They wouldn't even need to trade securities. Just search the future data for some successful tech IPOs and then invest in those companies early and heavily. Returns would be fantastic, and the risk of feedback from your future-influenced actions would be much lower.
What is the value of an aggregated price per room across all apartment sizes? A 1 room apartment is going to cost more than half of a 2 room apartment, which is going to cost more than one third of a 3 room apartment.

The price per room seems like it would be more useful if it was shown as "price per room for 1bdrm" and able to be switched to 2bdrm or 3bdrm and so on.
Yes, but they have strong motivation not to abuse it. I've seen one case where an news org broke an embargo due to fat fingering a release, that news org lost early access privileges for a year as did every sister company that belonged to the same news group.

If you specialize in financial news losing numbers is a huge deal, you'll lose thousands of customers over it. And when those customers are often $1000/month subscribers it can easily mean a financial loss of tens of millions of dollars.

Within news organizations the information is typically restricted to 1-2 named individuals who have restrictions on trading. If they leak the information they can generally be criminally prosecuted.

All companies litigate, what does that have to do with speculation on future product details? It's also a pretty weak reason alone to change buying behaviors if you previous were a consumer of Apple products (their corporate tactics are not new).

If you have the icons as svg you could also try raphaeljs [1][2]. It'll render the svg path as svg on most modern browsers and as vml on older IE browsers (ie6+). The added benefit is that raphael also does animations which enables you to animate your icons on browsers that don't support css3 animation.

To some extent I agree with you, but it is a slippery slope. If we always deny that one person really is a problem, we may retain a truly bad employee while building excessive safeguards that hinder productivity for others. In my experience this possibility is all too real.

A team of good people should learn from their mistakes and reduce hazards along the way. But bumper bowling is no fun for experienced players. It's a balance, and it does tend to shift as a company grows.
I don't think api was criticizing Bitcoin. All these evil activities are very unfortunate, but on the other hand they are indicators that a currency is valued and liquid, which is a good thing in itself.

It's funny how there are a lot of expressions with the word 'dutch' in it with a negative connotation. I'm Dutch, and I can't think of any expression with the word 'Engels' in it, both with positive or negative connotation.

Talking To People You Don't Know
Way to make sweeping statements. Waging war is always highly unethical?
I wouldn't be able to view it so black-and-white. For example, what about waging war for independence against a tyrant or waging a war to prevent genocide? What is considered highly unethical is also highly subjective.
You should make this a poll so people can vote on it. I sleep at 10 pm and wake up at 2am and 6am to feed the baby, then 6:30am I leave for work.
Seeing as how Bootstrap fails at even the most elementary of tasks (using absolute instead of relative values for positioning, for example, screws everything up when the user's zoom is anything other than 100%, among many, many, many other flaws), anybody who uses this framework is a competitor I am... not worried about.

On 3, I think it depends on your time-travel rules. Because the first thing that would happen is that people would flock to retool to produce the higher value commodities (if corn price > wheat price, people would stop making wheat and start making corn), causing a supply glut and price collapse.
"I wonder if there's a spread between IV in UNG options and in the futures market to do a calendar or ratio spread."

UNG is implemented via futures. They announce roll dates every month http://www.unitedstatesnaturalgasfund.com/ung-rolldates.php and the futures traders definitely arb the fund's roll.
Consider doing exercise that strains your bones and strengthens you in ways that will protect you when falling. Jiu-jitus is excellent at this.

I can't!! I need to have more karmas to create a pool (i.e., 200 karmas).
It won't. High frequency trading slices the gap between offer and purchase into an enormous number of tiny slices, and HFT companies compete to see who can collect the most number of slices. But that does not affect the underlying factors that lead to most offers and purchases of stock.

For example you could offer OJ futures at improperly high prices a billion times per second, but that does not mean anyone will buy them. I'm not aware of any evidence that Amazon's weird million-dollar books have affected the price of popular new books.

In addition, I wonder by what criteria one would evaluate how "properly" the markets are functioning. Who decides what is proper? For example, based on the business fundamentals it seems ludicrous to me that Apple would have a lower P/E ratio than GM--but it currently does.
To elaborate a bit: I'm trying to judge whether this is a good project to keep working on or not. Any interest in a Mac App that works as a front end for Mturk's Requester interface?
My intention was to point out a current difficulty with digital files, which is that they are legally stuck half way between property and license. You used the word property as if it was assumed, which struck me as odd, because to me they don't feel like property.

