Question: In some programming languages, like C#, Python etc. We can't directly take int/float as input from user. Instead, we take string from user as input, and typecast that input into integer or float. Why can't we directly take int/float as input from user?

I suppose that's a decision made by the developers of the language! I mean, in theory you could take raw bytes from the user and interpret them as IEEE-754 floating point, too? I guess the default mode of inputting anything is a string, and then converting that using the cast (which implies parsing the bytes as a floating point string...) makes a certain amount of sense? 2 Comments...

Question: How about a black theme for this website? It's night and dark here, and the white background is bright for my eyes, haha. Maybe you just have to invert the colors?

Question: ListView redraws itself when it's offscreen during a move operation making the window a little bit sluggish. In the past I have solved the issue tracking WM_NCLBUTTONDOWN, involving an ugly hack. What would be a better approach? Thanks

Question: Is it possible at all to aggregate multiple audio devices in Windows on ASIO, not WDM? Could Reaper do it although system does not support it?

Reply on December 18 2022, 10:19pm (edited at December 18 2022, 10:20pm):

REAPER could probably do it, but the performance would likely be lousy as we'd have to synchronize threads for each device (since ASIO involves each driver creating its own processing thread). 2 Comments...

Question: How is the state of things with REAPER and Intel CPUs gen. 12/13 regarding the efficiency cores? Remembering your blog post you had to do some tweaking in the REAPER code for the M1 efficiency cores.

Reply on December 18 2022, 9:32pm:

I haven't looked at it on Windows, a lot of it will depend on how the OS schedules things; a lot of the issues on the M1 was due to the way that Apple exposed the thread scheduling to applications. On Windows it might be a non-issue. 7 Comments...

Question: If you could just copy and paste the whole REAPER source code to a GPT AI chat bot (maybe the upgraded version 3 years from now) and just tell it: add this, do this here, it should be like this, giving priority on that and so on then it spits out exactly that and it works perfectly as expected.. would you do it? Or you just enjoy coding, or maybe a little of both? Like letting it help you on your journey?

Reply on December 18 2022, 8:08pm:

I definitely enjoy the process but I also enjoy making my life easier. I wouldn't be opposed to it, assuming the bot could do it with 100% correctness, but verifying that would be easier said than done? Comment...
