Hard Reboot
Googling inevitably reveals that my problem is caused by a known bug triggered by doing [the exact combination of things I want to do]. I can fix it, or wait a few years until I don't want that combination of things anymore, using the kitchen timer until then.
Title text: Googling inevitably reveals that my problem is caused by a known bug triggered by doing [the exact combination of things I want to do]. I can fix it, or wait a few years until I don't want that combination of things anymore, using the kitchen timer until then.

Explanation

This comic is about using a simple and unrelated trick to fix a problem.

Swap space is a reserved area of a computer's hard drive reserved for use when the computer runs out of RAM. Ideally, RAM + SWAP >= MAX, where MAX is the amount of RAM the computer is expected to ever reach.

It would take up to 10 hours to figure out why the server is running out of swap space and fix the problem. Alternatively, Randall could just take 5 minutes and plug the server into a light timer.

Using the timer would make it experience downtime every day, but it would be predictable, and schedules can be fit around the 5 minutes. Also, it can be scheduled during, say, the middle of the night when most users are sleeping to minimize disruption.

The correct method of scheduling a regular reboot would be using a CRON task. Of course, the problem could be solved without a reboot simply by increasing the swap size.

The title text's first sentence refers to situations where the given solution to a problem is just the original problem rephrased to sound like a solution. It may also refer to bug trackers, where someone found out and posted what causes the issue, but the bug is marked as "Unresolved," "Waiting," or "Will not fix."

The title text's second sentence is about the human tendency to wait on someone else to fix a problem rather than doing it yourself. Since everyone is waiting on someone else to do it, such problems tend to never be fixed, hence the solution of "wait[ing] a few years until I don't want that combination of things anymore."

Transcript

A section of a screen with a white-on-black color scheme is shown. The screen is covered in lines of illegible text.

Figuring out why my home server keeps running out of swap space and crashing: 1-10 hours

Next to the section of the screen is a timer plugged into a power port with cable running off to the side.

Plugging it into a light timer so it reboots every 24 hours: 5 minutes

Why everything I have is broken
