SSH (Secure Shell) is the backbone of remote system administration and secure remote access, serving millions of developers and system administrators daily. However, when SSH connections fail, the cryptographic nature of the protocol can make debugging challenging. The complex interplay between authentication mechanisms, encryption algorithms, and network layers often obscures the root cause of connection issues. This complexity is further compounded by the protocol's security-first design, where error messages are intentionally vague to prevent potential attackers from gathering system information. Whether we're dealing with key authentication failures, network connectivity issues, or configuration mismatches, understanding the underlying SSH architecture becomes critical for effective troubleshooting.

CAPTCHA is not just a single word that can be defined; it's an acronym consisting of nine words (and two prepositions): Completely Automated Public Turing Test To Tell Computers and Humans Apart. This mouthful was shortened to the concise CAPTCHA to avoid creating yet another hard-to-pronounce term. Translated into Russian, this abbreviation sounds like "Полностью автоматизированный публичный тест Тьюринга для различения компьютеров и людей" (Fully Automated Public Turing Test to Differentiate Computers and Humans).

Опросы – это не просто инструмент сбора мнений; они являются мостом между компаниями и их аудиторией, позволяя не только узнать мнение клиентов, но и вовлечь их в процесс создания и улучшения продуктов и услуг.

In any history textbooks, the modern time has already been called the time of the next change of the industrial structure or the fourth industrial revolution (Industry 4.0). The main role, in this case, is given to information and IT systems. In an attempt to reduce the cost of IT infrastructure, unify and accelerate the process of developing IT solutions, humanity first invented "clouds" in order to replace traditional data centers, and then containers to replace virtual machines.

Clearly, containers appear more vulnerable from a security point of view. What are the advantages of containerization over virtualization? In fact, there are quite a lot of them:

• the possibility of more flexible use of available resources (no need to backup them as in the case of virtual machines);

• the ability to save resources (no need to spend them on many copies of the OS for each virtual machine);

• no delays at startup (just start of the process is almost instantaneous compared to the time needed to load the virtual machine);

• the interaction between processes, even if isolated, is much easier to implement when needed than between virtual machines. That is how, by the way, came the concept of microservices, which has recently become very popular.

All of the above led to the very rapid development of container technologies, despite the recurring problems with the security of already deployed container cloud systems, their hacks, and data leaks. Accordingly, the work on strengthening container security is also continuing. This is what will be discussed further in this article.

The potential of VoIP to your customers is simply phenomenal. Businesses are experiencing the advantages of VoIP’s cost-efficiency and reliability and now you can pass these benefits onto your own customers very easily. Cloud telecommunication is sophisticated and easily integrated. Confidence in this technology is growing fast. There has never been a better time to start talking to your customers about adopting this solution. It will deliver huge business benefits for them and has the potential to increase business income and profitability.

Speech analytics is the process of analysing recorded speech, such as phone calls, to gather customer information to improve communication and future customer interaction. Speech analytics as a technology has been evolving especially rapidly over the last few years. It gives the ability to structure and analyse previously lost streams of insight-rich data, such as phone conversations. Empowered with this technology, operations can gather incredibly valuable business intelligence to drive call delivery performance improvements. It’s smart in that it automatically identifies focus areas in which customer service or sales teams may need additional call training which then, in turn, improves the call’s successful outcome. Speech analytics, as a process, can isolate buzzwords and phrases used most frequently within a given time period, plus indicate usage is trending up or down. This data is highly useful to call managers to spot changes in consumer behaviour so that action can be taken to improve customer satisfaction.

Zadarma is a leading global VoIP provider and offers a smart speech analytics feature as part of their incredibly easy to use telecommunications offering. The tool is free as part of the wider PBX phone system bundles, included in the free recognition minutes. Zadarma’s analytics feature allows data access to every internal or external call conversation. The benefits of speech analytics include:

What already happened

• Batch jobs.
• Workloads that can sustain and/or recover from interruptions.
• Development and test.
• Stateless applications that can use Spot Virtual Machines to scale out, opportunistically saving cost.
• Short-lived jobs which can easily be run again if the Virtual Machine is evicted.
