How do you create a poll ad on Facebook? I thought you had to get a sales rep and drop $25k to do that...
When someone "intelligent" gets a bad grade on a math test despite having studied hard, they realize that something is wrong with the way they studied. Or that they have a deficiency in earlier material that they need to correct. Or that they need to sleep more before the test. Etc.

No, actually. When a gifted kid has been praised for their intelligence, it is common for them to generalize a failure into a shameful personal defect: they have let everyone down by failing to live up to their Potential. (And with that high IQ they can generalize very well indeed.) This can result into fear and crippling risk aversion, or conversely manic overachievement.

... "intelligence" is the end product of many years of effort directed at the process of learning and thinking, not something that's doled out of a box at birth.

This is crystallized intelligence, specialized knowledge that can be applied to specialized problems. It is indeed the result of long, dedicated study and practice. However it is built on a foundation of fluid intelligence (IQ) which mostly is doled out of a box at birth.

Learning to work hard is not a worthy goal on its own if you don't learn to work better at the same time ... This is as true in programming as it is anywhere.

I think that "work hard" in this context was meant to mean you should depersonalize failure, so that you don't stop working because of shame or worry.

That's an incredibly mean-spirited "review". The rest of the blog is filled with similar bile... the author has some issues with feminism.
> "We started formally distributing free apps in early 2005 and are among the pioneers of the modern direct-to-consumer (D2C) app store distribution space when the iPhone was just an R&D project in Steve Job’s head."

> "GetJar has been using the term “App Store” in press releases and in it’s positioning with consumers, trade, analysts and press since early 2009 and it’s only now that Apple has decided to send us a C&D."

Is it just me, or is this actually a good argument /for/ Apple owning the term "App Store"? People keep making the claim "it is an obvious name", but apparently it wasn't for GetJar: it wasn't until Apple gave that term meaning by applying it to their product that GetJar decided to use the term.

> "In conclusion, GetJar won’t be subject to this kind of bullying. We’re not going to “Cease & Desist”. We were here long before Steve & Co. We were built by developers, to help developers."

As for this statement... I don't know... this entire article somehow makes it sound like Apple is telling them to stop running their service, when in fact all Apple is doing is asking them to stop using the term "App Store".

I mean, seriously: my full time job is complaining about Apple being a closed ecosystem, but there's something about this blog post that is off-putting and misses the mark; in fact, I don't even see how Apple being a closed ecosystem is relevant to this specific argument.
Thanks for sharing your story dude. I'm sure it wasn't easy.
FACEBOOK FEATURE:ENABLING GROUP CHAT
Sales cycles can be a real problem, especially if the average sales cycle is greater than your runway.
My company has a week long hackathon every 8 weeks. I'm new to the company and so have not participate in one yet. But in asking about them they are seen as very positive. Many hackathon ideas make it into the product (some have been absolute game changers) or improve company processes/tools, they make the developers happy, and give an outlet for where more interesting and/or controversial ideas can get a chance to air.
Lessons learned, experience gained, time to move on and start another project - All the best!
Not sure why, but they removed the feature a while back - http://techcrunch.com/2009/01/04/facebook-quietly-pulls-poll....

It was really slick when I used it, though it did get small samples (100 max I believe) and perhaps people just clicked randomly to get rid of it.
I can't believe this shit appeared on the HN. The author of the post is a jerk: Leah and the team have developed a beautiful alternative to IRC. I use Convore on daily basis.

Think about performance

for (var x = 0; x < im.getWidth(); x++) {
for (var y = 0; y < im.getHeight(); y++) {

That would repeatedly call the get*() methods, and for a 1000x1000px image, that is a lot of calls. Better call them once and then use variables for the loop boundaries.

var w = im.getWidth()
var h = im.getHeight()
for (var x = 0; x < w; x++) {
for (var y = 0; y < h; y++) {
The approach of WeScheme is very different, but they provide syntax highlighting and saving code files. It'd be great if this guy can borrow some of their work.

This article is a little jumbled, but not exactly wrong. In most of the article, "renewables" excludes hydropower; in another it includes biomass and hydropower.

