You can get the bounding box of any element by calling getBoundingClientRect

var rect = document.getElementById("myElement").getBoundingClientRect();

That will return an object with left, top, width and height fields.

I have adapted a bit the solution by @steco, switching the dependency from d3 to jquery and adding the height of the text element as parameter

function wrap(text, width, height) {
  text.each(function(idx,elem) {
    var text = $(elem);
    text.attr("dy",height);
        var words = text.text().split(/\s+/).reverse(),
        word,
        line = [],
        lineNumber = 0,
        lineHeight = 1.1, // ems
        y = text.attr("y"),
        dy = parseFloat( text.attr("dy") ),
        tspan = text.text(null).append("tspan").attr("x", 0).attr("y", y).attr("dy", dy + "em");
    while (word = words.pop()) {
      line.push(word);
      tspan.text(line.join(" "));
      if (elem.getComputedTextLength() > width) {
        line.pop();
        tspan.text(line.join(" "));
        line = [word];
        tspan = text.append("tspan").attr("x", 0).attr("y", y).attr("dy", ++lineNumber * lineHeight + dy + "em").text(word);
      }
    }
  });
}

You can use these queries:

select * from all_tab_privs;
select * from dba_sys_privs;
select * from dba_role_privs;

Each of these tables have a grantee column, you can filter on that in the where criteria:

where grantee = 'A'

To query privileges on objects (e.g. tables) in other schema I propose first of all all_tab_privs, it also has a table_schema column.

If you are logged in with the same user whose privileges you want to query, you can use user_tab_privs, user_sys_privs, user_role_privs. They can be queried by a normal non-dba user.

#This adds 10 seconds from now.
from datetime import datetime
import commands

date_string_command="date +%s"
utc = commands.getoutput(date_string_command)
a_date=datetime.fromtimestamp(float(int(utc))).strftime('%Y-%m-%d %H:%M:%S')
print('a_date:'+a_date)
utc = int(utc)+10
b_date=datetime.fromtimestamp(float(utc)).strftime('%Y-%m-%d %H:%M:%S')
print('b_date:'+b_date)

This is a little more wordy but it comes from date command in unix.

I searched a long night and this is doing the trick:

Modified user-example.php from admin-sdk

$client->setAccessType('offline');
$client->setApprovalPrompt('force');
$authUrl = $client->createAuthUrl();
echo "<a class='login' href='" . $authUrl . "'>Connect Me!</a>";

then you get the code at the redirect url and the authenticating with the code and getting the refresh token

$client()->authenticate($_GET['code']);
echo $client()->getRefreshToken();

You should store it now ;)

When your accesskey times out just do

$client->refreshToken($theRefreshTokenYouHadStored);

Try this:

// convert from bitmap to byte array
public byte[] getBytesFromBitmap(Bitmap bitmap) {
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(CompressFormat.JPEG, 70, stream);
    return stream.toByteArray();
}

// get the base 64 string
String imgString = Base64.encodeToString(getBytesFromBitmap(someImg), 
                       Base64.NO_WRAP);

Imagine you are working on a machine where n was just the right value for it only to be possible to hold two of your arrays in memory at one time, but the total memory available, via disk caching, was still sufficient to hold all four.

Assuming a simple LIFO caching policy, this code:

for(int j=0;j<n;j++){
    a[j] += b[j];
}
for(int j=0;j<n;j++){
    c[j] += d[j];
}

would first cause a and b to be loaded into RAM and then be worked on entirely in RAM. When the second loop starts, c and d would then be loaded from disk into RAM and operated on.

the other loop

for(int j=0;j<n;j++){
    a[j] += b[j];
    c[j] += d[j];
}

will page out two arrays and page in the other two every time around the loop. This would obviously be much slower.

You are probably not seeing disk caching in your tests but you are probably seeing the side effects of some other form of caching.

There seems to be a little confusion/misunderstanding here so I will try to elaborate a little using an example.

Say n = 2 and we are working with bytes. In my scenario we thus have just 4 bytes of RAM and the rest of our memory is significantly slower (say 100 times longer access).

Assuming a fairly dumb caching policy of if the byte is not in the cache, put it there and get the following byte too while we are at it you will get a scenario something like this:

• With

  for(int j=0;j<n;j++){
   a[j] += b[j];
  }
  for(int j=0;j<n;j++){
   c[j] += d[j];
  }
  

• cache a[0] and a[1] then b[0] and b[1] and set a[0] = a[0] + b[0] in cache - there are now four bytes in cache, a[0], a[1] and b[0], b[1]. Cost = 100 + 100.

• set a[1] = a[1] + b[1] in cache. Cost = 1 + 1.
• Repeat for c and d.

• Total cost = (100 + 100 + 1 + 1) * 2 = 404

• With

  for(int j=0;j<n;j++){
   a[j] += b[j];
   c[j] += d[j];
  }
  

• cache a[0] and a[1] then b[0] and b[1] and set a[0] = a[0] + b[0] in cache - there are now four bytes in cache, a[0], a[1] and b[0], b[1]. Cost = 100 + 100.

• eject a[0], a[1], b[0], b[1] from cache and cache c[0] and c[1] then d[0] and d[1] and set c[0] = c[0] + d[0] in cache. Cost = 100 + 100.
• I suspect you are beginning to see where I am going.
• Total cost = (100 + 100 + 100 + 100) * 2 = 800

This is a classic cache thrash scenario.

// implicit cast
var value = parseInt(tbb*1); // see original question

Explanation, for those who don't find it trivial:

Multiplying by one, a method called "implicit cast", attempts to turn the unknown type operand into the primitive type 'number'. In particular, an empty string would become number 0, making it an eligible type for parseInt()...

A very good example was also given above by PirateApp, who suggested to prepend the + sign, forcing JavaScript to use the Number implicit cast.

Aug. 20 update: parseInt("0"+expr); gives better results, in particular for parseInt("0"+'str');

Caveat: It is not necessary to put the implementation in the header file, see the alternative solution at the end of this answer.

Anyway, the reason your code is failing is that, when instantiating a template, the compiler creates a new class with the given template argument. For example:

template<typename T>
struct Foo
{
    T bar;
    void doSomething(T param) {/* do stuff using T */}
};

// somewhere in a .cpp
Foo<int> f; 

When reading this line, the compiler will create a new class (let's call it FooInt), which is equivalent to the following:

struct FooInt
{
    int bar;
    void doSomething(int param) {/* do stuff using int */}
}

Consequently, the compiler needs to have access to the implementation of the methods, to instantiate them with the template argument (in this case int). If these implementations were not in the header, they wouldn't be accessible, and therefore the compiler wouldn't be able to instantiate the template.

A common solution to this is to write the template declaration in a header file, then implement the class in an implementation file (for example .tpp), and include this implementation file at the end of the header.

Foo.h

template <typename T>
struct Foo
{
    void doSomething(T param);
};

#include "Foo.tpp"

Foo.tpp

template <typename T>
void Foo<T>::doSomething(T param)
{
    //implementation
}

This way, implementation is still separated from declaration, but is accessible to the compiler.

Alternative solution

Another solution is to keep the implementation separated, and explicitly instantiate all the template instances you'll need:

Foo.h

// no implementation
template <typename T> struct Foo { ... };

Foo.cpp

// implementation of Foo's methods

// explicit instantiations
template class Foo<int>;
template class Foo<float>;
// You will only be able to use Foo with int or float

If my explanation isn't clear enough, you can have a look at the C++ Super-FAQ on this subject.

As of CMake 3.1+ the developers strongly discourage users from using file(GLOB or file(GLOB_RECURSE to collect lists of source files.

Note: We do not recommend using GLOB to collect a list of source files from your source tree. If no CMakeLists.txt file changes when a source is added or removed then the generated build system cannot know when to ask CMake to regenerate. The CONFIGURE_DEPENDS flag may not work reliably on all generators, or if a new generator is added in the future that cannot support it, projects using it will be stuck. Even if CONFIGURE_DEPENDS works reliably, there is still a cost to perform the check on every rebuild.

See the documentation here.

There are two goods answers ([1], [2]) here on SO detailing the reasons to manually list source files.

It is possible. E.g. with file(GLOB:

cmake_minimum_required(VERSION 2.8)

file(GLOB helloworld_SRC
     "*.h"
     "*.cpp"
)

add_executable(helloworld ${helloworld_SRC})

Note that this requires manual re-running of cmake if a source file is added or removed, since the generated build system does not know when to ask CMake to regenerate, and doing it at every build would increase the build time.

As of CMake 3.12, you can pass the CONFIGURE_DEPENDS flag to file(GLOB to automatically check and reset the file lists any time the build is invoked. You would write:

cmake_minimum_required(VERSION 3.12)

file(GLOB helloworld_SRC CONFIGURE_DEPENDS "*.h" "*.cpp")

This at least lets you avoid manually re-running CMake every time a file is added.

1. Wrap the <input type="file"> with a <label> tag;
2. Add a tag (with the text that you need) inside the label, like a <span> or <a>;
3. Make this tag look like a button;
4. Make input[type="file"] invisible via display: none.

While @perrejba s answer is correct, it uses the legacy C-style functions. As the question is tagged C++, you may want to use a method instead:

inputMat.copyTo(outputMat, maskMat);

All objects are of type cv::Mat.

Please be aware that the masking is binary. Any non-zero value in the mask is interpreted as 'do copy'. Even if the mask is a greyscale image.

Also be aware that the .copyTo() function does not clear the output before copying.

If you want to permanently alter the original Image, you have to do an additional copy/clone/assignment. The copyTo() function is not defined for overlapping input/output images. So you can't use the same image as both input and output.

On my system (Windows 8.1), Sublime 2 shows default font "Consolas". You can find yours by following this procedure:

1. go to View menu and select Show Console
2. Then enter this command: view.settings().get('font_face')

You will find your default font.

Doing this with POSIX is tricky:

• POSIX Sed does not support \r or \15. Even if it did, the in place option -i is not POSIX

• POSIX Awk does support \r and \15, however the -i inplace option is not POSIX

• d2u and dos2unix are not POSIX utilities, but ex is

• POSIX ex does not support \r, \15, \n or \12

To remove carriage returns:

awk 'BEGIN{RS="^$";ORS="";getline;gsub("\r","");print>ARGV[1]}' file

To add carriage returns:

awk 'BEGIN{RS="^$";ORS="";getline;gsub("\n","\r&");print>ARGV[1]}' file

Another alternative that uses an external library is _.has() from Lodash.

E.g.

_.has(a, 'b.c')

is equal to

(a && a.b && a.b.c)

EDIT: As noted in the comments, you lose out on Typescript's type inference when using this method. E.g. Assuming that one's objects are properly typed, one would get a compilation error with (a && a.b && a.b.z) if z is not defined as a field of object b. But using _.has(a, 'b.z'), one would not get that error.

I am going to give you a simplistic answer that hopefully will help you with VBA in general. The easiest way to learn how VBA works and how to reference and access elements is to record your macro then edit it in the VBA editor. This is how I learned VBA. It is based on visual basic so all the programming conventions of VB apply. Recording the macro lets you see how to access and do things.

you could use something like this:

var result = 0
Sheets("Sheet1").Select
result = Range("A1").Value * Range("B1").Value
Sheets("Sheet2").Select
Range("D1").Value = result

Alternatively you can also reference a cell using Cells(1,1).Value This way you can set variables and increment them as you wish. I think I am just not clear on exactly what you are trying to do but i hope this helps.

for Oracle Database 10g users:

alter table mytable modify(mycolumn null);

You get "ORA-01735: invalid ALTER TABLE option" when you try otherwise

ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;

Indirect via Your Server - Calling 3rd Party API - secure and recommended

Your server can call the 3rd Party API after proper authentication and authorization. The API Keys are not exposed to client.

node.js - https://www.npmjs.org/package/node-mandrill

const mandrill = require('node-mandrill')('<your API Key>'); 

function sendEmail ( _name, _email, _subject, _message) {
    mandrill('/messages/send', {
        message: {
            to: [{email: _email , name: _name}],
            from_email: '[email protected]',
            subject: _subject,
            text: _message
        }
    }, function(error, response){
        if (error) console.log( error );
        else console.log(response);
    });
}

// define your own email api which points to your server.

app.post( '/api/sendemail/', function(req, res){
            
    let _name = req.body.name;
    let _email = req.body.email;
    let _subject = req.body.subject;
    let _messsage = req.body.message;

    //implement your spam protection or checks. 

    sendEmail ( _name, _email, _subject, _message );

});

and then use use $.ajax on client to call your email API.

Directly From Client - Calling 3rd Party API - not recomended

Send an email using only JavaScript

in short:

1. register for Mandrill to get an API key
2. load jQuery
3. use $.ajax to send an email

Like this -

function sendMail() {
    $.ajax({
      type: 'POST',
      url: 'https://mandrillapp.com/api/1.0/messages/send.json',
      data: {
        'key': 'YOUR API KEY HERE',
        'message': {
          'from_email': '[email protected]',
          'to': [
              {
                'email': '[email protected]',
                'name': 'RECIPIENT NAME (OPTIONAL)',
                'type': 'to'
              }
            ],
          'autotext': 'true',
          'subject': 'YOUR SUBJECT HERE!',
          'html': 'YOUR EMAIL CONTENT HERE! YOU CAN USE HTML!'
        }
      }
     }).done(function(response) {
       console.log(response); // if you're into that sorta thing
     });
}

Note: Keep in mind that your API key is visible to anyone, so any malicious user may use your key to send out emails that can eat up your quota.

A simple restart fixed it for me. I'm not sure what was the problem since I work with so much software but I have a feeling it was the VPN software or maybe the fact I put my laptop in sleep a lot and some file was corrupted. I really don't know but the restart fixed it.

If you need that method in another controller, that means you need to abstract it and make it reusable. Move that implementation into a service class (ReportingService or something similar) and inject it into your controllers.

Example:

class ReportingService
{
  public function getPrintReport()
  {
    // your implementation here.
  }
}
// don't forget to import ReportingService at the top (use Path\To\Class)
class SubmitPerformanceController extends Controller
{
  protected $reportingService;
  public function __construct(ReportingService $reportingService)
  {
     $this->reportingService = $reportingService;
  }

  public function reports() 
  {
    // call the method 
    $this->reportingService->getPrintReport();
    // rest of the code here
  }
}

Do the same for the other controllers where you need that implementation. Reaching for controller methods from other controllers is a code smell.

You could subscribe to the TextChanged event on the TextBox and if the text is empty set the Button to disabled. Or you could bind the Button.IsEnabled property to the TextBox.Text property and use a converter that returns true if there is any text and false otherwise.

The following was all done in cygwin on a Windows XP box.

This will get your IP address. Note that there are backquotes around the hostname command, not single quotes.

ping -n 1 `hostname` | grep "Reply from " | cut -f 3 -d " " | cut -f 1 -d ":"

This will get your subnet.

ping -n 1 `hostname` | grep "Reply from " | cut -f 3 -d " " | cut -f "1 2 3" -d "."

The following will list all hosts on your local network (put it into a script called "netmap"). I had taken the subnet line above and put it into an executable called "getsubnet", which I then called from the following script.

MINADDR=0
MAXADDR=255
SUBNET=`getsubnet`

hostcnt=0

echo Pinging all addresses in ${SUBNET}.${MINADDR}-${MAXADDR}

for i in `seq $MINADDR $MAXADDR`; do
addr=${SUBNET}.$i
ping -n 1 -w 0 $addr > /dev/null

if [ $? -ne 1 ]    
then    
echo $addr UP    
hostcnt=$((hostcnt+1))    
fi

done

echo Found $hostcnt hosts on subnet ${SUBNET}.${MINADDR}-${MAXADDR}

DataTable.NewRow will initialize each field to:

• the default value for each DataColumn (DataColumn.DefaultValue)

• except for auto-increment columns (DataColumn.AutoIncrement == true), which will be initialized to the next auto-increment value.

• and expression columns (DataColumn.Expression.Length > 0) are also a special case; the default value will depend on the default values of columns on which the expression is calculated.

So you should probably be checking something like:

bool isDirty = false;
for (int i=0; i<table.Columns.Count; i++)
{
    if (table.Columns[i].Expression.Length > 0) continue;
    if (table.Columns[i].AutoIncrement) continue;
    if (row[i] != table.Columns[i].DefaultValue) isDirty = true;
}

I'll leave the LINQ version as an exercise :)

If linking to the shell Lightweight API (shlwapi.dll) is ok for you, you can use the PathIsDirectory function

Do something like this:

A <div> with ID of #imageDIV, another one with ID #download and a hidden <div> with ID #previewImage.

Include the latest version of jquery, and jspdf.debug.js from the jspdf CDN

Then add this script:

var element = $("#imageDIV"); // global variable
var getCanvas; // global variable
$('document').ready(function(){
  html2canvas(element, {
    onrendered: function (canvas) {
      $("#previewImage").append(canvas);
      getCanvas = canvas;
    }
  });
});
$("#download").on('click', function () {
  var imgageData = getCanvas.toDataURL("image/png");
  // Now browser starts downloading it instead of just showing it
  var newData = imageData.replace(/^data:image\/png/, "data:application/octet-stream");
  $("#download").attr("download", "image.png").attr("href", newData);
});

The div will be saved as a PNG on clicking the #download

^[A-Za-z0-9_.]+$

From beginning until the end of the string, match one or more of these characters.

Edit:

Note that ^ and $ match the beginning and the end of a line. When multiline is enabled, this can mean that one line matches, but not the complete string.

Use \A for the beginning of the string, and \z for the end.

See for example: http://msdn.microsoft.com/en-us/library/h5181w5w(v=vs.110).aspx

In my case,it is cause by Realm library,after I update it to latest version(5.1.0 so far) of Realm,the problem solved!

Here is the working gradle script:

buildscript {
repositories {
    jcenter()
    google()
}

dependencies {
    classpath 'com.android.tools.build:gradle:3.1.2'
    classpath "io.realm:realm-gradle-plugin:5.1.0"
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    classpath 'com.google.gms:google-services:3.2.1'
  }
}

The simplest change would be something like this:

public static void main (String[] args) throws Exception {
  testconnect obj = new testconnect();
  obj.con2 = DriverManager.getConnection(obj.getConnectionUrl2());
  obj.con2.close();
}

This sounds to me like what you have is one command with 2 outputs, I would opt for making the change in both client and server for this.

At the client, use JS to build up the URL you want to post to (use JQuery for simplicity) i.e.

<script type="text/javascript">
    $(function() {
        // this code detects a button click and sets an `option` attribute
        // in the form to be the `name` attribute of whichever button was clicked
        $('form input[type=submit]').click(function() {
            var $form = $('form');
            form.removeAttr('option');
            form.attr('option', $(this).attr('name'));
        });
        // this code updates the URL before the form is submitted
        $("form").submit(function(e) { 
            var option = $(this).attr("option");
            if (option) {
                e.preventDefault();
                var currentUrl = $(this).attr("action");
                $(this).attr('action', currentUrl + "/" + option).submit();     
            }
        });
    });
</script>
...
<input type="submit" ... />
<input type="submit" name="excel" ... />

Now at the server side we can add a new route to handle the excel request

routes.MapRoute(
    name: "ExcelExport",
    url: "SearchDisplay/Submit/excel",
    defaults: new
    {
        controller = "SearchDisplay",
        action = "SubmitExcel",
    });

You can setup 2 distinct actions

public ActionResult SubmitExcel(SearchCostPage model)
{
   ...
}

public ActionResult Submit(SearchCostPage model)
{
   ...
}

Or you can use the ActionName attribute as an alias

public ActionResult Submit(SearchCostPage model)
{
   ...
}

[ActionName("SubmitExcel")]
public ActionResult Submit(SearchCostPage model)
{
   ...
}

Do this :

$(document).ready(function(){
     $("#frm1").submit();
});

Re-Ordering data Table based on some condition or check box checked. PFB :-

 var tableResult= $('#exampleTable').DataTable();

    var $tr = $(this).closest('tr');
    if ($("#chkBoxId").prop("checked")) 
                    {
                        // re-draw table shorting based on condition
                        tableResult.row($tr).invalidate().order([colindx, 'asc']).draw();
                    }
                    else {
                        tableResult.row($tr).invalidate().order([colindx, "asc"]).draw();
                    }

You can also set a default value for the variable, so you don't need to use two "[", which amounts to two processes ("[" is actually a program) instead of one.

It goes by this syntax: ${VARIABLE:-default}.

The whole thing has to be thought in such a way that this "default" value is something distinct from a "valid" value/content.

If that's not possible for some reason you probably need to add a step like checking if there's a value at all, along the lines of "if [ -z $VARIABLE ] ; then echo "the variable needs to be filled"", or "if [ ! -z $VARIABLE ] ; then #everything is fine, proceed with the rest of the script".

This is more the the error itself, not answering the original question:

We were migrating from java 8 to java 11. Application compiled successfully, but the errors Unable to find a @SpringBootConfiguration started to appear in the integration tests when ran from command line using maven (from IntelliJ it worked).

It appeared that maven-failsafe-plugin stopped seeing the classes on classpath, we fixed that by telling failsafe plugin to include the classes manually:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-failsafe-plugin</artifactId>
            <configuration>
                <additionalClasspathElements>
                    <additionalClasspathElement>${basedir}/target/classes</additionalClasspathElement>
                </additionalClasspathElements>
            </configuration>
            ...
        </plugin>

Follow these steps (taken from this Youtube video).

1. Quit Skype
2. Uninstall IIS
   • Go to control panel
   • Refer to PROGRAMS AND FEATURES
   • Go to TURN WINDOWS FEATURES ON OR OFF
   • Look for INTERNET information service
   • Uninstall

This will only remove the tab, newlines, spaces and nothing else.

import re
myString = "I want to Remove all white \t spaces, new lines \n and tabs \t"
output   = re.sub(r"[\n\t\s]*", "", myString)

OUTPUT:

IwantoRemoveallwhiespaces,newlinesandtabs

Good day!

This look like a duplicate of JSTL conditional check.

The error is having the && outside the expression. Instead use

<c:if test="${ISAJAX == 0 && ISDATE == 0}">

For that last few years all of our projects have used NVARCHAR for everything, since all of these projects are multilingual. Imported data from external sources (e.g. an ASCII file, etc.) is up-converted to Unicode before being inserted into the database.

I've yet to encounter any performance-related issues from the larger indexes, etc. The indexes do use more memory, but memory is cheap.

Whether you use stored procedures or construct SQL on the fly ensure that all string constants are prefixed with N (e.g. SET @foo = N'Hello world.';) so the constant is also Unicode. This avoids any string type conversion at runtime.

YMMV.

My favourite minimalistic version based on Shubham Chaudhary answer.

Put this in build.gradle file:

test {
    afterSuite { desc, result ->
    if (!desc.parent)
        println("${result.resultType} " +
            "(${result.testCount} tests, " +
            "${result.successfulTestCount} successes, " +
            "${result.failedTestCount} failures, " +
            "${result.skippedTestCount} skipped)")
    }
}

Instead of writing it in your code directly I suggest you make use of the dedicated <connectionStrings> element in the .config file and retrieve it from there.

Also make use of the using statement so that after usage your connection automatically gets closed and disposed of.

A great reference for finding connection strings: connectionstrings.com/sql-server-2008.

Another solution

Here is a new solution based on Bennett McElwee answer in the same question as mentioned below.

Tested with IE 9 & 10, Opera 12.01, Google Chrome 22 and Firefox 15.0.
jsFiddle example

1.) Add this CSS to your site:

@media screen {
  #printSection {
      display: none;
  }
}

@media print {
  body * {
    visibility:hidden;
  }
  #printSection, #printSection * {
    visibility:visible;
  }
  #printSection {
    position:absolute;
    left:0;
    top:0;
  }
}

2.) Add my JavaScript function

function printElement(elem, append, delimiter) {
    var domClone = elem.cloneNode(true);

    var $printSection = document.getElementById("printSection");

    if (!$printSection) {
        $printSection = document.createElement("div");
        $printSection.id = "printSection";
        document.body.appendChild($printSection);
    }

    if (append !== true) {
        $printSection.innerHTML = "";
    }

    else if (append === true) {
        if (typeof (delimiter) === "string") {
            $printSection.innerHTML += delimiter;
        }
        else if (typeof (delimiter) === "object") {
            $printSection.appendChild(delimiter);
        }
    }

    $printSection.appendChild(domClone);
}?

You're ready to print any element on your site!
Just call printElement() with your element(s) and execute window.print() when you're finished.

Note: If you want to modify the content before it is printed (and only in the print version), checkout this example (provided by waspina in the comments): http://jsfiddle.net/95ezN/121/

One could also use CSS in order to show the additional content in the print version (and only there).

Former solution

I think, you have to hide all other parts of the site via CSS.

It would be the best, to move all non-printable content into a separate DIV:

<body>
  <div class="non-printable">
    <!-- ... -->
  </div>

  <div class="printable">
    <!-- Modal dialog comes here -->
  </div>
</body>

And then in your CSS:

.printable { display: none; }

@media print
{
    .non-printable { display: none; }
    .printable { display: block; }
}

Credits go to Greg who has already answered a similar question: Print <div id="printarea"></div> only?

There is one problem in using JavaScript: the user cannot see a preview - at least in Internet Explorer!

$CI =& get_instance();

if($CI->input->get('id'){
    $id = $CI->input->get('id');

}

bs := string(body) should be enough to give you a string.

From there, you can use it as a regular string.

A bit as in this thread:

var client http.Client
resp, err := client.Get(url)
if err != nil {
    log.Fatal(err)
}
defer resp.Body.Close()

if resp.StatusCode == http.StatusOK {
    bodyBytes, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        log.Fatal(err)
    }
    bodyString := string(bodyBytes)
    log.Info(bodyString)
}

See also GoByExample.

As commented below (and in zzn's answer), this is a conversion (see spec).
See "How expensive is []byte(string)?" (reverse problem, but the same conclusion apply) where zzzz mentioned:

Some conversions are the same as a cast, like uint(myIntvar), which just reinterprets the bits in place.

Sonia adds:

Making a string out of a byte slice, definitely involves allocating the string on the heap. The immutability property forces this.
Sometimes you can optimize by doing as much work as possible with []byte and then creating a string at the end. The bytes.Buffer type is often useful.

In my use case, I parameterized some fields in an HTML document, and once I load these fields I match and replace them using the str_replace method.

<?php echo str_replace(array("{{client_name}}", "{{client_testing}}"), array('client_company_name', 'test'), 'html_document'); ?>

If you want to return a boolean value, then you can use something like this (much faster than filter):

players.stream().anyMatch(player -> player.getName().contains(name));

You'll want to do get a Calendar instance and get it's day of month

Calendar cal = Calendar.getInstance();
int dayOfMonth = cal.get(Calendar.DAY_OF_MONTH);

String dayOfMonthStr = String.valueOf(dayOfMonth);

You can also get DAY_OF_WEEK, DAY_OF_YEAR, DAY_OF_WEEK_IN_MONTH, etc.

As the compiler says, grid was not declared in the scope of your function :) "Scope" basically means a set of curly braces. Every variable is limited to the scope in which it is declared (it cannot be accessed outside that scope). In your case, you're declaring the grid variable in your main() function and trying to use it in nonrecursivecountcells(). You seem to be passing it as the argument colors however, so I suggest you just rename your uses of grid in nonrecursivecountcells() to colors. I think there may be something wrong with trying to pass the array that way, too, so you should probably investigate passing it as a pointer (unless someone else says something to the contrary).

