I feel like I've learned so much already after having lived in Barcelona for only four months. I'd like to share some of what I've learned now. But only the most important things. I'll start with tech lingo. This one is quite a doozy, because it follows absolutely no standard whatsoever, and knowledge of how to say a techie term in Spanish can only come from saying it wrong ten times in a row and having everyone look at you like you're an idiot.

1. dot com = punto com
2. youtube = yo - ew - too - bay
3. google = google (but go - oh - gull is also acceptable)
4. google earth = google airth
5. giga- = *cough up some phlegm and then say "eegah", but just say it like Jay-z if you're catalan
6. router = roo - tare
7. cable = kah - blay
8. mouse = rah - tone
9. CD = say - day
10. DVDs = day - ew - bay - dayz
11. record a CD = grabar un disco
12. open ports = abrir puertas
13. emule = eh - moo - lay
14. backup = bah - KUP
15. copy/paste = coh - pee - pah - stay
16. hatch = ah - chh *breathe out
17. click = cleek
18. firefox = phi - air - fokes
19. wi-fi = wee-fee
20. network = la red
21. FTP = effay tay pay
22. DNS = day innay essay
23. DWG = day ew bay do blay hay ** or ** day do blay ew bay jay
24. 3d = trace day
25. google maps = google mops
26. polyline = poe lee lee knee ah
27. google it = BOO skah low in google
28. ACDSee = ah see dee see (this one always gets me)
29. 3d Studio Max = three dee studio mox
30. Viz = beece
31. Maya = ma Yah
32. Photoshop = foto chope
33. database = bah say day dah toace
34. images = ee mah chase * catalan
35. system variables = variablayce del entorno
36. path = poss
37. password = contra saynyah *or* clah vay *or* poss - war - d
38. server = servidor
39. more.

and that's all i can think of for now, but i'm sure i have more somewhere. And the last tip I can offer is:

don't come to Barcelona to learn or practice spanish, especially if you're American.
