#SLF4J
It's not one of those "if it seems too good to be true" options. It's just a step up, in the same way Slf4j + <provider> is over the std logger offering.

``log`` is this slightly overengineered slf4j stuff. ``tracing`` is like somebody made Spring for Log4j

core JDK APIs - they're good facilitators, but rarely best in class. I'd propose EC should be as ubiquitous as SLF4J and other common libs - why should one of the most fundamental components of programming be defaulted to a lesser solution.

or like, the http library/framework I'm using does string interpolation in its log messages

so even for log messages which don't get printed, you still incur the overhead of the string interpolation

whereas with something like SLF4J, you would do

logger.info("some message %s", "some […]

Optimising your memory allocations in Java could make far more difference than your choice of Garbage Collector, and may even change which garbage collector is best. Chronicle FIX already persists each message; what if we use SLF4J/logback to write another copy

And the utilities to back it up:
✅ parse - effect for parsers
✅ config - typed feature flags & structured config
✅ stats-otlp - pure Scala OpenTelemetry
✅ logging-jpl/slf4j - logging bridges

AWS Transform custom introduces new AWS-managed transformations to modernize code at scale
AWS Transform custom now offers seven new AWS-managed transformations to help you modernize code at scale. These transformations address common modernization scenarios across multiple languages and frameworks. Generally available transformations includes comprehensive codebase analysis transformation, enabling you to generate hierarchical, cross-referenced documentation covering architecture, business logic, and technical debt, with actionable insights on outdated components and maintenance concerns. The Node.js version upgrade transformation is now generally available and includes comprehensive library upgrade support, enabling you to upgrade Node.js applications from any source version to any target version with full dependency modernization. Those transformations available in early access include Java performance optimization transformation helps you analyze Java Flight Recorder (JFR) profiling data to detect CPU and memory hotspots and anti- patterns, then applies targeted code fixes to reduce resource usage and improve efficiency. The Log4j to SLF4J migration transformation allows you to remediate Log4j logging dependencies by migrating to the SLF4J logging framework. Also available in early access is the Angular to React migration transformation transforms Angular applications to React. The Angular version upgrade transformation enables you to upgrade Angular applications to the latest version. Finally, the Vue version upgrade transformation upgrades your Vue.js applications to the latest version. AWS-managed transformations are validated by AWS and can be customized to meet your organization's specific requirements. All transformations benefit from continual learning, automatically improving quality from every execution. To get started, install the AWS Transform CLI and run atx custom def list to see all available transformations. For more information, see AWS-Managed Transformations. AWS Transform custom is available in US East (N. Virginia) and Europe (Frankfurt).

Why on earth is it so hard to find how change the log level being output to stdout with slf4j. Like how is this not just a simple command line arg that is the first result when I search.

Found some time to finally write a blogpost on an easy to implement alternative to Lombok's Slf4j annotation in my favourite IDE. Let me know if this was also useful for you 👍

10 Essential Java Libraries - How Essential Are They Really?
