  • Pine64 Announce Rockchip RK3588 Powered QuartzPro64 Development Board | Tom's Hardware

    Pine64’s announcement also delved into the vexed issue of pricing, with the board likely to retail “north of $300”, putting it out of Raspberry Pi competitor territory. The manufacturer hasn’t yet settled on a price-point, but it is likely to be sold at cost or even subsidized. “Here’s the take-away,” the announcement concludes. “This is an amazing platform, but it will take time for it to mature.”

  • Russell Coker: More About the Librem 5

    I concluded my previous post about the Purism Librem 5 [1] with the phone working as a Debian/GNOME system with SSH access over the LAN. Before I published that post I managed to render it unbootable, making a new computer unbootable on the first day of owning it isn’t uncommon for me. In this case I tried to get SE Linux running on it and changing the kernel commandline parameter “security=apparmor” to “security=selinux” caused it to fail the checksum on kernel parameters and halt the boot. That seems to require a fresh install, it seems possible that I could setup my Librem5 to boot a recovery image from a SD card in such situations but that doesn’t seem to be well documented and I didn’t have any important data to lose. If I do figure out how to recover data by booting from a micro SD card I’ll document it.

    Here’s the documentation for reflashing the phone [2], you have to use the “--variant luks” option for the flashing tool to have an encrypted root filesystem (should default to on to match the default shipping configuration). There is an option --skip-cleanup to allow you to use the same image multiple times, but that probably isn’t useful. The image that is available for download today has the latest kernel update that I installed yesterday so it seems that they quickly update the image which makes it convenient to get the latest (dpkg is slow on low power ARM systems). Overall the flash tool is nicely written, does the download and install and instructs you how to get the phone in flashing mode. It is a minor annoyance that the battery has to be removed as part of the flashing process, I will probably end up flashing my phone more often than I want to take the back off the case. A mitigating factor is that the back is well designed and doesn’t appear prone to having it’s plastic tabs breaking off when removed (as has happened to several other phones I’ve owned).

  • Java News Roundup: JDK 19 and Jakarta EE 10 Updates, Ansynch and Buffered Logging by Amazon Corretto

    JEP 422, Linux/RISC-V Port, has been promoted from Candidate to Proposed to Target for JDK 19. This JEP proposes to port the JDK to Linux/RISC-V, a free and open-source RISC instruction set architecture. The template interpreter, C1 and C2 JIT compilers, and all current mainline GCs, including ZGC and Shenandoah, will be supported. The main focus of this JEP is to integrate the port into the JDK main-line repository. The review is scheduled to conclude on March 17, 2022.

  • 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.
