  • AMD Secure Memory Encryption Has a Flaw, Now Disabled by Default in Linux Kernel

    According to a report from Phoronix, the Linux 5.15 kernel is receiving a new fix that involves disabling AMD's Secure Memory Encryption, or SME. This feature is normally enabled by default, but due to unexpected boot failures on some AMD machines, SME will now be disabled by default. Devs will update the Linux 5.15 kernel first, but the change will also move to prior kernels.

    AMD Secure Memory Encryption is a feature exposed to AMD's EPYC and Ryzen Pro processors that allows the CPUs to encrypt the memory at a hardware level. AMD says the feature offers no significant impact on system performance and works with any OS and application because it's hardware-accelerated and doesn't rely upon software.

  • [Older] Linux Kernel Concurrency Cheat Sheet

    Navigating Linux kernel APIs can be very time-consuming, so Linux ksplice guru Vegard Nossum put together a very handy time-saving cheat sheet to help traversing Linux kernel concurrency primitives.

    As a child, I spent countless hours playing games on my Nintendo Game Boy. As I grew older and started programming in QBasic on MS-DOS, I also got curious about how Game Boy games worked.

  • Habana Labs For Linux 5.16 To Bring Peer-To-Peer Support With DMA-BUF - Phoronix

    The drama around DMA-BUF code for the Habana Labs AI driver appears to be wrapping up with the Linux 5.16 cycle that is coming up.

    The Habana Labs driver changes were mailed out today for queuing in char/misc ahead of next month's Linux 5.16 merge window. This driver for supporting the AI inference and training accelerators at the Intel-owned company has some exciting updates for this next kernel release.

  • mesa recompiled with gallium drivers

    The guys have been reporting slow Nvidia performance, for example a report from forum member Keef here:

    https://forum.puppylinux.com/viewtopic.php?p=39261#p39261

    I had compiled all of the packages in OpenEmbedded without libllvm, as it is a hug library, about 60MB. However, it meant had to leave out some drivers in the 'mesa' package.

  • Mesa 22.0 Lands Some Patches Toward OpenCL Image Support - Phoronix

    Mesa 22.0-devel is one step closer to having OpenCL image support that is sought after by many individuals for allowing more OpenCL-enabled desktop software to work nicely with this open-source OpenCL component in Mesa.

    For nearly a year there has been the work-in-progress merge request implementing OpenCL 1.2 image support. That work was started by Red Hat's Karol Herbst.

    No, Inkscape isn't a scam. In fact, it's the best vector illustration tool on the planet. But, much like Krita just a few weeks ago, scammers have registered official-looking domains that are meant to trick people into downloading and installing ransomware. It's sad to see and I can't think of many ways we can combat this besides raising awareness.

There are plenty of Linux-based laptops available. There are also mini-PCs preloaded with Linux.

A few Linux-based smartphones are also present in the market.

How about tablets? Are there some good Linux-based tablets? The answer is not straightforward.

Many Linux-only system manufacturers focus on creating desktop computers. This is primarily due to the fact that the Linux experience on touch devices is no where close to what Android and iOS provide.

CuteFish – An Elegant, Beautiful and Easy-to-Use Linux Desktop

Filed under
Linux

CutefishOS is a new free and open-source desktop environment for Linux operating systems with a focus on simplicity, beauty, and practicality. Its goal is to create a better computing experience for Linux users.

Cutefish OS is among the newest kids on the block of desktop environments. And since it has been born at such a time when the KDE aesthetic leads in the UI/UX stand for Linux users, it features a design that is strikingly similar.

Given its goal of making a better desktop experience, the team uses KDE Frameworks, KDE Plasma 5, and Qt. My guess is that Qt is the source of its “cute” name. They seem to have collaborated heavily with JingOS, a beautiful Linux OS targeted at Tablets.

  • 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.

  • 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.

  • 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.

Rocky Linux: An Enterprise-Ready CentOS Replacement

For a long time, CentOS was a reliable choice for a Linux-based servers, because it was effectively a free version of Red Hat Enterprise Linux (RHEL). All the features that made RHEL the dominant enterprise-class Linux were included in CentOS. On December 8th, 2020, Red Hat, which had acquired the CentOS project, abruptly announced a change in its focus in the wake of Red Hat’s acquisition by IBM. They announced they would be shifting all of their investment in CentOS Linux from the popular downstream CentOS distribution. This move also meant that CentOS would be upstream of RHEL, rather than downstream, so CentOS users would be in effect beta testers for RHEL. Since there were so many users relying on a CentOS version that would be unsupported sooner than they planned for, the community sensed a need for a new project. In response, the original CentOS founder Gregory Kurtzer is leading the effort to create a new version of the distro, to achieve the original goals of CentOS. Kurtzer told he was thinking about creating a new version of CentOS ever since Red Hat acquired it in 2014. Read more
