For the first question I think answer would be:

<your DataFrame>.rename(columns={'count':'Total_Numbers'})

or

<your DataFrame>.columns = ['ID', 'Region', 'Total_Numbers']

As for second one I'd say the answer would be no. It's possible to use it like 'df.ID' because of python datamodel:

Attribute references are translated to lookups in this dictionary, e.g., m.x is equivalent to m.dict["x"]

The precompiled binaries on http://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python is just worked for me.

1. Open MySQL_python-1.2.5-cp27-none-win_amd64.whl file with zip extractor program.
2. Copy the contents to C:\Python27\Lib\site-packages\

Ruby is interpreted. Variables are references to data, but not the data itself. This facilitates using the same variable for data of different types.

Assignment of lhs = rhs then copies the reference on the rhs, not the data. This differs in other languages, such as C, where assignment does a data copy to lhs from rhs.

So for the function call, the variable passed, say x, is indeed copied into a local variable in the function, but x is a reference. There will then be two copies of the reference, both referencing the same data. One will be in the caller, one in the function.

Assignment in the function would then copy a new reference to the function's version of x. After this the caller's version of x remains unchanged. It is still a reference to the original data.

In contrast, using the .replace method on x will cause ruby to do a data copy. If replace is used before any new assignments then indeed the caller will see the data change in its version also.

Similarly, as long as the original reference is in tact for the passed in variable, the instance variables will be the same that the caller sees. Within the framework of an object, the instance variables always have the most up to date reference values, whether those are provided by the caller or set in the function the class was passed in to.

The 'call by value' or 'call by reference' is muddled here because of confusion over '=' In compiled languages '=' is a data copy. Here in this interpreted language '=' is a reference copy. In the example you have the reference passed in followed by a reference copy though '=' that clobbers the original passed in reference, and then people talking about it as though '=' were a data copy.

To be consistent with definitions we must keep with '.replace' as it is a data copy. From the perspective of '.replace' we see that this is indeed pass by reference. Furthermore, if we walk through in the debugger, we see references being passed in, as variables are references.

However if we must keep '=' as a frame of reference, then indeed we do get to see the passed in data up until an assignment, and then we don't get to see it anymore after assignment while the caller's data remains unchanged. At a behavioral level this is pass by value as long as we don't consider the passed in value to be composite - as we won't be able to keep part of it while changing the other part in a single assignment (as that assignment changes the reference and the original goes out of scope). There will also be a wart, in that instance variables in objects will be references, as are all variables. Hence we will be forced to talk about passing 'references by value' and have to use related locutions.

What do you mean by impacts? Content will flow around a float. That's how they work.

If you want it to appear above your design, try setting:

z-index: 10;  
position: absolute;  
right: 0;  
top: 0;

original answer by @yurzui won't work startring from Angular 9 due to - strange problem migrating angular 8 app to 9. However, you can still benefit from ngVar directive by having it and using it like

<ng-template [ngVar]="variable">
your code
</ng-template>

although it could result in IDE warning: "variable is not defined"

function millisecondsToTime(millisecs){
  var ms = Math.abs(millisecs) % 1000;
  var secs = (millisecs < 0 ? -1 : 1) * ((Math.abs(millisecs) - ms) / 1000);
  ms = '' + ms;
  ms = '000'.substring(ms.length) + ms;
  return secsToTime(secs) + '.' + ms;
}

There is no difference between moving and renaming; you should simply call Directory.Move.

In general, if you're only doing a single operation, you should use the static methods in the File and Directory classes instead of creating FileInfo and DirectoryInfo objects.

For more advice when working with files and directories, see here.

You do not exactly define what the dictionaries should look like, but most likely you are referring to QuerySet.values(). From the official django documentation:

Returns a ValuesQuerySet — a QuerySet subclass that returns dictionaries when used as an iterable, rather than model-instance objects.

Each of those dictionaries represents an object, with the keys corresponding to the attribute names of model objects.

You're looking for a non-greedy (or lazy) match. To get a non-greedy match in regular expressions you need to use the modifier ? after the quantifier. For example you can change .* to .*?.

By default grep doesn't support non-greedy modifiers, but you can use grep -P to use the Perl syntax.

In development
In your app folder create folder name 'static' and save your picture in that folder.
To use picture use:

<html>
    <head>
       {% load staticfiles %} <!-- Prepare django to load static files -->
    </head>
    <body>
        <img src={% static "image.jpg" %}>
    </body>
</html>

In production:
Everything same like in development, just add couple more parameters for Django:

1. add in settings.py
   STATIC_ROOT = os.path.join(BASE_DIR, "static/")(this will prepare folder where static files from all apps will be stored)

2. be sure your app is in INSTALLED_APPS = ['myapp',]

3. in terminall run command python manage.py collectstatic (this will make copy of static files from all apps included in INSTALLED_APPS to global static folder - STATIC_ROOT folder )
   
   Thats all what Django need, after this you need to make some web server side setup to make premissions for use static folder. E.g. in apache2 in configuration file httpd.conf (for windows) or sites-enabled/000-default.conf. (under site virtual host part for linux) add:

   Alias \static "path_to_your_project\static"

   Require all granted
   
   And that's all

I have the same wonder today, I did on this way :

//<img src="actual.png" alt="myImage" class=myClass>
$('.myClass').attr('src','').promise().done(function() {
$(this).attr('src','img/new.png');  
});

Try this --

fseek(fp, 0, SEEK_END);
unsigned long int file_size = ftell(fp);
rewind(fp);

What this does is first, seek to the end of the file; then, report where the file pointer is. Lastly (this is optional) it rewinds back to the beginning of the file. Note that fp should be a binary stream.

file_size contains the number of bytes the file contains. Note that since (according to climits.h) the unsigned long type is limited to 4294967295 bytes (4 gigabytes) you'll need to find a different variable type if you're likely to deal with files larger than that.

In my case (OS X) it was because I have set GOPATH to /home/username/go (as per the book) instead of /Users/username/go

There is the option to use OleDB and use the Excel sheets like datatables in a database...

Just an example.....

string con =
  @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\temp\test.xls;" + 
  @"Extended Properties='Excel 8.0;HDR=Yes;'";    
using(OleDbConnection connection = new OleDbConnection(con))
{
    connection.Open();
    OleDbCommand command = new OleDbCommand("select * from [Sheet1$]", connection); 
    using(OleDbDataReader dr = command.ExecuteReader())
    {
         while(dr.Read())
         {
             var row1Col0 = dr[0];
             Console.WriteLine(row1Col0);
         }
    }
}

This example use the Microsoft.Jet.OleDb.4.0 provider to open and read the Excel file. However, if the file is of type xlsx (from Excel 2007 and later), then you need to download the Microsoft Access Database Engine components and install it on the target machine.

The provider is called Microsoft.ACE.OLEDB.12.0;. Pay attention to the fact that there are two versions of this component, one for 32bit and one for 64bit. Choose the appropriate one for the bitness of your application and what Office version is installed (if any). There are a lot of quirks to have that driver correctly working for your application. See this question for example.

Of course you don't need Office installed on the target machine.

While this approach has some merits, I think you should pay particular attention to the link signaled by a comment in your question Reading excel files from C#. There are some problems regarding the correct interpretation of the data types and when the length of data, present in a single excel cell, is longer than 255 characters

If you are already using the networkx library, then you can implement a tree using that. Otherwise, you can try one of the other answers.

NetworkX is a Python package for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks.

As 'tree' is another term for a (normally rooted) connected acyclic graph, and these are called 'arborescences' in NetworkX.

You may want to implement a plane tree (aka ordered tree) where each sibling has a unique rank and this is normally done via labelling the nodes.

However, graph language looks different from tree language, and the means of 'rooting' an arborescence is normally done by using a directed graph so, while there are some really cool functions and corresponding visualisations available, it would probably not be an ideal choice if you are not already using networkx.

An example of building a tree:

import networkx as nx
G = nx.Graph()
G.add_edge('A', 'B')
G.add_edge('B', 'C')
G.add_edge('B', 'D')
G.add_edge('A', 'E')
G.add_edge('E', 'F')

The library enables each node to be any hashable object, and there is no constraint on the number of children each node has.

The library also provides graph algorithms related to trees and visualization capabilities.

db.delete(TABLE_NAME, null, null);

or, if you want the function to return the count of deleted rows,

db.delete(TABLE_NAME, "1", null);

From the documentation of SQLiteDatabase delete method:

To remove all rows and get a count pass "1" as the whereClause.

Please read and strongly consider my advice in the comments of your post. That being said, if you still have a good reason to do this, check out this list of crypto modules for Node. It has modules for dealing with both sha1 and base64.

Copy & paste example for upserting one table into another, with MERGE:

CREATE GLOBAL TEMPORARY TABLE t1
    (id VARCHAR2(5) ,
     value VARCHAR2(5),
     value2 VARCHAR2(5)
     )
  ON COMMIT DELETE ROWS;

CREATE GLOBAL TEMPORARY TABLE t2
    (id VARCHAR2(5) ,
     value VARCHAR2(5),
     value2 VARCHAR2(5))
  ON COMMIT DELETE ROWS;
ALTER TABLE t2 ADD CONSTRAINT PK_LKP_MIGRATION_INFO PRIMARY KEY (id);

insert into t1 values ('a','1','1');
insert into t1 values ('b','4','5');
insert into t2 values ('b','2','2');
insert into t2 values ('c','3','3');


merge into t2
using t1
on (t1.id = t2.id) 
when matched then 
  update set t2.value = t1.value,
  t2.value2 = t1.value2
when not matched then
  insert (t2.id, t2.value, t2.value2)  
  values(t1.id, t1.value, t1.value2);

select * from t2

Result:

1. b 4 5
2. c 3 3
3. a 1 1

Like this... I used it to read Chinese characters...

Dim reader as StreamReader = My.Computer.FileSystem.OpenTextFileReader(filetoimport.Text)
Dim a as String

Do
   a = reader.ReadLine
   '
   ' Code here
   '
Loop Until a Is Nothing

reader.Close()

You need to set JDK 1.5 to your project and also all dependent project or jar file should also compiled with JDK 1.5

Try using the WebConfigurationManager class instead. For example:

string userName = WebConfigurationManager.AppSettings["PFUserName"]

I've used a few CSS hacks and targeted Chrome/Safari/Firefox/IE individually, as each browser renders selects a bit differently. I've tested on all browsers except IE.

For Safari/Chrome, set the height and line-height you want for your <select />.

For Firefox, we're going to kill Firefox's default padding and border, then set our own. Set padding to whatever you like.

For IE 8+, just like Chrome, we've set the height and line-height properties. These two media queries can be combined. But I kept it separate for demo purposes. So you can see what I'm doing.

Please note, for the height/line-height property to work in Chrome/Safari OSX, you must set the background to a custom value. I changed the color in my example.

Here's a jsFiddle of the below: http://jsfiddle.net/URgCB/4/

For the non-hack route, why not use a custom select plug-in via jQuery? Check out this: http://codepen.io/wallaceerick/pen/ctsCz

HTML:

<select>
    <option>Here's one option</option>
    <option>here's another option</option>
</select>

CSS:

@media screen and (-webkit-min-device-pixel-ratio:0) {  /*safari and chrome*/
    select {
        height:30px;
        line-height:30px;
        background:#f4f4f4;
    } 
}
select::-moz-focus-inner { /*Remove button padding in FF*/ 
    border: 0;
    padding: 0;
}
@-moz-document url-prefix() { /* targets Firefox only */
    select {
        padding: 15px 0!important;
    }
}        
@media screen\0 { /* IE Hacks: targets IE 8, 9 and 10 */        
    select {
        height:30px;
        line-height:30px;
    }     
}

Here's what worked for me, here I'm attaching a file to my EmailController under test. Also take a look at the postman screenshot on how I'm posting the data.

                        MediaType.MULTIPART_FORM_DATA_VALUE,
                        fileResource.getInputStream());  
                        assertNotNull(firstFile);


            MockMvc mockMvc = MockMvcBuilders.

