Hi everyone,

I wanted to share DWN.BRIDGE, a desktop utility I've been building and recently open-sourced under the MIT License. It's written in C# WPF, targeting .NET 10.

It acts as a secure, local-first bridge between web-based LLMs (like Google Gemini) and your local environment, allowing you to run queries and scripts without uploading raw data to the cloud or paying for expensive API billing loops.

Here is how the core tool works:

- Zero-Knowledge Schema Extraction: It parses database metadata (SQL Server, SQLite, Excel, CSV) locally and sends only the empty schema structure (headers, data types) to the web UI. The generated SQL runs locally, so raw rows never leave your machine.

- Local Compile Loops: If the LLM generates a local script, it compiles and runs test suites offline, returning stdout/stderr compilation errors back to the model for self-correction.

- Execution Firewall: Every destructive action, shell execution, or file write pauses and requires you to click "Approve" on a local popup window showing a git-style diff of the action.

The repository is fully open-source, and I'd love to get feedback on the sandboxing model, the architecture, and the zero-knowledge security approach.

Straight from France (thanks to a life-saving "double boxing" and a complicit nephew...), that's when it arrived: the Zenith ZVM-122-A. For those who don't know, this is not a simple amber phosphor monitor. It is the perfect companion for the Apple II, not only for its aesthetics (that inclination is pure 80s industrial art), but for the sharpness of the 80-column characters that made the official Apple monitors of the time pale. "Holy Grail"? Well, personally I looked for it for years and when it appeared at unreasonable prices I didn't want to fall back on the Philips ones that appear more often...

I had a mantra 122 122 122...
Yes, because it is the only Zenith abbreviation with yellow phosphors, 121 123 124 all green...
When I saw the box in an ad... I was shocked... I had no doubts, by zooming in you could read it clearly. I don't like boxes, personally I don't care much, but I know what the 'piece' is worth when combined with its original packaging, even if I don't consider myself a museum collector. I didn't know if it worked, obviously the French lady selling it didn't know what it was... I even got a good price, let's say affordable within the limits I've always set for myself. Deep Amber Phosphorus: It's not yellow, it's that warm gold that never tires the eyes, even after hours of BASIC. Condition: Arrived with its original box but without the vintage Styrofoam. A miracle it survived unscathed. Video Performance: As you can see from the photos, the geometry is still almost perfect and the focus is razor-sharp: In the photos, you can also see it at the top of the stack with the Apple IIe and the ProFile... a piece of computing history that shines again. Are there any other "amber fans" in the sub, or are you all fans of the classic phosphor green?

Straight from 1999, another technological jewel that was forgotten too soon, another successful restoration. It has everything, Mail, Word, Spreadsheet, Notes, time zones, telephone contacts and everything else....

Oops no, not everything, no telephone or video camera of course and oh no colors! ;-)
