Five years ago, I started developing Gophish, which gave me the opportunity to learn Golang. I realized that Go is a powerful language, enhanced by many libraries. Go is versatile: in particular, it easily allows for the development of server-side applications. This article is dedicated to writing a server in Go. We'll start with simple things, like 'Hello world!', and finish with an application that […]
If you are using the mobile version of Skype for everyday communication with colleagues, friends, and family, you may encounter an issue where the messenger automatically answers incoming calls. Currently, an increasing number of users are reaching out to Microsoft support regarding this problem, which has arisen on Android devices.

April 1st is not the best day to announce a new product, as many might think it's just another joke, but the Cloudflare team thinks differently. After all, this is a significant date for them since the address of their main mass product—a fast and anonymous DNS server—is 1.1.1.1 (4/1), which was also launched on April 1st last year. […]
What could prompt such a large company as Lamoda, with its established processes and dozens of interconnected services, to significantly change its approach? The motivation can vary greatly, from legislative requirements to the inherent desire of all programmers to experiment. However, this does not mean that one cannot expect additional benefits. Sergey Zaika (fewald) will explain what specific advantages can be gained by implementing an events-driven API on Kafka, including the bumps along the way and interesting discoveries. […]
Yesterday, completely seriously and with no jokes, Cloudflare announced its new product — a VPN service based on the DNS application 1.1.1.1 for mobile devices utilizing its own Warp encryption technology. The main feature of Cloudflare's new product is simplicity — the target audience for the new service includes typical 'moms' and 'friends' who are unable to purchase and set up a classic VPN on their own […]
Cloudflare has introduced public DNS at the following addresses: 1.1.1.1 1.0.0.1 2606:4700:4700::1111 2606:4700:4700::1001 It is claimed that a 'Privacy first' policy is in place, so users can be assured about the contents of their requests. The service is interesting in that, in addition to standard DNS, it offers the ability to use DNS-over-TLS and DNS-over-HTTPS technologies, which greatly hinders providers from eavesdropping on your requests along the way […]
Philosophical Introduction It is known that there are only two methods for solving problems: The method of analysis or the method of deduction, or from the general to the specific. The method of synthesis or the method of induction, or from the specific to the general. To solve the problem of ‘improving database performance’, this may look as follows. Analysis involves breaking the problem into separate parts and attempting to solve them. […]
Scythe has unveiled an updated version of its relatively small tower-type cooling system, named Byakko 2. It differs from its predecessor primarily with a new fan and a larger radiator. The Byakko 2 cooling system is built on three nickel-plated copper heat pipes with a diameter of 6 mm, which are gathered in a nickel-plated copper base. The pipes […]
The entire history of mankind is a continuous process of breaking chains and creating new, even stronger ones. (Anonymous) Analyzing numerous blockchain projects (Bitshares, Hyperledger, Exonum, Ethereum, Bitcoin, etc.), I realize that from a technical standpoint, they are all built on the same principles. Blockchains are like houses, which, despite their diverse constructions, decorations, and purposes, share a foundation. […]

I learned about you through a mutual friend in San Francisco as someone with some impressive remixes on Soundcloud. The mixes I […]

Welcome to lesson 5! Last time, we completed the installation and initialization of the management server and the gateway. So today, we're going to 'dig around' in their internals, specifically in the settings of the Gaia operating system. The Gaia settings can be divided into two main categories: System settings (IP addresses, Routing, NTP, DNS, DHCP, SNMP, backups, system updates, etc.). These parameters […]
