What if you compile it using another machine? A fresh installed one would be lovely. I hope your machine is not jealous.

You can just copy the job and delete the old one. If it doesn't matter that you lost the old build logs.

One way:

import os
os.listdir("/home/username/www/")

Another way:

glob.glob("/home/username/www/*")

Examples found here.

The glob.glob method above will not list hidden files.

Since I originally answered this question years ago, pathlib has been added to Python. My preferred way to list a directory now usually involves the iterdir method on Path objects:

from pathlib import Path
print(*Path("/home/username/www/").iterdir(), sep="\n")

Only you need to add other parameter in your route, the parameter is useAsDefault:true. For example, if you want the DashboardComponent as default you need to do this:

@RouteConfig([
    { path: '/Dashboard', component: DashboardComponent , useAsDefault:true},
    .
    .
    .
    ])

I recomend you to add names to your routes.

{ path: '/Dashboard',name:'Dashboard', component: DashboardComponent , useAsDefault:true}

Instead of setting a fixed path try this in your post-build command-line first:

SET VCTargetsPath=$(VCTargetsPath)

The variable '$(VCTargetsPath)' seems to be a c++-related visual-studio-macro which is not shown in c#-sdk-projects as a macro but is still available there.

we can send nested json like the following format

address[city] address[state]

Sounds to me like you could create a simple iterator with a callback for testing. Like so:

function findElements(array, predicate)
{
    var matchingIndices = [];

    for(var j = 0; j < array.length; j++)
    {
        if(predicate(array[j]))
           matchingIndices.push(j);
    }

    return matchingIndices;
}

Then you could invoke like so:

var someArray = [
     { id: 1, text: "Hello" },
     { id: 2, text: "World" },
     { id: 3, text: "Sup" },
     { id: 4, text: "Dawg" }
  ];

var matchingIndices = findElements(someArray, function(item)
   {
        return item.id % 2 == 0;
   });

// Should have an array of [1, 3] as the indexes that matched

While searching for doc to point to about how pragma are directives for the compiler, I found this NSHipster article that does the job pretty well.

I hope you'll enjoy the reading

To get the max of any column you want something like:

max(ozone$Ozone, na.rm = TRUE)

To get the max of all columns, you want:

apply(ozone, 2, function(x) max(x, na.rm = TRUE))

And to sort:

ozone[order(ozone$Solar.R),]

Or to sort the other direction:

ozone[rev(order(ozone$Solar.R)),]

Two things to keep in mind Content-Type and the Encoding

1) What if the file is css

if (/.(css)$/.test(path)) {
  res.writeHead(200, {'Content-Type': 'text/css'}); 
  res.write(data, 'utf8');
} 

2) What if the file is jpg/png

if (/.(jpg)$/.test(path)) {
  res.writeHead(200, {'Content-Type': 'image/jpg'});
  res.end(data,'Base64');
}

Above one is just a sample code to explain the answer and not the exact code pattern.

Use below command at cmd or GIT Bash or other prompt

$ npm config set proxy "http://192.168.1.101:4128"

$ npm config set https-proxy "http://192.168.1.101:4128"

where 192.168.1.101 is proxy ip and 4128 is port. change according to your proxy settings.

You are using an adjacent sibling selector (+) when the elements are not siblings. The label is the parent of the input, not it's sibling.

CSS has no way to select an element based on it's descendents (nor anything that follows it).

You'll need to look to JavaScript to solve this.

Alternatively, rearrange your markup:

<input id="foo"><label for="foo">…</label>

volatile keyword guarantees happens-before relationship among threads sharing that variable. It doesn't guarantee you that 2 or more threads won't interrupt each other while accessing that boolean variable.

It means you're trying to install an app with the same packageName as an app that's already installed on the emulator, but the one you're trying to install has a lower versionCode (integer value for your version number).

You might have installed from a separate copy of the code where the version number was higher than the copy you're working with right now. In either case, either:

• uninstall the currently installed copy

• or open up your phone's Settings > Application Manager to determine the version number for the installed app, and increment your <manifest android:versionCode to be higher in the AndroidManifest.

• or https://stackoverflow.com/a/13772620/632951

(bool)($number & 1)

or

(bool)(~ $number & 1)

That means that the definition of your function is not present in your program. You forgot to add that one.cpp to your program.

What "to add" means in this case depends on your build environment and its terminology. In MSVC (since you are apparently use MSVC) you'd have to add one.cpp to the project.

In more practical terms, applicable to all typical build methodologies, when you link you program, the object file created form one.cpp is missing.

You can use Enumerable.Except to get distinct items from lines3 which is not in lines2:

lines2.AddRange(lines3.Except(lines2));

If lines2 contains all items from lines3 then nothing will be added. BTW internally Except uses Set<string> to get distinct items from second sequence and to verify those items present in first sequence. So, it's pretty fast.

A solution with a bigger browser support then the flexbox (works in IE=9):

#wrapper {_x000D_
  -webkit-transform: scaleY(-1);_x000D_
  -ms-transform: scaleY(-1);_x000D_
  transform: scaleY(-1);_x000D_
}_x000D_
#wrapper > * {_x000D_
  -webkit-transform: scaleY(-1);_x000D_
  -ms-transform: scaleY(-1);_x000D_
  transform: scaleY(-1);_x000D_
}

<div id="wrapper">_x000D_
    <div id="firstDiv">_x000D_
        Content to be below in this situation_x000D_
    </div>_x000D_
    <div id="secondDiv">_x000D_
        Content to be above in this situation_x000D_
    </div>_x000D_
</div>_x000D_
Other elements

In contrast to the display: table; solution this solution works when .wrapper has any amount of children.

Just use the build-in feature of Angular CLI

ng update

to update to the latest version.

If you'd like to gather more information on the error and if the error occurs in the first few iterations, I suggest you run the experiment in CPU-only mode (no GPUs). The error message will be much more specific.

UCanAccess is a pure Java JDBC driver that allows us to read from and write to Access databases without using ODBC. It uses two other packages, Jackcess and HSQLDB, to perform these tasks. The following is a brief overview of how to get it set up.

Option 1: Using Maven

If your project uses Maven you can simply include UCanAccess via the following coordinates:

groupId: net.sf.ucanaccess
artifactId: ucanaccess

The following is an excerpt from pom.xml, you may need to update the <version> to get the most recent release:

  <dependencies>
    <dependency>
        <groupId>net.sf.ucanaccess</groupId>
        <artifactId>ucanaccess</artifactId>
        <version>4.0.4</version>
    </dependency>
  </dependencies>

Option 2: Manually adding the JARs to your project

As mentioned above, UCanAccess requires Jackcess and HSQLDB. Jackcess in turn has its own dependencies. So to use UCanAccess you will need to include the following components:

UCanAccess (ucanaccess-x.x.x.jar)
HSQLDB (hsqldb.jar, version 2.2.5 or newer)
Jackcess (jackcess-2.x.x.jar)
commons-lang (commons-lang-2.6.jar, or newer 2.x version)
commons-logging (commons-logging-1.1.1.jar, or newer 1.x version)

Fortunately, UCanAccess includes all of the required JAR files in its distribution file. When you unzip it you will see something like

ucanaccess-4.0.1.jar  
  /lib/
    commons-lang-2.6.jar  
    commons-logging-1.1.1.jar  
    hsqldb.jar  
    jackcess-2.1.6.jar

All you need to do is add all five (5) JARs to your project.

NOTE: Do not add loader/ucanload.jar to your build path if you are adding the other five (5) JAR files. The UcanloadDriver class is only used in special circumstances and requires a different setup. See the related answer here for details.

Eclipse: Right-click the project in Package Explorer and choose Build Path > Configure Build Path.... Click the "Add External JARs..." button to add each of the five (5) JARs. When you are finished your Java Build Path should look something like this

NetBeans: Expand the tree view for your project, right-click the "Libraries" folder and choose "Add JAR/Folder...", then browse to the JAR file.

After adding all five (5) JAR files the "Libraries" folder should look something like this:

IntelliJ IDEA: Choose File > Project Structure... from the main menu. In the "Libraries" pane click the "Add" (+) button and add the five (5) JAR files. Once that is done the project should look something like this:

That's it!

Now "U Can Access" data in .accdb and .mdb files using code like this

// assumes...
//     import java.sql.*;
Connection conn=DriverManager.getConnection(
        "jdbc:ucanaccess://C:/__tmp/test/zzz.accdb");
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT [LastName] FROM [Clients]");
while (rs.next()) {
    System.out.println(rs.getString(1));
}

Disclosure

At the time of writing this Q&A I had no involvement in or affiliation with the UCanAccess project; I just used it. I have since become a contributor to the project.

In Android Studio this works: Go to File->Settings->Editor->CodeStyle->Java. Under Wrapping and Braces uncheck "Comment at first Column" Then formatting shortcut will indent the comment lines as well.

Hopefully this helps someone out there.

For platform I was specifying "Any CPU", changed it to "AnyCPU" and that fixed the problem.

msbuild C:\Users\Project\Project.publishproj /p:Platform="AnyCPU"  /p:DeployOnBuild=true /p:PublishProfile=local /p:Configuration=Debug

If you look at your .csproj file you'll see the correct platform name to use.

you can use linkbutton for navigating to another section in the same page by using PostBackUrl="#Section2"

This is what you need:

 =NOT(ISERROR(MATCH(<cell in col A>,<column B>, 0)))  ## pseudo code

For the first cell of A, this would be:

 =NOT(ISERROR(MATCH(A2,$B$2:$B$5, 0)))

Enter formula (and drag down) as follows:

You will get:

You can use the visible selector:

http://api.jquery.com/visible-selector/

In windows version

you can find the log in the bottom of the IDE, click the "Gradle Console", and then choose the "Android Monitor". You will see a Droplistbox control which shows "Verbose" as a default value.

If you use log.v() . Verbose option is okay. if you use log.d(), just change it to Debug.

So when you run your emulator, you can catch your log from this window.

I'm using .NET Core 3.1.101 and the .csproj additions that worked for me were:

<PropertyGroup>
  <!-- Explicitly generate Assembly Info -->
  <GenerateAssemblyInfo>true</GenerateAssemblyInfo>
</PropertyGroup>

<ItemGroup>
  <AssemblyAttribute Include="System.Runtime.CompilerServices.InternalsVisibleToAttribute">
  <_Parameter1>MyProject.Tests</_Parameter1>
  </AssemblyAttribute>
</ItemGroup>

You need to create own PCH file
Add New file -> Other-> PCH file

Then add the path of this PCH file to your build setting->prefix header->path

($(SRCROOT)/filename.pch)

Remove column constraint: not null to null

ALTER TABLE test ALTER COLUMN column_01 DROP NOT NULL;

I am currently using Android Studio 1.4.

For importing and adding libraries, I used the following flow ->

1. Press **Alt+Ctr+Shift+S** or Go to **File --> Project** Structure to open up the Project Structure Dialog Box.

2. Click on **Modules** to which you want to link the JAR to and Go to the Dependency Tab.

3. Click on "**+**" Button to pop up Choose Library Dependency.

4. Search/Select the dependency and rebuild the project.

I used the above approach to import support v4 and v13 libraries.

I hope this is helpful and clears up the flow.

If you want to know the number of visitors (as is titled in the question) and not the number of pageviews, then you'll need to create a custom report.

Terminology

Google Analytics has changed the terminology they use within the reports. Now, visits is named "sessions" and unique visitors is named "users."

User - A unique person who has visited your website. Users may visit your website multiple times, and they will only be counted once.

Session - The number of different times that a visitor came to your site.

Pageviews - The total number of pages that a user has accessed.

Creating a Custom Report

1. To create a custom report, click on the "Customization" item in the left navigation menu, and then click on "Custom Reports".

