That is an excerpt from a book about using psychology for the purposes of persuasion in marketing. It was not a study on the memetic effects of suicide reporting, which aspects of the reporting might contribute to contagion, or a treatise on untreated depression or suicide.

I read that PDF. Twice. It makes some ... great leaps of conclusion and assumption, without much in the way of investigation or data. It concludes for example that young people intentionally fatally drove their cars into trees because they read articles about suicide, but it presents no actual evidence for that case other than a statistical correlation.

As is mentioned frequently on HN, correlation in statistics is tricky: http://tylervigen.com/

I don't think we have enough information at hand to suppress discussion of depression or suicide.
The reasoning behind the ad campaign is that if the ad price multiplied by conversion is below LTV, it's worth it.

This seems to be fine in a market with few other competitors, but in heavily contested categories (e.g., SaaS) shouldn't you be multiplying that by customer churn? Seems a bit presumptions to assume that once a customer signs up, they're going to spend 100% of assumed LTV with you and you only.
I worked this summer as an intern at Conformal Systems where we developed a more sophisticated version of this, essentially a simulator [1] where random transactions between wallets can happen. The main reason for this was to stress-test btcd [2], the full-node bitcoin client that is developed by Conformal. Overall it was a great experience working with Go and bitcoin.

Does Ericsson plan to maintain and update this implementation (my understanding is that WebRTC is still an evolving standard) or is this the kind of "we're abandoning the project and dropping the maintenance burden on the open source community" kind of thing that this kind of announcement usually means? Closed source projects opening their code don't generally end up very successful if they're "dead drops".

As an aside, I notice that the first issue in the github is "implement H265". That seems like a weird priority if you saw what needed to happen to get Mozilla and Google to even consider supporting H264. I think Firefox still doesn't support it and uses VP8.

It's not. If you finish Realschule you can still get an education at a company for a skilled job and afterwards go get your Abitur (to be able to go to college) at an evening school or something.

The early separation isn't the greatest thing (although there have also been people switching, or a friend of mine who changed from Gymnasium to Realschule and after 10th grade when Realschule finished he continued on the Gym and actually got his Abitur), but I actually think it helps because different students can learn at different levels and speeds.

Your criticism stands, though, and more recent attempts to reform the school system have introduced "Gesamtschulen", where all students learn together in one school, but pick different courses at different levels. The results are mixed (not as easy as black+white), but AFAIK not that bad.

Well, it was a state college, I'm actually really good, and we couldn't pick graduate classes in the US, even though I was a senior already, and if you compare standards that basically means graduate. But most likely it just wasn't an engineering school.

Best A/B testing tools for startups
Understanding is "facile" [superficial], but rote learning is the real way....?

Seems reversed. An explanation is she's in Electrical Engineering - my ugrad experience of EE was a emphasis on using tools (formula etc) as opposed to understanding them (that's for Science). Engineers, after all, are paid to get stuff done, not just sit there and grok it. "Fluency" with tools works well for EE.

OTOH, all discplines have "tools" - even pure maths has algebraic manipulation. If you're not fluent, it will slow you down (fortunately, you'll have years of algebraic practice from school).

OAH, most professional mathematicians don't think symbolically (a survey found, IIRC, about 70% visual, 25% kinesthetic, 5% linguistic) - notation not so much a tool of thought as a serial representation (serialization/data format), for recording/communicating. So practice in thinking is what's helpful.

I think fluency with "standard" modes of thought is a double-edged sword. Yes, you become expert with those tools, fast and able. But that very expertise biases your perception and reasoning in terms of them. Thus, it's hard for you to see another way; you'll tend to build on top of them instead. Fortunately, since our tools are pretty good, this approach works well. It's just that you're less likely to see fundamentally new approaches (though to be fair, that's pretty damn unlikely anyway).
With the internet and Video On Demand that's already the case.

> Fourth, looking purely at the "valuation" you get for 6% for $18k is an incredibly short-sighted way to understand the value you are getting out of the program. Mentorship, the network, deep friendships, and core business knowledge are just a few pieces of the value added. But even if you want to add pure money related perks, please review this: http://www.techstars.com/program/perks/. Such free. Much hosting.

No, an exchange of equity for money should be reviewed purely as such.

It's certainly in one party's interest to cloud the judgement by throwing in a bunch of free stuff, but that's also what used car dealers do when they "throw in just for you" a free carwash, a full tank of gas and, heck, why not, some free floor mats to close the deal.
Eventual consistency is much more complicated than that. Patterns for dealing with nontrivial logical operations (i.e. anything that is bigger than a single 'object') are much easier on consistent DBs than eventually consistent ones. On typical RDBMSs you maintain a per-object version number and foreign keys (possibly also a per-object checksum if you're using more relaxed isolation modes). That's generally enough to prevent races, double submits, and other concurrency artifacts over multi-object operations, and it's pretty easy to implement.

The same is not true for eventually consistent systems - checking against a version number can't save you unless all your updates are trivial, single-object ones: some of your updates may succeed while others fail - and there's generally no way to perform an all or nothing operation. In general, there's no one good mechanism for maintaining eventual consistency on nontrivial operations - you have to think (hard) about it on a case by case basis.

The math is feverishly wrong, but that's not the point.