By CSS:

.disable{
   cursor: not-allowed;
   pointer-events: none;
}

Them you can add any decoration to that button. For change the status you can use jquery

$("#id").toggleClass('disable');

There is an interesting difference between the two popular solutions above:

1. If you create the bare repository like this:

   cd     /outside_of_any_repo
   mkdir  my_remote.git
   cd     my_remote.git
   git init --bare
   

and then

cd  /your_path/original_repo
git remote add origin /outside_of_any_repo/my_remote.git
git push --set-upstream origin master

Then git sets up the configuration in 'original_repo' with this relationship:

original_repo origin --> /outside_of_any_repo/my_remote.git/

with the latter as the upstream remote. And the upstream remote doesn't have any other remotes in its configuration.

2. However, if you do it the other way around:

   (from in directory original_repo)
   cd ..
   git clone --bare original_repo  /outside_of_any_repo/my_remote.git
   

then 'my_remote.git' winds up with its configuration having 'origin' pointing back to 'original_repo' as a remote, with a remote.origin.url equating to local directory path, which might not be appropriate if it is going to be moved to a server.

While that "remote" reference is easy to get rid of later if it isn't appropriate, 'original_repo' still has to be set up to point to 'my_remote.git' as an up-stream remote (or to wherever it is going to be shared from). So technically, you can arrive at the same result with a few more steps with approach #2. But #1 seems a more direct approach to creating a "central bare shared repo" originating from a local one, appropriate for moving to a server, with fewer steps involved. I think it depends on the role you want the remote repo to play. (And yes, this is in conflict with the documentation here.)

Caveat: I learned the above (at this writing in early August 2019) by doing a test on my local system with a real repo, and then doing a file-by-file comparison between the results. But! I am still learning, so there could be a more correct way. But my tests have helped me conclude that #1 is my currently-preferred method.

I have used Open source Web Design in the past. They have quite a few css themes, don't know about ASP.Net

Here's an alternative way, that does not involve any "hacks", but requires ASP.NET 4.0 or later:

//Global.asax
private void Application_Error(object sender, EventArgs e)
{
    var ex = Server.GetLastError();
    var httpException = ex as HttpException ?? ex.InnerException as HttpException;
    if(httpException == null) return;

    if(httpException.WebEventCode == WebEventCodes.RuntimeErrorPostTooLarge)
    {
        //handle the error
        Response.Write("Sorry, file is too big"); //show this message for instance
    }
}

The "normal" way is to:

• Go to the Beautiful Soup web site, http://www.crummy.com/software/BeautifulSoup/
• Download the package
• Unpack it
• In a Terminal window, cd to the resulting directory
• Type python setup.py install

Another solution is to use easy_install. Go to http://peak.telecommunity.com/DevCenter/EasyInstall), install the package using the instructions on that page, and then type, in a Terminal window:

easy_install BeautifulSoup4
# for older v3:
# easy_install BeautifulSoup

easy_install will take care of downloading, unpacking, building, and installing the package. The advantage to using easy_install is that it knows how to search for many different Python packages, because it queries the PyPI registry. Thus, once you have easy_install on your machine, you install many, many different third-party packages simply by one command at a shell.

Check if you are importing the same packages in your .m and in your .h Example given: I had this very problem with the init method and it was caused by missing the "#import " on the .m file

a = "a=b,c:d"

array = ['=',',',':'];

for(i=0; i< array.length; i++){ a= a.split(array[i]).join(); }

this will return the string without a special charecter.

Teylyn's answer worked great for me, but I had to modify it a bit to get proper results. I want to provide an extended explanation for whoever would need it.

My setup was as follows:

• Sheet1: full data of 2014
• Sheet2: updated rows for 2015 in A1:D50, sorted by first column
• Sheet3: merged rows
• My data does not have a header row

I put the following formula in cell A1 of Sheet3:

=iferror(vlookup(Sheet1!A$1;Sheet2!$A$1:$D$50;column(A1);false);Sheet1!A1)

Read this as follows: Take the value of the first column in Sheet1 (old data). Look up in Sheet2 (updated rows). If present, output the value from the indicated column in Sheet2. On error, output the value for the current column of Sheet1.

Notes:

• In my version of the formula, ";" is used as parameter separator instead of ",". That is because I am located in Europe and we use the "," as decimal separator. Change ";" back to "," if you live in a country where "." is the decimal separator.

• A$1: means always take column 1 when copying the formula to a cell in a different column. $A$1 means: always take the exact cell A1, even when copying the formula to a different row or column.

After pasting the formula in A1, I extended the range to columns B, C, etc., until the full width of my table was reached. Because of the $-signs used, this gives the following formula's in cells B1, C1, etc.:

=IFERROR(VLOOKUP('Sheet1'!$A1;'Sheet2'!$A$1:$D$50;COLUMN(B1);FALSE);'Sheet1'!B1)
=IFERROR(VLOOKUP('Sheet1'!$A1;'Sheet2'!$A$1:$D$50;COLUMN(C1);FALSE);'Sheet1'!C1)

and so forth. Note that the lookup is still done in the first column. This is because VLOOKUP needs the lookup data to be sorted on the column where the lookup is done. The output column is however the column where the formula is pasted.

Next, select a rectangle in Sheet 3 starting at A1 and having the size of the data in Sheet1 (same number of rows and columns). Press Ctrl-D to copy the formulas of the first row to all selected cells.

Cells A2, A3, etc. will get these formulas:

=IFERROR(VLOOKUP('Sheet1'!$A2;'Sheet2'!$A$1:$D$50;COLUMN(A2);FALSE);'Sheet1'!A2)
=IFERROR(VLOOKUP('Sheet1'!$A3;'Sheet2'!$A$1:$D$50;COLUMN(A3);FALSE);'Sheet1'!A3)

Because of the use of $-signs, the lookup area is constant, but input data is used from the current row.

For me, I had to remove

<item name="android:gravity">center_vertical</item>

from RelativeLayout, so children's configuration would work:

<item name="android:layout_centerVertical">true</item>

This is another C example of where the same syntax has different meanings (in different places). While one might be able to argue that the syntax should be different for these two cases, it is what it is. The idea is that not that it is "not allowed" but that the second thing means something different (it means "pointer assignment").

I have seen many answers to this question and found some answer is lengthy and some answer is a little bit wrong. I have created my own code by using the above IDs and class.

$('#ckbCheckAll').click(function(){
        if($(this).prop("checked")) {
            $(".checkBoxClass").prop("checked", true);
        } else {
            $(".checkBoxClass").prop("checked", false);
        }                
    });


    $('.checkBoxClass').click(function(){
        if($(".checkBoxClass").length == $(".checkBoxClass:checked").length) { 
            $("#ckbCheckAll").prop("checked", true);
        }else {
            $("#ckbCheckAll").prop("checked", false);            
        }
    });

In the above code, where user clicks on select all checkbox and all checkbox will be selected and vice versa and second code will work when the user selects checkbox one by one then select all checkbox will be checked or unchecked according to a number of checkboxes checked.

For random hash values, some engineers said golden ratio prime number(2654435761) is a bad choice, with my testing results, I found that it's not true; instead, 2654435761 distributes the hash values pretty good.

#define MCR_HashTableSize 2^10

unsigned int
Hash_UInt_GRPrimeNumber(unsigned int key)
{
  key = key*2654435761 & (MCR_HashTableSize - 1)
  return key;
}

The hash table size must be a power of two.

I have written a test program to evaluate many hash functions for integers, the results show that GRPrimeNumber is a pretty good choice.

I have tried:

1. total_data_entry_number / total_bucket_number = 2, 3, 4; where total_bucket_number = hash table size;
2. map hash value domain into bucket index domain; that is, convert hash value into bucket index by Logical And Operation with (hash_table_size - 1), as shown in Hash_UInt_GRPrimeNumber();
3. calculate the collision number of each bucket;
4. record the bucket that has not been mapped, that is, an empty bucket;
5. find out the max collision number of all buckets; that is, the longest chain length;

With my testing results, I found that Golden Ratio Prime Number always has the fewer empty buckets or zero empty bucket and the shortest collision chain length.

Some hash functions for integers are claimed to be good, but the testing results show that when the total_data_entry / total_bucket_number = 3, the longest chain length is bigger than 10(max collision number > 10), and many buckets are not mapped(empty buckets), which is very bad, compared with the result of zero empty bucket and longest chain length 3 by Golden Ratio Prime Number Hashing.

BTW, with my testing results, I found one version of shifting-xor hash functions is pretty good(It's shared by mikera).

unsigned int Hash_UInt_M3(unsigned int key)
{
  key ^= (key << 13);
  key ^= (key >> 17);    
  key ^= (key << 5); 
  return key;
}

You'll want to use the GetExtensionName method on the FileSystemObject object.

Set x = CreateObject("scripting.filesystemobject")
WScript.Echo x.GetExtensionName("foo.pdf")

In your example, try using this

For Each objFile in colFiles
    If UCase(objFSO.GetExtensionName(objFile.name)) = "PDF" Then
        Wscript.Echo objFile.Name
    End If

When you $ pip install jupyter several dependencies are installed. The best way to uninstall it completely is by running:

1. $ pip install pip-autoremove
2. $ pip-autoremove jupyter -y

Kindly refer to this related question.

pip-autoremove removes a package and its unused dependencies. Here are the docs.

There is not a way to directly get the version out, but there are two work-arounds that could be done.

1. The version could be stored in a resource string, and placed into the manifest by:

   <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.somepackage"
        android:versionName="@string/version" android:versionCode="20">
   

2. One could create a custom view, and place it into the XML. The view would use this to assign the name:

   context.getPackageManager().getPackageInfo(context.getPackageName(), 0).versionName;
   

Either of these solutions would allow for placing the version name in XML. Unfortunately there isn't a nice simple solution, like android.R.string.version or something like that.

In Python, you simply cannot kill a Thread directly.

If you do NOT really need to have a Thread (!), what you can do, instead of using the threading package , is to use the multiprocessing package . Here, to kill a process, you can simply call the method:

yourProcess.terminate()  # kill the process!

Python will kill your process (on Unix through the SIGTERM signal, while on Windows through the TerminateProcess() call). Pay attention to use it while using a Queue or a Pipe! (it may corrupt the data in the Queue/Pipe)

Note that the multiprocessing.Event and the multiprocessing.Semaphore work exactly in the same way of the threading.Event and the threading.Semaphore respectively. In fact, the first ones are clones of the latters.

If you REALLY need to use a Thread, there is no way to kill it directly. What you can do, however, is to use a "daemon thread". In fact, in Python, a Thread can be flagged as daemon:

yourThread.daemon = True  # set the Thread as a "daemon thread"

The main program will exit when no alive non-daemon threads are left. In other words, when your main thread (which is, of course, a non-daemon thread) will finish its operations, the program will exit even if there are still some daemon threads working.

Note that it is necessary to set a Thread as daemon before the start() method is called!

Of course you can, and should, use daemon even with multiprocessing. Here, when the main process exits, it attempts to terminate all of its daemonic child processes.

Finally, please, note that sys.exit() and os.kill() are not choices.

/*
 * jQuery Highlight plugin
 *
 * Based on highlight v3 by Johann Burkard
 * http://johannburkard.de/blog/programming/javascript/highlight-javascript-text-higlighting-jquery-plugin.html
 *
 * Code a little bit refactored and cleaned (in my humble opinion).
 * Most important changes:
 *  - has an option to highlight only entire words (wordsOnly - false by default),
 *  - has an option to be case sensitive (caseSensitive - false by default)
 *  - highlight element tag and class names can be specified in options
 *
 * Usage:
 *   // wrap every occurrance of text 'lorem' in content
 *   // with <span class='highlight'> (default options)
 *   $('#content').highlight('lorem');
 *
 *   // search for and highlight more terms at once
 *   // so you can save some time on traversing DOM
 *   $('#content').highlight(['lorem', 'ipsum']);
 *   $('#content').highlight('lorem ipsum');
 *
 *   // search only for entire word 'lorem'
 *   $('#content').highlight('lorem', { wordsOnly: true });
 *
 *   // don't ignore case during search of term 'lorem'
 *   $('#content').highlight('lorem', { caseSensitive: true });
 *
 *   // wrap every occurrance of term 'ipsum' in content
 *   // with <em class='important'>
 *   $('#content').highlight('ipsum', { element: 'em', className: 'important' });
 *
 *   // remove default highlight
 *   $('#content').unhighlight();
 *
 *   // remove custom highlight
 *   $('#content').unhighlight({ element: 'em', className: 'important' });

Pyflakes does what you ask, it just checks the syntax. From the docs:

Pyflakes makes a simple promise: it will never complain about style, and it will try very, very hard to never emit false positives.

Pyflakes is also faster than Pylint or Pychecker. This is largely because Pyflakes only examines the syntax tree of each file individually.

To install and use:

$ pip install pyflakes
$ pyflakes yourPyFile.py

In addition to reg.exe, I highly recommend that you also check out powershell, its vastly more capable in its registry handling.

Your k^th FFT result's frequency is 2*pi*k/N.

Also can be done from the environment variable:

Actually you can capture Query strings in MVC in two ways.....

public ActionResult CrazyMVC(string knownQuerystring)
{

  // This is the known query string captured by the Controller Action Method parameter above
  string myKnownQuerystring = knownQuerystring;

  // This is what I call the mysterious "unknown" query string
  // It is not known because the Controller isn't capturing it
  string myUnknownQuerystring = Request.QueryString["unknownQuerystring"];

  return Content(myKnownQuerystring + " - " + myUnknownQuerystring);

}

This would capture both query strings...for example:

/CrazyMVC?knownQuerystring=123&unknownQuerystring=456

Output: 123 - 456

Don't ask me why they designed it that way. Would make more sense if they threw out the whole Controller action system for individual query strings and just returned a captured dynamic list of all strings/encoded file objects for the URL by url-form-encoding so you can easily access them all in one call. Maybe someone here can demonstrate that if its possible?

