Question: What's the most complicated algorithm you've ever solved, one that perhaps took days of just thinking and trying ...
Asked by Will (70.173.150.x) on January 9 2013, 4:34am
Reply on January 10 2013, 2:32am:

Hmm the more difficult things are of higher complexity, generally -- i.e. figuring out the combination of many algorithms needed in order to make something work, and getting them all to play together. Usually once you do that and have things work, then you can refactor any given part in order to improve efficiency etc.. Sorry for the vague answer, but really the timesink is higher level than just "an algorithm." Comment...

Question: On a scale from 0 to 100, how would you rate Reaper today in relation to how you want to get it finally some day?

Hard to say, was 0 where it was where it began? It's been about 7 years now, who knows how long it'll go... Comment...

Question: Why is the developement of Reaper so slow lately? Motivation issues? Boredom? Lack of inspiration? My deceived perception?

It may not be quite as slow as you think, but if it is a bit on the slow side it's probably due to the holidays more than anything. Comment...

Question: How do you convert timesig value in TempoEnvEx to num and den? For example, why is 12910593 equal to 1/197? Thanks!
Asked by Martin (93.136.113.x) on January 6 2013, 7:38pm
Reply on January 6 2013, 9:23pm:

The numerator is the low 16 bits, the denominator is the high 16 bits, so 12910593 is (197<<16)+1. Comment...

It's rare you are in a bar and someone is like "here let me program this...", but even if there were, no programmer would ever be like "here let me do that for you" to someone they didn't know extremely well. It's just not done. Comment...

That V8 code is way more awesome than EEL.. EEL is kinda small and crappy in comparison. Comment...

That's pretty awesome, though some of the logic in Probe() (changing _supported to various states during the construction of assembly code) doesn't make total sense to me... Comment...

Hmm yes we could change the way ifdefs are used there for clarity's sake, no doubt. Comment...

It sort of has support for that, but it is unclear whether it would provide improved performance unless all primitives supported it... Comment...

Where are there so many #ifdefs? For something like ANSI/Unicode it would make sense -- mostly having things use LPTSTR etc, and a few spots requiring #ifdef too. Comment...

Question: is it possible for a win32 unicode app to use swell out of the box?
Asked by gio (94.66.93.x) on December 27 2012, 10:54am
Reply on December 27 2012, 9:40pm (edited at December 27 2012, 9:42pm):

Not really -- SWELL is a small subset of win32, but also it targets UTF-8 rather than WCHARs... Though I suppose we could make it do WCHAR pretty easily via #ifdefs, but that'd be a decent bit of work. In either case, though, it takes quite a bit of work to target SWELL vs Win32, and even then there is platform specific work when targeting OSX vs Linux etc. Comment...
