Pinephone Multiboot Image Boots 13 Different Linux Distributions

Pinephone Multiboot 13 Linux distributions

You’ve certainly heard about dual-boot systems with Windows and Linux, and possibly about triple-boot systems with an extra OS like Chromium OS or Android, but pine64’s forum user Megous has gone much further with a multiboot image for Pinephone able to boot 13 different Linux distributions! You’d think the image would occupy a lot of space on the device, but since all 13 distributions share the same Linux 5.9 kernel, all 13 operating systems fit on the internal eMMC flash or a MicroSD card with 8GB or greater capacity. The image is based on the p-boot bootloader allowing you to select the distribution of your choice and supports all PinePhones from the Braveheart Edition to the most recent revisions with 3GB RAM and 32GB storage. So what Linux distributions are supported by the multiboot image exactly? Here’s the list: Arch Linux Arm 2020-09-08 Lune OS 0.113 Maemo Leste 20200906 Mobian […]

No password SSH – Login to a SSH server with private/public keys

If you often need to establish SSH connections to a server, entering the password each time may be a hassle or even a non-starter. For example, in our case, we use ssh connections in our nightly build scripts, so obviously entering a password would not be an option here… So it can be useful to configure the server and your client to accept secure ssh connection without the need to enter a password. What must be done, then, is to generate a public/private key pair, and copy the public part into the appropriate place on the server side. For doing this, on the user’s home directory, on the client machine, type:

local> ssh-keygen -t rsa -f ~/.ssh/id_rsa

1	local> ssh-keygen -t rsa -f ~/.ssh/id_rsa

-t tells the type of encryption -f tells where to store the public/private key pairs. In this case, the .ssh directory in the home directory is being used A password will be asked; leave this part blank, just […]

SiFive to Debut RISC-V PC for Developers based on Freedom U740 next-gen SoC

In recent years, people have discussed the need to have Arm-based PCs or workstations for developers to work directly on the target hardware, and there are now several options including SynQuacer E-Series 24-Core Arm PC, Ampere eMAG 64bit Arm Workstation, and HoneyComb LX2K 16-core Arm Workstation. Now it appears we’ll soon get something similar for RISC-V architecture with SiFive to debut the first RISC-V PC for developers at the Linley Fall Processor Conference 2020 taking place on October 20-22 and October 27-29. The PC will be powered by Freedom U740 next-generation RISC-V processor that will also be introduced at the event. We have very few details about this point in time, but the company points the SiFive Freedom U740 (FU740) SoC will enable professional developers to create RISC-V applications from bare-metal to Linux-based. The processor is said to combines a heterogeneous mix+match core complex with modern PC expansion capabilities, which […]

I’ve previously written about Intel’s (relatively) new NUC 9 range of mini PCs and now I am following up with my experiences of having bought one. Whilst I’ll cover some performance metrics from both Windows and Ubuntu I’ll also discuss the benefits and drawbacks of using either OS together with a comparison of gaming, thermals, and power usage as well as a brief look at overclocking potential and implications together with highlighting the issues encountered. NUC9i9QNX Hardware Overview The model I purchased and will be reviewing here is the NUC9i9QNX from Intel’s Ghost Canyon lineup and is formally known as the Intel NUC 9 Extreme Kit – NUC9i9QNX. It contains a “Compute Element” with an i9-9980HK which is an eight-core 16-thread 2.40 GHz processor boosting to 5.00 GHz with Intel’s UHD Graphics 630. The full specifications of the NUC9i9QNX include: The NUC9i9QNX is sold as a kit which essentially means […]

HarmonyOS 2.0 Beta Released, HarmonyOS Devices Coming in 2021

Due to geopolitical tensions, Huawei cannot rely on Google Android operating system over the long term, and in May 2019 we reported HongMeng OS may become Huawei’s OS alternative to Android. HongMeng (鸿蒙) OS will finally be called HarmonyOS outside of China, and we recently reported Huawei was trying to attract more developers with monetary incentives to brings more apps to HMS (Huawei Mobile Services). We now have a more clear timeline with the company’s recent release of HarmonyOS 2.0 beta that’s currently available for smart home applications, smartwatches, and head-on-displays, and will become available for smartphones in December 2020. The release includes SDKs with over 13,000 APIs, documentation, tools, and simulator/emulator. OpenArk is an open-source compiler that was released last September, and Huawei DevEco is the IDE for development that works on top of Android Studio. Huawei also introduced OpenHarmony which should be the equivalent of the Android Open […]
