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...

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.

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) |

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) |

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: 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...

A: Are general questions (hopefully resulting in comprehensive, 'canonical' answers) in scope I think that questions about programming paradigms fall under the umbrella of "questions about software design or software architecture" and are thus on topic. There have also been several questions about OOP that remain open, including a very conceptual one. Granted, that last question met with a... (more) |

A: Retrieve user details from service in Angular There are quite a few bugs there :-) Let's start with with the big one: In Angular (and most client side web frameworks) requests to the server happen asynchronously. That is, when a method does an http call, the method doesn't wait for the response, but continues immediately. So when you do... (more) |

A: What are the disadvantages of using static methods in Java? If it were always better to use `static`, the language would have been designed to always assume `static`, or at least default to `static`. That the language defaults to making methods not static indicates that the designers of the programming language envisioned static methods to be rare. Java is... (more) |

A: What's the correct way to merge a branch and its dependent branch back to master? > I think a branch is a set of commits and a commit is a set of deltas, so my concern is that merging feature-B to master would reflect only the work that is unique to feature-B Not quite: a branch is a pointer to the state of a repository at a particular point in time (as represented by the commi...

A: Mixing "operational" database models with archiving ones in the database context Generally speaking, switching data access technologies to avoid a naming conflict seems overkill.

A: What are the risks of using iFrame as a temporary migration step for an internal web application? I think a lot of the bad press about iframes stems from W3C deprecating them in HTML 4 strict mode, which caused the herd of web developers to internalize that iframes are bad and should be avoided. However, this deprecation was due to accessibility concerns that have long since been resolved, an... (more) |

A: Dye all label asterisks Red with vanilla JavaScript In HTML, style information is applied to elements; it can't be applied to individual characters in a text node. Therefore, if you want to style the `` differently, it needs a dedicated element. You can use a pseudo element for that, but since an element can't have two after pseudo elements, you c... (more) |

A: Is it necessary for a build server to remove node_modules before an AOT build? I suspect this is an outdated practice: Prior to npm 3, npm did not keep track of resolved dependencies, and npm install would try to reconcile the existing with the declared dependencies. Since `nodemodules` is not commonly under version control, this meant that the build would depend on hidden s... (more) |

A: Is omitting braces for single statements bad practice? Advantages of Mandatory Braces When in Rome, do as the Romans do.

A: The size of the code format window is much too small. Seconded.

I know of no code editor that uses an increased line height? I'd therefore consider both increasing t... (more) |
