  1. Re:Transposition error on 737 'Tailstrike' Caused By Typo On a Tablet (arstechnica.com) · · Score: 1

    First, when working out the plane's takeoff weight on a notepad, the captain forgot to carry the "1," resulting in an erroneous weight of 66,400kg rather than 76,400kg. Second, the co-pilot made a "transposition error" when .... "Transposition error" is an investigatory euphemism for "he accidentally hit 6 on the keyboard rather than 7."

    A transposition error would have been swapping the position of two adjacent glyphs, for instance coming up with "64,600".

    Typing in a "7" when it should have been a "6" in the number "66,400" is a transcription error. Those are very different errors, typically caused by very different things.

A lot of people prefer Cygwin's bash, but the licensing on msys is nicer, and all you really lose is some POSIX stuff that isn't all that important unless you are trying to perform a Unix port of something.

    Atword actually thinks that a computer program can fix human behavior.

    This is a bit of a caricature, with a grain of truth to it. His general philosophy (at least when he's talking about it) is to design the system your website operates under to encourage good behavior, discourage bad behavior, and be self-correcting by users (who there will be lots more of than administrators).

    So while the flaming a-holes will always be among us, they don't get the satisfaction on say a SE site they can get on a dumb message board. Its not "fixing" human behavior, its working with it rather than trying to fight it. Sort of Zen website design.

    We are talking economics here. In this respect, labor isn't significantly different than most other widgets. If there's a spike in demand for Oil, first prices spike way up, then people start producing more oil from more marginal sources and the price spike goes down a bit. In the meantime marginal demand sources (eg: the guy who would kind of like to visit Aunt Edna in St. Louis if gas isn't too expensive) will get priced out.

    There's no reason labor won't be the same way. I am quite happy where I am. But if you wanna pay me way more for what I can do than what I'm currently getting, you'll be much more likely to see my resume. If my employer wants me just as bad, they will be forced to match that. Eventually one of you will get past what you are willing to pay to have that work done. Big labor price spike. In the meantime, other engineers will see this price spike, relative to what the other things they can do will pay, and will learn to do it to. Hungry smart college students will go into that line of STEM if it pays enough in comparison to medicine and/or law. With the new supply, the spike will go down, but probably not to its original level.

    In economics, we draw one diagonal line between cost and amount (of labor) that is roughly proportional and call it the "supply" line. The more you will pay for labor type X, the more people will offer that. Then we draw another diagonal line between those two things that is roughly inversely proportional and call that the "demand" line. The cheaper labor type X is, the more of it employers will be willing to ask for. The point where those two lines meet is the market price.

  8. User Reputation, Moderating, and Discourse on Interviews: Ask Stack Overflow Co-Founder Jeff Atwood a Question · · Score: 4, Interesting

    I think its probably inarguable that the biggest innovation StackOverflow brought to the web was the centrality of reputation and user moderation to its design. Sure, our own /. had done something similar years before, and it was hardly the first either, but no website I know of had before taken it to its logical conclusion in quite the way SO does. This effectively "crowdsourced" a lot of traditional website administrative activities, which turned out to be an incredibly powerful idea. Practically all the functionality of SO is built around the concept.

    So when I saw you were tackling online message boards, I expected the same kind of thing. But browsing around a typical Discourse thread, I'm not seeing that at all. Sure, users can "heart" posts, but all that does is bump a small counter next to the heart. There is no way to tell at a glance which posts users found the best and/or worst. Higher rated posts don't sort to the top, or get bigger or anything. As a result, I don't even see that feature used much. Certainly its nothing like SO, where post voting is the central activity. It also seems like moderation on Discourse is designed to be done by administrators, not users. I don't see any facility for users getting moderation privs as they gain reputation. Compared to SO, Discourse seems kind of, well, like a big step backwards in interactivity.

    I'm sure I'm missing something here. What is it? Or did you really decide SO's centering of its design around users and their opinion on posts was a mistake, or perhaps just not a good fit for a more generalized discussion board?

  9. Re:Rampant closure of questions on Interviews: Ask Stack Overflow Co-Founder Jeff Atwood a Question · · Score: 1

    Another common reason for closure is the "duplicate" question meme in which nuance is overlooked and questions are marked as duplicates because the people doing the marking failed to understand or appreciate the difference. This is very annoying.

    My most aggrevating run-in with this was the day I got an unexplained set of downvotes on a years-old answer, along with a comment (thank you commenter!) expressing confusion as to how it addresses the question. Comparing the two, he was right; my (fairly highly-rated) answer made no sense at all. After a very confusing 30 minutes, I finally figured out that the following had happened in the intervening years:

    1. Months later, the question had been closed as an "exact duplicate" of another question that was only remotely similar (Answer authors are not notified when this happens)
    2. Some later moderator had come along and merged the two "exact duplicate" questions.
    3. Users found the question on the main page (due to the merge popping it up), found all the answers for the old question that made no sense whatsoever for the new question, and proceeded to downvote them

    A lot of this could be avoided simply by applying a rule that if answers to a question A make sense for it, but not for another question B, then the two questions by definition are not "exact duplicates". However, people on SO just luuuuve to close questions, given half an excuse. Asking for even this much analysis is way too much for a lot of people, and on a huge stack 5 such people isn't a very large hump to get over.

    I'm a software engineer at a large multinational, and we've been trying to find qualified candidates for software positions, but we're having a REALLY hard time. There just aren't any qualified people available. This idea that there are competent, qualified STEM people out there who are being denied jobs by the H1-B program just doesn't seem to jive with reality.

    Major economics fail here. Are you trying to tell us that if you doubled or quintupled the salary for those positions, you still would not be able to find people capable of doing them? Good qualified engineers would not happily leave their other jobs for a far better paying one at your company? I'm pretty happy where I am, but for a 5x bump in salary I'd probably be happy to buy a few extra layers of clothing and move up north.

    But as somebody who actually studied economics a wee bit, it looks to me like you are saying, "We can't hire anyone for these positions at the price we want to pay them." In normal markets, this is where, well, market forces take over and cost rises up to the point to encourage an increased supply sufficient to cover the demand (at that price). Supply and demand are independent curves, and the market price is the point where the two meet.

    What I'm seeing you say here is "We don't want to pay the market price for this labor."

    Aloha Airlines 243 had a massive structural failure of the fuselage while at cruising altitude. The cause was put down to metal fatigue. So it has been known to happen.

    On 16 November 2001, while operating for Middle East Airlines as F-OHMP, the aircraft suffered a tailstrike landing in Cairo. It was repaired and went back into service with the airline in 2002.

    Another incident that comes to mind is Aloha Airlines 243, which was also a cruising altitude when a large part of the fuselage suddenly ripped off the plane for no apparent reason. "Metal fatigue" was cited. The only fatality was a flight attendant who happened to be standing in the aisle by the new hole in the plane. So it is certainly not unheard of for there to be fuselage failures at cruising altitude (where the air pressure differential would be greatest) rather than takeoff or landing.
