The lookup module of ansible works fine for me. The yml is:

- hosts: test
  vars:
    time: "{{ lookup('pipe', 'date -d \"1 day ago\" +\"%Y%m%d\"') }}"

You can replace any command with date to get result of the command.

This should fix it:

var total = 0;   
$(".price").each( function(){
          total += $(this).val() * 1;
});

Are you looking for the syntax to open them:

Dim wkbk As Workbook

Set wkbk = Workbooks.Open("C:\MyDirectory\mysheet.xlsx")

Then, you can use wkbk.Sheets(1).Range("3:3") (or whatever you need)

Hadley has been developing a package called forcats. This package makes the task so much easier. You can exploit fct_infreq() when you want to change the order of x-axis by the frequency of a factor. In the case of the mtcars example in this post, you want to reorder levels of cyl by the frequency of each level. The level which appears most frequently stays on the left side. All you need is the fct_infreq().

library(ggplot2)
library(forcats)

ggplot(mtcars, aes(fct_infreq(factor(cyl)))) +
geom_bar() +
labs(x = "cyl")

If you wanna go the other way around, you can use fct_rev() along with fct_infreq().

ggplot(mtcars, aes(fct_rev(fct_infreq(factor(cyl))))) +
geom_bar() +
labs(x = "cyl") 

there are lots of compression methods that work recursively command line and its good to know who the end audience is.

i.e. if it is to be sent to someone running windows then zip would probably be best:

zip -r file.zip folder_to_zip

unzip filenname.zip

for other linux users or your self tar is great

tar -cvzf filename.tar.gz folder

tar -cvjf filename.tar.bz2 folder  # even more compression

#change the -c to -x to above to extract

One must be careful with tar and how things are tarred up/extracted, for example if I run

cd ~
tar -cvzf passwd.tar.gz /etc/passwd
tar: Removing leading `/' from member names
/etc/passwd


pwd

/home/myusername

tar -xvzf passwd.tar.gz

this will create /home/myusername/etc/passwd

unsure if all versions of tar do this:

 Removing leading `/' from member names

If you bind to a (collection) of concrete objects, you can get the that concrete object via the DataBoundItem property of the row. (To avoid check for magic strings in the cell and using "real" properties of the object)

Skeleton example below:

DTO/POCO

public class Employee
{
    public int EmployeeKey {get;set;}

    public string LastName {get;set;}

    public string FirstName {get;set;}

    public bool IsActive {get;set;}
}       

Binding to the datagridview

    private void BindData(ICollection<Employee> emps)
    {
        System.ComponentModel.BindingList<Employee> bindList = new System.ComponentModel.BindingList<Employee>(emps.OrderBy(emp => emp.LastName).ThenBy(emp => emp.FirstName).ToList());
        this.dgvMyDataGridView.DataSource = bindList;
    }       

then the event handler and getting the concrete object (instead of a DataGridRow and/or cells)

        private void dgvMyDataGridView_RowPrePaint(object sender, DataGridViewRowPrePaintEventArgs e)
        {
            Employee concreteSelectedRowItem = this.dgvMyDataGridView.Rows[e.RowIndex].DataBoundItem as Employee;
            if (null != concreteSelectedRowItem && !concreteSelectedRowItem.IsActive)
            {
                dgvMyDataGridView.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.LightGray;
            }
        }

Here's what worked for me to trigger a rebuild on a PR that Dependabot had opened, but failed due to errors in .travis.yml:

1. Close the PR
2. Wait for Dependabot to comment ("OK, I won't notify you again about this release, but will get in touch when a new version is available."). It will remove its branch.
3. Restore the branch Dependabot removed (something like dependabot/cargo/tempfile-3.0.4).
4. Open the PR again

Below are steps to update cocoapods :

1. Open terminal (Shortcut : Press cmd + space tab to open Spotlight then text in terminal)
2. Use command sudo gem install cocoapods. This will ask for system password due to security concern thereafter it installs gems

3. Now, set up pod using pod setup command. This will setup cocoapods master repo.

4. You can check the version of cocoapods using pod --version command.

Try this:

//the code will execute in 1 3 5 7 9 seconds later
function exec() {
    for(var i=0;i<5;i++) {
        setTimeout(function() {
            console.log(new Date());   //It's you code
        },(i+i+1)*1000);
    }
}

I believe app:itemBackground expects a drawable. So follow the steps below :

Make a drawable file highlight_color.xml with following contents :

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
     <solid android:color="YOUR HIGHLIGHT COLOR"/>
</shape>

Make another drawable file nav_item_drawable.xml with following contents:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:drawable="@drawable/highlight_color" android:state_checked="true"/>
</selector>

Finally add app:itemBackground tag in the NavView :

<android.support.design.widget.NavigationView
android:id="@+id/activity_main_navigationview"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/drawer_header"
app:itemIconTint="@color/black"
app:itemTextColor="@color/primary_text"
app:itemBackground="@drawable/nav_item_drawable"
app:menu="@menu/menu_drawer">

here the highlight_color.xml file defines a solid color drawable for the background. Later this color drawable is assigned to nav_item_drawable.xml selector.

This worked for me. Hopefully this will help.

********************************************** UPDATED **********************************************

Though the above mentioned answer gives you fine control over some properties, but the way I am about to describe feels more SOLID and is a bit COOLER.

So what you can do is, you can define a ThemeOverlay in the styles.xml for the NavigationView like this :

    <style name="ThemeOverlay.AppCompat.navTheme">

        <!-- Color of text and icon when SELECTED -->
        <item name="colorPrimary">@color/color_of_your_choice</item> 

        <!-- Background color when SELECTED -->
        <item name="colorControlHighlight">@color/color_of_your_choice</item> 

    </style>

now apply this ThemeOverlay to app:theme attribute of NavigationView, like this:

<android.support.design.widget.NavigationView
android:id="@+id/activity_main_navigationview"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:theme="@style/ThemeOverlay.AppCompat.navTheme"
app:headerLayout="@layout/drawer_header"
app:menu="@menu/menu_drawer">

I hope this will help.

Pandas uses matplotlib as a library for basic plots. The easiest way in your case will using the following:

import pandas as pd
import numpy as np

#creating sample data 
sample_data={'col_name_1':np.random.rand(20),
      'col_name_2': np.random.rand(20)}
df= pd.DataFrame(sample_data)
df.plot(x='col_name_1', y='col_name_2', style='o')

However, I would recommend to use seaborn as an alternative solution if you want have more customized plots while not going into the basic level of matplotlib. In this case you the solution will be following:

import pandas as pd
import seaborn as sns
import numpy as np

#creating sample data 
sample_data={'col_name_1':np.random.rand(20),
      'col_name_2': np.random.rand(20)}
df= pd.DataFrame(sample_data)
sns.scatterplot(x="col_name_1", y="col_name_2", data=df)

    <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:template match="/">
        <newBooks>
                <xsl:for-each select="books/book">
                        <newBook>
                                <countNo><xsl:value-of select="position()"/></countNo>
                                <title>
                                        <xsl:value-of select="title"/>
                                </title>
                        </newBook>
                </xsl:for-each>
        </newBooks>
    </xsl:template>
</xsl:stylesheet>

Why don't you just save/serve the CSS file as UTF-8?

nav a:hover:after {
    content: "?";
}

If that's not good enough, and you want to keep it all-ASCII:

nav a:hover:after {
    content: "\2193";
}

The general format for a Unicode character inside a string is \000000 to \FFFFFF – a backslash followed by six hexadecimal digits. You can leave out leading 0 digits when the Unicode character is the last character in the string or when you add a space after the Unicode character. See the spec below for full details.

Relevant part of the CSS2 spec:

Third, backslash escapes allow authors to refer to characters they cannot easily put in a document. In this case, the backslash is followed by at most six hexadecimal digits (0..9A..F), which stand for the ISO 10646 ([ISO10646]) character with that number, which must not be zero. (It is undefined in CSS 2.1 what happens if a style sheet does contain a character with Unicode codepoint zero.) If a character in the range [0-9a-fA-F] follows the hexadecimal number, the end of the number needs to be made clear. There are two ways to do that:

1. with a space (or other white space character): "\26 B" ("&B"). In this case, user agents should treat a "CR/LF" pair (U+000D/U+000A) as a single white space character.
2. by providing exactly 6 hexadecimal digits: "\000026B" ("&B")

In fact, these two methods may be combined. Only one white space character is ignored after a hexadecimal escape. Note that this means that a "real" space after the escape sequence must be doubled.

If the number is outside the range allowed by Unicode (e.g., "\110000" is above the maximum 10FFFF allowed in current Unicode), the UA may replace the escape with the "replacement character" (U+FFFD). If the character is to be displayed, the UA should show a visible symbol, such as a "missing character" glyph (cf. 15.2, point 5).

• Note: Backslash escapes are always considered to be part of an identifier or a string (i.e., "\7B" is not punctuation, even though "{" is, and "\32" is allowed at the start of a class name, even though "2" is not).
  The identifier "te\st" is exactly the same identifier as "test".

Comprehensive list: Unicode Character 'DOWNWARDS ARROW' (U+2193).

You need only to write:

Because this already makes the user a DB Administrator

There is a button Download ZIP. If you want to do a sparse checkout there are many solutions on the site. For example here.

this is a rehash of teoman shipahi's answer with a slightly less ambiguous name, and following the design priciple of defining code before you attempt to call it. (Whilst node allows you to do otherwise, it's not good a practice to put the cart before the horse.)

function rename_or_copy_and_delete (oldPath, newPath, callback) {

    function copy_and_delete () {
        var readStream = fs.createReadStream(oldPath);
        var writeStream = fs.createWriteStream(newPath);

        readStream.on('error', callback);
        writeStream.on('error', callback);
        readStream.on('close', 
              function () {
                fs.unlink(oldPath, callback);
              }
        );

        readStream.pipe(writeStream);
    }

    fs.rename(oldPath, newPath, 
        function (err) {
          if (err) {
              if (err.code === 'EXDEV') {
                  copy_and_delete();
              } else {
                  callback(err);
              }
              return;// << both cases (err/copy_and_delete)
          }
          callback();
        }
    );
}

The error you quote has nothing to do with pg_hba.conf; it's failing to connect, not failing to authorize the connection.

Do what the error message says:

Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections

You haven't shown the command that produces the error. Assuming you're connecting on localhost port 5432 (the defaults for a standard PostgreSQL install), then either:

• PostgreSQL isn't running

• PostgreSQL isn't listening for TCP/IP connections (listen_addresses in postgresql.conf)

• PostgreSQL is only listening on IPv4 (0.0.0.0 or 127.0.0.1) and you're connecting on IPv6 (::1) or vice versa. This seems to be an issue on some older Mac OS X versions that have weird IPv6 socket behaviour, and on some older Windows versions.

• PostgreSQL is listening on a different port to the one you're connecting on

• (unlikely) there's an iptables rule blocking loopback connections

(If you are not connecting on localhost, it may also be a network firewall that's blocking TCP/IP connections, but I'm guessing you're using the defaults since you didn't say).

So ... check those:

• ps -f -u postgres should list postgres processes

• sudo lsof -n -u postgres |grep LISTEN or sudo netstat -ltnp | grep postgres should show the TCP/IP addresses and ports PostgreSQL is listening on

BTW, I think you must be on an old version. On my 9.3 install, the error is rather more detailed:

$ psql -h localhost -p 12345
psql: could not connect to server: Connection refused
        Is the server running on host "localhost" (::1) and accepting
        TCP/IP connections on port 12345?

