Go to preferences(settings) : click on Build,Execution,Deployment .....then select : Instant Run ......and uncheck its topmost checkbox (i.e Disable Instant Run)

I fixed the ERROR with three steps
1. I checked for the problem SOURCE
2. Provided the correct string/text, because it was the CAUSE
3. I cleaned the project, you ll see it under BUILD.

I was suffering the same problem I solved it by checking build tab and switch to text mode. Check the console it will show the problems mine was removing a drawable without deleting the usage and deleting a class without deleting the usage also Text mode button

I have disabled Instant Run feature from the preferences and the issue was solved.

In DefaultConfig Add multiDexEnabled = true

    defaultConfig {
    applicationId "com.test"
    minSdkVersion 16
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    multiDexEnabled = true
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

Kotlin DSL: add to your build.gradle.kts

tasks.withType<Test> {
        useJUnitPlatform()
}

Gradle DSL: add to your build.gradle

test {
    useJUnitPlatform()
}

I was also stuck by this problem.But in my case I delete all .png images from drawable folder ,clean and rebuild application and then paste all .png images to my drawable, rebuild again. It worked fine for me.

I came across similar problem ,when I run

cordova build android

which report errors:

 /home/app/phonegap/helloworld/platforms/android/AndroidManifest.xml:15:5 Error:

There are some more actions you should consider:

• Remove Registry Entries for MS Distributed Transaction Coordinator (MSDTC)

  Note: on the Internet I found this step only at a single (private) page. I don't know if it is required/working or if it breaks anything on your PC.

  • Open Regedit
  • Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\MSDTC\MTxOCI
  • Add an x before each string for OracleOciLib, OracleSqlLib, and OracleXaLib
  • Navigate to HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\MSDTC\MTxOCI
  • Add an x before each string for OracleOciLib, OracleSqlLib, and OracleXaLib

  Otherwise these files, if they exist, will still be in use next time you reboot, and unable to be deleted.

• Remove environment variable ORACLE_HOME, ORACLE_BASE, TNS_ADMIN, NLS_LANG if exist

  Check also Oracle doc to find all Oracle related environment variables, however apart from variables listed above they are very rarely used on Windows Client: Oracle Environment Variables

• Unregister oci.dll

  • Open a command line window (Start Menu -> Run... -> cmd)

  • Enter regsvr32 /u oci.dll, resp. %windir%\SysWOW64\regsvr32 /u oci.dll

  • In some cases the file %ORACLE_HOME%\bin\oci.dll is locked and you cannot delete it. In such case rename the file (e.g. to oci.dll.x) and reboot the PC, afterwards you can delete it.

• Remove Oracle .NET assemblies from Global Assembly Cache (GAC). You do this typically with the gacutil utility, if available on your system. Would be like this:

  gacutil /u Policy.10.1.Oracle.DataAccess
  gacutil /u Policy.10.2.Oracle.DataAccess
  gacutil /u Policy.1.102.Oracle.DataAccess
  gacutil /u Policy.1.111.Oracle.DataAccess
  
  gacutil /u Policy.2.102.Oracle.DataAccess
  gacutil /u Policy.2.111.Oracle.DataAccess
  gacutil /u Policy.2.112.Oracle.DataAccess
  gacutil /u Policy.2.121.Oracle.DataAccess
  gacutil /u Policy.2.122.Oracle.DataAccess
  
  gacutil /u Policy.4.112.Oracle.DataAccess
  gacutil /u Policy.4.121.Oracle.DataAccess
  gacutil /u Policy.4.122.Oracle.DataAccess
  
  gacutil /u Oracle.DataAccess
  gacutil /u Oracle.DataAccess.resources
  
  gacutil /u Policy.4.121.Oracle.ManagedDataAccess
  gacutil /u Policy.4.122.Oracle.ManagedDataAccess
  gacutil /u Oracle.ManagedDataAccess
  gacutil /u Oracle.ManagedDataAccess.resources
  gacutil /u Oracle.ManagedDataAccessDTC
  gacutil /u Oracle.ManagedDataAccessIOP
  gacutil /u Oracle.ManagedDataAccess.EntityFramework
  

  • Entry System.Data.OracleClient should not be removed, this one is installed by Microsoft - not an Oracle component!

  • Instead of gacutil /u ... you can also use OraProvCfg /action:ungac /providerpath:... if OraProvCfg is still available on your system. You may find it at %ORACLE_HOME%\odp.net\managed\x64\OraProvCfg.exe.

• With a text editor, open XML Config file %SYSTEMROOT%\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config and delete branch <oracle.manageddataaccess.client>, if existing.

  • Do the same with:

    %SYSTEMROOT%\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config
    %SYSTEMROOT%\Microsoft.NET\Framework\v4.0.30319\Config\machine.config
    %SYSTEMROOT%\Microsoft.NET\Framework64\v4.0.30319\Config\web.config
    %SYSTEMROOT%\Microsoft.NET\Framework\v4.0.30319\Config\web.config
    

  Instead of editing the XML Config file manually you can also run (if OraProvCfg.exe is still available on your system):

  %ORACLE_HOME%\odp.net\managed\x64\OraProvCfg.exe /action:unconfig /product:odpm /frameworkversion:v4.0.30319 
  %ORACLE_HOME%\odp.net\managed\x86\OraProvCfg.exe /action:unconfig /product:odpm /frameworkversion:v4.0.30319
  %ORACLE_HOME%\odp.net\managed\x64\OraProvCfg.exe /action:unconfig /product:odp /frameworkversion:v4.0.30319 
  %ORACLE_HOME%\odp.net\managed\x86\OraProvCfg.exe /action:unconfig /product:odp /frameworkversion:v4.0.30319
  

• Check following Registry Keys and delete them if existing

  HKLM\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v2.0.50727\AssemblyFoldersEx\ODP.Net
  HKLM\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319\AssemblyFoldersEx\ODP.Net

• Delete the Inventory folder, typically C:\Program Files\Oracle\Inventory and C:\Program Files (x86)\Oracle\Inventory

• Delete temp folders %TEMP%\deinstall\, %TEMP%\OraInstall\ and %TEMP%\CVU* (e.g %TEMP%\CVU_11.1.0.2.0_domscheit) if existing.

It would be interesting to know the values supplied for the two ? placeholders.

In VB its normally Dir to find the directory of the file. If it's not blank then it exists and then use Kill to get rid of the file.

test = Dir(Filename)
If Not test = "" Then
    Kill (Filename)

Loading a python3 generated *.pyc file with python2 also causes this error.

This code works even faster (two 1.5 faster than my previous version):

    public List<String> GetUserGroups(WindowsIdentity identity)
    {
        List<String> groups = new List<String>();

        String userName = identity.Name;
        int pos = userName.IndexOf(@"\");
        if (pos > 0) userName = userName.Substring(pos + 1);

        PrincipalContext domain = new PrincipalContext(ContextType.Domain, "riomc.com");
        UserPrincipal user = UserPrincipal.FindByIdentity(domain, IdentityType.SamAccountName, userName); // NGeodakov

        DirectoryEntry de = new DirectoryEntry("LDAP://RIOMC.com");
        DirectorySearcher search = new DirectorySearcher(de);
        search.Filter = "(&(objectClass=group)(member=" + user.DistinguishedName + "))";
        search.PropertiesToLoad.Add("cn");
        search.PropertiesToLoad.Add("samaccountname");
        search.PropertiesToLoad.Add("memberOf");

        SearchResultCollection results = search.FindAll();
        foreach (SearchResult sr in results)
        {
            GetUserGroupsRecursive(groups, sr, de);
        }

        return groups;
    }

    public void GetUserGroupsRecursive(List<String> groups, SearchResult sr, DirectoryEntry de)
    {
        if (sr == null) return;

        String group = (String)sr.Properties["cn"][0];
        if (String.IsNullOrEmpty(group))
        {
            group = (String)sr.Properties["samaccountname"][0];
        }
        if (!groups.Contains(group))
        {
            groups.Add(group);
        }

        DirectorySearcher search;
        SearchResult sr1;
        String name;
        int equalsIndex, commaIndex;
        foreach (String dn in sr.Properties["memberof"])
        {
            equalsIndex = dn.IndexOf("=", 1);
            if (equalsIndex > 0)
            {
                commaIndex = dn.IndexOf(",", equalsIndex + 1);
                name = dn.Substring(equalsIndex + 1, commaIndex - equalsIndex - 1);

                search = new DirectorySearcher(de);

                search.PropertiesToLoad.Add("cn");
                search.PropertiesToLoad.Add("samaccountname");

                sr1 = search.FindOne();
                GetUserGroupsRecursive(groups, sr1, de);
            }
        }
    }

When define some member variable outside any member method, the variable can be either static or non-static depending on how the variable is expressed.

• CLASSNAME.var is static variable
• INSTANCENAME.var is not static variable.
• self.var inside class is not static variable.
• var inside the class member function is not defined.

For example:

#!/usr/bin/python

class A:
    var=1

    def printvar(self):
        print "self.var is %d" % self.var
        print "A.var is %d" % A.var


    a = A()
    a.var = 2
    a.printvar()

    A.var = 3
    a.printvar()

The results are

self.var is 2
A.var is 1
self.var is 2
A.var is 3

In the case where the process was spawned by another node process, like:

var child = spawn('gulp', ['watch'], {
    stdio: 'inherit',
});

And you try to kill it later, via:

child.kill();

This is how you handle the event [on the child]:

process.on('SIGTERM', function() {
    console.log('Goodbye!');
});

You need to change your code as below:

<html>
<body>

<span id="span_Id">Click the button to display the content.</span>

<button onclick="displayDate()">Click Me</button>

<script>
function displayDate() {
   var span_Text = document.getElementById("span_Id").innerText;
   alert (span_Text);
}
</script>
</body>
</html>

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

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

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

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

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

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

Yes, you can achieve it by find_elements_by_css_selector("*") or find_elements_by_xpath(".//*").

However, this doesn't sound like a valid use case to find all children of an element. It is an expensive operation to get all direct/indirect children. Please further explain what you are trying to do. There should be a better way.

from selenium import webdriver

driver = webdriver.Firefox()
driver.get("http://www.stackoverflow.com")

header = driver.find_element_by_id("header")

# start from your target element, here for example, "header"
all_children_by_css = header.find_elements_by_css_selector("*")
all_children_by_xpath = header.find_elements_by_xpath(".//*")

print 'len(all_children_by_css): ' + str(len(all_children_by_css))
print 'len(all_children_by_xpath): ' + str(len(all_children_by_xpath))

Without any external tool you can simply accomplish this on Windows 7 or 8, by opening up the Resource monitor and on the CPU or Overview tab right clicking on the process and selecting Suspend Process. The Resource monitor can be started from the Performance tab of the Task manager.

for (Map.Entry<String, ArrayList<Integer>> entry : map.entrySet()) {
 System.out.println( entry.getKey());     
 System.out.println( entry.getValue());//Returns the list of values
}

on the main.dart file import service like follow

  import 'package:flutter/services.dart';

and inside build method just add this line before return

SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
    statusBarColor: Colors.orange
)); 

Like this:

@override
 Widget build(BuildContext context) {
   SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
       statusBarColor: CustomColors.appbarcolor
    ));
    return MaterialApp(
    home: MySplash(),
    theme: ThemeData(
      brightness: Brightness.light,
      primaryColor: CustomColors.appbarcolor,
    ),
  );
 }

I came up with 4 methods to achieve the results. Here is demo

Method 1:

#a {
    margin-right: auto;
}

Method 2:

#a {
    flex-grow: 1;
}

Method 3:

#b {
    margin-left: auto;
}

Method 4:

#container {
    justify-content: space-between;
}

What worked for me is inserting a column before the first column and deleting it immediately. Basically, do a change that will affect all the cells in the worksheet that will trigger recalculation.

Generally speaking:

all and any are functions that take some iterable and return True, if

• in the case of all(), no values in the iterable are falsy;
• in the case of any(), at least one value is truthy.

A value x is falsy iff bool(x) == False. A value x is truthy iff bool(x) == True.

Any non-booleans in the iterable will be fine — bool(x) will coerce any x according to these rules: 0, 0.0, None, [], (), [], set(), and other empty collections will yield False, anything else True. The docstring for bool uses the terms 'true'/'false' for 'truthy'/'falsy', and True/False for the concrete boolean values.

In your specific code samples:

You misunderstood a little bit how these functions work. Hence, the following does something completely not what you thought:

if any(foobars) == big_foobar:

...because any(foobars) would first be evaluated to either True or False, and then that boolean value would be compared to big_foobar, which generally always gives you False (unless big_foobar coincidentally happened to be the same boolean value).

Note: the iterable can be a list, but it can also be a generator/generator expression (˜ lazily evaluated/generated list) or any other iterator.

