You can use the ImageLocation property of pictureBox1:

pictureBox1.ImageLocation = @"C:\Users\MSI\Desktop\MYAPP\Slider\Slider\bt1.jpg";

Yes. But if you do add the code outside it most likely will not be the end of the world since most browsers will fix it, but it is still a bad practice to get into.

The behaviour of datetime.datetime.utcnow() returning UTC time as naive datetime object is obviously problematic and must be fixed. It can lead to unexpected result if your system local timezone is not UTC, since datetime library presume naive datetime object to represent system local time. For example, datetime.datetime.utcnow().timestaamp() gives timestamp of 4 hours ahead from correct value on my computer. Also, as of python 3.6, datetime.astimezone() can be called on naive datetime instances, but datetime.datetime.utcnow().astimezone(any_timezone) gives wrong result unless your system local timezone is UTC.

You can simply do:

Serial.println(n);

which will convert n to an ASCII string automatically. See the documentation for Serial.println().

I'm using Visual Studio with Parallels/Win 7 on a MacBook laptop keyboard and the only thing that worked was Fn + Enter/Return (that's the Mac shortcut for Insert).

Try trimming the string to make sure there is no extra white space:

Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE TRIM(name) = '"+name.trim()+"'", null);

Also use c.moveToFirst() like @thinksteep mentioned.

This is a complete code for select statements.

SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("SELECT column1,column2,column3 FROM table ", null);
if (c.moveToFirst()){
    do {
        // Passing values 
        String column1 = c.getString(0);
        String column2 = c.getString(1);
        String column3 = c.getString(2); 
        // Do something Here with values
    } while(c.moveToNext());
}
c.close();
db.close();

I encountered a similar problem. And I found the solution to be totally unrelated to the error. The trick was renaming the assembly name. Solution: VS 2013 -> Project properties -> Application tab -> AssemblyName property changed to new name < 25 chars

Here is maybe a more elegant and flexible solution with 'resolve' configuration property and 'promises' enabling eventual data loading on routing and routing rules depending on data.

You specify a function in 'resolve' in routing config and in the function load and check data, do all redirects. If you need to load data, you return a promise, if you need to do redirect - reject promise before that. All details can be found on $routerProvider and $q documentation pages.

'use strict';

var app = angular.module('app', [])
    .config(['$routeProvider', function($routeProvider) {
        $routeProvider
            .when('/', {
                templateUrl: "login.html",
                controller: LoginController
            })
            .when('/private', {
                templateUrl: "private.html",
                controller: PrivateController,
                resolve: {
                    factory: checkRouting
                }
            })
            .when('/private/anotherpage', {
                templateUrl:"another-private.html",
                controller: AnotherPriveController,
                resolve: {
                    factory: checkRouting
                }
            })
            .otherwise({ redirectTo: '/' });
    }]);

var checkRouting= function ($q, $rootScope, $location) {
    if ($rootScope.userProfile) {
        return true;
    } else {
        var deferred = $q.defer();
        $http.post("/loadUserProfile", { userToken: "blah" })
            .success(function (response) {
                $rootScope.userProfile = response.userProfile;
                deferred.resolve(true);
            })
            .error(function () {
                deferred.reject();
                $location.path("/");
             });
        return deferred.promise;

};

For russian-speaking folks there is a post on habr "??????? ????????? ???????? ? AngularJS."

Will it warn you if you pass a 32-bit unsigned integer to a %lu format? It should be fine since the conversion is well-defined and doesn't lose any information.

I've heard that some platforms define macros in <inttypes.h> that you can insert into the format string literal but I don't see that header on my Windows C++ compiler, which implies it may not be cross-platform.

I believe the cleanest way to strip a single character from a string with bash is:

echo ${COMPANY_NAME:: -1}

but I haven't been able to embed the grep piece within the curly braces, so your particular task becomes a two-liner:

COMPANY_NAME=$(grep "company_name" file.txt); COMPANY_NAME=${COMPANY_NAME:: -1} 

This will strip any character, semicolon or not, but can get rid of the semicolon specifically, too. To remove ALL semicolons, wherever they may fall:

echo ${COMPANY_NAME/;/}

To remove only a semicolon at the end:

echo ${COMPANY_NAME%;}

Or, to remove multiple semicolons from the end:

echo ${COMPANY_NAME%%;}

For great detail and more on this approach, The Linux Documentation Project covers a lot of ground at http://tldp.org/LDP/abs/html/string-manipulation.html

Many years later there seems to still be a usability problem with the Python logger. Here's some explanations with examples:

import logging
# This sets the root logger to write to stdout (your console).
# Your script/app needs to call this somewhere at least once.
logging.basicConfig()

# By default the root logger is set to WARNING and all loggers you define
# inherit that value. Here we set the root logger to NOTSET. This logging
# level is automatically inherited by all existing and new sub-loggers
# that do not set a less verbose level.
logging.root.setLevel(logging.NOTSET)

# The following line sets the root logger level as well.
# It's equivalent to both previous statements combined:
logging.basicConfig(level=logging.NOTSET)


# You can either share the `logger` object between all your files or the
# name handle (here `my-app`) and call `logging.getLogger` with it.
# The result is the same.
handle = "my-app"
logger1 = logging.getLogger(handle)
logger2 = logging.getLogger(handle)
# logger1 and logger2 point to the same object:
# (logger1 is logger2) == True


# Convenient methods in order of verbosity from highest to lowest
logger.debug("this will get printed")
logger.info("this will get printed")
logger.warning("this will get printed")
logger.error("this will get printed")
logger.critical("this will get printed")


# In large applications where you would like more control over the logging,
# create sub-loggers from your main application logger.
component_logger = logger.getChild("component-a")
component_logger.info("this will get printed with the prefix `my-app.component-a`")

# If you wish to control the logging levels, you can set the level anywhere 
# in the hierarchy:
#
# - root
#   - my-app
#     - component-a
#

# Example for development:
logger.setLevel(logging.DEBUG)

# If that prints too much, enable debug printing only for your component:
component_logger.setLevel(logging.DEBUG)


# For production you rather want:
logger.setLevel(logging.WARNING)

A common source of confusion comes from a badly initialised root logger. Consider this:

import logging
log = logging.getLogger("myapp")
log.warning("woot")
logging.basicConfig()
log.warning("woot")

Output:

woot
WARNING:myapp:woot

Depending on your runtime environment and logging levels, the first log line (before basic config) might not show up anywhere.

The answer is:

driver.find_element_by_class_name("ctsymbol").text

A general answer

select * from [dbo].[SplitString]('1,2',',') -- Will work 

but

select [dbo].[SplitString]('1,2',',')  -- will not work and throws this error

Some performance measurements, using timeit instead of trying to do it manually with time.

First, Apple 2.7.2 64-bit:

In [37]: %timeit collections.deque((x for x in xrange(10000000) if x%4 == 0), maxlen=0)
1 loops, best of 3: 1.05 s per loop

Now, python.org 3.3.0 64-bit:

In [83]: %timeit collections.deque((x for x in range(10000000) if x%4 == 0), maxlen=0)
1 loops, best of 3: 1.32 s per loop

In [84]: %timeit collections.deque((x for x in xrange(10000000) if x%4 == 0), maxlen=0)
1 loops, best of 3: 1.31 s per loop

In [85]: %timeit collections.deque((x for x in iter(range(10000000)) if x%4 == 0), maxlen=0) 
1 loops, best of 3: 1.33 s per loop

Apparently, 3.x range really is a bit slower than 2.x xrange. And the OP's xrange function has nothing to do with it. (Not surprising, as a one-time call to the __iter__ slot isn't likely to be visible among 10000000 calls to whatever happens in the loop, but someone brought it up as a possibility.)

But it's only 30% slower. How did the OP get 2x as slow? Well, if I repeat the same tests with 32-bit Python, I get 1.58 vs. 3.12. So my guess is that this is yet another of those cases where 3.x has been optimized for 64-bit performance in ways that hurt 32-bit.

But does it really matter? Check this out, with 3.3.0 64-bit again:

In [86]: %timeit [x for x in range(10000000) if x%4 == 0]
1 loops, best of 3: 3.65 s per loop

So, building the list takes more than twice as long than the entire iteration.

And as for "consumes much more resources than Python 2.6+", from my tests, it looks like a 3.x range is exactly the same size as a 2.x xrange—and, even if it were 10x as big, building the unnecessary list is still about 10000000x more of a problem than anything the range iteration could possibly do.

And what about an explicit for loop instead of the C loop inside deque?

In [87]: def consume(x):
   ....:     for i in x:
   ....:         pass
In [88]: %timeit consume(x for x in range(10000000) if x%4 == 0)
1 loops, best of 3: 1.85 s per loop

So, almost as much time wasted in the for statement as in the actual work of iterating the range.

If you're worried about optimizing the iteration of a range object, you're probably looking in the wrong place.

Meanwhile, you keep asking why xrange was removed, no matter how many times people tell you the same thing, but I'll repeat it again: It was not removed: it was renamed to range, and the 2.x range is what was removed.

Here's some proof that the 3.3 range object is a direct descendant of the 2.x xrange object (and not of the 2.x range function): the source to 3.3 range and 2.7 xrange. You can even see the change history (linked to, I believe, the change that replaced the last instance of the string "xrange" anywhere in the file).

So, why is it slower?

Well, for one, they've added a lot of new features. For another, they've done all kinds of changes all over the place (especially inside iteration) that have minor side effects. And there'd been a lot of work to dramatically optimize various important cases, even if it sometimes slightly pessimizes less important cases. Add this all up, and I'm not surprised that iterating a range as fast as possible is now a bit slower. It's one of those less-important cases that nobody would ever care enough to focus on. No one is likely to ever have a real-life use case where this performance difference is the hotspot in their code.

I'll throw my hat in here:

(as part of a static class, as this snippet is two extensions)

//hex encoding of the hash, in uppercase.
public static string Sha1Hash (this string str)
{
    byte[] data = UTF8Encoding.UTF8.GetBytes (str);
    data = data.Sha1Hash ();
    return BitConverter.ToString (data).Replace ("-", "");
}
// Do the actual hashing
public static byte[] Sha1Hash (this byte[] data)
{
    using (SHA1Managed sha1 = new SHA1Managed ()) {
    return sha1.ComputeHash (data);
}

For Windows users, you can add a system environment variable named _JAVA_OPTIONS, and set the heap size values there. The JVM should be able to grab the virtual machine options from _JAVA_OPTIONS.

According to the LanguageManual, you can use unix_timestamp() to get the "current time stamp using the default time zone." If you need to convert that to something more human-readable, you can use from_unixtime(unix_timestamp()).

Hope that helps.

Hardware

I'm sorry, but upgrading development station to SSD and tons of ram has probably a bigger influence than points below combined.

Tools versions

Increasing build performance has major priority for the development teams, so make sure you are using latest Gradle and Android Gradle Plugin.

Configuration File

Create a file named gradle.properties in whatever directory applies:

• /home/<username>/.gradle/ (Linux)
• /Users/<username>/.gradle/ (Mac)
• C:\Users\<username>\.gradle (Windows)

Append:

# IDE (e.g. Android Studio) users:
# Settings specified in this file will override any Gradle settings
# configured through the IDE.

# For more details on how to configure your build environment visit
# http://www.gradle.org/docs/current/userguide/build_environment.html

# The Gradle daemon aims to improve the startup and execution time of Gradle.
# When set to true the Gradle daemon is to run the build.
# TODO: disable daemon on CI, since builds should be clean and reliable on servers
org.gradle.daemon=true

# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
# https://medium.com/google-developers/faster-android-studio-builds-with-dex-in-process-5988ed8aa37e#.krd1mm27v
org.gradle.jvmargs=-Xmx5120m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
org.gradle.parallel=true

# Enables new incubating mode that makes Gradle selective when configuring projects. 
# Only relevant projects are configured which results in faster builds for large multi-projects.
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:configuration_on_demand
org.gradle.configureondemand=true

# Set to true or false to enable or disable the build cache. 
# If this parameter is not set, the build cache is disabled by default.
# http://tools.android.com/tech-docs/build-cache
android.enableBuildCache=true

Gradle properties works local if you place them at projectRoot\gradle.properties and globally if you place them at user_home\.gradle\gradle.properties. Properties applied if you run gradle tasks from console or directly from idea:

IDE Settings

It is possible to tweak Gradle-IntelliJ integration from the IDE settings GUI. Enabling "offline work" (check answer from yava below) will disable real network requests on every "sync gradle file".

Native multi-dex

One of the slowest steps of the apk build is converting java bytecode into single dex file. Enabling native multidex (minSdk 21 for debug builds only) will help the tooling to reduce an amount of work (check answer from Aksel Willgert below).

Dependencies

Prefer @aar dependencies over library sub-projects.

Search aar package on mavenCentral, jCenter or use jitpack.io to build any library from github. If you are not editing sources of the dependency library you should not build it every time with your project sources.

Antivirus

Consider to exclude project and cache files from antivirus scanning. This is obviously a trade off with security (don't try this at home!). But if you switch between branches a lot, then antivirus will rescan files before allowing gradle process to use it, which slows build time (in particular AndroidStudio sync project with gradle files and indexing tasks). Measure build time and process CPU with and without antivirus enabled to see if it is related.

Profiling a build

Gradle has built-in support for profiling projects. Different projects are using a different combination of plugins and custom scripts. Using --profile will help to find bottlenecks.

I added the following to @PreDestroy method in my CDI @ApplicationScoped bean, and when I shutdown TomEE 1.6.0 (tomcat7.0.39, as of today), it clears the thread locals.

