Programs & Examples On #Ca1062

This post is very old and I find it very helpful so I decided to share the unset function I wrote in case someone else see this post and think why it's not so simple as it in PHP unset function.

The reason for writing this new unset function, is to keep the index of all other variables in this hash_map. Look at the following example, and see how the index of "test2" did not change after removing a value from the hash_map.

function unset(unsetKey, unsetArr, resort) {
  var tempArr = unsetArr;
  var unsetArr = {};
  delete tempArr[unsetKey];
  if (resort) {
    j = -1;
  }
  for (i in tempArr) {
    if (typeof(tempArr[i]) !== 'undefined') {
      if (resort) {
        j++;
      } else {
        j = i;
      }
      unsetArr[j] = tempArr[i];
    }
  }
  return unsetArr;
}

var unsetArr = ['test', 'deletedString', 'test2'];

console.log(unset('1', unsetArr, true)); // output Object {0: "test", 1: "test2"}
console.log(unset('1', unsetArr, false)); // output Object {0: "test", 2: "test2"}

You could use CSS to do that, but it wouldn't be supported in IE8-. You can use some site like http://borderradius.com to come up with actual CSS you'd use, which would look something like this (again, depending on how many browsers you're trying to support):

-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;

you can use toggleClass() to toggle class it is really handy.

case:1

<div id='mydiv' class="class1"></div>

$('#mydiv').toggleClass('class1 class2');

output: <div id='mydiv' class="class2"></div>

case:2

<div id='mydiv' class="class2"></div>

$('#mydiv').toggleClass('class1 class2');

output: <div id='mydiv' class="class1"></div>

case:3

<div id='mydiv' class="class1 class2 class3"></div>

$('#mydiv').toggleClass('class1 class2');

output: <div id='mydiv' class="class3"></div>

I got this error for a stupid mistake, the variable name in the @PathVariable wasn't matching the one in the @RequestMapping

For example

@RequestMapping(value = "/whatever/{**contentId**}", method = RequestMethod.POST)
public … method(@PathVariable Integer **contentID**){
}

It may help others

In my case the separator was not the default "," but Tab.

pd.read_csv(file_name.csv, sep='\\t',lineterminator='\\r', engine='python', header='infer')

Note: "\t" did not work as suggested by some sources. "\\t" was required.

You should not include folder node_modules in your .gitignore file (or rather you should include folder node_modules in your source deployed to Heroku).

If folder node_modules:

• exists then npm install will use those vendored libraries and will rebuild any binary dependencies with npm rebuild.
• doesn't exist then npm install will have to fetch all dependencies itself which adds time to the slug compile step.

See the Node.js buildpack source for these exact steps.

However, the original error looks to be an incompatibility between the versions of npm and Node.js. It is a good idea to always explicitly set the engines section of your packages.json file according to this guide to avoid these types of situations:

{
  "name": "myapp",
  "version": "0.0.1",
  "engines": {
    "node": "0.8.x",
    "npm":  "1.1.x"
  }
}

This will ensure development/production parity and reduce the likelihood of such situations in the future.

Try this

alter table TableName 
 add constraint df_ConstraintNAme 
 default getutcdate() for [Date]

example

create table bla (id int)

alter table bla add constraint dt_bla default 1 for id



insert bla default values

select * from bla

also make sure you name the default constraint..it will be a pain in the neck to drop it later because it will have one of those crazy system generated names...see also How To Name Default Constraints And How To Drop Default Constraint Without A Name In SQL Server

You can Try following function and its return your phoneModel name in string format.

public String phoneModel() {

    return Build.MODEL;
}

For the records, in OpenJPA before JPA2 it was @ElementDependant.

I believe that the correct answer would be to make the two numbers (BigDecimals), have the same scale, then we can decide about their equality. For example, are these two numbers equal?

1.00001 and 1.00002

Well, it depends on the scale. On the scale 5 (5 decimal points), no they are not the same. but on smaller decimal precisions (scale 4 and lower) they are considered equal. So I suggest make the scale of the two numbers equal and then compare them.

If your package.json looks something like the following:

  ...
  "devDependencies": {
    "babel": "^6.5.2",
    "babel-eslint": "^6.0.4",
    "babel-polyfill": "^6.8.0",
    "babel-preset-es2015": "^6.6.0",
    "babelify": "^7.3.0",
  ...

And you get the Cannot find module 'babel/polyfill' error message, then you probably just need to change your import statement FROM:

import "babel/polyfill";

TO:

import "babel-polyfill";

And make sure it comes before any other import statement (not necessarily at the entry point of your application).

Query the sysdepends table:

SELECT distinct schema_name(dependentObject.uid) as schema, 
       dependentObject.*
 FROM sysdepends d 
INNER JOIN sysobjects o on d.id = o.id 
INNER JOIN sysobjects dependentObject on d.depid = dependentObject.id
WHERE o.name = 'TableName'

A way to look just for views/functions/triggers/procedures that reference the object (or any given text) by name is:

SELECT distinct schema_name(so.uid) + '.' + so.name 
  FROM syscomments sc 
 INNER JOIN  sysobjects so on sc.id = so.id 
 WHERE sc.text like '%Name%'

    List<T> OriginalList = new List<T>();
    List<T> TempList = new List<T>();
    Random random = new Random();
    int length = OriginalList.Count;
    int TempIndex = 0;

    while (length > 0) {
        TempIndex = random.Next(0, length);  // get random value between 0 and original length
        TempList.Add(OriginalList[TempIndex]); // add to temp list
        OriginalList.RemoveAt(TempIndex); // remove from original list
        length = OriginalList.Count;  // get new list <T> length.
    }

    OriginalList = new List<T>();
    OriginalList = TempList; // copy all items from temp list to original list.

Here is the very simple example of CSV import using threading. (Library inclusion may differ for different purpose.)

Helper Functions:

from threading import Thread
from project import app
import csv


def import_handler(csv_file_name):
    thr = Thread(target=dump_async_csv_data, args=[csv_file_name])
    thr.start()

def dump_async_csv_data(csv_file_name):
    with app.app_context():
        with open(csv_file_name) as File:
            reader = csv.DictReader(File)
            for row in reader:
                # DB operation/query

Driver Function:

import_handler(csv_file_name)

Play 2.2.0 on Windows

Using a zip distribution (produced using the "dist" command), the only way I was able to change the startup port was by first setting JAVA_OPTS and then launching the application.

E.g., from the command line

set JAVA_OPTS=-Dhttp.port=9002
bin\myapp.bat

where myapp.bat is the batch file created by the "dist" command.

The following would always ignore my http.port parameter and attempt to start on the default port, 9000

bin\myapp.bat -Dhttp.port=9002

However, I've noticed that this works fine on Linux/OSX, starting up on the requested port:

./bin/myapp -Dhttp.port=9002

A simple way is set android:usesCleartextTraffic="true" on you AndroidManifest.xml

android:usesCleartextTraffic="true"

Your AndroidManifest.xml look like

<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.dww.drmanar">
   <application
       android:icon="@mipmap/ic_launcher"
       android:label="@string/app_name"
       android:usesCleartextTraffic="true"
       android:theme="@style/AppTheme"
       tools:targetApi="m">
       <activity
            android:name=".activity.SplashActivity"
            android:theme="@style/FullscreenTheme">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
       </activity>
    </application>
</manifest>

I hope this will help you.

