[Note: edited to modernize ggplot syntax]

Your example is not reproducible since there is no ex1221new (there is an ex1221 in Sleuth2, so I guess that is what you meant). Also, you don't need (and shouldn't) pull columns out to send to ggplot. One advantage is that ggplot works with data.frames directly.

You can set the labels with xlab() and ylab(), or make it part of the scale_*.* call.

library("Sleuth2")
library("ggplot2")
ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area() + 
  xlab("My x label") +
  ylab("My y label") +
  ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area("Nitrogen") + 
  scale_x_continuous("My x label") +
  scale_y_continuous("My y label") +
  ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

An alternate way to specify just labels (handy if you are not changing any other aspects of the scales) is using the labs function

ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area() + 
  labs(size= "Nitrogen",
       x = "My x label",
       y = "My y label",
       title = "Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

which gives an identical figure to the one above.

Another option could be using automapper: You will be converting to any type from your anonymous returned object as long public properties matches. The key points are, returning object, use linq and autommaper. (or use similar idea returning serialized json, etc. or use reflection..)

using System.Linq;
using System.Reflection;
using AutoMapper;
using Microsoft.VisualStudio.TestTools.UnitTesting;
using Newtonsoft.Json;

namespace UnitTestProject1
{
    [TestClass]
    public class UnitTest1
    {
        [TestMethod]
        public void TestMethod1()
        {
            var data = GetData();

            var firts = data.First();

            var info = firts.GetType().GetProperties(BindingFlags.Instance | BindingFlags.Public).First(p => p.Name == "Name");
            var value = info.GetValue(firts);

            Assert.AreEqual(value, "One");
        }


        [TestMethod]
        public void TestMethod2()
        {
            var data = GetData();

            var config = new MapperConfiguration(cfg => cfg.CreateMissingTypeMaps = true);
            var mapper = config.CreateMapper();

            var users = data.Select(mapper.Map<User>).ToArray();

            var firts = users.First();

            Assert.AreEqual(firts.Name, "One");

        }

        [TestMethod]
        public void TestMethod3()
        {
            var data = GetJData();


            var users = JsonConvert.DeserializeObject<User[]>(data);

            var firts = users.First();

            Assert.AreEqual(firts.Name, "One");

        }

        private object[] GetData()
        {

            return new[] { new { Id = 1, Name = "One" }, new { Id = 2, Name = "Two" } };
        }

        private string GetJData()
        {

            return JsonConvert.SerializeObject(new []{ new { Id = 1, Name = "One" }, new { Id = 2, Name = "Two" } }, Formatting.None);
        }

        public class User
        {
            public int Id { get; set; }
            public string Name { get; set; }
        }
    }

}

Implicit waits are used to provide a default waiting time between each consecutive test step/command across the entire test script. Thus, subsequent test step would only execute when the specified amount of time have elapsed after executing the previous test step/command.

Explicit waits are used to halt the execution till the time a particular condition is met or the maximum time has elapsed. Unlike Implicit waits, Explicit waits are applied for a particular instance only.

The approach is wrong, you need to apply the border-radius to the container div instead of the actual image.

This would work:

.image-cropper {
  width: 100px;
  height: 100px;
  position: relative;
  overflow: hidden;
  border-radius: 50%;
}

img {
  display: inline;
  margin: 0 auto;
  height: 100%;
  width: auto;
}

<div class="image-cropper">
  <img src="https://via.placeholder.com/150" class="rounded" />
</div>

From Tomcat Documentation

maxConnections When this number has been reached, the server will accept, but not process, one further connection. once the limit has been reached, the operating system may still accept connections based on the acceptCount setting. (The maximum queue length for incoming connection requests when all possible request processing threads are in use. Any requests received when the queue is full will be refused. The default value is 100.) For BIO the default is the value of maxThreads unless an Executor is used in which case the default will be the value of maxThreads from the executor. For NIO and NIO2 the default is 10000. For APR/native, the default is 8192. Note that for APR/native on Windows, the configured value will be reduced to the highest multiple of 1024 that is less than or equal to maxConnections. This is done for performance reasons.

maxThreads
The maximum number of request processing threads to be created by this Connector, which therefore determines the maximum number of simultaneous requests that can be handled. If not specified, this attribute is set to 200. If an executor is associated with this connector, this attribute is ignored as the connector will execute tasks using the executor rather than an internal thread pool.

Your first formulation, image_url('logo.png'), is correct. If the image is found, it will generate the path /assets/logo.png (plus a hash in production). However, if Rails cannot find the image that you named, it will fall back to /images/logo.png.

The next question is: why isn't Rails finding your image? If you put it in app/assets/images/logo.png, then you should be able to access it by going to http://localhost:3000/assets/logo.png.

If that works, but your CSS isn't updating, you may need to clear the cache. Delete tmp/cache/assets from your project directory and restart the server (webrick, etc.).

If that fails, you can also try just using background-image: url(logo.png); That will cause your CSS to look for files with the same relative path (which in this case is /assets).

There are two different Lambda integrations you can configure in API Gateway, such as Lambda integration and Lambda proxy integration. For Lambda integration, you can customise what you are going to pass to Lambda in the payload that you don't need to parse the body, but when you are using Lambda Proxy integration in API Gateway, API Gateway will proxy everything to Lambda in payload like this,

{
    "message": "Hello me!",
    "input": {
        "path": "/test/hello",
        "headers": {

        "isBase64Encoded": false
    }
}

For the example you are referencing, it is not getting the body from the original request. It is constructing the response body back to API Gateway. It should be in this format,

{
    "statusCode": httpStatusCode,
    "headers": { "headerName": "headerValue", ... },
    "body": "...",
    "isBase64Encoded": false
}

Because the URL isn't on the same domain as your website, you need to use JSONP.

For example: (In jQuery):

$.getJSON(
    'http://soundcloud.com/oembed?url=http%3A//soundcloud.com/forss/flickermood&format=js&callback=?', 
    function(data) { ... }
);

This works by creating a <script> tag like this one:

<script src="http://soundcloud.com/oembed?url=http%3A//soundcloud.com/forss/flickermood&format=js&callback=someFunction" type="text/javascript"></script>

Their server then emits Javascript that calls someFunction with the data to retrieve.
`someFunction is an internal callback generated by jQuery that then calls your callback.

Very Simplest Method:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, 
                                                     NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

NSFileManager *manager = [NSFileManager defaultManager];
NSArray *fileList = [manager contentsOfDirectoryAtPath:documentsDirectory 
                                                 error:nil];
//--- Listing file by name sort
NSLog(@"\n File list %@",fileList);

//---- Sorting files by extension    
NSArray *filePathsArray = 
  [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:documentsDirectory  
                                                      error:nil];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF EndsWith '.png'"];
filePathsArray =  [filePathsArray filteredArrayUsingPredicate:predicate];
NSLog(@"\n\n Sorted files by extension %@",filePathsArray);

Yet Another Option:

>>> [re.split(r'(\d+)', s) for s in ('foofo21', 'bar432', 'foobar12345')]
[['foofo', '21', ''], ['bar', '432', ''], ['foobar', '12345', '']]

if you are using an IDE like visual studio and it is open while you sending commands close IDE and try again

git add .

and other commands, it will workout

Use the pip application. On windows you find it in Python3/Scripts/pip.exe and On Ubuntu you can install with apt-get install python3-pip. and so, use the command line:

pip3 install --upgrade pip

pip3 install opencv-python

On Windows use only pip.exe instead pip3

You can display the name of a variable by using the preprocessor. For instance

#include <iostream>
#define quote(x) #x
class one {};
int main(){
    one A;
    std::cout<<typeid(A).name()<<"\t"<< quote(A) <<"\n";
    return 0;
}

outputs

3one    A

on my machine. The # changes a token into a string, after preprocessing the line is

std::cout<<typeid(A).name()<<"\t"<< "A" <<"\n";

Of course if you do something like

void foo(one B){
    std::cout<<typeid(B).name()<<"\t"<< quote(B) <<"\n";
}
int main(){
    one A;
    foo(A);
    return 0;
}

you will get

3one B

as the compiler doesn't keep track of all of the variable's names.

As it happens in gcc the result of typeid().name() is the mangled class name, to get the demangled version use

#include <iostream>
#include <cxxabi.h>
#define quote(x) #x
template <typename foo,typename bar> class one{ };
int main(){
    one<int,one<double, int> > A;
    int status;
    char * demangled = abi::__cxa_demangle(typeid(A).name(),0,0,&status);
    std::cout<<demangled<<"\t"<< quote(A) <<"\n";
    free(demangled);
    return 0;
}

which gives me

one<int, one<double, int> > A

Other compilers may use different naming schemes.

Extending @RobBednark's solution to a specific Windows + PuTTY scenario, you can do so:

1. Generate SSH key pair with PuTTYgen (following Manually generating your SSH key in Windows), saving it to a PPK file;

2. With the context menu in Windows Explorer, choose Edit with PuTTYgen. It will prompt for a password.

If you type the wrong password, it will just prompt again.

Note, if you like to type, use the following command on a folder that contains the PPK file: puttygen private-key.ppk -y.

CREATE LOGIN AdminLOGIN WITH PASSWORD = 'pass'
GO


Use MyDatabase;
GO

IF NOT EXISTS (SELECT * FROM sys.database_principals WHERE name = N'AdminLOGIN')
BEGIN
    CREATE USER [AdminLOGIN] FOR LOGIN [AdminLOGIN]
    EXEC sp_addrolemember N'db_owner', N'AdminLOGIN'
    EXEC master..sp_addsrvrolemember @loginame = N'adminlogin', @rolename = N'sysadmin'
END;
GO

this full help you for network using:

1- Right-click on SQL Server instance at root of Object Explorer, click on Properties
Select Security from the left pane.

2- Select the SQL Server and Windows Authentication mode radio button, and click OK.

3- Right-click on the SQL Server instance, select Restart (alternatively, open up Services and restart the SQL Server service).

4- Close sql server application and reopen it

5- open 'SQL Server Configuration Manager' and tcp enabled for network

6-Double-click the TCP/IP protocol, go to the IP Addresses tab and scroll down to the IPAll section.

7-Specify the 1433 in the TCP Port field (or another port if 1433 is used by another MSSQL Server) and press the OK 

8-Open in Sql Server: Security And Login  And Right Click on Login Name And Select Peroperties And Select Server Roles And 
  Checked The Sysadmin And Bulkadmin then Ok.
9-firewall: Open cmd as administrator and type: 
      netsh firewall set portopening protocol = TCP port = 1433 name = SQLPort mode = ENABLE scope = SUBNET profile = CURRENT

You can use:

NOW() + INTERVAL 1 DAY

If you are only interested in the date, not the date and time then you can use CURDATE instead of NOW:

CURDATE() + INTERVAL 1 DAY

If your markup is bound to a controller, directive or anything else with a $scope:

console.log($scope.movie);

You can use java.io.InputStream to read the file as shown below:

InputStream inputStream = getClass().getClassLoader().getResourceAsStream(myProps.properties); 

You have to create the colors.xml file in the res/values folder of your project. The code of colors.xml is

<?xml version="1.0" encoding="utf-8"?>
<resources>
 <color name="orange">#ff5500</color>
 <color name="white">#ffffff</color>
 <color name="transparent">#00000000</color>
 <color name="date_color">#999999</color>
 <color name="black">#000000</color>
 <color name="gray">#999999</color>
 <color name="blue">#0066cc</color>
 <color name="gold">#e6b121</color>
 <color name="blueback">#99FFFF</color>
 <color name="articlecolor">#3399FF</color> 
 <color name="article_title">#3399FF</color> 
 <color name="cachecolor">#8ad0e8</color>
</resources>

Or, you can use Colors in your application by following way

android.graphics.Color.TRANSPARENT;

Similarly

android.graphics.Color.RED;

string[] allfiles = Directory.GetFiles("path/to/dir", "*.*", SearchOption.AllDirectories);

where *.* is pattern to match files

If the Directory is also needed you can go like this:

 foreach (var file in allfiles){
     FileInfo info = new FileInfo(file);
 // Do something with the Folder or just add them to a list via nameoflist.add();
 }

The current recommended way is with the flask command line utility.

https://flask.palletsprojects.com/en/1.1.x/quickstart/#debug-mode

Example:

$ export FLASK_APP=main.py
$ export FLASK_ENV=development
$ flask run

or in one command:

$ FLASK_APP=main.py FLASK_ENV=development flask run

If you want different port than the default (5000) add --port option.

Example:

$ FLASK_APP=main.py FLASK_ENV=development flask run --port 8080

More options are available with:

$ flask run --help

FLASK_APP can also be set to module:app or module:create_app instead of module.py. See https://flask.palletsprojects.com/en/1.1.x/cli/#application-discovery for a full explanation.

Use break; and this will exit the foreach loop

In JavaScript 1.8.5, Object.getOwnPropertyNames returns an array of all properties found directly upon a given object.

