String filePath = folder.getAbsolutePath()+ "/logcat.txt"; 
Runtime.getRuntime().exec(new String[]{"logcat", "-f", filePath, "MyAppTAG:V", "*:E"});

put this to applog.sh

#!/bin/sh
PACKAGE=$1
APPPID=`adb -d shell ps | grep "${PACKAGE}" | cut -c10-15 | sed -e 's/ //g'`
adb -d logcat -v long \

 | grep " ${APPPID}:"

then: applog.sh com.example.my.package

Choreographer lets apps to connect themselves to the vsync, and properly time things to improve performance.

Android view animations internally uses Choreographer for the same purpose: to properly time the animations and possibly improve performance.

Since Choreographer is told about every vsync events, it can tell if one of the Runnables passed along by the Choreographer.post* apis doesn't finish in one frame's time, causing frames to be skipped.

In my understanding Choreographer can only detect the frame skipping. It has no way of telling why this happens.

The message "The application may be doing too much work on its main thread." could be misleading.

This happened to me because I enabled usb debug previously on another pc. So to mke it work on a second pc I had to disable usb debugging and re-enable it while connected to the second pc and it worked.

In Android Studio 3.4, In the case in which Logcat does not appear in View->ToolWindows->Logcat (in that case Alt+6 or CMD+6 will also not work), the way to get the logact window is:

1. File->Profile or debug APK (choose an APK)
2. Select new window or use current window.
3. Logcat is now available through the menu (View->ToolWindows->Logcat) or through Alt+6 or CMD+6

This issue is an indication that something is not configured correctly with the Android Studio project. The above solution can be useful:

1. As a temporary solution when there are configuration issues with the Android Studio project, that for some reason are causing Android Studio to hide the logcat window.
2. When trying to use the Android Studio logcat window for debugging an app without an Android Studio project.

I had a problem seeing simple log output in logcat as well. My problem was solved when I installed the latest JDK. I just setup a new development machine and only had the JRE installed and instaling the JDK worked for me.

Do not depend on ADB shell, just treat it (the adb logcat) a normal linux output and then pip it:

$ adb shell logcat | grep YouTag
# just like: 
$ ps -ef | grep your_proc 

You can get current Playstore Version using JSoup with some modification like below:

@Override
protected String doInBackground(Void... voids) {

    String newVersion = null;
    try {
        newVersion = Jsoup.connect("https://play.google.com/store/apps/details?id=" + MainActivity.this.getPackageName() + "&hl=it")
                .timeout(30000)
                .userAgent("Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-US; rv1.8.1.6) Gecko/20070725 Firefox/2.0.0.6")
                .referrer("http://www.google.com")
                .get()
                .select(".hAyfc .htlgb")
                .get(7)
                .ownText();
        return newVersion;
    } catch (Exception e) {
        return newVersion;
    }
}

@Override
protected void onPostExecute(String onlineVersion) {
    super.onPostExecute(onlineVersion);

    Log.d("update", "playstore version " + onlineVersion);
}

answer of @Tarun is not working anymore.

Its advantages are that it simplifies the usage of WebSockets as you described in #2, and probably more importantly it provides fail-overs to other protocols in the event that WebSockets are not supported on the browser or server. I would avoid using WebSockets directly unless you are very familiar with what environments they don't work and you are capable of working around those limitations.

This is a good read on both WebSockets and Socket.IO.

Maybe you can try to use the function gc(). A call of gc() causes a garbage collection to take place. It can be useful to call gc() after a large object has been removed, as this may prompt R to return memory to the operating system. gc() also return a summary of the occupy memory.

These have the same end result, but I would simply add that using the literal syntax can help one become accustomed to the syntax of JSON (a string-ified subset of JavaScript literal object syntax), so it might be a good practice to get into.

One other thing: you might have subtle errors if you forget to use the new operator. So, using literals will help you avoid that problem.

Ultimately, it will depend on the situation as well as preference.

I read the answer by Sjeiti which I found very interesting, where you with just a few plain JavaScript lines can render HTML in an image.

We of course have to be aware of the limitations of this method (please read about some of them in his answer).

Here I have taken his code a couple of steps further.

An SVG-image has in principle infinite resolution, since it is vector graphics. But you might have noticed that the image that Sjeiti's code generated did not have a high resolution. This can be fixed by scaling the SVG-image before transferring it to the canvas-element, which I have done in the last one of the two (runnable) example codes i give below. The other thing I have implemented in that code is the last step, namely saving it as a PNG-file. Just to complete the whole thing.

So, I give two runnable snippets of code:

The first one demonstrates the infinite resolution of an SVG. Run it and zoom in with your browser to see that the resolution does not diminish as you zoom in.

In the snippet that you can run I have used backticks to specify a so called template string with line breaks so that you can more clearly see the HTML that is rendered. But otherwise, if that HTML is within one line, then the code will be very short, like this.

const body = document.getElementsByTagName('BODY')[0];
const img = document.createElement('img')
img.src = 'data:image/svg+xml,' + encodeURIComponent(`<svg xmlns="http://www.w3.org/2000/svg" width="200" height="200"><foreignObject width="100%" height="100%"><div xmlns="http://www.w3.org/1999/xhtml" style="border:1px solid red;padding:20px;"><style>em {color:red;}.test {color:blue;}</style>What you see here is only an image, nothing else.<br /><br /><em>I</em> really like <span class="test">cheese.</span><br /><br />Zoom in to check the resolution!</div></foreignObject></svg>`);        
body.appendChild(img);

Here it comes as a runnable snippet.

const body = document.getElementsByTagName('BODY')[0];
const img = document.createElement('img')
img.src = 'data:image/svg+xml,' + encodeURIComponent(`
  <svg xmlns="http://www.w3.org/2000/svg" width="200" height="200">
    <foreignObject width="100%" height="100%">
      <div xmlns="http://www.w3.org/1999/xhtml" style="border:1px solid red;padding:20px;">
        <style>
          em {
            color:red;
          }
          .test {
            color:blue;
          }
        </style>
        What you see here is only an image, nothing
        else.<br />
        <br />
        <em>I</em> really like <span class="test">cheese.</span><br />
        <br />
        Zoom in to check the resolution!
      </div>
    </foreignObject>
  </svg>
`);
body.appendChild(img);

Zoom in and check the infinite resolution of the SVG.

The next runnable, below, is the one that implements the two extra steps which I mentioned above, namely improving resolution by first scaling the SVG, and then the saving as a PNG-image.

window.addEventListener("load", doit, false)
var canvas;
var ctx;
var tempImg;
function doit() {
    const body = document.getElementsByTagName('BODY')[0];
    const scale = document.getElementById('scale').value;
    let trans = document.getElementById('trans').checked;
  if (trans) {
    trans = '';
  } else {
    trans = 'background-color:white;';
  }
    let source = `
        <div xmlns="http://www.w3.org/1999/xhtml" style="border:1px solid red;padding:20px;${trans}">
            <style>
                em {
                    color:red;
                }
                .test {
                    color:blue;
                }
            </style>
            What you see here is only an image, nothing
            else.<br />
            <br />
            <em>I</em> really like <span class="test">cheese.</span><br />
            <br />
            <div style="text-align:center;">
                Scaling:

                ${scale} times!
            </div>
        </div>`
    document.getElementById('source').innerHTML = source;
    canvas = document.createElement('canvas');
    ctx = canvas.getContext('2d');
    canvas.width = 200*scale;
    canvas.height = 200*scale;
    tempImg = document.createElement('img');
    tempImg.src = 'data:image/svg+xml,' + encodeURIComponent(`
        <svg xmlns="http://www.w3.org/2000/svg" width="${200*scale}" height="${200*scale}">

    `);
}
function saveAsPng(){
    ctx.drawImage(tempImg, 0, 0);
    var a  = document.createElement('a');
    a.href = canvas.toDataURL('image/png');
    a.download = 'image.png';
    a.click();
}

                &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;To increase the resolution of the image you can change the scaling with this slider.
                <div style="text-align:right;margin:5px 0px;">

            </div>
            
        </td>
    </tr>

Try with different scalings. If you for example set scaling to 10, then you get a very good resolution in the generated PNG-image. And I added a little extra feature: a checkbox so that you can make the PNG-image transparent if you like.

Notice:

The Save-button does not work in Chrome and Edge when this script is run here at Stack Overflow. The reason is this https://www.chromestatus.com/feature/5706745674465280 .

Therefore I have also put this snippet on https://jsfiddle.net/7gozdq5v/ where it works for those browsers.

Of course there IS a way to create files without opening. It's as easy as calling os.mknod("newfile.txt"). The only drawback is that this call requires root privileges on OSX.

If you are using Swift, this will do the same:

buttonName.setTitleColor(UIColor.blackColor(), forState: .Normal)

Hope that helps!

What about having a live validation on the textbox, and once it goes over 2000 (or whatever the maximum threshold is) then display 'This email is too long to be completed in the browser, please <span class="launchEmailClientLink">launch what you have in your email client</span>'

To which I'd have

.launchEmailClientLink {
cursor: pointer;
color: #00F;
}

and jQuery this into your onDomReady

$('.launchEmailClientLink').bind('click',sendMail);

I had the same issue, and found a solution. Try this: %0D%0A to add a line break.

int main()
{
  int size;

  std::cin >> size;

  int *array = new int[size];

  delete [] array;

  return 0;
}

Don't forget to delete every array you allocate with new.

The bind() method creates a new function instance whose this value is bound to the value that was passed into bind(). For example:

   window.color = "red"; 
   var o = { color: "blue" }; 
   function sayColor(){ 
       alert(this.color); 
   } 
   var objectSayColor = sayColor.bind(o); 
   objectSayColor(); //blue 

Here, a new function called objectSayColor() is created from sayColor() by calling bind() and passing in the object o. The objectSayColor() function has a this value equivalent to o, so calling the function, even as a global call, results in the string “blue” being displayed.

I had the exact same problem — fix was babel-preset-react-native-stage-0, instead of babel-preset-react-native.

I don't have enough rep to answer ClintEastwood, and the accepted answer is correct for the Web.config file. Adding this in for code difference.

When your mailSettings are set on Web.config, you don't need to do anything other than new up your SmtpClient and .Send. It finds the connection itself without needing to be referenced. You would change your C# from this:

SmtpClient smtpClient = new SmtpClient("smtp.sender.you", Convert.ToInt32(587));
System.Net.NetworkCredential credentials = new System.Net.NetworkCredential("username", "password");
smtpClient.Credentials = credentials;
smtpClient.Send(msgMail);  

To this:

SmtpClient smtpClient = new SmtpClient();
smtpClient.Send(msgMail);

Use:

$filelist = @(11, 1, 2)
$filelist | sort @{expression={$_[0]}} | 
  % {$newName = [string]([int]$($_[0]) + 1)}
  New-Item $newName -ItemType Directory

Best way is,

SELECT to_number(replace(:Str,',','')/100) --into num2 
FROM dual;

Rhomobile Rhodes (http://rhomobile.com/products/rhodes) is very similar in approach to PhoneGap, but is the only framework with:

1. a Model View Controller pattern (as most web frameworks provide)
2. an Object Relational Manager
3. support for all popular smartphones (including Windows Phone 7)
4. a hosted development service (not just hosted build): http://rhohub.com
5. a full debugger and SDK-less emulator in the RhoStudio IDE
6. support for synchronized offline data

If you look into CREATE PROCEDURE Syntax for latest MySQL version you'll see that procedure parameter can only contain IN/OUT/INOUT specifier, parameter name and type.

