You can't really compare 'car crashes' to 'plane crashes'.

You'd have to take into account that if a plane malfunctions in mid-air a crash is a likely outcome, whereas if a car malfunctions whilst on the road a crash is an unlikely outcome (the likely outcome is you get to call the AA or the local equivalent and you waste some time).

That's what he meant with 'flying is inherently dangerous'. As in: if something goes wrong you find yourself in a spot that is not a natural position for a human being, you're very far above the planet and your plane likely does not have standard equipment to deal with that situation (and neither do you). This as contrasted with a car which will simply coast to a halt by the roadside. That's still not a 100% safe situation but much more safe than being a mile up in a small airplane that decides to stop working for some reason. If it is 'just' an engine issue you'll be making a forced landing and if you're unlucky the terrain may be rough enough to flip the plane, if it is anything besides an engine problem it may simply be 'game over' for anybody on board of the plane.

There is a clear shift when you enter jhana. I think a good analogy would be when you suddenly clearly see the 3d image in an autostereogram, or when you manage to tune a radio and suddenly there is no white noise.
Rails 5 is a bloat too far for my liking as well. ActionCable's dependency on redis is too fat a pill to swallow, especially given that some of the existing ActiveRecord backends have pub/sub capabilities.

The result is that I'm learning Elixir/Phoenix and having the same reaction Dave Thomas describes in his new book, that is, finding anew the joy of programming.

I'm of two minds on this one, but the mind that says 'glad it's being shut down' is winning.

I'm a private pilot / IFR with around 250 hours of pilot-in-command time in single engine planes (I'm guessing that's square in the middle of this company's target pilot demographic). I have a full-time job and fly recreationally. On numerous occasions I've flown friends and relatives e.g. from Palo Alto to the LA area and asked them to split flight costs. Also, while I've never done this personally, it's pretty common for pilots to seek out other pilots on message boards and the like to "split time" on some flight, where cost is split and both pilots can log some flight time.

So on the one hand, if this app were just an enhancement of that same basic pattern ... I'm flying to LA who wants to look down at I-5 traffic from 4500 feet ... then I would think it's great.

The problem is that this service is clearly intended to be more than that. And when you start getting customers who don't understand general aviation and have expectations that my Flyte(?) will run like an airline (or at least air taxi) when it will not be, you have a bad situation.

To give one concrete example, once after promising to take someone on a tour of the golden gate bridge area, dragging her to the airport, doing a pre-flight inspection, and taxiing all the way to the runway, I made a last minute decision to cancel after a new weather report freaked me out a bit. She understood, and we rescheduled. If the person next to me were not a close friend but in fact a "paying customer", perhaps business person with a meeting that afternoon in LA, would I have felt pressured to fly into an unsafe situation? Probably! This is one of several scenarios where the service just seems like a bad idea, from both a pilot and passenger perspective.

I really hate being on the side of 'regulators' in any dispute, but flying is meaningfully different from driving a car. General Aviation already has a reputational problem with sloppy, low-experience pilots putting themselves and their families in danger, and frankly I don't think adding unwitting customers to the mix is going to help the situation at all.

How Much Web Cost Estimation for Your Business? – Infossible
I'm being down-voted. I wonder why? Maybe most people prefer to believe some pleasant lie (that their own country was "good", for example) rather than seeing some unpleasant truth? Or maybe I simply didn't explain myself very well.

For example, in response to the Evian Conference in 1938, Hitler said: "I can only hope and expect that the other world, which has such deep sympathy for these criminals [Jews], will at least be generous enough to convert this sympathy into practical aid. We, on our part, are ready to put all these criminals at the disposal of these countries, for all I care, even on luxury ships."

Back then, didn't the British Empire control like 25% of this planet's land mass? Surely, there must have been some space for Jews to settle? But no, they did not allow that. And the US was a big country back then, too, but they did not allow many Jews to immigrate, either.

Seems to me that Hitler was correct when he basically pointed out that the concern of the US, UK etc. for the Jews was basically just empty talk. Please don't get me wrong here - the nazis were nasty, but the UK, US etc. back then were pretty bad, too. There have been plenty of apologies etc. from the German government over the years, but I wonder if the UK and US governments have ever apologized for their incredibly inconsiderate behavior towards the Jews back then?

Physics used to be "hard science"

I'm not a physicist but pretty sure there's not one kind of physics. Applied physics is still hard science while theoretical physics does not lend itself as well to full scientific method. Both are highly valuable. When Einstein came up with special relativity he had no way to verify it in a lab but that turned out pretty well.

