Python includes some helping support for classes that are designed to just hold some data and not much more: Data Classes . It uses plain Python type definitions to specify what you can have and some further information for every field. This will then generate you some useful methods, like __init__ …
We like to revisit the discussion about simple git tags used for Debian uploads.
Debian Salsa updated to GitLab 13.7 with several new features.
Debian Salsa updated to the recent GitLab 13.5 release with several new features.
Got a bleeding ThinkPad X13 with Windows. Need Debian.
Today, Salsa hosted it's 1,000,000th CI job. The price for hitting the target goes to the Cloud team . The job itself was not that interesting, but it was successful.
There is a large disagreement inside Debian on how a git repository used for Debian packages should look like. You just have to read debian-devel to get too much of it. Some people prefer that the content of the repository looks like a "modern" (3.0) source package the Debian …
It's been some time that someone at Google told us that they had problems providing a stable mirror of Debian for use by their cloud platform. I wanted to give it a try and see what the platform can give us. At this time I was already responsible for the …
Providing working network is not easy. Providing enough troughput is not easy either.
For years I used a working blog setup using Zope , Plone and Quills . Quills was neglected for a long time and made me stuck at the aging Plone 4.2. There seems to be some work done in the last year, but I did not really care. Also this whole …
Almost all existing documentation tells me how to setup Ceph with one or two layers of abstration. This entry shows how to set it up by hand without needing root permissions. Components Ceph consists of two main daemons. One is the monitoring daemon, which monitors the health of the cluster …
Linux includes a syscall filter since a long time. It was restricted to a pre-defined set of syscalls. Since some versions Linux got a more generic filter. Linux can use a BPF-filter to define actions for syscalls. This allows a fine granular specification on which syscalls to act. Also it …
For some, LDAP, just like X.500, is black magic. I won't argue against. Sometimes it really shows surprising behavior. It always makes sense, if you think about what LDAP is built for. One surprising behavior is the handling of the " Insignificant Space " LDAP supports syntax and comparator methods. The …
I use UUCP to get my mails. It works fine but lacks support for modern SMTP features like DSN. While it may be possible to bolt support into the the rmail part, both the sendmail interface used to submit mails and the Postfix pipe daemon used to extract mail are …
I still prefer to handle all my mails at home. I got backup set-up on my own and have anything in direct access. This network is connected to the internet via an end-user DSL connection without a static IP-address and without any useful SLA. However relaying mails over such an …
Today I found out that the DNS-Server at home is used for a DDoS against a DNS-Server. The attackers send a small query, "ripe.net ANY" in this case, with a faked sender IP. The DNS-Server answers with a much larger packet to the (faked) sender. Because the domain is …
I installed a Lenovo Thinkpad X130e with Wheezy. UEFI The X130e does not want to boot via BIOS emulation. The Wheezy D-I installs only BIOS Grub. It does not provide the selection to use EFI at all. So the initial installation was BIOS only and EFI refused to boot it …
AoE is one of the protocols supported by Linux to access storage via network. It uses plain Ethernet for communication and includes a discovery mechanism to find all available targets. I use it to provide disk space to VMs running on different machines. Next step is to boot via AoE …
