Full Disclosure: I work for a competitor of theirs as an embedded engineer.

Question for any bug labs people. How are you guys running the alert code? I assume it's something long the lines of a node sandbox that just runs the bit of JS, I've only looked into that stuff breifly. I was also looking at using really light weight interpreter called Duktape for a personal project. It has got a really similar C interface to Lua, but that ended up being way too much work and I abandoned it. I also recently found an erlang js interpreter that looked really interesting too, can't remember what it was called but it was from one of the erlang nosql databases, they used it for doing map reduce.

Also, why did you guys decide to go with chunking for the push over something like long polling or websockets? I assume the websockets was because of device code complexity, but longpolling seems more standard/less of a hack to me.

I always love seeing how others implement these kinds of things.
Hey! I wrote this. Thanks for posting to HN. Glad to discuss here.
Any sources? On the first look that doesn't seem even remotely possible.
Planes are going to become very expensive in the next 30-40 years, unless we come up with a cheap alternative to the energy density of petroleum. One advantage of trains is that they don't have to carry their fuel.
Forgive me if this is forward, but are you guys hiring? I'm in no way a physicist, but I do know a few with strong experimental backgrounds (mostly in nuclear), and I try to keep my ear to the ground for intriguing job opportunities for my friends.
I don't really think that's the future. The most comfortable commute I ever had was the Metro North into Manhattan from Westchester. Can't beat having a bathroom on your commute. Can't beat the physics of rail having lower friction than car tires (especially at higher speeds). In a place like Manhattan, I see self driving cars as a replacement for taxis, not trains. Outside of Manhattan, well who cares about those places?
The NIF has never reached "break even" in the sense that most people might understand that phrase. Orders of magnitude more energy went into the system than could have been extracted from the resultant fusion reactions. However, post-analysis of a bunch of shots showed approximately two where, if you accept a model for the amount of laser energy that was incident on the target, somewhat more than that amount of energy was produced from nuclear fusion. Several other shots in the same series, under the same conditions, failed to produce this "break-even" energy. This is all in the actual papers, not, of course, in LLNL's press releases.
I also find this fascinating, but have never seen any good technical discussion of it. Do you have any pointers?
> people have more respect for those who present themselves well

If presenting yourself well means driving a luxury car, or having an expensive home, then no, I don't respect these people more than others. There are no such 'rules of society' except for materialistic people.
I know how you feel.

I've worked at a couple of startups, two groups at Apple, two groups at Google and now at Twitter. I've learned two things chasing a feeling of fulfillment, like you seem to be:

1. You can't expect your job to give you the all of the fulfillment you need.

2. The most fulfilling work is the kind of work that's just challenging enough, but not too challenging--http://en.wikipedia.org/wiki/Flow_(psychology)
I think the problem is not national will, but cost. In my experience (in Korea, and Europe) is that high speed rail is heavily subsidized, but still not competitive with air travel.
Thousands Of People Oblivious That Anyone Can Access Their Computers
Unfortunately, as we've discovered from the whole net neutrality debate -- netflix has offered these boxes for free to all major ISP's... yet the Big5 ISP's have all turned them down.
I don't think mobile fusion reactors are what they're going for. And if you're looking to reduce global carbon emissions try walking, biking or using public transportation. It's true electric cars don't emit carbon the way a fuel based car does, but the production and maintenance of an electric vehicle certainly does.
My favorite proofreading tip is to have the computer read writing back to me. The computer won't skim over sections. It will explicitly read every word. Your ears will pick up things that your eyes won’t. Grammar issues such as messed-up tenses become super-obvious when you do this. Obviously this doesn't always help with misspellings and it rarely helps with punctuation.

(FYI, on a Mac it is easy to setup a key command to read back selected text in System Preferences > Dictation & Speech > Text to Speech)

> Only when being installed. When operating, the true cost per passenger mile is much lower than for interstate highways and cars. It's best to avoid misleading economic comparisons.

