  • If you’re not already, use it as your main system. Don’t dual boot. Stop using windows and mac. When you run into something you need to do, figure out how to do it on linux. It will be slow going at first, but after a few months you will pick up more productivity than you had before.

    Another commenter recommended the fish shell, but I disagree because fish is not posix compliant. Almost all of the shell script examples that you will find assume posix compatibility and will usually have to be modified to run with fish. Once you get comfortable with a posix-compliant shell, then maybe consider fish or another “modern” shell.

    On the topic of shells, read the bash manual. It’s long and informative. You don’t have to memorize it, but be aware of the different concepts there, and refer to it when you need to. It’s pretty horrible as a programming language, but it’s what glues most of Linux together.




  • Very similar to if you were to send a traditional paper letter in an envelope with a stamp, and put an incorrect return address on it. You could even make it look exactly like something the real company would have sent. There is no validation of the return address. If the recipient were to respond to the return address, it would expose the ruse. The scam is that the contents of the letter have further instructions that lead to the scam.

    Another complication is that the From address in internet email contains an address part and a description part. The address part is what is actually used to route the email, and the description part can be anything, including something that looks like an email address that doesn’t match the one in the address part. Most email clients only show the description part and hide the address part.

    For example:

    From: “Bob Smith” <bob@example.com>

    From: “robert@somewhere.com” <bob@example.com>

    From: “Do not reply” <noreply@example.com>

    From: “quickbooks@notification.intuit.com” <scam@attacker.com>

    Edit: formatting