TLDR: You can first filter your array and then perform your map but this would require two passes on the array (filter returns an array to map). Since this array is small, it is a very small performance cost. You can also do a simple reduce. However if you want to re-imagine how this can be done with a single pass over the array (or any datatype), you can use an idea called "transducers" made popular by Rich Hickey.

Answer:

We should not require increasing dot chaining and operating on the array [].map(fn1).filter(f2)... since this approach creates intermediate arrays in memory on every reducing function.

The best approach operates on the actual reducing function so there is only one pass of data and no extra arrays.

The reducing function is the function passed into reduce and takes an accumulator and input from the source and returns something that looks like the accumulator

// 1. create a concat reducing function that can be passed into `reduce`
const concat = (acc, input) => acc.concat([input])

// note that [1,2,3].reduce(concat, []) would return [1,2,3]

// transforming your reducing function by mapping
// 2. create a generic mapping function that can take a reducing function and return another reducing function
const mapping = (changeInput) => (reducing) => (acc, input) => reducing(acc, changeInput(input))

// 3. create your map function that operates on an input
const getSrc = (x) => x.src
const mappingSrc = mapping(getSrc)

// 4. now we can use our `mapSrc` function to transform our original function `concat` to get another reducing function
const inputSources = [{src:'one.html'}, {src:'two.txt'}, {src:'three.json'}]
inputSources.reduce(mappingSrc(concat), [])
// -> ['one.html', 'two.txt', 'three.json']

// remember this is really essentially just
// inputSources.reduce((acc, x) => acc.concat([x.src]), [])


// transforming your reducing function by filtering
// 5. create a generic filtering function that can take a reducing function and return another reducing function
const filtering = (predicate) => (reducing) => (acc, input) => (predicate(input) ? reducing(acc, input): acc)

// 6. create your filter function that operate on an input
const filterJsonAndLoad = (img) => {
  console.log(img)
  if(img.src.split('.').pop() === 'json') {
    // game.loadSprite(...);
    return false;
  } else {
    return true;
  }
}
const filteringJson = filtering(filterJsonAndLoad)

// 7. notice the type of input and output of these functions
// concat is a reducing function,
// mapSrc transforms and returns a reducing function
// filterJsonAndLoad transforms and returns a reducing function
// these functions that transform reducing functions are "transducers", termed by Rich Hickey
// source: http://clojure.com/blog/2012/05/15/anatomy-of-reducer.html
// we can pass this all into reduce! and without any intermediate arrays

const sources = inputSources.reduce(filteringJson(mappingSrc(concat)), []);
// [ 'one.html', 'two.txt' ]

// ==================================
// 8. BONUS: compose all the functions
// You can decide to create a composing function which takes an infinite number of transducers to
// operate on your reducing function to compose a computed accumulator without ever creating that
// intermediate array
const composeAll = (...args) => (x) => {
  const fns = args
  var i = fns.length
  while (i--) {
    x = fns[i].call(this, x);
  }
  return x
}

const doABunchOfStuff = composeAll(
    filtering((x) => x.src.split('.').pop() !== 'json'),
    mapping((x) => x.src),
    mapping((x) => x.toUpperCase()),
    mapping((x) => x + '!!!')
)

const sources2 = inputSources.reduce(doABunchOfStuff(concat), [])
// ['ONE.HTML!!!', 'TWO.TXT!!!']

If you are using Google fonts I would suggest the following.

If you want the fonts to run from your localhost or server you need to download the files.

Instead of downloading the ttf packages in the download links, use the live link they provide, for example:

http://fonts.googleapis.com/css?family=Source+Sans+Pro:300,400,600,300italic,400italic,600italic

Paste the URL in your browser and you should get a font-face declaration similar to the first answer.

Open the URLs provided, download and rename the files.

Stick the updated font-face declarations with relative paths to the woff files in your CSS, and you are done.

You can update a metadata annotation that is not relevant for your deployment. it will trigger a rolling-update

for example:

    spec:
      template:
        metadata:
          annotations:
            configmap-version: 1

Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

I think you just have it backwards.

print ", ".join(set_3)

You could run your JUnit test from a main method and repeat it so many times you need:

package tests;

import static org.junit.Assert.*;

import org.junit.Test;
import org.junit.runner.Result;

public class RepeatedTest {

    @Test
    public void test() {
        fail("Not yet implemented");
    }

    public static void main(String args[]) {

        boolean runForever = true;

        while (runForever) {
            Result result = org.junit.runner.JUnitCore.runClasses(RepeatedTest.class);

            if (result.getFailureCount() > 0) {
                runForever = false;
               //Do something with the result object

            }
        }

    }

}

From Oracle Wiki, error 02287 is

An ORA-02287 occurs when you use a sequence where it is not allowed.

Of the places where sequences can't be used, you seem to be trying:

In a sub-query

So it seems you can't do multiples in the same statement.

The solution they offer is:

If you want the sequence value to be inserted into the column for every row created, then create a before insert trigger and fetch the sequence value in the trigger and assign it to the column

I would suggest not to use seaborn pointplot for plotting. This makes things unnecessarily complicated.
Instead use matplotlib plot_date. This allows to set labels to the plots and have them automatically put into a legend with ax.legend().

import matplotlib.pyplot as plt
import pandas as pd
import seaborn as sns
import numpy as np

date = pd.date_range("2017-03", freq="M", periods=15)
count = np.random.rand(15,4)
df1 = pd.DataFrame({"date":date, "count" : count[:,0]})
df2 = pd.DataFrame({"date":date, "count" : count[:,1]+0.7})
df3 = pd.DataFrame({"date":date, "count" : count[:,2]+2})

f, ax = plt.subplots(1, 1)
x_col='date'
y_col = 'count'

ax.plot_date(df1.date, df1["count"], color="blue", label="A", linestyle="-")
ax.plot_date(df2.date, df2["count"], color="red", label="B", linestyle="-")
ax.plot_date(df3.date, df3["count"], color="green", label="C", linestyle="-")

ax.legend()

plt.gcf().autofmt_xdate()
plt.show()

sns.pointplot(ax=ax,x=x_col,y=y_col,data=df1,color='blue')
sns.pointplot(ax=ax,x=x_col,y=y_col,data=df2,color='green')
sns.pointplot(ax=ax,x=x_col,y=y_col,data=df3,color='red')

ax.legend(handles=ax.lines[::len(df1)+1], labels=["A","B","C"])

ax.set_xticklabels([t.get_text().split("T")[0] for t in ax.get_xticklabels()])
plt.gcf().autofmt_xdate()

plt.show()

Two points:

1. If you are running a 32 bit Windows, you won't have all the 4GB accessible, only 2GB.
2. Don't forget that the underlying implementation of List is an array. If your memory is heavily fragmented, there may not be enough contiguous space to allocate your List, even though in total you have plenty of free memory.

It means assign the key to $user and the variable to $pass

When you assign an array, you do it like this

$array = array("key" => "value");

It uses the same symbol for processing arrays in foreach statements. The '=>' links the key and the value.

According to the PHP Manual, the '=>' created key/value pairs.

Also, Equal or Greater than is the opposite way: '>='. In PHP the greater or less than sign always goes first: '>=', '<='.

