In the second part of this series I described how to unlock a base level of performance out of your Joomla site with a few, simple changes. Today we're diving deeper into static media: JavaScript, CSS and image files. These changes are more involved but can turn a junker of a slow site into a decently performing one. Arguably, not all of these changes make sense for all sites but the performance benefits you get are substantial.

In the first part of this series I described why tuning the performance of your site is something you should do for both philosophical and practical reasons, as well as where to start. That post was by necessity a bit generic. In the second part of this series we'll dive into some of the basic things you can do in Joomla to unlock a decent amount of performance.

Joomla is a very good CMS out of the box. It is reasonably fast, it has built-in support for structured data and even caching. Yet, it has an unwarranted bad reputation about being slow and bad for SEO. In this series of articles I will tell you how you can tune a Joomla 3 site to improve its SEO and PageSpeed score and how to avoid all the pitfalls when building your or your client's site. The end result is a site that's appealing to both search engines and living, breathing site visitors.
In this first part of the series we'll talk about why this is important, in general, and what are the obvious first steps you can take to get to that goal.

The past few weeks the PHP world is abuzz with Expose, an Open Source alternative to ngrok. If you're not familiar with either, they both let you share a site hosted on your local web server using a subdomain that can be accessed over the Internet. This is great for sharing a site with your client, testing HTTPS behavior with a valid TLS certificate, developing social media / SSO integrations, testing sites on real mobile devices etc.
Expose lets you run your own server for the full white label experience. It's also free of charge – except for the cost of running your own server, of course. In this article I'll tell you how to create your own Expose server and share your Joomla site with it.

Over the last few years I have standardized my access to remote servers, including GitHub, using a GPG signing subkey as the authentication credential. Having this stored in secure YubiKey hardware and locked behind a PIN is a step up in security; authenticating to the remote resource requires physical possession of an unphishable hardware token and knowledge of a PIN. Moreover, this allows me to sign GPG commits and tags.
While I had set this up on Linux and macOS since 2017 I only had the time and patience to do that on my tertiary machine, a Windows 10 one, in late 2019. I had to redo everything last week and I realised I couldn't remember a few non-obvious but critical steps. Hence this article where I explain how to combine a YubiKey, GPG4WIN, PuTTY and Git for Windows on Windows 10 to access your GitHub account – and any SSH server – securely and sign your commits.

When you're thinking of a development, local web server with PHP you're probably thinking of an AMP stack: Apache, MySQL and PHP. In some cases your live environment may dictate using Microsoft Internet Information Services (IIS) -- typically the case with corporate deployments or when you're working with a client that's invested in the Windows platform. In those cases you are better off using IIS yourself to prevent nasty surprises from discrepancies between your local and live environments, most notably the fact that IIS does not understand .htaccess files.
In this article we will see how to create a local IIS development server on Windows 10 Professional with multiple versions of PHP and MySQL.

Developing PHP applications which support a variety of servers and environments requires me to occasionally develop on Windows. The first thing someone notice when switching from Linux or macOS to a Windows machine for PHP development is that it's so darned slow. Even on the exact same machine, Linux is a good 2x to 5x faster than Windows. Most of the sluggishness observer, however, is down to configuration and can be mitigated. This article explains some of the tricks I used to make PHP faster on my Windows development machines.
