There is a limit on the number of half-open connections, but afaik not for active connections. Although it appears to depend on the type of Windows 2008 server, at least according to this MSFT employee:

It depends on the edition, Web and Foundation editions have connection limits while Standard, Enterprise, and Datacenter do not.

Maybe useful (Powershell)

http://sbrennan.net/2012/10/21/configuring-application-crash-dumps-with-powershell/

From Windows Vista and Windows Server 2008 onwards Microsoft introduced Windows Error Reporting or WER . This allows the server to be configured to automatically enable the generation and capture of Application Crash dumps. The configuration of this is discussed here . The main problem with the default configuration is the dump files are created and stored in the %APPDATA%\crashdumps folder running the process which can make it awkward to collect dumps as they are spread all over the server. There are additional problems with this as but the main problem I always had with it was that its a simple task that is very repetitive but easy to do incorrectly.

Source code in Powershell (should be useful source code in C# too):

$verifydumpkey = Test-Path "HKLM:\Software\Microsoft\windows\Windows Error Reporting\LocalDumps"
 
    if ($verifydumpkey -eq $false )
    {
    New-Item -Path "HKLM:\Software\Microsoft\windows\Windows Error Reporting\" -Name LocalDumps
    }
 
##### adding the values
 
$dumpkey = "HKLM:\Software\Microsoft\Windows\Windows Error Reporting\LocalDumps"
 
New-ItemProperty $dumpkey -Name "DumpFolder" -Value $Folder -PropertyType "ExpandString" -Force
New-ItemProperty $dumpkey -Name "DumpCount" -Value 10 -PropertyType "Dword" -Force
New-ItemProperty $dumpkey -Name "DumpType" -Value 2 -PropertyType "Dword" -Force

WER -Windows Error Reporting- Folders:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps

%localappdata%\Microsoft\Windows\WER

%LOCALAPPDATA%\CrashDumps

C:\Users[Current User when app> crashed]\AppData\Local\Microsoft\Windows\WER\ReportArchive

I found the solution here:

How to properly -filter multiple strings in a PowerShell copy script

You have to use -Include flag for Get-ChildItem

My Example:

$Location = "C:\user\files" 
$result = (Get-ChildItem $Location\* -Include *.png, *.gif, *.jpg)

Dont forget put "*" after path location.

In my build.gradle I have the following task, which uses the usual linux proxy settings, HTTP_PROXY and HTTPS_PROXY, from the shell env:

task setHttpProxyFromEnv {
    def map = ['HTTP_PROXY': 'http', 'HTTPS_PROXY': 'https']
    for (e in System.getenv()) {
        def key = e.key.toUpperCase()
        if (key in map) {
            def base = map[key]
            def url = e.value.toURL()
            println " - systemProp.${base}.proxy=${url.host}:${url.port}"
            System.setProperty("${base}.proxyHost", url.host.toString())
            System.setProperty("${base}.proxyPort", url.port.toString())
        }
    }
}

build.dependsOn setHttpProxyFromEnv

The quick answer is User = System.Web.HttpContext.Current.User

Ensure your web.config has the following authentication element.

<configuration>
    <system.web>
        <authentication mode="Windows" />
        <authorization>
            <deny users="?"/>
        </authorization>
    </system.web>
</configuration>

I had this problem too. I was trying to run an old 32-bit dll in a 64 bit system. I got it working by copying the .dll to the C:\Windows\SysWoW64\ directory and running this:

%systemroot%\SysWoW64\regsvr32 "C:\Windows\SysWoW64\thenameofyourdll.dll"

And also enabling IIS to run 32 bit apps

Setting environment variable TZ should also works

ex: export TZ=Asia/Shanghai

OK I found it. Arg, an exercise in frustration. They left the old window menu traversal path for changing environment variables in there, but limited access to administrators only. As a normal user, if you want to change it, you need to go through a different set of options to arrive at the same frigging window.

Control Panel -> User Accounts -> User Accounts -> Change my environment variables.

I was debugging the problem for the better part of the day and when I was close to burning the building I discovered the Process Monitor tool from Sysinternals.

Set it to monitor w3wp.exe and check last events before it exits after you fire a request in the browser. Hope that helps further readers.

In my case the problem was coming through the application pool. Try to change your application pool ASP.NET v4.0.

Running IIS 7.5, I had luck adding permissions for the local computer user IUSR. The app pool user didn't work.

The adjustment in the Task Scheduler app actually just controls the enabled state of a certain event log, so you can equivalently adjust the Task Scheduler "history" mode via the Windows command line:

wevtutil set-log Microsoft-Windows-TaskScheduler/Operational /enabled:true

To check the current state:

wevtutil get-log Microsoft-Windows-TaskScheduler/Operational

For the keystroke-averse, here are the slightly abbreviated versions of the above:

wevtutil sl Microsoft-Windows-TaskScheduler/Operational /e:true
wevtutil gl Microsoft-Windows-TaskScheduler/Operational

I just had the same issue and could only install tomcat7 as a serivce using the "32-bit/64-bit Windows Service Installer" version of tomcat:

You are most likely looking for the IIS_IUSRS account.

Unfortunately there's no min (or max)-background-size in CSS you can only use background-size. However if you are seeking a responsive background image you can use Vmin and Vmaxunits for the background-size property to achieve something similar.

example:

#one {
    background:url('../img/blahblah.jpg') no-repeat;
    background-size:10vmin 100%;
}

that will set the height to 10% of the whichever smaller viewport you have whether vertical or horizontal, and will set the width to 100%.

Read more about css units here: https://www.w3schools.com/cssref/css_units.asp

With an HTML form like:

<input type="submit" name="btnSubmit" value="Save Changes" />
<input type="submit" name="btnDelete" value="Delete" />

The PHP code to use would look like:

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // Something posted

    if (isset($_POST['btnDelete'])) {
        // btnDelete
    } else {
        // Assume btnSubmit
    }
}

You should always assume or default to the first submit button to appear in the form HTML source code. In practice, the various browsers reliably send the name/value of a submit button with the post data when:

1. The user literally clicks the submit button with the mouse or pointing device
2. Or there is focus on the submit button (they tabbed to it), and then the Enter key is pressed.

Other ways to submit a form exist, and some browsers/versions decide not to send the name/value of any submit buttons in some of these situations. For example, many users submit forms by pressing the Enter key when the cursor/focus is on a text field. Forms can also be submitted via JavaScript, as well as some more obscure methods.

It's important to pay attention to this detail, otherwise you can really frustrate your users when they submit a form, yet "nothing happens" and their data is lost, because your code failed to detect a form submission, because you did not anticipate the fact that the name/value of a submit button may not be sent with the post data.

Also, the above advice should be used for forms with a single submit button too because you should always assume a default submit button.

I'm aware that the Internet is filled with tons of form-handler tutorials, and almost of all them do nothing more than check for the name and value of a submit button. But, they're just plain wrong!

First of all you missed ScriptService attribute to add in webservice.

[ScriptService]

After then try following method to call webservice via JSON.

        var webAddr = "http://Domain/VBRService.asmx/callJson";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        httpWebRequest.ContentType = "application/json; charset=utf-8";
        httpWebRequest.Method = "POST";            

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = "{\"x\":\"true\"}";

            streamWriter.Write(json);
            streamWriter.Flush();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            return result;
        }

To print the address of a variable, you need to use the %p format. %d is for signed integers. For example:

#include<stdio.h>

void main(void)
{
  int a;

  printf("Address is %p:",&a);
}

        try
        {
           // your code
        }
        catch (Exception w)
        {
            MessageDialog msgDialog = new MessageDialog(w.ToString());
        }

    //this method skips unnecessary trial divisions and makes 
    //trial division more feasible for finding large primes

    public static void main(String[] args) 
    {
        long n= 1000000000039L; //this is a large prime number 
        long i = 2L;
        int test = 0;

        while (n > 1)
        {
            while (n % i == 0)
            {
                n /= i;     
            }

            i++;

            if(i*i > n && n > 1) 
            {
                System.out.println(n); //prints n if it's prime
                test = 1;
                break;
            }
        }

        if (test == 0)  
            System.out.println(i-1); //prints n if it's the largest prime factor
    }

Brother you don't need to set class path just follow these simple steps (I use Apache NetBeans)

Steps:

1. extract the jar file which you want to add in your project.

2. only copy those packages (folder) which you need in the project. (do not copy manifest file)

3. open the main project jar file(dist/file.jar) with WinRAR.

4. paste that folder or package in the main project jar file.

5. Those packages work 100% in your project.

warning: Do not make any changes in the manifest file.

Another method:

• In my case lib folder present outside the dist(main jar file) folder.

• we need to move lib folder in dist folder.then we set class path from manifest.mf file of main jar file.

  Edit the manifest.mf And ADD this type of line

• Class-Path: lib\foldername\jarfilename.jar lib\foldername\jarfilename.jar

Warning: lib folder must be inside the dist folder otherwise jar file do not access your lib folder jar files

XPath has a contains-token function, specifically designed for this situation:

//div[contains-token(@class, 'Test')]

It's only supported in the latest version of XPath (3.1) so you'll need an up-to-date implementation.

select 'abcd' + ltrim(str(1)) + ltrim(str(2))

Spring has org.springframework.core.io.Resource which is designed for such situations. From context.xml you can pass classpath to the bean

<bean class="test.Test1">
        <property name="path" value="classpath:/test/test1.xml" />
    </bean>

and you get it in your bean as Resource:

public void setPath(Resource path) throws IOException {
    File file = path.getFile();
    System.out.println(file);
    }

output

D:\workspace1\spring\target\test-classes\test\test1.xml

Now you can use it in new FileReader(file)

If it's a server socket, you should call listen() on your socket, and then getsockname() to find the port number on which it is listening:

struct sockaddr_in sin;
socklen_t len = sizeof(sin);
if (getsockname(sock, (struct sockaddr *)&sin, &len) == -1)
    perror("getsockname");
else
    printf("port number %d\n", ntohs(sin.sin_port));

As for the IP address, if you use INADDR_ANY then the server socket can accept connections to any of the machine's IP addresses and the server socket itself does not have a specific IP address. For example if your machine has two IP addresses then you might get two incoming connections on this server socket, each with a different local IP address. You can use getsockname() on the socket for a specific connection (which you get from accept()) in order to find out which local IP address is being used on that connection.

Have you tried this?

>>> l=[('A',1), ('B',2), ('C',3)]
>>> d=dict(l)
>>> d
{'A': 1, 'C': 3, 'B': 2}

I have explained use of various CURL options required for CURL PROXY.

$url = 'http://dynupdate.no-ip.com/ip.php';
$proxy = '127.0.0.1:8888';
$proxyauth = 'user:password';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);         // URL for CURL call
curl_setopt($ch, CURLOPT_PROXY, $proxy);     // PROXY details with port
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth);   // Use if proxy have username and password
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5); // If expected to call with specific PROXY type
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);  // If url has redirects then go to the final redirected URL.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);  // Do not outputting it out directly on screen.
curl_setopt($ch, CURLOPT_HEADER, 1);   // If you want Header information of response else make 0
$curl_scraped_page = curl_exec($ch);
curl_close($ch);

echo $curl_scraped_page;

Elasticsearch 1.1+ has the Cardinality Aggregation which will give you a unique count

Note that it is actually an approximation and accuracy may diminish with high-cardinality datasets, but it's generally pretty accurate in my testing.

You can also tune the accuracy with the precision_threshold parameter. The trade-off, or course, is memory usage.

This graph from the docs shows how a higher precision_threshold leads to much more accurate results.

Create a DataView. You cannot sort a DataTable directly, but you can create a DataView from the DataTable and sort that.

Creating: http://msdn.microsoft.com/en-us/library/hy5b8exc.aspx

Sorting: http://msdn.microsoft.com/en-us/library/13wb36xf.aspx

The following code example creates a view that shows all the products where the number of units in stock is less than or equal to the reorder level, sorted first by supplier ID and then by product name.

DataView prodView = new DataView(prodDS.Tables["Products"], "UnitsInStock <= ReorderLevel", "SupplierID, ProductName", DataViewRowState.CurrentRows);

Throughout my researches, I've found 2 viable solutions.

1. If you're using any type of connections, ssh, samba, mounting, disconnect/unmount and reconnect/remount. Try again, this often resolved the problem for me. After that you can do svn cleanup or just keep on working normally (depending on when the problem appeared). Rebooting my computer also fixed the problem once... yes it's dumb I know!

2. Some times all there is to do is to rm -rf your files (or if you're not familiar with the term, just delete your svn folder), and recheckout your svn repository once again. Please note that this does not always solve the problem and you might also have changes you don't want to lose. Which is why I use it as the second option.

Hope this helps you guys!

Click is an event. In your code behind, you need to have a corresponding event handler to whatever you have in the XAML. In this case, you would need to have the following:

private void Command(object sender, RoutedEventArgs e)
{

}

Commands are different. If you need to wire up a command, you'd use the Commmand property of the button and you would either use some pre-built Commands or wire up your own via the CommandManager class (I think).

Got a solution to above problem in a different way where in although i would read entire csv file, but would tweek the display part to show only the content which is desired.

import pandas as pd

df = pd.read_csv('data.csv', skipinitialspace=True)
print df[['star_name', 'ra']]

This one could help in some of the scenario's in learning basics and filtering data on the basis of columns in dataframe.

