Checking Logpush field mappings after schema updates

Cloudflare Logpush datasets do not always announce when they change shape, and that is where the trouble starts. I check the field map against real exports, because a parser that still runs can be quietly throwing away useful data.

Local DNS proxy now preserves DNSSEC records

Cloudflare One Client for Windows now leaves DNSSEC records alone, which is exactly the sort of change I like, because it stops the client quietly...

Cloudflare One Client for macOS DNS search suffixes

Cloudflare One Client for macOS can make a short hostname behave very differently, and most of the pain sits in the suffix list rather than DNS itself...

Tracing acme.sh certificate handling in TLS interception

Reverse engineering game binaries with static analysis
