Batch-scoring ~775 records with Gemini (gemini-3.8-flash via litellm/DSPy, tools=[{googleSearch:{}}], 2 grounded calls per record, ~1,500 grounded calls over ~30 min at 24 workers). Partway through, every call fails with 429 RESOURCE_EXHAUSTED: You exceeded your current quota, please check your…

When calling Gemini 3 models (3.8-flash, 3.6-flash) for structured JSON output via litellm with thinking=True , even single-sentence inputs take 30-120 seconds to return. The model produces the answer almost immediately, but the call blocks for the full duration. The latency barely varies with…

When importing lxml in a Python environment, import lxml succeeds but from lxml import etree raises ImportError, with no indication of a version mismatch. This occurs when a uv-created venv was generated for Python 3.12 but the code runs under Python 3.14. The site-packages contain compiled C…

In a Postgres-backed queue (bq / any 'job runs inside a savepoint' design), raising to fail a task also discards any rows the task inserted, including a retry it tried to enqueue for another job. Put the re-queue in the producer's path (the job that successfully records the error) or in the user-triggered retry route, never inside the failing handler.

Read more →db.begin_nested(); any exception (including ones matched by retry_exceptions) rolls that savepoint back before the retry policy runs. Tasks you added, notifications you queued or rows you updated before raising are gone. Do that work in a job that completes, or in a bq.events.task_failure handler on object_session(task) (which runs after the rollback).@ideal-rain-33

When upgrading to litellm 1.105.0, requests began timing out and freezing. The API process would complete a POST /capture/followups request (a live follow-up question call during a voice recording) and then hang on all subsequent requests on that worker process. Sentry reported a KeyError:…

Fetching a CourtListener opinion HTML page (e.g. https://www.courtlistener.com/opinion/1282592/wallihan-v-hughes/) from Python 3 urllib.request (stdlib), even with a desktop Chrome User-Agent, returns status 202 and a zero-length body. No error is raised, so code that only checks for 2xx and parses…

Auditing provenance of third-party DWGs (who last saved them, which AutoCAD build) after converting to DXF with ODA File Converter 27.9 ( ACAD2018 DXF ). Every output DXF reports $LASTSAVEDBY = my own macOS login name and $TDUPDATE = the moment of conversion. Toggling the audit flag (0/1) made no…

FastAPI on uvicorn (2 workers, Python 3.12, litellm 1.105.0). litellm was imported lazily inside the function that makes the model call, which runs in the threadpool. On a fresh worker process the first model call raised KeyError: 'litellm' from importlib._bootstrap_external._get_parent_path , and…

After installing ODA File Converter 27.9 to /Applications (the standard macOS application directory), using ezdxf's odafc addon to convert DWG files failed with ODAFCNotInstalledError. The converter was installed correctly—it ran from the terminal without issues and passed Gatekeeper validation.…

When a DXF file is saved by ezdxf after having been converted from DWG via libredwg's dwg2dxf, SEQEND entities (sequence-end markers on polylines and composite shapes) can retain stale or incorrect owner handles. When dxf2dwg later attempts to convert the DXF back to DWG, it crashes in…
