At Stackify, we’re all about helping you improve your application’s performance. We have actually developed two code profilers ourselves. Because of that, we like to think we know a thing or two about code profiling. Today I want to talk about the three different types of code profilers, describe the differences between them, and recommend some tools for your toolbox. …
According to the 2019 StackOverFlow Developer survey, Python is the fastest growing major programming language, with 41% of software engineers using Python. With the continuing popularity of Python, choosing the best IDE (or Integrated Development Environment) is important. Development and testing is becoming increasingly complicated with multiple files and unit tests involved. Life is easier for programmers when they can …
Java agents are a special type of class which, by using the Java Instrumentation API, can intercept applications running on the JVM, modifying their bytecode. Java agents aren’t a new piece of technology. On the contrary, they’ve existed since Java 5. But even after all of this time, many developers still have misconceptions about this feature—and others don’t even know …
You may have heard of aspect-oriented programming, or AOP, before. Or maybe you haven’t heard about it but have come across it through a Google-search rabbit hole. You probably do use Spring, however. So you’re probably curious how to apply this AOP to your Spring application. In this article, I’ll show you what AOP is and break down its key …
Many things in programming sound like they should be easy, but are quite hard. Calculating elapsed time in Java is one of those. How hard could that be? As it turns out, it can be tricky. For starters, we have the fact that time itself is a tricky concept. For a quick example, remember that many places around the world …
As exciting as it can be to write new features in your ASP.Net application, our users inevitably encounter failed requests. Do you know how to troubleshoot IIS or ASP.NET errors on your servers? It can be tempting to bag on your desk and problem your annoyance. However, Windows and ASP.NET provide several different logs where failed requests are logged. This …
.NET Profilers are a developer’s best friend when it comes to optimizing application performance. They are especially critical when doing low level CPU and memory optimizations. But did you know that there are three different types of profilers? Traditional .NET profilers that track process memory usage, time spent per line of code and frequency of method calls. Lightweight profilers or other …
Have you heard the saying “you can’t manage what you can’t measure?” The phrase is often attributed to management thinker Peter Drucker, and less often to other authors as well. It can also slightly vary in its wording, depending on the source. At the end of the day, the exact wording of the sayer and who said it first doesn’t …
Debugging performance issues in production can be a pain and, in some cases, impossible without the right tools. Java profiling has been around forever, but the java profilers most developers think about are only one type: standard JVM profilers. However, using one type of profiler is not enough. Suppose you’re analyzing your application’s performance. There are multiple profiling activities which …
Monitoring an application’s performance is one of the hardest challenges in software development. That’s true for virtually any programming language and platform. Java performance monitoring presents some unique challenges of its own. For instance, one of those challenges has to do with garbage collection. Java features automatic memory management, which frees the developer from having to manually dispose of obsolete …
Equality is an essential concept when programming, not only in Java but in pretty much all programming languages. After all, much of what we do when writing code has to do with comparing values and then making decisions based on the results of such comparisons. Unfortunately, dealing with equality can often be tricky, despite being such a vital part of …
Spring Boot is an open-source micro framework maintained by a company called Pivotal. It provides Java developers with a platform to get started with an auto configurable production-grade Spring application. With it, developers can get started quickly without losing time on preparing and configuring their Spring application. This post will guide you through understanding what Spring Boot is and what …
If you’re a software developer, then you probably—every now and then—feel overwhelmed by the super-fast pace at which our industry evolves, and that’s fine. I certainly feel that way sometimes, especially when trying to keep up with the latest trends. But it’s possible to be well-informed about what’s going on out there, and use that information to your advantage, by …
Are you trying to teach yourself to code? Or are you already an experienced developer who wants to pick another language? In both cases, you know how frustrating it can be to find good tutorials online. Sure, it’s easy to find “tutorials”, but separating the chaff from the wheat is a whole different story. Of course, you have to pick …
It’s one thing to write code that works. But what about clean, readable, concise code? That’s another thing entirely. To create an app that solves one problem? Not that hard. What about one that not only solves the problem, but it’s also easy and pleasurable to use? Now we’re talking. You could apply the same reasoning for many software properties, …
Software is a complex thing. As soon as you deploy an application to production—especially when you don’t have any control over the environment it’s running on—anything could happen. You’ve created this “monster” and set if free. It’s now free from your control. How do you tame this beast before it creates havoc? The first step is to trace its steps …
You’ve already used PHP streams in your PHP development. However, they’re transparent, so you may not have noticed them. Streams are powerful tools. In this article, you’ll learn to harness the power of streams in your PHP development and take your applications to the next level. What are streams? Streams provide on-demand access to data. This means you don’t need to …
A great thing about building applications for the internet is that people from all around the world can benefit from your effort. You can gather new users from Taiwan to Colorado and meet their needs just as effectively. In this global context, it can be good to provide your users with local flavor to help them feel connected to you …
The introduction of Google Maps in 2005 changed the way we think about the internet. It’s hard to remember now, but there was a time where the internet was disconnected from the physical world. You might find a business’s website, and if you were lucky, they’d have an address included. A national chain of restaurants or grocery stores probably wouldn’t …
About a decade ago, the Ruby programming language made a big splash in the software engineering industry thanks to the Ruby on Rails web framework. The terse and friendly syntax of Ruby and the “they thought of everything” feeling of Rails offered web startups the ability to move quickly and nimbly. However, as an interpreted language, Ruby is slow compared to compiled languages. The …
