Just kidding! Install the October 2025 SU first; then turn off your servers.

You all know I like to use the internet.nl internet standards test. Recently they added the Certificate Authority Authorization or CAA DNS record check. This record signals which CA is allowed during the certificate request process and CA's should only issue a certificate when it's listed.
Internet.nl adds CAA test and announces TLS test changes
Test for modern Internet Standards IPv6, DNSSEC, HTTPS, HSTS, DMARC, DKIM, SPF, STARTTLS, DANE, RPKI and security.txt

@jessiegender has received more hatred and vitriol in her career simply for being a trans person daring to exist in a public space.

This #Microsoft365 Message Center #MC1131064 hurt a little: Microsoft Lens app will retire. Starting this September in phases and concluding on 15 December 2025. The replacement app is the Microsoft365 Copilot app, although it certainly does not have feature parity with Lens

Vandaag liet staatssecretaris Struycken weten dat het kabinet tóch het wetsvoorstel voor een betere Transgenderwet gaat intrekken. Eerder had het kabinet juist aangegeven dit niet te willen doen.
Dat ze nu juist als demissionair kabinet besluiten dit wetsvoorstel toch in te trekken is ongehoord.