I was making my own version of a Checkbox to control a DataGridViewCheckBoxColumn when I saw this post wasn't actually answered. To set the checked state of a DataGridViewCheckBoxCell use:

foreach (DataGridViewRow row in dataGridView1.Rows)
{
    dataGridView1.Rows[row.Index].SetValues(true);
}

For anyone else trying to accomplish the same thing, here is what I came up with.

This makes the two controls behave like the checkbox column in Gmail. It keeps functionality for both mouse and keyboard.

using System;
using System.Windows.Forms;

namespace Check_UnCheck_All
{
    public partial class Check_UnCheck_All : Form
    {
        public Check_UnCheck_All()
        {
            InitializeComponent();
            dataGridView1.RowCount = 10;
            dataGridView1.AllowUserToAddRows = false;
            this.dataGridView1.CellContentClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.dgvApps_CellContentClick);
            this.dataGridView1.CellMouseUp += new System.Windows.Forms.DataGridViewCellMouseEventHandler(this.myDataGrid_OnCellMouseUp);
            this.dataGridView1.CellValueChanged += new System.Windows.Forms.DataGridViewCellEventHandler(this.myDataGrid_OnCellValueChanged);
            this.checkBox1.Click += new System.EventHandler(this.checkBox1_Click);
        }

        public int chkInt = 0;
        public bool chked = false;

        public void myDataGrid_OnCellValueChanged(object sender, DataGridViewCellEventArgs e)
        {
            if (e.ColumnIndex == dataGridView1.Rows[0].Index && e.RowIndex != -1)
            {
                DataGridViewCheckBoxCell chk = dataGridView1.Rows[e.RowIndex].Cells[0] as DataGridViewCheckBoxCell;

                if (Convert.ToBoolean(chk.Value) == true) chkInt++;
                if (Convert.ToBoolean(chk.Value) == false) chkInt--;
                if (chkInt < dataGridView1.Rows.Count && chkInt > 0)
                {
                    checkBox1.CheckState = CheckState.Indeterminate;
                    chked = true;
                }
                else if (chkInt == 0)
                {
                    checkBox1.CheckState = CheckState.Unchecked;
                    chked = false;
                }
                else if (chkInt == dataGridView1.Rows.Count)
                {
                    checkBox1.CheckState = CheckState.Checked;
                    chked = true;
                }
            }
        }
        public void myDataGrid_OnCellMouseUp(object sender, DataGridViewCellMouseEventArgs e)
        {
            // End of edition on each click on column of checkbox
            if (e.ColumnIndex == dataGridView1.Rows[0].Index && e.RowIndex != -1)

ADDENDUM: For Windows 8 this will not work; see this excellent answer instead.

Found this solution here: http://www.robvanderwoude.com/clevertricks.php

AT > NUL
IF %ERRORLEVEL% EQU 0 (
    ECHO you are Administrator
) ELSE (
    ECHO you are NOT Administrator. Exiting...
    PING 127.0.0.1 > NUL 2>&1
    EXIT /B 1
)

Assuming that doesn't work and since we're talking Win7 you could use the following in Powershell if that's suitable:

$principal = new-object System.Security.Principal.WindowsPrincipal([System.Security.Principal.WindowsIdentity]::GetCurrent())
$principal.IsInRole([System.Security.Principal.WindowsBuiltInRole]::Administrator)

If not (and probably not, since you explicitly proposed batch files) then you could write the above in .NET and return an exit code from an exe based on the result for your batch file to use.

To complement the previous stated solution, use:

str = str.replace("%", "%%");

//try this to pick image from gallery..
    public void gotogallery(View view) { 
// onclick for gallery button
        chooseImage();
    }
// choose image from gallery
          public void chooseImage() {
        Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST); //activity result method call
    }

    @Override
    protected void onActivityResult(int requestcode,int resultcode,Intent data ) {
        super.onActivityResult(requestcode, resultcode, data);

        if (requestcode == PICK_IMAGE_REQUEST && resultcode == RESULT_OK && data != null && data.getData() != null) {

            Uri uri = data.getData();

            try {
           Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);


                slectimageview=findViewById(R.id.imageviewimagetopdf_id);
                slectimageview.setImageBitmap(bitmap);


            } catch (IOException e) {
                e.printStackTrace();
            }
        }


    }

Here's a method I wrote to check if an URL exists or not. I had a requirement to add a request header. It's Groovy but should be fairly simple to adapt to Java. Essentially I'm using the org.springframework.web.client.RestTemplate#execute(java.lang.String, org.springframework.http.HttpMethod, org.springframework.web.client.RequestCallback, org.springframework.web.client.ResponseExtractor<T>, java.lang.Object...) API method. I guess the solution you arrive at depends at least in part on the HTTP method you want to execute. The key take away from example below is that I'm passing a Groovy closure (The third parameter to method restTemplate.execute(), which is more or less, loosely speaking a Lambda in Java world) that is executed by the Spring API as a callback to be able to manipulate the request object before Spring executes the command,

boolean isUrlExists(String url) {
    try {
      return (restTemplate.execute(url, HttpMethod.HEAD,
              { ClientHttpRequest request -> request.headers.add('header-name', 'header-value') },
              { ClientHttpResponse response -> response.headers }) as HttpHeaders)?.get('some-response-header-name')?.contains('some-response-header-value')
    } catch (Exception e) {
      log.warn("Problem checking if $url exists", e)
    }
    false
  }

You need to give relative or absolute or fixed positioning to your container (#shop) and set its zIndex to say 100.

You also need to give say relative positioning to your elements with the class content and lower zIndex say 97.

Do the above-mentioned with your images too and set their zIndex to 91.

And then position your button higher by setting its position to absolute and zIndex to 95

Did you try:

$DBH = new PDO( "connection string goes here" );
$row = $DBH->query( "select figure from table1" )->fetch();
echo $row["figure"];
$DBH = null;

The other answers are lacking on the reordering descriptions.

git push <remotename> <commit SHA>:<remotebranchname>

will push a single commit, but that commit has to be the OLDEST of your local, non-pushed, commits, not to be confused with the top, first, or tip commit, which are all ambiguous descriptions in my opinion. The commit needs to the oldest of your commits, i.e. the furthest from your most recent commit. If it's not the oldest commit then all commits from your oldest, local, non-pushed SHA to the SHA specified will be pushed. To reorder the commits use:

git rebase -i HEAD~xxx

After reordering the commit you can safely push it to the remote repository.

To summarize, I used

git rebase -i HEAD~<number of commits to SHA>
git push origin <post-rebase SHA>:master

to push a single commit to my remote master branch.

You can use colMeans:

### Sample data
set.seed(1)
m <- data.frame(matrix(sample(100, 20, replace = TRUE), ncol = 4))

### Your error
mean(m)
# [1] NA
# Warning message:
# In mean.default(m) : argument is not numeric or logical: returning NA

### The result using `colMeans`
colMeans(m)
#   X1   X2   X3   X4 
# 47.0 64.4 44.8 67.8

Sometimes there are error while installing the node modules Try this:

1. Delete node_modules
2. npm install

You can instantiate a color with three floats (r, g, b), each between 0.0 and 1.0: http://download.oracle.com/javase/6/docs/api/java/awt/Color.html#Color(float,%20float,%20float).

Using Java's Random class you can easily instantiate a new random color as such:

Random r = new Random();
Color randomColor = new Color(r.nextFloat(), r.nextFloat(), r.nextFloat());

I can't guarantee they'll all be pretty, but they'll be random =)

Even I have faced the same question in multiple interviews and believe me it makes your time miserable to convince the interviewer. If I inherent all the answers from above then I need to add one more key point to make it more convincing and utilizing OO at its best

In case you are not planning any modification in the rules , for the subclass to be followed, for a long future, go for the interface, as you wont be able to modify in it and if you do so, you need to go for the changes in all the other sub classes, whereas, if you think, you want to reuse the functionality, set some rules and also make it open for modification, go for Abstract class.

Think in this way, you had used a consumable service or you had provided some code to world and You have a chance to modify something, suppose a security check And If I am being a consumer of the code and One morning after a update , I find all read marks in my Eclipse, entire application is down. So to prevent such nightmares, use Abstract over Interfaces

I think this might convince the Interviewer to a extent...Happy Interviews Ahead.

Not to trample on BBoy's already decent answer, but I've done the code that maintains aspect ratio. I took his suggestion, so he should get partial credit here!

PrintDocument pd = new PrintDocument();
pd.DefaultPageSettings.PrinterSettings.PrinterName = "Printer Name";
pd.DefaultPageSettings.Landscape = true; //or false!
pd.PrintPage += (sender, args) =>
{
    Image i = Image.FromFile(@"C:\...\...\image.jpg");
    Rectangle m = args.MarginBounds;

    if ((double)i.Width / (double)i.Height > (double)m.Width / (double)m.Height) // image is wider
    {
        m.Height = (int)((double)i.Height / (double)i.Width * (double)m.Width);
    }
    else
    {
        m.Width = (int)((double)i.Width / (double)i.Height * (double)m.Height);
    }
    args.Graphics.DrawImage(i, m);
};
pd.Print();

For Visual Studio 2019 and Visual Studio 2017 Users
For People who are missing this old feature in VS2019 (or maybe VS2017) from the old versions of Visual Studio

This feature still available, but it is NOT available by default, you have to install it separately.

1. Open VS 2019 go to Tools -> Get Tools and Features
2. Select the Individual components tab and search for Class Designer
3. Select this Component and Install it, After finish installing this component (you may need to restart visual studio)
4. Right-click on the project and select Add -> Add New Item
5. Search for 'class' word and NOW you can see Class Diagram component

see this answer also to see an image associated

Update to create a class-diagram for the whole project
I received a downvote because I did not mention how to generate a diagram for the whole project, here is how to do it (after applying the previous steps)

1. Add class diagram to the project
2. if the option Preview Selected Items is enabled in the solution explorer, disabled it temporarily, you can re-enable it later

3. open the class diagram that you created in step 2 (by double-clicking on it)
4. drag-and-drop the project from the solution explorer to the class diagram

you could be shocked by the results to the point that you can change your mind and remove your downvote (please do NOT upvote, it is enough to remove your downvote)

Use Node Version Manager (NVM)

It's a Bash script that lets you download and manage different versions of node. Full source code is here.

There is a separate project for nvm for Windows: github.com/coreybutler/nvm-windows

Below are the full steps to use NVM for multiple version of node on windows

1. download nvm-setup.zip extract and install it.
2. execute command nvm list available from cmd or gitbash or powershell, this will list all available version of node
3. use command nvm install version e.g. nvm install 12.14.0 to install on the machine
4. last once installed use nvm use version to use newer version e.g. nvm use 12.14.0

If your values are coming from the database, show selected values in that way.

<div class="form-group">
    <label for="status">Status</label>
    <select class="form-control" name="status" [(ngModel)]="category.status">
       <option [value]="1" [selected]="category.status ==1">Active</option>
       <option [value]="0" [selected]="category.status ==0">In Active</option>
    </select>

For me, the bug was in DataTables itself; The code for sorting in DataTables 1.10.9 will not check for bounds; thus if you use something like

order: [[1, 'asc']]

with an empty table, there is no row idx 1 -> this exception ensures. This happened as the data for the table was being fetched asynchronously. Initially, on page loading the dataTable gets initialized without data. It should be updated later as soon as the result data is fetched.

My solution:

// add within function _fnStringToCss( s ) in datatables.js
// directly after this line
// srcCol = nestedSort[i][0];

if(srcCol >= aoColumns.length) {
    continue;
}

// this line follows:
// aDataSort = aoColumns[ srcCol ].aDataSort;

Make sure your server is sending the font files with the right mime/type.

I recently have the same problem using nginx because some font mime types are missing from its vanilla /etc/nginx/mime.types file.

