Glider pilot here. I have decent knowledge of aerodynamics, but have never studied large jets in detail. This is my personal theory - essentially what lies behind the words of a few articles I have read over the last few days, but the authors haven't been able to formulate it clearly.

Assuming that the autopilot and fly-by-wire systems were somehow compromized, a full stall in the "Coffin Corner" (Q-corner) would be a very, very serious condition. A stall causes the nose to drop and speed to accumulate. Since the difference between the stalling speed and the never-exceed speed is so small at the altitude in question, this accumulation of speed could easily cause the plane to exceed its critical Mach number, causing supersonic shockwaves around certain parts of the airfoil. In planes not designed for supersonic flight, these shockwaves will eventually cripple the effect of the control surfaces. If the plane is in a nose-down position when it looses effect on its elevator rudder, the plane will overspeed and eventually suffer structural failure (essentially meaning the loss of some critical part) due to flutter (resonance in parts of the airframe) or aerodynamic stresses.

A stall during normal flight conditions doesn't have to be a serious problem, but these weren't normal flight conditions. And the information that we have suggests that certain Airbus models have had problems with their pitot (speed measurement) systems in icing conditions, leading to erroneous speed readouts. The fly-by-wire system, which prevents the pilot from flying the aircraft into stall or overspeed, cannot function correctly without a correct speed measurement. And as I have detailed, a proper stall might be enough to doom the airplane.
I agree. I think this cat and mouse armor is much more pleasing: http://news.ycombinator.com/item?id=649020

Hi, thanks a lot for your review. We are currently working on a credibility score for the users based on how much others value their input. This should create an experts community in each category. Currently you can invite trusted advisors to your own decision pages with special invite code (the UI is only visible to decision creators). The trusted advisors are people who's opinion matter the most. The page will let you toggle between "the crowd" and the advisors via the link on the right of option area.

If you look at this page (http://alpha.crowdmind.com/decision/17_What_Is_The_Best_Java...) I'm the trusted advisor to the decision maker. So our ratings and scores are maintained separately and displayed in the box above.

Right now the site is open to a broad range of people. We are also considering allowing people to import their credibility from their blog, forums they are active in, etc.
Depends on the definition of "soft".

Sometimes you have to be very optimistic (better term: aggressive) regard product features and schedule. This will drive you further and faster towards your goals.

You can't always make all deadlines and keep all promises. And in business (at least in the technology business) nobody expects you to.

If, on the other hand, you make this into a habit -- you will loose trust and customers will be looking elsewhere.

However, I do not necessarily agree with others regarding "long-term" loss of trust. Companies exist to make money and when/if you have a good product that will save them money, you will be able to regain that lost trust.
Other phones -can- do MMS, but it's all so obnoxious no-one really bothers past the occasional pic. iPhone usage patterns suggest they -will- use it. A lot.

And AT&T is simply terrified of what will happen to their network if a few million 3GSs start MMSing pics and video around. More specifically: when they start MMSing non-iPhones.

Tethering is purely and simply a cash grab. They call their package 'unlimited' because truth-in-advertising laws in the US are weak. They charge more to tether because people will pay it. It's no more complex than that.

If you don't want to pay it, there are already apps to turn a hacked iPhone into a wifi access point. And I'm sure a bluetooth sharing app (less power drain) will be right around the corner.
Wouldn't this affect business travel, such as deliveries to restaurants, offices, grocery stores, etc.? I think the primary thing to cut down on is luxury travel, where walking/cycling/public transit it a reasonable alternative - and to do it without hindering business.

I don't know that it would really (it doesn't in Japan), but it seemed like a potential catch.
Never said it didn't. ;)
The easier it is to deploy applications, and the more options available the better. :)
"Just 10% of Twitter users generate more than 90% of the content, a Harvard study of 300,000 users found."

I created something very similar to this about three years ago. As usual, the project went nowhere because I sucked at attracting users and moved on to other things, but I still think the project has merit. So, on the off chance that it will work this time I’ve revived it from the repository and set it up again:

Let me know what you think. Note that everything is three years old and it was hacked together in my spare time, so there are bound to be bugs.

