  1. Re:How parallel does a Word Processor need to be? on How We'll Program 1000 Cores - and Get Linus Ranting, Again · · Score: 1

    How much indexing and searching does Joe User do? And what percent is already done on a high-core-count server where parallel algorithms have already been implemented in the programs running on that kit?

    Indexing (sorting) and searching in my email client are right up there with games, engineering applications, compression/decompression, and error recovery in using 100% of 1 CPU core while not being I/O limited. Firefox is in that list as well.

    So most of the programs that I use which contribute to a slow experience on the user side do not take advantage of multiple cores. The exceptions are video transcoding and error recovery set generation which can use as many cores as I can provide which is currently up to 4.

  2. Re:Win/Lose on Writer: How My Mom Got Hacked · · Score: 1

    A new problem with memory which relies on floating gate storage which includes USB Flash drives and SSD Flash drives if it is used for archival storage is that the densest and cheapest Flash EPROM has an unpowered retention of months. I do not know how USB Flash drives handle it but SSDs perform scrubbing while powered so previously written data is not lost but their unpowered retention is considerably less than the life of a burned CD or DVD or a hard drive.

    If you're a 'suspect', and they want to talk to you, then at a minimum, you're forced to pay to retain counsel (unless you're stupid, and talk to them without one).

    Since law enforcement cannot be trusted, there is no reason to talk to them or answer their questions at all. The Miranda warning is literal; everything you say can and will be used against you however what is unsaid is that anything you say which would exonerate you is just hearsay and not admissible in court.

    Attribution in cyber is hard [lawfareblog.com], and the general public is never going to know the classified intelligence that went into making an attribution determination, and experts -- actual and self-appointed -- will make claims about what they think occurred.

    Is that all that classified evidence that Iraq was manufacturing weapons of mass destruction? The US Government is going to have to earn that kind of trust before they can be believed in anything.

    Where did I post anything to suggest what you're suggesting?

    And that [latency] actually gets worse rather than better when you increase the frequency

    Increasing the RAM frequency has little or no effect on latency; it only changes the unit of measurement. Latency as measured in clock cycles goes up but latency measured in nanoseconds stays roughly the same (actually it generally gets better) and it is the later which matters as far as the processor is concerned.

    The first word access time shown in this table is the most relevant:

    This is basically what I did long ago although I prefer stranded cable. One thing to watch out for is that the cheap plastic crimpers have a tenancy to crack leading to unreliable crimp connections. For about $50 you can get a much better crimper like a Greenlee 45553 which I have or Paladin Tools 1545 or 1387.

  8. Re:Many DDR3 modules? on Many DDR3 Modules Vulnerable To Bit Rot By a Simple Program · · Score: 1

    This used to be the problem back in the day before DDR3, true. After DD3 got to around 1333-1600MHz, the problem was effectively eliminated in favour of latency being the only reasonable bottleneck. And that actually gets worse rather than better when you increase the frequency

    The latency at higher clock frequency does not increase in the way you suggest. It only appears that way because latency is measured in clock cycles so when the clock cycle is halved, twice as many are needed for a given duration.

    Hold on just a second. There are many fine public defenders who happen to be far better than just "decent". They will not, however, be able to dedicate much time to your case. THAT is the issue with many PD's. Not that they suck or are not "decent" but that they are over worked.

    So why did this prosecution for war crimes never happen? The most charitable explanation I have been able to come up with is that Obama thought the unrest this would cause in the USA would be unacceptable, but I admit it is a weak explanation.

    Professional courtesy. Politicians, prosecutors, judges, and law enforcement officers generally do not turn on each other either.

    What happened just reminds me that neither party and none of the branches of government at any level can be trusted ever.

    If you actually read TFA, you'd see that it also indicates that Bush had little to no knowledge of the specifics of the interrogations or their brutality, and in 2006, upon his learning of it, it was ramped down.

    Either he knew or he should have known. In the later case, I am sure he arranged "not to know" for reasons of plausible dependability and it was ramped down when it became apparent that what was happened would be discovered.

    I consider this the swan song of the democrats who are taking a scorched earth policy in their forced retreat. Their leaders knew all about this when it was happening and said almost nothing to stop it. Then, when they where in power, allowed the administration to use the same techniques without so much as a peep, but are all so willing to take credit for killing OBL who's location was discovered though such techniques. It's just political posturing, and not much more.

    I blame both sides which are the same party anyway.

    The really sad part though is that it is highly possible that the release of this report will cost Americans their lives. The world is a dangerous place, but it's stupid to poke the enemy or hand them such a public relations win as this will be. We will be lectured by Iran and North Korea for human rights abuses and you can bet ISIS will be happy to use this to recruit/conscript more help.

    It is too bad that did not dissuade them from torturing people in the first place. We deserve what is going to happen because of this.

    But where do you start encrypting? You have to secure your PC against keyloggers and screen-grabbers even if your disk drive and communications are encrypted.

    But even opportunistic encryption would make interception much more costly. Right now it is next to free because everything is being sent over the equivalent of postcards for anybody to read. The evil doers also run the risk of being detected.

    And how would be sure that no man-in-the-middle intercept didn't have the processing power to crack the encryption?

    The same way you know now. If the authentication does not match, then a man-in-the-middle attack has occurred and if that does happen, then you have proof. Do you remember all of the court cases which were thrown out because the plaintiff lacked standing because they could not prove their communications were intercepted? Now they have an easier burden.
