In 1966, two Brazilian men were found dead on Vintém Hill under bizarre circumstances that continue to perplex investigators and conspiracy theorists alike. Lying side by side, their bodies were discovered wearing matching lead masks—shields with no eyeholes—alongside cryptic notes. Were they victims of a cult ritual, a failed experiment, or something even more otherworldly?

MP3•Trang chủ episode

Can you tell if a Ruby gem is really thread-safe or not? And how do you fix a seemingly thread-safety issue that can be something else entirely?

We had no idea. So we asked Nate Berkopec to help us. Nate is an expert in Ruby performance.

The verdict: nuking all shared global mutable state in your Ruby code is a bad idea if you don't know what you're doing!

Listen to this episode to learn:
- How and why faker-ruby became thread-unsafe, especially for Puma users
- Questions to ask yourself when trying to debug thread-safety issues
- Shared global mutable state is not always the villain, and is not the source of all thread-safety issues
- Nate's "watch-out" list of things that can cause undesired behavior when running multi-threaded Ruby applications: Constants, Class Variables, and Rack Middleware.

They did all of that by themselves, the team was just Preetam and Sankalp, and Sankalp was the only engineer. As they say on their website, they are "A small team with a big heart". SuperLemon is a WhatsApp plugin for Shopify stores serving over 20k users with 1.5k paying customers. It recently crossed 30k dollars in MRR, and all of this growth happened in about 14 months. They are now building DelightChat, a customer support tool for small and medium-sized direct-to-consumer & e-commerce brands running lean teams, and recently started hiring and growing the team. Highlights: How they did market research before writing any line of code and how being a little "impatient" with growth is a good thing for a founder How they scaled the app to 20k users with a team of 2 people (1 engineer) by using the K eep I t S imple S illy (KISS) principle How distribution is the most important thing for a micro-SaaS and why they decided to target the Shopify marketplace How they prioritize features and make their customers happy while having a very lean team How to acquire customers every day for the next year Why you should build a business that allows you to have freedom and live a good life We also asked them if they ever received an offer to be acquired or to get VC funding Links: DelightChat SuperLemon MicroSaaS Guide Preetam Nath's Twitter Sankalp Jonna's Twitter Sankalp's engineering blog Notes and Transcript…
