Another possibility might be to use multiple solid state laser transmitter/receiver pairs located close together, kind of like ink-jet printer nozzles. Because they're discreet, you would lose some resolution compared to a continuous scan system, but it might be OK for the purpose of staying in a road.

And, since the vehicle is moving (most of the time) anyway, maybe multiple returns can be integrated something like a synthetic aperture radar system to form a more complete picture.
I'm not quite sure how generating more data about people's locations and putting it in the hands of more people is considered a victory for privacy advocates.
binding to 127.0.0.1 by default would be much better than the actual default of all addresses.
The mind blowing fact is people still pay for long distance calls on landlines and it's not cheap.

Free internet calls have not only existed for years but you can even get free cell service these days with services like ringplus.

So landlines are the new AOL users (and probably a huge intersection at that).
There are two separate issues. One is how prone to security flaws the language itself is. The second is if there are library routines that introduce flaws.

This study is highly dependent on the exact code base analyzed, and especially on the quality of the analysis tools with regard to false positive rate.

I suspect this is largely GIGO but will try to take a deeper look at it at some point.
If the government forces the big American tech companies to adopt weaker encryption technologies, what's to stop terrorists from rolling their own communication app? Or new tech companies from deploying apps from countries where strong encryption is still legal? Would developers need to become familiar with government approved algorithms?

Separate from the debate on whether this is a good idea, I'd love to see a proposal for how a global encryption ban could actually be implemented.
I just did it Orange Book B3/A1 style by visual, result, and trace-based correspondence between code and executable specifications. Plus lots of FSM's. Next project I'd add Frama-C and Astree for code-level verification. Plus, CompCert for compilation with more result & trace-based simulation for correspondence.

Good to see new work, though. I follow Galois' stuff a lot because they're very innovative and practical. Harden et al are also using LLVM simulations for correctness but with ACL2.

TL; DR: For one year, a late-30's academic and his artist spouse document the use of Airbnb, as a tool to facilitate law-abiding, temporary living, in varied New York City neighborhoods.

Airbnb comes out looking responsive, to lack of care from certain hosts. Impressions of neighborhoods vary, as you would expect, sometimes from simply finding contaminated pasta. After gaining a few positive reviews on Airbnb, they successfully negotiate their way into spaces above their price range, while avoiding "red flags", like unmentioned fifth-floor walk-ups.

Great article, lots of tie-ins to various cultural history of the neighborhoods.
I see this from time to time. Some folk seem to down vote what they don't agree with our feel is inaccurate instead of providing counter points.
UK early 1990s or there abouts, using a Sportster 14k4 modem with an Acorn A3000 computer.

I had an account with GreenNet, so I dialled a number in London (4p a min off-peak, I'm in Birmingham) and connected using a RISC-OS telnet client to a very restricted shell account on a Unix box.

From there, I could use a command-line based(?) Gopher client, and I could access email and usenet news. I could also try this new thing called the World Wide Web using a command line Web browser (I think it was links). An FTP client was available as well as Telnet (NASA! Space pictures from USA!).

Then came Demon Internet, Trumpet and a PC after the A3000. The graphical Web on RISC-OS was possible but very slow to render (12MHz ARM chip) although you could save the whole Web page out as a !Draw file.

So I didn't ever pay for an online service on top of the Internet access, I just missed that window. UK would have been something like Prestel (don't think that was Internet based) or Compuserve (Very expensive then). Even with the limited shell account experience, I had that 'Holy Shit' moment.

