Facebook also said in June that it had developed AI software to not only identify deepfake media, but also to understand where they came from.

In July, AI Singapore launched a five-month competition to design solutions that will help detect fake media, with entrants having access to datasets of original and fake multimedia videos with audio.

Entrants will need to create AI models that estimate the likelihood of a given video being fake, with the winner – expected to be announced in January of next year – earning S $ 100,000 and a seed grant of $ 300,000. S to further develop their solutions. using Singapore as a base.

Beyond the use of AI, Assoc Prof Li said deepfake technologists should also work closely with regulators. “You want to impose laws that essentially prevent illegal use of this type of technology,” he added.

PASSAGE TO THE GENERAL PUBLIC

However, Assoc Prof Li pointed out that deepfakes can be used in a positive way, for example to improve visual effects, including aging in videos. He is currently working with high-end production studios on films using 4K AI synthesis effects, primarily focused on faces.

“One of the technologies we’re developing here in Pinscreen is basically augmenting traditional computer graphics with high-fidelity neural rendering that can run in real-time, so we’ve improved virtual avatars for various applications,” a- he declared.

“It can be used for games, it can be used for creating virtual assistants, but also for very realistic telepresence applications where people can immerse themselves in virtual worlds.”

Assoc Prof Li predicted that deepfake technology will eventually become mainstream, given that people already live in a digital society with various social media tools to change their appearance.

“Once these things look better, people will start to use these technologies differently and go beyond what’s possible,” he said.

“So maybe you don’t even want to be yourself, you want to be someone else. That, I think, will definitely be an ability that will be available.”

YouTube is the most popular video sharing and social media platform launched in 2005 and now owned by Google.

It is one of the busiest media platforms with over a billion monthly users. Users of this platform also consume over a billion hours of content per day.

Anyone can become a creator on YouTube and upload videos according to their guidelines. With such a large user base, YouTube is also opening itself up to activities such as spam which ruins the overall experience.

According to reports (1, 2, 3, 4, 5, 6), many users are concerned about the increasing number of adult comments on Xvideos Red posted by sex robots. Users complain that NSFW bot profiles show up all over the place in responses.

They are not people, they are real bots, they use AI. They copy comments from similar comments and videos and paste them below your comment. (Source)

These are on all of my comments now. They copy the most popular comments on the video and paste them as comments on the comments. The spam message is in the username. Presumably, the spam detection system primarily cares about the content of the comment.

I was flagging them as sexually explicit then, but YouTube probably needs to learn how to automatically detect them to have an impact. (Source)

These bots show up with NSFW names and profile pictures that aren’t suitable for kids and it can give off a bad impression. However, comments made using these profiles are not NSFW but simply spam.

In fact, these bots use AI and copy comments from similar videos and paste them under user comments as a response. This activity is now increasing day by day and must seriously decrease.

The profile picture used by these bots is considered pornographic content which should not appear as many users on YouTube are under the age of 18.

Due to the vast content and users, YouTube has automated a lot of things like copyright and automatic removal of channels with inappropriate content, yet bots are free to comment anywhere.

Meanwhile, YouTube hasn’t said anything about it as to why this is happening and when it will be fixed.

These spam activities should not be happening on such a large platform and this is something that needs to be fixed as soon as possible.

While waiting for YouTube’s response on this, you can share your thoughts on this whole situation in the comments below. In addition, we will keep you posted on the development of this story.

Jimmy Fallon and Stephen Colbert both skewered OnlyFans’ decision to ban pornographic videos, a move that was announced Thursday.

The content subscription service said that starting in October, it will no longer allow “sexually explicit behavior” on the platform, a decision made at the request of banking partners and payment providers.

OnlyFans, founded in 2016, is best known for presenting adult content and has been hailed as a safe space for sex workers.

“Obviously, pornography doesn’t live up to the high moral standards of investment bankers – unless they’re the ones screwing the economy,” Colbert joked. “But I have good news for OnlyFans fans. There is another place to find sexually explicit material on the Internet – it’s called the Internet.

A shocked Fallon also briefly mocked the OnlyFans movement in his Tonight show monologue.

“It would be like Playboy printing only the articles, ”Fallon said. “What if you watch this with someone who quickly asked, ‘What’s OnlyFans? Believe me, they know exactly what it is.

