On #4, that's one thing I noticed too. No mayday. No emergency declared. No contact. The flight just failed to show up.

I can think of three cases where this could be. The first is where the pilots tried to communicate that something was wrong and were unsuccessful, but I would expect that someone might have heard something.

But the other two are more catastrophic. The plane could have disintegrated in the air, giving no time for communications. Midflight breakups are uncommon but they do happen.

Finally it is possible that the pilots for some reason didn't know they were descending and could have crashed into the ocean without ever knowing they weren't at altitude. This apparently happened with AF447 to some extent. It has happened before as well (static ports get clogged, pilots get disoriented at night, etc). In this case the first sign that anything was wrong could have been impact.
> None of these organizations survive without mass acceptances of the stories they intend to run .. whats your point? That these are altruistic organizations? I think not!

Yes, they do. The BBC relies on a license fee, which is not linked to viewing figures.

The Guardian has been loss-making for years, and is not run primarily for profit.
>"Of course, there is also the chance "Satoshi Nakamoto" is a pseudonym, but that raises the question why someone who wishes to remain anonymous would choose such a distinctive name."

I'm so glad you mentioned that quote. Her approach is full of logical non sequiturs like this. They make me want to apply my palm to my face repeatedly.

If someone wants to remain anonymous, then the key action they have to take is not using their real name. After that, it doesn't matter much what pseudonym they choose.

'Satoshi Nakamoto' could have choosen a wholly unique name such as 'Gnafoni Prrrrstlo', which could also be described as extremely distinctive.

But it does not matter, because it is a pseudonym. The exact choice of pseudonym will not seriously impact his efforts to remain anonymous. The reporter suffers from severe logic fail there.

Arguably, the name is not even distinctive. It's only distinctive in the context that he could have called himself 'John Smith'
There's a lot of open data available, depending on what you are looking for. If I had time, I could probably spend it on this SE and earn points, count coup, or whatever. Instead I'm working with a couple of user groups helping local programmers analysts learn how to dig into it. We have a few specific data sets that we use for different types of analysis, demographic, mapping and financial.
Apparently an Italian passenger on the passenger list was in fact not on the plane[1] (and did not buy a ticket, passport was stolen), could be another sign for a terrorist background.

For more information/speculation the airliners thread[2] is also a good source.

SEEKING WORK - Remote (UTC-6 to UTC+2 -- I'm in Europe)

I'm a full stack software developer with 15 years of experience. I've been building Ruby on Rails apps since 2007 (my github id is in the high 200s) and rich clients since 2009. I've helped launch several successful projects, one of which saw 40,000 signups on its first few hours after launch.

I'm only dogmatic about writing simple code. I'll try to push for simpler solutions if they have similar benefits to more complicated ones. It's crucial that I understand the motivation behind each feature request. Expect me to ask "why?" a lot.

I prefer lasting relationships. I'll do my best to earn your trust.

I'm not interested in building apps related to gambling, pornography, or that otherwise try to exploit the worst there is in people.

It affects each person differently though. Personally, I don't notice it at all. It is a bit harder to get up in the morning if it's still pitch-dark outside, but otherwise, I have no SAD-type effects.

Others can barely function without those lamps that are white-balanced to match sunlight and programmed to gradually brighten up in the morning.
Do you use Reverse Polish Notation?

Yes, yes I do
I can think of two likely possibilities. The plane might have disintegrated in midair (that is not necessarily intentional btw, and most midair breakups are bad maintenance), or something could have gone drastically wrong. For example this plane had a previously damaged wing. If something went south, it is possible that the plane could have ended up in a flat spin and crashed.

Another possibility is AIRDU failures leaving the plane to fly into the sea.

Before jumping to conclusions, you really need to read this piece in IEEE spectrum (I promise it isn't computer-generated nonsense): http://spectrum.ieee.org/computing/software/automated-to-dea...
The article makes that point explicitly:

And things got even worse for Quark when, in 2003, you
could get InDesign as part of the newly introduced
Creative Suite Bundle, which as a publisher or graphic
designer, you would have probably bought anyway for
Photoshop and Illustrator. You were basically getting
InDesign for free—it was a Trojan horse in the bundle box,
and I think it really sealed the deal for people on the
fence about the switch.
> why did he admit to being involved in Bitcoin to the first reporter that confronted him

We don't know for sure whether he actually did it. I really doubt everything single thing that lady wrote in that article.
iff you have a schema, and a parser that actually uses it. I've seen a few DTDs but the vast majority of XML documents don't have a schema or even a DTD to follow.

