    The simple solution here is to have the senior manager in the room WHILE he's interviewing the candidate if that was the case.

    I don't see why you've jumped to the conclusion that a senior manager won't be in the room for some or even all of the process, or why you continue to suspect that senior management wouldn't make or be involved in the hiring decision. I get the impression that you haven't been involved in a lot of hiring or interviewing at this level.

    That said, there are a lot of reasons why a senior manager wouldn't necessarily want or need to sit in on the entire interview. Depending on the size of the company and the responsibilities of the people involved, a senior manager might not have time to sit through an extended, specialized discussion. Some companies have an interview process that extends over several hours, and may even be spread over multiple rounds on separate days. Management may also want to get a sense of how the candidate performs in one-on-one situations, instead of when faced with an interrogation by the senior manager, the senior manager's assistant, the HR rep, and the technical subordinate all at once. For that matter, the senior manager may not want to make the subordinate nervous.

    Let's think about this. The original question didn't say anything about hiring, just about interviewing.

    I strongly suspect that the final hiring decision will come from a senior manager higher up the chain, based ultimately on that senior manager's own judgement. That decision will, however, be informed - in part - by the input he receives from the underlings who participated in the interview process.

    And that's a Good Thing, for everyone involved. Senior management needs to know if prospective management candidates will be able to interact effectively with their technical and non-technical subordinates. One of the ways to assess this is to put them in a room together.

    It's also possible that senior management recognizes their own limitations, and want to have someone who is able to assess or test the candidate's claims about his own technical abilities. It's not unusual for a company, when hiring, to carry out several rounds of interviews testing (explicitly or not) different aspects of the candidate's skills and knowledge, and introducing them to different parts of the company's structure and personnel, with each.

    Isn't making the elevator go faster a job for an engineer? Does one really need to be a mathematician to know that a faster elevator moves people faster?

    I suspect that the problem here is a failure on the part of the article writer. The author was probably just looking for any sort of answer to 'What's the most famous building you've ever done any work for?', rather than 'what's the most mathematically-interesting part of your job?'

    It's also possible that there's a little bit of complexity being glossed over here. For the Empire State Building, visitors take up to three consecutive elevator rides to get to the observation decks: one to get up to the 80th floor, another from 80 to 86 and the main observation deck (though the hearty can take the stairs), and an optional, extra-charge trip from 86 up to the topmost observation area on 102. Visitors form queues for tickets, security, and each elevator ride (both up and down).

    While speeding up any of the elevators might seem like a good thing, it runs the risk of causing crowding and bunching of passengers waiting for the now-overloaded next stage. Making one set of elevators faster could increase wear and tear on those elevators (and increase both energy use and passenger discomfort) without improving overall throughput; I can see how there might be some serious mathematical optimization going on there. As well, it's possible that our mathematician was involved in optimizing all of the building's elevator speeds and timings, and not just the elevators dedicated to observation deck service: a much more difficult optimization problem.

    The way to prevent this kind of mistaken (or even malicious) trade is to stop protecting the trader by canceling the trade as soon as the mistake is realized. If you issue a trade order, you should be liable for paying for it. If you can't, normal bankruptcy laws should apply.

    First of all, it's not clear exactly what the trade order even meant. At worst, an offer to buy -6 futures should have been interpreted as an offer to sell 6 futures at the stated price--not as an (underflow-generated) bid for 4 billion futures. Who, exactly, do you hold liable for failing to sanity-check their inputs--the trader, his company, the exchange, their various software subcontractors who themselves may have been bought, sold, and restructured long since...?

As Samsung has made clear and Apple cannot dispute, Mr. Hogan made public statements after the verdicts that so clearly favored Apple that the press speculated about their possible financial ties.... Only by chance did Samsung discover the suit by Seagate against Mr. Hogan while it was investigating these other potential bias issues reported post-verdict; and because the court file no longer exists, it was even later that Samsung discovered Mr. Hogan’s lawsuit against Seagate when Mr. Hogan himself disclosed it in an interview....
    Nevertheless, Apple insists that Samsung waived because it “could have” and “should have” discovered the dishonesty before it actually did so by ordering Mr. Hogan’s 1993 bankruptcy file during voir dire.... Even apart from the impracticality of this suggestion (it took a week to receive the file after it was ordered post-verdict[...]), the Court should reject Apple’s untenable suggestion that trial counsel should engage, upon pain of waiver, in scorched-earth, extrajudicial investigations into a sitting juror’s life, absent any reason to believe that they lied on voir dire or otherwise warranted such an intrusion upon their privacy.

The Court asked Mr. Hogan about his prior lawsuits; Samsung was entitled to rely on the truthfulness of his answers.

    Samsung argues that when asked, the juror deliberately withheld key information about his own legal history.