2. The "Create Custom Report" page will open.
3. Enter a name for your report.
4. In the "Metric Groups" section, enter either "Users" or "Sessions" depending on what information you want to collect (see Terminology, above).
5. In the "Dimension Drilldowns" section, enter "Page".
6. Under "Filters" enter the individual page (exact) or group of pages (using regex) that you would like to see the data for.
7. Save the report and run it.

In chrome to set the value you need to do YYYY-MM-DD i guess because this worked : http://jsfiddle.net/HudMe/6/

So to make it work you need to set the date as 2012-10-01

MD5 is bad because of collision problems - two different passwords possibly generating the same md-5.

Sha-1 would be plenty secure for this. The reason you store the salted sha-1 version of the password is so that you the swerver do not keep the user's apassword on file, that they may be using with other people's servers. Otherwise, what difference does it make?

If the hacker steals your entire unencrypted database some how, the only thing a hashed salted password does is prevent him from impersonating the user for future signons - the hacker already has the data.

What good does it do the attacker to have the hashed value, if what your user inputs is a plain password?

And even if the hacker with future technology could generate a million sha-1 keys a second for a brute force attack, would your server handle a million logons a second for the hacker to test his keys? That's if you are letting the hacker try to logon with the salted sha-1 instead of a password like a normal logon.

The best bet is to limit bad logon attempts to some reasonable number - 25 for example, and then time the user out for a minute or two. And if the cumulative bady logon attempts hits 250 within 24 hours, shut the account access down and email the owner.

Well Heroku uses AWS in background, it all depends on the type of solution you need. If you are a core linux and devops guy you are not worried about creating vm from scratch like selecting ami choosing palcement options etc, you can go with AWS. If you want to do things on surface level without having those nettigrities you can go with heroku.

Here is a simple example, it will help you to get object key name.

var obj ={parts:{costPart:1000, salesPart: 2000}}; console.log(Object.keys(obj));

the output would be parts.

However, ngOptions provides some benefits such as reducing memory and increasing speed by not creating a new scope for each repeated instance. angular docs

Alternative solution is use ng-init directive. You can specify function that will be initialize your default data.

$scope.init = function(){
            angular.forEach($scope.units, function(item){
                if(item.id === $scope.data.unit){
                    $scope.data.unit = item;
                }
            });
        } 

See jsfiddle

Without reloading the page or refreshing the dom, history.pushState can do the job.
Add this method in your component or elsewhere to do that:

addParamsToLocation(params) {
  history.pushState(
    {},
    null,
    this.$route.path +
      '?' +
      Object.keys(params)
        .map(key => {
          return (
            encodeURIComponent(key) + '=' + encodeURIComponent(params[key])
          )
        })
        .join('&')
  )
}

So anywhere in your component, call addParamsToLocation({foo: 'bar'}) to push the current location with query params in the window.history stack.

To add query params to current location without pushing a new history entry, use history.replaceState instead.

Tested with Vue 2.6.10 and Nuxt 2.8.1.

Be careful with this method!
Vue Router don't know that url has changed, so it doesn't reflect url after pushState.

A website is now online with all the TSDoc syntax available (and that's awesome): https://tsdoc.org/

For reference, old answer:

The right syntax is now the one used by TSDoc. It will allow you to have your comments understood by Visual Studio Code or other documentation tools.

Note: you should not use JSDoc, as explained on TSDoc main page: Why can't JSDoc be the standard? Unfortunately, the JSDoc grammar is not rigorously specified but rather inferred from the behavior of a particular implementation. The majority of the standard JSDoc tags are preoccupied with providing type annotations for plain JavaScript, which is an irrelevant concern for a strongly-typed language such as TypeScript. TSDoc addresses these limitations while also tackling a more sophisticated set of goals.

How about str.split()? Nothing to import.

import os

image_names = [f for f in os.listdir(path) if len(f.split('.jpg')) == 2]

A[A==NDV]=numpy.nan

A==NDV will produce a boolean array that can be used as an index for A

You have a good example here (Array of Function pointers), with the syntax detailed.

int sum(int a, int b);
int subtract(int a, int b);
int mul(int a, int b);
int div(int a, int b);

int (*p[4]) (int x, int y);

int main(void)
{
  int result;
  int i, j, op;

  p[0] = sum; /* address of sum() */
  p[1] = subtract; /* address of subtract() */
  p[2] = mul; /* address of mul() */
  p[3] = div; /* address of div() */
[...]

To call one of those function pointers:

result = (*p[op]) (i, j); // op being the index of one of the four functions

It's very easy and convenient to change font size from storyboard, and you can instantly see the result of the change.

Actually, it's also very easy to change other font attributes on storyboard too, like style, font family, etc.

Consider this:

function group1k(s) {
    return (""+s)
        .replace(/(\d+)(\d{3})(\d{3})$/  ,"$1 $2 $3" )
        .replace(/(\d+)(\d{3})$/         ,"$1 $2"    )
        .replace(/(\d+)(\d{3})(\d{3})\./ ,"$1 $2 $3.")
        .replace(/(\d+)(\d{3})\./        ,"$1 $2."   )
    ;
}

It's a quick solution for anything under 999.999.999, which is usually enough. I know the drawbacks and I'm not saying this is the ultimate weapon - but it's just as fast as the others above and I find this one more readable. If you don't need decimals you can simplify it even more:

function group1k(s) {
    return (""+s)
        .replace(/(\d+)(\d{3})(\d{3})$/ ,"$1 $2 $3")
        .replace(/(\d+)(\d{3})$/        ,"$1 $2"   )
    ;
}

Isn't it handy.

Solution from typescript interfaces reference:

interface ClockConstructor {
    new (hour: number, minute: number): ClockInterface;
}
interface ClockInterface {
    tick();
}

function createClock(ctor: ClockConstructor, hour: number, minute: number): ClockInterface {
    return new ctor(hour, minute);
}

class DigitalClock implements ClockInterface {
    constructor(h: number, m: number) { }
    tick() {
        console.log("beep beep");
    }
}
class AnalogClock implements ClockInterface {
    constructor(h: number, m: number) { }
    tick() {
        console.log("tick tock");
    }
}

let digital = createClock(DigitalClock, 12, 17);
let analog = createClock(AnalogClock, 7, 32);

So the previous example becomes:

interface AnimalConstructor {
    new (): Animal;
}

class Animal {
    constructor() {
        console.log("Animal");
    }
}

class Penguin extends Animal {
    constructor() {
        super();
        console.log("Penguin");
    }
}

class Lion extends Animal {
    constructor() {
        super();
        console.log("Lion");
    }
}

class Zoo {
    AnimalClass: AnimalConstructor // AnimalClass can be 'Lion' or 'Penguin'

    constructor(AnimalClass: AnimalConstructor) {
        this.AnimalClass = AnimalClass
        let Hector = new AnimalClass();
    }
}

Rucksack is brilliant, but you don't necessarily have to resort to build tools like Gulp or Grunt etc.

I made a demo using CSS Custom Properties (CSS Variables) to easily control the min and max font sizes.

Like so:

* {
  /* Calculation */
  --diff: calc(var(--max-size) - var(--min-size));
  --responsive: calc((var(--min-size) * 1px) + var(--diff) * ((100vw - 420px) / (1200 - 420))); /* Ranges from 421px to 1199px */
}

h1 {
  --max-size: 50;
  --min-size: 25;
  font-size: var(--responsive);
}

h2 {
  --max-size: 40;
  --min-size: 20;
  font-size: var(--responsive);
}

If you are installing from an ISO file by mounting it on a Virtual Drive, Just copy the files from the Virtual Drive to your hard disk. Run the installer, it will definitely work. I have solved my problem.

A solution would be to declare your key as nvarchar(20).

One method is to add a new event listener that calls e.stopImmediatePropagation().

<input type='text' minlength=3 /><br />

if browser supports html5,

it will automatical be validate attributes(minlength) in tag

but Safari(iOS) doesn't working

You are looking to see if a single value is in an array. Use in_array.

However note that case is important, as are any leading or trailing spaces. Use var_dump to find out the length of the strings too, and see if they fit.

For Xampp Users

1. Go to C:\xampp\phpMyAdmin\libraries
2. Open config.default.php
3. Search for $cfg['ExecTimeLimit'] = 300;
4. Change to the Value 300 to 0 or set a larger value
5. Save the file and restart the server
6. OR Set the ini_set('MAX_EXECUTION_TIME', '-1'); at the beginning of your script you can add.

You might want to use TRUNC function on your column when comparing with string format, so it compares only till seconds, not milliseconds.

SELECT * FROM <table_name> WHERE id = 1 
AND TRUNC(usagetime, 'SS') = '2012-09-03 08:03:06';

If you wanted to truncate upto minutes, hours, etc. that is also possible, just use appropriate notation instead of 'SS':

hour ('HH'), minute('MI'), year('YEAR' or 'YYYY'), month('MONTH' or 'MM'), Day ('DD')

Here is one approach you can use which would work even if both dictonaries don't have same keys:

d1 = {'a':'test','b':'btest','d':'dreg'}
d2 = {'a':'cool','b':'main','c':'clear'}

d = {}

for key in set(d1.keys() + d2.keys()):
    try:
        d.setdefault(key,[]).append(d1[key])        
    except KeyError:
        pass

    try:
        d.setdefault(key,[]).append(d2[key])          
    except KeyError:
        pass

print d

This would generate below input:

{'a': ['test', 'cool'], 'c': ['clear'], 'b': ['btest', 'main'], 'd': ['dreg']}

My solution is:

public static Bitmap loadBitmapFromView(Context context, View v) {
    DisplayMetrics dm = context.getResources().getDisplayMetrics(); 
    v.measure(MeasureSpec.makeMeasureSpec(dm.widthPixels, MeasureSpec.EXACTLY),
            MeasureSpec.makeMeasureSpec(dm.heightPixels, MeasureSpec.EXACTLY));
    v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());
    Bitmap returnedBitmap = Bitmap.createBitmap(v.getMeasuredWidth(),
            v.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
    Canvas c = new Canvas(returnedBitmap);
    v.draw(c);

    return returnedBitmap;
}

and

public void takeScreen() {
    Bitmap bitmap = ImageUtils.loadBitmapFromView(this, view); //get Bitmap from the view
    String mPath = Environment.getExternalStorageDirectory() + File.separator + "screen_" + System.currentTimeMillis() + ".jpeg";
    File imageFile = new File(mPath);
    OutputStream fout = null;
    try {
        fout = new FileOutputStream(imageFile);
        bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fout);
        fout.flush();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        fout.close();
    }
}

Images are saved in the external storage folder.

This worked for me in Xamarin.iOS / Monotouch. Change the keyboard button to Next, pass the control to the next UITextField and hide the keyboard after the last UITextField.

private void SetShouldReturnDelegates(IEnumerable<UIView> subViewsToScout )
{
  foreach (var item in subViewsToScout.Where(item => item.GetType() == typeof (UITextField)))
  {
    (item as UITextField).ReturnKeyType = UIReturnKeyType.Next;
    (item as UITextField).ShouldReturn += (textField) =>
    {
        nint nextTag = textField.Tag + 1;
        var nextResponder = textField.Superview.ViewWithTag(nextTag);
        if (null != nextResponder)
            nextResponder.BecomeFirstResponder();
        else
            textField.Superview.EndEditing(true); 
            //You could also use textField.ResignFirstResponder(); 

        return false; // We do not want UITextField to insert line-breaks.
    };
  }
}

Inside the ViewDidLoad you'll have:

If your TextFields haven't a Tag set it now:

txtField1.Tag = 0;
txtField2.Tag = 1;
txtField3.Tag = 2;
//...

and just the call

SetShouldReturnDelegates(yourViewWithTxtFields.Subviews.ToList());
//If you are not sure of which view contains your fields you can also call it in a safer way:
SetShouldReturnDelegates(txtField1.Superview.Subviews.ToList());
//You can also reuse the same method with different containerViews in case your UITextField are under different views.

