Pointers and Memory in C and C++, Without the Fear
1+ hour, 22+ min ago (1346+ words) Originally published on Code Beneath. In Java, you think in references. In Go, the language decides whether a value lives on the stack or heap, and you rarely care. In C++, you decide, and you see the consequences immediately. Let…...
TASKING integrates software tracing with SafeRTOS for embedded timing analysis
1+ hour, 48+ min ago (212+ words) Military Aerospace TASKING integrates software tracing with SafeRTOS for embedded timing analysis MUNICH - TASKING has integrated its Software Trace (SWAT) tool with SafeRTOS, a real-time operating system from WITTENSTEIN high integrity systems, to provide operating-system-aware timing analysis for embedded systems…...
A Property Counterexample Is Not a Flake You Can Freeze
2+ hour, 35+ min ago (1265+ words) A flake freeze is an exemption record, not a passing result. An agent patch may carry one only when three conditions hold at once: the skipped assertion has a named nondeterminism class, the property lane is green on a pinned…...

Class the Shrunk Witness Before a Property Failure Can Be Frozen
9+ hour, 27+ min ago (1384+ words) A property failure is not a flake freeze. It becomes eligible for a freeze only after the input is shrunk, retained, replayed on a pinned fixture, and classed as unstable rather than consistently wrong. A witness that fails on every…...

C++ Abstract Classes and Interfaces: Build a Usable Storage Contract
22+ hour, 34+ min ago (798+ words) Build a C++17 ScoreStore interface, swap vector and hash-backed implementations behind it, and verify both with the same runnable contract test. Exam prep & CS education C++ has no interface keyword. A class is abstract when it has at least one…...
Canary Fixture Binding With Identity Failure Classes and a Halt Gate
12+ hour, 6+ min ago (1202+ words) Last Tuesday I replayed an agent evaluation that was supposed to remain inside one synthetic lab scope. The third tool call departed carrying a hostname that I had never written into the fixture contract. The planner had already consumed a…...
agent-guard 0.7: the legit-test-change escape hatch
16+ hour, 21+ min ago (210+ words) You asked, I built it. In the comments on the last agent-guard post, Coldboot asked the uncomfortable question: "how does the guard know a test change is legitimate?" Updating a snapshot, fixing a flaky timing test, adding a fixture — the…...
Designing Deterministic Value Resolution for Competing Gameplay Systems in Unreal Engine
16+ hour, 34+ min ago (1098+ words) This origin shaped VRS's scope: its subject is not a particular effect, such as a buff, but the interaction between systems that influence the same gameplay value. Consider a character whose movement speed depends on equipment, terrain, and scripted restrictions....