Makes no sense to me how Controllers capture query strings, but it does mean you have more flexibility to capture query strings than they teach you out of the box. So pick your poison....both work fine.

I had the same problem. This what worked for me:

1. Go to SQL Server Management Studio and run it as Administrator.
2. Choose Security -> Then Logins
3. Choose the usernames or whatever users that will access your database under the Logins and Double Click it.
4. Give them a Server Roles that will give them credentials to create database. On my case, public was already checked so I checked dbcreator and sysadmin.
5. Run update-database again on Package Manager Console. Database should now successfully created.

Here is an image so that you can get the bigger picture, I blurred my credentials of course:

res is an HttpResponse object which extends from OutgoingMessage. res.send calls res.end which is implemented by OutgoingMessage to send HTTP response and close connection. We see code here

In psql that would be

No this is not the definition of scrum, it is the wikipedia excerpt on the definition of burnout.

Dont do too many short 10 days sprints. You will burnout your team eventually. Use short sprints where you really need them, and don't do too many in a row. Think long-term. A distance runner always paces themselves for the full race and does sprints in short distances only where it matters.

If you burnout your team you can toss out all them fancy scrum charts, they won't do a thing for your team's plummeting productivity.

@Repository
public interface ExpenseRepo extends JpaRepository<Expense,Long> {
    List<Expense> findByCategoryId(Long categoryId);

    @Query(value = "select category.name,SUM(expense.amount) from expense JOIN category ON expense.category_id=category.id GROUP BY expense.category_id",nativeQuery = true)
    List<?> getAmountByCategory();

}

The above code worked for me.

I've also had this happen (by accident) after creating a new venv while inside an existing virtual environment. an easy way to diagnose this would be to see where the python is symlinked to, i.e. run:

ls -l venv/bin/python

and make sure it points to the appropriate Python binary. For most systems this will be /usr/bin/python or /usr/bin/python3. while if it points to an existing virtual environment it'll be something like /home/youruser/somedir/bin/python. if it's the latter than I'd suggest recreating the venv while making sure that you aren't "inside" any existing virtualenv (i.e. run deactivate )

UEFA internally provides their own LIVEX Api for their Broadcasting Partners. That one is perfect enough to develop the Applications by their partners for themselves.

simple we are going to wait for 5 seconds for some event to happen (that would be indicated by done variable set to true somewhere else in the code) or when timeout expires that we will check every 100ms

    var timeout=5000; //will wait for 5 seconds or untildone
    var scope = this; //bind this to scope variable
    (function() {
        if (timeout<=0 || scope.done) //timeout expired or done
        {
            scope.callback();//some function to call after we are done
        }
        else
        {
            setTimeout(arguments.callee,100) //call itself again until done
            timeout -= 100;
        }
    })();

I know this was asked awhile back, but I found a comprehensive list of the virtual keyboard key codes right in MSDN, for use in C/C++. This also includes the mouse events. Note it is different than the javascript key codes (I noticed it around the VK_OEM section).

Here's the link:

As of Python3 you no longer need to open devnull and can call subprocess.DEVNULL.

Your code would be updated as such:

import subprocess
text = 'Hello World.'
print(text)
subprocess.call(['espeak', text], stderr=subprocess.DEVNULL)

The problem is the std namespace you are missing. cout is in the std namespace.
Add using namespace std; after the #include

data = "abcdefg hi j 12345"

digits_count = 0
letters_count = 0
others_count = 0

for i in userinput:

    if i.isdigit():
        digits_count += 1 
    elif i.isalpha():
        letters_count += 1
    else:
        others_count += 1

print("Result:")        
print("Letters=", letters_count)
print("Digits=", digits_count)

Output:

Please Enter Letters with Numbers:
abcdefg hi j 12345
Result:
Letters = 10
Digits = 5

By using str.isalpha() you can check if it is a letter.

A full example ?. Run this code : (NB: This example is best run in the console and not from within an IDE, since the System.console() method might return null in that case.)

import java.io.Console;
public class Main {

    public void passwordExample() {        
        Console console = System.console();
        if (console == null) {
            System.out.println("Couldn't get Console instance");
            System.exit(0);
        }

        console.printf("Testing password%n");
        char[] passwordArray = console.readPassword("Enter your secret password: ");
        console.printf("Password entered was: %s%n", new String(passwordArray));

    }

    public static void main(String[] args) {
        new Main().passwordExample();
    }
}

ICU4J contains nice number-spellout support. The files with the "rules" can be easily edited, and it's no problem to add other languages (we did it e.g. for Polish and Russian).

For safety (buffer overflow) I recommend to use snprintf()

const int MAX_BUF = 1000;
char* Buffer = malloc(MAX_BUF);

int length = 0;
length += snprintf(Buffer+length, MAX_BUF-length, "Hello World");
length += snprintf(Buffer+length, MAX_BUF-length, "Good Morning");
length += snprintf(Buffer+length, MAX_BUF-length, "Good Afternoon");

For C++ :

I just faced the same issue and I think it is worth mentioning a problem comes up when one use both __stdcall (or WINAPI) and extern "C":

As you know extern "C" removes the decoration so that instead of :

__declspec(dllexport) int Test(void)                        --> dumpbin : ?Test@@YaHXZ

you obtain a symbol name undecorated:

extern "C" __declspec(dllexport) int Test(void)             --> dumpbin : Test

However the _stdcall ( = macro WINAPI, that changes the calling convention) also decorates names so that if we use both we obtain :

   extern "C" __declspec(dllexport) int WINAPI Test(void)   --> dumpbin : _Test@0

and the benefit of extern "C" is lost because the symbol is decorated (with _ @bytes)

Note that this only occurs for x86 architecture because the __stdcall convention is ignored on x64 (msdn : on x64 architectures, by convention, arguments are passed in registers when possible, and subsequent arguments are passed on the stack.).

This is particularly tricky if you are targeting both x86 and x64 platforms.

Two solutions

1. Use a definition file. But this forces you to maintain the state of the def file.

2. the simplest way : define the macro (see msdn) :

#define EXPORT comment(linker, "/EXPORT:" __FUNCTION__ "=" __FUNCDNAME__)

and then include the following pragma in the function body:

#pragma EXPORT

Full Example :

 int WINAPI Test(void)
{
    #pragma EXPORT
    return 1;
}

This will export the function undecorated for both x86 and x64 targets while preserving the __stdcall convention for x86. The __declspec(dllexport) is not required in this case.

This is how I solved

   <a href="#" >
      <button type="button" class="btn btn-info">Button Text</button>
   </a>  

I don't think there is, but you can do something like this:

enum choices {a1, a2, b1, b2};

public static boolean exists(choices choice) {
   for(choice aChoice : choices.values()) {
      if(aChoice == choice) {
         return true;
      }
   }
   return false;
}

Edit:

Please see Richard's version of this as it is more appropriate as this won't work unless you convert it to use Strings, which Richards does.

function change() {
 myButton1.value=="Open Curtain" ? myButton1.value="Close Curtain" : myButton1.value="Open Curtain";
}

I consider Ashwin's answer to be the most correct, my old answer is below.

docker run -dti foo bash

You can then enter the container and run bash with

docker exec -ti ID_of_foo bash

No need to install sshd :)

I thought it would be interesting to point out which methods are the quickest, and in what scenario:

Here's some tests I ran (on a 2012 MacBook Pro)

>>> def method1(list,search_age):
...     for name,age in list.iteritems():
...             if age == search_age:
...                     return name
... 
>>> def method2(list,search_age):
...     return [name for name,age in list.iteritems() if age == search_age]
... 
>>> def method3(list,search_age):
...     return list.keys()[list.values().index(search_age)]

Results from profile.run() on each method 100000 times:

Method 1:

>>> profile.run("for i in range(0,100000): method1(list,16)")
     200004 function calls in 1.173 seconds

Method 2:

>>> profile.run("for i in range(0,100000): method2(list,16)")
     200004 function calls in 1.222 seconds

Method 3:

>>> profile.run("for i in range(0,100000): method3(list,16)")
     400004 function calls in 2.125 seconds

So this shows that for a small dict, method 1 is the quickest. This is most likely because it returns the first match, as opposed to all of the matches like method 2 (see note below).

Interestingly, performing the same tests on a dict I have with 2700 entries, I get quite different results (this time run 10000 times):

Method 1:

>>> profile.run("for i in range(0,10000): method1(UIC_CRS,'7088380')")
     20004 function calls in 2.928 seconds

Method 2:

>>> profile.run("for i in range(0,10000): method2(UIC_CRS,'7088380')")
     20004 function calls in 3.872 seconds

Method 3:

>>> profile.run("for i in range(0,10000): method3(UIC_CRS,'7088380')")
     40004 function calls in 1.176 seconds

So here, method 3 is much faster. Just goes to show the size of your dict will affect which method you choose.

Notes: Method 2 returns a list of all names, whereas methods 1 and 3 return only the first match. I have not considered memory usage. I'm not sure if method 3 creates 2 extra lists (keys() and values()) and stores them in memory.

In ASP.NET MVC 3 Preview1 you can import a namespace on all your razor views with this code in Global.asax.cs

Microsoft.WebPages.Compilation.CodeGeneratorSettings.AddGlobalImport("Namespace.Namespace");

I hope in RTM this gets done through Web.config section.

I would suggest learning about position: relative and child elements with position: absolute.

Sorry, didn't quite get your question. So something like this?

str.ToCharArray().Any(char.IsDigit);

Or does the value have to be an integer completely, without any additional strings?

if(str.ToCharArray().All(char.IsDigit(c));

sed -i "" -e $'4 a\\n''Project_Name=sowstest' start

I found JXDatePicker as a better solution to this. It gives what you need and very easy to use.

import java.text.SimpleDateFormat;
import java.util.Calendar;
import javax.swing.JFrame;
import javax.swing.JPanel;
import org.jdesktop.swingx.JXDatePicker;

public class DatePickerExample extends JPanel {

    public static void main(String[] args) {
        JFrame frame = new JFrame("JXPicker Example");
        JPanel panel = new JPanel();

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setBounds(400, 400, 250, 100);

        JXDatePicker picker = new JXDatePicker();
        picker.setDate(Calendar.getInstance().getTime());
        picker.setFormats(new SimpleDateFormat("dd.MM.yyyy"));

        panel.add(picker);
        frame.getContentPane().add(panel);

        frame.setVisible(true);
    }
}

I would just like to add that Step.js library helps you handle exceptions by always passing it to the next step function. Therefore you can have as a last step a function that check for any errors in any of the previous steps. This approach can greatly simplify your error handling.

Below is a quote from the github page:

any exceptions thrown are caught and passed as the first argument to the next function. As long as you don't nest callback functions inline your main functions this prevents there from ever being any uncaught exceptions. This is very important for long running node.JS servers since a single uncaught exception can bring the whole server down.

Furthermore, you can use Step to control execution of scripts to have a clean up section as the last step. For example if you want to write a build script in Node and report how long it took to write, the last step can do that (rather than trying to dig out the last callback).

list = [1,1,1,0]
print(any(list)) # will return True because there is  1 or True exists
print(all(list)) # will return False because there is a 0 or False exists
return all(a % i for i in range(3, int(a ** 0.5) + 1)) # when number is divisible it will return False else return True but the whole statement is False .

Just perform a list comprehension to create your columns:

In [28]:

filter_col = [col for col in df if col.startswith('foo')]
filter_col
Out[28]:
['foo.aa', 'foo.bars', 'foo.fighters', 'foo.fox', 'foo.manchu']
In [29]:

df[filter_col]
Out[29]:
   foo.aa  foo.bars  foo.fighters  foo.fox foo.manchu
0     1.0         0             0        2         NA
1     2.1         0             1        4          0
2     NaN         0           NaN        1          0
3     4.7         0             0        0          0
4     5.6         0             0        0          0
5     6.8         1             0        5          0

Another method is to create a series from the columns and use the vectorised str method startswith:

In [33]:

df[df.columns[pd.Series(df.columns).str.startswith('foo')]]
Out[33]:

In order to achieve what you want you need to add the following to filter the values that don't meet your ==1 criteria:

In [36]:

df[df[df.columns[pd.Series(df.columns).str.startswith('foo')]]==1]
Out[36]:
   bar.baz  foo.aa  foo.bars  foo.fighters  foo.fox foo.manchu nas.foo
0      NaN       1       NaN           NaN      NaN        NaN     NaN
1      NaN     NaN       NaN             1      NaN        NaN     NaN
2      NaN     NaN       NaN           NaN        1        NaN     NaN
3      NaN     NaN       NaN           NaN      NaN        NaN     NaN
4      NaN     NaN       NaN           NaN      NaN        NaN     NaN
5      NaN     NaN         1           NaN      NaN        NaN     NaN

EDIT

OK after seeing what you want the convoluted answer is this:

In [72]:

df.loc[df[df[df.columns[pd.Series(df.columns).str.startswith('foo')]] == 1].dropna(how='all', axis=0).index]
Out[72]:
   bar.baz  foo.aa  foo.bars  foo.fighters  foo.fox foo.manchu nas.foo
0      5.0     1.0         0             0        2         NA      NA
1      5.0     2.1         0             1        4          0       0
2      6.0     NaN         0           NaN        1          0       1
5      6.8     6.8         1             0        5          0       0

Try (maybe as root)

lsof -i -P

and grep the output for the port you are looking for.

For example to check for port 80 do

lsof -i -P | grep :80

Aggregation of all postgres sessions per their status (how many are idle, how many doing something...)

select state, count(*) from pg_stat_activity  where pid <> pg_backend_pid() group by 1 order by 1;

$('.input').keypress(function (e) {
  if (e.which == 13) {
    $('form#login').submit();
    return false;    //<---- Add this line
  }
});

Check out this stackoverflow answer: event.preventDefault() vs. return false

Essentially, "return false" is the same as calling e.preventDefault and e.stopPropagation().

Yes it is, there have to be boolean expresion after IF. Here you have a direct link. I hope it helps. GL!

