I am creating table like this: CREATE TABLE foobar (id uniqueidentifier, foo text, bar text, PRIMARY KEY (id)) How to insert or generate value for id field in table foobar? Mike Sherrill 'Cat Recall' You can argue that SQLite doesn't support data types at all. In SQLite3, you can do this, for example. sqlite> create table test (id wibblewibble primary key); SQLite will happily create a column with the "data type" wibblewibble. SQLite will also happily create columns with the "data types" uuid, guid, and SuperChicken. The crucial point for you is probably how to automatically generate a uid.

I am working on DICOM gated (PET) data. I would like to artificially create a DICOM image series which includes gated data. I am inquiring on the increment values of SOPInstanceUID which labels each image slice in each phase or gate. These have different values for each slice in a gate and are incremented between gates but I can't find out the logic to how this value is chosen. Is there a reference to where and how these values are written? Multiple algorithms to generate DICOM UID are explained in this answer with their drawbacks. As per DICOM specifications , all UIDs including

I am getting a list of ApplicationInfo Objects with packageManager.getInstalledApplications(0) and attempting to categorize them by whether or not they are a system application. For a while I have been using the technique described here , however after seeing that in my application, some of the apps were not in the non-system apps list (such as Facebook , which when available asks the system to install itself on the SD card). After next reading the actual documentation for ApplicationInfo.FLAG_SYSTEM , and understanding that it doesn't actually filter system apps, I am now looking for a new
