Optimizing your images is often the very first suggestion that any performance writer or consultant will make when it comes to optimizing a website. We’re no exception. Make no mistake, this is a key step to take and should absolutely be a part of your web design/development routine. However, what do you do when you optimize your images and still don’t see a noticeable improvement in the performance of your site?
Is Internet Explorer.irrelevant? A question that has been on the back of minds for many web developers and testers who are involved in cross-browser testing. “Does Browser Testing On Internet Explorer Still Make Sense?”. We are into 2020 and it has been more than 6 years since Internet Explorer last received an upgrade from Microsoft. On 1/12/2016, Microsoft ended support for IE10 and older versions.
Automation is cool. You simply choose the best tool, create test scripts for your smoke test suite and regression test suite, and click the "run" button. Then you get to sit back and watch stuff zip around the screen. The benefit: Testers get to spend time doing exploratory testing or partake in other valuable testing pursuits because their routine testing now takes minutes, right?
Dynatrace news. In part one, we began our discussion about intellectual debt by pointing out how machine learning systems contribute to the widening gap between what works and our understanding of why it works. Part two added a few simple examples of how intellectual debt might accrue, highlighting the subtle but real drag on efficiency. We concluded by suggesting that the fuzziness of machine learning systems presents a fundamental problem for autonomous IT operations.
Until recently, manual traceability from compliance reporting has held back large organizations from becoming software innovators. Now, enterprise toolchain integration is helping organizations across heavily-regulated industries, such as healthcare, automobile, finance and government, to automate the sophisticated flow of work from ideation to operation, helping them obtain one source of truth into a product’s development.

Make sure you stay covered! Test Coverage and Code coverage are the most popular methodologies for measuring the effectiveness of the code. Though these terms are sometimes used interchangeably since their underlying principles are the same. But they are not as similar as you may think. Many times, I have noticed the testing team and development team being confused over the use of these two terminologies.
Some may see testing as a fairly boring and static set of practices, but leaders in this space know it is a vibrant discipline that is constantly improving every year, thanks to exciting new techniques made possible by better automation tools and artificial intelligence. More than ever, software quality drives business growth. Attending conferences is the best way to keep your skills and knowledge about these trends up to date and connect with your peers in the larger testing community.
Dynatrace news. As the owner of a ride-hailing company, for example, you might have questions like “How many active drivers do we have per region?”, “What’s their average ride distance?”, or “Which are the most popular destinations?” Also, you’d probably like to be alerted of significant anomalies. In an existing application landscape, however, it can be difficult to get to those metrics.
In this article, we will discuss the best practices that should be followed in order to keep the TempDB database in a healthy state and prevent any unexpected growth of the database, in addition to the procedure that can be followed to detect this unexpected growth once occurred. TempDB overview The TempDB database is one […].
Avoid these pitfalls of scaling VoIP to cluster. VoIP technologies have a reputation for being rather complex and not without good reason. This is not to say, however, that any mid-level developer will have much difficulty finding and handling one of many available open-source servers. The only problem is the lack of information and real-world examples, as VoIP server homepages rarely have configurations that go beyond the very simplest option, and even when they do, they may be not up-to-date.

Learn how to conduct effective unit tests. First of all, I will start with a disclaimer that I am a strong proponent of using the simple factory programming idiom and by extension of using the Factory Method Pattern , instead of creating objects inside classes. The factory idiom helps you to insulate your code to changes thereby adhering to the Open to Extension Close to modification principle of object-oriented programming.
Six months ago I wrote about the Bounded Context Canvas. In the six months since I’ve received feedback from my own workshops and other people’s workshops about ways to improve the canvas. Here is V2 of the canvas. Please feel free to use it, create remixes, or simply take it as inspiration to develop your own ways of designing bounded contexts. Whatever you do, I’d love to hear about it?

“If you measure anything, measure wait time” – Dominica DeGrandis, Making Work Visible. A major part of Flow Metrics is tracking all the work that goes into planning, building and delivering a product for the business. Just as it’s important to track how much value you’re delivering, how long work is takin, and how much WIP your teams have, it’s also vital to track what work is actively (code, test, automation, designing and all that creative work) being worked on to identify where waste a

Programmatically interpretable reinforcement learning , Verma et al., ICML 2018. Being able to trust (interpret, verify) a controller learned through reinforcement learning (RL) is one of the key challenges for real-world deployments of RL that we looked at earlier this week. It’s also an essential requirement for agents in human-machine collaborations (i.e, all deployments at some level) as we saw last week.
Find out more about client-side performance! Client-Side Performance Testing Importance and Introduction. If you're worried about the performance of your web application, you need to test and analyze not only with what happens on the server but also with what happens in the browser. Some commercial performance-monitoring solutions already take this into account, allowing performance engineers to see how long it takes for elements to render, and then to execute, on your users' browsers.
In this article, we will discuss the most important points that we should consider when designing an optimal SQL index.
