A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog
攻殻機動隊英語版でプラクティス①シャドーイングで喉発音を体感！ - 或る物書きの英語喉と小説まみれのジャズな日々
サブカルチャーの不滅の金字塔であることを多くの人が認めるコンテンツ「攻殻機動隊」は、日本よりむしろ海外で非常に高い評価を受けている。多くの英語吹替版が存在し、それが英語の勉強にもなかなか良いのである。YouTubeで観られる動画を使って英語喉を体感・体得にトライしてみようではないか。 http://kaigai-matome.net/archives/35562830.html 〜公安９課面々の吹替英語はシャドーイングの良質教材だ〜 「攻殻機動隊 THE GHOST IN THE SHELL」はメディアミックスになり過ぎて、パラレルな攻殻が乱立している感があるが、原点は史郎正宗の漫画「攻殻機動隊」からすべてが始まったことを忘れてはいけない。 史郎正宗によって１９８９年に書き始められた漫画が、あくまでも原点だ。その上で、世界的に知られるようになったのは押井守監督の劇場版第一作だ。 劇場版「攻

I've found that one of the best ways to understand a new concept is to start from the very beginning. Start from a place where it doesn't exist yet and recreate it yourself, learning in the process not just how it works, but why it was designed the way it was. This isn't a practical guide to async, but hopefully some of the background knowledge it covers will help you think about asynchronous prob

That vision means Workers is about more than just edge compute -- we're rethinking how applications
Can You Believe This Right Now? | By Lars Nootbaar
日本語版はこちら This time three years ago, I was literally working a 9-to-5 job. Actually, it was more like a 5-to-3. Five in the morning to three in the afternoon. This was in 2020, after the minor league season was canceled. I had moved back home from spring training in Jupiter, Florida, to my parents’ place in El Segundo. And at first it was sick. I’d wake up, throw on some sweats, and head over to US
Patterns for Building LLM-based Systems & Products [ llm engineering production 🔥 ] · 66 min read Discussions on HackerNews, Twitter, and LinkedIn “There is a large class of problems that are easy to imagine and build demos for, but extremely hard to make products out of. For example, self-driving: It’s easy to demo a car self-driving around a block, but making it into a product takes a decade.”
Data Structures & Algorithms I Used Working at Tech Companies
Do you actually use data structures and algorithms on your day to day job? I've noticed a growing trend of people assuming algorithms are pointless questions that are asked by tech companies purely as an arbitrary measure. I hear more people complain about how all of this is a purely academic exercise. This notion was definitely popularized after Max Howell, the author of Homebrew, posted his Goog
Typeclass metaprogramming is a powerful technique available to Haskell programmers to automatically generate term-level code from static type information. It has been used to great effect in several popular Haskell libraries (such as the servant ecosystem), and it is the core mechanism used to implement generic programming via GHC generics. Despite this, remarkably little material exists that expl
