Rust で Erlang 処理系を実装してみている
今年の 9 月あたりから、 Rust で Erlang の処理系を実装してみています。まともに試せるほど進んでないんですが、気分的に年内に一区切りつけたいので公開しておきます。リポジトリはこちら。 https://github.com/szktty/starlight みています、というのはもちろん思いつきだからです。なにぶん Erlang は適用分野がベリーハードなミッションクリティカルシステムしかなく、あらゆる性能やメリットが Erlang VM (BEAM) を超えなければ非公式処理系の用途はありません。 かといって最初から諦めてもいませんが、業務で Erlang に関わらなくなったら or 開発に疲れたら自然消滅すると思います。すでにわりと疲れている。 進捗状況「速くなるのか？」「軽量プロセスは？」などの疑問に興味津々の皆様、すいません。全然ご期待に応えられません。本当に同梱のごく
The Erlang Runtime System
This book is not about how to write correct and beautiful code, I am assuming that you already know how to do that. This book isn’t really about profiling and performance tuning either. Although, there is a chapter in this book on tracing and profiling which can help you find bottlenecks and unnecessary usage of resources. There also is a chapter on performance tuning. These two chapters are the l

Erlang Garbage Collection Details and Why It Matters - Hamidreza Soleimani's Blog
24 Aug 2015 on erlang garbage collection memory layout soft realtime Erlang Garbage Collection Details and Why It Matters One of the main problems that Erlang tried to solve was creating a platform for implementing Soft Realtime systems with a high level of responsiveness. Such systems require a fast Garbage Collection mechanism that doesn’t stop the system from responding in a timely manner. On o
The Zen of Erlang
This is a loose transcript (or long paraphrasing?) of a presentation given at ConnectDev'16, a conference organized by Genetec in which I was invited to speak. I assume most people here have never used Erlang, have possibly heard of it, maybe just the name. As such, this presentation will only cover the high level concepts of Erlang, in such a way that it may be useful to you in your work or side
The Road to 2 Million Websocket Connections in Phoenix - Phoenix Blog
The Road to 2 Million Websocket Connections in Phoenix Posted on November 3rd, 2015 by Gary Rennie If you have been paying attention on Twitter recently, you have likely seen some increasing numbers regarding the number of simultaneous connections the Phoenix web framework can handle. This post documents some of the techniques used to perform the benchmarks. How It Started A couple of weeks ago I
Chat Service Architecture: Servers
League of Legends players collectively send millions of messages every day. They're asking friends to duo-queue, suggesting a team comp on the champ select screen, and thanking opponents for a good game. On July 21st of this year (I picked a day at random), players forged 1.7 million new friendships in the game—that’s a lot of love! And each time players send a message they trigger a number of ope
Erlang master classses - School of Computing - University of Kent
Erlang master classes These three Master Classes in Erlang will show you how Erlang can be used in practice to solve larger problems. We have chosen to give examples that provide 'capstones' for different aspects of Erlang: functional programming, concurrent programming and larger-scale programming with OTP. The master classes are presented by Joe Armstrong, Ericsson AB and KTH, Stockholm, and one

barrel - Distributed Database for the modern world
A P2P document-oriented database with modern features. Barrel is a modern document-oriented database in Erlang focusing on data locality (put/match the data next to you) and P2P. Barrel must also be able to work in unreliable conditions were sometimes the quorum can't be achieved (because it is working offline or in other conditions). Because Barrel is built on an existing relatively small code ba

Cowboy and Batman.js for Erlang Web Development · Erlware Blog
Why Cowboy and Batman.js There are a lot of Erlang web frameworks out there today. Not all are modeled after the MVC model (see Nitrogen), but I think all of them are addressing the problem the wrong way. I recently gave a presentation, slides here and the code for this example here, describing my perferred method for using Erlang for web development and why I think it is the best way to go. In th
