If ‘apt update’ on Ubuntu 18.04 throws an error N: Skipping acquire of configured file ‘nginx/binary-i386/Packages’ as repository ‘http://nginx.org/packages/ubuntu bionic InRelease’ doesn’t support architecture ‘i386’, then replace the one line of text in /etc/apt/sources.list.d/nginx.list with this line instead.

Writing and calling functions is a key component of the Don’t Repeat Yourself (DRY) principle of software development. Creating a function in a single script and calling that function from other scripts is preferable to performing copypasta of the same bit of code throughout several scripts. When a function lives in a single script, it only needs to be updated in that one place when it inevitably needs updating.
If you wanted to drop traffic at your Linux host destined for, let’s say, IPv6 netblock 2a09:8700:1::/48, you could get that done with this command.
sudo ip -6 route add blackhole 2a09:8700:1::/48
An ‘r’ before a string tells the Python interpreter to treat backslashes as a literal (raw) character. Normally, Python uses backslashes as escape characters.
I was a guest on the February 22, 2022 episode of the So You Wanna Be In IT podcast. I chatted with hosts Pat & Dean about how my career got started. Along the way, we discussed whether or not someone can have a successful IT career without a college degree. Put another way, are IT certifications good enough? I think that yes, you can have a successful IT career without a degree, but that the question, “College degree. Yes or no?” deserves more analysis than a simple yes or no answer offers. Give the episode a listen for more nuance.
PyCharm allows for the passing of environment variables from the IDE to a script, whether that script is running locally or in a remote SSH deployment you’ve configured for your project. To set the environment variables, select Edit Configurations from the Run menu.
Why does adding a query parameter on the end of a curl request against an API endpoint result in an error? Because you need -G and -d, that’s why.
After a several minutes of answering her scripted questions, I lost it. I unloaded on this kid. I was yelling over the speakerphone at her. In an open office. With my boss standing next to me. In front of my co-workers and the junior network engineer I was mentoring, all of whom had either also been there all night or come in early to help with testing. In front of everyone else, I just leveled this poor JTAC girl.
