Linux / Unix desktop Gnome 40: The next evolution of the Gnome shell

The users of the Linux / Unix desktop Gnome have a few new features: The developers are making extensive changes to the Gnome Shell user interface. The focus is on a new spatial arrangement of the work surfaces, which affects the overview of activities and the behavior of the application launcher. The operating concept thus approximates mobile devices and, according to the developers, is particularly suitable for control via touchpad or hotkeys. However, the new features do not represent a hard break, as with the change from Gnome 2 to Gnome 3.

In a blog post, the developers respond to the feedback from the community with an FAQ and explain the goals of the revision. The developers gave a first insight into the planned innovations in the blog Gnome Shell & Mutter back in December.

New app grid and activity overview In the new design of the activity overview, the virtual desktops are now lined up horizontally and replace the vertical list on the right-hand edge of the screen. The windows have app icons and show the complete window title when you mouseover.

The app overview differs little from the current design in Gnome 3. 38. Existing features, such as arranging applications at will and writing them in folders, remain possible. The grid still lists apps page by page. Users now scroll through them horizontally instead of vertically.

Navigation through the two-dimensional space According to the developers, the adjustments in the design make the Gnome-Shell more intuitive because the horizontal and vertical axes fulfill clear functions. Users scroll horizontally through the workspaces. The vertical axis zooms in and out of the app and activity overview. This arrangement should primarily benefit users who operate the desktop with a touchpad or hotkeys. With Super + Alt + arrow keys or a swipe with four fingers on the touchpad in one direction, the user interface jumps to the desired view.

(Source: Gnome) If a window is moved to another virtual desktop using drag-and-drop, the activity overview zooms out to show all work areas. The new design should be suitable for multi-display setups as well as for the vertical orientation of the screen. The active corner is retained. The developers don’t provide an option to switch between the new and old design. But be open to efforts by the community to keep the classic design via Gnome extensions.

Gnome 40 follows Gnome 3. 38, which removes the previous digit. The new version scheme is intended to avoid bulky version numbers and to clarify the gradual development steps. The project did not use the name “Gnome 4” in order not to arouse false expectations that the new Gnome version already uses the recently released graphics library GTK 4.0.

CES: robot vacuum cleaners think for themselves

Samsung presented the JetBot AI + at the CES, which combines two practical features in one device : The suction bot recognizes obstacles with the help of artificial intelligence and empties itself automatically.

In addition to the almost obligatory lidar sensor for room recognition, the JetBot also features a front camera whose images are used to recognize objects using AI. The aim is to spot and avoid smaller obstacles such as cables, shoelaces or the remains of pets. After cleaning, the JetBot returns to its charging station, which is equipped with its own suction fan and a dust bag. It sucks the suction container of the JetBot empty after every cleaning. According to Samsung, the station’s bag should offer enough capacity for around two months of maintenance-free operation in everyday life.

With its camera and AI, the Samsung bot also detects small obstacles that the Laser sensor overlooks.

Self-emptying and self-finding A charging station that empties the bot is also available with some Roomba models from the manufacturer iRobot – but so far only with the expensive bots. At CES, iRobot is now announcing the European market launch of the Roomba i3 and i3 +. Both models are intended to cover the affordable entry-level range at iRobot. According to iRobot, the i3 costs 90 euros and the i3 + with suction charging station 700 Euro.

What is interesting about the otherwise identical suction bots is that iRobot No cameras or lidar sensors are used for spatial navigation. Instead, both models have an IR sensor on the underside, which optically scans the ground and, together with a gyro sensor and wheel sensors, is supposed to ensure straight-line stability. Together with the IR obstacle sensors in the front, the i3 and i3 + should also find their way around the room and clean all rooms one after the other in parallel lanes. An interesting approach that works without moving – and thus fragile – parts and perhaps causes less concerns about data protection for some customers because of the lack of a camera.

The Roomba i3 + should navigate safely even without a camera and lidar. The base station automatically empties its container after the cleaning trip.

