This is an issue in the Chrome family and has been there forever.

A bug has been raised https://bugs.chromium.org/p/chromium/issues/detail?id=904208

It can be shown here: https://codepen.io/anon/pen/Jedvwj as soon as you add a border to anything button-like (say role="button" has been added to a tag for example) Chrome messes up and sets the focus state when you click with your mouse. You should see that outline only on keyboard tab-press.

I highly recommend using this fix: https://github.com/wicg/focus-visible.

Just do the following

npm install --save focus-visible

Add the script to your html:

<script src="/node_modules/focus-visible/dist/focus-visible.min.js"></script>

or import into your main entry file if using webpack or something similar:

import 'focus-visible/dist/focus-visible.min';

then put this in your css file:

// hide the focus indicator if element receives focus via mouse, but show on keyboard focus (on tab).
.js-focus-visible :focus:not(.focus-visible) {
  outline: none;
}

// Define a strong focus indicator for keyboard focus.
// If you skip this then the browser's default focus indicator will display instead
// ideally use outline property for those users using windows high contrast mode
.js-focus-visible .focus-visible {
  outline: magenta auto 5px;
}

You can just set:

button:focus {outline:0;}

but if you have a large number of users, you're disadvantaging those who cannot use mice or those who just want to use their keyboard for speed.

To change the text;

multipleLine.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            MainActivity.myArray.set(pickId,String.valueOf(s));
            MainActivity.myAdapt.notifyDataSetChanged();
        }

        @Override
        public void afterTextChanged(Editable s) {

        }

There are multiple ways to do this in particular with Python 3.0 and above

Approach 1

This is simple approach but not recommended because you would not know exactly which line of code is actually throwing the exception:

def bad_method():
    try:
        sqrt = 0**-1
    except Exception as e:
        print(e)

bad_method()

Approach 2

This approach is recommended because it provides more detail about each exception. It includes:

• Line number for your code
• File name
• The actual error in more verbose way

The only drawback is tracback needs to be imported.

import traceback

def bad_method():
    try:
        sqrt = 0**-1
    except Exception:
        print(traceback.print_exc())

bad_method()

You can use the following command to rename the column of any table in SQL Server:

exec sp_rename 'TableName.OldColumnName', 'New colunmName'

[contains(text(),'')] only returns true or false. It won't return any element results.

SELECT * from Product_sales where
(From_date BETWEEN '2013-01-03'AND '2013-01-09') OR 
(To_date BETWEEN '2013-01-03' AND '2013-01-09') OR 
(From_date <= '2013-01-03' AND To_date >= '2013-01-09')

You have to cover all possibilities. From_Date or To_Date could be between your date range or the record dates could cover the whole range.

If one of From_date or To_date is between the dates, or From_date is less than start date and To_date is greater than the end date; then this row should be returned.

according to JAVA documentation, the JDK should be installed in this path:

/Library/Java/JavaVirtualMachines/jdkmajor.minor.macro[_update].jdk

See the uninstall JDK part at https://docs.oracle.com/javase/8/docs/technotes/guides/install/mac_jdk.html

So if you can find such folder then the JDK is installed

Here's an approach that doesn't require the brute-force 'ignore' which would only work if there was a key violation. This way works based on any conditions you specify in the update.

Try this...

-- Try to update any existing row
UPDATE players
SET age=32
WHERE user_name='steven';

-- If no update happened (i.e. the row didn't exist) then insert one
INSERT INTO players (user_name, age)
SELECT 'steven', 32
WHERE (Select Changes() = 0);

How It Works

The 'magic sauce' here is using Changes() in the Where clause. Changes() represents the number of rows affected by the last operation, which in this case is the update.

In the above example, if there are no changes from the update (i.e. the record doesn't exist) then Changes() = 0 so the Where clause in the Insert statement evaluates to true and a new row is inserted with the specified data.

If the Update did update an existing row, then Changes() = 1 (or more accurately, not zero if more than one row was updated), so the 'Where' clause in the Insert now evaluates to false and thus no insert will take place.

The beauty of this is there's no brute-force needed, nor unnecessarily deleting, then re-inserting data which may result in messing up downstream keys in foreign-key relationships.

Additionally, since it's just a standard Where clause, it can be based on anything you define, not just key violations. Likewise, you can use Changes() in combination with anything else you want/need anywhere expressions are allowed.

You have to fetch the whole data in the list and then do the iteration as it is a file and will become inefficient otherwise.

private static final Type REVIEW_TYPE = new TypeToken<List<Review>>() {
}.getType();
Gson gson = new Gson();
JsonReader reader = new JsonReader(new FileReader(filename));
List<Review> data = gson.fromJson(reader, REVIEW_TYPE); // contains the whole reviews list
data.toScreen(); // prints to screen some values

I'll throw in my two cents for relative beginners or whatnot wanting a simple spl_autoload_register() setup without all the theory: Just create one php file for each class, name that php file the same as your class name, and keep your class files in the same directory as your php file in question, then this will work:

spl_autoload_register(function ($class_name) {
    require_once dirname(__FILE__) . DIRECTORY_SEPARATOR . $class_name . '.php';
});

Googling the pieces inside this function should answer how it works. PS: I use Linux, and this works on Linux. Windows folks should test it out first.

You can use undocumented method android.app.ActivityThread.currentPackageName() :

Class<?> clazz = Class.forName("android.app.ActivityThread");
Method method  = clazz.getDeclaredMethod("currentPackageName", null);
String appPackageName = (String) method.invoke(clazz, null);

Caveat: This must be done on the main thread of the application.

Thanks to this blog post for the idea: http://blog.javia.org/static-the-android-application-package/ .

There isn't any need to write this much. Just put your desired field separator with the -F option in the AWK command and the column number you want to print segregated as per your mentioned field separator.

echo "1: " | awk -F: '{print $1}'
1

echo "1#2" | awk -F# '{print $1}'
1

base64 encode/decode example:

import base64

mystr = 'O João mordeu o cão!'

# Encode
mystr_encoded = base64.b64encode(mystr.encode('utf-8'))
# b'TyBKb8OjbyBtb3JkZXUgbyBjw6NvIQ=='

# Decode
mystr_encoded = base64.b64decode(mystr_encoded).decode('utf-8')
# 'O João mordeu o cão!'

Moreover, to convert whatever you want, you can use the QVariant class.

for example:

std::string str("hello !");
qDebug() << QVariant(str.c_str()).toString();
int test = 10;
double titi = 5.42;
qDebug() << QVariant(test).toString();
qDebug() << QVariant(titi).toString();
qDebug() << QVariant(titi).toInt();

output

"hello !"
"10"
"5.42"
5

Simply paste the following code in your web.config file.

Noted that, you have to paste the following code under <system.webServer> tag

    <httpProtocol>  
    <customHeaders>  
     <add name="Access-Control-Allow-Origin" value="*" />  
     <add name="Access-Control-Allow-Headers" value="Content-Type" />  
     <add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />  
    </customHeaders>  
  </httpProtocol>  

In Visual Studio 2017 Spanish version.

"Depurar" -> "Ventanas" -> "Configuración de Excepciones"

and search "ContextSwitchDeadlock". Then, uncheck it. Or shortcut

Ctrl+D,E

Best.

If you are looking for a programmatical modal creation, you might love this:

Even though Bootstrap's modal provides a javascript way for modal creation, you still need to write modal's html markups first.

ManyToManyField isn`t a good choice.You can use some snippets to implement MultipleChoiceField.You can be inspired by MultiSelectField with comma separated values (Field + FormField) But it has some bug in it.And you can install django-multiselectfield.This is more prefect.

You can simply check out a new branch, and then commit:

git checkout -b my_new_branch
git commit

Checking out the new branch will not discard your changes.

Here is a complete list of steps - you may not need steps 1-3 but am including them for completeness:-

1. Download VS Code and Apache Maven and install both.
2. Install the Visual Studio extension pack for Java - e.g. by pasting this URL into a web browser: vscode:extension/vscjava.vscode-java-pack and then clicking on the green Install button after it opens in VS Code.
3. NOTE: See the comment from ADTC for an "Easier GUI version of step 3...(Skip step 4)." If necessary, the Maven quick start archetype could be used to generate a new Maven project in an appropriate local folder: mvn archetype:generate -DgroupId=com.companyname.appname-DartifactId=appname-DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false. This will create an appname folder with Maven's Standard Directory Layout (i.e. src/main/java/com/companyname/appname and src/main/test/com/companyname/appname to begin with and a sample "Hello World!" Java file named appname.java and associated unit test named appnameTest.java).*
4. Open the Maven project folder in VS Code via File menu -> Open Folder... and select the appname folder.
5. Open the Command Palette (via the View menu or by right-clicking) and type in and select Tasks: Configure task then select Create tasks.json from template.

6. Choose maven ("Executes common Maven commands"). This creates a tasks.json file with "verify" and "test" tasks. More can be added corresponding to other Maven Build Lifecycle phases. To specifically address your requirement for classes to be built without a JAR file, a "compile" task would need to be added as follows:

   {
       "label": "compile",
       "type": "shell",
       "command": "mvn -B compile",
       "group": "build"
   },
   

7. Save the above changes and then open the Command Palette and select "Tasks: Run Build Task" then pick "compile" and then "Continue without scanning the task output". This invokes Maven, which creates a target folder at the same level as the src folder with the compiled class files in the target\classes folder.

Addendum: How to run/debug a class

Following a question in the comments, here are some steps for running/debugging:-

1. Show the Debug view if it is not already shown (via View menu - Debug or CtrlShiftD).
2. Click on the green arrow in the Debug view and select "Java".
3. Assuming it hasn't already been created, a message "launch.json is needed to start the debugger. Do you want to create it now?" will appear - select "Yes" and then select "Java" again.
4. Enter the fully qualified name of the main class (e.g. com.companyname.appname.App) in the value for "mainClass" and save the file.
5. Click on the green arrow in the Debug view again.

CREATE TABLE NEW_TABLENAME LIKE OLD_TABLENAME;

Works for DB2 V 9.7

Probably late but here is a plugin that can do the job : http://multi-level-push-menu.make.rs/

Also v2 can use mobile gesture such as swipe ;)

Try like this

ImageButton imagetrans=(ImageButton)findViewById(R.id.ImagevieID);

imagetrans.setBackgroundColor(Color.TRANSPARENT);

OR

include this in your .xml file in res/layout

android:background="@android:color/transparent 

You should only access Linux files system (those located in lxss folder) from inside WSL; DO NOT create/modify any files in lxss folder in Windows - it's dangerous and WSL will not see these files.

Files can be shared between WSL and Windows, though; put the file outside of lxss folder. You can access them via drvFS (/mnt) such as /mnt/c/Users/yourusername/files within WSL. These files stay synced between WSL and Windows.

For details and why, see: https://blogs.msdn.microsoft.com/commandline/2016/11/17/do-not-change-linux-files-using-windows-apps-and-tools/

It should be:

req.url

express 3.1.x

You can use the following code inside the style tag:

@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {  
/* IE10+ specific styles go here */  
}

Below is an example that worked for me:

<style type="text/css">

@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {  
   /* IE10+ specific styles go here */  
   #flashvideo {
        width:320px;
        height:240;
        margin:-240px 0 0 350px;
        float:left;
    }

    #googleMap {
        width:320px;
        height:240;
        margin:-515px 0 0 350px;
        float:left;
        border-color:#000000;
    }
}

#nav li {
    list-style:none;
    width:240px;
    height:25px;
    }

#nav a {
    display:block;
    text-indent:-5000px;
    height:25px;
    width:240px;
    }
</style>

Please note that since (#nav li) and (#nav a) are outside of the @media screen ..., they are general styles.

Using an array would be a little more efficient than creating a list.

@Html.DropDownListFor(x => x.Tipo, new SelectListItem[]{
                new SelectListItem() {Text = "Exemplo1", Value="Exemplo1"},
                new SelectListItem() {Text = "Exemplo2", Value="Exemplo2"},
                new SelectListItem() {Text = "Exemplo3", Value="Exemplo3"}})

As usual, VBScript is available for you to use.....

