I just watched that video and I'm incredibly upset. I'm currently teaching math at a high school that is on "priority improvement" and needs to reach impossible goals this year or face a "take over" by the state. Our curriculum is the Core series of math books that is incredibly word heavy while we have a student population that can't read that well and is primarily ELL. We have been told it is a directive that we must use the book in class. Every class period, all class period, which is 58 minutes. I had to do training on Saturday for six hours regarding our use of the book in class. They've been using these books for the past few years and it hasn't worked, in fact we need even more growth this year than was needed in the past to get out of priority improvement. Instead of changing the curriculum to include ideas like the ST Math program they're essentially threatening our jobs. There has to be a way to get these products into more classrooms like ours.
Is it possible to do this if you use Amazon SES? IIRC you have to validate every address you use to send outbound mail.
Maybe the source is not special or unique, but not everyone wants to give away their work. Eg you just spent 6 months developing a product feature and by coincidence your competitor also launches the same feature 2 weeks later :|

Of course minified code is also usable, however it makes things just that little bit more difficult for rip off artists.

I'm all for free and open software, but some aren't, and they're free to feel that way.
the CBC comments section is heavily censored? Looking at it I didn't think they even had moderators.
I have some teenagers working with Python on Nuuton and you might feel at home with them. They are building the main search crawler, and some of the APIs, so its also a cool and interesting project for you.
Send me an email (address in profile). If anything, I can at least point you in a good direction.
Also amazing, was the materials engineering. SR71 ushered in the use of widespread Titanium in the airframe, which was needed to stand up to the heat (friction) at Mach 3+. Because of the severe heat-cycling, the engineers ultimately figured out an unorthodox solution to manage thermal expansion:

The fuselage panels were manufactured to fit only loosely on the ground. Proper alignment was only achieved when the airframe heated up and expanded several inches. Because of this, and the lack of a fuel sealing system that could handle the thermal expansion of the airframe at extreme temperatures, the aircraft would leak JP-7 jet fuel on the runway. At the beginning of each mission, the aircraft would make a short sprint after takeoff to warm up the airframe, then refuel before heading off to its destination.

Posting this because some people seem confused about IR.

I'd just like to point out here that infrared is a really wide chunk of spectrum. It goes from 0.74µm to 300 µm (according to Wikipedia), which is a factor of about 400. By comparison, the visual spectrum has a width of about a factor of 2, and yet our biology still gives us four different sensors crammed within that little sliver. Imagine if you had a rainbow with red, orange, yellow, green, blue, indigo, violet, and 50 more colors which were just as distinct from each other, and you get an appreciation of how big IR is.

Near infrared is the stuff used by artistic IR photographers (film and digital), remote controls, and night vision cameras. Regular CCDs designed for visible light also pick up near IR, so most cameras have a built-in filter which blocks it out. This is what you remove to turn your camera into an IR camera, and it also accounts for why some things just show up wrong in some digital pictures. Maybe you've seen a fireplace with purple flames -- that's because the IR filter isn't getting rid of all the near IR.

Near infrared is really just light that you can't see. Most things don't emit near infrared unless they're very hot (like fire) or designed to do so (like LEDs).

Far infrared is used in thermal imaging. It is a completely different beast, with much longer wavelengths.

1) Thermal infrared is low-resolution. The resolution of an imaging system is limited by the aperture of the lens relative to the wavelength of light that you are using. A proficient photographer with a nice prime lens and a tripod can come close to the resolution limit of visible light with no trouble, but the (much) longer wavelength of far infrared means that the relative size of a lens is much smaller. You simply cannot get a sharp picture of thermal infrared due to the increased diffraction.

2) Thermal infrared requires different sensors. Your standard CCD simply does not pick it up, you need something like HeCdTe.

3) Thermal infrared requires different lenses. Far infrared does not pass through glass like it does through air, you need to use a different material to make the lens, or just use a mirror.

4) Thermal imaging is more sensitive to thermal noise. That's why you cool the sensors. All sensors have thermal noise, even visible-light sensors. You will get cleaner pictures by refrigerating your visible-light CCD too, but it's a much bigger deal in far IR.

5) Atmosphere absorbs IR. Well, not all of IR. But the atmosphere is fairly opaque in some IR bands. If you build a sensor at 6-7µm you might as well submerge the thing in pea soup, the atmosphere is that opaque.

So [near] IR photography and [far IR] thermal photography are completely different beasts.

No; Jan van Eyck painted the way he did in large part because that is what he was expected to do; 'Art', for him, in his time, had a fairly specific definition.

