A quick translation: "pricing not on the front page, because contact us" -> "we have an enterprise sales model, which means that if you won't pay six figure prices, forget you ever saw this product".

Not always literally true, but a good rule of thumb; you can't really sell $100-$1000 products that way, the cost/time of salespeople doesn't work out in that case.
I appreciate that radar only works above a certain altitude, but can someone explain to me why a vehicle worth > $200m doesn't have a GPS unit broadcasting over longwave radio,satellite connection or some other remote communication means. I feel like I'm missing something fundamental.
"We only make money when your community is successful" scares me; would this mean a forum like I own (with 500K pageviews / month) would end up paying out of all kinds of unwanted orifices.

Glancing over the comparison, I'm noticing one possible discrepancy: "Default legal documents to reduce your liability" are available in pretty much all online services like these, the terms & conditions and the like. I know that vBulletin also has forms for registration of minors and the like. I'm also pretty sure those terms & conditions are tl;dr documents of legalese nobody bothers to read though.

The software itself... it has pagination, woot. With the minimalistic style and html (compared to vB / IVF) I think you could do with infinite scrolling (optional depending on device, it's still kinda sucky on mobile) or something clever like that.

I want to make a remark about the apparent lack of functionality, but that would be unfair; I'm a vB user, the only things I use on there are just reading and writing posts. vB forums like mine often do have a lot of user post customization though; postbits with all kinds of information, personalized (and larger) avatars, tl;dr signatures, custom post styles, that kinda thing. It may sound trivial, but it's a form of self-expression a lot of our users appreciate. See also: Tumblr's user's eyesore styles.

The events page is neat, and as far as I know not something the competitors have in that form - looks like an unique selling point to me. Code / image / video embedding is also neat.

This is a confusion created by us that was not intentional and the designer is looking to fix very very soon by gutting that part of the page.

The compare + pricing is comparing our offering "Microcosm" to our competitor offerings. It isn't comparing various packages we offer.

We only have one plan, it includes everything.

Though other founders suggest we invent another couple of plans to hit the Goldilocks "too hot, too cold, just about right" method of selling.

And yes, Vanilla is strangely priced considering the market, but they do have some compelling features too... everyone draws up their comparison tables to favour themselves. I actually wanted to promote the fact that we don't support signature at all as a positive.
Dude, planes can explode in the air because their windows are the wrong shape. That lesson got learned the hard way. Engines can fall off because of damaged mountings. Engine turbine disks can explode and take all control systems with them. Gears can jam and elevators stuck causing planes to nosedive.

You are talking about a highly pressurized canister of air travelling at the better part of the speed of sound way up in the sky, and it must be made as light as possible. It's a marvel they are as safe as they are.

> Remember, you're far, far more likely to be injured or killed driving a car than taking a plane. It's one of - if not the - safest form of transport out there.

Right, and this is an indication of how safe one can make things even given inherent risks in the technology. It's worth remembering how much we devote to this task. And there are plenty of near-misses that are just mind-boggling, like BA-9, for example, where the 747 flew through the ash cloud of a volcano and lost all four engines as well as rendered its windshield more or less opaque. And yet they still landed safely.

Aircraft are amazingly safe as they currently are. However structurally, there isn't a lot of room for redundency.

DO NOT offer equity right away. Marketing/Sales guys are good at selling themselves, but bringing in revenue is tough. Not everyone can do it consistently.

Let them have a stake in the sales (say 10-15%) and make sure it's transparent that sales are coming through him/his efforts. Assume you'll be hiring more on these kind of terms.

Once you see something rolling, you can offer some equity accordingly.

You'll know how confident he is when you tell him there's no salary, only %age of sales he brings in.

Well, it does matter - if 100 stolen BTC go into a wallet that has 900 BTC already, and then 1000 deals of 1BTC go out to different wallets... then you blacklist and seize all 1000 outgoing BTC or some arbitrary 100 BTC or some specific (how) 100 BTC?
Seems unlikely to me. There's not a lot of tensions around that and shooting down a flight at 35000 ft would pretty much require a nation to be behind it.
there is a 250-400 km range for FlightRadar, it does not cover oceans very well.

http://www.flightradar24.com/how-it-works
"Flightradar24 has a network of more than 3,000 ADS-B receivers around the world that receives plane and flight information from aircraft with ADS-B transponders and sends this information to our servers. Due to the high frequency used (1090 MHz) the coverage from each receiver is limited to about 250-400 km (150-250 miles) in all directions depending on location. The farther away from the receiver an aircraft is flying, the higher it must fly to be covered by the receiver. The distance limit makes it very hard to get ADS-B coverage over oceans."
Hahaha, awesome. This is what makes me come back to the hn community time and time again. Thanks for the update.
Most universities I've been to have 9 black/white-boards in a lecture hall. No risk of erasing what was just written because you run out of space.

