Cardpool (YC W10) Introduces Instant Redemption, Attracts Super Angels
People often fall into the self deceptive habit that thinking about doing something is doing something. Such truisms merit being in a self help article.

Remember she's not an economist. She just writes about it, but from all indications she's not an expert, but a good "pop-econ" writer.
But AFAIK Cherenkov radiation occurs in medium, so there isn't any contradiction to the generally accepted limits, and Ronald Mallet is highly unlikely to be trusted, see the wikipedia entry:

This isn't 73% of random strangers. This is 73% of the Mechanical Turk users who accepted the hit for this.
Actually, the problem with economics is that it is not enough like psychology. Psychologists generally perform experiments before concocting theories (or at least they conduct them to confirm or invalidate them), whereas economists generally concoct theories and attempt to fit those theories to data that has not been acquired through experimentation.

From the actual paper: http://www.fourmilab.ch/etexts/einstein/specrel/www/

We will raise this conjecture (the purport of which will hereafter be called the "Principle of Relativity") to the status of a postulate, and also introduce another postulate, which is only apparently irreconcilable with the former, namely, that light is always propagated in empty space with a definite velocity c which is independent of the state of motion of the emitting body. These two postulates suffice for the attainment of a simple and consistent theory of the electrodynamics of moving bodies based on Maxwell's theory for stationary bodies.

There was an article that was linked to here where a French tech guy (speaking in English though) gave a pretty good video blog analysis of how much the average mobile app developer makes (not much).

Can't remember his name or site though.
Feel free to downmod me, but in defense of the parent, it isn't a summary, but a rebuttal / questioning of some of the points presented.

Some of the questions raised are interesting, and add to the discussion considerably.
Personally I think it's easier to tell people to stop thinking of gravity as a particle or wave - it's not like a beam of light or radio wave.

Think of the space/time as the blanket the universe is wrapped in. If that blanket is stretched out like a trampoline, every object on it or moving around on it is causing flexing and ripples. That's gravity.

When a girl bounces off a trampoline, the specific instance of her gravity is gone but the ripples from that instance continue on for some time until everything "settles".

But apparently the goo that is space/time really does not tolerate anything going faster than the speed of light for some reason. Doesn't mean things aren't trying to go faster than that, they just cannot achieve it.
The gyroscopic effect does not _directly_ make it harder to turn, it causes a reaction force (torque, really) at right angles to the applied force. With two counter-rotating wheels, these reaction forces work against each other.
I agree that the article is, to some extent, an extension of the principle... I do think, though, that most people wouldn't intuitively make the leap to applying the 'invisible hand' concept to software design. Restating a known principle in terms that make it more applicable is still valuable.
Thus, with immediate, online transactions, the opportunity for fraudulent activity (i.e. the use of unauthorized credit cards to purchase gift cards) increases. In response to these security concerns, Tsai says Cardpool has devised a system to carefully monitor transactions and detect patterns.

Are there startups that provide this sort of fraud detection, the way Directed Edge does recommendations?

I've long wanted an extension that rather than translating a full page, translates just the word under the mouse -- ideally without causing any reflow -- so that I could try struggling through reading a foreign-language page, incrementally learning the words as I progress.

Anyone seen such a thing?

It seems it could also mix well with this 'Polyglot' approach, by throwing in some percentage of pre-translated words, or remembering words known/unknown and differentially displaying those.

You are exactly right. This article suffers the common misconception that two wheels spinning in opposite directions and same speed cancel out the gyroscopic stability. And this is simply not true. In fact two wheels spinning in opposite directions and same speeds will actually double the gyroscopic stability (as opposed to one wheel of the same speed).

However, two wheels spinning in opposite directions may cancel out other spinning wheel effects.
In some countries $5/hour is a very good salary...

Even in Russia it's about the average income IIRC if you assume 40-hour workweek.
Exactly. It reeks of buzzwords and consultant speak. Every brush I've had with an agile evangelist felt like a scene from "The Office".

"IIS is believe it or not a very good webserver"

Does it have a portable config file yet? Or do you still have to use scripts to transfer website configurations (which breaks when you have sites configured with SSL for example).

