If you have a problem with your computer, you may have to go through log files, or as a software engineer, you may be looking for clues about a bug in a debug or error log. It can be done in any text editor, but there may be a better way thanks to lnav Log Files Navigator that allows checking those files more easily and efficiently in a Mac OS or Linux terminal. The following log files are supported by default even if they are compressed with gzip or bzip2: Common Web Access Log format CUPS page_log Syslog Glog VMware ESXi/vCenter Logs dpkg.log uWSGI “Generic” – Any message that starts with a timestamp Strace lnav is open-source software released under a BSD-2 clause in Github. It’s not new at all as some commits were made in January 2010, but it’s new to me, and hopefully to some of you as […]
4K Vision Edge Computing Platform Features Xilinx Zynq UltraScale+ ZU3EG MPSoC
Last year, MyIR Tech introduced MYD-CZU3EG development board powered by a Xilinx Zynq UltraScale+ ZU3EG MPSoC with Arm Cortex-A53 cores and FPGA fabric designed for applications such as cloud computing, machine vision, flight navigation, and other complex embedded applications. The company has now announced another Zynq Ultrascale+ ZU3EG based platform dedicated to machine vision.

MNT Reform Open Source Hardware Laptop Launched for $999 and Up (Crowdfunding)
MNT Reform DIY Arm Linux laptop has been in the works at least since 2017. The open source hardware laptop is also fully modular with Boundary Devices Nitrogen8M SoM featuring NXP i.MX 8M quad-core Cortex-A53 processor and 4GB RAM, M.2 NVMe SSD storage, and standard, replaceable 18650 batteries. The good news is the laptop is now almost ready for prime-time and has been launched on Crowd Supply with price starting at $999 in DIY kit form without storage, and $1,300 for a complete, assembled system with 256GB NVMe storage. If you don’t have that amount of money to spend, but would like to support the project, a $40 MNT Reform T-shirt is also offered. Alternatively, the motherboard only goes for $550. Here’s a reminder of MNT Reform specification: SoM – Boundary Devices Nitrogen8M SoC – NXP i.MX 8MQuad quad-core Cortex-A53 processor @ 1.5 GHz, 1x Arm Cortex-M4F real-time core Vivante […]
TQ Group Announces NXP i.MX 8X ARM Cortex-A35 Modules as the Processor Finally Becomes Available
TQ Group, headquartered in Germany, has launched two NXP i.MX 8X Cortex-A35 modules with TQMa8Xx and TQMa8XxS SoMs, with the latter being SMARC 2.1 compliant, and both targeting various applications ranging from medical devices, HMIs, industrial controllers and industrial Internet of Things (IIoT) to gateways, building automation, transport, and robotics. The press release explains NXP will officially launch i.MX 8X CPUs on May 14, 2020. We first heard about i.MX 8X in 2016, before an official announcement in 2017, and we wrote about Toradex i.MX 8X SoM in 2018, plus 96Boards AI-ML SBC in 2019, so I naively believed the processor had been around for a couple of years, but the Toradex SoM product is still shown as an “early product announcement” [Update: the page has just been updated since it is now shipping as well], and AI-ML board has just launched with 26 units available on Arrow website. Some […]
WiFi & Cellular Router Focuses on Security, Always-on Connectivity with 2GB Free Monthly Data (Crowdfunding – US)
We previously covered Roqos Core RC10 Intel Atom-based AC router that was offered for only $19 with the catch of having to $17 per month for “advanced cybersecurity and parental control features” for at least a year. The company is now back with Roqos Core RC20 AC router that adds supports for cellular connectivity including 2GB per month of cellular data, and a focus on security with built-in VPN service so you can connect securely from anywhere, even public WiFi hotspots. Roqos Core RC20 hardware specification: SoC – Intel Atom E3845 quad-core processor @ up to 1.91 GHz cores System Memory – 2GB RAM Storage – 8GB flash Video Output – HDMI (but not sure whether it’s used since not listed in the specs) Connectivity Wired – 1x Gigabit Ethernet WAN port, 4x Gigabit Ethernet LAN ports Wireless – Simultaneous dual frequency 3×3 802.11ac WiFi 5 and 2×2 802.11n WiFi […]
Congatec conga-TR4 COM Express Module is Powered by AMD Ryzen Embedded SoC
We’ve covered plenty of AMD Ryzen Embedded V1000-series SBCs, and some Ryzen Embedded mini PCs, but so far, we had not written about any AMD Ryzen Embedded V1000 or R1000 system-on-module (SoM) or computer-on-module (CoM), partially because there aren’t many yet, and because we missed Advantech SOM-5871 CPU module earlier this year. But there’s now another option courtesy of Congatec with conga-TR4 AMD Ryzen Embedded COM Express module with consumer or industrial temperature range, and a choice of seven different processors. conga-TR4 COM Express module specifications: SoC (one or the other) AMD Ryzen V1807B quad-core processor @ up to 3.35 GHz with 2MB L2 cache, Vega 11 graphics; 35-54W TDP AMD Ryzen V1756B quad-core processor @ up to 3.25 GHz with 2MB L2 cache, Vega 8 graphics; 35-54W TDP AMD Ryzen V1605B quad-core processor @ 2.0 GHz with 2MB L2 cache, Vega 8 graphics; 12-25W TDP AMD Ryzen V1202B dual-core […]
BashTop is a Linux Resource Monitor for the Terminal
Neil Amstrong of BayLibre recently added ODROID-C4 support to Armbian, fired up Rosetta@Home on the Amlogic S905X3 SBC, and took a screenshot of some kind of advanced htop program showing the Rosetta@Home and other processes running. And… Rosetta@Home starting ! pic.twitter.com/w10hjwppLR — Neil Armstrong @[email protected] (@Superna9999) April 27, 2020 The program used happens to be BashTop a recently released Linux resource monitor written in Bash and running in a terminal. Installing the script and running it is super easy:
1 2 3 |
git clone https://github.com/aristocratos/bashtop cd bashtop ./bashtop |
I tried it in an AMD Ryzen 7 laptop running Ubuntu 18.04. You’ll need at least a 80×25 terminal window, but it looks much better in full screen. It shows CPU use in graphical and text forms, memory and storage usage, a list of processes, as well as network usage both in graphical and text forms. You can also select each individual process to get more information or kill it. […]
