There definitely is -- and it may still be too early to say "was" -- a period of social media advertising frenzy among Fortune 500 companies in the last few years. Until fairly recently (with GM's $30M pullout of Facebook advertising the most visible harbinger). Now the honeymoon is just about over, and with it will go the easy money that had basically been throwing itself at Facebook's heels. Facebook in specific, and social advertising in general, will have to find a way to deliver actual results in line with people's sky-high expectations. And they'll have to do it soon. This won't be easy, given that Facebook's ad sales teams have spent the last 3+ years promising the moon to F500 marketing and advertising execs.

But why were all these advertisers so willing to be wooed in the first place?

Because there's a very real (and growing) hole in the advertising landscape. With the erosion of TV advertising as a reliable way to generate mass impressions at scale, advertisers are anxious to find a replacement. TV is still the largest advertising vechicle, by media spend, for most F500 companies (if not all of them?). But premiums on TV are growing each year, even while total ratings are declining, audiences are dispersing (both across networks and onto other platforms), and ads are basically avoidable. While the bloom was on the Facebook rose, it seemed like a hell of a savior to people desperately seeking one.

The fallacy underpinning the leap from TV onto the Facebook bandwagon was the assumption that social media could be bought, and advertised on, in pretty much the same way as TV. In reality, the advertiser needs to be much more savvy and sophisticated about social advertising. He needs to worry about more than just reach, frequency, and CPMs. He'll need to consider the quality of his content, refresh rates for content, geo-targeting and context-targeting, the relevancy algorithms powering his anticipated reach and engagement figures, and the micro-segments to which he serves different ads at different times. Instead, right now he's spent the last few years simply throwing giant checks at Facebook and expecting TV reach, impressions, etc.

I'd consider both parties at fault here: the advertisers for being naive, and Facebook for playing to the deep-pocketed suckers. Picking the low-hanging fruit, in this case, may have set back Facebook's credibility within the advertising community for quite some time. And it also set expectations that Facebook wasn't, and still isn't, prepared to meet. (In fairness, I'm sure Facebook received a great deal of pressure to take the easy ad money in order to make its books look as attractive as possible in anticipation of the IPO).
I don't really get the hubbub about this launch. It's a business innovation

The business innovation is what the hubbub is all about. People aren't excited because of the science, but because this is a watershed moment in the business of space.

All successful technological revolution have to pass through two critical phases, when it becomes possible and when it becomes profitable. This is a big step in phase two.
It's more like 4-20 minutes.
I'm in HW development myself (mostly ARM µC with energy monitoring) and over the past few weeks started wondering whether one of my designs has in fact a fake controller. Pretty clueless to identify it as fake as it would destroy the prototypes and halt development (soldered on PCB, only a few devices).

Underneath your sarcasm, I believe your point is that these models were sustained by paid advertising, thus Pinterest could become profitable by following the same model.

The cost of ads has plummeted in the last few years, and I seriously doubt Pinterest would remain profitable if its primary revenue stream is ads.

I don't know but I've always found it odd to be called a "law", that gives too much scientific credit for something that was clearly derived by simple observation and guesswork and has no underlying science to prove it except that the statement held for some time.
AWS EC2 Ubuntu: No keyring installed error
Right off the top of my head, having given it literally 5 minutes of thought:

If it were implemented as a "convenient" export button, then it would offer a "convenient" way to easily steal all your data. Leave your computer for a second or accidentally forget to log off at the library or apple store? Anyone can come in and download your entire history and pictures and chat logs and who knows what else.

"that's not realistic because it would take too long" or "just ask for password again when you export". OK, but now you've made it even more enticing to steal someone's password since you've created a super easy vector to then gain access to all their info, possibly nicely organized as well. In this sense its kind of nice that its pretty difficult to get old info off of facebook currently.

Secondly, what counts as social network data and what doesn't? Should amazon be forced to provide you with an export of all your purchases so that another web store can offer you as good suggestions and prevent lock-in to amazon? Arguably amazon (or any web store) has already proven to better use this data, and it's as real or more real than facebooks data. How about my Starcraft stats and battle.net chat logs? I know, let's have a long series of litigations to figure this out, in the meanwhile creating a scary and perhaps prohibitively expensive proposition to any new startup that plans to use your prior behavior/data to enhance your future experience.
Churn for enterprise software like GitHub tends to be very low - once it becomes embedded in the workflow of BigCorp its not trivial to change that overnight.

If something genuinely better comes along, the network effects would still be a huge source of inertia given the FUD around switching.

I subscribe to Kurzweil's camp in that I think the halting of Moore's law will pressure a paradigm shift in computing, like the electromechanical, relay-based, vacuum tube, transistor paradigms, the integrated circuit paradigm will cease to be relevant when something like memristors or three-dimensional molecular computing comes into play.
Geez, we seem to have this conversation every week.

If companies aren't being silly, business analysts != data scientist. You still need to be comfortable with various statistical distributions, learning algorithms, graphical models, genetic algos, and possibly some NLP.

Best example I can use: at Knewton I work with two data scientists who can jump from belief propagation or genetic algorithms to infrastructural discussions at the drop of a hat. I don't think business analysts can do that.

yummyfajitas gets it right below: most companies need an analyst, not a DS. That doesn't mean there's no need for a DS.

switching costs are low because of the distributed
nature of Git

Switching costs from Google's search engine are low, because all it takes is to enter the URL of an alternative search engine. And nothing has shaken it, not even when this process is helped by the distribution network, like making Bing the default on Windows.

