Re: How can I get the latest version of MariaDB?

Wow, my question seems to have generated quite a "tempest in a teapot". I actually have Buster running on a different Pi, but it is having difficulty running some of my programs and finding drivers for a few of my HAT devices. Thus, I'm reluctant to move to Buster for this application. Can MariaDB b...

Seeing SAMBA shared in Windows 10 Network display

Historically, most likely before version Windows 10 1903, when I clicked the Network link in the "This PC" item in the File Explorer, it would show all of my Samba Pi shares as well as all of the other computers on my network. Now I only see the computers on my network. I can map to these Pi shares ...

How can I get the latest version of MariaDB?

About a week ago I installed MariaDB via sudo apt-get install mariadb-server and it is all working just fine. However, I just tried to use the ROW_NUMBER() function and MariaDB throws a syntax error. Further investigation ( https://mariadb.com/kb/en/library/row_number/ ) seems to indicate the this f...

Solved: Problem running a CRON job

The Mystery deepens or maybe clears up!!! Sometimes it is amazing how sleeping on a problem will lead to a solution. In this case sleeping had nothing to do with it, it was the passage of time that mattered. OK, I think that my earlier assumption, that CROM was misbehaving, is correct. This morning ...

Re: Problem running a CRON job

Yeh, that is basically the command I reported above except I was piping the output to a file on my USB stick. Regardless, when I pointed it to output.txt (actually /home/me/output.txt) it worked. GRRRR So now, I back to trying to figure out the issue with my sendtome.sh script. I can't spend any mor...

Re: Problem running a CRON job

PCMANBOB....Thanks for your reply, but I'm beginning to think there is something more fundamental going on here, maybe my CRON service is not running or is misbehaving. To test this idea I entered the following into my cron -e : 39 14 * * * /bin/ls > /mnt/usbdrive/output/CRON_output.txt 2>&1 I got n...

I'm running Stretch on a Pi v3, recently updated.

Re: Client email to send emails from command line

Sheer stupidity!!! When I created this new Gmail account, I mistyped the userid. A subtle error, an 'n' instead of a 'r' in the middle, so it was not obvious. Thus in my config file I had the wrong Gmail authorized user name. Seems to be working now... Thanks for your time....RDK

Re: Retrieving MySQL data from Windows Excel

OK, thanks for your efforts. This is not a critical issue. My workaround is to run an app on the Pi to retrieve the data to a CSV file and then import it into Excell. That works but adds an extra step. Not a big deal. However, if I can get the direct access approach to work, ever better….RDK
