QBot - The Moderator For Discord

Sat, 27 Oct 2018 13:11:24 +0000

Hi there again!

I've been working on a Discord bot, using the Discord.js library.
I have released it a few months ago, and did a recode a few weeks back.

QBot

So, where does it get that name from? Q, of course. My favourite letter.

And the description of the bot? "The Moderator For Discord", because it's speciality is of course moderating.

Well then, the core features of this bot.

~ AutoMod - Including NoSpam, NoSwear, and capitals detector.

~ Virtual Dashboard - QDashboard

~ Moderation and Administration features.

~ Lockdown/mute commands to prevent raiding.

~ General server commands, helpful for stuffs.

A full list of commands: https://QBot.qclient.nl/commands.html.

IRC bot standards

Mon, 20 Mar 2017 20:51:03 +0000

This is a brief thread to read if you're thinking of making an IRC bot.
To get started follow the rules laid out in https://forum.openredstone.org/rules.php -- specifically:

Bots:
- Bots should only speak to the user who would like for it to be spoken to. Be it either a command-based bot or an updater bot that notifies, it should receive the explicit consent of the recipient to receive the message.
- Bots should only speak in private messages so as to avoid clogging public communication.

Additionally -- and this part is just my opinion -- I think it's better to only respond to commands given in private messages to the bot, as people using commands can get quite spammy in pub chat.

Now the standards:

Help dialog:

ALWAYS include a help dialog which can be accessed by messaging the bot "help".
Make a forum post containing the help dialog, and make the bot's help command a link to that thread.
Give example commands in order for the bot's user to understand what each command does.

Ping command:

I strongly recommend a "ping" command as it's very useful to see if the bot is responding, and is pretty standard.

Keeping your box safe:

It's more important when running an IRC bot, for your box(computer) to remain safe while running it, than for the IRC bot to have cool commands, so here's a list of common security issues to avoid:
•Never ever ever use eval() or exec() within your code, if you want a "calc" command then use a library for the language you're writing the bot in that is designed for mathematical expression evaluation.
•Don't include any commands that could potentially damage your system, even if they're restricted to *only your use*, perfect security on IRC is nearly impossible, and you're bound to eff up somewhere.
•If you have a command that does any sort of web access make sure to sanitize the user input before passing it, and rate limit the command, you don't want someone able to make calls to a website from your box at will with no rate limit.
•When sanitizing user input to make it safe for a command NEVER use a blacklist, ALWAYS use a whitelist. With a blacklist you're bound to miss something somewhere and when you do someone will find it and down goes your box.
•Straight up though, just rate limit like, every command, it makes it so people can't stall your bot by spamming it.

If you have any other things you think I should add to this reply to this thread and I'll consider adding them.

Temp : Temporary variable, deletes self upon `get` : _
Const : Constant variable, deletes self after one day : !
Dyn : Dynamic variable, able to be deleted with `del` : ~
Pass : Password protected, only readable with unlock : ##

Variable names are restricted to 0-9a-zA-Z_~!*-

Example commands:
Setting a constant variable for pi:
set !pi 3.14159

Setting a temporary variable that will be deleted after someone `get`s it:
set _myPassword ∆

Setting a dynamic variable that can be deleted after a few people see it, and then deleting it:
set ~dynamic ThisIsASecret
del ~dynamic

Setting and getting a password protected variable and then deleting it:
set #password123#varNameOfPassProtVar This is the value within the passport var.
unlock #varNameOfPassProtVar password123
del #varNameOfPassProtVar

Setting a read/write variable that anyone can modify and can't be deleted:
set MyVar

Getting a variable's value:
get MyVar

A new plugin from me. :P Auto Crafters!

Thu, 16 Feb 2017 20:32:18 +0000

I made another bukkit plugin for public use......

https://www.spigotmc.org/resources/autocrafters.36406/

So I will code Bukkit plugins.

Tue, 14 Feb 2017 15:36:50 +0000

So I am willing to code bukkit plugins for people.. (Depending on the plugin I might not do it for free)

Mostly I am bored and want some stuff to do and still keep my coding skills up.

so yeah.