Set objFS = CreateObject("Scripting.FileSystemObject")
Set wshArgs = WScript.Arguments
strFile = wshArgs(0)
WScript.Echo objFS.GetFile(strFile).Size & " bytes"

Save as filesize.vbs and enter on the command-line:

C:\test>cscript /nologo filesize.vbs file.txt
79 bytes

Use a for loop (in batch) to get the return result.

in the office doc: https://developer.android.com/reference/android/support/constraint/ConstraintLayout

When a dimension is set to MATCH_CONSTRAINT, the default behavior is to have the resulting size take all the available space.

Using 0dp, which is the equivalent of "MATCH_CONSTRAINT"

Important: MATCH_PARENT is not recommended for widgets contained in a ConstraintLayout. Similar behavior can be defined by using MATCH_CONSTRAINT with the corresponding left/right or top/bottom constraints being set to "parent"

In addition to what John Skeet said, here's an overview of the Java 7 project. It includes a list and description of the features.

Note: JDK 7 was released on July 28, 2011, so you should now go to the official java SE site.

To make life easier when entering multiple dates/times it is possible to use a custom format to remove the need to enter the colon, and the leading "hour" 0. This however requires a second field for the numerical date to be stored, as the displayed date from the custom format is in base 10.

Displaying a number as a time (no need to enter colons, but no time conversion)

For displaying the times on the sheet, and for entering them without having to type the colon set the cell format to custom and use:

0/:00

Then enter your time. For example, if you wanted to enter 62:30, then you would simply type 6230 and your custom format would visually insert a colon 2 decimal points from the right.

If you only need to display the times, stop here.

Converting number to time

If you need to be able to calculate with the times, you will need to convert them from base 10 into the time format.

This can be done with the following formula (change A2 to the relevant cell reference):

=TIME(0,TRUNC(A2/100),MOD(A2,100))

• =TIME starts the number to time conversion
• We don't need hours, so enter 0, at the beginning of the formula, as the format is always hh,mm,ss (to display hours and minutes instead of minutes and seconds, place the 0 at the end of the formula).
• For the minutes, TRUNC(A2/100), discards the rightmost 2 digits.
• For the seconds, MOD(A2,100) keeps the rightmost 2 digits and discards everything to the left.

The above formula was found and adapted from this article: PC Mag.com - Easy Date and Time Entry in Excel

Alternatively, you could skip the 0/:00 custom formatting, and just enter your time in a cell to be referenced of the edge of the visible workspace or on another sheet as you would for the custom formatting (ie: 6230 for 62:30)

Then change the display format of the cells with the formula to [m]:ss as @Sean Chessire suggested.

Here is a screen shot to show what I mean.

There are now multiple ways to mimic this same effect but further tailor the properties based on the use case. As stated above, this works:

.product__specfield_8_arrow { display: inline-block } 

but also

.product__specfield_8_arrow { display: inline-flex } // flex container will be inline
.product__specfield_8_arrow { display: inline-grid } // grid container will be inline
.product__specfield_8_arrow { display: inline-table } // table will be inline-level table

This JSFiddle shows how similar these display properties are in this case.

For a relevant discussion please see this SO post.

There is equally formatDate

const format = 'dd/MM/yyyy';
const myDate = '2019-06-29';
const locale = 'en-US';
const formattedDate = formatDate(myDate, format, locale);

According to the API it takes as param either a date string, a Date object, or a timestamp.

Gotcha: Out of the box, only en-US is supported.

If you need to add another locale, you need to add it and register it in you app.module, for example for Spanish:

import { registerLocaleData } from '@angular/common';
import localeES from "@angular/common/locales/es";
registerLocaleData(localeES, "es");

Don't forget to add corresponding import:

import { formatDate } from "@angular/common";

and with --outdated as an extra argument, you will get the Current and Latest versions of the packages you are using :

$ pip list --outdated
distribute (Current: 0.6.34 Latest: 0.7.3)
django-bootstrap3 (Current: 1.1.0 Latest: 4.3.0)
Django (Current: 1.5.4 Latest: 1.6.4)
Jinja2 (Current: 2.6 Latest: 2.8)

So combining with AdamKG 's answer :

$ pip list --outdated | grep Jinja2
Jinja2 (Current: 2.6 Latest: 2.8)

Check pip-tools too : https://github.com/nvie/pip-tools

Best thing is to try it for yourself.

mkdir test
cd test
git init
touch aaa.txt
git add .
git commit -a -m "New file"
mv aaa.txt bbb.txt
git add .
git status
git commit --dry-run -a

Now git status and git commit --dry-run -a shows two different results where git status shows bbb.txt as a new file/ aaa.txt is deleted, and the --dry-run commands shows the actual rename.

~/test$ git status

# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   new file:   bbb.txt
#
# Changes not staged for commit:
#   (use "git add/rm <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#   deleted:    aaa.txt
#


/test$ git commit --dry-run -a

# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   renamed:    aaa.txt -> bbb.txt
#

Now go ahead and do the check-in.

git commit -a -m "Rename"

Now you can see that the file is in fact renamed, and what's shown in git status is wrong.

Moral of the story: If you're not sure whether your file got renamed, issue a "git commit --dry-run -a". If its showing that the file is renamed, you're good to go.

var junk=new Array();
junk.push('This is a string.');

Et cetera.

Enums don't just have to represent passive sets (e.g. colours). They can represent more complex objects with functionality, and so you're then likely to want to add further functionality to these - e.g. you may have interfaces such as Printable, Reportable etc. and components that support these.

Are you sure that your address is 168.192.1.2 and not 192.168.1.2?

Notice the swapped first two numbers.

Try this worked for me Add this dependency to your build.gradle File

compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'

OK, the following answer is slightly beyond-scope if you only care about Python 3, but this question is the first Google hit even if you don't specify the Python version, so here's a way that works on both Python 2 and Python 3.

I'm also interpreting the question to be about converting bytes to the str type: that is, bytes-y on Python 2, and Unicode-y on Python 3.

Given that, the best approach I know is:

import six

bytes_to_hex_str = lambda b: ' '.join('%02x' % i for i in six.iterbytes(b))

The following assertion will be true for either Python 2 or Python 3, assuming you haven't activated the unicode_literals future in Python 2:

assert bytes_to_hex_str(b'jkl') == '6a 6b 6c'

(Or you can use ''.join() to omit the space between the bytes, etc.)

Rather than encrypt/decrypt, you should be passing the password through a hashing algorithm, md5/sha512, or similar. What you would ideally do is hash the password and store the hash, then when the password is needed, you hash the entry and compare the entries. A password will then never be "decrypted", simply hashed and then compared.

Had this problem where the Deployment was in a sub-chart and the values controlling it were in the parent chart's values file. This is what we used to trigger restart:

spec:
  template:
    metadata:
      annotations:
        checksum/config: {{ tpl (toYaml .Values) . | sha256sum }}

Obviously this will trigger restart on any value change but it works for our situation. What was originally in the child chart would only work if the config.yaml in the child chart itself changed:

    checksum/config: {{ include (print $.Template.BasePath "/config.yaml") . | sha256sum }}

Adding the following to build.gradle solves the problem :

android {
 ...
compileOptions.encoding = 'ISO-8859-1'
 }

Its not very elegant but in case you cant change the creation of dictionary, and all you need is a dirty hack, how about this:

var item = MyDictionary.Where(x => x.Key.ToLower() == MyIndex.ToLower()).FirstOrDefault();
    if (item != null)
    {
        TheValue = item.Value;
    }

This is no longer up-to-date!

Push.default is unset; its implicit value has changed in
Git 2.0 from 'matching' to 'simple'. To squelch this message
and maintain the traditional behavior, use:

  git config --global push.default matching

To squelch this message and adopt the new behavior now, use:

  git config --global push.default simple

When push.default is set to 'matching', git will push local branches
to the remote branches that already exist with the same name.

Since Git 2.0, Git defaults to the more conservative 'simple'
behavior, which only pushes the current branch to the corresponding
remote branch that 'git pull' uses to update the current branch.

Just check my scripts it's working well:

  function handleFileSelect(evt) {
    var files = evt.target.files; // FileList object

    // Loop through the FileList and render image files as thumbnails.
    for (var i = 0, f; f = files[i]; i++) {

      // Only process image files.
      if (!f.type.match('image.*')) {
        continue;
      }

      var reader = new FileReader();

      // Closure to capture the file information.
      reader.onload = (function(theFile) {
        return function(e) {
          // Render thumbnail.
          var span = document.createElement('span');
          span.innerHTML = ['<img class="thumb" src="', e.target.result,
                            '" title="', escape(theFile.name), '"/>'].join('');
          document.getElementById('list').insertBefore(span, null);
        };
      })(f);

      // Read in the image file as a data URL.
      reader.readAsDataURL(f);
    }
  }

  document.getElementById('files').addEventListener('change', handleFileSelect, false);

#list img{
  width: auto;
  height: 100px;
  margin: 10px ;
}

# remove all old versions of the gem
gem cleanup rjb

# choose which ones you want to remove
gem uninstall rjb

# remove version 1.1.9 only
gem uninstall rjb --version 1.1.9

# remove all versions less than 1.3.4
gem uninstall rjb --version '<1.3.4'

Use overflow-y:auto for displaying scroll automatically when the content exceeds the divs set height.

See this demo

The authenticity token is used to prevent Cross-Site Request Forgery attacks (CSRF). To understand the authenticity token, you must first understand CSRF attacks.

CSRF

Suppose that you are the author of bank.com. You have a form on your site that is used to transfer money to a different account with a GET request:

A hacker could just send an HTTP request to the server saying GET /transfer?amount=$1000000&account-to=999999, right?

Wrong. The hackers attack won't work. The server will basically think?

Huh? Who is this guy trying to initiate a transfer. It's not the owner of the account, that's for sure.

How does the server know this? Because there's no session_id cookie authenticating the requester.

When you sign in with your username and password, the server sets a session_id cookie on your browser. That way, you don't have to authenticate each request with your username and password. When your browser sends the session_id cookie, the server knows:

Oh, that's John Doe. He signed in successfully 2.5 minutes ago. He's good to go.

A hacker might think:

Hmm. A normal HTTP request won't work, but if I could get my hand on that session_id cookie, I'd be golden.

The users browser has a bunch of cookies set for the bank.com domain. Every time the user makes a request to the bank.com domain, all of the cookies get sent along. Including the session_id cookie.

So if a hacker could get you to make the GET request that transfers money into his account, he'd be successful. How could he trick you into doing so? With Cross Site Request Forgery.

It's pretty simply, actually. The hacker could just get you to visit his website. On his website, he could have the following image tag:

<img src="http://bank.com/transfer?amount=$1000000&account-to=999999">

When the users browser comes across that image tag, it'll be making a GET request to that url. And since the request comes from his browser, it'll send with it all of the cookies associated with bank.com. If the user had recently signed in to bank.com... the session_id cookie will be set, and the server will think that the user meant to transfer $1,000,000 to account 999999!

Well, just don't visit dangerous sites and you'll be fine.

That isn't enough. What if someone posts that image to Facebook and it appears on your wall? What if it's injected into a site you're visiting with a XSS attack?

It's not so bad. Only GET requests are vulnerable.

Not true. A form that sends a POST request can be dynamically generated. Here's the example from the Rails Guide on Security:

<a href="http://www.harmless.com/" onclick="
  var f = document.createElement('form');
  f.style.display = 'none';
  this.parentNode.appendChild(f);
  f.method = 'POST';
  f.action = 'http://www.example.com/account/destroy';
  f.submit();
  return false;">To the harmless survey</a>

Authenticity Token

When your ApplicationController has this:

protect_from_forgery with: :exception

This:

<%= form_tag do %>
  Form contents
<% end %>

Is compiled into this:

<form accept-charset="UTF-8" action="/" method="post">
  <input name="utf8" type="hidden" value="&#x2713;" />
  <input name="authenticity_token" type="hidden" value="J7CBxfHalt49OSHp27hblqK20c9PgwJ108nDHX/8Cts=" />
  Form contents
</form>

In particular, the following is generated:

<input name="authenticity_token" type="hidden" value="J7CBxfHalt49OSHp27hblqK20c9PgwJ108nDHX/8Cts=" />

To protect against CSRF attacks, if Rails doesn't see the authenticity token sent along with a request, it won't consider the request safe.

How is an attacker supposed to know what this token is? A different value is generated randomly each time the form is generated:

A Cross Site Scripting (XSS) attack - that's how. But that's a different vulnerability for a different day.

