日米OSDN離合集散、苦闘の21年史
さて、ついに退職エントリだ。私は米国のオープンソース・ムーブメントを日本で再現するためのコアを作るために民間企業へやってきたはずだった。それから21年、随分と長い航海になってしまったが、結局様々な尻拭いを続けてきたという感慨ばかりが起きてくる。一つの歴史として書き残すいいタイミングなのでその苦闘を振り返っておこう。 なお、長く付き合いが続いてしまう米国側法人は下記のように名称が変化している。なるべく頭に米国と付けて日本側法人と区別しやすいように記述するが、突然名称が変わったりするので注意してほしい。多くがもはや消滅した法人のことなので、さすがに一気読みするような酔狂な人はほぼいないと思うが。 VA Research Andover.net ↓ ↙︎ (VAによる買収) VA Linux Systems ↓ ↘︎ (Andoverから社名変更) VA

Last week, I built a tiny Linux system from scratch, and booted it on my laptop! Here’s what it looked like: Let me tell you how I got there.

In the end, I had a tiny Linux system with a size of 2.5 MB,

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,
第673回の「カーネルのクラッシュ情報を取得する」では、カーネルクラッシュ時に情報を収集する仕組みを有効化しました。得られた情報は活用しないと意味がありません。今回はその中身を解析する方法を紹介します。 デバッグパッケージのインストール 第673回では、意図的にシステムをクラッシュさせることで、dmesgとvmcoreを取得しました。カーネルが今際の際に次につながる情報を残してくれたのです。「しかしながらあのクラッシュが最後のpanicだとは思えない。もし、同じカーネルが続けて使われるとしたら、あのpanicの同類が、また世界のどこかへ現れてくるかもしれない……」 最初に行うべきなのは、前回紹介したように問題発生時のdmesgを読むことです。これである程度、状況の絞り込みは行えますし、運が良ければ原因がわかることもあります。しかしながら、dmesgだけだと「問題が起きた場所」はわかっても

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

Why GitHub Actually Won
A few days ago, a video produced by @t3dotgg was posted to his very popular YouTube channel where he reviews an article written by the Graphite team titled “How GitHub replaced SourceForge as the dominant code hosting platform”.

What Comes After Git
Git was born from the collaboration problems in the Linux kernel. Nearly a decade later, new problems arose when Kubernetes (the operating system of the cloud) brought open-source collaboration to a new level. I saw the pain points of git (and GitHub) firsthand working on Kubernetes open-source. Will a new version control system (or something that solves similar problems) spring up? Some ideas on

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
OpenBSD is an operating system that's famous for its focus on security. Unfortunately, OpenBSD leader Theo states that there are only 7000 users of OpenBSD. So it's a very small but elite group, that wields a disproportionate influence; since we hear all the time about the awesome security features these guys get to use, even though we usually can't use them ourselves.
