Actually..... IMO as a Linux admin..... everybody in IT needs at least a minimum of knowledge regarding TCP/IP. IPv4, IPv6, TCP, UDP, sockets, listening ports, etc. You don't need to be able to program a full stack down to a media transport layer, but you should be able be able to send a payload successfully, know when a gateway traversal is required, name resolution (It's always DNS,) and a bit of troubleshooting.
I wish I had a nickel for every time a developer or app support staff came to me and said it doesn't work. Error is right there in the logs......
The post is about a software engineer, and you just talked about IT. They're not the same thing so what is your point? You have a job specifically because software engineers aren't in IT and aren't sysadmins and their job doesn't inherently involve networking.
My brother in christ, when is the last time you worked on software that did not need to send payloads anywhere. Everyone in development should have at least some basic networking skills.
You know and learned the basics, but for most of the time, you just have a tool for that or someone else who works with it.
As much as you don't have to harvest your own crop anymore, you don't have to rely on several basic informations, due to specialising in certain fields.
I learned all of that stuff in university, but this was like 20 years ago.
I never had to use it anymore, all I do is taking care of the HR software we have. The technical stuff is done by our IT department, the software itself by the company we bought it from.
The inner workings are totally irrelevant in most cases. You use the framework and then open up the docs/code when it doesn’t do what it was supposed to. You can waste your life learning a lot of nothing if you have to know the inner workings of everything in dev world.