In the above example they going to display all user and particular id details now I want to use both id and name,

1) localhost:8093/plejson/shop/user <---this link will display all user details
2) localhost:8093/plejson/shop/user/11 <----if i use 11 in link means, it will display particular user 11 details

now I want to use both id and name

localhost:8093/plejson/shop/user/11/raju <-----------------like this it means we can use any one in this please help me out.....

If the function floatval does not work you can try to make this :

    $string = "2968789218";
    $float = $string * 1.0;
    echo $float;

But for me all the previous answer worked ( try it in http://writecodeonline.com/php/ ) Maybe the problem is on your server ?

If accessing/printing single element lists (e.g., sequentially or filtered):

my_list = [u'String'] # sample element
my_list = [str(my_list[0])]

If you write like this in Button tag in xml file : android:onClick="setLogin" then

Do like this:

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

<Button
    android:id="@+id/button1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btn"
    android:onClick="onClickBtn" />

</LinearLayout>

and in Code part:

public class StartUpActivity extends Activity 
{
    public void onCreate(Bundle savedInstanceState) 
    {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);    
    }

    public void onClickBtn(View v)
    {
        Toast.makeText(this, "Clicked on Button", Toast.LENGTH_LONG).show();
    } 
}

and no need all this:

 Button button = (Button) findViewById(R.id.button1);
 button.setOnClickListener(new OnClickListener() {

    public void onClick(View v) {
        // TODO Auto-generated method stub

    }
 });

Check it once;

When you say 2^8 you get 256, but the numbers in computers terms begins from the number 0. So, then you got the 255, you can probe it in a internet mask for the IP or in the IP itself.

255 is the maximum value of a 8 bit integer : 11111111 = 255

Does that help?

I don't believe the expression is sensical as it is.

Elvis means "if truthy, use the value, else use this other thing."

Your "other thing" is a closure, and the value is status != null, neither of which would seem to be what you want. If status is null, Elvis says true. If it's not, you get an extra layer of closure.

Why can't you just use:

(it.description == desc) && ((status == null) || (it.status == status))

Even if that didn't work, all you need is the closure to return the appropriate value, right? There's no need to create two separate find calls, just use an intermediate variable.

Most commands allow args to come in any order. Just move the commented flags to the end of the line:

ls -l -a /etc # -F is turned off

Then to turn it back on, just uncomment and remove the text:

ls -l -a /etc -F

I set the delegate of the UITextField to my ViewController class.

In that class I implemented this method as following:

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    [textField resignFirstResponder];
    return NO;
}

I learned from the other answers and decided to use this code throughout my site:

var query = require('url').parse(req.url,true).query;

Then you can just call

var id = query.id;
var option = query.option;

where the URL for get should be

/path/filename?id=123&option=456

Here is another idea that allow you to affect other elements without considering any specific selector and by only using the :hover state of the main element.

For this, I will rely on the use of custom properties (CSS variables). As we can read in the specification:

Custom properties are ordinary properties, so they can be declared on any element, are resolved with the normal inheritance and cascade rules ...

The idea is to define custom properties within the main element and use them to style child elements and since these properties are inherited we simply need to change them within the main element on hover.

Here is an example:

#container {_x000D_
  width: 200px;_x000D_
  height: 30px;_x000D_
  border: 1px solid var(--c);_x000D_
  --c:red;_x000D_
}_x000D_
#container:hover {_x000D_
  --c:blue;_x000D_
}_x000D_
#container > div {_x000D_
  width: 30px;_x000D_
  height: 100%;_x000D_
  background-color: var(--c);_x000D_
}

<div id="container">_x000D_
  <div>_x000D_
  </div>_x000D_
</div>

Why this can be better than using specific selector combined with hover?

I can provide at least 2 reasons that make this method a good one to consider:

1. If we have many nested elements that share the same styles, this will avoid us complex selector to target all of them on hover. Using Custom properties, we simply change the value when hovering on the parent element.
2. A custom property can be used to replace a value of any property and also a partial value of it. For example we can define a custom property for a color and we use it within a border, linear-gradient, background-color, box-shadow etc. This will avoid us reseting all these properties on hover.

Here is a more complex example:

.container {_x000D_
  --c:red;_x000D_
  width:400px;_x000D_
  display:flex;_x000D_
  border:1px solid var(--c);_x000D_
  justify-content:space-between;_x000D_
  padding:5px;_x000D_
  background:linear-gradient(var(--c),var(--c)) 0 50%/100% 3px no-repeat;_x000D_
}_x000D_
.box {_x000D_
  width:30%;_x000D_
  background:var(--c);_x000D_
  box-shadow:0px 0px 5px var(--c);_x000D_
  position:relative;_x000D_
}_x000D_
.box:before {_x000D_
  content:"A";_x000D_
  display:block;_x000D_
  width:15px;_x000D_
  margin:0 auto;_x000D_
  height:100%;_x000D_
  color:var(--c);_x000D_
  background:#fff;_x000D_
}_x000D_
_x000D_
/*Hover*/_x000D_
.container:hover {_x000D_
  --c:blue;_x000D_
}

<div class="container">_x000D_
<div class="box"></div>_x000D_
<div class="box"></div>_x000D_
</div>

As we can see above, we only need one CSS declaration in order to change many properties of different elements.

• The length of the message is unlimited.

Append Length

A 64-bit representation of b (the length of the message before the padding bits were added) is appended to the result of the previous step. In the unlikely event that b is greater than 2^64, then only the low-order 64 bits of b are used.

• The hash is always 128 bits. If you encode it as a hexdecimal string you can encode 4 bits per character, giving 32 characters.
• MD5 is not encryption. You cannot in general "decrypt" an MD5 hash to get the original string.

See more here.

You can overwrite a CSS class by making it "more specific".

You go up the HTML tree, and specify parent elements:

div.sidebar { ... } is more specific than .sidebar { ... }

You can go all the way up to BODY if you need to:

body .sidebar { ... } will override virtually anything.

See this handy guide: http://css-tricks.com/855-specifics-on-css-specificity/

As a bare minimum:

tsconfig:

 "lib": [
      "es2015"
    ]

and install a polyfill such as https://github.com/zloirock/core-js if you want IE < 11 support: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map

Recursive function example:

def recursive(string, num):
    print "#%s - %s" % (string, num)
    recursive(string, num+1)

Run it with:

recursive("Hello world", 0)

Right should do:

select RIGHT('abcdeffff',4)

I got the same use case today(31/07/2018) and found this to be a workaround. It is based on my research and it worked for me. Expectation - To achieve the following in TypeScript:

var myStaticClass = {
    property: 10,
    method: function(){} 
}

I did this:

//MyStaticMembers.ts
namespace MyStaticMembers {
        class MyStaticClass {
           static property: number = 10;
           static myMethod() {...}
        }
        export function Property(): number {
           return MyStaticClass.property;
        }
        export function Method(): void {
           return MyStaticClass.myMethod();
        }
     }

Hence we shall consume it as below:

//app.ts
/// <reference path="MyStaticMembers.ts" />
    console.log(MyStaticMembers.Property);
    MyStaticMembers.Method();

This worked for me. If anyone has other better suggestions please let us all hear it !!! Thanks...

First checkout to the branch which you want to rename:

git branch -m old_branch new_branch
git push -u origin new_branch

To remove an old branch from remote:

git push origin :old_branch

You can do something like:

function ChckbxsCtrl($scope, $filter) {
    $scope.chkbxs = [{
        label: "Led Zeppelin",
        val: false
    }, {
        label: "Electric Light Orchestra",
        val: false
    }, {
        label: "Mark Almond",
        val: false
    }];

    $scope.$watch("chkbxs", function(n, o) {
        var trues = $filter("filter")(n, {
            val: true
        });
        $scope.flag = trues.length;
    }, true);
}

And a template:

<div ng-controller="ChckbxsCtrl">
    <div ng-repeat="chk in chkbxs">
        <input type="checkbox" ng-model="chk.val" />
        <label>{{chk.label}}</label>
    </div>
    <div ng-show="flag">I'm ON when band choosed</div>
</div>

Working: http://jsfiddle.net/cherniv/JBwmA/

UPDATE: Or you can go little bit different way , without using $scope's $watch() method, like:

$scope.bandChoosed = function() {
    var trues = $filter("filter")($scope.chkbxs, {
        val: true
    });
    return trues.length;
}

And in a template do:

<div ng-show="bandChoosed()">I'm ON when band choosed</div>

Fiddle: http://jsfiddle.net/uzs4sgnp/

For loops are a bad construct for this.

Using while

var numbers = new List<int>(Enumerable.Range(1, 3));

while (numbers.Count > 0)
{
    numbers.RemoveAt(0);
}

But, if you absolutely must use for

var numbers = new List<int>(Enumerable.Range(1, 3));

for (; numbers.Count > 0;)
{
    numbers.RemoveAt(0);
}

Or, this:

public static class Extensions
{

    public static IList<T> Remove<T>(
        this IList<T> numbers,
        Func<T, bool> predicate)
    {
        numbers.ForEachBackwards(predicate, (n, index) => numbers.RemoveAt(index));
        return numbers;
    }

    public static void ForEachBackwards<T>(
        this IList<T> numbers,
        Func<T, bool> predicate,
        Action<T, int> action)
    {
        for (var i = numbers.Count - 1; i >= 0; i--)
        {
            if (predicate(numbers[i]))
            {
                action(numbers[i], i);
            }
        }
    }
}

Usage:

var numbers = new List<int>(Enumerable.Range(1, 10)).Remove((n) => n > 5);

You could use reflection and loop through all the object properties, then get their values and save them to the log. The formatting is really trivial (you could use \t to indent an objects properties and its values):

MyObject
    Property1 = value
    Property2 = value2
    OtherObject
       OtherProperty = value ...

My approach is to store the PID to a file in /tmp, and to find the right process using the -S option for ssh. That might be a misuse but works for me.

#!/bin/bash

TARGET_REDIS=${1:-redis.someserver.com}
PROXY="proxy.somewhere.com"

LOCAL_PORT=${2:-6379}

if [ "$1" == "stop" ] ; then
    kill `cat /tmp/sshTunel${LOCAL_PORT}-pid`
    exit
fi

set -x

ssh -f -i ~/.ssh/aws.pem centos@$PROXY -L $LOCAL_PORT:$TARGET_REDIS:6379 -N -S /tmp/sshTunel$LOCAL_PORT  ## AWS DocService dev, DNS alias
# SSH_PID=$! ## Only works with &
SSH_PID=`ps aux | grep sshTunel${LOCAL_PORT} | grep -v grep | awk '{print $2}'`
echo $SSH_PID > /tmp/sshTunel${LOCAL_PORT}-pid

Better approach might be to query for the SSH_PID right before killing it, since the file might be stale and it would kill a wrong process.

What I needed: A document number with a fixed number of integers that would also act like an AutoField.

My searches took me all over incl. this page.

Finally I did something like this:

I created a table with a DocuNumber field as an IntegerField with foll. attributes:

• max_length=6
• primary_key=True
• unique=True
• default=100000

The max_length value anything as required (and thus the corresponding default= value).

A warning is issued while creating the said model, which I could ignore.

Afterwards, created a document (dummy) whence as expected, the document had an integer field value of 100000.

Afterwards changed the model key field as:

• Changed the field type as: AutoField
• Got rid of the max_length And defaultattributes
• Retained the primary_key = True attribute

The next (desired document) created had the value as 100001 with subsequent numbers getting incremented by 1.

So far so good.

From a Java specification summary: http://www.cs.cornell.edu/andru/javaspec/17.doc.html

The synchronized statement (§14.17) computes a reference to an object; it then attempts to perform a lock action on that object and does not proceed further until the lock action has successfully completed. ...

A synchronized method (§8.4.3.5) automatically performs a lock action when it is invoked; its body is not executed until the lock action has successfully completed. If the method is an instance method, it locks the lock associated with the instance for which it was invoked (that is, the object that will be known as this during execution of the body of the method). If the method is static, it locks the lock associated with the Class object that represents the class in which the method is defined. ...

Based on these descriptions, I would say most previous answers are correct, and a synchronized method might be particularly useful for static methods, where you would otherwise have to figure out how to get the "Class object that represents the class in which the method was defined."

Edit: I originally thought these were quotes of the actual Java spec. Clarified that this page is just a summary/explanation of the spec

Update (2018-01-06): This answer is obsolete. Modern versions of PyCharm provide Paths via Settings ? Project Interpreter ? ? ? Show All ? Show paths button.

