Although I've been using it for a while, I have to say it's very limited, and editor support should be out of the box, not via plugins as, for example, the Sublime Text plugin make your file redraw as it changes the settings upon opening and it's not very pleasant to the eye.

I think it should be extended to more common features and then if an editor doesn't support one, by spec, it should ignore it.

> The problem is that the current IPK has lost a tiny bit of weight, in comparison with 40 similar cylinders held in other countries, which is a significant flaw in an object used to define a unit of mass. So the Avogadro Project has created two softball-sized, near-perfect spheres, made entirely of silicon-28 atoms, that should remain exactly one kilogram in perpetuity.

I seem to remember reading a while ago that no-one was quite sure why the reference kilogram was losing mass. Why should one therefore be confident that the new spheres will not do so?—or is this another 'distortion for convenience' of the article, like:

> Lie group E8, for instance, is a set of 248 different forms of symmetry that apply to a theoretical 57-dimensional object.

E_8 as a Lie group is 'continuous', and therefore infinite, and E_8 as a Weyl group has size much, much, much bigger than 248. The number 248 presumably comes from the dimension of the Lie group E_8 (and I suppose that one could twist words to accept that the dimension of the Lie group is somehow a reflection of the "number of different kinds of symmetries" that it contains); I'm not sure (but am not an expert on this, and so might just not know) whence comes the 57.
Apologies for not responding earlier. As indicated in a sibling post; yes, I believe most language recognition is done with the old style. Mainly because it is fast and works for the majority of use cases, though, and not because it is required to be that way.

I understand, on principle, why this is not ideal. In practice, I have trouble disagreeing with it. I do find autocomplete nice; though, I have also found that in the instances where I'm having to rely on autocomplete, I'd have been better off using the documentation of whatever I'm doing for a bit to actually have solid grounding before embarking on code.

My point was exactly as the sibling said, that this is by no means all emacs can do.

I agree with all of these changes. Code-style-wise, I prefer to call the actual handler implementations `handleFoo` as opposed to `onFoo`. It's a very small detail, but it makes code a little easier to sift through (as well as search/replace), because you always know that `onFoo` is a prop (whose implementation is foreign to the component) and `handleFoo` is a method (whose implementation is native to the component).
I want to warn people that sites such as that linked here cannot possibly predict the direction of the real equities market in a reliable statistical sense -- apart from the outcomes one might get by flipping a fair coin.

This is common sense -- if the operator of the site actually had an inside track on the market's workings, what possible reason would he have for revealing his findings to the public, instead of privately investing his funds based on his genius insight?

One answer is that the site's operator might have a position in the listed stocks and hopes to trick people into investing in them, thus enriching himself at the public's expense -- the so-called "penny stock" scam.

All speculation, of course. But for those unversed in equities trading, sites like that linked here are utterly without value, a fact demonstrated by the now-famous WSJ dartboard Contest:

It's impossible to imagine where computer science, biology and physics would be without the tools and the methods of inquiry that statistics provides.

Wow, I was floored by the average cost of ownership. Mine is nowhere near that low:

1. $0. I don't have payments is 15 years old, so it's not depreciating significantly.
2. $1250. I fill up about once every two weeks. Old cars have less safety features, which me ans better fuel efficiency. 25 mpg.
3. $0. I've never had an auto loan.
4. $300. Old car and perfect driving record. Still have good coverage (uninsured motorist, etc.).
5. $500. Here's where an old car starts to bite.
6. $355. I have no clue so I'll go with what they said.

Total ownership: $2405. That's not significantly more than riding the bus would cost.

There are courses on youtube [1] which do a good job of covering a lot of the theory (disclaimer: I haven't finished the linked-to course, but what I have finished has been informative). If you're interested beyond that, you can look into some hardware, like the OpenBCI [2]. The consensus is that the hardware is more expensive than it should be, although so are the alternatives.

Once you've gone over some of the general resources, you'll have a better idea of what specifics to research.

