Well first of all Apple has shown no interest in adding jails to osx. Second, there is not yet a proof of concept implementation of Docker using jails (there are significant differences between the implementation of jails and Linux namespacing). Third, you need a filesystem like zfs, but Apple does not support that. Fourth, all Docker code currently being distributed is for Linux/amd64.

Implementing it on FreeBSD would be immensely easier as a first step.

If you're reporting point or interval estimates (rather than the entire posterior) then you are implicitly or explicitly optimising some kind of loss function.

Also, worth a reminder that continuous estimation problems can be viewed as decision problems too, it's not just about discrete decision-making.

I don't think it's great to take the view that, because I'm not making a decision based on this estimate myself, I don't need to worry about which loss function I'm implicitly optimising for when choosing an estimator. Someone else may need to.
While I do agree with you, I think a common "gotcha" is in dealing with port forwards and firewalls.

Eugenics has transmogrified and implanted itself in many aspects of popular culture, so this is actually quite important to those of us who are trying to make the world a better place. The fight against discrimination and hatred is a viable means of increasing everyones intelligence, and not just the lucky few with time on their hands to navel gaze. If you work in the modern social world and don't see eugenics-influenced cultural attitudes in play, you're not looking - or working - hard enough to recognize it. That's why this story is important - even still today. Just because we made it to another century doesn't mean we're not still holding on - rather desperately in some cases - to an antiquated view of our civilization.

Off topic: I'm always a bit mystified as to why people try to use German articles in English texts when they obviously don't know the gender of the word. "Wende" (turn) is female and you thus use "die" as an article. The third possible article is "das" and used for neutral nouns like "Auto". Given it is easy to look up [1], I guess you didn't know there are several?

On topic: I won't state my opinion about the short term cost efficiency of nuclear power, because I don't have the references or raw data at hand to back it up (I wish a lot of others in this thread in the same situation wouldn't either). But IMHO the strongest argument against nuclear power is the uncertainty of long term waste disposal, given that we (currently) can't realistically predict storage conditions on a geological time frame. A month ago there was an article on HN about how we fail to come up with a way to communicate the danger of long term storage to future generations in a reliable way [2].

Even from an economic point of view the danger of a cost explosion of the nuclear waste disposal purely because of political struggles is daunting. In Germany we have a small disposal facility, the Asse, build to test long term storage in salt mines. Because of the usual combination of human error, incompetence and cover ups, waste was dumped there even while it was slowly becoming unstable [3]. Getting it all back out will cost somewhere around 5 billion euros. Guess who's paying for it.

I've started to work with Couchbase 1 month ago. I had to migrate from a relational database to Couchbase, but some basics are missing like unique constraints, indexed columns, etc ...

I've found existing solutions but none fits to my needs, projects are not enough mature, not using promises and missed too many functions, like setters/getters

So I've started some weeks ago my own project, Sofa, an ODM designed to be extensible. I plan to make another project that provides new helpers for Elastic Search.

Any suggestion, opinion and comments are welcomed !
Thanks for the pointer. I see that the bulborama website (the actual seller on Amazon) has lots of obscure bulbs. I love LED lightbulbs, e.g. the Philips 60 W equivalents I've been buying. But for some applications the older incandescents and halogens are better.

> Google often leaves the impression that, as a Google executive once wrote, the cars can “drive anywhere a car can legally drive.” However, that’s true only if intricate preparations have been made beforehand, with the car’s exact route, including driveways, extensively mapped. Data from multiple passes by a special sensor vehicle must later be pored over, meter by meter, by both computers and humans. It’s vastly more effort than what’s needed for Google Maps.
That first followup seems patently insane. "We don't know the value of p̂, so we'll assume it's 5/8". Why would you ever assume like that? The Bayesian approach appears to me exactly like the Frequentist, without the part where they assume convenient values of unknown parameters.

I think when losing some of the progress, I would just give up on the game. Real life would already be negative, so I wouldn't need something negative to happen in the game as well, so the easiest improvement at that point is to stop the game :).

Physicist here.

In terms of predicting the "future state", it depends on what you want to call the "state".

If I know the complete wave function of the system, then knowing the wave function at a future point in time is trivial. Just apply the time evolution operator.

However, knowing the wave function at a given point in time doesn't tell me the position or momentum - it just tells me the probability with which I'll measure a given position or momentum. So knowing the "state" still means that my measurements will have random components.

On a slightly different note, when you talk about knowing the exact position and momentum of every particle, you're not talking about overcoming a physical limitation, but a mathematical one. To put it differently, if I know that the momentum is exactly zero, I do know that the position is. The problem is that the position is NaN. If the position isn't NaN, then I know longer know the momentum isn't precisely defined.

I've been using HabitRPG on a daily basis since April and overall I find it useful. Things I like:

- by far the thing I like the most is the streak counter on the dailies. It's quite rewarding to see you've done your morning light workout 120+ days in a row -- there's just no chance that you are gonna break that chain just so that you nap 10 more minutes!

