Here I'm really interested in lowering barriers to mathematical education.

Target:

I'd like to see created for the JavaScript community, an equivalent of the Python-based/linked scientific and high-performance computing libraries (great lists of which are available at http://sagemath.org/download-packages.html, http://wiki.python.org/moin/NumericAndScientific). And I want that, because I'd like to make it easy for people who learn JavaScript to get into scientific and numerical computing without having to learn Python (& company). (I know it's easy to learn Python, as I basically did it at some point, but this suggests that perhaps it'll be easy to compile some restricted subset of JavaScript to Python.)

Hypothesised method:

I'm primarily interested in a new language with minimal difference from JavaScript, because the market ("human compilers") I'm targeting are programmers who already know JavaScript. What I want to target those people for, is to give them a minimally different language in which to write code that compiles to faster C, in the manner that RPython and Cython do for Python. I'm willing to throw out a lot of JavaScript features, I just want to be careful to add a minimum number of features back in. I'll definitely be looking at Lua, Dart, ECMA Harmony (which has no formal date of release, or am I mistaken?), etc. as these are all close resemblances to contemporary (2012) implementations of JavaScript.

Questionable Motivations:

I'm personally willing to learn any language/toolset that gets things done faster (I'm learning Erlang myself, for this), but here, I am specifically interested in lowering the bar (sorry) for other people who may not have such willingness. This is just one of those "want to have my cake, and eat it too, so I am putting some time into researching the problem" situations. I have very limited prior experience in computer language design, but so far from a hacking-the-ecosystem point of view, the problem seems interesting enough to study, so, I hope to be doing more of that soon.

I've lived long enough to see unemployed engineers, ex NASA rocket scientists, programmers after the .com bust,. The more specialised the profession, the harder it is for the person to find work when the economy drastically changes.

The smarter a person is, the more likely they suffer from the myopic perspective that things will be different for themselves.

In particular, young people make all sorts of uninformed choices based on the biases of people around them. For instance, youths are exposed to 8 hours of indoctrination that school and the life of the academic represents the highest ideal. But look who's telling them?

The same goes for startup communities which glorifies sleeping on the couch. Ideals and realities are often two different things.
I do believe standby and hibernate are different as standby keeps memory contents hot whilst hibernate actually shuts the computer completely down. I was talking about the former in my post above.
Is there any reason coffeescript can't be extended to support the same thing without parentheses? That feels fairly natural to me since it's similar to the object literal syntax.

Edit: Couldn't find that this has ever been suggested before, so I created a github issue: https://github.com/jashkenas/coffee-script/issues/2307
I don't know about DiskKeeper, but I believe it's part of the "Lenovo Enhanced Experience" on ThinkPads. Amazingly, my factory install with crapware booted from pressing BIOS to Windows desktop in just over 7 seconds. I haven't been able to get my clean install below 10 seconds, I think because I'm missing the filesystem tweaking.
Brazilian here... For now, not many people, as mobile internet doesn't have a lot of penetration here, unfortunately (about 20% last I heard) and even in areas where it does, the quality of the phones still isn't very good, with many people accessing the internet with the old feature phones instead of smartphones, and the (mostly android) smartphones are barely capable of running Angry Birds).

But it will grow a lot, with forecasts saying it will be about 60 to 70% by the end of 2014.

For now, mobile internet is somewhat restrict so showing some initiative in this area is good for the C&A brand, because it associates it with a feeling of status, which normally doesn't come when one is thinking about C&A. So good for them. I haven't seen the hangers in the stores yet but will check them out (and try to see the counter going up) soon.

What a strange example to choose since this is actually precisely what fast food companies do: the food at mcdonalds is designed around keeping you hungry despite eating it (its quite literally JUNK food). For example, a Coca Cola contains a ton of salt as well as sugar, so that your thirst is not quenched in the same way as drinking water. I'd list more examples but there is just so much literature around this now that a simple google search should suffice (even just watching Supersize Me would be a good start - -This movie is actually very related to your point as it deals with how McDonalds used to ask you to supersize, which is clearly a proactive position in making you eat vs. just not turning you away).

But even beyond that, there was just recently an article on how McDonalds is introducing snack wraps because they perceive that the best way to grow now is to convince people to eat at McDonalds BETWEEN meals as well. The article was basically centered around "where does the biggest fast food chain go from here?" (looking for link and will edit shortly if I find it). If you look at the advertising behind these new additions, they are trying to train people that they should eat these snacks in-between their other existing meals, "on the go". So basically, you're hypothetical is actually not devious enough: they've already been so successful at convincing their target market to eat all their meals at McDonald's that they now need to create new meals in order to grow!