What you want instead is:

if any(x == big_foobar for x in foobars):

which basically first constructs an iterable that yields a sequence of booleans—for each item in foobars, it compares the item to big_foobar and emits the resulting boolean into the resulting sequence:

tmp = (x == big_foobar for x in foobars)

then any walks over all items in tmp and returns True as soon as it finds the first truthy element. It's as if you did the following:

In [1]: foobars = ['big', 'small', 'medium', 'nice', 'ugly']                                        

In [2]: big_foobar = 'big'                                                                          

In [3]: any(['big' == big_foobar, 'small' == big_foobar, 'medium' == big_foobar, 'nice' == big_foobar, 'ugly' == big_foobar])        
Out[3]: True

Note: As DSM pointed out, any(x == y for x in xs) is equivalent to y in xs but the latter is more readable, quicker to write and runs faster.

Some examples:

In [1]: any(x > 5 for x in range(4))
Out[1]: False

In [2]: all(isinstance(x, int) for x in range(10))
Out[2]: True

In [3]: any(x == 'Erik' for x in ['Erik', 'John', 'Jane', 'Jim'])
Out[3]: True

In [4]: all([True, True, True, False, True])
Out[4]: False

If you have format dd-mm-yyyy then in PHP it won't work as expected. In PHP document they have below guideline.

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

So, you just can't use as you wish. When your try to use dd/mm/yyyy format with this then it will remove FALSE. You can tweak with the following.

$date = "23/02/2013";
$timestamp = strtotime($date);
if ($timestamp === FALSE) {
  $timestamp = strtotime(str_replace('/', '-', $date));
}
echo $timestamp; // prints 1361577600

When using the Hibernate implementation of JPA , I've found that simply declaring the type as an ArrayList instead of List allows hibernate to store the list of data.

Clearly this has a number of disadvantages compared to creating a list of Entity objects. No lazy loading, no ability to reference the entities in the list from other objects, perhaps more difficulty in constructing database queries. However when you are dealing with lists of fairly primitive types that you will always want to eagerly fetch along with the entity, then this approach seems fine to me.

@Entity
public class Command implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    Long id;

    ArrayList<String> arguments = new ArrayList<String>();


}

You can use the new request method getSchemeAndHttpHost():

{{ app.request.getSchemeAndHttpHost() }}

Note that if you are using Java 5 or newer, you should use StringBuilder instead of StringBuffer. From the API documentation:

As of release JDK 5, this class has been supplemented with an equivalent class designed for use by a single thread, StringBuilder. The StringBuilder class should generally be used in preference to this one, as it supports all of the same operations but it is faster, as it performs no synchronization.

In practice, you will almost never use this from multiple threads at the same time, so the synchronization that StringBuffer does is almost always unnecessary overhead.

I've been trying to copy a table from PROD to DEV but get an error: "Cannot find the object X because it does not exist or you do not have permissions."

However, the table did exist, and I was running as sa so I did have permissions.

The problem was actually with CONTRAINTS. I'd renamed the table on DEV to be old_XXX months ago. But when I tried to copy the original one over from PROD, the Defaut Constraint names clashed.

The error message was misleading

I was able to resolve this problem by cleaning my assets cache:

$ rake assets:clean

I also had the same problem with this but on Windows after upgrading to MySQL 5.5 from MySQL 5.1. I already tried changing, creating, and resetting password mentioned in here, here, here, and here, no clue. I still get the same error:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

I'm able to connect normally, show all databases, do selects and inserts, create and add users, and but when it comes to GRANT, I'm screwed up. Those access denied error shows up again.

I managed to solve this problem by fixing the privileges by the following command on the MySQL server bin/ directory as mentioned in here:

C:\MySQL Server 5.5\bin> mysql_upgrade

Then, the problem gone away. I hope this solution works on Linux too since usually MySQL provide the same command both on Linux and Windows.

For JSF Application

To get resource bundle prop files from a given file path to use them in a JSF app.

• Set the bundle with URLClassLoader for a class that extends ResourceBundle to load the bundle from the file path.
• Specify the class at basename property of loadBundle tag. <f:loadBundle basename="Message" var="msg" />

For basic implementation of extended RB please see the sample at Sample Customized Resource Bundle

/* Create this class to make it base class for Loading Bundle for JSF apps */
public class Message extends ResourceBundle {
        public Messages (){
                File file = new File("D:\\properties\\i18n");  
                ClassLoader loader=null;
                   try {
                       URL[] urls = {file.toURI().toURL()};  
                       loader = new URLClassLoader(urls); 
                       ResourceBundle bundle = getBundle("message", FacesContext.getCurrentInstance().getViewRoot().getLocale(), loader);
                       setParent(bundle);
                       } catch (MalformedURLException ex) { }
       }
      .
      .
      .
    }

Otherwise, get the bundle from getBundle method but locale from others source like Locale.getDefault(), the new (RB)class may not require in this case.

1. Modify the definition of the function check_me as::

    function check_me(ev) {
   

2. Now you can access the methods and parameters of the event, in your case:

    ev.preventDefault();
   

3. Then, you have to pass the parameter on the onclick in the inline call::

    <button type="button" onclick="check_me(event);">Click Me!</button>
   

A useful link to understand this.

Full example:

<!DOCTYPE html>
<html lang="en">
  <head>
    <script type="text/javascript">
      function check_me(ev) {
        ev.preventDefault();
        alert("Hello World!")
      }
    </script>
  </head>
  <body>
    <button type="button" onclick="check_me(event);">Click Me!</button>
  </body>
</html>

Alternatives (best practices):

Although the above is the direct answer to the question (passing an event object to an inline event), there are other ways of handling events that keep the logic separated from the presentation

A. Using addEventListener:

<!DOCTYPE html>
<html lang="en">
  <head>
  </head>
  <body>
    <button id='my_button' type="button">Click Me!</button>

    <!-- put the javascript at the end to guarantee that the DOM is ready to use-->
    <script type="text/javascript">
      function check_me(ev) {
        ev.preventDefault();
        alert("Hello World!")
      }
      
      <!-- add the event to the button identified #my_button -->
      document.getElementById("my_button").addEventListener("click", check_me);
    </script>
  </body>
</html>

B. Isolating Javascript:

Both of the above solutions are fine for a small project, or a hackish quick and dirty solution, but for bigger projects, it is better to keep the HTML separated from the Javascript.

Just put this two files in the same folder:

• example.html:

<!DOCTYPE html>
<html lang="en">
  <head>
  </head>
  <body>
    <button id='my_button' type="button">Click Me!</button>

    <!-- put the javascript at the end to guarantee that the DOM is ready to use-->
    <script type="text/javascript" src="example.js"></script>
  </body>
</html>

• example.js:

function check_me(ev) {
    ev.preventDefault();
    alert("Hello World!")
}
document.getElementById("my_button").addEventListener("click", check_me);

It's 2019 and you should be using this:

let arr = [...Array(20)].fill(10)

So basically 20 is the length or a new instantiated Array.

This following solution worked for me. In the following configuration file:

C:\Users\<user>\.android\avd\<avd-profile-name>.avd\config.ini

Replace

hw.ramSize=1024

by

hw.ramSize=1024MB

SELECT column_Name1,column_name2,......
  From tbl_name1,tbl_name2,tbl_name3
  where tbl_name1.column_name = tbl_name2.column_name 
  and tbl_name2.column_name = tbl_name3.column_name

Its strange that such a simple setting would require this amount of 'hocus-pocus' to work.

To answer your question now, for me it seemed to work with the combination of the following:

:set wrap linebreak nolist

(this seems to prevent existing lines from breaking, just wrap.)

AND

set formatoptions=l

(this prevents new/edited lines from breaking, while += does not do it for me as other settings/plugins seem to find space and add their own options which override mine.)

Use a DateFormat implementation; e.g. SimpleDateFormat.

DateFormat df = new SimpleDateFormat("dd/MM/yyyy");
String data = df.format(new Date());

Be very careful with Collections2.transform() from guava. That method's greatest advantage is also its greatest danger: its laziness.

Look at the documentation of Lists.transform(), which I believe applies also to Collections2.transform():

The function is applied lazily, invoked when needed. This is necessary for the returned list to be a view, but it means that the function will be applied many times for bulk operations like List.contains(java.lang.Object) and List.hashCode(). For this to perform well, function should be fast. To avoid lazy evaluation when the returned list doesn't need to be a view, copy the returned list into a new list of your choosing.

Also in the documentation of Collections2.transform() they mention you get a live view, that change in the source list affect the transformed list. This sort of behaviour can lead to difficult-to-track problems if the developer doesn't realize the way it works.

If you want a more classical "map", that will run once and once only, then you're better off with FluentIterable, also from Guava, which has an operation which is much more simple. Here is the google example for it:

FluentIterable
       .from(database.getClientList())
       .filter(activeInLastMonth())
       .transform(Functions.toStringFunction())
       .limit(10)
       .toList();

transform() here is the map method. It uses the same Function<> "callbacks" as Collections.transform(). The list you get back is read-only though, use copyInto() to get a read-write list.

Otherwise of course when java8 comes out with lambdas, this will be obsolete.

If another pull just works, it means your internet wasn't connected.

It looks like data not contains what you think it contains - check it.

let data={"name": "", "skills": "", "jobtitel": "Entwickler", "res_linkedin": "GwebSearch"};_x000D_
_x000D_
console.log( data["jobtitel"] );_x000D_
console.log( data.jobtitel );

Tilde (~)

major version is fixed, minor version is fixed, matches any build number

"express": "~4.13.3" 

~4.13.3 means it will check for 4.13.x where x is anything and 4.14.0

Caret (^)

major version is fixed, matches any minor version, matches any build number

"supertest": "^3.0.0"

^3.0.0 means it will check for 3.x.x where x is anything

You don't have to track whether you've already changed the character from upper to lower. Your code is already doing that since it's basically:

1   for each character x:
2       if x is uppercase:
3           convert x to lowercase
4       else:
5           if x is lowercase:
6                convert x to uppercase.

The fact that you have that else in there (on line 4) means that a character that was initially uppercase will never be checked in the second if statement (on line 5).

Example, start with A. Because that's uppercase, it will be converted to lowercase on line 3 and then you'll go back up to line 1 for the next character.

If you start with z, the if on line 2 will send you directly to line 5 where it will be converted to uppercase. Anything that's neither upper nor lowercase will fail both if statements and therefore remain untouched.

Your composer.phar must be in Source files. I had same problem and I just cut my composer.phar into mine framework-standard-edition folder, where is my whole strong textproject.

The popular hashing methods used are not really very good for large sets and, as pointed out above, the hash used is particularly bad. Better is to use a hash algorithm with high mixing and coverage such as BuzHash (sample implementation at http://www.java2s.com/Code/Java/Development-Class/AveryefficientjavahashalgorithmbasedontheBuzHashalgoritm.htm)

Insert your fetched values into an array instead of echoing.

Use file_put_contents() and insert json_encode($rows) into that file, if $rows is your data.

:goto 21490 will take you to the 21490th byte in the buffer.

In Swift 3.0

let screenSize = UIScreen.main.bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height

In older swift: Do something like this:

let screenSize: CGRect = UIScreen.mainScreen().bounds

then you can access the width and height like this:

let screenWidth = screenSize.width
let screenHeight = screenSize.height

if you want 75% of your screen's width you can go:

let screenWidth = screenSize.width * 0.75

Swift 4.0

// Screen width.
public var screenWidth: CGFloat {
    return UIScreen.main.bounds.width
}

// Screen height.
public var screenHeight: CGFloat {
    return UIScreen.main.bounds.height
}

In Swift 5.0

let screenSize: CGRect = UIScreen.main.bounds

I'm not content with HTML/CSS-only solutions, so I've decided to create a custom select using JavaScript.

This is something I've written in the past 30 mins, thus it can be further improved.

All you have to do is create a simple list with few data attributes. The code automatically turns the list into a selectable dropdown. It also adds a hidden input to hold the selected value, so it can be used in a form.

Input:

<ul class="select" data-placeholder="Role" data-name="role">
  <li data-value="admin">Administrator</li>
  <li data-value="mod">Moderator</li>
  <li data-value="user">User</li>
</ul>

Output:

<div class="ul-select-container">
    <input type="hidden" name="role" class="hidden">
    <div class="selected placeholder">
        <span class="text">Role</span>
        <span class="icon">?</span>
    </div>
    <ul class="select" data-placeholder="Role" data-name="role">
        <li class="placeholder">Role</li>
        <li data-value="admin">Administrator</li>
        <li data-value="mod">Moderator</li>
        <li data-value="user">User</li>
    </ul>
</div>

The text of the item that's supposed to be a placeholder is grayed out. The placeholder is selectable, in case the user wants to revert his/her choice. Also using CSS, all the drawbacks of select can be overcome (e.g., inability of the styling of the options).

1. SOAP Web Services are standard-based and supported by almost every software platform: They rely heavily in XML and have support for transactions, security, asynchronous messages and many other issues. It’s a pretty big and complicated standard, but covers almost every messaging situation. On the other side, RESTful services relies of HTTP protocol and verbs (GET, POST, PUT, DELETE) to interchange messages in any format, preferable JSON and XML. It’s a pretty simple and elegant architectural approach.
2. As in every topic in the Java World, there are several libraries to build/consume Web Services. In the SOAP Side you have the JAX-WS standard and Apache Axis, and in REST you can use Restlets or Spring REST Facilities among other libraries.

