I would use the Dictionary<TKey, TValue> (so long as each key is unique).

EDIT: Sorry, realised you wanted to add it to a specific position. My bad. You could use a SortedDictionary but this still won't let you insert.

1. Create a class which contains all properties you need, and populate them in the constructor

   class Student
   {
       int _StudentId;
       public int StudentId {get;}
       string _Name;
       public string Name {get;}
       ...
   
       public Student(int studentId, string name ...)
       { _StudentId = studentId; _Name = name; ... }
   }
   

2. Create an IComparer < Student > class, to be able to sort

   class StudentSorter : IComparer<Student>
   {
       public enum SField {StudentId, Name ... }
       SField _sField; SortOrder _sortOrder;
   
       public StudentSorder(SField field, SortOrder order)
       { _sField = field; _sortOrder = order;}
   
       public int Compare(Student x, Student y)
       {
           if (_SortOrder == SortOrder.Descending)
           {
               Student tmp = x;
               x = y;
               y = tmp;
           }
   
           if (x == null || y == null)
               return 0;
   
           int result = 0;
           switch (_sField)
           {
               case SField.StudentId:
                   result = x.StudentId.CompareTo(y.StudentId);
                   break;
               case SField.Name:
                   result = x.Name.CompareTo(y.Name);
                   break;
                   ...
           }
   
           return result;
       }
   }
   

3. Within the form containing the datagrid add

   ListDictionary sortOrderLD = new ListDictionary(); //if less than 10 columns
   private SortOrder SetOrderDirection(string column)
   {
       if (sortOrderLD.Contains(column))
       {
           sortOrderLD[column] = (SortOrder)sortOrderLD[column] == SortOrder.Ascending ? SortOrder.Descending : SortOrder.Ascending;
       }
       else
       {
           sortOrderLD.Add(column, SortOrder.Ascending);
       }
   
       return (SortOrder)sortOrderLD[column];
   }
   

4. Within datagridview_ColumnHeaderMouseClick event handler do something like this

   private void dgv_ColumnHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
   {
       StudentSorter sorter = null;
       string column = dGV.Columns[e.ColumnIndex].DataPropertyName; //Use column name if you set it
       if (column == "StudentId")
       {
           sorter = new StudentSorter(StudentSorter.SField.StudentId, SetOrderDirection(column));
       }
       else if (column == "Name")
       {
           sorter = new StudentSorter(StudentSorter.SField.Name, SetOrderDirection(column));
       }
   
       ...
   
       List<Student> lstFD = datagridview.DataSource as List<Student>;
       lstFD.Sort(sorter);
       datagridview.DataSource = lstFD;
       datagridview.Refresh();
   }
   

Hope this helps

You can use Task Scheduler Managed Wrapper:

using System;
using Microsoft.Win32.TaskScheduler;

class Program
{
   static void Main(string[] args)
   {
      // Get the service on the local machine
      using (TaskService ts = new TaskService())
      {
         // Create a new task definition and assign properties
         TaskDefinition td = ts.NewTask();
         td.RegistrationInfo.Description = "Does something";

         // Create a trigger that will fire the task at this time every other day
         td.Triggers.Add(new DailyTrigger { DaysInterval = 2 });

         // Create an action that will launch Notepad whenever the trigger fires
         td.Actions.Add(new ExecAction("notepad.exe", "c:\\test.log", null));

         // Register the task in the root folder
         ts.RootFolder.RegisterTaskDefinition(@"Test", td);

         // Remove the task we just created
         ts.RootFolder.DeleteTask("Test");
      }
   }
}

Alternatively you can use native API or go for Quartz.NET. See this for details.

According to pyodbc documentation, connections to the SQL server are not closed by default. Some database drivers do not close connections when close() is called in order to save round-trips to the server.

To close your connection when you call close() you should set pooling to False:

import pyodbc

pyodbc.pooling = False

I resolved my problem on ubunto 20.4 by reinstalling php-mysql.

Remove php-mysql:

sudo apt purge php7.2-mysql

Then install php-mysql:

sudo apt install php7.2-mysql

It will add new configurations in php.ini

#FFFFEEE is not a correct color code. Try with #FFFFEE instead.

Just have your view controller register for the UIApplicationWillEnterForegroundNotification notification and react accordingly.

You need to go to the new folder properties > security tab, and give permissions to the SQL user that has rights on the DATA folder from the SQL server installation folder.

        },
        error: function(data) {
            console.log(data);
        }
    });
}

.overlay didn't have a height or width and no content, and you can't hover over display:none.

I instead gave the div the same size and position as .image and changes RGBA value on hover.

http://jsfiddle.net/Zf5am/566/

.image { position: absolute; border: 1px solid black; width: 200px; height: 200px; z-index:1;}
.image img { max-width: 100%; max-height: 100%; }
.overlay { position: absolute; top: 0; left: 0; background:rgba(255,0,0,0); z-index: 200; width:200px; height:200px; }
.overlay:hover { background:rgba(255,0,0,.7); }

I use WinSplit Revolution for the keyboard arrangement capability and I use bblean as a replacement for Explorer. It has multiple workspace capabilities built right in and it allows you to customize it exactly how you want it to look.

This code runs perfect in my project:

profile_image.buildDrawingCache();
Bitmap bmap = profile_image.getDrawingCache();
String encodedImageData = getEncoded64ImageStringFromBitmap(bmap);


public String getEncoded64ImageStringFromBitmap(Bitmap bitmap) {
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(CompressFormat.JPEG, 70, stream);
    byte[] byteFormat = stream.toByteArray();

    // Get the Base64 string
    String imgString = Base64.encodeToString(byteFormat, Base64.NO_WRAP);

    return imgString;
}

From the official MySQL documentation at https://dev.mysql.com/doc/refman/8.0/en/create-table-foreign-keys.html:

MySQL requires indexes on foreign keys and referenced keys so that foreign key checks can be fast and not require a table scan.

Update 2016

As this answer receives some attention, I want to hint to a more recommended way on doing this using Virtual Hosts: Apache: Redirect SSL

<VirtualHost *:80>
   ServerName mysite.example.com
   Redirect permanent / https://mysite.example.com/
</VirtualHost>

<VirtualHost _default_:443>
   ServerName mysite.example.com
   DocumentRoot /usr/local/apache2/htdocs
   SSLEngine On
# etc...
</VirtualHost>

Old answer, hacky thing given that your ssl-port is not set to 80, this will work:

RewriteEngine on

# force ssl
RewriteCond     %{SERVER_PORT} ^80$
RewriteRule     ^(.*)$ https://%{SERVER_NAME}%{REQUEST_URI} [L,R]

Note that this should be your first rewrite rule.

Edit: This code does the following. The RewriteCond(ition) checks wether the ServerPort of the request is 80 (which is the default http-port, if you specified another port, you would have to adjust the condition to it). If so, we match the whole url (.*) and redirect it to a https-url. %{SERVER_NAME} may be replaced with a specific url, but this way you don't have to alter the code for other projects. %{REQUEST_URI} is the portion of the url after the TLD (top-level-domain), so you will be redirected to where you came from, but as https.

You need a dict:

my_dict = {'cheese': 'cake'}

Example code (from the docs):

>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True

You can read more about dictionaries here.

I think I have figured it out, is it right?:

mysql_query("START TRANSACTION");

$a1 = mysql_query("INSERT INTO rarara (l_id) VALUES('1')");
$a2 = mysql_query("INSERT INTO rarara (l_id) VALUES('2')");

if ($a1 and $a2) {
    mysql_query("COMMIT");
} else {        
    mysql_query("ROLLBACK");
}

DECLARE @Str varchar(500)

SELECT @Str=COALESCE(@Str,'') + CAST(ID as varchar(10)) + ','
FROM dbo.fcUser

SELECT @Str

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):

letsago = "ID" + str(self.dirDesc.values())

However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:

>>>str({'a':1}.values())
'dict_values([1])'

If you REALLY needed to find the variable this way, you could use the eval function:

>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'

or the globals function:

class Foo(object):
    def __init__(self):
        super(Foo, self).__init__()
    def test(self, name):
        print(globals()[name])

foo = Foo()
bar = 'Hello World!'
foo.text('bar')

However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.

git fetch origin
git reset --hard origin/master
git pull

Explanation:

• Fetch will download everything from another repository, in this case, the one marked as "origin".
• Reset will discard changes and revert to the mentioned branch, "master" in repository "origin".
• Pull will just get everything from a remote repository and integrate.

See documentation at http://git-scm.com/docs.

when you define the class A, in A.h, you explicitely say that the class has a member B.

You MUST include "B.h" in "A.h"

The opposite of read is show.

Prelude> show 3
"3"

Prelude> read $ show 3 :: Int

A sub class is a small file of a program that extends from some other class. For example you make a class about cars in general and have basic information that holds true for all cars with your constructors and stuff then you have a class that extends from that on a more specific car or line of cars that would have new variables/methods. I see you already have plenty of examples of code from above by the time I get to post this but I hope this description helps.

As the other answers said, the function you need is cv2.rectangle(), but keep in mind that the coordinates for the bounding box vertices need to be integers if they are in a tuple, and they need to be in the order of (left, top) and (right, bottom). Or, equivalently, (xmin, ymin) and (xmax, ymax).

Current C++

Starting with C++11, there's a std::to_string function overloaded for integer types, so you can use code like:

int a = 20;
std::string s = std::to_string(a);
// or: auto s = std::to_string(a);

The standard defines these as being equivalent to doing the conversion with sprintf (using the conversion specifier that matches the supplied type of object, such as %d for int), into a buffer of sufficient size, then creating an std::string of the contents of that buffer.

Old C++

For older (pre-C++11) compilers, probably the most common easy way wraps essentially your second choice into a template that's usually named lexical_cast, such as the one in Boost, so your code looks like this:

int a = 10;
string s = lexical_cast<string>(a);

One nicety of this is that it supports other casts as well (e.g., in the opposite direction works just as well).

Also note that although Boost lexical_cast started out as just writing to a stringstream, then extracting back out of the stream, it now has a couple of additions. First of all, specializations for quite a few types have been added, so for many common types, it's substantially faster than using a stringstream. Second, it now checks the result, so (for example) if you convert from a string to an int, it can throw an exception if the string contains something that couldn't be converted to an int (e.g., 1234 would succeed, but 123abc would throw).

String is immutable for several reasons, here is a summary:

• Security: parameters are typically represented as String in network connections, database connection urls, usernames/passwords etc. If it were mutable, these parameters could be easily changed.
• Synchronization and concurrency: making String immutable automatically makes them thread safe thereby solving the synchronization issues.
• Caching: when compiler optimizes your String objects, it sees that if two objects have same value (a="test", and b="test") and thus you need only one string object (for both a and b, these two will point to the same object).
• Class loading: String is used as arguments for class loading. If mutable, it could result in wrong class being loaded (because mutable objects change their state).

That being said, immutability of String only means you cannot change it using its public API. You can in fact bypass the normal API using reflection. See the answer here.

