Intelligence Is Overrated: success has nothing to do with how smart you are
Great idea in theory but I can only see it being abused by companies.

"Oh, I see you are not on any of the new range of health tracking services that have sprung up, what are you trying to hide? Permiums UP!"

I don't see companies lowering premiums based on healthy lifestyle but making those the new baselines (at today's pricing) and then hiking them for everyone else.
What is the marketplace called that Exec. operates in? Some hybrid of on demand service, personal assistant.

Of course, not sure if such a service operates in PDX...
whoa this is a hell of a demo. hats off!
It could already provably handle the load of millions of Chrome users (cf. SPDY: https).

And it's not like it's totally separate from their normal http infrastructure, which could also already provably handle the load of billions of searches.
Essentially you are saying something is better than nothing.

I wholeheartedly agree.

As a person whose purpose in life is more and more "Free information in order to Free Education", all I'm saying is I think we can do better; a lot better.

Rote memorization certainly works. But I don't think anyone anywhere, has ever proved that it's an efficient or even particular good way to learn something. And yet modern civilization takes this for granted.

p.s. I never went to college so this is all outside-in.
Casting a watchful eye upon in-game currencies
Use this instead:

$('#myProgressKnob').val(_new_value_);
I might have rephrased, "It's very difficult to help the poor unless you also get off their backs".

Perhaps it's not helpful to think "everything will be better if those people get off our backs", as you mention.

But I'm a U.S. citizen, and I've only recently given up bananas for good. When we're the ones doing the oppressing, it's also not helpful for us to pretend it doesn't exist.
Any thoughts on writing up similar articles about more advanced nonlinear filters, like particle filters?
My TV has rabbit ears. I can watch NFL games in high definition with them for free.
As well as this story turned out, surely it's a bad idea (assuming you're not an evil criminal) to just hand someone else's immigration documents to a stranger to return? Sure, Exec vets its people, but it can't be perfect. What's wrong with either 1) doing it yourself after the meeting, or 2) turning it over to the police? Yes, the return will be delayed, but there's a significantly lower risk of personal info being compromised.
I sure hope the scrolling in your new interface is not as laggy as on your pitch page...
Anyone else think he meant exec (3)?
Hi teach - would love to hear your feedback after working through it for a semester. Feel free to shoot us an email!

Obama Gets Huge Twitter Boost After Gay Marriage Support [CHARTS]
I am a student at codeacademy, I am 41 years old and I have had always the urge to learn programming, I have tried many online tutorials in different programming languages and @ first it is exciting but later on it gets fustrating and finally I get lost, codecademy has given me hope again that i dont have a disability in programming, yes I get stuck and I have to do the exercises 3 or 4 times until I grasp.the concept, but I can feel my progress and I am allways excited to take the lessons every day
Woops! Thanks, fixed.

There are a variety of reasons:

* Safety - not everyone protects their website from XSS attacks

* Speed - Downloading 30 or more script files from all over the planet slows down browsing

* Tracking/privacy - it doesn't make your browsing private, it cuts down the more obvious things - https://www.youtube.com/watch?v=f_f5wNw-2c0

* Principle - browsers render HTML - nobody should be forced to require javascript ONLY to read the content or just to have access to the correct
page. If you have fancy effects or some additional functionality or if it's required to provide core functionality (e.g. maps) then fine, but JUST rendering text?
How To Find Memory Leaks
I'm not defending the Spanish conquest - it would definitely be cool if the Incas and Aztecs had been left alone. Not that the Incas and Aztecs were exactly paragons of respect for human rights, you know. (Or do you know?)

I'm simply observing that the quality of government by the late pre-revolutionary period, ie, the 18th century, is a lot higher than the quality of government in the 19th and 20th centuries - by almost any sane metric.

For instance, it's my belief (maybe not yours) that the main purpose of government is suppression of civil violence. If your government fails at this, nothing it succeeds at much matters. Now, imagine the progress of Mexico over the last two centuries, absent pervasive political and civil violence. Don't forget - the first university in the Americas was founded in Mexico City in 1551, almost 100 years before Harvard.

You appear to have been inculcated with a lot of very complex explanations of the tragedy of post-colonial Latin America, whereas my views, obviously, are quite simple. This is no accident. I'm a big believer in Occam's razor. I don't feel it's necessary to construct any intricate explanations of why the Flying Spaghetti Monster doesn't exist.

It's not at all unusual for people living in a historical period to misunderstand it completely, generally as a consequence of political corruption. This is as true of the late Roman Empire as of the late Soviet Union. My feeling is that historians of later eras will understand our world much better, and much more simply, than we understand it ourselves.