For the main claim ("Renewable energy tops nuclear power in the US"), the relevant data is the second page of this PDF: http://www.eia.gov/totalenergy/data/monthly/pdf/sec10.pdf

Nuclear and renewables are each being consumed at a rate of around 8 quadrillion BTU per year, while fossil fuels are around 80.

The breakdown within renewables can be summarized as:

* Solar: 0.1 quadrillion BTU/year
* Wind: 1 quadrillion BTU/year
* Hydropower, biomass, geothermal, waste: ~7 quadrillion BTU/year

(I only think it's interesting to break out solar and wind in particular because the rest of the article talks mostly about the huge investment going on in solar and wind.)
I'd say that "teachers make shit for knowledge workers". Yeah, they're not going to the poorhouse (provided they can find a job in the first place and get entrenched), and there are a lot of problems with union contracts, but if you're educated enough to get a masters and good enough at teaching/politics to make it through the first few years, you probably could've made more money elsewhere.
Your insight into performance is obviously good, but I'd rather see the students focus on writing code which is obvious to them and have the compiler/interpreter realize there's a ton of redone work. I think you can do this with flow analysis.
don't we already pay a gas guzzler tax?
> This could definitely be abused if someone orchestrated a large purchase & return campaign

I don't think so. For a very popular book, the resources needed for this would be enormous, as there would be thousands of other, legitimate buyers.

For less popular books, noone would bother anyways.
I'd argue the main reason it failed was it was a bad idea. Their was no market for your product no matter how well you made it.

Try not to take away execution lessons when the idea was poor. The execution was fine and if you'd have used a good idea you'd be doing reasonably well now.

As an aside, does anyone have links to other startup postmortems?
Should you use CSSLint?
that's why it's important to stick to the minimum viable product philosophy.

That's the problem with monopolistic/dominant companies... They just don't care. Neither about their customers, neither about their business partners.

G+ vs. FB FTW!
the compiler also needs to figure out that getWidth() and getHeight() are pure.

but yes, i agree with you that for an intro class, students should focus on writing clear code and then optimizing for performance later.
how about this... if a product manager hands you a spec with mockups and youre expected to return pixel perfect code in return, you're on the engineer end of the scale.

the key difference is freedom/autonomy.
Nice writeup! I agree with you - I love reading post-mortems. Success stories are worthless (too much survivor bias) but post-mortems really tell me something.
Failure is a lesson learned. Now you know a few things that don't work so next time you'll know to be cautious about 'em. All the best!
> My friends also tell me that I’m almost a different man these days than even two years ago. The most striking quote to me, from my best friend: “You look… healthy.” Apparently the old day job was beating me down so thoroughly that I looked about as bad as I felt, and even on those days when I wasn’t dog tired I walked with a bit of a stoop. These days, I even stand straighter. I think that is almost too convenient to be true, but hey, it’s a story.

Could be testosterone; it's extremely sensitive to status changes, see the review "The Role of Testosterone in Social Interaction" (abstract: http://www.sciencedirect.com/science/article/pii/S1364661311... ; PDF: http://dl.dropbox.com/u/5317066/piis1364661311000787.pdf )
How about, instead of creating arbitrary fuel efficiency standards, we just tax gasoline so that people consume less of it?

Fuel efficiency standards do virtually nothing to reduce gasoline consumption; they just make people buy gas-guzzling SUV's instead of gas-guzzling cars. The problem is, SUV's are heavier and less maneuverable than cars, which makes them much more dangerous to other cars and pedestrians.

If the government actually cared about carbon consumption, we would have something sensible like a gas tax rather than absurd fuel standards with a huge loophole for "light trucks". The thing is, I'm pretty sure the fuel standards thing is basically a subsidy for American car makers, who make lots of SUV's, but can't make luxury cars nearly as well as the Germans or the Japanese.

I wouldn't say it was a total failure. You learned something, and you can always reuse code (such as the 700 lines for credit card payments) for other projects.
His "me" page explains that he's a database engineer at Facebook, and before that worked on performance-oriented systems and software at Wikipedia. It's part of his job to be aware of the drop in flash costs and employ it where he can while balancing performance with operating costs and expenses. No one is arguing that flash memory isn't as permanent as disks, but it's certainly not as cheap, especially on the scale of data that Facebook has.

