OnionShare runs a web server on the local system that operates as a hidden service […]
The Khronos consortium, responsible for developing graphics standards, has granted developers of open graphics drivers the ability to certify their implementations for compliance with the OpenGL, OpenGL ES, OpenCL, and Vulkan standards, without the need to pay royalties or join the consortium as members. Applications are accepted for both hardware open drivers and fully software-based implementations developed under the auspices of […]
The architecture development for Zen 3 is already complete, as indicated by AMD representatives at industry events. By the third quarter of next year, the company plans to closely collaborate with TSMC to initiate the production of EPYC server processors of the Milan generation, which will be manufactured using second-generation EUV lithography based on 7nm technology. It is already known that the third-level cache for processors with […]
Information about what KDB+ is, the Q programming language, and their strengths and weaknesses can be found in my previous article and briefly in the introduction. In this article, we will implement a service in Q that will process incoming data streams and compute various aggregate functions in a 'real-time' mode (i.e., it will be able to handle all […]
Note from the translator: Lead engineer at Zalando, Henning Jacobs, has repeatedly noticed that Kubernetes users struggle to understand the purpose of liveness and readiness probes, as well as their proper application. Hence, he gathered his thoughts in this concise note, which will eventually become part of the K8s documentation. Health checks, known in Kubernetes as liveness probes (i.e., literally, […]
This is a fairly common myth in the server hardware industry. In practice, hyper-converged solutions (where everything is in one) are needed for many purposes. Historically, the first architectures were developed by Amazon and Google for their services. The idea at that time was to create a computing farm consisting of identical nodes, each with its own disks. All of this […]
Dhall is a programmable configuration language that can be described as JSON + functions + types + import. Changes: Expression syntax has been simplified, where ⫽ is used. Expression syntax with nesting has been simplified. Support for leading separators has been added. Standardization of support for denoting record completeness has been implemented. Caching support in Windows has been improved. Types have been added to package.dhall files. New utilities include: List.{default, empty}, Map.empty, Optional.default. JSON.key {Text, […]
In the Perl 6 repository, a change officially renaming the project to Raku has been adopted. It is noted that although the project has formally received a new name, the renaming of a project that has been in development for 19 years requires significant work, and it will take some time to fully complete the renaming process. For example, replacing Perl with Raku will also require changing mentions of 'perl' […]
Oracle has released a corrective update for the VirtualBox 6.0.14 virtualization system, which includes 13 fixes. Major changes in release 6.0.14 include: compatibility with Linux kernel 5.3 has been ensured; improved compatibility with guest systems that use the ALSA sound subsystem in AC’97 emulation mode; issues with flickering, redrawing, and crashing in some VBoxSVGA and VMSVGA virtual graphic adapters have been resolved […]
Mozilla's developers announced a decision to remove all extensions for integration with search engines that use OpenSearch technology from the Firefox add-ons catalog. It is also reported that support for OpenSearch XML markup in Firefox will be removed in the future, which allowed websites to define scripts for integrating search engines into the browser's search panel. OpenSearch-based add-ons will be removed on December 5.
Last week we released 3CX v16 Update 3 and a new application (mobile softphone) 3CX for Android. The softphone is intended to work only with 3CX v16 Update 3 and above. Many users have had additional questions about the application's operation. In this article, we will answer them and provide more details about the new features of the application. It works […]
The method of learning various disciplines 'by cards,' also known as the Leitner system, has been known for about 40 years. Although cards are most often used to expand vocabulary, memorize formulas, definitions, or dates, the method itself is not just another way of 'rote learning,' but a tool to support the educational process. It helps save time needed to remember a large […]
