I call hoax on these drawings.

Look at them and notice how every drawing focuses heavily on the buttons on the shirts and coats. Plus the body sizes are very similar from drawing to drawing. This seems outside the level of probability for a sample of drawings this small. I highly suspect that all of the drawings were drawn by one adult trying to make it look like students drew them.
No, I wouldn't say pricing is fundamentally an infrequent activity, although analyzing the "idiosyncratic risk" may well be. That's not all that's going on though. For example, investors in, say AAPL, do not live in a Plato's cave where nothing else but Steve Jobs' latest keynote matters (believe it or not!). There's the rest of the market to consider.

In fact, a lot of algorithmic trading is about quickly assessing the value of a company in the context of a larger portfolio. If you accept that the market index can (and should) fluctuate second by second as the world tuns and news gets reported, then you must accept that companies' stocks will be traded alongside it (usually in rough proportion to the amount of liquidity available).

Here's how that can work. If you're comparing two stocks that share fundmental drivers, then you can make "pair trades" when they fall out of correlation. If Pepsi (PEP) does really well one day and CocaCola (KO) does terribly for no apparent reason, then it may be a good trade to buy KO and sell PEP on the supposition that the stocks have moved out of equilibrium.

This is basic arbitrage, and if you extend the practice across all the traded securities you'll find you need some pretty serious computing power. I suspect this accounts for much of the silicon in the basements of banks and hedge funds.

Notice that I'm just talking about the pricing function here. You can price a stock all day long and not have to trade on it.

And I'll agree that there's way too much volume, churn, and speculation in the market. I'm not sure, but I feel like it's becoming more and more a behavioral system. I wish people and institutions would better understand long-term risk and the costs of commissions and slippage when making investments. If "managed" funds became a dirty word, there may be a lot less volatility in the market.
> [Most] High frequency trading and "investing" are basically the same thing on different timescales.

Yes, it's basically the same if you take out all the differences. Nothing said so far.

Also, investing is clearly not the only activity on markets (speculation, arbitrage, you name it), so let's not over simplify things.

Interesting reflection field, though.
There are a lot of things you can do with $250K that you can't with $115K. For instance, after two years you qualify as an accredited investor and could form your own hedge fund or seed fund.
No, this is a very honest question which has been lurking my mind for a while. Sorry, if I had worded it badly. Its not like money is my only motivation. I definitely do want to things I enjoy (coding/math/statistics/entrepreneurship) or at least as close to it as possible. I would never compromise that. But to answer your question "what can you do with $250k that you can't do with $115k?" -- I have thought about this for a long time. In fact I use this argument to suppress my dissatisfaction of not making enough money. I guess I'm not a content person when it comes to money and I guess I feel it is a measure of career progress and that I'm moving forward rather than being stagnant. Of course I would be kidding myself, if I say its the only measure of progress, there is always the value produced for obtaining that money.
About four months ago I had a client who received their licensing information put in a claim on me. Even though I sent full documentation showing that they received their license they still refunded this individual. That did get me quite upset with PayPal. Since then I really haven't done that many transactions with them or any online freelancing. I'll have to keep the wire transfer in mind for the future. Thank you bosch!
Your code sample isn't quite right.

[read stdin] returns a string (not a list of strings), which is parsed as a list when you try to loop over it. The parsing breaks the string into a list of words, so the second loop is redundant. The parsing could fail if the input file isn't valid list syntax (unmatching {}'s). [split _] makes it safe.

foreach word [split [read stdin]] {
if [string match *ing $word] { puts $word }}

I love Tcl too! Tcl is a scripting language for C, Python is less-powerful version of Lisp.
When It Comes To Founding Successful Startups, Old Guys Rule
@twobraids on Twitter lives in a minimalist self-built yurt. It's been a while and I am on an iPad, but he has a website detailing the build.

I did research on these tiny houses a couple years back and they have a nice variety of builds. Some of the ones with sleeping lofts were very interesting.
How the brief was written scared me a little, but 37Signals charges a pretty decent amount to post a listing so I figured it was all going to be kosher.

