Suggesting that educators and students shouldn’t have to worry about the technology that helps them teach and learn, Google introduced Drive for Education on Tuesday. In the coming weeks, all Google Apps for Education users will gain unlimited data storage on Google Drive, although single files are limited to 5 terabytes in size. Also included with Drive for Education is free access to the Google Apps Vault, used for email compliance, and enhanced auditing for file activity. The company also stressed that data stored in Drive for Education is encrypted and private, saying: “As always, the data that schools and students put into our systems is theirs.”

The Information is reporting that Twitter will introduce its own app development platform — called Twitter Fabric — at its developer conference October 22. Through the service, app developers will apparently be able to verify user logins based on phone numbers, run analytics to test their apps and earn ad money through Twitter’s MoPub network. In exchange, Twitter will be able to gather crucial information for ad targeting and grow the app supply side of its MoPub user base. Twitter is supposedly in talks with ESPN and Target, among others, for early partnerships.

Google has built a linear optimization add-on for its Google Drive spreadsheet application, as well as an associated API for developers. It also open sourced the underlying code via a project called “Glop.” As the company explains in a blog post, “Any time you have a set of linear constraints such as ‘at least 50 square meters of solar panels’ … along with a linear goal (e.g., ‘minimize cost’ or ‘maximize customers served’), that’s a linear optimization problem.” Google, for example, used linear optimization to solve shakiness on YouTube videos. Earlier this month, it open sourced an R library for inferring causation from correlative data.