I'd strongly recommend reading at least one anti-liberal history of this period into which you've put so much study. It'd be a shame to come away with such strong conclusions when you've only heard from the prosecution. Elsewhere on the thread I've recommended Waugh's Robbery Under Law (1939) - not hard to find and very easy to read.
I recognised that one as a horn, but I had no idea what the connection to post is, and still don't. Just took it for one of those weird corporate logos that meant something to someone at some point but doesn't anymore.
Yep, I have a friend that has send them an email (using his uni email address) for a few days now. Apparently no answer ... Hope they are gona improve the feedback.

On the other hand on RubyMotion Google's group you can get an answer directly from Laurent Sansonetti if you have questions.
Thanks for this nuanced and thoughtful feedback.

Our tool is a new way to present information, and the course creator community is figuring out how best to take advantage of the format. You wouldn't write documentation in the same way that you present to a crowd of 2,000 people, and you won't write a Codecademy lesson the same way you write a textbook. It will take some time to use the platform to its full advantage.

I'm excited to see what innovative courses the community comes up with, and I would love to hear your suggestions about the product or curriculum. Feel free to reach out directly at sasha at codecademy dot com.

I don't mind the "extra blurriness" all over everything on my screen at all

Add that many of us roll at a zoom level != 100%, immediately undoing all of this pixel-perfection work. Only when you're targeting the iOS devices do you have any realistic control over pixel to pixel mapping.
The Young and the Relentless: Entrepreneurs Under 25
CS Lewis said that ""All language about things other than physical objects is necessarily metaphorical." I can't find the examples he gave, but from your sentence: we must "discover new means of interaction that take advantage..."

"Discover" is made of "dis-cover", meaning "remove the things covering the other thing." The "inter" in "interaction" implies movement between objects in a physical space. To "take advantage" evokes physically grasping something.

Perhaps this is more philosophical than you wanted, but I doubt we'll be leaving behind physical metaphors anytime soon.
Makes me wonder how old the author is.

Reminds me of an anecdote I read about an elementary school that had a rotary phone for the kids to use well after digital phones were the norm. The kids had to be taught how to use it. One child ultimately concluded it was not too different from a digital phone though it was real slow.

Reminds me of my standard flippant remark to my sons when they were growing up: "When I was a child and had a pet dinosaur and rotary phone." To my young sons, both dinosaurs and rotary phones were "prehistoric" -- I.e. existed before their time. For me, only dinosaurs were actually prehistoric.
I really like the interaction on my iPad with a couple small issues: don't jump with I first touch and don't allow wrapping from max to min.

Alternatively, I don't think I would want to use a mouse with these.
As someone who has lost immigration documents before, I heartily approve of whichever method you choose to get them back to me, regardless of whether that is a) handing it over to a secretary, b) handing it over to the cops, or c) handing it over to the first foreigner you meet on the assumption that all foreigners probably know each other.

That last one lead to a truly surreal telephone conversation with someone who, well, speaks Chinese a lot better than I do, but we did eventually get it sorted out.
This reeks of PR fabrication.
Probably a really common oversight and valuable advice (Read Zuckerberg v. Winkelvoss)
Kalman filters are a simple idea when viewed from the right angle, at least for someone with a good grasp of linear algebra.

You have a linear dynamical system with normal-distributed dynamical noise. You then take linear measurements of that system over time, and again those measurements are subject to noise that is normally distributed. The question is then, given the series of measurements, what is the best estimate of the state of the dynamical system? When written out like this, it's just a least squares problem. What makes it efficiently solvable is that the matrix structure is block tridiagonal. If you apply the block version of Gaussian elimination to that block tridiagonal system, you get the Kalman filtering equations. That's all there is to it.
Road safety is a maybe, air quality is a theoretical as the numbers are so low. Contrary to popular belief, most of the cars weren't 70's gas guzzlers but late '90s models with relatively efficient fuel injected engines.

The energy used to create and deliver the new cars far exceeds the energy used to continue using the old ones.

