  • Nostalgia and efficiency - MATE Desktop Tour

    It's time we started taking a look at MATE, the last major desktop environment I have never used. All I know about MATE is that it's basically a continuation of the GNOME 2 desktop, which I have used for a long time back when I started using Linux in 2006 on Ubuntu Dapper Drake. Let's see if that is true, and if GNOME 2, or MATE, is still up to the challenge in 2021.

  • System76: Laptops, Servers, and PCs Optimized for Linux and Open-Source Solutions

    Despite a lineage that predates Microsoft Windows and Apple macOS, the Linux operating system has struggled to gain traction in the mass commercial market. That challenge extends not only to the software but also to the dedicated hardware optimized to maximize the benefits of Linux on desktops and laptops. Linux was initially popular with tech enthusiasts, but the commercial PC industry skewed toward Windows and Intel consumer hardware. Part of the challenge for Linux related to its early lack of dedicated hardware solutions. The founders of System76 set out to make the Linux ecosystem more inviting by integrating the hardware and software components to provide consumers with easy access to desktops and laptops.

Programming Leftovers

  • with Statement – Linux Hint

    The Python with statement is a very advanced feature that helps to implement the context management protocol. When the programmer starts coding, they are basically using the try/except/finally to maintain the resources. But there is another way to do this automatically, called the ‘with’ statement. So, in this article, we will discuss how we can use the ‘with‘ statement. We can understand this with a very simple example. Whenever we code something to read or write a file, the first thing which we have to do is to open the file, and then we perform the read or write operations on that and, at last, we close the file so that all the resources will not be busy. So it means that we have to release the resource after we complete our work.

  • Assembly of Python External C++ procedure returning the value of string type

    Writing C++ procedure below we get a final answer as C++ string , then via sequence of operations which convert string to the pointer (say c) to "const char" and finally return required value via pointer to PyObject provided by PyUnicode_FromString(c) to Python Runtime module.

  • How to split string in C++ – Linux Hint

    Working with string data is an essential part of any programming language. Sometimes we need to split the string data for programming purposes. The split() function exists in many programming languages to divide the string into multiple parts. There is no built-in split() function in C++ for splitting string but many multiple ways exist in C++ to do the same task, such as using getline() function, strtok() function, using find() and erase() functions, etc. The uses of these functions to split strings in C++ have been explained in this tutorial.

  • Do while in c – Linux Hint

    Loops in C are divided into two parts. One is the loop body, and the other is the control statement. Each loop is unique in its way. Do while loop is alike to a while loop in some aspects. In this loop, firstly, all the statements inside the body are executed. In case the condition is true, then the loop is again executed until the condition becomes false. In this guide, we will shed some light on the examples of do-while loops.

  • C++ class constructors – Linux Hint

    Constructors are like functions. These are used to initialize the values and the objects of the class. These constructors are initiated when the object of a class is created. Constructor directly does not return any value. To get the value of the constructor, we need to describe a separate function as the constructor doesn’t have any return type. Constructor differs from the simple function in different ways. A constructor is created when the object is generated. It is defined in the public segment of the class. In this article, we will deliberate on all these types of constructors with examples.

  • Comparing Strings in Java – Linux Hint

    It is easier to understand the comparison of characters before learning the comparison of string literals. A comparison of strings is given below this introduction. With Java, characters are represented in the computer by integers (whole numbers). Comparing characters means comparing their corresponding numbers. With Java, uppercase A to uppercase Z are the integers from 65 to 90. A is 65, B is 66, C is 67, until Z, which is 90. Lowercase ‘a’ to lowercase ‘z’ are the integers from 97 to 122. ‘a’ is 97, ‘b’ is 98, ‘c’ is 99, until ‘z,’ which is 122. Decimal digits are the integers, 48 to 57. That is, ‘0’ is 48, ‘1’ is 49, ‘2’ is 50, until 9, which is 57. So, in this new order, digits come first before uppercase letters, which come next before lowercase letters. Before the digits, there is the bell, which is a sounding and not a printable character. Its number is 7. There is the tab character of the keyboard, whose number is 9. There is the newline character (pressing the Enter key), whose number is 10. There is the space character (pressing the space-bar key), whose number is 32. There is the exclamation character, whose number is 33. There is the forward-slash character, whose number is 47. ‘(’ has the number, 40 and ‘)’ has the number, 41.

