Finally got Docker installed and working.
xLights
xLights [v4.2.25 Beta] working great…except Effects icon very tiny under the Sequencer tab. Posted problem in the xLights Forum under Bugs. Turns out there is a “Tool icon size” setting under the the Settings tab that fixed this. So technically it wasn’t a bug, however I can’t imagine the Small setting being useful for anyone. …
Christmas Light Shows
Have been getting interested in creating Christmas Light Shows [lights or individually programmable pixels synchronized to music] recently…tis the season. Spent a couple hours just watching FPP and xLights/Nutcracker videos. I have a Pi and find this Christmas light Show technology very interesting. Especially Linux only solutions using Raspberry Pi running the FPP [Falcon Pi …
judoplaces
Rewrote judoplaces from MS-Access to SQLite/Python. Wow my brain really atrophied from lack of programming. It took me forever to find a simple error that Python was complaining about.

Lazarus/GAMBAS
09/20 – Really want Lazarus working. Also have a big curiosity [probably because I’ve used MS-Visual Basic] about Gambas [see farther down below]. So I feel some changes in Mint 18 along the way may have caused the problem. So I decided to Clonezilla what I have, then reinstall Mint 18. Lazarus still seemed to …
Install Linux Mint 18 KDE from a DVD
On a whim, I tried to install Linux Mint 18 KDE from a DVD instead of USB. Despite a few problems…it worked. Didn’t mess up my grub menu, rendering my computer un-bootable! Want to try out Plasma…KDE 5. I had stability problems in the past, but so far so good. Perhaps this would have worked …
Gmail & PHP
Change Gmail from IMAP to POP3 to save email with Thunderbird. Since I enabled 2-factor yesterday I needed an app password from Google to use on Android phone. Install LAMP and Ubuntu server under VM. In order to test changing my PHP programs that work in version 5.3 but not 5.5. Qualityhost had to bump …
