kandi X-RAY | foo Summary

foo is a R library typically used in Testing, Mock applications. foo has no bugs, it has no vulnerabilities and it has low support. However foo has a Non-SPDX License. You can download it from GitHub.

r package foo is a toy r package to serve as an example for statistical confusing classes. (actually now two packages, see the end of this readme.). it illustrates calling c or fortran from r. each function that calls c from r needs both the c function and an r function that calls it (so users don't have to know about this). to illustrate this we have an r function foo (package/foo/r/foo.r) that calls either c or fortran depending on an optional argument type. the functions that it calls are. all of these functions do the same completely boring task (squaring the elements of a vector). the point is just to show computation moving from r to c and back. this package also illustrates using the r uniform and nonuniform random number generators inside c or fortran called from r. again all three interfaces are illustrated. the fortran one is a bit tricky because there is no r fortran api for calling the random number generators, so we write stub c functions that look like fortran functions to fortran (a c function fred called from fortran must be wrapped with a macro f77_sub(fred), see section 6.6 of the book writing r

The difference in behaviour can be accounted for by this behaviour, described in (for instance) the following note in ECMAScript 2022 Language Specification sect 14.3.2.1:

NOTE: If a VariableDeclaration is nested within a with statement and the BindingIdentifier in the VariableDeclaration is the same as a property name of the binding object of the with statement's object Environment Record, then step 5 will assign value to the property instead of assigning to the VariableEnvironment binding of the Identifier.

In the first case:

How do I use a Transaction in a Reactive Flow in Spring Integration?

Asked 2021-Jun-15 at 18:32

I am querying a database for an item using R2DBC and Spring Integration. I want to extend the transaction boundary a bit to include a handler - if the handler fails I want to roll back the database operation. But I'm having difficulty even establishing transactionality explicitly in my integration flow. The flow is defined as

Well, it's indeed not possible that declarative way since we don't have hook for injecting to the reactive type in the middle on that level.

Try to look into a TransactionalOperator and its usage from the Java DSL's fluxTransform():

QUESTION

Postgres: Count multiple events for distinct dates

Asked 2021-Jun-15 at 17:04

People of Stack Overflow!

Thanks for taking the time to read this question. What I am trying to accomplish is to pivot some data all from just one table. The original table has multiple datetime entries of specific events (e.g. when the customer was added add_time and when the customer was lost lost_time). This is one part of two rows of the deals table:

id add_time last_mail_time lost_time 5 2020-03-24 09:29:24 2020-04-03 13:20:29 NULL 310 2020-03-24 09:29:24 NULL 2020-04-03 13:20:29

I want to create a view of this table. A view that has one row for each distinct date and counts the number of events at this specific time.

This is the goal (times do not match with the example!):

I have working code, like this:

You can use a lateral join to unpivot and then aggregate:

Return pointer to flatbuffer from a method

...

ANSWER

Answered 2021-Jun-14 at 19:44

No, this will not work, you're using GetBufferPointer which is a naked pointer to memory owned by FlatBufferBuilder, which will be deallocated upon leaving the function.

Like the docs you quote say, you must use ReleaseBufferPointer instead. Or make a copy, though that is obviously less efficient.

Better yet to structure your code such that the caller owns FlatBufferBuilder and its passed as an argument.

Please don't. Django templates are deliberately restricted, not to do this since business logic belongs in the view, not the template.

In the view, you can zip bar and data, so then the view looks like:

Can a function take both IntoIterator and IntoIterator<&T>?

Asked 2021-Jun-15 at 12:28

I want a function that takes two arguments, both of which can be turned into an iterator of Foo. The snag is that I'd like to accept things which are both IntoIterator and also IntoIterator<&Foo>. Importantly Foo is Copy so I can cheaply create an owned copy from it's reference.

The solution I currently have is:
