Exclusive Jurisdiction is a concept whereby only one Grand Lodge will be recognised in any geographical area. If two Grand Lodges claim jurisdiction over the same area, the other Grand Lodges will have to choose between them, and they may not all decide to recognise the same one. (In 1849, for example, the Grand Lodge of New York split into two rival factions, each claiming to be the legitimate Grand Lodge. Other Grand Lodges had to choose between them until the schism was healed.) Exclusive Jurisdiction can be waived when the two over-lapping Grand Lodges are themselves in Amity and agree to share jurisdiction (for example, since the Grand Lodge of Connecticut is in Amity with the Prince Hall Grand Lodge of Connecticut, the principle of Exclusive Jurisdiction does not apply, and other Grand Lodges may recognise both).
When can Exclusive Jurisdiction be waived?
when the two over-lapping Grand Lodges are themselves in Amity and agree to share jurisdiction

In the 1990s, Dell switched from using primarily ATX motherboards and PSU to using boards and power supplies with mechanically identical but differently wired connectors. This meant customers wishing to upgrade their hardware would have to replace parts with scarce Dell-compatible parts instead of commonly available parts. While motherboard power connections reverted to the industry standard in 2003, Dell continues to remain secretive about their motherboard pin-outs for peripherals (such as MMC readers and power on/off switches and LEDs).
What part of their motherboards does Dell not reveal the specifications of?
pin-outs

In simple terms the structure of the Alps consists of layers of rock of European, African and oceanic (Tethyan) origin. The bottom nappe structure is of continental European origin, above which are stacked marine sediment nappes, topped off by nappes derived from the African plate. The Matterhorn is an example of the ongoing orogeny and shows evidence of great folding. The tip of the mountain consists of gneisses from the African plate; the base of the peak, below the glaciated area, consists of European basement rock. The sequence of Tethyan marine sediments and their oceanic basement is sandwiched between rock derived from the African and European plates.
Where are the top of the nappes derived from?
the African plate
