Even Newton's laws had exceptions, i.e. general relativity. No theory in physics is perfect, and neither are the theories in this article (they're just a lot less perfect). The usefulness of laws is in their simplicity and their predictiv

I work on large distributed systems. I've found that Go is a much cleaner and simpler language than C++ or Java, by far. You get the compiled speed and control over memory layout of C++ with the garbage collection of Java. The concurrenc

For me, Go has replaced C++ and Java for systems work. All of my projects at work for the past 6 months have been done in Go. I don't think we'll be going back. But, really, good systems are based on well-defined protocols, which makes th

The new FTC privacy report is certainly worth discussion, but this hit piece smells like a submarine. Had anyone ever heard of the Interactive Advertising Bureau, subtly brought into the article about half way through?

Does anyone know why the TSA even gives you the choice to opt out of the backscatter machines? You can't opt out of the metal detectors. It seems like the default policy would be for the new machines to be mandatory as well.

What are you waiting for? Just try it! There are already many public packages (see http://godashboard.appspot.com/package ), and a tool called goinstall. And there's tons of community involvement, if you'd have a look at the mailing lis

Actually, according to your own blog post on the subject, Gilbert and Lynch define a partition tolerance as: “The network will be allowed to lose arbitrarily many messages sent from one node to another” There's a huge world of diff

Are you sure? Availability in the CAP theorem is a state, as are (P)artition and (C)onsistency. Your system can't be simultaneously consistent and available in the presence of a network partition. The A in CAP doesn't mean always availab

How do you explain Paxos, then? How does a dropped packet prevent the system from responding to queries? How about if I broadcast every response 10 times to everyone I know? How many packets must be dropped for the system to be considere

by dadkins 16y ago
Of course it will become either unavailable or inconsistent (or both) during a network partition. That's the essence of the CAP theorem. But what does it mean to tolerate a partition? As if the system has a choice? Any CA system is claimi

by dadkins 16y ago
Paxos is the quintessential example of a highly available, consistent system. It is available as long as more than half of the nodes are up and able to communicate with each other. It remains consistent, regardless of the failure pattern.
79.
by dadkins 16y ago
Not quite. What I'm saying is that a dropped packet or a failed node are not partitions as far as the CAP theorem is considered. A distributed system is considered available if "every request received by a non-failing node [results] in a

I think the author, like many recently exposed to the CAP theorem, is confused about the meaning of partition tolerance, leading to ridiculous conclusions. Partition tolerance does not mean your distributed system can't be consistent and av

I should add that it's the massive network switch that makes this all possible. You can scale disk I/O by adding disks, and you can scale in-memory sorting by adding cores and memory. But it's awfully expensive to buy your way out of a bo

It's hardware. They have have 52 servers, each with 16 disks which I assume are capable of I/O at 100MB/s. That's an aggregate disk I/O rate of 83.2 GB/s. Their network switch provides 10Gbps connectivity between each pair, which implies

That's strange that you suggest master/slave replication as a way to achieve consistency and availability. If you lose your master, you can't take writes and are thus no longer available. And if your slaves are behind the master, then rea
