Constant 1g acceleration makes nearby galaxies accessible, nevermind nearby solar systems.

"Break physics" is relative -- things which can be allowed by the laws of physics can be so humanly implausible as to be useless to discuss.

I mean, let me just be totally clear about this. In relativity, to get your time dilation factor γ up, you need a lot of kinetic energy K. How much? Well E = γ m c² = m c² + K, so K = (γ − 1) m c².

If you wanted to go to the nearest galaxy -- which is 25,000 light years away on the other side of the Milky Way -- and you wanted to do it with any sort of vehicle in 25 years -- you would have to take along about 1000 times the mass of your vehicle as fuel. More importantly, whatever fuel you're using to accelerate you're also using to decelerate, so you actually need 1,000,000x fuel to start with, to get your 1,000x fuel up to speed for most of the journey. So your 10^5 kg shuttle orbiter would need to come with 10^8 kg slowdown fuel. That's what we're sending around, you've got to build the Great Pyramid at Giza out of antimatter and find a way to carry it with you, just to get the shuttle to do this in a reasonable time.

Now c² is about 10^17 J/kg so we need about 10^25 J to slow down, and to send this would require 10^28 J. For perspective, our largest nuclear blasts (Tsar Bomba's 50 megaton yield) are 2 * 10^17 J, so you'd need fifty million of those to launch. Or you could just carry the US with you, that has an annual power consumption of 10^22 J -- wait, make that a million copies of the United States, before you could launch.

Of course, antimatter is unstable and you might want to carry the Tsar Bomba around as a massive fuel source instead, but the Tsar Bomba actually only carried an energy yield of around 10^-4 m c², so you would need to have 10,000 times more mass (10 million space shuttles to decelerate your one) if you wanted to do it with nuclear bombs.

At any rate, the computer never "has a hard time" -- It's us poor humans that have been having a hard time writing programs that play go.

Can I ask you a question? Is the random move approach simply brute force; or does it turn out that, weirdly, moves which have good outcomes from the approach also turn out to have good outcomes in general, even though the actual sequence of moves weren't actually considered?

i.e. I guess I'm just asking if it really is a heuristic.
CUDA does not know anything about materials, it's only an API to run code on the GPU and transfer data back and forth from main memory to gpu memory. So it's all up to VRAY devs to implement material rendering with the tools they have available.

I think it has to do with what all you calculate into the final sum, although I guess theverge.com - sum is incorrect.

Programming is not a culture. There is a culture around programming similar to that of dulce et decorum est, which may explain why so many programmers see themselves as some kind of jedi knight fighting evil in a clearly delineated black and white world.

The world is not black or white, being a 501 programmer is not a binary answer, it is an answer with many subtle shades of gray.

Instagram didn't change the world, but it certainly did make 12 people very rich. Most people who work on a startup will not become stupidly rich, changing the world is something the people who own the stock tell people dumb enough to believe it. Programming as a culture is yet one more of those things. If it was a culture you would not get paid to do it, just like no one gets paid to be Italian.

501 programmers are akin to mercenaries, we believe in the almighty dollar and don't think that the King or country is something worth dying for, and especially not stock options. We go home at 5:01 because we aren't being paid to stay any longer, and we know that the vast majority of the benefits of staying past 5:01 will accrue to those who hold stock rather than to those who stay past 5:01. (If staying past 5:01 is even productive, which many studies think is not)
I do. I'm not alone either.

Google made a deal with the Chinese government to censor search results - also a fact.

Google's penetration in China was very low (we've had native Chinese speakers living with us for the last three years and they had hardly heard of Google).

Not only is Google's share in China low, it's falling.

I like the following advice "Work at the job you do not actively hate", this might be paraphrasing Buffett. Very few are lucky that their most enjoyable pastime that they are good at is also the highest paid.

As it has been noted, for most of humanity some sort of purely consuming task seems most enjoyable these days.

I would much rather play strategy video games or chess, but there is a very limited market for good players. Also, it has been noted playing anything for money actually changes your enjoyment of that task. Corollary - if you are the best at something in the world - you can create your own profession.

Programming is something that I enjoy, but it is not something i want to do 24/7. However, it is well rewarded.

IQ tests are normed for a standard deviation of 15 points, not 10. (And I'll bet you knew that but got distracted by the '3' in 130. The "D'oh! Effect" -- a side effect of our associative memory architectures.)
I do not think they crippled that theoretical CPU, though:

"The floating point performance for the reference microprocessor
is calculated by multiplying the number of floating point
functions units on each core by the number of cores and by the
clock frequency.

This is an idea that's been bugging me for a while.

Something like a multi-track SoundCloud, where uploading a song requires uploading each channel (drums, bass, lead etc) as a separate bounced track. Hitting play for a particular song plays back all the channels in sync as intended by the original artist, or the song can be 'forked' by other users, who can tweak or replace individual channels.

A high-school kid swapping Jimi's solo in 'All Along The Watchtower' for his own, or an electronic artist forking a classical pianist and adding breakbeats... karaoke for musicians.

You'd be able to track songs 'forked' from your own ala github, and forks-of-forks would quickly diverge into something quite unique.

No idea how you'd monetize it (pay-to-fork?), attract users (would the the separate-channel thing be a pretty large barrier to entry for the average musician?), more than likely a legal minefield, and probably not particularly useful to Pud, but I'd love to see it happen :)
Pet peeve alert (as always in the interest of Educating The Public): that's "ms". No capital 'S', since that is a different SI unit, namely that of electrical conductance, the siemens (http://en.wikipedia.org/wiki/Electrical_conductance). Not sure which is more annoying, "mS" or "mSec". What's so wrong with "ms"?

