I'll echo what some of the other say here - the Ubiquiti hardware is quite cheap, and well made.

However, they're often led down by sub-par software.

For example, I've bought several of the Unifi AP's, and the firmware and controller were pretty buggy for quite a while.

Recently, I've also purchased several of their Unifi Video surveillance cameras. With these, you need to use version 3.0 of their controller software.

However, this controller software is incredibly buggy and unreliable - look at some of the posts on their own forums:

https://community.ubnt.com/t5/UniFi-Video-Beta/bd-p/airVisio...

Oh, and did I mention, the promised mobile functionality (i.e. viewing the video on your mobile device) doesn't actually work at all (and never has) - but it will apparently be fixed "very" soon.

Ubiquiti also aren't great with release dates - e.g. they promised a native UVC app, which has been delayed for some time now.
Antico's painting of an eucalyptus doesn't "give us a hint of the extra shades she is seeing". It's just another instance of the [El Greco fallacy](http://www.huffingtonpost.com/wray-herbert/a-new-look-at-per...): art historians used to think that El Greco's elongated figures were a result of his having a severe form of astigmatism. But, of course, if that had been the reason, he would have also seen an elongated canvass when painting, with the net result of figures painted in standard proportions.

Here as well, if the tree painting was somewhow a reflection of Antico's tetrachromatism, she would have chosen colors that matched those that she sees on the eucalyptus. Such colors would be indistinguishable to us trichromats from the colors the tree does have, with the net result of a normally colored tree painting.

At best, Antico is using something of a metaphor to convey her tetrachromatism. But no real insight on her vision.
The bottom line is: If you're easily replaceable, you will feel the squeeze sooner or later.

Been in those kind of jobs myself and the only way out is to upskill until your value as a worker is high enough that ruthless managers that couldn't care less about the impact of their decisions on individuals won't get away with it.
The funny thing about these articles is that they usually oversimplify the problem. For example, they treat time as an absolute. They discard the influence of timezones, daylight savings vs std time, length of the daylight. At least in this article they acknowledge existence of different types of people.
The title is a little misleading - perhaps better would be "A very limited subset of Regular Expressions in 100 lines of Scala".

While the code is concise, this is more a case of "it implements A and B of an X" than "it implements an X, apart from A and B".

Still, all three parts of the series are a good read, and definitely helpful for learning about parsing and about Scala.

State Machines, as you noted, are easy to do with C. I think the added value in this respect is that this makes it much easier to manage the State Machines. I often hear guys at work complaining about how they'd like to switch to using an RTOS because the codebase is a tangled mess of State Machines (not that the two are mutually exclusive of course). Having said that, I seem to remember there is a tool dedicated to creating State Machines that compile down to C - the name escapes me however.

Why? The preprocessor is a huge hack that is mostly obsolete. 99% of my programs only use `#include` and `#pragma once`.
Google's implementation is carrier vetoable, since it's on the SIM.

Additionally, Google's implementation requires the transaction transit their infrastructure, Apple's does not. They don't even know the transaction occurred.

Yes, they're not technically first, but the two systems are not identical.

Personally, the less a large corporation knows about me, the better.
This is clearly aimed at applications that must be very reliable, e.g. life-critical applications like cars (note BMW sponsor it).

Most embedded programming isn't that bug-sensitive, but quite a lot is and I'd wager they'd love something like this.

I know I'd use it if I were writing safety-critical code.
The card details were stored on the secure element but the pin was not and because the authentication is not done using the secure element it is trivial to bypass:
http://cybersecurity.mit.edu/2012/10/google-wallet-overview-...

The current implementation of Google wallet stores your card details in a google server which protects against these attacks but is not a viable business model (google are making a loss on every transaction since they pay it and then bill the customer themselves).

If you want to look into it, the field that studies these things is called "public choice theory". It basically boils down to the fact that concentrated interests can impose diffuse costs (which they partially harvest in the form of rents) quite easily.
Apparently it does.

Great article, I love his detailed explanations of why he does things the way he does them (the boots without laces, the natural fibers) when it comes to safety.

Don't be fooled by the low-tech appearance, this guy is top notch, he's been doing a ton of research and has quite a bit of experience. You don't set this up the first time out of the gate like this and if you plan on doing any aluminum casting yourself this would be a great starting point.

