heise + | Sustainable technology: CO2 to stone

To protect the world from dramatic warming, the greenhouse gas has to get out of the atmosphere. Researchers want to turn it into rock.

Veronika Szentpétery-Kessler Tom Green’s name says it all: He green beaches. But not with trees, but with minerals: With the olivines, which are hardly known outside of specialist circles, he wants to capture CO2 from the air on a large scale and in this way slow down climate change.

The head of the non-profit Environmental organization Project Vesta has chosen two neighboring beaches as the first test area at an undisclosed location in the Caribbean. Ground olivine is to be applied to one of them this year. The waves rub the grains together, grinding them into small grains with a large surface. This accelerated weathering creates hydroxide ions that react with the CO2 in seawater to form hydrogen carbonate. This in turn later serves as building material for corals and shellfish. If their shell then sinks to the sea floor, it becomes limestone and other rocks, which store the CO2 for eons. It would only be free through geological activity.

“Reducing CO2 emissions will not be enough, we also have to remove the gas from the atmosphere,” says Green. Many researchers and the International Energy Agency are convinced that even if no additional CO2 were emitted into the atmosphere, global warming could no longer be stopped. Also the biologist, who after 18 years ago wanted to get involved in various tech companies for climate protection, after switching to technologies that enable such so-called negative emissions.

heise + | The construction kit for the Stepcraft M.700 milling machine in the test

Stepcraft 2000 introduced three new machines: The M. 500, M. 700 and M. 700, where the number stands for the rounded length of travel. In contrast to the D-series, the new milling machines no longer use simple rollers that run directly on the aluminum profiles, but high-quality linear rails made of polished steel, and ball screws can also be ordered at an additional cost.

The extensive Stepcraft system accessories can also be used with the new machines: For example, a 3D print head or an engraving laser are available that can be installed instead of the milling motor. There is an oscillating tangential knife for processing rubber and leather, a drag knife for plotting writing foils and a hot wire insert for cutting styrofoam – and much more.

Our test device, the M . 700, reached us as a kit – a carefully packaged, 40 kg heavy 3D puzzle on a pallet. So we already had the opportunity to work intensively with the machine during assembly: The assembly instructions include merciless 96 Pages with which the manufacturer’s statement “built in a few hours” as a euphemism for “4 days of work at a time” relativized.

heise-offer:-extended:-early-bird-discount-for-the-bettercode-()-c-++-20-until-january-8,-2021

heise offer: Extended: Early bird discount for the betterCode () C ++ 20 until January 8, 2021

Due to the start of the nationwide lockdown and the associated pre-Christmas stress, also among developers, the betterCode () organizers have decided to open the early bird window further: Tickets for the online event for the new standard C ++ 20 are now a little longer, namely until January 8th 2021.

Live from Germany, Switzerland and New York At the 21. January 2021 organize heise Developer and dpunkt.verlag together with Bjarne Stroustrup, the inventor of C ++, and other experienced experts an online day on C ++ 20. All lectures will take place as a live stream in the browser, Bjarne Stroustrup is connected to the event from New York and will answer questions from the audience about C ++ in the moderated final round. This AMA (Ask Me Anything) session takes place in English, the questions can be asked in German. Bjarne Stroustrup’s keynote is in English, the rest of the conference will take place in German.

What do the new ones bring Features? Where does the C ++ programming language come from, which design principles it follows and what C ++ is about 20, explains Bjarne Stroustrup in the keynote. Members of the ISO standard committee then present the individual features: Concepts as the next generation of templates and how developers use them themselves, explains Andreas Ready. Daniela Engert goes on the trail of the C ++ modules and provides an introduction to the new feature. Detlef Vollmann presents the coroutines: He teaches developers how to use coroutines in C ++ for multithreading. Nico Josuttis introduces C ++ libraries, especially the ranges library newly introduced in C ++ 20. Peter Sommerlad offers a practical deepening in the type system in modern C ++ with his lecture on Strong Typing. All lectures are firmly anchored in practice with concrete examples.

At the pulse of C ++ development After each lecture, the participants can talk extensively with the respective experts in a Q&A session before the program continues. There is an exchange between the participants and speakers in the chat and by direct message, in the Q&A room participants can also connect with sound and images. In addition to the conference day, Nico Josuttis and Rainer Grimm will each offer a full-day workshop in February 2021. During the practical day on best practices for C ++ and the crash course C ++ 20, C ++ developers can develop their practical skills under expert guidance.

An early bird rate applies until January 8th 2021 for tickets and combination tickets for the C ++ event. Participation in the conference costs in the early bird phase 21 euros, afterwards 199 Euro. The workshops cost individually 449 Euro (all prices plus 19% VAT), there are inexpensive combination tariffs and, on request, group tickets for teams. Schoolchildren and students receive a discount. The event team answers inquiries.

About the process On the betterCode website () C ++ 20 is the program with information on the process, the speakers and the individual lectures. Interested parties will also find further links and the current status of planning there. Afterwards, the participants will receive a video recording and the presentations.

