  • Sophie’s Cabinet Of Computing Curiosities
    • Ninety-six connector families, scientifically assessed for tangles, snagging, and other crimes committed behind desks.
    • A journey from punched cards and magnetic tape to enormous SSDs—and an explanation of why your “1 TB” disk is really only 0.91 TiB.
    • Splendidly improbable ways of remembering bits, including the 2.88 MB floppy that stubbornly refuses to die.
    • Seventy-one families of interfaces, buses, and networks, from serial ports and thin Ethernet to USB, Thunderbolt, chiplets, and the terabit future.
    • The physics, security implications, and debugging lessons hidden inside the cables and protocols we casually rely upon.
    • File systems from CP/M, 8.3 filenames, and the great / versus \ schism to NTFS, Unix inodes, ZFS, APFS, object stores, and forensic recovery.
    • Standards wars, file formats, codecs, containers, and the improbable business of deciding what data actually mean—with further drawers still being constructed.
    • Technological archaeology asking how things work, why anyone thought they were a good idea, what went wrong, and why supposedly obsolete ideas simply will not die.
    • “Geek Media: Get Out Less!”
  • Caine in One Frame
    • Testing a theory about Michael Caine films.
    • 32 out of the approx 130 films he has appeared in.