And just as a side note, excluding the second value does not work like you think it would. Instead of only giving you the key, It actually only gives you a value:

$array = array("test" => "foo");

foreach($array as $key => $value)
{
    echo $key . " : " . $value; // Echoes "test : foo"
}

foreach($array as $value)
{
    echo $value; // Echoes "foo"
}

In newer versions(>=1.8.0) of docker, you can do this

docker build -f Dockerfile.db .
docker build -f Dockerfile.web .

A big save.

EDIT: update versions per raksja's comment

EDIT: comment from @vsevolod: it's possible to get syntax highlighting in VS code by giving files .Dockerfile extension(instead of name) e.g. Prod.Dockerfile, Test.Dockerfile etc.

I think the complication may also occur when trying to nest multiple Divs within the return statement. You may wish to do this to ensure your components render as block elements.

Here's an example of correctly rendering a couple of components, using multiple divs.

return (
  <div>
    <h1>Data Information</H1>
    <div>
      <Button type="primary">Create Data</Button>
    </div>
  </div>
)

Install PIL(Python Image Library) :

then:

from PIL import Image
myImage = Image.open("your_image_here");
myImage.show();

For some reason none of the answers worked for me so I had to override the restoreState method without calling super in my fragmentStatePagerAdapter. Code:

private class MyAdapter extends FragmentStatePagerAdapter {

    // [Rest of implementation]

    @Override
    public void restoreState(Parcelable state, ClassLoader loader) {}

}

If you set the margin to be margin:0 auto the image will be centered.

This will give top + bottom a margin of 0, and left and right a margin of 'auto'. Since the div has a width (200px), the image will be 200px wide and the browser will auto set the left and right margin to half of what is left on the page, which will result in the image being centered.

Try this...  
  <script type="text/javascript">

    $(document).ready(function(){

    $("#find").click(function(){
        var username  = $("#username").val();
            $.ajax({
            type: 'POST',
            dataType: 'json',
            url: 'includes/find.php',
            data: 'username='+username,
            success: function( data ) {
            //in data you result will be available...
            response = jQuery.parseJSON(data);
//further code..
            },

    error: function(xhr, status, error) {
        alert(status);
        },
    dataType: 'text'

    });
        });

    });



    </script>

    <form name="Find User" id="userform" class="invoform" method="post" />

    <div id ="userdiv">
      <p>Name (Lastname, firstname):</p>
      </label>
      <input type="text" name="username" id="username" class="inputfield" />
      <input type="button" name="find" id="find" class="passwordsubmit" value="find" />
    </div>
    </form>
    <div id="userinfo"><b>info will be listed here.</b></div>

USING PHP, HTML AND JAVASCRIPT for prompting

Just if someone looking for using php, html and javascript in a single file, the answer below is working for me.. i attached with the used of bootstrap icon "trash" for the link.

<a class="btn btn-danger" href="<?php echo "delete.php?&var=$var"; ?>" onclick="return confirm('Are you sure want to delete this?');"><span class="glyphicon glyphicon-trash"></span></a>

the reason i used php code in the middle is because i cant use it from the beginning..

the code below doesnt work for me:-

echo "<a class='btn btn-danger' href='delete.php?&var=$var' onclick='return confirm('Are you sure want to delete this?');'><span class='glyphicon glyphicon-trash'></span></a>";

and i modified it as in the 1st code then i run as just what i need.. I hope that can i can help someone inneed of my case.

OK, there are lots of solutions here but non actually explain the root cause of the problem so here we go:

when you see an attribute like android:layout_width="match_parent" the android part is the prefix, the format for an attribute here is PREFIX:NAME="VALUE". in XML, namespaces and prefixes are ways to avoid naming conflicts for example we can have two distinct attributes with same name but different prefixes like: a:a="val" and b:a="val".

to use prefixes like android or app or any other your should define a namespace using xmlns attribute.

so if you have this issue just find prefixes that do not have a namespace defined, if you have tools:... you should add tools namespace as some answeres suggested, if you have app:... attribute you should add xmlns:app="http://schemas.android.com/apk/res-auto" to the root element

XML Namespaces simple explanation

XML Namespaces in W3

As mentioned in the comments height:100% relies on the height of the parent container being explicitly defined. One way to achieve what you want is to use absolute/relative positioning, and specifying the left/right/top/bottom properties to "stretch" the content out to fill the available space. I have implemented what I gather you want to achieve in jsfiddle. Try resizing the Result window and you will see the content resizes automatically.

The limitation of this approach in your case is that you have to specify an explicit margin-top on the parent container to offset its contents down to make room for the header content. You can make it dynamic if you throw in javascript though.

Follow the following steps if you are using proxy server:

1. Open Eclipse
2. Window >> Android SDK Manager >> Option
3. Input your proxy server and port.

Hope this helps.

jQuery does only make some regexp checking before calling the native browser method window.JSON.parse(). If that is not available, it uses eval() or more exactly new Function() to create a Javascript object.

The opposite of JSON.parse() is JSON.stringify() which serializes a Javascript object into a string. jQuery does not have functionality of its own for that, you have to use the browser built-in version or json2.js from http://www.json.org

JSON.stringify() is available in all major browsers, but to be compatible with older browsers you still need that fallback.

On a recent project built using Bootstrap 4, I had tried all of the above methods but nothing worked. My approach was by editing the library CSS using jQuery to get 100% on the table.

 // * Select2 4.0.7

$('.select2-multiple').select2({
    // theme: 'bootstrap4', //Doesn't work
    // width:'100%', //Doesn't work
    width: 'resolve'
});

//The Fix
$('.select2-w-100').parent().find('span')
    .removeClass('select2-container')
    .css("width", "100%")
    .css("flex-grow", "1")
    .css("box-sizing", "border-box")
    .css("display", "inline-block")
    .css("margin", "0")
    .css("position", "relative")
    .css("vertical-align", "middle")

You can create dynamically like the below code:

JSONObject jsonBody = new JSONObject();
try {
    jsonBody.put("username", userName);
    jsonBody.put("email", email);
    jsonBody.put("phone", contactNumber);
    jsonBody.put("password", password);
    jsonBody.put("carType", carType);
    jsonBody.put("fcmToken", "lljlkdsajfljasldfj;lsa");
    jsonBody.put("profilePhoto", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg");

    JSONObject document = new JSONObject();

    try {
        document.put("DL", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
        document.put("Registration", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
        document.put("Insurance", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
        document.put("CarInside", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
        document.put("CarOutside", createDocument("5fccb687c5b4260011810125", "https://st.depositphotos.com/2101611/3925/v/600/depositphotos_39258143-stock-illustration-businessman-avatar-profile-picture.jpg"));
    } catch (JSONException e) {
        e.printStackTrace();
    }

    jsonBody.put("documents", document.toString());

    Log.i("MAHDI", "Hello: Mahdi: Data: " + jsonBody);
} catch (JSONException e) {
    e.printStackTrace();
}

And the createDocument method code:

public JSONArray createDocument(String id, String imageUrl) {

JSONObject dlObject = new JSONObject();
try {
    dlObject.put("_id", id);
    dlObject.put("uriPath", imageUrl);
} catch (JSONException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
JSONArray dlArray = new JSONArray();
dlArray.put(dlObject);

return dlArray;
}

window.onload = function() {
    var el = document.documentElement,
        rfs = el.requestFullScreen
        || el.webkitRequestFullScreen
        || el.mozRequestFullScreen;
    rfs.call(el);
};

I had the same problem. The offset appeared after UpdatePanel refresh. The solution was to add an empty tag before the UpdatePanel like this:

<div></div>

...

