Spark for some reason doesn't distinguish your c1 and c2 columns correctly. This is the fix for df3 to have your expected result:

The problem is that Congo_DMA_2$Cluster must be a factor, not a character vector. Older versions of R made this conversion automatically when creating a data frame, but the current versions do not. Just add the following line to your code after creating Congo_DMA_2:

because map and forEach methods don't handle the asynchronous function you passed in an async await way.

When you check the polyfill of both method, you'll find a line like this callback.call(T, kValue, k, O);. So, basically, it just execute the callback. If the callback is an asynchronous method, it doesn't wait its execution to be done. Instead, it continue executing other codes.

So, when you save your array of data to database, your callbacks inside map & forEach just issue a few query, the final order of database's execution may be uncertain.

You're right to be confused by this example. With a range of 4..5, the guess (midVal) would be 4. The only way the line of code GuessNumber(lowVal, midVal-1); would be executed is if the user answered "low" which is:

1. a lie, or
2. their number is out of range.

The example code doesn't account for search values outside the initial input range, which a binary search should do.

The most likely cause is that the global modules installation directory is not in your path. As a quick workaround, you can run it like this:

Is this true in all cases, or can more intricate examples be constructed where unification would still recurse infinitely?

AFAIK no.

I can't recall seeing where =/2 did not work as expected. Granted my expectations are of how SWI-Prolog does =/2 as noted below.

As a related side-question, why does (again, I used swi-prolog) unification binds X to Y in the following example? I didn't expect that.

See these comments in the SWI-Prolog C code for cyclic terms.

where can we at least look at all possible things like that?

Aiui the source code of the Rakudo compiler is as good as you're gonna get.

It looks to me like EXPORTHOW is processed here, with DECLARE in particular here, as part of World.nqp.

Afaik the World class is:

• An internal implementation specific detail of Rakudo. It is not part of the Raku language. It is not something you can rely on. It is not officially supported.

• Written in nqp. nqp is not Raku. It's essentially a small subset of Raku focused on being a good programming language for writing compilers.

In short, yes, it's legal.

The concept of an identifier is a syntactic one: when parsing Raku, the parser needs to classify the things it sees, and the identifier rules indicate what sequences of characters should be recognized as an identifier.

By contrast, stashes, method tables, and lexical scopes are ultimately hash-like data structures: they map string keys into stored values. Just as there's no limit on what keys one can put into a hash, there's not one here either. Given meta-objects can be user-defined, it's unclear one could reliably enforce limits, even if it was considered desirable.

The ::(...) indirect name syntax in declarative contexts comes only with the restriction that what you put there must be a compile-time constant. So far as parsing goes, what comes inside of the parentheses is an expression. The compiler wants to get a string that it can use to install a symbol somewhere; with identifiers it comes directly from the program source text, and with indirect name syntax by evaluating the constant that is found there. In either case, it's used to make an entry in a symbol table, and those don't care, and thus between the two, you have a way to get symbol table entries that don't have identifier syntax.

I'm afraid you just have to put up with the vulnerabilities. Angular has a very strict set of dependencies, and in changing the versions of those dependencies you've broken your app.

Make sure you keep updating your Angular project as often as is feasible, as the Angular team regularly update Angular's dependencies to mitigate these issues.