In your example, if String was mutable, then consider the following example:

  String a="stack";
  System.out.println(a);//prints stack
  a.setValue("overflow");
  System.out.println(a);//if mutable it would print overflow

If you have SublimeLinter installed, your theme (at least it ST3) may end up in .../Packages/User/SublimeLinter/[ your-chosen-theme ]

As mentioned above - find the nested 'settings' dict and edit or add the 'lineHighlight' entry with your desired #RRGGBB or #RRGGBBAA. I like #0000AA99 when on a black(ish) background.

Handy tool if you do not know your color combinations: RGBtoHEX and HEXtoRGB

You need #include<string> to use string AND #include<iostream> to use cin and cout. (I didn't get it when I read the answers). Here's some code which works:

#include<string>
#include<iostream>
using namespace std;

int main()
{
    string name;
    cin >> name;
    string message("hi");
    cout << name << message;
    return 0;
}

For the 24-hour time, you need to use HH24 instead of HH.

For the 12-hour time, the AM/PM indicator is written as A.M. (if you want periods in the result) or AM (if you don't). For example:

SELECT invoice_date,
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH24:MI:SS') "Date 24Hr",
       TO_CHAR(invoice_date, 'DD-MM-YYYY HH:MI:SS AM') "Date 12Hr"
  FROM invoices
;

For more information on the format models you can use with TO_CHAR on a date, see http://docs.oracle.com/cd/E16655_01/server.121/e17750/ch4datetime.htm#NLSPG004.

FYI I did a little research as well and if the name of the font-family you want to apply contains spaces (as an example I take Gill Alt One MT Light), you should write it this way :

strbody= "<BODY style=" & Chr(34) & "font-family:Gill Alt One MT Light" & Chr(34) & ">" & YOUR_TEXT & "</BODY>"

            public ActionResult Index()
            {
                return View();
            }


            public ActionResult Test(string Name)
            {
                return RedirectToAction("Index");
            }

Return View Directly displays your view but

Redirect ToAction Action is performed

Make all the checkboxes required and add a change listener. If any one checkbox is ticked, remove required attribute from all the checkboxes. Below is a sample code.

<div class="form-group browsers">
    <label class="control-label col-md-4" for="optiontext">Select an option</label>
    <div class="col-md-6">
        <input type="checkbox" name="browser" value="Chrome" required/> Google Chrome<br>
        <input type="checkbox" name="browser" value="IE" required/> Internet Explorer<br>
        <input type="checkbox" name="browser" value="Mozilla" required/> Mozilla Firefox<br>
        <input type="checkbox" name="browser" value="Edge" required/> Microsoft Edge
    </div>
</div>

Change listener :

$(function(){
    var requiredCheckboxes = $('.browsers :checkbox[required]');
    requiredCheckboxes.change(function(){
        if(requiredCheckboxes.is(':checked')) {
            requiredCheckboxes.removeAttr('required');
        } else {
            requiredCheckboxes.attr('required', 'required');
        }
    });
});

When Atom auto-indent-detection got it hopelessly wrong and refused to let me type a literal Tab character, I eventually found the 'Force-Tab' extension - which gave me back control. I wanted to keep shift-tab for outdenting, so set ctrl-tab to insert a hard tab. In my keymap I added:

'atom-text-editor': 'ctrl-tab': 'force-tab:insert-actual-tab'

Use this code:

 HttpContext.Current.Server.MapPath("~")

Detailed Reference:

Server.MapPath specifies the relative or virtual path to map to a physical directory.

• Server.MapPath(".") returns the current physical directory of the file (e.g. aspx) being executed
• Server.MapPath("..") returns the parent directory
• Server.MapPath("~") returns the physical path to the root of the application
• Server.MapPath("/") returns the physical path to the root of the domain name (is not necessarily the same as the root of the application)

An example:

Let's say you pointed a web site application (http://www.example.com/) to

C:\Inetpub\wwwroot

and installed your shop application (sub web as virtual directory in IIS, marked as application) in

D:\WebApps\shop

For example, if you call Server.MapPath in following request:

http://www.example.com/shop/products/GetProduct.aspx?id=2342

then:

Server.MapPath(".") returns D:\WebApps\shop\products
Server.MapPath("..") returns D:\WebApps\shop
Server.MapPath("~") returns D:\WebApps\shop
Server.MapPath("/") returns C:\Inetpub\wwwroot
Server.MapPath("/shop") returns D:\WebApps\shop

If Path starts with either a forward (/) or backward slash (), the MapPath method returns a path as if Path were a full, virtual path.

If Path doesn't start with a slash, the MapPath method returns a path relative to the directory of the request being processed.

Note: in C#, @ is the verbatim literal string operator meaning that the string should be used "as is" and not be processed for escape sequences.

Footnotes

Server.MapPath(null) and Server.MapPath("") will produce this effect too.

I could care less about IE6, as long as it works in IE8, Firefox 4, and Safari 5

This makes me happy.

Try this: Live Demo

display: table is surprisingly good. Once you don't care about IE7, you're free to use it. It doesn't really have any of the usual downsides of <table>.

CSS:

#container {
    background: #ccc;
    display: table
}
#left, #right {
    display: table-cell
}
#left {
    width: 150px;
    background: #f0f;
    border: 5px dotted blue;
}
#right {
    background: #aaa;
    border: 3px solid #000
}

Yes, it's possible to use inline if-expressions:

{{ 'Update' if files else 'Continue' }}

I have found a useful article that also explains the topic quite clearly and easy language. Link is JSONP

Some of the worth noting points are:

1. JSONP pre-dates CORS.
2. It is a pseudo-standard way to retreive data from a different domain,
3. It has limited CORS features (only GET method)

Working is as follows:

1. <script src="url?callback=function_name"> is included in the html code
2. When step 1 gets executed it sens a function with the same function name (as given in the url parameter) as a response.
3. If the function with the given name exists in the code, it will be executed with the data, if any, returned as an argument to that function.

Correct solution with "File" class to get the directory - the "path" of the file:

String path = new File("C:\\Temp\\your directory\\yourfile.txt").getParent();

which will return:

path = "C:\\Temp\\your directory"

I recently came across this problem myself.

<!--Instead of using input-->
<input type="submit"/>
<!--Use button-->
<button type="submit">
<!--You can then attach your custom CSS to the button-->

Hope that helps.

Extracting the title is not difficult, and you have many options, search here on Stack Overflow for "Java HTML parsers". One of them is Jsoup.

You can navigate the page using DOM if you know the page structure, see http://jsoup.org/cookbook/extracting-data/dom-navigation

It's a good library and I've used it in my last projects.

I think the problem may be that you are not finding your element because of the "#" in your call to get it:

window.parent.document.getElementById('#target'); 

You only need the # if you are using jquery. Here it should be:

window.parent.document.getElementById('target'); 

The web.xml file should be listed right below the last line in your screenshot and resides in WebContent/WEB-INF. If it is missing you might have missed to check the "Generate web.xml deployment descriptor" option on the third page of the Dynamic web project wizard.

I recently had the same issue while trying to access domains using CloudFlare Origin CA.

The only way I found to workaround/avoid HSTS cert exception on Chrome (Windows build) was following the short instructions in https://support.opendns.com/entries/66657664.

The workaround:
Add to Chrome shortcut the flag --ignore-certificate-errors, then reopen it and surf to your website.

Reminder:
Use it only for development purposes.

You can pass you session variables from your php script to JQUERY using JSON such as

    colNames:['Actions'], 
    colModel:[{
                name:'Actions',
                index:'Actions', 
                width:155,
                sortable:false
              }], 
    rowNum:30, 
    rowList:[50,100,150,200,300,400,500,600],

Your code only creates a time without a date. If your assumption is correct that when it runs the application.wait the time actually already reached that time it will wait for 24 hours exactly. I also worry a bit about calling now() multiple times (could be different?) I would change the code to

 application.wait DateAdd("s", 1, Now)

They are synonyms, no difference at all.Decimal and Numeric data types are numeric data types with fixed precision and scale.

-- Initialize a variable, give it a data type and an initial value

declare @myvar as decimal(18,8) or numeric(18,8)----- 9 bytes needed

-- Increse that the vaue by 1

set @myvar = 123456.7

--Retrieve that value

select @myvar as myVariable

Solution for safe and high secured encode anyone file in OpenSSL and command-line:

You should have ready some X.509 certificate for encrypt files in PEM format.

Encrypt file:

openssl smime -encrypt -binary -aes-256-cbc -in plainfile.zip -out encrypted.zip.enc -outform DER yourSslCertificate.pem

What is what:

• smime - ssl command for S/MIME utility (smime(1))
• -encrypt - chosen method for file process
• -binary - use safe file process. Normally the input message is converted to "canonical" format as required by the S/MIME specification, this switch disable it. It is necessary for all binary files (like a images, sounds, ZIP archives).
• -aes-256-cbc - chosen cipher AES in 256 bit for encryption (strong). If not specified 40 bit RC2 is used (very weak). (Supported ciphers)
• -in plainfile.zip - input file name
• -out encrypted.zip.enc - output file name
• -outform DER - encode output file as binary. If is not specified, file is encoded by base64 and file size will be increased by 30%.
• yourSslCertificate.pem - file name of your certificate's. That should be in PEM format.

That command can very effectively a strongly encrypt big files regardless of its format.
Known issue: Something wrong happens when you try encrypt huge file (>600MB). No error thrown, but encrypted file will be corrupted. Always verify each file! (or use PGP - that has bigger support for files encryption with public key)

Decrypt file:

openssl smime -decrypt -binary -in encrypted.zip.enc -inform DER -out decrypted.zip -inkey private.key -passin pass:your_password

What is what:

• -inform DER - same as -outform above
• -inkey private.key - file name of your private key. That should be in PEM format and can be encrypted by password.
• -passin pass:your_password - your password for private key encrypt. (passphrase arguments)

It's never wise to rely on defaults being set to a particular value, IMHO, whether it's for date formats, currency formats, optimiser modes or whatever. You should always set the value of date format that you need, in the server, the client, or the application.

In particular, never rely on defaults when converting date or numeric data types for display purposes, because a single change to the database can break your application. Always use an explicit conversion format. For years I worked on Oracle systems where the out of the box default date display format was MM/DD/RR, which drove me nuts but at least forced me to always use an explicit conversion.

With nginx you can send both tokens like this (even though it's against the standard):

Authorization: Basic basic-token,Bearer bearer-token

This works as long as the basic token is first - nginx successfully forwards it to the application server.

And then you need to make sure your application can properly extract the Bearer from the above string.

Just add position, right and top to your class .close-image

.close-image {
    cursor: pointer;
    display: block;
    float: right;  
    z-index: 3;
    position: absolute; /*newly added*/
    right: 5px; /*newly added*/
    top: 5px;/*newly added*/
}

You can't: It's a security feature in all modern browsers.

For IE8, it's off by default, but can be reactivated using a security setting:

When a file is selected by using the input type=file object, the value of the value property depends on the value of the "Include local directory path when uploading files to a server" security setting for the security zone used to display the Web page containing the input object.

The fully qualified filename of the selected file is returned only when this setting is enabled. When the setting is disabled, Internet Explorer 8 replaces the local drive and directory path with the string C:\fakepath\ in order to prevent inappropriate information disclosure.

In all other current mainstream browsers I know of, it is also turned off. The file name is the best you can get.