Edit: I believe this was the article: http://management.fortune.cnn.com/2011/08/23/why-mcdonalds-w...

There's probably a way to programmatically add that for every underscore function, but there's probably not a _good_ way...
If hibernate is quicker than a clean boot on OS X 10.7, you either A) need an SSD, or B) need more RAM.

Hibernate takes a full 48 seconds on my laptop. A clean boot takes 8-9 seconds.
Good point. Connections make the situation even worse (for aliens). Interestingly, it's about the same for humans: 3-4 entities produce 3-6 connections. Both are in the same neighbourhood. The limitation is biological though (http://en.wikipedia.org/wiki/The_Magical_Number_Seven,_Plus_...).
Wow, you got me there. "Working Effectively with Legacy Code" would be even more directly in-line with what I'm looking for. Way too much Java EE stuff in the code base I'm working with right now.

Thanks for the comments, jorgeleo. I do believe my boss had my best interests in mind, but you're probably right that it's easier to put someone "in a box" than it is reconcile the nuances of someone who evades classification. And hey, I don't blame him; I like to organize, classify, and categorize stuff, too. Everyone does. I think it's just human nature.

But your overall point is well taken. I'll focus on doing good work and try not to worry about where I 'fit'.

Well as a matter of fact, the colleges really can't get enough people to teach. This is why there is such movement towards online super-sized lectures: they want to teach an order of magnitude more people (charging them for the service).

The problem is that university administrations have tried to transform their institutions into profit-making businesses, and have insisted on cutting corners. They are hell-bent on the notion of teaching an order of magnitude more students without hiring any more tenure-track professors.
His point isn't that everyone can do it, obviously that's not true, but that there is nothing about it that requires a multi-billion dollar company. To wit, the barrier to entry is low.

Yeah, zCloud only came into fruition late last year. Before that they were using AWS, and handling the same scale they do now. Private cloud is saving them money, but some other company could use AWS just as Zynga did before and handle millions of users absolutely fine.
> I do not know about medicare per se, but when social security was designed to support people 65 and over, I think life expectancy was around age 62. So it was designed to support a relatively small number of retirees in their extreme old age. Then people began living longer.

This is true, but the real problems with Social Security began when Lyndon Johnson combined the Social Security fund, then entirely separate, with the rest of the federal budget. Instead of maintaining a very close eye on how much money was coming in and going out for Social Security, there was no longer any urgency to keep that money around. In other words, money taken out of paychecks for Social Security was spent on everything else, and Federal income taxes were paid out as Social Security.

Don't get me wrong, this is cool and helpful, but in my opinion this website is absolutely not okay:

> Since I started working at Dwolla it became clear to me that payment fees are really confusing. I put this calculator together so people could easily understand how different payment system fees compare.

To have this tucked away on the little "about" page that it's being ran by someone with a connection to one of the companies listed seems wrong. If this was presented as a tool from Dwolla then sure, that's fine, the bias is made clear at the start, but to masquerade as independent isn't okay.

Even if the intentions are 100% pure this is still an advert for Dwolla from Dwolla (each employee represents the company) and not making sure every viewer understands that is wrong. Not to mention Dwollas pricing structure is so that you can never not have Dwolla as #1 in this...
How will failing a class impact you in the long run?
So I am probably going to genuinely fail a course for the first time in my entire life. Has anyone else ever genuinely failed a course despite asserting your regular amount of effort in the course? My class is Modern Physics and physics is one in fact one of my majors. How does failing a course impact you in the long run?
We already have enough taxes to pay for roads, education, and emergency services. What we don't have enough money to pay for is a huge government bureaucracy which ends up being a money pit.
There's a Nova episode about the effort to prove that a portrait was a lost da Vinci.

An important part of the investigation was Elisabetta Gnignera, a costume historian and expert in renaissance hairdos, identifying the bound ponytail of the girl in the portrait as being a style that only ever became prominent in Milan, and only for a few years--the same years when da Vinci served the Milan ruling family as artist and engineer.

I thought it was cool that there are people who are experts in renaissance hairdos--and that their knowledge can actually be put to practical use.

(There is much more than the hairdo evidence to tie the painting to da Vinci. It's worth watching the Nova episode if they show it again. The combination of historical research and modern scientific analysis was quite intriguing).
In the early 2000s I joined the WELL. It didn't last long. Nobody was having any interesting discussions there. Conversation that went much beyond trite pleasantries was invariably choked off by tut-tutting oldsters telling everyone that everything had been said before.

