Show HN: I build one absurd web project every month https://ift.tt/KFgY1xD

Show HN: I build one absurd web project every month I’ve been building absurd, mostly useless web projects for fun — and I publish one every month at absurd.website. These are deliberately non-functional, weird, sometimes funny, sometimes philosophical — and usually totally unnecessary. Some examples: Sexy Math — solve math problems to reveal erotic images. Trip to Mars — a real-time simulation that takes 7 months to finish. Add Luck to Your e-Store — add a waving cat widget to boost your conversion via superstition. Microtasks for Meatbags — the future: AI gives prompts, humans execute. Invisible Lingerie — it’s sexy. And invisible. Artist Death Tracker — art prices spike when artists die. We track that. Open Celebrity — one open-source face, shared by all. Together we make her famous. I just enjoy exploring what the web can be when it doesn’t try to be “useful”. Would love to hear what you think — and absurd ideas are always welcome. https://absurd.website June 3, 2025 at 01:22AM

Show HN: GoogLLM – Google search that returns Markdown instead of HTML https://ift.tt/Y2NJZ3e

Show HN: GoogLLM – Google search that returns Markdown instead of HTML As part of my bigger goal to make the web more agent-friendly, this weekend i decided to tackle google. The "AI-native" search APIs like Tavily and Exa exist, but they require setup and don't actually use Google's results. So I built something simple - a proxy that takes Google search URLs and returns the results as clean markdown instead of HTML. You literally just change "google.com" to "googllm.com" in any search URL. ```bash # Returns 500KB of HTML: curl " https://ift.tt/9mkJwB0 " # Returns clean markdown: curl " https://ift.tt/K7pD4ei " ``` *What it does:* - Serves normal HTML to browsers (so humans can use it normally) - Returns markdown to everything else (curl, fetch, LLM agents) - Supports all Google search types: web, images, news, scholar, shopping, etc. - No auth needed for testing (10 requests/hour free) *Technical approach:* - Content negotiation based on Accept headers - Caches results to avoid hammering Google - Simple pricing: 0.5¢ per search after free tier I built this over a long weekend because I was tired of writing HTML parsers for every project. The whole thing is designed around a single principle: make Google search results consumable by LLMs without any complexity. *Questions for HN:* - Is this approach too simplistic? Should search APIs be more complex? - How do you currently handle search in your LLM applications? - Any concerns about the proxy approach vs. building from scratch? The llms.txt documentation is intentionally comprehensive (2500 tokens) so any LLM can understand and use it immediately. Live demo: https://googllm.com API docs: https://ift.tt/UeHYpdo Would love feedback on the approach and any edge cases I might have missed. https://googllm.com June 3, 2025 at 12:37AM

Show HN: MBCompass - Android Compass App https://ift.tt/oFRYALX

Show HN: MBCompass - Android Compass App Hey HN, I built MBCompass, a lightweight, privacy-friendly compass app for Android. It works fully offline, doesn’t ask for unnecessary permissions (no GPS, no internet), and is open source. Most compass apps out there are bloated or ad-heavy. I wanted something clean, fast, and featurish. So I made this! It’s only ~1.7 in size and uses a low-pass filter to smooth sensor readings. I’d love feedback or thoughts – especially from others building simple, privacy-first apps! https://ift.tt/tmN6oqI https://ift.tt/FqtBDvP https://ift.tt/FqtBDvP June 2, 2025 at 09:28AM

Show HN: Purpose Reminders – One simple, positive act emailed monthly to all https://ift.tt/ozsEjdt

Show HN: Purpose Reminders – One simple, positive act emailed monthly to all Hi HN, I built Purpose Reminders ( https://ift.tt/wxOp0Mj ). Our first monthly action – "Leave a positive review for a local business" – goes out June 1st (very soon!). The core idea: What if thousands of us did the same small, positive act each month? You get one email, choose to act or skip (no pressure), and then see the collective, anonymous impact. It's 100% free, built with Next.js/Supabase/Resend. My attempt at a simple way to foster some collective goodwill. What do you think of the concept? https://ift.tt/wxOp0Mj June 1, 2025 at 03:21AM

Show HN: Changefly – Rebuilding the foundation of privacy and authentication https://ift.tt/qkZ4biR

Show HN: Changefly – Rebuilding the foundation of privacy and authentication Lukas here, founder of Changefly. For those of you who might remember neworder.box.sk and astalavista.box.sk, I was one of the admin's at a very young age. Fast forward to 2018, I set out to help people regain their privacy. Google invited us into the Google Cloud Startup program which led to the creation of Changefly. After years of truly challenging work and thousands of iterations, Changefly ID was born. Changefly ID solves the problem both users and companies face on a daily basis... spam, scams, bots, account takeover attacks. At face value it looks like an ordinary code, but in fact, it is an encrypted security code that only the user knows and has access to use (a distributed anonymous authentication code). Changefly ID has a lot of flexibility -- replace traditional authentication (which you absolutely should do) or use secondary for multi-factor authentication (a good stepping-stone). It also includes end-to-end communications with your users through Changefly (not email, sms, or other unsecured channels). Additionally, the Changefly app data is also end-to-end encrypted as is the local data. We made access to Changefly ID easy and free with our Developer API. Changefly ID really does stop bots, spam, scams, and other threats from getting anywhere near users or their accounts. p.s. A big thanks to Tom (HN moderator) for their help! https://ift.tt/wAX9Dfu May 31, 2025 at 02:17AM