PyCharm Professional Edition has the Paths tab in Python Interpreters settings, but Community Edition apparently doesn't have it.

As a workaround, you can create a symlink for your imported library under your project's root.

For example:

myproject
    mypackage
        __init__.py
    third_party -> /some/other/directory/third_party

If you want to do this in jQuery instead of CSS, you basically follow the same process.

Assuming you have some <div id="target"></div>, you can use the following code:

$("#target").hover(function() {
    $(this).css('cursor','pointer');
}, function() {
    $(this).css('cursor','auto');
});

and that should do it.

Thanks to Gruff Bunny and Louis' comments, I found the source of the issue.

As I use Backbone.js too, I loaded a special build of Lodash compatible with Backbone and Underscore that disables some features. In this example:

var clone = _.clone(data, true);

data[1].values.d = 'x';

• with the Normal build: _.isEqual(data, clone) === false
• with the Underscore build: _.isEqual(data, clone) === true

I just replaced the Underscore build with the Normal build in my Backbone application and the application is still working. So I can now use the Lodash .clone with the expected behaviour.

Edit 2018: the Underscore build doesn't seem to exist anymore. If you are reading this in 2018, you could be interested by this documentation (Backbone and Lodash).

Open notepad and paste this code:

@echo off
powershell -Command "Start-Process cmd -Verb RunAs -ArgumentList '/c %*'"
@echo on

Then, save the file as sudo.cmd. Copy this file and paste it at C:\Windows\System32 or add the path where sudo.cmd is to your PATH Environment Variable.

When you open command prompt, you can now run something like sudo start ..

If you want the terminal window to stay open when you run the command, change the code in notepad to this:

@echo off
powershell -Command "Start-Process cmd -Verb RunAs -ArgumentList '/k %*'"
@echo on

Explanation:

powershell -Command runs a powershell command.

Start-Process is a powershell command that starts a process, in this case, command prompt.

-Verb RunAs runs the command as admin.

-Argument-List runs the command with arguments.

Our arguments are '/c %*'. %* means all arguments, so if you did sudo foo bar, it would run in command prompt foo bar because the parameters are foo and bar, and %* returns foo bar.

The /c is a cmd parameter for closing the window after the command is finished, and the /k is a cmd parameter for keeping the window open.

OPcache replaces APC

Because OPcache is designed to replace the APC module, it is not possible to run them in parallel in PHP. This is fine for caching PHP opcode as neither affects how you write code.

However it means that if you are currently using APC to store other data (through the apc_store() function) you will not be able to do that if you decide to use OPCache.

You will need to use another library such as either APCu or Yac which both store data in shared PHP memory, or switch to use something like memcached, which stores data in memory in a separate process to PHP.

Also, OPcache has no equivalent of the upload progress meter present in APC. Instead you should use the Session Upload Progress.

Settings for OPcache

The documentation for OPcache can be found here with all of the configuration options listed here. The recommended settings are:

; Sets how much memory to use
opcache.memory_consumption=128

;Sets how much memory should be used by OPcache for storing internal strings 
;(e.g. classnames and the files they are contained in)
opcache.interned_strings_buffer=8

; The maximum number of files OPcache will cache
opcache.max_accelerated_files=4000

;How often (in seconds) to check file timestamps for changes to the shared
;memory storage allocation.
opcache.revalidate_freq=60

;If enabled, a fast shutdown sequence is used for the accelerated code
;The fast shutdown sequence doesn't free each allocated block, but lets
;the Zend Engine Memory Manager do the work.
opcache.fast_shutdown=1

;Enables the OPcache for the CLI version of PHP.
opcache.enable_cli=1

If you use any library or code that uses code annotations you must enable save comments:

opcache.save_comments=1

If disabled, all PHPDoc comments are dropped from the code to reduce the size of the optimized code. Disabling "Doc Comments" may break some existing applications and frameworks (e.g. Doctrine, ZF2, PHPUnit)

When an <option> isn't given a value="", the text becomes its value, so you can just use .val() on the <select> to set by value, like this:

var text1 = 'Monkey';
$("#mySelect1").val(text1);

var text2 = 'Mushroom pie';
$("#mySelect2").val(text2);

You can test it out here, if the example is not what you're after and they actually have a value, use the <option> element's .text property to .filter(), like this:

var text1 = 'Monkey';
$("#mySelect1 option").filter(function() {
    return this.text == text1; 
}).attr('selected', true);

var text2 = 'Mushroom pie';
$("#mySelect2 option").filter(function() {
    return this.text == text2; 
}).attr('selected', true);?

You can test that version here.

If you are using Spring Framework with application.yml and having trouble to make the test find the SQL file on the INIT property, you can use the classpath: notation.

For example, if you have a init.sql SQL file on the src/test/resources, just use:

url=jdbc:h2:~/test;INIT=RUNSCRIPT FROM 'classpath:init.sql';DB_CLOSE_DELAY=-1;

Here is what i did on ubuntu 18.04 LTS with Jenkins 2.176.2

I created .bash_aliases file and added there path, proxy variables and so on.

In beginning of .bashrc there was this defined.

# If not running interactively, don't do anything
case $- in
    *i*) ;;
      *) return;;
esac

So it's checking that if we are start non-interactive shell then we don't do nothing here.

bottom of the .bashrc there was include for .bash_aliases

# Alias definitions.
# You may want to put all your additions into a separate file like
# ~/.bash_aliases, instead of adding them here directly.
# See /usr/share/doc/bash-doc/examples in the bash-doc package.

if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi

so i moved .bash_aliases loading first at .bashrc just above non-interactive check.

This didn't work first but then i disconnected slave and re-connected it so it's loading variables again. You don't need to restart whole jenkins if you are modifying slave variables. just disconnect and re-connect.

Wiki from Ubuntu website:

For Ubuntu 10.04 LTS, the sun-java6 packages have been dropped from the Multiverse section of the Ubuntu archive. It is recommended that you use openjdk-6 instead.

If you can not switch from the proprietary Sun JDK/JRE to OpenJDK, you can install sun-java6 packages from the Canonical Partner Repository. You can configure your system to use this repository via command-line:

 sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
 sudo apt-get update   
 sudo apt-get install sun-java6-jre sun-java6-plugin
 sudo update-alternatives --config java

For Ubuntu 10.10, the sun-java6 packages have been dropped from the Multiverse section of the Ubuntu archive. It is recommended that you use openjdk-6 instead.

If you can not switch from the proprietary Sun JDK/JRE to OpenJDK, you can install sun-java6 packages from the Canonical Partner Repository. You can configure your system to use this repository via command-line:

 sudo add-apt-repository "deb http://archive.canonical.com/ maverick partner"
 sudo apt-get update

The mail function do not guarantee the actual delivery of mail. All it do is to pass the message to external program (usually sendmail). You need a properly configured SMTP server in order for this to work. Also keep in mind it does not support SMTP authentication. You may check out the PEAR::Mail library of SwiftMailer, both of them give you more options.

Adding to the above answers:

Suppose you have a a class named "myPackage.MyClass". Assuming that is in classpath, the following statements are equivalent.

//checking class name using string comparison, only Runtime check possible
if(myInstance.getClass().getName().equals(Class.forName("myPackage.MyClass")).getName()){}

//checking actual Class object for equality, only Runtime check possible
if(myInstance.getClass().getName() == Class.forName("myPackage.MyClass"))){}

//checking actual Class object for equality, but compile time validation
//will ensure MyClass is in classpath. Hence this approach is better (according to fail-fast paradigm)
if(myInstance.getClass() == MyClass.class){}

Similarly, the following are also equivalent.

Class<?> myClassObject = MyClass.class; //compile time check

Class<?> myClassObject = Class.forname("myPackage.MyClass"); //only runtime check

If JVM loads a type, a class object representing that type will be present in JVM. we can get the metadata regarding the type from that class object which is used very much in reflection package. MyClass.class is a shorthand method which actually points to the Class object representing MyClass.

As an addendum, some information about Class<?> reference which will be useful to read along with this as most of the time, they are used together.

Class<?> reference type can hold any Class object which represents any type.

This works in a similar fashion if the Class<?> reference is in method argument as well.

Please note that the class "Class" does not have a public constructor. So you cannot instantiate "Class" instances with "new" operator.

Could not commit JPA transaction: Transaction marked as rollbackOnly

This exception occurs when you invoke nested methods/services also marked as @Transactional. JB Nizet explained the mechanism in detail. I'd like to add some scenarios when it happens as well as some ways to avoid it.

Suppose we have two Spring services: Service1 and Service2. From our program we call Service1.method1() which in turn calls Service2.method2():

class Service1 {
    @Transactional
    public void method1() {
        try {
            ...
            service2.method2();
            ...
        } catch (Exception e) {
            ...
        }
    }
}

class Service2 {
    @Transactional
    public void method2() {
        ...
        throw new SomeException();
        ...
    }
}

SomeException is unchecked (extends RuntimeException) unless stated otherwise.

Scenarios:

1. Transaction marked for rollback by exception thrown out of method2. This is our default case explained by JB Nizet.

2. Annotating method2 as @Transactional(readOnly = true) still marks transaction for rollback (exception thrown when exiting from method1).

3. Annotating both method1 and method2 as @Transactional(readOnly = true) still marks transaction for rollback (exception thrown when exiting from method1).

4. Annotating method2 with @Transactional(noRollbackFor = SomeException) prevents marking transaction for rollback (no exception thrown when exiting from method1).

5. Suppose method2 belongs to Service1. Invoking it from method1 does not go through Spring's proxy, i.e. Spring is unaware of SomeException thrown out of method2. Transaction is not marked for rollback in this case.

6. Suppose method2 is not annotated with @Transactional. Invoking it from method1 does go through Spring's proxy, but Spring pays no attention to exceptions thrown. Transaction is not marked for rollback in this case.

7. Annotating method2 with @Transactional(propagation = Propagation.REQUIRES_NEW) makes method2 start new transaction. That second transaction is marked for rollback upon exit from method2 but original transaction is unaffected in this case (no exception thrown when exiting from method1).

8. In case SomeException is checked (does not extend RuntimeException), Spring by default does not mark transaction for rollback when intercepting checked exceptions (no exception thrown when exiting from method1).

See all scenarios tested in this gist.

I try to avoid floating elements unless the design really needs it. Because you have floated the <li> they are out of normal flow.

If you add .navigation { text-align:center; } and change .navigation li { float: left; } to .navigation li { display: inline-block; } then entire navigation will be centred.

One caveat to this approach is that display: inline-block; is not supported in IE6 and needs a workaround to make it work in IE7.

System is a class of java.lang package, out is an object of PrintStream class and also static data member of System class, print() and println() is an instance method of PrintStream class. it is provide soft output on console.

On windows (cygwin + g++), I've found it necessary to add the flag -D_XOPEN_SOURCE=500 for the preprocessor to process the definition of M_PI in math.h.

In my case this solution is useful:

Solution: Disable the "Just My Code" option in the Debugging/General settings.

You can use the CSS property pointer-events to disable the click event on any element:

https://developer.mozilla.org/en-US/docs/Web/CSS/pointer-events

// To disable:    
document.getElementById('id').style.pointerEvents = 'none';
// To re-enable:
document.getElementById('id').style.pointerEvents = 'auto'; 
// Use '' if you want to allow CSS rules to set the value

I know it's a several years old post and you may solve your problem with above solution. However, i just want to suggest using InverseProperty for someone who still need. At least you don't need to change anything in OnModelCreating.

The below code is un-tested.

public class Team
{
    [Key]
    public int TeamId { get; set;} 
    public string Name { get; set; }

    [InverseProperty("HomeTeam")]
    public virtual ICollection<Match> HomeMatches { get; set; }

    [InverseProperty("GuestTeam")]
    public virtual ICollection<Match> GuestMatches { get; set; }
}


public class Match
{
    [Key]
    public int MatchId { get; set; }

    public float HomePoints { get; set; }
    public float GuestPoints { get; set; }
    public DateTime Date { get; set; }

    public virtual Team HomeTeam { get; set; }
    public virtual Team GuestTeam { get; set; }
}

I had the same problem of "gpg: keyserver timed out" with a couple of different servers. Finally, it turned out that I didn't need to do that manually at all. On a Debian system, the simple solution which fixed it was just (as root or precede with sudo):

aptitude install debian-archive-keyring

In case it is some other keyring you need, check out

apt-cache search keyring | grep debian

My squeeze system shows all these:

debian-archive-keyring       - GnuPG archive keys of the Debian archive
debian-edu-archive-keyring   - GnuPG archive keys of the Debian Edu archive
debian-keyring               - GnuPG keys of Debian Developers
debian-ports-archive-keyring - GnuPG archive keys of the debian-ports archive
emdebian-archive-keyring     - GnuPG archive keys for the emdebian repository

As Matt said, the curly braces are for concatenation. The extra curly braces around 16{a[15]} are the replication operator. They are described in the IEEE Standard for Verilog document (Std 1364-2005), section "5.1.14 Concatenations".

