私がこれを書く動機 私はKaigi on Railsのオーガナイザーのひとりです。Kaigi on Rails 2023は物理会場にて開催されることが公開されました。そうなるともちろん、会場でのインターネットについてはどうなる、どうする、という問題が出てきます。それに備えて、先輩イベントであるRubyKaigiを参考にしようというわけで、自分の理解のために書くことにしました。 おことわり 私はRubyKaigi 2022のネットワークをお手伝いしましたが、ケーブルの巻き直し、APの設営、撤収時の諸々を手伝ったのみです。よってこれから言及する内容については、一般参加者に毛が生えた程度の事前知識しかありません。 またこれから読み解くコードにおいて、コメントする内容の正確性は一切ないものと思って読んでください。 RubyKaigiのネットワークについて RubyKaigiのネットワークにおけるL

【開発】スカッシュマージを卒業しプロダクトを加速させるブランチ戦略へ | SocialDog Tech Blog
こんにちは！ 8月からSocialDogにジョインしたあっきーこと上田です！現在はチームリーダーとしてSocialDogの新規開発を仲間たちと励んでいます！開発たのしい〜〜〜！！ ところで私はgitが大好きです。なぜ好きなのかを語るとこの記事が終わらないので割愛しますが、 SocialDogにジョインした後、なんと早速gitの運用変更に携わったので、その経緯や何をしたか、またおまけとしてマニアックなgitの活用方法について紹介していきます！ スカッシュマージとそのメリットSocialDogでは以下の目的から2年ほどでプルリクエストをスカッシュマージで運用していました。 次のようなメリットがあるためです。 1トピック1コミットになるプルリクエストがマージされたときにコミットが1つになるため、流れが追いやすくなります。 つまりgitのログ検索の操作でハマる時間の削減ができます。 コミットを作る

11th March 2025 Online discussions about using Large Language Models to help write code inevitably produce comments from developers who’s experiences have been disappointing. They often ask what they’re doing wrong—how come some people are reporting such great results when their own experiments have proved lacking? Using LLMs to write code is difficult and unintuitive. It takes significant effort
Making a Chess Engine in Zig
I had the honor of speaking at Systems Distributed at the end of June. Since it was hosted by TigerBeetle who is one of the largest zig users, a lot of the zig community was there. After talking to some of them, Zig seemed more interesting for me to try out. Around the same time my youtube algorithm got me hooked on chess content. I’m not a good chess player by any means, but it started giving me

はじめましての方ははじめまして。ピクシブで Scala エンジニアとして働いている Javakky です。 今回はビルド高速化 / デプロイの利便化のためビルド環境を Jenkins から GitLab に移行しましたので、そのレポートをお送りしていきたいと思います。 弊社のデプロイについて まずは、弊チームリポジトリの動作環境とデプロイの流れがどうなっていたかを見ていきます。 弊チームの利用する環境としては、本番環境 (サーバー)、ステージング環境 (サーバー)、共用開発環境 (サーバー)、個人用開発環境 (ローカル) の 4種類が存在します。厳密にはバッチ処理をするサーバーも存在するのですが、デプロイ時には本番環境と全く同時にデプロイしているため、ここでは本番環境に含めることにします。 個人用開発環境でのプログラムの起動は sbt run コマンドで行っているのですが、その他サーバー上
Adopting Wide Event-style instrumentation has been one of the highest-leverage changes I've made in my engineering career. The feedback loop on all my changes tightened and debugging systems became so much easier. Systems that were scary to work on suddenly seemed a lot more manageable. Lately there have been a lot of good blog posts on what "Wide Events" mean and why they are important. Here are

CircleCI 60% faster builds: use Xcode DerivedData for caching!
When working on large projects you have to constantly take care of the CI and build time condition, especially when you time have more than 5 members. In team where i am currently working we reach the point where our current app build time take 25 minutes. We were thinking how we could reduce build time and CI maintenance cost. The main idea was to cache DerivedData from develop where we are doing

Package managers keep using git as a database, it never works out
Using git as a database is a seductive idea. You get version history for free. Pull requests give you a review workflow. It’s distributed by design. GitHub will host it for free. Everyone already knows how to use it. Package managers keep falling for this. And it keeps not working out. Cargo The crates.io index started as a git repository. Every Cargo client cloned it. This worked fine when the re
You can create actions to perform tasks in your repository. If you're making a custom action, it will require a metadata file that uses YAML syntax. Note You can build Docker container, JavaScript, and composite actions. Actions require a metadata file to define the inputs, outputs, and runs configuration for your action. Action metadata files use YAML syntax, and the metadata filename must be eit
"When I see a door with a push sign, I pull first to avoid conflicts" - anonymous For those that work with git for some time, it is not often that you get to discover new things about it. That is if you exclude the plumbing commands which probably most of us don't know by heart and most likely that's for the better. To my surprise, I recently found out about 2 new additions to the list of high-lev

research!rsc: Hash-Based Bisect Debugging in Compilers and Runtimes
Setting the Stage Does this sound familar? You make a change to a library to optimize its performance or clean up technical debt or fix a bug, only to get a bug report: some very large, incomprehensibly opaque test is now failing. Or you add a new compiler optimization with a similar result. Now you have a major debugging job in an unfamiliar code base. What if I told you that a magic wand exists

How I Use Git Worktrees
How I Use Git Worktrees Jul 25, 2024 There are a bunch of posts on the internet about using git worktree command. As far as I can tell, most of them are primarily about using worktrees as a replacement of, or a supplement to git branches. Instead of switching branches, you just change directories. This is also how I originally had used worktrees, but that didn’t stick, and I abandoned them. But re
