simdvis now visualises PINSR* instructions.
Screenshot of an interactive Intel instruction visualizer for VPINSRB. It shows the syntax VPINSRB xmm1, xmm2, r32, imm8 and explains that one byte from src2 is inserted into a selected byte position of src1. In the example, imm8 = 0x02, so byte index 2 is selected. src1 contains bytes 0xA0 through 0xAF, while src2[0] is 0x1F. The destination row highlights byte 2 changing from 0xA2 to 0x1F; all other destination bytes remain unchanged. A bit diagram at the bottom shows the low four immediate bits as 0010, corresponding to selection index 2. https://serpent7776.github.io/simdvis/pinsr.html#vpinsrb

Techno Kitty #screenshotSaturday
Pixel-art bullet hell screenshot with a synthwave look: a striped orange sunset sits over a glowing magenta grid on a starry night sky. An orange tabby cat sits low in the middle of the screen inside a bubble shield, with a small grey kitten drone on one side and a purple one on the other, firing a fan of five shots upward. Up near the sunset, the boss, a spiky red-and-green starburst inside red aura rings, fires a big ring of pink hearts. Cyan, red and yellow bullets fill the rest of the screen. The HUD reads "TRACK 5/5 NINE LIVES" and lists the active upgrades: Laser Whiskers, Kitten Drones, Glitch Step, Catnip Shield. Five heart lives are shown in the top right.

🐱💜 Techno Kitty <3 Bullet Hell is out!

Pixel the tabby has to out-dance D.J. Heartbreak, a virus living in Neo-Mew City's giant AI subwoofer.

5 remixes from 165 to 185 BPM, where every bullet and laser fires on the beat.🎶

A pixel-art orange tabby dodges a storm of glowing cyan, yellow and heart-shaped bullets over a neon synthwave grid and sunset. "ON THE ONE! x13 +6500" flashes above her.

current PHP drama according to grok
Cartoon meme split into two scenes. Top: Cool, smiling PHP elephant mascot in a purple beanie and sunglasses lounges on a cloud next to a glowing Earth labeled “70% of the Web,” under the text “PHP FOR 20+ YEARS:”. Bottom: The same Earth is on fire with exploding servers and browser error messages (500, 503, 502, 404). Panicked developers run around screaming “NOOOO!!!”, “NOT PHP2SHELL!!”, and “WE’RE DOOMED!”. A terrified, sweating PHP elephant wears a seashell on its head and covers its face in horror. A casual black penguin sips from a mug reading “NOT MY PROBLEM / CHAINGUARD”. Bottom caption: “AI FINDS PHP2SHELL:”.

HotSpot #JVM stack layout explaining yellow/red/shadow zones and stack banging.
Diagram of a HotSpot JVM thread stack growing downward. Below the active frames and the stack pointer is a shadow zone, then free stack, then the reserved, yellow and red guard zones at the low end. A "stack bang" arrow shows a method writing to stack pointer minus the shadow size when it is entered.

#Lua is somewhat weird when it comes to returning multiple values.
Finally, a statement like return f() returns all values returned by f: function foo (i) if i == 0 then return foo0() elseif i == 1 then return foo1() elseif i == 2 then return foo2() end end print(foo(1)) --> a print(foo(2)) --> a b print(foo(0)) -- (no results) print(foo(3)) -- (no results) You can force a call to return exactly one result by enclosing it in an extra pair of parentheses: print((foo0())) --> nil print((foo1())) --> a print((foo2())) --> a https://www.lua.org/pil/5.1.html

You can setup alternate signal stack with SA_ONSTACK
SA_ONSTACK Call the signal handler on an alternate signal stack provided by sigaltstack(2). If an alternate stack is not available, the default stack will be used. This flag is meaningful only when establishing a signal handler. https://www.man7.org/linux/man-pages/man2/sigaction.2.html

English is so fun
"James while John had had had had had had had had had had had a better effect on the teacher" is a nearly grammatically correct English sentence used to demonstrate lexical ambiguity and the necessity of punctuation,[1] which can also mark the intonation,[2] stress, and pauses found in speech.[3] In human information processing research, the sentence has been used to show how readers depend on punctuation to give sentences meaning, especially in the context of scanning across lines of text.[4] The sentence is sometimes presented as a puzzle, where the solver must add the punctuation. https://en.wikipedia.org/wiki/James_while_John_had_had_had_had_had_had_had_had_had_had_had_a_better_effect_on_the_teacher

Wasmer engine, module, store, instance explained.
Wasmer 7 diagram. WAT source with a global counter and functions bump and get is compiled by an Engine into one shared copy of machine code and a Module. A Store from the same engine holds two instances of that module, A with the counter at 3 and B at 0. Each instance has its own vmctx (globals, memory, tables) but points at the same engine code, shown by a dashed line labeled "one copy, shared". Handles a, b and Function values point into the store. Notes: a Function is code pointer plus vmctx pointer, calls need &mut store, dropping a handle or the engine frees nothing, dropping the store frees both instances.

slotmap data structure
Screenshot from Allan Deutsch’s “The Slot Map Data Structure” presentation at C++Now 2017. The slide, titled “How it Works: Overview,” shows a diagram of a slot map data structure with arrays of indices and data slots connected by red arrows, alongside free-list pointers, capacity, size, and erase information.

So apparently #bash can do network calls without any extra utilities. No idea why would you put this into your shell.
/dev/tcp and /dev/udp Syntax in Bash /dev/tcp/HOST/PORT and /dev/udp/HOST/PORT are not real filesystem paths. Bash intercepts these paths at the shell level and opens a socket to the given host and port instead. They work with exec redirects, </> operators, and read/write commands — but only in Bash, not in sh, dash, or zsh. https://www.commandinline.com/bash-network-programming-dev-tcp-connections/

@crertel I didn't do anything. I asked two frontier agents to make the most of Elixir and this is what they came up with. Please do send a PR to speed things up! But also realize that it's not exactly extra points for Elixir if frontier agents can't find the magic "go fast" switches.