HTML

<Select id="SDistrict" class="form-control">
    <option value="1" data-color="yellow" > Mango </option>
</select>

JS when initialized

   $('#SDistrict').selectize({
        create: false,
        sortField: 'text',
        onInitialize: function() {
            var s = this;
            this.revertSettings.$children.each(function() {
                $.extend(s.options[this.value], $(this).data());
            });
        },
        onChange: function(value) {
            var option = this.options[value];
            alert(option.text + ' color is ' + option.color);
        }
    });

You can access data attribute of option tag with option.[data-attribute]

This is to synchronize IOs from C and C++ world. If you synchronize, then you have a guaranty that the orders of all IOs is exactly what you expect. In general, the problem is the buffering of IOs that causes the problem, synchronizing let both worlds to share the same buffers. For example cout << "Hello"; printf("World"); cout << "Ciao";; without synchronization you'll never know if you'll get HelloCiaoWorld or HelloWorldCiao or WorldHelloCiao...

tie lets you have the guaranty that IOs channels in C++ world are tied one to each other, which means for example that every output have been flushed before inputs occurs (think about cout << "What's your name ?"; cin >> name;).

You can always mix C or C++ IOs, but if you want some reasonable behavior you must synchronize both worlds. Beware that in general it is not recommended to mix them, if you program in C use C stdio, and if you program in C++ use streams. But you may want to mix existing C libraries into C++ code, and in such a case it is needed to synchronize both.

I had the same problem & in my case this is what I did

@Html.Partial("~/Views/Cabinets/_List.cshtml", (List<Shop>)ViewBag.cabinets)

and in Partial view

@foreach (Shop cabinet in Model)
{
    //...
}

Merely for the purposes of making your program work, take the contents of your main() method and put them in a constructor:

public BookStoreApp2()
{
   // Put contents of main method here
}

Then, in your main() method. Do this:

public void main( String[] args )
{
  new BookStoreApp2();
}

You should use datetime.datetime.strptime:

import datetime

dt = datetime.datetime.strptime(string_date, fmt)

fmt will need to be the appropriate format for your string. You'll find the reference on how to build your format here.

You might want to consider using a div element pop-up window that contains an iframe.

jQuery Dialog is a simple way to get started. Just add an iframe as the content.

Do you mean byte size or string length?

Byte size is measured with strlen(), whereas string length is queried using mb_strlen(). You can use substr() to trim a string to X bytes (note that this will break the string if it has a multi-byte encoding - as pointed out by Darhazer in the comments) and mb_substr() to trim it to X characters in the encoding of the string.

No, this is not supported in MySQL stored routine syntax.

Feel free to submit a feature request at bugs.mysql.com.

Just in case you have pre-stored the values in an array, you can call them in the following format:

for i in range(0,n):
       print arr[i],

Please walk me through the commands I should run to figure this out.

The simplest test you can do is to perform 1000 requests, 10 at a time (which approximately simulates 10 concurrent users getting 100 pages each - over the length of the test).

ab -n 1000 -c 10 -k -H "Accept-Encoding: gzip, deflate" http://www.example.com/

-n 1000 is the number of requests to make.

-c 10 tells AB to do 10 requests at a time, instead of 1 request at a time, to better simulate concurrent visitors (vs. sequential visitors).

-k sends the KeepAlive header, which asks the web server to not shut down the connection after each request is done, but to instead keep reusing it.

I'm also sending the extra header Accept-Encoding: gzip, deflate because mod_deflate is almost always used to compress the text/html output 25%-75% - the effects of which should not be dismissed due to it's impact on the overall performance of the web server (i.e., can transfer 2x the data in the same amount of time, etc).

Multiply that by 60, and you have your requests per minute.

To get real world results, you'll want to test Wordpress instead of some static HTML or index.php file because you need to know how everything performs together: including complex PHP code, and multiple MySQL queries...

For example here is the results of testing a fresh install of Wordpress on the same system and WAMP environment (I'm using WampDeveloper, but there are also Xampp, WampServer, and others)...

Requests per second:    18.68 [#/sec] (mean)

That's 37x slower now!

After the load test, there are a number of things you can do to improve the overall performance (Requests Per Second), and also make the web server more stable under greater load (e.g., increasing the -n and the -c tends to crash Apache), that you can read about here:

The example in your question is that of a curried function which makes use of arrow function and has an implicit return for the first argument.

Arrow function lexically bind this i.e they do not have their own this argument but take the this value from the enclosing scope

An equivalent of the above code would be

const handleChange = (field) {
  return function(e) {
     e.preventDefault();
     /// Do something here
  }.bind(this);
}.bind(this);

One more thing to note about your example is that define handleChange as a const or a function. Probably you are using it as part of a class method and it uses a class fields syntax

so instead of binding the outer function directly, you would bind it in the class constructor

class Something{
    constructor(props) {
       super(props);
       this.handleChange = this.handleChange.bind(this);
    }
    handleChange(field) {
        return function(e) {
           e.preventDefault();
           // do something
        }
    }
}

Another thing to note in the example is the difference between implicit and explicit return.

const abc = (field) => field * 2;

Above is an example of implicit return ie. it takes the value field as argument and returns the result field*2 which explicitly specifying the function to return

For an explicit return you would explicitly tell the method to return the value

const abc = () => { return field*2; }

Another thing to note about arrow functions is that they do not have their own arguments but inherit that from the parents scope as well.

For example if you just define an arrow function like

const handleChange = () => {
   console.log(arguments) // would give an error on running since arguments in undefined
}

As an alternative arrow functions provide the rest parameters that you can use

const handleChange = (...args) => {
   console.log(args);
}

Here it fails at Array.apply(null, new Array(1000000)) and not the .map call.

All functions arguments must fit on callstack(at least pointers of each argument), so in this they are too many arguments for the callstack.

You need to the understand what is call stack.

Stack is a LIFO data structure, which is like an array that only supports push and pop methods.

Let me explain how it works by a simple example:

function a(var1, var2) {
    var3 = 3;
    b(5, 6);
    c(var1, var2);
}
function b(var5, var6) {
    c(7, 8);
}
function c(var7, var8) {
}

When here function a is called, it will call b and c. When b and c are called, the local variables of a are not accessible there because of scoping roles of Javascript, but the Javascript engine must remember the local variables and arguments, so it will push them into the callstack. Let's say you are implementing a JavaScript engine with the Javascript language like Narcissus.

We implement the callStack as array:

var callStack = [];

Everytime a function called we push the local variables into the stack:

callStack.push(currentLocalVaraibles);

Once the function call is finished(like in a, we have called b, b is finished executing and we must return to a), we get back the local variables by poping the stack:

currentLocalVaraibles = callStack.pop();

So when in a we want to call c again, push the local variables in the stack. Now as you know, compilers to be efficient define some limits. Here when you are doing Array.apply(null, new Array(1000000)), your currentLocalVariables object will be huge because it will have 1000000 variables inside. Since .apply will pass each of the given array element as an argument to the function. Once pushed to the call stack this will exceed the memory limit of call stack and it will throw that error.

Same error happens on infinite recursion(function a() { a() }) as too many times, stuff has been pushed to the call stack.

Note that I'm not a compiler engineer and this is just a simplified representation of what's going on. It really is more complex than this. Generally what is pushed to callstack is called stack frame which contains the arguments, local variables and the function address.

Lodash has a simple Dictionary implementation and has good TypeScript support

Install Lodash:

npm install lodash @types/lodash --save

Import and usage:

import { Dictionary } from "lodash";
let properties : Dictionary<string> = {
    "key": "value"        
}
console.log(properties["key"])

I made this simple function to achieve this:

void clearscreen() { 
    for(int i=0; i<10; i++) {
        Serial.println("\n\n\n\n\n\n\n\n\n\n\n\n\n\n");
    }
}

It works well for me in the default terminal

Use Attribute Equals Selector

$('.slide-link[data-slide="0"]').addClass('active');

Fiddle Demo

.find()

it works down the tree

Get the descendants of each element in the current set of matched elements, filtered by a selector, jQuery object, or element.

If you just want the list, then you should ask here: http://unix.stackexchange.com

The answer is: cd / && find -name *.js

If you want to implement this, you have to specify the language.

The easy way is to change the extension to .command or no extension.

But that will open the Terminal, and you will have to close it. If you don't want to see any output, you can use Automator to create a Mac Application that you can double click, add to the dock, etc.

1. Open Automator application
2. Choose "Application" type
3. Type "run" in the Actions search box
4. Double click "Run Shell Script"
5. Click the Run button in upper right corner to test it.
6. File > Save to create the Application.

My solution (ES6 syntax):

const source = "8d7f66a9273fc766cd66d1d";
const target = [];
for (
    const array = Array.from(source);
    array.length;
    target.push(array.splice(0,2).join(''), 2));

We could even create a function with this:

function splitStringBySegmentLength(source, segmentLength) {
    if (!segmentLength || segmentLength < 1) throw Error('Segment length must be defined and greater than/equal to 1');
    const target = [];
    for (
        const array = Array.from(source);
        array.length;
        target.push(array.splice(0,segmentLength).join('')));
    return target;
}

Then you can call the function easily in a reusable manner:

const source = "8d7f66a9273fc766cd66d1d";
const target = splitStringBySegmentLength(source, 2);

Cheers

A very naive solution, that doesn't involve regex would be to perform a string replace on your delimiter along the lines of (assuming comma for delimiter):

string.replace(FullString, "," , "~,~")

Where you can replace tilda (~) with an appropriate unique delimiter.

Then if you do a split on your new delimiter then i believe you will get the desired result.

A multi-producers and multi-consumers example, verified. It should be easy to modify it to cover other cases, single/multi producers, single/multi consumers.

from multiprocessing import Process, JoinableQueue
import time
import os

q = JoinableQueue()

def producer():
    for item in range(30):
        time.sleep(2)
        q.put(item)
    pid = os.getpid()
    print(f'producer {pid} done')


def worker():
    while True:
        item = q.get()
        pid = os.getpid()
        print(f'pid {pid} Working on {item}')
        print(f'pid {pid} Finished {item}')
        q.task_done()

for i in range(5):
    p = Process(target=worker, daemon=True).start()

# send thirty task requests to the worker
producers = []
for i in range(2):
    p = Process(target=producer)
    producers.append(p)
    p.start()

# make sure producers done
for p in producers:
    p.join()

# block until all workers are done
q.join()
print('All work completed')

Explanation:

1. Two producers and five consumers in this example.
2. JoinableQueue is used to make sure all elements stored in queue will be processed. 'task_done' is for worker to notify an element is done. 'q.join()' will wait for all elements marked as done.
3. With #2, there is no need to join wait for every worker.
4. But it is important to join wait for every producer to store element into queue. Otherwise, program exit immediately.

How to get the height of the navigation bar and status bar. This code works for me on some Huawei devices and Samsung devices. Egis's solution above is good, however, it is still incorrect on some devices. So, I improved it.

This is code to get the height of status bar

private fun getStatusBarHeight(resources: Resources): Int {
        var result = 0
        val resourceId = resources.getIdentifier("status_bar_height", "dimen", "android")
        if (resourceId > 0) {
            result = resources.getDimensionPixelSize(resourceId)
        }
        return result
    }

This method always returns the height of navigation bar even when the navigation bar is hidden.

private fun getNavigationBarHeight(resources: Resources): Int {
    val resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android")
    return if (resourceId > 0) {
        resources.getDimensionPixelSize(resourceId)
    } else 0
}

NOTE: on Samsung A70, this method returns the height of the status bar + height of the navigation bar. On other devices (Huawei), it only returns the height of the Navigation bar and returns 0 when the navigation bar is hidden.

private fun getNavigationBarHeight(): Int {
        val display = activity?.windowManager?.defaultDisplay
        return if (display == null) {
            0
        } else {
            val realMetrics = DisplayMetrics()
            display.getRealMetrics(realMetrics)
            val metrics = DisplayMetrics()
            display.getMetrics(metrics)
            realMetrics.heightPixels - metrics.heightPixels
        }
    }

This is code to get height of navigation bar and status bar

val metrics = DisplayMetrics()
        activity?.windowManager?.defaultDisplay?.getRealMetrics(metrics)

        //resources is got from activity

        //NOTE: on SamSung A70, this height = height of status bar + height of Navigation bar
        //On other devices (Huawei), this height = height of Navigation bar
        val navigationBarHeightOrNavigationBarPlusStatusBarHeight = getNavigationBarHeight()

        val statusBarHeight = getStatusBarHeight(resources)
        //The method will always return the height of navigation bar even when the navigation bar was hidden.
        val realNavigationBarHeight = getNavigationBarHeight(resources)

        val realHeightOfStatusBarAndNavigationBar =
                if (navigationBarHeightOrNavigationBarPlusStatusBarHeight == 0 || navigationBarHeightOrNavigationBarPlusStatusBarHeight < statusBarHeight) {
                    //Huawei: navigation bar is hidden
                    statusBarHeight
                } else if (navigationBarHeightOrNavigationBarPlusStatusBarHeight == realNavigationBarHeight) {
                    //Huawei: navigation bar is visible
                    statusBarHeight + realNavigationBarHeight
                } else if (navigationBarHeightOrNavigationBarPlusStatusBarHeight < realNavigationBarHeight) {
                    //SamSung A70: navigation bar is still visible but it only displays as a under line
                    //navigationBarHeightOrNavigationBarPlusStatusBarHeight = navigationBarHeight'(under line) + statusBarHeight
                    navigationBarHeightOrNavigationBarPlusStatusBarHeight
                } else {
                    //SamSung A70: navigation bar is visible
                    //navigationBarHeightOrNavigationBarPlusStatusBarHeight == statusBarHeight + realNavigationBarHeight
                    navigationBarHeightOrNavigationBarPlusStatusBarHeight
                }

If your using jQuery, it's parseJSON function can be used and is preferable to JavaScript's native eval() function.

