Building a Monitoring System for Jobs That Never Ran
https://www.reddit.com/r/programming/comments/1q4dsko/building_a_monitoring_system_for_jobs_that_never/

<!-- SC_OFF -->Most monitoring systems tracks success and failure, but the hardest problems come from jobs that never ran at all. The article covers the architecture, the tricky parts such as detecting jobs that never ran, and some lessons learned along the way. <!-- SC_ON --> submitted by /u/Mythikos (https://www.reddit.com/user/Mythikos)

Simple and efficient visualization of embedded system events: Using VCD viewers and FreeRTOS trace
https://www.reddit.com/r/programming/comments/1q4l6jy/simple_and_efficient_visualization_of_embedded/

<!-- SC_OFF -->Relying on printf or simple breakpoints for real-time embedded debugging is often like flying blind - especially when dealing with complex timing and RTOS scheduling. The RTEdbg toolkit (https://github.com/RTEdbg/RTEdbg) has been extended to solve this, adding VCD-based (https://en.wikipedia.org/wiki/Value_change_dump) event and data visualization, native FreeRTOS trace support, and enhanced trace macros for deeper system insights. Because RTEdbg is open-source, it is accessible for any project, regardless of budget. It supports application and RTOS event visualization (see FreeRTOS trace demo (https://github.com/RTEdbg/FreeRTOS-trace-demo)) and allows for flexible data export and custom visualization—you can see it in action here: Various Data Export and Visualization Possibilities (https://github.com/RTEdbg/RTEdbg/blob/master/Views.md). <!-- SC_ON --> submitted by /u/BrankoP88 (https://www.reddit.com/user/BrankoP88)

Functors, Applicatives, and Monads: The Scary Words You Already Understand

<!-- SC_OFF -->Do you generally agree with this? It's a tough topic to teach simply, and there's always tradeoffs between accuracy and simplicity... Open to suggestions for improvement! Thanks :) <!-- SC_ON --> submitted by /u/cekrem (https://www.reddit.com/user/cekrem)