  • How to use HashMap in Java – Linux Hint

    The column on the left has the keys, and the column on the right has the corresponding values. Note that the fruits, kivi, and avocado have the same color, green. Also, the fruits, grapes, and figs have the same color, purple. At the end of the list, three locations are waiting for their own colors. These locations have no corresponding fruits; in other words, these three locations have no corresponding keys.

Computer scientist showcases world's first RISC-V-based Linux PC coupled with an AMD RX 6700 XT GPU

Back when Nvidia was announcing the intentions to buy ARM and many industry analysts immediately expressed their concern regarding the status of the ARM architecture that might not remain open source for too long, SiFive came out with a big push for its RISC-V CPU architecture as a true open source alternative. Similar to the Windows-on-ARM initiative, SiFive promised to deliver a general use PC platform that would allow software developers to adapt the Windows and Linux-based code for the RISC-V processors. It only took SiFive a few months to launch its first PC motherboard called the HiFive Unmatched, which is based on the U7 SoC. However, since the RISC-V community is not that big, development on the PC platform is not exactly fast. Interestingly enough, Nvidia recently managed to enable RTX 3000 support for ARM-based laptops, and, almost at the same time, a RISC-V enthusiast managed to make an AMD RX 6700 XT work on Linux-based HiFive Unmatched system. This is essentially a double milestone for the RISC-V community. Hackster.io reports that computer scientist René Rebe first managed to make the HiFive Unmatched run Linux, and then added support for the Radeon RX 6700 XT GPU through the Mesa Gallium 21.1.5 driver. Apparently, the U7 SoC is not properly supported in Linux, but Rebe was able to work his magic and patched the Linux kernel to support both the RISC-V architecture and the RDNA2 GPU in around 10 hours. The GPU is not fully functional as of yet. It can display the GUI, can render 3D graphics in accelerated-mode and also decode hi-res videos, but cannot run games. Nevertheless, this is still an impressive achievement that is not facilitated by the SiFive team itself. Read more

  • Evgeni Golov: It's not *always* DNS

    Two weeks ago, I had the pleasure to play with Foremans Kerberos integration and iron out a few long standing kinks. It all started with a user reminding us that Kerberos authentication is broken when Foreman is deployed on CentOS 8, as there is no more mod_auth_kerb available. Given mod_auth_kerb hasn't seen a release since 2013, this is quite understandable. Thankfully, there is a replacement available, mod_auth_gssapi. Even better, it's available in CentOS 7 and 8 and in Debian and Ubuntu too! So I quickly whipped up a PR to completely replace mod_auth_kerb with mod_auth_gssapi in our installer and successfully tested that it still works in CentOS 7 (even if upgrading from a mod_auth_kerb installation) and CentOS 8.

  • [Older] How To Install MariaDB 10.5 on Ubuntu 20.04

    MariaDB is one of the most popular open-source databases next to its originator MySQL. The original creators of MySQL developed MariaDB in response to fears that MySQL will suddenly become a paid service due to Oracle acquiring it in 2010. With its history of doing similar tactics, the developers behind MariaDB have promised to keep it open source and free from such fears as what has happened to MySQL.

  • Save a dict to a file – Linux Hint

    Dictionary is a very famous object in python. And it is a collection of keys and values. The key of the dict must be immutable, and it can be integer, float, string, but neither a list nor a dict itself can be a key. So, sometimes we need to save the dict objects into a file. So we are going to see different methods to save a dict object in a file.

