In this video, Dona and Sarah are joined by Sangya Singh, Chief Experience Officer and Director of Product Development at Microsoft.

Sangya has a huge amount of experience in leading product and developing strategy for that product, but she also has an immense amount of empathy for her audiences. In this episode she shares how she uses this empathy together with human centred design to lead how to lead makers AND users of the Power Platform to have the best experiences possible that ultimately changes lives.

Half Ideas – Startups and Entrepreneurship takes a closer look at GPT-3 and what it means for AI.

GPT 3 can write poetry, translate text, chat convincingly, and answer abstract questions. It’s being used to code, design and much more. I’ll give you a demo of some of the latest in this technology and some of how it works.

GPT 3 has been developed for a number of years. One of the early papers published was on Generative Pre-Training. The idea behind generative pre-training (GPT) is that while most AI’s are trained on labeled data, there’s a ton of data that isn’t labeled. If you can evaluate the words and use them to train and tune the AI it can start to create predictions of future text on the unlabeled data. You repeat the process until predictions start to converge.   

The 3D Handyman shares an interesting technique to address the mask shortage in light of the COVID pandemic.

However, there are safety concerns you should take seriously. Highlights added.

I’m sharing this video here to inspire folks to use the tools and expertise at their disposal to fight this awful disease.

Your safety is no joke! Read all this information!

WARNING! The activated carbon layer of the MERV 16 filter used in this video appears to contain fiberglass!

Other home air filters may also contain Fiberglass! Do not use fiberglass based materials for breathing devices! One possible test is if you can melt the filter material into a plastic blob with a standard lighter it is likely a synthetic material. If the material can not be melted, there is a high likelihood that it is fiberglass. That said, it can be very difficult to determine what these filters are made of and some may be a small percentage fiberglass. Use extreme caution when making any type of breathing device! Emailing the manufacturer may be the only way to find out what the filter is made out of.

There are lots of materials that can be loaded into this and other 3D printed mask designs. According to “tests at Missouri University and University of Virginia, scientists found that vacuum bags removed between 60 percent and 87 percent of particles.” This article also mentions “A 600 thread count pillow case captured just 22 percent of particles when doubled, but four layers captured nearly 60 percent.” This may indicate that a double layer of a MERV 12 filter (or lesser rated filters) may have much better filtration performance than just a single layer. ALSO “The problem with air filters is that they potentially could shed small fibers that would be risky to inhale. So if you want to use a filter, you need to sandwich the filter between two layers of cotton fabric.” Good advice! https://www.nytimes.com/2020/04/05/well/live/coronavirus-homemade-mask-material-DIY-face-mask-ppe.html

It appears many 3D printed masks do not have enough filter surface area and negate the manufacturer filtration ratings and can actually lead to CO2 build up in the mask cavity and in your body. This particular design appears to have enough surface area to function without these issues. However, keep this in mind and if you choose to wear a device like this

REMOVE IT if you feel light headed, dizzy, headache, confusion, etc. (Carbon Dioxide Poisoning) and NEVER wear a mask while sleeping.

Jamie Paik explores more creative forms of robots.

From the video description:

Taking design cues from origami, robotician Jamie Paik and her team created “robogamis”: folding robots made out super-thin materials that can reshape and transform themselves. In this talk and tech demo, Paik shows how robogamis could adapt to achieve a variety of tasks on earth (or in space) and demonstrates how they roll, jump, catapult like a slingshot and even pulse like a beating heart.