Object.getOwnPropertyNames ( obj )

and another method Object.keys, which returns an array containing the names of all of the given object's own enumerable properties.

Object.keys( obj )

I used forEach to list values and keys in obj, same as for (var key in obj) ..

Object.keys(obj).forEach(function (key) {
      console.log( key , obj[key] );
});

This all are new features in ECMAScript , the mothods getOwnPropertyNames, keys won't supports old browser's.

add 0.5 before casting (if x > 0) or subtract 0.5 (if x < 0), because the compiler will always truncate.

float x = 55; // stored as 54.999999...
x = x + 0.5 - (x<0); // x is now 55.499999...
int y = (int)x; // truncated to 55

C++11 also introduces std::round, which likely uses a similar logic of adding 0.5 to |x| under the hood (see the link if interested) but is obviously more robust.

A follow up question might be why the float isn't stored as exactly 55. For an explanation, see this stackoverflow answer.

Try setting position to absolute, ie.

#yourDiv{
    position: absolute;
    z-index: 10;
};

It is the fault of Do.Something(). The best practice here would be to return an array of size 0 (that is possible) instead of a null.

The :active pseudo-class is not the same as adding a class to style the element.

The :active CSS pseudo-class represents an element (such as a button) that is being activated by the user. When using a mouse, "activation" typically starts when the mouse button is pressed down and ends when it is released.

What we are looking for is a class, such as .active, which we can use to style the navigation item.

For a clearer example of the difference between :active and .active see the following snippet:

li:active {_x000D_
  background-color: #35495E;_x000D_
}_x000D_
_x000D_
li.active {_x000D_
  background-color: #41B883;_x000D_
}

<ul>_x000D_
  <li>:active (pseudo-class) - Click me!</li>_x000D_
  <li class="active">.active (class)</li>_x000D_
</ul>

Vue-Router

vue-router automatically applies two active classes, .router-link-active and .router-link-exact-active, to the <router-link> component.

router-link-active

This class is applied automatically to the <router-link> component when its target route is matched.

The way this works is by using an inclusive match behavior. For example, <router-link to="/foo"> will get this class applied as long as the current path starts with /foo/ or is /foo.

So, if we had <router-link to="/foo"> and <router-link to="/foo/bar">, both components would get the router-link-active class when the path is /foo/bar.

router-link-exact-active

This class is applied automatically to the <router-link> component when its target route is an exact match. Take into consideration that both classes, router-link-active and router-link-exact-active, will be applied to the component in this case.

Using the same example, if we had <router-link to="/foo"> and <router-link to="/foo/bar">, the router-link-exact-activeclass would only be applied to <router-link to="/foo/bar"> when the path is /foo/bar.

The exact prop

Lets say we have <router-link to="/">, what will happen is that this component will be active for every route. This may not be something that we want, so we can use the exact prop like so: <router-link to="/" exact>. Now the component will only get the active class applied when it is an exact match at /.

CSS

We can use these classes to style our element, like so:

 nav li:hover,
 nav li.router-link-active,
 nav li.router-link-exact-active {
   background-color: indianred;
   cursor: pointer;
 }

The <router-link> tag was changed using the tag prop, <router-link tag="li" />.

Change default classes globally

If we wish to change the default classes provided by vue-router globally, we can do so by passing some options to the vue-router instance like so:

const router = new VueRouter({
  routes,
  linkActiveClass: "active",
  linkExactActiveClass: "exact-active",
})

Change default classes per component instance (<router-link>)

If instead we want to change the default classes per <router-link> and not globally, we can do so by using the active-class and exact-active-class attributes like so:

<router-link to="/foo" active-class="active">foo</router-link>

<router-link to="/bar" exact-active-class="exact-active">bar</router-link>

v-slot API

Vue Router 3.1.0+ offers low level customization through a scoped slot. This comes handy when we wish to style the wrapper element, like a list element <li>, but still keep the navigation logic in the anchor element <a>.

<router-link
  to="/foo"
  v-slot="{ href, route, navigate, isActive, isExactActive }"
>
  <li
    :class="[isActive && 'router-link-active', isExactActive && 'router-link-exact-active']"
  >
    <a :href="href" @click="navigate">{{ route.fullPath }}</a>
  </li>
</router-link>

module Enumerable
  def map_with_index(&block)
    i = 0
    self.map { |val|
      val = block.call(val, i)
      i += 1
      val
    }
  end
end

["foo", "bar"].map_with_index {|item, index| [item, index] } => [["foo", 0], ["bar", 1]]

Actually, all of those examples on the web wherein the common content/file type like "js", "css", "img", etc is been used as library name are misleading.

Real world examples

To start, let's look at how existing JSF implementations like Mojarra and MyFaces and JSF component libraries like PrimeFaces and OmniFaces use it. No one of them use resource libraries this way. They use it (under the covers, by @ResourceDependency or UIViewRoot#addComponentResource()) the following way:

<h:outputScript library="javax.faces" name="jsf.js" />
<h:outputScript library="primefaces" name="jquery/jquery.js" />
<h:outputScript library="omnifaces" name="omnifaces.js" />
<h:outputScript library="omnifaces" name="fixviewstate.js" />
<h:outputScript library="omnifaces.combined" name="[dynamicname].js" />
<h:outputStylesheet library="primefaces" name="primefaces.css" />
<h:outputStylesheet library="primefaces-aristo" name="theme.css" />
<h:outputStylesheet library="primefaces-vader" name="theme.css" />

It should become clear that it basically represents the common library/module/theme name where all of those resources commonly belong to.

Easier identifying

This way it's so much easier to specify and distinguish where those resources belong to and/or are coming from. Imagine that you happen to have a primefaces.css resource in your own webapp wherein you're overriding/finetuning some default CSS of PrimeFaces; if PrimeFaces didn't use a library name for its own primefaces.css, then the PrimeFaces own one wouldn't be loaded, but instead the webapp-supplied one, which would break the look'n'feel.

Also, when you're using a custom ResourceHandler, you can also apply more finer grained control over resources coming from a specific library when library is used the right way. If all component libraries would have used "js" for all their JS files, how would the ResourceHandler ever distinguish if it's coming from a specific component library? Examples are OmniFaces CombinedResourceHandler and GraphicResourceHandler; check the createResource() method wherein the library is checked before delegating to next resource handler in chain. This way they know when to create CombinedResource or GraphicResource for the purpose.

Noted should be that RichFaces did it wrong. It didn't use any library at all and homebrewed another resource handling layer over it and it's therefore impossible to programmatically identify RichFaces resources. That's exactly the reason why OmniFaces CombinedResourceHander had to introduce a reflection-based hack in order to get it to work anyway with RichFaces resources.

Your own webapp

Your own webapp does not necessarily need a resource library. You'd best just omit it.

<h:outputStylesheet name="css/style.css" />
<h:outputScript name="js/script.js" />
<h:graphicImage name="img/logo.png" />

Or, if you really need to have one, you can just give it a more sensible common name, like "default" or some company name.

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

Or, when the resources are specific to some master Facelets template, you could also give it the name of the template, so that it's easier to relate each other. In other words, it's more for self-documentary purposes. E.g. in a /WEB-INF/templates/layout.xhtml template file:

<h:outputStylesheet library="layout" name="css/style.css" />
<h:outputScript library="layout" name="js/script.js" />

And a /WEB-INF/templates/admin.xhtml template file:

<h:outputStylesheet library="admin" name="css/style.css" />
<h:outputScript library="admin" name="js/script.js" />

For a real world example, check the OmniFaces showcase source code.

Or, when you'd like to share the same resources over multiple webapps and have created a "common" project for that based on the same example as in this answer which is in turn embedded as JAR in webapp's /WEB-INF/lib, then also reference it as library (name is free to your choice; component libraries like OmniFaces and PrimeFaces also work that way):

<h:outputStylesheet library="common" name="css/style.css" />
<h:outputScript library="common" name="js/script.js" />
<h:graphicImage library="common" name="img/logo.png" />

Library versioning

Another main advantage is that you can apply resource library versioning the right way on resources provided by your own webapp (this doesn't work for resources embedded in a JAR). You can create a direct child subfolder in the library folder with a name in the \d+(_\d+)* pattern to denote the resource library version.

WebContent
 |-- resources
 |    `-- default
 |         `-- 1_0
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

When using this markup:

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

This will generate the following HTML with the library version as v parameter:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_0" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_0"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_0" alt="" />

So, if you have edited/updated some resource, then all you need to do is to copy or rename the version folder into a new value. If you have multiple version folders, then the JSF ResourceHandler will automatically serve the resource from the highest version number, according to numerical ordering rules.

So, when copying/renaming resources/default/1_0/* folder into resources/default/1_1/* like follows:

WebContent
 |-- resources
 |    `-- default
 |         |-- 1_0
 |         |    :
 |         |
 |         `-- 1_1
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

Then the last markup example would generate the following HTML:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_1" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_1"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_1" alt="" />

This will force the webbrowser to request the resource straight from the server instead of showing the one with the same name from the cache, when the URL with the changed parameter is been requested for the first time. This way the endusers aren't required to do a hard refresh (Ctrl+F5 and so on) when they need to retrieve the updated CSS/JS resource.

Please note that library versioning is not possible for resources enclosed in a JAR file. You'd need a custom ResourceHandler. See also How to use JSF versioning for resources in jar.

In my case, this error:

Was due to the CSP in my .htaccess that did not allow the content to be loaded. You can check this by opening the browser's console and refreshing the page.

Once I added the domain that was hosting the video in the media-src part of that CSP, the console was clean and the video was loaded properly. Example:

You can customize a project's Git config by changing the repository specific configuration file (i.e. /path/to/repo/.git/config). BTW, git config writes to this file by default:

cd /path/to/repo
git config user.name 'John Doe'  # sets user.name locally for the repo

I prefer to create separate profiles for different projects (e.g. in ~/.gitconfig.d/) and then include them in the repository's config file:

cd /path/to/repo
git config include.path '~/.gitconfig.d/myproject.conf'

This works well if you need to use the same set of options in multiple repos that belong to a single project. You can also set up shell aliases or a custom Git command to manipulate the profiles.

Last-Modified : The last modified date for the requested object

If-Modified-Since : Allows a 304 Not Modified to be returned if last modified date is unchanged.

ETag : An ETag is an opaque identifier assigned by a web server to a specific version of a resource found at a URL. If the resource representation at that URL ever changes, a new and different ETag is assigned.

If-None-Match : Allows a 304 Not Modified to be returned if ETag is unchanged.

the browser store cache with a date(Last-Modified) or id(ETag), when you need to request the URL again, the browser send request message with the header:

the server will return 304 when the if statement is False, and browser will use cache.

(Your question is still unclear on whether your code is calling printStackTrace() or this is being done by a logging handler.)

Here are some possible explanations about what might be happening:

• The logger / handler being used has been configured to only output the exception's message string, not a full stack trace.

• Your application (or some third-party library) is logging the exception using LOG.error(ex); rather than the 2-argument form of (for example) the log4j Logger method.

• The message is coming from somewhere different to where you think it is; e.g. it is actually coming some third-party library method, or some random stuff left over from earlier attempts to debug.

• The exception that is being logged has overloaded some methods to obscure the stacktrace. If that is the case, the exception won't be a genuine NullPointerException, but will be some custom subtype of NPE or even some unconnected exception.

I think that the last possible explanation is pretty unlikely, but people do at least contemplate doing this kind of thing to "prevent" reverse engineering. Of course it only really succeeds in making life difficult for honest developers.

        var q = Request.QueryString;
        NameValueCollection qscoll = HttpUtility.ParseQueryString(q.ToString());

Using Gson, you can do the following:

    jsonString, new TypeToken<HashMap<String, Object>>() {}.getType()
);

I've just tried that myself, and it gave me a 200 OK response, but no content - the content length was 0. Are you sure it's giving you content? Anyway, I'll assume that you've really got content.

Getting actual text back relies on knowing the encoding, which can be tricky. It should be in the Content-Type header, but then you've got to parse it etc.

However, if this is actually XML (e.g. from "http://google.com/xrds/xrds.xml"), it's a lot easier. Just load the XML into memory, e.g. via LINQ to XML. For example:

using System;
using System.IO;
using System.Net;
using System.Xml.Linq;
using System.Web;

class Test
{
    static void Main()
    {
        string url = "http://google.com/xrds/xrds.xml";
        HttpWebRequest request = (HttpWebRequest) WebRequest.Create(url);

        XDocument doc;
        using (WebResponse response = request.GetResponse())
        {
            using (Stream stream = response.GetResponseStream())
            {
                doc = XDocument.Load(stream);
            }
        }
        // Now do whatever you want with doc here
        Console.WriteLine(doc);
    }   
}

If the content is XML, getting the result into an XML object model (whether it's XDocument, XmlDocument or XmlReader) is likely to be more valuable than having the plain text.

