Acer Aspire 3 A315-41G (AMD Ryzen 7 2700U) Laptop – Installing Ubuntu 18.04 and “Hidden” M.2 SSD Socket

Everyday I’m using a tower PC running Ubuntu 18.04 to take care of this blog, but when I travel it’s obviously not so convenient, so a few years ago I bought an Acer Aspire E5-421G laptop powered by an AMD A4-6210 processor with 4GB RAM, 512GB HDD, and a 14″ display. I installed Ubuntu on the laptop and it works, but with 4GB RAM, it’s not always usable while multitasking. For example I can run Thunderbird and Firefox, but if I ever make a Skype call for example, the system becomes unusable, and I have to close one of the programs. Tasks like video editing are also quite slow on the machine. So since I’m going to travel in a few weeks, I decided I needed a new laptop. My requirements were 8GB RAM, SSD and HDD support, a 15″ display, the ability to run Ubuntu 18.04, and possibly a […]

Check for Spectre, Meltdown, and L1 Terminal Fault Vulnerabilities with Spectre-meltdown-checker Script

Yesterday, we wrote a little bit about the new speculative execution vulnerability known as L1 Terminal Fault (L1TF) or Foreshadow, and a reader – MHSadri – pointed to an interesting script that checks for all three speculative execution vulnerabilities, and runs in Linux and BSD (FreeBSD, NetBSD, DragonFlyBSD) across multiple architectures: Intel x32, AMD64, Arm and ARM64. Other architectures will also work, but mitigation reporting may not be correct. So I tried it on my own machine, a computer running Ubuntu 18.04 on an AMD FX8350 processor. Installation is easy:

git clone https://github.com/speed47/spectre-meltdown-checker/
cd spectre-meltdown-checker

1 2	git clone https://github.com/speed47/spectre-meltdown-checker/ cd spectre-meltdown-checker

The developer recommends to check the script manually first, just for security sake. You can have two way to run it: either directly inside your OS, or via docker which may be a better idea since it would not be able to mess with your system especially I had to run it with sudo to avoid permission issues. Here’s […]

AIO-3399J Development Board Review with Ubuntu 16.04

AIO-3399J WiFi, Heatsink, USB Firmware Update

Regular readers will know that Firefly team sent me several of their Rockchip boards for evaluation, and I started with a review of ROC-RK3328-CC development board powered by Rockchip RK3328 processor. This time, I went with the high-end AIO-3399J board comprised of a features-packed baseboard and a Rockchip RK3399 system-on-module. Just like with the previous review, I’ve decided to focus on Linux support, in this case Xunbuntu 16.04, and I’ll do an Android review on the company releases Android 8.1 for Firefly-RK3399 board. First Boot with AIO-3399J Board Before booting the board, I inserted the heatsink, and connected the provided WiFi antennas. I also connected some devices and cables, including a mouse, the male to male USB cable to the top USB 3.0 (OTG) port for firmware update, a HDMI cable to my TV, and Ethernet cable, as well as the serial debug board. The final step was to connect […]

Khadas Edge is Both a Standalone Board and a System-on-Module powered by Rockchip RK3399

One of the two most common type of Arm boards are single board computers with everything from processor to memory/storage to ports is placed on a single PCB, and system-on-modules with processor, memory and storage, and sometimes some extra chips with for network connectivity, audio and power management that are supposed to be inserted into a baseboard exposing connectors and headers. The upcoming Khadas Edge board is a little different since it combines both categories into one board with USB receptacles and HDMI output as well as 314-pin MXM3 edge connector to connect to Khadas Captain baseboard, or any other custom compatible baseboard. Khadas Edge will come in three variants (Basic/Pro/Max) with the following specifications: SoC – Rockchip RK3399 hexa core processor with 2x Arm Cortex-A72 up to 1.8GHz, 4x Cortex-A53 up to 1.5GHz, Arm Mali T864 GPU with support for OpenGL ES1.1/2.0/3.0/3.1, OpenVG1.1, OpenCL, DX11, VPU with4K VP9 and 4K […]

Faytech 15″ to 17″ Capacitive Touch PCs Ship with Ubuntu 16.04

Although many can support Ubuntu or other Linux distributions, most Intel based products ship with some version of Windows by default, and the end users may have to install Linux by themselves. While watching a Computex 2018 video on Armdevices.net, I found out FayTech, a company specializing in the design, development, manufacturing and marketing of touchscreen monitors & PCs, showed a 15″ Touch PC powered by an Intel Celeron J1900 “Bay Trail” processor and running Ubuntu 16.04 LTS. So I had a look on the company website, and the 15″ capacitive touch PC (FT15J1900W4G64GCAP) showcased in the video – embedded at the end of this article – comes with the following key features and specifications: SoC – Intel Celeron J1900 quad core processor @ 2.0 / 2.4 GHz with Intel HD Graphics; 10W TDP System Memory – 4GB DDR3L-1333 via 1x SO-DIMM slot, expandable to 8GB Storage – Industrial 64GB […]

ROC-RK3328-CC Board Review, or the Case for Fast Storage and Adequate Power Supply

Firefly team from T-chip company has send me some of their Rockchip development boards, and we’ve already checked the provided boards and accessories, so today I’ll report my experience with one of the board: ROC-RK3328-CC also known as Renegade. I won’t test it with Android, since I have already reviewed RK3328 Android TV boxes such as Zidoo X7, and I’ve been told the team is hard at work with Android 8.1 SDK, so an Oreo image should be released in a few weeks/months. So I had initially planned to report my experience with one of the Linux images, then show how to install mainline Linux (currently 4.17) to the board, and reports what works. However, I encountered many issues, although likely not directly related to the board or its software support, so instead I’ll write about my experience getting started with the board, and list all the issues I had […]