And yeah, I realize the quoted text is at fault, not trying to assault the messenger in any way. :)
Again, in the first case the man is simply spending the 25k on the maid. In the second case he will spend the 25k in something else.

Again, you are looking at the GDP of the man, not of the pair of people.

Because the man first spends 25k, and then the maid spends 25k again, the 25k is counted twice in GDP statistics. In the second case, it is counted once.

This is why GDP != Income.
Because whether various people think they are being paid as much as they should, and how much is actually being produced, are different things.

If you are asking for special provisions from the public, prove the public gets a good deal. How much should the public give? Simply as much as you say? No, that does not work. The public cares about the end result: how much is produced (and available). That is the point.

There has been significant -- or to some, rampant -- 'piracy', and huge 'losses', for a decade: that is what we have been told. But where is the devestation to the amount of production? Where is the terrible shortage of new music being made? That does not seem to be happening.

> everyone will soon be, in general, short of music

So, you admit it has not happened, and is not currently happening.

You will forgive people for being cautious about claims from the general direction of the music industry, and instead expecting good evidence. Everyone likes music, but we should not be giving away money simply because someone else says they should get it.

> As far as I can tell from my (limited) background on chess/go/etc algorithms, they seem to include lots of hard-coded scenarios (like a bunch of chess openings) and brute force searching.

When playing chess at an advanced level, you need to know a fair number of different openings (that even have names). Chess AI programs have a huge library of openings, endings and other game situations that are evaluated.

In contrast, Go does not have a "library" of openings the same way chess does. There are simply too many ways a game can progress. However, in Go, there are many "micro patterns" that repeat over and over again, and you have to learn some of these even at a beginner level. There are numerous recurring formations, like the "Ladder", where one player inevitably loses and it should be recognized after 3-5 stones are in a specific form.

So Go has these patterns that recur, but they aren't as clear and simple as in chess. While a ladder can be recognized after just a few stones, the outcome may depend on a stone on the other side of the board, that may be have been there for 100 turns. This is what makes pattern recognition tricky for Go AI.
One of the main strengths of india is it's ability to create very low cost products of reasonable quality in many fields.it's probably the greatest thing modern india can offer the world.

For example the tata nano has created the whole mini car segment, that has significantly reduced the cost of low end cars around the world. now many people globally can afford to buy new car. Such effect is much harder to achieve than building an ICBM(which is a pretty old technology).

And indians don't take pride in it(if not at a level of buying it, but at least as a national innovation) ? that's a
shame.

There is fluidity to objectives during a game of chess between strong players. For example:

inflicting/preventing weaknesses,
seeking/avoiding favorable exchanges,
occupying/closing important lines.

Then all such long-term considerations suddenly become irrelevant when the game descends into a tactical melee.

At any rate, I don't see how the objective of chess (checkmating the opposing king) is any more absolute or less ambiguous than the objective of go (surrounding more space than your opponent).

Show HN: Punch - A Fun and Easy Way to Build Modern Websites
Personally I've found their price for Personal licenses to be very low -- in the Python world, ActiveState Komodo is $295, Wing IDE is $245, BlackAdder is the only one under $100 and it looks quite "underpowered" when compared to PyCharm.

Regardless, they have promotions running for long periods, so it's easy to start with a trial and then pick up a real license when the price is lower -- the last one ended on 16 April and was 30% off, I got mine last September and it was 50% off.

In general, for software like for everything else, prices reflect what the market will bear. We are willing to pay more, clearly. It's slightly embittering that in this case they cannot bring the usual "import taxes" justification, since they're based in Czech Republic.

I think collbative recording can work well. My iPhone app, Jampipe, is kind of a scratch pad for musicians. Quality isn't the top priority, the main focus is on collaboration. Not sure about drums but most instruments pick up well with the iPhone mic. I sent you an email by the way!

"
We now have in excess of 100,000 confirmed orders for the Raspberry Pi globally and can confirm that everyone who ordered before 18th April (i.e. today!) will definitely receive their Raspberry Pi before the end of June 2012, whatever your existing order confirmation says!"
The point isn't being made about the values of going back home, or living life. Those, again, are generic things anyone, in any profession would be taking up and it would be very healthy.

The point is the subtle-looking bash at open source, and people that hold it as a passion.

Sure, you shouldn't spend your life making a certain someone's dream come true. And if you do, you should be sure you want to make that dream come true.
But you can spend it doing something you love.
Try Tableau, or Omniscope, both are pretty feature rich.

Raspberry Pi: An update for element14/Premier Farnell/Newark customers
You keep using that word, "global". I do not think it means what you think it means.
I used to prefer tabs (less bytes, better abstraction etc), but I've long given up on it. Most tools are not smart enough to switch mode when required, and reformatting entire files every time you want to make a small change on somebody else's code is a real pain (and dangerous).

Community consensus is 4-spaces and that's it.
just ask the dinosaurs

Well, that one might be on the large side. Besides, a controlled re-entry from LEO would have lower speeds than a random solar system impactor and could also use aerobraking.

It still might be too risky, but it doesn't seem totally, obviously infeasible to me.
I'm surprised at the reactions, both positive and negative. I took the manifesto as a humourous criticism of people using our love for programming as a way to exploit us.

As a programmer, I do most of the mocked off-hours activities (except the bathroom thing), but as a professional programmer, I happily leave the office in time.
That's a classic Python gotcha, mentioned in all books and tutorials nowadays.
Also, two of article's four authors work for Xilinx, which makes the FPGA in question.

Does anyone know how much these things cost? A quick google yielded nothing, but I may using the wrong terms.
