  1. Idle on MacBook Pro Specs Leaked, iPad Event March 2 · · Score: 1

    Since the redesign there is no way for me to filter Idle.

    I thought I was alone in noticing. You used to be able to filter it in the old index, and I did. Some[who?] have speculated that they have deliberately made it hard to filter Idle because it helps to push traffic to other chosen sites. I noticed some submitters commenting in threads that their submissions' links have been changed from direct links to the content over to those annoying adword-infested blogs that so many complain about.

    I don't want to risk filtering a story about idle CPU time just because it has the word "idle" in it. And even when I do filter Idle, I still get Idle stories showing up. It doesn't work.

    I triaged the problem differently than you did: I decided that I loathe Idle enough that I am willing to lose ham in order to kill more of the spam. Of course, as you pointed out, it doesn't work if they studiously avoid using the word "Idle" in the submission.

    After the redesign, many options simply don't work.

  2. Abrogation of ACID? on WI Capitol Blocks Pro-Union Web Site · · Score: 1

    I have noticed this as well. I chalked it up to a possible abandonment by Slashdot of ACID principles over to the antithesis, namely BASE "(Basically Available, Soft state, Eventual consistency)".

I would really have to be painted into a corner in terms of scalability to relax ACID in favor of a BASE approach to anything remotely important or significant.

    Note: I have no citation or evidence that Slashdot has pursued this strategy besides observations like these, so this essentially pointless speculation on my part. Why did I bother to share it with the world then?

    Isn't there some fundamental irony here? I mean, UTC is based on GMT. This proposal is intended to fundamentally shift the time zone away from the meridian that was originally defined... by the UK... that runs right through the UK.

    The prime meridian is completely arbitrary, but out of the whole world, the UK was allowed to choose it and then base GMT/UTC from it. The more interesting implication is that this proposal is an effort to ensure your "noon" is no longer ever defined as the point when the sun is highest in the UK sky. I mean, the solar/astronomical observations at the Royal Observatory were putatively the reason GMT existed in the first place (and I guarantee the heavenly bodies haven't shifted, haha).

Even if you form an algorithmic construct that limits the domain such that the hash function could potentially be injective in the codomain, how do you ensure that it is surjective?

  9. Reverse combustion is a better bet on Stanford, UCD Researchers Say 100% Renewable Energy Possible By 2050 · · Score: 1
    The combustion reaction is roughly:
    hydrocarbons + O2 => energy + H2O + CO2

    There is nothing inherently preventing the reaction from being run backwards. Plants do it all the time. However, why not skip the plant stage? There are all sorts of problems with arable land being consumed for biofuel production, even if we disregard corn ethanol. So, why not make the hydrocarbons directly?

    This is not a new idea, and it is not theoretical only:

    We need to stop conflating petroleum's source with its capacity as a "battery". We are always going to need hydrocarbons for plastics, oils, etc. Also, the energy density of gasoline, at ~45 MJ/kg, is orders of magnitude better than the best battery technology available.

    It would be awesome to run reverse combustion at large-scale nuclear facilities. It would benefit from improved efficiency at the nuclear plants due to running the reaction on thermal energy rather than going through the relatively inefficient step of thermal to electrical conversion. This approach would be, by definition, carbon neutral. Hell, if we wanted to remove CO2 from the atmosphere we could just run the plants in overtime and pump the hydrocarbons back into the geological reservoirs we drained in the past (would the EPA have a problem with that? Hmm...)

    The potential benefits are significant: a single point solution that retains all the current infrastructure investment in petroleum distribution/consumption, no issues with hydrocarbon "self-discharge" like batteries/ultracaps have, excellent energy density, etc. We will always need hydrocarbons, so why wean ourselves off of them?

    ...just don't conflate the use of hydrocarbons with their source. If we can make the source clean/renewable, then what further problems exist?

  12. Re:The cycle to hell. on IT Turf Wars: the Most Common Feuds In Tech · · Score: 5, Insightful

    I've got friends who work in hospital security who have a devil of a time with people leaving their passwords and usernames on sticky-notes everywhere. Building security has problems with assholes defeating the building's fire alarm so they can sneak out to a fire escape (or worse yet, a ground-floor alley) and smoke and get back in.