This is default by iOS7 design. try to do the below:

[tableView setSeparatorInset:UIEdgeInsetsMake(0, 0, 0, 0)];

You can set the 'Separator Inset' from the storyboard:

Try this code. It works for me:

unzip(zipfile="<directory and filename>",
      exdir="<directory where the content will be extracted>")

Example:

unzip(zipfile="./data/Data.zip",exdir="./data")

One of the simplest ways to count number of objects in s3 is:

Step 1: Select root folder

Step 2: Click on Actions -> Delete (obviously, be careful - don't delete it)

Step 3: Wait for a few mins aws will show you number of objects and its total size.

First create a class to represent your json data.

public class MyFlightDto
{
    public string err_code { get; set; }
    public string org { get; set; } 
    public string flight_date { get; set; }
    // Fill the missing properties for your data
}

Using Newtonsoft JSON serializer to Deserialize a json string to it's corresponding class object.

var jsonInput = "{ org:'myOrg',des:'hello'}"; 
MyFlightDto flight = Newtonsoft.Json.JsonConvert.DeserializeObject<MyFlightDto>(jsonInput);

Or Use JavaScriptSerializer to convert it to a class(not recommended as the newtonsoft json serializer seems to perform better).

string jsonInput="have your valid json input here"; //
JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();
Customer objCustomer  = jsonSerializer.Deserialize<Customer >(jsonInput)

Assuming you want to convert it to a Customer classe's instance. Your class should looks similar to the JSON structure (Properties)

I wrote a function wrapper called bar() for barplot() to do what you are trying to do here, since I need to do similar things frequently. The Github link to the function is here. After copying and pasting it into R, you do

bar(dv = Species, 
    factors = c(Category, Reason), 
    dataframe = Reasonstats, 
    errbar = FALSE, 
    ylim=c(0, 140))  #I increased the upper y-limit to accommodate the legend. 

The one convenience is that it will put a legend on the plot using the names of the levels in your categorical variable (e.g., "Decline" and "Improved"). If each of your levels has multiple observations, it can also plot the error bars (which does not apply here, hence errbar=FALSE

if all that is your code you forgot to close the main method

everything else sounds good to me

public class LuisRp3 {

public static void main(String[] args) throws FileNotFoundException  {

    java.io.File newFile = new java.io.File("LuisRamosp4.txt");

    if (newFile.exists()) {
        newFile.delete();
    }

    System.setOut(new PrintStream(newFile));

    Guitar guitar = new Guitar(); 
}}

try that

We can delete a key from a Python dictionary by the some of the following approaches.

Using the del keyword; it's almost the same approach like you did though -

 myDict = {'one': 100, 'two': 200, 'three': 300 }
 print(myDict)  # {'one': 100, 'two': 200, 'three': 300}
 if myDict.get('one') : del myDict['one']
 print(myDict)  # {'two': 200, 'three': 300}

Or

We can do like the following:

But one should keep in mind that, in this process actually it won't delete any key from the dictionary rather than making a specific key excluded from that dictionary. In addition, I observed that it returned a dictionary which was not ordered the same as myDict.

myDict = {'one': 100, 'two': 200, 'three': 300, 'four': 400, 'five': 500}
{key:value for key, value in myDict.items() if key != 'one'}

If we run it in the shell, it'll execute something like {'five': 500, 'four': 400, 'three': 300, 'two': 200} - notice that it's not the same ordered as myDict. Again if we try to print myDict, then we can see all keys including which we excluded from the dictionary by this approach. However, we can make a new dictionary by assigning the following statement into a variable:

var = {key:value for key, value in myDict.items() if key != 'one'}

Now if we try to print it, then it'll follow the parent order:

print(var) # {'two': 200, 'three': 300, 'four': 400, 'five': 500}

Or

Using the pop() method.

myDict = {'one': 100, 'two': 200, 'three': 300}
print(myDict)

if myDict.get('one') : myDict.pop('one')
print(myDict)  # {'two': 200, 'three': 300}

The difference between del and pop is that, using pop() method, we can actually store the key's value if needed, like the following:

myDict = {'one': 100, 'two': 200, 'three': 300}
if myDict.get('one') : var = myDict.pop('one')
print(myDict) # {'two': 200, 'three': 300}
print(var)    # 100

Fork this gist for future reference, if you find this useful.

SELECT P.*
FROM primary_table P
LEFT JOIN secondary_table S on P.id = S.p_id
WHERE S.p_id IS NULL

You can use beforeShowDay to do this

The following example disables dates 14 March 2013 thru 16 March 2013

var array = ["2013-03-14","2013-03-15","2013-03-16"]

$('input').datepicker({
    beforeShowDay: function(date){
        var string = jQuery.datepicker.formatDate('yy-mm-dd', date);
        return [ array.indexOf(string) == -1 ]
    }
});

From Wikipedia Media type,

A media type is composed of a type, a subtype, and optional parameters. As an example, an HTML file might be designated text/html; charset=UTF-8.

Media type consists of top-level type name and sub-type name, which is further structured into so-called "trees".

top-level type name / subtype name [ ; parameters ]

top-level type name / [ tree. ] subtype name [ +suffix ] [ ; parameters ]

All media types should be registered using the IANA registration procedures. Currently the following trees are created: standard, vendor, personal or vanity, unregistered x.

Standard:

Media types in the standards tree do not use any tree facet (prefix).

type / media type name [+suffix]

Examples: "application/xhtml+xml", "image/png"

Vendor:

Vendor tree is used for media types associated with publicly available products. It uses vnd. facet.

type / vnd. media type name [+suffix] - used in the case of well-known producer

type / vnd. producer's name followed by media type name [+suffix] - producer's name must be approved by IANA

type / vnd. producer's name followed by product's name [+suffix] - producer's name must be approved by IANA

Personal or Vanity tree:

Personal or Vanity tree includes media types created experimentally or as part of products that are not distributed commercially. It uses prs. facet.

type / prs. media type name [+suffix]

Unregistered x. tree:

The "x." tree may be used for media types intended exclusively for use in private, local environments and only with the active agreement of the parties exchanging them. Types in this tree cannot be registered.

According to the previous version of RFC 6838 - obsoleted RFC 2048 (published in November 1996) it should rarely, if ever, be necessary to use unregistered experimental types, and as such use of both "x-" and "x." forms is discouraged. Previous versions of that RFC - RFC 1590 and RFC 1521 stated that the use of "x-" notation for the sub-type name may be used for unregistered and private sub-types, but this recommendation was obsoleted in November 1996.

type / x. media type name [+suffix]

So its clear that the standard type MIME type application/pdf is the appropriate one to use while you should avoid using the obsolete and unregistered x- media type as stated in RFC 2048 and RFC 6838.

    'Dog' : 'Bark'
};
_.omit(thisIsObject,'Cow'); //It will return a new object

=> {'Cat' : 'Meow', 'Dog' : 'Bark'}  //result

If you want to modify the current object, assign the returning object to the current object.

thisIsObject = _.omit(thisIsObject,'Cow');

With pure JavaScript, use:

delete thisIsObject['Cow'];

Another option with pure JavaScript.

thisIsObject.cow = undefined;

thisIsObject = JSON.parse(JSON.stringify(thisIsObject ));

I guess this what you are exactly looking for

    def findPath(i_file) :
        lines = open( i_file ).readlines()
        for line in lines :
            if line.startswith( "Path=" ):
                output_line=line[(line.find("Path=")+len("Path=")):]
                return output_line

Its easy, just wrap it in a relative box like so:

<div class="relative">
 <div class="absolute">LOGO</div>
</div>

The relative box has a margin: 0 Auto; and, important, a width...

Per Mozilla's Map documentation, you can initialize as follows:

private _gridOptions:Map<string, Array<string>> = 
    new Map([
        ["1", ["test"]],
        ["2", ["test2"]]
    ]);

There is no built-in date-only type in .NET.

The convention is to use a DateTime with the time portion set to midnight.

The static DateTime.Today property will give you today's date.

Extending @Eponymous's answer: It's great, but doesn't provide a general syntax. Here's what I came up with:

// Common/EnumTools.h
#pragma once

#include <array>

namespace Common {

// Here we forward-declare metafunction for mapping enums to their values.
// Since C++<23 doesn't have reflection, you have to populate it yourself :-(
// Usage: After declaring enum class E, add this overload in the namespace of E:
// inline constexpr auto allValuesArray(const E&, Commob::EnumAllValuesTag) { return std::array{E::foo, E::bar}; }
// Then `AllValues<NS::E>` will call `allValuesArray(NS::E{}, EnumAllValuesTag)` which will resolve
// by ADL.
// Just be sure to keep it sync'd with your enum!

// Here's what you want to use in, e.g., loops: "for (auto val : Common::AllValues<MyEnum>) {"

struct EnumAllValuesTag {}; // So your allValuesArray function is clearly associated with this header.

template <typename Enum>
static inline constexpr auto AllValues = allValuesArray(Enum{}, EnumAllValuesTag{});
// ^ Just "constexpr auto" or "constexpr std::array<Enum, allValuesArray(Enum{}, EnumAllValuesTag{}).size()>" didn't work on all compilers I'm using, but this did.

} // namespace Common

then in your namespace:

#include "Common/EnumTools.h"

namespace MyNamespace {

enum class MyEnum {
    foo,
    bar = 4,
    baz = 42,
};

// Making this not have to be in the `Common` namespace took some thinking,
// but is a critical feature since otherwise there's no hope in keeping it sync'd with the enum.
inline constexpr auto allValuesArray(const MyEnum&, Common::EnumAllValuesTag) {
    return std::array{ MyEnum::foo, MyEnum::bar, MyEnum::baz };
}

} // namespace MyNamespace

then wherever you need to use it:

for (const auto& e : Common::AllValues<MyNamespace::MyEnum>) { ... }

so even if you've typedef'd:

namespace YourNS {
using E = MyNamespace::MyEnum;
} // namespace YourNS

for (const auto& e : Common::AllValues<YourNS::E>) { ... }

I can't think of anything much better, short of the actual language feature everyone looking at this page want.

Future work:

1. You should be able to add a constexpr function (and so a metafunction) that filters Common::AllValues<E> to provide a Common::AllDistinctValues<E> for the case of enums with repeated numerical values like enum { foo = 0, bar = 0 };.
2. I bet there's a way to use the compiler's switch-covers-all-enum-values to write allValuesArray such that it errors if the enum has added a value.

This will give you the result you're giving as an example:

SELECT DISTINCT a, b
FROM pairs

Shorter answer: no, you must encode a space; it is correct to encode a space as +, but only in the query string; in the path you must use %20.

JSON.stringify takes more optional arguments.

Try:

 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, 4); // Indented 4 spaces
 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, "\t"); // Indented with tab

From:

How can I beautify JSON programmatically?

Should work in modern browsers, and it is included in json2.js if you need a fallback for browsers that don't support the JSON helper functions. For display purposes, put the output in a <pre> tag to get newlines to show.

I used this extension method a lot in my project. Hope it will help one of you guys.

public static bool HasClass(this HtmlNode node, params string[] classValueArray)
    {
        var classValue = node.GetAttributeValue("class", "");
        var classValues = classValue.Split(' ');
        return classValueArray.All(c => classValues.Contains(c));
    }

Here is my solution, since the above solution do not really cover the use-case, when you use RunPython.

You can access the table via the ORM with

from django.db.migrations.recorder import MigrationRecorder

>>> MigrationRecorder.Migration.objects.all()
>>> MigrationRecorder.Migration.objects.latest('id')
Out[5]: <Migration: Migration 0050_auto_20170603_1814 for model>
>>> MigrationRecorder.Migration.objects.latest('id').delete()
Out[4]: (1, {u'migrations.Migration': 1})

So you can query the tables and delete those entries that are relevant for you. This way you can modify in detail. With RynPython migrations you also need to take care of the data that was added/changed/removed. The above example only displays, how you access the table via Djang ORM.

In a recent application that I made, I used the inverted colors. With the r,g and b values in hand, just calculate (in this example, the color range varies from 0 to 255) :

r = 127-(r-127) and so on.

This should work:

/^((?!PART).)*$/

If you only wanted to exclude it from the beginning of the line (I know you don't, but just FYI), you could use this:

/^(?!PART)/

Edit (by request): Why this pattern works

The (?!...) syntax is a negative lookahead, which I've always found tough to explain. Basically, it means "whatever follows this point must not match the regular expression /PART/." The site I've linked explains this far better than I can, but I'll try to break this down:

^         #Start matching from the beginning of the string.    
(?!PART)  #This position must not be followed by the string "PART".
.         #Matches any character except line breaks (it will include those in single-line mode).
$         #Match all the way until the end of the string.

The ((?!xxx).)* idiom is probably hardest to understand. As we saw, (?!PART) looks at the string ahead and says that whatever comes next can't match the subpattern /PART/. So what we're doing with ((?!xxx).)* is going through the string letter by letter and applying the rule to all of them. Each character can be anything, but if you take that character and the next few characters after it, you'd better not get the word PART.

The ^ and $ anchors are there to demand that the rule be applied to the entire string, from beginning to end. Without those anchors, any piece of the string that didn't begin with PART would be a match. Even PART itself would have matches in it, because (for example) the letter A isn't followed by the exact string PART.

