  • Decoding LoRa: Realizing a Modern LPWAN with SDR — LoRa is an emerging Low Power Wide Area Network (LPWAN), a type of wireless communication technology suitable for connecting low power embedded devices over long ranges. This paper details the modulation and encoding elements that comprise the LoRa PHY, the structure of which is the result of the author’s recent blind analysis of the protocol. It also introduces grlora, an open source software defined implementation of the PHY that will empower wireless developers and security researchers to investigate this nascent protocol.
  • Nest Wifi announced at Made by Google 2019 | Ars Technica — Google says that a two-piece Nest Wifi kit—one Nest Router and one Nest Point—should cover up to 3,800 square feet and 85% of homes. This claim, like most arbitrary claims of Wi-Fi coverage with no real detail, should be taken with several grains of salt.
  • TP-LINK EAP series Business Wi-Fi Solution — The EAP Series Business Wi-Fi Solution incorporates EAP Series hardware, which provides a smooth, reliable wireless internet experience, and a powerful centralized management platform.
  • Bloody Stupid Johnson | Discworld Wiki — Although evidently able in certain fields, Johnson is notorious for his complete inability to produce anything according to specification or common sense, or (sometimes) even the laws of physics.
  • A Quick Look At EXT4 vs. ZFS Performance On Ubuntu 19.10 With An NVMe SSD — For those thinking of playing with Ubuntu 19.10's new experimental ZFS desktop install option in opting for using ZFS On Linux in place of EXT4 as the root file-system, here are some quick benchmarks looking at the out-of-the-box performance of ZFS/ZoL vs. EXT4 on Ubuntu 19.10 using a common NVMe solid-state drive.
  • ubuntu/zsys: zsys daemon and client for zfs systems — It allows running multiple ZFS systems in parallel on the same machine, get automated snapshots, managing complex zfs dataset layouts separating user data from system and persistent data, and more.
  • Ubuntu ZFS support in 19.10: ZFS on root · ~DidRocks — We are shipping ZFS On Linux version 0.8.1, with features like native encryption, trimming support, checkpoints, raw encrypted zfs transmissions, project accounting and quota and a lot of performance enhancements.
  • Ubuntu ZFS support in 19.10: introduction · ~DidRocks — We want to support ZFS on root as an experimental installer option, initially for desktop, but keeping the layout extensible for server later on.
  • A detailed look at Ubuntu’s new experimental ZFS installer | Ars Technica — If you're new to the ZFS hype train, you might wonder why a new filesystem option in an OS installer is a big deal. So here's a quick explanation: ZFS is a copy-on-write filesystem, which can take atomic snapshots of entire filesystems.
