Introducing Danfo.js, a Pandas-like Library in JavaScript
A guest post by Rising Odegua, Independent Researcher; Stephen Oni, Data Science Nigeria Danfo.js is an open-source JavaScript library that provides high-performance, intuitive, and easy-to-use data structures for manipulating and processing structured data. Danfo.js is heavily inspired by the Python Pandas library and provides a similar interface/API. This means that users familiar with the Panda
「Pulumi」がバージョン1.0に到達、正式版に。インフラの状態をJavaScript、Python、Goなどで記述可能。個人向けサービスは無料で提供
「Pulumi」がバージョン1.0に到達、正式版に。インフラの状態をJavaScript、Python、Goなどで記述可能。個人向けサービスは無料で提供 かつてサーバの設定や起動、ネットワークの構成といったインフラの構築は、それぞれの設定ツールやコンソールから運用担当者がマニュアル操作で行ってきました（いまでもそうしている組織は少なくないでしょう）。 しかし仮想化基盤やクラウドなど最近のモダンなインフラでは、APIや設定ファイルを通じてプロビジョニングやコンフィグレーションが可能です。 このようにソフトウェアでインフラの状態の表現が可能になることを、いわゆる「Infrastructure as Code」（コードとしてのインフラ）と呼びます。 Infrastructure as Codeの利点は、インフラの状態をコードで記述することによって、誰でも確実に間違いなく実行できて手作業によるミス
It’s not wrong that "🤦🏼♂️".length == 7
The string that contains one graphical unit consists of 5 Unicode scalar values. First, there’s a base character that means a person face palming. By default, the person would have a cartoonish yellow color. The next character is an emoji skintone modifier the changes the color of the person’s skin (and, in practice, also the color of the person’s hair). By default, the gender of the person is und
ORMs are backwards
ORMs are something that seem cool until you have to do anything with them, and then they just get in the way. Their promises (backend-agnostic, write type-safe native code, less boilerplate) sometimes have a catch and sometimes are just false. The reason for this is that ORMs are backwards: they force you to design schemas in your implementation language (python, javascript, java) and then export

JavaScript: The Modern Parts
In the last few months, I have learned a lot about modern JavaScript and CSS development with a local toolchain powered by Node 8, Webpack 4, and Babel 7. As part of that, I am doing my second “re-introduction to JavaScript”. I first learned JS in 1998. Then relearned it from scratch in 2008, in the era of “The Good Parts”, Firebug, jQuery, IE6-compatibility, and eventually the then-fledgling Node
WebAssembly Interface Types: Interoperate with All the Things! – Mozilla Hacks - the Web developer blog
WebAssembly Interface Types: Interoperate with All the Things! People are excited about running WebAssembly outside the browser. That excitement isn’t just about WebAssembly running in its own standalone runtime. People are also excited about running WebAssembly from languages like Python, Ruby, and Rust. Why would you want to do that? A few reasons: Make “native” modules less complicated Runtimes
Static Analysis at Scale: An Instagram Story
Instagram Server is entirely Python powered. Well, mostly. There’s also some Cython, and our dependencies include a fair amount of C++ code exposed to Python as C extensions. Our server app is a monolith, one big codebase of several million lines and a few thousand Django endpoints [1], all loaded up and served together. A few services have been split out of the monolith, but we don’t have any pla
Compiling dynamic programming languages | notes.eatonphil.com
It can be difficult to disassociate the idea that dynamically typed programming languages are tied to byte-code interpreters (e.g. YARV Ruby, CPython, V8, Zend Engine, etc.). But for many languages, a compiled implementation also exists. Cython, Chicken Scheme and SBCL are good examples. In this post I will briefly describe how I built a compiler for my Scheme implementation using artifacts from t
How JavaScript works: Parsing, Abstract Syntax Trees (ASTs) + 5 tips on how to minimize parse time
This is post # 14 of the series dedicated to exploring JavaScript and its building components. In the process of identifying and describing the core elements, we also share some rules of thumb we use when building SessionStack, a JavaScript tool for developers to identify, visualize, and reproduce web app bugs through pixel-perfect session replay.