I also like how he evaluates what he's done, notices what could be improved and makes notes to do those things better next time. That's how you get to where he's gotten in the first place. There are other aluminum melting tutorials out there that make me cringe.

If anybody is wondering why concrete can explode when heated rapidly, concrete will always contain a percentage of water and when you heat that up faster than the steam can escape from the material it will cause a steam explosion.
This is called "Nutritional epidemiology"[1] and there are quite a few really big studies already done about this[2][3]

You are incorrect about that, and Randall’s drawing is misleading you (it shows the gamut boundary of an RGB cube, rather than the full three-dimensional color space he asked about in his survey).

For people with “normal” trichromatic color vision, the color we perceive when looking at a particular spot does indeed fall into a three dimensional “color space”. You’re right that without careful attention/training it’s hard to state colors in terms of coordinates in terms of cone cell responses directly or color opponent signals (blue–yellow, red–green, white–black). It’s easy to train someone to give reasonably accurate color coordinates in terms of lightness, hue, and chroma, however.

If you want to understand human color vision in detail, I recommend this online resource: http://www.handprint.com/LS/CVS/color.html

There is an odd contrast between this article and the announcement in January of broad support for VP9 from hardware manufacturers:

As Google announced today, however, virtually all major hardware vendors will soon support VP9 natively in their products and allow Google’s YouTube to stream HD content up to 4K directly to computers, TVs and mobile devices.

These new hardware partners include ARM, Broadcom, Intel, LG, Marvell, MediaTek, Nvidia, Panasonic, Philips, Qualcomm, RealTek, Samsung, Sigma, Sharp, Sony and Toshiba.[1]

I wonder if the VP9 situation changed for the worse since January, or if the article is simply misleading. It's hard to tell as the quotes in the article are mostly anectodal.

This has really nothing to do with js. I could mechanically translate the demo to Haskell or Python and it would perform equally well, as all the heavy computations are done on the graphics card and those are given in a C like but implicitely parallel shader language. All this really demonstrates that the webgl bindings to opengl have minimal overhead. One thing that is impressive, how you can trivially and more or less declaratively define a user interface using the browser rendering engine, whereas a similar user interface in a simple opengl demo would have to be very primitive or use a third party library. This makes such webgl demos much nicer to interact with compared to a similar demo written in c, but the actual code is nearly the same, since it is mainly library calls to opengl.
Hmm... is there any relation to mbed.org ? mbed is a new methodology (supported by ARM) for programming and debugging embedded devices through CMSIS-DAP.
The gene for the “short” wavelength cone† is located on chromosome 7, whereas the genes for the others are located on the X chromosome. Since females have two X chromosomes, it is possible for them to have 2 variant copies of the long or medium cone genes. (Since males only have one X chromosome, color vision deficiencies caused by a missing or abnormal copy of one of the medium/long cone pigment genes are much more common than for females.)

It would certainly be possible for a genetic mutation to result in an extra mutated copy of the short cone pigment gene, but I don’t think I’ve heard of variants of this gene with slightly different light sensitivity than the usual type (they might exist though?). By contrast “non-standard” version of the medium cone pigment gene is relatively common.

See:
http://ghr.nlm.nih.gov/gene/OPN1SW
http://ghr.nlm.nih.gov/gene/OPN1MW
http://ghr.nlm.nih.gov/gene/OPN1MW2
http://ghr.nlm.nih.gov/gene/OPN1LW

† We should properly refer to the cones as long, medium, and short rather than red, green, and blue, since color is computed from differences in cone responses.
I, for one, can completely understand the feelings of frustration behind the statement. Also note how forcefully arguing positions managed to derail the entire thread above into unnecessary bickering about what basically amounts to a matter of nuance (as happens so often in discussions about NSA scandals, hence the frustrations), while this cheap shot, in fact, did not. Quality of discussion, you be the judge.

I get your point about remaining civil (though I disagree that stooping to lower levels always weakens one's arguments), and I commend you for taking such a proactive role in this, I really do. Sometimes though, discourse here has different problems than strictly has to do with civility, when I open a thread about yet another NSA scandal and I see tptacek pushing the very same hot button again and again, derailing all top discussion into something that has little if anything to do with the topic. Yes sure he is often technically correct, but he's a smart guy (really smart, and that is when I'd expect better, wouldn't you?), knowing very well that what and how he writes makes people think he's defending the NSA somehow. Somebody will engage, and the by now very familiar pattern unrolls in the same way it always does, taking up parts of the thread-space that could've been useful and interesting discussion. He could also make the same statement in a much less inflammatory way. Or simply not at all, because in this particular case he was pre-empting a sentiment that nobody actually claimed.

