Webserver rebuild after failed uprade

I updated my webserver with Ubuntu 18.  Then I decided to upgrade to Ubuntu 19.  But first I needed a backup of WordPress.  I decided on “UpdraftPlus“.  I backed up my WordPress data and moved it to a thumb drive.  Then for the move to Ubuntu 19.  It failed.  After about 1.5 hours the process just hung.  I did a hard reset and that was it.  I should also point out that I had no power to the PC internals – MB, disks so I am assuming that shortly after I started the upgrade the Power supply failed.  Can’t complain:  10 years x 24 hours a day.  Took me 4 days to rebuild the box.  I had good Readme.files but many of the commands in them were no longer valid because mysql, apache2 had changed their syntax for their commands/statements.  Lots of Googling.  Anyway once I got the box configured  to support WordPress and got WP downloaded and installed I once again downloaded the UpdraftPlus plugin for backups/restore.  I moved the backup files from the thumb drive to the newly build PC and using UpdraftPlus restored the data.  PERFECT!!!  About 2 minutes and my WordPress blog was recovered vs. 4 days of rebuilding a PC.  UpdraftPlus is definitely a winner.

Ubuntu Server install on a Pi 4 – easier then you might think

Like many of us waiting for a version of Ubuntu Mate for the Pi 4  I kept looking to see if it was released yet.  No.  Nothing.  However in my search I came across a website that offered promised but when I burned their iso image to the sdc card it failed to boot.  The I came across a Youtube video that got me passed the “failed to boot” issue so that I could login.  There would still be hurdles to come but I present the procedure here in what I hope will be an almost cut and paste procedure.

PTZ not working in Blue Iris 5 with Yoosee camera

I recently received a new PTZ  camera (works with the Yoosee video application)  I ordered the camera from AliExpress. I got the video side working fairly easily with the Blue Iris camera app, but had some real difficulty getting the camera to pan/tilt/zoom. In an associated page I will show you what I did. It is quite easy actually.  You can read the details  here .

bought a new “cruncher”: AMD RYZEN 1700 and AMD RADEON RX 580

Yesterday I bought a new “cruncher”:  a Dell AMD Ryzen 7 1700 with an AMD Radeon RX 580.  As soon as I got home I removed Windows 10 and installed Ubuntu 16 (tried 17 on this node but had issues).  This PC required the installation of new AMD GPU PRO driver support because Einstein@Home did not recognize the onboard GPU.  There were errors in the AMD procedure which I will address later in a more detailed page on this website.  Now for the “bad news”  Once the drivers were successfully installed Einstein@Home is reporting the GPU as being a 480 and not a 580.  I will have to look into this and depending on what I find contact the store to see what is going on.