You can achieve this by two methods

1. Using XML
2. Using java

Using XML Add this attribute to toolbar XML app:menu = "menu_name"

Using java By overriding onCreateOptionMenu(Menu menu)

public class MainActivity extends AppCompatActivity { 

  private Toolbar toolbar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        toolbar = findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
}
@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.demo_menu,menu);
        return super.onCreateOptionsMenu(menu);
    }
}

for more details or implementating click on the menu go through this article https://bedevelopers.tech/android-toolbar-implementation-using-android-studio/

How about having an angel with a flaming sword?

1. Might sound naive, and I dunno what your application does actually, but what about the extensive use of includes?

2. For the legitimate user, is all the software that should be visible or only parts of it? Because you could obfuscate and give a copy of source code to legitimate

3. You could wrap the php in a container like Phalanger (.NET)

4. Perhaps your concerned with external theft, meaning your code freely visible over the web as customers uses it. This could be worth investing in a cheap web site hosting, for $50 a year, registering your legit customers with a serial in their code and have your app posting info to your web site regularly. At least, you'd detect when code has been compromised. You could push it with a self destruct after n days, giving you enough time to contact your customer and change the serial. This could be the only obfuscated include() of the whole code

There are different ways to measure the height depending on what you need.

getTextBounds

If you are doing something like precisely centering a small amount of fixed text, you probably want getTextBounds. You can get the bounding rectangle like this

Rect bounds = new Rect();
mTextPaint.getTextBounds(mText, 0, mText.length(), bounds);
int height = bounds.height();

As you can see for the following images, different strings will give different heights (shown in red).

These differing heights could be a disadvantage in some situations when you just need a constant height no matter what the text is. See the next section.

Paint.FontMetrics

You can calculate the hight of the font from the font metrics. The height is always the same because it is obtained from the font, not any particular text string.

Paint.FontMetrics fm = mTextPaint.getFontMetrics();
float height = fm.descent - fm.ascent;

The baseline is the line that the text sits on. The descent is generally the furthest a character will go below the line and the ascent is generally the furthest a character will go above the line. To get the height you have to subtract ascent because it is a negative value. (The baseline is y=0 and y descreases up the screen.)

Look at the following image. The heights for both of the strings are 234.375.

If you want the line height rather than just the text height, you could do the following:

float height = fm.bottom - fm.top + fm.leading; // 265.4297

These are the bottom and top of the line. The leading (interline spacing) is usually zero, but you should add it anyway.

The images above come from this project. You can play around with it to see how Font Metrics work.

StaticLayout

For measuring the height of multi-line text you should use a StaticLayout. I talked about it in some detail in this answer, but the basic way to get this height is like this:

String text = "This is some text. This is some text. This is some text. This is some text. This is some text. This is some text.";

TextPaint myTextPaint = new TextPaint();
myTextPaint.setAntiAlias(true);
myTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
myTextPaint.setColor(0xFF000000);

int width = 200;
Layout.Alignment alignment = Layout.Alignment.ALIGN_NORMAL;
float spacingMultiplier = 1;
float spacingAddition = 0;
boolean includePadding = false;

StaticLayout myStaticLayout = new StaticLayout(text, myTextPaint, width, alignment, spacingMultiplier, spacingAddition, includePadding);

float height = myStaticLayout.getHeight(); 

create table myTable 
(
    Column1 int not null,
    Column2 int not null
)
GO


ALTER TABLE myTable
    ADD  PRIMARY KEY (Column1,Column2)
GO

Use CHARINDEX to find the ";". Then use SUBSTRING to just return the part before the ";".

I set the PHPRC variable and uncommented zend_extension=php_opcache.dll in php.ini and all works well.

Add your image path like fullPathname='assets/images/therealdealportfoliohero.jpg' in your constructor. It will work definitely.

Linux

If you're using Linux and .NET Core, see this question, you'll want to use

dotnet add package Newtonsoft.Json

And then add

using Newtonsoft.Json;

to any classes needing that.

same problem for me, original code from spring starter demo gives unknown error on line 1:

Changing just the version of 2.1.6.RELEASE to 2.1.4.RELEASE fixes the problem.

Gaa! Go to asciitable.com. The arrow keys are the control equivalent of the HJKL keys. I.e., in vi create a big block of text. Note you can move around in that text using the HJKL keys. The arrow keys are going to be ^H, ^J, ^K, ^L.

At asciitable.com find, "K" in the third column. Now, look at the same row in the first column to find the matching control-code ("VT" in this case).

ArrayList<String> resultList = new ArrayList<String>();
resultList.addAll(arrayList1);
resultList.addAll(arrayList2);

• I always use copy con to write text, It so easy to write a long text

• Example:

  C:\COPY CON [drive:][path][File name]

I like to use the following to get a nicely sorted listing of the current dir:

> dir . /s /b sortorder:N

There is collection of Func<...> classes - Func that is probably what you are looking for:

 void MyMethod(Func<int> param1 = null) 

This defines method that have parameter param1 with default value null (similar to AS), and a function that returns int. Unlike AS in C# you need to specify type of the function's arguments.

So if you AS usage was

MyMethod(function(intArg, stringArg) { return true; }) 

Than in C# it would require param1 to be of type Func<int, siring, bool> and usage like

MyMethod( (intArg, stringArg) => { return true;} ); 

If you really want to split every word (bash meaning) into a different array index completely changing the array in every while loop iteration, @ruakh's answer is the correct approach. But you can use the read property to split every read word into different variables column1, column2, column3 like in this code snippet

while IFS=$'\t' read -r column1 column2 column3 ; do
  printf "%b\n" "column1<${column1}>"
  printf "%b\n" "column2<${column2}>"
  printf "%b\n" "column3<${column3}>"
done < "myfile"

to reach a similar result avoiding array index access and improving your code readability by using meaningful variable names (of course using columnN is not a good idea to do so).

To get the value of a pointer, just de-reference the pointer.

int *ptr;
int value;
*ptr = 9;

value = *ptr;

value is now 9.

I suggest you read more about pointers, this is their base functionality.

The answers above check if a filesystem contains a path that is a file or directory. But it doesn't identify if a given path alone is a file or directory.

The answer is to identify directory-based paths using "/." like --> "/c/dos/run/." <-- trailing period.

Like a path of a directory or file that has not been written yet. Or a path from a different computer. Or a path where both a file and directory of the same name exists.

// /tmp/
// |- dozen.path
// |- dozen.path/.
//    |- eggs.txt
//
// "/tmp/dozen.path" !== "/tmp/dozen.path/"
//
// Very few fs allow this. But still. Don't trust the filesystem alone!

// Converts the non-standard "path-ends-in-slash" to the standard "path-is-identified-by current "." or previous ".." directory symbol.
function tryGetPath(pathItem) {
    const isPosix = pathItem.includes("/");
    if ((isPosix && pathItem.endsWith("/")) ||
        (!isPosix && pathItem.endsWith("\\"))) {
        pathItem = pathItem + ".";
    }
    return pathItem;
}
// If a path ends with a current directory identifier, it is a path! /c/dos/run/. and c:\dos\run\.
function isDirectory(pathItem) {
    const isPosix = pathItem.includes("/");
    if (pathItem === "." || pathItem ==- "..") {
        pathItem = (isPosix ? "./" : ".\\") + pathItem;
    }
    return (isPosix ? pathItem.endsWith("/.") || pathItem.endsWith("/..") : pathItem.endsWith("\\.") || pathItem.endsWith("\\.."));
} 
// If a path is not a directory, and it isn't empty, it must be a file
function isFile(pathItem) {
    if (pathItem === "") {
        return false;
    }
    return !isDirectory(pathItem);
}

Last thought: Why even hit the filesystem?

You can't wait() on an object unless the current thread owns that object's monitor. To do that, you must synchronize on it:

class Runner implements Runnable
{
  public void run()
  {
    try
    {
      synchronized(Main.main) {
        Main.main.wait();
      }
    } catch (InterruptedException e) {}
    System.out.println("Runner away!");
  }
}

The same rule applies to notify()/notifyAll() as well.

The Javadocs for wait() mention this:

This method should only be called by a thread that is the owner of this object's monitor. See the notify method for a description of the ways in which a thread can become the owner of a monitor.

Throws:

IllegalMonitorStateException – if the current thread is not the owner of this object's monitor.

And from notify():

A thread becomes the owner of the object's monitor in one of three ways:

• By executing a synchronized instance method of that object.
• By executing the body of a synchronized statement that synchronizes on the object.
• For objects of type Class, by executing a synchronized static method of that class.

The short answer is no. You can play a bit, if you want:

You can always do something like this:

private enum Base
{
    A,
    B,
    C
}

private enum Consume
{
    A = Base.A,
    B = Base.B,
    C = Base.C,
    D,
    E
}

But, it doesn't work all that great because Base.A != Consume.A

You can always do something like this, though:

public static class Extensions
{
    public static T As<T>(this Consume c) where T : struct
    {
        return (T)System.Enum.Parse(typeof(T), c.ToString(), false);
    }
}

In order to cross between Base and Consume...

You could also cast the values of the enums as ints, and compare them as ints instead of enum, but that kind of sucks too.

The extension method return should type cast it type T.

Old Answer (July 2016):

You can't directly debug Chrome for iOS due to restrictions on the published WKWebView apps, but there are a few options already discussed in other SO threads:

1. If you can reproduce the issue in Safari as well, then use Remote Debugging with Safari Web Inspector. This would be the easiest approach.

2. WeInRe allows some simple debugging, using a simple client-server model. It's not fully featured, but it may well be enough for your problem. See instructions on set up here.

3. You could try and create a simple WKWebView browser app (some instructions here), or look for an existing one on GitHub. Since Chrome uses the same rendering engine, you could debug using that, as it will be close to what Chrome produces.

There's a "bug" opened up for WebKit: Allow Web Inspector usage for release builds of WKWebView. If and when we get an API to WKWebView, Chrome for iOS would be debuggable.

Update January 2018:

Since my answer back in 2016, some work has been done to improve things.

There is a recent project called RemoteDebug iOS WebKit Adapter, by some of the Microsoft team. It's an adapter that handles the API differences between Webkit Remote Debugging Protocol and Chrome Debugging Protocol, and this allows you to debug iOS WebViews in any app that supports the protocol - Chrome DevTools, VS Code etc.

Check out the getting started guide in the repo, which is quite detailed.

If you are interesting, you can read up on the background and architecture here.

You should find it in :

C:\Users\User Name\AppData\Local\Android\sdk\platform-tools

Add that to path, or change directory to there. The command sqlite3 is also there.

In the terminal you can type commands like

adb logcat //for logs
adb shell // for android shell

For angular+boilerplate flow which creates next folders tree:

backend/
|
|------ui/
|      |------------------build/          <--'static' folder, constructed by Grunt
|      |--<proj           |----vendors/   <-- angular.js and others here
|      |--     folders>   |----src/       <-- your js
|                         |----index.html <-- your SPA entrypoint 
|------<proj
|------     folders>
|
|------view.py  <-- Flask app here

I use following solution:

...
root = os.path.join(os.path.dirname(os.path.abspath(__file__)), "ui", "build")

@app.route('/<path:path>', methods=['GET'])
def static_proxy(path):
    return send_from_directory(root, path)


@app.route('/', methods=['GET'])
def redirect_to_index():
    return send_from_directory(root, 'index.html')
...

It helps to redefine 'static' folder to custom.

In Python, You can Try...

from encodings.aliases import aliases
alias_values = set(aliases.values())

for encoding in set(aliases.values()):
    try:
        df=pd.read_csv("test.csv", encoding=encoding)
        print('successful', encoding)
    except:
        pass

I decide to publish my example that I used in my case. I tried to replace content in div using a script. My problem was that Chrome did not recognized / did not run that script.

In more detail What I wanted to do: To click on a link, and that link to "read" an external html file, that it will be loaded in a div section.

• I found out that by placing the script before the DIV with ID that was called, the script did not work.
• If the script was in another DIV, also it does not work

• The script must be coded using document.addEventListener('DOMContentLoaded', function() as it was told

      <body>
      <a id=id_page href ="#loving"   onclick="load_services()"> loving   </a>
  
          <script>
                  // This script MUST BE under the "ID" that is calling
                  // Do not transfer it to a differ DIV than the caller "ID"
                  document.getElementById("id_page").addEventListener("click", function(){
                  document.getElementById("mainbody").innerHTML = '<object data="Services.html" class="loving_css_edit"; ></object>'; });
              </script>
      </body>
  
    <div id="mainbody" class="main_body">
          "here is loaded the external html file when the loving link will 
           be  clicked. "
    </div>
  

Technically slice is the fastest way. However, it is even faster if you add the 0 begin index.

myArray.slice(0);

is faster than

myArray.slice();

They can be considered as equivalent. The limits in size are the same:

• Maximum length of CLOB (in bytes or OCTETS)) 2 147 483 647
• Maximum length of BLOB (in bytes) 2 147 483 647

There is also the DBCLOBs, for double byte characters.

You should move it:

Directory.Move(source, destination);

You can use:

newinv=inventory+[add]

but using append is better since it doesn't create a new list:

inventory.append(add)

Swift

let indexpath = IndexPath(row: 0, section: 0)
if let cell = tableView.cellForRow(at: indexPath) as? <UITableViewCell or CustomCell> {
    cell.backgroundColor = UIColor.red
}

An explicit cursor is one you declare, like:

CURSOR my_cursor IS
  SELECT table_name FROM USER_TABLES

An implicit cursor is one created to support any in-line SQL you write (either static or dynamic).

