2024-08-13 01:23:02 <xentrac     > akkartik has been doing some really interesting explorations in Mu
2024-08-13 01:23:08 <unjust      > i see you've mentioned CP/M a few times in that article, ever written any PL/M?
2024-08-13 01:23:23 <xentrac     > no, although my uncle recently decided to write a PL/M compiler
2024-08-13 01:23:52 <xentrac     > it won't be his first compiler so maybe he'll finish it
2024-08-13 01:23:56 <unjust      > +1 for your uncle
2024-08-13 01:24:13 <unjust      > i downloaded a bunch of PL/M docs recently
2024-08-13 01:24:20 <unjust      > it looks like an interesting language
2024-08-13 01:24:37 <unjust      > at least from the PL/M-86 perspective i was looking at
2024-08-13 01:24:56 <xentrac     > I feel like CP/M is pretty close to the minimum viable platform for pulling-yourself-up-by-the-bootstraps
2024-08-13 01:26:05 <unjust      > what is Mu?
2024-08-13 01:26:19 <xentrac     > akkartik's live Forth spreadsheet shell
2024-08-13 01:27:04 <xentrac     > with a PDP-8 or 8008 or 8051 or HP-9825 you probably really want a bigger computer to use for your actual development environment, but an 8080 or Z80 is powerful enough to host Turbo Pascal or fig-Forth
2024-08-13 01:29:18 <xentrac     > well, not exactly Forth: https://github.com/akkartik/mu
2024-08-13 01:30:50 <unjust      > i remember reading that there was even a Turbo Modula-2 for CP/M on Z80 at some point, and the author had suggested that it was probably a better product than Turbo Pascal but Borland had ditched it for some reason
2024-08-13 01:31:20 <xentrac     > yeah, I don't know anything about it

2024-08-13 01:39:36 <xentrac     > Mouse sounds like the dc programming language from Unix
2024-08-13 01:40:12 <xentrac     > yeah, almost exactly like it
2024-08-13 01:41:10 <xentrac     > I recently learned that Lorinda Cherry originally wrote bc entirely in lex and yacc, emitting dc code
2024-08-13 01:41:27 <xentrac     > although "entirely in lex and yacc" doesn't mean she didn't write any C
2024-08-13 01:41:39 <xentrac     > it just means the C was inside .l and .y files :)
2024-08-13 01:54:29 <xentrac     > I just uploaded an asciicast of the minimal viable Forth roguelike to https://asciinema.org/a/671875
2024-08-13 02:02:04 <unjust      > how do you record your terminal for that?
2024-08-13 02:02:35 <xentrac     > with asciinema rec, which uploads to the asciinema server if you don't specify a filename
2024-08-13 02:02:54 <xentrac     > if you do specify a filename you can asciinema upload it later
2024-08-13 02:02:59 <xentrac     > which is what I did
2024-08-13 02:03:24 <xentrac     > the server deletes anonymous asciicasts after 7 days, so I linked it to my account on there
2024-08-13 02:05:46 <xentrac     > because of the simpleminded redisplay logic this 95-second asciicast is 1.1 megs uncompressed, but the server flate-encodes it to 63 kilobytes
2024-08-13 02:07:32 <xentrac     > a nice feature of the asciinema website lacking in, for example, YouTube, is that you can copy and paste code from the screen :)
2024-08-13 02:07:56 <unjust      > that would be pretty useful
2024-08-13 02:08:43 <unjust      > i'd also like to be able to draw arbitrary rectangles for immediately screengrabing
2024-08-13 02:09:15 <unjust      > but i guess you could probably?/maybe? write some javascript to do something like that
2024-08-13 02:09:25 <xentrac     > it *is* useful!
2024-08-13 02:10:21 <unjust      > not sure if you can grab a canvas or some kind of raster as a still from a video element. any idea?
2024-08-13 02:10:30 <xentrac     > I'm sure there's a way... let's see what SO thinks
2024-08-13 02:11:04 <unjust      > i'm thinking about this in the context of grabbing images of interest out of youtube videos on the fly
2024-08-13 02:12:27 <xentrac     > yes, apparently you can use the HTML canvas 2D context .drawImage() method with an HTML <video> element as the source parameter: https://stackoverflow.com/questions/62290451/screenshot-from-html-video-element-to-small
2024-08-13 02:12:52 <xentrac     > and then you can canvas.toDataURL('image/png') as usual
2024-08-13 02:13:55 <xentrac     > here's another answer using the same technique: https://stackoverflow.com/questions/43007634/javascript-how-to-extract-frame-from-video
2024-08-13 02:14:30 <unjust      > thanks for digging that up
2024-08-13 02:15:00 <xentrac     > if you're playing the YouTube video in mpv, the 's' key saves a screenshot
2024-08-13 02:15:08 <xentrac     > sure
2024-08-13 02:15:17 <unjust      > i have a slowly growing collection of bookmarklets to overcome annoyances on popular sites, this might turn out to be a new one

2024-08-13 02:16:06 <xentrac     > yeah, I use yt-dlp and NewPipe to overcome YouTube generally
2024-08-13 02:22:45 <unjust      > so does that mean you're not subjected to the random recommendations youtube believes you need see?

2024-08-13 02:23:31 <xentrac     > NewPipe shows them, yt-dlp doesn't; I've often found them useful

2024-08-13 17:28:10 <xentrac     > hmm, now that I've colorized it the screencast is getting rejected by asciinema as too large.  I guess it doesn't gzip it before uploading, or doesn't use the gzipped size to make the rejection decision
2024-08-13 17:29:20 <xentrac     > it's 8.9 megs and even gzipped is 780K
2024-08-13 17:29:43 <xentrac     > so I guess I need to do some optimization

2024-08-13 23:31:13 <unjust      > xentrac: was it the abundance of x364 codes that caused asciinema rejection?