Since we do have ^ and $, if PART were anywhere in the string, one of the characters would match (?=PART). and the overall match would fail. Hope that's clear enough to be helpful.

If you know what class the field is on you can access it using reflection. This example (it's in Groovy but the method calls are identical) gets a Field object for the class Foo and gets its value for the object b. It shows that you don't have to care about the exact concrete class of the object, what matters is that you know the class the field is on and that that class is either the concrete class or a superclass of the object.

groovy:000> class Foo { def stuff = "asdf"}
===> true
groovy:000> class Bar extends Foo {}
===> true
groovy:000> b = new Bar()
===> Bar@1f2be27
groovy:000> f = Foo.class.getDeclaredField('stuff')
===> private java.lang.Object Foo.stuff
groovy:000> f.getClass()
===> class java.lang.reflect.Field
groovy:000> f.setAccessible(true)
===> null
groovy:000> f.get(b)
===> asdf

The search query model lives in the scope defined by the ng-controller="whatever" directive. So if you want to bind the query model to <title>, you have to move the ngController declaration to an HTML element that is a common parent to both the body and title elements:

<html ng-app="phonecatApp" ng-controller="PhoneListCtrl">

Ref: https://docs.angularjs.org/tutorial/step_03

To find whether no. is prime or not C++:

#include<iostream>
#include<cmath>

using namespace std;
int main(){

int n, counter=0;

cout <<"Enter a number to check whether it is prime or not \n";
cin>>n;

  for(int i=2; i<=n-1;i++) {
    if (n%i==0) {
      cout<<n<<" is NOT a prime number \n";
      break;
    }
    counter++;
                }
    //cout<<"Value n is "<<n<<endl;
    //cout << "number of times counter run is "<<counter << endl;
    if (counter == n-2)
      cout << n<< " is prime \n";
   return 0;
}

To find in the parent of the iFrame use:

$('#parentPrice', window.parent.document).html();

The second parameter for the $() wrapper is the context in which to search. This defaults to document.

Just to complete all the answers with some features of the 'living standard' - By now (in the html5-era) it is possible to do it without an 3rd party libs:

• pure/plain JS with querySelector (uses CSS-selectors):
  • select the first in DOM: document.querySelector('[data-answer="42"],[type="submit"]')
  • select all in DOM: document.querySelectorAll('[data-answer="42"],[type="submit"]')
• pure/plain CSS
  • some specific tags: [data-answer="42"],[type="submit"]
  • all tags with an specific attribute: [data-answer] or input[type]

The REPL makes it easy to learn APIs. Just run python, create an object and then ask for help:

$ python
>>> import re
>>> help(re.compile(r''))

at the command line shows, among other things:

search(...)

search(string[, pos[, endpos]]) --> match object or None. Scan through string looking for a match, and return a corresponding MatchObject instance. Return None if no position in the string matches.

so you can do

regex = re.compile(regex_txt, re.IGNORECASE)

match = regex.search(content)  # From your file reading code.
if match is not None:
  # use match

Incidentally,

regex_txt = "facebook.com"

has a . which matches any character, so re.compile("facebook.com").search("facebookkcom") is not None is true because . matches any character. Maybe

regex_txt = r"(?i)facebook\.com"

The \. matches a literal "." character instead of treating . as a special regular expression operator.

The r"..." bit means that the regular expression compiler gets the escape in \. instead of the python parser interpreting it.

The (?i) makes the regex case-insensitive like re.IGNORECASE but self-contained.

The rolling mean returns a Series you only have to add it as a new column of your DataFrame (MA) as described below.

For information, the rolling_mean function has been deprecated in pandas newer versions. I have used the new method in my example, see below a quote from the pandas documentation.

Warning Prior to version 0.18.0, pd.rolling_*, pd.expanding_*, and pd.ewm* were module level functions and are now deprecated. These are replaced by using the Rolling, Expanding and EWM. objects and a corresponding method call.

df['MA'] = df.rolling(window=5).mean()

print(df)
#             Value    MA
# Date                   
# 1989-01-02   6.11   NaN
# 1989-01-03   6.08   NaN
# 1989-01-04   6.11   NaN
# 1989-01-05   6.15   NaN
# 1989-01-09   6.25  6.14
# 1989-01-10   6.24  6.17
# 1989-01-11   6.26  6.20
# 1989-01-12   6.23  6.23
# 1989-01-13   6.28  6.25
# 1989-01-16   6.31  6.27

There are some great answers mentioned here. Another approach you could take would be to use some free SDKs available online like Atooma, tranql and Neura, that can be integrated with your Android application (it takes less than 20 min to integrate). Along with giving you the accurate location of your user, it can also give you good insights about your user’s activities. Also, some of them consume less than 1% of your battery

An integral type representing the smallest value possible. In other words your program should think in cents not in dollars/euros.

This should not stop you from having the gui translate it back to dollars/euros.

Here's my take:

timeSince(123456) => "1 day, 10 hours, 17 minutes, 36 seconds"

And the code:

function timeSince(date, longText) {
    let seconds = null;
    let leadingText = null;

    if (date instanceof Date) {
        seconds = Math.floor((new Date() - date) / 1000);
        if (seconds < 0) {
            leadingText = " from now";
        } else {
            leadingText = " ago";
        }
        seconds = Math.abs(seconds);
    } else {
        seconds = date;
        leadingText = "";
    }

    const intervals = [
        [31536000, "year"  ],
        [ 2592000, "month" ],
        [   86400, "day"   ],
        [    3600, "hour"  ],
        [      60, "minute"],
        [       1, "second"],
    ];

    let interval = seconds;
    let intervalStrings = [];
    for (let i = 0; i < intervals.length; i++) {
        let divResult = Math.floor(interval / intervals[i][0]);
        if (divResult > 0) {
            intervalStrings.push(divResult + " " + intervals[i][1] + ((divResult > 1) ? "s" : ""));
            interval = interval % intervals[i][0];
            if (!longText) {
                break;
            }
        }
    }
    let intStr = intervalStrings.join(", ");

    return intStr + leadingText;
}

For people wanting a quick solution to this problem:

<dependency>
  <groupId>LIB_NAME</groupId>
  <artifactId>LIB_NAME</artifactId>
  <version>1.0.0</version>
  <scope>system</scope>
  <systemPath>${basedir}/WebContent/WEB-INF/lib/YOUR_LIB.jar</systemPath>
</dependency>

just give your library a unique groupID and artifact name and point to where it is in the file system. You are good to go.

Of course this is a dirty quick fix that will ONLY work on your machine and if you don't change the path to the libs. But some times, that's all you want, to run and do a few tests.

EDIT: just re-red the question and realised the user was already using my solution as a temporary fix. I'll leave my answer as a quick help for others that come to this question. If anyone disagrees with this please leave me a comment. :)

It's as simple as:

if (value.compareTo(BigDecimal.ZERO) > 0)

The documentation for compareTo actually specifies that it will return -1, 0 or 1, but the more general Comparable<T>.compareTo method only guarantees less than zero, zero, or greater than zero for the appropriate three cases - so I typically just stick to that comparison.

You only need to do one thing. Run session_object.clear() and then save the new object. This will clear the session (as aptly named) and remove the offending duplicate object from your session.

Just wanted to add to an old thread to hopefully aid other people. I needed programmatically add a cert to the firefox database using a GPO, this was how I did it for Windows

1, First download and unzip the precompiled firefox NSS nss-3.13.5-nspr-4.9.1-compiled-x86.zip

2, Add the cert manually to firefox Options-->Advanced--Certificates-->Authorities-->Import

3, from the downloaded NSS package, run

certutil -L -d c:\users\[username]\appdata\roaming\mozilla\firefox\[profile].default    

4, The above query will show you the certificate name and Trust Attributes e.g.

my company Ltd                                CT,C,C    

5, Delete the certificate in step 2. Options-->Advanced--Certificates-->Authorities-->Delete

6, Create a powershell script using the information from step 4 as follows. This script will get the users profile path and add the certificate. This only works if the user has one firefox profile (need somehow to retrieve the users firefox folder profile name)

#Script adds Radius Certificate to independent Firefox certificate store since the browser does not use the Windows built in certificate store    


#Get Firefox profile cert8.db file from users windows profile path
$ProfilePath = "C:\Users\" + $env:username + "\AppData\Roaming\Mozilla\Firefox\Profiles\"
$ProfilePath = $ProfilePath + (Get-ChildItem $ProfilePath | ForEach-Object { $_.Name }).ToString()

#Update firefox cert8.db file with Radius Certificate
certutil -A -n "UK my company" -t "CT,C,C" -i CertNameToAdd.crt -d $ProfilePath    

7, Create GPO as a User Configuration to run the PowerShell script

Hope that helps save someone time

You don't need --header "Content-Length: $LENGTH".

curl --request POST --data-binary "@template_entry.xml" $URL

Note that GET request does not support content body widely.

Also remember that POST request have 2 different coding schema. This is first form:

  $ nc -l -p 6666 &
  $ curl  --request POST --data-binary "@README" http://localhost:6666

POST / HTTP/1.1
User-Agent: curl/7.21.0 (x86_64-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6

You probably request this:

-F/--form name=content
           (HTTP) This lets curl emulate a filled-in form in
              which a user has pressed the submit button. This
              causes curl to POST data using the Content- Type
              multipart/form-data according to RFC2388. This
              enables uploading of binary files etc. To force the
              'content' part to be a file, prefix the file name
              with an @ sign. To just get the content part from a
              file, prefix the file name with the symbol <. The
              difference between @ and < is then that @ makes a
              file get attached in the post as a file upload,
              while the < makes a text field and just get the
              contents for that text field from a file.

The simplest way you can do this is to use java script. For example, <input type="button" value="load" onclick="window.location='userpage.jsp'" >

Its better to access the count with the laravels count method

$count = Model::where('status','=','1')->count();

or

$count = Model::count();

Try this

products.sort(function (a, b) {
  return a.title.rendered - b.title.rendered;
});

OR

You can import lodash/underscore library, it has many build functions available for manipulating, filtering, sorting the array and all.

Using underscore: (below one is just an example)

import * as _ from 'underscore';
let sortedArray = _.sortBy(array, 'title'); 

You have to call close() on the GZIPOutputStream before you attempt to read it. The final bytes of the file will only be written when the file is actually closed. (This is irrespective of any explicit buffering in the output stack. The stream only knows to compress and write the last bytes when you tell it to close. A flush() probably won't help ... though calling finish() instead of close() should work. Look at the javadocs.)

Here's the correct code (in Java);

package test;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;

public class GZipTest {

    public static void main(String[] args) throws
                FileNotFoundException, IOException {
        String name = "/tmp/test";
        GZIPOutputStream gz = new GZIPOutputStream(new FileOutputStream(name));
        gz.write(10);
        gz.close();       // Remove this to reproduce the reported bug
        System.out.println(new GZIPInputStream(new FileInputStream(name)).read());
    }
}

(I've not implemented resource management or exception handling / reporting properly as they are not relevant to the purpose of this code. Don't treat this as an example of "good code".)

In addition to excellent Craig Ringer's post and depesz's blog post, if you would like to speed up your inserts through ODBC (psqlodbc) interface by using prepared-statement inserts inside a transaction, there are a few extra things you need to do to make it work fast:

1. Set the level-of-rollback-on-errors to "Transaction" by specifying Protocol=-1 in the connection string. By default psqlodbc uses "Statement" level, which creates a SAVEPOINT for each statement rather than an entire transaction, making inserts slower.
2. Use server-side prepared statements by specifying UseServerSidePrepare=1 in the connection string. Without this option the client sends the entire insert statement along with each row being inserted.
3. Disable auto-commit on each statement using SQLSetConnectAttr(conn, SQL_ATTR_AUTOCOMMIT, reinterpret_cast<SQLPOINTER>(SQL_AUTOCOMMIT_OFF), 0);
4. Once all rows have been inserted, commit the transaction using SQLEndTran(SQL_HANDLE_DBC, conn, SQL_COMMIT);. There is no need to explicitly open a transaction.

Unfortunately, psqlodbc "implements" SQLBulkOperations by issuing a series of unprepared insert statements, so that to achieve the fastest insert one needs to code up the above steps manually.

    Node result = null;
    try {
        document = dbf.newDocumentBuilder().parse(fXmlFile);
        XPath xPath = XPathFactory.newInstance().newXPath();
        String xpathStr = "//Envelope//Header";
        result = (Node) xPath.evaluate(xpathStr, document, XPathConstants.NODE);
        System.out.println(nodeToString(result));
    } catch (SAXException | IOException | ParserConfigurationException | XPathExpressionException
            | TransformerException e) {
        e.printStackTrace();
    }
}

private static String nodeToString(Node node) throws TransformerException {
    StringWriter buf = new StringWriter();
    Transformer xform = TransformerFactory.newInstance().newTransformer();
    xform.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
    xform.transform(new DOMSource(node), new StreamResult(buf));
    return (buf.toString());
}

Now if you want only the xml like below

<Friends>
   <friend>
      <Name>Testabc</Name>
      <Age>12121</Age>
      <Phone>Testpqr</Phone>
   </friend>
</Friends>

You need to change the

String xpathStr = "//Envelope//Header"; to String xpathStr = "//Envelope//Header/*";

If you're running Bootstrap 4, it may be due to ".fade:not(.show) { opacity: 0 }" in the Bootstrap css and your modal doesn't have class 'show'. And the reason it doesn't have class 'show' may be due to your page not loading jQuery, Popper, and Bootstrap Javascript files.

