as.POSIXct sometimes could not convert - format

Please see the following example: some values could not be translated by as.POSIXct
as.POSIXct("2019-03-21T07:51:41.521Z")
as.POSIXct("2019-03-22T05:35:47.824Z")
The first is working, however, the second one did not work what is the difference!

Kibana query doesn't return all relevant logs

I tried to present msg1/msg2 that refer to id13/id22, as shown below:
(message:"msg1" or message:"msg2'") and (Id:13 or Id:22)
The first condition works well, but the second part doesn't - only results referring to id13 return, when there for sure are relevant logs that apply to id22 as well.
Any ideas?

A "display" that always displays in prolog

I have a predicate check(Data,Res) that checksDats according to some rules and returns Res (a function result on Data, assuming Data answers to several criteria).
I have another function generate(N,Data) which generates a N-size Data.
My main program begins with generating many 1-size Data, then if none answered the criteria, we go on to 2-size Data and so on until we reach a certain M upper limit.
main(M):- next_number(N,M), generate(N,Data), check(Data,Res).
However, the program runs for very long time. I wanted to make sure it does not get stuck. For this, I wanted to print the generated Data each time before its being checked. But adding display did not assist, because it only actually displayed if the entire statement was true.
That's not what I want.
I want to keep track of the progran using display, similarly to System.out.println in Java.
Is there any other function that displays anyway? Or an idea how to use display in a way that will always display, regardless if the Data answered the criteria or not?
I thought to do:
(check(Data,Res) -> display(Data);display(Data)).
But I am not sure. Any ideas?
Your long process is likely to be within check - or more precisely, that check fails for most data, causing the system to backtrack repeatedly.
If you display a result in check, you'll have line upon line of tracing. Instead, you could add a write statement to generate, or even to your number generation:
main(M):-
next_number_and_tick(N,M),
generate(N,Data),
check(Data,Res).
next_number_and_tick(N,M) :-
next_number(N,M),
write('Tick - now doing '),
writeln(N).
Upon backtracking, the program will signal the data size it is now working on, giving you an idea of the volume of work it is doing.
The problem in the way you use display is that the entire statement must be true for it to display. Your idea of using "if-then" is good but not accurate. If you want to use it, you should "trick" prolog the following way:
new_check(Data,Res) :- (check(Data,Res) -> display('Victory!'),!; display('Failed Data: '), display(Data), nl, fail).
This way, if the check fails, you will get a report on which Data failed, and if it succeeded everything stops (assuming you want only 1 solution. If you want more, remoce the ! predicate).

Google Sheets/Excel: Checking if a time falls within a range

I'm trying to find a way to see if I can find a way to determine if a time that I stipulate falls between two other times. For example:
Start End
11:33:48 11:53:48
12:20:22 12:38:21
12:39:27 13:00:09
14:16:23 14:20:49
14:20:54 14:22:56
Then, I want to check if a cell (here the value of 12:50 in cell E30) falls between ANY two values in a range in THE SAME ROW. For me, I can get the obvious way to check for this in one row, and this simple version totally works:
=If(AND(E30>A4,E30<B4), "TRUE", "FALSE")
However, I want to check if that number falls within ANY of the values within the ROWS above cells in a range, and I can't get that to work. For example, I tried this and it didn't work:
=If(AND(E30>A:A,E30<B:B), "TRUE", "FALSE")
I also tried a simple countif variation but that didn't do it either:
=COUNTIFS(A:A,">"&E30,B:B,"<"&E30)
Any advice on how to adjust one of these formulas to get it to work?
Try switching the angle brackets around:
=COUNTIFS(A:A,"<"&E30,B:B,">"&E30)
I think this should work for the above data set -
=IF((FILTER(A2:B6, D2>A2:A6,D2<B2:B6)),TRUE,FALSE)
This will give you if there is any match or not.
For the number of rows count that match -
=ROWS((FILTER(A2:B6, D2>A2:A6,D2<B2:B6)))
Alomsot =IF(Q2>R2,IF(AND($X$16>HOUR(Q2),$X$16<(HOUR(R2)+12)),1,0),IF(AND(HOUR($X$14)>=HOUR(Q2),HOUR($X$14)<=HOUR(R2)),1,0))

