Hello everyone in this blog, and welcome to the fourth post in the Quarkus series! The previous post discussed how Quarkus integrates MicroProfile and Spring. Recall that Quarkus is positioned as 'super-fast subatomic Java,' or 'Kubernetes-oriented Java stack optimized for GraalVM and OpenJDK HotSpot, built from the best libraries and standards.' Today we will show how to modernize […]
Hello everyone, and welcome to the third post in the Quarkus series! When developing Java microservices, it is often considered that Eclipse MicroProfile and Spring Boot are separate and independent APIs. By default, programmers tend to use the APIs they are already familiar with, as learning new frameworks and runtime components takes a lot of time. Today we […]
At 9:00 AM: You are holding a video conference in the office via your laptop. 9:00 PM: You are watching a live stream on your mobile phone at home. Wait a minute, have you ever wondered what wireless devices are operating on your seamless network? Of course, you've heard people around you mention routers from time to time. What about wireless access points? […]
I would like to present a transcript of Vladimir Sitnikov's early 2016 report 'PostgreSQL and JDBC: extracting every ounce of performance.' Good day! My name is Vladimir Sitnikov. I have been working at NetCracker for 10 years, primarily focusing on performance. Everything related to Java, everything connected to SQL – that’s what I love. And today I will discuss […]
Today, I will share with you a story. A story about the evolution of computing and the emergence of remote workplaces from ancient times to the present day. The Development of IT The main takeaway from the history of IT is… Of course, that IT develops in a spiral. The same solutions and concepts that were discarded decades ago are gaining new meaning […]
The table and index bloat effect is widely known and is not limited to Postgres. There are 'out-of-the-box' methods to combat it, such as VACUUM FULL or CLUSTER, but these lock tables during operation and therefore cannot always be used. This article will cover some theory on how bloat occurs, how it can be addressed, […]
Since the previous post (the switcher in the "proof of concept" stage) received quite a bit of constructive feedback (which is nice), I've continued to spend my free time developing the project. Now I want to take a bit of your time… The second step will be somewhat unconventional: a proposal/discussion about the configuration design. It turns out that normal programmers find configuring all these knobs dreadfully boring. To avoid […]
The discontinuation of support for xneur has caused me some distress over the past six months (with the introduction of OpenSUSE 15.1 on my desktops: when xneur is enabled, windows lose focus and amusingly flicker in time with keyboard input). "Oh, damn, I started typing in the wrong layout again" — this happens excessively in my work. It doesn't add any positivity. To […]
Please don't rush to conclusions based on the title! We have substantial arguments to back it up, and we have packaged them as compactly as possible. We present to you a post on the concept and principles of our new data storage system, which was released in January 2020. In our opinion, the main competitive advantage of the Dorado V6 storage family is precisely […]
Are you planning to implement Atlassian software (Jira, Confluence)? Don't want to make serious design mistakes that you'll have to resolve at the last minute? Then this is the place for you — we consider the implementation of Atlassian Jira + Confluence in a corporation while taking various technical aspects into account. Hello, I am the Product Owner at RSHB and am responsible for the development of the Lifecycle Management System (LMS) built on […]
ExtremeSwitching V300 is a new line of port expanders from Extreme Networks, operating based on the IEEE 802.1BR protocol. We have already explored this technology in our article "Extreme Extended Edge" or switching based on the IEEE 802.1BR standard. The line consists of five fanless eight-port models with a wide range of possible connections, power supply options, and installation in sensitive environments […]
The "Extreme Extended Edge" solution (also known as Virtual Port Extender – VPEX) is a new technology, first supported in the EXOS operating system starting with release 22.5. The solution is based on the IEEE 802.1BR (Bridge Port Extension) standard, and within the EXOS 22.5 release, support for the new ExtremeSwitching V400 hardware line "VPEX Bridge" was added […]
