Ich möchte Stadtpolitik in Aachen für alle verständlich machen.
Mein aktuellstes Projekt aachen-transparent.de ermöglicht es, die öffentlichen Informationen aus dem städtischen Ratsinformationssystem modern und benutzerfreundlich aufzubereiten.
Dazu habe ich das bereits existieren Open-Source Projekt Meine-Stadt-Transparent erweitert und für die Bedürfnisse in Aachen angepasst.

Aachen Transparent ist ein Projekt, dass ich ehrenamtlich im Rahmen des Open Data Labs Aachen ins Leben gerufen habe.
Es versucht einige der Unzulänglichkeiten des Ratsinformationssystems der Stadt Aachen zu umgehen.
Dazu nutzt es dessen öffentliche OParl Schnittstelle um die dort hinterlegten Informationen über eine moderne Oberfläche zugänglich zu machen.
GoSƐ is a modern and scalable file-uploader focusing on scalability and simplicity.
It is a little hobby project I’ve been working on over the last weekends.
The only requirement for GoSƐ is a S3 storage backend which allows to it to scale horizontally without the need for additional databases or caches.
Uploaded files a divided into equally sized chunks which are hashed with a MD5 digest in the browser for upload.
This allows GoSƐ to skip chunks which already exist.
Seamless resumption of interrupted uploads and storage savings are the consequence.
And either way both upload and downloads are always directed directly at the S3 server so GoSƐ only sees a few small HTTP requests instead of the bulk of the data.
Behind the scenes, GoSƐ uses many of the more advanced S3 features like Multi-part Uploads and Pre-signed Requests to make this happen.
Users have a few options to select between multiple pre-configured S3 buckets or enable browser & mail notifications about completed uploads.
A customizable retention / expiration time for each upload is also selectable by the user and implemented by S3 life-cycle policies.
Optionally, users can also opt-in to use an external service to shorten the URL of the uploaded file.
Currently a single concurrent upload of a single file is supported.
Users can observe the progress via a table of details statistics, a progress-bar and a chart showing the current transfer speed.
GoSƐ aims at keeping its deployment simple and by bundling both front- & backend components in a single binary or Docker image.
GoSƐ has been tested with AWS S3, Ceph’s RadosGW and Minio.
Pre-built binaries and Docker images of GoSƐ are available for all major operating systems and architectures at the release page: /stv0g/gose (Releases) .
GoSƐ is open-source software licensed under the Apache 2.0 license.
I consider the current state of GoSƐ to be production ready.
Its basic functionality is complete.
However, there are still some ideas which I would like to work on in the future:
