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

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.

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

Additional command "flash" allows to upload firmware to EEPROM. When the coordinates are precisely determined, when flashing the position of the microcontroller can be omitted - at the first start it will determine its position from neighboring sate

This is an object-oriented library, the main priority of which is the maximum possible performance. It works on the double buffering concept, it has a lot of widgets, animations and custom event handlers support. All programs from the screenshots above are implemented with its help. If you want to develop a fast and beautiful program in just a few lines of code without butthurt - then this library is made for you. Detailed illustrated documentation, installation methods and tons of practical examples are available at: https://github.com/IgorTimofeev/GUI

The sound card is added by Computronics, a wonderful addon for OpenComputers. There are a few who actually know what it does. Even less people are able to use it. No one dares to understand how it works, or so I hope. Anyway, it appeared a few years (?) ago, and is still mostly undocumented. There is a page in the in-game manual, which fails to explain how great the card is. Of course it does! It has a heap of different methods, which you can use to cast many crazy magics to make the sound card sound, and it's impossible to teach someone to do magic by reading a single page. OK, I'm

I present you a program for a robot that allows you to mine ore without going down into the caves. Robot, using a geolyzer, can find and mine ore. All features are not yet implemented, so I ask you to test and inform me about a bugs. Requirements: Computer case (tier II or III) Inventory Upgrade (more the better) Inventory Controller Upgrade Hard Disk Drive EEPROM with Lua BIOS Geolyzer RAM (tier I or higher) CPU (any) Hover Upgrade (tier I) Diamond pickaxe or equivalent tool Optional: Crafting

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

Of course there is. Assembling a drone with a leash upgrade produces a drone that can transport cows, horses, sheeps, and pigs. Like this: Or... like this: Besides, drones are entities. They move in straight lines; they don't get stuck in the fence and can actually enter a house through a door. They move pretty fast — about 6 blocks a second (robots are at least 2 times slower). Drone's movement is asynchronous, so the machine can execute some other code in the middle of the flight. Drones can fly above the block height limit. The screenshot above was made while enjoying th

This BIOS allows you to choose the boot device by either using the arrow keys or clicking/touching the monitor. When using the keyboard use Enter to boot, when using clicking/touching click an unselected entry to select it, click a selected entry to boot it. If there is only one bootable medium, that medium is autobooted. The default selected option is the last booted device. This supports booting from filesystems, using /init.lua as an entry point or from drives(HDDs or Floppys in unmanaged mode), by loading code from the first sector until the first \0 character appears a

OpenOS has absolutely proper pipes now, such as those you invoke with `cat file | grep foobar`, and a kick butt threading library (read https://ocdoc.cil.li/api:thread ) As for virtual components? No, there is nothing built into OpenOS for virtual components, but gamax92 has written a nice vcomponent library you can add via oppm, `oppm install vcomponent` Plan9k is retired, to be honest. It was ahead of its time, but is now outdated. OpenOS is faster, lower memory, has gobs of great libraries, super awesome command line parsing, and is ACTIVELY developed. I might be biased....

Please calm down. There are some component methods that block the computer for a tick when called, yes. Such methods usually interact with the world. For example, a transposer allows to transfer items between invetories by calling the transferItem method, which takes a tick to execute (so you get up to 20 stacks/second). On the other hand, there are a lot of direct methods, which can be called several times per tick. For example, the GPU's methods are direct. And the processor (as well as RAM) determines how many direct calls are allowed per tick. I think T2 T3 setup allows you to ca

Fuchas One of the best OSes (as said by me) Fuchas in a Nutshell Fuchas is revolutionnary in that it uses drivers instead of component access and support UAC (with separate permissions!) ! It's the end of the era where the program needs to maintain integration with different components, the OS now does it! The driver library will try automatically choosing the best driver, but it can be configured by user. Meaning programs adapt to components with no effort (e.g. Computronics cards) A feature of Fuchas is security. If you do not trust a program, you can control permissions. Each

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

Minitel Minitel is a simple, efficient networking protocol implementing layers 3, 4 and 5 of the OSI model. It supports automatic configuration and routing over large and small networks.

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

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

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..

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.

Zorya BIOS Zorya BIOS is an extendable and configurable BIOS and bootloader, capable of booting any OS with the right extensions. It's similar to GRUB. (sorry in advance for bios.lua) All you need to install the BIOS is to flash bios.lua to a blank EEPROM, insert a blank floppy, then reboot. Note: This has only been tested on Tier 3 hardware and Lua 5.3. requires an Internet card. Github repo PRs are welcome! Future plans: Ability to load from non-managed disks (like disks formatted with msdosfs, etc) Make it easier to extend Clean up code

While it is not possible to tell you exactly what to do instead, here are a few things you should've done a little bit differently to make this more pleasant and helpful for everyone: Your title: "make opencomputers processors faster". You are asking a question in your post which you want answered, why not make that the title instead: "How do I increase or remove the limits of the CPU/RAM?" This makes it easy at first glance for everyone to see what you try to accomplish "make [...] processors faster" sounds like you are giving someone the command to do so, which is n

This is a simple door opening script that requires a password to be entered. That being said it took me a ridiculously long time to work out all the bugs. It works by taking an input from one computer and sending it to another to check if the password is correct. This makes it much harder to simply look at the file to check what the password is. It also now has the ability to automatically encrypt your password if you have a T1 data card along with the server asking you to input a password on the first run. These ideas came from the user RandomRedMage Requirements: At least 2 compu

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

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

there was a regression caused by updates to JAVA that appears to have possibly broken OC in previous versions. Truth is we were likely misusing a nonblocking file handle, and we were vulnerable to this issue for a long time. But with recent java updates, this issue is causing this serious bug that you have encountered. We have patched our official release of OC to deal with this. You will need to do one of the follow 1. disable bufferChanges in the oc settings. you said you did this, this is actually how to protect yourself from the bug. I suspect you actually hit the bug when buffer

Yea, no problem. I'll also probably add the option to make the zorya-modules and zorya-config folders part of the normal filesystem. Might change how Zorya stores options to specify if it should download the modules or load them from the github repo. But I'll have to test that on my PC since OCEmu locks up when I try to fetch things from HTTPS

local fs = component.proxy(component.list("filesystem")()) local handle = fs.open("init.lua") local buffer = {} repeat local data = fs.read(handle, math.huge) table.insert(buffer, data) until not data fs.close(handle) local entire_contents_of_file = table.concat(buffer) stream handles naturally don't returns ALL of what you ask for, it can take multiple reads. read returns nil when the stream has ended (e.g. eof)

Also it might be a good idea download the file to /tmp instead of /, but that would require enough space in /tmp.

What should I do?

I just got this error! Am I doing something wrong?
