For the longest time, hosting static files on CDNs was the de facto standard for performance tuning website pages. The host offered browser caching advantages, better stability, and storage on fast edge servers across strategic geolocations. Not only did it have performance benefits, but it was also convenient for developers. Recent developments, however, show that self-hosting static files such as Ajax (Asynchronous JavaScript and XML) and jQuery libraries, CSS styles, and other include directi

A significant feature of Chronicle Queue Enterprise is support for TCP replication across multiple servers to ensure the high availability of application infrastructure. I have generally held the view that replicating data to a secondary system is faster than sync-ing to disk, assuming the round trip network delay wasn’t high due to quality networks and co-located redundant servers.

Humans are notoriously poor at judging distances. There’s a tendency to underestimate, whether it’s the distance along a straight road with a clear run to the horizon or the distance across a valley. When ascending toward a summit, estimation is further confounded by false summits. What you thought was your goal and end point turns out to be a lower peak or simply a contour that, from lower down, looked like a peak.

The Failed Auto-Params/sec counter is incremented when decoding fails and the statement is not parameterized.

One of the benefits of being an agile organization is the elimination of IT shadows: the functions and activities that crop up in response to the inadequacy of the plans, competency and capacity of captive IT. IT shadows appear in a lot of different forms. There are shadow IT teams of developers or data engineers that spring up in areas like operations or marketing because the captive IT function is slow, if not outright incapable, of responding to internal customer demand.

A challenge that many developers face in Selenium test automation is choosing the right test framework that can help them come up with automated tests with minimal (or no) requirement of boilerplate code. Like me, most of you would have come across test code where a huge chunk of code is written to perform a simple test. The selection of the right test automation framework can greatly simplify the job of the developer working on the test code.

Testing is often viewed as a necessary evil in software development, in order to ensure the quality of applications. Most commonly, however, testing occurs after the coding process has been completed. However, according to the Ministry of Testing’s OpsBoss and author of Testing of Web APIs Mark Winteringham, testing should apply across the entire software development lifecycle.

Interestingly, our partner RedHat reported in 2021 that around 80% of deployed workloads are databases or data caches, storing data in persistent volume claims (PVCs). Famous examples include Redis , PostgreSQL , MySQL, and MongoDB.

If you’ve used Prometheus in the past for metrics collection/monitoring, then you’re probably familiar with Prometheus recording rules. As the Prometheus documentation says, recording rules allow you to precompute frequently needed or computationally expensive expressions and save their result as a new set of time series. Recording rules are the go-to approach for speeding up the performance of queries that take too long to return, and they are also commonly used to alias complex or repetitive P
