Raspberry PI computer boards are famous for learning to code and small electronics projects. By using the beards as is, you will need cabling and buying the needed sensors. CrowPI2 gives a different way of thinking about Raspberry PI with an innovative laboratory layout
The CrowPi2 is a device which appears, at a first look, as classic netbooks, that were small and very cheap notebooks spreading the computer market in 2010.
The Linux world is incredibly diverse, but it started with a few major Linux distros. Here’s who they are!
There are currently hundreds of active Linux distros, but only a few of them can be described as the mothers and fathers of everything else we know these days as Linux.
They are the ones who have laid the foundation that almost every single Linux distro today stands on. Loved by some or disliked by others, they are the shoulders on which the modern Linux world has stood to get where it is today.
This article will focus on each of them, giving them all the respect they deserve. They are all distros created from scratch, making them one of the so-called original Linux distros, ones that are not based on anything before them.
We had a good week in the world of Linux releases, with Voyager 22.04.1, SparkyLinux 6.3, and Nitrux 20220503.
People who love home theater PC are constantly getting interested in Linux since Microsoft made a wall above the Windows Media Center Edition for the users. As an open source operating system, Linux provides more opportunities to create and maintain a home theater PC. But you will need a Linux Media Server software or distro for that. It can help you to set up a cost and resource-effective media server, which ultimately lets you watch, share, or listen to all the media files from a remote location on your Smartphone or desktop.
My personal music player on Linux is MPD + NCMPCPP but if you want a more contained solution then how about you try out musikcube which even has an android app to control it.
So 5.18 is looking like it's going to be one of the larger releases in numbers of commits (we'll see where it ends up - it's going to be neck-and-neck with 5.14 right now, but won't be as big as 5.13 was). But despite the merge window being big, the release candidates have generally been quite modest in size, and rc6 continues that trend. I keep expecting the other shoe to drop, but 5.18 just seems to be quite well-behaved.
Let's see if this jinxes it, but nothing looks particularly scary here. rc6 looks to be mostly some driver updates (network drivers and rdma stand out, small random fixes elsewhere), with the usual smattering of architecture updates (x86 kvm fixes, but also a long-standing x86 kernel FP use issue, and a smattering of parisc and powerpc fixes). And some wireguard selftest updates.
The rest is mostly some btrfs fixes, some core networking, and just random small one-offs elsewhere.
Please do go test it all out - because things may look good now, but continued testing is the only thing that will make sure.
Thanks, Linus
Miguel Ojeda, author of the Rust-for-Linux, proposed the release of v6 components for Rust device driver development for Linux kernel developers to consider. This is the seventh edition of the patches, taking into account the first version, published without a version number. Rust support is considered experimental, but is already included in the linux-next branch and mature enough to start working on creating abstraction layers over kernel subsystems, as well as writing drivers and modules. The development is funded by Google and the ISRG (Internet Security Research Group), which is the founder of the Let’s Encrypt project and promotes HTTPS and the development of technologies to increase the security of the Internet.

Follow the steps of this tutorial to install the Podman container tool on Ubuntu 22.04 LTS Jammy JellyFish Linux for creating virtual containers.
Podman is a container tool for virtualizing applications. It was originally developed by Red Hat and originated in the Cri-O project, which develops a lightweight container runtime environment for Kubernetes as an alternative to the Docker runtime environment.
It is compatible with Docker on the command line however doesn’t rely on the Docker daemon. Hence, we can use its Container Engine to provide containers without root access. Buildah is the Image builder used by Podman.
Today we are looking at how to install Eclipse IDE on a Chromebook. Please follow the video/audio guide as a tutorial where we explain the process step by step and use the commands below.
In this video, we are looking at how to install Inkscape on Debian 11.
When you go to find a GUI tool to manage your Docker containers, you’ll find more options than you can imagine. Those tools range from the overly simplistic to the remarkably complicated, and everything in between. Every so often, however, you’ll find a desktop client that does an outstanding job of making container management much easier.

