15:10 < muurkha> yeah 15:10 < fenn> yeah he needs a "for nerds only" secondary channel 15:10 < muurkha> I think his target audience is 12-year-old boys 15:10 < muurkha> I'd be satisfied with a github repo 15:11 < muurkha> he does have a github account but only one repo: https://github.com/swighton 15:11 < nmz787> I actually used the excavator to help till the garden soil, it is definitely labor saving (and works in a pinch for things that really aren't the target application) 15:15 < nmz787> well, it saved labor after I got the tracks back on (BOTH popped off, presumably due to the slope I was moving across, and the track tension not being accounted for in the terrible chinese "manual") 15:15 < nmz787> I think I'm going to swap the rubber tracks for the steel set I have 15:16 < nmz787> I actually was just thinking of derigibles in place of cranes like a day or three ago 15:16 < nmz787> but I read getting into hot air balloons has like a $10k entry price 15:16 < nmz787> (getting into owning) 15:16 -!- mirage3359525 [~mirage335@64.79.52.86] has quit [Quit: Client closed] 15:17 -!- mirage3359525 [~mirage335@64.79.52.86] has joined #hplusroadmap 15:17 < nmz787> I just need a darn deuterium fusor to make hydrogen :D (or does that produce helium?) 15:17 < fenn> both 15:17 < muurkha> you can just make hydrogen from water tho 15:19 < nmz787> quit boring me 15:19 < nmz787> :D 15:20 * muurkha drills nmz787 instead 15:20 < nmz787> ablation only, please 15:21 < muurkha> hot 15:24 * nmz787 got the noVNC client (javascript and websockets) working in a web browser, using a socket:websocket proxy and served via a Python Flask app 15:25 < nmz787> I was not asked to do this, and I am not sure what problem I want to solve with this tool.... but now I have a neat tool in my toolbox, at least 15:26 < muurkha> nice 15:27 < muurkha> is there a way to hook up Xephyr (or Xnest?) to ffmpeg, the way Xpra sort of does? 15:27 < muurkha> it'd be neat if you could stream your app UI to a browser with H.264 15:28 < muurkha> I should say "sort of like Xpra" because I don't think Xpra actually uses either ffmpeg or Xephyr 15:28 < nmz787> no idea... I was trying to dig in to xpra but only scratched the surface 15:28 < nmz787> the author didn't seem to communicate the best 15:29 < nmz787> although they were responsive 15:29 < nmz787> I emailed the author of SAGEmath who customized xpra (at least the client side) for cocalc.org 15:29 < nmz787> and their reply was much more succint 15:33 < muurkha> I described the setup I was using in Derctuo; see file notes/virtual-machine-setup.html 15:33 < muurkha> or p. 209 in the PDF 15:36 -!- spaceangel [~spaceange@ip-78-102-216-202.net.upcbroadband.cz] has quit [Remote host closed the connection] 15:44 < nmz787> last week I was looking for javascript X11 servers, but failed to find anything that wasn't incomplete 15:44 < nmz787> the xplain github.io pages were cool though 15:45 < muurkha> you could probably use emscripten on Xnest or Xephyr 15:46 < nmz787> well I can't assume I can install anything on the remote ssh/vnc server 15:46 < nmz787> at least nothing major 15:46 < muurkha> do you know about emscripten? 15:46 < nmz787> that's the transpiler or whatever? 15:46 < nmz787> C to JS ? 15:46 < muurkha> yeah 15:46 < nmz787> or C to WASM 15:46 < muurkha> it does both now yeah 15:47 < nmz787> and then run a JS-based VM for WASM 15:47 < muurkha> that would be counterproductie 15:47 < muurkha> *v 15:47 < nmz787> pretty sure that is all I saw when I google wasm 15:47 < nmz787> basically you run some JS library that is a VM 15:47 < muurkha> the idea with wasm is that the browser supports, separately, both JS and wasm 15:48 < nmz787> hmm, maybe that is in the future 15:48 < muurkha> so it can run JS programs and also it can run wasm programs 15:48 < muurkha> all the major browsers have already deployed wasm support 15:48 < nmz787> since the whole UI isn't integrated with WASM, it seems like a waste of time for me right now 15:48 < nmz787> especially since, like I said, I'm not sure what problem I'm fixing with getting VNC in browser :P 15:48 < nmz787> I feel cool though 15:49 < muurkha> probably getting involved with wasm would cause you headaches to solve problems you don't have 15:49 < nmz787> yeah 15:49 < muurkha> I mean X servers ran adequately on 1-MIPS SUN workstations 15:49 < nmz787> I can imagine dependency-hell is another thing you'd need to deal with with emscripten conversions 15:50 < muurkha> maybe with JS you only get 500 MIPS instead of 5000 MIPS on a single core, but that's surely adequate 16:29 -!- deltab [~deltab@user/deltab] has quit [Ping timeout: 276 seconds] 16:37 -!- deltab [~deltab@user/deltab] has joined #hplusroadmap 18:44 -!- yashgaroth [~ffffffff@2601:5c4:c780:6aa0::93] has quit [Quit: Leaving] 19:20 < L29Ah> muurkha: so, is the cortexyme stuff any good? 22:05 -!- faceface [~faceface@user/faceface] has quit [Remote host closed the connection] 23:07 -!- mirage335952535 [~mirage335@64.79.52.86] has joined #hplusroadmap 23:11 -!- mirage3359525 [~mirage335@64.79.52.86] has quit [Ping timeout: 252 seconds] --- Log closed Thu Jun 09 00:00:47 2022