FileNotFound in this case means you got a 404 from your server - could it be that the server does not like "POST" requests?

You can get active store information like this:

It's not a query waiting for connection; it's a connection pointer waiting for the timeout to terminate.

It doesn't have an impact on performance. The only thing it's using is a few bytes as every connection does.

The really worst case: It's using one connection of your pool; If you would connect multiple times via console client and just close the client without closing the connection, you could use up all your connections and have to wait for the timeout to be able to connect again... but this is highly unlikely :-)

See MySql Proccesslist filled with "Sleep" Entries leading to "Too many Connections"? and https://dba.stackexchange.com/questions/1558/how-long-is-too-long-for-mysql-connections-to-sleep for more information.

You can use Get External Data (dispite its name), located in the 'Data' tab of Excel 2010, to set up a connection in a workbook to query data from itself. Use From Other Sources From Microsoft Query to connect to Excel

Once set up you can use VBA to manipulate the connection to, among other thing, view and modify the SQL command that drives the query. This query does reference the in memory workbook, so doen't require a save to refresh the latest data.

Here's a quick Sub to demonstrate accessing the connection objects

Sub DemoConnection()
    Dim c As Connections
    Dim wb As Workbook
    Dim i As Long
    Dim strSQL As String

    Set wb = ActiveWorkbook
    Set c = wb.Connections
    For i = 1 To c.Count
        ' Reresh the data
        c(i).Refresh 
        ' view the SQL query
        strSQL = c(i).ODBCConnection.CommandText
        MsgBox strSQL
    Next
End Sub

Just adding to the above answer, In a web application @valid is used where the bean to be validated is also annotated with validation annotations e.g. @NotNull, @Email(hibernate annotation) so when while getting input from user the values can be validated and binding result will have the validation results. bindingResult.hasErrors() will tell if any validation failed.

It is not possible to add comments to 'normal' Access queries, that is, a QueryDef in an mdb, which is why a number of people recommend storing the sql for queries in a table.

Try to use pseudo classes like :first-child & :last-child to remove extra padding from first & last child.

Inspect the generated code of slick slider & try to remove padding on that.

Colin is correct that a profile should be used. However, his answer hard-codes the target directory in the profile. An alternate solution would be to add a profile like this:

    <profile>
        <id>alternateBuildDir</id>
        <activation>
            <property>
                <name>alt.build.dir</name>
            </property>
        </activation>
        <build>
            <directory>${alt.build.dir}</directory>
        </build>
    </profile>

Doing so would have the effect of changing the build directory to whatever is given by the alt.build.dir property, which can be given in a POM, in the user's settings, or on the command line. If the property is not present, the compilation will happen in the normal target directory.

1st Step : Go for the workstation In my case -> cd /c/Users/rashni/MyWS/WSpace

3rd step : use command In my case -> git config --global user.name "rashni" In my case -> git config --global user.email [email protected]

4th step : To check all configuration(optional) In my case -> git config --list

Not sure static variables are cached in thread local memory or NOT. But when I executed two threads(T1,T2) accessing same object(obj) and when update made by T1 thread to static variable it got reflected in T2.

In my case the problem was that both port 80 and 443 were in use: Steps to use to fix it are :

1. Open xampp and click on config button
2. Now click on ( Appache )httpd.conf (Open in notepad or other editor)
3. Now click ctrl + h.
4. Find 80 and replace with 8080
5. Now save and now click on Appache(httpd-ssl.conf).
6. Now find 443 and replace with 4430.
7. Now your xampp must be working fine as both these code are never in use by other programs on your system.

Now your localhost will be available as localhost:8080

This is how I've achieved in Reactjs.

Main problem were ratio and scale If you do a quick window.devicePixelRatio, it's default value is 2 which was causing the half image issue.

const printDocument = () => {
  const input = document.getElementById('divToPrint');
  const divHeight = input.clientHeight
  const divWidth = input.clientWidth
  const ratio = divHeight / divWidth;

  html2canvas(input, { scale: '1' }).then((canvas) => {
    const imgData = canvas.toDataURL('image/jpeg');
    const pdfDOC = new JSPDF("l", "mm", "a0"); //  use a4 for smaller page

    const width = pdfDOC.internal.pageSize.getWidth();
    let height = pdfDOC.internal.pageSize.getHeight();
    height = ratio * width;

    pdfDOC.addImage(imgData, 'JPEG', 0, 0, width - 20, height - 10);
    pdfDOC.save('summary.pdf');   //Download the rendered PDF.
  })
}

In Laravel 5.5

Working on a similar issue and setting the middleware argument from guest to 'auth' seemed like a more elegant solution.

Edit File: app->http->Controllers->Auth->RegisterController.php

public function __construct()
{
     //replace this
     //$this->middleware('guest');

     //with this argument.
       $this->middleware('auth');
}

I could be wrong though...but it seems more slick than editing the routing with more lines and less shity than simply redirecting the page...at least in this instance, wanting to lock down the registration for guests.

99% of the time I would use XMLHttpRequest or fetch for something like this. However, there's an alternative solution which doesn't require javascript...

You could include a hidden iframe on your page and set the target attribute of your form to point to that iframe.

<style>
  .hide { position:absolute; top:-1px; left:-1px; width:1px; height:1px; }
</style>

<iframe name="hiddenFrame" class="hide"></iframe>

<form action="receiver.pl" method="post" target="hiddenFrame">
  <input name="signed" type="checkbox">
  <input value="Save" type="submit">
</form>

There are very few scenarios where I would choose this route. Generally handling it with javascript is better because, with javascript you can...

• gracefully handle errors (e.g. retry)
• provide UI indicators (e.g. loading, processing, success, failure)
• run logic before the request is sent, or run logic after the response is received.

Swift 3 class:

import UIKit

class CircleView: UIView {

    override func draw(_ rect: CGRect) {
        guard let context = UIGraphicsGetCurrentContext() else {return}
        
        context.addEllipse(in: rect)
        context.setFillColor(UIColor.blue.cgColor)
        context.fillPath()
    }           
}

This will do it:

window.history.pushState(null,null,'https://www.google.com');

After going through a few free e-books, I found the best book for learning to program was Head First Programming published by O'Reily Press. It uses Python as the language and gives you programs to work on from the very start. They are all more interesting that 'Hello World'. It's well worth the money I spent on it, and since it's been out for a bit you may be able to find a cheaper used copy on Ebay or Amazon.

You simply can't.

bcrypt uses salting, of different rounds, I use 10 usually.

bcrypt.hash(req.body.password,10,function(error,response){ }

This 10 is salting random string into your password.

Supposing d is your list of dicts, simply:

df = pd.DataFrame(d)

Note: this does not work with nested data.

You could also do this

#include <comdef.h>

BSTR bs = SysAllocString("Hello");
std::wstring myString = _bstr_t(bs, false); // will take over ownership, so no need to free

or std::string if you prefer

EDIT: if your original string contains multiple embedded \0 this approach will not work.

To get the value:

$query = $this->db->query("YOUR QUERY");

Then, for single row from(in controller):

$query1 = $query->row();
$data['product'] = $query1;

In view, you can use your own code (above code)

You won't be able to get all types in a namespace, because a namespace can bridge multiple assemblies, but you can get all classes in an assembly and check to see if they belong to that namespace.

Assembly.GetTypes() works on the local assembly, or you can load an assembly first then call GetTypes() on it.

When installing VMware Tools on a Windows Guest, “Time Synchronisation” is not enabled by default. However – “best practise” is to enable time synch on Windows Guests.

There a several ways to do this from outside the VM, but I wanted to find a way to enable time sync from within the guest itself either on or after tools install.

Surprisingly, this wasn’t quite as straightforward as I expected. (I assumed it would be posible to set this as a parameter / config option during tools install)

After a bit of searching I found a way to do this in a VMware article called “Using the VMware Tools Command-Line Interface“.

So, if time sync is disabled, you can enable it by running the following command line in the guest:

      VMwareService.exe –cmd “vmx.set_option synctime 0 1"

Additional Notes

For some (IMHO stupid) reason, this utility requires you to specify the current as well as the new value

0 = disabled 1 = enabled

So – if you run this command on a machine which has this already set, you will get an error saying – “Invalid old value“. Obviously you can “ignore” this error when run (so not a huge deal) but the current design seems a bit dumb. IMHO it would be much more sensible if you could simply specify the value you want to set and not require the current value to be specified.

i.e. VMwareService.exe –cmd “vmx.set_option synctime <0|1>”

Why not use commands.getoutput() instead?

import commands

text = "Mario Balotelli" 
output = 'espeak "%s"' % text
print text
a = commands.getoutput(output)

Match against one class that has whitespace.

<div class="hello "></div>

//div[normalize-space(@class)="hello"]

The question is answered already, but I want add more information about the causes.

Some Common Mistakes.

1.findViewById() of non existing view

Like when you use findViewById(R.id.button) when button id does not exist in layout XML.

2. Wrong cast.

If you wrong cast some class, then you get this error. Like you cast RelativeLayout to LinearLayout or EditText to TextView.

3. Activity not registered in manifest.xml

If you did not register Activity in manifest.xml then this error comes.

4. findViewById() with declaration at top level

Below code is incorrect. This will create error. Because you should do findViewById() after calling setContentView(). Because an View can be there after it is created.

public class MainActivity extends Activity {

  ImageView mainImage = (ImageView) findViewById(R.id.imageViewMain); //incorrect way

  @Override
  protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mainImage = (ImageView) findViewById(R.id.imageViewMain); //correct way
    //...
  }
}

5. Starting abstract Activity class.

When you try to start an Activity which is abstract, you will will get this error. So just remove abstract keyword before activity class name.

6. Using kotlin but kotlin not configured.

If your activity is written in Kotlin and you have not setup kotlin in your app. then you will get error. You can follow simple steps as written in Android Link or Kotlin Link. You can check this answer too.

How to register activity in manifest

How about grepping for that line then using awk

version=$(awk -F "=" '/database_version/ {print $2}' parameters.ini)

You have to change the extends Activity to extends AppCompactActivity then try set and getSupportActionBar()

this code works with me

 ImageView carView = (ImageView) v.findViewById(R.id.car_icon);

                            byte[] decodedString = Base64.decode(picture, Base64.NO_WRAP);
                            InputStream input=new ByteArrayInputStream(decodedString);
                            Bitmap ext_pic = BitmapFactory.decodeStream(input);
                            carView.setImageBitmap(ext_pic);

The ThreadLocal class in Java enables you to create variables that can only be read and written by the same thread. Thus, even if two threads are executing the same code, and the code has a reference to a ThreadLocal variable, then the two threads cannot see each other's ThreadLocal variables.

I give you The Function parse_params that will parse params from the command line.

1. It is a pure Bash solution, no additional utilities.
2. Does not pollute global scope.
3. Effortlessly returns you simple to use variables, that you could build further logic on.
4. Amount of dashes before params does not matter (--all equals -all equals all=all)

The script below is a copy-paste working demonstration. See show_use function to understand how to use parse_params.

Limitations:

1. Does not support space delimited params (-d 1)
2. Param names will lose dashes so --any-param and -anyparam are equivalent
3. eval $(parse_params "$@") must be used inside bash function (it will not work in the global scope)

#!/bin/bash

# Universal Bash parameter parsing
# Parse equal sign separated params into named local variables
# Standalone named parameter value will equal its param name (--force creates variable $force=="force")
# Parses multi-valued named params into an array (--path=path1 --path=path2 creates ${path[*]} array)
# Puts un-named params as-is into ${ARGV[*]} array
# Additionally puts all named params as-is into ${ARGN[*]} array
# Additionally puts all standalone "option" params as-is into ${ARGO[*]} array

I had the same problem and resolved by pressing Ctrl + R , Ctrl + W.

This is the first working version of what will be a GPS reader and data presenter. tkinter is a very fragile thing with way too few error messages. It does not put stuff up and does not tell why much of the time. Very difficult coming from a good WYSIWYG form developer. Anyway, this runs a small routine 10 times a second and presents the information on a form. Took a while to make it happen. When I tried a timer value of 0, the form never came up. My head now hurts! 10 or more times per second is good enough for me. I hope it helps someone else. Mike Morrow

Don't run this command on shell, enter this script at a command prompt with your database name, collection name, and file name, all replacing the placeholders..

mongoexport --db (Database name) --collection (Collection Name) --out (File name).json

It works for me.

It's a default font on Macs, but rare on PCs. Since it's not technically web-safe, some people may have it and some people may not. If you want to use a font like that, without using @font-face, you may want to write it out several different ways because it might not work the same for everyone.

I like using a font stack that touches on all bases like this:

font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", 
  Helvetica, Arial, "Lucida Grande", sans-serif;

This recommended font-family stack is further described in this CSS-Tricks snippet Better Helvetica which uses a font-weight: 300; as well.