First you have to add an ArrayList to the Map

ArrayList<Item> al = new ArrayList<Item>();

Items.add("theKey", al); 

then you can add an item to the ArrayLIst that is inside the Map like this:

Items.get("theKey").add(item);  // item is an object of type Item

I don't like ActionView based solutions, my idea is:

1. create a layout with TextView, that TextView will be populated by application

2. when you need to draw a MenuItem:

   2.1. inflate layout

   2.2. call measure() & layout() (otherwise view will be 0px x 0px, it's too small for most use cases)

   2.3. set the TextView's text

   2.4. make "screenshot" of the view

   2.6. set MenuItem's icon based on bitmap created on 2.4

3. profit!

so, result should be something like

1. create layout here is a simple example

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/counterPanel"
    android:layout_width="32dp"
    android:layout_height="32dp"
    android:background="@drawable/ic_menu_gallery">
    <RelativeLayout
        android:id="@+id/counterValuePanel"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >

        <ImageView
            android:id="@+id/counterBackground"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/unread_background" />

        <TextView
            android:id="@+id/count"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="1"
            android:textSize="8sp"
            android:layout_centerInParent="true"
            android:textColor="#FFFFFF" />
    </RelativeLayout>
</FrameLayout>

@drawable/unread_background is that green TextView's background, @drawable/ic_menu_gallery is not really required here, it's just to preview layout's result in IDE.

2. add code into onCreateOptionsMenu/onPrepareOptionsMenu

   @Override
   public boolean onCreateOptionsMenu(Menu menu) {
       getMenuInflater().inflate(R.menu.menu_main, menu);
   
       MenuItem menuItem = menu.findItem(R.id.testAction);
       menuItem.setIcon(buildCounterDrawable(count, R.drawable.ic_menu_gallery));
   
       return true;
   }
   

3. Implement build-the-icon method:

   private Drawable buildCounterDrawable(int count, int backgroundImageId) {
       LayoutInflater inflater = LayoutInflater.from(this);
       View view = inflater.inflate(R.layout.counter_menuitem_layout, null);
       view.setBackgroundResource(backgroundImageId);
   
       if (count == 0) {
           View counterTextPanel = view.findViewById(R.id.counterValuePanel);
           counterTextPanel.setVisibility(View.GONE);
       } else {
           TextView textView = (TextView) view.findViewById(R.id.count);
           textView.setText("" + count);
       }
   
       view.measure(
               View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED),
               View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
       view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
   
       view.setDrawingCacheEnabled(true);
       view.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH);
       Bitmap bitmap = Bitmap.createBitmap(view.getDrawingCache());
       view.setDrawingCacheEnabled(false);
   
       return new BitmapDrawable(getResources(), bitmap);
   }
   

The complete code is here: https://github.com/cvoronin/ActionBarMenuItemCounter

Actually, I think the problem is that your variable "lines" is bad. You defined lines as a tuple, but I believe that write() requires a string. All you have to change is your commas into pluses (+).

nl = "\n"
lines = line1+nl+line2+nl+line3+nl
textdoc.writelines(lines)

should work.

Just spicing up the shell script above to delete older files but with logging and calculation of elapsed time

#!/bin/bash

path="/data/backuplog/"
timestamp=$(date +%Y%m%d_%H%M%S)    
filename=log_$timestamp.txt    
log=$path$filename
days=7

START_TIME=$(date +%s)

find $path -maxdepth 1 -name "*.txt"  -type f -mtime +$days  -print -delete >> $log

echo "Backup:: Script Start -- $(date +%Y%m%d_%H%M)" >> $log


... code for backup ...or any other operation .... >> $log


END_TIME=$(date +%s)

ELAPSED_TIME=$(( $END_TIME - $START_TIME ))


echo "Backup :: Script End -- $(date +%Y%m%d_%H%M)" >> $log
echo "Elapsed Time ::  $(date -d 00:00:$ELAPSED_TIME +%Hh:%Mm:%Ss) "  >> $log

The code adds a few things.

• log files named with a timestamp
• log folder specified
• find looks for *.txt files only in the log folder
• type f ensures you only deletes files
• maxdepth 1 ensures you dont enter subfolders
• log files older than 7 days are deleted ( assuming this is for a backup log)
• notes the start / end time
• calculates the elapsed time for the backup operation...

Note: to test the code, just use -print instead of -print -delete. But do check your path carefully though.

Note: Do ensure your server time is set correctly via date - setup timezone/ntp correctly . Additionally check file times with 'stat filename'

Note: mtime can be replaced with mmin for better control as mtime discards all fractions (older than 2 days (+2 days) actually means 3 days ) when it deals with getting the timestamps of files in the context of days

-mtime +$days  --->  -mmin  +$((60*24*$days))

You have strange expectations. If you gave the chain of arguments that led you to them, we might spot the flaw in them. As it is, I can only give a short primer on generics, hoping to touch on the points you might have misunderstood.

ArrayList<? extends Object> is an ArrayList whose type parameter is known to be Object or a subtype thereof. (Yes, extends in type bounds has a meaning other than direct subclass). Since only reference types can be type parameters, this is actually equivalent to ArrayList<?>.

That is, you can put an ArrayList<String> into a variable declared with ArrayList<?>. That's why a1.add(3) is a compile time error. a1's declared type permits a1 to be an ArrayList<String>, to which no Integer can be added.

Clearly, an ArrayList<?> is not very useful, as you can only insert null into it. That might be why the Java Spec forbids it:

It is a compile-time error if any of the type arguments used in a class instance creation expression are wildcard type arguments

ArrayList<ArrayList<?>> in contrast is a functional data type. You can add all kinds of ArrayLists into it, and retrieve them. And since ArrayList<?> only contains but is not a wildcard type, the above rule does not apply.

You can do something like this.

function addRow() {
  const div = document.createElement('div');

  div.className = 'row';

  div.innerHTML = `
    <input type="text" name="name" value="" />
    <input type="text" name="value" value="" />
    <label> 
      <input type="checkbox" name="check" value="1" /> Checked? 
    </label>
    <input type="button" value="-" onclick="removeRow(this)" />
  `;

  document.getElementById('content').appendChild(div);
}

function removeRow(input) {
  document.getElementById('content').removeChild(input.parentNode);
}

select 
  id,
  case 
    when report_type = 'P' 
    then amount 
    when report_type = 'N' 
    then -amount 
    else null 
  end
from table

Here is a complete example

#include <thread>
#include <iostream>

class Wrapper {
   public:
      void member1() {
          std::cout << "i am member1" << std::endl;
      }
      void member2(const char *arg1, unsigned arg2) {
          std::cout << "i am member2 and my first arg is (" << arg1 << ") and second arg is (" << arg2 << ")" << std::endl;
      }
      std::thread member1Thread() {
          return std::thread([=] { member1(); });
      }
      std::thread member2Thread(const char *arg1, unsigned arg2) {
          return std::thread([=] { member2(arg1, arg2); });
      }
};
int main(int argc, char **argv) {
   Wrapper *w = new Wrapper();
   std::thread tw1 = w->member1Thread();
   std::thread tw2 = w->member2Thread("hello", 100);
   tw1.join();
   tw2.join();
   return 0;
}

Compiling with g++ produces the following result

g++ -Wall -std=c++11 hello.cc -o hello -pthread

i am member1
i am member2 and my first arg is (hello) and second arg is (100)

The ViewBag is an System.Dynamic.ExpandoObject as suggested. The properties in the ViewBag are essentially KeyValue pairs, where you access the value by the key. In this sense these are equivalent:

ViewBag.Foo = "Bar";
ViewBag["Foo"] = "Bar";

For me a noop on table has been enough (was already InnoDB):

ALTER TABLE $tbl ENGINE=InnoDB;

nnoremap <silent> <Esc><Esc> <Esc>:nohlsearch<CR><Esc>

I'd wrap the dictionary in another class:

public class MyListDictionary
{

    private Dictionary<string, List<string>> internalDictionary = new Dictionary<string,List<string>>();

    public void Add(string key, string value)
    {
        if (this.internalDictionary.ContainsKey(key))
        {
            List<string> list = this.internalDictionary[key];
            if (list.Contains(value) == false)
            {
                list.Add(value);
            }
        }
        else
        {
            List<string> list = new List<string>();
            list.Add(value);
            this.internalDictionary.Add(key, list);
        }
    }

}

Local storage: It keeps store the user information data without expiration date this data will not be deleted when user closed the browser windows it will be available for day, week, month and year.

//Set the value in a local storage object
localStorage.setItem('name', myName);

//Get the value from storage object
localStorage.getItem('name');

//Delete the value from local storage object
localStorage.removeItem(name);//Delete specifice obeject from local storege
localStorage.clear();//Delete all from local storege

Session Storage: It is same like local storage date except it will delete all windows when browser windows closed by a web user.

//set the value to a object in session storege
sessionStorage.myNameInSession = "Krishna";

I use the FALLBACK option in the HTML5 cache manifest to check if my html5 app is online or offline by:

FALLBACK:
/online.txt /offline.txt

In the html page i use javascript tot read the contents of the online/offline txt file:

<script>$.get( "urlto/online.txt", function( data ) {
$( ".result" ).html( data );
alert( data );
});</script>

When offline the script will read the contents of the offline.txt. Based on the text in the files you can detect if the webpage is online of offline.

Following the Jenkins wiki, you'll have to:

• Install a fresh Jenkins instance on the new server
• Be sure the old and the new Jenkins instances are stopped
• Archive all the content of the JENKINS_HOME of the old Jenkins instance
• Extract the archive into the new JENKINS_HOME directory
• Launch the new Jenkins instance
• Do not forget to change documentation/links to your new instance of Jenkins :)
• Do not forget to change the owner of the new Jenkins files : chown -R jenkins:jenkins $JENKINS_HOME

JENKINS_HOME is by default located in ~/.jenkins on a Linux installation, yet to exactly find where it is located, go on the http://your_jenkins_url/configure page and check the value of the first parameter: Home directory; this is the JENKINS_HOME.

If SET time_zone or SET GLOBAL time_zone does not work, you can change as below:

• Change timezone system, example: ubuntu... $ sudo dpkg-reconfigure tzdata

• Restart the server or you can restart apache2 and mysql (/etc/init.d/mysql restart)

For Ubuntu and running android-studio run to install the packages (these are not installed by default):

android update sdk

You need to tell Eclipse which JDK/JRE's you have installed and where they are located.

This is somewhat burried in the Eclipse preferences: In the Window-Menu select "Preferences". In the Preferences Tree, open the Node "Java" and select "Installed JRE's". Then click on the "Add"-Button in the Panel and select "Standard VM", "Next" and for "JRE Home" click on the "Directory"-Button and select the top level folder of the JDK you want to add.

Its easier than the description may make it look.

This is what helped me. My navigation bar is in the body tag. Entire code for navigation bar is in nav.html file (without any html or body tag, only the code for navigation bar). In the target page, this goes in the head tag:

<script src="https://code.jquery.com/jquery-1.10.2.js"></script>

Then in the body tag, a container is made with an unique id and a javascript block to load the nav.html into the container, as follows:

<!--Navigation bar-->
<div id="nav-placeholder">

</div>

<script>
$(function(){
  $("#nav-placeholder").load("nav.html");
});
</script>
<!--end of Navigation bar-->

The Problem might be from the driver name for example instead of DRIVER={MySQL ODBC 5.3 Driver} try DRIVER={MySQL ODBC 5.3 Unicode Driver} you can see the name of the driver from administration tool

is just invalid. The component added by the router is added as sibling to <router-outlet> and does not replace it.

You can do something like this:

}_x000D_

.flex>div {_x000D_
  flex: 1 0 50%;_x000D_
}_x000D_
_x000D_
.flex>div:first-child {_x000D_
  flex: 0 1 100%;_x000D_
}

<div class="flex">_x000D_
  <div>Hi</div>_x000D_
  <div>Hello</div>_x000D_
  <div>Hello 2</div>_x000D_
</div>

Here is a demo: http://jsfiddle.net/73574emn/1/

This model relies on the line-wrap after one "row" is full. Since we set the first item's flex-basis to be 100% it fills the first row completely. Special attention on the flex-wrap: wrap;

Providing an actual answer.

What is the difference between .Net Core and Mono?

.NET Core now officially is the future of .NET. It started for most part with a re-write of the ASP.NET MVC framework and console applications, which of course includes server applications. (Since it's Turing-complete and supports interop with C dlls, you could, if you absolutely wanted to, also write your own desktop applications with it, for example through 3rd-party libraries like Avalonia, which were a bit very basic at the time I first wrote this, which meant you were pretty much limited to web or server stuff.) Over time, many APIs have been added to .NET Core, so much so that after version 3.1, .NET Core will jump to version 5.0, be known as .NET 5.0 without the "Core", and that then will be the future of the .NET Framework. What used to be the full .NET Framework will linger around in maintenance mode as Full .NET Framework 4.8.x for a few decades, until it will die (maybe there are still going to be some upgrades, but I doubt it). In other words, .NET Core is the future of .NET, and Full .NET Framework will go the way of the Dodo/Silverlight/WindowsPhone.

The main point of .NET Core, apart from multi-platform support, is to improve performance, and to enable "native compilation"/self-contained-deployment (so you don't need .NET framework/VM installed on the target machine.
On the one hand, this means docker.io support on Linux, and on the other, self-contained deployment is useful in "cloud-computing", since then you can just use whatever version of the dotnet-CORE framework you like, and you don't have to worry about which version(s) of the .NET framework the sysadmin has actually installed.

While the .NET Core runtime supports multiple operating systems and processors, the SDK is a different story. And while the SDK supports multiple OS, ARM support for the SDK is/was still work in progress. .NET Core is supported by Microsoft. Dotnet-Core did not come with WinForms or WPF or anything like that.

• As of version 3.0, WinForms and WPF is also supported by .NET Core, but only on Windows, and only by C#. Not by VB.NET (VB.NET support planned for v5 in 2020). And there is no Forms Designer in .NET Core: it's being shipped with a Visual Studio update later, at an unspecified time.
• WebForms are still not supported by .NET Core, and there are no plans to support them, ever (Blazor is the new kid in town for that).
• .NET Core also comes with System.Runtime, which replaces mscorelib.
• Oftentimes, .NET Core is mixed up with NetStandard, which is a bit of a wrapper around System.Runtime/mscorelib (and some others), that allows you to write libraries that target .NET Core, Full .NET Framework and Xamarin (iOS/Android), all at the same time.
• the .NET Core SDK does not/did not work on ARM, at least not last time I checked.