With question 3, this article states that RESTful Services are appropiate in this scenarios:

• If you have limited bandwidth
• If your operations are stateless: No information is preserved from one invocation to the next one, and each request is treated independently.
• If your clients require caching.

While SOAP is the way to go when:

• If you require asynchronous processing
• If you need formal contract/Interfaces
• In your service operations are stateful: For example, you store information/data on a request and use that stored data on the next one.

SELECT *
FROM A.tableA JOIN B.tableB 

or

SELECT *
  FROM A.tableA JOIN B.tableB
  ON A.tableA.id = B.tableB.a_id;

We could do it with jQuery:

$(window).resize(function(){
    alert(window.innerWidth);

    $scope.$apply(function(){
       //do something to update current scope based on the new innerWidth and let angular update the view.
    });
});

Be aware that when you bind an event handler inside scopes that could be recreated (like ng-repeat scopes, directive scopes,..), you should unbind your event handler when the scope is destroyed. If you don't do this, everytime when the scope is recreated (the controller is rerun), there will be 1 more handler added causing unexpected behavior and leaking.

In this case, you may need to identify your attached handler:

  $(window).on("resize.doResize", function (){
      alert(window.innerWidth);

      $scope.$apply(function(){
          //do something to update current scope based on the new innerWidth and let angular update the view.
      });
  });

  $scope.$on("$destroy",function (){
      $(window).off("resize.doResize"); //remove the handler added earlier
  });

In this example, I'm using event namespace from jQuery. You could do it differently according to your requirements.

Improvement: If your event handler takes a bit long time to process, to avoid the problem that the user may keep resizing the window, causing the event handlers to be run many times, we could consider throttling the function. If you use underscore, you can try:

$(window).on("resize.doResize", _.throttle(function (){
    alert(window.innerWidth);

    $scope.$apply(function(){
        //do something to update current scope based on the new innerWidth and let angular update the view.
    });
},100));

or debouncing the function:

$(window).on("resize.doResize", _.debounce(function (){
     alert(window.innerWidth);

     $scope.$apply(function(){
         //do something to update current scope based on the new innerWidth and let angular update the view.
     });
},100));

Difference Between throttling and debouncing a function

It is quite easy using width: 70%; left:15%;

Sets the element width to 70% of the window and leaves 15% on both sides

The first one

f = lambda x: x*x
[f(x) for x in range(10)]

runs f() for each value in the range so it does f(x) for each value

the second one

[lambda x: x*x for x in range(10)]

runs the lambda for each value in the list, so it generates all of those functions.

copy structure in c you just need to assign the values as follow:

struct RTCclk RTCclk1;
struct RTCclk RTCclkBuffert;

RTCclk1.second=3;
RTCclk1.minute=4;
RTCclk1.hour=5;

RTCclkBuffert=RTCclk1;

now RTCclkBuffert.hour will have value 5,

RTCclkBuffert.minute will have value 4

RTCclkBuffert.second will have value 3

Just to add to answers above, you can streamline the use of express-fileupload to just a single route that needs it, instead of adding it to the every route.

let fileupload = require("express-fileupload");

...

app.post("/upload", fileupload, function(req, res){

...

});

I'm sure it is executing properly, but you're trying to change the UI elements in the background thread and that won't do.

Revise your call and AsyncTask as follows:

Calling Class

Note: I personally suggest using onPostExecute() wherever you execute your AsyncTask thread and not in the class that extends AsyncTask itself. I think it makes the code easier to read especially if you need the AsyncTask in multiple places handling the results slightly different.

new LongThread() {
    @Override public void onPostExecute(String result) {
        TextView txt = (TextView) findViewById(R.id.output);
        txt.setText(result);
    }
}.execute("");

LongThread class (extends AsyncTask):

@Override
protected String doInBackground(String... params) {
    for (int i = 0; i < 5; i++) {
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

    return "Executed";
}      

The problem is that readlines is a list of strings, each of which is a line of filename. Perhaps you meant:

for line in readlines:
    Type = line.split(",")
    x = Type[1]
    y = Type[2]
    print(x,y)

Note that the answer from @unutbu will be correct until you want to set the value to something new, then it will not work if your dataframe is a view.

There are a few existing resources you might check:

1. Properly Package Your Java Classes
2. Spring 2.5 Architecture
3. Java Tutorial - Naming a Package
4. SUN Naming Conventions

For what it's worth, my own personal guidelines that I tend to use are as follows:

1. Start with reverse domain, e.g. "com.mycompany".
2. Use product name, e.g. "myproduct". In some cases I tend to have common packages that do not belong to a particular product. These would end up categorized according to the functionality of these common classes, e.g. "io", "util", "ui", etc.
3. After this it becomes more free-form. Usually I group according to project, area of functionality, deployment, etc. For example I might have "project1", "project2", "ui", "client", etc.

A couple of other points:

1. It's quite common in projects I've worked on for package names to flow from the design documentation. Usually products are separated into areas of functionality or purpose already.
2. Don't stress too much about pushing common functionality into higher packages right away. Wait for there to be a need across projects, products, etc., and then refactor.
3. Watch inter-package dependencies. They're not all bad, but it can signify tight coupling between what might be separate units. There are tools that can help you keep track of this.

You can try the trim() method.

String newString = oldString.trim();

Take a look at javadocs

Gilean's answer is great, but I just wanted to add that sometimes there are rare exceptions to best practices, and you might want to test your environment both ways to see what will work best.

In one case, I found that query worked faster for my purposes because I was bulk transferring trusted data from an Ubuntu Linux box running PHP7 with the poorly supported Microsoft ODBC driver for MS SQL Server.

I arrived at this question because I had a long running script for an ETL that I was trying to squeeze for speed. It seemed intuitive to me that query could be faster than prepare & execute because it was calling only one function instead of two. The parameter binding operation provides excellent protection, but it might be expensive and possibly avoided if unnecessary.

Given a couple rare conditions:

1. If you can't reuse a prepared statement because it's not supported by the Microsoft ODBC driver.

2. If you're not worried about sanitizing input and simple escaping is acceptable. This may be the case because binding certain datatypes isn't supported by the Microsoft ODBC driver.

3. PDO::lastInsertId is not supported by the Microsoft ODBC driver.

Here's a method I used to test my environment, and hopefully you can replicate it or something better in yours:

To start, I've created a basic table in Microsoft SQL Server

CREATE TABLE performancetest (
    sid INT IDENTITY PRIMARY KEY,
    id INT,
    val VARCHAR(100)
);

And now a basic timed test for performance metrics.

$logs = [];

$test = function (String $type, Int $count = 3000) use ($pdo, &$logs) {
    $start = microtime(true);
    $i = 0;
    while ($i < $count) {
        $sql = "INSERT INTO performancetest (id, val) OUTPUT INSERTED.sid VALUES ($i,'value $i')";
        if ($type === 'query') {
            $smt = $pdo->query($sql);
        } else {
            $smt = $pdo->prepare($sql);
            $smt ->execute();
        }
        $sid = $smt->fetch(PDO::FETCH_ASSOC)['sid'];
        $i++;
    }
    $total = (microtime(true) - $start);
    $logs[$type] []= $total;
    echo "$total $type\n";
};

$trials = 15;
$i = 0;
while ($i < $trials) {
    if (random_int(0,1) === 0) {
        $test('query');
    } else {
        $test('prepare');
    }
    $i++;
}

foreach ($logs as $type => $log) {
    $total = 0;
    foreach ($log as $record) {
        $total += $record;
    }
    $count = count($log);
    echo "($count) $type Average: ".$total/$count.PHP_EOL;
}

I've played with multiple different trial and counts in my specific environment, and consistently get between 20-30% faster results with query than prepare/execute

5.8128969669342 prepare
5.8688418865204 prepare

(7) prepare Average: 6.0673267160143
(8) query Average: 4.3276024162769

I'm curious to see how this test compares in other environments, like MySQL.

right click -> build path -> remove from build path and then again add it -> Right click on the folder named 'Test' > Build Path > Use as Source Folder.

Since version 3.3 of ggplot2, we have access to the convenient after_stat() function.

We can do something similar to @Andrew's answer, but without using the .. syntax:

# original example data
mydata <- c("aa", "bb", NULL, "bb", "cc", "aa", "aa", "aa", "ee", NULL, "cc")

# display percentages
library(ggplot2)
ggplot(mapping = aes(x = mydata,
                     y = after_stat(count/sum(count)))) +
  geom_bar() +
  scale_y_continuous(labels = scales::percent)

You can find all the "computed variables" available to use in the documentation of the geom_ and stat_ functions. For example, for geom_bar(), you can access the count and prop variables. (See the documentation for computed variables.)

One comment about your NULL values: they are ignored when you create the vector (i.e. you end up with a vector of length 9, not 11). If you really want to keep track of missing data, you will have to use NA instead (ggplot2 will put NAs at the right end of the plot):

# use NA instead of NULL
mydata <- c("aa", "bb", NA, "bb", "cc", "aa", "aa", "aa", "ee", NA, "cc")
length(mydata)
#> [1] 11

# display percentages
library(ggplot2)
ggplot(mapping = aes(x = mydata,
                     y = after_stat(count/sum(count)))) +
  geom_bar() +
  scale_y_continuous(labels = scales::percent)

(Note that using chr or fct data will not make a difference for your example.)

sleep 6 will sleep for 6 seconds. For a longer duration, you can also use sleep(6.minutes) or sleep(6.hours).

try this if you want your radio button to be checked based on value of some variable e.g. "genderStr" then you can use following code snippet

    if(genderStr.equals("Male"))
       genderRG.check(R.id.maleRB);
    else 
       genderRG.check(R.id.femaleRB);

Basically set up your css like:

element {
  border: 1px solid #fff;      
  transition: border .5s linear;
}

element.saved {
  border: 1px solid transparent;
}

set your property using below code at the time of model creation i think your problem will be solved..and the time are not appear in database.you dont need to add any annotation.

private DateTime? dob;
        public DateTime? DOB
        {
            get
            {
                if (dob != null)
                {
                    return dob.Value.Date;
                }
                else
                {
                    return null;
                }

            }
            set { dob = value; }
        }

def get_domain(url):

    if hostname == '':
        # Force the recognition as a full URL
        hostname = urlparse.urlparse('http://' + uri).netloc

    # Remove the 'user:passw', 'www.' and ':port' parts
    hostname = hostname.split('@')[-1].split(':')[0].lstrip('www.').split('.')

    num_parts = len(hostname)
    if (num_parts < 3) or (len(hostname[-1]) > 2):
        return '.'.join(hostname[:-1])
    if len(hostname[-2]) > 2 and hostname[-2] not in GENERIC_TLDS:

This code isn't guaranteed to work with all URLs and doesn't filter those that are grammatically correct but invalid like 'example.uk'.

However it'll do the job in most cases.

Using React

I came across this error in my react profile app. My app behaved kind of like it was trying to reference a url that doesn't exist. I believe this has something to do with how webpack behaves.

If you are linking files in your public folder you must remember to use %PUBLIC_URL% before the resource like this:

<link type="text/css" rel="stylesheet" href="%PUBLIC_URL%/bootstrap.min.css" />

Here is how one can do it via the global request helper function.

{{ request()->segment(1) }}

Note: request() returns the object of the Request class.

POST and GET are two HTTP request methods. GET is usually intended to retrieve some data, and is expected to be idempotent (repeating the query does not have any side-effects) and can only send limited amounts of parameter data to the server. GET requests are often cached by default by some browsers if you are not careful.

POST is intended for changing the server state. It carries more data, and repeating the query is allowed (and often expected) to have side-effects such as creating two messages instead of one.

Given an object which I suspect to be some kind of IList<>, how can I determine of what it's an IList<>?

Here's a reliable solution. My apologies for length - C#'s introspection API makes this suprisingly difficult.

/// <summary>
/// Test if a type implements IList of T, and if so, determine T.
/// </summary>
public static bool TryListOfWhat(Type type, out Type innerType)
{
    Contract.Requires(type != null);

    var interfaceTest = new Func<Type, Type>(i => i.IsGenericType && i.GetGenericTypeDefinition() == typeof(IList<>) ? i.GetGenericArguments().Single() : null);

    innerType = interfaceTest(type);
    if (innerType != null)
    {
        return true;
    }

    foreach (var i in type.GetInterfaces())
    {
        innerType = interfaceTest(i);
        if (innerType != null)
        {
            return true;
        }
    }

    return false;
}

Example usage:

    object value = new ObservableCollection<int>();
Type innerType;
TryListOfWhat(value.GetType(), out innerType).Dump();
innerType.Dump();

Returns

True
typeof(Int32)

I did not know the answer so asked the ASP.NET team here.

So the trick is to change the signature to HttpResponseMessage and use Request.CreateResponse.

