I remember one way a program would detect the presence of a debugger was to rely on the fact that cache memory was write-through, not write-back. This would modify the code in memory, but not in cache. When a debugger comes along and you step the code, the cache would get flushed every time so it would load the modified version and execute differently. This technique would fail with the advent of write-back cache support. So later 486’s and pentium onward could not run those games.

The situation won’t be resolved until Russia has truly been broken or Ukraine has nukes. They will not stop until they have what they want at any cost or they perceive Ukraine as a credible threat.

Long range missiles are great, but Ukraine needs to really break them or they will just keep going.
