How much DNA do we share?

I was chatting with "likely" relative, geneticist, on my father's side.

- humans and chimps share 97-99%,
- humans, like myself, and Neanderthals share 3%,
- 3rd to 4th cousins share 0.8%, 

Should this explain why I feel more at home in the ZOO then over the birthday party of my grand-aunt? 

Written of course as a joke, still, it needs clarification. I hope to see an article soon.

Japanese wood plane (kana)

This is my first time using the Japanese wood plane (kana). 

After sharpening and setting it up, I was able to take the single-cell shavings and glass-finish the wood with no need for the sanding paper.

Ubuntu build C++ project ND313

Install C++ Compiler on Ubuntu (command line)

-- The CXX compiler identification is unknown
No CMAKE_CXX_COMPILER could be found.

$ sudo apt-get update && sudo apt-get install build-essentialOR$ sudo apt install cmake

Install Point Cloud Library (PCL)

The Point Cloud Library (or PCL) is a large scale, open project for point cloud processing.

The PCL framework contains numerous state-of-the art algorithms including filtering, feature estimation, surface reconstruction, registration, model fitting and segmentation.

PCL is released under the terms of the BSD license and is open-source software. It is free for commercial and research use. We are financially supported by Willow Garage, NVidia, and Google.

Point Cloud Library (PCL) on Mac OS

Install PCL using BREW.

PCL is a Point Cloud Library for C++

$ xcode-select --install

xcode-select: error: command line tools are already installed, use "Software Update" to install updates



After updating Mac OS, please re-install the brew:

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

$ brew update

Already up-to-date.

$ brew tap homebrew/science
Error: homebrew/science was deprecated. This tap is now empty as all its formulae were migrated.

$ brew tap brewsci/science

DANGER (no need to do it if you re-insalled the brew):

$ sudo install -d -o $(whoami) -g admin /usr/local/Frameworks

$ brew reinstall pcl