(It used to have its own domain, but I let it expire.)
Although the article didn't cover any specifics of the language, I think PHP has definitely improved. For what it lacks in elegance, it makes up in ease of deployment and scalability. Overall, the improvements made to PHP over the past few years and the upcoming changes in PHP 5.3/6.0 and the variety of excellent frameworks to choose from, make it a very good language to keep in your web development toolkit. It doesn't do everything extremely well, but it does many things well enough.
I like the concept-I think assigning attributes and making people think about rating them will help weed out the idiots you get on places like Yahoo Answers. I do think you need to focus on building a strong, intelligent community for this to work. Also, the layout of the attributes rating box needs to be cleaned up-it's kind of confusing right now.

By the way, I'd be happy to feature Crowdmind on our website, www.usefultools.com, either now or in the future (since you're still working on it).

And the answer is honestly... no. All important news eventually bubbles to the top. Knowing it first doesn't really convey an advantage in the vast majority of cases.

Twitter is more than a news source, however. Many people these days are using it to connect with communities of related professionals, and numerous other uses that I can't be bothered to list out right now.
I play piano, and I kind of have my own style. I can read music, but I generally take a melody, syncopate it, and add my own harmonies and nuances as I play it, by ear. Lately I've been taking guitar tabs, transferring them to the piano, and then tinkering with those.

Seems like people are discovering "hacklogs"; they're published in scene zines and are mostly harmful. The only reason to read them is for schadenfreude; it's usually one hacker taking out another, I don't think the misfortunes of civilians are logged.

For a glimpse into this, and for the most entertaining hacker interview ever conducted, I invite you all to read the phrack interview with The Unix Terrorist:

Searching for just the iPhone UA locks out other mobile WebKit-based browsers that may prefer an iPhone page, such as Android and the Pre. Even if you do want to serve just iPhone users, I think you'd be better off adding a new mime type and serving that.

Also, there's an onorientationchange event on the window object you can listen for, which would be much more efficient than firing a timer every 200ms.

This article (while a bit old) I think does a better job of showing you should go about writing an iPhone-friendly interface with Rails:

I have zero intrest in Music and don't link CS with Math. While I was well above average in math, relative to the average person, I am a far better programmer and consider it a compleatly seperate toppic.

PS: My college DiffEQ teacher got annoyed when I said I had little intrest in getting a masters in Math. I wonder how many programmers have the talent, but lack the intrest.

Space travel is dangerous. It is very likely that at some point a mission such as this would end in tragedy. Turning that into the media circus that is reality television is an awful idea and cheapens the contribution those brave astronauts would be making.

Hard to believe that. If you can grok the logs you probably know how and why the hack works. Plus they're not too informative, for example, few of them show the version of an application under attack, and a good chunk of the time you will see a line like:

~ $./domagic
~ #

Where `domagic` is published script.

There are good texts to read for security, and imo, lamer logs are not exactly at the top of that list. Read the public disclosures, advisories, PoC code; not the private gloating of hackers :-)

I doubt it. I've lived in a fairly expensive city (New York) for about $800 a month. Add in $100 or so a month for extra food, and money for either a bike or a metrocard, and you still have a lifestyle you can pay for with a part-time job.

Agreed, they seem more interesting than the kind of essay questions I got in school.

I really like the feel of the site. Agree with jjs - the sign-up form put me off. I want to get started now, and add info (eg Twitter, company name) later if I choose to do so.

A little more info around the jargon would be appreciated - what's a board, how does this influence project structure etc.

The pricing is confusing, as I don't really understand how you define a board, so I can't judge whether I need 1, 15, 50 or 32,767 boards.

I know you have a link to FMi, but a little info about you guys would go a long way. Make me feel like there are people like me behind this would help me trust you with my project data a little more.

I do like it though - keen to give it a try for my own projects!
My viewpoint depends entirely on what job it is you're doing. As a web developer, it would be incredibly difficult to do my job without the Internet. On the other hand, my partner is a technician in school and constantly battles with teachers trying to browse facebook during lessons when they should be teaching. Clearly the latter can have a direct impact on the quality of the job that person is doing. (That's not to say the Internet hasn't affected the quality of my work at times, but I'm not responsible for educating the next generation.)

I'm a big advocate in giving workers a little bit of freedom. I think they're more likely to feel respected, morale is going to be higher and any decent employee is going to give you better results in the long run.

