Explaining how computers really work—from logic gates, CPUs, memory, C Language, and Linux to RISC-V, ARM, x86, AI, and large language models.

Dennis Ritchie wasn't trying to create one of the world's most important programming languages. he was trying to build a better language for Unix. Ken Thompson's B was too limited for the new PDP-11, so Ritchie started adding types and building a real compiler. That became C. the first version was built on a machine with just 24 KB of memory. Decades later, C is still running the world.

hey, that's so cool! sounds like a simple yet important part of circuits. 💅

Why is every tech giant hoarding GPUs right now? 🤖💡 It comes down to one core architectural difference: 1️⃣ CPUs prioritize low latency (running sequential logic as fast as possible). 2️⃣ GPUs prioritize high throughput (running thousands of parallel threads at once). Turns out, rendering 3D pixels in video games requires the exact same math as training LLMs. Once you understand the hardware-software boundary, the entire AI stack finally makes sense.

AI safety and proper controls are becoming more important than ever as autonomous agents continue to evolve.

DRAM needs refresh, while NAND traps charge.

Plus it keeps laptops like the @Dell XPS 13 thin, light, cool, and efficient!

How Linux Works youtu.be/9PkIYK9tdAI?si=NU-E… A simple ls command travels through: User ↓ Shell ↓ fork() ↓ execve() ↓ Kernel ↓ VFS ↓ Page Cache ↓ Filesystem ↓ Terminal before you see the result. Most users never realize how much happens behind a single command.

How Linux Architecture Works ? youtu.be/KNw5b8emVpU A simple Linux workflow looks like this: User enters a command in the shell The shell interprets the command System libraries translate requests into system calls The kernel processes the request Device drivers communicate with hardware Results return back to the user application

Copy Fail CVE-2026-31431: How 4 Bytes Turn a Linux User Into Root #kernel #cpu #pagecache #copyfail youtu.be/3cwZV57aiCA Most Linux LPEs need a race window or a kernel-specific offset. Copy Fail is a straight-line logic flaw — it needs neither. The same 732-byte Python script roots every Linux distribution shipped since 2017. Part 1: Why This Vulnerability Is So Special Part 2: The One Concept You Must Understand Part 3: The Critical Insight Part 4: How the Attack Works Part 5: The Bug Itself Part 6: Writing Into the Page Cache Part 7: The Final Step Part 8: Why This Is So Dangerous Part 9: Containers Are Not Safe Part 10: How Did This Even Happen Part 11: Final Insight

Pipeline ≠ Parallelism Pipeline: Same work, overlapped Parallelism: Different work, simultaneous One improves flow. The other increases capacity. #CPU #Hardware

Clear distinction, real outcomes matter. Latency and determinism are big wins for FPGA in AI inference and networking, curious about toolchains

Google just dropped a quantum bomb 💥 Their new chip Willow solved a problem in <5 minutes That would take a supercomputer 10 septillion years Now people are asking: Are quantum computers tapping into parallel universes? Reality: No proof of that. But something big is happening. ⚡ #QuantumComputing #Google #AI #Tech

Now here’s the twist for hardware people: This is software pretending to be hardware. JavaScript → CPU → Linux If you’re into FPGA, flip the stack: Hardware → CPU → Linux Same architecture. Completely different performance.
BREAKING: Someone just ran a full Linux system… inside a PDF file. No VM. No install. Just open it in your browser. It’s called LinuxPDF.

Why ARM still exists in FPGA systems: Because FPGA is terrible at: •Control logic •OS-level tasks •Dynamic decision making So we pair them. This is why SoCs exist.

The 2026 Integrated Circuit (IC) landscape just shifted. 🏗️📐 We’ve officially hit the "Advanced Packaging" era. It’s no longer about how small you can make one chip; it’s about how many "chiplets" you can stack like LEGOs without melting the board. The monopoly of monolithic silicon is dead. If your design isn't modular, 3D-stacked, and AI-accelerated, you’re shipping a paperweight. The new arms race isn't in the code. It’s in the gates. ⚡️ #IntegratedCircuits #Semiconductors #Chiplets #Tech2026 #Innovation

If you think the AI revolution is powered by magic, you’re wrong. It’s powered by 4AM debugging sessions, supply chain miracles, and the absolute chaos of trying to keep a 700W GPU from turning into a space heater. 🌡️ We’re not just building chips anymore; we’re building the brain of the planet. #NVIDIA #AI #Semiconductor #BigIoT #Chips

ARM is the new IBM. Reliable, sure. But the innovation is happening in the RISC-V trenches. The shift is already over; the big players just haven't realized they're obsolete yet.

You don’t really understand a CPU… until you build one yourself. Here’s how a CPU actually works — using FPGA 🧵👇
