  • Old Portable TV Becomes Unique CRT Cyberdeck | Hackaday

    Remember the “suitcase” form-factor for PCs? In the time before latops, these luggable machines were just the thing for the on-the-go executive. OK, maybe not really — but the ability to have PC, monitor, and peripherals in a single package had real appeal, and a lot of that rationale is behind the cyberdeck phenomenon. So when we saw this retro portable TV turned into a cyberdeck, it really caught our eye.

    Ironically, the portable black-and-white TV that [Lucas Dul] chose as the basis for his cyberdeck hails from about the same period in time that luggable PCs were having their brief time in the sun. Scored from eBay, the Magnavox TV/radio combo had seen better days, and required a bit of surgery to repair what might have been drop damage. With the CRT restored and the video and audio paths located, the TV got a Raspberry Pi, a small touchpad, and a couple of concealed USB connectors. The Pi’s composite output drives the CRT, with about the results you’d expect. The keyboard appears to be just about the right size to serve as a cover, but [Lucas] said that’s a future project.

  • Linux Mint apparently runs better than Windows 11 on Surface devices [Ed: But why would you want to pay Microsoft for hardware (that it does not even produce) and for a Windows licence you neither want nor use?]

    No, it isn’t a joke, people took it upon themselves to try it and the results are actually better than what was initially expected from this experiment.

    Furthermore, users that have been using Surface devices since for graphics and work state that there is always something wrong with them.

    They are referring to either Windows OS-specific problems or questionable hardware configurations choices made by Microsoft.

    Regardless of the motivation that drove some to leave Windows 11 behind in favor of Linux, on Microsoft-designed laptops and tablets, the result is the same.

Hardware

In any given field there are epoch-defining moments, those events after which nothing was quite the same as it had been before. It’s been a decade since the launch of the first Raspberry Pi single board computer. This was by no means the first inexpensive computer board, nor was it the first to support the GNU/Linux operating system, but it was among the first to promise a combination of those two. Coupled with support from a crop of British 8-bit alumni meant that from when it first gained publicity in early 2011 it garnered a huge buildup of interest.

We were first teased with a USB stick style prototype, which morphed into a much larger Raspberry Pi alpha board and finally into pre-production boards much closer to the model launched at the end of February ten years ago.

  • Greece about to secure Router Freedom but leaves fiber out

    Greece is one step closer to securing Router Freedom, but regulators are excluding fiber (FTTH) connections from the legislation. A coalition of organisations, allies of the FSFE, is now requesting that lawmakers reconsider this and thus safeguard the freedom of all users. Since 2021, the regulatory process that defines the network termination point (the NTP) in Greece has been carried out by the Hellenic Telecommunications and Post Commission (EETT). Defining the NTP is necessary to determine whether users have the right to choose their own router and modem or if their Internet Service Providers (ISPs) have the final say over network equipment. In April 2022, we welcomed that the Greek regulator proposed legislation safeguarding Router Freedom for common networks, such as DSL and coaxial. This is a leap forward in safeguarding consumer rights. However, in the same proposal, EETT has explicitly excluded fiber connections (FTTH), a decision that has the potential of negatively impacting end-users’ rights. The proposed regulation sets the NTP for fiber connections in a position that would make the optical terminal equipment part of the ISPs’ networks, making home network access equipment the property of the ISP. The FSFE assisted a coalition of organisations to respond to the EETT’s public consultation, supporting the regulator to implement Router Freedom for all types of internet connection, including FTTH.

  • Notes on running containers with bubblewrap

    Hello! About a year ago I got mad about Docker container startup time. This was because I was building an nginx playground where I was starting a new “container” on every HTTP request, and so for it to feel reasonably snappy, nginx needed to start quickly. Also, I was running this project on a pretty small cloud machine (256MB RAM), a small CPU, so I really wanted to avoid unnecessary overhead. I’ve been looking for a way to run containers faster since then, but I couldn’t find one until last week when I discovered bubblewrap!! It’s very fast and I think it’s super cool, but I also ran into a bunch of fun problems that I wanted to write down for my future self.

  • Fix: Why Isn’t Linux Detecting My Wi-Fi Adapter?

    Historically, Linux has had a somewhat strained relationship with Wi-Fi cards. In recent years, the situation has changed considerably—and for the better—but it is still possible to boot into your new Linux installation and get that sinking feeling when you realize you’ve got no Wi-Fi. Installation routines are very good at identifying the various components of the target computer and configuring itself to work with that hardware. But problems can still happen. Troubleshooting hardware issues is difficult, especially if the only computer you have on hand is the broken device. Obviously, not everything presented here will be applicable to all cases. But hopefully, something below will either fix your issue or point you in the right direction.

  • Open-sourced tool speeds up Linux scripts via parallelization | Network World

    MIT has open-sourced pa.sh (also called pash), a tool that can dramatically speed up Linux scripts by using parallelization, saving time and without risk of introducing errors. The process of parallelization first examines a script for code that can be run separately and independently, so not all scripts can benefit from the tool. But when pa.sh does find portions that can run independently, it runs them in parallel on separate CPUs. It also uses other techniques to get the code to run faster. Below is a demonstration I ran on my home Fedora box, first running a script on its own and then again using pa.sh. Note that this script was provided with the pa.sh tool and lends itself to parallelization. It’s not nearly as demanding as scripts that might process gigabytes of data in a scientific or artificial-intelligence lab, so the results are not dramatic.

    Continuous integration/continuous delivery (CI/CD) principles offer multiple benefits to software organizations, including faster time to market, higher-quality code, and simpler and faster fault isolation. Applications built using CI/CD pipeline best practices tend to see a huge increase in users over time, necessitating a migration from a large codebase and low-scalability monolithic architecture to a more manageable and efficient microservice architecture. Kubernetes is one of the most popular platforms for automating the management, deployment, and scaling processes of microservice applications. Because Kubernetes is complex, though, a framework can help developers and operations teams use the platform to follow CI/CD practices in building applications. This is where Tekton comes in.
