Babel が Flow から TypeScript に移行した
先日 Babel のメンテナーとして知られる Nicolò Ribaudo 氏が次のツイートを投稿した。 We finally finished migrating the Babel monorepo from Flow to TypeScript! It has been a very long process started by @z_bodya, and after migrating package-by-package @JLHwung just opened this PR 😄 pic.twitter.com/WKXxV8x2MY — Nicolò Ribaudo 🏳️🌈 • 💙💛 (@NicoloRibaudo) July 23, 2022 そう、JavaScript のトランスコンパイラである Babel のソースコードが Flow から TypeScrip
Elixir Flowでlazyな並列分散処理 - Qiita
Flowとは GenStageのWrapper. 普段コレクションを操作する時に使うEnumっぽいインターフェースなので親しみやすい. YoutubeにElixir作者のJoséの解説が上がっている. https://www.youtube.com/watch?v=srtMWzyqdp8&feature=youtu.be&t=244 GenStageとは コレクションをlazyかつ並列分散処理出来るElixirのbehaviour. AkkaのBack-Pressureなどに影響された. Back-Pressureとは 要求ドリブン(demand-driven)でデータの生成主体(producer), 消費主体(consumer)間で、cosumerの要求に従ってproducerがデータを渡すことでデータの流量を調節する仕組み。ConsumerはFlowを使うことでstageとして並列に並
The Token Approach for Architecting Flow in Elixir · rrrene
The Token Approach for Architecting Flow in Elixir 30 Apr 2018 // posted in Architecting Flow in Elixir In the last two posts we looked at the Token approach and how we can leverage metaprogramming to build pipelines and custom DSLs processing this Token. The Tokenis just a struct holding relevant data for the execution of your program: # This struct is handed down during the execution of your pro

Using Metaprogramming for Architecting Flow in Elixir 09 Apr 2018 // posted in Architecting Flow in Elixir TL;DR You can adapt the ideas presented in the last article to any kind of application. Macros can be used to build a Plug-like DSL for your specific use-case. But be careful: Use metaprogramming wisely and only where it’s a good fit. Do not try to build the “Plug for everything”. In the last

There is, however, a third concept to model flow in your applications: to hand down a “token” during the execution of your program. This token contains all the information necessary for yo

Photography Phoenix GenStage & Flow GeoCoding Personal Cloud When I first heard about GenStage and Flow my thought was to use it in a photo processing project that I had on the backburner. With so many photos to manage, and not just digital pictures, but scans, original art as well as older digital photos with sketchy data attached. I’ve never been happy with the organizing tools available in the
初心者のElixir |> Flow,GenStage |> Concurrent MapReduce - Qiita
When 2017/04/01 At Elixir Conf Japan 2017 LT Self Introduction ちきさん (Tomohiro Noguchi) Twitter/GitHub/Qiita: @ovrmrw I've started to learn Elixir 1 month ago. What I talk about Reading a JSON file and doing MapReduce. (JSONファイルを読み込んでMapReduceしたい。) Differences between Eager, Lazy and Flow(Concurrent). (Eager, Lazy, Flow(Concurrent)の違いについて。) Flow & GenStage is extremely fast. (Flowめちゃくちゃ速い。) === Git
Architecting Flow in Elixir Programs: An Introduction · rrrene
Architecting Flow in Elixir Programs: An Introduction 30 Jan 2018 // posted in Architecting Flow in Elixir Getting the “flow” of a program is one of the first things I do when looking at open source software or joining a new project at work. The easier it is to grasp how data flows through a program, the easier it is for me as a developer to estimate the impact of changes (and the business of soft
Quaff that potion: saving $millions with Elixir and Erlang - NextRoll
We slashed our DynamoDB costs by over 75% using Kinesis, DynamoDB streams, and Erlang/OTP (and now Elixir) to implement a global cache warming system. We present that system and two new open-source libraries for processing Kinesis and DynamoDB streams in a similar way using Elixir and Erlang. 15-20 minute read AdRoll uses Erlang/OTP as the basis for several internal products, including a real-time
Relicensing React, Jest, Flow, and Immutable.js
Next week, we are going to relicense our open source projects React, Jest, Flow, and Immutable.js under the MIT license. We’re relicensing these projects because React is the foundation of a broad ecosystem of open source software for the web, and we don’t want to hold back forward progress for nontechnical reasons. This decision comes after several weeks of disappointment and uncertainty for our

Designing a P2P Lending platform with Elixir in mind
With this post, I want to share with you the design process on one of our latest projects — a P2P marketplace that was intended to be used by one of largest online lenders and all kinds of investors for securitization of their portfolios. And almost insane stack change that turned out to be a great idea. Why? To attract new engineers and backers to Elixir community. I do not consider myself an ent
