Server Containers: virtualisation without emulation
Server Containers explained
  • Know-how

The introduction of Software containers is widely regarded as a revolution in server administration. The idea of isolating applications in virtual runtime environments is nothing new, but with platforms like Docker, users can enjoy extensive functionality, which facilitates working with server containers. So, what exactly can application containers do?

RFID (radio frequency identification)
Radio Frequency Identification (RFID)
  • Know-how

RFID, technology to identify objects with the help of electromagnetic waves, is revolutionizing logistics processes and merchandise management systems. Concepts for automating production processes in the context of the future project Industry 4.0 also rely on RFID systems. We explain to you how radio frequency identification works and what fields of application there are.

Reverse DNS
Reverse DNS (rDNS)
  • Know-how

Although address management on the internet is highly complex, it is clearly regulated by the Domain Name System. The system ensures that clients and servers can easily communicate with each other. It also allows reverse DNS checks which can find the hostname for any IPv4 or IPv6 address. This article explains how this works, and for what purpose these requests are made.

Reverse ARP
RARP (Reverse Address Resolution Protocol)
  • Know-how

Out-dated technology can still be interesting. Even though the Reverse Address Resolution Protocol was introduced in 1984, and considered obsolete the following year due to the Bootstrap Protocol, it continued to be used long after. The RARP has not completely disappeared from network technology even today. As the Reverse ARP, this protocol is a counterpart to the Address Resolution Protocol. But...

REST: the HTTP solution for web services
REST (Representational State Transfer)
  • Know-how

Combining different application systems has become increasingly important over the past few years. This trend is especially due to the increasing number of web applications being developed. In order to react to this trend, many different web services were developed that make data transfer across multiple systems possible. The Representational State Transfer (REST) is an architectural style that...

Raspberry Pi alternatives: Single board computers to check out
Raspberry Pi alternatives
  • Know-how

Raspberry Pi is the first choice for do-it-yourselfers around the world when it comes to single-board computers: It’s small, cheap, and meets most server and media center requirements. But more and more manufacturers are putting their own mini-computers on the market: Raspberry Pi alternatives want to set themselves apart with lower prices, more powerful hardware, or edgy and exceptional features....

Quad9 DNS
Quad9
  • Know-how

The Domain Name System (DNS) is important for day-to-day web browsing. However, it is increasingly obvious that the conventional DNS has some weaknesses. New providers are attempting to fill in the gaps. One of them is Quad9. Given that it has no commercial interests – and that it provides a high level of security and privacy – the public DNS resolver is a genuine alternative to the more widely...

Qt
The C++ framework Qt
  • Know-how

Frameworks are an integral element of software development. The collections of tools, libraries and ready-to-use components standardize and simplify the development process, which means a great deal of time can be saved when creating new applications. For example, the framework based on C++ Qt supplies diverse tools for the creation of cross-platform user interfaces; it is also convincing due to...

Public Cloud
Public Cloud
  • Know-how

Cloud computing is an important aspect of digitization. An offshoot of this technology is the public cloud, which provides storage space and IT services publicly on the internet. Data protectors see certain dangerous weaknesses in this concept, but public access offers enormous potential, and data protection concerns are increasingly stimulating innovative solutions. We explain what lies behind...
