Roadmap


A traditional blog post can be thought of as residing in a network, with webpages linking to and from it. However, if one were to naively consider every incoming and outgoing link to this webpage, it can become a bit chaotic. This series is my humble attempt to manually curate a network (a 'roadmap') with interesting content from the internet along with my own commentary as needed. This will hopefully serve as a compass to those who wish to navigate its treacherous seas.

svglue: Templating using inkscape and python

svglue is a small library that takes a template in form of a specially prepared SVG document and fills in text and images to create an output SVG file. The pip version did not work of the box and I ran into the same issue as pointed out here . Link to working tutorial

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...

Zotero to Tiddlywiki5

  Zotero is a great tool but it has been challenging to look up bib and notes taken in Zotero on Tiddlywiki. It is really inconvinient to have to always have to switch between these two apps. Therefore, I wrote this python script which takes the csv that you get from running Zotero's default csv translators and converts it into something that you can import to Tiddlywiki directly. Note that Tiddlywiki does not allow you to import arbitrary JSON files such as   {     'x': 10,     'y': 20 } as new tiddlers. Instead any JSON file that you import must have the following keys to be loaded as a new tiddler {     'text'        : '' ,     'tags'        : '' ,     'modified'    : '' ,     'created'     : '' ,     'title'       : '' } ...