Starting A Cryptocurrency

Sun, 11 Sep 2016 00:10:47 +0000

Hi guys, Halflife390 here;

Bloody hell its been over a year since I have even been on the server! So many new people, well time moves on.

Im just so busy with IRL projects so have no idea when i'll be getting back to redstone, I do however check the forums sparsely when I have time.

Anyway for those who are interested, for the final project of my computing course we are instructed to make a program in visual basic. There is literally no requirements for it except it obviously has to be sophisticated so you can get loads of marks. Just to give you an idea, one guy I know is making firmware from scratch (using no library's) to control a 3D printer he is going to assemble himself.

I decided to go down the purely software root like most people and really wanted to make a complex program that isn't some kind of boring database and will be fun to make. I have decided to basically make my own cryptocurrency like bitcoin. I have analysed the bitcoin protocol and examined vb's capabilities and have deemed the project as feasible and possible within the given time frame. I already have some parts of it coded and working such as the p2p networking and sha256 hashing and mining function. If its not already clear, this is a project for getting a qualification so I'm not actually going to distribute it around the world and try to make money, its for fun. However, the program will be backed by the same cryptographic hashing technology that secures bitcoin so there is nothing stopping me from actually distributing it if I wanted to (there is no reason for anyone to use it though).

I have just started the project and its needs to be finished by January. I'm posting this here if anyone is interested and wants to know more or maybe even volunteer to be a beta tester?

If you have any questions or want to know more just ask!

I need a new name for nick_bot.

Linux tools ?

Wed, 24 Aug 2016 03:11:03 +0000

I am moving to Linux as my daily driver. I am hoping to move to chromixium. For those of you who don't know chromixium is the open source version of chrome os that is found on Chromebooks. I am familiar with Linux.

That being said I was wonder what are you're favorite Linux tools , GUI and or command line ?

some of mine are : python , nano, gedit , lynx ,wget , chrome, mplayer ,and tmux

Completely off-topics, you guys are my last hope

Is there any way to only give harddrive access to specific processes in Win7?
I am programming an automic capture tool to record HDTV losslessly. My harddrive is fast enough but as soon as it gets one additional I/O command from another process, the capture tool will have to drop frames because the disk cannot keep up.

Time based file compression idea?

Fri, 06 May 2016 01:36:02 +0000

I have this idea for saving bandwidth using a compression(?) idea I've been thinking about, but I really need to hammer out details before I continue. The idea is to use a timing mechanism to cut down the amount of bytes sent.

We start with a 3d box fill with cubes. The exact dimensions can be adjusted, but in this case the box is 65536x16x8. Each cube is a byte of data. The values inside the cube are determined by a pseudo random number generator, with a shared seed. This box will (or should in theory) be identical on both ends. Start with the number 0 at the exact beginning of the minute, and incrementing 1 for each millisecond after the beginning of that minute until you reach 65536, filling data along the way. This interval can be represented as a 16 bit number, 2 bytes.

So if the time is 12:34PM, 56 seconds, 789 milliseconds:
0 means 12:34PM, 56 seconds, 0 milliseconds
55 means 12:34PM, 56 seconds, 55 milliseconds
900 means 12:34PM, 55 seconds, 900 milliseconds

Using another 16 bits, 2 bytes, for selecting rows of 8 byte data, makes a total of 4 bytes of bandwidth used for 8 bytes (most likely scenario) to 128 bytes of the file.

In theory, if you have really bad luck, you could wait days, weeks, months, years before the file finishes downloading. I know this, but without tests, I don't know what the most likely scenario is.

Are there any (other) flaws with the design? I'd like to find out now rather than after i start working on it.

TL;DR download anything over the internet using 1 bit of bandwidth. Just start at 0 and count up. See you next millennium

Python + Bluetooth + Arduino = ;(

Fri, 08 Apr 2016 16:08:52 +0000

I'm trying to get python to connect to the HC-06 module on an arduino, so I can control the arduino from my laptop.

Unfortunately Stack Overflow doesn't have the answers, so does that make it impossible?

I Dare you to fix this
