Do not use requirements.txt
Are you developing a backend service in Python? I have two pieces of advice for you: Do not use pip and requirements.txt to manage Python dependencies. They lack crucial features that should be built-in. Use Poetry instead. To me, the first one is a no-brainer. The second one is more tentative: Poetry is a great option, but it’s hardly the only option worth considering. I’ll explain below. pip’s m
Python is a Compiled Language
This blog post hopes to convince you that Python is a compiled language. And by “Python”, I don’t mean alternate versions of Python like PyPy, Mypyc, Numba, Cinder, or even Python-like programming languages like Cython, Codon, Mojo1—I mean the regular Python: CPython! The Python that is probably installed on your computer right now. The Python that you got when you searched “python” on Google and
NEC、Pythonを用いたデータ分析を高速化するソフトウェア「FireDucks」の無償提供を開始
NEC は、プログラミング言語「Python」を用いたデータ分析において標準的に使用されているテーブルデータ分析用ライブラリ「pandas」を高速化するソフトウェア「FireDucks」を開発しました(注1)。データ分析に必要なデータの前処理を最大16倍(注2)高速化し、データ分析にかかる時間の大幅な削減とコンピューティングコストの低減に貢献します。 また本日よりFireDucksのβ版をオンライン(https://fireducks-dev.github.io/)で公開します。どなたでも無償でご使用いただくことが可能です。 近年POSやEコマース等の売り上げデータや金融取引のトランザクションデータなど、大量のデータが容易に取得できるようになりましたが、それらデータから価値ある分析結果を導き出すためには、人工知能(以下、AI)や機械学習(machine learning： 以下、ML)を使
Profiling Python and Ruby using eBPF
tl;dr In our continued efforts to expand and improve your profiling experience, we are excited to announce new additions to our language support: Ruby and Python. All the features that are described in this blog post have recently been released as part v0.26.0 of Parca Agent. ~~While currently these language supports are in beta, they can be enabled using the --enable-ruby-unwinding and --enable-p
Why and How Does Python Use Bloom Filters in String Processing?
In our last discussion we learned all about bloom filters. It’s a unique data structure that provides membership queries in constant time while using a minimal quantity of memory. Primarily, you will find them being used in large scale and streaming applications where it is infeasible to keep all the data in memory. Examples include NoSQL databases, CDNs, load balancers, etc. However, it also has
Visualizing the CPython Release Process
Below are the high-level steps (with numbers corresponding to the above diagram) in the order they occur during the CPython release process: Freeze the python/cpython release branch. This is done using GitHub Branch Protections. Update the Release Manager's fork of python/cpython. Run Python release tools (release-tool, blurb, sphinx, etc). Push diffs and signed tag to Release Manager's fork. Git
Writing a C compiler in 500 lines of Python
A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog
PEP 703 - 兼雑記
https://peps.python.org/pep-0703/ Python の GIL 外す話。これすごく楽しい読みものでした。参照カウントのところが一番人気だと思うのですが、他のところも色々良い。こういう、「んーこういうことするとこういう問題が起きない？」と思ったら次の章くらいでそれが説明される、みたいな読みものは大変好きです 参照カウント: オブジェクトっていうのは作ったスレッドが解放するというのがほとんどなんだから、その場合はロックをいらなくする、他に渡ったら普通の参照カウントぽくする、という話。 Swift に 2018 年に導入された 話らしい。他のスレッドに渡された後で DECREF すると他スレッド用の参照カウントが負になりうるのだけど、その時に queue に入れるということをして、ややこしいので、なんかこれ無しですむ方法はないのかなぁ……と Immortalize