More detailed info and good links in this question. It refers to getting the value server-side, but the issue is the same in JavaScript before the form's submission.

I guess I'm unclear about what the OP was really asking for... Do you want to pass the whole array/list and operate on it inside the function? Or do you want the same thing done on every value/item in the array/list. If the latter is what you wish I have found a method which works well.

I'm more familiar with programming languages such as Fortran and C, in which you can define elemental functions which operate on each element inside an array. I finally tracked down the python equivalent to this and thought I would repost the solution here. The key is to 'vectorize' the function. Here is an example:

def myfunc(a,b):
    if (a>b): return a
    else: return b
vecfunc = np.vectorize(myfunc)
result=vecfunc([[1,2,3],[5,6,9]],[7,4,5])
print(result)

Output:

[[7 4 5]
 [7 6 9]]

When you drag a custom framework into a project under Xcode 10.1, it assumes that the framework is a system framework and puts the framework into "Link Binary With Libraries" section of "Build Phases" under your target.

System frameworks are already on the device so it is not copied over to the device and thus cannot execute at runtime so KABOOM (crash in __abort_with_payload, and disinforming error: "Reason: image not found"). This is because the framework code is not copied to the device...

In reality, to have Xcode both link the custom framework and ensure that it is copied along with your code to the iOS device (real or simulator) the custom framework needs to be moved to "Copy Bundle Resources". This ultimately packages the framework along with your code executable to be available on the device together.

To add a custom framework to a project and avoid the Apple crash:

1. Drag custom framework into your iOS project file list
2. Click ProjectName in Navigator -> TargetName -> "Build Phases" -> Link Binary With Libraries disclosure triangle
3. Drag custom framework out and down to "Copy Bundle Resources" section below (Xcode now moves the framework reference, fixed in Xcode 10)
4. Run in simulator or device

The custom framework thus gets copied along with your code to your target device and is available at runtime.

[editorial: you would think Xcode would be smart enough to figure out the difference between one of it's system frameworks which need not be copied to the device and a custom framework that is, oh I don't know, in the project root directory hierarchy... ]

After much further research, i managed to find a solution.

google.maps.event.addListener(map, 'click', function(event) {
   placeMarker(event.latLng);
});

function placeMarker(location) {
    var marker = new google.maps.Marker({
        position: location, 
        map: map
    });
}

A Simply Swift,

Step 1: Create One SubClass of UITableViewCell
Step 2: Add this method to SubClass of UITableViewCell

override func layoutSubviews() {
    super.layoutSubviews()
    self.imageView?.frame = CGRectMake(0, 0, 10, 10)
}

Step 3: Create cell object using that SubClass in cellForRowAtIndexPath,

Ex: let customCell:CustomCell = CustomCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")

Step 4: Enjoy

I prefer to use <limits> to check for an int until it is passed.

#include <iostream>
#include <limits> //std::numeric_limits

using std::cout, std::endl, std::cin;

int main() {
    int num;
    while(!(cin >> num)){  //check the Input format for integer the right way
        cin.clear();
        cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
        cout << "Invalid input.  Reenter the number: ";
      };

    cout << "output= " << num << endl;

    return 0;
}

Try to use an XPath expression for searching the element and then, the following code works:

driver.findElement(By.xpath(".//*[@id='txtFilterContentUnit']")).sendKeys(Keys.ENTER);

This snippet is from working code.

You can trigger bat file not only from Windows GUI or Task Scheduler, but directly from PHP script when you need it. But in most cases it will have execution for 30-60 sec. depending from your PHP configuration. If job in BAT file is long and you don't want to freeze your PHP scripts, you need to fork BAT job as another process using php.exe and not be dependable from Apache.

This runs in background mode in Windows, seen as separate processes cmd.exe and php.exe from Task Manager not halting your Apache PHP scripts. The messages produced by your script may be stored and retrieved back via log files.

In my case in file_scanner.php I do some heavy calculations in loop for big array of files which may last for few hours with php function sleep() not to overload CPU.

The success poiner result from file $r which you can query via ajax if you want to know success or fauty start. In my case file_scanner.php writes log file with messages somefile.jpg - OK wich you can load to your UI with AJAX every few seconds to show progress.

The answer by Kleist certainly works, but there is an important caveat:

When you write a Makefile manually, you might generate a SRCS variable using a function to select all .cpp and .h files. If a source file is later added, re-running make will include it.

However, CMake (with a command like file(GLOB ...)) will explicitly generate a file list and place it in the auto-generated Makefile. If you have a new source file, you will need to re-generate the Makefile by re-running cmake.

edit: No need to remove the Makefile.

This should do the trick

public static IEnumerable<T> FindVisualChildren<T>(DependencyObject depObj) where T : DependencyObject
{
    if (depObj != null)
    {
        for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++)
        {
            DependencyObject child = VisualTreeHelper.GetChild(depObj, i);
            if (child != null && child is T)
            {
                yield return (T)child;
            }

            foreach (T childOfChild in FindVisualChildren<T>(child))
            {
                yield return childOfChild;
            }
        }
    }
}

then you enumerate over the controls like so

foreach (TextBlock tb in FindVisualChildren<TextBlock>(window))
{
    // do something with tb here
}

Bonus exercise response. The simple solution. Obviously in a real implementation one might wrap this or something to avoid requiring the user to include height in their response.

IsHeightBalanced(tree, out height)
    if (tree is empty)
        height = 0
        return true
    balance = IsHeightBalanced(tree.left, heightleft) and IsHeightBalanced(tree.right, heightright)
    height = max(heightleft, heightright)+1
    return balance and abs(heightleft - heightright) <= 1     

I had this problem with chrome when I was working on a WordPress site. I added this code

$_SERVER['HTTPS'] = false;

into the theme's functions.php file - it asks you to log in again when you save the file but once it's logged in it works straight away.

For TamperMonkey:

#include <iostream>

class bar
{
public:
  bar()
  {
    std::cout << "bar() called" << std::endl;
  }

  ~bar()
  {
    std::cout << "~bar() called" << std::endl;

  }
};
class foo
{
public:
  foo()
    : b(new bar())
  {
    std::cout << "foo() called" << std::endl;
    throw "throw something";
  }

  ~foo()
  {
    delete b;
    std::cout << "~foo() called" << std::endl;
  }

private:
  bar *b;
};


int main(void)
{
  try {
    std::cout << "heap: new foo" << std::endl;
    foo *f = new foo();
  } catch (const char *e) {
    std::cout << "heap exception: " << e << std::endl;
  }

  try {
    std::cout << "stack: foo" << std::endl;
    foo f;
  } catch (const char *e) {
    std::cout << "stack exception: " << e << std::endl;
  }

  return 0;
}

the output:

heap: new foo
bar() called
foo() called
heap exception: throw something
stack: foo
bar() called
foo() called
stack exception: throw something

the destructors are not called, so if a exception need to be thrown in a constructor, a lot of stuff(e.g. clean up?) to do.

Working solution without access token as of October-14-2018:

Search for the username:

https://www.instagram.com/web/search/topsearch/?query=<username>

Example:

https://www.instagram.com/web/search/topsearch/?query=therock

This is a search query. Find the exact matched entry in the reply and get user ID from the entry.

#1 I use the last one frequently when having buttons on the layout which are not generated (but static obviously).

If you use it in practice and in a business application, pay extra attention here, because when you use source obfuscater like ProGuard, you'll need to mark these methods in your activity as to not be obfuscated.

For archiving some kind of compile-time-security with this approach, have a look at Android Lint (example).

#2 Pros and cons for all methods are almost the same and the lesson should be:

Use what ever is most appropriate or feels most intuitive to you.

If you have to assign the same OnClickListener to multiple button instances, save it in the class-scope (#1). If you need a simple listener for a Button, make an anonymous implementation:

button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        // Take action.
    }
});

I tend to not implement the OnClickListener in the activity, this gets a little confusing from time to time (especially when you implement multiple other event-handlers and nobody knows what this is all doing).

You can download ChromeDriver here: https://sites.google.com/a/chromium.org/chromedriver/downloads

Then you have multiple options:

• add it to your system path
• put it in the same directory as your python script

• specify the location directly via executable_path

  driver = webdriver.Chrome(executable_path='C:/path/to/chromedriver.exe')
  

Here is my solution for setting the ActionBar title from fragments, when using NavigationDrawer. This solution uses an Interface so the fragments does not need to reference the parent Activity directly:

1) Create an Interface:

public interface ActionBarTitleSetter {
    public void setTitle(String title); 
}

2) In the Fragment's onAttach, cast the activity to the Interface type and call the SetActivityTitle method:

@Override 
public void onAttach(Activity activity) { 
    super.onAttach(activity);
    ((ActionBarTitleSetter) activity).setTitle(getString(R.string.title_bubbles_map)); 
}

3) In the activity, implement the ActionBarTitleSetter interface:

@Override 
public void setTitle(String title) { 
    mTitle = title; 
}

If you want to rename a single column and keep the rest as it is:

from pyspark.sql.functions import col
new_df = old_df.select(*[col(s).alias(new_name) if s == column_to_change else s for s in old_df.columns])

                try {

                while (rowIterator.hasNext()) {
                    Row row = rowIterator.next();

                        case Cell.CELL_TYPE_STRING:
                            System.out.print(cell.getStringCellValue());
                            break;
                        case Cell.CELL_TYPE_BOOLEAN:
                            System.out.print(cell.getBooleanCellValue());
                            break;
                        case Cell.CELL_TYPE_NUMERIC:

                            break;
                        }
                        System.out.print(" - ");
                    }
                    System.out.println();
                }
            }

My solution is try to using a boolean variable :

public class Blocker {
    private static final int DEFAULT_BLOCK_TIME = 1000;
    private boolean mIsBlockClick;

    /**
     * Block any event occurs in 1000 millisecond to prevent spam action
     * @return false if not in block state, otherwise return true.
     */
    public boolean block(int blockInMillis) {
        if (!mIsBlockClick) {
            mIsBlockClick = true;
            new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    mIsBlockClick = false;
                }
            }, blockInMillis);
            return false;
        }
        return true;
    }

    public boolean block() {
        return block(DEFAULT_BLOCK_TIME);
    }
}

And using as below:

view.setOnClickListener(new View.OnClickListener() {
            private Blocker mBlocker = new Blocker();

            @Override
            public void onClick(View v) {
                if (!mBlocker.block(block-Time-In-Millis)) {
                    // do your action   
                }
            }
        });

UPDATE: Kotlin solution, using view extension

fun View.safeClick(listener: View.OnClickListener, blockInMillis: Long = 500) {
    var lastClickTime: Long = 0
    this.setOnClickListener {
        if (SystemClock.elapsedRealtime() - lastClickTime < blockInMillis) return@setOnClickListener
        lastClickTime = SystemClock.elapsedRealtime()
        listener.onClick(this)
    }
}

Can't you import it as a git project and then (if you have the m2eclipse installed) right click on the project in the Package Explorer > Maven > Enable Dependency Management?

I didn't want to unstack or over-complicate this issue, since I just wanted to drop some highly correlated features as part of a feature selection phase.

