So long Disqus, hello Webmention
▻https://nicolas-hoizey.com/2017/07/so-long-disqus-hello-webmentions.htmlI’m fed up with Disqus. It’s been useful, easy to plug on this blog, but it’s a mess for web performance, and I don’t own my data, so… bye bye. Webmention is now a great alternative, with more people implementing it, so let’s try to keep only that.When I launched this Jekyll based site a while ago, I didn’t put any comment system, because I didn’t like any of the options available at the moment.Later, I was missing the interaction I had on my previous dynamic blog powered by SPIP, so I jumped in the Disqus train, because it was the most used around me, and on the sites I visited.Installing Disqus on a blog only requires a few lines in the post template, with two JavaScript variable to set with Liquid values.

The Website Obesity Crisis
►http://idlewords.com/talks/website_obesity.htmIf present trends continue, there is the real chance that articles warning about page bloat could exceed 5 megabytes in size by 2020.

Il est gentil pour son exemple Medium avec 1,2 Mo : moi quand je lance le test de poids de Firefox ça me dit :
– sans mise en cache : 2212,17 Ko
– avec mise en cache : 44,37 Ko -
Moi aussi j’avais des résultats divergents (mais j’avais pas pensé aux bloqueurs de pubs et autres machins aui amaigrissent les pages) mais là, 2217 ko et 2,2 mo c’est kif kif non ?

nan lui c’est 1,2 Mo
et moi 2,2 (avec microblock en plus) -

bah oui, c’est ce que je dis depuis le début : « il est gentil » ! :D

Et sinon, mis à part ça, tous ses commentaires sont assez drôles, que ce soit sur les romans russes ou encore sur les images de Taft.
Does your page design improve when you replace every image with William Howard Taft?

Everything else is bullshit.

Deploying New Image Formats on the Web
►http://www.igvita.com/2012/12/18/deploying-new-image-formats-on-the-webIf we really want to make an impact on web performance, then image formats is the place to do it. There is absolutely no reason why we shouldn’t have dozens of specialized formats, each tailored for a specific case and type of image. But before we get there, we need to iron out some kinks...
