I'm about to compile it for the 8-bit ATmega2560 (on an Arduino 2560 mega board)

Here's the result on a little ESP32 wired to an SD card using the junk built in SD library (SDFat is faster)

You need to get your hands on that server that LTT was showing on their video yesterday. It was a 128 core, 2TB ram with raided nvme pushing through 30GB/s under Windows and knocking on the door if 100GB/s on Linux.

Take heart. We all have to start somewhere.

What I'm doing to make it fast isn't even all that complicated. It's just combining two of the right things - in this case, memory mapped files w/ strpbrk()

Sometimes coding isn't about how "good" you are. As often as not it's about being in the right place at the right time. Half of the "good" code I write practically falls into my lap. The rest of the time I'm writing buggy garbage.

Big Grin | :-D

Musical adventure trip

Early I posted some links to some music on youtube. As it often happens, one click leads to another and I ended up with the BGKO Barcelona Gipsy balKan Orchestra[^], in concert.

It's good background music, but what a strange surprise: they start of with Klezmer. Yet, come to think of it - not that much a surprise - both music's are from people that travel/are driven around Europe. The improve from both cultures - well just nice music to work by.

[edit/suppliment]
And I wandered on to the didgeridoo - including how to make you own and the basics of blowing Gabriel's other horn. Hypnotic. Also, sounds like a good background theme for hunting management for later stuffing and mounting
