Strange sequence of characters in terminal after each restart

After upgrading from Kubuntu 20.04 to 20.10 on my laptop, after each reboot, if I open the terminal, there is the following sequence written on the prompt:


Where could something like that be written, so I can correct it?

[AP] Minimum Characters for Post Count

This addon will stop users post counts from increasing, unless their message length exceeds a number which you can configure in the Admin panel (by default it’s 75).

This can be useful if you hire paid posters or do post exchanges, and don’t want people to cheese their way with low effort posts.

Array manipulation by deleting repeated characters in c++

I am trying to do some array manipulations where I need to delete all repeated letters from the array and it should return a new dynamic array where all repeated letters are deleted. I don’t want to modify the input array.

I came up with below code which works fine. Is there anything that can be improved in below code or writing it in a better way?

#include <iostream>
#include <cstring>

using namespace std;

char * delete(char arr(), int size) {
  if (size <= 0) {
    cout << "Invalid input passed." << endl;
    return 0;
  char * msg = new char(size)();
  int index = 0;
  for (int i = 0; i < size; i++) {
    int j;
    for (j = 0; j < i; j++) {
      if (arr(i) == arr(j)) {
    if (j == i) {
      msg(index++) = arr(i);

  return msg;

int main() {
  char array(200) = "hello world";
  int size = strlen(array);
  char * newArray;
  newArray = delete(array, size);
  cout << newArray << endl;
  delete() newArray;

  return 0;

Special characters directory issue

I have a cpanel server and when I use special characters in directories , I will not be able to access the files in that directory.

Here … | Read the rest of

How can I search for a keyword with special characters in Google Search?

Write it out:

-f: perldoc -f -X. If no file name is specified (as is the case here) checks if $_ contains the name of a plain file

>: Checks if the RHS is greater than the LHS

@+: In scalar context, returns the number of elements in @+

?: the conditional operator

*<: The glob for main::<

.: String concatenation operator

-&'_: Invokes a subroutine main::_. FYI, ' is the perl4 style package name separator. Try perl -MHTML'Template -e 1.

: : Continuing with conditional operator

$# : The output format for printed numbers

/ : Division operator

%! : %ERRNO; see perldoc perlvar

So, it is not impossible to understand if you put a little effort into it. Clearly, this is not how anyone should write programs, but there some benefit from people pushing the boundaries.

dnd 5e – How would you challenge a party of 8 players characters without killing them?

Large parties can be diffcult to run for any DM. You have a couple options to deal with this.

Force split the party

Pitfall traps, haunted houses with secret rotating doors, dopplegangers inflitrating the party, Magic maze, etc. By dividing the group, they can handle a lot less at once. This allows you to use creatures such as goblins, zombies and other lower CR monsters that a large party of even low level characters would normally step on as well as make sure each player gets to do something in a combat or have time to shine in a RP session.

Big monsters

As the party levels up, especially with 8 or more players, they will be able to take down higher CR monsters much quicker than a normal sized party of 4 or 5. Or you can send more creatures their way at one time. Orc war bands, gangs of Grimlocks, etc. Dropping characters is not the same as killing them, with 8 party mates someone is bound to be able to do some sort of healing. 5e is very forgiving with its death saves and low chances of insta death, keep in mind your players do have the option to run when things are tough, so don’t be afraid to gauge their strength and reward good teamwork.

Red flag

I have a party of 8 players and more continue to join (against my wishes).

This is concerning to me as you are the DM. Ultimately, you can only handle so much. I don’t know your situation but extra players joining eithout the consent of the DM is INCREDIBLY rude. You have to work hard to make sure everyone is having a good time. You have the right to cap off a campaign. If it gets too full then no one will have a good time. Perhaps these new people can play if and when you start a new campaign, or have another game going among themselves. To be blunt, if your game is full, say it’s full and be firm.

dnd 5e – What could a semi-malicious npc do with a player characters voice in a jar?

A merchant npc has been selling wares to my pc’s. In their most recent encounter, one of the pc’s was just a little short of the gold required to purchase a magical item he really wanted. Improvising, I had the merchant offer the pc a deal – all he had to do was say his own name into a little copper jar, and the merchant would discount the item enough for the player to purchase. The player, obviously, accepted.

For flavor, the pc found himself mute for a few seconds afterwards, and when questioned the merchant simply claimed he’d “taken a piece of his voice – not the whole thing, mind you, just a couple crumbs.”

While this encounter was colorful enough on its own, I was wondering if anyone had any ideas for how it could come back to bite the party in the rear. I was considering having the merchant use the voice to make a deal with (and trick) a demon, and then have the party encounter that angry demon later on, but I’m not 100% sold on the idea.

beginner – Count characters, words, and lines in files (wc in rust)

I wrote a barebones version of wc in rust. wc is a program that counts the number of characters, words, and lines in a file and outputs those values to the command line. Here is an example of the output:

   9   25  246 Cargo.toml
  52  163 1284 src/
  61  188 1530 total

My version currently lacks the proper output alignment, and it doesn’t print the total (it also lacks the command line options, and it panics when fed a directory). But I would like to get some feedback before I go any further.

use std::env;
use std::fs::read_to_string;

struct InputFile {
    words: u32,
    lines: u32,
    characters: u32,
    name: String,

impl InputFile {
    fn new(name: &String) -> Self {
        let content = read_to_string(name).unwrap();
        let (mut characters, mut words, mut lines) = (0, 0, 0);
        let mut spaced: bool = false;
        for c in content.chars() {
            if c as u8 != 0 {
                characters += 1;
            if c != ' ' && c != 'n' {
                spaced = false
            if c == 'n' {
                lines += 1;
                if !spaced {
                    words += 1;
                    spaced = true;
            if c == ' ' && !spaced {
                words += 1;
                spaced = true;
        Self { lines, words, characters, name: name.to_string() }

impl std::fmt::Display for InputFile {
    fn fmt(&self, f: &mut std::fmt::Formatter) -> std::fmt::Result {
        write!(f, "{} {} {} {}",
            self.lines, self.words, self.characters,

fn main() {
    let files: Vec<String> = env::args().collect();
    for f in &files(1..) {
        println!("{}", InputFile::new(f));

dnd 5e – Do Player Characters in 5e with a powerful build deal more melee damage like a monster would?

I have a player in one of the games I’m running that’s a Goliath Paladin. He uses a greataxe and recently asked me if he could deal more damage like a “Large” monster could since he has a powerful build.

According to the DMG, On p.278 it says:

Big monsters typically wield oversized weapons that deal extra dice of damage on a hit. Double the weapon dice if the creature is Large, triple the weapon dice if the creature is Huge, quadruple the weapon dice if it’s Gargantuan…

So since he counts as one size larger than medium, I thought that this rule could apply to him, HOWEVER, according to the powerful build mechanic, it states;

You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.

(Technically nothing more or less.)

My players are usually good, and don’t try to “break the game,” but before I make a decision, I would like to know what a community of other players and GMs would think about this. Would he be able to deal extra damage? Would it “Break the Game?”

Do Player characters know they are under the effect of a Death Tyrant’s Negative Energy Cone?

My players will be going up against a Death Tyrant very soon. The Negative Energy Cone states it is an invisible cone. Does this mean player characters won’t know they are affected by it?
