  1. Re:Pure Oxygen? on Revolutionary Scuba Mask Creates Breathable Oxygen Underwater On Its Own · · Score: 1

    You need about 0.2 ATM oxygen partial pressure at more or less any altitude. So even at the surface this thing would need other gasses to keep you healthy. If it's got some sort of gas segregation technology it's possible to build a re-breather system that mostly re-uses the non-oxygen, non-CO2 gasses, but that's not a trivial task even if you have a readily available supply of oxygen.

  2. Re:XBMC ftw on Ask Slashdot: Suggestions For a Simple Media Server? · · Score: 5, Informative

    Plex uses an internal ffmpeg to decode (and transcode, if needed) media files -- if it doesn't play there it will be hard to play in general. And you don't need to muck with an OS-level codecs, as Plex won't see or use them anyway.

    But that's not relevant in this discussion; Plex will add files to the library even if it can't read them, so long as it can figure out from the file path what they are. If you need Plex to parse the tags in the file it will have to be able to decode it, but if it can match based on the name it doesn't care if the file can even be opened.

    The problem is almost certainly a naming issue, or possibly a selection of the wrong scanner type. If you select a TV or Movie scanner Plex will only add files it can specifically match to databases like thetvdb.com, and you must use one of the naming conventions to help it do so. If you just want it to put up all of your media as-is without matching against a DB you need to select the "Home Videos" scanner type, which simply walks the filesystem and builds a matching hierarchy in the Plex library. And of course Music has its own scanner, which can similarly match against Last.fm or simply read local tags, depending on wishes.

    It's not quite brain-dead simple if you have a mess of unorganized media, but it's not hours of work either, and the DB-matching modes provide rich metadata with all the hassle of ensuring that your paths include the series title and episode number somewhere along the line.

    That's a one-time problem though -- it's a barrier, but it's a small one given how frequently mail is used. And modern mail clients are happy to guess virtually all of the settings, at least if your mail server has a standard configuration and you can remember your own email address.

  4. Re:A false sense of security on Security Expert: Yahoo's Email Encryption Needs Work · · Score: 1

    You can select which ciphers you accept. In Firefox the preference is something like "security.ssl3.rsa_rc4_128_md5" -- I'm sure if you search for RC4 in the about:config page you can find the relevant settings. You can explicitly allow or disallow whatever combination of ciphers you like.

    And it's not a "false sense of security" when the indicator is binary. It's not as descriptive as telling you what cipher is in use, but it's still encrypted and would take a lot of effort to decrypt (weaknesses have been demonstrated but there's no known attack that's even vaguely plausible in the general case), so given only binary choices "secure" is probably the right one, at least for the time being.

    I don't think it's quite as simple as that, either. The imbalance of power is part of the point -- after WWI large industrial power engaged in fewer direct conflicts. Arguably at least part of the reason superpowers don't engage, and the reason fewer people die, is because weaponry is more advanced.

    We should all stop being coy about what we used to make, so that employers lose their knowledge advantage in salary negotiations. Your salary is currently being depressed because you *don't* know what other people are making.

  12. Re:Standard stuff for public employees on Tech Startup Buffer Publishes Every Employee's Salary, Right Up To the CEO · · Score: 1

    The problem with not publishing salary data is this: employers have asymmetric knowledge of salaries which puts them at a huge negotiating advantage, driving down the average salary. Which is far and away the #1 reason that companies discourage discussion of compensation. This basic economic fact is true in any market with asymmetric knowledge and there's absolutely not reason that you as an employee should want such a thing in the job market -- you'd be much better off in your negotiations (and they'd be simpler and faster for everyone involved) if both you and your employer had access to the same information about compensation.

  20. Re:So what? on Female Software Engineers May Be Even Scarcer Than We Thought · · Score: 1

    So you're aware that there's a bias, and you don't have any explanation for that bias, but you're somehow sure it's not the result of gender discrimination? How does that work?

    Women might well be avoiding coding because of the social environment. But why is that a necessary component of coding jobs -- if it's not that's an example of gender discrimination, not evidence against it.

    Try framing this issue differently:
    All people, regardless of gender, are different and have different interests. Some of them will be more interested in coding than others. But given an arbitrary segregation factor -- eye color, for example -- wouldn't you expect the distribution of the general public to match the distribution among coders? And wouldn't you want to understand why a bias existed if you found one?

    Maybe that bias is directly related to suitability for the job; the ability to exchange data with a computer is strictly necessary for coding so people who have trouble with human-computer interfaces are less likely to be coders and we're probably okay with that. But if you don't understand exactly what causes the bias how can you assume it's not discrimination?

If the thing titling the playing field is something we understand and directly control it's easy to fix, but that's not always the case, and I don't think it's not acceptable to say "well, the results are biases but I don't know why so I guess we'll just have to accept the bias" -- I actually want to understand the cause and resolve it as necessary, even if it's hard.

    Complain all you want about the particular way that people try to solve problems, but the idea that we should just ignore biased outcomes under the assumption that nothing is wrong is absurd.

    Charging for parking doesn't do a lot to regulate demand, it's done to regulate turnover. Essentially all publicly-run pay parking is also time-limited, and frequently the rate for short-term usage is lower than commercial parking in the same area. Demand for parking is more or less inelastic because people still need to go places whether or parking is expensive; at best expensive parking encourages the use of other modes of transit.

    Turnover isn't actually an issue on public conveyances; loitering *could* be, depending on the circumstances, but most transit systems include a layover point where it's easy to determine if someone is merely camping out.