It is the lack of such a definition that makes postmodernism.

If someone painted like Jan van Eyck today, it would be postmodern --- both because of the year, and because of the current culture of art. Same painting, different classification. (There's a hilarious story by Borges with almost exactly this premise: "Pierre Menard, Author of the Quixote")

Please understand refraining from saying whether this freedom is good or bad. I mean only to name a distinction between western art up through modernism -- art which met specific expectations according to period and place --- and western art post-modernism, which defies any uniform expectation.

I know several people who are amazingly talented writers who've been unable to find paying work. Writing prose is sort-of like software, in that you can get a lot of practice in before you ever get a job, but it's hard to prove that your practice was valuable until you've had a few years of professional experience.

As a fellow female in technology, I just want to say you are a beautiful woman (not that it's relevant or if that matters or anything, I just feel like I have to say it) and your amazing contribution to the field as well as your humility despite all that is incredibly inspiring.

So, I don't think it's unreasonable to try and lower barriers for women who choose to go into tech. (I don't think it's unreasonable to try and lower barriers for anyone who chooses to go into tech, but like you say, targeting women affects 51% of the population, so it has a pretty high return on investment.) I think it's worth supporting our female colleagues, and celebrating what they achieve. (FWIW, a friend of mine has a blog that does precisely that: http://techladyallstars.com/)

I object to framing the debate as a "handicap", because I've found that whenever you start identifying something as a handicap it tends to become one. (Edit: shit, just reread the thread and I did that. Poor word choice on my part.) My own experience is race; my father was sure that the reason that he kept getting passed over for promotions was because he was non-white, and as a result, he ignored all the other possible reasons that were under his control. I've been very careful not to identify myself in racial terms since, because I don't want to give those stereotypes power over me.

I read Kathy's account of being oblivious to all the little microaggressions going on around her. I explicitly made a different choice: I knew from the beginning that there may be people who see me as "just a programmer" or "not leadership material" or "socially awkward nerd" or "undateable" because physically I look Asian. And so I figured I'd work on the parts that I could change, and everything else is somebody else's problem. They're entitled to whatever preconceptions they have; if that's a problem, I can go find other people to interact with.

I really like that Kathy came here to clarify that she was sharing her personal experience, just as Laura shared hers, and now I'm sharing mine. Isn't the meta-problem here that we don't see each other as individuals, and that it's all the "1%" and the "99%" and the "51%" and the "49%"? And I think that if there're specific policies that make it easier for 51% of the population, that's a good thing. But that doesn't make it a handicap, nor should they be a protected group exempt from the same standards we apply to anyone else, nor should we forget that there are all sorts of other axes that we can categorize people by, and some of them have it a lot easier than others.
Agree! Just read up to page 38 and realized there wasn't a single insightful thing he'd said. It seems to be all about him and yes, it is very, very, very wordy and poorly formatted!
Not really. I could say that talking about kittens is like yelling fire in a crowded theater. The fire-in-a-crowded-theater argument is not diminished because I did a bad job of lining up reality with the analogy. The problem comes in when people are allowed to say, X is like ..., without X actually being like that.
I suppose that by hedonism you mean materialism, and I get your point. What I was trying to say is that it's tempting to believe that some kind of ancient wisdom could guide your life (indeed I'm sure Tim Ferris doesn't believe it himself, but some readers might). But ideas are reactions to a very specific reality, and even in the context of this reality these ideas didn't work. It doesn't mean that there is nothing valuable in the stoics' writings, just that using these thoughts as a "Personal Operating System" is as useful as installing MS-DOS on a smartphone

"The simple lesson here is that if you want to stop non-believers from doing blasphemy, violent reprisals work."

And it's the wrong lesson learned. Violent reprisals didn't happen as a result of blasphemy, but of murder and occupation and dominance.
From Löb's theorem to spreadsheet evaluation
> Militant Islam scares the crap out of the West, and we're willing to pass laws and endure a certain level of self-censorship to avoid provoking violence out of these people.

This is such a stupid strategy. The right thing to do is to look at the root cause of all this. After all, there are lots of angry people all across the world that hate the Western world and want to hurt it, but most can't. What sets the Arabs apart is their vast oil riches. Without that, they wouldn't have the money or power to do anything to the West.

If you want to fight militant Islam, the first thing to do is to limit immigration from those countries and spread the immigrants out to force assimilation. The second thing to do is to invest as much money as possible into developing domestic energy sources, as well as alternatives to crude oil. The minute that crude oil loses its relevance to the Western world, the Arabs will just go back to what they were before - a bunch of desert nomads with no real power.

