cogito, ergo sum, usually translated into English as “It compiles, therefore is C++”

C++ compiler so slow, and does some much optimization, sometimes I think it’s Deep Thought computer from Hitchhiker’s Guide to the Galaxy. You put tons of C++ code in it, and after a while it generates assembly

eax, 42
pop rbp

and you have no idea why.

www.quora.com is useless.

Quite often, answers are useless, e.g., no, you cannot do it; you have to be able to read assembly code. But I can read assembly.

How to disable and enable laptop keyboard. You can use xinput to float the input device under X.

  1. Execute the command xinput list to list your input devices.
  2. Locate AT Translated Set 2 keyboard and take note of its id number; this will be used to disable the keyboard. Also, take note of the number at the end, [slave keyboard (#)]; this is the id number of the master, which will be used to re-enable your keyboard.
  3. To disable the keyboard, execute the command xinput float <id#>, where <id#> is your keyboard’s id number. For example, if the id was 10, then the command would be xinput float 10.
  4. To re-enable the keyboard, execute the command xinput reattach <id#> <master#>, where master is that second number we noted down. So if the number was 3, you would do xinput reattach 10 3.

"wince",
"crimp",
"knoll",

128.5714 BPM, 133.3333 BPM, and 138.4615 BPM are convenient BPMs to make frame-perfect 30 FPS music videos. The first one is 14 frames per beat, the second is 13.5, and the last one is 13 frames per beat. 120 BPM is the best but kind of slow.