Show HN: Icepi Zero – The FPGA Raspberry Pi Zero Equivalent https://ift.tt/H0yjEgm

Show HN: Icepi Zero – The FPGA Raspberry Pi Zero Equivalent I've been hacking away lately, and I'm now proud to show off my newest project - The Icepi Zero! In case you don't know what an FPGA is, this phrase summarizes it perfectly: "FPGAs work like this. You don't tell them what to do, you tell them what to BE." You don't program them, but you rewrite the circuits they contain! So I've made a PCB that carries an ECP5 FPGA, and has a raspberry pi zero footprint. It also has a few improvements! Notably the 2 USB b ports are replaced with 3 USB C ports, and it has multiple LEDs. This board can output HDMI, read from a uSD, use a SDRAM and much more. I'm very proud the product of multiple weeks of work. (Thanks for the pcb reviews on r/PrintedCircuitBoard ) (All the sources on github under an open source license :D) PS.

Show HN: Asdf Overlay – High performance in-game overlay library for Windows https://ift.tt/CenxKLu

Show HN: Asdf Overlay – High performance in-game overlay library for Windows I am making a open source overlay library. Game overlay is for rendering contents on top of game screen. Representative examples are Discord and Steam in-game overlay. They are complicated because it has to hook rendering part of a game. Asdf overlay provides easy to use interfaces for rendering on top of game screen. I recognize game performance degradation due to overlay rendering, so GPU shared texture was used to avoid CPU framebuffer copy. Asdf Overlay is capable of rendering full screen overlay without noticeable performance loss. https://ift.tt/S4KFaxN May 30, 2025 at 11:57PM

Show HN: Clean Simple DNS Lookups https://ift.tt/j9R4Tws

Show HN: Clean Simple DNS Lookups Hey HN, Last weekend I vibe-coded a cool website that lets you do easy DNS record lookups. I know you can just use dig or nslookup, but oftentimes I'm too lazy to remember the syntax, and there are less technical users who need to manage DNS entries but aren't comfortable with the command line. We debug customer DNS issues often at ImprovMX, and we typically link to tools like mxtoolbox.com to point out DNS record issues. But those tools seem quite bloated and from the 2000s. I wanted something super clean & simple, and there were a few features I thought were ergonomically needed but lacking: - no confusing dropdowns or syntax for DNS lookup, just put in your domain or subdomain - click-to-copy for all values - header-links so we can provide URLs that will direct another user to an exact domain and which record we want to reference This was SUPER FUN to vibe code! The frontend was pretty much one-shotted with lovable. It's amazing how good AI is when working on a clean slate with all the latest popular frameworks (react, tailwind, shadcn, etc.). And I spent the next few hours making small tweaks with cursor. The backend is a dead simple python flask server. Both are hosted on render.com <3 I love how simple and value-oriented render.com is. It's always the provider that gives me the least headache when I want to just launch and forget something. Give it a try and let me know what you think! https://inspector.improvmx.com May 30, 2025 at 12:21AM

Show HN: I built an AI tool that generates click-worthy YouTube thumbnails https://ift.tt/vMCtzDH

Show HN: I built an AI tool that generates click-worthy YouTube thumbnails Hey HN! Software engineer here. As an amateur youtuber, I've been struggling with thumbnails, especially since I don't have any design or editing skills. Decided to give it a try and make my own automatic thumbnail generator. Me being an ADHD person, made sure that there's no parameter tuning and shape choosing and fuss like that, just simply give prompt and generate thumbnail. Increased my CTR from 1.2% to 2.3% (faceless fantasy books niche on youtube) Thumbnail X (completely free for now) - https://thumbnailx.com/ Just wanna add that this is by no means a perfect thumbnail maker for huge YouTube moguls with millions of subscribers but I'm sure it's gonna be extremely helpful for beginner youtubers and medium size channels struggling with thumbnails. Tools used: 1. Cursor for development (shoutout to claude oppus 4.0) 2. Few image generators (primarily ideogram, but leonardo ai, deep ai and gpt 4o as fallbacks) 3. Few llms (chatgpt, claude, gemini for validating images and prompt enhancement) 4. AWS and Redis for storage & caching 5. Digital ocean for hosting and db 6. Python https://thumbnailx.com/ May 29, 2025 at 02:51AM
