Network

Plan 2.4, 5, and 6 GHz Wi-Fi channels from measured AP channels, widths, and RSSI, with overlap, DFS, and PSC warnings.

Development

Rewrites span/log attribute names across OpenTelemetry semantic-convention versions: http.method → http.request.method, http.status_code → http.response.status_code, http.url → url.full, db.system → db.system.name, messaging.destination → messaging.destination.name and 25+ more — applied to pasted JS/TS/Python/Go/Java/.NET source, collector YAML or Grafana dashboard JSON, with an OTel Collector transform rename map, removal/manual-split warnings, per-attribute diff stats and an unmapped-attribute report.

Development

Validate W3C Trace Context propagation headers end to end: traceparent (version / 16-byte trace-id / 8-byte parent-id / trace-flags), tracestate (≤32 list members, tenant keys), baggage (percent-encoded values + opaque properties), OTLP export Content-Type, the gRPC grpc-trace-context-bin 25-byte binary context — plus a two-header correlation round-trip with a random child span-id collision check.

Network

Decode a PCIe link training log (LTSSM state sequence plus TS1/TS2 ordered sets) into the full Gen1-Gen6 state timeline: negotiated speed and width, rate identifier bits, lane reversal, polarity inversion, equalization phases and Detect/Recovery restart diagnostics. Also grades a lane margining report (pcilmr CSV or key=value) against the PCIe Base Spec Rev 5.0 §8.4.2 eye minimums per generation and renders a per-lane eye-margin heatmap SVG.

Network

Audit a domain end to end: IANA RDAP bootstrap referral, registry/registrar WHOIS data, and the DNSSEC chain of trust from the root KSK through the TLD DS to the apex DNSKEY — with DS digest verification and RRSIG expiry flags.

Development

Test PCRE2 patterns online: every named-group syntax ((?P<n>), (?<n>), (\u0027n\u0027)), possessive quantifiers, atomic groups, \A \z \h shorthands, plus pcre2grep and C API snippets.

Development

Turn an OpenAPI 3.x or Swagger 2.0 spec (JSON/YAML) into an importable Postman Collection v2.1.0 with folders, variables, auth and example responses.

Development

Decode raw WebSocket frames (hex or base64) byte by byte per RFC 6455: FIN/RSV/opcode, MASK bit, extended lengths, masking key, unmasked payload, close codes, and protocol-violation warnings.

Development

Connect to any WebSocket (ws:// or wss://) endpoint from your browser, send and receive messages, and inspect open/close/error events with codes — ideal for debugging real-time APIs and sockets

Development

Generate high-quality website screenshots with customizable options using headless browser

Network

Query WHOIS domain registration information including registrar, dates, and name servers

Development

Convert Unix timestamps between hexadecimal and decimal/ISO — paste 0x5F6B3A2F, a bare 8-digit hex value, decimal seconds or milliseconds, or a date, and get every form back.
