Its fine to just do char **strings;, char **strings = NULL, or char **strings = {NULL}

but to initialize it you'd have to use malloc:

#include <stdlib.h>
#include <stdio.h>
#include <string.h>

int main(){
    // allocate space for 5 pointers to strings
    char **strings = (char**)malloc(5*sizeof(char*));
    int i = 0;
    //allocate space for each string
    // here allocate 50 bytes, which is more than enough for the strings
    for(i = 0; i < 5; i++){
        printf("%d\n", i);
        strings[i] = (char*)malloc(50*sizeof(char));
    }
    //assign them all something
    sprintf(strings[0], "bird goes tweet");
    sprintf(strings[1], "mouse goes squeak");
    sprintf(strings[2], "cow goes moo");
    sprintf(strings[3], "frog goes croak");
    sprintf(strings[4], "what does the fox say?");
    // Print it out
    for(i = 0; i < 5; i++){
        printf("Line #%d(length: %lu): %s\n", i, strlen(strings[i]),strings[i]);
    } 
    //Free each string
    for(i = 0; i < 5; i++){
        free(strings[i]);
    }
    //finally release the first string
    free(strings);
    return 0;
}

I solved the simmilar problem, when i tried to push to repo via gitlab ci/cd pipeline by the command "gem install rake && bundle install"

Here's my implementation in Swift 5 for vertical cell-based paging:

override func targetContentOffset(forProposedContentOffset proposedContentOffset: CGPoint, withScrollingVelocity velocity: CGPoint) -> CGPoint {

    guard let collectionView = self.collectionView else {
        let latestOffset = super.targetContentOffset(forProposedContentOffset: proposedContentOffset, withScrollingVelocity: velocity)
        return latestOffset
    }

    // Page height used for estimating and calculating paging.
    let pageHeight = self.itemSize.height + self.minimumLineSpacing

    // Make an estimation of the current page position.
    let approximatePage = collectionView.contentOffset.y/pageHeight

    // Determine the current page based on velocity.
    let currentPage = velocity.y == 0 ? round(approximatePage) : (velocity.y < 0.0 ? floor(approximatePage) : ceil(approximatePage))

    // Create custom flickVelocity.
    let flickVelocity = velocity.y * 0.3

    // Check how many pages the user flicked, if <= 1 then flickedPages should return 0.
    let flickedPages = (abs(round(flickVelocity)) <= 1) ? 0 : round(flickVelocity)

    let newVerticalOffset = ((currentPage + flickedPages) * pageHeight) - collectionView.contentInset.top

    return CGPoint(x: proposedContentOffset.x, y: newVerticalOffset)
}

Some notes:

• Doesn't glitch
• SET PAGING TO FALSE! (otherwise this won't work)
• Allows you to set your own flickvelocity easily.
• If something is still not working after trying this, check if your itemSize actually matches the size of the item as that's often a problem, especially when using collectionView(_:layout:sizeForItemAt:), use a custom variable with the itemSize instead.
• This works best when you set self.collectionView.decelerationRate = UIScrollView.DecelerationRate.fast.

Here's a horizontal version (haven't tested it thoroughly so please forgive any mistakes):

override func targetContentOffset(forProposedContentOffset proposedContentOffset: CGPoint, withScrollingVelocity velocity: CGPoint) -> CGPoint {

    guard let collectionView = self.collectionView else {
        let latestOffset = super.targetContentOffset(forProposedContentOffset: proposedContentOffset, withScrollingVelocity: velocity)
        return latestOffset
    }

    // Page width used for estimating and calculating paging.
    let pageWidth = self.itemSize.width + self.minimumInteritemSpacing

    // Make an estimation of the current page position.
    let approximatePage = collectionView.contentOffset.x/pageWidth

    // Determine the current page based on velocity.
    let currentPage = velocity.x == 0 ? round(approximatePage) : (velocity.x < 0.0 ? floor(approximatePage) : ceil(approximatePage))

    // Create custom flickVelocity.
    let flickVelocity = velocity.x * 0.3

    // Check how many pages the user flicked, if <= 1 then flickedPages should return 0.
    let flickedPages = (abs(round(flickVelocity)) <= 1) ? 0 : round(flickVelocity)

    // Calculate newHorizontalOffset.
    let newHorizontalOffset = ((currentPage + flickedPages) * pageWidth) - collectionView.contentInset.left

    return CGPoint(x: newHorizontalOffset, y: proposedContentOffset.y)
}

This code is based on the code I use in my personal project, you can check it out here by downloading it and running the Example target.

No you don't need to check if you're in the main thread. Here is how you can do this in Swift:

runThisInMainThread { () -> Void in
    runThisInMainThread { () -> Void in
        // No problem
    }
}

func runThisInMainThread(block: dispatch_block_t) {
    dispatch_async(dispatch_get_main_queue(), block)
}

Its included as a standard function in my repo, check it out: https://github.com/goktugyil/EZSwiftExtensions

The object name is not very important. what you should be focusing at is the variable that stores the lineedit object (le) and your pushbutton object(pb)

QObject(self.pb, SIGNAL("clicked()"), self.button_clicked)

def button_clicked(self):
  self.le.setText("shost")

I think this is what you want. I hope i got your question correctly :)

This code will help a lot

function isObject(data){
    var tb = document.createElement("table");

    if(data !=null) {
        var keyOfobj = Object.keys(data);
        var ValOfObj = Object.values(data);

        for (var i = 0; i < keyOfobj.length; i++) {
            var tr = document.createElement('tr');
            var td = document.createElement('td');
            var key = document.createTextNode(keyOfobj[i]);

            td.appendChild(key);
            tr.appendChild(td);
            tb.appendChild(tr);

            if(typeof(ValOfObj[i]) == "object") {

                if(ValOfObj[i] !=null) {
                    tr.setAttribute("style","font-weight: bold");   
                    isObject(ValOfObj[i]);
                } else {
                    var td = document.createElement('td');
                    var value = document.createTextNode(ValOfObj[i]);

                    td.appendChild(value);
                    tr.appendChild(td);
                    tb.appendChild(tr);
                }
            } else {
                var td = document.createElement('td');
                var value = document.createTextNode(ValOfObj[i]);

                td.appendChild(value);
                tr.appendChild(td);
                tb.appendChild(tr);
            }
        }
    }
}

Append the following parameter to the Youtube-URL:

144p: &vq=tiny
240p: &vq=small
360p: &vq=medium
480p: &vq=large
720p: &vq=hd720

For instance:

src="http://www.youtube.com/watch?v=oDOXeO9fAg4"

becomes:

src="http://www.youtube.com/watch?v=oDOXeO9fAg4&vq=large"

Using jQuery:

var str = '{"id":1,"name":"Test1"},{"id":2,"name":"Test2"}';
var jsonObj = $.parseJSON('[' + str + ']');

jsonObj is your JSON object.

If the label is in a table row you can do this to hide the row:

('.InputFile').parent().Hide()

You can refine your selector as you need and then get the table row that contains that element.

JQuery Selectors help: http://api.jquery.com/category/selectors/

EDIT This is the correct way to do it.

    ('.InputFile').parents('tr').hide()

This one didn't seem too bad.

In your function form is a DOM object, In order to use attr() you need to convert it to jQuery object.

function f(form, fname, lname) {
    action = $(form).attr("action");
    $.post(att, {fname : fname , lname :lname}).done(function (data) {
        alert(data);
    });
    return true;
}

With .serialize()

function f(form, fname, lname) {
    action = $(form).attr("action");
    $.post(att, $(form).serialize() ).done(function (data) {
        alert(data);
    });
    return true;
}

Additionally, You can use .serialize()

The debug module can be used to analyze variables. Be careful running the following command. In our setup it generates 444709 lines with 16MB:

ansible -m debug -a 'var=hostvars' localhost

I am not sure but it might be necessary to enable facts caching.

If you need just one host use the host name as a key for the hostvars hash:

ansible -m debug -a 'var=hostvars.localhost' localhost

This command will display also group and host variables.

You can use this, just think Job is the name of the model to which you are adding index cader_id:

class AddCaderIdToJob < ActiveRecord::Migration[5.2]
  def change
    change_table :jobs do |t|
      t.integer :cader_id
      t.index :cader_id
    end
  end
end

You can get MinGW (as others have suggested) but I would recommend getting a simple IDE (not VS Express). You can try Dev C++ http://www.bloodshed.net/devcpp.html Its a simple IDE for C/C++ and uses MinGW internally. In this you can write and compile single C files without creating a full-blown "project".

To calculate the percentile of a series, run:

from scipy.stats import rankdata
import numpy as np

def calc_percentile(a, method='min'):
    if isinstance(a, list):
        a = np.asarray(a)
    return rankdata(a, method=method) / float(len(a))

For example:

a = range(20)
print {val: round(percentile, 3) for val, percentile in zip(a, calc_percentile(a))}
>>> {0: 0.05, 1: 0.1, 2: 0.15, 3: 0.2, 4: 0.25, 5: 0.3, 6: 0.35, 7: 0.4, 8: 0.45, 9: 0.5, 10: 0.55, 11: 0.6, 12: 0.65, 13: 0.7, 14: 0.75, 15: 0.8, 16: 0.85, 17: 0.9, 18: 0.95, 19: 1.0}

Be careful when using milliseconds.

The date.getTime() returns milliseconds and doing math operation with milliseconds requires to include

• Daylight Saving Time (DST)
• checking if both dates have the same time (hours, minutes, seconds, milliseconds)
• make sure what behavior of days diff is required: 19 September 2016 - 29 September 2016 = 1 or 2 days difference?

The example from comment above is the best solution I found so far https://stackoverflow.com/a/11252167/2091095 . But use +1 to its result if you want the to count all days involved.

function treatAsUTC(date) {
    var result = new Date(date);
    result.setMinutes(result.getMinutes() - result.getTimezoneOffset());
    return result;
}

function daysBetween(startDate, endDate) {
    var millisecondsPerDay = 24 * 60 * 60 * 1000;
    return (treatAsUTC(endDate) - treatAsUTC(startDate)) / millisecondsPerDay;
}

var diff = daysBetween($('#first').val(), $('#second').val()) + 1;

One liner:

var object = (Cars)new XmlSerializer(typeof(Cars)).Deserialize(new StringReader(xmlString));

I fixed it by modify my POM file. Notice the last comment under the highest voted answer.

<plugin>
    <artifactId>maven-compiler-plugin</artifactId>

The source must matches the target.

install these ==>> pip install -U scikit-learn scipy matplotlib if still getting the same error then , make sure that your imoprted statment should be correct. i made the mistike while writing ensemble so ,(check spelling) its should be >>> from sklearn.ensemble import RandomForestClassifier

Small additional note to @rmag's answer. If you have empty but required fields that you want to make dirty use this:

$scope.myForm.username.$setViewValue($scope.myForm.username.$viewValue !== undefined 
    ? $scope.myForm.username.$viewValue : '');

Assuming you're the administrator of the machine, Ubuntu has granted you the right to sudo to run any command as any user.
Also assuming you did not restrict the rights in the pg_hba.conf file (in the /etc/postgresql/9.1/main directory), it should contain this line as the first rule:

# Database administrative login by Unix domain socket  
local   all             postgres                                peer

(About the file location: 9.1 is the major postgres version and main the name of your "cluster". It will differ if using a newer version of postgres or non-default names. Use the pg_lsclusters command to obtain this information for your version/system).

