I concur. Microsoft is now an important and helpful part of the open source ecosystem. For the most part, they've been generous and engaging with the community. Also, the commercial products seem to be living in harmony with their o

IIRC, the 90% estimate is based on how often searches encounter previously cataloged objects.

To me, the headline feature for Python 3.8 is shared memory for multiprocessing (contributed by Davin Potts). Some kinds of data can be passed back and forth between processes with near zero overhead (no pickling, sockets, or unpickling). T

If I'm reading this correctly, it is very close to what Python has been doing for over a decade, so I am not sure that using a "rejection method" counts as "new tech". Here are the relevant snippets. Code for shuff

Presumably, getting caught and convicted introduces a selection bias away from the traits you just listed.

Multiple social priming studies are cited. This is a warning flag given how replication crisis was most pervasive in that entire field.

By 1969, this was already a common meme. One example from 1967 was from the "Court Martial" episode of Star Trek: KIRK: Yes. (Notices the piles of books everywhere) What is all this? COGLEY: I figure we'll be spending some

This is a nice bit a progress and addresses a major concern about using PyPy in real-time systems.

Ironically, the provided implementations for Queue and Deque are algorithmically terrible, giving O(n) performance for operations that should be O(1). Queue and Deque could easily be developed from first principles by building on dictionari

I think almost every programmer would benefit from reading "Refactoring". It sharpened my skills quite a bit, and I was already experienced before encountering the book. The book was an easy read and was an efficient use of my ti

In Python 3.7, the Timsort was sped-up another 40 to 75% for homogenous lists (just some of the common cases). It works by replacing Python's slow generic PyObject_RichCompareBool() with a type-specialized comparison function. * https

Thanks for the nicely written Python/Rust comparison :-) Is Rust's flat_map() equivalent to this in Python? def flat_map(func, it): return map(func, chain.from_iterable(it))

These topics are discussed in greater depth in Kasparov's book, "Deep Thinking". My view of the book: Very well written (and occasionally engrossing), well thought out, and strikes a more hopeful/reasonable tone that an

ISTM the F-35 will be the undoing of the U.S. military. The program seems to be eating all available time and funding but without delivering on essential core capabilities.

This patch was a little aggressive and may get reverted (it caused immediate code breakage in downstream distros and projects). Changes like this typically need a deprecation period (that said, to the extent the current feature didn'

> There is no reason for this to expose a tuple API. FWIW, that is a norm in the standard library that predates named tuples. For example, sys.version_info and time.localtime() return structseq instances. Those both have a named tuple A

I concur :-) Otherwise, use a dict, types.SimpleNamespace, python-attrs, or a custom class. FWIW, the origin of namedtuple() was that some variation of it had been re-invented many times and this tool brought together the common features of

One purpose of _source is to make the namedtuple self-documenting -- that has been a considerable benefit over the years and has resulted in many fewer questions and issues than we usually get about our other tools. Another purpose of _sour

To be clear. I never said that start-up time wasn't important. Instead, I pointed out that in the previously studied example, the measured impact on start-up time of a single named tuple was a fraction of a millisecond and less than
