> Is it possible yet to change the visibility of old posts? The absence of small privacy features like this—features that FB does have...

Are you sure you have thought this through? Allowing retro-active changes to visibility (unless it's only in a more restrictive direction) can be a privacy violation for the commenters, who may have commented based on the original visibility list. And allowing visibility changes towards a more restrictive set will confuse the people who could see the post till yesterday, might even have commented on it, and suddenly can't see it anymore.

Privacy decisions are not as simple as they might appear on a cursory glance, and overall I find that G+ takes privacy very seriously. Seen from the above light, the current policy of not allowing visibility changes, but allowing the author to delete the post, makes a lot more sense.
I did it that way too. And while I agree that the best teacher for a person is that person themselves, this is such a basic understanding of math that I think that even the less motivated need to know this.
It looks about as configurable. Zephyros uses coffescript instead of JavaScript, but then again, that's close enough.

The importance of signaling and Kickstarter: It’s not just the money
Yes. Those stupid knobs confused me terribly. I kept trying to move the mouse cursor as if it were my finger, using it to rotate that little notch on the knob. Because, like, it's a knob... right? I mean, I've used knobs before. That's how they work. And this is a knob. I know that, because it looks like one. EVEN THE STUPID BAR GOES ROUND THE KNOB. It's telling you to rotate it. And then you rotate it, and it doesn't work.

Dear people, stop doing this.
Good idea. I'm uploading to Vimeo now.
S-exps are "just" data structures, so that you are reading s-exps when you see other data-structures presented is no surprise.

This is easy to identify: nearly all json is just atoms thought- very few json definitions encode any kind of machine-works or program-code.

So, to put it another way: it amazes you how all Lisp looks like data structures. And hopefully I've helped let you know why you are so amazed here, thanks for reading.
Thanks! I will have to check out your implementation. Has anyone contacted you about using it in their app?
Why is O(n) red and O(n log(n)) yellow? Clearly, O(n log(n)) is slower.

In general, whether a specific complexity is good or bad differs greatly based on what you're doing. I don't think it's a good idea to have the colors be the same everywhere. A particularly bad instance is how every single data structure is O(n), which is red/"bad".
> The average age of first-time entrepreneurs in all industries is 43; in tech industries, the average age is 39.

This obviously doesn't mention how successful those older entrepreneurs go on to be.

I'd like to know if there is a significant difference in the success rates of tech companies started by 18 year olds and 28 year olds. Does it actually make empirical sense to start a company when you're 18, or do those 10 years of working drastically improve your chances such that you should hold off?
'The City' is just a local nickname which has been forever memorialized by the most popular t-shirt in the Bay, the old Golden State Warriors logo. http://c-product.images.dreamsretail.com/46-40/46-40526-Y.jp...

It's just anecdotal, but I don't think many people in California care about San Francisco's housing problems. Southern Californians tend to think SF is "weird" and "too cold." If they pine for a dense urban experience, it's in Manhattan.
Why doesn't your concern apply to public police forces? Oh, it does.
I see a mix. I use Python, but during undergrad one of the required classes taught Perl. Now at a different university, the local bioinformatics group does a "Perl for Biologists" class, and I know at least one lab that still writes new stuff in Perl to stay consistent with legacy code.

Any statistics on what % of successful YC candidates that went to Ivy League schools? I'm going to assume there is a bias that people who go to prestigious Ivy are more likely to apply to prestigious programs like YC so probably a high percentage.
Objectivist theory clearly states that government's one legitimate function is to protect an individual's wealth from usurpers.

I am not making this up.
It in no way detracts from your point, but I believe that asking a 'number sense' problem like the estimation or fraction problem you gave is a different issue than teaching the more algorithmic procedure of solving fraction problems.