You have to be careful about the xib file. I tried all the above and nothing worked for me. I was using custom UIButtons defined in the xib, and realized it might be related to the fact that I had assigned attributes there which were not changing programmatically. If you've defined images or text there, remove them. When I did, my programmatic changes began to take effect.

I improved on Elad Katz' answer.

• Add LastItemMargin property to MarginSetter to specially handle the last item
• Add Spacing attached property with Vertical and Horizontal properties that adds spacing between items in vertical and horizontal lists and eliminates any trailing margin at the end of the list

Source code in gist.

Example:

<StackPanel Orientation="Horizontal" foo:Spacing.Horizontal="5">
  <Button>Button 1</Button>
  <Button>Button 2</Button>
</StackPanel>

<StackPanel Orientation="Vertical" foo:Spacing.Vertical="5">
  <Button>Button 1</Button>
  <Button>Button 2</Button>
</StackPanel>

<!-- Same as vertical example above -->
<StackPanel Orientation="Vertical" foo:MarginSetter.Margin="0 0 0 5" foo:MarginSetter.LastItemMargin="0">
  <Button>Button 1</Button>
  <Button>Button 2</Button>
</StackPanel>

Oracle does not have a simple database model like MySQL or MS SQL Server. I find the closest thing is to query the tablespaces and the corresponding users within them.

For example, I have a DEV_DB tablespace with all my actual 'databases' within them:

SQL> SELECT TABLESPACE_NAME FROM USER_TABLESPACES;

Resulting in:

SYSTEM
SYSAUX
UNDOTBS1
TEMP
USERS
EXAMPLE
DEV_DB

It is also possible to query the users in all tablespaces:

SQL> select USERNAME, DEFAULT_TABLESPACE from DBA_USERS;

Or within a specific tablespace (using my DEV_DB tablespace as an example):

SQL> select USERNAME, DEFAULT_TABLESPACE from DBA_USERS where DEFAULT_TABLESPACE = 'DEV_DB';

ROLES DEV_DB
DATAWARE DEV_DB
DATAMART DEV_DB
STAGING DEV_DB

You should be able to set the server.session.timeout in your application.properties file.

$cart = array();
$cart[] = 11;

//Above is correct. but below one is for further understanding

$cart = array();
for($i = 0; $i <= 5; $i++){
          $cart[] = $i;  

//if you write $cart = [$i]; you will only take last $i value as first element in array.

}
echo "<pre>";
print_r($cart);

NetBeans has a built-in profiler.

Intent intent = new Intent(getApplicationContext(), Splash_Screen.class);
                intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                intent.putExtra("EXIT", true);
                startActivity(intent);

put this in the oncreate and onResume of the very first activity that is opened. ex. is on splash screen activity

if (getIntent().getBooleanExtra("EXIT", false)) {
            this.finish();
            System.exit(0);
        }

In this case, the name of the selector is wrong. The colon here is part of the method signature; it means that the method takes one argument. I believe that you want

SEL sel = @selector(lowercaseString);

Here is tutorial how to do that (CATALINA_HOME is path to your Tomcat, so I suppose something like C:/Program Files/Tomcat/. And for starting server, you need to execute script startup.bat from command line, this will make it:)

I have had the same problem when I used easy-install to install pip for python 2.7.14. For me the solution was (might not be the best, but worked for me, and this is probably the simplest) that the folder that contained the easy-install.py also contained a folder pkg_resources, and i have copy-pasted this folder into the same folder where my pip-script.py script was (python27\Scripts). Since then, I found it in the python27\Lib\site-packages\pip-9.0.1-py2.7.egg\pip\_vendor folder as well, it might be a better solution to modify the pip-script.py file to import this.

In Eclipse, go to Help -> Install New Software -> Add -> Name: any name like egit; Location: http://download.eclipse.org/egit/updates -> Okay. Now Search for egit in Work with and select all the check boxes and press Next till finish.

File -> Import -> search Git and select "Projects from Git" -> Clone URI. In the URI, paste the HTTPS URL of the repository (the one with .git extension). -> Next ->It will show all the branches "Next" -> Local Destination "Next" -> "Import as a general project" -> Next till finish.

You can refer to this Youtube tutorial: https://www.youtube.com/watch?v=ptK9-CNms98

You can send Email by Jquery just follow these steps 

include this link : <script src="https://smtpjs.com/v3/smtp.js"></script>
after that use this code :

$( document ).ready(function() {
 Email.send({
Host : "smtp.yourisp.com",
Username : "username",
Password : "password",
To : '[email protected]',
From : "[email protected]",
Subject : "This is the subject",
Body : "And this is the body"}).then( message => alert(message));});

Try this:

 moment("02/26/1978", "MM/DD/YYYY").fromNow().split(" ")[0];

Explanation:

We receive string something like this: '23 days ago'. Split it to array: ['23', 'days', 'ago'] and then take first item '23'.

I've tried all the above, but nothing seems to work as expected. After a little research I found that e.relatedTarget is the html just before the mouse exits the window.

So ... I've end up with this:

document.body.addEventListener('mouseout', function(e) {
    if (e.relatedTarget === document.querySelector('html')) {
        console.log('We\'re OUT !');
    }
});

Please let me know if you find any issues or improvements !

2019 Update

(as user1084282 found out)

document.body.addEventListener('mouseout', function(e) {
    if (!e.relatedTarget && !e.toElement) {
        console.log('We\'re OUT !');
    }
});

Right click on you image to get resolution. In my case 1233 x 882

const { width } = Dimensions.get('window');

const ratio = 882 / 1233;

    const style = {
      width,
      height: width * ratio
    }

<Image source={image} style={style} resizeMode="contain" />

That all

I found the answer, thanks to your information Michelle. You can indeed get the right view using View#getChildAt(int index). The catch is that it starts counting from the first visible item. In fact, you can only get the visible items. You solve this with ListView#getFirstVisiblePosition().

Example:

private void updateView(int index){
    View v = yourListView.getChildAt(index - 
        yourListView.getFirstVisiblePosition());

    if(v == null)
       return;

    TextView someText = (TextView) v.findViewById(R.id.sometextview);
    someText.setText("Hi! I updated you manually!");
}

It's a table-valued function, but you're using it as a scalar function.

Try:

where Emp_Id IN (SELECT i.items FROM dbo.Splitfn(@Id,',') AS i)

But... also consider changing your function into an inline TVF, as it'll perform better.

The HttpClient methods allow you to set the params in it's options.

You can configure it by importing the HttpClientModule from the @angular/common/http package.

import {HttpClientModule} from '@angular/common/http';

@NgModule({
  imports: [ BrowserModule, HttpClientModule ],
  declarations: [ App ],
  bootstrap: [ App ]
})
export class AppModule {}

After that you can inject the HttpClient and use it to do the request.

import {HttpClient} from '@angular/common/http'

@Component({
  selector: 'my-app',
  template: `
    <div>
      <h2>Hello {{name}}</h2>
    </div>
  `,
})
export class App {
  name:string;
  constructor(private httpClient: HttpClient) {
    this.httpClient.get('/url', {
      params: {
        appid: 'id1234',
        cnt: '5'
      },
      observe: 'response'
    })
    .toPromise()
    .then(response => {
      console.log(response);
    })
    .catch(console.log);
  }
}

For angular versions prior to version 4 you can do the same using the Http service.

The Http.get method takes an object that implements RequestOptionsArgs as a second parameter.

The search field of that object can be used to set a string or a URLSearchParams object.

An example:

 // Parameters obj-
 let params: URLSearchParams = new URLSearchParams();
 params.set('appid', StaticSettings.API_KEY);
 params.set('cnt', days.toString());

 //Http request-
 return this.http.get(StaticSettings.BASE_URL, {
   search: params
 }).subscribe(
   (response) => this.onGetForecastResult(response.json()), 
   (error) => this.onGetForecastError(error.json()), 
   () => this.onGetForecastComplete()
 );

The documentation for the Http class has more details. It can be found here and an working example here.

Here's an example of a transaction that will rollback on error and return the error code.

As someone who doesn't know javascript, here's a PHP method that works for me and is easy to understand. My whole navbar is in a PHP function that is in a file of common components I include from my pages. So for example in my 'index.php' page I have... `

<?php
   $calling_file = basename(__FILE__);
   include 'my_common_includes.php';    // Going to use my navbar function "my_navbar"
   my_navbar($calling_file);    // Call the navbar function
 ?>

Then in the 'my_common_includes.php' I have...

<?php
   function my_navbar($calling_file)
   {
      // All your usual nabvbar code here up to the menu items
      if ($calling_file=="index.php")   {   echo '<li class="nav-item active">';    } else {    echo '<li class="nav-item">';   }
    echo '<a class="nav-link" href="index.php">Home</a>
</li>';
      if ($calling_file=="about.php")   {   echo '<li class="nav-item active">';    } else {    echo '<li class="nav-item">';   }
    echo '<a class="nav-link" href="about.php">About</a>
</li>';
      if ($calling_file=="galleries.php")   {   echo '<li class="nav-item active">';    } else {    echo '<li class="nav-item">';   }
    echo '<a class="nav-link" href="galleries.php">Galleries</a>
</li>';
       // etc for the rest of the menu items and closing out the navbar
     }
  ?>

DBSIZE returns the number of keys and it's easier to parse.

Downside: if a key has expired it may still count.

Regarding the 64-bit system wanting 32-bit support. I don't find it so bizarre:

Although deployed to a 64-bit system, this doesn't mean all the referenced assemblies are necessarily 64-bit Crystal Reports assemblies. Further to that, the Crystal Reports assemblies are largely just wrappers to a collection of legacy DLLs upon which they are based. Many 32-bit DLLs are required by the primarily referenced assembly. The error message "can not load the assembly" involves these DLLs as well. To see visually what those are, go to www.dependencywalker.com and run 'Depends' on the assembly in question, directly on that IIS server.

net use "m:\Server01\my folder" /USER:mynetwork\Administrator "Mypassword" /persistent:yes 

does not work?

(2019) I used $('#'+id).removeAttr().off('click').on('click', function(){...});

I tried $('#'+id).off().on(...), but it wouldn't work to reset the onClick attribute every time it was called to be reset.

I use .on('click',function(){...}); to stay away from having to quote block all my javascript functions.

The O.P. could now use:

$(this).removeAttr('onclick').off('click').on('click', function(){ displayCalendar(document.prjectFrm[ia + 'dtSubDate'],'yyyy-mm-dd', this); });

Where this came through for me is when my div was set with the onClick attribute set statically:

<div onclick = '...'>

Otherwise, if I only had a dynamically attached a listener to it, I would have used the $('#'+id).off().on('click', function(){...});.

Without the off('click') my onClick listeners were being appended not replaced.

When you want to open an activity within your app then you can call the startActivity() method with an Intent as parameter. That intent would be the activity that you want to open. First you have to create an object of that intent with first parameter to be the context and second parameter to be the targeted activity class.

Intent intent = new Intent(this, Activity_a.class);
startActivity(intent);

Hope this will help.

Surprising that after such a long time there is still the best answer missing.

The downside of the other answers is using [0] to select the first character, but as noted, this breaks on the empty string.

