I am not familiar with JXL and but we use POI. POI is well maintained and can handle both the binary .xls format and the new xml based format that was introduced in Office 2007.

CSV files are not excel files, they are text based files, so these libraries don't read them. You will need to parse out a CSV file yourself. I am not aware of any CSV file libraries, but I haven't looked either.

Better to overwrite the whole line otherwise the new line will mix with the old ones if the new line is shorter.

import time, os
for s in ['overwrite!', 'the!', 'whole!', 'line!']:
    print(s.ljust(os.get_terminal_size().columns - 1), end="\r")
    time.sleep(1)

Had to use columns - 1 on Windows.

4gb RAM doesn't mean you can use it all for java process. Lots of RAM is needed for system processes. Dont go above 2GB or it will be trouble some.

Before starting jvm just check how much RAM is available and then set memory accordingly.

Create an S3 client object with your credentials

AWS_S3_CREDS = {
    "aws_access_key_id":"your access key", # os.getenv("AWS_ACCESS_KEY")
    "aws_secret_access_key":"your aws secret key" # os.getenv("AWS_SECRET_KEY")
}
s3_client = boto3.client('s3',**AWS_S3_CREDS)

It is always good to get credentials from os environment

To set Environment variables run the following commands in terminal

if linux or mac

$ export AWS_ACCESS_KEY="aws_access_key"
$ export AWS_SECRET_KEY="aws_secret_key"

if windows

c:System\> set AWS_ACCESS_KEY="aws_access_key"
c:System\> set AWS_SECRET_KEY="aws_secret_key"

So essentially you have a list of lists, with mylist being the name of the main list and the first element being $f10010_1 which is printed out (and which contains 4 more lists).

I think the easiest way to do this is to use lapply with the addition of dataframe (assuming that each list inside each element of the main list (like the lists in $f10010_1) has the same length):

lapply(mylist, function(x) write.table( data.frame(x), 'test.csv'  , append= T, sep=',' ))

The above will convert $f10010_1 into a dataframe then do the same with every other element and append one below the other in 'test.csv'

You can also type ?write.table on your console to check what other arguments you need to pass when you write the table to a csv file e.g. whether you need row names or column names etc.

This can as well be triggered by having both input and label inside the element with click listener.

You click on the label, which triggers a click event and as well another click event on the input for the label. Both events bubble to your element.

See this pen of a fancy CSS-only toggle: https://codepen.io/stepanh/pen/WaYzzO

Note: This is not jQuery specific, native listener is triggered 2x as well as shown in the pen.

You'll be wanting to use the 'read' command

while read name
do
    echo "$name"
done < names.txt

Note that "$name" is quoted -- if it's not, it will be split using the characters in $IFS as delimiters. This probably won't be noticed if you're just echoing the variable, but if your file contains a list of file names which you want to copy, those will get broken down by $IFS if the variable is unquoted, which is not what you want or expect.

If you want to use Mike Clark's approach (loading into a variable rather than using read), you can do it without the use of cat:

NAMES="$(< scripts/names.txt)" #names from names.txt file
for NAME in $NAMES; do
    echo "$NAME"
done

The problem with this is that it loads the whole file into $NAMES, when you read it back out, you can either get the whole file (if quoted) or the file broken down by $IFS, if not quoted. By default, this will give you individual words, not individual lines. So if the name "Mary Jane" appeared on a line, you would get "Mary" and "Jane" as two separate names. Using read will get around this... although you could also change the value of $IFS

I would like to recommend using the scrollTo plugin

http://demos.flesler.com/jquery/scrollTo/

You can the set scrollto by jquery css selector.

$('html,body').scrollTo( $(target), 800 );

I have had great luck with the accuracy of this plugin and its methods, where other methods of achieving the same effect like using .offset() or .position() have failed to be cross browser for me in the past. Not saying you can't use such methods, I'm sure there is a way to do it cross browser, I've just found scrollTo to be more reliable.

I think the possibilities are less, but FireBug (addon of FireFox) has some network analysis tools, too.

    buildToolsVersion "19.0.3"

    }

    File signFile = rootProject.file('sign/keystore.properties')
    if (signFile.exists()) {
        Properties properties = new Properties()
        properties.load(new FileInputStream(signFile))
        signingConfigs {
            release {
                storeFile rootProject.file(properties['keystore'])

There's no primitive for this in C. I'd probably malloc (or perhaps alloca) a long enough buffer and loop over the input. I've also seen it done with a dynamic string library with semantics (but not syntax!) similar to C++'s ostringstream, which is a plausibly more generic solution but it may not be worth the extra complexity just for a single case.

If you just use rm, you will need to follow it up with git add <fileRemoved>. git rm does this in one step.

You can also use git rm --cached which will remove the file from the index (staging it for deletion on the next commit), but keep your copy in the local file system.

Thank you for the solution. In my case the file %appdata%\pip\pip.ini was not present. I created it manually with this content:

[global]
trusted-host = pypi.python.org files.pythonhosted.org pypi.org pypi.io

In our case we experienced this while performing a load test on our app server. The issue turned out that we need to add additional memory to our JVM because it was running out. This resolved the issue.

Try increasing the memory available to the JVM and or monitor the memory usage when you get those errors.

Open libraries/Input.php (system/core/Input.php in CI version 2.0+) and locate function _clean_input_keys($str){,

Modify if ( ! preg_match("/^[a-z0-9:_\/-]+$/i", $str)) to if ( ! preg_match("/^[a-z0-9:_\-|]+$/i", $str))

Have you installed it using sudo? Was the error in my case.

$("**:**input[type=text], :input[type='textarea']").css({width: '90%'});

You can use something like this :

Try this code

$('#frmStudent').on('submit', function() {
  $(#StudentModal).on('hide.bs.modal', function (e) {

});

Simple, without any other API:

To add 8 days:

Date today=new Date();
long ltime=today.getTime()+8*24*60*60*1000;
Date today8=new Date(ltime);

I was having a similar issue. In my case, looking at the CSS i found a position: initial.

After some research, i found that mobile IE browser doesn't supports it.

I simply put a position: relative instead and everything worked fine.

I had to remove the following files too since brew complained in install later after manually removing all files.

/usr/local/share/doc/node/gdbinit

/usr/local/share/systemtap/tapset/node.stp

and then do the following

brew install node 

brew link node

As an alternative, in ES6, spread syntax might be used. ${Object.keys(alerts).length + 1} returns next id for alert.

let alerts = { _x000D_
    1: {app:'helloworld',message:'message'},_x000D_
    2: {app:'helloagain',message:'another message'}_x000D_
};_x000D_
_x000D_
alerts = {_x000D_
  ...alerts, _x000D_
  [`${Object.keys(alerts).length + 1}`]: _x000D_
  { _x000D_
    app: `helloagain${Object.keys(alerts).length + 1}`,message: 'next message' _x000D_
  } _x000D_
};_x000D_
_x000D_
console.log(alerts);

In fact, it's normal that you have a 404 error when refreshing your application since the actual address within the browser is updating (and without # / hashbang approach). By default, HTML5 history is used for reusing in Angular2.

To fix the 404 error, you need to update your server to serve the index.html file for each route path you defined.

If you want to switch to the HashBang approach, you need to use this configuration:

import {bootstrap} from 'angular2/platform/browser';
import {provide} from 'angular2/core';
import {ROUTER_PROVIDERS} from 'angular2/router';
import {LocationStrategy, HashLocationStrategy} from '@angular/common';

import {MyApp} from './myapp';

bootstrap(MyApp, [
  ROUTER_PROVIDERS,
  {provide: LocationStrategy, useClass: HashLocationStrategy}
]);

In this case, when you refresh the page, it will be displayed again (but you will have a # in your address).

This link could help you as well: When I refresh my website I get a 404. This is with Angular2 and firebase.

Hope it helps you, Thierry

Came here looking for an answer to the same problem, but I'm using WCF for NET Core. If you're in the same boat, use:

client.ClientCredentials.ServiceCertificate.SslCertificateAuthentication = 
    new X509ServiceCertificateAuthentication()
    {
        CertificateValidationMode = X509CertificateValidationMode.None,
        RevocationMode = X509RevocationMode.NoCheck
    };

imwrite(A,filename) writes image data A to the file specified by filename, inferring the file format from the extension

I have a function which returns a CLOB and I was seeing the above error when I'd forgotten to declare the return value as an output parameter. Initially I had:

protected SimpleJdbcCall buildJdbcCall(JdbcTemplate jdbcTemplate)
{
    SimpleJdbcCall call = new SimpleJdbcCall(jdbcTemplate)
        .withSchemaName(schema)
        .withCatalogName(catalog)
        .withFunctionName(functionName)
        .withReturnValue()          
        .declareParameters(buildSqlParameters());

    return call;
}

public SqlParameter[] buildSqlParameters() {
    return new SqlParameter[]{
        new SqlParameter("p_names", Types.VARCHAR),
        new SqlParameter("p_format", Types.VARCHAR),
        new SqlParameter("p_units", Types.VARCHAR),
        new SqlParameter("p_datums", Types.VARCHAR),
        new SqlParameter("p_start", Types.VARCHAR),
        new SqlParameter("p_end", Types.VARCHAR),
        new SqlParameter("p_timezone", Types.VARCHAR),
        new SqlParameter("p_office_id", Types.VARCHAR),
        };
}

The buildSqlParameters method should have included the SqlOutParameter:

public SqlParameter[] buildSqlParameters() {
    return new SqlParameter[]{
        new SqlParameter("p_names", Types.VARCHAR),
        new SqlParameter("p_format", Types.VARCHAR),
        new SqlParameter("p_units", Types.VARCHAR),
        new SqlParameter("p_datums", Types.VARCHAR),
        new SqlParameter("p_start", Types.VARCHAR),
        new SqlParameter("p_end", Types.VARCHAR),
        new SqlParameter("p_timezone", Types.VARCHAR),
        new SqlParameter("p_office_id", Types.VARCHAR),
        new SqlOutParameter("l_clob", Types.CLOB)  // <-- This was missing!
    }; 
}

If you have queries to a DBMS for which the locality is quite restricted (say, a user only fires selects with a 'where username = $my_username') it makes sense to put all the usernames starting with A-M on one server and all from N-Z on the other. By this you get near linear scaling for some queries.

Long story short: Sharding is basically the process of distributing tables onto different servers in order to balance the load onto both equally.

Of course, it's so much more complicated in reality. :)

For JDK 8u102 things have changed, this worked for me:

1. Download windows JDK exe
2. Open with 7-Zip
3. Dump contents into a directory %JDK-EXE%
4. cmd: cd %JDK-EXE%.rsrc\1033\JAVA_CAB10
5. cmd: extrac32 111
6. Now have a tools.zip in directory, open it in 7-Zip
7. Extract contents into a new directory %JDK-VERSION%
8. cmd: cd %JDK-VERSION%
9. cmd: for /r %x in (*.pack) do .\bin\unpack200 -r "%x" "%~dx%~px%~nx.jar"
10. src.zip is in %JDK-EXE%.rsrc\1033\JAVA_CAB9\110\ - put a copy into %JDK-VERSION%

Now you are ready to go. You might want to setup JAVA_HOME and PATH to point to your %JDK-VERSION% dir and its BIN subdir.

