Superhero-vision camera

Wednesday, February 14th, 2018

NPR all tech considered: Super Sensitive Sensor Sees What You Can’t.

“A team of engineers at Dartmouth College has invented a semiconductor chip that could someday give the camera in your phone the kind of vision even a superhero would envy. […] Fossum calls his new technology QIS, for Quanta Image Sensor. Instead of pixels, QIS chips have what Fossum and his colleagues call “jots.” Each jot can detect a single particle of light, called a photon.”

Paweł Zadrożniak: Cover of Imperial March by computer hardware orchestra. (YouTube, 1:50min) The sober title doesn’t do the music justice.

Here’s how Paweł Zadrożniak built his “orchestra”: Return of the Floppies. He has videos of dozens and dozens of songs, the most recent is Africa by Toto.

The Guardian: How a new technology is changing the lives of people who cannot speak. “Millions are robbed of the power of speech by illness, injury or lifelong conditions. Can the creation of bespoke digital voices transform their ability to communicate?” By Jordan Kisner.

“Last November, Joe Morris, a 31-year-old film-maker from London, noticed a sore spot on his tongue. […]
The image revealed a tumour like an iceberg. It was rooted deep in the base of Joe’s tongue, mounding upward and out, its tip breaking the surface just where the telltale sore was located. […]

“You’re going to lose two-thirds of your tongue,” the doctor was telling him. “This is going to seriously affect your ability to eat. And your speech.”

Joe wanted to know how the surgery would affect his speaking. Would he have a lisp?

The doctor hesitated, and then looked at his hands. “Your family will still be able to understand you.””

Facebook is cutting out the human element of [tagging the photo]

Wednesday, December 20th, 2017

NPR the two-way: Facebook Expands Use Of Facial Recognition To ID Users In Photos.

“Facebook is expanding its use of facial recognition software to alert users when photos of them are posted on the platform — whether or not they are tagged in the photo.

By default, Facebook users in the U.S. will be signed up for these face recognition alerts, unless they have previously opted out of a similar, more limited feature. But users can turn off face recognition, Facebook says.

Additionally, the company says it will roll out new tools to alert users if someone else may be impersonating them with a misleading profile photo.”

“Das Ausmaß der Datensammlung verstößt gegen zwingende europäische Datenschutzwertungen”

Deutsche Welle: Bundeskartellamt: Facebook missbraucht Nutzer-Daten. “Das Onlinenetzwerk Facebook gerät unter Druck. Das Bundeskartellamt wirft dem Konzern das “missbräuchliche” Sammeln und Verwerten von Daten vor. Damit würde Facebook seine Marktmacht ausnutzen, so die Behörde.”

“Die Wettbewerbsbehörde sehe vor allem die Datensammlung außerhalb des sozialen Netzwerks und ihre Zusammenführung mit dem Facebook-Konto als “problematisch” an, erklärte Kartellamtspräsident Andreas Mundt in einer vorläufigen Einschätzung. Zu diesen Drittseiten gehören dem Kartellamt zufolge einerseits konzerneigene Dienste wie WhatsApp oder Instagram, aber auch Webseiten und Apps anderer Betreiber, auf die Facebook über Schnittstellen zugreifen kann. “Dies geschieht sogar schon, wenn man zum Beispiel einen ‘Gefällt Mir-Button’ gar nicht nutzt, aber eine entsprechende Seite aufgerufen hat, in die ein solcher Button eingebettet ist”, erklärte Mundt. Dies sei den Nutzern nicht bewusst.”
