Lecture 7: Debugging and Profiling (2020)

[@skyeplus]

It's great to have an overview of what options exist, rather than discovering them one by one over the years.

Learning about all these tools and how to work with data in the bash shell has changed the way I use Linux. Thank you guys for putting this up for us to view on KZbin!

Thank you very much for the lecture. As mentioned in the letcure, just knowing that these great tools exist can be helpful when you run into issues.

Amazing lectures, thanks a lot for sharing them! You guys are really helping students all over the globe by sharing with them the knowledge that would otherwise take years of hard work to gather.

I enjoyed seeing the profiling/stress testing after 37:02. Would be cool to make a course like this one that focuses on optimizing or fixing bad code using these tools.

As an experienced SRE, new thing I learned is "lnav". And later, that also took me to another tool "angle-grinder". Both look cool!

6:34 So where does the color.sh come from?

[@jesperolsen98]

#!/usr/bin/env bash for R in $(seq 0 20 255); do for G in $(seq 0 20 255); do for B in $(seq 0 20 255); do printf "\e[38;2;${R};${G};${B}m█\e[0m"; done done done

The python line_profiler profiles real (wall clock) time, right?

[@RaymondWang-f7x]

to be aware of the existence of this type of technology would be helpful.

So did these ask questions after the lecture? Coz it is boring if nobody asks a question.