The reason why your code doesn't work is because $watch by default does reference check. So in a nutshell it make sure that the object which is passed to it is new object. But in your case you are just modifying some property of form object not creating a new one. In order to make it work you can pass true as the third parameter.

$scope.$watch('form', function(newVal, oldVal){
    console.log('invoked');
}, true);

It will work but You can use $watchCollection which will be more efficient then $watch because $watchCollection will watch for shallow properties on form object. E.g.

$scope.$watchCollection('form', function (newVal, oldVal) {
    console.log(newVal, oldVal);
});

How to rotate an image around its center:

ImageView view = ... //Initialize ImageView via FindViewById or programatically

RotateAnimation anim = new RotateAnimation(0.0f, 360.0f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);

//Setup anim with desired properties
anim.setInterpolator(new LinearInterpolator());
anim.setRepeatCount(Animation.INFINITE); //Repeat animation indefinitely
anim.setDuration(700); //Put desired duration per anim cycle here, in milliseconds

//Start animation
view.startAnimation(anim); 
//Later on, use view.setAnimation(null) to stop it.

This will cause the image to rotate around its center (0.5 or 50% of its width/height). I am posting this for future readers who get here from Google, as I have, and who wish to rotate the image around its center without defining said center in absolute pixels.

When you create the emulator, you need to choose properties CPU/ABI is Intel Atom (installed it in SDK manager )

That's not true Jeff.

You simply have to select a folder within your IIS 7 Manager UI (e.g. Images or event the Default Web Application folder) and then click on "HTTP Response Headers". Then you have to click on "Set Common Header.." in the right pane and select the "Expire Web content". There you can easily configure a max-age of 24 hours by choosing "After:", entering "24" in the Textbox and choose "Hours" in the combobox.

Your first paragraph regarding the web.config entry is right. I'd add the cacheControlCustom-attribute to set the cache control header to "public" or whatever is needed in that case.

You can, of course, achieve the same by providing web.config entries (or files) as needed.

Edit: removed a confusing sentence :)

SELECT
        a.attname as "Column",
        pg_catalog.format_type(a.atttypid, a.atttypmod) as "Datatype"
    FROM
        pg_catalog.pg_attribute a
    WHERE
        a.attnum > 0
        AND NOT a.attisdropped
        AND a.attrelid = (
            SELECT c.oid
            FROM pg_catalog.pg_class c
                LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
            WHERE c.relname ~ '^(hello world)$'
                AND pg_catalog.pg_table_is_visible(c.oid)
        );

More info on it : http://www.postgresql.org/docs/9.3/static/catalog-pg-attribute.html

You can wrap it in your own function:

function isNullAndUndef(variable) {

    return (variable !== null && variable !== undefined);
}

Let me recommend you using Selenide library. It allows writing much more concise and readable tests. It can wait for presence of elements with much shorter syntax:

$("#elementId").shouldBe(visible);

Here is a sample project for testing Google search: https://github.com/selenide-examples/google

The way i do it is:

   var obj = new Object();
   obj.name = "Raj";
   obj.age  = 32;
   obj.married = false;
   var jsonString= JSON.stringify(obj);

I guess this way can reduce chances for errors.

1. Java is slow, most of the heavy lifting is not handled by the GPU. There's still animation, physics, and AI hitting the CPU, all of which are very time-consuming.

2. Java doesn't exist on consoles, and consoles are a major target for commercial games. If you use Java on PC, you're eliminating your ability to port to consoles within reasonable time and budget.

3. Many of the more experienced coders in the game industry have been using C and C++ long before Java became popular. The two points above may contribute to this, but I expect that many professional game coders just don't really know Java all that well.

4. Someone else's point about middleware above was a good one, so I'm adding it to my answer. There's a lot of legacy code and middleware written specifically to link with C/C++, and last I checked Java doesn't have good interoperability. Using Java for most companies would involve throwing out a lot of code, much of which has been paid for in one way or another.

    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    DocumentBuilder db = dbf.newDocumentBuilder();
    Document dom = db.parse("file.xml");
    Element docEle = dom.getDocumentElement();
    NodeList nl = docEle.getChildNodes();
    int length = nl.getLength();
    for (int i = 0; i < length; i++) {
        if (nl.item(i).getNodeType() == Node.ELEMENT_NODE) {
            Element el = (Element) nl.item(i);
            if (el.getNodeName().contains("staff")) {
                String name = el.getElementsByTagName("name").item(0).getTextContent();
                String phone = el.getElementsByTagName("phone").item(0).getTextContent();
                String email = el.getElementsByTagName("email").item(0).getTextContent();
                String area = el.getElementsByTagName("area").item(0).getTextContent();
                String city = el.getElementsByTagName("city").item(0).getTextContent();
            }
        }
    }

Iterate over all children and nl.item(i).getNodeType() == Node.ELEMENT_NODE is used to filter text nodes out. If there is nothing else in XML what remains are staff nodes.

For each node under stuff (name, phone, email, area, city)

 el.getElementsByTagName("name").item(0).getTextContent(); 

el.getElementsByTagName("name") will extract the "name" nodes under stuff, .item(0) will get you the first node and .getTextContent() will get the text content inside.

Edit: Since we have jackson I would do this in a different way. Define a pojo for the object:

public class Staff {
    private String name;
    private String phone;
    private String email;
    private String area;
    private String city;
...getters setters
}

Then using jackson:

    JsonNode root = new XmlMapper().readTree(xml.getBytes());
    ObjectMapper mapper = new ObjectMapper();
    root.forEach(node -> consume(node, mapper));



private void consume(JsonNode node, ObjectMapper mapper) {
    try {
        Staff staff = mapper.treeToValue(node, Staff.class);
        //TODO your job with staff
    } catch (JsonProcessingException e) {
        e.printStackTrace();
    }
}

The catch is that input elements are inline. We have to make it block (display:block) before positioning it to center : margin : 0 auto. Please see the code below :

<html>
<head>
    <style>
        div.wrapper {
            width: 300px;
            height:300px;
            border:1px solid black;
        }

        input[type="text"] {
             display: block;
             margin : 0 auto;
        }

    </style>
</head>
<body>

    <div class='wrapper'>
        <input type='text' name='ok' value='ok'>
    </div>    


</body>
</html>

But if you have a div which is positioned = absolute then we need to do the things little bit differently.Now see this!

  <html>
     <head>
    <style>
        div.wrapper {
            position:  absolute;
            top : 200px;
            left: 300px;
            width: 300px;
            height:300px;
            border:1px solid black;
        }

        input[type="text"] {
             position: relative;
             display: block;
             margin : 0 auto;
        }

    </style>
</head>
<body>

    <div class='wrapper'>
        <input type='text' name='ok' value='ok'>
    </div>  

</body>
</html>

Hoping this can be helpful.Thank you.

Watch this video, I had the same question. He shows you how to debug the service as well.

Here are his instructions using the basic C# Windows Service template in Visual Studio 2010/2012.

