> I don't have shared my mail credentials with Linkedin, but I assume she has

Unfortunately that's not the case, and it's much darker than this.

Recently I was asked by a friend to open a profile for a non-existing character from her book. I had to create an email address to open a linkedin. A new email address. Never used. After creating profile I emailed this new account from my own email.

Week later my profile shows in character's "people you know", and also the character shows in my stream. Never had option to share contacts on with anyone as I oppose those that.

This situation proved to me that LinkedIn has to have some special deal with yahoo (at least) that they are gathering some extra data about people emailing each other. Otherwise there is no chance in hell that character's profile would guess me.

I'm not saying that yahoo provides a database of all your contacts to LinkedIn, but for example they can provide a streamline of md5 emails and then LinkedIn scrub it and match on their own.

There is something going on here much more advance than simple guessing who you may know.
She and/or her husband probably checked you out on LinkedIn, that's how he shows up in your 'people I know'. It's not really that creepy.

Some time ago I was put on an assignment at another company, and suddenly people from that company started showing up in my 'people you may know' list. And vice versa probably, since I also checked out some of their profiles. This is just what people do these days when they get a job somewhere.
yes, the movie makes a big deal of the fact that "just be more active" is not enough, and I agree with you that she seems to push it too hard.

But she made it in relation to the fact that for some categories (i.e. the US has had a constant increase in obesity for kids ages 2-5 which are not naturally not "sitting all day" types) moving more is not enough, and I felt the underlying points are still valid (school food is crap, adults are unable to understand what "healthy food", that "eat healthy" is not "eat less" etc).
Yeah, that's the author's guess as well.

> And when I say "people" I mean mostly "algorithms," which are faster and more literal than humans.
With about five minutes remaining in the trading day, the company posted a statement on its official website under the headline: “Announcing the Tesla Model W.”

In the following minute, the stock jumped about $1.50 or about 0.75 percent from its level the moment before to as high as $188.50.

Nearly 400,000 shares traded in that time, and it was the heaviest one minute of trading volume in the stock since the opening 60 seconds of trading on Feb 12.

Tesla shares quickly retraced most of that upward move and ended the session at $187.59, down 0.63 percent from Tuesday’s close.
its not, actually. he seems to discourage them on the grounds that a list comprehension would be better. however, that's just alternate syntax for a logically equivalent operation. personally, I use whichever one is more clear to me based on context. I appreciate having the option. Maybe you say that's un-Pythonic because "there should be just one way to do things", but I'm not particularly dogmatic and not persuaded by that.
This is funny. I wrote a NLP program in the past (as a hobby project only) that analyzed articles and press releases to make predictions on stock prices. I didn't even think about adding April 1st (and the day before, to be honest) as an exception in the algorithm. Gives me something to do this weekend.
Wouldn't you still need to use VMs even if IE were available for Linux? Aren't sites supposed to be tested for browsers and platforms? E.g., a site may show an undesired behaviour under Chrome for Windows but not under Chrome for Linux (or vice-versa).

N.B. not a web dev, so please put me straight if I'm wrong.
That's definitely true, it's great to see parts where React doesn't allow people to play with something. It would be a lot more constructive though to build on top of React so we could more easily see the point. Additionally a lot of these problems are well known so before building your own framework, it's worth engaging the React community to see what we are thinking about them.
He did not show up in the list of people that visited my profile. He could have done so anonymously though.
Yeah, I'm not going to lose a wink of sleep over algorithms screwing up and making their owners lost a couple hundred thousand dollars (which isn't even a drop in the bucket). Telsa was not the only publicly traded company that did an April fools joke so I'm not sure why they are being singled out.

You want to hand over all of our trading to computers to make more money? Fine (well not 100% fine but this is not the forum to discuss that) but I'm not going to feel sorry for you when your algorithm bites you in the ass.
> This only handles functions of type a -> a -> a

So, since his toy code was explicitly written to accept the same type for both parameters of the function, you are unable to see how it could be modified to accept a different type signature for the reduce function? It looks to me like a fairly trivial change to get the type of argument `zero`, and use that as one of the parameters to the reduce function.

As for pmahoney's comment, looks like there's a bug. Perhaps he should file a bug report, or pull request.

Apparently my submission of this was a repost -- the author commented on the original post saying:

"Presentation author here. I should have taken this down before it popped up on HN or elsewhere. The video of this presentation is worth watching, because it's tongue-in-cheek through-out. But the slides are not worth reading, otherwise people take it seriously like it's happening here now. Cycle isn't the solution to everything, it's just one guy's ongoing experiment."

Anyways, I found the ideas interesting because I think that its use of Reactive Extensions solves a variety of frontend problems elegantly (and Rx works on backend problems too, making it even more compelling). I made a jsfiddle that explains a bit about Rx to hopefully provide enough context for "why would you use this?" http://jsfiddle.net/nmd88wum/

Anyways, sorry for the respost, and sorry to the author for dragging up something he apparently didn't want being dragged up again. :(
With so many "interface{}"s Go looks more like weakly-typed.