Using the following circumvents this problem, and, in my opinion, gives the prettiest and most readable syntax of the options we have. It also does not import/bother with regex either):

>>> string = '1abc'
>>> string[:1].isdigit()
True

>>> string = ''
>>> string[:1].isdigit()
False

Be very very careful renaming objects in sql. You can cause dependencies to fail if you are not fully away with what you are doing. Having said that this works easily(too much so) for renaming things provided you have access proper on the environment:

exec sp_rename 'Nameofobject', 'ReNameofobject'

Not a single answer here actually answers the question. The OP did not ask about a singleton/per-application DbContext design, he asked about a per-(web)request design and what potential benefits could exist.

I'll reference http://mehdi.me/ambient-dbcontext-in-ef6/ as Mehdi is a fantastic resource:

Possible performance gains.

Each DbContext instance maintains a first-level cache of all the entities its loads from the database. Whenever you query an entity by its primary key, the DbContext will first attempt to retrieve it from its first-level cache before defaulting to querying it from the database. Depending on your data query pattern, re-using the same DbContext across multiple sequential business transactions may result in a fewer database queries being made thanks to the DbContext first-level cache.

It enables lazy-loading.

If your services return persistent entities (as opposed to returning view models or other sorts of DTOs) and you'd like to take advantage of lazy-loading on those entities, the lifetime of the DbContext instance from which those entities were retrieved must extend beyond the scope of the business transaction. If the service method disposed the DbContext instance it used before returning, any attempt to lazy-load properties on the returned entities would fail (whether or not using lazy-loading is a good idea is a different debate altogether which we won't get into here). In our web application example, lazy-loading would typically be used in controller action methods on entities returned by a separate service layer. In that case, the DbContext instance that was used by the service method to load these entities would need to remain alive for the duration of the web request (or at the very least until the action method has completed).

Keep in mind there are cons as well. That link contains many other resources to read on the subject.

Just posting this in case someone else stumbles upon this question and doesn't get absorbed in answers that don't actually address the question.

If you're unable to make it work at the <ul> level, you might need to place the list-style-type: none; at the <li> level:

<ul>
    <li style="list-style-type: none;">Item 1</li>
    <li style="list-style-type: none;">Item 2</li>
</ul>

You can create a CSS class to avoid this repetition:

<style>
ul.no-bullets li
{
    list-style-type: none;
}
</style>

<ul class="no-bullets">
    <li>Item 1</li>
    <li>Item 2</li>
</ul>

When necessary, use !important:

<style>
ul.no-bullets li
{
    list-style-type: none !important;
}
</style>

I did not know that even with the "Allow Installation of non-Marked application", I still needed to sign the application.

I self-signed my application, following this link self-sign and release application, It only took 5 minutes, then I emailed the signed-APK file to myself and downloaded it to SD-card and then installed it without any problem.

According to the Documentation :

MailMessage.To property - Returns MailAddressCollection that contains the list of recipients of this email message

Here MailAddressCollection has a in built method called

   public void Add(string addresses)

   1. Summary:
          Add a list of email addresses to the collection.

   2. Parameters:
          addresses: 
                *The email addresses to add to the System.Net.Mail.MailAddressCollection. Multiple
                *email addresses must be separated with a comma character (",").     

Therefore requirement in case of multiple recipients : Pass a string that contains email addresses separated by comma

In your case :

simply replace all the ; with ,

Msg.To.Add(toEmail.replace(";", ","));

For reference :

Firstly, your URL definition does not accept any parameters at all. If you want parameters to be passed from the URL into the view, you need to define them in the urlconf.

Secondly, it's not at all clear what you are expecting to happen to the cleaned_data dictionary. Don't forget you can't redirect to a POST - this is a limitation of HTTP, not Django - so your cleaned_data either needs to be a URL parameter (horrible) or, slightly better, a series of GET parameters - so the URL would be in the form:

/link/mybackend/?field1=value1&field2=value2&field3=value3

and so on. In this case, field1, field2 and field3 are not included in the URLconf definition - they are available in the view via request.GET.

So your urlconf would be:

url(r'^link/(?P<backend>\w+?)/$', my_function)

and the view would look like:

def my_function(request, backend):
   data = request.GET

and the reverse would be (after importing urllib):

return "%s?%s" % (redirect('my_function', args=(backend,)),
                  urllib.urlencode(form.cleaned_data))

Edited after comment

The whole point of using redirect and reverse, as you have been doing, is that you go to the URL - it returns an Http code that causes the browser to redirect to the new URL, and call that.

If you simply want to call the view from within your code, just do it directly - no need to use reverse at all.

That said, if all you want to do is store the data, then just put it in the session:

request.session['temp_data'] = form.cleaned_data

My preferred option is very fast, I sampled a tab-delimited data file with 13 columns, 23.1M rows, 2.0GB uncompressed.

# randomly sample select 5% of lines in file
# including header row, exclude blank lines, new seed

time \
awk 'BEGIN  {srand()} 
     !/^$/  { if (rand() <= .05 || FNR==1) print > "data-sample.txt"}' data.txt

# awk  tsv004  3.76s user 1.46s system 91% cpu 5.716 total

Use the following will help

keytool -import -v -trustcacerts -alias keyAlias -file server.cer -keystore cacerts.jks -keypass changeit

In Python 3 this is no longer an issue, and you really don't want to use list comprehension, coercion, filters, functions or lambdas for something like this.

Just use

popped = unpopped[:-1]

Remember that it's an immutable, so you will have to reassign the value if you want it to change

my_tuple = my_tuple[:-1]

Example

>>> foo= 3,5,2,4,78,2,1
>>> foo
(3, 5, 2, 4, 78, 2, 1)
foo[:-1]
(3, 5, 2, 4, 78, 2)

The easiest way to do this would be to put a link on your column headers, pointing to the same page. In the query string, put a variable so that you know what they clicked on, and then use ORDER BY in your SQL query to perform the ordering.

The HTML would look like this:

<th><a href="mypage.php?sort=type">Type:</a></th>
<th><a href="mypage.php?sort=desc">Description:</a></th>
<th><a href="mypage.php?sort=recorded">Recorded Date:</a></th>
<th><a href="mypage.php?sort=added">Added Date:</a></th>

And in the php code, do something like this:

<?php

$sql = "SELECT * FROM MyTable";

if ($_GET['sort'] == 'type')
{
    $sql .= " ORDER BY type";
}
elseif ($_GET['sort'] == 'desc')
{
    $sql .= " ORDER BY Description";
}
elseif ($_GET['sort'] == 'recorded')
{
    $sql .= " ORDER BY DateRecorded";
}
elseif($_GET['sort'] == 'added')
{
    $sql .= " ORDER BY DateAdded";
}

$>

Notice that you shouldn't take the $_GET value directly and append it to your query. As some user could got to MyPage.php?sort=; DELETE FROM MyTable;

An easy way is to convert the dates into milliseconds after January 1, 1970 (use Date.getTime()) and then compare these values.

layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent" >

  <LinearLayout
      android:id="@+id/layoutTest"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:orientation="vertical"
      >
  </LinearLayout>
</RelativeLayout>

class file:

setContentView(R.layout.layout_dynamic);
layoutTest=(LinearLayout)findViewById(R.id.layoutTest);
TextView textView = new TextView(getApplicationContext());

textView.setText("testDynamic textView");
layoutTest.addView(textView);

If you're happy you know what you're doing and can accept the portability problems, on GCC for example you can disable the warning on the command line:

-Wno-multichar

I use this for my own apps to work with AVI and MP4 file headers for similar reasons to you.

Maybe you can use this solution through :before:

    display: inline-block;_x000D_
    position: relative;_x000D_
}_x000D_
_x000D_
nav li a {_x000D_
    display: inline-block;_x000D_
    padding: 10px 20px;_x000D_
}_x000D_
_x000D_
nav li a:hover {_x000D_
    color: red;_x000D_
}_x000D_
_x000D_
nav li.disabled:before {_x000D_
    content: '';_x000D_
    position: absolute;_x000D_
    top: 0;_x000D_
    left: 0;_x000D_
    bottom: 0;_x000D_
    right: 0;_x000D_
}

<nav>_x000D_
    <ul>_x000D_
    <li><a href="#">Link</a></li>_x000D_
    <li class="disabled"><a href="#">Link</a></li>_x000D_

Ctrl+C is what you need. If it didn't work, hit it harder. :-) Of course, you can also just close the shell window.

Edit: You didn't mention the circumstances. As a last resort, you could write a batch file that contains taskkill /im python.exe, and put it on your desktop, Start menu, etc. and run it when you need to kill a runaway script. Of course, it will kill all Python processes, so be careful.

Eg:

if 'newsletter_sub' in request.POST:
    # do subscribe
elif 'newsletter_unsub' in request.POST:
    # do unsubscribe

A couple of issues

• You're not limiting it to files, so when it finds a matching directory it will list every file within it.
• You can't use > in -exec without something like bash -c '... > ...'. Though the > will overwrite the file, so you want to redirect the entire find anyway rather than each -exec.
• +30 is older than 30 days, -30 would be modified in last 30 days.
• -exec really isn't needed, you could list everything with various -printf options.

Something like below should work

find . -type f -mtime -30 -exec ls -l {} \; > last30days.txt

Example with -printf

find . -type f -mtime -30 -printf "%M %u %g %TR %TD %p\n" > last30days.txt

This will list files in format "permissions owner group time date filename". -printf is generally preferable to -exec in cases where you don't have to do anything complicated. This is because it will run faster as a result of not having to execute subshells for each -exec. Depending on the version of find, you may also be able to use -ls, which has a similar format to above.

Check your servers error log, typically /var/log/apache2/error.log.

Reference to http://developer.android.com/training/basics/activity-lifecycle/starting.html

onResume() Called just before the activity starts interacting with the user. At this point the activity is at the top of the activity stack, with user input going to it. Always followed by onPause().

onPause() Called when the system is about to start resuming another activity. This method is typically used to commit unsaved changes to persistent data, stop animations and other things that may be consuming CPU, and so on. It should do whatever it does very quickly, because the next activity will not be resumed until it returns. Followed either by onResume() if the activity returns back to the front, or by onStop() if it becomes invisible to the user.

you can first remove if there is / at the end and then get last part of url

let locationLastPart = window.location.pathname
if (locationLastPart.substring(locationLastPart.length-1) == "/") {
  locationLastPart = locationLastPart.substring(0, locationLastPart.length-1);
}
locationLastPart = locationLastPart.substr(locationLastPart.lastIndexOf('/') + 1);

I was running some of the answers to see what is the fastest way for a large number. So, I found that we can convert the int to an array and it can give the correct results and it is faster.

  arrayint=np.array(myInt)
  newList = myList / arrayint

This a comparison of all answers above

import numpy as np
import time
import random
myList = random.sample(range(1, 100000), 10000)
myInt = 10
start_time = time.time()
arrayint=np.array(myInt)
newList = myList / arrayint
end_time = time.time()
print(newList,end_time-start_time)
start_time = time.time()
newList = np.array(myList) / myInt
end_time = time.time()
print(newList,end_time-start_time)
start_time = time.time()
newList = [x / myInt for x in myList]
end_time = time.time()
print(newList,end_time-start_time)
start_time = time.time()
myList[:] = [x / myInt for x in myList]
end_time = time.time()
print(newList,end_time-start_time)
start_time = time.time()
newList = map(lambda x: x/myInt, myList)
end_time = time.time()
print(newList,end_time-start_time)
start_time = time.time()
newList = [i/myInt for i in myList]
end_time = time.time()
print(newList,end_time-start_time)
start_time = time.time()
newList  = np.divide(myList, myInt)
end_time = time.time()
print(newList,end_time-start_time)
start_time = time.time()
newList  = np.divide(myList, myInt)
end_time = time.time()
print(newList,end_time-start_time)

I use Bitbucket with the Eclipse IDE with the Eclipse EGit plugin installed.

