Paying for it was a no-brainer for me. It's an easy to maintain, well designed site and app that's not a another backup black-hole where photos are safe, but too hard to actually look at. That's easily worth a few dollars a month/year.
Even when there's no scaling involved, gamma information embedded in an image can certainly be meaningful. Among other things, they can be used to correct for the fact that different OS's or devices can assume different default gamma factors. Without gamma correction, an image edited on a Mac might look different when viewed on a PC. If the image can tell the browser what gamma factor it was designed for, that problem can be avoided.

Using Photoshop I tried to make my own image like this.

http://i.imgur.com/36EgeOF.png

It's a mix of Tux and the GNU logo.
The strange thing is that Firefox shows Tux, and Chrome shows the GNU logo. Very strange considering both Firefox and Chrome show the pear. My understanding is that the GNU logo (the 'lighter' image) should be shown if the gamma correction is applied. Does anyone know what's going on here?

EDIT: By removing the iCCP color profile chunk, the image displays properly in Firefox.

For anyone interested in making one:

First, I put the two images on separate layers in photoshop. I changed the output levels on Tux to be from 0 to 210, darkening it slightly. I changed the output levels on the GNU logo to be from 215 to 255, making it very bright. Then I used a layer mask on the top layer with a grid pattern to mix the two images. The saved image was a mix of the relatively normal Tux pixels and the bright GNU pixels.

The final touch was editing the gAMA value in the PNG. Using the free program, TweakPNG, I set it to something very low, like in the pear image: 0.02. And that was it!
you know what I didn't see in your reply? All of the large scale coding projects you implemented and put into production for a while. The big problem is that PhD/MS in CS is just an extension of BS, except you now have 4+ more years of bad coding practice under your belt. From my experience, coming out of school people need to relearn how to code in the real world. It is no more assignments you get functional, or in the case of PhD's mostly throw-away software/hacks that does something for your thesis. This is what I mean by skills that I need. Taking a bunch of random classes is nice for you, but none of them teach you how to write code or design systems in the business world. At least bachelor degrees only have ~4 years of bad coding behind them, and they have all of the fundamentals at that point necessary to be great software developers. Adding another 4+ years of bad coding on top of that does not really help you, this is why we pay PhD/MS candidates the same as a BS CS, because from our perspective they are the same!
Ever since watching that Crockford talk, I've wanted to try this out as a Vim plugin.
Exactly. Calculus is not hard. Multivariate analysis is not hard. That's because they are very basic math.

Proving Poincare conjecture or Riemann hypothesis is insanely hard and completely beyond the grasp of us mere mortals.
Maybe, maybe not, that depends on your priorities- If your concern is (or a major concern) is performance, then yes, you should reconsider (maybe look at Go?). If that is not a major concern, maybe not. (I personally am not a Ruby fan due to performance and security issues, but it works well for many people)

No, but the key one is "/* A simple write on the socket ..thats all it takes ! */" which the author said was rather distinctive, and I would have to agree. (In fact, it was the search I used to find this example.)

How it got onto Wikipedie is another question (might have been on en, ru, or other wiki and translated).
Seeing how it's still the most-watched Objective-C repo on GitHub, I'd say it was definitely in vogue at one point. Agree completely with you, fwiw.

He's actually taking a dig at "Quantitative Biology" specializations and saying they aren't really producing anything interesting, so are not worth the trouble.
Why I code
Some thoughts on why coding is important.
You should really understand more than basic statistics for most science. How are you even defining basic stats?
No, real world = in production for potentially a long time, iterated with customer feedback. phd/ms work = functional hacks that maybe a professor or the student ever looks at/codes against and that are eventually thrown away.

except in very rare circumstances
He's not talking about advanced math, he's just saying you don't need to be good at math to be a good biologist. Much like a computer scientist needs to know math, but they don't often need to be that good at it.
I was using "research" in the colloquial sense, not in the "research paper" sense. Bossavit researched the 10x claims (thoroughly and meticulously) and wrote up his findings in the book I mentioned. You can find it here: http://leanpub.com/leprechauns

It's an impressive work of scholarship; many of the citations he followed were out of print, expensive, or referring to unnamed parts of 300-page books. Luckily for us, Bossavit's write-up is engaging and accessible.

