Show HN: I made a tiny book using a pen-plotter and AI Hey HN, I want to share a personal project: I made a tiny pen-plotted book for my wife. I did everything myself—drawings (with some help from Midjourney), plotting, cutting, and binding. I even used a 3D printer to make a helper tool. It's absolutely over-engineered, but I enjoyed it a lot. Multi-disciplinary projects, especially those with a physical output, are a lot of fun for me. The post covers the process in detail, but if you're interested in anything specific, let me know. Cheers! https://bit.ly/4gIVFLQ February 10, 2025 at 06:52PM

Show HN: Dockershrink – AI Assistant to reduce the size of Docker images https://bit.ly/4gEY8XR

Show HN: Dockershrink – AI Assistant to reduce the size of Docker images For the past few months, I've been hacking around a project I call Dockershrink. It automates a simple task: Take a Dockerfile and optimize its code with the goal of reducing the size of the final Docker image. People don't realize that we can apply some very basic techniques to reduce, for eg, a 2GB image down to just ~100MB: - Multistage builds with light-weight base image for final stage - Remove unused dependencies - Optimizations specific to the tech stack And I feel like I've already done this optimization for my personal projects and backend apps at my job(s) a couple of times. The project currently uses GPT-4o (open source so you can run it locally) and only works for Nodejs projects. There are a couple of reasons why I think dockershrink can be better than using just Vanilla LLM or Github Copilot/Cursor: - Image optimization can benefit from a lot of custom prompting, especially when you have insights about specific tech stacks. Describing techniques deeply in the prompt gave better results than simply asking the LLM to "optimize code for bloat reduction". - A RAG approach will be truly beneficial. I plan on giving dockershrink access to up-to-date documentations of Docker, Bash and all programming languages out there. Additionally, it can be given a few suitable chunks of code to enhance the context. - Analysing custom base images: most orgs have their customized base images. Adding context about these can further help Dockershrink make better decisions. Try it out - "brew install dockershrink" Happy to hear your thoughts! https://bit.ly/4b3seTQ February 13, 2025 at 11:45PM

Show HN: Auto rename downloads by AI and with your own naming rules https://bit.ly/42TpFkZ

Show HN: Auto rename downloads by AI and with your own naming rules Hii HN! We've built a Chrome extension called Cantrips.ai that auto generates meaningful filenames for pdf, txt, and docs downloads. It has tailored formats for major file types like papers, books, financial reports, etc. For example, a paper is always formatted as download date - title - first author's last name - area, so the filename would be 20250208 - Attention Is All You Need - Vaswani - LLM instead of 1706.03762 from arXiv. We are also developing a feature where users can add or adjust their file naming preferences. For example, if you like underscores and download meeting memos a lot, you can add meeting memos = interviewee's name_company_position_topic_date. The reason to build this extension is that my desktop is buried with meaningless and odd filenames, so I often can't find which is the one I want. I have to go to that website and download it again, sometimes the repetition number amounting over (10). More importantly, I desperately want my desktop/finder to look tidy. It feels great when everything is organized, but I don't want to handle the renaming in the mid of my research (and I become a bit lazy later :< Note that the extension hasn't supported downloads from some websites like Github due to technical complications. As a first-time dev, I just realized even a small tool can take much time... but we assume a similar preference feature can be applied to other productivity tools like folder organization or website bookmarks. Happy to get suggestions and learn if you really need such tools. If you want to try the extension, here's the link: https://chromewebstore.google.com/detail/cantripsai-auto-ren... https://chromewebstore.google.com/detail/cantripsai-auto-rename-do/fnaemmlnchphilapbdjejjlhoomcpblk February 12, 2025 at 11:48PM

Show HN: Wordle Charts – insights about Wordle you don't need https://bit.ly/3EHwFr2

Show HN: Wordle Charts – insights about Wordle you don't need Hello HN! I'm a big fan of Wordle and I originally got this idea from seeing people gripe about Wordle suddenly being "harder" than usual. Wondering if this was true, I set out to snoop around the NYT's publicly available data, which gave me some pretty cool insights. I've put some of them on this simple site made with React and Claude. There's a grand total of 7 visualizations, with some fun little touches here and there. My favorite is probably "Clairvoyant Guesses," which shows some (to put it nicely) suspicious day-to-day guessing patterns. There's also a fun little easter egg when you type "cat" and then enter a word into the "Find Word:" box. Let me know if you have any suggestions, and any feedback at all :) Github Repo: https://bit.ly/3EzdeAT... https://bit.ly/4gEQKvs February 7, 2025 at 06:45PM

Show HN: WhisperCat – An Audio Recorder and Transcription Tool https://bit.ly/4aR9nv3

Show HN: WhisperCat – An Audio Recorder and Transcription Tool Hi HN, I wanted to share my first open-source project with you all: WhisperCat . WhisperCat is a small desktop application for recording audio and transcribing it using OpenAI's Whisper API. I built this because I needed something simple and reliable for my own transcription workflows, and now I'm hoping it might be useful to others as well. It's still pretty early stage, but it works well for basic audio recording and transcription tasks. What It Does: Lets you record audio with your preferred microphone. Transcribes audio files automatically via Whisper (OpenAI's transcription API). Supports global hotkeys for recording (e.g., CTRL + R or a custom sequence like triple ALT). Runs in the background (system tray) when minimized. Has a basic microphone testing feature to help you pick the right device. Shows desktop notifications for events (e.g., when recording starts or errors happen). Platforms: WhisperCat is available for Windows and Linux , and there’s also an experimental macOS build you can try if you’re feeling adventurous: Experimental macOS Build You can download the latest release here: https://bit.ly/4jQy2E6 Feedback is welcome! https://bit.ly/4aTxqJD February 10, 2025 at 08:41PM

Show HN: Ricotta – Language Learning to Replace Anki I’ve been tinkering with Ricotta for about a year now and I'm happy to announce it’s ready to for others to use officially. Largely the time has been spent making the project a framework to spin up newer projects quickly which I can share details around if anyone is interested. The app was born out of my frustration with Duolingo drilling me on words I knew. I moved on to creating custom Anki cards and found myself spending ages creating decks. It’s free, uses spaced repetition under the hood, and focuses on helping you learn what you want to without a course structure.

Show HN: Stock Analysis Feels Broken – Here's My Take on Fixing It https://bit.ly/3CwJZy5

Show HN: Stock Analysis Feels Broken – Here's My Take on Fixing It Stock analysis tools are powerful, but I’ve always run into three challenges: 1/ Too much data, hard to digest – Plenty of insights, but filtering what truly matters is time-consuming. 2/ No clear buy/sell decisions – You get the data, but figuring out what to do next is missing. 3/ No way to build a personal strategy – Most tools use preset metrics, but does not help to invest your own way. As a result, I often fall back on stock price and following others' opinions—not ideal. So, I built https://bit.ly/42MIPcr (v0) to simplify key data, let you set your own rules, and turn them into buy/sell/hold decisions. Would this actually help investors, or am I just solving my own problem? Curious to hear from you: Which of these challenges resonate with you? What do you find useful, confusing, or missing? https://bit.ly/42MIPcr February 9, 2025 at 12:00AM