Oracle VirtualBox allows users to install Mac OS X in a virtual machine. If you are comfortable with it, you could just use that way to use Xcode. This is legal if you "dual boot" your mac into windows, then install the VirtualBox within windows (or linux).

Other possibilities are cross-compilers such as Appcelerator Titanium (HTML, CSS and JavaScript) or MonoTouch (.NET).

Slight tweak to answer from @divbyzero above to fix sonar security warnings

CloseableHttpClient getInsecureHttpClient() throws GeneralSecurityException {
            TrustStrategy trustStrategy = (chain, authType) -> true;

            HostnameVerifier hostnameVerifier = (hostname, session) -> hostname.equalsIgnoreCase(session.getPeerHost());

            return HttpClients.custom()
                    .setSSLSocketFactory(new SSLConnectionSocketFactory(new SSLContextBuilder().loadTrustMaterial(trustStrategy).build(), hostnameVerifier))
                    .build();
        }

If you want to pass in the value to use, you have to use the enum type you declared and directly use the supplied value:

public string CreateFile(string id, string name, string description,
              /* --> */  SupportedPermissions supportedPermissions)
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = supportedPermissions // <---
    };

    return file.Id;
}

If you instead want to use a fixed value, you don't need any parameter at all. Instead, directly use the enum value. The syntax is similar to a static member of a class:

public string CreateFile(string id, string name, string description) // <---
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = SupportedPermissions.basic // <---
    };

    return file.Id;
}

Released in June 2012, Eclipse for Mobile Developers is an awesome starting point for developers looking to focus on Android development. I've used it for several projects since August and haven't been disappointed.

The os.path... approach was the 'done thing' in Python 2.

In Python 3, you can find directory of script as follows:

from pathlib import Path
cwd = Path(__file__).parents[0]

There may be situations when df.reset_index() cannot be used (e.g., when you need the index, too). In this case, use index.get_level_values() to access index values directly:

df['Trial'] = df.index.get_level_values(0)
df['measurement'] = df.index.get_level_values(1)

This will assign index values to individual columns and keep the index.

See the docs for further info.

Set data to this:

data ={"eventType":"AAS_PORTAL_START","data":{"uid":"hfe3hf45huf33545","aid":"1","vid":"1"}}

I agree that Pascal's solution is the way to go, but for those saying that it adds an extra task to remove the comments, you can use the following comment style trick to simplify your life:

<?php /* ?>
<tr>
      <td><?php echo $entry_keyword; ?></td>
      <td><input type="text" name="keyword" value="<?php echo $keyword; ?>" /></td>
    </tr>
    <tr>
      <td><?php echo $entry_sort_order; ?></td>
      <td><input name="sort_order" value="<?php echo $sort_order; ?>" size="1" /></td>
    </tr>
<?php // */ ?>

In order to stop the code block being commented out, simply change the opening comment to:

<?php //* ?>

I think the poster meant to say You do not have to allocate everything on theheap rather than the the stack.

Basically objects are allocated on the stack (if the object size allows, of course) because of the cheap cost of stack-allocation, rather than heap-based allocation which involves quite some work by the allocator, and adds verbosity because then you have to manage data allocated on the heap.

Well, if you study the structure of how the application life-cycle works,here , then you'll come to know that onPause() is called when another activity gains focus, and onStop() is called when the activity is no longer visible.

From what I have learned yet, you can call finish() only from the activity which is active and/or has the focus. If you're calling finish() from the onPause() method that means you're calling it when the activity is no longer active. thus an exception is thrown.

When you're calling finish() from onStop() then the activity is being sent to background, thus will no longer be visible, then this exception.

When you press the back button, onStop() is called.

Most probably, Android will automatically do for you what you are currently wanting to do.

1. Uninstall all JDKs installed on your computer from the Java Control Panel
2. Search for C:\ProgramData\Oracle\Java and delete that directory and all files contained within. You can do this from the command line using rmdir /S C:\ProgramData\Oracle\Java
3. Then search for C:\ProgramData\Oracle and delete the oracle folder. You can do this using rmdir /S C:\ProgramData\Oracle

4. Now install JDK and set the path.

5. Run the program.You won't find the same problem anymore.

        testKeyset.put(2, "second");
        testKeyset.put(3, "third");
        testKeyset.put(4, "fourth");

        // Print a single value relevant to a specified Key. (uses keySet())
        for(int mapKey: testKeyset.keySet())
            System.out.println(testKeyset.get(mapKey));

        // Print all values regardless of the key.
        for(String mapVal: testKeyset.values())
            System.out.println(mapVal.trim());

        // Displays the Map in Key-Value pairs (e.g: [1=first, 2=second, 3=third, 4=fourth])
        System.out.println(testKeyset.entrySet());

function Default(variable, new_value)
{
    if(new_value === undefined) { return (variable === undefined) ? null : variable; }
    return (variable === undefined) ? new_value : variable;
}

var a = 2, b = "hello", c = true, d;

var test = Default(a, 0),
test2 = Default(b, "Hi"),
test3 = Default(c, false),
test4 = Default(d, "Hello world");

window.alert(test + "\n" + test2 + "\n" + test3 + "\n" + test4);

If you don't want to use a List, ArrayList, or other dynamically-sized collection and then convert to an array (that's the method I'd recommend, by the way), then you'll have to allocate the array to its maximum possible size, keep track of how many items you put in it, and then create a new array with just those items in it:

private Update BuildMetaData(MetaData[] nvPairs)
{
    Update update = new Update();
    InputProperty[] ip = new InputProperty[20];  // how to make this "dynamic"
    int i;
    for (i = 0; i < nvPairs.Length; i++)
    {
        if (nvPairs[i] == null) break;
        ip[i] = new InputProperty(); 
        ip[i].Name = "udf:" + nvPairs[i].Name;
        ip[i].Val = nvPairs[i].Value;
    }
    if (i < nvPairs.Length)
    {
        // Create new, smaller, array to hold the items we processed.
        update.Items = new InputProperty[i];
        Array.Copy(ip, update.Items, i);
    }
    else
    {
        update.Items = ip;
    }
    return update;
}

An alternate method would be to always assign update.Items = ip; and then resize if necessary:

update.Items = ip;
if (i < nvPairs.Length)
{
    Array.Resize(update.Items, i);
}

It's less code, but will likely end up doing the same amount of work (i.e. creating a new array and copying the old items).

import cv2 as cv

im_color = cv.imread("lena.png", cv.IMREAD_COLOR)
im_gray = cv.cvtColor(im_color, cv.COLOR_BGR2GRAY)

At this point you have a color and a gray image. We are dealing with 8-bit, uint8 images here. That means the images can have pixel values in the range of [0, 255] and the values have to be integers.

Let's do a binary thresholding operation. It creates a black and white masked image. The black regions have value 0 and the white regions 255

_, mask = cv.threshold(im_gray, thresh=180, maxval=255, type=cv.THRESH_BINARY)
im_thresh_gray = cv.bitwise_and(im_gray, mask)

The mask can be seen below on the left. The image on it's right is the result of applying bitwise_and operation between the gray image and the mask. What happened is, the spatial locations where the mask had a pixel value zero (black), became pixel value zero in the result image. The locations where the mask had pixel value 255 (white), the resulting image retained it's original gray value.

To apply this mask to our original color image, we need to convert the mask into a 3 channel image as the original color image is a 3 channel image.

mask3 = cv.cvtColor(mask, cv.COLOR_GRAY2BGR)  # 3 channel mask

Then, we can apply this 3 channel mask to our color image using the same bitwise_and function.

im_thresh_color = cv.bitwise_and(im_color, mask3)

mask3 from the code is the image below on the left, and im_thresh_color is on its right.

You can plot the results and see for yourself.

cv.imshow("original image", im_color)
cv.imshow("binary mask", mask)
cv.imshow("3 channel mask", mask3)
cv.imshow("im_thresh_gray", im_thresh_gray)
cv.imshow("im_thresh_color", im_thresh_color)
cv.waitKey(0)

The original image is lenacolor.png that I found here.

if it is not the first two chars and you wanna remove F0 from the whole string then you gotta use this regex

   let string = 'F0123F0456F0';_x000D_
   let result = string.replace(/F0/ig, '');_x000D_
   console.log(result);

I use someting like that: (Xamarin and C# code)

  LinearLayout linLayout= new LinearLayout(this); 
    linLayout.SetGravity(GravityFlags.Center);

    TextView txtView= new TextView(this);  
     linLayout.AddView(txtView); 

the SetGravity puts my textView in the center of the layout. So SetGravity layout property refer to layout content

I discovered that the accepted answer actually doesn't always work, because \\Z may occur in the file. Another problem is that if you don't have the correct charset a whole bunch of unexpected things may happen which may cause the scanner to read only a part of the file.

The solution is to use a delimiter which you are certain will never occur in the file. However, this is theoretically impossible. What we CAN do, is use a delimiter that has such a small chance to occur in the file that it is negligible: such a delimiter is a UUID, which is natively supported in Java.

String content = new Scanner(file, "UTF-8")
    .useDelimiter(UUID.randomUUID().toString()).next();

You can call a stored procedure from another stored procedure by using the EXECUTE command.

Say your procedure is X. Then in X you can use

EXECUTE PROCEDURE Y () RETURNING_VALUES RESULT;"

The difference between

import java.util.*;

and

import java.util.*;
import java.util.List;
import java.util.Arrays;

becomes apparent when the code refers to some other List or Arrays (for example, in the same package, or also imported generally). In the first case, the compiler will assume that the Arrays declared in the same package is the one to use, in the latter, since it is declared specifically, the more specific java.util.Arrays will be used.

I found this answer works for me

<style type="text/css">
#background{

also add id="background" to the div for your content section

If you want to change your default shell to bash for all projects on Jenkins, you can do so in the Jenkins config through the web portal:

Manage Jenkins > Configure System (Skip this clicking if you want by just going to https://{YOUR_JENKINS_URL}/configure.)

Fill in the field marked 'Shell executable' with the value /bin/bash and click 'Save'.

None of the provided examples here work for the generic case, which are N dimensional matrices. Anything using "rows" assumes theres columns and rows only, a 4 dimensional matrix might have more.