It isn't free, but it's trivially inexpensive (US$5-10) if you care about this subject. Far cheaper than the source material.
Derivatives are formulaic. Integrals, like proofs, require thinking backwards, i.e. creativity and/or luck. For the vast majority of people, cultivating that intuition is a lot harder than plugging numbers into formulas...
These three things require wildly different levels of ability: incorrectly using a t-test (e.g. using it in the wrong circumstances), correctly using a t-test, inventing the t-test.

I think Wilson is saying that whilst scientists need to be able to use mathematical tools effectively, they don't need to be able to come up with them.

(Though statistics is probably much easier to use in this way than, say, calculus. Mathematica is very good at differentiation, but I think in many situations where you need to know how to differentiate, rather than just the result?)
The thing that puzzles me is that the image opens in GIMP showing the apple (incorrectly, apparently). I would have thought that GIMP would be entirely aware of embedded color/gamma information like this. (It certainly makes enough of a fuss about color profiles practically every time I open an image!) Is the gamma somehow encoded in a less-standard way, or is GIMP just less clever than I thought?

(My copy of GIMP is a bit outdated, but that shouldn't be a big deal for a basic feature like this, right?)
Later tweets between the two of them show that they were joking with each other, but I guess that doesn't make a good story.

Lovely. There are lots of peripherals from around the same time that I wish were as programmable as the 1541, or even just a little bit. For example, if you'd been able to send, say, 50 bytes of 8085 code to the VT-100, and use a 30-character buffer, you could have handled backspace locally in the terminal, both improving responsiveness and dramatically lowering load on your VAX back in the days when handling an I/O interrupt to echo a character was a substantial load. If the VT-100 or H19 had had 20 bytes of SRAM mapped into its font ROM space, you could have had four programmable glyphs — enough to display a pixel-positioned mouse pointer on top of the text, or really dramatically spice up a lot of video games of the time. (You'd probably want to download code into the terminal to make the animation smooth, although 9600 baud could have gone past 30fps.)

And of course today we have junk heaps full of TVs, calculators, and feature phones that people are throwing out basically because they don't have any way to reprogram them into something useful.

Getting so absorbed in the computer that you are late for dinner would be a bad move. But you seem like a very sharp 15-year-old, so you probably already know that.
Exactly. Everyone I meet in SF seems convinced that: 1) San Francisco is an amazing, modern, international city that is a fantastic place to live; and 2) anyone would be foolish to not live in SF if they want to work in technology.

They are of course wrong on both accounts. San Francisco is a shitty big city, and it is basically the most expensive place to live in the country. I never thought I would say this, but New York is cheap compared to the rent prices in SF. And for what? Shitty un-walkable neighborhoods? Urine everywhere? And everyone has to drive a fucking car if you really want to be able to get around feasibly all the time.

Tech jobs are plentiful in any large city. However, there are plenty of large cities with working public transit systems, decently-well run city governments and non-homogenous cultures that aren't overrun with white/asian males with bad social skills. San Francisco is not one of them.

Which really means: did I spend the time to write good comments?

People will go to endless lengths to make their code more terse and/or "self-documenting", but almost nobody takes the five extra minutes it takes to write an intelligent comment. The comments are far more important.
>>>The easiest way to steal a high end car now is carjacking (i.e. once all the security systems are dieabled); otherwise, you have to either flatbed it or have the right ECU to swap for a specific model. Opportunistic theft of a late-model luxury car is actually pretty hard now.

Well, sadly some 1M owner(s) in the UK beg to differ as can be seen on YT here: https://www.youtube.com/watch?v=DshK4ZXPU9o
Maybe the better solution is to reinforce how dangerous "distracted driving" is, and change the laws so anyone can get in trouble for doing it.

Then the marketing could give examples of what it means to be distracted -- fighting with kids in the back seat, texting, eating cereal, etc.
Perhaps you haven't heard about the doctor who rediscovered the trapezoid rule and had his article published in a respected, peer reviewed biology journal in 1994.[1] The paper is called "A mathematical model for the determination of total area under glucose tolerance and other metabolic curves" — and it got 75 citations (as of 2007). EDIT: Google Scholar lists 178 citations now [‽].
The abstract:

"OBJECTIVE To develop a mathematical model for the determination of total areas under curves from various metabolic studies.

