While I am still working on my proseminar, which is taking longer than expected due to some PGI compiler problem (OpenACC 2.0 atomic directive not implemented in PGI 14.1 available at my university
What maybe the reasons for you to leave Facebook? 1. You generate money for Facebook and don't get anything from that, besides the feeling, that you are in touch with people. Actually, you are not. Go out and talk to people or send them a nice email or post-card. Having hundreds or thousands of "friends" doesn't mean anything. Your best friends can probably be counted on one or two hands and the other important people will not outnumber them significantly. 2. Facebook lets NSA use your data or even gives your data to NSA (and other firms) and helps governments and big companies keep track of the data on the internet. You shouldn't support that and yes, even your data is significant. Facebook can track your logins for years and it probably knows better, where you have been last month, than you do. (The implications are probably scary, if you have any secrets to keep.) You will notice, when the airport staff will undress you, because you have been to Egypt last year or something like that. (They will not tell you, that this is the reason, but the computer processing big data will command the staff to search you because of that.) 3. Maybe you don't actually read interesting stuff on Facebook anymore. You just have it and keep track of meaningless things, when you could spend more time reading a book or with your best friend or partner.
If you want to be in touch with me, send me an email to the address provided in the contact and provide information you want me to have such as a phone number, or home address. I will add those to my contacts I keep secured well.
