The story in more detail at NPR:

[...] "We all knew what the implication was without actually coming out and saying it," a tearful Boisjoly told Zwerdling in 1986. "We all knew if the seals failed the shuttle would blow up."

Armed with the data that described that possibility, Boisjoly and his colleagues argued persistently and vigorously for hours. At first, Thiokol managers agreed with them and formally recommended a launch delay. But NASA officials on a conference call challenged that recommendation.

"I am appalled," said NASA's George Hardy, according to Boisjoly and our other source in the room. "I am appalled by your recommendation."

Another shuttle program manager, Lawrence Mulloy, didn't hide his disdain. "My God, Thiokol," he said. "When do you want me to launch--next April?"

These words and this debate were not known publicly until our interviews with Boisjoly and his colleague. They told us that the NASA pressure caused Thiokol managers to "put their management hats on," as one source told us. They overruled Boisjoly and the other engineers and told NASA to go ahead and launch.

"We thought that if the seals failed the shuttle would never get off the launch pad," Boisjoly told Zwerdling. So, when Challenger lifted off without incident, he and the others watching television screens at Thiokol's Utah plant were relieved.

"And when we were one minute into the launch a friend turned to me and said, 'Oh God. We made it. We made it!'" Boisjoly continued. "Then, a few seconds later, the shuttle blew up. And we all knew exactly what happened."

"People are sure the iOS browser is great because they never actually use it. Instead they use apps."

I agree with some of your points, but as far as I'm aware every article I've seen on the subject points to iOS devices accounting for a large majority of mobile web browsing, so clearly a lot people don't think it sucks.

My personal experience using the Galaxy Nexus default browser for the last 2 months has been:

1. A bit more overall studdering when scrolling webpages than my iPhone. Nothing dramatic, but noticeable.

2. Double tap to zoom on paragraphs of text is really hit or miss. Half the time it zooms in incorrectly cutting off the edges of the text.

3. Embedded videos on a lot of websites refuse to play and prompt me to install Flash. On iOS they just serve up the html5 version and pay.

Overall I never found the default browser to be absolutely terrible, but I didn't love it either. Chrome beta has been a big step up in the last 24hrs already and am hoping this is where Google is set to put it's energy.
This is insightful especially since we have thought about this problem and had not come up with a solution. I am assuming all the icons will be unique though, else it may lead to a lot of confusion. Also, I believe people choose icons that they best identify with and if it is not unique their association with the icon may not be as strong.

Another thing I have experimented with is if you can upload a picture and create a hand drawn painting / image like Chris Dixon's or Fred Wilson's image which I think are brilliant in creating a brand and identity.
I'm presenting two possibilities:

1. There's an efficient market, and CEO pay reflects the extra value they create. In other words, a $100 million CEO is worth $50 million more than a $50 million CEO, so your economic outcome is the same regardless of which one you hire--except that larger companies will extract more value out of a given level of managerial talent, since they can amortize it over more underlings/revenue/whatever.

or

2. CEO pay and company performance are totally random. But for that to be the case, you'd have to deny that there's any such thing as being able to identify and pay for a talented CEO. Maybe! But every time I've interacted with large company CEOs, I've noticed that they tend to be very bright, and they work extremely hard. People who are in the 10th percentile of public company CEOs--the kinds of people who bankrupt companies--still seem to be in about the 90th percentile of smarts and energy.

I don't know of another theory that could explain the data as presented. Either the process is random, or it selects for people with certain valuable skills. If the system tends to promote skilled people, you'd expect the companies they run to have a higher return. Unless, of course, they capture that value for themselves.

If the publishing industry has anyone with half a brain working for them, they should see themselves going the way of the music industry. They need to innovate fast. Open source books are only part of the problem (and by problem, I mean only their problem). It is becoming easier and easier to find torrents to download full color versions of many of the most popular textbooks.

My two years on a Nexus One say otherwise.

What?

I spend more time in Safari than the latter 7 combined.
Have you read any of Stallman's more political and moral manifestos?
Yeah. As I was watching the video, I kept thinking "why not just use a horse?".

But I think it's safe to say that this isn't going to be used just for carrying stuff. They're aiming to ultimately weaponize it and use the new tech to create other cool stuff.
The big E's one advantage is it's already in space.

Ask HN: Running OS X on pc through Virtualization
Hi Hackers

I just got a new laptop from HP with a lot of power and I would then hear if anybody have had success with running OS X in WMware or Parrells?

I would really like to try OSX, both for fun but also for trying to learn another OS.

I have seen different guides on google, but many of them are very old.. :/

Thanks for the help, much appreciated!

