Where do shooting stars come from?

They have nothing to do with stars. A shooting star is another name for a meteor - a light phenomenon that is observed when a cosmic body enters the Earth's atmosphere. These are cosmic dust, fragments of comets and other small particles that burn up in the earth's atmosphere. Occasionally, large fragments do not have time to burn out and reach the Earth - these are meteorites.

Remember the popular sign: when you see a shooting star, make a wish!

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

New Generation of 14nm Intel Processors 02.04.2016

Intel has announced a new family of Xeon E5-2600 v4 processors (E5-26xx v4, specially designed for flexible cloud infrastructures. The top chip contains 22 cores. The line includes 27 models in total. All of them are based on the 14-nm process technology.

"The new processors have the potential to help businesses, cloud service providers and telcos achieve higher performance, benefit from every new server, and accelerate their transition to software-defined infrastructure."

The Intel Xeon E5-2600 v4 processors are designed for dual-socket servers, dual-socket workstations, and communications equipment. Depending on the model, the processor contains from four to 22 cores. There are 27 models in total (PDF).

Almost all new models support Intel Turbo Boost 2.0 and Intel HT technologies. The electrical power of the chips varies from 50 to 160 watts. LLC cache size varies from 10 to 55 MB, one server can contain up to 24 DIMMs (DDR4 2400 MHz). All chips are made using 14nm technology. Their cost ranges from $213 to $4115 per piece in a batch of a thousand units.

The new processors are equipped with Intel Resource Director Technology (Intel RDT), which enables deeper analysis and control over shared platform resources for more granular control. This improves infrastructure efficiency and reduces total cost of ownership (Total Cost of Ownership - TCO). In addition, there are new options for monitoring processor cache memory, RAM bandwidth, and new cache allocation options.

The technology is able to "see" what kind of load individual threads, applications or virtual machines have on the system, and, for example, allocate processor cache memory, giving priority to more important virtual machines, containers and applications.

The new Xeons have improved data protection. For example, the addition of support for the ADCX/ADOX and PCLMULQDQ command sets made it possible to reduce the time of initiating secure sessions based on the RSA, ECC, and Secure Hash Algorithm (SHA) encryption algorithms by up to 70%.

The Xeon E5-2600 v4 processors have a built-in random number generator for generating encryption keys and a built-in random binary sequence generator for use by third-party software solutions.
