Velly interwesting. Line 23 is the critical bit, like a compound literal (struct s){.element1 = 1} but for a scalar, and lets you take address of it without having to create another var. This is for a generic type behaviour.

Playing around with type polymorphism in C. I wanted one function which takes a type enum and a variable of that type without having to declare many functions all working with different types.

Setting the treble on my NAD 302 amp near maximum brings the curve back near the ideal. So it's not just compensating for over 50 hearing loss, and would sound excessively bright for younger people. The measurement shows this is the right setting for this room & positioning.

When I compared the sound with my Ear Fun Air Pro 4 before and after the Audio Science Review curve, I was convinced that you shouldn't worry about what your eq controls _look like_ - what matters is how close you can get to the ideal curve overall.

Jaffa cakes, whilst being partly coated biscuits decorated with chocolate and would fall into the Standard rate for VAT, are zero rated because they are in fact cakes.

Hot take: speakers at conferences which will have a bigger video audience than in-person audiences should sit down. Even if most of the split screen is the slides, wandering around, kicking your feet and gesticulating is distracting and achieves nothing.

error handler function, back up one level.

error handler function, back up one level.
called function picks up file and line as variables and passes them on to a handler function via a pointer.
You can't avoid this by using __FILE__ etc in this function, or all calls will give the same values.

Error handling with callbacks and line numbers in C.
If you put the __FILE__ and __LINE__ macros in the called functions, it will not show you the caller function location. Need to use a macro which wraps the function and passed params on, & adds these macros.

If you want to find the shortcut for a command in VS Code, you can type the name of the command, but if you want to reverse look up the keys to see what the command is, you can click the keyboard icon on the right in the search bar and then type the shortcut keys.
Ctrl-K Ctrl-S brings this up.
