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.

Excellent Utilities: Extension Manager - Browse, Install and Manage GNOME Shell Extensions

Filed under
Software

This series highlights best-of-breed utilities. We cover a wide range of utilities including tools that boost your productivity, help you manage your workflow, and lots more besides.

Part 22 of our Linux for Starters series explains how to install GNOME shell extensions using Firefox. 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.

Arti 0.5.0 is released: Robustness and API improvements

Filed under
Software
Security

Arti is our ongoing project to create a working embeddable Tor client in Rust. It’s not ready to replace the main Tor implementation in C, but we believe that it’s the future.

Right now, our focus is on making Arti production-quality, by stress-testing the code, hunting for likely bugs, and adding missing features that we know from experience that users will need. We're going to try not to break backward compatibility too much, but we'll do so when we think it's a good idea.

5 Top Free and Open Source Erlang Web Frameworks

Filed under
Software

One of the types of software that’s important for a web developer is the web framework. A framework “is a code library that makes a developer’s life easier when building reliable, scalable, and maintainable web applications” by providing reusable code or extensions for common operations. By saving development time, developers can concentrate on application logic rather than mundane elements.

A web framework offers the developer a choice about how to solve a specific problem. By using a framework, a developer lets the framework control portions of their application. While it’s perfectly possible to code a web application without using a framework, it’s more practical to use one.

  • 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.

Red Hat Hires a Blind Software Engineer to Improve Accessibility on Linux Desktop

Accessibility on a Linux desktop is not one of the strongest points to highlight. However, GNOME, one of the best desktop environments, has managed to do better comparatively (I think). In a blog post by Christian Fredrik Schaller (Director for Desktop/Graphics, Red Hat), he mentions that they are making serious efforts to improve accessibility. Starting with Red Hat hiring Lukas Tyrychtr, who is a blind software engineer to lead the effort in improving Red Hat Enterprise Linux, and Fedora Workstation in terms of accessibility. Read more
