Greetings, Habr readers! In this article, I want to share my experience as a programming teacher for C++ at a technical university college. It was a unique experience in my life that taught me a lot. When it comes to interesting facts from my personal past, this episode stands out as one of the first that comes to mind. Let's get started. First, a little about […]
Do you remember the last time you communicated with technical support? And whether it was a pleasant experience? Neither do I. That's why, in the early days of my first job, I often had to remind myself that my work is important and helpful. At that time, I had just joined support. I want to share my journey in choosing this profession and the conclusions I've drawn […]
Translator's note: This practical note from the creator of LayerCI is an excellent illustration of the so-called tips & tricks for Kubernetes (and beyond). The solution proposed here is just one of the few and, perhaps, not the most obvious (for certain cases, the already mentioned 'native' kubectl port-forward for K8s may suffice). However, it at least allows us to look at […]
A record in the SiSoftware performance test database reveals the testing of a server or workstation built on two mysterious six-core Intel processors. These processors are particularly interesting because they feature a rather unusual amount of second-level cache memory — 1.25 MB per core. This is five times more compared to the 256 KB L2 cache […]
Google has resumed the distribution of updates for its browser on the Android platform. Now users can install Chrome 79 without fearing that it will affect the performance of other applications. Recall that the update distribution for the browser started a few days ago, but was halted due to emerging issues. Developers took this step after numerous complaints from users who reported that […]
The release of Linux Mint 19.3 has been announced, the second update in the Linux Mint 19.x branch, based on the Ubuntu 18.04 LTS package and supported until 2023. The distribution is fully compatible with Ubuntu but differs significantly in the approach to user interface organization and the selection of default applications. The developers of Linux Mint offer a desktop environment that adheres to the classical principles of desktop organization, which […]
Every businessman seeks to reduce costs. The same applies to IT infrastructure. When opening a new office, some might start to grow concerned. After all, you need to set up: a local network; internet access. Preferably with redundancy through a second provider; VPN to the central office (or to all branches); HotSpot for clients with SMS authorization; traffic filtering so that […]
For modern humans, hair is nothing more than an element of visual self-identification, part of an image and persona. Nevertheless, these keratin formations have several important biological functions: protection, thermoregulation, sensation, etc. Just how strong is our hair? It turns out, it is several times stronger than the hair of an elephant or a giraffe. Today, we will explore a study on […]
Yes, this is Benson's mansion. The new mansion — she had never been here. With a maternal instinct, Nilda felt that the child was here. Of course, here: where else would you keep a kidnapped child if not in a secure and protected hideout? The building, dimly lit and therefore barely distinguishable among the trees, loomed as an impregnable mass. There was still the need to get there: the mansion's territory was surrounded by […]
The ICANN Corporation has heeded public protests and suspended the sale of the .ORG domain zone, requesting additional information about the deal, including information about the owners of the questionable firm Ethos Capital. Recall that in November 2019, the closed joint-stock company Ethos Capital, specifically created for this purpose, agreed to purchase the nonprofit organization The Internet Society (ISOC), including the operator Public […]

Key innovations in NetworkManager 1.22: The command 'general reload' has been added to the nmcli interface for reloading NetworkManager settings and DNS parameters; The nm-cloud-setup utility has been added for automatic configuration of NetworkManager in cloud […]
Hanno Böck, author of the project fuzzing-project.org, has pointed out vulnerabilities in interactive compilation interfaces that allow the processing of external code in C. By specifying an arbitrary path in the '#include' directive, the compilation error includes the contents of a file that failed to compile. For example, by inserting '#include <\/etc\/shadow>' in one of the online services, it was possible to retrieve the hash of the root user's password from the file […]
