This article is long on inflammatory language and short on analysis or evidence. There are plenty of real issues with HFT as currently practiced (front-running data feeds, gaming with flickering orders, dark pools, etc). However, the artic

I've had good success doing public code review sessions at conferences where the goal was simply to generate discussion points rather than to catch errors. The discussion center around how to use the language more effectively and sometime v

Likewise, when an automated stock trading program makes unfavorable trades, the company running the program is responsible for those trades. To the extent machines are allowed to proxy for humans, the humans are fully responsible for the ac

A false cognate in Python is super(). It does something much different than super in other languages -- calls to super may call some class that is not a parent of the class where the call originates.

Too bad that a horrible answer was selected as the best. The minheap/maxheap solution requires that the entire stream of integers be stored in memory. There is a fast and memory efficient solution using Indexable Skiplists: http://code.ac

Overall, this is a nice post. There are two quibbles though. 1). For the most part, "c = collections.Counter()" is almost always better than "c = defaultdict(int)" * Counter only supplies missing values rather than automatically insertin

This article contains excellent recommendations except for one (the numbers.py module is nearly useless).

FWIW, Michael Foord's mock library has been approved for inclusion in the Python's standard library. See http://www.python.org/dev/peps/pep-0417/ and http://www.gossamer-threads.com/lists/python/dev/973274

Python's unittest.py was a direct port from Java's JUnit. More recently, a Google contribution to unittest.py added a huge number of self.assertThisThatOrTheOther() methods. The new methods were designed to have better diagnostic messages

This is a wonderful recap of the different ways of expressing the same idea in different languages. It is a fine Rosetta Stone. That being said, it would also be useful to characterize features that are completely unique to a given languag

Why was this downvoted? Margins are a relevant topic when discussing the survival of a business, and a "tragedy of the commons" is relevant when discussing the failure of a segment of business upon which all the others depend.

Retail store fronts don't have any problems that cannot be solved by better margins. If the publishers valued the service offered by Barnes & Noble, the obvious solution is to grant lower prices to brick-and-mortar bookstores. According

I've long been a big fan of this book. It will make you a better programmer even if you don't program in Forth. The only downside is that it will feel dated (because it is). Many of the ideas that were once progressive, original, and a b

I also like list(s) for its clarity and universality (the same technique works with dict(m) and deque(d) for example). The s[:] gets called faster (builtin syntax dispatches directly) than list(s) which requires a global lookup. One called