So I ended up with the following simplified solution:

# map features to their absolute correlation values
corr = features.corr().abs()

# set equality (self correlation) as zero
corr[corr == 1] = 0

# of each feature, find the max correlation
# and sort the resulting array in ascending order
corr_cols = corr.max().sort_values(ascending=False)

# display the highly correlated features
display(corr_cols[corr_cols > 0.8])

In this case, if you want to drop correlated features, you may map through the filtered corr_cols array and remove the odd-indexed (or even-indexed) ones.

Basic counting is done as was stated in other answers, and in the pig documentation:

logs = LOAD 'log';
all_logs_in_a_bag = GROUP logs ALL;
log_count = FOREACH all_logs_in_a_bag GENERATE COUNT(logs);
dump log_count

You are right that counting is inefficient, even when using pig's builtin COUNT because this will use one reducer. However, I had a revelation today that one of the ways to speed it up would be to reduce the RAM utilization of the relation we're counting.

In other words, when counting a relation, we don't actually care about the data itself so let's use as little RAM as possible. You were on the right track with your first iteration of the count script.

logs = LOAD 'log'
ones = FOREACH logs GENERATE 1 AS one:int;
counter_group = GROUP ones ALL;
log_count = FOREACH counter_group GENERATE COUNT(ones);
dump log_count

This will work on much larger relations than the previous script and should be much faster. The main difference between this and your original script is that we don't need to sum anything.

This also doesn't have the same problem as other solutions where null values would impact the count. This will count all the rows, regardless of if the first column is null or not.

$('input:radio[checked=false]');

this will also work

input:radio:not(:checked)

or

:radio:not(:checked)

A late answer, although I thought of giving an in-depth answer to this question. This method is suitable for Android Studio 1.0.0 and above.

STEPS

1. First switch your folder structure from Android to Project.

2. Now search for the libs folder inside app - build folder.

3. Once you have pasted the .jar file inside libs folder. Right click on the jar file and at end click on Add as library. This will take care of adding compile files('libs/library_name.jar') in build.gradle [You don't have to manually enter this in your build file].

Now you can start using the library in your project.

If your iframe is in the same domain as your parent page you can access the elements using document.frames collection.

// replace myIFrame with your iFrame id
// replace myIFrameElemId with your iFrame's element id
// you can work on document.frames['myIFrame'].document like you are working on
// normal document object in JS
window.frames['myIFrame'].document.getElementById('myIFrameElemId')

If your iframe is not in the same domain the browser should prevent such access for security reasons.

Thanks for the solution !

It works, but in a french Excel environment, you should apply something like

TEXTE(F2;"jj/mm/aaaa")

to get the date preserved as it is displayed in F2 cell, after concatenation. Best Regards

Java generics uses type erasure. The bit in the angle brackets (<Integer> and <String>) gets removed, so you'd end up with two methods that have an identical signature (the add(Set) you see in the error). That's not allowed because the runtime wouldn't know which to use for each case.

If Java ever gets reified generics, then you could do this, but that's probably unlikely now.

Yes, you can do this. The knack you need is the concept that there are two ways of getting tables out of the table server. One way is ..

FROM TABLE A

The other way is

FROM (SELECT col as name1, col2 as name2 FROM ...) B

Notice that the select clause and the parentheses around it are a table, a virtual table.

So, using your second code example (I am guessing at the columns you are hoping to retrieve here):

SELECT a.attr, b.id, b.trans, b.lang
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, a.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)

Notice that your real table attribute is the first table in this join, and that this virtual table I've called b is the second table.

This technique comes in especially handy when the virtual table is a summary table of some kind. e.g.

SELECT a.attr, b.id, b.trans, b.lang, c.langcount
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, at.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)
JOIN (
 SELECT count(*) AS langcount,  at.attribute
 FROM attributeTranslation at
 GROUP BY at.attribute
) c ON (a.id = c.attribute)

See how that goes? You've generated a virtual table c containing two columns, joined it to the other two, used one of the columns for the ON clause, and returned the other as a column in your result set.

This is possible with CSS3. Just use position: sticky, as seen here.

position: -webkit-sticky; /* Safari & IE */
position: sticky;
top: 0;

It 'a permission problem when IIS is running I had this problem and I solved it in this way

I went on folders

C:\Windows\ System32\config\SystemProfile

and

C:\Windows\SysWOW64\config\SystemProfile

are protected system folders, they usually have the lock.

Right-click-> Card security-> Click on Edit-> Add untente "Autenticadet User" and assign permissions.

At this point everything is solved, if you still have problems try to give all permissions to "Everyone"

You are correct that storing the password in a plain-text field is a horrible idea. However, as far as location goes, for most of the cases you're going to encounter (and I honestly can't think of any counter-examples) storing the representation of a password in the database is the proper thing to do. By representation I mean that you want to hash the password using a salt (which should be different for every user) and a secure 1-way algorithm and store that, throwing away the original password. Then, when you want to verify a password, you hash the value (using the same hashing algorithm and salt) and compare it to the hashed value in the database.

So, while it is a good thing you are thinking about this and it is a good question, this is actually a duplicate of these questions (at least):

• How to best store user information and user login and password
• Best practices for storing database passwords
• Salting Your Password: Best Practices?
• Is it ever ok to store password in plain text in a php variable or php constant?

To clarify a bit further on the salting bit, the danger with simply hashing a password and storing that is that if a trespasser gets a hold of your database, they can still use what are known as rainbow tables to be able to "decrypt" the password (at least those that show up in the rainbow table). To get around this, developers add a salt to passwords which, when properly done, makes rainbow attacks simply infeasible to do. Do note that a common misconception is to simply add the same unique and long string to all passwords; while this is not horrible, it is best to add unique salts to every password. Read this for more.

Ok, at that time got it done with the help of a friend and the code looks like this.

Sub Saving()

Dim part1 As String

Dim part2 As String


part1 = Range("C5").Value

part2 = Range("C8").Value


ActiveWorkbook.SaveAs Filename:= _

"C:\-docs\cmat\Desktop\pieteikumi\" & part1 & " " & part2 & ".xlsm", FileFormat:= _
xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False

End Sub

How do I edit this part (FileFormat:= _ xlOpenXMLWorkbookMacroEnabled) for it to save as Excel 97-2013 Workbook, have tried several variations with no success. Thankyou

Seems, that I found the solution, but my idea is flawed. By doing this FileFormat:= _ xlOpenXMLWorkbook, it drops out a popup saying, the you cannot save this workbook as a file without Macro enabled. So, is this impossible?

In general you can concatenate a whole sequence of arrays along any axis:

numpy.concatenate( LIST, axis=0 )

but you do have to worry about the shape and dimensionality of each array in the list (for a 2-dimensional 3x5 output, you need to ensure that they are all 2-dimensional n-by-5 arrays already). If you want to concatenate 1-dimensional arrays as the rows of a 2-dimensional output, you need to expand their dimensionality.

As Jorge's answer points out, there is also the function stack, introduced in numpy 1.10:

numpy.stack( LIST, axis=0 )

This takes the complementary approach: it creates a new view of each input array and adds an extra dimension (in this case, on the left, so each n-element 1D array becomes a 1-by-n 2D array) before concatenating. It will only work if all the input arrays have the same shape—even along the axis of concatenation.

vstack (or equivalently row_stack) is often an easier-to-use solution because it will take a sequence of 1- and/or 2-dimensional arrays and expand the dimensionality automatically where necessary and only where necessary, before concatenating the whole list together. Where a new dimension is required, it is added on the left. Again, you can concatenate a whole list at once without needing to iterate:

numpy.vstack( LIST )

This flexible behavior is also exhibited by the syntactic shortcut numpy.r_[ array1, ...., arrayN ] (note the square brackets). This is good for concatenating a few explicitly-named arrays but is no good for your situation because this syntax will not accept a sequence of arrays, like your LIST.

There is also an analogous function column_stack and shortcut c_[...], for horizontal (column-wise) stacking, as well as an almost-analogous function hstack—although for some reason the latter is less flexible (it is stricter about input arrays' dimensionality, and tries to concatenate 1-D arrays end-to-end instead of treating them as columns).

Finally, in the specific case of vertical stacking of 1-D arrays, the following also works:

numpy.array( LIST )

...because arrays can be constructed out of a sequence of other arrays, adding a new dimension to the beginning.

I know this is old but here's a one liner list comprehension:

data = ['word1, 23, 12','word2, 10, 19','word3, 11, 15']

[[int(item) if item.isdigit() else item for item in items.split(', ')] for items in data]

or

[int(item) if item.isdigit() else item for items in data for item in items.split(', ')]

You can use the required html attribute if you want:

@Html.TextBoxFor(m => m.ShortName, 
new { @class = "form-control", placeholder = "short name", required="required"})

or you can use the RequiredAttribute class in .Net. With jQuery the RequiredAttribute can Validate on the front end and server side. If you want to go the MVC route, I'd suggest reading Data annotations MVC3 Required attribute.

OR

You can get really advanced:

@{
  // if you aren't using UnobtrusiveValidation, don't pass anything to this constructor
  var attributes = new Dictionary<string, object>(
    Html.GetUnobtrusiveValidationAttributes(ViewData.TemplateInfo.HtmlFieldPrefix));

 attributes.Add("class", "form-control");
 attributes.Add("placeholder", "short name");

  if (ViewData.ModelMetadata.ContainerType
      .GetProperty(ViewData.ModelMetadata.PropertyName)
      .GetCustomAttributes(typeof(RequiredAttribute), true)
      .Select(a => a as RequiredAttribute)
      .Any(a => a != null))
  {
   attributes.Add("required", "required");
  }

  @Html.TextBoxFor(m => m.ShortName, attributes)

}

or if you need it for multiple editor templates:

public static class ViewPageExtensions
{
  public static IDictionary<string, object> GetAttributes(this WebViewPage instance)
  {
    // if you aren't using UnobtrusiveValidation, don't pass anything to this constructor
    var attributes = new Dictionary<string, object>(
      instance.Html.GetUnobtrusiveValidationAttributes(
         instance.ViewData.TemplateInfo.HtmlFieldPrefix));

    if (ViewData.ModelMetadata.ContainerType
      .GetProperty(ViewData.ModelMetadata.PropertyName)
      .GetCustomAttributes(typeof(RequiredAttribute), true)
      .Select(a => a as RequiredAttribute)
      .Any(a => a != null))
    {
      attributes.Add("required", "required");
    }
  }
}

then in your templates:

@{
  // if you aren't using UnobtrusiveValidation, don't pass anything to this constructor
  var attributes = this.GetAttributes();

  attributes.Add("class", "form-control");
  attributes.Add("placeholder", "short name");

  @Html.TextBoxFor(m => m.ShortName, attributes)

}

Update 1 (for Tomas who is unfamilar with ViewData).

What's the difference between ViewData and ViewBag?

Excerpt:

So basically it (ViewBag) replaces magic strings:

ViewData["Foo"]

with magic properties:

ViewBag.Foo

Use a loop on the split values

string values = "0,1,2,3,4,5,6,7,8,9";

foreach(string value in values.split(','))
{
    //do something with individual value
}

Less text is required with this approach:

ls -r | ? {$_.mode -match "d"}

select
    email 
from loginuser where
patindex ('%[ &'',":;!+=\/()<>]*%', email) > 0  -- Invalid characters
or patindex ('[@.-_]%', email) > 0   -- Valid but cannot be starting character
or patindex ('%[@.-_]', email) > 0   -- Valid but cannot be ending character
or email not like '%@%.%'   -- Must contain at least one @ and one .
or email like '%..%'        -- Cannot have two periods in a row

or email like '%.cm' or email like '%.co' -- Unlikely. Probably typos

This worked for me. Had to apply rtrim and ltrim to avoid false positives.

