Best Image Compression Apps for Linux

Filed under
Software

This article will post a list of useful command line and graphical utilities that allow you to compress image files to save local or remote disk space. Some of these applications provide “lossless” options that reduce size of image files with no or minimal loss of quality. Note that image compression is not the same as resizing, rescaling or altering geometry of images to reduce size. Image compression involves manipulating quality of images using various compression algorithms. Usually, quality of colors, individual pixels and transparency is manipulated to compress images and save disk space.

  • Mesa 21 Broke VAAPI Hardware Encoding On Machines With AMD Graphics Cards. A Fix Is Coming. - LinuxReviews

    Those of you who have tried to hardware encode video using AMD hardware after upgrading to Mesa 21 may have noticed that the encoded video is, in fact, not a video - it's some kind of odd slide-show with one new frame every 5 seconds or so. Mesa 20.3 didn't have that problem, Mesa 21 and the newly released 21.0.2 bug-fix do. The Mesa developers are aware of the problem we are referring to and a patch has been merged into the upcoming 21.0.3 version scheduled to be released around two weeks from now.

Fedora Linux Download ISO 64-bit

We can download Fedora Linux free of cost to install on PC, Laptop, or virtual machines. It is developed and maintained by the Fedora project community while sponsored by Red Hat. It came into existence when in 2003 Red Hat decided to turn its end-user Linux distribution into a community project, and so the Fedora distribution was born. Fedora uses and publishes software that are available under a free license. The project is led by the Fedora Project Board, which includes members of the community as well as Red Hat employees.

The key goal of developing Fedora is to provide a new, versatile, and free ( open source ) operating system. And being an upstream source code of the commercial Red Hat Enterprise Linux distribution, it helps a lot in developing and providing stability to RHEL.

Therefore, in short, it is a testing platform for many new technologies, and technologies that are considered available will eventually be added to Red Hat Enterprise Linux.

  • Create a JSON Response in Python

    JSON (JavaScript Object Notation) file is a very popular medium to interchange data between different formats. It contains data in text format that is supported by various languages such as Python, PHP, PERL, etc. The main purpose of the JSON file is to transfer data between the server and the client. The requests are generated by Python to retrieve the data from a particular resource URI. If the response of the request is returned in JSON format then the content of the response can be retrieved using the response.json() function. It returns the response by using a Python dictionary object. How this function can be used to parse JSON response using the Python request library will be shown in this tutorial.

  • Use of Django Request and Response Objects – Linux Hint

    The Request-response cycle is used to transfer the data between the client and server in all types of web APIs. The client-server architecture is used in the Django framework to implement the web application. The request and response are the two main components of the client-server application. An HttpRequest object is created in the Django application when a client requests any resource. A particular view function is used to handle the request and send the response using the HttpResponse object. The uses of different attributes and methods of HttpRequest and HttpResponse classes of the Django framework will be explained in this tutorial.

  • Form Validation in Django – Linux Hint

    Form validation is a very important task for any web application to enter valid data in the database. The users of the application will not be able to insert invalid data if the form data are validated before submitting. Django is called MVT (Model View Template) based framework where the task of the controller is done by this framework itself. The database-related tasks are done by Model and the data are presented to the template using View. The fields of a form are generated based on the particular model that will insert data into the Django database after validation. One type of validation is done by the browser-based on the field type that is defined in the model. Using the is_valid() function is another way to check the form data whether they are valid or not after submitting the form. This tutorial will show you how the data can be inserted into the Django database after validating the form.

  • How to Build a Basic Search for a Django Site? – Linux Hint

    A particular content of any site is normally retrieved by the users through Google search. However, if this search option is implemented on the website, then the users can easily find their desired content within the site without using Google search. . Another benefit of adding a search option within a website is that the developer can manage the searching output properly. That means he can control which content of the site will appear or not. This tutorial will show the process of implementing the basic search in the Django site.

  • How Do You Make Chown Recursive? – Linux Hint

    You may sometimes find errors while using any Linux operating system such as denied while editing a file. This is because of fewer rights on that particular file. Chown is usually abbreviated as “change ownership”, which means that the Chown is an instruction for changing the owner of a group of files and folders on Linux. Moreover, you need to modify the owner of a folder that holds all of the documents in certain situations. You might have to consume recursive chown, which is one of the choices of the chown instruction. Recursive means chown will be done for all documents in the specified directory, and also files and folders inside all sub-directories. You’ll discover how to recursively modify the directory and file authorizations while using the chown instruction in this guide.

  • How to Use Linux Chrt Command? – Linux Hint

    While using Linux operating system, multiple programs wait to be converted into a process for execution. When a program changes into a process, a lot of attributes are set that can be manipulated. For this, the Linux system provides a helpful tool to set or fetch real-time attributes of a process.

