    Use mu-plugins for adding custom functionality to your WordPress site

    If you google “functions.php” you get about 7 million results. I bet most of them contain bad advice: “How to add functionality to your WordPress site”. Some of them continue even worse: “\[…\] without using a plugin”. For your own good, don’t edit functions.php to add custom functionality to your WordPress site. You can use mu-plugins to do that.

    Don’t be “clever” with the translatable strings in your WordPress plugin or theme

    Since I translate a lot of WordPress themes and plugins, I sometimes come across plugins who try to be clever with their translations. This tends to not work so well in reality.

    Do people struggle with Yoda conditions for real?

    I’ve been using, and advocating for others to use, Yoda conditions for a long time. Sometimes, I read or hear about someone who doesn’t like them, without actually describing why. From time to time I read a blog post that advocates against it: And it’s always the same reason.

    A reference of all outgoing WordPress emails

    As you may know, WordPress sends out email notifications from time to time. Actually, as of WordPress 4.8.1, there are 24 different occasions when WordPress will send an email message. Don’t you think it would be useful to have a reference of all outgoing WordPress emails?

    The bus factor in the WordPress project

    During WordCamp Europe 2017 in Paris, there was a Q&A session with Matt Mullenweg. I wanted to ask him a question, but due to high demand and restricted time, I never got to ask him. I guess Matt is a busy person, so I don’t expect him to actually answer this question himself. But maybe someone in the WordPress community has answers, insights or ideas? A person is the CEO of one of the most important WordPress-related companies.

    Proper RFC 4122 UUIDs as GUIDs in WordPress

    UUIDs (Universally Unique IDentifier), also known as GUIDs (Globally Unique IDentifier), is a string that identifies a piece of information in computer systems.

    Secure email: Encrypt and sign your emails with PGP/GnuPG

    Email is fundamentally insecure. There are such a plethora of issues with it, it is crazy to think about the kind of information sent with it. It is probably even crazier when you realize we’ve had a solution for sending secure email since 1991.

    Six reasons why I love WordCamps

    This weekend I was at WordCamp Berlin, met a lot of great people, and watched a lot of interesting presentations. WordCamps are actually quite informal by themselves, but at the afterparties, people are really letting their shoulders down and it often seems like people are long-time personal friends. If you open up to it, it won’t take long until people will give you feedback on whatever you have released in public.

    DNS privacy: Use a DNS provider that doesn’t track you

    Many ISPs and other DNS providers are slow or inject ads, track you, hijack DNS queries or do other nasty stuff. To mitigate this, you should use a fast, reliable and free service that respects your DNS privacy.

    This is the second post in my series of posts on some of the tools I use to stay a little safer and protect my privacy online. With self-destructing cookies, you get a clean sheet even with those who don’t respect the Do-Not-Track header.
