>Getting the information second-hand seems fairly significant.

I meant to suggest that that made it even less significant. The information is already widely disseminated across multiple platforms because its public information. Sure, everyone knows that CL is the original source for the information, but that doesn't meant that only people they say can have the information should have the information. Its public, broadcasted information.

Sure, they can put something on their website along the lines of "You're not allowed to distribute this information", but why does that have any weight if they don't own the information?

We've historically had waaay more engineers than marketers on twitter's growth team. We look at growth less as marketing and more about optimizing (through ux, design, experiment, machine-learning, analytics, etc) all of our possible distribution channels with respect to a set of core metrics.

We lean towards teaching good generalist programmers how to do "growth," which actually doesn't feel much like marketing in day-to-day practice.

The magnet implant is probably way more sensitive vs this binary device, since it's pressing your sensory receptors in your fingers; they can also sense temperature and position changes.
I'm sure it was mentioned at some point in my BBC Broadcast Engineer training but it was nearly 12 years ago now so it could be a be figment of my imagination. I certainly remember there was some acknowledged situation regarding the Netherlands.

There is a lot of physics that suffers from "bad metaphysics" precisely because of its practitioners reinventing metaphysics, in the guise of "interpretations" of physics, when they are unaware of obvious problems that arise, which even a small amount of reading would've made them aware of.

Could you give examples? I'm not sure what you're referring to.

Automatic differentiation by dual number! Really, after I learned it, I wondered why symbolic differentiation isn't taught this way by default. Good use case of operator overloading, by the way.
Yeah, I have in mind more stuff like recent works by Penrose, Hawking, Krauss, etc. I don't have a problem with people abstaining from comment on implications/interpretations entirely, and many experimentalists would fall in that category. But many physicists seem to really want to write about interpretations and philosophy! Only, somehow, they don't want to call what they're doing "philosophy", because they look down on that.
I agree. How do you think that could be circumvented w/o an implant? Electrodes might work but who wants to do that….
Two non-programming product owners feed work to our five-person dev team via cucumber tests. They own the features directory (we make small mods here and there to get them running or to clarify). They're smart, completely capable of mastering Gherkin (Cucumber's dialect) and writing logical scenarios. It's working pretty well so far, 3 months in. We get the features and just make 'em pass!

Here's a sample:

Feature: Manage Credentials

Background:
Given I am signed in as a superuser
And there are 3 credentials

Scenario: Listing Credentials
When I view the list of credentials
Then I should see all 3 credentials in the list

When I add a 4th credential
And I view the list of credentials
Then I should see all 4 credentials in the list

When I change the name of the 1st credential
And I view the list of credentials
Then I should see that the 1st credential's name has been changed

When I delete the 2nd credential
Then I should see all credentials except the deleted one
Yeah, the next time you go to your local yoga class and the local bleached bimbo starts babbling on about quantum physics (for some reason, a favourite subject), ask them if they can solve a quadratic equation. Guess what, they can't. But that is not a reason to desist! The quantum physics banter lives on...

So, learn from these smart people. Fake it and bask in it!
In his bid to get more viewers of his blog, and thus more perspective signups for join.app.net which he links to in every post, Mr. Caldwell has put out more interesting articles on the social space than I've seen in a long, long time.

App.net seems like an interesting experiment, and I support it in theory, but don't really use much of social networks so haven't contributed yet. I think I'm going to give him $50 just to see if he can sustain the same level of output on his blog, as my own little experiment.

Analysis of Reddit and 4chan's social structure
Didn't twitter hire a group of business experts to try and find a way to make some money with the platform? What happened?

Also, why would someone who can program and market (like me) even want to work for twitter? Why not use my skills to make me (and not you) money?

These are not questions to be taken as an attack, but a real and hoest inquiry.

Oh, don't get me wrong: I was served very well by today's standard math sequence. I learned fascinating stuff in precalc, and calculus was a revelation and a profound joy. Prof. Benjamin's argument favoring statistics instead was a tough sell for me.

But I'm a theoretical physicist. As much as I hate to say it, structuring the entire standard math curriculum so it works best for kids like me (or even for the top 10% of students) just isn't reasonable. (Ideally, a solid gifted program could fill that gap.) I think that we agree on that.

I'd like to think that there are ways of introducing concepts from physics or statistics that do highlight the underlying structure of the field, even if the students don't yet know all of the math they'd need to work through the details themselves. If I find a perfect way to do it, I'll let you know!
The press that you see is the result of users being disappointed at the current-state-of-affairs. They don't see it as being helpful for the long term innovation, or short term utility. Some of these users happen to be journalists. Other journalists are reporting it because how this is ruled will be precedence for future cases. I would say that's news.

If you've ever met Eric (Padmapper is a one-man shop), you'll quickly get the sense that he isn't a slick-talkin' kind of guy. I can tell you that it is journalists that approached Eric, not the other way around.

