Have you wanted to learn how to program but lacked the support? #100DaysOfCode is a formal (but flexible) process with a clear set of rules designed to motivate you. Part of the process involves sharing your goals and progress via social media and your files via GitHub, which is a free online repository website and version control service which many teachers are now using as an alternative to a traditional website.
Welcome to the first of hopefully a series of “snippets” blog posts. I have to admit I’m poaching the idea from @dougpete with his “My Week Ending” series [example]. My life seems to be too hectic to publish “real” posts so let’s see if this works as an alternative.
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?
