I'm not too impressed with this 'constructor theory' so far. For instance they claim:

>In constructor theory, physical laws are formulated only in terms of which tasks are possible (with arbitrarily high accuracy, reliability, and repeatability), and which are impossible, and why – as opposed to what happens, and what does not happen, given dynamical laws and initial conditions. A task is impossible if there is a law of physics that forbids it. Otherwise, it is possible – which means that a constructor for that task – an object that causes the task to occur and retains the ability to cause it again – can be approximated arbitrarily well in reality.

This seems to be false, as there is no physical law preventing entropy from decreasing but there is a physical law which prevents the existence of a 'constructor' capable of decreasing entropy.

>Moreover, it is a fundamental idea of constructor theory that any transformation that is not forbidden by the laws of physics can be achieved given the requisite knowledge. There is no third possibility: either the laws of physics forbid it, or it is achievable.

Either they are saying something is achievable if and only if there is a constructor for it, which is false (see previous point), or they are claiming something is achievable if and only if the laws of physics don't forbid it, which makes this 'fundamental idea' vacuous.
I actually just implemented some thing very similar to this. You probably want to checkout Dashing [1] which has built in plugins for a lot of things already. It's pretty easy to work with as well.

Free speech usually means you're free to say what you like and I'm free to killfile you if I want. So yes, you have the freedom to control what you hear. I think you agree if that's the definition of "avoiding content that offends them" - when Ann is yelling stuff Bob can put his fingers in his ears, but can't cover Ann's mouth nor Catalina's ears.

I don't really care if it reduces recidivism or not. If you commit a violent crime you deserve to be in jail.
Should I try to keep my startup alive or look for a job?
I've been working in my own startup for a year and a half in my home country, but for many reasons I'll be moving to Toronto in less than a month (August 13th) with a permanent resident visa. I don't have family, friends or connections there and I'm wondering if I should try to keep my startup alive and look for funding or should I look for a job as a web developer (I'm a full stack web developer with a emphasis on AngularJS). What do you guys think? What would you do in my position?
The majority of people are incarcerated for non violent offences, if you give lesser sentences to those people and not give them a criminal record it would solve most of your issues.
I think I would rather take half a dozen dual 10gb ethernet cards and a full 10gb switch.
> I think they should be able to remove them.

I've seen this argument come up a few times, but I don't think it's relevant. Of course reddit has the right to restrict whatever they want, but why should that affect your opinion on what they should restrict? (After all, that's what spez is asking for in his AMA.)
I never noticed the asterisk on the constitution that said "*unless we deem that you are a criminal".
Basic question - but when would you use this over d3.js?
No way! I read about chaos theory butterflies. But now you're saying butterfly wings contain whales? Gnarly, man.

On a more serious note, it's good to see Zhejiang University from China in there. Their library also provides the only scanned copies online of some important ancient Chinese historical sources. Except for the big name unversities in China (Tsinghua, Fudan, etc.), this is a university to watch.

The convention isn't terrible, it's just a convention and takes a bit to get used to. The (x:y:xs) pattern is useful for when you could at best describe x and y as thing1 and thing2 and xs as theRestOfTheThings. Since the extra letters add no real clarity it's not a bad way to keep things concise. Once you get used to the pattern it's better because if you see (x:y:xs) you know that the things themselves are less important than their order out of an array.
I've met a lot of fools who've quoted all the right works, in both Computer Science and Data Science. Computer Science fools usually get fired. Data Science fools seem to get promoted to Yes-man status. It's a lot harder to lie about your code than it is with statistics; As the old adage goes, it right behind Lies and Damned Lies.
Previous episode of violence is a reasonable predictor of future violent behaviour.

What it does do is prevent the violent offenders from committing crimes against the citizenry for the duration of the sentence.
So you argue that reddit should exclude people, rather than content? What if a user is found being racist on another site, should they be banned from reddit?
I think there are definitely big players involved in the coordination of narrative. I think in a world where people live far apart and don't visit the same websites or watch the same shows, it's hard to coordinate action or belief. I think it takes money and organization.

