kandi X-RAY | swarming Summary
Handling a swarm of pingers. Pingers are, using different ISP, different technology, in different places. Pingers wait for targets, and ping them, periodicaly. It’s the DDOS pattern for quietly testing connection quality, and answering the remote worker question : it’s just me, or this service is slow?. For now, only classical ping is used (the ICMP one), later, http ping will be handled.

QUESTION
I have a question about Locust. I wrote simple script just to check if Locust work. It should check if I can login to app which I'm testing with phone number and password. I start it with command: locust -f LM.py --host=https://api... <-address of api to login
...ANSWER
Answered 2020-Jul-07 at 00:49I think the error is coming from your using User
instead of HttpUser
in the UserBehavior
class. See the quickstart.
HttpUser
providesself.client
for each session: "Here we define a class for the users that we will be simulating. It inherits from HttpUser which gives each user a client attribute, which is an instance of HttpSession, that can be used to make HTTP requests to the target system that we want to load test."
Also, you're using Locust 1.1 and task_set
has been removed. From the 1.0 changelog:
"The task_set attribute on the User class (previously Locust class) has been removed. To declare a User class with a single TaskSet one would now use the the tasks attribute instead:"
Try this:
QUESTION
I was wondering is it possible to run locust distributed on the local machine? I mean to create slaves and master locally. I tried next:
Master:
...ANSWER
Answered 2020-May-28 at 10:38Yes, it is possible to run locust distributed on the local machine. Note that you don't need to provide master-host parameter as it defaults to 127.0.0.1.
First, open the terminal and start the master using this command:
locust -f load_test_script.py --master
Then start slaves, each in a new terminal window:
locust -f load_test_script.py --worker
For optimal performance, the number of slaves on the local machine should not excide the number of CPU cores. Check official documentation for more info about running locust in distributed mode.

First time using Locust. I have a Flask App that requires user to login to access most routes. I cant get Locust to successfully login to my Flask App.
Here is my Locust.py file:

Answered 2019-Sep-16 at 13:46This is probably not an issue with Locust. Have you tried logging in and getting the token using something like Postman or cURL?
QUESTION
In April 2019, I already make an question custom dictionary, furthermore, I already improved to like a class.
My problem now, My code is already reusable or not? because when adding new data using behavior i should repeat this one:

Answered 2019-Aug-10 at 15:09Based on the comments, here's one possible example you can start building on:
Indexing by the keys 0
, 1
, 2
, ... signalizes that list
will be better structure than dict
to store values.
Here I use collections.namedtuple
to create named tuple Fish
with properties weight
, visual
, step
, fitness
, behavior
, following
. The class behaves like a tuple, so you can put it in for-loop
etc. If you need more customization, I suggest making custom class.
In a loop, I create as many Fish
instances as needed - in this case data_length

QUESTION
Lets say I have 10000 tasks at hand. How can I process them in parallel, running precisely 8 processes at any time? The moment a task is finished, the next task should be fetched for execution immediately.
...ANSWER
Answered 2018-Nov-12 at 05:22I think if you split the "for" loop for join statement your problem might be solved. Right now you start a fork and want the result to come back and go do another fork process. And no fork is closed right now.
QUESTION
This question became really long; I welcome comments suggesting better forums for this question.
I am modelling the swarming behavior of birds. To help me organize my thoughts, I created three protocols representing the main domain concepts I saw: Boid
, Flock
(collection of boids), and Vector
.
As I thought more about it, I realized that I was creating new types to represent Boid
and Flock
when those could be very cleanly modeled using spec'd maps: A boid is a simple map of position and velocity (both vectors), and a flock is a collection of boid maps. Clean, concise, and simple, and eliminated my custom types in favor of all the power of maps and clojure.spec
.
ANSWER
Answered 2018-Nov-08 at 12:57While there are certainly many valid answers to to this question, I'd suggest that you reconsider your goals.
By supporting both coordinate representations in the spec you are stating that they are both supported at the same time. This will inevitably lead to complexity overhead like runtime polymorphism. E. g. your Vector protocol needs to be implemented for Cartesian/Cartesian, Cartesian/Polar, Polar/Cartesian, Polar/Polar. At this point the implementations are coupled and you don't get the intended benefit of "seamlessly" alternating between representations.
I'd settle for one representation and if necessary use an external conversion layer.
QUESTION
I am working on a script where I need to calculate the coordinates for a beeswarm plot without immediately plotting. When I use beeswarm, I get x-coordinates that aren't swarmed, and more or less the same value:
But if I generate the same plot again it swarms correctly:
And if I use dev.off() I again get no swarming:
The code I used:
...ANSWER
Answered 2018-Jul-27 at 13:18You're right; beeswarm uses the current plot parameters to calculate the amount of space to leave between points. It seems that setting "do.plot=FALSE" does not do what one would expect, and I'm not sure why I included this parameter.
If you want to control the parameters manually, you could use the functions swarmx
or swarmy
instead. These functions must be applied to each group separately, e.g.
QUESTION
I'm trying to use hyperdb in browser with swarming via webrtc and signalhub. The code is pretty strait forward, but there is some issue with hyperdb replicate where the connecting is killed because of a sameKey check in hypercore. So, I'm thinking ... I'm not properly juggling my discovery keys and id keys so the peers know they should be sync'd. Here is some sample code, it is a bit of a mess but the relevant bits are the hyperdb initialization and the webrtc/signalhub stuff (I think) ... the key at the top is the discovery key of the other peer:
...ANSWER
Answered 2018-Jul-13 at 18:09I put up a working example here: https://github.com/joehand/hyperdb-web-example/blob/master/index.js
I think you are getting that error because you are not initializing the db with the key:
QUESTION
I found myself writing some tricky algorithmic code, and I tried to comment it as well as I could since I really do not know who is going to maintain this part of the code.
Following this idea, I've wrote quite a lot of block and inline comments, also trying not to over-comment it. But still, when I go back to the code I wrote a week ago, I find it difficult to read because of the swarming presence of the comments, especially the inline ones.
I though that indenting them (to ~120char) could easy the readability, but would obviously make the line way too long according to style standards.
Here's an example of the original code:

QUESTION
To start, if Overflow is not the right Stack site for this, please let me know! Also, if you need to see any other files, please feel free to ask.
I started a sample Visual Studio C#/ASP.NET MVC app to try and put in Docker as a Proof of Concept to see how to configure the two parts to work together. It works locally, but when deployed via Docker it throws an error.
...ANSWER
Answered 2017-Jun-19 at 15:14I had the same issue when trying to get an existing MVC app working in docker. I went all around the houses trying to resolve the issue and have spent many hours on it over the weekend! I tried setting permissions on various temp folders to various accounts and I tried setting the app pool to run with a local profile.
I finally got it to work by adding the app pool account to the local admins group. This isn't a final solution, but it's got it working and pointed me in the right direction for which account I need to assign permissions for.
Here is my Dockerfile;

Install swarming
You can use swarming like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