Installation costs would be included in your cost per passenger per mile (though likely amortized over the usable lifetime or augmented with maintenance/upgrade costs). But overall I agree with you that perhaps the cost per passenger per mile works out favorably for high speed rail for trips of a certain length (I address that in a different point). I am just pointing out factors the author glossed over.

> False choice. Cities have sophisticated, multi-level rail and surface mass transit systems for a reason -- they make economic sense.

What false choice? I am pointing out that traffic around cities is NOT predominately inter-state traffic but local commuter traffic. I agree that city transit can be very cost effective and eliminate local road congestion. However this is all ancillary to the high speed rail argument. High Speed rail is not used for local commuter traffic which I am characterizing as 50 miles or less. High speed rail (and the national funding associated with it) will not solve local city congestion.

> I have to ask -- who are you working for? Your arguments are all paper-thin, easily torn to pieces. Roads and cars are democratic? More democratic than a seat in mass transit?

I work for a software company as a developer :) So clearly I am the authority on high speed rail. I disagree that my arguments are "paper-thin" and easily torn to pieces. As far as my democratic statement I will expound as it was used in a context that your quote eliminated. High Speed rail is useful for longer distance travel where speed (time) matters. The frequent (daily/weekly) users of this system are skewed towards the very wealthy who have commutes/business travel that travel distances where high speed rail is cost effective. Thus using federal subsidies (which are pooled for the entire population) to fund a service for a fraction of the population is a hard sell in a democratic government. Roads are an easier sell since most citizens own (or could own) a car and have travel needs that fall within the radius where car (or local mass transit) is cost effective.
You had luck on your side though. Not everyone does.
Well, I don't know much about the subject, but the way I've understood it there's ITER and then there are a couple other reactor projects. Everyone except ITER is violating some kind of popularly held belief among physicists - they could be cheaper and better, but it's far from certain that they'll work at all. This just looks like another one of those.
"Because the citizens have been indoctrinated to not believe in public works and public goods."

Really? By whom? Where?

Trust in government hasn't collapsed due to a sudden lack of people advocating government solutions for everything in the past 50 years. In a nutshell, it's collapsed due to government not being able to deliver on a great deal of what it promises. It's simply irrational for the public to pretend that the government has some sort of spotless track record over the past 50 years.

Given how many of those failed promises have been infrastructure projects themselves, it would bode poorly for trying to fix this distrust with yet another one.

And remember, if you're inclined to start making excuses for why the public may not trust the government, you simply end up explaining why the public doesn't trust the government, it doesn't make the mistrust go away. Consider that a list of problems to be attacked before the government has the moral capital to spend again on such infrastructure projects. (One rather potent way of looking at the government's trust problems is its repeated willingness by government officials to spend that trust without putting a lot of effort into depositing into that account.)
Bitcoin is brand new and it has to have a growth process because of its nature, unlike state-sponsored currencies like the Euro that can just be "rolled out." So you can't fairly compare it to mature currencies, even though it is a currency.
>but an airplane ride from A to B is cheaper than an equivalent car journey for most trips.

Anyone with a family knows this blatantly false. Family of four form SFO to SAN ~$700 - 1K on a plane. Gas at 30mpg is $132 round trip. Add in a $100 each way if you are renting a car for one day, one direction, and you are barely at half the cost of the cheapest flight.
The risk of #3 is that they don't create fusion but they do develop a machine that can emit streams of hot plasma which is then turned into the Navy's weapon of choice for close weapons support on carrier battle groups.

That said, I am looking forward to at least one of the fusion efforts bearing fruit. I'm something of an optimist here but I expect a durable solution to the 'energy problem' to emerge from our developing understanding of both quantum mechanics and particle physics. I am also cognizant of the fact that it also raises the bar on both good and bad things that humans can do. The tricky parts are in the transitions, pre and post event.
Out of curiosity, how long have you used OS X?
>False choice. Cities have sophisticated, multi-level rail and surface mass transit systems for a reason -- they make economic sense.

This is about high speed rail.
They at least used to have something on their SuperHD page that would tell you whether your ISP participated ("Sorry, you can't view SuperHD content because your ISP has not opted in to our OpenConnect program"), but I think since they opened that up, there's no obvious list.

