- Quotable Quotes:
- Similarity : There is no canonical schema anymore. Instead you should ask: What high-volume queries will I need to serve with my data? Then work backwards from there.
- @kvirjee : Dis/Agree? -- "there is no problem but scalability, and architecture is its solution"
- @robpegoraro : Eternal vigilance can be crowdsourced.
- Didn't Bill Gates say once that 48 bits would always be enough for an ID? Well, Oracle ran out of bits: Fundamental Oracle flaw revealed. 64 bits, that's the ticket, ipv6 went 128 bits.
- The day Kodak died: We developed the world's first consumer digital camera but we could not get approval to launch or sell it because of fear of the effects on the film market... a huge opportunity missed.
- PeteSearch with Five short links that are long on good.
- StorageMojo asks: If SSDs are so great, shouldn’t we see the results in TPC-C benchmarks? And answers: They are, and we do. The most expensive top-10 SSD result is some 15% cheaper than the least expensive disk-based result
- Netflix shows how they achieve Auto Scaling in the Amazon Cloud: 1) Scale up early, scale down slowly, 2) Provision for availability zone capacity, 3) Without the proper configuration and testing it can do more harm than good.

- A thread on How to store unique visitors in cassandra revealed Countandra, a hierarchical distributed counting engine on top of Cassandra. Something I've never heard of before, but looks cool. Matt Dennis has some time series data modeling advice. Common tasks are surprisingly hard in a lot of systems.
- Availability, Data Locality, and Peer-to-Peer Replication. Peer-to-peer replication is a special and magical kind of replication, it works in a ring or mesh to make sure that one row’s updates will magically spread to all servers. You’d think that this would mean every server is equal, right?
