Installing Node.js with nvm to Linux & macOS & WSL

A quick guide on how to setup Node.js development environment.

Install nvm for managing Node.js versions

nvm allows installing several versions of Node.js to the same system. Sometimes applications require a certain versions of Node.js to work. Having the flexibility of using specific versions can help.

1. Open new Terminal window.

How to make a debian from a ROS package

The instructions are based on this answers.ros.org thread.

Get dependencies

You may need the latest pip, follow the official instructions.

Install bloom:

This was tested on a ThinkPad P70 laptop with an Intel integrated graphics and an NVIDIA GPU:

lspci | egrep 'VGA|3D'
00:02.0 VGA compatible controller: Intel Corporation Device 191b (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation GM204GLM [Quadro M3000M] (rev a1)

A reason to use the integrated graphics for display is if installing the NVIDIA drivers causes the display to stop working properly. In my case, Ubuntu would get stuck in a login loop after installing the NVIDIA drivers. This happened regardless if I installed the drivers from the "Additional Drivers" tab in "System Settings" or the ppa:graphics-drivers/ppa in the command-line.

Machine learning and deep learning in astronomy: from 2016, sparse after after mid 2019

Machine learning has a long history in astronomy, but since around 2016 deep learning (DL) only got traction. Here I summarise effords and publications of DL in the astrophysical community.

The main field of ML applications in astrophysics is object classification. With source counts now ranging into the 10⁷-10⁸ for most surveys, machine learning is put to use to allow the classification of a large number of sources which would otherwise need an infeasible amount of manpower:

• CATALOGING ACCRETED STARS WITHIN GAIA DR2 USING DEEP LEARNING 07/2019 - Three hidden-layer FCN with 4-9 initial input features, trained on simulations for 2-class classification.
• Classifying galaxies according to their HI content 06/2019 - SVM perform best in specisifity and is hence used over a DNN
• [Morphological classification
