(JS) Regular Expression to replace "require" statements with "import statements"

Having dabbled a bit with React / Redux, and while doing so used both the Import statement from ES6 and the Require function of Browserify, I decided I needed a RegEx to replace all "require" lines to "import" lines.This is what I came up wit, so far:const\s+(\w+)\s+=\s+req... replace with;import $1 from '$2'; ......

Clever reqruitment

I was surfing the web, when I saw a small box that caught my eye: "developer, solve this". In hind sight, I guess it was an ad. I thought it was real content, though, at first.So I clicked the link and got to a page which offered a programming "riddle".Well, I solved the riddle (simply used LINQPad), and the answer was a URL. Went there, and found out ......

WebAPI Exception Logging

Comments (1) | Share

Just found out - very easily - a simple way to add logging (via log4net) to my .Net Web API. Thanks to a "code friendly" post.The whole article is full of useful information, though in this instance I focused on global logging alone.This was accomplished (again, easily) by adding the following to global.asax.cs at app-start or a function called from ......

Automated development environment

Over the past couple of months I've added more and more customization to my development machine. So much so, that I'd like to write down what I did in case I'll need to re-implement it - and maybe also help some others who might be interested.

A bit more about Using Ninject 2.2 - factory methods

Comments | Share

(Credit: Image used is from http://fav.me/d2pz3om, if the author objects, I'll remove it immedietly)As I understand it, Ninject 2.3 will have a .Bind<T>().ToFactory() Method. In the mean time, though, what do we do when we need to bind at run time? Let's say we have a Ninja class, which we want to send off to... well, 'off' someone. The problem ......

A short summary about DI and using Ninject not as a Service Locator

Comments (2) | Share

Note: This post was edited on 21st December 2011, after the first comment was left by Remo Gloor .Using Ninject in a classic DI scenario, means that only the entry point of you code should have knowledge about Ninject. This is different than using it as a Service Locator, where either all classes know about the IoC Container (Ninject, in this case) ......

IoC Container != DI

Comments | Share

Well, after reading the following article, I figured the case Paul Hiles makes is not bad. Not every one wants or needs DI, and granted, in many cases moving from a "IoC Container used as a Service Locator" solution to a "real dependency injection" solution might just be not worth it, I believe that it's a better structure, especially if you're writing ......
