    Third: Cert Spotter now tells you who REALLY issued a certificate, and who you need to contact to get it revoked, which will reduce confusion and save you precious time responding to an unwanted certificate. (6/9)

    Second: say goodbye to alert fatigue! I know you're busy, so I only want to bother you when there's really a problem. If you trust some CAs, you can choose not to be alerted about their certificates. Trusting the 1-3 CAs that you use is WAY better than trusting all 100+. (4/9)

    First: expiration monitoring! Cert Spotter now monitors every one of your domains and sub-domains found in CT logs and alerts you about expiring certificates - whether it's a forgotten manual certificate, or a broken automated certificate. (2/9)

    Monitoring Certificate Transparency logs requires a fair amount of disk space (from )

    One consequence of this is the order in which filenames are returned when listing them using readdir(2) in the standard C library libc: HFS+ has returned filenames in lexicographic order after normalisation, whereas APFS will return filenames in order according to their hashes. I’m sure that will catch someone out.
    When you install macOS High Sierra on the Mac volume of a solid-state drive (SSD) or other all-flash storage device, that volume is automatically converted to APFS. Fusion Drives, traditional hard disk drives (HDDs), and non-Mac volumes aren't converted. You can't opt out of the transition to APFS.

    When you're done, you can learn how to start an electrical fire in "32 Electronic Power Supply Projects", how to shoot your eye out in "All About Airguns", and how to impale yourself on a stalagmite in "Cave Exploring". Just a small sample of the oeuvre of Robert J. Traister.
