AI: fake faces increasingly difficult to identify

fake ai generated faces

Fake faces, created from scratch by artificial intelligence, have fewer and fewer flaws, making them sometimes undetectable to a human.

The “fake faces” or synthetic faces are now more imperceptible to a human being. A study conducted by the University of Texas asked several hundred people to distinguish real people from faces generated by an algorithm.

Fake AI generated faces are harder to recognise than ever!

The study’s process is interesting. A first group of 315 subjects was asked, on two portraits next to each other, which one was fake. The same request was made to a second group of 219 people who were briefly trained to identify fake faces, including the defects left by the artificial intelligence in certain places. A third and final group of 233 participants rated the reliability of the 128 images presented to the first two groups, on a scale of 1 to 7.

In their answers, the subjects of the first group obtained less than one correct answer out of two (48.2%). For the second group, better prepared, the percentage increases slightly to 59% of correct answers. Finally, the ratings of the last group give on average a higher reliability rating to the fake faces (4.82) than to the real people (4.48).

“We’re not saying that every image generated is indistinguishable from a real face, but a significant number of them are,” laments study co-author Sophie Nightingalen. She is also concerned about the ease of access to the technologies that allow the creation of these synthetic portraits. She is not wrong.

Almost two years ago, during the presidential elections in the United States, a 17-year-old American boy created a fake profile of a fake candidate on Twitter. The mysterious Andrew Walz had a profile picture from the website thispersondoesnotexist.com, which, as its name suggests, presents portraits generated by artificial intelligence. Twitter eventually certified his profile before being alerted by the media coverage of the deception.

In their conclusions, the two co-authors encourage “those developing these technologies to ask themselves whether the associated risks outweigh the benefits. If so, then we discourage the development of a technology simply because it works.”

3G is gradually disappearing in the United States

3g discontinued in the US

On February 22, the first American operator, AT&T, closed its 3G network in favor of 4G and 5G.

It was written since 2019, AT&T closed its 3G network on February 22 in the United States. T-Mobile and Verizon are expected to follow later this year. This decision taken by operators to focus on 4G and especially 5G networks does not please everyone. Several devices, risk not working anymore, across the Atlantic we even talk about an “alarmaggedon”.

According to AT&T, 1% of mobile data traffic goes through 3G

This barbarism reflects the alarm industry’s concern. One industry group estimates that two million devices are at risk of failing. In another area, Axios is relaying an alert from The School Superintendents Association that 10% of public school buses will lose their GPS and communication systems.

In San Francisco, transit riders have been informed that all 650 real-time bus shelter displays will cease to function.

AT&T tried to reassure everyone. The operator claims that less than 1% of mobile data traffic goes through 3G. Two million free or discounted 4G LTE phones have been distributed to replace 3G devices. The company insists, the country’s phone coverage will not be affected.

On the subject of “alarmaggedon,” AT&T is more offensive. The carrier reports that the nation’s largest alarm company has successfully updated all of its devices, including a device it designed. For those who didn’t manage to do so, the pandemic would be a good thing, because they preferred to install new ones than to update the old ones.

The US authorities are keeping an eye on things, but they are letting it happen

Nevertheless, when contacted by Axios, a senior White House official said he was monitoring the operators’ transition plans and shared “concerns about the potential impact of these plans on the function of home security and medical alert devices.

The alarm industry’s communications committee asked the Federal Communications Commission (FCC) to delay AT&T’s plan until December, without success. The agency in charge of communications probably has no intention of throwing a wrench in the works after successive postponements of the 5G rollout because of the disruption to aircraft.

FCC Chairwoman Jessica Rosenworcel, a Democrat, said Feb. 18, “I think we’re on track to make this transition happen with limited disruption.” T-Mobile has scheduled its 3G network to shut down on July 1 and Verizon by the end of the year without further details.

In Europe, too, the 3G network is approaching its twilight. Germany and Denmark have put an end to it and other countries are expected to follow. The website 01net has looked at the French case. It appears that the French operators are reluctant for the moment, because there are still many 2G and 3G users in France.

Apple finally making significant progress on its VR headset project

apple vr headset

The object of many rumors for several years, Apple’s virtual reality headset would gradually begin to materialize internally. According to information from the media DigiTimes, this future product has already passed its “second phase of validation and technical testing (EVT 2)”.

