TL;DR: Haiku is an operating system specifically designed for PCs, and it has several tricks that make its working environment much better than others. But how does it work? Recently, I discovered Haiku, an unexpectedly good system. I am still amazed at how smoothly it operates, especially compared to working environments on Linux. Today, I will delve into […]
The yet-to-be-officially-released Intel Core i9-9900T processor has been tested multiple times in the popular benchmark Geekbench 4, according to Tom's Hardware, allowing us to evaluate the performance of this new model. To start, it's worth noting that Intel processors with a 'T' suffix have reduced power consumption. For example, while the Core i9-9900K has a TDP of 95W, and […]
AMD continues to improve the Btver2/Jaguar compiler code for performance optimization. Surprisingly, Sony has played a huge role in this. The Japanese corporation uses LLVM Clang as the default toolkit for its PlayStation 4. Recall that the console is built on the hybrid 'red' Jaguar chip. Last week, there were updates to the targeted Jaguar/Btver2 code […]
Quietly and inconspicuously, a new version of the popular Haskell language compiler has been released. Among the changes: Support for profiling on 64-bit Windows systems. GHC now requires LLVM version 7. The fail method has been completely removed from the Monad class and is now in the MonadFail class (final part of the MonadFail Proposal). Explicit type application now works for types themselves and not […]
The article begins with a description of possible reasons for the undervaluation of specialists, which can be read by following the 'link'. III Confronting the reasons leading to undervaluation. The virus of the past is incurable – it won't go away until it takes its toll. However, it can and must be resisted – complications should be prevented. Elchin Safarli. (Recipes for Happiness) By identifying the signs and nature of the issues leading to the undervaluation of specialists in workplaces […]
Hello, Habr! My name is Maxim Ponomarenko, and I am a developer at Sportmaster. I have 10 years of experience in the IT field. I started my career in manual testing, then switched to database development. For the past 4 years, accumulating knowledge from both testing and development, I have been involved in test automation at the DBMS level. I have been part of the Sportmaster team for just over a year […]
We continue to discuss tools for evaluating CPU performance on Linux machines. Today, we’ll cover: temci, uarch-bench, likwid, perf-tools, and llvm-mca. More benchmarks: Sysbench, UnixBench, Phoronix Test Suite, Vdbench, IOzone, Interbench, Fio, Hdparm, S, Bonnie, Iometer, DD, vpsbench, HammerDB, and 7-Zip.

Last time, we talked about open-source tools for assessing processor and memory performance. Today, we will discuss benchmarks for file systems and storage systems on Linux — Interbench, Fio, Hdparm, S, and Bonnie. Photo — Daniele Levis Pelusi — Unsplash. Fio (short for Flexible I/O Tester) creates data I/O streams […]
At 1cloud.ru, we have prepared a collection of tools and scripts for assessing the performance of processors, storage systems, and memory on Linux machines: Iometer, DD, vpsbench, HammerDB, and 7-Zip. Explore our other collections with benchmarks: Sysbench, UnixBench, Phoronix Test Suite, Vdbench, IOzone Interbench, Fio, Hdparm, S, and Bonnie.

Bastien Nocera announced a new memory shortage handler for the Gnome desktop. Written in C. Licensed under GPL3. The daemon requires kernel 5.2 or newer. It monitors memory pressure via /proc/pressure/memory, and when a threshold is exceeded, it sends notifications via dbus to processes to curb their appetite. Additionally, the daemon can attempt to maintain system responsiveness by writing to /proc/sysrq-trigger. […]
The modern approach to operation addresses many pressing business issues. Containers and orchestrators make it easy to scale projects of any complexity, streamline the release of new versions, and enhance their reliability, but they also introduce additional challenges for developers. Programmers primarily care about their code: architecture, quality, performance, elegance — rather than how it will be deployed in […]
Red Hat developer Bastien Nocera has announced a potential solution to the memory shortage problem in Linux. This application, called Low-Memory-Monitor, aims to address system responsiveness issues when RAM is limited. It is expected that this program will enhance the experience in the Linux user environment on systems with minimal memory. The operation is straightforward. The Low-Memory-Monitor daemon monitors memory usage and […]