You add this to the Service1.cs file:

public void onDebug()
{
    OnStart(null);
}

You change your Main() to call your service this way if you are in the DEBUG Active Solution Configuration.

static void Main()
{
    #if DEBUG
    //While debugging this section is used.
    Service1 myService = new Service1();
    myService.onDebug();
    System.Threading.Thread.Sleep(System.Threading.Timeout.Infinite);

    #else
    //In Release this section is used. This is the "normal" way.
    ServiceBase[] ServicesToRun;
    ServicesToRun = new ServiceBase[] 
    { 
        new Service1() 
    };
    ServiceBase.Run(ServicesToRun);
    #endif
}

Keep in mind that while this is an awesome way to debug your service. It doesn't call OnStop() unless you explicitly call it similar to the way we called OnStart(null) in the onDebug() function.

Using the angular.module API with an array at the end will tell angular to create a new module:

myApp.js

// It is like saying "create a new module"
angular.module('myApp.controllers', []); // Notice the empty array at the end here

Using it without the array is actually a getter function. So to seperate your controllers, you can do:

Ctrl1.js

// It is just like saying "get this module and create a controller"
angular.module('myApp.controllers').controller('Ctrlr1', ['$scope', '$http', function($scope, $http) {}]);

Ctrl2.js

angular.module('myApp.controllers').controller('Ctrlr2', ['$scope', '$http', function($scope, $http) {}]);

During your javascript imports, just make sure myApp.js is after AngularJS but before any controllers / services / etc...otherwise angular won't be able to initialize your controllers.

In the Google docs, they've identified a pagespeed filter that will load the script asynchronously:

ModPagespeedEnableFilters make_google_analytics_async

You can find the documentation here: https://developers.google.com/speed/pagespeed/module/filter-make-google-analytics-async

One thing to highlight is that the filter is considered high risk. From the docs:

The make_google_analytics_async filter is experimental and has not had extensive real-world testing. One case where a rewrite would cause errors is if the filter misses calls to Google Analytics methods that return values. If such methods are found, the rewrite is skipped. However, the disqualifying methods will be missed if they come before the load, are in attributes such as "onclick", or if they are in external resources. Those cases are expected to be rare.

You'll want to use JavaScript's Array splice method:

var tag_story = [1,3,56,6,8,90],
    id_tag = 90,
    position = tag_story.indexOf(id_tag);

if ( ~position ) tag_story.splice(position, 1);

P.S. For an explanation of that cool ~ tilde shortcut, see this post:

Using a ~ tilde with indexOf to check for the existence of an item in an array.

Note: IE < 9 does not support .indexOf() on arrays. If you want to make sure your code works in IE, you should use jQuery's $.inArray():

var tag_story = [1,3,56,6,8,90],
    id_tag = 90,
    position = $.inArray(id_tag, tag_story);

if ( ~position ) tag_story.splice(position, 1);

If you want to support IE < 9 but don't already have jQuery on the page, there's no need to use it just for $.inArray. You can use this polyfill instead.

If you could use something other than 'awk' , then try this instead

echo '1540 "A B"' | cut -d' ' -f2-

-d is a delimiter, -f is the field to cut and with -f2- we intend to cut the 2nd field until end.

I wrote an extension that takes into account all possible cases:

• If access is allowed, then the code onAccessHasBeenGranted will be run.
• If access is not determined, then requestAuthorization(_:) will be called.
• If the user has denied your app photo library access, then the user will be shown a window offering to go to settings and allow access. In this window, the "Cancel" and "Settings" buttons will be available to him. When he presses the "settings" button, your application settings will open.

Usage example:

PHPhotoLibrary.execute(controller: self, onAccessHasBeenGranted: {
    // access granted... 
})

Extension code:

import Photos
import UIKit

public extension PHPhotoLibrary {

   static func execute(controller: UIViewController,
                       onAccessHasBeenGranted: @escaping () -> Void,
                       onAccessHasBeenDenied: (() -> Void)? = nil) {

      let onDeniedOrRestricted = onAccessHasBeenDenied ?? {
         let alert = UIAlertController(
            title: "We were unable to load your album groups. Sorry!",
            message: "You can enable access in Privacy Settings",
            preferredStyle: .alert)
         alert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: nil))
         alert.addAction(UIAlertAction(title: "Settings", style: .default, handler: { _ in
            if let settingsURL = URL(string: UIApplication.openSettingsURLString) {
               UIApplication.shared.open(settingsURL)
            }
         }))
         controller.present(alert, animated: true)
      }

      let status = PHPhotoLibrary.authorizationStatus()
      switch status {
      case .notDetermined:
         onNotDetermined(onDeniedOrRestricted, onAccessHasBeenGranted)
      case .denied, .restricted:
         onDeniedOrRestricted()
      case .authorized:
         onAccessHasBeenGranted()
      @unknown default:
         fatalError("PHPhotoLibrary::execute - \"Unknown case\"")
      }
   }

}

private func onNotDetermined(_ onDeniedOrRestricted: @escaping (()->Void), _ onAuthorized: @escaping (()->Void)) {
   PHPhotoLibrary.requestAuthorization({ status in
      switch status {
      case .notDetermined:
         onNotDetermined(onDeniedOrRestricted, onAuthorized)
      case .denied, .restricted:
         onDeniedOrRestricted()
      case .authorized:
         onAuthorized()
      @unknown default:
         fatalError("PHPhotoLibrary::execute - \"Unknown case\"")
      }
   })
}

Your student.h file only forward declares a struct named "Student", it does not define one. This is sufficient if you only refer to it through reference or pointer. However, as soon as you try to use it (including creating one) you will need the full definition of the structure.

In short, move your struct Student { ... }; into the .h file and use the .cpp file for implementation of member functions (which it has none so you don't need a .cpp file).

Two options:

for (let item in MotifIntervention) {
    if (isNaN(Number(item))) {
        console.log(item);
    }
}

Or

Object.keys(MotifIntervention).filter(key => !isNaN(Number(MotifIntervention[key])));

(code in playground)

Edit

String enums look different than regular ones, for example:

enum MyEnum {
    A = "a",
    B = "b",
    C = "c"
}

Compiles into:

var MyEnum;
(function (MyEnum) {
    MyEnum["A"] = "a";
    MyEnum["B"] = "b";
    MyEnum["C"] = "c";
})(MyEnum || (MyEnum = {}));

Which just gives you this object:

{
    A: "a",
    B: "b",
    C: "c"
}

You can get all the keys (["A", "B", "C"]) like this:

Object.keys(MyEnum);

And the values (["a", "b", "c"]):

Object.keys(MyEnum).map(key => MyEnum[key])

Or using Object.values():

Object.values(MyEnum)

>>> l = [['40', '20', '10', '30'], ['20', '20', '20', '20', '20', '30', '20'], ['30', '20', '30', '50', '10', '30', '20', '20', '20'], ['100', '100'], ['100', '100', '100', '100', '100'], ['100', '100', '100', '100']]
>>> new_list = [float(x) for xs in l for x in xs]
>>> new_list
[40.0, 20.0, 10.0, 30.0, 20.0, 20.0, 20.0, 20.0, 20.0, 30.0, 20.0, 30.0, 20.0, 30.0, 50.0, 10.0, 30.0, 20.0, 20.0, 20.0, 100.0, 100.0, 100.0, 100.0, 100.0, 100.0, 100.0, 100.0, 100.0, 100.0, 100.0]

I answered something like this in another question already, but will change it just a little for this one.

Unfortunately, there is no getImageResource() or getDrawableId(). But, I created a simple workaround by using the ImageView tags.

