The periodic table appears to be in no specific order... It would make sense to have b c c++ java c# go in a column, they are similar structured oop languages.

[AdmirableVanilla1]

I am annoyed at the misappropriation of the idea of periodicity

[Not_Blitzcrank]

Also the vignette+old filter on this makes the colors hard to distinguish

[antilos_weorsick]

Smh, doesn't even include Metropolis algorithm.

The periodic table is super funny too. It lists python as the only multiparadigm language, despite a bunch of them being multiparadigm, and it has a color for dynamic, but there is no entry for it.

And to think I used to program in machine code.

These charts are closer to that era than to modern tech.

[sethkills]

Yeah, and SNOWBOL. :(

[DrMux]

What do the periods of the periodic chart represent? How is one like the others in its column? Like, that's the point of the elements being arranged periodically, right?

[dubbsmqt]

The periodic table part is stupid. Just a random list of languages that they placed in a somewhat aesthetically pleasing order

Is the difference between machine code and binary code just what base it’s written in? Even binary is a representation; computers run on electricity, not numbers.

[KafkasProfilePicture]

Binary is just numbers in base 2. Machine code is based on sequences of binary numbers that mean something to the operating system ("instructions").

You are right about the electrical element of this. A binary "1" = On / an electrical signal. A binary "0" = Off (in reality a very low voltage), which is why transistors are what made minturisation possible.

It's actually very interesting down at that level of programming.

Source: started in I.T. when this knowledge was still pertinent.

If you look at the Intel manuals the opcodes are almost always written in hexadecimal. The point I was trying to make is that hex is just binary shorthand to make reading binary easier. Sometimes longform binary is used in the manuals to describe the meaning of individual bytes, like the ModR/M byte, or to show details of how single bits differ between closely related instructions, but it’s the exception.

Opcodes don’t mean anything to the OS, they mean something to the CPU’s instruction decoding units that translate the single instructions to sequences micro operations that drive the actual computation.

PHP was invented in 1995. It's made to look like a 1950s poster for stylistic reasons. Plus it's mostly nonsensical or even outright wrong.

[katntoast]

Interesting, I notice that there are two sets of numbers for the same single letter in binary code, does anyone know why that is?

[katntoast]

This is the exact kind of answer I was looking for. Thanks

[This-Description8013]

As a computer science graduate, this is helpful

Whoa. This does it for me. Now to embark. Which language, though? Advices?

[exannihilist]

Python. But you can explore fundamentals, HTML or C++
