Abstract: Techniques for improving packaging systems are described. In an example, a computer system receives item data from a workstation. The item data includes a description of an item. The computer system also receives fit parameters. The fit parameters adjust the fit of items within packaging. The workstation is configured to facilitate packaging of the item. Based at least in part on an input to a packaging decision system, the computer system generates a package decision indicating a package type associated with the packaging of the item. The input is based at least in part on the item data. The packaging decision system is trained based at least in part on packaging data associated with historical item orders. The computer system sends the package decision to the workstation.

Abstract: Multiple different applications are available to a user's device from an application store that is accessed via a network. The applications can be selected for download and installation at the user's device, or alternatively can be selected for running without installation at the user's device. This selection is made by the user, giving the user control over whether an application is installed on the user's device or run without installation at the user's device. When selected for running without installation at the user's device, the application is run on one of multiple different virtual machines that corresponds to the form factor of the user device. A user interface generated by the application running on the virtual machine is provided to the user device for display, and user inputs at the user device are returned to the virtual machine for input to the application running on the virtual machine.
