Until here, I've talked about the embedded Linux development in four stage: toolchain, bootloader, Linux kernel, rootfs. In this tutorial, I will create a SD card image including these and then run it in BeagleBone Black. Firstly, let's remember tha...

I decided I am going to create 1 desktop app a day for the new Ubuntu release because noone ships linux. It's crazy they expect us to dev in linux but ship for windows and mac but you know what ? I am tired of bouncing back and forth! Linux for this...

In this tutorial, I will go with the fourth stage of embedded Linux development which is the rootfs. Every Linux-based system have a filesystem. If you are on GNU/Linux, you already probably know it and how it structured. Apart from that embedded L...

React Native Android builds can fail for a lot of reasons—but one of the most common and confusing ones is: Could not resolve dependency If you’ve seen this, you probably also noticed: the error message is long it looks very “Gradle-heavy” and...

In this tutorial, I'll go with the third stage of embedded Linux development. That's the Linux kernel. It's the responsible for: Manage all the hardware resources: CPU, memory, I/O. Provide a set of portable, architecture and hardware independent ...

In this tutorial, I will continue the embedded Linux development series with second stage which is the bootloader. Firstly, a bit theoretical background. The bootloader is a piece of code responsible for: Basic hardware initialization Loading of ...

Deploying a file server sounds simple. Making it production-ready is where most developers struggle. You don’t just need to run the app. You need to: keep it running secure it handle traffic properly In this guide, you’ll deploy a real file ser...

In today, I'm beginning a new series about embedded Linux development. I'll show that how to build an end-to-end embedded Linux system from scratch by hand. I'll fetch the associated every stuffs from source code and then build the corresponding out...

1. The Execution Chasm Companies invest millions in planning software and ERPs. They spend months integrating data, cleaning records, and tuning demand forecasts. Yet, at the end of the day, execution often relies on an analyst staring at a dashboa...

> Your AI agent crashes after 2 minutes of work. You lose everything. It doesn't have to be this way. I've seen it happen in every production AI project. You build a beautiful agent. It works perfectly in local. You ship it. Then it runs for 90 s...

POSIX shared memory allows to us to share a mapped region between unrelated processes without needing to create a corresponding file. Linux uses a dedicated tmpfs file system mounted under the directory /dev/shm. This file system has kernel persist...

Let's continue discussing the Linux programming with mmap system call. The mmap system call creates a new memory mapping in the calling process's virtual address space. There are two types of mapping: File mapping: A file mapping maps a region of a...
