As a Python programmer and teacher, I’m always on the hunt for good tutorials. Some of the best Python tutorials I found are on a YouTube channel named Socratica. For these videos they have a McGill CS graduate & actress named Ulka Simone Mohanty [@ulkaM | resume] whose character is a quirky, robot-like narrator with a very dry sense of humour, which for me, makes the videos especially entertaining.
In my YouTube subscription alerts I saw that Socratica has just released some new videos related to SQL databases. If they’re as good as their Python series I had to check them out.
It was nice to see that they are also using Ulka to narrate this series. And it’s nice to see that the videos are just as entertaining (and informative) as the Python series.
I have some experience programming in MySQL (thanks to Dr Chuck) so was really interested in its popularity vs PostgreSQL and MariaDB. The video is only an overview, but it’s enough to whet my appetite about revisiting my old My SQL programs and seeing how difficult they are to convert to the other formats. It also gets me thinking about investigating free accounts in the cloud for any databases I write.
I’d love to hear what you think about these videos. Do you find them as entertaining and informative as I do?

“The Art of Listening is a documentary film about the journey music takes to reach a listener’s ear, from the intent of an instrument maker and composer, to the producers and engineers who capture and preserve an artist’s voice. This journey is narrated by intimate conversations with artists, engineers and producers about the philosophy of their work and the intent behind each musical note they create.
This film is an invitation for music fans to rediscover the intricacies and details available in the sounds of their favorite recordings. The Art of Listening is the beginning of a conversation of how the quality of our listening experiences define the medium.”
Harsh words. I can’t dispute whether flickering lights are truly bad for our health, but it should be fairly easy to quantify the varying qualities of LED lamps by the amount they flicker1.
This would make for an interesting project at school. In my Computer Tech class, for instance, we could build a simple circuit with a light sensor and then display it on an oscilloscope (yes, I still use one!) or sample it into a computer at a high enough rate to measure the flicker rate.
Anyone else up to the challenge?
1 I keep wanting to type “flickr”. It’s the photographer in me trying to get out…
After applying an update to my UnRAID server a message popped up telling me that I didn’t have system notifications turned on.
I popped into Settings > Notifications Settings only to have discovered that I didn’t have any notifications turned on. Well, that’s not good.
In the SMTP Settings sections Gmail was already listed, so this should be easy. Nope, it never passed the test. A quick search helped me find this forum where it showed me the proper SMTP settings for Gmail:
An App password is a 16-digit passcode that gives an app or device permission to access your Google Account. If you use 2-Step-Verification and are seeing a “password incorrect” error when trying to access your Google Account, an App password may solve the problem. Most of the time, you’ll only have to enter an App password once per app or device, so don’t worry about memorizing it.
I had never heard of this before, but it was the solution I was looking for. The service generated a simple 16 digit password that allowed me to send notification emails using my Gmail account.
This process only has to be done one time, and the password is never used anywhere else (I assume it’s locked to the sending device) so I don’t have to remember it.
