What is STEM? Did you ever want to have a linked card, but without this pair-to-pair limitations? Well, you have internet card. And that is already half of the solution. The other half is to use Stem. Stem is a message transmitter for your OpenComputers devices with internet cards. Using a small OpenOS library you can use Stem to send and receive messages. Unlike the standard `modem` component, Stem-messaging uses not addresses, but `channels`. You can send messages to any channels, and you can subscribe to any number of channels to listen for messages from them.

No spoiler in the title. Just watch the video. EDIT: Apparently someone's ComputerCraft fork is more findable on Google than the original OpenComputers repository, so here's the official source code: https://github.com/asiekierka/lunatic86

This is a working clone of Super Mario Bros. (with some missing features ). It was made thanks to the VRAM buffers feature (only available in experimental builds), the game runs quite smoothly and uses the Computronics Sound Card to play music on the same computer. It loads sprites from .bmp files, levels from Tiled (a free level editor) .json file and music is in some custom format that can be converted from MIDI files. This makes the game quite easily moddable. Source code

Ever needed real-world time in OpenComputers? I did today, so I did something about it. realtime realtime is a set of libraries and protocols designed to let you synchronise your computers with the real world, and includes: The realtime library, for taking and keeping time. The realtime-sync daemon, for synchronising your realtime library with the real world The realtime-relay daemon, for synchronising your realtime across the local network. All of these can be downloaded via oppm, or from the Minitel GitHub repository. Additionally, all of these come w

What's Netcoin? NetCoin is a cryptocurrency designed for OpenComputers, a Minecraft mod that adds computers in the game. It follows Bitcoin's original philosophy: a completely decentralized network of nodes, each one maintaining a ledger with everyone's transactions, grouped into blocks that miners need to create solving the proof-of-work (PoW). What's the crypto behind it? It uses Elliptic Curve Digital Signature Algorithm (ECDSA) to sign transactions and SHA-256 as a PoW. Cryptographic functions are not implemented by software, but OpenComputers provides a component (Data Card) that provide

Hey! I'm asie, and while I'm not an official certified OpenComputers developer, I contribute to the project from time to time. However, for a long time, I've had some types of patches in the pipeline that couldn't quite reach the upstream - fixes and changes like: a screen renderer rewrite, with major performance boosts; updates to JNLua and LuaJ, fixing bugs and significantly improving performance; Lua 5.4.0 support. For the purpose of testing these changes as a way to see if they are ready for mass adoption, I've created a fork of OpenComputers called OC-Staging. It

BIG UPDATE! I've worked out some updates and a new visual editor for the gui system. To use the gui just download http://pastebin.com/Dfgc6z0T to a computer as /lib/gui.lua and try your best. If you don't want to fight with the placing of elements on the screen, then you want to use the visual editor. It's alpha state, but i hope it will make no errors. The editor will create a full lua code as frame work for your own program in resolution 80x25 like for a tier 2 screen. But you need a tier 3 screen to use the editor it self. The program you can run then on a ti

Hi all! I mentioned this in IRC but realized I should probably post it here as well. I made a new architecture that runs WebAssembly. It’s available here on CurseForge.

uncpio is a rather simple binary CPIO extractor (File begins with 0x71C7 or 0xC771, made with cpio -oHbin). To acquire uncpio, run pastebin get YbrVjRwa /bin/uncpio.lua To use, make the directory you'll be extracting your CPIO archive to, cd into it, then run uncpio path/to/your/file.cpio And it will extract to the current directory. Currently only works in OpenOS, as far as I know.

KestrelOS GUI-based, Windows-alike, highly customizable, and safe Operating System for common pourposes What's the major GUI-based OS currently available? The amazing system created by Igor, called MineOS (I'm sure everyone by now knows about it). Igor's system is based on OpenOS, that looks like MacOS and is by itself the most amazing system released yet, with all sorts of programs and even 3D libraries which is mind blowing. So why create yet another GUI-based system? There are several reasons why I decided to take on this journey. First of all, the m

I got a plan on what I do! I'm beginning work on the 4.0.0 update! Technically it's not a complete rewrite, but I do want to completely rewrite it in the future, so I don't care. It's big enough I feel it deserves the number Please note I do plan on making a video on this thing to explain the update, so if you don't understand much of this it might make more sense. Here is a shameless plug https://www.youtube.com/channel/UCC492g_YuYcWKRIeQD3kqdQ The main thing with this update is the modules system: I have a website I'm making!!! Here are some screenshots of the INCREDIBLY BETA

