I just made llamafile 1.3x - 5x faster than llama.cpp on CPU for many prompt / image evaluation use cases and hardware. justine.lol/matmul/

Did everyone else already know atomic increment/decrement etc. come with a full memory barrier on x86? I’m surprised but I guess that helps explain why atomic reference counting is so bad. stackoverflow.com/questions/5032…
Hey #plottertwitter, I got a HP 7475a recently, but the carousel is missing. What's the best way to get one?
Excited to share that Better Transformers got integrated in @huggingface Optimum library to bring major speedups for many of encoder models on different modalities (text, image, audio). better_model = BetterTransformer.transform(model) One line to run your model much faster!
Catching up: fastmod is up to v0.4.3 as of last month. Since 0.4.0, changes include several crash fixes, better color scheme compatibility, —hidden for searching hidden files, and picking up security fixes in dependencies. github.com/facebookincuba…
With PyTorch 1.12, we're releasing Better Transformer. With no code changes and fully compatible with existing trained models in Torchtext, we observe 40%-2x+ inference speedups on BERT on A100. Read more: bit.ly/3aAKQj8
32 muted words in, “more words to mute” is still the highest signal thing coming out of my timeline.
How do I get Twitter to show me only the tech stuff? I have an interest-specific second Twitter account and it’s pretty high signal-to-random-stuff ratio; main account here is mostly random stuff so I don’t read it much.
Today in time-consuming typographical errors: ++begin, +ii
Yesterday I wrote array[1] instead of array[i]. Bad time finding that one.
Last time DC tried Internet voting, in 2010, it took my team 48 hours to hack in and change all the votes. There haven't been any breakthroughs that make online voting fundamentally more secure today, and threats elections face are even more dangerous. youtube.com/watch?v=LaR7n5…

I just published General Guidelines for Software Performance Engineering in C++ link.medium.com/SZQvpvhVNIb These are some general guidelines for C++ but actually they are pretty generic practices/approaches. They might end up in the C++ core guidelines in some form. We'll see.

Quoted for endorsement. (Read “routine” as “You do not have to bitten by a radioactive spider to generate this outcome. Most people who achieve it will not be nationally known within their industry or to people on the street.”)
if you are a late career software engineer it is somewhat routine for you to be in the seven figures of compensation with most of that being stock in your company.

@lefticus Sure, that can work. However, the real problem here is the wishful thinking that we’ll be able to meaningfully carry on a GUI desktop for the user while the system is unable to accommodate a 3-byte malloc.
I'm trying to figure out what I'm even supposed to add, and this seems like a possible start. Maybe what people need to hear is not that nanotechnology is possible, but that bacteria are possible.
