> The energy does not disappear.

Below break-even, the source power is requires to sustain the plasma in a high-energy state to maintain fusion. Therefore it's unavailable. Any effort to extract more power than the fusion reaction produces will extinguish the reaction.

Example -- let's say we have a fusion reactor that doesn't achieve break-even (example: all existing laboratory reactors). Let's say very hypothetically that heating the plasma sufficiently requires 1000 watts (sometime in the future) but the fusion reaction itself only produces 250 watts.

Once the fusion reaction has been established, we can only extract 250 watts from the system. Any effort to extract more will extinguish the reaction. Therefore more power must flow into the system than can be taken out. It's endothermic.

Which word didn't you understand?

> If you put in 1, and the reaction gives you .5, you have 1.5.

You, too, can learn the physics required to understand this system. You just have to think a bit harder.

> You do not have to maintain a stable reaction

On average, yes, you do. This project has a peak and an average power that differ greatly, but terms like break-even still have their normal meaning, which is why NASA mentions break-even in the project's documents as a required project goal.

http://www.nasa.gov/directorates/spacetech/niac/2012_phaseII...

Quote: "A subscale, laboratory liner compression test facility will be assembled with sufficient liner kinetic energy (~ 0.5 MJ) to reach fusion breakeven conditions."

What does break-even mean in a pulsed fusion generator? It means the average output power is greater than the average input power.

> They are not making an electric generator, they are making a rocket. They are not the same thing.

Yes, they are the same thing. They both require break-even, and they both rely on a fusion reaction.

> You are trolling!

I know this subject, you do not. Therefore it is you who are trolling when you should be reading.
Yeah I'm sure some people do exaggerate.

I'm not looking to rain on your parade or anything. I see the value of this product, but I have a question.

Why did you use an inbox for the user's data? I reason it is not the right definition. People hate the inbox. It actually turns them off from using products/services. I've tested it and mentioning the word inbox makes conversions plummet.

I would call it collections, queue, stack, or something else. Even panel.

I do like the process to join in, but I would test the flow through which people create accounts. I'd have them start saving stuff first, then requiring a password to save the data.

Anyhow, good luck
HTTP: The protocol every Web Developer must know – part 1
Google wants every site to buy ads, so they engage in everything possible from adding dozens of ads on pages, to demoting entire niches, to FUD to force you to advertise. When Google has ads for a certain keyword, they don't care much about "organic" results, they care that ads are better. In fact, several threads at Webmaster World have shown a lot of obvious examples where Google makes results worst to have a better adclick ratio. Everything Google does is to make money via ads, from Chrome to Android to Search updates, especially during Larry Page's rein. That is the bottom line, the rest is fluff.

Google Shopping is already 100% ads, the rest of the commercial results is 99% ads and advertiser sites (usually huge brands that spend billions on Adwords). Disclosure and ethics however aren't Google's strongest points, lobbying governments is.
Analysts are people that pretend to know more about running companies than those that do but at the same time for some reason seem to be stuck behind desks writing articles, instead of running a successful company of their own.

The Api Paradox
Mt. Gox I believe has a flat percentage fee on all trades so someone can make as many micro trades as they want and still pay the same fee as one large trade.

It's pretty easy to solve by charging users who make over a certain limit of micro trades. I wonder why they haven't done this?

A million times this. So high off the ground, and soooo inefficient with the tiny wheels. Mad props.
it's simple: the people that bought their ASICs in the first batches that delivered made some more bitcoins by virtue of the difficulty not having caught up to the new reality just yet. So they could mine a larger number of coins in a shorter period. Once the difficulty adjusts they still have an edge over those using fpga's, gpu's and possibly even some cpu's. But after the bulk of the mining has shifted over to asics we're back exactly where we started.

So this is just a short lived spike and then the situation will revert to electricity cost plus.
But it still sucks for Microsoft. Because those sales include the "hybrid" sales, too, so whatever this means for the "PC market", it's still very bad for the "Windows" ecosystem and Microsoft.
So Google expects everyone will hit http/search while logged in so they can get the users preference and redirect him?

I wouldn't consider a private recording a "Big Brother" thing. It's when recording is mandated and that you have no choice in sharing it, that it becomes "Big Brother"-ish.

