People are talking how #Xbox Game Pass Ultimate is increasing in price by 50%. Whilst true, it's actually a 75% increase on what I was paying a year ago, here in the UK. And a 110% increase on what I was paying 2 years ago.

Jeff Fortin doubles down on this insane idea that is apparently prevalent at GNOME that security vulnerabilities in dependencies can be ignored indefinitely as long as a bug report exists. Never seen this opinion outside of GNOME. gitlab.gnome.org/GNOME/geary/...

Finally got around to creating my "Bad Email Clients" page - www.emailprivacytester.com/badClients - I will update it with more clients in time.

Email clients Balsa and Geary are also vulnerable to the link preconnect privacy issue I recently blogged about in Evolution Mail. Although not to the dns prefetch one. New bugs at gitlab.gnome.org/GNOME/geary/... and gitlab.gnome.org/GNOME/balsa/...
Making sure you're not a bot!

I've added a new test to the Email Privacy Tester www.emailprivacytester.com/testDescript... - This one gives you the client IP of Evolution Mail users prior to clicking "Load Remote Content". May affect other clients too.

Always fun to get an update on a Mozilla Thunderbird security bug I reported 13 years ago. Finally changed from Status: new to Status: assigned. By some automation though so probably doesn't mean anyone will actually look at it - bugzilla.mozilla.org/show_bug.cgi...
700979 - Can force webpage links to open in Thunderbird Tabs
ASSIGNED (mkmelin+mozilla) in Thunderbird - Message Reader UI. Last updated 2025-04-07.

After years of self hosting NextCloud, and before that OwnCloud, I have finally migrated to Radicale. Running a humongous php app when all I wanted was calendar and contacts sync never quite sat right with me. Syncthing has been there for my file syncing needs.

Copilot just randomly suggested I leave a comment "This is a bit of a hack but it works" next to some code I wrote

Realised I'd accidentally left a Twitter link on www.emailprivacytester.com. Gross. Removed with haste.
