Due to quarantine, I got a bunch of time in my hands, I remember that since I first used this mod, back in MC 1.7 we had this phrase on Geolyzer description "It is theoretically possible to eliminate this noise by scanning repeatedly and finding an average. (Unconfirmed, needs further testing.)" Now, many years later, i do know quite some about statistics and got plenty of time So, lets begin We begin our dive in Statistics with an hypothesis, Does this number measured relate to an ore or stone, putting it in hardness terms, does the true number of hardness equal to

The world as I knew it had a problem. A plenty of bootloaders had already existed, and they'd all shared the same flaw: it wasn't me who made them. I've decided to put an end to that. Cyan is a multi-bootloader and a replacement for the plain Lua BIOS. The features it encompasses include: a whitelist to prevent random strangers from tampering with the computer a Lua interpreter to test your sudden ideas support for hot-plugging filesystems if you've forgot to insert a floppy the ability to format or label a filesystem, while we're at it loading the boot

FlatDB is an implementation of SQL (or SQL-like) commands for manipulating databases on the hard drive itself. This post covers: Available commands and overview. How to use the API. Limitations. Performance. Future plans. 1. Available commands and overview. The following commands are available within the API: SELECT DELETE UPDATE INSERT WHERE AND OR Tables are human-readable and a single-row table will typically look like this: #$ID|param1|param2 1|value1|value2 Tables are created as files, with t

There is an interesting device in the OpenComputers mod that allows you to determine the block hardness at a distance. But the trouble is, the data it gives out is rather noisy and the greater the distance, the more noise. To determine the true hardness of a block, we can scan it several times and average the result. The noise that interferes with scanning is of a probabilistic nature. And after several scans, you can statistically find what the most likely hardness of the block is. In one tick, we can scan 64 blocks. To analyze the entire available area (65 x 65 x 64) with hundred of

Last demo video: No, it does not currently run modded minecraft (albeit it runs plugins made for this server), but one experiment i want to do for later is recreating a bit of OC mod in Lua, to make it run in this server, so that you can run Minecraft server in Minecraft server in Minecraft server in Minecraft server in ... until it crashes your PC lol.

Anything not impossible is possible, and this feature doesn't even require much perseverance to implement. Right now we're using owner to store the nickname of one player. We are going to replace it with a table, and therefore the name owner is no longer satisfactory. Let's rename it as trustedPeople and populate it with some test names. local trustedPeople = {"player1", "player2", "player3"} A table is the universal record type in Lua, that is, the type that stores multiple values. But we still need to choose the correct data structure. The table trustedPeople is a sequence. This

I am sorry, but unless I'm misreading your code, it can't possibly throw an "attempt to index a nil value" error, with any people in proximity or without. And the question is contradictory, stating both that the program crashes and that it freezes (the latter is correct, however). Actually, I'm unsure what the actual question is. Therefore, I'll do the only thing I can here: that is, explain what your code does wrong and how to fix it. Before I can proceed to fix the actual issues in the program's logic, I have to get rid of some minor problems. The first such problem is that the code is

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

A while ago i made a JVM in Lua with the first goal of running Java on OC, just because i like Java and we all know it's a good programming language. So here's the JVM running a program that fills GPU: Oops, made a typo. Ok at first this might not seem impressive at all, but now you can interact with components using Java! That's an awesome thing for Java-ers like me! Race to first Java OS in OC? Anyone? Here's the (simple) code i used above import lukyt.oc.Component; public class ComponentTest { public static void main(String[] args) { String gpu =

How to Write an OpenComputers Operating System This is the kind of guide I wish I had had 9 months ago when I started developing operating systems for OpenComputers. It will walk you through writing a very basic OpenComputers operating system. EDIT: The guide I followed (the only one I found) is here: WARNINGS: -- This post assumes basic knowledge of programming, such as: what a string is, what a table or list is, what a function is, what a variable is, etc. I am NOT attempting to teach you Lua-- see warning #3 -- This operating system is not intended to have many featur

MineOS is half the operating system and half the graphical environment for OpenOS, which comes in OpenComputers mod by default. Oringinally it was developed in Russian, but it supports several languages. MineOS has following features: Multitasking Windowed interface with double buffered graphics context Animations, wallpapers, screensavers and color schemes Language packs and software localization User authorization by password and biometrics Support for file sharing over the local network via modems Support for client connection to real FTP servers

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.

Fuchas Fuchas in a Nutshell Fuchas uses drivers instdead of component access and support UAC (with new OS separate permissions!) ! Programs don't need 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) Notice about security: Fuchas is currently alpha and "security" (if we can even call that security) isn't done at all, however the UAC is functional. Fuchas also has a permission

First post here, hi. For the past few months, I’ve been working on an operating system for OpenComputers. It’s a monolithic, UNIX-like operating system. Note that Monolith will not currently work in OCEmu due to the lack of support for`computer.getDeviceInfo`. First, the advantages over OpenOS: - Monolith supports dynamically adding and removing screens, GPUs, and keyboards - it’ll automatically spawn a shell on an available combo and will try to match by tier. - Monolith’s userspace is properly sandboxed - there’s no way to completely crash the kernel from userland

There's software for importing/exporting components included with the Minitel RPC library (on oppm as mtrpc) tl;dr oppm install mtrpc exportcomponent <component address> [component address...] importcomponent <host> <component type> <component address> Doesn't work properly with components that return functions, like the internet card, but it works nicely with stuff like redstone cards and storage devices.

