Abstract: To address loss of access to computing instances in a cloud computing environment, techniques are introduced for moving an application between computing instances in the cloud computing environment. A computing service captures baseline or delta snapshots of the state of the application running on a first computing instance. A baseline snapshot is indicative of the full state of the application, and a delta snapshot is indicative of changes in the state since a most recent snapshot was captured. Responsive to receiving an indication that the first computing instance is to stop servicing the application, the computing service stops the application from running on the first computing instance and moves data from the captured snapshots to a second computing instance. The computing service resume execution of the application on the second computing instances and captures snapshots of the state of the application at the second computing instance.

Abstract: A refrigerator and an anti-condensation method for the refrigerator. The refrigerator includes a first storage compartment, a second storage compartment adjacent the first storage compartment, a separation wall separating the first storage compartment and the second storage compartment, and a heater in the separation wall.

Abstract: A one-pot method is used to prepare a fused pyrazole-type compound substituted at nitrogen on 2-position, specifically an indazole-type compound substituted at nitrogen on 2-position. In the method, after azidizing a halogen in a substrate, without post-processing, R-NH2 can be directly added to proceed a ring-closing reaction with an aldehyde group, so as to give the fused pyrazole-type compound substituted at nitrogen on 2-position. For example, by using 2-fluoro-4 methoxy-5-nitro benzaldehyde as a raw material, the indazole-type compound substituted at nitrogen on 2-position can be obtained via azidation and ring-closing steps, and then a series of indazole derivatives can be produced by means of a hydrogenation reaction and a condensation reaction.
