It works really well about half of the time for me. A really nice effort, but I do notice the other snake "moonwalking" sometimes and reversing several steps before retracing their route. Sometimes I am able to kill them while being several pixels away. It's an awesome start and a great excuse to learn Node though.

Hard to take this article too seriously when it makes an egregious error regarding the quality of US automatic rifles in the very first paragraph. The M1 Garand was one of the finest rifles built, and George Patton considered it the "greatest battle implement ever devised."
Sounds a lot like some of the ideas in this NASA-produced survey of possible drives- http://www.grc.nasa.gov/WWW/bpp/1997-J_AIAA_SpaceDr.pdf

What exactly are you talking about here? The federal government is supplied by CDU (conservatives) and FDP (neo-liberals), and they do have the majority in parliament (see http://www.bundestag.de/bundestag/plenum/bilder/sitzverteilu...). However, the FDP lost a lot of votes in recent state elections (but has somewhat recovered during the last one).

Are you talking about the Bundesrat (upper house), where SPD (social democrats), Grüne (greens) and Linke (leftists) are present (you can look at the current allocation of votes at http://www.bundesrat.de/cln_235/nn_8328/DE/struktur/stimmenv...)?
You're ignoring the elephant in the room that I mentioned in my last paragraph: We have no idea what the worst-case looks like. We only know it will be beyond imagination.

Please do your math again, and now factor in 3 simultaneous meltdowns in USA reactors, due to plane hits.

Yes, this is exceedingly unlikely. I'd say about as unlikely as passenger planes deliberately crashing into the WTC.

I did think about putting in some "useful" code, like encrypting data, but then people would be complaining about the implementation of the crypto libraries. The point was to demonstrate how easy it is to block the Node event loop, and the impact on concurrency.
What's the net capacity of pumped storage though?

Other problems: you require a pretty significant hydrological infrastructure for PS: upper and catchment resevoirs, and a sufficient gradient to provide a net energy differential.

The logistics make multi-purpose use of PS systems (vs. typical flood-control or irrigation reservoirs) somewhat problematic as water levels may fluctuate dramatically over a brief period of time, and spillways/headways constitute a significant flash-flood drowning risk unless access-controlled.

Still, yes, pretty efficient energy storage systems overall.
A thoughtful critique of PHP. Good. Here's the thing, for those of us who use PHP on a daily basis, we are all well aware of all of this.

I have almost 100K lines of PHP code and only one of them spits out HTML. That would be the line that fetches the initial HTML template which is static and spits it out. After that, everything is XHR and web sockets. The DOM is manipulated directly by client-side JavaScript.

Why use PHP? Libraries to use any database I can imagine. Existing libraries for any API I can imagine. Language maturity. Familiarity and similarity to C.

I know the mines and I stay away. On top of that, those maintaining the language are aware of them too and they are slowly deprecating them.

> PHP is a supposedly dynamic language, but it almost goes out of its way to make manipulating complex data structures difficult.

Why would you use complex data structures in PHP? If you did, why try to manipulate them?

PHP is a language that is made for the web. On the web, anything that is computation heavy, like data manipulation, should be done on the client's side. Not that JavaScript is much better at data structures and manipulation, but at least it probably has a monster of a CPU and a boatload of RAM to smooth things over.

Patents in the software industry cannot actually do good - why? Because patents are wrong to start with and the conditions of the software industry (fast-moving, high volume of research/invention) magnify the problem? Because the patent office isn't sufficiently equipped to grant reasonable patents on software (judging 'obviousness' etc.)? Because all these HNers have personal experience of being constrained by patent issues? Because coming up with ideas for new software methodologies/techniques is not comparable with the R&D of other industries?

It's not the concept of patents, it's not that large companies are using them, it's not that people are enforcing them, it's not any of that nonsense...I think you had a grasp on this concept earlier, but lost sight of it when you tried to analyse it too closely.

This sounds a bit supercilious.

