I beg to differ (not sure if you actually read the Efron talk I just posted). I get the thrust of the Less Wrong article, though I think that frankly his language and vitriol is direly misplaced. He's railing against some class of Frequentists who attack Bayesians. This is sort of a Fox News tactic; pick someone, in this case, a commenter on a blog, and generalize their comment to the entire population. It's fairly unstatistical, if you ask me. I don't get why anyone would do this. A good Frequentist is not a lost idiot, nor does she rail against Bayesians. In fact, a good Frequentist understands the beauty of Bayesian methods, too. I'd even wager that a good Bayesian understands why Frequentist methods have dominated the 20th century.

I'm attempting to realize that rare event in these vitriolic philosophical academic debates - add a bit of middle-groundness. In this case, the middle ground of Empirical Bayes has proven to be very, very useful in large-scale simultaneous inference problems. It's proof that there IS such thing as convergence in this debate. Taking the shrill tone the author takes as a signal of how little regard the two sides have for each other, it's obvious that we need some convergence.
Reddit OP here.

> Nearly impossible. No financial firm is going to pay a 24-year-old that kind of salary, so it's only possible if he got it through bonus. Traders get bonuses based on P&L, usually around 10% if they're senior. Let's say 10%. Then he made 9 figures for his firm... but no firm is going to let a 24-year-old take enough risk to generate a 9-figure P&L.

I agree it's nearly impossible, which is why I make the post. I would like to point out I've been working here longer than my age implies.

> I'm calling bullshit.

A skeptical and reasonable position to have. If I weren't me, I'd also call fake.

> [Update: Well-executed, and he's clearly smart, but his story is incredible. No one hires a 24-year-old to start a desk. This is probably one of XO's finest.]

"Start a desk" really meant I was given a little capital to build out a quant-trading platform and maybe a bit to mess around with. It took a while to get lines and machines set up, set up data collection, etc. After that, the capital and risk limits I was given was on par with other junior traders.

Why didn't they hire an experienced quant trader right off the bat? My firm didn't have the right infrastructure to support quant trading, so any senior person would have asked for a big up-front bonus to be setting this stuff up. Management here was too cheap and risk-averse to pay this. They took the gamble on someone junior and technical.
Clojure is cleaner than CL, but SLIME does not appear to work as well with Clojure as it does with CL. For example, if you have a compiler error, you have to navigate to the location of the error yourself. If you have a runtime error, you get a Java backtrace, that SLIME does not help you with at all (good luck). This is something you should consider, because it will have an effect on your development speed.
The definition that I've found most useful is that introverts get recharged when they are by themselves, whereas extroverts get recharged when they are around people.

This separates a person's interpersonal skills from their intro- or extro-vertedness.

This definition is useful for me because I'm pretty outgoing in "party" situations, but eventually need to spend alone time, recharging, I guess. On the other hand, I have friends who hate to be alone.
What is the opinion on silly comments in submissions that will soon be killed? I've seen people get in one word comments in some of these submissions and not get downvoted.

I have had some fun myself. My latest: "Opening studiobriefing.net was like watching time lapse photography of some butt-ugly flower blooming."

These are the only times that I knowingly type something that I know has a good chance of getting downvoted. But I will stop if you guys tell me it is a bigger deal than I think it is. I just don't see the harm in commenting something silly into a submission that will likely get killed.

Please correct me if this is at all detrimental to the community.
I agree wholeheartedly. The first thing I noticed with Bespin specifically that STILL hasn't been fixed as far as I can tell from using it for the last few minutes was the lack of auto indentation. It is such an important thing for a code editor. It HAS to be there.

EDIT: I see they added the autoindent setting last March. I still can't for the life of me figure out how to actually enable it. It should be on by default, no question about it.
Both Clojure and CL can do those basic things, now which one do you know best?

This feature-based language choice is meaningless if you're not taking your own strength into consideration.
Argh. Reminds me for some reason of the stand-up comedy formula. You are correct. I forgot the punchline. The ellipsis.

