TDD vs FTT

“I don’t see why I need to write tests for it — *I* wrote this, and it works.”

Categories of developers
  1. 1. Can’t have enough tests: Vanishingly few, but so so useful when it comes to building out fault-tolerant systems
  2. 2. Usually write tests, but occasionally skip ’em for the “Obvious Stuff”: Sadly, most of us
  3. 3. Consider their (passing) tests proof that everything is golden: Annoying, and definitely the ones that will take your system down at an inopportune moment
  4. 4. Write tests only when forced to do so: The worst of the lot, epitomized by the quote at the top of the post. Their development style can be best described as FTT, for “F**k The Tests”.

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...

Spot The Difference — Deep Learning Edition

You’ve played  Spot The Difference  at some point, right? (Of course you did. We  all  did  ). Think about what you actually did when you were trying to Spot The Difference — in fact, just do it again with SpongeBob juggling above. You’re probably doing something like 1. Quick glance to the left. 2. Quick glance to the right 3. “ Spatula on the left. Wonder if there is one on the right? ” 4. “ Yup, there is. Sriracha on the right. Is that on the left? ” 5. “ Nope! It’s a ketchup bottle on the left! And there is nothing on the plate below it! ” etc. To summarize, what you’re basically doing is looking at each image alternately, identifying objects in each image, and trying to find the same object in the other image. As it turns out, what most Deep Learning systems do is something quite different. They basically do something like this 1. Figure out everything in the first image (“ ketchup bottle at 1 o-clock, empty plate at 3 o-clock, spatula at 1...
