Millimeter wave scanners are of an entirely different kind of 'radiation' than backscatter X-rays in the same way 'red light' is of a different kind of radiation from 'alpha particles'. Yes, technically they are are the "radiation" of an emitted particle from an interaction. But they are of significantly, quantitatively, and oncogenically different kinds of 'radiation'.

Backscatter X-ray radiation is of very high intensity and almost certainly can cause damage to biological surface tissue. Millimeter wave uses non-ionizing radiation - it does not have the capability of causing what we generally refer to when we speak of biological damage by radiation. It might do something else - though this seems to be debatable, and largely hypothetical, it is simply incapable of the damage that a backscatter X-ray machine could realistically cause.

Here's the letter authored by significant scientists written to the White House in regards to their thoughts on the backscatter machines [1].

I wish more people knew this. Even if you beat the odds and the startup you work for goes places, you may only get 10%-15% of the proceeds now, and be hoping for the rest even further out in the future. Almost certainly better to just work for a public company from the start.

Similarly python throws an exception, and I bet other languages have their own behaviors, but in case of C this is the only way (or at least it is the only non complicated way to do it).

When I read this article I thought it was preaching to a choir. I'm actually quite surprised people programming C don't check for errors. That's the only way the functions can provide a feedback.

What I think would be more interesting would be a way for viewers to stimulate the fish.

Say you have a link that charges the viewer a small fee to feed the fish on a certain side of the tank. Scale the price with how much food the fish has been given (all the way down to $0.00 and up exponentially to not overfeed the fish). Basically, let the internet handle feeding your fish.

So they can watch it play street fighter.

And you make money off of it.
Nope, it won't quit. In failure fork returns -1, what's still true...

But the forked processes will quit as soon as they are created. Thus, it won't work anyway.
Maybe you should include lots of faces? And check that you're doing sRGB gamma math correctly. http://http.developer.nvidia.com/GPUGems3/gpugems3_ch24.html

Edit: I'm guessing convert("RGB") means convert from whatever to linear RGB? So that part should be fine.
We don't have one of those machines to test on, so we can't say for sure.

We think it's likely that they went through the same sort of evaluation process that put the Secure 1000 into service, and that they should be publicly reviewed by independent researchers.
That's pretty good foresight by whoever designed them.

> But when you move from the monolithic CMS to an architecture of small apps, there is no need for The Big Rewrite.

Uh, what? Maybe if your app is written The Right Way, but in cases where encapsulation and cohesion are poor, where do you begin splitting? Services, on the other hand, force encapsulation from the get-go. Why wouldn't it be easier to connect them -- it's what they designed to do.
Wow that's a really wild story, but I think it's also pretty different. fork() returning -1 is defined behavior, as is true for many functions. Whereas not having stderr open defies everything about the C standard I/O. (K&R B1, 7.5 & 7.6)

Note however, that strictly speaking stderr does not have to be 2. It can be any number, but it has to be whatever the include file says it is, so if you don't specify the stream as stderr but instead write to stream 2, that would potentially be a problem.

That said, if for some reason you have a program completely defying the C standard, you can test whether the streams are open (and they are explicitly defined as having to be open) using fcntl and testing for EBADF at the very beginning of the program.
who had drugs shipped to him...(he was uninvolved)

"had drugs shipped" is a little ambiguous: someone shipped drugs using the mayor's house as the destination; Mayor Calvo had no knowledge or involvement in this. Despite his lack of involvement, the SWAT teams shot both of his Labrador retrievers, including one that was fleeing.

Its real tough to be a solo founder and you need somebody with different skill sets to augment your own and to keep you on track.

I met one of my cofounders on Angellist.com and the other on CoFounderslab.com.

You are equating basic competition with the tragedy of the commons. Even if it were a zero sum game (which it is not) it still would not be an example of the tragedy of the commons. The tragedy of the commons is when individuals have the option to consume, but do not have to bear the cost. They then choose to over-consume because they have no incentive not to. In your example the people who work 80 hours to afford a house, have to work 80, thus bearing the cost themselves.
A general policy of mine is to avoid people who are frequently bad-mouthing other people. I think this is your key indicator of his character, and yes it does make for a hostile, and corrosive, work environment.
What should you get from an Error?
I don't think controlling for "ability" would affect the results or conclusions if we assume that "ability" is not set at birth. I think there is a lot of reason to believe that, given that much of "ability" seems to have to do with internal features like grit, empathy, and patience. These can (probably) be enhanced by good parenting and environment or detracted from by bad parenting or a chaotic or violent environment. (See John Medina's Brain Rules for Babies for a good summary of existing evidence)

