Ask Slashdot: Hungry Students, How Common?

Gud (78635) points to this story in the Washington Post about students having trouble with paying for both food and school. "I recall a number of these experiences from my time as grad student. I remember choosing between eating, living in bad neighborhoods, putting gas in the car, etc. Me and my fellow students still refer to ourselves as the 'starving grad students.' Today we laugh about these experiences because we all got good jobs that lifted us out of poverty, but not everyone is that fortunate. I wonder how many students are having hard time concentrating on their studies due to worrying where the next meal comes from. In the article I found the attitude of collage admins to the idea of meal plan point sharing, telling as how little they care about anything else but soak students & parents for fees and pester them later on with requests for donations. Last year I did the college tour for my first child, after reading the article, some of the comments I heard on that tour started making more sense. Like 'During exams you go to the dining hall in the morning, eat and study all day for one swipe' or 'One student is doing study on what happens when you live only on Ramen noodles!'

How common is 'food insecurity in college or high school'? What tricks can you share with current students?"

"Specifically, the attacker repeatedly sent malformed heartbeat requests to the HTTPS web server running on the VPN device, which was compiled with a vulnerable version of OpenSSL, to obtain active session tokens for currently authenticated users," Mandiant's Christopher Glyer explained.

Russia Writes Off 90 Percent of North Korea Debt

The rest of the debt, $1.09 billion, would be redeemed during the next 20 years, to be paid in equal installments every six months. The outstanding debt owed by North Korea will be managed by Russia's state development bank, Vnesheconombank. Moscow has been trying to diversify its energy sales to Asia away from Europe, which, in its turn, wants to cut its dependence on oil and gas from the erstwhile Cold War foe. Russia's state-owned top natural producer Gazprom is dreaming shipping 10 billion cubic meters of gas annually through the Koreas.

To *be* bat-shit crazy, or to *appear* bat-shit crazy? Appearing insane can be an excellent military strategy, especially if you're in an extremely week tactical position such as North Korea is in. It makes your enemies extremely hesitant to provoke you because you may quite possibly engage in a completely disproportional and/or unexpected response. Of course keeping up the appearance requires that you do occasionally actually engage in insane behavior, but a sane commander using such tactics will be extremely canny in employing such behavior only when a studied analysis of the enemy suggests that he can get away with it with minimal real costs. The fact that North Korea is not only still standing, but has managed to repeatedly milk the western world for lucrative concessions despite the apparent insanity of its leaders, strongly suggests that that is the case.

Of course the beauty of such a strategy is that your enemy can never be completely sure exactly how much is an act, and must moderate their own behavior in the face of that uncertainty. Would North Korea launch an all-out attack on our regional allies in response to some moderate provocation, knowing full well that they would be completely obliterated in response? Certainly not.

The Design Flaw That Almost Wiped Out an NYC Skyscraper

"According to LeMessurier, in 1978 an undergraduate architecture student contacted him with a bold claim about LeMessurier's building: that Citicorp Center could blow over in the wind," writes Werner. "LeMessurier realized that a major storm could cause a blackout and render the tuned mass damper inoperable. Without the tuned mass damper, LeMessurier calculated that a storm powerful enough to take out the building hit New York every 16 years."

Kansas City Hyatt Regency Skywalk

By careysub • Score: 5, Interesting • Thread

I've heard news reporting before on this subject. The way it goes is this: the architect submits his designs, which are subject to review. Once the green light's given, construction begins. Now, engineers on the project notice a way that they can cut costs or construction time, or somebody requests a modification to the original design (perhaps to add a restroom or breakroom, perhaps to add or remove a wall or subdivide a floor differently). ... I wish I could find an appropriate citation ...

The Kansas City Hyatt Regency Skywalk disaster, 17 July 17 1981, is an excellent case study. Before the collapse of the WTC South Tower it was the deadiest structural collapse in U.S. histories (dam failures are another story entirely). Until 9-11 the CitiCorp Center was well placed to beat it.

In the Hyatt Regency case the design of the double skywalk was changed during constructution, replacing a continuous steel rod that supported both skywalks with two rods, one from the roof to the upper skywalk, and one from the upper skywalk to the lower. Problem was the design had the continuous rod bearing the full load, the change made the upper skywalk bear the load of the lower skywalk (and the people on it) when it was only supposed to be holding up people on the upper skywalk and nothing else.

