async/await in Python

 Concurrency is not something I have much experience with and all of the new async/await/asyncio stuff in Python was kinda giving me headaches. So, when the humble bundle I bought had the book Using Asyncio in Python, I was excited. I tried reading it on a weekend a couple of weeks back and I got a headache. I picked it up again last weekend and worked through the examples as I was reading the book, which helped tremendously.

The book also linked to a couple of very useful talks, which aided in improving my understanding of this new world.

David Beazley on Concurrency

Yury Selivanov - async/await in Python 3.5 and why it is awesome

Get to grips with asyncio in Python 3 - Robert Smallshire

A couple of colleagues of mine at work also recommended two books - "Seven concurrency models in seven weeks" and "High Performance Python". For now, I want to get better at using async/await/asyncio and gain a deeper understanding. I'll probably keep watching more talks regarding cooptive concurrency in the meanwhile.

Animation using GNUPlot

Image
Animation using GNUPlot I've been trying to create an animation depicting a quasar spectrum moving across the 5 SDSS pass bands with respect to redshift. It is important to visualise what emission lines are moving in and out of bands to be able to understand the color-redshift plots and the changes in it. I've tried doing this using the animate function in matplotlib, python but i wasn't able to make it work - meaning i worked on it for a couple of days and then i gave up, not having found solutions for my problems on the internet. And then i came across this site, where the gunn-peterson trough and the lyman alpha forest have been depicted - in a beautiful manner. And this got me interested in using js and d3 to do the animations and make it dynamic - using sliders etc. In the meanwhile, i thought i'd look up and see if there was a way to create animations in gnuplot and whoopdedoo, what do i find but nirvana! In the image, you see 5 static curv

Thoughts on the National Deep Tech Startup Policy

The Principal Scientific Advisor to the Government of India published a draft policy to support and nurtue the unique requirements of Deep Tech startups in India. I just finished reading it and put together a few comments in a FOSS United forum thread . I will probably read it again a week or so later and try to update my comments on the thread with any new insights/thoughts I have.

Arxiv author affiliations using Python

So, I wanted to get author affiliation information from papers on arXiv. arXiv provides with an API to bulk query their database and get information. Following that, I look for the attribute 'arxiv:affiliation' in the html data. Here's the code - import urllib from BeautifulSoup import BeautifulStoneSoup   url = 'http://export.arxiv.org/api/query?search_query=all:astro&start=0&max_results=1000'   data = urllib.urlopen(url).read() soup = BeautifulStoneSoup(data) #print(soup.prettify()) #list = soup.findAll('arxiv:affiliation') #for i in range(len(list)): #        print list[i].contents   test = [tag.string for tag in soup.findAll('arxiv:aiffiliation')] Now, the problem I'm having is that I'm getting affiliation of all authors which I want to split into sets of affiliations of authors of a paper, which I'm stuck on at the moment. Once I get that part, I can move on to the next part of this pet project, displaying these
