Scope
These terms cover bsm3d.com and its sub-sections. Using the site means accepting them. The site is a personal and professional platform for sharing technical writing, tools and research; it is not a shop and nothing is sold here.
Articles and documentation
All articles, guides and documentation on this site are written by Benoît Saint-Moulin and remain his intellectual property. They are provided for educational purposes.
- You may read, share links to, and quote this material, and you may use it freely in a teaching or learning context - for lessons, course preparation, student projects, academic research and sharing among colleagues - provided the source is credited.
- Written permission is required for anything beyond that, in particular commercial or professional use, translation or adaptation, wholesale republication, or integration into other documents or training material.
- Requests for permission go through the contact form.
Tools, code and downloads
The software projects presented here - Spectra Workbench, BSM Tools, BSM Karma Builder and the open-source repositories - are each governed by their own licence, supplied with the project itself or stated in its repository. Spectra Workbench, for example, is released under the MIT licence. Where a project's licence differs from these terms, the project's licence takes precedence for that project.
Downloads are provided as-is. You are responsible for checking that what you download suits your setup, and for keeping backups of your own work before running any tool against it.
No warranty
Everything on this site is provided "as is", without warranty of any kind. Techniques, software versions and interfaces described in the articles change over time, and content that was accurate when written may become outdated. Nothing here is a guarantee of any particular result, and it remains your responsibility to test and validate anything before relying on it in production.
To the fullest extent permitted by law, no liability is accepted for any loss or damage arising from the use of this site, its content, or the tools linked from it.

They are referred to descriptively, for technical discussion and education. No affiliation with or endorsement by these companies is implied, except where a collaboration is explicitly stated.
Third-party images and assets reproduced anywhere on this site remain the property of their authors and are credited where used.