Of course, if these results are just the natural result of genetically hereditary features like intelligence than the conclusions are insanely gloomy- due to the "assortative mating" trend cited in the article, the US seems to be doomed to have hereditary social stratification.
(And the queries that are speeded up by this optimization are probably the _fastest_ queries in your app to begin with--simple one column lookups on one table, including probably most commonly lookups by pk. I am definitely not assuming this will make any measurable performance difference to real world apps. Although it may. I don't know if anyone knows yet.)
Maybe an algorithm that could identify for ex first played note - meaning bass or first string and continue the same with other chords. After that you know where to start. Also there are only few strumming patterns and if you know the measure it should be easier. Just an idea.

> WebGL and WebRTC are JavaScript APIs

I don't think that's a fair description. Yes, WebGL is a JS API but it is basically an entire interface to an OpenGL driver, it exposes a completely new language to the web (GLSL, OpenGL shading language), and it opens up huge new possibilities to the web platform. It has it's own standards group for good reason. It is not just a small incremental JavaScript API addition.

Similarly, WebRTC brings with it codecs and networking capabilities far beyond what was possible before, but I do agree with you there that it is more incremental. But it is also not a mere "JavaScript API"; it is a networking API for the web. The web uses JavaScript, so it has a JavaScript interface. If it were meant to interface with GPU shaders, it would have a GLSL interface too, etc.

> [WebGL and WebRTC are] not alternatives to core web technologies.

Interestingly, one of Microsoft's objections to WebGL was that it competed with core web technologies. The argument was that hardware accelerated rendering was already possible through canvas and CSS. Technically that's true, but of course it misses the point that it gives full programmable GPU control, which canvas and CSS do not.

But Microsoft did have a point, in that if you look at many graphical applications on the web, a lot of them can render to either canvas2D or WebGL. In some sense, the two do compete.

There is also lots of experience with competing APIs. Like Pointer and Touch events, WebRTC and Microsoft's alternative, etc. So that something is an alternative to part of the web stack doesn't mean the standards process can't work for it.

You can't. General sentiment changes over time as people "age out" of society and those with other beliefs enter the majority. See: Gay marriage tolerance, recreational drug tolerance, etc.
The book Lisp in Small Pieces covers a lot of how these can interact, and some of the choices that can be made.

I'd update your resume and look around. Things could get better at your current job, however, if you are able to find something new, you should consider it..especially given your current issue.

You are right to feel annoyed by this. I would. I think anyone who put the time & effort into something would too. Hopefully your boss will figure it out one day.

> The copies are extremely good, and I suspect not many people in the US are going to spend the time to check if a $10 or $20 is fake.

Many places will at least use the marker test on a $20.
Thankfully that case will never happen because you can't be a child if there was an error. :)

Also the check as presumably written would never miss an error, it would just potentially assume valid return values were also errors.
But in C, a 0 in a pointer context is always considered the NULL pointer (even if the physical value of a NULL pointer isn't all zeros).
The problem is that C and POSXIX don't (idiomatically) provide rich enough data types force checking the error condition. The fact that the error is signaled by a random integer (-1) is horrible. In a language with stronger types and richer data structures, one can have a return type that is a disjunction of {failure, parent, child}, so you can never accidentally treat a failure as a PID.

In a functional language this would look like a datatype (essentially a generalized enum), while an OO language you would use different subclasses of a common superclass.

In C you can return a tagged union and check the tag, but nothing forces you to do the check. A user of this API can just go ahead and assume the success branch of the union. Furthermore, this isn't idiomatic POSIX, so it is never done.

[edit: "subclass" -> "superclass"]
What's the point of that? You can hardly use the web with LibreJS active.

Today, users have a choice: accept non-free javascript, or don't use the web.

Which brings us to a goal: we must change the web so that the majority of javascript is Free Software.

Right?
I've been on CoFounders Lab and Founder Dating and there are some quality people on the sites but nothing meaningful ever materialized. Had some Skype chats with a few people but it's always "let's keep our options open and keep in touch," which obviously we all know means nothing will ever come of it. I haven't found alot of people who are serious and committed to building something. It seems like alot of people "exploring" building a startup on the side, or it's something they're considering in the future. I haven't spent much time on Angel List so I'm curious to see how that is.

I'm a Non-Technical co-founder and it's a little annoying when technical founders think and act like people like myself can't bring alot to the table, when we've had previous successful companies before.
I grew up reading stories of lost cities of gold and all that, so when satellite maps became more common in the 2000s I thought for sure we would find tons of lost cities. Unfortunately you can't get much off of even infrared scans of these areas as the buildings are rock and wouldn't have heat signatures any different from their surroundings.