Anyway, if the pg_hba.conf file does not have that line, edit the file, add it, and reload the service with sudo service postgresql reload.

Then you should be able to log in with psql as the postgres superuser with this shell command:

sudo -u postgres psql

Once inside psql, issue the SQL command:

ALTER USER postgres PASSWORD 'newpassword';

In this command, postgres is the name of a superuser. If the user whose password is forgotten was ritesh, the command would be:

ALTER USER ritesh PASSWORD 'newpassword';

References: PostgreSQL 9.1.13 Documentation, Chapter 19. Client Authentication

Keep in mind that you need to type postgres with a single S at the end

If leaving the password in clear text in the history of commands or the server log is a problem, psql provides an interactive meta-command to avoid that, as an alternative to ALTER USER ... PASSWORD:

\password username

It asks for the password with a double blind input, then hashes it according to the password_encryption setting and issue the ALTER USER command to the server with the hashed version of the password, instead of the clear text version.

Read this:

http://www.quora.com/OAuth-2-0/How-does-OAuth-2-0-work

or an even simpler but quick explanation:

http://agileanswer.blogspot.se/2012/08/oauth-20-for-my-ninth-grader.html

The redirect URI is the callback entry point of the app. Think about how OAuth for Facebook works - after end user accepts permissions, "something" has to be called by Facebook to get back to the app, and that "something" is the redirect URI. Furthermore, the redirect URI should be different than the initial entry point of the app.

The other key point to this puzzle is that you could launch your app from a URL given to a webview. To do this, i simply followed the guide on here:

http://iosdevelopertips.com/cocoa/launching-your-own-application-via-a-custom-url-scheme.html

and

http://inchoo.net/mobile-development/iphone-development/launching-application-via-url-scheme/

note: on those last 2 links, "http://" works in opening mobile safari but "tel://" doesn't work in simulator

in the first app, I call

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"secondApp://"]];

In my second app, I register "secondApp" (and NOT "secondApp://") as the name of URL Scheme, with my company as the URL identifier.

Is the name of your service class really IService (on the Service namespace)? What you probably had originally was a mismatch in the name of the service class in the name attribute of the <service> element.

The format you need is:

'2007-01-01 10:00:00'

i.e. yyyy-MM-dd HH:mm:ss

If possible, however, use a parameterised query as this frees you from worrying about the formatting details.

outgoing url in mvc generated based on the current routing schema.

because your Information action method require id parameter, and your route collection has id of your current requested url(/Admin/Information/5), id parameter automatically gotten from existing route collection values.

to solve this problem you should use UrlParameter.Optional:

 <a href="@Url.Action("Information", "Admin", new { id = UrlParameter.Optional })">Add an Admin</a>

NOTE

For Android Studio 0.5.5 and later, and with later versions of the Facebook SDK, this process is much simpler than what is documented below (which was written for earlier versions of both). If you're running the latest, all you need to do is this:

1. Download the Facebook SDK from https://developers.facebook.com/docs/android/
2. Unzip the archive
3. In Android Studio 0.5.5 or later, choose "Import Module" from the File menu.
4. In the wizard, set the source path of the module to import as the "facebook" directory inside the unpacked archive. (Note: If you choose the entire parent folder, it will bring in not only the library itself, but also all of the sample apps, each as a separate module. This may work but probably isn't what you want).
5. Open project structure by Ctrl + Shift + Alt + S and then select dependencies tab. Click on + button and select Module Dependency. In the new window pop up select :facebook.
6. You should be good to go.

Instructions for older Android Studio and older Facebook SDK

This applies to Android Studio 0.5.4 and earlier, and makes the most sense for versions of the Facebook SDK before Facebook offered Gradle build files for the distribution. I don't know in which version of the SDK they made that change.

Facebook's instructions under "Import the SDK into an Android Studio Project" on their https://developers.facebook.com/docs/getting-started/facebook-sdk-for-android-using-android-studio/3.0/ page are wrong for Gradle-based projects (i.e. your project was built using Android Studio's New Project wizard and/or has a build.gradle file for your application module). Follow these instructions instead:

1. Create a libraries folder underneath your project's main directory. For example, if your project is HelloWorldProject, you would create a HelloWorldProject/libraries folder.

2. Now copy the entire facebook directory from the SDK installation into the libraries folder you just created.

3. Delete the libs folder in the facebook directory. If you like, delete the project.properties, build.xml, .classpath, and .project. files as well. You don't need them.

4. Create a build.gradle file in the facebook directory with the following contents:

   buildscript {
       repositories {
           mavenCentral()
       }
       dependencies {
           classpath 'com.android.tools.build:gradle:0.6.+'
       }
   }
   
   apply plugin: 'android-library'
   
   dependencies {
       compile 'com.android.support:support-v4:+'
   }
   
   android {
       compileSdkVersion 17
       buildToolsVersion "19.0.0"
   
       defaultConfig {
           minSdkVersion 7
           targetSdkVersion 16
       }
   
       sourceSets {
           main {
               manifest.srcFile 'AndroidManifest.xml'
               java.srcDirs = ['src']
               resources.srcDirs = ['src']
               res.srcDirs = ['res']
           }
       }
   }
   

   Note that depending on when you're following these instructions compared to when this is written, you may need to adjust the classpath 'com.android.tools.build:gradle:0.6.+' line to reference a newer version of the Gradle plugin. Soon we will require version 0.7 or later. Try it out, and if you get an error that a newer version of the Gradle plugin is required, that's the line you have to edit.

5. Make sure the Android Support Library in your SDK manager is installed.

6. Edit your settings.gradle file in your application’s main directory and add this line:

   include ':libraries:facebook'
   

7. If your project is already open in Android Studio, click the "Sync Project with Gradle Files" button in the toolbar. Once it's done, the facebook module should appear.

8. Open the Project Structure dialog. Choose Modules from the left-hand list, click on your application’s module, click on the Dependencies tab, and click on the + button to add a new dependency.
9. Choose “Module dependency”. It will bring up a dialog with a list of modules to choose from; select “:libraries:facebook”.
10. Click OK on all the dialogs. Android Studio will automatically resynchronize your project (making it unnecessary to click that "Sync Project with Gradle Files" button again) and pick up the new dependency. You should be good to go.

Both ItemListener as well as ActionListener, in case of JCheckBox have the same behaviour. However, major difference is ItemListener can be triggered by calling the setSelected(true) on the checkbox. As a coding practice do not register both ItemListener as well as ActionListener with the JCheckBox, in order to avoid inconsistency.

You have a number of options:

One is to not use streams, but use the TextWriter

   void Print(TextWriter writer) 
   {
   }

   void Main() 
  {
    var textWriter = new StringWriter();
    Print(writer);
    string myString = textWriter.ToString();
   }

It's likely that TextWriter is the appropriate level of abstraction for your print function. Streams are aimed at writing binary data, while TextWriter works at a higher abstraction level, specifically geared towards outputting strings.

If your motivation is that you also want your Print function to write to files, you can get a text writer from a filestream as well.

void Print(TextWriter writer) 
{
}

void PrintToFile(string filePath) 
{
     using(var textWriter = new StreamWriter(filePath))
     {
         Print(writer);
     }
}

If you REALLY want a stream you can look at MemoryStream.

I just had the exact same problem and it turned out to be caused by the fact that 2 projects in the same solution were referencing a different version of the 3rd party library.

Once I corrected all the references everything worked perfectly.

Use this query:

ALTER TABLE tablename ADD columname DATATYPE(size);

And here is an example:

ALTER TABLE Customer ADD LastName VARCHAR(50);

The jQuery documentation recommends doing something like the following:

$( document ).ajaxStart(function() {
  $( "#loading" ).show();
}).ajaxStop(function() {
  $( "#loading" ).hide();
});

Where #loading is the element with your busy indicator in it.

References:

• http://api.jquery.com/ajaxStart/

• http://api.jquery.com/ajaxStop/

• In addition, jQuery.ajaxSetup API explicitly recommends avoiding jQuery.ajaxSetup for these:

  Note: Global callback functions should be set with their respective global Ajax event handler methods—.ajaxStart(), .ajaxStop(), .ajaxComplete(), .ajaxError(), .ajaxSuccess(), .ajaxSend()—rather than within the options object for $.ajaxSetup().

I use this approach for drawing a modal overlay.

.fullDiv { width:100%; height:100%; position:fixed }

I believe the distinction here is the use of position:fixed which may or may not be applicable to your use case.

I also add z-index:1000; background:rgba(50,50,50,.7);

Then, the modal content can live inside that div, and any content that was already on the page remains visible in the background but covered by the overlay fully while scrolling.

I don't have Oracle to test it, but the most efficient solution is to use analytic queries. It should look something like this:

SELECT DISTINCT
    UserId
  , MaxValue
FROM (
    SELECT UserId
      , FIRST (Value) Over (
          PARTITION BY UserId
          ORDER BY Date DESC
        ) MaxValue
    FROM SomeTable
  )

I suspect that you can get rid of the outer query and put distinct on the inner, but I'm not sure. In the meantime I know this one works.

If you want to learn about analytic queries, I'd suggest reading http://www.orafaq.com/node/55 and http://www.akadia.com/services/ora_analytic_functions.html. Here is the short summary.

Under the hood analytic queries sort the whole dataset, then process it sequentially. As you process it you partition the dataset according to certain criteria, and then for each row looks at some window (defaults to the first value in the partition to the current row - that default is also the most efficient) and can compute values using a number of analytic functions (the list of which is very similar to the aggregate functions).

In this case here is what the inner query does. The whole dataset is sorted by UserId then Date DESC. Then it processes it in one pass. For each row you return the UserId and the first Date seen for that UserId (since dates are sorted DESC, that's the max date). This gives you your answer with duplicated rows. Then the outer DISTINCT squashes duplicates.

This is not a particularly spectacular example of analytic queries. For a much bigger win consider taking a table of financial receipts and calculating for each user and receipt, a running total of what they paid. Analytic queries solve that efficiently. Other solutions are less efficient. Which is why they are part of the 2003 SQL standard. (Unfortunately Postgres doesn't have them yet. Grrr...)

If you prefer to use a library, use ts-essentials.

import { Omit } from "ts-essentials";

type ComplexObject = {
  simple: number;
  nested: {
    a: string;
    array: [{ bar: number }];
  };
};

type SimplifiedComplexObject = Omit<ComplexObject, "nested">;

// Result:
// {
//  simple: number
// }

// if you want to Omit multiple properties just use union type:
type SimplifiedComplexObject = Omit<ComplexObject, "nested" | "simple">;

// Result:
// { } (empty type)

PS: You will find lots of other useful stuff there ;)

You can just use the + operator!

irb(main):001:0> a = [1,2]
=> [1, 2]
irb(main):002:0> b = [3,4]
=> [3, 4]
irb(main):003:0> a + b
=> [1, 2, 3, 4]

You can read all about the array class here: http://ruby-doc.org/core/classes/Array.html

Well, the error is pretty clear, no? You are trying to connect to your SQL Server with user "xyz/ASPNET" - that's the account your ASP.NET app is running under.

This account is not allowed to connect to SQL Server - either create a login on SQL Server for that account, or then specify another valid SQL Server account in your connection string.