{16{a[15]}}

is the same as

{ 
   a[15], a[15], a[15], a[15], a[15], a[15], a[15], a[15],
   a[15], a[15], a[15], a[15], a[15], a[15], a[15], a[15]
}

In bit-blasted form,

assign result = {{16{a[15]}}, {a[15:0]}};

is the same as:

assign result[ 0] = a[ 0];
assign result[ 1] = a[ 1];
assign result[ 2] = a[ 2];
assign result[ 3] = a[ 3];
assign result[ 4] = a[ 4];
assign result[ 5] = a[ 5];
assign result[ 6] = a[ 6];
assign result[ 7] = a[ 7];
assign result[ 8] = a[ 8];
assign result[ 9] = a[ 9];
assign result[10] = a[10];
assign result[11] = a[11];
assign result[12] = a[12];
assign result[13] = a[13];
assign result[14] = a[14];
assign result[15] = a[15];
assign result[16] = a[15];
assign result[17] = a[15];
assign result[18] = a[15];
assign result[19] = a[15];
assign result[20] = a[15];
assign result[21] = a[15];
assign result[22] = a[15];
assign result[23] = a[15];
assign result[24] = a[15];
assign result[25] = a[15];
assign result[26] = a[15];
assign result[27] = a[15];
assign result[28] = a[15];
assign result[29] = a[15];
assign result[30] = a[15];
assign result[31] = a[15];

In case that you want combine a List of CompletableFutures, you can do this :

List<CompletableFuture<Void>> futures = new ArrayList<>();
// ... Add futures to this ArrayList of CompletableFutures

// CompletableFuture.allOf() method demand a variadic arguments
// You can use this syntax to pass a List instead
CompletableFuture<Void> allFutures = CompletableFuture.allOf(
            futures.toArray(new CompletableFuture[futures.size()]));

// Wait for all individual CompletableFuture to complete
// All individual CompletableFutures are executed in parallel
allFutures.get();

For more details on Future & CompletableFuture, useful links:
1. Future: https://www.baeldung.com/java-future
2. CompletableFuture: https://www.baeldung.com/java-completablefuture
3. CompletableFuture: https://www.callicoder.com/java-8-completablefuture-tutorial/

Its very simple:

For ObjC:

     NSString *string1 = @"This is";
     NSString *string2 = @"Swift Language";

ForSwift:

    let string1 = "This is"
    let string2 = "Swift Language"

For ObjC AppendString:

     NSString *appendString=[NSString stringWithFormat:@"%@ %@",string1,string2];

For Swift AppendString:

    var appendString1 = "\(string1) \(string2)"
    var appendString2 = string1+string2

Result:

    print("APPEND STRING 1:\(appendString1)")
    print("APPEND STRING 2:\(appendString2)")

Complete Code In Swift:

    let string1 = "This is"
    let string2 = "Swift Language"
    var appendString = "\(string1) \(string2)"
    var appendString1 = string1+string2
    print("APPEND STRING1:\(appendString1)")
    print("APPEND STRING2:\(appendString2)")

Someone with a requirement where they have to read from bits, lets say you have to read from only 3 bits but you need signed integer then use following:

data is of type: java.util.BitSet

new BigInteger(data.toByteArray).intValue() << 32 - 3 >> 32 - 3

The magic number 3 can be replaced with the number of bits (not bytes) you are using.

You can try this way also,

Html:

<form action="javascript:next()" method="post">
<input type="submit" value=Submit /></form>

Javascript:

      function next(){
        //Location where you want to forward your values
        window.location.href = "http://localhost:8563/And/try1.jsp?dymanicValue=" + values; 
        }

This is not actually a development issue. It happens due to expiration of the Apple Worldwide Developer Relations Intermediate Certificate issued by Apple Worldwide Developer Relations Certificate Authority. WWDRCA issues the certificate to sign your software for Apple devices, allowing our systems to confirm that your software is delivered to users as intended and has not been modified.

To resolve this issue, you have to follow the below steps:

1. Open Keychain Access
2. Go to View -> Show Expired Certificates

3. Go to System in Keychain

4. Here you find that "Apple Worldwide Developer Relations Certificate Authority" is marked as expired. So delete it. Also check under Login Tab and delete expired WWDRCA.

5. Download new WWDR Intermediate Certificate from here(The renewed Apple Worldwide Developer Relations Certification Intermediate Certificate will expire on February 7, 2023).

6. Install it by double clicking on it.

If you still face any issue with your iOS apps, Mac apps, Safari extensions, Apple Wallet and Safari push notifications, then please follow this link of expiration.

The Apple Worldwide Developer Relations Certification Intermediate Certificate expires soon and we've issued a renewed certificate that must be included when signing all new Apple Wallet Passes, push packages for Safari Push Notifications, and Safari Extensions starting February 14, 2016.

While most developers and users will not be affected by the certificate change, we recommend that all developers download and install the renewed certificate on their development systems and servers as a best practice. All apps will remain available on the App Store for iOS, Mac, and Apple TV.

If you want to add the current date into the database, I would avoid calculating the date in Java to begin with. Determining "now" on the Java (client) side leads to possible inconsistencies in the database if the client side is mis-configured, has the wrong time, wrong timezone, etc. Instead, the date can be set on the server side in a manner such as the following:

requestSQL = "INSERT INTO CREDIT_REQ_TITLE_ORDER ("   +
                "REQUEST_ID, ORDER_DT, FOLLOWUP_DT) " +
                "VALUES(?, SYSDATE, SYSDATE + 30)";

...

prs.setInt(1, new Integer(requestID));

This way, only one bind parameter is required and the dates are calculated on the server side will be consistent. Even better would be to add an insert trigger to CREDIT_REQ_TITLE_ORDER and have the trigger insert the dates. That can help enforce consistency between different client apps (for example, someone trying to do a fix via sqlplus.

    <div class="col-md-12">
      <p style="color: #28a745; font-weight: bold; font-size:25px; text-align: right " >Total Productos a pagar= {{ getTotal() }} {{ getResult() | currency }}
      <button class="btn btn-success" type="submit" [disabled]="!getResult()" (click)="onSubmit()">
        Ver Pedido
      </button>
     </p>
    </div>

It wouldn't be wrong to mention that Pexpect does throw a similar error

#python -c "import pexpect; p=pexpect.spawn('/usr/local/ssl/bin/openssl_1.1.0f  version'); p.interact()"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/site-packages/pexpect.py", line 430, in __init__
    self._spawn (command, args)
  File "/usr/lib/python2.7/site-packages/pexpect.py", line 560, in _spawn
    os.execv(self.command, self.args)
OSError: [Errno 8] Exec format error

Over here, the openssl_1.1.0f file at the specified path has exec command specified in it and is running the actual openssl binary when called.

Usually, I wouldn't mention this unless I have the root cause, but this problem was not there earlier. Unable to find the similar problem, the closest explanation to make it work is the same as the one provided by @jfs above.

what worked for me is both

• adding /bin/bash at the beginning of the command or file you are
  facing the problem with, or
• adding shebang #!/bin/sh as the first line.

for ex.

#python -c "import pexpect; p=pexpect.spawn('/bin/bash /usr/local/ssl/bin/openssl_1.1.0f  version'); p.interact()"
OpenSSL 1.1.0f  25 May 2017

I want to do this programmatically in unit tests, I do have the luxury of typing it out.

My solution is:

var dict = JsonConvert.DeserializeObject<ExpandoObject>(json) as IDictionary<string, object>;

Now I can assert that

dict.ContainsKey("ExpectedProperty");

SELECT  dateadd(dd,DAYS,'2013-09-07 00:00:00') DATES
INTO        #TEMP1
FROM
(SELECT TOP 365 colorder - 1 AS DAYS from master..syscolumns 
    WHERE id = -519536829 order by colorder) a

WHERE datediff(dd,dateadd(dd,DAYS,'2013-09-07 00:00:00'),'2013-09-13 00:00:00' ) >= 0 
    AND  dateadd(dd,DAYS,'2013-09-07 00:00:00') <=  '2013-09-13 00:00:00'  
    SELECT * FROM #TEMP1

++ This worked for me. It's vanilla javascirpt and good for use cases such as de-cluttering when testing with ngMocks library:

<!-- specRunner.html - keep this at the top of your <script> asset loading so that it is available readily -->
<!--  Frienly tip - have all JSON files in a json-data folder for keeping things organized-->
<script src="json-data/findByIdResults.js" charset="utf-8"></script>
<script src="json-data/movieResults.js" charset="utf-8"></script>

This is your javascript file that contains the JSON data

// json-data/JSONFindByIdResults.js
var JSONFindByIdResults = {
     "Title": "Star Wars",
     "Year": "1983",
     "Rated": "N/A",
     "Released": "01 May 1983",
     "Runtime": "N/A",
     "Genre": "Action, Adventure, Sci-Fi",
     "Director": "N/A",
     "Writer": "N/A",
     "Actors": "Harrison Ford, Alec Guinness, Mark Hamill, James Earl Jones",
     "Plot": "N/A",
     "Language": "English",
     "Country": "USA",
     "Awards": "N/A",
     "Poster": "N/A",

     "imdbVotes": "342",
     "imdbID": "tt0251413",
     "Type": "game",
     "Response": "True"
};

Finally, work with the JSON data anywhere in your code

// working with JSON data in code
var findByIdResults = window.JSONFindByIdResults;

Note:- This is great for testing and even karma.conf.js accepts these files for running tests as seen below. Also, I recommend this only for de-cluttering data and testing/development environment.

// extract from karma.conf.js
files: [
     'json-data/JSONSearchResultHardcodedData.js',
     'json-data/JSONFindByIdResults.js'
     ...
]

Hope this helps.

UPDATE

An easier way that worked for me is just include a function at the bottom of the code returning whatever JSON.

// within test code
let movies = getMovieSearchJSON();
.....
...
...
....
// way down below in the code
function getMovieSearchJSON() {
      return {
         "Title": "Bri Squared",
         "Year": "2011",
         "Rated": "N/A",
         "Released": "N/A",
         "Runtime": "N/A",
         "Genre": "Comedy",
         "Director": "Joy Gohring",
         "Writer": "Briana Lane",
         "Actors": "Brianne Davis, Briana Lane, Jorge Garcia, Gabriel Tigerman",
         "Plot": "N/A",
         "Language": "English",

Here is a cleaner way to do it if you are using Bootstrap 3.2.0.

Link HTML

<a href="#my_modal" data-toggle="modal" data-book-id="my_id_value">Open Modal</a>

Modal JavaScript

//triggered when modal is about to be shown
$('#my_modal').on('show.bs.modal', function(e) {

    //get data-id attribute of the clicked element
    var bookId = $(e.relatedTarget).data('book-id');

    //populate the textbox
    $(e.currentTarget).find('input[name="bookId"]').val(bookId);
});

http://jsfiddle.net/k7FC2/

I have solved similar problems by writing a Generic Extension Property Attribute Helper:

using System;
using System.Linq;
using System.Linq.Expressions;
using System.Reflection;

public static class AttributeHelper
{
    public static TValue GetPropertyAttributeValue<T, TOut, TAttribute, TValue>(
        Expression<Func<T, TOut>> propertyExpression, 
        Func<TAttribute, TValue> valueSelector) 
        where TAttribute : Attribute
    {
        var expression = (MemberExpression) propertyExpression.Body;
        var propertyInfo = (PropertyInfo) expression.Member;
        var attr = propertyInfo.GetCustomAttributes(typeof(TAttribute), true).FirstOrDefault() as TAttribute;
        return attr != null ? valueSelector(attr) : default(TValue);
    }
}

Usage:

var author = AttributeHelper.GetPropertyAttributeValue<Book, string, AuthorAttribute, string>(prop => prop.Name, attr => attr.Author);
// author = "AuthorName"

On MVC 5 is quite similar

@Html.ActionLink("LinkText", "ActionName", new { id = "id" })

Some CSS :

table td, table td * {
    vertical-align: top;
}

The full command would be something like below, notice the quotes

icacls "c:\inetpub\wwwroot\tmp" /grant "IIS AppPool\DefaultAppPool:F"

FYI: The 3.0 Google Analytics API will automatically refresh the access token if you have a refresh token when it expires so your script never needs refreshToken.

