Raspberry Pi 4 as Desktop Computer: Is It Really Viable?

Filed under
GNU

Hardware

There’s little doubt that the Raspberry Pi 4 is significantly more powerful than its predecessors. Its based on the faster ARM Cortex-A72 microarchitecture and has four cores pegged at marginally-higher clock speeds. The graphics subsystem is significantly beefed up as well, running at twice the maximum stock clocks as the outgoing model. Everything about it makes it a viable desktop replacement. But is it really good enough to replace your trusty old desktop? I spent three weeks with the 8GB version of the Pi 4 to answer that million-dollar question.

  • Making a random sound diffuser with Arduino

    Humans are generally quite bad at coming up with random patterns, so when Jeremy Cook wanted to make a sound diffuser with angled blocks of wood, he created a “pseudorandomness console” using an Arduino Uno and an LCD shield.

    [...]

    Code for this unique randomization is available on GitHub, with a quick explanation in the video above. You can see the final assembly at around the 4:38 mark, showing a process of applying glue, pressing a button to generate a value, and then placing triangles accordingly.

  • Marcin 'hrw' Juszkiewicz: 8 years of my work on AArch64

    Back in 2012 AArch64 was something new, unknown yet. There was no toolchain support (so no gcc, binutils or glibc). And I got assigned to get some stuff running around it.

    [...]

    First we had nothing. Then I added AArch64 target into OpenEmbedded.

    Same month Arm released Foundation model so anyone was able to play with AArch64 system. No screen, just storage, serial and network but it was enough for some to even start building whole distributions like Debian, Fedora, OpenSUSE, Ubuntu.

    At that moment several patches were shared by all distributions as it was faster way than waiting for upstreams. I saw multiple versions of some of them during my journey of fixing packages in some distributions.

  • Intel's 10nm Elkhart Lake Atom chips feature Cortex-M7 and triple 4K

    Software support includes Yocto Project, Ubuntu, Wind River Linux LTS, Android 10, and Windows 10 IoT Enterprise. There is also support for Intel’s OpenVINO toolkit, with pre-optimized libraries for AI, ML, and computer vision acceleration.

  • Intel Unveils Atom x6000E Series, Celeron and Pentium Elkhart Lake IoT Edge Processors

    We’ve been expecting Intel Elkhart Lake processors for more than a year, and the company has now officially announced the “IoT-enhanced processors” with a new Atom x6000E Series, as well as some Celeron and Pentium N/J parts. Last year, we thought Elkhart Lake would succeed Gemini lake, but the new 11th generation 10nm processors may not be found in many consumer devices, as they target IoT edge applications with additional artificial intelligence (AI), security, functional safety, and real-time capabilities.

RISC-V is definitely getting a lot of traction in the microcontroller space, and even Arm is trying to make it easier for other companies to adopt that adopt their baseline designs. Arm and ARC are definitely competitors, especially in the IoT embedded space.

Librem 14 Shipping in December

The Librem 14 is going to be a powerhouse with a six core, twelve thread, 4.70Ghz i7-10710U tenth generation Intel CPU. When we first announced the Librem 14 pre-order, we estimated shipping would begin in early Q4 2020 but unfortunately Intel has industry-wide supply issues with the i7-10th gen CPUs which has moved the ship date for the Librem 14 to December 2020.

That’s the bad news. The good news is that the current $100 pre-order sale will continue for a bit longer. We also hope to finish some fresh Librem 14 prototypes in about a week, so we can share new pictures of the design.

  • Convert an old cassette player into a synthesizer

    Cassettes (if you remember those) are normally used to play back music and other audio, but what about using an old Walkman-style tape player as the instrument itself? That’s exactly what this project by Zack Scholl allows you to do, varying the playback speed to modify pitch output.

    It’s a very simple setup, requiring one to hook up wires that enable an Arduino Uno and MCP4725 DAC to adjust the speed using a voltage input. A drone sound is recorded on the tape, which may also involve some hacking depending on your equipment.