For technical reasons, the i3 and i3 + cannot be sent to a desired location in the apartment, and you also have to do without the no-go zones that can be defined in the floor plan. Since both bots use the thorough AeroForce brush rollers of the more expensive Roombas, some customers might see this as a fair compromise between features and price.

Wet and dry A suction charging station will also be available at Roborock in the course of the year. In addition, the Chinese manufacturer is introducing a fundamental innovation with the S7 presented at CES. As with iRobot vacuum cleaners, the brush roller is now made of rubber and is also spring-loaded, so that it can better adapt to uneven floors – for example when driving onto carpets at an angle.

When it comes to carpets, there is a new feature with the technology called VibraRise: If the mop is installed for the optional wet cleaning and the floor sensor of the S7 recognizes carpet, the cloth is automatically lifted so that it touches the carpet not touched. So you don’t need to define separate no-go zones for wet cleaning in the app. The mop also rises in the charging station so that wooden floors do not swell due to the moisture if the mop is not removed immediately after cleaning.

The mop on the rear underside now vibrates during cleaning to better protect dirt remove. The S7 automatically lifts the mop on carpets.

During wet cleaning, a vibration motor on the mopping module with rapid back and forth movement of the mopping cloth should better loosen dried-on dirt. The vibration intensity can be set between 1650 and 3000 Set vibrations per minute. If the highest level is not sufficient, it can also be specified that each area of ​​the apartment is approached twice.

The S7 is to be used in Germany during the second quarter at a price of 550 Euro come onto the market.

Corona warning app: data synchronization on some Android smartphones disrupted

The synchronization of the transaction data or the key was a while ago …

(Image: heise online)

The users of the Corona-Warn-App may not currently receive the current result of the risk assessment. On Wednesday, several users reported (also in the editorial office of heise online) that the app was not updating the risk status or was no longer comparing the encounter data. The error did not appear on the iPhone.

A spokesman for the software group SAP involved in the development confirmed the problems at the request of dpa: At the moment, the Corona warning app on Android smartphones is “in some cases” not able to carry out a key comparison. “This is currently due to the Exposure Notification Framework under the Google smartphone operating system. We have informed Google about the problem and are working together under high pressure to solve the problem.” SAP developed the app together with Deutsche Telekom.

The Corona warning app recorded so far, according to the Federal Ministry of Health, over 23 million downloads and is estimated by 23 Millions of people actively used.

Data protection or not? Most recently, the CDU politician Friedrich Merz and others had campaigned for a relaxation of the data protection concept of the application in order to provide better data for an effective pandemic Combat to collect. This approach was met with sharp criticism from the Federal Data Protection Officer Ulrich Kelber and the Chaos Computer Club (CCC).

“At no point does data protection conflict with the functionality of the app – with more or less data protection it would work just as well or badly, but by no means better,” said CCC spokesman Linus Neumann. He had already emphasized last year that the overriding of app data protection was nonsense, but that there were other useful extensions, including an option for decentralized cluster recording.

Wide VR support Every beginning is cumbersome Take off in VR: impressive feeling of flight Individual meetings Conclusion Swap a desk chair for a cockpit seat: The virtual reality update of Microsoft Flight Simulator promises to lift the flight experience to a new level. Instead of staring at the flat monitor, you can now sit in the simulated pilot’s cockpit with VR glasses and look around naturally, enjoy the view of the landscape and, of course, control the aircraft at the same time.

While Microsoft’s flight simulation was able to cast its spell over even less ambitious amateur pilots thanks to its realism and graphic splendor, the VR mode has the potential to convey a realistic flight feeling. Getting started is easy with broad support for virtually all common VR glasses on the market. In addition, even players with limited space get a great flight experience right in the middle – without a complex, expensive and space-consuming multi-monitor setup.

However, at first glance the Flight Simulator does not provide the best conditions for VR With. After all, he is hungry for hardware and, in order to avoid nausea, is regarded as a minimum 61 Images per second can be created even with high-end -Graphics cards not reliable. We therefore put on the VR glasses, including an HP Reverb G2 as well as the Rift S and Quest 1 from Oculus, and completed some VR flying lessons.