"Clicking "Continue" confirms that craigslist is the exclusive licensee of this content, with the exclusive right to enforce copyrights against anyone copying, republishing, distributing or preparing derivative works without its consent. "

I'm not sure whether your assumption or information was taken first hand from from Craigslist guys, but it doesn't look like that's the current implementation.
The growth hacker has existed since the dawn of time. It is called being a top sales person, and good sales people are worth twice their weight in gold. Someone who can sell and can program is not a growth hacker, but a sales engineer. Think about it...

Huh? At 5% growth per annum, the economy takes 70/5=14 years to double (I prefer the rule of 70). 112 years since 1900, so that's enough time for the economy to double 112/14=8 times.
It seems likely to me that algebra during school is a cause for dropout not because it's harder, but because it's more objective.

If someone doesn't know anything about history, you can pass them along, claiming that they wrote a few essays or something. It's fraud, and any expert can see it, but it's easy enough to ignore it if you try.

But with algebra you can't ignore failure. It's obvious. Even the most basic tests will reveal ignorance quickly.

I conjecture that those people who drop out "because of algebra" are not proficient in any subject.

I observe that the alternatives suggested are less objective and more "hands-on". What does it mean to learn about the consumer price index without learning basic algebra? The only explanation I can think of is that it offers more opportunity to ignore educational fraud.
Hummingbirds Switch Gears to Stay on Course
Never mentioned I disagreed with her. Where did you get that assumption?
I think where you and I differ is that I don't believe that people who use Craigslist are under the impression that their data will be indexed/used elsewhere; I know I've never assumed that, and I'm willing to bet the same goes for the every day person. If I post something on CL, then I expect others to find my ad through CL. There's almost this unwritten social contract that users expect services they use to participate in when they submit their data.

But the more I think about it, I do see that it's not as clear-cut as I previously thought. There are tons of sites that store and display our tweets without our explicit consent, and we, at least I, seem to be ok with that.
Of course, but it would be nice to think that university professors are more intelligent than the general population.
US Census Bureau SF1 API Variables
The news on this was posted on Friday but I've been hammering through the API all weekend. The link above is a summary of all available SF1 variables, an insanely detailed and long list from actual census data.

The Census API also offers AC5 variables which contain information about occupation, income, employment, education, etc.
This is just deliberately overstated language written by lawyers, to give CL maximum legal power if they ever need it. In practice they let search engines index them, and users know and expect that.
This is called a "vibrotactile display". They've been around for quite some time (1970s). In fact, you can make "electrostatic vibrotactile displays" using small electrodes to deform the skin and get much higher density (ie. to make fake, programmable textures) -- these are starting to find their way into cellphone screens. You'll find lots of examples... usually attached to a person's forehead, tongue, or back. Here's some more info:

I think the tippers should get 1 vote per dollar or something. Contributors can vote on TODO lists. This lets the developer get feedback on what the community needs. The developer can do whatever he fancies. But the votes will reduce the communication gap between the developers and the donors.

For example, some posts talk about Puppet or Chef in the title. I didn't recognize those the first time so I look. Having learned something, even though others may know all of the embedded content, I up vote. The next time I may skip over it, having already went through the discovery process, but other people come across it and derive value. Hence the cycle continues.
I rarely comment, but I feel compelled to add to this discussion.

Algebra, as it is taught today in the U.S., is not necessary, and is probably detrimental in many of the ways stated in the article. I can't speak for non-traditional schools, but public schools, with their focus on standardized testing, have effectively destroyed the original spirit behind teaching mathematics.

Mathematics, much like other academic topics (e.g. literary analysis), was taught not as a practical skill, but as a way to improve your abstract thinking and problem solving skills. As another commenter stated, Mathematics (along with most later academics) should be a gymnasium for your brain. I like this metaphor, because if you think about solo athletics, all students are not expected to achieve at a pre-defined level. Rather students are evaluated based on improvement in performance over time.

Sadly, mathematics in recent years has become less about abstract thinking and problem solving and more about rote memorization, computation, and application. I taught basic algebra to college students for a semester. One of my most interesting experiences was with the dreaded story problem. Most of the students were simply unable to apply math to solve a problem. They were all very good all computation, but when faced with a problem in a form they didn't recognize they instantly began flailing.

Standardized testing has turned math into the process of recognizing a form, plugging in the numbers, and computing. We're now starting to see the first generation of math teachers that are a product of standardized testing, and the results are frankly, frightening. I've spoken with younger math teachers who couldn't explain the practical importance of their subject. While they loved math, they couldn't tell me why they were teaching it, other than: "It's on the [standardized] test."

This is the kind of Algebra we don't need.

