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.

For the longest time now, I have been obsessed with caching.

In the years immediately following the dot-com meltdown, there was more tech labor than there were tech jobs. That didn’t last long. By 2005, the tech economy had bounced back on its own. After that, the emergence of mobile (a new and lucrative category of tech) plus low interest rate policy by central banks fueled demand for tech. Before the first decade of the century was out, “tech labor scarcity” became an accepted norm.

Teams often consider external caches when the existing database cannot meet the required service-level agreement (SLA). This is a clear performance-oriented decision. Putting an external cache in front of the database is commonly used to compensate for subpar latency stemming from various factors, such as inefficient database internals, driver usage, infrastructure choices, traffic spikes, and so on.

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.

I recently compared three OpenTelemetry approaches on the JVM: Java Agent v1, v2, and Micrometer. I used Kotlin and coroutines without overthinking.

However, it made me think about the underlying workings of OpenTelemetry.
