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/jQlnT4y

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/kgVHd17 May 19, 2024 at 03:00PM

Show HN: SQLFrame – I ran PySpark without Spark on a SQL database https://ift.tt/bDHr6M5

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.

Show HN: Recall Memory – Your Personal Local Time Machine for Mac Recall Memory is a free Sandboxed Mac App which let's you scroll through time and allows you to "Recall" what you were doing earlier. Recall works by capturing the active window every second and only saves screenshots with significant changes. Making it easy to scroll through what you were doing earlier. All data is processed and always stored locally. https://ift.tt/R1doNTG May 21, 2024 at 05:18AM

Show HN: A VS Code extension to check incompatible CSS I've developed a handy tool for Visual Studio Code that makes checking CSS compatibility very easy for developers. It provides instant feedback on syntax, keywords, types, and function compatibility. It even highlights deprecated, non-standard, and experimental features. https://ift.tt/whrRsBt May 19, 2024 at 11:24PM

Show HN: I Built a Tool to Stop Cold Email Spam https://ift.tt/Fu4ZEyO

Show HN: I Built a Tool to Stop Cold Email Spam Hi HN! I'm Louw, founder of the enterprise insurtech scale-up Root[0]. Over the last 8 years, my inbox has been flooded with unsolicited emails, especially since early 2023. Recruitment services, outsourced software development agencies, and a crazy amount of lead generation services (thanks, Apollo!) drowned my inbox. To solve this, I created Unspam. Initially, it was a simple tool for myself and fellow founders to reduce noise. And it worked — about 10% of my emails were swiftly and accurately categorized as unsolicited messages. Given its success, I've decided to package and share Unspam with the broader community, evolving it into Unspam.io. How it works: 1. Hook up your Gmail 2. Unspam monitors received mail in the background 3. Unsolicited emails are labeled and archived Please try it out and let me know your feedback. What would you improve? https://unspam.io --- [0] https://ift.tt/xNEgvCf [1] PS: I value privacy intensely. Unspam doesn’t record, store, or train on your emails. No need to. https://unspam.io May 19, 2024 at 12:30AM

Show HN: Drivr – VR with real vehicles [video] https://ift.tt/sKc1pza

Show HN: Drivr – VR with real vehicles [video] This project combines VR with a real vehicle that you are controlling (or is controlling itself, in some scenarios). One advantage this has over traditional VR motion experiences is that your senses all agree with each other, thus greatly reducing the likelihood of motion sickness. The go-kart seen in this video is drive-by-wire and steer-by-wire, so the system will not let the player exit the defined safe area. If a player goes off course, the vehicle will take control, and return them to the start. The autonomous capabilities also allow for games where the player can focus on other objectives other than driving, such as target shooting. No infrastructure is required other than the vehicle and an open place to drive (which honestly has been the most challenging part lately). If you're interested in this project, I'd love to connect! https://www.youtube.com/watch?v=Q76X0cnSGHk May 17, 2024 at 12:49AM
