My linux (i5 Processor, RAM: 16GB) machine is able to handle 100k users easily however same does not happen with Windows 8 (i7 Processor 2600 @ CPU 3.40GHz, RAM: 32GB) and thread creation stops after specific amount of thread is created somewhere around 20k in JMeter.
Is there any reason as why Windows in not able to handle huge number of users?
I have a table where is some case we are missing the location record for location = 'WHS1'. You will notice the bottom 2 "TCODE's" do not have a location = WHS1 record
I was thinking of doing a select distinct on TCODE InvYear and to get unique records then checking to see if the Location 'WHS1' NOT Exist.
I'm very green at this that you for any help

I'm working on an Android app, which streams live audio from mic to the vlc using native android RTP lib (using AudioStream and AudioGroup) with in the same room on the speaker(it is conference app, so MIC and Speaker both will be in same room) the problem is, it is creating a lot of ECHO, i know the android have native Android API AcousticEchoCanceler and also NoiseSuppressor API but these APIs work with AudioRecord or MediaRecorder... I need some hep, how can i remove Echo using these native APIs with RTP lib OR Anyone can suggest me any 3rd party lib which streams live audio with built-in Echo canceler..
Here is the link you can see, they are streaming live audio in the same room, without any echo, we are working on the same concept of live streaming...
Thanks in advance...!
Hi Please help a Powershell newbie with a seemingly simple task which is doing my head in.
I have a folder containing a large list of hofixes. Each hotfix filename contains the KB number such as KB2993958 similar to Windows8.1-KB2957189-x64.msu
I'm trying to troubleshoot an issue caused by the installation of a particular hotfix. I have narrowed the selection down to about 50 possible hotfixes, far less than how many are contained in the master folder. I want to install 10 hotfixes at a time to try and isolate the issue.
I have the list of 50 hotfixes I need to install either in a get-hotfix object or probably converted to a string in a variable.
So I want to compare the Kb numbers listed in my object / variable against the file names in the master folder and if the file name contains any of the KB number stored in my variable then move this file into a folder, ready for installation. Seems simple. Can't work it out.
Please help. Feeling a bit dumb right now :( Many Thanks!!
I've developed a little mode for emacs which applies enriched format (colors, different fonts, etc) to some pieces of text using regular expressions (as markdown does).
In some of these regular expressions, there's french and spanish characters (like ``), and unicode characters (like ☛). Usually I use emacs in no windows mode (-nw), but to edit files which uses my mode, I open emacs in windowed mode, and I've realized that in windowed mode I can't write non-ascii characters, like ` or ☛. So, I can't use these special patterns (files are utf8).
If I execute describe-input-method in emacs, it says that no input method is specified, both in windowed and nw mode. However, it's not crazy to say the input method is different in windows and nw mode, since in boths modes the characters I'm able to write are different; or have I misunderstood what the meaning of input mode in emacs is?
I started reading more about EF. I believed that entities are tracked as long as the context is in scope. But when I try the code below I get different results. I'm sure I misunderstood what I read. Can you please explain.
Destination canyon;
DbEntityEntry<Destination> entry;
using (var context = new BreakAwayContext())
{
canyon = (from d in context.Destinations.Include(d => d.Lodgings)
where d.Name == "Grand Canyon"
select d).Single();
entry = context.Entry<Destination>(canyon);
}
Console.WriteLine(entry.State); //Unchanged
canyon.TravelWarnings = "Carry enough water!";
Console.WriteLine(entry.State); //Modified
I have the following code that paints 4 points in a canvas3D window
public final class energon extends JPanel {
int s = 0, count = 0;
public energon() {
setLayout(new BorderLayout());
GraphicsConfiguration gc=SimpleUniverse.getPreferredConfiguration();
Canvas3D canvas3D = new Canvas3D(gc);//See the added gc? this is a preferred config
add("Center", canvas3D);
BranchGroup scene = createSceneGraph();
scene.compile();
// SimpleUniverse is a Convenience Utility class
SimpleUniverse simpleU = new SimpleUniverse(canvas3D);
// This moves the ViewPlatform back a bit so the
// objects in the scene can be viewed.