[ResponseType(typeof(User))]
public HttpResponseMessage GetUser(HttpRequestMessage request, int userId, DateTime lastModifiedAtClient)
{
    var user = new DataEntities().Users.First(p => p.Id == userId);
    if (user.LastModified <= lastModifiedAtClient)
    {
         return new HttpResponseMessage(HttpStatusCode.NotModified);
    }
    return request.CreateResponse(HttpStatusCode.OK, user);
}

What's the problem with using for loop inside, just like outside?

for (int j = i + 1; j < list.size(); ++j) {
    ...
}

In general, since Java 5, I used iterators only once or twice.

You can use AlarmManager in coop with notification mechanism Something like this:

Intent intent = new Intent(ctx, ReminderBroadcastReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(ctx, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager am = (AlarmManager) ctx.getSystemService(Activity.ALARM_SERVICE);
// time of of next reminder. Unix time.
long timeMs =...
if (Build.VERSION.SDK_INT < 19) {
    am.set(AlarmManager.RTC_WAKEUP, timeMs, pendingIntent);
} else {
    am.setExact(AlarmManager.RTC_WAKEUP, timeMs, pendingIntent);
}

It starts alarm.

public class ReminderBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
                .setSmallIcon(...)
                .setContentTitle(..)
                .setContentText(..);
        Intent intentToFire = new Intent(context, Activity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intentToFire, PendingIntent.FLAG_UPDATE_CURRENT);
        builder.setContentIntent(pendingIntent);
        NotificationManagerCompat.from(this);.notify((int) System.currentTimeMillis(), builder.build());
    }
}

I noticed that many examples are overcomplicated for localhost where just postgres user without password exist in many cases:

psql -d db_name -f dump.sql

Here is a VB.NET solution based on ShravankumarKumar's solution.

This will ONLY give you the text. The images are a different story.

Public Shared Function GetTextFromPDF(PdfFileName As String) As String
    Dim oReader As New iTextSharp.text.pdf.PdfReader(PdfFileName)

    Dim sOut = ""

    For i = 1 To oReader.NumberOfPages
        Dim its As New iTextSharp.text.pdf.parser.SimpleTextExtractionStrategy

        sOut &= iTextSharp.text.pdf.parser.PdfTextExtractor.GetTextFromPage(oReader, i, its)
    Next

    Return sOut
End Function

Seems there's an easier way, at least in Kendo UI v2015.2.624:

$('#myDropDownSelector').data('kendoDropDownList').search('Text value to find');

If there's not a match in the dropdown, Kendo appears to set the dropdown to an unselected value, which makes sense.

I couldn't get @Gang's answer to work, but if you swap his value with search, as above, we're golden.

Depends on your requirment, but the most effective way to create is:

 Product obj = new Product
            {
                ID = 21,
                Price = 200,
                Category = "XY",
                Name = "SKR",
            };

One way is to execute the following.

git clone user@git-server:project_name.git -b branch_name /your/folder

Where branch_name is the branch of your choice and "/your/folder" is the destination folder for that branch. It's true that this will bring other branches giving you the opportunity to merge back and forth.

Update

Now, starting with Git 1.7.10, you can now do this

git clone user@git-server:project_name.git -b branch_name --single-branch /your/folder

I know this is a somewhat old thread, but I had this problem too with a c#/WPF app I was creating. The app worked fine on the development machine, but would not start on the test machine. The Application Log in the Event Viewer gave a somewhat nebulous .NET Runtime error of System.IO.DirectoryNotFoundException.

I tried using some debugging software but the app would not stay running long enough to attach the debugger to the process. After banging my head against my desk for a day and looking at many web pages like this one, what I wound up doing to troubleshoot this was to install VS2019 on my test machine. I then dragged the .exe file from its folder (it was deep in the Users[user]\AppData\Apps\2.0... folder) to the open VS2019 instance and went to start it from there. Immediately, it came up with a dialog box giving the exception and the cause.

In my case, when I added an icon to one of the forms, the complete path to the icon was placed into the XAML instead of just the icon name. I had copied the icon file into the project folder, but since the project folder does not exist on the test machine, this was the root cause of the error. I then removed the path from the XAML, leaving just the icon name one, rebuilt the solution and re-published it, and it ran just fine on the test machine now. Of course there are many causes besides what gave me the error, but this method of troubleshooting should hopefully identify the root cause of the error, since the Windows Event Viewer gives a somewhat vague answer.

To summarize, use Visual Studio on the test machine as a debugger of sorts. But, to get it to work right, I had to drag the .exe file into the IDE and Start (run) it from there. I believe this will also work with VS2017 as well as VS2019. Hopefully this helps someone who is still having this issue.

I had this problem too on a win7 machine. I wanted to update the jre with a jdk. So i deleted the jre folder and downloaded and unzipped the new jdk. The issue was i manually deleted the jre folder, when instead i should've uninstalled it. This leaves a bunch of registry entries that still point to the old jre. Somehow eclipse still wants to use the old jre. I couldn't uninstall the old java vm, i kept getting this error:

Error 1723. There is a problem with this Windows Installer package. A DLL required for this install to complete could not be run. Contact your support personnel or package vendor

So i had to use this MS utility to fix the uninstall:

http://support.microsoft.com/kb/2438651/

Then i had to install again the vm. I installed to the same location the original one was at, to avoid losing another hour! After that eclipse started correctly.

The line in the theme style works fine, yet that replaces the animation with a white screen. Especially on a slower phone - it is really annoying. So, if you want an instant transition - you could use this in the theme style:

<item name="android:windowAnimationStyle">@null</item>
<item name="android:windowDisablePreview">true</item>

I get the same error in WP when I use php ver 7.1.6 - just take your php version back to 7.0.20 and the error will disappear.

The problem is that you're reading nextLine() on the while loop and THEN reading it to a variable. Not only are you getting every 2nd line printed out you're opening yourself to the exception being thrown. An example:

File:

Hello,
Blah blah blah,
Sincerely,
CapnStank
PS. Something something

On first iteration through the loop. The check on while will consume the "Hello," as not equal to null. Inside the loop body you'll see Blah blah blah, printed to the System.

The process will repeat with Sincerely, being consumed and Capnstank printing out.

Finally the while will consume the "PS" line while the String line = fileReader.nextLine() retreives an exception from the file because there's nothing further to read.

To resolve the issue:

String line = fileReader.nextLine();

while (line != null) {
  System.out.println(line);
  line = fileReader.nextLine();
}

I installed Python 3.5 by Software Collections on CentOS 7 minimal. It all worked fine on its own, but I saw the shared library error mentioned in this question when I tried running a simple CGI script:

tail /var/log/httpd/error_log
AH01215: /opt/rh/rh-python35/root/usr/bin/python: error while loading shared libraries: libpython3.5m.so.rh-python35-1.0: cannot open shared object file: No such file or directory

I wanted a systemwide permanent solution that works for all users, so that excluded adding export statements to .profile or .bashrc files. There is a one-line solution, based on the Red Hat solutions page. Thanks for the comment that points it out:

echo 'source scl_source enable rh-python35' | sudo tee --append /etc/profile.d/python35.sh

After a restart, it's all good on the shell, but sometimes my web server still complains. There's another approach that always worked for both the shell and the server, and is more generic. I saw the solution here and then realized it's actually mentioned in one of the answers here as well! Anyway, on CentOS 7, these are the steps:

 vim /etc/ld.so.conf

Which on my machine just had:

include ld.so.conf.d/*.conf

So I created a new file:

vim /etc/ld.so.conf.d/rh-python35.conf

And added:

/opt/rh/rh-python35/root/usr/lib64/

And to manually rebuild the cache:

sudo ldconfig

That's it, scripts work fine!

This was a temporary solution, which didn't work across reboots:

sudo ldconfig /opt/rh/rh-python35/root/usr/lib64/ -v

The -v (verbose) option was just to see what was going on. I saw that it did: /opt/rh/rh-python35/root/usr/lib64: libpython3.so.rh-python35 -> libpython3.so.rh-python35 libpython3.5m.so.rh-python35-1.0 -> libpython3.5m.so.rh-python35-1.0

This particular error went away. Incidentally, I had to chown the user to apache to get rid of a permission error after that.

Note that I used find to locate the directory for the library. You could also do:

sudo yum install mlocate
sudo updatedb
locate libpython3.5m.so.rh-python35-1.0

Which on my VM returns:

/opt/rh/rh-python35/root/usr/lib64/libpython3.5m.so.rh-python35-1.0

Which is the path I need to give to ldconfig, as shown above.

I have an application which I wanted to:

1. Send an email to the user
2. Exit with an error code

I had to hook process.exit(code) to an exit event handler, or else the mail will not be sent since calling process.exit(code) directly kills asynchronous events.

#!/usr/bin/nodejs
var mailer = require('nodemailer');
var transport = mailer.createTransport();
mail = {
  to: 'Dave Bowman',
  from: 'HAL 9000',
  subject: 'Sorry Dave',
  html: 'Im sorry, Dave. Im afraid I cant do <B>THAT</B>.'
}
transport.sendMail(mail);
//process.exit(1);
process.on('exit', function() { process.exit(1); });

You build the object before encoding it to a JSON string:

import json

data = {}
data['key'] = 'value'
json_data = json.dumps(data)

JSON is a serialization format, textual data representing a structure. It is not, itself, that structure.

Add the item first and then serialize:

$.ajax({
    type: 'POST',
    url: this.action,
    data: $.extend($(this), {'NonFormValue': NonFormValue}).serialize()
});

select CAST(DATEDIFF(MONTH, StartDate, EndDate) AS float) -
  (DATEPART(dd,StartDate) - 1.0) / DATEDIFF(DAY, StartDate, DATEADD(MONTH, 1, StartDate)) +

Below input field I include additional view:

@include('input-errors', ['inputName' => 'inputName']) #For your case it would be 'email'

input-errors.blade.php

@foreach ($errors->get($inputName) as $message)
    <span class="input-error">{{ $message }}</span>
@endforeach

CSS - adds red color to the message.

.input-error {
    color: #ff5555;
}

Here's a reusable solution: http://jsfiddle.net/flobar/r28b0gmq/

function accessScope(node, func) {
    var scope = angular.element(document.querySelector(node)).scope();
    scope.$apply(func);
}

window.onload = function () {

    accessScope('#outer', function (scope) {
        // change any property inside the scope
        scope.name = 'John';
        scope.sname = 'Doe';
        scope.msg = 'Superhero';
    });

};

You can try with the code that is below.

It will make the default date become the date you are looking for.

$('#birthdate').datepicker("setDate", new Date(1985,01,01) );

WebDriverWait wait = new WebDriverWait(driver,5)
wait.until(ExpectedConditions.visibilityOf(element));

you can use this as some time before loading whole page code gets executed and throws and error. time is in second

int temp = i;
while (temp >= 10)
{
    temp /= 10;
}

Result in temp

#!/bin/bash  
# functiontest.sh a sample to call the function in the shell script

function process_install

  commands...
}  

function process_exit  
{
  commands...  
}  

function main  
{  
  if [[ "$choice" == "true" ]]; then  
      process_install
  elif [[ "$choice" == "false" ]]; then  
      process_exit  
  fi  
}  

main "$@"  

it will start from the main function

HTML 5 allows summary tag, details element. That can be used to view or hide (collapse/expand) a section. Link

I have the same problem.

I have found this solution:

Google may block sign in attempts from some apps or devices that do not use modern security standards. Since these apps and devices are easier to break into, blocking them helps keep your account safer.

Some examples of apps that do not support the latest security standards include:

• The Mail app on your iPhone or iPad with iOS 6 or below
  
• The Mail app on your Windows phone preceding the 8.1 release
  
• Some Desktop mail clients like Microsoft Outlook and Mozilla Thunderbird

Therefore, you have to enable Less Secure Sign-In (or Less secure app access) in your google account.

After sign into google account, go to:

https://www.google.com/settings/security/lesssecureapps
or
https://myaccount.google.com/lesssecureapps

In C#, you can use the following code:

using (MailMessage mail = new MailMessage())
{
    mail.From = new MailAddress("[email protected]");
    mail.To.Add("[email protected]");
    mail.Subject = "Hello World";
    mail.Body = "<h1>Hello</h1>";
    mail.IsBodyHtml = true;
    mail.Attachments.Add(new Attachment("C:\\file.zip"));

    using (SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587))
    {
        smtp.Credentials = new NetworkCredential("[email protected]", "password");
        smtp.EnableSsl = true;
        smtp.Send(mail);
    }
}

This function has improved random distribution over the current function in @appas' answer as of Sept 9, 2017:

The @appas function is also incomplete, given there is no seed supplied (uv is not a seed - same for every frame), and does not work with low precision chipsets. Gold Noise runs at low precision by default (much faster).

In my case, I deleted the Previous Project & created a new project with different name, when i was building the Project it shows me the same error.

I just edited the Project Name in csproj file of the Project & it Worked...!

Use above annotation if someone is facing :--org.hibernate.jpa.HibernatePersistenceProvider persistence provider when it attempted to create the container entity manager factory for the paymentenginePU persistence unit. The following error occurred: [PersistenceUnit: paymentenginePU] Unable to build Hibernate SessionFactory ** This is a solution if you are using Audit table.@Audit

If you are using WiX look at this (there is a bug) http://www.cnblogs.com/xixifusigao/archive/2012/03/20/2407651.html

Sometimes new build configurations get added to the .wixproj file further down the file, that is, separated from their sibling config definitions by other unrelated XML elements.

