You don’t want to be on Cloudflare’s naughty list
My home IP ended up on Cloudflare’s naughty list for six days. Most websites and many apps loaded slowly, partially, or not at all. Just had to wait it out.
<p>I don’t know what I did wrong, but I’ve angered one of the titans of the internet! For the last six days, my home internet connection has been partially broken. Some apps and many websites either load slowly, partially, or not at all. Everywhere I go, I’m greeted by the same blockade message from Cloudflare.</p> <p><a href="https://www.ctrl.blog/entry/cloudflare-ip-blockade.html">Read more …</a></p>

Can you use a WebP file as an Open Graph Protocol image?
Do you still need to maintain webpage thumbnails/link previews in legacy image formats, or have apps caught up with the WebP revolution? It’s a bit complicated.
<p>The Open Graph Protocol (OGP) was created by and for Facebook in 2010. OGP is a pseudo-standard set of metadata tags you can include on your webpages to describe its contents. By now, it’s become the primary data source for generated link previews across the web and apps.</p> <p><a href="https://www.ctrl.blog/entry/webp-ogp.html">Read more …</a></p>

Brave reduces the page load performance cost of its adblocker
The Brave browser has significantly cut the page load time overhead of its adblocker. Brave loaded pages slower than competing browsers without adblockers.
<p>An adblocker doesn’t necessarily make your web browser load pages faster. The Brave browser introduced a shiny new and more performant adblocking system in late 2019. However, leftovers from its old system have remained in the browser and have quietly held back its performance potential.</p> <p><a href="https://www.ctrl.blog/entry/brave-ab-performance.html">Read more …</a></p>

Google’s unfair performance advantage in Chrome
Google Chrome gives Google Search (when set as the default search engine) a network performance-boost over competing search engines.
<p>Google Chrome for Android has a feature that gives Google Search an unfair advantage over its competition. Sure, it’s the default search engine and that’s a huge hurdle to overcome for any competitor.