"The Mono Project" is much older than .NET Core.
Mono is Spanish and means Monkey, and as a side-remark, the name has nothing to do with mononucleosis (hint: you could get a list of staff under http://primates.ximian.com/).
Mono was started in 2005 by Miguel de Icaza (the guy that started GNOME - and a few others) as an implementation of the .NET Framework for Linux (Ximian/SuSe/Novell). Mono includes Web-Forms, Winforms, MVC, Olive, and an IDE called MonoDevelop (also knows as Xamarin Studio or Visual Studio Mac). Basically the equivalent of (OpenJDK) JVM and (OpenJDK) JDK/JRE (as opposed to SUN/Oracle JDK). You can use it to get ASP.NET-WebForms + WinForms + ASP.NET-MVC applications to work on Linux.

Mono is supported by Xamarin (the new company name of what used to be Ximian, when they focused on the Mobile market, instead of the Linux market), and not by Microsoft.
(since Xamarin was bought by Microsoft, that's technically [but not culturally] Microsoft.)
You will usually get your C# stuff to compile on mono, but not the VB.NET stuff.
Mono misses some advanced features, like WSE/WCF and WebParts.
Many of the Mono implementations are incomplete (e.g. throw NotImplementedException in ECDSA encryption), buggy (e.g. ODBC/ADO.NET with Firebird), behave differently than on .NET (for example XML-serialization) or otherwise unstable (ASP.NET MVC) and unacceptably slow (Regex). On the upside, the Mono toolchain also works on ARM.

As far as .NET Core is concerned, when they say cross-platform, don't expect that cross-platform means that you could actually just apt-get install .NET Core on ARM-Linux, like you can with ElasticSearch. You'll have to compile the entire framework from source.
That is, if you have that space (e.g. on a Chromebook, which has a 16 to 32 GB total HD).
It also used to have issues of incompatibility with OpenSSL 1.1 and libcurl.
Those have been rectified in the latest version of .NET Core Version 2.2.
So much for cross-platform.

I found a statement on the official site that said, "Code written for it is also portable across application stacks, such as Mono".

As long as that code doesn't rely on WinAPI-calls, Windows-dll-pinvokes, COM-Components, a case-insensitive file system, the default-system-encoding (codepage) and doesn't have directory separator issues, that's correct. However, .NET Core code runs on .NET Core, and not on Mono. So mixing the two will be difficult. And since Mono is quite unstable and slow (for web applications), I wouldn't recommend it anyway. Try image-processing on .NET core, e.g. WebP or moving GIF or multipage-tiff or writing text on an image, you'll be nastily surprised.

Note:
As of .NET Core 2.0, there is System.Drawing.Common (NuGet), which contains most of the functionality of System.Drawing. It should be more or less feature-complete in .NET-Core 2.1. However, System.Drawing.Common uses GDI+, and therefore won't work on Azure (System.Drawing libraries are available in Azure Cloud Service [basically just a VM], but not in Azure Web App [basically shared hosting?])
So far, System.Drawing.Common works fine on Linux/Mac, but has issues on iOS/Android - if it works at all, there.
Prior to .NET Core 2.0, that is to say sometime mid-February 2017, you could use SkiaSharp for imaging (example) (you still can).
Post .net-core 2.0, you'll notice that SixLabors ImageSharp is the way to go, since System.Drawing is not necessarely secure, and has a lot of potential or real memory leaks, which is why you shouldn't use GDI in web-applications; Note that SkiaSharp is a lot faster than ImageSharp, because it uses native-libraries (which can also be a drawback). Also, note that while GDI+ works on Linux & Mac, that doesn't mean it works on iOS/Android.

Code not written for .NET (non-Core) is not portable to .NET Core.
Meaning, if you want a non-GPL C# library like PDFSharp to create PDF-documents (very commonplace), you're out of luck (at the moment) (not anymore). Never mind ReportViewer control, which uses Windows-pInvokes (to encrypt, create mcdf documents via COM, and to get font, character, kerning, font embedding information, measure strings and do line-breaking, and for actually drawing tiffs of acceptable quality), and doesn't even run on Mono on Linux
(I'm working on that).

Also, code written in .NET Core is not portable to Mono, because Mono lacks the .NET Core runtime libraries (so far).

My goal is to use C#, LINQ, EF7, visual studio to create a website that can be ran/hosted in linux.

EF in any version that I tried so far was so goddamn slow (even on such simple things like one table with one left-join), I wouldn't recommend it ever - not on Windows either.
I would particularly not recommend EF if you have a database with unique-constrains, or varbinary/filestream/hierarchyid columns. (Not for schema-update either.)
And also not in a situation where DB-performance is critical (say 10+ to 100+ concurrent users).
Also, running a website/web-application on Linux will sooner or later mean you'll have to debug it.
There is no debugging support for .NET Core on Linux. (Not anymore, but requires JetBrains Rider.)
MonoDevelop does not (yet) support debugging .NET Core projects.
If you have problems, you're on your own. You'll have to use extensive logging.
Be careful, be advised extensive logging will fill your disk in no time, particularly if your program enters an infinite loop or recursion.
This is especially dangerous if your web-app runs as root, because log-in requires logfile-space - if there's no free space left, you won't be able to login anymore.
(Normally, about 5% of diskspace is reserved for user root [aka administrator on Windows], so at least the administrator can still log in if the disk is almost full. But if your applications run as root, that restriction does not apply for their disk usage, and so their logfiles can use 100% of the remaining free space, so not even the administrator can log in any more.)
It's therefore better not to encrypt that disk, that is, if you value your data/system.

Someone told me that he wanted it to be "in Mono", but I don't know what that means.

It either means he doesn't want to use .NET Core, or he just wants to use C# on Linux/Mac. My guess is he just wants to use C# for a Web-App on Linux. .NET Core is the way to go for that, if you absolutely want to do it in C#. Don't go with "Mono proper"; on the surface, it would seem to work at first - but believe me you will regret it because Mono's ASP.NET MVC isn't stable when your server runs long-term (longer than 1 day) - you have now been warned. See also the "did not complete" references when measuring Mono performance on the techempower benchmarks.

I know I want to use the .Net Core 1.0 framework with the technologies I listed above. He also said he wanted to use "fast cgi". I don't know what that means either.

It means he wants to use a high-performance full-featured WebServer like nginx (Engine-X), possibly Apache.
Then he can run mono/dotnetCore with virtual name based hosting (multiple domain names on the same IP) and/or load-balancing. He can also run other websites with other technologies, without requiring a different port-number on the web-server. It means your website runs on a fastcgi-server, and nginx forwards all web-requests for a certain domain via the fastcgi-protocol to that server. It also means your website runs in a fastcgi-pipeline, and you have to be careful what you do, e.g. you can't use HTTP 1.1 when transmitting files.
Otherwise, files will be garbled at the destination.
See also here and here.

To conclude:
.NET Core at present (2016-09-28) is not really portable, nor is is really cross-platform (in particular the debug-tools).
Nor is native-compilation easy, especially for ARM.
And to me, it also does not look like its development is "really finished", yet.
For example, System.Data.DataTable/DataAdaper.Update is missing... (not anymore with .NET Core 2.0)
Together with the System.Data.Common.IDB* interfaces. (not anymore with .NET Core 1.1)
if there ever was one class that is often used, DataTable/DataAdapter would be it...
Also, the Linux-installer (.deb) fails, at least on my machine, and I'm sure I'm not the only one that has that problem.
Debug, maybe with Visual Studio Code, if you can build it on ARM (I managed to do that - do NOT follow Scott Hanselman's blog-post if you do that - there's a howto in the wiki of VS-Code on github), because they don't offer the executable.
Yeoman also fails. (I guess it has something to do with the nodejs version you installed - VS Code requires one version, Yeoman another... but it should run on the same computer. pretty lame
Never mind that it should run on the node version shipped by default on the OS.
Never mind that there should be no dependency on NodeJS in the first place.
The kestell server is also work in progress.
And judging by my experience with the mono-project, I highly doubt they ever tested .NET Core on FastCGI, or that they have any idea what FastCGI-support means for their framework, let alone that they tested it to make sure "everything works". In fact, I just tried making a fastcgi-application with .NET Core and just realized there is no FastCGI library for .NET Core "RTM"...

So when you're going to run .NET Core "RTM" behind nginx, you can only do it by proxying requests to kestrell (that semi-finished nodeJS-derived web-server) - there's no fastcgi support at present in .NET Core "RTM", AFAIK. Since there is no .net core fastcgi library, and no samples, it's also highly unlikely that anybody did any testing on the framework to make sure fastcgi works as expected.

I also question the performance.
In the (preliminary) techempower-benchmark (round 13), aspnetcore-linux ranks on 25% relative to the best performance, while comparable frameworks like Go (golang) rank at 96.9% of peak performance (and that is when returning plaintext without file-system access only). .NET Core does a little better on JSON-serialization, but it does not look compelling either (go reaches 98.5% of peak, .NET core 65%). That said, it can't possibly be worse than "mono proper".

Also, since it's still relatively new, not all of the major libraries have been ported (yet), and I doubt that some of them will ever be ported.
Imaging support is also questionable at best.
For anything encryption, use BouncyCastle instead.

Can you help me make sense of all these terms and if my expectations are realistic?

I hope i helped you making more sense with all these terms.
As far as your expecations go:
Developing a Linux application without knowing anything about Linux is a really stupid idea in the first place, and it's also bound to fail in some horrible way one way or the other. That said, because Linux comes at no licensing costs, it's a good idea in principle, BUT ONLY IF YOU KNOW WHAT YOU DO.
Developing an application for a platform where you can't debug your application on is another really bad idea.
Developing for fastcgi without knowing what consequences there are is yet another really bad idea.

Doing all these things on a "experimental" platform without any knowledge of that platform's specifics and without debugging support is suicide, if your project is more than just a personal homepage. On the other hand, I guess doing it with your personal homepage for learning purposes would probably be a very good experience - then you get to know what the framework and what the non-framework problems are.
You can for example (programmatically) loop-mount a case-insensitive fat32, hfs or JFS for your application, to get around the case-sensitivity issues (loop-mount not recommended in production).

To summarize
At present (2016-09-28), I would stay away from .NET Core (for production usage). Maybe in one to two years, you can take another look, but probably not before.
If you have a new web-project that you develop, start it in .NET Core, not mono.

If you want a framework that works on Linux (x86/AMD64/ARMhf) and Windows and Mac, that has no dependencies, i.e. only static linking and no dependency on .NET, Java or Windows, use Golang instead. It's more mature, and its performance is proven (Baidu uses it with 1 million concurrent users), and golang has a significantly lower memory footprint. Also golang is in the repositories, the .deb installs without problems, the sourcecode compiles - without requiring changes - and golang (in the meantime) has debugging support with delve and JetBrains Gogland on Linux (and Windows and Mac). Golang's build process (and runtime) also doesn't depend on NodeJS, which is yet another plus.

As far as mono goes, stay away from it.
It is nothing short of amazing how far mono has come, but unfortunately that's no substitute for its performance/scalability and stability issues for production applications.
Also, mono-development is quite dead, they largely only develop the parts relevant to Android and iOS anymore, because that's where Xamarin makes their money.
Don't expect Web-Development to be a first-class Xamarin/mono citizen.
.NET Core might be worth it, if you start a new project, but for existing large web-forms projects, porting over is largely out of the question, the changes required are huge. If you have a MVC-project, the amount of changes might be manageable, if your original application design was sane, which is mostly not the case for most existing so-called "historically grown" applications.

December 2016 Update:
Native compilation has been removed from .NET Core preview, as it is not yet ready...

Seems like they have improved pretty heavily on the raw text-file benchmark, but on the other hand, it's gotten pretty buggy. Also, it further deteriorated in the JSON benchmarks. Curious also that entity framework shall be faster for updates than Dapper - although both at record slowness. This is very unlikely to be true. Looks like there still are more than just a few bugs to hunt.

Also, there seems to be relief coming on the Linux IDE front.
JetBrains released "Project Rider", an early access preview of a C#/.NET Core IDE for Linux (and Mac and Windows), that can handle Visual Studio Project files. Finally a C# IDE that is usable & that isn't slow as hell.

Conclusion: .NET Core still is pre-release quality software as we march into 2017. Port your libraries, but stay away from it for production usage, until framework quality stabilizes.
And keep an eye on Project Rider.

2017 Update
Have migrated my (brother's) homepage to .NET Core for now.
So far, the runtime on Linux seems to be stable enough (at least for small projects) - it survived a load test with ease - mono never did.
Also, it looks like I mixed up .NET-Core-native and .NET-Core-self-contained-deployment. Self-contained deployment works, but it is a bit underdocumented, although it's super easy (the build/publish tools are a bit unstable, yet - if you encounter "Positive number required. - Build FAILED." - run the same command again, and it works).

You can run

dotnet restore -r win81-x64
dotnet build -r win81-x64
dotnet publish -f netcoreapp1.1 -c Release -r win81-x64

Note: As per .NET Core 3, you can publish everything minified as a single file:

dotnet publish -r win-x64 -c Release /p:PublishSingleFile=true
dotnet publish -r linux-x64 -c Release /p:PublishSingleFile=true

However, unlike go, it's not a statically linked executable, but a self-extracting zip file, so when deploying, you might run into problems, especially if the temp directory is locked down by group policy, or some other issues. Works fine for a hello-world program, though. And if you don't minify, the executable size will clock in at something around 100 MB.

And you get a self-contained .exe-file (in the publish directory), which you can move to a Windows 8.1 machine without .NET framework installed and let it run. Nice. It's here that dotNET-Core just starts to get interesting. (mind the gaps, SkiaSharp doesn't work on Windows 8.1 / Windows Server 2012 R2, [yet] - the ecosystem has to catch up first - but interestingly, the Skia-dll-load-fail doesn't crash the entire server/application - so everything else works)

(Note: SkiaSharp on Windows 8.1 is missing the appropriate VC runtime files - msvcp140.dll and vcruntime140.dll. Copy them into the publish-directory, and Skia will work on Windows 8.1.)

