Show HN: I built a site that tracks short-lived flight deals https://bit.ly/3Z7yUfo

Show HN: I built a site that tracks short-lived flight deals So, this summer I was hunting for a flight from Calgary to Tokyo with WestJet, and I kept seeing these random cheaper flights popping up. I got tired of refreshing the site non-stop, so I whipped up a script to scrape the flight data. It paid off—I scored a roundtrip for $1000 CAD in July! Naturally, I decided to turn this into a full-fledged project and built flight-price-alert.com! Tech details: Built with Go for the backend and SQLite for the database. Added some TLS spoofing to get around Cloudflare’s JA3 fingerprinting that was blocking my requests. Styled the site with PicoCSS—it was super easy and kept things neat. Generated tons of images with Recraft.ai. Seriously, I must’ve churned out hundreds. It was a blast! Hosted on a single EC2 instance with EBS attached for SQLite storage. It’s pretty simple right now, and I’m debating whether to keep developing it or move on. If you have any questions or ideas for improvements, I’d love to hear them! https://bit.ly/3Z0Mkdb August 27, 2024 at 03:32AM

Show HN: I published a book to save you from my software architecture mistakes https://bit.ly/3Ml1PFu

Show HN: I published a book to save you from my software architecture mistakes Hey HN, I just wanted to share that after five months of intense work and countless caffeine-fueled writing sessions, "Master Software Architecture: A Pragmatic Guide" is now available. Writing this book was a crazy time. I entirely focused on it, and it took exactly 753 hours of writing, editing, and image editing & resizing(!) until the premiere. Yes, the last one (images) was a killer. If you ever think about writing a book, reserve a lot of time for it unless someone else does it for you. As a result, I am handing you the nearly 400-page book. It is a guide that will help you connect all the pieces while balancing the focus on understanding the domain and technology aspects, described using a pragmatic approach and super simple language. It is perfect for novice architects taking their first steps in software architecture. It is also an invaluable resource for software engineers looking to understand architectural concepts and those considering transitioning into an architect role. Several guest authors, including Vlad Khononov (Learning Domain-Driven Design book), Oskar Dudycz (Marten, Emmett, Pongo), and Milan Jovanović (.NET & C# educator), shared their views on keys to successful software architecture. Here you can find a free chapter (the first link on this page): https://bit.ly/4g11d5f... To your success, Maciej "MJ" Jedrzejewski https://bit.ly/3yV2Dhe August 26, 2024 at 11:35AM

Show HN: Ward – a file vault written in bash just wanted to share ward, a tool i hacked together to encrypt and manage sensitive files in a vault folder. it's written in bash and meant to be cloned and then stored using git or version control. you don't have to store it that way, it's just why i created it. what ward does: encrypts the files in ./vault/ into a single .gpg file, checks to see if your files have been tampered with, generates totp codes if you need them to recover critical accounts. how to use it: clone the repo, toss your files into the vault directory, and run yarn encrypt. now commit your new [private] repository or save it somewhere. that's it. repo link: https://bit.ly/4g0IqXR feedback welcome, or just let me know if you find it useful. https://bit.ly/4g0IqXR August 26, 2024 at 05:18AM

Show HN: I'm Creating the Next Big Social Media Platform – Rated https://bit.ly/3XfOx38

Show HN: I'm Creating the Next Big Social Media Platform – Rated Hey all, I've been working hard on my side project and will be trying to turn it into my main project now. Rated is a social rating platform for media, places and products. By having everything in one place, its easier to add friends, follow and compare ratings. There are cool data features like similarity scores between each users and predicted ratings for every item. The main aim is to help people discover the best content in a fun and social way. I've made a website (not that pretty yet) and launched on the app stores, but there's a long way to go. Still haven't properly validated the idea and need to get some users. I would love feedback on the idea, landing page and if you are interested in trying it out - feedback on the app itself. https://bit.ly/3XgL9VP August 26, 2024 at 02:01AM

Show HN: Slidde – If you can build a slide, you can build a website The most common problem when making a webpage is that you have to write tedious layout & javascript logic every time. But they are almost the same. I'm trying to limit coding to only styling (CSS). Styling is what we actually customize for each client/webpage. If you try to styling your webpage using dropdowns & radio buttons it would be painful. By enabling selectors like "&:hover" making the styling almost possible for everything. https://bit.ly/3YW1joH August 26, 2024 at 01:31AM