Can you show us your connection string (by updating your original question)?

UPDATE: Ok, you're using integrated Windows authentication --> you need to create a SQL Server login for "xyz\ASPNET" on your SQL Server - or change your connection string to something like:

connectionString="Server=.\SQLExpress;Database=IFItest;User ID=xyz;pwd=top$secret"

If you have a user "xyz" with a password of "top$secret" in your database.

The parameters of isset() should be separated by a comma sign (,) and not a dot sign (.). Your current code concatenates the variables into a single parameter, instead of passing them as separate parameters.

So the original code evaluates the variables as a unified string value:

isset($_POST['search_term'] . $_POST['postcode']) // Incorrect

While the correct form evaluates them separately as variables:

isset($_POST['search_term'], $_POST['postcode']) // Correct

I’ve run into this problem too. Another solution is to toggle the SELinux boolean value for httpd network connect to on (Nginx uses the httpd label).

setsebool httpd_can_network_connect on

To make the change persist use the -P flag.

setsebool httpd_can_network_connect on -P

You can see a list of all available SELinux booleans for httpd using

getsebool -a | grep httpd

1. First activate your conda environment (the one u want to export/backup)

conda activate myEnv

2. Export all packages to a file (myEnvBkp.txt)

conda list --explicit > myEnvBkp.txt

3. Restore/import the environment:

conda create --name myEnvRestored --file myEnvBkp.txt

The latest version of .Net (v4.6) just added built-in support for Unix time conversions. That includes both to and from Unix time represented by either seconds or milliseconds.

• Unix time in seconds to DateTimeOffset:

DateTimeOffset dateTimeOffset = DateTimeOffset.FromUnixTimeSeconds(1000);

• DateTimeOffset to Unix time in seconds:

long unixTimeStampInSeconds = dateTimeOffset.ToUnixTimeSeconds();

• Unix time in milliseconds to DateTimeOffset:

DateTimeOffset dateTimeOffset = DateTimeOffset.FromUnixTimeMilliseconds(1000000);

• DateTimeOffset to Unix time in milliseconds:

long unixTimeStampInMilliseconds= dateTimeOffset.ToUnixTimeMilliseconds();

Note: These methods convert to and from DateTimeOffset. To get a DateTime representation simply use the DateTimeOffset.DateTime property:

DateTime dateTime = dateTimeOffset.UtcDateTime;

you can use the DomDocument method to get an individual HTML tag level variable too

$homepage = file_get_contents('https://www.example.com/');
$doc = new DOMDocument;
$doc->loadHTML($homepage);
$titles = $doc->getElementsByTagName('h3');
echo $titles->item(0)->nodeValue;

The brackets that are commonly used in the mysql documentation for examples should be ommitted in a 'real' query.

It also doesn't appear that you're echoing the result of the mysql query anywhere. mysql_query returns a mysql resource on success. The php manual page also includes instructions on how to load the mysql result resource into an array for echoing and other manipulation.

I've experienced problems with large sqlite files when using the vacuum command.

I haven't tried the auto_vacuum feature yet. If you expect to be updating and deleting data often then this is worth looking at.

You need to call srand() once, to randomize the seed, and then call rand() in your loop:

#include <stdlib.h>
#include <time.h>

#define size 10

srand(time(NULL)); // randomize seed

for(i=0;i<size;i++)
    Arr[i] = rand()%size;

 @Html.TextBox("Receivers", Model, new { @class = "form-control", style = "width: 300px", @readonly = "readonly" })

grid.Columns[0].HeaderText

or

grid.Columns["columnname"].HeaderText

Pickle serializes a single object at a time, and reads back a single object - the pickled data is recorded in sequence on the file.

If you simply do pickle.load you should be reading the first object serialized into the file (not the last one as you've written).

After unserializing the first object, the file-pointer is at the beggining of the next object - if you simply call pickle.load again, it will read that next object - do that until the end of the file.

objects = []
with (open("myfile", "rb")) as openfile:
    while True:
        try:
            objects.append(pickle.load(openfile))
        except EOFError:
            break

As you correctly point out, one can ReDim Preserve only the last dimension of an array (ReDim Statement on MSDN):

If you use the Preserve keyword, you can resize only the last array dimension and you can't change the number of dimensions at all. For example, if your array has only one dimension, you can resize that dimension because it is the last and only dimension. However, if your array has two or more dimensions, you can change the size of only the last dimension and still preserve the contents of the array

Hence, the first issue to decide is whether 2-dimensional array is the best data structure for the job. Maybe, 1-dimensional array is a better fit as you need to do ReDim Preserve?

Another way is to use jagged array as per Pieter Geerkens's suggestion. There is no direct support for jagged arrays in VB6. One way to code "array of arrays" in VB6 is to declare an array of Variant and make each element an array of desired type (String in your case). Demo code is below.

Yet another option is to implement Preserve part on your own. For that you'll need to create a copy of data to be preserved and then fill redimensioned array with it.

Option Explicit

    For i = 0 To n - 1
        StringArray = a(i)
        ReDim Preserve StringArray(m)
        a(i) = StringArray
    Next i
    ReDim StringArray(m)
    a(n) = StringArray
End Sub

The line (or lines) between the lines beginning <<<<<<< and ====== here:

<<<<<<< HEAD:file.txt
Hello world
=======

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

You need to alias the subquery.

SELECT name FROM (SELECT name FROM agentinformation) a  

or to be more explicit

SELECT a.name FROM (SELECT name FROM agentinformation) a  

On a linux server you can just use this commands to reconfigure Tomcat to listen on port 80:

service tomcat8 restart

While building the project on Unix/Linux platform, set Maven options syntax as below. Notice that single qoutation signs, not double qoutation.

What I found out is that MS Access will reject --Not Like "BB*"-- if not enclosed in PARENTHESES, unlike --Like "BB*"-- which is ok without parentheses.

I tested these on MS Access 2010 and are all valid:

1. Like "BB"

2. (Like "BB")

3. (Not Like "BB")

You can have more than one statement when still return:

For me, after trying all above solutions it ended up being a problem related to encoding. Concisely, my key was encoded using 'UTF-8 with BOM'. It should be UTF-8 instead.

To fix it, at least using VS Code follow this steps:

1. Open the file and click on the encoding button at the status bar (at the bottom) and select 'Save with encoding'.
2. Select UTF-8.
3. Then try using the certificate again.

I suppose you can use other editors that support saving with the proper encoding.

Source: error:0906d06c:pem routines:pem_read_bio:no start line, when importing godaddy SSL certificate

P.D I did not need to set the encoding to utf-8 option when loading the file using the fs.readFileSync function.

Hope this helps somebody!

The last parameter to the rgba() function is the "alpha" or "opacity" parameter. If you set it to 0 it will mean "completely transparent", and the first three parameters (the red, green, and blue channels) won't matter because you won't be able to see the color anyway.

With that in mind, I would choose rgba(0, 0, 0, 0) because:

1. it's less typing,
2. it keeps a few extra bytes out of your CSS file, and
3. you will see an obvious problem if the alpha value changes to something undesirable.

You could avoid the rgba model altogether and use the transparent keyword instead, which according to w3.org, is equivalent to "transparent black" and should compute to rgba(0, 0, 0, 0). For example:

h1 {
    background-color: transparent;
}

This saves you yet another couple bytes while your intentions of using transparency are obvious (in case one is unfamiliar with RGBA).

As of CSS3, you can use the transparent keyword for any CSS property that accepts a color.

To get the moving average in pandas we can use cum_sum and then divide by count.

Here is the working example:

import pandas as pd
import numpy as np

df = pd.DataFrame({'id': range(5),
                   'value': range(100,600,100)})

# some other similar statistics
df['cum_sum'] = df['value'].cumsum()
df['count'] = range(1,len(df['value'])+1)
df['mov_avg'] = df['cum_sum'] / df['count']

# other statistics
df['rolling_mean2'] = df['value'].rolling(window=2).mean()

print(df)

output

   id  value  cum_sum  count  mov_avg     rolling_mean2
0   0    100      100      1    100.0           NaN
1   1    200      300      2    150.0           150.0
2   2    300      600      3    200.0           250.0
3   3    400     1000      4    250.0           350.0
4   4    500     1500      5    300.0           450.0

I combined a few options to support FireFox, IE and Chrome. I've also updated it to better support mac

// simply disables save event for chrome
$(window).keypress(function (event) {
    if (!(event.which == 115 && (navigator.platform.match("Mac") ? event.metaKey : event.ctrlKey)) && !(event.which == 19)) return true;
    event.preventDefault();
    return false;
});

// used to process the cmd+s and ctrl+s events
$(document).keydown(function (event) {
     if (event.which == 83 && (navigator.platform.match("Mac") ? event.metaKey : event.ctrlKey)) {
        event.preventDefault();
        save(event);
        return false;
     }
});

I agree, it's more like an 'elif not [condition(s) raising break]'.

I know this is an old thread, but I am looking into the same question right now, and I'm not sure anyone has captured the answer to this question in the way I understand it.

For me, there are three ways of "reading" the else in For... else or While... else statements, all of which are equivalent, are:

1. else == if the loop completes normally (without a break or error)
2. else == if the loop does not encounter a break
3. else == else not (condition raising break) (presumably there is such a condition, or you wouldn't have a loop)

So, essentially, the "else" in a loop is really an "elif ..." where '...' is (1) no break, which is equivalent to (2) NOT [condition(s) raising break].

I think the key is that the else is pointless without the 'break', so a for...else includes:

for:
    do stuff
    conditional break # implied by else
else not break:
    do more stuff

So, essential elements of a for...else loop are as follows, and you would read them in plainer English as:

for:
    do stuff
    condition:
        break
else: # read as "else not break" or "else not condition"
    do more stuff

As the other posters have said, a break is generally raised when you are able to locate what your loop is looking for, so the else: becomes "what to do if target item not located".

Example

You can also use exception handling, breaks, and for loops all together.

for x in range(0,3):
    print("x: {}".format(x))
    if x == 2:
        try:
            raise AssertionError("ASSERTION ERROR: x is {}".format(x))
        except:
            print(AssertionError("ASSERTION ERROR: x is {}".format(x)))
            break
else:
    print("X loop complete without error")

Result

x: 0
x: 1
x: 2
ASSERTION ERROR: x is 2
----------
# loop not completed (hit break), so else didn't run

Example

Simple example with a break being hit.

for y in range(0,3):
    print("y: {}".format(y))
    if y == 2: # will be executed
        print("BREAK: y is {}\n----------".format(y))
        break
else: # not executed because break is hit
    print("y_loop completed without break----------\n")

Result

y: 0
y: 1
y: 2
BREAK: y is 2
----------
# loop not completed (hit break), so else didn't run

Example

Simple example where there no break, no condition raising a break, and no error are encountered.

for z in range(0,3):
     print("z: {}".format(z))
     if z == 4: # will not be executed
         print("BREAK: z is {}\n".format(y))
         break
     if z == 4: # will not be executed
         raise AssertionError("ASSERTION ERROR: x is {}".format(x))
else:
     print("z_loop complete without break or error\n----------\n")

Result

z: 0
z: 1
z: 2
z_loop complete without break or error

The common scenario is the following: I forgot to create the new branch for the new feature, and was doing all the work in the old feature branch. I have commited all the "old" work to the master branch, and I want my new branch to grow from the "master". I have not made a single commit of my new work. Here is the branch structure: "master"->"Old_feature"

git stash 
git checkout master
git checkout -b "New_branch"
git stash apply

I found it much easier to debut by printing out where each row meets the condition:

for n in df.columns:
    if(np.where(df[n] == 103)):
        print(n)
        print(df[df[n] == 103].index)

I agree with somebody's recently deleted post that the differences in performance are so small that, with very very few exceptions, (he got dinged for saying never) you should not make your design decision based upon that.

