InfluxDB
InfluxDB – Database Purpose-Built for High-Resolution Data. Turn time series data into real-time intelligence. Manage high-volume, high-velocity data without sacrificing performance.

> A running number also carries data. Before you know it, someone's relying on the ordering or counting on there not being gaps - or counting the gaps to figure out something they shouldn't.
For example, if https://github.com/pytorch/pytorch/issues/111111 can be seen but https://github.com/pytorch/pytorch/issues/111110 can't, someone might infer the existence of a hidden issue relating to a critical security problem.
Whereas if the URL was instead https://github.com/pytorch/pytorch/issues/761500e0-0070-4c0d... that risk would be avoided.

nn
🧑🏫 60+ Implementations/tutorials of deep learning papers with side-by-side notes 📝; including transformers (original, xl, switch, feedback, vit, ...), optimizers (adam, adabelief, sophia, ...), gans(cyclegan, stylegan2, ...), 🎮 reinforcement learning (ppo, dqn), capsnet, distillation, ... 🧠

In practice, you’ll want to use libraries (like scikit-learn or TensorFlow.js for more advanced modeling), but the principle remains: find what similar users enjoy, and use that as a basis for recommendations.

Project mention: Why DETRs are replacing YOLOs for real-time object detection | news.ycombinator.com | 2025-11-22
> The YOLO series is developed and maintained by Ultralytics. All YOLO code and weights are released under the AGPL-3.0 license.The YOLO series is developed and maintained by Ultralytics. All YOLO code and weights are released under the AGPL-3.0 license.
The original author of YOLO and the Darknet framework [1] issued the code under pretty much every license you wish to use [2]. My preferred fork by AlexeyAB is under an equally permissive license [3].
Ultralytics then created their own model under the AGPL-3.0 license [4], which probably would never stand up in a court as they have the model from the likes of YOLOv3 in their source [5].
This entire article is flawed anyway, because they don't state which YOLOv11 model they are using or compare the accuracy. They appear to have just taken the pre-trained models and assumed it's apples-to-apples. They could have at least compared YOLO11n/s/m/l/x,
