kandi X-RAY | qux Summary

qux is a R library. qux has no bugs, it has no vulnerabilities and it has low support. However qux has a Non-SPDX License. You can download it from GitHub.

Demo R package. Shows how to call R from C using either. Note the latter is deprecated since R-2.15.0 but still works (at least for a while). Also shows how to call R from Fortran (via C function pretending to be Fortran subroutine). This package when checked with. generates complaints about registration of native routines. If we actually wanted to make this a CRAN package (which of course we don't because it is just a demo), we would need to do that. See R package fooRegister in Github repo foo (for how to do that.

Inner join two `HashMap`s in Rust

Asked 2021-Jun-06 at 01:58

Suppose we have two std::collections::HashMap-s, say HashMap and HashMap, and a function Fn(V1, V2) -> R.

How do I perform an inner join on these hashmaps so that I get HashMap on their shared keys as a result? Here's a reference implementation to illustrate what I mean:

...

ANSWER

Answered 2021-Jun-06 at 01:58

As the answer you linked mentions, for a hash table, which does not have an inherent ordering, there is no way to do this more efficiently. (Using the hash codes of the objects do not help, because unless you've used an alternate hasher, every HashMap uses a different hash function, to prevent denial-of-service attacks which submit deliberately colliding hash keys.)

There is one high-level improvement you can make to the algorithm: iterate over the smaller of the two hash tables, since that requires the fewest lookups.

If you have a sorted collection, such as a BTreeMap, then itertools::Itertools::merge_join_by can help you implement a merge of sorted data:

QUESTION

Django queryset matching null value with null OuterRef

Asked 2021-Jun-01 at 06:26

In Django, I'm trying to filter Foo objects by whether a Bar object exists with the same values. The code I have below works fine for non-null values. But I also want it to return true if Foo.baz and Bar.baz are both null.

...

ANSWER

Answered 2021-Jun-01 at 06:26

You can annotate the value of OuterRef('baz') and use that in your filters. Since you need to perform OR conditions you would need to use Q objects [Django docs]. Also it looks like filtering on the annotated OuterRef will not work because of this bug having Ticket #31714, but we can get around that by using an ExpressionWrapper to manually specify the output_field. Hence if baz is an IntegerField your query would look like:

So you might be running into CORS issues.

You need to enable CORS in the API Gateway, and then you need to also include CORS headers in the response from your API Gateway Response. (including it in the actual response is often overlooked, so make sure you do that)

QUESTION

Creating a JS function and specifying its scope?

Asked 2021-Apr-19 at 00:56

I had a random, rather rudimentary question pop into my head as I was writing some JS about scopes and closures. (Please bear with me with the rather convoluted example.)

Let's say I have two functions, one that's more or less a decorator called "makeMagicFn". This thing takes in an object, looks up the randomFn method on it, and does something cool to it, attaching it as a property to a new object as someSpecialFn, returning the object.

The second function is where that magic happens. It has a few local variables inside of it, and then defines the "random" function for use in the makeMagicFn described above.

Here's the fun part. The randomFn, defined here as innerFn, looks up the variables defined on outerFn's scope (foo and baz), and does some stuff with them. At the end, the decorated innerFn is returned from outerFn to be used by its caller.

...

ANSWER

Answered 2021-Apr-19 at 00:56

No, this is not possible. Local variables are local, and scope is lexical. To create a closure over them, you must define the function where they are in scope.

You can do lots of trickery if you don't make foo and baz local variables but properties of an object, which you then can pass around (in the easiest case, as an argument to makeMagicFn).
