A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted, clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts: 1

All posts must be showerthoughts
The entire showerthought must be in the title
No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- If you feel strongly that you want politics back, please volunteer as a mod.

If "Master/Slave" terminology in computing sounds bad now, why not change it to "Dom/Sub"? (lemmy.dbzer0.com)

It sounds way less offensive to those who decry the original terminology's problematic roots but still keeps its meaning intact.

I think I could argue that master/slave doesn't describe that functionality. Does the master drive control the slave drive?

I think a better example is the SPI bus, which has a one-controller-many-peripherals bus topology with two data lines often referred to as MOSI and MISO: Master Out Slave In and Master In Slave Out. (in addition to a clock line and one or more chip enable lines) In this case the controller does literally control the peripherals, which aren't allowed to put data on the bus unless commanded to. Newer documentation is using the terms COPI and CIPO, for Controller Out Peripheral In and Controller In Peripheral Out. Personally I prefer MOSI and MISO because there's a definite way to pronounce them; how do you pronounce "CIPO?" See-poh? But it's something for someone somewhere to be uppity about so sure let's expand the glossary.

The activity light on the Master drive will light up in sync with the Slave drive when accessing data on just the Slave drive. At the end of the IDE lifespan, there was a movement to put the names as Primary and Secondary instead. It doesn't really describe the relation to how the hardware works, though.

I mean that does actually work better. If there's only one, it has to be the Primary. If there's two, one of them has to be the Primary and the other one is the Secondary. That makes more sense to me. Because neither drive is sending the commands here, the IDE controller either built into the motherboard or on an expansion card is sending the commands, that's the "master."