In case you haven't seen this configuration, the boards are mounted on rails that allow them to slide up above each other when you're done with one, with three of these set ups next to each other giving you a 3x3 grid of blackboards. Smaller lecture rooms have a 2x2 grid which lasts quite long also.

> Does anyone know if there's a possibility for survivors?

I doubt it. No emergency transponder recorded. No mayday heard. It was at night. This suggests one of two things to my mind:

1. catastrophic failure with no real time to adjust, like an inflight breakup, or

2. A lack of knowledge that the flight was flying into the ocean (AF447 comes to mind there but there are other cases).

Ditching a commercial aircraft in the ocean is not easy. It's going to be rediculously difficult at night, and right now there is no indication that the pilot was even trying to go for an emergency landing.

I wish I could be hopeful, but it really doesn't look good.
I'm not even pro bitcoin(pretty neutral really) but there is so many things wrong with this.

Basically everywhere the author says "as far as I can tell" they are wrong.

Lost Wallet: If you lose your wallet with your cash in it then your cash is gone. So you don't carry all your cash at one time in one spot. Same with bitcoin.

Central Hubs Vanish: Confusing exchanges with the block chain.

Evaporation: bitcoin mining will always be needed to verify transactions, and the increasing price doesn't matter since people will just use smaller pieces of bitcoin as it does so.

Laundering: Possible through the existing banking system as well(see HSBC) silk road had $3.5 million in bitcoin because they were paid in bitcoin.

Anonymity: cash is indeed great for it but it's difficult to use across long distances.
If any scenario that 'blacklists' some bitcoins is implemented (IMHO it won't, but if we're discussing it..), then any bitcoins 'tumbled together' with blacklisted bitcoins would be blacklisted as well.

Which would mean that either people would stop using tumbling services (since the process would turn 'good' bitcoins into 'tainted' bitcoins as soon as a single participant wanted to anonymize stolen BTC), or tumbling services would disallow tumbling any blacklisted bitcoins, or both.
Seconded. I recently evaluated quite a few Scheme implementations for a very simple web scraping project and found Chicken to be both fast and great with its packages. chicken-install feels almost like pip or npm and it works really well. The packages are many and most of them are nicely documented. If you need a Scheme with compile-to-C capability and a bunch of batteries included then Chicken Scheme is the way to go.

>extraordinary claims require extraordinary proof, and this is not good enough.

Indeed, it is far from enough. No respectable media organization would have published such a tenuous story.

It's nice to have apparent confirmation from the police, but what are they confirming? They are confirming that the quotes were accurate. But Dorian Nakamoto has already confirmed that he was quoted accurately. He said that he misunderstood her and she apparently misunderstood him, and that seems entirely possible.

Her entire story relies on the confused 'admission' from Dorian Nakamoto during a few minutes interaction. She effectively ignores evidence that does not support her claim, such as the inexplicably huge difference in public writing styles of D Nakamoto and S Nakamoto.

What this new revelation does show, if you read the full reports of it, is that the reporter prompted the critical quote from the police officer, which opens her story, by first feeding him the suggestion that this old man was the creator of Bitcoin.
I suppose it comes down to the amount of investment available. Amazon can pour resources into security, monitoring and have a large staff actively keeping an eye on such things. They're signed off for PCI compliance Level 1[0] (Any service provider that stores, processes and/or transmits over 300,000 transactions annually) which helps isolate you from a lot of costs around getting your dedicated hardware audited yourself.

"I'd be hard pressed to find a reason not to go this route at least once in your life. I know the material pretty well but I still re-read Stevens books every few years just because it is so good."

Then again, that's a lot of effort to spend on something that the vast majority of us don't need to know in much detail. The main reasons for knowing all the details are

- to write a new networking stack, or working on an existing one;

- to write or maintain server software or routers or caches or other software directly involved in networking;

- to break or exploit existing software.

(obviously 'because it's interesting' is a valid, but not practical reason to know)

It's about universal chemistry rules.

For example, it's very difficult to make a family of many complex stable molecules without carbon, so the "organic" chemistry of other words is probably based in carbon as our organic chemistry. Moreover, organic chemistry actually means "carbon based" rather than "life based". Many of these carbon bases molecules are built also by inorganic means in other words and in deep space. It's possible to make some complex molecules with boron and nitrogen, but most of them are not stable enough to bet your life on them.

Other main detail is that you need some very energetic reactions, like combining the hydrogen in a molecule with oxygen to produce water. (The smaller example is CH4 + 2O2 -> CO2 + 2H2O, but methane is not easy to store, so most of the time earths life depend on the combustion of more complex molecules like sugars of fatty acids.) It's a matter using oxidations and reductions to obtain energy in a weight efficient way. Oxygen is easy to distribute, big organic molecules are easy to store and use in chemical reactions in controlled setting.

