Basecamp (37signals)の利益率は相変わらずすごいなあ
Since we started offering employee profit sharing in 2020, we've paid out over $24,000,000 to employees.
We've never offered stock options. Not a fan of future maybe money. We pay real cash to real people so they can spend it on real things right now.
When you choose to be our customer, you're making this possible. You're supporting an independent, fully customer-funded business that shares its success with the people who make it happen.
You don't need investors, stock options, or complicated cap tables to share your success. You can just share the profits. It really can be that simple.
If you're curious, this is how the profit sharing plan works:

Any startup that hires enough ex-Googlers ends up with an ad hoc, informally-specified, bug-ridden, slow implementation of half of Google infra
New on our Engineering blog: Creating in-house source control.
In May, we merged around 2,500 code changes per day. In September, we merged more than 30,000 per day. As a result, we became bottlenecked by developer infrastructure built for human (rather than agent) scale.
Here, we share how we built a new version control system—and fully migrated our monorepo from git—in five months: anthropic.com/engineering/re…
ClaudeのEffortについての調査まとめ、要点はこんな感じ。
- 仕様作成〜実装はLow/Mediumでやる
- 検証やテストの段階でHighにすると探索的にエッジケースなどがカバーされてスコアが向上した
- モデルが間違ったアプローチに進んでいる場合はEffortを上げても解決にはならない

It's pencils down, people. Writing code by hand is no longer an economically viable skill for most programmers at most companies. But the future of making software has never been brighter. Don't you dare black pill this beautiful moment! youtu.be/vDjW_dRyKXY?si=6Fsf…

In his Rails World 2026 keynote @DHH just said that Basecamp is not using Ruby on Rails for the new Hey version. Replaced the Ruby on Rails backend with Rust. I totally agree with his argumentation. But this must be a shock for many developers. Hell just froze over.
DHH曰く、手でコードを書く時代もWebフレームワークを使ってアプリを作る時代も終了したようだ。
DHH is completely crazy : r/rails reddit.com/r/rails/comments/…
