  • In practice, Debian (and Ubuntu) have fixed minimum system UIDs and GIDs

    Unfortunately, in practice the start of the range for both system UIDs and GIDs is fixed. This comes about through two things combined together. First, a certain number of system logins and groups are created early in system installation, well before you can normally customize the system. These early system logins and groups will use the standard starting point for system UIDs and GIDs (currently 100 for both), and so be assigned low UIDs and GIDs. This includes things like the 'systemd-network' login and the 'systemd-journal' group.

  • Open source developer corrupts widely-used libraries, affecting tons of projects

    A developer appears to have purposefully corrupted a pair of open-source libraries on GitHub and software registry npm — “faker.js” and “colors.js” — that thousands of users depend on, rendering any project that contains these libraries useless, as reported by Bleeping Computer. While it looks like color.js has been updated to a working version, faker.js still appears to be affected, but the issue can be worked around by downgrading to a previous version (5.5.3).

  • Blockchain and how does it work?

    In his 1982 dissertation “Computer Systems Established, Maintained, and Trusted by Mutually Suspicious Groups,” cryptographer David Chaum presented a blockchain-like system for the first time. Stuart Haber and W. Scott Stornetta presented more work on a cryptographically protected chain of blocks in 1991.

    However, blockchain saw its use in 2009.

    Satoshi Nakamoto created the first successful and popular implementation of Blockchain technology in 2009 by creating the first digital cryptocurrency called Bitcoin.

  • Dirk Eddelbuettel: Rblpapi 0.3.13: Some Fixes and Documentation

    A new version, now at 0.3.13, of the Rblpapi package just arrived at CRAN. Rblpapi provides a direct interface between R and the Bloomberg Terminal via the C++ API provided by Bloomberg (but note that a valid Bloomberg license and installation is required).

    This is the thirteenth release since the package first appeared on CRAN in 2016. It comprises the PRs from three different contributors (with special thanks once again to Michael Kerber), and extends test and documentation, and extends two function interfaces to control explicitly whether returned lists of length one should be simplified.

  • Security updates for Monday [LWN.net]

    Security updates have been issued by Debian (ghostscript and roundcube), Fedora (gegl04, mbedtls, and mediawiki), openSUSE (kubevirt, virt-api-container, virt-controller-container, virt-handler-container, virt-launcher-container, virt-operator-container), SUSE (kubevirt, virt-api-container, virt-controller-container, virt-handler-container, virt-launcher-container, virt-operator-container and libvirt), and Ubuntu (apache2).

  • Josh Bressers: Episode 305 – Norton, Ethereum, NFT, and Apes

    Josh and Kurt talk about Norton creating an Ethereum mining pool. This is almost certainly a bad idea, we explain why. We then discuss the reality of NFTs and the case of stolen apes. NFTs can be very confusing. The whole world of cryptocurrency is very confusing for normal people. None of this is new, there have always been con artists, there will always be con artists.

  • The Story of Adobe

    Adobe is celebrating its 40th anniversary this year and the company has never been performing better. After successfully moving from the perpetual licensing model of software to SaaS, the company is worth $243 billion. Many of the products that made Adobe famous are still used today like PDF and Photoshop. Adobe's story is fascinating: run ins with Steve Jobs, snagging a distribution deal of a hot new piece of software called Photoshop, and even a kidnapping.

  • 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.
