Ubuntu 22.04 performance getting closer to Windows 11

Ubuntu Linux Windows 11 desempenho Kernel

Comparing Windows 11 to Ubuntu and other Linux distributions was par for the course. Microsoft’s system manages to have mixed performance compared to these distributions, which shows it still has a lot of room to go.

The new comparison showed the good performance of Ubuntu 22.04, which gained momentum with Linux 5.19. It is much closer to Windows 11 and therefore closer to mastering this area of ​​interest to many users.


Ubuntu approaches Windows 11

Phoronix compares the performance of Linux and Windows 11 systems. They use a series of well-standardized benchmarks to evaluate what each system has to offer. The latter pitted Ubuntu 22.04 LTS against Windows 11.

To be fair, the same hardware was used, a Lenovo ThinkPad X13 Gen 3, with a well-known default configuration:

  • Ryzen 7 PRO 6850U with Radeon 680M
  • 16 GB LPDDR5-6400
  • 512 GB Micron NVMe SSD
  • Ubuntu 22.04 LTS com Linux 5.15 kernel
  • Ubuntu 22.04 LTS with Linux 5.19
  • Windows 11 Pro

This new test now uses Linux 5.19 and follows another recently done. This one used Linux 5.18 on an Intel Alder Lake system and showed that Linux was closing up the space it had for Windows.

Linux 5.19 kernel improves performance

First, there have been browser performance tests, and in the case of Google Chrome, the results are mixed. While benchmarks such as WebXPRT show gains of around 50%, others such as Basemark show little improvement, well ahead of Windows 11.

However, as with Firefox, Linux 5.19 showed generally more favorable performance, even outperforming the Windows 11 system. While browser benchmarks showed the biggest improvement in the new 5.19 kernel, the rest of the benchmarks are a bit confusing.

For example, in the LuxCoreRender Physically Based Rendering (PBR) test, Linux 5.19 on Ubuntu 22.04 LTS shows no improvement. In fact, the performance actually drops a bit, and depending on the scene used, Ubuntu and Windows 11 exchange shocks from some angles.

Interestingly, in the JPEG image encoding test, the Ubuntu test system seems to outperform the Windows 11 system when the encoding speed is lower. However, Windows 11 speeds up as the encoding speed increases.

Meanwhile, in a compression test using the Zstandard data compression algorithm, Windows 11 is well ahead of Linux. In gaming tests, Windows performance on OpenGL is terrible on AMD. This may change with the release of the new WDDM 3.1 Radeon driver, which shows an increase of up to 55%.

In the Yamagi Quake II benchmark below, the OpenGL API performs very well on Windows 11. However, Vulkan's performance doesn't even come close. You can find all the results of these tests in more detail no site yes Phoronix.

Mathematical trick discovered that could revolutionize landings on the Moon and Mars

Published

Imagem da Lua com detalhe

Space travel is a complex, confusing and dangerous topic. There are many variables that can turn a mission into a disaster. From launch to landing, everything must be very well planned, studied and simulated. Photographs taken by probes and robots can help, but they are far from the necessary information. However, all this may change with the advent of a new method of photomapping. A math trick will help you land safely on the Moon, Mars, and any other planet.

Landform mapping on our natural satellite is of great interest and importance for future human missions.

Photo mapping creates high-resolution surface maps

Researchers have discovered a method for creating high-resolution maps of the surfaces of planets such as the Moon by combining available images and topographic data.

Mapping the complex and varied surface of a world like the Moon at detailed resolution is challenging because laser altimeters, which measure changes in altitude, operate at a much lower resolution than cameras. And although photographs give a sense of surface features, it is difficult to translate images into a specific height and depth.

However, the new method combines topographic data with the degree of sunlight shading in optical images to provide a much more accurate assessment of fill shapes and structures. In the future, the development could help both astronauts and research robots.

The new method was developed by Iris Fernandes, a former PhD student at the Niels Bohr Institute at the University of Copenhagen, Denmark.

