RTO & RPO are two non-functional requirements that affect the business continuity management. While RTO has much broader impact, both of these factors should be determined objectively based on the need and cost factor in mind.
Renaming a file on a Mac is not so obvious; plus an Automator script to rename files.
One would think that renaming a file on Mac must be easy given the user-friendliness of Mac OS. Turns out, it is not so obvious.
To rename a file in Finder, you click on the icon preceding the file name once and then click on the file name again. This will highlight the file minus the extension. Now you can type the new name to rename.
Having said that, I was able to create a Automator script that will pop-up a dialog to rename either part of the file (base or extension) by right-clicking and selecting the Services option.
Following is the snapshot of the Automator script.
Main features of MongoDB
MongoDB is an open source, document-based database management system. Designed for the data and scalability requirements of modern internet applications, MongoDB features dynamic queries and secondary indexes; fast atomic updates and complex aggregations; and support for replication with automatic failover and sharding for scaling horizontally.
Explores the difference between the leading document databases, CouchDB and MongoDB
Excerpt from Mongo DB in Action – “Few databases identify themselves as document databases. The other well-known document database apart from MongoDB is Apache’s CouchDB.
CouchDB’s document model is similar, although data is stored in plain text as JSON, whereas MongoDB uses the BSON binary format.
Like MongoDB, CouchDB supports secondary indexes; the difference is that the indexes in CouchDB are defined by writing map-reduce functions, which is more involved than the declarative syntax used by MySQL and MongoDB.
They also scale differently. CouchDB doesn’t partition data across machines; rather, each CouchDB node is a complete replica of every other.”
