(NB: adapted from this Ask Ubuntu thread -- tested to work on Ubuntu 16.04 LTS through Ubuntu 22.04 LTS (Jammy).

Unlike using VMWare Tools to enable Linux guest capabilities, the open-vm-tools package doesn't auto-mount shared VMWare folders. This can be frustrating in various ways, but there's an easy fix.

TL;DR

Install open-vm-tools and run:

sudo mount -t fuse.vmhgfs-fuse .host:/ /mnt/hgfs -o allow_other

Adjusting child processes for PHP-FPM (Nginx)

When setting these options consider the following:

• How long is your average request?
• What is the maximum number of simultaneous visitors the site(s) get?
• How much memory on average does each child process consume?

Determine if the max_children limit has been reached.

• sudo grep max_children /var/log/php?.?-fpm.log.1 /var/log/php?.?-fpm.log

Be Careful with Table Driven Tests and t.Parallel()

We Gophers, love table-driven-tests, it makes our unittesting structured, and makes it easy to add different test cases with ease.

Let’s create our table driven test, for convenience, I chose to use t.Log as the test function. Notice that we don't have any assertion in this test, it is not needed to for the demonstration.

func TestTLog(t *testing.T) {
	t.Parallel()

There are plenty of one line terminal commands that can prove to be exorbitantly dangerous.

1. The Delete Everything Command

    rm -rf /

This command deletes everything it possibly can, including files on your hard drive and files on connected removable media devices. This command can be explained as follows:

    rm – Remove the following files.
    -rf – Run rm recursively.