    You had me up until this point. While your cited cases might be reasonable, there is also the all-to-frequent case where "security" regulations induce this behavior.

    What does hospital security expect users to do when users are required to rotate passwords every two weeks, have a 12 character long mix of upper/lowercase alpha's and numerics, and then also be subject to a 7 password history non-reuse restriction? Security is cognizant that the result of these provisions will be that users write down their passwords on stickies, so how is this more secure than allowing people to pick a less complex password and retain it longer?

    The answer is that this presumes that everyone is playing the same game, with the goal to be the best possible security equilibrium state balanced against inconvenience/usability. Running counter to this is security's CYA factor: they experience no penalty for the insane password restrictions that reduce overall security, because if there is a security breach from the post-it passwords they can dump all the blame on the hapless user for violating the published security protocol that prohibits such actions. So, security has a payoff table that disrupts the equilibrium resulting in the paradoxical, reduced security steady state that is observed in these cases (ie. security is externalizing the costs of implementing the high-grade security practices).

    PS. As for defeating the fire alarms, maybe they shouldn't have turned the entire hospital into a "tobacco-free campus", with the nearest "approved" smoking area located six blocks away. This is basic psychology. Normal people like to abide by the rules/laws even if they find them onerous, but there is a limit to their willingness to comply. This is essentially what happened to the entire US during the Prohibition. Again, as I said, your cited cases might be reasonable, but I have seen many that were not.

    It seems people in the US can get this same situation by joining the military. The government will reimburse college expenses and will guarantee you a job, but does not really care if the soldiers like their job assignment.

    And now, without USSR, I had to be flat out for get an education. And that education give me nothing but a certificate of degree. I had to work during my student days, because the rate of scholarships for students in Russia are quite funny.

    This sounds very similar to the US. Most students have to go into serious debt to finance their education, and the debt often requires decades to pay off. Many students work on-campus at the university for tuition waivers, but others help to finance their education via a regular job.

    I am uncertain what you meant by scholarship rates being "quite funny", but in the US the government and other institutions usually determine how much financial aid to give based on the student's family's income and wealth. That means students might not get much financial aid if their parents are not helping to pay for college, because the government formula expects the parents to pay part of the costs. Of course, there are also merit scholarships that can be won based on academic performance in high school and on standardized tests.

    As for the education giving you only a certificate of degree, requiring you to self-teach: all I can say is that I agree. Most of the interesting and useful things I have learned and used in my professional life I had to teach myself. However, to be competitive in the job market I needed to have my undergraduate degree. I got the certificate and that helped to launch my career.

    In addition to salting the password, I design my systems to sleep for one second after each failed password attempt, and for 3 seconds before booting the guy off. That should take care of brute force attacks.

    Depends on the scenario. If the attacker can deduce that an incorrect password causes the thread to sleep for one second (and successes return immediately), they can craft the attack to use this implicit information via parallelization by using a bunch of workers in a thread pool.

A normal user doesn't really notice 750 ms of additional latency when logging into a webapp, because they only do it once per session.

I prefer the apostrophe approach because any ambiguity can usually be resolved by parsing the sentence.

    "The CEO's went on a pointless junket" (no ambiguity: a possessive wouldn't parse)

    I must demur: I still am convinced that it's/its is a bug in English. Normal possessives are denoted by an apostrophe-s, as you pointed out. Whoever set the convention in English decided that a contraction had stronger claim to the use of the apostrophe and then just decided to "resolve" the possessive issue for 'it' by pretending it didn't exist. Hence, "it's" is a contraction for "it is" rather than the possessive. (BTW, here's an example of a pronoun/verb contraction rather than a verb/adverb)

    If it had been up to me, I would have awarded the apostrophe to the possessive, because I feel the possessive has stronger claim than the contraction. Also, if we defined "its" as the contraction for "it is", then there is no real weirdness introduced because pluralizing "it" makes no sense (it is singular by definition). Oh well.
