April 25, 2022 Four Eras of JavaScript Frameworks April 25, 2022 I started coding primarily in JavaScript back in 2012. I had built a PHP app for a local business from the ground up, a basic CMS and website, and they decided that they wanted to rewrite it and add a bunch of features. The manager of the project wanted me to use .NET, partially because it’s what he knew, but also because he wanted i
The (not so) hidden cost of sharing code between iOS and Android
The (not so) hidden cost of sharing code between iOS and Android Until very recently, Dropbox had a technical strategy on mobile of sharing code between iOS and Android via C++. The idea behind this strategy was simple—write the code once in C++ instead of twice in Java and Objective C. We adopted this C++ strategy back in 2013, when our mobile engineering team was relatively small and needed to s

A few months ago, after reading about Cloudflare doubling its intern class size, I quickly dusted off my CV and applied for an internship. Long story short: now, a couple of months later, I found myself staring into Linux kernel code and adding a pretty cool feature to gVisor, a Linux container runtime. My internship was under the Emerging Technologies and Incubation group on a project involving g

Companies Using RFCs or Design Docs and Examples of These
RFCs - requests for comment - or Design Docs are a common tool that engineering teams use to build software faster, by clarifying assumptions and circulating plans earlier. There are some similarities between writing automated tests for your code, and writing RFCs before you start working on a non-trivial project: Software engineers who write tests for their code - and ask for code reviews on it -

If you're just getting into compiling your Rust code into WebAssembly and want to load it in a web browser, you might be taken aback by the multitude of ways of doing so. This seems to be due to the differing pace of web browsers implementing web platform features over the years.

日本の歌を歌う海外youtuberが好き。
日本の歌を上手に歌う海外youtuberが好き。 youtubeでどう検索したら、日本語の歌が上手な海外youtuberの動画をもっと見つけられるんだろう。 日本の歌って言うのは、メジャーデビューしている日本人の歌手だったり、ボカロ曲であったり、つまり「歌ってみた」。 youtubeで「歌ってみた」を見てたら、日本語とか表現とか、歌がめちゃ上手い海外youtuberさんが結構いるみたいなのよね。 で、得てしてなぜかめっちゃ再生数少ない。別にそんなに歌が上手いわけじゃない単に有名なだけの日本人youtuber（歌い手？）より、明らかに歌唱技術あるでしょみたいな、でもプロの歌手ではない海外勢がいる。そして再生数は少ない。 例えばボカロ曲で”Hence forth”っていう曲があるけど、アジア系のyoutuberであるKYUNEさんが歌う”Hence forth”がすごくいいと思ってる。 あとK