So, default values are still unavailable in latest MySQL version.

in my case, internet on emulator is down as there is no wifi signal on emulator. Resetting emulator has worked.

TextBlock does not have a template. So inorder to achieve this, we need to use a TextBox whose style is changed to behave as a textBlock.

<Style x:Key="TextBlockUsingTextBoxStyle" BasedOn="{x:Null}" TargetType="{x:Type TextBox}">
    <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="BorderBrush" Value="{StaticResource TextBoxBorder}"/>
    <Setter Property="BorderThickness" Value="0"/>
    <Setter Property="Padding" Value="1"/>
    <Setter Property="AllowDrop" Value="true"/>
    <Setter Property="FocusVisualStyle" Value="{x:Null}"/>
    <Setter Property="ScrollViewer.PanningMode" Value="VerticalFirst"/>
    <Setter Property="Stylus.IsFlicksEnabled" Value="False"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type TextBox}">
                <TextBox BorderThickness="{TemplateBinding BorderThickness}" IsReadOnly="True" Text="{TemplateBinding Text}" Background="{x:Null}" BorderBrush="{x:Null}" />
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Because you need parentheses around the value your looking for. So here : document.querySelector('a[data-a="1"]')

If you don't know in advance the value but is looking for it via variable you can use template literals :

Say we have divs with data-price

<div data-price="99">My okay price</div>
<div data-price="100">My too expensive price</div>

We want to find an element but with the number that someone chose (so we don't know it):

// User chose 99    
let chosenNumber = 99
document.querySelector(`[data-price="${chosenNumber}"`]

You have multiple options. Two options are the following.

numpy.sum(boolarr)
numpy.count_nonzero(boolarr)

Here's an example:

>>> import numpy as np
>>> boolarr = np.array([[0, 0, 1], [1, 0, 1], [1, 0, 1]], dtype=np.bool)
>>> boolarr
array([[False, False,  True],
       [ True, False,  True],
       [ True, False,  True]], dtype=bool)

>>> np.sum(boolarr)
5

Of course, that is a bool-specific answer. More generally, you can use numpy.count_nonzero.

>>> np.count_nonzero(boolarr)
5

It looks like what you want to do is remove your first merge. You could follow the following procedure:

git checkout master      # Let's make sure we are on master branch
git reset --hard master~ # Let's get back to master before the merge
git pull                 # or git merge remote/master
git merge topic

That would give you what you want.

I suppose that 255 in 227./255 is perceived as an integer and divide is always return 0

Some few things you must take care if you assign a reference to a new object to exports and /or modules.exports:

1. All properties/methods previously attached to the original exports or module.exports are of course lost because the exported object will now reference another new one

This one is obvious, but if you add an exported method at the beginning of an existing module, be sure the native exported object is not referencing another object at the end

exports.method1 = function () {}; // exposed to the original exported object
exports.method2 = function () {}; // exposed to the original exported object

module.exports.method3 = function () {}; // exposed with method1 & method2

var otherAPI = {
    // some properties and/or methods
}

exports = otherAPI; // replace the original API (works also with module.exports)

2. In case one of exports or module.exports reference a new value, they don't reference to the same object any more

exports = function AConstructor() {}; // override the original exported object
exports.method2 = function () {}; // exposed to the new exported object

// method added to the original exports object which not exposed any more
module.exports.method3 = function () {}; 

3. Tricky consequence. If you change the reference to both exports and module.exports, hard to say which API is exposed (it looks like module.exports wins)

// override the original exported object
module.exports = function AConstructor() {};

// try to override the original exported object
// but module.exports will be exposed instead
exports = function AnotherConstructor() {}; 

To get the bottom 1000 you will want to order it by a column in descending order, and still take the top 1000.

SELECT TOP 1000 *
FROM [SomeTable]
ORDER BY MySortColumn DESC

If you care for it to be in the same order as before you can use a common table expression for that:

;WITH CTE AS (
    SELECT TOP 1000 *
    FROM [SomeTable]
    ORDER BY MySortColumn DESC
)

SELECT * 
FROM CTE
ORDER BY MySortColumn

//ICO , DI ,10 years back , this was they way:

public class  AuditDAOImpl implements Audit{

    //dependency
    AuditDAO auditDAO = null;
        //Control of the AuditDAO is with AuditDAOImpl because its creating the object
    public AuditDAOImpl () {
        this.auditDAO = new AuditDAO ();
    }
}

Now with Spring 3,4 or latest its like below

public class  AuditDAOImpl implements Audit{

    //dependency

     //Now control is shifted to Spring. Container find the object and provide it. 
    @Autowired
    AuditDAO auditDAO = null;

}

Overall the control is inverted from old concept of coupled code to the frameworks like Spring which makes the object available. So that's IOC as far as I know and Dependency injection as you know when we inject the dependent object into another object using Constructor or setters . Inject basically means passing it as an argument. In spring we have XML & annotation based configuration where we define bean object and pass the dependent object with Constructor or setter injection style.

you can use JsonConvert.SerializeObject()

JsonConvert.SerializeObject(myObject) // myObject is returned by JObject.Parse() method

JsonConvert.SerializeObject()

JObject.Parse()

It hides the intention of the code.

It's two single tilde operators, so it does a bitwise complement (bitwise not) twice. The operations take out each other, so the only remaining effect is the conversion that is done before the first operator is applied, i.e. converting the value to an integer number.

Some use it as a faster alternative to Math.floor, but the speed difference is not that dramatic, and in most cases it's just micro optimisation. Unless you have a piece of code that really needs to be optimised, you should use code that descibes what it does instead of code that uses a side effect of a non-operation.

Update 2011-08:

With optimisation of the JavaScript engine in browsers, the performance for operators and functions change. With current browsers, using ~~ instead of Math.floor is somewhat faster in some browsers, and not faster at all in some browsers. If you really need that extra bit of performance, you would need to write different optimised code for each browser.

See: tilde vs floor

Division is performed using the / operator:

result = a / b;

Modulo division is done using the % operator:

result = a % b;

You can use the sort keyword like this:

sort(unique(c))[1:N]

Example:

c <- c(4,2,44,2,1,45,34,2,4,22,244)
sort(unique(c), decreasing = TRUE)[1:5]

will give the first 5 max numbers.

Following is one liner for accepted answer ... (for one line lovers ..)

def search_dict(my_dict,searchFor):
    s_val = [[ k if searchFor in v else None for v in my_dict[k]] for k in my_dict]    
    return s_val

You can find the answer on this other S.O. question:

MySQL - can I limit the maximum time allowed for a query to run?

a cron job that runs every second on your database server, connecting and doing something like this:

• SHOW PROCESSLIST
• Find all connections with a query time larger than your maximum desired time
• Run KILL [process id] for each of those processes

You can use the below code for it.

[[UIApplication sharedApplication]openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];

Best way to do is use the extension(pflannery.vscode-versionlens) in vscode.

this checks for all satisfy and checks for best fit.

i had lot of issues with updating and keeping my app functioining unitll i let verbose lense did the check and then i run

npm i

to install newly suggested dependencies.

I think that what you want to do is turn the JSON string back into an object when it arrives back in your XMLHttpRequest - correct?

If so, you need to eval the string to turn it into a JavaScript object - note that this can be unsafe as you're trusting that the JSON string isn't malicious and therefore executing it. Preferably you could use jQuery's parseJSON

You should use TEXT (storing unlimited number of characters) for the sake of forward compatibility. Hashing algorithms (need to) become stronger over time and thus this database field will need to support more characters over time. Additionally depending on your migration strategy you may need to store new and old hashes in the same field, so fixing the length to one type of hash is not recommended.

Your printf needs a format string:

printf("%d\n", x);

This reference page gives details on how to use printf and related functions.

This is because the shell script is formatted in windows we need to change to unix format. You can run the dos2unix command on any Linux system.

dos2unix your-file.sh

If you don’t have access to a Linux system, you may use the Git Bash for Windows which comes with a dos2unix.exe

dos2unix.exe your-file.sh 

Daemon threads are like a service providers for other threads or objects running in the same process as the daemon thread. Daemon threads are used for background supporting tasks and are only needed while normal threads are executing. If normal threads are not running and remaining threads are daemon threads then the interpreter exits.

For example, the HotJava browser uses up to four daemon threads named "Image Fetcher" to fetch images from the file system or network for any thread that needs one.

Daemon threads are typically used to perform services for your application/applet (such as loading the "fiddley bits"). The core difference between user threads and daemon threads is that the JVM will only shut down a program when all user threads have terminated. Daemon threads are terminated by the JVM when there are no longer any user threads running, including the main thread of execution.

setDaemon(true/false) ? This method is used to specify that a thread is daemon thread.

public boolean isDaemon() ? This method is used to determine the thread is daemon thread or not.

Eg:

public class DaemonThread extends Thread {
    public void run() {
        System.out.println("Entering run method");

        try {
            System.out.println("In run Method: currentThread() is" + Thread.currentThread());

            while (true) {
                try {
                    Thread.sleep(500);
                } catch (InterruptedException x) {}

                System.out.println("In run method: woke up again");
            }
        } finally {
            System.out.println("Leaving run Method");
        }
    }
    public static void main(String[] args) {
        System.out.println("Entering main Method");

        DaemonThread t = new DaemonThread();
        t.setDaemon(true);
        t.start();

        try {
            Thread.sleep(3000);
        } catch (InterruptedException x) {}

        System.out.println("Leaving main method");
    }

}

OutPut:

C:\java\thread>javac DaemonThread.java

A dialect is a form of the language that is spoken by a particular group of people.

Here, in context of hibernate framework, When hibernate wants to talk(using queries) with the database it uses dialects.

The SQL dialect's are derived from the Structured Query Language which uses human-readable expressions to define query statements.
A hibernate dialect gives information to the framework of how to convert hibernate queries(HQL) into native SQL queries.

The dialect of hibernate can be configured using below property:

hibernate.dialect

Here, is a complete list of hibernate dialects.

Note: The dialect property of hibernate is not mandatory.

You need Ajax to make it happen. Something like this:

$(document).ready(function(){
    $("#myform").on('submit', function(){
        var name = $("#name").val();
        var email = $("#email").val();
        var password = $("#password").val();
        var contact = $("#contact").val();

        var dataString = 'name1=' + name + '&email1=' + email + '&password1=' + password + '&contact1=' + contact;
        if(name=='' || email=='' || password=='' || contact=='')
        {
            alert("Please fill in all fields");
        }
        else
        {
            // Ajax code to submit form.
            $.ajax({
                type: "POST",
                url: "ajaxsubmit.php",
                data: dataString,
                cache: false,
                success: function(result){
                    alert(result);
                }
           });
        }
        return false;
    });
});

you can simply hide your text by add this attribute:

font-size: 0 !important;

I want to change the width and height of a div. data attributes did not change it. Instead I use:

var size = $("#theme_photo_size").val().split("x");
$("#imageupload_img").width(size[0]);
$("#imageupload_img").attr("data-width", size[0]);
$("#imageupload_img").height(size[1]);
$("#imageupload_img").attr("data-height", size[1]);

be careful:

$("#imageupload_img").data("height", size[1]); //did not work

did not set it

$("#imageupload_img").attr("data-height", size[1]); // yes it worked!

this has set it.

