1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of “discuss” rarely comply with this rule.

2. Original, Fresh, Meaningful Content.

3. Avoid repetitive topics.

4. This isn't an advice forum

Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.

There are a number of content specific communities with subject matter experts who can help you.

Some other communities to consider before posting:

5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.

6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.

7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with “So” - starting a post with pointless phrases, like “I hope this is allowed” or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

Just as little experiment, as a part of a larger journey to try to understand how computers work, I started to learn the programming language C on my free time. I have only ever studied Japanese, linguistics and didactics... For a few months now, I have been able to make a program that prints various stuff on the screen using the commonly known function printf. This, of course, didn't satisfy me at all, since this doesn't tell me how the displaying of characters on my screen is actually happening. To make a somewhat forced comparison, I'm using a toaster to toast a slice of bread, but I have no idea how the heating strings inside the toaster become hot. In order to understand "the toaster", I tried to dig up a piece of the source code responsible for making "my bread crispy and delicious". Well...

Can something be DISHEARTENING and fun at the same time?

This is basically a study in layers of abstraction.

At the very fundamental layer you just have a semi-conductor... Special sand that can either allow electricity to pass, or block electricity...

Then when you arrange multiple of these semi conductors in special ways, you get logic gates.

When you arrange the logic gates in special ways you can make more complex operations that can essentially do math with the electric signals.

Then you introduce even more of there bits to be able to perform many different instructions, and some form of memory that can store instructions and execute then in sequence.

With the right set of instructions you now have what is know as a "Turing machine". Essentially a super basic computer that understands machine code.

You extend the list of instructions and, and you arrive at Assembly.

Then you decide to make a simpler more human readable language and write the assembly to translate this language to Assembly, this is basically C with a compiler.

Then you start building languages with higher and higher levels of abstraction to make them easier for humans to express their intentions with.

If you want to start at the very bottom layer and try to build some of those abstraction layers yourself to understand what's going on. I can warmly recommend trying out https://www.nandgame.com/

Come to think of it... Even the semi-conductor layer is an abstraction on top electricity, and electricity in turn is an abstraction on top of electron movements...