One day I bet we will see more emerge from faster scanning tech.

Hmm, are you really sure that, had you been asked without reading the article, you'd think the average colour to be reddish/yellowish gray due to lighting and ... etc? Really really?

If I'd been asked, I'd perhaps have tried to be clever and said that the top half of the image would be blue as the sky is blue and indoor walls are usually white which won't hurt the blue so much, and that the bottom half would be a browny green due to grass and carpet etc.
The averaging is happening in RGB space, not an HSV-esque space. There's no obvious reason to expect the hue to end up averaged.

For example, the RGB average of red and blue is not orange; it's pink or purple.
This was true back in the mechanical era when a drum was used for control; you physically could not engage multiple directions as green at the same time. I do not believe this is the case now that control is done with software/firmware.

Sorry, i don't want to injure any of the technical writers. They are the only guys keeping big projects from informational collapse. Moreover, they are some kind of project detectives, collecting clues about how this pile of * actually works.

But if you are making something, you have to make some pieces of human-readable information about it and the poor quality is significantly better that no internal documentation at all. That the way developer or manager can help real technical writer.

Also you can express your thoughts in short notes, schema drafts, checklists, documenting your mindflow. It's very usable and nearly impossible to delegate. You can steer at the lines and rectangles or lists, looking for missing points or removing redundant. Not hackworking, just harmonizing the details because it's odd to have time to polish shoes and no time to polish work.
>If you had told me that the energy peak was at X wavelength, I would have guessed that plants absorbed most of that wavelength in order to not be wasteful rather than preferentially reflecting that wavelength.

the plants consume edges of spectrum, so they would bounce the X wavelengths (green in case of our Earth) as it is just an unnecessary heat for them.

Seriously, most people would order this for delivery outside the US (where it's even less likely to be detected if passed at a bank or bureau de change). If they want to use it in the US, order it for delivery elsewhere and tehn smuggle it in.

Ordering for delivery by the USPS would be insanely stupid unless you had a very clearly document legitimate purpose. I'm a bit surprised Krebs didn't order some for himself - with his public standing as a security expert I'm sure his lawyer could work out a way for him to obtain some and then turn it over to law enforcment after assessing it.

Of course, it's quite likely that this is some sort of honey trap designed to attract less astute buyers from the world of organized crime/terrorism.

Another method would be to setup a vehicle or box on the side of the road that emulated an emergency vehicle which instructed the light to change to green in the direction that you wanted it (could also be used to change lights to red if put in the perpendicular direction). http://en.wikipedia.org/wiki/Traffic_signal_preemption

I'm not sure which method is most common. The wikipedia article says that IR, acoustic, visible lights, and GPS can be used to change the lights. It would be fun to experiment with different methods of changing them, but would undoubtedly be illegal.

Apparently it's not illegal federally to use these devices to change lights, it might be legal in some states.

Google would need to do this internally. Good luck convincing the 10,000 developers inside of Google stop using Java. Sure, they aren't all on Android, and there are plenty of people using Go, or Dart, or Python, but moving a company culture that large away from Java doesn't happen overnight.

Obj-C to Swift won't happen overnight at Apple either, but it is much more likely to happen because they've been gradually working towards it for years now with LLVM and such.
That's for performance because I guess the majority of users would probably not notice the difference.

There's a good reason you can't rely on CWD other than root - the directory can be on a different mountpoint and possibly even on a remote mountpoint. If the remote server goes down or the mountpoint is forcefully unmounted, what would your CWD point to then? Root is the only directory guaranteed to always exist, that's why you'd see a chdir('/') as one of the first steps in properly written unix daemons.

That's somewhat true (but you can improve the quality of the median house, just can't improve size).

But that's not true. Buyers decide the median quality of TVs, not sellers. And TVs can be so cheap that everybody only buy the most expensive one, and still it makes no impact on their budget.

Every physical good is exclusive to some degree, but that degree varies wildily.

Forget marketing for a second, if you compare the best Linux Desktop with Windows 8.1, in almost all technical aspects Microsoft Windows 8.1 is vastly superior, it boots faster, applications run smoothly and pretty much everything you plug in works immediately.

but as far as desktop usage is concerned and after using Ubuntu for 2 years (which is a really good OS), Windows is just better (and I can play games while drinking a glass of wine instead of spending 30 minutes tweaking "Wine"), much more refined and in tune with every day use.