Here is some example code copying a non-continuous N-dimensional matrix into a continuous memory stream - then converts it back into a Cv::Mat

#include <iostream>
#include <cstdint>
#include <cstring>
#include <opencv2/opencv.hpp>

int main(int argc, char**argv)
{
    if ( argc != 2 )
    {
        std::cerr << "Usage: " << argv[0] << " <Image_Path>\n";
        return -1;
    }
    cv::Mat origSource = cv::imread(argv[1],1);

    if (!origSource.data) {
        std::cerr << "Can't read image";
        return -1;
    }

    // this will select a subsection of the original source image - WITHOUT copying the data
    // (the header will point to a region of interest, adjusting data pointers and row step sizes)
    cv::Mat sourceMat = origSource(cv::Range(origSource.size[0]/4,(3*origSource.size[0])/4),cv::Range(origSource.size[1]/4,(3*origSource.size[1])/4));

    // correctly copy the contents of an N dimensional cv::Mat
    // works just as fast as copying a 2D mat, but has much more difficult to read code :)
    // see http://stackoverflow.com/questions/18882242/how-do-i-get-the-size-of-a-multi-dimensional-cvmat-mat-or-matnd
    // copy this code in your own cvMat_To_Char_Array() function which really OpenCV should provide somehow...
    // keep in mind that even Mat::clone() aligns each row at a 4 byte boundary, so uneven sized images always have stepgaps
    size_t totalsize = sourceMat.step[sourceMat.dims-1];
    const size_t rowsize = sourceMat.step[sourceMat.dims-1] * sourceMat.size[sourceMat.dims-1];
    size_t coordinates[sourceMat.dims-1] = {0};
    std::cout << "Image dimensions: ";
    for (int t=0;t<sourceMat.dims;t++)
    {
        // calculate total size of multi dimensional matrix by multiplying dimensions
        totalsize*=sourceMat.size[t];
        std::cout << (t>0?" X ":"") << sourceMat.size[t];
    }
    // Allocate destination image buffer
    uint8_t * imagebuffer = new uint8_t[totalsize];
    size_t srcptr=0,dptr=0;
    std::cout << std::endl;
    std::cout << "One pixel in image has " << sourceMat.step[sourceMat.dims-1] << " bytes" <<std::endl;
    std::cout << "Copying data in blocks of " << rowsize << " bytes" << std::endl ;
    std::cout << "Total size is " << totalsize << " bytes" << std::endl;
    while (dptr<totalsize) {
        // we copy entire rows at once, so lowest iterator is always [dims-2]
        // this is legal since OpenCV does not use 1 dimensional matrices internally (a 1D matrix is a 2d matrix with only 1 row)
        std::memcpy(&imagebuffer[dptr],&(((uint8_t*)sourceMat.data)[srcptr]),rowsize);
        // destination matrix has no gaps so rows follow each other directly
        dptr += rowsize;
        // src matrix can have gaps so we need to calculate the address of the start of the next row the hard way
        // see *brief* text in opencv2/core/mat.hpp for address calculation
        coordinates[sourceMat.dims-2]++;
        srcptr = 0;
        for (int t=sourceMat.dims-2;t>=0;t--) {
            if (coordinates[t]>=sourceMat.size[t]) {
                if (t==0) break;
                coordinates[t]=0;
                coordinates[t-1]++;
            }
            srcptr += sourceMat.step[t]*coordinates[t];
        }
   }

   // this constructor assumes that imagebuffer is gap-less (if not, a complete array of step sizes must be given, too)
   cv::Mat destination=cv::Mat(sourceMat.dims, sourceMat.size, sourceMat.type(), (void*)imagebuffer);

   // and just to proof that sourceImage points to the same memory as origSource, we strike it through
   cv::line(sourceMat,cv::Point(0,0),cv::Point(sourceMat.size[1],sourceMat.size[0]),CV_RGB(255,0,0),3);

   cv::imshow("original image",origSource);
   cv::imshow("partial image",sourceMat);
   cv::imshow("copied image",destination);

In order to use Qt with dynamic linking you have to specify the lib files (usually qtmaind.lib, QtCored4.lib and QtGuid4.lib for the "Debug" configration) in
Properties » Linker » Input » Additional Dependencies.

You also have to specify the path where the libs are, namely in
Properties » Linker » General » Additional Library Directories.

And you need to make the corresponding .dlls are accessible at runtime, by either storing them in the same folder as your .exe or in a folder that is on your path.

I got here googling for C# compiler error CS0176, through (duplicate) question Static member instance reference issue.

In my case, the error happened because I had a static method and an extension method with the same name. For that, see Static method and extension method with same name.

[May be this should have been a comment. Sorry that I don't have enough reputation yet.]

For me the problem was that I was running the migrate command not from inside the container where php was running. The extension was properly set there but not at my host machine.

Why not just using

<div [ngClass]="classes"> </div>

I am not sure what math can be done on a DATETIME data type, but if you are using PHP, I strongly recommend using the integer-based timestamps. Basically, you can store a 4-byte integer in the database using PHP's time() function. This makes doing math on it much more straightforward.

collection.findOne({
    username: /peter/i
}, function (err, user) {
    assert(/peter/i.test(user.username))
})

For some reason the above accepted answer does not work in New versions of Angular (V6).

for that use this..

async delay(ms: number) {
    await new Promise(resolve => setTimeout(()=>resolve(), ms)).then(()=>console.log("fired"));
}

above worked for me.

Usage:

this.delay(3000);

OR more accurate way

this.delay(3000).then(any=>{
     //your task after delay.
});

You can't return arrays from functions in C. You also can't (shouldn't) do this:

char *returnArray(char array []){
 char returned [10];
 //methods to pull values from array, interpret them, and then create new array
 return &(returned[0]); //is this correct?
} 

returned is created with automatic storage duration and references to it will become invalid once it leaves its declaring scope, i.e., when the function returns.

You will need to dynamically allocate the memory inside of the function or fill a preallocated buffer provided by the caller.

Option 1:

dynamically allocate the memory inside of the function (caller responsible for deallocating ret)

char *foo(int count) {
    char *ret = malloc(count);
    if(!ret)
        return NULL;

    for(int i = 0; i < count; ++i) 
        ret[i] = i;

    return ret;
}

Call it like so:

int main() {
    char *p = foo(10);
    if(p) {
        // do stuff with p
        free(p);
    }

    return 0;
}

Option 2:

fill a preallocated buffer provided by the caller (caller allocates buf and passes to the function)

void foo(char *buf, int count) {
    for(int i = 0; i < count; ++i)
        buf[i] = i;
}

And call it like so:

int main() {
    char arr[10] = {0};
    foo(arr, 10);
    // No need to deallocate because we allocated 
    // arr with automatic storage duration.
    // If we had dynamically allocated it
    // (i.e. malloc or some variant) then we 
    // would need to call free(arr)
}

Hello you need to open the index.php from the wamp server and change $suppress_localhost = false; from $suppress_localhost = true; then your wamp will working fine

See demo at http://jsbin.com/ApuJOSA/1/edit?html,output .

  function mousePositionOnCanvas(e) {
      var el=e.target, c=el;
      var scaleX = c.width/c.offsetWidth || 1;
      var scaleY = c.height/c.offsetHeight || 1;

      if (!isNaN(e.offsetX)) 
          return { x:e.offsetX*scaleX, y:e.offsetY*scaleY };

      var x=e.pageX, y=e.pageY;
      do {
        x -= el.offsetLeft;
        y -= el.offsetTop;
        el = el.offsetParent;
      } while (el);
      return { x: x*scaleX, y: y*scaleY };
  }

Please see @jlareau answer here: https://stackoverflow.com/questions/11534710/angularjs-how-to-use-routeparams-in-generating-the-templateurl

You can use a function to generate the template string:

var app = angular.module('app',[]);

app.config(
    function($routeProvider) {
        $routeProvider.
            when('/', {templateUrl:'/home'}).
            when('/users/:user_id', 
                {   
                    controller:UserView, 
                    templateUrl: function(params){ return '/users/view/' + params.user_id;   }
                }
            ).
            otherwise({redirectTo:'/'});
    }
);

For shorter JavaScript-Code use this:

myApp.service('userService', [
  '$q', function($q) {
    this.initialized = $q.when();
    this.user = {
      access: false
    };
    this.isAuthenticated = function() {
      this.user = {
        first_name: 'First',
        last_name: 'Last',
        email: '[email protected]',
        access: 'institution'
      };
      return this.initialized;
    };
  }
]);

You know that you loose the binding to userService.user by overwriting it with a new object instead of setting only the objects properties?

Here is what I mean as a example of my plnkr.co example code (Working example: http://plnkr.co/edit/zXVcmRKT1TmiBCDL4GsC?p=preview):

angular.module('myApp', []).service('userService', [
    '$http', '$q', '$rootScope', '$location', function ($http, $q, $rootScope, $location) {
    this.initialized = $q.when(null);
    this.user = {
        access: false
    };
    this.isAuthenticated = function () {
        this.user.first_name = 'First';
        this.user.last_name = 'Last';
        this.user.email = '[email protected]';
        this.user.access = 'institution';
        return this.initialized;
    };
}]);

angular.module('myApp').controller('myCtrl', ['$scope', 'userService', function ($scope, userService) {
    $scope.user = userService.user;
    $scope.callUserService = function () {
        userService.isAuthenticated().then(function () {
            $scope.thencalled = true;
        });
    };
}]);

This is where the documentation is:

http://msdn.microsoft.com/en-us/library/dwhawy9k.aspx

The numeric ("N") format specifier converts a number to a string of the form "-d,ddd,ddd.ddd…", where "-" indicates a negative number symbol if required, "d" indicates a digit (0-9) ...

And this is where they talk about the default (2):

http://msdn.microsoft.com/en-us/library/system.globalization.numberformatinfo.numberdecimaldigits.aspx

      // Displays a negative value with the default number of decimal digits (2).
      Int64 myInt = -1234;
      Console.WriteLine( myInt.ToString( "N", nfi ) );

As Leo points out, the code you added to your question would not suggest a strong reference cycle (a.k.a., retain cycle). One operation-related issue that could cause a strong reference cycle would be if the operation is not getting released. While your code snippet suggests that you have not defined your operation to be concurrent, but if you have, it wouldn't be released if you never posted isFinished, or if you had circular dependencies, or something like that. And if the operation isn't released, the view controller wouldn't be released either. I would suggest adding a breakpoint or NSLog in your operation's dealloc method and confirm that's getting called.

You said:

I understand the notion of retain cycles, but I am not quite sure what happens in blocks, so that confuses me a little bit

The retain cycle (strong reference cycle) issues that occur with blocks are just like the retain cycle issues you're familiar with. A block will maintain strong references to any objects that appear within the block, and it will not release those strong references until the block itself is released. Thus, if block references self, or even just references an instance variable of self, that will maintain strong reference to self, that is not resolved until the block is released (or in this case, until the NSOperation subclass is released.

For more information, see the Avoid Strong Reference Cycles when Capturing self section of the Programming with Objective-C: Working with Blocks document.

If your view controller is still not getting released, you simply have to identify where the unresolved strong reference resides (assuming you confirmed the NSOperation is getting deallocated). A common example is the use of a repeating NSTimer. Or some custom delegate or other object that is erroneously maintaining a strong reference. You can often use Instruments to track down where objects are getting their strong references, e.g.:

Or in Xcode 5:

Another way is download and unzip chromedriver and put 'chromedriver.exe' in C:\Program Files\Python38\Scripts and then you need not to provide the path of driver, just

driver= webdriver.Chrome()

Start by reading the fork man page as well as the getppid / getpid man pages.

From fork's

On success, the PID of the child process is returned in the parent's thread of execution, and a 0 is returned in the child's thread of execution. On failure, a -1 will be returned in the parent's context, no child process will be created, and errno will be set appropriately.