I don't think conservation of momentum is under fire here - the vacuum fluctuations (due to second quantization, quantization of electron, quark, etc. fields) might pick up the difference... although I don't really know enough QFT to be definite.

Kelora Patent Found Obvious: Are Other “Obvious” Software Patents In Danger?
Patent trolling as a business, which IV has proven is viable, relies on a precondition: patent litigation must remain expensive. In specific, it must be prohibitively expensive to determine whether each and every asserted claim in each and every patent asserted against an "infringer" is valid. This determination can only be done via patent litigation.

What happens if this precondition does not exist?

The patent trolling business will fail.

This is because everyone knows most, maybe even all, of the claims in the patent portfolios the patent troll has amassed are not valid. They are potentially worthless. Companies simply do not know which ones are valid and which ones are not. And it's too expensive to find out. So companies are willing to negotiate instead of engaging in patent litigation.

If we were to make patent litigation so inexpensive that anyone could afford to "call the patent troll's bluff", these ridiculous patents would never be filed for much less asserted. In other words, if we could have an inexpensive determination of what claims are valid and which ones are not valid, we could separate the wheat from the chaff. And these enormous patent portfolios would shrink down to size. Just the wheat. If there is any. It would be difficult to make hollow threats and engage in IV-style extortion.

It is only the expense of finding out whether a claim is valid (through litigation) that makes patent trolling a viable business.

Maybe patent lawyers managed to get the best of Myrvold while he was a CTO, and he believes by opening the gates for a vibrant patent trolling industry, he will make life easier for every technology company in the future. All they have to do is pay some protection money and their worries will be gone.
I appreciate the information the author shared in the blog post instead of just linking us to a game without any context.

For instance, he points out that the source demonstrates how to use Box2Djs for physics, handling touch/multi-touch/accelerometer, and auto-resizing the canvas.

It went from something I'd play around with for a couple minutes to a bookmark & a repo I'm now following. Thanks for the extra effort.
There is an argument that the IPO buyers from the roadshow deserve a premium for buying in bulk at a predetermined price before they have the full information of the open market.
It is demonstrably true that no insurance company is willing to take on the full risk of insuring a nuclear power plant against disaster.

The reason for this is that insurance companies aren't gamblers - they don't like insuring against minutely-likely but stratospherically-high-cost events, even if they can charge a premium that gives them a positive expected value. That's because they have to factor in that with such a high payout, there is a risk of destroying their business altogether. You can't capitalise on the positive expected value over 1000 years if you went bankrupt in year 3, even if that was just due to "bad luck".

This is just like the understanding that poker players have, that you need a considerably larger bankroll than the stakes you are playing in order to ride out "variance", as it's known.

Insurance companies understand risk.

Yes, you're right, it would cost a lot to create the katana image by hiring a hot blonde martial-arts expert, buying or renting a katana, and rigging expensive lights in a fancy hotel ballroom.

Inconvenience of using non-Apple products is part of Apple's design philosophy. They have no interest in interoperability beyond what came accidentally when they used BSD/NEXTStep tech to replace OS 9.
Actually, most of the damage came from the burning of the fuel. It's worth noting that most nuclear plants have very different construction and design that make them far more resilient in the face of such a disaster... like significant portions being designed to operate continuously at high temperatures...
JS events using in these JS only apps conflict with Pentadactyl and Vimperator for me. :(

I thought this was going to be about how you need varying levels of experience to get a job, sometimes unreasonably. Which got me thinking: that's a social problem that maybe one of these left-field startups could solve. Provide a service which gets young people 'experience' to put on their CV for when the graduate and start looking for work. I guess what it would amount to is internship/apprenticeship arbitrage.

Patents aren't supposed to lock up abstract ideas, they are supposed to unlock concrete implementations of ideas (unlock by giving details of the implementation to the public in exchange for a short-term monopoly).