(See the Sign function in auth/apiOAuth2.php)

You cannot update it. You'll have to save the document using a new _id, and then remove the old document.

// store the document in a variable
doc = db.clients.findOne({_id: ObjectId("4cc45467c55f4d2d2a000002")})

// set a new _id on the document
doc._id = ObjectId("4c8a331bda76c559ef000004")

// insert the document, using the new _id
db.clients.insert(doc)

// remove the document with the old _id
db.clients.remove({_id: ObjectId("4cc45467c55f4d2d2a000002")})

Like a lot of functions, this one can be used in many different ways to solve many different problems, I think of it as yet another tool in our toolbelts.

So far, the discussion has focused heavily on simply hiding an ID, but that is only one value, why not use it for lots of values! That is what I am doing, I use it to load up the values in a class only one view at a time, because html.beginform creates a new object and if your model object for that view already had some values passed to it, those values will be lost unless you provide a reference to those values in the beginform.

To see a great motivation for the html.hiddenfor, I recommend you see Passing data from a View to a Controller in .NET MVC - "@model" not highlighting

As stated by the earlier answer you can get both mysql server and client libs by running

brew install mysql.

There is also client only installation. To install only client libraries run

brew install mysql-connector-c

In order to run these commands, you need homebrew package manager in your mac. You can install it by running

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

So in Short,

vi ~/.proxy_info

export http_proxy=<username>:<password>@<proxy>:8080
export https_proxy=<username>:<password>@<proxy>:8080

source ~/.proxy_info

Hope this helps someone in hurry :)

Check C:\Users\User path. Change User directory name (may be something different name) from your alphabet to English alphabet. Warning: it is dangerous operation, learn it before changing. Android Studio can not access to AVD throw users\Your alphabet name\.android.

Assuming your controller's action method is something like this:

public ActionResult AllCategories(int id = 0)
{
    return View(db.Categories.Include(p => p.Products).ToList());
}

Modify your models to be something like this:

public class Product
{
    [Key]
    public int ID { get; set; }
    public int CategoryID { get; set; }
    //new code
    public virtual Category Category { get; set; }
    public string Title { get; set; }
    public string Description { get; set; }
    public string Path { get; set; }

    //remove code below
    //public virtual ICollection<Category> Categories { get; set; }
}

public class Category
{
    [Key]
    public int CategoryID { get; set; }
    public string Name { get; set; }
    //new code
    public virtual ICollection<Product> Products{ get; set; }
}

Then your since now the controller takes in a Category as Model (instead of a Product):

foreach (var category in Model)
{
    <h3><u>@category.Name</u></h3>
    <div>
        <ul>    
            @foreach (var product in Model.Products)
            {
                // cut for brevity, need to add back more code from original
                <li>@product.Title</li>
            }
        </ul>
    </div>
}

UPDATED: Add ToList() to the controller return statement.

Try ClassGraph. (Disclaimer, I am the author). ClassGraph supports scanning for subclasses of a given class, either at runtime or at build time, but also much more. ClassGraph can build an abstract representation of the entire class graph (all classes, annotations, methods, method parameters, and fields) in memory, for all classes on the classpath, or for classes in selected packages, and you can query this class graph however you want. ClassGraph supports more classpath specification mechanisms and classloaders than any other scanner, and also works seamlessly with the new JPMS module system, so if you base your code on ClassGraph, your code will be maximally portable. See the API here.

I had this same problem with this part of my code:

const newComment = {
    dishId: dishId,
    rating: rating,
    author: author,
    comment: comment
};
newComment.date = new Date().toISOString();

Same error, const is a reserved word.

The thing is, I made the .eslintrc.js from the link you gave in the update and still got the same error. Also, I get an parsing error in the .eslintrc.js: Unexpected token ':'.

Right in this part:

"env": {
"browser": true,
"node": true,
"es6": true
},

Both are DBMS's Product Sql server is an commercial application while MySql is an opensouces application.Both the product include similar feature,however sql server should be used for an enterprise solution ,while mysql might suit a smaller implementation.if you need feature like recovery,replication,granalar security and significant,you need sql server

MySql takes up less spaces on disk, and uses less memory and cpu than does sql server

You can try changing it to this:

If myTableData.Rows.Count > 0 Then
  For i As Integer = 0 To myTableData.Rows.Count - 1
    ''Dim DataType() As String = myTableData.Rows(i).Item(1)
    ListBox2.Items.Add(myTableData.Rows(i)(1))
  Next
End If

Note: Your loop needs to be one less than the row count since it's a zero-based index.

myList[1] is an element of myList and it's type is string.

myList[1] is str, you can not append to it. myList is a list, you should have been appending to it.

>>> myList = [1, 'from form', [1,2]]
>>> myList[1]
'from form'
>>> myList[2]
[1, 2]
>>> myList[2].append('t')
>>> myList
[1, 'from form', [1, 2, 't']]
>>> myList[1].append('t')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'str' object has no attribute 'append'
>>> 

Also I think if_exists was used like:

Hi ${userName?if_exists}, How are you?

which will not break if userName is null, the result if null would be:

Hi , How are you?

if_exists is now deprecated and has been replaced with the default operator ! as in

Hi ${userName!}, How are you?

the default operator also supports a default value, such as:

Hi ${userName!"John Doe"}, How are you?

<a href="..">no JS needed</a>

.. means parent directory.

you could submit all parameters with such naming:

params[0][topdiameter]
params[0][bottomdiameter]
params[1][topdiameter]
params[1][bottomdiameter]

then later you do something like this:

foreach ($_REQUEST['params'] as $item) {
    echo $item['topdiameter'];
    echo $item['bottomdiameter'];
}

You just need one line:

from django.contrib.auth.decorators import user_passes_test  

@user_passes_test(lambda u: u.groups.filter(name='companyGroup').exists())
def you_view():
    return HttpResponse("Since you're logged in, you can see this text!")

User interactive approach:

git clean -i -fd

Remove .classpath [y/N]? N
Remove .gitignore [y/N]? N
Remove .project [y/N]? N
Remove .settings/ [y/N]? N
Remove src/com/amazon/arsdumpgenerator/inspector/ [y/N]? y
Remove src/com/amazon/arsdumpgenerator/manifest/ [y/N]? y
Remove src/com/amazon/arsdumpgenerator/s3/ [y/N]? y
Remove tst/com/amazon/arsdumpgenerator/manifest/ [y/N]? y
Remove tst/com/amazon/arsdumpgenerator/s3/ [y/N]? y

-i for interactive
-f for force
-d for directory
-x for ignored files(add if required)

Note: Add -n or --dry-run to just check what it will do.

You could use the timeout setting in the ajax options like this:

$.ajax({
    url: "test.html",
    timeout: 3000,
    error: function(){
        //do something
    },
    success: function(){
        //do something
    }
});

Read all about the ajax options here: http://api.jquery.com/jQuery.ajax/

Remember that when a timeout occurs, the error handler is triggered and not the success handler :)

If you need specific columns printed with arbitrary delimeter:

awk '{print $3 "  " $4}'

col#3 col#4

awk '{print $3 "anything" $4}'

col#3anythingcol#4

So if you have whitespace in a column it will be two columns, but you can connect it with any delimiter or without it.

It's possible that you still need to add the JDK into Eclipse (STS). Just because the JDK is on the system doesn't mean Eclipse knows where to find it.

Go to Preferences > Java > Installed JREs

If there is not an entry for the 1.7 JDK, add it. You'll have to point Eclipse to where you installed your 1.7 JDK.

If Eclipse can't find a JRE that is 1.7 compatible, I'm guessing that it just uses your default JRE, and that's probably still pointing at Java 1.6, which would be causing your red squiggly lines.

I know you said "ignore what the macro does", but people will find this question by searching based on the title, so I think discussion of further techniques to emulate functions with macros are warranted.

Closest I know of is:

#define MACRO(X,Y) \
do { \
    auto MACRO_tmp_1 = (X); \
    auto MACRO_tmp_2 = (Y); \
    using std::cout; \
    using std::endl; \
    cout << "1st arg is:" << (MACRO_tmp_1) << endl;    \
    cout << "2nd arg is:" << (MACRO_tmp_2) << endl;    \
    cout << "Sum is:" << (MACRO_tmp_1 + MACRO_tmp_2) << endl; \
} while(0)

This does the following:

• Works correctly in each of the stated contexts.
• Evaluates each of its arguments exactly once, which is a guaranteed feature of a function call (assuming in both cases no exceptions in any of those expressions).
• Acts on any types, by use of "auto" from C++0x. This is not yet standard C++, but there's no other way to get the tmp variables necessitated by the single-evaluation rule.
• Doesn't require the caller to have imported names from namespace std, which the original macro does, but a function would not.

However, it still differs from a function in that:

• In some invalid uses it may give different compiler errors or warnings.
• It goes wrong if X or Y contain uses of 'MACRO_tmp_1' or 'MACRO_tmp_2' from the surrounding scope.
• Related to the namespace std thing: a function uses its own lexical context to look up names, whereas a macro uses the context of its call site. There's no way to write a macro that behaves like a function in this respect.
• It can't be used as the return expression of a void function, which a void expression (such as the comma solution) can. This is even more of an issue when the desired return type is not void, especially when used as an lvalue. But the comma solution can't include using declarations, because they're statements, so pick one or use the ({ ... }) GNU extension.

In your specific case, you can do it just with a boring old counter:

var index, value, result;
for (index = 0; index < windowArray.length; ++index) {
    value = windowArray[index];
    if (value.substring(0, 3) === "id-") {
        // You've found it, the full text is in `value`.
        // So you might grab it and break the loop, although
        // really what you do having found it depends on
        // what you need.
        result = value;
        break;
    }
}

// Use `result` here, it will be `undefined` if not found

But if your array is sparse, you can do it more efficiently with a properly-designed for..in loop:

var key, value, result;
for (key in windowArray) {
    if (windowArray.hasOwnProperty(key) && !isNaN(parseInt(key, 10))) {
        value = windowArray[key];
        if (value.substring(0, 3) === "id-") {
            // You've found it, the full text is in `value`.
            // So you might grab it and break the loop, although
            // really what you do having found it depends on
            // what you need.
            result = value;
            break;
        }
    }
}

// Use `result` here, it will be `undefined` if not found

Beware naive for..in loops that don't have the hasOwnProperty and !isNaN(parseInt(key, 10)) checks; here's why.

Off-topic:

Another way to write

var windowArray = new Array ("item","thing","id-3-text","class");

is

var windowArray = ["item","thing","id-3-text","class"];

...which is less typing for you, and perhaps (this bit is subjective) a bit more easily read. The two statements have exactly the same result: A new array with those contents.

