The Shape of Code » Software effort estimation is mostly fake research
Effort estimation is an important component of any project, software or otherwise. While effort estimation is something that everybody in industry is involved with on a regular basis, it is a niche topic in software engineering research. The problem is researcher attitude (e.g., they are unwilling to venture into the wilds of industry), which has stopped them acquiring the estimation data needed t
Pythonのlinter/formatterを誰でも手軽に設定できるようにするためのPFN社内ツール “pysen” の紹介 - Preferred Networks Research & Development
Home Blog Pythonのlinter/formatterを誰でも手軽に設定できるようにするためのPFN社内ツール “pysen” の紹介 Python向けのlinter/formatter設定ツール「pysen」を pypi.org および github.com で一般公開しました。 このツールは主にPython向けのlinter/formatterの設定を一元管理し、Preferred Networks社内でよく使われているツール環境を誰でも簡単に設定できるように支援するツールです。チームごとに分散しうるようなツールに関するノウハウをコードとして集約し、PFN社内での共有を促進させることを目的として開発しています。pysenは実際にPFN社内で使われており、2020年4月に開発がスタートしてから、2021年3月現在でおよそ100を超える社内リポジトリに導入されています。 上図:
Writing a Postgres SQL Pretty Printer in Rust: Part 1
This is the first of a planned series of blog posts about my pg-pretty project. I’ll cover some things I’ve learned about Rust and Postgres SQL, as well as some things I still don’t know.

A Year in the Life of a Compiler Fuzzing Campaign
By Alex Groce, Northern Arizona University In the summer of 2020, we described our work fuzzing the Solidity compiler, solc. So now we’d like to revisit this project, since fuzzing campaigns tend to “saturate,” finding fewer new results over time. Did Solidity fuzzing run out of gas? Is fuzzing a high-stakes project worthwhile, especially if it has its own active and effective fuzzing effort? The
An introduction to typeclass metaprogramming
Typeclass metaprogramming is a powerful technique available to Haskell programmers to automatically generate term-level code from static type information. It has been used to great effect in several popular Haskell libraries (such as the servant ecosystem), and it is the core mechanism used to implement generic programming via GHC generics. Despite this, remarkably little material exists that expl
The Solution of the Zodiac Killer’s 340-Character Cipher—Wolfram Blog
Editor’s note: The Zodiac Killer (an unidentified American serial killer active during the 1960s and 70s) sent numerous taunting letters to the press in the San Francisco area with regard to a local murder spree. In these letters, the killer took responsibility for the crimes and threatened to commit further murders. He also included three ciphers, each containing one-third of a 408-character cryp
Emoji under the hood
Emoji under the hood Translations: Chinese Russian For the past few weeks, I’ve been implementing emoji support for Skija.

A few well-known facts to get started: SQLite is the most common DBMS in the world, shipped with all popular operating systems.SQLite is serverless.For developers, SQLite is embedded directly into the app.For everyone else, there is
How to implement a hash table (in C)
March 2021 Summary: An explanation of how to implement a simple hash table data structure using the C programming language. I briefly demonstrate linear and binary search, and then design and implement a hash table. My goal is to show that hash table internals are not scary, but – within certain constraints – are easy enough to build from scratch. Go to: Linear search | Binary search | Hash tables

Laurence Tratt: Automatic Video Editing
Amongst the many consequences of COVID-19 has been the suspension of in-person talks: suddenly, people like me have had to think about how to produce prerecorded videos. In this article I’m going to explain what I’ve come to understand about video recording and the “automatic video editing” technique I’ve used for videos such as Virtual Machine Warmup Blows Hot and Cold. To give you an idea of how

Darker Corners of Go – Rytis Biel
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

A look back at asynchronous Rust
In 2013, I discovered the Rust programming language and quickly decided to learn it and make it my main programming language. In 2017, I moved to Berlin and joined Parity as a Rust developer. The task that occupied my first few months was to build rust-libp2p, a peer-to-peer library in asynchronous Rust (~89k lines of code at the moment). Afterwards, I integrated it in Substrate (~400k lines of co
Release of Oil 0.8.8
This is the first release in almost two months! I'm writing a blog post that gives color on this (#project-updates), but let's do the usual release announcement first. Most of the work done was under the hood, with major progress on the garbage collector (previously) and build system. I also do a thorough review of project #metrics in the appendix.
