Cryptography fascinates me. It’s amazing how critical cryptography is to the internet and the digital economy. Even more amazing to me is how simple it is to crack if it’s insecure. I don’t have a computer science degree; I took some courses on algorithmic design in college, but felt so totally lost and overwhelmed that […]

For some time at SoFi, we’ve worked with Spring Batch to provide a third-party integration with a service without a robust API, but that loves to work in terms of batch files. There are a number of ways to deal with that, and we’ve taken a few different approaches. One of them is to implement […]

The stack I work in every day uses Hibernate and Spring Data JPA for its object/relational mapping framework. My company is hardly alone in using these tools to map data from a database into Java objects. They’re quite commonly used, and also quite powerful. One of the nifty features of Hibernate is Filtering. You can […]

If you’ve ever enjoyed the wonderful experience that is consuming a web service that’s at least 10 years old, odds are you’ve dealt with WS-Security headers. If you’ve had to deal with that while developing in .NET Core, you probably have spent a great deal of time banging your head against the wall. I had […]

In a previous post, I gave the arguments for and against using the JNDI for managing application configuration and attempted to contrast those arguments with using spring framework to pull in configurations from flat files. In this post, I would like to show how I managed to take an application that was heavily dependent upon […]

I don’t know if this is a debate at all, but it has been in my workplace. When managing configuration for Java EE / Spring Framework applications in a Wildfly server environment, what is better: managing an application’s configurable values at the server and environment level through the JNDI, or managing them through the use […]

Over the last few weeks, I have been focused on improving automated deployment for java web applications using Jenkins. In particular, much of the focus has been on doing so by using the pipeline plugin. This is a pretty great tool because it allows for automated deployment in a scripted fashion. If there’s one thing […]

So, I’m working on a front-end widget in asp.net mvc wherein a user is supposed to be able to upload a spreadsheet to the application I’m working on. The requirements as to the submission method for this particular form were that end users needed to be able to submit it by dragging and dropping, or […]

Stay in web development long enough, and eventually you’re going to need to do development work over an SSL connection. Because development work in SSL is typically done on localhost (like most development), you will need a certificate that certifies that localhost is secure. If you don’t, your browser will try to prevent you from […]

This morning I improved this theme by adding a filter to WordPress’s ‘the_permalink’ filter. The idea was to scan post content, pull out the first link in a post and then use that link as the permalink, so to speak. By doing this, I make it so that I can simply point my readers to […]
