> Usually this isn’t necessary and its better to just return the error unwrapped.
This is a terrible advice. Wrapping is extremely helpful in providing additional context for the error travelling up the call stack. Without wrapping, one typically ends up with software logging generic errors like "file not found" , which you can't act on because... you don't know where it's coming from. If you skip error wrapping, better be ready to enjoy quality time when production crashes.
I believe the idea is that 'panic' is considered something fatal. If it happens, the application should die unless you have a strong reason for it not to. If you can recover e.g. by returning HTTP 500 for a single request, it should be handled by returning errors up throughout the call stack, i.e., by error handling instead of panicking.
> There's a reason why most FAANGs developed their own packages management and deployment system and keep using them. They are simpler, less bloated, easier to debug.
Most FAANGs developed their computing infrastructure before Kubernetes gained popularity. After all the investment into building it and fine tuning for their software services (like ads), they probably have a lot more reasons to not migrate to something different. Not just because their systems are "simpler, less bloated, easier to debug".
It doesn't work like this. If there is a hiring freeze in place, it means that internal headcounts are also limited. The "desperate team elsewhere" must have money to pay for the new engineer.
It is not harder, it is different. They just ask more system topics, while focusing less on coding. There is, however, a catch. If you get hired as a SRE-SWE, you can easily switch to a regular SWE. If you get hired as a SRE-SE, you may have to reinterview to change your job ladder. SE is okay, but you clearly have more possibilities as a SWE.
Counterpoint: I have a HomePod mini in one of my rooms and it reacts easily to any mention of Siri in other rooms. So I am actually impressed with how good it is in reacting.
