A Linux cron job is a scheduled task that runs automatically at specified intervals using the cron daemon, perfect for automating repetitive tasks like backups, updates, or scripts Here is the basic overview of #Linux cron jobs showing crontab format and cron job examples 😎👇

A logic question for you.

If you are curious about logic and would like to study it for yourself, there is a free PDF download by Prof. Harris Kwong on Discrete Math lectures. I just printed sections on logic and set theory and bound it together into a workbook.

Physicists: the formula works for the first seven values, it must be true! Meanwhile, mathematicians:

I should study instead of making memes #grade

"Duality" is a deep concept in mathematics, but an intuitive way to think about it is in terms of tables. When we lay out data in a table, we are familiar with the idea that each row represents a different "entity", and each column represents a different "property". (1/10)

what is a Pringle to a mathematician?

Back to basics math: don't forget to memorize your multiplication tables!

Enrico Fermi completed his doctorate thesis in one month because he was a very fast and efficient worker, and he had already done most of the research and experiments beforehand. He chose to study X-ray diffraction, which is the scattering of X-rays by the atoms in a crystal,

Random spirographs. Made with #python, #matplotlib and #numpy.

A few months ago, I was recommended Hubbard's Vector calculus/linear algebra book ,and I got to say that I vastly prefer this text from any that I had used in the past, when dealing with vector calculus. Very beginner friendly and modern, complete, great for physics students.

I struggled with git until I learned these 17 commands: 1 git add ↳ It lets you add changes from the working directory into the staging area 2 git commit ↳ It lets you save a snapshot of currently staged changes in the local repository, with a message 3 git push ↳ It lets
