That doesn't mean it's a real business at all. It could be a sign of over hype, over valuation, and just foolishness. I mean, the proof is in the pudding here. I guess there was very little risk management done here. Joel Spolsky wrote about not making this mistake awhile back, though I have "google block" and can't seeM

What would you use instead?

LoC isn't a perfect metric but it is very easy to relate to. Given some extra context like the type of application, the size of the company or the age of the codebase one can mentally account for some of the weaknesses of using LoC as a metric.

If this were a study using LoC as a sole metric with no other context I'd agree with you but LoC seems perfectly adequate in this case.

- Victims of murder, kidnapping, torture could all claim similar boycotts for those terms.

- PETA might say just hearing the word "slaughter" brings them to tears.

- religious groups are offended by all kinds of things. (eg. homosexuality)

No one can claim a monopoly on being offended. Part of living in our modern multicultural society is that you grow a shell towards these things. Your problem with these words should not impede the freedom of those around you.

Rape in and of itself is a terrible crime. Yet the word is just that, a word, and your personal offence is not unique. I get offended too, everyone does. Just to different things.

Can you imagine the bland and chaste world we might live in if every complaint for personal offense on the radio, tv or internet was taken into account.
Ah No - it should be quite easy to achieve. There are two types of API calls for the Twitter API (IP based and OAuth). Oauth provides you 350 requests per hour. It's quite easy and off the shelf packages are available. So, in summary you could use 10 Twitter accounts and make OAuth requests from each of these accounts by polling.

1 hour = 3600 seconds
Assuming you use 3500 seconds to make API calls (the rest 100 seconds is used for performing disk operations) 10 accounts should be more than sufficient.

:-)
Well a table driven rules engine for tax is probably a whole programming language with optimizer at a guess... and then it has to generate custom UIs based on the local tax rules. I can imagine this being bloated.
I hope that Rails has the weight to push these kind of changes into Rack.

I think that Rack is one of the best things that happened to the Ruby web-application community, and I'm a little sad that Rails is getting a "vendor specific" implementation of what should be a wide reaching feature. As you said at @scotruby though, Rails is in a unique position to direct the development on both sides, front and back end of development. (I believe in Scotland you were referring specifically to pushing backend queue implementors to meet the new Rails queueing API.)

I'm looking forward to seeing people building upon this for common use-cases such as streaming reports, CSV exports etc to clients, as well as the more `fun` stuff about live browser reloading (which guard-reload implements very nicely, actually, using a different technique)

And, I think it's fair to say that using a queue, and having a queue consumer (again, I think you demo'ed that in Scotland) isn't such a bad solution, at least as a more experienced developer I appreciate the moving parts, and it doesn't distract me too much from solving the problem at hand, and - most importantly it works.

That all said, I think this is a valuable change, and I thank you for your time in making it work, and coming up with an interesting test-case.

For what it's worth, my last word would be about a post on HN a few days ago, about streaming JPEGs, multi-frame streams often (apparently.) used for IP camera livestreams, that's quite an interesting case which could lead to this controller technique being used to do live image previews without page reloads in Rails with AJAX image upload.

A product developed while Steve was away from Apple, a project he was forced away from, a success (if not up to iPhone levels) and a probable future success (for Intel!). What's your point?

Seriously, the AppleTV is only a 'failure' by the standards of the iPhone and iPad -- most companies would love to have a product that sells nearly 3 million units per year! The margins may be lower than the iPad's, but my understanding is that it does still make a decent profit.

Thunderbolt is an Intel technology and an incredibly useful one. The available products are already starting to look impressive in functionality and prices will come down before too long; Apple themselves use it to provide gigabit ethernet on devices that are about the same thickness as an RJ45 connector, and they sell those for just $29.
I'm know if I'm wrong about definitions or the title is misleading but this is talking about the definition "modern humans" in the sense I was expecting: neolithic culture (agriculture, pottery, permanent settlements, megalithic relics, large groups).

Rather this is evidence for what I've heard called "behaviorally modern humans." They know about behavioral modernity in other places (including Africa) during this period. http://en.wikipedia.org/wiki/Behavioral_modernity

Still fascinating, but don't expect 40 thousand year old pyramids.

I come down on the side that it shouldn't be so difficult for Facebook to at least spot some of the 4 bots per human.

However, even if you assume it is a hard problem - thats more reason that they should have listened (and responded!!) when a company identified this problem with some hard data to back it up.