RESEARCH DESIGN AND METHODS In Tai's Model, the total area under a curve is computed by dividing the area under the curve between two designated values on the X-axis (abscissas) into small segments (rectangles and triangles) whose areas can be accurately calculated from their respective geometrical formulas. The total sum of these individual areas thus represents the total area under the curve. Validity of the model is established by comparing total areas obtained from this model to these same areas obtained from graphic method Gess than ±0.4%). Other formulas widely applied by researchers under- or overestimated total area under a metabolic curve by a great margin.

RESULTS Tai's model proves to be able to 1) determine total area under a curve with precision; 2) calculate area with varied shapes that may or may not intercept on one or both X/Y axes; 3) estimate total area under a curve plotted against varied time intervals (abscissas), whereas other formulas only allow the same time interval; and 4) compare total areas of metabolic curves produced by different studies.

CONCLUSIONS The Tai model allows flexibility in experimental conditions, which means, in the case of the glucose-response curve, samples can be taken with differing time intervals and total area under the curve can still be determined with precision."

More information about it is available here. [2]

EDIT: I just looked at the full article and it is more bizarre than I had anticipated. For one, it says that "three formulas have been developed to calculate the total area under a curve", and then lists the works in which the formulas are given. One of the works listed is Irving Adler's A New Look at Geometry, which is a math book accessible to readers with a high school education (it's good book by the way — the MAA has given it a rating of BLL [3]). But Adler's name is misspelled "Alder" in the article and in the citation. The author also gives credit to a doctor at Yale for "his expert review". How embarrassing.

One moderately popular college calculus textbook (by Prof. Apostol of Caltech) introduces integrals before derivatives.
Sorry that it didn't work out for you. I'll put more work into solving this problem, I'll have to come up with a seamless method of merging groups or moving contacts from one account to another.

The problem is described in a support article, as you said: https://fliple.uservoice.com/knowledgebase/articles/182665-i...
"500,000 times faster than its predecessor"

How much power do quantum computers use and when will they be affordable enough to put in a smartphone/tablet?

And why isn't any other company doing this?
Just compare what has been achieved in science in, say, 2000 years before the invention of calculus, with just the 100 years after its invention. As almost always, the author is extrapolating what is true in his field (biology) to "the world as the whole". Biology hasn't historically often used mathematics because it was and to a large extent still is a descriptive science. With molecular biology now being the hottest stream in biology the need for mathematics is much stronger than before even in this discipline.

Instead of denying the obvious, it would be better to think of ways to not scare people away from mathematics - he makes it seem like some people simply do not have the mathematical ability and there is nothing to do about it except finding a field that doesn't need it.
So this looks amazing... and I want to buy into it... but I was just burned by Snapjoy several months ago.

I feel like I'll pay the money... spend my time syncing my library and getting everything organized... and then someone else is going to snatch you guys up and shut it down.

Clearly you guys have a business model and a product you're selling. If I can't even rely on you guys being in business long-term, what can I do? But you guys have built an amazing product! Keep up the good work!

The OP here. I'll explain what it is later if no one cares to guess.

If you're interested in electronics, you probably know its name and purpose, as I did. But it happens to be a little difficult to "extract". I had been meaning to get my hands on one of these for ages. Finally got one!

What's so intriguing to me is that the internal geometry is what makes it function, and was (as I understand it) the genius involved in making the first working version.

A one-year payback time means an IRR (hope I'm using that term right!) of 100%. If you're choosing between putting your money into paying down your mortgage at 6%, investing in the stock market at 3% (plus or minus enormous volatility), insulating your house at 20%, or replacing your old PC router with a cheap MIPS box at 100%, go for the cheap MIPS box!
I agree with dilithiumhe3's idea of getting a teacher or akin to help evangelize your talent, and can be great platforms for personal growth...yea, don't worry about your parents; if they don't 'get it' then you'll just be waisting energy trying to convince them the world isn't flat. Get yourself an adult mentor, preferably one with dot-com scars and/or tattoos, but anyone willing to mentor and stimulate your brain will do. A charismatic mentor is also a powerful weapon upon the wil of your parents, tho only as strong as your grades and attitude so try not to be a punk too much and get any new privileges revoked (that was my mistake). I also wouldn't worry about the computer too much. computers are stupid tools that just piss you off the more time you spend on it. Pickup the Guitar, they're fun to play and the chicks will love you...and you'll also learn a whole lot about structure, composition, analysis - fundamentals of any programing language. Finally, stop sneaking weed and playboys with your friends; go someplace quiet, spark up, and and ponder gravity, or probability, or psychology. whatever stimulates your neurons. The blackhole of adulthood quickly approaches, best set your trajectory early & often.

