A customer who is visiting your website from Google Chrome may have a different user experience than a customer who is visiting your website from Safari, Mozilla Firefox, or any other browser. But wait, there is more! Rendering engines not only differ from one browser to another, but they also differ from one browser version to another. Meaning, Google Chrome 72 may render a website differently than Google Chrome 65.

After yesterday’s post , someone on Twitter expressed concern about providing a “degraded experience” to users who have Save-Data enabled. It’s far from the first time I’ve heard this concern expressed. A user sees “Save Data” as an option and says, “Yeah, of course!” but they may not want a lesser experience as a result.

Running speed tests with tools like Google PageSpeed Insights , WebPageTest , or KeyCDN’s Website Speed Test are always a good way to help gauge your website’s performance. While these metrics can be very helpful it is also important to keep this data in perspective. While they can provide valuable information to help optimize your website, don’t forget about perceived performance, specifically the user’s experience.

The changes we made affected both how we built applications and how we organized our company.

Most teams find it hard to “do DevOps” in the DB for several reasons. This talk summarizes what I’ve learned over the last decade, studying teams that succeeded as well as those that tried. I’ve distilled it all into concrete, practical steps you can take to improve. Databases are special because they’re stateful, and DevOps reflects this: in practice, databases are a lot harder to “DevOps” (as a verb) than other parts of the stack.

In this era, every organization is on the path of test automation to increase efficiency. Just like manual testing, automation testing also needs proper planning, structure, monitoring, and maintenance. Test cases can be defined as a set of conditions wherein a tester determines whether an application/software system or one of its features is working as expected or not.

Often times when you are processing data through a flow, you may want to treat certain errors differently than others. For instance, if you are trying to select records from Salesforce , you would want to handle a record not found error differently than an out of memory error. For this reason, MuleSoft allows us to handle errors based on use cases as well as the types of errors that are being thrown.

Thanks to projects such as OpenTelemetry , which promotes the standardization of data collection, and W3C trace-context , built-in telemetry will soon become a must-have feature of cloud-native software.

This is the second generation EPYC server processor that uses the same Zen 2 architecture as the AMD Ryzen 3000 Series desktop processors. These new processors are socket compatible with the previous generation AMD EPYC 7001 Series processors, so they will work in existing model servers (with a BIOS update).
