The release of the desktop-oriented operating system MidnightBSD 1.2 has taken place, based on FreeBSD with elements ported from DragonFly BSD, OpenBSD, and NetBSD. The base desktop environment is built on GNUstep, but users have the option to install WindowMaker, GNOME, Xfce, or Lumina. An installation image of 663 MB (x86, amd64) has been prepared for download. Unlike other desktop builds of FreeBSD, the MidnightBSD OS has originally developed […].
A corrective update for Firefox 70.0.1 has been released, addressing an issue that causes crashes when opening certain pages or loading specific elements on pages via JavaScript. This problem also appears on sites like YouTube and Facebook due to corruption of content in the new LocalStorage (NextGen) implementation. Due to issues in Firefox 70.0.1, a rollback has been carried out on […]
The developers of OpenBSD have prepared a portable release of the OpenBGPD 6.6 routing package, which can be used on operating systems other than OpenBSD. To ensure portability, parts of the code from the OpenNTPD, OpenSSH, and LibreSSL projects have been used. Support for Linux and FreeBSD has also been declared. OpenBGPD has been tested on Debian 9, Ubuntu 14.04, and FreeBSD 12. The development of OpenBGPD is supported by the regional […]
Last time we discussed the features of the new NB-IoT standard from the perspective of radio access network architecture. Today, let’s explore what has changed in the core network with NB-IoT. So, let's go. Significant changes have occurred in the core network. First, a new element has been introduced, as well as a series of mechanisms defined by the standard as 'CIoT EPS Optimization' or optimization […]
In the article 'NB-IoT: How It Works? Part 2', while discussing the architecture of the NB-IoT core network, we mentioned the introduction of the new SCEF node. In this third part, we explain what it is and why it is needed. When creating M2M services, application developers face the following questions: how to identify devices; what algorithm to use for authentication and confirmation; which one to choose […]
In August 2019, Russia executed the world's first commercial project for wireless backup of a trunk optical cable with a capacity of 40 Gbps. The operator 'Yedinstvo', a subsidiary of Norilsk Nickel, used such a channel to establish an 11-kilometer wireless backup across the Yenisei River. Periodically, articles about world records in wireless communication appear in the press, including on Habr. […]
Good day, dear Habr readers! Continuing the trend of emigration, I would like to share my personal experience, which may be useful to others. I will try to divide the post into two parts, the first of which will focus on practical information, while the second will delve into my own feelings. Part one. The Process. In my case, the process of registration was quite simple (due to the absence of a wife […]
The developers of Firefox have decided to discontinue support for extensions that are installed through direct file copying to the extensions directory (/usr/lib/mozilla/extensions/, /usr/share/mozilla/extensions/, or ~/.mozilla/extensions/), which is processed by all instances of Firefox in the system (regardless of user). This method is usually applied for pre-installing extensions in distributions, substituting extensions during the installation of some application in the system, or for isolated delivery of an extension […]
The Python language developers have decided to switch to a new release preparation scheme. New major releases of the language will now be released once a year, rather than once every eighteen months as it was previously. Thus, Python 3.9 can be expected in October 2020. The total development time for a major release will be 17 months. Work on the new branch will be […]
Trendy technological services are changing our internet habits. I love files. I enjoy renaming them, moving them, sorting them, changing their display in folders, creating backups, uploading them to the internet, restoring, copying, and even defragmenting them. As a metaphor for how to store a block of information, I think they are magnificent. I like the file as a whole. If I need to write an article, it […]
I am a system administrator at FirstVDS, and this is the text of the first introductory lecture from my short course aimed at helping new colleagues. Specialists who have recently started their journey in system administration face a number of common issues. To offer solutions, I decided to write this series of lectures. Some aspects are specific to hosting technical support, but overall, they might […]
Currently, many projects are being launched aimed at replacing existing information security tools. This is unsurprising, as attacks are becoming increasingly sophisticated, and many security measures can no longer provide an adequate level of protection. Throughout these projects, various challenges arise—finding suitable solutions, trying to stay within budget, procurement, and the actual migration to new solutions. Within […]