Which is best for cloud gaming?

Introduction

“Do you guys not have phones?” This has to be the most iconic line when we think of mobile gaming. It’s been more than two years since Blizzard announced Diablo Immortal and these words went viral, yet the game is nowhere to be found. But over the course of these two years the entire gaming industry changed, evolved if you will. Cloud gaming has become possible and it allowed people who have phones to play high-profile console and PC games on the go. And that’s what we want to explore today.

Cloud gaming is like Netflix, but for games. This is what we’d say to anyone asking for the tldr; version. You pay a monthly subscription; you stream the games you play. Simple as that. For this to happen, you would need a gaming controller and a good internet connection, of course. But other than that – you shouldn’t be needing a top-of-the-line smartphone, PC or console to be able to enjoy AAA titles, like say, Assassin’s Creed Valhalla, Cyberpunk 2077, Halo: Infinite, Red Dead Redemption 2, GTA V, Nier Automata, just to name a few.

Currently, there are three major cloud services available to smartphone users – Xbox Game Pass cloud gaming, GeForce Now and Google Stadia. Amazon is currently testing its Luna app, and it will go live later in 2021.

Xbox Game Pass cloud gaming is exactly what the name suggests and is the closest thing to Netflix. You pay a monthly fee, and you have access to 100+ games, which you play on remote consoles. New games are added monthly, but you also lose access to some games each month. All first-party exclusives are always available, of course. See, just like Netflix.

GeForce Now is a bit different. It allows you to rent a high-end PC and play on it while the service streams your sessions to your phone. The fee is lower because you need to buy each game you want to play. It supports games from the game stores operated by Steam, Epic, GOG, and Ubi. So if you already have a disturbingly long backlog of games you’d like to play but don’t have a $4000 PC, this is one very interesting alternative.

Then there is Google Stadia. It is like GeForce Now, except it doesn’t require you to pay for (1080p) streaming if you are playing games you’ve already bought. The monthly fee (Stadia Pro) gives you access to a limited catalog of games to play freely and allows 4K HDR streaming of the ones you’ve already bought. It doesn’t support third-party game stores, though (unlike GeForce Now).

Amazon has a game streaming of its own in the works, too. Amazon Luna is channel-oriented, like a cable service. Your monthly fee gives you access to a certain channel or channels of different games. Currently, it’s still in closed beta test, though.

We’ve tested the three most popular game streaming services, and we had a ton of fun. Check out our impressions start right after the break.

Soundcore Liberty Air 2 Pro with Active Noise Canceling and customizable audio profile with quick hearing test

In the plethora of earphones True Wireless Stereo arriving from China, some products know how to stand out for quality and innovation. The Soundcore brand products belong to this group (as we also told you in this article dedicated to the TWS in-ear headphones), which is part of the extended galaxy of brand of Anker .

The latest novelty took advantage of the virtual CES showcase to show off and promises to stand out from the crowd again. Soundcore Liberty Air 2 Pro are the new proposal of totally wireless in-ear headphones: they offer Active Noise Canceling technology and were created in collaboration with some Grammy Award winning prizes with the intent of providing a color-free sonic response even when the Active cancellation of external noise is activated .

In line with the best products on the market, the active noise cancellation promises to be adaptive and modify its response according to the situations of use, whether you are on a plane, working in a cafe or on a walk around town. Soundcore has also paid a lot of attention to the clarity of telephone calls, integrating 6 microphones for earphones, two integrated in the rod and two in the upper part, to better pick up the voice and eliminate background noise even from phone calls. The other two microphones are placed inside the earphones and allow to eliminate the residual noise that could filter out.

Very interesting then seems to be the HearID function , which with a short ‘exam’ of your hearing allows you to create a customized audio profile . In addition, the app will also provide 22 equalization presets and a customizable equalizer.

The earphones declare a 7 hours autonomy per charge and with the case can offer up to 26 total hours of autonomy . The earphones are already available at the price of 129. 99 ?? in four colors.