There's many different ways to go about this, but I'm partial to describeBy in the psych package:

describeBy(df$dt, df$group, mat = TRUE) 

A simple [Fragment] subclass.
Kotlin!
contextA - is a parent (main) Activity. Set it on create object.

class Start(contextA: Context) : Fragment() {

var contextB: Context = contextA;

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    // Inflate the layout for this fragment
    val fl = inflater.inflate(R.layout.fragment_start, container, false)

    // only thet variant is worked on me
    fl.button.setOnClickListener { view -> openPogodaUrl(view) }

    return fl;
}

fun openPogodaUrl(view: View) {        
    try {
        pogoda.webViewClient = object : WebViewClient() { // pogoda - is a WebView
            override fun shouldOverrideUrlLoading(view: WebView?, url: String?): Boolean {
                view?.loadUrl(url)
                return true
            }
        }
        pogoda.loadUrl("http://exemple.com/app_vidgets/pogoda.html");
    }
    catch (e: Exception)
    {
        Toast.makeText(contextB, e.toString(), Toast.LENGTH_LONG).show();
    }
}

}

Adding for completeness of the answers: preloading with HTML

<link rel="preload" href="bg-image-wide.png" as="image">

Other preloading features exist, but none are quite as fit for purpose as <link rel="preload">:

• <link rel="prefetch"> has been supported in browsers for a long time, but it is intended for prefetching resources that will be used in the next navigation/page load (e.g. when you go to the next page). This is fine, but isn't useful for the current page! In addition, browsers will give prefetch resources a lower priority than preload ones — the current page is more important than the next. See Link prefetching FAQ for more details.
• <link rel="prerender"> renders a specified webpage in the background, speeding up its load if the user navigates to it. Because of the potential to waste users bandwidth, Chrome treats prerender as a NoState prefetch instead.
• <link rel="subresource"> was supported in Chrome a while ago, and was intended to tackle the same issue as preload, but it had a problem: there was no way to work out a priority for the items (as didn't exist back then), so they all got fetched with fairly low priority.

There are a number of script-based resource loaders out there, but they don't have any power over the browser's fetch prioritization queue, and are subject to much the same performance problems.

You do not require jQuery for this, simply use the following CSS content:

li {cursor: pointer}

And voilà! Handy.

I have not tried this, so I am not guarantueeing anything, however

foreach Bar f in filterBars
{
     search(f)
}
Foo search(Bar b)
{
    fooSelect = (from f in fooBunch
                 where !(from b in f.BarList select b.BarId).Contains(b.ID)
                 select f).ToList();

    return fooSelect;
}

The trick is to

1. create a CNAME for www.myapp.com to myapp.heroku.com
2. create a 301 redirection from myapp.com to www.myapp.com

os.system() returns the (encoded) process exit value. 0 means success:

On Unix, the return value is the exit status of the process encoded in the format specified for wait(). Note that POSIX does not specify the meaning of the return value of the C system() function, so the return value of the Python function is system-dependent.

The output you see is written to stdout, so your console or terminal, and not returned to the Python caller.

If you wanted to capture stdout, use subprocess.check_output() instead:

x = subprocess.check_output(['whoami'])

Is it essential that you need a NumPy array? Otherwise you could speed things up by loading the data as a nested list.

def load(fname):
    ''' Load the file using std open'''
    f = open(fname,'r')

    data = []
    for line in f.readlines():
        data.append(line.replace('\n','').split(' '))

    f.close()

    return data

For a text file with 4000x4000 words this is about 10 times faster than loadtxt.

along with these two variants, there is also jade.renderFile which generates html that need not be passed to the client.

usage-

var jade = require('jade');

exports.getJson = getJson;

function getJson(req, res) {
    var html = jade.renderFile('views/test.jade', {some:'json'});
    res.send({message: 'i sent json'});
}

getJson() is available as a route in app.js.

You should try this :

pip install tkinter

I hope this would solve the issue.

A cleaner alternative of putting your config file into a subfolder of src/main/resources would be to enhance your classpath locations. This is extremely easy to do with Maven.

For instance, place your property file in a new folder src/main/config, and add the following to your pom:

 <build>
    <resources>
        <resource>
            <directory>src/main/config</directory>
        </resource>
    </resources>
 </build>

From now, every files files under src/main/config is considered as part of your classpath (note that you can exclude some of them from the final jar if needed: just add in the build section:

    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <configuration>
                <excludes>
                    <exclude>my-config.properties</exclude>
                </excludes>
            </configuration>
        </plugin>
    </plugins>

so that my-config.properties can be found in your classpath when you run your app from your IDE, but will remain external from your jar in your final distribution).

Redirection of program output is performed by the shell.

grep ... > output.txt

grep has no mechanism for adding blank lines between each match, but does provide options such as context around the matched line and colorization of the match itself. See the grep(1) man page for details, specifically the -C and --color options.

Use \Q to autoescape any potentially problematic characters in your variable.

if($text_to_search =~ m/\Q$search_string/) print "wee";

You might need to set GEM_HOME for the cleanup to work. You can check what paths exist for gemfiles by running:

gem env

Take note of the GEM PATHS section.

In my case, for example, with gems installed in my user home:

export GEM_HOME="~/.gem/ruby/2.4.0"
gem cleanup

The easiest way I thought of was to just project the point onto the axis of the rectangle. Let me explain:

If you can get the vector from the center of the rectangle to the top or bottom edge and the left or right edge. And you also have a vector from the center of the rectangle to your point, you can project that point onto your width and height vectors.

P = point vector, H = height vector, W = width vector

Get Unit vector W', H' by dividing the vectors by their magnitude

proj_P,H = P - (P.H')H' proj_P,W = P - (P.W')W'

Unless im mistaken, which I don't think I am... (Correct me if I'm wrong) but if the magnitude of the projection of your point on the height vector is less then the magnitude of the height vector (which is half of the height of the rectangle) and the magnitude of the projection of your point on the width vector is, then you have a point inside of your rectangle.

If you have a universal coordinate system, you might have to figure out the height/width/point vectors using vector subtraction. Vector projections are amazing! remember that.

One other difference:

• "adb shell input" is calling the input.jar to process and send the keycode from the Java layer of the android framework.
• "adb sendevent" is actually c code (part of toolbox utility ) that sends the input code directly into the /dev/input.... of Linux input subsystem.

Edit: Sometimes you want to use webpack simply as a module bundler for a simple web project - to keep your own code organized. The following solution is for those who just want an external library to work as expected inside their modules - without using a lot of time diving into webpack setups. (Edited after -1)

Quick and simple (es6) solution if you’re still struggling or want to avoid externals config / additional webpack plugin config:

<script src="cdn/jquery.js"></script>
<script src="cdn/underscore.js"></script>
<script src="etc.js"></script>
<script src="bundle.js"></script>

inside a module:

const { jQuery: $, Underscore: _, etc } = window;

INSERT
INTO    remotedblink.remotedatabase.remoteschema.remotetable
SELECT  *
FROM    mytable

There is no such thing as "the end of the table" in relational databases.

Tried list[:][0] to show all first member of each list inside list is not working. Result is unknowingly will same as list[0][:]

So i use list comprehension like this:

[i[0] for i in list] which return first element value for each list inside list.

I'm assuming the contents of src/main/resources/ is copied to WEB-INF/classes/ inside your .war at build time. If that is the case you can just do (substituting real values for the classname and the path being loaded).

URL sqlScriptUrl = MyServletContextListener.class
                       .getClassLoader().getResource("sql/script.sql");

Yea, Indeed @Evert answer is perfectly correct. In addition I'll like to add one more reason that could encounter such error.

>>> np.array([np.zeros((20,200)),np.zeros((20,200)),np.zeros((20,200))])

This will be perfectly fine, However, This leads to error:

>>> np.array([np.zeros((20,200)),np.zeros((20,200)),np.zeros((20,201))])

ValueError: could not broadcast input array from shape (20,200) into shape (20)

The numpy arry within the list, must also be the same size.

Yes basically this is what virtualenv do , and this is what the activate command is for, from the doc here:

activate script

In a newly created virtualenv there will be a bin/activate shell script, or a Scripts/activate.bat batch file on Windows.

This will change your $PATH to point to the virtualenv bin/ directory. Unlike workingenv, this is all it does; it's a convenience. But if you use the complete path like /path/to/env/bin/python script.py you do not need to activate the environment first. You have to use source because it changes the environment in-place. After activating an environment you can use the function deactivate to undo the changes.

The activate script will also modify your shell prompt to indicate which environment is currently active.

so you should just use activate command which will do all that for you:

> \path\to\env\bin\activate.bat

Specify the type of the pointer to your comparison function as the 3rd type into the map, and provide the function pointer to the map constructor:
map<keyType, valueType, typeOfPointerToFunction> mapName(pointerToComparisonFunction);

Take a look at the example below for providing a comparison function to a map, with vector iterator as key and int as value.

#include "headers.h"

bool int_vector_iter_comp(const vector<int>::iterator iter1, const vector<int>::iterator iter2) {
    return *iter1 < *iter2;
}

int main() {
    // Without providing custom comparison function
    map<vector<int>::iterator, int> default_comparison;

    // Providing custom comparison function
    // Basic version
    map<vector<int>::iterator, int,
        bool (*)(const vector<int>::iterator iter1, const vector<int>::iterator iter2)>
        basic(int_vector_iter_comp);

    // use decltype
    map<vector<int>::iterator, int, decltype(int_vector_iter_comp)*> with_decltype(&int_vector_iter_comp);

    // Use type alias or using
    typedef bool my_predicate(const vector<int>::iterator iter1, const vector<int>::iterator iter2);
    map<vector<int>::iterator, int, my_predicate*> with_typedef(&int_vector_iter_comp);

    using my_predicate_pointer_type = bool (*)(const vector<int>::iterator iter1, const vector<int>::iterator iter2);
    map<vector<int>::iterator, int, my_predicate_pointer_type> with_using(&int_vector_iter_comp);


    // Testing 
    vector<int> v = {1, 2, 3};

    default_comparison.insert(pair<vector<int>::iterator, int>({v.end(), 0}));
    default_comparison.insert(pair<vector<int>::iterator, int>({v.begin(), 0}));
    default_comparison.insert(pair<vector<int>::iterator, int>({v.begin(), 1}));
    default_comparison.insert(pair<vector<int>::iterator, int>({v.begin() + 1, 1}));

    cout << "size: " << default_comparison.size() << endl;

Currently your application support 100 connections in pool. Here is what conn string will look like if you want to increase it to 200:

public static string srConnectionString = 
                "server=localhost;database=mydb;uid=sa;pwd=mypw;Max Pool Size=200;";

You can investigate how many connections with database your application use, by executing sp_who procedure in your database. In most cases default connection pool size will be enough.

