    OK, what hardware are you talking about?

Question: the jsfx function file_string(handle,str) seems to only read the first line of a text file. The description says that the string can include newlines. Would I need to encode or convert a text file made with (for example) notepad in a certain way? or is this a limitation? [permalink]

    Depends on what you want to do, but SetWindowText(mywindow,"my_utf8_string") should work as-is. Some controls require installing a hook for each control (e.g. WDL_UTF8_HookComboBox()), owner data list views are a bit trickier...

    I have been told that I look like shaggy, usually when I need a haircut.

Question: Hm, a can clearly see how Reaper distributes Reason to 3 cores and Nuendo uses only single core. This is A situation, when it works, but you don't know why, haha. [permalink]

    Hmm OK if you say so!

Question: Sorry, I know this page is not for REAPER API questions but I don't get replies in the dev forum and this question is very essential for the next version of my Playtime plugin: Is it possible to use a custom PCM_sink (already implemented) for recording MIDI - not audio (so REAPER calls the WriteMIDI method)? If yes, how? :) [permalink]

    Not possible at the moment, though maybe I'll add such an API at some point.

Question: Totally agree with whitespace vs tab issue! There is, however, a silent agreement in the Python community to never use tabs and always use 4 spaces. I think I only once stumbled upon code that did not follow this convention. But technically you are right of course. Concerning % in vi, did you know that you can do this in Vim: [[ ]] [m and ]m?

    I knew [[ and ]], but didn't know [m, that's nice

Question: I always tought that Rewire is limited to single processor core. This is my experience using Cubase/Nuendo and Reason combo - CPU performance in Rewire mode is pretty bad, comparing to running Reason in standalone mode. But now i've just discovered that Reaper is spreading Reason processing over several cores. How in the world is this possible ??? Am i miss [permalink]

    Hmm it can only use one core at a time, but can be passed from core to core, I think.

    Not sure how it would, but maybe for live performances? uber-concert-experience...

Question: Yes, whitespace is for programmers. And then you need to use something else in addition, just for the compiler. Wouldn't it be great if the compiler just understood what you are using anyway? :-) [permalink]

    I'd prefer it be explicit (also % in vi is great).

    Also there becomes ambiguity when spaces and tabs are mixed, and what about with ambiguous whitespace changes?

Question: You mentioned your discomfort of the importance of whitespace in Python multiple times. Seeing you using indention etensively in your non-Python code (where it is not needed at all), it seems quite important to you, too. What am I missing? [permalink]

    I wish I had a good answer here, but most of what I learned was 15-20 years ago, and it was a different world then, documentation was hard to come by... so maybe look at various open source projects? Sorry to be of so little help.

Question: If your wealth suddenly went away and you had to go back to regular apartment living with your wife on a 70k/yr income, do you think your happiness would significantly change, or have you learned money doesn't move the needle as most people expect? [permalink]

    How do you know I don't live in a "regular" apartment anyway? I don't think money makes much of a difference, once you get above a certain point. I'm not sure where that point is, and it varies a lot with geography, but yeah I'm sure I'd complain. Having said that, if I had to work a job that I didn't find interesting (vs getting to write music software), I would think that that would have a big effect (though maybe not what I think, since perhaps it would make the hobby time writing code that much more enjoyable).