August 2017 Update
.NET Core 2.0 released.
Be careful - comes with (huge breaking) changes in authentication...
On the upside, it brought the DataTable/DataAdaper/DataSet classes back, and many more.
Realized .NET Core is still missing support for Apache SparkSQL, because Mobius isn't yet ported. That's bad, because that means no SparkSQL support for my IoT Cassandra Cluster, so no joins...
Experimental ARM support (runtime only, not SDK - too bad for devwork on my Chromebook - looking forward to 2.1 or 3.0).
PdfSharp is now experimentally ported to .NET Core.
JetBrains Rider left EAP. You can now use it to develop & debug .NET Core on Linux - though so far only .NET Core 1.1 until the update for .NET Core 2.0 support goes live.

May 2018 Update
.NET Core 2.1 release imminent. Maybe this will fix NTLM-authentication on Linux (NTLM authentication doesn't work on Linux {and possibly Mac} in .NET-Core 2.0 with multiple authenticate headers, such as negotiate, commonly sent with ms-exchange, and they're apparently only fixing it in v2.1, no bugfix release for 2.0).
But I'm not installing preview releases on my machine. So waiting.
v2.1 is also said to greatly reduce compile times. That would be good.

Also, note that on Linux, .NET Core is 64-Bit only !
There is no, and there will be no, x86-32 version of .NET Core on Linux.
And the ARM port is ARM-32 only. No ARM-64, yet.
And on ARM, you (at present) only have the runtime, not the dotnet-SDK.

And one more thing:
Because .NET-Core uses OpenSSL 1.0, .NET Core on Linux doesn't run on Arch Linux, and by derivation not on Manjaro (the most popular Linux distro by far at this point in time), because Arch Linux uses OpenSSL 1.1. So if you're using Arch Linux, you're out of luck (with Gentoo, too).

Edit:

Latest version of .NET Core 2.2+ supports OpenSSL 1.1. So you can use it on Arch or (k)Ubuntu 19.04+. You might have to use the .NET-Core install script though, because there are no packages, yet.

On the upside, performance has definitely improved:

.NET Core 3:
.NET-Core v 3.0 is said to bring WinForms and WPF to .NET-Core.
However, while WinForms and WPF will be .NET Core, WinForms and WPF in .NET-Core will run on Windows only, because WinForms/WPF will use the Windows-API.

Note:
.NET Core 3.0 is now out (RTM), and there is WinForms and WPF support, but only for C# (on Windows). There is no WinForms-Core-Designer. The designer will, eventually, come with a Visual Studio update, somewhen. WinForms support for VB.NET is not supported, but is planned for .NET 5.0 somewhen in 2020.

PS:

echo "DOTNET_CLI_TELEMETRY_OPTOUT=1" >> /etc/environment
export DOTNET_CLI_TELEMETRY_OPTOUT=1 

If you've used it on windows, you probably never saw this:

The .NET Core tools collect usage data in order to improve your experience.
The data is anonymous and does not include command-line arguments.
The data is collected by Microsoft and shared with the community.
You can opt out of telemetry by setting a DOTNET_CLI_TELEMETRY_OPTOUT environment variable to 1 using your favorite shell.
You can read more about .NET Core tools telemetry @ https://aka.ms/dotnet-cli-telemetry.

I thought I'd mention that I think monodevelop (aka Xamarin Studio, the Mono IDE, or Visual Studio Mac as it is now called on Mac) has evolved quite nicely, and is - in the meantime - largely usable.
However, JetBrains Rider (2018 EAP at this point in time) is definitely a lot nicer and more reliable (and the included decompiler is a life-safer), that is to say, if you develop .NET-Core on Linux or Mac. MonoDevelop does not support Debug-StepThrough on Linux in .NET Core, though, since MS does not license their debugging API dll (except for VisualStudio Mac ... ). However, you can use the Samsung debugger for .NET Core through the .NET Core debugger extension for Samsung Debugger for MonoDevelop

Disclaimer:
I don't use Mac, so I can't say if what I wrote here applies to FreeBSD-Unix based Mac as well. I am refering to the Linux (Debian/Ubuntu/Mint) version of JetBrains Rider, mono, MonoDevelop/VisualStudioMac/XamarinStudio and .NET-Core. Also, Apple is contemplating a move from Intel-processors to self-manufactured ARM(ARM-64?)-based processors, so much of what applies to Mac right now might not apply to Mac in the future (2020+).

Also, when I write "mono is quite unstable and slow", the unstable relates to WinFroms & WebForms applications, specifically executing web-applications via fastcgi or with XSP (on the 4.x version of mono), as well as XML-serialization-handling peculiarities, and the quite-slow relates to WinForms, and regular expressions in particular (ASP.NET-MVC uses regular expressions for routing as well).

When I write about my experience about mono 2.x, 3.x and 4.x, that also does not necessarely mean these issues haven't been resolved by now, or by the time you are reading this, nor that if they are fixed now, that there can't be a regression later that reintroduces any of these bugs/features. Nor does that mean that if you embed the mono-runtime, you'll get the same results as when you use the (dev) system's mono runtime. It also doesn't mean that embedding the mono-runtime (anywhere) is necessarely free.

All that doesn't necessarely mean mono is ill-suited for iOS or Android, or that it has the same issues there. I don't use mono on Android or IOS, so I'm in no positon to say anything about stability, usability, costs and performance on these platforms. Obviously, if you use .NET on Android, you have some other costs considerations to do as well, such as weighting xamarin-costs vs. costs and time for porting existing code to Java. One hears mono on Android and IOS shall be quite good. Take it with a grain of salt. For one, don't expect the default-system-encoding to be the same on android/ios vs. Windows, and don't expect the android filesystem to be case-insensitive, and don't expect any windows fonts to be present.

There are multiple classes that are grouped together as "numeric" classes, the 2 most common of which are double (for double precision floating point numbers) and integer. R will automatically convert between the numeric classes when needed, so for the most part it does not matter to the casual user whether the number 3 is currently stored as an integer or as a double. Most math is done using double precision, so that is often the default storage.

Sometimes you may want to specifically store a vector as integers if you know that they will never be converted to doubles (used as ID values or indexing) since integers require less storage space. But if they are going to be used in any math that will convert them to double, then it will probably be quickest to just store them as doubles to begin with.

Another way to change color of a button if you want to do multiple operations along with color change. Using the Tk().after method and binding a change method allows you to change color and do other operations.

Label.destroy is another example of the after method.

    def export_win():
        //Some Operation
        orig_color = export_finding_graph.cget("background")
        export_finding_graph.configure(background = "green")

        tt = "Exported"
        label = Label(tab1_closed_observations, text=tt, font=("Helvetica", 12))
        label.grid(row=0,column=0,padx=10,pady=5,columnspan=3)

        def change(orig_color):
            export_finding_graph.configure(background = orig_color)

        tab1_closed_observations.after(1000, lambda: change(orig_color))
        tab1_closed_observations.after(500, label.destroy)


    export_finding_graph = Button(tab1_closed_observations, text='Export', command=export_win)
    export_finding_graph.grid(row=6,column=4,padx=70,pady=20,sticky='we',columnspan=3)

You can also revert to the original color.

1. In your project folder, create a “.gdbinit” text file. It will contain your gdb debugger configuration
2. Edit “.gdbinit”, and add the line (without the quotes) : “set new-console on”

3. After building the project right click on the project Debug > “Debug Configurations”, as shown below

4. In the “debugger” tab, ensure the “GDB command file” now points to your “.gdbinit” file. Else, input the path to your “.gdbinit” configuration file :

5. Click “Apply” and “Debug”. A native DOS command line should be launched as shown below

How about using Xcode built-in code snippet library?

Update for Swift:

Many up votes inspired me to update this answer.

The build-in Xcode code snippet library has dispatch_after for only objective-c language. People can also create their own Custom Code Snippet for Swift.

Write this in Xcode.

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, Int64(<#delayInSeconds#> * Double(NSEC_PER_SEC))), dispatch_get_main_queue(), {
        <#code to be executed after a specified delay#>
    })

Drag this code and drop it in the code snippet library area.

Bottom of the code snippet list, there will be a new entity named My Code Snippet. Edit this for a title. For suggestion as you type in the Xcode fill in the Completion Shortcut.

For more info see CreatingaCustomCodeSnippet.

Update Swift 3

Drag this code and drop it in the code snippet library area.

DispatchQueue.main.asyncAfter(deadline: .now() + .seconds(<#delayInSeconds#>)) {
    <#code to be executed after a specified delay#>
}

running

export PATH=$PATH:/c/Users/myusername/AppData/Roaming/npm 

helped.

Make sure your actual username is in the myusername section

Sometimes it is not eligible to set height to pixel values. However, it is possible to show vertical scrollbar through setting height of div to 100% and overflow to auto.

Let me show an example:

<div id="content" style="height: 100%; overflow: auto">
  <p>some text</p>
  <ul>
    <li>text</li>
    .....
    <li>text</li>
</div>

You can do:

t1<- t1[-4:-6,-7:-9]

You have to use the String method .toLowerCase() or .toUpperCase() on both the input and the string you are trying to match it with.

Example:

public static void findPatient() {
    System.out.print("Enter part of the patient name: ");
    String name = sc.nextLine();

    System.out.print(myPatientList.showPatients(name));
}

//the other class
ArrayList<String> patientList;

public void showPatients(String name) {
    boolean match = false;

    for(String matchingname : patientList) {
        if (matchingname.toLowerCase().contains(name.toLowerCase())) {
            match = true;
        }
    }
}

I found the below stuff in ffmpeg Docs. Hope this helps! :)

Reference: http://ffmpeg.org/ffmpeg.html#toc-Generic-options

‘-report’ Dump full command line and console output to a file named program-YYYYMMDD-HHMMSS.log in the current directory. This file can be useful for bug reports. It also implies -loglevel verbose.

Note: setting the environment variable FFREPORT to any value has the same effect.

String[] str = {};

But

return {};

won't work as the type information is missing.

There's IMHO a more convenient way. You can indeed interactively prompt the user for the machine(s) he wants to apply the playbook to thanks to vars_prompt:

---

- hosts: "{{ setupHosts }}"
  vars_prompt:
    - name: "setupHosts"
      prompt: "Which hosts would you like to setup?"
      private: no
  tasks:
    […]

<table border="1"; width=100%>

works for me.

Floating point numbers only have so many significant digits, but they can go much higher. If your app will ever handle large numbers, you will notice the epsilon value should be different.

0.001+0.001 = 0.002 BUT 12,345,678,900,000,000,000,000+1=12,345,678,900,000,000,000,000 if you are using floating point and double. It's not a good representation of money, unless you are damn sure you'll never handle more than a million dollars in this system.

I was needed to solve absolutely the same task. I have divided visually the table using different background colors for different parts. Googling the Internet I've found this page https://support.microsoft.com/kb/2815384. Unfortunately it doesn't solve the issue because ColorIndex refers to some unpredictable value, so if some cells have nuances of one color (for example different values of brightness of the color), the suggested function counts them. The solution below is my fix:

Function CountBgColor(range As range, criteria As range) As Long
    Dim cell As range
    Dim color As Long
    color = criteria.Interior.color
    For Each cell In range
        If cell.Interior.color = color Then
            CountBgColor = CountBgColor + 1
        End If
    Next cell
End Function

I actually used pretty much the same code as you above. My service registration in the manifest is the following

<service android:name=".service.MyService" android:enabled="true">
            <intent-filter android:label="@string/menuItemStartService" >
                <action android:name="it.unibz.bluedroid.bluetooth.service.MY_SERVICE"/>
            </intent-filter>
        </service>

In the service class I created an according constant string identifying the service name like:

public class MyService extends ForeGroundService {
    public static final String MY_SERVICE = "it.unibz.bluedroid.bluetooth.service.MY_SERVICE";
   ...
}

and from the according Activity I call it with

startService(new Intent(MyService.MY_SERVICE));

and stop it with

stopService(new Intent(MyService.MY_SERVICE));

It works perfectly. Try to check your configuration and if you don't find anything strange try to debug whether your stopService get's called properly.

If this is in SQL Server, your syntax is correct; however, you need to reference the COUNT(*) as the Total Count from your nested query. This should give you what you need:

SELECT CASE WHEN TotalCount >0 THEN 'TRUE' ELSE 'FALSE' END FROM
(
  SELECT [Some Column], COUNT(*) TotalCount
  FROM INCIDENTS
  WHERE [Some Column] = 'Target Data'
  GROUP BY [Some Column]
) DerivedTable

Using this, you could assign TotalCount to a variable and then use an IF ELSE statement to execute your INSERT statements:

DECLARE @TotalCount int
SELECT @TotalCount = TotalCount FROM
(
  SELECT [Some Column], COUNT(*) TotalCount
  FROM INCIDENTS
  WHERE [Some Column] = 'Target Data'
  GROUP BY [Some Column]
) DerivedTable
IF @TotalCount > 0
    -- INSERT STATEMENT 1 GOES HERE
ELSE
    -- INSERT STATEMENT 2 GOES HERE

@JaredPar: Yes you can use Shelvesets for reviews but keep in mind that shelvesets can be overwritten by yourself/others and therefore are not long term stable. Therefore for regulatory relevant reviews you should never use a Shelveset as base but rather a checkin (Changeset). For an informal review it is ok but not for a formal (E.g. FTA relevant) review!

In SQL Management Studio, go to Security -> Logins and double click your Login. Choose Server Roles from the left column, and verify that sysadmin is checked.

In my case, I was logged in on an account without that privilege.

HTH!

So if I get it right, on click of a button, you want to open up a modal that lists the values entered by the users followed by submitting it.

For this, you first change your input type="submit" to input type="button" and add data-toggle="modal" data-target="#confirm-submit" so that the modal gets triggered when you click on it:

<input type="button" name="btn" value="Submit" id="submitBtn" data-toggle="modal" data-target="#confirm-submit" class="btn btn-default" />

Next, the modal dialog:

<div class="modal fade" id="confirm-submit" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                Confirm Submit
            </div>
            <div class="modal-body">
                Are you sure you want to submit the following details?