(The Bootstrap Javascript will add the class 'show' to your dialog automagically.)

Reference: https://getbootstrap.com/docs/4.3/getting-started/introduction/

document.getElementById('loginSubmit').submit();

or, use the same code as the onclick handler:

changeAction('submitInput','loginForm');
document.forms['loginForm'].submit();

(Though that onclick handler is kind of stupidly-written: document.forms['loginForm'] could be replaced with this.)

int myInt = 65;

char myChar = (char)myInt;  // myChar should now be the letter A

char[20] myString = {0}; // make an empty string.

myString[0] = myChar;
myString[1] = myChar; // Now myString is "AA"

This should all be found in any intro to C book, or by some basic online searching.

>>> s = ['a','b','c']   
>>> f = ['a','b','d','c']  
>>> ss= set(s)  
>>> fs =set(f)  
>>> print ss.intersection(fs)   
   **set(['a', 'c', 'b'])**  
>>> print ss.union(fs)        
   **set(['a', 'c', 'b', 'd'])**  
>>> print ss.union(fs)  - ss.intersection(fs)   
   **set(['d'])**

Adding to Eric Jablow's answer, here is a possible solution (it worked for me - linux mint 14 /nadia)

find /path/to/search/ -type f -name "glob-to-find-files" | xargs cp -t /target/path/

You can refer to "How can I use xargs to copy files that have spaces and quotes in their names?" as well.

You need jQuery see bootstrap's basic template

Note that I don't recommend a fixed IP for containers in Docker unless you're doing something that allows routing from outside to the inside of your container network (e.g. macvlan). DNS is already there for service discovery inside of the container network and supports container scaling. And outside the container network, you should use exposed ports on the host. With that disclaimer, here's the compose file you want:

version: '2'

services:
  mysql:
    container_name: mysql
    image: mysql:latest
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=root
    ports:
     - "3306:3306"
    networks:
      vpcbr:
        ipv4_address: 10.5.0.5

  apigw-tomcat:
    container_name: apigw-tomcat
    build: tomcat/.
    ports:
     - "8080:8080"
     - "8009:8009"
    networks:
      vpcbr:
        ipv4_address: 10.5.0.6
    depends_on:
     - mysql

networks:
  vpcbr:
    driver: bridge
    ipam:
     config:
       - subnet: 10.5.0.0/16
         gateway: 10.5.0.1

The DOM methods getElementById(), nextSibling(), childNodes[n], parentNode() and so on return null (defined but having no value) when the call does not return a node object.

The property is defined, but the object it refers to does not exist.

This is one of the few times you may not want to test for equality-

if(x!==undefined) will be true for a null value

but if(x!= undefined) will be true (only) for values that are not either undefined or null.

Your problem is that you're converting the button into an HTML snippet when you add it to the table, but that snippet is not the same object as the one that has the click handler on it.

$("#myButton").click(function () {
    var test = $('<button>Test</button>').click(function () {
        alert('hi');
    });

    $("#nodeAttributeHeader").css('display', 'table-row'); // NB: changed

    var tr = $('<tr>').insertBefore('#addNodeTable tr:last');
    var td = $('<td>').append(test).appendTo(tr);
});

This looks like a behavior difference in the handling of \s between grep 2.5 and newer versions (a bug in old grep?). I confirm your result with grep 2.5.4, but all four of your greps do work when using grep 2.6.3 (Ubuntu 10.10).

Note:

GNU grep 2.5.4
echo "foo bar" | grep "\s"
   (doesn't match)

whereas

GNU grep 2.6.3
echo "foo bar" | grep "\s"
foo bar

Probably less trouble (as \s is not documented):

Both GNU greps
echo "foo bar" | grep "[[:space:]]"
foo bar

My advice is to avoid using \s ... use [ \t]* or [[:space:]] or something like it instead.

A good place to start is the sample application provided on the developer docs.

• Guidelines would be to just make it as usable as possible. Take a look at the others available on the market to see what you should be aiming for
• Yes, services can do most things, including internet; provided you have asked for those permissions
• You can open activities and do anything you like n those if you run into a problem with doing some things in the keyboard. For example HTC's keyboard has a button to open the settings activity, and another to open a dialog to change languages.

Take a look at other IME's to see what you should be aiming for. Some (like the official one) are open source.

Just in case you were wondering how to rename columns during aggregation, here's how for

pandas >= 0.25: Named Aggregation

df.groupby('Company Name')['Amount'].agg(MySum='sum', MyCount='count')

Or,

df.groupby('Company Name').agg(MySum=('Amount', 'sum'), MyCount=('Amount', 'count'))

                       MySum  MyCount
Company Name                       
Vifor Pharma UK Ltd  4207.93        5

While a = 'foo' if True else 'bar' is the more modern way of doing the ternary if statement (python 2.5+), a 1-to-1 equivalent of your version might be:

a = (b == True and "123" or "456" )

... which in python should be shortened to:

a = b is True and "123" or "456"

... or if you simply want to test the truthfulness of b's value in general...

a = b and "123" or "456"

? : can literally be swapped out for and or

Windows 10 and Android Studio: Ctrl + / (on small num pad), don't use Ctrl + Shift-7!

See here: Physical Vs Virtual Memory

Virtual memory is stored on the hard drive and is used when the RAM is filled. Physical memory is limited to the size of the RAM chips installed in the computer. Virtual memory is limited by the size of the hard drive, so virtual memory has the capability for more storage.

To put it in another way, can we replicate the appearance of these text views without using the android:textAppearance attribute?

Like biegleux already said:

• small represents 14sp
• medium represents 18sp
• large represents 22sp

If you want to use the small, medium or large value on any text in your Android app, you can just create a dimens.xml file in your values folder and define the text size there with the following 3 lines:

<dimen name="text_size_small">14sp</dimen>
<dimen name="text_size_medium">18sp</dimen>
<dimen name="text_size_large">22sp</dimen>

Here is an example for a TextView with large text from the dimens.xml file:

<TextView
  android:id="@+id/hello_world"
  android:text="hello world"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:textSize="@dimen/text_size_large"/>

This works for me:

 "jest": {
    "collectCoverage": true,
    "coverageReporters": ["json", "html"]
  },
  "scripts": {
    "test": "jest  --coverage"
  },

Run:

yarn/npm test

You can use int casting which allows the base specification.

int(b, 2)  # Convert a binary string to a decimal int.

Oracle JRockit, which can handle a non-contiguous heap, can have a Java heap size of 2.85 GB on Windows 2003/XP with the /3GB switch. It seems that fragmentation can have quite an impact on how large a Java heap can be.

Python 3:

my_list = [*range(1001)]

If you can organize the values in the array in sorted order, then you can use Arrays.binarySearch(). Otherwise you'll have to write a loop and to a linear search. If you plan to have a large (more than a few dozen) strings in the array, consider using a Set instead.

Post.find().sort({date:-1}, function(err, posts){
});

Should work as well

EDIT:

You can also try using this if you get the error sort() only takes 1 Argument :

Post.find({}, {
    '_id': 0,    // select keys to return here
}, {sort: '-date'}, function(err, posts) {
    // use it here
});

I've got this exact error, but in my case I was binding values for the LIMIT clause without specifying the type. I'm just dropping this here in case somebody gets this error for the same reason. Without specifying the type LIMIT :limit OFFSET :offset; resulted in LIMIT '10' OFFSET '1'; instead of LIMIT 10 OFFSET 1;. What helps to correct that is the following:

$stmt->bindParam(':limit', intval($limit, 10), \PDO::PARAM_INT);
$stmt->bindParam(':offset', intval($offset, 10), \PDO::PARAM_INT);

To manually compile OpenSSL, do as follows:

$ cd /usr/src

$ wget https://www.openssl.org/source/openssl-1.0.1g.tar.gz -O openssl-1.0.1g.tar.gz

$ tar -zxf openssl-1.0.1g.tar.gz

$ cd openssl-1.0.1g

$ ./config

$ make

$ make test

$ make install

$ openssl version

If it shows the old version, do the steps below.

$ mv /usr/bin/openssl /root/

$ ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl
openssl version

This answer applies when a string is manually entered, not when it's read from somewhere.

A traditional variable-width CSV is unreadable for storing data as a string variable. Especially for use inside a .py file, consider fixed-width pipe-separated data instead. Various IDEs and editors may have a plugin to format pipe-separated text into a neat table.

Using read_csv

Store the following in a utility module, e.g. util/pandas.py. An example is included in the function's docstring.

import io
import re

import pandas as pd


def read_psv(str_input: str, **kwargs) -> pd.DataFrame:
    """Read a Pandas object from a pipe-separated table contained within a string.

    Input example:
        | int_score | ext_score | eligible |
        |           | 701       | True     |
        | 221.3     | 0         | False    |
        |           | 576       | True     |
        | 300       | 600       | True     |

    The leading and trailing pipes are optional, but if one is present,
    so must be the other.

    `kwargs` are passed to `read_csv`. They must not include `sep`.

    In PyCharm, the "Pipe Table Formatter" plugin has a "Format" feature that can 
    be used to neatly format a table.

    Ref: https://stackoverflow.com/a/46471952/
    """

    substitutions = [
        ('^ *', ''),  # Remove leading spaces
        (' *$', ''),  # Remove trailing spaces
        (r' *\| *', '|'),  # Remove spaces between columns
    ]
    if all(line.lstrip().startswith('|') and line.rstrip().endswith('|') for line in str_input.strip().split('\n')):
        substitutions.extend([
            (r'^\|', ''),  # Remove redundant leading delimiter
            (r'\|$', ''),  # Remove redundant trailing delimiter
        ])
    for pattern, replacement in substitutions:
        str_input = re.sub(pattern, replacement, str_input, flags=re.MULTILINE)
    return pd.read_csv(io.StringIO(str_input), sep='|', **kwargs)

Non-working alternatives

The code below doesn't work properly because it adds an empty column on both the left and right sides.

df = pd.read_csv(io.StringIO(df_str), sep=r'\s*\|\s*', engine='python')

As for read_fwf, it doesn't actually use so many of the optional kwargs that read_csv accepts and uses. As such, it shouldn't be used at all for pipe-separated data.

You use ttk.Frame, bg option does not work for it. You should create style and apply it to the frame.

from tkinter import *
from tkinter.ttk import * 

root = Tk()

s = Style()
s.configure('My.TFrame', background='red')

mail1 = Frame(root, style='My.TFrame')
mail1.place(height=70, width=400, x=83, y=109)
mail1.config()
root.mainloop()

What do you mean by "initialize an array to zero"? Arrays don't contain "zero" -- they can contain "zero elements", which is the same as "an empty list". Or, you could have an array with one element, where that element is a zero: my @array = (0);

my @array = (); should work just fine -- it allocates a new array called @array, and then assigns it the empty list, (). Note that this is identical to simply saying my @array;, since the initial value of a new array is the empty list anyway.

Are you sure you are getting an error from this line, and not somewhere else in your code? Ensure you have use strict; use warnings; in your module or script, and check the line number of the error you get. (Posting some contextual code here might help, too.)

Completeness

You need to check both $mysqli and $statement. If they are false, you need to output $mysqli->error or $statement->error respectively.

Efficiency

For simple scripts that may terminate, I use simple one-liners that trigger a PHP error with the message. For a more complex application, an error warning system should be activated instead, for example by throwing an exception.

Usage example 1: Simple script

# This is in a simple command line script
$mysqli = new mysqli('localhost', 'buzUser', 'buzPassword');
$q = "UPDATE foo SET bar=1";
($statement = $mysqli->prepare($q)) or trigger_error($mysqli->error, E_USER_ERROR);
$statement->execute() or trigger_error($statement->error, E_USER_ERROR);

Usage example 2: Application

# This is part of an application
class FuzDatabaseException extends Exception {
}

class Foo {
  public $mysqli;
  public function __construct(mysqli $mysqli) {
    $this->mysqli = $mysqli;
  }
  public function updateBar() {
    $q = "UPDATE foo SET bar=1";
    $statement = $this->mysqli->prepare($q);
    if (!$statement) {
      throw new FuzDatabaseException($mysqli->error);
    }

    if (!$statement->execute()) {
      throw new FuzDatabaseException($statement->error);
    }
  }
}

$foo = new Foo(new mysqli('localhost','buzUser','buzPassword'));
try {
  $foo->updateBar();
} catch (FuzDatabaseException $e)
  $msg = $e->getMessage();
  // Now send warning emails, write log
}

.bar {
background - color: blue;
height: 40 px;
width: 40 px;
border - style: solid;
border - right - width: 1300 px;
border - radius: 40 px;
animation - name: Load;
animation - duration: 11 s;
position: relative;
animation - iteration - count: 1;
animation - fill - mode: forwards;
}

@keyframes Load {

}

Here if you are referring to my previous answers Here is an Update. 1. Compile would be removed from the dependencies after 2018.

a new version build Gradle is available.

Use the above-noted stuff it will help you to resolve the errors. It is needed for the developers who are working after March 2018. Also, maven update might be needed. All above answers will not work on the Android Studio 3.1. Hence Above code block is needed to be changed if you are using 3.1. See also I replaced compile by implementation.

I would add a div around the image and make the image change in opacity on hover and add an inset box shadow to the div on hover.

img:hover{
    opacity:.5;
}
.image:hover{
    box-shadow: inset 10px 10px 100px 100px #000;
}

<div class="image"><img src="image.jpg" /></div>

The number of rows of a list of lists would be: len(A) and the number of columns len(A[0]) given that all rows have the same number of columns, i.e. all lists in each index are of the same size.