A much faster alternative I usually use is as follows, as I can "or" an arbitrary number of conditions that can fit in variable space

@(
  Echo off
  Set "_Match= 1 2 3 "
)

Set /a "var=3"

Echo:%_Match%|Find " %var% ">nul || (
  REM Code for a false condition goes here
) && (
  REM code for a true condition goes here.
)

As of version 3.0.0, you can get the current route by calling:

this.context.router.location.pathname

Sample code is below:

var NavLink = React.createClass({
    contextTypes: {
        router: React.PropTypes.object
    },

    render() {   
        return (
            <Link {...this.props}></Link>
        );
    }
});

These two procedures let me reset the sequence and reset the sequence based on data in a table (apologies for the coding conventions used by this client):

CREATE OR REPLACE PROCEDURE SET_SEQ_TO(p_name IN VARCHAR2, p_val IN NUMBER)
AS
   l_num   NUMBER;
BEGIN
   EXECUTE IMMEDIATE 'select ' || p_name || '.nextval from dual' INTO l_num;

   -- Added check for 0 to avoid "ORA-04002: INCREMENT must be a non-zero integer"
   IF (p_val - l_num - 1) != 0
   THEN
      EXECUTE IMMEDIATE 'alter sequence ' || p_name || ' increment by ' || (p_val - l_num - 1) || ' minvalue 0';
   END IF;

   EXECUTE IMMEDIATE 'select ' || p_name || '.nextval from dual' INTO l_num;

   EXECUTE IMMEDIATE 'alter sequence ' || p_name || ' increment by 1 ';

   DBMS_OUTPUT.put_line('Sequence ' || p_name || ' is now at ' || p_val);
END;

CREATE OR REPLACE PROCEDURE SET_SEQ_TO_DATA(seq_name IN VARCHAR2, table_name IN VARCHAR2, col_name IN VARCHAR2)
AS
   nextnum   NUMBER;
BEGIN
   EXECUTE IMMEDIATE 'SELECT MAX(' || col_name || ') + 1 AS n FROM ' || table_name INTO nextnum;

   SET_SEQ_TO(seq_name, nextnum);
END;

You can use zip with * to get transpose of a matrix:

>>> A = [[ 1, 2, 3],[ 4, 5, 6]]
>>> zip(*A)
[(1, 4), (2, 5), (3, 6)]
>>> lis  = [[1,2,3], 
... [4,5,6],
... [7,8,9]]
>>> zip(*lis)
[(1, 4, 7), (2, 5, 8), (3, 6, 9)]

If you want the returned list to be a list of lists:

>>> [list(x) for x in zip(*lis)]
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]
#or
>>> map(list, zip(*lis))
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]

JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.

var textBox = document.getElementById("myTextBox");
var textLength = textBox.value.length;
if(textLength > 5)
{
    //red
    textBox.style.backgroundColor = "#FF0000";
}
else
{
    //green
    textBox.style.backgroundColor = "#00FF00";
}

Also, check for the possibility of a tiny typo:

It's rest_framework with an underscore (_) in between!

Took me a while to figure out that I was using a dash instead...

For me, restarting Docker Desktop did not help. Shutting down Win10 and start it again, it did help.

I searched for a simple solution and this works well for me:

//input data
view = new Uint8Array(data);

//output string
serialString = ua2text(view);

//convert UTF8 to string
function ua2text(ua) {
    s = "";
    for (var i = 0; i < ua.length; i++) {
        s += String.fromCharCode(ua[i]);
    }
    return s;               
}

Only issue I have is sometimes I get one character at a time. This might be by design with my source of the arraybuffer. I'm using https://github.com/xseignard/cordovarduino to read serial data on an android device.

Definitely, we cannot override static methods in Java. Because JVM resolves correct overridden method based upon the object at run-time by using dynamic binding in Java.

However, the static method in Java is associated with Class rather than the object and resolved and bonded during compile time.

Try This

SELECT f.*
FROM first_table f LEFT JOIN second_table s ON f.key=s.key
WHERE s.key is NULL

Use kebab-case for all package, folder and file names.

Why?

You should imagine that any folder or file might be extracted to its own package some day. Packages cannot contain uppercase letters.

New packages must not have uppercase letters in the name. https://docs.npmjs.com/files/package.json#name

Therefore, camelCase should never be used. This leaves snake_case and kebab-case.

kebab-case is by far the most common convention today. The only use of underscores is for internal node packages, and this is simply a convention from the early days.

if you can dodge the single quotes:

__='
blah blah comment.

Suprised no-one has yet mentioned the recommended solution in the Python 3 docs:

See also:

• The linspace recipe shows how to implement a lazy version of range that suitable for floating point applications.

Once defined, the recipe is easy to use and does not require numpy or any other external libraries, but functions like numpy.linspace(). Note that rather than a step argument, the third num argument specifies the number of desired values, for example:

print(linspace(0, 10, 5))
# linspace(0, 10, 5)
print(list(linspace(0, 10, 5)))
# [0.0, 2.5, 5.0, 7.5, 10]

I quote a modified version of the full Python 3 recipe from Andrew Barnert below:

import collections.abc
import numbers

class linspace(collections.abc.Sequence):
    """linspace(start, stop, num) -> linspace object

    Return a virtual sequence of num numbers from start to stop (inclusive).

    If you need a half-open range, use linspace(start, stop, num+1)[:-1].
    """
    def __init__(self, start, stop, num):
        if not isinstance(num, numbers.Integral) or num <= 1:
            raise ValueError('num must be an integer > 1')
        self.start, self.stop, self.num = start, stop, num
        self.step = (stop-start)/(num-1)
    def __len__(self):
        return self.num
    def __getitem__(self, i):
        if isinstance(i, slice):
            return [self[x] for x in range(*i.indices(len(self)))]
        if i < 0:
            i = self.num + i
        if i >= self.num:
            raise IndexError('linspace object index out of range')
        if i == self.num-1:
            return self.stop
        return self.start + i*self.step
    def __repr__(self):
        return '{}({}, {}, {})'.format(type(self).__name__,
                                       self.start, self.stop, self.num)
    def __eq__(self, other):
        if not isinstance(other, linspace):
            return False
        return ((self.start, self.stop, self.num) ==
                (other.start, other.stop, other.num))
    def __ne__(self, other):
        return not self==other
    def __hash__(self):

This error apears when you have some form controls (like Inputs, Selects, etc) in your form group tags with no formControlName property.

Those examples throws the error:

<form [formGroup]="myform">
    <input type="text">
    <input type="text" [ngmodel]="nameProperty">
    <input type="text" [formGroup]="myform" [name]="name">
</fom>

There are two ways, the stand alone:

<form [formGroup]="myform">
    <input type="text" [ngModelOptions]="{standalone: true}">
    <input type="text" [ngmodel]="nameProperty" [ngModelOptions]="{standalone: true}">
    <!-- input type="text" [formGroup]="myform" [name]="name" --> <!-- no works with standalone --
</form>

Or including it into the formgroup

<form [formGroup]="myform">
    <input type="text" formControlName="field1">
    <input type="text" formControlName="nameProperty">
    <input type="text" formControlName="name">
</fom>

The last one implies to define them in the initialization formGroup

this.myForm =  new FormGroup({
    field1: new FormControl(''),
    nameProperty: new FormControl(''),
    name: new FormControl('')
});

You have an array that is the "hash table".

In Open Hashing each cell in the array points to a list containg the collisions. The hashing has produced the same index for all items in the linked list.

In Closed Hashing you use only one array for everything. You store the collisions in the same array. The trick is to use some smart way to jump from collision to collision unitl you find what you want. And do this in a reproducible / deterministic way.

stringWithFileSystemRepresentation doesn't appear to be available in iOS.

Maybe I read the problem wrong, but I believe you already have inserted the course 11 records and simply need to update those that meet the criteria you listed with course 6's data.

If this is the case, you'll want to use an UPDATE...FROM statement:

UPDATE MyTable
SET
    complete = 1,
    complete_date = newdata.complete_date,
    post_score = newdata.post_score
FROM
    (
    SELECT
        userID,
        complete_date,
        post_score
    FROM MyTable
    WHERE
        courseID = 6
        AND complete = 1
        AND complete_date > '8/1/2008'
    ) newdata
WHERE
    CourseID = 11
    AND userID = newdata.userID

I had the same problem but now I got it: Check which API you are selecting and for that API version is CPU/ABI available or not. If it's available then your work is done. Select the device according to the windows supporting it.

  int month = Convert.ToInt32(ddlMonth.SelectedValue);/*Store month Value From page*/
  int year = Convert.ToInt32(txtYear.Value);/*Store Year Value From page*/
  int days = System.DateTime.DaysInMonth(year, month); /*this will store no. of days for month, year that we store*/

The download attribute is not supported in IE (see http://caniuse.com/#search=download%20attribute).

That suggests the download attribute is only supported by firefox, chrome, opera and the latest version of blackberry's browser.

For other browsers you'll need to use more traditional methods to force download. That is server side code is necessary to set an appropriate Content-Type and Content-Disposition header to tell (or trick depending on your point of view) the browser to download the item. Headers should look like this:

Content-Type: application/octet-stream
Content-Disposition: attachment;filename=\"filename.xxx\"

(thanks to antyrat for the copy and paste of the headers)

Just to suggest another way without using if statements, you can use the get() method for DataFrames. For performing the sum based on the question:

df['sum'] = df.get('A', df['B']) + df['C']

The DataFrame get method has similar behavior as python dictionaries.

Installing Drivers for Arduino in Windows 8 / 7.

( I tried it for Uno r3, but i believe it will work for all Arduino Boards )

Plugin your Arduino Board

Go to Control Panel ---> System and Security ---> System ---> On the left pane Device Manger

Expand Other Devices.

Under Other Devices you will notice a icon with a small yellow error graphic. (Unplug all your other devices attached to any Serial Port)

Right Click on that device ---> Update Driver Software

Select Browse my computer for Driver Software

Click on Browse ---> Browse for the folder of Arduino Environment which you have downloaded from Arduino website. If not downloaded then http://arduino.cc/en/Main/Software

After Browsing mark include subfolder.

Click next ---> Your driver will be installed.

Collapse Other Devices ---> Expand Port ( its in device manager only under other devices )

You will see Arduino Written ---> Look for its COM PORT (close device manager)

Go to Arduino Environment ---> Tools ---> Serial Port ---> Select the COM PORT as mentioned in PORT in device manager. (If you are using any other Arduino Board instead of UNO then select the same in boards )

Upload your killer programmes and see them work . . .

I hope this helps. . .

Welcome

I still experienced the problem described above on an Asus T100 Windows 10 test device for both (up to date) Edge and Chrome browser.

Solution was in the date/time settings of the device; somehow the date was not set correctly (date in the past). Restoring this by setting the correct date (and restarting the browsers) solved the issue for me. I hope I save someone a headache debugging this problem.

In response to Thomas Browne's comment, because lnmx's answer only works for subtracting a date, here is a modification of his code that works for subtracting time from a time.Time type.

package main

import (
    "fmt"
    "time"
)

func main() {
    now := time.Now()

    fmt.Println("now:", now)

    count := 10
    then := now.Add(time.Duration(-count) * time.Minute)
    // if we had fix number of units to subtract, we can use following line instead fo above 2 lines. It does type convertion automatically.
    // then := now.Add(-10 * time.Minute)
    fmt.Println("10 minutes ago:", then)
}

Produces:

now: 2009-11-10 23:00:00 +0000 UTC
10 minutes ago: 2009-11-10 22:50:00 +0000 UTC

Not to mention, you can also use time.Hour or time.Second instead of time.Minute as per your needs.

Playground: https://play.golang.org/p/DzzH4SA3izp

Based on the same idea as Super Type Tokens, you could create a typed id to use instead of a string:

public abstract class TypedID<T extends Animal> {
  public final Type type;
  public final String id;

  protected TypedID(String id) {
    this.id = id;
    Type superclass = getClass().getGenericSuperclass();
    if (superclass instanceof Class) {
      throw new RuntimeException("Missing type parameter.");
    }
    this.type = ((ParameterizedType) superclass).getActualTypeArguments()[0];
  }
}

But I think this may defeat the purpose, since you now need to create new id objects for each string and hold on to them (or reconstruct them with the correct type information).

Mouse jerry = new Mouse();
TypedID<Dog> spike = new TypedID<Dog>("spike") {};
TypedID<Duck> quacker = new TypedID<Duck>("quacker") {};

jerry.addFriend(spike, new Dog());
jerry.addFriend(quacker, new Duck());

But you can now use the class in the way you originally wanted, without the casts.

jerry.callFriend(spike).bark();
jerry.callFriend(quacker).quack();

This is just hiding the type parameter inside the id, although it does mean you can retrieve the type from the identifier later if you wish.

You'd need to implement the comparison and hashing methods of TypedID too if you want to be able to compare two identical instances of an id.

Yes: you can sort using a custom comparison function:

std::sort(info.begin(), info.end(), my_custom_comparison);

my_custom_comparison needs to be a function or a class with an operator() overload (a functor) that takes two data objects and returns a bool indicating whether the first is ordered prior to the second (i.e., first < second). Alternatively, you can overload operator< for your class type data; operator< is the default ordering used by std::sort.

Either way, the comparison function must yield a strict weak ordering of the elements.

