  • Who needs vinyl records when you’ve got Raspberry Pi and NFC?
  • UASP makes Raspberry Pi 4 disk IO 50% faster

    Without UASP, a drive is mounted as a Mass Storage Device using Bulk Only Transport (or BOT), a protocol that was designed for transferring files way back in the USB 'Full speed' days, when the fastest speed you could get was a whopping 12 Mbps!

    With USB 3.0, the BOT protocol cripples throughput. USB 3.0 has 5 Gbps of bandwidth, which is 400x more than USB 1.1. The old BOT protocol would transfer data in large chunks, and each chunk of data had to be delivered in order, without regard for buffering or multiple bits of data being able to transfer in parallel.

    So a new protocol was created, called 'USB Attached SCSI Protocol', or 'UASP'.

  • Xiaomi Mi TV Stick with Android TV Launched for as low as $29.99

    There’s been a fair amount of leaks related to Xiaomi Mi TV Stick around the web for the last few months, but the company has now finally launched their Android TV TV stick with a quad-core processor, 1GB RAM, and 8GB storage.

    While there were rumors about a 4K version, Xiaomi Mi TV Stick only outputs up to 1080p60, and since it runs the official Android TV OS, supports Chromecast and Google Assistant out of the box. Official Price: 39.99 Euros. But you can get it on Aliexpress for as low as $29.99 with coupon 715MITVSTICK.

  • ODROID-N2 Plus SBC Gets Amlogic S922X Rev. C Processor Clocked at up to 2.4 GHz

    Announced in February 2019, ODROID-N2 Amlogic S922X SBC launched the following month with 2GB to 4GB RAM, HDMI 2.0 output, Gigabit Ethernet, multiple USB 3.0 ports with pricing starting at $63 making very good value for an hexa-core Cortex-A73/A53 processor.

    The company has now announced an upgraded with ODROID-N2 Plus SBC featuring Amlogic S922X Rev.C bringing the Cortex-A73 big core maximum clock frequency from 1.8 GHz to 2.2GHz. But Hardkernel also found out they could overclock the processor up to 2.4 GHz in all 300 boards they have delivered a 33% boost over the original ODROID-N2 board. The Cortex-A53 cores are also a bit faster up to 2.0 GHz.

  • Lilbits: Computing convergence, another streaming platform, and DDR5

    It’s been 7 years since Canonical failed to raise meet its crowdfunding goals for the Ubuntu Edge smartphone that was supposed to be a phone you could also use as a desktop computer thanks to “convergence,” which is a fancy way of saying you could plug in a keyboard, mouse, and display and use it like a desktop computer.

    Over most of that time… not much happened on the convergence front. But now that companies including Pine64 and Purism are starting to ship phones designed to run Linux, convergence is a thing again.

    Today Pine64 announced a new PinePhone Convergence Pack that bundles a USB-C docking station with a PinePhone sporting slightly better-than-usual specs. Connect an external display and you can use it to run desktop apps.

Up to 2.4GHz Odroid-N2-Plus may be fastest open-spec Arm SBC

  • Up to 2.4GHz Odroid-N2-Plus may be fastest open-spec Arm SBC around

    Hardkernel has upgraded its Odroid-N2 SBC to an Odroid-N2-Plus with a new version of the hexa-core Amlogic S922X that boosts the 2x -A53 cores to 2.0GHz and the 4x -A73 cores to 2.2GHz, with overclocking up to 2.4GHz.

    Hardkernel has updated its high-end Odroid-N2 SBC with an Odroid-N2-Plus model that is likely the fastest community-backed Arm board on the planet. The Odroid-N2-Plus will probably beat out the more expensive Khadas Vim3 on all but AI benchmarks. The Linux-driven Odroid-N2-Plus moves to a faster RevC version of Amlogic’s S922X with improved CPU core power rail budget and higher clock frequencies.

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.
