Techniques perform sample selection. Such techniques involve: in response to receiving a query time range for samples input by a user, obtaining a plurality of groups of samples from a sample set, each group of samples being collected within a corresponding time range. Such techniques further involve: determining a relationship between the query time range and time ranges corresponding to the plurality of groups of samples. Such techniques further involve: determining, based on the determined relation and from the plurality of groups of samples, a group of samples with a corresponding time range matching the query time range. Accordingly, these sets of samples may be presented accurately and efficiently to the user in a selective manner.

Embodiments of the present invention relate to a method and apparatus for adjusting throughput of a storage device. The method comprises setting input/output (I/O) delay time of the storage device to be threshold delay time, the threshold delay time being below initial I/O delay time of the storage device. The method further comprises obtaining measured throughput of the storage device, the measured throughput being associated with the threshold delay time. The method further comprises updating the I/O delay time based on a difference between the measured throughput and a target throughput of the storage device to update the measured throughput.

A hand held blower/vacuum device includes an impeller mounted in a scroll housing and a handle by which the device may be suspended and which is rotatably mounted to turn between vacuum and blower positions. In both of the blower and vacuum positions a longitudinal axis of the grip generally lies in an upright plane that passes through a center of gravity of the device, and the grip is disposed above the center of gravity, such that the device hangs below the grip in different balanced orientations in the blower and vacuum positions.