I fixed the issue adding the missing mime types in the location where I needed them like this:

location /app/fonts/ {

  #Fonts dir
  alias /var/www/app/fonts/;

  #Include vanilla types
  include mime.types;

  #Missing mime types
  types  {font/truetype ttf;}
  types  {application/font-woff woff;}
  types  {application/font-woff2 woff2;}
}

You can also check this out for extending the mime.types in nginx: extending default nginx mime.types file

Use \W which is equivalent to [^a-zA-Z0-9_]. Check the documentation, https://docs.python.org/2/library/re.html

Import re
s =  'h^&ell`.,|o w]{+orld'
replaced_string = re.sub(r'\W+', '*', s)
output: 'h*ell*o*w*orld'

update: This solution will exclude underscore as well. If you want only alphabets and numbers to be excluded, then solution by nneonneo is more appropriate.

div.style yields an object (CSSStyleDeclaration). Since it's an object, you can alternatively use the following:

div.style["top"] = "200px";
div.style["left"] = "200px";

This is useful, for example, if you need to access a "variable" property:

div.style[prop] = "200px";

Here is my approach that you may try:

import numpy as np
import matplotlib.pyplot as plt

w=10
h=10
fig=plt.figure(figsize=(8, 8))
columns = 4
rows = 5
for i in range(1, columns*rows +1):
    img = np.random.randint(10, size=(h,w))
    fig.add_subplot(rows, columns, i)
    plt.imshow(img)
plt.show()

The resulting image:

Edit 1

Since this answer is popular beyond my expectation. And I see that a small change is needed to enable flexibility for the manipulation of the individual plots. So that I offer this new version to the original code. In essence, it provides:-

1. access to individual axes of subplots
2. possibility to plot more features on selected axes/subplot

New code:

import numpy as np
import matplotlib.pyplot as plt

w = 10
h = 10
fig = plt.figure(figsize=(9, 13))
columns = 4
rows = 5

# prep (x,y) for extra plotting
xs = np.linspace(0, 2*np.pi, 60)  # from 0 to 2pi
ys = np.abs(np.sin(xs))           # absolute of sine

# ax enables access to manipulate each of subplots
ax = []

for i in range(columns*rows):
    img = np.random.randint(10, size=(h,w))
    # create subplot and append to ax
    ax.append( fig.add_subplot(rows, columns, i+1) )
    ax[-1].set_title("ax:"+str(i))  # set title
    plt.imshow(img, alpha=0.25)

# do extra plots on selected axes/subplots
# note: index starts with 0
ax[2].plot(xs, 3*ys)
ax[19].plot(ys**2, xs)

plt.show()  # finally, render the plot

The resulting plot:

Edit 2

In the previous example, the code provides access to the sub-plots with single index, which is inconvenient when the figure has many rows/columns of sub-plots. Here is an alternative of it. The code below provides access to the sub-plots with [row_index][column_index], which is more suitable for manipulation of array of many sub-plots.

import matplotlib.pyplot as plt
import numpy as np

# settings
h, w = 10, 10        # for raster image
nrows, ncols = 5, 4  # array of sub-plots
figsize = [6, 8]     # figure size, inches

# prep (x,y) for extra plotting on selected sub-plots
xs = np.linspace(0, 2*np.pi, 60)  # from 0 to 2pi
ys = np.abs(np.sin(xs))           # absolute of sine

# create figure (fig), and array of axes (ax)
fig, ax = plt.subplots(nrows=nrows, ncols=ncols, figsize=figsize)

# plot simple raster image on each sub-plot
for i, axi in enumerate(ax.flat):
    # i runs from 0 to (nrows*ncols-1)
    # axi is equivalent with ax[rowid][colid]
    img = np.random.randint(10, size=(h,w))
    axi.imshow(img, alpha=0.25)
    # get indices of row/column
    rowid = i // ncols
    colid = i % ncols
    # write row/col indices as axes' title for identification
    axi.set_title("Row:"+str(rowid)+", Col:"+str(colid))

# one can access the axes by ax[row_id][col_id]
# do additional plotting on ax[row_id][col_id] of your choice
ax[0][2].plot(xs, 3*ys, color='red', linewidth=3)
ax[4][3].plot(ys**2, xs, color='green', linewidth=3)

plt.tight_layout(True)
plt.show()

The resulting plot:

Early versions of unix measured system time in 1/60 s intervals. This meant that a 32-bit unsigned integer could only represent a span of time less than 829 days. For this reason, the time represented by the number 0 (called the epoch) had to be set in the very recent past. As this was in the early 1970s, the epoch was set to 1971-1-1.

Later, the system time was changed to increment every second, which increased the span of time that could be represented by a 32-bit unsigned integer to around 136 years. As it was no longer so important to squeeze every second out of the counter, the epoch was rounded down to the nearest decade, thus becoming 1970-1-1. One must assume that this was considered a bit neater than 1971-1-1.

Note that a 32-bit signed integer using 1970-1-1 as its epoch can represent dates up to 2038-1-19, on which date it will wrap around to 1901-12-13.

First of all you missed ScriptService attribute to add in webservice.

[ScriptService]

After then try following method to call webservice via JSON.

        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        httpWebRequest.ContentType = "application/json; charset=utf-8";
        httpWebRequest.Method = "POST";            

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = "{\"x\":\"true\"}";

            streamWriter.Write(json);
            streamWriter.Flush();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();

In order to display time in a human-readable format, use the function millisToShortDHMS(long duration).

YES!

But you can't do it in the way you may immediately think, because you cant animate or create a transition around the properties you'd otherwise rely on (e.g. display, or changing dimensions and setting to overflow:hidden) in order to correctly hide the element and prevent it from taking up visible space.

Therefore, create an animation for the elements in question, and simply toggle visibility:hidden; after 5 seconds, whilst also setting height and width to zero to prevent the element from still occupying space in the DOM flow.

If you have tried all these solutions, esp. increasing max_allowed_packet up to the maximum supported amount of 1GB and you are still seeing these errors, it might be that your server literally does not have enough free RAM memory available...

The solution = upgrade your server to more RAM memory, and try again.

Note: I'm surprised this simple solution has not been mentioned after 8+ years of discussion on this thread... sometimes we developers tend to overthink things.

In my case tomcat was configured to start not on localhost(guess it came from servers.xml connector entry) so Eclipse fails to find it running after start. Changed Host name on Servers tab to my 192.168.xxx.yyy ip.

Had the same error message, though tomcat did start sucessfully, but then Eclipse shuts it down.

The best way to skip the first item(s) is:

from itertools import islice
for car in islice(cars, 1, None):
    # do something

islice in this case is invoked with a start-point of 1, and an end point of None, signifying the end of the iterator.

To be able to skip items from the end of an iterable, you need to know its length (always possible for a list, but not necessarily for everything you can iterate on). for example, islice(cars, 1, len(cars)-1) will skip the first and last items in the cars list.

What's wrong with just simply using a single, simple UPDATE statement??

UPDATE dbo.Coupon
SET NoofUses = (SELECT COUNT(*) FROM dbo.CouponUse WHERE Couponid = dbo.Coupon.ID)

That's all that's needed ! No messy and complicated cursor, no looping, no RBAR (row-by-agonizing-row) processing ..... just a nice, simple, clean set-based SQL statement.

I get this error very often for some reason when doing "ionic cordova run android" and running on an emulator. What works for me is to end the "adb.exe" process and re-run. Sometimes that also doesn't work and what I do is exit the emulator and in android studio do a "Cold Boot" on the emulator.

Place hidden UILabel underneath your textview. Label lines = 0. Set constraints of UITextView to be equal to the UILabel (centerX, centerY, width, height). Works even if you leave scroll behaviour of textView.

The root of it all is to make sure that the requests are coming from the actual users of the site. A csrf token is generated for the forms and Must be tied to the user's sessions. It is used to send requests to the server, in which the token validates them. This is one way of protecting against csrf, another would be checking the referrer header.

According to this discussion: http://bytes.com/topic/python/answers/464012-objects-list-index

Loop counter iteration

The current idiom for looping over the indices makes use of the built-in range function:

for i in range(len(sequence)):
    # work with index i

Looping over both elements and indices can be achieved either by the old idiom or by using the new zip built-in function:

for i in range(len(sequence)):
    e = sequence[i]
    # work with index i and element e

or

for i, e in zip(range(len(sequence)), sequence):
    # work with index i and element e

You should use "readonly" instead like:

$("input[type='text']").attr("readonly", "true");

There is no difference between both, AS is just a more explicit way of mentioning the alias which is good because some dependent libraries depends on this small keyword. e.g. JDBC 4.0. Depend on use of it, different behaviour can be observed.

See this. I would always suggest to use the full form of semantic to avoid such issues.

When you go to a stream url, you get offered a file. feed this file to a parser to extract the contents out of it. the file is (usually) plain text and contains the url to play.

Make sure you import csv file using Pandas

import pandas as pd

condition = pd.isnull(data[i][j])

Attach an event listener to the form using .addEventListener() and then call the .preventDefault() method on event:

const element = document.querySelector('form');_x000D_
element.addEventListener('submit', event => {_x000D_
  event.preventDefault();_x000D_
  // actual logic, e.g. validate the form_x000D_
  console.log('Form submission cancelled.');_x000D_
});

<form>_x000D_
  <button type="submit">Submit</button>_x000D_
</form>

I think it's a better solution than defining a submit event handler inline with the onsubmit attribute because it separates webpage logic and structure. It's much easier to maintain a project where logic is separated from HTML. See: Unobtrusive JavaScript.

Using the .onsubmit property of the form DOM object is not a good idea because it prevents you from attaching multiple submit callbacks to one element. See addEventListener vs onclick .

If you need performance, you might take a look at Grph. The library is developed in the French University and CNRS/Inria.

http://www.i3s.unice.fr/~hogie/grph/

The project is active and reactive support is provided!

1. First, let's see what this does:

   Arrays.asList(ia)
   

   It takes an array ia and creates a wrapper that implements List<Integer>, which makes the original array available as a list. Nothing is copied and all, only a single wrapper object is created. Operations on the list wrapper are propagated to the original array. This means that if you shuffle the list wrapper, the original array is shuffled as well, if you overwrite an element, it gets overwritten in the original array, etc. Of course, some List operations aren't allowed on the wrapper, like adding or removing elements from the list, you can only read or overwrite the elements.

   Note that the list wrapper doesn't extend ArrayList - it's a different kind of object. ArrayLists have their own, internal array, in which they store their elements, and are able to resize the internal arrays etc. The wrapper doesn't have its own internal array, it only propagates operations to the array given to it.

2. On the other hand, if you subsequently create a new array as

   new ArrayList<Integer>(Arrays.asList(ia))
   

   then you create new ArrayList, which is a full, independent copy of the original one. Although here you create the wrapper using Arrays.asList as well, it is used only during the construction of the new ArrayList and is garbage-collected afterwards. The structure of this new ArrayList is completely independent of the original array. It contains the same elements (both the original array and this new ArrayList reference the same integers in memory), but it creates a new, internal array, that holds the references. So when you shuffle it, add, remove elements etc., the original array is unchanged.

Dependency required for jersey restful service and Tomcat is the server. where ${jersey.version} is 2.29.1

    <dependency>
        <groupId>javax.enterprise</groupId>
        <artifactId>cdi-api</artifactId>
        <version>2.0.SP1</version>
        <scope>provided</scope>

        <artifactId>jersey-hk2</artifactId>
        <version>${jersey.version}</version>
    </dependency>

The basic code will be as follows:

@RequestScoped
@Path("test")
public class RESTEndpoint {

   @GET
   public String getMessage() {

OP stated he didn't want to modify the code for the buttons. This is the least-intrusive answer I could come up with using the other answers as a guide. It doesn't require additional hidden fields, allows you to leave the button code intact (sometimes you don't have access to what generates it), and gives you the info you were looking for from anywhere in your code...which button was used to submit the form. I haven't evaluated what happens if the user uses the Enter key to submit the form, rather than clicking.

<script language="javascript" type="text/javascript">

    var initiator = '';
    $(document).ready(function() {
        $(":submit").click(function() { initiator = this.name });
    });

</script>

Then you have access to the 'initiator' variable anywhere that might need to do the checking. Hope this helps.

Use the DATEPART function to extract the month from the date.

So you would do something like this:

SELECT DATEPART(month, Closing_Date) AS Closing_Month, COUNT(Status) AS TotalCount
FROM t
GROUP BY DATEPART(month, Closing_Date)

Very simple solution and test for JavaScript!

