Reading time as lines-of-code per hour

I was wondering how many lines of code it was possible to read per hour. I found on the Wikipedia code review article the claim: “Code review rates should be between 200 and 400 lines of code per hour.” They say any faster is too fast to find errors. I also found on the Wikipedia article source lines of code that a contemporary Linux kernel has 20 million lines-of-code. So if you didn’t sleep and read code 24×7 you could read the Linux kernel in a little over 5 years…

Don’t End The Week With Nothing

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

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’

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!