Thematically, White Girl is exactly what it says on the tin, it’s about race and gender. It’s an attempt to portray the main character’s naivety and his ability to get away with his privilege unscathed. An idea with which, if it wasn’t already obvious enough, Elizabeth Wood knocks us out in the scene where Leah is having dinner with the lawyer.

White Girl is unabashedly feminist, and being led by a woman that includes a lot, Leah is not a trope, she is not a stereotype, she is a naive young girl who makes a lot of decisions really, really terrible. But while that’s the basis of her character, the protagonist, as well as the rest of the people in this movie, are only explored on a superficial level. This means that it is difficult to care about what they are doing or what is happening to them. Especially Leah, who knows that as a pretty white girl there are a lot of things she can get away with and get away with unscathed. And we know it too.

Not only is White Girl difficult to hook due to his lack of a real sense of consequence, but he also seems to push us back with his botched attempt at shock cinema. In all the other scenes, someone is sniffing coke, sticking out their breasts, or throwing up their guts (is there anyone in this movie who doesn’t use drugs?). Some of the comments on sexuality, especially female sexuality, are interesting, and there is clearly a lot to be said here about the male gaze and the danger of it towards young women, but then the sex scenes. free never stop to try to shock us, and we lose interest.

A lot of the characters are stereotypes, and the writing for male drug dealers seems to have been written by my dad, guessing how he thinks a drug dealer probably talks. Attempts to make love interest more of a love interest and less of a sexual interest were sometimes hilarious, this movie just couldn’t get the right dialogue for these characters at all, it was goofy as hell.

White Girl was summed up for me when Doug from The Hangover sniffed cocaine on his cock.

When polar bears encounter burgomaster gulls on the remains of a bowhead whale, they may share more than just a meal. As global warming brings animals together, parasites, viruses and bacteria may find opportunities to spread to new and naive hosts, sometimes moving from birds to mammals and from marine ecosystems to terrestrial ecosystems. Credit, USGS.

When wild birds make up a large portion of your diet, opening a freshly downed bird to find worms wriggling under the skin is a bewildering sight. This is exactly what Victoria Kotongan saw in October 2012, when she started cleaning two of the four spruce grouse (Falcipennis canadensis) that she had brought near her home in Unalakleet, on the northwest coast of Alaska. The next day, she shot down four grouse and all four sheltered the long grubs. In two birds, the worms appeared to come out of the meat.

Kotongan, worried about the grouse’s health and the potential risk to her community, reported parasites to the Local Environmental Observer Network, which arranged for the frozen bird carcasses to be sent to a laboratory for analysis. Laboratory results identified worms as the nematode Splendidofilaria pectoralis, a finely described parasite previously observed in the black grouse (Dendragapus obscurus pallidus) in the interior of British Columbia, Canada. The nematode had not been seen so far north and west before. Although S. pectoral is unlikely to be harmful to humans, other emerging diseases in northern regions are not so harmless.

Splendidofilaria pectoralis nematodes wriggle on the meat of a spruce grouse (Falcipennis canadensis).  One weekend in October 2012, Victoria Kotongan killed six spruce grouse near her home in Unalakleet, on Alaska's remote northwest coast.  Four harbored worms visible under their skin.  Filaroid nematodes have never been reported in the Alaskan Grouse before.  Credit, Victoria Kotongan, Local Environmental Observers Network, Alaska Native Tribal Health Consortium.

Animals are altering their seasonal movements and feeding habits to cope with climate change, bringing together species that were rarely seen in the past. Nowhere is this more apparent than in polar latitudes, where the warming has been fastest and most dramatic. Red foxes spread north into arctic fox territory. Hunger drives polar bears to land as sea ice shrinks. Many Arctic birds undertake long migratory journeys and have the mobility to fly well beyond their historic ranges or extend their stay at attractive feeding or nesting sites.

With close contact, there is a risk of infection by parasites and exotic microorganisms carried by new neighbors, and therefore the disease also finds new territory. Clement conditions prolong the life cycle of disease-carrying insects and pathogenic organisms. Migratory birds can carry infectious agents for long distance walks. In November 2013, Native Alaskan residents of St.Lawrence Island, in the Bering Sea, alerted wildlife managers to the deaths of hundreds of Crested Staries, Thick-billed Murres, Northern Fulmar and other seabirds, caused by a epidemic highly contagious avian cholera (Pasteurella multocida).

