어쩔때는 Zed가 좋은 것 같은데, 어쩔 때는 Neovim이 좋음. 수제코딩할때 Zed랑 Neovim이랑 아등바등하게 괜찮은데, 빠릿빠릿하고 에디터 환경에 대한 제어권이 온전히 나에게 있는 것을 꼽자면 Neovim. 플러그인이 사실상 0인데, 있을 것들은 다 들어가 있고 수제로 코딩하는 맛이 타격감이 괜찮은건 Vim 모드가 가미된 Zed.... 프로젝트를 할 때는 Neovim을 주로 쓰기는 하지만, 학습할때는 Zed를 쓰는 빈도가 좀 있는 듯.

지금 만들고 있는 NestJS 기반의 연합우주 앱도 의도적으로 Zed로 수제코딩 하고 있음. 퐝션? 그런거 쓰지 마세요

We'd like to recognize some excellent contributions from our (Open Source Contribution Academy) participants who have been working on .

@gaebalgom개발곰 contributed PR #339, which introduces the @fedify/elysia package to provide Elysia integration for Fedify. This work addresses issue #286 by creating a plugin that enables developers using and to integrate Fedify's capabilities into their applications. The contribution includes the core integration module, documentation, examples, and proper monorepo configuration, making Fedify accessible to the Elysia community.

@r4bb1t submitted PR #315, implementing comprehensive AbortSignal support across multiple APIs to resolve issue #51. This contribution adds request cancellation capabilities not only to lookupWebFinger() but also to lookupObject(), DocumentLoader, and the HTTP signature authentication flow (doubleKnock()), allowing developers to properly handle timeouts and abort ongoing requests throughout the entire request chain. The implementation includes extensive test coverage for cancellation scenarios across all affected components and lays the groundwork for adding --timeout options to various CLI commands like fedify lookup, fedify webfinger, and fedify nodeinfo, making federated applications more robust and responsive.

@ooheundaoed addressed a testing infrastructure issue with PR #350, fixing a race condition in PostgreSQL message queue tests that was causing intermittent failures (issue #346). By adding explicit initialization before concurrent message queue listeners, this fix prevents table creation conflicts that were affecting test reliability, ensuring more consistent PR testing for all contributors.

@songbirds provided two test stability improvements with PR #344 and PR #347. The first PR adds skip guards to RedisKvStore tests as a workaround for a known Bun runtime issue, keeping the test suite functional while awaiting an upstream fix. The second PR resolves a race condition in the code generation process by randomizing output filenames, preventing conflicts during parallel test execution. These contributions help maintain a stable testing environment for the project.

Thank you all for your contributions to Fedify. Your work helps make federated social networking more accessible to developers.

전 개인적으로 LINQPad를 정말 좋아하는데요, LINQPad 9 Beta 버전에서 새롭게 강화된 JavaScript Interop과 내장된 WebView 지원 덕에 C# 코드 레벨에서 ESM 모듈을 불러와 사용하는 것도 훌륭하게 소화 가능합니다. 이 코드는 LINQPad 밖에서는 WebView2를 대상으로도 쓸 수 있습니다.

LINQPad 9의 내장 자바스크립트 엔진으로 ESM 모듈 사용하기

LINQPad가 본격적으로 크로스플랫폼 지원을 위해서 Chromium 기반 웹 뷰를 전환한 이후 크게 개선된 부분으로, JavaScript 코드를 C# 컨텍스트에서 실행할 수 있게 된 점이 매우 유용합니다. 이 점을 활용해서 아래 스크린 샷처럼 ESM 모듈을 불러와서 테스트하는 것까지 시도해볼 수 있어서 매우 흥미롭습니다. 😃 아래 코드를 붙여 넣고, 웹 뷰를 연 다음 Ctrl+Shift+I (macOS의 경우 Cmd+Shift+I)로 Developer Tool을 띄우면 웹 브라우저 측 콘솔의 로그를 실시간으로 볼 수 있습니다. var script = """ import _ from 'https://cdn.jsdelivr.net/npm/lodash-es@4.17.21/lodash.min.js'; console.log(_.map([1, 2, 3], x => x * 10)); """; Util.JS.Run($$""" const script = document.c...

OSTEP 독학 일지 - H.0.

