Open Source Operating Systems News – Maru OS, Zephyr, ReactOS, Tizen 3.0, and Raspbian

There have been several news related to open source operating systems in the last couple of weeks including Maru OS to run Debian on Android, Zephyr Project real-time OS managed by the Linux Foundation, ReactOS an open source port of Windows XP, and Raspberry Pi boards are getting a Tizen 3.0 port, as well as a new Raspbian release. Maru OS – Mobile <-> Desktop  Convergence Maru OS mobile operating system is supposed to do what Ubuntu convergence promised: it runs in mobile mode on the go with Android Lollipop mobile OS, once you connect the phone to an HDMI screen, and pair Bluetooth keyboard and/or mouse, it will switch to desktop mode running Debian Linux. The downside is that so far it a single developer (Preetam D’Souza) worked on it, and the beta version only works on Nexus 5 smartphone. However, since the project went viral, dozen of other […]

NexDock is a 14″ Lapdock Alternative for mini PCs, Development Boards, Smartphones and Tablets (Crowdfunding)

Motorola once launched the Lapdock, a device that looks like a laptop with a 11.6″ screen and a keyboard, but without processor or memory since it was instead designed to connect to the company’s Atrix 4G smartphone. Motorola eventually pulled the plug on this concept, and maybe it was just ahead of its time, as a startup has now developed NexDock, a device similar to Lapdock with a 14″ display, built-in battery and Bluetooth keyboard. NexDock technical specifications: Display – 14.1″ TN screen; 1366×768 resolution; 16:9 display ratio Bluetooth 4.0 keyboard and touchpad Video input – mini HDMI port Audio Output – 3.5mm headphone port Storage – micro SD card slot USB – 2x USB ports Battery – 3.8V / 10000mAh Li-ion battery Power – 5V/2.5A via 3.5mm power barrel Dimensions – 351 mm x 233 mm x 20 mm Weight – 1490 grams NexDock is operating system agnostic and would […]

How to Check CPU Throttling in Windows 10 or Windows 11

Recent processors all have the ability to adjust the operating frequency to either decrease power consumption or make sure the processor does not overheat. That’s why for example Intel processors have a maximum junction temperature (Tj max) so that if this temperature is reached the processor can slow down (throttle) to cool things off and avoid damaging itself. That also explains why computers with the same processor, storage, and memory may have greatly different performance under load depending on their thermal design. I’m currently testing a fanless mini PC with an Intel Celeron N3150 Braswell processor, and yesterday I noticed the frequency would be stuck at 0.22 GHZ (yes, that’s 220 MHz) at all times, even when starting the web browser and loading long web pages. It was very slow, and I had a few “windows not responding” in the process. I checked the metal box temperature with an IR […]

Rhombus Tech 15.6″ Libre Laptop is User-Upgradeable with EOMA68 CPU Cards

When the first Raspberry Pi model launched, there was just not enough boards to fill the demand, and as people kept waiting they were also investigating alternatives, and a growing community worked on Allwinner based platforms. At the time (2012), the main hardware project  was EOMA68 CPU card using a PCMCIA connector, with ended up inside Improv development board, and aimed at providing user replaceable and upgradeable CPU cards. Sadly the initiative got some issues, and things did not quite work out as expected, but the person who launched the whole project, Luke Kenneth Casson Leighton (LKCL), did not give up on the idea, and has kept on working on EOMA68 standard with CPU cards from Allwinner and other SoC vendors. Recently, he’s been working on a Libre Laptop based on an Allwinner A20 EOMA68 CPU module, and will showcase the prototype at FOSDEM 2016 in Brussels this coming week-end. […]