//Suppose function not taking any parameter means just add the GetAlterConfirmation(function(result) {});
GetAlterConfirmation('test','messageText',function(result) {
                        alert(result);
    }); //Function into document load or any other click event.


function GetAlterConfirmation(titleText, messageText, _callback){
         bootbox.confirm({
                    title: titleText,
                    message: messageText,
                    buttons: {
                        cancel: {
                            label: '<i class="fa fa-times"></i> Cancel'
                        },
                        confirm: {
                            label: '<i class="fa fa-check"></i> Confirm'
                        }
                    },
                    callback: function (result) {
                        return _callback(result); 
                    }
                });

1. Reference your messages container.

   <div ref={(el) => { this.messagesContainer = el; }}> YOUR MESSAGES </div>
   

2. Find your messages container and make its scrollTop attribute equal scrollHeight:

   scrollToBottom = () => {
       const messagesContainer = ReactDOM.findDOMNode(this.messagesContainer);
       messagesContainer.scrollTop = messagesContainer.scrollHeight;
   };
   

3. Evoke above method on componentDidMount and componentDidUpdate.

   componentDidMount() {
        this.scrollToBottom();
   }
   
   componentDidUpdate() {
        this.scrollToBottom();
   }
   

This is how I am using this in my code:

 export default class StoryView extends Component {

    constructor(props) {
        super(props);
        this.scrollToBottom = this.scrollToBottom.bind(this);
    }

    scrollToBottom = () => {
        const messagesContainer = ReactDOM.findDOMNode(this.messagesContainer);
        messagesContainer.scrollTop = messagesContainer.scrollHeight;
    };

    componentDidMount() {
        this.scrollToBottom();
    }

    componentDidUpdate() {
        this.scrollToBottom();
    }

    render() {
        return (
            <div>
                <Grid className="storyView">
                    <Row>
                        <div className="codeView">
                            <Col md={8} mdOffset={2}>

Change your css as below

#element1 {float:left;margin-right:10px;} 
#element2 {float:left;} 

Here is the JSFiddle http://jsfiddle.net/a4aME/

Simple example: Form with textbox and Search button.

If you write "name" into the textbox and submit form, it will brings you patients with "name" in table.

View:

@using (Ajax.BeginForm("GetPatients", "Patient", new AjaxOptions {//GetPatients is name of method in PatientController
    InsertionMode = InsertionMode.Replace, //target element(#patientList) will be replaced
    UpdateTargetId = "patientList",
    LoadingElementId = "loader" // div with .gif loader - that is shown when data are loading   
}))
{
    string patient_Name = "";
    @Html.EditorFor(x=>patient_Name) //text box with name and id, that it will pass to controller
    <input  type="submit" value="Search" />
}

@* ... *@
<div id="loader" class=" aletr" style="display:none">
    Loading...<img src="~/Images/ajax-loader.gif" />
</div>
@Html.Partial("_patientList") @* this is view with patient table. Same view you will return from controller *@

_patientList.cshtml:

@model IEnumerable<YourApp.Models.Patient>

<table id="patientList" >
<tr>
    <th>
        @Html.DisplayNameFor(model => model.Name)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.Number)
    </th>       
</tr>
@foreach (var patient in Model) {
<tr>
    <td>
        @Html.DisplayFor(modelItem => patient.Name)
    </td>
    <td>
        @Html.DisplayFor(modelItem => patient.Number)
    </td>
</tr>
}
</table>

Patient.cs

public class Patient
{
   public string Name { get; set; }
   public int Number{ get; set; }
}

PatientController.cs

public PartialViewResult GetPatients(string patient_Name="")
{
   var patients = yourDBcontext.Patients.Where(x=>x.Name.Contains(patient_Name))
   return PartialView("_patientList", patients);
}

And also as TSmith said in comments, don´t forget to install jQuery Unobtrusive Ajax library through NuGet.

I have had a similar issue and looks like that the culprit was the space in the path to the archive (e.g., C:\Program Files\java\jdk). After moving the archive to another directory without spaces in path it started to work.

Here is a simple solution using a dynamically generated style sheet served up by the same server as the iframe content. Quite simply the style sheet "knows" what is in the iframe, and knows the dimensions to use to style the iframe. This gets around the same origin policy restrictions.

http://www.8degrees.co.nz/2010/06/09/dynamically-resize-an-iframe-depending-on-its-content/

So the supplied iframe code would have an accompanying style sheet like so...

<link href="http://your.site/path/to/css?contents_id=1234&dom_id=iframe_widget" rel="stylesheet" type="text/css" />? <iframe id="iframe_widget" src="http://your.site/path/to/content?content_id=1234" frameborder="0" width="100%" scrolling="no"></iframe>

This does require the server side logic being able to calculate the dimensions of the rendered content of the iframe.

As soon as I saw the problem statement, I thought "Trie". But seeing as several other posters made use of that approach, I looked for another approach just to be different. Alas, the Trie approach performs better. I ran Kent's Perl solution on my machine and it took 0.31 seconds to run, after adapting it to use my dictionary file. My own perl implementation required 0.54 seconds to run.

This was my approach:

1. Create a transition hash to model the legal transitions.

2. Iterate through all 16^3 possible three letter combinations.

   • In the loop, exclude illegal transitions and repeat visits to the same square. Form all the legal 3-letter sequences and store them in a hash.

3. Then loop through all words in the dictionary.

   • Exclude words that are too long or short
   • Slide a 3-letter window across each word and see if it is among the 3-letter combos from step 2. Exclude words that fail. This eliminates most non-matches.
   • If still not eliminated, use a recursive algorithm to see if the word can be formed by making paths through the puzzle. (This part is slow, but called infrequently.)

4. Print out the words I found.

   I tried 3-letter and 4-letter sequences, but 4-letter sequences slowed the program down.

In my code, I use /usr/share/dict/words for my dictionary. It comes standard on MAC OS X and many Unix systems. You can use another file if you want. To crack a different puzzle, just change the variable @puzzle. This would be easy to adapt for larger matrices. You would just need to change the %transitions hash and %legalTransitions hash.

The strength of this solution is that the code is short, and the data structures simple.

Here is the Perl code (which uses too many global variables, I know):

#!/usr/bin/perl

October 2015 Update

This answer was posted several years ago and now the question really should be should you even consider using the X-UA-Compatible tag on your site? with the changes Microsoft has made to its browsers (more on those below).

Depending upon what Microsoft browsers you support you may not need to continue using the X-UA-Compatible tag. If you need to support IE9 or IE8, then I would recommend using the tag. If you only support the latest browsers (IE11 and/or Edge) then I would consider dropping this tag altogether. If you use Twitter Bootstrap and need to eliminate validation warnings, this tag must appear in its specified order. Additional info below:

The X-UA-Compatible meta tag allows web authors to choose what version of Internet Explorer the page should be rendered as. IE11 has made changes to these modes; see the IE11 note below. Microsoft Edge, the browser that replaced IE11, only honors the X-UA-Compatible meta tag in certain circumstances. See the Microsoft Edge note below.

According to Microsoft, when using the X-UA-Compatible tag, it should be as high as possible in your document head:

If you are using the X-UA-Compatible META tag you want to place it as close to the top of the page's HEAD as possible. Internet Explorer begins interpreting markup using the latest version. When Internet Explorer encounters the X-UA-Compatible META tag it starts over using the designated version's engine. This is a performance hit because the browser must stop and restart analyzing the content.

Here are your options:

• "IE=edge"
• "IE=11"
• "IE=EmulateIE11"
• "IE=10"
• "IE=EmulateIE10"
• "IE=9"
• "IE=EmulateIE9
• "IE=8"
• "IE=EmulateIE8"
• "IE=7"
• "IE=EmulateIE7"
• "IE=5"

To attempt to understand what each means, here are definitions provided by Microsoft:

Internet Explorer supports a number of document compatibility modes that enable different features and can affect the way content is displayed:

• Edge mode tells Internet Explorer to display content in the highest mode available. With Internet Explorer 9, this is equivalent to IE9 mode. If a future release of Internet Explorer supported a higher compatibility mode, pages set to edge mode would appear in the highest mode supported by that version. Those same pages would still appear in IE9 mode when viewed with Internet Explorer 9. Internet Explorer supports a number of document compatibility modes that enable different features and can affect the way content is displayed:

• IE11 mode provides the highest support available for established and emerging industry standards, including the HTML5, CSS3 and others.

• IE10 mode provides the highest support available for established and emerging industry standards, including the HTML5, CSS3 and others.

• IE9 mode provides the highest support available for established and emerging industry standards, including the HTML5 (Working Draft), W3C Cascading Style Sheets Level 3 Specification (Working Draft), Scalable Vector Graphics (SVG) 1.0 Specification, and others. [Editor Note: IE 9 does not support CSS3 animations].

• IE8 mode supports many established standards, including the W3C Cascading Style Sheets Level 2.1 Specification and the W3C Selectors API; it also provides limited support for the W3C Cascading Style Sheets Level 3 Specification (Working Draft) and other emerging standards.

• IE7 mode renders content as if it were displayed in standards mode by Internet Explorer 7, whether or not the page contains a directive.

• Emulate IE9 mode tells Internet Explorer to use the directive to determine how to render content. Standards mode directives are displayed in IE9 mode and quirks mode directives are displayed in IE5 mode. Unlike IE9 mode, Emulate IE9 mode respects the directive.

• Emulate IE8 mode tells Internet Explorer to use the directive to determine how to render content. Standards mode directives are displayed in IE8 mode and quirks mode directives are displayed in IE5 mode. Unlike IE8 mode, Emulate IE8 mode respects the directive.

• Emulate IE7 mode tells Internet Explorer to use the directive to determine how to render content. Standards mode directives are displayed in Internet Explorer 7 standards mode and quirks mode directives are displayed in IE5 mode. Unlike IE7 mode, Emulate IE7 mode respects the directive. For many web sites, this is the preferred compatibility mode.

• IE5 mode renders content as if it were displayed in quirks mode by Internet Explorer 7, which is very similar to the way content was displayed in Microsoft Internet Explorer 5.

IE10 NOTE: As of IE10, quirks mode behaves differently than it did in earlier versions of the browser. In IE9 and earlier versions, quirks mode restricted the webpage to the features supported by IE5.5. In IE10, quirks mode conforms to the differences specified in the HTML5 specification.

Personally, I always choose the http-equiv="X-UA-Compatible" content="IE=edge" meta tag, as older versions have plenty of bugs, and I do not want IE to decide to go into "Compatibility mode" and show my site as IE7 vs IE8 or 9. I always prefer the latest version of IE.

IE11

From Microsoft:

Starting with IE11, edge mode is the preferred document mode; it represents the highest support for modern standards available to the browser.

Use the HTML5 document type declaration to enable edge mode:

<!doctype html>

Edge mode was introduced in Internet Explorer 8 and has been available in each subsequent release. Note that the features supported by edge mode are limited to those supported by the specific version of the browser rendering the content.

Starting with IE11, document modes are deprecated and should no longer be used, except on a temporary basis. Make sure to update sites that rely on legacy features and document modes to reflect modern standards.

If you must target a specific document mode so that your site functions while you rework it to support modern standards and features, be aware that you're using a transitional feature, one that may not be available in future versions.

If you currently use the x-ua-compatible header to target a legacy document mode, it's possible your site won't reflect the best experience available with IE11.

Microsoft Edge (Replacement for Internet Explorer that comes bundled with Windows 10)

Information on X-UA-Compatible meta tag for the "Edge" version of IE. From Microsoft:

Introducing the “living” Edge document mode

As we announced in August 2013, we are deprecating document modes as of IE11. With our latest platform updates, the need for legacy document modes is primarily limited to Enterprise legacy web apps. With new architectural changes, these legacy document modes will be isolated from changes in the “living” Edge mode, which will help to guarantee a much higher level of compatibility for customers who depend on those modes and help us move even faster on improvements in Edge. IE will still honor document modes served by intranet sites, sites on the Compatibility View list, and when used with Enterprise Mode only.

Public Internet sites will be rendered with the new Edge mode platform (ignoring X-UA-Compatible). It is our goal that Edge is the "living" document mode from here out and no further document modes will be introduced going forward.

With the changes in Microsoft Edge to no longer support document modes in most cases, Microsoft has a tool to scan your site to check and see if it has code that is not compatible with Edge.

Chrome=1 Info for IE

There is also chrome=1 that you can use or use together with one of the above options like: <meta http-equiv="X-UA-Compatible" content="IE=Edge,chrome=1">. chrome=1 is for Google's Chrome Frame which is defined as:

Google Chrome Frame is an open source browser plug-in. Users who have the plug-in installed have access to Google Chrome's open web technologies and speedy JavaScript engine when they open pages in the browser.

Google Chrome Frame seamlessly enhances your browsing experience in Internet Explorer. It displays Google Chrome Frame enabled sites using Google Chrome’s rendering technology, giving you access to the latest HTML5 features as well as Google Chrome’s performance and security features without in any way interrupting your usual browser usage.

When Google Chrome Frame is installed, the web just gets better without you having to think about it.

But for that plug-in to work you must use chrome=1 in the X-UA-Compatible meta tag.

More info on Chrome Frame can be found here.

Note: Google Chrome Frame only works for IE6 through IE9, and was retired on February 25, 2014. More info can be found here. Thanks to @mck for the link.

Validation:

HTML5:

The page will validate using the W3 Validator only when using <meta http-equiv="X-UA-Compatible" content="IE=Edge">. For other values it will throw the error: A meta element with an http-equiv attribute whose value is X-UA-Compatible must have a content attribute with the value IE=edge. In other words, if you have IE=edge,chrome=1 it will not validate. I ignore this error completely as modern browsers simply ignore this line of code.

If you must have completely valid code then consider doing this on the server level by setting HTTP header. As a note, Microsoft says, If both of these instructions are sent (meta and HTTP), the developer's preference (meta element) takes precedence over the web server setting (HTTP header). See olibre's answer or bitinn's answer for more details on how to set an HTTP header.

XHTML

There isn't an issue with validation when using <meta http-equiv="X-UA-Compatible" content="IE=Edge" /> as long as the tag is properly closed (i.e. /> vs >).