My comment was trying to point out that if we really tried to view digital files as property we get into problematic territory. For example: http://www.bbc.co.uk/news/technology-19842851

A lot of the language around digital rights issues seems to me to be loaded. The use of theft to refer to copyright or even the words Intellectual Property, begs the question of an argument not yet proven. Eg http://en.wikipedia.org/wiki/Criticism_of_Intellectual_Prope...
There's also a very significant risk of injury involved with chiropractic procedures, especially when spinal injuries are involved.
That's exactly right. I'd wager that millions of people have bought from Amazon but no other online store. And I doubt any other online store selling physical goods in the US can beat them by that metric. It's not that people won't shop elsewhere but that they literally are unprepared to let themselves do so. One-click shopping is a great idea to keep grandma loyal to the store, because her son probably set it up, and he's not home now.

I've been wondering if an exchange that prevented HFT would prosper in the current climate. I'm sure that plenty of companies aren't a fan of their market cap being at the whim of an algorithm and the large number of swings it would undergo.

Wouldn't they prefer an exchange that offered liquidity in minutes or even hours, opposed to fractions of a second?
Btw, I noticed that Diamond has another book out, for all of you who are interested in his work.
Ah, thanks for the info - need to learn my history a bit better.

My point still stands, I think that by the time Django made it out into the world Rails was already established as the dominant framework. Django 0.96 hadn't been as thoroughly thrashed as Rails and definitely had the warts to prove it.

Django is a much more mature beast these days, though I still lean more towards Flask if there's a choice to be made.
You're not exactly setting a high bar for meaningful discussion.
This feels very polished. Fantastic work. How did you implement this? Is this done using RenderScript and standard layout elements or some OpenGL/gaming library?
"interruptions were greater in number but shorter in duration and more on-task"

Given recent studies on multitasking, and the time it takes to get back on task, this does not sound like a positive thing.

"an ability to share work artefacts significantly challenge the effective collaboration of remote stakeholders"

Most "work artefacts' in software development are digital (and easily shared with the modern internet), and thus distance doesn't matter. This is obviously different from when this study was published in 2002.

The delay mentioned in the 2001 ieee article is virtually non-existant in modern work-from-home settings, where people are constantly connected by DVCS, screen sharing, skype, google hangouts, etc.

Yes, I'm cherry-picking problem quotes from your cherry-picked quotes, and don't have any studies to back up my beliefs (other than my own experience, which is frankly enough for me). That said, most of your citations are old, don't take into account research into human multi-tasking on complex projects, and don't take into account the tremendous advancements in remote communication that didn't exist as little as 5 years ago (github, google+, skype group calls, Trello, Bitbucket, Facetime, etc.)

Yet another anecdote: the last open office I applied to was definitely a war room... Warmachines, that is. I can't imagine getting anything of value done in that kind of environment.

Your use of "the really hard problems" is revealing. Those of us who went to engineering school know exactly what you mean by that, because it's the way we describe the most challenging exam questions, projects, or open questions in the field. We can usually figure out those really hard problems if we put our minds to it.

But for most tech startups, I'm not sure "the really hard problems" are the technical ones, because we are good at technical problems. Perhaps the really hard problems are how to get early traction, how to build something people love, and how to make the business profitable. Some of those hard problems might be easier to solve as a face-to-face team.
You seem to have forgotten to quote the next paragraph which says, "In seriousness, it looks like a nice language -- I wonder if it, or the Ruby, Python, JavaScript "front-end" toolsets, might be a better fit for extending Erlang applications to programmers who are looking for a kinder, gentler syntax?"

Right. I'm upvoting you because I agree with you, however there's a BUT coming...

Buuuuut I think this is one of those situations where cause/effect is a little muddied. As a founder you push yourself to an extreme.

However when there's a world where the investors can place their money where they like

...and they fetishize and laud the founders who work to extremes

...where the stories of success involve near bankruptcies, second mortgages, maxed out credit cards, relationship difficulties and these things are seen as a mark of effort

...and where they pattern match to rather crazy degrees to cut through the stupid numbers of pitches they have to mine through to find a winner...

then what seems to happen is that founders internalize that if you aren't making those huge sacricfices you just cannot compete.

It'd be like the Tour De France, or steroids-era baseball. So long as the rewards are going to those who cheat and risk their lives with dangerous drugs, there's a perverse incentive for even elite athletes to cheat and take the same risks. Is it a choice? Sure. But it's sort of the only choice.
I read this morning in Nate Silver's new book (recommended by Fred Wilson and published September 2012) "The Signal and the Noise" that the average time a stock was held was 6 years a few decades ago, recently the average is closer to 6 months.
Look, 42Floors is going to succeed not because their problem domain is the most interesting, or because their code is the prettiest around. The reason 42Floors is going to be successful is because of Jason's hiring practices and the entrepreneurial spirit of the staff.

If you read the hiring alerts that hit HN, the 42Floors are very well written, inspiring and they give a strong feel of the company culture. I admire this business a lot and I can't wait to see what they accomplish.

Keep rocking in the free world, and congratulations on securing additional funding.

