Spent most of two days changing gammakit to have a static lexical scope model rather than emulating lexical scope at runtime. The motivation was to try to bring down the runtime of a 5000-iterations "nbody" demo down below 0.32 seconds, which is the time that demo has on my computer when run in Game Maker 8.0's version of GML. Gammakit is superficially very similar to GML, but way, way, way more powerful, so GML is the most fitting comparison.

After those two days of work, with many aspects of the language currently on very shaky ground, I'm happy to say that I managed to bring the 5000 iterations nbodies demo in gammakit down from 0.75 seconds to around 0.5. Yep. That's it.

Gammakit performs zero real optimization in the process of converting source code to bytecode. There is no analysis of variable accesses or anything like that.

Up next: trying to eliminate "ValRef", a mutable smart pointer that is probably itself another performance hole.

Hmm, between v108 and v109, full screen screenshots using Print Screen stopped working with OpenGL 3.2 on Windows 10. v108, I get expected image, but in v109, just get a black screen. Anyone else seeing this?

No idea, but this seems like something I would probably consider a windows bug. Worst case scenario if this is never figured out is to use something like ShareX instead.

I'm feeling too lazy to do any real explanation of how I'm learning and what kind of equipment I'm using, but as of a couple months ago, I've started making "Real Music". Like, stuff played mostly on real instruments (except the drums). (Not an attack against electronic music; just an indication that I'm not making Midi Metal). Stuff that wouldn't be embarrassing to print on physical CDs and sell at independent music conventions. I mainly post it to my current soundcloud.

The style is probably somewhere between hardcore punk and post hardcore with random stylistic inspirations taken from progressive metal.

Touhou stuff:
Beyond The Last Boundary
アノ都市伝説ニツイテノ検証 (An Outlandish Truth) (this is the Real Shit but it's largely spliced together lol I suck at guitar so much)

Non-touhou stuff:
地獄があるなら一緒に� �ちてやるぞ (You ain't goin' to hell without me) (sounds like crap since I wasn't sure how to into Guitar Amp/Cabinet Simulation yet)
Take Me Down (warm day demo) (sounds fine because it's just DI recording)

Anyone else make music? My music making goes a lot further back but it's only just now that I've started being Good.

That's not what exonerated means, and there's far, far more to the situation than "russiagate".

Pretty sure the public sphere doesn't consider the Orange Bad Guy to be innocent of anything in particular.

Your "hard numbers" are just random references to the news cycle. When the news stops talking about something that doesn't mean people stop caring about it. People talk about Trump's general corruption all the time. They're even trying to connect him to Epstein. The moment that Russia comes up regarding him again it'll be all over the place. You're also assuming that the Mueller report had a very narrow topic.

You are incredibly uncritical of yourself. It would do you a great deal of good to not develop such strong opinions and to pay more attention to how events flow into one another instead of just taking snapshots and taking permanent stances on them.

I decided to go through with making something that resembles an actual release with the two touhou tracks I made. The mixing/mastering is slightly different. No price tag and I stuck a random third track in the download.

A mistake. A big, fat, huge mistake. The sRGB gamma curve should have been defined as a fixed exponent of 2 so that conversion between linear and gamma-compressed space was trivial, and so that it was different enough from displays that graphics vendors were required to actually convert if their monitor didn't actually follow the sRGB gamma curve.

Something like that. The worst part of it is the linear part of the gamma ramp, which just means that people implement it incorrectly (because an exponent is Good Enough™). The general idea is fine. If we're only storing 255 brightness levels per channel we should DEFINITELY gamma-compress them. The question is how much, with what curve, and how the representation is chromatically defined.

It's an electric piano! (i.e. it's just *supposed* to sound different. for example, electric keyboards had much softer harmonics and harder/cleaner attacks (no hammer noise) than real pianos for a long time, so jazz groups preferred them based on sounding less harsh when mixed in with tons of highly dissonant stuff, as jazz goes. same reason jazz guitarists generally play with very relaxed tone.)

I wish there was a tag for "I know you know this or it doesn't matter whether you know it or not but I just want to say it for no particular reason at all".

I wrote a proper writeup of how gammakit was designed the other day. If you want to make your brain hurt, go ahead and give it a read.