As built the skywalk was so overloaded that eventual collapse was possible even without any load. Naturally when it did fail it would be at a time when both the upper and lower skywalks were heavily loaded with people, and the floor crowded below. 114 died, 216 were injured - many seriously.

By pepty • Score: 5, Informative • Thread
Three different sources, four different versions of the events (the Slashdot summary cobbles together its own take). I wonder which version is closest to the truth?


Diane Hartley contacted him to ask some technical questions about the design, which he was delighted to address. Hartley's professor had expressed doubts regarding the strength of a stilted skyscraper where the support columns were not on the corners. ... But the conversation got him thinking, and he started doing some calculations on just how much diagonal wind the structure could withstand. He was particularly interested in the effects of an engineering change made during construction which had seemed benign at the time: numerous joints were secured with bolts rather than welds.


According to LeMessurier, in 1978 an undergraduate architecture student contacted him with a bold claim about LeMessurier’s building: that Citicorp Center could blow over in the wind. The student (who has since been lost to history) was studying Citicorp Center and had found that the building was particularly vulnerable to quartering winds (winds that strike the building at its corners). Normally, buildings are strongest at their corners, and it’s the perpendicular winds (winds that strike the building at its faces) that cause the greatest strain. But this was not a normal building. LeMessurier had accounted for the perpendicular winds, but not the quartering winds. He checked the math and found that the student was right. He compared what velocity winds the building could withstand with weather data and found that a storm strong enough to topple Citicorp Center hits New York City every 55 years. But that’s only if the tuned mass damper, which keeps the building stable, is running. LeMessurier realized that a major storm could cause a blackout and render the tuned mass damper inoperable. Without the tuned mass damper, LeMessurier calculated that a storm powerful enough to take out the building his New York every 16 years.

The student wondered about the columns--there are four--that held the building up. According to his professor, LeMessurier had put them in the wrong place. "I was very nice to this young man," LeMessurier recalls. "But I said, 'Listen, I want you to tell your teacher that he doesn't know what the hell he's talking about, because he doesn't know the problem that had to be solved.' I promised to call back after my meeting and explain the whole thing." When LeMessurier called the student back, he related this with the pride of a master builder and the elaborate patience of a pedagogue; he, too, taught a structural-engineering class, to architecture students at Harvard. Then he explained how the peculiar geometry of the building, far from constituting a mistake, put the columns in the strongest position to resist what sailors call quartering winds--those which come from a diagonal and, by flowing across two sides of a building at once, increase the forces on both. For further enlightenment on the matter, he referred the student to a technical article written by LeMessurier's partner in New York, an engineer named Stanley Goldstein. LeMessurier recalls, "I gave him a lot of information, and I said, 'Now you really have something on your professor, because you can explain all of this to him yourself.'"


LeMessurier had long since established the strength of those braces in perpendicular winds--the only calculation required by New York City's building code. Now, in the spirit of intellectual play, he wanted to see if they were just as strong in winds hitting from forty-five degrees. His new calculations surprised him. In four of the eight chevrons in each tier, a quartering wind increased the strain by forty per cent. Under normal circumstances, the wind braces would have absorbed the extra load without so much as a tremor. But the circumstances were not normal. A few weeks before, during a meeting in his office, LeMessurier had learned of a crucial change in the way the braces were joined.

True, but not the cause for the crash.

Yes, the pilots were the cause for the crash. They even made remarks about the unusual attitude. The situation was obvious, and their ignorance and lack of competence was staggering. Just because the automation was switched off due to an iced probe does not mean the automation is to blame. Ask pilots why they think themselves to be indispensable, and you get some airy stuff on the line of "catch mistakes in the systems that nobody foresaw". And yet, when exactly this happens, they did actively, but unwittingly, do their utmost to crash the airplane in circumstances when continuing the flight uneventfully would have been the by far most likely outcome.

This is one of the most often repeated misunderstandings in aviation: the vast majority of crashes is caused by pilots, so we should replace them with automation since that's much more reliable. Errr... no, not by a long shot.

