  • 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.

    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.

  • What is distributed consensus for site reliability engineering? | Opensource.com

    With microservices, containers, and cloud native architectures, almost every application today is going to be a distributed application. Distributed consensus is a core technology that powers distributed systems.

    Distributed consensus is a protocol for building reliable distributed systems. You cannot rely on "heartbeats" (signals from your hardware or software to indicate that they're operating normally) because network failures are inevitable.

    There are some inherent problems to highlight when it comes to distributed systems. Hardware will fail. Nodes in a distributed system can randomly fail.

    This is one of the important assumptions you have to make before you design a distributed system. Network outages are inevitable. You cannot always guarantee 100% network connectivity. Finally, you need a consistent view of any node within a distributed system.

  • How Cloud AI Developer Services empower developers

    It’s been almost 11 years since Marc Andreessen famously posted, “Software is eating the world.” Over the last decade in IT, we’ve seen some amazing transformations happen – from companies fundamentally changing the way they deliver software to how we as consumers use web and mobile applications and services in our daily lives. Research shows that the average person in the U.S. now uses at least four to five software programs a day to do their job – partially due to the pandemic.

    Developing software has emerged as perhaps the most critical business function for companies as they undergo digital transformation to adapt to fast-paced change, delight their customers, and stand out from competitors. As such, the role of software developers has evolved at such a rapid pace that it is now more common to deliver software u

  • What is next for Open Source- Alma Linux and beyond | Business Insider India

    When Red Hat announced that it will no longer support open-source CentOS, a wave of disturbance was caused throughout the open-source community. In response, the open-source community formed an alliance and started building alternatives for CentOS.
    While they initially named it Lenix, which was a paid offering and was initially restricted to hosting providers, its eventual success led the community to make it 100% free and open-source and renamed it to AlmaLinux.
    Today, AlmaLinux has delivered over three releases with millions of downloads. It has become an alternative platform for developers for CentOS Stream and Red Hat Enterprise Linux. Even though its user-facing features are limited, its speed and agility have made it an attractive avenue for the open-source community.

Digitally signing PDF documents in Linux: with hardware token & Okular

Filed under
KDE
Software

We are living in 2022. And it is now possible to digitally sign a PDF document using libre software. This is a love letter to libre software projects, and also a manual.

For a long time, one of the challenges in using libre software in ‘enterprise’ environments or working with Government documents is that one will eventually be forced to use a proprietary software that isn’t even available for a libre platform like GNU/Linux. A notorious use-case is digitally signing PDF documents.

Recently, Poppler (the free software library for rendering PDF; used by Evince and Okular) and Okular in particular has gained a lot of improvements in displaying digital signature and actually signing a PDF document digitally (see this, this, this, this, this and this). When the main developer Albert asked for feedback on what important functionality would the community like to see incorporated as part this effort; I had asked if it would be possible to use hardware tokens for digital signature. Turns out, poppler uses nss (Network Security Services, a Mozilla project) for managing the certificates, and if the token is enrolled in NSS database, Okular should be able to just use it.

Accessibility in Fedora Workstation

Filed under
Red Hat

The first concerted effort to support accessibility under Linux was undertaken by Sun Microsystems when they decided to use GNOME for Solaris. Sun put together a team focused on building the pieces to make GNOME 2 fully accessible and worked with hardware makers to make sure things like Braille devices worked well. I even heard claims that GNOME and Linux had the best accessibility of any operating system for a while due to this effort. As Sun started struggling and got acquired by Oracle this accessibility effort eventually trailed off with the community trying to pick up the slack afterwards. Especially engineers from Igalia were quite active for a while trying to keep the accessibility support working well.

But over the years we definitely lost a bit of focus on this and we know that various parts of GNOME 3 for instance aren’t great in terms of accessibility. So at Red Hat we have had a lot of focus over the last few years trying to ensure we are mindful about diversity and inclusion when hiring, trying to ensure that we don’t accidentally pre-select against underrepresented groups based on for instance gender or ethnicity. But one area we realized we hadn’t given so much focus recently was around technologies that allowed people with various disabilities to make use of our software. Thus I am very happy to announce that Red Hat has just hired Lukas Tyrychtr, who is a blind software engineer, to lead our effort in making sure Red Hat Enterprise Linux and Fedora Workstation has excellent accessibility support!

