Ubuntu

  • Finserv open source infrastructure powers digital transformation

    Covid-19 pandemic has presented unprecedented challenges and opportunities for financial institutions to embrace digital transformation initiatives at pace and scale. Finservs are enhancing their purview of digital transformation initiatives to stay relevant and create a technology foundation that enables them to quickly bounce back from future contingencies.

    Finserv digital transformation is spurred by technology, and the leading technologies spurring digital transformation are open source. It is fair to say that open source technologies are playing a key role in digital transformation.

    Financial institutions require a comprehensive portfolio of digital infrastructure and interconnection choices, both physical and virtual, and a wide range of cloud, and SaaS options to deliver that change.

  • How your organisation’s equipment policy can impact the environment

    At the Endless OS Foundation, we’ve recently been updating some of our internal policies. One of these is our equipment policy, covering things like what laptops and peripherals are provided to employees. While updating it, we took the opportunity to think about the environmental impact it would have, and how we could reduce that impact compared to standard or template equipment policies.

    How this matters

    For many software organisations, the environmental impact of hardware purchasing for employees is probably at most the third-biggest contributor to the organisation’s overall impact, behind carbon emissions from energy usage (in building and providing software to a large number of users), and emissions from transport (both in sending employees to conferences, and in people’s daily commute to and from work). These both likely contribute tens of tonnes of emissions per year for a small/medium sized organisation (as a very rough approximation, since all organisations are different). The lifecycle emissions from a modern laptop are in the region of 300kgCO2e, and one target for per-person emissions is around 2.2tCO2e/year by 2030.

Possible changes to Debian's decision-making processes

To a great extent, Debian leaves decisions in the hands of its individual developers. A developer's package is their castle, and they can generally manage it as they see fit. That freedom is somewhat constrained by the Debian constitution and the extensive Debian policy manual, both of which are designed to ensure that both developers and the packages they create all get along. Most of the time, this process just works, the project generates (mostly) regular releases, and users are happy. Occasionally, though, some sort of intervention is required; two of the mechanisms provided by the project for such cases are the Technical Committee and general resolutions. The Technical Committee is empowered to make decisions on technical policy and may, in extreme cases, override Debian developers if their actions are seen as sufficiently damaging to the distribution. General resolutions can, by way of a vote of the project membership, change or override decisions made by the Technical Committee (or others), set new policies, or amend the constitution. Voting is a key part of decision-making at levels above the individual developer. This is not particularly unusual in the free-software community; many projects make decisions by a vote of either the general membership or some sort of elected (via a vote, usually) representatives. Debian is nearly unique, though, in the way it decides what its members will vote on. Rather than simply being presented with a list of choices, Debian developers create those choices themselves, often in great number, and often with a lot of associated discussion. The creation of the ballot is the important part of a Debian resolution; the vote at the end is just calculating the final score. This process is designed to create outcomes that reflect, as well as possible, the will of the project as a whole. Debian's voting scheme allows a ballot to contain numerous options with small differences without fear of splitting the vote in a way that causes a relatively unpopular option to ultimately prevail. At its best, it creates ballots where developers can vote for the options they want rather than just voting against the worst case. Read more

Premium Open-Source WhatsApp Alternative “Threema” is Now Available for Desktop

Threema is one of the best secure alternatives to WhatsApp as a paid app (Swiss-based) that does not require a mobile number or email to sign up while using a decentralized architecture. While Threema is known for its security features long before WhatsApp advertised secure messaging, it wasn’t originally open-source. However, last year, Threema worked on making all of their applications open-source on GitHub with the ability to have reproducible builds as well. Now, it looks like Threema has introduced desktop application support for Linux, Windows, and macOS. Read more

  • How To Install Munin on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install Munin on Ubuntu 20.04 LTS. For those of you who didn’t know, Munin is a web-based tool to monitor system and network statistics. Munin shows this information through Graphs. It helps the system administrators to collect various system information that can be viewed via a web interface such as processor load, hard disk usage, network traffic, access to server services on one or more computers, and more. 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 Munin server monitoring on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