So, the question here is: why didn't you trust your gut feeling? Why did you value your (simplistic) rationalization more?
I hate to be the bearer of bad news but, based on the comments you've made in your post, you are most likely a smart fool (as you have so aptly put). In essence, you don't even know what you do not know.
I've worked at top-tier Wall St institutions and have had first hand experience working with several of the largest quant hedge funds out there.
Here's my advice: if you truly enjoy markets and are sure you want to take this path, you will be much better served by spending several years working at an established quant hedge fund. This will open your eyes to the theory, processes, data, and techniques required to earn alpha consistently and in a risk efficient manner. It's a long road and that road is full of extraordinarily hard working and intelligent people that one has to constantly compete against. If you can handle this though, you will learn a bunch and at some point in the future you can strike out on your own again. At that point you will at least have a chance of success.
Good luck!
None of the major codec players promise to shield from or take responsibility for infringement, at least not for normal licenses. Not MPEG-LA, not Microsoft, not IEEE, not Google, not Fraunhofer.
I can't speak for him but it's probably the part where the guy insisted on a payment method that he could back out of after receiving the final product and wouldn't accept two reasonable options that he was less likely to be able to back out of.
I believe you've misread the license. Google is granting a license to all patents they own or will acquire in the future, required for VP8 as they released it.

If you modify your own version of VP8 so it infringes some other patent that wasn't infringed by the original, you don't automatically get a license for that other patent. In other words, you can freely make VP8 implementations without worrying about Google's VP8 patents, but you can't write your own patent license for any Google-owned patent you want by writing that patent into your own version of VP8.
Ok, now that I get it, that is a very funny name. (Perhaps even up there with Rinda!) I'm glad I don't have to use it, though.
My name is Ari and I'm a senior software engineer at Palantir. I was the second member of the Palantir Government backend team so I've been with the company almost five years. I've seen this place grow up around me. To describe me a bullish about this place would be an understatement.

I can categorically confirm that this is not BS: we don't have sales people, we don't have marketing people. This doesn't mean that we don't have people performing those functions -- of course we do! However, the people performing those functions are all technical folk who have stepped into the breach to do the needed work to grow our business. As a commenter in the TechCrunch article mentioned, "I'm the founder at my startup. Just because I sweep the floor sometime doesn't mean I'm the janitor."

I think what we said got a little garbled as it was distilled into the TechCrunch article. When we said, "we have no sales people", what was meant was that we don't have people who know nothing about the product, worrying about their commission and their quota and adding essentially zero value to the process. The people who come up with our marketing messages are not people with marketing degrees -- they're engineers who intimately understand our technology and the benefits that it brings to our customers.

Even I've stepped up into that role: along with writing our backend data importer and authoring our XML formats and processing pipelines, I also run our college recruiting program, and write for and edit our tech blog . Does that make me a recruiter or a blogger? Not in the sense of the word that most people would use it. I'm an engineer, proud of it and my technical achievements, and anyone who calls me otherwise better do it when I can't hear them. I'm an engineer that does recruiting and blogging, just like we have other engineers that do sales and marketing.

I look back over my time here and I marvel at the amazing place that we've built. It's an engineer's fantasy land that really exists - I can only think that this is what Google was like, circa 2000.

But don't just take my word for it, come and check us out for yourself. Shoot me an email to ari@palantir.com and I'll set up a visit, a proper interview, or whatever is appropriate for your situation.
Yes, the Nexus One is a great choice for the parameters you listed. It's a powerful phone with a lot of life and it will likely get Android updates rather quickly as it's a "Google" phone.

Your only choice for pay as you go will essentially be T-Mobile. Forget the Incredible, it's a great phone but it doesn't meet your second criteria.

Seemed odd to me too. That would have been one I skipped right over
Reading your responses below it sounds like you want to work on interesting problems that have a quick turnaround in terms of real-life implementation.

I'm in a similar situation and I'm looking into doing a graduate degree in Operations Research (OR) or Industrial Engineering, which is usually offered either in Business schools or Engineering schools. You essentially do research on solving real-world problems with quantitative methods.

Many of the OR graduates (even those with PhD's) end up not in academia but in business. If you have more questions feel free to email me.
XBox has cost MS an enormous amount of money and they haven't recouped much of it as yet.

By late 2006, MS had already lost $4 billion to the XBox project 2 years later this was out to $7 billion. I think recently they've been turning a profit of about $200 million+/quarter
As I commented before I think it is a bit of me still trying to give everyone a chance. From the brief it did seem like that something was off. I just have to keep developing on letting certain "opportunities" pass at certain times.
The thing is in case of tracing you don't record all paths taken, just the one at the hot point. So say you have if that takes every path every second go, the JIT will compile just one path at first. Then the guard will fail every second iteration, hence the blackhole. Of course at some point JIT will realize guard fails often enough and will compile another path, so you'll get a tree. And so on...
That's sufficiently not true as to be completely false.
The job ad was riddled with typos, bad grammar and bad style. Why did you even respond to it? The domain name on the email account was different from the name of the company. The person running this "Shivum Gautama" has zero history in google. etc.

