The Smart Home Gains An Extra Dimension

-

With an ever-growing range of smart-home products available, all with their own hubs, protocols, and APIs, we see a lot of DIY projects (and commercial offerings too) which aim to provide a “single universal interface” to different devices and services. Usually, these projects allow you to control your home using a list of devices, or sometimes a 2D floor plan. [Wassim]’s project aims to take the first steps in providing a 3D interface, by creating an interactive smart-home controller in the browser.

Note: this isn’t just a rendered image of a 3D scene which is static; this is an interactive 3D model which can be orbited and inspected, showing information on lights, heaters, and windows. The project is well documented, and the code can be found on GitHub. The tech works by taking 3D models and animations made in Blender, exporting them using the .glTF format, then visualising them in the browser using three.js. This can then talk to Hue bulbs, power meters, or whatever other devices are required. The technical notes on this project may well be useful for others wanting to use the Blender to three.js/browser workflow, and include a number of interesting demos of isolated small key concepts for the project.

We notice that all the meshes created in Blender are very low-poly; is it possible to easily add subdivision surface modifiers or is it the vertex count deliberately kept low for performance reasons?

This isn’t our first unique home automation interface, we’ve previously written about shAIdes, a pair of AI-enabled glasses that allow you to control your devices just by looking at them. And if you want to roll your own home automation setup, we have plenty of resources. The Hack My House series contains valuable information on using Raspberry Pis in this context, we’ve got information on picking the right sensors, and even enlisting old routers for the cause.

Takeaways from the outcry over Dior’s Johnny Depp perfume ad: Tuesday Wake-Up Call

-
Welcome to Ad Age’s Wake-Up Call, our daily roundup of advertising, marketing, media and digital news. You can sign up to get an audio version of this briefing on your Alexa device. Dior pulls a perfume ad starring Johnny Depp Yet another luxury brand just had to backtrack after a culturally insensitive move. Dior on Friday pulled an ad for its “Sauvage” perfume, as Business of Fashion reports ; the spot starred Johnny Depp playing guitar in the desert while a Native American dancer, Canku One Star, performed in traditional dress. The company portrayed the spot as “an authentic journey deep into the Native American soul.” But the brand was quickly accused of cultural appropriation. Critics seemed most troubled by the juxtaposition of Native American imagery with the word "Sauvage"—which means “wild” in French, but which also evokes the history of labeling indigenous groups as “savages.”  LVMH-owned Parfums Christian Dior had apparently tried to proceed cautiously. It coo

When the coronavirus infodemic strikes

Social media sites are stepping up their efforts in the war against misinformation… specifically, the coronavirus/COVID-19 infodemic . There’s a seemingly endless stream of potentially dangerous misinformation flying around online related to the COVID-19 pandemic, and that could have fatal results. It’s boomtown in fake-news land riding high on the wave of people being left with their tech devices 24/7. I myself regularly see everything posted online from “hand gel is an immunizer” (nope) and “children can’t be affected” (not true) to “UK rules mean domestic abuse survivors have to stay with their abusive spouse” (absolutely not true at all and hugely dangerous to claim).  We even have engineers being spat on thanks to 5G conspiracy theories potentially resulting in transmission of coronavirus . Turns out a global pandemic is a lightning rod for pushing people to conspiracy theories galore, to the extent that some folks have to go hunting for guides to wean their family members a

Patch, Or Your Solid State Drives Roll Over And Die

Expiration dates for computer drives? That’s what a line of HP solid-state drives are facing as the variable for their uptime counter is running out. When it does, the drive “expires” and, well, no more data storage for you! There are a series of stages in the evolution of a software developer as they master their art, and one of those stages comes in understanding that while they may have a handle on the abstracted world presented by their development environment they perhaps haven’t considered the moments in which the real computer that lives behind it intrudes. Think of the first time you saw an SQL injection attack on a website, for example, or the moment you realised that a variable type is linked to the physical constraints of the number of memory locations it has reserved for it. So people who write software surround themselves with an armoury of things they watch out for as they code, and thus endeavour to produce software less likely to break. Firmly in that arena is the size