The answer of Pascal Thivent helped me out, too. But if you manage your plugins within the <pluginManagement>element, you have to define the assembly again outside of the plugin management, or else the dependencies are not packed in the jar if you run mvn install.

Not what you asked but may be useful nevertheless.

Of course you can do the same thing with matrix formulas. Just read the result of the cell that contains:

Cell A1="Text to search"
Cells A2:C20=Range to search for

=COUNT(SEARCH(A1;A2:C20;1))

Remember that entering matrix formulas needs CTRL+SHIFT+ENTER, not just ENTER. After, it should look like :

{=COUNT(SEARCH(A1;A2:C20;1))}

To send an mms for Android 4.0 api 14 or higher without permission to write apn settings, you can use this library: Retrieve mnc and mcc codes from android, then call

Carrier c = Carrier.getCarrier(mcc, mnc);
if (c != null) {
    APN a = c.getAPN();
    if (a != null) {
        String mmsc = a.mmsc;
        String mmsproxy = a.proxy; //"" if none
        int mmsport = a.port; //0 if none
    }
}

To use this, add Jsoup and droid prism jar to the build path, and import com.droidprism.*;

It seems no one has mentioned about using nonNull method which also can be used with streams in Java 8 to remove null (but not empty) as:

String[] origArray = {"Apple", "", "Cat", "Dog", "", null};
String[] cleanedArray = Arrays.stream(firstArray).filter(Objects::nonNull).toArray(String[]::new);
System.out.println(Arrays.toString(origArray));
System.out.println(Arrays.toString(cleanedArray));

And the output is:

[Apple, , Cat, Dog, , null]

[Apple, , Cat, Dog, ]

If we want to incorporate empty also then we can define a utility method (in class Utils(say)):

public static boolean isEmpty(String string) {
        return (string != null && string.isEmpty());
    }

And then use it to filter the items as:

Arrays.stream(firstArray).filter(Utils::isEmpty).toArray(String[]::new);

I believe Apache common also provides a utility method StringUtils.isNotEmpty which can also be used.

If you are using gcc, it's possible to use:

const char * enum_to_string_map[]={ [enum1]='string1', [enum2]='string2'};

Then just call for instance

enum_to_string_map[enum1]

Auto Refresh Workbook for example every 5 sec. Apply to module

Public Sub Refresh()
'refresh
ActiveWorkbook.RefreshAll

alertTime = Now + TimeValue("00:00:05") 'hh:mm:ss
    Application.OnTime alertTime, "Refresh"

End Sub

Apply to Workbook on Open

Private Sub Workbook_Open()
alertTime = Now + TimeValue("00:00:05") 'hh:mm:ss
Application.OnTime alertTime, "Refresh"
End Sub

:)

var myContent = '<div id="test">Hello <span>world!</span></div>';

alert($(myContent).text());

That results in hello world. Does that answer your question?

http://jsfiddle.net/D2tEf/ for an example

filter_var()

    'options' => array('min_range' => 0)
);

if (filter_var($int, FILTER_VALIDATE_INT, $options) !== FALSE) {
 // you're good
}

I'm using this for a while now, don't know if this is still up to date with the actual PHP versions. You can use this in a one file setup, or just split it up in two files like contact.php and index.php

contact.php | Code

<?php 
error_reporting(E_ALL ^ E_NOTICE); 


if(isset($_POST['submitted'])) {


if(trim($_POST['contactName']) === '') {
    $nameError =  '<span style="margin-left:40px;">You have missed your name.</span>'; 
    $hasError = true;
} else {

Based on some answers I found here, I made myself a small helper file to source for my projects:

trycatch.sh

#!/bin/bash

function try()
{
    [[ $- = *e* ]]; SAVED_OPT_E=$?
    set +e
}

function throw()
{
    exit $1
}

function catch()
{
    export ex_code=$?
    (( $SAVED_OPT_E )) && set +e
    return $ex_code
}

function throwErrors()
{
    set -e
}

function ignoreErrors()
{
    set +e
}

here is an example how it looks like in use:

#!/bin/bash
export AnException=100
export AnotherException=101

# start with a try
try
(   # open a subshell !!!
    echo "do something"
    [ someErrorCondition ] && throw $AnException

    echo "do something more"
    executeCommandThatMightFail || throw $AnotherException

    throwErrors # automaticatly end the try block, if command-result is non-null
    echo "now on to something completely different"
    executeCommandThatMightFail

    echo "it's a wonder we came so far"
    executeCommandThatFailsForSure || true # ignore a single failing command

    ignoreErrors # ignore failures of commands until further notice
    executeCommand1ThatFailsForSure
    local result = $(executeCommand2ThatFailsForSure)
    [ result != "expected error" ] && throw $AnException # ok, if it's not an expected error, we want to bail out!
    executeCommand3ThatFailsForSure

    echo "finished"
)
# directly after closing the subshell you need to connect a group to the catch using ||
catch || {
    # now you can handle
    case $ex_code in
        $AnException)
            echo "AnException was thrown"
        ;;
        $AnotherException)
            echo "AnotherException was thrown"
        ;;
        *)
            echo "An unexpected exception was thrown"
            throw $ex_code # you can rethrow the "exception" causing the script to exit if not caught
        ;;
    esac
}

In windows, I use this PowerShell script to start it up.

You can try with following command:

sudo service mongod start

Please check the directory path whether exists or not. This error comes up if the folder doesn't exists from where you are running the command. Probably you have executed a remove command from same path in command line.

For posterity's sake, if you are trying to actually use jarsigner to sign a jar file (such as that of an applet) with a keystore, you'll need to reference jarsigner while running the command from the folder that your keystore is in:

cd "C:\Program Files\Java\jre(version#)\bin"

then

"C:\Program Files\Java\jdk(version#)\bin\jarsigner.exe" -keystore mykeystore (PATH TO YOUR .JAR)\MyJarFile.jar alias

The above might be obvious, but it took me a few tries because I was trying to call jarsigner while inside the JDK folder, which had no knowledge of where my keystore was (in the jre directory!), so I hope this will help those who would like to see a usable syntax for that situation.

Knockout.js validation is handy but it is not robust. You always have to create server side validation replica. In your case (as you use knockout.js) you are sending JSON data to server and back asynchronously, so you can make user think that he sees client side validation, but in fact it would be asynchronous server side validation.

Take a look at example here upida.cloudapp.net:8080/org.upida.example.knockout/order/create?clientId=1 This is a "Create Order" link. Try to click "save", and play with products. This example is done using upida library (there are spring mvc version and asp.net mvc of this library) from codeplex.

i was looking for some string bits conversion and got here, If the next case is for you take //it so... if you want to use the bits from a string into different bits maybe this example would help

$string="1001"; //this would be 2^0*1+....0...+2^3*1=1+8=9
$bit4=$string[0];//1
$bit3=$string[1];
$bit2=$string[2];
$bit1=$string[3];//1

Adding ?wmode=opaque to the URL seems to solve this problem for me, although I have not tested it in IE yet.

For those of you having troubles with the previously proposed solution, note that an inital ampersand will only work if you are already supplying other arguments to the URL. The first argument must have an initial question mark: http://www.example.com?first=foo&second=bar

Short answer: Use the change event. Here's a couple of practical examples. Since I misread the question, I'll include jQuery examples along with plain JavaScript. You're not gaining much, if anything, by using jQuery though.

Single checkbox

Using querySelector.

var checkbox = document.querySelector("input[name=checkbox]");

checkbox.addEventListener('change', function() {
  if (this.checked) {
    console.log("Checkbox is checked..");
  } else {
    console.log("Checkbox is not checked..");
  }
});

<input type="checkbox" name="checkbox" />

Single checkbox with jQuery

$('input[name=checkbox]').change(function() {
  if ($(this).is(':checked')) {
    console.log("Checkbox is checked..")
  } else {
    console.log("Checkbox is not checked..")
  }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<input type="checkbox" name="checkbox" />

Multiple checkboxes

Here's an example of a list of checkboxes. To select multiple elements we use querySelectorAll instead of querySelector. Then use Array.filter and Array.map to extract checked values.

// Select all checkboxes with the name 'settings' using querySelectorAll.
var checkboxes = document.querySelectorAll("input[type=checkbox][name=settings]");
let enabledSettings = []

/*
For IE11 support, replace arrow functions with normal functions and
use a polyfill for Array.forEach:
https://vanillajstoolkit.com/polyfills/arrayforeach/
*/

// Use Array.forEach to add an event listener to each checkbox.
checkboxes.forEach(function(checkbox) {
  checkbox.addEventListener('change', function() {
    enabledSettings = 
      Array.from(checkboxes) // Convert checkboxes to an array to use filter and map.
      .filter(i => i.checked) // Use Array.filter to remove unchecked checkboxes.
      .map(i => i.value) // Use Array.map to extract only the checkbox values from the array of objects.
      
    console.log(enabledSettings)
  })
});

<label>
   <input type="checkbox" name="settings" value="forcefield">
   Enable forcefield
</label>
<label>
  <input type="checkbox" name="settings" value="invisibilitycloak">
  Enable invisibility cloak
</label>
<label>
  <input type="checkbox" name="settings" value="warpspeed">
  Enable warp speed
</label>

Multiple checkboxes with jQuery

let checkboxes = $("input[type=checkbox][name=settings]")
let enabledSettings = [];

// Attach a change event handler to the checkboxes.
checkboxes.change(function() {
  enabledSettings = checkboxes
    .filter(":checked") // Filter out unchecked boxes.
    .map(function() { // Extract values using jQuery map.
      return this.value;
    }) 
    .get() // Get array.
    
  console.log(enabledSettings);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<label>
   <input type="checkbox" name="settings" value="forcefield">
   Enable forcefield
</label>
<label>
  <input type="checkbox" name="settings" value="invisibilitycloak">
  Enable invisibility cloak
</label>
<label>
  <input type="checkbox" name="settings" value="warpspeed">
  Enable warp speed
</label>

Your understanding is slightly flawed. The diamond operator is a nice feature as you don't have to repeat yourself. It makes sense to define the type once when you declare the type but just doesn't make sense to define it again on the right side. The DRY principle.

Now to explain all the fuzz about defining types. You are right that the type is removed at runtime but once you want to retrieve something out of a List with type definition you get it back as the type you've defined when declaring the list otherwise it would lose all specific features and have only the Object features except when you'd cast the retrieved object to it's original type which can sometimes be very tricky and result in a ClassCastException.

Using List<String> list = new LinkedList() will get you rawtype warnings.

My code to make animation slide up, slide down without XML

private static ObjectAnimator createBottomUpAnimation(View view,
        AnimatorListenerAdapter listener, float distance) {
    ObjectAnimator animator = ObjectAnimator.ofFloat(view, "translationY", -distance);
//        animator.setDuration(???)
    animator.removeAllListeners();
    if (listener != null) {
        animator.addListener(listener);
    }
    return animator;
}

public static ObjectAnimator createTopDownAnimation(View view, AnimatorListenerAdapter listener,
        float distance) {
    view.setTranslationY(-distance);
    ObjectAnimator animator = ObjectAnimator.ofFloat(view, "translationY", 0);
    animator.removeAllListeners();
    if (listener != null) {
        animator.addListener(listener);
    }
    return animator;
}

Using For slide down

createTopDownAnimation(myYellowView, null, myYellowView.getHeight()).start();

For slide up

createBottomUpAnimation(myYellowView, null, myYellowView.getHeight()).start();

You can do something like this:

a = [1,2,3,4,5]
b = [i**2 for i in a]

It's called a list comprehension, to make it easier for you to loop inside a list.

That looks like Smarty to me. Smarty is a template parser written in PHP.

You can read up on how to use Smarty in the documentation.

If you can't get access to the CMS's source: To view the templates in your browser, just look at what variables Smarty is using and create a PHP file that populates the used variables with dummy data.

If I remember correctly, once Smarty is set up, you can use:

$smarty->assign('nameofvar', 'some data');

to set the variables.

Yes you need an encapsulating div:

<div id="logo"><img src="logo.jpg"></div>

with something like:

#logo { height: 100px; width: 200px; overflow: hidden; }

Other solutions (padding, margin) are more tedious (in that you need to calculate the right value based on the image's dimensions) but also don't effectively allow the container to be smaller than the image.

Also, the above can be adapted much more easily for different layouts. For example, if you want the image at the bottom right:

#logo { position: relative; height: 100px; width: 200px; }
#logo img { position: absolute; right: 0; bottom: 0; }

The OP states that each plot element overwrites the previous one rather than being combined into a single plot. This can happen even with one of the many suggestions made by other answers. If you select several lines and run them together, say:

plt.plot(<X>, <Y>)
plt.plot(<X>, <Z>)

the plot elements will typically be rendered together, one layer on top of the other. But if you execute the code line-by-line, each plot will overwrite the previous one.

This perhaps is what happened to the OP. It just happened to me: I had set up a new key binding to execute code by a single key press (on spyder), but my key binding was executing only the current line. The solution was to select lines by whole blocks or to run the whole file.

What is the difference between iterators and generators? Some examples for when you would use each case would be helpful.

In summary: Iterators are objects that have an __iter__ and a __next__ (next in Python 2) method. Generators provide an easy, built-in way to create instances of Iterators.

A function with yield in it is still a function, that, when called, returns an instance of a generator object:

def a_function():
    "when called, returns generator object"
    yield

A generator expression also returns a generator:

a_generator = (i for i in range(0))

For a more in-depth exposition and examples, keep reading.