Twitter Bootstrap

This tag has been strongly recommended by the Bootstrap team since at least 2014, and Bootlint, the linter authored by the twbs team continues to throw a warning when the tag is omitted. The linter distinguishes between warnings and errors, and as such the severity of omitting this tag may be considered minor.

For more information on X-UA-Compatible see Microsoft's Website Defining Document Compatibility.

For more information on what IE supports see caniuse.com.

For more information on Twitter Bootstrap requirements, see the bootlint project wiki page.

My solution was to select the maven profiles I had defined in my pom.xml in which I had declared the hibernate dependencies.

CTRL + ALT + P in eclipse.

In my project I was experiencing this problem and many others because in my pom I have different profiles for supporting Glassfish 3, Glassfish 4 and also WildFly so I have differet versions of Hibernate per container as well as different Java compilation targets and so on. Selecting the active maven profiles resolved my issue.

The way without re-inserting all entries into the new map should be the fastest it won't because HashMap.clone internally performs rehash as well.

Map<String, Column> newColumnMap = originalColumnMap.clone();
newColumnMap.replaceAll((s, c) -> new Column(c));

There are many ways. You use RelativeLayout or AbsoluteLayout.

With relative, you can have the image align with parent on the left side for example and also have the text align to the parent left too... then you can use margins and padding and gravity on the text view to get it lined where you want over the image.

Do what Kelly said...

BUT. Instead of having the input positioned absolute and top -20px (just hiding it off the page), make the input box hidden.

example:

<input type="checkbox" hidden> 

Works better and can put it anywhere on the page.

This actually sums it up pretty nicely.

API Levels generally mean that as a programmer, you can communicate with the devices' built in functions and functionality. As the API level increases, functionality adds up (although some of it can get deprecated).

Choosing an API level for an application development should take at least two thing into account:

1. Current distribution - How many devices can actually support my application, if it was developed for API level 9, it cannot run on API level 8 and below, then "only" around 60% of devices can run it (true to the date this post was made).
2. Choosing a lower API level may support more devices but gain less functionality for your app. you may also work harder to achieve features you could've easily gained if you chose higher API level.

Android API levels can be divided to five main groups (not scientific, but what the heck):

1. Android 1.5 - 2.3 (Cupcake to Gingerbread) - (API levels 3-10) - Android made specifically for smartphones.
2. Android 3.0 - 3.2 (Honeycomb) (API levels 11-13) - Android made for tablets.
3. Android 4.0 - 4.4 (KitKat) - (API levels 14-19) - A big merge with tons of additional functionality, totally revamped Android version, for both phone and tablets.
4. Android 5.0 - 5.1 (Lollipop) - (API levels 21-22) - Material Design introduced.
5. Android 6.0 - 6.… (Marshmallow) - (API levels 23-…) - Runtime Permissions,Apache HTTP Client Removed

Use percent encoding. Modern browsers will take care of display & paste issues and make it human-readable. E. g. http://ko.wikipedia.org/wiki/????:??

Edit: when you copy such an url in Firefox, the clipboard will hold the percent-encoded form (which is usually a good thing), but if you copy only a part of it, it will remain unencoded.

There are two issues with the code in the original question: there should not be a : in the timezone and the format string for "timezone as an offset" is lower case %z not upper %Z.

This works for me in Python v3.6

>>> from datetime import datetime
>>> t = datetime.strptime("2012-11-01T04:16:13-0400", "%Y-%m-%dT%H:%M:%S%z")
>>> print(t)
2012-11-01 04:16:13-04:00

This is a quick way to do that, I mean.

It does not use an expensive regex function. It also does not use multiple replacement functions that each individually did loop over the data with several checks, allocations, etc.

So the search is done directly in one for loop. For the number of times that the capacity of the result array has to be increased, a loop is also used within the Array.Copy function. That are all the loops. In some cases, a larger page size might be more efficient.

public static string NormalizeNewLine(this string val)

}

I now that '\n\r' is not actually used on basic platforms. But who would use two types of linebreaks in succession to indicate two linebreaks?

If you want to know that, then you need to take a look before to know if the \n and \r both are used separately in the same document.

If you want to increase the height of the input field, you can specify line-height css property for the input field.

input {
    line-height: 2em; // 2em is (2 * default line height)
}

\n is Unix, \r is Mac, \r\n is Windows.

Sometimes it's giving trouble especially when running code cross platform. You can bypass this by using Environment.NewLine.

Please refer to What is the difference between \r, \n and \r\n ?! for more information. Happy reading

I faced a similar issue, and I solved that after doing the following:

1. check your jupyter configuration file: this is described here in details; https://testnb.readthedocs.io/en/stable/examples/Notebook/Configuring%20the%20Notebook%20and%20Server.html

-- you will simply need from the link above to learn how to make jupyter server listens to your local machin IP -- you will need to know your local machin IP (i use "ifconfig -a" on ubuntu to find that out) - please check for centos6

after you finish setting your configuration, you can run jupyter notebook at your local IP: jupyter notebook --ip=* --no-browser

please replace * with your IP address for example: jupyter notebook --ip=192.168.x.x --no-browser

you can now access your jupyter server from any device connected to the router using this ip:port (the port is usually 8888, so for my case for instance I used "192.168.x.x:8888" to access my server from other devices)

now if you want to access this server from public IP, you will have to:

1. find your public IP (simply type on google what is my IP)
2. use this IP address instead of your local IP to access the server from any device not connected to the same router kindly note: if your linux server runs on Virtual machine, you will need to set your router to allow accessing your VB from public IPs, settings depends on the router type. otherwise, you should be able to access the server using the public IP and the port set for it from any device not connected to your router, or using your local IP and the port set from any device connected to the same router!

FOR %%A IN (%*) DO (
    REM Now your batch file handles %%A instead of %1
    REM No need to use SHIFT anymore.
    ECHO %%A
)

This loops over the batch parameters (%*) either they are quoted or not, then echos each parameter.

I'm not up on my PowerShell syntax, but I think you could just call System.Runtime.InteropServices.RuntimeEnvironment.GetSystemVersion(). This will return the version as a string (something like v2.0.50727, I think).

If you just want the last date for each account, you'd use this:

var q = from n in table
        group n by n.AccountId into g
        select new {AccountId = g.Key, Date = g.Max(t=>t.Date)};

If you want the whole record:

var q = from n in table
        group n by n.AccountId into g
        select g.OrderByDescending(t=>t.Date).FirstOrDefault();

System.in.read() reads from the standard input.

The standard input can be used to get input from user in a console environment but, as such user interface has no editing facilities, the interactive use of standard input is restricted to courses that teach programming.

Most production use of standard input is in programs designed to work inside Unix command-line pipelines. In such programs the payload that the program is processing is coming from the standard input and the program's result gets written to the standard output. In that case the standard input is never written directly by the user, it is the redirected output of another program or the contents of a file.

A typical pipeline looks like this:

# list files and directories ordered by increasing size
du -s * | sort -n

sort reads its data from the standard input, which is in fact the output of the du command. The sorted data is written to the standard output of sort, which ends up on the console by default, and can be easily redirected to a file or to another command.

As such, the standard input is comparatively rarely used in Java.

Call this function:

  public int[] convertToArray(int number) {
    int i = 0;
    int length = (int) Math.log10(number);
    int divisor = (int) Math.pow(10, length);
    int temp[] = new int[length + 1];

    while (number != 0) {
        temp[i] = number / divisor;
        if (i < length) {
            ++i;
        }
        number = number % divisor;
        if (i != 0) {
            divisor = divisor / 10;
        }
    }
    return temp;
}

Try filter to subset only the rows of P1 and P3

df2 <- filter(df, ID == "P1" | ID == "P3")

Than yo can plot Value1. vs Value2.

I know this is old but if you do a split then join it will remove all occurrences of a particular character ie:

var str = theText.split('A').join('')

will remove all occurrences of 'A' from the string, obviously it's not case sensitive

I went with a modification of @user1097431 's answer:

function menuPosition(){
// distance from top of footer to top of document
var footertotop = ($('.footer').position().top);
// distance user has scrolled from top, adjusted to take in height of bar (42 pixels inc. padding)
var scrolltop = $(document).scrollTop() + window.innerHeight;
// difference between the two
var difference = scrolltop-footertotop;

// if user has scrolled further than footer,
// pull sidebar up using a negative margin
if (scrolltop > footertotop) {
    $('#categories-wrapper').css({
       'bottom' : difference
   });
}else{
    $('#categories-wrapper').css({
       'bottom' : 0
   });
 };
};

in case somebody still needs it, and since nothing here really worked for me, i came up with a very simple way that keeps the appearance of the generated plot "as is" while fixing the number of ticks to exactly N:

import numpy as np
import matplotlib.pyplot as plt

f, ax = plt.subplots()
ax.plot(range(100))

ymin, ymax = ax.get_ylim()
ax.set_yticks(np.round(np.linspace(ymin, ymax, N), 2))

There are couple of good free service that let you do the same. Ideal for showing something quickly for testing:

• http://localtunnel.me/
• https://ngrok.com/
• http://localhost.run/

Edits:

• add ngrok service
• add localhost.run service

The first method is right.

The second method kills kittens if you attempt to do anything with x after the fact other than Object methods.

T must be defined within the scope in which you are working. Therefore, what you have posted will work if your class is generic on T:

public class MyClass<T>
{
    private List<T> newList;

    public List<T> NewList
    {
        get{return newList;}
        set{newList = value;}
    }
}

Otherwise, you have to use a defined type.

EDIT: Per @lKashef's request, following is how to have a List property:

private List<int> newList;

public List<int> NewList
{
    get{return newList;}
    set{newList = value;}
}

This can go within a non-generic class.

Edit 2: In response to your second question (in your edit), I would not recommend using a list for this type of data handling (if I am understanding you correctly). I would put the user settings in their own class (or struct, if you wish) and have a property of this type on your original class:

public class UserSettings
{
 string FirstName { get; set; }
 string LastName { get; set; }
 // etc.
}

public class MyClass
{
 string MyClassProperty1 { get; set; }
 // etc.

 UserSettings MySettings { get; set; }
}

This way, you have named properties that you can reference instead of an arbitrary index in a list. For example, you can reference MySettings.FirstName as opposed to MySettingsList[0].

Let me know if you have any further questions.

EDIT 3: For the question in the comments, your property would be like this:

public class MyClass
{
    public List<KeyValuePair<string, string>> MySettings { get; set; } 
}

EDIT 4: Based on the question's edit 2, following is how I would use this:

public class MyClass
{
    // note that this type of property declaration is called an "Automatic Property" and
    // it means the same thing as you had written (the private backing variable is used behind the scenes, but you don't see it)
    public List<KeyValuePair<string, string> MySettings { get; set; } 
}

public class MyConsumingClass
{
    public void MyMethod
    {
        MyClass myClass = new MyClass();
        myClass.MySettings = new List<KeyValuePair<string, string>>();
        myClass.MySettings.Add(new KeyValuePair<string, string>("SomeKeyValue", "SomeValue"));

        // etc.
    }
}

You mentioned that "the property still won't appear in the object's instance," and I am not sure what you mean. Does this property not appear in IntelliSense? Are you sure that you have created an instance of MyClass (like myClass.MySettings above), or are you trying to access it like a static property (like MyClass.MySettings)?

You just use the method

public Object put(Object key, Object value)

if the key was already present in the Map then the previous value is returned.

I realize the following suggestion doesn't answer your question, but the simplest method I have found to capture a rapidly-changing DirectX view, is to plug a video camera into the S-video port of the video card, and record the images as a movie. Then transfer the video from the camera back to an MPG, WMV, AVI etc. file on the computer.

XDebug changed some configuration settings.

Old settings:

xdebug.remote_enable = 1
xdebug.remote_autostart = 1
xdebug.remote_port = 9000

New settings:

xdebug.mode=debug
xdebug.start_with_request=yes
xdebug.client_port=9000

So you should paste the latter in php.ini file. More info: XDebug Changed Configuration Settings

Check out the example from enable-cors.org:

In your ExpressJS app on node.js, do the following with your routes:

app.all('/', function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Headers", "X-Requested-With");
  next();
 });

app.get('/', function(req, res, next) {
  // Handle the get for this route
});

app.post('/', function(req, res, next) {
 // Handle the post for this route
});

The first call (app.all) should be made before all the other routes in your app (or at least the ones you want to be CORS enabled).

[Edit]

If you want the headers to show up for static files as well, try this (make sure it's before the call to use(express.static()):

app.use(function(req, res, next) {
  res.header("Access-Control-Allow-Origin", "*");
  res.header("Access-Control-Allow-Headers", "X-Requested-With");
  next();
});

I tested this with your code, and got the headers on assets from the public directory:

var express = require('express')
  , app = express.createServer();

app.configure(function () {
    app.use(express.methodOverride());
    app.use(express.bodyParser());
    app.use(function(req, res, next) {
      res.header("Access-Control-Allow-Origin", "*");
      res.header("Access-Control-Allow-Headers", "X-Requested-With");
      next();
    });
    app.use(app.router);
});

app.configure('development', function () {
    app.use(express.static(__dirname + '/public'));
    app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));
});

app.configure('production', function () {
    app.use(express.static(__dirname + '/public'));
    app.use(express.errorHandler());
});

app.listen(8888);
console.log('express running at http://localhost:%d', 8888);

You could, of course, package the function up into a module so you can do something like

// cors.js

module.exports = function() {
  return function(req, res, next) {
    res.header("Access-Control-Allow-Origin", "*");
    res.header("Access-Control-Allow-Headers", "X-Requested-With");
    next();
  };
}

// server.js

cors = require('./cors');
app.use(cors());

You can always point to your home directory using ~ then you can refer to your data folder.

import pandas as pd
df = pd.read_csv("~/mydata/data.csv")

For your case, it should be like this

import pandas as pd
df = pd.read_csv("~/folder/folder2/data_folder/data.csv")

You can also set your data directory as a prefix

import pandas as pd
DATA_DIR = "~/folder/folder2/data_folder/"
df = pd.read_csv(DATA_DIR+"data.csv")

You can take advantage of f-strings as @nikos-tavoularis said

import pandas as pd
DATA_DIR = "~/folder/folder2/data_folder/"
FILE_NAME = "data.csv"
df = pd.read_csv(f"{DATA_DIR}{FILE_NAME}")

I agree with user3158900, and I only differ slightly in the way I use it:

{{Form::label('sports', 'Sports')}}
{{Form::select('sports',$aSports,null,array('multiple'=>'multiple','name'=>'sports[]'))}}

However, in my experience the 3rd parameter of the select is a string only, so for repopulating data for a multi-select I have had to do something like this:

<select multiple="multiple" name="sports[]" id="sports">
@foreach($aSports as $aKey => $aSport)
    @foreach($aItem->sports as $aItemKey => $aItemSport)
        <option value="{{$aKey}}" @if($aKey == $aItemKey)selected="selected"@endif>{{$aSport}}</option>
    @endforeach
@endforeach
</select>

You should take a look at Java date formatting, in particular SimpleDateFormat. There's some examples here: http://download.oracle.com/javase/tutorial/i18n/format/simpleDateFormat.html - but you can also find a lot more with a quick google.