I compare a file from any version of its history (like SVN).

Menu Project Explorer → File → right click → Team → Show in history.

This will bring the history of all changes on that file. Now Ctrl click and select any two versions→ "Compare with each other".

If you are using downloading data using url...may need to use

var result = client.DownloadData(url);

MD5 is perfectly fine if you don't need the best security, and if you're doing something like checking file integrity then security is not a consideration. In such as case you might want to consider something simpler and faster, such as Adler32, which is also supported by the Java libraries.

I would use ruby-build with rbenv. The following lines install Ruby 3.0.0 and set it as your default Ruby version:

$ brew update
$ brew install ruby-build
$ brew install rbenv

$ rbenv install 3.0.0
$ rbenv global 3.0.0

I like the explanation from this blog post:

The function New is a Go convention for packages that create a core type or different types for use by the application developer. Look at how New is defined and implemented in log.go, bufio.go and cypto.go:

log.go

// New creates a new Logger. The out variable sets the
// destination to which log data will be written.
// The prefix appears at the beginning of each generated log line.
// The flag argument defines the logging properties.
func New(out io.Writer, prefix string, flag int) * Logger {
    return &Logger{out: out, prefix: prefix, flag: flag}
}

bufio.go

// NewReader returns a new Reader whose buffer has the default size.
func NewReader(rd io.Reader) * Reader {
    return NewReaderSize(rd, defaultBufSize)
}

crypto.go

// New returns a new hash.Hash calculating the given hash function. New panics
// if the hash function is not linked into the binary.
func (h Hash) New() hash.Hash {
    if h > 0 && h < maxHash {
        f := hashes[h]
        if f != nil {
            return f()
        }
    }
    panic("crypto: requested hash function is unavailable")
}

Since each package acts as a namespace, every package can have their own version of New. In bufio.go multiple types can be created, so there is no standalone New function. Here you will find functions like NewReader and NewWriter.

I know your class is over, but in professional coding, let this be a lesson:

• "Deprecated" means "avoid use; it's going to be removed in the future"
• Deprecated things still work - just don't expect support or future-proofing
• If the requirement requires it, and you can't negotiate it away, just use the deprecated construct.
  
  • If you're really concerned, develop the alternative implementation on the side and keep it ready for the inevitable failure
  • Charge for the extra work now. By requesting a deprecated feature, they are asking you to double the work. You're going to see it again anyway, so might as well front-load it.
  • When the failure happens, let the interested party know that this was what you feared; that you prepared for it, but it'll take some time
  • Deploy your solution as quickly as you can (there will be bugs)
  • Gain rep for preventing excessive downtime.

I haven't timed it but I suspect this would be pretty quick:

import numpy as np
list1=[1, 2, 3]
list2=[4, 5, 6]

list_sum = (np.add(list1, list2)).tolist()

[5, 7, 9]

git branch -f <branchname> <commit>

I go with Mark Longair's solution and comments and recommend anyone reads those before acting, but I'd suggest the emphasis should be on

git branch -f <branchname> <commit>

Here is a scenario where I have needed to do this.

Scenario

Develop on the wrong branch and hence need to reset it.

Start Okay

Cleanly develop and release some software.

Develop on wrong branch

Mistake: Accidentally stay on the release branch while developing further.

Realize the mistake

"OH NO! I accidentally developed on the release branch." The workspace is maybe cluttered with half changed files that represent work-in-progress and we really don't want to touch and mess with. We'd just like git to flip a few pointers to keep track of the current state and put that release branch back how it should be.

Create a branch for the development that is up to date holding the work committed so far and switch to it.

git branch development
git checkout development 

Correct the branch

Now we are in the problem situation and need its solution! Rectify the mistake (of taking the release branch forward with the development) and put the release branch back how it should be.

Correct the release branch to point back to the last real release.

git branch -f release release2

The release branch is now correct again, like this ...

What if I pushed the mistake to a remote?

git push -f <remote> <branch> is well described in another thread, though the word "overwrite" in the title is misleading. Force "git push" to overwrite remote files

cross apply sometimes enables you to do things that you cannot do with inner join.

Example (a syntax error):

select F.* from sys.objects O  
inner join dbo.myTableFun(O.name) F   
on F.schema_id= O.schema_id

This is a syntax error, because, when used with inner join, table functions can only take variables or constants as parameters. (I.e., the table function parameter cannot depend on another table's column.)

However:

select F.* from sys.objects O  
cross apply ( select * from dbo.myTableFun(O.name) ) F  
where F.schema_id= O.schema_id

This is legal.

Edit: Or alternatively, shorter syntax: (by ErikE)

select F.* from sys.objects O  
cross apply dbo.myTableFun(O.name) F
where F.schema_id= O.schema_id

Edit:

Note: Informix 12.10 xC2+ has Lateral Derived Tables and Postgresql (9.3+) has Lateral Subqueries which can be used to a similar effect.

Use std::bitset

#include <bitset>
#include <iostream>

int main()
{
    int temp = 0x5E;
    std::bitset<sizeof(int)*CHAR_BITS>   bits(temp);

    // 0 -> bit 1
    // 2 -> bit 3
    std::cout << bits[2] << std::endl;
}

Create enum like this:

//Error Handling in swift
enum spendingError : Error{
case minus
case limit
}

Create method like:

 func calculateSpending(morningSpending:Double,eveningSpending:Double) throws ->Double{
if morningSpending < 0 || eveningSpending < 0{
    throw spendingError.minus
}
if (morningSpending + eveningSpending) > 100{
    throw spendingError.limit
}
return morningSpending + eveningSpending
}

Now check error is there or not and handle it:

do{
try calculateSpending(morningSpending: 60, eveningSpending: 50)
} catch spendingError.minus{
print("This is not possible...")
} catch spendingError.limit{
print("Limit reached...")
}

Try this instead.

The difference concerns redirecting POST, PUT and DELETE requests and what the expectations of the server are for the user agent behavior (RFC 2616):

Note: RFC 1945 and RFC 2068 specify that the client is not allowed to change the method on the redirected request. However, most existing user agent implementations treat 302 as if it were a 303 response, performing a GET on the Location field-value regardless of the original request method. The status codes 303 and 307 have been added for servers that wish to make unambiguously clear which kind of reaction is expected of the client.

Also, read Wikipedia article on the 30x redirection codes.

const url = "http://www.example.com/1234"
const id = url.split('/').pop();

Try this, it is much easier

The output gives 1234

Just right click in your project go Manage NuGet Packages search for Microsoft.AspNet.WebApi.Client install it and you will have access to the extension method.

Yes. It is a device hardware serial number and it is unique. So on api level 2.3 and above you can use android.os.Build.ANDROID_ID to get it. For below 2.3 API level use TelephonyManager.getDeviceID().

String.split seems to be much slower than StringTokenizer. The only advantage with split is that you get an array of the tokens. Also you can use any regular expressions in split. org.apache.commons.lang.StringUtils has a split method which works much more faster than any of two viz. StringTokenizer or String.split. But the CPU utilization for all the three is nearly the same. So we also need a method which is less CPU intensive, which I am still not able to find.

Here's my implementation, which behaves exactly as item in list (at least on 2.3)

res/layout/list_video_footer.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <TextView
        android:id="@+id/list_video_footer"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="@android:drawable/list_selector_background"
        android:clickable="true"
        android:gravity="center"
        android:minHeight="98px"
        android:text="@string/more"
        android:textColor="@color/bright_text_dark_focused"
        android:textSize="18dp"
        android:textStyle="bold" />

</FrameLayout>

res/color/bright_text_dark_focused.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_selected="true" android:color="#444"/>
    <item android:state_focused="true" android:color="#444"/>
    <item android:state_pressed="true" android:color="#444"/>
    <item android:color="#ccc"/>

</selector>

Sounds like a case for DefaultIfEmpty (untested code follows):

Dim x = (From y In context.MyTable _
         Where y.MyField = value _
         Select y.MyCounter).DefaultIfEmpty.Max

If you are using the Git Bash shell, you can use the following trick:

> webpage.html

This is actually the same as:

echo "" > webpage.html

Then, you can use git add webpage.html to stage the file.

You can make a .reg file and call start on it. You can export any part of the registry as a .reg file to see what the format is.

Format here:

This can be run on any Windows machine without installing other software.

When hosting your application on another service (like Heroku, Nodejitsu, and AWS), your host may independently configure the process.env.PORT variable for you; after all, your script runs in their environment.

Amazon's Elastic Beanstalk does this. If you try to set a static port value like 3000 instead of process.env.PORT || 3000 where 3000 is your static setting, then your application will result in a 500 gateway error because Amazon is configuring the port for you.

This is a minimal Express application that will deploy on Amazon's Elastic Beanstalk:

var express = require('express');
var app = express();

app.get('/', function (req, res) {
  res.send('Hello World!');
});

// use port 3000 unless there exists a preconfigured port
var port = process.env.PORT || 3000;

app.listen(port);

var formValues = {
    firstName: $('#firstName').val(),
    lastName: $('#lastName').val(),
    phone: $('#phoneNumber').val(),
    address: $('#address').val()
};

Note this will contain the values of the elements at the point in time the object literal was interpreted, not when the properties of the object are accessed. You'd need to write a getter for that.

In HTML5 there is no scrolling attribute because "its function is better handled by CSS" see http://www.w3.org/TR/html5-diff/ for other changes. Well and the CSS solution:

CSS solution:

HTML4's scrolling="no" is kind of an alias of the CSS's overflow: hidden, to do so it is important to set size attributes width/height:

iframe.noScrolling{
  width: 250px; /*or any other size*/
  height: 300px; /*or any other size*/
  overflow: hidden;
}

Add this class to your iframe and you're done:

<iframe src="http://www.example.com/" class="noScrolling"></iframe>

! IMPORTANT NOTE ! : overflow: hidden for <iframe> is not fully supported by all modern browsers yet(even chrome doesn't support it yet) so for now (2013) it's still better to use Transitional version and use scrolling="no" and overflow:hidden at the same time :)

UPDATE 2020: the above is still true, oveflow for iframes is still not supported by all majors

You can remove class active from all .tab and use $(this) to target current clicked .tab:

$(document).ready(function() {
    $(".tab").click(function () {
        $(".tab").removeClass("active");
        $(this).addClass("active");     
    });
});

Your code won't work because after removing class active from all .tab, you also add class active to all .tab again. So you need to use $(this) instead of $('.tab') to add the class active only to the clicked .tab anchor

Updated Fiddle

You could try letting the stream throw an exception on failure:

std::ifstream f;
//prepare f to throw if failbit gets set
std::ios_base::iostate exceptionMask = f.exceptions() | std::ios::failbit;
f.exceptions(exceptionMask);

try {
  f.open(fileName);
}
catch (std::ios_base::failure& e) {
  std::cerr << e.what() << '\n';
}

e.what(), however, does not seem to be very helpful:

• I tried it on Win7, Embarcadero RAD Studio 2010 where it gives "ios_base::failbit set" whereas strerror(errno) gives "No such file or directory."
• On Ubuntu 13.04, gcc 4.7.3 the exception says "basic_ios::clear" (thanks to arne)

If e.what() does not work for you (I don't know what it will tell you about the error, since that's not standardized), try using std::make_error_condition (C++11 only):

catch (std::ios_base::failure& e) {
  if ( e.code() == std::make_error_condition(std::io_errc::stream) )
    std::cerr << "Stream error!\n"; 
  else
    std::cerr << "Unknown failure opening file.\n";
}

I had the same problem on my mac, but in my case, the problem was that I did not run the database (sudo mongod) before; the problem was solved when I first ran the mondo sudod on the console and, once it was done, on another console, the connection to the server ...