My requirements were a bit stricter:

• I had to retain case info (the strings are paths to files displayed to the user, but it's a windows app so internally all operations must be case insensitive)
• I needed keys to be as small as possible (it did make a difference in memory performance, chopped off 110 mb out of 370). This meant that caching lowercase version of keys is not an option.
• I needed creation of the data structures to be as fast as possible (again made a difference in performance, speed this time). I had to go with a builtin

My initial thought was to substitute our clunky Path class for a case insensitive unicode subclass - but:

• proved hard to get that right - see: A case insensitive string class in python
• turns out that explicit dict keys handling makes code verbose and messy - and error prone (structures are passed hither and thither, and it is not clear if they have CIStr instances as keys/elements, easy to forget plus some_dict[CIstr(path)] is ugly)

So I had finally to write down that case insensitive dict. Thanks to code by @AaronHall that was made 10 times easier.

Implicit vs explicit is still a problem, but once dust settles, renaming of attributes/variables to start with ci (and a big fat doc comment explaining that ci stands for case insensitive) I think is a perfect solution - as readers of the code must be fully aware that we are dealing with case insensitive underlying data structures. This will hopefully fix some hard to reproduce bugs, which I suspect boil down to case sensitivity.

Comments/corrections welcome :)

After lots of trial i found [a-zA-Z\\s]* for Alphanumeric with white space

Example:

New York

New Delhi

If you want to insert other string somewhere else in existing string, you may use selection method below.

Calling character on second position:

>>> s = "0123456789"
>>> s[2]
'2'

Calling range with start and end position:

>>> s[4:6]
'45'

Calling part of a string before that position:

>>> s[:6]
'012345'

Calling part of a string after that position:

>>> s[4:]
'456789'

Inserting your string in 5th position.

>>> s = s[:5] + "L" + s[5:]
>>> s
'01234L56789'

Also s is equivalent to s[:].

With your question you can use all your string, i.e.

>>> s = "L" + s + "LL"

or if "L" is a some other string (for example I call it as l), then you may use that code:

>>> s = l + s + (l * 2)

Select user id from list of user id:

SELECT * FROM my_table WHERE user_id IN (1,3,5,7,9,4);

Delete your source tree that was gunzipped or gzipped and extracted to folder and reextract again. Supply your options again

./configure --with-option=/path/etc ...

Then if all libs are present, your make should succeed.

a.index(max(a))

will tell you the index of the first instance of the largest valued element of list a.

The route engine uses the same sequence as you add rules into it. Once it gets the first matched rule, it will stop checking other rules and take this to search for controller and action.

So, you should:

1. Put your specific rules ahead of your general rules(like default), which means use RouteTable.Routes.MapHttpRoute to map "WithActionApi" first, then "DefaultApi".

2. Remove the defaults: new { id = System.Web.Http.RouteParameter.Optional } parameter of your "WithActionApi" rule because once id is optional, url like "/api/{part1}/{part2}" will never goes into "DefaultApi".

3. Add an named action to your "DefaultApi" to tell the route engine which action to enter. Otherwise once you have more than one actions in your controller, the engine won't know which one to use and throws "Multiple actions were found that match the request: ...". Then to make it matches your Get method, use an ActionNameAttribute.

So your route should like this:

// Map this rule first
RouteTable.Routes.MapRoute(
     "WithActionApi",
     "api/{controller}/{action}/{id}"
 );

RouteTable.Routes.MapRoute(
    "DefaultApi",
    "api/{controller}/{id}",
    new { action="DefaultAction", id = System.Web.Http.RouteParameter.Optional }
);

And your controller:

[ActionName("DefaultAction")] //Map Action and you can name your method with any text
public string Get(int id)
{
    return "object of id id";
}        

[HttpGet]
public IEnumerable<string> ByCategoryId(int id)
{
    return new string[] { "byCategory1", "byCategory2" };
}

Following query working for me

when i have set default value of column 'NULL' then

select * from table where column IS NOT NULL

and when i have set default value nothing then

select * from table where column <>''

You can eventually extend the EL language by using the EL Functor, which will allow you to call any Java beans methods, even with parameters...

Pycharm shortcut for running "Selection" in the console is ALT + SHIFT + e

For this to work properly, you'll have to run everything this way.

Node.js 8.0.0 includes a new util.promisify() API that allows standard Node.js callback style APIs to be wrapped in a function that returns a Promise. An example use of util.promisify() is shown below.

const fs = require('fs');
const util = require('util');

const readFile = util.promisify(fs.readFile);

readFile('/some/file')
  .then((data) => { /** ... **/ })
  .catch((err) => { /** ... **/ });

This is how I handle the public assets. Here I use Phalcon PHP's Bootstrap method.

Folder Structure

|-.htaccess*
|-application/
|-public/
  |-.htaccess**
  |-index.php***
  |-css/
  |-js/
  |-img/
  |-font/
  |-upload/
|-system

Files to edit

1. .htaccess*

   All requests to the project will be rewritten to the public/ directory making it the document root. This step ensures that the internal project folders remain hidden from public viewing and thus eliminates security threats of this kind. - Phalconphp Doc

   <IfModule mod_rewrite.c>
       RewriteEngine on
       RewriteRule  ^$ public/    [L]
       RewriteRule  (.*) public/$1 [L]
   </IfModule>
   

2. .htaccess**

   Rules will check if the requested file exists and, if it does, it doesn’t have to be rewritten by the web server module. - Phalconphp Doc

   <IfModule mod_rewrite.c>
       RewriteEngine On
       RewriteCond %{REQUEST_FILENAME} !-d
       RewriteCond %{REQUEST_FILENAME} !-f
       RewriteRule ^(.*)$ index.php/$1 [QSA,L]
   </IfModule>
   

3. index.php***

   Modify the application path and the system path as,

   $system_path = '../system';
   $application_folder = '../application';
   

Now you use the public folder as base_url()."public/[YOUR ASSET FOLDER]"

Hope this helps :)

The @ symbol denotes an annotation type definition.

That means it is not really an interface, but rather a new annotation type -- to be used as a function modifier, such as @override.

See this javadocs entry on the subject.

Try this:

Open PgAdmin -> Files -> Open pgpass.conf

You would get the path of pgpass.conf at the bottom of the window. Go to that location and open this file, you can find your password there.

Reference

If the above does not work, you may consider trying this:

 1. edit pg_hba.conf to allow trust authorization temporarily
 2. Reload the config file (pg_ctl reload)
 3. Connect and issue ALTER ROLE / PASSWORD to set the new password
 4. edit pg_hba.conf again and restore the previous settings
 5. Reload the config file again

If a control is disabled it cannot be edited and its content is excluded when the form is submitted.

If a control is readonly it cannot be edited, but its content (if any) is still included with the submission.

For my project, I am set up to use https. I just got a new computer and cloned the project in git. The protocol and port number for the project are not saved in the solution file, so you have to make sure to set it again.

I think OldCurmudgeon and StaxMan are both correct but here is one sentence answer with simple example for you.

@JsonProperty(name), tells Jackson ObjectMapper to map the JSON property name to the annotated Java field's name.

//example of json that is submitted 
"Car":{
  "Type":"Ferrari",
}

//where it gets mapped 
public static class Car {
  @JsonProperty("Type")
  public String type;
 }

If you are using the modules system on the server side, you do not need to use Babel at all. To use modules in Node.js ensure that:

1. Use a version of node that supports the --experimental-modules flag
2. Your *.js files must then be renamed to *.mjs

That's it.

However and this is a big however, while your shinny pure ES6 code will run in an environment like Node.js (e.g., 9.5.0) you will still have the craziness of transpilling just to test. Also bear in mind that Ecma has stated that release cycles for JavaScript are going to be faster, with newer features delivered on a more regular basis. Whilst this will be no problems for single environments like Node.js, it's a slightly different proposition for browser environments. What is clear is that testing frameworks have a lot to do in catching up. You will still need to probably transpile for testing frameworks. I'd suggest using Jest.

Also be aware of bundling frameworks. You will be running into problems there.

Step1:

Go to cordova\platforms\android ant create a fille called ant.properties file with the keystore file info (this keystore can be generated from your favorite Android SDK, studio...):

key.store=C:\\yourpath\\Yourkeystore.keystore
key.alias=youralias

Step2:

Go to cordova path and execute:

cordova build android --release

Note: You will be prompted asking your keystore and key password

An YourApp-release.apk will appear in \cordova\platforms\android\ant-build

I just had the same problem and ended up doing:

git rebase -i HEAD~N

(N is the number of commits git will show you)

That prompts your text editor and then you can remove the commit you want by deleting the line associated with it.

I got this error because in my code I misspelled a component definition with lowercase react.createClass instead of uppercase React.createClass.

Herman's solution worked for me, but the ... had me mixed up for a bit. I'm including the demo I worked up based on his answer. The additional features in my answer include foreign key support, auto incrementing keys, and use of the last_insert_rowid() function to get the last auto generated key in a transaction.

My need for this information came up when I hit a transaction that required three foreign keys but I could only get the last one with last_insert_rowid().

PRAGMA foreign_keys = ON;   -- sqlite foreign key support is off by default
PRAGMA temp_store = 2;      -- store temp table in memory, not on disk

CREATE TABLE Foo(
    Thing1 INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL
);

CREATE TABLE Bar(
    Thing2 INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,
    FOREIGN KEY(Thing2) REFERENCES Foo(Thing1)
);

BEGIN TRANSACTION;

CREATE TEMP TABLE _Variables(Key TEXT, Value INTEGER);

INSERT INTO Foo(Thing1)
VALUES(2);

INSERT INTO _Variables(Key, Value)
VALUES('FooThing', last_insert_rowid());

INSERT INTO Bar(Thing2)
VALUES((SELECT Value FROM _Variables WHERE Key = 'FooThing'));

DROP TABLE _Variables;

END TRANSACTION;

You need to set a constraint on the table to trigger a "conflict" which you then resolve by doing a replace:

CREATE TABLE data   (id INTEGER PRIMARY KEY, event_id INTEGER, track_id INTEGER, value REAL);
CREATE UNIQUE INDEX data_idx ON data(event_id, track_id);

Then you can issue:

INSERT OR REPLACE INTO data VALUES (NULL, 1, 2, 3);
INSERT OR REPLACE INTO data VALUES (NULL, 2, 2, 3);
INSERT OR REPLACE INTO data VALUES (NULL, 1, 2, 5);

The "SELECT * FROM data" will give you:

2|2|2|3.0
3|1|2|5.0

Note that the data.id is "3" and not "1" because REPLACE does a DELETE and INSERT, not an UPDATE. This also means that you must ensure that you define all necessary columns or you will get unexpected NULL values.

I solved just by: given correct host and port so:

1. Open oracle net manager
2. Local
3. Listener

in Listener on address 2 then copy host to Oracle Developer

finally connect to oracle

This question already has the answer for defining function pointers, however they can get very messy, especially if you are going to be passing them around your application. To avoid this unpleasantness I would recommend that you typedef the function pointer into something more readable. For example.

typedef void (*functiontype)();

Declares a function that returns void and takes no arguments. To create a function pointer to this type you can now do:

void dosomething() { }

functiontype func = &dosomething;
func();

For a function that returns an int and takes a char you would do

typedef int (*functiontype2)(char);

and to use it

int dosomethingwithchar(char a) { return 1; }

functiontype2 func2 = &dosomethingwithchar
int result = func2('a');

There are libraries that can help with turning function pointers into nice readable types. The boost function library is great and is well worth the effort!

boost::function<int (char a)> functiontype2;

is so much nicer than the above.

If you want to output large quantities of HTML you should consider using heredoc or nowdoc syntax. This will allow you to write your strings without the need for escaping.

echo <<<EOD
You can put "s and 's here if you like.
EOD;

Also note that because PHP is an embedded language you can add it between you HTML content and you don't need to echo any tags.

<div>
    <p>No PHP here!</p>
    <?php
    $name = "Marcel";
    echo "<p>Hello $name!</p>";
    ?>
</div>

Also if you just want to output a variable you should use the short-hand output tags <?=$var?>. This is equivalent to <?php echo $var; ?>.

On PHP 5.3 this works for me:

if(!strlen(session_id())){
    session_name('someSpecialName');
    session_start();
} 

then you have. If you do not put the not at if statement beginning the session will start any way I do not why.

Ensure the browser and editor are using UTF-8 encoding instead of ISO-8859-1/Windows-1252.

Or use ’.
