  • Check and better order your photos on Kodi with these changes | ITIGIC - TechStony

    When we hear the name of Kodi, the first thing that comes to mind is a complete multimedia center for playing videos and music . However, this program goes much further and allows us to manage and reproduce other content such as television channels or photos.

    Precisely in these same lines we want to focus on this last element that we comment on, that is, in the management and visualization of images. This is something that we can directly carry out from this program without the need for additional ones. With this, what we want to tell you is that, as with video or audio content, photographic files can also be managed from here.

    As with the rest of the file types, when we start working with Kodi the first thing we have to do is create our photo library or libraries. From there, the application itself will already know the disk locations where we have these contents stored for later management. This is something that is surely familiar to us if we have already used it with videos or audios. In fact, below, we are going to show you a series of changes that we recommend you do to improve the viewing experience of these own photos.

  • Sync WM wallpaper with LightDM on Linux Mint :: Rafael Cavalcanti

    Linux Mint uses LightDM GTK greeter for the login screen. It tries to show each user’s wallpaper, and it works well if you stick to the default Cinnamon desktop environment.

    However, I use a standalone window manager (dwm) and my wallpaper is set by Nitrogen. This breaks the feature, unless we take some steps.

  • How to get useful answers to your questions

  • How to Install GCC Compiler Collection on CentOS 8 and Rocky Linux 8 – VITUX

    The GNU Compiler Collection (GCC) is a compiler software package with a collection of compilers for several languages. It is free and open-source software, which means that everyone has the opportunity to contribute or modify the application according to their own needs. GCC supports various programming languages, including C, C++, Objective-C, Fortran, Java and Ada. It also provides libraries such as libstdc++ for C++ and libgcj for Java.

    GCC uses a technology called “Recursive Descent Parsing”, which is very effective at finding errors in the code. GCC also provides a rich set of warnings that can be used to spot possible problems or bugs that may not have been detectable by the compiler itself. GCC performs some optimizations on both the intermediate code and the final machine code, but it does not perform as many optimizations as a commercial compiler would.

  • Bash Conditional Statements - OSTechNix

    In this guide, we will learn the usage of conditional statements in Bash scripting with examples. Decision-making is an important step in programming. There may be a situation where certain conditions have to be met and based upon that you have to write some logic. This is what a conditional statement does. The conditional statements allows you to write logic and take decisions. The concept that you read here will be the same for all the programming languages out there but with syntactic and implementation difference.

  • 7 handy tricks for using the Linux wget command

    Wget is a free utility to download files from the web. It gets data from the Internet and saves it to a file or displays it in your terminal. This is literally also what web browsers do, such as Firefox or Chromium, except by default, they render the information in a graphical window and usually require a user to be actively controlling them. The wget utility is designed to be non-interactive, meaning you can script or schedule wget to download files whether you're at your computer or not.

  • Intro – Modern Bash (Zsh) Scripting

    Writing shell scripts used to be a major, major pain for me. I remember many frustrating sessions, where I tried to find a misplaced quote or a missing backtick. I cursed shell script and only used it as a last resort.

    In those days, I would never, ever have thought, that I would write 100K lines of shell script code for a project and not even mind very much doing so.

    The main reason for this change of mind is ShellCheck. Combined with a colorizing syntax highlighter in an editor like Sublime Text ShellCheck makes the previously tedious search for that elusive missing backtick or doublequote super easy, barely an inconvenience: [...]

  • Apple fails to satisfy requirements set by ACM

    Apple has failed to satisfy the requirements set by the Netherlands Authority for Consumers and Markets (ACM) regarding payment systems for dating-app providers. ACM has come to this conclusion following an investigation into Apple’s statements of January 15, 2022. This means that Apple now has to pay ACM the first penalty payment of 5 million euros.

    Apple must adjust its conditions for access to the Dutch App Store for dating-app providers. In the App Store, dating-app providers must also be able to use payment systems other than Apple’s payment system. In addition, dating-app providers must have the ability to refer to payment systems outside of the app. This had been laid down in an order subject to periodic penalty payments that ACM imposed on Apple in August 2021. On December 24, 2021, the court ruled that this part of the order could be published.

