- Mac computers. Also I have only basic knowledge about Linux. I do have a Linux server I have installed myself :-)
- Finance systems, CRM, specific programs for some profession
- Selling hardware
This is not worth my while as my profit will be low and I have to take risks as the law states 2 years warranty and I most often only have one year.
I am happy to purchase things on your behalf as long as the trade is directly between You and someone else.
- Repair of hardware components. Does anyone do that these days ? Buy a new part.
- Design of home pages, texts, colours and so forth. Not my strongest side. I can do the tech and I have done this homepage.
- Surveillance and physical protection from thieves. Alarms and video.
- Project management of development projects
Actually I would like to but I have no practical experience. My bachelor was HCI/UX (Human Computer Interface, User eXperience.) and CD (Contextual Design).
- iPhone and tablets. I am sure I can handle them but I prefer android myself and have far more experience with them.