I haven't had a landline since 2000, so I'm not really up to date with this stuff, but I assumed that what is being referred as a 'land line' today is really a VoIP home phone.
Not only do I not think that is true, I think there's real danger that people conclude that more risk is better. SV is in many ways risk averse. The days when any kid could get a million dollars are over. Almost every success story seems to happen on a background of brand name colleges, companies, incubators or investors. What I think people mean when they talk about risk is really "hype". People move to SV to work in the tech industry because that is THE place to be. You don't have that in London, Berlin or even New York. The pure momentum of the industry simply overshadows any health care, housing, dating problems in the bay area.
I don't understand. What is the purpose of this tool?
So would it be possible to use the pure-Python implementation with PyPy without having to resort to Reflex et al?
Land line user here. Don't get cell service at my house, the WISP we use for internet is usually fine but occasionally unreliable. Also, a couple years ago we lost power for almost a week. So I think there is still a good reason for some people to keep a land line for backup/emergency purposes.
The article didn't imply at all that the factors were directly related. The CDC is tasked with finding health information and trends in the population. If they're missing a large, segment of the population that has very different health trends than the rest of the population, that's a problem and they want to address it, no matter what the reasoning behind the correlation is.

They did talk about controlling for age and income in the article. While the effect was reduced, it was still there. So I'm not entirely sure what your point is, based on the article.
Not sure if you look at military applications then when a group of aircraft will fly in formation only 1 of them would have the radar on in active scan mode and the data is usually going to be shared over the data link.
With phase shift due to movement and the uncertainty of how many cars are there around you modulation might not be enough to prevent cross talk.
I think I still have my old 2400bps modem lying somewhere.

Still, the list left out Videotex systems that were available in Europe, like Prestel in the UK, BTX in Germany, Videotel in Italy and so on.

Those were telco-supplied and allowed to connect to third-party services, although they were comparatively expensive.

Oh, I left out the French Minitel that was officially retired only in 2012.

Exploring Brain’s Role in Openness to Religious or Mystical Experiences
Because I want technology to do what I want while I'm still young enough to enjoy it.

I no longer need more raw compute power, more raw storage capacity, lower storage latency IO. I have a CPU that is more than I need, with more RAM than I need, and said RAM is faster than I need, and the IOPS and round trip latency on my SSDs are better than I need.

What holds it all back for me? The code behind visual UI's keep getting slower. It isn't entirely software, it isn't entirely hardware, but a mixture of both that screws it over for me.

And the ways I want to interact with computers just isn't there yet:

* Microsoft did epic work on the Surface Pen, but I can't just go buy one of those for my Windows PC

* Google did epic work on Google Now, but I'll have to wait for Cortana to catch up before I get that on my PC (without being limited to just accessing it inside of Chrome)

* Stuff like all the non-gaming usage for things like Kinect or stuff like Leap Motion, no one is really doing anything with that for day to day stuff

* I wasn't kidding about Moov, go look at the new product they just came out: possibly the best fitness tracker ever made if you're interested in fitness coach type apps.

And there are other things: the desktop UI still is not based around doing tasks, and browsers suffer from this the most: no browser lets me hibernate collections of tabs (ie, entire windows) to bring up later (either on this computer, or another one; cross-computer window syncing for tracked windows would be absolutely epic).

I feel computers fight me on waaaaay too many things. Computers think they are the destination, but they're really just the vehicle.

The danger of InjectMocks
Currently, money equals political voice, and the rich are the ones running the show because they have an overwhelming amount of money. Money is not rallied in sufficient quantities (millions to billions) by anyone other than the rich. Political privilege means access to cash flow from the people who tell you how to vote if you want re-election support. Ripping this system out by the root and replacing it with public election funding and no ability to receive bribes is precisely what I want.
Security and usability exist in direct opposition to each other. Software that chooses security first is too unusable to gain real adoption by users
I see what you mean, but putting your work value at the company behest is a losing proposition. My work has value even if the company that commissioned it to me is unable to monetize it.

My time has a value which is independent to what the company pays me to actually do. My time would carry the same value even if the company got me to clean bathrooms.

If I had the willingness to start a company and spent my time there, how much money would I make? That's the value of my time, but it carries quite some risk. I am not the best at monetizing software, so I outsource the monetization of my time and associated risks to a third party. They do get a substantial cut of the money, which is fine since I get reduced risk.

If you tie the value of your time to the capability of the company to direct you doing high value tasks you're starting with the losing foot in any negotiation. What if you gave your time to a charity? What if the company needed you to debug some worthless software in the chain as an emergency? Your time has a value even if what you are told to build in your time from your employer has no value - it's the employer loss, not yours.

