Latin1 vs UTF8

Latin1 was the early default character set for encoding documents delivered via HTTP for MIME types beginning with /text . Today, only around only 1.1% of websites on the internet use the encoding, along with some older applications. However, it is still the most popular single-byte character encoding scheme in use today. A funny thing about Latin1 encoding is that it maps every byte from 0 to 255 to a valid character. This means that literally any sequence of bytes can be interpreted as a valid string. The main drawback is that it only supports characters from Western European languages. The same is not true for UTF8. Unlike Latin1, UTF8 supports a vastly broader range of characters from different languages and scripts. But as a consequence, not every byte sequence is valid. This fact is due to UTF8's added complexity, using multi-byte sequences for characters beyond the general ASCII range. This is also why you can't just throw any sequence of bytes at it and ex...

Cannabis vs Cognition

Searching through papers this morning curious about evidence-based studies on cannabis (and synthetic cannabis[1][2]) in relation to psychosis, schizophrenia, and general effects on cognition.

I thought this paper was interesting: "An Evidence Based Review of Acute and Long-Term Effects of Cannabis Use on Executive Cognitive Functions"

In some studies, cannabis seemed to increase some users ability to focus. But further studies discovered that while some users experienced improved focus, they often had trouble recalling what they were focused on. The above study is an interesting overview which makes empirical arguments that cannabis largely reduces working memory, impairs executive function, and undermines mental flexibility, and thus might promote users to behave irrationally and impulsively.

yt-dlp Archiving, Improved

One annoying thing about YouTube is that, by default, some videos are now served in .webm format or use VP9 encoding. However, I prefer storing media in more widely supported codecs and formats, like .mp4, which has broader support and runs on more devices than .webm files. And sometimes I prefer AVC1 MP4 encoding because it just works out of the box on OSX with QuickTime, as QuickTime doesn't natively support VP9/VPO9. AVC1-encoded MP4s are still the most portable video format. AVC1 ... is by far the most commonly used format for the recording, compression, and distribution of video content, used by 91% of video industry developers as of September 2019. [ 1 ] yt-dlp , the command-line audio/video downloader for YouTube videos, is a great project. But between YouTube supporting various codecs and compatibility issues with various video players, this can make getting what you want out of yt-dlp a bit more challenging: $ yt-dlp -f "bestvideo[ext=mp4]+bestaudio[ext=m4a]/best...
