No it doesn't! You can publish code snippets under the GPL that don't compile at all until incorporated into something else. It's a source code license, not a binary license. If a binary is supplied it's a courtesy not a requirement.
Looks to me like the GPL requires those signing keys to be published if the source cannot be built into a running program without them.
Where, exactly did you look and find that misinformation? The word "compiler", not even compile, occurs once in the entire text of the GPL in the definitions section.
As you mentioned any follow up investigation of the people that had their data stolen would identify any possible soft target and it would have been taken care of within a few weeks, i.e., the person would be moved out of their current position or would have been made to clean up whatever actionable info was on their record or be dismissed. As for the "super secret" remark, I was being sarcastic as the data that was stolen from OPM was of non-classified employees to begin with. I know many people that hold security clearances for their jobs, and they are the squeakiestly clean people I know when it comes to financial and addiction related behavior (alcoholism, gambling and the like). They have to be as they are reviewed every few years to maintain their clearances. They can't even bounce a check without red flags going up all over the place. I think the official review period is every five years, but with all the international turmoil I can guarantee you that DHS is keeping much closer tabs on people with clearances. The days of the 1980s bought out mole are all but over, especially since the Patriot Act.
Well, the HR info would let them buy credit history and other such information so you would know who was having financial difficulties and might be able to be bought.
Medical records might contain information concerning addictions which could be used against them. Either with the addiction itself (giving them drugs or sending them on gambling vacations) or financially. If someone was having, or recently had, a major medical condition such as cancer then they might be having financial problems. There are plenty of ways to coerce someone. The more information that you have the more likely you will find that method.
Anyone with a security clearance (even low level clearances) have to have clean credit histories and have annual drug tests to maintain them. Your examples work for extorting money from individuals in non-classified positions in the government, not compromising national security. You also watch too much TV if you believe otherwise. The data stolen from OPM was for non-classified government employees. I can assure you that any post breach investigation would have found any possible soft targets and the problems would have been taken care of.
You can get herpes from a drinking glass. You can get AIDS from infected blood. The chances are small, but STDs can infect healthy monogamous people. Watch less TV and read more!
The difference is the type of airport. You reference a general aviation example, while the article is talking about a commercial airport. Sundsvall airport handles over a quarter million passengers per year.
ATC and flying a plane are not even remotely similar programming problems. If you think they are, I suggest you do some more research and a lot more thinking. There are too many qualitative issues with air traffic and ground control to simply program around. Here's an example:
You have three flights with the exact same fuel load that need to land. One has a pregnant woman aboard that is going into labor or otherwise has a medical emergency, one has a convict on board being extradited and the other is full of families and others under normal travel conditions. How does the computer get notified of such conditions and how does it make the judgement to land one plane over the other two?
That kind of scenario plays out daily in the skies over the world, but no one says boo about it because it gets handled by a human that can make a value judgement on the fly without a code upgrade! Sorry, as long as there are humans involved anywhere in the model, even as cargo, there will always be conditions that you cannot program around. It's honestly one of the things that bugs me about self-driving cars. It'd be fine if everyone had them, but as long as there are humans behind the wheels of other cars, things like the odd deer that likes to jump in the road, bicyclists and pedestrians I still have some doubt in their current state. There are some talented programmers playing the what-if game and doing a superb job of defining the behavior of autonomous vehicles, but their creations aren't anywhere near what we can do with some simple rules and a brain when it comes to value judgements.
There are too many qualitative judgements needed to control air space and ground traffic at an airport. The cost of developing and deploying all the sensory technology, adequate backups, etc. is almost a deal breaker right there.
Except phones really can be used to trigger bombs. That's one of the things the movies gets right. You just attach another phone to the bomb, and wire it up/program it right to set off the bomb once it receives the right call/text, and BAM! now you have a remote trigger that can work almost anywhere courtesy of the cell phone network.
One problem. Your explanation for what a cell phone bomb trigger looks like in order to attack a criticism that you watch too many movies, sounds just like you got it from a movie or just have absolutely no clue what you're talking about.
Ok, so they've got this super secret info from a government employee database and some medical records, maybe? And? How is this supposed to be something to worry about as far as national security threats go? The info was in an HR database, so the government already knows about that info, and with the possible exception of STDs and maybe psychiatrists what on earth could be used in the medical records to blackmail anyone? On top of that, it's only federal government employees, and only a subset of those. So how does that affect the 100 million or so other non-federal employees that could take the place of anyone in the federal government position that's been compromised? The whole thing is simply FUD for PR purposes and the idiots that wrote the article and approved the summary are the only ones being duped into doing something they shouldn't.
