C# time.sleep not working as expected for no apparent reason

I hope this helps you . Thread.Sleep() blocks the UI thread, so you don't see the changes. You could use
code :
await Task.Delay(1000);

Time Delay using Thread.sleep() for paintComponent(Graphics g) not working as expected

I think the issue was by ths following , Don't block the EDT (Event Dispatch Thread) - the GUI will 'freeze' when that happens. Instead of calling Thread.sleep(n) implement a Swing Timer for repeated tasks. See Concurrency in Swing for more details. Also be sure to check the progress bar tutorial linked by @Brian. It contains working examples.
code :
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

class DrawPanel extends JPanel
{
    int i = 0;
    public DrawPanel() {
        ActionListener animate = new ActionListener() {
            public void actionPerformed(ActionEvent ae) {
                repaint();
            }
        };
        Timer timer = new Timer(50,animate);
        timer.start();
    }
    public void paintComponent(Graphics g)
    {
        super.paintComponent(g);
        g.setColor(new Color(71,12,3));
        g.fillRect(35,30,410,90);

        Color c = new Color (12*i/2,8*i/2,2*i/2);
        g.setColor(c);
        g.fillRect( 30+10*i,35,20,80);

        i+=2;
        if (i>40) i = 0;
    }
}

class ProgressBar
{
    public static void main (String []args)
    {
        DrawPanel panel = new DrawPanel();
        JFrame app = new JFrame();
        app.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
        app.add(panel);
        app.setSize(500,200);
        app.setVisible(true);
    }
}

File included in .gitignore gets deleted from time to time with no apparent reason

Any of those help Based on your description, it looks like the file was included in some branches before including the row in the .gitignore If the archive was committed before adding the exception, it will be there until you remove it explicitly. Review (and delete) the file from your repository to avoid this problem in the future.

time.sleep not working as expected when adding end= to print()

I wish this help you Happy to see that an OP can provide an executable example! The problem is simple, stdout has a cache, you need to flush the result:
code :
import time, threading

msg = "68 111 110 117 116 115 32 97 114 101 32 98 111 109 98 "
msg = [int(x) for x in msg.split()]

def print_msg():
    for c in msg:
        print(chr(c), end="", flush=True)
        time.sleep(0.2)

threading.Thread(target=print_msg).start()

CF push stopped working for no apparent reason

like below fixes the issue This line stood out to me npm ERR! Error extracting /home/vcap/.npm/fs/0.0.0/package.tgz archive: ENOENT: no such file or directory, open '/home/vcap/.npm/fs/0.0.0/package.tgz'
The fs module is one of nodes core modules and does not need to be installed. I think by trying to install it you are getting some problems.
