Yeah. In college I refused to help anyone except my closest friends and basically swore them to secrecy if I did help them. Otherwise everyone who downloaded some virus from directconnect or kazaa would stop by to get help as if I have noth

Your analogy to hedge funds is utterly inaccurate for most large funds. Smaller funds tend to take more bets but most large funds and fund groups attempt not to take on too much risk. If you got to a conference for large asset managers you

More likely is that the party leadership would not let them on any of the important committees. Or they may via backchannels fund a primary challenger.

So for me the real life tends to be much larger applications. I tend to worry less about the efficiency of something like quicksort in haskell. If I need very high performance from something I tend to use C anyhow. This tends to be very sma

In real life (not contrived examples) haskell greatly simplifies dealing with state. Isolating IO makes it much simpler to reason about where exceptions can come from.

Its also quite common in Hong Kong.

Not only that but my observation after working for 10 years in radiology is that many other departments either outsource diagnosis to radiology or at least want a study done. That way in case there is a lawsuit the finger can be pointed som

The vast amount of technology available is turning healthcare into a luxury good. There are newer and better technologies for treating many things available. How much is that worth?

Some specialties do. Its called the ROAD to success. Radiology, Ophthalmology, Anesthesiology and Dermatology. I know many radiologists who make between $500K and $1M. That being said residency spots in these specialties are extremely compe

And even if they weren't radically better there is very little that is easy to do other than destroying other countries investments that would allow a return to such a state.

Most of the issues mentioned so far are trivial or just warts. The real issue is understanding the design patterns that work well enough to build high performance applications. Also in order to really exploit the power and productivity of H

That is quite incorrect. Market makers are typically close to flat and are trading liquid instruments (assuming on exchange MMs like NYSE DMMs). The tail risk on a short duration trade of an exchange traded instrument is quite small, especi

That is quite incorrect. There are many firms with consistent low volatility profits. Market makers are a good example.

This specifically refers to a call of strategies that are the equivalent of writing a put option. The short term cash flows from the premium are not commensurate with the tail risk. Both LTCM and CDS on subprime are examples of this type of

Interestingly I had this exact conversation last week with a guy from an HFT firm that was asking about how do you write fast code in haskell. Haskell won't be as fast as C, but we are not a high frequency shop so it doesn't matter. Much ti

This project is not HFT. It does not use a full book data feed. Really even the feeds that come from the exchanges are not precisely timestamped enough and HFT firms stamp their own . The data is not huge although trading system need to be

If we let the banks go down should we have let the counter parties go down as well? Should AIG have gone down? While I agree that it would have been better in the long run to let them fail there would have been tremendous consequences to do

If they paid for the clinical trial then there should be some sort of protection for the person who paid. Otherwise it will be impossible to expand what a drug is used for after the patent expires.

I would assume that if one would deploy a strategy live then it would be done with something like Interactive Brokers. They do allow directed orders although if you cancel them they are not cost effective.

x::xs or x:xs in haskell is a very common naming pattern for pattern matching on lists. head and tail are functions that operate over lists so using them as a variable would be considered name shadowing. i is good to use as a loop counter i

I have seen it even worse in medical and dental school. And because there is little ability to replace the lost revenue from expelling a student the schools are typically lenient.

Not all of us keep all of our notes forever. If the expectation is that they should be kept the University should note it (and maybe they do). Mine did not.

What you are looking at is a graph of the liquidity in the order book over time. A security does not have 1 price it has 2, the bid and the ask. The difference is called the spread. The bottom is showing the amount of liquidity at each pric
