Absolutely, I use raw Ninja for all my personal projects. The only support I miss is globs, as the Ninja files are quite redundant without them. In some of those cases I use a few lines of Python to regenerate a list of Ninja targets.

Oof, while it's nice to see documentation, that pdf is clearly not done yet. A block diagram with one giant block labeled "Bus Fabric" is not so helpful, and all the I2C/SDIO/etc interfaces are just tacked on to the

It does have one PIO block. That datasheet does not look finished yet.

The first sentence of the wikipedia entry is literally "Graham Bruce Hancock (born 2 August 1950) is a British writer who promotes pseudoscientific[2][3] theories involving many ancient civilizations and lost lands."

Yep, and if you're playing with your own homebrew OS or other non-linux OSes you don't really need all of OpenSBI - implementing the equivalent of putchar() and a few timer calls will get you up and running. (Source - did bring up

Trying to definitively prove masks "helped" or "did not help" would require comparison against a control Earth where masks were never used.

This was a disappointing article. I found quite a few incorrect statements, and the overarching claim that "space inside an atom is full of clouds" isn't going to be particularly convincing considering that clouds are also...

Misread as "for quitters", imagined a language that gave you encouraging messages for each syntax error. "I'm sorry but 'printhrglf' is not a function. You're doing so well though, keep trying!"

MurmurHash author here, looks interesting and I will take a closer look later today.

I built an 8' wide spherical display out of an advertising balloon, a hemispherical security mirror, and a conference room projector. Then I wrote a 3D engine that could render to it and took the whole thing to Burning Man. Worked pret

I can parse all of GCC's C torture tests with basic UTF8 support in my "toy" PEG-based parser, does that count?

Learning for the sake of learning is vastly less impactful than learning for the sake of accomplishing something. As I've gotten older, the scale of the personal projects I've been willing to take on has grown exponentially, and m

Oh man, the soldering job on this _hurts_ me, and I've done a lot of hand-soldered 0201/QFN stuff. If you're reading this, _never_ thin out your solder paste with flux. You're better off dabbing tiny bits of it onto the

Rough guess - CSGO on one monitor and web browsers on the other monitors would be OK, four 4k videos would probably not be ok. I looked up the specs for that GPU and they're roughly 1.5 teraflops compute and 20 gigapixels fill rate, so

by aappleby 3y ago
Integrated GPUs have had sufficient fill rate to composite 4x4k pixels for a while now. 32 million pixels * 60 fps = 1.8 billion pixels per second, which is a lot but even integrated GPUs have compute measured in teraflops now. Memory bandw

If I ever write Murmur4 it's going to be the smallest function that I can prove (via sat solver) to have no seed-independent collisions :D

Murmur author here, it is a lot of trial and error but in general you're trying to pack as much "nonlinearity" as possible into as few instructions as possible. Multiplication is commutative, xor is commutative, but if you mi

23 megapixels total, or about 3 4k monitors worth of pixels. Should be super clear.
