Hello Linus,

You're still a genius with this one. Repeating the same screen row, switching just the charsets(banks) and color registers to create the illusion of panning thru the tunnel with sprite masking in the middle.

Good job,

It is fantastic and very creative. Congratulations, you are great!

Kernighan's lever

From a very recent experience debugging complex but old multithreaded C code, which was not particularly clever, I can say that quality should be measured through clarity first.
The only way to maintain obscure or overly clever code is to expose yourself to it, to instrument it, to be humble about what you do not know, and eventually it will be understandeable.
To avoid having to go through such pain, it would have been better to use some clear patterns, like state machines, or good mutex hygiene, or well-tested and dcoumented and named C macros that do one thing well and reliably.
Unfortunately the code was not clever, it used lots of if's, very long chains of them, and simplistic approaches to threading that did not factor commonalities.

Code can be clean, mathematical, clever, so long as it builds on itself, like lemmas towards proofs. Staying flat and simple can be problematic sometimes as well.

I get Kernighan's comment, and I think clever means tricky, like using bit twiddling or taking advantage of peculiarities of the machine or language rather than letting the compiler do simple optimizations.
Thompson wrote something similar about preferring the straighforward algorithm to the overly optimized obscure one in most cases.

159 moves! No wonder I couldn't work it out. Did you do that by hand, or with a solver?

153 !!!!!!!

Hi Linus, just some few words to thank you for your hardware chiptune tracker that we used for making the Gamebuino sing for our tiny demo GbFx https://www.pouet.net/prod.php?which=105576
