The ongoing story of seconds on the taskbar (microsoft.com)
Over a decade ago, I noted that early beta versions of the taskbar clock showed seconds, and sometimes even blinked the colon like some clocks do, but it was removed because the blinking colon and updating time were ruining Windows 95’s benchmark numbers due to the need to keep all of the code paths related to text rendering in memory, as well as the stack of the thread in the Explorer process that updates the clock.

Show HN: My from-scratch OS kernel that runs DOOM (github.com/UnmappedStack)
TacOS is a UNIX-like kernel which is able to run DOOM, among various other smaller userspace programs. It has things like a VFS, scheduler, TempFS, devices, context switching, virtual memory management, physical page frame allocation, and a port of Doom. It runs both on real hardware (tested on my laptop) and in the Qemu emulator.

Evertop: E-ink IBM XT clone with 100+ hours of battery life (github.com/ericjenott)
Evertop is a portable PC that emulates an IBM XT with an 80186 processor and 1MB RAM. It can run DOS, Minix, and some other old 1980s operating systems. It also runs Windows up to version 3.0. Because it's based on a powerful yet very low power microcontroller, uses an e-ink display, packs two 10,000mAh batteries, and implements extreme power saving measures, it can run for hundreds or even thousands of hours on a single charge.
