Computer simulations have shown that global warming will lead to regular super downpours

Global climate change will provoke regular powerful downpours. An article about this is published in Geophysical Research Letters.

Computer simulations have shown that global warming will lead to regular super downpours

This conclusion was made by specialists from the University of Copenhagen and the Danish Meteorological Institute when studying a super shower that passed over Copenhagen in July 2011. The authors of the work decided to recreate it in a computer simulation to find out what caused it. The simulation was run 13 times, once for each level of global temperature, namely: -1 degrees Celsius relative to the norm (pre-industrial era), 0 (norm in 2011), and +1, +2 and +3 degrees Celsius . The distance between the data points in the model, known as the grid size, was about 2.5 kilometers (this can be roughly considered model pixels). In comparison, global climate model grid points are typically at least 50 kilometers apart, so the new simulation can be considered extremely accurate.

It turned out that the higher the temperature was, the more abundant the downpour became and the more powerful the flood it caused. In particular, if the climate had not warmed by one degree over the 20th century, the chance of the formation of a super shower in 2011 would have been half as much. The authors of the paper believe that this fact should be taken into account when planning climate policy.

Logitech is also bringing a new blueberry color to the K380 Multifunction Keyboard for Mac, which works with Mac, iPad, and iPhone. It is offered for $40

Logitech has announced a $100 MX Master 3S mouse that allows you to scroll 1000 lines per second and also has an adjustable DPI level (from 1000 to 8000). The mouse received quiet buttons and can connect to three devices at the same time.

Black and White LCD Wi Fi and 249 Mechanical Keyboard Pre Order

Modern PCs and smartphones have long become universal devices that allow a lot. But AstroHous seems to think that dedicated systems are better. The developers have introduced a portable device called Freewrite Alpha, which is designed for writers. This is a kind of modern “reissue” of electric typewriters and word processors.

Black and White LCD, Wi-Fi, and $249 Mechanical Keyboard Pre-Order: Unique Writing Computer Introduced

The novelty is equipped with a monochrome LCD display measuring 6.5 by 1 inch, which is enough to display from 2 to 6 lines of text at a time, depending on the font size. Alpha also has a full-size mechanical keyboard on Kailh Choc V2 switches, a USB-C port for charging a 4200 mAh battery, an 802.11b/g/n Wi-Fi adapter, and some modern features, including basic text editing, cloud sync and autosave.

Note that Freewrite also has more advanced models with E ink screens, but the price is higher. The Alpha is available for pre-order for $249 and will retail for $349 in Summer 2023.

The main advantage of the device can be considered its instantaneous activation, which is sometimes important for writers. There’s also support for Freewrit mail and third-party services, including Dropbox, Google Drive, and Evernote.

The design of the Freewrite Alpha is inspired by classic devices from the 1980s and 1990s such as the AlphaSmart, Cambridge Z88, and TRS-80 Model 100. AstroHous plans to only sell English layout versions at this time, but other language options may be added if there is demand. .

The new space computers will be 100 times more powerful

NASA has chosen a new processor architecture that will be used to create chips for future space missions.

The new space computers will be 100 times more powerful than the current ones.  NASA selects architecture and manufacturer for next-generation space processors

The management opted for the RISC-V architecture and, in particular, SiFive, which develops the corresponding processor cores. The company announced that the new High-Performance Spaceflight Computing (HPSC) processor, which will be used in virtually all NASA missions, including lunar and Martian missions, will use the eight-core SiFive Intelligence X280 RISC-V vector core and four additional SiFive cores RISC-V. As a result, this should provide a 100-fold increase in the computing power of new space computers compared to current generation solutions.

Significant performance increases will help open up new opportunities for various elements of missions, including autonomous rovers, imaging, spaceflight, guidance systems, communications, and so on.

It is still unclear when the first devices based on the new processors will be launched. Given the timing of the development of space missions, it is likely that at least a few more years will pass.