$string = ' Test me more ';
preg_match('/\b\w+\b/i', $string, $result); // Test
echo $result;

/* You could use [a-zA-Z]+ instead of \w+ if wanted only alphabetical chars. */
$string = ' Test me more ';
preg_match('/\b[a-zA-Z]+\b/i', $string, $result); // Test
echo $result;

I had similar issue with Release build. Debug build was compiling without any issues. Turns out that the problem was caused by OneDrive. Most likely one could experience similar issues with any backed-up drive or cloud service.

I cleaned everything as per Avi Turner's great answer.

In addition, I manually deleted the \obj\Release -folder from my OneDrive folder and also logged to OneDrive with a browser and deleted the folder there also to prevent OneDrive from loading the cloud version back when compiling.
After that rebuilt and everything worked as should.

My experience with making something very simple in PhoneGap+jQuery Mobile was fine. I was able to do it quickly for iOS. However, it didn't work on my Android phones without making some changes. The project was a very simple app to take pictures and post them to a web site. And at the end of the day it felt "clunky" compared to a true native app.

I don't believe there will ever be easy cross platform development. I think the browser is as close as you will get. By choosing something like PhoneGap I think you are just trading one set of pain points for a different set of pain points.

My solution

• Assuming that form id = "my_form_id"
• It detects the form method and form action from HTML

jQuery code

$('#my_form_id').on('submit', function(e) {
    e.preventDefault();
    var formData = new FormData($(this)[0]);
    var msg_error = 'An error has occured. Please try again later.';
    var msg_timeout = 'The server is not responding';
    var message = '';
    var form = $('#my_form_id');
    $.ajax({
        data: formData,
        async: false,
        cache: false,
        processData: false,
        contentType: false,
        url: form.attr('action'),
        type: form.attr('method'),
        error: function(xhr, status, error) {
            if (status==="timeout") {
                alert(msg_timeout);
            } else {
                alert(msg_error);
            }
        },
        success: function(response) {
            alert(response);
        },
        timeout: 7000
    });
});

Superclass variable = new subclass object();
This just creates an object of type subclass, but assigns it to the type superclass. All the subclasses' data is created etc, but the variable cannot access the subclasses data/functions. In other words, you cannot call any methods or access data specific to the subclass, you can only access the superclasses stuff.

However, you can cast Superclassvariable to the Subclass and use its methods/data.

If you mean VB 6, that would be Private Sub Class_Initialize().

http://msdn.microsoft.com/en-us/library/55yzhfb2(VS.80).aspx

If you mean VB.NET it is Public Sub New() or Shared Sub New().

I had a column that did not allow nulls and I was inserting a null value.

smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
smtp.Credentials = new NetworkCredential(fromAddress, fromPassword);
smtp.Timeout = 20000;

Comparison of different approaches to set exact image sizes in pixels

This answer will focus on:

• savefig
• setting the size in pixels

Here is a quick comparison of some of the approaches I've tried with images showing what the give.

Baseline example without trying to set the image dimensions

Just to have a comparison point:

base.py

#!/usr/bin/env python3

import sys

import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl

fig, ax = plt.subplots()
print('fig.dpi = {}'.format(fig.dpi))
print('fig.get_size_inches() = ' + str(fig.get_size_inches())
t = np.arange(-10., 10., 1.)
plt.plot(t, t, '.')
plt.plot(t, t**2, '.')
ax.text(0., 60., 'Hello', fontdict=dict(size=25))
plt.savefig('base.png', format='png')

run:

./base.py
identify base.png

outputs:

fig.dpi = 100.0
fig.get_size_inches() = [6.4 4.8]
base.png PNG 640x480 640x480+0+0 8-bit sRGB 13064B 0.000u 0:00.000

My best approach so far: plt.savefig(dpi=h/fig.get_size_inches()[1] height-only control

I think this is what I'll go with most of the time, as it is simple and scales:

get_size.py

#!/usr/bin/env python3

import sys

import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl

height = int(sys.argv[1])
fig, ax = plt.subplots()
t = np.arange(-10., 10., 1.)
plt.plot(t, t, '.')
plt.plot(t, t**2, '.')
ax.text(0., 60., 'Hello', fontdict=dict(size=25))
plt.savefig(
    'get_size.png',
    format='png',
    dpi=height/fig.get_size_inches()[1]
)

run:

./get_size.py 431

outputs:

get_size.png PNG 574x431 574x431+0+0 8-bit sRGB 10058B 0.000u 0:00.000

and

./get_size.py 1293

outputs:

main.png PNG 1724x1293 1724x1293+0+0 8-bit sRGB 46709B 0.000u 0:00.000

I tend to set just the height because I'm usually most concerned about how much vertical space the image is going to take up in the middle of my text.

plt.savefig(bbox_inches='tight' changes image size

I always feel that there is too much white space around images, and tended to add bbox_inches='tight' from: Removing white space around a saved image in matplotlib

However, that works by cropping the image, and you won't get the desired sizes with it.

Instead, this other approach proposed in the same question seems to work well:

plt.tight_layout(pad=1)
plt.savefig(...

which gives the exact desired height for height equals 431:

Fixed height, set_aspect, automatically sized width and small margins

Ermmm, set_aspect messes things up again and prevents plt.tight_layout from actually removing the margins...

Asked at: How to obtain a fixed height in pixels, fixed data x/y aspect ratio and automatically remove remove horizontal whitespace margin in Matplotlib?

plt.savefig(dpi=h/fig.get_size_inches()[1] + width control

If you really need a specific width in addition to height, this seems to work OK:

width.py

#!/usr/bin/env python3

import sys

import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl

h = int(sys.argv[1])
w = int(sys.argv[2])
fig, ax = plt.subplots()
wi, hi = fig.get_size_inches()
fig.set_size_inches(hi*(w/h), hi)
t = np.arange(-10., 10., 1.)
plt.plot(t, t, '.')
plt.plot(t, t**2, '.')
ax.text(0., 60., 'Hello', fontdict=dict(size=25))
plt.savefig(
    'width.png',
    format='png',
    dpi=h/hi
)

run:

./width.py 431 869

output:

width.png PNG 869x431 869x431+0+0 8-bit sRGB 10965B 0.000u 0:00.000

and for a small width:

./width.py 431 869

output:

width.png PNG 211x431 211x431+0+0 8-bit sRGB 6949B 0.000u 0:00.000

So it does seem that fonts are scaling correctly, we just get some trouble for very small widths with labels getting cut off, e.g. the 100 on the top left.

I managed to work around those with Removing white space around a saved image in matplotlib

plt.tight_layout(pad=1)

which gives:

width.png PNG 211x431 211x431+0+0 8-bit sRGB 7134B 0.000u 0:00.000

From this, we also see that tight_layout removes a lot of the empty space at the top of the image, so I just generally always use it.

Fixed magic base height, dpi on fig.set_size_inches and plt.savefig(dpi= scaling

I believe that this is equivalent to the approach mentioned at: https://stackoverflow.com/a/13714720/895245

magic.py

#!/usr/bin/env python3

import sys

import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl

magic_height = 300
w = int(sys.argv[1])
h = int(sys.argv[2])
dpi = 80
fig, ax = plt.subplots(dpi=dpi)
fig.set_size_inches(magic_height*w/(h*dpi), magic_height/dpi)
t = np.arange(-10., 10., 1.)
plt.plot(t, t, '.')
plt.plot(t, t**2, '.')
ax.text(0., 60., 'Hello', fontdict=dict(size=25))
plt.savefig(
    'magic.png',
    format='png',
    dpi=h/magic_height*dpi,
)

run:

./magic.py 431 231

outputs:

magic.png PNG 431x231 431x231+0+0 8-bit sRGB 7923B 0.000u 0:00.000

And to see if it scales nicely:

./magic.py 1291 693

outputs:

magic.png PNG 1291x693 1291x693+0+0 8-bit sRGB 25013B 0.000u 0:00.000

So we see that this approach also does work well. The only problem I have with it is that you have to set that magic_height parameter or equivalent.

Fixed DPI + set_size_inches

This approach gave a slightly wrong pixel size, and it makes it is hard to scale everything seamlessly.

set_size_inches.py

#!/usr/bin/env python3

import sys

import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl

w = int(sys.argv[1])
h = int(sys.argv[2])
fig, ax = plt.subplots()
fig.set_size_inches(w/fig.dpi, h/fig.dpi)
t = np.arange(-10., 10., 1.)
plt.plot(t, t, '.')
plt.plot(t, t**2, '.')
ax.text(
    0,
    60.,
    'Hello',
    # Keep font size fixed independently of DPI.
    # https://stackoverflow.com/questions/39395616/matplotlib-change-figsize-but-keep-fontsize-constant
    fontdict=dict(size=10*h/fig.dpi),
)
plt.savefig(
    'set_size_inches.png',
    format='png',
)

run:

./set_size_inches.py 431 231

outputs:

set_size_inches.png PNG 430x231 430x231+0+0 8-bit sRGB 8078B 0.000u 0:00.000

so the height is slightly off, and the image:

The pixel sizes are also correct if I make it 3 times larger:

./set_size_inches.py 1291 693

outputs:

set_size_inches.png PNG 1291x693 1291x693+0+0 8-bit sRGB 19798B 0.000u 0:00.000

We understand from this however that for this approach to scale nicely, you need to make every DPI-dependant setting proportional to the size in inches.

In the previous example, we only made the "Hello" text proportional, and it did retain its height between 60 and 80 as we'd expect. But everything for which we didn't do that, looks tiny, including:

• line width of axes
• tick labels
• point markers

SVG

I could not find how to set it for SVG images, my approaches only worked for PNG e.g.:

get_size_svg.py

#!/usr/bin/env python3

import sys

import numpy as np
import matplotlib.pyplot as plt
import matplotlib as mpl

height = int(sys.argv[1])
fig, ax = plt.subplots()
t = np.arange(-10., 10., 1.)
plt.plot(t, t, '.')
plt.plot(t, t**2, '.')
ax.text(0., 60., 'Hello', fontdict=dict(size=25))
plt.savefig(
    'get_size_svg.svg',
    format='svg',
    dpi=height/fig.get_size_inches()[1]
)

run:

./get_size_svg.py 431

and the generated output contains:

<svg height="345.6pt" version="1.1" viewBox="0 0 460.8 345.6" width="460.8pt"

and identify says:

get_size_svg.svg SVG 614x461 614x461+0+0 8-bit sRGB 17094B 0.000u 0:00.000

and if I open it in Chromium 86 the browser debug tools mouse image hover confirm that height as 460.79.

But of course, since SVG is a vector format, everything should in theory scale, so you can just convert to any fixed sized format without loss of resolution, e.g.:

inkscape -h 431 get_size_svg.svg -b FFF -e get_size_svg.png

gives the exact height:

I use Inkscape instead of Imagemagick's convert here because you need to mess with -density as well to get sharp SVG resizes with ImageMagick:

• https://superuser.com/questions/598849/imagemagick-convert-how-to-produce-sharp-resized-png-files-from-svg-files/1602059#1602059
• How to convert a SVG to a PNG with ImageMagick?

And setting <img height="" on the HTML should also just work for the browser.

Tested on matplotlib==3.2.2.

following should be your right solution

As an addition to @ANisus' answer...

below is some information from the "Go in action" book, which I think is worth mentioning:

Difference between nil & empty slices

If we think of a slice like this:

[pointer] [length] [capacity]

then:

nil slice:   [nil][0][0]
empty slice: [addr][0][0] // points to an address

nil slice

They’re useful when you want to represent a slice that doesn’t exist, such as when an exception occurs in a function that returns a slice.

