YouTube Introduces Streaming Of HDR Videos 1
YouTube, the second most popular website on the internet, has added the ability to effect change and the adoption of new technologies in visual mediums like no other website. In the past it’s used that ability to good use. It was an early adopter of 4K content and continues to possess the largest repository of said content. The same is true of 360 video. Now YouTube is finally embracing HDR, which means newer videos are going to look a lot more realistic .

HDR, or high dynamic range, is the latest buzz word for video and televisions. It’s a process that gives videos substantially more details in areas of extreme brightness or shadows. This allows the video to look more like how you perceive the real world versus how the lens of a camera sees it.

This is an example of HDR from the game Infamous First Light. As this is a JPEG viewed on a non-HDR monitor it will appear different from the real thing.

Starting today anyone can upload a video with HDR to YouTube, however playing it will be much more complicated. You’re first going to need a display that can handle HDR. Currently, HDR requires displays that push out well over 1000 nits of brightness-the best mobile devices only manage around 500-600 nits. Which means you can’t enjoy HDR video on your smartphone, laptop, or tablet. Instead, you’re going to have to watch it on your TV, which will need to have HDR capabilities.

Samsung UHD and SUHD TVs from 2016 will get the ability to play HDR YouTube videos later this year. The new Chromecast Ultra, which was made available on the Google Store starting yesterday, is the only confirmed set-top box that can playback YouTube videos with HDR. Yet expect Roku and Amazon to follow suit eventually. Apple, meanwhile, still hasn’t even embraced 4K video-so an Apple TV app that can playback HDR video is extremely unlikely any time soon.

This is the Photographer behind the viral Image that crashes your Android  Smartphones 4

We announced Sony’s reveal of the PlayStation 5 last week but seems some individuals will be have a budget rethink all the same after a reported Image shared on Flickr crashed hundreds of Android smartphones.

San Diego-based scientist Gaurav Agrawal has emerged as the photographer behind the controversial image that caught headlines for crashing many Android phones recently.

Just like many freelance photographer would do, Agrawal took that image at Saint Mary Lake in Glacier National Park, Montana, back in August last year of a sunset landscape which he later uploaded on Flickr without knowing the fact that it would become viral — for just about all the wrong reason.

Who is Gaurav Agrawal

Indian-origin photographer. He started his journey with landscape photography as a hobbyist — perhaps by hijacking what was initially the interest of his wife.

He got his first camera phone as the instrument to capture scenes in his frames back in 2006. But that was just a beginning.

Afterwards, he got his Ph.D. from the Indian Institute of Science in Bengaluru, has been selected as a part of National Geographic photo assignments. He said that one of the photographs he took at the Salton Sea of the Great White American Pelicans was even selected as the cover page of the yearly calendar of the Audubon Society of North America.

Furthermore, he has won various photo competitions earlier, including one at the University of California, San Diego, where he did his post-doctoral work.

But then, his smartphone crashing image might just have skyrocketed his popularity in the tech world with renowned YouTubers and major tech sites all detailing on his beautiful and awesome-esque image.

What image did Agrawal upload to Flickr?

Just as we stated above, the image was of a Lake in Glacier National Park, Montana captured using a Nikon DSLR and uploaded on Agrawal’s Flickr profile on September 16, 2019.

However, before sharing publicly, he explained on Flickr that he used the image editing tool Adobe Lightroom through which he changed the format to ProPhotoRGB.

Before you get super confused on what ProPhotoRGB Image formatting is and probably asking yourself

According to PetaPixel, ProPhotoRGB is a newer color space and default work extension for Adobe Lightroom edits that has a much wider gamut than normal sRGB and is
more in line with modern digital cameras.

Smartphones won’t even be able to decode and display the colours…

However, sRGB has a relatively narrow gamut but is designed for consistency and compatibility for all photos shared on the Web.

This ProPhotoRGB image extension isn’t supported by some Android devices and, thus, resulted in issues with several phones.

What has Agrawal said about the recent developments to his photograph?

No doubt, the crashes with that single photo have ultimately made Agrawal to switch to another format from now on but he had a lot to say to the public on his controversial image.

However, people weren’t even aware that the image was captured by Agrawal until he gave an interview to BBC earlier last week.

He told Indian news site, Gadgets 360, that the original source of the image wasn’t public as it was mainly shared by a third-party wallpaper site that didn’t credit him and was circulating the image without any due credits.

