data-leon··on Show Me the Money: Unveiling the Real Earnings of US College Grads 4 Years Out
Based on our data analysis, we have discovered several key findings related to earnings differences between Ivy League and top public schools, the most lucrative fields, and the top 20 school/major combinations with the highest earnings.

Ivy League vs. Top Public Schools Earnings

Ivy League graduates have significantly higher average earnings (91,867 USD) and median earnings (82,034 USD) compared to top public school graduates, who have an average earning of 66,341 USD and median earning of 58,647 USD. Factors such as program offerings, access to resources, networking opportunities, and perceived prestige may contribute to these differences in earnings. Prospective students should consider these potential earnings against the cost of attendance and personal preferences when choosing between Ivy League and top public schools. Most Lucrative Fields

The top 5 fields with the highest median earnings 4 years after graduation are:

Nuclear Engineering Technologies/Technicians (131,454 USD) Biomathematics, Bioinformatics, and Computational Biology (117,247 USD) Marine Transportation (104,858 USD) Naval Architecture and Marine Engineering (101,744 USD) Operations Research (99,689 USD) Top 20 School/Major Earnings

The top 5 schools with the highest median earnings are Harvard University, California Institute of Technology, Carnegie Mellon University, University of Pennsylvania, and Princeton University. Computer Science and Computer and Information Sciences, General are the most common majors among the top 20 schools/majors. Other high-earning majors in the top 20 include Finance and Financial Management Services, Electrical, Electronics and Communications Engineering, Mathematics, and Computer Engineering. The Massachusetts Institute of Technology (MIT) and University of California-Berkeley both have 3 different majors in the top 20. Median earnings for the top 20 schools/majors range from 168,957 USD (University of Washington-Seattle Campus, Computer Engineering) to 256,539 USD (Harvard University, Computer Science).

data-leon··on Why I quit using SwiftUI
Built an  macOS app (https://posturenet.app) to monitor my posture in real time with SwiftUI last year for fun.

The lack of support for Video and Camera from SwiftUI was the most challenging part for me as a newbie  Mac dev.

Took me a few weekends to get the core part done (ML and algorithm), but hooking up all the UI components and connecting them with the video stream gave me so many headaches.

With that said, it was still much easier for me (complete newbie to  Mac App at the time) to learn and develop in SwiftUI than UIKit.

Hope SwiftUI keeps getting better and  keeps investing in the team.

data-leon··on Show HN: Subreddit Finder – find subreddits based on a topic
Brilliant! Love the idea, I've been thinking of adding a tree diagram or a social graph style exploration tool for subreddit finder, will likely add it soon so people can visualize their relationship and find similar subreddits based on a subreddit they already know.

Fair point, our goal was not to help people spam reddit, instead, I think one should contribute to the community and share their expertise, focus on contributing first.

Thanks @mtmail for your feedback, will take a look and figure out what heppened to perl.

It might be because of our training data, as perl gets less popular, our training data might simply not having enough good data. : )