If I'm reading this correctly, our post-doc protagonist has created a deep learning algorithm to automate the process of being shallow? I have no words. ..
Hence, the tag I put on this article #shallowlearning
I know everyone hates 3D but that's because there is no good way of viewing it at present. But that's information you should be keeping for when there is a better technology. As other posters have said, you don't need crazy-high reolutions. Get a decent 3d camera.
Alternatively (this is what I still do) just take two photos a few inches apart. When we take photos we often take more than one anyway so just make a point of taking two. Line up on the first, shoot, then just shuffle a few inches to the side and take another with the camera still pointing at same location. Not so good for people shots though:-)
It's amazing how much more you see in 3d photos. Great for posterity shots. Any 3d tv will give you an idea of how much they reveal... for when a good viewing technology comes along.
First of all, no. You don't know what you're talking about. Second, have you ever tried to take "two photos a few inches apart" of a baby or any other moving object? Yeah, it doesn't work. Third, 3D imagery has a purpose and if you don't have a specific purpose for it, don't bother. It's novelty not worth the expense, which unless you go el-cheapo add-on for a DSLR it's ridiculously expensive for anything of quality; something even near to a simple point-and-shoot quality. Most that have two lenses and two sensors shoot at 10 MP or less. Plus, you can't just look at those images nor print them. People still print pictures for their walls and as gifts.
I'm in my early 40's and I will become a dad in less than a month. Until now I've been quite happy with a Canon Powershot S110 for taking pictures and video, but now I'm thinking in longer terms. If some of you have already thought or done something about this, what did you consider when buying photo/video equipment? What about a plan to store the files you generate? I guess there are important decisions you made about to image quality, file formats, storage type, organizing and labelling software, etc.
I'm also wondering if there are any other technologies (stereoscopic cameras?) that I haven't thought about and may be interesting to look at.
Wow, there are a lot of questions in there that require a lot of detailed and somewhat subjective answers. I've been doing photography since I was seven years old when I got my first real 35mm range finder camera, and have done my own developing and printing, and moved to digital photography very early on in its evolution and still use it today. Let me see if I can give you some quick answers that you can go do more detailed research on yourself.
Cameras with interchangeable lenses are the best buy if this is something you're going to get serious about. If not, stick to what you have or get some simple point-and-shoot with a good sensor and a decent zoom lens (with its optical zoom properties taking priority over digital zoom). I'd recommend something with at least 16 MP or higher so anything can be blown up to an 11"x17" size and not look too grainy. B&H Photo is a good place to get gear and get reviews by photographers and not just the average Joe.
Store the photos on a hard drive, preferably an array of at least RAID 1 so if one drive fails you don't lose everything. Others have pretty much answered this above. Long term you need to look at either redundancy of the array or tape. Yep tape. Costly, but if it's that important tape is still the best medium for long term storage integrity.
ALWAYS shoot at the highest quality setting (image size) for the camera you are using. Again, if quality is important file size is not an issue with today's storage costs.
Format will depend on the camera, but most will be at least JPEG format. Again, ALWAYS use the highest quality setting! Buy a bigger card for the camera. I can shoot all day with a 32 GB card with my 24 megapixel DSLR. I've taken well over 1000 pictures in a day and had no problem storing them util I got back to my laptop.
If the camera supports RAW, USE IT! You can use it in conjunction with JPEG (the RAW+JPEG setting). Why? It's a lot easier to adjust image color, saturation, exposure, etc. after the fact in an image editing app (that also supports RAW, very important) with a RAW format image. Again, this gets important if you want to print the images or ever want to do any pro photography.
Organizing and labeling? I can tell you from experience that if you're not doing photography for money that whole business gets tedious very quickly, and you'll not do it for long nor consistently. I use well labelled file folders and then label the best photos with tags or keywords in the file properties. I use a Mac so that stuff is there, Windows also supports file attributes you can use to add keywords, etc. Yes, I still do this for my very large projects with thousands of raw photos. I'll just mark the ones I've enhanced or otherwise like and just sort based on the tag or keyword and they float to the top. Modern OSes and filesystems are pretty good for this anymore without the need for some sort of specific software like Apple's Photos.
Your last question about novelty photography will get one comment from me: Stay away! Sure 3D images are cool, but the added expense of a camera capable of doing that sort of thing is not worth it once the novelty wears off. It's like the organizing and labeling stuff, really.
