count number of combinations by group

Asked 2022-Feb-18 at 12:58

I am struggling to count the number of unique combinations in my data. I would like to first group them by the id and then count, how many times combination of each values occurs. here, it does not matter if the elements are combined in 'd-f or f-d, they still belongs in teh same category, as they have same element:

ANSWER

Create a "combination" column in summarise, we can count this column afterwards.

An easy way to count the category is to order them at the beginning, then in this case they will all be in the same order.

There are Admins, and your Account exists, but none of the Admins are linked to that specific Account. The widget shows all Admins.

You thus can link Admins to an account by selecting these in the widget. In that case account.admins.all() will return the Admin objects selected for that account.

C++ sockets: accept() hangs when client calls connect(), but accept() responds to HTTP GET request

Asked 2021-Dec-14 at 05:06

I'm trying to write a demo server/client program in C++. I first ran my server program on my Macbook, with ngrok on and forwarding a public address on the Internet to a local address on my machine. I'm seeing something that I don't understand when I try to run my client program to connect to the server:

If the client tries to connect to localhost at the local port defined in the server program, the server accepts as expected and the client successfully connects,
If the client tries to connect to the ngrok server address at port 80 (default for ngrok), then the client connects, but the server is still blocked at the accept call. (This I don't understand!)
If I send an HTTP GET request to the ngrok server address, the server successfully accepts the connection.

Why do I see these? In the ideal case, I want my server to accept connections from my client program, not just respond to the HTTP GET request.

Here's my code if that helps: For the client,

Answered 2021-Dec-14 at 05:06

Contrary to the typical port forwarding done in the local router, ngrok is not a port forwarder at the transport level (TCP) but it is a request forwarder at the HTTP level.

Thus if the client does a TCP connect to the external ngrok server nothing will be forwarded yet. Only after the client has send the HTTP request the destination will be determined and then this request will be send to the ngrok connector on the internal machine, which then will initiate the connection to the internal server and forward the request.

How Can I Truncate HTML Table Cells using DataTable?

Asked 2021-Dec-07 at 10:08

I have an HTML table where some of the cells have very long text, I'm therefore trying to truncate them to a limited number of characters and add an ellipsis if they exceed it. To make the table more interactive I'm using datatables, so I tried to follow this datatables specific solution which uses their rendering features however it doesn't truncate values in my table. The example table where this isn't working can be found in this JS Fiddle.

OpenFOAM simple blockMesh floating point exception

Asked 2021-Nov-04 at 18:45

I am learning OpenFOAM step by step, and am currently trying to create a very simple mesh with the blockMesh tool, but keep getting a floating point exception. My blockMeshDict is written in almost exact correspondence to the meshing tutorial in the section 4.3.1 of the OF user manual:

...

ANSWER

Answered 2021-Nov-02 at 18:11

The problem with your blockMeshDict file is that you are not following these rules:

The local coordinate system is defined by the order in which the vertices are presented in the block definition according to:

the axis origin is the first entry in the block definition, vertex 0
the x direction is described by moving from vertex 0 to vertex 1;
the y direction is described by moving from vertex 1 to vertex 2;
vertices 0, 1, 2, 3 define the plane z = 0.
vertex 4 is found by moving from vertex 0 in the z direction.
vertices 5,6 and 7 are similarly found by moving in the z direction from vertices 1,2 and 3 respectively.
You must follow the right-hand rule when you specify the faces.

Here is a version of blockMesh that works correctly:

Parametrizing Ansys Fluent with python in linux

Asked 2021-Aug-25 at 11:57

I'm trying to do a parametric study in Ansys fluent through python. The idea is to calculate some parameters before feeding them to fluent as boundary conditions and initial conditions.

I have searched wide and far but could not come into any pertinent information... maybe i'm not looking with the good keywords.

Or is there an equivalent of ANSYS Parametric Design Language (APDL) for fluent ? I can only find information for mechanical.

Do anyone could guide me in the good direction or somewhere to go look for more information.

P.S. I could not find any information in CFD-online, ansys site or here in stack overflow.

Directly with scripting, I did not used this method hence this is what I understood without trying or testing it. You can run the workbench in batch mode with the following bash command :

weird output of spliting char array in C

Asked 2021-Jun-25 at 16:26

I work on the server side Socket (use Telnet client) in Linux. Client is required to input a line in certain format: (1)command(GET/PUT/DEL), (2)key and (3)associated value (spaces to seperate in between). This key-value pair is later passed accordingly to the function(GET/PUT/DEL), which saves the data in the shared memory (keyValueStore).

I try to spilt the input into 3 parts, but there are wierd result in reading Token(2).

may I know the reason? any advices on how to change my code? (what i expected are key1, key2 )

Thanks!

The result of strtok() refers to the source buffer, so strcpy(&input[i++], token); invokes undefined behavior by performing copy between overlapped objects.

In this case you should simply remove the line because the results of copy doesn't looks used.

If you want to use the tokens in the future, you should store them in a different way. Storing the pointers to each tokens may work (until new data is read to input). It will be like this:
