Working on a Jenkins pipeline, I observed what looks like infinite recursion causing a stack overflow when I use JsonOutput.toJson() on a net.sf.json.JSONObject that slurped a JSON string containing null.

The following minimal code demonstrates the problem:

Say you have a bunch of actions for creating/inserting records into a bunch of different database tables. You have some records which can be inserted without any dependency on the output of any other insert. You have some which need to wait for one other thing to finish. And you have others that need to wait for many things to finish, which might finish at different times in the flow.

How can you write an algorithm which would sort and chunk the actions in the dependency tree so the inserts / database actions can be optimally batched? By optimally batched, I mean if you can insert 10 records into the same table at once, then do that. Any time you can batch insert, you should, to minimize the number of database calls/inserts.

Here is a snippet from the example code I whipped together with a fake sequence of actions using a simple data structure to capture all the required information.

Given the following text:

I've been struggling with this problem for sometime, but now I'm coming back around to it. I'm attempting to use selenium to scrape data from a URL behind a company proxy using a pac file. I'm using Chromedriver, which my browser uses the pac file in it's configuration.

I've been trying to use desired_capabilities, but the documentation is horrible or I'm not grasping something. Originally, I was attempting to webscrape with beautifulsoup, which I had working except the data I need now is in javascript, which can't be read with bs4.

Below is my code:

I have trouble to grasp how to use colors in CGA/EGA/VGA video graphics modes. The video modes I'm particularly interested in are 0Dh (EGA 320x200) and 12h (VGA 640x480). Both of these modes have 4 planes, thus 16 colors.

My (probably incorrect) understanding is that I should activate a set of planes by writing a bitmask to port 03C4h, then when I write to video memory, the data only gets written to the activated planes. Mostly I used this document to get my information, though I also encountered several other tutorials and discussions: http://www.techhelpmanual.com/89-video_memory_layouts.html

Now I'm trying to write pixels in all possible colors in the first word in the video memory (top left part of screen). I load 1 for the initial bitmask to AH and 1 bit to BX. Then in a loop, I increment AH and shift (SHL) the bit in BX to hit a different pixel next time. I OR BX to A000h:0000h to add each pixels by leaving the already existing pixels untouched.

What I'm expected to see is a line of pixels in all possible 16 EGA colors on the top left of the screen. What I actually see is 7 white and 1 bright yellow dots with black pixels in between them. What am I doing wrong?

Also, every tutorial says that I must write 0005h to port 03CEh before I start to use planes. What is the purpose of that? When I comment those lines out, I can still use planes (I mean, in other programs). Previously I had success using planes when I was writing to different words in video memory (so I didn't need different color pixels in one block of 16 pixels that's represented by a single word in video memory); and when I used BIOS functions (e.g. INT 10h/AH=0Ch) to write pixels, but still I want to understand how to use planar graphics without BIOS, as I believe the BIOS functions are slow.

Here is my code (indentation is optimized for 8-width tabs, so it kind of looks off here):

Some NumPy functions (e.g. argmax or cumsum) can take an array as an optional out parameter and store the result in that array. Please excuse my less than perfect grasp of the terminology here (which is what prevents me from googling for an answer), but it seems that these functions somehow act on variables that are beyond their scope.

How would I transform this simple function so that it can take an out parameter as the functions mentioned?

I am trying to get the grasp of rvalue references and move semantics with a simple self-made example but I can't understand a specific part. I have created the following class:

I'm trying to learn MVVM to make my app's architecture more clean. But I'm having a hard time grasping how to create a "Domain" layer for my app.

Currently this is how the structure of my project is looking:

My View is the activity. My ViewModel has a public method that the activity can call. Once the method in the ViewModel is called, it calls a method in my Repository class which performs a network call, which then returns the data back to the ViewModel. I then update the LiveData in the ViewModel so the Activity's UI is updated.

This is where I'm confused on how to add a Domain layer to the structure. I've read a lot of Stackoverflow answers and blogs about the Domain layer and they mostly all tell you to remove all the business logic from the ViewModel and make a pure Java/Kotlin class.

So instead of

View --> ViewModel --> Repository

I would be communicating from the ViewModel to the Domain class and the Domain class would communicate with the Repository?

View --> ViewModel --> Domain --> Repository

I'm using RxJava to make the call from my ViewModel to the Repository class.

I thought I grasped the concept of hoisting, but the code below got me confused. How does it return 1? Will the second example() function be hoisted above the first one?
