@#8176 Fun fact. [The quants](https://en.wikipedia.org/wiki/Quantitative_analysis_(finance)) use floating point money in their calculations. But they don't require high accuracy. Accounting requires accuracy down to a penny. (more) |

Hungarian notation would be something like `dictLogRecord`. `log_record_dict` is snake case, and not at all Hungarian. More about the departure of Hungarian notation here: http://prolifictec.com/blog/2014/09/hungarian-notation-in-microcontroller-code.html (more) |

@#53890 In the O.P.'s code the `dict` is contents of one log record, as opposed to a collection of several records. I think that the variable name is okay, considering that it's a short-lived local. (more) |

A: Declaring a callback function in `usart.h`, using it in `usart.c` but defining it in `main.c` [ `rbput(UDR0)` sounds like an AVR. I'll be using STM32 in some examples, because I'm not familiar with AVRs. You were asking about about STM32 on EE.Codidact recently. ] > But I have a gut feeling that this is wrong. It feels wrong that I handle an intrinsic UART construct `UDRE0` in `main.c`... (more) |

A: JSON log formatter Some exception objects carry additional fields. For example, a `subprocess.CalledProcessError()` exception carries `returncode`, `output` (the stdout), `stderr`, etc. It’s useful information, but self.formatException() ignores it. You can add a few lines which format the extra fields, and save... (more) |

| Question | — |
Concise way to capture stderr output in an exception when calling a process from Python I’d like to call an external executable from a Python script. If it exits with a nonzero code, I’d like an exception containing the return code and the `stderr` output. The exception will be caught and logged by the `UncaughtExceptionHook`. The `subprocess.checkcall(…)` would be nice and conci... (more) |

Here’s a tutorial about `extern` . It [starts at the end of this page](https://cs.emory.edu/~cheung/Courses/255/Syllabus/1-C-intro/cprep2a.html) and [continues at the beginning of this one](https://cs.emory.edu/~cheung/Courses/255/Syllabus/1-C-intro/cprep3.html). It explains how to set up `exte... (more) |

A: A state machine in Python I think you've got an architectural error. A state machine (SM) determines it's own actions based on it's state and the messages it may receive. The calling code may send messages (information) to a SM. But the calling code shouldn't send actions (imperative commands) to a SM. A SM should b... (more) |