In onCreate():

imageView0 = (ImageView) findViewById(R.id.imageView0);
imageView1 = (ImageView) findViewById(R.id.imageView1);
imageView2 = (ImageView) findViewById(R.id.imageView2);

imageView0.setTag(R.drawable.apple);
imageView1.setTag(R.drawable.banana);
imageView2.setTag(R.drawable.cereal);

Then, if you like, you can create a simple function to get the drawable id:

private int getDrawableId(ImageView iv) {
    return (Integer) iv.getTag();
}

Too easy.

Regarding the PHP comment 'No, PHP wouldn't like it'. Actually, PHP would keep on chugging unless you set some very restrictive (for PHP) exception/error levels, (and maybe not even then).

What WILL happen by default is that an access to a non existing variable/out of bounds array element 'unsets' your value that you're assigning to. NO, that is NOT null. PHP has a Perl/C lineage, from what I understand. So there are: unset and non existing variables, values which ARE set but are NULL, Boolean False values, then everything else that standard langauges have. You have to test for those separately, OR choose the RIGHT evaluation built in function/syntax.

ng-change requires ng-model,

<input type="text" name="abc" class="color" ng-model="someName" ng-change="myStyle={color:'green'}">

You don't need to use a regular expression for this.

var video_id = window.location.search.split('v=')[1];
var ampersandPosition = video_id.indexOf('&');
if(ampersandPosition != -1) {
  video_id = video_id.substring(0, ampersandPosition);
}

To return a value from a VBScript function, assign the value to the name of the function, like this:

Function getNumber
    getNumber = "423"
End Function

As @Cephalopod stated it isn't possible but you can shorten a UUID to 22 characters

public static String encodeUUIDBase64(UUID uuid) {
        ByteBuffer bb = ByteBuffer.wrap(new byte[16]);
        bb.putLong(uuid.getMostSignificantBits());
        bb.putLong(uuid.getLeastSignificantBits());
        return StringUtils.trimTrailingCharacter(BaseEncoding.base64Url().encode(bb.array()), '=');
}

Since Java 7 you can do the same with Files.newBufferedWriter a little more succinctly:

Path logFile = Paths.get("/tmp/example.txt");
try (BufferedWriter writer = Files.newBufferedWriter(logFile, StandardCharsets.UTF_8)) {
    writer.write("Hello World!");
    // ...
}

Try just --with-curl, without specifying a location, and see if it'll find it by itself.

Since you are not worried about IE, why not just use css transitions to provide the animation and jQuery to change the classes. Live example: http://jsfiddle.net/tw16/JfK6N/

#someDiv{
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}

This may be because @GlennMaynard is looking at the matter as in comparison with other languages, but in Python, you do things the python way. It's not a 'why' question. It's there and you can do things to the same effect with x+=. In The Zen of Python, it is given: "there should only be one way to solve a problem." Multiple choices are great in art (freedom of expression) but lousy in engineering.

Do you mean design as in 'graphic representation of tables' or just plain old 'engineering kind of design'. If it's the latter, use FlameRobin, version 0.9.0 has just been released.

If it's the former, then use DBDesigner. Yup, that uses Java.

Or maybe you meant something more like MS Access. Then Kexi should be right for you.

Try:

if($("option[value='parcel']").is(":checked"))
   $('#row_dim').show();

Or even:

$(function() {
    $('#type').change(function(){
        $('#row_dim')[ ($("option[value='parcel']").is(":checked"))? "show" : "hide" ]();  
    });
});

Shorter, more reliable and more performant than the current best-voted answer:

const getCookieValue = (name) => (
  document.cookie.match('(^|;)\\s*' + name + '\\s*=\\s*([^;]+)')?.pop() || ''
)

A performance comparison of various approaches is shown here:

http://jsperf.com/get-cookie-value-regex-vs-array-functions

Some notes on approach:

The regex approach is not only the fastest in most browsers, it yields the shortest function as well. Additionally it should be pointed out that according to the official spec (RFC 2109), the space after the semicolon which separates cookies in the document.cookie is optional and an argument could be made that it should not be relied upon. Additionally, whitespace is allowed before and after the equals sign (=) and an argument could be made that this potential whitespace should be factored into any reliable document.cookie parser. The regex above accounts for both of the above whitespace conditions.

While my original answer below is still valid and might be helpful to understand the cause for DNS based URL forwarding not being available via Amazon Route 53 out of the box, I highly recommend checking out Vivek M. Chawla's utterly smart indirect solution via the meanwhile introduced Amazon S3 Support for Website Redirects and achieving a self contained server less and thus free solution within AWS only like so.

• Implementing an automated solution to generate such redirects is left as an exercise for the reader, but please pay tribute to Vivek's epic answer by publishing your solution ;)

Original Answer

Nettica must be running a custom redirection solution for this, here is the problem:

You could create a CNAME alias like aws.example.com for myaccount.signin.aws.amazon.com, however, DNS provides no official support for aliasing a subdirectory like console in this example.

• It's a pity that AWS doesn't appear to simply do this by default when hitting https://myaccount.signin.aws.amazon.com/ (I just tried), because it would solve you problem right away and make a lot of sense in the first place; besides, it should be pretty easy to configure on their end.

For that reason a few DNS providers have apparently implemented a custom solution to allow redirects to subdirectories; I venture the guess that they are basically facilitating a CNAME alias for a domain of their own and are redirecting again from there to the final destination via an immediate HTTP 3xx Redirection.

So to achieve the same result, you'd need to have a HTTP service running performing these redirects, which is not the simple solution one would hope for of course. Maybe/Hopefully someone can come up with a smarter approach still though.

We had the same problem and managed to solve it by using a PhoneStateListener to identify when the call ends, but additionally we had to finish() the original activity before starting it again with startActivity, otherwise the call log would be in front of it.

Adding an answer because none of the existing answers specifically address the confusion in the official literature.

Generator functions are ordinary functions defined using yield instead of return. When called, a generator function returns a generator object, which is a kind of iterator - it has a next() method. When you call next(), the next value yielded by the generator function is returned.

Either the function or the object may be called the "generator" depending on which Python source document you read. The Python glossary says generator functions, while the Python wiki implies generator objects. The Python tutorial remarkably manages to imply both usages in the space of three sentences:

Generators are a simple and powerful tool for creating iterators. They are written like regular functions but use the yield statement whenever they want to return data. Each time next() is called on it, the generator resumes where it left off (it remembers all the data values and which statement was last executed).

The first two sentences identify generators with generator functions, while the third sentence identifies them with generator objects.

Despite all this confusion, one can seek out the Python language reference for the clear and final word:

The yield expression is only used when defining a generator function, and can only be used in the body of a function definition. Using a yield expression in a function definition is sufficient to cause that definition to create a generator function instead of a normal function.

When a generator function is called, it returns an iterator known as a generator. That generator then controls the execution of a generator function.

So, in formal and precise usage, "generator" unqualified means generator object, not generator function.

The above references are for Python 2 but Python 3 language reference says the same thing. However, the Python 3 glossary states that

generator ... Usually refers to a generator function, but may refer to a generator iterator in some contexts. In cases where the intended meaning isn’t clear, using the full terms avoids ambiguity.

