I'm working on a self-service product for SaaS that predicts which users will churn, are ready to buy or upgrade. This is something I desired to have at my previous company, and I just thought this would be the right time to build it.

You?

I'm working with my family managing our supermarket. It is not cool at all.

I got a Bachelors degree in CS at UFPE. I have been studying for a while to get back to software developer career.

If you have some kind of purchases database you could practice data science on it.

I've been looking at Apache Arrow (https://arrow.apache.org/) and trying to figure out how to integrate it into the browser. It's an in-memory data format, and the idea is to share the same data chunks amongst various clients, but shared memory in javascript got nuked by Spectre, unfortunately. I'd like for the same data to be accessible from, eg, multiple tabs or session-wide without copying, so it's like a shared cache that mmap's or shmat's its objects into each consumer on a read-only basis.

If we get this to work we make data a lot easier to play with in the browser; the user can load the data once and then play with the presentation or slice and dice it in multiple ways without overhead.

Tesults (https://www.tesults.com) - it’s cool because for teams of say 10 or more doing automated testing they can focus on writing tests and maintaining automation infrastructure and allow this to handle reporting. It also gets better and better every day. Just today, launched a feature where csv files attached as part of a test case (like for captured performace metrics data) are automatically visualised as scatter charts with x and y axis fields being selectable.

You could so some pretty cool stuff. Have you been hyper optimizing it?

Product shelve to sale ratios?

80/20 type optimizations on revenue by skus?

Traffic flow maps?

I'd love to hear some result or stories if you do end up doing some of this.

I'm working on a brainstorming/idea generation site as a side-project. No idea if people would want this.

Which lead me to down the path of wondering if there are any idea pitching sites. In the meanwhile, I just created a subreddit(/r/ideaspitch) which could serve that function for the time being, just so that I can relax and focus on my original idea again...

So yes, brainstorming/idea generating tool.

I'm working on a bunch of lexer and parser related tools for personal use.

The reason they're cool is that it automates a lot of the tedious, error-prone stuff that I've been doing by hand as I experiment with grammars and the like.

Sure, there are a ton of tools out there to generate lexers and parse tables and such. But using them doesn't help me understand how they were built.

And using them doesn't produce the same sense of accomplishment or, at least for me, /depth/ of understanding.

I try to document the tools as best I can so that fellow students who are interested in such things can learn or make use of them. :)