I just finished the first version of bundle - a rc application which virtually merges multiple filesystems into a bigger one. You can use it whenever a RAID full of tier 3 HDD isn't enough for your needs. On the picture above, for example, you can see 10 RAIDs with 30 tier 3 HDDs which yield a virtual HDD that can store over 200MB of data. You can also use filesystems of different size and create files bigger than any of the used filesystems since bundle is capable of storing a file on multiple HDDs. If you encounter any bug, please report it on my github repository. Also check out the wi

I decided to make an editor with syntax highlighting, just for the fun of it. The name stands for "syntax highlighting editor", it's very unoriginal, but I'm bad at names To use it, run this command on OpenOS: pastebin get ZnwyunqL /bin/shedit.lua The color scheme was (sorta, I redid it later) copied from this paste. Features: Syntax highlighting! Indent on enter Line numbers Jump to line Hex colors are highlighted with the color they refer to (example: ) And probably more in the future if I need them..

PlotOS What started as a small test, is now a big project! How it all started It all started by me being bored in 2019, and trying to make a small OS. I had been always amazed by MineOS, Fuchas, and all the other great OSes out there! At first, I have tried making something that can just boot. After half a hour, it booted! But, it didn't do anything, it just waited for events, and displayed them. Then, I decided that it wasn't enough for me! So, I started making an actual shell. I have decided to copy as little as possible from OpenOS, and make my own of almost everything! After

Thanks for the effort @BrisingrAerowing . I've just integrated your changes with minor changes and bugfixes on my part into the repo and updated the pastebin file. In order to distinguish it from the old version, I also moved Bundle to version v1.1.

You can use the port that is not 80. since i said "SHOULD" and not "MUST". But i'll try to change this for better clarity

In OpenComputers we currently have a simple highly abstracted networking model. We do have ports, thankfully, but besides that the model is highly abstracted and thusly underpowered. The first suggestion, is remove the abstraction on network communication in the first place. Allow this to be configured in the mod preferences file, but have it enabled by default. By default, there is no “hardware addresses”. A cable is just that, a cable. The only API by the mod is “broadcast and receive”. In the OS provided by the game by default could still have the same API as now. The different is it’d

It is possible this was implemented elsewhere and I failed to notice it, but I did this as an exercise as exploring OpenComputers. My son and I play The 1.7.10 Pack for our sandbox fun (in survival mode though), and I wanted to see if I could easily use OpenComputers to replace the typical-and-complex nest of level emitters and crafting cards to maintain minimum amounts of certain items in the AE2 ME network. This is not terribly sophisticated, and is just "fire-and-forget" with respects to requesting the crafting operations from the ME Network. As I continue to dabble I may add in chec

Concepts Application: Executable code booting using OEFI in the EFI1 or EFI2 format. Conventional Booting: OpenComputers default booting method. Often called "BIOS" Opera

Well, first of all, if you only need the message to contain one string, then you are better off by just sending the string as the message, so no need to make a table with that string, serialize the table transforming it into a string which is then send via the modem, once received, transformed back into a table which is then indexed to get the string you want to send... But anyways, I would assume the error with the serialization comes from trying to serialize a nil value. You're using a timeout with your event.pull, that means, event.pull returns nil if no modem_message was received with

Update: Minor bugfix that fixes a crash between the holoscreens and RailCraft - OpenScreens v1.0.1

Hey, in these if statements, you need to use relational operators. Since you want to see if you're variable is equal to a certain string, you need the '==' (two equal signs). So you're code would look like this -- local require commands start local component= require (“component”) local sides = require(“sides”) local rs = component.redstone local event = require(“event”) -- local os = require(“os”) remove this, the os lib does not need to be required, I think -- local require commands end -- Main function start local function main() local username, message = event.pul

Thanks, that fits with the results I get with my testing! Here's a color table reference that I kinda... over-did (as is my way); it's indexed and includes the 240 main colors plus the 16 greys. Definitely a good resource for anyone who wants to plan color schemes in an image editor before coding them in (feel free to add it to the wiki or wherever, if you like; I happily cede it to you in delayed payment for adding remote component access to the debug card): Yes, if you change the color palette, anything you've drawn in that color will change to the new color.