    The “chrt” command is a part of a low-level Linux utility that is not only used to set attributes on runtime but also to change the scheduling policy of a process and set its priority. It uses the existing PID of any waiting program to set and retrieve a schedule of real-time attributes. Simply, the scheduler decides which process is executed by the CPU first when the “chrt” command changes its priority.

  • Clusterssh – Administer multiple ssh or rsh shells simultaneously

    The command opens an administration console and an xterm to all specified hosts. Any text typed into the administration console is replicated to all windows. All windows may also be typed into directly.
    This tool is intended for (but not limited to) cluster administration where the same configuration or commands must be run on each node within the cluster. Performing these commands all at once via this tool ensures all nodes are kept in sync.

    Connections are opened using ssh which must be correctly installed and configured.

    Extra caution should be taken when editing files as lines may not necessarily be in the same order; assuming line 5 is the same across all servers and modifying that is dangerous. It's better to search for the specific line to be changed and double-check all terminals are as expected before changes are committed.

  • Radeon Vulkan Driver Adds Option Of Rendering Less For ~30% Greater Performance - Phoronix

    If your current Vulkan-based Radeon Linux gaming performance isn't cutting it and a new GPU is out of your budget or you have been unable to find a desired GPU upgrade in stock, the Mesa RADV driver has added an option likely of interest to you... Well, at least moving forward with this feature being limited to RDNA2 GPUs for now.

    RADV as Mesa's Radeon Vulkan driver has added an option to allow Variable Rate Shading (VRS) via an environment variable override. This RADV addition is inspired by the likes of NVIDIA DLSS for trading rendering quality for better performance but in its current form is a "baby step" before being comparable to DLSS quality and functionality.

  • Bas Nieuwenhuizen: A First Foray into Rendering Less

    In RADV we just added an option to speed up rendering by rendering less pixels.

    These kinds of techniques have become more common over the past decade with techniques such as checkerboarding, TAA based upscaling and recently DLSS. Fundamentally all they do is trading off rendering quality for rendering cost and many of them include some amount of postprocessing to try to change the curve of that tradeoff. Most notably DLSS has been widly successful at that to the point many people claim it is barely a quality regression.

    Of course increasing GPU performance by up to 50% or so with barely any quality regression seems like must have and I think it would be pretty cool if we could have the same improvements on Linux. I think it has the potential to be a game changer, making games playable on APUs or playing with really high resolution or framerates on desktops.

    [...]

    VRS is by far the easiest thing to make work in almost all games. Most alternatives like checkerboarding, TAA and DLSS need modified render target size, significant shader fixups, or even a proprietary integration with games. Making changes that deeply is getting more complicated the more advanced the game is.

    If we want to reduce render resolution (which would be a key thing in e.g. checkerboarding or DLSS) it is very hard to confidently tie all resolution dependent things together. For example a big cost for some modern games is raytracing, but the information flow to the main render targets can be very hard to track automatically and hence such a thing would require a lot of investigation or a bunch of per game customizations.

Kubernetes became the primary orchestration tool and was initially supporting stateless applications, commonly referred to as the cattle vs. pets approach. However, data-centric applications need stateful-ness while still leveraging the cattle vs. pet approach. Microservices, Containers, and Kubernetes are now moving mainstream as increasingly more stateful applications are adopting them.

    FLoC is a terrible idea that should not be implemented. Google’s experimentation with FLoC is also deeply flawed . We hope that this site raises awareness about where the future of Chrome seems to be heading, and why it shouldn't.

    FLoC takes most of your browsing history in Chrome, and analyzes it to assign you to a category or “cohort.” This identification is then sent to any website you visit that requests it, in essence telling them what kind of person Google thinks you are. For the time being, this ID changes every week, hence leaking new information about you as your browsing habits change. You can read a more detailed explanation here .

    Because this ID changes, you will want to visit https://amifloced.org often to see those changes.

  • The Brave browser basics: what it does, how it differs from rivals

    Boutique browsers try to scratch out a living by finding a niche underserved by the usual suspects. Brave is one of those browsers.

    Brave has gotten more attention than most alternate browsers, partly because a co-founder was one of those who kick-started Mozilla's Firefox, partly because of its very unusual — some say parasitical — business model.

  • Olimex RP2040-PICO-PC “computer” to feature RP2040-Py Raspberry Pi Pico compatible module

    We previously wrote it was possible to create a Raspberry Pi RP2040 board with HDMI using DVI and programmable IOs to output video up to 640×480 at 60 Hz with the microcontroller’s Cortex-M0+ cores clocked at 252 MHz.

    At the time, we also noted Olimex was working on such a board with RP2040-PICO-PC designed to create a small Raspberry Pi RP2040 computer with HDMI/DVI video output. The Bulgarian company has now manufactured the first prototype, but due to supply issues with the Raspberry Pi Pico board, they also designed their own RP2040-PICO module since they’ve got a reel of Raspberry Pi RP2040 microcontrollers.