Contrary to what people here tell you, its not so easy getting pad anything above $50/hour as a freelancer. Its possible (I charge more than that and have a healthy stream of customers), but it takes a lot of marketing in your part. If you can't market yourself, then you are better off charging less. In fact, I've been thinking about lowering my prices in order to have more time for other projects (most notably Nuuton).
"It appears that the one thing modern society can no longer tolerate is intolerance" Sounds like a self defeating argument.

There's a lot of investigation that has been done around ADHD and the ability to "hyperfocus". Dr Russell Barkley has an interesting insight on this phenomenon.

http://www.youtube.com/watch?v=Yfkg0VWx3rM

I'm not certain that I agree with him in full. I was diagnosed with ADHD when I was in my early 20s. The ability to deeply focus on a project was helpful to me as well. I certainly don't think that we can call it a "cure" for ADD, but it can absolutely be a positive byproduct.

"Let sleep not come upon thy languid eyes
Before each daily action thou hast scann'd;

From first to last examine all, and then
Blame what is wrong in what is right rejoice."

Huh.

I'm actually getting tested for ADD on the recommendation of my therapist (the preliminary answer seems to be that no, I do not have ADD). I most emphatically cannot work while I have a TV running. In fact, I can't even seem to program and listen to music at the same time.
Perhaps Louis CK can explain it in a way that makes it make more sense to you: https://www.youtube.com/watch?v=TG4f9zR5yzY

It's not about denigrating anyone's achievements. It's about understanding that some things make your life easier. Being born straight, white, and male, in the United States (or other first world countries) provides a tremendous amount of benefit to you. To deny that benefit is to deny reality.

It doesn't mean when you do something good it doesn't count...it just means that you probably would have had a harder time had you been born non-white, non-male, non-straight. No one is saying you're bad for being white, male, or straight, or that what you accomplish does not count.

Denying you receive privileges for being a straight white male can be offensive or upsetting to those who don't experience life with those privileges. It's a complicated issue, of course, and there are plenty of straight white males who have to overcome significant hurdles; but given the same circumstances, the straight white male has an easier time getting ahead in business (especially tech and science), being treated with respect, not being treated like a child (women are frequently treated like children by well-meaning men), and not being treated like an outsider.

You're not being blamed for being born lucky. You're just being asked to acknowledge it.

The thing that worries me with that approach is overzealous "add to address book" functionality. I don't want to be clicking "John Smith" in some dropdown and have it go to some noreply address at some third party.

Your analysis of his comment is overly charitable. He did not question anything. He stated his opinions without backing them up with facts.

I'm sure there are plenty of studies about the rates at which gender-related behaviors are considered inappropriate. Sexism isn't a new issue. Universities have entire departments dedicated to this sort of thing.

I have the same sort of reaction to Piazz(z)a, and I think they try the solution you propose. I think it's because I perceive Piazza as encouraging the course staff to send more emails than they otherwise would. This may or may not be true, but I subconsciously think it is.

It _is_ true that I get more random invitations to things I only slightly care about via social media, and those rare invitations I get by actual personal email tend to be things I strongly care about. So the argument can be made that Facebook and G+ _are_ spamming me, by encouraging my acquaintances to spam me.
My school has recently switched from a branded variant of Blackboard, to Desire2Learn which bills itself as open, etc. From a student perspective, the usability is not much different.

One "feature" that drives me insane is it creates zips on the server side every time you download a file (e.g., lecture slides, PDFs) even if the download is only one file. Effectively blocks one from using it on an iPad.

Thanks for the write up.

Can I ask, how much do you think the non-ability to focus on a task it is about procrastination and how much is about your ADD?

For example, I am doing my PhD now, and find it very hard to focus on actual research, instead losing time to procrastination (I'm looking at you, HN!). After hours, I also tend to have several different projects running at once, for which I struggle to prioritize and get any single one finished. However, when I'm at my paid job as a developer, I focus just fine. Given the other anecdotes here, I would expect a clinical diagnosis would show that I have signs of ADHD, but I would attribute them to laziness on my part.

I don't want to comment on your case specifically, but my fiancé is doing her PhD in psychophysiology, and more specifically, natural treatments for ADHD, and there is certainly a perception that ADHD is somewhat over diagnosed. I am interested if you would have attributed a different name (e.g. procrastination) to some of the behaviours you discussed before hearing about or being diagnosed with ADD/ADHD.