Indie dev makes game about his s***** day job, gets fired
I have worked both on a hybrid team (colo + remote) & a completely remote team (no office) and I can emphatically say that the hybrid team is one of the worst experiences in my career. Decisions were made in some other parts of the world, really really early morning calls and a general sense of frustration for all.

In a completely remote team, you are forced to optimize for coordination and communication. Obviously you suffer the downsides because there is no water cooler, no joint information dissemination sessions, no war room accountability though you can achieve some kind of co-creation using skype, join.me, git and trello. However you gain some big advantages in terms of finding the right resource at the best cost, undivided focus if remote team members are given work packages and ability to exploit the timezone difference for a 24hour work cycle. Not to mention the humongous personal flexibility which it affords at an individual level.

A point to note is that this remote vs. colo experience really can come down to the individual members and their personalities. There is no one size fits all.

TL;DR Go completely colo or completely remote, half-colo + half-remote = half-ass. Team personality is a very strong variable in this equation.

The really amusing thing is when they buy huge LCD TVs and projectors to run IRC clients in an operations center.

And then call it "mIRC" because that's the crappy Windows client they use.
Don't imagine there is or ever was any difference in the positions of Democrats and Republicans on copyright issues. The Copyright Act of 1976 passed 97-0 in the Senate and 316-7 in the House. More recent major copyright legislation, the DMCA and CTEA, passed without even recording individual votes (voice vote or unanomous consent).

The US copyright law has been dictated by the media industry for a long time in something akin to regulatory capture[1]. Their lobbyists and lawyers literally write the law[2]. A revolving door sees former senators heading to cushy jobs at the MPAA pass RIAA litigators headed to the Copyright Office.

This is why the failure of SOPA was so shocking to the political and media establishment. Instead of the general public being fleeced for a few extra dollars every time they bought a movie or album, large businesses like Google had billions of dollars at stake and they wanted their interests to be taken into account.

Exactly. This is where having good engineering leadership can come in. A "mediocre"* developer can often be coaxed into producing great product with a little support from things like paired programing and code reviews. You'll probably increase his/her value and abilities in the process.

So you need your lead to be awesome. But the rest can just be good people who know how to code.

* this would be someone who may not fully grasp all the concepts and sometimes writes bad code, but is open to learn and listen. There are developers who write bad code and are arrogant/confrontational about their abilities. Those should be identified and fired as quickly as possible. They will sink your ship.
Interesting read as usual from the folks at priceonomics but it seems like a lot of the problems about pinpointing how people found them have solutions that work to some degree including:

- Provide a nominal discount with a coupon code "goog" so you know users came from Google. Or you can do a printed coupon with a tracking code embedded. I see coupons all the time for bike shops like Valenica and American Cyclery.

- Just ask how people heard about you. Most people will tell you because making up a story is harder and it'll be natural since your sales associates are so personable.

In terms of why the location works, my best guess would be because the mid-Market area is becoming gentrified as more and more startups move in and rents rise and young professionals with disposal income will pass by the store on their way to work.
Aside from the troll content here, you do have to be careful if you have e.g. spinal issues. Nerve damage can make even light exercise excruciating. I had to build back up carefully, never hyperextending, always keeping good posture, using light or (usually) no weight, focusing on weakened muscle groups, and never going to exhaustion, all of which is rather boring but was completely necessary. I do find that regular exercise helps with my neck and back pain, but it is certainly not a cure-all, and I worked out regularly before the pain started and definitely cannot do that type of workout any more. I've put back on about 15 pounds of muscle mass, but it's taken over a year of diligent work. On the plus side, my muscle tone is much better than it ever was from previous workout routines.
I often come across these types of comments about the IRC protocol being 'crufty,' 'old,' etc. I recently (a year ago) implemented a subset of the IRC protocol for a project and I thought it was fairly modern, and not difficult to work with.

Yes, IRC has some problems, it wasn't built with security in mind. I think dsl below offers a solution to some of these concerns.

But this still leads me to ask the question, what does a modern distributed chat protocol look like?
Luckily, it still does though the visa has changed from 1 July 2012. It's now a ENS 186. The relevant portions [1] are below. This visa costs 3060 AUD along with 540 AUD for the employer nomination, but that covers the entire family.

If you apply for the Temporary Residence Transition stream, your skills do not need to be assessed because you have already worked for your nominating employer for two years in Australia.

The larger screen of my Nexus 4 is a bit of a mixed bag. One-handed manipulation definitely takes some getting used to (you rest the phone on your finger pads, instead of gripping it), but the greater screen real estate is an absolute godsend for reading and web browsing. My old 3gs just feels nowhere near as useful as a web device when compared to the Nexus 4, so I can certainly see Apple releasing a competing product.
You do seem to know a lot about this topic, but I don't think you should draw any conclusions based on speculation.
