Hey, thanks for pointing out Self--I definitely need to dig into fastcore more! One motivation for developing siuba is that the grouped agg you show requires users specify only one operation on one column. E.g. 1. Calculate mean of x Howeve

Hey y'all, creator of siuba here--happy to answer any questions! One piece of context I try to bring into discussions is that the way I test and develop siuba is by livecoding data analyses for an hour [1]. I encounter a lot of argumen

Hey, author of siuba here, I totally agree that subclassing would be a natural choice in python. One challenge there is that users will often get a DataFrame back (e.g. from pd.read_csv), so it requires a lot of casting to the child class.

Interesting approach! I've been working on it from the other angle: having pandas code generate SQL. If you're interested in checking it out, happy to try and show how it would generate the query in your readme! https:/&#x2F

Agreed! It seems like there's a lot of power in having "one to beat". As in, let's get some model up before we worry about one that needs daily updates.

I feel like a lot of these concerns are resolved in tools like R's dplyr. You use mostly the same R code, whether your data is a data.frame, or living in a SQL source. dplyr generates the SQL query for you. By reading the queries it ge

Have you seen the R library dplyr? It is a weirdly powerful data analysis tool, that can also produce SQL queries!

Articles like these are interesting, but what surprises me is that they rarely set up a holistic use case, so most debates imagine how long it would take an expert user to use each tool. But time constraints (eg spent coding) separates expe

This might sound nuts, but I have settled on a three step process that mostly involves keeping most notes in my head. Step 1 is using the method of loci (MoL) to memorize up to 30 things throughout the day. For context, MoL is a strategy

Yeah--we're basically second-order black formatters now. Not writing code that looks nice, but writing code so a tool that writes code will make it look nice.

I would be a bit surprised if this is true, because it implies that when you're writing code that will be formatted you do not think of the reader's experience. This could be the case if you have extreme confidence in the formatte