There are good arguments either way for whether this is a good idea, but make the ideas far more abstract (like software) and add incredibly short technology cycles (like software), and there is no doubt it's a bad idea.

Ontario here. A few websites have been persistently trying to show me French. The fact that my dynamic IP sometimes shows up as being in Montreal doesn't help at all. But some websites just seem to assume that all Canadians speak French! Luckily, most Anglo-Canadians know by instinct where to locate the English version. We've been thoroughly trained to do that :)

I wonder what it's like in Switzerland.
Very fun :)

Japan has 50 reactors. That's an investment of more than 100 billion dollars.

Currently none of those is operating. Several of them will stay shutdown.

That's a huge economic loss.

You need energy to move the mirror that is used to create the photons.

In the report, it isn’t clear if the photons are released or not. If they are release it is not a reaction-less drive, it only throws a photon jet instead of an atomic jet. If the photons remain inside the cavity, the device violates the physics laws, and after building it they will find that they forget to include some little detail that makes the device not useful.

It is important to remember that quantum mechanics is strange and the Casimir effect is very strange, but none of them violates the conservation of momentum law. The problem with the conservation of momentum law is that to prove it, you only have to suppose that the space is invariant under translations (if you "move" the universe 1 foot to the "right", the physical laws don’t change), so any sensible physical theory comply with it.

>>It is no coincidence that interaction design is replacing technical prowess as the primary competency at startups. People who create great experiences will be the most valuable to startups, and startups that create great experiences will be the most valuable to users.

That's conclusion is a step too far from the majority of the post. Usability is the most important differentiator when all technology is adequate, but when it is not the fact that the technology exists is most important.

Though I mean most social media, and even things like Heroku and Parse is about experiences, but real technology startups like Planetary Resources or Google care most about technical prowess.

Edit: I just find it somewhat annoying that this article leaps from "startups choose to innovate in experiences instead of technology" to "experiences matter more than technology".

When I played, it looked like if you run into each other in the first 1-3 segments of the head end, it will declare it a draw. However if the player runs into you further down the chain you'll win.
It's worth noting that most nuclear plants have very different construction and design that make them far more resilient in the face of such a disaster

We've seen how these designs fare in the face of an earthquake and flood.

We're both arguing on the grounds of mere guessing here, but my guess would be that a plane crash might very well cause similar disruptions.

Also if I was a terrorist plotting such an event, I might just fly two planes into the same reactor - because, why not?

The question is not about how such an event is executed but how likely it is. I hope we can agree that a dedicated team of individuals will find a way to cause a catastrophic event in these facilities.

And that's precisely the problem; Nuclear plants require something that we can't provide: Perfection.

We may be able to keep the nominal failure rate at the level that we've seen (Chernobyl, Fukushima). But all economic calculations that these plants have going for them are immediately invalidated when you start considering a single successful deliberate attack.
Also we're not only talking about the main reactor housing. Much more radioactive material resides in spent fuel pools which might not be as well protected as the reactor, see also

"It was officially adopted as a United States military bolt-action rifle on June 21, 1905, and saw service in World War I. It was officially replaced as the standard infantry rifle by the faster-firing, semi-automatic 8 round M1 Garand, starting in 1937. However, the M1903 Springfield remained in service as a standard issue infantry rifle during World War II, since the U.S. entered the war without sufficient M1 rifles to arm all troops"

Thanks Wikipedia, that was easy!
Ten bucks says you are using proprietary drivers...
Hate is a pretty strong word, but I was never happy doing it and didn't agree with a majority of things happing at the company.
While the M1 Garand may have been one of the greatest battle implements ever devised, it was semi-automatic, not fully automatic. The article probably refers to the M1918 BAR.
Not seeing a redesign here... perhaps they are rolling it out gradually?
They have gotten angel investments, but there haven't been any VC's yet, the industry doesn't have a lot of hype and the company has yet to prove they have a sustainable business model.