Overall, Mr. Gautama might have been a creep but atleast he was decent enough to show his true colors so early in the game.
I have this happen to me. My licensing system accepts the PayPal Reversal IPN and cancels the license key. The next time the software checks for an update it sees the license is invalid and disables the license. I'm not sure if it's the best way to handle the situation, but it's effective.
You really should consider releasing your work. It's a great motivator to do more and release often.
Obviously the posting is still up. Have you emailed the transcript along to the folks at 37Signals? They should really pull this (or better yet append the transcript to the job posting).

Knuth will make an Earthshaking Announcement on June 30
An interesting option is MBA-PhD in OR from Stern NYU. Which is something i am seriously considering. I have looked at a profile of a guy there who did MS CS. Worked for topcoder or did research about it. And now studies in Stern. This could be the golden mean which i seem to be looking for.
The B52 is better than nothing.

I've encountered several interesting languages over the years and they would all have been really nice and painless to use only if it wasn't for their lack of standard libraries that are just there.

Good set of standard tools and libraries are more important for a language's success than the language itself. The language has to be quite bad in order to drive programmers away from good libraries.

It's the Python problem: I know the shortcomings of Python quite well and I would happily use some other language instead except that Python has almost everything and despite the shortcomings of the language itself, Python is by far the fastest way to code a quick program to solve some random, particular problem.

I don't like Java but in the case of Clojure, the heavy machinery in JRE is a critical life-saver. Sure the Java side is ugly but at least it's there for Clojure.

The world is full of lisps that you can't do anything with. Clojure isn't one of them.

http://news.ycombinator.com/item?id=1467116

To quote that guy
"""

Thanks for the advice. I'll definitely listen to the Merlin Mann/John Gruber talk. I agree that money doesn't come without producing value first. I guess I was just a confused engineer frustrated at the slow growth rate rather than thinking about the value I can produce.

I am realizing the same thing before and trying to design an appropriate career path.
This is why I always prefer to look them in the eye and ask for a face to face meeting. If that's not possible, then I'll do a Skype video conference. That's not going to weed out all the crazies, but at least it'll give you a better feeling to complement your initial guy instinct.
Since current 3D TVs also make decent 2D TVs, I don't think it'll be such a bad thing. If you're only interested in 2D, you could theoretically pass double-rate video marked as 3D, and get a 120Hz refresh rate. I don't know how HDMI 1.4 signals 3D vs 2D video, though, so you may need a video card (or dongle) that can send the right signal and/or flip the right bits in the HDMI signal.

Snapshots from a GSM Workshop
Saying no can be really, really tough - but rewarding. In my experience most programmers are conflict-adverse and like taking on projects, this might be obvious but it means we often find ourselves over stretched. Speaking of 37signals, David had a good post on that awhile ago (http://37signals.com/svn/posts/1626). It's a real problem that I, and I'm sure many others here, struggle with.

edit: (unrelated) Have you brought this to the attention of 37signals? You should send them this story, I feel like they may want to keep unsavoury characters like this away from their board in the future.
This reminded me of something the other way around.

Back in 1998, I was on summer break before going to college. My parents said I had to get a summer job, so I got an entry level PR job at a Web design agency (new media, baby!) in London. Somehow, within a few weeks I was attending recruitment interviews. One totally normal looking guy came in, sat down, and after a quick introduction the CEO asked him what his background was. The guy jumped up, shouted "you can go f!@k yourselves!!" and ran out slamming the door. Never saw him again.

I was only at the agency a month in the end, but just the crazy things I saw there could fill a book. In hindsight, I regret quitting.
Is anyone making Adwords convert these days? I haven't.

since H.264 (the current industry standard video codec) and VP8 are highly similar, we can share code

Hopefully not too much similar (or defeats the whole patent dodge) !
> I wouldn't be surprised if the eventual winning business model looks more like a Walgreens and less like Starbucks.

Hmm, I was thinking the opposite. A fancier more "treat"-like atmosphere with higher prices and more exotic products would help to differentiate.