Jaeyeol Lee @kodingwarrior@hackers.pub

6년 차 개발자가 기본기를 다지기 위해 OS 기초를 다시 공부하는 여정을 담은 글입니다. 저자는 신입 개발자 수준의 기본기를 갖추기 위해 OSTEP 교재를 선택하고, xv6 프로젝트를 통해 운영체제 동작 원리를 체화하고자 합니다. 이 글에서는 xv6 과제들을 단계별로 공략하며 겪는 우여곡절과 발견, 그리고 이를 통해 얻는 인사이트를 서사적으로 풀어낼 계획을 밝힙니다. 단순히 지식을 정리하는 것을 넘어, 독자에게 재미있는 스토리를 전달하고 기술 면접에도 도움이 될 만한 생생한 경험을 공유하고자 하는 저자의 의지가 돋보입니다. OSSCA 2025 멘토링 경험에서 영감을 받아 시작된 이 여정은, 개발자로서의 성장과 더불어 해커스펍 커뮤니티에도 기여하고자 하는 저자의 열정을 보여줍니다.

2004年8月5日から始まったエンジニア人生、気づけばもう21年。本当にお疲れ様、21年間の自分。

  • すべてが素晴らしかった会社もあった。
  • 恨みや憎しみでいっぱいだった職場もあった。
  • 良いところも悪いところもあった会社。
  • 給料も退職金も払わなかったひどい会社。
  • ちょっと変わった会社もあったな…。
  • 本当に色々あった、波乱万丈の21年だった。

これからの10年も、自分自身にエールを送りながら――
すべてが思い通りにいくわけじゃないけれど、そんな時こそ、逃げずに、正面からぶつかって、前に進む覚悟で。

Fedify: ActivityPub server framework @fedify@hollo.social
Public
Shared by 洪 民憙 (Hong Minhee)

We're thrilled to highlight five outstanding contributions from the Korean Open Source Contribution Academy () program participants who have been working on ! Their dedication and effort have significantly enhanced our server framework.

First up is @nyeongAn Nyeong (安寧) with his monumental #318 PR, implementing a SQLite-based key–value store to address #274. This contribution adds the SqliteKvStore class with full cross-runtime support for Node.js, Deno, and Bun through the new @fedify/sqlite package. His implementation includes atomic operations, TTL support, comprehensive test coverage, and careful attention to SQL injection prevention. This enables developers to use SQLite as a persistent storage backend while maintaining compatibility with Fedify's existing KvStore API—a crucial feature for production deployments!

Next, @crohasang크롸상 delivered an excellent quality-of-life improvement with #341 PR, fixing #257. He enhanced the CLI to properly respect TTY status and the NO_COLOR environment variable, implementing intelligent color control across all CLI commands. The solution involved switching from @cliffy/ansi/colors to @std/fmt/colors, creating a helper function using Deno.inspect() to handle object formatting, and ensuring colors are correctly disabled when output is redirected to files. This makes the CLI much more pipe-friendly and suitable for automated workflows!

@meneleHanal Ae contributed a thoughtful enhancement with #342 PR, addressing #191. She updated the fedify inbox command to display not just the activity type, but also the type of object contained within each activity—transforming output like "Create" into the more informative "Create(Note)" or "Undo" into "Undo(Follow)". This seemingly simple change required making the display function asynchronous to fetch the enclosed objects, significantly improving the debugging experience for developers!

@woaol벨 tackled an important developer experience issue with #329 PR, solving #306. Previously, the fedify init command would often install outdated versions of Fedify packages like @fedify/redis because version numbers were hardcoded in the CLI. They created a getLatestVersion() function that dynamically retrieves package versions from local metadata files, ensuring that developers always get the latest versions of all Fedify packages when initializing a new project. This improvement includes comprehensive test coverage and eliminates the frustration of starting a project with outdated dependencies!

Finally, @kodingwarriorJaeyeol Lee made a significant contribution with #309 PR, implementing #269—NestJS integration! They created the @fedify/nestjs package with a FedifyModule that seamlessly integrates Fedify into NestJS applications. This includes proper middleware implementation, dependency injection support through NestJS's module system, and compatibility with both CommonJS and ESM environments. This opens up Fedify to the large NestJS developer community, making it easier than ever to build ActivityPub-enabled applications with this popular enterprise framework!

These contributions showcase the incredible talent and dedication of the OSSCA participants. From core infrastructure improvements to developer experience enhancements, each contribution makes Fedify better for the entire community. Thank you all for your hard work and welcome to the Fedify contributor family! 🚀

We're looking forward to seeing more amazing contributions from the OSSCA program and the broader community. If you're interested in contributing to Fedify, check out our GitHub repository and join us in building the future of federated social web! 🌟