I had a similar issue but my schema had a backslash in it. In this case, include the brackets around the schema.

ALTER SCHEMA dbo TRANSFER [DOMAIN\jonathan].MovieData;

One of Androids powerful feature is the AsyncTask class.

To work with it, you have to first extend it and override doInBackground(...). doInBackground automatically executes on a worker thread, and you can add some listeners on the UI Thread to get notified about status update, those functions are called: onPreExecute(), onPostExecute() and onProgressUpdate()

You can find a example here.

Refer to below post for other alternatives:

Handler vs AsyncTask vs Thread

Be sure the font is the same for all browsers. If it is the same font, then the problem has no solution using cross-browser CSS.

Because every browser has its own font rendering engine, they are all different. They can also differ in later versions, or across different OS's.

UPDATE: For those who do not understand the browser and OS font rendering differences, read this and this.

However, the difference is not even noticeable by most people, and users accept that. Forget pixel-perfect cross-browser design, unless you are:

1. Trying to turn-off the subpixel rendering by CSS (not all browsers allow that and the text may be ugly...)
2. Using images (resources are demanding and hard to maintain)
3. Replacing Flash (need some programming and doesn't work on iOS)

UPDATE: I checked the example page. Tuning the kerning by text-rendering should help:

text-rendering: optimizeLegibility; 

More references here:

1. Part of the font-rendering is controlled by font-smoothing (as mentioned) and another part is text-rendering. Tuning these properties may help as their default values are not the same across browsers.
2. For Chrome, if this is still not displaying OK for you, try this text-shadow hack. It should improve your Chrome font rendering, especially in Windows. However, text-shadow will go mad under Windows XP. Be careful.

For a non-regular expression approach, you can check Character.isWhitespace for each character.

boolean containsWhitespace(String s) {
    for (int i = 0; i < s.length(); ++i) {
        if (Character.isWhitespace(s.charAt(i)) {
            return true;
        }
    }
    return false;
}

Which are the white spaces in Java?

The documentation specifies what Java considers to be whitespace:

public static boolean isWhitespace(char ch)

Determines if the specified character is white space according to Java. A character is a Java whitespace character if and only if it satisfies one of the following criteria:

• It is a Unicode space character (SPACE_SEPARATOR, LINE_SEPARATOR, or PARAGRAPH_SEPARATOR) but is not also a non-breaking space ('\u00A0', '\u2007', '\u202F').
• It is '\u0009', HORIZONTAL TABULATION.
• It is '\u000A', LINE FEED.
• It is '\u000B', VERTICAL TABULATION.
• It is '\u000C', FORM FEED.
• It is '\u000D', CARRIAGE RETURN.
• It is '\u001C', FILE SEPARATOR.
• It is '\u001D', GROUP SEPARATOR.
• It is '\u001E', RECORD SEPARATOR.
• It is '\u001F', UNIT SEPARATOR.

In classic sh, you have to do something like:

s=test1
s="${s}test2"

(there are lots of variations on that theme, like s="$s""test2")

In bash, you can use +=:

s=test1
s+=test2

You can not directly send an email with a HTML form. You can however send the form to your web server and then generate the email with a server side program written in e.g. PHP.

The other solution is to create a link as you did with the "mailto:". This will open the local email program from the user. And he/she can then send the pre-populated email.

When you decided how you wanted to do it you can ask another (more specific) question on this site. (Or you can search for a solution somewhere on the internet.)

In my opinion the easiest and fastest way to get a Google Drive file ID is from Google Drive on the web. Right-click the file name and select Get shareable link. The last part of the link is the file ID. Then you can cancel the sharing.

--save-dev means "needed only when developing"

• e.g. the final users using your package will not want/need/care about what testing suite you used; they will only want packages that are absolutely required to run your code in a production environment. This flag marks what is needed when developing vs production.

1. goto your elastic beanstalk service tab
2. on your application overview goto action --> edit configuration
3. add the name of a key as it appears in your EC2 tab (for the same region) to the existing keypair box and hit apply changes

The service will be relaunched so make a coffee for 5 mins

On your ec2 tab for the same region you'll see your new running instance. ssh to the public dns name as ec2-user using the key added in 3 e.g. ssh [email protected]

// He had multiple haystacks
$haystackOne = range(1, 10);

$haystackThree = range(21, 30);

// In one of these haystacks he lost a needle
$needle = rand(1, 30);

// He wanted to know in what haystack his needle was
// And so he programmed...
if (in_array($needle, $haystackOne)) {
    echo "The needle is in haystack one";
} elseif (in_array($needle, $haystackTwo)) {
    echo "The needle is in haystack two";
} elseif (in_array($needle, $haystackThree)) {
    echo "The needle is in haystack three";
}

// The farmer now knew where to find his needle
// And he lived happily ever after

Only the file list (not even commit message):

E.g. open all changed files in your editor:

git show --name-only --pretty=format: | xargs "$EDITOR"

PDF2SVG version 6.0 from PDFTron does a reasonable job. It produces OpenType (.otf) fonts by default. Use --preserve_fontnames to preserve "the font/font-family naming scheme as obtained from the source file."

PDF2SVG is a commercial product, but you can download a free demo executable (which includes watermarks on the SVG output but doesn't otherwise restrict usage). There may be other PDFTron products that also extract fonts, but I only recently discovered PDF2SVG myself.

Your way is correct, and here is another way you can do it:

update      Table1
set         Description = t2.Description
from        Table1 t1
inner join  Table2 t2
on          t1.DescriptionID = t2.ID

The nested select is the long way of just doing a join.

Yes, this is confusing...

According to this blog post, it looks like this is an omission from WPF.

To make it work you need to use a style:

    <Border Name="ClearButtonBorder" Grid.Column="1" CornerRadius="0,3,3,0">
        <Border.Style>
            <Style>
                <Setter Property="Border.Background" Value="Blue"/>
                <Style.Triggers>
                    <Trigger Property="Border.IsMouseOver" Value="True">
                        <Setter Property="Border.Background" Value="Green" />
                    </Trigger>
                </Style.Triggers>
            </Style>
        </Border.Style>
        <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="X" />
    </Border>

I guess this problem isn't that common as most people tend to factor out this sort of thing into a style, so it can be used on multiple controls.

    switch(this.dealer) {
        case 1:
        case 2:
        case 3:
        case 4:
            // Do something.
            break;
        case 5:
        case 6:
        case 7:
        case 8:
            // Do something.
            break;
        default:
            break;
    }

If you don't like the succession of cases, simply go for if/else if/else statements.

Try the commons collections API:

List<Cat> bigList = ....; // master list

Collection<Cat> smallList = CollectionUtils.select(bigList, new Predicate() {
    public boolean evaluate(Object o) {
        Cat c = (Cat)o;
        return c.getFavoriteFood().equals("Wiskas") 
            && c.getWhateverElse().equals(Something);
    }
});

Of course you don't have to use an anonymous class every time, you could create implementations of the Predicate interface for commonly used searchs.

The imshow() function with parameters interpolation='nearest' and cmap='hot' should do what you want.

import matplotlib.pyplot as plt
import numpy as np

a = np.random.random((16, 16))
plt.imshow(a, cmap='hot', interpolation='nearest')
plt.show()

Another way to do it simpler using jquery.

sample:

function add(product_id){

    // the code to add the product
    //updating the div, here I just change the text inside the div. 
    //You can do anything with jquery, like change style, border etc.
    $("#added_"+product_id).html('the product was added to list');

}

Where product_id is the javascript var and$("#added_"+product_id) is a div id concatenated with product_id, the var from function add.

Best Regards!

EDIT: (As per the comments in question:)

I've been looking into this since then. I was lucky enough that I had repo laying around. Still it's not clear to me whether you need to enclose your commands between single quotes by force. I looked into the repo syntax and I don't think you need to. You could used double quotes around your command, and then use whatever single and double quotes you need inside provided you escape double ones.

The default value of the argument must be a constant expression. It can't be a variable or a function call.

If you need this functionality however:

function foo($foo, $bar = false)
{
    if(!$bar)
    {
        $bar = $foo;
    }
}

Assuming $bar isn't expected to be a boolean of course.

I've slightly modified Peter's answer here to create a reusable, non-interactive shell script called git-split.sh:

#!/bin/sh

if [[ $# -ne 2 ]] ; then
  echo "Usage: git-split.sh original copy"
  exit 0
fi

git mv "$1" "$2"
git commit -n -m "Split history $1 to $2 - rename file to target-name"
REV=`git rev-parse HEAD`
git reset --hard HEAD^
git mv "$1" temp
git commit -n -m "Split history $1 to $2 - rename source-file to temp"
git merge $REV
git commit -a -n -m "Split history $1 to $2 - resolve conflict and keep both files"
git mv temp "$1"
git commit -n -m "Split history $1 to $2 - restore name of source-file"

Replace

dateTime.setText(app.getTotalDl());

With

dateTime.setText(""+app.getTotalDl());

Use

=LEFT(B2, 2)*3600000 + MID(B2,4,2) * 60000 + MID(B2,7,2)*1000 + RIGHT(B2,3)

Use element.innerHTML="some \\\\n some";.

In addition to the rest, there's currently a draft (stage-2 proposal) on ECMA Proposals that introduces static public fields in classes. (private fields were considered)

Using the example from the proposal, the proposed static syntax will look like this:

class CustomDate {
  // ...
  static epoch = new CustomDate(0);
}

and be equivalent to the following which others have highlighted:

class CustomDate {
  // ...
}
CustomDate.epoch = new CustomDate(0);

You can then access it via CustomDate.epoch.

You can keep track of the new proposal in proposal-static-class-features.

Currently, babel supports this feature with the transform class properties plugin which you can use. Additionally, though still in progress, V8 is implementing it.

Modulus - Divides left hand operand by right hand operand and returns remainder

a = 10 and b = 20

b % a = 0

I was playing around with this and tried all solutions, eventually the solution I went with was a suggestion from Google Chrome's Inspector. If you add this to your CSS it worked for me:

video{
   object-fit: inherit;
}

Try using http://www.example.org?candy_name=M%26M.

If you want to get the index of the selected radio button inside a control you can use this method:

public static int getCheckedRadioButton(Control c)
{
    int i;
    try
    {
        Control.ControlCollection cc = c.Controls;
        for (i = 0; i < cc.Count; i++)
        {
            RadioButton rb = cc[i] as RadioButton;
            if (rb.Checked)
            {
                return i;
            }
        }
    }
    catch
    {
        i = -1;
    }
    return i;
}

Example use:

int index = getCheckedRadioButton(panel1);

The code isn't that well tested, but it seems the index order is from left to right and from top to bottom, as when reading a text. If no radio button is found, the method returns -1.

Update: It turned out my first attempt didn't work if there's no radio button inside the control. I added a try and catch block to fix that, and the method now seems to work.

There's no easy way to do it. This is kind of the point of hashing the password in the first place. :)

One thing you should be able to do is set a temporary password for them manually and send them that.

I hesitate to mention this because it's a bad idea (and it's not guaranteed to work anyway), but you could try looking up the hash in a rainbow table like milw0rm to see if you can recover the old password that way.

Here is a great article using Restkit

It explains on serializing nested data into JSON and attaching the data to a HTTP POST request.

