lime!

i use a Kobo Clara HD. It runs linux out of the box, the system memory is on a removable SD card inside the case, and the user account is defined in an SQLite database on disk. If you add an empty user account to the database, it removes the “create account” screen and disables any Kobo online services. Then you can install KOReader and upload files over USB as everyone else has said.

Depends on what your focus is. If you want to build understanding of electronic components and how they interact through experimentation, Paul Falstad’s circuit simulator is a great start.

If you want to focus on digital logic, Logisim is great.

But here’s the thing: A microcontroller is controlled only through code. You want to learn electronics, you can simulate those. You want to learn about a specific microcontroller, read the manual for that controller. You want to learn to code a particular language, you learn that language.

You want to code on a microcontroller, get a microcontroller.

The raspberry pi pico is $4.

Edit:

Okay, so i was clicking around on Falstad’s site as i haven’t been there for a while and i found a thing called AVR8JS

This is literally what you are looking for! It allows you to set up a circuit, and use a simulated microcontroller to run C code on the circuit!

this doesn’t match my experience at all.

i had the misfortune once of having to try to understand a >400kLoC python codebase in a critical position and let me tell you that maintainability is a Problem. the system was older than most of the best practices of today and had a structure i can only describe as “a duolith of sqlalchemy soup”.

it’s weird that. it’s obviously possible to have a flat-shaded skeuomorph, just look at basically all of windows 95, but for some reason we connect them to this particular graphical style. files and folders are both part of the old classic “desktop metaphor”, so they basically have to be skeuomorphs. but like, the application icons are basically just mosaic tiles of the normal icons.

a proper skeuomorph would indicate what the program is for. krita and whatever map software that is are both good, if a little flat. but the libreoffice suite just being squares with a letter on them? have them be like, a spreadsheet for calc, a stack of cards for impress, and a printed page for write.

remember all the icons for windows 95 network utilities that have people in them? those are also (attempts at) skeumorphs because they’re trying to communicate what the program does.

a skeuomorph (from greek, “tool/container-shape”) is something that retains the characteristics of another thing that it is based on, even though those characteristics are no longer useful. think lamps shaped like candles, or the floppy disk save icon, or media player programs with volume knobs.

skeuomorphic UX is a good way to get users comfortable with a system by using designs they are already familiar with, and the original iphone used this to great effect.

This is a good example of skeuomorphic UI:

all to say, I’m not entirely sure these icons are skeuomorphs. they’re just glossy.

it looks sort of like a continuation of the beaker browser project. basically, a peer to peer browser that also serves content you have made to others using the browser. it’s a cute idea.

i’m currently going through it! company is slowly collapsing around me and despite promises of transparency there is no official communication from the board. we get all our information from news articles and office gossip. people are quitting left and right and no acknowledgement of this is made from above. it’s a very odd situation.

yeah one thing we couldn’t fix before losing interest was eventual consistency and authority. files would sort of flicker in and out while state was being propagated. i dread to think what kind of bandwidth use that thing would have when sharing large files.

buildings with upward-facing spotlights, especially single-family homes with façade lights. it’s like nobody cares about light pollution.

it was nothing official, just a toy file sharing thing using the chord dht algorithm. it consisted of a single binary that you fed with a directory and the IP of an extant member, and it would sync everything on the network into that directory.

no edge cases handled, so the 90% remained.

sure, do that. and good luck with this, i did something similar for a project once and as usual its those last 5% that are going to cost you 90% of the time.

your reaction makes me more confident that this may turn into something interesting :)

i take it then that files must have some ownership information associated with them, to distinguish the author from a relay node? or is that just a private key.

i’m interested in the dynamic linking, what mechanism is used to stop situations like left-pad or the pypi incident where a file is removed replaced with a malicious alternative?

if I’m reading this right, it’s a bit like ipfs+dht. is this a content-addressable system?

anyway, you should probably have demos of

• large files (like a Linux disk image), to demonstrate consistency in transfer.
• Video stream, to demonstrate performance and low latency.
• multiple files shared with many peers at once, to demonstrate scalability
• sharing with low bandwidth and high latency, to demonstrate possible mobile use cases.

thoughts:

• the logo is very close to wireguard’s.
• if the data is stored on peers, that means there must always be people with free storage online for it to work? how much storage is needed? is that data in plaintext? could a bad actor push illegal content to peers without them knowing?

also, please convert the whitepaper to a format that is actually readable. rtf? really?

wait hang on, what? source on that?

i can see what it points to. you can’t claim the statement is unfalsifiable just because you didn’t see the issues before removal. like, this is not proof-of-god tier stuff.

it took you as long to find that link as it would have to look up the thing they gave you. this is not kindergarten, nobody owes you you their time. you are expected to be able to find and evaluate the validity of information yourself.
