IntroductionToday, June 21, 2022, Cloudflare suffered an outage that affected traffic in 19 of our data centers. Unfortunately, these 19 locations handle a significant proportion of our global traffic. This outage was caused by a change that was part of a long-running project to increase resilience in our busiest locations. A change to the network configuration in those locations caused an outage

When you open a document with an encoding different than the one it was created with, it's not possible to display the original text, and instead a garbled mess of corrupted characters are printed out.

TL;DR: Instead of redirecting API calls from HTTP to HTTPS, make the failure visible. Either disable the HTTP interface altogether, or return a clear HTTP error response and revoke API keys sent over the unencrypted connection. Unfortunately, many well-known API providers don't currently do so. Updates 2024-05-24: Added the Google Bug Hunter Team response to the report that the VirusTotal API resp
At over thirty years old, HTTP is still the foundation of the web and one of the Internet’s most popular protocols—not just for browsing, watching videos and listening to music, but also for apps, machine-to-machine communication, and even as a basis for building other protocols, forming what some refer to as a “second waist” in the classic Internet hourglass diagram. What makes HTTP so successful

「コオロギ食」への嫌悪感は「ネオフォビア（新奇性恐怖）」なのか（石田雅彦） - エキスパート - Yahoo!ニュース
政府のデジタル大臣が試食し、それがネット上で問題視されるなど、最近になって物議をかもしているコオロギ食だが、コオロギを食べることに心理的な抵抗がある人が多いことも背景にありそうだ。新奇なものに恐怖を感じることをネオフォビア（Neophobia、新奇性恐怖）というが、日本人にとってのコオロギ食はネオフォビアなのだろうか。 まだ国際的な規範もない昆虫食 主にアジア、アフリカ、南アメリカといった地域で人類は長く昆虫を食べてきた。この昆虫食や昆虫の飼料化が世界的に注目を集めているのは、2013年に国連の食糧農業機関（Food and Agriculture Organization of the United Nations、FAO）が食糧危機の解決策として昆虫食を推奨したことに始まる。 その後、日本をはじめ各国は、食糧危機解決策の一つとして昆虫食の推進を始めるようになっていった。また、SDGs（
State of JS 2020
As crappy as 2020 was, JavaScript as a whole still managed to somehow move forward. As the language itself keeps improving thanks to new features like Optional Chaining and Nullish Coalescing, TypeScript's widespread adoption is taking things to a whole other level by popularizing static typing. And on the framework side, just when we thought things were settling down, Svelte comes in and shakes e
