make this about validating we trained each shark using their real advice, tweets, and how they publicly validate ideas so when you pitch, it actually feels like them roasting you not just a generic AI response Here you go: we trained each shark using their real tweets and advice on how they validate ideas so when you pitch your idea it actually feels like getting feedback from them not just a generic AI telling you "great idea" Short, clear, accurate so should i qoute the first post or reply for this Quote your first post for this one. This way: new people who see the quote will click the original tweet to understand what it is it brings fresh eyes back to your main post every time each quote tweet acts like a new post in the feed So the order is: First post — the main one you already posted Quote that post — with the "we trained each shark" tweet Quote that post — with how each shark thinks (marc asks MRR, pieter says ship faster etc) Quote that post — with the early access l

Browse and discover Substacks that were submitted to Hacker News.

I made an HN clone that lists only Substacks posted here. - Why? Over the years, I've discovered some great blogs here, so I thought it would be nice to have a filter for them. - Why only Substacks then and not blogs more generally? Because it's easy to query for "substack.com" in the public HN Algolia API (see below). Plus, hnblogs was already taken :) - What about substacks on custom domains then? At the bottom of the page there is a form to submit a custom domain. The site attempts to auto-validate that it is a Substack. If that fails, it is marked for manual review (which I'll do every once in a while). Approved ones will be included in the results. - How? I use HN's Algolia API to fetch substack stories by searching for "substack.com" in the url. I do this via a CloudFlare worker that has 3 separate cron triggers: (1) fetches new stories every 10 minutes and saves them in a KV store. (2) runs 2 minutes after the first, computes hot stories from new ones by simulating HN's scor

Complete security quizzes across 5 levels to prove your code understanding.

I vibe-coded an anti-vibe-coding app. Yes. I used AI to build a whole academy that trains you to stop blindly shipping AI code. Five levels. Security quizzes. Badges. A streak. The whole “read the error before you panic” curriculum. It’s like building a gym while eating pizza on the treadmill. Play it here → https://videcodingacademy.web.app This post was also vibe-coded. Happy Vibe Coding 😂 submitted by /u/rontop151 to r/SideProject [link] [comments]
