Goal is to reduce CI resource use for a low-traffic workload by running only a subset of examples selected via RSpec metadata filtering. The focus tag feature uses config.filter_run :focus to execute only examples marked focus: true . When no examples are tagged, the suite behavior depends on config.run_all_when_everything_filtered , and the feature has been
When designing smart contracts for low-traffic workloads, minimizing gas expenditure during function execution is a priority. Solidity 0.8.x provides different data locations for function parameters, specifically memory and calldata . While calldata is documented as a non-modifiable, non-persistent area where function arguments are stored, the specific gas t
I'm designing the failure-reporting layer for a Solidity dapp (compiler pinned to 0.8.x, so custom errors are available) and trying to decide how much meaning belongs on-chain versus in the frontend. The contracts currently mix require(condition, "long message") strings with a few error Unauthorized(address caller); -style custom errors, and the revert strin
Karate Scenario Outlines driven by `read()` load entire CSV or JSON files into the heap before iteration begins. This design means a 100 kB test data file can trigger OutOfMemoryError under constrained -Xmx settings, and no public API exists for lazy row extraction or bounded iteration. The framework's pagination support for REST API responses requires manua
The goal is to enable a transaction to be gracefully aborted or bounded when execution time exceeds a safe limit. In Starknet, the Cairo‑VM enforces a gas‑based metering system, but gas limits are not a direct proxy for wall‑clock time. Moreover, once a transaction is included in a block, cancellation is only possible by failing the gas check, which is a har
Jaeger Tracing Sampling A configuration utilizing a static local sampler functions correctly in a local development environment. Production Sampling Failure This same setup results in zero sampled traces when deployed to production infrastructure. What is the documented fallback behavior of Jaeger client libraries when the remote sampling endpoint is unreach
The KrakenJS framework relies on a modular architecture where functionality is extended through a plugin-based system. While the kraken.js configuration file defines environment-specific middleware, specific challenges arise when multiple asynchronous plugins interact with shared state. When several plugins are registered to modify the same global request ob
Selective Notification Suppression in GoLand GoLand's global notification settings under Settings | Appearances & Behavior | Notifications allow disabling build-completion pop-ups for all languages. However, this all-or-nothing approach may hide useful alerts in other runtimes or plugins. GoLand 2024.1+ introduces the ide.no.notifications property that c
We run a small Twilio-based SMS service (a few long-code numbers, roughly 2k messages/day) and are planning a move to an alternate carrier. The hard constraint is zero downtime: inbound and outbound messages must keep flowing during the cutover. The open decision is whether to keep using long codes on the new carrier or take the opportunity to move to a dedi
