zerowidth positive lookahead | Jump Point Search Explained -- When we reach a node with a forced neighbor, we stop jumping rightward and add the current node to the open set for further examination and expansion later. Weve already assumed that paths above and below us are handled via other nodes, and we havent stopped because of a forced diagonal neighbor. Since we know how to jump ahead in these directions, we can look there first, and if neither of those directions find any nodes worth looking at, we can move one more step diagonally and do it again.

HKSAR Government issues statement on Edward Snowden -- Since the documents provided by the US Government did not fully comply with the legal requirements under Hong Kong law, the HKSAR Government has requested the US Government to provide additional information so that the Department of Justice could consider whether the US Government's request can meet the relevant legal conditions.

This is gartners preferred term for the neither-here-nor-there category of hardware that includes devices like Chromebooks, tablet/PC hybrids and non-traditional phablets, and Gartners guess is that whatever impact they will have on sales will be to the detriment of tablets rather than PCs or smartphones:
