The Boring Game

I wrote a game! In 2.5 hours, even. It’s a console (as in Linux terminal) game, and written in Perl (5). I’ll call it “The Boring Game”.

You’re the pilot of a sophisticated airplane that does not crash into mountains, but bores tunnels through them. Flying costs money (because you use up fuel). Operating the boring machine attached to your airplane is extremely energy-intensive, and costs a fortune. Boring horizontally is expensive, but wait till you see how much you have to pay to bore up. However, (completed) tunnels are very useful infrastructure, so you get a nice reward every time you make it through the mountain.

The game’s settings are global constants at the top of the source file:

my $USLEEP = 80000;
my @STATE_CHANGE_PROBABILITY = (0.1, 0.4, 0.1);
my $MAX_ALTITUDE = 120; # (1 == one column). Need a few more columns to display the current funds
my $MOUNTAIN_CHAR = '.';
my $MOUNTAIN_OUTLINE_CHAR = '|';
my $PLAYER_CHAR = '@';
my $UP_CMD = 'k';
my $DOWN_CMD = 'j';
my $QUIT_CMD = 'q';

Here’s a YouTube video of the game in action:

To play the game, put boring_game.pl in any directory you want, and issue the following command:

perl boring_game.pl

KDE graphics problems (flickering windows)

On a Kaby Lake i7 (i7-7700) with embedded HD Graphics 630 on Debian Testing with KDE 5.28.0, I had a problem where the window manager (kwin_x11) would fail in the following way: everything would be fine for a few hours or a few days even, but then windows would flicker a bit, and usually much later window contents wouldn’t be updated until I focused a different window and then back, and after a while the whole screen froze and only the mouse pointer kept moving.

To fix a system that is still half responsive, open the run dialog (Alt+F2) and execute:

kwin --replace

To fix a system where no windows are updated, switch to the console and do:

DISPLAY=:0 kwin --replace

For a more permanent solution, selecting OpenGL 3.1 in System Settings > Display and Monitor > Compositor worked for me on one system.
