What are important test scenarios specific to Universal Windows Platform (UWP) application?

We have developed a Windows application using Winforms. Now we are trying to convert it to Universal Windows Platform (UWP) using desktop to appx bridge.

I have to test this app and I’m new to UWP. I know I have to test all the app functions and make sure they work the same way as the original application, but I need to know what to look for that is specific to UWP.

Are there any test scenarios that only happen with UWP, and if there are, how do I test for them?

How important is it that I know all of the words for the technical terms when mentoring in my second…

Every year for the past few years, I’ve been mentoring at Scratch Day, helping the kids with their projects during the course of the workshops. The problem? This takes place in my second language, which I don’t use Scratch in. Since I don’t regularly find myself using Scratch in that language, I don’t really remember the words from year to year, and I’ll find myself often going “the one under that one”, or “the pink section”, or of course “thingy”.

Does this have a negative effect on the students if I’m not using the terms that they’ll be using, because I don’t know how to translate them exactly? Especially since for some of these kids, it’s the first time they’re using the platform.

The site itself and everything they’re doing has the correct terms; it’s just me stumbling giving them the wrong names.

Is this actively harmful, or just something that it’d be nice for me to work on, but not imperative?

Explaining why some parts of computer sciences are important

I am a computer engineer, and I’m teaching computer sciences 1 hour per week to a student who failed her second year university degree. She needed some help to have a better understanding of programming, and increase her grade in this field. Computer science is not the main subject of her degree which is based on maths and physics.

I asked her if she wanted to emphasis on difficult subject for her, or if I should start from scratch and explain programming as if it was totally new for her. She chose the second solution, so I started to explain her the base of programming, binary, variables, functions, conditional statements, loops. And now I emphasis on the most common data structure ever, the arrays.

I teach her how to use an array, manipulate its element, etc…
As she had to use programming to solve problems of Graph Theory, Physics measurments, Math algorithm which use a lot of matrices and arrays, I spend like 5-6 hours to make her be more familiar with it.

I simplified it to make her use 1 dimensional array with simple algorithm, and she just told me that she can’t understand how arrays will be of any use for her, for her everyday life. She aimed to get job in the field of statistics.

I explained to her, that she uses array everyday without thinking about it, for example when you log in a website, there’s somewhere an array ( or an object) which store you username, password, email compares it to what is stored in a database etc… But she didn’t feel very enthusiastic.

So I can understand that not everybody enjoy programming, and as I am not a statistician I can’t really tell her about how useful this can be for a statistician.

What can I do to actually make her change her mind about programming or show her the use of it for a statistician ?

How to get the most important variables in random forests in R?

I am building a random forest in R and was wondering how to extract the most important variables. I am using a random forest to classify if a click is fraud or not, and the goal is to identify characteristics that increase the probability of a click being fraud. Would the importance() and varImpPlot() R functions be helpful in identifying these variables or are there any other ways? The idea is to describe to a nontechnical client what the most important variables are. Are there any plots I could use to show the importance of these variables?

Why is it important to support a newborn’s neck?

Newborns have such floppy necks that they need support while being held. The question I have about this is, what are we trying to protect in supporting the head/neck ? My wife and I have a few possible ideas about this but aren’t sure which (if any) are accurate.

  • You want to support the neck/head to prevent the head from moving in an uncontrolled way, which could damage the brain.
  • Neck support could prevent the neck from being injured somehow. For example, if the neck is tilted to one side and a sudden muscle spasm pulls the head in the other direction, the baby could pull a muscle or something like that.
  • Head/neck support might just be a way of stabilizing baby to make him easier to hold, and less prone to “jumping” out of one’s arms.

Or perhaps there is another reason entirely ?
