Fourteen years of WordPress work, one recurring problem: everything ends up in functions.php. Here are the five layers I use to separate hooks, workflows, business rules, database access and outside services, plus a before-and-after AJAX handler.
Multi-GPU training usually stalls on communication, not compute. What nvidia-smi topo and Nsight show you about NCCL overhead, and the DDP settings I change: static graph, bucket views, PowerSGD compression and smaller buckets.
Dongxiang has almost no parallel data, so we fine-tuned Meta’s NLLB-200 instead of prompting a general model. Cleaning the bilingual corpus, checking subword fertility, registering a new language tag, and why Adafactor beat AdamW on one GPU.
Prediction models find patterns; they do not tell you what an action will cause. This post walks through the causal toolkit for that: potential outcomes, DAGs, de-biasing with OLS, propensity matching, and difference-in-differences.
Cursor’s indexer is a RAG pipeline: tree-sitter splits code at logical boundaries, embeddings land in Turbopuffer, and Merkle trees keep the index in sync. Here is how the pieces fit together, and what actually leaves your machine.
For a docs bot or an internal MVP, a dedicated vector database is more infrastructure than the problem needs. Vector search is matrix multiplication, and NumPy handles it in milliseconds. Includes a small store class, the SciKit-Learn upgrade path, and the four signs you have outgrown both.
Moving a Ray job off your laptop and onto an AWS cluster: the YAML that defines the nodes, the vCPU quota that will bite you, and why ray down matters more than any tuning flag.
A side-by-side look at Azure ML and AWS SageMaker: Workspace-centric RBAC against job-level IAM roles, Datastores against raw S3 URIs, and which one holds up once training moves off notebooks.
The core team confirmed at Dev Chat that WordPress 7.0 drops PHP 7.2 and 7.3 support. Notes on what that leaves for the 22% of sites still running 7.4, plus where the 6.9.1 maintenance release fits in.
The z-score is fine for a single spike and falls apart on trends. Why the T-statistic is the right measure for slope significance, with PHP you can drop into a custom reporting engine.
