Understanding Graphs and Their Application on Software Systems

Lately, I wanted to spend a little bit time on going back to fundamental computer science concepts. Hopefully, I will be able to write about these while I am looking into them in order to offload the knowledge from my brain to the magic hands of the Web :) I am going to start with Graphs, specifically Depth First Traversal (a.k.a. Depth First Search or DFS) and Breadth First Traversal (a.k.a Breadth First Search or BFS). However, this post is only about the definition of Graph and its applica...

Here is My Proudest Achievement, What is Yours?

It's very common that you get asked about your proudest achievement. I wanted to put mine here publicly so that I would have a place to direct people to. So, here it is :)

My proudest achievement to this day dates back to 2010. I was working at a local Travel Agency in Turkey while still studying Travel Management at the university and we had a Web site for our customers to book their airport transfers from/to their hotels by paying online. However, the application didn't allow our customers...

Defining What Good Looks Like for a Software Engineer

If you are a software engineer, this is a very common question you will get to ask yourself a lot. This is going to be especially very frequent if you are being part of the recruitment process in your company. As you may know, I work at Redgate, and we have a good culture for development teams. Besides that, common characteristics of a good engineer with examples and counter examples for each engineering role are defined, too. This is a really good guidance for the employer to reflect their c...

ASP.NET Core Authentication in a Load Balanced Environment with HAProxy and Redis

Token based authentication is a fairly common way of authenticating a user for an HTTP application. ASP.NET and its frameworks had support for implementing this out of the box without much effort with different type of authentication approaches such as cookie based authentication, bearer token authentication, etc. ASP.NET Core is a no exception to this and it got even better (which we will see in a while).

However, handling this in a load balanced environment has always involved extra caring...

React with Redux: A Stable, Powerful and Scalable Combination - Part 1

For the last a few months, I have been using React and Redux. I successfully converted a small application from Aurelia to React + Redux combination. Actually, it's a lie that that application is small. I told you it's small because it was less than halfway done at the time I started converting. That Web application is meant to be complex and has complicated data needs. Besides that application, we started building a completely new web application on top of React and Redux: SQL Clone Web Clie...

Long-Running Asynchronous Operations, Displaying Their Events and Progress on Clients

With today's modern applications, we end up with lots of asynchronous operations happening and we somehow have to let the user know what is happening. This, of course, depends on the requirements and business needs.

Let's look at the Amazon case. When you buy something on Amazon, Amazon tells you that your order has been taken. However, it doesn't really mean that you have actually purchased it as the process of taking the payment has not been kicked off yet. The payment process probably goes...
