I think Y.js 14 and the new y-prosemirror binding fix a lot of the encountered issues

There is a small series of posts on the BitSquid blog about memory allocation which is worth reading! http://bitsquid.blogspot.com/2015/08/allocation-adventures-3...
From the post:

> In conclusion, the off-center “x” is real and probably an artifact of the display or how it is rendered. It is unlikely that it is the result of chromatic aberration.

By reading some code here https://github.com/Timot05/logic-card/blob/main/elec/src/log...

I wonder if with directional arrows, instead of writing "out ~ switch.in; switch.out ~ power.gnd", we could write "out ~> switch ~> power.gnd" instead?

But without distinction between in and out ports it may not be possible to check if connections are valid ones.

Anyway, this project really makes me want to learn electronics! Congrats!

I've only worked with Akka Graph DSL to build some data pipelines or protocol stacks. And I've loved working with it!

The equivalent of atopile signal would be port with Akka I think. A combination of ports gives us a shape. A source shape is just one OUT port. A flow shape is one IN and one OUT port, etc.

I'm very new to electronics so I don't know if it makes sense, but connecting all these ports with directional arrows was really helpful to understand the data flow.

It reminds me of the Akka Graph DSL[1]

This is exactly the point. One more dependency, one more executable. Redpanda get rid of that.

There is also libhydrogen [1] which is a "small, easy-to-use, hard-to-misuse cryptographic library".

There is JEB Decompiler too: https://www.pnfsoftware.com
I've often noticed this pattern but only ask myself now, so, yes, in general. From what I remember I never learnt that in school, but I'm obviously not a native English writer. @Raphmedia already gave me a good link, but thank you for the one you gave me too.

This is really interesting! I've hoped of a scenegraph based web in the past, all rendered in a canvas (indexing can be done by serving a simplified html representation by checking the user agent). I think the most challenging part is text rendering, but some people have done some work in this area (https://github.com/astiopin/webgl_fonts). Also, we may need some sort of API to trigger keyboard showing on mobile device. Anyway, congratulations!
