  Preparing for the real costs of cloud computing

Computerworld - At a cloud computing conference in New York in June, a number of speakers pointed out that the cloud is moving past the hype stage and is beginning to deliver tangible benefits to organizations. These improvements include increased flexibility and agility. But moving to the cloud can also mean added costs, some of which might be unexpected, according to IT executives whose organizations have implemented cloud services or are considering them. While these types of costs ...

  Will We Need Teachers Or Algorithms?

Editor’s note: This is Part III of a guest post written by legendary Silicon Valley investor Vinod Khosla, the founder of Khosla Ventures. In Part I, he laid the groundwork by describing how artificial intelligence is a combination of human and computer capabilities In Part II, he discussed how software and mobile technologies can augment and even replace doctors. Now, in Part III, he talks about how technology will sweep through education. In my last post, I argue...

  Signs that you're a bad programmer

1. Inability to reason about codeReasoning about code means being able to follow the execution path ("running the program in your head") while knowing what the goal of the code is.SymptomsThe presence of "voodoo code", or code that has no effect on the goal of the program but is diligently maintained anyway (such as initializing variables that are never used, calling functions that are irrelevant to the goal, producing output that is not used, etc.)Executing idempotent functions multiple times (...

  How to read Haskell like Python

Have you ever been in the situation where you need to quickly understand what a piece of code in some unfamiliar language does? If the language looks a lot like what you’re comfortable with, you can usually guess what large amounts of the code does; even if you may not be completely familiar how all the language features work.For Haskell, this is a little more difficult, since Haskell syntax looks very different from traditional languages. But there's no really deep difference here; you just h...

  Currying in Python

What is Currying? Currying is like a kind of incremental binding of function arguments. Let’s define a simple function which takes 5 arguments: 1def f(a, b, c, d, e):2    print(a, b, c, d, e) In a language where currying is supported, f is a function which takes one argument (a) and returns a function which takes 4 arguments. This means that f(5) is the following function: 1def g(b, c, d, e):2    f(5, b, c, d, e) We could emulate this behavior the foll...

  Why Software Projects are Terrible and How Not To Fix Them

If you are a good developer and you’ve worked in bad organizations, you often have ideas to improve the process.  The famous Joel Test is a collection of 12 such ideas.  Some of these ideas have universal acceptance within the software industry (say, using source control), while others might be slightly more controversial (TDD).  But for any particular methodology, whether it is universally accepted or only “mostly” accepted, there are a multitude of organizations ...

  The trap of the performance sweet spot

This post is about JavaScript performance but I would like to start it by telling a story that might seem unrelated to JS. Please bear with me if you don’t like C.A story of a C programmer writing JavaScriptMr. C. is a C programmer as you can probably guess from his name. Today he was asked by his boss to write a very simple function: given an array of numbered 2d points calculate vector sum of all even numbered points... He opens his favorite text editor and quickly types something ...
