An assessment has been conducted on the support level for hardware with the Linux kernel 5.9. The average support for PCI devices across all categories (Ethernet, WiFi, graphics cards, sound, etc.) was 99.3%. A repository called DevicePopulation was specifically created for the study, which presents the population of PCI devices on users' computers. The support status of devices in the latest Linux kernel can be obtained through the LKDDb project. To evaluate hardware support […]
We regularly conduct market research, creating tables with pricing and numerous parameters for dozens of data centers. It occurred to us that we shouldn't let valuable data go to waste. Some may find the data itself useful, while others can use the structure as a basis. The tables contain data since 2016. However, there were too few tables, so we also created graphs and a tariff calculator for server placement, plus added open […]

It should be noted that there is a certain issue related to the inability to integrate software obtained from the Microsoft Store into a user image of Windows 10. Without going into details, I will clarify that […]
After two months of development, Linus Torvalds presented the release of Linux kernel 5.9. Among the most notable changes are: restrictions on symbol imports from proprietary modules into GPL modules, acceleration of context-switching operations using the FSGSBASE processor instruction, support for kernel image compression using Zstd, a reworking of thread priority scheduling in the kernel, and support for the PRP (Parallel Redundancy Protocol) protocol.
Googler is a powerful tool for searching Google (Web, News, Videos, and Site search) from the command line. It displays the title, snippet, and URL for each result, which can be opened directly in the browser from the terminal. Demo video. Initially, googler was created to service servers without a graphical interface, but it quickly evolved into a very convenient tool.
Let me tell you a technical story. Many years ago, I developed an application that included built-in collaboration features. It was a convenient experimental stack that utilized the full potential of early React and CouchDB. It synchronized data in real-time using JSON OT. It was used internally at the company, but its widespread applicability and potential in other fields […]
Wait! Wait! This isn’t just another article about SQL Server backup types. I won't even discuss the differences in recovery models or how to deal with an oversized log. Perhaps (just perhaps), after reading this post, you will manage to ensure that the backup taken by your standard tools runs 1.5 times faster tomorrow night. And […]
Any phone or tablet running on Android is a device controlled by the Linux OS. Yes, it’s a heavily modified OS, but the core of Android is still the Linux kernel. Unfortunately, for most phones, the option to 'wipe Android and install a distribution of your choice' is not available. Therefore, if you want Linux on your phone, you'll have to buy specialized gadgets like the PinePhone, or […]
