Over the past few weeks, I’ve been working on making a legacy web application more accessible. Key factors in accessibility are being keyboard and narrator friendly. These factors are governed by various “A11yMAS” guidelines. For this post, I’ll focus on a particular AngularJS datatimepicker (calendar) directive, which is used in the legacy web application, that lacked keyboard accessibility completely.

Rendering String Images and Barcodes
posted on September 13, 2017 by long2know in css, MVC
In one of my current projects, I needed to render some barcodes. Google has a nice “Code 128” barcode font which makes rendering a barcode in a website pretty easy. However, in this particular application, I wound up needing to render the barcodes as images since the HTML that I render is fed into a PDF creator that doesn’t support font-face CSS stylings.
Moving from OWIN to .NET Core
posted on April 23, 2017 by long2know in ASP.NET, OWIN, Web
Since the OAuth server I’ve detailed previously is using OWIN, I’ve been looking at what it will take to move it to .NET Core. The OWIN OAuth Server provides all of the Secure Token creation. This functionality is not provided with .NET Core’s native middleware.
My first thought is to integrate with IdentityServer4 or Openiddict which provide Secure Token generation and are .NET Core compatible. After some cursory information gathering, I’m putting a few research links here for later use.

Free SSL Certs
posted on March 6, 2017 by long2know in Web
Long, long ago, I wrote about StartSSL. It was actually one of my first blog posts. After using the StartSSL (StartCom) service without issue for over two years, it appears that their root authority has been revoked making their free service virtually useless. I had to find an alternative.
Angular links of interest
posted on July 5, 2016 by long2know in angular, JavaScript, react, redux, Web
I’ve been reading up on Angular2, Redux, React and other various libraries and frameworks over the weekend.
I’m in the process of understanding what using Redux w/ an Angular2 app provides that using a singleton service doesn’t. But, it seems to be more about preference (imho) than real-world benefit. It may help tie into observable / push notifications to make state change detection between immutable / mutable objects more performant. However, I can see a benefit if one wants to swap out frameworks and allow their previous state management work across frameworks. It’s an interesting prospect from that perspective.
Creating Visual Studio Templates Part 1
posted on April 24, 2016 by long2know in ASP.NET, Microsoft, Web
I have amassed a lot of code. When I’m creating a new web application, this is handy because it provides me with a good basis. However, I’ve never gone to the trouble of wrapping all of this into a template to eliminate the redundancy.
Service Pattern for accessing an external Api
posted on February 5, 2016 by long2know in ASP.NET, Web
A friend of mine asked me earlier today what a good pattern for accessing an Api from within a class library would look like. In .NET, I generally like to wrap this type of functionality within a service that can be injected.
Bringing older HTML up to HTML5 standards
posted on January 29, 2016 by long2know in css, Web
In my last post, I discussed some observations that I made regarding maintaining legacy web-sites. Although, afaik, all of the information I presented in that post is accurate, if you want to bring your old quirks/compatibility-view reliant page up to modern HTML5 standards, here are some tips.
Maintaining legacy web sites
posted on January 24, 2016 by long2know in Web
Over the weekend, I had an interesting experience updating an old, legacy website that uses ASP. ASP is interesting, but the more interesting thing is that many of these old applications rely on specific browser modes or default to “quirks” mode.
Another weird IE11 rendering bug

While testing a new application that utilizes my multiselect drop-down widget, I noticed some weird behavior with IE11.