In this tutorial, we will show you how to install PostgreSQL on Ubuntu 22.04 LTS. For those of you who didn’t know, PostgreSQL is a popular and powerful open-source relational database management system that has been adopted for running mission-critical applications. It supports a large part of the SQL standard and is designed to be extensible by users in many aspects. Some of the features are ACID transactions, foreign keys, views, sequences, subqueries, triggers, user-defined types and functions, outer joins, and many more.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the PostgreSQL relational database management on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

It is now possible to upgrade LMDE 4 to version 5.
If you are an application developer you are probably already using a text editor or IDE, but if you are a novice you are likely overwhelmed by the sheer number of solutions out there. In any case, it pays to learn about new tools so that you can get the most out of them. Today, you’ll learn how to install juffEd Development Environment on Ubuntu 20.04. In addition to this, we’ll tell you a bit about it.
Developer CPasJuste has released pEMU 6.0 for the PS4, Nintendo Switch, Linux, and PS Vita. This new release adds Sega rom (Mega Drive, Master System, Game Gear, Mega CD…) support to the emulator suite. The pEmu suite are pretty stable emulators that can provide a very good alternative to Retroarch.
We will give you the feature summary of the KDE Plasma 5.25 desktop environment (upcoming).
KDE Plasma 5.25 is the 27th version of KDE Plasma desktop, not an LTS release. This release is followed by the prior 5.24 LTS, released in February. KDE Plasma 5.25 brings several exciting updates on the desktop UI, polished applets, widgets, a good set of gesture updates for touch-based devices and a massive list of bug fixes. Plasma 5.25 is based on Qt 5.15.2 and KDE Frameworks 5.94.
Next, I tried to enroll a otp for our Fedora account system, but found that the TOTP secret wouldn’t work. Further investigation showed that the onlykey NEO only supports sha1 for TOTP secrets and our account system uses SHA512. ;( There’s a old closed ticket about this on the onlykey firmware repo: https://github.com/trustcrypto/OnlyKey-Firmware/issues/101
There’s also no way to generate a ssh private key on the device (like you can using the opensc support on a yubikey). You can generate ecdsa sk openssh keys, which is great, but not too useful to me yet as RHEL7 and RHEL8 don’t support them.
Germany based ICP has launched a compact PC based on Intel’s processors (11th Gen Intel Core & Celeron) for DIN rail use. The DRPC-240-TGL comes with 8GB RAM by default although it can be expanded to 64GB through two DDR4 SO-DIMM slots. ICP ensures to deliver the DRPC-240-TGL in a ready-to-use form, meaning pre-assembled and with an OS installed (Win 10 or Linux).
The DRPC-240-TGL is offered in three processor variations, Intel Celeron 6305, Intel Core-i5-1145G7E and Intel Core-i7-1185G7E. The PC design allows the user to implement a PCIe expansion box (PCI Express x4) for add-on cards. The device also provides one M.2 2230 A-key and one M.2 3042/52/80 B-key for additional add-on cards. Furthermore, there is a 2.5” drive bay for SATA (6Gb/s) storage.
After attempting to learn how to play the piano after some previous experience with guitar and music theory in general, YouTuber EvolutionStoneware encountered a few difficulties when trying to learn the keys on a standard MIDI keyboard. Because of this, she created a DIY MIDI controller called the Root Commander that allows for a single note to be played based on the settings of several inputs.
Within the controller is an Arduino that reads the values from three potentiometers and determines the corresponding scale, key, and octave. Once stored, the firmware chooses the correct string containing either the scale, key, or octave depending on which range the values fall into. For example, setting the scale potentiometer to between 500 and 722 selects the “Dorian” scale. From here, these values are all shown on the integrated I2C OLED display in the center.
Last summer, Canaan introduced the Kendryte K510 tri-core RISC-V AI processor, now also known as Canaan K510, as an updated version of the Kendryte K210 with a much higher 3 TOPS of performance, but at the time, there were no development board and SDK.
But I’ve now just been informed of the availability of the Canaan Kendryte K510 CRB (customer reference platform) AI development kit with camera module and LCD display, as well as a software development kit with U-Boot, Linux, and AI tools which can be used to develop smart audio and computer vision applications.