So this should be something down the lines of

if ((pid=fork())==0){
    printf("yada yada %u and yada yada %u",getpid(),getppid());
}
else{ /* avoids error checking*/
    printf("Dont yada yada me, im your parent with pid %u ", getpid());
}

As to your question:

This is the child process. My pid is 22163 and my parent's id is 0.

This is the child process. My pid is 22162 and my parent's id is 22163.

fork() executes before the printf. So when its done, you have two processes with the same instructions to execute. Therefore, printf will execute twice. The call to fork() will return 0 to the child process, and the pid of the child process to the parent process.

You get two running processes, each one will execute this instruction statement:

printf ("... My pid is %d and my parent's id is %d",getpid(),0); 

and

printf ("... My pid is %d and my parent's id is %d",getpid(),22163);  

~

To wrap it up, the above line is the child, specifying its pid. The second line is the parent process, specifying its id (22162) and its child's (22163).

One solution, though it won't work in all situations, is to hide the element by setting the opacity to 0. A completely transparent element will have width.

The draw back is that the element will still take up space, but that won't be an issue in all cases.

For example:

$(img).css("opacity", 0)  //element cannot be seen
width = $(img).width()    //but has width

For very advanced JSON objects to HTML tables you can try My jQuery Solution that is based on this closed thread.

To understand the "encoding" attribute, you have to understand the difference between bytes and characters.

Think of bytes as numbers between 0 and 255, whereas characters are things like "a", "1" and "Ä". The set of all characters that are available is called a character set.

Each character has a sequence of one or more bytes that are used to represent it; however, the exact number and value of the bytes depends on the encoding used and there are many different encodings.

Most encodings are based on an old character set and encoding called ASCII which is a single byte per character (actually, only 7 bits) and contains 128 characters including a lot of the common characters used in US English.

For example, here are 6 characters in the ASCII character set that are represented by the values 60 to 65.

Extract of ASCII Table 60-65
+---------------------+
¦ Byte ¦  Character   ¦
¦------+--------------¦
¦  60  ¦      <       ¦
¦  61  ¦      =       ¦
¦  62  ¦      >       ¦
¦  63  ¦      ?       ¦
¦  64  ¦      @       ¦
¦  65  ¦      A       ¦
+---------------------+

In the full ASCII set, the lowest value used is zero and the highest is 127 (both of these are hidden control characters).

However, once you start needing more characters than the basic ASCII provides (for example, letters with accents, currency symbols, graphic symbols, etc.), ASCII is not suitable and you need something more extensive. You need more characters (a different character set) and you need a different encoding as 128 characters is not enough to fit all the characters in. Some encodings offer one byte (256 characters) or up to six bytes.

Over time a lot of encodings have been created. In the Windows world, there is CP1252, or ISO-8859-1, whereas Linux users tend to favour UTF-8. Java uses UTF-16 natively.

One sequence of byte values for a character in one encoding might stand for a completely different character in another encoding, or might even be invalid.

For example, in ISO 8859-1, â is represented by one byte of value 226, whereas in UTF-8 it is two bytes: 195, 162. However, in ISO 8859-1, 195, 162 would be two characters, Ã, ¢.

Think of XML as not a sequence of characters but a sequence of bytes.

Imagine the system receiving the XML sees the bytes 195, 162. How does it know what characters these are?

In order for the system to interpret those bytes as actual characters (and so display them or convert them to another encoding), it needs to know the encoding used in the XML.

Since most common encodings are compatible with ASCII, as far as basic alphabetic characters and symbols go, in these cases, the declaration itself can get away with using only the ASCII characters to say what the encoding is. In other cases, the parser must try and figure out the encoding of the declaration. Since it knows the declaration begins with <?xml it is a lot easier to do this.

Finally, the version attribute specifies the XML version, of which there are two at the moment (see Wikipedia XML versions. There are slight differences between the versions, so an XML parser needs to know what it is dealing with. In most cases (for English speakers anyway), version 1.0 is sufficient.

In this case, myvar should be a boolean value. If this variable is true, it will show the div, if it's false.. It will hide.

HTML is in its basic form just XML. You could Parse your text in an XmlDocument object, and on the root element call InnerText to extract the text. This will strip all HTML tages in any form and also deal with special characters like <   all in one go.

You could also use the !important feature of css to make qualities you do not want to override in the original class. I am using this on my site to keep some of the essential characteristics of the original class while overriding others:

<div class="foo bar">
.foo {
color: blue;
width: 200px  !important;
}

.bar {
color: red;
width: 400px;
}

This will generate a class "foo bar" element that is red and 200px. This is great if you are using the other two classes individually and just want a piece from each class.

On the Mac you can store the passphrase for your private ssh key in your Keychain, which makes the use of it transparent. If you're logged in, it is available, when you are logged out your root user cannot use it. Removing the passphrase is a bad idea because anyone with the file can use it.

First of all, sets have permutations, not strings or integers, so I'll just assume you mean "the set of characters in a string."

Note that a set of size n has n! n-permutations.

The following pseudocode (from Wikipedia), called with k = 1...n! will give all the permutations:

function permutation(k, s) {
    for j = 2 to length(s) {
        swap s[(k mod j) + 1] with s[j]; // note that our array is indexed starting at 1
        k := k / j; // integer division cuts off the remainder
    }
    return s;
}

Here's the equivalent Python code (for 0-based array indexes):

def permutation(k, s):
    r = s[:]
    for j in range(2, len(s)+1):
        r[j-1], r[k%j] = r[k%j], r[j-1]
        k = k/j+1
    return r

For an iBeacon with ProximityUUID E2C56DB5-DFFB-48D2-B060-D0F5A71096E0, major 0, minor 0, and calibrated Tx Power of -59 RSSI, the transmitted BLE advertisement packet looks like this:

d6 be 89 8e 40 24 05 a2 17 6e 3d 71 02 01 1a 1a ff 4c 00 02 15 e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 00 00 00 00 c5 52 ab 8d 38 a5

This packet can be broken down as follows:

d6 be 89 8e # Access address for advertising data (this is always the same fixed value)
40 # Advertising Channel PDU Header byte 0.  Contains: (type = 0), (tx add = 1), (rx add = 0)
24 # Advertising Channel PDU Header byte 1.  Contains:  (length = total bytes of the advertising payload + 6 bytes for the BLE mac address.)
05 a2 17 6e 3d 71 # Bluetooth Mac address (note this is a spoofed address)
02 01 1a 1a ff 4c 00 02 15 e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 00 00 00 00 c5 # Bluetooth advertisement
52 ab 8d 38 a5 # checksum

The key part of that packet is the Bluetooth Advertisement, which can be broken down like this:

02 # Number of bytes that follow in first AD structure
01 # Flags AD type
1A # Flags value 0x1A = 000011010  
   bit 0 (OFF) LE Limited Discoverable Mode
   bit 1 (ON) LE General Discoverable Mode
   bit 2 (OFF) BR/EDR Not Supported
   bit 3 (ON) Simultaneous LE and BR/EDR to Same Device Capable (controller)
   bit 4 (ON) Simultaneous LE and BR/EDR to Same Device Capable (Host)
1A # Number of bytes that follow in second (and last) AD structure
FF # Manufacturer specific data AD type
4C 00 # Company identifier code (0x004C == Apple)
02 # Byte 0 of iBeacon advertisement indicator
15 # Byte 1 of iBeacon advertisement indicator
e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 # iBeacon proximity uuid
00 00 # major 
00 00 # minor 
c5 # The 2's complement of the calibrated Tx Power

Any Bluetooth LE device that can be configured to send a specific advertisement can generate the above packet. I have configured a Linux computer using Bluez to send this advertisement, and iOS7 devices running Apple's AirLocate test code pick it up as an iBeacon with the fields specified above. See: Use BlueZ Stack As A Peripheral (Advertiser)

This blog has full details about the reverse engineering process.

Instead of using re.search use re.findall it will return you all matches in a List. Or you could also use re.finditer (which i like most to use) it will return an Iterator Object and you can just use it to iterate over all found matches.

line = 'bla bla bla<form>Form 1</form> some text...<form>Form 2</form> more text?'
for match in re.finditer('<form>(.*?)</form>', line, re.S):
    print match.group(1)

You need to first run initdb. It will create the database cluster and the initial setup

See How to configure postgresql for the first time? and http://www.postgresql.org/docs/8.4/static/app-initdb.html

It also depends on what you need. For basic SQL transactions you could try doing TSQL transactions by using BEGIN TRANS and COMMIT TRANS in your code. That is the easiest way but it does have complexity and you have to be careful to commit properly (and rollback).

I would use something like

SQLTransaction trans = null;
using(trans = new SqlTransaction)
{
    ...
    Do SQL stuff here passing my trans into my various SQL executers
    ...
    trans.Commit  // May not be quite right
}

Any failure will pop you right out of the using and the transaction will always commit or rollback (depending on what you tell it to do). The biggest problem we faced was making sure it always committed. The using ensures the scope of the transaction is limited.

CSS:

#sidebar {float: right; width: 200px; background: #eee;}
#content {overflow: hidden; background: #dad;}

HTML:

<div id="sidebar">I'm 200px wide</div>
<div id="content"> I take up the remaining space <br> and I don't wrap under the right column</div>

The above should work, you can put that code in wrapper if you want the give it width and center it too, overflow:hidden on the column without a width is the key to getting it to contain, vertically, as in not wrap around the side columns (can be left or right)

IE6 might need zoom:1 set on the #content div too if you need it's support

I am sure there is a direct way (calling functions on your extension directly, or by using the JS classes for extensions), but an indirect method (until something better comes along):

Have your Chrome extension look for a specific DIV or other element on your page, with a very specific ID.

For example:

<div id="ExtensionCheck_JamesEggersAwesomeExtension"></div>

Do a getElementById and set the innerHTML to the version number of your extension or something. You can then read the contents of that client-side.

Again though, you should use a direct method if there is one available.

EDIT: Direct method found!!

Use the connection methods found here: https://developer.chrome.com/extensions/extension#global-events

Untested, but you should be able to do...

var myPort=chrome.extension.connect('yourextensionid_qwerqweroijwefoijwef', some_object_to_send_on_connect);

By stacking each switch case, you achieve the OR condition.

switch(myvar)
{
    case 2:
    case 5:
    ...
    break;

    case 7:
    case 12:
    ...
    break;
    ...
}

Have you seen CAT.NET?

From the blurb -

CAT.NET is a binary code analysis tool that helps identify common variants of certain prevailing vulnerabilities that can give rise to common attack vectors such as Cross-Site Scripting (XSS), SQL Injection and XPath Injection.

I used an early beta and it did seem to turn up a few things worth looking at.

You can accomplish this in a very back-handed way with the following code:

exports.getStaticCompanies = function () {
    var ids = [46128, 2865, 49569, 1488, 45600, 61991, 1418, 61919, 53326, 61680]
    return Company.findAll({
        where: {
            id: ids
        },
        attributes: ['id', 'logo_version', 'logo_content_type', 'name', 'updated_at'],
        order: sequelize.literal('(' + ids.map(function(id) {
            return '"Company"."id" = \'' + id + '\'');
        }).join(', ') + ') DESC')
    });
};

This is somewhat limited because it's got very bad performance characteristics past a few dozen records, but it's acceptable at the scale you're using.