I recently came across Python 3 interpreter at CompileOnline.

Boolean(val) === false. This worked for me to check if value was falsely.

You can use org.apache.commons.io.IOUtils.copy to copy the contents of the InputStream to a byte array, and then repeatedly read from the byte array using a ByteArrayInputStream. E.g.:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
org.apache.commons.io.IOUtils.copy(in, baos);
byte[] bytes = baos.toByteArray();

// either
while (needToReadAgain) {
    ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
    yourReadMethodHere(bais);
}

// or
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
while (needToReadAgain) {
    bais.reset();
    yourReadMethodHere(bais);
}

The compiler replaces null comparisons with a call to HasValue, so there is no real difference. Just do whichever is more readable/makes more sense to you and your colleagues.

Reference article: Show red color border for invalid input fields angualrjs

I used ng-class on all input fields.like below

<input type="text" ng-class="{submitted:newEmployee.submitted}" placeholder="First Name" data-ng-model="model.firstName" id="FirstName" name="FirstName" required/>

when I click on save button I am changing newEmployee.submitted value to true(you can check it in my question). So when I click on save, a class named submitted gets added to all input fields(there are some other classes initially added by angularjs).

So now my input field contains classes like this

class="ng-pristine ng-invalid submitted"

now I am using below css code to show red border on all invalid input fields(after submitting the form)

input.submitted.ng-invalid
{
  border:1px solid #f00;
}

Thank you !!

Update:

We can add the ng-class at the form element instead of applying it to all input elements. So if the form is submitted, a new class(submitted) gets added to the form element. Then we can select all the invalid input fields using the below selector

form.submitted .ng-invalid
{
    border:1px solid #f00;
}

In Linux file system , Edit below file as this steps

Path - /opt/glassfish3/glassfish/config

File Name - asenv.conf

Add the JAVA HOME path as below to the end of file.

AS_JAVA=/opt/jdk1.8.0_201

Now start the glassfish server.

There is no other option other than a hidden field, so try to use a hidden field like demonstrated in the code below:

<input type="hidden" type="text" name="chk1[]" id="tasks" value="xyz" >
<input class="display_checkbox" type="checkbox" name="chk1[]" id="tasks" value="xyz" checked="check"  disabled="disabled" >Tasks

Prefer the MsBuild "Copy" task in an AfterBuild target over a post-build event.

Append this Target into your project file and remove the PostBuildEvent.

<Target Name="AfterBuild">
    <Copy SourceFiles="C:\Users\scogan\Documents\Visual Studio 2012\Projects\Organizr\Server\bin\Debug\Organizr.Services.*" 
          DestinationFolder="C:\inetpub\wwwroot\AppServer\bin\" 
          OverwriteReadOnlyFiles="true" 
          SkipUnchangedFiles="false" />
</Target>

You can also use sqlcmd mode for this (enable this on the "Query" menu in Management Studio).

:setvar dbname "TEST" 

CREATE DATABASE $(dbname)
GO
ALTER DATABASE $(dbname) SET COMPATIBILITY_LEVEL = 90
GO
ALTER DATABASE $(dbname) SET RECOVERY SIMPLE 
GO

EDIT:

Check this MSDN article to set parameters via the SQLCMD tool.

If you're developing for android, you're somewhat tied to Eclipse (edit: at time of writing, not anymore), which has its own annotations. It's included in Eclipse 3.8+ (Juno), but disabled by default.

You can enable it at Preferences > Java > Compiler > Errors/Warnings > Null analysis (collapsable section at the bottom).

Check "Enable annotation-based null analysis"

http://wiki.eclipse.org/JDT_Core/Null_Analysis#Usage has recommendations on settings. However, if you have external projects in your workspace (like the facebook SDK), they may not satisfy those recommendations, and you probably don't want to fix them with each SDK update ;-)

I use:

1. Null pointer access: Error
2. Violation of null specification: Error (linked to point #1)
3. Potential null pointer access: Warning (otherwise facebook SDK would have warnings)
4. Conflict between null annotations and null inference: Warning (linked to point #3)

I wrote an updated version of Kees C. Bakker's answer:

const hasVerticalScroll = (node) => {
  if (!node) {
    if (window.innerHeight) {
      return document.body.offsetHeight > window.innerHeight
    }
    return (document.documentElement.scrollHeight > document.documentElement.offsetHeight)
      || (document.body.scrollHeight > document.body.offsetHeight)
  }
  return node.scrollHeight > node.offsetHeight
}

if (hasVerticalScroll(document.querySelector('body'))) {
  this.props.handleDisableDownScrollerButton()
}

The function returns true or false depending whether the page has a vertical scrollbar or not.

For example:

const hasVScroll = hasVerticalScroll(document.querySelector('body'))

if (hasVScroll) {
  console.log('HAS SCROLL', hasVScroll)
}

if ($request->hasFile('input_img')) {
    if($request->file('input_img')->isValid()) {
        try {
            $file = $request->file('input_img');
            $name = time() . '.' . $file->getClientOriginalExtension();

            $request->file('input_img')->move("fotoupload", $name);
        } catch (Illuminate\Filesystem\FileNotFoundException $e) {

        }
    } 
}

Personally I find

if (id in tutorTimes === false) { ... }

easier to read than

if (!(id in tutorTimes)) { ... }

but both will work.

I also experienced this error when working with CMake:

No CMAKE_C_COMPILER could be found.
No CMAKE_CXX_COMPILER could be found.

The 'warning' box in the MSDN library article Visual C++ in Visual Studio 2015 gave me the help that I needed.

Visual Studio 2015 doesn't come with C++ installed by default. So, creating a new C++ project will prompt you to download the necessary C++ components.

Yes! By passing a stream context in the third parameter:

This may also be because you might have given classname with all letters in lowercase something which groovy (know of version 2.5.0) does not support.

You can use setenv.bat or .sh to pass the environment variables to the Tomcat.

Create CATALINA_BASE/bin/setenv.bat or .sh file and put the following line in it, and then start the Tomcat.

On Windows:

set APP_MASTER_PASSWORD=foo

On Unix like systems:

export APP_MASTER_PASSWORD=foo

Generetic Action Sheet working for Swift 4, 4.2, 5

If you like a generic version that you can call from every ViewController and in every project try this one:

class Alerts {
 static func showActionsheet(viewController: UIViewController, title: String, message: String, actions: [(String, UIAlertActionStyle)], completion: @escaping (_ index: Int) -> Void) {
    let alertViewController = UIAlertController(title: title, message: message, preferredStyle: .actionSheet)
    for (index, (title, style)) in actions.enumerated() {
        let alertAction = UIAlertAction(title: title, style: style) { (_) in
            completion(index)
        }
        alertViewController.addAction(alertAction)
     }
     viewController.present(alertViewController, animated: true, completion: nil)
    }
}

Call like this in your ViewController.

    var actions: [(String, UIAlertActionStyle)] = []
    actions.append(("Action 1", UIAlertActionStyle.default))
    actions.append(("Action 2", UIAlertActionStyle.destructive))
    actions.append(("Action 3", UIAlertActionStyle.cancel))

    //self = ViewController
    Alerts.showActionsheet(viewController: self, title: "D_My ActionTitle", message: "General Message in Action Sheet", actions: actions) { (index) in
        print("call action \(index)")
        /*
         results
         call action 0
         call action 1
         call action 2
         */
    }

Attention: Maybe you're wondering why I add Action 1/2/3 but got results like 0,1,2. In the line for (index, (title, style)) in actions.enumerated() I get the index of actions. Arrays always begin with the index 0. So the completion is 0,1,2.

If you like to set a enum, an id or another identifier I would recommend to hand over an object in parameter actions.

You can use %%~nf to get the filename only as described in the reference for for:

@echo off
    for /R "C:\Users\Admin\Ordner" %%f in (*.flv) do (
    echo %%~nf
)
pause

The following options are available:

Variable with modifier  Description

%~I                     Expands %I which removes any surrounding 
                        quotation marks ("").
%~fI                    Expands %I to a fully qualified path name.
%~dI                    Expands %I to a drive letter only.
%~pI                    Expands %I to a path only.
%~nI                    Expands %I to a file name only.
%~xI                    Expands %I to a file extension only.
%~sI                    Expands path to contain short names only.
%~aI                    Expands %I to the file attributes of file.
%~tI                    Expands %I to the date and time of file.
%~zI                    Expands %I to the size of file.
%~$PATH:I               Searches the directories listed in the PATH environment 
                        variable and expands %I to the fully qualified name of 
                        the first one found. If the environment variable name is 
                        not defined or the file is not found by the search,
                        this modifier expands to the empty string.    

This worked for me:

<button #loginButton ...

and inside the controller:

@ViewChild('loginButton') loginButton;
...
this.loginButton.getNativeElement().click();

Milox solution is better than the accepted one IMHO but I had some problems with this implementation when handling urls with querystring.

I made some changes to make it work properly with any urls and to avoid Reflection.

public static HttpContext FakeHttpContext(string url)
{
    var uri = new Uri(url);
    var httpRequest = new HttpRequest(string.Empty, uri.ToString(),
                                        uri.Query.TrimStart('?'));
    var stringWriter = new StringWriter();
    var httpResponse = new HttpResponse(stringWriter);
    var httpContext = new HttpContext(httpRequest, httpResponse);

    var sessionContainer = new HttpSessionStateContainer("id",
                                    new SessionStateItemCollection(),
                                    new HttpStaticObjectsCollection(),
                                    10, true, HttpCookieMode.AutoDetect,
                                    SessionStateMode.InProc, false);

    SessionStateUtility.AddHttpSessionStateToContext(
                                         httpContext, sessionContainer);

    return httpContext;
}

var inp = $("#txt").val();
if(jQuery.trim(inp).length > 0)
{
   //do something
}

Removes white space before checking. If the user entered only spaces then this will still work.

CoolAJ86's solution is correct and it does not compromise your security like disabling all checks using rejectUnauthorized or NODE_TLS_REJECT_UNAUTHORIZED. Still, you may need to inject an additional CA's certificate explicitly.

I tried first the root CAs included by the ssl-root-cas module:

require('ssl-root-cas/latest')
  .inject();

I still ended up with the UNABLE_TO_VERIFY_LEAF_SIGNATURE error. Then I found out who issued the certificate for the web site I was connecting to by the COMODO SSL Analyzer, downloaded the certificate of that authority and tried to add only that one:

require('ssl-root-cas/latest')
  .addFile(__dirname + '/comodohigh-assurancesecureserverca.crt');

I ended up with another error: CERT_UNTRUSTED. Finally, I injected the additional root CAs and included "my" (apparently intermediary) CA, which worked:

require('ssl-root-cas/latest')
  .inject()
  .addFile(__dirname + '/comodohigh-assurancesecureserverca.crt');

There were a few ways I found to do this:

• Firefox: Add Exception -> Get Certificat -> View -> Details -> Export...
• KeyMan (http://www.alphaworks.ibm.com/tech/keyman) You can get SSL cert directly from the File -> Import menu
• InstallCert (Code by Andreas Sterbenz)

    java InstallCert [host]:[port] 
    keytool -exportcert -keystore jssecacerts -storepass changeit -file output.cert
    keytool -importcert -keystore [DESTINATION_KEYSTORE] -file output.cert

There are two options here.