Agrawal told Indian news site Gadgets 360 that he got to know about the crashes users faced from his image from some of his followers on Flickr.

After receiving comments and messages on the platform, he searched the term “Android crashing wallpaper” on
Google to understand the issue.

“I would have been very disappointed if something like that would happen to me,” he said. “There were some websites touting conspiracy theories that it may be a targeted attack by China or Russia.

In the midst of a trade row between the United States and the Chinese, this made it even more unsettling.

“It was alarming to say the least,” Agrawal, 41, told Gadgets 360 in a conversation. “I felt sympathetic to people who may have lost their data and photographs due to the crash.”

Bottom Line

The crashes with that single photo have ultimately made Agrawal to switch to another format from now on.

Furthermore, he’s planning to expand his photography reach by joining Instagram — alongside maintaining his Flickr profile that has over 10,600 followers.
“I deeply care about my viewers and look forward to their appreciation as well as constructive criticism,” he said.

Though iOS devices were not affected, they always seem to have their way

The accidental Android crashing wallpaper issue could have escalated quickly had conspiracy theorist been allowed to have their way.

However, if you find yourself amongst the crew that went ahead to check out the photo on your smartphones, you now have a new tech budget to handle.

Covid-19 Cyber attacks Spike as Health sectors battle Hackers: Here's how to stay safe 7

The world continues to battle the deadly Covid-19 pandemic also called Coronavirus as many sectors and companies encourage their staffs to work from home.

Office workers who usually don’t have much time for their social networks and mass random messages now have ample time to go through their devices and computers and even see a few movie series.

Coronavirus regulation in Nigeria

Ironically, this is possible as individuals cling to the only thing that could help them communicate with the outer work – their smartphones.

This large number of human force all stuck at home has led a major increase in online scammers as even the ethical one’s amongst them have grown bored and looking for new loopholes to exploit.

Organizations are been targeted, individuals are made to pay the price for being idle, phishing mails are getting sent and received at a rate of a thousand mails every second. But asides all these, individuals are encouraged to stay safe from the deadly virus with recorded infection figures going up each day here in the part of the world.

Seems everyone forgot about the other safe which is very much vital too??!

Covid-19 fraud related cases

The U.S. Federal Bureau of Investigations (FBI) is warning the Internet community that COVID-19 has sparked rising scammers leveraging the deadly virus to steal money, personal information or both from users of online services.

“Protect yourself and do your research before clicking on links purporting to provide information on the virus; donating to a charity online or through social media; contributing to a crowdfunding campaign; purchasing products online; or giving up your personal information in order to receive money or other benefits”, the US law enforcement agency advises.

In this part of the world where vulnerable individuals hardly struggle to survive each day, talks making rounds on the internet regarding the Nigerian government sharing stimulus package of N20,000 to every citizen has done little to help arrest the issue of cybercrime.

Covid-19 Cyber attacks phishing emails

Hackers and scammers have been continuously bombarding individuals with phishing links to give away their details so as to enlist them and reserve their own package; which invariably is only sugar-coated lies.

This is not a happy sight as so many individuals who struggle to make through each day with their families end up giving away the little they have in reserve.

A recent war brewing between the United States and China over alleged hack into the former’s Covid-19 vaccine research systems just goes about to tell you no one is exempt from the monster that is Cyber attack.

Furthermore, company’s have had to educate their staffs with regards to working from home and handling logins both on personal and public computers as any major breakthrough in user data could finally result in giving away company information which isin’t really a worthy report.

FBI says Internet users should always use good cyber hygiene and security measures when they are online.

According to the law enforcement agency, the following five(core) tips are vital for any Internet user to protect themselves and help limit the rate of cybercrime activity:

  1. Do not open attachments or click links within emails from senders you don’t recognize no matter how tempting the message contained is.
  2. Do not provide your username, password, date of birth, social security number, BVN, financial data, or other personal information in response to an email or robocall from a random individual.
  3. Always verify the web address of legitimate websites and manually type them into your browser. If possible Google search the address name categorically before clicking through.
  4. Check for misspellings or wrong domains within a link (for example, an address that should end in a “.gov” ends in .com” instead).
  5. If you believe you are the victim of an Internet scam or cyber crime, or if you want to report suspicious activity, don’t hesitate to contact the institution involved ASAP.

Internet fraud is a monster that won’t just go away yet but with staying safe, careful and regulating our online footprints, we could save lives and cooperations at large.
