My wife and I recently discovered a bum gun in one of our bathrooms at home. It gave me quite the shock!

I've added a fullscreen option to my Apple II video player, for completeness. However, there simply isn't enough bandwidth for it to be enjoyable.

The Matrix rooftop scene, in fullscreen on the Apple IIc's screen. There are, on average, 7 frames per second.

@colin_mcmillen@piaille.fr avatar

@santiago TBH, I thought about it. Either a black line, or interlacing. But so far, I didn't even test it, because I think it'll look bad - and also, displaying half the lines only halves the bandwidth, whereas going from my usual size to fullscreen quadruples it; so that probably wouldn't be enough.
I should test it just to make sure.

colin_mcmillen,
@colin_mcmillen@piaille.fr avatar

@santiago You made me curious, I tested. It's much better than I thought it would be... Considering leaving that on in fullscreen mode. I'll do more tests :)

The same video, but only 1 out of 2 lines are displayed. This is remarkably not noticeable, and gets the framerate to 16fps

colin_mcmillen,
@colin_mcmillen@piaille.fr avatar

@santiago I wonder. It's a bit more work - right there, I can do it in the decoder; for proper interlacing I'd have to do it in the streamer, to account for dropped frames.
Also I suppose frame drops may become more noticeable if the interlacing speed decreases.

colin_mcmillen,
@colin_mcmillen@piaille.fr avatar

@santiago Oh! no, not that way. I thought even lines on page 0 and odd lines on page 1.
Interlacing by refreshing only half the lines would be ugly - I tried that, deferring some pixels until next frame, and it doesn't look good.

I got the privilege of spending an evening pair-programming with qkumba and learnt quite a few cool things! (also my video handler completes in 27 cycles instead of 31 🤯)

I've spent the weekend finding a more efficient solution to stream videos to my and found one that gains me 1.5fps, here's some documentation about it. https://www.colino.net/wordpress/archives/2024/04/28/how-i-stream-audiovideo-through-an-apple-ii-serial-ports/

progress of the weekend :

  1. clean text subtitles

  1. basic playback controls

A video of the same scene, playing. I can now pause the stream and resume it using the space bar, and rewind/forward 10 seconds using left and right arrow keys. The video is shot in idiovision (vertically), so you may have to fullscreen it to view the keyboard.

Sister Voyager 1's confirmation of the memory space reallocation of Flight Data Subsystem encoding of engineering data at the EL-40 engineering low data rate (40 bps) should be arriving at Deep Space Station 43 over the next 4-1/2 hours. The code was relocated to avoid damaged memory addresses that can no longer be reliably used. The Voyager engineering team believes that certain addresses or even a whole chip has been damaged or simply failed, causing the communications problems that have caused problems since last November.

@NSFVoyager2 the fact these folks are binary-patching a live system at a few bps and with a lag of almost two days blows my mind.

Conseil

Je commence un nouveau taf et les 10 km sont trop long pour un vélo tradi (j'ai qu'un vélo hollandais, classe, mais plutôt orienté balade).

Je viens donc à la pêche de conseils d'achat auprès des -eurs.

L'usage sera essentiellement pour aller bosser.

Budget jusqu'à 2000€

1/ Quelle modèle / marque ?
2/ Y a-t-il un risque a acheter d'occasion ?
3/ quelle précaution a prendre contre les vols ? le système intégré ou il faut rajouter un dispositif ?

colin_mcmillen,
@colin_mcmillen@piaille.fr avatar

@Thierry31 rajoute un (ou deux) bons U. Perso j'en laisse un sur le vélo et un au travail.
L'idéal évidemment c'est d'avoir la possibilité de laisser le vélo dans le bureau, mais tout le monde n'a pas cette chance.

6 years ago out of curiosity I started to do a quick HDD benchmark on Atari STE with GFA Basic and it ended as a full port of Bad Apple. My first 68000 assembly code in 20+ years

@fenarinarsa This is so impressive. The stuff you can do at 8MHz 😍
You should try to make an arbitrary video player :)

@colin_mcmillen@piaille.fr avatar

@fenarinarsa I realize that having to prepare the file on a different computer is actually harder than streaming it real-time. You could drop frames if you want to avoid buffering on camera switches or other big frame-to-frame diff, but whereas I can do that easily (just by counting wall clock time and figuring the delta has taken more than 41667µs to transfer), while you, you would have to compute a lot of variables to figure out where the computer would not follow...

I feel kinda insulted that Youtube's ContentID algorithm didn't even flag any of the demo videos I uploaded.

But I'll take it!
