3D Printing The first few weeks

Friday, April 20th, 2018

In February I finally got a Prusa i3 Mk3 3D printer that was ordered in December, a very late Xmas gift. I had struggled with a MakerBot Replicator previously, but based on my research, I had high hopes for the Mk3.

This is the story of the first few weeks of 3D printing and what I learned.


Filebeat on OpenBSD 6.2

Sunday, March 25th, 2018

I recently installed a new of OpenBSD 6.2 server. As part of that install, I needed to install Filebeat to forward logs to an ELK server (Elasticsearch, Logstash and Kibana).

The following steps assumes you have installed OpenBSD 6.2 and will cover dependent package and Filebeat installation, and configuration of Filebeat.

Would you like to use a remote control to control your computer? How about using your computer to send remote control signals to your TV or Stereo instead of using the remote?

This is the fourth in a series of posts where I will describe how to use a Raspberry Pi, Raspbian and Linux Infrared Remote Control (Lirc) to receive and send infrared remote control signals. This post will be focused on how to trigger applications and depends on Linux Infrared Control Part 1: Receive IR and Linux Infrared Control Part 2: Send IR.