This article fails my smell test. The adolescent vocabulary doesn't correlate with the otherwise polished writing style and the technical merits fall far short of the proposed remediations. It is therefore likely to have been funded or otherwise inspired by the NSA in an attempt to smear PGP, still the most effective cryptography available to the average person.
> we have a political system in which the federal government, having devolved virtually all decision-making power to states

That's definitely not true. Just look at the ACA.

> California's high-speed rail progress—its proposed San Francisco-to-Los Angeles line remains the only truly fast train project in the country—is the exception that proves the rule; that state's size makes it no example for the rest of the nation.

Yeah let's just pretend that California's train to nowhere is an example other states should emulate.

We can't build high speed trains because: (1) the government is corrupt, incompetent and beholden to interest groups and (2) the public doesn't really want them.

The best example of public transportation the US has is probably NYC and it really isn't all that great. It's dirty, slow, unreliable, crowded and surprisingly expensive. (at 100$/mo owning a car in almost any other city in the US is cheaper)
Thanks for the tip on GarlicJS! I just implemented it and it was super slick.
> Classical mechanics is also indeterministic, you just have to know where to look.

On the contrary, classical (pre-quantum) mechanics is certainly deterministic. The first real challenge to a strict relationship between causes and effects was QM, which (as you may recall) caused Einstein to begin a long campaign against those ideas -- "God doesn't throw dice," and so forth.

> But we can predict NEITHER when NOR which direction.

Our inability to predict an outcome doesn't constitute an argument against determinism, only the limits of experimental measurements.

> analogous if not in fact homologous to how the radioactive decay of a single particle cannot be predicted.

That's simply false. A radioactive decay's timing is certainly nondeterministic, but the direction an observed, macroscopic ball takes is deterministic, even if we don't get the memo.

Think a bit harder. If Norton could demonstrate the indeterminism of classic mechanics, as opposed to publishing a philosophical paper on the topic, he would win a Nobel prize for undermining a well-established physical principle. But philosophy isn't science.

> We can all behave in ways that are not predetermined.

We can all behave in ways that we believe to be nondeterministic, but free will remains an open philosophical question.
FWIW - I'm pretty sure this is shell-independent. Happens with BASH as well.
There's a bathroom every half-hour on a highway commute.
They're using a deuterium reaction? That's not bad (per se), but the neutron production can create difficulties: major regulatory hurdles (can be used for nuclear material refinement?), difficult to extract energy, and causes a lot of nearby material fatigue.

Another big contender (IMHO) is Tri Alpha's aneutronic approach: http://en.wikipedia.org/wiki/Tri_Alpha_Energy,_Inc.

Either way, cool stuff!
From HackerNews to FastCompany or how I hacked the media for traffic
I imagine a blind person can study light just as well as anyone else, and can learn about the eye and can understand that sighted people are able to detect both wavelength and intensity differences. Just like a deaf person could learn about pressure waves in the air and how they can be detected by functional ears.

But it's probably difficult or impossible to understand what the perception is like, and how rich it is, except by analogy when thinking about how they'd try to describe the senses the do have to someone that doesn't have them.

Our understanding of echolocation in bats or the magnetic field in birds is probably similar. We understand what they detect and how they detect it. But I don't think we have any understanding of what it's like to experience that perception.
The most important question: what are the demographics of the founding team?

Best of luck to you and your team, I really think that alternative paths to Fusion should have been explored since Farnsworth. Instead we have the crazy massive superconducting cathedral's that are literally trying to blow themselves apart when you turn them on. Your team and the teams investigating other approaches (General Fusion, Tri-alpha, the late Bussard's Polywell, Lerner's Focus Fusion) all should get several tens of millions to investigate and do hard science and try for the big payoff. Congrats on getting some more initial funding, I wish you the best of luck.
>False choice. Cities have sophisticated, multi-level rail and surface mass transit systems for a reason -- they make economic sense.