Raspberry Pi Zero Prints Giant Pictures with Thermal Receipt Printer

Filed under
Hardware

It’s no secret that thermal receipt printers can print much more than receipts, but this Raspberry Pi project, created by a maker known as -PJFry- on Reddit, has taken the idea to a new extreme. With the help of a Raspberry Pi Zero, they’ve coded an application to print huge, poster-sized images (opens in new tab) one strip at a time on their thermal printer.

Inspiration for this project came from similar online projects where users print large-scale images using regular printers or thermal printers like the one used in this project. In this case, however, -PJFry- coded the project application from scratch to work on the Pi Zero. It works by taking an image and breaking it into pieces that fit across the width of the receipt printer and printing it one strip at a time. Then, these strips can be lined up to create a full-sized image.

It is the only microelectronics project we can find that -PJFry- has shared, but it’s clear they have a great understanding of our favorite SBC to craft something this creative from scratch. According to -PJFry-, the project wasn’t created for efficiency but more for fun as a proof of concept. The result is exciting and provides an artistic take on the Raspberry Pi’s potential.

Because of a bug, our guide explains that it’s not possible to install the extensions using the Snap version of Firefox. Instead, you need to install the deb package for Firefox (or use a different web browser).

However, if you have updated to Ubuntu 22.04, you’ll find that trying to install Firefox using apt won’t install a .deb version. Instead, it fetches a package that installs the Firefox Snap. You can install a Firefox deb from the Mozilla Team PPA. But there has to be an easier way to install and manage GNOME Shell Extensions.

Why I think the GNOME designers are incompetent

Filed under
GNOME

But GNOME folk didn't know how to do this. They don't know how to do window management properly at all. So they take away the title bar buttons, then they say nobody needs title bars, so they took away title bars and replaced them with pathetic "CSD" which means that action buttons are now above the text to which they are responses. Good move, lads. By the way, every written language ever goes from top to bottom, not the reverse. Some to L to R, some go R to L, some do both (boustrophedon) but they all go top to bottom.

The guys at Xerox PARC and Apple who invented the GUI knew this. The clowns at Red Hat don't.

There are a thousand little examples of this. They are trying to rework the desktop GUI without understanding how it works, and for those of us who do know how it works, and also know of alternative designs these fools have never seen, such as RISC OS, which are far more efficient and linear and effective, it's extremely annoying.

    I recently got in the need of splitting quite large amount of audio files into smaller equal parts. The first thought that came to my mind was – probably thousand or more people had similar problem in the past so its already solved – so I went directly to the web search engine.

    The found solutions seem not that great or work partially only … or not work like I expected them to work. After looking at one of the possible solutions in a bash(1) script I started to modify it … but it turned out that writing my own solution was faster and easier … and simpler.

    And I know how to select any adjacent sibling of an element (which follows it) with div ~ p.

    And I learned how to select an element when it only has one child with p:only-child a (even though they are the only element on their line, markdown will wrap the [link](#) elements in a paragraph tag).

    But how do I select the previous sibling of an element? Something like p:before(hr) which would select all paragraphs that precede an <hr> element.

  • Make a temporary file on Linux with Bash | Opensource.com

    When programming in the Bash scripting language, you sometimes need to create a temporary file. For instance, you might need to have an intermediary file you can commit to disk so you can process it with another command. It's easy to create a file such as temp or anything ending in .tmp. However, those names are just as likely to be generated by some other process, so you could accidentally overwrite an existing temporary file. And besides that, you shouldn't have to expend mental effort coming up with names that seem unique. The mktemp command on Fedora-based systems and tempfile on Debian-based systems are specially designed to alleviate that burden by making it easy to create, use, and remove unique files.

    First-generation version control systems made collaboration possible, but it was painful. Deleting, renaming, or creating new files wasn't easily done. Tracking files across multiple directories as part of one project was impossible. Branching and merging were confusing. Locks worked by copying a file with read-only or read-write UNIX permissions. Inevitably, programmers didn't want to wait for someone else to finish editing, so they got around the lock system with a simple chmod.
