It's the weekend, baby

Across most of the emulators I've studied ensuring the timing of the emulated chips lines up correctly has consistantly required some care, but nowhere more so than for the Super Nintendo Entertainment System! So BSNES bundles a cooperative multithreading library "LibCo".

The core logic here is CPU-specific (implemented for AArch64, AMD64, ARM, PowerPC, PowerPC64v2, SJLJ via UNIX signal handlers, & x86) writing all registers to one pointer whilst reading them from another.

1/2?

Weirdly LibCo implements these in machine code rather than Assembly code, and takes care that this code can only be read/executed. Also (de)initializing threads is CPU-specific in terms of how much RAM's required.

Also it can defer to Windows' Fibers library, or POSIX's UContext library. I'll note that ARM has a particularly easy time swapping threads, only a couple opcodes!

Turns out that LibCo is all ports, no machine/kernel generic code!

2/2 Fin for today!

Woot! I got approval to go to #FOSSY2026 and I'm looking forward to the #Fedicon track. I'm all in on the open social web!

Do you have a favourite invertebrate and why is it the velvet worm? Of course it is. https://www.theguardian.com/commentisfree/picture/2026/jul/10/we-say-thanks-to-all-our-selfless-spineless-pals

I just had to confirm to my washing machine that I'm over 18

This is part of my "slightly better photos of local attractions than you'd typically find hanging in your hotel room" series.

"The city seen from the Queensboro Bridge is always the city seen for the first time, in its first wild promise of all the mystery and the beauty in the world."

- F. Scott Fitzgerald, The Great Gatsby.

This was captured with the Phase One IQ3-100 back, Phase One XF DSLR camera, and the Schneider 80mm/2.8 "Blue Ring" lens. I had planned to use a technical camera and the Rodenstock 70mm, providing movements, but a cable was missing from the kit I had with me in the city that night. Fortunately, the 80mm SLR lens was just wide enough to not require movements, though the Schneider lens renders highlights (as prominent starbursts) a bit idiosyncratically for my taste.

Officially the "Ed Koch Queensborough Bridge" but more generally simply the "59th Street Bridge", the view from Sutton Place at 58th Street on the Manhattan side is probably as flattering and uncluttered a perspective as you'll find for this piece of NYC infrastructure.

Immortalized in song by Simon and Garfunkel, in literature by Fitzgerald, and in cinema by Woody Allen, something about this bridge exemplifies the glamor and bustle of 20th century New York in a way that still holds up.

Queensborough (59th Street) Bridge, NYC, 2019.

A different bridge from the one over troubled water, though the East River shouldn't be trifled with, either, at https://www.flickr.com/photos/mattblaze/48418025131/

Yes, once the first release is tagged, I plan to work on a YunoHost package.
@yunohost

#HolosSocial relay is confirmed to be very stable. I will officially tag it soon so admins can run their own relay with a script to easily install it on their VPS.
Using Holos with a custom domain and a cloud for media allows you to own your portable identity on the #Fediverse. Relays become only an infrastructure for it. Your device runs the #ActivityPub server and works as smoothly as any other app. Micro-blogging, media, and video, all from a single account. Switch with a simple tap.

Ladies and gentlemen... the weekend. (also: you are important and are not alone 🧡)

it is your human right to vent as needed i need no apologies

Don't know about you, but feel like we really dodged a bullet, and excited to hear from an amazing bunch of great progressive candidates campaigning to be the next Senator from Maine. It's been a bumpy road, but optimistic it will turn out for the best so long as the national Democratic Party operatives are kept at bay, and seems like we can trust Mainers to do that. Things are looking up.
