rapidtables | Super fast list of dicts to pre-formatted tables conversion | Parser library

I'm trying to render the output of a linux shell command in HTML. For example, systemctl status mysql looks like this in my terminal:

As I understand from Floz'z Misc I was expecting that the underlying character stream would contain control codes. But looking at it in say hexyl (systemctl status mysql | hexyl) I can't see any codes:

Looking near the bottom on lines 080 and 090 where the text "Active: failed" is displayed, I was hoping to find some control sequences to change the color to red. While not necessarily ascii, I used some ascii tables to help me:

• looking at the second lot of 8 characters on line 090 where the letters ive: fa are displayed, I find:
• 69 = i
• 76 = v
• 65 = e
• 3a = :
• 20 = space
• 66 = f
• 61 = a
• 69 = i

There are no bytes for control sequences.

I wondered if hexyl is choosing not to display them so I wrote a Java program which outputs the raw bytes after executing the process as a bash script and the results are the same - no control sequences.

The Java is roughly:

I am trying to get the bytes and pointers and how they are stored can any one explain or answer some of my questions. Thank you

i am stucked with 2's compliment about how its works. i am making a number converter same like https://www.rapidtables.com/convert/number/hex-to-decimal.html i have added all the conversions except this 2's compliment. also this conversion is in all hexadecimal to decimal, decimal to binary conversion, decimal to hexadecimal conversions. i don't understand these conversions very well so a explaned answer is highly appericiated.

below is the functions which i use in another js file, but this code missing 2's compliment. i have no idea on how do i calculate it. i want the same functionality like this https://www.rapidtables.com/convert/number/hex-to-decimal.html

Looking at this page https://www.asciitable.com I see that the 254 symbol is a filled square (■). But here: https://www.ascii-code.com it says it's the small letter thorn (þ).

When using the symbol in code as 0xFE on a Mac using the Swift language I get the thorn letter (þ), then how do I get the square (■) in ascii?

Using this tool https://www.rapidtables.com/convert/number/ascii-to-hex.html and (■) as input I get a number larger than 255, so it can't be represented in ascii then?

I have same raw message encrypted using different public e with same public n, so I wanted to use common modulus attack but cant see to get original message. My program is

So i use a custom color from https://www.rapidtables.com/convert/color/hex-to-rgb.html for button title in cell. But somehow some colors are not set like the silver color RGB((192,192,192), it just show white color for the cell button label.

I set button title color using the following syntax:

So, I need to add https://www.rapidtables.com/tools/notepad.html in my website and I need to remove the header of their website. Is there any way?

I'm trying to convert a string with special characters from ASCII to Hex using python, but it doesn't seem that I'm getting the correct value, noting that it works just fine whenever I try to convert a string that has no special characters. So basically here is what I'm doing:

I have been dealing with an issue with MATLAB when trying to visualize the binary representation of large integers and it has really confused me. I am working on a little-endian machine and positive int64 values. Therefore, the most significant bit (MSB) is always 0. All the other bits can be 0 or 1. I noticed that when I check the binary structure of large values many bits on the least significant bits (LSB) side are 0. For instance:
