- update and upgrade
  installed Arduino IDE 1.8.19 from manager (don't know what happened to previously installed version...)
- Currently running Linux Mint 21 Vanessa

- Glitching continues, but different now. Several times in the last week, when running FC, the tower will, without warning or any pre-symptoms, reset itself.
  It happens in a moment, instantly, without usual boot-up delay.
  All apps close, password box comes up on desktop.

- Glitching has continued, less when I have fewer spreadsheet files open. However there have been twice that everything shut down, power, all dead. It restored OK.
- Preparing to download some mp3 apps. Closed all, did update/upgrade.
- $ sudo apt install ffmpeg
  successful
  $ ffprobe ...mp3 worked, but on ...wav it did not give any info, though it did not error...
- $ sudo apt-get install lltag eyed3 mp3info id3v2 libimage-exiftool-perl libid3-tools id3tool

- Screen lockup weirdness has persisted. Over time I've come to believe that it has to do with my video card, because it happens when I have multiple screens on, especially if I'm using FreeCAD, which is surely compute-intensive anyway.
- In any case, I also know my computer room has inches of dust on the floor, and I'm thinking dust on computer chips that get hot will make them hotter and more prone to getting weird, so I bit the bullet and pulled the tower out and opened up and vacuumed and blew out everything I could.
- Disturbing that when I first put it back together and turned on the power, nothing came on. Took the side panel off again, put it back on, and this time it worked. Either there's a lock-out on the side panel that I missed the first time, or perhaps the power cord just wasn't plugged in all the way the first time. In any case, it's booted up now, and first try with FC had no screen glitchiness, so we'll see how it goes the next few days/weeks.

- Lost track of details/timing, but at this time, I am successfully running Linux Mint 20.3 Una
- That said, I am still getting occasional video weirdness, only rarely locking up, but I often shut down and cold reboot to clear the problem.
  Currently researching an upgraded graphics card...

2021-08-02 - 03
- Tower has been shut down for months now. I suspect I got a virus, as it was acting strangely. Have decided to ditch Windows-10 completely and just do Linux.
- Cleaned up files, moved everything I want saved into myWorkingFiles - total ...GB
- Backup up all to sanDisk-tb1.
- My intention now is to do a fresh install of latest Linux Mint, which is 20.2 Uma
- Downloaded iso, now struggling with verifying ...

Beginning the process of installing kiCAD:
forums suggest installing from PPA for latest version
Software Manager currently has version: 4.0.7+dfsg1-1ubuntu2
However per notes ...here... , I will instead install directly from current version in Software Manager
$ sudo apt-get update
$ sudo apt-get dist-upgrade
in Software Manager, select Kicad, click Install, Continue, enter password...
Installed successfully, however did not create a desktop icon. To launch:
- $ cd /usr/bin
  $ ./kicad
- -OR-
  open Software manager, search for kicad
  click Launch

Was having trouble getting Arduino Teensy working with the Arduino IDE 1.8.7 that I had on this machine, so I installed the latest version, 1.8.11. See here for procedure. All worked successfully.

And this morning, trying to log on to mysql in terminal with:
$ sudo mysql -u jay -p
while it did ask me for a password, and I tried 3 different ones (linux, ttt, linux) but then got locked out and now I can't even get in with:
$ sudo mysql -u root
However after stopping and re-starting mysql,
$ sudo mysql -u root
again worked to get into mysql, and without asking for a password, and
$ sudo mysql -u root -p ... did ask for a password, but accepted [CR]
At this time config file is set to: AllowNoPassword=TRUE and auth_type='cookie'
Weird. With no other changes since it worked, this time
$ sudo mysql -u root -p ... asked for "[sudo] password for jay:" but accepted linux login password,
then asked for "Enter password:" and accepted [CR]
Removed phpmyadmin via Software Manager, then:
$ sudo apt-get update
$ sudo apt dist-upgrade
then install again, then launch
browser window comes up. selected localhost,
username: root; password: neither root, nor linux login worked
from forum:
$ sudo dpkg-reconfigure phpmyadmin
(link to:) askUbuntu - 892513
(link to:) askUbuntu - 763336
(link to:) stackOverflow

did a bunch of stuff and it finally worked. See phpmyadmin page for details...
But now I have "No privileges" to create a db in phpmyadmin as needed to set up a drupal db.
forum says: edit /etc/phpmyadmin/config.inc.php and change auth_type from 'cookie' to 'config',
however this bombed with a page of errors when I tried to access localhost/phpmyadmin

Hacked around trying again to reset mysql root password. This time tried
$ mysql_secure_installation ... y to most prompts except the first for secure password plugin
all seemed successful, with new password "tttt", however I could still log in to mysql with just a [CR], and I could Not log into localhost/phpmyadmin with user root & new password tttt.

from: (link to:) linuxize.com
$ sudo mysql -u root
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '3xt';
mysql> FLUSH PRIVILEGES;
... and while it seemed to work:

[CR]

instructions then say to stop and restart mysql:
$ mysqladmin -u root -p shutdown ... however when prompted, new (3xt) password did not work
Instead I stopped it with: $ sudo service mysql stop, and restarted with: $ service mysql start, but no effect.
tried again (Try This Again...) per: (link to:) bakerstreetSystems.com
error.log issue see: (link to:) support.plesk.com
Go Figure: Not even sure what all I did, but again logged into phpmyadmin at localhost, and lo, this time I could create a db.
Proceed with Drupal: Local Server Installation...

Lots of unsuccessful hacking:
used forum procedures to try to change mysql password, however can't tell if it worked. That is, when I log on with:
$ sudo mysql -u root -p, while it does ask for a password, it accepts anything, the new password I put in, or a simple [CR] that was apparently the default password.
Tried various edits of /etc/phpmyadmin/config.inc.php, doing true or false on both lines of 'allowNoPassword', to no effect.
Edits of /etc/phpmyadmin/config.inc.php to change 'auth_type' from default 'cookie' to 'http' locked up the browser when localhost/phpmyadmin was loaded.
After most of these edits, I stopped and re-started the mysql program, and a couple of times did a complete cold boot.
Some forum notes say to directly enter your changed password into config file in the line:
$cfg['Servers'][$i]['password'] = '[yourNewPassword]';
However my version of phpMyAdmin does not have that line, apparently having changed to putting the password somewhere else (into cookies?) for security reasons.

Proceeding to install a Drupal local server.
It appears that (necessary component) Apache was installed with mySQL last month.
There is a /var/www/html directory, and entering "localhost" into URL of browser brings up Apache welcome page.
However it appears that PHP (another component necessary for Drupal) is not at this time installed.
See Drupal Blog for more details...
Installing PHP:
$ sudo apt update
$ sudo apt dist-upgrade
$ sudo apt install php7.2-cli
$ sudo apt install hhvm
restarted...
phpinfo confirmed install was successful.
Installed mysql-client from software manager
Installed phpMyAdmin Version 4:4.6.6-5 from software manager
