Custom Embedded Linux Distributions

The proliferation of inexpensive IoT boards means the time has come to gain control not only of applications but also the entire software platform. So, how do you build a custom distribution with cross-compiled applications targeted for a specific purpose? As Michael J. Hammel explains here, it's not as hard as you might think. more>>

diff -u: What's New in Kernel Development

The OOM killer is a tough nut to crack. How can a system recover when it's violently thrashing and out of RAM? Once upon a time, you'd just have to reboot. And today, that still might be necessary, but less so, because the OOM killer attempts to identify and stop the process that seems to be causing the hangup. The problem is, it may not choose the right process every time. more>>

diff -u: What's New in Kernel Development

There's an ongoing impulse among a diversity of developers to be able to compile some or all of the Linux kernel as a library, so that a piece of software could use kernel services and APIs while running under a different kernel entirely, or a different operating system. more>>
