A few days ago Tal Galili posted a message about some controversies concerning the future of R. Having read the discussions, especially those following Ross Ihaka's post, I have come to the conclusion, that, as usual, the problem is money. I doubt there would be discussions about dropping R in its present form if the R-Foundation were properly funded and could hire computer scientists,

Hello, I tried making a donation via the centos.org website but was blocked by PayPal. I tried today and a few weeks ago. The error I got in both instances was: "The card you entered cannot be used for this payment. Please enter a different credit or debit card number." This strikes me as a strange response.

Hi, Just wondering if anyone has already developed a mocking approach to stub out the Paypal interface so that one can test on an internal PC which doesn''t provide a means for PayPal to callback to your webserver? (i.e. once the app is deployed to the hosting provider it would then work as PayPal could then hit the application with the specified URL). Anyone already solved this? Would

I charge my customers through PayPal, but recently faced a fraud which previously had only heard about. Somebody registered a few accounts, paid online with paypal (as my service is only prepaid) and started making expensive long distance calls. In fact the IP registering the accounts was from Florida, and IPs making calls were from Africa. After about 20 minutes the first payment was reversed.