Marc response is correct. Actually, you can print the memory address for the variables print(hex(id(libvar)) and you can see the addresses are different.

# mylib.py
libvar = None
def lib_method():
    global libvar
    print(hex(id(libvar)))

# myapp.py
from mylib import libvar, lib_method
import mylib

lib_method()
print(hex(id(libvar)))
print(hex(id(mylib.libvar)))

You could also set onclick to call your function like this:

foo.onclick = function() { callYourJSFunction(arg1, arg2); };

This way, you can pass arguments too. .....

This just happened to me using Android Studio 1.3.2, however, since I had just created the project, I deleted it and created it again.
It seems that it had not been properly created by Android Studio the first time, not even the project folders where as expected.

Here is an updated method with syntax that is more common in python code. It also prevents you from opening the same file multiple times.

import pandas as pd

sheet1, sheet2 = None, None
with pd.ExcelFile("PATH\FileName.xlsx") as reader:
    sheet1 = pd.read_excel(reader, sheet_name='Sheet1')
    sheet2 = pd.read_excel(reader, sheet_name='Sheet2')

After discussing with the hosting of my SVN repository they gave me the following answer.

Apparently my repository is replicated to a remote repository using SVNSYNC. SVNSYNC has known limitations with enforcing locking across the replicated repositories and this is where the problem lies.

The locks were introduced by the AnkhSVN plugin in Visual Studio.

As the locks appears to be on the remote repository this explains why I can't actually see them using SVN commands.

The locks are being removed via the hosting company and hopefully all will soon be well again.

There is Java Plugin to use string interpolation in Java (like in Kotlin, JavaScript). Supports Java 8, 9, 10, 11…? https://github.com/antkorwin/better-strings

Using variables in string literals:

int a = 3;
int b = 4;
System.out.println("${a} + ${b} = ${a+b}");

Using expressions:

int a = 3;
int b = 4;
System.out.println("pow = ${a * a}");
System.out.println("flag = ${a > b ? true : false}");

Using functions:

@Test
void functionCall() {
    System.out.println("fact(5) = ${factorial(5)}");
}

long factorial(int n) {
    long fact = 1;
    for (int i = 2; i <= n; i++) {
        fact = fact * i;
    }
    return fact;
}

For more info, please read the project README.

I tried sudo apt install nginx-full. You will get all the required packages.

Its not mentioned on doc, but Left sidebar on Bootstrap 3 is possible using "Collapse" method.

As mentioned by bootstrap.js :

Collapse.prototype.dimension = function () {
    var hasWidth = this.$element.hasClass('width')
    return hasWidth ? 'width' : 'height'
  }

This mean, adding class "width" into target, will expand by width instead of height :

As others have said multiprocessing can only transfer Python objects to worker processes which can be pickled. If you cannot reorganize your code as described by unutbu, you can use dills extended pickling/unpickling capabilities for transferring data (especially code data) as I show below.

This solution requires only the installation of dill and no other libraries as pathos:

import os
from multiprocessing import Pool

import dill


def run_dill_encoded(payload):
    fun, args = dill.loads(payload)
    return fun(*args)


def apply_async(pool, fun, args):
    payload = dill.dumps((fun, args))
    return pool.apply_async(run_dill_encoded, (payload,))


if __name__ == "__main__":

    pool = Pool(processes=5)

    # asyn execution of lambda
    jobs = []
    for i in range(10):
        job = apply_async(pool, lambda a, b: (a, b, a * b), (i, i + 1))
        jobs.append(job)

    for job in jobs:
        print job.get()
    print

    # async execution of static method

    class O(object):

        @staticmethod
        def calc():
            return os.getpid()

    jobs = []
    for i in range(10):
        job = apply_async(pool, O.calc, ())
        jobs.append(job)

    for job in jobs:
        print job.get()

Use the REPLACE function.

eg: SELECT REPLACE ('t?es?t', '?', 'w');

Source

That will select (by a regex) every book which has a title starting with a number, is that what you want?

SELECT * FROM books WHERE title ~ '^[0-9]'

if you want integers which start with specific digits, you could use:

SELECT * FROM books WHERE CAST(price AS TEXT) LIKE '123%'

or use (if all your numbers have the same number of digits (a constraint would be useful then))

SELECT * FROM books WHERE price BETWEEN 123000 AND 123999;

like so:

BEGIN TRANSACTION; 
UPDATE table_name
  SET column_name=REPLACE(column_name,'text_to_find','replace_with_this'); 
COMMIT TRANSACTION;

Example: Replaces <script... with <a ... to eliminate javascript vulnerabilities

BEGIN TRANSACTION; UPDATE testdb
SET title=REPLACE(title,'script','a'); COMMIT TRANSACTION;

I had this issue. Tracked it down after trying most the other answers on this question. It was caused by the owner and permissions of the /var/lib/nginx and more specifically the /var/lib/nginx/tmp directory being incorrect.

The tmp directory is used by fast-cgi to cache responses as they are generated, but only if they are above a certain size. So the issue is intermittent and only occurs when the generated response is large.

Check the nginx <host_name>.error_log to see if you are having permission issues.

To fix, ensure the owner and group of /var/lib/nginx and all sub-dirs is nginx.

I have also seen this intermittently occur when space on the storage device is too low to create the temporary file. The solution in this case is to free up some space on the device.

To get the eth0 interface MAC address,

import psutil

nics = psutil.net_if_addrs()['eth0']

for interface in nics:
   if interface.family == 17:
      print(interface.address)

It seems that Microsoft themselves prefer <> to != as evidenced in their table constraints. I personally prefer using != because I clearly read that as "not equal", but if you enter [field1 != field2] and save it as a constrait, the next time you query it, it will show up as [field1 <> field2]. This says to me that the correct way to do it is <>.

OAuth v2 specs indicates:

Access token attributes and the methods used to access protected resources are beyond the scope of this specification and are defined by companion specifications.

My Authorisation Server has a webservice (SOAP) endpoint that allows the Resource Server to know whether the access_token is valid.

I did a quick test in both node and chrome and found in both cases += is faster:

var profile = func => { 
    var start = new Date();
    for (var i = 0; i < 10000000; i++) func('test');
    console.log(new Date() - start);
}
profile(x => "testtesttesttesttest");
profile(x => `${x}${x}${x}${x}${x}`);
profile(x => x + x + x + x + x );
profile(x => { var s = x; s += x; s += x; s += x; s += x; return s; });
profile(x => [x, x, x, x, x].join(""));
profile(x => { var a = [x]; a.push(x); a.push(x); a.push(x); a.push(x); return a.join(""); });

results in node: 7.0.10

I suggest to put id to the input, and close the window by callback function as the following:

<input id="close_window" type="button" class="btn btn-success"
                   style="font-weight: bold;display: inline;"
                   value="Close">

The callback function as the following:

<script>
   $('#close_window').on('click', function(){
      window.opener = self;
      window.close();
   });
</script>

I think sometimes onclick doesn't work, check the following answer also.

I also had this problem on a Server 2012 R2 VM joined to my local AD domain. I eventually solved the problem by taking the VM off the domain and re-joining it.

Here is what I would recommend.

It should conform to C89, and be completely portable. In particular, it works also on pipes and sockets on POSIXy systems.

The idea is that we read the input in large-ish chunks (READALL_CHUNK), dynamically reallocating the buffer as we need it. We only use realloc(), fread(), ferror(), and free():

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

/* Size of each input chunk to be
   read and allocate for. */
#ifndef  READALL_CHUNK
#define  READALL_CHUNK  262144
#endif

#define  READALL_OK          0  /* Success */
#define  READALL_INVALID    -1  /* Invalid parameters */
#define  READALL_ERROR      -2  /* Stream error */
#define  READALL_TOOMUCH    -3  /* Too much input */
#define  READALL_NOMEM      -4  /* Out of memory */

/* This function returns one of the READALL_ constants above.
   If the return value is zero == READALL_OK, then:
     (*dataptr) points to a dynamically allocated buffer, with
     (*sizeptr) chars read from the file.
     The buffer is allocated for one extra char, which is NUL,
     and automatically appended after the data.
   Initial values of (*dataptr) and (*sizeptr) are ignored.
*/
int readall(FILE *in, char **dataptr, size_t *sizeptr)
{
    char  *data = NULL, *temp;
    size_t size = 0;
    size_t used = 0;
    size_t n;

    /* None of the parameters can be NULL. */
    if (in == NULL || dataptr == NULL || sizeptr == NULL)
        return READALL_INVALID;

    /* A read error already occurred? */
    if (ferror(in))
        return READALL_ERROR;

    while (1) {

        if (used + READALL_CHUNK + 1 > size) {
            size = used + READALL_CHUNK + 1;

            /* Overflow check. Some ANSI C compilers
               may optimize this away, though. */
            if (size <= used) {
                free(data);
                return READALL_TOOMUCH;
            }

            temp = realloc(data, size);
            if (temp == NULL) {
                free(data);
                return READALL_NOMEM;
            }
            data = temp;
        }

        n = fread(data + used, 1, READALL_CHUNK, in);
        if (n == 0)
            break;

        used += n;
    }

    if (ferror(in)) {
        free(data);
        return READALL_ERROR;
    }

    temp = realloc(data, used + 1);
    if (temp == NULL) {
        free(data);
        return READALL_NOMEM;
    }
    data = temp;
    data[used] = '\0';

    *dataptr = data;
    *sizeptr = used;

    return READALL_OK;
}

Above, I've used a constant chunk size, READALL_CHUNK == 262144 (256*1024). This means that in the worst case, up to 262145 chars are wasted (allocated but not used), but only temporarily. At the end, the function reallocates the buffer to the optimal size. Also, this means that we do four reallocations per megabyte of data read.

The 262144-byte default in the code above is a conservative value; it works well for even old minilaptops and Raspberry Pis and most embedded devices with at least a few megabytes of RAM available for the process. Yet, it is not so small that it slows down the operation (due to many read calls, and many buffer reallocations) on most systems.

For desktop machines at this time (2017), I recommend a much larger READALL_CHUNK, perhaps #define READALL_CHUNK 2097152 (2 MiB).

Because the definition of READALL_CHUNK is guarded (i.e., it is defined only if it is at that point in the code still undefined), you can override the default value at compile time, by using (in most C compilers) -DREADALL_CHUNK=2097152 command-line option -- but do check your compiler options for defining a preprocessor macro using command-line options.

You can only use one color but as many images as you want, here is the format:

background: [ <bg-layer> , ]* <final-bg-layer>

<bg-layer> = <bg-image> || <bg-position> [ / <bg-size> ]? || <repeat-style> || <attachment> || <box>{1,2}

<final-bg-layer> = <bg-image> || <bg-position> [ / <bg-size> ]? || <repeat-style> || <attachment> || <box>{1,2} || <background-color>

or background: url(image1.png) center bottom no-repeat, url(image2.png) left top no-repeat;

If you need more colors, make an image of a solid color and use it. I know it’s not what you want to hear, but I hope it helps.

The format is from http://www.css3.info/preview/multiple-backgrounds/

Open res -> values -> styles.xml and to your <style> add this line replacing with your image path <item name="android:windowBackground">@drawable/background</item>. Example:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:windowBackground">@drawable/background</item>
    </style>

</resources>

There is a <item name ="android:colorBackground">@color/black</item> also, that will affect not only your main window background but all the component in your app. Read about customize theme here.

If you want version specific styles:

If a new version of Android adds theme attributes that you want to use, you can add them to your theme while still being compatible with old versions. All you need is another styles.xml file saved in a values directory that includes the resource version qualifier. For example:

res/values/styles.xml        # themes for all versions
res/values-v21/styles.xml    # themes for API level 21+ only

Because the styles in the values/styles.xml file are available for all versions, your themes in values-v21/styles.xml can inherit them. As such, you can avoid duplicating styles by beginning with a "base" theme and then extending it in your version-specific styles.

Read more here(doc in theme).

Suppose the pattern you want is abc+d. You want to match the second occurrence of this pattern in a string.

You would construct the following regex:

abc+d.*?(abc+d)

This would match strings of the form: <your-pattern>...<your-pattern>. Since we're using the reluctant qualifier *? we're safe that there cannot be another match of between the two. Using matcher groups which pretty much all regex implementations provide you would then retrieve the string in the bracketed group which is what you want.

use it:

.CopyToDataTable()

example:

string _sqlWhere = "Nachname = 'test'";
string _sqlOrder = "Nachname DESC";

DataTable _newDataTable = yurDateTable.Select(_sqlWhere, _sqlOrder).CopyToDataTable();

Use the CREATE TABLE SELECT syntax.

http://dev.mysql.com/doc/refman/5.0/en/create-table-select.html

CREATE TABLE new_tbl SELECT * FROM orig_tbl;