Apple Watch Myths
I think you're too naive on the nature of people. I do think refugees should be helped, especially refugees that are under the greatest of threats from Islamic governments. I'm thinking about Jews, Christians, gay people, minorities (e.g. Yezidis), children and woman.

But we need very strict screening and currently this is not happening in Europe. A Libanese minister already warned Europe that 2% of immigrants could be ISIS terrorists [0].

The first priority of our governments should be to keep their own people, the taxpayers that make the government possible in the first place, save from harm. Only then are we able to help other people.

Perhaps this is a nice thought exercise, but please don't use this in production. If you need a reliable distributed lock, use something battle-tested like ZooKeeper.
Ah, cool - I will try it then.

My motivation for not requiring root is shared hosting: I have a regular user witch access to an Apache webroot directory. They didn't fully automate Let's Encrypt, but they provide a script which installs certificates for the central webserver. So I have to download and run any ACME client myself to get my certificates.

We don't allow toys here for the fear of lead contamination and here are "2,070 children with blood lead levels above 10 micrograms per deciliter—twice the danger level".

It seems so odd that it takes so long to find these sunken vessels with so much tech at our disposal?? I reckon one good robbery deserves another.
I didn't check every link but I find it interesting that under "improving intelligence", there is no mention of the generations of work previous thinkers have put in to the question about how to be wiser/intelligent, or the question of what that means.

I'm not saying the answer lies in past philosophers, but I think it would be silly to discount previous work done in this area and focus on video games and drugs.
The same could be said about every historical artifact not in display in its native nation. Should we repatriate all artifacts and pieces of art to its original nation?

Recycling isn't the answer, it's part of the problem.
We're all wearing, eating from and washing in, plastic. Plastic or PET comes from crude oil. No health concerns here.

- Plastic in our clothing? Polyester is PET:
http://qz.com/414223/if-your-clothes-arent-already-made-out-...

- " PET, a plastic derived from crude oil that’s used to make soda and ketchup bottles."

- "In the last few decades, production of the material has surged. Between 1980 and 2007, the year polyester definitively overtook cotton as the world’s dominant fiber, the amount of polyester produced annually increased from 5.3 million tonnes (5.8 million tons) to 30.9 million tonnes (34 million tons), according to Tecnon Orbichem. By 2025, that number is projected to nearly triple, to 90.5 million tonnes (99.8 million tons)."

- "Over 50 percent of what is placed into New York City’s recycling ends up in a landfill"

- “Unfortunately the bags (used to transport platics) themselves can’t be recycled—they are too dirty, so they will end up in a landfill.”

- “There is plastic in everything—in your car, in your home, in every part of your life,” says CarbonLite’s CEO, Leon Farahnik. “Globally, 100 billion pounds of PET are used in a year: 70 billion pounds goes to carpet and clothing; 30 billion pounds goes into packaging.” That’s a lot of plastic

- "We don't know if and how many people die from plastic exposure," says Dr. Halden, "but we do know that in the developed world we suffer from a lot of diseases—breast cancer, obesity and early onset puberty—that are less prevalent in developing countries. These are a result of our lifestyle." He adds: "From a public health perspective, we should consider heated plastic an unnecessary source of exposure to harmful elements and eliminate it."

- "(BPA is used) in everything from the lining of metal soup cans to receipt paper. The FDA banned the use of BPA in baby bottles in July 2012, because of growing consumer concerns over its link to developmental delays.

While the recycling numbers at the bottom of plastic items "are not meant to provide health information or risks," Dr. Halden says, they can sometimes provide clues to the chemicals in them. For example, No. 7, says Dr. Halden, means "there is a high likelihood" that Bisphenol A is in it. That reusable water bottle sitting on your desk? "Think of it as one big BPA vessel," he says.
Thanks, I stand corrected. New policy: I should read twice, then say nothing. I'll sound much smarter.
The article says plastics are washed repeatedly, so I'm trying to figure out if putting dirty plastic in the bin is acceptable or not. My city's recycling instructions say to wash plastics before putting them in the bin, and if I can't adequately clean something I've been more inclined to put it in the garbage instead. What's the right answer?
I had a professor who worked in a Dupont lab in New Jersey. He studied crystal structures using x-rays, something too cool for me to comprehend. Anyway he said the lab did work with a mixture of acids they called "Liquid Fire". It would pretty much corrode through any container, metal/plastic/glass. He said there were talks to sell it to the military but it would have been too unsafe to get to the battle field. Note didn't read the article, I think I have read this one before.