Double check your jQuery references. It is possible that you are either referencing it more than once or you are calling your function too early (before jQuery is defined). You can try as mentioned in my comments and put any jQuery reference at the top of your file (in the head) and see if that helps.

If you use the encapsulation of jQuery it shouldn't help in this case. Please try it because I think it is prettier and more obvious, but if jQuery is not defined you will get the same errors.

In the end... jQuery is not currently defined.

I think that maybe it is because you are declaring a variable that you already declared:

var Name = new Array(6);
//...
var Name[0] = Name_cell.getValue();  //  <-- Here's the issue: 'var'

I think this should be like this:

var Name = new Array(6);
//...
Name[0] = Name_cell.getValue();

Tell me if it works! ;)

I have a similar question here: Writting in sub-ndarray of a ndarray in the most pythonian way. Python 2 .

Following the solution of previous post for your case the solution looks like:

columns_to_keep = [1,3] 
rows_to_keep = [1,3]

An using ix_:

x[np.ix_(rows_to_keep, columns_to_keep)] 

Which is:

array([[ 5,  7],
       [13, 15]])

I was searching for a solution to the same problem and came across this thread as well as some others but they had the same problem: if you are trying to do a handleOnChange function and you need the value from an event target, you will get cannot read property value of null or some such error. In my case, I also needed to preserve the context of this inside the debounced function since I'm executing a fluxible action. Here's my solution, it works well for my use case so I'm leaving it here in case anyone comes across this thread:

// at top of file:
var myAction = require('../actions/someAction');

// inside React.createClass({...});

handleOnChange: function (event) {
    var value = event.target.value;
    var doAction = _.curry(this.context.executeAction, 2);

    // only one parameter gets passed into the curried function,
    // so the function passed as the first parameter to _.curry()
    // will not be executed until the second parameter is passed
    // which happens in the next function that is wrapped in _.debounce()
    debouncedOnChange(doAction(myAction), value);
},

debouncedOnChange: _.debounce(function(action, value) {
    action(value);
}, 300)

This is an old post but for those who are interested:

If you want to change the default port number so when you run the "runserver" command you start with your preferred port do this:

1. Find your python installation. (you can have multiple pythons installed and you can have your virtual environment version as well so make sure you find the right one)
2. Inside the python folder locate the site-packages folder. Inside that you will find your django installation
3. Open the django folder-> core -> management -> commands
4. Inside the commands folder open up the runserver.py script with a text editor
5. Find the DEFAULT_PORT field. it is equal to 8000 by default. Change it to whatever you like DEFAULT_PORT = "8080"
6. Restart your server: python manage.py runserver and see that it uses your set port number

It works with python 2.7 but it should work with newer versions of python as well. Good luck

Add CDATA to your string resource

Strings.xml

<string name="txtCredits"><![CDATA[<a href=\"http://www.google.com\">Google</a>]]></string>

I was also having above doubt, what worked for me is

ALTER TABLE `your_table` CHANGE `property` `property` 
VARCHAR(whatever_you_want) CHARACTER SET utf8 COLLATE utf8_unicode_ci NOT NULL;  

sudo ln -s /usr/local/mysql-5.5.25-osx10.6-x86_64/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

That worked for me. I installed MySQL from a dmg file.

The easiest way is to use Homebrew. Install Homebrew and then:

brew tap caskroom/versions
brew cask install java7

You can list all available versions using the following command: brew cask search java

Update: Angular 1.1.5 added a ternary operator, so now we can simply write

<li ng-class="$first ? 'firstRow' : 'nonFirstRow'">

If you are using an earlier version of Angular, your two choices are:

1. (condition && result_if_true || !condition && result_if_false)
2. {true: 'result_if_true', false: 'result_if_false'}[condition]

item 2. above creates an object with two properties. The array syntax is used to select either the property with name true or the property with name false, and return the associated value.

E.g.,

<li class="{{{true: 'myClass1 myClass2', false: ''}[$first]}}">...</li>
 or
<li ng-class="{true: 'myClass1 myClass2', false: ''}[$first]">...</li>

$first is set to true inside an ng-repeat for the first element, so the above would apply class 'myClass1' and 'myClass2' only the first time through the loop.

With ng-class there is an easier way though: ng-class takes an expression that must evaluate to one of the following:

1. a string of space-delimited class names
2. an array of class names
3. a map/object of class names to boolean values.

An example of 1) was given above. Here is an example of 3, which I think reads much better:

 <li ng-class="{myClass: $first, anotherClass: $index == 2}">...</li>

The first time through an ng-repeat loop, class myClass is added. The 3rd time through ($index starts at 0), class anotherClass is added.

ng-style takes an expression that must evaluate to a map/object of CSS style names to CSS values. E.g.,

 <li ng-style="{true: {color: 'red'}, false: {}}[$first]">...</li>

The following takes any valid datetime value and returns the number of days in the associated month... it eliminates the ambiguity of both other answers...

 // pass in any date as parameter anyDateInMonth
function daysInMonth(anyDateInMonth) {
    return new Date(anyDateInMonth.getFullYear(), 
                    anyDateInMonth.getMonth()+1, 
                    0).getDate();}

Just ask assistance of JavaScript.

<select onchange="this.form.submit()">
    ...
</select>

I'm the asp.net security person. Firstly let me apologize that none of this is documented yet outside of the music store sample or unit tests, and it's all still being refined in terms of exposed APIs. Detailed documentation is here.

We don't want you writing custom authorize attributes. If you need to do that we've done something wrong. Instead, you should be writing authorization requirements.

Authorization acts upon Identities. Identities are created by authentication.

You say in comments you want to check a session ID in a header. Your session ID would be the basis for identity. If you wanted to use the Authorize attribute you'd write an authentication middleware to take that header and turn it into an authenticated ClaimsPrincipal. You would then check that inside an authorization requirement. Authorization requirements can be as complicated as you like, for example here's one that takes a date of birth claim on the current identity and will authorize if the user is over 18;

public class Over18Requirement : AuthorizationHandler<Over18Requirement>, IAuthorizationRequirement
{
        public override void Handle(AuthorizationHandlerContext context, Over18Requirement requirement)
        {
            if (!context.User.HasClaim(c => c.Type == ClaimTypes.DateOfBirth))
            {
                context.Fail();
                return;
            }

            var dateOfBirth = Convert.ToDateTime(context.User.FindFirst(c => c.Type == ClaimTypes.DateOfBirth).Value);
            int age = DateTime.Today.Year - dateOfBirth.Year;
            if (dateOfBirth > DateTime.Today.AddYears(-age))
            {
                age--;
            }

            if (age >= 18)
            {
                context.Succeed(requirement);
            }
            else
            {
                context.Fail();
            }
        }
    }
}

Then in your ConfigureServices() function you'd wire it up

services.AddAuthorization(options =>
{
    options.AddPolicy("Over18", 
        policy => policy.Requirements.Add(new Authorization.Over18Requirement()));
});

And finally, apply it to a controller or action method with

[Authorize(Policy = "Over18")]

For comparing 2 strings, either use the built in function strcmp() using header file string.h

if(strcmp(a,b)==0)
    printf("Entered strings are equal");
else
    printf("Entered strings are not equal");

OR you can write your own function like this:

int string_compare(char str1[], char str2[])
{
    int ctr=0;

    while(str1[ctr]==str2[ctr])
    {
        if(str1[ctr]=='\0'||str2[ctr]=='\0')
            break;
        ctr++;
    }
    if(str1[ctr]=='\0' && str2[ctr]=='\0')
        return 0;
    else
        return -1;
}

LEFT OUTER JOIN

SELECT * FROM A, B WHERE A.column = B.column(+)

RIGHT OUTER JOIN

SELECT * FROM A, B WHERE A.column (+)= B.column

Even if there are tools that allow you to mock your database in one way or another (e.g. jOOQ's MockConnection, which can be seen in this answer - disclaimer, I work for jOOQ's vendor), I would advise not to mock larger databases with complex queries.

Even if you just want to integration-test your ORM, beware that an ORM issues a very complex series of queries to your database, that may vary in

• syntax
• complexity
• order (!)

Mocking all that to produce sensible dummy data is quite hard, unless you're actually building a little database inside your mock, which interprets the transmitted SQL statements. Having said so, use a well-known integration-test database that you can easily reset with well-known data, against which you can run your integration tests.

While JS is probably the way to go, it could be done with HTML and CSS only.

Here you have a fake radio button which is really a label for a real hidden radio button. By doing that, you get exactly the effect you need.

<style>
   #uncheck>input { display: none }
   input:checked + label { display: none }
   input:not(:checked) + label + label{ display: none } 
</style>

<div id='uncheck'>
  <input type="radio" name='food' id="box1" /> 
  Pizza 
    <label for='box1'>&#9678;</label> 
    <label for='box0'>&#9673;</label>
  <input type="radio" name='food' id="box2" /> 
  Ice cream 
    <label for='box2'>&#9678;</label> 
    <label for='box0'>&#9673;</label>
  <input type="radio" name='food' id="box0" checked />
</div>

See it here: https://jsfiddle.net/tn70yxL8/2/

Now, that assumes you need non-selectable labels.

If you were willing to include the labels, you can technically avoid repeating the "uncheck" label by changing its text in CSS, see here: https://jsfiddle.net/7tdb6quy/2/

Create a batch file with the following lines:

start foo.exe
start bar.exe
start baz.exe 

The start command runs your command in a new window, so all 3 commands would run asynchronously.

In VBA (and VB.NET) the line terminator (carriage return) is used to signal the end of a statement. To break long statements into several lines, you need to

Use the line-continuation character, which is an underscore (_), at the point at which you want the line to break. The underscore must be immediately preceded by a space and immediately followed by a line terminator (carriage return).

(From How to: Break and Combine Statements in Code)

In other words: Whenever the interpreter encounters the sequence <space>_<line terminator>, it is ignored and parsing continues on the next line. Note, that even when ignored, the line continuation still acts as a token separator, so it cannot be used in the middle of a variable name, for example. You also cannot continue a comment by using a line-continuation character.

To break the statement in your question into several lines you could do the following:

U_matrix(i, j, n + 1) = _
     k * b_xyt(xi, yi, tn) / (4 * hx * hy) * U_matrix(i + 1, j + 1, n) + _
     (k * (a_xyt(xi, yi, tn) / hx ^ 2 + d_xyt(xi, yi, tn) / (2 * hx)))

(Leading whitespaces are ignored.)

Python 3.8+

y = pow(x, -1, p)

Maybe someone will find this useful (from wikibooks):

def egcd(a, b):
    if a == 0:
        return (b, 0, 1)
    else:
        g, y, x = egcd(b % a, a)
        return (g, x - (b // a) * y, y)

def modinv(a, m):
    g, x, y = egcd(a, m)
    if g != 1:
        raise Exception('modular inverse does not exist')
    else:
        return x % m

You can start reading from here jQuery.ajax()

Actually Controller Action is a public method which can be accessed through Url. So any call of an Action from an Ajax call, either MicrosoftMvcAjax or jQuery can be made. For me, jQuery is the simplest one. It got a lots of examples in the link I gave above. The typical example for an ajax call is like this.