And the vast majority of parsers will not parse anything for you, regardless of schema definitions.

Which effectively puts you in the same place as the JSON string.
Interesting. I may have to look at your exception usage and see if I can emulate the same thing faster with some hooks directly into my VM. No point in running a VM on a VM if I can just implement the hooks directly.

Your code probably isn't what I'm looking for right now. But single stepping and debugging in user-land is exactly what embedded systems need.

I'll keep an eye out for your stuff.

But they could say after 30 minutes or 45 or hell, 60 minutes, "guys, we lost contact with our plane and that happened sixty minutes ago".
I had the same concern of not "taking note of everything", which Powerpoint solves (the teacher just sends you the file).

But the better solution is that you watch the class w/o having to stop paying attention to write, maybe take notes for important stuff, and the class is also recorded and available in your uni website (like http://www.youtube.com/watch?v=F3nbY3hIDLQ ... can't be that expensive to put a camera and a big red button "start recording" in each room. Could even be a student project...)

(Sal Khan also mentions that his nephews preferred him on Youtube than in-person because they could pause and rewind).

(And by the way, I hate that universities that teach technology aren't themselves automatized, with superb intranet, etc...)
To be clear, I'm using "admit" for the sake of argument. He was quoted as saying "I am no longer involved in that and I cannot discuss it..." There's no doubt he said that because he later disputed the meaning. But it seems pretty clear that he thought she was asking about his former contracts and not Bitcoin.

Everyone who buys into this story thinks that the quote is the smoking gun and I just can't see how it even makes sense.

Hey,

This is a project I did a couple of years ago

http://www.electro-tech-online.com/threads/pcb-etching-tank-...

This is another project :

http://www.electro-tech-online.com/threads/first-pcb-stepper...

There was an update on the site, so images are not available there.. Here they are:

http://www.mediafire.com/view/uu4vsqq8e1yq8/PICTURES#6qj25tt...

Bear in mind that this is what my first attempt with PCB design was [PDF] in French, but you can see how ugly it was:

http://docs.com/GH41

I was on the forum chat, and I'd send pictures and they'd help me see, they'd open my eyes and explain things. Why 90° tracks are a no-no, etc.

People are tremendously generous with their time as long as your attitude is okay. I learned orders of magnitude more on the internet than in college, and still do every minute I'm online.
I suspect anonymous will further dox/ equally harass the journalists involved in the original article.
What happens on calling exit() on an Arduino?
That guy must have been getting several people every week asking if he is the Satoshi Nakamoto, and/or trying to blackmail him for his stash.

The deviation from planned flight looks odd to me.

On second thought, looking at other flights, it seems not so odd.
I verified this with a venn diagram.
Are you being serious here? (I cannot tell.) A controller cannot prevent structural damage to the electrodes. I once did research on using lead acid for grid applications. Shallow cycling doesn't save you much. You may double your cycles but if you get just half the energy from each cycle, then the battery's lifetime energy return is not all that dramatically improved.
I'm not so sure. He went by Dorian S. Nakamoto, right? Are we suddenly blackmailing all Nakamotos now?
Great idea. I have a notebook where I write down ideas for companies, things I think about. I think it is a really, really good practice to write it down..

The reason I'm saying that is that human beings have selective memory. They tend to remember things they did the right way, they remember their good ideas, times they were right, etc.

I used to note my ideas that would seem genius.. And then I'd look at them a couple months later and it's humbling. How stupid could I be.

But there is a good thing about this: It taught me a valuable lesson.. It taught me to focus on real needs, and not some fancy thoughts I have at 3AM. Like real needs.

And I know that at an early stage, one needs to let go of critical things and be open and not dismiss ideas, etc.. But it's just that some ideas are plain stupid and I had plenty of those.

I write them down, then cross things. Not a real need, not a problem. Now I'm thinking about an idea that I'd use if it were available. And I'm not the only one.
You are keeping on arguing and deviating. That guy just wanted to compare the feelings in two situations:

- Car is running at 80kmph on empty road and the engine stops working - the drivers waits for it to slow down and parks on the side somewhere and calls 911 (or some other number)

- Plane is flying at 10K feet level and engines stop working. Pilot takes his son's photo from his front pocket and has a close (probably last) look and then maybe starts praying if he is a believer.