Simply declare your variable to final

If you have FFMPEG installed on your server (http://www.mysql-apache-php.com/ffmpeg-install.htm), it is possible to get the attributes of your video using the command "-vstats" and parsing the result with some regex - as shown in the example below. Then, you need the PHP funtion filesize() to get the size.

$ffmpeg_path = 'ffmpeg'; //or: /usr/bin/ffmpeg , or /usr/local/bin/ffmpeg - depends on your installation (type which ffmpeg into a console to find the install path)
$vid = 'PATH/TO/VIDEO'; //Replace here!

 if (file_exists($vid)) {

    $finfo = finfo_open(FILEINFO_MIME_TYPE);
    $mime_type = finfo_file($finfo, $vid); // check mime type
    finfo_close($finfo);

    if (preg_match('/video\/*/', $mime_type)) {

        $video_attributes = _get_video_attributes($vid, $ffmpeg_path);

        print_r('Codec: ' . $video_attributes['codec'] . '<br/>');

        print_r('Dimension: ' . $video_attributes['width'] . ' x ' . $video_attributes['height'] . ' <br/>');

        print_r('Duration: ' . $video_attributes['hours'] . ':' . $video_attributes['mins'] . ':'
                . $video_attributes['secs'] . '.' . $video_attributes['ms'] . '<br/>');

        print_r('Size:  ' . _human_filesize(filesize($vid)));

    } else {
        print_r('File is not a video.');
    }
} else {
    print_r('File does not exist.');
}

function _get_video_attributes($video, $ffmpeg) {

    $command = $ffmpeg . ' -i ' . $video . ' -vstats 2>&1';
    $output = shell_exec($command);

    $regex_sizes = "/Video: ([^,]*), ([^,]*), ([0-9]{1,4})x([0-9]{1,4})/"; // or : $regex_sizes = "/Video: ([^\r\n]*), ([^,]*), ([0-9]{1,4})x([0-9]{1,4})/"; (code from @1owk3y)
    if (preg_match($regex_sizes, $output, $regs)) {
        $codec = $regs [1] ? $regs [1] : null;
        $width = $regs [3] ? $regs [3] : null;
        $height = $regs [4] ? $regs [4] : null;
    }

    $regex_duration = "/Duration: ([0-9]{1,2}):([0-9]{1,2}):([0-9]{1,2}).([0-9]{1,2})/";
    if (preg_match($regex_duration, $output, $regs)) {
        $hours = $regs [1] ? $regs [1] : null;
        $mins = $regs [2] ? $regs [2] : null;
        $secs = $regs [3] ? $regs [3] : null;
        $ms = $regs [4] ? $regs [4] : null;
    }

    return array('codec' => $codec,
        'width' => $width,
        'height' => $height,
        'hours' => $hours,
        'mins' => $mins,
        'secs' => $secs,
        'ms' => $ms
    );
}

function _human_filesize($bytes, $decimals = 2) {
    $sz = 'BKMGTP';
    $factor = floor((strlen($bytes) - 1) / 3);
    return sprintf("%.{$decimals}f", $bytes / pow(1024, $factor)) . @$sz[$factor];
}

I experienced this issue when calling my web api endpoint and solved it.

In my case it was an issue in the way the client was encoding the body content. I was not specifying the encoding or media type. Specifying them solved it.

Not specifying encoding type, caused 415 error:

var content = new StringContent(postData);
httpClient.PostAsync(uri, content);

Specifying the encoding and media type, success:

var content = new StringContent(postData, Encoding.UTF8, "application/json");
httpClient.PostAsync(uri, content);

I tried svn rm --force /path/to/dir to no avail but ended up just running svn up and it fixed it for me.

The "pre Windows 2000" name i.e. DOMAIN\SomeBody, the Somebody portion is known as sAMAccountName.

So try:

using(DirectoryEntry de = new DirectoryEntry("LDAP://MyDomainController"))
{
   using(DirectorySearcher adSearch = new DirectorySearcher(de))
   {
     adSearch.Filter = "(sAMAccountName=someuser)";
     SearchResult adSearchResult = adSearch.FindOne();
   }
}

[email protected] is the UserPrincipalName, but it isn't a required field.

This expression,

(?<=\s|^)[^.\s]+\.[^.\s]+(?=@)

might also work OK for those specific types of input strings.

Demo

Test

import re

expression = r'(?<=^|\s)[^.\s]+\.[^.\s]+(?=@)'
string = '''
blah blah blah [email protected] blah blah
blah blah blah test.this @gmail.com blah blah
blah blah blah [email protected] blah blah
'''

matches = re.findall(expression, string)

print(matches)

Output

['test.this']

If you wish to simplify/modify/explore the expression, it's been explained on the top right panel of regex101.com. If you'd like, you can also watch in this link, how it would match against some sample inputs.

Half a second is 500,000,000 nanoseconds, so your code should read:

tim.tv_sec  = 0;
tim.tv_nsec = 500000000L;

As things stand, you code is sleeping for 1.0000005s (1s + 500ns).

Here is a very nifty way.

First format the content such that the column to be compared for uniqueness is a fixed width. One way of doing this is to use awk printf with a field/column width specifier ("%15s").

Now the -f and -w options of uniq can be used to skip preceding fields/columns and to specify the comparison width (column(s) width).

Here are three examples.

In the first example...

1) Temporarily make the column of interest a fixed width greater than or equal to the field's max width.

2) Use -f uniq option to skip the prior columns, and use the -w uniq option to limit the width to the tmp_fixed_width.

3) Remove trailing spaces from the column to "restore" it's width (assuming there were no trailing spaces beforehand).

printf "%s" "$str" \
| awk '{ tmp_fixed_width=15; uniq_col=8; w=tmp_fixed_width-length($uniq_col); for (i=0;i<w;i++) { $uniq_col=$uniq_col" "}; printf "%s\n", $0 }' \
| uniq -f 7 -w 15 \
| awk '{ uniq_col=8; gsub(/ */, "", $uniq_col); printf "%s\n", $0 }'

In the second example...

Create a new uniq column 1. Then remove it after the uniq filter has been applied.

printf "%s" "$str" \
| awk '{ uniq_col_1=4; printf "%15s %s\n", uniq_col_1, $0 }' \
| uniq -f 0 -w 15 \
| awk '{ $1=""; gsub(/^ */, "", $0); printf "%s\n", $0 }'

The third example is the same as the second, but for multiple columns.

printf "%s" "$str" \
| awk '{ uniq_col_1=4; uniq_col_2=8; printf "%5s %15s %s\n", uniq_col_1, uniq_col_2, $0 }' \
| uniq -f 0 -w 5 \
| uniq -f 1 -w 15 \
| awk '{ $1=$2=""; gsub(/^ */, "", $0); printf "%s\n", $0 }'

You don't need custom directive here. Just use ng-include src attribute. It's compiled so you can put code inside. See plunker with solution for your issue.

<div ng-repeat="week in [1,2]">
  <div ng-repeat="day in ['monday', 'tuesday']">
    <ng-include src="'content/before-'+ week + '-' + day + '.html'"></ng-include>
  </div>
</div>

Okay, it took me a while to see this, but there's no way this compiles:

return String.(ConfigurationManager.AppSettings[paramName]);

You're not even calling a method on the String type. Just do this:

return ConfigurationManager.AppSettings[paramName];

The AppSettings KeyValuePair already returns a string. If the name doesn't exist, it will return null.

Based on your edit you have not yet added a Reference to the System.Configuration assembly for the project you're working in.

It's an unportable way to remove all data from the input buffer till the next newline. I've seen it used in cases like that:

char c;
char s[32];
puts("Type a char");
c=getchar();
fflush(stdin);
puts("Type a string");
fgets(s,32,stdin);

Without the fflush(), if you type a character, say "a", and the hit enter, the input buffer contains "a\n", the getchar() peeks the "a", but the "\n" remains in the buffer, so the next fgets() will find it and return an empty string without even waiting for user input.

However, note that this use of fflush() is unportable. I've tested right now on a Linux machine, and it does not work, for example.

I also have the same problem, and the solution is I didn't bind the event in my onClick. so when it renders for the first time and the data is more, which ends up calling the state setter again, which triggers React to call your function again and so on.

export default function Component(props) {

function clickEvent (event, variable){
    console.log(variable);
}

return (
    <div>
        <IconButton
            key="close"
            aria-label="Close"
            color="inherit"
            onClick={e => clickEvent(e, 10)} // or you can call like this:onClick={() => clickEvent(10)} 
        >
    </div>
)
}

In MacOS, I followed the below steps to make it work.

For the first time, after installation, get the username of the system.

$ cd ~
$ pwd
/Users/someuser
$ psql -d postgres -U someuser

Now that you have logged into the system, and you can create the DB.

postgres=# create database mydb;
CREATE DATABASE
postgres=# create user myuser with encrypted password 'pass123';
CREATE ROLE
postgres=# grant all privileges on database mydb to myuser;
GRANT

SELECT account_id, open_emp_id
         ^^^^        ^^^^
          1           2

FROM account
GROUP BY 1;

In above query GROUP BY 1 refers to the first column in select statement which is account_id.

You also can specify in ORDER BY.

Note : The number in ORDER BY and GROUP BY always start with 1 not with 0.

I was facing the same issue, so I replaced the ".git" folder with a backed up version and it still wasn't working because .gitconfig file was corrupted. The BSOD on my laptop corrupted it. I replaced it with the following code and sourcetree restored all my repositories.

[user]
name = *your username*
email = *your email address*
[core]
autocrlf = true
excludesfile = C:\\Users\\*user name*\\Documents\\gitignore_global.txt

I don't know if this will help anybody, but this is just another solution that worked for me.

You don't want to take care of normalizing your data in a view - what if the user changes the data that gets submitted? Instead you could take care of it in the model using the before_save (or the before_validation) callback. Here's an example of the relevant code for a model like yours:

class Place < ActiveRecord::Base   before_save do |place|     place.city = place.city.downcase.titleize     place.country = place.country.downcase.titleize   end end 

You can also check out the Ruby on Rails guide for more info.

To answer you question more directly, something like this would work:

<%= f.text_field :city, :value => (f.object.city ? f.object.city.titlecase : '') %>   

This just means if f.object.city exists, display the titlecase version of it, and if it doesn't display a blank string.

Workaround that uses overflow-wrap and works fine with normal table layout + table width 100%

https://jsfiddle.net/krf0v6pw/

HTML

<table>
  <tr>
    <td class="overflow-wrap-hack">
      <div class="content">
        wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww
      </div>
    </td>
  </tr>
</table>

CSS

.content{
  word-wrap:break-word; /*old browsers*/
  overflow-wrap:break-word;
}

table{
  width:100%; /*must be set (to any value)*/
}

.overflow-wrap-hack{
  max-width:1px;
}

Benefits:

• Uses overflow-wrap:break-word instead of word-break:break-all. Which is better because it tries to break on spaces first, and cuts the word off only if the word is bigger than it's container.
• No table-layout:fixed needed. Use your regular auto-sizing.
• Not needed to define fixed width or fixed max-width in pixels. Define % of the parent if needed.