A charitable way to read this site is to use it as a way of talking about current trends. For example, they say "Male and female salaries are reaching parity" in 2067. Who knows what'll happen, but it's a novel way of talking about just how far behind female salaries are and at what rate they're changing today. For another, projecting Moore's law out to 2083 is silly, but it is interesting to remember how transistors (and other computer parts) have been shrinking exponentially through the present.
The bad parts of Go are mostly the tradeoffs you have to make for a systems programming language. They have benefits but also some unfortunate downsides. Some are just implementation details that will get solved over time.

* integers overflow

* sharing memory between threads isn't safe

* mutable state/ shared state

* nil pointers

* block scoping can lead to multiple different variables with the same names within a function. Sometimes confusing.

* value types limit certain conversions. eg. you can't convert an []int to an []interface{} directly because an int and an interface{} are different sizes in memory.(http://golang.org/doc/go_faq.html#convert_slice_of_interface)

* Error handling can become quite verbose if you don't design your code to limit the places errors can come from.

* gofmt is awesome, but in some rare situations the default format makes code less clear, so you have to change your style of code to fit the formatting.

* 'go get' is awesome, but it's lack of centralisation makes it harder to find the good 3rd party libraries amongst the bad/incomplete ones.

* The current goroutine scheduler is really simple and moves goroutines between threads and CPUs. This leads to lots of cache misses, so running on many threads can become slower than running on a single thread.
I'm lazy, but I still don't think 16 hour days is very sustainable.
Wouldn't this be against the law as causing interference, especially with emergency equipment (in the US)?

Or do those FCC rules only apply to devices?
You're right, so that is what I did.
Passive blocking is fine, active blocking or interference is not.
Well, in the linked article you can see a graph showing the contribution from renewables. You can see it's even growing a bit. It's just nowhere near ready to replace coal just yet.

We absolutely should be pushing them and they represent our long-term solution but the 5-10 year plan should be shutting down coal. That means you need an alternative ready to go now.
This blog post seems a bit lazy, and lacking in true references (a link is better than nothing but still isn't a great way to cite a source). It raises a good point, but I'd much rather read an article or book that used proper references and made a stronger point. I think the book that kawera linked to might do that.
I listened. Kinetic energy is the mass times the square of the velocity. F4's go way faster than 737's. Thus kinetic energy is comprable between the two.

On the second point:
http://en.wikipedia.org/wiki/Containment_building

"The containment building itself is typically an airtight steel structure enclosing the reactor normally sealed off from the outside atmosphere. The steel is either free-standing or attached to the concrete missile shield. In the United States, the design and thickness of the containment and the missile shield are governed by federal regulations (10 CFR 50.55a), and must be strong enough to withstand the impact of a fully loaded passenger airliner without rupture.[3][not in citation given]"

It's also not my nuclear reactor. My power comes from hydroelectric thank you very much.
Nice job, spent a good 30 minutes playing this :) Brain virus.

I encountered some bugs where there was a guy who couldn't lose. He just kept going straight and when he ran into me he didn't die. Maybe someone cheating by editing the JS?

Also, I noticed some glitches where other players' snakes had a really high velocity. Or was that a power up that I didn't get?

Tangent: Does anyone notice CRAZY GC pauses on Firefox, or something that appears every 5 seconds or so? It makes the game almost unplayable on Firefox. Switched to Chrome to play it.
I think switchable is something different; ironhide/bumblebee are for the newish "optimus" setups, which currently only work properly for windows AFAIK. It's quite neat: rather than switching between cards, the discrete card is used only for the windows/apps that need it, while the integrated card handles the rest of the desktop.

The ironhide/bumblebee solutions work by running another X display, and using virtualgl to draw the window from the discrete card on the main desktop -- but you have to explicitly invoke the applications that you want to run in this fashion.
At one point I was playing two games at once, from what it looked like! Otherwise, very cool and a lot of fun. On Firefox 12.0