There's a palpable change in the air regarding sustainability and environmental issues. Concern for the condition of the planet and efforts to do something about it have gone mainstream. To take one example, look at climate-based venture capitalism. The Climate Tech Venture Capital (CTVC) Climate Capital List has more than doubled in the past two years. The amount of capital pouring in demonstrates a desire and a willingness to solve hard climate challenges.
It's great that people want to take action, and I'm here for it! But I also see a real risk: As people rush to take action or jump on the bandwagon, they may unwittingly participate in greenwashing.
The Wikipedia definition of greenwashing calls it "a form of marketing spin in which green PR and green marketing are deceptively used to persuade the public that an organization's products, aims, and policies are environmentally friendly." In my view, greenwashing happens both intentionally and accidentally. There are a lot of good people out there who want to make a difference but don't yet know much about complex environmental systems or the depth of issues around sustainability.

 One of the types of software that’s important for a web developer is the web framework. A framework “is a code library that makes a developer’s life easier when building reliable, scalable, and maintainable web applications” by providing reusable code or extensions for common operations. By saving development time, developers can concentrate on application logic rather than mundane elements.
A web framework offers the developer a choice about how to solve a specific problem. By using a framework, a developer lets the framework control portions of their application. While it’s perfectly possible to code a web application without using a framework, it’s more practical to use one.
One thing that I would like to understand better is the place of code walking in macro programming. The Raskin paper explains that it is not possible to write a fully correct code walker in ANSI CL. Consfigurator currently uses Raskin’s best-effort portable code walker. Common Lisp: The Language 2 includes a few additional functions which didn’t make it into the ANSI standard that would make it possible to write a fully correct code walker, and most implementations of CL provide them under one name or another. So one possibility is to write a code walker in terms of ANSI CL + those few additional functions, and then use a portability layer to get access to those functions on different implementations (e.g. trivial-cltl2).
However, both On Lisp and Let Over Lambda, the two most substantive texts on CL macrology, both explicitly put code walking out-of-scope. I am led to wonder: does the Zen of Common Lisp-style macrology involve doing without code walking? One key idea with macros is to productively blur the distinction between designing languages and writing code in those languages. If your macros require code walking, have you perhaps ended up too far to the side of designing whole languages? Should you perhaps rework things so as not to require the code walking? Then it would matter less that those parts of CLtL2 didn’t make it into ANSI. Graham notes in ch. 17 of On Lisp that read macros are technically more powerful than defmacro because they can do everything that defmacro can and more. But it would be a similar sort of mistake to conclude that Lisp is about read macros rather than defmacro.

