    The Bayesian is not even shown being Bayesian. Bayesianism is assigning prior probabilities to outcomes and then updating them based on the data, which he isn't shown doing in the comic. You can read between the lines and assume he's assigning a very low prior probability to the event that the sun has actually gone nova, but it's not shown. The problem is, a frequentist can just as easily translate probabilities into odds ratios, and thus come up with good betting strategies. The Bayesian is not doing anything that a good frequentist can't. Which brings us to the next point.

    The frequentist is, yes, being a frequentist, but he's also being a fucking idiot (i.e. a strawman). The really stupid part is that he uses the 5% criterion, which even in social sciences is usually only enough to conclude "hey, there might be something there, let's do a better study." Frequentists are allowed to (and do) require ``extraordinary evidence for extraordinary claims." For such an amazingly unlikely event as the sun going nova, a non-strawman frequentist would require something like 0.0000001% significance level, which the machine obviously cannot provide. The non-strawman frequentist wouldn't bother using the machine at all, since it obviously cannot satisfy his criteria (the best significance it can give is 1/36, which isn't good enough).

    The significance level here is "the probability of observing the evidence we observed, if the null is true," in this case the null hypothesis being that the sun has not exploded. A frequentist is allowed to use "prior information" to set the significance level. He just isn't allowed to say something like "Before I look at the machine, I think there is a p% chance that the sun has exploded, and a (1-p)% chance that it has not." (This is a Bayesian approach which, as I mentioned, the Bayesian doesn't actually do in the comic.) A frequentist is only allowed to judge how likely it is that the evidence is a false positive, and this likelihood is the significance level.

    I hope this is clear; it's hard to explain this stuff sometimes.

    more likely, he just think it's cool and will get over it in a few days when he finds himself toggling to the standard clock mode for every appointment, but whatever.

    People should be thankful for having an opt-out robots.txt at all. It would in most cases not violate copyright for Google to ignore it completely (it might violate the site's TOS, but it is questionable whether even this holds any weight); they are just courteous enough to honor it. robots.txt is there mostly to prevent servers from being overloaded, or to keep content private, not to enforce copyright on publicly-facing content.

    This is the same as any NLP crowd-sourcing tool; it's simply designed with a focus on correlating vocabulary with prejudicial sentiment. No one is planning to use it to pass restrictive laws. It's just useful for people who are involved in a country, but are not fluent speakers of $foo or involved in the right subcultures, to know that a certain word has now acquired a negative connotation.

    Prior restraint. If a website entirely forbids the posting of an entire class of image, let's say abstract art, then because this law establishes a criminal charge for doing so, it should be considered prior restraint in that case.

    Since this law does not rule out cases like the above (and it would be incredibly difficult or impossible to write it in such a way that it did), and there almost certainly are websites with such restrictions in their TOS, it thus violates the first amendment quite grievously. As long as national security isn't involved, courts take prior restraint quite seriously.

    There is no way in hell that this clause will stand. They'll remove it soon and make hay over how it shows that they care about freedom, blah, blah, blah.

    A non-practicing entity could still acquire patents and troll with them, if they were the original assignee. So, it's a conservative law; it attacks only the most flagrant case of trolling, while giving the benefit of doubt elsewhere. Upon a few seconds of reflection, one realizes that this is a good thing.

  25. Re:What? on Controversy Over Violet Blue's Harm Reduction Talk · · Score: 1

    I find trigger warnings asinine. In their current form, they evolved in response to shorter and shorter fiction. For example, a full-length movie or novel will, generally, have some kind of review or advertisement about its content, so no problem; anyone can make an informed decision. Trigger warnings in their current form, afaict, caught on first with shitty four paragraph-long fanfic, so by the time you've read it, you've already been subjected to a crude depiction of pony/vampire rape written at a sixth-grade level. Hence, a prologue comprising a list of `triggers'.

    Now we have gone further; the title of a talk, ``sex +/- drugs: known vulnerabilities and exploits," itself is enough to merit a warning. Maybe you've deduced my point already. If that title is enough to `trigger' someone, how isn't ``trigger warning: contains a very oblique reference to drug-related rape" capable of same? Maybe we instead can use a more gentle warning, perhaps, ``trigger warning: contains reference to chemicals and forced sex"? But the phrase ``forced sex" is a bit rough. Maybe instead we can say ``trigger warning: contains reference to chemicals, sexuality, and vulnerability," or ``trigger warnings: contains reference to drugs, sex, vulnerability and exploitation"?

    Do you see what i did there? The title of the talk is already a trigger warning (albeit accidentally, as the content was not actually about rape). It just wasn't sanctioned as one by the self-appointed gatekeepers of culture and sanity, so out it goes.

    This has been about this particular trigger warning which is especially ridiculous; however, I think they all are. As someone has said about this topic: Give me life, give me pain. Give me myself again. Life isn't going to go away; if you try to sanitize it, you pathologize yourself and everyone else.