Simply edit the .wixproj file so that all the <PropertyGroup> sections that define your build configs are adjacent to one another. (To edit the .wixproj in VS2013 right click on project in Solution Explorer, Unload project, right-click again->Edit YourProject.wixproj. Reload after editing the file.)

Try:

ArrayListname.get(index);

Where index is the position in the index and ArrayListname is the name of the Arraylist as in your case is mainList.

I can't believe no one has answered this yet! A rare occurrence on SO!

The question doesn't quite make sense to me. But I'll give it a stab. If you're asking about direct drawing to a canvas (polygons, shading, text etc...) vs. loading a bitmap and blitting it onto the canvas that would depend on the complexity of your drawing. As the drawing gets more complex the CPU time required will increase accordingly. However, blitting a bitmap onto a canvas will always be a constant time which is proportional to the size of the bitmap.

2

Without knowing what "something" is how can I show you how to do it? You should be able to figure out #2 from the answer for #3.

3

Assumptions:

• bmp1 is larger than bmp2.

• You want them both overlaid from the top left corner.

      private Bitmap overlay(Bitmap bmp1, Bitmap bmp2) {
          Bitmap bmOverlay = Bitmap.createBitmap(bmp1.getWidth(), bmp1.getHeight(), bmp1.getConfig());
          Canvas canvas = new Canvas(bmOverlay);
          canvas.drawBitmap(bmp1, new Matrix(), null);
          canvas.drawBitmap(bmp2, new Matrix(), null);
          return bmOverlay;
      }
  

Use two submit buttons.

<input id="sub" name="sub" type="submit" value="OK, Save">
<input id="sub2" name="sub2" type="submit" value="Hidden Submit" style="display:none">

And jQuery:

$("#sub").click(function(){
  $(this).val("Please wait..");
  $(this).attr("disabled","disabled");
  $("#sub2").click();
});

The jquery form plugin offers an easy way to iterate over your form elements and put them in a query string. It might also be useful for whatever else you need to do with these values.

var queryString = $('#myFormId').formSerialize();

From http://malsup.com/jquery/form

Or using straight jquery:

var queryString = $('#myFormId').serialize();

My case, the server was encrypting with padding disabled. But the client was trying to decrypt with the padding enabled.

While using EVP_CIPHER*, by default the padding is enabled. To disable explicitly we need to do

EVP_CIPHER_CTX_set_padding(context, 0);

So non matching padding options can be one reason.

I was trying to achieve the exact opposite when I bumped on this thread. I know it's quite old, but here's my solution nonetheless. You can use blocks, see here. In this case, compile the following code (with the right imports):

> String s = "äêìóblah"; 
> Pattern p = Pattern.compile("[\\p{InLatin-1Supplement}]+"); // this regex uses a block
> Matcher m = p.matcher(s);
> System.out.println(m.find());
> System.out.println(s.replaceAll(p.pattern(), "#"));

You should see the following output:

true

#blah

Best,

The default class constructor is called unless you explicitly call another constructor in the derived class. the language specifies this.

Rectangle(int h,int w):
   Shape(h,w)
  {...}

Will call the other base class constructor.

There's a static method in ToolStripRenderer class, named CreateDisabledImage. Its usage is as simple as:

Bitmap c = new Bitmap("filename");
Image d = ToolStripRenderer.CreateDisabledImage(c);

It uses a little bit different matrix than the one in the accepted answer and additionally multiplies it by a transparency of value 0.7, so the effect is slightly different than just grayscale, but if you want to just get your image grayed, it's the simplest and best solution.

Looks like we're coding the same application ;-)
Here is my current implementation. I'm still in the beta testing phase of my GPS uploader app, so there might be many possible improvements. but it seems to work pretty well so far.

/**

    Location gpslocation = getLocationByProvider(LocationManager.GPS_PROVIDER);
    Location networkLocation =

    // if we have only one location available, the choice is easy
    if (gpslocation == null) {
        Log.d(TAG, "No GPS Location available.");
        return networkLocation;
    }
    if (networkLocation == null) {
        Log.d(TAG, "No Network Location available");
        return gpslocation;
    }
    // a locationupdate is considered 'old' if its older than the configured
    // update interval. this means, we didn't get a
    // update from this provider since the last check
    long old = System.currentTimeMillis() - getGPSCheckMilliSecsFromPrefs();
    boolean gpsIsOld = (gpslocation.getTime() < old);
    boolean networkIsOld = (networkLocation.getTime() < old);
    // gps is current and available, gps is better than network
    if (!gpsIsOld) {
        Log.d(TAG, "Returning current GPS Location");
        return gpslocation;

    // gps is old, we can't trust it. use network location
    if (!networkIsOld) {
        Log.d(TAG, "GPS is old, Network is current, returning network");
        return networkLocation;
    }
    // both are old return the newer of those two
    if (gpslocation.getTime() > networkLocation.getTime()) {
        Log.d(TAG, "Both are old, returning gps(newer)");
        return gpslocation;
    } else {
        Log.d(TAG, "Both are old, returning network(newer)");
        return networkLocation;
    }
}

/**
 * get the last known location from a specific provider (network/gps)
 */
private Location getLocationByProvider(String provider) {
    Location location = null;
    if (!isProviderSupported(provider)) {
        return null;
    }
    LocationManager locationManager = (LocationManager) getApplicationContext()

        }
    } catch (IllegalArgumentException e) {
        Log.d(TAG, "Cannot acces Provider " + provider);
    }
    return location;
}

Edit: here is the part that requests the periodic updates from the location providers:

public void startRecording() {
    gpsTimer.cancel();
    gpsTimer = new Timer();
    long checkInterval = getGPSCheckMilliSecsFromPrefs();
    long minDistance = getMinDistanceFromPrefs();
    // receive updates
    LocationManager locationManager = (LocationManager) getApplicationContext()
            .getSystemService(Context.LOCATION_SERVICE);
    for (String s : locationManager.getAllProviders()) {
        locationManager.requestLocationUpdates(s, checkInterval,
                minDistance, new LocationListener() {

                    @Override
                    public void onStatusChanged(String provider,
                            int status, Bundle extras) {}

                    @Override
                    public void onProviderEnabled(String provider) {}

                    @Override
                    public void onProviderDisabled(String provider) {}

                    @Override
                    public void onLocationChanged(Location location) {
                        // if this is a gps location, we can use it
                        if (location.getProvider().equals(
                                LocationManager.GPS_PROVIDER)) {
                            doLocationUpdate(location, true);
                        }
                    }
                });
        // //Toast.makeText(this, "GPS Service STARTED",
        // Toast.LENGTH_LONG).show();
        gps_recorder_running = true;
    }
    // start the gps receiver thread
    gpsTimer.scheduleAtFixedRate(new TimerTask() {

        @Override
        public void run() {
            Location location = getBestLocation();
            doLocationUpdate(location, false);
        }
    }, 0, checkInterval);
}

public void doLocationUpdate(Location l, boolean force) {
    long minDistance = getMinDistanceFromPrefs();
    Log.d(TAG, "update received:" + l);
    if (l == null) {
        Log.d(TAG, "Empty location");
        if (force)
            Toast.makeText(this, "Current location not available",
                    Toast.LENGTH_SHORT).show();
        return;
    }
    if (lastLocation != null) {
        float distance = l.distanceTo(lastLocation);
        Log.d(TAG, "Distance to last: " + distance);
        if (l.distanceTo(lastLocation) < minDistance && !force) {
            Log.d(TAG, "Position didn't change");
            return;
        }
        if (l.getAccuracy() >= lastLocation.getAccuracy()
                && l.distanceTo(lastLocation) < l.getAccuracy() && !force) {
            Log.d(TAG,
                    "Accuracy got worse and we are still "
                      + "within the accuracy range.. Not updating");
            return;
        }
        if (l.getTime() <= lastprovidertimestamp && !force) {
            Log.d(TAG, "Timestamp not never than last");
            return;
        }
    }
    // upload/store your location here
}

Things to consider:

• do not request GPS updates too often, it drains battery power. I currently use 30 min as default for my application.

• add a 'minimum distance to last known location' check. without this, your points will "jump around" when GPS is not available and the location is being triangulated from the cell towers. or you can check if the new location is outside of the accuracy value from the last known location.

string = 'string%d' % (i,)

I found this CSS-only library to be very helpful: https://lokesh-coder.github.io/pretty-checkbox/

Or, you could roll your own with this same basic concept, similar to what @Sharcoux posted. It's basically:

• Hide the normal checkbox (opacity 0 and placed where it would go)
• Add a css-based fake checkbox
• Use input:checked~div label for the checked style
• make sure your <label> is clickable using for=yourinputID

Finally this is for Hibernate 5 in Tomcat.

Compiled all the answers from the above and added my tips which works like a charm for Hibernate 5 and SQL Server 2014.

<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">
   org.hibernate.dialect.SQLServerDialect
</property>
<property name="hibernate.connection.driver_class">
   com.microsoft.sqlserver.jdbc.SQLServerDriver
</property>
<property name="hibernate.connection.url">  
jdbc:sqlserver://localhost\ServerInstanceOrServerName:1433;databaseName=DATABASE_NAME 
</property>
<property name="hibernate.default_schema">theSchemaNameUsuallydbo</property>
<property name="hibernate.connection.username">
   YourUsername
</property>
<property name="hibernate.connection.password">
   YourPasswordForMSSQL
</property>

Just don't anchor your pattern:

/Test/

The above regex will check for the literal string "Test" being found somewhere within it.

As per official guidelines and from performance point of view they appear equivalent (ANisus answer), the s != "" would be better due to a syntactical advantage. s != "" will fail at compile time if the variable is not a string, while len(s) == 0 will pass for several other data types.

To convert a date retrieved from MySQL into the format requested (mm/dd/yy H:M (AM/PM)):

// $datetime is something like: 2014-01-31 13:05:59
$time = strtotime($datetimeFromMysql);
$myFormatForView = date("m/d/y g:i A", $time);
// $myFormatForView is something like: 01/31/14 1:05 PM

Refer to the PHP date formatting options to adjust the format.

model.predict() expects the first parameter to be a numpy array. You supply a list, which does not have the shape attribute a numpy array has.

Otherwise your code looks fine, except that you are doing nothing with the prediction. Make sure you store it in a variable, for example like this:

prediction = model.predict(np.array(tk.texts_to_sequences(text)))
print(prediction)

As of Spark 2.0.0, you can do the following.

Case Class

Let's define a Person case class:

scala> case class Person(id: Int, name: String)
defined class Person

Import spark SparkSession implicit Encoders:

scala> import spark.implicits._
import spark.implicits._

And use SparkSession to create an empty Dataset[Person]:

scala> spark.emptyDataset[Person]
res0: org.apache.spark.sql.Dataset[Person] = [id: int, name: string]

Schema DSL

You could also use a Schema "DSL" (see Support functions for DataFrames in org.apache.spark.sql.ColumnName).

scala> val id = $"id".int
id: org.apache.spark.sql.types.StructField = StructField(id,IntegerType,true)

scala> val name = $"name".string
name: org.apache.spark.sql.types.StructField = StructField(name,StringType,true)

scala> import org.apache.spark.sql.types.StructType
import org.apache.spark.sql.types.StructType

scala> val mySchema = StructType(id :: name :: Nil)
mySchema: org.apache.spark.sql.types.StructType = StructType(StructField(id,IntegerType,true), StructField(name,StringType,true))

scala> import org.apache.spark.sql.Row
import org.apache.spark.sql.Row

scala> val emptyDF = spark.createDataFrame(sc.emptyRDD[Row], mySchema)
emptyDF: org.apache.spark.sql.DataFrame = [id: int, name: string]

scala> emptyDF.printSchema
root
 |-- id: integer (nullable = true)
 |-- name: string (nullable = true)

Store your results in variables, and use them in your HTML and add the necessary styling.

$usercity = $ip['cityName'];
$usercountry = $ip['countryName'];

And in the HTML, you could do:

<div id="userdetails">
<p> User's IP: <?php echo $usercity; ?> </p>
<p> Country: <?php echo $usercountry; ?> </p>
</div>

Now, you can simply add the styles for country class in your CSS, like so:

#userdetails {

/* styles go here */

}

Alternatively, you could also use this in your HTML:

<p style="font-size:15px; font-color: green;"><?php echo $userip; ?> </p>
<p style="font-size:15px; font-color: green;"><?php echo $usercountry; ?> </p>

Hope this helps!

I know this is 8 years old, but no one seems to have actually read and answered the question.

You can call .values() on a dict to get a list of the inner dicts and thus access them by index.