  • Making a 3D graphics video for the Librem 5

    At Purism, we do all our videos and other promotional material internally, with Librem hardware and free software only. This is part of our policy and I think it’s important, when I believe in something, to act in accordance with it.

    A few days after releasing the video of the Librem 5 hardware design, I was asked by a few people to publish an article describing the process of making this video.

    In early 2019, we shot a funny commercial for Librem One and I made a blog post, along with a video, to explain the process of making this kind of commercial with Librem hardware and free software. I was not going to do a “behind the scenes” blog post again but the Librem 5 video is entirely made with 3D graphics and the workflow is quite different so I think that it is interesting to describe that process in a new post.

  • AMD Enables Ryzen in Chromebooks, Improving Performance

    A modern enthusiast will scoff at the concept of a Chromebook – limited performance, capabilities, and a simplistic OS for doing some serious work? The fact is that the Chromebook, and Chrome OS, have been gazumping good portions of the notebook market share in recent years, mostly down to its stripped down nature but also the low pricing. In 2019 AMD relaunched its older A-series APUs for Chromebooks, meeting that market need. However, at CES this year we saw the first indication of premium $700+ Chromebooks from Intel. Now AMD is moving into a higher performance space with its Chromebook offerings with new optimized Ryzen hardware and Vega graphics.

    [...]

    AMD claims to have a 21% market share in the Chromebook space, using IDC data, and Chromebooks currently account for 18% of all notebook sales. The market is largely split into three categories: education, enterprise, and consumer, with education seeing a big uplift in recent months due to the pandemic. Also because of the pandemic, as well as the growth of Chromebooks as a viable tool for these markets, use-cases are expanding with new productivity applications becoming available as well as the need to drive multiple high resolution displays.

  • AMD Announces Ryzen/Athlon 3000 C-Series For Chromebooks

    AMD announced these 3000 C-Series mobile processors as the first Zen optimized Chromebook processors with Acer, ASUS, HP, and Lenovo all committing to releasing AMD Chromebooks in Q4'2020.

    Compared to the previous-generation AMD A-Series "Excavator" APUs in Chromebooks, AMD is promoting up to 251% better graphics performance, up to 104% faster productivity, and up to 152% better photo editing with these new Zen C-Series processors.

  • OnLogic’s Ubuntu-ready AMD servers include compact industrial edge model

    OnLogic has launched a line of AMD servers, including two with 2nd Gen Epyc and three with Ryzen 3000, including a $1,547 and up Compact Industrial AMD Ryzen Edge Server. Meanwhile, AMD launched some 15W mobile Ryzen C-series chips.

    OnLogic and AMD, which last year teamed up on promoting OnLogic mini-PCs based on AMD’s Ryzen Embedded V1000 and R1000 SoCs, are now collaborating on OnLogic’s new lineup of servers based on 2nd Gen Epyc and AMD Ryzen 3000 processors. Most of these are rackmount servers that are beyond our typical product coverage, but we are intrigued by the desktop form-factor Compact Industrial AMD Ryzen Edge Server (MC850-40), which blurs the line with the high-end embedded edge servers.

    [...]

    AMD’s Eypc Embedded SoCs are scaled down versions of the 2nd Gen Epyc SoCs used by OnLogic’s new rackmount systems: the 2U, $2,887 and up MK200-60 and 4U, $5,051 and up MK400-60. These “Eypc Edge Servers” tap the Epyc Rome 7002 in up to 32- and 64-core configurations, respectively, with up to 256GB RAM.

Manage knowledge with BlueSpice, an open source alternative to Confluence

Knowledge management is a key to success in modern enterprises—but it is not exactly easy to achieve. Keeping track of all relevant details across all employees is a huge challenge, especially in agile environments, which most companies say they are. Most companies resort to buying wiki-like solutions, such as Confluence from Atlassian, which exposes them to the lock-in effect of proprietary software. But many would do well to consider BlueSpice, an open source alternative to Atlassian Confluence that has a noble ancestry: it's based on Wikipedia's MediaWiki. Read more
