Even Apple isn’t sure whether AppGratis actually violated app store guidelines
It is really scary. In Germany they have about 100% of my audience. Bing sends me about as many visitors as a single referrer link on some Q&A site. If Google ever closed our Adwords account we would just die. At least I pay them lots of money so they are probably not really interested in shutting us down.
That could be said the other way around as well. ;)

Now seriously, there's an infinite amount of shades of gray between black and white. I wonder why most people always fall for these dichotomising old tricks.

Anyway, in the land of the blind, the one-eyed man is king.

I was under the impression he was Belgian.
This is misleading. With a one-way function, we are interested in making it hard to find any preimage, not just the one you originally thought of. There are lots of functions whose range is small, but where it's easy to find a preimage (eg: take the first 160 bits of input; XOR all 160-bit chunks together; always return 0).

The avalanche effect (referred to in the last sentence) is important as a heuristic. Among other things, it makes it harder to go from an "approximate" preimage to an exact one. If we had f(x) = y, where y is similar to our target y', we shouldn't be able to find x' with f(x') = y' just by looking at the neighborhood of x. But this doesn't rule out more "clever" ways of tweaking x, and it doesn't obviously stop an attacker from deducing some property of x'. So for one-way functions, what we really want to assert is the nonexistence of an algorithm for finding (properties of) preimages, that is any better than just trying lots of new values of x.

Software decoding of the 1541 disk drive GCR data in realtime
The code solves a real, practical problem that people have been struggling with for 30 years.

The 1541 contains a single 6502 CPU clocked at 1 MHz, 2 kB of RAM and 16 kB of ROM. With such modest specifications, Commodore concluded that the 1541 was not capable of decoding the GCR data in realtime. Commodore compatible 5.25" floppy disks store data as magnetic polarity reversals along 35 concentric tracks on the surface. The key to the solution lies in looking at the problem from a novel angle. We'll use plenty of self-modifying code. This is not really a trick, but an established technique on the 6502 processor. The sax instruction is a mix of sta and stx; it tries to write the contents of both A and X to memory, and due to the NMOS process used to manufacture the 6502, zeroes are stronger than ones, so bus contentions resolve into bitwise-and operations. Thus, we can use sax to store a subset of the bits in A (or X) to memory without clobbering the rest of the register. Furthermore, we can perform a bitwise-and operation using the sbx instruction (a mix of cpx and tax) with an operand of zero, which will leave the result in X.
Doesn't work for me. The language selector seems to change on its own, the right pane never finishes "Loading...", the feedback button opens a blank page.

Also, the start page shows that the right pane is for the camera view of the participants. Why would I want to see the interviewee's face? I want to know how they think, not how they look.

A better use of that space would be a drawing tool, as sometimes it's easier to explain something by making a diagram. Build that and I'll use it.

I call this the "Fart App Generation Phenomenon".

They take technology and use it to satisfy immature juvenile urges and then say, oh, wow, this is so cool. Give them an iphone and they'll write an app showing boobs that jiggle when you shake the iphone.

They waste technology and the power it takes to run it, and they just don't get it. There's a place for that sort of content and those types of apps (bachelor parties, etc), but it's far too prominent today. I hope that changes soon.

Just as with the development of computers and the internet, we can thank the US taxpayer and government for subsidizing pharmaceutical innovations. Which is then sold back to us at hilarious rates.

Pharmas reap wonderful profits in other countries (otherwise they probably wouldn't operate in them), just not extreme profits they can extract from US people. It's propaganda that high US prices benevolently subsidize pharma for the rest of the world; this narrative increases nationalism, and sets up an entitlement complex. Propaganda's a great way to get your targets to believe in their own fleecing.
The US measures infant mortality very differently than other countries, you can't do an "apples to apples" comparison just by naively looking at statistics.

I've read for piano, bass guitar, flute, and now ukulele. I can read treble clef, and bass clef just fine, but stick them together as you do for piano and my brain has a conniption. The exact same figure at the exact same place on each staff represents two different notes. I suspect this is because the gap between the two staffs would have required too many intermediate lines had they re-used treble clef for the bottom staff, but this doesn't mean it is a good readability choice.

Regarding relative position.
On a piano the relative position of notes on the staff almost directly correlates to position on the keyboard. On a stringed instrument this is VERY far from the case. As i proceed up the scale on a simple instrument like the bass i will proceed right on the neck on one string, then drop down a string, shift left, proceed right on that string, drop down a string, shift left, proceed right on that string. So you've got back and forth, and up and down motions to keep going in one direction tonally. On a guitar the strings aren't all tuned evenly so the back and forth on the neck changes depending on which strings you're switching between. On the Ukulele the top string is higher than the string below it so you end up jumping UP strings rather than down, AND the strings aren't tuned at even intervals. So you've just got a big jumble of movements.

Don't even get me started on the totally unintuitive nature of woodwind fingerings or how they are almost totally disconnected from what's going on on the staff.

In short, the relative positioning of notes on the staff is good from a tonal perspective but crap from a finger perspective on most every instrument except piano.

Ah, you guys, sending me off on a research quest about Sam Zemurray, who I'd never heard of before today!

Google Books has an issue of Life magazine with a big profile of him:
http://books.google.com/books?id=2EsEAAAAMBAJ&lpg=PA92&#...

An issue of The Rotarian mentions him:
http://books.google.com/books?id=HUYEAAAAMBAJ&lpg=PA14&#...

It seems he's part of the entire "banana republic" thing.
> a LEGAL obligation to the shareholders to always take decisions that maximise profit over everything else [..] This is not "evil" - this is just how these companies work.

