21 May The balance has shifted away from SPAs Posted May 21, 2022 by Nolan Lawson in Web. Tagged: spas. 24 Comments There’s a feeling in the air. A zeitgeist. SPAs are no longer the cool kids they once were 10 years ago. Hip new frameworks like Astro, Qwik, and Elder.js are touting their MPA capabilities with “0kB JavaScript by default.” Blog posts are making the rounds listing all the challenges
GitHub - zevv/zForth: zForth: tiny, embeddable, flexible, compact Forth scripting language for embedded systems
From Wikipedia: A Forth environment combines the compiler with an interactive shell, where the user defines and runs subroutines called words. Words can be tested, redefined, and debugged as the source is entered without recompiling or restarting the whole program. All syntactic elements, including variables and basic operators are defined as words. Forth environments vary in how the resulting pro
Why not use GraphQL?
Are you looking for an Open Source Graph Manager? Cosmo is the most complete solution including Schema Registry, Router, Studio, Metrics, Analytics, Distributed Tracing, Breaking Change detection and more. I think GraphQL will change the world. There will be a future where you can query any system in the world using GraphQL. I'm building this future. So why would I argue against using GraphQL? My

Ice Cream Cone Car
Claim: A flavor of ice cream being transported affects a car's performance: every time vanilla is the driver's choice, the car stalls. This is a weird but true story ... A complaint was received by the Pontiac Division of General Motors: This is the second time I have written you, and I don't blame you for not answering me, because I kind of sounded crazy, but it is a fact that we have a traditi
Artificial Intelligence (AI) is transforming the way we build, debug, and optimize code, and it’s happening at an unprecedented pace. As a long-time Ruby and Rails developer, I’m participating in these developments with excitement via my startup and my new book and open-source projects. The good news I want to share is: not only will Ruby and Rails survive this AI revolution, Rubyists will pioneer
On the ‹dl›
Introduction The <dl>, or description list, element is underrated. It's used to represent a list of name–value pairs. This is a common UI pattern that, at the same time, is incredibly versatile. For instance, you've probably seen these layouts out in the wild… Each of these examples shows a list (or lists!) of name–value pairs. You might have also seen lists of name–value pairs to describe lodging
繰り返される「教育勅語にはいいことが書いてある」という擁護論のデマ : 脱「愛国カルト」のススメ
＜ざっくり言うと＞ ネットで出回っている教育勅語の「12の徳目」を以って「教育勅語は正しい」と主張するやつは、絶対に本当の教育勅語を読んだことがない。「12の徳目」は教育勅語の全体の1/3にすぎない上に、現代語訳も原文からかけ離れた嘘っぱちである。残り2/3の部分に、神話的国家観や主権在君の考えが書かれており、問題視されているのは主にこの部分である。元の教育勅語には「緊急事態の際には、皇室国家の為にその身を捧げ」て「永久に続く皇室の繁栄をお助けしろ」という内容が書かれている。これが皇室国家の為にその身を捧げる神風特攻などに繋がっていったことは疑うべくもない。実際の教育勅語を読むこともなく、ネットで出回ってる画像を脳みそ停止して鵜呑みにして称賛しているバカを絶対に信頼してはいけない。 ↑断言するが、ツイッター上で「教育勅語の12の徳目」なる画像を貼り付けて教育勅語を称賛している人間は、絶対に
Kafka Without ZooKeeper: A Sneak Peek At the Simplest Kafka Yet
At the heart of Apache Kafka® sits the log—a simple data structure that uses sequential operations that work symbiotically with the underlying hardware. Efficient disk buffering and CPU cache usage, prefetch, zero-copy data transfers, and many other benefits arise from the log-centric design, leading to the high efficiency and throughput that it is known for. For those new to Kafka, the topic—and

Lisp programmers claim that their system of s-expression code in addition to its featureful macro system makes it a metaprogrammable and generalized system. This is of course true, but there's something very broken with lisp: metaprogramming and programming aren't the same thing, meaning there will always be rigid syntax within lisp (its parentheses or the fact that it needs to have characters tha

Product-minded engineers are developers with lots of interest in the product itself. They want to understand why decisions are made, how people use the product, and love to be involved in making product decisions. They're someone who would likely make a good product manager if they ever decide to give up the joy of engineering. I've worked with many great product-minded engineers and consider myse

マックス・マシューズに敬意を表して命名したライブエレクトロニクスを実現するためのコンピュータ環境について、私は長年取り組んできた。現在サポートされている3つのコンピュータプログラムであるMax/MSPとJmax、Pdは、ここで「Max」として参照してゆく共通のパラダイムを拡張した実装と見なせる。Maxパラダイムは今では十分に安定しているように思われ、出版された説明がすぐに古びる恐れは最早あるまい。Max（のパラダイム）が何をうまくでき、何をうまくできず、またこの知識から私たち皆が何を学べるのかを、いまこそ私たちは有益に評価できる。エリック・ライオンが主催する音楽ソフトウェアの未来に関するダートマス・シンポジウムは、このプロジェクトを開始する絶好の機会である。明らかな理由で全く客観的または公平ではないと思われる部分がこの論説にあれば、あらかじめ謝罪しよう。様々な形や舞台でMaxに、あるいはM

Let's learn more about design specs, how to create them, and how they smooth out the hand-off process between design and engineering. What are design specs?

The importance of a handbook-first approach to communication
A handbook-first approach to communication is sneakily vital to a well-run business. While it feels skippable — inefficient, even — the outsized benefits of intentionally writing down and organizing process, culture, and solutions are staggering. Conversely, avoiding structured documentation is the best way to instill a low-level sense of chaos and confusion that hampers growth across the board. G

What is wrong with you, Python?!Python is by far the most used language in machine learning, and Google has a ton of machine learning libraries and tools written in it. So, why Swift? What's wrong with Python? To put it bluntly, Python is slow. Also, Python is not great for parallelism. To get around these facts, most machine learning projects run their compute-intensive algorithms via libraries w
Move over JavaScript: Back-end languages are coming to the front-end
In the early days of networked computing, mainframes did all the heavy lifting: users connected to massive machines with video terminals that could do little more than send and receive text. Then in the 1970s, personal computers came along and made it possible to do serious computing on the client-side as servers handled tasks like authentication and storage in many networks. The rise of the inter