// Create a nil slice of integers.
var slice []int

empty slice

Empty slices are useful when you want to represent an empty collection, such as when a database query returns zero results.

// Use make to create an empty slice of integers.
slice := make([]int, 0)

// Use a slice literal to create an empty slice of integers.
slice := []int{}

Regardless of whether you’re using a nil slice or an empty slice, the built-in functions append, len, and cap work the same.

Go playground example:

package main

import (
    "fmt"
)

func main() {

    var nil_slice []int
    var empty_slice = []int{}

    fmt.Println(nil_slice == nil, len(nil_slice), cap(nil_slice))
    fmt.Println(empty_slice == nil, len(empty_slice), cap(empty_slice))

}

prints:

true 0 0
false 0 0

Try:

from p in db.Products
where !theBadCategories.Contains(p.Category)
select p;

What's the SQL query you want to translate into a Linq query?

You can split it at the backslashes, and take the next-to-last one with negative array indexing to get just the grandparent directory name.

($scriptpath -split '\\')[-2]

You have to double the backslash to escape it in the regex.

To get the entire path:

($path -split '\\')[0..(($path -split '\\').count -2)] -join '\'

And, looking at the parameters for split-path, it takes the path as pipeline input, so:

$rootpath = $scriptpath | split-path -parent | split-path -parent

public void setUp() throws Exception {

 System.setProperty("webdriver.chrome.driver","Absolute path of Chrome driver");

 driver =new ChromeDriver();
 baseUrl = "URL/";

    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
  }

Log4JDBC is a nice solution which prints the exact SQL going to the database with parameters in place rather than the most popular answer here which does not do this. One major convenience of this is that you can copy the SQL straight to your DB front-end and execute as is.

http://log4jdbc.sourceforge.net/

https://code.google.com/p/log4jdbc-remix/

The latter also outputs a tabular representation of query results.

Sample Output showing generated SQL with params in place together with result set table from query:

Update 2016

Most recently I have now been using log4jdbc-log4j2 (https://code.google.com/archive/p/log4jdbc-log4j2/ ) with SLF4j and logback. Maven dependencies required for my set-up are as below:

<dependency>
    <groupId>org.bgee.log4jdbc-log4j2</groupId>
    <artifactId>log4jdbc-log4j2-jdbc4.1</artifactId>
    <version>1.16</version>
</dependency>
<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>${slf4j.version}</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-core</artifactId>
    <version>${logback.version}</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>$logback.version}</version>
</dependency>

The Driver and DB Urls then look like:

database.driver.class=net.sf.log4jdbc.sql.jdbcapi.DriverSpy
database.url=jdbc:log4jdbc:hsqldb:mem:db_name #Hsql
#database.url=jdbc:log4jdbc:mysql://localhost:3306/db_name 

My logback.xml configuration file looks like the below: this outputs all SQL statements with parameters plus the resultset tables for all queries.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
            </pattern>
        </encoder>
    </appender>

    <logger name="jdbc.audit" level="ERROR" />
    <logger name="jdbc.connection" level="ERROR" />
    <logger name="jdbc.sqltiming" level="ERROR" />
    <logger name="jdbc.resultset" level="ERROR" />

    <!-- UNCOMMENT THE BELOW TO HIDE THE RESULT SET TABLE OUTPUT -->
    <!--<logger name="jdbc.resultsettable" level="ERROR" /> -->

    <root level="debug">
        <appender-ref ref="STDOUT" />
    </root>
</configuration>

Finally, I had to create a file named log4jdbc.log4j2.properties at the root of the classpath e.g. src/test/resources or src/main/resources in a Mevn project. This file has one line which is the below:

log4jdbc.spylogdelegator.name=net.sf.log4jdbc.log.slf4j.Slf4jSpyLogDelegator

The above will depend on your logging library. See the docs at https://code.google.com/archive/p/log4jdbc-log4j2 for further info

I think the following code is close to what you want

x    <- c(0.1, 0.2, 0.3, 0.4, 0.5)
y    <- c(1, 2, 3, 4, 5)
zfun <- function(a,b) {a*b * ( 0.9 + 0.2*runif(a*b) )}
z    <- outer(x, y, FUN="zfun")

It gives data like this (note that x and y are both increasing)

> x
[1] 0.1 0.2 0.3 0.4 0.5
> y
[1] 1 2 3 4 5
> z
          [,1]      [,2]      [,3]      [,4]      [,5]

As much as I know there is no annotation like this. The best way is to use reflection as some of the others suggested. Look at this post:
How do I test a class that has private methods, fields or inner classes?

You should only watch out on testing the exception outcome of the method. For example: if u expect an IllegalArgumentException, but instead you'll get "null" (Class:java.lang.reflect.InvocationTargetException).
A colegue of mine proposed using the powermock framework for these situations, but I haven't tested it yet, so no idea what exactly it can do. Although I have used the Mockito framework that it is based upon and thats a good framework too (but I think doesn't solve the private method exception issue).

It's a great idea though having the @PublicForTests annotation.

Cheers!

@RequestMapping(value = "/testonly", method = { RequestMethod.GET, RequestMethod.POST })
public ModelAndView listBooksPOST(@ModelAttribute("booksFilter") BooksFilter filter,
        @RequestParam(required = false) String parameter1,
        @RequestParam(required = false) String parameter2, 
        BindingResult result, HttpServletRequest request) 
        throws ParseException {

    LONG CODE and SAME LONG CODE with a minor difference
}

if @RequestParam(required = true) then you must pass parameter1,parameter2

Use BindingResult and request them based on your conditions.

The Other way

@RequestMapping(value = "/books", method = RequestMethod.GET)
public ModelAndView listBooks(@ModelAttribute("booksFilter") BooksFilter filter,  
    two @RequestParam parameters, HttpServletRequest request) throws ParseException {

    myMethod();

}


@RequestMapping(value = "/books", method = RequestMethod.POST)
public ModelAndView listBooksPOST(@ModelAttribute("booksFilter") BooksFilter filter, 
        BindingResult result) throws ParseException {

    myMethod();

    do here your minor difference
}

private returntype myMethod(){
    LONG CODE
}

Very simple , using Alt fragment

Lets take an example of sequence diagram for an ATM machine.Let's say here you want

IF card inserted is valid then prompt "Enter Pin"....ELSE prompt "Invalid Pin"

Then here is the sequence diagram for the same

Hope this helps!

I want to add my 2 cents. I am far from being a database expert, but I've recently read up a bit on this topic; enough for me to try and give an ELI5. So, here's may layman's explanation.

I understand it as such that an index is like a mini-mirror of your table, pretty much like an associative array. If you feed it with a matching key then you can just jump to that row in one "command".

But if you didn't have that index / array, the query interpreter must use a for-loop to go through all rows and check for a match (the full-table scan).

Having an index has the "downside" of extra storage (for that mini-mirror), in exchange for the "upside" of looking up content faster.

Note that (in dependence of your db engine) creating primary, foreign or unique keys automatically sets up a respective index as well. That same principle is basically why and how those keys work.

You dont need to give column names manually in xaml. Just set AutoGenerateColumns property to true and your list will be automatically binded to DataGrid. refer code. XAML Code:

<Grid>
    <DataGrid x:Name="MyDatagrid" AutoGenerateColumns="True" Height="447" HorizontalAlignment="Left" Margin="20,85,0,0" VerticalAlignment="Top" Width="799"  ItemsSource="{Binding Path=ListTest, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"  CanUserAddRows="False"> </Grid>

C#

Public Class Test 
{
    public string m_field1_Test{get;set;}
    public string m_field2_Test { get; set; }
    public Test()
    {
        m_field1_Test = "field1";
        m_field2_Test = "field2";
    }
    public MainWindow()
    {

        listTest = new List<Test>();

        for (int i = 0; i < 10; i++)
        {
            obj = new Test();
            listTest.Add(obj);

        }

        this.MyDatagrid.ItemsSource = ListTest;

        InitializeComponent();

    }

If the above solution didn't work for you, you can use import { withRouter } from 'react-router-dom';

Using this you can export your child class as -

class MyApp extends Component{
    // your code
}

export default withRouter(MyApp);

And your class with Router -

// your code
<Router>
      ...
      <Route path="/myapp" component={MyApp} />
      // or if you are sending additional fields
      <Route path="/myapp" component={() =><MyApp process={...} />} />
<Router>

Install python version 3.6+ and open you text editor or ide write sample code like this:

from tkinter import *

root = Tk()
root.title("Answer")

root.mainloop()

If you just want to suppress warnings from a function, you can add an @ sign in front:

<?php @function_that_i_dont_want_to_see_errors_from(parameters); ?>

Two-stage authentication is not supported with IIS7 Integrated mode. Authentication is now modularized, so rather than IIS performing authentication followed by asp.net performing authentication, it all happens at the same time.

You can either:

1. Change the app domain to be in IIS6 classic mode...
2. Follow this example (old link) of how to fake two-stage authentication with IIS7 integrated mode.
3. Use Helicon Ape and mod_auth to provide basic authentication

You can iterate over the index values if your dataframe has already been created.

df = df.groupby('l_customer_id_i').agg(lambda x: ','.join(x))
for name in df.index:
    print name
    print df.loc[name]

With Unicode we can do it easily,but if want to change color of bullet, I tried with colored bullet image and set it as drawable left and it worked

<TextView     
    android:text="Hello bullet"
    android:drawableLeft="@drawable/bulleticon" >
</TextView>

A robust Javascript library for capturing keyboard input and key combinations entered. It has no dependencies.

http://jaywcjlove.github.io/hotkeys/

hotkeys('ctrl+a,ctrl+b,r,f', function(event,handler){
    switch(handler.key){
        case "ctrl+a":alert('you pressed ctrl+a!');break;
        case "ctrl+b":alert('you pressed ctrl+b!');break;
        case "r":alert('you pressed r!');break;
        case "f":alert('you pressed f!');break;
    }
});

hotkeys understands the following modifiers: ?, shift, option, ?, alt, ctrl, control, command, and ?.

The following special keys can be used for shortcuts: backspace, tab, clear, enter, return, esc, escape, space, up, down, left, right, home, end, pageup, pagedown, del, delete and f1 through f19.

This is called context manager and I just want to add that similar approaches exist for other programming languages. Comparing them could be helpful in understanding the context manager in python. Basically, a context manager is used when we are dealing with some resources (file, network, database) that need to be initialized and at some point, tear downed (disposed). In Java 7 and above we have automatic resource management that takes the form of:

//Java code
try (Session session = new Session())
{
  // do stuff
}

Note that Session needs to implement AutoClosable or one of its (many) sub-interfaces.

In C#, we have using statements for managing resources that takes the form of:

//C# code
using(Session session = new Session())
{
  ... do stuff.
}

In which Session should implement IDisposable.

In python, the class that we use should implement __enter__ and __exit__. So it takes the form of:

#Python code
with Session() as session:
    #do stuff

And as others pointed out, you can always use try/finally statement in all the languages to implement the same mechanism. This is just syntactic sugar.

• gulp-clean deprecated for gulp-rimraf
• gulp-rimraf deprecated in favor of delete-files-folders

When you want to delete files and folders using del, you should append /** for recursive deletion.

gulp.task('clean', function () {

});

Crazy idea...

You could play around with some pseudo elements, and create up/down arrows of css content hex codes. The only challange will be to precise the positioning of the arrow, but it may work:

1. You need to be able to read code written by people who have different style and best practices opinions than you.

2. If you're only using cout, nobody gets confused. But when you have lots of namespaces flying around and you see this class and you aren't exactly sure what it does, having the namespace explicit acts as a comment of sorts. You can see at first glance, "oh, this is a filesystem operation" or "that's doing network stuff".

OCR which stands for Optical Character Recognition is a computer vision technique used to identify the different types of handwritten digits that are used in common mathematics. To perform OCR in OpenCV we will use the KNN algorithm which detects the nearest k neighbors of a particular data point and then classifies that data point based on the class type detected for n neighbors.

