Show HN: Hire big tech employees to appeal account suspensions I used to work for Facebook and Google and constantly got asked questions like "Hey, my Instagram account got blocked for no reason. Could you help me get it back?". I'd say yes, it would take me 10 min to fill out an internal form and 1 week later the account was back. Even years after leaving, I still get these requests. So I built a marketplace for them. Let me know what you think! https://plsfix.co/ May 21, 2024 at 10:42PM

Show HN: I recreated Jeffery Ventrella's "Particle Life" This weekend's coding session was dedicated to recreating Jeffery Ventrella's "Particle Life". As you can imagine, I had a lot of fun with it. I recently saw this here on Hacker News and found it strange that I’d never come across it before.

Show HN: Optigraph – optimum graph network generator https://ift.tt/iGI0ScN

Show HN: Optigraph – optimum graph network generator I've created a tool that helps plan graph networks for the best possible connections between nodes. The idea is for it to be used as a kind of underground system planner. I am still working on improving the algorithms it uses, but please consider checking it out for new ideas/bug catching. https://ift.tt/oPXcrOh May 19, 2024 at 03:00PM

Show HN: SQLFrame – I ran PySpark without Spark on a SQL database https://ift.tt/BoqhELy

Show HN: SQLFrame – I ran PySpark without Spark on a SQL database Recently I open-sourced SQLFrame, a DataFrame library that implements the PySpark DataFrame API but removes Spark as a dependency. It does this by generating the corresponding SQL for the DataFrame operations using SQLGlot. Since the output is SQL this also means that the PySpark DataFrame API can now be used directly against other databases without the Spark middleman. I built this because of two common problems I have faced in my career: 1. I prefer to write complex pipelines in PySpark but they can be hard to read for SQL-proficient co-workers. Therefore I find myself in a tradeoff between maintainability and accessibility. 2. I really enjoy using the PySpark DataFrame API but not every project requires Spark and therefore I'm not able to use the DataFrame library I am most proficient in. The library currently focuses on transformation pipelines (reading from and writing to tables) and data analysis as key use cases. It does offer some ability to read from files directly but they must be small although this can be improved over time if there is demand for it. SQLFrame currently supports BigQuery, DuckDB, and Postgres with Clickhouse, Redshift, Snowflake, Spark, and Trino in development or planned. You can use the "Standalone" session to test running against any engine supported by SQLGlot but there could be issues with more advanced functions that will be resolved once officially supported by SQLFrame.
