Downloading torrent files
Using 'binwalk -E' or 'binwalk -E -F', you can easily see which blocks of a torrent file are already downloaded, and which are zero/empty blocks...
As of high-entropy music and video files, you can quickly see if it was downloaded fully, without zero blocks remained.
A real example: binwalk output and what qBittorrent shows.
I really do this when I find some (maybe (un)-finished) video file in Downloads directory.
Also, an archiver (like 7z, RAR, ZIP) can skip high-entropy files (because they are already uncompressable) to increase archiving speed. (Entropy can be measured quickly by small random spots in file.)
A more sophisticated compressor (like gzip, bzip, xz) can detect high-entropy spots in a file and skip them.

Some time ago (before 24-Mar-2025) there was Disqus JS script for comments. I dropped it --- it was so motley, distracting, animated, with too much ads. I never liked it. Also, comments didn"t appeared correctly (Disqus was buggy). Also, my blog is too chamberlike --- not many people write comments here. So I decided to switch to the model I once had at least in 2020 --- send me your comments by email (don"t forget to include URL to this blog post) and I"ll copy&paste it here manually.
Let"s party like it"s ~1993-1996, in this ultimate, radical and uncompromisingly primitive pre-web1.0-style blog and website.