Techstars is a NETWORK. For us (Boulder 2013) it was a window into a world we only saw through occasional blog posts. Techstars is a NETWORK of crazy people who risk everything to start companies. Some of those companies are absolutely amazing, and we have access to their founders, we know them personally. We never even dreamt of such honor.

Before Techstars, we had access to our desks.

For first-time founders, Techstars is truly an opportunity of a lifetime.

For most early stage startups, hosting costs represent extremely low % of expenses. Let's just call this what it is.. cheap way to lock start-ups in your infrastructure.

Same as investing.. give them a year worth of 'funding' and hope they become a massive paying customer.
I use it quite a bit too, and have donated before too, even though you can get it for free, I thought the developer deserved something for his work, as it is truly an amazing app to get for free.
Facebook auto-posting Growth Hack
A friend of mine just built a Facebook auto-posting tool which he's successfully used to add 500 new users on his blogging platform. It automatically posts messages to facebook groups and pages that you've joined on your FB account. I thought some of you might be interested in trying it out.

If you want to give it a shot go to http://mybizziblog.com, register and then head to mybizziblog.com/settings/account to connect your Facebook account. From there go to the admin page (mybizziblog.com/admin) and click the 'Populate Facebook Data' button. It's all pretty self explanatory from there.

If anyone has any luck with it please let me know and feel free to share!

Superb series of articles.
I think there is some truth to this, but personally, I've been to events on both sides of the coin. StartX, for instance, hosted an event where I met several smart people and heard two fantastic presentations. If I were working on a startup, maybe I wouldn't have time to attend, but I'm not at the moment and why not meet and network with smart people with similar interests? That being said, there is a lot of BS you have to circumnavigate.

You can customize style as much as you can. Take a look at Emacs theme gallery: http://pawelbx.github.io/emacs-theme-gallery/

Fyi, people wrote parsers, chat and email clients in Emacs that LT is still dreaming.

You are pretty out of date then. See my C/C++ guide (with demos): http://tuhdo.github.io/c-ide.html. It works fine on navigation projects like Linux kernel, it should work for you likely. With Projectile, I can jump any file instantly, even in Linux kernel with more than 46k files, and I've never seen this in an IDE.

And use GNU Global instead of etags. Finally, keyboard boost productivity many times over the mouse.
So why does it have to be wood? Could you perhaps offer an OPTION to instead use plastic or metal or whatever's in the cheaper frames they sell at Target/Walmart, only custom-sized?

Maybe YOU "can tell a cheap frame from a quality one every time" but I can't. I've never chosen to develop that expertise. Frames all kind of look the same to me, except that a few styles of wooden ones look needlessly gaudy/ornate/expensive. To me, the purpose of the frame is to FRAME - it's not art, just a square one puts AROUND art to protect and separate it. I care what color that square is and what size it is, but what MATERIAL it's made of...not so much.

Of course the chapter isn't itself a study of the effects of suicide reporting—it's an overview of such studies. It's an excerpt from a well-known popular treatment of social psychology, written by a researcher and duly stocked with references [1]. Assuming that Cialdini isn't misrepresenting that literature, I don't see how anyone without a preconceived opinion wouldn't take serious pause at the findings he reports. If you're going to dismiss them you'll need to do a lot better than the usual handwave about correlation.

Let's hear from someone who knows about the latest work on this, or some evidence that those findings are bogus.

1. I mean the book, not the pdf. Obviously I would link to the book if I could; it happens not to be online. The pdf is, and it at least covers the main points (as I recall them—I read the book years ago).

Most Synergy users don't use repos, or Linux for that matter, so this new model works for Synergy (though, it probably wouldn't so well for a Linux-only project). Also, repos tend to have much older versions (at least in Synergy's case).

* How did they change a docile group into an aggressive one? If I understand this correctly, they took a group of, say, 1000 spiders with a ratio of, say, 10-to-1 docile and removed about 890 spiders to create a new 1-to-10 ratio with 110 spiders. But doesn't such a change in group size also change the group itself significantly?

* How was everything tracked after they've been transferred to an environment?

I know some Gazans like elsewhere in the Arab world, but I have never asked them what internet connectivity is like in the Strip. Things are so bad with infrastructure stability, I could not believe they had functioning internet during routine bombardment and military operations, especially enough for startups.

Very interesting article, but I have one pet peeve. The word is halas, it is routinely translated khalas or 5alas (from خلاص). I have studied Arabic now approaching ten years, and I have never seen this mistake before.

What is funny is that, when mocking expats and foreigners trying to integrate culturally and linguistically in Arab cities (I was a target of this of course), this is like always the first word (then maashi, ok, then in shaa allah, God willing) every expat who spends time in the MENA region sprinkles into their speech. Almost always is it used in the incorrect context, with moronically extreme overuse.

The journalist could have easily Googled this: halas tells you nothing on Google, while the first result for me for khalas is Yahoo Answers, where someone asks how to use that word.
He was saying it registers with them as a minor inconvenience.

We tried that a while ago. It turns out, around 90% of Synergy users are very technical (fellow Software Engineers and the like). Often technical people aren't that interested in support because they prefer to figure stuff out for themselves (because we find it fun). Synergy does have a private help desk that Synergy users can contact for troubleshooting, but users that contact the help desk are often less technical (when it comes to Synergy troubleshooting).
