Green Metrics Tool helps developers measuring & optimizing software power consumption

The Green Metrics Tool (GMT) is an open-source framework that allows the measurement, comparison, and optimization of the energy consumption of software with the goal of empowering both software engineers and users to make educated decisions about libraries, code snippets, and software in order to save energy along with carbon emissions. While the firmware of battery-powered embedded devices and the OS running on your smartphone are typically optimized for low power consumption in order to extend the battery life, the same can not be said of most software running on SBCs, desktop computers, and servers. But there are still benefits of having power-optimized programs on this type of hardware including lower electricity bills, a lower carbon footprint, and potentially quieter devices since the cooling fan may not have to be turned on as often. The Green Metrics Tool aims to help in that regard. The developers explain how that works: […]

FOSDEM 2023 schedule – Open-source Embedded, Mobile, IoT, Arm, RISC-V, etc… projects

After two years of taking place exclusively online, FOSDEM 2023 is back in Brussels, Belgium with thousands expected to attend the 2023 version of the “Free and Open Source Developers’ European Meeting” both onsite and online. FOSDEM 2023 will take place on February 4-5 with 776 speakers, 762 events, and 63 tracks. As usual, I’ve made my own little virtual schedule below mostly with sessions from the Embedded, Mobile and Automotive devroom, but also other devrooms including “Open Media”, “FOSS Educational Programming Languages devroom”, “RISC-V”, and others. FOSDEM Day 1 – Saturday February 4, 2023 10:30 – 10:55 – GStreamer State of the Union 2023 by Olivier Crête GStreamer is a popular multimedia framework making it possible to create a large variety of applications dealing with audio and video. Since the last FOSDEM, it has received a lot of new features: its RTP & WebRTC stack has greatly improved, Rust […]

GL.iNet Beryl AX OpenWrt router review – WiFi 6 performance, repeater, NAS, and 4G hotspot modes

Power bank GL.iNet GL-MT3000 Beryl AX router

In the first part of the review of GL.iNet GL-MT3000 “Beryl AX” pocket-size WiFi 6 OpenWrt router we had a look at the specifications, the package content, and the hardware design with a teardown of the little router. I’ve now had more time to play with the router focusing the review on WiFi 6 performance, and some of its functions such as repeater, NAS, and 4G hotspot. The router also supports VPN client and server modes, the Tor network, and Adguard Home, but I’ll invite readers to check out the GL.iNet Brume 2 security gateway review since I went through all these, and the hardware is very similar minus wireless connectivity. Initial setup of the Beryl AX router If you connect an Ethernet cable to the router you can switch to step two. If you only rely on WiFi for the setup that works too as the Beryl AX router […]

U-boot now supports booting Linux from an HTTP server

Up until now, U-boot would only support the User datagram protocol (UDP) allowing for TFTP and NFS boot, but Linaro has now added support for TCP and HTTP in U-boot in order to boot Linux from common web servers. TFTP boot from U-boot has been supported for years, as around the year 2006 I remember implementing TFTP Linux boot for a Karaoke system in order to lower the BoM cost by selecting a smaller flash device, and I also explained how to boot Linux on a TV box with TFTP back in 2014. This requires installing a TFTP server on your server, which is quite a trivial task, but HTTP servers are omnipresent, so it’s a welcome addition to U-boot. If you want to use HTTP to boot Linux, it needs to be enabled in the U-boot config:

CONFIG_PROT_TCP=y
CONFIG_PROT_TCP_SACK=y
CONFIG_CMD_WGET=y

CONFIG_PROT_TCP=y

CONFIG_PROT_TCP_SACK=y

CONFIG_CMD_WGET=y

The top and bottom options are pretty obvious, and the second […]