Python's if can be used as a ternary operator:

>>> 'true' if True else 'false'
'true'
>>> 'true' if False else 'false'
'false'

Well, you have multiple ways to do this: -if you don't have any data on your table, just drop it and create it again.

Dropping the existing field and creating it again like this

ALTER TABLE test DROP PRIMARY KEY, DROP test_id, ADD test_id int AUTO_INCREMENT NOT NULL FIRST, ADD PRIMARY KEY (test_id);

Or just modify it

ALTER TABLE test MODIFY test_id INT AUTO_INCREMENT NOT NULL, ADD PRIMARY KEY (test_id);

As per my research I found that WebClient.DownloadFileAsync is the best way to download file. It is available in System.Net namespace and it supports .net core as well.

Here is the sample code to download the file.

using System;
using System.IO;
using System.Net;
using System.ComponentModel;

public class Program
{
    public static void Main()
    {
        new Program().Download("ftp://localhost/test.zip");
    }
    public void Download(string remoteUri)
    {
        string FilePath = Directory.GetCurrentDirectory() + "/tepdownload/" + Path.GetFileName(remoteUri); // path where download file to be saved, with filename, here I have taken file name from supplied remote url
        using (WebClient client = new WebClient())
        {

just wanna add another easy way to do this: If your ImageButton remains its background and you don't set it to null, it will work like a normal button and will show the click animation while clicking exactly like other buttons.The way to hide the background while it is still there:

<ImageButton
    android:id="@+id/imageButton2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingBottom="1dp"
    android:paddingLeft="1dp"
    android:paddingRight="1dp"
    android:paddingTop="1dp"
    android:src="@drawable/squareicon" />

The paddings won't let the background be visible and make the button act like other buttons.

Interesting. How are you generating your JSON on the server end? Are you using a library function (such as json_encode in PHP), or are you building the JSON string by hand?

The only thing that grabs my attention is the escape apostrophe (\'). Seeing as you're using double quotes, as you indeed should, there is no need to escape single quotes. I can't check if that is indeed the cause for your jQuery error, as I haven't updated to version 1.4.1 myself yet.

Setting "skipLibCheck": true in tsconfig.json solved my problem

"compilerOptions": {
    "skipLibCheck": true
}

I agree with Kevin B, the bug report says it all. It sounds like you are trying to make cross-domain ajax calls. If you're not familiar with the same origin policy you can start here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Same_origin_policy_for_JavaScript.

If this is not intended to be a cross-domain ajax call, try making your target url relative and see if the problem goes away. If you're really desperate look into the JSONP, but beware, mayhem lurks. There really isn't much more we can do to help you.

loop through all loaded assemblies, loop through all their types, and check if they implement the interface.

something like:

Type ti = typeof(IYourInterface);
foreach (Assembly asm in AppDomain.CurrentDomain.GetAssemblies()) {
    foreach (Type t in asm.GetTypes()) {
        if (ti.IsAssignableFrom(t)) {
            // here's your type in t
        }
    }
}

tl;dr You might not need to whack your entire NetBeans cache.

My problem manifested as running a clean build didn't delete the previous build folder or testuserdir folder, while I was using NetBeans 8.0.2.

The first time I had this problem, Ray Slater's answer above helped me immensely. I had two Project Groups, and had to close each project in both groups, close NetBeans, clear the cache, then add my projects back to my groups before it would work again.

Later, this problem cropped up again with NetBeans 8.1. I closed NetBeans, and ran ant build clean at the command line, and it worked. When I reopened NetBeans, the problem was resolved. It occurs to me that NetBeans was keeping something open and just needed to be closed in order to delete the folders.

Update
I finally figured out what was going on. Somehow, my NetBeans "Module Suite Project" (yellow/orange puzzle pieces icon) had been closed and the "Module Project" (purple puzzle piece icon) having the same exact name as the "Module Suite Project" was open. Building clean cleaned that particular Project correctly, but did not clean the entire Suite.

Now that I have the "Module Suite Project" opened correctly again, things work as expected. This explains why ant build clean worked, since it was done on the command line at the right level to clean the whole Suite.

I suspect I didn't strictly need to clean out my NetBeans cache at all though perhaps doing so actually fixed the issue of why it was only showing the "Module Project" instead of the "Module Suite Project", thereby doing the right thing when I clicked build clean... If I had simply realized that the Suite was no longer open and only the Project was, I could have fixed it in three seconds.

If you want to alter order for columns in Sql server, There is no direct way to do this in SQL Server currently.

Have a look at http://blog.sqlauthority.com/2008/04/08/sql-server-change-order-of-column-in-database-tables/

You can change order while edit design for table.

Well I found this way :

Oracle SQL Developer (Left top icon) > Preferences > Database > NLS and set the Date Format as MM/DD/YYYY HH24:MI:SS

I was looking for a solution for this for a long time and found most of the answers are not working or not suitable for my situation i also find most of the java script code for that they worked but only with the vertical scroll not with the horizontal scroll and also combination of header and rows doesn't match.

Finally i have found a solution with javascript here is the link bellow :-

scrollable horizontal and vertical grid view with fixed headers

To obtain all the column names of a DataFrame, df_data in this example, you just need to use the command df_data.columns.values. This will show you a list with all the Column names of your Dataframe

Code:

df_data=pd.read_csv('../input/data.csv')
print(df_data.columns.values)

Output:

['PassengerId' 'Survived' 'Pclass' 'Name' 'Sex' 'Age' 'SibSp' 'Parch' 'Ticket' 'Fare' 'Cabin' 'Embarked']

Informally

entropy is availability of information or knowledge, Lack of information will leads to difficulties in prediction of future which is high entropy (next word prediction in text mining) and availability of information/knowledge will help us more realistic prediction of future (low entropy).

Relevant information of any type will reduce entropy and helps us predict more realistic future, that information can be word "meat" is present in sentence or word "meat" is not present. This is called Information Gain

Formally

entropy is lack of order of predicability

Hey how about to copy all fields, change one of them to the same value + something else.

SELECT foo, bar, Event_ID+"155"
  FROM Table
 WHERE Event_ID = "120"

Tags and Elements are not the same.

Elements

They are the pieces themselves, i.e. a paragraph is an element, or a header is an element, even the body is an element. Most elements can contain other elements, as the body element would contain header elements, paragraph elements, in fact pretty much all of the visible elements of the DOM.

Eg:

<p>This is the <span>Home</span> page</p>

Tags

Tags are not the elements themselves, rather they're the bits of text you use to tell the computer where an element begins and ends. When you 'mark up' a document, you generally don't want those extra notes that are not really part of the text to be presented to the reader. HTML borrows a technique from another language, SGML, to provide an easy way for a computer to determine which parts are "MarkUp" and which parts are the content. By using '<' and '>' as a kind of parentheses, HTML can indicate the beginning and end of a tag, i.e. the presence of '<' tells the browser 'this next bit is markup, pay attention'.

The browser sees the letters '

' and decides 'A new paragraph is starting, I'd better start a new line and maybe indent it'. Then when it sees '

Firebase listeners fire for both the initial data and any changes.

If you're looking to synchronize the data in a collection, use ChildEventListener. If you're looking to synchronize a single object, use ValueEventListener. Note that in both cases you're not "getting" the data. You're synchronizing it, which means that the callback may be invoked multiple times: for the initial data and whenever the data gets updated.

This is covered in Firebase's quickstart guide for Android. The relevant code and quote:

FirebaseRef.child("message").addValueEventListener(new ValueEventListener() {
  @Override
  public void onDataChange(DataSnapshot snapshot) {
    System.out.println(snapshot.getValue());  //prints "Do you have data? You'll love Firebase."
  }
  @Override
  public void onCancelled(DatabaseError databaseError) {        
  }
});

In the example above, the value event will fire once for the initial state of the data, and then again every time the value of that data changes.

Please spend a few moments to go through that quick start. It shouldn't take more than 15 minutes and it will save you from a lot of head scratching and questions. The Firebase Android Guide is probably a good next destination, for this question specifically: https://firebase.google.com/docs/database/android/read-and-write

Use ampersand to specify the parent selector.

    &:after {

This XML file does not appear to have any style information associated with it. The document tree is shown below.

You will get this error in the client side when the client (the webbrowser) for some reason interprets the HTTP response content as text/xml instead of text/html and the parsed XML tree doesn't have any XML-stylesheet. In other words, the webbrowser incorrectly parsed the retrieved HTTP response content as XML instead of as HTML due to the wrong or missing HTTP response content type.

In case of JSF/Facelets files which have the default extension of .xhtml, that can in turn happen if the HTTP request hasn't invoked the FacesServlet and thus it wasn't able to parse the Facelets file and generate the desired HTML output based on the XHTML source code. Firefox is then merely guessing the HTTP response content type based on the .xhtml file extension which is in your Firefox configuration apparently by default interpreted as text/xml.

You need to make sure that the HTTP request URL, as you see in browser's address bar, matches the <url-pattern> of the FacesServlet as registered in webapp's web.xml, so that it will be invoked and be able to generate the desired HTML output based on the XHTML source code. If it's for example *.jsf, then you need to open the page by /some.jsf instead of /some.xhtml. Alternatively, you can also just change the <url-pattern> to *.xhtml. This way you never need to fiddle with virtual URLs.

See also:

• JSF Facelets: Sometimes I see the URL is .jsf and sometimes .xhtml. Why?

Note thus that you don't actually need a XML stylesheet. This all was just misinterpretation by the webbrowser while trying to do its best to make something presentable out of the retrieved HTTP response content. It should actually have retrieved the properly generated HTML output, Firefox surely knows precisely how to deal with HTML content.

Try using now.date() to get a Date object rather than a DateTime.

If that doesn't work, then converting that to a string should work:

now = datetime.datetime(2009,5,5)
str_now = now.date().isoformat()
cursor.execute('INSERT INTO table (name, id, datecolumn) VALUES (%s,%s,%s)', ('name',4,str_now))

I'm doing something like that.

Getting the values in lowercase and MySQL does the rest

    $string = $_GET['string'];
    mysqli_query($con,"SELECT *
                       FROM table_name
                       WHERE LOWER(column_name)
                       LIKE LOWER('%$string%')");

And For MySQL PDO Alternative:

        $string = $_GET['string'];
        $q = "SELECT *
              FROM table_name
              WHERE LOWER(column_name)
              LIKE LOWER(?);";
        $query = $dbConnection->prepare($q);
        $query->bindValue(1, "%$string%", PDO::PARAM_STR);
        $query->execute();

Sometimes when the dev process has both WIN work stations and LINUX systems (hosting) and in the code you do not see any output before the related line, it could be the formatting of the file and the lack of Unix LF (linefeed) line ending.

What we usually do in order to quickly fix this, is rename the file and on the LINUX system create a new file instead of the renamed one, and then copy the content into that. Many times this solve the issue as some of the files that were created in WIN once moved to the hosting cause this issue.

This fix is an easy fix for sites we manage by FTP and sometimes can save our new team members some time.

Here's one explanation:

Once a socket is no longer required, the calling program can discard the socket by applying a close subroutine to the socket descriptor. If a reliable delivery socket has data associated with it when a close takes place, the system continues to attempt data transfer. However, if the data is still undelivered, the system discards the data. Should the application program have no use for any pending data, it can use the shutdown subroutine on the socket prior to closing it.

None of the other answers worked for me.

This did: (in Startup.cs)

public class Startup
{
    public void Configuration(IAppBuilder app)
    {
        var config = new HttpConfiguration();

        WebApiConfig.Register(config);

        // Here: 
        config.IncludeErrorDetailPolicy = IncludeErrorDetailPolicy.Always;
    }
}

(or you can put it in WebApiConfig.cs):

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{action}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );

        // Here: 
        config.IncludeErrorDetailPolicy = IncludeErrorDetailPolicy.Always;
    }
}

You may do....in easy way...within one line Logic

#include <stdio.h>

int main()
{
    int a, b;
    printf("Enter A :");
    scanf("%d",&a);
    printf("Enter B :");
    scanf("%d",&b);
    int a = 1,b = 2;
    a=a^b^(b=a);
    printf("\nValue of A=%d B=%d ",a,b);

    return 1;
}

or

#include <stdio.h>

int main()
{
    int a, b;
    printf("Enter A :");
    scanf("%d",&a);
    printf("Enter B :");
    scanf("%d",&b);
    int a = 1,b = 2;
    a=a+b-(b=a);
    printf("\nValue of A=%d B=%d ",a,b);

    return 1;
}

The best way for copying files to the container I found is mounting a directory on host using -v option of docker run command.

I had a similar issue using the JAXB reference implementation and JBoss AS 7.1. I was able to write an integration test that confirmed JAXB worked outside of the JBoss environment (suggesting the problem might be the class loader in JBoss).