“This is the first time that avian cholera has appeared in Alaska,” said Caroline Van Hemert, wildlife biologist at the US Geological Survey in Anchorage, Alaska. “St. Lawrence Island is generally frozen over in November, but last year we had a warm fall and winter in Alaska. We don’t know for sure that open water, climate, and high bird densities contributed to the outbreak, but it coincided with unusual environmental conditions.

NDA government saved and bolstered economy left in shambles by UPA, Union minister said at Hindustan Times 2018 Leadership Summit

Railways Minister Piyush Goyal on Friday credited the NDA government with saving and strengthening an economy he said was in shambles when he took office, and empowering citizens by providing them with new Xvideos Red platforms for innovation and entrepreneurship.

“We have by no means lost the narrative on the economy,” said the minister, who was in charge of the finance portfolio during the months Arun Jaitley was recovering from surgery earlier this year, in response to a question posed to the 16th Hindustan Times. Summit of leaders.

The management of the economy by the BJP-led NDA government has been called into question by opposition members amid a weakening rupee, high fuel prices, the build-up of bad debts in the banking system and agrarian distress caused by falling commodity prices. To ease consumer pain on Thursday, the government slashed gasoline and diesel prices by about 2.5 per liter and urged state governments to follow suit.

Goyal said he was confident the BJP would return to power in the 2019 general election with more than 300 seats (he won 282 in 2014) and that the NDA would win a two-thirds majority in Lok Sabha. “We believe in action and people know we have accomplished a lot in the past four years,” he said.

On Indian Railway, the minister described infrastructure improvements made by the NDA government and shared data on changes to the world’s second-largest rail network.

“In 2013-14, 118 accidents were caused at an unmanned crossing, which has dropped to three in the past six months. Almost 5,000 of the 5,500 unmanned crossings have been removed and the rest will be completed by the end of this year, ”he said.

He also spoke of efforts to improve toilets in railways, increase the capacity to introduce new and modern rail cars and rail restoration.

Statistical evidence suggests that cheating is nowhere near as prevalent among ordinary men as it appears to be among pols and jocks and high octane comedians and costumes and other Xvideos Red libidinous creatures. According to the General Social Survey conducted by the National Opinion Research Center at the University of Chicago, no more than 22% of men have ever engaged in marital infidelity, and only one in 20 men unfaithful to his wife each year. .

So if a guy calls his wife to tell her he’s working late, there’s a 95% chance he’s chained to his desk and not dating the new marriageable recruit in Creative Services. (Men are more likely to go astray than women – or at least more likely to admit it – although the gender gap may be narrowing, the survey found: Almost 15% of women say they have cheated.)

Our natural instinct is to believe that loyal men adore their wives, are blissfully happy in their relationships, and would never dream of having fun, as it would violate their personal moral code. You can build entire societies around lies like this. These men are ready to work for succeed in a marriage. For them, marriage is not a trifle, not a lark. Following this logic, men who do not cheat are first class human beings.

But are they? All? Truly?

Over the years, I have met a few guys who cheat on their wives and quite a few who don’t. Or let’s just say I think not. But is it possible that these husbands refrain from cheating not so much because they love their wives, and not even because they regard cheating as immoral, but for other, less laudable reasons? Consider, if only for the sake of argument, the following explanations of why some men are loyal to their wives:

A lot of men are incredibly lazy

Men like to slouch on the couch, watch sports and drink beer. Romance, on the other hand, takes a lot of work; take a shower, shave, put on deodorant, put on something other than sweatpants, buy flowers, go to the movies, read a book every now and then, think of compliments, strike up a conversation. Cheating on your wife involves travel, dinner reservations, hotel room reservations. Once a man has been married a few decades, the energy he would need to devote to an extramarital affair could come as a fatal shock to his nervous system. It would be like asking the Sahara to suddenly burst foliage. That’s why so many older men wouldn’t even think about cheating on their wives. It’s too exhausting.

The Southwire Forged Wire Stripper is feature rich and rugged with heavy duty forged steel. If you’ve already read our review of Southwire stripper Romex, you’re going to see a lot of similarities and that’s a good thing.