$.ajax({
    // edit to add steve's suggestion.
    //url: "/ControllerName/ActionName",
    url: '<%= Url.Action("ActionName", "ControllerName") %>',
    success: function(data) {
         // your data could be a View or Json or what ever you returned in your action method 
         // parse your data here
         alert(data);
    }
});

I tried both

npm rebuild node-sass

and

npm install --save node-sass

Later by seeing EACCESS, i checked the folder permission of /node_modules, which was not 777 permission

Then I gave

chmod -R 777 *

-R for recursively(setting the same permission not in the dir but also inside nested sub dir) * is for all files in current directory

What is file permission

To check for permission you can use

ls -l

If u don't know about it, first see here, then check the url

Every file and directory has permission of 'rwx'(read, write, execute). and if 'x' permission is not there, then you can not execture, if no 'w', you can not write into the file. if some thing is missiing it will show in place of r/w/x with '-'. So, if 'x' permission is not there, it will show like 'rw-'

And there will be 3 category of user Owner(who created the file/directory), Group(some people who shares same permission and user previlege), Others(general public)

So 1st letter is 'd'(if it is a directory) or '-'(if it is not a directory), followed by rwx for owner, followed by for group, followed by other

drwxrwxrwx

For example, for 'node_modules'directory I want to give permission to owner all permission and for rest only read, then it will be

drwxr--r--

And about the number assume for 'r/w/x' it is 1 and for '-' it is 0, 777, first 7 is for owner, followed by group, followed by other

Let's assume the permission is rwxr-xrw-

Now 'rwx' is like '111' and it's equivalent decimal is 1*2^2+1*2^1+1*2^0=7

Now 'r-x' is like '101' and it's equivalent decimal is 1*2^2+0*2^1+1*2^0=5

Now 'rw-' is like '110' and it's equivalent decimal is 1*2^2+1*2^1+0*2^0=6

So, it will be 756

Implementing heartbeat into your system might be a solution. This is only possible if both client and server are under your control. You can have a DateTime object keeping track of the time when the last bytes were received from the socket. And assume that the socket not responded over a certain interval are lost. This will only work if you have heartbeat/custom keep alive implemented.

how's this one?

def global_index(lst, test):
    return ( pair[0] for pair in zip(range(len(lst)), lst) if test(pair[1]) )

Usage:

>>> global_index([1, 2, 3, 4, 5, 6], lambda x: x>3)
<generator object <genexpr> at ...>
>>> list(_)
[3, 4, 5]

  <style name="AppTheme2" parent="AppTheme">
    <!-- Customize your theme here. -->
    <item name="colorControlNormal">#fff</item>
    <item name="colorControlActivated">#fff</item></style>    

add this to styles and set TextInputLayout Theam to App2 and it will work ;)

simplexml_load_file() interprets an XML file (either a file on your disk or a URL) into an object. What you have in $feed is a string.

You have two options:

• Use file_get_contents() to get the XML feed as a string, and use e simplexml_load_string():

  $feed = file_get_contents('...');
  $items = simplexml_load_string($feed);
  

• Load the XML feed directly using simplexml_load_file():

  $items = simplexml_load_file('...');
  

Use GETDATE()

Returns the current database system timestamp as a datetime value without the database time zone offset. This value is derived from the operating system of the computer on which the instance of SQL Server is running.

UPDATE table SET date = GETDATE()

If there is no sub-directory, you can also take

ls | xargs -I {} dos2unix "{}"

I had the same issue in cPanel 92.0.3 and it was solved through this solution:

In cPanel go to the below directory

software --> select PHP version--> option--> upload_max_filesize 

Then choose the optional size to upload your files.

TL;DR

input function in Python 2.7, evaluates whatever your enter, as a Python expression. If you simply want to read strings, then use raw_input function in Python 2.7, which will not evaluate the read strings.

If you are using Python 3.x, raw_input has been renamed to input. Quoting the Python 3.0 release notes,

raw_input() was renamed to input(). That is, the new input() function reads a line from sys.stdin and returns it with the trailing newline stripped. It raises EOFError if the input is terminated prematurely. To get the old behavior of input(), use eval(input())

In Python 2.7, there are two functions which can be used to accept user inputs. One is input and the other one is raw_input. You can think of the relation between them as follows

input = eval(raw_input)

Consider the following piece of code to understand this better

>>> dude = "thefourtheye"
>>> input_variable = input("Enter your name: ")
Enter your name: dude
>>> input_variable
'thefourtheye'

input accepts a string from the user and evaluates the string in the current Python context. When I type dude as input, it finds that dude is bound to the value thefourtheye and so the result of evaluation becomes thefourtheye and that gets assigned to input_variable.

If I enter something else which is not there in the current python context, it will fail will the NameError.

>>> input("Enter your name: ")
Enter your name: dummy
Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "<string>", line 1, in <module>
NameError: name 'dummy' is not defined

Security considerations with Python 2.7's input:

Since whatever user types is evaluated, it imposes security issues as well. For example, if you have already loaded os module in your program with import os, and then the user types in

os.remove("/etc/hosts")

this will be evaluated as a function call expression by python and it will be executed. If you are executing Python with elevated privileges, /etc/hosts file will be deleted. See, how dangerous it could be?

To demonstrate this, let's try to execute input function again.

>>> dude = "thefourtheye"
>>> input("Enter your name: ")
Enter your name: input("Enter your name again: ")
Enter your name again: dude

Now, when input("Enter your name: ") is executed, it waits for the user input and the user input is a valid Python function invocation and so that is also invoked. That is why we are seeing Enter your name again: prompt again.

So, you are better off with raw_input function, like this

input_variable = raw_input("Enter your name: ")

If you need to convert the result to some other type, then you can use appropriate functions to convert the string returned by raw_input. For example, to read inputs as integers, use the int function, like shown in this answer.

In python 3.x, there is only one function to get user inputs and that is called input, which is equivalent to Python 2.7's raw_input.

[EDIT] The expected output of the pluck function has changed from Laravel 5.1 to 5.2. Hence why it is marked as deprecated in 5.1

In Laravel 5.1, pluck gets a single column's value from the first result of a query.

In Laravel 5.2, pluck gets an array with the values of a given column. So it's no longer deprecated, but it no longer do what it used to.

So short answer is use the value function if you want one column from the first row and you are using Laravel 5.1 or above.

Thanks to Tomas Buteler for pointing this out in the comments.

[ORIGINAL] For anyone coming across this question who is using Laravel 5.1, pluck() has been deprecated and will be removed completely in Laravel 5.2.

Consider future proofing your code by using value() instead.

return DB::table('users')->where('username', $username)->value('groupName');

Handle the Worksheet_Change event or the Workbook_SheetChange event.

The event handlers take an argument "Target As Range", so you can check if the range that's changing includes the cell you're interested in.

In mechanical terms a COMMIT makes a transaction. That is, a transaction is all the activity (one or more DML statements) which occurs between two COMMIT statements (or ROLLBACK).

In Oracle a DDL statement is a transaction in its own right simply because an implicit COMMIT is issued before the statement is executed and again afterwards. TRUNCATE is a DDL command so it doesn't need an explicit commit because calling it executes an implicit commit.

From a system design perspective a transaction is a business unit of work. It might consist of a single DML statement or several of them. It doesn't matter: only full transactions require COMMIT. It literally does not make sense to issue a COMMIT unless or until we have completed a whole business unit of work.

This is a key concept. COMMITs don't just release locks. In Oracle they also release latches, such as the Interested Transaction List. This has an impact because of Oracle's read consistency model. Exceptions such as ORA-01555: SNAPSHOT TOO OLD or ORA-01002: FETCH OUT OF SEQUENCE occur because of inappropriate commits. Consequently, it is crucial for our transactions to hang onto locks for as long as they need them.

It's possible to "natively" select by value:

dropdownlist.select(1);

Caution, member enumeration only works if the collection itself has no member of the same name. So if you had an array of FileInfo objects, you couldn't get an array of file lengths by using

 $files.length # evaluates to array length

And before you say "well obviously", consider this. If you had an array of objects with a capacity property then

 $objarr.capacity

would work fine UNLESS $objarr were actually not an [Array] but, for example, an [ArrayList]. So before using member enumeration you might have to look inside the black box containing your collection.

(Note to moderators: this should be a comment on rageandqq's answer but I don't yet have enough reputation.)

Suggestion 1

When you add an object to $stateProvider.state that object is then passed with the state. So you can add additional properties which you can read later on when needed.

Example route configuration

$stateProvider
.state('public', {
    abstract: true,
    module: 'public'
})
.state('public.login', {
    url: '/login',
    module: 'public'
})
.state('tool', {
    abstract: true,
    module: 'private'
})
.state('tool.suggestions', {
    url: '/suggestions',
    module: 'private'
});

The $stateChangeStart event gives you acces to the toState and fromState objects. These state objects will contain the configuration properties.

Example check for the custom module property

$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
    if (toState.module === 'private' && !$cookies.Session) {
        // If logged out and transitioning to a logged in page:
        e.preventDefault();
        $state.go('public.login');
    } else if (toState.module === 'public' && $cookies.Session) {
        // If logged in and transitioning to a logged out page:
        e.preventDefault();
        $state.go('tool.suggestions');
    };
});

I didn't change the logic of the cookies because I think that is out of scope for your question.

Suggestion 2

You can create a Helper to get you this to work more modular.

Value publicStates

myApp.value('publicStates', function(){
    return {
      module: 'public',
      routes: [{
        name: 'login', 
        config: { 
          url: '/login'
        }
      }]
    };
});

Value privateStates

myApp.value('privateStates', function(){
    return {
      module: 'private',
      routes: [{
        name: 'suggestions', 
        config: { 
          url: '/suggestions'
        }
      }]
    };
});

The Helper

myApp.provider('stateshelperConfig', function () {
  this.config = {
    // These are the properties we need to set
    // $stateProvider: undefined
    process: function (stateConfigs){
      var module = stateConfigs.module;
      $stateProvider = this.$stateProvider;
      $stateProvider.state(module, {
        abstract: true,
        module: module
      });
      angular.forEach(stateConfigs, function (route){
        route.config.module = module;
        $stateProvider.state(module + route.name, route.config);
      });
    }
  };

  this.$get = function () {
    return {
      config: this.config
    };
  };
});

Now you can use the helper to add the state configuration to your state configuration.

myApp.config(['$stateProvider', '$urlRouterProvider', 
    'stateshelperConfigProvider', 'publicStates', 'privateStates',
  function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
    helper.config.$stateProvider = $stateProvider;
    helper.process(publicStates);
    helper.process(privateStates);
}]);

This way you can abstract the repeated code, and come up with a more modular solution.

Note: the code above isn't tested

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt


def butter_lowpass(cutoff, fs, order=5):
    nyq = 0.5 * fs
    normal_cutoff = cutoff / nyq
    b, a = butter(order, normal_cutoff, btype='low', analog=False)
    return b, a

def butter_lowpass_filter(data, cutoff, fs, order=5):
    b, a = butter_lowpass(cutoff, fs, order=order)
    y = lfilter(b, a, data)
    return y


# Filter requirements.
order = 6
fs = 30.0       # sample rate, Hz
cutoff = 3.667  # desired cutoff frequency of the filter, Hz

# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)

# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()


# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0         # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data.  We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)

plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()

plt.subplots_adjust(hspace=0.35)
plt.show()

Add an additional div around all container divs you want the drop shadow to encapsulate. Add the classes drop-shadow and container to the additional div. The class .container will keep the fluidity. Use the class .drop-shadow (or whatever you like) to add the box-shadow property. Then target the .drop-shadow div and negate the unwanted styles .container adds--such as left & right padding.

