In plain words

DevTools is an offline-first application designed for developers that provides a collection of utilities for common coding tasks like date formatting and model parsing. Created by Anh Nguyen, it aims to accelerate development workflows while keeping user data local and secure.

Lots of little useful tools! The problem is I keep forgetting I have the tools when struggling thru issues like date formatting, model parsing, etc.. Great app! Lots of little useful tools! The problem is I keep forgetting I have the tools when struggling thru issues like date formatting, model parsing, etc.. Great app! There are tons of insanely aggrivating limitations and developer hard-coded idiocies that will have you deleting this app quickly...Just for one example: you're only allowed to indent your CSS in the following options: 2 spaces, 4 spaces, 1 tab, minified. What fool decided I would never want 1 space, 3 spaces, 5 spaces, or 2 tabs? I specifically downloaded this app thinking…from apps.apple.com

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

    I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
