I have long wanted to 'touch' internet services by setting up a web server from scratch and launching it online. In this article, I want to share the experience of transforming a home router from a narrow-function device into a practically full-fledged server. It all started when my trusty TP-Link TL-WR1043ND router stopped meeting the needs of my home network; I craved the 5GHz band and faster access […]
At the virtual conference 'Open Source Summit and Embedded Linux' held last week, Linus Torvalds discussed the present and future of the Linux kernel in an opening talk with Dirk Hohndel from VMware. During the discussion, the topic of generational change among developers was addressed. Linus pointed out that despite the project's nearly 30-year history, in general, the community […]
Recently, Europol, NCA, the National Gendarmerie of France, and a joint investigative team formed with the participation of France and the Netherlands conducted a joint operation aimed at compromising the EncroChat servers by 'installing technical devices' on the servers in France(1) to facilitate the 'calculation and identification of criminals through the analysis of millions of messages and hundreds of thousands of images.'(2) Some time after the operation, […]
If your IT infrastructure is growing too quickly, you will sooner or later face the choice of either incrementally increasing human resources to support it or starting automation. For a while, we lived in the former paradigm, and then the long journey towards Infrastructure-as-Code began. Of course, NSPK is not a startup, but such an atmosphere prevailed in the company during its early years, […]
There are two installation options for a containerization system in an already operational machine hall (I will discuss the installation of isolation systems in construction machine halls in the next part). In the first case, we isolate the cold corridor, and in the second – the hot corridor. Each option has its own characteristics, advantages, and disadvantages. Cold Corridor Isolation Principle of Operation: a perforated […] is used to supply cold air flow into the corridor.
Five years after the last release, the SMTP server Sendmail 8.16.1 has been released. The new version includes a significant number of improvements related to STARTTLS support (for instance, the ability to use elliptic curve-based encryption algorithms has been added), logging has been enhanced, new options SSLEngine and SSLEnginePath for using OpenSSL engines have been introduced, and initial support for DANE (DNS-based Authentication of Named […] has been added.
The translation of this article has been prepared ahead of the launch of the "Infrastructure Platform Based on Kubernetes" course. How can you save on cloud costs when working with Kubernetes? There is no one correct solution, but this article outlines several tools that can help you manage resources more efficiently and reduce cloud computing expenses. I wrote this article with Kubernetes for AWS in mind, […]
Recently, I came across a mention of something called NewNode: NewNode is an SDK for mobile development that makes any application immune to any censorship and DDoS, dramatically reducing server load. P2P network. It can theoretically work without the internet. It looked quite chaotic, but interesting, so I started digging deeper. There was no project description in the repository, so […]
The release of the MaXX 2.1 desktop has been presented, with developers trying to recreate the user shell of the IRIX Interactive Desktop (SGI Indigo Magic Desktop) using Linux technologies. The development is conducted under an agreement with SGI, allowing for the complete recreation of all functions of the IRIX Interactive Desktop for the Linux platform on x86_64 and ia64 architectures. The source code is available upon special request and represents […]
Most information security professionals opposed the proposal to abandon the use of the terms 'black hat' and 'white hat'. The proposal was initiated by David Kleidermacher, Vice President of Engineering at Google, who declined to present at the Black Hat USA 2020 conference and suggested the industry move away from the terms 'black hat', 'white hat', and MITM (man-in-the-middle) in favor of […]
A new document has been proposed for inclusion in the Linux kernel, prescribing the use of inclusive terminology. It suggests abandoning the use of the words 'slave' and 'blacklist' for identifiers within the kernel. The word 'slave' is recommended to be replaced with 'secondary', 'subordinate', 'replica', 'responder', 'follower', 'proxy', and 'performer', while 'blacklist' should be replaced with 'blocklist' or 'denylist'. These recommendations apply to new code added to the kernel, but […]
The release includes the following changes: Improved display of metadata; Enhanced FictionBook rendering; Improved interaction with OPDS. Bugs have been fixed, such as: Incorrect extraction of unique identifiers from EPUB; Missing application icon from the taskbar; Unassigned text-to-speech environment variables when using Flatpak; eSpeak NG voice not being selected during text-to-speech configuration testing; Incorrect selection of the __ibooks_internal_theme attribute when using […]