  • 5 signs you're a groff programmer

    I first discovered Unix systems in the early 1990s, when I was an undergraduate at university. I liked it so much that I replaced the MS-DOS system on my home computer with the Linux operating system.

    One thing that Linux didn't have in the early to mid-1990s was a word processor. A standard office application on other desktop operating systems, a word processor lets you edit text easily. I often used a word processor on DOS to write my papers for class. I wouldn't find a Linux-native word processor until the late 1990s. Until then, word processing was one of the rare reasons I maintained dual-boot on my first computer, so I could occasionally boot back into DOS to write papers.

    Then I discovered that Linux provided kind of a word processor. GNU troff, better known as groff, is a modern implementation of a classic text processing system called troff, short for "typesetter roff," which is an improved version of the nroff system. And nroff was meant to be a new implementation of the original roff (which stood for "run off," as in to "run off" a document).

    In the Microsoft Exchange Server hack, an estimated 250,000 machinesworldwide might have been affected by a vulnerability that allowed hackers to control the machines and even infect other systems in the internal network of the targeted companies. Four major vulnerabilities in Microsoft Exchange Server were reported to Microsoft in early January. Unfortunately, it wasn’t until early March that Microsoft released patches, according to ZDNet. These vulnerabilities were used by the hackers during the period that Microsoft had either not released the patches, or companies had not upgraded their systems and installed the patches.

Elephant and Its Ivory

LIVES at risk. This is a travesty. REPUBLIC OF NAMIBIA'S MINISTRY OF ENVIRONMENT, FORESTRY AND TOURISM: "We should manage elephants based on science and not emotions." By auctioning/selling off 170 live elephants? Give us a break. Oftentimes, animals were to make a sacrifice over humans because they are just "animals", so they can't speak to us, and can't protest. We're asked to assume they're just the least important, therefore we can eradicate (or "cull") them -- as simple as that. How I wish the the Animal Kingdom will become a force and burn this kind of society just to make a statement -- and then, maybe, humans will truly realise the value of animal rights. Shame on those African countries which don't give a shit about all those people who tirelessly devoted their time and life to protecting the wild animals, and specifically the elephants. Animals can't speak, but they can see you and they can feel you; just look into and gaze at their eyes, doesn't that give you goosebumps? Burn.

  • The state of toolchains in NetBSD
                     
                       

    While FreeBSD and OpenBSD both switched to using LLVM/Clang as their base system compiler, NetBSD picked a different path and remained with GCC and binutils regardless of the license change to GPLv3. However, it doesn't mean that the NetBSD project endorses this license, and the NetBSD Foundation's has issued a statement about its position on the subject.

                       

    Realistically, NetBSD is more or less tied to GCC, as it supports more architectures than the other BSDs, some of which will likely never be supported in LLVM.

                       

    As of NetBSD 9.1, the latest released version, all supported platforms have recent versions of GCC (7.5.0) and binutils (2.31.1) in the base system. Newer (and older!) versions of GCC can be installed via Pkgsrc, and the following packages are available, going all the way back to GCC 3.3.6: [...]

  • OpenTTD Went to Steam to Solve a Hard Problem - Boiling Steam

    OpenTTD, the free and open-source software recreation of Transport Tycoon Deluxe, has been a popular game for a long time, but recently something unusual happened. The team behind the project decided to release the game on Steam (still free as always) and this has changed everything. Let me explain why this matters. If you have ever played OpenTTD on Linux, let me venture that you have probably relied on your distro’s package manager to keep your game up-to-date. In theory, this is the BEST way to keep your packages up to date. Rely on maintainers. In practice however, it’s far from being something you can rely on, beyond security updates. Debian stable tends to have really old packages, sometimes years behind their latest versions. So on Debian stable you end up with OpenTTD 1.08 as the most recent version. That’s what shipped in April 2018. Just about 3 years old.

  • Portal Stories: Mel gets Vulkan support on Linux in a new Beta | GamingOnLinux

    Portal Stories: Mel, an extremely popular and highly rated mod for Portal 2 just had a new Beta pushed out which adds in Vulkan support for Linux. Much like the update for Portal 2 that recently added Vulkan support, it's using a special native build of DXVK, the Vulkan-based translation layer for Direct3D 9/10/11. Compared with the Portal 2 update, in some of my own testing today it seems that Portal Stories: Mel seems to benefit from the Vulkan upgrade quite a bit more in some places. At times giving a full 100FPS increase! So for those on weaker cards, this will probably be an ideal upgrade. Another game to test with Vulkan is always great too.

All modern Linux firewall solutions use this system for packet filtering. [...] The default behavior of the UFW Firewall is to block all incoming and forwarding traffic and allow all outbound traffic. This means that anyone trying to access your server will not be able to connect unless you specifically open the port. Applications and services running on your server will be able to access the outside world.
