How Ottawa’s changing garbage collection might affect you
The City of Ottawa has a new garbage collection contract that takes effect on March 30. It means new routes and schedule changes for about half the city. And as Arthur White-Crummey reports, for some it could mean a longer one-time transition period.

Dissecting the CPU-Memory Relationship in Garbage Collection

Every time you configure a Java application’s heap size, you are essentially making a trade-off: spending more on infrastructure to improve performance metrics such as throughput or latency. Historically, this trade-off was visible when an undersized heap triggered long pauses, signaling a need for more resources. With modern collectors, however, pause duration and computational effort have become decoupled. This creates an operational blind spot: dashboards may show excellent response times, while the collector silently consumes excess compute capacity to compensate for a constrained heap. To address this, it is essential to look beyond GC pauses and examine overall efficiency using new tools. This article, therefore, analyzes why we need additional metrics for infrastructure efficiency and introduces the new Java API for GC CPU in OpenJDK 26, which empowers engineers and researchers to quantify the collector’s CPU overhead and make informed memory-CPU trade-off decisions.

It’s about to get a lot easier for your JavaScript to clean up after itself

There’s some very useful capabilities coming to JavaScript: “[Symbol.dispose]()” and “using”. Mat Marquis is here to explain why they’re coming and how to use them effectively.

Lambda Captures Entire Scope Consuming 47GB RAM?!

LAMBDA MEMORY DISASTER! Closures capture ALL local variables! 1M lambdas × 5KB = 5GB RAM! Can't garbage collect! System thrashing! Event handlers lost! $890K recovery! Architect FIRED!

Corner Brook's new automated garbage collection is learning curve for staff, residents
The City of Corner Brook launched a new garbage collection system in mid-January that features automated garbage trucks and a new schedule for recycling pick-up. The city says the changes will cut down on some costs and make the work easier for staff. But it may ...
