PHP/SQLite3 form pre-populated does not update database when hitting submit

Situation: On a web page, the end user is asked to provde a database id. They enter the database id, hit submit, and a pre-populated form appears where they can edit any parts of the record that they need to. They then hit submit and, theoretically, the form updates the SQLite3 database and displays the […]

Master-slave flip flop without gate delay?

It seems like a master-slave flipflop always has around a 2-gate delay between the Master and Slave sections of the flip flop. For example: My question is what would happen if, theoretically, there was a zero-delay between the Master and Slave sections of the flip flop? Would the master/slave relationship still work properly, or is […]

Ways to study mathematics.

Recently, I read about a post from a postdoc in mathematics called “Yin Li” who is active in a famous forum called “Zhihu” in China before. He mentioned that as long as we do every single exercise and have a firm understanding in Mathematical Analysis, Linear Algebra, Abstract Algebra and Topology, theoretically, we do not […]

Why can neural networks generalize at all?

Neural networks are incredibly good at learning functions. We know by the universal approximation theorem that, theoretically, they can take the form of almost any function – and in practice, they seem particularly apt at learning the right parameters. However, something we often have to combat when training neural networks is overtfitting – reproducing the […]

Move docker images without using `docker`

I have a Docker host that became unreachable for me. The only thing I could get was snapshots of its volumes. I need to extract the docker images from those snapshots. I created regular volumes from the snapshots, which I was able to attach to a new virtual machine. I now have access to the […]

If a programming language does not support method overriding then what inconveniences the programmer might face?

Theoretically, Child class can’t override parent class’ methods if needed. But How does it actually affect in practical aspect? What issues the programmer will face?
