Understanding Garbage Collection in JavaScriptCore From Scratch
JavaScript relies on garbage collection (GC) to reclaim memory. In this post, we will dig into JSC’s garbage collection system. Before we start, let me briefly introduce myself. I am Haoran Xu, a PhD student at Stanford University. While I have not yet contributed a lot to JSC, I found JSC a treasure of elegant compiler designs and efficient implementations, and my research is exploring ways to tr
`zig cc`: a Powerful Drop-In Replacement for GCC/Clang - Andrew Kelley
`zig cc`: a Powerful Drop-In Replacement for GCC/Clang If you have heard of Zig before, you may know it as a promising new programming language which is ambitiously trying to overthrow C as the de-facto systems language. But did you know that it also can straight up compile C code? This has been possible for a while, and you can see some examples of this on the home page. What's new is that the zi

裸の画像の乳房・陰毛等から年齢を立証するという「タナー法」というのは、医学文献には存在せず、一部の内科医の供述や警察の内部資料にのみ存在すること - 児童ポルノ・児童買春・児童福祉法・監護者性交・不同意性交・不同意わいせつ・青少年条例・不正アクセス禁止法・わいせつ電磁的記録・性的姿態撮影罪弁護人 奥村徹弁護士の見解（弁護士直通050-5861-8888 sodanokumurabengoshi@gmail.com）
最近の「タナー法」の評価について書いておきます。 「タナー判定」というのは、小児科医の分野で人の性的成熟度を測る指標である。 小児科学 第3版（医学書院)p17 思春期の性成熟と成長 思春期は，小児から成人への移行の過渡期にあたる時期で，種々の成熟段階を経て身体全体が成人に成熟する。この過程は多くの神経内分泌因子やホルモンによって制御されているが，最終的には，下垂体から分泌されるゴナドトロピン(性腺刺激ホルモン)と性腺から分泌される性ステロイドホルモンが上昇して，二次性徴を発現・成熟させる。 何が思春期開始の引き金になるかは，完全には明らかではないが，栄養や脂肪細胞から分泌されるレプチンなどが関与していると考えられている。 (1)二次性徴の成熟 思春期の発来は，男子においては精巣容量の増大から始まり，陰茎増大，陰毛発生と進んでいく。女子においては乳房の発育から始まり，陰毛発生，初経と進んで

Deno is a Browser for Code
I started contributing to Deno soon after Ry made the prototype visible in May 2018. The most frequent question that people have is "where is the package manager?" which often times isn't even in the form of a question. It is statements like "I thought Deno took security seriously, and just downloading resources off the internet is insecure." or "How can I possibly manage my dependencies?" In my o

HTML の適切な数字入力について調べてみた (type, inputmode, pattern) - Goodpatch Tech Blog
適切な数字入力とは? 2022/7/25 更新 ・ 論点を明確にするために、この記事で扱う郵便番号の仕様を、7桁の数字 => 3桁 + 4桁の数字 に変更しました。 Design Div 所属フロントエンドエンジニアの上垣です。 Webサービスを作成するにあたり、フォーム周りのユーザー体験は特に慎重に設計する必要があると考えています。なぜなら、フォームはユーザーとサービスをインタラクティブにつなぐ重要な接点であり、フォームの体験はサービス全体に対する印象に直結するからです。 そんな中で、郵便番号の入力フォームを作成する際、ふと「郵便番号の入力に適切な type は何だっけ?」と思い立ったので、調査してみました。 ※この記事で想定している郵便番号の仕様 = 3桁 + 4桁の数字 (郵便番号を2つの input に分割するのは適切かという問題は、この記事では扱いません。) type="numb
