Session 3 of TED2020, hosted by TED’s head of curation Helen Walters and writer, activist and comedian Baratunde Thurston, was a night of something different — a night of camaraderie, cleverness and, as Baratunde put it, “a night of just some dope content.” Below, a recap of the night’s talks and performances.

In a heartfelt and candid moment to start the session, Tony- and Emmy-winner Cynthia Erivo performs “A Pledge to Rescue Our Youth,” an iconic 2006 poem by Maya Angelou. “You are the best we have. You are all we have. You are what we have become. We pledge you our whole hearts from this day forward,” Angelou writes.

“Drawing has taught me to create my own rules. It has taught me to open my eyes and see not only what is, but what can be. Where there are broken systems … we can create new ones that actually function and benefit all, instead of just a select few,” says Shantell Martin. She speaks at TED2020: Uncharted on June 4, 2020.

Shantell Martin, Artist

Big idea: Drawing is more than just a graphic art — it’s a medium of self-discovery that enables anyone to let their hands spin out freestyle lines independent of rules and preconceptions. If we let our minds follow our hands, we can reach mental spaces where new worlds are tangible and art is the property of all – regardless of ethnicity or class.

How? A half-Nigerian, half-English artist growing up in a council estate in southeast London, Martin has firsthand knowledge of the race and class barriers within England’s institutions. Drawing afforded her a way out, taking her first to Tokyo and then to New York, where her large-scale, freestyle black and white drawings (often created live in front of an audience) taught her the power of lines to build new worlds. By using our hands to draw lines that our hearts can follow, she says, we not only find solace, but also can imagine and build worlds where every voice is valued equally. “Drawing has taught me to create my own rules,” Martin says. “It has taught me to open my eyes and see not only what is, but what can be. Where there are broken systems … we can create new ones that actually function and benefit all, instead of just a select few.”


“If we’re not protecting the arts, we’re not protecting our future, we’re not protecting this world,” says Swizz Beatz. He speaks at TED2020: Uncharted on June 4, 2020. (Photo courtesy of TED)

Big idea: Art is for everyone. Let’s make it that way.

Why? Creativity heals us — and everybody who harbors love for the arts deserves access to them, says Swizz Beatz. Interweaving a history of his path as a creative in the music industry, Beatz recounts his many successful pursuits in the art of giving back. In creating these spaces at the intersection of education, celebration, inclusion and support — such as The Dean Collection, No Commissions, The Dean’s Choice and Verzuz — he plans to outsmart lopsided industries that exploit creatives and give the power of art back to the people. “If we’re not protecting the arts, we’re not protecting our future, we’re not protecting this world,” he says.


“In this confusing world, we need to be the bridge between differences. You interrogate those differences, you hold them for as long as you can until something happens, something reveals itself,” says Jad Abumrad. He speaks at TED2020: Uncharted on June 4, 2020. (Photo courtesy of TED)

Big Idea: Storytellers and journalists are the bridge that spans conflict and difference to reveal a new meaning. 

How: When journalist Jad Abumrad began storytelling in 2002, he crafted each story to culminate the same way: mind-blowing science discoveries, paired with ear-tickling auditory creations, resolved into “moments of wonder.” But after 10 years, he began to wonder himself: Is this the only way to tell a story? Seeking an answer, Abumrad turned to more complex, convoluted stories and used science to sniff out the facts. But these stories often ended without an answer or resolution, instead leading listeners to “moments of struggle,” where truth collided with truth. It wasn’t until Abumrad returned to his home of Tennessee where he met an unlikely teacher in the art of storytelling: Dolly Parton. In listening to the incredible insights she had into her own life, he realized that the best stories can’t be summarized neatly and instead should find revelation — or what he calls “the third.” A term rooted in psychotherapy, the third is the new entity created when two opposing forces meet and reconcile their differences. For Abumrad, Dolly had found resolution in her life, fostered it in her fanbase and showcased it in her music — and revealed to him his new purpose in telling stories. “In this confusing world, we need to be the bridge between differences,” Abumrad says. “You interrogate those differences, you hold them for as long as you can until something happens, something reveals itself.”

