The most important algorithm in the world, matrix multiplication, just does a fused multiply add on the data. Memory bandwidth is a real bottleneck.

How long has that even been a regulation and in which countries does it apply? Software engineers are trained to view these kinds of things as bugs. Legal isn't trained to monitor bug trackers.

Are you saying io_uring is basically IOCP for Linux? If that's true, then I'm not happy about it being in the kernel. IOCP only goes 2x faster in my experience (vs. threads and blocking i/o) and that isn't worth it for t

It's not even a very good padlock. Using Cloudflare makes you powerless to stop level 4 DDOS attacks, because Cloudflare isn't very good at preventing hackers from abusing their service as a means of amplifying them. If you'

I don't think so. OpenBSD 7.3 works great. Their latest release broke APE in two ways: https://github.com/jart/cosmopolitan/issues/1263 I'm not sure if something like this is an accident. We might n

A lot of quants just upcast to floats. Some of them work on integer multiplication using pmaddubsw. But oof, it looks like the i4004 doesn't even have that.

Multicore is a pretty big functional difference. Like attaching an automobile to a wheel lets you have three more wheels.

That issue may very well be solved. We added C++ exception support shortly after that issue was filed. You may want to try https://github.com/jart/cosmopolitan/releases/tag/3.9.2 and see if it still impa

Well these days cosmocc -mtiny is more like 120kb, now that our binaries support ARM platforms too (like Android!) and all the code I've needed to add to make sure Cosmo works reliably for a longer tail of edge cases. But that's s

I know bro. Last time I was walking down fifth avenue, I saw Richard Sackler getting a dirty water dog and I was so trembling with fear of that gangster that I dove into a manhole cover.

Wonderful. I can't see how a society that stops believing in individual responsibility is going to keep believing in individual autonomy too. We've been seeing the same cultural shift in technology. SB1047 in California seeks to h

Yes but the Sacklers would have no income if they're languishing in jail stamping license plates. That means less money to pay the people who brought cases against them. Think about it. Liabilities don't just take their wealth, bu

They have been. The Sacklers are social pariahs and outcasts. Their liabilities far exceed their net worth. They had to move away from New York to Florida in order to afford something resembling their old lifestyle. Their family name has be

I watched the Netflix series Painkiller five times in a row. I watched the entire Sackler deposition. My heart goes out to the people who have lost loved ones. I simply disagree with the anger and outrage.

Only if you believe people aren't responsible for their own actions. Pintos would explode when you're rear-ended due to fuel tank defects. Opioids won't kill you if you take them as your doctor prescribes. Cars in general are

If there isn't enough power, then why don't power companies just make more power? Why is it the tech industry's responsibility to consume less resources?

My project is literally to make a compiler toolchain. Do you expect me to not use it? The nice thing is that you can build my project on any computer that has modern GNU Make. That and sh are the only things that needs to be installed.

My Makefile is portable. It builds binaries that run on six OSes and two architectures. So I used my Makefile to build GNU Make and a GCC toolchain. Now I can run my Makefile on any of those OSes / architectures too, and it'll pro

I work on a project with 4.4 million lines of code and using a single Makefile with no generated code works fine. It's really not all that difficult.

Don't be discouraged by all the people in this thread saying you're using make wrong. One of the things that makes make a great tool is how deceptively simple it is. Yes not using .PHONY can potentially get you in trouble. But for

Government agencies have got their hands tied just getting people to use MFA and not click on phishing emails. You're decades ahead of the herd if you're thinking about coding in SECCOMP-BPF.

If a userspace process can't tell, then does it really matter? That's what qemu user teaches us. The Linux ABI is simple enough that a single dev could emulate probably 85% of it in pretty short order. What keeps Linux going is th

That's kind of insulting honestly. Getting Linux to run on an i4004 is bona fide engineering. More real than engineering that we're paid to do most times. Looking at the list of Ig Nobel Prize winners it sounds like The Onion but

There needs to be something like a Nobel Prize for this kind of thing.