Every year or so Stonebreaker feels compelled to come down from his ivory tower to troll industry. Remember a few years ago when he co-authored the paper "MapReduce: A major step backwards" (http://databasecolumn.vertica.com/database-innovation/mapred...)? Nevermind that Google probably processes petabytes of data using MapReduce every day that ends up getting served on practically every Google property. How can he argue with results? Can't we just ignore him?
The first line of this article is:

I believe they are overreacting, but on the other hand, if they don't cease, the cost of a litigation by apple might hurt them significantly.

What i dont get is why apple doesn't just rename their store to something distinctive, since it's obvious they are going to create lots of confusion by using 2 words that have been extensively used in the same business and similar contexts in the past, and they'll keep stumbling with that application. It's not like their new name won't become a household name within a month (given the extensive media coverage they get).
Why Twitter Should Buy webdoc If Apple Won’t
Could be right there :) Inference from either failure or success is tricky.

That said, I think "not knowing my customer" is still a sound lesson. If you know your customer, you'll know whether there is or isn't a market.

They claim they already own and have owned it[1][2]. The legal proceedings have yet to conclude on the matter so we don't yet know if that claim will be honored by law.

Edit: citation added :) "App Store" is considered a "Service Mark" trademark fwiw

Edit 2: another citation listing Apple as the *applicant

Edit 3: correction, apparently Apple cannot "own" the trademark until it becomes a (R) registered trademark? Nonetheless it seems they can still dispute the use of it as is currently happening with Apple v Amazon.

Edit 4: "The owner of a registered trademark may commence legal proceedings for trademark infringement to prevent unauthorized use of that trademark. However, registration is not required. The owner of a common law trademark may also file suit, but an unregistered mark may be protectable only within the geographical area within which it has been used or in geographical areas into which it may be reasonably expected to expand."[3]

1. Teachers start treating everyone as smart

There are two independent factors here:

1.a. Assuming the students have a high IQ.

1.b. Assuming the students can benefit from being like and paid attention to.

If you actually read the article, you find that they are talking entirely about 1.b. One of the student groups is African, so they have a mean IQ around 85. Vanishingly few of them are going to be studying calculus prep at age 13 (option 1.a.). They also explicitly state that they are teaching using techniques used for gifted classes, not the subject material.

So what they are really doing is moving kids out of warehouses and putting them in actual, you know, schools. Amazingly it turns out that an average IQ of 85 is enough to learn useful things.
Failed or not, this will still be very valuable on your resumé, when or if you apply to other companies.
from the tech point of view you have an open platform to share and annotate scanned docs. Sort of "web 2.0 Sharepoint".
The niche that I see for such a service is legal. Lawyers can receive, annotate and remark on clients drafts for proposals, contracts etc.
So it's something like Scribd+ or Docstoc+, for closed network of service provider & his/her clients, where a lot of paperwork is required. Legal services seems like the case.

It shouldn't confuse students with optimization advice, but with the authority the lecture holds on malleable students, your asterisk should still be mentioned as an FYI for good measure.
Your company wants you to work more, so it has this "you must be in office for X hrs every day" and then they realize that people are spending 0.3x of their time in the canteen, so they decide to exclude canteen time, so the employees start playing games at their terminals. They decide to ban games - employees turn to facebook. Ban facebook, everyone becomes unproductive and grumpy. The company decides that this hrs. policy isn't working well, so decides to get rid of it. The joy stricken emloyees run wild and no work happens.

At Twilio we've held internal hackathons with great results. We usually do them when we have a new product that we want to test internally before releasing to a slightly wider audience. This has helped the whole company get familiar with new products which leads to good feedback and better support once the product is live.
Hi Tim,

I would argue that the majority of your target demographic doesn't have the inclination to put disposable income into this.

Most of the time, when I needed help, I'd find someone who could help me for free.

Maybe it's different in the UK and other non-US places, but here, IME, there is no large-scale culture of hiring tutors.
People typically hire tutors when they are out of their depth.

