 When a radio wave hits an antenna, the electrical component of the wave induces a difference of potential in the conductor which gives rise to an electric current. This is called electromotive force. The current induced is normally small, therefore, we usually design antennas to be as efficient as possible.

 One way to distribute to different Linux distributions is to compile the source under each of them and distribute it separately.  This can be a pain to manage if you target multiple distributions and multiple versions of those distributions. Instead, let's take a look at AppImage. This allows us to package up our binaries and shared libraries under one file which we can distribute.

 There is an event in Computer Security called "Capture The Flag". The purpose is to test the skills of security engineers and students through a variety of tasks in order to get a pass phrase which is called a flag. I noticed that Dr. Andrew Marshall wanted to set up this event at the University of Mary Washington for a while, so I and a few others decided to help make this a reality for him.

 Mastodon is a cool federated micro-blogging platform that can serve as an alternative to Twitter. One of its primary features is that it shows what they call toots from only people you follow in reverse-chronological order. Nowadays, large tech companies employ recommendation engines to surface content from users (you don't even need to follow) in a non-chronological order driven by the number of interactions users similar to you had with the content. The lack of recommendation engine in Mastodon can be a blessing as low-quality emotional content tends to drive more interactions. However, this can also be a curse as cool new people don't naturally surface in your feed. The following are the techniques I employ to consistently seek out cool new people:
