Setting default applications in Ubuntu

 

This post covers how to set default applications in Ubuntu from the command line using the mimeopen script.

Example : Open .fits files always on ds9

ds9 is a program (stored in /home/bin/ds9) that allows astronomers to explore data (.fits files) taken at the telescope. Here's what I did to set that as the default application for opening any .fits file:

ubuntu@ubuntu:~/$ mimeopen -d 22_23.fits
Please choose a default application for files of type image/fits

    1) home  (home-usercreated-1)
    2) Siril  (org.free-astro.siril)
    3) Munipack  (xmunipack)
    4) Atom  (atom)
    5) Other...

use application #5
use command: /home/bin/ds9
Opening "22_23.fits"   (image/fits)

Communicating and downloading data from the James Webb Space Telescope

We use the DSN ([Deep Space Network](https://www.jpl.nasa.gov/missions/dsn)) to communicate with the observatory. We receive data when we have a contact with Webb using a DSN antenna The DSN has three sites around the world, each positioned 120 degrees apart. There are antennas in Goldstone, California; Canberra, Australia; and Madrid, Spain. This allows us to communicate with Webb at any time of day Each of the [DSN complexes](https://www.nasa.gov/directorates/heo/scan/services/networks/deep_space_network/complexes) has different types of antennas, including 70-meter (230-foot in diameter), 34-meter (111-foot in diameter), and 26-meter (85-foot in diameter) antennas. The DSN complexes use the 34-meter antennas to talk with Webb with the 70-meter antennas as a backup. The DSN supports different radio frequency allocations, such as the S-band and Ka-band frequencies that Webb uses. -band has a lower bandwidth, and we use that to send commands to the spacecraft (e.g., start recorder play

Giving up on PDF annotations

Image
What I wanted: To be able to seamlessly take notes on PDFs with the annotations automatically synced to my notes. Additionally, if I make any changes to any of the annotations at any time, they must also immediately sync back to my notes.  Is this possible?: Note that this workflow for HTML is possible using WebResearcherJS (https://github.com/kvgc/WebResearcherJS-extension) along with Joplin.  However, after exploring this issue for a considerable period of time, today, I give up on my pursuit to integrate PDF annotations directly with my research workflow. I am prepared to label this task as 'possible but time-consuming and challenging to implement'. Solution adopted: Instead, the solution I adapted was to iframe the pdf on to a webpage and use WebResearcherJS to take notes on the webpage. Thus far, this pipeline works like a charm and eliminates the need to directly deal with PDFs. Notes: Python: I wrote a python module that extracts PDF annotations . One possibility is
