Some time ago I was thinking that it wouldnt be hard to make software and connects phone to computer and sends the text as Morse code trough prank calls. So you would have free international communication device. Only extremely slow.
Couchurfing is great. I have been using it for few years already. Its completely different way to travel. Most people take you straight into their lives - take you out with their friends, show local pubs, shops, parks or concerts that other way wouldn't get int tourist route. Its more of a view into local culture and life not just visiting landmarks and talking with other travelers in hostel. Hostel are also fun. Hostels are like going to meet with other travelers. Couchsurfing is like visiting a distant friend. And you can also have both of them. Just because you stay in hostel doesn't mean that couchsurfers don't welcome you. You can still meet for a drink or party or walk around city. Its more of a network for meeting local friendly people than just crashing their couch.
I have occasionally used php over the years, but not lately. Soon I will probably have to take up project with it again. So I wanted to go trough a book or two. But everything I found have rather bad coding style, just the one for what php if famous for. What would be good source to learn more advanced features and good practices of producing quality php code?
