QUESTION
Problem: I am plotting the colorbar using Matplotlib, but these ticks are set at 0.0, 0.1.. to 0.5.
I wanted to get more intervals in between, but that leads to me having this following problem : Irregularly spaced tick labels.
In this picture, I have marked in red the offset in the ticks.
Code:
...ANSWER
Answered 2017-Nov-21 at 16:04I could imagine you want to fix the boundaries of colors shown on the plot and in the colorbar to the values of numpy.linspace(0,.5,11)

QUESTION
I am trying to cancel multiple asynchronous web requests (GET) issued via a shared HttpClient
using CancellationTokens
, in a command-line application, full framework, .net 4.7.1, C# 7.3, VS 2017.
My example runs a couple of parallel tasks, each task is constantly downloading some data over Http, using an async GetAsync()
and ReadAsStringAsync()
but I get the same result using for example ReadAsByteArrayAsync()
.
Termination is done by hooking into Console.CancelKeyPress
and cancelling my CancellationTokenSource
.
Though this seems straight-forward for some reason I cannot get my head around it and come up with a solution that produces a reliable result. Sometimes everything shuts down as expected, i.e. all tasks complete (cancelled) but more often that not shutdown simply seemingly hangs. Running without debugger (with/without DEBUG) terminates the application but not in the way I expected. Fewer tasks means a more likely clean shutdown.
Pausing all threads in debug when in a "hang"-state seems to indicate some threads are stuck in GetAsync()
but it is a bit hard for to see exactly what goes on.
In reality it does not matter that much how the application exits but I would like to understand this and be able to produce a clean and controlled shutdown consistently, which to me seems possible using this construct, but I have most likely missed some details.
...ANSWER
Answered 2018-May-29 at 20:58Well, rubber ducking myself via StackOverflow worked yet again.
Ctrl+C
terminates the application if not canceled via args.Cancel = true
, so it has absolulutely zero to do with HttpClient
or CancellationToken
.
The fix is simply:

...ANSWER
Answered 2017-Nov-08 at 11:31When you run eval, unqualified symbols in the form are resolved in the current namespace at runtime (not that of the namespace where the function is defined).
To solve this, you can create a version of eval with the namespace bound to the one you need:

QUESTION
so this is my very first post and i am really sorry if my grammar is bad (english is not my mother language). I recently started programming in java and i am interested in learning. So i started a few small projects to help me understand more of the basic stuff and to improve my coding.
Recently i read about keyListeners, keyBindings and all that stuff. So i thought i code a very basic program (nearly no gui) which should work like a simple piano:
...ANSWER
Answered 2017-Feb-11 at 03:20The answer to your question revolves around what you ultimately want to achieve, if you simply want to stop more than one sound playing, then you need some kind of condition you can monitor, if you want to stop a "particular" sound from playing, then you need to maintain some kind of List
of flags which you can check.
So, based on your code, lets assume you're making a piano, so you want sounds to overlap, in this case, we need some way to determine if a particular sound is been played or not.
There are a number of ways to achieve this, but lets settle on a Set
, which allows you to maintain unique a List
of items (no duplicates).
Each time playSound
is called, we check this list and determine if the sounds is already been played or not, if it isn't, we add the sound to the list and play it, when the sound stops, we remove it from the list
I've changed your code a bit and I'll explain it more it detail later, but essentially, this is the "core" of the idea...