The vast majority of crashes is due to pilot error because the vast majority of possible crashes due to equipment failures are prevented by the pilots. I am a pilot, have never been in a crash, but have had several autopilot and other failures where, if we had not intervened, the aircraft would have crashed. But of course, all those possible crashes due to equipment failures don't make it into the statistics because no actual crash occurred. It's merely a note in the company's safety magazine for crews (along with dozens of others each month). So when an aircraft does crash (even if it's due to equipment failure), it's usually still considered the pilots' fault, and correctly so, because they should have been able to prevent it.

Take the Turkish Airlines that crashed in Amsterdam. Due to a radio altimeter failure during an automatic approach, the aircraft thought it was directly above the runway and pulled the throttles back, while in fact it was still several hundred feet above the ground. Most crews would have seen the speed decreasing (and indeed, this kind of incident had happened many times before to other crews without causing a crash) but this crew reacted much too late and "caused" the airplane to crash.

Or take the Air France that crashed after the pitot tubes froze up. The automation actually failed so the pilots had to take over. Without pilots, the airplane would have crashed anyway. And here, too, this kind of incident had already happened to other crews multiple times, but each time the crew had handled the situation correctly (even though it was not something that was trained in the simulator or accurately described in the procedures). This time the crew did not handle it correctly, in part because they were confused by conflicting warning messages from the airplane's systems telling them the plane was overspeeding and stalling at the same time. They even got aural warnings when they started to, temporarily, apply the exact correction they needed to meke. The automation was not helping them, but actually working against them and telling them they were wrong when they were, in fact, right.

If you want to have an idea of how reliable automation is, just look at the number of military drones that have crashed so far. Their mission couldn't be simpler: take off, fly over some area, come back and land. They only fly in relatively nice weather, there are vaslty less drones than passenger aircraft, yet there are many more drone crashes than passenger aircraft crashes.

It's certainly a good thing that Darpa is trying to make aircraft automation more reliable, but right now pilots are still by far the most important asset for the safety of an airplane.

The full report on the AF447 flight paints a somewhat different picture than the media described. The pilots were at fault, but not as blatantly as it seemed. A badly designed controls interface hid the airspeed indications (which were correct but so low that the computer flagged them as invalid).

The trim feedback system normally adjusts the elevator trim so that the joystick can be kept centered. In this case, since the aircraft pitch wasn't responding normally, the slightly back stick position caused the trim to continuously put in more up elevator.

The pilots set the correct pitch and full power - in normal conditions this would have worked. The problem here was that since the plane was in a deep stall, the angle of attack was much larger than the pitch angle.

The stall indicator cuts out when the angle of attack and airspeed are out of a reasonable range. At one point early on, the co-pilot started to put the nose down, but the stall alarm turned ON (because the angle of attack was no longer to large as to be invalid), and in response he pitched up again - probably having confused the stall indicator with some other warning. Note that the plane was in the coffin-corner where stall speed and mach overspeed are quite close together.

The pilots *should* have figured this all out, but it wasn't trivial to do so with the information they had available. Airliner accidents are almost always due to a long chain of unlikely problems.

It got up there while carrying a lot more propellant and a whole second stage. The braking burn uses only 3 engines to limit the acceleration and ends with just enough propellant left to stop it when it reaches the ground. On top of this, it gets passive aerodynamic braking the whole way down.

The mass ratio for the first stage burn, burdened with the second stage and braking propellant, is probably around 4, and a braking burn with equal delta-v would need the same mass ratio, except with no second stage and ending with the rocket empty. The overall first stage mass ratio is around 30, so all else being equal, a return would take around 3/29 = 10% of the propellant on the first stage. But all else is not equal, the returning rocket is mostly empty tanks descending through a thick atmosphere that provides plenty of braking, so the final burn only has to bring it to a halt from terminal velocity, and I omitted the second stage propellant. Overall, 4% sounds quite reasonable.

Cost breakdown

By Immerman • Score: 3 • Thread

So, is NASA currently paying a nearly 3x premium to SpaceX just to get their technology off the ground or what? Not that I object to such long-term thinking, quite the opposite in fact, but I could swear the SpaceX contract was marketed as a cost-saving maneuver.

It says here that it currently costs $10,000 to get a pound of payload into orbit, but from TFA SpaceX has a $1.6 billion contract for 12 launches, and if the current ~5000 pound payload is typical that works out to ~$27,000 per pound. Granted, assuming SpaceX perfects the reusable F9 that stands to potentially reduce launch costs 5 to 20-fold, easily making it one of the cheapest options available, even assuming that the current contract strictly covers launch costs and profit and without any R&D budget. But it's hardly a cost-saving maneuver in the short term.