                <!-- We display the details entered by the user here -->
                <table class="table">
                    <tr>
                        <th>Last Name</th>
                        <td id="lname"></td>
                    </tr>
                    <tr>
                        <th>First Name</th>
                        <td id="fname"></td>
                    </tr>
                </table>

            </div>

            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
                <a href="#" id="submit" class="btn btn-success success">Submit</a>
            </div>
        </div>
    </div>
</div>

Lastly, a little bit of jQuery:

$('#submitBtn').click(function() {
     /* when the button in the form, display the entered values in the modal */
     $('#lname').text($('#lastname').val());
     $('#fname').text($('#firstname').val());
});

$('#submit').click(function(){
     /* when the submit button in the modal is clicked, submit the form */
    alert('submitting');
    $('#formfield').submit();
});

You haven't specified what the function validateForm() does, but based on this you should restrict your form from being submitted. Or you can run that function on the form's button #submitBtn click and then load the modal after the validations have been checked.

DEMO

What you have seems to be a string incorrectly decoded from another encoding, likely code page 1252, which is US Windows default. Here's how to reverse, assuming no other loss. One loss not immediately apparent is the non-breaking space (U+00A0) at the end of your string that is not displayed. Of course it would be better to read the data source correctly in the first place, but perhaps the data source was stored incorrectly to begin with.

using System;
using System.Text;

class Program
{
    static void Main(string[] args)
    {
        string junk = "déjÃ\xa0";  // Bad Unicode string

        // Turn string back to bytes using the original, incorrect encoding.
        byte[] bytes = Encoding.GetEncoding(1252).GetBytes(junk);

        // Use the correct encoding this time to convert back to a string.
        string good = Encoding.UTF8.GetString(bytes);
        Console.WriteLine(good);
    }
}

Result:

Neither. You should use bcrypt. The hashes you mention are all optimized to be quick and easy on hardware, and so cracking them share the same qualities. If you have no other choice, at least be sure to use a long salt and re-hash multiple times.

Using bcrypt in PHP 5.5+

PHP 5.5 offers new functions for password hashing. This is the recommend approach for password storage in modern web applications.

// Creating a hash
$hash = password_hash($password, PASSWORD_DEFAULT, ['cost' => 12]);
// If you omit the ['cost' => 12] part, it will default to 10

// Verifying the password against the stored hash  
if (password_verify($password, $hash)) {
    // Success! Log the user in here.
}

If you're using an older version of PHP you really should upgrade, but until you do you can use password_compat to expose this API.

Also, please let password_hash() generate the salt for you. It uses a CSPRNG.

Two caveats of bcrypt

1. Bcrypt will silently truncate any password longer than 72 characters.
2. Bcrypt will truncate after any NUL characters.

(Proof of Concept for both caveats here.)

You might be tempted to resolve the first caveat by pre-hashing your passwords before running them through bcrypt, but doing so can cause your application to run headfirst into the second.

Instead of writing your own scheme, use an existing library written and/or evaluated by security experts.

• Zend\Crypt (part of Zend Framework) offers BcryptSha
• PasswordLock is similar to BcryptSha but it also encrypts the bcrypt hashes with an authenticated encryption library.

TL;DR - Use bcrypt.

There are three unique situations:

• 4 numbers, e.g. Margin="a,b,c,d".
• 2 numbers, e.g. Margin="a,b".
• 1 number, e.g. Margin="a".

4 Numbers

If there are 4 numbers, then its left, top, right, bottom (a clockwise circle starting from the middle left margin). First number is always the "West" like "WPF":

<object Margin="left,top,right,bottom"/>

Example: if we use Margin="10,20,30,40" it generates:

2 Numbers

If there are 2 numbers, then the first is left & right margin thickness, the second is top & bottom margin thickness. First number is always the "West" like "WPF":

<object Margin="a,b"/> // Equivalent to Margin="a,b,a,b".

Example: if we use Margin="10,30", the left & right margin are both 10, and the top & bottom are both 30.

1 Number

If there is 1 number, then the number is repeated (its essentially a border thickness).

<object Margin="a"/> // Equivalent to Margin="a,a,a,a".

Example: if we use Margin="20" it generates:

Update 2020-05-27

Have been working on a large-scale WPF application for the past 5 years with over 100 screens. Part of a team of 5 WPF/C#/Java devs. We eventually settled on either using 1 number (for border thickness) or 4 numbers. We never use 2. It is consistent, and seems to be a good way to reduce cognitive load when developing.

The rule:

All width numbers start on the left (the "West" like "WPF") and go clockwise (if two numbers, only go clockwise twice, then mirror the rest).

An enumeration is something of an inverse-array. What I believe you want is this:

const char * Week[] = { "", "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };  // The blank string at the beginning is so that Sunday is 1 instead of 0.
cout << "Today is " << Week[2] << ", enjoy!";  // Or whatever you'de like to do with it.

Since version 2.11, it's pretty easy, you can use the N stack number instead of saying "stash@{n}". So now instead of using:

git stash apply "stash@{n}"

You can type:

git stash apply n

For example, in your list:

stash@{0}: WIP on design: f2c0c72... Adjust Password Recover Email
stash@{1}: WIP on design: f2c0c72... Adjust Password Recover Email
stash@{2}: WIP on design: eb65635... Email Adjust
stash@{3}: WIP on design: eb65635... Email Adjust

If you want to apply stash@{1} you could type:

git stash apply 1

Otherwise, you can use it even if you have some changes in your directory since 1.7.5.1, but you must be sure the stash won't overwrite your working directory changes if it does you'll get an error:

error: Your local changes to the following files would be overwritten by merge:
        file
Please commit your changes or stash them before you merge.

In versions prior to 1.7.5.1, it refused to work if there was a change in the working directory.

Git release notes:

• Release Notes 2.11

The user always has to say "stash@{$N}" when naming a single element in the default location of the stash, i.e. reflogs in refs/stash. The "git stash" command learned to accept "git stash apply 4" as a short-hand for "git stash apply stash@{4}"

• Release Notes 1.7.5.1

git stash apply" used to refuse to work if there was any change in the working tree, even when the change did not overlap with the change the stash recorded

I think the Class on img tag is better when You use the same style in different structure on Your site. You have to decide when you write less line of CSS code and HTML is more readable.

The auto keyword gets the type from the expression on the right of =. Therefore it will work with any type, the only requirement is to initialize the auto variable when declaring it so that the compiler can deduce the type.

Examples:

auto a = 0.0f;  // a is float
auto b = std::vector<int>();  // b is std::vector<int>()

MyType foo()  { return MyType(); }

auto c = foo();  // c is MyType

I'm not sure you can use a relationship as an Id/PrimaryKey in Hibernate.

On your MaterialApp set debugShowCheckedModeBanner to false.

MaterialApp(
  debugShowCheckedModeBanner: false,
)

The debug banner will also automatically be removed on release build.

Basically, you need to include the Wordpress loop in your search.php template to loop through the search results and show them as part of the template.

Below is a very basic example from The WordPress Theme Search Template and Page Template over at ThemeShaper.

<?php
/**
 * The template for displaying Search Results pages.
 *
 * @package Shape
 * @since Shape 1.0
 */

get_header(); ?>

        <section id="primary" class="content-area">
            <div id="content" class="site-content" role="main">

            <?php if ( have_posts() ) : ?>

                <header class="page-header">
                    <h1 class="page-title"><?php printf( __( 'Search Results for: %s', 'shape' ), '<span>' . get_search_query() . '</span>' ); ?></h1>
                </header><!-- .page-header -->

                <?php shape_content_nav( 'nav-above' ); ?>

                <?php /* Start the Loop */ ?>
                <?php while ( have_posts() ) : the_post(); ?>

                    <?php get_template_part( 'content', 'search' ); ?>

                <?php endwhile; ?>

                <?php shape_content_nav( 'nav-below' ); ?>

            <?php else : ?>

                <?php get_template_part( 'no-results', 'search' ); ?>

            <?php endif; ?>

            </div><!-- #content .site-content -->
        </section><!-- #primary .content-area -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

I had a similar problem when posting to the WebAPI endpoint. By turning the CustomErrors=Off, i was able to see the actual error which is one of the dlls was missing.

You can use the DecimalFormat class.

double d = 3.76628729;

DecimalFormat newFormat = new DecimalFormat("#.##");
double twoDecimal =  Double.valueOf(newFormat.format(d));

You can use preg_replace in this case;

$res = preg_replace("/[^0-9]/", "", "Every 6 Months" );

$res return 6 in this case.

If want also to include decimal separator or thousand separator check this example:

$res = preg_replace("/[^0-9.]/", "", "$ 123.099");

$res returns "123.099" in this case

Include period as decimal separator or thousand separator: "/[^0-9.]/"

Include coma as decimal separator or thousand separator: "/[^0-9,]/"

Include period and coma as decimal separator and thousand separator: "/[^0-9,.]/"

You can use a post-commit hook.

Put the post-commit hook script in the hooks folder, create a wget_folder in your C:\ drive, and put the wget.exe file in this folder. Add the following code in the file called post-commit.bat

SET REPOS=%1   
SET REV=%2

FOR /f "tokens=*" %%a IN (  
'svnlook uuid %REPOS%'  
) DO (  
SET UUID=%%a  
)  

FOR /f "tokens=*" %%b IN (  
'svnlook changed --revision %REV% %REPOS%'  
) DO (  
SET POST=%%b   
)

echo %REPOS% ----- 1>&2

echo %REV% -- 1>&2

echo %UUID% --1>&2

echo %POST% --1>&2

C:\wget_folder\wget ^   
    --header="Content-Type:text/plain" ^   
    --post-data="%POST%" ^   
    --output-document="-" ^   
    --timeout=2 ^     
    http://localhost:9090/job/Test/build/%UUID%/notifyCommit?rev=%REV%    

where Test = name of the job

echo is used to see the value and you can also add exit 2 at the end to know about the issue and whether the post-commit hook script is running or not.

I'm still not sure what the issue was but deleting all certificates and starting over (albeit twice) eventually solved it.

My best guess is that I've missed some small but important detail of the procedure. Unfortunately I can't be any more specific than that.

Today I needed to get the page's request parameters into a associative array so I put together the following, with a little help from my friends. It also handles parameters without an = as true.

With an example:

// URL: http://www.example.com/test.php?abc=123&def&xyz=&something%20else

var _GET = (function() {
    var _get = {};
    var re = /[?&]([^=&]+)(=?)([^&]*)/g;
    while (m = re.exec(location.search))
        _get[decodeURIComponent(m[1])] = (m[2] == '=' ? decodeURIComponent(m[3]) : true);
    return _get;
})();

console.log(_GET);
> Object {abc: "123", def: true, xyz: "", something else: true}
console.log(_GET['something else']);
> true
console.log(_GET.abc);
> 123

This works for my Debian:

$ /usr/sbin/apache2 -v

keytool comes with the Java SDK. You should find it in the directory that contains javac, etc.

In the first one Python has to execute one more operations than necessary(instead of just checking not equal to it has to check if it is not true that it is equal, thus one more operation). It would be impossible to tell the difference from one execution, but if run many times, the second would be more efficient. Overall I would use the second one, but mathematically they are the same

You can use np.logaddexp (which implements the idea in @gg349's answer):

In [33]: d = np.array([[1089, 1093]])

In [34]: e = np.array([[1000, 4443]])

In [35]: log_res = np.logaddexp(-3*d[0,0], -3*d[0,1]) - np.logaddexp(-3*e[0,0], -3*e[0,1])

In [36]: log_res
Out[36]: -266.99999385580668

In [37]: res = exp(log_res)

In [38]: res
Out[38]: 1.1050349147204485e-116

Or you can use scipy.special.logsumexp:

In [52]: from scipy.special import logsumexp

In [53]: res = np.exp(logsumexp(-3*d) - logsumexp(-3*e))

In [54]: res
Out[54]: 1.1050349147204485e-116

Yes, need no network service, because Google Authenticator app won't communicate with the google server, it just keeps synced with the initital secret that your server generate(input into your phone from QR code) while the time pass.

I face the same problem , and after a lot of work and search , I figured out the solution : I just cleaned the project then build the apk. -Build->Clean Project -Build-> Build APK(s) I hope it is useful.....

How about git log --pretty=oneline | wc -l

That should count all the commits from the perspective of your current branch.

You can find it inside the /config folder.

When you eject you get a message like:

I think the easiest solution to this problem is to have the customer to open the csv in excel, and then ctrl + r to replace all comma with whatever identifier you want. This is very easy for the customer and require only one change in your code to read the delimiter of your choice.

I was able to make this work by creating a named range in the current sheet that referred to the table I wanted to reference in the other sheet.

You are not writing your code inside any function, you can return from functions only. Remove return statement and just print the value you want.

It's an abbreviation of Error NO ENTry (or Error NO ENTity), and can actually be used for more than files/directories.

It's abbreviated because C compilers at the dawn of time didn't support more than 8 characters in symbols.

Obviously, the syntax are completely different (Groovy is closest to Java), but I suppose that is not what you are asking for.

If you are interested in using them to script a Java application, Scala is probably not a good choice, as there is no easy way to evaluate it from Java, whereas Groovy is especially suited for that purpose.

