Note 本記事の内容は Linus 氏の発言が人を傷つける場合に筆者がそれを良しと考えるといった意図はございません 少し古い記事になるが、 Linus Torvalds 氏 の GitHub に対する苦言が記事になっていた。 LinuxカーネルにNTFSドライバーが追加、トーバルズ氏はGitHub経由のマージに苦言 - ZDNet Japan Linus 氏が GitHub について苦言を呈するのは今に始まったことではない（後述）が、 別に GitHub のすべてを否定しているわけではない。[1] では一体何が不満なのか。Linus 氏の理想とする git の開発フローを考察した上で、整理してみたい。 Linus 氏の理想 結論からいうと、 「意味あるコミットを作れ」「コミットを大事にしろ」 という思想が伺える。 では 「意味あるコミット」「大事にされたコミット」 とは何なのか。 筆者な

Netlinkを学び始めました。記録です。 今回はNetlink メッセージをコードで書く内容であったり、そのメッセージをキャプチャしてバイナリを読みながらNetlinkを理解する記事になります。 Netlinkとは? ユーザー空間とカーネル空間のやりとりを行う事が出来るLinux kernelのサブシステムです。 Netlinkは、socket通信を利用してユーザー側はカーネル空間との通信を行う事が出来るため通常のネットワークプログラミングと同じように、Netlinkに関する様々な要素を持ったヘッダーを付加し送信を行った後、recv関数といったソケットからメッセージを受け取る関数を使用する事でカーネル空間とユーザ空間の通信を実現しています。 linuxjm.osdn.jp ネットワーク経由でNetlinkを使用する主な要素としては以下が挙げられます。 経路テーブルに関する操作(例:追加,

Two years ago more or less I started my journey in Linux. I was scared at first and I didn’t know where to start from. But then I decided to buy a book - and what a book! - in order to follow a path. Along the way, I integrated the material with up-to-date documentation from kernel.org and source code. In the meantime, I started to learn C a bit so that I also could have played with what I was lea
Exactly twenty years ago, on April 7, 2005, Linus Torvalds made the very first commit to a new version control system called Git. Torvalds famously wrote Git in just 10 days after Linux kernel developers lost access to their proprietary tool, BitKeeper, due to licensing disagreements. In fact, in that first commit, he’d written enough of Git to use Git to make the commit! Git’s unconventional and

A Git story: Not so fun this time | Brachiosoft Blog
Linus Torvalds once wrote in a book that he created Linux just for fun, but it ended up sparking a revolution. Git, his second major creation, was also an accidental revolution. It’s now a standard tool for software engineers, but its origin story wasn’t so much fun this time, at least for Linus. Linus doesn’t scale 1998 was a big year for Linux. Major companies like Sun, IBM, and Oracle started g

They demonstrate up to a 100x reduction in tail latency. These are my notes on the paper. This is the foundational

Jun 19, 2024 Why I am not yet ready to switch to Zig from Rust I am not going to lie: I love programming in C. I know it’s a little bit irrational, but programming in C just feels right. Perhaps that’s because I did spend a lot of time programming with C as I contributed to the Linux kernel. Those were good times because I had the opportunity to learn from some of the best C programmers in the wor

The Rust programming language feels like a first generation product. You know what I mean. Like the first iPhone - which was amazing by the way. They made an entire operating system around multitouch. A smart phone with no keyboard. And a working web browser. Within a few months, we all realised what the iPhone really wanted to be. Only, the first generation iphone wasn't quite there. It didn't ha
