Stepping up for a truly open source Elasticsearch | Amazon Web Services
AWS Open Source Blog Stepping up for a truly open source Elasticsearch Last week, Elastic announced they will change their software licensing strategy, and will not release new versions of Elasticsearch and Kibana under the Apache License, Version 2.0 (ALv2). Instead, new versions of the software will be offered under the Elastic License (which limits how it can be used) or the Server Side Public
Should you use PyTorch vs TensorFlow in 2023? This guide walks through the major pros and cons of PyTorch vs TensorFlow, and how you can pick the right framework. PyTorch and TensorFlow are far and away the two most popular Deep Learning frameworks today. The debate over which framework is superior is a longstanding point of contentious debate, with each camp having its share of fervent supporters

ノーベル経済学賞を受賞したゴルディン博士の論文｜ゆきと
2023年のノーベル経済学賞は、ハーバード大学のクラウディア・ゴルディン博士に授与されました。 ノーベル経済学賞に男女間の格差是正など研究のゴールディン氏 「男女の賃金格差」という男女論ど真ん中の研究だったということで、ツイッター男女論界隈は大いに沸き立ったようです。 しかしながらその解釈は個々に異なっており、ツイッターではフェミニスト・反フェミニスト双方が「ノーベル賞受賞者がフェミニズム or アンチフェミニズムを支持した！」とでもいうように色めき立つという大混乱の様相を呈しております。（スクショ引用しようと思いましたが角が立ちそうなのでやめておきます。） しかし、何名かの識者が指摘しているように「テキスト」を読まずに物事を判断したり、批判したりするのは適切ではないでしょう。そこで今回は、このノーベル賞の対象となった研究がどのようなものであったか、またそこからどのようなことが考えられるか
How Airbnb ships features faster across web, iOS, and Android using a server-driven UI system named Ghost Platform 👻. By Ryan Brooks Background: Server-Driven UIBefore we dive into Airbnb’s implementation of server-driven UI (SDUI), it’s important to understand the general idea of SDUI and how it provides an advantage over traditional client-driven UI. In a traditional world, data is driven by th
Today we’re excited to announce the release of TypeScript 5.2! If you’re not familiar with TypeScript, it’s a language that builds on top of JavaScript by making it possible to declare and describe types. Writing types in our code allows us to explain intent and have other tools check our code to catch mistakes like typos, issues with null and undefined, and more. Types also power TypeScript’s edi
Companies Using RFCs or Design Docs and Examples of These
RFCs - requests for comment - or Design Docs are a common tool that engineering teams use to build software faster, by clarifying assumptions and circulating plans earlier. There are some similarities between writing automated tests for your code, and writing RFCs before you start working on a non-trivial project: Software engineers who write tests for their code - and ask for code reviews on it -

The Rust team is happy to announce a new version of Rust, 1.65.0. Rust is a programming language empowering everyone to build reliable and efficient software.

Testing sync at Dropbox
…and how we rewrote the heart of sync with confidence. Executing a full rewrite of the Dropbox sync engine was pretty daunting. (Read more about our goals and how we made the decision in our previous post here.) Doing so meant taking the engine that powers Dropbox on hundreds of millions of user’s machines and swapping it out mid-flight. To pull this off, we knew we would need a serious investment
Today we’re excited to announce our Release Candidate of TypeScript 5.2! Between now and the stable release of TypeScript 5.2, we expect no further changes apart from critical bug fixes.

Python’s “Type Hints” are a bit of a disappointment to me
2022-04-21 Preface You are reading version 2.0 of this blog post. Readers shared this link on Hacker News and lobsters, which unexpectedly blew up and sparked many heated discussions. I’ve incorporated some of this feedback into this revised version. (Some time later, there was also a discussion about this article on The Real Python Podcast.) Introduction Over the course of several Python 3.x vers
How Swift Achieved Dynamic Linking Where Rust Couldn't - Faultlore
How Swift Achieved Dynamic Linking Where Rust Couldn't For those who don’t follow Swift’s development, ABI stability has been one of its most ambitious projects and possibly it’s defining feature, and it finally shipped in Swift 5. The result is something I find endlessly fascinating, because I think Swift has pushed the notion of ABI stability farther than any language without much compromise. So
Coroutines and effects
For the past few months I’ve been mulling over some things that Russell Johnston made me realize about the relationship between effect systems and coroutines. You can read more of his thoughts on this subject here, but he made me realize that effect systems (like that found in Koka) and coroutines (like Rust’s async functions or generators) are in some ways isomorphic to one another. I’ve been pon
If you’ve been making websites for years, you know how frustrating it was to lay out a web page with CSS floats. Managing sizes and placement was tedious and time consuming. Being creative was often impossible. CSS Grid greatly eased that pain with Grid Level 1 in 2017, and now with Grid Level 2, aka Subgrid. But even with the powerful CSS of today, not every layout imaged by designers is possible
Several weeks ago, the .NET Blog featured a post What is .NET, and why should you choose it?.

Introduction Before explaining why I created Oil, let's review what it is. You can think of a Unix shell in two ways: As a text-based user interface. You communicate with the operating system by typing commands. As a language. It has variables, functions, and loops. Shell programs are text files that start with #!/bin/sh. In this document, we'll think of Unix shells as languages. The Oil project a
GitHub - aappleby/metroboy: A repository of gate-level simulators and tools for the original Game Boy.
GateBoy is a gate-level simulation of the original Game Boy hardware that was reverse-engineered from die shots of the original DMG-01 chip. It includes all the standard cells on the chip but not the CPU - it's made of custom logic and is a bit too blurry for me to decipher. GateBoy's CPU is instead my current best guess at how it might be implemented given the constraints implied by the rest of t
Text editors can be an interesting challenge to program. The types of problems that text editors need to solve can range from trivial to mind-bogglingly difficult. Recently, I have been on something of a spiritual journey to rework some internal data structures in an editor I have been building, specifically the most fundamental data structure to any text editor: the text.

Two years ago, Google proposed Manifest v3, a number of foundational changes to the Chrome extension framework. Many of these changes introduce new incompatibilities between Firefox and Chrome.

However, we will diverge from

Currently, Apache Kafka® uses Apache ZooKeeper™ to store its metadata. Data such as the location of partitions and the configuration of topics are stored outside of Kafka itself, in a separate ZooKeeper cluster. In 2019, we outlined a plan to break this dependency and bring metadata management into Kafka itself. So what is the problem with ZooKeeper? Actually, the problem is not with ZooKeeper its

Feedback from users of Mill is often surprisingly positive, with people saying it is "intuitive" or feels "jus
On Pair Programming
Teams are often reluctant to switch pairs, but what if we rotate pairs every day? We did an experiment with three teams and learned that pair swapping frequently greatly enhances the benefits of pairing. Here we share our experiment design so that others can experiment with rotation frequency. Rotating pairs means that after working together for some time, one half of the pair leaves the story, wh

The textbooks cover the same sweeping story, from the brutality of slavery to the struggle for civil rights.

But they are customized for students in different states, and their contents sometimes diverge in ways that reflect the na