All above solutions make table header scroll too... If you want to scroll tbody only then apply this:

tbody {
    height: 100px !important;
    overflow: scroll;
    display:block;
}

Your guess is right: the code is trying to evaluate x**3+2*x-4 immediately. Unfortunately you can't really prevent it from doing so. The good news is that in Python, functions are first-class objects, by which I mean that you can treat them like any other variable. So to fix your function, we could do:

import numpy as np  
import matplotlib.pyplot as plt  

def graph(formula, x_range):  
    x = np.array(x_range)  
    y = formula(x)  # <- note now we're calling the function 'formula' with x
    plt.plot(x, y)  
    plt.show()  

def my_formula(x):
    return x**3+2*x-4

graph(my_formula, range(-10, 11))

If you wanted to do it all in one line, you could use what's called a lambda function, which is just a short function without a name where you don't use def or return:

graph(lambda x: x**3+2*x-4, range(-10, 11))

And instead of range, you can look at np.arange (which allows for non-integer increments), and np.linspace, which allows you to specify the start, stop, and the number of points to use.

div = $("<div>").html("Loading......");
$("body").prepend(div);    

Nice Question. This is the logic I came up with. Tested with few scenarios including 25.

class Program
{

    //Allowable denominations
    const int penny = 1;
    const int nickel = 5;
    const int dime = 10;
    const int quarter = 25;

    const int maxCurrencyLevelForTest =55; //1-n where n<=99

    static void Main(string[] args)
    {         
        int minPenniesNeeded = 0;
        int minNickelsNeeded = 0; 
        int minDimesNeeded = 0; 
        int minQuartersNeeded = 0;


        if (maxCurrencyLevelForTest == penny)
        {
            minPenniesNeeded = 1;
        }
        else if (maxCurrencyLevelForTest < nickel)
        {
            minPenniesNeeded = MinCountNeeded(penny, maxCurrencyLevelForTest);                
        }
        else if (maxCurrencyLevelForTest < dime)
        {
            minPenniesNeeded = MinCountNeeded(penny, nickel - 1);
            minNickelsNeeded = MinCountNeeded(nickel, maxCurrencyLevelForTest);                
        }
        else if (maxCurrencyLevelForTest < quarter)
        {
            minPenniesNeeded = MinCountNeeded(penny, nickel - 1);
            minNickelsNeeded = MinCountNeeded(nickel, dime - 1);
            minDimesNeeded = MinCountNeeded(dime, maxCurrencyLevelForTest);
        }
        else
        {
            minPenniesNeeded = MinCountNeeded(penny, nickel - 1);
            minNickelsNeeded = MinCountNeeded(nickel, dime - 1);
            minDimesNeeded = MinCountNeeded(dime, quarter - 1);

            var maxPossilbleValueWithoutQuarters = (minPenniesNeeded * penny + minNickelsNeeded * nickel + minDimesNeeded * dime);
            if (maxCurrencyLevelForTest > maxPossilbleValueWithoutQuarters)
            {               
                minQuartersNeeded = (((maxCurrencyLevelForTest - maxPossilbleValueWithoutQuarters)-1) / quarter) + 1;
            }
        }


        var minCoinsNeeded = minPenniesNeeded + minNickelsNeeded+minDimesNeeded+minQuartersNeeded;

        Console.WriteLine(String.Format("Min Number of coins needed: {0}", minCoinsNeeded));
        Console.WriteLine(String.Format("Penny: {0} needed", minPenniesNeeded));
        Console.WriteLine(String.Format("Nickels: {0} needed", minNickelsNeeded));
        Console.WriteLine(String.Format("Dimes: {0} needed", minDimesNeeded));
        Console.WriteLine(String.Format("Quarters: {0} needed", minQuartersNeeded));
        Console.ReadLine();
    }

    private static int MinCountNeeded(int denomination, int upperRange)
    {
        int remainder;
        return System.Math.DivRem(upperRange, denomination,out remainder);
    }
}

Some results: When maxCurrencyLevelForTest = 25

Min Number of coins needed: 7
Penny: 4 needed
Nickels: 1 needed
Dimes: 2 needed
Quarters: 0 needed

When maxCurrencyLevelForTest = 99

Min Number of coins needed: 10
Penny: 4 needed
Nickels: 1 needed
Dimes: 2 needed
Quarters: 3 needed

maxCurrencyLevelForTest : 54

Min Number of coins needed: 8
Penny: 4 needed
Nickels: 1 needed
Dimes: 2 needed
Quarters: 1 needed

maxCurrencyLevelForTest : 55

Min Number of coins needed: 9
Penny: 4 needed
Nickels: 1 needed
Dimes: 2 needed
Quarters: 2 needed

maxCurrencyLevelForTest : 79

Min Number of coins needed: 9
Penny: 4 needed
Nickels: 1 needed
Dimes: 2 needed
Quarters: 2 needed

maxCurrencyLevelForTest : 85

Min Number of coins needed: 10
Penny: 4 needed
Nickels: 1 needed
Dimes: 2 needed
Quarters: 3 needed

The code can further be refactored I guess.

0755 = User:rwx Group:r-x World:r-x

0750 = User:rwx Group:r-x World:--- (i.e. World: no access)

r = read
w = write
x = execute (traverse for directories)

Just for the fun, I'm offering an alternative solution using jOOQ and Java 8. Instead of using jOOQ, you could be using any other API that maps JDBC ResultSet to List, such as Spring JDBC or Apache DbUtils, or write your own ResultSetIterator:

jOOQ 3.8 or less

List<Object> list =
DSL.using(connection)
   .fetch("SELECT col1, col2, col3, ...")
   .stream()
   .flatMap(r -> Arrays.stream(r.intoArray()))
   .collect(Collectors.toList());

jOOQ 3.9

List<Object> list =
DSL.using(connection)
   .fetch("SELECT col1, col2, col3, ...")
   .stream()
   .flatMap(Record::intoStream)
   .collect(Collectors.toList());

(Disclaimer, I work for the company behind jOOQ)

select 'abcd' + ltrim(str(1)) + ltrim(str(2))

In the converter of the chosen solution, you should add values.Clone() otherwise the parameters in the command end null

public class YourConverter : IMultiValueConverter
{
    public object Convert(object[] values, ...)
    {
        return values.Clone();
    }

    ...
}

I came across the same issue recently. I had to insert new rows in a document with hidden rows and faced the same issues with you. After some search and some emails in apache poi list, it seems like a bug in shiftrows() when a document has hidden rows.

You can put this view between your views to imitate the line

<View
  android:layout_width="fill_parent"
  android:layout_height="2dp"
  android:background="#c0c0c0"/>

A correct way to do basic auth in Python3 urllib.request with certificate validation follows.

Note that certifi is not mandatory. You can use your OS bundle (likely *nix only) or distribute Mozilla's CA Bundle yourself. Or if the hosts you communicate with are just a few, concatenate CA file yourself from the hosts' CAs, which can reduce the risk of MitM attack caused by another corrupt CA.

To get a fully independent copy of an object you can use the copy.deepcopy() function.

A quick way is to use python command line tool. Simply type import <your module name> You see an error if module is missing.

$ python
Python 2.7.6 (default, Jun 22 2015, 17:58:13) 
>>> import sys
>>> import jocker
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named jocker
$

I ran into the very same problem, tried out really everything that I could think of. Not being a fan of installing anything globally, but eventually had to run npm install -g babel-cli, which solved my problem. Maybe not the answer, but definitely a possible solution...

Not all controls that can be included in a page must be run at the server. For example:

<INPUT type="submit" runat=server />

This is essentially the same as:

<asp:Button runat=server />

Remove the runat=server tag from the first one and you have a standard HTML button that runs in the browser. There are reasons for and against running a particular control at the server, and there is no way for ASP.NET to "assume" what you want based on the HTML markup you include. It might be possible to "infer" the runat=server for the <asp:XXX /> family of controls, but my guess is that Microsoft would consider that a hack to the markup syntax and ASP.NET engine.

For Android 2.0 or later you can use the startForeground() method to start your Service in the foreground.

The documentation says the following:

A started service can use the startForeground(int, Notification) API to put the service in a foreground state, where the system considers it to be something the user is actively aware of and thus not a candidate for killing when low on memory. (It is still theoretically possible for the service to be killed under extreme memory pressure from the current foreground application, but in practice this should not be a concern.)

The is primarily intended for when killing the service would be disruptive to the user, e.g. killing a music player service would stop music playing.

You'll need to supply a Notification to the method which is displayed in the Notifications Bar in the Ongoing section.

This is how I got 1.7 to work with Eclipse. I hope it helps.

1. I Downloaded the latest OpenJDK 1.7 universal (32/64 bits) JDK from Mac OS/X branch from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
2. copied the jdk to /Library/Java/JavaVirtualMachines/ next to the default 1.6.0 one
3. In Eclipse > Preferences > Java > Installed JREs you add a new one, of type MacOS X VM, and set the home as /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home and name Java SE 7 (OpenJDK)
4. Click Finish
5. Set the added JRE as default

that should be it :)

This is my basic understanding. It may well be wrong!

1. Items are watched by passing a function (returning the thing to be watched) to the $watch method.
2. Changes to watched items must be made within a block of code wrapped by the $apply method.
3. At the end of the $apply the $digest method is invoked which goes through each of the watches and checks to see if they changed since last time the $digest ran.
4. If any changes are found then the digest is invoked again until all changes stabilize.

In normal development, data-binding syntax in the HTML tells the AngularJS compiler to create the watches for you and controller methods are run inside $apply already. So to the application developer it is all transparent.

I've searched solution to similar problem and maybe my way will help You and anybody who face with it.

I used SelectedValuePath="id" in XAML DataGrid definition, and programaticaly only thing I have to do is set DataGrid.SelectedValue to desired value.

I know this solution has pros and cons, but in specific case is fast and easy.

If you want to merge the filters (eg. CSV and Excel files), use this formula:

OpenFileDialog of = new OpenFileDialog();
of.Filter = "CSV files (*.csv)|*.csv|Excel Files|*.xls;*.xlsx";

Or if you want to see XML or PDF files in one time use this:

of.Filter = @" XML or PDF |*.xml;*.pdf";

If s is your string:

s.replace(/^[^(]*\(/, "") // trim everything before first parenthesis
 .replace(/\)[^(]*$/, "") // trim everything after last parenthesis
 .split(/\)[^(]*\(/);      // split between parenthesis

To tell from the style of your code snippet, I suppose you were using IPython rather than Jupyter Notebook.

In this issue on GitHub, it was made clear by a member of IPython in 2016 that the display of charts would only work when "only work when it's a Jupyter kernel". Thus, the %matplotlib inline would not work.

I was just having the same issue and suggest you use Jupyter Notebook for the visualization.

    public static void Copy(String SourceFile, String TargetFile)
    {

        FileStream fis = null;
        FileStream fos = null;

            try
            {
                Console.Write("## Try No. " + a + " : (Write from " + SourceFile + " to " + TargetFile + ")\n");

                fis = new FileStream(SourceFile, FileMode.Open, FileAccess.ReadWrite);
                fos = new FileStream(TargetFile, FileMode.Create, FileAccess.ReadWrite);

                int intbuffer = 5242880;
                byte[] b = new byte[intbuffer];

                int i;
                while ((i = fis.Read(b, 0, intbuffer)) > 0)
                {
                    fos.Write(b, 0, i);
                }

                Console.Write("Writing file : " + TargetFile + " is successful.\n");

                break;
            }
            catch (Exception e)
            {
                Console.Write("Writing file : " + TargetFile + " is unsuccessful.\n");
                Console.Write(e);
            }
            finally
            {
                if (fis != null)
                {
                    fis.Close();
                }
                if (fos != null)
                {
                    fos.Close();
                }
            }
    }

The code above will read a big file and write to a new big file. The "intbuffer" value can be set in multiple of 1024. While both source and target file are open, it reads the big file by bytes and write to the new target file by bytes. It will not go out of memory.

If by "cursor speed", you mean the repeat rate when holding down a key - then have a look here: http://hints.macworld.com/article.php?story=20090823193018149

To summarize, open up a Terminal window and type the following command:

defaults write NSGlobalDomain KeyRepeat -int 0

More detail from the article:

Everybody knows that you can get a pretty fast keyboard repeat rate by changing a slider on the Keyboard tab of the Keyboard & Mouse System Preferences panel. But you can make it even faster! In Terminal, run this command:

defaults write NSGlobalDomain KeyRepeat -int 0

Then log out and log in again. The fastest setting obtainable via System Preferences is 2 (lower numbers are faster), so you may also want to try a value of 1 if 0 seems too fast. You can always visit the Keyboard & Mouse System Preferences panel to undo your changes.

You may find that a few applications don't handle extremely fast keyboard input very well, but most will do just fine with it.

Let's say that I want to create the following URL:

https://www.myawesomesite.com/turtles/types?type=1&sort=relevance#section-name

To build this with the Uri.Builder I would do the following.

Uri.Builder builder = new Uri.Builder();
builder.scheme("https")
    .authority("www.myawesomesite.com")
    .appendPath("turtles")
    .appendPath("types")
    .appendQueryParameter("type", "1")
    .appendQueryParameter("sort", "relevance")
    .fragment("section-name");
String myUrl = builder.build().toString();

Cleanest way of saving image locally using request:

const request = require('request');
request('http://link/to/your/image/file.png').pipe(fs.createWriteStream('fileName.png'))

If you need to add authentication token in headers do this:

const request = require('request');
request({
        url: 'http://link/to/your/image/file.png',
        headers: {
            "X-Token-Auth": TOKEN,
        }
    }).pipe(fs.createWriteStream('filename.png'))                    

What you can do is set specific width and height to your iframe (for example these could be equal to your window dimensions) and then applying a scale transformation to it. The scale value will be the ratio between your window width and the dimension you wanted to set to your iframe.

E.g.

<iframe width="1024" height="768" src="http://www.bbc.com" style="-webkit-transform:scale(0.5);-moz-transform-scale(0.5);"></iframe>

If you're just after console logging here's what I'd do:

export default class App extends Component {
  componentDidMount() {
    console.log('I was triggered during componentDidMount')
  }

  render() {
    console.log('I was triggered during render')
    return ( 
      <div> I am the App component </div>
    )
  }
}

Shouldn't be any need for those packages just to do console logging.

ArrayList is newer and 20-30% faster.

