Monetizing the Web
The Revolution will not be monetized by Bob Garfield
Read that. Here are my personal notes.
Problems making money with advertising.
Supply of too many pages with ads depresses demand.
Click-through rate less than 1%. Nobody does it on purpose.
Central advantage, ability to mine data, target people with relevant ads.
People get a creepy sense of privacy invasion.
This is being investgated.
Facebook has a great database for knowing your interests.
Facebook mostly gets money for third-party ads shown elsewhere.
Google search allows for targeting interests right at the moment.
Some hobbyist magazines have ads that readers value as much as the content.

Scalable Datastores
Personal notes on
"10 Rules for Scalable performance in 'Simple Operation' Datastores"
By Michael Stonebraker and Rick Cattell.
From
JUNE 2011 VOL. 54 NO.6 COMMUNICATIONS OF THE ACM 75
The Dominant data storage systems all look about the same today but many new ones are coming.
Systems - Link
New kinds of stores for simple-operation (SO) databases
Key-value Stores - each object has a key and a payload
Dynamo
Voldemort
Document Stores - objects with a variable number of attributes
CouchDB
MongoDB
Extensible Record Stores
- variable width record sets, partitioned vertically and horizontally
BigTable
Cassandra
SQL DBMSs - retain SQL and ACID (Atomicity, Consistency, Isolation, Durability
MySQL Cluster
Ten Rules
Look for shared-nothing scalability
High level languages are good and need not hurt performance
Plan to carefully leverage main memory databases
High availability and automatic recovery are essential
Online everything
Avoid multi-node operations
Don't try to build ACID consistency yourself
Look for administrative simplicity
Pay attention to node performance
Open source gives you more control over your future