ToBase64 = function (u8) {
    return btoa(String.fromCharCode.apply(null, u8));
}

FromBase64 = function (str) {
    return atob(str).split('').map(function (c) { return c.charCodeAt(0); });
}

var u8 = new Uint8Array(256);
for (var i = 0; i < 256; i++)
    u8[i] = i;

var b64 = ToBase64(u8);
console.debug(b64);
console.debug(FromBase64(b64));

1: I have downloaded the mysql-connector-java-5.1.24-bin.jar

Okay.

2: I have created a lib folder in my project and put the jar in there.

Wrong. You need to drop JAR in /WEB-INF/lib folder. You don't need to create any additional folders.

3: properties of project->build path->add JAR and selected the JAR above.

Unnecessary. Undo it all to avoid possible conflicts.

4: I still get java.sql.SQLException: No suitable driver found for jdbc:mysql//localhost:3306/mysql

This exception can have 2 causes:

1. JDBC driver is not in runtime classpath. This is to be solved by doing 2) the right way.

2. JDBC URL is not recognized by any of the loaded JDBC drivers. Indeed, the JDBC URL is wrong, there should as per the MySQL JDBC driver documentation be another colon between the scheme and the host.

   jdbc:mysql://localhost:3306/mysql

Following script will extract frames every half a second of all videos in folder. (Works on python 3.7)

import cv2
import os
listing = os.listdir(r'D:/Images/AllVideos')
count=1
for vid in listing:
    vid = r"D:/Images/AllVideos/"+vid
    vidcap = cv2.VideoCapture(vid)
    def getFrame(sec):
        vidcap.set(cv2.CAP_PROP_POS_MSEC,sec*1000)
        hasFrames,image = vidcap.read()
        if hasFrames:
            cv2.imwrite("D:/Images/Frames/image"+str(count)+".jpg", image) # Save frame as JPG file
        return hasFrames
    sec = 0
    frameRate = 0.5 # Change this number to 1 for each 1 second
    
    success = getFrame(sec)
    while success:
        count = count + 1
        sec = sec + frameRate
        sec = round(sec, 2)
        success = getFrame(sec)

Another solution is setting the size attribute on the select box.

Thus taking back control of the styling of the dropdown from the Apple style and displaying Font Awesome Icons correctly.

DECLARE @JCnt int=null
SEt @JCnt=(SELECT COUNT( ISNUll(EmpCode,0)) FROM tbl_Employees WHERE EmpCode=1  )

UPDATE #TempCode
SET janCA= CASE WHEN @JCnt>0 THEN (SELECT SUM (ISNUll(Amount,0)) FROM tbl_Salary WHERE Code=1 )ELSE 0 END
WHERE code=1

For me, I changed class='carousel-item' to class='item' like this

<div class="item">
    <img class="img-responsive" src="..." alt="...">
</div>

Is there a way to declare first and then initialize an array in C?

There is! but not using the method you described.

You can't initialize with a comma separated list, this is only allowed in the declaration. You can however initialize with...

myArray[0] = 1;
myArray[1] = 2;
...

or

for(int i = 1; i <= SIZE; i++)
{
  myArray[i-1] = i;
}

Rather than deleting or renaming this file:

1. Close SQL Server Management Studio.
2. Find the appropriate file (see the other posts).
3. Open the .bin in a text/hex editior like NotePad++.
4. Search for the name of one of the servers and identify the line number.
5. Make a copy of the .bin/.dat file.
6. Delete that line. Make sure you delete the entire line, it's possible if you have many the line could wrap.
7. Open SQL Server Management Studio. Your dropdown will be blank.

I'd like to expand on Obertklep's answer. In his example it is an NPM module called body-parser which is doing most of the work. Where he puts req.body.name, I believe he/she is using body-parser to get the contents of the name attribute(s) received when the form is submitted.

If you do not want to use Express, use querystring which is a built-in Node module. See the answers in the link below for an example of how to use querystring.

It might help to look at this answer, which is very similar to your quest.

(int)99.99999

It will be 99. Casting a double to an int does not round, it'll discard the fraction part.

Agree with neubert about the DECLARE statements, this will fix syntax error. But I would suggest you to avoid using openning cursors, they may be slow.

For your task: use INSERT...SELECT statement which will help you to copy data from one table to another using only one query.

INSERT ... SELECT Syntax.

Sweet and simple:

1. Open the repository
2. Navigate to settings
3. Scroll to the bottom of the page
4. Click on delete
5. Confirm names of the Repository to delete
6. Click on delete

//Element[@attribute1="abc" and @attribute2="xyz" and .="Data"]

The reason why I add this answer is that I want to explain the relationship of . and text() .

The first thing is when using [], there are only two types of data:

1. [number] to select a node from node-set
2. [bool] to filter a node-set from node-set

In this case, the value is evaluated to boolean by function boolean(), and there is a rule:

Filters are always evaluated with respect to a context.

When you need to compare text() or . with a string "Data", it first uses string() function to transform those to string type, than gets a boolean result.

There are two important rule about string():

1. The string() function converts a node-set to a string by returning the string value of the first node in the node-set, which in some instances may yield unexpected results.

   text() is relative path that return a node-set contains all the text node of current node(context node), like ["Data"]. When it is evaluated by string(["Data"]), it will return the first node of node-set, so you get "Data" only when there is only one text node in the node-set.

2. If you want the string() function to concatenate all child text, you must then pass a single node instead of a node-set.

   For example, we get a node-set ['a', 'b'], you can pass there parent node to string(parent), this will return 'ab', and of cause string(.) in you case will return an concatenated string "Data".

Both way will get same result only when there is a text node.

If you keep grabbing bits from your data, you might want to use a bitfield. You'll just have to set up a struct and load it with only ones and zeroes:

struct bitfield{
    unsigned int bit : 1
}
struct bitfield *bitstream;

then later on load it like this (replacing char with int or whatever data you are loading):

long int i;
int j, k;
unsigned char c, d;

bitstream=malloc(sizeof(struct bitfield)*charstreamlength*sizeof(char));
for (i=0; i<charstreamlength; i++){
    c=charstream[i];
    for(j=0; j < sizeof(char)*8; j++){
        d=c;
        d=d>>(sizeof(char)*8-j-1);
        d=d<<(sizeof(char)*8-1);
        k=d;
        if(k==0){
            bitstream[sizeof(char)*8*i + j].bit=0;
        }else{
            bitstream[sizeof(char)*8*i + j].bit=1;
        }
    }
}

Then access elements:

bitstream[bitpointer].bit=...

or

...=bitstream[bitpointer].bit

All of this is assuming are working on i86/64, not arm, since arm can be big or little endian.

2 things.

• The query has to complete on sql server before the return value is sent.

• The results have to be captured and then finish executing before the return value gets to the object.

In English, finish the work and then retrieve the value.

this will not work:

                cmm.ExecuteReader();
                int i = (int) cmm.Parameters["@RETURN_VALUE"].Value;

This will work:

                        SqlDataReader reader = cmm.ExecuteReader();
                        reader.Close();

                        foreach (SqlParameter prm in cmd.Parameters)
                        {
                           Debug.WriteLine("");
                           Debug.WriteLine("Name " + prm.ParameterName);
                           Debug.WriteLine("Type " + prm.SqlDbType.ToString());
                           Debug.WriteLine("Size " + prm.Size.ToString());
                           Debug.WriteLine("Direction " + prm.Direction.ToString());
                           Debug.WriteLine("Value " + prm.Value);

                        }

if you are not sure check the value of the parameter before during and after the results have been processed by the reader.

For implementing the breadth first search, you should use a queue. You should push the children of a node to the queue (left then right) and then visit the node (print data). Then, yo should remove the node from the queue. You should continue this process till the queue becomes empty. You can see my implementation of the BFS here: https://github.com/m-vahidalizadeh/foundations/blob/master/src/algorithms/TreeTraverse.java

The problem is that you're trying to print an unicode character to a possibly non-unicode terminal. You need to encode it with the 'replace option before printing it, e.g. print ch.encode(sys.stdout.encoding, 'replace').

There is no forumula, as street names and cities are essentially handed out randomly. The address needs to be looked up in a database. Alternatively, you can look up a zip code in a database for the region that the zip code is for.

You didn't mention a country, so I'm going to assume you just want addresses in the USA. There are numerous databases you can use, some free, some not.

You can also use the Google Maps API to have them look up an address in their database for you. That is probably the easiest solution, but requires your application to have a working internet connection at all times.

Your system does not have a GUI manager. Happens mostly in Solaris/Linux boxes. If you are using GUI in them make sure that you have a GUI manager installed and you may also want to google through the DISPLAY variable.

Try this:

case $VAR in
normal)
    echo "This doesn't do fallthrough"
    ;;
special)
    echo -n "This does "
    ;&
fallthrough)
    echo "fall-through"
    ;;
esac

you have to add fulltext index on specific fields you want to search.

ALTER TABLE news ADD FULLTEXT(headline, story);

where "news" is your table and "headline, story" fields you wont to enable for fulltext search

def pearson(x,y):
  n=len(x)
  vals=range(n)

  sumx=sum([float(x[i]) for i in vals])
  sumy=sum([float(y[i]) for i in vals])

  sumxSq=sum([x[i]**2.0 for i in vals])
  sumySq=sum([y[i]**2.0 for i in vals])

  pSum=sum([x[i]*y[i] for i in vals])
  # Calculating Pearson correlation
  num=pSum-(sumx*sumy/n)
  den=((sumxSq-pow(sumx,2)/n)*(sumySq-pow(sumy,2)/n))**.5
  if den==0: return 0
  r=num/den
  return r

Using Alamofire worked out for me on Swift 3:

Step 1:

Integrate using pods.

pod 'Alamofire', '~> 4.4'

pod 'AlamofireImage', '~> 3.3'

Step 2:

import AlamofireImage

import Alamofire

Step 3:

Alamofire.request("https://httpbin.org/image/png").responseImage { response in

if let image = response.result.value {
    print("image downloaded: \(image)")
self.myImageview.image = image
}
}

You should also try -ggdb instead of -g if you're compiling for Android!

Suppose you want to add those flags (better to declare them in a constant):

SET(GCC_COVERAGE_COMPILE_FLAGS "-fprofile-arcs -ftest-coverage")
SET(GCC_COVERAGE_LINK_FLAGS    "-lgcov")

There are several ways to add them:

1. The easiest one (not clean, but easy and convenient, and works only for compile flags, C & C++ at once):

   add_definitions(${GCC_COVERAGE_COMPILE_FLAGS})
   

2. Appending to corresponding CMake variables:

   SET(CMAKE_CXX_FLAGS  "${CMAKE_CXX_FLAGS} ${GCC_COVERAGE_COMPILE_FLAGS}")
   SET(CMAKE_EXE_LINKER_FLAGS  "${CMAKE_EXE_LINKER_FLAGS} ${GCC_COVERAGE_LINK_FLAGS}")
   

3. Using target properties, cf. doc CMake compile flag target property and need to know the target name.

   get_target_property(TEMP ${THE_TARGET} COMPILE_FLAGS)
   if(TEMP STREQUAL "TEMP-NOTFOUND")
     SET(TEMP "") # Set to empty string
   else()
     SET(TEMP "${TEMP} ") # A space to cleanly separate from existing content
   endif()
   # Append our values
   SET(TEMP "${TEMP}${GCC_COVERAGE_COMPILE_FLAGS}" )
   set_target_properties(${THE_TARGET} PROPERTIES COMPILE_FLAGS ${TEMP} )
   

Right now I use method 2.

You can use xlrd.

From its documentation, you can read that dates are always stored as numbers; however, you can use xldate_as_tuple to convert it to a python date.

Note: the version on the PyPI seems more up-to-date than the one available on xlrd's website.

You've already got some good answers, but I thought you might be interested in a bit of the background too.

Firstly you're missing the quotes. It should be:

"hello".encode("hex")

Secondly this codec hasn't been ported to Python 3.1. See here. It seems that they haven't yet decided whether or not these codecs should be included in Python 3 or implemented in a different way.