This is the code that was giving the error (i.e. not working):

private static final JAXBContext JC;

static {
    try {
        JC = JAXBContext.newInstance("org.foo.bar");
    } catch (Exception exp) {
        throw new RuntimeException(exp);
    }
}

and this is the code that worked (ValueSet is one of the classes marshaled from my XML).

private static final JAXBContext JC;

static {
    try {
        ClassLoader classLoader = ValueSet.class.getClassLoader();
        JC = JAXBContext.newInstance("org.foo.bar", classLoader);
    } catch (Exception exp) {
        throw new RuntimeException(exp);
    }
}

In some cases I got the Class nor any of its super class is known to this context. In other cases I also got an exception of org.foo.bar.ValueSet cannot be cast to org.foo.bar.ValueSet (similar to the issue described here: ClassCastException when casting to the same class).

if, for any reasons, you don't want to add a wrapper (in my first case it was for <tr/> components), you can use a functionnal component.

Instead of having a single components/MyCompo.vue you will have few files in a components/MyCompo folder :

• components/MyCompo/index.js
• components/MyCompo/File.vue
• components/MyCompo/Avatar.vue

With this structure, the way you call your component won't change.

components/MyCompo/index.js file content :

import File from './File';
import Avatar from './Avatar';   

const commonSort=(a,b)=>b-a;

export default {
  functional: true,
  name: 'MyCompo',
  props: [ 'someProp', 'plopProp' ],
  render(createElement, context) {
    return [
        createElement( File, { props: Object.assign({light: true, sort: commonSort},context.props) } ),
        createElement( Avatar, { props: Object.assign({light: false, sort: commonSort},context.props) } )
    ]; 
  }
};

And if you have some function or data used in both templates, passed them as properties and that's it !

I let you imagine building list of components and so much features with this pattern.

I like if ((item.Rate ?? 0) == 0) { }

Update 1:

You could also define an extension method like:

public static bool IsNullOrValue(this double? value, double valueToCheck)
{
    return (value??valueToCheck) == valueToCheck;
}

And use it like this:

if(item.IsNullOrValue(0)){} // but you don't get much from it

The command yum that you launch was executed properly. It returns a non zero status which means that an error occured during the processing of the command. You probably want to add some argument to your yum command to fix that.

Your code could show this error this way:

import subprocess
try:
    subprocess.check_output("dir /f",shell=True,stderr=subprocess.STDOUT)
except subprocess.CalledProcessError as e:
    raise RuntimeError("command '{}' return with error (code {}): {}".format(e.cmd, e.returncode, e.output))

For Python 3, I'm using this function:

def user_prompt(question: str) -> bool:
    """ Prompt the yes/no-*question* to the user. """
    from distutils.util import strtobool

    while True:
        user_input = input(question + " [y/n]: ")
        try:
            return bool(strtobool(user_input))
        except ValueError:
            print("Please use y/n or yes/no.\n")

The strtobool() function converts a string into a bool. If the string cant be parsed it will raise a ValueError.

In Python 3 raw_input() has been renamed to input().

As Geoff said, strtobool actually returns 0 or 1, therefore the result has to be cast to bool.

This is the implementation of strtobool, if you want special words to be recognized as true, you can copy the code and add your own cases.

def strtobool (val):
    """Convert a string representation of truth to true (1) or false (0).
    True values are 'y', 'yes', 't', 'true', 'on', and '1'; false values
    are 'n', 'no', 'f', 'false', 'off', and '0'.  Raises ValueError if
    'val' is anything else.
    """
    val = val.lower()
    if val in ('y', 'yes', 't', 'true', 'on', '1'):
        return 1
    elif val in ('n', 'no', 'f', 'false', 'off', '0'):
        return 0
    else:
        raise ValueError("invalid truth value %r" % (val,))

My test string for the following:

testing='12345,abc,123,54321,ab15234,123456,52341';

If I understand your question, you'd want ["12345", "54321", "15234", "52341"].

If JS engines supported regexp lookbehinds, you could do:

testing.match(/(?<!\d)\d{5}(?!\d)/g)

Since it doesn't currently, you could:

testing.match(/(?:^|\D)(\d{5})(?!\d)/g)

and remove the leading non-digit from appropriate results, or:

pentadigit=/(?:^|\D)(\d{5})(?!\d)/g;
result = [];
while (( match = pentadigit.exec(testing) )) {
    result.push(match[1]);
}

Note that for IE, it seems you need to use a RegExp stored in a variable rather than a literal regexp in the while loop, otherwise you'll get an infinite loop.

For your command you also could refer to the following example:

sudo sh -c 'whoami; whoami'

The "stack" term means stack! That means if you have experience in working with these technologies/framework or not. Since all these come together in a LAMP package, which you can download and install, they call it a stack.

instead.

The .intValue() method is defined in class Number, which Long extends.

This debate boils down to the age-old question of whether the developers know best or whether the user knows best. Professional designers in all areas of human factors struggle with this every day.

Ted has made a point in that one of the most downloaded apps on the Market is the 'App Killer'. People get a bit of extra serotonin when they quit applications. They're used to it with a desktop/laptop. It keeps things moving fast. It keeps the processor cool and the fan from turning on. It uses less power.

When you consider that a mobile device is a much smaller ship, then you can especially appreciate their incentive to 'throw overboard what you no longer need'. Now the developers of Android have reasoned that the OS knows best and that quitting an app is antique. I wholeheartedly support this.

However, I also believe that you should not frustrate the user, even if that frustration is borne out of their own ignorance. Because of that, I conclude that having a 'Quit' option is good design, even if it is mostly a placebo button that does nothing more than close a View.

I had this error when i renamed the pc in the windows-properties. The pc-name must be updated in the listener.ora-file

It's also worth referencing this Bluebird promises library wiki page that shows how to manage the arguments object into array in a way that makes the function optimizable under V8 JavaScript engine:

function doesntLeakArguments() {
    var args = new Array(arguments.length);
    for(var i = 0; i < args.length; ++i) {
        args[i] = arguments[i];
    }
    return args;
}

This method is used in favor of var args = [].slice.call(arguments);. The author also shows how a build step can help reduce the verbosity.

I have a 645GB text file, and none of the earlier exact solutions (e.g. wc -l) returned an answer within 5 minutes.

Instead, here is Python script that computes the approximate number of lines in a huge file. (My text file apparently has about 5.5 billion lines.) The Python script does the following:

A. Counts the number of bytes in the file.

B. Reads the first N lines in the file (as a sample) and computes the average line length.

C. Computes A/B as the approximate number of lines.

It follows along the line of Nico's answer, but instead of taking the length of one line, it computes the average length of the first N lines.

Note: I'm assuming an ASCII text file, so I expect the Python len() function to return the number of chars as the number of bytes.

Put this code into a file line_length.py:

#!/usr/bin/env python

# Usage:
# python line_length.py <filename> <N> 

import os
import sys
import numpy as np

if __name__ == '__main__':

    file_name = sys.argv[1]
    N = int(sys.argv[2]) # Number of first lines to use as sample.
    file_length_in_bytes = os.path.getsize(file_name)
    lengths = [] # Accumulate line lengths.
    num_lines = 0

    with open(file_name) as f:
        for line in f:
            num_lines += 1
            if num_lines > N:
                break
            lengths.append(len(line))

    arr = np.array(lengths)
    lines_count = len(arr)
    line_length_mean = np.mean(arr)
    line_length_std = np.std(arr)

    line_count_mean = file_length_in_bytes / line_length_mean

    print('File has %d bytes.' % (file_length_in_bytes))
    print('%.2f mean bytes per line (%.2f std)' % (line_length_mean, line_length_std))
    print('Approximately %d lines' % (line_count_mean))

Invoke it like this with N=5000.

% python line_length.py big_file.txt 5000

File has 645620992933 bytes.
116.34 mean bytes per line (42.11 std)
Approximately 5549547119 lines

So there are about 5.5 billion lines in the file.

The below answer is good:

grep -r -i --include \*.h --include \*.cpp CP_Image ~/path[12345] | mailx -s GREP [email protected]

But can be updated to:

grep -r -i --include \*.{h,cpp} CP_Image ~/path[12345] | mailx -s GREP [email protected]

Which can be more simple.

Hej man, why are you using this ?

dir /s/b/o:gn > f.txt (wrong one)

Don't you know what is that 'g' in '/o' ??

Check this out: http://www.computerhope.com/dirhlp.htm or dir /? for dir help

You should be using this instead:

dir /s/b/o:n > f.txt (right one)

Because the second element is null after you clear the list.

Use:

String s = myList.get(0);

And remember, index 0 is the first element.

First off, in order to have any image "resize" to fit a picturebox, you can set the PictureBox.SizeMode = PictureBoxSizeMode.StretchImage

If you want to do clipping of the image beforehand (i.e. cut off sides or top and bottom), then you need to clearly define what behavior you want (start at top, fill the height of the pciturebox and crop the rest, or start at the bottom, fill the height of the picturebox to the top, etc), and it should be fairly simple to use the Height / Width properties of both the picturebox and the image to clip the image and get the effect you are looking for.

If someone is using bootstrap sass note the code is on the _reboot.scss file like this:

button:focus {
  outline: 1px dotted;
  outline: 5px auto -webkit-focus-ring-color;
}

So if you want to keep the _reboot file I guess feel free to override with plain css instead of trying to look for a variable to change.

None of the above worked for me because my devices are in a balance-rr bond. Querying either would say the same MAC address with ip l l, ifconfig, or /sys/class/net/${device}/address, so one of them is correct, and one is unknown.

But this works if you haven't renamed the device (any tips on what I missed?):

udevadm info -q all --path "/sys/class/net/${device}"

And this works even if you rename it (eg. ip l set name x0 dev p4p1):

cat /proc/net/bonding/bond0

or my ugly script that makes it more parsable (untested driver/os/whatever compatibility):

awk -F ': ' '
         $0 == "" && interface != "" {
            printf "%s %s %s\n", interface, mac, status;
            interface="";
            mac=""
         }; 
         $1 == "Slave Interface" {
            interface=$2
         }; 
         $1 == "Permanent HW addr" {
            mac=$2
         };
         $1 == "MII Status" {
            status=$2
         };
         END {
            printf "%s %s %s\n", interface, mac, status
         }' /proc/net/bonding/bond0

If it's working in the debug, then wait must be the proper solution.
I will suggest to use the explicit wait, as given below:

WebDriverWait wait = new WebDriverWait(new ChromeDriver(), 5);
wait.until(ExpectedConditions.presenceOfElementLocated(By.cssSelector("#Passwd")));

You get this error message if a Python file was closed from "the outside", i.e. not from the file object's close() method:

>>> f = open(".bashrc")
>>> os.close(f.fileno())
>>> del f
close failed in file object destructor:
IOError: [Errno 9] Bad file descriptor

The line del f deletes the last reference to the file object, causing its destructor file.__del__ to be called. The internal state of the file object indicates the file is still open since f.close() was never called, so the destructor tries to close the file. The OS subsequently throws an error because of the attempt to close a file that's not open.

Since the implementation of os.system() does not create any Python file objects, it does not seem likely that the system() call is the origin of the error. Maybe you could show a bit more code?

Let's me give a more detail example. As to the below struct:

struct Count{
    uint32_t c;

    Count(uint32_t i=0):c(i){}

    uint32_t getCount(){
        return c;
    }

    uint32_t add(const Count& count){
        uint32_t total = c + count.getCount();
        return total;
    }
};

As you see the above, the IDE(CLion), will give tips Non-const function 'getCount' is called on the const object. In the method add count is declared as const object, but the method getCount is not const method, so count.getCount() may change the members in count.

Compile error as below(core message in my compiler):

error: passing 'const xy_stl::Count' as 'this' argument discards qualifiers [-fpermissive]

To solve the above problem, you can:

1. change the method uint32_t getCount(){...} to uint32_t getCount() const {...}. So count.getCount() won't change the members in count.

or

2. change uint32_t add(const Count& count){...} to uint32_t add(Count& count){...}. So count don't care about changing members in it.

As to you problem, objects in the std::set are stored as const StudentT, but the method getId and getName are not const, so you give the above error.

You can also see this question Meaning of 'const' last in a function declaration of a class? for more detail.

1. Only abstract classes can have abstract members.
2. A non-abstract class that inherits from an abstract class must override its abstract members.
3. An abstract member is implicitly virtual.
4. An abstract member cannot provide any implementation (abstract is called pure virtual in some languages).

This is what DocumentFragment was meant for.

var frag = document.createDocumentFragment();
var span = document.createElement("span");
span.innerHTML = htmldata;
for (var i = 0, ii = span.childNodes.length; i < ii; i++) {
    frag.appendChild(span.childNodes[i]);
}
element.appendChild(frag);

document.createDocumentFragment, .childNodes

The reason to prefer Promises over callback functions is to have multiple callbacks and to avoid the problems like Callback Hell.