In short, I don't think forcefully arguing their positions would have addressed the frustrations that gave cause to coldtea's "cheap shot" (I can't really speak for him of course), but rather the opposite.
It's hard to compress what's known about the subject of color perception differences among people with nominally normal color vision.

Hypothetical tetrachromacy has been demonstrated, that is, M and L cones with minor differences in peak spectral response existing in a retinal mosaic. The question arises whether this difference is capable of being propagated through the bipolar connecting neuronal paths (which form the "blue-yellow" and "red-green" channel paths conveying color info to the brain visual cortex).

Several studies found no evidence for a "fourth channel", and some perceptual studies did not show confirmation of tetrachromacy. However a couple of studies do hint at rare female subjects who do seem to have good evidence for this trait.

It is postulated that because of the differences in the exact genetic encodings on the 2 X chromosomes in females, that up to 50% of women have a retinal mosaic of 4 populations of cones, S M M' L, S M L L', and so on. The theory is that this allowed greater distinction of yellow to red color distinction which may have helped survival by avoiding toxic plants based on subtle color distinctions.

In art, there are great colorists and those who are virtually incapable of subtle use of color. If anyone interested in finding out about their own abilities, check out:
http://www.xrite.com/online-color-test-challenge

The on-line test is only a rough estimate, but it's fun and challenging. I suspect there's a spectrum, aka normal distribution of color discrimination ability. I should't say how well I did, though the results of trying it several times were remarkably consistent despite different computer systems that I used.

BTW I encountered one very intriguing article reporting on a large sample of retinas obtained post-mortem. As expected, ~50% of females showed retinal mosaic of 2 M or L cones where only one each was expected. Most fascinating was the fact that of male retinas 8% showed a similar tetrachromat pattern. How that could arise is a mystery considering males have only one X chromosome. (There are pigment gene variations with greater number of CNV and TR which could be activated? But it's still a mystery.)
Macros used right can really help to clean up messy code and/or reduce repeating code to something clearer (e.g. in crypto-code).

He mentions Gingery as an inspiration:

"The project that I am gradually preparing for is to build the Gingery Lathe. The late Dave Gingery wrote a seven-part series of books in which he describes how to build a foundry, lathe, shaper, drill press and other metalworking tools from scrap at a tiny fraction of the cost of buying each. For me it’s not so much the cost savings (or the post-apocalypse skills!) as it is the opportunity to learn for myself how tools work at a fundamental level."

From the comments.
With Android's >80% market share and iOS' approaching single-digits, that's a pretty safe assumption. I hope to see more balanced numbers in the future (preferably including something less proprietary) but for now we have one very clear winner in this race.

This is a case where an article's title, rather than distorting an article's content, makes a claim not supported by the article at all.

In a telephone conversation, we link two brains by way of sound waves. A text-based chat uses light waves. A video call uses both. This experiment uses electrical stimulation of neurons, but in all these examples, well-understood physical methods are used to transmit information from place to place -- it's not telepathy as that term is defined.

http://en.wikipedia.org/wiki/Telepathy

Quote: "Telepathy (from the Ancient Greek τῆλε, tele meaning "distant" and πάθος, pathos or -patheia meaning "feeling, perception, passion, affliction, experience")[3][4] is the purported transmission of information from one person to another without using any of our known sensory channels or physical interaction." [emphasis added]

How is electrical stimulation of neurons not "physical interaction"? Is execution by electric chair defined as telepathy?

The question arises whether this difference is capable of being propagated through the bipolar connecting neuronal paths (which form the "blue-yellow" and "red-green" channel paths conveying color info to the brain visual cortex).

Adding genes for extra cone types into normally dichromatic mammals (mice or something? I don’t remember off hand and I don’t have the citation at my fingertips) has seemed in studies to result in trichromatic vision, so it’s not too big a leap to suspect that tetrachromacy of the type described in the article might happen for some humans.

As you say there hasn’t been any study which showed this conclusively (that I’ve seen anyhow). I’d love to see more thorough research on these subjects who supposedly possess such vision.

