A: WPF MVVM ListBox not updating `List` is not observable. In other words, `List` does not offer a mechanism through which it could signal that its content has changed. If it is possible/permissible to modify the Demo class, then use `ObservableCollection`, `BindingList` or something similar instead. As their type names suggests,... (more) |

I second hkotsubo's opinion. For additional information about how the javac compiler looks for types (or their respective source files), see the official Java compiler documentation: https://docs.oracle.com/en/java/javase/18/docs/specs/man/javac.html#searching-for-module-package-and-type-declarations...

Okay, if you are interfacing with an AD service, i would suggest to go with what the https://ldapwiki.com/wiki/SamAccountName page says.

What exactly do you mean with "_test this separately_"? If the intention is to just test the private function _foo_ in isolation and independently from _bar_, you might want to check whether some of the suggestions given here might work for you: https://softwareengineering.stackexchange.com/questions...

Relocate your server-related I/O into its own service with an API defined through an interface or such.

The question you have to answer yourself is: What do you really want to test here? Do you actually want to test the behavior of the server? If so, why are you trying to test _foo_? Or do you rather want -- as your question states -- to test the behavior of your code? If that's the case, why would you... (more) |

Look at the "LDAP: Schema for User Applications" [RFC-4915](https://datatracker.ietf.org/doc/html/rfc4519#section-2.39).

@#8176

@#8176 i guess this could be a matter of refactoring support offered by IDEs.

@#8196, thanks for adding a footnote to your question text that contextualizes where you see the reduction of code duplication. Otherwise, in a general sense there would still be no reduction in code duplication, because changing the variable name instead of the type identifier would also require thr... (more) |

As an advantage of `malloc(n * sizeof *p)`, i would consider the locality (in terms of location in the source code) of the identifiers used in `p = malloc(n * sizeof *p);`, thus potentially reducing the chance of coding mistakes when a function declares a number of pointers (or a program when global/...

With
```
int *p;
p = malloc(n * sizeof(int));
```
the type identifier ("int") is being duplicated, thus one duplicated token.

Yeah. In my comments, i was focusing only on the question which was about switch-case compound statements used as value mapping/translation as part of C# code.
Of course, if value translation/mapping needs to be configurable or extensible, or otherwi... (more) |

Then remove the `checked` keyword from the `GetSumChecked` method:
```C#
[MethodImpl(MethodImplOptions.NoInlining)]
private static int GetSumChecked(int[] numbers)
=> numbers[0] + numbers[1] + numbers[2];
```
and run the benchmark again. (Now it should be apparent why i suggest separate Ge... (more) |

| Comment | Post #285839 |
To do so, the benchmarks should be altered so that the code for the checked and unchecked case is isolated into separate methods. Keeping as much of your current code base as possible, i would do this (not sure if you need to add `[MethodImpl(MethodImplOptions.NoInlining)]` to prevent inlining, but d... (more) |

Just a stupid idea: What if the observed results are not due to the use of _checked_, but an artifact of the JIT compiler or due to external factors influencing your benchmark run (like, do you have other stuff running on your box that might possibly intermittently load the CPU and chew cycles)?

Generally, if a switch compound statement only serves to translate/map values, replace it with a switch expression.
If the case branches feature side-effects (some other code besides returning a value), either keep it a switch compound statement or refactor it into a switch expression with the cas... (more) |

Just an idea... What happens if you don't put the Hebrew character literal in the javascript code, but instead use its character code, i.e.:

event.key === '\u05DA' // final kaf

or

event.key === '\u05DB' // kaf

Yes, memory-mapped I/O is the only way to do it with standard-conform C in a freestanding implementation, and typically involving `volatile` -qualified types.

Again incorrect. Memory-mapped I/O can be done entirely in C without needing language extensions nor code modules written in other languages. Depending on the actual architecture or specific... (more) |
