Fallacies of Distributed Computing (Oldie but Goodie)

-
Arnon Rotem-Gal-Oz goes through the fallacies of distributed computing with panache.
What?  You've never heard of them?
Well, they are
  1. The network is reliable
  2. Latency is zero.
  3. Bandwidth is infinite.
  4. The network is secure. 
  5. Topology doesn't change. 
  6. There is one administrator. 
  7. Transport cost is zero. 
  8. The network is homogeneous
His summary is particularly poignant
With almost 15 years since the fallacies were drafted and more than 40 years since we started building distributed systems – the characteristics and underlying problems of distributed systems remain pretty much the same. What is more alarming is that architects, designers and developers are still tempted to wave some of these problems off thinking technology solves everything.

Remember that (successful) applications evolve and grow so  even if things look Ok for a while if you don't pay attention to the issues covered by the fallacies they will rear their ugly head and bite you.
Or, to put it differently, - Architects can be stupid, alarmingly so at times.

Cannonball Tree!

Spotted this one just outside the Ravindra Kalakshetra in Bangalore .  Its called the Cannonball Tree , but is - technically (i.e., in Latin, if thats your metier) - Couroupita Guianensis , or ನಾಗಲಿಂಗ ಪುಷ್ಪಾ  in Kannada. The fruits look like Cannonballs (well, d-uh), and the flowers are really quite amazing, and pretty ludicrously distinctive...

Erlang, Binaries, and Garbage Collection (Sigh)

-

The nice thing about garbage-collection is that it is makes memory management absolutely transparent to you Of course, the above is true right up to the point when it stops being transparent, at which point it does a phase change from nice to clusterf**k of biblical proportions .  There are entire posts, books, and suicide notes that have been written about this, and I have no great desire to add to them, save with the minor comment that paranoia about garbage-collection is still justified , albeit only in the edge-cases for most people. That said, I'll give you that Erlang GC is in many ways much, much better positioned in this regard than, oh, Java, but it still rears up and bites you in the butt when you least expect it. ( More information about Erlang's GC vis-a-vis Java here , and Jesper's truly excellent description of Erlang's GC here ).  A story from the past should serve to illustrate this. Once upon a time, in a magical land far far away - well, Her...
