9 Best Free and Open Source Command-Line Image Compression Tools

Filed under
Software
OSS

Data compression is the process of storing data in a format that uses less space than the original representation would use. Compressing data can be very useful particularly in the field of communications as it enables devices to transmit or store data in fewer bits. Besides reducing transmission bandwidth, compression increases the amount of information that can be stored on a hard disk drive or other storage device.

There are 2 main types of compression. Lossy compression is a data encoding method which reduces a file by discarding certain information. When the file is uncompressed, not all of the original information will be recovered. Lossy compression is typically used to compress video, audio and images, as well as internet telephony. The fact that information is lost during compression will often be unnoticeable to most users. Lossy compression techniques are used in all DVDs, Blu-ray discs, and most multimedia available on the internet.

Top 5 Open-Source eLearning Platforms for Linux

  • Top 5 Open-Source eLearning Platforms for Linux

    The world of education, like other sectors, has been undergoing the process of digital transformation for years. With the creation of e-learning platforms, education is now available to anyone who has access to the Internet. The term “e-learning“, which means “electronic learning“, is one of the most commonly used words today. It refers to training and education typically on the Internet.

    Modern e-learning platforms or LMS (Learning Management System) are based on a virtual learning space that, in general, is oriented to simplify the distance training experience. So, due to the importance that e-learning has, it is necessary to know which are some of the best platforms available.

    In this post, you will find a brief overview of 5 open-source solutions for e-learning that can be installed on a Linux machine.

Review: Auxtral 3

At the beginning of this review I mentioned Auxtral reminded me of Linux Mint Debian Edition. The theme, the Cinnamon desktop, and general look of the project certainly held that first impression. However, the default applications and tools (apart from the Cinnamon desktop and command line utilities) felt quite a bit different. Linux Mint has been around for several years and has earned a reputation for being beginner friendly, polished, and shipping with a lot of top-notch open source applications. Auxtral appears to have a similar approach - similar base distribution, the same desktop environments, and a similar look. However, Auxtral does have its own personality under the surface. It ships with a quite different collection of applications, sometimes using less popular items (Brave in place of Firefox, SMPlayer instead of VLC, etc.) It has also gone its own way with software updates, preferring classic tools like APT and Synaptic over Mint's update manager. Auxtral is off to a good start. This was my first time trying the distribution and the experience was mostly positive. The operating system is easy to install, offers multiple desktop environments, and walks a pretty good line between hand holding and staying out of the way. The application menu is uncluttered while including enough programs to be useful. Some of those programs are a bit more obscure or less beginner friendly than what you might find in Linux Mint, but otherwise it's a good collection. Virtually everything worked and worked smoothly. I was unpleasantly surprised by this distribution's memory usage, most projects consume about half as much RAM, but otherwise I liked what Auxtral had to offer. I might not recommended it to complete beginners, especially since the project does not appear to have any documentation or support options of its own, but for someone who doesn't mind a little command line work or who likes the idea of an easy to setup distribution that combines Debian with the Cinnamon (or Xfce desktop) this seems like a good option.
