Nice write up about Deluxe Paint:

Also in the later years Deluxe Paint Animation on PC was cool.

Willow performed a standard benchmark computation in under five minutes that would take one of today’s fastest supercomputers 10 septillion (that is, 10^25) years — a number that vastly exceeds the age of the Universe.

I was wondering why rust-analyzer does random hickups and switching to lld finally fixed it. The choice of linker inherits from matching Rust environment of macOS, which does use LLVM ld, and never experienced similar glitches. This even happened sometimes with 9950X desktop.

So for any Rust installation in Linux I'd first and foremost always add this to .cargo/config.toml before anything else:

[target.x86_64-unknown-linux-gnu]
linker = "clang"
rustflags = ["-C", "link-arg=-fuse-ld=/usr/bin/lld"]

Installation:

1. In Fedora: dnf install lld
2. In Debian: apt install lld

AFAIK, by de-facto it probably uses GNU ld, and also some flashier newer ones do not provide glitch-free result with rust-analyzer (i.e. mold and wild).

Hmm... I get weird subprogram names from DWARF with RV32E/RV64E on RISC-V rustc.
Or like, each have the exact same symbol name o_O.

Takes some time to get a test for my "FUSE camera driver" right (it's like in ~65% done til RFC) but one additional application that came to mind for it would be provide camera access for Wine ("winecamera"). So that you could use Windows applications, which require camera access.

Video streamed with ffmpeg, and played with ffplay through with my WiP V4L2 loopback driver.

The next step is to detach the producer from /dev/videoX fops and instead return anonymous inode, which owns a file where the capture device can write the video stream.

The video resolution in this smoke test is 640x480, and the encoder scales it up in real-time to 1280x720.

I like in Rust how it returns back to MS-DOS on in executables and libraries ;-)

No joke. Makes debugging so much better experience...

DSO's suck... (for most part unless they are actually needed).

IPv4 Internet of today

I wonder whether 2025 will be the year of IPv6.

I miss 90s and dialup as then you could actually speak to another computer no strings attached...

In some ways Internet was more advanced in tech back then ;-)

Learned something pretty basic but also somewhat essential in software and systems engineering, i.e. how to switch the default linker in #Fedora :-)

PS. Needs sudo in order to make an effective change.

Saku - Suomen Amiga-käyttäjät

Wallun Mikrokivikausi-näyttelyn avajaiset Tekniikan museosta vuodelta 2016 – video pullahti YouTubeen tuossa reilu viikko takaperin. Tähän näyttelyyn perustuu myös Mikrokivikausi - Kun esi-isä tietokoneen osti -sarjakuvakirja, jonka (vielä myynnissä oleva) 3. painos on painatettu yhteistyössä Suomen Amiga-käyttäjät ry:n kanssa. Videolla esiintyy myös Wexteen, aka Jyrki J.J. Kasvi, joka oli toinen näyttelyn kokoajista. ❤️ https://www.youtube.com/watch?v=xJmoJ0e3Nxw

Trump's appointees are basically incompetent ideological henchmen, or billionaires. And there's some overlap in categories.

#Flatpak would be much better if #Flatseal functionality would be somehow embedded nicely straight into #GNOME settings. Lack of such functionality out-of-the-box is the main glitch of the Linux app ecosystem for me.

I would take the reference from privacy and security settings of macOS. Flatseal is pretty much the same deal, isn't it?

"A Short History of the 303 in 12 songs 🙂 How the 303 failed successfully - our fav TB-303 patterns"

https://www.youtube.com/watch?v=kf2-WLK3gPA

Personal trivia: the oldest noticable 303 song I know is "Let me go" from Heaven 17. It came out 1983 and 303 was discontinued 1984 (manufactured 1981-1984, it was a commercial flop).
