The only way someone front running causes you actual profit margin problems is if your profit margins rely on trading a large volume in a given time period, yes. This essentially means you're profiting off an understanding of volatilit

The origin of the term is kind of comical to modern ears: The terms originate from the era when stock market trades were executed via paper carried by hand between trading desks. The routine business of hand-carrying client orders between

There is no steamroller in this approach. Perfectly exploited, you act as an infinitesimal holding-time middleman that has zero probability of not being able to sell, since the future queue is already known. You buy enough so that the real

In 3D the cross product can be understood as follows: -You define the cross product as the area of the parallelogram formed by two vectors, -Draw a normal to it, -Use some convention to decide on which side the normal should stick out such

The problem is the increment operator now gives two possible answers to a++. This can't be done without relying on some notion of state. That state has to be stored somewhere. The distinction you're looking for is "does this

By the way, one way to describe idempotence is a function whose range is the fixed points of the function. Fixed point is very close. Your idea here is that google_search_lucky(search_string) , where search_string="google" retu

They have phone operators. Each of which has to sit somewhere. And have some kind of manager. Uber coordinates 15 million rides per day [1], which assuming a phone operator coordinates 20 rides an hour (unrealistically efficient-- in realit

Is this just because it's hard to distinguish using visual data when it's a 2-D image on the road (from the sun, intentional paint, a spill etc) and when its a 3-D object sitting upright on the road?

Duh- reading comprehension fail- cheers. Same question though, there is still something that makes me uncomfortable about using exceptions as an expected-case control flow structure (as in, this is expected to catch an exception once every

I'm not a particularly experienced programmer. It is a sign of my immature taste to find this ugly? The idea of assuming any exception thrown will be the exception we expect (outside iteration limits) seems like an unnecessary abuse

Does anybody know how difficult these problems are to solve once you've already calculated the relevant kernel? Let's say I had that kernel stored in a database, is it just a matrix multiplication or two to calculate the solution?

Something about the framing of this irks me. The idea that we were all confused about how to feel before she set the tone doesn't resonate with what I experienced on the ground. We were proud of Jacinda Ardern because she reacted how w

This is some of the best maths writing I've ever seen. It really gives you an accurate feel for the results they've derived.

Agree. It's standard quadratic medium rectification, and they've dressed it up so much they can't see it. The rectification will be associated with a uniform translation of the sample the sound wave travels through.

I can't read the paper but the physical mechanism for how anything like this manifests is so obvious they'll be embarrassed to miss it: the entire solid must translate a small distance.

That's not entirely true. There are also bits associated with ambiguous combinations of single base pairs, so there is actually 4 bits of information if all ambiguous combinations are possible. But it'd be much closer to 2 if you

I don't understand why he's not encoding information into the odd labelled columns. It really takes away from the project.

This is a partial transcript of the Q4 2018 earnings call. There is a strong case to be made that the information was not market moving. Operator Thank you. Our next question is from Colin Rusch with Oppenheimer. Colin Rusch Thanks so much.

They define a rockstar as someone in the top 1% of productivity. In order to know how many average employees that equates to, you need to know something about the distribution of productivity across employees. Only then can you judge whethe

Your first two paragraphs make a very important point. Outliers from every cohort exist, and often it is due to a kind of inner drive, and we should not ignore that truth. Your final paragraph is cruel. From every cohort the vast majority o

On the flipside. Let's say you eat 300g of beef a day, every day. Let's say a full grown cow will give you 300kg of beef. In order to fuel this habit of pretty intense meat consumption, you have to kill a cow once every three ye

People don't like to be in situations where they are stack-ranked according to a skill they are bad at. Stereotypical jocks lose when you stack-rank them in a random math class, so the second they can drop maths they do. And before tha

There's a trivial solution to this kind of problem. Frequency filtering. Essentially, you make sure that your light source beats at a peculiar frequency, and then you only look for signals in that beat with the same frequency. So you&#
