How CDNs Generate Certificates. Thomas Ptacek (now at Fly) describes in intricate detail the challenges faced by large-scale hosting providers that want to securely issue LetsEncrypt certificates for customer domains. Lots of detail here on the different ACME challenges supported by LetsEncrypt and why the new tls-alpn-01 challenge is the right option for operating at scale. # 26th June 2020, 12:03 am

It’s interesting to me how much [Closure] feels like a more advanced version of Dojo in many ways. There’s a familiar package system, the widgets are significantly more mature, and Julie and Ojan’s Editor component rocks. The APIs will feel familiar (if verbose) to Dojo users, the class hierarchies seem natural, and Closure even uses Acme, the Dojo CSS selector engine.

Dojo 1.3 now available. Looks like an excellent release. dojo.create is particularly nice—I’d be interested to know why something similar has never shipped with jQuery (presumably there’s a reason) as it feels a lot more elegant than gluing together an HTML-style string. Also interesting: you can swap between Dojo’s Acme selector engine and John Resig’s sizzle. # 1st April 2009, 12:19 am