Numbers, numbers, facts, facts. If these were to tell us how we should feel in a certain scenario there wouldn't be any branch of philosophy, psychology and all those shit.

It's a simple what-if: What if a plain stops working at high altitude and what if a car stops working at high speed. In case of a plane you brake, turn, up, down, stop - you are done.
I agree it should be usable without a garbage collector, for sure.

But some types of algorithms which are allocation heavy (with dynamically sized parts) will just run much faster with a good collector, and are easier to write that way.

Also I've found that with regions, things get really complicated when structures contain borrows (and not every structure will logically own what it references), and then the structures become parameterized over the lifetimes, which multiply quickly.

For cases like that I'd rather start with a GC reference, and gradually remove GC references where time permits and profiling dictates.

I think Rust can really have the best of both worlds here.

BTW: I did manage to finish a fairly involved analysis program in Rust without using any GC, and I'm really very happy with the results. Being able to GC a few references would have made things easier though.

From your link:

Radar data suggests that the aircraft broke into four pieces while at FL350.

So it seems they saw it disintegrate, whereas MH370 just... disappeared.
The Science of Sample Rates
When it comes to complicated subjects like internals of TCP/IP, they may make more harm than good. Volume 1 of "TCP/IP Illustrated" is, I think, 700 pages long, not without reason. When one writes condensed articles like this it makes sense to stay high-level, because the moment you get into discussing SYN/ACK handshake, you are in danger of leaving large gaps in your explanation or making unreasonable stretches to complete the picture.

On a side note, it's funny to see that most of the paragraphs in the original article end with a link to Wikipedia — as a reader, I can go there myself, what good those articles do to me?
Thanks, my head was already hurting :P
Yeah, the unfortunate thing is after one dies it's "nothing", not even a black hole or vacuum. It's just nothing.
Hear hear, Nashville is a great place to live and work if you are in the tech community. We have a great tech scene, and some big players, like Google, are really starting to take notice. We are one of their inaugural Tech Hub cities, and they have been working with entrepreneurs here for a few years. We have several great initiatives like the Jumpstart Foundry and the Entrepreneur Center that other cities are now emulating. Also, my own company, Populr, was in 500 Startups Batch 7. We have good food, nice people, and cheap living. Come join us :)
Yeah this is exactly where my hate towards Maven configuration comes from, but it's more a testimonial of a bad fit for configuration files than critique towards XML. Java enterprise application configuration has the tendency to be very "expert-friendly", and this is where XML got its bad name from.
That's actually wrong by an order of magnitude, but that's not the point. The fact that individual road accidents claiming a few victims are so common is exactly why it's not news.

1. It could be possible that Satoshi Nakaomoto does not exist or Bitcoin does not exist.

2. Therefore no one has invented Bitcoin or someone has invented Bitcoin.

3. Because each part of the proposition is equally likely we have to infer that we don't know whether Bitcoin was invented.

Works great? Show me some apps please! They all are garbage compared to native imho. Not even really usable, again, in my opinion. I wouldn't recommend Cordova for anything at this point, not because of Cordova per se but rather because of the state of HTML5 on these devices. And I have built a lot of Cordova apps because clients demanded it; now we downright refuse as it's bad for your portfolio to do so. Even if it looks nice it will take weeks (months) to get it working really smooth (stuff you get for free native) and then it breaks suddenly because of some update (especially on Android, but also on iOS, for instance after the 7 update) and you are right back in hell. For every app I have seen which was 'ok' on Cordova you could build it great 3 times native for ANdroid,iOS and WP8 in less time.
I was thinking more about NORAD and the like.
Hey, I understand what you are saying. I loose my nerve beyond control when I see someone hitting a helpless kid or an orphan urchin. In comparison my anger is substantially when I see some douche-bag passing comments or harassing a grown up girl. Blame me for being partial but that's how my emotions work.
> "bitcoin, bitcoin, and vaguely web security stuffs, and bitcoins".

This reminds me a bit of the programming books of old, where the paper was a bit cheap - a similar colour to the background of this H/N page in fact.

I did know who I was replying to :)

There doesn't seem to be an overlap of discussion. Writing down what you know (esp. in your own words) causes reinforcement of long term memories is a well established scientific fact. Ofcource reviewing notes is also critical in strengthening those memories so that you recall precise details rather than vague ideas.

You're talking about not being overwhelmed with taking notes - which again, nobody was claiming is a good thing.

