The new Mac Pro: The audacity to say “Yes” in a design culture of “No”
Much of modern Apple’s design philosophy is to relentlessly strip down most products to the bare minimum in certain areas as technological progress allows, following (and largely defining) the modern design fashion of nearly-unquestioned devotion to minimalism.

Engineers Investigate a Simple, No-Bake Recipe to Make Bricks from Martian Soil
Explorers planning to settle on Mars might be able to turn the planet’s red soil into bricks without needing to use an oven or additional ingredients. Instead, they would just need to apply pressure to compact the soil—the equivalent of a blow from a hammer. These are the findings of a study published in Nature…

GPU Performance for Game Artists
Performance is everybody’s responsibility, no matter what your role. When it comes to the GPU, 3D programmers have a lot of control over performance; we can optimize shaders, trade image quality for performance, use smarter rendering techniques… we have plenty of tricks up our sleeves. But there’s one thing we don’t…

Pruning spaces from strings quickly on ARM processors
Suppose that I give you a relatively long string and you want to remove all spaces from it. In ASCII, we can define spaces as the space character (' '), and the line ending characters ('\r' and '\n'). I am mostly interested in algorithmic and performance issues, so we can simplify the problem by removing all ……

Intel's Management Engine
Recent CPUs from Intel requires a binary called the “Management Engine” (Intel ME, or ME for short). This binary is one of three parts required if a business elects to use Intel’s Active Management Technology (AMT), which Purism avoids. Purism laptops can function with a neutralized and disabled ME, as we have tested…