A Generator is an Iterator

Specifically, generator is a subtype of iterator.

>>> import collections, types
>>> issubclass(types.GeneratorType, collections.Iterator)
True

We can create a generator several ways. A very common and simple way to do so is with a function.

Specifically, a function with yield in it is a function, that, when called, returns a generator:

>>> def a_function():
        "just a function definition with yield in it"
        yield
>>> type(a_function)
<class 'function'>
>>> a_generator = a_function()  # when called
>>> type(a_generator)           # returns a generator
<class 'generator'>

And a generator, again, is an Iterator:

>>> isinstance(a_generator, collections.Iterator)
True

An Iterator is an Iterable

An Iterator is an Iterable,

>>> issubclass(collections.Iterator, collections.Iterable)
True

which requires an __iter__ method that returns an Iterator:

>>> collections.Iterable()
Traceback (most recent call last):
  File "<pyshell#79>", line 1, in <module>
    collections.Iterable()
TypeError: Can't instantiate abstract class Iterable with abstract methods __iter__

Some examples of iterables are the built-in tuples, lists, dictionaries, sets, frozen sets, strings, byte strings, byte arrays, ranges and memoryviews:

>>> all(isinstance(element, collections.Iterable) for element in (
        (), [], {}, set(), frozenset(), '', b'', bytearray(), range(0), memoryview(b'')))
True

Iterators require a next or __next__ method

In Python 2:

>>> collections.Iterator()
Traceback (most recent call last):
  File "<pyshell#80>", line 1, in <module>
    collections.Iterator()
TypeError: Can't instantiate abstract class Iterator with abstract methods next

And in Python 3:

>>> collections.Iterator()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: Can't instantiate abstract class Iterator with abstract methods __next__

We can get the iterators from the built-in objects (or custom objects) with the iter function:

>>> all(isinstance(iter(element), collections.Iterator) for element in (
        (), [], {}, set(), frozenset(), '', b'', bytearray(), range(0), memoryview(b'')))
True

The __iter__ method is called when you attempt to use an object with a for-loop. Then the __next__ method is called on the iterator object to get each item out for the loop. The iterator raises StopIteration when you have exhausted it, and it cannot be reused at that point.

From the documentation

From the Generator Types section of the Iterator Types section of the Built-in Types documentation:

Python’s generators provide a convenient way to implement the iterator protocol. If a container object’s __iter__() method is implemented as a generator, it will automatically return an iterator object (technically, a generator object) supplying the __iter__() and next() [__next__() in Python 3] methods. More information about generators can be found in the documentation for the yield expression.

(Emphasis added.)

So from this we learn that Generators are a (convenient) type of Iterator.

Example Iterator Objects

You might create object that implements the Iterator protocol by creating or extending your own object.

class Yes(collections.Iterator):

    def __init__(self, stop):
        self.x = 0
        self.stop = stop

    def __iter__(self):
        return self

    def next(self):
        if self.x < self.stop:
            self.x += 1
            return 'yes'
        else:
            # Iterators must raise when done, else considered broken
            raise StopIteration

    __next__ = next # Python 3 compatibility

But it's easier to simply use a Generator to do this:

def yes(stop):
    for _ in range(stop):
        yield 'yes'

Or perhaps simpler, a Generator Expression (works similarly to list comprehensions):

yes_expr = ('yes' for _ in range(stop))

They can all be used in the same way:

>>> stop = 4             
>>> for i, y1, y2, y3 in zip(range(stop), Yes(stop), yes(stop), 
                             ('yes' for _ in range(stop))):
...     print('{0}: {1} == {2} == {3}'.format(i, y1, y2, y3))
...     
0: yes == yes == yes
1: yes == yes == yes
2: yes == yes == yes
3: yes == yes == yes

Conclusion

You can use the Iterator protocol directly when you need to extend a Python object as an object that can be iterated over.

However, in the vast majority of cases, you are best suited to use yield to define a function that returns a Generator Iterator or consider Generator Expressions.

Finally, note that generators provide even more functionality as coroutines. I explain Generators, along with the yield statement, in depth on my answer to "What does the “yield” keyword do?".

Overhead is simply the more time consumption in program execution. Example ; when we call a function and its control is passed where it is defined and then its body is executed, this means that we make our CPU to run through a long process( first passing the control to other place in memory and then executing there and then passing the control back to the former position) , consequently it takes alot performance time, hence Overhead. Our goals are to reduce this overhead by using the inline during function definition and calling time, which copies the content of the function at the function call hence we dont pass the control to some other location, but continue our program in a line, hence inline.

To answer a little more conceptually:

SelectedValuePath defines which property (by its name) of the objects bound to the ListBox's ItemsSource will be used as the item's SelectedValue.

For example, if your ListBox is bound to a collection of Person objects, each of which has Name, Age, and Gender properties, SelectedValuePath=Name will cause the value of the selected Person's Name property to be returned in SelectedValue.

Note that if you override the ListBox's ControlTemplate (or apply a Style) that specifies what property should display, SelectedValuePath cannot be used.

SelectedItem, meanwhile, returns the entire Person object currently selected.

(Here's a further example from MSDN, using TreeView)

Update: As @Joe pointed out, the DisplayMemberPath property is unrelated to the Selected* properties. Its proper description follows:

Note that these values are distinct from DisplayMemberPath (which is defined on ItemsControl, not Selector), but that property has similar behavior to SelectedValuePath: in the absence of a style/template, it identifies which property of the object bound to item should be used as its string representation.

It's 2020 and chances are the API has already a promise-based version that works with await. However, some interfaces, especially event emitters will require this workaround:

// doesn't wait
let value;
someEventEmitter.once((e) => { value = e.value; });

// waits
let value = await new Promise((resolve) => {
  someEventEmitter.once('event', (e) => { resolve(e.value); });
});

In this particular case it would be:

let response = await new Promise((resolve) => {
  myAPI.exec('SomeCommand', (response) => { resolve(response); });
});

Await has been in new Node.js releases for the past 3 years (since v7.6).

Edit your php.ini file, search for soap.wsdl_cache_enabled and set the value to 0

[soap]
; Enables or disables WSDL caching feature.
; http://php.net/soap.wsdl-cache-enabled
soap.wsdl_cache_enabled=0

For JSON data, it's much easier to POST it as "application/json" content-type. If you use GET, you have to URL-encode the JSON in a parameter and it's kind of messy. Also, there is no size limit when you do POST. GET's size if very limited (4K at most).

To resolve this issue, while checking out the code from git itself, u need to give the command like below:

git checkout -b branchname origin/branchname

Here, by default we are setting the upstream branch, so you will not be facing the mentioned issue.

Yet another way this error message can occur...

If PowerShell is open in a directory other than the target file, e.g.:

If someScript.ps1 is located here: C:\SlowLearner\some_missing_path\someScript.ps1, then C:\SlowLearner>. ./someScript.ps1 wont work.

In that case, navigate to the path: cd some_missing_path then this would work:

C:\SlowLearner\some_missing_path>. ./someScript.ps1

//path to directory to scan
$directory = "../data/team/";

//get all text files with a .txt extension.
$texts = glob($directory . "*.txt");

//print each file name
foreach($texts as $text)
{
    echo $text;
}

To understand get and set, it's all related to how variables are passed between different classes.

The get method is used to obtain or retrieve a particular variable value from a class.

A set value is used to store the variables.

The whole point of the get and set is to retrieve and store the data values accordingly.

What I did in this old project was I had a User class with my get and set methods that I used in my Server class.

The User class's get set methods:

public int getuserID()
    {
        //getting the userID variable instance
        return userID;
    }
    public String getfirstName()
    {
        //getting the firstName variable instance
        return firstName;
    }
    public String getlastName()
    {
        //getting the lastName variable instance
        return lastName;
    }
    public int getage()
    {
        //getting the age variable instance
        return age;
    }

    public void setuserID(int userID)
    {
        //setting the userID variable value
        this.userID = userID;
    }
    public void setfirstName(String firstName)
    {
        //setting the firstName variable text
        this.firstName = firstName;
    }
    public void setlastName(String lastName)
    {
        //setting the lastName variable text
        this.lastName = lastName;
    }
    public void setage(int age)
    {
        //setting the age variable value
        this.age = age;
    }
}

Then this was implemented in the run() method in my Server class as follows:

//creates user object
                User use = new User(userID, firstName, lastName, age);
                //Mutator methods to set user objects
                use.setuserID(userID);
                use.setlastName(lastName);
                use.setfirstName(firstName);               
                use.setage(age); 

There is a combination of techniques which I found useful in solving this issue:

with open(file, 'r+') as fd:
    contents = fd.readlines()
    contents.insert(index, new_string)  # new_string should end in a newline
    fd.seek(0)  # readlines consumes the iterator, so we need to start over
    fd.writelines(contents)  # No need to truncate as we are increasing filesize

In our particular application, we wanted to add it after a certain string:

with open(file, 'r+') as fd:
    contents = fd.readlines()
    if match_string in contents[-1]:  # Handle last line to prevent IndexError
        contents.append(insert_string)
    else:
        for index, line in enumerate(contents):
            if match_string in line and insert_string not in contents[index + 1]:
                contents.insert(index + 1, insert_string)
                break
    fd.seek(0)
    fd.writelines(contents)

If you want it to insert the string after every instance of the match, instead of just the first, remove the else: (and properly unindent) and the break.

Note also that the and insert_string not in contents[index + 1]: prevents it from adding more than one copy after the match_string, so it's safe to run repeatedly.

My problem was also the fact that after upgrading to Vagrant 2.2.2 Apache2 was running as a web server when the guest booted. In the past I only had nginx as a web server.

vagrant ssh into the box and run the following command to disable Apache2 from starting up whenever the guest box boots:

sudo update-rc.d -f apache2 remove

Exit ssh, vagrant halt, vagrant up. Problem solved.

Anything in the public folder is accessible at the root path (/) so change your img tag to read:

<img src="/images/rss.jpg" alt="rss feed" />

If you wanted to use a rails tag, use this:

<%= image_tag("rss.jpg", :alt => "rss feed") %>

You can not use where clause with aggregate functions because where fetch records on the basis of condition, it goes into table record by record and then fetch record on the basis of condition we have give. So that time we can not where clause. While having clause works on the resultSet which we finally get after running a query.

Example query:

select empName, sum(Bonus) 
from employees 
order by empName 
having sum(Bonus) > 5000;

This will store the resultSet in a temporary memory, then having clause will perform its work. So we can easily use aggregate functions here.

In your view template, set a default value:

f.text_field :password, :value => "password"

In your Javascript (assuming jquery here):

$(document).ready(function() {
  //add a handler to remove the text
});

Just pass var2 as an extra argument to one of the apply functions.

mylist <- list(a=1,b=2,c=3)
myfxn <- function(var1,var2){
  var1*var2
}
var2 <- 2

sapply(mylist,myfxn,var2=var2)

This passes the same var2 to every call of myfxn. If instead you want each call of myfxn to get the 1st/2nd/3rd/etc. element of both mylist and var2, then you're in mapply's domain.

Update: Swift 4

In the below class setter and getter is applied to variable sideLength

class Triangle: {
    var sideLength: Double = 0.0

    init(sideLength: Double, name: String) { //initializer method
        self.sideLength = sideLength
        super.init(name: name)
        numberOfSides = 3
    }

    var perimeter: Double {
        get { // getter
            return 3.0 * sideLength
        }
        set(newValue) { //setter
            sideLength = newValue / 4.0
        }
   }

Creating object

var triangle = Triangle(sideLength: 3.9, name: "a triangle")

Getter

print(triangle.perimeter) // invoking getter

Setter

triangle.perimeter = 9.9 // invoking setter

In 2018 here is what worked for me using MacOS HighSierra:

sudo lsof -nPi :yourPortNumber

then:

sudo kill -9 yourPIDnumber

The question doesn't address multiline strings, but here is how you would strip leading whitespace from a multiline string using python's standard library textwrap module. If we had a string like:

s = """
    line 1 has 4 leading spaces
    line 2 has 4 leading spaces
    line 3 has 4 leading spaces
"""

if we print(s) we would get output like:

>>> print(s)
    this has 4 leading spaces 1
    this has 4 leading spaces 2
    this has 4 leading spaces 3

and if we used textwrap.dedent:

>>> import textwrap
>>> print(textwrap.dedent(s))
this has 4 leading spaces 1
this has 4 leading spaces 2
this has 4 leading spaces 3

You can try FileUtils#forceMkdir

FileUtils.forceMkdir("/path/directory");

This library have a lot of useful functions.

You can't do that, unless you take the child out of the parent and place it via positioning.

The only way I know and it actually works, is to use a translucid image (.png with transparency) for the parent's background. The only disavantage is that you can't control the opacity via CSS, other than that it works!

If you've already pushed things to a remote server (and you have other developers working off the same remote branch) the important thing to bear in mind is that you don't want to rewrite history

Don't use git reset --hard

You need to revert changes, otherwise any checkout that has the removed commits in its history will add them back to the remote repository the next time they push; and any other checkout will pull them in on the next pull thereafter.

If you have not pushed changes to a remote, you can use

git reset --hard <hash>

If you have pushed changes, but are sure nobody has pulled them you can use

git reset --hard
git push -f

If you have pushed changes, and someone has pulled them into their checkout you can still do it but the other team-member/checkout would need to collaborate:

(you) git reset --hard <hash>
(you) git push -f

(them) git fetch
(them) git reset --hard origin/branch

But generally speaking that's turning into a mess. So, reverting:

The commits to remove are the lastest

This is possibly the most common case, you've done something - you've pushed them out and then realized they shouldn't exist.

