And now GLD with its 1 year return at 40% is outperforming them both, which is a really scary thought. How bad do things have to be, that all our blood sweat and tears scurrying off to work each mourning earns less than a piece of metal dug

You mean VFIFX? What a disaster. My retirement plan put me in that until I realized investment advice for young people is a tax on the inexperienced and vulnerable. VFFSX (S&P 500) does 2x better returns every time. I feel guilty saying

Hi troad, I read your book: https://justine.lol/sectorlisp2/troades.html I don't remember saying that. You might be thinking about https://justine.lol/ape.html where I said we should be focusing o

I never would have been able to understand lambda calculus well enough to write the blog post if I started with [0]. I say just pull out the shell and start coding things. Then read [0] later to appreciate things on a deeper level.

I can't think of a faster easier tool for composing and controlling a bunch of heterogeneous things. Even if you write a Python script that does it, you're still using shell to run it. Notebooks are good for experimenting and expl

I put gnuplot code and python code in my shell scripts all the time. Someone like you should think of it as a jupyter notebook that doesn't need a web browser.

Why can't they just take a class on shell scripting? The whole point of computer science is to automate things, because that's what gives you leverage. If you don't care about understanding computer science, at least skip to

If I'm reading this thread correctly, it sounds like truckers staged a protest in Canada blockading roads. The government couldn't move the trucks because the cops sympathized with the protestors. So the government debanked the tr

I came here to basically say this. io_uring is a leap into the past. It's going to be blocked in a lot of environments since it makes system calls unmanageable. Now mmap() on the other hand is a real enlightened system call. I got prob

It's the stated mission of my project. Rust's stated mission is memory safety. So using raw system calls is a distraction for them.

System calls take 10x longer on Windows than they do on UNIX. That's what i/o completion ports are working around. They solve a problem UNIX doesn't have.

Rust isn't standardized. Last time I checked, everyone who uses it depends on its nightly build. Their toolchain is enormous and isn't vendorable. The binaries it builds are quite large. Programs take a very long time to compile.

This kind of error is a right of passage with WIN32 programming. For example, to do nontrivial i/o on Windows you have to create an OVERLAPPED object and give it to ReadFile() and WriteFile() which will return a pending status code, an

No the solution isn't to rewrite it in Rust. The solution is to have the option of compiling your C/C++ program with memory safety whenever things go loopy. ASAN, MSAN, and UBSAN are one great way to do that. Another up and coming

Well at least American telecoms are fighting them. The European MO is to not only let themselves be conquered, but they actually pay China to do it. Thankfully American online services are on Europe's side, and work harder than anyone

Where do you think government policy comes from? If the people who are smart and wealthy enough to torch half a million dollars on original independent research care more about who's breaking the law rather than what's true, then

I love articles like this. If you want to see a tutorial on how you can take this a step further, by creating a tiny ELF file that runs on Linux, FreeBSD, NetBSD, and OpenBSD 7.3 then check out https://justine.lol/sizetricks