Callback hell (for more details, refer http://callbackhell.com/): Asynchronous javascript, or javascript that uses callbacks, is hard to get right intuitively. A lot of code ends up looking like this:

asyncCall(function(err, data1){
    if(err) return callback(err);       
    anotherAsyncCall(function(err2, data2){
        if(err2) return calllback(err2);
        oneMoreAsyncCall(function(err3, data3){
            if(err3) return callback(err3);
            // are we done yet?
        });
    });
});

With Promises above code can be rewritten as below:

asyncCall()
.then(function(data1){
    // do something...
    return anotherAsyncCall();
})
.then(function(data2){
    // do something...  
    return oneMoreAsyncCall();    
})
.then(function(data3){
    // the third and final async response
})
.fail(function(err) {
    // handle any error resulting from any of the above calls    
})
.done();

Postgres 9.4 or later

Use WITH ORDINALITY for set-returning functions:

When a function in the FROM clause is suffixed by WITH ORDINALITY, a bigint column is appended to the output which starts from 1 and increments by 1 for each row of the function's output. This is most useful in the case of set returning functions such as unnest().

In combination with the LATERAL feature in pg 9.3+, and according to this thread on pgsql-hackers, the above query can now be written as:

SELECT t.id, a.elem, a.nr
FROM   tbl AS t
LEFT   JOIN LATERAL unnest(string_to_array(t.elements, ','))
                    WITH ORDINALITY AS a(elem, nr) ON TRUE;

LEFT JOIN ... ON TRUE preserves all rows in the left table, even if the table expression to the right returns no rows. If that's of no concern you can use this otherwise equivalent, less verbose form with an implicit CROSS JOIN LATERAL:

SELECT t.id, a.elem, a.nr
FROM   tbl t, unnest(string_to_array(t.elements, ',')) WITH ORDINALITY a(elem, nr);

Or simpler if based off an actual array (arr being an array column):

SELECT t.id, a.elem, a.nr
FROM   tbl t, unnest(t.arr) WITH ORDINALITY a(elem, nr);

Or even, with minimal syntax:

SELECT id, a, ordinality
FROM   tbl, unnest(arr) WITH ORDINALITY a;

a is automatically table and column alias. The default name of the added ordinality column is ordinality. But it's better (safer, cleaner) to add explicit column aliases and table-qualify columns.

Postgres 8.4 - 9.3

With row_number() OVER (PARTITION BY id ORDER BY elem) you get numbers according to the sort order, not the ordinal number of the original ordinal position in the string.

You can simply omit ORDER BY:

SELECT *, row_number() OVER (PARTITION by id) AS nr
FROM  (SELECT id, regexp_split_to_table(elements, ',') AS elem FROM tbl) t;

While this normally works and I have never seen it fail in simple queries, PostgreSQL asserts nothing concerning the order of rows without ORDER BY. It happens to work due to an implementation detail.

To guarantee ordinal numbers of elements in the blank-separated string:

SELECT id, arr[nr] AS elem, nr
FROM  (
   SELECT *, generate_subscripts(arr, 1) AS nr
   FROM  (SELECT id, string_to_array(elements, ' ') AS arr FROM tbl) t
   ) sub;

Or simpler if based off an actual array:

SELECT id, arr[nr] AS elem, nr
FROM  (SELECT *, generate_subscripts(arr, 1) AS nr FROM tbl) t;

Related answer on dba.SE:

• How to preserve the original order of elements in an unnested array?

Postgres 8.1 - 8.4

None of these features are available, yet: RETURNS TABLE, generate_subscripts(), unnest(), array_length(). But this works:

CREATE FUNCTION f_unnest_ord(anyarray, OUT val anyelement, OUT ordinality integer)
  RETURNS SETOF record
  LANGUAGE sql IMMUTABLE AS
'SELECT $1[i], i - array_lower($1,1) + 1
 FROM   generate_series(array_lower($1,1), array_upper($1,1)) i';

Note in particular, that the array index can differ from ordinal positions of elements. Consider this demo with an extended function:

CREATE FUNCTION f_unnest_ord_idx(anyarray, OUT val anyelement, OUT ordinality int, OUT idx int)
  RETURNS SETOF record
  LANGUAGE sql IMMUTABLE AS
'SELECT $1[i], i - array_lower($1,1) + 1, i
 FROM   generate_series(array_lower($1,1), array_upper($1,1)) i';

SELECT id, arr, (rec).*
FROM  (
   SELECT *, f_unnest_ord_idx(arr) AS rec
   FROM  (VALUES (1, '{a,b,c}'::text[])  --  short for: '[1:3]={a,b,c}'
               , (2, '[5:7]={a,b,c}')
               , (3, '[-9:-7]={a,b,c}')
      ) t(id, arr)
   ) sub;

 id |       arr       | val | ordinality | idx
----+-----------------+-----+------------+-----
  1 | {a,b,c}         | a   |          1 |   1
  1 | {a,b,c}         | b   |          2 |   2
  1 | {a,b,c}         | c   |          3 |   3
  2 | [5:7]={a,b,c}   | a   |          1 |   5
  2 | [5:7]={a,b,c}   | b   |          2 |   6
  2 | [5:7]={a,b,c}   | c   |          3 |   7
  3 | [-9:-7]={a,b,c} | a   |          1 |  -9
  3 | [-9:-7]={a,b,c} | b   |          2 |  -8
  3 | [-9:-7]={a,b,c} | c   |          3 |  -7

Yes you can, just pass the integer param to the split method

String stSplit = "apple=fruit table price=5"

stSplit.split("=", 2);

Here is a java doc reference : String#split(java.lang.String, int)

Though the answer has been given for the question. I would like to add, if in case we need to print numbers without any spaces then we can use the following code

        for i in range(1,n):
            print(i,end="")

You can set CSS using three different ways as mentioned below :-

1.External style sheet
2.Internal style sheet
3.Inline style

Preferred / ideal way of setting the css style is using as external style sheets when the style is applied to many pages. With an external style sheet, you can change the look of an entire Web site by changing one file.

sample usage can be :-

<head>
    <link rel="stylesheet" type="text/css" href="your_css_file_name.css">
</head>

If you want to apply a unique style to a single document then you can use Internal style sheet.

Don't use inline style sheet,as it mixes content with presentation and looses many advantages.

1.84E-07 is the exact value, represented using scientific notation, also known as exponential notation.

1.845E-07 is the same as 0.0000001845. Excel will display a number very close to 0 as 0, unless you modify the formatting of the cell to display more decimals.

C# however will get the actual value from the cell. The ToString method use the e-notation when converting small numbers to a string.

You can specify a format string if you don't want to use the e-notation.

UPDATE: From the comments this answer seems to be out of date

The Flutter documentation points out where you can change the display name of your application for both Android and iOS. This may be what you are looking for:

• Preparing an Android App for Release
• Preparing an iOS App for Release

For Android

It seems you have already found this in the AndroidManifest.xml as the application entry.

Review the default App Manifest file AndroidManifest.xml located in /android/app/src/main/ and verify the values are correct, especially:

application: Edit the application tag to reflect the final name of the app.

For iOS

See the Review Xcode project settings section:

Navigate to your target’s settings in Xcode:

In Xcode, open Runner.xcworkspace in your app’s ios folder.

To view your app’s settings, select the Runner project in the Xcode project navigator. Then, in the main view sidebar, select the Runner target.

Select the General tab. Next, you’ll verify the most important settings:

Display Name: the name of the app to be displayed on the home screen and elsewhere.

In the Google Maps API v2 Demo there is a MarkerDemoActivity class in which you can see how a custom Image is set to a GoogleMap.

// Uses a custom icon.
mSydney = mMap.addMarker(new MarkerOptions()
    .position(SYDNEY)
    .title("Sydney")
    .snippet("Population: 4,627,300")
    .icon(BitmapDescriptorFactory.fromResource(R.drawable.arrow)));

As this just replaces the marker with an image you might want to use a Canvas to draw more complex and fancier stuff:

Bitmap.Config conf = Bitmap.Config.ARGB_8888;
Bitmap bmp = Bitmap.createBitmap(80, 80, conf);
Canvas canvas1 = new Canvas(bmp);

// paint defines the text color, stroke width and size
Paint color = new Paint();
color.setTextSize(35);
color.setColor(Color.BLACK);

// modify canvas
canvas1.drawBitmap(BitmapFactory.decodeResource(getResources(),
    R.drawable.user_picture_image), 0,0, color);
canvas1.drawText("User Name!", 30, 40, color);

// add marker to Map
mMap.addMarker(new MarkerOptions()
    .position(USER_POSITION)
    .icon(BitmapDescriptorFactory.fromBitmap(bmp))
    // Specifies the anchor to be at a particular point in the marker image.
    .anchor(0.5f, 1));

This draws the Canvas canvas1 onto the GoogleMap mMap. The code should (mostly) speak for itself, there are many tutorials out there how to draw a Canvas. You can start by looking at the Canvas and Drawables from the Android Developer page.

Now you also want to download a picture from an URL.

URL url = new URL(user_image_url);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();   
conn.setDoInput(true);   
conn.connect();     
InputStream is = conn.getInputStream();
bmImg = BitmapFactory.decodeStream(is); 

You must download the image from an background thread (you could use AsyncTask or Volley or RxJava for that).

After that you can replace the BitmapFactory.decodeResource(getResources(), R.drawable.user_picture_image) with your downloaded image bmImg.

a simpler solution based on this answer:

public static String prettyFormat(String input, int indent) {
    try {
        Source xmlInput = new StreamSource(new StringReader(input));
        StringWriter stringWriter = new StringWriter();
        StreamResult xmlOutput = new StreamResult(stringWriter);
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        transformerFactory.setAttribute("indent-number", indent);
        Transformer transformer = transformerFactory.newTransformer(); 
        transformer.setOutputProperty(OutputKeys.INDENT, "yes");
        transformer.transform(xmlInput, xmlOutput);
        return xmlOutput.getWriter().toString();
    } catch (Exception e) {
        throw new RuntimeException(e); // simple exception handling, please review it
    }
}

public static String prettyFormat(String input) {
    return prettyFormat(input, 2);
}

testcase:

prettyFormat("<root><child>aaa</child><child/></root>");

returns:

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <child>aaa</child>
  <child/>
</root>

Hold CTRL and press F6 until you reached the editor you want, then release. The UI is not as pretty as the window selection, but the functionality is the same.

Just iterate over each line in the file. Python automatically checks for the End of file and closes the file for you (using the with syntax).

with open('fileName', 'r') as f:
    for line in f:
       if 'str' in line:
           break

To fix center position, I use:

open : function() {
    var t = $(this).parent(), w = window;
    t.offset({
        top: (w.height() / 2) - (t.height() / 2),
        left: (w.width() / 2) - (t.width() / 2)
    });
}

The conflict message:

CONFLICT (delete/modify): res/layout/dialog_item.xml deleted in dialog and modified in HEAD

means that res/layout/dialog_item.xml was deleted in the 'dialog' branch you are merging, but was modified in HEAD (in the branch you are merging to).

So you have to decide whether

• remove file using "git rm res/layout/dialog_item.xml"

or

• accept version from HEAD (perhaps after editing it) with "git add res/layout/dialog_item.xml"

Then you finalize merge with "git commit".

Note that git will warn you that you are creating a merge commit, in the (rare) case where it is something you don't want. Probably remains from the days where said case was less rare.

$date = DateTime::createFromFormat('m-d-Y', '04-15-2013');
$date->modify('+1 day');
echo $date->format('m-d-Y');

See it in action

Or in PHP 5.4+

echo (DateTime::createFromFormat('m-d-Y', '04-15-2013'))->modify('+1 day')->format('m-d-Y');

reference

• DateTime::createFromFormat()

If you are using the Git Bash shell, you can use the following trick:

> webpage.html

This is actually the same as:

echo "" > webpage.html

Then, you can use git add webpage.html to stage the file.

There are several ways to cause your program to terminate. Which one is appropriate depends on why you want your program to terminate. The vast majority of the time it should be by executing a return statement in your main function. As in the following.

int main()
{
     f();
     return 0;
}

As others have identified this allows all your stack variables to be properly destructed so as to clean up properly. This is very important.

If you have detected an error somewhere deep in your code and you need to exit out you should throw an exception to return to the main function. As in the following.

struct stop_now_t { };
void f()
{
      // ...
      if (some_condition())
           throw stop_now_t();
      // ...
}

int main()
{
     try {
          f();
     } catch (stop_now_t& stop) {
          return 1;
     }
     return 0;
 }

This causes the stack to be unwound an all your stack variables to be destructed. Still very important. Note that it is appropriate to indicate failure with a non-zero return value.

If in the unlikely case that your program detects a condition that indicates it is no longer safe to execute any more statements then you should use std::abort(). This will bring your program to a sudden stop with no further processing. std::exit() is similar but may call atexit handlers which could be bad if your program is sufficiently borked.

You have a company and there is only 1 worker but you got 1 new project at that time you hire new candidate -- this is horizontal scaling. where new candidate is new machines and project is new traffic/calls to your api's.

