Two years ago, I already made a post about a simple failover for the okerr website. Now there has been some development of the project, and I also published the source code of the okerr server part under an open license, so I decided to write this small overview on Habr. [ full size ] Who might be interested This may be of interest to you if you […]
In this article, I want to show how easy and free it is to create a failover scheme for a website (or any other internet service) using a combination of Okerr monitoring and a dynamic DNS service. That is, in case of any issues with the main site (ranging from a "PHP Error" on the page to lack of space or a suspiciously low number of orders […]
Netflix is the market leader in internet television, a company that has created and actively developed this segment. Netflix is known not only for its extensive catalog of films and series available from almost any corner of the planet and on any device with a display, but also for its reliable infrastructure and unique engineering culture. A clear example of Netflix's approach to developing and supporting complex systems was presented at DevOops 2019 […]
NGINX has announced the beginning of testing the implementation of QUIC and HTTP/3 protocols in the nginx HTTP server and proxy. The implementation is based on the 27th draft of the IETF-QUIC specification and is available through a separate repository, branched from the 1.19.0 release. The code is distributed under the BSD license and does not overlap with the previously proposed HTTP/3 implementation for nginx from Cloudflare, which is a separate project. Support […]

The second beta release of the Haiku R1 operating system has been published. The project was originally created in response to the closure of BeOS and was developed under the name OpenBeOS, but was renamed in 2004 due to trademark concerns with the name BeOS. Several bootable Live images (x86, x86-64) have been prepared to evaluate the performance of the new release.
In May this year (exact date not reported), a new version 2020.1 of the U++ Framework (also known as Ultimate++ Framework) was released. U++ is a cross-platform framework for creating GUI applications. Innovations in the current version include that the Linux backend now uses gtk3 by default instead of gtk2. The look and feel on Linux and MacOS has been redesigned and better supports dark themes. ConditionVariable and Semaphore have received new features.
The Capacity Tier (or as we refer to it internally at Veeam — cap tier) first appeared in Veeam Backup and Replication 9.5 Update 4 under the name Archive Tier. Its underlying idea is to allow backups that have fallen outside the so-called operational restore window to be moved to object storage. This helped free up disk space for those backups.
How to Ensure Time Itself Doesn't Lie When You Have Millions of Large and Small Devices Interacting via TCP/IP? Each of them has a clock, and the time must be correct on all of them. This problem cannot be solved without NTP. Let's imagine for a moment that difficulties arose in one segment of industrial IT infrastructure.
A vulnerability in the USB stack (CVE-2020-7456) has been addressed in FreeBSD, which allows code execution at the kernel level or in user space when a malicious USB device is connected to the system. USB HID (Human Interface Device) descriptors can place and extract the current state, allowing the consolidation of element descriptions into multilevel groups. FreeBSD supports up to 4 such levels of extraction. If a level is not specified, it defaults to the highest one.