First you need to identify the commit to which you want to go back to, you can do that with:

git log

just look for the commit before your changes, and note the commit hash. you can limit the log to the most resent commits using the -n flag: git log -n 5

Then reset your branch to the state you want your other developers to see:

git revert  <hash of first borked commit>..HEAD

The final step is to create your own local branch reapplying your reverted changes:

git branch my-new-branch
git checkout my-new-branch
git revert <hash of each revert commit> .

Continue working in my-new-branch until you're done, then merge it in to your main development branch.

The commits to remove are intermingled with other commits

If the commits you want to revert are not all together, it's probably easiest to revert them individually. Again using git log find the commits you want to remove and then:

git revert <hash>
git revert <another hash>
..

Then, again, create your branch for continuing your work:

git branch my-new-branch
git checkout my-new-branch
git revert <hash of each revert commit> .

Then again, hack away and merge in when you're done.

You should end up with a commit history which looks like this on my-new-branch

2012-05-28 10:11 AD7six             o [my-new-branch] Revert "Revert "another mistake""
2012-05-28 10:11 AD7six             o Revert "Revert "committing a mistake""
2012-05-28 10:09 AD7six             o [master] Revert "committing a mistake"
2012-05-28 10:09 AD7six             o Revert "another mistake"
2012-05-28 10:08 AD7six             o another mistake
2012-05-28 10:08 AD7six             o committing a mistake
2012-05-28 10:05 Bob                I XYZ nearly works

Better way®

Especially that now that you're aware of the dangers of several developers working in the same branch, consider using feature branches always for your work. All that means is working in a branch until something is finished, and only then merge it to your main branch. Also consider using tools such as git-flow to automate branch creation in a consistent way.

You can simply use CSS transitions, see this fiddle

.on {
color:#fff;
transition:all 1s;
}

.off{
color:#000;
transition:all 1s;
}

You can use RelativeLayout. Let's say you wanted a 30x40 ImageView at position (50,60) inside your layout. Somewhere in your activity:

// Some existing RelativeLayout from your layout xml
RelativeLayout rl = (RelativeLayout) findViewById(R.id.my_relative_layout);

ImageView iv = new ImageView(this);

RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 50;
params.topMargin = 60;
rl.addView(iv, params);

More examples:

Places two 30x40 ImageViews (one yellow, one red) at (50,60) and (80,90), respectively:

RelativeLayout rl = (RelativeLayout) findViewById(R.id.my_relative_layout);
ImageView iv;
RelativeLayout.LayoutParams params;

iv = new ImageView(this);
iv.setBackgroundColor(Color.YELLOW);
params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 50;
params.topMargin = 60;
rl.addView(iv, params);

iv = new ImageView(this);
iv.setBackgroundColor(Color.RED);
params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 80;
params.topMargin = 90;
rl.addView(iv, params);

Places one 30x40 yellow ImageView at (50,60) and another 30x40 red ImageView <80,90> relative to the yellow ImageView:

RelativeLayout rl = (RelativeLayout) findViewById(R.id.my_relative_layout);
ImageView iv;
RelativeLayout.LayoutParams params;

int yellow_iv_id = 123; // Some arbitrary ID value.

iv = new ImageView(this);
iv.setId(yellow_iv_id);
iv.setBackgroundColor(Color.YELLOW);
params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 50;
params.topMargin = 60;
rl.addView(iv, params);

iv = new ImageView(this);
iv.setBackgroundColor(Color.RED);
params = new RelativeLayout.LayoutParams(30, 40);
params.leftMargin = 80;
params.topMargin = 90;

// This line defines how params.leftMargin and params.topMargin are interpreted.
// In this case, "<80,90>" means <80,90> to the right of the yellow ImageView.
params.addRule(RelativeLayout.RIGHT_OF, yellow_iv_id);

rl.addView(iv, params);

My English is not good so I'll just write a simple example here.

    double a = 0.02;
    double b = 0.03;
    double c = b - a;
    System.out.println(c);

    BigDecimal _a = new BigDecimal("0.02");
    BigDecimal _b = new BigDecimal("0.03");
    BigDecimal _c = _b.subtract(_a);
    System.out.println(_c);

Program output:

0.009999999999999998
0.01

Somebody still want to use double? ;)

in Mysql Doku: http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_extract

SELECT EXTRACT( YEAR_MONTH FROM `date` ) 
FROM `Table` WHERE Condition = 'Condition';

I had the same problem, I enabled "Anonymous Authentication" but it still did not work. So I also ENABLED "Forms Authentication" Then it worked without any problems.

Use JodaTime for this. It is much better than the standard Java DateTime Apis. Here is the code in JodaTime for calculating difference in days:

private static void dateDiff() {

    System.out.println("Calculate difference between two dates");
    System.out.println("=================================================================");

    DateTime startDate = new DateTime(2000, 1, 19, 0, 0, 0, 0);
    DateTime endDate = new DateTime();

    Days d = Days.daysBetween(startDate, endDate);
    int days = d.getDays();

    System.out.println("  Difference between " + endDate);
    System.out.println("  and " + startDate + " is " + days + " days.");

  }

I might be off here, but it seems that the answer is quite obvious: Look at reference paths in the project properties. In our setup I added our common repository folder, to the ref path GUI window, like so

That way I can copy my dlls (ready for publish) to this folder and every developer now gets the updated DLL every time it builds from this folder.

If the dll is found in the Solution, the builder should prioritize the local version over the published team version.

Building on @miklov-kriven's very helpful answer, I hope these two additional points of consideration prove helpful to someone:

(1) I find it a nice idea to include serializer and de-serializer as static inner classes in the same class. NB, using ThreadLocal for thread safety of SimpleDateFormat.

public class DateConverter {

    private static final ThreadLocal<SimpleDateFormat> sdf = 
        ThreadLocal.<SimpleDateFormat>withInitial(
                () -> {return new SimpleDateFormat("yyyy-MM-dd HH:mm a z");});

    public static class Serialize extends JsonSerializer<Date> {
        @Override
        public void serialize(Date value, JsonGenerator jgen SerializerProvider provider) throws Exception {
            if (value == null) {
                jgen.writeNull();
            }
            else {
                jgen.writeString(sdf.get().format(value));
            }
        }
    }

    public static class Deserialize extends JsonDeserializer<Date> {
        @Overrride
        public Date deserialize(JsonParser jp, DeserializationContext ctxt) throws Exception {
            String dateAsString = jp.getText();
            try {
                if (Strings.isNullOrEmpty(dateAsString)) {
                    return null;
                }
                else {
                    return new Date(sdf.get().parse(dateAsString).getTime());
                }
            }
            catch (ParseException pe) {
                throw new RuntimeException(pe);
            }
        }
    }
}

(2) As an alternative to using @JsonSerialize and @JsonDeserialize annotations on each individual class member you could also consider overriding Jackson's default serialization by applying the custom serialization at an application level, that is all class members of type Date will be serialized by Jackson using this custom serialization without explicit annotation on each field. If you are using Spring Boot for example one way to do this would as follows:

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public Module customModule() {
        SimpleModule module = new SimpleModule();
        module.addSerializer(Date.class, new DateConverter.Serialize());
        module.addDeserializer(Date.class, new Dateconverter.Deserialize());
        return module;
    }
}

var myNewString = myOldString.replace(/'/g, "\\'");

The solution @miki725 is absolutely correct. Alternatively, if you would like to use the args attribute as opposed to kwargs, then you can simply modify your code as follows:

project_id = 4
reverse('edit_project', args=(project_id,))

An example of this can be found in the documentation. This essentially does the same thing, but the attributes are passed as arguments. Remember that any arguments that are passed need to be assigned a value before being reversed. Just use the correct namespace, which in this case is 'edit_project'.

This post already has a checked answer, but the answer doesn't filter for null values. The correct answer should prevent null values by using the Object::nonNull function as a predicate.

BigDecimal result = invoiceList.stream()
    .map(Invoice::total)
    .filter(Objects::nonNull)
    .filter(i -> (i.getUnit_price() != null) && (i.getQuantity != null))
    .reduce(BigDecimal.ZERO, BigDecimal::add);

This prevents null values from attempting to be summed as we reduce.

Maybe you simply want the standard format string "N", as in

number.ToString("N")

It will use thousand separators, and a fixed number of fractional decimals. The symbol for thousands separators and the symbol for the decimal point depend on the format provider (typically CultureInfo) you use, as does the number of decimals (which will normally by 2, as you require).

If the format provider specifies a different number of decimals, and if you don't want to change the format provider, you can give the number of decimals after the N, as in .ToString("N2").

Edit: The sizes of the groups between the commas are governed by the

CultureInfo.CurrentCulture.NumberFormat.NumberGroupSizes

array, given that you don't specify a special format provider.

Just Taking Input

the_input = raw_input("Enter input: ")

And that's it.

Moreover, if you want to make a list of inputs, you can do something like:

a = []

for x in xrange(1,10):
    a.append(raw_input("Enter Data: "))

In that case, you'll be asked for data 10 times to store 9 items in a list.

Output:

Enter data: 2
Enter data: 3
Enter data: 4
Enter data: 5
Enter data: 7
Enter data: 3
Enter data: 8
Enter data: 22
Enter data: 5
>>> a
['2', '3', '4', '5', '7', '3', '8', '22', '5']

You can search that list the fundamental way with something like (after making that list):

if '2' in a:
    print "Found"

else: print "Not found."

You can replace '2' with "raw_input()" like this:

if raw_input("Search for: ") in a:
    print "Found"
else: 
    print "Not found"

Taking Raw Data From Input File via Commandline Interface

If you want to take the input from a file you feed through commandline (which is normally what you need when doing code problems for competitions, like Google Code Jam or the ACM/IBM ICPC):

example.py

while(True):
    line = raw_input()
    print "input data: %s" % line

In command line interface:

example.py < input.txt

Hope that helps.

Use array_unshift() to insert the first element in an array.

User array_shift() to removes the first element of an array.

Yes, they can throw exceptions. If so, they will only be partially initialized and if non-final, subject to attack.

The following is from the Secure Coding Guidelines 2.0.

Partially initialized instances of a non-final class can be accessed via a finalizer attack. The attacker overrides the protected finalize method in a subclass, and attempts to create a new instance of that subclass. This attempt fails (in the above example, the SecurityManager check in ClassLoader's constructor throws a security exception), but the attacker simply ignores any exception and waits for the virtual machine to perform finalization on the partially initialized object. When that occurs the malicious finalize method implementation is invoked, giving the attacker access to this, a reference to the object being finalized. Although the object is only partially initialized, the attacker can still invoke methods on it (thereby circumventing the SecurityManager check).

To run the spring-boot application, need to follow some step.

1. Maven setup (ignore if already setup):

   a. Install maven from https://maven.apache.org/download.cgi

   b. Unzip maven and keep in C drive (you can keep any location. Path location will be changed accordingly).

   c. Set MAVEN_HOME in system variable.

   d. Set path for maven

2. Add Maven Plugin to POM.XML

   <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build>

3. Build Spring Boot Project with Maven

      maven package
   

   or

        mvn install / mvn clean install
   

4. Run Spring Boot app using Maven:

       mvn spring-boot:run
   

5. [optional] Run Spring Boot app with java -jar command

        java -jar target/mywebserviceapp-0.0.1-SNAPSHOT.jar
   

Mind you that in my experience and also of other (PHP - Why is new SQLSRV driver slower than the old mssql driver?) that using PDO_SQLSRV is way slower than through PDO_ODBC.

If you want to use the faster PDO_ODBC you can use:

//use any of these or check exact MSSQL ODBC drivername in "ODBC Data Source Administrator"
$mssqldriver = '{SQL Server}'; 
$mssqldriver = '{SQL Server Native Client 11.0}';
$mssqldriver = '{ODBC Driver 11 for SQL Server}';

$hostname='127.0.0.1';
$dbname='test';
$username='user';
$password='pw';
$dbDB = new PDO("odbc:Driver=$mssqldriver;Server=$hostname;Database=$dbname", $username, $password);

you can use below function if you know the id of the user:

function getUser(id){
var returnValue;
jQuery.ajax({
 url: "http://YourSite/_api/Web/GetUserById(" + id + ")",
 type: "GET",
 headers: { "Accept": "application/json;odata=verbose" },
 success: function(data) {
       var dataResults = data.d;
       alert(dataResults.Title);
  }
});
}

or you can try

var listURL = _spPageContextInfo.webAbsoluteUrl + "/_api/web/currentuser";

The windows handle limit for your application is 10,000 handles. You're getting the error because your program is creating too many handles. You'll need to find the memory leak. As other users have suggested, use a Memory Profiler. I use the .Net Memory Profiler as well. Also, make sure you're calling the dispose method on controls if you're removing them from a form before the form closes (otherwise the controls won't dispose). You'll also have to make sure that there are no events registered with the control. I myself have the same issue, and despite what I already know, I still have some memory leaks that continue to elude me..

First try this code inside AndroidManifest

  <application>
       
    <uses-library
        android:name="org.apache.http.legacy"
        android:required="false" />
 </application>

If this code works, so fine. But if not. Try this code from which class you want to pass the data or uri.

Intent window = new Intent(getApplicationContext(), Browser.class);
window.putExtra("LINK", "http://www.yourwebsite.com");
startActivity(window);

for me it only worked with !important in css

.datepicker {z-index: 1151 !important;}
