6. Bash and PowerShell: Sure, more modern devops tools are handy, but sooner or later something isn’t going to work and it won’t have quite what you need. So, expect to need to know how to write a basic restart script, grab an error code from an exiting command, or do a few things in a loop. That’s what Bash (in Linux, many Unixes, MacOS, and Windows 10) and Microsoft’s PowerShell let you do. Bonus: Add a tool like Grep (PowerShell’s equivalent Select-String is more wordy) and you’ll be an even more powerful deity.
7. MongoDB: You need to know how to work with at least one document database. MongoDB is the easiest to learn. Whether you’re ultimately going to use MongoDB isn’t relevant; what matters is learning how to deal with a new-generation database. If you’re going to use an index like Apache Solr, which is document-shaped, or you’re going to work with a more columnar structured database, the MongoDB skills will transfer.
8. Curl and Invoke-RestMethod: Most software now has a REST API. On Mac and Linux, Curl is the command-line tool that lets you test and tweak and even script against a REST API. In PowerShell, it is Invoke-RestMethod (although like everything on PowerShell, it requires more typing). There are GUI tools like Postman that accomplish the same work, but a serious developer needs to be able to move past a point-and-click interface for efficiency’s sake.
9. Markdown: This is the format of the README.md file in GitHub. You should be able to read and write a simple Markdown document. And that’s easy because it has just seven symbols: (# is a header, ## is a subheader, * is a bullet, __ and ** are bold, _ and * are italics, ` is monospace, and — is a break or rule). Markdown editors often have extensions but those are the basics. From that basic markup language, you can get slides, PDFs, and HTML. Often these output formats can be consistently formatted with CSS or some other way. Best of all, you don’t end up with smart quotes in your code samples.
10. Basic HTML: I can’t make a decent-looking web page to save my life; I’m a back-end developer. But whether you’re going to stub something out or have to parse HTML, you will need to know basics of the web markup language.