I try this. I hope to help. It work with

static void Main()
    {
        string[,] matrix = {
                               { "aa", "aaa" },
                               { "bb", "bbb" }
                           };
        int index = 0;
        foreach (string element in matrix)
        {
            if (index < matrix.GetLength(1))
            {
                Console.Write(element);
                if (index < (matrix.GetLength(1) - 1))
                {
                    Console.Write(" ");
                }
                index++;
            }
            if (index == matrix.GetLength(1))
            {
                Console.Write("\n");
                index = 0;
            }
        }

This worked better for me:

git log --oneline @{upstream}..

or:

git log --oneline origin/(remotebranch)..

You can pause on any XHR pattern which I find very useful during debugging these kind of scenarios.

For example I have given breakpoint on an URL pattern containing "/"

If you include the additional methods file, here's the current file for 1.7: http://ajax.microsoft.com/ajax/jquery.validate/1.7/additional-methods.js

You can use the lettersonly rule :) The additional methods are part of the zip you download, you can always find the latest here.

Here's an example:

$("form").validate({
  rules: {
    myField: { lettersonly: true }
  }
});

It's worth noting, each additional method is independent, you can include that specific one, just place this before your .validate() call:

jQuery.validator.addMethod("lettersonly", function(value, element) {
  return this.optional(element) || /^[a-z]+$/i.test(value);
}, "Letters only please"); 

The answer is very similar to existing ones, but slightly optimized.

So you can find any files or folders by pattern:

def iter_all(pattern, path):
    return (
        os.path.join(root, entry)
        for root, dirs, files in os.walk(path)
        for entry in dirs + files
        if pattern.match(entry)
    )

either by substring:

def iter_all(substring, path):
    return (
        os.path.join(root, entry)
        for root, dirs, files in os.walk(path)
        for entry in dirs + files
        if substring in entry
    )

or using a predicate:

def iter_all(predicate, path):
    return (
        os.path.join(root, entry)
        for root, dirs, files in os.walk(path)
        for entry in dirs + files
        if predicate(entry)
    )

to search only files or only folders - replace “dirs + files”, for example, with only “dirs” or only “files”, depending on what you need.

For MSVC you can use the linker.

link.exe /dump /linenumbers /disasm /out:foo.dis foo.dll

foo.pdb needs to be available to get symbols

While it is possible to combine the results, I would advise against doing so.

You have two fundamentally different types of queries that return a different number of rows, a different number of columns and different types of data. It would be best to leave it as it is - two separate queries.

I've tried SoftReferences, they are too aggressively reclaimed in android that I felt there was no point using them

you need to add jar file in your build path..

commons-dbcp-1.1-RC2.jar

or any version of that..!!!!

ADDED : also make sure you have commons-pool-1.1.jar too in your build path.

ADDED: sorry saw complete list of jar late... may be version clashes might be there.. better check out..!!! just an assumption.

On newer versions of Windows (Windows 10 and Windows Server 2016) the tasks you create are located in C:\Windows\Tasks. They will have the extension .job

For example if you create the task "DoWork" it will create the task in

I´m frequently running into this issue on some custom properties that could not be found using IntelliJ IDEA - likely after changing branches.

What helpes in my case is

File -> Invalidate Caches / Restart

I had the assumption that it is more likely a Gradle caching issue than an IDE issue, but ./gradle clean did not help

Open application manifest (AndroidManifest.xml) and click on Merged Manifest tab on bottom of your edit pane. Check the image below:

From image you can see Error in the right column, try to solve the error. It may help some one with the same problem. Read more here.

Also, once you found the error and if you get that error from external library that you are using, You have to let compiler to ignore the attribute from the external library. //add this attribute in application tag in the manifest

   tools:replace="android:allowBackup"

Try the following simple one-liners:

For all UNIX/OSX/Linux

dir=$(cd -P -- "$(dirname -- "$0")" && pwd -P)

Bash

dir=$(cd -P -- "$(dirname -- "${BASH_SOURCE[0]}")" && pwd -P)

^{Note: A double dash (--) is used in commands to signify the end of command options, so files containing dashes or other special characters won't break the command.}

^{Note: In Bash, use ${BASH_SOURCE[0]} in favor of $0, otherwise the path can break when sourcing it (source/.).}

For Linux, Mac and other *BSD:

cd "$(dirname "$(realpath "$0")")";

^{Note: realpath should be installed in the most popular Linux distribution by default (like Ubuntu), but in some it can be missing, so you have to install it.}

^{Note: If you're using Bash, use ${BASH_SOURCE[0]} in favor of $0, otherwise the path can break when sourcing it (source/.).}

Otherwise you could try something like that (it will use the first existing tool):

cd "$(dirname "$(readlink -f "$0" || realpath "$0")")"

For Linux specific:

cd "$(dirname "$(readlink -f "$0")")"

Using GNU readlink on *BSD/Mac:

cd "$(dirname "$(greadlink -f "$0")")"

Note: You need to have coreutils installed (e.g. 1. Install Homebrew, 2. brew install coreutils).

In bash

In bash you can use Parameter Expansions to achieve that, like:

cd "${0%/*}"

but it doesn't work if the script is run from the same directory.

Alternatively you can define the following function in bash:

realpath () {
  [[ $1 = /* ]] && echo "$1" || echo "$PWD/${1#./}"
}

^{This function takes 1 argument. If argument has already absolute path, print it as it is, otherwise print $PWD variable + filename argument (without ./ prefix).}

or here is the version taken from Debian .bashrc file:

function realpath()
{
    f=$@
    if [ -d "$f" ]; then
        base=""
        dir="$f"
    else
        base="/$(basename "$f")"
        dir=$(dirname "$f")
    fi
    dir=$(cd "$dir" && /bin/pwd)
    echo "$dir$base"
}

Regarding semicolon insertion and the var statement, beware forgetting the comma when using var but spanning multiple lines. Somebody found this in my code yesterday:

    var srcRecords = src.records
        srcIds = [];

It ran but the effect was that the srcIds declaration/assignment was global because the local declaration with var on the previous line no longer applied as that statement was considered finished due to automatic semi-colon insertion.

If someone ends up here from google, looking to convert a single figure to a .pdf (that was what I was looking for):

import matplotlib.pyplot as plt

f = plt.figure()
plt.plot(range(10), range(10), "o")
plt.show()

f.savefig("foo.pdf", bbox_inches='tight')

webRTC or websockets? Why not use both.

When building a video/audio/text chat, webRTC is definitely a good choice since it uses peer to peer technology and once the connection is up and running, you do not need to pass the communication via a server (unless using TURN).

When setting up the webRTC communication you have to involve some sort of signaling mechanism. Websockets could be a good choice here, but webRTC is the way to go for the video/audio/text info. Chat rooms is accomplished in the signaling.

But, as you mention, not every browser supports webRTC, so websockets can sometimes be a good fallback for those browsers.

another option is to use an iframe and set the form's target to it.

you may try this (it uses jQuery):

function ajax_form($form, on_complete)
{
    var iframe;

    if (!$form.attr('target'))
    {
        //create a unique iframe for the form
        iframe = $("<iframe></iframe>").attr('name', 'ajax_form_' + Math.floor(Math.random() * 999999)).hide().appendTo($('body'));
        $form.attr('target', iframe.attr('name'));
    }

    if (on_complete)
    {
        iframe = iframe || $('iframe[name="' + $form.attr('target') + '"]');
        iframe.load(function ()
        {
            //get the server response
            var response = iframe.contents().find('body').text();
            on_complete(response);
        });
    }
}

it works well with all browsers, you don't need to serialize or prepare the data. one down side is that you can't monitor the progress.

also, at least for chrome, the request will not appear in the "xhr" tab of the developer tools but under "doc"

A workaround - at least for the minimum size: You can use grid to manage the frames contained in root and make them follow the grid size by setting sticky='nsew'. Then you can use root.grid_rowconfigure and root.grid_columnconfigure to set values for minsize like so:

from tkinter import Frame, Tk

class MyApp():
    def __init__(self):
        self.root = Tk()

        self.my_frame_red = Frame(self.root, bg='red')
        self.my_frame_red.grid(row=0, column=0, sticky='nsew')

        self.my_frame_blue = Frame(self.root, bg='blue')
        self.my_frame_blue.grid(row=0, column=1, sticky='nsew')

        self.root.grid_rowconfigure(0, minsize=200, weight=1)
        self.root.grid_columnconfigure(0, minsize=200, weight=1)
        self.root.grid_columnconfigure(1, weight=1)

        self.root.mainloop()

if __name__ == '__main__':
    app = MyApp()

But as Brian wrote (in 2010 :D) you can still resize the window to be smaller than the frame if you don't limit its minsize.

Just set Null to ignore parameters that you don't want to use and then set the parameter needed according to the position.

 function myFunc($p1,$p2,$p3=Null,$p4=Null,$p5=Null,$p6=Null,$p7=Null,$p8=Null){
    for ($i=1; $i<9; $i++){
        $varName = "p$i";
        if (isset($$varName)){
            echo $varName." = ".$$varName."<br>\n";
        }
    }
}   

myFunc( "1", "2", Null, Null, Null, Null, Null, "eight" );

I'd like to expand on Leor's suggestion for anyone confused on how to compute the nearest location and actually provide a working solution:

I'm using markers in a markers array e.g. var markers = [];.

Then let's have our position as something like var location = new google.maps.LatLng(51.99, -0.74);

Then we simply reduce our markers against the location we have like so:

markers.reduce(function (prev, curr) {

    var cpos = google.maps.geometry.spherical.computeDistanceBetween(location.position, curr.position);
    var ppos = google.maps.geometry.spherical.computeDistanceBetween(location.position, prev.position);

    return cpos < ppos ? curr : prev;

}).position

What pops out is your closest marker LatLng object.

Thread is a class, not an instance; currentThread() is a static method that returns the Thread instance corresponding to the calling thread.

Use (2). interrupt() is a bit brutal for normal use.

I think we should go with StringBuilder append approach. Reason being :

1. The String concatenate will create a new string object each time (As String is immutable object) , so it will create 3 objects.

2. With String builder only one object will created[StringBuilder is mutable] and the further string gets appended to it.

The axes class has a set_yticklabels function which allows you to set the tick labels, like so:

#ax is the axes instance
group_labels = ['control', 'cold treatment',
             'hot treatment', 'another treatment',
             'the last one']

ax.set_xticklabels(group_labels)

I'm still working on why your example above didn't work.

This is an old question, but one that is frequently visited and clear recommendations are now available from RFC 7303 which obsoletes RFC3023. In a nutshell (section 9.2):

The registration information for text/xml is in all respects the same
as that given for application/xml above (Section 9.1), except that
the "Type name" is "text".

You could do many of the given answers, but if you just want to do it to be able to use it with strcpy, then you could do the following:

...
    strcpy( ... , (char[2]) { (char) c, '\0' } );
...

The (char[2]) { (char) c, '\0' } part will temporarily generate null-terminated string out of a character c.

This way you could avoid creating new variables for something that you already have in your hands, provided that you'll only need that single-character string just once.

$users = $dbh->query($sql);
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}

Here $users is a PDOStatement object over which you can iterate. The first iteration outputs all results, the second does nothing since you can only iterate over the result once. That's because the data is being streamed from the database and iterating over the result with foreach is essentially shorthand for:

while ($row = $users->fetch()) ...

