Programming on the Road

I've been traveling for work recently and kicking myself for not bringing an RMC3 along. It's not that I enjoy Crestron programming every waking minute of the day. A lot of times, I try to test programming out before I ship it off to someone as a "fix." As control system programmers, we're in a … Continue reading Programming on the Road →

VirtualBox Headless

Collected from the wonderful documentation at https://www.virtualbox.org/manual/ch07.html. To see which VMs are available, type: $ VBoxManage list vms "dev-site" {2e39d6cc-c307-44f6-b73e-a6f95e0f17b0} To only see running VMs, type: $ VBoxManage list runningvms And to start it: $ VBoxManage startvm "dev-site" --type headless Waiting for VM "dev-site" to power on... VM "dev-site" has been successfully started.

Analyzing Web Traffic

I have another website at dev.kielthecoder.com that isn't used for much. But I was curious who might be visiting it and where they come from. I'm not doing any cookies or session tracking, so I only have the server log files to go off of. I want to demonstrate some UNIX commands that can be … Continue reading Analyzing Web Traffic →

VC-4: Websockets

This post picks up right where the last one left off. I got VC-4 running on an RHEL instance, but now we're back to some of the challenges that VC-4 brings... like printing to a console window. Better Logging Control Concepts has an excellent Websocket Server demo available on the Application Market. If you open … Continue reading VC-4: Websockets →

VC-4: RHEL 8

The last time I wrote about VC-4, it was still based on Ubuntu 16.04. Crestron released an update around December 2020 that switched to Red Hat Enterprise Linux (RHEL) 8. I cut my teeth on Red Hat Linux 5, and once we had faster DSL Internet at home, I tried out a number of other … Continue reading VC-4: RHEL 8 →

Merging .pacnew Files

I have a couple Linodes running. My mail server is powered by Arch Linux, and I always forget to check if new configuration updates need to be applied. I'm not a professional IT admin, so when things are working, I tend to leave well enough alone. A quick way to locate configuration updates that were … Continue reading Merging .pacnew Files →

Upgrade Complete

I got impatient waiting for Ubuntu 20.04.1 to release (my fault, not the devs). So I upgraded and it was painless! Good job, Ubuntu devs!

Upgrading Ubuntu 18.04.4 to 20.04

My home NAS / Plex server is currently running Ubuntu Server 18.04.4. I have no plans to upgrade until Canonical releases 20.04.1, but in the meantime I wondered if I could run through the procedure in a VM to see if there are any gotchas going from 18.04.4 to 20.04. I'm also using LVM to … Continue reading Upgrading Ubuntu 18.04.4 to 20.04 →