As a German from the hard industry Ruhr Area which was heavily bombed during World War 2 I can assure you their database is useless. There are 1 or 2 hidden bombs found in the ground EVERY month which apparently come out of nowhere because they are neither on the pictures of air reconnaissance after the bombings nor in their protocols for being sent at all. Yesterday they found a 1.000 pound bomb in Wilhelmsburg and 2.000 people had to leave their homes temporarily for its deactivation. A dredge had found it.

I do agree that it is a bit off (read: probably illegal) that they allow users to change the password and then store the user's password in plaintext. The system would be considerably better if users could only use a system-generated password.
Mashape doesn't standardise anything - it "just" provides API billing and management tools.

Is there any particular advantage to using something like this for static code samples instead of just pre-rendering the HTML and CSS?

I usually just export my code from Emacs via M-x htmlfontify-buffer which dumps a bunch of CSS and HTML. This also allows me to take advantage of my different Emacs themes. It also outputs CSS with good class names like "string" or "keyword". If you add your own custom faces, it just uses the name you gave them. This means the coloring is exactly as customizable as it is in Emacs. It is also very easy to theme with CSS to match your site if you don't like any of the Emacs color themes.
That's more complicated. Often our beliefs aren't even coherent. (The canonical example is the "I have a Dragon in my garage", where any experiment you can come up with will fail to show the presence of my Dragon, and I know it, even though I still "believe" there is a Dragon.)

So it is possible to lie to yourself. Rationalization, wishful thinking, motivated cognition… As we are on average terrible liars, it's often easier to first convince ourselves of the lie, then repeat it with a straight face.

You're right; in this case it probably is adequate. I'm by no means an expert programmer (alas, I come from the business development/marketing side of things), and I used to measure things in LoC as if it were a be-all end-all metric. Then I started programming and realized how ridiculous that is.

It's probably the best metric to use, I just wish there were something better.
Ask HN: How unethical is it to develop insecure applications?
I've never once worked on a web project where the client was adequately concerned about security and willing to pay for it. Almost invariably it's an afterthought. In some cases a client flat out refuses to pay to make an application secure, even in the case of clear evidence of dangerous insecurities.

So should I refuse to work for people who don't care about security? If I did so, I'd quickly be out of this business.
"Unlike the Nobel in physics, the Fundamental Physics Prize can be awarded to scientists whose ideas have not yet been verified by experiments, which often occurs decades later. "

About half those awards went to string theorists, and they'll likely be waiting a lot longer than a few decades for experimental verification. Try centuries or never.

While I'm in favor of this kind of prize, I think this crop of winners shows a clear bias towards things that may not ever pan out while ignoring much more important contributions to science that are actually verifiable. Untestable theories are all well and dandy in that they might one day lead to something testable, but there's not much point in handing out awards for such stuff until it does!

What are the implications of all this in other areas, fields and future of humanity in general?
Yes but grep is not allowed for this task, it is not socially acceptable. So how would you do it in an Apple way (cool, stylish, hipsterish) without freaking people out?
True. And because of this I think at this stage it's impossible to say which one will become huge. They're all lacking two extremely core components: credibility and any sort of structured curriculum.

Credibility:
What employer understands the value of Udemy or Coursera courses? Essentially none. And understandably so.

Structured curriculum:
No high school student today will spend on their own time, instead of going to university, 1-4 intense years of Udemy or Coursera courses. A very large majority of high school students haven't the slightest clue what they want to spend their life doing. Without any clue, there is no way they will have sufficient drive on their own to lead their own education efforts.

I haven't seen anything from either of these websites that even come remotely close to solving these issues.

This is how you do it:

(a) Estabish what you spend on ads per visitor.

(b) Establish what you earn per visitor coming from ads.

(c) Only if (a) minus (b) is positive, continue running the ads.

However, Facebook should have a look at this issue. It is the reasong why Google's AdWords is so successful, and most other self-service ad programs fail. AdWords is very good in filtering everything that does not represent a value for the costumer (the advertising web site).
It won't become cheaper and safer to get humans into space at any reasonable pace if we keep focusing all the R&D on how to get robots out there in a cost effective way.

Have you seen the type of landing solutions they're coming up with for the robots? They're all going in a direction driven by the realization that since they're not humans, they can afford to take far higher risks and subject them to stress that would otherwise be completely intolerable, so they're explicitly not trying to address the complexities of bringing humans into space.

I'm happy for work on robot probes to go on, but that's no reason to not also invest more resources in the groundwork for cheaper human space flight.

