Ep2: Working on logger for Nusku
Since we are using Zig and the available libraries and packages are limited, we need to implement some of the core infrastructure code that we need…
What Actually Happens Between malloc() and Physical RAM: Virtual Memory, Page Faults, and the MMU
When you call malloc(100 * 1024 * 1024) in C, new byte[100 * 1024 * 1024] in C#, or allocate a massive buffer in Node.js or Go, how much physical RA…
From a shop-owner interview to an ERP configuration
A software setup wizard often asks the wrong questions. "Enable inventory?" is hard to answer if the owner knows only that items sometimes run out b…
How to Validate FFI Between QM and ASIL-D in Zero-Heap AUTOSAR + HSM
Expert Breakdown: Validating Freedom from Interference (FFI) between QM and ASIL-D Architecture: Classic AUTOSAR R22-11, zero-heap design with stati…
ASIL-D Zero-Heap RTOS: 8.7µs CAN-FD Latency with MPU FFI on HIL
Verifying No Interference in the AUTOSAR Base Without Memory for Electric Vehicles For a long time, I've been working on a challenge faced by many i…
How I Built a Pure-Dart SSTP & PPP VPN Client From Scratch (Linux, Windows, macOS)
Most developers use Dart and Flutter exclusively for UI development. But recently, I wanted to see how far I could push Dart's capabilities down int…
Sometimes the Fastest System Is the One Willing to Stop
There is a particular kind of meeting every engineer eventually attends. A metric is projected onto a screen. It has moved in the wrong direction. S…
Automatic Error Recovery in AI Agent Networks
In a single-agent system, failure is simple: the agent errors, you retry. In multi-agent systems, failure is a graph problem. The Cascade Failure Pr…
Willpower is manual memory management — here's why I switched to garbage collection for my habits
I ran out of cognitive RAM three times. Each time, the same crash: I'd commit to a behavior, execute it for a few weeks, then watch it degrade as ot…
BIO Baochip/Dabao - FIFO and Events
FIFO The BIO has 4 FIFOs mapped to the BIO processors as x16-x19 r/w registers (blocking on read until new data is pushed), and in the host through…

What Linux actually does when you read a file
I asked Linux for one 4 KiB page from the start of a cold file. Four pages came back. I moved the same read one page further in, ran it again, and g…
How a 176 KB C Binary Runs a 2.78-Trillion-Parameter Model on One CPU with 8 GB of RAM
The Problem Moonshot AI's Kimi K3 has 2.78 trillion parameters. Stored naively at bfloat16, that's 5,560 GB — more than the combined memory of two f…

I compile C to a 468-byte ROM that runs identically on x86 and ARM
I run a mesh of agents on old phones. They check invariants — is a watchdog's lease longer than twice its producer's cadence? Is the battery in its…
You don't understand a system until you've rebuilt it