If you don't need something explitly apparent in Vector, use ArrayList

Here is way to avoid absolute divs and tables if you know parent's height:

<div class="parent">
    <div class="child"> <a href="#">Home</a>
    </div>
</div>

CSS:

.parent {
    line-height:80px;
    border: 1px solid black;
}
.child {
    line-height:normal;
    display: inline-block;
    vertical-align:bottom;
    border: 1px solid red;
}

I know this question is already answered, a long time ago, but this is for other people that may end up here and are having trouble finding what they need. I had trouble finding an existing plugin that did exactly what I needed, so I wrote my own jQuery UI plugin to accomplish this task. It's based on the combobox example on the jQuery UI site. Hopefully it might help someone.

https://github.com/tmooney3979/jquery.ui.combify

<div class="container">_x000D_
    <div class="row">_x000D_
        <div class="col d-flex justify-content-center">_x000D_
             CenterContent_x000D_
        </div>_x000D_
    </div>_x000D_
</div>

Enable 'flex' for the column as we want & use justify-content-center

Try this:

Dim strFile As String = "yourfile.txt"
Dim fileExists As Boolean = File.Exists(strFile)
Using sw As New StreamWriter(File.Open(strFile, FileMode.OpenOrCreate))
    sw.WriteLine( _
        IIf(fileExists, _
            "Error Message in  Occured at-- " & DateTime.Now, _
            "Start Error Log for today"))
End Using

Download https://github.com/douglascrockford/JSON-js/blob/master/json2.js, include it and do

var json_data = JSON.stringify(obj);

Can use getElementsByTagName

var x = document.getElementsByTagName("title")[0];

alert(x.innerHTML)

// or

alert(x.textContent)

// or

document.querySelector('title')

Edits as suggested by Paul

.button {
    border: none;
    background: url('/forms/up.png') no-repeat top left;
    padding: 2px 8px;
}

If you want to end check whether your sentence ends with "." then you have to add [\.\]$ to the end of your pattern.

I would first want to know what you are trying to accomplish here to need an argument to be passed to new Runnable() or to run(). The usual way should be to have a Runnable object which passes data(str) to its threads by setting member variables before starting. The run() method then uses these member variable values to do execute someFunc()

I have used below code in Angular 9. note that it is using http class instead of normal httpClient.

1. so import Headers from the module, otherwise Headers will be mistaken by typescript headers interface and gives error

   import {Http, Headers, RequestOptionsArgs } from "@angular/http";

2. and in your method use following sample code and it is breaked down for easier understanding.

   let customHeaders = new Headers({ Authorization: "Bearer " + localStorage.getItem("token")});
   const requestOptions: RequestOptionsArgs = { headers: customHeaders };
   return this.http.get("/api/orders", requestOptions);
   

I saw all of the answers which are appropriate only for a single activity but there is my solution which will block screenshot for all of the activities without adding any code to the activity. First of all make an Custom Application class and add a registerActivityLifecycleCallbacks.Then register it in your manifest.

MyApplicationContext.class

public class MyApplicationContext extends Application {
    private  Context context;
    public void onCreate() {
        super.onCreate();
        context = getApplicationContext();
        setupActivityListener();
    }

    private void setupActivityListener() {
        registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
            @Override
            public void onActivityCreated(Activity activity, Bundle savedInstanceState) {
                activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE, WindowManager.LayoutParams.FLAG_SECURE);            }
            @Override
            public void onActivityStarted(Activity activity) {
            }
            @Override
            public void onActivityResumed(Activity activity) {

            }
            @Override
            public void onActivityPaused(Activity activity) {

            }
            @Override
            public void onActivityStopped(Activity activity) {
            }
            @Override
            public void onActivitySaveInstanceState(Activity activity, Bundle outState) {
            }
            @Override
            public void onActivityDestroyed(Activity activity) {
            }
        });
    }



}

Manifest

 <application
        android:name=".MyApplicationContext"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

As noted, you could use a target attribute, but it was technically deprecated in XHTML. That leaves you with using javascript, usually something like parent.window.location.

Use a function in place of MidpointRounding.AwayFromZero:

myRound(1.11125,4)

Answer:- 1.1114

public static Double myRound(Double Value, int places = 1000)
{
    Double myvalue = (Double)Value;
    if (places == 1000)
    {
        if (myvalue - (int)myvalue == 0.5)
        {
            myvalue = myvalue + 0.1;
            return (Double)Math.Round(myvalue);
        }
        return (Double)Math.Round(myvalue);
        places = myvalue.ToString().Substring(myvalue.ToString().IndexOf(".") + 1).Length - 1;
    } if ((myvalue * Math.Pow(10, places)) - (int)(myvalue * Math.Pow(10, places)) > 0.49)
    {
        myvalue = (myvalue * Math.Pow(10, places + 1)) + 1;
        myvalue = (myvalue / Math.Pow(10, places + 1));
    }
    return (Double)Math.Round(myvalue, places);
}

Its still the same concept, you'll need to setup path variable so that windows is aware of the java executable and u can run it from command prompt conveniently

Details from the java's own page: https://java.com/en/download/help/path.xml That article applies to: •Platform(s): Solaris SPARC, Solaris x86, Red Hat Linux, SUSE Linux, Windows 8, Windows 7, Vista, Windows XP, Windows 10

For read-only controls they are the same. For 2 way databinding, using a datasource in which you want to update, insert, etc with declarative databinding, you'll need to use Bind.

Imagine for example a GridView with a ItemTemplate and EditItemTemplate. If you use Bind or Eval in the ItemTemplate, there will be no difference. If you use Eval in the EditItemTemplate, the value will not be able to be passed to the Update method of the DataSource that the grid is bound to.

UPDATE: I've come up with this example:

<%@ Page Language="C#" %>

            AutoGenerateColumns="false" 
            DataSourceID="mySource">
            <Columns>
                <asp:TemplateField>
                    <ItemTemplate>
                        <%# Eval("Name") %>
                    </ItemTemplate>
                    <EditItemTemplate>
                        <asp:TextBox 
                            ID="edtName" 
                            runat="server" 
                            Text='<%# Bind("Name") %>' 
                        />
                    </EditItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
    </form>

    <asp:ObjectDataSource 
        ID="mySource" 
        runat="server"
        SelectMethod="Select" 
        UpdateMethod="Update" 
        TypeName="MyCompany.CustomDataSource" />
</body>
</html>

And here's the definition of a custom class that serves as object data source:

public class CustomDataSource
{
    public class Model
    {
        public string Name { get; set; }
    }

    public IEnumerable<Model> Select()
    {
        return new[] 
        {
            new Model { Name = "some value" }
        };
    }

    public void Update(string Name)
    {
        // This method will be called if you used Bind for the TextBox
        // and you will be able to get the new name and update the
        // data source accordingly
    }

    public void Update()
    {
        // This method will be called if you used Eval for the TextBox
        // and you will not be able to get the new name that the user
        // entered
    }
}

EDIT:

The website is now called appicon.co

I usually use assets.codly.io
It generates the assets locally in your browser, no upload, no download.

What happens after login (to which url the user is redirected) is handled by the AuthenticationSuccessHandler.

This interface (a concrete class implementing it is SavedRequestAwareAuthenticationSuccessHandler) is invoked by the AbstractAuthenticationProcessingFilter or one of its subclasses like (UsernamePasswordAuthenticationFilter) in the method successfulAuthentication.

So in order to have an other redirect in case 3 you have to subclass SavedRequestAwareAuthenticationSuccessHandler and make it to do what you want.

Sometimes (depending on your exact usecase) it is enough to enable the useReferer flag of AbstractAuthenticationTargetUrlRequestHandler which is invoked by SimpleUrlAuthenticationSuccessHandler (super class of SavedRequestAwareAuthenticationSuccessHandler).

<bean id="authenticationFilter"
      class="org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter">
    <property name="filterProcessesUrl" value="/login/j_spring_security_check" />
    <property name="authenticationManager" ref="authenticationManager" />
    <property name="authenticationSuccessHandler">
        <bean class="org.springframework.security.web.authentication.SavedRequestAwareAuthenticationSuccessHandler">
            <property name="useReferer" value="true"/>
        </bean>
    </property>
    <property name="authenticationFailureHandler">
        <bean class="org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler">
            <property name="defaultFailureUrl" value="/login?login_error=t" />
        </bean>
    </property>
</bean>

global is a bit of a misnomer in Python, module_namespace would be more descriptive.

The fully qualified name of foo is file1.foo and the global statement is best shunned as there are usually better ways to accomplish what you want to do. (I can't tell what you want to do from your toy example.)

Typically you'd define this toward the top of a class:

public static final String WELCOME_MESSAGE = "Hello, welcome to the server";

Of course, use the appropriate member visibility (public/private/protected) based on where you use this constant.

You can also do it this way, using structures :

function createCounter () {
    var count = 0;

    return {
        increaseBy: function(nb) {
            count += nb;
        },
        reset: function {
            count = 0;
        }
    }
}

Then :

var counter1 = createCounter();
counter1.increaseBy(4);

For "English locale" file names, this works nicely. I'm using this for sanitizing uploaded file names. The file name is not meant to be linked to anything on disk, it's for when the file is being downloaded hence there are no path checks.

$file_name = preg_replace('/([^\x20-~]+)|([\\/:?"<>|]+)/g', '_', $client_specified_file_name);

Basically it strips all non-printable and reserved characters for Windows and other OSs. You can easily extend the pattern to support other locales and functionalities.

container class has 15px left & right padding, so if you want to remove this padding, use following, because row class has -15px left & right margin.

<div class="container">
  <div class="row">
     <img class='img-responsive' src="#" alt="" />
  </div>
</div>

A good book I'm reading: Professional JavaScript for Web Developers by Nicholas C. Zakas 3rd Edition has the following information regarding JSON Syntax:

"JSON Syntax allows the representation of three types of values".

Regarding the one you're interested in, Arrays it says:

"Arrays are represented in JSON using array literal notation from JavaScript. For example, this is an array in JavaScript:

var values = [25, "hi", true];

You can represent this same array in JSON using a similar syntax:

[25, "hi", true]

Note the absence of a variable or a semicolon. Arrays and objects can be used together to represent more complex collections of data, such as:

{
    "books":
              [

This Array contains a number of objects representing books, Each object has several keys, one of which is "authors", which is another array. Objects and arrays are typically top-level parts of a JSON data structure (even though this is not required) and can be used to create a large number of data structures."

To serialize (convert) a JavaScript object into a JSON string you can use the JSON object stringify() method. For the example from Mark Linus answer:

var cars = [{
    color: 'gray',
    model: '1',
    nOfDoors: 4
    },
    {
    color: 'yellow',
    model: '2',
    nOfDoors: 4
}];

cars is now a JavaScript object. To convert it into a JSON object you could do:

var jsonCars = JSON.stringify(cars);

Which yields:

"[{"color":"gray","model":"1","nOfDoors":4},{"color":"yellow","model":"2","nOfDoors":4}]"

To do the opposite, convert a JSON object into a JavaScript object (this is called parsing), you would use the parse() method. Search for those terms if you need more information... or get the book, it has many examples.

You can use my code here

//Print Button Event Handeler
private void btnPrint_Click(object sender, EventArgs e)
{
    PrintDocument pd = new PrintDocument();
    pd.PrintPage += PrintPage;
    //here to select the printer attached to user PC
    PrintDialog printDialog1 = new PrintDialog();
    printDialog1.Document = pd;
    DialogResult result = printDialog1.ShowDialog();
    if (result == DialogResult.OK)
    {
        pd.Print();//this will trigger the Print Event handeler PrintPage
    }
}

//The Print Event handeler
private void PrintPage(object o, PrintPageEventArgs e)
{
    try
    {
        if (File.Exists(this.ImagePath))
        {
            //Load the image from the file
            System.Drawing.Image img = System.Drawing.Image.FromFile(@"C:\myimage.jpg");

            //Adjust the size of the image to the page to print the full image without loosing any part of it
            Rectangle m = e.MarginBounds;

            if ((double)img.Width / (double)img.Height > (double)m.Width / (double)m.Height) // image is wider
            {
                m.Height = (int)((double)img.Height / (double)img.Width * (double)m.Width);
            }
            else
            {
                m.Width = (int)((double)img.Width / (double)img.Height * (double)m.Height);
            }
            e.Graphics.DrawImage(img, m);
        }
    }
    catch (Exception)
    {

    }
}

@Multipart
@POST(Config.UPLOAD_IMAGE)
Observable<Response<String>> uploadPhoto(@Header("Access-Token") String header, @Part MultipartBody.Part imageFile);

And you can call this api like this:

   public void uploadImage(File file) {
     // create multipart
     RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
    MultipartBody.Part body = MultipartBody.Part.createFormData("image", file.getName(), requestFile);

    // upload
    getViewInteractor().showProfileUploadingProgress();

    Observable<Response<String>> observable = api.uploadPhoto("",body);

    // on Response
    subscribeForNetwork(observable, new ApiObserver<Response<String>>() {
        @Override
        public void onError(Throwable e) {
            getViewInteractor().hideProfileUploadingProgress();
        }

        @Override
        public void onResponse(Response<String> response) {

            if (response.code() != 200) {
                Timber.d("error " + response.code());
                return;
            }
            getViewInteractor().hideProfileUploadingProgress();
            getViewInteractor().onProfileImageUploadSuccess(response.body());

        }
    });

}

If you want to make an OutputStream from an InputStream there is one basic problem. A method writing to an OutputStream blocks until it is done. So the result is available when the writing method is finished. This has 2 consequences:

1. If you use only one thread, you need to wait until everything is written (so you need to store the stream's data in memory or disk).
2. If you want to access the data before it is finished, you need a second thread.

Variant 1 can be implemented using byte arrays or filed. Variant 1 can be implemented using pipies (either directly or with extra abstraction - e.g. RingBuffer or the google lib from the other comment).

Indeed with standard java there is no other way to solve the problem. Each solution is an implementataion of one of these.

There is one concept called "continuation" (see wikipedia for details). In this case basically this means:

• there is a special output stream that expects a certain amount of data
• if the ammount is reached, the stream gives control to it's counterpart which is a special input stream
• the input stream makes the amount of data available until it is read, after that, it passes back the control to the output stream

While some languages have this concept built in, for java you need some "magic". For example "commons-javaflow" from apache implements such for java. The disadvantage is that this requires some special bytecode modifications at build time. So it would make sense to put all the stuff in an extra library whith custom build scripts.

