Editor's Note: Embedded Linux has consistently ranked among the top operating systems used in embedded system design. With the rapid growth in interest in the Internet of Things (IoT), the ability of ...

Editor's Note: Linux remains an attractive option for embedded systems developers. In fact, industry surveys such as the Embedded Market Study by UBM (EDN's parent company) consistently show interest ...

Have you ever felt the urge to make your own private binary format for use in Linux? Perhaps you have looked at creating the smallest possible binary when compiling a project, and felt disgusted with ...

this IRC conversation on my page should be instructive (I am "rindolf" there). Essentially, even an elegant dinky "log analyser" that people showed me how to write properly using ghc segfaulted. And I ...

Kernel modules are chunks of code that are loaded and unloaded into the kernel as needed, thus extending the functionality of the kernel without requiring a reboot. In fact, unless users inquire about ...

So all I need to reuse your GPL software is to make it into a library (still under the GPL) and link to it. I can use as much of its functionality as I want, engrain it as deeply as I like, but as ...

Blacklisting modules prevents them from being loaded and used, and it is sometimes an important step in keeping a system running properly. The Linux kernel is modular — composed of modules that work ...

To Linux system admins and developers, the extended Berkeley packet filter, or eBPF, can feel almost like magic. With eBPF, IT pros can do something that, until recently, seemed unimaginable: deploy ...