Example: http://jsfiddle.net/SHLu4/2/

It'll be something like:

<div class="container drop-shadow">
    <div class="container">
        <div class="row">
            <div class="col-md-8">Main Area</div>
            <div class="col-md-4">Side Area</div>
        </div>
    </div>
</div>

And your CSS:

<style>
    .drop-shadow {
        -webkit-box-shadow: 0 0 5px 2px rgba(0, 0, 0, .5);
        box-shadow: 0 0 5px 2px rgba(0, 0, 0, .5);
    }
    .container.drop-shadow {
        padding-left:0;
        padding-right:0;
    }
</style>

There might be performance issues, std::endl forces a flush of the output stream.

var var1 = "something";
var var2 = "something_else";
switch(var1 + "|" + var2) {
    case "something|something_else":
        ...
        break;
    case "something|...":
        break;
    case "...|...":
        break;
}

If you have 5 possibilities for each one you will get 25 cases.

Here is a link to an excellent wiki that explains how to put greek symbols in ggplot2. In summary, here is what you do to obtain greek symbols

1. Text Labels: Use parse = T inside geom_text or annotate.
2. Axis Labels: Use expression(alpha) to get greek alpha.
3. Facet Labels: Use labeller = label_parsed inside facet.
4. Legend Labels: Use bquote(alpha == .(value)) in legend label.

You can see detailed usage of these options in the link

EDIT. The objective of using greek symbols along the tick marks can be achieved as follows

require(ggplot2);
data(tips);
p0 = qplot(sex, data = tips, geom = 'bar');
p1 = p0 + scale_x_discrete(labels = c('Female' = expression(alpha),
                                      'Male'   = expression(beta)));
print(p1);

For complete documentation on the various symbols that are available when doing this and how to use them, see ?plotmath.

Since 2019 you can now use the new functionality called Github package registry.

Basically the process is:

• generate a new personal access token from the github settings
• add repository and token info in your settings.xml

• deploy using

  mvn deploy -Dregistry=https://maven.pkg.github.com/yourusername -Dtoken=yor_token  
  

I had been struggling with this question. I discovered you only really need one function. explode('>', $html); The single common denominator to any tag is < and >. Then after that it's usually quotation marks ( " ). You can extract information so easily once you find the common denominator. This is what I came up with:

$html = file_get_contents('http://some_page.html');

$h = explode('>', $html);

foreach($h as $k => $v){

    $v = trim($v);//clean it up a bit

    if(preg_match('/^(<script[.*]*)/ius', $v)){//my regex here might be questionable

        $counter = $k;//match opening tag and start counter for backtrace

        }elseif(preg_match('/([.*]*<\/script$)/ius', $v)){//but it gets the job done

            $script_length = $k - $counter;

            $counter = 0;

            for($i = $script_length; $i >= 0; $i--){
                $h[$k-$i] = '';//backtrace and clear everything in between
                }
            }           
        }
for($i = 0; $i <= count($h); $i++){
    if($h[$i] != ''){
    $ht[$i] = $h[$i];//clean out the blanks so when we implode it works right.
        }
    }
$html = implode('>', $ht);//all scripts stripped.


echo $html;

I see this really only working for script tags because you will never have nested script tags. Of course, you can easily add more code that does the same check and gather nested tags.

I call it accordion coding. implode();explode(); are the easiest ways to get your logic flowing if you have a common denominator.

I had to restart Android Studio for changing the sdk after installing a new one. Then Android Studio asked me for configuring my SDK and let me do it.

I'm afraid this isn't possible with foreach. But I can suggest you a simple old-styled for-loops:

    List<String> l = new ArrayList<String>();

    l.add("a");
    l.add("b");
    l.add("c");
    l.add("d");

    // the array
    String[] array = new String[l.size()];

    for(ListIterator<String> it =l.listIterator(); it.hasNext() ;)
    {
        array[it.nextIndex()] = it.next();
    }

Notice that, the List interface gives you access to it.nextIndex().

(edit)

To your changed example:

    for(ListIterator<String> it =l.listIterator(); it.hasNext() ;)
    {
        int i = it.nextIndex();
        doSomethingWith(it.next(), i);
    }

I wouldn't really class this as "AJAX". Anyway, something like following should do the trick:

document.body.style.backgroundColor = 'pink';

This is my working code:

@Html.EditorFor(model => model.PropertyName, new { htmlAttributes = new { @class = "form-control", @Value = "123" } })

my difference with other answers is using Value inside the htmlAttributes array

The solution above won't work if the original string has no spaces.

Try this:

var title = "This is your title";
var shortText = jQuery.trim(title).substring(0, 10)
                          .trim(this) + "...";

position: absolute will position the element by coordinates, relative to the closest positioned ancestor, i.e. the closest parent which isn't position: static.

Have your four divs nested inside the target div, give the target div position: relative, and use position: absolute on the others.

Structure your HTML similar to this:

<div id="container">
  <div class="top left"></div>
  <div class="top right"></div>
  <div class="bottom left"></div>
  <div class="bottom right"></div>
</div>

And this CSS should work:

#container {
  position: relative;
}

#container > * {
  position: absolute;
}

.left {
  left: 0;
}

.right {
  right: 0;
}

.top {
  top: 0;
}

.bottom {
  bottom: 0;
}

OK, here's what we do: open the file, read it line by line, and split it by tabs. Then we grab the second integer and loop through the rest to find the path.

StreamReader reader = File.OpenText("filename.txt");
string line;
while ((line = reader.ReadLine()) != null) 
{
    string[] items = line.Split('\t');
    int myInteger = int.Parse(items[1]);   // Here's your integer.

    // Now let's find the path.
    string path = null;
    foreach (string item in items) 
    {
        if (item.StartsWith("item\\") && item.EndsWith(".ddj"))
            path = item;
    }

    // At this point, `myInteger` and `path` contain the values we want
    // for the current line. We can then store those values or print them,
    // or anything else we like.
}

Follow the below steps to do so_

1. Rename your APK file(e.g., rename your APK file to .zip Ex- test.apk -> test.zip) & extract resultant zip file.
2. Copy your .dex file in to dex2jar folder.
3. Run setclasspath.bat. This should be run because this data is used in the next step.
4. Go to Windows Command prompt, change the folder path to the path of your dex2jar folder and run the command as follows: d2j-dex2jar.bat classes.dex
5. enjoy!! Your jar file will be ready in the same folder with name classes_dex2jar.jar.

Hope this helps you and All reading this... :)

There is now a plugin (since end of 2012) that can take care of this: gensth/ProjectLocationUpdater on GitHub.

First()

When you know that result contain more than 1 element expected and you should only the first element of sequence.

FirstOrDefault()

FirstOrDefault() is just like First() except that, if no element match the specified condition than it returns default value of underlying type of generic collection. It does not throw InvalidOperationException if no element found. But collection of element or a sequence is null than it throws an exception.

The techniques outlined above describe your options pretty well. But what are the users seeing? I can't imagine how a basic conflict like this between you and whoever is responsible for the software can't end up in confusion and antagonism with the users.

I'd do everything I could to find some other way out of the impasse - because other people could easily see any change you make as escalating the problem.

EDIT:

I'll score my first "undelete" and admit to posting the above when this question first appeared. I of course chickened out when I saw that it was from JOEL SPOLSKY. But it looks like it landed somewhere near. Don't need votes, but I'll put it on the record.

IME, triggers are so seldom the right answer for anything other than fine-grained integrity constraints outside the realm of business rules.

The problem is not the range, the problem is how the end of slice is calculated. with a fixed number 10 the simple for loop is ok but with a calculated size like bfl.Size() you get a function-call on every iteration. A simple range over int32 would help because this evaluate the bfl.Size() only once.

type BFLT PerfServer   
  func (this *BFLT) Call() {
    bfl := MqBufferLCreateTLS(0)                                                                                   
    for this.ReadItemExists() {                                                                                    
      bfl.AppendU(this.ReadU())                                                                                    
    }
    this.SendSTART()
    // size := bfl.Size() 
    for i := int32(0); i < bfl.Size() /* size */; i++ {                                                                             
      this.SendU(bfl.IndexGet(i))                                                                                  
    }
    this.SendRETURN()
  }

If you don't need a signed integer, this is an alternative that uses a slightly different approach, is easy to read and doesn't require an import:

def distance(a, b):
  if a > 0 and b > 0:
    return max(a, b) - min(a, b)
  elif a < 0 and b < 0:
    return abs(a - b)
  elif a == b:
    return 0
  return abs(a - 0) + abs(b - 0)

There's no difference, == is a synonym for = (for the C/C++ people, I assume). See here, for example.

You could double-check just to be really sure or just for your interest by looking at the bash source code, should be somewhere in the parsing code there, but I couldn't find it straightaway.

I would try any(byte[].class)

rm -rf some_dir

-r "recursive" -f "force" (suppress confirmation messages)

Be careful!

mailx -s "subjec_of_mail" [email protected] < file_name

through mailx utility we can send a file from unix to mail server. here in above code we can see first parameter is -s "subject of mail" the second parameter is mail ID and the last parameter is name of file which we want to attach

The easiest way of getting UTC time in a conventional format is as follows:

new Date().toISOString()
"2016-06-03T23:15:33.008Z"

Another way (worked for 2015) is open "Install/remove programs" (Apps & features), find Visual Studio, select Modify. In opened window, press Modify, check

• Languages -> Visual C++ -> Common tools for Visual C++
• Windows and web development -> Tools for universal windows apps -> Tools (1.4.1) and Windows 10 SDK ([version])
• Windows and web development -> Tools for universal windows apps -> Windows 10 SDK ([version])

and install. Then right click on solution -> Re-target and it will compile

It seems however that splitting in the middle of the values of a for loop doesn't need a caret(and actually trying to use one will be considered a syntax error). For example,

for %n in (hello
bye) do echo %n

Note that no space is even needed after hello or before bye.

All answers above are incomplete, the problem here lies in linker ld rather than compiler collect2: ld returned 1 exit status. When you are compiling your fib.c to object:

$ gcc -c fib.c
$ nm fib.o
0000000000000028 T fibo
                 U floor
                 U _GLOBAL_OFFSET_TABLE_
0000000000000000 T main
                 U pow
                 U printf

Where nm lists symbols from object file. You can see that this was compiled without an error, but pow, floor, and printf functions have undefined references, now if I will try to link this to executable:

$ gcc fib.o
fib.o: In function `fibo':
fib.c:(.text+0x57): undefined reference to `pow'
fib.c:(.text+0x84): undefined reference to `floor'
collect2: error: ld returned 1 exit status

Im getting similar output you get. To solve that, I need to tell linker where to look for references to pow, and floor, for this purpose I will use linker -l flag with m which comes from libm.so library.

$ gcc fib.o -lm
$ nm a.out

00000000000005f0 T _start
0000000000201010 D __TMC_END__

You can now see, functions pow, floor are linked to GLIBC_2.2.5.

Parameters order is important too, unless your system is configured to use shared librares by default, my system is not, so when I issue:

$ gcc -lm fib.o
fib.o: In function `fibo':
fib.c:(.text+0x57): undefined reference to `pow'
fib.c:(.text+0x84): undefined reference to `floor'
collect2: error: ld returned 1 exit status

Note -lm flag before object file. So in conclusion, add -lm flag after all other flags, and parameters, to be sure.

I wasn't satisfied with the accepted answer so I created some scripts to do this for you available on Github. These should help anyone who wants to use git svn clone but doesn't want to clone the entire repository and doesn't want to hunt for a specific revision to clone from in the middle of the history (maybe you're cloning a bunch of repos). Here we can just clone the last N revisions:

Use git svn clone to clone the last 50 revisions

# -u    The SVN URL to clone
# -l    The limit of revisions
# -o    The output directory

./git-svn-cloneback.sh -u https://server/project/trunk -l 50 -o myproj --authors-file=svn-authors.txt

Find the previous N revision from an SVN repo

# -u    The SVN URL to clone
# -l    The limit of revisions

./svn-lookback.sh -u https://server/project/trunk -l 5     

Works for me this way (similar to @Amey and @user4642224 code, but shorter a bit):

from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy, ProxyType

prox = Proxy()
prox.proxy_type = ProxyType.MANUAL
prox.http_proxy = "ip_addr:port"
prox.socks_proxy = "ip_addr:port"
prox.ssl_proxy = "ip_addr:port"

capabilities = webdriver.DesiredCapabilities.CHROME
prox.add_to_capabilities(capabilities)

driver = webdriver.Chrome(desired_capabilities=capabilities)

For right pad you need String.format("%0$-15s", str)

i.e. - sign will "right" pad and no - sign will "left" pad

See my example:

import java.util.Scanner;
 
public class Solution {
 
    public static void main(String[] args) {
            Scanner sc=new Scanner(System.in);
            System.out.println("================================");
            for(int i=0;i<3;i++)
            {
                String s1=sc.nextLine();
                
                
                Scanner line = new Scanner( s1);
                line=line.useDelimiter(" ");
               
                String language = line.next();
                int mark = line.nextInt();;
                
                System.out.printf("%s%03d\n",String.format("%0$-15s", language),mark);
                
            }
            System.out.println("================================");
 
    }
}

The input must be a string and a number

example input : Google 1

the easiest way, you can copy the newline (copy empty 2 line in text editor) then paste on replace with.

Sorry to bring up an old post, but I wanted to provide another answer for anyone that comes across this thread.

I had the same problem. No matter what I did, the image just looked like it was complete black. I tried making multiple consecutive calls to cvQueryFrame and noticed that when I made 5 or more, I could see the image. So I started removing the calls one by one to see where the "breaking point" was. What I ended up finding was that the image got darker and darker as I removed each call. Making just a single call provided an image that was almost completely black, but if I looked very closely, I could make out my image.

I tried 10 consecutive calls to test my theory, and sure enough, I was given a very bright image, considering that I'm in a dimly lit room. Hopefully, this was the same problem you were encountering.

I don't know much about imaging, but it looks like multiple consecutive calls to cvQueryFrame increases the length of exposure for the camera. This definitely fixes the problem, though it doesn't seem like the most elegant solution. I'm going to see if I can find a parameter that will increase the exposure, or perhaps some other parameter that will brighten up my images.

Good luck!

Another alternative which is similar to the accepted answer by @BenBolker is redefining the coordinates of the existing plot when adding a second set of points.

Here is a minimal example.

Data:

x  <- 1:10
y1 <- rnorm(10, 100, 20)
y2 <- rnorm(10, 1, 1)

Plot:

par(mar=c(5,5,5,5)+0.1, las=1)

plot.new()
plot.window(xlim=range(x), ylim=range(y1))
points(x, y1, col="red", pch=19)
axis(1)
axis(2, col.axis="red")
box()

plot.window(xlim=range(x), ylim=range(y2))
points(x, y2, col="limegreen", pch=19)
axis(4, col.axis="limegreen")

In my opinion, I think it's important to explain the why behind the need for a GROUP BY in your SQL when summing with OVER() clause and why you are getting repeated lines of data when you are expecting one row per BrandID.

Take this example: You need to aggregate the total sale price of each order line, per specific order category, between two dates, but you also need to retain individual order data in your final results. A SUM() on the SalesPrice column would not allow you to get the correct totals because it would require a GROUP BY, therefore squashing the details because you wouldn't be able to keep the individual order lines in the select statement.

Many times we see a #temp table, @table variable, or CTE filled with the sum of our data and grouped up so we can join to it again later to get a column of the sums we need. This can add processing time and extra lines of code. Instead, use OVER(PARTITION BY ()) like this:

SELECT
  OrderLine, 
  OrderDateTime, 
  SalePrice, 
  OrderCategory,
  SUM(SalePrice) OVER(PARTITION BY OrderCategory) AS SaleTotalPerCategory
FROM tblSales 
WHERE OrderDateTime BETWEEN @StartDate AND @EndDate

Notice we are not grouping and we have individual order lines column selected. The PARTITION BY in the last column will return us a sales price total for each row of data in each category. What the last column essentially says is, we want the sum of the sale price (SUM(SalePrice)) over a partition of my results and by a specified category (OVER(PARTITION BY CategoryHere)).

If we remove the other columns from our select statement, and leave our final SUM() column, like this:

SELECT
  SUM(SalePrice) OVER(PARTITION BY OrderCategory) AS SaleTotalPerCategory
FROM tblSales 
WHERE OrderDateTime BETWEEN @StartDate AND @EndDate

The results will still repeat this sum for each row in our original result set. The reason is this method does not require a GROUP BY. If you don't need to retain individual line data, then simply SUM() without the use of OVER() and group up your data appropriately. Again, if you need an additional column with specific totals, you can use the OVER(PARTITION BY ()) method described above without additional selects to join back to.

The above is purely for explaining WHY he is getting repeated lines of the same number and to help understand what this clause provides. This method can be used in many ways and I highly encourage further reading from the documentation here:

Over Clause

Perhaps you can do some introspection on the db file. The protocol is relatively simple (yet not well documented), so you could write a parser for it to determine which individual keys are taking up a lot of space.

New suggestions:

Have you tried using MONITOR to see what is being written, live? Perhaps you can find the issue with the data in motion.

I've seen occasional problems with Eclipse forgetting that built-in classes (including Object and String) exist. The way I've resolved them is to:

• On the Project menu, turn off "Build Automatically"
• Quit and restart Eclipse
• On the Project menu, choose "Clean…" and clean all projects
• Turn "Build Automatically" back on and let it rebuild everything.

This seems to make Eclipse forget whatever incorrect cached information it had about the available classes.

You will have to install the "Developer Tools" that are provided as optional packages in OS X installation disks.

if /dir/on/host doesn't exist, it is created on the host and the empty content is mounted in the container at /var/www/html. Whatever content you had before in /var/www/html inside the container is inaccessible, until you unmount the volume; the new mount is hiding the old content.

Another option, related to Kevin's, is use __FILE__, but instead replace the php file name from within it:

<?php

$docRoot = str_replace($_SERVER['SCRIPT_NAME'], '', __FILE__);
require_once($docRoot . '/lib/include.php');

?>

I've been using this for a while. The only problem is sometimes you don't have $_SERVER['SCRIPT_NAME'], but sometimes there is another variable similar.

Use the text method [text()] to get text in the div element, by identifing the element by class or id.

you could always create a new list which is a result of adding two lists.

>>> k
[1, 2, 3, 4, 7, 9]

Lists are mutable sequences so I guess it makes sense to modify the original lists by extend or append.

This problem can occur when you reference your web.config (or app.config) connection strings by index...

var con = ConfigurationManager.ConnectionStrings[0].ConnectionString;

The zero based connection string is not always the one in your config file as it inherits others by default from further up the stack.

The recommended approaches are to access your connection by name...

var con = ConfigurationManager.ConnectionStrings["MyConnection"].ConnectionString;

or to clear the connnectionStrings element in your config file first...

<connectionStrings>
    <clear/>
    <add name="MyConnection" connectionString="...

For SQL Server 2005 onwards, you can do this with CROSS APPLY and a table-valued function.

• Using CROSS APPLY in SQL Server 2005

Just for clarity, I'm referring to those cases where the stored procedure can be converted into a table valued function.

I've tried @bobince's example with a slight modifications:

<html>
<head>
    <title>Test</title>
</head>
<body>
    <textarea id="log" rows="20" cols="40"></textarea>
    <br />
    <button id="act">Run</button>
    <script type="text/javascript">
        let l= document.getElementById('log');
        let b = document.getElementById('act');
        let s = 0;

        b.addEventListener('click', function() {
            l.value += 'click begin\n';

            s = 10;
            let s2 = s;

            alert('alert!');

            s = s + s2;

            l.value += 'click end\n';
            l.value += `result = ${s}, should be ${s2 + s2}\n`;
            l.value += '----------\n';
        });

        window.addEventListener('resize', function() {
            if (s === 10) {
                s = 5;
            }

            l.value+= 'resize\n';
        });
    </script>
</body>
</html>

So, when you press Run, close alert popup and do a "single thread", you should see something like this:

click begin
click end
result = 20, should be 20

But if you try to run this in Opera or Firefox stable on Windows and minimize/maximize window with alert popup on screen, then there will be something like this:

click begin
resize
click end
result = 15, should be 20

I don't want to say, that this is "multithreading", but some piece of code had executed in a wrong time with me not expecting this, and now I have a corrupted state. And better to know about this behavior.

You also could allocate using new and initialize all fields by hand

package main

type Configuration struct {
    Val   string
    Proxy struct {
        Address string
        Port    string
    }
}

func main() {
    c := new(Configuration)
    c.Val = "test"
    c.Proxy.Address = "addr"
    c.Proxy.Port = "80"
}

See in playground: https://play.golang.org/p/sFH_-HawO_M

This help me a lot:

It also works for Mac OS X Lion :D

.:EDIT:. On my case the prefepane only allows to start and stop mysql, but after some issues i've uninstalled him. If you need a application to run queries and create DB, you could use: Sequel Pro (it's free) or Navicat

If you need start and stop mysql in ~/.bash_profile you can add these lines:

#For MySQL
alias mysql_start="/Library/StartupItems/MySQLCOM/MySQLCOM start"
alias mysql_stop="/Library/StartupItems/MySQLCOM/MySQLCOM stop"

After reloaded the console just call:

$mysql_start 

or

$mysql_stop 

agreding the desired action. Hope helped you.

It seems that you have forgotten to add your state server address in the config file.

 <sessionstate mode="StateServer" timeout="20" server="127.0.0.1" port="42424" />

I like to append the following to config/boot.rb:

require 'rails/commands/server'

module Rails
  class Server
    alias :default_options_alias :default_options
    def default_options
      default_options_alias.merge!(:Port => 3333)
    end    
  end
end

This would be a proper CSS solution which works for IE8/9 as well (IE8 with html5shiv ofcourse): codepen

nav {
  margin:0px auto;
  height:50px;
  background-color:gray;
  padding:10px;
  border:2px solid red;
  position: relative;
  color: white;
  z-index: 1;
}

nav:after {
  content: '';
  background: black;
  display: block;
  position: absolute;
  margin: 10px;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  z-index: -1;
}

ValueErrors :In Python, a value is the information that is stored within a certain object. To encounter a ValueError in Python means that is a problem with the content of the object you tried to assign the value to.

in your case name,lastname and email 3 parameters are there but unpaidmembers only contain 2 of them.

name, lastname, email in unpaidMembers.items() so you should refer data or your code might be
lastname, email in unpaidMembers.items() or name, email in unpaidMembers.items()

I know this is an old question, but I'd like to offer one example of how the yield keyword can be creatively used. I have really benefited from this technique. Hopefully this will be of assistance to anyone else who stumbles upon this question.