"Apply takes a slice of type []T and a function of type func(T) T"

And after that golang.org docs are saying "We don't feel an urgency for them" about generics"...
Another UPDATE:

I a cousin comment, Retric proves that the integral of 1/log(x)^2 diverges. The point is that log(n)^2 < n for x > 2 (you can prove this by calculus: the only maximum of the function log(x)^2/x is at x=e). So, 1/log(x)^2 > 1/x, and the integral of 1/x diverges.

The most fun way to prove the last statement is that the integral of 1/x from 1 to infinity is greater than 1/2 + 1/3 + 1/4 + 1/5 + ... > 1/2 + 1/4 + 1/4 + 1/8 + ... = 1/2 + 2 * 1/4 + 4 * 1/8 + ... = 1/2 + 1/2 + 1/2 + ....

Yes, this is a good example of why Free Software is very important.
It is creepy in the sense that it reminds me that every action I am taking online is monitored. And in this particular instance, I don't perceive the added value. Basically when it is useful, it is cool, and when it is not, it is creepy.
Not with this specific implementation. However, it would be fairly trivial to substitute one of the elemType arguments with the type of `zero`.

Perhaps a pull request is in order?
I think the bigger issue is that the joke just wasn't that funny.
There's an opinion that his wording is exactly correct, and concentration on avoiding death makes life unworthy by definition. Although that opinion might be incomprehensible for some cultures. I can't think of anything that would explain that opinion clearly enough, but you could read Hagakure anyway.
How long, on average, does it take for another source to declare it an April 1st joke? It seems an easy fix to wait 20 minutes or so. Sure, you lose an edge, but after that you will know everybody is acting stupid but you.

> I don’t currently and haven’t previously used the Imported Contact feature

But perhaps the others did? If 'Steve Jacobs' imported his contacts and you exchanged emails with him, LinkedIn apparently becomes aware of that relationship. In fact:

> Tami has a total of 5 connections, lives in Seattle, no public company or title listed, but we just happened to exchange a few emails a couple days prior regarding some questions I had about software her company sold.

Tami probably used the imported contacts feature here, and that's how LinkedIn would know.
I have to disagree. There are two use cases, reading and changing the source. When Microsoft only allows very limited contributions to the source it either becomes effectively read-only or it will get forked. If it gets forked they will sooner or later face the decision to either compromise on their design decisions in order to maintain compatibility with forks or they start going down the fragmentation road leading to compatibility issues.

Only reading the source is a different story. It should actually be a exceptional use case, for example for debugging, but besides that you should of course usually not worry about implementation details or even take dependencies on them. And Microsoft's documentation of the public surface is pretty good and therefore there is rarely a need to look at the source to understand the functionality.

Finally at least for research purpose it has been possible for a long time to obtain a copy of the source, not sure if this is possible or how hard it would be for non-research purposes.
>They're also using the truecrypt name which was the ONE thing the original developers said they didn't want forks to do.

Well right, they're not a fork so it's not the same kind of problem if they use the name. They're a fansite.
Gyroscope is beautiful to look at - I wish my life was more exciting to take advantage of its visualizations. But will regular folks use something like this?
Agreed. Although I do think that React is "borrowing" concepts from FRP, definitely. Funny how he points the VirtualDOM as if that's THE reason why React is good. It is not. I wrote about why I think you should use React here: http://waltfy.net/2015/04/01/one-reason-to-use-react.html
They're just suggesting people who've looked at your profile.

Your friends looked you up on LinkedIn.
Not having a solution is not the same thing as underestimating the problem.

On the other end of it, you have the question of how far drastic measures can go and still be compatible with a reasonable society.

I was pointing at the change in the slope as evidence that the programs are (perhaps) having an effect, not that everything was all fixed and a great success. I'm perhaps optimistic, because I think countering obesity in children is the most important thing to be doing, and because I think that over time people will tend to learn habits that are useful in the face of food abundance (which is a reasonably recent phenomenon when you look at it in terms of generations).
Have you talked to Patio11? He might know.
I'd recommend "if the date is close to April 1, anything radical needs to be passed in front of a human analyst before it's allowed to affect the calculations" as a solution to these situations.
> Mark Russinovich the CTO of Azure (note Azure, not Windows).

I agree with everything you said, but it's important to note here that Russinovich is a well-known Windows reverse engineer, the founder of SysInternals, and the author of the Windows Internals books (these are akin to the Design & Implementation of BSD books, but for Windows).

He's something of a deity amongst Windows kernel hackers. I also believe he pops on HN now and again.
Wait a second, since when did OSI (or any group in particular, for that matter) become the ultimate arbiter on what "open source" means?

I'm not saying this to be argumentative - I don't like the idea of something like that in the hands of a bureaucracy.
> You don't seriously think that was anything but a consequence of your specific setup, right? Dual booting with Windows 8.1 and Linux is most certainly possible.

Yet is is. It is a consequence of the fact that windows overwrites things like the master boot record that live outside of it's partition on a hard drive without asking the user first.

Yes dual booting is possible. But as always installing windows second makes everything else unbootable (until fixed).
> I used to do development for a DOD project. At the outset of the project, it's often not clear what you're trying to do will even work. It might not even be clear what you should be trying to do.

