The distinction is meaningless in the land of Opcode’s and memory addresses
For example, a struct is just an imaginary “overlay” on top of a contiguous section of memory
Say you have a struct
struct Thing {
int a;
int b;
Thing* child;
}
Thing foo {}
You could easily get a reference to foo->child->b by doing pointer arithmetic
*((*((*foo) + size(int)*2)) +size(int))
(I’ve not used C much so I’ve probably got the syntax wrong)
Mostly because at the lowest level of computing (machine code and CPU instructions), pointers are the only method (that I know of) of any kind of indirection.
At the lowest level, there are 2 types of references:
Every higher level language feature for memory management (references, objects, safe pointers, garbage collection, etc) is just an abstraction over raw pointers
Pointers themselves are really just abstractions over raw integers, whose sole purpose is to index into RAM
With that in mind, pointers to pointers are a natural consequence of any kind of nested object hierarchy (linked lists, trees, objects with references to other objects, etc)
The only other kind of indirection would be self-modifying machine code (like a Wheeler Jump). But the computing world at large has nixed that idea for a multitude of reasons
The composition is incredible. I wonder how this was taken, or if it’s one of those hyper realistic drawings
It doesn’t look AI generated
Edit: the reflection of the rope holding the swing doesn’t match. The reflection is quite straight and clean compared to the reflection of the wood supports. Odd
Oh, so that’s what all of you are talking about.
I still don’t really see what all the fuss is about
Shell scripts don’t count
That’s not a programming language, that’s hieroglyphs
Exactly, that’s why you write down ideas immediately, when you have them
I have obsidian set to dump new notes into an “Inbox” folder
If i have an idea, i jot it down in a new note (usually from my phone), and move on
Then i can later catalog it properly
Don’t brainstorm
Collect ideas as you think of them throughout your day. Then when you need to “brainstorm”, read through your ideas and references

Most of the time, it’s me
Even medicated, it’s impossible for me to keep a normal sleep schedule
I think of it as compensation for waking up at noon every day

I’ve never really had good ideas to post
Even on reddit
We kinda do, with GPS satellites that have to correct their clocks due to the effects of gravity and speed
And communication with space probes
I use 24h clocks and ISO 8601 dates almost always
Honestly, I’m better at organizing code than I am my actual life
Timezones make intuitive sense for humans
UTC / Unix timestamps make intuitive sense for computers
The issue is bridging the gap
I am a programmer, and i also like the naming scheme on the right
Especially for things like filenames
It’s an explicit “opt-out” by the OP, such that their content cannot (legally) be used to train LLMs or such (Chat GPT, Github Copilot, etc)
Well, that’s what I assumed until i read the license terms. It doesn’t explicitly mention AI or LLMs, but it does say
You may not use the material for commercial purposes
Which i assume has the same limitations for AI training, for commercial AI

The thumbnail is a shot of kde plasma, not w11
While i also disagree with python’s tendency to use exceptions as control flow
Python is a pretty stellar scripting language. I wouldn’t use it for app dev, but it’s quite handy for the odd automation or CLI task
I’m more talking about theory than practical.
I’ve not developed anything in C/C++, so I don’t know practical uses for a double pointer, aside from multidimensional arrays, or arrays of pointers
My point was that, conceptually, pointers to pointers is how most complex data structures work. Even if the C representation of said code doesn’t have a
int**somewhere