>>> mydict = {
...  'Apple': {'American':'16', 'Mexican':10, 'Chinese':5},
...  'Grapes':{'Arabian':'25','Indian':'20'} }

>>>mylist = list(mydict.values())
>>>mylist[0]
{'American':'16', 'Mexican':10, 'Chinese':5},
>>>mylist[1]
{'Arabian':'25','Indian':'20'}

>>>myInnerList1 = list(mylist[0].values())
>>>myInnerList1
['16', 10, 5]
>>>myInnerList2 = list(mylist[1].values())
>>>myInnerList2
['25', '20']

Here's a Boolean thing:

if (not suffix == "flac" )  or (not suffix == "cue" ):   # WRONG! FAILS
    print  filename + ' is not a flac or cue file'

but

if not (suffix == "flac"  or suffix == "cue" ):     # CORRECT!
       print  filename + ' is not a flac or cue file'

(not a) or (not b) == not ( a and b ) , is false only if a and b are both true

not (a or b) is true only if a and be are both false.

How about wait-notify

private Boolean bool = true;
private final Object lock = new Object();

private Boolean getChange(){
  synchronized(lock){
    while (bool) {
      bool.wait();
    }
   }
  return bool;
}
public void setChange(){
   synchronized(lock){
       bool = false;
       bool.notify();
   }
}

You can use as well:

var x = "somestring";

console.log(x.split("")[0]); // output "s"

This should work with older browsers.

For ng-click working properly you need define your controller after angularjs script binding and use it via $scope.

Just an extra comment on something that is often overlooked. Sometimes not using a surrogate key has benefits in the child tables. Let's say we have a design that allows you to run multiple companies within the one database (maybe it's a hosted solution, or whatever).

Let's say we have these tables and columns:

Company:
  CompanyId   (primary key)

CostCenter:
  CompanyId   (primary key, foreign key to Company)
  CostCentre  (primary key)

CostElement
  CompanyId   (primary key, foreign key to Company)
  CostElement (primary key)

Invoice:
  InvoiceId    (primary key)
  CompanyId    (primary key, in foreign key to CostCentre, in foreign key to CostElement)
  CostCentre   (in foreign key to CostCentre)
  CostElement  (in foreign key to CostElement)

In case that last bit doesn't make sense, Invoice.CompanyId is part of two foreign keys, one to the CostCentre table and one to the CostElement table. The primary key is (InvoiceId, CompanyId).

In this model, it's not possible to screw-up and reference a CostElement from one company and a CostCentre from another company. If a surrogate key was used on the CostElement and CostCentre tables, it would be.

The fewer chances to screw up, the better.

My situation was that I did not have a main function.

You should be able to solve this problem with one cte view and one batch file containing the bcp code. First create the view. Since, it's relatively straightforward, I did not create a temporary table. Normally I do

CREATE VIEW [dbo].[vwxMySAMPLE_EXTRACT_COLUMNS]
  AS
    WITH MYBCP_CTE (COLUMN_NM, ORD_POS, TXT)
     AS
      ( SELECT  COLUMN_NAME
             , ORDINAL_POSITION
             , CAST(COLUMN_NAME AS VARCHAR(MAX))
        FROM [INFORMATION_SCHEMA].[COLUMNS]
        WHERE TABLE_NAME = 'xMySAMPLE_EXTRACT_NEW'
        AND ORDINAL_POSITION = 1

        UNION ALL

        SELECT  V.COLUMN_NAME
              , V.ORDINAL_POSITION
              , CAST(C.TXT + '|' + V.COLUMN_NAME AS VARCHAR(MAX))
        FROM [INFORMATION_SCHEMA].[COLUMNS]  V INNER JOIN MYBCP_CTE C
        ON V.ORDINAL_POSITION = C.ORD_POS+1
        AND V.ORDINAL_POSITION > 1
        WHERE TABLE_NAME = 'xMySAMPLE_EXTRACT_NEW'
      )

      SELECT CC.TXT
      FROM MYBCP_CTE CC INNER JOIN ( SELECT MAX(ORD_POS) AS MX_CNT
                                     FROM MYBCP_CTE C
                                    ) SC
      ON CC.ORD_POS = SC.MX_CNT

Now, create the batch file. I created this in my Temp directory, but I'm lazy.

  cd\
  CD "C:\Program Files\Microsoft SQL Server\110\Tools\Binn"

  set buildhour=%time: =0%
  set buildDate=%DATE:~4,10%
  set backupfiledate=%buildDate:~6,4%%buildDate:~0,2%%buildDate:~3,2%%time:~0,2%%time:~3,2%%time:~6,2%

  echo %backupfiledate%
  pause

The above code just creates a date to append to the end of your file... Next, the first bcp statement with the view to the recursive cte to concatenate it all together.

  bcp "SELECT *  FROM [dbo].[vwxMYSAMPLE_EXTRACT_COLUMNS] OPTION (MAXRECURSION 300)" queryout C:\Temp\Col_NM%backupfiledate%.txt -c -t"|" -S MYSERVERTOLOGINTO -T -q
  bcp "SELECT *  FROM [myDBName].[dbo].[vwxMYSAMPLE_EXTRACT_NEW] " queryout C:\Temp\3316_PHYSDATA_ALL%backupfiledate%.txt -c -t"|" -S MYSERVERTOLOGINTO -T -q

Now merge them together using the copy command:

  copy C:\Temp\Col_NM%backupfiledate%.txt  + C:\Temp\3316_PHYSDATA_ALL%backupfiledate%.txt  C:\Temp\3316_PHYSDATA_ALL%backupfiledate%.csv

All set

If you are looking for 1st Number with decimal as string has correct decimal places, you may try regexp_substr function like this:

regexp_substr('stack12.345overflow', '\.*[[:digit:]]+\.*[[:digit:]]*')

It is undefined behaviour to attempt to modify string literals, which is what something like:

strcat ("Hello, ", name);

will attempt to do. It will try to tack on the name string to the end of the string literal "Hello, ", which is not well defined.

Try something this. It achieves what you appear to be trying to do:

char message[1000];
strcpy (message, "TEXT ");
strcat (message, var);

This creates a buffer area that is allowed to be modified and then copies both the string literal and other text to it. Just be careful with buffer overflows. If you control the input data (or check it before-hand), it's fine to use fixed length buffers like I have.

Otherwise, you should use mitigation strategies such as allocating enough memory from the heap to ensure you can handle it. In other words, something like:

const static char TEXT[] = "TEXT ";

// Make *sure* you have enough space.

char *message = malloc (sizeof(TEXT) + strlen(var) + 1);
if (message == NULL)
     handleOutOfMemoryIntelligently();
strcpy (message, TEXT);
strcat (message, var);

// Need to free message at some point after you're done with it.

I think that some of the confusion comes from the difference between the concept of a tag and the implementation in SVN. To SVN a tag is a branch which is a copy. Modifying tags is considered wrong and in fact tools like TortoiseSVN will warn you if you attempt to modify anything with ../tags/.. in the path.

I think it should be like this..

<?php
require_once ( 'username.php' );

echo '
<form name="form1" method="post" action="<?php username() ?>">
 <p>
  <label>
   <input type="text" name="textfield" id="textfield">
  </label>
 </p>
 <p>
  <label>
   <input type="submit" name="button" id="button" value="Submit">
  </label>
 </p>
</form>';
?>

Add a reference to System.Windows.Form.DataVisualization, then add the appropriate using statement:

using System.Windows.Forms.DataVisualization.Charting;

private void CreateChart()
{
    var series = new Series("Finance");

    // Frist parameter is X-Axis and Second is Collection of Y- Axis
    series.Points.DataBindXY(new[] { 2001, 2002, 2003, 2004 }, new[] { 100, 200, 90, 150 });
    chart1.Series.Add(series);

}

Use str_pad function. It is very easy to use. One example is below:

<?php

$input = "Alien";
echo str_pad($input, 10);                      // produces "Alien     "

?>

You Can Wrap your widget with Flexible Widget and than you can set property of Text using overflow property of Text Widget. you have to set TextOverflow.clip for example:-

Flexible
(child: new Text("This is Dummy Long Text",
 style: TextStyle(
 fontFamily: "Roboto",
 color: Colors.black,
 fontSize: 10.0,
 fontWeight: FontWeight.bold),
 overflow: TextOverflow.clip,),)

hope this help someone :)

From java.util.Date to XMLGregorianCalendar you can simply do:

import javax.xml.datatype.XMLGregorianCalendar;
import javax.xml.datatype.DatatypeFactory;
import java.util.GregorianCalendar;
......
GregorianCalendar gcalendar = new GregorianCalendar();
gcalendar.setTime(yourDate);
XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance().newXMLGregorianCalendar(gcalendar);

Code edited after the first comment of @f-puras, by cause i do a mistake.

MM/DD/YYYY format

If you have the MM/DD/YYYY format which is default for JavaScript, you can simply pass your string to Date(string) constructor. It will parse it for you.

var dateString = "10/23/2015"; // Oct 23_x000D_
_x000D_
var dateObject = new Date(dateString);_x000D_
_x000D_
document.body.innerHTML = dateObject.toString();

DD/MM/YYYY format - manually

If you work with this format, then you can split the date in order to get day, month and year separately and then use it in another constructor - Date(year, month, day):

var dateString = "23/10/2015"; // Oct 23_x000D_
_x000D_
var dateParts = dateString.split("/");_x000D_
_x000D_
// month is 0-based, that's why we need dataParts[1] - 1_x000D_
var dateObject = new Date(+dateParts[2], dateParts[1] - 1, +dateParts[0]); _x000D_
_x000D_
document.body.innerHTML = dateObject.toString();

For more information, you can read article about Date at Mozilla Developer Network.

DD/MM/YYYY - using moment.js library

Alternatively, you can use moment.js library, which is probably the most popular library to parse and operate with date and time in JavaScript:

var dateString = "23/10/2015"; // Oct 23_x000D_
_x000D_
var dateMomentObject = moment(dateString, "DD/MM/YYYY"); // 1st argument - string, 2nd argument - format_x000D_
var dateObject = dateMomentObject.toDate(); // convert moment.js object to Date object_x000D_
_x000D_
document.body.innerHTML = dateObject.toString();

<script src="https://momentjs.com/downloads/moment.min.js"></script>

In all three examples dateObject variable contains an object of type Date, which represents a moment in time and can be further converted to any string format.

Open a terminal window. Type:

node -v

This will display your nodejs version.

Navigate to where you saved your script and input:

node script.js

This will run your script.

Alternatively you can install GNU date like so:

1. install Homebrew: https://brew.sh/
2. brew install coreutils
3. add to your bash_profile: alias date="/usr/local/bin/gdate"
4. date +%s 1547838127

Comments saying Mac has to be "different" simply reveal the commenter is ignorant of the history of UNIX. macOS is based on BSD UNIX, which is way older than Linux. Linux essentially was a copy of other UNIX systems, and Linux decided to be "different" by adopting GNU tools instead of BSD tools. GNU tools are more user friendly, but they're not usually found on any *BSD system (just the way it is).

Really, if you spend most of your time in Linux, but have a Mac desktop, you probably want to make the Mac work like Linux. There's no sense in trying to remember two different sets of options, or scripting for the mac's BSD version of Bash, unless you are writing a utility that you want to run on both BSD and GNU/Linux shells.

make sure you don't have env variable NODE_ENV set to 'production'.

If you do, dev dependencies will not be installed without the --dev flag

Your string is invalid, but assuming it was valid, you'd have to do:

var finalData = str.replace(/\\/g, "");

When you want to replace all the occurences with .replace, the first parameter must be a regex, if you supply a string, only the first occurrence will be replaced, that's why your replace wouldn't work.

Cheers

Just include the standard library in your code.

#include<algorithm>

Array size will be denoted as n

Your old Array

int oldArray[n]={10,20,30,40,50};

Declare New Array in which you have to copy your old array value

int newArray[n];

Use this

copy_n(oldArray,n,newArray);

I accomplished something similar using jQuery Waypoints.

There's a lot of moving parts, and quite a bit of logic (that I hope to get on GitHub some day soon), but essentially what you could do is...

1. Duplicate the table DOM structure in JavaScript and add a class called fixed.
2. Add styles for table.fixed that make it invisible.
3. Set a way point at the bottom of the header navigation that adds a class called sticky to table.fixed
4. Add styles for table.sticky.fixed that position it just below the navbar and also make just the thead content visible. This also has a z-index so it is laid above the rest of the content.
5. Add another waypoint, but in the downward scroll event, that removes .sticky from the table.fixed

You have to duplicate the entire table DOM in order to ensure column widths line up appropriately.

If that sounds really complicated, you might want to try playing around with the DataTables plugin and the FixedHeader extension: https://datatables.net/extensions/fixedheader/

function timeStr(d) { 
  return ''+
    d.getFullYear()+
    ('0'+(d.getMonth()+1)).slice(-2)+
    ('0'+d.getDate()).slice(-2)+
    ('0'+d.getHours()).slice(-2)+
    ('0'+d.getMinutes()).slice(-2)+
    ('0'+d.getSeconds()).slice(-2);
}

As suggested by Mark Ransom, I found the right encoding for that problem. The encoding was "ISO-8859-1", so replacing open("u.item", encoding="utf-8") with open('u.item', encoding = "ISO-8859-1") will solve the problem.

