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> urn:uuid:e48ef64a-6199-4e6e-a159-7162fd46e1e3 2021-09-26T11:19:00Z 2021-09-27T04:12:00Z 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> urn:uuid:99578e3e-0096-434e-81b7-10efe3fe2927 2021-07-07T14:06:00Z 2022-01-02T19:16:00Z 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. However, Chrome also reserves a performance-boosting feature for Google Search exclusively.</p> <p><a href="https://www.ctrl.blog/entry/chrome-google-dse-preconnect.html">Read more …</a></p> urn:uuid:08f69157-4809-4616-a48c-2a402f388b33 2020-12-16T09:21:00Z 2021-09-16T19:43:00Z A technical and privacy review of Cloudflare Web Analytics Cloudflare has launched a new free web analytics/visitor-counting service. It promises to put end-user privacy first. The service has plenty of room to improve. <p>Last week, Cloudflare announced its new Web Analytics service: a cost-free stand-alone product for counting website visitors. In its announcement, Cloudflare promised that its new service puts privacy first, doesn’t collect any personal information, and doesn’t use persistent tracking such as cookies.</p> <p><a href="https://www.ctrl.blog/entry/review-cloudflare-analytics.html">Read more …</a></p> urn:uuid:bff9371d-fc07-43f8-be7d-288af99a6078 2020-11-30T22:43:00Z 2020-11-30T22:43:00Z Chrome to remove HTTP/2 Push Chrome intends to remove support for server push; an underutilized performance feature introduced in HTTP/2. It cites low usage and implementation complexity. <p>Chromium developers have announced that they plan to remove support for HTTP/2 server push from the market-leading browser engine. Server push lets web servers preemptively send clients resources it expects them to request later. The technique can reduce the number of network round-trips required before the client has all the resources it needs to display a page. The announcement cited high implementation complexity, low adoption among websites, and questionable performance gains as the reason for the removal.</p> <p><a href="https://www.ctrl.blog/entry/http2-push-chromium-deprecation.html">Read more …</a></p>