I guess both probably have a market.
You're absolutely right.

I don't think that Clojure isn't meant to be an easy language for newbies, like Java. Clojure is a master's tool, like Unix. Good tools require time to learn and for the user to develop a bond with them.

It's precisely the functional programming, multimethods, immutability, concurrency, macros, and sexprs that make up Clojure's value. There are enough blubs already.
A Facebook-killer. So, what's next? the Zune? ;)
Yes, I have contacted the guys at 37Signals. They said they would be in touch with the creator of the listing to verify all of the details.
Nothing pisses me off more than those protesters who wear all black and cause violence and destruction. Until those types of protesters are stopped, police will not be taking chances, let alone with someone who is uncredentialed.

I disagreed with the $1 Billion dollar price tag for security for the conference. However, the actions of those in black make it quite apparent that some people do not know how to protest peacefully and ruin it for everyone else.

I liken it to Islam and the fact that a few suicide bomber fanatics make people think all of Islamics are crazy.
That's pretty ridiculous. The body sizes and visual similarities between students are not as close as you make it sound, I could easily see this set of drawings coming from one of my classes in seventh grade.

Why not go with the much simpler and much more likely explanation that the before and after pictures and descriptions all have similar content because the teacher held discussions before the students drew the pictures, and these discussions were lead in a certain direction.
More than syntax, I think the bigger issue is "thinking in clojure".
There have been far too many tutorials about Clojure-for-Ruby-users, etc etc.

But the problem is that clojure _strongly_ eschews object-oriented programming. But ActiveRecord and Django ORM are (or pretend to be) object-oriented.
Therefore, there is a strong mismatch conceptually (e.g. http://stackoverflow.com/questions/3067261/how-does-one-mode...).

More than an IDE, there is a strong need to migrate _thinking_ from Rails/Django, etc. to Clojure.

Ask HN:  Denver area guys with web app/community building experience?
I'm a 25 y/o freelance designer in Denver looking for somebody in Denver (+ surr. area) to build out a back end for a concept I'm working on. Aside from HTML/CSS/Javascript I'm pretty green, and need a developer on my team immediately.

This would be a conglomeration of a typical forum style community with some added features to push the money making features of the community. It will ad-supported, but I imagine (hope) that will be a fraction of what the site generates itself.

The ideal person will have experience with Colorado Amendment 20 related activities.

If you're interested, shoot me an email at jd@imperial.org with any relevant experience (web apps, web community development, etc) -- I'm looking to meet up with somebody as soon as possible and get this moving. Thanks.
It's Japan - so having a bath is an important feature, which I do. In fact, I think it would be pretty rare to find a place with just a shower. It's kind of a bath shower/combo, as is typical of Japanese homes and looks something like this:
http://media-cdn.tripadvisor.com/media/photo-s/01/16/27/30/t...

In here, the bath is covered as Japanese usually share the same bath water amongst the family (you wash in the shower before getting in - it's more about relaxation than cleaning).

That being said, I never use my bath.
"attacked" is hardly the proper word IMO. Scared off is a better term I think. Not surprisingly though, there is of course much more to this than meets the eye:

I commuted to Google for 4 years. Even with the bus it was tough. I was the same though, living in the valley is not really an option, and I'm glad I didn't.

Some advice:

- live as close as possible to the highway or caltrain. this means soma, potrero, the mission, or noe valley.

- negotiate at least 1 work from home day. friday is the best. (although wednesdays are usually easiest to ask for first)

- work off peak.

It's possible to get your average commute to about 45 minutes, which isn't so bad (still gets old though).
A short answer would be: one of the externalities that traders like the OP provide is lowering transaction costs for other traders such as investors. Compare trading stocks with speculating in real estate: buying a $150k house and selling it later might involve (say) $10k worth of commissions to your real estate agent, while trading fees on a comparable stock transaction are usually much lower.

Please see my other comment below and (especially) the linked article.

http://news.ycombinator.com/item?id=1467171

Another positive externality of trading is lowering the cost of funding for enterprises. Companies go through a lot of trouble to make an IPO; they do so because getting listed increases their sources of funding.

A longer answer would probably require a blog post, so that we could discuss whether I'm "cheating" -- after all don't the points above boil down to providing liquidity? Am I really "cheating" or maybe your condition is unreasonable? Et cetera. If I write such a post I'll post it to HN, though I doubt I could do better than Larry Harris.