Example from Robin Williams

"Parenting is hard" (Premise)

"Once you become a parent, you have responsibilities" (Statement/setup building on premise)

"For example, you can't go out drinking, come home drunk, go up to Junior's room at 3am and say 'For a change, Daddy's going to throw up on you now just like you do" (Turn around, the twist)
Ah, I've learned something. I always thought "Evangelicals" were simply Christians (or indeed, others) who practised Evangelism. However, from what you say a particular sub-class of Christians have decided to take the name and make it their own. That makes sense, and matches what I've now double-checked.

Thank you. I'll read some more to avoid any further confusions.
That's what I've always heard as well. I think this might be a useful reference as well:

In terms of a test, the MBTI (http://en.wikipedia.org/wiki/Myers-Briggs_Type_Indicator) is pretty good IMO.
> Of course, but bonus is based on P&L, and no one's going to give a 24-year-old enough trading freedom to run up the kind of profit that would justify an 8-figure bonus.

My risk limits and capital have been increasing that allow this. Previous years were much lower.

> Starting a hedge fund is different-- if you start a hedge fund, you can make that kind of money-- but <0.001% of people under 30 have the kind of connections needed to get investors.

Actually, it's not that different. The labor market is reasonably efficient. If your employer thinks you can run off somewhere else with a low barrier-to-entry (another fund or start your own) and can make 10 times as much, they'll up their pay to prevent you from leaving.

Of course, non-compete agreements throw a wrench into the "efficicent labor market" theory, but it's correct to a first approximation.
Times are tough :/
I like the tech and industry related business posts only. There are other forums for other things. Case in point, the one or two posts linked to stories from the New York Times that seems to show up every day. While I’m sure there is a subset of us who enjoy reading the articles in the New York Times those who do are probably already reading it natively and don’t re-read them in this forum.

I realize the NYT is linked on the main page of the YC main site, but the two posts that seem to show up every day strikes me as being spam in a tech forum. They are not on topic. Same with the climate change conundrum posts, there are other forums that discuss that on a daily basis such as http://www.abovetopsecret.com/ .

If this is a vote type of thing I would vote for tech and industry related business posts only. That is what makes us special and unique as a forum.
I think you're on to something regarding "significance." Over in my dept. we like to say that significance is a measure of sample size. The question, then, hinges on whether or not something has practical significance. Because we've built the whole research reputation incentive structure on the .05 significance level, studies can be designed to get that.

A great article on the problem with statistical significance (by a Frequentist) is here, called Why Most Published Research Findings Are False:
http://www.plosmedicine.org/article/info:doi/10.1371/journal...

The punchline seems to be, well, that there's also a large human element that contributes to the problem. I think it's one thing to rail on the Frequentist way-of-thinking; it's entirely another to state that the institution of scientific research built on it creates unwanted incentives.
Ryan Bates' Railscasts (http://railscasts.com/) are uniformly excellent short introductions to different topics, and a great example of how to do screencasts right. They're short, give a quick overview of a new and relevant topic, and you can pick up a lot of little tips and tricks on how to develop in general as you watch him code (especially if you use the same tools).

They're a great way to get jumpstarted on something you've never approached, after which you're in the right frame of mind to jump into the docs, since you will have grokked the general overview of the topic from Ryan's short summary. YMMV, but I find it much easier to get an overview quickly than hitting a pile of docs cold.

> I call bullshit.

Reasonable. Mine is a highly unlikely story.

> He says he is 24 and at a well known quant fund. I know a few people who work at some of these places and at 24 you simply would not get the risk allocation to be making 8 figures.

We're not a well-known quant fund. In the hedge-fund circles, we're known for non-quant trading, but not especially as a quant shop.

> On the other hand, if he was managing capital himself, on his own, anything is possible. But it does not seem this way from what he has said.

I'm not managing my own capital, it's the fund's capital. That said, they do pay me enough that I don't want to run off and try to start managing my own.
"Fact" doesn't mean p==1 (an unreachable goal) it means p approximates 1, less some insignificant minuscule slice of the pie within which live all the mad implausibilities you might think up - but which Occam's razor forbids.

