in thread system call in crontab

If you want to change your X Windows background, feh will need to know the name of the X Windows display to use. It will expect that name to be in the DISPLAY environment variable. If you only have one display on your local system, its value will be ":0.0" so you could use this:
system("DISPLAY=:0.0 /usr/bin/feh --bg-center /home/user/Pictures/rota +te/1.jpg");
or better
$ENV{DISPLAY} = ":0.0"; system("/usr/bin/feh --bg-center /home/user/Pictures/rotate/1.jpg");

[marinersk]: choroba++
[choroba]: it's a long running test, so it's normally skipped unless an env var is set
[choroba]: nobody has been bothered to set the variable in the last 3 years
[marinersk]: sub newtest{my $expected_result = &target('foo'); my $actual_result = &target('foo'); if ($actual_result eq $expected_result) { &tdd_success(); } else { &tdd_fail(); } } # Test works after three years!
[choroba]: or nobody bothered...
[choroba]: The problem was bigger, as the test tried to call a method that didn't exist anymore
[marinersk]: :: ducking ::
[choroba]: because, someone renamed the method, but didn't notice it was used in the test, as the test was skipped
[marinersk]: Well, if the method doesn't exist, it would be hard to pass the test.
[choroba]: later, someone removed the new method, as all its usage places were safe, but didn't notice the test still used the old name
