Push Notifications

Recently I was exploring a relatively new feature of modern browsers - Push Notifications. While working on HTML5, I stumbled upon a site (https://html5test.com/) which shows a detailed list of features supported by different browsers. If you open above site in IE 11, you will notice that Push Message is not supported on it.

I followed an article by Joseph Medley on Web Push Notifications. The article clearly explains Service Workers. There is a working code in Github.  Interestingly I could not open Firebase Developer Console on Chrome (44). But again, its good that we have options (Firefox).

One interesting fact about running these applications on IIS (on your laptop) is that .json files are not read properly. In such cases, navigate to the virtual directory on IIS & under MIME Type, please add another entry as shown in below image.

MIME Type
Once you add this, you will be able to enable notifications & subsequently push messages to client's system.

My next step is to explore more options for sending notifications to specific users. There are lot of third party tools for doing this task. But I am interested in building my own.

Will keep exploring...

Working with large xml files in c# .net

Working with large (huge) xml files is always a pain in the … The reason? These files can’t be loaded in to memory. On my desktop, where I have 2 gigs memory, I can’t open the file in even notepad. I was presented with a challenge recently to manipulate one such large xml file. The xml file was of 550+ MB. I know many would say I have seen bigger xml files than this. But the heart of the matter is if I can’t open 550+ MB file in notepad or in xmldocument in c#, then I can’t open any file bigger than this. And hence the logic to play with these files would remain same. The scenario: We have an xml file from which we want to remove a single node without removing its children. In the below sample xml fragment, the node has to be removed. The children nodes, must then be attached to ( node’s parent) node. One Two 100.22 GoodDay 3 4 Five 200.09 Cra...

Upgrade and Migration for SharePoint Foundation 2010

      1.1 Introduction Microsoft SharePoint Foundation 2010 has been designed for scale and performance and as such requires new hardware and software requirements. There are 3 major steps while upgrading. 1. Plan and Prepare 2. Perform a database attach upgrade 3. Verify upgrade 1.2 Plan and Prepare   Before we run any process to upgrade from Windows SharePoint Services 3.0 to Microsoft SharePoint Foundation 2010, we have to determine which upgrade approach to take. In our scenario, Database Attach Upgrade seems to be appropriate approach to follow. We can upgrade the content for the environment on a separate farm. The result is that you do not upgrade any of the services or farm settings. You can upgrade the databases in any order and upgrade several databases at the same time. While each database is being upgraded, the content in that database is not available to users. 1.2.1 Upgrade Approach A database attach upgrade enables you to move to...

Object Oriented Analysis & Design (OOAD) and Unified Modelling Language (UML)

Part 1 – Identifying Use Cases – Use Case Diagrams Recently I went through OOAD and UML training. The OOAD and UML tutorial was very impressive and I decided to share it with you. Object Oriented Analysis & Design and Unified Modelling Language is very important in a life cycle of a project. Previously I was involved in project requirement study and technical design. But this time, I learned the tricks of the trade. I discovered different tips for identifying Use Cases, Actors and Classes . In this series of posts, I am planning to take you through the process of involvement of UML in Requirement analysis and Design phase. This series will include 3 parts... Part 1. Identifying Use Cases – Use Case Diagrams Part 2. Realizing Use Cases – Sequence Diagrams Part 3. Identifying Classes – Class Diagrams For this purpose we will take commonly available sample requirement – Student Registration process. From this requirement we will identify the ACTORS and US...