Data Used

This data contains 5000 handwritten digits where there are 500 digits for every type of digit. Each digit is of 20×20 pixel dimensions. We will split the data such that 250 digits are for training and 250 digits are for testing for every class.

Below is the implementation.

Output

91.64

Well, I decided to workout myself on my question to solve the above problem. What I wanted is to implement a simple OCR using KNearest or SVM features in OpenCV. And below is what I did and how. (it is just for learning how to use KNearest for simple OCR purposes).

1) My first question was about letter_recognition.data file that comes with OpenCV samples. I wanted to know what is inside that file.

It contains a letter, along with 16 features of that letter.

And this SOF helped me to find it. These 16 features are explained in the paper Letter Recognition Using Holland-Style Adaptive Classifiers. (Although I didn't understand some of the features at the end)

2) Since I knew, without understanding all those features, it is difficult to do that method. I tried some other papers, but all were a little difficult for a beginner.

So I just decided to take all the pixel values as my features. (I was not worried about accuracy or performance, I just wanted it to work, at least with the least accuracy)

I took the below image for my training data:

(I know the amount of training data is less. But, since all letters are of the same font and size, I decided to try on this).

To prepare the data for training, I made a small code in OpenCV. It does the following things:

1. It loads the image.
2. Selects the digits (obviously by contour finding and applying constraints on area and height of letters to avoid false detections).
3. Draws the bounding rectangle around one letter and wait for key press manually. This time we press the digit key ourselves corresponding to the letter in the box.
4. Once the corresponding digit key is pressed, it resizes this box to 10x10 and saves all 100 pixel values in an array (here, samples) and corresponding manually entered digit in another array(here, responses).
5. Then save both the arrays in separate .txt files.

At the end of the manual classification of digits, all the digits in the training data (train.png) are labeled manually by ourselves, image will look like below:

Below is the code I used for the above purpose (of course, not so clean):

import sys

import numpy as np
import cv2

im = cv2.imread('pitrain.png')
im3 = im.copy()

gray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
blur = cv2.GaussianBlur(gray,(5,5),0)
thresh = cv2.adaptiveThreshold(blur,255,1,1,11,2)

#################      Now finding Contours         ###################

contours,hierarchy = cv2.findContours(thresh,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)

samples =  np.empty((0,100))
responses = []
keys = [i for i in range(48,58)]

for cnt in contours:
    if cv2.contourArea(cnt)>50:
        [x,y,w,h] = cv2.boundingRect(cnt)
        
        if  h>28:
            cv2.rectangle(im,(x,y),(x+w,y+h),(0,0,255),2)
            roi = thresh[y:y+h,x:x+w]
            roismall = cv2.resize(roi,(10,10))
            cv2.imshow('norm',im)
            key = cv2.waitKey(0)

            if key == 27:  # (escape to quit)
                sys.exit()
            elif key in keys:
                responses.append(int(chr(key)))
                sample = roismall.reshape((1,100))
                samples = np.append(samples,sample,0)

responses = np.array(responses,np.float32)
responses = responses.reshape((responses.size,1))
print "training complete"

np.savetxt('generalsamples.data',samples)
np.savetxt('generalresponses.data',responses)

Now we enter in to training and testing part.

For the testing part, I used the below image, which has the same type of letters I used for the training phase.

For training we do as follows:

1. Load the .txt files we already saved earlier
2. create an instance of the classifier we are using (it is KNearest in this case)
3. Then we use KNearest.train function to train the data

For testing purposes, we do as follows:

1. We load the image used for testing
2. process the image as earlier and extract each digit using contour methods
3. Draw a bounding box for it, then resize it to 10x10, and store its pixel values in an array as done earlier.
4. Then we use KNearest.find_nearest() function to find the nearest item to the one we gave. ( If lucky, it recognizes the correct digit.)

I included last two steps (training and testing) in single code below:

import cv2
import numpy as np

#######   training part    ############### 
samples = np.loadtxt('generalsamples.data',np.float32)
responses = np.loadtxt('generalresponses.data',np.float32)
responses = responses.reshape((responses.size,1))

model = cv2.KNearest()
model.train(samples,responses)

############################# testing part  #########################

im = cv2.imread('pi.png')
out = np.zeros(im.shape,np.uint8)
gray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
thresh = cv2.adaptiveThreshold(gray,255,1,1,11,2)

contours,hierarchy = cv2.findContours(thresh,cv2.RETR_LIST,cv2.CHAIN_APPROX_SIMPLE)

for cnt in contours:
    if cv2.contourArea(cnt)>50:
        [x,y,w,h] = cv2.boundingRect(cnt)
        if  h>28:
            cv2.rectangle(im,(x,y),(x+w,y+h),(0,255,0),2)
            roi = thresh[y:y+h,x:x+w]
            roismall = cv2.resize(roi,(10,10))
            roismall = roismall.reshape((1,100))
            roismall = np.float32(roismall)
            retval, results, neigh_resp, dists = model.find_nearest(roismall, k = 1)
            string = str(int((results[0][0])))
            cv2.putText(out,string,(x,y+h),0,1,(0,255,0))

cv2.imshow('im',im)
cv2.imshow('out',out)
cv2.waitKey(0)

And it worked, below is the result I got:

Here it worked with 100% accuracy. I assume this is because all the digits are of the same kind and the same size.

But anyway, this is a good start to go for beginners (I hope so).

Java does not support multiple inheritance , multipath and hybrid inheritance because of ambiguity problem:

 Scenario for multiple inheritance: Let us take class A , class B , class C. class A has alphabet(); method , class B has also alphabet(); method. Now class C extends A, B and we are creating object to the subclass i.e., class C , so  C ob = new C(); Then if you want call those methods ob.alphabet(); which class method takes ? is class A method or class B method ?  So in the JVM level ambiguity problem occurred. Thus Java does not support multiple inheritance.

Make use of jquery toggle function which do the task for you

.toggle() - Display or hide the matched elements.

$('#myelement').click(function(){
      $('#another-element').toggle('slow');
  });

When you install Python, it will not overwrite other installs of other major versions. So installing Python 2.5.x will not overwrite Python 2.6.x, although installing 2.6.6 will overwrite 2.6.5.

So you can just install it. Then you call the Python version you want. For example:

C:\Python2.5\Python.exe

for Python 2.5 on windows and

C:\Python2.6\Python.exe

for Python 2.6 on windows, or

/usr/local/bin/python-2.5

or

/usr/local/bin/python-2.6

on Windows Unix (including Linux and OS X).

When you install on Unix (including Linux and OS X) you will get a generic python command installed, which will be the last one you installed. This is mostly not a problem as most scripts will explicitly call /usr/local/bin/python2.5 or something just to protect against that. But if you don't want to do that, and you probably don't you can install it like this:

./configure
make
sudo make altinstall

Note the "altinstall" that means it will install it, but it will not replace the python command.

On Windows you don't get a global python command as far as I know so that's not an issue.

The above answer is not according to what Google Doc Referred for Location Tracking in Google api v2.

I just followed the official tutorial and ended up with this class that is fetching the current location and centring the map on it as soon as i get that.

you can extend this class to have LocationReciever to have periodic Location Update. I just executed this code on api level 7

Your file needs to be located inside your www directory. For example, if you're using wamp server on Windows, j3evn.jpg should be located,

C:/wamp/www/img/j3evn.jpg

and you can access it in html via

<img class="sealImage" alt="Image of Seal" src="../img/j3evn.jpg">

Look for the www, public_html, or html folder belonging to your web server. Place all your files and resources inside that folder.

Hope this helps!

@Draemon answers seems to be right with "-0" even with space in the file.

I was trying the xargs command and I found that "-0" works perfectly with "-L". even the spaces are treated (if input was null terminated ). the following is an example :

#touch "file with space"
#touch "file1"
#touch "file2"

The following will split the nulls and execute the command on each argument in the list :

 #find . -name 'file*' -print0 | xargs -0 -L1
./file with space
./file1
./file2

so -L1 will execute the argument on each null terminated character if used with "-0". To see the difference try :

 #find . -name 'file*' -print0 | xargs -0 | xargs -L1
 ./file with space ./file1 ./file2

even this will execute once :

 #find . -name 'file*' -print0  | xargs -0  | xargs -0 -L1
./file with space ./file1 ./file2

The command will execute once as the "-L" now doesn't split on null byte. you need to provide both "-0" and "-L" to work.

You can find stats-dot-com - personally I think their are better than opta. ESPN seems don't provide data in full and do not provide live data feeds (unfortunatelly).

We've been seeking for official data feed providing for our fantasy games (solutionsforfantasysport.com) and still staying with stats-com mainly (used opta, datafactory as well)

You can use both jquery and javascript method: if you have two images for example:

<img class="image1" src="image1.jpg" alt="image">
<img class="image2" src="image2.jpg" alt="image">

1)Jquery Method->

$(".image2").attr("src","image1.jpg");

2)Javascript Method->

var image = document.getElementsByClassName("image2");
image.src = "image1.jpg"

For this type of issue jquery is the simple one to use.

The pedantic answer (though not necessarily the most useful one, depending on what you want to do with the result) is:

string.length() * 2

Java strings are physically stored in UTF-16BE encoding, which uses 2 bytes per code unit, and String.length() measures the length in UTF-16 code units, so this is equivalent to:

final byte[] utf16Bytes= string.getBytes("UTF-16BE");
System.out.println(utf16Bytes.length);

And this will tell you the size of the internal char array, in bytes.

Note: "UTF-16" will give a different result from "UTF-16BE" as the former encoding will insert a BOM, adding 2 bytes to the length of the array.

In a word - speed. An index for up to a million rows fits in a 32-bit word, so it can be used efficiently on 32-bit processors. Function arguments that fit in a CPU register are extremely efficient, while ones that are larger require accessing memory on each function call, a far slower operation. Updating a spreadsheet can be an intensive operation involving many cell references, so speed is important. Besides, the Excel team expects that anyone dealing with more than a million rows will be using a database rather than a spreadsheet.

The cause if had for this problem was IIS Express not allowing WindowsAuthentication. This can be enabled by setting

<windowsAuthentication enabled="true">

in the applicationhost.config file located at C:\Users[username]\Documents\IISExpress\config.

For those who are searching custom border and shape of ImageView. You can use android-shape-imageview

Just add compile 'com.github.siyamed:android-shape-imageview:0.9.+@aar' to your build.gradle.

And use in your layout.

<com.github.siyamed.shapeimageview.BubbleImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/neo"
    app:siArrowPosition="right"
    app:siSquare="true"/>

I tried to do this in next way

public static DataTable JoinTwoTables(DataTable innerTable, DataTable outerTable)
        {
            DataTable resultTable = new DataTable();
            var innerTableColumns = new List<string>();
            foreach (DataColumn column in innerTable.Columns)
            {
                innerTableColumns.Add(column.ColumnName);
                resultTable.Columns.Add(column.ColumnName);
            }

            var outerTableColumns = new List<string>();
            foreach (DataColumn column in outerTable.Columns)
            {
                if (!innerTableColumns.Contains(column.ColumnName))
                {
                    outerTableColumns.Add(column.ColumnName);
                    resultTable.Columns.Add(column.ColumnName);
                }                    
            }

            for (int i = 0; i < innerTable.Rows.Count; i++)
            {
                var row = resultTable.NewRow();
                innerTableColumns.ForEach(x =>
                {
                    row[x] = innerTable.Rows[i][x];
                });
                outerTableColumns.ForEach(x => 
                {
                    row[x] = outerTable.Rows[i][x];
                });
                resultTable.Rows.Add(row);
            }
            return resultTable;
        }

This is an old question, but since it still comes up at the top of my results in Google, here's another way.

import pandas as pd
import numpy as np

df = pd.DataFrame({'col1':list("abc"),'col2':range(3)},index = range(3))

Say you want to replicate the rows where col1="b".

reps = [3 if val=="b" else 1 for val in df.col1]
df.loc[np.repeat(df.index.values, reps)]

You could replace the 3 if val=="b" else 1 in the list interpretation with another function that could return 3 if val=="b" or 4 if val=="c" and so on, so it's pretty flexible.