Well I generally agree that titles today are super lame compared to the awesomeness of my own childhood. But it's hard to remove my own subjective nostalgia from the equation, as someone pointed out above.

It may be possible that there is almost too much focus on "quality" now but it's the wrong kind of quality -- lack of errors, linear predictability, control of financial risk in the business of storytelling. Today's cartoons do not take risks, economic, artistic, or political.

I've been watching He-man b/c s1 is free on Prime, and noticed that wow the cartoons are way more interesting than the crap that's on TV today (Thomas-the-Preachy-Tank-Engine; Bob-the-Incompetent-Builder; etc.). There basically is no such thing as Saturday morning cartoons anymore! WTF?! But my son doesn't care. He isn't into He-man, and he does not seem offended by the preachy morality of today's kids' shows, or their slick ultracheap CGI...

I remember reading that putting "click here" in banner adverts produced better click-through rates, as sad as it may sound. I can well believe that the same is true of links, though it ruins the page for screen readers (I went on some training for this once, which advocated link text exactly like your former example, and was told that its common practise for experienced people with visual disabilities to simply listen through the list of links to more quickly navigate to the information they need).
Well, this finally makes sense.

None of the red cone sensitivity plots I've seen previously showed secondary peak, but that's because they were always cut somewhere in the blue region.
Universal healthcare doesn't always work that way though, it's just basically the idea that every citizen is guaranteed some minimum standard of coverage. For example in Japan there's a mandate that all residents are required to have health insurance, but most people have it through their employers. It's not single payer or socialized healthcare. In many countries there's a mix of private and public and a portion of the population is covered by a system like you're talking about, like in the US with Medicare and Medicaid.
Do you see a future in Elixer/Phoenix? And how do you like it?
Because journalists and audiences are incompetent. Journalists only get a press release from Big Corporation which is worded to give the best impression possible.

Meditation isn't magic, it's just stimulus response.

Consider a skill such as hitting a baseball. This is impossible to do consciously, but fortunately it doesn't need to be. You train hitting a ball over and over again, you develop sub-conscious reactions that are triggered by certain things. When you stand a certain way, when you see the pitcher move in a certain way, you react, you spool through a series of actions that your conscious mind only has partial control over, like controlling the reins of a horse.

The same is true for, say, typing. You do not consciously go through a process of thinking of a word, thinking of how it is spelled, then recalling the location of each key, etc. You trigger a mostly unconscious series of reactions, which is why it takes much longer to type out an unfamiliar word, regardless of how long it is.

Meditation works along similar principles. You practice entering a certain mind state, typically relaxation since that is the most important state and often difficult to achieve when desired, and along the way you sprinkle certain ritual behavioral aspects (breathing, words, movements, etc.) Eventually you can shortcut your way there through one of those associative channels.

For myself, I use breathing out and relaxing my shoulders as the cue. If I find myself in need of relaxing or being centered I can just take a moment, breath out, and gain calmness.

You can certainly train yourself to feel sleepier during practice, which is quite common, it doesn't mean you're doing it wrong, but you might think about changing things up a bit if that's not what you want.

However, it's a bit of a general purpose system, it's a matter of training your emotional and mental state the same way you might train your body. You could, in principle, train yourself toward becoming very angry on cue, or any other behavior, with varying difficulty.

I tried using ligatured when Pragmata added them, but the issues made me return to the normal version.

If you use your editor for multiple languages and documentation as well, you may find things like lines in comment blocks made of '%', '#', or '-' to break from the ligatures. Also if your doc markup(-down) uses underlines of '-' or '=' for headings, they are affected.

On Windows, I found some editors where the ligatures were enabled, some where they weren't, and not many where you had any option to toggle either way.

I guess an element of that would be down to the fact that a banner and (or image, in general) doesn't necessarily look clickable without "click here". Text links should always be able to avoid that problem, though.
In theory, maybe. In practice, people will unnecessarily die. People suck at taking risk into account when chosing a service. A service like this will be happy to understate risk and overemphasize the price, and it will force regular airlines and air taxi services to compete with companies that don't have to spend (as much) money on safety. Personally I don't see "minimum safety the market can bear" as a right solution for things that can, and do, kill people.
Yes, that would be the way to do it. And that is exactly why a change like that is just as dangerous as any other.

