I beg to differ on Death's best album. I would say they realized their true style on Human and peaked with Individual Thought Patterns and Symbolic.

Agreed. I guess, this way it's easier to train people to avoid clicking on links they don't recognize.

This can be done in a variety of ways, but it's unfortunately not usually free. 1) A trading terminal such as Bloomberg 2) get API access to subscribe to the exchange feeds or other data vendor feeds. Usually, this is out of reach for

I'd received an email on my corporate email address from some courier service claiming that they weren't able to deliver a package to me. The email also contained a link which upon clicking took me to a page which displayed the me

I remember someone referring to this as "intent driven programming". I once worked for a company that made a business rules engine. The idea was to describe a flowchart to the system and the software would ask what you wanted to d

I won't say these are flash crashes, but it's very normal to see 6 or 7 sigma events in Treasuries. Such large deviations are very rarely seen in stocks

I guess that depends on how close to the exchange you want to be. If your strategies were extremely latency sensitive, you might want to have not just the execution logic, but the larger algo framework on there too. This is particularly tr

The FPGAs run entire algorithmic strategies. It's not just the order management that they handle.

You could start with a book like "Practical Data Science with R". This review http://www.amazon.com/review/R3IOXEI69G6044 gives a very good summary of it's contents and the intended audience

This is a very useful guide. Although I'd imagine that you'd have to have atleast some experience with ML before you truly appreciate what's being explained in the paper.

I'm just speculating here. Maybe the seeds of other trees are not as tasty for rodents? So other trees might not be facing the same problems as the bamboos, and could have a better chance of survival

I'm not sure if I understand your question correctly. kx provides shared libraries to make R and q talk to each other. The specific approach I followed used a shared library that brings R into the kdb+ memory space, meaning all the R s

I do not have experience with Julia. I'm interested in languages built for time series data specifically. APL derivatives shine in this regard, in the sense that they provide the bare metal language composed of a few very powerful verb

While this is a good concept in theory, I'd be skeptical about building on top of such a system. The primary reason is the slowness of R. I built heavy duty data mining systems using a stack of kdb/q and R. In my experience, R, wh

D language is also worth taking a look at. It's a very smart language designed for systems programming.

I don't have numbers handy. The real power of kdb+/q comes from the column oriented architecture and the extremely powerful vector functional language q. The language q is inspired by APL. I highly recommend you to check out this

Many banks, hedge funds use kdb+/q for time series databases. This (very expensive) software is literally unheard of outside of these niche domains. I've been using it for close to 5 years for high frequency data, and honestly not

I agree. Psychedelics give access to altered states of mind. Very often, these altered states are mistaken to be transcendental states (like what yogics and other saintly beings experience). It's best to avoid these shortcuts to the mi

>>One exchange's shadiness will always affect every other exchange. I don't think that is correct. A shady exchange will be avoided by market participants if it significantly deviates from a fair price.
