people so much in this particular context, but rather than going down a long path of logic against deaf ears, I'm perfectly willing to concede it. There are methods that are guaranteed to involve no physical suffering or discomfort whatsoever. Inhalation of 99.995% helium or nitrogen is one. A fully encirling explosive helmet would be another. Just a hand grenade under the chin is pretty goddam instant and sure.

    I'll give you another one. You know all those amps in a electric chair? Skull sizzling; eyes popping out; convulsions? It's utterly pointless horseshit. You don't need that. Two tiny needles with a local anesthetic, insertied to touch the heart, with an AC current of literally microamps will cause instant fibrillation and consciousness will be lost in a few seconds with no drama whatsoever. Lights out, baby.

    The death penalty should only be used when there is absolutely no doubt of guilt.

    It's a coward's way out, and I'll tell you why. Guilt is never 100% certain. I mean that literally. NEVER. Not ever. Eyewitnesses can be deceived or malicious. DNA tests can be in error (that has happened). There are situations where the probability of guilt is very, very high. Close to 100%. So close that the uncertainty approaches zero. But it will never BE zero.

    This is why the concept of "beyond a reasonable doubt" evolved. It is a high standard, but there is no metric. It is by definition a judgement. If "beyond a reasonable doubt" isn't good enough, the only honorable decision is that you don't favor capital punishment, period, end of story.

    I can respect both the viewpoint favoring capital punishment for heinous crimes, and the viewpoint that capital punishment is NEVER justified. But I could never respect the concept of "capital punishment, but only when guilt is magically certain". It is a dodge.
