SearXNG: Engine Selection for Reliable Results

If you’re running SearXNG as a self-hosted search backend for an automated pipeline, the default engine selection will cause you problems quickly. Here’s what we’ve found running SearXNG 24/7 for a federal procurement intelligence pipeline. What doesn’t work Google — returns 403 Forbidden for bot-detected requests. Happens immediately on most self-hosted instances without aggressive Cloudflare bypass configuration. Don’t rely on it for automated queries. Startpage — CAPTCHAs after a few queries. Fine for occasional manual searches, unusable for scheduled pipelines. ...

Running Qwen3.5-122B on a Single DGX Spark

The NVIDIA DGX Spark (GB10 SoC, 128GB unified LPDDR5X memory) can run Qwen3.5-122B-A10B — a 122B parameter MoE model — at usable throughput for production workloads. Here’s what it actually takes. The key constraint: NVFP4 only Qwen3.5-122B-A10B at full precision is ~250GB. In NVFP4 quantization it’s ~75GB, which fits comfortably in 128GB unified memory. There is no other quantization path that both fits and runs correctly on the GB10. The only verified checkpoint we’ve found: bjk110/SPARK_Qwen3.5-122B-A10B-NVFP4 on HuggingFace, which includes 15 patches for the SM121 architecture. Use this; don’t try to quantize the base model yourself unless you’re prepared to debug SM121-specific kernel failures. ...

USASpending API: How to Actually Query HHS Sub-Agencies

If you’re building anything that pulls contract award data from USASpending.gov and you need to filter by HHS sub-agency (NIH, FDA, CDC, CMS, AHRQ), you’ve probably hit this: the subtier name filter returns nothing. What doesn’t work body = { "filters": { "agencies": [ {"type": "awarding", "tier": "subtier", "name": "Food and Drug Administration"} ] } } Returns {"results": [], "page_metadata": {"total": 0}} — every time, for every HHS component, regardless of how you spell the name. The API accepts the request without error. ...

SAM.gov Opportunities API: The NAICS Filter Does Nothing

The SAM.gov Opportunities API v2 accepts a naics query parameter. The documentation implies it will filter results to matching NAICS codes. It doesn’t. What actually happens GET https://api.sam.gov/prod/opportunities/v2/search?api_key=...&naics=541511&limit=100 Returns opportunities with NAICS codes 541330, 561210, 711510, and anything else currently open — not just 541511. The filter is parsed, no error is returned, but the result set is unfiltered. This appears to be a persistent bug in the v2 API. It isn’t mentioned in the documentation. ...