If you look at the diff file attached to that bug you can see the proposed method of implementing it:

import binascii
output = binascii.b2a_hex(input)

Here's a function that is also based on cloneNode, but with an option to clone only the parent node and move all the children (to preserve their event listeners):

function recreateNode(el, withChildren) {
  if (withChildren) {
    el.parentNode.replaceChild(el.cloneNode(true), el);
  }
  else {
    var newEl = el.cloneNode(false);
    while (el.hasChildNodes()) newEl.appendChild(el.firstChild);
    el.parentNode.replaceChild(newEl, el);
  }
}

Remove event listeners on one element:

recreateNode(document.getElementById("btn"));

Remove event listeners on an element and all of its children:

recreateNode(document.getElementById("list"), true);

If you need to keep the object itself and therefore can't use cloneNode, then you have to wrap the addEventListener function and track the listener list by yourself, like in this answer.

Offering an interactive sort handling multiple columns is nothing trivial.

Unless you want to write a good amount of code handling logic for multiple row clicks, editing and refreshing page content, managing sort algorithms for large tables… then you really are better off adopting a plug-in.

tablesorter, (with updates by Mottie) is my favorite. It’s easy to get going and very customizable. Just add the class tablesorter to the table you want to sort, then invoke the tablesorter plugin in a document load event:

$(function(){
    $("#myTable").tablesorter();
});

You can browse the documentation to learn about advanced features.

If you are using AngularJS, you can use a custom directive for easy access:

define(['angular'], function () {
    angular.module("selectionHelper", [])
    .directive('selectOnClick', function () {
        return {
            restrict: 'A',
            link: function (scope, element, attrs) {                
                element.on('click', function () {
                    this.select();
                });
            }
        };
    });
});

Now one can just use it like this:

<input type="text" select-on-click ... />

The sample is with requirejs - so the first and the last line can be skipped if using something else.

In many cases an element must be positioned for z-index to work.

Indeed, applying position: relative to the elements in the question would likely solve the problem (but there's not enough code provided to know for sure).

Actually, position: fixed, position: absolute and position: sticky will also enable z-index, but those values also change the layout. With position: relative the layout isn't disturbed.

Essentially, as long as the element isn't position: static (the default setting) it is considered positioned and z-index will work.

Many answers to "Why isn't z-index working?" questions assert that z-index only works on positioned elements. As of CSS3, this is no longer true.

Elements that are flex items or grid items can use z-index even when position is static.

From the specs:

4.3. Flex Item Z-Ordering

Flex items paint exactly the same as inline blocks, except that order-modified document order is used in place of raw document order, and z-index values other than auto create a stacking context even if position is static.

5.4. Z-axis Ordering: the z-index property

The painting order of grid items is exactly the same as inline blocks, except that order-modified document order is used in place of raw document order, and z-index values other than auto create a stacking context even if position is static.

Here's a demonstration of z-index working on non-positioned flex items: https://jsfiddle.net/m0wddwxs/

Follow the below steps,

1. npm install -g http-server, install the http-server in angular project.
2. Go to file location which needs to be accessed and open cmd prompt, use cmd http-server ./
3. Access any of the paths with port number in browser(ex: 120.0.0.1:8080) 4.now in your angular application use the path "http://120.0.0.1:8080/filename" Worked fine for me

I have edited the "Best answer" code, though I found a useful thing that was missing. This is will also track the ip of a user if they are using a Proxy or simply if the server has nginx installed as a proxy reverser.

I added this code to his script at the top of the function:

function getRealIpAddr()
{
    if (!empty($_SERVER['HTTP_CLIENT_IP']))   //check ip from share internet
    {
      $ip=$_SERVER['HTTP_CLIENT_IP'];
    }
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //to check ip is pass from proxy
    {
      $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}
$adresseip = getRealIpAddr();

Afther that I edited his code.

Find the line that says the following:

// get the user name if it is logged, or the visitors IP (and add the identifier)

    $uvon = isset($_SESSION['nume']) ? $_SESSION['nume'] : $_SERVER['SERVER_ADDR']. $vst_id;

and replace it with this:

$uvon = isset($_SESSION['nume']) ? $_SESSION['nume'] : $adresseip. $vst_id;

This will work.

Here is the full code if anything happens:

    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}
$adresseip = getRealIpAddr();

Haven't tested this on the Sql script yet.

Edit

As WhatsApp put some effort into improving their encryption system, getting the data is not that easy anymore. With newer versions of WhatsApp it is no longer possible to use adb backup. Apps can deny backups and the WhatsApp client does that. If you happen to have a rooted phone, you can use a root shell to get the unencrypted database file.

If you do not have root, you can still decrypt the data if you have an old WhatsApp APK. Find a version that still allows backups. Then you can make a backup of the app's data folder, which will contain an encryption key named, well, key.

Now you'll need the encrypted database. Use a file explorer of your choice or, if you like the command line more, use adb:

adb pull /sdcard/WhatsApp/Databases/msgstore.db.crypt12

Using the two files, you could now use https://gitlab.com/digitalinternals/whatsapp-crypt12 to get the plain text database. It is no longer possible to use Linux board tools like openssl because WhatsApp seems to use a modified version of the Spongy Castle API for cryptography that openssl does not understand.

Original Answer (only for the old crypt7)

As whatsapp is now using the crypt7 format, it is not that easy to get and decrypt the database anymore. There is a working approach using ADB and USB debugging.

You can either get the encryption keys via ADB and decrypt the message database stored on /sdcard, or you just get the plain version of the database via ADB backup, what seems to be the easier option.

To get the database, do the following:

Connect your Android phone to your computer. Now run

adb backup -f whatsapp_backup.ab -noapk com.whatsapp

to backup all files WhatsApp has created in its private folder.
You will get a zlib compressed file using tar format with some ADB headers. We need to get rid of those headers first as they confuse the decompression command:

dd if=whatsapp_backup.ab ibs=1 skip=24 of=whatsapp_backup.ab.nohdr

The file can now be decompressed:

cat whatsapp_backup.ab.nohdr | python -c "import zlib,sys;sys.stdout.write(zlib.decompress(sys.stdin.read()))" 1> whatsapp_backup.tar

This command runs Python and decompresses the file using zlib to whatsapp_backup.tar
Now we can unTAR the file:

tar xf whatsapp_backup.tar

The archive is now extracted to your current working directory and you can find the databases (msgstore.db and wa.db) in apps/com.whatsapp/db/

You could also use ld option -Bdynamic

gcc <objectfiles> -static -lstatic1 -lstatic2 -Wl,-Bdynamic -ldynamic1 -ldynamic2

All libraries after it (including system ones linked by gcc automatically) will be linked dynamically.

Use api Is there an API to force Facebook to scrape a page again?

$furl = 'https://graph.facebook.com';

$ch = curl_init();

curl_setopt( $ch, CURLOPT_URL, $furl );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_POST, true );
$params = array(
    'id' => '<update_url>',
    'scrape' => true );
$data = http_build_query( $params );
curl_setopt( $ch, CURLOPT_POSTFIELDS, $data );

curl_exec( $ch );
$httpCode = curl_getinfo( $ch, CURLINFO_HTTP_CODE );

If you are on Unix, you could use the access time of the files in there. Just enable access time for your filesystem, then run a clean build of all your projects you would like to keep dependencies for and then do something like this (UNTESTED!):

find ~/.m2 -amin +5 -iname '*.pom' | while read pom; do parent=`dirname "$pom"`; rm -Rf "$parent"; done

This will find all *.pom files which have last been accessed more than 5 minutes ago (assuming you started your builds max 5 minutes ago) and delete their directories.

Add "echo " before the rm to do a 'dry-run'.

try {
    File img = new File("somefile.png");
    BufferedImage image = ImageIO.read(img ); 
    System.out.println(image);
} catch (IOException e) { 
    e.printStackTrace(); 
}

Example output for my image file:

BufferedImage@5d391d: type = 5 ColorModel: #pixelBits = 24 
numComponents = 3 color 
space = java.awt.color.ICC_ColorSpace@50a649 
transparency = 1 
has alpha = false 
isAlphaPre = false 
ByteInterleavedRaster: 
width = 800 
height = 600 
#numDataElements 3 
dataOff[0] = 2

You can run System.out.println(object); on just about any object and get some information about it.

It sounds like you can pick and choose. If you pick float, you may lose 11 digits of precision. If that's acceptable, go for it -- apparently the Linq designers thought this to be a good tradeoff.

However, if your application needs those extra digits, use decimal. Decimal (implemented correctly) is way more accurate than a float anyway -- no messy translation from base 10 to base 2 and back.

List<string> test1 = new List<string> { "@bob.com", "@tom.com" };
List<string> test2 = new List<string> { "[email protected]", "[email protected]", "[email protected]" };

var result = (from t2 in test2
              where test1.Any(t => t2.Contains(t)) == false
              select t2);

If query form is what you want to use, this is legible and more or less as "performant" as this could be.

What i mean is that what you are trying to do is an O(N*M) algorithm, that is, you have to traverse N items and compare them against M values. What you want is to traverse the first list only once, and compare against the other list just as many times as needed (worst case is when the email is valid since it has to compare against every black listed domain).

from t2 in test we loop the email list once.

test1.Any(t => t2.Contains(t)) == false we compare with the blacklist and when we found one match return (hence not comparing against the whole list if is not needed)

select t2 keep the ones that are clean.

So this is what I would use.

Your syntax is slightly wrong. Say:

*/15 * * * * command
  |
  |--> `*/15` would imply every 15 minutes.

* indicates that the cron expression matches for all values of the field.

/ describes increments of ranges.

Check out history.js. There is a html 5 statechange event and you can listen to it.

Modern linux systems will normally only have entries in /dev for devices that exist, so going through hda* and sda* as you suggest would work fairly well.

Otherwise, there may be something in /proc you can use. From a quick look in there, I'd have said /proc/partitions looks like it could do what you need.

Answer if you only want to use for each loop ..

for (WebElement s : options) {
    int i = options.indexOf(s);
    System.out.println(options.get(i).getText());
}

Just add a STYLE line and your progress becomes horizontal:

<ProgressBar
        style="?android:attr/progressBarStyleHorizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/progress"
        android:layout_centerHorizontal="true"      
        android:layout_centerVertical="true"      
        android:max="100" 
        android:progress="45"/>

if you have control over the query which builds the jQuery object, use :eq()

$("div:eq(2)")

If you don't have control over it (for example, it's being passed from another function or something), then use .eq()

var $thirdElement = $jqObj.eq(2);

Or if you want a section of them (say, the third, fourth and fifth elements), use .slice()

var $third4th5thElements = $jqObj.slice(2, 5);

What is SQL JOIN ?

SQL JOIN is a method to retrieve data from two or more database tables.

What are the different SQL JOINs ?

There are a total of five JOINs. They are :

  1. JOIN or INNER JOIN
  2. OUTER JOIN

     2.1 LEFT OUTER JOIN or LEFT JOIN
     2.2 RIGHT OUTER JOIN or RIGHT JOIN
     2.3 FULL OUTER JOIN or FULL JOIN

  3. NATURAL JOIN
  4. CROSS JOIN
  5. SELF JOIN

1. JOIN or INNER JOIN :

In this kind of a JOIN, we get all records that match the condition in both tables, and records in both tables that do not match are not reported.

In other words, INNER JOIN is based on the single fact that: ONLY the matching entries in BOTH the tables SHOULD be listed.

Note that a JOIN without any other JOIN keywords (like INNER, OUTER, LEFT, etc) is an INNER JOIN. In other words, JOIN is a Syntactic sugar for INNER JOIN (see: Difference between JOIN and INNER JOIN).

2. OUTER JOIN :

OUTER JOIN retrieves

Either, the matched rows from one table and all rows in the other table Or, all rows in all tables (it doesn't matter whether or not there is a match).

There are three kinds of Outer Join :

2.1 LEFT OUTER JOIN or LEFT JOIN

This join returns all the rows from the left table in conjunction with the matching rows from the right table. If there are no columns matching in the right table, it returns NULL values.

2.2 RIGHT OUTER JOIN or RIGHT JOIN

This JOIN returns all the rows from the right table in conjunction with the matching rows from the left table. If there are no columns matching in the left table, it returns NULL values.