Where as 1 project with an IIT/NIT guy handling all request to your api/traffic. If any time more request to your api's then fire him and replacing him with a high IQ NIT/IIT guy -- this is vertical scaling.

This thread is old but since no one posted about require.context I'm going to mention it:

You can use require.context to set the folder to look through like this:

var req = require.context('../../mydir/', true)
// true here is for use subdirectories, you can also specify regex as third param

return req('./myfile.js')

Change that import to

from matplotlib.pyplot import *

Note that this style of imports (from X import *) is generally discouraged. I would recommend using the following instead:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4])

In-Short Differences are

1) PCL is not going to have Full Access to .NET Framework , where as SharedProject has.

2) #ifdef for platform specific code - you can not write in PCL (#ifdef option isn’t available to you in a PCL because it’s compiled separately, as its own DLL, so at compile time (when the #ifdef is evaluated) it doesn’t know what platform it will be part of. ) where as Shared project you can.

3) Platform specific code is achieved using Inversion Of Control in PCL , where as using #ifdef statements you can achieve the same in Shared Project.

An excellent article which illustrates differences between PCL vs Shared Project can be found at the following link

http://hotkrossbits.com/2015/05/03/xamarin-forms-pcl-vs-shared-project/

I had to also remove session cookies like this:

session_start(); 
$_SESSION = []; 

// If it's desired to kill the session, also 
// delete the session cookie. 
// Note: This will destroy the session, and 
// not just the session data! 
if (ini_get("session.use_cookies")) { 
    $params = session_get_cookie_params(); 
    setcookie(session_name(), '', time() - 42000, 
        $params["path"], $params["domain"], 
        $params["secure"], $params["httponly"] 
    ); 
} 

// Finally, destroy the session. 
session_destroy();

Either decorate your root entity with the XmlRoot attribute which will be used at compile time.

[XmlRoot(Namespace = "www.contoso.com", ElementName = "MyGroupName", DataType = "string", IsNullable=true)]

Or specify the root attribute when de serializing at runtime.

XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.ElementName = "user";
// xRoot.Namespace = "http://www.cpandl.com";
xRoot.IsNullable = true;

XmlSerializer xs = new XmlSerializer(typeof(User),xRoot);

If you have a worksheet with many rows that all contain the formula, by far the easiest method is to copy a row that is without data (but it does contain formulas), and then "insert copied cells" below/above the row where you want to add. The formulas remain. In a pinch, it is OK to use a row with data. Just clear it or overwrite it after pasting.

Basic and primary difference is, ASP.NET web service is designed to exchange SOAP messages over HTTP only while WCF Service can exchange message using any format (SOAP is default) over any transport protocol i.e. HTTP, TCP, MSMQ or NamedPipes etc.

The bootstrap-live-customizer is a good resource for customising your own bootstrap theme and seeing the results live as you customise. Using this website its very easy to just edit the font and then download the updated .css file.

Other than the given answers, in the case that you have something like this:

<div id="test">
    <input type="file" name="file0" onchange="changed()">
</div>
<script type="text/javascript">
    var isAllowed = true;
    function changed()
    {
        if (isAllowed)
        {
            var tmpHTML = $('#test').html();
            tmpHTML += "<input type=\"file\" name=\"file1\" onchange=\"changed()\">";
            $('#test').html(tmpHTML);
            isAllowed = false;
        }
    }
</script>

meaning that you want to automatically add one more file upload if any files were uploaded, the mentioned code will not work, because after the file is uploaded, the first file-upload element will be recreated and therefore the uploaded file will be wiped from it. You should use .append() instead:

    function changed()
    {
        if (isAllowed)
        {
            var tmpHTML = "<input type=\"file\" name=\"file1\" onchange=\"changed()\">";
            $('#test').append(tmpHTML);
            isAllowed = false;
        }

TAB has a specific meaning in PowerShell. It's for command completion. So if you enter "getch" and then type a TAB. It changes what you typed into "GetChildItem" (it corrects the case, even though that's unnecessary).

From your question, it looks like TAB completion and command completion would overload the TAB key. I'm pretty sure the PowerShell designers didn't want that.

If you convert table field:

1. Define the field so it contains seconds:

    CREATE TABLE IF NOT EXISTS test (
        ...
        field        INTERVAL SECOND(0)
    );
   

2. Extract the value. Remember to cast to int other wise you can get an unpleasant surprise once the intervals are big:

   EXTRACT(EPOCH FROM field)::int

Here's an easier way:

sudo apt-get install maven

More details are here.

I think it should be good if this macro will work in device and simulator, below are the solution.

#define IS_WIDESCREEN (fabs((double)[[UIScreen mainScreen]bounds].size.height - (double)568) < DBL_EPSILON)
#define IS_IPHONE (([[[UIDevice currentDevice] model] isEqualToString:@"iPhone"]) || ([[[UIDevice currentDevice] model] isEqualToString: @"iPhone Simulator"]))
#define IS_IPOD   ([[[UIDevice currentDevice]model] isEqualToString:@"iPod touch"])
#define IS_IPHONE_5 ((IS_IPHONE || IS_IPOD) && IS_WIDESCREEN)

A simple DFS does the work of checking if the given undirected graph has a cycle or not.

Here's the C++ code to the same.

The idea used in the above code is:

If a node which is already discovered/visited is found again and is not the parent node , then we have a cycle.

This can also be explained as below(mentioned by @Rafal Dowgird

If an unexplored edge leads to a node visited before, then the graph contains a cycle.

I just encountered the very same problem with a git repository which always works for me. The problem was that I accessed it through public WiFi access, which redirects to a captive portal upon the first connection (for example to show ads and agree with tos).

Preconditions: adb and wireshark is installed on your computer and you have a rooted android device.

1. Download tcpdump to ~/Downloads
2. adb push ~/Downloads/tcpdump /sdcard/
3. adb shell
4. su root
5. mv /sdcard/tcpdump /data/local/
6. cd /data/local/
7. chmod +x tcpdump
8. ./tcpdump -vv -i any -s 0 -w /sdcard/dump.pcap
9. CTRL+C after you've captured enough packets.
10. exit
11. exit
12. adb pull /sdcard/dump.pcap ~/Downloads/

Now you can open the pcap file using Wireshark.

You can use the easier function preg_match instead, It's better and faster than all of the other ones.

$var = "<tag>Get this var</tag>";
preg_match("/<tag>(.*)<\/tag>/", $var , $new_var);
echo $new_var['1']; 

Output: Get this var

Download Spring STS (SpringSource Tool Suite) and choose Spring Template Project from the Dashboard. This is the easiest way to get a preconfigured spring mvc project, ready to go.

public abstract class SingleFragmentActivity extends Activity {

    public static final String FRAGMENT_TAG = "single";
    private Fragment fragment;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
        if (savedInstanceState == null) {
            fragment = onCreateFragment();
           getFragmentManager().beginTransaction()
                   .add(android.R.id.content, fragment, FRAGMENT_TAG)
                   .commit();
       } else {
           fragment = getFragmentManager().findFragmentByTag(FRAGMENT_TAG);
       }
   }

   public abstract Fragment onCreateFragment();

   public Fragment getFragment() {
       return fragment;
   }

}

use

public class ViewCatalogItemActivity extends SingleFragmentActivity {
    @Override
    public Fragment onCreateFragment() {
        return new FragmentWorkShops();
    }

}

layout.setBackgroundResource(R.drawable.ready); is correct.
Another way to achieve it is to use the following:

final int sdk = android.os.Build.VERSION.SDK_INT;
if(sdk < android.os.Build.VERSION_CODES.JELLY_BEAN) {
    layout.setBackgroundDrawable(ContextCompat.getDrawable(context, R.drawable.ready) );
} else {
    layout.setBackground(ContextCompat.getDrawable(context, R.drawable.ready));
}

But I think the problem occur because you are trying to load big images.
Here is a good tutorial how to load large bitmaps.

UPDATE:
getDrawable(int ) deprecated in API level 22

getDrawable(int ) is now deprecated in API level 22. You should use the following code from the support library instead:

ContextCompat.getDrawable(context, R.drawable.ready)

If you refer to the source code of ContextCompat.getDrawable, it gives you something like this:

/**
 * Return a drawable object associated with a particular resource ID.
 * <p>
 * Starting in {@link android.os.Build.VERSION_CODES#LOLLIPOP}, the returned
 * drawable will be styled for the specified Context's theme.
 *
 * @param id The desired resource identifier, as generated by the aapt tool.
 *            This integer encodes the package, type, and resource entry.
 *            The value 0 is an invalid identifier.
 * @return Drawable An object that can be used to draw this resource.
 */
public static final Drawable getDrawable(Context context, int id) {
    final int version = Build.VERSION.SDK_INT;
    if (version >= 21) {
        return ContextCompatApi21.getDrawable(context, id);
    } else {
        return context.getResources().getDrawable(id);
    }
}

More details on ContextCompat

As of API 22, you should use the getDrawable(int, Theme) method instead of getDrawable(int).

UPDATE:
If you are using the support v4 library, the following will be enough for all versions.

ContextCompat.getDrawable(context, R.drawable.ready)

You will need to add the following in your app build.gradle

compile 'com.android.support:support-v4:23.0.0' # or any version above

Or using ResourceCompat, in any API like below:

import android.support.v4.content.res.ResourcesCompat;
ResourcesCompat.getDrawable(getResources(), R.drawable.name_of_drawable, null);

If anyone else that finds this question and needs a dynamic solution for this where you have an undefined number of columns to transpose to and not exactly 3, you can find a nice solution here: https://github.com/jumpstarter-io/colpivot

Make sure that you have permissions to run the following commands.

If you check the man page of nginx from a terminal

man nginx

you can find this:

-V             Print the nginx version, compiler version, and configure script parameters.

-v             Print the nginx version.

Then type in terminal

nginx -v
nginx version: nginx/1.14.0

nginx -V
nginx version: nginx/1.14.0
built with OpenSSL 1.1.0g  2 Nov 2017
TLS SNI support enabled

If nginx is not installed in your system man nginx command can not find man page, so make sure you have installed nginx.

You can also find the version using this command:

Use one of the command to find the path of nginx

ps aux | grep nginx
ps -ef | grep nginx

root       883  0.0  0.3  44524  3388 ?        Ss   Dec07   0:00 nginx: master process /usr/sbin/nginx -g daemon on; master_process on

Then run from terminal:

/usr/sbin/nginx -v

nginx version: nginx/1.14.0

    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    DocumentBuilder db = dbf.newDocumentBuilder();
    Document dom = db.parse("file.xml");
    Element docEle = dom.getDocumentElement();
    NodeList nl = docEle.getChildNodes();
    int length = nl.getLength();
    for (int i = 0; i < length; i++) {
        if (nl.item(i).getNodeType() == Node.ELEMENT_NODE) {
            Element el = (Element) nl.item(i);
            if (el.getNodeName().contains("staff")) {
                String name = el.getElementsByTagName("name").item(0).getTextContent();
                String phone = el.getElementsByTagName("phone").item(0).getTextContent();
                String email = el.getElementsByTagName("email").item(0).getTextContent();
                String area = el.getElementsByTagName("area").item(0).getTextContent();
                String city = el.getElementsByTagName("city").item(0).getTextContent();
            }
        }
    }

Iterate over all children and nl.item(i).getNodeType() == Node.ELEMENT_NODE is used to filter text nodes out. If there is nothing else in XML what remains are staff nodes.

For each node under stuff (name, phone, email, area, city)

 el.getElementsByTagName("name").item(0).getTextContent(); 

el.getElementsByTagName("name") will extract the "name" nodes under stuff, .item(0) will get you the first node and .getTextContent() will get the text content inside.

Edit: Since we have jackson I would do this in a different way. Define a pojo for the object:

public class Staff {
    private String name;
    private String phone;
    private String email;
    private String area;
    private String city;
...getters setters
}

Then using jackson:

    JsonNode root = new XmlMapper().readTree(xml.getBytes());
    ObjectMapper mapper = new ObjectMapper();
    root.forEach(node -> consume(node, mapper));



private void consume(JsonNode node, ObjectMapper mapper) {
    try {
        Staff staff = mapper.treeToValue(node, Staff.class);
        //TODO your job with staff
    } catch (JsonProcessingException e) {
        e.printStackTrace();
    }
}

You can. Try something like this:

@Path("/todo/{varX}/{varY}")
@Produces({"application/xml", "application/json"})
public Todo whatEverNameYouLike(@PathParam("varX") String varX,
    @PathParam("varY") String varY) {
        Todo todo = new Todo();
        todo.setSummary(varX);
        todo.setDescription(varY);
        return todo;
}

Then call your service with this URL;
http://localhost:8088/JerseyJAXB/rest/todo/summary/description

 if guess == number:
     print ("Good")
 elif guess == 2:
     print ("Bad")
 else:
     print ("Also bad")

Make sure you have your identation right. The syntax is ok.