Incidentally, the only way I avoided the shocking deficiencies of standard high school "math" was by fighting my way into an advanced program at the local University. It was there I was introduced to Euclidean geometry and really learned what math was all about. I think everyone should learn Geometry using the Euclidean method. I learned from a simplified book (Geometry, by Moise/Downs) which starts out with a few more postulates than Euclid did. I'd go as far to say that geometry (properly taught) will make you a better programmer/problem solver/thinker.
Why do you call that crap? A normal bank would do something similar. Try traveling to another country and using your ATM card, it likely won't work unless you call your bank ahead of time and tell them of your travel plans.
Most users use padmapper through the website. CL offered a license only for mobile apps, which, depending on your point of view "a license with a crappy option, but a license nonetheless", or "a license that's completely not applicable".
The NY Times writer reached out to me, not the other way around - I don't have a PR person.
It seems to me like a reasonable generalization of the part where experts don't talk authoritatively about things outside their fields. You have degrees in CS and Philosophy, but I doubt you'd write about as related to your field as CPU manufacture, much less completely unrelated fields like aircraft design or particle physics. Staying out of shakespeare, political science, art history, and archaeology is just a broader extension of the same principle. In the reverse direction, if you know nothing about statistics, using statistics in your reasoning is probably a bad idea, and if someone brings in statistics you should pull in someone that knows how to do statistics so you're not making a decision that you don't understand. "Staying out of things you're not qualified to talk about" could prevent a lot of problems.
But isn't that the downside of working in someone else's ecosystem? That company is going to do what's best for that company, as they should, and unless you have a contract with them, they are free to change how they allow access to the data they collected. Padmapper knew they were in a grey area, they rolled the dice and came out ahead more often than not. But at the end of the day, there's no such thing as a free lunch.

As far as it being the users data, this is true. But the collecting, organizing, publishing and accessibility of that data is a service that Craigslist provides, to the user, in exchange for an unlimited license of that material. I would love it if Craigslist opened up their data, but it just doesn't make any sense for them as a business.

Sales and marketing aren't the same. This is not sales. A growth hacker is a marketing engineer, and I don't think that role has been prevalent until recently. Counterexamples are welcome.
The economy grew by a factor of 1.05^112 = 236. Which is close enough to his number to assume that he missed the "doubling" part of the question. 236 is about 7-8 doublings.

Clearly you are entitled to your own opinion about whether or not you enjoy heroes, but I fail to see how it adds "strategy" to the game.

Total Annihilation is a good example of a game that had a super-powerful unit that didn't completely break gameplay. The problem with Warcraft 3 was that I could build a massive army, yet if my hero was more than a couple of levels lower than my enemy, he could destroy everything I made using only his hero.
Isn't the difference that you can do practical stuff with maths, but not really with literature and art (except, granted, create more literature and art, which might be the only jobs left in the future)?

Perhaps knowing maths is a bit like having dirty fingernails from doing manual labor. A certain class of people is proud of not having to do manual labor, and hence they take pride in their clean and long fingernails. Others will despise them and value "real work" higher.

That's not the only motivating factor, it's more complicated than that (not wanting to see something I've worked on for a few years become less useful, for example), but it was the main one in starting PadMapper, and the main one in deciding to do this. He was saying that CL's actions seem to contradict that mission.

If it makes you feel better, PadMapper is attempting to act in a way consistent with search engines - give a bit of a preview of a listing and then link back to the original. It's not taking the text and reposting it or anything like that.

It's an interesting frontier, but I don't have any good resource that has continual updates on it. Any recommendations? The only other place I've really seen stuff about it is BME Zine, but it's focused on BME in general, so there's a lot more noise than signal.
Reputable password sites can't unencrypt your passwords. You trust the site to not have XSS flaws and to not be malicious. Outside of banking and email passwords, that doesn't seem like a huge risk.
I have a love/hate relationship with books that capitalize on a counterintuitive notion, and that includes Malcolm Gladwell, mentioned in the article. While they're good reminders that many societal preconceptions are incorrect, too often they just replace one misconception with another.

Procrastination is not good. Procrastination is not bad. It's a question of when and why. Perhaps intentional procrastination on some tasks and plans is good, but when you procrastinate on everything, things don't magically become better and you don't get any special insight: you just stop doing what you wanted to do, and over time you end up lagging behind people who don't share your love for procrastination.

Not all advice is good for all people. For entrepreneurs, procrastination is a terrible suggestion. In a small business, if you don't go after opportunities, you may forget about them; they won't come for you. Of course, a good entrepreneur should distinguish between a worthwhile endeavor and a dead end... but someone who adopts procrastination as a principle will leave the trouble of distinguishing between work that's worth doing and work that isn't for tomorrow.

A bad idea doesn't become better when you decide to sit on it and only implement it a few months later. A better advice would be: stop having bad ideas, and shoot dead a bad idea when you see one.
This is hard work, and hard work doesn't get done when you procrastinate.
I am a little confused by the wording of this. I usually think of a growth hacker as somebody who helps scale an app, like an Instagram engineer for instance. Is anybody else confused by the naming?
It's not like the press (ie paper newspapers like the NYT) is a neutral party in this - craigslist has pretty much destroyed one of their largest traditional sources of revenue (classifieds).
