Great answer! Although, if i am picky (and a bit of an ar*ehole) i think you took the challenge away from Derrick, now he needs to find himself another one :-) I also think a mention of "[rubber duck debugging](https://www.thoughtfulcode.com/rubber-duck-debugging-psychology/)" would apply to the situ...

Yeah, my false perception of an outlier due to me not noticing the E notation led me to a misbelief that the test functions where only executed once. Guess i need some shut-eye... (more) |

@hkotsubo oops, i have to admit i didn't notice the scientific notation. My bad, i am sorry... :-) (more) |

To ameliorate such effects of uncontrolled disturbing runtime effects and get "better" numbers without resorting to a full benchmark suite, run each individual test at least a couple hundred/thousand times and average the execution time. Also, prealloacte the stack to a size of len(s)/2 and performan... (more) |

Your numbers don't appear to be "clean". Look at the "Unbalanced in the beginning" test. How could "is_balanced(s)" take more than 1 sec? Of course, it did. But this is not the performance characteristic of the alogrithm but rather some "disturbance" in your runtime environment. In a clean runtime en... (more) |

A: Detecting balanced parentheses in Python Use a stack while just scanning your string once from left to right. No need for multiple (performance-wise) expensive string replacements. If implemented right, the stack will only ever contain at maximum `len(s)/2` elements. The algorithm is rather straightforward: Check first whether the str... (more) |

This approach is not going to work (i am still curious about an alternative solution someone might come up with, though). From the doc about generated cols https://dev.mysql.com/doc/refman/8.0/en/create-table-generated-columns.html, first paragraph: "_Values of a generated column are computed from an... (more) |

A: Validate All Object Properties with JSON Schema If the names of the properties in the jobs and people objects are variable, you can use the `patternProperties` keyword instead of the `properties` keyword in the respective schemas for jobs and people. As per specification for `patternProperties` (https://json-schema.org/draft/2020-12/json-schema... (more) |

If your identifiers have to satisfy some specification wrt to format and/or allowed characters, you might construct the regex pattern(s) in way that they match the specification, and additionally employ the "additionalProperties" keyword that uses the "false" schema to fail validation if any properti...

Just a rough idea from the top of my head (untested, unverified, might be bogus). You could perhaps use the "patternProperties" keyword, with which you would specify a regex pattern against which property names are being matched. Since in your case the property names in "jobs" and "people" don't matt... (more) |

You have defined `dir="rtl"` in your `<form>` element. Note how the comboboxes in the background of your screenshot are mirrored compared to LTR. So, i would naturally expect the radiobuttions also adhere to this directive. Since radiobuttons are normally **in front** of a text label, for RTL this wo... (more) |

To clarify, if you would suffer from a left-to-right vs. right-to-left issue, you would have a problem with the direction of the text flow, where for example "אבחון קידום אתרים" (text direction being RTL/right-to-left) would be incorrectly displayed as "םירתא םודיק ןוחבא" (text direction being LTR/le...

Uh, the text in your screenshot is right-to-left, no? I don't know Hebrew, but "אבחון קידום אתרים" translates to "SEO Diagnosis", and "שיווק באמצעות תוכן" to "Content Marketing" or something similar (based on Google Translate and Wikipedia). It feels to me your actual concern/problem seems to be rath... (more) |

Side note: The `type` variable looks exceptionally fishy to me. Where is it set to a non-null value? What are conf_verify_key and parse_file _really_ doing with the `type` variable used as one of their function parameters, especially when its value is `null`? Since i don't know anything about those, ... (more) |

"Am I missing something?" Who knows. Use a step debugger and step through your code. This should make it easier to encircle the code line that causes the seg fault. Also watch any variable used in the function that you suspect is crashing (parse_group?), and see whether the vars have the expected val... (more) |

Side note: If you can't diagnose/solve the problem, i suggest seeking help in a mysql/Manjaro/Arch forum that's better suited for a back-and-forth discussion. Trying to troubleshoot system configuration problems based on a brief description in a Q&A format is rather limiting and cumbersome, as in man... (more) |

| Comment | Post #282033 |
It feels like the mysql server isn't running. Trying to use the `service` command will not succeed, because Manjaro is based on Arch, and Arch does not have the `service`, but rather the `systemctl` command (in other words, systemd). Thus, try (re)starting mysql by using the `systemctl` command. Be a... (more) |