If one wants to support Generics (in an extension method) this is the pattern...

public  static List<T> Deserialize<T>(this string SerializedJSONString)
{
    var stuff = JsonConvert.DeserializeObject<List<T>>(SerializedJSONString);
    return stuff;
}

It is used like this:

var rc = new MyHttpClient(URL);
//This response is the JSON Array (see posts above)
var response = rc.SendRequest();
var data = response.Deserialize<MyClassType>();

MyClassType looks like this (must match name value pairs of JSON array)

[JsonObject(MemberSerialization = MemberSerialization.OptIn)]
 public class MyClassType
 {
    [JsonProperty(PropertyName = "Id")]
    public string Id { get; set; }

    [JsonProperty(PropertyName = "Name")]
    public string Name { get; set; }

    [JsonProperty(PropertyName = "Description")]
    public string Description { get; set; }

    [JsonProperty(PropertyName = "Manager")]
    public string Manager { get; set; }

    [JsonProperty(PropertyName = "LastUpdate")]
    public DateTime LastUpdate { get; set; }
 }

If you want to interpret $replace, you should not use single quotes since they prevent variable substitution.

Try:

echo $LINE | sed -e "s/12345678/${replace}/g"

Transcript:

pax> export replace=987654321
pax> echo X123456789X | sed "s/123456789/${replace}/"
X987654321X
pax> _

Just be careful to ensure that ${replace} doesn't have any characters of significance to sed (like / for instance) since it will cause confusion unless escaped. But if, as you say, you're replacing one number with another, that shouldn't be a problem.

Json.NET does this...

Dictionary<string, string> values = new Dictionary<string, string>();
values.Add("key1", "value1");
values.Add("key2", "value2");

string json = JsonConvert.SerializeObject(values);
// {
//   "key1": "value1",
//   "key2": "value2"
// }

The easy way and fast way to do this is:

three = [sum(i) for i in zip(first,second)] # [7,9,11,13,15]

Alternatively, you can use numpy sum:

from numpy import sum
three = sum([first,second], axis=0) # array([7,9,11,13,15])

It does work indeed. Issue was with my less compiler. It was compiled in to:

.container {
  min-height: calc(-51vh);
}

Fixed with the following code in less file:

.container {
  min-height: calc(~"100vh - 150px");
}

You can also use the drop_duplicates() instead of unique()

df = pd.DataFrame({'A':[1,1,3,2,6,2,8]})
a = df['A'].drop_duplicates()
a.sort()
print a

You can solve this by simply adding class to modal-header

<div class="modal-header bg-primary text-white">

require(ggplot2)
require(nlme)

set.seed(101)
mp <-data.frame(year=1990:2010)
N <- nrow(mp)

mp <- within(mp,
         {
             wav <- rnorm(N)*cos(2*pi*year)+rnorm(N)*sin(2*pi*year)+5
             wow <- rnorm(N)*wav+rnorm(N)*wav^3
         })

m01 <- gls(wow~poly(wav,3), data=mp, correlation = corARMA(p=1))

Get fitted values (the same as m01$fitted)

fit <- predict(m01)

Normally we could use something like predict(...,se.fit=TRUE) to get the confidence intervals on the prediction, but gls doesn't provide this capability. We use a recipe similar to the one shown at http://glmm.wikidot.com/faq :

V <- vcov(m01)
X <- model.matrix(~poly(wav,3),data=mp)
se.fit <- sqrt(diag(X %*% V %*% t(X)))

Put together a "prediction frame":

predframe <- with(mp,data.frame(year,wav,
                                wow=fit,lwr=fit-1.96*se.fit,upr=fit+1.96*se.fit))

Now plot with geom_ribbon

(p1 <- ggplot(mp, aes(year, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It's easier to see that we got the right answer if we plot against wav rather than year:

(p2 <- ggplot(mp, aes(wav, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It would be nice to do the predictions with more resolution, but it's a little tricky to do this with the results of poly() fits -- see ?makepredictcall.

Could this exception be thrown during an unfinished transaction, where your application is attempting to create an entity with a duplicate field to the identifier you are using to try find a single entity?

In this case the new (duplicate) entity will not be visible in the database as the transaction won't have, and will never be committed to the db. The exception will still be thrown however.

The following is not a 100% guaranteed method, and should not at all be attempted for scripting. But some times it is good enough for quick interactive shell usage. A file file glob like

[abc]*

(which will match all files with names starting with a, b or c) can be negated by inserting a "^" character first, i.e.

[^abc]*

I sometimes use this for not matching the "lost+found" directory, like for instance:

mv /mnt/usbdisk/[^l]* /home/user/stuff/.

Of course if there are other files starting with l I have to process those afterwards.

$files = glob('uploads/*');
$count = 0;
$totalCount = 0;
$subFileCount = 0;
foreach ($files as $file) 
{  
    global $count, $totalCount;
    if(is_dir($file))
    {
        $totalCount += getFileCount($file);
    }
    if(is_file($file))
    {
        $count++;  
    }  
}

function getFileCount($dir)
{
    global $subFileCount;
    if(is_dir($dir))
    {
        $subfiles = glob($dir.'/*');
        if(count($subfiles))
        {      
            foreach ($subfiles as $file) 
            {
                getFileCount($file);
            }
        }
    }
    if(is_file($dir))
    {
        $subFileCount++;
    }
    return $subFileCount;
}

$totalFilesCount = $count + $totalCount; 
echo 'Total Files Count ' . $totalFilesCount;

You may use ng-include to avoid using nested ng-views.

http://docs.angularjs.org/api/ng/directive/ngInclude
http://plnkr.co/edit/ngdoc:example-example39@snapshot?p=preview

My index page I use ng-view. Then on my sub pages which I need to have nested frames. I use ng-include. The demo shows a dropdown. I replaced mine with a link ng-click. In the function I would put $scope.template = $scope.templates[0]; or $scope.template = $scope.templates[1];

$scope.clickToSomePage= function(){
  $scope.template = $scope.templates[0];
};

I used:

var save_and_add = function(){
    tinyMCE.triggerSave();
    $('.new_multi_text_block_item').submit();
};

This is all you need to do.

Another possibility is too many threads. We just ran into this error message when running a test harness against an app that uses a thread pool. We used

watch -n 5 -d "ps -eL <java_pid> | wc -l"

to watch the ongoing count of Linux native threads running within the given Java process ID. After this hit about 1,000 (for us--YMMV), we started getting the error message you mention.

Why should you abort the request?

If each request takes more than five seconds, what will happen?

You shouldn't abort the request if the parameter passing with the request is not changing. eg:- the request is for retrieving the notification data. In such situations, The nice approach is that set a new request only after completing the previous Ajax request.

$(document).ready(

    var fn = function(){

        $.ajax({
            url: 'ajax/progress.ftl',
            success: function(data) {
                //do something
            },

            complete: function(){setTimeout(fn, 500);}
        });
    };

     var interval = setTimeout(fn, 500);

);

I just had the same issue on my .net core site. The accepted answer didn't work for me but i found that a combination of ReferenceLoopHandling.Ignore and PreserveReferencesHandling.Objects fixed it.

//serialize item
var serializedItem = JsonConvert.SerializeObject(data, Formatting.Indented, 
new JsonSerializerSettings
{
     PreserveReferencesHandling = PreserveReferencesHandling.Objects,
     ReferenceLoopHandling = ReferenceLoopHandling.Ignore
});

You must use OverridePendingTransition method to achieve it, which is in the Activity class. Sample Animations in the apidemos example's res/anim folder. Check it. More than check the demo in ApiDemos/App/Activity/animation.

