OMD (and probably a lot of other packages) depends on mysql-server, so we can’t just use mariadb-server easily. Or can we? Sure, we can rebuild the whole OMD thing with different dependencies, which will take a while. Or, we can just create a meta-package called mysql-server, which just depends on mariadb-server and satisfies the dependency for OMD. I do not care about packaging hell, i just use fpm, which requires ruby. Also i do not want to mess up my system, so i just use docker. Read more

Utilizing some projects, you can achive a nice branded CI/CD Ubuntu: preseed-cinnamon-ubuntu plymouth-logo-theme-template lightdm-logo-theme-template

Same like bower, it might happen that you need to build things not only locally but also in some sort of CI. Deploying a npm proxy cache is fairly easy. Installation I suggest to add a specific user for this: useradd -m -d /var/cache/npm -s /bin/false npm Some neccessary packages: apt-get install nodejs You probably want to fetch the latest packages. Now we install the cache: sudo -u npm /bin/bash cd npm install npm-proxy-cache Startup /etc/systemd/system/npm-proxy-cache.service [Unit] Description=npm proxy cache After=network.target After=syslog.target [Service] RuntimeDirectory=npm-proxy-cache PIDFile=/var/run/npm-proxy-cache/npm-proxy-cache.pid WorkingDirectory=/var/cache/npm ExecStart=/var/cache/npm/node_modules/npm-proxy-cache/bin/npm-proxy-cache -e -h %H Restart=always RestartSec=10 StandardOutput=syslog StandardError=syslog SyslogIdentifier=npm-proxy-cache User=npm Group=npm [Install] WantedBy=multi-user.target Client usage npm config set proxy http://npm-proxy-cache.example.com:8080 npm config set https-proxy http://npm-proxy-cache.example.com:8080 npm config set strict-ssl false

If you’re using bower for some of your projects and may happen to build this not only locally but also in some sort of CI, you might want to have a bower caching proxy in your network. Installation I suggest to add a specific user for this: useradd -m -d /var/cache/bower -s /bin/false bower Some neccessary packages: apt-get install git python-virtualenv Now we install the cache according to the README. sudo -u bower-cache /bin/bash cd virtualenv . . bin/activate pip install -U pip setuptools pip install bower-cache Configuration sudo -u bower-cache /bin/bash cd bower-cache-init /var/cache/bower/cache cd cache python manage.py changepassword admin We also need to adjust some variables which gets served to the clients.

If you have multiple clients connected to a jabber server with XEP-0280 enabled, you may want to receive all messages on all clients. ATM, Pidgin does not support this, but there’s a patch available. I’m just picking up this comment on how to build it: mkdir -p ~/pidgin docker run --rm -ti -v ~/pidgin:/pidgin -w /pidgin ubuntu:xenial /bin/bash apt-get update apt-get install curl dpkg-dev -y apt-get source pidgin apt-get -y build-dep pidgin cd pidgin-* curl -O https://developer.pidgin.im/raw-attachment/ticket/15508/carbons.5.patch patch -p1 < carbons.5.patch dpkg-source --commit dpkg-buildpackage -us -uc Just adjust the docker image tag to the ubuntu version you use (i always use LTS ). You can find prebuilt packages here in my repo. Read more