I think Proposition 8 of California is another example; there was a lot of money involved from big players. It's not necessarily a corporation, but I wouldn't say these things are exactly grassroots.
A better or more shocking way to understand how the numbers interplay is, to reframe this like this.
Imagine a vegetable mystical-vegetable, that had 99.9% water and weighed 100 lbs. If I dehydrated it such that it now has 99% water, what would be its weight? Yes, its 10 lbs.
Having an identity and associated public keys that are fully validated is essential in many contexts. Let's say that I'm using a GitHub project, supposedly from a well-known Debian developer. Or let's say that I'm adding the Tor Project repository to Debian, in order to build the latest alpha release. Without well-known and readily validated public keys, how would I know what I was actually getting?

I agree that it's unusual to have multiple independent personas. It's quite common among my cohort, in order to provide deniability. Given the surveillance clusterfuck that's developing, deniability is becoming essential for everyone, even if they don't yet realize it. That will be especially important for young people, who are being profiled virtually from conception.

It does take some technical skill to establish multiple independent personas. One typically uses Linux and/or *BSD, virtualization, VPN services, Tor, Bitcoin, and so on. But getting up to speed only takes a few weeks.
It's not about political correctness. It's just useless to bring up personal responsibility when discussing policy. Personal responsibility comes down to, "don't do that. But some people will not follow that command. What do you do with them? Repeating "don't do that" accomplishes nothing.

"Personally, I feel that if one finds money itself as a goal, then he or she is missing the point of life" And that is exactly the purpose of my question.

I don't see having money as a goal in itself but as a mean to acquire resources/services. But some services/resources are considered necessary/mandatory, I was wondering where we draw the line and what would be the point of having money if all basic needs were satisfied.
Does anyone know if any guard at one of these camps ever committed what would of course be termed terrorism, and shot their colleagues or even a couple of generals.

Can everyone have quietly watched children brained against the side of a truck and not thought "oh, I have a loaded gun!"

Or is complicity a terribly strong bond?
After doing some research into this topic (Extended Random, which was drafted by Eric Rescorla, and how it makes exploiting the native holes in dual elliptical curve easier) I think asking questions about their role and responsibilities within Mozilla are valid.

If this dude is in charge of anything non-crypto related then fine, whatever. But if he is responsible for TLS/SSL or similar, then I have "concerns" given their personal history with the NSA and pushing crypto backdoors.
Nobody needed to convince Californians. The early 90s were the era of the crack wars, where it seemed like every other day you'd read about some kid taking a stray bullet because a drug dealer was trying to take out a rival by spraying his house with gunfire.
Million Dollar Murray: Why homelessness may be easier to solve than manage
I respectfully disagree. I also encourage you to take a look at http://clojure.org/state
I've had the opportunity to sleep in a lot lately, and I've found that I feel physically and mentally the most rejuvenated around the 9 hour mark. Shorter than that and my thinking is on the sluggish side, and longer and I feel tired and unmotivated. Personally, I've found the time that I wake up to also be a factor. Waking up at 7 or 8 in the morning after 9 hours of sleep has me in a better mood than at 10 or 11 with the same amount of sleep.
It looks like crime rates rose- even sharply- in the first part of the decade, then fell (if this source can be believed).

I would disagree with that advice. If you work as a data scientist in a company, you will likely have the logs of something stored in an SQL table (be it pure SQL database or something like hadoop hive) and you will have to answer (and ask) to questions like: "Do people convert more when they come from X or Y?", so you will have to do a couple of queries to get the conversion rates from people coming from X and Y.

This is my experience when I worked as Data Scientist about a year ago. Now, YMMV, especially if you're a freelancer, I guess your clients are more comfortable with giving you raw dumps of data as files instead of giving you access to their database servers.
Wow. It's been a crazy day. http://www.businessinsider.com/new-app-friendstonight-wants-...
It would depend on whether your company has employees and could run alone (ie. with a remote CEO), or if you're alone in your company. It sounds like it's the later.

