# My wish that I can't see

There's fire outside. The world is collapsing, it's over. It's not going to be just fine; it's never going to be. I sing nothing. This is not of mine. $$\sin\theta \sec\theta$$ is all I have, even though, all I need is 1. It just is.

When the world is dark,
Nothing seems so stark,
End is all that I don't see,
All I can do is flee.

What do I see?

I can see no program, I only see code. I see no year, only the digits remain. I see no country, only land is. I see no word, only the letters remain. What has gotten into my eyes? What is happening? I got a message that would've given me my dream but I can't see it, I only see {{99, 111, 116, 120579}, 4}

Give me my wish... Use the message that I couldn't see and give me my wish.

• I changed your $sin$ and $sec$ to $\sin$ and $\sec$. Not sure whether the original was intended - please roll back if that's the case. I guess changing to $\tan \theta$ would ruin the wordplay. Jan 5, 2022 at 15:03
• @WhatsUp I didn't know $\sin$ and similar things existed. If I say anymore, I'll spoil it so... And, I'm confused whether the wordplay tag should be present. It's vague, this whole site is vague. What is wordplay even defined as? This puzzle contains vague no "wordplay" in the classical sense but there is wordplay and if I explain how, I'll spoil it. Even though making it into $\tan$ wouldn't be detrimental, it won't matter because it's not a maths problem, it's just that you need to have some math capabilities. I've chosen the specific trig so that it's more thrilling. Jan 5, 2022 at 16:06

Solution:

An HCF/halt-and-catch-fire instruction.

Process below.

The message is

$$\cot{\theta}$$

Reasoning:

The final "4" is a dead giveaway that it's a Unicode-formatted text stream, since 0x4 is the end of file character. The preceding set consists of 99 -> 0x63 -> "c", 111 -> 0x6F -> "o", 116 -> 0x74 -> "t", 120579 -> 0x1D703 -> mathematical symbol italicized lowercase $$\theta$$.

Therefore what you lack is

Encoding. The examples provided all refer to unprocessed data: uncompiled code, a date without a calendar standard to make it mean something, coordinates without a GIS database, a string without a dictionary, the raw input $$\cot{\theta}$$ without Unicode encoding, and the value $$\tan{\theta}$$ without multiplication by $$\cot{\theta}$$ to cancel it out.

Thus,

Given the references to fire, the world just ceasing to exist, and the cessation of output,

You have seen

A halt-and-catch-fire instruction, a term for an instruction that when executed completely and unrecoverably stops the CPU from doing anything useful,

And to see your dream you need

To reboot the system.

Edit: To make this a complete solution I determined a reading of the poem that works with this context.

"When the world is dark":

"Dark" in the sense of "provides no signal," since nothing can execute.

"Nothing seems so stark":

One possible meaning of "stark" is "rigid," like a system that is completely unchanging due to having run Halt and Catch Fire.

"End is all that I don't see":

The program never halted, it's just hanging indefinitely.

"All I can do is flee":

On the original halt-and-catch-fire instruction, the unrecoverable cessation of function was due to the instruction pointer constantly incrementing without being able to process the code at that memory address. Thus, you (the instruction pointer) are constantly fleeing from the code you're supposed to be running.

• You slightly misinterpreted {{99, 111, 116, 120579}, 4}. You're so close. It has additional info about how the hcf was caused. Great work though. Jan 29, 2022 at 4:47