    It is no answer, as Apple suggests..., that Mr. Hogan revealed another, unrelated lawsuit involving a former employee. To the contrary, a juror is presumptively biased where “she told the part truth that was useless, and held back the other part that had significance and value.” Clark, 289 U.S. at 10-11 (juror “counted off a few [past jobs] and checked herself at the very point where the count, if completed, would be likely to bar her from the box”); see Dyer, 151 F.3d at 983.

    I live in a so-called "majority-minority" district which was considered a lock for a minority candidate since its creation. The incumbent has done such a poor job that he came fairly close to losing the election in 2010. The response? They adjusted the lines to pull extra minorities into his district to ensure that would never happen again.

    Incumbents tend to enjoy advantages in terms of resources and name recognition that can make them inherently more difficult to beat, even in the absence of race politics.

    A local challenger can be further hamstrung by platform elements adopted at the presidential, federal, or state level that are unpalatable within a district (or unpalatable to a significant group living within that district).

    There's a further vicious circle at work where a party decides that a seat is unwinnable, and therefore doesn't put any resources into recruiting effective candidates or running more than a pro forma campaign, and therefore finds that the seat is unwinnable, and so doesn't put in any effort...

    There are at least two routes around the problem. First, find a credible non-minority candidate who can demonstrate an ability to work with groups (majority and minority ethnicities) within the district. Not only does this require time and effort, but it may also require the candidate to butt heads with the state or federal party. Second, the cynical route is for your party to find a minority candidate of its own. You've just told me that the district has lots of them; can't you find any of them who want to represent the (Republican) party locally?

    The downside of that second approach is that you can't go blaming race anymore when the party still loses; you might have to start looking at why your policies are so unappealing to the minority population.

    No, no, no. A kWh (kilowatt hour) is an amount of energy equivalent to drawing one kilowatt (one thousand watts) continuously for one hour: one thousand joules per second, times 3600 seconds per hour, gives 3.6 million joules per hour in one kWh. For comparison, one kilowatt is the amount of electricity drawn by roughly fifteen incandescent light bulbs, or by one smallish toaster. The average U.S. household uses on the order of 1000 kWh per month.

    Using your estimate of 1,432,500 watts - 1432.5 kilowatts, trivially equivalent to 1432.5 kWh per hour - for the power draw for SETI@home, we get a consumption of 0.398 kWh per second. Using your figure of 6.89E-4 tons CO2 / kWh, that comes to 0.000274 tons per second, or about 274 grams (a little over half a pound -not three thousand tons - per second). In total it comes to about a ton of CO2 per day.

    That's not a negligible amount of CO2. It comes out to the equivalent of the electricity use of about a thousand U.S. homes. (Note that that doesn't include household CO2 contributions from other sources, particularly fossil fuels burned for home heating, water heating, clothes drying, and transportation.)

These are among the heavier components aboard many satellites, so our hypothetical 'repair and resupply' launch is already going to be costly and heavy before you add all that unique and highly flexible hypothetical manipulator hardware. From any sort of rational economic standpoint, if you're going to launch a heavy, expensive satellite, you might as well launch a replacement (with all-new hardware, up-to-date electronics, incorporating the lessons learned from the previous iteration, etc.) instead of trying to fix or cannibalize the dodgy one in orbit.

    Trying to service multiple satellites with one launch of our Swiss-Army-knife repair droid gets even worse, because manoeuvring between orbits tends to be very costly in terms of fuel (prohibitively so if a significant change in inclination is contemplated) and therefore weight.

    And how user-serviceable are most satellites? Anything that's already in space now (or that is likely to be launched in the next decade) hasn't been designed to be repaired, modified, or scavenged after launch. Are we really solving the 'space junk' problem if our repair droid is inadvertently leaving behind a cloud of dropped screws and broken hardware? One satellite is easy to track and avoid. A haze of screws and plastic chips is not--and will still put a hole right through the ISS.

    The folks at DARPA are sometimes crazy, but they're not usually idiots. Presumably they've been able to come up with the same objections as Slashdotters, and they probably realized them faster than we did. So what's really going on?

    1) A stripped-down version of this tool could be used to attach de-orbiting or manoeuvring thrusters to disabled satellites that happened to be occupying (or threatening) particularly high-value orbital real estate. The ISS has to be periodically repositioned to avoid the occasional bit of space junk. Further up, there's a limited amount of space in geostationary orbit, and a malfunctioning satellite could be trouble as either a source of physical or radio clutter. If the program fails to produce its rather pie-in-the-sky 'dream' goal, it could still develop this useful sideline.

In that more-likely scenario, the parent's calculation is closer to the mark. Each of six positions could have any one of 52 values (26 upper- and 26 lower-case letters), giving 52^6 possibilities, from which we subtract 2*26^6 options, representing the forbidden all-lower-case and all-caps passwords, leaving 52^6-2*26^6 possible choices.