Note: Don't think about the yield keyword as merely being another way to build a collection. A big part of the power of yield comes in the fact that execution is paused in your method or property until the calling code iterates over the next value. Here's my example:

Using the yield keyword (alongside Rob Eisenburg's Caliburn.Micro coroutines implementation) allows me to express an asynchronous call to a web service like this:

public IEnumerable<IResult> HandleButtonClick() {
    yield return Show.Busy();

    var loginCall = new LoginResult(wsClient, Username, Password);
    yield return loginCall;
    this.IsLoggedIn = loginCall.Success;

    yield return Show.NotBusy();
}

What this will do is turn my BusyIndicator on, call the Login method on my web service, set my IsLoggedIn flag to the return value, and then turn the BusyIndicator back off.

Here's how this works: IResult has an Execute method and a Completed event. Caliburn.Micro grabs the IEnumerator from the call to HandleButtonClick() and passes it into a Coroutine.BeginExecute method. The BeginExecute method starts iterating through the IResults. When the first IResult is returned, execution is paused inside HandleButtonClick(), and BeginExecute() attaches an event handler to the Completed event and calls Execute(). IResult.Execute() can perform either a synchronous or an asynchronous task and fires the Completed event when it's done.

LoginResult looks something like this:

public LoginResult : IResult {
    // Constructor to set private members...

    public void Execute(ActionExecutionContext context) {
        wsClient.LoginCompleted += (sender, e) => {
            this.Success = e.Result;
            Completed(this, new ResultCompletionEventArgs());
        };
        wsClient.Login(username, password);
    }

    public event EventHandler<ResultCompletionEventArgs> Completed = delegate { };
    public bool Success { get; private set; }
}

It may help to set up something like this and step through the execution to watch what's going on.

Hope this helps someone out! I've really enjoyed exploring the different ways yield can be used.

To avoid getting the encryption error you can also try out below commands

ftp = ftplib.FTP_TLS("ftps.dummy.com")
ftp.login("username", "password")
ftp.prot_p()
file = open("filename", "rb")
ftp.storbinary("STOR filename", file)
file.close()
ftp.close()

ftp.prot_p() ensure that your connections are encrypted

Here's a chunk of code that will write values to a log file. If the file doesn't exist, it creates it, otherwise it just appends to the existing file. You need to add "using System.IO;" at the top of your code, if it's not already there.

string strLogText = "Some details you want to log.";

// Create a writer and open the file:
StreamWriter log;

if (!File.Exists("logfile.txt"))
{
  log = new StreamWriter("logfile.txt");
}
else
{
  log = File.AppendText("logfile.txt");
}

// Write to the file:
log.WriteLine(DateTime.Now);
log.WriteLine(strLogText);
log.WriteLine();

// Close the stream:
log.Close();

I had a similar issue and using %in% operator instead of the == (equality) operator was the solution:

# %in%

Hope it helps.

This one-liner is pretty much the same as your original try with a couple of additions. It works with paths including spaces, and works in both XP and Windows 7 even if the key is not found (and hides the error). %fn% will be empty if the key does not exist. This example gets the current desktop background filename:

for /f "tokens=2*" %%a in ('reg query "HKEY_CURRENT_USER\Control Panel\Desktop" /v Wallpaper 2^>^&1^|find "REG_"') do @set fn=%%b

This command uses tokens=2* with %%a as the loop variable but consumes %%b to correctly handle spaces. When using tokens=2*, the loop variable %%a is assigned the value in the second token (in this case, REG_SZ) and %%b is assigned the remainder of the line after the next group of delimiter characters, including all internal delimiter characters. This means that %%b will correctly replicate delimiter characters—even if multiple delimiter characters are clustered together. For example, the value might be C:\A weird path\blah.png. This technique of reading the value would correctly preserve the two spaces between C:\A and weird.

I know it is an old question. But I hope my answer will help somebody. I had the same issue and I think the problem is that it cannot find those .jar files in your local repository. So what I did is I added the following code to my pom.xml and it worked.

<repositories>
  <repository>
      <id>spring-milestones</id>
      <name>Spring Milestones</name>
      <url>https://repo.spring.io/libs-milestone</url>
      <snapshots>
          <enabled>false</enabled>
      </snapshots>
  </repository>
</repositories>

If you use spring-boot, you don't need to create a DataSource class, just specify the data url/username/password/driver in application.properties, then you can simply @Autowired it.

@Repository
public class JdbcRepository {

    private final JdbcTemplate jdbcTemplate;

    @Autowired
    public DynamicRepository(JdbcTemplate jdbcTemplate) {
        this.jdbcTemplate = jdbcTemplate;
    }

    public void insert() {
        jdbcTemplate.update("INSERT INTO BOOK (name, description) VALUES ('book name', 'book description')");
    }
}

Example of application.properties:

#Basic Spring Boot Config for Oracle
spring.datasource.url=jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=YourHostIP)(PORT=YourPort))(CONNECT_DATA=(SERVER=dedicated)(SERVICE_NAME=YourServiceName)))
spring.datasource.username=username
spring.datasource.password=password
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver

#hibernate config
spring.jpa.database-platform=org.hibernate.dialect.Oracle10gDialect

Then add the driver and connection pool dependencies in pom.xml

<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ojdbc7</artifactId>
    <version>12.1.0.1</version>
</dependency>

<!-- HikariCP connection pool -->
<dependency>
    <groupId>com.zaxxer</groupId>
    <artifactId>HikariCP</artifactId>
    <version>2.6.0</version>
</dependency>

See the official doc for more details.

You can use FLUSHALL which will delete all keys from your every database. Where as FLUSHDB will delete all keys from our current database.

For hexadecimal code try this

1. Get ARGB (Alpha, Red, Green, Blue) representation for the color
2. Filter out Alpha channel: & 0x00FFFFFF
3. Format out the value (as hexadecimal "X6" for hex)

For RGB one

1. Just format out Red, Green, Blue values

Implementation

private static string HexConverter(Color c) {
  return String.Format("#{0:X6}", c.ToArgb() & 0x00FFFFFF);
}

public static string RgbConverter(Color c) {
  return String.Format("RGB({0},{1},{2})", c.R, c.G, c.B);
}

Edit:

This method should no longer be needed with the arrival of MVC 3, as it will be handled automatically - http://weblogs.asp.net/scottgu/archive/2010/07/27/introducing-asp-net-mvc-3-preview-1.aspx

You can use this ObjectFilter:

    public class ObjectFilter : ActionFilterAttribute {

    public string Param { get; set; }
    public Type RootType { get; set; }

    public override void OnActionExecuting(ActionExecutingContext filterContext) {
        if ((filterContext.HttpContext.Request.ContentType ?? string.Empty).Contains("application/json")) {
            object o =
            new DataContractJsonSerializer(RootType).ReadObject(filterContext.HttpContext.Request.InputStream);
            filterContext.ActionParameters[Param] = o;
        }

    }
}

You can then apply it to your controller methods like so:

    [ObjectFilter(Param = "postdata", RootType = typeof(ObjectToSerializeTo))]
    public JsonResult ControllerMethod(ObjectToSerializeTo postdata) { ... }

So basically, if the content type of the post is "application/json" this will spring into action and will map the values to the object of type you specify.

you could even do it in this way:

sudo -u postgres psql -d myDataBase -a -f myInsertFile

If you have sudo access on machine and it's not recommended for production scripts just for test on your own machine it's the easiest way.

You can also just download and run ez_setup.py, though the SetupTools documentation no longer suggests this. Worked fine for me as recently as 2 weeks ago.

Although TripleDESCryptoServiceProvider is a safe and good method but it's too slow. If you want to refer to MSDN you will get that advise you to use AES rather TripleDES. Please check below link: http://msdn.microsoft.com/en-us/library/system.security.cryptography.tripledescryptoserviceprovider.aspx you will see this attention in the remark section:

Note A newer symmetric encryption algorithm, Advanced Encryption Standard (AES), is available. Consider using the AesCryptoServiceProvider class instead of the TripleDESCryptoServiceProvider class. Use TripleDESCryptoServiceProvider only for compatibility with legacy applications and data.

Good luck

This is a follow-up to Update (July 2018). I am on 64 bit Windows 10 but am set up to build r packages from source for both 32 and 64 bit with Rtools. My 64 bit jdk is jdk-11.0.2. When I can, I do everything in RStudio. As of March 2019, rjava is tested with <=jdk11, see github issue #157.

• Install jdks to their default location per Update (July 2018) by @Jeroen.
• In R studio, set JAVA_HOME to the 64 bit jdk

Sys.setenv(JAVA_HOME="C:/Program Files/Java/jdk-11.0.2")

• Optionally check your environmental variable

Sys.getenv("JAVA_HOME")

• Install the package per the github page recommendation

install.packages("rJava",,"http://rforge.net")

FYI, the rstudio scripting console doesn't like the double commas... but it works!

$("input").attr("disabled", true); as of... I don't know any more.

It's December 2013 and I really have no idea what to tell you.

First it was always .attr(), then it was always .prop(), so I came back here updated the answer and made it more accurate.

Then a year later jQuery changed their minds again and I don't even want to keep track of this.

Long story short, as of right now, this is the best answer: "you can use both... but it depends."

You should read this answer instead: https://stackoverflow.com/a/5876747/257493

And their release notes for that change are included here:

Neither .attr() nor .prop() should be used for getting/setting value. Use the .val() method instead (although using .attr("value", "somevalue") will continue to work, as it did before 1.6).

Summary of Preferred Usage

The .prop() method should be used for boolean attributes/properties and for properties which do not exist in html (such as window.location). All other attributes (ones you can see in the html) can and should continue to be manipulated with the .attr() method.

Or in other words:

".prop = non-document stuff"

".attr" = document stuff

... ...

May we all learn a lesson here about API stability...

• TortoiseMerge (part of ToroiseSVN) is much better than kdiff3 (I use both and can compare);
• p4merge (from Perforce) works also very well;
• Diffuse isn't so bad;
• Diffmerge from SourceGear has only one flaw in handling UTF8-files without BOM, making in unusable for this case.

This is my personal solution, based on the information here (this thread):

var Divs = new Array();    
var Elemns = document.getElementsByClassName("divisao");
    try {
        Divs = Elemns.prototype.slice.call(Elemns);
    } catch(e) {
        Divs = $A(Elemns);
    }

Where $A was described by Gareth Davis in his post:

function $A(iterable) {
  if (!iterable) return [];
  if ('toArray' in Object(iterable)) return iterable.toArray();
  var length = iterable.length || 0, results = new Array(length);
  while (length--) results[length] = iterable[length];
  return results;
}

If browser supports the best way, ok, otherwise will use the cross browser.

<?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('my_static_block_name')->toHtml() ?>

If you take a look at the source of the select method, you can see that what it does when you pass a from key is essentially:

find(:select, from, options).find(:option, value, options).select_option

In other words, it finds the <select> you're interested in, then finds the <option> within that, then calls select_option on the <option> node.

You've already pretty much done the first two things, I'd just rearrange them. Then you can tack the select_option method on the end:

find('#organizationSelect').find(:xpath, 'option[2]').select_option
