These are their definitions from Microsoft Documentation. ntext (National Text): Variable-length Unicode data with a maximum string length of 2^30 - 1 (1,073,741,823) bytes. Storage size, in bytes, is two times the string length that is entered nchar [ ( n ) ] Fixed-length Unicode string data. n defines the string length and must be a value from 1 through 4,000. The storage size is two times n bytes. When the collation code page uses double-byte characters, the storage size is still n bytes.

YouTube disappears from Samsung Smart TV

This happened on our Samsung Model UN46F7500AF Smart TV purchased in 2013 but the Model began selling in 2012. Speaking to the Samsung support team in USA gives me the feeling that YouTube created a new platform and that the older TV (Prior to 2012) does not support the new YouTube platform. I will have to pursue this matter with YouTube site for confirmation. In Summary, the reason YouTube disappeared is not because of Samsung, but because of YouTube's platform changes according to Samsung. ... (more)

Day 8: A long bus ride from Vienna to Prague. There are places to stop in between for lunch and breakfast. We stopped at a roadside restaurant at a place called Melikana about an hour before reaching Prague. It's a buffet style lunch with lots of buses arriving simultaneously making it a run around carrying platters. Food is OK. Coffee too but not as good as in Budapest. There are charging stations for smart phones and ATMS. They accept Euros or Czech currency. They have only pay toilets, better take Euros or Korunas. We reached Prague late in the evening and had our group dinner a... (more)