Personally, I could see a passive recording feature (say, the last five minutes) as useful in this way. But then we're talking battery life, and I haven't read enough to know about such things for Google Glass.

This is not an issue in the UK. In our schools teachers are provided with data based on prior achievement and demographics of all their students. If a cohort of students fail to reach their expected target then the teacher is usually considered responsible. Of course, rigorous adoption of a target based system also leads to teachers, schools and exam boards gaming the system and subsequent grade inflation, but that is a different problem entirely.
The problem seems to be that you can't do tail calls with the C calling convention.

For example, let's say a 0-argument function tail calls a 1-argument one: the 1-argument function expects an argument on the stack, so the 0-argument function must push one.

However, when the 1-argument function returns, the argument will still be on the stack, because with the C calling convention the caller removes arguments from the stack.

But the caller called a 0-argument function, so he won't remove any argument, and thus the stack is now misaligned due to the argument left over there, which will crash the program soon.

However, just switching to the Pascal/stdcall convention, where the callee removes arguments from the stack should just work; it might be slightly slower, but on all modern architectures (i.e. those that aren't x86-32) parameters are going to be passed in registers anyway for must functions, so it shouldn't matter.

The problem of that is that non-varags functions cannot be called with a varargs prototype; this is an issue with K&R C that allows calling undeclared functions, but isn't an issue with Rust.

So, I'm not quite sure why Rust doesn't just switch calling conventions and support tail calls.
Instruments do not have scales.

Actually, most trumpets, harmonicas, and many classes of flute are restricted to diatonic scales. You'll have a hard time finding a chromatic trumpet outside of a museum.

There's more to music than western chromaticism or indeed harmonic theory.
It’s also my Github birthday, as I joined on April 11th, 2011!
Thanks for the feedback, guys. I will look further into this.
Although you wrote you'll never do it again, IF you were to do it again anyway some day I would like to advice you to have another look into a longboard, and choose a day when it's nice weather! You'll have a lot of more fun riding.

Check out http://pavedwave.org/ (The Soul of Distance Skateboarding). On the forums you'll find tons of advice (skateboard equipment, technique, nutrition) which can help you achieve awesome goals. You can also find events over there. If there's one time an event close to you you should really check it out, it's a great experience to come together and ride for 24 hours! (sound funny huh)
Couldn't agree more! MVPs are about plumbing, not about architecting. Grab whatever you can get your hands on and plumb it together to serve your test needs. MVP coding reverses many of the 'be a good coder' doctrine - for example:

• DRY vs. Cut & Paste (it's faster than abstracting and creating a common interface etc...)

• Avoid Glue Code vs. Duck-tape Code to hold open source components, hacked sample code and other code fragments together

Fast MVPs ftw!
"crime witness aid for police" would probably be beneficial by itself, if it is possible to limit the privacy and surveillance concerns. So essentially the situation, where a witness starts to film a crime and then gives this video to the police. Or the police could be required to document everything they do (by taking a full video of each shift).

On the other hand, the surveillance potential is of course scary. And once Google glass is out, I really do not know how to limit the impact.

It sounds like there might not be a 'next-time' in the near future, but maybe think about putting some lights on if you're doing another 3am start. Even riding my bike at 6am without eye-searingly bright front and backlights makes me very nervous, I'd be terrified skating on the road in the dark.
> A tweet from Ambrosia's official Twitter states that the company is still in business

I worked at a small consulting shop that had one large client providing most of the work. There were rumours of problems with this client not having the funding to continue the upcoming projects. One day a couple people were let go which lead to rumours that serious layoffs were coming.

The next day the director sent out an email stating how everything was fine and while, two people were let go yesterday, we shouldn't expect any more layoffs.

The next week I was let go with about half of the remaining company and another layoff followed which reduced the company down to a shell.

I really don't think it was malice or lying. Most people are just optimists and want to believe that everything will turn out.

That being said, if I worked at a place again where I heard rumours going around I wouldn't wait to start looking for something new.
Andrew Welch used to hang out on MacNN forums and he really wanted the war in Iraq. So good software and horrific politics.

