(Author here) - I don't have any specific examples, but I was learning R and Python at the same time. I found Python to be very practical and easy to learn. When learning R, I kept getting tripped up. Maybe it isn't that R was harder, but that I had a head start on Python. And as for documentation, R was certainly very complete, but once again, I found it harder. I think because R is written by, and probably for, professional statisticians and mathematicians, it needs to have a different level of rigor than the Python documentation. Anyway, sorry for the lack of specificity.

Their license used to be horrible for commercial use, but mostly because it was an extremely bad fit for a data collection, leading to lots of confusion over what was ok and not.

A better comparison for their current license would be the LGPL - as long as you keep your proprietary data separate from the OSM data, you don't need to release it but you still need to release any changes to the OSM data itself.
I'm actually not aware of any systems where they vote for a party. Could you give specific examples? A quick romp through Wikipedia yielded nothing, but I was probably searching through the wrong area.

It seems like the author is taking a specific subset of ed-tech ("online learning companies that rely on the student's intrinsic motivation") and trying to generalize it to all ed-tech.

There are TONS of different companies doing some really interested stuff in ed-tech. Not only are there lots of ed-tech companies that aren't online learning companies, there are a lot of online learning companies that DON'T rely on a student's intrinsic motivation: e.g. anything in the K12 space - there are a lot of K12 schools that are beginning to incorporate online learning into their curriculum, and then there's plenty of extrinsic (e.g. grade-based) motivation to do well and perform.

I think my #1 takeaway from this is that the author isn't the target market for most of these ed-tech companies. They're not trying to get people to take these classes for fun, no more than colleges want people to take classes for fun.
You should use the "this page in other versions" mechanism at the top of the page you linked to so you can see more recent documentation: most of what PostgreSQL has with regards to replication is from versions more recent than 8.4 (the version you were reading).

http://www.postgresql.org/docs/9.2/static/high-availability....

(I'm curious why you want to do replication for dbmail: it would seem like what you really need/want is partitioning; e-mail metadata, especially with effective indexes, requires a lot of write throughput, and synchronous replication is going to largely cause the same write load on all systems.)

Having read pg's book (ANSI Common Lisp) and all of his articles; I liked this question and the answers pg has given.

I agree with forgotusername's opinion about the luck plays a good part in life, but as long as the Viaweb's concerned, the luck had its minimal share because I still remember in one of pg's articles he was talking about how frequently they have written their code base in order to serve a user experience better than the competition. That's hardly got anything to do with luck.

And if you've ever read all his articles, you might have spotted sections talking about when and how the luck has been playing really impressive role; and there you got it: In the case of Bill Gate's Microsoft. How it suddenly became a multi billion dollar company almost overnight is plain luck.

Also when you consider for how much Viaweb was sold, which was about $50M, and compare it to other sales most of them as high as ~$1B, again there is no luck to be talked about.
Or... Google could open source their software, leverage the thousands of volunteers and let a giant leap be made by both, their own projects and OSM-related ones.

I suppose you mean "make no money", assuming PDFs are off-the-net stuff, which is quite likely.

A couple of years ago I got a Kindle DX for technical PDFs, and haven't used it much past the first year - it's not really pleasant to use. It combines the size/weight disadvantage of an iPad 10" (not the upcoming mini ;-) with the slowness and poor resizing of eInk.
"The same was said of Berkshire Hathaway for the majority of its run under Warren Buffet, a success that has recently begun to wane."

Where do you get the "success that has recently started to wane"? Berkshire Hathaway has continued to outperform the market, check 5 and 10 year charts here for example: http://www.fool.com/quote/NYSE/berkshire-hathaway-inc/BRK-A/....

Obviously they haven't had the same level of outsized successes, simply because BRK has grown much bigger, and it's harder to get good returns on larger amounts of capital. But there's no way you can conclude from Berkshire Hathaway's performance that it was just luck after all.

Also, see cs702's comment about how Warren Buffett identified 7 investors in 1984, all of whom went on to outperform the market: http://news.ycombinator.com/item?id=4476166
The model used by Coursera, et al is far from the only model for online education.

