APOD: 2016 January 25 – Where Your Elements Came From

Posted by jpluimers on 2017/07/07

Explanation: The hydrogen in your body, present in every molecule of water, came from the Big Bang. There are no other appreciable sources of hydrogen in the universe. The carbon in your body was made by nuclear fusion in the interior of stars, as was the oxygen. Much of the iron in your body was made during supernovas of stars that occurred long ago and far away. The gold in your jewelry was likely made from neutron stars during collisions that may have been visible as short-duration gamma-ray bursts. Elements like phosphorus and copper are present in our bodies in only small amounts but are essential to the functioning of all known life. The featured periodic table is color coded to indicate humanity‘s best guess as to the nuclear origin of all known elements. The sites of nuclear creation of some elements, such as copper, are not really well known and are continuing topics of observational and computational research.

David Hill – of ThinkPad design fame – is going beyond “Black Paint” – via: Rewiring | Lenovo

Posted by jpluimers on 2017/06/29

David Hill – of ThinkPad design fame – is going beyond “Black Paint”. It means he will be far less involved with [WayBackThinkPad: Industrial design, more with other design and – very important – his loved ones.

[WayBackRewiring | Lenovo:

Today I’m announcing my “rewiring”. I want to broaden my view and create the opportunity to do more in the field of design.

The Cryptowars, twenty years ago – The Isoblog.

Posted by jpluimers on 2017/06/27

Interesting read with lots of references: [WayBackThe Cryptowars, twenty years ago – The Isoblog.

My TL;DR:

  • the current cryptowar is very similar to 20 years ago
  • back then it was won by the people
  • current outcome is unclear (but the rules of math cannot be changed)
  • Laws/Rules/Postulates:
    • John Gilmore
      • »The Net interprets censorship as damage and routes around it.«
    • Shoshana Zuboff
      • »Everything that can be automated will be automated.«
      • »Everything that can be informated will be informated.«
      • »Every digital application that can be used for surveillance and control will be used for surveillance and control.«
  • Kristian:
    • »20 years later, the Cryptowar is still a thing. It will never be over.«
