QUESTION
I'm trying to narrow a union type using a conditional type definition but no matter how hard I try I can't comprehend why this code is failing :
...ANSWER
Answered 2021-Dec-28 at 14:07The problem is that handler (ignoring the undefined, i.e. within the if block),
is either a map EventA => Void or a map EventB => Void, whereas the input ev is either of type EventA or EventB. So from the compiler's perspective, it could be, for example, that handler is of type EventA => Promise, while ev is of type EventB, which then are not compatible. The type FindByTag does not reify an AnyEvent to an actual EventA or an EventB based on what K is.

QUESTION
I'm trying to summarize a dataset by groups, to have dummy columns for whether each group's values appear among the data's ungrouped most frequent values.
As an example, let's take flights data from nycflights13.
ANSWER
Answered 2021-Nov-04 at 23:24Does this do what you want? As far as I can tell it matches your output but has more rows because it includes all months for all carriers; carrier "OO" only has flights in 5 months and your version only shows those 5 months in the summary.
With the data as provided (336k rows), this takes a similar amount of time as your function, but it's faster as you deal with larger data. When I run these on data 100x as big after setting my_flights_raw <- my_flights_raw %>% tidyr::uncount(100), to make it 33M rows, the code below is about 40% faster.
Given the large number of groups you're dealing with, I expect this is a situation where data.table will really shine with better performance.

Target: To give margin of upto 8cm to a dynamically generated pdf, which has repeated header and footer on every page.
Current issue: Although I am able to give margin to the pdf and the content gets properly aligned on the first page, but from the second page onwards the content of the body starts to overlap with the header of the page,
Page 2 and beyond - ISSUE
What I tried: Tried the solution in related questions like :- Content overlapping with header on second page of PDF and Table headers overlapping on second page when printing/PDF and other ones too, but none of them seem to be working.
Code:-
...ANSWER
Answered 2021-Jun-28 at 14:04The main issue seems to be that you placed your "Main content" in one single row.
I managed to make it work doing something similar to this.
Also I moved the header and footer placeholders to thead and tfoot respectively.
Additionally, the "@page{margin: 5cm;}" seems to break it, to be honest I don't know why.
I had to modify the code quite a bit but I hope it helps you as a template for what you want to achieve.
This is the code I ended up with:
QUESTION
Why this code won't compile? Tested on Scala 2.13.6. Is there a way to let scalac know that SizeOfType[Unit]#Size is actually Short?
ANSWER
Answered 2021-Jun-05 at 19:38No, there is no way.
Think about what would happen if you call test with another implicit value of type SizeOfType[Unit] which defines type Size = Int.
Or said differently, the method test can only infer types based on the trait definition of SizeOfType, not on one actual implicit value content.
You could however define test as returning the type ev.Size.
QUESTION
Why is f-bounded polymorphism in Scala commonly implemented with an upper type bound as well as a self type like
...ANSWER
Answered 2021-May-24 at 13:43So, the idea of trait MyTrait[A <: MyTrait[A]] { self: A => ... } is to force A to be the type of the current implementation.
If you omit the upper bound, then, aside from Foo not being able to do very much with its type parameter (it knows nothing about its members), you can also do things like this, which is not very useful.

Install ev
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
