How to copy contacts from one SIM card to another

By martinm, in Misc, february 27,2017.

This is based on a true story. Imagine that you have to move your contacts from one SIM card to another. There is an app for this, isn't it? That is... unless your phone is not a smartphone, but an old mobile phone made by a small Finish company that has been taken over by a software editor a few years ago. Unfortunately the new owner company has decided to support only the very latest models. There isn't any official software available to retrieve your contacts on this phone anymore. So you are getting ready to copy all your contacts by hand, one by one... But wait a minute...

By martinm, in Measures and Programming, february 10,2017.

Nowadays, most laboratory measuring tools have an RS232 port and/or a USB port, enabling you to drive them remotely.

Five years ago, we modified our Jura coffee machine, which we nicknamed Josephine, to control it remotely via a web page. The idea was amusing but in fact this feature wasn't really useful as we still had to get up to place a cup in front of the coffee machine. But today, thanks to the Yocto-Proximity, we can do something more useful: We are going to brew a coffee as soon as a cup in placed on the machine.
