Dynatrace news. While not a new concept, the term “cloud” creates a lot of confusion because it means different things to different audiences. I’ve been speaking to customers over the last few months about our new cloud architecture for Synthetic testing locations and their confusion is clear. Hearing things like “Will you have more than one geographic location?
Performance testing and engineering is always a niche area with many challenging objectives across the globe. The challenge of performance testing with performance engineering is far more complex and requires one to be multi-skilled to find problems/issues/defects. In the last few years, I have come across several interviews, discussions with client-facing groups and customers, and what they have in common is a high demand for performance engineers, not just performance testers.
The infotainment and entertainment industry has undergone a phenomenal change with online channels and providing features such as movies and other content on demand. Similarly, The post Continuous Testing in Software Development can Ensure Excellence in Quality appeared first on Kovair Blog.

Quality assurance (QA) testing is an essential part of the software development process, involving the identification of bugs in products to ensure they are as error-free as possible. Unfortunately, there are also a lot of misconceptions about what QA testing and QA services actually entail. Today, many companies engage in software QA outsourcing , sometimes using offshore testing services, while some still keep their QA services in-house.
A few months ago, I wrote the post " Amazon Aurora ascendant: How we designed acloud-native relational database ," and now I'm excited to share some news about the people behind the service.

Today I collated and analyzed the results of the survey I posted two weeks ago. I presented you with a daunting unsorted list of ~300 eye-numbing paper titles , and still 289 of you responded with ~1,200 total votes (not everyone picked five things) many of which contained thoughtful “how I would use it” verbatims. Thank you for your time and interest!

I hope to raise the profile of difficulties faced by real people, which are avoidable if we design and develop in a way that is sympathetic to their needs.
There are tons of tools out there that help you make sure your app is functioning correctly. But how do test software from a purely visual standpoint? Chances are you’re writing functional tests to check visual elements, or manually checking your UI whenever you push a change. If you are doing either of those things, then you know that they’re incredibly time-consuming and bugs still end up slipping through the cracks.
Software engineering for machine learning: a case study Amershi et al., ICSE’19. Previously on The Morning Paper we’ve looked at the spread of machine learning through Facebook and Google and some of the lessons learned together with processes and tools to address the challenges arising. Today it’s the turn of Microsoft. More specifically, we’ll be looking at the results of an internal study with over 500 participants designed to figure out how product development and software engineering

Meta-learning neural bloom filters Rae et al., ICML’19. Bloom filters are wonderful things, enabling us to quickly ask whether a given set could possibly contain a certain value.

It’s no wonder Bloom filters and their derivatives (the family of approximate set membership algorithms) are used everywhere.
WG21 has a strict schedule (see P1000 ) by which we ship the standard every three years. We don’t delay it. Around this time of each cycle, we regularly get questions about “but why so strict?”, especially because we have many new committee members who aren’t as familiar with our history and the reasons why we do things this way now. And so, on the pre-Cologne admin telecon last Friday, several of the chairs encouraged me to write down the reasons why we do it this way, and some of the history b
