Best Photo Editors for Linux

This article will cover a list of free and open-source image editors available for Linux. These applications feature basic tools for simple editing needs as well as advanced utilities for professional artists. GIMP If you are a regular Linux user, chances are that you must have heard about GIMP (GNU Image Manipulation Program) or used it to edit images. It is considered to be one of the most comprehensive, free, and open source image editing software available not only on Linux, but also on other operating systems like Windows and macOS. While some users may prefer proprietary tools like Photoshop over it, GIMP itself is packed with tons of features and can do almost everything that Photoshop is capable of. You can see all major features of GIMP available at here and here. GIMP can be extended using plugins, some of them come with the official installation while others can be downloaded from third party websites. [...] RawTherapee RawTherapee is an open source image editing software specially designed for processing and handling “raw” images. You can also import and edit image files having other formats. RawTherapee features various utilities for processing raw images including color enhancement tools, compositing and masking utilities, pixel correction tools and HDR utilities. Read more

5 Best Free and Open source NAS Software for Linux

In the 21st century, huge innovations have been made in various sectors, particularly the technological region, which has completely changed the world’s dimensions. The strides at which new technology has been developed and improved upon from its predecessors would surely be something that our ancestors would marvel at. Humans have gone in a very short time from making stone arrows and straw huts to developing smartphones and automated robots, and these advancements are continuously growing without slowing down. However, this huge transition has also brought forward some adverse effects as our machines are now subjected to more cyber-attacks and security issues. Data is one of the most important factors in the world today, and it is exactly that which is the most vulnerable. Therefore, it is necessary to implement procedures that would help in keeping your data secure. One excellent way is to use NAS software, which helps in keeping backups of your data. This shall also be the topic of our discussion in this article, where we will be looking at the top 5 free and open-source NAS software available on Linux. Read more

Pioneer DDJ-RR DJ Controller To Be Supported By The Linux 5.11 Kernel

For aspiring DJs wanting to mix beats under Linux, the Pioneer DJ DDJ-RR controller should be working come Linux 5.11 early next year. The Pioneer DDJ-RR is quite a capable ~$699 USD DJ controller that offers the mixing potential of many higher-end Pioneer DDJ devices but at a lower price point and geared for introductory DJs. The DDJ-RR is a two-channel controller and offers all of the common dedicated controls most DJs would make use of while offering high quality audio output. The DDJ-RR is designed to be used under Windows with the Rekordbox DJ software. However, this DJ controller will now work with Linux 5.11+ so it can be used with software like the open-source Mixxx DJ software package. Read more

Release notes for the Genode OS Framework 20.11

With Genode 20.11, we focused on the scalability of real-world application workloads, and nurtured Genode's support for 64-bit ARM hardware. We thereby follow the overarching goal to run highly sophisticated Genode-based systems on devices of various form factors. When speaking of real-world workloads, we acknowledge that we cannot always know the exact behavior of applications. The system must deal gracefully with many unknowns: The roles and CPU intensity of threads, the interplay of application code with I/O, memory-pressure situations, or the sudden fragility of otherwise very useful code. The worst case must always be anticipated. In traditional operating systems, this implies that the OS kernel needs to be aware of certain behavioral patterns of the applications, and has to take decisions based on heuristics. Think of CPU scheduling, load balancing among CPU cores, driving power-saving features of the hardware, memory swapping, caching, and responding to near-fatal situations like OOM. Genode allows us to move such complex heuristics outside the kernel into dedicated components. Our new CPU balancer described in Section CPU-load balancing is a living poster child of our approach. With this optional component, a part of a Genode system can be subjected to a CPU-load balancing policy of arbitrary complexity without affecting the quality of service of unrelated components, and without polluting the OS kernel with complexity. A second aspect of real-world workloads is that they are usually not designed for Genode. To accommodate the wealth of time tested applications, we need to bridge the massive gap between APIs of olde (think of POSIX) and Genode's clean-slate interfaces. Section Streamlined ioctl handling in the C runtime / VFS shows how the current release leverages our novel VFS concept for the emulation of traditional ioctl-based interfaces. So useful existing applications come to live without compromising the architectural benefits of Genode. Platform-wise, the new release continues our mission to host Genode-based systems such as Sculpt OS on 64-bit ARM hardware. This work entails intensive development of device drivers and the overall driver architecture. Section Sculpt OS on 64-bit ARM hardware (i.MX8 EVK) reports on the achievement of bringing Sculpt to 64-bit i.MX8 hardware. This line of work goes almost hand in hand with the improvements of our custom virtual machine monitor for ARM as outlined in Section Multicore virtualization on ARM.