Well done. Great attitude.

Reminds me of beginning a long hike and feeling the pain in your calves start too early in the first hour. And knowing that you have over a week to go. But you just do it rather than skulking back.

Had a full day hiking from Italy to Switzerland in torrential rain, too stubborn to stop at the start, then unable to find a flat spot to pitch a tent later. Obviously traffic and road conditions on a skateboard are one thing, but I think you'd be hard pressed to die from rain itself otherwise. Still, it's such a mental deterrent at times.

Did you take the detour along the Sea Cliff Bridge?
Bah, PC makers have done this to themselves. Look at their starting lineup...compare it to your average tablet. The tablet is, surprisingly, a better experience. Why? Because it has a solid state drive.

It's kind of like what would happen to Porsche / BMW / Mercedes-Benz if a car maker came along that offered an electric sports car for $20K that performed like their $70K offerings. No one wants to buy a $50K BMW that performs worse than a $20K electric car...that's easy to understand. Unfortunately, these PC makers haven't grasped this concept...which says a lot about them; they are too intent on preserving their price structure (that overpriced upgrade to a SSD) to realize that they need to spec them in standard, or they will collapse (their company will shed stock). The nature of the game has changed, but they're still worshiping Jobs and picking over his final words for any hidden meanings to guide them to profitability. Yesh.

I mean seriously, Ultrabooks? "Oh yeah, we'll just copy the MacBook Air, and BAM! Profit!" Because that's what consumers want...a more expensive, less useful version of a laptop. Only now that the Jobs reality distortion field is fading are we seeing people wake up, and wonder whether they really want an iPhone 6.
Innovations in infrastructure are usually unknown to most of the people using that infrastructure--until they fail. Think of what would happen if Github was down for a week: how many users would now have the name "Github" on their lips (probably with a negative connotation) after some web service they do use said "sorry, the fix on that showstopper bug has been delayed a bit; Github is down, you see."
https won't prevent the whole redirect request to be logged and stored in an decrypted format. Google will take a comeplete search string (search/#search=things+I+want+to+buy), and redirect that . the search parameters are perfectly visible for the redirect server.
Just because the company is still in business, doesn't meant that the title is incorrect. Fairly standard milking.

I wouldn't call what Thatcher brought in 'free market' per se, although I dont think this is what you are saying. Many of the formerly nationalised companies that are now supposedly private depend heavily on state subsidies. Her implementation of change swapped one inefficiency for another while setting vast swaths of the country at loggerheads. Other countries have managed to implement painful change without the friction experienced in the UK. It's a sad period of history.
You make a good point, unless someone creates an ASICs machine that can compute 10-20x the current hardware.

Such a shame if true. I lost count of the number of hours I spent playing and modding Escape Velocity. For a long time from the mid 90's through mid 00's there was an incredibly active community around that family of games. I still have my two Ambrosia shirts A.

An SSD is a fantastic upgrade. If you already have one you're all good.
> It probably just makes wasps really angry.

It makes them drunk-ish. Alcohols — especially very sweet or spoiled (for weak alcohols) ones — are good for wasp traps though (the reverse-plastic-bottle things), works infinitely better than the usual syrupy water as the alcohol and fumes will knock out yellowjackets and their ilk (and hornets) and reduce the (low in the first place) chance that they'll find a way out.
My guess is that inbox allows people to add more to kippt because it decreases the mental effort required to file the item into the correct tag/folder. Its a dumping ground were you add things and promise to sort later.
Probably the biggest contribution a non-coder could do is bug-triaging, which means: Look into newly reported issues and try to reproduce them and check for duplicate issues.

In the best case, you can simply reproduce it. Then say so in a comment to the issue. However more probable, you have to ask the reporter for more details or try different versions and environments.
Add spam filtering ASAP. In the past I had created a URL shortner, even created an API and the usage exploded but most of the links were created by spammers and I used to get regular warnings from my host. In the end I just shut the whole thing down. if you just want to shorten the links with your own short domain, better use bit.ly. They even have basic analytics and it's free.
There is a more or less automatic return to a state of equilibrium because even if you came up with a way of advancing the state of the art by a factor of 10 or 20 then sooner or later you'll be caught up by the rest. So the window you've got to gain dominance is extremely short, both because the bitcoin network will re-adjust for even your (percentage wise) small contribution and the tech catch-up is not long behind. That's why most parties that advance the tech chose to sell their findings rather than to capitalize on them by mining. That way they get to recoup their investment faster than if they'd be dependent on the window of opportunity afforded by advancing the technology and mining.
A small nitpick: Volume is one metric but it does not matter in reality the important part is the amount of transactions on a specific symbol.

