One of the main events is a free workshop on using Tor and helping patrons install Tor Browser Bundle on their laptops. Seems those radical militant librarians are at it again!"

Human or alien civilisations could practice star hopping. Why travel 16 light years through space when you can just wait until a star with a suitable planet gets close and cover only the last stretch with an artificial spaceship? Take your time for a thoughtful response; it will take another 250,000 to 470,000 year before the close encounter."

I sit in front of a computer pretty much from the moment I wake up to the moment I go back to bed and I've been wearing progressive lenses for about a year now. The correct for both close up and distance.
At first it was a major hassle as I found myself moving my head more and actively trying to find the correct 'sweet spot' for whatever I was looking at.
I really don't have a problem with them now, I thnk it took about a month for me not to notice the additional head movement.
It might be worth going back to your optometrist and check your glasses have been ground correctly - an eye test with your glasses on should suffice. Mistakes are not common but the can occur

OpenBSD, while mostly free, distributes binary-only firmware and often downloads more on first boot.
LibertyBSD is pending review by the Free Software Foundation, which maintains a list of free system distributions. Other distributions on their list include Trisquel, which is based on Ubuntu, and Parabola, which is based on Arch.
To ensure the continued development of LibertyBSD, releases will not be available for download until 3 BTC has been raised. After that, future releases will be available at no cost. 10% of the money raised will be donated to the OpenBSD Foundation.

Recently a developing technology, often called "the block chain", is starting to change this. A block chain computer is a virtual computer, a computer in the cloud, shared across many traditional computers and protected by cryptography and consensus technology. A block-chain computer, in sharp contrast to a web server, is shared across many such traditional computers controlled by dozens to thousands of people. By its very design each computer checks each other's work, and thus a block chain computer reliably and securely executes our instructions up to the security limits of block chain technology, which is known formally as anonymous and probabilistic Byzantine consensus (sometimes also called Nakamoto consensus). Instead of the cashier and ticket-ripper of the movie theater, the block chain consists of thousands of computers that can process digital tickets, money, and many other fiduciary objects in digital form. "I think we see every week now somewhere between one and three entrepreneurs come in with blockchain ideas," says Chris Dixon. "There's definitely some momentum behind it.""
The International Space Station is a vast outpost, its scale inspiring awe even in the astronauts who have constructed it. From the edge of one solar panel to the edge of the opposite one, the station stretches the length of a football field, including the end zones. The station weighs nearly 1 million pounds, and its solar arrays cover more than an acre. It’s as big inside as a six-bedroom house, more than 10 times the size of a space shuttle’s interior. Astronauts regularly volunteer how spacious it feels. It’s so big that during the early years of three-person crews, the astronauts would often go whole workdays without bumping into one another, except at mealtimes.
On the station, the ordinary becomes peculiar. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it’s just as easy to pedal furiously, feet strapped in, without either. You can watch a movie while you pedal by floating a laptop anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale has a tendency to form an invisible cloud around your head. You can end up with what astronauts call a carbon-dioxide headache.
Even by the low estimates, it costs $350,000 an hour to keep the station flying, which makes astronauts’ time an exceptionally expensive resource—and explains their relentless scheduling: Today’s astronauts typically start work by 7:30 in the morning, Greenwich Mean Time, and stop at 7 o’clock in the evening. They are supposed to have the weekends off, but Saturday is devoted to cleaning the station—vital, but no more fun in orbit than housecleaning down here—and some work inevitably sneaks into Sunday.
Life in space is so complicated that a lot of logistics have to be off-loaded to the ground if astronauts are to actually do anything substantive. Just building the schedule for the astronauts in orbit on the U.S. side of the station requires a full-time team of 50 staffers.
Almost anyone you talk with about the value of the Space Station eventually starts talking about Mars. When they do, it’s clear that we don’t yet have a very grown-up space program. The folks we send to space still don’t have any real autonomy, because no one was imagining having to “practice” autonomy when the station was designed and built. On a trip to Mars, the distances are so great that a single voice or email exchange would involve a 30-minute round-trip. That one change, among the thousand others that going to Mars would require, would alter the whole dynamic of life in space. The astronauts would have to handle things themselves.
That could be the real value of the Space Station—to shift NASA’s human exploration program from entirely Earth-controlled to more astronaut-directed, more autonomous. This is not a high priority now; it would be inconvenient, inefficient. But the station’s value could be magnified greatly were NASA to develop a real ethic, and a real plan, for letting the people on the mission assume more responsibility for shaping and controlling it. If we have any greater ambitions for human exploration in space, that’s as important as the technical challenges. Problems of fitness and food supply are solvable. The real question is what autonomy for space travelers would look like—and how Houston can best support it. Autonomy will not only shape the psychology and planning of the mission; it will shape the design of the spacecraft itself.
The idea, known as “Do Not Track,” and modeled on the popular “Do Not Call” rule that protects consumers from unwanted telemarketing calls, is simple. But the details are anything but.
Although many digital advertising companies agreed to the idea in principle, the debate over the definition, scope and application of “Do Not Track” has been raging for several years.
Now, finally, an industry working group is expected to propose detailed rules governing how the privacy switch should work. The group includes experts but is dominated by Internet giants like Adobe, Apple, Facebook, Google and Yahoo. It is poised to recommend a carve-out that would effectively free them from honoring “Do Not Track” requests.
If regulators go along, the rules would allow the largest Internet giants to continue scooping up data about users on their own sites and on other sites that include their plug-ins, such as Facebook’s “Like” button or an embedded YouTube video. This giant loophole would make “Do Not Track” meaningless.
How did we get into this mess? For starters, the Federal Trade Commission doesn’t seem to fully understand the nature of the Internet."

So Google is indeed being optimized..for its own advertising. The message to all but the very biggest vendors is that you must pay to show up. No more getting in the back door by being picked up by an price listing service that gets on Google’s first page, or by matching the search terms well.
But as a user, it looks like Google is cooking its own goose. These crappy results makes me much more inclined to go to Amazon and look at Amazon merchants, and compare price at 3 or 4 Apple vendors I know are reliable with returns in case I get a bum machine. The fact that I’m not getting remotely usable results from Google searches and that means I’ll skip them.
How long will it take for advertisers to realize that they are effectively being scammed by Google, that they are often paying for bad clickthroughs because Google is putting them on search results where they don’t belong but the retailer has written successful clickbait ads so they get bad visits? My impression is that Google Adsense reporting is opaque enough that they might not recognized Google’s culpability (indeed, I can see Google optimizing its algos to keep the bad clickthroughs at the highest level that an advertiser would tolerate).