Over the course of the 2000s, I've had a chance to watch several online communities that I was deeply involved in grow old and die through the same process. I've decided that it's just part of the natural life cycle of an online community for it to die at the hands of its most devoted followers through this sort of intellectual smothering.

So it's maybe not tragic that it should happen to Stack Overflow. It's just sad that it started happening so soon.
"why piggyback on someone else's success?"

Dwolla is awesome, but this comes off as an ad for Dwolla. I suspect most merchants will be dismayed to learn that asking your customers to pay with Dwolla requires them to sign up with a new service and link their bank account.
Racket didn't opt out of R6RS. Racket has multiple language modes, one of which is actually R6RS Scheme. It also has a "legacy mode" for R5RS, along with modes for a handful of other languages such as Datalog, ALGOL 60, and some teaching languages.

So I don't suppose I could persuade anyone that education is a public good?

The whole point of this is to be as neutral as possible. If you look at the source code, which is btw available on github (https://github.com/Dwolla/fees-calculator), you'll see that I haven't hard coded anything. Which means that if one of the other gateways happens to be cheaper for a given scenario, they will be on top.

I understand where you're coming from, but again, the whole point was to try and stay neutral.
I think your underestimating things, someone that can dump 350k on one of these is probably richer than around 99.99% of humans who have ever lived.
From what I have read, it is complicated, probably too complicated for me to ever debate off the cuff. And I am especially not qualified right now.

This may be somewhat irrelevant, but what is the motivation for having a case-sensitive HFS volume? I agree that Adobe should support it (and separate volume installation) because these are edge cases that should be accounted for, but I've never heard the reasoning for having a case-sensitive format.
Slightly more sickening is that for some of their apps it can be fixed by simply renaming directories and libraries within the App bundle. I googled around for a bit a few months ago and got PS and InDesign working on a machine with Case Sensitive formatting. This sort of laziness just kill me.

One example of the tail wagging the dog:

Strictly speaking, `main` isn't even a special function in C. It's only special to your C library and linker and something something I forget the details. Anyway it doesn't matter at all; you could leave off the `if` in Flask's example and never notice any difference. Just emerged as common practice to bracket off stuff like that /in case/ you ever decide to import your script as a module.

Part of my problem with PHP is that it doesn't seem to know what it is; there are the C parts, and the C++/Java parts, and both sides are sort of glued together with Perl influence, yet don't very well interoperate otherwise.

I have a pretty patchwork background and I could get work done in just about any language you'd pay me to use. I'd even happily write a web app in C. Doesn't make PHP any more attractive.
I still like ActionScript because I like javascript, but in many cases I want to declare my types so I can get type checks at compile time instead of being surprised or having to write unit tests to be sure of myself. Also refactoring large javascript or python projects is my nightmare because getting it to 'compile' means nothing, so many bugs could be lurking still.
Over-generalization much?

A lot of HN'ers either work in startups or founded one themselves. I'd say that will put them through enough adverse experience to know what they're talking about.

Tried playing around with it and got a serious error in calculation.

Did $100 average per transaction + 500 transactions annual (made up numbers) and I got the following fees PER TRANSACTION:

$125 |
$1375 |
$1600 |
$1850

That's clearly not right...
That would preclude the vast majority of the Democrat audience from posting. On the other hand, it would go a long way toward reversing the trend of HN becoming more like Reddit.

Can you please explain to me how this oversight on my behalf makes the situation better? Does the fact that Google is also disallowing client-side A/B testing of this fashion cause it all to make sense? Seriously: you can tell me I misunderstood the article (which I will happily admit I skimmed: I read the various paragraphs as "different common mechanisms for implementing split tests", one per paragraph), but can you honestly tell me that this misunderstanding would have changed anything about my rant, excepting possibly making Google come off even worse?

^ This is the reason why I went in that direction, by the way. This is a video from Matt Cutts, one of the many that I sat through watching during a massive five-hour- MattCutts-and-GoogleWebmasterHelp -a-thon that I force myself through a week or two ago. I am hotlinking to 3:23 into the video as this video answers multiple questions (as is common on the MattCutts channel, as opposed to on GoogleWebmasterHelp, where each question tends to get its own video).

In this question's answer, it is clearly stated that Google may very well consider the same page returning different loads of the page for purposes of A/B testing as "cloaking", and that webmasters should instead use client-side mechanisms to perform these tests. If tests /are/ done, it is claimed that the webmaster should only do so on areas of the site that are not being indexed (which may involve explicitly telling Google to stop indexing that part of your site).