Use this code to create suitable parameter from your type:

private SqlParameter GenerateTypedParameter(string name, object typedParameter)
{
    DataTable dt = new DataTable();

    var properties = typedParameter.GetType().GetProperties().ToList();
    properties.ForEach(p =>
    {
        dt.Columns.Add(p.Name, Nullable.GetUnderlyingType(p.PropertyType) ?? p.PropertyType);
    });
    var row = dt.NewRow();
    properties.ForEach(p => { row[p.Name] = (p.GetValue(typedParameter) ?? DBNull.Value); });
    dt.Rows.Add(row);

    return new SqlParameter
    {
        Direction = ParameterDirection.Input,
        ParameterName = name,
        Value = dt,
        SqlDbType = SqlDbType.Structured
    };
}

changing the Selenium.WebDriver.ChromeDriver from 2.40.0 to 2.27.0 is ok for me

I had the same issue using IIS.

Make sure the option 'Enable 32bit Applications' is set to true on Advanced Configuration of the Application Pool.

I am using the python package psycopg2 and I got this error while querying. I kept running just the query and then the execute function, but when I reran the connection (shown below), it resolved the issue. So rerun what is above your script i.e the connection, because as someone said above, I think it lost the connection or was out of sync or something.

connection = psycopg2.connect(user = "##",
        password = "##",
        host = "##",
        port = "##",
        database = "##")
cursor = connection.cursor()

CAREFUL: In the command in Lawakush Kurmi's answer (git tag -a v1.0) the -a flag is used. This flag tells Git to create an annotated flag. If you don't provide the flag (i.e. git tag v1.0) then it'll create what's called a lightweight tag.

Annotated tags are recommended, because they include a lot of extra information such as:

• the person who made the tag
• the date the tag was made
• a message for the tag

Because of this, you should always use annotated tags.

In addition to the dropDuplicates option there is the method named as we know it in pandas drop_duplicates:

drop_duplicates() is an alias for dropDuplicates().

Example

s_df = sqlContext.createDataFrame([("foo", 1),
                                   ("foo", 1),
                                   ("bar", 2),
                                   ("foo", 3)], ('k', 'v'))
s_df.show()

+---+---+
|  k|  v|
+---+---+
|foo|  1|
|foo|  1|
|bar|  2|
|foo|  3|
+---+---+

Drop by subset

s_df.drop_duplicates(subset = ['k']).show()

+---+---+
|  k|  v|
+---+---+
|bar|  2|
|foo|  1|
+---+---+
s_df.drop_duplicates().show()


+---+---+
|  k|  v|
+---+---+
|bar|  2|
|foo|  3|
|foo|  1|
+---+---+

The fastest solution would be using the regex prototype function test() and looking for any character that is not a space, tab, or line break \S :

if (!/\S/.test(str)) {
  // Didn't find something other than a space which means it's empty
}

In case you have a super long string, it can make a significant difference as it will stop processing as soon as it finds a non-space character.

the method modify() that you called in the last is called in global context if you want to override modify() you first have to inherit A or B.

Maybe you're trying to do this:

In this case C inherits A

function A() {
    this.modify = function() {
        alert("in A");
    }
}

function B() {
    this.modify = function() {
        alert("in B");
    }
}

C = function() {
    this.modify = function() {
        alert("in C");
    };

    C.prototype.modify(); // you can call this method where you need to call modify of the parent class
}

C.prototype = new A();

Solution 1 is not great. It does work, but adding hacky random or timestamped query strings to the end of your image files will make the browser re-download and cache every version of every image, every time a page is loaded, regardless of weather the image has changed or not on the server.

Solution 2 is useless. Adding nocache headers to an image file is not only very difficult to implement, but it's completely impractical because it requires you to predict when it will be needed in advance, the first time you load any image which you think might change at some point in the future.

Enter Etags...

The absolute best way I've found to solve this is to use ETAGS inside a .htaccess file in your images directory. The following tells Apache to send a unique hash to the browser in the image file headers. This hash only ever changes when time the image file is modified and this change triggers the browser to reload the image the next time it is requested.

<FilesMatch "\.(jpg|jpeg)$">
FileETag MTime Size
</FilesMatch>

if i want to check if any speicfic position of command line arguement is passed or not then how to check? like for example in some scenarios 2 command line args will be passed and in some only one will be passed then how do it check wheather the specfic commnad line is passed or not?

public class check {

public static void main(String[] args) {
if(args[0].length()!=0)
{
System.out.println("entered first if");
}
if(args[0].length()!=0 && args[1].length()!=0)
{
System.out.println("entered second if");
}
}
}

So in the above code if args[1] is not passed then i get java.lang.ArrayIndexOutOfBoundsException:

so how do i tackle this where i can check if second arguement is passed or not and if passed then enter it. need assistance asap.

These are all great suggestions, but if I were you, I would do this in your view model. Within your view model, you can create a relay command that you can then bind to the click event in your item template. To determine if the same item was selected, you can store a reference to your selected item in your view model. I like to use MVVM Light to handle the binding. This makes your project much easier to modify in the future, and allows you to set the binding in Blend.

When all is said and done, your XAML will look like what Sergey suggested. I would avoid using the code behind in your view. I'm going to avoid writing code in this answer, because there is a ton of examples out there.

Here is one: How to use RelayCommand with the MVVM Light framework

If you require an example, please comment, and I will add one.

~Cheers

I said I wasn't going to do an example, but I am. Here you go.

1) In your project, add MVVM Light Libraries Only.

2) Create a class for your view. Generally speaking, you have a view model for each view (view: MainWindow.xaml && viewModel: MainWindowViewModel.cs)

3) Here is the code for the very, very, very basic view model:

All included namespace (if they show up here, I am assuming you already added the reference to them. MVVM Light is in Nuget)

using GalaSoft.MvvmLight;
using GalaSoft.MvvmLight.CommandWpf;
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

Now add a basic public class:

/// <summary>
/// Very basic model for example
/// </summary>
public class BasicModel 
{
    public string Id { get; set; }
    public string Text { get; set; }

    /// <summary>
    /// Constructor
    /// </summary>
    /// <param name="text"></param>
    public BasicModel(string text)
    {
        this.Id = Guid.NewGuid().ToString();
        this.Text = text;
    }
}

Now create your viewmodel:

public class MainWindowViewModel : ViewModelBase
{
    public MainWindowViewModel()
    {
        ModelsCollection = new ObservableCollection<BasicModel>(new List<BasicModel>() {
            new BasicModel("Model one")
            , new BasicModel("Model two")
            , new BasicModel("Model three")
        });
    }

    private BasicModel _selectedBasicModel;

    /// <summary>
    /// Stores the selected mode.
    /// </summary>
    /// <remarks>This is just an example, may be different.</remarks>
    public BasicModel SelectedBasicModel 
    {
        get { return _selectedBasicModel; }
        set { Set(() => SelectedBasicModel, ref _selectedBasicModel, value); }
    }

    private ObservableCollection<BasicModel> _modelsCollection;

    /// <summary>
    /// List to bind to
    /// </summary>
    public ObservableCollection<BasicModel> ModelsCollection
    {
        get { return _modelsCollection; }
        set { Set(() => ModelsCollection, ref _modelsCollection, value); }
    }        
}

In your viewmodel, add a relaycommand. Please note, I made this async and had it pass a parameter.

    private RelayCommand<string> _selectItemRelayCommand;
    /// <summary>
    /// Relay command associated with the selection of an item in the observablecollection
    /// </summary>
    public RelayCommand<string> SelectItemRelayCommand
    {
        get
        {
            if (_selectItemRelayCommand == null)
            {
                _selectItemRelayCommand = new RelayCommand<string>(async (id) =>
                {
                    await selectItem(id);
                });
            }

            return _selectItemRelayCommand;
        }
        set { _selectItemRelayCommand = value; }
    }

    /// <summary>
    /// I went with async in case you sub is a long task, and you don't want to lock you UI
    /// </summary>
    /// <returns></returns>
    private async Task<int> selectItem(string id)
    {
        this.SelectedBasicModel = ModelsCollection.FirstOrDefault(x => x.Id == id);
        Console.WriteLine(String.Concat("You just clicked:", SelectedBasicModel.Text));
        //Do async work

        return await Task.FromResult(1);
    }

In the code behind for you view, create a property for you viewmodel and set the datacontext for your view to the viewmodel (please note, there are other ways to do this, but I am trying to make this a simple example.)

public partial class MainWindow : Window
{
    public MainWindowViewModel MyViewModel { get; set; }
    public MainWindow()
    {
        InitializeComponent();

        MyViewModel = new MainWindowViewModel();
        this.DataContext = MyViewModel;
    }
}

In your XAML, you need to add some namespaces to the top of your code

<Window x:Class="Basic_Binding.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
    xmlns:Custom="clr-namespace:GalaSoft.MvvmLight;assembly=GalaSoft.MvvmLight"
    Title="MainWindow" Height="350" Width="525">

I added "i" and "Custom."

Here is the ListView:

<ListView 
        Grid.Row="0" 
        Grid.Column="0" 
        HorizontalContentAlignment="Stretch"
        ItemsSource="{Binding ModelsCollection}"
        ItemTemplate="{DynamicResource BasicModelDataTemplate}">
    </ListView>

Here is the ItemTemplate for the ListView:

<DataTemplate x:Key="BasicModelDataTemplate">
        <Grid>
            <TextBlock Text="{Binding Text}">
                <i:Interaction.Triggers>
                    <i:EventTrigger EventName="MouseLeftButtonUp">
                        <i:InvokeCommandAction 
                            Command="{Binding DataContext.SelectItemRelayCommand, 
                                RelativeSource={RelativeSource FindAncestor, 
                                        AncestorType={x:Type ItemsControl}}}"
                            CommandParameter="{Binding Id}">                                
                        </i:InvokeCommandAction>
                    </i:EventTrigger>
                </i:Interaction.Triggers>
            </TextBlock>
        </Grid>
    </DataTemplate>

Run your application, and check out the output window. You can use a converter to handle the styling of the selected item.

This may seem really complicated, but it makes life a lot easier down the road when you need to separate your view from your ViewModel (e.g. develop a ViewModel for multiple platforms.) Additionally, it makes working in Blend 10x easier. Once you develop your ViewModel, you can hand it over to a designer who can make it look very artsy :). MVVM Light adds some functionality to make Blend recognize your ViewModel. For the most part, you can do just about everything you want to in the ViewModel to affect the view.

If anyone reads this, I hope you find this helpful. If you have questions, please let me know. I used MVVM Light in this example, but you could do this without MVVM Light.

Using JSTL:

<c:set var="message" value='${requestScope["Error_Message"]}' />

Here var sets the variable name and request.getAttribute is equal to requestScope. But it's not essential. ${Error_Message} will give you the same outcome. It'll search every scope. If you want to do some operation with content you take from Error_Message you have to do it using message. like below one.

<c:out value="${message}"/>

(2>/dev/null crontab -l ; echo "0 3 * * * /usr/local/bin/certbot-auto renew") | crontab -

cat <(crontab -l 2>/dev/null) <(echo "0 3 * * * /usr/local/bin/certbot-auto renew") | crontab -

#write out current crontab

crontab -l > mycron 2>/dev/null

#echo new cron into cron file

echo "0 3 * * * /usr/local/bin/certbot-auto renew" >> mycron

#install new cron file

crontab mycron

rm mycron

Because your update uses PUT method, {entryId: $scope.entryId} is considered as data, to tell angular generate from the PUT data, you need to add params: {entryId: '@entryId'} when you define your update, which means

return $resource('http://localhost\\:3000/realmen/:entryId', {}, {
  query: {method:'GET', params:{entryId:''}, isArray:true},
  post: {method:'POST'},
  update: {method:'PUT', params: {entryId: '@entryId'}},
  remove: {method:'DELETE'}
});

Fix: Was missing a closing curly brace on the update line.

Use the SQLite keyword default

db.execSQL("CREATE TABLE " + DATABASE_TABLE + " (" 
    + KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
    + KEY_NAME + " TEXT NOT NULL, "
    + KEY_WORKED + " INTEGER, "
    + KEY_NOTE + " INTEGER DEFAULT 0);");

This link is useful: http://www.sqlite.org/lang_createtable.html

i think this is a best mode to cast to int

   public int ByteToint(Byte B){
        String comb;
        int out=0;
        comb=B+"";
        salida= Integer.parseInt(comb);
        out=out+128;
        return out;
    }

first comvert byte to String

comb=B+"";

next step is comvert to a int

out= Integer.parseInt(comb);

but byte is in rage of -128 to 127 for this reasone, i think is better use rage 0 to 255 and you only need to do this:

out=out+256;

If you want to only download dependencies without doing anything else, then it's:

mvn dependency:resolve

Or to download a single dependency:

mvn dependency:get -Dartifact=groupId:artifactId:version

If you need to download from a specific repository, you can specify that with -DrepoUrl=...