Expecting future education to work like a traditional lecture class (just online) is far too limiting, IMO. To name just one alternative among many, consider sites like StackOverflow. Educational? Absolutely. Fits the traditional model where there's a smart guy standing at the front of the room (real or virtual) and shoveling the same knowledge into every student's brain at the same time? Not in the slightest.

There's probably going to be a continuing role for courses and course-like entities, but those shouldn't be the only thing we work on (and I would argue that they shouldn't even be the primary things we're working on). The lecture model was developed to deal with a set of constraints that are largely irrelevant in an online environment.
Speaking from the point-of-view of someone who already has a bachelor's degree, I have found it hard completing free online classes — the majority of the time I just scan through the lecture notes and assignments. On the other hand, my dad (who has two master's) has worked through almost a dozen MIT courses — and normally reads through the accompanying textbooks.

The one course I found truly useful was Stanford's iOS course (it really is one of the best iTunes U courses available). Other than that, I'm much more likely to watch a single lecture (think TED or Stanford's lecture series on YouTube) than a whole course.

Sure, I mean `me@yahoo` is an RFC-compliant email address, it refers to a local server 'yahoo'. However in your online app it's almost certainly an error if this email address turns up in a registration form.

Don't test for an RFC-compliant address if you don't want to accept all RFC-compliant addresses. Being able to send an email is a much better test because it matches what you're going to use the email address for in your app.

In a political climate where a major state's dominant political party's platform wants to ban critical thinking skills because they "challenge a student's fixed beliefs" and "undermine parental authority", it is unthinkable that scientists could be in government.

Typically, a critical mass of the populace equates science as being anti-God, and critical thinking as being conspiratorial.

To answer his question, yes virginia, we (people that use MySQL) use replication a lot. Especially at mid-grade levels of scaling where custom sharding and replication middleware hasn't necessitated itself yet but vertical scaling is out of the question.

I'd say the bigger issue with Postgres now is that middleware like http://code.google.com/p/vitess/ for it hasn't been deployed in the large yet. Most Postgres scaling anecdotes I've heard were:

"Well we put 64 gb of ram in the server and installed a RAID array of SSDs and stopped writing dumb unindexed queries."

Well that's just dandy, but what if my indices don't even fit in the ram of a single machine?

Y Combinator Founder Paul Graham Issues New Warning to Start-ups
(You mean proportional system, not parliamentary system.)

But first-past-the-post with single member districts means that everyone elected has to be, personally, a good election campaigner. And scientists, by and large, make terrible campaigners. They think that being right about an issue is enough to win the point, which is more or less true in science, but absolutely not at all true in politics.

To expand on what aidenn0 said:

It's possible to do client-side known-public-key verification, which would detect a MITM attack. The idea is basically maintaining a local trusted cert list (other than the broad ones in the OS), but using known site public keys instead of root signing certificates (which I will admit are a security nightmare for SSL).

Chrome does this for Google-controlled domains; they call it "public key pinning." I'm not sure if any of the other major browsers do it, but it would be pretty simple to implement.

Even if the government had a root CA-signed cert for "mail.google.com", Chrome would throw an error because the government's signed cert public key would not match the public key pinned inside the Chrome browser source code. Chrome would barf with a certificate error.

Sorry, I should have been more precise. The general public does not have rights to personal information an individual has declined to share. Now, this obviously excludes public information which the individual wishes wasn't available (arrest records, political contributions).

I agree with you that the presidential office has made executive orders and signed bills recently (Obama and Bush both) that have substantially increased governmental reach and reduced privacy. But this doesn't give the public to take what they want willy-nilly. It does give the public the right not to vote for someone they feel has a double standard on privacy issues.
Hey, at least it keeps TI in the consumer SoC business. It's not like they've had that many OMAP4 design wins, OMAP4 is long in the tooth at this point, and OMAP5 isn't with customers yet (to the best of my knowledge).

But your way, if the user makes a typo like "foo@@bar,com" then he will expect to receive an email but wont. Better UX in my opinion is to do validation before sending, both client-side and server-side (esp. good for REST JSON APIs), then if these are all good send the welcome email.

