      I'm trying to understand this topic more, so I'm curious what you mean by the word tracking. I searched around, and wanted to check if my understanding is roughly correct:

      Is tracking when the frequency data of the instrument, and the frequency+tempo changes in the music track are stored? And does midi just say "guitar" or "piano" and leave it up to the software to decide what those instruments sound like? So tracking would always reproduce the same sound, while midi can vary, even if it's making the same tones?

      For e.g. an acoustic guitar and an electric guitar might both be producing a note at a particular base frequency (e.g. C2) but the overtones and amplitudes of those overtones would be completely different, giving each instrument their particular sound. So does tracking record that overtone distribution for each instrument, to ensure an acoustic guitar sounds like an acoustic guitar (that the music composer wanted)?

      This is the source that I was reading - https://scalibq.wordpress.com/2017/03/29/trackers-vs-midi/

      If not, I'd really appreciate any other reading material to understand what you mean by tracking, thanks!

      Have you ever heard of "Windows Defender"? They got more than 96.2% of detection rate according to AV Comparatives in September 2016[1].

      Have you ever heard of "Windows 10"? They got less CVE vulnerabilities reported in 2016 than Android, Debian, Ubuntu, Flash Player, Adobe Reader, Mac OS X, The Linux Kernel, iOS, even Chrome and Firefox[2].

      If these are not examples of "adequate or even reasonable protection", then you got really unrealistic expectations or you're simply hating Microsoft for the sake of hating them.

      As I said, it is not possible to deliver bug-free code, and you learn to live with it or you die hating every software vendor in the world.

      Just remember, falling in the "I don't need AV, I don't use Windows" fallacy will bite you, and will bite you hard[3].

      > PS3 never used OpenGL

      It sort of does. PS3 uses OpenGL ES 1.0 with extensions and then there is a separate graphics library, LibGCM, that is lower level.

      Details here (although this use says it doesn't use OpenGL and then says that its API is based on OpenGL + extensions, so it is a bit confusing):

      EDIT: HEre is a PS3 developer saying that PS3 is OpenGL ES:

      And the expiration of a few patents, like the ones about simultaneous multithreading. Zen is the first AMD's architecture to implement SMT, Bulldozer had CMT (https://www.extremetech.com/wp-content/uploads/2015/04/zen.jpg).

      Yes, I posted a followup which investigates the issue somewhat further.
      It appears to be some bug with the message queue handling, specifically when the UI is in Aero mode. In classic mode, the problem is not there. In Windows XP, the problem is also not there.