I was encountering this error while compiling my application with SDL. This was caused by SDL defining it's own main function in SDL_main.h. To prevent SDL define the main function an SDL_MAIN_HANDLED macro has to be defined before the SDL.h header is included.

Further to Cody Gray's answer, there's a third way (everything there applies her as well):

You can also use a dynamic array that's resized on the fly:

Dim test() as String
Dim arraySize as Integer

Do While someCondition
    '...whatever
    arraySize = arraySize + 1
    ReDim Preserve test(arraySize)
    test(arraySize) = newStringValue
Loop

Note the Preserve keyword. Without it, redimensioning an array also initializes all the elements.

On Cygwin -mcmodel=medium is already default and doesn't help. To me adding -Wl,--image-base -Wl,0x10000000 to GCC linker did fixed the error.

You can achieve it by code also, In you Global.asax file in Session_Start event write response.redirect to your start page like following.

void Session_Start(object sender, EventArgs e)
        {
            // Code that runs when a new session is started

            Response.Redirect("~/Index.aspx");

        }

You can get redirect page name from database or any other storage to change the application start page while application is running no need to edit web.config or change any IIS settings

Practically speaking, the :undolist is hard to use and Vim’s :earlier and :later time tracking of changes is only usable for course-grain fixes.

Given that, I resort to a plug-in that combines these features to provide a visual tree of browsable undos, called “Gundo.”

Obviously, this is something to use only when you need a fine-grained fix, or you are uncertain of the exact state of the document you wish to return to. See: Gundo. Graph your Vim undo tree in style

I've found the following method to be the most reliable when dealing with edge cases that trip up offsetTop/offsetLeft.

function getPosition(element) {
    var clientRect = element.getBoundingClientRect();
    return {left: clientRect.left + document.body.scrollLeft,
            top: clientRect.top + document.body.scrollTop};
}

List is interface and ArrayList is implemented concrete class. It is always recommended to use.

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

Because here list reference is flexible. It can also hold LinkedList or Vector object.

The main problem as stated by preceding coments is malformed HTML, so an html cleaner or HTML-XML converter is a must. Once you get the XML code (XHTML) there are plenty of tools to handle it. You could get it with a simple SAX handler that extracts only the data you need or any tree-based method (DOM, JDOM, etc.) that let you even modify original code.

Here is a sample code that uses HTML cleaner to get all DIVs that use a certain class and print out all Text content inside it.

I was running into the problem of the tooltip doing some funky stuff when the close button became clicked. To work around this I used a span instead of using a button. Also, when the close button was clicked I would have to click the tooltip twice after it closed in order to get it to open again. To work around this I simply used the .click() method, as seen below.

<span tabindex='0' class='tooltip-close close'>×</span>

$('#myTooltip').tooltip({
    html: true,
    title: "Hello From Tooltip",
    trigger: 'click'
});    

$("body").on("click", ".tooltip-close", function (e) {
    else {
        $('.tooltip').remove();
        $('#postal-premium-tooltip').click();
    }
});

Your default alignment is probably 4 bytes. Either the 30 byte element got 32, or the structure as a whole was rounded up to the next 4 byte interval.

just call this method where you need dynamic Height for label

func getHeightforController(view: AnyObject) -> CGFloat {
    let tempView: UILabel = view as! UILabel
    var context: NSStringDrawingContext = NSStringDrawingContext()
    context.minimumScaleFactor = 0.8

    var width: CGFloat = tempView.frame.size.width

    width = ((UIScreen.mainScreen().bounds.width)/320)*width

    let size: CGSize = tempView.text!.boundingRectWithSize(CGSizeMake(width, 2000), options:NSStringDrawingOptions.UsesLineFragmentOrigin, attributes: [NSFontAttributeName: tempView.font], context: context).size as CGSize

    return size.height
}

If you have cygwin installed, from it's bash shell, run your executable, say MyProgram, using the time utility, like so:

/usr/bin/time ./MyProgram

This will report how long the execution of your program took -- the output would look something like the following:

real    0m0.792s
user    0m0.046s
sys     0m0.218s

You could also manually modify your C program to instrument it using the clock() library function, like so:

#include <time.h>
int main(void) {
    clock_t tStart = clock();
    /* Do your stuff here */
    printf("Time taken: %.2fs\n", (double)(clock() - tStart)/CLOCKS_PER_SEC);
    return 0;
}

Something simpler than what @Milen proposed but it gives YYYY-MM-DD instead of the DD-MM-YYYY you wanted :

SUBSTRING((DT_STR,30, 1252) GETDATE(), 1, 10)

As an alternative answer, there's a command line to invoke directly the Control Panel, which is javaws -viewer, should work for both openJDK and Oracle's JDK (thanks @Nasser for checking the availability in Oracle's JDK)

Same caution to run as the user you need to access permissions with applies.

Also can be done from the environment variable:

export CURL_CA_BUNDLE=""

The string representation of a DateTime can be parsed by the Time class.

> Time.parse(DateTime.now.to_s).utc
=> 2015-10-06 14:53:51 UTC

This answer was not working for me so I went on to MSDN. There I found that now the code should look like this:

//var is of MessageBoxResult type
var result = MessageBox.Show(message, caption,
                             MessageBoxButtons.YesNo,
                             MessageBoxIcon.Question);

// If the no button was pressed ... 
if (result == DialogResult.No)
{
    ...
}

Hope it helps

you can also add the data-container="body" which should do the job :

<div class="row">
    <div class="col-md-6">
        <label for="name">Name:</label>
        <input id="name" class="form-control" type="text" 
                         data-toggle="popover" data-trigger="hover"

                         data-container="body"

                         data-content="My popover content.My popover content.My popover content.My popover content." />
    </div>
</div>

Yup, a UIAlertView is probably what you're looking for. Here's an example:

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"No network connection" 
                                                message:@"You must be connected to the internet to use this app." 
                                               delegate:nil 
                                      cancelButtonTitle:@"OK"
                                      otherButtonTitles:nil];
[alert show];
[alert release];

If you want to do something more fancy, say display a custom UI in your UIAlertView, you can subclass UIAlertView and put in custom UI components in the init method. If you want to respond to a button press after a UIAlertView appears, you can set the delegate above and implement the - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex method.

You might also want to look at the UIActionSheet.

Method 1: Use a hash

Logic: A hash can have only unique keys, so iterate over array, assign any value to each element of array, keeping element as key of that hash. Return keys of the hash, its your unique array.

my @unique = keys {map {$_ => 1} @array};

Method 2: Extension of method 1 for reusability

Better to make a subroutine if we are supposed to use this functionality multiple times in our code.

sub get_unique {
    my %seen;
    grep !$seen{$_}++, @_;
}
my @unique = get_unique(@array);

Method 3: Use module List::MoreUtils

use List::MoreUtils qw(uniq);
my @unique = uniq(@array);

Differentiate between the two cases you named:

• To indicate that the requested operation is not supported and most likely never will, throw an UnsupportedOperationException.

• To indicate the requested operation has not been implemented yet, choose between this:

  1. Use the NotImplementedException from apache commons-lang which was available in commons-lang2 and has been re-added to commons-lang3 in version 3.2.

  2. Implement your own NotImplementedException.

  3. Throw an UnsupportedOperationException with a message like "Not implemented, yet".

You can use Character#toUpperCase() for this.

char fUpper = Character.toUpperCase(f);
char lUpper = Character.toUpperCase(l);

It has however some limitations since the world is aware of many more characters than can ever fit in 16bit char range. See also the following excerpt of the javadoc:

Note: This method cannot handle supplementary characters. To support all Unicode characters, including supplementary characters, use the toUpperCase(int) method.

PATTERN FORMAT

• A blank line matches no files, so it can serve as a separator for readability.

• A line starting with # serves as a comment.

• An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again. If a negated pattern matches, this will override lower precedence patterns sources.

• If the pattern ends with a slash, it is removed for the purpose of the following description, but it would only find a match with a directory. In other words, foo/ will match a directory foo and paths underneath it, but will not match a regular file or a symbolic link foo (this is consistent with the way how pathspec works in general in git).

• If the pattern does not contain a slash /, git treats it as a shell glob pattern and checks for a match against the pathname relative to the location of the .gitignore file (relative to the toplevel of the work tree if not from a .gitignore file).

• Otherwise, git treats the pattern as a shell glob suitable for consumption by fnmatch(3) with the FNM_PATHNAME flag: wildcards in the pattern will not match a / in the pathname. For example, Documentation/*.html matches Documentation/git.html but not Documentation/ppc/ppc.html or tools/perf/Documentation/perf.html.

• A leading slash matches the beginning of the pathname. For example, /*.c matches cat-file.c but not mozilla-sha1/sha1.c.

man gitignore

There are two possible scenario,

1. If you application run on .net framework 4.5 or less than that and you can easily deploy new code to the production then you can use of below solution.

   You can add below line of code before making api call,

   ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12; // .NET 4.5

2. If you cannot deploy new code and you want to resolve with the same code which is present in the production, then you have two options.

Option 1 :

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

then create a file with extension .reg and install.

Note : This setting will apply at registry level and is applicable to all application present on that machine and if you want to restrict to only single application then you can use Option 2

Option 2 : This can be done by changing some configuration setting in config file. You can add either of one in your config file.

<runtime>
    <AppContextSwitchOverrides value="Switch.System.Net.DontEnableSchUseStrongCrypto=false"/>
  </runtime>

or

<runtime>
  <AppContextSwitchOverrides value="Switch.System.Net.DontEnableSystemDefaultTlsVersions=false"
</runtime>

If you look at the documentation you can take just the properties you're interested in from the window object i.e.

protocol + '//' + hostname + pathname

You asked of Function but there is an easier way too. When you will upload the image, copy it's URL which is at the top right part of the window (View Screenshot) and paste it in the src='[link you copied]'. Hope this will help if someone is looking for similar problem.