2.3 FULL OUTER JOIN or FULL JOIN

This JOIN combines LEFT OUTER JOIN and RIGHT OUTER JOIN. It returns rows from either table when the conditions are met and returns NULL value when there is no match.

In other words, OUTER JOIN is based on the fact that: ONLY the matching entries in ONE OF the tables (RIGHT or LEFT) or BOTH of the tables(FULL) SHOULD be listed.

Note that `OUTER JOIN` is a loosened form of `INNER JOIN`.

3. NATURAL JOIN :

It is based on the two conditions :

1. the JOIN is made on all the columns with the same name for equality.
2. Removes duplicate columns from the result.

This seems to be more of theoretical in nature and as a result (probably) most DBMS don't even bother supporting this.

4. CROSS JOIN :

It is the Cartesian product of the two tables involved. The result of a CROSS JOIN will not make sense in most of the situations. Moreover, we won't need this at all (or needs the least, to be precise).

5. SELF JOIN :

It is not a different form of JOIN, rather it is a JOIN (INNER, OUTER, etc) of a table to itself.

JOINs based on Operators

Depending on the operator used for a JOIN clause, there can be two types of JOINs. They are

1. Equi JOIN
2. Theta JOIN

1. Equi JOIN :

For whatever JOIN type (INNER, OUTER, etc), if we use ONLY the equality operator (=), then we say that the JOIN is an EQUI JOIN.

2. Theta JOIN :

This is same as EQUI JOIN but it allows all other operators like >, <, >= etc.

Many consider both EQUI JOIN and Theta JOIN similar to INNER, OUTER etc JOINs. But I strongly believe that its a mistake and makes the ideas vague. Because INNER JOIN, OUTER JOIN etc are all connected with the tables and their data whereas EQUI JOIN and THETA JOIN are only connected with the operators we use in the former.

Again, there are many who consider NATURAL JOIN as some sort of "peculiar" EQUI JOIN. In fact, it is true, because of the first condition I mentioned for NATURAL JOIN. However, we don't have to restrict that simply to NATURAL JOINs alone. INNER JOINs, OUTER JOINs etc could be an EQUI JOIN too.

#footer ul li {
  position: relative;
  opacity: 0.99;
}

#footer ul li::before {
  content: "";
  position: absolute;
  width: 100%;
  height: 100%;
  z-index: -1;
  background: url(/images/arrow.png) no-repeat 0 50%;
  opacity: 0.5;
}

Hack with opacity .99 (less than 1) creates z-index context so you can not worry about global z-index values. (Try to remove it and see what happens in the next demo where parent wrapper has positive z-index.)
If your element already has z-index, then you don't need this hack.

Demo of this technique.

As others have already mentioned, HTML 4 requires the <style> tag to be placed in the <head> section (even though most browsers allow <style> tags within the body).

However, HTML 5 includes the scoped attribute (see update below), which allows you to create style sheets that are scoped within the parent element of the <style> tag. This also enables you to place <style> tags within the <body> element:

<!DOCTYPE html>
<html>
<head></head>
<body>

<div id="scoped-content">
    <style type="text/css" scoped>
        h1 { color: red; } 
    </style>

    <h1>Hello</h1>
</div>

    <h1>
      World
    </h1>

</body>
</html>

If you render the above code in an HTML-5 enabled browser that supports scoped, you will see the limited scope of the style sheet.

There's just one major caveat...

At the time I'm writing this answer (May, 2013) almost no mainstream browser currently supports the scoped attribute. (Although apparently developer builds of Chromium support it.)

HOWEVER, there is an interesting implication of the scoped attribute that pertains to this question. It means that future browsers are mandated via the standard to allow <style> elements within the <body> (as long as the <style> elements are scoped.)

So, given that:

• Almost every existing browser currently ignores the scoped attribute
• Almost every existing browser currently allows <style> tags within the <body>
• Future implementations will be required to allow (scoped) <style> tags within the <body>

...then there is literally no harm * in placing <style> tags within the body, as long as you future proof them with a scoped attribute. The only problem is that current browsers won't actually limit the scope of the stylesheet - they'll apply it to the whole document. But the point is that, for all practical purposes, you can include <style> tags within the <body> provided that you:

• Future-proof your HTML by including the scoped attribute
• Understand that as of now, the stylesheet within the <body> will not actually be scoped (because no mainstream browser support exists yet)

* except of course, for pissing off HTML validators...

Finally, regarding the common (but subjective) claim that embedding CSS within HTML is poor practice, it should be noted that the whole point of the scoped attribute is to accommodate typical modern development frameworks that allow developers to import chunks of HTML as modules or syndicated content. It is very convenient to have embedded CSS that only applies to a particular chunk of HTML, in order to develop encapsulated, modular components with specific stylings.

Update as of Feb 2019, according to the Mozilla documentation, the scoped attribute is deprecated. Chrome stopped supporting it in version 36 (2014) and Firefox in version 62 (2018). In both cases, the feature had to be explicitly enabled by the user in the browsers' settings. No other major browser ever supported it.

I'm quite a beginner in Python and I found the answer of Anand was very good but quite complicated to me, so I try to reformulate :

1) insert and append methods are not specific to sys.path and as in other languages they add an item into a list or array and :
* append(item) add item to the end of the list,
* insert(n, item) inserts the item at the nth position in the list (0 at the beginning, 1 after the first element, etc ...).

2) As Anand said, python search the import files in each directory of the path in the order of the path, so :
* If you have no file name collisions, the order of the path has no impact,
* If you look after a function already defined in the path and you use append to add your path, you will not get your function but the predefined one.

But I think that it is better to use append and not insert to not overload the standard behaviour of Python, and use non-ambiguous names for your files and methods.

Ranking by stars or forks is not working. Each promoted or created by a famous company repository is popular at the beginning. Also it is possible to have a number of them which are in trend right now (publications, marketing, events). It doesn't mean that those repositories are useful/popular.

The gitmostwanted.com project (repo at github) analyses GH Archive data in order to highlight the most interesting repositories and exclude others. Just compare the results with mentioned resources.

This is a follow up to the answer given by @EricWoodruff.

You could use netInfo's getExtraInfo() to get wifi SSID.

if (WifiManager.NETWORK_STATE_CHANGED_ACTION.equals (action)) {
    NetworkInfo netInfo = intent.getParcelableExtra (WifiManager.EXTRA_NETWORK_INFO);
    if (ConnectivityManager.TYPE_WIFI == netInfo.getType ()) {
        String ssid = info.getExtraInfo()
        Log.d(TAG, "WiFi SSID: " + ssid)
    }
}

If you are not using BroadcastReceiver check this answer to get SSID using Context

There are 3 steps:

1. Find which files cause conflicts by command

   git status
   

2. Check the files, in which you would find the conflicts marked like

   <<<<<<<<head
   blablabla
   

3. Change it to the way you want it, then commit with commands

   git add solved_conflicts_files
   git commit -m 'merge msg'
   

Adding export PATH="/Users/<username>/anaconda/bin:$PATH" (or export PATH="/Users/<username>/anaconda3/bin:$PATH" if you have anaconda 3) to my ~/.bash_profile file, fixed this issue for me.

You can use google's chart api to generate charts.

The Following:

.show-grid [class*="span"] {

means that all child elements of '.show-grid' with a class that CONTAINS the word 'span' in it will acquire those CSS properties.

<div class="show-grid">
  <div class="span">.span</div>
  <div class="span6">span6</div>
  <div class="attention-span">attention</div>
  <div class="spanish">spanish</div>
  <div class="mariospan">mariospan</div>
  <div class="espanol">espanol</div>

  <div>
    <div class="span">.span</div>
  </div>

  <p class="span">span</p>
  <span class="span">I do GET HIT</span>

  <span>I DO NOT GET HIT since I need a class of 'span'</span>
</div>

<div class="span">I DO NOT GET HIT since I'm outside of .show-grid</span>

All of the elements get hit except for the <span> by itself.

In Regards to Bootstrap:

• span6 : this was Bootstrap 2's scaffolding technique which divided a section into a horizontal grid, based on parts of 12. Thus span6 would have a width of 50%.
• In the current day implementation of Bootstrap (v.3 and v.4), you now use the .col-* classes (e.g. col-sm-6), which also specifies a media breakpoint to handle responsiveness when the window shrinks below a certain size. Check Bootstrap 4.1 and Bootstrap 3.3.7 for more documentation. I would recommend going with a later Bootstrap nowadays

$where = "name='Joe' AND status='boss' OR status='active'";

$this->db->where($where);

Try:

start  "" "C:\Program Files (x86)\Microsoft Office\Office12\WINWORD.EXE" --new-window/min

I had the same problem, but I was trying to open chrome.exe maximized. If I put the /min anywhere else in the command line, like before or after the empty title, it was ignored.

For completeness, if "AllowOverride All" doesn't fix your problem, you could debug this problem using:

1. Run apachectl -S and see if you have more than one namevhost. It might be that httpd is looking for .htaccess of another DocumentRoot.

2. Use strace -f apachectl -X and look for where it's loading (or not loading) .htaccess from.

Key in 1 + G and it will take you to the beginning of the file. Converserly, G will take you to the end of the file.

You can do it in one line as following. Hope you are in git repository which need the cherry-picked change and you have checked out to correct branch.

git fetch ssh://[email protected]:7999/repo_to_get_it_from.git branchToPickFrom && git cherry-pick 02a197e9533
# 

git fetch [branch URL] [Branch to cherry-pick from] && git cherry-pick [commit ID]

another way is to use certutil.exe save your username and password in a file e.g. in.txt as username:password

certutil -encode in.txt out.txt

Now you should be able to use auth value from out.txt

$headers = @{ Authorization = "Basic $((get-content out.txt)[1])" }
Invoke-WebRequest -Uri 'https://whatever' -Headers $Headers

The core problem seems to be you are opening a window to show a page whose content is already cached in the browser. Therefore no loading happens and therefore no load-event happens.

One possibility could be to use the 'pageshow' -event instead, as described in:

https://support.microsoft.com/en-us/help/3011939/onload-event-does-not-occur-when-clicking-the-back-button-to-a-previou

The answer I got is that variables and subqueries will not work and we have to user dynamic SQL script. The following works:

DECLARE @SQL VARCHAR(4000)
SET @SQL = 'ALTER TABLE dbo.Student DROP CONSTRAINT |ConstraintName| '

SET @SQL = REPLACE(@SQL, '|ConstraintName|', ( SELECT   name
                                               FROM     sysobjects
                                               WHERE    xtype = 'PK'
                                                        AND parent_obj =        OBJECT_ID('Student')))

EXEC (@SQL)

in my case I had to use both symbolic IP address "0.0.0.0" and call back while listen to server "cors": "^2.8.5", "express": "^4.17.1",

const cors = require("cors");
app.use(cors());

const port = process.env.PORT || 8000;
app.listen(port,"0.0.0.0" ,() => {
  console.log(`Server is running on port ${port}`);
});

you can also use, your local IP address instead of "0.0.0.0", In OS Ubuntu you can find your Ip address by using command

ifconfig | grep "inet " | grep -v 127.0.0.1

Then use the Ip Address:

app.listen(port,"192.168.0.131" ,() => {
  console.log(`Server is running on port ${port}`);
});

If you use fixed Ip address such as "192.168.0.131", then you must use it while calling to the server, such as, My api calling configuration for react client is bellow:

REACT_APP_API_URL = http://192.168.0.131:8001/api

You can add references to your model through command line in the following manner:

rails g migration add_column_to_tester user_id:integer

This will generate a migration file like :

class AddColumnToTesters < ActiveRecord::Migration
  def change
    add_column :testers, :user_id, :integer
  end
end

This works fine every time i use it..

This will also work if the pattern you want to match is a variable.

dbh = new DbHelper(this);
SQLiteDatabase db = dbh.getWritableDatabase();

Cursor c = db.query(
    "TableName", 
    new String[]{"ColumnName"}, 
    "ColumnName LIKE ?", 
    new String[]{_data+"%"}, 
    null, 
    null, 
    null
);

while(c.moveToNext()){
    // your calculation goes here
}

I had used the WebDeploy IIS Extension to import my websites from IIS6 to IIS7.5, so all of the IIS settings were exactly as they had been in the production environment. After trying all the solutions provided here, none of which worked for me, I simply had to change the App Pool setting for the website from Classic to Integrated.

