> I place a bunch of trades around 25% below the current stock price

Funny, we sat around trying to figure out the right price and this is what we came up with as well.

Too bad this doesn't show up in second level quotes, it would be a good leading indicator of what funds in general thought the chance of a crash was on any given day:)
This looks really cool. I'm excited to try it out, individually and with others.

Even better that you can immediately sign up and give it a try. As opposed to Asana, which has similar intentions, but is doing a private beta with larger companies only. Yes, Trello is much easier to get excited about.

EDIT

Some feedback: so far I really like it. It's intuitive. And it has some nice features out of the box that are lacking in other products such as assignment and voting. Assignment allows central authorities to exist, as well as hand-offs between people. Voting is awesome. I immediately see two uses for this: democratizing, and to allow collaborators to vote on what they want to do. The latter being something I've always personally wanted in a collaboration tool. Combining that with a central authority can be very powerful by allowing people to voice their interests, yet keep the project moving and avoid conflict.

As for the initial reaction: some of the views are pretty intimidating. Even thought there's only three lists at the start, it is still a little much to begin with. A lot to take in. If you ever implement a "minimize list" feature, that could easily reduce the noise for a beginner while still allowing you to explore all the features when you're ready to.

The edit screen has a lot happening in it too, but I think that's less of a problem since it's only visible when actually editing cards and you'll soon be using everything in there.

Also, I'm sure it's already in the works, but keyboard navigation will be huge for upcoming power users. Right now Vimium provides that for me, but it'd be great to have it built in.

It looks very useful! I'm already having fun with it and I'll try it out on an upcoming collaboration. Is there going to be a UserVoice (or similar) site anywhere for additional feedback? I'll happily leave this and other feedback there.
They both resemble this more than anything.

Google has a dual-class stock structure which gives class B holders (Schmidt, Page, Brin) 10 votes per share v.s. 1 vote per share for the rest.

This is relevant to your statement, because while it's pretty much a requirement for a publicly held company to pursue profit at any cost, it's not necessarily the case for a company run by the people that have a disproportionately large number of votes on major issues.

I'm pretty sure they still have over 50% of the votes, so together they can decide how Google will handle tough moral issues without any support from other shareholders.

I would argue that it's entirely plausible that a couple altruistic billionaires will sacrifice a few dollars in pursuit of non-evil (their opinion of non-evil mind you).

I have a number of small business clients who have been looking for something exactly like this. I'm going to be telling each of them about it the next time I see them.
I think the #1 reason why games don't need a lot of automated testing is serialization, or rather the common lack of it in most game worlds. If the data gets corrupt, you can reset the game and all is well again. When the rare corner cases pop up, it's easy to play whack-a-mole with them, because they're all "shallow" in the sense of the game starting from a clean reset frequently, so you can usually reproduce the bug quickly.

Of course, if the game does need heavy-duty serialization of everything, all bugs are potentially deadly. And this is largely the case for the line-of-business, social, and productivity apps, because that data is considered mission-critical. Corruption is not OK, reverting to backups is to be avoided. When a game has that kind of requirement, things get a lot tougher - and so games have naturally evolved to favor minimizing the save data to nothing or a few stats.

And this is borne out by looking for contrapositives. There are two genres that have a history of tending to be buggy because of some form of long-term data corruption: Large-scope RPGs and turn-based strategy games. It's hard to reach the bugs in those games, so it's also hard to fix them.
I agree that gmail only having offline for certain browsers is suboptimal for the web (though they claim, like amazon with their kindle app, that they will expand support), but it's worth noting that at least the gmail app includes an installable component equivalent to an extension...and there are plenty of single-browser extensions for every browser.

> I am also against the ability to trade by borrwing money from brokers (margin trading or leveraged trading). If an individual trader screws up, they wipe themselves out. If they borrowed money, then the consequences of their bad trades starts to seep out to others. If more than a handful of traders, trading on margin, go belly up, the lender could be in trouble as well...you can see how this could ripple across a system.

In theory, shouldn't those giving the loans account for the risk and thus be protected from wiping out themselves?

"-75% of trading is now automated, it is just computers trading with each other.

I hope someone will correct me if I'm wrong but I have never figured out if this 75% includes algo trading. If it does include algo trading (my guess is that it does), then I'm surprised it is not 100%. That is like saying 95% of TV channels are controlled by remote-control devices."

From the Foresight project homepage (http://www.bis.gov.uk/foresight/our-work/projects/current-pr...): "For example, today, over one third of United Kingdom equity trading volume is generated through high frequency automated computer trading while in the US this figure is closer to three-quarters."

Ask HN:  What is the best ad option for my startup?
I'm a co-founder of a startup that is doing fairly well, 100 days in. Traffic is growing on almost a daily basis and unique visitors, page views, etc. - while not massive - are promising. I've been told that ad sales for sites with over 100K unique visitors per month are on another tier in terms of expected CPM and advertising credibility.

My question is: let's say our site is pulling 25-50K unique visitors per month of a fairly specific audience (demographic-wise). What would the HN audience recommend for our site to do, in order to maximize ad revenues? We've tinkered with Google Ads and some other options but, as traffic picks up, we're beginning to look into it more seriously. The difference between $0.25 CPM and $2.00 CPM is obviously huge, once traffic scales to a certain level. Do all of the ad networks pay the same (roughly)? Are all of the ad networks created equal or are there some we should reach out to that might be more selective, and therefore more rewarding?

