Why Tcl?

Why Tcl?

Introduction

I use [Tcl] as my scripting language of choice, and recently someone asked me why. This article is an attempt to answer that question.

Ousterhout's dichotomy claims that there are two general categories of programming languages:

On hiring Haskellers

On hiring Haskellers

Recently I noticed the number of the same two questions being asked again and again on different Haskell resources. The questions were “How to get a Haskell job” and “Why is it so hard to find Haskellers?” Although these two are coming from the opposite sides of the hiring process, the answer is really just one. There is a single reason, a single core problem that causes difficulties of hiring and being hired in the Haskell community, and we should clearly articulate this problem if we want to increase the Haskell adoption.

We all know that there are many people wishing to get a Haskell job. And a visible increase of Haskell jobs looks like there should be a high demand for Haskellers. The Haskell community has also grown like crazy past years. But still, why is it so difficult to hire and to be hired? Why can’t companies just hire any single person who demonstrates a deep knowledge of Haskell in blog posts, in chats, on forums, and in talks? And why do Haskell companies avoid hirin

Categories are just monads in the bicategory of spans, what's the problem?

Let's imagine how a given category is a monad in a bicategory of spans.

Consider the set of all the objects in the category C0 and the set of all the morphisms in the category C1 (they're all muddled together in this set). We have two functions domain : C1 -> C0 and codomain : C1 -> C0 which assign to each morphism its source and target object.

This pair of functions forms a "span" of sets, which is a diagram of this shape:

       C_1
      ╱   ╲
   dom     cod

╱ ╲

Diagram of every possible TypeScript type

Hasse diagram of every possible TypeScript type

  • any: magic, ill-behaved type that acts like a combination of never (the proper [bottom type]) and unknown (the proper [top type])
    • Anything except never is assignable to any, and any is assignable to anything at all.
    • Identities: any & AnyTypeExpression = any, any | AnyTypeExpression = any
    • Key TypeScript feature that allows for [gradual typing].
  • unknown: proper, well-behaved [top type]
    • Anything at all is assignable to unknown. unknown is only assignable to itself (unknown) and any.
    • Identities: unknown & AnyTypeExpression = AnyTypeExpression, unknown | AnyTypeExpression = unknown
  • Prefer over any whenever possible. Anywhere in well-typed code you're tempted to use any, you probably want unknown.