I agree that information like formulas, equations, definitions, etc should definitely be provided without having the student write them down and introduce errors of their own.
> "Of course, there is also the chance "Satoshi Nakamoto" is a pseudonym, but that raises the question why someone who wishes to remain anonymous would choose such a distinctive name."

Satoshi is the main character from Pokemon. Maybe he likes Pokemon. Maybe he hates Pokemon, and wanted to google-bomb the main character. Who knows?

I read the original motion for this, and it's a good read.

The government has some pretty big restrictions on binding regulations from agencies. Restrictions that make a lot of sense when you realize that most law is made by elected officials with constituents, ie representative democracy. Regulations aren't made like that, so you have a lot of rules to prevent abuse.

One of the restrictions is you need to have defined periods for public comment on new regulations. Which the FAA did not do, as I understand things. It just came up with new rules without following the defined regulatory process. If for no other reason then that, the UAV rules were invalid.
The only sensible long-term solution for Linux seems to be to adopt FreeBSD's way of /dev/random operation - block once until enough entropy is gathered and then never block.

This would make sure that distro vendors don't even get a chance to mess initial seeding at boot time. It will also force vendors of embedded or "cloud" distributions (eg. Ubuntu's AWS images) to find a way to pre-seed the images to reduce the initial boot times.

Unfortunately there is such a huge amount of software that depends on this particular difference between /dev/random and /dev/urandom that I don't see the change happening soon.
Thanks for sharing the link. It was a very good read.
The reason is that Hacker News doesn't have an editor, and no formal editorial voice. Instead, HN crowdsources what would be the editor's duties at a traditional publication, to whoever is reading HN at any given moment.

So, right at this moment, the majority of HN readers are into aviation.

The result of this editorial crowdsourcing is something like talking to someone with a personality disorder, as the "tone" of the site shifts without warning. So today we're seeing lots of enthusiasm for aviation stories, but we could see the exact opposite in the near future.

That would mean an opening if there's an opening in the plane, while still above the ground, the plane is done anyway.

I think it's the fire or suffocation (the plane is sealed) if it falls in the water. I really don't know. Go over to reddit, there people there are better chances of an answer.
"how did they actually put enough processing power for all the flight computers in a plane back then?!"

I'm not sure about the SR-71 but not all "computers" (or better, control devices) were digital.

PID controllers are "trivial" in analog electronics (which were already small at that time) as well as other types of controllers.

Several studies on chaotic movement comes from this time, as well as things like this: http://en.wikipedia.org/wiki/Lyapunov_stability
I was reading that at 35,000 feet, if the plane loses power then decompression happens and everyone loses consciousness. This seems like a fairly friendly way to meet the end, could you comment on this?
The best part is that now that it's been posted it has now become impossible to disagree, because attempting to disprove it would actually validate the law.

People keep claiming this, but just as reliably, history keeps proving RMS right. The clarity of vision that he displays in understanding the significance of certain developments in computing well before the rest of us is astounding.

The fact that he approaches things logically and with consistency should only add to his credibility. Instead, he is dismissed as a kook because his personal habits are peculiar by some people's standards. It is a flaw in human nature that enables this to happen, and when it does, it is to our collective detriment.
I agree. I would love to someday be able to build on mobile using games. It would be amazing if you could share a writeup or maybe a hello world starter template on running Gambit on iOS or android. This seems like a lovely project. Congratulations and good luck.
This is also a great way to solve a problem. If everyone in the room is stumped, throw out a stupid solution. If nobody can improve on it, then the last solution wins. Works surprisingly well as most people can critique while finding it hard to create from scratch.
I'm not really an aviation enthusiast. I like planes. But isn't anyone with any interest in things technical an SR71 enthusiast?
Agencies embrace technology to find the enemy within
Reading from /dev/random does not necessarily ensure that /dev/urandom is seeded because it relies on an implementation detail. But reading from /dev/random once and using that numbers to explicitly seed /dev/urandom by writing to it will work without relying on implementation details. That is why I would prefer doing it explicitly by writing to /dev/urandom instead of implicitly by reading from /dev/random although it makes no (big) difference given the current implementation. But this is what you suggested elsewhere anyway.
"Discriminate" because this was obviously intentional prejudicial racism!

Of course it's not malicious. This guy is not good people.
Although funny, your logic is flawed. If you disproved this law globally, it wouldn't be necessary that this particular instance doesn't hold.