In your example, where the elements are Objects, the performance difference should be minimal.

If you are dealing with a large number of primitives, an array will offer significantly better performance, both in memory and time.

The answer has been covered, but for simplicity...

# To filter out finished threads
threads = [t for t in threads if t.is_alive()]

# Same thing but for QThreads (if you are using PyQt)
threads = [t for t in threads if t.isRunning()]

If you don't care about the columns where the missing files are, considering that the dataframe has the name New and one wants to assign the new dataframe to the same variable, simply run

New = New.drop_duplicates()

If you specifically want to remove the rows for the empty values in the column Tenant this will do the work

New = New[New.Tenant != '']

This may also be used for removing rows with a specific value - just change the string to the value that one wants.

Note: If instead of an empty string one has NaN, then

New = New.dropna(subset=['Tenant'])

For same table,

UPDATE PHA_BILL_SEGMENT AS PHA,
     (SELECT BILL_ID, COUNT(REGISTRATION_NUMBER) AS REG 
       FROM PHA_BILL_SEGMENT
        GROUP BY REGISTRATION_NUMBER, BILL_DATE, BILL_AMOUNT
        HAVING REG > 1) T
    SET PHA.BILL_DATE = PHA.BILL_DATE + 2
 WHERE PHA.BILL_ID = T.BILL_ID;

There's no dedicated "character type" in C language. char is an integer type, same (in that regard) as int, short and other integer types. char just happens to be the smallest integer type. So, just like any other integer type, it can be signed or unsigned.

It is true that (as the name suggests) char is mostly intended to be used to represent characters. But characters in C are represented by their integer "codes", so there's nothing unusual in the fact that an integer type char is used to serve that purpose.

The only general difference between char and other integer types is that plain char is not synonymous with signed char, while with other integer types the signed modifier is optional/implied.

For what it's worth, here's my .bash_profile, that works well for me on a mac with Atom, after installing go with Homebrew:

export GOROOT=`go env GOROOT`
export GOPATH=/Users/yy/Projects/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOBIN

function stringToBool($string){
    return ( mb_strtoupper( trim( $string)) === mb_strtoupper ("true")) ? TRUE : FALSE;
}

or

function stringToBool($string) {
    return filter_var($string, FILTER_VALIDATE_BOOLEAN);
}

Try it too, this does not take in account browser version.

function mode(arr){
var a = [],b = 0,occurrence;
    for(var i = 0; i < arr.length;i++){
    if(a[arr[i]] != undefined){
        a[arr[i]]++;
    }else{
        a[arr[i]] = 1;
    }
    }
    for(var key in a){
    if(a[key] > b){
        b = a[key];
        occurrence = key;
    }
    }
return occurrence;
}
alert(mode(['segunda','terça','terca','segunda','terça','segunda']));

Please note that this function returns latest occurence in the array when 2 or more entries appear same number of times!

'' encloses single char, while "" encloses a String.

Change

y = 'hello';

-->

The bitwise shift operators move the bit values of a binary object. The left operand specifies the value to be shifted. The right operand specifies the number of positions that the bits in the value are to be shifted. The result is not an lvalue. Both operands have the same precedence and are left-to-right associative.

Operator     Usage

 <<           Indicates the bits are to be shifted to the left.

 >>           Indicates the bits are to be shifted to the right.

Each operand must have an integral or enumeration type. The compiler performs integral promotions on the operands, and then the right operand is converted to type int. The result has the same type as the left operand (after the arithmetic conversions).

The right operand should not have a negative value or a value that is greater than or equal to the width in bits of the expression being shifted. The result of bitwise shifts on such values is unpredictable.

If the right operand has the value 0, the result is the value of the left operand (after the usual arithmetic conversions).

The << operator fills vacated bits with zeros. For example, if left_op has the value 4019, the bit pattern (in 16-bit format) of left_op is:

0000111110110011

The expression left_op << 3 yields:

0111110110011000

The expression left_op >> 3 yields:

0000000111110110

If you want to get unique data based on the nested key:

app.filter('unique', function() {
        return function(collection, primaryKey, secondaryKey) { //optional secondary key
          var output = [], 
              keys = [];

          angular.forEach(collection, function(item) {
                var key;
                secondaryKey === undefined ? key = item[primaryKey] : key = item[primaryKey][secondaryKey];

                if(keys.indexOf(key) === -1) {
                  keys.push(key);
                  output.push(item);
                }
          });

          return output;
        };
    });

Call it like this :

Yes this is possible. kizzie is correct with the session_start(); having to go first.

another observation I made is that you need to filter your form data using:

strip_tags($value);

and/or

stripslashes($value);

For me, such tags are enabled by default. You can configure which task tags should be used in the workspace options: Java > Compiler > Task tags

Check if they are enabled in this location, and that should be enough to have them appear in the Task list (or the Markers view).

Extra note: reinstalling Eclipse won't change anything most of the time if you work on the same workspace. Most settings used by Eclipse are stored in the .metadata folder, in your workspace folder.

JavaScript is single threaded and has a synchronous execution model. Single threaded means that one command is being executed at a time. Synchronous means one at a time i.e. one line of code is being executed at time in order the code appears. So in JavaScript one thing is happening at a time.

Execution Context

The JavaScript engine interacts with other engines in the browser. In the JavaScript execution stack there is global context at the bottom and then when we invoke functions the JavaScript engine creates new execution contexts for respective functions. When the called function exits its execution context is popped from the stack, and then next execution context is popped and so on...

For example

function abc()
{
   console.log('abc');
}


function xyz()
{
   abc()
   console.log('xyz');
}
var one = 1;
xyz();

In the above code a global execution context will be created and in this context var one will be stored and its value will be 1... when the xyz() invocation is called then a new execution context will be created and if we had defined any variable in xyz function those variables would be stored in the execution context of xyz(). In the xyz function we invoke abc() and then the abc() execution context is created and put on the execution stack... Now when abc() finishes its context is popped from stack, then the xyz() context is popped from stack and then global context will be popped...

Now about asynchronous callbacks; asynchronous means more than one at a time.

Just like the execution stack there is the Event Queue. When we want to be notified about some event in the JavaScript engine we can listen to that event, and that event is placed on the queue. For example an Ajax request event, or HTTP request event.

Whenever the execution stack is empty, like shown in above code example, the JavaScript engine periodically looks at the event queue and sees if there is any event to be notified about. For example in the queue there were two events, an ajax request and a HTTP request. It also looks to see if there is a function which needs to be run on that event trigger... So the JavaScript engine is notified about the event and knows the respective function to execute on that event... So the JavaScript engine invokes the handler function, in the example case, e.g. AjaxHandler() will be invoked and like always when a function is invoked its execution context is placed on the execution context and now the function execution finishes and the event ajax request is also removed from the event queue... When AjaxHandler() finishes the execution stack is empty so the engine again looks at the event queue and runs the event handler function of HTTP request which was next in queue. It is important to remember that the event queue is processed only when execution stack is empty.

For example see the code below explaining the execution stack and event queue handling by Javascript engine.

function waitfunction() {
    var a = 5000 + new Date().getTime();
    while (new Date() < a){}
    console.log('waitfunction() context will be popped after this line');
}

function clickHandler() {
    console.log('click event handler...');   
}

document.addEventListener('click', clickHandler);


waitfunction(); //a new context for this function is created and placed on the execution stack
console.log('global context will be popped after this line');

And

<html>
    <head>

    </head>
    <body>

        <script src="program.js"></script>
    </body>
</html>

Now run the webpage and click on the page, and see the output on console. The output will be

waitfunction() context will be popped after this line
global context will be emptied after this line
click event handler...

The JavaScript engine is running the code synchronously as explained in the execution context portion, the browser is asynchronously putting things in event queue. So the functions which take a very long time to complete can interrupt event handling. Things happening in a browser like events are handled this way by JavaScript, if there is a listener supposed to run, the engine will run it when the execution stack is empty. And events are processed in the order they happen, so the asynchronous part is about what is happening outside the engine i.e. what should the engine do when those outside events happen.

So JavaScript is always synchronous.

Let me add another solution without using third-party libraries. It re-uses an exception handling pattern that was proposed by Scott (link). And I moved the ugly part into a separate message (I would hide in some FileUtils class ;) )

public void someMethod() {
    final byte[] buffer = read(new File("test.txt"));
}

private byte[] read(final File file) {
    if (file.isDirectory())
        throw new RuntimeException("Unsupported operation, file "
                + file.getAbsolutePath() + " is a directory");
    if (file.length() > Integer.MAX_VALUE)
        throw new RuntimeException("Unsupported operation, file "
                + file.getAbsolutePath() + " is too big");

    Throwable pending = null;
    FileInputStream in = null;
    final byte buffer[] = new byte[(int) file.length()];
    try {
        in = new FileInputStream(file);
        in.read(buffer);
    } catch (Exception e) {
        pending = new RuntimeException("Exception occured on reading file "
                + file.getAbsolutePath(), e);
    } finally {
        if (in != null) {
            try {
                in.close();
            } catch (Exception e) {
                if (pending == null) {
                    pending = new RuntimeException(
                        "Exception occured on closing file" 
                             + file.getAbsolutePath(), e);
                }
            }
        }
        if (pending != null) {
            throw new RuntimeException(pending);
        }
    }
    return buffer;
}

If you write an unmanaged program and use CreateProcess API then you should initialize lpStartupInfo parameter of the type STARTUPINFO so that wShowWindow field of the struct is SW_HIDE and not forget to use STARTF_USESHOWWINDOW flag in the dwFlags field of STARTUPINFO. Another method is to use CREATE_NO_WINDOW flag of dwCreationFlags parameter. The same trick work also with ShellExecute and ShellExecuteEx functions.

If you write a managed application you should follows advices from http://blogs.msdn.com/b/jmstall/archive/2006/09/28/createnowindow.aspx: initialize ProcessStartInfo with CreateNoWindow = true and UseShellExecute = false and then use as a parameter of . Exactly like in case of you can set property WindowStyle of ProcessStartInfo to ProcessWindowStyle.Hidden instead or together with CreateNoWindow = true.

You can use a VBS script which you start with wcsript.exe. Inside the script you can use CreateObject("WScript.Shell") and then Run with 0 as the second (intWindowStyle) parameter. See http://www.robvanderwoude.com/files/runnhide_vbs.txt as an example. I can continue with Kix, PowerShell and so on.

If you don't want to write any program you can use any existing utility like CMDOW /RUN /HID "c:\SomeDir\MyBatch.cmd", hstart /NOWINDOW /D=c:\scripts "c:\scripts\mybatch.bat", hstart /NOCONSOLE "batch_file_1.bat" which do exactly the same. I am sure that you will find much more such kind of free utilities.

In some scenario (for example starting from UNC path) it is important to set also a working directory to some local path (%SystemRoot%\system32 work always). This can be important for usage any from above listed variants of starting hidden batch.

