01:09 🔗 SketchCow Hi, back from dropping off friends.
01:09 🔗 SketchCow OK, so.
01:09 🔗 SketchCow I used the Pleasuredome CHD Torrent. It ABSOLUTELY splits things this way
01:09 🔗 SketchCow All I split was the directories with "What are the ones with one image" vs. "what are the ones with multiple imnages"
01:11 🔗 SketchCow So, we're now down to the J's with the PSX Uploads.
01:12 🔗 SketchCow I'm re-running the Metadata injector, which is the thing that puts in the data from the XML document of the Software List.
01:14 🔗 SketchCow It's at 820 items out of 2100 of the first easy batch.
01:15 🔗 SketchCow From 2010 Blog:
01:15 🔗 SketchCow Here are the default disk cache sizes for the major browsers:
01:15 🔗 SketchCow Internet Explorer: 8-50 MB.
01:15 🔗 SketchCow Firefox: 50 MB.
01:15 🔗 SketchCow Safari: everything I found said there isn't a max size setting (???)
01:15 🔗 SketchCow Chrome: < 80 MB (varies depending on available disk space)
01:15 🔗 SketchCow Opera: 20 MB.
01:16 🔗 SketchCow Ha, there's a tester for it.
01:17 🔗 SketchCow Yeah, looks like it's http://stevesouders.com/tests/cachesize/
01:24 🔗 SketchCow I have no useful response to the Cache situation other than we're forcing an example of the usage of it.
01:44 🔗 Vito` you can use indexeddb to store more, but it looks like only up to about 2gb per origin?
01:44 🔗 Vito` and the browser will ask if it's more than like 50mb
01:45 🔗 db48x it doesn't ask, as far as I know
01:46 🔗 DFJustin yeah I had to go in there and clean out some stuff because my ssd was getting full
01:46 🔗 bai this could be an interesting application for service workers
01:48 🔗 SketchCow Small update - I killed the "oops" item just because it's going to backfill into the regular thing.
01:48 🔗 SketchCow I wrote a simple script to cross-match our items into Mobygames links and I REALLY WISH I could hand it to someone but I don't think that's realistic.

02:02 🔗 SketchCow Not surprisingly, Mobygames is hitting issues with various Japanese games.
02:18 🔗 SketchCow https://archive.org/details/psx_alicecyb - This is what a "finished" entry will look like.
04:35 🔗 jvilk has joined #jsmess
04:35 🔗 jvilk What's going on guys?
04:36 🔗 jvilk SketchCow pinged me a few hours ago
04:44 🔗 DFJustin jvilk: did any work ever get done towards lazy access of large files in browserfs using http range requests
04:46 🔗 DFJustin we're trying to load playstation CD-ROMs in jsmess and it would be nice to not have to download 600mb all up front
04:55 🔗 jvilk DFJustin: oh nice! nothing has been done yet. there's something cooler we could do if sharedarraybuffers come back and we are able to put emulators into a worker.
04:56 🔗 jvilk It's something I'd like to return to once I finish my PhD (september!)
05:12 🔗 DFJustin ok
05:15 🔗 jvilk there's also the issue of memory usage, since Chrome limits tabs to 1.4GB. loading up 600MB fills up quite a bit of that.
05:15 🔗 SketchCow yeah
05:15 🔗 SketchCow we are pushing it
05:16 🔗 jvilk any chance of workerizing the emulators? or is that something that's still lots of work w/ emscripten?
05:16 🔗 jvilk (workerizing = running in a Worker)
05:52 🔗 bai jvilk: had some initial success with that when w rried a couple years ago, main problems were proxying audio and canvas data to main thread to actually draw. browsers now almost support OffscreenCanvas, but audio still needs to be proxied
05:53 🔗 bai also input needs to be proxied from the main thread
05:53 🔗 bai it worked but there was a little bit of extra latency
06:57 🔗 SketchCow Down to the R's.
06:57 🔗 SketchCow 1,466 done
06:57 🔗 SketchCow They're all just working.
06:58 🔗 SketchCow It's of course weird and there's some flakiness with emulation
06:58 🔗 SketchCow But a lot are just working.

07:29 🔗 SketchCow That's starting to have a nice look
07:29 🔗 bai nice
07:44 🔗 godane i always thought psx games was going be hard to emulate with java script cause of file size
07:46 🔗 godane i was thinking it was most likely to limit to less then 100mb games just say 'yes we can emulate psx' and nothing more

12:52 🔗 SketchCow My main thing was thinking if we couldn't emulate Jaguar, how could we emulate anything beyond.
12:52 🔗 SketchCow Apparently we can
12:55 🔗 SketchCow So, the first set is in, that's the ones that were obviously not multi-disc.
12:55 🔗 SketchCow 2,120 items!
13:21 🔗 SketchCow DFJustin: I found what you mean. Even though this thing is semi-official, i.e. someone is doing this using the MAME data, they lumped together similar titles in the case of "japanese version" or "demo" or "beta" version.
14:18 🔗 DFJustin "merged" sets based on the mame parent-clone relationships

19:29 🔗 SketchCow Whoooooooooooooooooooooooooooooooooooooooooooops
19:29 🔗 bai uh oh
19:30 🔗 bwn has quit IRC (Read error: Operation timed out)
19:40 🔗 SketchCow Well, it's not terminal.
19:40 🔗 SketchCow I'm getting most fixed pretty quickly.

22:21 🔗 jvilk I know I have been fairly inactive lately; I really want to come back in a big way once my schedule is less crazy. I would like to poke at things this summer, but that's also when I'm finishing my dissertation and moving. But this project has not been far from my mind; I would love to see big CD-ROM-based games come to life in the browser without super long wait time and the ability to easily download and up
22:22 🔗 jvilk load save files into the file system. Anyway, that's where I'm coming from, in case anyone was wondering.
22:22 🔗 jvilk All talk, no action this month. Of course, if there are any bugs/issues with BrowserFS, I'm responsive to those. :3
22:31 🔗 SketchCow That's OK
22:31 🔗 SketchCow The whole system is testing the limits of what browsers can do and I'm glad we're still on the forefront of that
22:31 🔗 SketchCow Also fuck Larry Ellison
22:31 🔗 SketchCow Also, I'm in London next week, I assume nobody here is from there.
22:39 🔗 SketchCow So, my splitter thing is working nicely. I'll be through it in the next few minutes.
23:11 🔗 oscar Ah, OK, I'm running into a strange thing... the Lua script stopped working and wouldn't start working, and I've found it's because when a new version is downloaded, it doesn't automatically truncate the file when overwriting it?
23:11 🔗 oscar So I have the new beginning of the file with a lot of trailing garbage, which is causing the file not to parse.
23:12 🔗 oscar I can have it manually delete/truncate the file before loading the new one, but I feel like I'm missing some flag value that's essential in cfgr.mountFile.
23:16 🔗 oscar Ah, I see. We have flag_w defined with isTruncating: false. Is that intentional?
23:18 🔗 oscar I feel like truncating the existing local data would be the expected action for fetching a file, but I'm not the one who wrote it, so it's good to check.
23:24 🔗 SketchCow When db48x is around he might know
23:24 🔗 SketchCow It must just be "default" and never hit an issue before.
23:25 🔗 oscar Right, that's what I want to check.
23:25 🔗 oscar But, as it turns out, changing it doesn't seem to fix the problem, hm.
23:25 🔗 oscar So, moot point.
23:55 🔗 oscar Hey jvilk: as long as you're here (if you're still here), is there an easy way to get to the ActionType global (or any other globals of BrowserFS) from the outside without calling BrowserFS.install()?