Ok, go forth and buy a new camera if you need to. There are several nice point and shoot cameras in the 16 MP
I don't know what photography class you took, but the aperture number of a lens has nothing to do with speed. It has to do with how far the lens iris will open relative to the size of the lens (it's a ratio; e.g., 1.8:1 or 1.4:1) and therefore how much light the lens can get to the sensor; the lower the number the closer to 1:1 you get and the more light you get. Aperture also controls the depth of field for a shot with a larger aperture decreasing depth of field and a smaller one increasing it. This affects what will be in focus in a shot as well as the amount of light and by extension how long of an exposure to use. If you want things farther and closer to you to be in focus you narrow the aperture (higher number) and increase exposure time. If you want only a single thing or group of things to be in focus in a shot you open the aperture and decrease exposure time. The "speed" of a camera comes from its shutter, and unless you're going for a slow motion video camera, pretty much all SLR and mirrorless cameras have similar shutter speeds from bulb (open until you close it) to 1/3200 or 1/4000 of a second. The shutter is part of the camera body, not the lens. Matrix metering is for novices and spot metering is for more advanced photographers that are going for a specific look or effect. Then there's ISO settings that will transpose a lot of the aperture and shutter settings based on what that is set to, as ISO controls the sensitivity of the sensor in modern cameras. It used to be a somewhat fixed aspect of the film being used that could be pushed a few notches one way or another depending on the quality or formulation of the film. If you don't know what you're doing, just use the Program (P) mode on the camera until you take a course. Your local YMCA or other continuing ed organization should have one if you can't find good online resources and experiment on your own.
Uhh, the Bushes ain't from Texas, nor Florida neither, so what's your point? Yje Bushes and Cheney's made ridiculous profit off their war in Iraq while committing war crimes. But please, keep playing your false equivalency games.

Yes, let's move on for a war criminal wanted for crimes against humanity and focus on a mail server that was receiving non-classified email as much as a state state.gov address would have received the same emails as a non-classified email server. Clinton's "crimes" are a tempest in a teapot compared to what Bush & Co. are charged with. I have no love for Hillary and she will NEVER receive a vote from me EVER, but Snowden was a contract sysadmin NOT a security analyst for the CIA! There are more competent and experienced people that have already said that the worst thing that could happen to Clinton is a reprimand, not prosecution, and no, I'm not doing your homework for you, you can go look it up your damn self. Y'all watch too much Fox "News" and the rest of the propaganda channels.
I'm sorry, but if you think that math is not important to coding you're completely ignorant. Not only is math important but the ability to grasp foreign languages is also very important. Computers do math. That's literally all they do! If you don't have a solid grasp of algebra, trigonometry, geometry (proofs et al), statistics, calculus, matrices, vector algebra and beyond you have little use to the coding community other than to do scripting, or as the author points out, rudimentary web site work. FFS, computer science is applied mathematics at its core! Then you get into the linguistics aspects. Yes, I know they're not spoken languages, but programming languages are still functional written languages. They have grammar, syntax and morphology just like any other, so if you're good at picking up foreign languages AND are good at math you can learn to code quite well. If you suck at languages and are good at math you can code, but if you suck at math you're going to suck out loud at coding. The author of that article is a complete idiot, but so are most "journalists" these days. Hell, most of them can't write properly in their own native language let alone code something! Don't believe me, go read some news articles on some major news websites. It's pathetic.
I interviewed at a place that had some of that, like an air-hockey table. I didn't see anyone using it. Maybe it got some use over lunch break, but stuff like that seems like a waste because if you use it, then you're obviously not working, and that isn't going to look good if you use it too much. You could use it after work in your off-hours, but who wants to spend their spare after-work time at work? By then you're ready to get home and eat something.
People didn't use the air hockey table because after the first day someone came out of their office and unplugged the damn thing because it was so loud and annoying no one in the vicinity of it could get anything done over the ridiculous amounts of noise. I know. We had one in our house for about three days before it went back to the store. It's about as useful to a harmonious workplace as a drum kit in a library!
However, consider this. When the internet was just getting going, 320 video was enough, normally downloaded overnight/day to watch later.
Then 320 became 480, moved to 640, 720, and 1080.
Today, we're starting on '2k' and '4k' screens. From interlaced 30hz to progressive 120Hz, 3D, etc...
First of all, 2K is 1080p (1920x1080), and NTSC was 60 Hz interlaced at 29.97 SMPTE drop-frame frames; one odd, one even at 60Hz (our AC power frequency in the U.S.) to get ~30 full frames per second. The 120Hz number you mention is screen refresh rate not content frame rate, either 24 progressive frames per second (most cinematic titles) or 30 progressive frames per second (29.97 SMPTE drop-frame, still) for television.
PV is not the only or most efficient means of generating solar power. I have no control of the crooks raping you on your electricity bills. That's something you'll have to address with your utility company. Also, wind and solar are not the only renewable energy sources. Hydro and tidal are also in the mix with other sources on the drawing board coming along faster than fusion.
