For me, it's not so much the leaves or the trees themselves but taking a moment out of my day just to sit there and do nothing. It's a form of meditation. The leaves, trees, waves, etc... are just there as a sort of visualization for your moment, and usually you'll notice things about them that you normally don't. Just because my time is valuable doesn't mean I'm going to make sure I spend every minute of my time as efficiently as possible. Sometimes I just need to sit on the beach and watch the waves crash. Or sit on a park bench and watch the people walking around.
The US steel industry would be fine if all the foreign steel producers raised their prices to try to screw us. The problem with US steel is that foreign steel is cheaper.
They should have made more money rather than publishing more quickly. It used to be possible to do these sorts of things to the stock market but when these sorts of regularities are discovered the process of exploiting them also eliminates them once enough money is being made. Heck, a major trading firm got started by noticing that stocks went down on the weekend (and of course they don't any more).

When someone leaves a position like this, and then attempts to re-enter the workforce a few years later, are they able to do so at around their old salary? Or have they lost the bargaining chip and must restart substantially lower?

He didn't say anything specific that I disagree with, except maybe placing responsibility for the Ukraine situation at the West's feet. That was effectively a Russian invasion, nothing more, nothing less.

You cannot throw your toys out the pram when Europe rightfully gives you an economic black eye for invading one of their neighbours. And screaming that Ukraine was in a short skirt and "asking for it" doesn't really help your case any.

The terrorism funding issue I'll agree with. The West does it over and over again (particularly the US and UK) and then pretends like they're surprise when it blows up in our respective faces.

We also funding ISIS a bit via Syrian rebels before we stopped.

For market sentiment you are just showing tweets. How about if you just show if market sentiment is +ve or -ve?

I think you are taking only fundamental analysis into account to suggest buy or sell otherwise you would not suggest GPRO as a buy.
Didn't expect to see this here (I am the author). For the record, I implemented this syntax as a Racket #lang called LISO[1], and I also used a variant of that syntax for a language that compiles to JavaScript, Earl Grey[2]. It's fun to play with.

Have you run your %w[Buy Sell Hold] indicators over historical data to see how accurate your suggestions are?

They didn't include any discussion of:

1) execution (are they expecting to buy on the bid and sell the offer?).

2) commissions. They only made 3,362 yuan on 2,872 trades. A yuan is about 12 cents, so they are making 15 cents USD per trade.

A .1% commission would cost them roughly 5 yuan per trade, but they are only making 1.17 yuan/trade.

It's incredibly unfair because the members of gamergate that aren't spewing misogyny and hate can't really start another movement, that movement would just be taken over by the same people they are trying to distance themselves from. So they can't distance themselves from the hate and their movement is being attacked because of the hate coming from these interlopers and Gawker/The Media is going to just continue to inflame the haters.

Well, wouldn't you? Even if you never subpoena a single data point, there's a vast trove of information out there for the taking just from what people choose to put on FB.

The real value for intelligence is as a social science project. For example you became aware (through other channels) that unrelated individuals X, Y, and Z have taken up terrorism; if they were on Facebook then it's worthwhile to search through their profile history over the previous few years to see if there's some common behavioral pattern that's strongly correlated with people who actually take up arms instead of just posting support for their political cause of choice.
Airbnb seems like a terrible choice for last-minute booking because it's based on the notion of hosts responding via email in their spare time. When you book a room in a hotel you have reserved a room and don't need to do anything more except show up but when you book a room via airbnd you have merely made an inquiry and won't know whether you've reserved a room until you possibly get an email back after some non-deterministic amount of time.

Selection bias says the most responsive hosts will get booked early so the bookings that still show as available at the last minute tend to be less responsive hosts. A room that's still showing up as available at the last minute might be doing so because the host went on a hiking trip and forgot to update the calendar rather than because it's actually available.

I am a Catholic too, though marginally attached to the Church due to multiple and systematic dubious ethical decisions from the top of our clergy hierarchy (of which the de-facto protection of pederast priests is just the tip of the iceberg).

That does not mean I will go around finding reasons to criticize everything they do. They have (presumed) legitimate possession of an invaluable wealth of historic documents. It is therefore their prerogative to decide to whom they give access to it. It is a good thing they decided to digitize those documents and put them on the web. It is also a good thing they will have open access for free. What the heck are you freaking out about?

According to your logic, this is a "boneheaded announcement" because of what? Because they are looking for means to finance the operation without forking out their own money?

I would definitely recommend his short stories. Most of them are excellent and it's a small investment of time so you can try several to get the feel of his work.

If you're reading novels, "Martian Time-Slip" is a good first Philip K Dick book. Although I really enjoy many of his books there are several that may put you off reading more if you read them before you have an appreciation for his work. Martian Time-Slip will give you the flavor of Philip K Dick and show you how innovative and interesting he was as a writer. If you don't enjoy that one I think you will probably not enjoy most of his other novels. If you started with "Confessions of a Crap artist" or even the acclaimed "The man in the high castle" for example you might not have the best first experience with his work. "Ubik" (also mentioned in this thread) is another good choice to start with.

Microsoft would hire someone like this back in a hot minute. For lower level Microsoft people who leave, they can come back at a higher level.

Microsoft needs great people. He will just have more experience in new and unique ways, so he will be more employable.

For Microsoft employees who hit a level and can't get higher, they can probably go to a startup for 2 years and come back at a higher level at Microsoft.

