astropy@GSoC Blog Post #3, Week 3

So, it's the start of the 3rd week now. I will be virtually meeting Aarya and Moritz again Tom.

For the past few weeks now, I have been pushing commits to a Draft PR https://github.com/astropy/astropy/pull/11835 on GitHub. I wanted to have something working quite early in the project, in order to be able to pinpoint accurately when something doesn't work. This is why I started with directly adding the cdspyreadme code within Astropy. Afterwards, I am also writing the code from scratch. As more of the required features from cdspyreadme get integrated into cds.py, those files and codes added earlier will be removed.

About the reading/writing to Machine Readable Table format, in fact I wrote about it briefly in my GSoC Proposal that I could attempt it as an extension. I don't have an opinion on whether or not it should have it's own format classes etc. However, since the title of my GSoC project is to Add a CDS format writer to Astropy, I would prefer to work on the CDS format writer first and then on the MRT format. The MRT header anyway appears to be a bit simpler than the CDS header, so there shouldn't be much difficulty in the extension.

So, in a nutshell, this is my workflow:
  • Try out directly using cdspyreadme from within Astropy.
  • Add CdsData.write method.
  • Add a ByteByByte writer.
  • Write features to add complete ReadMe to the Header, starting off with having both ReadMe and Data in a single file.
  • Have features for writing separate CDS ReadMe and Data file.
  • Further work on some specific table columns, for instance, those containing Units and Coordinates.
  • Add appropriate tests along the way.
  • Resolve other issues that come up.
  • MRT format reader/writer.

I have completed the first three tasks and will now work on the fourth. I think by the time this finishes, a separate CDSColumn.py won't be required. I can open another PR which adds the Data writer, in the meantime.

Let's see how it goes!

Why I write?

Initially I wanted to title this post,  On writing Diaries , however this thought-provoking question is far better. Although it may take me a long time to be an author per se, more or less, I have been a continuous writer since my seventh grade. What started with jotting down non-sense farce on daily routines during the middle school years, has now grown into some fierce rhetoric on vast ranging topics important to me in general. So, what is it about writing that I like so much? Unlike most of my friends, what has made me go on for so long now? Why do I write? And why do I plan to write more vigorously, more persuasively and more indiscriminately than ever in the coming future? Well, there isn't any plain simple answer to these. I write because I like to write. I write because it gives reality to all of these thoughts inside my head which couldn't find an route through the tongue. I write because it often makes me feel good. I write because I find this the best way to convey my

Review: Homo Deus by Yunal Noah Harari

Homo Deus: A Brief History of Tomorrow by Yuval Noah Harari My rating: 5 of 5 stars It took me a long time to finish reading Homo Deus . And I think the long duration was well worth it. Homo Deus is not the ordinary everyday stale non-fiction that one comes across. It is a masterpiece in its own right. But for the Sapiens , I don't recall having read any other book that stimulated thinking to the degree Homo Deus does. The book starts off almost right away from where its predecessor, Sapiens , ended. A New Human Agenda , that of seeking eternal youth , bliss and divinity , is put forward for the 21st Century. Since the dawn of Humankind, the persistent goal of any population has been to have sufficient food to quench hunger, to have health measures to fight infections and diseases and to be at peace with neighbouring kingdoms. With the advent of the modern technology and the unprecedented progress it has made over the last few decades, the goals have changed now. Rest of the