VCs are market makers; they facilitate their LPs investing into their portfolio companies. Brand is applied in two directions; upstream to their LPs (who are upstream of them in the capital supply chain) and to prospective investment opportunities (who are downstream of them in the capital supply chain).

From Upstream: Yes, brand matters. Having good returns is important. Many LPs also have LPs themselves; being an investor in a good fund makes explaining things that much easier. The "Nobody got fired for buying IBM," issue exists everywhere in capital supply chains. Dozens of LPs enjoy casually dropping, "We invested in Google."

For Downstream: VCs manufacture capital returns for their investors. They source inputs, private companies, in which they invest, oversee operations, and assist in the creation of exits. Having a lower cost of private company acquisitions is similar to any manufacturer who has a lower COGs, or an IT group who is able to design and build more efficiently. So, yes, brand matters there too.

In a community that has experience with VCs, brand matters less, just as it matters less in any community that is more focused on results rather than karma. The role of brands in VC, regardless of the directionality in which it is being evaluated, is similar to any other marketplace. The complexity comes in realizing that brand flows in two directions.

I wrote a longer comment on upstream / downstream capital flows here: [http://web.mac.com/flybrand/fredlybrand/Blog/Entries/2008/9/...]
Personally the best case I can see for wave is that some of the features get absorbed into GMail. I can't see it succeeding on its own.

(I just tried it out for the first time). Horrible bloated slow UI, hideous scrollbars, and pretty underwhelming.

It didn't seem to solve any problems I had.

So thinking about real useful features people want, how about they add a 'collaborate on email' mode in gmail, where you can write etherpad style email drafts with other people and when you're all happy, click send. I'd rather they work on things people want like that.
Two examples I can think of:

The dictionary implementation of Python is a hash table using open addressing with quadratic probing. Deletion is essentially a lookup to replace the key with a tombstone. And, the table is never resized after a deletion.

So yes, the whole operation is O(1) on average.

The technology isn't hard. I know 'real time' is ridiculously over hyped now, but it's not rocket science. I'd expect quite a few etherpad clones to popup.

I am curious, wasn't AppJet JVM based (using Rhino for Javascript)? Why couldn't they offer support for Ruby via JRuby? Would have been a language that's both much more pleasant to work than PHP and has great traction with web developer community. Was there a switch away from JVM/Rhino to a C/V8 based solution?
Given enough money, I would be excited by drying paint.

DARPA Network Challenge (find the red balloons) is live
i can recall two 'erlang days' so far.

the first happened when pg said the site was having some trouble coping with an influx of new users due to some high-profile mentions on other sites. he suggested posting articles about erlang to make the site look boring. i guess people complied a little more than he was expecting, so then he asked people to stop.

the second time was when the site was overrun with articles about _why, right after his disappearance. some people thought it was a little too much, which once again triggered an influx of erlang articles. it looked to me like pg and the editors started killing erlang articles after that, and possibly the _why articles as well.

Large Scandinavian Study: No link between mobiles and brain cancer
I find your statement unfair. You're assuming/implying he's asking for a free product; he's asking for the courtesy of a warning.

1. Nobody's claiming entitlement. If there was entitlement there would be recourse. Asking for warning isn't entitlement.

2. You're implying that he wasn't looking to pay. He's said he would pay if he had warning.

3. You claim he 'depended' on it. I'm not sure that's the case. Not having warning is inconvenient, not catastrophic.

4. The company got its valuation in part from people who didn't pay. I think that entitles them to basic courtesies at least.

5. Companies do good by non-paying customers all the time because they care about goodwill. Google and Etherpad have lost some goodwill here by going against consumer expectations.

Basic courtesies aren't paid for and aren't bought. That's why they're courtesies.

An egoist is a person who is concerned with how good they are. Whether they're an introvert or extravert would only define where they project that feeling.

For instance, an egoist introvert would likely spend all day thinking about how good they are to themselves. An egoist extravert would spend all day telling everyone else how good they are.
Even as an introvert, I think that extroverts can sometimes come to the same well-planned decisions through more of a conversational process, deliberating out loud and with the help of others.