If that's the case, assuming that there won't be any commercial activity when you're not here to make it happen, then it'll be best to close it down, given that there are in general running taxes and charges, whether your company makes a profit or not.
My understanding is that, because the convict could choose to finish his or her sentence instead, parole is given extremely wide latitude in terms of the conditions that can be set. That does set up other, stupid, situations where convicts who haven't been paroled and hence served their full sentences are given zero supervision after release because you can't force them.

If you wish to be appalled, read this [1] discussing parole boards. For the same rationale as above, they are given incredibly wide latitude with very little review, and often no disclosure, behind their decisions.

It would be nice if we could take the emotion out of what to do. My thought is we need to separate prisoners into two categories: 1. Those who will never be released. 2. Those that will be released one day.

For the first category it does not matter what you do, but for the second we should be putting every effort into making sure they will be released a better person. Punish the first group as much as your morals think is appropriate, but punishing the second is counterproductive.
I mean you're right but it just sucks when you have this massive cash pile that could be used to experiment in interesting ways. Google should figure out a way to monetize that isn't just maximizing clicks and optimizing ad revenue. That's so lame. I understand that advertising (in theory) could really show you stuff that you want in your life and maybe even need, but we aren't even remotely close yet.

It's clear that it's a volume "let's hit users with tons of stuff they just searched for on Amazon", not a surgical strike "let's get users to buy what they need for their own life based on all the stuff they do through our platforms"

In the last three months I've noticed three string queries on Google give me back results with two strings and then one of the strings will have a strikethrough. Sometimes this spans multiple pages. This is terrible
This actually is the power of the algorithm behind webcola, not totally anything greuler does. Still cool though :)
Who did convince them? In 1994, the for-profit prison industry was tiny. CCR cleared just a few million in profits each year: http://www.nytimes.com/1993/05/05/business/corrections-corp-....

In 1994, the industry was tiny, and California voted-in a draconian three strikes law by a 71% margin. In 2012, the industry was booming, with CCA clearing hundreds of millions a year in revenue, and Californians vote to pare back their three law with a similar 69% margin.

To me, your implied conclusion is totally divorced from reality. Rather, the obvious conclusion is that Californians circa 2012 simply came from a less heartless and bloodthirsty generation than Californians circa 1994.
LAX becomes largest U.S. airport to allow Uber, Lyft pickups
There's an Adobe study that shows that Google appears to be cutting impressions (of bad ads?) to boost CTRs and CPC; the same report shows Facebook is handily clobbering Google in CTR / relevance:

* http://www.zdnet.com/article/googles-mobilegeddon-moves-hitt...

Perhaps Google is trying to boost CTR / relevance in order to attract/retain the more valuable advertisers (who would probably otherwise weight Facebook more highly for its better targeting). I really wonder how much of this growth is just Google (and Facebook) extracting more marketing dollars from the biggest spenders.
The topics you mention are maths or applied maths topics. "Data Science" is a bubbly term that roughly means "take that big dump of data and give me some advice on how to make more money", so your list, very sadly, has little relevance with it.
The link to http://www.varlena.com/GeneralBits/96.php from that Wikipedia page was an interesting read.
If GP comes from a more software-dev background, I can understand a general dislike for R. There's lots of things where R can't be beat right now, but for simple data analysis and visualization, there's some damn good python packages like pandas and d3py that GP may find easier to use than dataframes/tables and rCharts in R.
the german version doesn't tell much more.

practically: "the swarovski family were avowed national socialists. swarovski joined the NSDAP before the annex when the party was still illegal."

You'd march to your CO's office, and form a union, and then lobby the politicians for stricter sentencing and a more broad classification of gypsies, possibly. Anything to keep the paycheck.

We have plenty of for profit prisons in the US, and we have had judges go to jail for accepting bribes from these prisons to send more people to jail.

While a jail isn't as evil as a death camp, I think you could definitely argue the conditions in many American jails are horrible, and you are basically will never be able to fit into society afterwards.
>Hate speech is not tolerated here, and most Canadians are in agreement with this.

