#Airisu: The Crow and the Witch
Okiku Part II (Airisu POV): Post 49
#Wss366 Pointer #TimeTravelAuthors What's a lie a character believes about themselves?The path to Himeji Castle descended steeply, and we soon lost sight of the shaman as the mist closed in around her. It was hard to imagine that she was a previous incarnation of my mistress. Their levels of competence were so different. Still, it gave me hope that Sumika would mature. A classy, wise familiar like me needed a fantastic mistress.
We walked to town mostly in silence. At first, I tried to give Sumika some #pointers to help her mature, but stopped after she told me I was being egotistical. Me egotistical? I can’t imagine a more modest crow, but I shut up rather than rekindling her earlier animosity.
In the town, people had begun to stir. I could already hear the ring of an anvil in the distance and the cawing of large-billed crows, nasty things, from the castle’s rooftops. Even without Seirei-onna's warning that they served the castle’s kami, I wouldn’t have wanted to meet them: an event that seemed almost predestined.
Despite the early hour, Sumika drew a crowd. An unaccompanied woman in a gentlewoman’s kimono wasn’t something people here saw often. She was sure to draw the kami’s spies.
I glanced toward the castle’s roof. “Mistress…” I began in warning.
“Shh.”
“Maybe if I fly ahead…”
“I said, hush. I have a plan.”
“A plan? This pigeon brain has a plan? Perhaps I was rubbing off on her!”
“There one is,” she said, turning in at a hut on the town's outskirts.
What did she want there? No one had risen yet, or the occupants had already left for the fields, so she couldn’t have come to request something. Was she planning to hide in the house until evening? That didn’t seem likely. This new turn in Mistress’s behavior had me stumped.
I watched as she picked up an old willow basket, replacing it with a string of coins.
“Please hop in,” she said to me.
“Ack!” I cocked my head and looked at the container. After my reaction to the car, did she think I let her shut me up in that thing? Time had broken its weave in places, and feathers were caught on the snags. I could imagine what it must smell like inside.
“Trust me. It’s for your own good. I’ll let you out as soon as I can.”
The castle wasn’t far. I could fly there and wait, I thought. That was a much more attractive idea than getting into a cramped basket where I might catch some fowl disease. Ack, ack, ack. Even at a moment like this, I was a hilarious comedian.
Basket or castle; that was the question.

Some years ago, I published this project on computing the #Mandelbrot set #fractal in the C #programming language using #pointers and POSIX #threads.
This project is for the JavaScript- or Python-obsessed, high-flying #IT practitioners. The goal is to introduce to the scripting language aficionados the systems programming concepts, specifically programming in a parallel and hardware-proximate manner, with a focus on mathematical computations. There is a comprehensive README, and the code is also fully commented.

👶✨ Ah, the age-old tale of coders valiantly managing #memory with their bare hands (because clearly, malloc and free are for wimps). This riveting yarn spins a tale of complex #syntax and pointers—wait, no pointers!—meant to impress the 3 people who actually understand it. 🧠🔧

🚀 Wow, a whole article to tell us that #Go has an assembler and a #garbage collector! 🎩 Apparently, combining them is as thrilling as watching paint dry, but fear not—our hero is here to walk us through the riveting dance of #pointers and write barriers. 📚✨ Who knew #assembly could be this exciting? Oh wait, nobody. 😴

To react on subject
I never abbreviate functions; I want to read them all so that when I read back the programming code in a month a year or 10 years it still makes sense to me without reading my remarks

Code-Maze author Konstantinos Polychronopoulos writes a good overview of memory pointers in C#, including the caveats, and their limited but still important use cases (mostly having to do with optimizing large array data manipulation and access, and interacting with unmanaged code e.g., C, C++, and others.)

🎩🧐 Behold, the riveting #sequel to 'Memory Management'—as if the first wasn't thrilling enough! Brace yourself as our intrepid author attempts to make #C++ sound like it's not just C with a monocle. 🥱🔧 Spoiler: It's still about #pointers, and no one's impressed.

TIL: C array subscript operators are handled in such a way that `letters[i]` is equivalent to `*(letters + i)` and because addition is commutative, that expression is identical to `*(i + letters)`, which means that `i[letters]` is the same as `letters[i]`.
```
#include <stdio.h>
#include <stddef.h>int main() {
char letters[3] = "abc";
size_t i = 2;
printf("letters: %p\n", (void *)&letters);
printf("i[letters] (%p): %c\n", (void*)&(i[letters]), i[letters]);
printf("letters[i] (%p): %c\n", (void*)&(letters[i]), letters[i]);
return 0;
}
```Which outputs:
```
letters: 0x7ffc68ec7bb9
i[letters] (0x7ffc68ec7bbb): c
letters[i] (0x7ffc68ec7bbb): c
```Mind blown... :neofox_floof_explode:

I'm unraveling an Unreal Engine editor crash bug.
When the crash happened, the editor got confused internally between 2 characters. One has a set of pointers that the other does not.
When the game starts, and it's time to head to work, a vendor instead sprints to (0,0,0), and the log says one of those pointers is missing. It is not. It is missing in the other character because they are of 2 different base classes, and it doesn't have those pointers. That character with the "missing" pointer was once spawned in the game, but not as a vendor. What they have in common is the same skeletal meshes and animation blueprints.
Somewhere, somehow, it thinks both skeletal meshes use the vendor base class. Uh... no.
I saw the confusion when I was deleting the location markers. It showed both characters were using the location marker that it can't find when the game is running. Uh... no again.
About to delete the character it's confused about. Not the vendor. Yet. I may delete both of them and start over. If this breaks it all, well, thank goodness for backups.

Three Libraries for the Python-kings under the ML sky,
Seven for the C++-lords in their halls of hackerone,
Nine for Mortal Frontenders doomed to DROP BY,
One libc on his dark throne;
In the Land of Pointers where the void * lie.
One Library to rule them all, one Library to find them,
One Library to bring them all, and in the pointer arithmetics bind them;
In the Land of Pointers where the void * lie. -

no matter how many docs I read, no matter how many stackoverflow/reddit/whatever posts I read, no matter how many videos I watch to try to understand the concept,
i just cannot fucking grasp the usage of pointers in golang.
i 100% understand what they are (memory addresses) and the benefits of using them (use address where data is instead of copying or passing around all the actual data). but none of that knowledge helps me develop a "muscle memory" for the ways * and & are used when reviewing pull requests or existing code.
I have no prior experience with pointers in any other language, so comparisons to C aren't helpful.
anyone else ever struggle really fucking hard with pointers in golang, no matter how much you "academically" understand what they are? any resources or exercises that might help it "click" for me?
