Time moves faster in a dream than it does in the real world. Code running in a container runs slower than in the outside world ;-)

FWIW, I worked on a switch/case for Python about ten years ago and abandoned the effort because it reached a dead-end. Without the ability to mark variables as constants, a switch-case can't implement an efficient jump table. And

Thank you. This was a nice Rosetta Stone language comparison using an interesting problem with beautiful diagrams.

My least favorite part of Python 3 is the new 28 byte int structure which spills over to 32 bytes at 1,073,741,824 (2^30). >>> sys.getsizeof(1073741823) 28 >>> sys.getsizeof(1073741824) 32 As a directl

So, your prediction for Game of Thrones is that the White Walkers will bring about peace and unity to the competing factions of the Seven Kingdoms ;-)

I really enjoy seeing thought-provoking posts like this on Hacker News. The practical insight is that complex systems have some level of scale where causality experiments yield the most fruit, and that this effect is measurable. The most in

For those who are interested, CORDIC (for COordinate Rotation DIgital Computer) is another technique from that era. It "is a simple and efficient algorithm to calculate hyperbolic and trigonometric functions, typically converging with

A programming language is a door. It can be easy to open (Python) or take more effort (C++). The reason to open a door depends on what is on the other side. The Python door opens to a large and playful room with about 100,000 packages rea

For user defined templates, using string.Template() is a good alternative because it does not do multi-level attribute lookups. The single mapping lookup is safer. Also, the syntax is simpler, making it more suitable for exposure to end u

FWIW, the article incorrectly attributes the original idea for the compact dictionary to the PyPy team. That team implemented it based on my research, proposal, and proof-of-concept (see https://mail.python.org/pipermail&#

I've always found Armin's posts to be intellectually honest and thought provoking. And unlike your ad-hominem comment, he itemizes his concerns and provides details (such as the performance comparison with David Beazley's cu

I agree with this important article. In the large open source project I work on, we have a prolific contributor who is systematically going through the entire code base, "refactoring" some of it in way the impairs my ability to re

I wonder whether the authors consider "value = somedict.get('somekey')" or "match_object = re.search(pattern, somestring)" as returning a single type. Both of those common calls can return None. I'm also