Of course, being responsible for most of the IT has it's advantages - it would be impossible for my boss to install censoring software without me knowing. What I know about, I can circumvent. ;)
Some would argue that fork-stabbing and listening to punk have roughly the same psychological effects, so you might not be far off there :)

I don't play drums but that's a nice looking set, love the colors.
It is more complicated than that. For example: bombings in Madrids. Would the Arab savages have targeted Spain if it wouldn't have been allied with the US? And what about stupid American ideas like the wars in Iraq and Afganistan? This is all included in beeing "defended". That beeing said, I aknowledge the gist of your argument: Europeans have choosen to be "defended" by the US so they shouldn't complain about the bill.
I play the guitar and from time-to-time I lay down some random midi tracks and generally just mess around with various sequencer software.

The standard is to do that to rise some funds for charity. I don't think you can change that into a business, becuase a band who would change from charity to profit would come of too greedy and self-important. You won't be able to sell that to the cool-kids.
I try to play a guitar, but rarely have I the time lately trying to find the time to learn scheme and tcl/tk at the same time during some occasional readings of tao/zen/scifi literature. I try to keep myself busy, it wears off the time :)
I have to disagree. For one, I think birds flying into plane engines was common knowledge. It's certainly something I've know for as long as I can remember.

And when I got my CS degree we specifically studied accidents where bad software in medical devices killed people. I recall an X-ray machine where the hardware was upgraded and a bunch of software assumptions about when the fuses would blow became wrong. That ended up killing people.

And as someone who has written software for medical instruments I can tell you unit test coverage is part of the contracts we sign.

The coffin corner only played a small part in the accident but that's how accidents always happen. It's always several small things that go wrong together.

A safe airline would not flaunt its safety record, but it's safety practice. Not flying the coffin corner would remove that one part that can go wrong from any future accident scenario.

The safe airline having an accident would not automatically bankrupt it, every other airline has had accident and this one would continue with its safer then average practices.

However, I agree with you this will never happen because as you say the airlines are a crap commodity business. Even Warren Buffet has mentioned how bad a business airlines are for investors.

That's why even though I consider myself a libertarian I want a government mandate to stay out of the coffin corner.

We already have much more complex and difficult to enforce regulations on airlines, this one is simple and would be easy to enforce as we already track all planes on rader closely all of the time.
Let's not split hairs here. Of course you learn something from them, but be honest, aren't you smiling the whole time you read them? They're hacker tabloids; our version of seeing an actor in their fat, pale naked beach body.

I can't believe anybody would take a marker to a lamer log and "dive into it" looking for Knowledge(TM).
I feel much worse about it when car companies or furniture makers try to make one material look like another. Faux wood, faux leather, ect. I consider the steam punk aesthetic to be purely ornamental. That the ornaments may appear at first glance to have some practical purpose doesn't detract from the overall aesthetic for me.
I tried and I'm horrible. I'd really like to be a good musician but I spend my time programming and reading and drawing and writing and not doing music, so I'm not good at that (also I'm naturally awful). I'm a good programmer, but very bad at music.
I would make your "free to try" option a bit more prevalent. I almost left the site before I saw it in that small text on the lower left. It will probably help your bounce rate if you try to get people using it ASAP.

I play primarily drums, though often I putz around on whatever gut-harp is within arm's reach. When I was playing in a band, we were a two-piece grind/death band; we were also another two-piece doing instrumental rock.

you don't understand what makes a plane safe

Agreed. Now if the captain Sully (the guy who landed in the Hudson) says flying out of the coffin corer is safer would you believe him?

Airlines have a huge interest in making their flights safe

Yes, they also have a huge interest in being profitable, they are trying to optimize both.

There's nothing wrong with that, but as a consumer I'd like a bit more choice.

But as other in this thread have pointed out the particular nature of the airline business makes it impossible for that kind of market differentiation to happen. That's known as a market failure.

Hence my desire for a government mandate.

Alternatively, do you think we need any of the current government regulations on airlines?

Thanks for your review. Anything in particular you can point out that we can fix, or is it just the overall design? We initially had Viget Labs to do the design but our direction changed after they delivered. So we had to make the changes ourselves since funding is limited.

I play bassoon in orchestra and piano on my own (though I'm very rusty at the latter).
