Presenting programs for execution via various presentable media
The disclosure provides for presenting programs in a scripting language. Examples include receiving a data stream containing computer executable instructions in an interpreted language; generating a verification code; publishing, on a media, the data stream and the verification code; reading, using a sensor, the published data stream and verification code at a reader node; receiving user input; based at least on the verification code or the received user input, determining permission to execute, by the reader node, the computer executable instructions; and based at least on determining that execution is permitted by the reader node, executing at least a portion of the computer executable instructions using an interpreted language execution environment on the reader node. For some examples, the media includes a matrix barcode (e.g., a QR code) or a smart card. Some examples leverage a remote verification node and/or a remote library of executable functions.
