Software configuration tips for Raspberry Pi clusters & parallel-ssh command

I missed that linux.conf.au 2021 took place on January 23-25 2021, and while browsing the schedule I noticed a talk entitled “Building Raspberry Pi Supercomputers” by Federico Lucifredi, Product Management Director for Ceph Storage at Red Hat. In the talk, he mostly focuses on the software part, and besides some basic steps, I learned about some new commands that be useful to people managing clusters of Raspberry Pi or other Linux boards or hosts. Configuring a cluster He used Picocluster image in his example, but for people wanting to use 64-bit OS, he recommends Ubuntu or Fedora images until Raspberry Pi OS 64-bit becomes stable. The first part of the configuration is making sure all the main user is the same on all board, disable SSH for root, and configure run levels (X not needed on clusters). Networking is configured with fixed IP addresses for Ethernet, and DHCP for WiFi. […]

Snapdragon X65 is the world’s first 10 Gigabit 5G modem

Announced in 2017, the first Qualcomm 5G modem – named Snapdragon X50 – could achieve up to 5 Gbps downloads, it was following by Snapdragon X55 with peak download speeds of 7 Gbps, and Snapdragon X60 upped that to 7.5 Gbps in 2020. The company has now unveiled its fourth-generation 5G modem with Snapdragon X65 promising up to 10 Gigabit per second peak download speed. The new modem is also said to be the first to feature a 3GPP Release 16 modem-to-antenna solution and may be used in mobile broadband, fixed wireless, industrial IoT, and 5G private network applications. Qualcomm Snapdragon X65 key features and specifications: 10 Gbps peak speeds in 5G standalone and non-standalone modes 3GPP Release 16 support Cellular Technology – 5G NR, LTE, WCDMA (DB-DC-HSDPA), TD-SCDMA, CDMA 1x, GSM/EDGE 5G Spectrum – mmWave-sub6 aggregation, sub-6 carrier aggregation (FDD-TDD, FDD-FDD, TDD-TDD), Dynamic Spectrum Sharing (DSS) 5G Modes – […]

iPod Classic given new life with Raspberry Pi Zero W & Spotify

Guy Dupont got a bunch of 2004, fourth-generation iPod Classic MP3 players from his mother-in-law, and instead of playing MP3 files on the media players, he decided to repurpose one with a Raspberry Pi Zero W to be able to stream music from Spotify over WiFi. The resulting project is called sPot (ess-pot), and looks just like an original iPod, but it’s a Linux device that can stream/search via Spotify with a UI written in Python and based on the original iPod experience. But apart from the enclosure, and the original “click wheel” there’s not much left from the original design. Besides the Raspberry Pi Zero W SBC and iPod enclosure, the sPod includesAdafruit Mini LiPoly/LiIon USB Charger and PowerBoost 1000 Basic boards for charging and power management, a 1,000mah,3.7V rechargeable li-ion battery, vibration motor discs For haptic feedback, a 2-inch Adafruit TFT display, and a few other components, wires, […]