The places where I can't use my American Express have been almost non-existent. One or two mom and pop restaurants were Visa only, but that is about it.

Almost all of my monthly spending is on my American Express.
The biggest flaw is the assumption that people who live in cities where Uber is available drive an average of 13,476 miles per year (with avg commute distance of 25 miles).

Those numbers are the national average, but I'd guess the average miles per year is significantly lower for people living in major cities.

When I lived in rural New York I easily drove 10-20k miles in a year. But now that I live and work in San Francisco, I drive about 3-4k miles per year, with a daily commute of 7 miles round trip.

It'd be interesting to see a similar analysis that limits the data set to people who live and work in major cities where Uber is available.

I mean "embedded" as in a "scripting environment hosted by a bigger app" (nothing to do with embedded systems in hardware sense, obviously). I thought the term is widely used for this, for example there's a guide to "embedding python"[1] and they use the same term in Lua[2].

For me, such an environment is defined - in practical terms - by the lack of some features you expect from "general" programming environment. No stdout/stdin, no fork, no exec, no file and file system access, no threads, no sockets - and if you get some of this it's via an embedding app, not standard means. It's hard to work in such an environment because it's very rare for app developers to provide you with all the standard tools you have when developing standalone program. One of the most painful experiences I had with such env was with Google Refine - now Open Refine - which allowed scripting in Python (via Jython) and Clojure, but only really supported executing single statements in a tiny textbox, without any real error reporting and without access to anything external (like to files). It was a nightmare, and it's generally how this looks like: MS Office, Web browsers, Emacs are the exceptions here, definitely not the norm.

Because most people aren't in it for "fame and recognition" or "vanity"?

If I find a bug in a piece of software, or something misconfigured, I tend to report it and move on. I don't try to hide my identity before reporting it. A security vulnerability is just a bug or misconfiguration, that happens to be exploitable for nefarious purposes. The responsible thing to do is to notify those responsible, and anonymity doesn't help with that; they may need to follow up to ask questions to find out more details about it.

While there are some people in the security community who are prima donnas, who try to hype them selves and their exploits to gain recognition, this case does not appear to have anything to do with that. This is someone who sent a private email to those responsible, and then started seeing articles online and getting complaints emailed to his college about irresponsible hacking of other institutions websites in front of students.
"In fact, he believes one day all the Uber cars on the road may be driving themselves."

What piece of "cars driving themselves" does Uber have? Uber has an app. Google has self driving cars and they can also build an app. So he is basically describing Google's future, not Uber's.

I see single-speed bikers as the luddites of cycling. I live in a relatively flat city, Dublin, but I am still constantly shifting gears. I think a lot of people don't understand how good gears really are. In a similar way, there are a lot of people cycling mountain bikes around the city, and I didn't appreciate how much better actual road bikes are while I still had my hybrid.
And for non-cyclists: 15 mph (25 kmph) is a fairly reasonable commuting speed.

Fewer safety features /= better fuel efficiency. New cars, loaded with safety feature can get better fuel efficiency than 25mpg.

Regarding the 25mpg, is that a recent calculation or are you going off the info sheet your car had when you purchased it. Unless you took excellent care of your car, I'd bet you're not getting 25mpg.

I found his point of being a young black male and not having to be pulled over again to be striking.

I am sure that black people are pulled over more times by the police then whites are. What could be the reasoning and the solution(s). Is it because...

- The cops are really racist?
- The cops are looking for a suspect that matches those unfairly targeted? In which and unfortunately points to a statistic that black males (those from low income areas & raised without a parental unit(s)) are more prone to crime. In the area I live there are really bad parts of town you do not want to enter due to high crime, gangs, murders, etc and that part of town the majority is black.

Is there a solution because I know I would be pissed just because I am getting pulled over because I resemble a suspect the cops are looking for.

Though maybe the cops are just racist?