P.S. _ignore_ the haters! They're NOT trying to change the world, that's why they got time to hate.

Yes, but I believe the stabilizer muscles (rotator cuff) can't continue to support the forces placed on them at a high enough weight. Generally, people "max out" stabilizers before muscles like pecs. So you plateau with dumbbells before barbells.

According to "starting strength", at some point you can't hold the dumbbells due to limitations in grip strength.

I think they're counting the loss of the merchandise. So a chargeback for a $10,000 TV would be like losing $10,000 plus whatever the cost of the TV was for the store.
Sorry about that, you should switch to "all accounts" in settings (see https://fliple.uservoice.com/knowledgebase/articles/155508-i...).
By default it only shows up contacts from the "default account" - lots of people were complaining about seeing duplicate contacts, when in fact they were seeing contacts from all their accounts and indeed they were duplicates.
That's exactly what I was forgetting. Different systems assume different display gammas such as 1.8, 2.2 or sRGB (a mix of 1.0 and 2.4). Thanks!
Amazing that your bike was stolen 3 times and recovered! Only one of my many friends whose bikes have been stolen have ever found it again. Moral of the story: lock up your bike.

Or, if a bike is unlocked in the woods, is it still stealable?
SS suggests that at some point, you simply can't grip dumbbells heavy enough to tax your larger muscles.

I would guess that stability muscles like the rotator cuff will be unable to get stronger at a rate fast enough to tax larger muscles.
It doesn't seem to handle comments correctly. I need to delete all mine to make it work.

It's more like 175 citations now, according to Google Scholar. I've been tempted for years to do some sort of survey of everyone who has cited the paper, to find out (among other things) if they ever took calculus and how this situation could happen.

I've also got Prey installed on my MBP, however for it to "properly" work (i.e. for it to be able to log into a wireless network) the laptop needs to be unlocked after it wakes up from sleep, something i still hesitate to do.

It's a magnetron of course. AFAIK the "warming" effect of microwaves was discovered by accidentally melt chocolate.
He is totally right and I have seen many many examples of it in grad school. The fact is, US's quantitative GRE is a joke even for mid-high school students in other countries. I take it that he says to become a good scientist in many fields, you don't need Tensors, stochastic PDEs, calculus of variations, group and field theory, functional analysis, path integrals etc. You can get by only mastering single variable calculus, statistics and some basic linear algebra.

As former manager of a hypermarket with 170 people team, I need to remind that shop is filming cash registers for many reasons. E.g. to resolve disputes about counting mistakes at the checkout, theft by cashiers, theft by customers.
I completely agree with you. I looked at the site originally, and thought, "eh. another app that's going to be bought out by someone, probably" and left.

After reading some of the comments here, I went back and read it more carefully, and it totally looks like something I'd gladly pay a subscription to, but I've been burned before when places have closed after they've been bought out, it's not a nice feeling.

I'm still contemplating it though! It looks awesome.
So does this mean Shor's Algorithm is going to kick in for real and ruin all our securityz?
you use R?
Quantum computers are still in its infancy, and a lot more work is needed before we can even begin talking about practical, effective use. Consumer market readiness is even further away.

It's probably not worthwhile for quantum computing chips to enter the consumer market, because (AFAIK) quantum computers are only very good at solving a very specific set of problems (e.g. integer factorization), but their advantages over classical chips diminish (or even become negative) for general purpose computation. Of course as quantum chips develop, quantum algorithms will develop/evolve with them so that might change.

There have been some skepticism over whether their quantum computing chip (and similar ones that other companies develop) is actually a quantum computer (e.g. whether true quantum entanglement was observed).

There are other companies doing this, such as IBM.