Also, gotta love the phrasing in the summary "In another win for the company, as the L.A. Times reports, SpaceX also has launched a re-supply mission to the ISS." As though completing the mission that's actually paying the bills was just an added bonus.

You can short the loser side and get an immensely bigger payout if you are right. Options are pennies on the dollar compared to a bet or actual shares.

And in any event, unless you buy in at the IPO, you don't "help" a company or technology by buying their stock since the said stock is owned by some other dude and the sale does not bring a single more dollar to the company; if anything there is administrative overhead for them. The only marginal impact you may have is that by buying or selling you have a tiny influence over the stock price, which may please or displease other shareholders, who can reward or punish executives accordingly.

This is not quite true. Most companies dilute their stock regularly, to compensate management and founders with stock or option grants.

The collection of buyers of those shares set the price for the stock -- which is ultimately being used to provide the company's equity financing.

Now it's true if you bought a share of stock for $1000.... well it's not $1000 that goes directly or indirectly to the company.

But you are trading places with someone who ultimately up the chain bought into their offering.

In the event the buying volume ran out... the stock price could easily fall by a few %. Even a $0.01 price decrease is significant.

So it's not that you aren' "giving" to the company --- it's just that the relative proportions of what you are giving are probably very very small, for a multi-billion$$ company.

Minerva CEO Details His High-Tech Plan To Disrupt Universities

Two years later, there are answers – or the beginnings of answers – to many of the questions observers have raised about the project, on everything from the way the seminars will be organized to how much tuition the San Francisco-based university will charge and how it's gaining accreditation. And in an interview published today, Nelson share more details about how Minerva plans to use technology to improve teaching quality. 'If a student wants football and Greek life and not doing any work for class, they have every single Ivy League university to choose from,' Nelson says. 'That is not what we provide. Similarly, there are faculty who want to do research and get in front of a lecture hall and regurgitate the same lecture they've been giving for 20 years. We have a different model,' based on extensive faculty review of video recordings of the seminars, to make sure students are picking up key concepts. Last month Minerva admitted 45 students to its founding class, and in September it expects to welcome 19 of them to its Nob Hill residence hall."

And we aren't all "sour grapes" about not getting admitted. Minerva offered free tuition to the first class of 45, which seemed like both a good deal, and appropriate given they were still going through "shakedown" (the interview by skype process was more like a high school play than a Broadway performance). There is no doubt that the model, given the time and attention these 45 kids will get, will provide for a stunning class. As does United World College, another free tuition experiment started by Armand Hammer which relies on subsidy to maintain recruiting excellence.

What remains to be seen is whether it succeeds in creating a sustainable economic model. Yes, the USA's universities have probably overinvested their endowments in a "country club" gyms and campus accouterments. But Minerva is "pure play", the equivalent of penny stock. Will the fact that these 45 students are impressive today cause impressive students to pay tuition tomorrow, and will the lack of accouterments generate savings for the student consumer, or be siphoned into the startup costs of Minerva? Since it will probably take 10 years before any of these graduates have a chance to be recognized, they have to either produce evidence of superior education and training, or continue to make it a high value, or have to compete more seriously with a Stanford/Harvard than they had to a $0 tuition. The fact that free software attracts smart users doesn't prove your software will take significant share from Microsoft, and the fact that you get smart students to enroll in free education doesn't signify the universities charging tuition are doomed.

If the impressive kids come out in 4 years and say the Minerva experience was "not ready for prime time" and that they wish they'd gone to college, will Minerva be able to fix the bugs in the software? By the way, my kid's going to a top Canadian university, $6K per year, and is certain to have a recognized degree in 10 years. The strong arguments Minerva makes about the true value of Harvard speak well for Kings and McGill. Twin goes to UWC, btw.

This is where they learn to be Biologists and where they get the value out of the college. No amount of book learning or seminar participation can prepare them for the challenges of actually doing science. Growing living organisms, troubleshooting experimental protocols, interpreting data, and having to write and talk about their results (which are rarely 'clean') gives them the skills to make discoveries which will drive technology forward.
