Why 100 Meters Is Ethernet's Reliability Boundary, Not a Speed Cliff

This article explains why 100 meters is the standard Ethernet channel limit, how signal attenuation and crosstalk degrade reliability beyond that distance, why cable category (Cat5e/Cat6/Cat6A) determines maximum distances for 1Gbps and 10Gbps, and when to use switches or fiber for longer runs.

Why Linux Has /bin and /usr/bin: A 1971 1.5MB Disk Crisis

The split between /bin and /usr/bin originated in 1971 when Ken Thompson and Dennis Ritchie ran out of space on a 1.5MB PDP-11 disk, prompting them to spill overflow commands onto a second disk mounted at /usr—a pragmatic hack later mythologized as intentional design, causing decades of confusion until modern distributions merged them via usrmerge.