Report Builder Expressions

Im new to Report Builder and having issues with some expressions that Im trying to implement in a report. I got the standard ones to work however as soon as I try any distinctions, I get error messages. Over the last couple weeks, Ive tried many combinations, read the expression help, google and looking at other questions at internet sites. To reduce my frustrations, I even would jump to other expressions and walk away hoping I would have different insight coming back.
Its probably something simple or something I dont know about writing expressions.
Im hoping that someone can help with these expressions; they are the versions I get the least errors with(usually just expression expected) and show what Im trying to accomplish.
=IIF((Fields!RECORDFLAG.Value)='D',COUNTDISTINCT(Fields!TICKETNUM.Value),0)
=IIF((Fields!TRANSTYPE.Value)='1' and (Fields!RECORDFLAG.VALUE)='A' or
'B',SUM(Fields!DOLLARS.Value),0)
=IIF((Fields!TRANSTYPE.Value)='1' and
(Fields!RECORDFLAG.VALUE)='P',SUM(Fields!DOLLARS.Value),0)
=Sum([DOLLARS] case when [RECORDFLAG]='P' then -1*[DOLLARS])
Thank You.
=IIF((Fields!RECORDFLAG.Value)=”D”,COUNTDISTINCT(Fields!TICK‌​ETNUM.Value))
The error message gives you the answer here - no false part of the iif() has been specified. Use =IIF((Fields!RECORDFLAG.Value)=”D”,COUNTDISTINCT(Fields!TICK‌​ETNUM.Value), 0)
=IIF((Fields!TRANSTYPE.Value)="1" and (Fields!RECORDFLAG.VALUE)="A" or "B",SUM(Fields!DOLLARS.Value),0)
This is not how an OR works in SSRS. Use:
=IIF((Fields!TRANSTYPE.Value)="1" and (Fields!RECORDFLAG.VALUE="A" or Fields!RECORDFLAG.Value = "B"),SUM(Fields!DOLLARS.Value),0)
The 0s are returned due to your report design. countdistinct() is an aggregate function - it's meant to be used on a set of data. However, your iif() is only testing on a per row basis - you're basically saying "if the current row is thing, count all the distinct values" which doesn't make sense. There are a couple of ways forward:
You can count the number of times a certain value occurs in a given condition using a sum(). This is not the same as the countdistinct(), but if you use =sum(iif(Fields!RECORDFLAG.Value = "D", 1, 0)) then you will get the number of times RECORDFLAG is D in that set. Note: this requires the data to be aggregated (so in SSRS, grouped in a tablix).
You can use custom code to count distinct values in a set. See https://itsalocke.com/aggregate-on-a-lookup-in-ssrs/. You can apply this even if you have only one dataset - just reference the same one twice.
You can change the way your report works. You can group on Fields!RECORDFLAG.Value and filter the group to where Fields!RECORDFLAG.Value = "D". Then in your textbox, use =countdistinct(Fields!TICKETNUM.Value) to get the distinct values for TICKETNUM when RECORDFLAG is D.

The "getnodevalue" of HTMLUNIT not working on domattr

every time i want to get the Value of my DomAttr i get an TypeError:
My Code:
Wanted = page.getByXPath("//span[contains(.,'Some')]/parent::a/#href");
return this
[DomAttr[name=href value=URLSTRING]]
Now i want to geht the value (=URLSTRING) with Wanted.getNodeName();
but every Time i get the Error
Cannot find function getNodeValue in object [DomAttr[name=href value=
same when i use getValue
please help me
There are some things that make no sense in the code (particularly, because it is not complete). However, I think I can guess what the issue is.
getByXPath is actually returning a List (funny thing you missed the part of the code in which you specify it as a list and replaced it with a Wanted).
Note you should probably also have type warnings in the code too.
Now, you can see that the returned value is in square brackets. That means it is a List (confirming first assumption).
Finally, although you happened to miss that part of the code too, I guess you are directly applying the getValue to the list instead of the DomAttr elements in the list.
How to solve it: If you need more than 1 result iterate over the elements of the list (that Wanted word over there). If you need 1 result then user the getFirstByXPath method.
Were my guesses right?
