Optimal PostgreSQL performance depends on correctly defined operating system parameters. Poorly configured OS kernel parameters can lead to reduced performance of the database server. Therefore, it is essential that these parameters are tailored to the database server and its workload. In this post, we will discuss some important Linux kernel parameters that can impact performance […]
Mozilla has been nominated for the 'Internet Villain of the Year' award. The initiative was put forward by representatives of the UK Internet Service Providers Association, and the reason was the company's plans to add support for the DNS over HTTPS (DoH) protocol in Firefox. The essence is that this technology will allow bypassing content filtering restrictions imposed in the country. The Internet Services Providers Association (ISPAUK) accused the developers of this. The gist is […]
After two years of development, the stable release of the modular multi-platform boot manager GNU GRUB 2.04 (GRand Unified Bootloader) has been presented. GRUB supports a wide range of platforms, including standard PCs with BIOS, IEEE-1275 platforms (PowerPC/Sparc64-based hardware), EFI systems, RISC-V, MIPS-compatible Loongson 2E processor hardware, Itanium systems, ARM, ARM64, and ARCS (SGI), devices using the free CoreBoot package. The main […]
Most modern programmers have received their education at universities. Over time, this will change, but currently, the reality is that skilled personnel in IT companies still come from universities. In this post, Stanislav Protasov, director of Acronis for university relations, shares his vision of the peculiarities of university training for future programmers. Educators, students, and employers can even […]
In this article, I will discuss how the project I am working on transformed from a large monolith into a set of microservices. The project began its journey quite some time ago, in the early 2000s. The first versions were written in Visual Basic 6. Over time, it became clear that developing in this language would be difficult to maintain in the future since the IDE […]
Users highly dislike it when the online resource they need is slow. Survey data indicates that 57% of users will leave a webpage if it takes longer than three seconds to load, while 47% are only willing to wait two seconds. A one-second delay can result in a 7% loss in conversions and a 16% decrease in user satisfaction. Therefore, it is essential to be prepared for increased load and traffic spikes. […]
As part of the Snuffleupagus project, a module is being developed for connecting to the PHP7 interpreter, aimed at enhancing the security of the environment and blocking common errors that lead to vulnerabilities in running PHP applications. The module also allows for the creation of virtual patches to address specific issues without modifying the source code of the vulnerable application, which is convenient for use in shared hosting systems where achieving...

Linux offers a wide range of tools for debugging the kernel and applications. Most of them negatively impact application performance and cannot be used in production. A couple of years ago, another tool was developed — eBPF. It allows for tracing the kernel and user applications with low overhead and without the need for recompiling programs or loading third-party […]

Let me say right away: the rat in the delivered server, which we once fed tea after it was electrocuted, has probably escaped. Because we once saw its friend during a routine check. We immediately decided to install ultrasonic repellents. Now the cursed land surrounds the data center: birds don't sit on the building, and all the moles and worms have probably fled. We were concerned that the sound […]
