A while ago, I got reminded of a few occurrences of Delphi apps hanging after a little less than 2 months of being active.
It does not happen that often, as usually Patch Tuesday requires a reboot, but sometimes it doesn’t, or ops forgot to patch the affected machine.
The common thing for these hanging apps was that they all used the System.Threading unit (introduced in Delphi XE7). That unit relied on [Wayback] TThread.GetTickcount (added in Delphi XE3 in the System.Classes unit) which uses a 32-bit unsigned [Archive.is] cardinal value as it relied on the Windows API [Wayback] GetTickCount function which in turn has this remark:

Before digging into Wake-on-LAN on Windows machines, I’ll interlude with basically the canonical wakonlan available on many non Windows machines
On Linux and BSD machines, there is the Perl script wakeonlan (steadily at version 0.41) at [Wayback/Archive.is] jpoliv/wakeonlan: Perl script for waking up computers via Wake-On-LAN magic packets (script: [Wayback/Archive.is] wakeonlan/wakeonlan at master · jpoliv/wakeonlan) with this help:

Since I will be bitten by this someday, here the september 2021 observation that [Wayback] By default, scp(1) now uses SFTP protocol.
The original scp/rcp protocol remains available via the -O flag.
