When using gdal to read data from HDF, netcdf, and other datasets, two steps are generally required: first, to obtain the sub-dataset in the dataset; second, to read the image data from the sub-dataset obtained in the first step. There are many subdatasets in a general HDF image, such as frequently-used modem_data. When you use ENVI to open the image, the following dialog box is displayed to allow users to select the subdataset to be opened (1 ).

Security personnel found hundreds of apps infected with Porn clicker Trojans in the Google Play app store
Recently, ESET security personnel found hundreds of apps infected with Porn clicker Trojans in the Google Play app store.Porn clicker Trojans are infected by disguising them as popular game applications. They use names and icons that are very similar to valid applications. For example, researchers discovered over 30 fake Subway Surfers games and over 60

Using the complement Code not only fixes the zero sign and two encodings, but also represents a minimum number. this is why the range of the 8-bit binary code expressed by the original code or the back code is [-127, + 127], and the range indicated by the complement code is [-128,127].
Because the machine uses the complement code, the 32-bit int type commonly used in programming can be expressed in the range of [-231,231-1] Because the first digit represents the symbol bit. you can save on

The MoD in the 2,3 method refers to the modulo operation, with MoD 12 =4 16 divided by 12 after the remainder is 4.
So the clock back dial (subtraction) can be replaced by forward (addition)!