I did quite a bit of code review during a contract earlier this year. One day one of the programmers shows up with a 100K line changeset, a reformatting and clean up that he'd embarked on of his own accord. Imagine his surprise when I point blank refused the commit. He was extremely upset (understandably, it was a lot of work and well intended) but at the back of my mind were two things: one, we are already under pressure to get things to work and this does not add anything functional. two, if it does add anything functional it will be an error or a bug and there is no way I'm going to catch this manually reviewing all these changes (across 100's of files). So the safe thing to do is to simply not accept the change unless I can free up developer time to break this massive commit into smaller ones that can be reviewed and accepted one-by-one over a longer period of time. And that was a luxury we could not afford.

So too bad, one very inflexible reviewer and one very pissed off programmer. 1000 trivial changes in a single commit isn't going to fly (at least, not with me), unless I review each and every one of those with just as much attention as I would review a much smaller commit. It's that sort of attention to process details that probably makes me 'less than easy' (to put it mildly) to work with but I really feel that if a customer trusts me that I'm going to have to earn that and rubberstamping a change set because it is too large to review is definitely a breach of that trust.

I work on the official Python client for Let's Encrypt, but I support people's decision to use a different client if they prefer.

It's frustrating to see the occasional conspiracy theory suggesting that the Let's Encrypt project somehow wants to backdoor the client in order to compromise people's servers (an idea that occasionally gets brought up on our forums!). But it makes sense that some people want a client that doesn't modify their server configurations. The official client tries to modify server configurations because we believe that many people don't have the expertise or inclination to do it on their own. That goal does make the official client more complex, and there are still plenty of integration bugs to find and fix. If people want a simpler and more hands-off client without the integration features, they should definitely use one, and it's a valuable service that this option is available.
It wasn't clear to me why having toxic sediment sitting behind the dam was that much better than it moving downstream?
Never heard them called that, and so I clicked the link with different expectations ;)
My understanding is this also happened to GitHub and they stayed on 2.3 for years, even maintaining their own fork to handle security issues once official support lapsed. I also understand they eventually realized this wasn't viable long term and made the massive effort to get over the hump.

FWIW, the memory and instrumentation improvements in Ruby 2.x alone are worth the massive effort to upgrade. Good luck!

>Seventy per cent of people born into the bottom quintile of income distribution never make it into the middle class, and fewer than ten per cent get into the top quintile. Forty per cent are still poor as adults.

I'm unconvinced this is a terribly concerning level of mobility. Some people seem to assume an ideal level of mobility would demonstrate no advantage to those born in upper quintiles (i.e., your birth quintile plays no role in your adult quintile), but given what we know about the importance of genetics in passing along favourable human capital characteristics, matching behavior in mating markets, and the importance of social capital -- it seems very reasonable that we would see less than "perfect" mobility.

At the root of this turnaround: the idea that mind-wandering is not a waste of attention but simply a different kind of focus.

Could this be the beginning of the revolt against mindfulness?

I think the article (and probably a lot of modern mindfulness courses/books) conflates mindfulness and concentration meditation. One of the basic principles of mindfulness meditation is equanimity. In terms of 'mental objects' this means being non-judgmental towards thoughts, emotions, etc. Wandering is just one of the many things that occur and when one notices wandering, one can just observe that. If the wandering continues, it continues. If the wandering stops, it stops.

Focus can be a side-effect of mindfulness meditation, but is not the goal.
Einstein was special because he never got lost with reality:

"We can invent as many theories we like, and any one of them can be made to fit the facts. But that theory is always preferred which makes the fewest number of assumptions."

And yet, physics ignores his LAST and FINAL conclusion about HIS theory:

"We may say that according to the general theory of relativity space is endowed with physical qualities; in this sense, therefore, there exists an aether. According to the general theory of relativity space without aether is unthinkable; for in such space there not only would be no propagation of light, but also no possibility of existence for standards of space and time (measuring-rods and clocks), nor therefore any space-time intervals in the physical sense. But this aether may not be thought of as endowed with the quality characteristic of ponderable media, as consisting of parts which may be tracked through time. The idea of motion may not be applied to it."

I think this stems from the fact that other people's experiences are usually not enough to internalise something. You can tell me about it for hours, but unless I have a creative thought in the shower myself, I wont really know it to be true. Once I experience it for myself it'll feel like a genuine discovery even if other people have been doing it for millenia.

Inherent or not, surely what matters is the actual, empirical level of danger? If a plane taxi is more dangerous in practice than a car taxi then I can see an argument for regulating them more stringently, but if the risk is similar then surely the regulations should be too.
