Symbol Hound - The search for devs.

During the course of the last week myself and a college came across an exception in our logs. The exception was from JSON.Net complaining of an unexpected character in the JSON string.  The character in question was the ^@ symbol.  A Google search for this symbol shows up very unhelpful results, you could try Carrot @ or Carrot At.

We went looking for ways to search for symbols in Google, in our searches we came across http://symbolhound.com a search engine for developers. It doesn't ignore symbols so a search for ^@ yields much more useful results and reveals that its a null character. It's a useful tool for debugging and development questions, you can even set it as one of the search options in Firefox.

Testing functions that use local storage with Jest

Testing functions that use the browsers local storage API seems easy when you know how. Here's a quick run down on how to mock it out with Jest if, like me, you're not familiar with how to test it. In the end it's very little code. Consider the following TypeScript code. import { get, save, key } from "./storage"; describe(save, () => { let setItem: jest.Mock; beforeEach(() => { setItem = jest.fn(); Storage.prototype.setItem = setItem; }); it("should call set item with predefined key and json object", () => { const valueToStore = { value: "toStore" }; save(valueToStore); expect(setItem).toHaveBeenCalledWith(key, JSON.stringify(valueToStore)); }); }); The key lines are in the beforeEach call where the setItem function of the Storage prototype is assigned to an instance of jest.fn() . This allows us to make assertions on what is passed to the local storage setItem API.

Solving `Empty reply from server` in DotNet Core

tldr; If you’re getting  curl: (52) Empty reply from server  check that you’ve configured Kestrel correctly. Long version I’ve started playing with Dotnet Core and Docker and have had a few issues getting started. I’ve had a little bit of experience with Docker, though only a little. I’ve worked with DotNet previously but never with Core. Environment The setup I’m using is a Windows laptop running Vagrant. Via Vagrant I’m running an Ubuntu Virtual Machine with the Docker run time installed. Feels a litle like inception. Key Problem The key problem that I’ve had getting started was having my Docker container not responding correctly to my curl commands. I get this: curl: (56) Recv failure: Connection reset by peer curl: (52) Empty reply from server Given that I’m not all that familliar with Docker or Dotnet Core I decided to remove one of the variables and set up a simple Express app in a different docker container. This validated that the commmand I was usin...

Can't resolve DNS Aws

Image
I recently registered a domain for a joke website  saladsimulator.com .  I figured I could whip up the page in a couple of minutes and throw it up on AWS using S3 static site hosting.  All done in an hour or so. What I thought would take an hour ended up in a multi-day ordeal while I tried to get the DNS to resolve.  I went through what seem to be the typical problems. The bucket wasn't configured to be accessible as a website. My bucket wasn't named the same as the website; the bucket needed to be saladsimulator.com to match the domain saladsimulator.com . I got these fixed up and found that it still wasn't working.  I added extra routes in to see if I could Alias or CNAME to a known working site, but they didn't work either. So it seemed it was a problem with something to do with the DNS configuration. After searching around I found a mention in a thread that the name server records in the hosted zone needed to match those in the domain name registrat...