It's not common on other networks or on Facebook. This is likely an isolated incident. I've been advertising on Facebook for months and >80% of the clicks show up in my own stats, not <20%. If advertisers were regularly being billed for 5x the ad clicks they actually received, this wouldn't just be coming out now.
Right, but CodeMirror can be used as a simply syntax highlighter as well.
Having half of the first winners from the same field, considering that they will also constitute the committee that will choose the next winners, brings a pretty big risk to keep these awards biased.

But even theories that are not proved correct can advance human knowledge, by giving inspiration to other theories - even in different fields. So, in my opinion, an award for that kind of work could be useful in advancing science even if it doesn't award proven theories.

UBS sues Nasdaq over $357 million IPO loss
This is a mostly solved problem though. Or at least there are people and products out there that do this specifically for you, not with a focus on bots alone as that is a bit of a edge case but for mobile devices.

DeviceAtlas and WURFL are both products that I have used that attempt to have complete coverage of all UA strings in use in the wild even, the ones that attempt to spoof legitimate UA strings.

While their focus is on device detection and the properties of these devices for mobile content adaptation, knowing which connections are from bots is just as important if you are going to alter what content you serve up based on UA.

These product actively seek out new UAs and add them to their rule sets in a way that I can only assume will be more accurate over time than a home grown solution.

FWIW I know that FB use at least one of these products for their device detection, so if you want to match what FB thinks (knows!?) this is where you would start.
CanCan nested permissions possible?
[Interview]Gilles Babinet: Entrepreneur, Investor, Digital Champion of France
I think the opposite is true: more abstract code is easier to maintain. Why? Because the abstractions constrain what you can do in well-defined ways. Code for your particular domain tends to be somewhat undefined. What sorts of behaviors should you allow? What sorts shouldn't you allow? The answers are going to differ with each domain.

On the other hand, these questions are very well defined for mathematical concepts. If all you know is that you're operating on a functor or on a monad, the possible behavior you can rely on is based on concrete mathematical laws. As a simple example, take lists. If you just treat lists as lists, there are all sorts of possible problems you can run into: off-by-one errors, not accounting for empty lists and so on. If you write code across all functors, on the other hand, you cannot make any of those errors.

Essentially, abstraction like this lets you concentrate all the possible errors in a very small portion of your code. You can write the abstract code assuming that the functor laws or the monad laws or whatever applicable laws hold. Moreover, since the code is polymorphic, the type system guarantees that you cannot do anything not provided by the abstraction you chose. Code that does something beyond the abstraction is simply not well-formed--it relies on properties of the type you simply cannot access.

This means that all your code will be valid given that the type behaves like a proper functor or monad or whatever. Now the only code you have to test for your particular domain is the functor or monad instance. Once you prove that your monad instance follows the monad laws--which really isn't very difficult in most cases--you know that all your abstract code also works for this particular domain. So now the only place you can have an error in is the code making your type an instance of some type class. This should be much easier to maintain than having a bunch of ad-hoc code for each particular domain!

In short: more abstract code is easier to maintain because it restricts the programs you can write. If you rely on as little knowledge about your particular domain as possible, you will have far fewer places to make a mistake. Mathematical abstractions are particularly good because they tend to be far better defined and understood than purely programming abstractions. Something like Iterable doesn't have the sort of mathematical laws that classes like Functor and Monad do.
Thx for the tip. We're on it.

If the company isn't complying with Data Protection laws and sensible security measures with access then I would feel it was my duty as a professional to contest their decisions. I wouldn't become a whistleblower but I would escalate the problem until some one listened. Security breaches hurt the reputation of a business. There will always be some one who will care about this. Maybe not always in the tech teams but at least in one of the business function teams.
I don't know if things are as clear-cut as you posit, but I definitely appreciate the research and attention you've put into this.

Whether it's ethical or not, everyone is coming to the realization that Facebook ads suck. There have been many explanations, mostly of the hand-wavy variety surrounding the intent of users on a social network vs a search engine, but this is the first theory I've heard about how the mechanics of Facebook itself are creating specifically low-value classes of users.

Now obviously you're never going to get an honest response from a customer service rep as their hands are tied. However, if Facebook are smart, their top ad guys are deep at work investigating your claims. Being able to increase the real value of clicks is absolutely essential for the future growth of Facebook's ad platform. If they jealously guard the information gap, then it will hurt them badly as everyone comes to their own conclusion that Facebook ads are worthless. They need to make sure that doesn't become the conventional wisdom.
No. But there's no easy way to tell the difference between "a self-taught guy that has the confidence in his skill to ignore the degree requirement and apply anyway", and an idiot who didn't read the ad properly, and the latter are sadly far more numerous.
