Opt-out of LinkedIn’s AI scheme now (last day Nov. 3rd 2025)

by

If you prefer your content/ data not to be used to train LinkedIn’s AI, you can opt out at https://www.linkedin.com/mypreferences/d/settings/data-for-ai-improvement (but only until tomorrow, Nov 3rd?).

Crazy that this requires an explicit opt-out by the way, it really should be opt-in (so off by default).

More info about this can be found at tweakers.net by the way.

Feel free to share 😉

HTTP/2; do not aggregate? Well, maybe …

by

Ever since the advent of HTTP/2 people asked if they still needed JS/ CSS files to be combined and indeed by default aggregation is off in Autoptimize. But based on this interesting article by Harry Roberts, “bundling is here to stay for a while”. So when in doubt; test performance with and without aggregating CSS/ JS ideally both on mobile and desktop bandwidth profiles and learn which works best for your site! 🙂

As found on Our Tube; Edward November – Cold Street Light

by

So I heard Edward November on the (online) radio a couple of times already and the first and only single “Cold Street Light” is magic.

He (aka Edmund Lauret) should either stop making music entirely or (a lot more difficult) he could try to do even better.

The latter will be very hard though, because “Cold Street Light” is a perfectly unhappy pop-song, beautifully moody, slightly quirky and somewhat unpredictable but with an immensely catchy (downbeat) chorus.

Want to know some Autoptimize secrets?

by

There’s a first for everything and so last week I did a presentation at a WordPress Meetup in Antwerp titled “Autoptimize: 5 secrets and an intermezzo” which at least I had fun with.

You can find a PDF export of the presentation here.

Questions go below, in the comments (or in the form on the contact page).

Autoptimize Pro 1.3; instant.page

by

New booster in Autoptimize Pro 1.3: instant.page, a 3rd party JS component that can significantly improve performance for visitors going from one page to another on your site by preloading a page based on visitor behavior.

Do take into account that it could increase the number of page requests as the preloaded page might end up not being requested after all.

Mastodon oEmbed requests overload; use WP Rest Cache

by

Mastodon due to the decentralized nature can result in a significant extra load on your site if someone posts a link to it. Every Mastodon instance where the post is seen (which can be 1 but also 100 or 1000 or …) will request not only the page and sub-sequentially the oEmbed json object to be able to show a preview in Mastodon. The page requests should not an issue as you surely have page caching, but the oEmbed object lives behind /wp-json/ and as such is not cached by page caches. The solution; the WP Rest Cache plugin and one small code snippet (for now). A lot more info can be found in Donncha’s excellent post on the subject.