Note, this online test is a bit easier than the paper version of the Farnsworth–Munsell hue test, since the colors in the screen version end up with some lightness differences that make it a bit easier to keep some sections of the chart in order. Either way, the test IMO mostly measures (a) whether someone has “normal” trichromatic vision, and (b) how patient and willing to fiddle with fine details they are. I don’t personally think Farnsworth–Munsell test scores are super meaningful, though a very poor score does indicate some color vision deficiency. [FWIW, if I take the time to do the test slowly, either on screen or on paper, I consistently score ~0, occasionally mixing up one pair or another.]

But anyway, I think the ability to be a good colorist in art has a whole lot to do with practice. Spending a lot of time mixing paint or color correcting photographs is likely to heighten awareness of tiny distinctions. For instance, I know that after a couple years of photography courses, several of my friends got much better at noticing color casts in photographs. Not that they couldn’t physically see them before, but after experience they more often spontaneously noticed the casts and started to have a feel for just how much adjustment in which direction would be necessary to counteract them.
Well he decided to take mushrooms one day due to peer pressure. Unfortunately he didn't know that he had a few problems that hadn't manifested themselves yet. The mushrooms pushed him over the edge and within a couple of days he became increasingly violent and had random personality changes. This was merely after one single session.

Consequentially the chain of events is pretty obvious but ultimately everyone kicked him out, especially his girlfriend who couldn't cope with him kicking the shit out of her randomly and then being completely normal 20 seconds later.

Eventually they managed to help him get control over it with a cocktail of drugs but he's not the same now. The drugs they give him take away most of his good traits as well as the bad ones.

A shell of a human for the sake of one mistake.

Not saying the problems may never have manifested themselves at all but the sudden change was unbelievable.

Being 100% honest, I did some experimentation back in my student days and was damn lucky. Now in my late 30s, people who stayed with it aren't the same anymore. It's destroyed them entirely. I'm sure I'll get some 20-year old jump in now and say that smoking hash is fine but it's not - you won't know it until you're that fried person in your 30's and it's too late. One of my friends got a first in his degree (electrical engineering) but is so fucked up now from just smoking pot that he can't even hold down a job stacking shelves in Tesco.

All I see is self-destruction and it makes me very sad and angry.

Edit: I expect downvotes as you can't have rational discussion with the pro-drugs crowd on the Internet. I'm not interested in your opinion; experience says the opposite and your lack of experience says otherwise. Even the fact I have to suffix the post with this shows the sad state of affairs.

This is exactly the reason why it should be legalized. To allow for careful monitoring and warn risk groups. It's not hard to get such stuff anyway, so why not do it in a controlled fashion.
It was said by Jim Rohn.
Had a relative that was given intravenous penicillin by a GP and it almost killed her. Knew a guy once that almost died by bee stings. Had a friend in school who started smoking pot at age 12 and it destroyed his life.

Life is about risk, and everything we ingest has the risk to do terrible things to us. You can die from too much water. So the question isn't whether things or good or bad, rather who gets to assess the risk and what tools do they use?

Would I want my 16-year-old assessing the risk of magic mushrooms? Hell no. Would I want my drug addicted 35-year-old cousin? Yeah, probably. So the real question is who gets to decide. And why. I'm completely comfortable with some kind of psyilocybin addiction treatment coordinated (but not approved by) a GP or LCSW.

I also would rather not flip the coin on drug use, including a fair number of prescription drugs. But as a voter I remain convinced of my right to change my mind and not have others make that choice for me. The problem we're seeing now, that is only just getting started to be addressed, is that vast numbers of chemicals have been off-limits for even scientific exploration of benefits. That means nobody can assess the risk -- of things that might have great benefit to mankind. That's whacked.

I'm a printmaker (among other things), mostly making monotypes in recent years. The technique allows subtle color transitions which I deeply enjoy, and I notice particular pleasure of the visual effects of colors that range from green, yellow-green through orange and red.

I've discovered that many art colleagues "don't get it", i.e., who seem not to discern the same subtleties that I appreciate. I'm beginning to think this may be due to differences in color discrimination. IOW whatever the basis for the difference I'm sure it would be measurable within limits of color vision test resolution.

I don't know about the illustration in the article. Reproduction (especially reduced resolution) may very well coarsen the color so that the distinctions are run together, so no difference to see. You might want to try the on-line Farnswell-Munsell 100 test alluded to above which might be more informative.