simpleU.getViewingPlatform().setNominalViewingTransform();
simpleU.addBranchGraph(scene);
}
public BranchGroup createSceneGraph() {
BranchGroup lineGroup = new BranchGroup();
Appearance app = new Appearance();
ColoringAttributes ca = new ColoringAttributes(new Color3f(204.0f, 204.0f, 204.0f), ColoringAttributes.SHADE_FLAT);
app.setColoringAttributes(ca);
Point3f[] plaPts = new Point3f[4];
for (int i = 0; i < 2; i++) {
for (int j = 0; j <2; j++) {
plaPts[count] = new Point3f(i/10.0f,j/10.0f,0);
//Look up line, i and j are divided by 10.0f to be able to
//see the points inside the view screen
count++;
}
}
PointArray pla = new PointArray(4, GeometryArray.COORDINATES);
pla.setCoordinates(0, plaPts);
Shape3D plShape = new Shape3D(pla, app);
TransformGroup objRotate = new TransformGroup();
objRotate.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
objRotate.addChild(plShape);
lineGroup.addChild(objRotate);
return lineGroup;
}
public static void main(String[] args) {
JFrame frame = new JFrame();
frame.add(new JScrollPane(new energon()));
frame.setSize(300, 300);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
Now i want to add a timertask that regularly updates the position of one of the points in the plaPts Point3f array. However, when i call plaPts[1].setX(2), nothing happens on the screen, they remain in the same position.
Do you have to have each point in a separate TransformGroup (consisting of a shape3D with a Point3f array of size 1) for this to be possible? I'm later going to use 100000 points, is it bad for performance if they all are in separate TransformGroups? Is there an easier way of doing this? Something like shape3D.repaint(), that automatically updates the position of the points based on the new values in plaPTS.
The scala Future class has several methods that are based on functional programming. When called from Java, it looks like using lambdas from Java 8 would be a natural fit.
However, when I try to actually use that, I run into several problems. The following code does not compile
someScalaFuture.map(val -> Math.sqrt(val)).
map(val -> val + 3);
because map takes an ExecutionContext as an implicit argument. In Scala, you can (usually) ignore that, but it needs to be passed in explicitly in Java.
someScalaFuture.map(val -> Math.sqrt(val),
ec).
map(val -> val + 3,
ec);
This fails with this error:
error: method map in interface Future<T> cannot be applied to given types;
[ERROR] val),ExecutionContextExecutor
reason: cannot infer type-variable(s) S
(argument mismatch; Function1 is not a functional interface
multiple non-overriding abstract methods found in interface Function1)
where S,T are type-variables:
S extends Object declared in method <S>map(Function1<T,S>,ExecutionContext)
T extends Object declared in interface Future
If I actually create an anonymous class extending Function1 and implement apply as such:
someScalaFuture.map(new Function1<Double, Double>() {
public double apply(double val) { return Math.sqrt(val); }
},
ec).
map(val -> val + 3,
ec);
I get an error that
error: <anonymous com.example.MyTestClass$1> is not abstract and does not override abstract method apply$mcVJ$sp(long) in Function1
I have not tried implementing that method (and am not sure if you can even implement a method with dollar signs in the middle of the name), but this looks like I am starting to wonder into the details of Scala implementations.
Am I going down a feasible path? Is there a reasonable way to use lambdas in this way? If there is a library that makes this work, that is an acceptable solution. Ideally, something like
import static org.thirdparty.MakeLambdasWork.wrap;
...
wrap(someScalaFuture).map(val -> Math.sqrt(val)).
map(val -> val + 3);
I have a simple situation which probably require a complex way to be solved but I'm unsure of it.