From the MySQL 5.5 documentation:

One TIMESTAMP column in a table can have the current timestamp as the default value for initializing the column, as the auto-update value, or both. It is not possible to have the current timestamp be the default value for one column and the auto-update value for another column.

Changes in MySQL 5.6.5:

Previously, at most one TIMESTAMP column per table could be automatically initialized or updated to the current date and time. This restriction has been lifted. Any TIMESTAMP column definition can have any combination of DEFAULT CURRENT_TIMESTAMP and ON UPDATE CURRENT_TIMESTAMP clauses. In addition, these clauses now can be used with DATETIME column definitions. For more information, see Automatic Initialization and Updating for TIMESTAMP and DATETIME.

Good news for developers who is working with latest version of visual studio

The Web Essentials are coming with this feature .

I came across this question when trying to check if a file existed on an FTP site or not. If the file doesn't exist there will be an error when trying to check its timestamp. But I want to make sure the error is not something else, by checking its type.

The Response property on WebException will be of type FtpWebResponse on which you can check its StatusCode property to see which FTP error you have.

Here's the code I ended up with:

    public static bool FileExists(string host, string username, string password, string filename)
    {
        // create FTP request
        FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://" + host + "/" + filename);
        request.Credentials = new NetworkCredential(username, password);

        // we want to get date stamp - to see if the file exists
        request.Method = WebRequestMethods.Ftp.GetDateTimestamp;

        try
        {
            FtpWebResponse response = (FtpWebResponse)request.GetResponse();
            var lastModified = response.LastModified;

            // if we get the last modified date then the file exists
            return true;
        }
        catch (WebException ex)
        {
            var ftpResponse = (FtpWebResponse)ex.Response;

            // if the status code is 'file unavailable' then the file doesn't exist
            // may be different depending upon FTP server software
            if (ftpResponse.StatusCode == FtpStatusCode.ActionNotTakenFileUnavailable)
            {
                return false;
            }

            // some other error - like maybe internet is down
            throw;
        }
    }

You don't need to do special things in the form. You just build the comment correctly in the show action:

class ArticlesController < ActionController::Base
  ....
  def show
    @article = Article.find(params[:id])
    @new_comment = @article.comments.build
  end
  ....
end

and then make a form for it in the article view:

<% form_for @new_comment do |f| %>
   <%= f.text_area :text %>
   <%= f.submit "Post Comment" %>
<% end %>

by default, this comment will go to the create action of CommentsController, which you will then probably want to put redirect :back into so you're routed back to the Article page.

I had this problem when I installed MySQL 8.0.15 with the community installer. The my.ini file that came with the installer did not work correctly after it had been edited. I did a full manual install by downloading that zip folder. I was able to create my own my.ini file containing only the parameters that I was concerned about and it worked.

1. download zip file from MySQL website
2. unpack the folder into C:\program files\MySQL\MySQL8.0
3. within the MySQL8.0 folder that you unpacked the zip folder into, create a text file and save it as my.ini

4. include the parameters in that my.ini file that you are concerned about. so something like this(just ensure that there is already a folder created for the datadir or else initialization won't work):

   [mysqld]
   basedire=C:\program files\MySQL\MySQL8.0
   datadir=D:\MySQL\Data
   ....continue with whatever parameters you want to include
   

5. initialize the data directory by running these two commands in the command prompt:

   cd C:\program files\MySQL\MySQL8.0\bin
   mysqld --default-file=C:\program files\MySQL\MySQL8.0\my.ini --initialize
   

6. install the MySQL server as a service by running these two commands:

   cd C:\program files\MySQL\MySQL8.0\bin
   mysqld --install --default-file=C:\program files\MySQL\MySQL8.0\my.ini
   

7. finally, start the server for the first time by running these two commands:

   cd C:\program files\MySQL\MySQL8.0\bin
   mysqld --console
   

Look at the r.status_code attribute:

if r.status_code == 404:
    # A 404 was issued.

Demo:

>>> import requests
>>> r = requests.get('http://httpbin.org/status/404')
>>> r.status_code
404

If you want requests to raise an exception for error codes (4xx or 5xx), call r.raise_for_status():

>>> r = requests.get('http://httpbin.org/status/404')
>>> r.raise_for_status()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "requests/models.py", line 664, in raise_for_status
    raise http_error
requests.exceptions.HTTPError: 404 Client Error: NOT FOUND
>>> r = requests.get('http://httpbin.org/status/200')
>>> r.raise_for_status()
>>> # no exception raised.

You can also test the response object in a boolean context; if the status code is not an error code (4xx or 5xx), it is considered ‘true’:

if r:
    # successful response

If you want to be more explicit, use if r.ok:.

You can just go with:

if(!$strings{$string}) ....

This example works. Try it.

var array = [0,1,2];
for( var i = 0, ii = array.length; i < ii; i++){
  if(i === 1){
   break;
  }
}

As of API 24, sending a file:// URI to another app will throw a FileUriExposedException. Instead, use FileProvider to send a content:// URI:

public File getFile(Context context, String fileName) {
    if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
        return null;
    }

    File storageDir = context.getExternalFilesDir(null);
    return new File(storageDir, fileName);
}

public Uri getFileUri(Context context, String fileName) {
    File file = getFile(context, fileName);
    return FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", file);
}

You must also define the FileProvider in your manifest:

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="com.mydomain.fileprovider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths" />
</provider>

Example file_paths.xml:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-files-path name="name" path="path" />
</paths>

Replace "name" and "path" as appropriate.

To give the PDF viewer access to the file, you also have to add the FLAG_GRANT_READ_URI_PERMISSION flag to the intent:

private void displayPdf(String fileName) {
    Uri uri = getFileUri(this, fileName);

    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(uri, "application/pdf");

    // FLAG_GRANT_READ_URI_PERMISSION is needed on API 24+ so the activity opening the file can read it
    intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_GRANT_READ_URI_PERMISSION);

    if (intent.resolveActivity(getPackageManager()) == null) {
        // Show an error
    } else {
        startActivity(intent);
    }
}

See the FileProvider documentation for more details.

Also, there is a DOS comnand "tree". You can displays directory paths and files in each subdirectory with command:

After merging if you are unable to push commit, Use the push command with -f

git push -f origin branch-name

Where origin is the name of your remote repo.

I found it easier to edit the project file directly e.g. YourApp.csproj.

You can do this by modifying ApplicationIcon property element:

<ApplicationIcon>..\Path\To\Application.ico</ApplicationIcon>

Also, if you create an MSI installer for your application e.g. using WiX, you can use the same icon again for display in Add/Remove Programs. See tip 5 here.

PostgreSQL supports boolean types, so your SQL query would work perfectly in PostgreSQL.

Activity

To pass a bitmap between Activites

Intent intent = new Intent(this, Activity.class);
intent.putExtra("bitmap", bitmap);

And in the Activity class

Bitmap bitmap = getIntent().getParcelableExtra("bitmap");

Fragment

To pass a bitmap between Fragments

SecondFragment fragment = new SecondFragment();
Bundle bundle = new Bundle();
bundle.putParcelable("bitmap", bitmap);
fragment.setArguments(bundle);

To receive inside the SecondFragment

Bitmap bitmap = getArguments().getParcelable("bitmap");

Transferring large bitmap (Compress bitmap)

If you are getting failed binder transaction, this means you are exceeding the binder transaction buffer by transferring large element from one activity to another activity.

So in that case you have to compress the bitmap as an byte's array and then uncompress it in another activity, like this

In the FirstActivity

Intent intent = new Intent(this, SecondActivity.class);

ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPG, 100, stream);
byte[] bytes = stream.toByteArray(); 
intent.putExtra("bitmapbytes",bytes);

And in the SecondActivity

byte[] bytes = getIntent().getByteArrayExtra("bitmapbytes");
Bitmap bmp = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);

split_part() does what you want in one step:

SELECT split_part(col, ',', 1) AS col1
     , split_part(col, ',', 2) AS col2
     , split_part(col, ',', 3) AS col3
     , split_part(col, ',', 4) AS col4
FROM   tbl;

Add as many lines as you have items in col (the possible maximum). Columns exceeding data items will be empty strings ('').

I would like to expand on Martin's answer there...

His solution is rather nice, but it can be tweaked so any "variable type" can be printed like that.(It's actually Value Type, more on the topic). That said, "tweaked" may be a strong word for this. Regardless, it may be helpful.

Martins Solution:

a.getClass().getName()

However, If you want it to work with anything you can do this:

((Object) myVar).getClass().getName()
//OR
((Object) myInt).getClass().getSimpleName()

In this case, the primitive will simply be wrapped in a Wrapper. You will get the Object of the primitive in that case.

I myself used it like this:

private static String nameOf(Object o) {
    return o.getClass().getSimpleName();
}

Using Generics:

public static <T> String nameOf(T o) {
    return o.getClass().getSimpleName();
}

Because abstract classes have state (fields) and somethimes they need to be initialized somehow.

It allows you to queue up animations... for example, instead of this

$('#my-element').animate( { opacity: 0.2, width: '100px' }, 2000);

Which fades the element and makes the width 100 px at the same time. Using the queue allows you to stage the animations. So one finishes after the other.

$("#show").click(function () {
    var n = $("div").queue("fx");
    $("span").text("Queue length is: " + n.length);
});

function runIt() {
    $("div").show("slow");
    $("div").animate({left:'+=200'},2000);
    $("div").slideToggle(1000);
    $("div").slideToggle("fast");
    $("div").animate({left:'-=200'},1500);
    $("div").hide("slow");
    $("div").show(1200);
    $("div").slideUp("normal", runIt);
}
runIt();

Example from http://docs.jquery.com/Effects/queue

As offer_date is an number, and is of lower accuracy than your real dates, this may work...
- Convert your real date to a string of format YYYYMM
- Conver that value to an INT
- Compare the result you your offer_date

SELECT
  *
FROM
  offers
WHERE
    offer_date = (SELECT CAST(to_char(create_date, 'YYYYMM') AS INT) FROM customers where id = '12345678')
AND offer_rate > 0 

Also, by doing all the manipulation on the create_date you only do the processing on one value.

Additionally, had you manipulated the offer_date you would not be able to utilise any index on that field, and so force SCANs instead of SEEKs.

CONVERT is SQL Server specific, CAST is ANSI.

CONVERT is more flexible in that you can format dates etc. Other than that, they are pretty much the same. If you don't care about the extended features, use CAST.

EDIT:

As noted by @beruic and @C-F in the comments below, there is possible loss of precision when an implicit conversion is used (that is one where you use neither CAST nor CONVERT). For further information, see CAST and CONVERT and in particular this graphic: SQL Server Data Type Conversion Chart. With this extra information, the original advice still remains the same. Use CAST where possible.

Solution:

var answerInt = [];
var answerString = "1,2,3,4";
answerString.split(',').forEach(function (item) {
   answerInt.push(parseInt(item))
});

You can grow them row by row by appending or using rbind().

That does not mean you should. Dynamically growing structures is one of the least efficient ways to code in R.

If you can, allocate your entire data.frame up front:

N <- 1e4  # total number of rows to preallocate--possibly an overestimate

DF <- data.frame(num=rep(NA, N), txt=rep("", N),  # as many cols as you need
                 stringsAsFactors=FALSE)          # you don't know levels yet

and then during your operations insert row at a time

DF[i, ] <- list(1.4, "foo")

That should work for arbitrary data.frame and be much more efficient. If you overshot N you can always shrink empty rows out at the end.

create a libs folder in the inside WEB-INF directory and add jstl, standard jars as below.

Or if you like to mix outputs (stdout & stderr) in one single file you may want to use:

command > merged-output.txt 2>&1

Scenario: Removing NodeJS when Windows has no Program Entry for your Node installation

I ran into a problem where my version of NodeJS (0.10.26) could NOT be uninstalled nor removed, because Programs & Features in Windows 7 (aka Add/Remove Programs) had no record of my having installed NodeJS... so there was no option to remove it short of manually deleting registry keys and files.