Some date utilities, including comparisons IN ENGLISH, which is nice:

#import <Foundation/Foundation.h>


@interface NSDate (Util)

-(BOOL) isLaterThanOrEqualTo:(NSDate*)date;
-(BOOL) isEarlierThanOrEqualTo:(NSDate*)date;
-(BOOL) isLaterThan:(NSDate*)date;
-(BOOL) isEarlierThan:(NSDate*)date;
- (NSDate*) dateByAddingDays:(int)days;

@end

The implementation:

#import "NSDate+Util.h"


@implementation NSDate (Util)

-(BOOL) isLaterThanOrEqualTo:(NSDate*)date {
    return !([self compare:date] == NSOrderedAscending);
}

-(BOOL) isEarlierThanOrEqualTo:(NSDate*)date {
    return !([self compare:date] == NSOrderedDescending);
}
-(BOOL) isLaterThan:(NSDate*)date {
    return ([self compare:date] == NSOrderedDescending);

}
-(BOOL) isEarlierThan:(NSDate*)date {
    return ([self compare:date] == NSOrderedAscending);
}

- (NSDate *) dateByAddingDays:(int)days {
    NSDate *retVal;
    NSDateComponents *components = [[NSDateComponents alloc] init];
    [components setDay:days];

    NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
    retVal = [gregorian dateByAddingComponents:components toDate:self options:0];
    return retVal;
}

@end

Instead of parsing it manually it's better to use pathinfo function:

$path_parts = pathinfo($value);
$extension = strtolower($path_parts['extension']);
$fileName = $path_parts['filename'];

Try this:

subset(studentdata, Drink=='water')

that should do it.

use spawn

import os
os.spawnlp(os.P_WAIT, 'cp', 'cp', 'index.html', '/dev/null')

<?php
  $field = 'display_name';
  the_author_meta($field);
?>

Valid values for the $field parameter include:

• admin_color
• aim
• comment_shortcuts
• description
• display_name
• first_name
• ID
• jabber
• last_name
• nickname
• plugins_last_view
• plugins_per_page
• rich_editing
• syntax_highlighting
• user_activation_key
• user_description
• user_email
• user_firstname
• user_lastname
• user_level
• user_login
• user_nicename
• user_pass
• user_registered
• user_status
• user_url
• yim

I have some additions to above mentioned answers Its infact a hack mentioned by Jesse Wilson from okhttp, square here. According to this hack, i had to rename my SSLSocketFactory variable to

private SSLSocketFactory delegate;

This is my TLSSocketFactory class

public class TLSSocketFactory extends SSLSocketFactory {

private SSLSocketFactory delegate;

public TLSSocketFactory() throws KeyManagementException, NoSuchAlgorithmException {
    SSLContext context = SSLContext.getInstance("TLS");
    context.init(null, null, null);
    delegate = context.getSocketFactory();
}

@Override
public String[] getDefaultCipherSuites() {
    return delegate.getDefaultCipherSuites();
}

@Override
public String[] getSupportedCipherSuites() {
    return delegate.getSupportedCipherSuites();
}

@Override
public Socket createSocket() throws IOException {
    return enableTLSOnSocket(delegate.createSocket());
}

@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
    return enableTLSOnSocket(delegate.createSocket(s, host, port, autoClose));
}

@Override
public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
    return enableTLSOnSocket(delegate.createSocket(host, port));
}

@Override
public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
    return enableTLSOnSocket(delegate.createSocket(host, port, localHost, localPort));
}

@Override
public Socket createSocket(InetAddress host, int port) throws IOException {
    return enableTLSOnSocket(delegate.createSocket(host, port));
}

@Override
public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
    return enableTLSOnSocket(delegate.createSocket(address, port, localAddress, localPort));
}

private Socket enableTLSOnSocket(Socket socket) {
    if(socket != null && (socket instanceof SSLSocket)) {
        ((SSLSocket)socket).setEnabledProtocols(new String[] {"TLSv1.1", "TLSv1.2"});
    }
    return socket;
}
}

and this is how i used it with okhttp and retrofit

 OkHttpClient client=new OkHttpClient();
    try {
        client = new OkHttpClient.Builder()
                .sslSocketFactory(new TLSSocketFactory())
                .build();
    } catch (KeyManagementException e) {
        e.printStackTrace();
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(URL)
            .client(client)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

Implemented this way without using Jquery:

<button class="emailReplyButton" onClick="sendEmail(message)">Reply</button>

sendEmail(message) {
    var email = message.emailId;
    var subject = message.subject;
    var emailBody = 'Hi '+message.from;
    document.location = "mailto:"+email+"?subject="+subject+"&body="+emailBody;
}

Qt provides the simplest API

const char *qPrintable(const QString &str)
const char *qUtf8Printable(const QString &str)

If you want non-const data pointer use

str.toLocal8Bit().data()
str.toUtf8().data()

Although the identity of two queries seems obvious sometimes some strange things happens. I have come accros the query wich has different execution plans when moving join predicate from JOIN to WHERE in Oracle 10g (for WHERE plan is better), but I can't reproduce this issue in simplified tables and data. I think it depends on my data and statistics. Optimizer is quite complex module and sometimes it behaves magically.

Thats why we can't answer to this question in general because it depends on DB internals. But we should know that answer has to be 'no differences'.

Your Money class could be represented as a subclass of Long or having a member representing the money value as a native long. Then when assigning values to your money instantiations, you will always be storing values that are actually REAL money values. You simply output your Money object (via your Money's overridden toString() method) with the appropriate formatting. e.g $1.25 in a Money object's internal representation is 125. You represent the money as cents, or pence or whatever the minimum denomination in the currency you are sealing with is ... then format it on output. No you can NEVER store an 'illegal' money value, like say $1.257.

$_SERVER['REQUEST_TIME']

check out that too. i.e.

...
// your codes running
...
echo (time() - $_SERVER['REQUEST_TIME']);

try this with jQuery:

$('body').load( url,[data],[callback] );

For some browsers you can use

object-fit: cover;

http://caniuse.com/object-fit

Instead of using cat and I/O redirection it might be useful to use tee instead:

tee newfile <<EOF
line 1
line 2
line 3
EOF

It's more concise, plus unlike the redirect operator it can be combined with sudo if you need to write to files with root permissions.

This may help you.

<RelativeLayout
    android:id="@+id/textbox"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:background="@android:color/darker_gray" >

    <TextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:layout_margin="3dp"
        android:background="@android:color/white"
        android:gravity="center"
        android:text="@string/app_name"
        android:textSize="20dp" />

Also see the speeded-up package ujson:

import ujson

with open('data.json', 'wb') as fp:
    ujson.dump(data, fp)

First, always sudo nginx -t to verify your config files are good.

I ran into the same problem. The reason I had the issue was twofold. First, I had accidentally copied a log file into my site-enabled folder. I deleted the log file and made sure that all the files in sites-enabled were proper nginx site configs. I also noticed two of my virtual hosts were listening for the same domain. So I made sure that each of my virtual hosts had unique domain names.

sudo service nginx restart

Then it worked.

I encountered a similar problem when I was trying to connect my Django application to PostgreSQL database.

I wrote my Dockerfile with instructions to setup the Django project followed by instructions to install PostgreSQL and run Django server in my docker-compose.yml.

I defined two services in my docker-compose-yml.

services:
  postgres:
    image: "postgres:latest"
    environment:
      - POSTGRES_DB=abc
      - POSTGRES_USER=abc
      - POSTGRES_PASSWORD=abc
    volumes:
      - pg_data:/var/lib/postgresql/data/
  django:
    build: .
    command: python /code/manage.py runserver 0.0.0.0:8004
    volumes:
      - .:/app
    ports:
      - 8004:8004
    depends_on:
      - postgres 

Unfortunately whenever I used to run docker-compose up then same err. used to pop up.

And this is how my database was defined in Django settings.py.

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'abc',
        'USER': 'abc',
        'PASSWORD': 'abc',
        'HOST': '127.0.0.1',
        'PORT': '5432',
        'OPTIONS': {
            'client_encoding': 'UTF8',
        },
    }
} 

So, In the end I made use of docker-compose networking which means if I change the host of my database to postgres which is defined as a service in docker-compose.yml will do the wonders.

So, Replacing 'HOST': '127.0.0.1' => 'HOST': 'postgres' did wonders for me.

After replacement this is how your Database config in settings.py will look like.

DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.postgresql',
            'NAME': 'abc',
            'USER': 'abc',
            'PASSWORD': 'abc',
            'HOST': 'postgres',
            'PORT': '5432',
            'OPTIONS': {
                'client_encoding': 'UTF8',
            },
        }
    } 

You are making sense, but you seem to misunderstand the concept of sending emails.

HTML is parsed on the client side, while the e-mail needs to be sent from the server. You cannot do it in pure HTML. I would suggest writing a PHP script that will deal with the email sending for you.

Basically, instead of the MAILTO, your form's action will need to point to that PHP script. In the script, retrieve the values passed by the form (in PHP, they are available through the $_POST superglobal) and use the email sending function (mail()).

Of course, this can be done in other server-side languages as well. I'm giving a PHP solution because PHP is the language I work with.

A simple example code:

form.html:

<form method="post" action="email.php">
    <input type="text" name="subject" /><br />
    <textarea name="message"></textarea>
</form>

email.php:

<?php
    mail('[email protected]', $_POST['subject'], $_POST['message']);
?>
<p>Your email has been sent.</p>

Of course, the script should contain some safety measures, such as checking whether the $_POST valies are at all available, as well as additional email headers (sender's email, for instance), perhaps a way to deal with character encoding - but that's too complex for a quick example ;).

None of this will work as expected.. The correct way is to change position: fixed to position: absolute for .modal class

This question has been asked before. Please see this question.

Using the accepted answer and adapting it to your problem you get:

SELECT tt.*
FROM myTable tt
INNER JOIN
    (SELECT ID, MAX(Date) AS MaxDateTime
    FROM myTable
    GROUP BY ID) groupedtt 
ON tt.ID = groupedtt.ID 
AND tt.Date = groupedtt.MaxDateTime

class B
{
public:
    B()
    {
       p = new int[1024];  
    }
    virtual ~B()
    {
        cout<<"B destructor"<<endl;
        //p will not be deleted EVER unless you do it manually.
    }
    int *p;
};


class D : public B
{
public:
    virtual ~D()
    {
        cout<<"D destructor"<<endl;
    }
};

When you do:

B *pD = new D();
delete pD;

The destructor will be called only if your base class has the virtual keyword.

Then if you did not have a virtual destructor only ~B() would be called. But since you have a virtual destructor, first ~D() will be called, then ~B().

No members of B or D allocated on the heap will be deallocated unless you explicitly delete them. And deleting them will call their destructor as well.

I followed this tutorial, and everything is OK.

You can resize using style and width to resize the textbox. Here is the code for it.

<!DOCTYPE html>_x000D_
<html lang="en">_x000D_
<head>_x000D_
    <meta charset="UTF-8">_x000D_
_x000D_
</head>_x000D_
<body>_x000D_
<div align="center">_x000D_
_x000D_
    <form method="post">_x000D_
          <div class="w3-row w3-section">_x000D_
            <div class="w3-rest" align = "center">_x000D_
                <input name="lastName" type="text" id="myInput" style="width: 50%">_x000D_
            </div>_x000D_
        </div>_x000D_
    </form>_x000D_
</div>_x000D_
</body>_x000D_
</html>

Use align to center the textbox.

Building on Chad's answer, you also want to add that function to the onload event to ensure it is resized when the page loads as well.

jQuery.event.add(window, "load", resizeFrame);
jQuery.event.add(window, "resize", resizeFrame);

function resizeFrame() 
{
    var h = $(window).height();
    var w = $(window).width();
    $("#elementToResize").css('height',(h < 768 || w < 1024) ? 500 : 400);
}

Visual Studio 2015 doesn't install C++ by default. You have to rerun the setup, select Modify and then check Programming Language -> C++

Learn Java String Intern - once for all

Strings in java are immutable objects by design. Therefore, two string objects even with same value will be different objects by default. However, if we wish to save memory, we could indicate to use same memory by a concept called string intern.

The below rules would help you understand the concept in clear terms:

1. String class maintains an intern-pool which is initially empty. This pool must guarantee to contain string objects with only unique values.
2. All string literals having same value must be considered same memory-location object because they have otherwise no notion of distinction. Therefore, all such literals with same value will make a single entry in the intern-pool and will refer to same memory location.
3. Concatenation of two or more literals is also a literal. (Therefore rule #2 will be applicable for them)
4. Each string created as object (i.e. by any other method except as literal) will have different memory locations and will not make any entry in the intern-pool
5. Concatenation of literals with non-literals will make a non-literal. Thus, the resultant object will have a new memory location and will NOT make an entry in the intern-pool.
6. Invoking intern method on a string object, either creates a new object that enters the intern-pool or return an existing object from the pool that has same value. The invocation on any object which is not in the intern-pool, does NOT move the object to the pool. It rather creates another object that enters the pool.

Example:

String s1=new String (“abc”);
String s2=new String (“abc”);
If (s1==s2)  //would return false  by rule #4
If (“abc” == “a”+”bc” )  //would return true by rules #2 and #3
If (“abc” == s1 )  //would return false  by rules #1,2 and #4
If (“abc” == s1.intern() )  //would return true  by rules #1,2,4 and #6
If ( s1 == s2.intern() )      //wound return false by rules #1,4, and #6

Note: The motivational cases for string intern are not discussed here. However, saving of memory will definitely be one of the primary objectives.