I still have nightmares about reconfiguring IIS by hand for 100+ site IIS servers because the damn transfer script failed hardcore. At least when they switched the config to an XML format I could back it up easily, but it was still machine specific...
this leads me to wonder - has there been a bike design where the rear wheel is allowed to freely "steer" as well as the front wheel? sorta like a crabwalking bike able to side pedal when needed.

Modern automobiles have incorporated rear wheels that turn together with the front wheel (I believe in opposite directions during a turn) in order to decrease the turning circle and improve maneuverability - I'd kill for a bike that has an electro-servo controlled rear wheel that turns to help the biker corner, etc.
The torque is

tau = I*domega/dt

When we have two wheels spinning in opposite directions the torque is

tau = I*domega/dt + I*d(-omega)/dt = 0

The gyroscopic effect doesn't actually make it harder to turn a wheel. It's just that if you turn it in the xy-plane, it automatically turns in the direction perpendicular to the push (the yz-plane). When a human is physically turning a wheel he will try to stop that from happening, thus the feeling that it's hard to turn the wheel. Note that in particular the gyroscopic effect does not produce any force in the direction opposite to the pushing force.

You have a wheel spinning one way, and say that if you try to turn it clockwise in the xy-plane then it will turn clockwise in the yz-plane because of the gyroscopic effect. If you have a wheel spinning the opposite way, and if you turn it clockwise in the xy-plane then it will turn counterclockwise in the yz-plane because of the gyroscopic effect. Adding the two effects cancels them.
Yes, in some sense gravitational attraction carries information about the location of the object.

Yes, Information may not escape the event horizon of a black hole, because to do so would require it to travel faster than the speed of light (up to small quantum corrections)

No, it doesn't follow that information about the singularity is getting out of the black hole. The information got out, and stayed out. The horizon prevents updates from getting out, leaving the previous information and attraction "frozen in" to the shape of space-time.
No they don't. Any spinning wheel will create a force that tries to preserve its axis of rotation. If you have two counter-spinning wheels that share the same axis and try to tilt them, they will both try to preserve the same axis of rotation and thus exert a force in the same direction.
Agile/Scrum/whatever consultant engagements should be measured in hours, not days or weeks. Do a workshop on TDD or optimizing your standups, but if a team is being so badly mismanaged that full-time babysitting is neeeded, they need to replace their management, not add to it.
The Sun, as it is right now, won't have its gravity affect Earth for another 8+ minutes, and the gravity that the Earth feels right now pulling it towards the Sun is actually pulling it towards where the Sun was 8+ minutes ago! (Weird, isn't it?)

I'm almost positive this statement is incorrect.

Relativistic force laws tend to be forced to contain correction factors that ensure that constant velocity motion is "predicted" and the direction of the force is adjusted accordingly - as long as a body is not accelerating, a purely attractive or repulsive force will be pointing at its current position, not its position 8 mins ago.

To see why this must be the case for a repulsive force, at least, imagine two charges riding on frictionless rails that keep them at a constant, finite distance. Suppose they're both moving with some constant velocity (to start, at least) in the same direction - now the place that the force from the other charge appears to be coming from is behind the charge, so if there was no correction factor, each charge would be getting an extra push forwards. This would lead to a runaway "bootstrap" acceleration, and the particles would accelerate to the speed of light. That's a pretty clear violation of the conservation laws, so...

With attractive forces like gravity, there's still a conservation problem, since the charges would slow down to zero speed eventually, but it's always more convincing to cite the runaway solution as a violation of conservation laws than the run-down one, because while the energy could possibly leak out of the charges into the fields, there's nowhere to pull infinite energy from, so it's pretty clear there's a problem if we'd need to.

And this is somewhat different from the runaway self-action solutions that we grudgingly "accept" in E+M, because those tend to involve some limit to infinitesimal size, whereas this is a completely finite situation that we could theoretically set up in the real world with a couple of charged beads or something like that.
Exactly!

Factors contributing to the success of a development project, in decreasing order of importance:

1. the skill of the team

2. the determination of the team to succeed

3. appropriate choice of technologies

4. process

In my experience management agendas are much more likely to interfere with 1-4 than to help. There needs to be some kind of hippocratic oath for development managers and process enthusiasts. Everybody pays lip service to Fred Brooks but people somehow seem to keep forgetting his message.
You cannot really suggest a vi replacement that runs on non-UNIX. Sorry, I'd like to try it out.

