Very few commenters think this is a good idea. The majority of posts lament the rote learning and lack of understanding involved. Why then, is this upvoted so much? Is it that people think the comments are worth reading so much that they upvote the article in the hope that other readers will read the comments? Are the people commenting negatively upvoting the article in the hopes their comments will be more widely read†? Are people afraid of flagging articles?

The only place you could build up is San Francisco. San Jose is problematic due to the airport. Sprawl probably wasn't the right word, although the Lucas thing was sprawl. It's easy to say SF should build up but maybe the residents don't really want that?
Boston suits HubSpot as a company. Because it is such a big, diverse college town they have been able to hire great, hard-working sales and CRM people right out of school, which is truly that company's core competency.

It's not their engineering that has made them successful but a combination of sales/CRM and evangelical style marketing. I'm not sure SV could provide that - but please correct me if I'm wrong.

I see.

The server side support seems like the wrong thing to base the protocol design on, but I admit that is probably just me showing my limited experience with very high traffic api's. I would think though that much of this could be alleviated by proper caching. As requests would naturally be finely granulated into individual resources, presumably that could be done efficiently.

The point of browser support is probably more pressing. I'm curious as to how big an issue that still is? Which browsers support it properly these days and which don't?

I wonder if it would be worth to build an api around the assumption of support for pipelining and then provide a fallback hack for those that lack support. E.g. something similar to the good old _method hidden-field hack for lack of http method support. I'm thinking something like an optional "batch request endpoint", that would tunnel through multiple requests, similar to what a pipeline would do. I believe Facebook is offering something similar in their api's.

You're not wrong. "Zero tolerance" swept the land and there is precious little the average person can do to change how schools work. Running for school board requires a commitment that most people cannot accept (need to feed the family).

This whole thing is pretty much why I support parents picking the school the kids go to with the money following that choice. It is really the only way that parents will be heard.
Demand for babies is much higher than supply. Once they're toddlers or older, that trend quickly reverses.
Fastmail reworked their UI recently as well (shortly after the Opera takeover I think). I preferred the old UI which hadn't really changed in years, but the new one isn't too bad. I do 90% of my email in Emacs though, and only use a browser when I'm on a platform where I don't have ssh.

I hadn't heard of nReduce. Very interesting. My take is that if you are accepted to YC and are willing and able to move to SV, then there are clear benefits in doing so: network, external validation, brand, access to capital, etc.

If you are not accepted and/or are unable to relocate to SV, then a MOOC version of YC makes sense for the reasons that MOOCs make sense in higher ed: location & time independent, high quality learning, structured peer review, clear milestones and deadlines, tuition free, and most importantly ... it is far superior to the alternative, which is often doing nothing.

I cannot tell if this comment is ignorant or genius.
>Copyright is nearly useless in a world where there is an infinite supply of any given work for negligible cost.

The entire point of copyright is that copies cost significantly less than the original. For example, no one has a copyright on a well cut diamond, because there would be no point. However, if after you put in however much work it takes to cut the diamond, people are able to make perfect duplicates at little to no cost, then you need copyright to protect your initial investment.

The only reason it is easier to buy works than pirate them is because copyright does exist, so there are additional barriers to getting the work in a way that the author does not want. As it is today, people buy books through publishers. If there was no copyrights, why should those publishers pay the author anything?

At least in the U.S., there really isn't a surplus of children to adopt. Adoption is actually supply-constrained. There are about 130,000 or so adoptions per year in the U.S. as compared to 4 million live births.

As population growth stabilizes in the developing world, and contraception and abortion become more widespread, adoption is going to become even less of a practical alternative to having ones' own children.
There are precisely 2 ways to interpret the linguistic meaning of the statement, depending on the whether you insert "decisions" or "options" for "choices".

With what you're thinking of, the actual reaction someone has to the statement, after deciding what is linguistically intended... I've got to believe there are a lot more than 3 possible reactions. One that you haven't mentioned is the tendency to immediate demand a differentiation between "good poor" and "bad poor". This was one of the less brilliant innovations of eighties political culture in the US.

You're assuming the same set of people that are commenting are those that are upvoting this article.

Another hypothesis is that those are two largely disjoint populations on HN. With the smaller one displeased with the article and is likely to express that in comments. The other, larger one is pleased with the article and doesn't bother much with comments.

'disgust' is interesting and not necessarily rational.

Your point is pretty much impossible to discern as well. All I see in your post is slagging off DPR as a glorified drug trafficker, and some rather vague handwaving about the "realities of the drug trade".

"Irresponsible drug manufacturing"? If you're imagining that SR is a cesspool of tainted products, you could not be further from the reality of it. On SR, buying communities for specific drugs or drug subtypes tend to band together to discuss and assess vendors and their products quite publicly. In some cases, you see users subjecting vendors' products to lab tests (in countries where it's actually easy and legal to, god forbid, quantify the exact composition of illegal drugs). It's nowhere near as easy to get away with selling tainted garbage in this venue as it is on the street. There are typically far fewer unscrupulous operators standing between buyer and the actual supplier on SR, and consequently product quality is higher than most buyers likely have access to IRL.

> sooner or later be ruled by the ones who can produce the best product for the cheapest price at a high enough volume

..and? If the guy who can produce untainted, good-quality product at the cheapest price wins (which he won't, as there are any number of other factors that people involve in their buying decisions), then why would that be a problem?
> San Francisco liberal.