  • Introduction to RPM/YUM Package Management – Linux Hint

    Red Hat Package Manager is the default open-source package management utility built under General Public License (GPU). The package management system is for all Red Hat-based Linux derivatives like Fedora, RHEL, and CentOS. RPM facilitates system administrators with the basic five modes of package management operations: installing, updating, removing, querying, and verifying packages. Moreover, Yellowdog Updater Modified (YUM) is to RPM what APT package management tool is for dpkg utility in Debian packaging system: it resolves the package dependency issues of RPM. In this guide, we will briefly introduce YUM. Whereas, we will have an in-depth introduction and background to the RPM packaging system for Red Hat Linux distributions.

  • What is ngrep and How to Use It? – Linux Hint

    Even though tshark and tcpdump are the most popular packet sniffing tools that dig down to the level of bits and bytes of the traffic. ngrep is another command-line nix utility that analyzes network packets and searches for them on a given regex pattern. The utility uses pcap and GNU library to perform regex string searches. ngrep stands for Network grep that is similar to the regular grep utility. The only difference is that ngrep parses text in network packets by using regular or hexadecimal expressions. In this article, we learn about a command-line, feature-rich utility known as ngrep that is handy for quick PCAP analysis and packet dumping.

  • Kubectl Port Forward – Linux Hint

    Forwarding a port using kubectl is relatively easy, although it only operates with individual pods but not with services. Port forwarding is a valuable tool for debugging different applications and deployments in the Kubernetes cluster. For illustration, if one of your pods is acting strangely, you will need to link to it directly. As this is a microservice setting, you can utilize port forwarding to communicate with a back-end service that would otherwise be hidden. The Kubelet delivers all information entered into the stream to the destination pod and port. When designing Kubernetes applications, it’s common to wish for immediate use of a service from the surrounding environment without exposing it via a load balancer or perhaps an ingress resource. We can use kubectl to create a proxy that forwards all traffic from a local port to a port linked to our chosen Pod. The kubectl port-forward instruction can be utilized to accomplish this. The kubectl port-forward sends an appeal to the Kubernetes API. That implies the machine that runs it requires access to the API server, and all communication is tunneled through a single HTTP connection. By passing one (or more) local ports to a pod, we can access container content with this command. This command performs effectively when you are required to debug a malfunctioning pod. We are going to talk about a step-by-step method to check port forwarding using kubectl.

  • Kubectl Get Events To Sort By Time – Linux Hint

    While other resources have changes, errors, or other notifications that should be broadcasted to the system, Kubernetes events are generated automatically. There is not so much documentation on events, but they are a great help when troubleshooting problems in your Kubernetes cluster. When compared to many other Kubernetes objects, events have a lot of activity. Events have a one-hour life period by default, and a distinct etcd cluster is advised for scalability. Events on their own, when combined with the inability to filter or aggregate, may not be particularly valuable unless they are transferred to external systems. Kubernetes events are entities that inform you what’s going on inside a cluster, like the scheduler’s decisions and why some pods were ejected from a node. The API Server allows all key components and extensions (operators) to generate events. When something is not operating as planned, the first area to check at is events and network operations. If the failure is the outcome of earlier events or when performing post-mortem analysis, keeping them for a longer duration is critical. Kubernetes generates events every time any of the resources it manages changes. The entity that initiated the event, the kind of event, and the cause are generally included in these events. Now to sort events by time, you have to follow the appended steps described in this tutorial.

  • Introduction to Manjaro Package Manager Pacman – Linux Hint

    The Linux distributions package management system has covered a long way. The timely practice of software management by creating independent repositories, application packages, and installation tools made software accessible across environments. Similar to all other Linux distributions, Manjaro has a default package manager of Arch Linux. In this article, we learn to use the command-line package manager Pacman to add, remove, and update software packages from the distribution or user build repository. The tutorial also covers how to query details of installed packages on the system.