Just my thoughts and experiences. I wish you the best next time!
good to see some honesty in the often over-hyped world of startups
It's sad no one ever paid for the service, but if not don't talk to customers or potential customers (people who pay, not "users" i.e. in the sense of people that do not pay), you'll never know what they want. Generally, it's only when people part with cash that you know you are providing value.

However, major kudos for releasing the code and design docs so others can try some tangent, along with the post-mortem so others can avoid similar pitfalls. That's seriously cool and not something I often see people do for projects they invested so much in. Thanks.
The Keepass I remember was too much and too crowded for a simple need of password storing. I then switched to PasswordSafe and realized that it isn't compatible with Linux, so I went to PasswordGorilla. I have tried all types of simple methods but none defeats the simplicity and compatibility of Gorilla. You just need to keep your database file on dropbox or sugarsync or whatever you use to backup. The term "advance password manager" is an oxymoron, I think.
I don't think most posters in this thread realise how many flat-out nutcases there are out there.

My girlfriend's 90+ year old grandma used to be occasionally harassed on the phone because she was listed as "Maria Lastname" in the phone book (in Denmark, where this is common). I can only assume that the callers didn't expect her to be 90+. The harassments stopped a while after she changed it to "M. Lastname".

My conclusion: some people will go pretty far to get in touch with the other gender. If people want to hide their gender online, they should be given the possibility to.
People answer polls on FB (which publishes your answer with your name) with whatever the person they want their friends to think they are would say. No-one wants to appear a cheapskate. That's why everyone said they would pay, regardless of what they really thought. An anonymous poll might have gotten more accurate results.
They have already spent many marketing dollars on "App Store". They are probably just hesitant to write that off.

Before you use a password which is 9,999 in length, make sure the site you're providing this password is even compatible beyond 8 characters. There are password field boxes out there which would fool you by taking your long password until you realize later that they only took 8 to begin with.
The March of Technology
I always thought it was interesting that a lot of the top CS schools seem to use Java as their teaching language rather than C++ (or C). I've heard that MIT is using python (switched from scheme) and I know the University of Chicago uses Scheme. My school (RPI) uses C++, but I don't know anyone else who does. I recognize that the teaching language is largely irrelevant to the material, but I wonder why the departments choose the different languages.

Sure. The trick is to get to 10-12% body fat, which takes a little bit of time to get to, but it's easy to maintain once you're there.

First, a standing desk. I always get fat when I'm sitting down for too long.

Then, as soon as you wake up in the morning, eat scrambled egg whites, a can of beans, with a splash of olive oil. Take a multivitamin, and a garlic pill. Drink a lot of water.

Then workout, repeating a circuit of exercises for 25 minutes. I do 4-day splits, (out of habit, mostly) so 4 days in a row I'll exercise, and on the 5th, I rest. I just steal circuits from the 'net every two weeks or so. The key is intensity. The more intense you make the workout, the better you'll do.

Here's a sample circuit:

Pullups x 5 |
Ab Wheel Rollout x 10 |
Pushups x 15 |
Squats x 20 |
(no rest between circuits)

The rest of the day, I eat as much as I want of meats(yum), vegetables, and legumes, and I drink a lot of water. I pig out when I'm out with friends, which is every once in a while. Opt for liquor instead of beer, though.
That doesn't allow you to target the demographic (undergrad students).
What people usually mean when they say this is that it is impossible to prove a global proposition about the real world. I don't know when the irrelevant word "negative" was added (after all, every "positive" statement can be trivially re-written in a "negative" form), but it's become very popular for some reason.

For example: "There are no orange swans" is equivalent to "All swans are either colorless or colored other than orange." Similar techniques can be applied to all statements.
they did the same for apple TV, i dont see it as a big deal.
Amid Stacks of Paper, ‘E-Court’ Is Finally in Session
1) Everyone who applies for a mark can use the (TM) or (SM) labels to identify the mark is under registration during the registration period. It does not mean the trademark has been registered (which would be indicated with an (R).

2) The citation is just the application. If you look at the TARR record, the application is stuck.

Are you claiming that ownership, in trademark and service mark law, is defined by registration? That is not my understanding. While registration does secure ownership, ownership itself is defined by use, and registration is not a prerequisite for the commencement of legal proceedings over claimed infringement.