A couple of peculiarities in the study that place Java at a disadvantage:

1. Examples using outdated low level concurrency primitives such as wait and notify. Use of java.util.concurrent would have made the code much more terse and safe

2. Java performance affected by use of the outdated java.util.Stack class. It is well known that this class uses redundant synchronization. The docs recommend using a Deque implementation instead.
The name is rather unfortunate; it sounds like "paperweight."

We are trying to capture a customer's satisfaction within a few key areas an also overall. This is why customers are only surveyed every 3 months. We find this gets a much better idea of how happy they are with the service.

There are other tools for capturing feedback immediately after signup or a support incident, which would help identify signup or sales issues. This is an area we may look into in the future but for the moment the focus is on measuring change in their individual opinion over time. This lets us identity customers that still rate us well, but their opinion has dropped over time. (Or people who are rising advocates etc)
Why don't Americans elect scientists? Examing Data on historical samples, may be instructive.[1] Some of the mor salient points to note, after reviewing the sample data:

(1) A 'Science' criterion is Neither necessary nor sufficient;

(2) Political geography is not most likely a relevant issue.

Indeed were it so, the relative newness of 'Science' would imply there were no good leaders among the Ancients -- clearly an error.

(3) Other examples: Presidents w/ Engineering Degrees.
Ulysses S. Grant (1869); Dwight D. Eisenhower (953); Jimmy Carter (1976).

So, data and logic imply we start from a flawed premise. Science of course, would not disqualify you, provided you had the political skills. But the correlation is not assured one way or the other. To the extent its relevant, it may not be explanatory.

Ask HN: Best startup marketing ideas you've come across this year
Thanks, I hadn't even noticed that link at the top.

(To answer your other question: at the moment our mail load isn't severe enough to pose a problem for synchronous replication, and I'm just aiming for the ability to have multiple mail hosts share the same mail data with no single point of failure. As the mail load outgrows current infrastructure, I'll start partitioning -- although I haven't figured out how to do that just yet. I've considered a distributed file system, but hammer has only just recently started to look like it's up to the task.)
I see that the API you feel most people would want is validate_2822_addr (aka validate_addr), which validates an addr-spec (as people should really not be typing angle addresses with display names into forms asking for their e-mail address ;P).

However, that specification, and the implementation you provide, is really designed for parsing e-mail address headers (as you say: for an MTA/MUA), and so contains a bunch of properties specific to structured MIME fields that really has nothing to do with e-mail addresses.

Instead, if you are verifying an e-mail address that someone types into a form, you probably are looking for "the kind of e-mail address that SMTP would accept for delivery", and that is covered by a different standard with a different and unrelated grammar.

Specifically, you implemented RFC 2822, the successor to RFC 822 that has now been obsoleted by RFC 5322, the standard on "Internet Message Format" (in essence, MIME). The related RFC 2821, the successor to RFC 821 that is now obsoleted by RFC 5321, is for SMTP.

For an example of the kinds of differences this would cause, RFC 5322 (with errata) believes that ""@example.com is invalid (by errata), but hello(ignore)@example.com is (MIME comment); RFC 5321, on the other hand, believes the exact opposite validity.

(edit: When I realized that I should probably write a blog post about this, given how much time I've put into implementing this stuff recently, I realized that there was more to say on this general subject, and I'm including it below.)

That said, I will go even further: these formats are designed for escaping e-mail addresses in the context of a larger standard and protocol, one that might already have special characters. This is why they contain so much quoting support.

This is then why the grammer is often so highly restricted for things that don't need to be quoted: given that an @ cannot be found in a domain name, you really shouldn't need to quote anything to the left of the @ to get a valid e-mail address.

However, "(" is a special character in a MIME field (begins a comment), and thereby if you want to include it in the local part of an e-mail address, you will need to escape it somehow; the same is true of things like whitespace, commas, or angle brackets.

The user typing the e-mail address into the form, however, isn't dealing with these restrictions: asking him to escape special characters in his e-mail address seems silly: one might as well be asking people to HTML escape their username in the username field.

That said, there is then a separate RFC 3696 which talks about the semantics of contemporary e-mail addresses and how one might go about validating them, and it includes the idea of quoting in its implementation (so maybe it believes that RFC 5321 is king).
