[Verse 1] Python in the lab where we crunch the data cold Pandas, NumPy, matplotlib — the analysis unfolds Trajectory equations plotted, orbital windows mapped Every delta-v computed before the payload's strapped But when the rocket's breathing, Python steps aside C plus plus takes the cockpit, deterministic stride No garbage collector pausing mid-burn in the sky Hard real-time constraints — microseconds define alive [Chorus] Código que voa, não pode falhar Versão controlada, commit, testar Sistema embarcado, ciclo preciso Um bug no firmware é um voo indeciso Escreve o teste, empurra o branch, revisa Computação que lança — essa é a empresa [Verse 2] Embedded systems talking to the hardware direct Interrupt service routines — the scheduler must respect Deterministic timing, every loop a bounded clock A missed deadline in flight software puts the mission in a box Memory allocation static, no dynamic heap at night Stack overflow on orbit means the telemetry goes white RTOS scheduling threads with priority assigned Rate-monotonic theory keeping every process lined [Chorus] Código que voa, não pode falhar Versão controlada, commit, testar Sistema embarcado, ciclo preciso Um bug no firmware é um voo indeciso Escreve o teste, empurra o branch, revisa Computação que lança — essa é a empresa [Verse 3] Simulation before steel — model everything first Six-degrees-of-freedom physics, rehearse the best and worst Monte Carlo scatter plots across ten thousand runs Perturbing every variable, not just average suns Ariane Five exploded from a cast that overflowed A value too wide for the register — legacy code corrode Simulation caught it? No. Testing? Insufficient depth Version control and review culture — that's the safety breath [Bridge] Git blame never lies — the history stays honest Every merge request reviewed, nobody works anonymous Unit test, integration test, hardware-in-the-loop Regression suite before each build closes every loop Formal verification where the stakes demand the proof Mathematical certainty, not confidence — the truth Simulação é o ensaio, o código é o ato Testa antes de lançar — esse é o trato [Verse 4] Branch the feature, freeze the baseline, tag the release build Continuous integration — every night the pipeline filled Static analysis scanning for the undefined behaviour MISRA rules for flight code, disciplined as a surveyor Two engineers must sign before the binary flies Not bureaucracy — respect for what a bad pointer implies Python models feed the C — the languages co-exist One computes the answer, one ensures the answer persists [Chorus] Código que voa, não pode falhar Versão controlada, commit, testar Sistema embarcado, ciclo preciso Um bug no firmware é um voo indeciso Escreve o teste, empurra o branch, revisa Computação que lança — essa é a empresa [Outro] Código limpo, sistema robusto Every astronaut above us built on software we can trust
