  • Manual letsEncrypt for CPanel

    Jump to Renewal Instructions Additionally, EFF has deprecated use of aptitude/yum/dnf/etc package managers for deploying Certbot on Debian-based systems. Instead, they recommend use of Snap. At work I recently collaborated with our hosting provider to move our company website to a version of cPanel. Up until this time, there has been no way of running our site on…

  • DMX for actual Electrical Engineers

    So it’s been coming up recently that our church media department has been buying “OpenDMX USB Dongles” for upwards of $80. I was mortified, especially after seeing this USB device, opening up the sheet metal project box and finding it to be a simple 2-stage USB to RS-485 protocol bridge with no programmable intelligence whatsoever.

  • LetsEncrypt List of Useful Commands

    Here are a few letsencrypt commands that I’ve found useful in the past few months of trying it out.

  • Embarcadero TThread Works Just Fine

    I’ve been annoyed for a large amount of time (years in fact) over some of our software we use and sell. In essence, what we have is a TCP GUI that communicates on a 250ms timer with a microcontroller that’s serving up a two-way communications protocol over ModBus FC23 – we send commands either to…

  • Expired Domains – A Headache (but a learning experience)

    Hey all! It’s been a few months, I know. But I wanted to share an experience I had with my recent domain name headache. So as you may or may not know, I’ve owned ppsstudios.com since May 2013. I purchased it via Google Apps which in turn set my registrar to eNom. Both are useful services and work…

  • OpenVPN

    New project at work! Setting up OpenVPN. It’s great fun…except when it doesn’t work. I love the Windows interface for setting up the Server. It’s straight-forward, and following the tutorial at http://openvpn.net/index.php/open-source/documentation/howto.html works like a charm. Setting up the client is just as easy, and the connection can be made in a matter of minutes.

  • Ruby on Rails – Success kinda!

    Okay. I’m totally going to try this again, just to see if I can’t figure it out. Ruby on Rails – A ruby based framework for web stuff. Basically, I haven’t a clue, but I’m going to at least try to get it running on Windows and make some rudimentary website things, just to see…

  • Petra

    So a few weeks ago, I was doing cameras at church. Or maybe it was during the 6:33, our Tuesday men’s group. In either case, the subject was brought up in the sermon that after Jesus’ crucifiction, Peter had denied Jesus three times, and all that, he basically got really depressed, dropped his calling and…

    AR.Drone – Infrequently Asked Questions

    Just recently (like, yesterday), I received my first (and hopefully long-lasting) AR.Drone 2 from Parrot in the mail! This thing is a four-rotor remote-controlled copter operated with an app on my Android! So far, I can say I’m fairly happy with it, save for the stock battery which, in short, is really really sad. However, with a…

  • PLC and Hardware Control

    Take a survey related to the following Aha! Thank you, Dad for my new Arduino hardware controller (and the partially-outfitted Craftsman toolbox to make my life simpler when building stuff)! Easy easy to program, and easier to wire up! There was a time a few years ago that we were playing with a Seimen’s PLC at my old job,…
