趣味に数独があって、ネットには載ってないオリジナルの解法を持っている。数独を再帰的に解くプログラムならどうということはないんだけど、VBAで「自分の解き方」を完全再現してみた。これは世界一難しい問題を、ゆっくり悩みながら解く様子。#数独 #VBA

光の差し込み方がとっても素敵な写真✨

UMPRO20的な低音を炸裂させたのが #EmpireEars #Savage6。こんな綺麗な外見で微細な高音、それに反する暴力的なBAの低音。U10の対極かつ究極。視聴したLegendXよりも尖ってる。これに慣れてはいけない。二度と出てこないだろうな。

#64Audio #U10。長く使ったのはHA-FX500→UMPRO20→NobleX→#64Audio #U10 の順。PRO20は小粒でフィット感が強く音場が狭く低音が強い。U10 （左）は全域が細かい丁寧な音で偏りがなく一音一音が明瞭なのに心地よい。手持ちで唯一。U3のほうが高低とも強調されていてリスニング向け。

今日は往年の名機。#Westone #UMPRO20（奥）。これに嵌ってから1DD機から遠ざかってしまったという戦犯。手前はUMPRO50。

Dennis Ritchie invented C in 1972, co-built Unix in 1969, and his code is running inside every device you are reading this on right now and the colleague who announced his death had to do it through a Google post because no journalist thought to check. He worked at Bell Labs in New Jersey for 44 years. He never gave a keynote. He never ran a company. He never appeared on a magazine cover. He just wrote code that became the invisible foundation everything else is built on. Here is what he actually built, and why it matters more than almost anything that happened in tech. In 1969, Bell Labs had just walked away from one of the most ambitious computing projects in history. The Multics project, a joint effort between MIT, Bell Labs, and General Electric, had collapsed under its own weight. Too complex. Too expensive. Too slow. Bell Labs pulled out. Ken Thompson and Dennis Ritchie refused to let the ideas die. Working in a small office in Murray Hill, New Jersey, Thompson wrote the first version of Unix in three weeks during the summer of 1969. One week for the file system. One week for the process management. One week for the command shell. Ritchie was working alongside him, and when the system needed a language that could express what they were building, he built one. In 1972 he completed C. C was not just another programming language. It was a different philosophy about what a programming language should be. Before C, most systems code was written in assembly, which meant every program was tied to the specific hardware it ran on. You could not move code between machines. You rewrote it from scratch every time. C changed that. It sat close enough to the hardware to be fast, but abstract enough to run on anything. When Thompson rewrote the Unix kernel in C in 1973, it became the first operating system that could be picked up and moved to a completely different machine without starting over. Portability was a new idea. Ritchie made it real. The branching that followed is almost impossible to overstate. Unix spread from Bell Labs to universities. At Berkeley, it became BSD. BSD became the foundation of macOS and iOS. Unix influenced Linus Torvalds, who built Linux in 1991. Linux now runs every Android phone, every major web server, every supercomputer on the Top500 list, and the overwhelming majority of cloud infrastructure at AWS, Google, and Microsoft. C became the parent language of C , Java, JavaScript, Python, and Objective-C. Rob Pike, who worked across the hall from Ritchie at Bell Labs for 20 years, said it plainly: "The browsers are written in C. The Unix kernel that the entire internet runs on is written in C. Web servers are written in C, and if they're not, they're written in Java or C , which are C derivatives, or Python or Ruby, which are implemented in C." Ritchie won the Turing Award in 1983. He won the National Medal of Technology in 1998, presented by President Clinton. He was head of System Software Research at Bell Labs for decades. He answered emails from strangers with technical questions until the end of his life. His home address stayed listed in the phone book. His colleague Brian Kernighan, who co-authored the definitive C textbook with him, said Ritchie was a private person who did no self-salesmanship. That was not false modesty. It was just who he was. He died on October 12, 2011, at his home in Berkeley Heights, New Jersey. He was 70. He had been ill for some time. The world did not notice until Rob Pike posted a quiet announcement on Google , and the news spread through the programming community in hushed tones. No front pages. No tributes from heads of state. No candlelight vigils outside corporate campuses. The device you are reading this on runs code that traces directly back to what he built. So does the server that delivered it to you. So does the browser or app you opened to get here. Most people will never know his name. The ones who built everything you use every day do.