Basically I have this object which encapsulated a member function:
template<class T, typename R, typename... ARGS>
class MemberFunction
{
private:
using function_type = R (T::*)(ARGS...);
function_type function;
public:
MemberFunction(function_type function) : function(function) { }
void call(T* object, ARGS&&... args)
{
(object->*function)(args...);
}
};
This can be used easily
MemberFunction<Foo, int, int, int> function(&Foo::add)
Foo foo;
int res = function.call(&foo, 10,20)
The problem is that I would like to call it by passing through a custom environment which uses a stack of values to operate this method, this translates to the following code:
int arg2 = stack.pop().as<int>();
int arg1 = stack.pop().as<int>();
Foo* object = stack.pop().as<Foo*>();
int ret = function.call(object, arg1, arg2);
stack.push(Value(int));
This is easy to do directly in code but I'd like to find a way to encapsulate this behavior directly into MemberFunction class by exposing a single void call(Stack& stack) method which does the work for me to obtain something like:
MemberFunction<Foo, int, int, int> function(&Foo::add);
Stack stack;
stack.push(Value(new Foo());
stack.push(10);
stack.push(20);
function.call(stack);
assert(stack.pop().as<int>() == Foo{}.add(10,20));
But since I'm new to variadic templates I don't know how could I do in efficiently and elegantly.
We are using Typescript with Intellij Webstorm IDE.
The situation is we use ES6 import syntax and tsc compiler 1.5.3 (set as custom compiler in Webstorm also with flag --module commonjs)
The problem is it is imposible to click through (navigate to) method from module (file)
// app.ts
import * as myModule from 'myModule';
myModule.myFunction();
// myModule.ts
export function myFunction() {
// implementation
}
When I click on .myFunction() in app.ts I expect to navigate to myModule.ts file but this doesn't happen?
I have this simple example of using a functor in C++:
#include <memory>
#include <ostream>
#include <iostream>
template <typename T>
struct Point {
T x, y;
Point(T x, T y) : x(x), y(y){};
Point(){};
Point<T> operator+(const Point<T>& other) {
this->x += other.x;
this->y += other.y;
return *this;
}
};
template <typename T>
struct AddSome {
AddSome(){};
AddSome(T* what) { add_what = (T)*what; };
AddSome(T what) : add_what(what){};
T operator()(T to_what) {
if (ptr) {
return to_what + add_what;
}
return to_what + add_what;
};
private:
std::shared_ptr<T> ptr;
T add_what;
};
int main(int argc, char* argv[]) {
Point<int>* pt = new Point<int>(5, 6);
AddSome<Point<int>> adder5(pt);
Point<int> test = adder5(*pt);
std::cout << test.x << " " << test.y << std::endl;
return 0;
}
In the version above it works very well but it doesn't work at all if I delete the default constructor of the Point class.
What does the compiler need this constructor for?
I would like to develop an android app acting like an indoor positioning system.But I am stuck ,I don't know where to begin.I would like to know what is the best technology to use. I also want to know if there's a way to build this app based on BLE technology with beacons detection. Any information provided will be very helpful and thank you in advance.
I have a numeric string column in oracle with or without leading zeros samples:
00000000056
5755
0123938784579343
00000000333
984454
The issue is that partial Search operations using like are very slow
select account_number from accounts where account_number like %57%
one solution is to restrict the search to exact match only and add an additional integer column that will represent the numeric value for exact matches.
At this point I am not sure we can add an additional column,
Do you guys have any other ideas?
Is it possible to tell Oracle to index the numeric string column as an integer value so we can do exact numeric match on it?
for example query on value :00000000333
will be:
select account_number from accounts where account_number = '333'
While ignoring the leading zeros.
I can use regex_like and ignore them, but i am afraid its going to be slow.
How do I have to configure my SQL Server Express connection string that the server attribute accepts the computername where the SQL Server is running aka the current machine:
<connectionStrings>
<add name="MyDbConn1"
connectionString="Server=.\SQLEXPRESS;Database=MyDb;Trusted_Connection=Yes;"/>
</connectionStrings>
I have seen somewhere a configuration like the above where the server attribute has the .\SQLEXPRESS value.
