  • Security updates for Tuesday

    Security updates have been issued by Debian (ksh), openSUSE (ant, chromium, ldb, samba, and LibVNCServer), Red Hat (dbus, kernel, kernel-rt, and NetworkManager), and SUSE (cni-plugins, firefox, openexr, Salt, salt, SUSE Manager Client Tools, and tomcat).

  • Update your Google Chrome browser now to avoid hackers, says CERT-In

    The government's cybersecurity agency has warned Google Chrome users in the country to immediately upgrade to the new Chrome browser version to avoid remote hackers from intruding into their machines.

    Google has released Chrome 84.0.4147.89 upgrade that contains 38 fixes and improvements against vulnerabilities.

    "Multiple vulnerabilities have been reported in Google Chrome that could allow remote attacker to execute arbitrary code, bypass security restrictions, access sensitive information, contact spoofing attack and denial of service (DoS) attack on the targeted system," the Computer Emergency Response Team-India (CERT-In) warned in its latest advisory.

  • State-of-the-art crypto goes post-quantum

    Secrecy is one of the most important functions of computer science. Should electronic secrecy suddenly collapse into total transparency, we could not engage in electronic commerce, we would be unable to communicate privately, our past communications would be globally visible, and we would be critically impacted in myriad ways that would fundamentally change our ability to work and live. Consider the time we spend every day maintaining our secrecy with passwords, lock patterns, wireless fobs, and biometrics that restrict access to protect us and the ramifications of their failure.

    Public-key cryptosystems form a critical aspect of our secrecy. The ability to establish private communications over a public medium is exercised billions of times per day. Should technology arise that unmasks this private discourse, the consequences could be incalculable.

    In quantum computing, such a technology is rising. Potential hardware that can execute Shor's algorithm to directly threaten commonly used public-key schemes (RSA, conventional Diffie-Hellman, and elliptic curve) may be far nearer to realization than we would expect. D-Wave corporation has promised to deliver an adiabatic quantum computer this year with 5,000 qubits; this machine is not capable of directly running Shor's algorithm, but if it were, TLS and SSH would be severely compromised. There is some urgency to correct our cryptosystems.

  • 5 Open-Source Blockchain Technologies That Linux Users Need to Know About

    As such, it only makes sense that developers explore blockchain use within the Linux environment. In this article, we delve into five open-source blockchain technologies for Linux. But first, let’s examine what blockchain is and how this technology works, and take a look at how the application of blockchain has evolved over the years.

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.