For Current date and time as the name for a file on the file system. Now call the string.Format method, and combine it with DateTime.Now, for a method that outputs the correct string based on the date and time.

using System;
using System.IO;

class Program
{
    static void Main()
    {
        //
        // Write file containing the date with BIN extension
        //
        string n = string.Format("text-{0:yyyy-MM-dd_hh-mm-ss-tt}.bin",
            DateTime.Now);
        File.WriteAllText(n, "abc");
    }
}

Output :

C:\Users\Fez\Documents\text-2020-01-08_05-23-13-PM.bin

"text-{0:yyyy-MM-dd_hh-mm-ss-tt}.bin"

text- The first part of the output required Files will all start with text-

{0: Indicates that this is a string placeholder The zero indicates the index of the parameters inserted here

yyyy- Prints the year in four digits followed by a dash This has a "year 10000" problem

MM- Prints the month in two digits

dd_ Prints the day in two digits followed by an underscore

hh- Prints the hour in two digits

mm- Prints the minute, also in two digits

ss- As expected, it prints the seconds

tt Prints AM or PM depending on the time of day

I think it's quite dangerous to rely on the order of the values in a enum and to assume that the first is always the default. This would be good practice if you are concerned about protecting the default value.

enum E
{
    Foo = 0, Bar, Baz, Quux
}

Otherwise, all it takes is a careless refactor of the order and you've got a completely different default.

Its an XML namespace. It is required when you use XHTML 1.0 or 1.1 doctypes or application/xhtml+xml mimetypes.

You should be using HTML5 doctype, then you don't need it for text/html. Better start from template like this :

<!DOCTYPE html>
<html>
    <head>
        <meta charset=utf-8 />
        <title>domcument title</title>
        <link rel="stylesheet" href="/stylesheet.css" type="text/css" />
    </head>
    <body>
            <!-- your html content -->
            <script src="/script.js"></script>
    </body>
</html>

When you have put your Doctype straight - do and validate you html and your css .
That usually will sove you layout issues.

According to the official ReactJs documentation, you need to pass argument in the default format witch is:

P = {} // default for your props
S = {} // default for yout state

interface Component<P = {}, S = {}> extends ComponentLifecycle<P, S> { }

Or to define your own type like below: (just an exp)

interface IProps {
    clients: Readonly<IClientModel[]>;

    onSubmit: (data: IClientModel) => void;
}

interface IState {
   clients: Readonly<IClientModel[]>;
   loading: boolean;
}

class ClientsPage extends React.Component<IProps, IState> {
  // ...
}

If you have a class for each of your input box, then you can do it as

        var checked = []
        $('input.Booking').each(function ()
        {
            checked.push($(this).val());
        });

just this:

str = Replace(str, vbCrLf, "")

def flatten_nested_dict(_dict, _str=''):
    '''
    recursive function to flatten a nested dictionary json
    '''
    ret_dict = {}
    for k, v in _dict.items():
        if isinstance(v, dict):
            ret_dict.update(flatten_nested_dict(v, _str = '_'.join([_str, k]).strip('_')))
        elif isinstance(v, list):
            for index, item in enumerate(v):
                if isinstance(item, dict):
                    ret_dict.update(flatten_nested_dict(item,  _str= '_'.join([_str, k, str(index)]).strip('_')))
                else:
                    ret_dict['_'.join([_str, k, str(index)]).strip('_')] = item
        else:
            ret_dict['_'.join([_str, k]).strip('_')] = v
    return ret_dict

Check this

 SELECT A.OtherID,  
     Split.a.value('.', 'VARCHAR(100)') AS Data  
 FROM  
 (
     SELECT OtherID,  
         CAST ('<M>' + REPLACE(Data, ',', '</M><M>') + '</M>' AS XML) AS Data  
     FROM  Table1
 ) AS A CROSS APPLY Data.nodes ('/M') AS Split(a);

A user above says "well, you'll never really need to go above 10 for most designs."

Depending on your project, you may only need z-indexes 0-1, or z-indexes 0-10000. You'll often need to play in the higher digits...especially if you are working with lightbox viewers (9999 seems to be the standard and if you want to top their z-index, you'll need to exceed that!)

• The children of a row-flexbox container automatically fill the container's vertical space.

• Specify flex: 1; for a child if you want it to fill the remaining horizontal space:

To reorder the rows of a DataFrame just use a list as follows.

df = df[['Mid', 'Net', 'Upper', 'Lower', 'Zsore']]

This makes it very obvious what was done when reading the code later. Also use:

df.columns
Out[1]: Index(['Net', 'Upper', 'Lower', 'Mid', 'Zsore'], dtype='object')

Then cut and paste to reorder.

For a DataFrame with many columns, store the list of columns in a variable and pop the desired column to the front of the list. Here is an example:

cols = [str(col_name) for col_name in range(1001)]
data = np.random.rand(10,1001)
df = pd.DataFrame(data=data, columns=cols)

mv_col = cols.pop(cols.index('77'))
df = df[[mv_col] + cols]

Now df.columns has.

Index(['77', '0', '1', '2', '3', '4', '5', '6', '7', '8',
       ...
       '991', '992', '993', '994', '995', '996', '997', '998', '999', '1000'],
      dtype='object', length=1001)

You can use either sbt or maven to compile spark programs. Simply add the spark as dependency to maven

<repository>
      <id>Spark repository</id>
      <url>http://www.sparkjava.com/nexus/content/repositories/spark/</url>
</repository>

And then the dependency:

<dependency>
      <groupId>spark</groupId>
      <artifactId>spark</artifactId>
      <version>1.2.0</version>
</dependency>

In terms of running a file with spark commands: you can simply do this:

echo"
   import org.apache.spark.sql.*
   ssc = new SQLContext(sc)
   ssc.sql("select * from mytable").collect
" > spark.input

Now run the commands script:

cat spark.input | spark-shell

You can manipulate the stylesheets and stylesheet rules themselves with javascript

var sheetCount = document.styleSheets.length;
var lastSheet = document.styleSheets[sheetCount-1];
var ruleCount;
if (lastSheet.cssRules) { // Firefox uses 'cssRules'
    ruleCount = lastSheet.cssRules.length;
}
else if (lastSheet.rules) { / /IE uses 'rules'
    ruleCount = lastSheet.rules.length;
}
var newRule = "a:hover { text-decoration: none !important; color: #000 !important; }";
// insert as the last rule in the last sheet so it
// overrides (not overwrites) previous definitions
lastSheet.insertRule(newRule, ruleCount);

Making the attributes !important and making this the very last CSS definition should override any previous definition, unless one is more specifically targeted. You may have to insert more rules in that case.

Be careful here.

FlushDB deletes all keys in the current database while FlushALL deletes all keys in all databases on the current host.

/usr/local/ssl/openssl.cnf

is soft link of

/etc/ssl/openssl.cnf

You can see that using long list (ls -l) on the /usr/local/ssl/ directory where you will find

To expand on John's answer you can also use the Dockerfile CMD command as following (in case you want it to self start without additional args)

CMD ["nginx", "-g", "daemon off;"]

Try this,

1. If you want to skip a particular iteration, use continue.

2. If you want to break out of the immediate loop use break

3 If there are 2 loop, outer and inner.... and you want to break out of both the loop from the inner loop, use break with label.

eg:

continue

for(int i=0 ; i<5 ; i++){

    if (i==2){

      continue;
    }
 }

eg:

break

for(int i=0 ; i<5 ; i++){

        if (i==2){

          break;
        }
     }

eg:

break with label

lab1: for(int j=0 ; j<5 ; j++){
     for(int i=0 ; i<5 ; i++){

        if (i==2){

          break lab1;
        }
     }
  }

Look inside the implementation of the two methods to understand them deeply:

array1.equals(array2);

/**
 * Indicates whether some other object is "equal to" this one.
 * <p>
 * The {@code equals} method implements an equivalence relation
 * on non-null object references:
 * <ul>
 * <li>It is <i>reflexive</i>: for any non-null reference value
 *     {@code x}, {@code x.equals(x)} should return
 *     {@code true}.
 * <li>It is <i>symmetric</i>: for any non-null reference values
 *     {@code x} and {@code y}, {@code x.equals(y)}
 *     should return {@code true} if and only if
 *     {@code y.equals(x)} returns {@code true}.
 * <li>It is <i>transitive</i>: for any non-null reference values
 *     {@code x}, {@code y}, and {@code z}, if
 *     {@code x.equals(y)} returns {@code true} and
 *     {@code y.equals(z)} returns {@code true}, then
 *     {@code x.equals(z)} should return {@code true}.
 * <li>It is <i>consistent</i>: for any non-null reference values
 *     {@code x} and {@code y}, multiple invocations of
 *     {@code x.equals(y)} consistently return {@code true}
 *     or consistently return {@code false}, provided no
 *     information used in {@code equals} comparisons on the
 *     objects is modified.
 * <li>For any non-null reference value {@code x},

I also faced this error when I was adding firebase push notifications in my app. but in my case I was doing a very silly mistake which i noticed after some time. I declared below code in manifest two times. After removing duplicate declaration. my issue solved.

        <service   android:name="com.evampsaanga.mytelenor.firebase.MyFirebaseInstanceIDService">
        <intent-filter>
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
        </intent-filter>
    </service>`

so you also check if there is anything duplicate in your app manifest file.

You need to define a copy constructor, assignment, operator.

class Test {
   Test(const Test &that); //Copy constructor
   Test& operator= (const Test &rhs); //assignment operator
}

Your copy that is pushed on the queue is pointing to the same memory your original is. When the first is destructed, it deletes the memory. The second destructs and tries to delete the same memory.

Remove this from #info:

    margin-left:auto;

Add this for your header:

#info p {
    text-align: center;
}

Do you need the fixed width etc.? I removed the in my opinion not necessary stuff and centered the header with text-align.

you need to install and import reduce from functools python package

I have a similar problem, but I need to iterate monthly instead of daily.

This is my solution

import calendar
from datetime import datetime, timedelta

def days_in_month(dt):
    return calendar.monthrange(dt.year, dt.month)[1]

def monthly_range(dt_start, dt_end):
    forward = dt_end >= dt_start
    finish = False
    dt = dt_start

    while not finish:
        yield dt.date()
        if forward:
            days = days_in_month(dt)
            dt = dt + timedelta(days=days)            
            finish = dt > dt_end
        else:
            _tmp_dt = dt.replace(day=1) - timedelta(days=1)
            dt = (_tmp_dt.replace(day=dt.day))
            finish = dt < dt_end

Example #1

date_start = datetime(2016, 6, 1)
date_end = datetime(2017, 1, 1)

for p in monthly_range(date_start, date_end):
    print(p)

Output

2016-06-01
2016-07-01
2016-08-01
2016-09-01
2016-10-01
2016-11-01
2016-12-01
2017-01-01

Example #2

date_start = datetime(2017, 1, 1)
date_end = datetime(2016, 6, 1)

for p in monthly_range(date_start, date_end):
    print(p)

Output

There are many answers but Will some more observation it.

1. clip

Clip the overflowing text to fix its container.

SizedBox(
          width: 120.0,

@Max: is right about the creation time.

However, if you want to calculate the elapsed days argument for one of the -atime, -ctime, -mtime parameters, you can use the following expression

ELAPSED_DAYS=$(( ( $(date +%s) - $(date -d '2008-09-24' +%s) ) / 60 / 60 / 24 - 1 ))

Replace "2008-09-24" with whatever date you want and ELAPSED_DAYS will be set to the number of days between then and today. (Update: subtract one from the result to align with find's date rounding.)

So, to find any file modified on September 24th, 2008, the command would be:

find . -type f -mtime $(( ( $(date +%s) - $(date -d '2008-09-24' +%s) ) / 60 / 60 / 24 - 1 ))

This will work if your version of find doesn't support the -newerXY predicates mentioned in @Arve:'s answer.

You can use .shape

In: a = np.array([[1,2,3],[4,5,6]])
In: a.shape
Out: (2, 3)
In: a.shape[0] # x axis
Out: 2
In: a.shape[1] # y axis
Out: 3

For me the bold work when I change the font style from font-family: 'Open Sans', sans-serif; to Arial

The type int is a primitive and it cannot be null, if you want to return null, mark the signature as

public Integer pollDecrementHigherKey(int x) {
    x = 10;

    if (condition) {
        return x; // This is auto-boxing, x will be automatically converted to Integer
    } else if (condition2) {
        return null; // Integer inherits from Object, so it's valid to return null
    } else {
        return new Integer(x); // Create an Integer from the int and then return
    }
    
    return 5; // Also will be autoboxed and converted into Integer
}

"bigEnough" array is a bit of a stretch. Sure, buffer needs to be "big ebough" but proper design of an application should include transactions and delimiters. In this configuration each transaction would have a preset length thus your array would anticipate certain number of bytes and insert it into correctly sized buffer. Delimiters would ensure transaction integrity and would be supplied within each transaction. To make your application even better, you could use 2 channels (2 sockets). One would communicate fixed length control message transactions that would include information about size and sequence number of data transaction to be transferred using data channel. Receiver would acknowledge buffer creation and only then data would be sent. If you have no control over stream sender than you need multidimensional array as a buffer. Component arrays would be small enough to be manageable and big enough to be practical based on your estimate of expected data. Process logic would seek known start delimiters and then ending delimiter in subsequent element arrays. Once ending delimiter is found, new buffer would be created to store relevant data between delimiters and initial buffer would have to be restructured to allow data disposal.

