Hello and welcome to the club! It depends on your skill level. For some it can be very difficult an OS, Linux or no.
I'd recommend practicing on a VM first to verify your technical chops.
Step 1: Download virtualbox and create a new Linux virtual machine with 30 GB of disk space.
Step 2: Download a Linux ISO and mount it in the VM.
Step 3: Maximize the VM window and install Linux.
Step 4: Play around with your new Linux installation as though it were your real OS.
Corporate murders happen, but usually overseas, and usually not when they’ve already testified.
Do you have a source for that? I doubt there's graph of "workers murdered by companies, by country" or "murders, pre- vs post- whistleblowing" so it sounds like that might at best an educated guess, or at worst pro-US bias.
The only stats I could find show that historically the US has had a terrible record for worker deaths during labor disputes.
I'm so tired of this freepressjournal trash, it's always some clickbait article that looks like it was written by a child for a middle school book report. Can we stop posting throwaway sources like this and use real sources instead?
