There are three main types of modern acoustic guitar: the classical guitar (Spanish guitar/nylon-string guitar), the steel-string acoustic guitar and the archtop guitar, which is sometimes called a “jazz guitar”.

Electric guitars, introduced in the 1930s, use an amplifier and a loudspeaker. Like acoustic guitars, there are various types of electric guitars including hollowbody guitars, archtop guitars (used in jazz guitar, blues and rockabilly) and solid-body guitars.

Arm Officially Supports Panfrost Open-Source Mali GPU Driver Development

Filed under
OSS

Most GPU drivers found in Arm processors are known to be closed-source making it difficult and time-consuming to fix some of the bugs since everybody needs to rely on the silicon vendor to fix those for them, and they may even decide a particular bug is not important to them, so you’d be out of luck.

So the developer community has long tried to reverse-engineer GPU drivers with projects like Freedreno (Qualcomm Adreno), Etnaviv (Vivante), as well as Lima and Panfrost for Arm Mali GPUs. Several years ago, Arm management was not interested at all collaborating with open-source GPU driver development for Mali GPUs, but as noted by Phoronix, Alyssa Rosenzweig, a graphics software engineer employed by Collabora, explained Panfrost development was now done in partnership with Arm during a talk at the annual X.Org Developers’ Conference (XDC 2020).

Open Up: Open Source Hardware — A Chat with Carl

Interviews
OSS

From a broader lens, to produce “open source hardware” means that we have developed and shared the recipe to create a high-end commercial product that can be learned from, adapted, and used by anyone else. In the same way we’ve stood on the shoulders of the Linux and open source software giants who came before us, we now get to be pioneers in developing open source hardware for those who come next. If you want to learn more how a computer is designed or how something is made, our schematics are the instructions for how to do it. It describes every step of the process, from each piece of the machine and its dimensions, to the type of aluminum used and how to bend it.
It’s similar to open source software in that you can learn from the product, adapt it to your needs, and distribute it. The difference is that it requires outside equipment to produce your own version. Open hardware has become more accessible with 3-D printing, but as we found when we were making acrylic prototypes of Thelio, you reach a point where it’s time to work with metal, which presents its own challenges. You have to cut it, bend it, and paint it, all of which requires specific equipment.

  • Pros and cons of using open source software in your business

    Open source software (OSS) refers to computer software which is released and distributed with its source code open for modification by other users. The source code is released under a license where the copyright holder has granted the rights to use, study, change or distribute the software for any purpose.

    Often developed in a collaborative, public manner, many developers are able to add, change and manipulate the source code to suit their needs.

    Software licensed as open source allows commercial companies to run, modify and share the underlying software code. Open source licenses are legal contracts between the creator and user.

    Although often available to access free of charge, open source licenses sometimes have restrictions applied. Restrictions may mean a user must preserve the name of the original author within the code, or there may be limitations on the way they are allowed to redistribute the software.

    [...]

    Free software has nothing to do with price, rather it is about freedom of use. Free software respects the freedom and community of users, giving the right to run, copy, distribute, change or improve the software. Campaigners for software freedom, Gnu.org, use the analogy “think of “free” as in “free speech”, not as in “free beer”.

    Free software allows users to control the program and what it can do for them. If users don’t have control of a program, this is referred to as “nonfree” or “proprietary”.

  • How the Internet Archive is Ensuring Permanent Access to Open Access Journal Articles

                         

                           

    Researchers found that 176 open access journals have already vanished from their publishers’ website over the past two decades, according to a recent preprint article by Mikael Laakso, Lisa Matthias, and Najko Jahn. These periodicals were from all regions of the world and represented all major disciplines — sciences, humanities and social sciences. There are over 14,000 open access journals indexed by the Directory of Open Access Journals and the paper suggests another 900 of those are inactive and at risk of disappearing. The pre-print has struck a nerve, receiving news coverage in Nature and Science.

Increasing Lab Efficiency with an Open Source LIMS

Filed under
OSS

A Laboratory Information Management System (LIMS) is a software-based laboratory and information management system that provides streamlined workflow automation and management. This type of software is typically used in analytical laboratories such as R&D labs, in-process testing labs and quality assurance labs.

A LIMS seeks to embrace the way you work, offering single sample, batch samples and manual or automated methods, producing reports for internal or external customer use. Management of resources is an important characteristic of planning work allocation against availability and for auto analysers around calibration and maintenance schedules.

IPFire 2.25 - Core Update 149 released

OSS
Security

We have been busy baking another large update for you which is full of oozy goodness. It includes an updated toolchain based on GCC 10 and glibc 2.32 and we have added a lot of tuning which makes IPFire 33% faster on some systems.

IPFire is based on glibc 2.32, the standard library for all C programs, and GCC 10.2, the GNU Compiler Collection. Both bring various bug fixes and improvements.

The most notable change is that we have decided to remove a mitigation Spectre 2 which caused that user space programs in IPFire were running about 50% slower due to using a microcode feature which is called "retpoline". Those "return trampolines" disable the branch prediction engine in out-of-order processors which was considered to help with mitigating leaking any information from any unaccessible kernel space.

Delightful Free and Open Source ASCII Art Tools

Filed under
OSS

ASCII art is a graphic design technique that relies primarily on computers for presentation and consists of pictures put together from characters defined by the ASCII (American Standard Code for Information Interchange) standard. These characters are letters, numbers and special characters such as # / and \. ASCII art is as much a constituent element of the internet as emoticons, cats, or acronyms such as ROTFL and LOL.

ASCII art was invented, in large part, because early printers lacked graphics ability. Characters were used to replace graphic marks. Dot matrix printers designed for bulk printing often used ASCII art to print large banners, to help distinguish different print jobs from different users. ASCII art was also used in early e-mail when images could not be embedded.

Best Free and Open Source Media Centers

Filed under
OSS

The majority of Linux distributions come supplied with a wide range of software that lets individuals use their PC to watch movies and television programs, listen to a music collection, and view photos. However, if you are looking for a more harmonious approach, turning your Linux box into a state of the art media center with an integrated easy-to-use interface, media center software will be just the ticket.

In the media center department, Linux has a fairly narrow range to choose from. Fortunately, the software featured in this article ticks all the boxes. We have also chosen to include some distributions which are dedicated media centers, as they significantly simplify the installation process particularly on esoteric hardware. At the heart of each of these distributions is Kodi.

The 10 Best New Features in GNOME 3.38

Gnome 3.38 is released. This new version with the codename “Orbis” brings along a lot more new features and improvements. This post will look at some of these features that you should expect. Even though this powerful Desktop Environment includes all the features we will look at, their availability may differ from one distribution to another. The downstream packaging process mainly causes that. Some of these features might be renamed, relocated, or omitted for later versions of the particular distro. Since Ubuntu 20.04 is an LTS release, you can’t install the Gnome 3.38 here. If you are in dire need to test this new release, you can download the ISO file for GNOME 3.38 BETA and use it as a virtual machine. Alternatively, you can wait for the release of Ubuntu 20.10 in October as it is meant to ship with this new GNOME release. Read more