Game Development: Unity 2020.2 updates tools for better workflows

Unity, the company behind the game engine of the same name, has released version 2020. 2. In addition to innovations for the graphic rendering, the development team behind the game engine is also updating its tools and revising the artist, team and editor workflows. The release also focuses on increasing performance.

Unity 2020 .2 is the second of the Tech Stream releases planned for this year. In January 2020 Unity announced that it would deliver two instead of three releases per year. This is associated with longer alpha and beta phases to ensure a more stable core engine. Further functions are to follow as modular packages.

New for the URP and HDRP pipelines beginning of April 2020 Unity had published a timetable for the year 2020. This included changed offers for live content as well as information on the Unite Now digital program series. The focus was on stability, performance and ensuring smooth workflows. This is where Unity 2020. 2 connects. The update extends the Universal Render Pipeline (URP) with new functions and brings it closer to parity with the built-in render pipeline. Screen Space Ambient Occlusion (SSAO) is intended to improve the quality of the ambient lighting in the scene. The development team behind the game engine is introducing a new complex lit shader that allows developers to reduce the size in build data and load time. In addition, with the update it is possible to use Clear Coat Maps to simulate materials such as car paint.

Also the High Definition Render Pipeline (HDRP) With Unity 2020. 2 new tools have been added to help developers debug the lighting. In addition, the development team worked on the decal system. Path tracking supports mist absorption and subsurface scattering for organic materials. A new mode for depth of field can generate path-traced images with high-quality defocus blur (unsharpness). Unity 2020. 2 has an HDRP sample scene in its luggage, which already contains some setups of the physically based light intensities. This should give developers a good starting point for creating realistic scenes with HDRP.

Updated tools for workflows The Current version of the game engine has been revised for all artist workflows. The updated tools give developers the ability to create cinematics and other video and film content. For example, with the revision of the performance of the graph editor, the update extends the shader graph with new functions, which in turn should improve the workflows for technical artists. The VFX has been expanded to include output events, which should enable users to synchronize lights, sound, physical reactions or gameplay based on spawn events via a delegate interface in C #.

But not only that The update focuses on optimizing artist workflows. There are also innovations for work processes in teams and in the editor of the game engine: Unity Hub version 2.4.2 brings, for example, revised workflows for managing projects, downloads, Unity editor versions and modules. Among other things, a new feature is a quick search with which developers can search through all scenes and prefabs of their projects at once without being limited to open scenes.

Unity currently recommends version 2019 Long-Term Support (LTS) for developers looking for maximum stability. Unity announces the next LTS version, Unity 2020, for spring 2021. Those interested can find more information about the current release of the game engine in the post on the Unity blog.

Bugatti Royale: quite literally the Bugatti of active speakers

(Image credit: Bugatti)

It’s not the first time a high-end audio brand has collaborated with an aspirational automobile manufacturer to produce audio kit not intended for use behind the wheel of your hypercar – in the past few years Porsche has teamed up with KEF to produce headphones and wireless speakers and Klipsch worked with McLaren on a set of sports in-ears to name just two. But if ever a set of monolithic floorstanders harked back to the 1930s supercar they’re named after, its the new Bugatti Royale. 

Bugatti is collaborating with premium German audio firm Tidal (no relation to the music streaming service) to create “the Bugatti of home audio,” and it’s kicking things off with this remarkable set of speakers.

Bugatti connoisseurs will almost certainly know that the French car manufacturer produced only six of its huge Type 41 motor vehicle (better known as the Royale) between 1926 and 1933, a car intended to be the biggest, most luxurious, most expensive in the world. And only four of those were actually sold. Obviously, both Tidal and Bugatti are hoping to avoid a similar situation with the new Royale speakers, but there are several more positive similarities. 

Tidal is offering two limited-edition versions of the Royale speaker – Edition Blanc and Edition Noire (yes, black and white) but there will apparently be an almost limitless selection of customisation options for buyers, similar to the way that Bugatti allows its customers to personalise their hypercars in various veneers and finishes. Buy a set of Royales, and you’ll be able to pick from various materials, with carbon fibre, leather, precious metals, dark aluminium and polished stainless steel on the menu – but not cheese. The speakers are available in one of two themes – Monocoque or Duotone cabinets, and piano finishes are also available.

The Bugatti logo also adorns the speaker and ‘Tidal for Bugatti’ is branded on the back. Each Royale stands almost 1.5m tall and weighs a whopping 160kg – about as heavy as a reindeer.

Under the bonnet, each speaker comes with four long-throw subwoofers and two front-firing woofers with aluminum diaphragms. The Royale also features one high-efficiency diamond tweeter (the same as those found in the cars) and one high-efficiency ceramic midrange driver, though customers can upgrade the latter to a diamond one.

Interestingly, the Royales are active speakers, meaning they house what Bugatti is calling “extremely powerful amplifier channels” inside the cabinets. The matching Bugatti-branded music controller (pictured) will allow you to connect to your sources, including music streaming services and TVs.

And the price? It hasn’t been disclosed; a sure sign that if you need to know, you can’t afford them. A fee involving six figures is likely…