ADVANTAGES

  • Durable forged steel construction
  • Wide jaw has aggressive knurling for secure grip and twist
  • Scalloped cutting knives hold line and cable better for cutting
  • 8-16 AWG solid and 10-18 AWG stranded bands
  • Wire loop hole
  • Ergonomic curved handle and comfortable rubber grips
  • Excellent value at $ 26

THE INCONVENIENTS

  • Some pros may prefer longer jaws

Recommendation

The Southwire Forged Wire Stripper takes the standard functions of a wire stripper and puts them in a much more durable and ergonomic construction with a price tag well below what Klein offers. The only thing you need to watch out for is jaw length – some pros may prefer the longer ones.

Southwire Forged Wire Stripper

Materials

If you’ve read our recent review of the Romex Forged Wire Stripper from Southwire, you’ll notice that the Southwire Forged Wire Stripper is very similar. The biggest difference is the shorter jaws of this version.

Southwire Forged Wire Strippers

The main feature of this tool is the sturdy forged steel body. The grips are covered with a rubber grip and they have an ergonomic grip to better fit your hand than straight symmetrical grips.

Southwire Forged Wire Strippers

Operations

The Southwire Forged Wire Stripper strips and loops 8-16 AWG and 10-18 AWG stranded copper wire. The large, aggressively knurled jaws on Xvideos Red"}” data-sheets-userformat=”{"2":513,"3":{"1":0},"12":0}”>Xvideos Red are designed to twist multiple threads simultaneously. The knurling isn’t the heaviest I’ve ever seen, but it’s still aggressive and grips really well for pulling and twisting.

Southwire Forged Wire Strippers

I prefer the longer jaws of the Romex Stripper that I mentioned above, but the shorter jaws of the S816SOLHD still work quite well.

The standard 6-32 and 8-32 screw shears are located in their usual place around the rivet.

Southwire Forged Wire Strippers

Interesting scalloped cutting jaws replace traditional straight knives. This design holds the wire and small cable together so they won’t slip off while you cut them.

Southwire Forged Wire Strippers

The benefits seem to be divided over the spring loaded locking handles. Some find it annoying that the default spring-open position has to lock to keep the jaws closed during storage (do they make it for teenagers?). Others like the convenience of automatic opening during use. You will have to decide on that one.

Southwire Forged Wire Strippers

Considering the weight of the forged steel of the wire stripper, tether loops are a must when working at heights. Southwire will place one at the end of each handle and you can decide if one works better for you than the other.

Price

You can pick up the Southwire Forged Wire Stripper for $ 26 and comes with a lifetime warranty. The closest Klein equivalent, the K12054, is a little more at $ 38. Of course, stamped steel wire strippers are much less numerous and last less.

Southwire Forged Wire Strippers

The bottom line

The Southwire Forged Wire Stripper takes the standard functions of a wire stripper and puts them in a much more durable and ergonomic construction with a price tag well below what Klein offers. The only thing you need to watch out for is jaw length – some pros may prefer the longer ones.

Landing in Barcelona on Saturday afternoon it was hot, sunny and so Spanish. I was greeted at my hotel with a glass of cava to sip and was treated to a tour of the historic hotel. A short rest, a walk around Barcelona and a little work filled the time until dinner – at 8 p.m.

Tuesday morning, the PRACEdays 2017 kicked off as part of the European summit week. The program started with a welcome from Sergi Girona, EXDCI coordinator, and Serge Bogaerts, managing director of PRACTICE, describing the week of plenaries, keynotes, breakout sessions, BoFs and poster sessions. There will be a lot to see and learn this week in Barcelona!

President of the Board of PRACE, Anwar Osseyran was next with a detailed overview of PRACE’s achievements and the challenges ahead. PRACE is proud to provide open access to the best HPC systems for European scientists. Their criterion: scientific excellence.

Anwar Osseyran at PRACEdays 2017

In PRACE partnerships, there are seven “Tier 0” systems (the best systems available for international use), including the recent addition Piz Daint, currently number eight on the Top500 list. Of the seven world-class systems they have, there are over 60 peak performance petaflops supporting 524 science projects.

Anwar categorized the challenges PRACE sees in adapting and modernizing the HPC infrastructure into four quadrants:

  • European open science cloud: allowing permanent access to data. This is a huge challenge for health care.
  • Strong HPC infrastructures for data processing.
  • Adapt HPC solutions to cloud environments to make them easy and accessible to scientists.
  • How to reach the exascale.

