Reading time 4 min People all over the world consume data on a daily basis across a variety of networks, geographies, and devices. You’ve probably lost track of how many applications are on your phone or tablet – applications for shopping, ordering food, checking the weather, reading the news, tracking the stock market, and sharing images, videos, and other content with friends and family (and maybe a few strangers).

AWS is the #1 cloud provider for open-source database hosting, and the go-to cloud for MySQL deployments. As organizations continue to migrate to the cloud, it’s important to get in front of performance issues, such as high latency, low throughput, and replication lag with higher distances between your users and cloud infrastructure. While many AWS users default to their managed database solution, Amazon RDS, there are alternatives available that can improve your MySQL performance on AWS through

The other day I was listening to the latest Shop Talk Show podcast while out for my morning run. They had Jen Simmons on the show, talking about (among other things) the standards process. It’s a great conversation, as you would expect—Jen’s super smart and has been doing great, meaningful work for a long time. Among the things that she discussed is the care that has to go into new browser features because once shipped, it’s there for good.

Dynatrace news. Threads enable your application to execute multiple tasks at the same time. This is why threads are often the source of scalability as well as performance issues. If your system is under high load, it can run into thread-locking issues that prevent upward linear scaling of your application. Another potential issue is that too many active threads waste CPU resources, either by over-utilization or by forcing the OS to schedule thousands of threads on a limited set of cores.

I seem to have a habit of writing about super powerful machines whose many cores are laid low by misuse of locks. So. Yeah. It’s that again. But this one seems particularly impressive.

We learn about HTML, we make sure things are semantic and — voila! @— we have an accessible website. During the course of conversation, someone mentioned the Domino's pizza legal case , which is perhaps the most public example of a company being sued because of a lack of accessibility.

A typical manual QA tester spends more than 50% of the time in testing the functionality of the application. A majority of time is spent in executing the same test cases multiple times for regression testing. If these repeatedly executed test cases can be automated, a lot of time and manual effort can be saved. What is Functional Testing? Functional Testing is concerned with verifying the functionality of all the features of an application under test(AUT).
