  • GNU Toolchain Begins Landing LoongArch Support - Phoronix

    In addition to Loongson working on Linux kernel support for their MIPS-derived LoongArch CPU architecture, the first bits of the GNU toolchain support for this Chinese CPU architecture have been merged.

    The GNU Compiler Collection (GCC) LoongArch support hasn't yet been merged but the GNU Binutils archive saw the initial collection of LoongArch patches merged on Sunday morning.

  • Capacitive Touch Controller for FPGAs

    Most projects that interface with the real world need some sort of input device. Obviously this article is being written from a standardized “human interface device” but when the computers become smaller the problem can get more complicated. We can’t hook up a USB keyboard to every microcontroller since we often only need a few buttons, but even buttons can be a little bit too cumbersome for some applications. For something even simpler, we would like to turn your attention to capacitive touch controllers.

  • Meson v0.60 Build System Brings Numerous Improvements

    Meson 0.60 was released on Sunday as the newest version of this increasingly popular and widely-used cross-platform build system.

  • Josef Strzibny: You can in fact use schemas in migrations

    I saw well-intended recommendations not to use schemas in migrations lately. Although the advice of switching to raw SQL is a good one, we don’t have to give up on schemas entirely.

  • Software Development Life Cycle (SDLC) Automation

    Gone are the days when manual labor used to go through a rigorous time taking process in order to furnish quality products. Today, organizations have shifted their attention towards automated software. Each software goes through a development lifecycle to meet customer requirements of a high-quality product known as SDLC. In the growing software industry, developers compete to produce high-quality software while remaining within their range of cost and time limits.

    SDLC Automation helps achieve the above goals with minimum manual labor, time, and cost while maintaining a high level of productivity as well as efficiency. This article expounds upon the need for automation in the SDLC process and further sheds light on some of the aspects that software companies must start automating.

  • What is the Difference Between =, == and === in JavaScript?

    JavaScript is a programming language that allows us to create and develop web applications and web pages as well as make our websites more dynamic/interactive. Data can be calculated, manipulated, and validated using JavaScript.

    Like any other language, JavaScript has operators. An operator produces a result by performing some action on a single or multiple operands (data value). Let’s look at an example of 2+2 where the numbers are left and right side operands and the + is the operator. This + operator adds the two numbers together.

    With examples, we’ll examine and answer the question that what is the difference between the =,==, and === operators in JavaScript in this article.

  • Is JavaScript Object-Oriented?

    Object-Oriented Programming (OOP), is a programming approach that is used by every developer at some point in their life to organize software design around objects or data rather than logic or functions where an object is an entity that has some properties and some type. The benefits of using the OOP technique include modularity, reusability, security, productivity, flexibility, and is easily scalable and upgradeable.

  • TOAST.UI: Free, Open-source Interactive JavaScript application components

    While working on a project, I need a calendar library. As I do for every project, I tend to not use previously used libraries and try to learn and use something new.

    That's how I found Toast.ui, an open-source features-rich UI library for building production-ready apps.

  • YAML vs JSON – Which is better?

    Nowadays, almost every person is familiar with the standard format of JSON. Contrarily, individuals who use Docker are surely familiar with YAML. In simpler words, Docker is a toolkit which permits developers to run, build, deploy, modify as well as stop packages through a single API or commands. YAML is a new but popular language used to serialize data. First of all, we should perceive what data serialization is. Data serialization is the most common way of transforming data objects into byte streams used to store, transfer and distribute data on devices. However, they have similar objectives to store structures and data objects into files but distinctive ways to work.

    In this article, we first go through the features of JSON and YAML, then compare them in-depth to completely comprehend their advantages, and then briefly discuss which one is better.

  • Some Perl Code In Memory of a Great Scientist | martin [blogs.perl.org]

    On August 21, 2021, famous Polish mathematician Andrzej Schinzel passed away at the age of 84. He was one of the great minds behind modern number theory. May he rest in peace. I have extended one of my CPAN modules relating to his work and dedicated the release to his memory.

  • Remove None from the List Python

    In python, when a function returns nothing, it indirectly returns ‘None’. Due to the forthcoming ML (Machine Learning), our focus is now on understanding the None values. The goal behind this is that it is the crucial phase of data preprocessing. Hence, elimination of None values is crucial, so you must know how important it is. Let’s discuss certain techniques in which this is achieved. To replace none in python, we use different techniques such as DataFrame, fillna, or Series. No keyword in python declares the null objects and variables. In python, none refers to the class ‘NoneType’.

    We can allot None to many variables, and they all point toward a similar object. The interesting fact about none is that we can’t consider false as any. None is a blank string or a 0. Let’s demonstrate it with the help of examples. We use the Spyder compiler or different strategies to explain how python removes null values from the list.

  • Python LDAP example

    LDAP is a LIGHTWEIGHT DIRECTORY ACCESS PROTOCOL. It is an internet protocol that works on TCP/IP, and it is used to access/fetch the information from the directories. All the directories are not preferable; it is usually used to access those directories that are active.