You can use the change event to monitor what the user selects and notify them at that point that the file is not acceptable. It does not limit the actual list of files displayed, but it is the closest you can do client-side, besides the poorly supported accept attribute.

var file = document.getElementById('someId');_x000D_
_x000D_
file.onchange = function(e) {_x000D_
  var ext = this.value.match(/\.([^\.]+)$/)[1];_x000D_
  switch (ext) {_x000D_
    case 'jpg':_x000D_
    case 'bmp':_x000D_

I happened to encounter a similar kind of issue after setting up local internal JFrog Docker Private Registry on Amazon Linux.

THE followings I did to solve the issue:

Added "--insecure-registry xx.xx.xx.xx:8081" by modifying the OPTIONS variable in the /etc/sysconfig/docker file:

OPTIONS="--default-ulimit nofile=1024:40961 --insecure-registry hostname:8081"

Then restarted the docker.

I was then able to login to the local docker registry using:

docker login -u admin -p password hostname:8081

I think the documentation is reasonably helpful!

If you read it again, it says that adding open graph elements on your website will make your website act as a facebook page and you'll get the ability to publish updates to them etc.

So I think it's up to you - you can either just have a page with no OG elements, which is less work but also less 'rewarding' for you.

If you do use og, then set type to: blog

Finally: fb:admins or fb:app_id - A comma-separated list of either the Facebook IDs of page administrators or a Facebook Platform application ID. At a minimum, include only your own Facebook ID.

So just put your own fbid in there. As a tip, you can easily get this by looking at the url of your profile photo on facebook.

Try this:

import re

mystr = 'This is a string, with words!'
wordList = re.sub("[^\w]", " ",  mystr).split()

How it works:

From the docs :

re.sub(pattern, repl, string, count=0, flags=0)

Return the string obtained by replacing the leftmost non-overlapping occurrences of pattern in string by the replacement repl. If the pattern isn’t found, string is returned unchanged. repl can be a string or a function.

so in our case :

pattern is any non-alphanumeric character.

[\w] means any alphanumeric character and is equal to the character set [a-zA-Z0-9_]

a to z, A to Z , 0 to 9 and underscore.

so we match any non-alphanumeric character and replace it with a space .

and then we split() it which splits string by space and converts it to a list

so 'hello-world'

becomes 'hello world'

with re.sub

and then ['hello' , 'world']

after split()

let me know if any doubts come up.

Just omit the [Required] attribute from the string somefield property. This will make it create a NULLable column in the db.

To make int types allow NULLs in the database, they must be declared as nullable ints in the model:

// an int can never be null, so it will be created as NOT NULL in db
public int someintfield { get; set; }

// to have a nullable int, you need to declare it as an int?
// or as a System.Nullable<int>
public int? somenullableintfield { get; set; }
public System.Nullable<int> someothernullableintfield { get; set; }

Use NodePort:

$ kubectl run user-login --replicas=2 --labels="run=user-login" --image=kingslayerr/teamproject:version2  --port=5000

$ kubectl expose deployment user-login --type=NodePort --name=user-login-service

$ kubectl describe services user-login-service

(Note down the port)

$ kubectl cluster-info

(IP-> Get The IP where master is running)

Your service is accessible at (IP):(port)

Yes, It is required to add libraries after the source files/objects files. This command will solve the problem:

The return statement you have is stuck in the inner function, so it won't return from the outer function. You just need a little more code:

function getMachine(color, qty) {
    var returnValue = null;
    $("#getMachine li").each(function() {
        var thisArray = $(this).text().split("~");
        if(thisArray[0] == color&& qty>= parseInt(thisArray[1]) && qty<= parseInt(thisArray[2])) {
            returnValue = thisArray[3];
            return false; // this breaks out of the each
        }
    });
    return returnValue;
}

var retval = getMachine(color, qty);

Try this

$_SERVER['HTTP_CF_CONNECTING_IP'];

instead of

$_SERVER["REMOTE_ADDR"];

Summary:

The new keyword is used in javascript to create a object from a constructor function. The new keyword has to be placed before the constructor function call and will do the following things:

1. Creates a new object
2. Sets the prototype of this object to the constructor function's prototype property
3. Binds the this keyword to the newly created object and executes the constructor function
4. Returns the newly created object

Example:

function Dog (age) {
  this.age = age;
}

const doggie = new Dog(12);

console.log(doggie);
console.log(Object.getPrototypeOf(doggie) === Dog.prototype) // true

What exactly happens:

1. const doggie says: We need memory for declaring a variable.
2. The assigment operator = says: We are going to initialize this variable with the expression after the =
3. The expression is new Dog(12). The JS engine sees the new keyword, creates a new object and sets the prototype to Dog.prototype
4. The constructor function is executed with the this value set to the new object. In this step is where the age is assigned to the new created doggie object.
5. The newly created object is returned and assigned to the variable doggie.

UPDATED: The problem is pretty common here is the new fix npm cache verify run that you will be good to go!

According to the docs for v0.18.0, if you're running on a terminal (ie not iPython notebook, qtconsole or IDLE), it's a 2-liner to have Pandas auto-detect your screen width and adapt on the fly with how many columns it shows:

pd.set_option('display.large_repr', 'truncate')
pd.set_option('display.max_columns', 0)

Assuming your field is a date type (or similar):

SELECT DATE_ADD(`your_field_name`, INTERVAL 2 DAY) 
FROM `table_name`;

With the example you've provided it could look like this:

UPDATE classes 
SET `date` = DATE_ADD(`date` , INTERVAL 2 DAY)
WHERE `id` = 161;

This approach works with datetime , too.

Proceed like that :

Make a dump of your database first

Remove the primary key like that

ALTER TABLE yourtable DROP PRIMARY KEY

Add the new column like that

ALTER TABLE yourtable add column Id INT NOT NULL AUTO_INCREMENT FIRST, ADD primary KEY Id(Id)

The table will be looked and the AutoInc updated.

Well, apparently this is just not possible without using a JNI to register a plugin to get the video event. (Personally, I am avoiding JNI's since I really don't want to deal with a mess when Atom-based android tablets come out in the next few months, losing the portability of Java.)

The only real alternative seems to be to create a new web page just for WebView and do video the old-school way with an A HREF link as cited in the Codelark url above.

         ON ProductReviews.pid = products.id
WHERE  ProductReviews.id = '17190'
       AND products.shopkeeper = '89137'

HTML (no change)

<div class="top-scroll-wrapper">
    <div class="top-scroll"></div>
</div>

CSS (no change, width: 90% is my desing)

.top-scroll-wrapper { width: 90%;height: 20px;margin: auto;padding: 0 16px;overflow-x: auto;overflow-y: hidden;}
.top-scroll { height: 20px; }

JS (like onload) or ngAfterViewChecked (all the as are for TypeScript)

let $topscroll = document.querySelector(".top-scroll") as HTMLElement
let $topscrollWrapper = document.querySelector(".top-scroll-wrapper") as HTMLElement
let $table = document.querySelectorAll('mat-card')[3] as HTMLElement

$topscroll.style.width = totalWidth + 'px'
$topscrollWrapper.onscroll = e => $table.scroll((e.target as HTMLElement).scrollLeft, 0)
$table.onscroll = e => $topscrollWrapper.scroll((e.target as HTMLElement).scrollLeft, 0)

If you use a TextField with rounded corners use this code:

    self.TextField.layer.cornerRadius=8.0f;
    self.TextField.layer.masksToBounds=YES;
    self.TextField.layer.borderColor=[[UIColor redColor]CGColor];
    self.TextField.layer.borderWidth= 1.0f;

To remove the border:

self.TextField.layer.masksToBounds=NO;
self.TextField.layer.borderColor=[[UIColor clearColor]CGColor];

For this problem,

What i did is:

• Delete the Pids folder which is located under app/tmp/

• and then, close the terminal which we are running the current app and close the tab (in, browser window)

• after that, again open the terminal by going inside the folder, and then do, rails s

• Then, it opens the fresh tab which is running our application

I wrote small library ssl-utils-android to trust particular certificate on Android.

You can simply load any certificate by giving the filename from assets directory.

client.setSslSocketFactory(sslContext.getSocketFactory());

The max-height solution from Jake works well, if the hard-coded max-height value supplied is not much bigger than the real height (because otherwise there are undesirable delays and timing problems). On the other hand if the hard-coded value accidentially is not bigger than the real height the element won't open up completely.

The following CSS only solution also requires a hard-coded size that should be bigger than most of the occurring real sizes. However this solution also works if the real size is in some situations bigger than the hard-coded size. In that event the transition might jump a bit, but it will never leave a partially visible element. So this solution could also be used for unknown content, e.g. from a database, where you just know that the content is usually not bigger than x pixels, but there are exceptions.

Idea is to use a negative value for margin-bottom (or margin-top for a slightly diffenrent animation) and to place the content element into a middle element with overflow:hidden. The negative margin of the content element so reduces the height of the middle element.

The following code uses a transition on margin-bottom from -150px to 0px. This alone works fine as long as the content element is not higher than 150px. In addition it uses a transition on max-height for the middle element from 0px to 100%. This finally hides the middle element if the content element is higher than 150px. For max-height the transition is just used to delay its application by a second when closing, not for a smooth visiual effect ( and therefore it can run from 0px to 100%).

CSS:

.content {
  transition: margin-bottom 1s ease-in;
  margin-bottom: -150px;
}
.outer:hover .middle .content {
  transition: margin-bottom 1s ease-out;
  margin-bottom: 0px
}
.middle {
  overflow: hidden;
  transition: max-height .1s ease 1s;
  max-height: 0px
}
.outer:hover .middle {
  transition: max-height .1s ease 0s;
  max-height: 100%
}

HTML:

<div class="outer">
  <div class="middle">
    <div class="content">
      Sample Text
      <br> Sample Text
      <br> Sample Text
      <div style="height:150px">Sample Test of height 150px</div>
      Sample Text
    </div>
  </div>
  Hover Here
</div>

The value for margin bottom should be negative and as close as possible to the real height of the content element. If it('s absoute value) is bigger there are similar delay and timing problems as with the max-height solutions, which however can be limited as long as the hard coded size is not much bigger than the real one. If the absolute value for margin-bottom is smaller than the real height the tansition jumps a bit. In any case after the transition the content element is either fully displayed or fully removed.

For more details see my blog post http://www.taccgl.org/blog/css_transition_display.html#combined_height

You cannot create a process in linux that cannot be killed. The root user (uid=0) can send a signal to a process, and there are two signals which cannot be caught, SIGKILL=9, SIGSTOP=19. And other signals (when uncaught) can also result in process termination.

You may want a more general daemonize function, where you can specify a name for your program/daemon, and a path to run your program (perhaps "/" or "/tmp"). You may also want to provide file(s) for stderr and stdout (and possibly a control path using stdin).