Having grown up in DC and now living in SF I think this phrase is farcical as well. SF liberalism is pretty shallow and restricted to a small number of topics (gay rights, environmentalism, and others). The cities off I-95 between DC and Boston tend to be more liberal on issues other than the Californian's one to three pet causes. Of course on an individual by individual basis there isn't a total monoculture in either place, and it's probably more complex than a binary liberal/conservative distinction.
Take a sample of 100 random felony cases against black defendants and 100 random felony cases against white defendants prosecuted by this specific prosecutor during a specific period of time and where the defendants were from similar economic backgrounds. Then show that all things being equal, black defendants were prosecuted more aggressively than white defendants.

In other words, approach this as if you were a scientist and take the emotion and assumptions out of it.

Like I mentioned in the blog post, we have a messaging problem. Though the blog post really wasn't intended to communicate that message. Ha.

Our product is an email marketing toolbar that sits the bottom of your blog or website and can accept email addresses onto an e-mail mailing list. So, let's say you run a company called Widgets, Inc, and a part of that is you have an email list that gets an email each time you post a new blog. You could add an Anchor Tab to your page as an elegant way of getting users onto that email list. (They enter their email onto the bar at the bottom of the page and it's added to your Constant Contact or MailChimp list.)

Does that make sense or am I just perpetuating the fail?
Really? I found the front page very clear... They make a bar that you embed on your website and that allows people to subscribe to a mailing list.
It is open for debate.

The question does not say cut "into thirds," it says "into three pieces." This - http://i.stack.imgur.com/kEjP0.png - is a perfectly reasonable answer which, assuming the rate of cutting is constant, would result in 15 minutes.

It's a bad question.

Edit: That said, I would have given the same answer as the student, because I think that's the most reasonable interpretation, especially considering the illustration. But the keyword there is "interpretation." The question is ambiguous.

The demand for toddlers might be lower than supply, but the whole market of older children is a small fraction of the overall adoption market, which is a small fraction of the overall child market. Each year, only about 20,000 kids age out of foster care without being adopted, versus about 70-80,000 babies who get adopted, versus about 4,000,000+ births.

In any case, adopting an older child is a huge undertaking and not something someone should do just because she wants a child. These kids often already manifest issues resulting from parents who are drug users, etc. They need much more support than your typical child.
I think sliverstorm's point is that just because something is risky doesn't mean it is a scam.

There isn't a country with enough police to protect everyone from physical harm caused by others at nearly all times (statistically speaking)? I doubt it.

Your comment highlights the problem. When people think search they think Google. Search is bigger than that and Google is in a way through its success and utility, limiting people's imagination when they think about search.

"It allows users to create a block level disk backups and restore it with ease"

If one takes the time to select optimal pivots it becomes O(nlogn). The selection is free from a big-O perspective, because it's O(n) immediately before the O(n) list division step.

Of course, nobody does this, because the selection is not really free. The constant factor cost of choosing the optimal pivot hurts the average case, making the modified quicksort tend to do worse than heapsort or introsort.
Can you back up that assertion?

This actually isn't true for Common Lisp.

There is a distinction between reader macros and compiler macros, for example, which is relevant for allowing using special syntax be optional for end users.

Certain things also need to be defined if you want them to be available in the compile-time environment. And, sometimes you have to do a bit of extra work if you want to have literal objects in your compilation environment and pass them to runtime.

Educational books is something that really could work fantastically well with open source models. Some group of people prepare best current practice chapters for a single topic. This group includes educators (to know where children get confused and make mistakes) and experts (to spot subtle errors, and to 'foreshadow' knowledge needed later).

These are released.

People can make corrections.

For something like math this could have significant impact not just in the US and EU but in the developing world too.

PS: About the fraction multiple choice: There's probably a bad joke about 24% being what we'd expect if we let the students chose at random. I'm not funny enough to think what it is. (The punchline being that there are 5 options, not 4.)
It is expectations and habits. On Android devices, people expect to get applications from Play / Amazon stores rather than manually downloading and installing an apk. I expect that a supermajority of Android users by a huge margin would not even understand the concept of "download and install an application package" even though they do it every day on Windows. They see Android, they go to the app store for programs.

It seems likely that no one taught those students how to think about math.

I.e. teaching students the steps to solve a math problem is not teaching them how to think about the problem.

I instantly knew 12/13 + 7/8 was ~2 because I visualize two pie charts in my head, both of which are mostly full. This is in contrast to the other way to solve the problem, converting the fractions to a common denominator and then dividing by the denominator. It would take me some time to do the latter, whereas I can instantly do the former.

I don't think the students who got that wrong (nor some who got it right) do any kind of visualization in their heads.

Teachers need to realize that it's the operations in the head that count the most, not rote memorization of steps to solve a problem.
Thanks for the feedback man! And yeah, I guess part of our problem with the Hellobar comparison is that we're solving a problem they've been solving for a small subset of their users for awhile.

They're really optimized for "I have a user on a page, and I want them to go to X." X could be a product information page, or a page to add their email to a list. We're optimized for "I have a user on a page, and I want them to put their email on my X list so they can get my updates." where X is the name of your email marketing service. That distinction means we can get some tighter integration and a few more UX brownie points for that use case than would make sense for Hellobar to implement.