This will produce a SQL query that looks something like this:

[...] ORDER BY ("Company"."id"='46128', "Company"."id"='2865', "Company"."id"='49569', [...])

PHP has libraries: http://ca.php.net/ldap

PEAR also has a number of packages: http://pear.php.net/search.php?q=ldap&in=packages&x=0&y=0

I haven't used either, but I was going to at one point and they seemed like they should work.

Actually there is an operator for that in PostgreSQL:

SELECT *
FROM table
WHERE lower(value) ~~ ANY('{%foo%,%bar%,%baz%}');

I like this solution best. Simple, scalable, responsive. The idea here is to create a zero-height outer div with bottom padding set to the aspect ratio of the video. The iframe is scaled to 100% in both width and height, completely filling the outer container. The outer container automatically adjusts its height according to its width, and the iframe inside adjusts itself accordingly.

<div style="position:relative; width:100%; height:0px; padding-bottom:56.25%;">
    <iframe style="position:absolute; left:0; top:0; width:100%; height:100%"
        src="http://www.youtube.com/embed/RksyMaJiD8Y">
    </iframe>
</div>

The only variable here is the padding-bottom value in the outer div. It's 75% for 4:3 aspect ratio videos, and 56.25% for widescreen 16:9 aspect ratio videos.

Some answers already pointed out background-size: cover is useful in the case, but none points out the browser support details. Here it is:

Add this CSS into your stylesheet:

body {
    background: url(background.jpg) no-repeat center center fixed;
    background-size: cover; /* for IE9+, Safari 4.1+, Chrome 3.0+, Firefox 3.6+ */
    -webkit-background-size: cover; /* for Safari 3.0 - 4.0 , Chrome 1.0 - 3.0 */
    -moz-background-size: cover; /* optional for Firefox 3.6 */ 
    -o-background-size: cover; /* for Opera 9.5 */
    margin: 0; /* to remove the default white margin of body */
    padding: 0; /* to remove the default white margin of body */
}

-moz-background-size: cover; is optional for Firefox, as Firefox starts supporting the value cover since version 3.6. If you need to support Konqueror 3.5.4+ as well, add -khtml-background-size: cover;.

As you're using CSS3, it's suggested to change your DOCTYPE to HTML5. Also, HTML5 CSS Reset stylesheet is suggested to be added BEFORE your our stylesheet to provide a consistent look & feel for modern browsers.

Reference: background-size at MDN

If you ever need to support old browsers like IE 8 or below, you can still go for Javascript way (scroll down to jQuery section)

Last, if you predict your users will use mobile phones to browse your website, do not use the same background image for mobile web, as your desktop image is probably large in file size, which will be a burden to mobile network usage. Use media query to branch CSS.

You have to make sure your DLL is in the classpath.

One such way to do so is to put the path to the DLL in PATH environment variable.

Other option is to add it to the VM arguments in the variable LD_LIBRARY_PATH, like this:

java -Djava.library.path=/path/to/my/dll -cp /my/classpath/goes/here MainClass

Try this test:

any(substring in string for substring in substring_list)

It will return True if any of the substrings in substring_list is contained in string.

Note that there is a Python analogue of Marc Gravell's answer in the linked question:

from itertools import imap
any(imap(string.__contains__, substring_list)) 

In Python 3, you can use map directly instead:

any(map(string.__contains__, substring_list))

Probably the above version using a generator expression is more clear though.

this.setState({
    name:'value' 
},() => {
    console.log(this.state.name);
});

Use newtonsoft like so:

using System.Collections.Generic;
using System.Linq;
using Newtonsoft.Json.Linq;

    static void Main()

        var resultObjects = AllChildren(JObject.Parse(json))
            .First(c => c.Type == JTokenType.Array && c.Path.Contains("results"))
            .Children<JObject>();

        foreach (JObject result in resultObjects) {
            foreach (JProperty property in result.Properties()) {
                // do something with the property belonging to result
            }
        }
    }

I meet the same problem.Select theme to another one in preview can solve problem temporary.Like the image

Finally,I found out that there are AppTheme and AppBaseTheme in my styles.xml. And AppTheme has parent AppBaseTheme. The AppBaseTheme has parent of one system style.

And every layout file use the theme AppTheme. Just change AppTheme's parent to AppBaseTheme's parent. It solve the problem permanent.

I posted my answer even though another answer has already been accepted; the accepted answer relies on a deprecated function; additionally, this deprecated function is based on Singular Value Decomposition (SVD), which (although perfectly valid) is the much more memory- and processor-intensive of the two general techniques for calculating PCA. This is particularly relevant here because of the size of the data array in the OP. Using covariance-based PCA, the array used in the computation flow is just 144 x 144, rather than 26424 x 144 (the dimensions of the original data array).

Here's a simple working implementation of PCA using the linalg module from SciPy. Because this implementation first calculates the covariance matrix, and then performs all subsequent calculations on this array, it uses far less memory than SVD-based PCA.

(the linalg module in NumPy can also be used with no change in the code below aside from the import statement, which would be from numpy import linalg as LA.)

The two key steps in this PCA implementation are:

• calculating the covariance matrix; and

• taking the eivenvectors & eigenvalues of this cov matrix

In the function below, the parameter dims_rescaled_data refers to the desired number of dimensions in the rescaled data matrix; this parameter has a default value of just two dimensions, but the code below isn't limited to two but it could be any value less than the column number of the original data array.

def PCA(data, dims_rescaled_data=2):
    """
    returns: data transformed in 2 dims/columns + regenerated original data
    pass in: data as 2D NumPy array
    """
    import numpy as NP
    from scipy import linalg as LA
    m, n = data.shape
    # mean center the data
    data -= data.mean(axis=0)
    # calculate the covariance matrix
    R = NP.cov(data, rowvar=False)
    # calculate eigenvectors & eigenvalues of the covariance matrix
    # use 'eigh' rather than 'eig' since R is symmetric, 
    # the performance gain is substantial
    evals, evecs = LA.eigh(R)
    # sort eigenvalue in decreasing order
    idx = NP.argsort(evals)[::-1]
    evecs = evecs[:,idx]
    # sort eigenvectors according to same index
    evals = evals[idx]
    # select the first n eigenvectors (n is desired dimension
    # of rescaled data array, or dims_rescaled_data)
    evecs = evecs[:, :dims_rescaled_data]
    # carry out the transformation on the data using eigenvectors
    # and return the re-scaled data, eigenvalues, and eigenvectors
    return NP.dot(evecs.T, data.T).T, evals, evecs

def test_PCA(data, dims_rescaled_data=2):
    '''
    test by attempting to recover original data array from
    the eigenvectors of its covariance matrix & comparing that
    'recovered' array with the original data
    '''
    _ , _ , eigenvectors = PCA(data, dim_rescaled_data=2)
    data_recovered = NP.dot(eigenvectors, m).T
    data_recovered += data_recovered.mean(axis=0)
    assert NP.allclose(data, data_recovered)


def plot_pca(data):
    from matplotlib import pyplot as MPL
    clr1 =  '#2026B2'
    fig = MPL.figure()
    ax1 = fig.add_subplot(111)
    data_resc, data_orig = PCA(data)
    ax1.plot(data_resc[:, 0], data_resc[:, 1], '.', mfc=clr1, mec=clr1)
    MPL.show()

>>> # iris, probably the most widely used reference data set in ML
>>> df = "~/iris.csv"
>>> data = NP.loadtxt(df, delimiter=',')
>>> # remove class labels
>>> data = data[:,:-1]
>>> plot_pca(data)

The plot below is a visual representation of this PCA function on the iris data. As you can see, a 2D transformation cleanly separates class I from class II and class III (but not class II from class III, which in fact requires another dimension).

Sure you can. Something like:

HTML

<div ng-controller="fessCntrl">    
     <label ng-repeat="(key,val) in list">
       <input type="radio" name="localityTypeRadio" ng-model="$parent.localityTypeRadio" ng-value="key" />{{key}}
         <div ng-if="key == 'City' || key == 'County'">
             <pre>City or County !!! {{$parent.localityTypeRadio}}</pre>
         </div>
         <div ng-if="key == 'Town'">
             <pre>Town!!! {{$parent.localityTypeRadio}}</pre>
         </div>        
      </label>
</div>

JS

var fessmodule = angular.module('myModule', []);

fessmodule.controller('fessCntrl', function ($scope) {

    $scope.list = {
        City: [{name: "cityA"}, {name: "cityB"}],
        County: [{ name: "countyA"}, {name: "countyB"}],
        Town: [{ name: "townA"}, {name: "townB"}]
      };

    $scope.localityTypeRadio = 'City';
});

fessmodule.$inject = ['$scope'];

Demo Fiddle

Yes, you just need to add a parenthesis :

SELECT col1 as a, (CASE WHEN a = 'test' THEN 'yes' END) as value FROM table;

public static void main(final String[] argv) 
{
    String str;

    str = "hello\r\n\tjava\r\nbook";
    str = str.replaceAll("(\\r|\\n|\\t)", "");
    System.out.println(str);
}

It would be useful to add the tabulation in regex too.

The accepted solution will not actually work. You will notice that the content div will be equal to the height of its parent, body. So setting the body height to 100% will set it equal to the height of the browser window. Let's say the browser window was 768px in height, by setting the content div height to 100%, the div's height will in turn be 768px. Thus, you will end up with the header div being 150px and the content div being 768px. In the end you will have content 150px below the bottom of the page. For another solution, check out this link.

You can do it

DateTime dt = DateTime.Now; 
DateTime firstDayOfMonth = new DateTime(dt.Year, date.Month, 1);
DateTime lastDayOfMonth = firstDayOfMonth.AddMonths(1).AddDays(-1);

One simple way is

Comparator<Dog> ageAscendingComp = ...;
Comparator<Dog> ageDescendingComp = Collections.reverseOrder(ageAscendingComp);
// then call the sort method

On a side note, Dog should really not implement Comparator. It means you have to do strange things like

Collections.sort(myList, new Dog("Rex", 4));
// ^-- why is a new dog being made? What are we even sorting by?!
Collections.sort(myList, myList.get(0));
// ^-- or perhaps more confusingly

Rather you should make Compartors as separate classes.

eg.

public class DogAgeComparator implments Comparator<Dog> {
    public int compareTo(Dog d1, Dog d2) {
        return d1.getAge() - d2.getAge();
    }
}

This has the added benefit that you can use the name of the class to say how the Comparator will sort the list. eg.

Collections.sort(someDogs, new DogNameComparator());
// now in name ascending order

Collections.sort(someDogs, Collections.reverseOrder(new DogAgeComparator()));
// now in age descending order

You should also not not have Dog implement Comparable. The Comparable interface is used to denote that there is some inherent and natural way to order these objects (such as for numbers and strings). Now this is not the case for Dog objects as sometimes you may wish to sort by age and sometimes you may wish to sort by name.

You need to give it a container with a height. width uses the viewport as the default width

java 1.6.0_21 or later, or so...

$ java -XX:+PrintFlagsFinal -version 2>&1 | grep MaxHeapSize
uintx MaxHeapSize                         := 12660904960      {product}

It looks like the min(1G) has been removed.

