Bring back to life Hyprland with ML4W 2.9.7 Dotfiles as second DE for Manjaro-KDE-24.1.2-241104 KVM Guest
Straight forward run `sudo pacman -Syyu` on Manjaro KDE as of 11/04/2024 failed. Several commands shown bellow finally brought me to success. Having stable Manjaro release rolled forward to a final state we can just replace "downgrade" by "manjaro-downgrade" to reproduce same approach as in my previous post to Lxer.com . Current version of ML4W Dotfiles appears to be 2.9.7.1DEV.

University of Toronto ☛ The modern world of server serial ports, BMCs, and IPMI Serial over LAN
Once upon a time, life was relatively simple in the x86 world. Most x86 compatible PCs theoretically had one or two UARTs, which were called COM1 and COM2 by MS-DOS and Windows, ttyS0 and ttyS1 by Linux, 'ttyu0' and 'ttyu1' by FreeBSD, and so on, based on standard x86 IO port addresses for them. Servers had a physical serial port on the back and wired the connector to COM1 (some servers might have two connectors). Then life became more complicated when servers implemented BMCs (Baseboard management controllers) and the IPMI specification added Serial over LAN, to let you talk to your server through what the server believed was a serial port but was actually a connection through the BMC, coming over your management network.

James G ☛ Thinking about personal website style galleries
My first thought is to think about this in terms of a “website style gallery” – a place where I can curate and collect styles for my website. I don’t like the idea of a “style guide,” the connotations being more about restriction than creativity. Rather, I wanted to build a place of reference: somewhere I can go to see all the main styles of my website.

Markup from Hell ☛ Control the Viewport Resize Behavior on mobile with `interactive-widget` - HTMHell
Viewports units on mobile have been a problem for a long time. Using 100vh is most likely not exactly what you initially expected it to be. To fix this, the CSS Working Group came up with more units over time for you to use. The dynamic viewport units got introduced, which include svh and lvh which represent 1% of the small and large viewport height respectively.
