The working group began developing the standard back in 2014 and is currently working on draft 3.0. This differs somewhat from previous generations of the 802.11 standards, as their work was completed in two drafts. This is due to the large number of planned comprehensive changes, which consequently require more detailed and complex compatibility testing. Initially, the group faced […]
The release of the decentralized file system IPFS 0.6 (InterPlanetary File System) has been published, forming a global version-controlled file storage deployed as a P2P network composed of participant systems. IPFS combines ideas previously implemented in systems like Git, BitTorrent, Kademlia, SFS, and the Web, and resembles a single 'swarm' of BitTorrent (peers participating in the distribution) exchanging Git objects. IPFS features content-based addressing, and […]

Hello everyone. I couldn't find a comprehensive guide online for logging and collecting metrics from third-party services in systems deployed on Kubernetes. I'm publishing my solution. This article assumes you already have a working Prometheus and other services. As an example of a data source from an external stateful service, we'll use a PostgreSQL database in a Docker container. The company uses […]
The mechanism for developing a custom application and uploading it to the module is available for both Linux and Windows operating systems. In this article, we will detail how to compile and upload a custom application to the module using examples from the SDK provided by SIMCom Wireless Solutions. Before writing this article, a friend of mine, who is unfamiliar with Linux development, asked for an in-depth […]
What is TANGO? It is a system for managing various hardware and software. TANGO currently supports four platforms: Linux, Windows NT, Solaris, and HP-UX. This will describe working with Linux (Ubuntu 18.04). Why is it needed? It simplifies the interaction with different hardware and software. You don’t have to worry about how to store data in the database; that's already […]
