This month we hosted a superb lineup of speakers at the KX Community Meetup in the Millennium Management offices in New York.&nbsp;

In case you missed it, we had Aaron Davies demonstrating how to use q to deconstruct metadata in cellular images:

&nbsp;

&nbsp;

Next up,&nbsp;Jack Kiernan demonstrated application development using Python on kdb:

&nbsp;

&nbsp;

Followed by Phineas Porter using PyKX and q to solve vector challenges:

&nbsp;

&nbsp;

And lastly, we had a fantastic demo from Ian O’Dwyer walking through the pro-code deployment of kdb Insights, using YAML files and Docker Compose:

&nbsp;

&nbsp;

We’d like to thank everyone for attending and following up the demos with such great and interesting questions.

I would like to comment on the topic of binary parsing. I also had a use case for this and started writing parsers directly in q, but I ran into performance issues when trying to read large files with thousands of variable-length records, as well as when needing to parse lots of incoming messages in real time. So I decided to switch to C, and I also expanded on the idea so now I have a library that can be customized with a DSL that describes the structure of the file and can turn a byte stream into a q object and vice versa. It has some extra features like variable-length arrays with a size field, arrays with a terminator rather than a size field, and case fields which have a different schema depending on the value of another field. It can be found here:&nbsp;gyorokpeter/qbinparse: Customizable binary data parser (github.com)

I have added the outlines of the PNG and zip formats as examples.
