I'm working on interactive explorations of algorithms and machine learning. Small, visual, hands-on demos that help build intuition by letting people tweak code/parameters and see how things behave in real time.

Nice! Is it a website, an app, a Jupyter notebook,...?

I’m a remote dev building an iOS app called Springus. You add a few pics / your closet basics, and it suggests outfits based on what you already own. It’s less “fashion app” and more “tiny morning momentum hack.”

Would love feedback from other WFH folks — a weird amount of my productivity comes down to how I start the day.

We're doing so much planning and reviewing with coding agents like Claude Code and OpenCode.

I spent a day over break building a better UX for reviewing coding agent plans.

Plannotator - Annotate and review coding agent plans visually, share with your team, send feedback to the agents with one click.

I'm still working on my PDF search engine for desktop: https://www.docgoblin.com/ I'm implementing a bookmark utility right now and hope to add support multiple E-books format in the near future.

A one time payment app - interesting (I'm also working on something with similar moneytization solution). How are things going? I'd love to know the experience of another solopreneur, what stack are you using? I wonder - What are you using to parse PDFs and extract the text? I found that is a nightmare when was doing something similar for WithAudio (my app). - Are you just extracting the text or you are doing any pos…

Things are going slow, but it is a passion project so it's ok :) A few people have bought a licence and it seems most people who try the app are very happy with it so I'm happy too.

The app is entirely in Java, with javaFX for the UI and Lucene for the search engine. To read and render PDFs I use PDFium.

I’m working on ApprovIQ, a tool for construction certifiers. Someone who wants to get something built will work with one of customers to get their project approved before construction. They’ll typically go back and forth on dozens of documents each of which must be checked over for compliance - drainage, water quality, fire safety, the list goes on.

Despite being intensely technical and detail-oriented, certifying construction is still mostly done by hand over email!

Our niche is full of folks whose lives we can improve with a portal for document management & comms, plus a sprinkle of AI for document understanding.

If you know someone - anyone - wrangling too many documents via email. Please reach out.

Thinking of new ways to visualize market data in 3D like this helical candlestick chart: https://cybernetic.dev/helix

Love the matrix UI with the minimap!

Thank you, I appreciate it! I'm also planning to add a graph visualization of the correlation matrix.

I'm working on Tech Posts ( https://techposts.eu ), a Hacker News for Europe! Since the last time I posted on HN it's gained a decent amount of traffic and users. I'm particularly happy with the jobs section, which is growing into a high signal-noise source for European tech jobs: https://techposts.eu/jobs The reason I started this website is because so much incredible innovation and growth in Europe flies under the…

Bug on home page:

"Ask TechPosts.eu: Is there an EU Cloudflare alternative? I'm interested in CDN, DDoS mitigation and basic web security." Links to https://techposts.eu/post/153

"3 comments" below it links to https://techposts.eu/post/154

It looks like the latter is correct.

I would have sent feedback direct, but I can't see an about page or anything.

Script to auto-rename screenshots with Claude Code

I'm sure there are a ton of other projects out there that do this, but I couldn't find one that fit my needs exactly, so I threw this together in a few hours.

claude-image-renamer uses Claude Code CLI to analyze screenshots and rename them to something actually usable. It combines OCR text extraction with Claude's vision capabilities, so instead of "Screenshot 2025-12-29 at 10.03.10 PM.png" you get something like "vscode_python_debug_settings.png".

A few things it does:

    Handles those annoying macOS screenshot filenames with weird Unicode characters
    Uses OCR to give Claude more context for better naming
    Keeps filenames clean (lowercase, underscores, max 64 chars)
    Handles naming conflicts automatically
If you're on macOS, you can also set this up as a Folder Action so screenshots get renamed automatically when they are saved to a folder, typically ~/Desktop. This is useful if you take a lot of screenshots and hate digging through "Screenshot 2025-12..." files later.