Please don't speak for the majority of Canadians. I am not in agreement with this and I speculate that many people living in Canada would object to it as well.

Speaking of OCaml, I'm currently working through the Real World OCaml book [1] by Yaron Minsky, Anil Madhavapeddy and Jason Hickey, who are some of the drivers of using OCaml in production settings (Yaron Minsky works for Jane Street, who aside from being a quant firm are also the developers of the popular Core alternative standard library).

I highly recommend it.

Coworking goes micro, extending into the homes of sharing-economy enthusiasts
Uh... Excellent point. Seems the entire speculation is/was unfounded.
Yeah, I think violence is a pretty clear dividing line. I'm not particularly interested in trying to eradicate petty crime by putting hookers, pot dealers, and scam artists away for long periods of time. Even if it worked (and it doesn't) it wouldn't be just.
You assert that Google is "aggressively raising min CPC in a number of categories" and then link to an article that speculates that this might be the case without evidence. They didn't even say "aggressively..."

As for the third link, search ads are not the same thing as mobile display ads from the user's perspective. Remember that in the other case (mobile display ads), Google is probably selling those ads, too.

But publishers have to give it away with the "ad selling engine" embedded right in the content or else they make no money because... no one will honor their copyright and funnel advertisement earnings to the rights-holders.

Look at FM radio. They run ads. The songwriter is entitled to royalties on that income because of our copyright laws and accounting infrastructure. Funny enough, the recording artist is not entitled to royalties because at the time this stuff went in to action it was assumed that radio airplay was a good advertisement for the record, and that's how the artist would be compensated!

The way we're doing thing right now with social media is if the songwriters didn't get any money from radio play. Facebook isn't paying anyone for the content they monetize. Neither is Google. They just index and aggregate and profit and ignore copyright. Imagine FM radio if it was like this. Every song would have to be an advertisement for something else for anyone to make any money.

That's exactly what's happened to our content. They are filled with advertisements and there is no way to remove them! This "web cruft" is a perfect example of this effect! Why can't I just get pure, clean content anywhere? Because then anyone could link to it, and in the process, sell some deodorant on someone else's behalf.

Facebook has realized this and, much like Apple, they've decided to act as a private monopoly of a content industry where they get to set their own royalty rates. They'll take 30%, the "content creator" takes 70%. They'll decide what is worthy of publication and what isn't. We figured out hundreds of years ago that this monopoly should absolutely not be run by a private entity.

Not only would it be much better for individual liberty, but it would be much much easier and apply to ALL content if we could just include royalty payments to rights-holders. That way I just put "content" on the Internet and then if someone happens to be slapping ads on it directly or indirectly, money is making it's way back to the people who made it or paid for it to be made.

I'm not really talking about anything novel here, just looking at some recent history of examples of how copyright has been used in contracts to the mutual benefit of many different parties, including artists, publishers and distributors.
That is a step beyond anything I have said. I am just pointing out that we shouldn't say "Coontown is fine because they keep to themselves."

The fact is that people are attracted to Reddit based on content. You don't need to ban any people if you change the content to attract (and repel) different people.

Reddit is now the most popular site on the Internet for racists to congregate. I think that is a problem for the whole site. Making the site less accommodating to racists would seem to be a good first step in addressing that issue. Reddit doesn't appear willing to do that.

I'm not a sociologist nor a criminologist, but I do drink with them. There are a lot of factors:

1 - there really was (an almost certainly environmental lead-triggered) crime wave that is finally mostly over. Also mix in crack and other drugs.

2 - there was the advent of 24x7 tv news, and when you need something to fill that air time, scary black man randomly killing white people suits perfectly. Even though that is a tiny minority of murders.

3 - people don't understand type 1 and type 2 error: every time a person is set free, some tiny fraction will recidivate (baring incarceration until death.) Mix this in with #2, and you see how sentences increase monotonously.

4 - republicans discover racism motivates voters. See, eg, the Willie Horton commercials [1].
