I am trying to calculate the district heating system. I get the info from shapefiles – for pipes I have a geometry of linestrings with start and end coordinates. I created a geopandas dataframe:

I have compressed data in zlib format that is inside a std::vector

I'm trying to figure out a way to write a function that takes that data and returns another vector with the inflated data. The function does not even need to check if it's valid zlib data etc. just something in these lines:

I am trying to write a simple program that passes a value from a process to another without having father-child properties using named pipes.Code i've writen:

I`m trying to make a puzzle game where the player is presented with a grid of pipes with one water source. The player has to rotate the pipes in order to connect them all to each other and, of course, to the water source.

The problem I`m stuck with is this:

Step 1:

Step 2:

Step 3:

As shown in the pictures, when I rotate a pipe that is connected to a group of other pipes, the connection to the water isn`t broken in the remaining group, it only works in a single adjacent pipe.

This is happening because of the way I`m doing the connections using a group of colliders in each exit of the pipes, as shown in the pictures below.

Colliders - Scene:

Colliders - Hierarchy:

If the collided object is connected to water (by a bool), it adds the collided object to a list. If the list is greater than 0, activates the blue sprite. If the list is empty, deactivates the blue sprite. As shown in the code sample below.

Triggers that check if the object is connected to water:

I've got a sample program as below, w.cpp on ubunt 18.04 with g++7.3.0

I am working on an inter-process communication between a .net (v4.5.2) and Javascript node.js (v8.9.0) application. I want to use Windows named pipes for this (and only named pipes). For the Javascript application, I am using the named-pipes package (v0.0.1) I am able to establish a connection between the two applications which tells me that I am not completely off base here. I would expect to see the data event being triggered in the JavaScript application whenever I am writing a string to the NamedPipeServerStream but no data is received. I can not receive any data. Here is the code for .net and the JavaScript application. Any ideas, why that the data event is not triggered?

This is a bit of a design question involving inner classes in Java (Java 8). All of the example code is below my text

As an example, let's say I have some machinery that involves pumping fuel from an oil geyser to some sort of burner, which I can control using an external API called OilAPI.

I have a Controller class which is doing the work and decides which burner needs to get oil from which geyser, but I don't want the logic of using the API's classes like Geyser and Burner to leak out into the Controller (also since the API does still undergo some changes over time).

Now, to encapsulate it, so I create a class called FuelFacility which contains all of the logic of the OilAPI.

The thing is, I've put the classes Pump and Engine as inner classes inside of FuelFacility.

First of all, this is for the syntax of being able to go Pump.activate() instead of FuelFacility.activatePump(...) or whatever.

Further is that in order to connect a Geyser and Burner in the Oil API, you need both the Geyser and Burner objects, but I don't want to expose them externally, so in order to have some sort of "Connect Pump and Engine" method, I have to allow either the Pump to access the Engine's Burner variable, the Engine to access the Pump's Geyser +variable, or the FuelFacility to access both these variables. In the example below, I have a Engine.connectToPump(pump) method, which is basically the way it works in my actual code.

My teammates thought that this is a bit strange; they said that the accessing the private variables across the classes breaks encapsulation, and especially that a programmer looking at the code from the "outside" (i.e., from the point of view of working in the Controller class) would assume that once you have obtained the Engine and Pump objects, they would no longer depend on e.g. which OilAPI object the original FuelFacility is using (although this should remain final, as I've done below) nor on each other.

Now, since then, I've managed to change their minds a bit - that basically this is just a way of doing things that they're not used to, but that it's not bad practice.

However, now I am busy altering some other code to work in a similar fashion to this, and I just want to make sure before I continue, is what I am doing good practice? Is there a better way of doing things? Advice is appreciated!

I am currently in the process of learning pipes. While playing around with bidirectional pipes I noticed that unfold composition looks pretty similar:

I have some Haskell code that uses Pipes:
