General caution: Chrome OS is a secure OS by design, but this has at least one key consequence. If you change your Google account password, you will still be required to enter the old password the next time you access each Chrome OS device. Devices are encrypted with that password, so the OS needs to decrypt using the old password then re-encrypt using the new one. If you forget your old password you will lose access to your Chrome OS device data. As always, make sure you keep backups up to date.

Fast User Switching

If you have multiple Chrome OS accounts (Say, work and play), you can quickly sitch between them without logging out:

@LlewBot, does @denverlibrary have The Hobbit?

The full list of recognized library twitter handles is below below. Queries are addressed by first looking up Google Books to match title to ISBN, and then looking for candidate ISBNs in the target library's site on the Library.Link network. Please note that LlewBot only searches for books at present. For further enquiries please e-mail [email protected].

MicroXPath outline

MicroXPath is based on XPath 1, except for sequences, borrowed from XPath 2. MicroXPath adopts this approach. The results of all MicroXPath expressions are sequences.

Sequences

MicroXPath provides a syntax for creating sequences, borrowing from XPath 2.0/3.0. The following are the examples of expressions that construct sequences, taken from 3.4.1 of the XPath 3 spec. They have the same semantics as in MicroXPath.

(10, 1, 2, 3, 4) results in a sequence of five integers.