@JorgeGRC Thanks for your answer. One thing though, the "maybe" part is very important. If you do have parameter(s), you must include it/them on your template as well and be sure to specify your locals e.g. updateFn({msg: "Directive Args"}.

I know the answer has already been accepted to this, but I think there might be a slightly more reliable way where you don't necessarily have to know the name of the event beforehand. This only works for native events though as far as I know, not custom ones that have been created by plugins. I opted to omit the use of jQuery to simplify things a little.

let input = document.getElementById('inputId');

Object.getOwnPropertyNames(input)
  .filter(key => key.slice(0, 2) === 'on')
  .map(key => key.slice(2))
  .forEach(eventName => {
    input.addEventListener(eventName, event => {
      console.log(event.type);
      console.log(event);
    });
  });

I hope this helps anyone who reads this.

EDIT

So I saw another question here that was similar, so another suggestion would be to do the following:

monitorEvents(document.getElementById('inputId'));

Regexes can also limit the number of characters.

r = re.compile("^[a-z]{1,15}$")

gives you a regex that only matches if the input is entirely lowercase ASCII letters and 1 to 15 characters long.

AStyle can be customized in great detail for C++ and Java (and others too)

This is a source code formatting tool.

clang-format is a powerful command line tool bundled with the clang compiler which handles even the most obscure language constructs in a coherent way.

It can be integrated with Visual Studio, Emacs, Vim (and others) and can format just the selected lines (or with git/svn to format some diff).

It can be configured with a variety of options listed here.

When using config files (named .clang-format) styles can be per directory - the closest such file in parent directories shall be used for a particular file.

Styles can be inherited from a preset (say LLVM or Google) and can later override different options

It is used by Google and others and is production ready.

Also look at the project UniversalIndentGUI. You can experiment with several indenters using it: AStyle, Uncrustify, GreatCode, ... and select the best for you. Any of them can be run later from a command line.

Uncrustify has a lot of configurable options. You'll probably need Universal Indent GUI (in Konstantin's reply) as well to configure it.

A little bit late, but all the answers were specific to linux.

If you need also unix, then you need this:

char * getExecPath (char * path,size_t dest_len, char * argv0)
{
    char * baseName = NULL;
    char * systemPath = NULL;
    char * candidateDir = NULL;

    /* the easiest case: we are in linux */
    size_t buff_len;
    if (buff_len = readlink ("/proc/self/exe", path, dest_len - 1) != -1)
    {
        path [buff_len] = '\0';
        dirname (path);
        strcat  (path, "/");
        return path;
    }

    /* Ups... not in linux, no  guarantee */

    /* check if we have something like execve("foobar", NULL, NULL) */
    if (argv0 == NULL)
    {
        /* we surrender and give current path instead */
        if (getcwd (path, dest_len) == NULL) return NULL;
        strcat  (path, "/");
        return path;
    }


    /* argv[0] */
    /* if dest_len < PATH_MAX may cause buffer overflow */
    if ((realpath (argv0, path)) && (!access (path, F_OK)))
    {
        dirname (path);
        strcat  (path, "/");
        return path;
    }

    /* Current path */
    baseName = basename (argv0);
    if (getcwd (path, dest_len - strlen (baseName) - 1) == NULL)
        return NULL;

    strcat (path, "/");
    strcat (path, baseName);
    if (access (path, F_OK) == 0)
    {
        dirname (path);
        strcat  (path, "/");
        return path;
    }

    /* Try the PATH. */
    systemPath = getenv ("PATH");
    if (systemPath != NULL)
    {
        dest_len--;
        systemPath = strdup (systemPath);
        for (candidateDir = strtok (systemPath, ":"); candidateDir != NULL; candidateDir = strtok (NULL, ":"))
        {
            strncpy (path, candidateDir, dest_len);
            strncat (path, "/", dest_len);
            strncat (path, baseName, dest_len);

            if (access(path, F_OK) == 0)
            {
                free (systemPath);
                dirname (path);
                strcat  (path, "/");
                return path;
            }
        }
        free(systemPath);
        dest_len++;
    }

    /* again someone has use execve: we dont knowe the executable name; we surrender and give instead current path */
    if (getcwd (path, dest_len - 1) == NULL) return NULL;
    strcat  (path, "/");
    return path;
}

EDITED: Fixed the bug reported by Mark lakata.

Actually, your question is how to write a Higher Order Component (HOC). The main goal of using HOC is preventing copy-pasting. You can write your HOC as a purely functional component or as a class here is an example:

    class Child extends Component {
    render() {
        return (
            <div>
                Child
            </div>
        );
    }
}

If you want to write your parent component as a class-based component:

    class Parent extends Component {
    render() {
        return (
            <div>
                {this.props.children}
            </div>
        );
    }
}

If you want to write your parent as a functional component:

    const Parent=props=>{
    return(
        <div>
            {props.children}
        </div>
    )
}

From the documentation of InetAddress.getByName(String host):

The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address. If a literal IP address is supplied, only the validity of the address format is checked.

So you can use it.

It's for declaring class member variables in PHP4, and is no longer needed. It will work in PHP5, but will raise an E_STRICT warning in PHP from version 5.0.0 up to version 5.1.2, as of when it was deprecated. Since PHP 5.3, var has been un-deprecated and is a synonym for 'public'.

Example usage:

class foo {
    var $x = 'y'; // or you can use public like...
    public $x = 'y'; //this is also a class member variables.
    function bar() {
    }
}

you can also use

<br style="clear:both" />

Using this code you can take input till pressing enter of your keyboard.

char ch[100];
int i;
for (i = 0; ch[i] != '\n'; i++)
{
    scanf("%c ", &ch[i]);
}

To turn OFF scrolling try this:

var current = $(window).scrollTop();
$(window).scroll(function() {
    $(window).scrollTop(current);
});

to reset:

$(window).off('scroll');

I found this;

Excel VBA ComboBox Lists

from here;

vba- Can a combobox present more then one column on it's textbox part?

and this may help;

Populating ComboBoxes VBA

I added a sort of demo here;

Playing with populating boxes.xlsm

The new JS API for this is Object.fromEntries(array of tuples), it works with raw arrays and/or Maps

Here is a version without the "clutter" of other answers and simply does the trick.

static void Main(string[] args)
{

    Console.WriteLine("Enter your number: ");
    int num = Convert.ToInt32(Console.ReadLine());
    bool isPrime = true;
    for (int i = 2; i < num/2; i++)
    {
        if (num % i == 0)
        {
            isPrime = false;
            break;
        }
    }
    if (isPrime)
        Console.WriteLine("It is Prime");
    else
        Console.WriteLine("It is not Prime");
    Console.ReadLine();
}

Do this:

$(document).ready(function(){
    $(".header").click(function(){
        $(this).children(".children").toggle();
    });
   $(".header a").click(function(e) {
        e.stopPropagation();
   });
});

If you want to read more on .stopPropagation(), look here.

It can easilly be done with ArgueJS:

function myFunction ()
{
  arguments = __({myDate: Date, myString: String});
  // do stuff
};

It's probably redundant for me to contribute since I already stated my position in my blog article, but the final paragraph of that article kind of sums things up:

So, in conclusion, learn to love the POCO, and make sure you don’t spread any misinformation about it being the same thing as a DTO. DTOs are simple data containers used for moving data between the layers of an application. POCOs are full fledged business objects with the one requirement that they are Persistence Ignorant (no get or save methods). Lastly, if you haven’t checked out Jimmy Nilsson’s book yet, pick it up from your local university stacks. It has examples in C# and it’s a great read.

BTW, Patrick I read the POCO as a Lifestyle article, and I completely agree, that is a fantastic article. It's actually a section from the Jimmy Nilsson book that I recommended. I had no idea that it was available online. His book really is the best source of information I've found on POCO / DTO / Repository / and other DDD development practices.

If you are starting the script within the command line, then add exit /b to keep CMD opened

You need convert list to numpy array and then reshape:

df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)
   a  b  c
0  1  2  3
1  4  5  6
2  7  8  9

Additionally if someone have a use case where he needs group names before executing search on Regex object he can use:

var regex = new Regex(pattern); // initialized somewhere
// ...
var groupNames = regex.GetGroupNames();

One solution is here:

The solution for this problem is to add the line of code “Application.EnableCancelKey = xlDisabled” in the first line of your macro.. This will fix the problem and you will be able to execute the macro successfully without getting the error message “Code execution has been interrupted”.

But, after I inserted this line of code, I was not able to use Ctrl+Break any more. So it works but not greatly.

If you're using Visual Studio (this might work in Eclipse also, but I never tried) and you copy & paste into Microsoft Word (or any other microsoft product) it will paste the code in whatever color your IDE had. Then you just need to copy the text out of word and into your desired application and it will paste as rich text.

I've only seen this work across Visual Studio to other Microsoft products though so I don't know if it will be any help.

Please search "depends.exe" in google, it's a tiny utility to handle this.

I had the same error and replaced the dot notation with bracket notation to suppress it.

e.g.: obj.name -> obj['name']

You are correct, but note that you can do it the other way around - use Android Wifi tethering that sets up the phone as a base station and connect to said base station from the laptop.

In Chrome and IE9 (and I'm guessing all other browsers too) only the latter will generate a socket connect, the first one will be discarded. (The browser detects this as both requests are sent within one JavaScript "timeslice" in your code above, and discards all but the last request.)

If you instead have some event callback do the second submission (but before the reply is received), the socket of the first request will be cancelled. This is definitely nothing to recommend as the server in that case may well have handled your first request, but you will never know for sure.

I recommend you use/generate a single request which you can transact server-side.

model =list.stream().max(Comparator.comparing(Model::yourSortList)).get();

Here is a much cleaner syntax if using rails 4+

<%= f.text_field :attr, placeholder: "placeholder text" %>

So rails 4+ can now use this syntax instead of the hash syntax

...or alternatively if you only want to show a portion of the time value use "Custom":

timePicker = new DateTimePicker();
timePicker.Format = DateTimePickerFormat.Custom;
timePicker.CustomFormat = "HH:mm"; // Only use hours and minutes
timePicker.ShowUpDown = true;

I had the same issue and correct answer above did not work for me. What I did to resolve it was to go to Build Path->Configure Build Path and under the source tab I removed all the sources (which only had one source) and reconfigured them from there. I ended up removing the project from eclipse and import the maven project again in order to clear up the error.

This can also happen when you disabled MFA. There will be an old long term entry in the AWS credentials.

Edit the file manually with editor of choice, here using vi (please backup before):

vi ~/.aws/credentials

Then remove the [default-long-term] section. As result in a minimal setup there should be one section [default] left with the actual credentials.

[default-long-term]
aws_access_key_id = ...
aws_secret_access_key = ...
aws_mfa_device = ...

Chart JS 2.0

Just set chart.data.labels = [];

For example:

function addData(chart, label, data) {
    chart.data.labels.push(label);
    chart.data.datasets.forEach((dataset) => {
       dataset.data.push(data);
    });
    chart.update();
}

$chart.data.labels = [];

$.each(res.grouped, function(i,o) {
   addData($chart, o.age, o.count);
});
$chart.update();

You can zip the list with itself sans the first element:

a = [5, 7, 11, 4, 5]

for previous, current in zip(a, a[1:]):
    print(previous, current)

This works even if your list has no elements or only 1 element (in which case zip returns an empty iterable and the code in the for loop never executes). It doesn't work on generators, only sequences (tuple, list, str, etc).

If you're using underscore, you can use bind.

E.g.

if (this.options.destroyOnHide) {
     setTimeout(_.bind(this.tip.destroy, this), 1000);
}

My workaround for the webpack version "webpack": "^4.29.6" is very simple.

//package.json
{
...
 "scripts": {
    "build": "webpack --mode production",
    "start": "webpack-dev-server --open --mode development"
  },
}

you can pass --mode parameter with your webpack commnad then in webpack.config.js

 // webpack.config.json
 module.exports = (env,argv) => {
        return {
           ...
           externals: {
            // global app config object
            config: JSON.stringify({
                apiUrl: (argv.mode==="production") ? '/api' : 'localhost:3002/api'
            })
        }
}

And I use baseurl in my code like this

// my api service
import config from 'config';
console.log(config.apiUrl) // like fetch(`${config.apiUrl}/users/user-login`)

Is there a way to handle form post data in a Web Api controller?

The normal approach in ASP.NET Web API is to represent the form as a model so the media type formatter deserializes it. Alternative is to define the actions's parameter as NameValueCollection:

public void Post(NameValueCollection formData)
{
  var value = formData["key"];
}

IIS Mime Type: .woff font/x-woff (not application/x-woff, or application/x-font-woff)

Python 3.6+ provides built-in convenience methods to find and decode the plain text body as in @Todor Minakov's answer. You can use the EMailMessage.get_body() and get_content() methods:

msg = email.message_from_string(s, policy=email.policy.default)
body = msg.get_body(('plain',))
if body:
    body = body.get_content()
print(body)

Note this will give None if there is no (obvious) plain text body part.

If you are reading from e.g. an mbox file, you can give the mailbox constructor an EmailMessage factory:

mbox = mailbox.mbox(mboxfile, factory=lambda f: email.message_from_binary_file(f, policy=email.policy.default), create=False)
for msg in mbox:
    ...

Note you must pass email.policy.default as the policy, since it's not the default...

The arrow operator is like dot, except it dereferences a pointer first. foo.bar() calls method bar() on object foo, foo->bar calls method bar on the object pointed to by pointer foo.

The problem may be that ssh is trying to connect to all the different IPs that www.google.com resolves to. For example on my machine:

# ssh -v -o ConnectTimeout=1 -o ConnectionAttempts=1 www.google.com
OpenSSH_5.9p1, OpenSSL 0.9.8t 18 Jan 2012
debug1: Connecting to www.google.com [173.194.43.20] port 22.

If I run it with a specific IP, it returns much faster.

EDIT: I've timed it (with time) and the results are:

• www.google.com - 5.086 seconds
• 173.94.43.16 - 1.054 seconds

You could use curl instead. It is installed by default into /usr/bin.

You cannot specify that it's always a file. If you don't need xcopy's other features, why not just use regular copy?