But the title and point of the article are simply why introverts can make good leaders, not necessarily why extroverts aren't just as good.
That doesn't really matter. the important thing is the information from others, which the people on hacker news are likely to be good at gathering. Of course more fun might be preventing everyone else from getting it...

My people (the Germans) have this reputation for being impolite. I tend to think this is because we have the tendecy to be brutally direct when we want to be honest. We like to be honest, in that sense anyway, regarding matters of work. This comes off as rude to members of the civilized world (say, the British or Japanese). (I am writing this after +6 years of experience living in foreign countries.)

Another observation: the heroism around doing ones work is strong in Germany, we have that in common with the Americans (in the West, don't ask certain Asians). Yes, certainly there are many French (for instance) fellows, who like theire work. But the Germans (and Americans) have that tendency to get "macho" about it.
Parenscript excels at combining high-level abstraction with runtime efficiency in a web browser. It has to do with Javascript, not HTML, and if you've used it as much as you say, you know that perfectly well. Arguing that PS sucks for web apps because web designers don't know Lisp could hardly be more of a red herring.
"They also use their calm, quiet demeanors to be heard amid all the organizational noise and chatter. (One thoughtful, reasoned comment in a meeting can move a group forward by leaps and bounds.)"

I ran this against my ISP's DNS as cached by my router, Google's new 8.8.8.8, Level3's 4.2.2.1 and 4.2.2.2, and OpenDNS.

It performed 200 tests in 1 run, using my 100,000 Firefox bookmarks as its data source in 'weighted' mode.

My results were as follows:
"In this test, Your current primary DNS server [my router's cache of Comcast's DNS] is
29% Faster than Google Public DNS".

I am in Boston. In ranked order of performance:
My router's cache of Comcast (48.28ms),
Google's 8.8.8.8 (62.49ms),
OpenDNS (68.14ms),
Level3's 4.2.2.1 (94.37ms),
Level3's 4.2.2.2 (113.51ms)

*Update - I clarified that I tested my router's cache of Comcast's DNS, not Comcast's DNS servers themselves.
Neat-o. This would be an appropriate platform for a time-delay repeating or remote-controlled TV-B-Gone. I've thought about how I could mod my original TV-B-Gone to do that.

I really like my TV-B-Gone. I've given several of them as birthday presents to the children of friends. They appeal to the ten-year-old boy sense of mischievousness while subtly conveying the idea that mindless television is a bad thing.
To the extent that introvert and extrovert, as unfalsifiable subjective descriptions, really mean anything anyway, it has nothing to do with listening to people speak.

Listening is simply a conversational skill and has nothing to do with meyers-briggs personality type. Some people are naturally better at listening and others aren't. Some people practice and gain skill others do not.

Thoughts on my site ?
So I just finished the first alpha version of an idea I had. Let me know what you all think of it, or have any suggestions, questions, comments.

Here is the description of the site:

PushTruth.com is a real-time content site that allows users to post articles, pictures, video and music. Users can vote on the items submitted and see hot stories grow in real-time, or unpopular stories strink. Users can also zoom in & out to view smaller items. Stories can be posted in the future also (eg: a press conference to be released on YouTube 2 days from now). Users are also able to drag the main interface as well.
Maybe I'm not in the target audience, but I find the article incredibly confusing. Parts of it literally feel like something out of SCIgen.
Is there a good test? If by "good" you mean "scientific" then the answer is certainly no. There are tests where you answer questions about how you think about various different kinds of real-life scenarios and will assign you to one or the other. The tests use casual and vague definitions and the label is assigned based on entirely subjective self-measurements.

"Do you enjoy being the center of attention?"

Since everyone shares traits of introverts and extraverts, it's easy to take a test and read the vague description they give you and think "oh yeah that sounds like me."
Overengineer much? The current system works.
Are you referring to reverse-auction programming sites? There's plenty of those to be found.

I do not have a favorable opinion of most of them, and that's because they list the bid amount and bid text. It ends up becoming a race to undercut each other, to the point where I have seen a prject with a $10 USD bid that would take me 10 hours.

I frequent Guru.com to pick up small side projects here and there. It does not list the bid amounts, lists the country of origin (for both employers and freelancers), and uses an escrow service.