So if you want to find whales, look for oxygen. In Earth's atmosphere is easy to find some strange non equilibrium mixing of oxygen from plants and methane from cows. (In any case, most of the oxygen and methane on Earth is probably produced by bacteria.) If you are really pessimistic, look for any anomalies in the spectrum.

I checked Wikipedia http://en.wikipedia.org/wiki/Europa_(moon)#Potential_for_ext... . The article says that there are oxygen molecules in Europa! Mostly produced by the decomposition of water by the Sun's radiation. Someone estimated that the concentration of oxygen in water is enough to support fish equivalents, but it's an estimation not a measurement, and estimation are usually optimistic.
I just read the chapter about fixed point combinator (aka Y). It's great, not only for kids.

I tried reading the book a few years ago, I remember being irritated by the QA style it uses and dumping it because of it. On my second attempt I realized that it's only irritating if you know the answers very well and skipped to the chapter I didn't have so much confidence in understanding. And it was very pleasant experience, especially when I stopped to think a little before reading the answers. It felt like I was having fun.

So I'd advise to give a book a go, even if you are confident in your Scheme and FP skills. Just skip the parts which seem too obvious to you and get to the interesting stuff, you won't be disappointed.

Now it's time for The Seasoned Schemer, I guess :)
That's not really how we use probability, how about we start by considering the most likely scenario and, if needed, progress to the "non-zero" probability events.
I understand relation to FP. I even think of having lazy-evaluated infinite sequences in my system :)

BTW, great thanks for the paper, it seems to be closely related to what I'm working on.
You're talking 10-15 years earlier than the time at hand (early 2000s). By then computers were already pretty cheap.
I don't know about avionics much either, but I'm wondering why, even at the time of AF447 if the planes do broadcast information about their current position (including altitude and speed), there seems to be no obvious "Your plane is dropping from the sky!" warning generated by any systems and remotely sent. Even if it's not a continuous stream of data, planes don't fall infinitely fast; it took a few minutes for AF447 to reach sea level.
Looks like they did a pretty good job:

I wouldn't rule out local adverse weather or environmental conditions that would contribute both to downing a plane and rapid loss of communication...
I'm in Toronto, working as a rails developer. Last year, while doing some freelancing on odesk, I saw a CTO of a startup get the minimum viable product built by partitioning the job out to a few different odesk workers. He spent about $10k for 600 hours of work - the startup was an ecommerce site that had a gift recommender based on the answers the customer provided.

You get what you pay for however, so while the site works, it's pretty ugly (needs way better design). Also, his main contractors were barely fluent in english - so communication was always bit tricky.

BTW, feel free to email me since I'm in the same town.

Building something for yourself
IMO, that's the most likely scenario. This highly advanced airplane was in clear weather in a spot where any distress signals it sent would have been received. The plane itself can send automated signals even if the pilots were incapacitated. No signals went out, and according to media reports, the plane simply "vanished" from radar (i.e. the data didn't indicate the plane descending before it disappeared).

All of the data indicates a mid-air explosion. There are some possible causes of such an explosion that are not terrorism related, such as mislabeled/improperly stored explosive cargo, but IMO those causes are at least as likely as terrorism in this case. It will be interesting to see if any groups come forward claiming responsibility.
I know, but as nobody looked at it back then and i think it is relevant again this week i just posted it a second time. Its a really interesting read, so i hope people dont mind.
Not really, no. Immediately after that statement it says "When contacted, Malaysia Airlines declined to confirm or deny the reports", and nor has it been confirmed in the six hours of updates to that story since.

The A380 does this. If you watch the Air Crash Investigations episode (also known as "Mayday) Season 13 Episode 10 - it talks about the Qantas A380 that had an engine explosion.

All the data from the plane was being relayed back to Qantas HQ - and the engineers at Qantas HQ were able to see in realtime all the issues facing the plane.

Ironically there were so many issues, they actually initally thought the system was faulty (i.e. there were too many faults, so the fault must be the alert system).
Images are going to be a problem for the social buttons, too. There should definitely be alt attributes providing reasonable fallback text.
Is there no good serif monospaced (preferably bitmap) font?
Of course I may be proven wrong, but I feel that it is quite premature to make such an assumption. A plane can rapidly disappear from radar for a number of reasons: not including your suggestions of terrorism or explosive payload.

A prominent example:

Thanks. I didn't think of this before. It certainly looks like the way to go.
Governments have developed so much surveillance technology that they can easily invade the privacy of many citizens, yet tracking the exact whereabouts of planes flying in the sky - something that for scheduled, commercial flights whose routes should very much be publicly known information - still seems out of reach? I find that fact a little unsettling.
They are cool. A bunch of them were stationed at an Air National Guard base near my house and they would frequently fly overhead. Eventually they moved elsewhere; which is just as well. They are noisy too.
Yes, your words are quite encouraging. I'll give it a try and see how it goes.

I am not a people person and never been to that line (marketing, hiring) so it feels a bit different and new altogether. At some point, this has to be done, so why not now.
