Remove a single Certbot (LetsEncrypt) certificate from a server

I've been using Certbot to generate and renew Let's Encrypt certificates for most of my smaller sites and services, and recently I needed to move a site from one server to another. It was easy enough to build the new server, then generate the certificate on the new server and use it in Apache or Nginx's configuration.

However, on the old server I no longer wanted to have the old certificate get renewed every week/month/etc. during the certbot-auto cron runs, so I looked to see if there was a way to simply have Certbot delete a certificate. It turns out there's not, but there is an issue—adding -delete option to remove the cert files—to add this functionality.

Increase the Guzzle HTTP Client request timeout in Drupal 8

During some migration operations on a Drupal 8 site, I needed to make an HTTP request that took > 30 seconds to return all the data... and when I ran the migration, I'd end up with exceptions like:

Migration failed with source plugin exception: Error message: cURL error 28: Operation timed out after 29992 milliseconds with 2031262 out of 2262702 bytes received (see http://curl.haxx.se/libcurl/c/libcurl-errors.html).

The solution, it turns out, is pretty simple! Drupal's \Drupal\Core\Http\ClientFactory is the default way that plugins like Migrate's HTTP fetching plugin get a Guzzle client to make HTTP requests (though you could swap things out if you want via services.yml), and in the code for that factory, there's a line after the defaults (where the 'timeout' => 30 is defined) like:

Mobius Mini Action Cam Pro - Dashcam setup and review

tl;dr: Watch the example/demo video below to see how the Mobius performs in a variety of driving conditions:

For the past few years, I've seen countless 'fail' videos, linked videos on reddit, etc. which show both the utility and entertainment value that comes from a dashcam—a camera that records everything that happens in front of your car while you're driving.

When looking around at the options for dashcams, and knowing my preference for reliability and ease of use, I came up with the following criteria:

Converting a batch of Dashcam videos into a timelapse

I recently took a family vacation from St. Louis, MO to Branson, MO, and as it was the first time driving with my new Mobius Action Cam Mini dashcam installed on our Toyota Sienna (see a full writeup and review here), I wanted to see if I could quickly whip up a time lapse video of the entire drive.

Should I disable PHP warnings and notices?

This is a reposting of what I wrote on the Acquia Dev Center blog in 2016, Should I disable PHP warnings and notices?.

Drupal onscreen logged PHP error messages and warnings

Many developers who work on Drupal (or other web/PHP) projects have error reporting disabled in their local or shared dev environments, for a variety of reasons—some don't know how to enable it, some are annoyed by the frequency of notices, warnings, and errors, and some don't like to be reminded of how many errors are logged!

There are a few important reasons you should make sure to show all errors when developing, though:
