I have written a JavaFx Application(JDK 8), which parses a private format XML (XML contains all of the Shape attributes such as coordinate, size, fill, stroke and so on) to construct a scene graph with about 4000-5000 Nodes layout according to their coordinate in the SubScene.
Every time I open a new private XML, the new SubScene needs 2-3 second lagged to show in my screen.
I tried "-Djavafx.pulseLogger=true" in VM argument,and show the logger below, but I do not know how to optimize the show time. I tried to force the node parent Group with no layout pass, but the time till very big. I also read the articles abort how to optimise the performance abort Javafx, but I still cannot fixed the lag performance correct.

I have a script that allow me to connect to Azure ML Workspace. But it only works in local (interactive authentification) or on Cluster Instances while doing experiences.
But I can not manage to make it work in Compute Instances.

I do not want to use SDK2, it will break all my existing code.
I don't understand why the identidy is not automatically managed when starting the Compute Instances like Cluster Instances.
Does any one has a solution for this?
Use the below code blocks to connect to the existing workspace using the python SDK using the compute instances.
Create a compute instance
from azureml.core import Workspace
ws = Workspace.from_config()
ws.get_details()
Output:
Connecting to workspace using Config file:
import os
from azureml.core import Workspace
ws = Workspace.from_config()
I'm using QTabWidget(s) inside QTabWidget tabs and when I try to get a "child" QTabWidget which is stored in the layout of a tab of the "parent" QTabWidget, I have an segment-fault error.
PS : I'm using Qt Creator v4.8.1, Qtv5.6.3 and Windows 7 64-bits OS (VM under VBox v6.0.4)
Initially, the following line throws the error
dbTablesTabWidget = static_cast<QTabWidget*>(ui->tabWidget->currentWidget()->layout()->takeAt(i)->widget());
I have tried without the "static_cast" with the following line but the error is always here
QWidget *widget = ui->tabWidget->currentWidget()->layout()->takeAt(i)->widget();
My last try (without return the QWidget pointer) with always the same "segment-fault" error.
ui->tabWidget->currentWidget()->layout()->takeAt(i)->widget();
That I don't understand is that the following line (first line in the first for loop)
QString itemClass = ui->tabWidget->currentWidget()->layout()->takeAt(i)->widget()->metaObject()->className();
works fine althought it includes the same "base code".
The segment-fault error appears in the "qobjectdefs_impl.h" file :

ui->tabWidget->currentWidget()->layout()->takeAt(i)->widget();
tableIndex = dbTablesTabWidget->currentIndex();
}
}
I'm a newbie with Qt and I don't see where the segment-fault error could come from.
The compilation process is OK, please see below (french language version)

Your page in tabwidget can have any widget along with a child tab widget.
To keep it simple, probably you can try the below way:
//GET YOUR CURRENT PAGE IN FIRST TAB WIDGET
QWidget *widget = ui->tabWidget->currentWidget();
//FROM THE CURRENT PAGE FIND THE CHILD TAB WIDGETS
QList<QTabWidget*> tabWidgets = widget->findChildren<QTabWidget*>();
//USE THE FOUND WIDGET FOR YOUR PURPOSE. DO SOME SAFETY CHECKS FOR LIST.
QTabWidget* requiredTabWidget = tabWidgets[0];
I have finally found the error :
I should use layout()->itemAt(i) instead layout()->takeAt(i).
It explains why the error occurs at the second time.
takeAt remove the item from the list, so during the next call, the item doesn't exist in the list.
PS : for QList object, this is at instead itemAt to get the element from the list of element.
I'musing Graphviz to render some hierarchical structure. So far the use of subgraphs has been sub-optimal for achieving what I'm looking for.
This is what I would like to get
(colors represent different tiers in the hierarchy so they need to follow this order). For making this image I used invisible links, but that's really not an option in a real world scenario.
However, at the moment this is what I'm getting
using this .dot file
graph {
// Global config
rankdir=BT
node [style="filled" fontcolor="white" shape="box"]
// Rank (hierarchies)
{ rank=same; 258 }
{ rank=same; 259 }
{ rank=same; 260 }
{ rank=same; 261 262 }
// Nodes
// Tasks
258 [label="John Cleese" fillcolor="#E8B04D"]
// Project Goals
259 [label="Michael Palin" fillcolor="#C0C56B"]
// Identities
260 [label="Eric Idle" fillcolor="#FF8D61"]
// Virtues
261 [label="Graham Chapman" fillcolor="crimson"]
262 [label="Terry Jones" fillcolor="crimson"]
// Edges
259 -- 260 [style="bold" color="#3790af"]
}
Is it posible for Graphviz to honor rank before edges? If so, how would I proceed?
Your problem is easily solved by the addition of a few invisible edges that make the various ranks (that you set up correctly) work as you want. Note the simple addition of three invisible edges near the bottom:
graph {
// Global config
rankdir=BT
node [style="filled" fontcolor="white" shape="box"]
// Rank (hierarchies)
{ rank=same; 258 }
{ rank=same; 259 }
{ rank=same; 260 }
{ rank=same; 261 bl 262 }
// Nodes
// Tasks
258 [label="John Cleese" fillcolor="#E8B04D"]
// Project Goals
259 [label="Michael Palin" fillcolor="#C0C56B"]
// Identities
260 [label="Eric Idle" fillcolor="#FF8D61"]
// Virtues
261 [label="Graham Chapman" fillcolor="crimson"]
262 [label="Terry Jones" fillcolor="crimson"]
// Edges
259 -- 260 [style="bold" color="#3790af"]
258--259 [style=invis]
260--261 [style=invis]
260--262 [style=invis]
260--bl [style=invis]
bl [style=invis label="" height=0, width=0]
}
I also added an invisible balancing node in the center, bl to help center the graph better.
I've updated Xamarin Forms in my Xamarin project. Now this code doesn't work any more.
var view = (View)ItemTemplate.CreateContent();
if (view != null) {
var bindableObject = view as BindableObject;
if (bindableObject != null)
bindableObject.BindingContext = newItem;
_imageStack.Children.Add(view);
}
The problem is (View)ItemTemplate.CreateContent() goes in error:

My function save an image in memory from the camera in ImageSource format, byte[] and the length in byte of this image.
This indicates that the XAML you are loading contains a {x:Reference foo} markup extension and, at runtime, no element defined with a x:Name="foo" was found in the hierarchy.
Without seeing your XAML, it's impossible to figure if the issue is in your code, or if it's a bug in Xamarin.Forms.
I get random friendly 500 and 404 errors on my Gitlab installation. Everything works fine except that.
It is really annoying, sometimes the pages work, sometimes I need to refresh the page a couple of times for it to display.
Here's the errors I get in /etc/httpd/logs/error_log

I am new to the Ruby world.
Additional Notes:
OS: Centos 5
Gitlab v2.8.2
The issue almost never appears on admin pages or what not.. only on repository pages such as file tree, graphs or commits
