November 1, 2023 Hello! I’m slowly working on explaining git. One of my biggest problems is that after almost 15 years of using git, I’ve become very used to git’s idiosyncracies and it’s easy for me to forget what’s confusing about it. So I asked people on Mastodon: what git jargon do you find confusing? thinking of writing a blog post that explains some of git’s weirder terminology: “detached HE
Menu. Currently selected: Queueing a pull request to merge Today we are announcing the public beta of pull request merge queue for repos on GitHub Enterprise Cloud and open source organizations! 🎉 Merge queue helps increase velocity in software delivery by automating pull request merges into your busiest branches. Before merge queue, developers were often required to update their pull request bra
Code improves with multiple reviews and revisions, and this process isn’t something that can be done alone. Spotting errors in code design is difficult at the best of times — and the closer you are to the work, the harder it can be to critique. That’s where code reviews come in. The beginning: introducing code reviewsWhat is a code review? Code improves with multiple reviews and revisions, and thi
One of the most impactful things we’ve worked on in TypeScript 5.0 isn’t a feature, a bug fix, or a data structure optimization. Instead, it’s an infrastructure change. In TypeScript 5.0, we restructured our entire codebase to use ECMAScript modules, and switched to a newer emit target. What to Know Now, before we dive in, we want to set expectations. It’s good to know what this does and doesn’t m
Flutterアプリの定期リリースを支える自動化 - Fast DOCTOR Technologies TECH BLOG
本稿では、ファストドクターのモバイルアプリのリリースフローを整備した取り組みについてご紹介します。 モチベーション ファストドクターのモバイルアプリは、2022年夏にFlutterでのフルリプレースを実施し、それ以降は機能の開発が完了次第随時リリースをするという戦略を取っていました。 この戦略はシンプルであり、開発に関わっているステークホルダーが少ない状況下でうまく機能していました。しかし、組織の拡大に伴い以下のような問題が発生するようになりました。 複数機能の開発スケジュールの調整をしたり、バックエンドのリリース・QAとの整合性を取ったりという必要性が増し、調整コストが肥大化 リリースが不定期なため、いつPull Requestをマージすれば良いか分からずopenされたままのPull Requestが多数 この状況を改善するために、以下の要件を念頭に定期的なリリースとそれを支える仕組みを
ROUTE06 Software Engineerの@yoshida-m-3です。 GitHubからの通知が溢れ返る😂 GitHubはIssue、Pull Request、Projects、Actions、Discussionなど様々な機能があるため、通知の件数も増えていきます。 大量の通知をコントロールして効率良くチェックできるようにしましょう！ 不要な通知は受け取らないようにする🚫 そもそも本当に全て通知を受け取る必要はあるでしょうか？ クリック1つで情報へアクセス出来るので見てしまいますが、人一人が扱える情報量にも限度があります。 勇気を持ってWatched repositoriesから不要なRepositoryのWatchを外して通知自体を減らしてしまいましょう。 また、用件がある場合はMentionされるのでWatchして居ないRepositoryでも通知は届きます。 通知を

Today we excited to announce the availability of TypeScript 5.7! If you’re not familiar with TypeScript, it’s a language that builds on JavaScript by adding syntax for type declarations and annotations. This syntax can be used by the TypeScript compiler to type-check our code, and it can also be erased to emit clean, idiomatic JavaScript code. Type-checking is helpful because it can catch bugs in

Agentic GraphRAG for Commercial Contracts | Towards Data Science
In every business, legal contracts are foundational documents that define the relationships, obligations, and responsibilities between parties. Whether it’s a partnership agreement, an NDA, or a supplier contract, these documents often contain critical information that drives decision-making, risk management, and compliance. However, navigating and extracting insights from these contracts can be a
What Comes After Git
Git was born from the collaboration problems in the Linux kernel. Nearly a decade later, new problems arose when Kubernetes (the operating system of the cloud) brought open-source collaboration to a new level. I saw the pain points of git (and GitHub) firsthand working on Kubernetes open-source. Will a new version control system (or something that solves similar problems) spring up? Some ideas on
It’s been about 6 weeks since I joined Tano, and this is what my commit history looks like: Commits are a terrible metric for output, but they’re the most visible signal I have. Something real changed in how I work, and the commit count is a side effect. So, what has changed? Automating the grunt work When I joined Tano, I was making every pull request by hand.

Our vision is to evolve GitHub Copilot into an ecosystem of agents that collaborate across the entire development lifecycle from coding and code review to security, debugging, deployment, and maintenance.

Local-first software: You own your data, in spite of the cloud
Cloud apps like Google Docs and Trello are popular because they enable real-time collaboration with colleagues, and they make it easy for us to access our work from all of our devices. However, by centralizing data storage on servers, cloud apps also take away ownership and agency from users. If a service shuts down, the software stops functioning, and data created with that software is lost. In t

Teams at GitHub, Adobe, BBC, and many others use Storybook because it streamlines your frontend workflow. You write stories for granular UI states and then use them to verify component appearance during development. From there, you can reuse stories to run snapshot, visual, and accessibility tests during QA. Storybook can even analyze stories to auto-generate documentation. Storybook 6.5 is our bi

Trust Is the Bottleneck
Everyone is asking the same question now: if AI can help us create much more code, why aren’t engineering teams suddenly moving much faster? I think the question is right, but the answer usually stops too early. AI does make some things dramatically faster. MVPs are faster. Prototypes are faster. The time to validate an idea is reduced a lot. You can explore directions that previously weren’t wort
FoundationDB: A Distributed Key-Value Store – Communications of the ACM

FoundationDB adopts an unbundled architecture that decouples an in-memory transaction management system, a distributed storage system, and a built-in distributed configurati
Convert the codebase to modules by jakebailey · Pull Request #51387 · microsoft/TypeScript
(Or, wait until the next nightly after this is merged.) How? The bulk of the work to convert the repo to modules is done via automation, followed by a load of changes by hand to completely restructure our build system. To see the conversion process, take a look at the commits in this PR, each of which come with their own descriptive commit message. In short, the typeformer project recreates our ol

Merging two GitHub repositories without losing commit history – Mozilla Hacks - the Web developer blog
Merging two GitHub repositories without losing commit history We are in the process of merging smaller example code repositories into larger parent repositories on the MDN Web Docs project. While we thought that copying the files from one repository into the new one would lose commit history, we felt that this might be an OK strategy. After all, we are not deleting the old repository but archiving
