Data Handling and Data Security

Suspended NEBcutter sessions can be resumed. Using the default settings, the program stores all project data (sequence, enzyme selection, display settings, and manual entry) on the server and deposits an associated session code on the user's computer. When the user later reconnects, these session codes are returned to the server, data from the user's earlier projects are retrieved, and results of those sessions are reconstructed. The identifier codes are randomly generated, unique numbers, and are stored in browser cookies. Each code is account-specific, so its use requires that the subsequent connection is made through the same log-in account. Another consequence is that people sharing an account also share each other's data. This data sharing can be avoided by using the ''delete project'' button on the main menu at the end of a session. Alternatively, users can block NEBcutter's save-and-resume feature by checking the appropriate menu option on the interface. Completely disabling a browser's use of cookies is another way of increasing data privacy.

The second method of saving and resuming NEBcutter sessions is activated through a menu option. With this option, project data are returned to the user and stored in a local data file, named by the user. To restart the project later, the user needs to upload this file. This second method is designed for reactivation of an analysis after an indefinite suspension of a session. The first method is intended for temporary interruption of a session. After 2 days of inactivity, server-stored session data files are deleted automatically.

By the time a session is reactivated, new restriction enzymes may have been added to the database, or the content of REBASE may have changed in other ways. Suspended sessions can still resume analysis with the original repertoire of enzymes, which makes the reconstruction of earlier results possible.

Concurrent users of NEBcutter do not notice each other, and they cannot access each other's data. For the purposes of troubleshooting, resource allocation, and optimization, NEBcutter administration routines monitor user activity, maintain log files, and compile usage statistics.

Getting Started With Dumbbells

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
