Acer yesterday unveiled a very interesting product, the Predator GD711 projector, which, in addition to being able to project 4K content, supports all next generation consoles and is even capable of projecting an incredible 240Hz image if you have a PC capable of it. …

Acer Predator Projector: Why Play on a Monitor or TV?

So, for the most fanatical gamers, we have a video game-only projector, capable of 120Hz or 240Hz in 1080p resolution, and capable of achieving the always-desired 4K.

In terms of brightness, we have 4000 lumens, as well as high contrast, HDR10, etc … In terms of screen size, Acer claims the ratio is 1.22, which in turn means 100 inches. by moving the projector just 2.7 meters away from the wall or screen. On top of that, we also have a 10W speaker, controller and design for super gamers.

The lamp of this product, according to the brand, can withstand about 30 thousand hours of use, so with that it has a lot of gambling ahead of it.

Interestingly, we also have 3D support, but the glasses are sold separately. By the way, about the sale separately … This projector will hit the shelves in December next year at a price of 1499 euros.

So what about you? Do you prefer a projector, TV or always reliable monitor? The market is interesting, but it always raises a lot of doubts. Share your opinion with us in the comments below.

Lei Jun confirms the 'rare' feature of Xiaomi Redmi Note 11 smartphones

The Chinese manufacturer, led by Lei Jun, is preparing to unveil a line of smartphones. Xiaomi Redmi Note 11 next October 28th. However, via the Chinese social network Weibo, the CEO confirmed the presence of a rather rare asset at the end of 2021.

In particular, both Redmi Note 11 will be equipped with an audio port. Jack 3.5mm for easy headphone and wired headphone use. Therefore, as Lei Jun says, “There are several smartphones that support Jack 3.5mm “, which is the Note 11 range.

The Xiaomi Redmi Note 11 lineup will go on sale on October 28.

Detail of the top edge of the Xiaomi Redmi Note 11 smartphone.

First, we will have at least two new Android smartphones. Namely, Xiaomi Redmi Note 11 and Xiaomi Redmi Note 11 Pro, two mid-range models. Their trump card in 2021 will be value for money, and for that they will be well equipped.

However, we may also have Redmi Note 11 Pro + (Plus), possibly an exclusive from the Chinese online store JD.com. We’ll get confirmation on October 28, but given the brand’s history, at least two of the aforementioned versions will arrive in Europe in due course.

In any case, the CEO himself has confirmed that the entire Redmi Note 11 lineup will have this port, which is a rarity in 2021. By the way, above we can see the details of the top edge of one of these future smartphones and its elements.

The guarantee was given by Lei Jun, the current CEO of Xiaomi.

This was announced by the company’s CEO Lei Jun on the Chinese social network Weibo.

In more detail, on the upper end of the smartphone, we see the door in Jack an audio port (3.5mm), an infrared port (infrared) for remote control, such as a hole for an additional microphone, and a speaker grill with JBL customization.

It also confirms that at least the top models will have dual speakers, and JBL’s experience lends the wisdom for better sound quality. In addition, the similarities of the next Android smartphone are confirmed.

In particular, the angular lines, as well as the general shape of the rear camera module in smartphones Xiaomi Redmi Note 11. There, the first camera will be more important, accompanied by at least two other photo modules.

Next-generation mid-range smartphones by 2021

The poster for the presentation of Xiaomi Redmi Note will run from 11 to 28 October.

The presence of a 3.5mm audio jack port gives users the ability to connect their headsets headphones and earphones with cable. What is important and appreciated above all by those who play on the phone, avoiding delays or delay

That is, the gap between the displayed image and the sound reproduced by in-ear headphones, earphones and / or headsets. That in wireless devices is more prone to noticeable and catastrophic lag in gaming situations.

There is no more reliable option for this than traditional wired headphones. Especially when these Xiaomi phones also carry the JBL quality mark clearly visible on their body.

Now it remains to finally wait for the official presentation of these new Android smartphones on October 28 in China.

McCree, de Overwatch, agora se chama Cole Cassidy

because accusations of harassment and discrimination on Blizzard became publicly available, some players requested the character Jesse McCree from Overwatch, change your name. The company then complied and said it would announce a new nickname for the hero to “better represent what Overwatch stands for.”

