• What can I do with dynamic typing that I can not do with static typing

  - by Justin984

  I've been using python for a few days now and I think I understand the difference between dynamic and static typing. What I don't understand is why it's useful. I keep hearing about its "flexibility" but it seems like it just moves a bunch of compile time checks to runtime, which means more unit tests. This seems like an awfully big tradeoff to…

• What functionality does dynamic typing allow?

  - by Justin984

  I've been using python for a few days now and I think I understand the difference between dynamic and static typing. What I don't understand is under what circumstances it would be preferred. It is flexible and readable, but at the expense of more runtime checks and additional required unit testing. Aside from non-functional criteria like…

• Static/Dynamic vs Strong/Weak

  - by Dan Revell

  I see these terms banded around all over the place in programming and I have a vague notion of what they mean. A search shows me that such things have been asked all over stack overflow in fact. As far as I'm aware Static/Dynamic typing in languages is subtly different to Strong/Weak typing but what that difference is eludes me. Different…

• Differences between Dynamic Dispatch and Dynamic Binding

  - by Prog

  I've been looking on Google for a clear diffrentiation with examples but couldn't find any. I'm trying to understand the differences between Dynamic Dispatch and Dynamic Binding in Object Oriented languages. As far as I understand, Dynamic Dispatch is what happens when the concrete method invoked is decided at runtime, based on the…

• Dynamic Types and DynamicObject References in C#

  - by Rick Strahl

  I've been working a bit with C# custom dynamic types for several customers recently and I've seen some confusion in understanding how dynamic types are referenced. This discussion specifically centers around types that implement IDynamicMetaObjectProvider or subclass from DynamicObject as opposed to arbitrary type casts of standard…

• What is the best keyboard for typing speed (not layouts)

  - by Gapton

  So I am a programmer, and I like playing typing speed games. My typing speed is, for common English words, 85 to 90 wpm, max 95. I type on various devices, my laptop, desktop, office pc.... they all have slightly different keyboards. Being a curious programmer, I wonder what types of keyboard is used for the highest possible…

• Creating a dynamic, extensible C# Expando Object

  - by Rick Strahl

  I love dynamic functionality in a strongly typed language because it offers us the best of both worlds. In C# (or any of the main .NET languages) we now have the dynamic type that provides a host of dynamic features for the static C# language. One place where I've found dynamic to be incredibly useful is in building extensible…

• Dynamic vs Statically typed languages for websites

  - by Bradford

  Wanted to hear what others thought about this statement: I’ll contrast that with building a website. When rendering web pages, often you have very many components interacting on a web page. You have buttons over here and little widgets over there and there are dozens of them on a webpage, as well as possibly…

• How can I set up multiple dynamic users to update a single network's dynamic IP

  - by d3vid

  On my home network we are allocated a dynamic IP. I want to configure ddclient (or an equivalent) to send IP updates to DNS-O-Matic/OpenDNS only when I am on my home network. I do not want to send IP updates when I'm on my office network. Can this be done? I am prepared to use different FLOSS software or a different free…

• Is there a compiled* programming language with dynamic, maybe even weak typing?

  - by sub

  I wondered if there is a programming language which compiles to machine code/binary (not bytecode then executed by a VM, that's something completely different when considering typing) that features dynamic and/or weak typing, e.g: Think of a compiled language where: Variables don't need to be declared Variables can be…

• Which tips helped you learn touch-typing? [closed]

  - by julien

  I've been learning touch-typing for about two weeks now, and I'm really commited to mastering this skill. Eventhough I'm doing ok with prose already, I'm struggling with programming syntax and even more with keybindings. Those stray you away from the home row more than regular words, and aren't as easy to…

• Python Forgiveness vs. Permission and Duck Typing

  - by darkfeline

  In Python, I often hear that it is better to "beg forgiveness" (exception catching) instead of "ask permission" (type/condition checking). In regards to enforcing duck typing in Python, is this try: x = foo.bar except AttributeError: pass else: do(x) better or worse than if hasattr(foo,…

• Simulating aspects of static-typing in a duck-typed language

  In my current job I'm building a suite of Perl scripts that depend heavily on objects. (using Perl's bless() on a Hash to get as close to OO as possible) Now, for lack of a better way of putting this, most programmers at my company aren't very smart. Worse, they don't like reading…

• Free Dynamic DNS Nameservers

  - by Maxim Zaslavsky

  I recently set up a home server that I want to use as my primary hosting platform. So far, I've mapped some domains to it by setting up A records for them that point to my home IP. As my home IP can change randomly and without notice, however, I'm afraid of such downtime. Thus, I'm…

• Using JSON.NET for dynamic JSON parsing

  - by Rick Strahl

  With the release of ASP.NET Web API as part of .NET 4.5 and MVC 4.0, JSON.NET has effectively pushed out the .NET native serializers to become the default serializer for Web API. JSON.NET is vastly more flexible than the built in DataContractJsonSerializer or the older JavaScript…

• Can static and dynamically typed languages be seen as different tools for different types of jobs?

  - by Erik Reppen

  Yes, similar questions have been asked but always with the aim of finding out 'which one is better.' I'm asking because I came up as a dev primarily in JavaScript and don't really have any extensive experience writing in statically typed languages. In spite of this I definitely…
