Back in college, I thought I could compress my phone number by telling people its index in pi, but my 7 digit phone number is at an 8 digit index. I didn’t have the compute to find my 10 digit number with the area code.

By default, it tries to take 80% of your memory. I've found that you need to set it to something much smaller in ~/.duckdbrc `set max_memory='1GB';`

The best way to get software engineers to solve your issue with X is to phrase your question “Why is X so horrible? It can’t even do Y.” The engineers will inevitably reply “That’s so simple. You just need to …” The ecosystem for managing p

I hadn't heard of Opera Unite. It's similar and 10+ years older! Thanks for the kind words - friends have been mostly confused by this project.

This is advice that seems reasonable but is actually pretty harmful. Take a startup with a few users. The senior engineer decides they need pub/sub to ship a new feature. With Kafka, the team goes to learn about Kafka best practices, c

This is a neat idea, but I think the site is a bit too barebones for people to want to trust with their data.

The article does a good job of explaining the difference between WHERE and HAVING. The simplest resource I've found for this is Julia Evans' "SQL queries run in this order" [0], which points out for example that SELECTs

This is quite a bit of infrastructure for an app that hasn't launched yet. If it's not too late, consider simplifying by removing RabbitMQ or Redis. Perhaps even getting rid of both, and only using MySQL. Maybe your workers could

When you first hear Tailwind's concepts, they seem to contradict everything you know about good software design. When you try it out and begin to remember some of the class names, you get into a great state of flow - it's the high

Lots of developers believe that if they think hard enough and choose the right side project, it will succeed. I think the takeaway here is that chance plays a big role. So increase your chances by shippings lots of projects. And a tip to sh

Browser extensions will redirect HTTP to HTTPS as the request is made, so CoffeeShopWifi can't help you there. Most sites will send a redirect to HTTPS, which CoffeeShopWifi does not. So I decided it's safe to make a cert and supp

I have a saas for non-devs to open big CSVs, so code I've written has parsed thousands of garbage CSVs (and failed to parse thousands others). Lots of pitfalls are easy to avoid if you already know them, which it sounds like you do. Th
