The best way to get in touch is by e-mail: I usually check my mailbox(es) regularly, and asincronicity helps. You can find me at

[personal e-mail] andrea dot resmini at gmail dot com
[work e-mail] root at resmini dot net

If you need to send me something large, that is anything that usually gets measured in MBs, please notify me first so I know what to expect.

Now, in case you really are in a hurry and out of computers or devices (well, not if you are using Skype, but never mind), I concede a phone may get handy. If you do not mind hitting a busy line sometimes, you can try

[work phone, Italy] +39 393 9003157
[pers phone, Sverige] +46 073 0771842

Last, if you are the technical geeky, chatty type, instant messaging could also be up to the task, although I usually tend to forget logging in to my accounts. Worth a try, anyway. To IM me, search on Jabber for

[skype, wherever] aresmini (or search Andrea Resmini)
[jabber] vector at jabber dot org

If all fails, either draw you conclusions and dismiss me or try again. Maybe switch approach. Just keep in mind I probably didn't ignore you on purpose (and if I did, you'd know and wouldn't even bother calling in, would you?).
