    PHP 8.1 is available off the shelf in openSUSE Tumbleweed. I will shortly prepare a PHP 8.1 / tumbleweed version of the maintaina Horde containers. These will initially be broken due to some outdated language constructs. As PHP 7.4 will EOL by the end of this year, I decided not to bother with PHP 8.0…

    Our Horde docker images have switched over from Tumbleweed to openSUSE LEAP once again. Recently our container build CI job in github.com broke down unexpectedly. An investigation showed that Tumbleweed’s core libraries, especially libc, were too new for the CI’s build system, based on Ubuntu LTS. This is the second time we abandoned the Tumbleweed…

    Since Horde 4, the Horde ecosystem heavily relied on the PEAR infrastructure. Sadly, this infrastructure is in bad health. It’s time to add alternatives. Everybody has noticed the recent PEAR break-in. A security breach has been found on the http://pear.php.net webserver, with a tainted go-pear.phar discovered. The PEAR website itself has been disabled until a…

    Hallo, I just had a little struggle getting the current tumbleweed to run on the original Raspberry Pi (first generation, though the revision with larger RAM). Just in case this helps anybody: I did not have any luck with a fresh openSUSE Tumbleweed image of one of the current arm6 builds. Don’t know why. Here’s…

    Trustr is my current project to create a simple certificate management app. I decided that it is just about the right scope to demonstrate a few things about application development in Horde 5. I have not made any research if the name is already occupied by some other software. Should any problems arise, please contact…

    A colleague of mine recently faced difficulties to upload large opensource DVD images (>4G) into ownCloud during a demonstration. After some analysis, it turned out that it wasn’t ownCloud’s fault at all: PHP itself simply could not cope with large file uploads due to an overflow in some key variables. Further research showed that this…