The company publicly announced today that the culprit is now called Cole Cassidy… Overwatch’s official Twitter account wrote:

“The first thing a renegade loses is his name, and he gave up a long time ago. To run away from the past was to run away from myself and with each passing year the distance between who he was and what he became only widened. But in every cowboy’s life there comes a point when he has to stop and take action. To make this new Overwatch better, to make things better, he had to be honest with the team and himself. The cowboy who was once left at dusk and Cole Cassidy met the world at dawn.

A few weeks ago, the company announced that playable characters would no longer have employee names, and also promised to be more careful when adding actual links to the game to confirm that this is a fictional universe and that creating it is work. in a team.

Activision Blizzard is currently pursuing a series of lawsuits that began in July after the state of California filed a lawsuit against the company over allegations of workplace discrimination and sexual harassment.

Massachusetts Institute of Technology created a “cheetah robot” and taught it to jump

Massachusetts Institute of Technology created a "cheetah robot" and taught it to jump

Do you know that Massachusetts Institute of Technology (Massachusetts Institute of Technology) is there a cheetah robot? So did we, but we not only found that the project was real, but the same cheetah robot learned to jump. And you thought that humanity had stopped in robotic sniper dogs, Definite?

Read it too

publicity

The novelty comes from the Massachusetts Institute of Technology itself, because humanity obviously has the right to brag. creations that may one day kill her… In an official statement from the institute, the researchers say that “four-legged robots have been inspired by the movements of cheetahs and other animals, making tremendous progress, but they still lag far behind their mammalian cousins ​​when it comes to rapidly changing movements. lifting environment “.

And yes, they shot a video:

“Under these conditions, you need to use [um sistema de] night vision to avoid accident. For example, walking through a hole can be difficult if the robot cannot see it. While there are some methods of incorporating night vision into leg movement, most are not highly recommended. for flexible robotic systems– said Gabriel Margolis, a graduate student at MIT’s Computer Science and Artificial Intelligence (AI) Laboratory.

To get around this difficulty, Margolis and his team have developed a system that “improves the speed and maneuverability of robots on their feet as they jump over chasms in the terrain.” This system is split into two parts: real-time processing of the footage with a camera mounted on the front of the robot, and another that translates this information into instructions that tell how the robot should move.

In short: the system sees the hole ahead and teaches the platform on which it is installed to jump competently. And the Massachusetts Institute of Technology found it interesting to put all this in a robot named after an animal that runs at speeds up to 130 km / h and strangles prey with neck bites.

Do you know who doesn’t run at 130 km / h? Right: we

The new method proved to be useful because, unlike other platforms, it does not require preliminary mapping of the area to be covered, which theoretically allows the “cheetah robot that can jump” to move anywhere. The idea is that in the future this platform can be used in response to emergencies in isolated areas or when delivering consumables to hard-to-reach places.

The control of this system is applied artificial intelligence (IA) to process video captured by the camera in real time. According to the Massachusetts Institute of Technology, several “blind” forms (which do not use video) of this application have very robust features, but one difficulty is that the landscape must be continuous without changes in topography. Others depend on the previous mapping, which “trains” the algorithm before actually taking the route.

To get around this, Margolis developed a hybrid format: while the parallel system takes care of capturing video and controlling the joints of the robot, the AI ​​focuses on processing incoming images and “learning” to avoid obstacles when using all directions – not only on the sides and diagonally (implying bypass only when walking), but also vertically (which includes the ability to jump).

To test the effectiveness of the project, the researchers ran simulations based on different types of terrain, through trial and error, setting the evaluation metric as “reward.” The system quickly figured out which actions would bring you the most points and started accepting them by default.

Think of it this way: when you teach a pet to sit down, he takes pleasure. If he sit and roll, two snacks. Etc. But instead of your mongrel, this is a robot with a neural network in its head.

And this neural network made the “cheetah robot that learned to jump” successful in 90% of the tests, outperforming unitary control systems.

“A new feature of our system is that it corrects the gait of the robot,” said Margolis. “If a person is trying to jump over an abyss that is too wide, he can start with a running start to pick up speed, and then put both legs together to make a very powerful jump. Likewise, our robot can customize time and the length of time your feet are in contact with the ground to better traverse the terrain. “

According to Margolis, the current project has only demonstrated that the system works, and it is (presumably) still a long way from practical application. In the future, the MIT team intends to use an internal computer. with more processing power to transmit these readings directly through the platform. In addition, they want to improve the control of the minority so that it does not lose efficiency at different light intensities.