Not a Minecraft server about OC, but a Minecraft server running on OC. More specifically an 1.15.2 Minecraft server. (btw sorry for low video quality, but 2 Minecraft instances with one modded is CPU-intensive, so..) Installing Just look at the github: https://github.com/zenith391/OCMCS

Wait what? How? You did what? But can it run modded minecraft? How deep is the rabbit hole?

There is some issue with the tier 1 card. I usually use tier 2 anyways, therefore I didn't notice. Tried with a tier 1 card and I was able to replicate your findings. So for now, I would simply use a tier 2 card in the robot and computer and everything will work just fine without a relay. I'll probably have a look in the tier 1 card's source code later and file a bug report on github (unless you want to do that)

Hey If done correctly, you don’t need the relay. Communication between multiple computers/drones etc works just fine without. The way your setup behaves is somewhat strange, I can try to replicate this later. Anyways, do you have a wireless network card in both the computer and the robot? (I assume by drone you mean the machine called EDI in your screenshot, right) Also, the code you showed looks somewhat fine I guess, but it would be helpful if you could post both as full program, preferably not as screenshot but as snippets.

Just add this to your code: local shell = require "shell" local args, ops = shell.parse(...) You can read more on the shell.parse function here. But basically, options following a single '-' is split into single characters (that means -test sets the options t, e, s, t and NOT a single option called "test). To have an option name with more characters, use the double '--' following the name (--test will set a single option called "test") So, if you have a file test.lua, you could add the following (of cause also adding the 2 lines above as well) if args.o then -- do some s

have a look into the /bin/echo.lua, maybe something like this ?

The inconsistency comes from you pulling events twice and storing them to separate variables. That can mess up the different senders in your network. So what you need to do is pull an event once, check the sender's address and then perform some tasks based on the addresses. local event = require "event" while true do local _, _, addr, port, _, message = event.pull("modem_message") if addr == "one address" then -- # do some stuff elseif addr == "the other address" then -- # do some other stuff -- # you can add as many addresses in elseif statements as you want end

I don't know securitycraft or opensecurity but you can put a redstone card into the computer and get a redstone signal on incoming wormholes.

Okay thanks for the reports. I reverted the last update so it should be back to normal.

I am no longer running this server

Seems like this small script is gone, removed by codepen robots, and i cant find it in my archives. This script was cutted version of .vox converter. You can use it instead, but will need extra work on output. Your comment is my award! Thank you for using it and telling me this.

local function list_files(dir) local files = {} for path, err in filesystem.list(dir) do assert(path, err) if not filesystem.isDirectory(path) then table.insert(files, path) end end return files end -- # use local files = list_files '/home' -- # example result -- { -- 'test.lua', -- 'poop.cfg' -- }

Thank you. Honestly, neither did I. Until I decided to make a Point of Sale system and realized that I needed a database. If I'm gonna do it once, I might as well make a library.

That is mighty easy. computer.pullSignal = nil

I've modified this to be able to remove either a specific filesystem or the last added filesystem by either passing an address or '.' (for the last added) as the first parameter to the remove command. The second parameter is the forcefully option. so 'rc bundle remove ad432df3 true' (yes, short addresses are allowed).

I had this problem quite a long time ago, and I think I fixed it by also updating the settings client-side to match those on the server.

There is a new Stargate mod AUNIS that is looking very good,. and has added in Open Computers support. I was wondering if there would be a way to port this program to work with the new mod?

A while back, I've quietly released an unofficial, experimental OpenComputers fork called OC-Staging, available here. The key features as of writing include: Optimized GPU rendering code, providing up to 2x better performance (in terms of frame rendering time), LuaJ and JNLua bugfixes and updates, Native Lua performance improvements, Lua 5.4 support! (currently on lua-5.4.0-beta) This is the feedback thread for this fork, as input is sought before merging the changes back into OpenComputers due to their potentially invasive nature (for bug reports, please use th

ocCraft is a little videogame originated trough a very little OpenComputers game jam. It is currently not much more as the engine but should be easy to modify as long as you have a little practice with lua. Modding You can install/create your own texture packs (also with different resolution) as well as mods with new blocks, entities and biomes (world gen)*. *(technically you can change nearly anything at runtime because the most data are stored in a local table named global which will given to any script at loading.)

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.

ProjectOC has moved on! POC2 has got a reboot and is no longer active. The only reason this thread is still here is for historical reasons.

Not really. Lua uses 64-bit signed integers as long as possible (unless you force floating-point numbers by writing 4265.0 instead of 4265) and switches to double-precision floats for anything outside of that range. And if you exceed that range, then you get float infinity. If you're doing cryptography, you might want to look at the Data Card though. If I remember correctly the higher tiers provide some cryptographic functions too.

Thank you. Now it looks like something a ten year old can do. (Not joking nor being Sarcastic) But it should be easily done with something like 1. Make special X Block and put EEPROM Into it 2. Enter something like "edit (EEPROM Add)" 3. Enter code then remove EEPROM With Arduino the coding is "simple" much like OpenComputers.
