Don’t End The Week With Nothing

Posted on by

This on HN today: Don’t End The Week With Nothing. It referenced Developer Evangelism: The Whole Story and Jason Cohen – Designing the perfect bootstrapped startup MicroConf 2013 (audio and transcript here). Jason Cohen’s formula is:

Predictable acquisition of recurring revenue with an annual pre-pay option with a product which solves a demonstrable, enduring pain point for a business.

PHP finally blocks not run on exit

Posted on by

I confirmed with the following code that if you call ‘exit’ withing a ‘try’ block the ‘finally’ block does *not* execute. That’s probably what you would expect. But now we know.

register_shutdown_function( 'handle_shutdown' );

try {

  exit;

}
catch ( Exception $ex ) {

  echo "caught...\n";

}
finally {

  echo "finally...\n";

}

function handle_shutdown() {

  echo "shutdown...\n";

}

KDEInit could not launch ‘/usr/bin/kcachegrind’

Posted on by

When I open *.xt files from Dolphin on my KDE Plasma desktop Dolphin would lock up while kcachegrind ran and then when I exited kcachegrind Dolphin would complain:

KDEInit could not launch '/usr/bin/kcachegrind'

So what I’ve done is to create a custom kcachegrind.sh script to run xcachegrind properly and then re-associated *.xt files (application/x-kcachegrind) with the new script in Dolphin.

Bug fixed!