One doesn't seem to preclude the other, nor does it seem to mean you won't have success in a science or technology career. I think you'll find a lot of people who know how to solve, say, 'circular motion problems,' but don't really understand what they are doing.
This sounds like a vintage version of Elon Musk's Hyperloop http://en.wikipedia.org/wiki/Hyperloop

I've been tutoring 1 on 1 middle school kids (at the 8th grade level) in underprivileged areas and what I find is that they have little understanding for what fractions are/represent at all. For example, I asked a student what the decimal value of 1/2 was (I had explained what decimal values were beforehand) and she didnt know. I was shocked (maybe its because we're cs people we have a special affinity for 2s). As a further test I gave her a piece of paper and asked fold the paper in half and she knew it instantly. I then asked where on the paper the 1/4 mark was. Again, she didnt know. This came from a further problem of not understanding that (1/2)/2 is 1/4. After playing with the paper folding it in so many ways she started to internalize what these fractions meant.

If minimum wage was $22 an hour the price of dinner for two at Applebee's would increase around 80 cents. $22 an hour is what the wage should be in keeping pace with workers increased productivity.

If the minimum wage was in fact a livable wage young adults could support themselves with an entry level job. I believe unemployment is the highest among males 18 - 22 years old.

Where does the missing 80 cents go?
Maintenance and repairs easily add 10% or more to the total ownership cost, and gasoline over 20%.

$200/month adds up to almost $10k over 4 years.
Patrick, please notice that I replied to pjmlp's comment, which specifically mentioned JavaScript and its prototype-based OO.

While the article may be about Rust and Go, some of the discussion here may naturally go beyond the article's content.
I agree. If I am the principal and the student protests to me and the teacher gives some bizarre-ass interpretation of the problem to me, the teacher will have a problem with me.

I've seen enough of that in high-school physics where the teacher literally doesn't understand what the hell the problem is asking to piss off the Good Humor man.
> You probably haven’t gone to Stanford and MIT

Ahh right, we must be all dumbasses then.

One day I was watching a presentation about programming languages. I thought it was for high schoolers, although the teacher seemed to be exceedingly good, he was talking in a style which assumed approx the same amount of IT knowledge my non-programmer high school 3rd grader little brother has.

It was a Stanford class.
Thanks. It is based on http://nlp.stanford.edu/~wcmac/papers/nli-diss.pdf.

I'd be totally interested in (being spoonfed) research on that, just out of interest.

Threading is good for reading through one time and when there are many topics of interest. Email is something you often return to again and again and topics are organised using subject headers. Email discussion view was introduced by google a very long time ago before almost anyone else did it. It is a bit of a cosmetic trick where it just sorts emails that have the same subject. Threading does not jive with the way Email technology is structured.

Remember when Google tried to build a brand new huge piece of technology meant to revolutionise communication on the web? Nobody adopted it, was called Wave.

"I don't think there are any ethical limits on what you can charge"

I think you can see that some others hold a different viewpoint from you and me. I've heard people say that the ability to review the software is essential for science and that the software must, in all cases, be available for trivial if not no cost, in order to allow that review. (I think this view doesn't have a moral justification.)

"the issue of whether or not to publish is economic"

Absolutely. It's advertising. It's then a question for me to decide how to maximize my profits AND maximize improvements to the field. (Only somewhat apropos, I always loved reading the PNAS blub for each article: "The publication costs of this article were defrayed in part by page charge payment. This article must therefore be hereby marked "advertisement" in accordance with 18 U.S.C. §1734 solely to indicate this fact.")

Getting back to the topic, suppose that a group uses 64-bit USEARCH to do research. You wrote "I'm saying that publishing the source code so that others can run and modify it is the crucial thing." However, that group is unable to provide the source code used to do their analysis. ("Licensee will not allow copies of the Software to be made or used by others", says the 32-bit license.)

If publishing the source code is crucial, then this secondary group, which uses the algorithm, is obligated to publish the software they used, no? Or does that obligation only apply to the primary developer of the algorithm? If the primary developer never publishes the source code, then should all secondary users be prohibited from using it in order to develop new science?

Does that prohibition extend to using Excel? Oracle? Built-in software in sequencing hardware? I don't see an obvious bright-line demarcation.

