Many foreign authors agree that the era of Big Data has come to an end. In this context, Big Data refers to technologies based on Hadoop. Many authors can even confidently name the date when Big Data left this world, and that date is June 5, 2019. What happened on that significant day? On that day, […]
In IT, there is a superstition: "If it works, don't touch it." This can also be said about our monitoring system. At Southbridge, we use Zabbix — when we chose it, it was very good. Essentially, there were no alternatives. Over time, our ecosystem developed documentation, additional bindings, and integration with Redmine. Zabbix acquired a powerful competitor, […]
What is mobile Internet, like 4G, for? To travel and stay connected at all times. Away from megacities, where there's no usual free Wi-Fi, life flows at a calm pace. It's also essential for accessing the Internet while visiting remote sites where central access hasn't been established, connected, or paid for […]
The eXpress Data Path (XDP) technology allows for arbitrary traffic processing on Linux interfaces before packets reach the kernel's network stack. Applications of XDP include DDoS attack protection (CloudFlare), complex filtering, and statistics collection (Netflix). XDP programs are executed by the eBPF virtual machine, which imposes limitations on both their code and the available kernel functions depending on […]

Why use Sonatype Nexus? For storing private artifacts; for caching artifacts downloaded from the internet; artifacts supported in the base install of Sonatype […]
One of the main challenges in the development and subsequent operation of microservices is the thoughtful and careful configuration of their instances. In my opinion, the new framework microconfig.io can help with this. It elegantly addresses some of the routine application configuration tasks. If you have many microservices, each with its configuration file(s), there is a high probability […]
So, your team has completed the alpha version of your blockchain, and it’s time to launch the testnet, and then the mainnet. You have a real blockchain with independent participants, a solid economic model, security, you've designed governance, and now it's time to put it all to the test. In an ideal crypto-anarchist world, you deploy the genesis block, the final node code, and the validators themselves […]
Hello, Habr. Raspberry Pi is probably found in almost every home, and I dare say that many might have one lying around unused. However, Raspberry Pi is not just a valuable piece of hardware; it’s also a capable fanless computer running Linux. Today, we will explore useful features of the Raspberry Pi that require no coding at all. For those interested, details […]
Good day! In this article, I will explain how users of regular hosting can capture IP addresses that generate excessive load on their site and then block them using hosting tools. There will be a bit of PHP code and several screenshots. Input data: A site created on the WordPress CMS, Hosting Beget (this is not an advertisement, but the screenshots will be from this hosting provider's admin panel). The WordPress site is running […]
Once, they were at the top of the food chain. For millennia. Then the unimaginable happened: the sky was covered with clouds, and they ceased to exist. On the other side of the world, events changed the climate: cloud cover increased. The dinosaurs became too big and slow; their attempts to survive were doomed to fail. The apex predators ruled the Earth for 100 million years, growing larger and becoming ever […]