Lock-in is not measured only in regards to the potential switching costs. Lock-in is also possible by providing the best possible service. Along with real network effects (people recommending your service to other people) then the global lock-in becomes inescapable, even if the theoretical switching costs are low.

And quite the contrary, GitHub locks people in simply because most developers have a GitHub account. People use GitHub these days to put their portfolio on display. And I've worked with a couple of companies that manage their projects on GitHub and it was a pretty painless process to send me an invitation for joining their private repos.

Even Linux is mirrored on GitHub and even Linus Tolvards has a GitHub account. GitHub is not only a really good Git hosting service, but in case you haven't noticed, it's also a vertical social-network built for developers. And their service keeps improving by leaps and bounds, compared to their competitors, which are merely followers. I'm so happy with GitHub that even though I can have as many private projects as I want on Bitbucket, I still pay GitHub for the privilege to have private projects.

Yes, something better can always come along. But just as Google did for search engines, with GitHub around it's pretty hard to build something better. And this to me is the best possible kind of lock-in and the sign of a thriving and growing company: the product being popular, not because it's forcing users, but because it's simply the best.
Too little, too late. Conference calls suck, no matter how you attend them. Presence information is limited to conference invitees? How about the rest of your world? Scheduling, delays, rigid format, single talker - its all awful.

I work at Sococo, and recommend Teamspace as a leap past conference calling.

Ask HN: Best book to learn Objective C
I would like to be able to hack a prototype in a month or so..

I haven't written a line of code in the past 7 years (and then it was mainly VB and C) and I basically need to start from scratch.

I don't like video schools like Treehouse because I find it redundant - I just can't skim through a video, or speed read parts of it.

I am just looking for a book that will cover all the basics and will basically teach me to build my first iOS app from scratch assuming I am an idiot. No more.

Any recommendations?

Exactly. It's not as if everybody left the "good ship facebook" on autopilot. With the amount of cash they have now, they could easily develop / acquire hardware, create another paypal, replicate "google apps for business" or even Android. What about a facebook ISP or even global telecom provider ? Hell, they could even fund a facebook OS.. I'm not saying any of these is a good idea but they really do have some resources (ie $$$) behind them now.

> Here's the fundamental problem. If you can't understand very basic security tools and concepts, you cannot securely operate a computer, much less hope to ever write secure code.

He didn't say he was incapable of understanding it.

> SSH is one of the easiest security tools to use safely that has ever existed. I would say it is second in usability only to HTTPS in browsers

Perhaps that's true, but I suggest testing it would show a massive discrepancy between ease of HTTPS use and SSH use.

In short: I think this is a UX issue, not a PEBCAK one.
Thanks for that, very handy!

The problem here is that the whole security model is upside down. No one else should see or have access to my data.

I am sure that Congress could eventually interfere and set certain rules around the handling of personal data, but more likely, we will soon start seeing alternate technical solutions which puts each user's data in that specific user's hands.

There will come a time when it will not be ethical for companies to store un-encrypted personal data.

As I understand it, aside from the cleaning, it's the same in America. But if a driver pulled over in the middle of rush hour traffic to kick someone off a bus because they put down an empty can of soda, they'd be torn to shreds before they made it back to the driver's seat.

This describes pretty exactly why security questions are hard.

It's not as easy as using tool x and generate key y... its more than using software, if you want security, you have to think about the whole stack, down to the access rights that each part of your hardware has.

There are good and best practices, but with IT Security, using the best practices in one place and just plain forgetting to unlock you PC when you go to the toilet at the office is more than enough...

People are allowed to be afraid when asked security questions.
Neat. I wish I could find a job that used clojure. To overuse a cliche, I know enough to be dangerous but not enough to be deadly. There is a ton of awesome work being done in the language and it would be fun to really learn it via hard problems.
I hope reasoning with terrorists attacking research plants will give some results, but I'm afraid it still wont stop them - they are the same kind of people who blow up infidels or try to get rid of "lesser race". Still, it's a peaceful step and may reduce the amount of such attacks.

What I think is needed here is to actually make security tighter - but it's a dance between putting lots of money into security or losing some experiments. Unfortunately both are what those guerrillas want.
Awesome tool, but I think it shows once more the terrible state of SSH in the Windows world. It's scandalous how MS refuses to make it a first-class citizen on the platform -- it should come pre-installed and pre-configured, or at least with a config wizard, and have simple APIs for third-party apps.

Considering how MS are not really pushing a competitor, I don't understand why they refuse to add such a simple thing. RDP is a completely different tool, and anyway it's not really something you'd expose on the internet, so I don't understand why they can't just integrate OpenSSH -- it's not even GPL!

Of course many governments have the capability.

Warning -- This article posts a longwinded first person account and finally ends with "this scenario is purely hypothetical".

FBs real stock value - PrivCo
Just because FB works for someone, it doesn't mean it'll work for everyone else

To me, the question right now is whether Facebook works for anyone.

I'm genuinely interested, because I've seen media-reported stories of many different kinds and sizes of organisations experimenting with advertising with Facebook, and I honestly can't recall a single one that had a happy ending. I realise that, as they say, the plural of anecdote is not data, but anecdotes can certainly suggest a pattern worth investigating.