As far as a code to convert stream into byte array is one below.

Stream s = yourStream;
int streamEnd = Convert.ToInt32(s.Length);
byte[] buffer = new byte[streamEnd];
s.Read(buffer, 0, streamEnd);

You have at least these 3 issues:

1. you are not getting the element's value properly
2. The div that you are trying to use to display whether the values have been saved or not has id display yet in your javascript you attempt to get element myDiv which is not even defined in your markup.
3. Never name variables with reserved keywords in javascript. using "string" as a variable name is NOT a good thing to do on most of the languages I can think of. I renamed your string variable to "content" instead. See below.

You can save all three values at once by doing:

var title=new Array();
var names=new Array();//renamed to names -added an S- 
                      //to avoid conflicts with the input named "name"
var tickets=new Array();

function insert(){
    var titleValue = document.getElementById('title').value;
    var actorValue = document.getElementById('name').value;
    var ticketsValue = document.getElementById('tickets').value;
    title[title.length]=titleValue;
    names[names.length]=actorValue;
    tickets[tickets.length]=ticketsValue;
  }

And then change the show function to:

function show() {
  var content="<b>All Elements of the Arrays :</b><br>";
  for(var i = 0; i < title.length; i++) {
     content +=title[i]+"<br>";
  }
  for(var i = 0; i < names.length; i++) {
     content +=names[i]+"<br>";
  }
  for(var i = 0; i < tickets.length; i++) {
     content +=tickets[i]+"<br>";
  }
  document.getElementById('display').innerHTML = content; //note that I changed 
                                                    //to 'display' because that's
                                              //what you have in your markup
}

Here's a jsfiddle for you to play around.

$prevmonth = date('M Y', strtotime("last month"));

$(this).value is attempting to call the 'value' property of a jQuery object, which does not exist. Native JavaScript does have a 'value' property on certain HTML objects, but if you are operating on a jQuery object you must access the value by calling $(this).val().

I have installed python2.7 and python3.6

Open Command Line to ~/.bash_profile I find that #Setting PATH for Python 3.6 , So I change the path to PATH="/usr/local/Cellar/python/2.7.13/bin:${PATH}" , (please make sure your python2.7's path) ,then save. It works for me.

To define "soft real-time," it is easiest to compare it with "hard real-time." Below we will see that the term "firm real-time" constitutes a misunderstanding about "soft real-time."

Speaking casually, most people implicitly have an informal mental model that considers information or an event as being "real-time"

• if, or to the extent that, it is manifest to them with a delay (latency) that can be related to its perceived currency

• i.e., in a time frame that the information or event has acceptably satisfactory value to them.

There are numerous different ad hoc definitions of "hard real-time," but in that mental model, hard real-time is represented by the "if" term. Specifically, assuming that real-time actions (such as tasks) have completion deadlines, acceptably satisfactory value of the event that all tasks complete is limited to the special case that all tasks meet their deadlines.

Hard real-time systems make the very strong assumptions that everything about the application and system and environment is static and known a' priori—e.g., which tasks, that they are periodic, their arrival times, their periods, their deadlines, that they won’t have resource conflicts, and overall the time evolution of the system. In an aircraft flight control system or automotive braking system and many other cases those assumptions can usually be satisfied so that all the deadlines will be met.

This mental model is deliberately and very usefully general enough to encompass both hard and soft real-time--soft is accommodated by the "to the extent that" phrase. For example, suppose that the task completions event has suboptimal but acceptable value if

• no more than 10% of the tasks miss their deadlines
• or no task is more than 20% tardy
• or the average tardiness of all tasks is no more than 15%
• or the maximum tardiness among all tasks is less than 10%

These are all common examples of soft real-time cases in a great many applications.

Consider the single-task application of picking your child up after school. That probably does not have an actual deadline, instead there is some value to you and your child based on when that event takes place. Too early wastes resources (such as your time) and too late has some negative value because your child might be left alone and potentially in harm's way (or at least inconvenienced).

Unlike the static hard real-time special case, soft real-time makes only the minimum necessary application-specific assumptions about the tasks and system, and uncertainties are expected. To pick up your child, you have to drive to the school, and the time to do that is dynamic depending on weather, traffic conditions, etc. You might be tempted to over-provision your system (i.e., allow what you hope is the worst case driving time) but again this is wasting resources (your time, and occupying the family vehicle, possibly denying use by other family members).

That example may not seem to be costly in terms of wasted resources, but consider other examples. All military combat systems are soft real-time. For example, consider performing an aircraft attack on a hostile ground vehicle using a missile guided with updates to it as the target maneuvers. The maximum satisfaction for completing the course update tasks is achieved by a direct destructive strike on the target. But an attempt to over-provision resources to make certain of this outcome is usually far too expensive and may even be impossible. In this case, you may be less but sufficiently satisfied if the missile strikes close enough to the target to disable it.

Obviously combat scenarios have a great many possible dynamic uncertainties that must be accommodated by the resource management. Soft real-time systems are also very common in many civilian systems, such as industrial automation, although obviously military ones are the most dangerous and urgent ones to achieve acceptably satisfactory value in.

The keystone of real-time systems is "predictability." The hard real-time case is interested in only one special case of predictability--i.e., that the tasks will all meet their deadlines and the maximum possible value will be achieved by that event. That special case is named "deterministic."

There is a spectrum of predictability. Deterministic (determinism) is one end-point (maximum predictability) on the predictability spectrum; the other end-point is minimum predictability (maximum non-determinism). The spectrum's metric and end-points have to be interpreted in terms of a chosen predictability model; everything between those two end-points is degrees of unpredictability (= degrees of non-determinism).

Most real-time systems (namely, soft ones) have non-deterministic predictability, for example, of the tasks' completions times and hence the values gained from those events.

In general (in theory), predictability, and hence acceptably satisfactory value, can be made as close to the deterministic end-point as necessary--but at a price which may be physically impossible or excessively expensive (as in combat or perhaps even in picking up your child from school).

Soft real-time requires an application-specific choice of a probability model (not the common frequentist model) and hence predictability model for reasoning about event latencies and resulting values.

Referring back to the above list of events that provide acceptable value, now we can add non-deterministic cases, such as

• the probability that no task will miss its deadline by more than 5% is greater than 0.87. (Note the number of scheduling criteria expressed in there.)

In a missile defense application, given the fact that in combat the offense always has the advantage over the defense, which of these two real-time computing scenarios would you prefer:

• because the perfect destruction of all the hostile missiles is very unlikely or impossible, assign your defensive resources to maximize the probability that as many of the most threatening (e.g., based on their targets) hostile missiles will be successfully intercepted (close interception counts because it can move the hostile missile off-course);

• complain that this is not a real-time computing problem because it is dynamic instead of static, and traditional real-time concepts and techniques do not apply, and it sounds more difficult than static hard real-time, so you are not interested in it.

Despite the various misunderstandings about soft real-time in the real-time computing community, soft real-time is very general and powerful, albeit potentially complex compared with hard real-time. Soft real-time systems as summarized here have a lengthy successful history of use outside the real-time computing community.

To directly answer the OP question:

A hard real-time system can provide deterministic guarantees—most commonly that all tasks will meet their deadlines, interrupt or system call response time will always be less than x, etc.—IF AND ONLY IF very strong assumptions are made and are correct that everything that matters is static and known a' priori (in general, such guarantees for hard real-time systems are an open research problem except for rather simple cases)

A soft real-time system does not make deterministic guarantees, it is intended to provide the best possible analytically specified and accomplished probabilistic timeliness and predictability of timeliness that are feasible under the current dynamic circumstances, according to application-specific criteria.

Obviously hard real-time is a simple special case of soft real-time. Obviously soft real-time's analytical non-deterministic assurances can be very complex to provide, but are mandatory in the most common real-time cases (including the most dangerous safety-critical ones such as combat) since most real-time cases are dynamic not static.

"Firm real-time" is an ill-defined special case of "soft real-time." There is no need for this term if the term "soft real-time" is understood and used properly.

I have a more detailed much more precise discussion of real-time, hard real-time, soft real-time, predictability, determinism, and related topics on my web site real-time.org.

You can override symbols in the stock libraries by creating a library with the same symbols and specifying the library in LD_PRELOAD.

Some people use it to specify libraries in nonstandard locations, but LD_LIBRARY_PATH is better for that purpose.

Use command

google-chrome-stable

We can also use command

google-chrome

To open terminal but in my case when I make an interrupt ctrl + c then it get closed so I would recommend to use google-chrome-stable instead of google-chrome

File FileOne.js:

module.exports = { ClientIDUnsplash : 'SuperSecretKey' };

File FileTwo.js:

var { ClientIDUnsplash } = require('./FileOne');

This example works best for React.

You can do the following :-

$(document).ready(function(){
    $("#id").trigger("click");
});

That's not possible using the built-in Array.prototype.map. However, you could use a simple for-loop instead, if you do not intend to map any values:

var hasValueLessThanTen = false;
for (var i = 0; i < myArray.length; i++) {
  if (myArray[i] < 10) {
    hasValueLessThanTen = true;
    break;
  }
}

Or, as suggested by @RobW, use Array.prototype.some to test if there exists at least one element that is less than 10. It will stop looping when some element that matches your function is found:

var hasValueLessThanTen = myArray.some(function (val) { 
  return val < 10;
});

Just as others stated you need to remove the ';' from:
;extension=php_mysql.dll and
;extension=php_mysqli.dll

in your php.ini to enable mysql and mysqli extensions. But MOST IMPORTANT of all, you should set the extension_dir in your php.ini to point to your extensions directory. The default most of the time is "ext". You should change it to the absolute path to the extensions folder. i.e. if you have your xampp installed on drive C, then C:/xampp/php/ext is the absolute path to the ext folder, and It should work like a charm!

If you want your result concatenated, as you show in your question, you could try something like:

>>> reduce(lambda x, y: str(x)+str(y), map(ord,"hello world"))
'10410110810811132119111114108100'

If you look at the first lines of text you can glean what your error is.

this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them

You're dynamically editing the lstProblems dropdown, so when you post back ASP.NET says "Warning! Invalid entries in the dropdown!" and freaks out throwing that error. You have to determine if turning off event validation is an OK solution, but I would research it before doing it, since the idea behind it is to make your site more secure for free.

Here's another stackoverflow answer that does a much better job explaining what to do than me: Invalid postback or callback argument. Event validation is enabled using '<pages enableEventValidation="true"/>'

You can use geom_col() directly. See the differences between geom_bar() and geom_col() in this link https://ggplot2.tidyverse.org/reference/geom_bar.html

geom_bar() makes the height of the bar proportional to the number of cases in each group If you want the heights of the bars to represent values in the data, use geom_col() instead.

ggplot(data_country)+aes(x=country,y = conversion_rate)+geom_col()

Just one command did the work

netsh http add iplisten 127.0.0.1

To display images and videos try this:

    Intent intent = new Intent();
    intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(intent, 1);
    startActivityForResult(Intent.createChooser(intent,"Wybierz plik"), SELECT_FILE);

I had the same issue, then I fix it by change configuration manager x86 -> x64 and build

You can join to the same table on the fields that would be duplicated and then anti-join on the id field. Select the id field from the first table alias (tn1) and then use the array_agg function on the id field of the second table alias. Finally, for the array_agg function to work properly, you will group the results by the tn1.id field. This will produce a result set that contains the the id of a record and an array of all the id's that fit the join conditions.

select tn1.id,
       array_agg(tn2.id) as duplicate_entries, 
from table_name tn1 join table_name tn2 on 
    tn1.year = tn2.year 
    and tn1.sid = tn2.sid 
    and tn1.user_id = tn2.user_id 
    and tn1.cid = tn2.cid
    and tn1.id <> tn2.id
group by tn1.id;

Obviously, id's that will be in the duplicate_entries array for one id, will also have their own entries in the result set. You will have to use this result set to decide which id you want to become the source of 'truth.' The one record that shouldn't get deleted. Maybe you could do something like this:

with dupe_set as (
select tn1.id,
       array_agg(tn2.id) as duplicate_entries, 
from table_name tn1 join table_name tn2 on 
    tn1.year = tn2.year 
    and tn1.sid = tn2.sid 
    and tn1.user_id = tn2.user_id 
    and tn1.cid = tn2.cid
    and tn1.id <> tn2.id
group by tn1.id
order by tn1.id asc)
select ds.id from dupe_set ds where not exists 
 (select de from unnest(ds.duplicate_entries) as de where de < ds.id)

Selects the lowest number ID's that have duplicates (assuming the ID is increasing int PK). These would be the ID's that you would keep around.

This has been discussed on SO multiple times. Here are a few links to get you started:
