<!-- SC_OFF -->In DDD, an aggregate is a consistency boundary, not just a container for related data.

Measuring Jitter: Standard Linux vs PREEMPT_RT under heavy load
https://www.reddit.com/r/programming/comments/1se3lsn/measuring_jitter_standard_linux_vs_preempt_rt/

<!-- SC_OFF --> I've been working on a Software PLC where microsecond-level execution timing is critical. To guarantee real-time performance, I tested and compared the scheduling jitter between a standard Linux kernel and a PREEMPT_RT patched kernel (Ubuntu 24.04). The Setup: A C++ task waking up every 10ms using clock_nanosleep, running for 10,000 iterations. Applied heavy system load using stress-ng (CPU 100%, Disk I/O, Context switches, Page faults). CPU governor set to 'performance'. The Results (Worst-case Jitter): Standard Linux Kernel: Extremely unpredictable. Jitter spiked up to ~650 µs when the system was under stress. PREEMPT_RT Kernel: Very stable. The worst-case jitter was strictly bounded under 70 µs. It's impressive how much stability the PREEMPT_RT patch brings to a general-purpose OS without needing a dedicated RTOS. I also learned a hard lesson about not doing File I/O inside an RT loop the hard way! 😅 Any feedback or tips on further tuning (like IRQ Affinity) would be greatly appreciated! <!-- SC_ON --> submitted by /u/Special_Ad5912 (https://www.reddit.com/user/Special_Ad5912)

C3 closes out its 0.7 era — focusing on simplicity and control before 0.8

<!-- SC_OFF -->C3 is trying to stay close to C in terms of control and predictability,
without piling on too much complexity This release is mostly about tightening semantics, improving inference,
and removing edge cases before moving into the 0.8 cycle. It’s less about adding features and more about making the language and standard library consistent. <!-- SC_ON --> submitted by /u/Nuoji (https://www.reddit.com/user/Nuoji)