Here are the necessary includes:

#include <stdio.h>    //printf(3)
#include <stdlib.h>   //exit(3)
#include <unistd.h>   //fork(3), chdir(3), sysconf(3)
#include <signal.h>   //signal(3)
#include <sys/stat.h> //umask(3)
#include <syslog.h>   //syslog(3), openlog(3), closelog(3)

And here is a more general function,

int
daemonize(char* name, char* path, char* outfile, char* errfile, char* infile )
{
    if(!path) { path="/"; }
    if(!name) { name="medaemon"; }
    if(!infile) { infile="/dev/null"; }
    if(!outfile) { outfile="/dev/null"; }
    if(!errfile) { errfile="/dev/null"; }
    //printf("%s %s %s %s\n",name,path,outfile,infile);
    pid_t child;
    //fork, detach from process group leader
    if( (child=fork())<0 ) { //failed fork
        fprintf(stderr,"error: failed fork\n");
        exit(EXIT_FAILURE);
    }
    if (child>0) { //parent
        exit(EXIT_SUCCESS);
    }
    if( setsid()<0 ) { //failed to become session leader
        fprintf(stderr,"error: failed setsid\n");
        exit(EXIT_FAILURE);
    }

    //catch/ignore signals
    signal(SIGCHLD,SIG_IGN);
    signal(SIGHUP,SIG_IGN);

    //fork second time
    if ( (child=fork())<0) { //failed fork
        fprintf(stderr,"error: failed fork\n");
        exit(EXIT_FAILURE);
    }
    if( child>0 ) { //parent
        exit(EXIT_SUCCESS);
    }

    //new file permissions
    umask(0);
    //change to path directory
    chdir(path);

    //Close all open file descriptors
    int fd;
    for( fd=sysconf(_SC_OPEN_MAX); fd>0; --fd )
    {
        close(fd);
    }

    //reopen stdin, stdout, stderr
    stdin=fopen(infile,"r");   //fd=0
    stdout=fopen(outfile,"w+");  //fd=1
    stderr=fopen(errfile,"w+");  //fd=2

    //open syslog
    openlog(name,LOG_PID,LOG_DAEMON);
    return(0);
}

Here is a sample program, which becomes a daemon, hangs around, and then leaves.

int
main()
{
    int res;
    int ttl=120;
    int delay=5;
    if( (res=daemonize("mydaemon","/tmp",NULL,NULL,NULL)) != 0 ) {
        fprintf(stderr,"error: daemonize failed\n");
        exit(EXIT_FAILURE);
    }
    while( ttl>0 ) {
        //daemon code here
        syslog(LOG_NOTICE,"daemon ttl %d",ttl);
        sleep(delay);
        ttl-=delay;
    }
    syslog(LOG_NOTICE,"daemon ttl expired");
    closelog();
    return(EXIT_SUCCESS);
}

Note that SIG_IGN indicates to catch and ignore the signal. You could build a signal handler that can log signal receipt, and set flags (such as a flag to indicate graceful shutdown).

A simpler approach relies on redirection from the page LOGIN_REDIRECT_URL. The key thing to realize is that the user information is automatically included in the request.

Suppose:

LOGIN_REDIRECT_URL = '/profiles/home'

and you have configured a urlpattern:

(r'^profiles/home', home),

Then, all you need to write for the view home() is:

from django.http import HttpResponseRedirect
from django.urls import reverse
from django.contrib.auth.decorators import login_required

@login_required
def home(request):
    return HttpResponseRedirect(
               reverse(NAME_OF_PROFILE_VIEW, 
                       args=[request.user.username]))

where NAME_OF_PROFILE_VIEW is the name of the callback that you are using. With django-profiles, NAME_OF_PROFILE_VIEW can be 'profiles_profile_detail'.

You need to add type assertion .(string). It is necessary because the map is of type map[string]interface{}:

host := arguments["<host>"].(string) + ":" + arguments["<port>"].(string)

Latest version of Docopt returns Opts object that has methods for conversion:

host, err := arguments.String("<host>")
port, err := arguments.String("<port>")
host_port := host + ":" + port

First way: JOIN:

get people with multiple countries:

SELECT u1.user_id 
FROM users u1
JOIN users u2
on u1.user_id  = u2.user_id 
AND u1.ancestry <> u2.ancestry

Get people from 2 specific countries:

SELECT u1.user_id 
FROM users u1
JOIN users u2
on u1.user_id  = u2.user_id 
WHERE u1.ancestry = 'Germany'
AND u2.ancestry = 'France'

For 3 countries... join three times. To only get the result(s) once, distinct.

Second way: GROUP BY

This will get users which have 3 lines (having...count) and then you specify which lines are permitted. Note that if you don't have a UNIQUE KEY on (user_id, ancestry), a user with 'id, england' that appears 3 times will also match... so it depends on your table structure and/or data.

SELECT user_id 
FROM users u1
WHERE ancestry = 'Germany'
OR ancestry = 'France'
OR ancestry = 'England'
GROUP BY user_id
HAVING count(DISTINCT ancestry) = 3

There are some misconceptions here.

Frequencies above 500 can be represented in an FFT result of length 1000. Unfortunately these frequencies are all folded together and mixed into the first 500 FFT result bins. So normally you don't want to feed an FFT a signal containing any frequencies at or above half the sampling rate, as the FFT won't care and will just mix the high frequencies together with the low ones (aliasing) making the result pretty much useless. That's why data should be low-pass filtered before being sampled and fed to an FFT.

The FFT returns amplitudes without frequencies because the frequencies depend, not just on the length of the FFT, but also on the sample rate of the data, which isn't part of the FFT itself or it's input. You can feed the same length FFT data at any sample rate, as thus get any range of frequencies out of it.

The reason the result plots ends at 500 is that, for any real data input, the frequencies above half the length of the FFT are just mirrored repeats (complex conjugated) of the data in the first half. Since they are duplicates, most people just ignore them. Why plot duplicates? The FFT calculates the other half of the result for people who feed the FFT complex data (with both real and imaginary components), which does create two different halves.

How about something like this.

function objectToArray( $object ){
   if( !is_object( $object ) && !is_array( $object ) ){
    return $object;
 }
if( is_object( $object ) ){
    $object = get_object_vars( $object );
}
    return array_map( 'objectToArray', $object );
}

and call this function with your object

$array = objectToArray( $yourObject );

reference

Yes, you can do that which returns boolean. The following java code in WebDriver with TestNG or JUnit can do:

protected boolean isTextPresent(String text){
    try{
        boolean b = driver.getPageSource().contains(text);
        return b;
    }
    catch(Exception e){
        return false;
    }
  }

Now call the above method as below:

assertTrue(isTextPresent("Your text"));

Or, there is another way. I think, this is the better way:

private StringBuffer verificationErrors = new StringBuffer();
try {
                  assertTrue(driver.findElement(By.cssSelector("BODY")).getText().matches("^[\\s\\S]*    Your text here\r\n\r\n[\\s\\S]*$"));
  } catch (Error e) {
     verificationErrors.append(e.toString());
   }

you can redirect the output to a file by using >> python with print rint's "chevron" syntax as indicated in the docs

let see,

fp=open('test.log','a')   # take file  object reference 
print >> fp , "hello world"            #use file object with in print statement.
print >> fp , "every thing will redirect to file "
fp.close()    #close the file 

checkout the file test.log you will have the data and to print on console just use plain print statement .

A possible idea would be to:

1. delete the width: 25%; float:left; from the style of your divs
2. wrap each of the four colored divs in a div that has style="width: 25%; float:left;"

The advantage with this approach is that all four columns will have equal width and the gap between them will always be 5px * 2.

Here's what it looks like:

.cellContainer {_x000D_
  width: 25%;_x000D_
  float: left;_x000D_
}

<div style="width:100%; height: 200px; background-color: grey;">_x000D_
  <div class="cellContainer">_x000D_
    <div style="margin: 5px; background-color: red;">A</div>_x000D_
  </div>_x000D_
  <div class="cellContainer">_x000D_
    <div style="margin: 5px; background-color: orange;">B</div>_x000D_
  </div>_x000D_
  <div class="cellContainer">_x000D_
    <div style="margin: 5px; background-color: green;">C</div>_x000D_
  </div>_x000D_
  <div class="cellContainer">_x000D_
    <div style="margin: 5px; background-color: blue;">D</div>_x000D_
  </div>_x000D_
</div>

I also had to remove the SMSS before it would get past that step.

Something that your code doesn't account for is displaying multiple errors. As you have noted above it is possible for the user to upload a file >2MB of the wrong type, but your code can only report one of the issues. Try something like:

if(isset($_FILES['uploaded_file'])) {
    $errors     = array();
    $maxsize    = 2097152;
    $acceptable = array(
        'application/pdf',
        'image/jpeg',
        'image/jpg',
        'image/gif',
        'image/png'
    );

    if(($_FILES['uploaded_file']['size'] >= $maxsize) || ($_FILES["uploaded_file"]["size"] == 0)) {
        $errors[] = 'File too large. File must be less than 2 megabytes.';
    }

    if((!in_array($_FILES['uploaded_file']['type'], $acceptable)) && (!empty($_FILES["uploaded_file"]["type"]))) {
        $errors[] = 'Invalid file type. Only PDF, JPG, GIF and PNG types are accepted.';
    }

    if(count($errors) === 0) {
        move_uploaded_file($_FILES['uploaded_file']['tmpname'], '/store/to/location.file');
    } else {
        foreach($errors as $error) {
            echo '<script>alert("'.$error.'");</script>';
        }

        die(); //Ensure no more processing is done
    }
}

Look into the docs for move_uploaded_file() (it's called move not store) for more.

The List interface already has this solved.

int temp = 2;
if(bankAccNos.contains(bakAccNo)) temp=1;

More can be found in the documentation about List.

On GNU-compatible systems (i.e. Linux):

find . -mtime 0 -printf '%T+\t%s\t%p\n' 2>/dev/null | sort -r | more

This will list files and directories that have been modified in the last 24 hours (-mtime 0). It will list them with the last modified time in a format that is both sortable and human-readable (%T+), followed by the file size (%s), followed by the full filename (%p), each separated by tabs (\t).

2>/dev/null throws away any stderr output, so that error messages don't muddy the waters; sort -r sorts the results by most recently modified first; and | more lists one page of results at a time.

In case anybody else falls onto this page, you can also solve this by using the Ip address in the URL request instead of the domain:

NSURL *myURL = [NSURL URLWithString:@"http://10.0.0.2/mypage.php"];

Then you specify the Host manually:

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:myURL];
[request setAllHTTPHeaderFields:[NSDictionary dictionaryWithObjectAndKeys:@"myserver",@"Host"]];

As far as the server is concerned, it will behave the exact same way as if you had used http://myserver/mypage.php, except that the iPhone will not have to do a DNS lookup.

This thread has plenty of answers stating that the BigDecimal.compareTo(BigDecimal) method is the one to use to compare BigDecimal instances. I just wanted to add for anymore not experienced with using the BigDecimal.compareTo(BigDecimal) method to be careful with how you are creating your BigDecimal instances. So, for example...

• new BigDecimal(0.8) will create a BigDecimal instance with a value which is not exactly 0.8 and which has a scale of 50+,
• new BigDecimal("0.8") will create a BigDecimal instance with a value which is exactly 0.8 and which has a scale of 1

... and the two will be deemed to be unequal according to the BigDecimal.compareTo(BigDecimal) method because their values are unequal when the scale is not limited to a few decimal places.

First of all, be careful to create your BigDecimal instances with the BigDecimal(String val) constructor or the BigDecimal.valueOf(double val) method rather than the BigDecimal(double val) constructor. Secondly, note that you can limit the scale of BigDecimal instances prior to comparing them by means of the BigDecimal.setScale(int newScale, RoundingMode roundingMode) method.

