kandi X-RAY | nodec Summary
Warning: this library is still under heavy active development and experimental. It is not yet ready for general use. Current development is mostly for Windows x64 using Visual Studio 2017, but the library has also been tested on Ubuntu Linux (AMDx64) and a Raspberry Pi (ARMv7). NodeC is a lean and mean version of Node.js which aims to provide similar functionality as Node.js but using C directly. The main goal is improved efficiency and resource usage (in particular more predictable resource usage) but robust and asynchronous. Previously, this would be very cumbersome as async/await style programming is very difficult in C. NodeC uses the libhandler library to provide algebraic effect handlers directly in C, making it much easier to write such code. Preliminary NodeC API documentation is available. For a primer on algebraic effects, see the relevant section in the koka book.

QUESTION
I am trying to find the highest scoring fulltext query from two nodes:
...ANSWER
Answered 2021-Jun-07 at 20:28We can use the results of the first search to boost the score of the second, based on which movie node the actor node acted in.
You haven't told us what you want to do with the scores mathematically, so for this example I'll just add them.
QUESTION
I want to extract the Giant component from a Gephi graph. I'm currently working on a graph too large for using Gephi's own giant component function, Gephi just freezes. So my problem now is that I want to extract only the nodes which are part in the giant component from my edges.csv file to be able to remove all nodes not included in the giant component, making the file smaller and manageable for Gephi.
I want to solve this using Python and I know there is a lib for python called networkx, can my problem be solved through networkx easy? My edges.csv is on the format:
...ANSWER
Answered 2020-Oct-29 at 17:27You can read your graph in from a pandas DataFrame and use the connected_component_subgraphs
function (see docs) to split the graph into connected components then and get the largest component from that.
Example reading your graph and making a networkx graph
QUESTION
I have a firebase function that does lot of checks in the firebase realtime database and then returns a response.
Does the node runtime in firebase garantee that the async functions will be executed in the order they are call? or there is some sort of non fifo scheduler that executes then?
the logic of the real function is a bit complex (over 200 lines) so to avoid the extra complexity i will just use a pseudo function as example:
...ANSWER
Answered 2020-Aug-20 at 15:53try async and await for this case, in your code, you will send the response to the user before finishing all the validation, there is no guarantee the callback function for each promise will execute in the same order.
QUESTION
I'm new to bash scripting and I need to make a script that will go through files of logs about jobs that ran and I need to extract certain values such as the memory used and then the memory requested to calculate the memory used.
To begin this I'm simply trying to get a grep command that will grep a value between two patterns in a file, which will be my starting point for this script.
The file looks something like this:
20200429:04/29/2020 04:25:32;S;1234567.vpbs3;user=xx group=xxxxxx=_xxx_xxx_xxxx jobname=xx_xxxxxx queue=xxx ctime=1588148732 qtime=1588148732 etime=1588148732 start=1588148732 exec_host=xxx2/1*8 exec_vnode=(xx2:mem=402653184kb:ncpus=8) Resource_List.mem=393216mb Resource_List.ncpus=8 Resource_List.nodect=1 Resource_List.place=free Resource_List.preempt_targets=NONE Resource_List.Qlist=xxxq Resource_List.select=1:mem=393216mb:ncpus=8 Resource_List.walltime=24:00:00 resource_assigned.mem=402653184kb resource_assigned.ncpus=8
The values in bold are what I need to extract. Its multiple jobs and dates, so the file goes on with multiple paragraphs like this of data with different dates and numbers.
From going through similar questions online, I've come up with:

QUESTION
I've been working on a project for the past few days that involves three linked lists.
Here is an example of the header with the nodes and the lists themselves:
...ANSWER
Answered 2020-May-06 at 08:52This won't help you with your concrete problem at hand but I think you should use standard containers like std::vector<>
. Implementing your own linked list is a nice finger exercise but seldom really necessary. That said, you should use std::vector
instead of lista_produto

QUESTION
I'm writing code to implement extension by definitions in mathematical logic.
It takes in a description of languages and their extensions, and it outputs a new haskell file which will parse a high-level language into a lower-level one. Of course, if I can turn language C into language B, and language B into language A, then by composing I can turn C to A.... and yet...
Here is a minimal example of the problem I'm facing:
...ANSWER
Answered 2020-Apr-27 at 02:12You're doing the right things. And you're right to be cautious about Overlapping instances
warnings. In this case it is coherent. And you're not afraid of language extensions, so you want:

I want to represent relationships between nodes in python using pandas.DataFrame And each relationship has weight so I used dataframe like this.
...ANSWER
Answered 2020-Apr-08 at 05:43This seems like an acceptable way to represent a graph, and is in fact compatible with, say, nextworkx
. For example, you can recover a nextworkx

QUESTION
a couple of weeks ago i just got a test for a job interview, the thing is that i've resolved almost everything except one point, that at this point, i guess it's impossible to resolve. but for sure i'm wrong.
This problem deals with related data. Our server API, IRepository, will only return a node with its immediate children (for example imagine that FakeRepository is loading from a Database. You must not change the code in FakeRepository for this test).
Imagine that the NodeManager is client side code.
We want to make sure that there is only ever one instance of a specific object on the client, so that our client has a consistent view of data in our application. The test “LoadingNodeB_ShouldAlwaysReturnTheSameInstance()” demonstrates this problem. Modify the code in the NodeManager so that this test passes.
so, we have this IRepo
...ANSWER
Answered 2020-Mar-01 at 19:55Assuming that a node is uniquely identified by its name, one way of making sure you return the same instance is to keep a local cache in the client and maintain the Node.ImmediateChildren
collection every time a call is made to the repository:
QUESTION
I feel really confused about how nodes are referenced to each other in linkedlist. Supposed we have code like this:
NodeA: 1->2->3;
NodeB: 6->7->8;
ListNode NodeC = NodeA;
IF WE DO:
NodeC.next = NodeB;// NodeC becomes 1->6->7->8, NodeA also changed to 1->6->7->8, why?
OR WE DO:
NodeC = NodeB;//this will only change NodeC, but NodeA stay the origin, why?
When we set two nodes are ponitning to the same, and if we change one node to point different next, the another one also get changed. However, if we only say NodeC = NodeB, it seems like there is nothing changed on NodeA. I have been struggling this for few days, could anyone explain how this work? really appreciate !
...ANSWER
Answered 2020-Feb-03 at 14:34When you say NodeA: 1->2->3;
, there are 3 nodes being referenced, and 1 variable:
QUESTION
Suppose I have the following network:
...ANSWER
Answered 2019-Aug-21 at 10:29Mark all your modules with a specific property in NED (i.e. something like the @NetworkNode property in INET) and then you can use the cTopology::extractByProperty()
call to extract a topology of those marked modules.
For example, topo.extractByProperty("node");
would extract all modules that contain the @node
property, like the following one:
