A Checklist for Learning

08/12/24 • 3 min

One of the challenges many people have is focusing their learning efforts along some path. The best way to move forward is with steady effort that guides you through steps to build knowledge or skill. However, with so much information out there on the Internet, how do you decide where you focus your efforts?

Lots of people choose a random method, but the world is full of those people, many of whom never develop strong skills. That might be fine if you are an hobby guitarist or piano player, but it's not the best way to approach your career.

Send Metrics Not Logs

This is part of a series on observability, a concept taking hold in modern software engineering.

One of the interesting things I saw in an engineering presentation on Observability from Chik-Fil-A was that they are sometimes bandwidth-constrained at remote sites. In an early version of their platform, they sent logs back to HQ, and their logs used all the available bandwidth, so they were unable to process credit card transactions.

While most of us don't deal with lots of remote offices sending data back to a central data warehouse, we do often work in distributed environments, and we may send data to/from a cloud or even employees' remote offices. Or maybe we send a lot of data between components. Bandwidth is very good in many parts of the world, but it isn't infinite.

Prevent Complete SQL Injection

I would hope most of you reading this know what SQL Injection (SQi) is and how you can prevent it. Or at least what patterns cause problems. If not, here's a short explanation that is worth reading. If you have more questions, ask in our forums.

SQL Injection has been, and continues to be, a problem in many systems. In fact, I chatted with Mike Walsh recently after he'd published this post on an attack for one of his clients. He has some notes that explain how your database server might be vulnerable, as well as a description of a recent attack example. He also notes that many of you are responsible for protecting data, which is separate from other security mechanisms. You need to be sure you are protecting your data, even in vendor applications.