I'm not sure of the git command for it yet, but I think you can find them in the reflogs.

.git/logs/refs/heads/<yourbranch>

My files appear to have a unix timestamp in them.

Update: There appears to be an option to use the reflog history instead of the commit history when printing the logs:

git log -g

You can follow this log as well, back to when you created the branch. git log is showing the date of the commit, though, not the date when you made the action that made an entry in the reflog. I haven't found that yet except by looking in the actual reflog in the path above.

anArray[10][10] is not a pointer to a pointer, it is a contiguous chunk of memory suitable for storing 100 values of type double, which compiler knows how to address because you specified the dimensions. You need to pass it to a function as an array. You can omit the size of the initial dimension, as follows:

void f(double p[][10]) {
}

However, this will not let you pass arrays with the last dimension other than ten.

The best solution in C++ is to use std::vector<std::vector<double> >: it is nearly as efficient, and significantly more convenient.

Log.WriteLine("Value of CompanyName column:" + thisReader["CompanyName"]); 

Use the binascii module:

>>> import binascii
>>> binascii.hexlify('foo'.encode('utf8'))
b'666f6f'
>>> binascii.unhexlify(_).decode('utf8')
'foo'

See this answer: Python 3.1.1 string to hex

Strip out tags, leave only alphanumeric characters and space:

$clear = preg_replace('/[^a-zA-Z0-9\s]/', '', strip_tags($des));

Edit: all credit to DaveRandom for the perfect solution...

$clear = preg_replace('/[^a-zA-Z0-9\s]/', '', strip_tags(html_entity_decode($des)));

There're already answers for windows. In linux, I noticed open https://www.google.com always launch browser from shell, so you can try:

system("open https://your.domain/uri");

that's say

system(("open "s + url).c_str()); // c++

You can increase the List View Threshold beyond the 5,000 default, but it is highly recommended that you don't, as it has performance implications. The recommended fix is to add an index to the field or fields used in the query (usually the ID field for a list or the Title field for a library).

When there is an index, that is used to retrieve the item(s); when there is no index the whole list is opened for a scan (and therefore hits the threshold). You create the index on the List (or Library) settings page.

The tomcat manual says:

Copy the web application archive file into directory $CATALINA_HOME/webapps/. When Tomcat is started, it will automatically expand the web application archive file into its unpacked form, and execute the application that way.

Out[84]: 11

UPDATE: starting from Pandas 0.20.1 the .ix indexer is deprecated, in favor of the more strict .iloc and .loc indexers.

You're not using react native or react so forgive me this isn't a solution for you. - since this is a 7 year old post I'm pretty sure you figured it out by now ;)

But I was looking for something similar for react-native and it led me to this SO question. Incase anyone else winds up down the same road I thought I'd share my use-moment-countdown hook for react or react native: https://github.com/BrooklinJazz/use-moment-countdown.

For example you can make a 10 minute timer like so:

import React from 'react'

import  { useCountdown } from 'use-moment-countdown'

const App = () => {
  const {start, time} = useCountdown({m: 10})
  return (
    <div onClick={start}>
      {time.format("hh:mm:ss")}
    </div>
  )
}

export default App

You can enable pretty-printing by setting the SerializationFeature.INDENT_OUTPUT on your ObjectMapper like so:

mapper.enable(SerializationFeature.INDENT_OUTPUT);

Another tip that would help a lot is that to set the current directory to a different drive one would have to use %~d0 first, then cd %~dp0. This will change the directory to the batch file's drive, then change to its folder.

Alternatively, for #oneLinerLovers, as @Omni pointed out in the comments cd /d %~dp0 will change both the drive and directory :)

Hope this helps someone.

function convertByte()
{
    var c=document.getElementById("str").value;
    var arr = [];
    var i=0;
    for(var ind=0;ind<c.length;ind++)
    {
        arr[ind]=c.charCodeAt(i);
        i++;
    }    
    document.getElementById("result").innerHTML="The converted value is "+arr.join("");    
}

Your second approach doesn't work because {name: 'someothername'} equals {name: 'someothername', age: undefined}, so theundefined would overwrite original age value.

When it comes to change state in nested objects, a good approach would be Immutable.js

this.state = {
  jasper: Record({name: 'jasper', age: 28})
}

const {jasper} = this.state
this.setState({jasper: jasper.set(name, 'someothername')})

Use get_browser() function.

It can give you output like this:

Array
(
    [browser_name_regex] => ^mozilla/5\.0 (windows; .; windows nt 5\.1; .*rv:.*) gecko/.* firefox/0\.9.*$
    [browser_name_pattern] => Mozilla/5.0 (Windows; ?; Windows NT 5.1; *rv:*) Gecko/* Firefox/0.9*
    [parent] => Firefox 0.9
    [platform] => WinXP
    [browser] => Firefox
    [version] => 0.9
    [majorver] => 0
    [minorver] => 9
    .... 

It looks like that this limitation can be avoided if you use the following URL pattern:

https://googledrive.com/host/file-id

For your case the download URL will look like this - https://googledrive.com/host/0ByvXJAlpPqQPYWNqY0V3MGs0Ujg

Please keep in mind that this method works only if file is shared with "Public on the web" option.

The command line flags -N or --LINE-NUMBERS causes a line number to be displayed at the beginning of each line in the display.

You can also toggle line numbers without quitting less by typing -N<return>. It it possible to toggle any of less's command line options in this way.

CSS is not used to define values to DOM element attributes, javascript would be more suitable for this.

You can also use the shorter format

From the man page:

%F     full date; same as %Y-%m-%d

Example:

#!/bin/bash
date_today=$(date +%F)
date_dir=$(date +%F -d yesterday)

If you want to set a static row height, you can do something like this:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 120;
}

Add android:textAllCaps="false" in <Button> tag that's it.

If you need just one character and you don't want to keep things in the buffer, you can simply read a whole line and drop everything that isn't needed.

Replace:

stdin.read(1)

with

stdin.readline().strip()[:1]

This will read a line, remove spaces and newlines and just keep the first character.

This blog post discusses the best answers to this question.

As a short summary, if you can install CPAN modules then the most readable solutions are:

any(@ingredients) eq 'flour';

or

@ingredients->contains('flour');

However, a more common idiom is:

any { $_ eq 'flour' } @ingredients

But please don't use the first() function! It doesn't express the intent of your code at all. Don't use the ~~ "Smart match" operator: it is broken. And don't use grep() nor the solution with a hash: they iterate through the whole list.

any() will stop as soon as it finds your value.

Check out the blog post for more details.

I was just playing around with this same subject, which is the fastest way to access the pixels. I currently know of two ways for doing this:

1. Using BufferedImage's getRGB() method as described in @tskuzzy's answer.

2. By accessing the pixels array directly using:

   byte[] pixels = ((DataBufferByte) bufferedImage.getRaster().getDataBuffer()).getData();
   

If you are working with large images and performance is an issue, the first method is absolutely not the way to go. The getRGB() method combines the alpha, red, green and blue values into one int and then returns the result, which in most cases you'll do the reverse to get these values back.

The second method will return the red, green and blue values directly for each pixel, and if there is an alpha channel it will add the alpha value. Using this method is harder in terms of calculating indices, but is much faster than the first approach.

In my application I was able to reduce the time of processing the pixels by more than 90% by just switching from the first approach to the second!

Here is a comparison I've setup to compare the two approaches:

      else if (seconds == 0)
         return minutes + "min " + millisecs + "ms";
      else if (millisecs == 0)
         return minutes + "min " + seconds + "s";

      return minutes + "min " + seconds + "s " + millisecs + "ms";
   }
}

Can you guess the output? ;)

When you use the keyword new for example JFrame j = new JFrame(); you are creating an instance of the class JFrame.

The new operator instantiates a class by allocating memory for a new object and returning a reference to that memory.
Note: The phrase "instantiating a class" means the same thing as "creating an object." When you create an object, you are creating an "instance" of a class, therefore "instantiating" a class.

Take a look here
Creating Objects

The types of the Java programming language are divided into two categories: primitive types and reference types.
The reference types are class types, interface types, and array types.
There is also a special null type.
An object is a dynamically created instance of a class type or a dynamically created array.
The values of a reference type are references to objects.

Check this out: How to replace all occurrences of a string in JavaScript?

Short answer:

str.replace(/%20/g, " ");

EDIT: In this case you could also do the following:

decodeURI(str)

This is the solution I use. It has more lines but it will only create the datepicker once.

$('#txtSearch').datepicker({
    constrainInput:false,
    beforeShow: function(){
        var t = $('#ddlSearchType').val();
        if( ['Required Date', 'Submitted Date'].indexOf(t) ) {
            $('#txtSearch').prop('readonly', false);
            return false;
        }
        else $('#txtSearch').prop('readonly', true);
    }
});

The datepicker will not show unless the value of ddlSearchType is either "Required Date" or "Submitted Date"

You could as well take an alternative approach -- you don't have to use $http, you don't need any extra libraries, and it ought to work in any browser.

Just place an invisible form on your page.

<form name="downloadForm" action="/MyApp/MyFiles/Download" method="post" target="_self">
    <input type="hidden" name="value1" value="{{ctrl.value1}}" />
    <input type="hidden" name="value2" value="{{ctrl.value2}}" />
</form>

And place this code in your angular controller.

ctrl.value1 = 'some value 1';  
ctrl.value2 = 'some value 2';  
$timeout(function () {
    $window.document.forms['downloadForm'].submit();
});

This code will post your data to /MyApp/MyFiles/Download and you'll receive a file in your Downloads folder.
It works with Internet Explorer 10.

If a conventional HTML form doesn't let you post your complex object, then you have two options:

1. Stringify your object and put it into one of the form fields as a string.

<input type="hidden" name="myObjJson" value="{{ctrl.myObj | json:0}}" />

2. Consider HTML JSON forms: https://www.w3.org/TR/html-json-forms/

From their signature generator, you can generate curl commands of the form:

curl --get 'https://api.twitter.com/1.1/statuses/user_timeline.json' --data 'count=2&screen_name=twitterapi' --header 'Authorization: OAuth oauth_consumer_key="YOUR_KEY", oauth_nonce="YOUR_NONCE", oauth_signature="YOUR-SIG", oauth_signature_method="HMAC-SHA1", oauth_timestamp="TIMESTAMP", oauth_token="YOUR-TOKEN", oauth_version="1.0"' --verbose

if you directly get get max number by writing select query then there may chance that your query will give wrong value. e.g. if your table has 5 records so your increment id will be 6 and if I delete record no 5 the your table has 4 records with max id is 4 in this case you will get 5 as next increment id. insted to that you can get info from mysql defination itself. by writing following code in php

<?
$tablename      = "tablename";
$next_increment     = 0;
$qShowStatus        = "SHOW TABLE STATUS LIKE '$tablename'";
$qShowStatusResult  = mysql_query($qShowStatus) or die ( "Query failed: " . mysql_error() . "<br/>" . $qShowStatus );

$row = mysql_fetch_assoc($qShowStatusResult);
$next_increment = $row['Auto_increment'];

echo "next increment number: [$next_increment]";
?>

When I were trying install librosa package with pip (pip install librosa), this error were appeared:

ERROR: Cannot uninstall 'llvmlite'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

I tried to remove llvmlite, but pip uninstall could not remove it. So, I used capability of ignore of pip by this code:

pip install librosa --ignore-installed llvmlite

Indeed, you can use this rule for ignoring a package you don't want to consider:

pip install {package you want to install} --ignore-installed {installed package you don't want to consider}

InputStream is;
InputStreamReader r = new InputStreamReader(is);
BufferedReader br = new BufferedReader(r);

In response to Thomas Browne's comment, because lnmx's answer only works for subtracting a date, here is a modification of his code that works for subtracting time from a time.Time type.

package main

import (
    "fmt"
    "time"
)

func main() {
    now := time.Now()

    fmt.Println("now:", now)

    count := 10
    then := now.Add(time.Duration(-count) * time.Minute)
    // if we had fix number of units to subtract, we can use following line instead fo above 2 lines. It does type convertion automatically.
    // then := now.Add(-10 * time.Minute)
    fmt.Println("10 minutes ago:", then)
}

Produces:

now: 2009-11-10 23:00:00 +0000 UTC
10 minutes ago: 2009-11-10 22:50:00 +0000 UTC

Not to mention, you can also use time.Hour or time.Second instead of time.Minute as per your needs.