Once you've completed that loop, you need to reset the cursor on the database side before you can loop over it again.

$users = $dbh->query($sql);
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}
echo "<br/>";
$result = $users->fetch(PDO::FETCH_ASSOC);
foreach($result as $key => $value) {
    echo $key . "-" . $value . "<br/>";
}

Here all results are being output by the first loop. The call to fetch will return false, since you have already exhausted the result set (see above), so you get an error trying to loop over false.

In the last example you are simply fetching the first result row and are looping over it.

Here's another way to plot the data, involves turning the date_time into an index, this might help you for future slicing

#convert column to datetime
trip_data['lpep_pickup_datetime'] = pd.to_datetime(trip_data['lpep_pickup_datetime'])
#turn the datetime to an index
trip_data.index = trip_data['lpep_pickup_datetime']
#Plot
trip_data['Trip_distance'].plot(kind='hist')
plt.show()

Try:

alter table <your table> modify <column name> null;

Another one:

def local_maxima_mask(vec):
    """
    Get a mask of all points in vec which are local maxima
    :param vec: A real-valued vector
    :return: A boolean mask of the same size where True elements correspond to maxima. 
    """
    mask = np.zeros(vec.shape, dtype=np.bool)
    greater_than_the_last = np.diff(vec)>0  # N-1
    mask[1:] = greater_than_the_last
    mask[:-1] &= ~greater_than_the_last
    return mask

<script>
function check(){
    return false;
}
 </script>

</form>

public String UpperCaseWords(String line)
{
    line = line.trim().toLowerCase();
    String data[] = line.split("\\s");
    line = "";
    for(int i =0;i< data.length;i++)
    {
        if(data[i].length()>1)
            line = line + data[i].substring(0,1).toUpperCase()+data[i].substring(1)+" ";
        else
            line = line + data[i].toUpperCase();
    }
    return line.trim();
}

std::move itself does nothing rather than a static_cast. According to cppreference.com

It is exactly equivalent to a static_cast to an rvalue reference type.

Thus, it depends on the type of the variable you assign to after the move, if the type has constructors or assign operators that takes a rvalue parameter, it may or may not steal the content of the original variable, so, it may leave the original variable to be in an unspecified state:

Unless otherwise specified, all standard library objects that have been moved from being placed in a valid but unspecified state.

Because there is no special move constructor or move assign operator for built-in literal types such as integers and raw pointers, so, it will be just a simple copy for these types.

If every char in the file is properly encoded in UTF-8, you won't have any problem reading it using a reader with the UTF-8 encoding. Up to you to check every char of the file and see if you consider it printable or not.

ReactJS: Maximum update depth exceeded error

inputDigit(digit){
  this.setState({
    displayValue: String(digit)
  })

<button type="button"onClick={this.inputDigit(0)}>

why that?

<button type="button"onClick={() => this.inputDigit(1)}>1</button>

The function onDigit sets the state, which causes a rerender, which causes onDigit to fire because that’s the value you’re setting as onClick which causes the state to be set which causes a rerender, which causes onDigit to fire because that’s the value you’re… Etc

3 answers, which you can combine:

1. Set implicit wait immediately after creating the web driver instance:

   _ = driver.Manage().Timeouts().ImplicitWait;

   This will try to wait until the page is fully loaded on every page navigation or page reload.

2. After page navigation, call JavaScript return document.readyState until "complete" is returned. The web driver instance can serve as JavaScript executor. Sample code:

   C#

   new WebDriverWait(driver, MyDefaultTimeout).Until(
   d => ((IJavaScriptExecutor) d).ExecuteScript("return document.readyState").Equals("complete"));
   

   Java

   new WebDriverWait(firefoxDriver, pageLoadTimeout).until(
         webDriver -> ((JavascriptExecutor) webDriver).executeScript("return document.readyState").equals("complete"));
   

3. Check if the URL matches the pattern you expect.

It is also used for debugging purposes.

Here is a handy list of some of these values:

http://en.wikipedia.org/wiki/Magic_number_%28programming%29#Magic_debug_values

You need to indicate JAVA_HOME in mvn.ini (it's in the Maven folder /bin), and your problem will disappear.

Most answers get you the current path and are context sensitive. In order to run your script from any directory, use the below snippet.

DIR="$( cd "$( dirname "$0" )" && pwd )"

By switching directories in a subshell, we can then call pwd and get the correct path of the script regardless of context.

You can then use $DIR as "$DIR/path/to/file"

If you want to treat accented latin characters (eg. à Ñ) as normal letters (ie. avoid matching them too), you'll also need to include the appropriate Unicode range (\u00C0-\u00FF) in your regex, so it would look like this:

/[^a-zA-Z\d\s:\u00C0-\u00FF]/g

• ^ negates what follows
• a-zA-Z matches upper and lower case letters
• \d matches digits
• \s matches white space (if you only want to match spaces, replace this with a space)
• : matches a colon
• \u00C0-\u00FF matches the Unicode range for accented latin characters.

nb. Unicode range matching might not work for all regex engines, but the above certainly works in Javascript (as seen in this pen on Codepen).

nb2. If you're not bothered about matching underscores, you could replace a-zA-Z\d with \w, which matches letters, digits, and underscores.

Add json jar to your classpath

or use java -classpath json.jar ClassName

I had a similar problem. My data is provided by a remote server. I want some value to be entered in the selectize box, but it is not sure in advance whether this value is a valid one on the server.

So I want the value to be entered in the box, and I want selectize to show the possible options just if like the user had entered the value.

I ended up using this hack (which it is probably unsupported):

var $selectize = $("#my_input").selectize(/* settings with load*/);
var selectize = $select[0].selectize;
// get the search from the remote server
selectize.onSearchChange('my value');
// enter the input in the input field
$selectize.parent().find('input').val('my value');
// focus on the input field, to make the options visible
$selectize.parent().find('input').focus();

Here is a simple couple lines that looks for extention as well as provides a sort option

def get_sorted_files(src_dir, regex_ext='*', sort_reverse=False): 
    files_to_evaluate = [os.path.join(src_dir, f) for f in os.listdir(src_dir) if re.search(r'.*\.({})$'.format(regex_ext), f)]
    files_to_evaluate.sort(key=os.path.getmtime, reverse=sort_reverse)
    return files_to_evaluate

Be careful that this will create an "alternate reality" for people who have already fetch/pulled/cloned from the remote repository. But in fact, it's quite simple:

git reset HEAD^ # remove commit locally
git push origin +HEAD # force-push the new HEAD commit

If you want to still have it in your local repository and only remove it from the remote, then you can use:

git push origin +HEAD^:<name of your branch, most likely 'master'>

Based in this implementation with Node.js of JWT with refresh token:

1) In this case they use a uid and it's not a JWT. When they refresh the token they send the refresh token and the user. If you implement it as a JWT, you don't need to send the user, because it would inside the JWT.

2) They implement this in a separated document (table). It has sense to me because a user can be logged in in different client applications and it could have a refresh token by app. If the user lose a device with one app installed, the refresh token of that device could be invalidated without affecting the other logged in devices.

3) In this implementation it response to the log in method with both, access token and refresh token. It seams correct to me.

You may need read this https://developer.android.com/guide/topics/resources/drawable-resource.html#Shape

and below there is a Note.

Note Every corner must (initially) be provided a corner radius greater than 1, or else no corners are rounded. If you want specific corners to not be rounded, a work-around is to use android:radius to set a default corner radius greater than 1, but then override each and every corner with the values you really want, providing zero ("0dp") where you don't want rounded corners.

If Character.isLetter(ch) looks a bit wordy/ugly you can use a static import.

import static java.lang.Character.*;


if(isLetter(ch)) {

} else if(isDigit(ch)) {

} 

What I use:

set long 50000
set linesize 130

Or am I missing something?

As others have said, you can use the dependency:analyze goal to find which dependencies are used and declared, used and undeclared, or unused and declared. You may also find dependency:analyze-dep-mgt useful to look for mismatches in your dependencyManagement section.

You can simply remove unwanted direct dependencies from your POM, but if they are introduced by third-party jars, you can use the <exclusions> tags in a dependency to exclude the third-party jars (see the section titled Dependency Exclusions for details and some discussion). Here is an example excluding commons-logging from the Spring dependency:

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring</artifactId>
  <version>2.5.5</version>
  <exclusions>
    <exclusion>
      <groupId>commons-logging</groupId>
      <artifactId>commons-logging</artifactId>
    </exclusion>
  </exclusions> 
</dependency>

The main problem with your example code is that the $result variable you use to store the output of curl_exec() does not contain the body of the HTTP response - it contains the value true. If you try to print_r() that, it will just say "1".

The curl_exec() reference explains:

Return Values

Returns TRUE on success or FALSE on failure. However, if the CURLOPT_RETURNTRANSFER option is set, it will return the result on success, FALSE on failure.

So if you want to get the HTTP response body in your $result variable, you must first run

curl_setopt($cURL, CURLOPT_RETURNTRANSFER, true);

After that, you can call json_decode() on $result, as other answers have noted.

On a general note - the curl library for PHP is useful and has a lot of features to handle the minutia of HTTP protocol (and others), but if all you want is to GET some resource or even POST to some URL, and read the response - then file_get_contents() is all you'll ever need: it is much simpler to use and have much less surprising behavior to worry about.

if you using vscode,make sure your package directory is out of the _pychache__ directory.

Try this:

$("#location").change(function(){
            var element = $("option:selected", this);
            var myTag = element.attr("myTag");

            $('#setMyTag').val(myTag);
        });

In the callback function for change(), this refers to the select, not to the selected option.

nodeEnter.append("svg:image")
.attr('x', -9)
.attr('y', -12)
.attr('width', 20)
.attr('height', 24)
.attr("xlink:href", "resources/images/check.png")

You could use the n-th child selector.

to target the nth element you could then use:

td:nth-child(n) {  
  /* your stuff here */
}

(where n starts at 1)

Enter the formula =ROW() into any cell and that cell will show the row number as its value.

If you want 1001, 1002 etc just enter =1000+ROW()

This actually works for me:

background-color: #6DB3F2;
background-image: url('images/checked.png');

You can also drop a solid shadow and set the background image:

background-image: url('images/checked.png');
box-shadow: inset 0 0 100% #6DB3F2;

If the first option is not working for some reason and you don't want to use the box shadow you can always use a pseudo element for the image without any extra HTML:

.btn{
    position: relative;
    background-color: #6DB3F2;
}
.btn:before{
    content: "";
    display: block;
    width: 100%;
    height: 100%;
    position:absolute;
    top:0;
    left:0;
    background-image: url('images/checked.png');
}

I had the same issue for a while and had a very hard time figuring it out. My problem was that I had the site working for a while with the sessions working right, and then all of the sudden everything broke.

Apparently, your session_save_path(), for me it was /var/lib/php5/, needs to have correct permissions (the user running php, eg www-data needs write access to the directory). I accidentally changed it, breaking sessions completely.

Run sudo chmod -R 700 /var/lib/php5/ and then sudo chown -R www-data /var/lib/php5/ so that the php user has access to the folder.
