Khadas VIM3L SBC up for pre-order for $50 and up, VIM1 & VIM2 Price Reduced

Shenzhen Wesion recently unveiled Khadas VIM3L SBC designed for HTPC / media center use cases. The board is based on Khadas VIM3 PCB but replaces the powerful Amlogic A311D processor by Amlogic S905D3 processor that should be just as good for video playback, but enable much cheaper hardware. Khadas VIM3L Pre-orders The board is not quite available yet, but the company has started to take pre-orders for Khadas VIM3L at discounted prices either as a bare board with Android 9.0 pre-installed ($49.99), or as a CoreELEC HTPC kit with enclosure, heatsink, WiFi antennas, and IR remote control ($69.99). Both feature Amlogic S905D3 quad-core Cortex-A55 processor coupled with 2GB LPDDR4(X) RAM, 16GB eMMC flash, and support 4Kp60 video output and playback with HDR support. Prices will increase with time as follows: September 3-16 (Early Bird) – $49.99 and $69.99 for the board and HTPC kit respectively September 17 – October 7 […]

Real-Time Performance and Health Monitoring Using Netdata

Netdata is a real-time open source monitoring tool, that generates hundreds of metrics of performance and health monitoring parameters. Netdata is capable of visualizing this data with real-time capabilities along with alerts and notifications. This monitoring agent can be installed in all variant of Linux systems, Mac OS, FreeBSD and in Raspberry Pi . Netdata provides options for archiving the metrics to a remote server by using TimeSeries Databases and processing engines, and can be visualized using Grafana or other tools. Architecture Overview Metrics collector Fetches various system & health monitoring parameters (uptime, CPU load, CPU usage, RAM utilization, disk usage etc.) . Fetches application metrics including web servers, databases, containers, etc… Netdata’s Internal plugins collect most of the metrics from standard Linux system parameters such as /proc, /sys and other Linux kernel sources External plugins contains ready to use plugins developed by using other programing language and interfaced to […]

How to Sandbox an arm64 GCC on aarch64 Hardware with armv7 Userspace

CNXSoft: Guest post by Blu about setting up arm64 toolchain on 64-bit Arm hardware running a 32-bit Arm (Armv7) rootfs. Life is short and industry progress is never fast enough in areas we care about. That’s an observation most of us are familiar with. One would think that by now most aarch64 desktops would be running arm64 environments, with multi-arch support when needed. Alas, as of late 2019, chromeOS on aarch64 is still shipping an aarch64 kernel and an armhf userspace. And despite the fine job by the good folks at chromebrew, an aarch64 chromeOS machine in dev mode ‒ an otherwise excellent road-warrior ride, is stuck with 32-bit armhf. Is that a problem, some may ask? Yes, it is ‒ aarch64 is the objectively better arm ISA outside of MCUs, from gen-purpose code to all kinds of ISA extensions, SIMD in particular. That shows in contemporary compiler support and […]

Pi-oT Raspberry Pi Add-on Board Targets Commercial & Industrial IoT Automation (Crowdfunding)

USA Based Startup Builds RPi Add-on Pi-oT, a Cleveland based startup has launched a Kickstarter campaign for a Raspberry Pi add-on for commercial and industrial IoT automation. The unit is a full mountable chassis with fan and DIN-rail that extends the Pi’s GPIO with 26-pin terminal connectors and provides 5x relays, 8x ADCs, and power outputs. We have reported on a variety of uses for the Raspberry Pi SBC, from home automation to development in IoT, to hobby projects, and in education settings. It is not surprising to see an automation module developed for IoT industrial applications around the popular and powerful SBC. The Choices The Kickstarter campaign has passed its low initial target and is set to ship at the end of October. There is an early launch discount on the unit’s price of $40 for commercial and $50 for industrial backers. That early bird type special is 15% […]

Microsoft to Support exFAT File System in Linux, Releases exFAT Specification

Microsoft’s exFAT file system is quite popular for removable mass storage devices such as SD cards and USB flash drives as it’s supported in Windows, and many consumers devices such as cameras can handle Microsoft’s patented file system. The “patent” part causes an issue in Linux, as companies need to license it in order to ship it in their products or operating systems image. I recently re-installed Ubuntu 18.04 on my laptop, and if I reinsert my “test” USB drive: BTRFS, EXT-4, and NTFS partitions all mount automatically, but not the exFAT one. If I click on the partition, I get this message: That’s because Canonical does not provide exFAT by default in Ubuntu due to legal issues. It’s however easy enough for the user to install exFAT utilities

sudo apt install exfat-fuse exfat-utils

1	sudo apt install exfat-fuse exfat-utils

The drive will mount successfully:

 mount | grep -i exfat
/dev/sdc3 on /media/jaufranc/USB3_EXFAT type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096,uhelper=udisks2)

1 2	mount \| grep -i exfat /dev/sdc3 on /media/jaufranc/USB3_EXFAT type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096,uhelper=udisks2)

Note that it’s using FUSE (Filesystem in Userspace), and it’s usually not a problem […]