  • How to Install Yarn JS (Node) Package Manager on Debian 11 – VITUX

    Yarn is a package manager for Javascript. It is meant to replace npm (node package manager). Yarn uses a different way to install packages. Instead of installing from the registry, it installs packages from other nodes in your network that have already downloaded the package and its dependencies. This can speed up installations, especially in projects with lots of node modules. Yarn works exactly the same as npm, but with some benefits. First of all, it tells you which version of a package that was installed is compatible with your project. This makes it easier if you need to roll back or update packages. Secondly, it makes your packages more secure. Every package’s checksum is validated before it’s run by Yarn. This means that if a developer installs an outdated or corrupted package, Yarn will be able to detect the error, show the error in an easy-to-read format, and allow them to correct it before executing the code. It isn’t easy to say whether the yarn is better than npm or vice versa. It’s just different. If you want an easy-to-use package manager that makes your packages more secure, the yarn might be the answer. If you are a developer, chances are you have heard of Yarn. Installing yarn on Debian 11 can be tricky if you’re unfamiliar with the process, but this tutorial will walk you through the process step-by-step so that after reading this post, installing Yarn should be as easy as 1-2-3!

  • How to Record Your Desktop Screen in Ubuntu 21.10 Wayland with Kooha | UbuntuHandbook

    Looking for how to record Ubuntu desktop in Wayland session? Here’s how to do it in Ubuntu 21.10 using Kooha. Ubuntu switched to “Wayland” session since Ubuntu 21.04. However, many apps, e.g., Kazam, Peek and vokoscreen-NG, do not support it. Some apps including OBS-Studio claim to support for Wayland, but either record blank screen or just refuse to work! The best solution in my opinion is switch back to Xorg session. To do so, simply log out, select your user and then choose “Ubuntu on Xorg” via bottom-right gear button menu. All the apps will work once you login with Xorg. For those sticking to the default Wayland, Kooha is one of good choices until GNOME’s “in-shell” screenshot & screencast UI is out.

  • How to create an Application Load Balancer on AWS

    Load Balancer falls under the EC2 services of AWS. An Application Load Balancer works at the seventh layer of the Open Systems Interconnection (OSI) model, the application layer. We can add and remove targets from our load balancer as per our needs without affecting the flow of requests to the application. Application Load Balancer supports for path-based routing: forward requests based on the URL in the request, host-based routing: forward requests based on the host field in the HTTP header, routing based on fields in the request, registering targets by IP address: targets outside the VPC for the load balancer can also be added. These are a few of the benefits of using the Application Load Balancer.

  • How to edit files inside Docker container? - blackMORE Ops

    Just migrating everything to bunch of new RaspberryPi 4 8GB from my VMware farm. Instead of using multiple Raspberry Pi 4, I decided to use Docker and move as many I can into each one of these. I’ve think Home Assistant (with supervisor), Pi-Hole, Pi-VPN, UnBound and my NoIP2 scripts one Raspberry Pi4 8GB Pi running Debian 11 BullsEye and docker and Plex Server onto another Pi should do the trick. Anyhow, ran into an interesting problem with Undound where I needed to edit the configuration file nano application.yaml or vi unbound.sh and it said, nano or vi wasn’t installed.

  • Configuring TACACS+ Server With A Simple GUI | Linux Journal

    Managing authentication and authorization in a large-scale network is a challenge: the passwords need to be set and rotated every now and then, access to certain configuration settings needs to be controlled and, finally, users’ actions need to be logged somewhere. This poses a need for a centralized controller in the network that is responsible for such functions. Modern routers and switches, which typically run Linux operating systems, support TACACS+ protocol that enables system administrators to implement flexible rules for authentication and authorization. However, TACACS+ server implementation for Linux operating system, although neat, lacks a graphical user interface which makes daemon configuration a smooth and intuitive process. In the next few paragraphs, we will discuss how to configure the TACACS+ daemon on Linux operating system and demonstrate how to deploy a simple, yet intuitive, GUI used for the configuration of the TACACS+ instance. TACACS+, which stands for Terminal Access Controller Access-Control System Plus, is a protocol mainly designed by Cisco and standardized in RFC8907. The primary goal of the protocol is to handle authentication and authorization of commands executed on remote telecommunication hardware on a centralized server. TACACS+ is a great protocol and can be compared to RADIUS. Its key advantages are the following: it allows scrambling or obfuscating (although, not really encrypting in a cryptographic sense) the entire payload with help of MD5 hash function and a secret shared between telecommunication hardware and a central server, it supports TCP protocol for transport, and it provides the possibility of carrying out AAA functions in a flexible way. More details on the protocol can be found in the corresponding RFC.