At this stage, and if DigiTimes is right, Apple is no longer working on prototypes, but on a headset that is gradually approaching its final version. As ArsTechnica points out, “EVT 2” indeed refers to a stage in Apple’s journey in designing new devices. The firm starts by working on prototypes before moving on to the first EVT (engineering validation testing) phase, followed by the “EVT 2” phase, which interests us today.

This is an important marker for the progress of Apple’s work on this headset: after the engineering validation (EVT), comes the design validation, followed by the production validation… which allows, as its name indicates, to start the mass production of a finalized product.

A VR headset expected at the end of 2022

Still according to DigiTimes, the Apple headset could enter the production phase in August or September, for a launch in late 2022. Note that Mark Gurman, journalist for Bloomberg, had however evoked a delay of the device somewhere in 2023.

The analyst Ming-Chi Kuo, for his part, had maintained that a marketing in 2022 was still possible. We will have to wait a few months to know for sure.

In any case, the first Apple headset should mix virtual and augmented reality by relying on advanced components. We’ll find 4K screens, multiple sensors and an M1 processor that develops a computing power equivalent to that of the latest MacBook Pro.

The idea would be to make this product very powerful and autonomous (it would not need to be connected to another device to work) in order to target the professional world, at least at first.

Amazon takes sanctions against Russia

Amazon takes sanctions against Russia

The American e-commerce giant announced on Tuesday, March 8 that none of its products will be delivered in the country of Vladimir Putin.

Jeff Bezos’ company is the latest major American technology company to take sanctions against Russia and Belarus. While not necessarily a major player in the country, Amazon decided to suspend deliveries and block registrations to its cloud service, Amazon Web Services.

No more delivery or cloud in Russia

Over the past few days, there has been one disengagement after another from many US technology companies. Most Silicon Valley companies have cut their ties with Russia. Oracle, Intel, Apple, Google, Airbnb, Microsoft and AMD have decided to suspend their activities on Russian territory. Measures taken in line with the sanctions imposed by the U.S. government.

It is now Amazon’s turn to comply with government directives. The e-commerce giant announced on Tuesday March 8 that none of its products will be delivered in Vladimir Putin’s country.

A decision taken in response to the invasion of Ukraine, which forced the group to “take additional measures in the region”. In its press release, the company of Jeff Bezos explains that it has “suspended the shipment of retail products to customers based in Russia and Belarus. The Seattle firm even decided to go further by suspending the accounts of its streaming service Amazon Prime, to all Russian subscribers. Amazon adds that “we are no longer taking orders for New World, which is the only game we sell directly in Russia.

Amazon has never really tried to develop the Russian market

It is important to note that Amazon’s business is much smaller in Russia than in the European Union. It does not have a logistic site in Putin’s country, as it is the case everywhere in Europe, nor a website, but the company still delivered to Russian customers who placed orders from other websites. In Russia, there are other major retail players. Local competitors like Wildberries or Ozon. Indeed, the high import taxes make Amazon’s products uncompetitive in Russia.

Same thing for Amazon Web Services, the company’s cloud service. The American firm specifies that “we have no data center, no infrastructure or office in Russia. Our policy has long been not to work with the Russian government. Most AWS customers in the country are in fact local subsidiaries of international groups.

This decision to stop all the group’s activities also follows a request from the Ukrainian Deputy Prime Minister, Mykhailo Fedorov, who asked Amazon to suspend access to AWS services in Russia, to “support a global movement of governments and large companies opposed to the invasion of Ukraine.

Dell: growth at all costs in 2022, with record revenues

101.2 billion dollars in revenues, for a 17% increase in one year, is what comes to mind when reading Dell’s financial results for its 2022 fiscal year. The Texas-based giant has thus signed a record year, marked by growth in all its divisions. That said, the PC branch of the Round Rock manufacturer is particularly celebrating with record shipments, Dell is pleased with the first lines of its statement.

“Fiscal 2022 was the best year in the history of Dell Technologies. We achieved more than $100 billion in revenue and grew 17%, which is a significant achievement and ahead of our long-term growth targets,” commented Jeff Clarke, vice president and co-chief operating officer of Dell Technologies, among others, as quoted by Le Monde Informatique.

A very lucrative year 2022 for Dell

In terms of operating income, Dell is also very well off with 4.7 billion dollars for an increase of 26% compared to 2021. When we go into detail, we see that all divisions of the American giant are in the green, with a growth of 27% to $ 61.5 billion for the Client Solutions Group (including 17.3 billion and +26% in the fourth quarter alone).

