PostgreSQL replication comes in two forms, and both have their niche uses. Understanding how to apply one or both of these data replication methods can […].
Experimentation tools that use asynchronous scripts – such as Google Optimize, Adobe Target, and Visual Web Optimizer – recommend using an anti-flicker snippet to hide the page until they've finished executing. But this practice comes with some performance measurement pitfalls: Hiding the contents of the page can have a dramatic effect on the Web Vitals that measure visual experience, such as First Contentful Paint (FCP) and Largest Contentful Paint (LCP).

Recently, I was introduced to a new islands challenge by my friend Erland Sommarskog. It’s based on a question from a public database forum. The challenge itself isn’t complicated to handle when using well-known techniques, which primarily employ window functions. However, these techniques require explicit sorting despite the presence of a supporting index.

Recently, I faced an issue related to a very high load on the database layer. The database was having too many connections in parallel. I had to review my application’s database connection pool (DBCP) properties very closely. Since I was dealing with legacy code, I needed to understand the value assigned to each property and also analyze whether it is relevant for the present-day load or not.

A while ago I helped a colleague, Vadim, debug a performance issue with TensorFlow in an unexpected location. I thought this was a bit interesting so I've been meaning to share it; here's a rough post of the details. ## 1. The Expert's Eye Vadim had spotted something unusual in this CPU flamegraph (redacted); do you see it?: I'm impressed he found it so quickly, but then if you look at enough flame graphs the smaller unusual patterns start to jump out.
A common theme among most software testing organizations is their escalating interest in Test Automation. While test automation has grown in popularity, there are still many myths and biases surrounding it. Such myths can unknowingly create a self-limiting boundary and negatively impact the possibilities of test automation. In this article, I will discuss some common test automation myths and biases that people have towards test automation.
Introduction. The Internet is inevitable in the current time. It is everywhere, and the entire world depends on it to function, perform day-to-day activities and stay connected with people from different corners. Gone are the days when testers only chose to create websites for selected browsers and hardly faced issues maintaining a website on a few browsers.
Dynatrace news. The continued growth of e-commerce has led to digital transformation moving at unprecedented speeds, as retailers compete for the attention of over 2.1 billion online shoppers. But as online stores have expanded, they’ve become more complex, and so has the technology underpinning them. The rise of cloud complexity. Retailers are increasingly adopting multicloud strategies to gain the agility required to succeed.
In my last article , we went over how to set up a web app that serves chunks and bundles of CSS and JavaScript from CloudFront. We integrated it into Vite so that when the app runs in a browser, the assets requested from the app’s root HTML file would pull from CloudFront as the CDN. While CloudFront’s edge caching does offer benefits, serving your app’s resources from these multiple locations is not without a cost of its own.

With software requirements changing at lightning speed in an agile environment, more and more organizations look to inculcate more atomic development cycles for accelerating their Time To Market (TTM). A 2021 study by digital.ai has discovered that 86% of software development teams have adopted agile, up from 37%, a year ago. This shift to more agile software development methods has led to a simultaneous demand for more efficient means of software testing during the software is developed.
Dynatrace news. As more organizations turn to application containerization, managing the tasks and processes that come with containers becomes critical. Kubernetes helps organizations better manage containerized workloads and services. In turn, it sets the stage for fast, functional, and reliable software development. However, at scale, these deployments can encounter a common roadblock: complexity.
If you’ve been keeping up with my series of tutorials around.NET Core and MongoDB, you’ll likely remember that we explored using the Find operator to query for documents as well as an aggregation pipeline. Neither of these previously explored subjects are too difficult, but depending on what you’re trying to accomplish, they could be a little messy.
Photo by Andrew Neel There was a time where most software was built under the waterfall model. You gathered requirements, then designed your system, then wrote the code, shipped the code to QA, then shipped the code to customers. A nice perfect assembly line. Except software development isn’t an assembly line. When you get a physical product off an assembly line, you can’t just go “oh this would be perfect if we make this small change here in the product.
To start with, there has always been an inclusive and exclusive relationship between Agile and DevOps. Both are principal methodologies in the software engineering ecosystem and are known for transforming business processes through speed, iterations, and collaborations.

Execution Plans. It’s more complicated than you might expect to tell from the information provided in execution plans if a SQL statement uses simple parameterization. It’s no surprise even highly experienced SQL Server users tend to get this wrong, given the contradictory information often supplied to us. Let’s look at some examples using the Stack Overflow 2010 database on SQL Server 2019 CU 14, with database compatibility set to 150.
Introduction to Rest Assured Library. REST (Representational State Transfer) is an architecture that consumes HTTP calls for inter-system communication where a client can access the server resource with a unique URI, and the response of the resource is returned. The URI of the resource acts as a resource identifier, and HTTP operations like GET, POST, PUT, PATCH, and DELETE can be performed on the resource.
Dynatrace news. Fast, consistent application delivery creates a positive user experience that can ultimately drive customer loyalty and improve business metrics like conversion rate and user retention. Digital experience monitoring (DEM) allows an organization to optimize customer experiences by taking into account the context surrounding digital experience metrics.
I wrote some time ago that labor is enjoying a moment. New working habits developed out of need during the pandemic that in many ways increased quality of life for knowledge workers. Meanwhile, an expansion of job openings and a contraction in the labor participation rate created a supply-demand imbalance that favored labor. There appears to be confusion of late as to how to read labor market dynamics.

In the second part of this series, I described the structural hierarchy of the transaction log. As this post is chiefly concerned with the Virtual Log Files (VLFs) I described, I recommend you read the second part before continuing. When all is well, the transaction log will endlessly loop, reusing the existing VLFs. This behavior is what I call the circular nature of the log.
Renaming files is something that occurs frequently, and in Linux on the terminal, there are many ways to rename files. Let's look at some of the main ways you can rename your files on Linux and other Unix-based systems like MacOS. Renaming Files With the MV Command The mv command moves a file to another place. It can also be used to move a file to the same location, and simply change its name.
Dynatrace news. While applications are built using a variety of technologies and frameworks, there is one thing they usually have in common: the data they work with must be stored in databases.
