hack | The tiniest web-framework

I've had trouble articulating a simple way to break this question down in to a question title, and therefore a google search.

I'm wondering if there is a sorting algorithm already defined that can sort an array of numbers without keeping pairs adjacent. Easier to explain with an example:

Values:

1,3,5,2,1,3,2,4

A normal numerical sort would come out as:

1,1,2,2,3,3,4,5

What I would like:

1,2,3,4,5,1,2,3

I could hack this together, I just want to know if there is a name for this kind of sort.

Im trying to make a generic instance mapper from an SQLite DB to my project logic layer. Each entry in the mapper is an instance of some class "DAL< name >" for example DALProduct all in the same package that extends class DALObject with the following structure:

One thing which I have learnt from working with Identity Server is that, out of the box, ASP.NET Core Identity does not play too well with Identity Server. Refer to this question.

ASP.NET Identity contains a way of ejecting users where a particular user's data has changed. This is regulated by the SecurityStamp column of the aspnetuser table. When the stamp changes, the next time the cookie is validated, it fails validation.

This is turned on by default and it is the reason why it does not work well with Identity Server.
You end up with users getting kicked out erratically. And when you expect it to kick users out, it doesn't.

Anyhow, how do you disable this feature of ASP.NET Identity???

There is a column on the UserManager called SupportsUserSecurityStamp. However, it is a "getter" only and I cannot find any configuration setting for switching that to return false.

It seems to me that the only way is to derive from the UserManager class and make that property only ever return false.

That feels like a hack. Especially when you look at the code for that property on Github:

I have a login service component which has a behavioral subject _loginEmailId" and the method updateLoginEmailId(email:string)` to update its value as following.

This question was previously posted as SO#67861846. But someone (non-moderator) marked it as a duplicate and closed it. It is NOT a duplicate as claimed: getResponseCode WAS indeed called but the result was no help (always 200 even for an invalid host). So, I try again...

The Question

My app regularly downloads files from a server using HttpUrlConnection(). Brief code example below:

Given a rational number, I need to get the nearest integer, with exact halves rounded up (that is, towards positive infinity). The results must be exact, which rules out float and Decimal, both of which have finite precision.

The following code works perfectly in all cases except for negative numbers:

I'm refactoring code and wonder if this is possible.

I am currently preparing html slides for an R modelling workshop, for which I use the awesome xaringan package for R. It is based on remark.js. Compared to ioslides and slidy, it does much better suit my expectations. I am absolutely excited! One feature that I missed, are scrollable "long slides". Here I leave of course the "slides" paradigm towards a mix between slides and ordinary web pages, but I find this didactically attractive to explain complex content and code. This style worked well with slidy, and I found also some hints how to enable scrollable code in xaringan.

Here I use the following CSS (found in a related post at SO):

Whenever I fetch data from any server to display it in ag-grid, ag-grid does not maintain the column order for the column that uses valueGetter to choose the value and puts that column automatically at the end.

The problem is replicated in the following code sandbox link: https://codesandbox.io/s/ag-grid-column-ordering-bug-bz055 as a minimum reproducible example

The data received from the server is in the following format