Just wondering: how do you get into MIT at 16, and is it worth it? I mean would you be missing out as a 16 year old at MIT (or any other university) because your peers are into other things than you, or is it an overall net plus?

I assume that it is not some inherited genius that enables kids to get into university, but some unique "strategy". Of course I could be wrong. I also assume it would be doable without ruining the childhood, that is, the kid should be naturally excited about science and stuff, not forced into it.

> Why would they even care?

I bet they would complain loudly. At least, they would before demanding the same from W8 manufacturers.

> MS has made it mandatory on x86 devices to have a open bootloader.

Unless I misread, they allowed x86 manufacturers to have open-able bootloaders and have the W8 approval seal. IIRC, no non-UEFI boxes will receive the seal.

> ARM desktops from Dell

Who said ARM desktops? I asked how would you feel if your current x86 desktop had a locked bootloader.
When it comes to retro-futurism, I'm having a hard time finding a more uncannily accurate past prediction than this one by Andy Warhol: "In the future, everyone will be world-famous for 15 minutes."
"but it's not necessarily a path to success."

Nothing is an absolute guarantee. No matter what the path.

This is a ridiculous statement. You attempt to defend "business as success" by arguing success is never guaranteed. While being a silly argument, more importantly you seem to completely miss what your parent was talking about- he was not discussing how your business might not be successful, but that for many people, success in business != success in life. In the same way that money != happy.
It's interesting that there doesn't seem to be any country restrictions - this is usually the type of thing that is USA only.

Because they have no need to declare everything they base a decision on, and the decisions they make will often be made at face-value without consideration of any other information that might offer a more rounded view.
I think there's a semantic hangup here, what you're describing is accurate, but it probably "better" explained (in the case of something like the popular wordpress caching plugins) as "compiling" your content to flat HTML which is saved on disk. The web server/CDN can then "cache" that file.
I wait for the day one of those "space" experiments by some high-school student (and his parents) ends up crashing a jet engine or lands on a windshield of a van going 80 miles/hour.

It's all fun until reality and hits you right in the face and you pay for your YouTube video for the rest of your life. Is it likely to happen? No, but that wont save you afterwards.

Predict illness from patient history to win $3M
I just received my copy of "Collective Intelligence" in the mail this morning, and immediately sat down and starting reading. I've been reading for the past several hours, non-stop. It's that good. Perhaps the best part is the chapter at the end of the book that neatly and concisely sums up all the major ML algorithms: neural networks, SVM, kNN, k-means, decision trees, Bayesian classifiers, etc. etc. This chapter alone is worth the price of the book. I only wish it were longer (and it's not a short book).

I think you have to look at the trade-offs of scale. McDonald's serves 58 million people EACH DAY (http://understandingbignumbers.com/how-many-people-does-mcdo...) at extremely low cost. How does that affect the quality of the food and the experience?

If Khan's method scaled (at lower cost) without sacrificing other features of high quality face-to-face instruction, then I would expect people who pay private school tuition (K-12) to push their schools to implement such an approach in order to lower tuition.

But there's a reason why the elite pay $30K/year for K-12 private schools: Small classes, strong student-faculty relationships, high-quality facilities, and the exceptional educational experience that comes along with those features that cannot be replicated on a large scale.
I have seen news reports of studies done by public-health researchers who worry about computer keyboards and phones after measurements showed surprisingly high numbers germs on these items.

It might be that the researchers were worried only about germs that can survive for only a few days or cannot survive the type of cleaning achievable without completely disassembling the phone, but it is not obvious to me that that is the case. For example, one hears about these biofilms that allow germs to survive for very long times.

What are your reasons for believing that just being in the same room as other people exposes a person to more germs?
Sure. However there are two parts in this idea:
1. The idea of adding very simple metadata to links (to enrich the web)..
2. The usage of this metadata. Eg. like Flinkr does.

The Flinkr implementation simply reformats the data to do a search that it thinks is most relevant.
Eg.

"wiki:george w bush" will redirect you to a wikipedia search.
"movie:the matrix" will do a search on imdb.
"book:lotr" will use the Amazon API and redirect you to the result.

Other searches use 'Google I'm Feeling Lucky'..
SecondLife does this.

You have to use a real name, address and credit card to register an account. But in-world, no one knows who you are and there is no practical way for anyone to find your real identity. And for misbehavior (griefing or harassment), they can block you (by IP I guess) for days, weeks, or forever.

