The "Hardware" link indicates that the BoM specifies a "24-pin SPI e-paper for GoodDisplay panels (3.97″, 4.26″, 7.5″ and up)." A search turns up this: https://www.good-display.com/product/516.html
First I saw that it's written in Perl. Then I realized that the last release was 11 years ago and that the repository domains are hardcoded in the one-file script.
A gross mischaracterization of the author's point (the word "type" doesn't even appear in the article). The author focuses on the cost of interpreted languages, which he describes as "memory hungry" and computationally expensive.
There are many young, economically disenfranchised Americans that see the military as a way out of poverty. The military understands this and positions recruitment centers in poorer neighborhoods.
I'm in the same position and understand your complaints about the lack of uniformity across applications in Linux DEs. But I use the Linux desktop as a daily driver because I absolutely despise the lack of customization in macOS, especially as it relates to "virtual workspaces" or "virtual desktops." In Linux, I can have multiple different desktops, each named intuitively, and each with its own set of applications. In macOS, I can't even _name_ the virtual desktops. What's more absurd is the "logic" around when an application has focus when it's minimized, and how its window behaves when you Cmd-Tab to it. Utterly exasperating that Apple, a company who has long prided itself on HCI, falls so far short of the mark in intuitive interface behavior.
Widely used? By whom? Devs who don't understand rsync or scp? Give me a practical scenario where a box is running FTP but not SSH.
