Being a UI developer, I’ve learned one thing: It doesn’t matter how carefully you write your code. Suppose you’ve double-checked that you defined and called all functions the right way or followed all the best practices. Even then you’ll see that a tiny variable can sneak behind and create an error. Now, suppose you find out that for some unknown …
Troubleshooting is a critical skill for developers and DevOps. As our software grows more sophisticated, our problems do too. The cloud adds a new layer of complexity since we need to know how to find a problem that doesn’t occur locally, but has cropped up on a remote system. In this tutorial, we’ll look at how to troubleshoot Ruby applications. …
If you use PHP or you find yourself “adopting” a PHP app (like I did a few years ago), you must know how to debug PHP.

But debugging Node.js needn’t be this hard. The more you relate to this tweet, the more you must read on. Your sanity begs you. Today we’re going beyond just …
The best-laid plans of mice and men still go off the rails sometimes. Even when you’ve been rigorous and put unit tests in place, there are times when you’ll want to jump in and debug an application or a unit test. In this article, we’ll take a look at 10 tips for .NET debugging. 1. Setting Breakpoints A breakpoint is …
Computer programmers are bombarded with jargon and terminology. Experienced programmers have learned how to work with these terms. Beginning programmers become frustrated and confused. To some degree, it’s a rite of passage in the programming world. It separates the wheat from the chaff. Troubleshooting and debugging are two concepts programmers need to learn and distinguish between. You not only need …
There is a lot of evidence to suggest that slow loading times and clunky interaction will drive customers elsewhere. Even in the case of internal applications where the users have no option but to use the application, their satisfaction is tightly coupled to speed. Therefore, ASP.NET performance is one of the most important considerations when building an ASP.NET application There …
Last week, I had an urgent request from a client that we know well. They had an IIS app pool that was experiencing frequent crashes, and they couldn’t figure out why.