As PRACE considers these challenges, the question of funding arises. How will PRACE finance all their ambitions? If they can’t do it all, what technologies and applications should they focus on? As Anwar says, consider “worldly science against heavenly science.” It’s a question of choice.

On more than one occasion during his presentation, Anwar discussed the concept of collaboration between communities versus the advantages of competition. Anwar suggested that competition between scientists produces better results. I would have thought that collaboration between supercomputing centers would be more of a norm – sharing of resources, of results – all contributing to better science.

As Anwar said in his closing statement, “It’s about balancing Xvideos Red"}” data-sheets-userformat=”{"2":513,"3":{"1":0},"12":0}”>Xvideos Red traditional, disruptive and basic science.

The first speech was given by Minna Palmroth, titled Understanding near-Earth space in six dimensions.

Minna Palmroth at PRACEdays 2017

What I really love about events like this is the opportunity to learn about science, big science issues, and things I never thought about. Minna hit the nail on the head in her presentation on near space issues.

The Earth has radiation belts. Navigation and meteorological satellites navigate the plasma around the Earth, passing through radiation belts. Two types of phenomena affect spacecraft and satellites: a single event (such as a system failure) and the aging of the spacecraft due to the strong radiation they experience in the radiation belts.

The radiation belt situation is already extremely important, but will be even more so in the future as the number of spacecraft increases. The challenge in a nutshell: How to simulate a large and ever-increasing number of spacecraft in the radiation belt requires a dense grid and complex grid calculations in multiple dimensions simultaneously.

Minna is a research professor and head of unit in the physics department at the University of Helsinki, Finland. They solve parallelization at three levels:

  • On nodes of clusters and supercomputers using MPI.
  • On multiple cores within a node using OpenMP.
  • In hearts with vectorization.

Their most recent development supports multiple ions, an optimized implementation of boundary conditions resulting in improved scaling. This gave them the processing power and speed to do the calculations necessary for the near-space problems they identified.

The simulations Minna shared of solar winds and radiation belts as they hit Earth’s atmosphere are fascinating. Solar winds create significant amounts of heat which dissipate and propagate through the Earth’s atmosphere.

The system Vlasiator is a new model of large-scale space physics. The goal is to model all of near-Earth space, going well beyond existing large-scale plasma simulations. This will bring the modeling of current solar winds and radiation belts to the optimization of space weather instruments and spacecraft. Vlasiator has been used to discover phenomena that no one thought existed, and with continuous improvements in modeling such as the addition of machine learning, Vlasiator will be an important tool in understanding space phenomena and methods for protecting craft. space, technological systems or human life in space.

The second speech, Using Big Data methodologies in the chemical industry, was donated by Telli van der Lei.

The information shared by Telli is not surprising; We have long known that modeling supply chains can produce positive results. Either way, this is a topic that cannot be discussed enough, especially in a conference with a strong focus on research and teaching (around 73% of attendees). Talking about the commercial application of the science they are modeling and the improvements it enables is a good thing. It takes science and calculation that was developed in one place, used and improved in another, and demonstrated again in the first place.

Telli is an academic, now working for industry. She works for DSM as a senior scientist in supply chain and process modeling. Modeling in the industry, Telli professes, can be quite difficult. In her presentation, Telli talks about the industry issues DSM is thinking about, the results they have achieved with their supply chain modeling, and the challenges they envision for the future.

For industry issues, health is number one. I would say that almost every country in the world faces issues of aging populations, health care, and optimal food composition. After health, nutrition, how to feed the growing population and the surge of urbanization creating clusters of humans while reducing agricultural space is a growing problem. Finally, the resource constraints of the materials available to feed the supply chain are a major problem.

DSM uses computer modeling to simulate the supply chain from raw materials to manufacturing, from warehouse to customer. By using modeling and integrating the process into their supply chain, they have achieved amazing results in terms of order accuracy, supply chain cost reduction, inventory reduction and chain more efficient, flexible and responsive supply chain.

From all of this, they have advanced modeling and analytics that flow from their proven successes. They still see challenges like, from a modeling perspective, how to optimize the input, output and runtime of existing models or incorporate business choices into models? They can use HPC to simulate, but how do you know your results are valuable? As Telli said: “It’s not yay – here we go [with our results], this is how you change your business.