This is short-term trading. "Every two seconds they predicted the average price movement (on OKcoin) over the following 10 seconds. If the price movement was higher than a certain threshold, they bought a Bitcoin; if it was lower than the opposite threshold, they sold one; and if it was in-between, they did nothing." I don't see them allowing for commissions and fees.

OKcoin, at peak, had a trading volume so high that it's generally considered to be fake - the exchange operators manipulating the price. What this group at MIT may have done is reverse-engineered the fake trade generation algorithm.
I own a Surface Pro 3.

Not too shabby. The onscreen keyboard sucks ass (worse than the Windows Phone 8 keyboard in every measurable way), and is a little buggy (e.g. typing a single letter into Chrome's URL bar causes it to close for no reason).

The keyboard cover is wonderful, no criticisms. The weight is acceptable. The pen works well but isn't "required" for a good experience (although I am at 200% DPI).

The thing gets worryingly hot (too hot to touch in places) and the fan doesn't kick on for quite a while. High network activity seems to result in excessive heat in particular which is strange (e.g. a 7 GB download in progress generates more heat than full screen YouTube).

Overall I'd likely get one again/recommend it. I just worry that the heat will eventually damage it internally...

PS - You cannot use it on your lap with the kick-stand. Just doesn't work. You can use it on your lap in "tablet mode" fine and the kick-stand works well for tables and similar. The kick-stand is great, but a laptop's rigid hinge is better on your lap/legs.

I seriously doubt that's what's going on here. You can't really approach gentrification like that. You'd quickly run into issues with the local government and regulations.

My guess is that this is speculative property investment, likely as part of a private REIT/hedge fund. I bet the buyers plan to turn around and sell these off in small lots (usually 10 - 100 at a time) for a small profit.

I think you are confusing your personal use case with everybody's use case. What's a "normal app" anyway? Did you mean to say "apps I use on a daily basis"? Because of the 17 apps on my home screen, 6 do not have a functional requirement for internet connectivity. I bet for users in emerging markets this ratio might be even higher.

For most people, spending money is something that actually matters. Again, just because you don't have metered data, doesn't mean everyone else is in the same situation.

Google manages to sort millions of search results by relevancy, I'm sure they can do the same for app permissions.

If everyone began using the paper's strategy, would the strategy still work?

Also, the strategy seems less effective than portrayed in the news article. If you look at the "results" section, it seems like the profit flatlined shortly after starting, then had success due to some major trading event, then eventually flatlined again: http://i.imgur.com/CBjEjgo.png

Wouldn't it be more accurate to say "this strategy is effective under some very specific circumstances"?

Also, does anyone know how equation 4 was derived? http://i.imgur.com/vkx8ZEC.png

It seems like the key insight of the paper, but there's no mention of where it originated from. Is it a common equation in statistical modeling? I'd like to learn more about it. Does anyone have any suggested reading or coursework I should study?
Depends on how the speculation is defined for the investment. If the speculation is that one can buy low and sell high, then no problem. If the speculation is that one can buy low and convince others with falsehoods to buy high, then that's a problem.
Can a HFT-knowledgeable commenter chime in on the viability of the Sharpe ratio here?

From a physics perspective, it appears that the Sharpe ratio of 4.1 is roughly equivalent to a 4.1-sigma claim that their algorithm is better than random trading. I can't check easily, but I'd guess that the movement of Bitcoin prices isn't normally-distributed (looking at the paper's time series suggests that there's more low-frequency power there). If so, I'd guess that a more robust measure of the claim's significance would show it to be less significant.

Put differently, I'd guess more than 1 in 15,000 random sets of 2872 trades (their number of trades) would yield comparable profit. Furthermore, a simple buy-and-hold would've yielded a 20+% return over the same period.

I am not surprised it bent with both the amount and way he was putting force on it, but I genuinely didn't expect it to just "give" that suddenly and completely.

I will say the iPhone 6 "bendgate" issue was completely overblown, but I am happy this issue is getting media attention. Maybe it is something manufacturers will take more seriously in the future.

You can actually make a device fairly bend-proof without adding too much weight, it is just something that has to be given engineering time to accomplish and I hope all manufacturers do that in the future.

With phones getting thinner and larger they will get more bend-able.
At first I wasn't sure if there was background noise, or if it was just my laptop fan spinning up.

This is good advice. Good to talk about in this context.

But I also see this advice given a lot in response to callings-out, and that's often really destructive. It comes across as you saying the person being violent is OK. It's the person calling them out who has the responsibility of saying everything in the perfect even handed tone to get the violent person to listen.

When the person doing the calling out is the recipient of the violence that's a particularly nasty connotation.
Options might not be the best advice for the target audience.
> What this group at MIT may have done is reverse-engineered the fake trade generation algorithm.

Just to be clear, there is nothing wrong with this. Infact, sitting around and reverse engineering what other traders are doing is what many funds do. I'm in this group so I"m happy to answer questions if anyone has any.

> Every two seconds they predicted the average price movement (on OKcoin) over the following 10 seconds. If the price movement was higher than a certain threshold, they bought a Bitcoin; if it was lower than the opposite threshold, they sold one; and if it was in-between, they did nothing.

To be clear, this is the core of what most HFT systems do these days. Consume many different factors, give each factor a decay factor to tell the system when the signal goes stale and distill them all into a value that says, but or sell or stay.