Command to verify your NodeJS version: node --version

I attempted to install the newest recommended version of NodeJS, but it failed at the end of the installation process and rolled back. Multiple versions of NodeJS also failed, and the installer likewise rolled them back as well. I could not upgrade NodeJS from the command line as I did not have SUDO installed.

SOLUTION: After spending several hours troubleshooting the problem, including upgrading NPM, I decided to reinstall the EXACT version of NodeJS on my system, over the top of the existing installation.

That solution worked, and it reinstalled NodeJS without any errors. Better yet, it also added an official entry in Add/Remove Programs dialogue.

Now that Windows was aware of the forgotten NodeJS installation, I was able to uninstall my existing version of NodeJS completely. I then successfully installed the newest recommended release of NodeJS for the Windows platform (version 4.4.5 as of this writing) without a roll-back initiating.

It took me a while to reach sucess, so I am posting this in case it helps anyone else with a similar issue.

you can use flex box for it.. this will solve your problem

.image-parent 
{
     height:33px; 
     display:flex; 
}

As an addendum, if you want to reapply your changes on top of the remote, you can also try:

git pull --rebase origin master

If you then want to undo some of your changes (but perhaps not all of them) you can use:

git reset SHA_HASH

Then do some adjustment and recommit.

This can be used in to solve this problem

<div id='scrol'></div> 

in javascript use this

jQuery("div#scrol").scrollTop(jQuery("div#scrol")[0].scrollHeight);

Use console.log(JSON.stringify(result)) to get the JSON in a string format.

EDIT: If your intention is to get the id and other properties from the result object and you want to see it console to know if its there then you can check with hasOwnProperty and access the property if it does exist:

var obj = {id : "007", name : "James Bond"};
console.log(obj);                    // Object { id: "007", name: "James Bond" }
console.log(JSON.stringify(obj));    //{"id":"007","name":"James Bond"}
if (obj.hasOwnProperty("id")){
    console.log(obj.id);             //007
}

Here's a function that'll do it:

def totuple(a):
    try:
        return tuple(totuple(i) for i in a)
    except TypeError:
        return a

And an example:

>>> array = numpy.array(((2,2),(2,-2)))
>>> totuple(array)
((2, 2), (2, -2))

var firstNumber=5000,
secondeNumber=37;

var decimalResult = decimal.Divide(firstNumber,secondeNumber);

Console.WriteLine(decimalResult );

The answer above covers everything in great detail, apart from a couple of things.

First, if there are no styles, then the (Context context, AttributeSet attrs) method signature will be used to instantiate the preference. In this case just use context.obtainStyledAttributes(attrs, R.styleable.MyCustomView) to get the TypedArray.

Secondly it does not cover how to deal with plaurals resources (quantity strings). These cannot be dealt with using TypedArray. Here is a code snippet from my SeekBarPreference that sets the summary of the preference formatting its value according to the value of the preference. If the xml for the preference sets android:summary to a text string or a string resouce the value of the preference is formatted into the string (it should have %d in it, to pick up the value). If android:summary is set to a plaurals resource, then that is used to format the result.

// Use your own name space if not using an android resource.
final static private String ANDROID_NS = 
    "http://schemas.android.com/apk/res/android";
private int pluralResource;
private Resources resources;
private String summary;

public SeekBarPreference(Context context, AttributeSet attrs) {
    // ...
    TypedArray attributes = context.obtainStyledAttributes(
        attrs, R.styleable.SeekBarPreference);
    pluralResource =  attrs.getAttributeResourceValue(ANDROID_NS, "summary", 0);
    if (pluralResource !=  0) {
        if (! resources.getResourceTypeName(pluralResource).equals("plurals")) {
            pluralResource = 0;
        }
    }
    if (pluralResource ==  0) {
        summary = attributes.getString(
            R.styleable.SeekBarPreference_android_summary);
    }
    attributes.recycle();
}

@Override
public CharSequence getSummary() {
    int value = getPersistedInt(defaultValue);
    if (pluralResource != 0) {
        return resources.getQuantityString(pluralResource, value, value);
    }
    return (summary == null) ? null : String.format(summary, value);
}

• This is just given as an example, however, if you want are tempted to set the summary on the preference screen, then you need to call notifyChanged() in the preference's onDialogClosed method.

You can use this method:

boolean isAlive()

It returns true if the thread is still alive and false if the Thread is dead. This is not static. You need a reference to the object of the Thread class.

One more tip: If you're checking it's status to make the main thread wait while the new thread is still running, you may use join() method. It is more handy.

Few note worthy differences between List and Set in Java are given as following :

1) Fundamental difference between List and Set in Java is allowing duplicate elements. List in Java allows duplicates while Set doesn't allow any duplicate. If you insert duplicate in Set it will replace the older value. Any implementation of Set in Java will only contains unique elements.

2) Another significant difference between List and Set in Java is order. List is an Ordered Collection while Set is an unordered Collection. List maintains insertion order of elements, means any element which is inserted before will go on lower index than any element which is inserted after. Set in Java doesn't maintain any order. Though Set provide another alternative called SortedSet which can store Set elements in specific Sorting order defined by Comparable and Comparator methods of Objects stored in Set.

3) Popular implementation of List interface in Java includes ArrayList, Vector and LinkedList. While popular implementation of Set interface includes HashSet, TreeSet and LinkedHashSet.

Its pretty clear that if you need to maintain insertion order or object and you collection can contain duplicates than List is a way to go. On the other hand if your requirement is to maintain unique collection without any duplicates than Set is the way to go.

According to this official guide, you can add WindowManager.LayoutParams.FLAG_SECURE to your window layout and it will disallow screenshots.

Use assertNotNull(obj). assert means must be.

Try this:

SELECT
   PropertyId,
   SUM(Amount) as TOTAL_COSTS
FROM
   MyTable
WHERE
   EndDate IS NULL
GROUP BY
   PropertyId

There are a few ways to handle rendering/showing controls on the page and you should take note to what happens with each method.

Rendering and Visibility

There are some instances where elements on your page don't need to be rendered for the user because of some type of logic or database value. In this case, you can prevent rendering (creating the control on the returned web page) altogether. You would want to do this if the control doesn't need to be shown later on the client side because no matter what, the user viewing the page never needs to see it.

Any controls or elements can have their visibility set from the server side. If it is a plain old html element, you just need to set the runat attribute value to server on the markup page.

<div id="myDiv" runat="server"></div>

The decision to render the div or not can now be done in the code behind class like so:

myDiv.Visible = someConditionalBool;

If set to true, it will be rendered on the page and if it's false it won't be rendered at all, not even hidden.

Client Side Hiding

Hiding an element is done on the client side only. Meaning, it's rendered but it has a display CSS style set on it which instructs your browser to not show it to the user. This is beneficial when you want to hide/show things based on user input. It's important to know that the element CAN be hidden on the server side too as long as the element/control has runat=server set just as I explained in the previous example.

Hiding in the Code Behind Class

To hide an element that you want rendered to the page but hidden is another simple single line of code:

myDiv.Style["display"] = "none";

If you have a need to remove the display style server side, it can be done by removing the display style, or setting it to a different value like inline or block (values described here).

myDiv.Style.Remove("display");
// -- or --
myDiv.Style["display"] = "inline";

Hiding on the Client Side with javascript

Using plain old javascript, you can easily hide the same element in this manner

var myDivElem = document.getElementById("myDiv");
myDivElem.style.display = "none";

// then to show again
myDivElem.style.display = "";

jQuery makes hiding elements a little simpler if you prefer to use jQuery:

var myDiv = $("#<%=myDiv.ClientID%>");
myDiv.hide();

// ... and to show 
myDiv.show();

IMPORTANT NOTE

I am posting this as an answer, not a comment, as it is rather important info and it will attract more attention in this format.

As other fellows pointed, you can force a device to show you a numeric keyboard with type="number" / type="tel", but I must emphasize that you have to be extremely cautious with this.

If someone expects a number beginning with zeros, such as 000222, then she is likely to have trouble, as some browsers (desktop Chrome, for instance) will send to the server 222, which is not what she wants.

About type="tel" I can't say anything similar but personally I do not use it, as its behavior on different telephones can vary. I have confined myself to the simple pattern="[0-9]*" which do not work in Android

const chunkStr = (str, n, acc) => {     
    if (str.length === 0) {
        return acc
    } else {
        acc.push(str.substring(0, n));
        return chunkStr(str.substring(n), n, acc);
    }
}
const str = 'abcdefghijkl';
const splittedString = chunkStr(str, 3, []);

What is blob url? Why it is used?

BLOB is just byte sequence. Browser recognize it as byte stream. It is used to get byte stream from source.

A Blob object represents a file-like object of immutable, raw data. Blobs represent data that isn't necessarily in a JavaScript-native format. The File interface is based on Blob, inheriting blob functionality and expanding it to support files on the user's system.

Can i make my own blob url on a server?

Yes you can there are serveral ways to do so for example try http://php.net/manual/en/function.ibase-blob-echo.php

Tips from 2020:

From Flask 1.0, it defaults to enable multiple threads (source), you don't need to do anything, just upgrade it with:

$ pip install -U flask

If you are using flask run instead of app.run() with older versions, you can control the threaded behavior with a command option (--with-threads/--without-threads):

$ flask run --with-threads

It's same as app.run(threaded=True)

If a TCP packet is lost, it will be resent. That is not handy for applications that rely on data being handled in a specific order in real time.

Examples include video streaming and especially VoIP (e.g. Skype). In those instances, however, a dropped packet is not such a big deal: our senses aren't perfect, so we may not even notice. That is why these types of applications use UDP instead of TCP.

I made a port of the excellent xcolor library to remove its jQuery dependency. There are a ton of functions in there including lightening and darkening colors.

Really, converting hex to RGB is a completely separate function from lightening or darkening colors. Keep things DRY please. In any case, once you have an RGB color, you can just add the difference between the light level you want and the light level you have to each of the RGB values:

var lightness = function(level) {
    if(level === undefined) {
        return Math.max(this.g,this.r,this.b)
    } else {
        var roundedLevel = Math.round(level) // fractions won't work here
        var levelChange = roundedLevel - this.lightness()

        var r = Math.max(0,this.r+levelChange)
        var g = Math.max(0,this.g+levelChange)
        var b = Math.max(0,this.b+levelChange)

        if(r > 0xff) r = 0xff
        if(g > 0xff) g = 0xff
        if(b > 0xff) b = 0xff

        return xolor({r: r, g: g, b: b})
    }
}

var lighter = function(amount) {
    return this.lightness(this.lightness()+amount)
}

See https://github.com/fresheneesz/xolor for more of the source.

The pytz module is one option, and there is another python-dateutil, which although is also third party package, may already be available depending on your other dependencies and operating system.

I just wanted to include this methodology for reference- if you've already installed python-dateutil for other purposes, you can use its tzinfo instead of duplicating with pytz

import datetime
import dateutil.tz

# Get the UTC time with datetime.now:
utcdt = datetime.datetime.now(dateutil.tz.tzutc())

# Get the UTC time with datetime.utcnow:
utcdt = datetime.datetime.utcnow()
utcdt = utcdt.replace(tzinfo=dateutil.tz.tzutc())

# For fun- get the local time
localdt = datetime.datetime.now(dateutil.tz.tzlocal())

I tend to agree that calls to utcnow should include the UTC timezone information. I suspect that this is not included because the native datetime library defaults to naive datetimes for cross compatibility.

Since the FragmentManager will take care of restoring your Fragments for you as soon as the onResume() method is called I have the fragment call out to the activity and add itself to a list. In my instance I am storing all of this in my PagerAdapter implementation. Each fragment knows it's position because it is added to the fragment arguments on creation. Now whenever I need to manipulate a fragment at a specific index all I have to do is use the list from my adapter.

The following is an example of an Adapter for a custom ViewPager that will grow the fragment as it moves into focus, and scale it down as it moves out of focus. Besides the Adapter and Fragment classes I have here all you need is for the parent activity to be able to reference the adapter variable and you are set.

You can join your array using the following:

string.Join(",", Client);

Then you can output anyway you want. You can change the comma to what ever you want, a space, a pipe, or whatever.