I use an F3 as my primary phone. I bought it in late 2006 just to avoid making an investment because there were a lot of rumors at the time about a new phone made by Apple.

One of the biggest advantages for me was dropping out of the feature-upgrade rat race entirely. My phone is exactly as out of date now as it was when I bought it and I expect to have it at least another 10 years. It looks brand new, sounds great, is easy to use and has an insanely long battery life (though a dictionary would be nice!)

It's not for everyone though, and I can see how 'downgrading' might be difficult (especially for addicts).
completely agree that if such a strategy will work it will only work when spending increases the nation's competitive edge: the 1938 counterpart to this was the war where a lot of funding went, it increased technological innovation which in turn positively affected the competitive edge of the US throughout the 20th century.
While I don't agree with the original point either, VC's most definitely hold a leadership position within a company. After all they always a board member and two or three VC's typically represent the majority shareholder block.

I've seen it go both ways. I've seen VC's lead companies to huge exits, as well as lead companies straight into the ground.
Good point, but I'd recommend watching out for mistranslations, otherwise when speaking/writing German, the wrong word is going to come up, and you're going to have to be corrected several times before you are able to naturally find the correct word. In my experience, it's much harder to unlearn a mistake than to learn correctly the first time.

For learning without having to do something else, I'd recommend:

* Turning on subtitles in the target language for all films you watch.

* Listening to web radio when you're walking/commuting (if you have a smartphone/dataplan). Depending on the language, there are even programs in which the reporters speak slowly and provide a transcript (example: RFI français facile for French, Klartext for Swedish).

* Buying bilingual books (where the English is on the left and the other language is on the right).
Ah, it was a popular movie among young guys about ten years back. Actually pretty good and worth watching - it's all about young dudes learning high pressure sales techniques to sell junk stocks.

The "don't pitch the bitch" rule was because women supposedly thought more aboit potential investments and couldn't be coerced into taking risks over the phone. So, in a way, it was more insulting to mens' level of judgment ;-)
Gravity absolutely is affected by gravity. The Einstein field equations are non-linear, so gravitational energy is itself a source of gravity. All forms of energy, and momentum, and even stress and pressure are combined into the "stress energy tensor" which determines the local curvature of space-time.
I just visited the site and scanned it 3 times, couldn't find the price. I'm sure it's there somewhere if you say it is, but I couldn't easily find it. Just a heads up

AFAIK, every startup in the transaction business has had to build it themselves. I suspect it's hard to build without also running a transaction business, because you just wouldn't know what fraud patterns look like.

I've spent quite some time racing Downhill Mountainbikes - and believe me - the gyroscopic effect IS there - and it is very noticeable (DH bikes tend to have MUCH heavier wheels).

Riding lighter wheels has a lot of effect on acceleration and braking. Handling also improves ALOT with lighter wheels.

It also contributes to stability. But you do need to ride faster than this "wuss" (pun intended) moving at snail speed.
Indeed. The site seems geared to linking existing cofounders rather than matching new ones.
By that logic, vi isn't vi enough. Surly you mean a "that does not run on UNIX"
Actually the source is available and quite a few people have made it run on Linux. From what I hear it is still pretty unstable on Linux, but if a few gurus grabbed hold of it, it would probably quickly get up to speed.
> Relativistic force laws tend to be forced to contain correction factors that ensure that constant velocity motion is "predicted" and the direction of the force is adjusted accordingly - as long as a body is not accelerating, a purely attractive or repulsive force will be pointing at its current position, not its position 8 mins ago.

Absolutely correct for E&M. This is because it's a vector field, and the velocity of the source is encoded in how the field moves.

For gravity, it goes one better -- this is a tensor field (hence the notion of gravitons having to be "spin-2" if they were described by a quantum theory), and the acceleration is encoded as well, so you need a non-constant acceleration to notice any difference from the position being instantaneously updated.
Why do people keep putting up Megan Mcardle articles in here? I mean what in the world is noteworthy about this "article"? This is just a rather lazy blog post a little bit of which is a rehash of well known truisms and most of which is a block quote from another blog post.

