Serverless computing is one of the most notable trends in cloud computing. The main principle is that infrastructure is the responsibility of the service provider, not DevOps. Resource scaling automatically adjusts to load and has a high speed of variability. Another common feature is the trend towards minimizing and focusing code, which is why serverless computing is sometimes referred to as 'function as a service' […]
This is the first part of a series of instructional articles on creating smart contracts in Python for the Ontology blockchain network using the SmartX smart contract development tool. In this article, we will start exploring the Ontology smart contract API. The Ontology smart contract API is divided into 7 modules: Blockchain & Block API, Runtime API, Storage API, Native API, Upgrade API, Execution Engine API, and […]
We propose to dive back down to a low level and talk about the security of x86-compatible computer platform firmware. This time, the main ingredient of the research is Intel Boot Guard (not to be confused with Intel BIOS Guard!) – a hardware-supported technology for trusted BIOS booting that the computer system vendor can permanently enable or disable during production. Well, the recipe for the study is familiar to us: […]
The non-profit organization lowRISC, with the participation of Google and other sponsors, presented the OpenTitan project on November 5, 2019, which it describes as "the first open-source project to create an open, high-quality hardware root of trust (RoT) architecture." OpenTitan, based on the RISC-V architecture, is a purpose-built chip designed for deployment in data center servers and any other equipment requiring […]
Until recently, IBM Watson Visual Recognition was primarily used for recognizing images as a whole. However, treating an image as a single entity is far from the most effective approach. Now, thanks to a new object recognition feature, IBM Watson users can train models on images with labeled objects for subsequent recognition in any frames. […]
Fault tolerance and high availability are significant topics, so we will dedicate separate articles to RabbitMQ and Kafka. This article is about RabbitMQ, while the next one will cover Kafka in comparison with RabbitMQ. The article is long, so get comfortable. We will examine fault tolerance strategies, consistency, and high availability (HA), as well as the trade-offs that each strategy entails. RabbitMQ can operate […]
WISE-PaaS — (Platform as a Service) is Advantech's cloud platform for the industrial Internet of Things, integrating various tools for data collection, processing, and visualization, automation, and management of devices and artificial intelligence and machine learning systems. The platform combines several ready-made software solution sets for building comprehensive systems in industries such as healthcare, manufacturing, logistics, etc. […]
The transition to Kubernetes and Linux infrastructures during the digital transformation of organizations leads to applications increasingly being built on microservices architecture and, as a result, often becoming complex in terms of routing requests between services. In Red Hat OpenShift Service Mesh, we go beyond traditional routing and offer components for tracing and visualizing such requests, […]
Solid-state drives continue to dominate the market, but despite this, traditional HDDs are still doing well. It is too early to put the 'classic' into the museum, as storing large volumes of data is still most convenient on HDDs. First of all, there is the price question — just compare the cost of SSDs and HDDs with a capacity of one terabyte and above. For the price of a single 2 TB SSD, you could […]
Performance in .NET Core Hello everyone! This article is a compilation of Best Practices that my colleagues and I have been applying for a long time across different projects. Information about the machine on which the calculations were performed: BenchmarkDotNet=v0.11.5, OS=Windows 10.0.18362 Intel Core i5-8250U CPU 1.60GHz (Kaby Lake R), 1 CPU, 8 logical and 4 physical cores .NET Core SDK=3.0.100 […]
One beautiful spring evening, when going home wasn’t appealing, and the unquenchable desire to live and learn burned like a hot iron, the idea arose to tinker with an intriguing feature on the firewall called "IP DOS policy." After some initial exploration and reviewing the manual, I configured it in Pass-and-Log mode to check the output and questionable usefulness of this setting. […]
One and a half years ago, on March 5, 2018, Google released the first alpha version of its Open Source CI/CD project called Skaffold, aimed at creating a "simple and reproducible development experience for Kubernetes," allowing developers to focus on development rather than administration. What makes Skaffold interesting? It turns out it has several advantages up its sleeve, thanks to […]
