Published: 2025-05-01 | Origin: /r/programming

On April 24, 2019, Blizzard launched the Overwatch Workshop, a scripting platform enabling players to create custom gamemodes for Overwatch. This platform utilizes an event-driven system rather than traditional linear programming, focusing on rules that activate actions when specific conditions are met. While the Workshop allows for creative game design, it initially faced limitations: players had to use a limited set of 26 variables without names, resulting in reliance on reference sheets to track them. There were no comments allowed in

Redis is now available under the the OSI-approved AGPLv3 open source license.

Published: 2025-05-01 | Origin: /r/programming

Redis 8 has been released as an open-source project, addressing challenges posed by cloud providers like AWS and GCP, which benefit from open-source software (OSS) without sufficiently contributing back. To protect their innovations, companies such as MongoDB and Elastic have adopted the Server Side Public License (SSPL). Redis initially opted for a different strategy with Redis Stack, but this divided the development experience and hindered progress. After a year of evaluation, Redis transitioned to the SSPL in March 2024

Why sharing a redis cluster across services is asking for trouble

Published: 2025-05-01 | Origin: /r/programming

The content discusses the challenges faced by software engineers when using a single cache cluster shared across multiple services in distributed systems. Initially, the decision to use an existing cache cluster may seem simple and efficient, but as services scale, it leads to complications such as lack of isolation between services. A sudden spike in cache writes can hit the cluster's maximum memory, causing key evictions that negatively impact various services simultaneously. This results in confusion for engineers trying to pinpoint which service is causing issues, creating additional noise and