What does that dot notation mean?
I have this query
SELECT CONVERT(VARCHAR(20),(((currentytd - PreviousYTD) / PreviousYTD) * 100)) + '%' as ytdGrowth from ytd
It is returning: 11.224300%
I would like to return: 11.22%
I am very new SQL so trying to find the correct way to accomplish this.
I have a series of textareas that all follow the same format nested html format but I need to target one specifically. The problem I'm having is that the unique value I can use to identify the specific textarea is a parent's sibling's child.
Given this html
<fieldset>
<legend class="name">
<a href="#" style="" id="element_5014156_showhide" title="Toggle “Standout List”">▼</a>
</legend>
<ul id="element_5014156" class="elements">
<li class="element clearboth">
<h3 class="name">Para:</h3>
<div class="content">
<textarea name="container_prof|15192341" id="container_prof15192341"> TARGET TEXTAREA</textarea>
</div>
::after
</li>
<li class="element clearboth">
<h3 class="name">Para:</h3>
<div class="content">
<input type="text" class="textInput" name="container_prof|15192342" id="container_prof_15192342" value="" size="64">
</div>
::after
</li>
</ul>
</fieldset>
There are many of the <li> elements. I can't use the name or id as they dynamically created.
I want to target the textarea that says TARGET TEXTAREA. The only unqiquess I can find is the title attribute of the <a> element within the element.
I can get that specifically legend.name a[title*='Standout'] In Chrome Console: $$("legend.name a[title*='Standout']");
and I can traverse all the way to up to the <legend> element from the textarea legend.name ~ ul.elements li.element div.content textarea
In Chrome Console: $$("legend.name ~ ul.elements li.element div.content textarea")
That gives me ALL the textareas that have a div with class="content" that has a li with a class=element which has a ul with a class=elements which has a sibling legend with a class=name.
The only thing I can figure out is to add the qualifier that the legend with the class=name has to have the anchor that has 'Standout' in it's title.
I've tried $$("legend.name a[title*='Standout'] ~ ul.elements li.element div.content textarea") but that fails obviously since the anchor is not an adjacent sibling of the ul
Any help would be most appreciated!
Assume you have the following HTML:
<div id="root-component" class="script-component">a0
<div></div>
<div class="component">a2</div>
<div class="script-component">b
<div class="component">b1
<div class="script-component">c
</div>
<div class="component">b2
</div>
</div>
</div>
<div class="component">a3</div>
<div class="component">a4</div>
<div>
<div class="component">a5</div>
</div>
<div class="component"> a6
<div class="component">a7</div>
</div>
<div class="component">a8
<div class="script-component"></div>
</div>
</div>
From the root-component I would like to select all child elements with a component class until and not including the elements with the script-component class. This means at the end only the elements with an a text should be selected.
Edit: Or in Trung's words: The goal is to skip searching for components down the tree once script-component class is encountered.
Edit2: Or in even other words: I would like to select all .component children until a .script-component is encountered.

I have pagination problem. My api has a model product which contains a field which has 5 choices.
I have already entered 30 entries in product each choices has 6 entries, page size which I've set is 5, my requirement is if at first I call 127.0.0.1:8000/api/product/ I want 1 entry from each choice, no matter whether first page has only entries on choice 1.
I'm not sure this has to be done through pagination or filtering but I'm unable to figure it out.
class Product(models.Model):
item_category_choices = (('MU','Make Up'), ('SC','Skin Care'), ('Fra','Fragrance'), ('PC','Personal Care'),('HC','Hair Care'))
item_category = models.CharField(max_length=20,choices = item_category_choices)
now on hitting url /api/product I need a response something like
{"count":30,"next":"127.0.0:8000/api/product/?page=2","previous":null,"results":[{"id":1,"item_category":'Personal Care',},{"id":2,"item_category":'Hair Care'},{"id":3,"item_category":MakeUp},{"id":4,"item_category":"SkinCare},{"id":5,"item_category":"'Fragrance"}}]}