Or on Windows using findstr

C:\>java -XX:+PrintFlagsFinal -version 2>&1 | findstr MaxHeapSize

I know this topic is old, but there are no correct answers.

rotation transform rotates the element from its center, so, a wider element will rotate this way:

Applying overflow: hidden hides the longest dimension as you can see here:

img{_x000D_
  border: 1px solid #000;_x000D_
  transform:          rotate(270deg);_x000D_
  -ms-transform:      rotate(270deg);_x000D_
  -moz-transform:     rotate(270deg);_x000D_
  -webkit-transform:  rotate(270deg);_x000D_
  -o-transform:       rotate(270deg);_x000D_
}_x000D_
.imagetest{_x000D_
  overflow: hidden_x000D_
}

<article>_x000D_
<section class="photo">_x000D_

<div class="imagetest">_x000D_
<img src="https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSqVNRUwpfOwZ5n4kvVXea2VHd6QZGACVVaBOl5aJ2EGSG-WAIF" width=100%/>_x000D_
</div>_x000D_
</section>_x000D_
</article>

So, what I do is some calculations, in my example the picture is 455px width and 111px height and we have to add some margins based on these dimensions:

• left margin: (width - height)/2
• top margin: (height - width)/2

in CSS:

margin: calc((455px - 111px)/2) calc((111px - 455px)/2);

Result:

img{_x000D_
  border: 1px solid #000;_x000D_
  transform:          rotate(270deg);_x000D_
  -ms-transform:      rotate(270deg);_x000D_
  -moz-transform:     rotate(270deg);_x000D_
  -webkit-transform:  rotate(270deg);_x000D_
  -o-transform:       rotate(270deg);_x000D_
  /* 455 * 111 */_x000D_
  margin: calc((455px - 111px)/2) calc((111px - 455px)/2);_x000D_
}

I hope it helps someone!

It seems like Error -38 means a state-exception (as the error-message indicates). For example if you call start(), before the song was ready, or when you call pause(), even if the song isn't playing at all.

To fix this issue check the state of the mediaPlayer before calling the methods. For example:

if(mediaPlayer.isPlaying()) {
    mediaPlayer.pause();
}

Additionally, the MediaPlayer is sending event-messages. Even if you do not need the prepared-event (although it would be a good idea to not start the playback before this event was fired) you must set a callback-listener. This also holds true for the OnErrorListener, OnCompletionListener, OnPreparedListener and OnSeekCompletedListener (if you call the seek method).

Listeners can be attached simply by

mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
    @Override
    public void onPrepared(MediaPlayer mp) {
        // Do something. For example: playButton.setEnabled(true);
    }
});

As of pip 10, the accepted answer will no longer work. The development team has removed access to the get_installed_distributions routine. There is an alternate function in the setuptools for doing the same thing. Here is an alternate version that works with pip 10:

import pkg_resources
installed_packages = pkg_resources.working_set
installed_packages_list = sorted(["%s==%s" % (i.key, i.version)
     for i in installed_packages])
print(installed_packages_list)

Please let me know if it will or won't work in previous versions of pip, too.

If valuationId and user are JavaScript variables, and the source code is plain static HTML, not generated by any means, you should try:

<a href=# onclick="return ReAssign(valuationId,user)">Re-Assign</a>

If they are generated from PHP, and they contain string values, use the escaped quoting around each variables like this:

<?php
    echo '<a href=# onclick="return ReAssign(\'' + $valuationId + '\',\'' + $user + '\')">Re-Assign</a>';
?>

The logic is similar to the updated code in the question, which generates code using JavaScript (maybe using jQuery?): don't forget to apply the escaped quotes to each variable:

var user = element.UserName;
var valuationId = element.ValuationId;
$('#ValuationAssignedTable').append('<tr> <td><a href=# onclick="return ReAssign(\'' + valuationId + '\',\'' + user + '\')">Re-Assign</a> </td>  </tr>');

The moral of the story is

'someString(\''+'otherString'+','+'yetAnotherString'+'\')'

Will get evaluated as:

someString('otherString,yetAnotherString');

Whereas you would need:

someString('otherString','yetAnotherString');

This should work:

DateTime.Now.ToString("hh.mm.ss.ffffff");

If you don't need it to be displayed and just need to know the time difference, well don't convert it to a String. Just leave it as, DateTime.Now();

And use TimeSpan to know the difference between time intervals:

Example

DateTime start;
TimeSpan time;

start = DateTime.Now;

//Do something here

time = DateTime.Now - start;
label1.Text = String.Format("{0}.{1}", time.Seconds, time.Milliseconds.ToString().PadLeft(3, '0'));

document.getElementById('child') should return you the correct element - remember that id's need to be unique across a document to make it valid anyway.

edit : see this page - ids MUST be unique.

edit edit : alternate way to solve the problem :

<div onclick="test('child1')">
    Test
    <div id="child1">child</div>
</div>

then you just need the test() function to look up the element by id that you passed in.

You can use %~dp0 to get the path of the currently running batch file.

Edited to change directory to the VBS location before running

If you want the VBS to synchronously run in the same window, then

@echo off
pushd %~dp0
cscript necdaily.vbs

If you want the VBS to synchronously run in a new window, then

@echo off
pushd %~dp0
start /wait "" cmd /c cscript necdaily.vbs

If you want the VBS to asynchronously run in the same window, then

@echo off
pushd %~dp0
start /b "" cscript necdaily.vbs

If you want the VBS to asynchronously run in a new window, then

@echo off
pushd %~dp0
start "" cmd /c cscript necdaily.vbs

The best solution that worked great for me.

You have to: Copy this code to your main CSS file,

.responsive-video {
    position: relative;
    padding-bottom: 56.25%;
    padding-top: 60px; overflow: hidden;
}

.responsive-video iframe,
.responsive-video object,
.responsive-video embed {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

and then put your embeded video to

<div class="responsive-video">
    <iframe ></iframe>
</div>

That’s it! Now you can use responsive videos on your site.

I had similar issues browsing to secure sites (https://) when using Burp (or at least an issue that would bring you to this page when searching Google):

• ssl_error_no_cypher_overlap in Firefox
• ERR_SSL_VERSION_OR_CIPHER_MISMATCH in Chrome

It turned out to be an issue with using Java 8. When I switched to Java 7, the problem stopped.

Solution is to change Delimiter.

Content of the csv file -> Note .. Also space and , in value

Values are 6 Dutch word aap,noot,mies,Piet, Gijs, Jan

Col1;Col2;Col3

a,ap;noo,t;mi es

P,iet;G ,ijs;Ja ,n



$csv = Import-Csv C:\TejaCopy.csv -Delimiter ';' 

Answer:

Write-Host $csv
@{Col1=a,ap; Col2=noo,t; Col3=mi es} @{Col1=P,iet; Col2=G ,ijs; Col3=Ja ,n}

It is possible to read a CSV file and use other Delimiter to separate each column.

It worked for my script :-)

With the -atime, -ctime, and -mtime switches to find, you can get close to what you want to achieve.

The other answers are good: there isn't an assert function built into ECMAScript5 (e.g. JavaScript that works basically everywhere) but some browsers give it to you or have add-ons that provide that functionality. While it's probably best to use a well-established / popular / maintained library for this, for academic purposes a "poor man's assert" function might look something like this:

const assert = function(condition, message) {
    if (!condition)
        throw Error('Assert failed: ' + (message || ''));
};

assert(1 === 1); // Executes without problem
assert(false, 'Expected true');
// Yields 'Error: Assert failed: Expected true' in console

You need commas after end finishing the case statement. And, the "as" goes after the case statement, not inside it:

Insert into TblStuff(FullName, Address, City, Zip)
    Select (Case When Middle is Null Then Fname + LName
                 Else Fname +' ' + Middle + ' '+ Lname
            End)  as FullName,
           (Case When Address2 is Null Then Address1
                 else Address1 +', ' + Address2
            End)  as  Address,
           City as City,
           Zip as Zip
    from tblImport

I also had to deal with this problem, so here my solution. It works great for me.

1. Create class DelegateCommand

    public class DelegateCommand<T> : ICommand
{
    private Predicate<T> _canExecuteMethod;
    private readonly Action<T> _executeMethod;
    public event EventHandler CanExecuteChanged;

    public DelegateCommand(Action<T> executeMethod) : this(executeMethod, null)
    {
    }
    public DelegateCommand(Action<T> executeMethod, Predicate<T> canExecuteMethod)
    {
        this._canExecuteMethod = canExecuteMethod;
        this._executeMethod = executeMethod ?? throw new ArgumentNullException(nameof(executeMethod), "Command is not specified."); 
    }


    public void RaiseCanExecuteChanged()
    {
        if (this.CanExecuteChanged != null)
            CanExecuteChanged(this, null);
    }
    public bool CanExecute(object parameter)
    {
        return _canExecuteMethod == null || _canExecuteMethod((T)parameter) == true;
    }

    public void Execute(object parameter)
    {
        _executeMethod((T)parameter);
    }
}

2. Define your command

        public DelegateCommand<Window> CloseWindowCommand { get; private set; }


    public MyViewModel()//ctor of your viewmodel
    {
        //do something

        CloseWindowCommand = new DelegateCommand<Window>(CloseWindow);


    }
        public void CloseWindow(Window win) // this method is also in your viewmodel
    {
        //do something
        win?.Close();
    }

3. Bind your command in the view

public MyView(Window win) //ctor of your view, window as parameter
    {
        InitializeComponent();
        MyButton.CommandParameter = win;
        MyButton.Command = ((MyViewModel)this.DataContext).CloseWindowCommand;
    }

4. And now the window

  Window win = new Window()
        {
            Title = "My Window",
            Height = 800,
            Width = 800,
            WindowStartupLocation = WindowStartupLocation.CenterScreen,

        };
        win.Content = new MyView(win);
        win.ShowDialog();

so thats it, you can also bind the command in the xaml file and find the window with FindAncestor and bind it to the command parameter.

For +300k concurrent connection:

Set these variables in /etc/sysctl.conf:

fs.file-max = 10000000 
fs.nr_open = 10000000

Also, change these variables in /etc/security/limits.conf:

* soft nofile 10000000
* hard nofile 10000000
root soft nofile 10000000
root hard nofile 10000000

And finally, increase TCP buffers in /etc/sysctl.conf, too:

net.ipv4.tcp_mem = 786432 1697152 1945728
net.ipv4.tcp_rmem = 4096 4096 16777216
net.ipv4.tcp_wmem = 4096 4096 16777216

for more information please refer to this.

if you are adding multiple items to the list use this:

mAdapter.notifyItemRangeInserted(startPosition, itemcount);

This notify any registered observers that the currently reflected itemCount items starting at positionStart have been newly inserted. The item previously located at positionStart and beyond can now be found starting at position positinStart+itemCount

existing item in the dataset still considered up to date.

First off, that warning does not always mean so much. I usually disabled it after making sure it's not a performance bottle neck. It just means the IEnumerable is evaluated twice, wich is usually not a problem unless the evaluation itself takes a long time. Even if it does take a long time, in this case your only using one element the first time around.