Startups already get plenty of free stuff, that's not whats holding them back so it won't do anything.
Curiously, by moving a magnetic field through a non-ferrous metal an eddy current is induced. Then the magnetic field interacts with that current, to produce a force!
Me too. It would be cleaner, unpolluted, less bloody, and the native cultures would probably be blossoming and making interesting stuff by combining their knowledge with outside influences. Too bad most of them were exterminated and dispossessed (the galleon being just one instance of that dispossession), and too bad they continue to be institutionally and structurally marginalised, decimated, and dispossessed.
the government often claims that they will not use gun registration records to seize guns. So far they have not.

Not true in California and I think New York state. Threatened in D.C., and I'm no doubt missing more than a few examples.

Needless to say, the majority of US gun owners are opposed to registration (to the point that such a requirement nationwide would light a slow match to a hot civil war; as it is, the post-Sandy Hook registration laws in Connecticut and New York state have been mostly ignored, in these Bluest of states), especially since there are no significant benefits to such schemes. Plenty of us know our 20th Century history as well and the retail and wholesale democide that registration led to abroad.

>Eddy-current separators use a different approach to magnetic separation: They “repel” nonferrous metals. These powerful magnetic separators “kick-out” the nonferrous metallic products or contamination being conveyed while allowing other materials to continue in the flow. Eddy-current separator systems contain high-speed, powerful rare earth magnetic rotors and are available in a range of configurations. These often include vibratory pan feeders, adjustable splitters, high-speed conveyors, hoods, and even suspended magnets to remove ferrous metals that may also be present.

That's my guess.

Don't use plastic containers at all.
Still, it sucks that the solution involves losing your entire backup history.
My parents still have a landline for largely the same reason. Cell phone only works in certain spots in the house and their DSL requires a land line / isn't reliable enough for VoIP anyway. One second they'll be buzzing along the next will be an hour of 56k-esq speeds.
>Huh. The Time Machine preference pane suggested that I try again later, and I did, with the same result. Since there was an error creating a folder, I guessed that the disk might have some errors, so I ran Disk Utility. Sure enough, there were errors, but Disk Utility couldn’t fix them. Neither could DiskWarrior. Or TechTool Pro. So I was left with no choice but to reformat the disk and start over from scratch. I still don’t know what caused the problem, but neither Time Machine nor any disk utility I tried could fix it—and the hardware itself was, as far as I could tell, just fine.

The last sentence makes absolutely no sense. He said Disk Utility found errors, but couldn't fix it, and neither could DiskWarrior and TechTool Pro. So clearly the hardware itself was NOT "just fine".

>When my backups become suddenly inaccessible for unknown reasons and I’m offered no solution but starting over, that sort of diminishes my faith in the software.

In light of that, what should Time Machine have done? Magically fixed a disk 3 specialized disks couldn't fix and continue?

What would ANY other backup software do?
I've converted several projects over to Caddy[1] and been very happy with it. Caddy is a web server with Let's Encrypt integration built in. Your config can be as simple as:

example.com {
root path/to/root
}

And Let's Encrypt will automatically be used. It's amazingly simple.

I wonder if in the future we'll see things like mod_acme that automate Let's Encrypt into other servers.

Yes, overload is real, you can never eliminate crosstalk only suppress it, and degenerate cases will probably pop up as the tehcnology scales. But coming to a compromise that allows every car to generate a map of the road should easily be possible. Well, "easily" in the technological sense, perhaps not the political sense.

For military applications it's more useful to have one radar at high range/power than to have n radars at low range/power, while it's just the opposite for civilian lidar applications. So I don't see military radar SOP as evidence that this is inherently difficult.
