The Ontology Wasm technology reduces the cost of transferring dApp smart contracts with complex business logic to the blockchain, significantly enriching the dApp ecosystem. Currently, Ontology Wasm simultaneously supports development in both Rust and C++. The Rust language better supports Wasm, and the generated bytecode is simpler, potentially further reducing the cost of contract calls. […]
That's right, after the release of Hashicorp Consul 1.5.0 in early May 2019, Consul can natively handle authorization for applications and services running in Kubernetes. In this guide, we will create a Proof of Concept (PoC), showcasing this new feature step by step. Basic knowledge is expected from you […]
Hello, colleagues! Today, I would like to discuss a highly relevant topic for many Check Point administrators: 'Optimization of CPU and RAM.' It is not uncommon for gateways and/or management servers to consume unexpectedly high amounts of these resources, and I would like to understand where they are 'leaking' and to use them more efficiently if possible. 1. Analysis For analyzing CPU load, it's helpful to use the following commands, which […]
Once, I had a ridiculous idea to gather 500 laser pointers in one place. I spent a lot of time and did it. It turned out to be spectacular and useless, but I enjoyed it. Six months ago, I had another ridiculous idea. This time it was not very spectacular but much more useful. I also spent a lot of time on it. And in this article […]
Aleksey Lizunov, head of the remote service competency center of the IT department at MKB. As an alternative to the ELK stack (ElasticSearch, Logstash, Kibana), we are conducting research on using ClickHouse as a data storage solution for logs. In this article, we would like to share our experience with ClickHouse and the preliminary results from the pilot […]
Hello, Habr! I present to you the translation of Stephen Wolfram's post "The Wolfram Function Repository: Launching an Open Platform for Extending the Wolfram Language." The Foundations of the Viability of the Wolfram Language Today we stand on the brink of great achievements with the Wolfram Language programming language. Just three weeks ago, we launched a free Wolfram engine for developers to help our users integrate […]
Zero Trust is a security model developed by former Forrester analyst John Kindervag in 2010. Since then, the Zero Trust model has become the most popular concept in cybersecurity. Recent mass data breaches only confirm the need for companies to pay more attention to cybersecurity, and the Zero Trust model might prove to be the right approach. Zero Trust denotes a complete absence of […]
Hello everyone! We are launching a series of articles dedicated to solving practical tasks related to Natural Language Processing (NLP) and creating dialogue agents (chatbots) using the open-source library DeepPavlov developed by our team at the MIPT Laboratory of Neural Systems and Deep Learning. The main goal of this series is to introduce a wide range of developers to DeepPavlov and demonstrate how […]
An increasing number of users are migrating their entire IT infrastructure to the public cloud. However, if antivirus control is insufficient in the customer's infrastructure, serious cyber risks arise. Practice shows that up to 80% of existing viruses thrive well in virtual environments. In this post, we will discuss how to protect IT resources in the public cloud and why traditional antivirus solutions are not entirely suitable for these […]
Clouds are like a magic box — you specify what you need, and resources simply appear out of nowhere. Virtual machines, databases, networks — all belong solely to you. There are other tenants in the cloud, but in your universe, you are the sole ruler. You are confident that you will always receive the required resources, without having to consider anyone else, and you determine what […]
The scale of Amazon Web Services' network encompasses 69 zones worldwide across 22 regions: the USA, Europe, Asia, Africa, and Australia. Each zone houses up to 8 data centers (DCs). Each DC contains thousands or hundreds of thousands of servers. The network is designed such that all unlikely scenarios of outages are accounted for. For example, all regions […]
For the past eight years, I have worked as a project manager (not coding at work), which has naturally negatively impacted my technical background. I decided to bridge my technology gap and pursue a career as a Data Engineer. The main skill of a Data Engineer is the ability to design, build, and maintain data warehouses. I have created a learning plan, and I think it will be beneficial not only for me. The plan […].