Congressman John Lewis, politician and civil rights leader, interviewed by Bryan Stevenson, public interest lawyer and founder of the Equal Justice Initiative — an excerpt from the upcoming TED Legacy Project

Big idea: As a new generation of protesters takes to the streets to fight racial injustice, many have looked to the elders of the Civil Rights Movement — like John Lewis — to study how previous generations have struggled not just to change the world but also to maintain morale in the face of overwhelming opposition.

How? In order to truly effect change and move people into a better world, contemporary protestors must learn tactics that many have forgotten — especially nonviolent engagement and persistence. Fortunately, John Lewis sees an emerging generation of new leaders of conscience, and he urges them to have hope, to be loving and optimistic and, most of all, to keep going tirelessly even in the face of setbacks. As interviewer Bryan Stevenson puts it, “We cannot rest until justice comes.”

Vulkan update: now with added source code

Today we have a guest post from Igalia’s Iago Toral, who has spent the past year working on the Mesa graphic driver stack for Raspberry Pi 4.

It is almost five months since we announced the Vulkan effort for Raspberry Pi 4. It was great to see how many people were excited about this, and today we would like to give you a status update on our progress over these last months.

When we announced the effort back in January we were at the point of rendering a coloured triangle, which required only minimal coverage of the Vulkan 1.0 API in the driver. Today, we are passing over 70,000 tests from the Khronos Conformance Test Suite for Vulkan 1.0 and we have an implementation for a significant subset of the Vulkan 1.0 API.

Progress so far, in pictures

While I could detail here all the features that we have implemented, I am sure that list would get long and boring very quickly for most of you. So, instead, we would like to show you our progress through pics taken from a bunch of the popular Vulkan demos by Sascha Willems running on Raspberry Pi 4:

Hopefully that is more entertaining than a feature checklist and will help you visualize better where we are now compared to January’s coloured triangle.

Before you get too excited though, while these demos are nice, they are still a far cry from actual games and applications. We still have a lot of work to do before the driver can handle these more complex workloads. Even some of Sascha’s demos don’t run yet, whether because of driver bugs or unimplemented Vulkan features. We still have a lot of work ahead of us.

Next up

I would also like to give you an overview of some of the things we will be working on in the coming months:

Our first priority is to support the basic Vulkan 1.0 feature set. This will involve, at least, supporting compute shaders, input attachments, texel buffers, storage images, pipeline caches, and multisampling. There are some other features that we need to support in Vulkan 1.0, such as robust buffer access etc, but those are probably the largest ones we are currently missing.

Once we are feature-complete we will probably move focus to CTS conformance, which will be all about bugfixing, and making sure we handle spec corner cases. And once we are close to conformance, the driver should hopefully be stable and robust enough that we should probably start testing actual Vulkan applications and games to drive further bugfixing work.

Finally, there will be a lot of performance tuning and optimization work that we will probably tackle in the last stages of development.

So as I said before, we still have a long way to go!

Moving development to an open repository

Before we end this post, I would also like to share another important piece of news: starting today, we are moving development of the driver to an open repository. You can find instructions on how to build and install the driver here. I know this is something that many of you have been asking for, and I am sorry that it took us a few months to get here. But I think that now that we have a more stable driver infrastructure in place, and we don’t feel like we are constantly making large changes every other day, development should be a lot friendlier to external contributors than it may have been a few months ago.

So that’s everything we wanted to share today – I hope you are still excited about Vulkan and looking forward to future updates. In the meantime, if you have questions or are interested in contributing to the driver, join us on irc.freenode.net, #videocore channel.

The post Vulkan update: now with added source code appeared first on Raspberry Pi.

As anyone who reads this blog probably knows, I have a bit to do with the operation and maintenance of the Northern Utah WebSDR – a remote receiver system that allows anyone with Internet access and a web browser to listen to the LF, MF, HF and some of the VHF bands as heard from a rural site in Northern Utah. The equipment for this receiver system is located a small building in the middle of mosquito and deer-fly infested range land near brackish marshes – no-where that anyone in their right mind would like to be during most of the year. With the normal hot weather in the summer and many clear days, this building gets hot at times: It’s been observed to exceed 130F (55C) on the hottest days inside – a temperature that causes the fans on the computers scream!
