  • Tonight's Game On OpenPOWER: Space Cadet Pinball

    Computer pinball, however, has been a mixed bag, largely because of the simulation fidelity necessary for good play. Nowadays you have Pinball Arcade on mobile devices and Visual Pinball on Windows, but for years the physics never really exceeded what you got in Bill Budge's 1982 Pinball Construction Set and table features were even more limited. The mid 1990s introduced probably the first generation of computer pinball games that actually played vaguely like real pinball and some real pinball tables were even ported (I played a credible if low-res version of Bally's Eight Ball Deluxe on my Mac).

  • Setting up a ThinkPad x250 with Linux

    Two chapters in this article are Debian-specific, the rest is more or less Archlinux-specific. It never grew into the device-specific alround tutorial I envisioned and has been partially superseded by this article. The ThinkPad itself is in daily use. No regrets there!

  • 40% users blame manufacturers for security of their IoT devices

    Nearly 88 per cent of users who surveyed own some kind of IoT device in their household.

    Almost half of them put the responsibility for the security of those devices on manufacturers and therefore do nothing to protect them, according to research by NordVPN, a leading virtual private network (VPN) service provider.

  • Reverse engineering a thermal printer's WiFi setup commands

    Since booting into Windows every time I want to manage the printer's network settings isn't ideal, I decided to reverse engineer the WiFi configuration commands.

  • Sequoia PGP Is Now LGPL 2.0+

    When we started Sequoia, we choose to license the code under the GPL 2+. One reason that we chose the GPL is that it makes a political statement: we support free software.

    Over the past four years, however, several free software projects have chosen not to use Sequoia, because it is under the GPL. Delta Chat planned an iOS app, but because Apple does not allow GPL software in their App store, the Delta Chat developers couldn’t use Sequoia. And, when Thunderbird looked for a new OpenPGP library, they rejected Sequoia because it was licensed under the GPL. These are the two most prominent examples of free software projects rejecting Sequoia. Unfortunately, there are others.

  • The Javascript "ecosystem" is a hot mess and so is software development in general

    Maybe a bit dramatically, one is forced to think that all of this complexity, bloat, and hot new bloat to fix previous bloat, is a net loss for humanity. If quantified, the cost in terms of time, effort, energy, and money must be enormous. What a collective, mammoth exercise in intellectual dishonesty. What a monumental waste.

  • Features of Excellent Code Review Tools

    Last week, I onboarded onto a new code review system. In learning how to review code in this new tool, I got to thinking about best features of previous code review systems I’ve used. What follows is an opinionated (and very incomplete) list of what I think are “table stakes” for code review in 2021.

    For the purposes of this post, “code review tool” refers to a web UI for reviewing code – think Github, Gitlab, BitBucket, Gerrit, Phabricator’s Differential, and Azure Devops. This list is agnostic to the choice of the underlying SCM (e.g. git, mercurial, perforce, etc.), so I refer to diffs, PRs, and CLs interchangeably.1

  • Non-blocking shell-input

    There are solutions on the Web.

    Having read some of these, I prefer a Ruby-Onliner which returns the 1 character that the user has had a chance to enter on the keyboard, before readNB returns.

  • British Telecoms Are Aligning with Emerging U.S. Position on Open RAN Adoption

    Speaking at the opening session titled “Building an innovative converged network infrastructure for the UK,” Watson discussed the challenges and possibilities for offering fast, secure broadband and offered O-RAN as a solution for wider connectivity.

    Watson discussed utilizing open RAN to facilitate greater interoperability between vendors’ equipment, as it opens the market to more technologies due to its open configuration. The concept advocates for a more open radio access network than provided today, which is held by fewer vendors.

  • Open and Transparent Way towards Open RAN by the O-RAN ALLIANCE

    O-RAN ALLIANCE was founded by 5 major operators: AT&T, China Mobile, Deutsche Telekom, NTT DOCOMO and Orange. In three years, the O-RAN ALLIANCE has grown to a world-wide community of more than 300 operators, vendors and research and academic institutions jointly developing a sustainable O-RAN ecosystem. The 30 Mobile Network Operators in O-RAN serve over 4,5 Billion subscribers around the world.

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.