In this scenario you could also exploit the powerful linq extension methods even more.

var firstObject = objects.First();
return DoSomeThing(firstObject).Concat(DoSomeThingElse(objects).ToList();

It is possible to only evaluate the IEnumerable once in this case with some hassle, but profile first and see if it's really a problem.

First parameter is stored in EAX register and result also.

function IsNegative(ANum: Integer): LongBool; assembler;
asm
   and eax, $80000000
end;

+ presents one of the relative selectors. Here is a list of all relative selectors:

div p - All <p> elements inside of a <div> element are selected.

div > p - All <p> elements whose direct parent is <div> are selected. It works backwards too (p < div)

div + p - All <p> elements placed immediately after a <div> element are selected.

div ~ p - All <p> elements that are preceded by a <div> element are selected.

Here is some more about selectors.

I did that once. Ultimately I found my simplified basicconfig.py adequate for my needs. You can pass in a namespace with other objects for it to reference if you need to. You can also pass in additional defaults from your code. It also maps attribute and mapping style syntax to the same configuration object.

While there is a plethora of documentation / tutorials out there, the simple answer for your question is this:

// to create a jQuery function, you basically just extend the jQuery prototype
// (using the fn alias)

$.fn.myfunction = function () {
    // blah
};

Inside that function, the this variable corresponds to the jQuery wrapped set you called your function on. So something like:

$.fn.myfunction = function () {
    console.log(this.length);
};

$('.foo').myfunction();

... will flush to the console the number of elements with the class foo.

Of course, there is a bit more to semantics than that (as well as best practices, and all that jazz), so make sure you read up on it.

You can use SQLAlchemy's or_ function to search in more than one column (the underscore is necessary to distinguish it from Python's own or).

Here's an example:

from sqlalchemy import or_
query = meta.Session.query(User).filter(or_(User.firstname.like(searchVar),
                                            User.lastname.like(searchVar)))

Use the following css:

* {
    font: Verdana, Arial, 'sans-serif' !important;/* <-- fonts */
}

The *-selector means any/all elements, but will obviously be on the bottom of the food chain when it comes to overriding more specific selectors.

Note that the !important-flag will render the font-style for * to be absolute, even if other selectors have been used to set the text (for example, the body or maybe a p).

Assuming you are looking out in Winform, there is a SelectedIndexChanged event for the tab

Now in it you could check for your specific tab and proceed with the logic

private void tab1_SelectedIndexChanged(object sender, EventArgs e)
{
     if (tab1.SelectedTab == tab1.TabPages["tabname"])//your specific tabname
     {
         // your stuff
     }
}

Try this,

IFS=''
while read line
do
    echo $line
done < file.txt

EDIT:

From man bash

IFS - The Internal Field Separator that is used for word
splitting after expansion and to split lines into words
with  the  read  builtin  command. The default value is
``<space><tab><newline>''

You can get the input element and then set its readOnly property to true as follows:

document.getElementById('InputFieldID').readOnly = true;

Specifically, this is what you want:

<script type="text/javascript">
  function onLoadBody() {
    document.getElementById('control_EMAIL').readOnly = true;
  } 
</script>

Call this onLoadBody() function on body tag like:

<body onload="onLoadBody">

I have done exactly this with an ICustomTypeDescriptor interface and a Dictionary.

Implementing ICustomTypeDescriptor for dynamic properties:

I have recently had a requirement to bind a grid view to a record object that could have any number of properties that can be added and removed at runtime. This was to allow a user to add a new column to a result set to enter an additional set of data.

This can be achieved by having each data 'row' as a dictionary with the key being the property name and the value being a string or a class that can store the value of the property for the specified row. Of course having a List of Dictionary objects will not be able to be bound to a grid. This is where the ICustomTypeDescriptor comes in.

By creating a wrapper class for the Dictionary and making it adhere to the ICustomTypeDescriptor interface the behaviour for returning properties for an object can be overridden.

Take a look at the implementation of the data 'row' class below:

Note: In the GetProperties method I Could Cache the PropertyDescriptors once read for performance but as I'm adding and removing columns at runtime I always want them rebuilt

You will also notice in the GetProperties method that the Property Descriptors added for the dictionary entries are of type TestResultPropertyDescriptor. This is a custom Property Descriptor class that manages how properties are set and retrieved. Take a look at the implementation below:

The main properties to look at on this class are GetValue and SetValue. Here you can see the component being casted as a dictionary and the value of the key inside it being Set or retrieved. Its important that the dictionary in this class is the same type in the Row wrapper class otherwise the cast will fail. When the descriptor is created the key (property name) is passed in and is used to query the dictionary to get the correct value.

Taken from my blog at:

ICustomTypeDescriptor Implementation for dynamic properties

I can not use the "int length" constructor for StringBuilder since the length of my CLOB is longer than a int and needs a long value.

If the CLOB length is greater than fits in an int, the CLOB data won't fit in a String either. You'll have to use a streaming approach to deal with this much XML data.

If the actual length of the CLOB is smaller than Integer.MAX_VALUE, just force the long to int by putting (int) in front of it.

If you want to center align an element without knowing it's width and height do:

position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);

Example:

*{_x000D_
  margin:0;_x000D_
  padding:0;_x000D_
}_x000D_
section{_x000D_
  background:red;_x000D_
  height: 100vh;_x000D_
  width: 100vw;_x000D_
}_x000D_
div{  _x000D_
  width: 80vw;_x000D_
  height: 80vh;_x000D_
  background: white;_x000D_
  position: absolute;_x000D_
  top: 50%;_x000D_
  left: 50%;_x000D_
  transform: translate(-50%, -50%);_x000D_
}

<section>_x000D_
  <div>_x000D_
    <h1>Popup</h1>_x000D_
  </div>_x000D_
</section>

I've faced the same issue and want to share how I solved it and why.

As you mentioned there are two problems. The first:

In Asp.Net Core how do I register these services and resolve it at runtime based on some key?

So what options do we have? Folks suggest two:

• Use a custom factory (like _myFactory.GetServiceByKey(key))

• Use another DI engine (like _unityContainer.Resolve<IService>(key))

Is the Factory pattern the only option here?

In fact both options are factories because each IoC Container is also a factory (highly configurable and complicated though). And it seems to me that other options are also variations of the Factory pattern.

So what option is better then? Here I agree with @Sock who suggested using custom factory, and that is why.

First, I always try to avoid adding new dependencies when they are not really needed. So I agree with you in this point. Moreover, using two DI frameworks is worse than creating custom factory abstraction. In the second case you have to add new package dependency (like Unity) but depending on a new factory interface is less evil here. The main idea of ASP.NET Core DI, I believe, is simplicity. It maintains a minimal set of features following KISS principle. If you need some extra feature then DIY or use a corresponding Plungin that implements desired feature (Open Closed Principle).

Secondly, often we need to inject many named dependencies for single service. In case of Unity you may have to specify names for constructor parameters (using InjectionConstructor). This registration uses reflection and some smart logic to guess arguments for the constructor. This also may lead to runtime errors if registration does not match the constructor arguments. From the other hand, when using your own factory you have full control of how to provide the constructor parameters. It's more readable and it's resolved at compile-time. KISS principle again.

The second problem:

How can _serviceProvider.GetService() inject appropriate connection string?

First, I agree with you that depending on new things like IOptions (and therefore on package Microsoft.Extensions.Options.ConfigurationExtensions) is not a good idea. I've seen some discussing about IOptions where there were different opinions about its benifit. Again, I try to avoid adding new dependencies when they are not really needed. Is it really needed? I think no. Otherwise each implementation would have to depend on it without any clear need coming from that implementation (for me it looks like violation of ISP, where I agree with you too). This is also true about depending on the factory but in this case it can be avoided.

The ASP.NET Core DI provides a very nice overload for that purpose:

var mongoConnection = //...
var efConnection = //...
var otherConnection = //...
services.AddTransient<IMyFactory>(
             s => new MyFactoryImpl(
                 mongoConnection, efConnection, otherConnection, 
                 s.GetService<ISomeDependency1>(), s.GetService<ISomeDependency2>())));

Besides executeUpdate() on the parentheses, you must also add a variable to use an SQL statement.

For example:

PreparedStatement pst =  connection.prepareStatement(sql);
int numRowsChanged = pst.executeUpdate(sql);

In general, I break lines before operators, and indent the subsequent lines:

Map<long parameterization> longMap
    = new HashMap<ditto>();

String longString = "some long text"
                  + " some more long text";

To me, the leading operator clearly conveys that "this line was continued from something else, it doesn't stand on its own." Other people, of course, have different preferences.

The only difference between isBlank() and isEmpty() is:

StringUtils.isBlank(" ")       = true //compared string value has space and considered as blank

StringUtils.isEmpty(" ")       = false //compared string value has space and not considered as empty

• Place your cursor at the end of the text.
• Press SHIFT and ->. The cursor will move to the next line.
• Press CTRL-F and type , in "Replace with:" and press ENTER.

You will need to put a quote at the beginning of your first text and the end of your last.

section {
    position: relative;
    width: 50%;
    border: 1px solid;
}
h1 {
    display: inline;
}
div {
    position: relative;
    float:right;
    top: 0;
    right: 0;

}

let's assume your environment name is 'demo' and you are using anaconda and want to create a virtual environment:

(if you want python3)

    conda create -n demo python=3

(if you want python2)

    conda create -n demo python=2

After running above command you have to activate the environment by bellow command:

    source activate demo 

Note, from 2015 onwards, just use backticks for templating

https://stackoverflow.com/a/37245773/294884

let a = `hello ${name}`    // NOTE!!!!!!!! ` not ' or "

Note that it is a backtick, not a quote.

If you want to have something similar, you could create a function:

function parse(str) {
    var args = [].slice.call(arguments, 1),
        i = 0;

    return str.replace(/%s/g, () => args[i++]);
}

Usage:

s = parse('hello %s, how are you doing', my_name);

This is only a simple example and does not take into account different kinds of data types (like %i, etc) or escaping of %s. But I hope it gives you some idea. I'm pretty sure there are also libraries out there which provide a function like this.

Try ftp://test.rebex.net/

It is read-only used for testing Rebex components to list directory and download. Allows also to test FTP/SSL and IMAP.

Username is "demo", password is "password"

See https://test.rebex.net/ for more information.

If the response code isn't 200 or 2xx, use getErrorStream() instead of getInputStream().

You can take all values like this:

$abc = "<script>document.getElementByID('yourid').value</script>";

Simple solution to emit and show message by Exception.

try {
  throw new TypeError("Error message");
}
catch (e){
  console.log((<Error>e).message);//conversion to Error type
}

Caution

Above is not a solution if we don't know what kind of error can be emitted from the block. In such cases type guards should be used and proper handling for proper error should be done - take a look on @Moriarty answer.

Just set the path variable to JDK bin in environment variables.

Variable Name : PATH 
Variable Value : C:\Program Files\Java\jdk1.8.0_31\bin

But the best practice is to set JAVA_HOME and PATH as follow.

Variable Name : JAVA_HOME
Variable Value : C:\Program Files\Java\jdk1.8.0_31

Variable Name : PATH 
Variable Value : %JAVA_HOME%\bin

Another possible answer will be:

When you define the table, with the columns and data it'll have. The column id can have the property AUTO_INCREMENT.