  • HITMAN 3 Runs Well On Linux With Steam Play - Open-Source Radeon Performance Especially Good - Phoronix

    After being an Epic Games exclusive for its first year, HITMAN III launched on Steam last week. While there isn't a native Linux port for HITMAN 3, it does run wonderful under Steam Play with Proton for enjoying this Windows game on Linux complete with Vulkan API rendering. Here are some initial benchmarks of HITMAN 3 on Linux with NVIDIA GeForce and AMD Radeon graphics cards. [...] Most fascinating with the results is how well the performance is out of the Radeon "RADV" Vulkan driver with HITMAN 3 and stronger than NVIDIA RTX 30 series with their proprietary Vulkan driver. While not having a Radeon RX 6900 XT for testing (never received a review sample), the RX 6800 XT with HITMAN 3 could even outperform the GeForce RTX 3090.

  • The people deciding to ditch their smartphones

    The 36-year-old decided at the end of last year that getting rid of her handset would improve her mental health. So, over Christmas she told her family and friends that she was switching to an old Nokia phone that could only make and receive calls and text messages.

    She recalls that one of the pivotal moments that led to her decision was a day at the park with her two boys, aged six and three: "I was on my mobile at a playground with the kids and I looked up and every single parent - there was up to 20 - were looking at their phones, just scrolling away," she says.

Why we're migrating (many of) our servers from Linux to FreeBSD

There are many alternative operating systems to Linux and the *BSD family is varied and complete. FreeBSD, in my opinion, today is the "all rounder" system par excellence, i.e. well refined and suitable both for use on large servers and small embedded systems. The other BSDs have strengths that, in some fields, make them particularly suitable but FreeBSD, in my humble opinion, is suitable (almost) for every purpose.

So back to the main topic of this article, why am I migrating many of the servers we manage to FreeBSD? The reasons are many, I will list some of them with corresponding explanations. Read more

  1. [Old] On SSDs – Lifespans, Health Measurement and RAID

    Solid State Drive (SSD) have made it big and have made their way not only in desktop computing but also in mission-critical servers. SSDs have proved to be a break-through in IO performance and leave HDD far far behind in terms of Random IO performance. Random IO is what most of the database administrators would be concerned about as that is 90% of the IO pattern visible on database servers like MySQL. I have found Intel 520-series and Intel 910-series to be quite popular and they do give very good numbers in terms of Random IOPS. However, its not just performance that you should be concerned about, failure predictions and health gauges are also very important, as loss of data is a big NO-NO. There is a great deal of misconception about the endurance level of SSD, as its mostly compared to rotating disks even when measuring endurance levels, however, there is a big difference in how both SSD and HDD work, and that has a direct impact on the endurance level of SSD.

    I will mostly be taling about MLC SSD, now let’s start off with a SSD primer.

  2. My requirement for DNSSEC: a napkin

    I’m regularly made fun of when teaching DNSSEC because I tell people I use a “napkin” when creating DNSSEC keys to jot down the key tags (or key IDs), and it’s true: also during trainings I have the “napkin” – to be precise it’s a sheet of A4 paper on which I note modifications to schedule, timezones, whether I still owe answers to questions, and of course, the key IDs of DNSSEC keys.

  3. How to install and configure pCloud on Linux Mint | FOSS Linux

    PCloud offers a range of affordable storage plans that are pocket-friendly to anyone. It also provides a compelling size of free cloud storage and gives users complete control over their privacy, something many, if not all, users are looking for. Since pCloud is a Swiss-based application, it must adhere to strict Swiss privacy laws, meaning more protection for your files. However, it also puts forward a superb option for most personal and business users, hence an excellent option for all users. This software also interfaces with your browser via pCloud “save,” an extension for Opera, Firefox, and chrome. This extension allows you to directly save images to your particular “pCloud save” folder by only right-clicking on them. To add on, this app offers a pCloud web service for users who want to access their files but are away from their PCs. It works exactly like the pCloud app; there are menu links for browsing your files, accessing your public folder, pCloud rewind, backups from other cloud services, and your trash folder. Under this are links for accessing your shared folder, download links, crypto folder, and your audio files. To add a file to your web browser interface of pCloud, drag and drop the files into the specific folder by hovering over them, and pCloud will open an upload screen that displays your files uploading to the specified folder.
