The first press releases about coherent CFP optical pluggable modules began to appear around 5-6 years ago. At that time, their use in optical density systems was novel and essentially a niche solution. Now, six years later, these modules have firmly entered the telecom world and continue to gain popularity. What types are available, and how do they […]
The signal transmitted through the cable television network consists of a broadband, frequency-divided spectrum. The parameters of the signal, including frequencies and channel numbers in Russia, are regulated by GOST 7845-92 and GOST R 52023-2003, but the content of each channel is at the operator's discretion.

Users change, but hosting and cloud service providers do not. This is the main idea of the presentation by Indian entrepreneur and billionaire Bhavin Turakhia, which he delivered at the international cloud services and hosting expo CloudFest. We were also there, engaging in discussions with providers and vendors, and some thoughts from Turakhia's speech resonated with general sentiments. […]

But loyal fans and those trapped in the ecosystem still continued to use this operating system, making various efforts to keep it alive. But time passed, and Windows XP finally reached the end of its road, as the last one still […]
Half of all websites use HTTPS, and their numbers are steadily increasing. The protocol reduces the risk of traffic interception but does not eliminate the possibility of attacks. We will discuss some of these attacks—such as POODLE, BEAST, DROWN and others—and ways to protect against them in our material. / Flickr / Sven Graeme / CC BY-SA POODLE The POODLE attack was first discovered […]
The new Microsoft Edge browser for PC has not even been released in beta status yet (only Canary and Dev versions are available), but the developers have already added the ability to synchronize favorites in the Android build. In version 42.0.2.3420 for the mobile OS, this feature is now enabled for all users, whereas it was previously available only for a select few.

I automated the task of file associations, which is choosing the program that will open a file from Explorer/Finder. And I’m sharing it. First, the problem: files with needed extensions often don't open by default with anything, and if they do, it's usually something like iTunes. On Windows, necessary associations may even be lost during the installation (or uninstallation) of programs: you might uninstall GIMP, and the ICO files end up owned by […]
When people think about privacy on the Internet, the first thing that comes to mind is the 'incognito' mode in Chrome and other browsers. Many believe that this is sufficient to prevent sites from tracking them, but this is not the case. In this mode, the browser does not save browsing history and deletes cookies, but the provider can still monitor user activity. Additionally, this mode does not hide […]
Cloudflare has introduced the open project xdpcap, which develops a network packet analyzer similar to tcpdump, based on the eXpress Data Path (XDP) subsystem. The project code is written in Go and is distributed under the BSD license. The project has also prepared a library for binding eBPF traffic handlers from applications written in Go. The xdpcap utility is compatible with tcpdump/libpcap filtering expressions […]
