Day -1 Day 0: Devsprints Day 1 Day 2

In this post, I will tell you how to fix “Failed to load SELinux policy. Freezing” issue and reboot your Fedora with SELinux set to Enforcing. It was the first day of Flock 2016, when I was working on my demos, that my laptop failed to boot after a bad system halt. The error was: systemd[1]: Failed to load SELinux policy. Freezing. I was running Fedora 23 on my laptop with SELinux set to enforcing.

Today, I will be speaking about a typical, healthy and active day from my life. This is about a lifestyle I was able to attain and sustain, discovered during the course of my journey to become fit and stronger. Some time ago, I was leading a very undisciplined life, working day and night, eating whatever’s palatable, and I was getting fatter and fatter, reached up to 83 Kgs. Around 2 years back, I started my journey to become fit and get back into shape. I started working out at the gym, experimenting with my diet: eating less, eating more, eating right stuff. After going through hell lot of pain, I came to a point where I was able to see the results: reducing weight and waist line, feeling fit and strong, when I became self motivated to work out daily and follow proper diet and sleeping pattern. I reached a weight of 65 Kgs some months back and I have been maintaining it since then. The best part about it is the feeling of being active and fit throughout the day. ...

Today, I migrated my Ghost blog to a Docker container running on CentOS 7. The config and content data for the blog has been pushed to https://github.com/rtnpro/rtnpro.com. The setup was pretty simple. git clone https://github.com/rtnpro/rtnpro.com cd rtnpro.com # Allow sharing this directory with a Docker container sudo chcon -Rt svirt_sandbox_file_t ./ # Allow nginx access port 2368 expose from Docker container sudo semanage port -a -t http_port_t -p tcp 2368 # Run container sudo docker run -d -ti -p 2368:2368 \ --name rtnpro_com_ghost \ -v $(pwd):/var/lib/ghost \ -v $(pwd)/themes:/usr/src/ghost/content/themes \ -e NODE_ENV=production \ ptimof/ghost cp nginx.conf /etc/nginx/conf.d/www.rtnpro.com.conf sudo service nginx restart And, tada! I have my blog running inside a container now.

We have started working to power realtime IRC chat on Fedora Hubs pages, using Waartaa. We plan to load the Waartaa chat widget as an <iframe> inside Fedora Hubs. The user story we are looking forward to create is as follows. A user logs in to Fedora Hubs using his FAS account. He then creates a network connection to IRC and connects to the IRC server. Under the hood, it will run an ircb bot for the user’s IRC connection in waartaa. The user can now chat on IRC from Fedora Hubs pages, or, from an IRC client of his choice, simultaneously, using the same IRC nick. ...