I was under the impression that tachyons (should they exist) would be expected to give off Cherenkov radiation in vacuum, but I'm not sure where I got that impression.

I hadn't actually heard anything about Mallett for a few years, and I guess this is why. :)
I believe the submitted article gives an example where orbits degrade in just the way you describe.

The canvas version does seem noticeably more smooth in Opera. Perhaps that's just because the balls don't zoom out as much.
I disagree. I've been seeing "Cargo Cult X" comments all over Hacker News recently, usually with several upvotes, and it just annoys me.
They're forgetting it because they want to forget it.

Businessmen want (for reasons that are somewhat rational) to commoditize everything, including labor. Programming labor has been stubbornly difficult to commoditize. Programmers differ in skill in very deep and complex ways, and can't just be swapped out like assembly line workers.

This is immensely frustrating to the bean counters. Anything that comes along and promises to allow programmers to become commodities is going to catch on like wildfire. The desire is too strong from a management perspective. It doesn't matter how many times such efforts have failed in the past. What's old will become new again.
Ask HN: Best online PHP & MySql Tutorials
Hey, I'm a business guy by day and learning PHP by night using this tutorial: http://devzone.zend.com/node/view/id/627

I'll cross reference stuff from that tutorial with the W3 School documents, though I wouldn't really call those tutorials.

This was going fine for me until someone told me the Zend tutorial was old and I should find something else.

I love the fact that the Zend tutorial uses lots of examples and culminates into a few full "apps" at the end.

Are there any other suggestions, thank you:
Fiction: Iain Banks (the bridge; wasp factory; walking on glass; player of games). Ender's game. Asimov. Dostoyevski. Ayn Rand (Fountainhead). Sigurd Hoel. (excellent norwegian writer)

Non-fiction: stuff about military strategy (Sun Tzu, Clausewitz; musashi - the book of 5 rings). Philosophy (zen, taoism; epistemology and philosophical logic). Mathematics.

+ stuff on TODO-list that I have to catch up with.
Not everything is encoded redundantly. Try changing CGA to TGA in one of the exons of PAX6. In humans, this change will result in aniridia, the lack of an iris, an unstable corneal epithelium, and other problems. This is just one example, the one I'm familiar with. There are many other single nucleotide polymorphisms that can cause big changes.
Thanks. I'll fix that.

Geesh.
Boy, I sure agree with everything he says in principle. I certainly prefer to do layout work directly in the XML where possible. But I can't help but wonder if this approach will hamper the Android Market ecosystem. How many great designers out there can work directly in XML? I know there are quite a few, but how many people are they excluding that could otherwise put out some great apps for the market?
The flip side of the coin is maybe it's better to exclude shops that can't work directly in the XML because that will increase the quality of the apps available. Interesting.
It would bend or stretch before it snapped. Nearly all, if not absolutely all, materials that you might want to build a see-saw from will deform before they snap. Maybe it won't deform much, but that ok, and is enough to transmit a push from one end of the lever to the other.

Remember, a lever is just a collection of individual atoms linked together by elecromagnetic forces. You push of the atoms on one end, and they are going electromagnetically push on nearby atoms, and that push is going to propagate as a wave at around the speed of light.
Tiny, pretty unimportant clarification: Microsoft xlsx/docx/etcx files are OOXML. When Microsoft decided to emulate OpenOffice and create a XML-based doc format, they called it "Office Open XML" - or OOXML for short. OpenOffice, on the other hand, uses the XML-based Open Document Format (ODF) for its files by default. Confusing, yes, but there you are.
Yes, I believe it. I've come across the same. But, something to remember, that code was written 30 years ago, and its still running. And the best part, its could be 30 year old code running on the latest and greatest hardware. GoTo isn't the right way to do coding, but at one point in time it was all a programmer had. But it still works, like it or not (maintainable or not).
What if the extension could do the opposite. Translate most of a french webpage into your native tongue but leaving a few French words.

That way you get the correct words for the language you are trying to learn but ignore errors in the language you already know.

Any volunteers to make this extension? :)

I don't remember the last time I touched a unix other than Linux or OSX. I don't expect to anytime soon either. It's not out of prejudice either, that's just what people seem to use for most things now.
