blackbox | Magically save your database backups | Cron Utils library

I have a list of signals with bitwidth information and directionality of the signals. I want to create these IOs on the fly and make use of the CustomBundle that extends Record. I was able to do this in a normal class that doesn't extend BlackBox. However when I use CustomBundle inside the class that extends blackboxes I run into errors. Can CustomBundles be used inside a class that extends blackbox? If not are there any workarounds other than scripting so that I can automate the construction of signals inside the blackbox class.

I am trying to create a page that contains a list of cards. I designed the Header of the page but as a beginner, but I created it in my own way.

Problem is that when I am trying to display the card in the new Grid container its will not showing the desired result. Here the Image with the head I created

Here the I the problem picture when I try to put Grid container

I am a starter with Scala 2 Macros (before I switch to Dotty) who after trying out the shapeless type class derivation wanted to go one step beyond and write a macro that can generate a type class instances for any scala.Product without it.

(for the sake of example let's ignore nested recursive types, so my goal is flat case classes.)

My type class is an abstract class Coder[T] (e.g. trait with encode() / decode()).

So the generated code for:

I'm wanting to create a script which can run k apply -Rf ./service-token-auth for each of the logical groups here. Mainly all of the graphql-* and data-service-* folders.

Is this something that would be quite easy to implement?

I was trying to use Logistic regression in OCaml. I need to use it as a blackbox for another problem I'm solving. I found the following site:

http://math.umons.ac.be/anum/en/software/OCaml/Logistic_Regression/

I pasted the following code (with a few modifications - I defined my own iris_features and iris_label) from this site into a file named logistic_regression.ml:

I'm looking(did some tests without success) to return a tuple StructType from a case statement without using UDFs, is there any way to do it?

Use case is: we have 2 columns that depend on the same conditions in a CASE expression so we see 2 options:

• writing the same conditions twice but returning different column (undesired)
• writing the conditions once but returning 2 values on every WHEN, this could be via a tuple that we then split.

I know it can be done using a UDF but we avoid UDFs due to being treated as blackboxes by spark and hence they are not optimizable, so the question is: is there any way to make a CASE statement return multiple values without using UDFS?

Something similar to:

I'm trying to write a macro which returns a value of a literal type passed as a type parameter and fails to compile if the parameter is not a literal type. Here are some examples:

Consider the following traits:

I am undertaking a new project encompassing large time-series datasets from which dependent calculations are fed into a shiny application. As such, efficiency is of interest to me. The operations are typically restricted to elementary period conversions and subsequent summary statistics for risk metrics.

I am investigating which library/approach to build the calculation scripts with. At present, I am OK with xts and data.table. Although I can resort to libraries as quantmod and TTR, I am hesitant to deploy blackbox functions in production and would prefer to maintain full traceability.

Thus far, I have carried out the following benchmarking exercise in which a data.frame of daily prices is converted into monthly returns. The packages used thus far are xts, data.table and quantmod (as reference). The code is pasted below but can also be found on GitHub.