Show HN: I built a dumb directory – tell me I didn't waste my time Hey HN, I've made a groundbreaking discovery: procrastination can lead to questionable projects! While avoiding real work, I somehow created a directory of 130+ AI agents and frameworks. It's like I tried to organize a robot party and everyone showed up. What's inside: - A list of AI agents - Frameworks to build more agents So, HN, before I spiral into an existential crisis: did I accidentally create something useful, or should I go touch grass? P.S. If this somehow becomes the next big thing, I promise to pretend it was intentional all along. https://bit.ly/4dizgEw August 23, 2024 at 04:57AM

Show HN: FOSD – Framework of Operating System Development https://bit.ly/3X0hTBc

Show HN: FOSD – Framework of Operating System Development The FOSD(Framework for Operating System Development) Framework is an innovative and flexible framework for operating system development. It strives to provide flexible resources and tools to help developers design, develop, and deploy operating systems efficiently and effectively. The framework is intended to support various architectures and provide corresponding build systems that facilitate the overall development of the operating system. It gives the already-implemented build system for each architecture that can automatically detect and compile user's source code and create a full operating system with proper bootloader(that's suitable with architecture.) The framework also provides HAL(Hardware Abstraction Layer) that can remedy the difficulty of having to develop all the device drivers for every hardware. Although currently, we're in the early development stage of only having x86 architecture kernel that can barely print "Hello, world", we are planning to implement from the fundamental framework features like interrupt system or basic print system to the file system interface, complicated device drivers(corresponding to the architecture) or even feature for task management. The ultimate goal is to make the operating system development easy and efficient for everybody! https://bit.ly/4cA05Tj August 23, 2024 at 12:10AM

Show HN: Feeedy – A messenger-style note-taking app https://bit.ly/4dXN0V7

Show HN: Feeedy – A messenger-style note-taking app Hey there HN! Happy to share a piece of my labor I've been working on for the past 6 months. The idea for the app came to me when I found out that taking notes in Telegram saved messages and private channels is pretty convenient, but it became a mess real quick. Imagine accidentally sending your to-do list to your boss? And there were no work-related stuff, haha So I decided to solve this pain point of mine by creating a little app, just as a side project. But then I lost my job due to a layoff, so I decided to triple down on my idea, polish it, and make it a SaaS in the hope of making it somewhat profitable if I'm lucky enough, of course. It's been 3 months of non-stop work, hundreds of liters of Red Bull and coffee, failed job interviews, then even more Red Bull and coffee, sleepless nights, and here we are. I'm finally ready to show it to the world. Of course, I keep my hopes pretty low and I'm being realistic with myself. Like, come on, it's just notes, who am I going to impress? Anyway, any questions, feedback, and ideas are more than welcome, and I'll be happy to discuss everything with you guys! https://bit.ly/4ecX0tR August 22, 2024 at 11:27PM

Show HN: Chrome plugin that gives Claude access to search / recent data https://bit.ly/3Av72b8

Show HN: Chrome plugin that gives Claude access to search / recent data Howdy, just wanted to share something I built to improve my experience using Claude chat (web). It'a Chrome plugin that embeds into the Claude chat UI, and that takes the prompt and does an internet search for up-to-date information that Claude doesn't have. The search results are returned into the Claude chat prompt window which allows you use it as context. Behind the scenes the plugin does three things: - Passes the Claude prompt to OpenAI GPT-4o-mini to determine the search terms to use, - Uses Jina.ai Reader API to search and retrieve the top 5 search results (text), - Processing the search results with OpenAI GPT-4o-mini to return only the data relevant to the prompt (to avoid context bloat in Claude) The idea came about because I use Artifacts a lot to do data visualizations, but got frustrated that Claude doesn't have access to recent data natively (yet). I published the plugin to the Chrome plugin store and the code to GitHub: - Chrome store: https://bit.ly/3SXzets... - GitHub: https://bit.ly/3WUpH7F The GitHub repo has screen recording showing what it looks like / how it works. The plugin is free but requires an OpenAI API key, but GPT-4o-mini costs fractions of a cent per use based on my experience using it so far. Hope someone else finds it useful!