Doesn't this just sound like the contractor promising things it can't deliver? This seems like one of the major endemic problems, especially with ridiculously advanced projects like this.

R&D is R&D. Contracts are contracts. Research, by nature, fails often. Contracts, by nature, are expected to succeed. You can't (or rather shouldn't) sign a contract for something that you don't know you can do, let alone whether you can do it within the time / money limits. To me, that seems borderline fraudulent, and is a form of lock-in. The clients don't know they're getting screwed, but when they finally do know, it's too expensive for them to switch contractors and they're stuck with you.

Obviously it's partially an incentives issue - it's economically rational for companies to do that. It's also probably a rational career move for officers to pitch a super-mega-awesome device that doesn't exist yet but sounds awesome. So that needs to change.

What happened to trying before buying? I have a sense that this used to be the case pre-WW2 but I don't really have any proof to back that up.
Good to see this cool project get some attention.

Looks are deceiving. `interface{}` != `void *`. The value inside the `interface{}` box is still strongly typed, it's just boxed to make function interfaces simpler (given Go's lack of generics).
> You can use a mapping transducer to express map, but it's actually going to have slightly worse performance than regular map.

That's a strawman argument- Neither OP nor my comment made any mention of "map". This is a discussion about reduction and filtering. Yes, using transducers in a way that is silly like you suggest will produce disappointing results.

> Also something to keep in mind is that kids today are used to input lag. Both PS4 and Xbox One uses wireless controllers.

The input "lag" with wireless controllers is not in any way comparable to the lag introduced by streaming your game over the internet. For example, tests have shown that my current wireless mouse — the Logitech G602 — has no more latency than a wired mouse. (The range is crap, but that's another issue.) Nor have I had any latency issues using my Logitech F710 gamepad, even with high octane games like Super Meat Boy.
I'm not sure that time and bodies necessarily produce good abstractions.
Zaroth has really good practical advice, but regardless of how much you have in the bank, I'd caution against doing anything too creative with the money. Investors aren't looking to make half a point on their money and they aren't giving you money to invest anywhere else. It's a good idea to make sure your money is secure and you aren't being negligent in your cash management practices, but I don't suspect your board will be impressed if you come up with a fancy scheme to make investment returns on the money they gave you to run your business.

I'm sure it could, but only at the expense of ballooning to an even more disproportionate length.

What happens if you quote a large figure and they take you up on it, despite the fact that you never intended to honor the offer? Congratulations, now you're a jerk.

When I wrote it, I had originally written "optimal" as "efficient", but "optimal" has multiple meanings here.

The point is, if you would arrive at a requirement of $x to implement the thing in an exercise where you decide to entertain all requests as a request for a legitimate bid, then don't quote an arbitrary figure of $y. Quoting $x works out the best for everyone in all possible cases, where the approach to quote an arbitrary figure falls down in more than one place.

I had an interesting experience last year when I was working in a co-working space. I noticed that LinkedIn started suggesting to me the other people who were working in the same space. I had no verbal or virtual contact with these people, other than basic office small talk, but I never knew their name and they never knew mine. I mentioned it to them, and they all claimed they hadn't looked me up on LinkedIn, and that that was very weird. My assumption was that LinkedIn knew we were sharing the same internet connection and so they linked us together.
Many of the successful algorithmic trading platforms rely on super quick transactions, 20 minutes is a lifetime for many companies, especially when they invest heavily to shave mere microseconds from transaction processing times.
This is Angular 1.x course because Angular 2 is nowhere near stability. It also won't be for another few years - that's how long it takes to build an ecosystem of packages around anything.
I'd say apart from people wanting to contribute to Angular 2, or maintaining packages that may need to be ported to Angular 2, nobody should learn it right now.

The other two arguments are actually not in favor of the point you are trying to make. For beginner wanting to just have something awesome working, Angular is a perfect way of getting hooked. Sure, for senior JS developers learning Angular is perhaps not the best move - it is very isolated, built on assumptions suited mostly for small websites and, as you said it, "magic". Those are the reasons why Angular 2 is so different.
Same here. At first I almost concluded it was some, uhm, "manifesto", which wouldn't need any arguments and all the folks except me know what it is about already.
That reads like an April Fool's joke, but I followed the link to Github, and this has been acknowledged (and fixed) as a "security-high vulnerability":

Isn't there something in between weekend-project demo games that you master in 5 minutes and AAA games with million dollar budgets? Also I disagree with this:

> Thing with HTML5 is, it's not a user-demanded tech. It's a developer tech for people who want '1 codebase, all platforms that have a browser', i.e. TVs, phones, tablets, PCs, consoles. No user is actually interested in playing HTML5 games, it has no known benefit to them, so it's never advertised as such and so there's no real stores built around it.

I'm a user and I want it. The ability to play a game on any computer without installing Steam and then installing the game and then setting up a controller and etc. etc. is a huge win for users.

I understand that browsers aren't ready for AAA FPS games (or at least the makers aren't ready to put the effort into html5 export) and I'm fine with that, but I think there's something in between, like a Super Meat Boy that is still a full-fledged game and can easily work in browsers.

I'm just surprised that there are virtually none of these out there.
