  • RenderDoc 1.15 Released For Cross-Platform/API Graphics Debugging - Phoronix

    RenderDoc continues maturing gracefully as the leading frame-capture based graphics debugging system for OpenGL / Direct3D / Vulkan across all major operating systems as well as some consoles.

  • AMD PMC Updates, Intel Alder Lake HID, Gigabyte-WMI Patches Land In Linux 5.14 - Phoronix

    While solidly into the "fixes" stage of Linux 5.14 kernel development, the x86 platform driver pull request this week -- which has already been merged to mainline -- does have some new additions worth mentioning.

    Merged into the Linux 5.14 development code yesterday was a batch of platform-drivers-x86 changes.

  • Mozilla ups its VPN game – and the price – with split tunneling for Android, iOS

    Browser maker Mozilla has enhanced its Virtual Private Network (VPN) service with split tunnelling and doubled the monthly pricing plan for new customers that don't want to commit to a one year contract.

    The VPN service was launched a little more than a year ago, and Moz has since gradually added features and expanded the number of countries where it is available.

    One glaring omission was split tunnelling – the ability to divide traffic and select which apps go through the encrypted VPN tunnel or the open network. Available on Android and iOS, the feature is one that has, according to Mozilla, "been requested by many users." It's certainly handy for high-bandwidth scenarios that might not need a full-on VPN.

  • Vivaldi 4.1 Offers a New Command Chains System and Accordion Tabs

    Vivaldi 4.1 comes with a range of improvements and fixes that will help you save time and get more out of your browsing.

    Vivaldi comes from the same team that developed Opera back in the day. It is intended for power users and provides an impressive level of control over the interface. Vivaldi is one of the lesser-known browsers, but it is actually a really good choice if you value customization and privacy above all else.

  • Using Cache::Memcached and its ->stats method?

    It's very slow if you have more than a few thousand keys in memcached. Not an unusual use case I think? I've got a fix here, which appears to DTRT: https://rt.cpan.org/Ticket/Display.html?id=138133. Maybe? I didn't spend too long looking at memcached's low level wire protocol.

  • Excellent Free Tutorials to Learn PostScript

    PostScript is an interpreted, stack-based language similar to Forth but with strong dynamic typing, data structures inspired by those found in Lisp, scoped memory and, since language level 2, garbage collection.

    The language syntax uses reverse Polish notation, which makes the order of operations unambiguous, but reading a program requires some practice.

    PostScript is a Turing-complete programming language, belonging to the concatenative group. This means that any program you can write in any programming language, you can write in PostScript (albeit it will be slower).

    PostScript files are (generally) plain text files and as such they can easily be generated by hand or as the output of user written programs. As with most programming languages, postscript files (programs) are intended to be, at least partially, human-readable.

    Here’s our recommended tutorials to learn PostScript.

  • Fixing an Interoperability Bug in LibreOffice: Missing Lines from DOCX (part 1/3)

    In LibreOffice, interoperability is considered a very important aspect of the software. Today, LibreOffice can load and save various file formats from many different office applications from different companies across the world. But bugs are inevitable parts of every software:there are situations where the application does not behave as it should, and a developer should take action and fix it, so that it will behave as it is expected by the user.

    What if you encounter a bug in LibreOffice, and how does a developer fix the problem? In these series of articles, we discuss the steps needed to fix a bug. In the end, we will provide a test and make sure that the same problem does not happen in the future.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