1. a hidden field within the form, or
2. Add it to the route values parameter in the begin form method.

Edit

@Html.Hidden("clubid", ViewBag.Club.id)

or

 @using(Html.BeginForm("action", "controller",
                       new { clubid = @Viewbag.Club.id }, FormMethod.Post, null)

I generated a node/gulp app using the generator-gulp-webapp Yeoman generator. It handled the "clean conundrum" this way (translating to the original tasks mentioned in the question):

gulp.task('develop', ['clean'], function () {
  gulp.start('coffee');
});

Example:

Process process = Process.Start(@"Data\myApp.exe");
int id = process.Id;
Process tempProc = Process.GetProcessById(id);
this.Visible = false;
tempProc.WaitForExit();
this.Visible = true;

My conclusion is that(Tested on 12c):

• AS is always optional, either with or without ""; AS makes no difference (column alias only, you can not use AS preceding table alias)
• However, with or without "" does make difference because "" lets lower case possible for an alias

thus :

SELECT {T / t} FROM (SELECT 1 AS T FROM DUAL); -- Correct
SELECT "tEST" FROM (SELECT 1 AS "tEST" FROM DUAL); -- Correct
SELECT {"TEST" / tEST} FROM (SELECT 1 AS "tEST" FROM DUAL ); -- Incorrect

SELECT test_value AS "doggy" FROM test ORDER BY "doggy"; --Correct
SELECT test_value AS "doggy" FROM test WHERE "doggy" IS NOT NULL; --You can not do this, column alias not supported in WHERE & HAVING
SELECT * FROM test "doggy" WHERE "doggy".test_value IS NOT NULL; -- Do not use AS preceding table alias

So, the reason why USING AS AND "" causes problem is NOT AS

Note: "" double quotes are required if alias contains space OR if it contains lower-case characters and MUST show-up in Result set as lower-case chars. In all other scenarios its OPTIONAL and can be ignored.

I wanted a function that would join tables without requiring you to define the columns using an anonymous type selector, but had a hard time finding any. I ended up having to make my own. Hopefully this will help anyone in the future who searches for this:

private DataTable JoinDataTables(DataTable t1, DataTable t2, params Func<DataRow, DataRow, bool>[] joinOn)
{
    DataTable result = new DataTable();
    foreach (DataColumn col in t1.Columns)
    {
        if (result.Columns[col.ColumnName] == null)
            result.Columns.Add(col.ColumnName, col.DataType);
    }
    foreach (DataColumn col in t2.Columns)
    {
        if (result.Columns[col.ColumnName] == null)
            result.Columns.Add(col.ColumnName, col.DataType);
    }
    foreach (DataRow row1 in t1.Rows)
    {
        var joinRows = t2.AsEnumerable().Where(row2 =>
            {
                foreach (var parameter in joinOn)
                {
                    if (!parameter(row1, row2)) return false;
                }
                return true;
            });
        foreach (DataRow fromRow in joinRows)
        {
            DataRow insertRow = result.NewRow();
            foreach (DataColumn col1 in t1.Columns)
            {
                insertRow[col1.ColumnName] = row1[col1.ColumnName];
            }
            foreach (DataColumn col2 in t2.Columns)
            {
                insertRow[col2.ColumnName] = fromRow[col2.ColumnName];
            }
            result.Rows.Add(insertRow);
        }
    }
    return result;
}

An example of how you might use this:

var test = JoinDataTables(transactionInfo, transactionItems,
               (row1, row2) =>
               row1.Field<int>("TransactionID") == row2.Field<int>("TransactionID"));

One caveat: This is certainly not optimized, so be mindful when getting to row counts above 20k. If you know that one table will be larger than the other, try to put the smaller one first and the larger one second.

To calculate the mean, loop through the list/array of numbers, keeping track of the partial sums and the length. Then return the sum/length.

double sum = 0.0;
int length = 0;

for( double number : numbers ) {
    sum += number;
    length++;
}

return sum/length;

Variance is calculated similarly. Standard deviation is simply the square root of the variance:

double stddev = Math.sqrt( variance );

Recursively/deep update a dict

def deepupdate(original, update):
    """
    Recursively update a dict.
    Subdict's won't be overwritten but also updated.
    """
    for key, value in original.iteritems(): 
        if key not in update:
            update[key] = value
        elif isinstance(value, dict):
            deepupdate(value, update[key]) 
    return update

Demonstration:

pluto_original = {
    'name': 'Pluto',
    'details': {
        'tail': True,
        'color': 'orange'
    }
}

pluto_update = {
    'name': 'Pluutoo',
    'details': {
        'color': 'blue'
    }
}

print deepupdate(pluto_original, pluto_update)

Outputs:

{
    'name': 'Pluutoo',
    'details': {
        'color': 'blue',
        'tail': True
    }
}

You have to close that application first. There is no way to delete it, if it's used by some application.

UnLock IT is a neat utility that helps you to take control of any file or folder when it is locked by some application or system. For every locked resource, you get a list of locking processes and can unlock it by terminating those processes. EMCO Unlock IT offers Windows Explorer integration that allows unlocking files and folders by one click in the context menu.

There's also Unlocker (not recommended, see Warning below), which is a free tool which helps locate any file locking handles running, and give you the option to turn it off. Then you can go ahead and do anything you want with those files.

Warning: The installer includes a lot of undesirable stuff. You're almost certainly better off with UnLock IT.

Changing Command Execute Timeout in Management Studio:

Click on Tools -> Options

Select Query Execution from tree on left side and enter command timeout in "Execute Timeout" control.

Changing Command Timeout in Server:

In the object browser tree right click on the server which give you timeout and select "Properties" from context menu.

Now in "Server Properties -....." dialog click on "Connections" page in "Select a Page" list (on left side). On the right side you will get property

Remote query timeout (in seconds, 0 = no timeout):
[up/down control]

you can set the value in up/down control.

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);

I am not sure if there is a mysql version of this but adding this line of code allows throwing mysqli_sql_exception.
I know, passed a lot of time and the question is already checked answered but I got a different answer and it may be helpful.

This was just asked a couple of days ago (but I cannot find it):

>>> A = [6, 7, 8, 9, 10, 11, 12]
>>> subset_of_A = set([6, 9, 12])
>>> [i for i in A if i not in subset_of_A]
[7, 8, 10, 11]

It might be better to use sets from the beginning, depending on the context. Then you can use set operations like other answers show.

However, converting lists to sets and back only for these operations is slower than list comprehension.

FOR A ONE LINER SOLUTION, type the following in Command prompt or Terminal at project root.

echo node_modules > .dockerignore

This creates the extension-less . prefixed file without any issue. Replace node_modules with the folder you want to exclude.

In ASP.NET, when should I use Session.Clear() rather than Session.Abandon()?

Session.Abandon() destroys the session and the Session_OnEnd event is triggered.

Session.Clear() just removes all values (content) from the Object. The session with the same key is still alive.

So, if you use Session.Abandon(), you lose that specific session and the user will get a new session key. You could use it for example when the user logs out.

Use Session.Clear(), if you want that the user remaining in the same session (if you don't want him to relogin for example) and reset all his session specific data.

What is the difference between Session.Abandon() and Session.Clear()

Clear - Removes all keys and values from the session-state collection.

Abandon - removes all the objects stored in a Session. If you do not call the Abandon method explicitly, the server removes these objects and destroys the session when the session times out. It also raises events like Session_End.

Session.Clear can be compared to removing all books from the shelf, while Session.Abandon is more like throwing away the whole shelf.

...

Generally, in most cases you need to use Session.Clear. You can use Session.Abandon if you are sure the user is going to leave your site.

So back to the differences:

• Abandon raises Session_End request.
• Clear removes items immediately, Abandon does not.
• Abandon releases the SessionState object and its items so it can garbage collected.
• Clear keeps SessionState and resources associated with it.

Session.Clear() or Session.Abandon() ?

You use Session.Clear() when you don't want to end the session but rather just clear all the keys in the session and reinitialize the session.

Session.Clear() will not cause the Session_End eventhandler in your Global.asax file to execute.

But on the other hand Session.Abandon() will remove the session altogether and will execute Session_End eventhandler.

Session.Clear() is like removing books from the bookshelf

Session.Abandon() is like throwing the bookshelf itself.

Question

I check on some sessions if not equal null in the page load. if one of them equal null i wanna to clear all the sessions and redirect to the login page?

Answer

If you want the user to login again, use Session.Abandon.

Too late for you, but for anyone else with the same question...

//a[contains(text(), 'programming')]/@href

Of course, 'programming' can be any text fragment.

Don't try to scan text with nextLine(); AFTER using nextInt() with the same scanner! It doesn't work well with Java Scanner, and many Java developers opt to just use another Scanner for integers. You can call these scanners scan1 and scan2 if you want.

You can use the transpose function from the data.table library. Simple and fast solution that keeps numeric values as numeric.

library(data.table)

# get data
  data("mtcars")

# transpose
  t_mtcars <- transpose(mtcars)

# get row and colnames in order
  colnames(t_mtcars) <- rownames(mtcars)
  rownames(t_mtcars) <- colnames(mtcars)

$myVar = str_replace('/', '', $_SERVER[REQUEST_URI]);

libs/images/index.php
Result: images

method = POST will work if you 'post' a form to the url /test.

if you type a url in address bar of a browser and hit enter, it's always a GET request, so you had to specify POST request.

Google for HTTP GET and HTTP POST (there are several others like PUT DELETE). They all have their own meaning.

This worked for me. Simplest solution by far.

If you are using GitHub for Windows and getting this error, the problem might be that you are trying to run the command in the wrong shell or mode. If you are trying to do git push origin master in the regular command prompt or PowerShell, this is the problem.

You need to do it in a git shell. Simply open Github for Windows, right click, and select "Open Shell Here". It looks like a regular PowerShell window, but it's not, which makes it really confusing for newbies to git, like myself.

I hope others find this useful.

The steps I needed to perform were:

1. Add reference to System.Web.Http.WebHost.
2. Add App_Start\WebApiConfig.cs (see code snippet below).
3. Import namespace System.Web.Http in Global.asax.cs.
4. Call WebApiConfig.Register(GlobalConfiguration.Configuration) in MvcApplication.Application_Start() (in file Global.asax.cs), before registering the default Web Application route as that would otherwise take precedence.
5. Add a controller deriving from System.Web.Http.ApiController.

I could then learn enough from the tutorial (Your First ASP.NET Web API) to define my API controller.

App_Start\WebApiConfig.cs:

using System.Web.Http;

class WebApiConfig
{
    public static void Register(HttpConfiguration configuration)
    {
        configuration.Routes.MapHttpRoute("API Default", "api/{controller}/{id}",
            new { id = RouteParameter.Optional });
    }
}

Global.asax.cs:

using System.Web.Http;

...

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();

    RegisterGlobalFilters(GlobalFilters.Filters);
    WebApiConfig.Register(GlobalConfiguration.Configuration);
    RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}

Update 10.16.2015:

Word has it, the NuGet package Microsoft.AspNet.WebApi must be installed for the above to work.

