Back in my C++ days, I knew most of the ins and outs of make, and makefiles and sub-makefiles. I could do pretty much whatever I needed to. Of course, in complicated projects the files start looking really ugly inside. Then for Java there was ant, which tidied up all the targets and dependencies in structured […]

Sometimes I wonder whether I can still hack it in this industry. Like many people of my vintage, my programming language progression was Fortran, Cobol, Basic, Pascal, Unix shell script, C++, Java, Javascript and Python. I stopped there. So I did not learn Go, Rust, Erlang, Scala, Kotlin, Node or Typescript and while I’ve started […]

One of my team members is retiring, and as we were talking about their tenure with the company, “We did a LOT!” they said. That got me looking back at the past 2 years, and I started listing some of the changes and accomplishments that happened, first while I was leading the engineering team as […]

When people think of DevOps, they likely think of delivery of code into production. Microsoft, Amazon and DevOps.com all mention delivery in the first paragraph of their definitions of DevOps. However, code has to be developed and tested before it can be shipped. That requires an environment where developers can integrate their code, an environment where QA teams can perform […]

The solution had to work if the origin VPCs were in different AWS accounts. Part I: NAT Gateway I took it in stages. I first […]

As a Mac user with concerns about privacy and data security, I have used a personal firewall on my laptop for many years. The specific one I use is Little Snitch. Normally I don’t name products but I like it so much that I have no problem making this exception. The way it works is […]
Recently I had to dive into Android app development to fix an issue in an app. Then, while I was testing the app I noticed that the payment process was not working. The app uses Instamojo, a payment gateway provider in India. The process works fine through the Web client, but the Android flow was broken. […]

We had a member of the Central Information Commission present to “launch” the site and talk about the importance of the Right to Information [known in other countries […]

In a previous article, I showed how to set up a web application to use microservices with just the bare minimum of effort. However, that can result in some limitations, such as the presentation layer (or API Gateway) that aggregates the results of the microservices using hard-coded endpoint addresses (e.g. http://localhost:8888/api/v1/fromurl). In actual practice, this […]
