Character collations determine the sort order and classification of characters. When creating a database with initdb, PostgreSQL normally sets the collation based on the operating system’s locale settings, but other special collations, such as “C,” “POSIX,” and “ucs_basic,” are available as alternatives. On Linux systems, updates to glibc can bring changes to collation rules.

Over the years, many of us have become accustomed to letting computers do our thinking for us. “That’s what the computer says” is a refrain in many bad customer service interactions. “That’s what the data says” is a variation—“the data” doesn’t say much if you don’t know how it was collected and how the data analysis was performed. “That’s what GPS says”—well, GPS is usually right, but I have seen GPS systems tell me to go the wrong way down a one-way street.

Performance and error optimization is complicated, and the approach to driving improvement has long relied on static recommendations disconnected from a site’s end users and their experiences. While traditional methods can help you understand when your users face poor performance or errors, understanding if and how much these problems impact your business remains largely guesswork.
Technology Performance Pulse brings together the best content for technology performance professionals from the widest variety of industry thought leaders.

Istio is the most popular service mesh, but the DevOps and SREs community constantly complain about its performance. Istio Ambient is a sidecar-less approach by the Istio committee (majorly driven by SOLO.io) to improve performance. Since there are many promotions about Ambient mesh being production-ready, many of our prospects and enterprises are generally eager to try or migrate to Ambient mesh.

Modern observability and security require comprehensive access to your hosts, processes, services, and applications to monitor system performance, conduct live debugging, and ensure application security protection. This level of access enables advanced capabilities such as runtime instrumentation and detailed diagnostics. While these techniques are powerful, they can pose risks if not managed properly, as demonstrated in the recent incident.

Our company uses artificial intelligence (AI) and machine learning to streamline the comparison and purchasing process for car insurance and car loans. As our data grew, we had problems with AWS Redshift which was slow and expensive. Changing to ClickHouse made our query performance faster and greatly cut our costs. But this also caused storage challenges like disk failures and data recovery.

The software landscape has undergone a profound transformation over the past two decades. In the past, a substantial portion of software was designed for local desktop use. However, today, the norm for computer users is to access web-based software services through a web browser. With the prevalence of web-based software, the paradigm has changed. We, as users, have our data residing on someone else’s server.

My demo of OpenTelemetry Tracing features two Spring Boot components. One uses the Java agent, and I noticed a different behavior when I recently upgraded it from v1.x to v2.x. In the other one, I'm using Micrometer Tracing because I compile to GraalVM native, and it can't process Java agents. I want to compare these three different ways in this post: Java agent v1, Java agent v2, and Micrometer Tracing.