- low management overhead - I usually spend 1-2 minutes on the website

- character gamification: getting random food and pet drops and critical chance for gold rewards; upgrading items with that gold -- all of these are completely useless :) but even so, these things do give you a tiny mental push to do that extra remaining task. Health and Experience points have similar effects -- I've had days where my character was low health and it was getting towards the end of the day (you lose health if you missed some dailies), which made me consider whether I could quickly achieve one of the remaining tasks

- distinction between daily tasks that are a 'must' and habits that are 'nice to have' but I don't want to do every day.

I don't use the social aspect of it, so I cannot comment on that.
All self-driving technology I am aware of is based on visual input (cameras, lasers, etc.). I'm not sure self-driving cars can get as good as human drivers without any audio input. Noises are an extremely important source of information, especially in critical situations. I guess that a startup focusing on converting audio input into 3D-data (e.g. "truck approaching from behind") could become very valuable.
Is the word "retard" really a necessary or useful addition to this sentence? It is roughly the equivalent of calling someone "nigger" or "faggot" as an insult. When used in this way it is demeaning to the developmentally disabled.

I understand that this is somewhat common usage on the Internet at large, but I believe we'd all like to see Hacker News be better than the Internet at large. And, I'm sure you don't intend harm or insult anyway (other than the "people who move back and fourth between two cities"); but, the harm is there, whether intended or not.

> A updates because "user-clicked-x", and B updates because A updates. But if you're working on B, you ask yourself why the heck did A update in the first place?

Stack traces are a thing. Chrome even has asynchronous stack-traces.

A updates because "user-clicked-x", but it might also update because "user-clicked-y". Or because "user-clicked-z". So now I have 3 things to add to A and to B, because B needs to refresh everytime A does. So if you forget about one of these, then suddenly B is out of sync.

A "solution" to this problem already exists in terms of event listeners. If B listens to any change on A, then A doesn't have to deal with B, but B updates properly and doesn't have to deal with all event types A has to deal with.

Emergency vehicles with sirens.
I've read studies about weed and pain relief. Brain scans still show the 'pain areas' of the brain are active in MS pateints, but patients themselves are generally less bothered by the pain, and it seems similar with opiates. Sometimes the opiates or other painkillers aren't enough to get rid of the pain, but if you aren't nearly as bothered by the pain that the painkiller didn't take care of, suddenly the pain is much more tolerable and you are more able to go on with life. For myself, I notice that sometimes this is the difference between being able to sleep with monthly pain and lying awake. Your reaction is unique: Some people do have bad reactions, and it could be that a different form (hashish, for example) will do the trick for you.

To me, It doesn't matter if the results are actual pain relief either. If it helps make it so the pain is tolerable so that one can function more normally, it really doesn't matter. Perceived improvement is good for the mind.

I personally haven't had any adverse effects aside from a sore jaw and a mild ~36-hour serotonin depression following a trip. In the company I took it -- fellow "psychonauts" who always made a serious effort to control the quality of the environment, the quality of the drug, and the quality of their own mental state -- I've never seen anybody else have serious adverse affects, either. We all benefitted from it to varying degrees.

That said, I don't want to dismiss the potential for adverse effects! LSD is a serious tool. It basically gives you the ability to bypass and/or rewrite elements of your brain's BIOS, which is just as powerful and potentially dangerous as it sounds. I can appreciate the possibility for harm if your environment, mental state, or chemistry go awry. It is dangerous to take LSD in a potentially hostile environment where you don't have adequate support, or if you are prone to certain types of anxiety or confusion. There are plenty of people who should probably never take it; personally, I don't recommend it to anyone who isn't already fairly comfortable with observing and controlling their own mind through introspection and/or meditation.

True, but self driving cars have to be much better drivers than the average human for multiple reasons.

If a human has bad driving habits you can fine him or revoke his driving license without impacting the rest of the drivers. A bug is a self driving software would require to stop all the self driving cars at the same time. Obviously, that would be a problem.

Bad drivers only drive one car at a time and thus they have limited potential impact. Again, a bug in the deployed driving software would impact many more cars, with consequences multiplied by the number of cars. This could have disastrous human consequences, thus more care must be taken.

Finally, human are legally responsible, if something bad happen they can compensate for the damage caused. This is unclear who would be responsible in case of self driving cars.

As a non-American, I was shocked by this bit:

"The net worth of the average black household in the United States is $6,314, compared with $110,500 for the average white household, according to 2011 census data. The gap has worsened in the last decade, and the United States now has a greater wealth gap by race than South Africa did during apartheid. (Whites in America on average own almost 18 times as much as blacks; in South Africa in 1970, the ratio was about 15 times.)"
Without 4, the sequence would be 2, 3, 5. Then the next value would be 9 by fibonacci. But that's bigger than the 5 we get from adding up all the unallocated pieces (2 and 3).

We could use just 2, 3, 4 as a seed, but we can't use the fibonacci formula before the fourth element is added. Try some different seeds for yourself, it's trickier than you'd think.