You're passing the array into the function by copy. Only objects are passed by reference in PHP, and an array is not an object. Here's what you do (note the &)

function foo(&$arr) { # note the &
  $arr[3] = $arr[0]+$arr[1]+$arr[2];
}
$waffles = array(1,2,3);
foo($waffles);
echo $waffles[3]; # prints 6

That aside, I'm not sure why you would do that particular operation like that. Why not just return the sum instead of assigning it to a new array element?

I had to use Debug.print instead of Print, which works in the Immediate window.

Google will eventually block your IP when you exceed a certain amount of requests.

I know this is a little late, nevertheless i'm answering this for anyone still experiencing this issue on windows (USING XAMPP).

Step 1. Verify that there is a mismatch in your PHP version. To do this, open routes/web.php and create a simple route to return the php information like so:

Route::get('/', function() {
   return response()->json([
    'stuff' => phpinfo()
   ]);
})

and compare this with output from your command line

As we can see, in my case there is a mismatch, this usually happens if you have multiple versions of php installed.

Step 2. Add the php version being used by your xampp to your system path

Step 3. Verify that you have the extension enabled in your php.ini file. NB. Make sure you are editing the php.ini file that is shown under the 'loaded configuration file' entry in the results of phpinfo() command.

Another way is to use a simple wrapper around FileReader returning Observable:

  function toBase64(blob: Blob): Observable<string> {
    const reader = new FileReader();
    reader.readAsDataURL(blob);
    return fromEvent(reader, 'load')
      .pipe(map(() => (reader.result as string).split(',')[1]));
  }

Usage:

toBase64(blob).subscribe(base64 => console.log(base64));

The problem is that you might easily get into trouble since JavaScript have a lot of implicit conversions meaning...

var x = 0;
var isTrue = x == null;
var isFalse = x === null;

Which pretty soon becomes a problem. The best sample of why implicit conversion is "evil" can be taken from this code in MFC / C++ which actually will compile due to an implicit conversion from CString to HANDLE which is a pointer typedef type...

CString x;
delete x;

Which obviously during runtime does very undefined things...

Google for implicit conversions in C++ and STL to get some of the arguments against it...

if you want to use truncate use this:

SET FOREIGN_KEY_CHECKS = 0; 
TRUNCATE table $table_name; 
SET FOREIGN_KEY_CHECKS = 1;

In straight Javascript you could do something similar to the following:

var kvpairs = [];
var form = // get the form somehow
for ( var i = 0; i < form.elements.length; i++ ) {
   var e = form.elements[i];
   kvpairs.push(encodeURIComponent(e.name) + "=" + encodeURIComponent(e.value));
}
var queryString = kvpairs.join("&");

In short, this creates a list of key-value pairs (name=value) which is then joined together using "&" as a delimiter.

If you don't mind the index being negative, you can do:

>>> a = ["foo", "bar", "baz"]
>>> for i in range(len(a)):
...     print(~i, a[~i]))
-1 baz
-2 bar
-3 foo

Depending on the schema/account you are using to connect to the database, I would suspect you are missing a grant to the account you are using to connect to the database.

Connect as PCT account in the database, then grant the account you are using select access for the table.

grant select on pi_int to Account_used_to_connect

I have tried this and it worked:

define PROPp_START_DT = TO_DATE('01-SEP-1999')

select * from proposal where prop_start_dt = &PROPp_START_DT

Many good solutions have been provided already. However, if he text is provided in a very simple comma delimited format or similar, and speed is of importance, then I have for you a solution with a TABLE function (in PL/SQL). I have also provided a rundown of some other solutions.

Please see more on the Blog Entry on Parsing a CSV into multiple columns.

See documentation here: http://www.postgresql.org/docs/current/interactive/sql-altertable.html

ALTER TABLE tbl_name ALTER COLUMN col_name TYPE varchar (11);

You can copy all enumerable own properties of an object to a new one by Object.assign(target, ...sources):

trivial_object = Object.assign({}, non_trivial_object);

so in your scenario, it should be enough to change

ret.push(i);

to

ret.push(Object.assign({}, i));

There is no simple and elegant solution to the Redirect problem in ASP.Net WebForms. You can choose between the Dirty solution and the Tedious solution

Dirty: Response.Redirect(url) sends a redirect to the browser, and then throws a ThreadAbortedException to terminate the current thread. So no code is executed past the Redirect()-call. Downsides: It is bad practice and have performance implications to kill threads like this. Also, ThreadAbortedExceptions will show up in exception logging.

Tedious: The recommended way is to call Response.Redirect(url, false) and then Context.ApplicationInstance.CompleteRequest() However, code execution will continue and the rest of the event handlers in the page lifecycle will still be executed. (E.g. if you perform the redirect in Page_Load, not only will the rest of the handler be executed, Page_PreRender and so on will also still be called - the rendered page will just not be sent to the browser. You can avoid the extra processing by e.g. setting a flag on the page, and then let subsequent event handlers check this flag before before doing any processing.

(The documentation to CompleteRequest states that it "Causes ASP.NET to bypass all events and filtering in the HTTP pipeline chain of execution". This can easily be misunderstood. It does bypass further HTTP filters and modules, but it doesn't bypass further events in the current page lifecycle.)

The deeper problem is that WebForms lacks a level of abstraction. When you are in a event handler, you are already in the process of building a page to output. Redirecting in an event handler is ugly because you are terminating a partially generated page in order to generate a different page. MVC does not have this problem since the control flow is separate from rendering views, so you can do a clean redirect by simply returning a RedirectAction in the controller, without generating a view.

There is another way if all you want is the text up to the first line feed:

x='some
thing'

y=${x%$'\n'*}

After that y will contain some and nothing else (no line feed).

What is happening here?

We perform a parameter expansion substring removal (${PARAMETER%PATTERN}) for the shortest match up to the first ANSI C line feed ($'\n') and drop everything that follows (*).

PHP-ZIP needs some dependancies or library missing, depends on the image from Dockerfile you need to install them first

RUN set -eux \
   && apt-get update \
   && apt-get install -y libzip-dev zlib1g-dev \
   && docker-php-ext-install zip

#include <iostream>
#include <fstream>
#include <vector>
using namespace std;

int main()
{
fstream dataFile;
string name , word , new_word;
vector<string> test;
char fileName[80];
cout<<"Please enter the file name : ";
cin >> fileName;
dataFile.open(fileName);
if(dataFile.fail())
{
     cout<<"File can not open.\n";
     return 0;
}
cout<<"File opened.\n";
cout<<"Please enter the word : ";

cin >> new_word;
while (!dataFile.fail() && !dataFile.eof())
{
      dataFile >> name;
      test.push_back(name);
}
dataFile.close();

}

Here is an even shorter way of achieving this:

1) using Negative character class pattern matching

irb(main)> "((String1))"[/[^()]+/]
=> "String1"

^ - Matches anything NOT in the character class. Inside the charachter class, we have ( and )

Or with global substitution "AKA: gsub" like others have mentioned.

irb(main)> "((String1))".gsub(/[)(]/, '')
=> "String1"

A simple way is to set line-height to the height of the element.

Sorry for answering again on that question... I needed to embed the image.

I think the results @mice found are missleading. The observations might be correct for the font size of 60 but they turn much more different when the text is smaller. Eg. 10px. In that case the text is actually drawn BEYOND the bounds.

Sourcecode of the screenshot:

  @Override
  protected void onDraw( Canvas canvas ) {
    for( int i = 0; i < 20; i++ ) {
      int startSize = 10;
      int curSize = i + startSize;
      paint.setTextSize( curSize );
      String text = i + startSize + " - " + TEXT_SNIPPET;
      Rect bounds = new Rect();
      paint.getTextBounds( text, 0, text.length(), bounds );
      float top = STEP_DISTANCE * i + curSize;
      bounds.top += top;
      bounds.bottom += top;
      canvas.drawRect( bounds, bgPaint );
      canvas.drawText( text, 0, STEP_DISTANCE * i + curSize, paint );
    }
  }

It prints the byte in Hexadecimal format.

No format string: 13

'X2' format string: 0D

The following will return an ISO8601 and RFC3339-compliant UTC timestamp, including nanoseconds.

It uses strftime(), which works with struct timespec just as well as with struct timeval because all it cares about is the number of seconds, which both provide. Nanoseconds are then appended (careful to pad with zeros!) as well as the UTC suffix 'Z'.

Example output: 2021-01-19T04:50:01.435561072Z

#include <stdio.h>
#include <time.h>
#include <sys/time.h>

int utc_system_timestamp(char[]);

int main(void) {
    char buf[31];
    utc_system_timestamp(buf);
    printf("%s\n", buf);
}

// Allocate exactly 31 bytes for buf
int utc_system_timestamp(char buf[]) {
        const int bufsize = 31;
        struct timespec now;
        struct tm tm;
        int retval = clock_gettime(CLOCK_REALTIME, &now);
        gmtime_r(&now.tv_sec, &tm);
        strftime(buf, bufsize, "%Y-%m-%dT%H:%M:%S.", &tm);
        sprintf(buf, "%s%09luZ", buf, now.tv_nsec);
        return retval;
}

In the lates TS you can do like this:

const isMyInterface = (val: any): val is MyInterface => {
  if (!val) { return false; }
  if (!val.myProp) { return false; }
  return true;
};

And than user like this:

if (isMyInterface(data)) {
 // now data will be type of MyInterface
}

All above answers are good. But if you have created "folders" for your jobs, things are slightly different.

Click on the folder under which you want to create a new job. Then click "New Item" on the left menu. Now your "new job" URL will look like this (assuming you are creating the new job under "my-folder"):

http://my-jenkins:8080/job/my-folder/newJob

Under Enter an item name, enter your desired new job name. Then use the Copy from text box at the bottom. Enter job path of he source job.

E.g. If your source job is under folder src-folder and name of the job is src-job, you will have to enter src-folder/src-job in "Copy from" box.

Hope it helps.

In my experience it's best to put as much code as you can into well-named modules, and only put as much code as you need to into the actual worksheet objects.

Example: Any code that uses worksheet events like Worksheet_SelectionChange or Worksheet_Calculate.

You have to use the android:hint attribute

<EditText
android:id="@+id/message"
android:hint="<<Your placeholder>>"
/>

In Android Studio, you can switch from XML -> Design View and click on the Component in the layout, the EditText field in this case. This will show all the applicable attributes for that GUI component. This will be handy when you don't know about all the attributes that are there.

You would be surprised to see that EditText has more than 140 attributes for customization.

Try this:

div.topmenu-design ul
{
  display:block;
  width:600px; /* or whatever width value */
  margin:0px auto;
}

Try numpy.array_split.

From the documentation:

>>> x = np.arange(8.0)
>>> np.array_split(x, 3)
    [array([ 0.,  1.,  2.]), array([ 3.,  4.,  5.]), array([ 6.,  7.])]

Identical to numpy.split, but won't raise an exception if the groups aren't equal length.

If number of chunks > len(array) you get blank arrays nested inside, to address that - if your split array is saved in a, then you can remove empty arrays by:

[x for x in a if x.size > 0]

Just save that back in a if you wish.

Add | select FullName to the end of your line above. If you need to actually do something with that afterwards, you might have to pipe it into a foreach loop, like so:

get-childitem "C:\windows\System32" -recurse | where {$_.extension -eq ".txt"} | % {
     Write-Host $_.FullName
}

I want to remove the "(", ")", and "-" characters from the string.