The constant financial troubles of all of the rail systems in the Bay Area seem to tell a different story. It's almost as if everything is not as black and white as you believe...
There are really only 3 or 4 viable high speed rail corridors in the US:

Northeast Corridor (Boston - Washington DC)

LA - SF

Chicago - NYC

and possibly Seattle - Portland

Beyond that, the traffic densities present are not enough to justify high speed rail - not to mention, even nonstop at 200 mph from LA/SF/Seattle to Chicago (or any eastern point) is a minimum of 10 hours in transit, versus 3ish to fly.
Backblaze also uses off-the-shelf HDDs (including, when HDDs were in short supply after the flood in Thailand, buying USB drives and tearing the case off). They publish a lot of reliability numbers on drives as well (which match up quite well with my own experiences), as well as cost/GB numbers.

What is their real motive?
Let's say you joined a tech incubator. Let's say you decided that it was in the best interest of your company to depart towards the end.

Let's say when reaching out to deliver your incubators' stock certificates they declined to accept them and preferred to offer you a promissory note on really generous terms...

Would you smell a rat? Why would they not want the stock certificates?

One may say; "they don't want them because they will be worthless as you're likely to fail - especially without their support."

Ok, but if the stock certs are worthless, why invest in high power lawyers to draw up a promissory note where the "startup doomed for failure" will have no chance of paying the money back anyway?

All I can come up with is this; a) bound by the terms of the initial offer letter, their providing you with the outstanding balance of services they failed to deliver is more expensive than just drawing a note b) maintaining oversight of their investment in a startup doomed for failure is more expensive than issuing a note...

Really want to make sure I'm thinking about this from all angles.

Please - I welcome you guys' thoughts.
beamed down in realtime to a group of (real) engineers on the ground

I assume this is in reference to use of the term "race engineer" in F1.

I can assure you that the sport does use real engineers, and very intensely so. Folks like Adrian Newey would qualify as engineers by anyone's definition, and each team has heaps of MechE's, EEs, software engineers, even materials engineers, back at home base.
this is a point I can agree with/ponder especially as a techie

the problem is hard though...you could pay for long bureaucratic studies on whether this would pan out or not

or you just do it

problem is that building the cell phone was several orders of magnitude cheaper than plopping down $100B for high speed rail infrastructure. Definitely not the business model of "launch fast and iterate". Which is probably why its hard for this forum to debate it.

> I have to ask -- who are you working for? Your arguments are all paper-thin, easily torn to pieces. Roads and cars are democratic? More democratic than a seat in mass transit?

This is not at all constructive. And I believe the author probably meant "individualistic" rather than "democratic."

There are no sound reasons for investing in passenger rail in the US now. The current system is already meeting demand, and on a national level all lines except the North East Corridor requires heavy subsidy.

If there were a pent up demand for it, it would have happened. We could artificially create demand by jacking up the price of petrol, but then we are taking choice away from the consumer.

Building better, faster trains is hardly a guarantee that they will be used. My experience (which I admit is purely subjective) is that people who want nicer trains already use them. I live in a major transit corridor to NYC, and the folks who already ride the train would love it to be faster and nicer, but would they pay the higher prices? Why are they all taking slow NJ Transit instead of high speed Amtrak?
What about amazon affiliate links for very specific products targeted at items those people hitting that page would be interested in?
It could be that the US's high-risk/high-reward/failure-positive ethic means that elastic transportation routings are more economically valuable than fixed-segment trains.

A train is 10% better than a jet from SF to LA. A train is much worse than a jet for SF to NY. All other pairings -- or so one might argue -- are so much lesser in density that the elasticity of roads is vastly preferable.
I don't understand this line of reasoning. When you go on a date, do you pick up the check for your SO? When you go to a bar do you buy a drink for your friends occasionally? Surely you'd rather save that money, but you have to "hack" society's rules so that they will like you.

Maybe you "hack" HR policies that reinforce the use of proper grammar by refining your resume. Or hold the door open for somebody who is behind you when you'd rather just be on your way. Society is full of norms and social cues, and I don't think it's deception to control your behavior to align yourself with them. To not do so out of some notion that we should combat human instinct is rather naive.

I think Benjamin Franklin put it best: "Eat to please thyself, but dress to please others."
