Thanks to its diverse habitats, both natural and slightly modified by human intervention, Retezat National Park is home to 55 mammal species, more than 23% of Europe's terrestrial mammals. The park provides conditions for the survival of the most important large European carnivores: the lynx (Lynx lynx), the bear (Ursus arctos) and the wolf (Canis lupus)"

A beautiful wild cat was photographed in the #RetezatNationalPark during a wildlife monitoring action carried out by the Retezat National Park employees. The wild cat is a solitary animal that is rarely seen by humans in its natural environment. It is protected by international conventions and there are about 10,000 of them in Romania. It hunts at night and feeds on small mammals and birds.

"Replacing a sort algorithm in the FreeBSD kernel has improved its boot speed by a factor of 100 or more… and although it's aimed at a micro-VM, the gains should benefit everyone." bubblesort on its SYSINITs. We're now running a mergesort which is ~100x faster"

Computer Science (CS) matters - algorithms design in action. FreeBSD 14 (x86-64 and arm soon) has moved from bubblesort to mergesort algorithm in the SYSINIT booting part, making the OS to start aprox 100 times faster!

★ FreeBSD booting in 25 ms
☆ Linux systems at 75-80 ms for the same environment

FreeBSD can now boot in 25 milliseconds

Key factors:

► Satellite and in situ observations independently show an approximate doubling of Earth's Energy Imbalance (EEI) from mid-2005 to mid-2019

► Human-caused factors, internal variability, and climate feedbacks all contribute to the positive trend in EEI

► Marked decreases in clouds and sea-ice and increases in trace gases and water vapor combine to increase the rate of planetary heat uptake

"Earth's climate is determined by a delicate balance between how much of the Sun's radiative energy is absorbed in the atmosphere and at the surface and how much thermal infrared radiation Earth emits to space. A positive energy imbalance means the Earth system is gaining energy, causing the planet to heat up." https://www.nasa.gov/feature/langley/joint-nasa-noaa-study-finds-earths-energy-imbalance-has-doubled/

Joint NASA, NOAA Study Finds Earth's Energy Imbalance Has Doubled

Researchers have found that Earth’s energy imbalance approximately doubled during the 14-year period from 2005 to 2019.

You need 4 main things to build better software:

☑ Precise designs (the specs) for your application, using formal methods

☑ The right programming language to implement the design plans

☑ Proper testing (Validate and Verify)

☑ Prediction to quantify the performance of your application

That's it.
