Team, I've got an interest in data processing for higher dimensional
objects so have been putting in a bit of thought about how best to
represent sometimes quite nested data structures in KDB/Q. Using the
Apply function has become part of my routine ...
Hi All, I am currently looking into scraping data using BeautifulSoup4
in embedPy. My issue is that I am having difficulty accessing the list
of lists produced by the method find_all from a BeautifulSoup object. I
have ran the below code in python an...
Hi, I have set up some visualisations using Kx Dash and am looking to

python library having output in a nonstandard python data type. To get
around this, you convert the output to standard Python data types when

I worked this out myself eventually. The trick is to write an analytic
that takes in data, converts it to JSON and then writes a new vega
script around it. That is then passed back to the vega element in the
dashboard via a viewstate from a query map...
Hi Laura, Thanks for the invite! I have been using KDB and Q for over 2
years now and what a journey it's been. I had used it at work in an
Australian bank and for a Masters in Complex Systems. Now, as well as
still using it at work, I'm doing a Doct...
