The time between getting a new piece of hardware and seeing a first shell prompt can be one of the most frustrating experiences for embedded Linux developers. Buildroot can help reduce your frustration. more>>
It is summer on the northern hemisphere, and I've decided to target a smaller system than I've been used to in the last couple of years. In particular, I've decided to finally open my dear old PICkit II. The goal is to be able to work with this board from within a Linux environment. more>>
Booting a computer is always more complex than one wants to think. On the PC side, it looks as if BIOS finally is retired and replaced by EFI (I wonder which was the last OS to use BIOS for anything that just loading a secondary bootloader). On Mac, EFI has been around for a while. On embedded Linux systems, however, u-boot has been a big player for a long time. more>>
GUI debuggers are the norm these days, however, I still feel the urge to do a little printf-debugging now and then. It might be wrong, it might be silly but it works.
I like to develop the odd graphical application and I like use Qt. For Qt, the nice Norwegian Trolls have provided the qDebug function. You can use it right away just like your old trusted printf: more>>
On of the great aspects of Qt is that it is cross platform. Not only across desktops, but also across devices. The Qt make tool, qmake, can be configured to cross compile for different architectures using different compilers and different settings. How to do all this is reasonably straight forward, but you need to know how to get started. more>>
Qt 4.7 has not been released yet, but the curious can download the beta or even grab a snapshot from git. The big news in this point seven release is Qt Quick - a new approach to user interfaces. more>>
Sys-V init has long been the standard solution for booting. It's kind of easy to work with, it kind of works and everybody kind of knows it. However, being open minded, let's look at an alternative approach. more>>
What is your strategy on cross compilation toolchains? Here we explore a
few options: more>>
DIY - requires you to manually start each step, unless you're comfortable enough to script the process. As each step takes ages, this can be a tedious job. However, it gives you full control and insight into each step.
As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.
Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.
In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