  • Python Multiply List by Scalar

    In Python, the most elementary data building is the sequence. Each sequence element allotted a number – its index or placement. The starting point of the index is ‘0’, the second point is ‘1’, and so forth. Python offers six in-built types of sequences, but the most important or commonly used are lists, which we would discuss in this guide. Python list is the most useful data type. It can be written within a square bracket, and a comma separates every item in the list.

EasyOS version 2.9 was released on September 3, 2021 and 3.0 released on October 5, 2021. Version 2.9 was announced on Distrowatch, but not 3.0 as it was really a testing release for the 3.x version numbering. Thanks to the guys who tested 3.0, there have been many enhancements. Always more to do of course, and my to-list keeps getting added to. But, this is a point where we can feature-freeze and bring out a new release.

the Alpine release process

Filed under
GNU
Linux
Security

It’s almost Halloween, which means it’s almost time for an Alpine release, and all hands are on deck to make sure the process goes smoothly. But what goes into making an Alpine release? What are all the moving parts? Since we are in the process of cutting a new release series, I figured I would write about how it is actually done.

the beginning of the development cycle

The development cycle for an Alpine release is 6 months long: it begins immediately once the release is branched in aports.git: at that point, there is no longer a development freeze, and minor changes start flowing in.

Prior to the beginning of the development cycle, larger changes are proposed as system change proposals, an example of which being the change proposal introducing Rust to main for the Alpine 3.16 development cycle. The largest, most invasive proposals are coordinated by the Technical Steering Committee, while others may be coordinated by smaller teams, and individual maintainers. Anybody may create a system change proposal and drive it in Alpine, regardless of whether or not they have developer rights in the project.

As these system change proposals are accepted (possibly after a few rounds of revision), the underlying steps needed to implement the change are sequenced into the overall development schedule if needed. Otherwise, they are implemented at the discretion of the contributor driving the change proposal.

Trump's Social Media Platform and the Affero General Public License (of Mastodon)

Trump's Group has 30 days to remedy the violation, or their rights in the software are permanently terminated

In 2002, we used phrases like “Web 2.0” and “AJAX” to describe the revolution that was happening in web technology for average consumers. This was just before names like Twitter and Facebook became famous worldwide. Web 2.0 was the groundwork infrastructure of the “social media” to come.

As software policy folks, my colleagues and I knew that these technologies were catalysts for change. Software applications, traditionally purchased on media and installed explicitly, were now implicitly installed through web browsers — delivered automatically, or even sometimes run on the user's behalf on someone else's computer. As copyleft activists specifically, we knew that copyleft licensing would have to adjust, too.

Review: Ubuntu 21.10

Ubuntu 21.10 (code name Impish Indri) and its many variant flavors were released on October 14. This release is a non-Long Term Support release, meaning it will be supported for nine months. Like all new releases of Ubuntu, Ubuntu 21.10 comes with numerous updates and enhancements. The most notable of these changes are the customized GNOME 40 desktop and Firefox being a Snap instead of a Deb package. Both of these changes are explored in depth in this review. Installing Ubuntu 21.10 I began by downloading the 2.9GB ISO and copying it to a flash drive. Booting the computer from the flash drive resulted in an extremely familiar experience. Unfortunately, the new installer currently being worked on did not make it into this release, so Ubuntu 21.10 still provides the same installation experience as all the recent releases of Ubuntu.

Indie dev finds that Linux users generate more, better bug reports

An indie developer has found an interesting observation: Though only 5.8% of his game's buyers were playing on Linux, they generated over 38% of the bug reports. Not because the Linux platform was buggier, either. Only 3 of the roughly 400 bug reports submitted by Linux users were platform specific, that is, would only happen on Linux. The developer, posting as Koderski for developer Kodera Software on Reddit, makes indie game ΔV: Rings of Saturn—that's Delta V, or DV, for the non-rocket-science-literate. It's a hard science, physics-based space mining and piracy game that I quite like, personally, for its blend of playability that still honors the basics of spaceflight. If you quite like the space combat of, say, The Expanse, DV is a sim that might be for you. Koderski says he's sold a little over 12,000 copies of his game, and about 700 of those were bought by Linux players. "I got 1040 bug reports in total, out of which roughly 400 are made by Linux players," says Koderski's post. "That’s one report per 11.5 users on average, and one report per 1.75 Linux players. That’s right, an average Linux player will get you 650% more bug reports." Koderski's numbers are a limited sample size drawn from one person's experience, but tell a compelling story. Read more

  • Deploying containers with Consfigurator

    For some months now I’ve been working on some patches to Consfigurator to add support for Linux containers. My goal is to make Consfigurator capable of both performing the initial setup of a container and of entering the running container to apply configuration. For the case of unprivileged LXCs running as non-root, my work-in-progress branch can now do both of these things. As Consfigurator enters the container directly using system calls, it should be decently fast at configuring multiple containers on a host, and it will also be possible to have it do this in parallel. The initial setup for the container uses Consfigurator’s existing support for building root filesystems, and it should be easy to extend that to support arbitrary GNU/Linux distributions by teaching Consfigurator how to invoke bootstrapping tools other than debootstrap(8).
