Parallelizing Enjarify in Go and Rust
Last year, I rewrote Enjarify in Go and Rust in order to learn more about the languages and compare the difficulty, verbosity, performance, and error-proneness of the languages, and I wrote a post detailing my findings. For simplicity, I only measured single-threaded performance, but a number of commenters felt that this was unfair to Go because easy concurrency is one of the core selling points o
Announcing Linkerd 2.0
On behalf of the Linkerd maintainers, I’m happy to announce that Linkerd 2.0 is now in general availability (GA). This means that we’ve cut an official 2.0 stable release, and we think it’s ready for you to try in production. It’s already seeing the light of day at companies like WePay, Hush, Studyo, and JustFootball. You can try Linkerd 2.0 on a Kubernetes 1.9+ cluster in 60 seconds by running: (
Fixing the billion dollar mistake in Go by borrowing from Rust
panic: runtime error: invalid memory address or nil pointer dereference If you ever used Go, you probably saw this error at least once. Somewhere a nil pointer or nil interface was passed to a function that doesn’t handle nil. In all cases this is a programming error, either the function should hand…

Sloc Cloc and Code - What happened on the way to faster Cloc 2018/04/16 (11866 words) It started by wanting to write a code counter that would be faster than cloc. Update 2019-03-13 This is now part of a series of blog posts about scc Sloc Cloc and Code which has now been optimised to be the fastest code counter for almost every workload.

Why did we choose Rust over Golang or C/C++ to develop TiKV? | TiDB
What is Rust Rust is a systems programming language sponsored by Mozilla Research. It moves fast and steady with a 6-week release cycle ever since its 1.0 version in May 2015. See the following list for some of the features that most attract us: The design principles of Rust resemble with C++ in Abstraction without overhead and RAII (Resource acquisition is initialization). The minimum runtime and
Rust vs. Go
This post is a head-to-head comparison of Rust vs. Go for NTPsec’s purposes. Read it bearing in mind that the NTP codebase has an unusual combination of traits - not as hard-core a systems-programming problem as an OS kernel, but with some critical regions that are soft realtime. This is an outside view, written after I had programming experience in Go but before I had any in Rust. The Rust parts
My experience rewriting Enjarify in Rust
Last year I decided to rewrite Enjarify (a command line Python application) in Go and take notes in order to get data comparing the languages. Obviously, with a rewrite of an existing project, the resulting code won’t be as idiomatic as a project written from scratch, but I thought it was fair since Gophers are constantly trying to convert people away from Python for some reason, and doing a rewri
Async IO in Rust (part III)
This is the third article in series of articles about the design of Rotor, a library doing asynchronous IO in Rust. It has been about three months since my first article was published. And my first asynchronous code written in rust is almost a year old. That code still works in production (in a non-mission-critical role). This is to say that it’s time to stop rewriting rotor on every occasion and
Rust and Rest
Rust and Rest written on Sunday, July 10, 2016 A few months back I decided to write a command line client for Sentry because manually invoking the Sentry API for some common tasks (such as dsym or sourcemap management is just no fun). Given the choice of languages available I went with Rust. The reason for this is that I want people to be able to download a single executable that links everything

Navigating the Postmodern Python World
Navigating the Postmodern Python World If there is one defining feature of modern Python, it’s simply that is that the definition of Python itself is becoming increasingly blurred. Many projects over the last few years have taken larger and larger leaps to extend Python and reconstruct what “Python†itself means. At the same time on there are variety of technologies encroaching on Python’s niche,
