Capture and Report JavaScript Errors with window.onerror

“Capture and Report JavaScript Errors with window.onerror” tutorial shows an easy way to capture, log and troubleshoot client-side errors:

onerror is a special browser event that fires whenever an uncaught JavaScript errorhas been thrown. It’s one of the easiest ways to log client-side errors and report them to your servers. It’s also one of the major mechanisms by which Sentry’s client JavaScript integration (raven-js) works.

window.onerror = function(msg, url, lineNo, columnNo, error) {
  // ... handle error ...
  return false;
}

Reboot and wait for reboot to complete in Ansible playbook

Jeff Geerling shares a handy tip on how to implement the configure-reboot-configure pattern in an Ansible playbook.

---
- name: Do something that requires a reboot when it results in a change.
  ...
  register: task_result

- name: Reboot immediately if there was a change.
  shell: "sleep 5 && reboot"
  async: 1
  poll: 0
  when: task_result is changed

- name: Wait for the reboot to complete if there was a change.
  wait_for_connection:
    connect_timeout: 20
    sleep: 5
    delay: 5
    timeout: 300
  when: task_result is changed

Weird operators in PHP

“Weird operators in PHP” covers a variety of awkward and weird operators in PHP.  I don’t think I’ll ever write any code using any of these.  But in case I come across any code in the future, that utilizes them, I should be sure to search back in the archives of this blog.  Here’s an example to get you started:

In case you want to add some firepower to the previous fleet, you can summon X-fighters to the PHP source : +-0-+. The following code adds 3 to $a.

$a = $a +-0-+ 3;