Imaging researcher Iris Fernandez, who discovered a new method for mapping lunar soil images.

Lots of missions, lots of photos, but... lacks mathematical rigor

Different missions provide data at very different resolutions, so combining different data sources with different resolutions is a huge mathematical problem. Iris Fernandez and her then supervisor, geophysicist Klaus Mosegaard, did differently, as they focused on the mathematics of the problem, reducing the problem of determining whether an equation could solve the problem.

So it was. It can be said that my supervisor, Professor Klaus Mosegaard, and I have found the mathematical key to a door that has remained closed for many years.

Iris Fernandez mentioned in a statement about his discovery, published on the website university.

It should also be noted that the new approach also requires much less computing power and is much faster than previous methods, according to the researchers.

The moon was the first target of exploration

Researchers have demonstrated the technique on the moon. These combined high-resolution images from NASA's LROC camera Lunar Reconnaissance Orbiter with lower resolution spacecraft data Lunar orbiter laser altimeter (LOLA), the authors of the article claim to have increased the resolution of the topography from about 60 meters per pixel to 0.9 meters per pixel.

In this follow-up, the authors of the study noted that this method can be applied to extract accurate topographic information about rocks on planetary bodies such as the Moon, Mars, asteroids, and any other worlds for which topographic data is available.

This method can be used to solve a number of different problems, including determining the safety of astronauts and rovers or detecting geological points of interest, and can be applied to images from satellites, rovers, or other spacecraft.

The progress of the investigation is described in an article published on June 8 in the journal Planetary and space science.

Year 10 students of the Escola Secundária do Marco Professional Course in Fashion Design participated in the design of the costumes for the Artâmega – Marco de Canaveses Arts Conservatory show “Perhaps in the Heart”, filmed on stage at Sala Suggia, at Casa da Música, in Porto, July 9, 2022.

In a production technology class led by teacher Tanya Fernandez, more than 80 costumes were designed and made to match the characters from the various stories featured in the play.

The students made drawings that were transferred to the molds used to mark, cut and shape the fabric into pieces during the sewing process. “The teacher and students showed great dedication and effort, working tirelessly to complete all the work within the deadline”specifies an ad.

Artamega thanked “The opening and availability of the professional design and fashion course at Escola Secundária do Marco to participate in this wonderful project presented at Casa da Música, highlighting the importance of synergy, in this case between schools that are in the same space”ends.

Windows 10 Windows 11 Microsoft novidades funcionalidades

While Microsoft is focused on its new system, Microsoft is committed to ensuring that Windows 11 continues to evolve. It will be supported for a few more years, so it should continue to receive news and improvements.

With what is being developed in Windows 11, there is an opportunity to bring these technologies to Windows 10. This will happen soon with the announcement of a new feature that will improve the printing experience in Windows 10.


Microsoft will mix features

Windows 11 is currently in development for Microsoft. This system is being improved and tries to give users as much functionality as possible, thereby ensuring that this is a modern system, as the best there is.

What seems logical is to combine efforts and include features in both Microsoft systems. So, what's next for Windows 10 is expected and important for its development, both for users and for what it offers them.

Windows 11 will contribute to Windows 10

In particular, Windows 10 will now be able to more precisely control the printing process. This will have a new control that will prevent fingerprints from being created without the user's permission, or from being accumulated without the user's explicit intention.

Windows 10 Windows 11 What's New Microsoft

This control will be as simple as using a PIN to block printing. Only after user authorization will the document be sent to the printer to be converted into a plain sheet of paper.

More news expected in the future

By introducing this new feature to Windows 10, Microsoft wants users to save paper and ink cartridges. At the same time, it provides greater security and guarantees user privacy, especially in environments with multiple printers.

Of course, this will only be the first moment when the functions of the two systems will be combined. Microsoft will certainly increase this proximity and thus guarantee users the maximum even faster.