Hello everybody,
after a long time of waiting it is finally time - we cordially invite you to the German Perl/Raku Workshop 2023.
Next year's workshop will take place from Monday 28 February to Wednesday 1. March in the Saalbau Gallus in Frankfurt am Main.
Over the years, I have had a few things to say about technological change, churn, and the appearance of progress, a few of them touching on the evolution and development of the Python programming language. Some of my articles have probably seemed a bit outspoken, perhaps even unfair. It was somewhat reassuring, then, to encounter the reflections of a longstanding author of Python books and his use of rather stronger language than I think I ever used. It was also particularly reassuring because I apparently complain about things in far too general a way, not giving specific examples of phenomena for anything actionable to be done about them. So let us see whether we can emerge from the other end of this article in better shape than we are at this point in it.
Now, the longstanding author in question is none other than Mark Lutz whose books “Programming Python” and “Learning Python” must surely have been bestsellers for their publisher over the years. As someone who has, for many years, been teaching Python to a broad audience of newcomers to the language and to programming in general, his views overlap with mine about how Python has become increasingly incoherent and overly complicated, as its creators or stewards pursue some kind of agenda of supposed improvement without properly taking into account the needs of the broadest reaches of its user community. Instead, as with numerous Free Software projects, an unscrutable “vision” is used to impose change based on aesthetics and contemporary fashions, unrooted in functional need, by self-appointed authorities who often lack an awareness or understanding of historical precedent or genuine user need.
Fine. Opening a conversation in a friendly matter similar to an actual letter is okay. It's polite, I guess, though a little verbose in some attempt to show that thought and time has gone into it. Or maybe just to shift the content to signature ratio a bit.
You answer in similar fashion. Probably top posting, which means that you just hit "reply" and start typing without lending a thought to the fact that all previous messages in the conversation will be cited in your response.
Then that person replies. Again with the full "Hello, Person" introduction and gigantic signature. Before you know it you have a full conversation where each new message contains more than ten full "Hello, Person"s complete with filler text and automatically appended big signatures that nobody reads (see footnote).
A quick summary of it is that Jakob managed to implement Derek Sivers's method of staying in touch with hundreds of people[2], by which you categorize people into four levels of importance that dictate how often you should contact them. Sort of like MySpace's top friends feature but even more punishing.
One nauseating political meme has survived too long - the two-axis political-compass.
"You see", (someone explains), you might be left or right wing, but you can also be more or less authoritarian or libertarian.
I get the idea. People's political ideas don't really divide well into Left and Right, so a little nuance wanders in to bandage the oddity.
Phillips rises to the occasion, becoming the company that applied for the most patents.
On April 22, 2022, the Federal Circuit granted B# On Demand LLC's motion to dismiss its Federal Circuit appeal in Case No. 22-1357 (see below). Unified had won on all issues at the PTAB (IPR2020-00995), which resulted in claims 1–10, 13–22, and 25–34 of U.S. Patent 9,553,880 being found unpatentable. The patent is related to on-demand distribution of subscription media and had been asserted against Spotify.
In 2021, in more than 45% of all IPR institution decisions (420 of 918), the PTAB spent considerable time and resources dealing with the discretionary considerations under the NHK Spring-Fintiv rule. But with more than a year since Director Iancu stepped down from the USPTO, Fintiv and 314(a) denials have plummeted dramatically. In Q1 of 2022, only 37 petitions have been denied on procedural grounds, and such denials on procedural grounds are projected to decrease by 17% year-over-year as seen below.
PATROLL, Unified Patents’ only Crowd Sourced Prior Art platform, has hit numerous milestones since being launched in 2018. So far in 2022, there have been 81 contests announced, versus 42 in 2021, and currently 34 active contests with $68,000 in total prizes. We are extremely happy to announce that over the last month, 29 contests have ended with over 170 total submissions, and nearly $30,000 paid to winning submissions. That averages nearly 6 submissions per contest.
Pharmaceuticals expert Joachim Feldges has left the partnership and the Allen & Overy patent team. The 63-year-old Munich patent litigator had already surpassed the Magic Circle firm’s age-limit for the partnership. Now he has set up his own firm in Munich. With his departure, the patent team has finally completed its long-awaited generational change.
Social media reaction suggests that Europe’s patent community has met the CJEU’s latest decision on preliminary injunctions with broad approval. However, as is so often the case, the devil is in the detail.
Case law that finds only patents that have survived opposition or nullity suits worthy of a PI is discriminatory. Indeed, this case law excludes newly-granted IP rights, such as in the case referred by the Munich Regional Court. Patents never challenged with an opposition or nullity action are also excluded, with patent owners having no influence on either. Nevertheless, patent owners should still be able to access effective protection of their rights for such patents.
Tobias Pichlmaier, current presiding judge at the 37th Civil Chamber at the Munich Regional Court, therefore had no choice but to submit the question to the CJEU. Based on established case law, if the Munich Regional Court had granted a preliminary injunction, a second-instance court would almost certainly have overturned the decision.
Now, rather than dismissing a PI for an as-yet unchallenged patent, judges must take a closer look at the technology. They must also consider the possible validity of a patent-in-suit. As a result, a further backlog of cases might occur, since proceedings could take longer. But the CJEU has no doubt streamlined the judicial approach.

In recent years, both the EPO and national patent offices, lately the French INPI, have worked to improve the quality of granted patents. Many in the patent community have repeatedly criticised the EPO in particular for its long-pursued strategy of increasing efficiency. Stakeholders complained that the desire for high productivity led to problems in patent examinations, and thus to poorer quality. They claimed that patent examiners have insufficient time for the individual applications.
The EPO’s strategic plan for 2023, unveiled in 2019, focused on patent quality – but the negative effects of increased efficiency linger. This is specially in the minds of many stakeholders, who still do not trust the quality of patents.
Until patent quality visibly increases, as more patents survive oppositions and nullity suits unscathed, the infringement judges must take the matter into their own hands. They must examine patent validity intensively and decide, based on this, whether to grant a preliminary injunction.
[...]
As a result, the CJEU ruling contributes to a more uniform case law among German courts. This is especially important in view of the impending UPC, where German judges are sure to play an important role.
On 22 April 2022, the Danish Eastern High Court handed down its decision in yet another dispute concerning applied art and the question of originality and infringement under copyright law. The dispute concerned a plant box created by the Danish design company ferm Living and sold in various colours.
