  • Mercedes-Benz previews its operating system MB.OS
    Is this using Jolla's Android AppSupport? https://jolla.com/ I use a Sailfish OS phone and it works amazingly well. I know they have been pushing hard into the auto industry after pulling out of Russia because of the war. I would be very pleased if Mercedes is helping fund Jolla. - Source: Hacker News / about 1 year ago
  • Jolla.com down?
    Anybody got any intel on why jolla.com is down? I purchased the Sailfish OS licence for Xperia 10 ii but the links to installing instructions are nowhere to be found. Source: almost 2 years ago
  • The Deceptive PR Behind Apple’s “Expanded Protections for Children”
    There was one but people wouldn't "put their money where their mouth is". The Jolla phone was made by ex-MeeGo/Maemo devs from Nokia, but nobody bought them. Now they're focusing on just the OS and they don't make any full fledged devices: https://jolla.com/. - Source: Hacker News / over 2 years ago
  • On Apple's “Expanded Protections for Children” - A Personal Story
    Sailfish OS is mobile Linux and can run on smartphones. I didn't personally use it but the website claims to in on the Sony Xperia 10 II from 2020. It costs $50, though. https://jolla.com. - Source: Hacker News / over 2 years ago

    What website did you go to? KaiOS is not dangerous. I'm dubious that their official site (kaiostech.com) would have trojans or malware on it... Source: 6 months ago
  • LetsEncrypt Cross-signing Expiry
    LetsEncrypt ISRG Root X1's IdenTrust DST Root CA X3 cross-signing has come to an end. This means that any device/browser (including KaiOS devices) which doesn't yet trust the ISRG Root X1 will no longer trust any site with a LetsEncrypt certificate (which, by the way, includes kaiostech.com!).
