Practical Color Theory for People Who Code

Posted by jpluimers on 2018/06/18

Recommented reading and playing: [Archive.isPractical Color Theory for People Who Code which is not just about the colour wheel, but also about:

  • desaturation
  • mixing
  • contrast for tints and shades

Oh: don’t forge the “Party Mode” (:

Exclusive: The Silicon Valley quest to preserve Stephen Hawking’s voice – San Francisco Chronicle

Posted by jpluimers on 2018/04/01

Long read: [WayBackExclusive: The Silicon Valley quest to preserve Stephen Hawking’s voice – San Francisco Chronicle

Eric Dorsey, a 62-year-old engineer in Palo Alto, was watching TV Tuesday night when he started getting texts that Stephen Hawking had died. He turned on the news and saw clips of the famed physicist speaking in his iconic android voice – the voice that Dorsey had spent so much time as a young man helping to create, and then, much later, to save from destruction. Dorsey and Hawking had first met nearly 30 years earlier to the day. In March 1988, Hawking was visiting UC Berkeley during a three-week lecture tour. At 46, Hawking was already famous for his discoveries about quantum physics and black holes, but not as famous as he was about to be.

Wolfgang Rupprecht on Dennis H. Klat, Carlos Hawking and Deeklatt – Google+

Posted by jpluimers on 2018/03/18

Wow: [WayBackWolfgang Rupprecht – Google+:

Dennis H. Klatt 1938 – 1988

I knew him at MIT. He was my undergraduate thesis advisor and was a kind and gentle person. When I knew him around 1980 he was about to build the prototype for the first Klatt Talker as it was called then. He had speech samples generated by running his mathematical model of the vocal tract on a large mainframe, but no way to generate speech in real time. I remember being quite happy years later when I heard he had convinced DEC to produce it. The local Boston radio stations would sometimes use it on air when they were goofing around. The initial voice (and the only voice early on) had a bug that made it sound like a Mexican accent to most people. It wasn’t intentional and was a bit of a surprise that a vocal tract modeled from first principles would sound that way. Going with that observation and figuring it was best to advertise bugs as features, the voice was often called “Carlos”. I didn’t realize that Hawking’s voice was also based on the Klatt models (and Klatt’s own voice at that!)

Poking around Google to see what else Google had on him dredged up one more interesting tidbit. There was a character in a TV cartoon called Deeklatt that used his voice. I wonder how many people realize that Deeklatt was a play on D. Klatt. Dennis, we should all be so lucky as to leave a legacy like yours.

[WayBack] Google’s AI can create better machine-learning code than the researchers who made it:

Google’s AutoML project has yielded significant advances in the ability for machine-learning systems to replicate and improve AI code.

On my reading list: Wait by Why on Elon Musk’s latest venture on neural stuff.

#Maths #fun – great graphics help to understand math

Posted by jpluimers on 2016/06/17

Good visualisations make math so much easier to grasp, so I completely agree with Thomas Mueller (dummzeuch)  who wrote “Why didn’t my Maths teachers use this kind of graphic? Why wasn’t it in the expensive book?”

Via #Maths #fun – I’m Programmer – Google+

Actual source: Binomial theorem: Geometric explanation – Wikipedia, the free encyclopedia picture File:Binomial expansion visualisation.svg – Wikipedia, the free encyclopedia (red/purple/blue) and File:Binomial theorem visualisation.svg – Wikimedia Commons (red/orange/green/blue)

I like the last picture best (I wonder though what colour blind people think about them).