You can use the std::remove_if() algorithm to remove only the characters you specify:

#include <iostream>
#include <algorithm>
#include <string>

bool IsParenthesesOrDash(char c)
{
    switch(c)
    {
    case '(':
    case ')':
    case '-':
        return true;
    default:
        return false;
    }
}

int main()
{
    std::string str("(555) 555-5555");
    str.erase(std::remove_if(str.begin(), str.end(), &IsParenthesesOrDash), str.end());
    std::cout << str << std::endl; // Expected output: 555 5555555
}

The std::remove_if() algorithm requires something called a predicate, which can be a function pointer like the snippet above.

You can also pass a function object (an object that overloads the function call () operator). This allows us to create an even more general solution:

#include <iostream>
#include <algorithm>
#include <string>

class IsChars
{
public:
    IsChars(const char* charsToRemove) : chars(charsToRemove) {};

    bool operator()(char c)
    {
        for(const char* testChar = chars; *testChar != 0; ++testChar)
        {
            if(*testChar == c) { return true; }
        }
        return false;
    }

private:
    const char* chars;
};

int main()
{
    std::string str("(555) 555-5555");
    str.erase(std::remove_if(str.begin(), str.end(), IsChars("()- ")), str.end());
    std::cout << str << std::endl; // Expected output: 5555555555
}

You can specify what characters to remove with the "()- " string. In the example above I added a space so that spaces are removed as well as parentheses and dashes.

git log --reflog

The problem:

Microsoft Office 2010 products (or later) install updates that break compatibility of MSCOMCTL.ocx and COMCTL32.ocx. Unfortunately this affects many other programs such Visual Basic 6 SP6 and even Oracle Virtual Box v5.

The solution assumes you have not damaged your registry by deleting, replacing and re-registering MSCOMCTL.ocx and COMCTL32.ocx without unregistering the Office patch files.

Create a batch file called fix.cmd and place the following commands in it:

regsvr32 /s /u %windir%\SysWOW64\comctl32.ocx
regsvr32 /s /u %windir%\SysWOW64\mscomctl.ocx
del /y %windir%\SysWOW64\comctl32.ocx
del /y %windir%\SysWOW64\mscomctl.ocx
msiexec /passive /norestart /i KB2708437.msi
msiexec /passive /a KB2708437.msi
regtlib %windir%\SysWOW64\msdatsrc.tlb

Download from Security update for Visual Basic 6.0 Service Pack 6: August 14, 2012 the msi file and rename it to KB2708437.msi.

Note: A direct link to the Service Pack 6 download is located HERE.

Run fix.cmd and the problem will be fixed!

What fix.cmd does is to properly unregister and then delete the current MSCOMCTL.ocx and COMCTL32.ocx files, and then apply the latest Visual Basic 6 SP6 rollup patch. In fact, the script enforces the patch to be installed and then re-installed by updating every file, regardless of version. Finally it registers msdatsrc.tlb type library.

Please let me know if this works for you.

======================================================================

Advanced Solution:

If however you have accidentally damaged your registry, you need to get as many versions of MSCOMCTL.ocx and COMCTL32.ocx you can find. Then you need to start from the newer version going back to the older and register and unregister the ocx files.

The latest version of MSCOMCTL.ocx is 6.1.98.39 (v2.1) of May 2012 which is more likely the one installed on your system and causing all your problems.

The oldest (legacy) version is that shipped with Visual Basic 6 on 1998 6.1.97.82 (v2.0), or the one shipped with an early service pack 6.1.97.86 on April 2005.

Example:

regsvr32 /s comctl32.6.0.98.34.ocx
regsvr32 /s /u comctl32.6.0.98.34.ocx

regsvr32 /s comctl32.6.0.81.6.ocx
regsvr32 /s /u comctl32.6.0.81.6.ocx 

regsvr32 /s comctl32.6.0.81.5.ocx
regsvr32 /s /u comctl32.6.0.81.5.ocx

regsvr32 /s mscomctl.6.1.98.39.(2.1).ocx
regsvr32 /s /u mscomctl.6.1.98.39.(2.1).ocx

regsvr32 /s mscomctl.6.1.98.34.ocx
regsvr32 /s /u mscomctl.6.1.98.34.ocx

regsvr32 /s mscomctl.6.1.97.86.ocx
regsvr32 /s /u mscomctl.6.1.97.86.ocx

regsvr32 /s mscomctl.6.1.97.82.(2.0).ocx
regsvr32 /s /u mscomctl.6.1.97.82.(2.0).ocx

regsvr32 /s /u %windir%\SysWOW64\comctl32.ocx
regsvr32 /s /u %windir%\SysWOW64\mscomctl.ocx

del /q %windir%\SysWOW64\comctl32.ocx
del /q %windir%\SysWOW64\mscomctl.ocx

msiexec /passive /norestart /i KB2708437.msi
msiexec /passive /a KB2708437.msi

regtlib %windir%\SysWOW64\msdatsrc.tlb   

WARNING:

Do not search the internet for those files. To find different version of the OCX files download and extract official Microsoft Installer packages such as the following:

2005 Apr - Microsoft KB896559

2008 Dec - Microsoft KB926857

2009 Apr - Microsoft KB957924

It is also recommended to run CCleaner version 4.0 or later to fix any other ActiveX related problems on your computer.

Enabled Blaze and it still doesn't work?

Most probably you need to set .env from the right path, require('dotenv').config({ path: __dirname + './../.env' }); won't work (or any other path). Simply put the .env file in the functions directory, from which you deploy to Firebase.

You can set the DateTime to Nullable. By default DateTime is not nullable. You can make it nullable in a couple of ways. Using a question mark after the type DateTime? myTime or using the generic style Nullable.

DateTime? nullDate = null;

or

DateTime? nullDate;

You can also make use of array#forEach() method like this:

const cars = [{ make: 'audi', model: 'r8', year: '2012' }, { make: 'audi', model: 'rs5', year: '2013' }, { make: 'ford', model: 'mustang', year: '2012' }, { make: 'ford', model: 'fusion', year: '2015' }, { make: 'kia', model: 'optima', year: '2012' }];_x000D_
_x000D_
let newcars = {}_x000D_
_x000D_
cars.forEach(car => {_x000D_
  newcars[car.make] ? // check if that array exists or not in newcars object_x000D_
    newcars[car.make].push({model: car.model, year: car.year})  // just push_x000D_
   : (newcars[car.make] = [], newcars[car.make].push({model: car.model, year: car.year})) // create a new array and push_x000D_
})_x000D_
_x000D_
console.log(newcars);

I tried all of these things and none of them worked. I ended up having to do a couple of these things are the same time. Very frustrating that it took this much time.

The problem I had was related to running my unit tests following the upgrade to AS 3.1.

Here is what I did... 1.) Run / Edit Configurations / Select Tests.... 2.) Add options to "Gradle-aware Make" 3.) Select check box "Skip installation if ADK has not changed" on Misc tab

Good luck.

John Woo's answer is correct, as far as it goes. Here are a few additional points.

A primary key is always one of the candidate keys. Fairly often, it's the only candidate.

A table with no candidate keys does not represent a relation. If you're using the relational model to help you build a good database, then every table you design will have at least one candidate key.

The relational model would be complete without the concept of primary key. It wasn't in the original presentation of the relational model. As a practical matter, the use of foreign key references without a declared primary key leads to a mess. It could be a logically correct mess, but it's a mess nonetheless. Declaring a primary key lets the DBMS help you enforce the data rules. Most of the time, having the DBMS help you enforce the data rules is a good thing, and well worth the cost.

Some database designers and some users have some mental confusion about whether the primary key identifies a row (record) in a table or an instance of an entity in the subject matter that the table represents. In an ideal world, it's supposed to do both, and there should be a one-for-one correspondence between rows in an entity table and instances of the corresponding entity.

In the real world, things get screwed up. Somebody enters the same new employee twice, and the employee ends up with two ids. Somebody gets hired, but the data entry slips through the cracks in some manual process, and the employee doesn't get an id, until the omission is corrected. A database that does not collapse the first time things get screwed up is more robust than one that does.

If you can afford working via the file data, you can do

find -mmin +14400 -delete

Try this.

It boils down to adding android:stretchColumns="*" to your TableLayout root and setting android:layout_width="0dp" to all the children in your TableRows.

<TableLayout
    android:stretchColumns="*"   // Optionally use numbered list "0,1,2,3,..."
>
    <TableRow
        android:layout_width="0dp"
    >

You've already got it: A if test else B is a valid Python expression. The only problem with your dict comprehension as shown is that the place for an expression in a dict comprehension must have two expressions, separated by a colon:

{ (some_key if condition else default_key):(something_if_true if condition
          else something_if_false) for key, value in dict_.items() }

The final if clause acts as a filter, which is different from having the conditional expression.

None of these solutions worked for me.

Instead, I elaborate on @Martin v. Löwis 's mention of setting a config file for SSH.

SSH will look for the user's ~/.ssh/config file. I have mine setup as:

Host gitserv
    Hostname remote.server.com
    IdentityFile ~/.ssh/id_rsa.github
    IdentitiesOnly yes # see NOTES below

And I add a remote git repository:

git remote add origin git@gitserv:myrepo.git

And then git commands work normally for me.

git push -v origin master

NOTES

• The IdentitiesOnly yes is required to prevent the SSH default behavior of sending the identity file matching the default filename for each protocol. If you have a file named ~/.ssh/id_rsa that will get tried BEFORE your ~/.ssh/id_rsa.github without this option.

If you are using a map() operator on your response,you could maybe chain a toArray() operator to it...then you should be able to iterate through newly created array...at least that worked for me :)

Floats are used to store a wider range of number than can be fit in an integer. These include decimal numbers and scientific notation style numbers that can be bigger values than can fit in 32 bits. Here's the deep dive into them: http://en.wikipedia.org/wiki/Floating_point

Call visudo and add this:

user1 ALL=(user2) NOPASSWD: /home/user2/bin/test.sh

The command paths must be absolute! Then call sudo -u user2 /home/user2/bin/test.sh from a user1 shell. Done.

I wrote a function wrapper called bar() for barplot() to do what you are trying to do here, since I need to do similar things frequently. The Github link to the function is here. After copying and pasting it into R, you do

bar(dv = Species, 
    factors = c(Category, Reason), 
    dataframe = Reasonstats, 
    errbar = FALSE, 
    ylim=c(0, 140))  #I increased the upper y-limit to accommodate the legend. 

The one convenience is that it will put a legend on the plot using the names of the levels in your categorical variable (e.g., "Decline" and "Improved"). If each of your levels has multiple observations, it can also plot the error bars (which does not apply here, hence errbar=FALSE

This code is work to insert a link item right after the last existing child to inlining a small css file

var raf, cb=function(){
    //create newnode
    var link=document.createElement('link');
    link.rel='stylesheet';link.type='text/css';link.href='css/style.css';

    //insert after the lastnode
    var nodes=document.getElementsByTagName('link'); //existing nodes
    var lastnode=document.getElementsByTagName('link')[nodes.length-1]; 
    lastnode.parentNode.insertBefore(link, lastnode.nextSibling);
};

//check before insert
try {
    raf=requestAnimationFrame||
        mozRequestAnimationFrame||
        webkitRequestAnimationFrame||
        msRequestAnimationFrame;
}
catch(err){
    raf=false;
}

if (raf)raf(cb); else window.addEventListener('load',cb);

For z-index to work, you also need to give it a position:

header {
    width: 100%;
    height: 100px;
    background: url(../img/top.png) repeat-x;
    z-index: 110;
    position: relative;
}
