Python allows for operators to be overloaded (the subject of a separate future Q&A). The / operator doesn't strictly mean division in a mathematical sense; it means whatever the operands define...
Mac/Linux In this environment, Python scripts can be given a shebang line that tells the operating system that the file is a script, and what interpreter (i.e., Python) to use for it. Because # st...
This probably makes for a thoroughly unsatisfying answer, but there's probably far stronger cultural pressure than technical pressure. In European-derived cultures, we mostly group numbers by powe...
You could use fgets to read from STDIN. And to print the message, just use the short tag (<?= whatever, which is a shorthand to <?php echo whatever; ?>): <?='Hello, '.fgets(STDIN).'!'...
I wouldn't. Not unless you intend to keep developing on every branch independently! Presumably you're not doing that. In that case, I think it makes your intent clearer to just use a tag to mark t...
As you're using userscripts, I'm assuming this code is supposed to run in a browser. Hence, you could download the scripts and add its contents to the page's DOM (by using a script element). For t...
I've seen that recently two requests to add syntax highlight to some languages were deferred (this and this). According to the status-deferred tag description: "the requested feature will not be i...
While I tend to agree with @Alexei that reading from the standard input is quite a common issue I also think that console.readline tag is too narrow and therefore it shouldn't exists. On the other...
Proposal: Can Include A link to a chat room related to the question or answer. Even if tangentially. I've always found SO to be too dry. Sure, pleasantries are as helpful in a question o...
Currently, Java 16 is the latest version, and there's no support to branch reset yet. But one - still far from ideal - alternative is to use lookarounds: Pattern pattern = Pattern.compile("([aeiou...
You've got an inefficiency in your code, as you always do replacements 3/2 times the length of the string. That is unnecessarily expensive. By instead testing in each iteration whether the length ...
What's the better way to store base64 in SQLite Database? I was thinking to put base64 as TEXT since base64 has lots of chars. CREATE TABLE name (id INTEGER PRIMARY KEY AUTO_INCREMENT, image TEXT)...
I am guessing a little here. By not preventingdefault, the form will POST the data to the server. If you switch to AJAX you have to provide the body as per documentation. However, I do not rememb...
This is weird: I tried to edit the tags on your post to see if I could reproduce it, and the editor showed the C++ tag there even though the post did not show it. I deleted and re-added it and sav...
I edited the tags of my very first Codidact question: https://software.codidact.com/posts/281486 Someone proposed the "python" tag. Since I am working with C++, I removed the "multithreading" tag...
I am fairly new to working with @ngrx pattern in Angular which is a state management pattern relying on Reactive Extensions. One of the convenient structures is @ngrx/entity which helps with manag...
Actually, TypeScript is perfectly able to type check the code you posted. Here's what the compiler thinks: const functionName = disable ? "disable" : "enable"; // inferred type: "disable" | "enabl...
Estela's answer provides great insight about how to do it also in SQL Server. Unfortunately, there does not seem to be a build-in array functionality, so one way is to rely on strings as shown here...
For small tables you can bound the recursion depth: WITH my_cte(childId, parentId, depth, max_depth) AS ( SELECT r.childId, r.parentId, 1, (SELECT COUNT(*) FROM My_Table) FROM My_Table ...
I was reading the Wiki of Decibel. Unfortunately, I "forgot" there's different between amplitude ratio and dB level. After reading the wiki. When I looked at my source code, I saw sounddB was unuse...
I know I can change the font of each cell individually by overriding getCellRenderer(row, col) in JTable but I want to be able to change the font of an entire column at once and, ideally, have the ...
A shared hosting based Apache PCRE public_html/.htaccess file for a website with the common features: MediaWiki based (most of the website interaction is backendish --- there barely are any fron...
I have an array friends = Array.new friends[0] = "Mad man" friends[1] = "hey" There's two ways to print it (using print or puts). At first I tried print print friends which gave: ["Mad...
but I don't think I can count on that working There really doesn't seem to be a ready-to-use way to get that message (which feels like a good feature-request). While ex.args[0].args[-1] is in...
I had build an application using following source code (following the steps). package com.decibal.level; import androidx.appcompat.app.AppCompatActivity; import android.media.MediaRecorder; ...