Yes, it is very much evil.

> The only way to combat this is to have a national health care system,that sets their own prices for drugs it buys from companies.

No. All it takes is a different patent system that reduces the (artificial, granted by society) monopoly awarded to patent holders. Or, as a more radical change, eliminate monopolies for drugs entirely and fund research publically.
Education has been on a lets get as top heavy as we can kick for years. Go to any educational institution, anywhere in the US. Check out the oak paneling in the administrative offices. Check out the explosion of administrative positions.
Check out the rise of administrator salaries. That is where the money goes while class sizes increase, teacher salaries nosedive, and essential core subjects get trivialized or cut.
The point is valid, although I believe the author misses the point of design by contract - if you don't explain, how will someone off site, or a few years from now will understand? Moreover, the buzz on the street is TDD which must know what the constraints were, before checking if they weren't broken
"Would be nice to edit the JavaScript as well in the process of debugging it. JS Breakpoints currently (in nightly) block loading of the JavaScript file the breakpoint is in. The file is loaded, just not visible in the debugger."

This is huge for me, it makes debugging impossible when loading.
Pretty neat. I can imagine this syncing with gps navigation and providing street previews for drivers.
> It's always seemed crazy to me that just because electric cars are non-polluting, people forget that dangling on the other end of that charging cable is probably a coal-fired power station.

I don't think that's crazy at all. Think of it as "refactoring" the environmental burden. First you move the energy generation from individual cars to a central energy source. If the energy source (coal in this case) is terrible you won't immediately get a big benefit. However, you have separated the environmental impact of energy generation from combustion motors to a central power plant. So now when you build an infrastructure of clean sources of power: nuclear, geothermal, wind, solar all your cars get the benefit automatically. This is good design. Separation of concerns!

The fact that we're burning coal in this day and age is crazy, of course. Especially given that nuclear power plants are being shut down in favor of coal. Environmental policy isn't exactly rational, but highly politicized issues never are.

I'm pretty sure the Intercat overlords are not going to be pleased. I was thinking about going to TXJS this weekend but think I'll stay home and build my feline shrine to Intercats instead.
I think since 2010 fuel consumption has declined a lot even though weight has increased. So when manufacturers decrease weight, combustion cars will become even more environment friendly.

For example: a big Audi nowadays can do 20-30 km/l. When losing a lot of weight it could even do more. Losing a lot of engine power maybe even more (there is hardly any need to go faster than 160 km/h).

Edit: wow, reading a little into it: in 1899 a electric car was the first to break the 100 km/h barier.

This makes it much it much easier when switching between different instruments of the same family - a clarinetist (when playing any clarinet part) associates one note on the staff with one fingering. If all instruments were in C, the player would need to associate the same dot with multiple different fingerings, depending on the family member being played.
I think the promise is in the future. Right now electric cars might not be as eco-friendly as you'd expect, but once they've become popular, recycling techniques for the batteries will improve, and we can easily switch the generator of the electricity from coal to something like nuclear power to cut back on emissions, the car won't care. When you're driving a gasoline car though, you're basically stuck with gas.
So I guess the most pernicious evil is the sprawling suburbia all around America that for no good reason necessitates car travel all around.

I have a mind-bending question (at least it makes me wonder)

I think it does not matter which energy storage unit we consume right now. Eventually all of them will be consumed. Renewable energy? nope it is not really renewable, it is just another energy storage unit, just renews faster than oil, because it stores less energy. Ultimately the only energy source we have is the sun. What will happen when our daily consumption rate becomes larger than the amount sun can suppl?
All things being equal, stuff is always going to be more expensive in the US than in India. If you're complaining about $70,000 here v. $2,500 there, I'm going to assume you're charging the same for your services here as someone is in India, right? Right?
It seems like the electric car will be important in normalizing the grid as solar and wind projects expand. The hard part will be convincing people that their batteries do not need to be full all of the time, and making cars intelligent enough to ensure that the batteries are full when they need to be.
Old phrase in UK:

"Where there's muck, there's brass."

http://www.phrases.org.uk/meanings/408900.html
Now that I'd like to hear a story of it happening!
Developing electric cars is vital. As is providing charging stations and other infrastructure.

Just because today we generate a lot of power from coal, gas, oil does not mean that in the future we will be 100% clean with renewables (!), nuclear or some other innovation.

The two things should be developed independently, and transportation should be developed on the assumption that the supply of energy will eventually come from a clean and sustainable source.
Two big advantages that this study dismisses are local vs remote pollution, and an easier ability to take advantage of generation mix changes. Even if EVs have the same life life cycle cost, their pollution is always at a remote source further from population centers. That matters for the tailpipe emissions. Secondly, it's much easier to replace a few power plants, or improve their pollution output, than millions of internal combustion engines. If all cars were EVs fed from coal plants, it would be easier to make that clean than millions of traditional vehicles.

On 99% of the keyboards I've seen in my life, the middle row reads like this:

The apostrophe is considered significant enough to be on that row, but so are Ö and Ä. It's reasonable for users to expect that software can accept the letter that is right next to L on their keyboard, yet there remain software engineers who assume that users won't be surprised that things break if they dare to touch this key.

Is the system evil? Yes. Are you evil for following the rules? No.

And as for the patents - how would you deal with a problem that after spending millions on research somebody could copy you and sell the same product for the 1/100 of the price? I know that the US patent system is broken, but this problem is very real.

As for the publicly funded research - this is the best option, but some countries like US oppose this so strongly that I don't think it would work.
