  • Putting the Open back into Open Source

    Agility has never been more important than it is in today’s disrupted digital world. Leaders in every industry are trying to find a balance between the stability that allows them to plan for the future, while creating highly agile organisations that can quickly respond to new challenges and opportunities.

    This agility only comes from the ability to innovate at speed, which is why open source communities are as vital as ever. According to SUSE’s recently commissioned Insight Avenue report, Why Today’s IT Leaders are Choosing Open, 84% now see open source as a way to cost-effectively drive this innovation.

  • How To Install Snap on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install Snap on Ubuntu 20.04 LTS. For those of you who didn’t know, Snap also known as Snappy is an alternative package management tool and program package format developed by Canonical, the company behind Ubuntu Linux. All the snaps are usually stored in a central repository called Snap Store from where snaps can be downloaded and installed using the snap command. Snaps work across a range of Linux distributions, which makes them a distro-agnostic upstream software deployment solution.

    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 Snap Package Manager 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.

  • Unboxing Busybox: Claroty and JFrog uncovers 14 vulnerabilities

    Embedded devices with limited memory and storage resources are likely to leverage a tool such as BusyBox, which is marketed as the Swiss Army Knife of embedded Linux. BusyBox is a software suite of Unix utilities, known as applets, that are packaged as a single executable file.

    Within BusyBox you can find a full-fledged shell, a DHCP client/server, and small utilities such as cp, ls, grep, and others. You’re also likely to find many OT and IoT devices running BusyBox, including popular programmable logic controllers (PLCs), human-machine interfaces (HMIs), and remote terminal units (RTUs)—many of which now run on Linux.

    As part of our commitment to improving open-source software security, Claroty’s Team82 and JFrog collaborated on a vulnerability research project examining BusyBox. Using static and dynamic techniques, Claroty’s Team82 and JFrog discovered 14 vulnerabilities affecting the latest version of BusyBox.

    In most cases, the expected impact of these issues is denial of service (DoS). However, in rarer cases, these issues can also lead to information leaks and possibly remote code execution.

  • Perl Weekly Challenge 140: Multiplication Tables
  • Leaky Rakudo

    Yesterday the discord-bridge-bot refused to perform its 2nd job: EVAL All The Things! The EVALing is done via shell-out and requires a fair bit of RAM (Rakudo is equally slim then Santa). After about 3 weeks the fairly simple bot had grown from about halve a GB to one and a halve – while mostly waiting for the intertubes to deliver small pieces of text. I complained on IRC and was advised to take heap snapshots. Since I didn’t know how to make heaps of snapshots, I had to take timo’s directions towards use Telemetry. As snap(:heap) wasn’t willing to surrender the filename of the snapshot (I want to compress the file, it is going to get big over time) I had a look at the source. I also requested a change to Rakudo so I don’t have to hunt down the filename, which was fulfilled by lizmat 22 minutes later. Since you may not have a very recent Rakudo, the following snipped might be useful.

  • Nemiver debugger now in devx SFS

    Mike (mikewalsh) responded with a great link that lists lots of Linux debugger/trace tools. The EasyOS devx SFS already has the 'gdb' CLI utility, and I saw on that link, there are 'ddd' and 'nemiver' GUI frontends for gdb.
    I went for nemiver and compiled it. The project seems to be almost dead, but then, if it works, perhaps no need for more commits to the git repository. I chose version 0.8.2, not the latest, but it suited me to stay with a gtk+2 based app rather than gtk+3.
    Two dependencies, 'gtkmm' and 'libgtop', are compiled in OpenEmbedded. I compiled 'libgtksourceviewmm' and 'nemiver' in a running EasyOS and made them into PETs.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
