So, the official launch of the Red Hat OpenShift 4 platform has taken place. Today, we will show you how to transition to it from OpenShift Container Platform 3 in the quickest and easiest way. In this article, we are primarily interested in the new OpenShift 4 clusters that utilize an immutable infrastructure based on RHEL CoreOS and […]
One of the upcoming updates to the Chrome browser will completely drop support for the FTP protocol. This is stated in a special document from Google addressing this issue. However, the 'changes' will take effect only a year or even longer from now. Proper support for the FTP protocol in the Chrome browser has always been a sore point for developers at Google. One of the reasons for dropping FTP is cited as […]
The release of Apache HTTP Server 2.4.41 has been published (the release 2.4.40 was skipped), which introduces 23 changes and fixes 6 vulnerabilities: CVE-2019-10081 — an issue in mod_http2 that could lead to memory corruption when sending push requests at a very early stage. When using the 'H2PushResource' setting, it may be possible to overwrite memory in the request handling pool, but the problem is limited to a crash, as the data being written […]
When I still lived in an apartment building, I faced the issue of slow speeds in rooms far from the router. Many people have their router in the hallway, where the provider has run fiber or UTP, and where a standard device is also placed. It’s fortunate when the owner replaces the router with their own, but standard devices from providers are like […]
Recently, there has been a plethora of materials online discussing traffic analysis at the network perimeter. However, everyone seems to have forgotten about the analysis of local traffic, which is equally important. This article specifically addresses that topic. Using Flowmon Networks as an example, we will revisit the good old Netflow (and its alternatives) and consider some interesting cases, […]
TL;DR: A description of the client-server architecture of our internal network configuration management system, QControl. It is based on a two-tier transport protocol, working with gzip-packed messages without decompression between endpoints. Distributed routers and endpoints receive configuration updates, and the protocol allows the installation of localized intermediate relays. The system is built on the principle of differential backup (‘recent-stable’, explained below) and utilizes a query language […]
Six-core Ryzen 5 processors gained wide recognition long before AMD transitioned to the Zen 2 microarchitecture. Both the first and second generations of six-core Ryzen 5 became a popular choice in their price segment due to AMD's strategy of offering customers more advanced multithreading than Intel processors can provide, at the same or even […]
Developers at the Czech company Avast Software have announced the release of an updated web browser, Secure Browser, built on the open-source Chromium project with a focus on ensuring user security while browsing the internet. The new version of Avast Secure Browser, codenamed Zermatt, includes tools for optimizing memory and CPU usage, as well as a feature to ‘Extend operation time […]
The release of QEMU 4.1 has been announced. As an emulator, QEMU allows running programs compiled for one hardware platform on a system with an entirely different architecture, for example, executing an ARM application on an x86-compatible PC. In virtualization mode, QEMU’s code execution performance in an isolated environment is close to native systems due to direct execution of instructions on the CPU and the utilization of […]
Oracle has released the industrial distribution of Oracle Linux 7.7, based on the package base of Red Hat Enterprise Linux 7.7. An installation ISO image, sized 4.7 GB and prepared for x86_64 and ARM64 (aarch64) architectures, is available for unlimited download after free registration. Additionally, Oracle Linux offers unlimited free access to the yum repository with binary package updates […]
Google has announced its plan to end support for the FTP protocol in Chromium and Chrome. In Chrome 80, scheduled for early 2020, the gradual disabling of FTP support for users on the stable branch is expected (a flag, DisableFTP, will be added for corporate implementations to restore FTP). In Chrome 82, the code and resources used to facilitate the FTP client will be completely removed. The gradual reduction […]
Among the innovations: It is now allowed to reference enum variants through type aliases, for example, via Self. cargo vendor is now included in the standard distribution. With cargo vendor, you can explicitly download and use a full copy of all source codes of all dependencies. This is useful for companies with monorepositories that want to store and analyze all the source code used in […]