Another related question (for those who have ad sales/buying experience): what should we project as an expected "going rate" CPM for a site with moderate traffic that reaches primarily college-educated males in the 25-50 age group?
I've had Crohn's since I was 12, and have often contemplated creating a tool to help others track their diet and activity, to look for correlations. I've not done so because I was afraid of either (a) FDA interfering, since it's medical-related; or (b) liability in case there was a bug.
Previously the vast majority of investors were buy and hold, where they believed in companies and that their earnings would increase. Of course, there were always traders like Jesse Livermore that traded off of order flow, but those were the minority. Most were like Warren Buffett where buying and holding was for the best.

Now the majority of trades are done by algorithms with no biases at all towards the earnings growth of a company, be it HFT, or statistical arbitrage, or through other quantitative models.

HFT accounts for 75% of daily volume, and by definition, HFT does not take into consideration things like future earnings growth, etc. For the most part, they simply find arbitrage opportunities and profit from them.

So stocks being bought and sold are not done based on the earnings potential of a company. Case in point, Citigroup before the reverse split was trading hundreds of millions of shares per day, not because so many people believed in the company, but because it was dominated by rebate traders, HFT, day traders, etc. I believe companies like Fannie Mae and Freddie Mac were trading millions of shares before they went pink slip, even though it was known that they were defunct.

What Gruber is arguing about, and I would tend to agree is that Microsoft has "released" Windows 8 on top of a tablet that is nothing like what a tablet would ultimately be. It contains a full Core i5, with fan to keep it cool and all.

Would it have been better to wait till manufacturers were ready with their ARM based tablets that run Windows 8 rather than something PC like that runs Windows 8? Especially since based on the current demo device we will have no idea what Windows 8 will be like on actual low power hardware...

Not sure exactly what you're asking, but the fact is that trading has been drying up. Since 2007, volume has plummeted, and August I believe was one of the worst, if not the worst, month for people withdrawing from mutual funds. Less and less retail are staying in the markets because of the volatility.

So I don't know if it will get cheaper to buy and hold. It will definitely get more volatile.
OK, since we're using profanity, here are my thoughts:

How the fuck did this POS get upvoted? I wasted 2 minutes (including the inserted advertisement) watching this video and the guy hadn't said anything. That was way too long for me to waste on a video of questionable value. Secondly, the link-bait HN title is not the title of the video. Submitting, then up-voting this kind of bullshit turns HN to shit. </profanity> Profanity is so overused. It can be artful at times, but it seldom communicates any information, or real emotion, and is a waste of the reader's bandwidth.

I place a limit order, which I guess you could see if the depth were deep enough, but I could very well have programmed an algorithm to just monitor the prices and do market orders instead, which you definitely wouldn't see. I'm sure most traders do it that way.

The interesting thing is that on the day of the Flash Crash, if I'm not mistaken the ES futures contract bounced exactly off the 200 day MA. So, one thing that the flash crash revealed is a lot of algorithms programmed into the markets that would normally never have been revealed. So if you want, keep a floating order just above the 200 day and you might make a few dozen points in a few mins, just like May 6, 2010!

Outbound/return is standard terminology all over the travel industry. Including in UK and US, and for trains and for planes: I'm surprised you're not familiar with it.

"Depart" means something different: it refers to the beginning of each leg of the journey. Its opposite is "arrive". So you might have an outbound leg which departs from LAX and arrives in SFO, and then a return leg which departs from SFO and arrives in LAX.

Honestly, I'd be careful saying something like that. Given that it's a disease involving the intestines, most people don't want to hear about it, and thus most people with the disease don't typically talk about it unless asked - and so a lot of people who have it don't mention it at all. It wasn't until I was diagnosed with the disease that I ever found out the people that I know who had it (and, in turn, my mother found out her friends who had it, or their sons, etc.).

Likewise, I don't generally tell people - it's not usually relevant to discussions, and no one really wants to hear about it. Chances are you know people who have it, but they've just never said so.
There was something similar to this in August 2007. A bunch of quant shops blew up, and I believe if you look at the volatility index, it spiked up hugely during this time.

I don't see why you think it's not valid. You're taking an app that was designed to run in the browser, tell it to use different namespaces and it runs on this new Metro UI interface, phone, and tablets. You keep the same XAML, same code, and only tweak a few things to make it work on a new platform. It's a similar process to how you tweak your css/js to run in different environments.

And what do you mean with existing production code? I imagine you can run still run it in the browser like it's currently working.

Facebook Ads has traction as a serious, targeted ad platform. You can drill incredibly far with your demographics and interest groups and still get a very chunky network reach.

By and large, networks are the same but they're completely different at the same. Places like The Deck or BuySellAds you'll more than likely see a lot of blog traffic coming in but you can also expect high bounce rates (this I say from experience). Google AdNetwork/Doubleclick you might get a completely different number, with more varied interests/keyword results, but spend longer time on the site.

My first question is where's the API? This is something I plan to use but I will want some way to export the information to non-users, dead trees, etc. (I'd need it anyway for private boards, The boss wants it in excel etc.)

I'd also like to question the wisdom of closing the 'public' content off from non-users. Choosing 'Public' will make the board visible to all Trello users. Very closed-web, I don't use Orkut anymore and I wouldn't be on github if it wasn't so visible and ubiquitous. Not a complaint, just food for thought.

Note that /r/math on Reddit is using those delimiters because that's what Tex The World uses. I don't see any particular reason to use those over just sticking with the MathJax defaults, which are backslash-brackets and dollar dollar for display math, and backslash-parens for inline math.

For your script, this can be achieved simply by deleting the line in the configuration that sets the inline math delimiters.

I've tested, and the default delimiters seem to work fine on HN.