As for "unrestricted academic license", I disagree with some of the distinction between academic license/commercial license. There are academic labs with a lot more money than I have. The group I was in, in the 1990s, had a NeXT or IRIX box on each student's desk, for example. There are also academic labs which act as a front, of sorts, for a professor's commercial interests. Also, the software I'm working on makes things fast - some 40x more than what people would do on their own. Any group can make the time/money tradeoff, and an academic group may easily have more money than time.

I've decided on a different view. Anyone can get access to the older versions, at no cost and under a BSD license. The newer versions are available to anyone, for a fee, and under the BSD license. I'm not dependent on this product for revenue, so it's a test to see how successful this business model might be.
> You probably haven’t gone to Stanford and MIT.

Queue out X% of startup people in the United States. You know one common quality of great entrepreneurs? They're really good at getting into and paying for elite colleges with sub-10% acceptance rates.

In fact, why doesn't everyone who hasn't gone to Stanford or MIT just smack themselves in the head, abandon their startups, and apply for low-level janitorial positions. Clearly they weren't born intelligent and able to start a startup, otherwise they would have gone to Stanford and MIT where all smart startup people are able to go when they turn 18.

Cult of Mac: Why the iPhone is falling behind
Don't play daft. Mega was operating a business aimed squarely at the US market and built off the intellectual property of American companies. The US interest in seeing that case prosecuted is clear.

If NZ wants to alienate one of the world's largest markets, their largest military ally (and the guarantor of their security, particularly in their shipping lanes) to stick up for a foreign national running a criminal copyright conspiracy on their soil, they're free to do so. Don't get all huffy when they decide not to let that happen.
Doesn't have to be a bullet. In the link (which is a small plane) a door/window seal is suspected as the cause of bringing down the plane. But surely if you can compromise a seal or something and cause a rapid decompression that's going to more than likely kill some passengers at ~12km cruising altitude.

Looked at other cites and there was a study on pilots showing that even a 2s delay from decompression to them fitting masks was significant in reduced control.

My point was only to challenge that the very worst you could do was cause a minor panic without affecting the mechanical flight at all or injuring more than maybe 1 or 2 people.

I didn't check but IIRC that Wikipedia article refers only a bullet passing through the fuselage? In which case the hole is too small to cause even rapid decompression.
Yeah I'd venture to guess if Enron still existed it'd be MORE expensive, not less, to own a model S.

Without hyperbole, [CISPA's] been called the death of the 4th Amendment

He could have written "CISPA has been called the death of the 4th Amendment" and been correct, but here he's decided to go out on a limb and demonstrate that he understands neither CISPA nor the 4th Amendment (or, to be fair, that he doesn't understand what hyperbole is), for no apparent rhetorical benefit.

We are awash in serious 4th Amendment and surveillance/privacy issues. National Security Letters were/are one of them. And if Schneier had the stones to call them out, the "network security" products that enable large-scale surveillance and are sold continuously to corrupt foreign governments would be another one. But if privacy activists want to be taken seriously, they need to stop hyperventilating over fake issues.
Getting Started With OWIN and the Katana Stack
Only if you are comparing Tesla to "not having a car", otherwise gas costs are extremely important.

The problem is, when you tell someone their $30k car actually ends up costing $70k over a few years, they have a knee-jerk reaction (as seen in this thread) - "I don't spend that much" / "Gasoline hardly makes a difference" / "Maintenance costs nearly nothing".

They are basically saying a Model S will affect your monthly budget as much as a $580/month car, I see that as absolutely fair.
The more data they have the less they know. Most people with extreme voiced opinions will do nothing. Thinking doesn't mean doing and doing doesn't mean thinking.

Or those of that upvoted it aren't the ones that came here to complain about it.

There's no reason to assume they are the same parties.

I think this would work great for finding elite soldiers that you need to follow orders without question. However, for a business, demanding they drink on their knees or like dogs is insulting and I rather have somebody stand up and object. Having "A Players" also means they will tell you when you are wrong, not blindly follow orders.
