Rewriting the Ruby parser
At Shopify, we have spent the last year writing a new Ruby parser, which we’ve called YARP (Yet Another Ruby Parser). As of the date of this post, YARP can parse a semantically equivalent syntax tree to Ruby 3.3 on every Ruby file in Shopify’s main codebase, GitHub’s main codebase, CRuby, and the 100 most popular gems downloaded from rubygems.org. We recently got approval to merge this work into C

Kubernetes HPA External Metrics を利用した Scheduled-Scaling - スタディサプリ Product Team Blog
こんにちは。SRE の @chaspy です。 Quipper では Kubernetes Horizontal Pod Autoscaler (以下、HPA) を利用して Pod のオートスケーリングを実現しています。 HPA は非常に便利で、ほとんどのトラフィック増減に対応できます。しかし、オートスケーリングの宿命ではありますが、突発的なアクセス、いわゆるスパイクアクセスにはどうしても対応できません。CPU 利用率が急激に上がり、HPA がすぐに Desired Replicas を増やしたとしても、Node*1 のスケールアウトに5分程度はかかってしまいます。 CPU 使用率に基づくオートスケーリングに対して、決まった時間に決まった個数を事前にスケールしておくことを Scheduled-Scaling と呼ぶことにしましょう。前者のオートスケーリングと併用して Scheduled-S
Introduction to Go 1.17 The latest Go release, version 1.17, arrives six months after Go 1.16. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before. Changes to the language Go 1.17 includes three small enhancements to the l

Go 1.20 Cryptography
The first second release candidate of Go 1.20 is out!1 This is the first release I participated in as an independent maintainer, after leaving Google to become a professional Open Source maintainer. (By the way, that’s going great, and I’m going to write more about it here soon!) I’m pretty happy with the work that’s landing in it. There are both exciting new APIs, and invisible deep backend impro
[Protocol Buffers (Protobuf) is Google’s language-neutral data interchange format. See protobuf.dev.] Back in March 2020, we released the google.golang.org/protobuf module, a major overhaul of the Go Protobuf API. This package introduced first-class support for reflection, a dynamicpb implementation and the protocmp package for easier testing. That release introduced a new protobuf module with a n
Introduction to Go 1.20 The latest Go release, version 1.20, arrives six months after Go 1.19. Most of its changes are in the implementation of the toolchain, runtime, and libraries.

Note: this article is available as an ebook and as a printed book for easier reading Introduction What is this? When I was first learning Go, I already knew several other programming languages. But after reading an introductory book and the language specification I felt like I really didn’t know enough about Go to use it for real world work. I felt I’d probably need to fall into many traps before
Introduction to Go 1.19 The latest Go release, version 1.19, arrives five months after Go 1.18. Most of its changes are in the implementation of the toolchain, runtime, and libraries.

How does Go calculate len()..?
The impetus for this post was a question on the Gophers Slack a while back. A fellow developer wanted to know where to find more information on len. I want to know how the len func gets called. People chimed in quickly with a correct answer It doesn’t. Len is compiler magic, not an actual function call. … all the types len works on have the same header format, the compiler just treats the object l

An introduction to Handlers and Servemuxes in Go - Alex Edwards
Confused about Go's request handling? My book guides you through the start-to-finish build of a real world web application in Go — putting servers, handlers and servemuxes into context and covering topics like how to structure your code, create dynamic database-driven pages, and how to authenticate and authorize users securely. Take a look! Processing HTTP requests with Go is primarily about two t

pow-captcha
💥PoW! Captcha A proof of work based captcha similar to mCaptcha. Compared to mainstream captchas like recaptcha, hcaptcha, friendlycaptcha, this one is better for a few reasons: It is lightweight & all dependencies are included; total front-end unminified gzipped file size is about 50KB. It is self-hosted. It does not spy on you or your users; you can tell because you run it on your own server, y
research!rsc: Hash-Based Bisect Debugging in Compilers and Runtimes
Setting the Stage Does this sound familar? You make a change to a library to optimize its performance or clean up technical debt or fix a bug, only to get a bug report: some very large, incomprehensibly opaque test is now failing. Or you add a new compiler optimization with a similar result. Now you have a major debugging job in an unfamiliar code base. What if I told you that a magic wand exists
Django for Startup Founders: A better software architecture for SaaS startups and consumer apps
In an ideal world, startups would be easy. We'd run our idea by some potential customers, build the product, and then immediately ride that sweet exponential growth curve off into early retirement. Of course it doesn't actually work like that. Not even a little. In real life, even startups that go on to become billion-dollar companies typically go through phases like: Having little or no growth fo
