   When it works, its mediocre

   As a DM for homebrew games, I used Roll20 for 2+ years. When it works, its OK. When it doesn't, its frustrating. I use a lot of custom rules and they are simply not supported due to a lack of modularity within the system. A simple variant of Proficiency Dice in 5e is outlined in the rules, and even it is hacky and not well supported on Roll20.

   The format feels like it was made two decades ago, and the web console spits out warnings and errors left and right. There has even been some conspiracies / drama with some of the higher-ups at Roll20, showing a lack of leadership.

   Please, let's let Roll20 die. Support another system.

   👍 Pros:    Can purchase modules like curse of strahd and tomb of annihilation|Free for dms and players|Use with a variaty of systems|Many features

   👎 Cons:    Not modular enough for me|Hacky programming|Ugly|Features feel clunky and slow|Some features do not work well at all|Buggy

• My homelab stack in 2026: what runs, why, and how it all connects

  Prometheus scrapes metrics from the stack. Node exporter covers the host, cAdvisor covers containers, and individual services expose their own endpoints where supported. The main value isn't dashboards (though those exist) - it's having a queryable record of system state over time, and a place to hook alerts when something drifts. - Source: dev.to / 23 days ago

• Best Open Source Monitoring Tools in 2026: 7 Self-Hosted Options Compared

  Prometheus is the industry-standard time-series database for infrastructure metrics. Paired with Grafana for visualization and Alertmanager for routing, it forms the backbone of monitoring at companies from startups to Netflix-scale deployments. This isn't a single tool — it's an ecosystem. - Source: dev.to / 30 days ago

• Rate Limiting in Spring Boot REST APIs: Bucket4j + Redis

  To monitor and analyze rate limiting metrics, we're using a combination of Redis and Prometheus. We're storing rate limiting metrics in Redis and then using Prometheus to scrape the metrics and display them in a dashboard. Here's an example of how we're storing rate limiting metrics in Redis:. - Source: dev.to / about 1 month ago

• Chronos vs Toto: Zero-Shot Forecasting Benchmark Results

  In this post, we compare two forecasting models, Chronos (Chronos‑Bolt) and Toto, on telemetry from Prometheus and OpenSearch. We judge them with two easy metrics: MASE for point accuracy and CRPS for the quality of uncertainty. - Source: dev.to / about 2 months ago

• The Real Cost of Silent Data Pipeline Failures

  For monitoring infrastructure, Prometheus and Grafana are widely used for pipeline metrics collection and alerting. For orchestration that includes built-in run observability, Apache Airflow tracks run history, task durations, and failure states in a web UI. Python with SQLAlchemy is the standard stack for custom pipeline implementation with relational state management. - Source: dev.to / 3 months ago

• Friend screwed 3/4 of the table out of 1/2 the game.

• Looking for a DND/TTRPG group

  I've used roll20.net up until now. They have a find group feature and a virtual table top with character sheets and dice roller included, so everything you need to play virtually is all on the one site. Source: over 2 years ago

• Looking for advice on running DnD game on stream!

  There are plenty of D&D software programs out there that are free and paid versions. Many of them with the ability to have friends join and interact with the table. As basic as Tabletop Simulator to Fantasy Grounds (both on steam that I have experience with, not an endorsement). roll20.net being a popular browser based version. Source: over 2 years ago

• I'm looking for someone to teach me how to Play DnD

  I have made a character on roll20.net that maybe border line iffy/OP, so I may have to make one that's not. My free time can be a bit unusual at times(it's 12:24AM as I write this)so someone who has similar free times as I do(if your interested let me know and we can talk times), basicly I've been listening to a DnD podcast and I think it sounds fun and I want to try it out Edit: I'm in PST timezone in...
