Hey, it's HighScalability time:
- Google I/O to world: Just try to keep up with us. You can't. But go ahead and try. Nah na na na nah...
- 17 billion: Google Cloud Messaging messages per day with 60ms latency; 1B page views: 500px; 121 billion: edge graph using Titan; 4 billion hours: hours watched on Netflix per quarter; 4.5 trillion: BigTable transactions per month
- Quotable Quotes:
- to3m: As with any time you make plans for the future, sometimes you get it wrong. Ars longa vita brevis, and all that.
- Callaghan’s law: a given row can’t be modified more than once per RTT
- Josh Haberman: I had an epiphany one day when I realized that the kernel is nothing but a library with an expensive calling convention.
- fread2281: Insane speed calls for insane measures.
- Luke Gorrie: hardware really wants to run fast and you only need to avoid getting in the way -- not too hard if you write the whole stack to match your application, but very hard if you depend on abstractions and misunderstand what's going on.
- Francis Stephens: This exposes an important, and to me non-obvious, property of concurrency. That it's not the locking that's really hard, it's how to be sure that every piece of related data is included in the lock (or STM).
- @jamesurquhart: "Complexity is a characteristic of the system, not of the parts in it." -Dekker
- Colin Scott: out of all the datacenter links types, the average downtime was 0.3 days. This translates to roughly three and a half 9’s of reliability, an order of magnitude greater than WAN links.
- @adocortes: GPU vs CPU 40x faster for image processing in clusters
- Really fast growth really does happen says someone somewhere: Dots game from Betaworks hits 100 million game plays in first 2 weeks.
- If you love something you should set it free or lose everything. Fred Wilson observes: This is a classic case of the innovator's dilemma. RIM felt that letting BBM out in the open would make it easier for Blackberry users to leave. So they kept it proprietary. For way too long. Now they no longer have a dominant smartphone franchise or a dominant mobile messenger franchise.
- When Big Data ecosystems start merging it's not the end of the world, but building a different world: Amex to tap big data (TripAdvisor) to expose fake reviews.