Node.js has a very specific purpose - implementing the Reactor Pattern. There is no need pretending that it's a general-purpose framework and emulate alien concepts with it.
Google is not the only company investing in self-driving cars, so there will almost certainly be a market for purchasing them as well as merely renting. Uber has a proven customer base and elegant transition strategy. It should be an interesting competition, assuming Google doesn't buy Uber outright.
Once self-driving cars are available, Uber would be a major company deploying them (assuming Uber is still around and similarly positioned). They could either buy their own cars, or somehow allow private "drivers" to deploy their cars on the Uber network.

Geez, $12,744 per year?

I've had my current car since 2002, which I bought new for about $14,000 (including interest, which was low because I paid the car off as quickly as I possibly could, short circuiting most of the interest payments).

I go through the exercise of the total lifetime cost of my car, gas, insurance, maintenace, all told every year or two. And it's somewhere around $.30-.40 per mile or about $1 cheaper than Uber.

I recently took it in for its 130,000 mile comprehensive check over and it ended with my mechanic offering me $5,000 for the car (I didn't sell it).

It's expected that I should be able to get another 100,000 miles out of this car easily. And at my current rate of driving, that'll be an easy 10 years.

I'm pretty sure I'm going to keep this car unless it needs major mechanical repairs, and so far it hasn't.

All this means is that my cost per mile keeps going down. I'm at well under <$4k per year, all lifetime costs included, amortized over the time I've owned this car and and that number is going down every year.

Right now I probably drive under 5,000 miles per year (telecommuting is amazing) and even these astonishingly hopeful UberX costs (60 mph commute times everywhere in cities bah!) are almost twice what it costs for me to have my own car I do whatever I want with. More realistically, these commute times could easily be tripled in most cities, making UberX even less of an option.

The only thing this answers is "will taking Uber on the occasional 25 minute or less trip cost less than owning a $50,000 MSRP luxury mid-sized sedan?" then the answer is obviously yes.

Honestly, if your starting point is a Lexus, you're not really all that concerned with your transport costs to start with.

edit I don't even think the math is right.

Let's assume his 24.2 mile commute in 25 minutes (haha!). Uber charges $1.10 + $.21 per minute or $1.31 per mile at 60mph. So let's just make the numbers easier, 25 mile commute in 25 minutes, so the commute ~ $1.31 * 25 = $32.75. But I have to go home again in the evening. * 2 = $65.50 per day. * 250 work days in the year = $16,375.

He's off by about $10,000 even assuming these ridiculous commute times.
> Number of consistently successful traders and hedgefund managers do exist.

Yes! Absolutely! Half of them are more successful than chance and half less! In the same way, if I flip a fair coin, roughly half the flips will confirm my prediction that I am a genius -- or that I don't know anything about probability.

This requires a bit of science:

1. There are "successful" investment houses and individuals.

2. What's the reason? Is it stock picking genius? Or is it the blind workings of probability?

3. Easily answered -- if an investment house publishes its predictions, and if the predictions consistently beat the market, then the SEC will step in and arrest those responsible for insider trading.

4. Guess how the SEC detects insider trading. Yep, you guessed it -- they do better than market averages.

> ... so you can see for yourself if Jim Cramer's recommendations are worth listening to.

But I can tell you in advance that they aren't. When they succeed (beyond a chance expectation of 50%), it will be because of the announcement effect:

A given viewer is well advised to ignore Cramer's advice for what should be perfectly obvious reasons, if people were only educated in skepticism and common sense.

> I agree 90% can't beat the market but I am trying to find the 10% that do beat the market consistently through ArbitrageDude.

I was right. You really don't understand probability. If you succeeded in finding the magic 10%, you would only have isolated a temporary probabilistic anomaly, a "black swan".

Remember that, in science, an untested claim is assumed to be false until incontrovertible evidence proves otherwise (the "null hypothesis"). Your clearly stated position is that an idea is true until proven false -- the opposite of the scientific outlook.

> FT, WSJ, barrons, none of these tabloids provide any accountiblity record of their recommendations.

Your frequent allusion to authority (yours and that of others) tells me that you don't understand science, which rejects all authority, relying instead on direct evidence.