There is no defending this insane scheme unless you want to get into partisan politics and go for the symbolism of it.
Are Smart Phones Spreading Faster than Any Technology in Human History?
"Oppression" is dangerous terminology to use when no actual physical intimidation is taking place. When peacetime gets labeled "oppressive", people begin to see wartime with a different set of eyes, and the country gets thrown into a cycle of violence from which it is difficult to get out of.
Awesome! Thanks for contributing.
Sorry, but Andrew really is that good of a guy. The Exec who picked it up happened to be in our office when he did, so we asked him to snap some pictures (with the parties' permission) in case it turned out to be a story with a happy ending. Which it did.
exactly. in my experience, management hardly ever holds themselves accountable for their decisions. That might be an east coast thing though. :)
Using OpenKeyVal (http://openkeyval.org/), the bookmarklet looks like this:

(function(){
var data = { data: location.href }
jQuery.post('http://api.openkeyval.org/myownkey', data)
}())

And on each client you have a screen-sized iframe + an "update" button that triggers:

$.getJSON('http://api.openkeyval.org/myownkey', function(data){
iframe.src = data
})

You have to remember to use your local IP address, not localhost. I ended up making a small nodejs server so we could use websockets and drop the update button.

I can safely assure you it is not fabricated. I was here in the office this morning when the call came in. We were all pretty surprised about the nature of the request.

FoldIt Game’s Next Play: Crowdsourcing Better Drug Design
Indeed - and it goes much further than just the prices in regional USA or Europe.

Some guy in Africa will be wondering why his cab fares mysteriously went up, and will have no idea that it was a vote-buying scheme halfway across the world in a country he'll never visit.

Some of the cars scrapped were worth several thousand, and would have lasted for years, both as serviceable vehicles and donor vehicles to keep others on the road. But they were forcibly destroyed and scrapped, taking all their parts with them.

The scheme, in all its incarnations around the world, was stupid and destructive.

Jeremy Clarkson summed it up best with his quip 'we'd be better off giving everyone in the Taliban a decent used car if they promised to stop shooting at us'.

Not really for ratios. If there's a min and a max, sliders make sense.

You can make a better argument for a knob if you have an unbounded range, or an effectively unbounded one (making small adjustments on a large scale). Think old iPods.
What I find really odd is that you have no statement of such on your web page. I search the entire thing and I can't tell if you ever plan to release an Android library. As a developer it shapes my perception of you as not a cross platform play but an iOS play and immediately rules you out for just about anything I would do. If I was you I would at very least have a note in your libraries section that Android is on your agenda.
Don't trust police.
Correct, each object is on a separate timeline for purposes of operational transform. If both clients are connected at the time the changes are made, then it shouldnt be possible to see the second change before the first. We keep an ordered history of all changes to all objects, though for efficiency, if a client that wasn't present when changes were initially made syncs, changes to multiple objects may appear in a different order. For example, a modification to object A, then object B, then object A again, would appear in the correct order for all clients when those changes are made. If a different client then syncs and asks for what's changed, we may group the two changes to object A such that there would appear to be two changes, a change to B then a change to A.

There is currently limited support for keeping a subset of data synchronized (we have plans to improve this) - if you're using the client libraries in an app, we've focused on supporting the common case of keeping all the data per bucket for a user synced. In the case of keeping all data mirrored to a backend, we provide an endpoint per bucket that you can listen to all changes for all users so you can keep the entire data store synchronized.
I consider myself an "average" person teaching himself to code and the first thing I did was make a commitment to aggressively imbue the activity into my lifestyle for the 'I need to learn to think like a programmer" reasons you mentioned. I don't believe you can truly "learn" this stuff any other way. It needs to become habitual and the easiest way is to absorb it into your day to day existence regardless of how irritating or slow it may seem for the first...three years
If you want to understand Kalman filter in simplest term, check out the article at http://credentiality2.blogspot.com/2010/08/simple-kalman-fil...
How about the C language? stdlibs api are still under copyright so the author could sue the FSF for the GCC, Apple for LLVM and whoever use C.
I went back to see what you were talking about and now I'm in the same boat as you. I think it's a good opportunity for another cool effect though. I imagine you could hover (after "kudoing") and the animation would happen in reverse resulting in an "un-kudoing".
What is the brown text editor used in the video? Is it only on Mac?
I wrote the underlying article - thanks for catching that I wasn't using 2007/iPhone as the timeline base.

The 2002 date was when I was saying smart phones reached general consumer availability, not when the very first one was invented. As I mention in the article, it was 2002 when Blackberry phones and Microsoft Pocket PC phones came out, as well as the aforementioned Palm-based Treos.

FWIW, here's the source article: http://www.technologyreview.com/business/40321/

The thing about those is that ultimately the city-by-city approach is a distribution strategy. A single jamaba juice can exist on its own.

For Uber or 42Floors to succeed with venture backing, they really need to dominate a large market (like all major cities in the US). Thus the pitch still becomes much more high level and not focused on individual units.
Okay, but why would we pick a stupid way of looking at it?

