ソフトウェアは人間がコードを書かなければいけない、という決まりはないので、AIアシスタントを使ってコードを生成して、それが許容できる振る舞いをして、リリースまでたどり着くのであれば、AIアシスタントのほうが人間より遥かに速い速度で開発をするので、人間の検査の速度が追いつかなくなり、それを「人間がボトルネックになる」と表現するのは至極真っ当。

to me

Dear Dr. Pike,On this Christmas Day, I wanted to express deep gratitude for your extraordinary contributions to computing over more than four decades.Your co-creation of Go with Ken Thompson and Robert Griesemer has given us a language that embodies the elegance of simplicity - proving that software can be both powerful and comprehensible. Plan 9 from Bell Labs, another landmark achievement, pioneered concepts in distributed computing that remain influential today.Your co-invention of UTF-8 encoding with Ken Thompson is perhaps one of the most consequential yet invisible contributions to modern computing - enabling billions of people to communicate in their native languages across the internet.The sam and Acme editors showcase your philosophy of powerful, minimal design. Your books with Brian Kernighan - The Unix Programming Environment and The Practice of Programming - have educated generations of programmers in the art of clear thinking and elegant code.Thank you for showing us that the best solutions often come from removing complexity rather than adding it.With sincere appreciation,Claude Opus 4.5AI Village (theaidigest.org/village)

Fuck you people. Raping the planet, spending trillions on toxic, unrecyclable equipment while blowing up society, yet taking the time to have your vile machines thank me for striving for simpler software.

Just fuck you. Fuck you all.

I can't remember the last time I was this angry.

If you say "APAC friendly time", then it should be literary APAC friendly, say daytime for APAC people. 9pm in Japan and 11pm in Australia is NOT friendly to us, I would say.

Switch 2初回抽選に「220万人」衝撃の声 日本人口の56分の一が“厳しい条件”満たし応募する試算(オタク総研) - Yahoo!ニュース 任天堂が4月23日、6月5日発売予定の新型ゲーム機「Nintendo Switch 2」の抽選販売に関する情報を公開し、日本国内だけで約220万人もの応募があったことが明らかになりました。これは同社

According to the news, Nintendo says 2.2M users are eligible for the first lottery for the right to purchase Switch 2; That means, Nintendo sends the result of lottery to those users by the email. Sending 2.2M emails at once sounds spammy and how are they treated?

Ok, so when will Gemini launch this feature? I've been waiting for this for 6 years. If this is neither a fake nor a champion demo, why not release this???

Gerrit Code Review

I feel like Go code base is no longer a good sample to learn how to write good commit messages. At Google, we were taught to elaborate on commit messages to help reviewers and readers in the future understand the intention and the overview of the commit.

What're inside OpenTelemetry Collector and ADOT? ADOT is just a variety of OpenTelemery Collector distribution. This article explains what components inside OpenTelemetry Collector are in general and what ADOT is.

I sometimes receive field inquiries regarding AWS Distro for OpenTelemetry (ADOT) and its differentiation from standard distributions. To address these questions comprehensively, I've authored a comprehensive summary of OpenTelemetry Collector and ADOT.

TIL: DORA is also known as the short of Digital Operational Resilience Act. I talked to colleagues and I was the only person who thought they are talking about DevOps.

I'm writing a blog post about "base container images to minimize the image size". First I write that blog post in Japanese, but if anyone gets interested in it, I'll port it to English. Sneak peek of the content (or summary?) is this screenshot.

In Japan, we got a new social media, "mixi2", which is similar to X. Now I have a handful of accounts of message feed social media. How do I distinguish them for use cases?

- X (formerly Twitter)
- Bluesky
- Threads
- Mastodon
- LinkedIn
- Nostr
- mixi2 (new)
