Secure connectivity principles in water sector OT

Secure connectivity principles only work when the boundary is real, not decorative. I’ve seen too many remote paths that looked neat on paper and fell apart the moment someone needed to patch a PLC at 2am; that is usually where the trouble starts.

Monitoring radio, transport and core faults

Private 5G resilience does not come from a cheerful dashboard or a nice radio map. I want to see where the attach failed, which path dropped, and...

Pre-boot authentication for BitLocker

TPM-only BitLocker is convenient, but convenience is not the same as a proper boundary. BitLocker PINs push that line back to pre-boot, which is where...

Single-sided BPool joins drain mOCEAN via SideStaking

Ocean Protocol BPool single-sided join exit math is where this one falls apart, and I have a soft spot for bugs that look tidy until another contract...

Tracing acme.sh certificate handling in TLS interception

I spent too long chasing the neat version of TLS wiretapping reconstruction, then found the mess: shell parsing, token limits, and renewal timing. The interesting bit is not the packet capture, it is...

Reverse engineering game binaries with static analysis

Game binaries give up more than they should, if you know where to look. I start with binary analysis, not the folklore around the game, then use strings, imports, and control flow to separate real...

Agentic AI still needs domain judgement

Agentic AI can write the thing, but it still cannot tell you whether the thing is right. That is where domain expertise matters, because a clean config or neat bit of glue logic can still be wrong in...

wolfCOSE zero-allocation parsing in embedded C

wolfCOSE looks sensible only if you care about what your firmware actually has to carry. I like that, because on small targets the wrong crypto feature can cost more than the message itself, and there...

Layout trade-offs in Design Engineering Magazine

Design Engineering Magazine only works if the structure holds under real reading, not just in a tidy mock-up. I care less about pretty grids than about whether the archive, type and page weight stay...

Keeping smart bulbs powered with Zigbee wall switch

Zigbee wall switch controllers fix the bit people keep getting wrong, the wall still feels normal, but it stops murdering smart bulbs. I prefer that to rewiring a room just to keep the lights alive;...

Home Assistant Matter alarms for local CO alerts

Home Assistant Matter alarms are only worth bothering with if they still behave properly when the mesh sulks or the border router falls over. I prefer that sort of boring reliability, because a CO...

Chunked range reads with etcd RangeStream

etcd RangeStream is one of those changes that sounds minor until you watch a large read stop clogging memory on both ends of the RPC. I like it because it replaces one ugly pause with a series of...

Why Kubernetes CVE records still flag unfixed issues

Kubernetes CVE records can say “fixed” when nothing was actually fixed, and scanners will believe them. I have seen that sort of paperwork mistake turn into quiet false negatives, then loud surprises...