Use __time function:

• ${__time(dd/MM/yyyy,)}

• ${__time(hh:mm a,)}

Since JMeter 3.3, there are two new functions that let you compute a time:

__timeShift

  "The timeShift function returns a date in the given format with the specified amount of seconds, minutes, hours, days or months added" and 

__RandomDate

  "The RandomDate function returns a random date that lies between the given start date and end date values." 

Since JMeter 4.0:

dateTimeConvert

Convert a date or time from source to target format

If you're looking to learn jmeter correctly, this book will help you.

You should create custom helper for just changing string format except using controller call.

jquery is your friend here.

http://docs.jquery.com/UI/Tree

If you want to make your own, here is some high level guidance:

Display all of your data as <ul /> elements with the inner data as nested <ul />, and then use the jquery:

$('.ulClass').click(function(){ $(this).children().toggle(); });

I believe that is correct. Something like that.

EDIT:

Here is a complete example.

Here are the steps for send email from localhost by wamp server with Sendmail.

1. First, you need to download Sendmail zip file link
2. Extract the zip file and put it on C:\wamp
3. Now, you need to edit Sendmail.ini on C:\wamp\sendmail\sendmail.ini

smtp_server=smtp.gmail.com 
smtp_port=465
[email protected]
auth_password=your_password

4. Access your email account. Click the Gear Tool > Settings > Forwarding and POP/IMAP > IMAP access. Click "Enable IMAP", then save your changes
5. Run your WAMP Server. Enable ssl_module under Apache Module.
6. Next, enable php_openssl and php_sockets under PHP.
7. ** Now the important part open php.ini file on "C:\wamp\bin\php\php5.5.12\php.ini" and "C:\wamp\bin\apache\apache2.4.9\bin\php.ini" set sendmail_path **

sendmail_path = "C:\wamp\sendmail\sendmail.exe -t"

8. Restart Wamp Server.

It will surely be worked.

I had the same requirements as you but couldn't find a suitable database. nStore was promising but the API was not nearly complete enough and not very coherent.

That's why I made NeDB, which a dependency-less embedded database for Node.js projects. You can use it with a simple require(), it is persistent, and its API is the most commonly used subset of the very well-known MongoDB API.

If you are using a newer version (over 1.3.x) you should learn more about the function parseJSON! I experienced the same problem. Use an old version or change your code

success=function(data){
  //something like this
  jQuery.parseJSON(data)
}

Bash has built in features to access the last command executed. But that's the last whole command (e.g. the whole case command), not individual simple commands like you originally requested.

!:0 = the name of command executed.

!:1 = the first parameter of the previous command

!:* = all of the parameters of the previous command

!:-1 = the final parameter of the previous command

!! = the previous command line

etc.

So, the simplest answer to the question is, in fact:

echo !!

...alternatively:

echo "Last command run was ["!:0"] with arguments ["!:*"]"

Try it yourself!

echo this is a test
echo !!

In a script, history expansion is turned off by default, you need to enable it with

set -o history -o histexpand

Use Dictionary Items:

{% for key, value in my_dictionay.items %}
  <li>{{ key }} : {{ value }}</li>
{% endfor %}

I use the following code:

<Button onClick={this.onSubmit} id={item.key} value={shop.ethereum}>
    Approve
</Button>

Then inside the method:

onSubmit = async event => {
    event.preventDefault();
    event.persist();
    console.log("Param passed => Eth addrs: ", event.target.value)
    console.log("Param passed => id: ", event.target.id)
    ...
}

As a result:

Param passed in event => Eth addrs: 0x4D86c35fdC080Ce449E89C6BC058E6cc4a4D49A6

Param passed in event => id: Mlz4OTBSwcgPLBzVZ7BQbwVjGip1

Sam's solution is already great, despite it doesn't take different bundles into account (NSBundle:forClass comes to the rescue) and requires manual loading, a.k.a typing code.

If you want full support for your Xib Outlets, different Bundles (use in frameworks!) and get a nice preview in Storyboard try this:

// NibLoadingView.swift
import UIKit

/* Usage: 
- Subclass your UIView from NibLoadView to automatically load an Xib with the same name as your class
- Set the class name to File's Owner in the Xib file
*/

@IBDesignable
class NibLoadingView: UIView {

    @IBOutlet weak var view: UIView!

    override init(frame: CGRect) {
        super.init(frame: frame)
        nibSetup()
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        nibSetup()
    }

    private func nibSetup() {
        backgroundColor = .clearColor()

        view = loadViewFromNib()
        view.frame = bounds
        view.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]
        view.translatesAutoresizingMaskIntoConstraints = true

        addSubview(view)
    }

    private func loadViewFromNib() -> UIView {
        let bundle = NSBundle(forClass: self.dynamicType)
        let nib = UINib(nibName: String(self.dynamicType), bundle: bundle)
        let nibView = nib.instantiateWithOwner(self, options: nil).first as! UIView

        return nibView
    }

}

Use your xib as usual, i.e. connect Outlets to File Owner and set File Owner class to your own class.

Usage: Just subclass your own View class from NibLoadingView & Set the class name to File's Owner in the Xib file

No additional code required anymore.

Credits where credit's due: Forked this with minor changes from DenHeadless on GH. My Gist: https://gist.github.com/winkelsdorf/16c481f274134718946328b6e2c9a4d8

What I can think of is to stretch either width or height and let it resize in ratio-aspect. There will be some white space on the sides. Something like how a Wide screen displays a resolution of 1024x768.

You can call get() with the path to Chrome. Below is an example - replace chrome_path with the correct path for your platform.

import webbrowser

url = 'http://docs.python.org/'

# MacOS
chrome_path = 'open -a /Applications/Google\ Chrome.app %s'

# Windows
# chrome_path = 'C:/Program Files (x86)/Google/Chrome/Application/chrome.exe %s'

# Linux
# chrome_path = '/usr/bin/google-chrome %s'

webbrowser.get(chrome_path).open(url)

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

Example query:

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

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

As @NickT said, there's no python3[4-6] in the default yum repos in Amazon Linux 2, as of today it uses 3.7 and looking at all answers here we can say it will be changed over time.

I was looking for python3.6 on Amazon Linux 2 but amazon-linux-extras shows a lot of options but no python at all. in fact, you can try to find the version you know in epel repo:

sudo amazon-linux-extras install epel

yum search python | grep "^python3..x8"

python34.x86_64 : Version 3 of the Python programming language aka Python 3000
python36.x86_64 : Interpreter of the Python programming language

Route::group(['middleware' => 'web'], function () {
Route::auth();

Route::get('/', ['as' => 'home', 'uses' => 'BaseController@index']);

Route::group(['namespace' => 'User', 'prefix' => 'user'], function(){
    Route::get('{nickname}/settings', ['as' => 'user.settings', 'uses' => 'SettingsController@index']);
    Route::get('{nickname}/profile', ['as' => 'user.profile', 'uses' => 'ProfileController@index']);
});
});

If you want to append text or html to span then you can do it as below.

$('p span#add_here').append('text goes here');

append will add text to span tag at the end.

to replace entire text or html inside of span you can use .text() or .html()

This error can be caused by an unclosed set of brackets.

int main {
  doSomething {}
  doSomething else {
}

Not so easy to spot, even in this 4 line example.

This error, in a 150 line main function, caused the bewildering error: "static declaration of ‘savePair’ follows non-static declaration". There was nothing wrong with my definition of function savePair, it was that unclosed bracket.

This is not about the difference between Window.ContentRendered and Window.Loaded but about what how the Window.Loaded event can be used:

I use it to avoid splash screens in all applications which need a long time to come up.

    // initializing my main window
    public MyAppMainWindow()
    {
        InitializeComponent();

        // Set the event
        this.ContentRendered += MyAppMainWindow_ContentRendered;
    }

    private void MyAppMainWindow_ContentRendered(object sender, EventArgs e)
    {
        // ... comes up quick when the controls are loaded and rendered

        // unset the event
        this.ContentRendered -= MyAppMainWindow_ContentRendered;

        // ... make the time comsuming init stuff here
    }

declare @p_Id varchar(10)
SET @p_Id = '40381'

EXECUTE ('BEGIN update TableName
                set     ColumnName1 = null,
                        ColumnName2 = null,
                        ColumnName3 = null,
                        ColumnName4 = null
                 where   PERSONID = '+ @p_Id +'; END;') AT [linked_Server_Name]

How to get the current key of an array when using array_filter

Regardless of how I like Vincent's solution for Macek's problem, it doesn't actually use array_filter. If you came here from a search engine you maybe where looking for something like this (PHP >= 5.3):

$array = ['apple' => 'red', 'pear' => 'green'];
reset($array); // Unimportant here, but make sure your array is reset

$apples = array_filter($array, function($color) use ($&array) {
  $key = key($array);
  next($array); // advance array pointer

  return key($array) === 'apple';
}

It passes the array you're filtering as a reference to the callback. As array_filter doesn't conventionally iterate over the array by increasing it's public internal pointer you have to advance it by yourself.

What's important here is that you need to make sure your array is reset, otherwise you might start right in the middle of it.

In PHP >= 5.4 you could make the callback even shorter:

$apples = array_filter($array, function($color) use ($&array) {
  return each($array)['key'] === 'apple';
}

They are not the same. The first one replaces the HTML without creating another jQuery object first. The second creates an additional jQuery wrapper for the second div, then appends it to the first.

One jQuery Wrapper (per example):

$("#myDiv").html('<div id="mySecondDiv"></div>');

$("#myDiv").append('<div id="mySecondDiv"></div>');

Two jQuery Wrappers (per example):

var mySecondDiv=$('<div id="mySecondDiv"></div>');
$('#myDiv').html(mySecondDiv);

var mySecondDiv=$('<div id="mySecondDiv"></div>');
$('#myDiv').append(mySecondDiv);

You have a few different use cases going on. If you want to replace the content, .html is a great call since its the equivalent of innerHTML = "...". However, if you just want to append content, the extra $() wrapper set is unneeded.

Only use two wrappers if you need to manipulate the added div later on. Even in that case, you still might only need to use one:

var mySecondDiv = $("<div id='mySecondDiv'></div>").appendTo("#myDiv");
// other code here
mySecondDiv.hide();

For anyone else who doesn't need to do it programmatic, here's a quick way:

(probably for paid users only)

1. Open the channel in web or the desktop app, and click the cog (top right).
2. Choose "Additional options..." to bring up the archival menu. notes
3. Select "Set the channel message retention policy".
4. Set "Retain all messages for a specific number of days".
5. All messages older than this time are deleted permanently!

I usually set this option to "1 day" to leave the channel with some context, then I go back into the above settings, and set it's retention policy back to "default" to go continue storing them from now-on.

Notes:
Luke points out: If the option is hidden: you have to go to global workspace Admin settings, Message Retention & Deletion, and check "Let workspace members override these settings"

This worked for me.

header = ['row1', 'row2', 'row3']
some_list = [1, 2, 3]
with open('test.csv', 'wt', newline ='') as file:
    writer = csv.writer(file, delimiter=',')
    writer.writerow(i for i in header)
    for j in some_list:
        writer.writerow(j)

I found it was impossible to assign a layout to the centralwidget until I had added at least one child beneath it. Then I could highlight the tiny icon with the red 'disabled' mark and then click on a layout in the Designer toolbar at top.

path = pd.read_csv(**'C:\Users\mravi\Desktop\filename'**)

The error is because of the path that is mentioned

Add 'r' before the path

path = pd.read_csv(**r'C:\Users\mravi\Desktop\filename'**)

This would work fine.