That's quite right, thanks :)

Real venues incentivize participants to post orders in round lots (generally 100 shares) and some of them penalize participants who add liquidity with extraordinarily low fill rates. These rules help reduce load on the matching engine, and afaik mtgox has no analogous rules.

> Yet it's still too early to write the PC’s epitaph. It will take another year or so to see whether Windows 8 is accepted by business users, who drive most PC sales.

I don't think so. Not unless business decides it wants random coloured squares combined with mad inefficiency...
Although I acknowledge that lead is nasty stuff, something about this issue bothers me.

According to some studies, increasing exposure to lead at low levels (1-10 micrograms/dl) shaves 4-7 points off IQ scores[1].

Yet, as population blood lead levels have plunged in recent years, there haven't been proportionately massive gains in IQ in the population. Indeed, the Flynn effect may have stalled in recent years[2].

This either means that there are confounders or some other effect is in place. But I'm no expert, and I'd value the input of someone better informed.

I just got a new desktop this month - faster CPU, more ram, SSD, etc - it really is a lot faster than my 3 year old one. So I don't think hardware improvements are an issue, computer speed is still increasing heavily, and dropping compile time and allowing more programs open at once is always great.

However, since I built the PC myself, I could choose what OS to install, and I'm using Linux and Win7. If I was a more regular user, I'd be forced to use Win8 - and if that was the case, I would not have upgraded. If this is true for other users, then it's clear to me that Windows 8 really is to blame here. I would certainly not purchase a computer running Windows 8 for desktop work, and I believe a majority of desktop users agree with me.
Fair (though a bit pedantic :P).

And to be clear, I don't really _hate_ them (or the system). I had to phrase it that way as a rejoinder to his statement; but I am deriving _so_ much amusement out of this whole debacle.
That's dire. What did you use the pipes for? And was there the option for some private crowd to buy up any of the works? How did your company deal with this - I know materials aren't all the cost of a big job, but a 500% percent rise in material cost is pretty hard for anyone to absorb.

Dang, they were later known for their utilities, but I was raised on some of their games on OS9 and X! Apeiron, Bubble Trouble, Uplink, Escape Velocity (and sequels), Barrack, Swoop and of course Maelstrom. A few were definitely remakes of classic games, but they made them very well. The RPG simulations of Uplink (hacker sim) and EV Nova (space sim) were excellent.

Bitcoin needs a high performance, extremely secure, open source trading engine, with a standardized API that traders can use to arbitrage the exchanges.

The tricky part is transferring other currencies in and out, and between the exchanges. "Ripple" also sounds promising for this purpose.
At the consumer level the cheap laptops and desktop PCs in shops make a big point about the capacity of their hard drives. 500Gb bottom end, 1Tb more common. I'm assuming it is the 'bigger number looks better' pitch. They even have little labels saying how many songs/pictures/videos you can fit on the disc.

Anyone done research on how much storage is actually used? I've never filled a hard drive yet but I'm old school with music.
> "Dr Tongesayi also said that the increasing practice of sending electronic waste to developing countries - and the pollution it leads to - exacerbates the problem."

The words "electronic waste" don't really convey the scale of the problem.

I used to imagine piles of computers, with people able to strip out the copper, tin, lead, gold, aluminum, steel, etc for sale. I knew conditions would be a bit rougher than UK factories, but I imagined some kind of shack, and some kind of tools.

Here's a snippet from a UK TV programme about the e-waste dump in Agbogbloshie, Accra, Ghana. It's pretty depressing. There's no kind of sensible plan to recovering useful stuff. Seeing a boy smashing polyester / polystyrene caps off an old PCB with a rock is just grim.