There's now a simpler way with .NET Standard or .NET Core:

var client = new HttpClient();
var response = await client.PostAsync(uri, myRequestObject, new JsonMediaTypeFormatter());

NOTE: In order to use the JsonMediaTypeFormatter class, you will need to install the Microsoft.AspNet.WebApi.Client NuGet package, which can be installed directly, or via another such as Microsoft.AspNetCore.App.

Using this signature of HttpClient.PostAsync, you can pass in any object and the JsonMediaTypeFormatter will automatically take care of serialization etc.

With the response, you can use HttpContent.ReadAsAsync<T> to deserialize the response content to the type that you are expecting:

var responseObject = await response.Content.ReadAsAsync<MyResponseType>();

If you just want to print the substrings ...

char s[] = "THESTRINGHASNOSPACES";
size_t i, slen = strlen(s);
for (i = 0; i < slen; i += 4) {
  printf("%.4s\n", s + i);
}

EDIT: the following is wrong, because Cell("width") returns the width of the last modified cell.

Cell("width") returns the width of the current cell, so you don't need a reference to the current cell. If you need one, though, cell("address") returns the address of the current cell, so if you need a reference to the current cell, use indirect(cell("address")). See the documentation: http://www.techonthenet.com/excel/formulas/cell.php

Two ways.

i. You can put it in ApplicationController and add the filters in the controller

    class ApplicationController < ActionController::Base       def filter_method       end     end      class FirstController < ApplicationController       before_filter :filter_method     end      class SecondController < ApplicationController       before_filter :filter_method     end 

But the problem here is that this method will be added to all the controllers since all of them extend from application controller

ii. Create a parent controller and define it there

 class ParentController < ApplicationController   def filter_method   end  end  class FirstController < ParentController   before_filter :filter_method end  class SecondController < ParentController   before_filter :filter_method end 

I have named it as parent controller but you can come up with a name that fits your situation properly.

You can also define the filter method in a module and include it in the controllers where you need the filter

column_obj != None will produce a IS NOT NULL constraint:

In a column context, produces the clause a != b. If the target is None, produces a IS NOT NULL.

or use isnot() (new in 0.7.9):

Implement the IS NOT operator.

Normally, IS NOT is generated automatically when comparing to a value of None, which resolves to NULL. However, explicit usage of IS NOT may be desirable if comparing to boolean values on certain platforms.

Demo:

>>> from sqlalchemy.sql import column
>>> column('YourColumn') != None
<sqlalchemy.sql.elements.BinaryExpression object at 0x10c8d8b90>
>>> str(column('YourColumn') != None)
'"YourColumn" IS NOT NULL'
>>> column('YourColumn').isnot(None)
<sqlalchemy.sql.elements.BinaryExpression object at 0x104603850>
>>> str(column('YourColumn').isnot(None))
'"YourColumn" IS NOT NULL'

fline=open("myfile").readline().rstrip()

For anyone going through this error and you've tried updating versions and making sure effects core is present etc and still scratching your head. Check the documentation for animate() and other syntax.

All I did was write "Linear" instead of "linear" and got the [this.easing] is not a function

$("#main").animate({ scrollLeft: '187px'}, 'slow', 'Linear'); //bad

$("#main").animate({ scrollLeft: '187px'}, 'slow', 'linear'); //good

You can do it (albeit not lightning-quickly) like so:

people.Where(p => !people.Any(q => (p != q && p.Id == q.Id)));

That is, "select all people where there isn't another different person in the list with the same ID."

Mind you, in your example, that would just select person 3. I'm not sure how to tell which you want, out of the previous two.

Basically this world's problems can be categorized as

         1) Unsolvable Problem          2) Intractable Problem          3) NP-Problem          4) P-Problem

         1)The first one is no solution to the problem.          2)The second is the need exponential time (that is O (2 ^ n) above).          3)The third is called the NP.          4)The fourth is easy problem.

P: refers to a solution of the problem of Polynomial Time.

NP: refers Polynomial Time yet to find a solution. We are not sure there is no Polynomial Time solution, but once you provide a solution, this solution can be verified in Polynomial Time.

NP Complete: refers in Polynomial Time we still yet to find a solution, but it can be verified in Polynomial Time . The problem NPC in NP is the more difficult problem, so if we can prove that we have P solution to NPC problem then NP problems that can be found in P solution.

NP Hard: refers Polynomial Time is yet to find a solution, but it sure is not able to be verified in Polynomial Time . NP Hard problem surpasses NPC difficulty.

easiest way ta make java leap year and more clear to understandenter code here

import  java.util.Scanner;

class que19{

public static void main(String[] args) {

    Scanner input=new Scanner(System.in);

    double a;

    System.out.println("enter the year here ");
    a=input.nextDouble();
    if ((a % 4 ==0 ) && (a%100!=0) || (a%400==0)) {
        System.out.println("leep year");

    }
    else {
        System.out.println("not a leap year");
    }
}

}

You can do it with a simple loop:

var obj = null;    
for (var i = 0; i < array.length; i++) {
    if (array[i].name == "string 1") {
        obj = array[i];
        break;
    }
}

You can use:

    select FK_Items,Sum(PoiQuantity) Quantity  from PurchaseOrderItems POI
    left join PurchaseOrder PO ON po.ID_PurchaseOrder=poi.FK_PurchaseOrder
    group by FK_Items,DATEPART(MONTH, TransDate)

I did which node on my terminal: /usr/local/bin/node

and then i added "runtimeExecutable": "/usr/local/bin/node" in my json file.

Swift

Updated for Swift 3

// current date and time
let someDate = Date()

// time interval since 1970
let myTimeStamp = someDate.timeIntervalSince1970

Notes

• timeIntervalSince1970 returns TimeInterval, which is a typealias for Double.

• If you wanted to go the other way you could do the following:

    let myDate = Date(timeIntervalSince1970: myTimeStamp)
  

Another interesting way to listen file input changes is with a watch over the ng-model attribute of the input file. Off course FileModel is a custom directive.

Like this:

HTML -> <input type="file" file-model="change.fnEvidence">

JS Code ->

$scope.$watch('change.fnEvidence', function() {
                    alert("has changed");
                });

Hope it can helps someone.

DELETE FROM table_name 
WHERE id BETWEEN 79 AND 296;

This actually works:

 getActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
 getActionBar().setCustomView(R.layout.custom_actionbar);
  ActionBar.LayoutParams p = new ActionBar.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        p.gravity = Gravity.CENTER;

You have to define custom_actionbar.xml layout which is as per your requirement e.g. :

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="50dp"
    android:background="#2e2e2e"
    android:orientation="vertical"
    android:gravity="center"
    android:layout_gravity="center">

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/top_banner"
        android:layout_gravity="center"
        />
</LinearLayout>

I'm not sure if you want to find duplicate files or just compare two single files. If the latter, the above approach (filecmp) is better, if the former, the following approach is better.

There are lots of duplicate files detection questions here. Assuming they are not very small and that performance is important, you can

• Compare file sizes first, discarding all which doesn't match
• If file sizes match, compare using the biggest hash you can handle, hashing chunks of files to avoid reading the whole big file

Here's is an answer with Python implementations (I prefer the one by nosklo, BTW)

Why is this answer still getting upvotes?

Per Mikaël Mayer's answer, this is no longer a problem, and my answer is obsolete (go() now returns 30 after mucking with the console). This was fixed in July 2013, according to the bug report linked above in gabrielmaldi's comment. It alarms me that I'm still getting upvotes - makes me think the upvoter doesn't understand either the question or my answer.

I'll leave my original answer here for historical reasons, but go upvote Mikaël's answer instead.

The trick is that you can't change a local variable directly, but you can modify the properties of an object. You can also modify the value of a global variable:

var g_n = 0;
function go()
{
    var n = 0;
    var o = { n: 0 };
    return g_n + n + o.n;  // breakpoint here
}

console:

> g_n = 10
  10
> g_n
  10
> n = 10
  10
> n
  0
> o.n = 10
  10
> o.n
  10

Check the result of go() after setting the breakpoint and running those calls in the console, and you'll find that the result is 20, rather than 0 (but sadly, not 30).

If you're on a mac, by far the simplest way to install is to use easy_install

sudo easy_install boto3

Fetch promises only reject with a TypeError when a network error occurs. Since 4xx and 5xx responses aren't network errors, there's nothing to catch. You'll need to throw an error yourself to use Promise#catch.

A fetch Response conveniently supplies an ok , which tells you whether the request succeeded. Something like this should do the trick:

fetch(url).then((response) => {
  if (response.ok) {
    return response.json();
  } else {
    throw new Error('Something went wrong');
  }
})
.then((responseJson) => {
  // Do something with the response
})
.catch((error) => {
  console.log(error)
});

JSON does not know anything about dates. What .NET does is a non-standard hack/extension.

I would use a format that can be easily converted to a Date object in JavaScript, i.e. one that can be passed to new Date(...). The easiest and probably most portable format is the timestamp containing milliseconds since 1970.

The following code works more or less as one would expect a type-switch that only looks at the actual type (e.g. what is returned by GetType()).

public static void TestTypeSwitch()
{
    var ts = new TypeSwitch()
        .Case((int x) => Console.WriteLine("int"))
        .Case((bool x) => Console.WriteLine("bool"))
        .Case((string x) => Console.WriteLine("string"));

    ts.Switch(42);     
    ts.Switch(false);  
    ts.Switch("hello"); 
}

Here is the machinery required to make it work.

public class TypeSwitch
{
    Dictionary<Type, Action<object>> matches = new Dictionary<Type, Action<object>>();
    public TypeSwitch Case<T>(Action<T> action) { matches.Add(typeof(T), (x) => action((T)x)); return this; } 
    public void Switch(object x) { matches[x.GetType()](x); }
}

Change file permission to 755 for the file:

lots of correct answers, but as I landed here to copy & paste a folder rename with history, I found that this

git mv <old name> <new name>

will move the old folder (itself) to nest within the new folder

while

git mv <old name>/ <new name>

(note the '/') will move the nested content from the old folder to the new folder

both commands didn't copy along the history of nested files. I eventually renamed each nested folder individually ?

git mv <old name>/<nest-folder> <new name>/<nest-folder>