Oh---I did miss your point then, but I think the text/photo distinction would actually be somewhat easier for them to defend than a content/porn distinction; as I understand it, porn is content, as a matter of very well-settled caselaw.
Good analysis. It's great that to be reminded that for as awesome as GrubWithUs seems at first glance, there are always ways it can be improved.
I was looking forward to this until I found out it was a comedy instead of a serious b-movie.

I agree; I'd imagine the act of violent/abusive trolling is a clear symptom of one of a number of personality disorders.

With iphone every carrier now claims they gained new customers or kept more of existing, they all suffer in profits and they all hope to gain back in a couple of years. and here comes removal of the unlimited data plans, the increase of price for devices and plans. Apple is happy, carriers think they ll be happy, and iphone buyers are the happiest. Is there something wrong in this picture, or is this a non-zero sum game where mobile growth lures more profits from elsewhere?

The Curious Vaporization Of Jesta Labs, A $15 Million Startup Incubator
Top end MTB bikes are of very high quality, a joy to ride. But they depreciate sometimes by 50% in a year: new models are out, lighter, stronger, better-handling and everyone wants to upgrade.

be careful. Some high-end MTB brands depreciate more than others, which is the exact point this article is promoting about phones.
We've tried "Don't fee the trolls" for years: it has only lead to them becoming more vicious and egging each other on. It means the only thing they hear is how awesome they are from their friends.

It is time to engage: people with patience could engage them in good faith: instead of asking "how do you justify it?" ask "what is your life like that you feel the need to do this?" There are a number of violence-intervention programs that could be adapted.
Alternatively, we can drive them to ever-greater heights of rage by armchair psychoanalyzing them and bombarding them with ridicule: laughing at fear can make it go away. We could shun them, alienate them, mock them and otherwise make trolling unpleasant to engage in. Right now the incentive to troll is there and there is no disincentive: we need to create one.
In real life, the disincentive is that someone will take a fully-justified swing at the troll or they will be arrested for harassment, stalking and verbal assault. We need to enforce the internet-equivalent of getting punched in the face, since the government doesn't appear to enforce laws against harassment and assault online.

> Isn't that exactly what would happen if you wrote an interpreter in any language with a tracing VM (ie. LuaJIT)?

No. Say you have an interpreter loop written as a switch:

while(has_bytecodes) {
bc = next_bytecode()
switch(bc) {
case OP_ADD: ...
}
}

(Assume for the sake of argument you've got a Lua version and a Python version of the above). In both cases, the loop gets compiled to bytecodes. Before the JIT, you've got two levels of interpretation (call them L0 and L1). The first level of interpretation executes the second level of interpretation, written in Lua or Python bytecode, which interprets your custom bytecode.

When LuaJIT JIT's the process, it will generate native code to replace L0 and directly implement L1. The end result is the same as if you had written your interpreter in C and directly compiled it to native code.

When PyPy JIT's the process, it will use your hints to collapse both levels of interpretation. It will replace both L0 and L1 with native code that implements the bytecode being interpreted.
You are wrong. Html5 for Youtube is still an opt-in trial, unless you are on a platform without flash.

As for related sites, while most I frequent seem to keep their files in .mp4 format rather than .flv the players are all flash based. Probably because it's easier to serve ads.

I can't address the part about my assertions being unfounded, but you can replace "high marginal tax rates" with "lower levels of executive compensation" without affecting the argument.

A safe 777 is hard to build, but a safe orbiter is an order of magnitude harder, with respect to the range of velocity, temperature, and pressure that the vehicle endures.

It's not a totally fair comparison to say "Boeing can do it, why can't NASA and their contractors"

With current technology, it seems obvious that if we want to (further) develop manned spaceflight, we should launch unmanned orbiters with crash-test dummies and telepresence surrogates, and keep doing so until we've established a safety record.

jit_merge_point isn't an optimization. It tells the PyPy JIT how to separate the parts of the trace that are part of your interpreter loop and the parts of the trace that are implementation of each bytecode.
I was hoping to see that they would just drop the entire database, and then implement hashing from here on out. Otherwise, the apology feels sincere and I appreciate it.

Glad to hear it's in the past. I added more after some thought on how the usual management process work.
I think I disagree. To me, good science fiction proposes some future technology, then explores what the ramifications are for society and/or individuals. It is relevant to us now, because it explores how our lives would be different if something new was introduced.

A great example is a short story by Asimov about someone who creates a television that can look into the past. The government in the story has known for a long time that such a thing was possible, but kept it secret because of a simple unintended consequence: the elimination of personal privacy. If you can look into the arbitrary past, then you can look into anyone's past of 5 seconds ago. The consequences are society-shifting.