The Infrastructure Solutions Group, for its part, will have total revenues of $34.4 billion for fiscal year 2022 as a whole. To a lesser extent, Dell’s server and networking business is also on a roll, with +7% (YoY) and $4.7 billion in revenue; while storage products brought in $4.5 billion in revenue for Dell over the past year.

However, this virtuous dynamic has not been observed at VMWare. Separated from Dell a few months ago, the company has posted an increase in revenue (+9% to $ 12.785 billion), but a net income that fell by 11% to $ 1.82 billion, says Cnet.

Nintendo switch finally allows to connect your bluetooth headset

The update 13.0 of the Nintendo Switch allows to connect bluetooth headsets. No need for a dongle.

This is a feature that we were many and numerous to expect since the launch of the nintendo switch in 2017. The console is equipped with bluetooth and wi-fi as standard, but it was impossible to pair a bluetooth headset until today.
If you used to use a wireless headset with your smartphone, pc or tablet, impossible to use it on your nintendo switch. A shame for a mobile and modern device.

Bluetooth audio in listening mode only

This is what nintendo announced very soberly by a tweet in the night of 14 to 15 September. With the 13.0 update of the system of the Nintendo Switch, we can now pair headphones or bluetooth headphones.

There is however an important nuance that must be understood. Here Nintendo offers only bluetooth audio in listening, without the possibility of using the microphone of the headset. For voice communication, we will still have to find alternative systems.

Nintendo also warns that latency may be a problem in bluetooth. The latency inherent in the use of Bluetooth is a well-known problem with Android products.

Nintendo is ahead of its competitors

The Nintendo Switch was often criticized for the lack of Bluetooth audio connection, because it is a portable product where this synchronization is very practical.

However, it should be remembered that this is a classic situation on the game console market. Indeed, neither the playstation nor the xbox offer a bluetooth audio connection.

It is even more ridiculous in the case of the playstation that sony is one of the best manufacturers of bluetooth headsets, and that the dualsense controllers use bluetooth to connect to the console, jack port integrated into the controller included.

Crypto-currency mining: what is it?

bitcoin hash rate

Cryptocurrency mining is the most recent growing trend. From Bitcoin to Ethereum, everyone who knows the concept of crypto-currency mining wants to earn as much money as possible. And for those who have not yet devoted themselves to the art of crypto-currency mining, we have published the ultimate beginner’s guide to help you unlock its secrets.

First of all, mining is an intensive computation work that requires a lot of processing power and time. Cryptomoney mining is the act of participating in a network of cryptomoney distributed by peers in consensus.

The origins of mining

We like to believe that to know where you are going, you need to know where you come from. And the cryptocurrency mining, although relatively new, has come a long way since the first Bitcoin in 2009. Bitcoin mining was the first crypto-currency mining that people knew, and today there are more than 800 crypto-currencies that can be mined and exchanged.

Current knowledge

If you don’t know the basics, you may limit your growth. When it comes to crypto-currency mining, it is important to know that there are 2 types of currencies – the loser and the pre-miner. Most currencies are shabby by their very nature because they are based on a blockchain (a chain of blocks).

However, some currencies that have been mined by insiders are also available for sale in various cryptographic currencies. It is these currencies that benefit insiders. Basically, proof-of-work currencies (PoW) are those that can be mined while proof-of-stake currencies (PoS) are those that are pre-mined.

Trust in the future

15 years ago, whatever you did in the Internet field could make you millions. Today, with good advice, the same could happen with crypto-currencies.

From Bill Gates saying “The future of money in this world is crypto money” to Chris Dixon saying “There were 3 eras of money – the one based on raw materials, the one based on politics and now the one based on mathematics”, we believe that crypto money will change the way the world works, and we explain here the mining of crypto money to make your life easier.

Crypto-currencies attracts crowds to the digital world and the crypto-currency mining gives you the right to your turn to perhaps make a fortune on these roller coasters. At the end of this rainbow there is really a golden pot waiting for you – in the form of digital tokens, contrary to legend. And we are happy to be your catalyst in these processes.

How to get rich with crypto-currency mining

You have sweaty palms and you’re nervous? It’s time for you to put all this behind you. We provide you with a detailed guide on how to exploit the Top 5 crypto on the market, how to mine them and the rewards involved. Ready? Ready?

