God, that's the worst. Minecraft is also what led us to accidentally bind my child's account to the administrator account on my TV PC, and because he's a minor we can't actually unbind that account. I've tried for h

I write Rust for embedded systems and both effects and linear types would be meaningful improvements. Effects especially: if you have multiple cores in a coherent memory domain AND you run with interrupts enabled, you have to deal with thre

Every time this conversation comes up, I'm reminded of my team at Dropbox, where it was a rite of passage for new engineers to introduce a segfault in our Go server by not synchronizing writes to a data structure. Swift has (had?) the

Windows 95 allowed programs to disable system interrupts. No protection on cli instruction. Careful with those rose-colored glasses.

WER existed on XP but the APIs needed to customize dumps didn’t. And IMVU’s crash reporting code dated back to 2005. > So I think that the claim that Direct3D captures exceptions is suspect. I would think that too - but I based my claims

Hello, author here (16 years ago). I don't think that component existed then. In hindsight, we would have either used WER or initiated crash dumps from outside of the process via a watchdog. It is quite problematic to attempt to captur

It did, especially as the drives got older and shrieky. Plus the floppy and optical drives spinning up. But... funny story, when I moved to Silicon Valley, SSDs didn’t exist yet, but compile times were IO-bound. So my company bought everyon

Looks like ‘97. Unfortunately I can’t find the receipts! If I had to guess, I think I’d say somewhere around $2000 in all. That computer lasted me a LONG time. When it was done being a desktop, it became a Linux server until I sold it aroun

I did a bunch of media and software development back then so RAM helped a lot. Why 640? Not sure. My particular board could have gone up to 768. I did some googling and found some boards that maxed out at 1 GB. That was a weird time in comp

You are straight up wrong. The first computer I ever built was a Pentium 2, RivaTNT, and it had 640 MB RAM. I can’t find the purchase receipts or specific board brand but it had four SDRAM slots, and I had it populated with 2x64 and 2x256.

Last Christmas, we got a tree from a local farm in the mountains. We had the tree trimmed and decorated before we discovered a sleeping (hibernating?) bat on the inside. We got it moved outside, but it took about 24 hours before I realized

I'm sorry, I had a whole section on amortized allocation in a draft version of the post but I deleted it, thinking it was tangential. You're not the first person to ask: https://www.reddit.com/r/rust/comm

You can still put atomics outside the mutex in Rust.

Exactly correct. Loading solarized in 256-color emacs shows just how poorly the (carefully-selected) Solarized colors map onto the xterm-256color palette.

You're right: I should have included COLORTERM in this history, and a couple of the other fits and starts, like the `RGB` terminfo capability. The issue I had with COLORTERM is that not every program respects it. In fact, I've had

Where does this “can’t see more than 60 fps” rumor come from? It’s trivially refutable by placing a 60 Hz strobe (e.g. old fluorescent light or even some aftermarket headlights) at the corner of your vision. Also, for interactive systems, 1

I appreciate your reply! My approach has been to send a header with the number of fds and bytes the next packet will contain, and the number of payload bytes is naturally never 0 in my case.

I was also surprised by how suboptimal avr-gcc's generated code is. On the other hand, the AVR experience is reminiscent of early DOS, terrible C compilers and all, so it remains nostalgic! Two examples: https://gcc.godbolt.

EdenFS builds (and probably runs?) from GitHub, but we have done no work to make it usable and hook it up to an existing checkout. It may not be much effort, and we're hoping to demonstrate that workflow in the future.

20 KW sounds way above average for a single home. $1 / Watt sounds about right, though.

Part of the issue is how unevenly distributed the money is. Look at slide 7/8 in https://www.cusdk8.org/cms/lib/CA02218495/Centricity/Domain/... $8,200 per pupil in Cupertino, $24,700 in Woodsi