In the Mexican Revolution you have the divide in America between mainstream and radical liberals (Woodrow Wilson and Eugene Debs) mirrored almost perfectly in Mexican factions (Carranza and Zapata). The only indigenous Mexican forces are, by definition, people like the Cristeros, who have no foreign base of support. Viva Cristo Rey!

Also, the period is a little different, but Walter Millis's The Martial Spirit is an excellent deconstruction of the Spanish-American War, which leaves both the imperialist and humanitarian strains in US interventionism (rather uniquely combined in that war) in hilarious tatters. It's 1931, but archive.org has it:

Flash Stats of the Week—Flash Game Market Survey 1 | Official Sothink Blog
In college, I listened to some advice about choosing less experienced instructors because they have more recently been through the same material that they are teaching. Plus, they'd be more motivated and less jaded. Turns out that the experience factor is not that important.

At this point, after having many mediocre teachers and very few good ones, I've come to the conclusion that only a small percentage of "teachers" are actually worth learning from.

The only good teachers I've had were meticulous about their knowledge AND really loved teaching. Not one or the other.

It basically requires a full-time teacher. Anyone besides that is actually worse for me than no teacher because they are apt to ruin my interest in the subject. Maybe I'm spoiled, but most classes aren't much better than a textbook and a chat with a good friend.

Who does that leave as worthwhile teachers? Rare people like Feynman, a couple of instructors on Lynda.com, one or two from my undergraduate classes, and a couple from the new array of online classes. Again, you can be a grad student and be a great teacher, but you have to know your domain inside and out, and love teaching it. That means fielding questions with ease and, probably, being able to teach without notes if needed.

One of the reasons I like open online courses is that you get to experiment until you find an experienced professor who had enough initiative to start an online course in the first place. I really do mourn the downfall of the in-person class setting, but at least in my experience, a vast majority of them aren't what they're cracked up to be. Maybe at top 10 schools the situation changes?
well, the name of the company is a play on the exec (3) command, so in a way, yes :) it's also short for "executive assistant", so we have lots of double meaning going on.
I don't know about Japan, but I suspect that in most major metropolitan areas in the US b) has roughly the same chance of success as dropping them out of an airplane.
This is unbelievably cool. The demo video is worth watching, for anyone who doesn't get it.
No, it is much more than that. You should watch the video, it demonstrates the platform solving some very hard problems with very little code.

The key here is (I believe) operational transformation (http://en.wikipedia.org/wiki/Operational_transformation), the algorithm behind products like Etherpad and Google Wave.

The observer pattern only handles the case where you have one client accessing the datastore. OT expands those ideas to handling multiple clients. Sync is a really hard problem, which is why almost nobody can get it right. Simperium seems to come closer than most and is packaged in a nice service.

It's really exciting to imagine the possibilities.
Fair, but I was more alluding to the fact that shifted elements, while a nuisance, don't necessarily cause a site to stop functioning like JS can (assuming I'm working on a JS-heavy web app).
I like this a lot. I wish there were smaller starting shapes, or that you could draw a starting shape with your cursor.
i've always found that subpixel antialiasing looks horrible
Regulation of (social) game mechanics
Watch the demo video. You can resize the shapes by just dragging, it's actually really intuitive (if only we hadn't been trained that only little dots at the corner mean you can resize or rotate!).
Don't these anecdotes just reenforce patio11's point though about the difference in mindsets?

These two anecdotes describes places/bosses that seem completely toxic. It's trite to say "in the end you don't want to work at a place like this, they did the well-meaning guy a favor" but it seems to be true - some environments/teams/people cannot be saved.

This mindset is self-defeating in the end, and I don't see why it deserves to be reenforced.
I'm going strong on codecademy. It's great to have a structured approach to learning. There are so many resources out there that it's difficult to even begin to learn coding. I don't expect that this will ultimately teach me to build products with code but it at least will introduce me to common/core languages and provide a base to continue my studies through other means.

Right now I'm working through the classes nightly. 15 badges down...no clue how many to go.
This is non-responsive for me at the moment, how does this compare to http://www.contextfreeart.org/ ?

Is it a visual interface to define the rule system, rather than the programming language approach? If so does it escape the same traps that other visual languages fall into?
It's an app store for apps that only run inside the Facebook app. Facebook is a platform in a platform - the "Inner-platform effect".

http://en.wikipedia.org/wiki/Inner-platform_effect

"The inner-platform effect is the tendency of software architects to create a system so customizable as to become a replica, and often a poor replica, of the software development platform they are using."
That isn't necessarily true. He doesn't specify rotary phones.

Even if he did, like the folders and envelopes he also mentions, corded phones which look like the picture are still quite common in office places and thus many peoples lives outside of silicon valley.
