A: Delete all occurrences of a character in a webpage with vanilla JavaScript With the help of a little recursion, it's straightforward to go through all text nodes and replace their contents: ``` function replaceIn(e) { if (e.nodeType == Node.TEXTNODE) { e.nodeValue = e.nodeValue.replaceAll("a", ""); } else { for (const child of e.childNodes) { repl...

In this case, the image was actually helpful because it revealed that OP was invoking the compiler by hand rather than using the built in eclipse compiler. (more) |

A: Java cannot find class within same package eclipse has a built-in compiler. When developping in eclipse (or any other Java IDE), you can run from eclipse, you can package as a JAR file from eclipse, and even run a full fledged maven / gradle build from eclipse. There is no need to ever run javac by hand when you have a Java IDE. One reason... (more) |

A: Mocking methods with arguments You mean, aside from giving the team that made `B` a stern talking to? ;-) You could introduce another layer of indirection, and mock that. For instance like this: interface MockFriendlyB { public void add(T arg); } class UnmockedB implements MockFriendlyB {... (more) |

Well, I'd prefer:
```
assertEquals(13, fun(42).getY());
assertEquals(10, fun(43).getY());
assertEquals(16, fun(44).getY());
assertEquals(133, fun(47).getZ());
assertEquals(1, fun(3).getZ());
assertEquals(16, fun(2).getZ());
```
which makes it way more obvious that the blocks invoke dif... (more) |

A: How to create an object, call one of it's methods and pass it as an argument as a oneliner? It seems to me that you are hobbling yourself by making design constraints more absolute than they need to be. For instance: You don't want to change the code under test, not even a tiny little bit. You don't want to introduce a helper function, because helper functions clutter the code (is tha... (more) |

A: Best practices in setting up a development & production environments As a baseline, here's what we did in my last company: For tests, we used an in-memory database, whose schema was initialized by our object-relational mapper, with initial data loaded either from an SQL-Script, or code using the O/R-Mapper. Before deploying, we would generate SQL-Scripts for mig... (more) |

I guessed that this was the reason you mentioned onbeforeunload :-) Just to be perfectly clear, the problem I see is that network I/O in onbeforeunload can not be relied on to work, because the application will likely unload before the server response arrives, making it impossible to react to a failu...

In the Schwartzian transform, I'd prefer using an object to hold the tuple rather than arrays for better readability (i.e. one can then write `sort((a,b) => a.sortKey - b.sortKey)` rather than using "magic index 1". Also, your conclusion makes it sound as if execution speed were the only concern. It ... (more) |

That last question might be specific enough to be answered in a reasonable amount of text (this answer is gonna be: it depends, and would have to enumerate the various things that usually factor into this decision). The question you originally posted is bit too broad IMHO. You may therefore want to e... (more) |

A: Detecting if a user has stopped interacting with a web view for a certain time The weakness of responding to idle state is that the app might be closed before the idle state is reached, and that a closing app might no longer be able to communicate with the outside world. Saving to local storage rather than remote systems may therefore be more robust and cheaper, allowing more f... (more) |

Well, the difference is that the databases will be separate databases. Can you clarify what you mean with "set up"? Installing the database software (off topic here), migrating schemas, configuring a different database connection in test and production, or something else? (more) |

A: How to prevent token from being refreshed It's worth noting that logging out a user goes way beyond not fetching a token, because your UI needs to inform the user he is about to be (or has been) logged out. And if your UI closes or locks itself, it probably doesn't matter if it has a current token. So I'd handle this fully in the UI; for ... (more) |

A: Can I set a memory limit for the .NET Core garbage collector to collect objects more aggressively?

I see. Knowing that you are concerned about peak memory use, rather than, say, the length of garbage collector pauses helps writing targeted answers. (more) |

A: Using nested paths vs. flat ones for API resources Actually, while REST mandates a great many things, it does not constrain the structure of URLs. To wit: The paper that coined the term "REST" describes resource identifiers as black boxes, and makes no reference to their internal structure. In fact, if we take a strict reading of the REST architectur... (more) |

A: Regarding the heap sort algorithm. As you know, a max heap is a binary tree such that each parent is greater than its children. The most compact and efficient way to represent such a tree is an array, where each index corresponds to a node in the tree, numbered from the root, level by level, from left to right, as shown in the foll...