By this method, you don't have to worry about the id, it'll be made automatically.

For example (taken from w3schools )

CREATE TABLE Persons
(
ID int NOT NULL AUTO_INCREMENT,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Address varchar(255),
City varchar(255),
PRIMARY KEY (ID)
)

Hope this will be helpful for someone.

Edit: This is only the part where you define how to generate an automatic ID, to obtain it after created, the previous answers before are right.

@Ichorus's answer is correct for views, but if you want to draw rotated rectangles or text, you can do the following in your onDraw (or onDispatchDraw) callback for your view:

(note that theta is the angle from the x axis of the desired rotation, pivot is the Point that represents the point around which we want the rectangle to rotate, and horizontalRect is the rect's position "before" it was rotated)

canvas.save();
canvas.rotate(theta, pivot.x, pivot.y);
canvas.drawRect(horizontalRect, paint);
canvas.restore();

The classical answer that works in almost every environment is

SELECT ID, Name, blah, blah
FROM TableB TB
LEFT JOIN TableA TA
ON TB.ID=TA.ID
WHERE TA.ID IS NULL

sometimes NOT EXISTS may be not implemented (not working).

Try this and see if you get what you are aiming for:

<div id='page' style='width: 600px'>_x000D_
  <h1 style='border:2px black solid; font-size:42px; width:fit-content; width:-webkit-fit-content; width:-moz-fit-content;'>Title</h1>_x000D_
</div>

For jacoco: use this properties:

-Dsonar.jacoco.excludes=**/*View.java

this seems simpler, but only works on Oracle:

ALTER TABLE [Table] 
ALTER [Column] NUMBER DEFAULT 0 NOT NULL;

in addition, with this, you can also add columns, not just alter it. It updates to the default value (0) in this example, if the value was null.

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

To add to svick's answer, the -m option simply adds a message to your stash, and is entirely optional. Thus, the command

git stash push [paths you wish to stash]

is perfectly valid. So for instance, if I want to only stash changes in the src/ directory, I can just run

git stash push src/

I know this is older but the correct way to do this now is

string Domain = HttpContext.Current.Request.Url.Authority

That will get the DNS or ip address with port for a server.

A similar question is here: Is there a limit to the length of a GET request?

I've hit the limit and on my shared hosting account, but the browser returned a blank page before it got to the server I think.

Go to Control Panel / System / "Advanced" tab / Enviromental Variables

Find variable called PATH in the lower list, and edit it. Add to the end C:\Python27

Open a new cmd window and try now.

For Sublime Text 3, all I had to do was add "highlight_line": true to my user settings file: Preferences -> Settings - User. It was only once that preference was set that all the color scheme lineHighlight settings took effect.

Hopefully this will save someone else some of this same flailing about.

For passing both a function, and any arguments to the function:

from typing import Callable    

def looper(fn: Callable, n:int, *args, **kwargs):
    """
    Call a function `n` times

    Parameters
    ----------
    fn: Callable
        Function to be called.
    n: int
        Number of times to call `func`.
    *args
        Positional arguments to be passed to `func`.
    **kwargs
        Keyword arguments to be passed to `func`.

    Example
    -------
    >>> def foo(a:Union[float, int], b:Union[float, int]):
    ...    '''The function to pass'''
    ...    print(a+b)
    >>> looper(foo, 3, 2, b=4)
    6
    6
    6       
    """
    for i in range(n):
        fn(*args, **kwargs)

Depending on what you are doing, it could make sense to define a decorator, or perhaps use functools.partial.

For Python 3:

ListOfStrings = []
ListOfStrings.append('foo')
ListOfStrings.append('oof')
for idx, item in enumerate(ListOfStrings):
if 'foo' in item:
    ListOfStrings[idx] = "bar"

you can use getopt to handle parameters in your bash script. there are not many explanations for getopt out there. here is an example:

#!/bin/sh

OPTIONS=$(getopt -o hf:gb -l help,file:,foo,bar -- "$@")

if [ $? -ne 0 ]; then
  echo "getopt error"
  exit 1
fi

eval set -- $OPTIONS

while true; do
  case "$1" in
    -h|--help) HELP=1 ;;
    -f|--file) FILE="$2" ; shift ;;
    -g|--foo)  FOO=1 ;;
    -b|--bar)  BAR=1 ;;
    --)        shift ; break ;;
    *)         echo "unknown option: $1" ; exit 1 ;;
  esac
  shift
done

if [ $# -ne 0 ]; then
  echo "unknown option(s): $@"
  exit 1
fi

echo "help: $HELP"
echo "file: $FILE"
echo "foo: $FOO"
echo "bar: $BAR"

Snippet

var data= [
          {a:'you',b:'b',c:'c',d:'c'},
          {a: 'you', b: 'b', c: 'c', d:'c'},
          {a: 'them', b: 'b', c: 'c', d:'c'},
          {a: 'them', b: 'b', c: 'c', d:'c'},

There can be a performance gain by importing variables/local scoping inside of a function. This depends on the usage of the imported thing inside the function. If you are looping many times and accessing a module global object, importing it as local can help.

test.py

X=10
Y=11
Z=12
def add(i):
  i = i + 10

runlocal.py

from test import add, X, Y, Z

    def callme():
      x=X
      y=Y
      z=Z
      ladd=add 
      for i  in range(100000000):
        ladd(i)
        x+y+z

    callme()

run.py

from test import add, X, Y, Z

def callme():
  for i in range(100000000):
    add(i)
    X+Y+Z

callme()

A time on Linux shows a small gain

/usr/bin/time -f "\t%E real,\t%U user,\t%S sys" python run.py 
    0:17.80 real,   17.77 user, 0.01 sys
/tmp/test$ /usr/bin/time -f "\t%E real,\t%U user,\t%S sys" python runlocal.py 
    0:14.23 real,   14.22 user, 0.01 sys

real is wall clock. user is time in program. sys is time for system calls.

For make a list, simply do that

colors=(red orange white "light gray")

Technically is an array, but - of course - it has all list features.
Even python list are implemented with array

Quite an intuitive error message - just need to give the columns in d names

Change to either this

d as 
 (
  select                 
     [duration] = month(clothdeliverydate),                 
     [bkdqty] = SUM(CONVERT(INT, deliveredqty))             
  FROM                 
     barcodetable            
  where                 
     month(clothdeliverydate) is not null                
  group by month(clothdeliverydate)           
 ) 

Or you can explicitly declare the fields in the definition of the cte:

d ([duration], [bkdqty]) as 
 (
  select                 
     month(clothdeliverydate),                 
     SUM(CONVERT(INT, deliveredqty))             
  FROM                 
     barcodetable            
  where                 
     month(clothdeliverydate) is not null                
  group by month(clothdeliverydate)           
 ) 

Read one character at a time (using getc(stdin)) and grow the string (realloc) as you go.

Here's a function I wrote some time ago. Note it's intended only for text input.

char *getln()
{
    char *line = NULL, *tmp = NULL;
    size_t size = 0, index = 0;
    int ch = EOF;

    while (ch) {
        ch = getc(stdin);

        /* Check if we need to stop. */
        if (ch == EOF || ch == '\n')
            ch = 0;

        /* Check if we need to expand. */
        if (size <= index) {
            size += CHUNK;
            tmp = realloc(line, size);
            if (!tmp) {
                free(line);
                line = NULL;
                break;
            }
            line = tmp;
        }

        /* Actually store the thing. */
        line[index++] = ch;
    }

    return line;
}

I think I got it. It's:

"SVN Client Path"  /command:update / path:"My folder path"

Basically, when you serialize arrays or objects you simply turn it to a valid string format so that you can easily store them outside of the php script.

1. Use serialize to save the state of an object in database (lets take the User class as an example) Next unserialize the data to load the previous state back to the object (methods are not serializer you need to include object class to be able to use it)
   • user personalization

Note for object you should use magic __sleep and __wakeup methods. __sleep is called by serialize(). A sleep method will return an array of the values from the object that you want to persist.

__wakeup is called by unserialize(). A wakeup method should take the unserialized values and initialize them in them in the object.

For passing data between php and js you would use json_encode to turn php array to valid json format. Or other way round - use JSON.parese() to convert a output data (string) into valid json object. You would want to do that to make use of local storage. (offline data access)

Consider a skewed binary tree with 3 nodes as 7, 3, 2. For any operation like for searching 2, we have to traverse 3 nodes, for deleting 2 also, we have to traverse 3 nodes and for for inserting 1 also, we have to traverse 3 nodes. So, binary tree has worst case complexity of O(n).

In answer the question heading (found by a google search) and not the re-question To stop the line breaking when you have different heading tags e.g.

<h5 style="display:inline;"> What the... </h5><h1 style="display:inline;"> heck is going on? </h1>

Will give you:

What the...heck is going on?

and not

What the... 
heck is going on?

You probably mistyped a few things. From what I gather, you start with a string such as:

string = "test1, test2, test3, test4, test5"

Then you want to split it to keep only the significant substrings:

array = string.split(/, /)

And in the end you only need all the elements excluding the first one:

# We extract and remove the first element from array
first_element = array.shift

# Now array contains the expected result, you can check it with
puts array.inspect

Did that answer your question ?

Imao put UIImageView on background is not the best idea . In my case i added on controller view other 2 views . First view has [UIColor clearColor] on background, second - color which u want to be transparent (grey in my case).Note that order is important.Then for second view set alpha 0.5(alpha >=0 <=1).Added this to lines in prepareForSegue

infoVC.providesPresentationContextTransitionStyle = YES;
infoVC.definesPresentationContext = YES;

And thats all.

You are pretty confused my friend. There are no LOOPS in SQL, only in PL/SQL. Here's a few examples based on existing Oracle table - copy/paste to see results:

-- Numeric FOR loop --
set serveroutput on -->> do not use in TOAD --
DECLARE
  k NUMBER:= 0;
BEGIN
  FOR i IN 1..10 LOOP
    k:= k+1;
    dbms_output.put_line(i||' '||k);
 END LOOP;
END;
/

-- Cursor FOR loop --
set serveroutput on
DECLARE
   CURSOR c1 IS SELECT * FROM scott.emp;
   i NUMBER:= 0;
BEGIN
  FOR e_rec IN c1 LOOP
  i:= i+1;
    dbms_output.put_line(i||chr(9)||e_rec.empno||chr(9)||e_rec.ename);
  END LOOP;
END;
/

-- SQL example to generate 10 rows --
SELECT 1 + LEVEL-1 idx
  FROM dual
CONNECT BY LEVEL <= 10
/

You could do something like this:

var result = customlist.Where(p => !otherlist.Any(l => p.someproperty == l.someproperty));

My experience shows that the -o option doesn't work properly and that the go-offline goal is far from sufficient to allow a full offline build:

The solution I could validate includes the use of the --legacy-local-repository maven option rather than the -o (offline) one and the use of the local repository in place of the distribution repository

In addition, I had to copy every maven-metadata-maven2_central.xml files of the local-repo into the maven-metadata.xml form expected by maven.

See the solution I found here.