Bitcoin mining

The queen of crypto-currencies had to be the first choice without a doubt. After all, bitcoin mining is the oldest (and still the most widespread) form of crypto-currency mining.

Bitcoin mining is intentionally designed to be difficult and resource-intensive, so that the number of blocks finished each day by miners remains stable.

Why are cryptocurrencies mined?

Governments and legal entities control national currencies. National currencies are therefore part of a centralized economic system. While cryptomones are decentralized currencies. No legal entity controls cryptomonnaies.

It is the users who decide the fate of a cryptocurrency. Some of the most popular crypto currencies are Bitcoin, Ethereum, Ripple, Bitcoin cash, etc. For acheter du bitcoin et des cryptos monnaies.

As there are no centralized bodies such as banks in cryptocurrencies, there is no need for private registers. Instead, there is a public register, which is unique to each currency. This public register is called the blockchain.

In a centralised economic system, it is the duty of a bank to update its customer register. But in the cryptocurrency system, there are no banks or third payment operators. So we need someone or something that can check the transactions and add them to the blockchain. It is the work of minors.

Nokia puts operators on the road to 5G by boosting 4G performance

fmasgosbngdngierbgiosnvojnsppsss

Nokia expands its comprehensive portfolio of broadband technology products and solutions to provide operators with greater flexibility to meet consumer demand and improve the performance of mobile networks as they evolve to 5G.

fgsgdbnnnnnnmooooioiiAs mobile broadband traffic continues to grow, operators want to improve network performance where they see high demand – typically first deployments in dynamic urban centers.
Increased capacity, higher throughput and variable network latency are required to meet consumer, business and Internet of Things (IoT) demand and ensure a smooth transition to 5G. To this end, Nokia has defined a viable network evolution strategy that will enable operators to leverage existing investments and maximize resources such as spectrum, to increase performance where and when needed in the network.

To do this, Nokia is expanding its portfolio of AirScale distributed RF heads, enabling operators to increase maximum cell performance and capacity while reducing space requirements at cellular sites via new single- and dual-band FDD-LTE and TD-LTE radio solutions.

These solutions are based on carrier aggregation technologies, MIMO 4×4 and Beamforming 8×4. They also meet the demand for higher transmission power, expand support for frequency bands and simplify network deployments.

To intensify the deployment of heterogeneous networks and increase the coverage and capacity of the most frequented locations – especially in very dense urban environments – operators will have to deploy a new wave of small cells. Self-Organizing Network (SON) features on Flexi Zone small cells will simplify ultra-dense network deployments, providing solutions to problems caused by the reduced distance between existing and new small cells, and ensuring continuous optimization as densification continues.

Nokia has extended its SON functionality on its Femtocell product line to ensure smooth integration and increased performance in heterogeneous networks when unloading traffic on the macro network.

5g ready networks

The new features of the first Nokia Flexi Zone CBRS small cells, which support Spectrum Access Server (SAS) and Citizen Broadband Radio Service Device Proxy connectivity, will provide operators with new options to increase coverage and capacity, especially inside buildings. CBRS Flexi Zone small cells can be used to deploy host-independent capabilities, allowing operators to lease capacity to other suppliers in shopping malls, hotels and office buildings where space is limited. By FCC requirements, small cells will be able to effectively communicate with the SAS server to verify that the network uses only the available shared CBRS spectrum.

To ensure the flexibility of wireless backhauling in heterogeneous and ultra-dense urban networks – which use microwave beam transport to connect small cells to fiber access points – Nokia Wavence Microwave solutions now support operator SDNs. Operators will benefit from new intelligence and a new level of automation: faster start-up of virtual network functions and adaptable settings to accommodate changes in the radio access network, for example when users move from their offices to their homes.

These multi-technology access solutions are anchored in the Nokia Cloud Packet Core solution. Its native cloud features and operations deliver the performance operators need to provide diverse, demanding and cost-effective applications and services: increased capacity, the large-scale scalability required for network densification, and the deployment flexibility required to deliver low latency.

Nokia continues to help operators plan and optimize their migration to 5G with its 5G Acceleration Services offering and expands its portfolio to include a complete “any haul” transportation offering. Nokia will work with operators to assess the state of their network and design and implement their 5G strategies and services.

We fully understand how changes to individual network elements can affect the network as a whole. And to develop our complete range of products.
