The Ansible community continually delights with new content – plugins and modules – creating a lot of new work for those involved in Ansible maintenance, as new code needs to be integrated into repositories as quickly as possible. Meeting deadlines isn't always feasible, and the launch of some products ready for release gets postponed until the next official version of Ansible Engine. Until recently, […]
Being a system administrator in a small non-IT company is quite an adventure. The manager sees you as a freeloader, employees during tough times regard you as a deity of networks and hardware, during good times — as a fan of beer and gaming, the accounting department views you as an extension of 1C, and the entire company functions like a driver for successful printer operations. While you dream of a decent Cisco outfit, […]
As you may recall, in early May 2019, the president signed the law on "Sovereign Internet," which will come into effect on November 1. The law is nominally aimed at ensuring the stable operation of the Russian segment of the internet in the event of disconnection from the global network or coordinated attacks. So, what’s next? At the end of May, the Ministry of Digital Development prepared a draft government resolution on "Approval of the Procedure for Centralized Management of Communication Networks […]
In the previous article: Yealink Meeting Server — a comprehensive solution for video conferencing, we described the functionality of the first version of Yealink Meeting Server (YMS), its capabilities, and structure. As a result, we received numerous requests from you to test this product, some of which evolved into complex projects for creating or modernizing video conferencing infrastructure.

To set up authentication with a CAPTCHA, we need nginx itself and its plugins: encrypted-session, form-input, ctpp2, echo, ldap, headers-more, auth_request, set-misc. (I provided links to my forks since I made some changes that haven't yet been merged into the original repositories. A ready-made image can also be used.) First, we set the encrypted_session_key to 'abcdefghijklmnopqrstuvwxyz123456'; Then, just in case, we disable the authorization header […]

Quorum is a blockchain based on Ethereum, developed by JPMorgan, and has recently become the first distributed ledger platform offered by Microsoft Azure. Quorum supports both private and public transactions and has many commercial use cases.

An automated medical center utilizes a variety of devices that must be managed by a medical information system (MIS), as well as devices that do not accept commands but need to relay their operational results to the MIS. However, all devices have different connection options (USB, RS-232, Ethernet, etc.) and ways to interact with them. Supporting all of them within the MIS is practically impossible, […]
Almost always we create our problems with our own hands… our worldview… our inaction… our laziness… our fears. It becomes quite convenient then to float in the public current of sewage templates… since it is warm and fun, while the rest is irrelevant – we can just indulge. But after a major failure comes the realization of a simple truth – instead of generating an endless stream of excuses, pity for […]
Hedy Lamarr was not only the first to appear nude in film and portray an orgasm on camera, but she also invented a frequency-hopping spread spectrum communication system. "I think people's minds are more interesting than their appearance," said Hollywood actress and inventor Hedy Lamarr in 1990, ten years before her death. Hedy Lamarr was a captivating actress of the 1940s […]

But even if this topic isn't central […]
