I wrote this HTML sanitizer for use in web scraping. The idea is to safely copy content from a site but apply my own style-sheet and remove any unsafe elements. This whitelist approach seems very d...
There are multiple questions/aspects in your posts, so I will go one by one: Stack Overflow which answers many questions While this is true, for many questions SO has an important drawback. I...
That's nice that you're provided your attempts but, as it was already mentioned in comments, it would be better to show us all the parts. Again, if you're not sure how to write it properly in C# th...
The standard for multi-line text input is to use a textarea. Don't use input type="text", it won't work. I'm not sure why you don't want to use a textarea, but after reading this answer, I hope you...
According to this answer, Codidact uses highlight.js for syntax highlight, and "support whatever languages are enabled by default in that package". And according to this table (in highlight.js Git...
While learning JavaScript, I started to see sometimes the <script> is placed in the <head> and sometimes it is placed in the <body>, What's difference between placing the <scri...
Assignment = = is the assignment operator. There's nothing much to say here. Abstract Equality == == is abstract equality - it will attempt to perform a type conversion before evaluating equalit...
Short version As you probably know SO offers Stack Overflow for Teams as a product for a knowledge management tool for private use (private teams). I am wondering if it is possible for Codidact t...
The problem Given a string s containing just the characters '(', ')', '{', '}', '[' and ']', determine if the input string is valid. An input string is valid if: Open brackets are closed by ...
A simple way to deal with this is flex, wrap your 3 columns in a flex container: <div class="container"> <div class="formField"></div> <div class="formField"><...
First of all, we need to understand what a JavaScript Date actually is. And surprisingly, it's not exactly a date (at least not in terms of having unique values for day, month, year, hour, minute a...
Our web site has a widget that displays some date-based information that we retrieve from some JSON-formatted data (one object per date). We get the current date from the environment, possibly adj...
Power Users has just been launched and I remember that Software Development has some content related to office suite usage (example). Is it OK to migrate these questions to the Power Users communi...
You should know I am not a bot by now ;-)
Context Our team has begun migrating a pretty old internal application and one aspect that got my attention is the impersonation. This is implemented as follows: only administrators are allowed...
We have a bunch of dead branches in our git repository, and I'd like to clean them up. Ones that were merged (but not deleted at the time) are easy; we can see those in the branch list on Bitbucke...
From the command line, the following command will give you a list of all authors who have made local-only commits to a branch some-branch: git log some-branch --not --remotes --format="%an" And...
This behaviour is documented here: "... an ambiguous timestamp that could fall on either side of a jump-back transition is assigned the UTC offset that prevailed just after the transition." S...

I recently encountered a strange situation in javascript; if I have: let obj = { a: function() { return (this === obj) ? this.b : 'bye'; }, b: 'hello' }; I can call obj.a with this bound...
There is no fixed number of days in a MONTH interval. DATE_SUB is mostly just decrementing the number in the months position of the date provided. So DATE_SUB('2020-09-14', INTERVAL 3 MONTH) is '20...
I often find it useful to arrange things so that each commit on master's first-parent is a discrete change. It allows git log --first-parent --oneline to be used as a concise, automatically-generat...
This looks like it's a slightly restricted version of the circular dilation minimization problem in the theory of graph drawing. See, for example, https://doi.org/10.1080/00207168808803629. Specif...