Example:

@Override
public void onResume(){
    // TODO LC: preliminary support for views transitions
    this.overridePendingTransition(R.anim.in_from_right, R.anim.out_to_left);
}

Alexy's answer almost worked for me except that I was getting this error:

timebase 1/90000 not supported by MPEG 4 standard, the maximum admitted value for the timebase denominator is 65535

I just had to add a parameter (-r 65535/2733) to the command and it worked. The full command was thus:

ffmpeg -i in.mp4 -vf "transpose=1" -r 65535/2733 out.mp4

I wanted a different look of my website for width screen and small screen. I have made 2 CSS files. In Java I choose which of the 2 CSS file is used depending on the screen width. I use the PHP function echo with in the echo-function some javascript.

my code in the <header> section of my PHP-file:

<?php
echo "

    if ( window.innerWidth > 400)
            { document.write('<link href=\"kekemba_resort_stylesheetblog-jun2018.css\" rel=\"stylesheet\" type=\"text/css\">'); }
    else
            { document.write('<link href=\"kekemba_resort_stylesheetblog-jun2018small.css\" rel=\"stylesheet\" type=\"text/css\">'); }
</script>
";

In XMLHttpRequest, using XMLHttpRequest.responseText may raise the exception like below

 Failed to read the \'responseText\' property from \'XMLHttpRequest\': 
 The value is only accessible if the object\'s \'responseType\' is \'\' 
 or \'text\' (was \'arraybuffer\')

Best way to access the response from XHR as follows

function readBody(xhr) {
    var data;
    if (!xhr.responseType || xhr.responseType === "text") {
        data = xhr.responseText;
    } else if (xhr.responseType === "document") {
        data = xhr.responseXML;
    } else {
        data = xhr.response;
    }
    return data;
}

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
    if (xhr.readyState == 4) {
        console.log(readBody(xhr));
    }
}
xhr.open('GET', 'http://www.google.com', true);
xhr.send(null);

When dealing with mocking lists and iterating them, I always use something like:

@Spy
private List<Object> parts = new ArrayList<>();

As indicated at Python Mock object with method called multiple times

A solution is to write my own side_effect

def my_side_effect(*args, **kwargs):
    if args[0] == 42:
        return "Called with 42"
    elif args[0] == 43:
        return "Called with 43"
    elif kwargs['foo'] == 7:
        return "Foo is seven"

mockobj.mockmethod.side_effect = my_side_effect

That does the trick

This is because the previous month has less days than the current month. I've fixed this by first checking if the previous month has less days that the current and changing the calculation based on it.

If it has less days get the last day of -1 month else get the current day -1 month:

if (date('d') > date('d', strtotime('last day of -1 month')))
{
    $first_end = date('Y-m-d', strtotime('last day of -1 month'));
}
else
{
    $first_end = date('Y-m-d', strtotime('-1 month'));
}

Hopefully a simple explanation : -

onStart() -> called when the activity becomes visible, but might not be in the foreground (e.g. an AlertFragment is on top or any other possible use case).

onResume() -> called when the activity is in the foreground, or the user can interact with the Activity.

You can also convert by creating a dictionary of elements and then directly converting to a data frame:

import xml.etree.ElementTree as ET
import pandas as pd

# Contents of test.xml
# <?xml version="1.0" encoding="utf-8"?> <tags>   <row Id="1" TagName="bayesian" Count="4699" ExcerptPostId="20258" WikiPostId="20257" />   <row Id="2" TagName="prior" Count="598" ExcerptPostId="62158" WikiPostId="62157" />   <row Id="3" TagName="elicitation" Count="10" />   <row Id="5" TagName="open-source" Count="16" /> </tags>

root = ET.parse('test.xml').getroot()

tags = {"tags":[]}
for elem in root:
    tag = {}
    tag["Id"] = elem.attrib['Id']
    tag["TagName"] = elem.attrib['TagName']
    tag["Count"] = elem.attrib['Count']
    tags["tags"]. append(tag)

df_users = pd.DataFrame(tags["tags"])
df_users.head()

It's an old question but seems to me it wasn't completely answered, and I needed this information too so I'll post my answer.

If you want to use the Google Api Client Library, then you just need to have an access token that includes the refresh token in it, and then - even though the access token will expire after an hour - the library will refresh the token for you automatically.

In order to get an access token with a refresh token, you just need to ask for the offline access type (for example in PHP: $client->setAccessType("offline");) and you will get it. Just keep in mind you will get the access token with the refresh token only in the first authorization, so make sure to save that access token in the first time, and you will be able to use it anytime.

Hope that helps anyone :-)

I have had this error when connecting to a RabbitMQ MQTT server via TLS. I'm pretty sure the server is broken but anyway it worked with OpenSSL 1.0.1, but not OpenSSL 1.0.2.

You can check your version in Python using this:

import ssl
ssl.OPENSSL_VERSION

I'm not sure how to downgrade OpenSSL within Python (it seems to be statically linked on Windows at least), other than using an older version of Python.

Simply: It's a warning by which the compiler indicates that it cannot ensure type safety.

JPA service method for example:

@SuppressWarnings("unchecked")
public List<User> findAllUsers(){
    Query query = entitymanager.createQuery("SELECT u FROM User u");
    return (List<User>)query.getResultList();
}

If I didn'n anotate the @SuppressWarnings("unchecked") here, it would have a problem with line, where I want to return my ResultList.

In shortcut type-safety means: A program is considered type-safe if it compiles without errors and warnings and does not raise any unexpected ClassCastException s at runtime.

I build on http://www.angelikalanger.com/GenericsFAQ/FAQSections/Fundamentals.html

When you go back to a previous version,

$ git checkout HEAD~2

9820632 Fixed a bug #33
...

master can be replaced with another branch name.

Then checkout it, you'll be able to get back to the feature.

Add a datatable into session:

DataTable Tissues = new DataTable();

Tissues = dal.returnTissues("TestID", "TestValue");// returnTissues("","") sample     function for adding values


Session.Add("Tissues", Tissues);

Retrive that datatable from session:

DataTable Tissues = Session["Tissues"] as DataTable

or

DataTable Tissues = (DataTable)Session["Tissues"];

Seems the most foolproof way to start with a UTC date is to create a new Date object and use the setUTC… methods to set it to the date/time you want.

Then the various toLocale…String methods will provide localized output.

Example:

// This would come from the server._x000D_
// Also, this whole block could probably be made into an mktime function._x000D_
// All very bare here for quick grasping._x000D_

The below code helps to get the details of elements from the specific form with the form id,

$('#formId input, #formId select').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);

The below code helps to get the details of elements from all the forms which are place in the loading page,

$('form input, form select').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);

The below code helps to get the details of elements which are place in the loading page even when the element is not place inside the tag,

$('input, select').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);

NOTE: We add the more element tag name what we need in the object list like as below,

Example: to get name of attribute "textarea",

$('input, select, textarea').each(
    function(index){  
        var input = $(this);
        alert('Type: ' + input.attr('type') + 'Name: ' + input.attr('name') + 'Value: ' + input.val());
    }
);

You are passing hello() as a string, also hello() means execute hello immediately.

try

onClick={hello}

There is no "better" but the more common one is ||. They have different precedence and || would work like one would expect normally.

See also: Logical operators (the following example is taken from there):

// The result of the expression (false || true) is assigned to $e
// Acts like: ($e = (false || true))
$e = false || true;

// The constant false is assigned to $f and then true is ignored
// Acts like: (($f = false) or true)
$f = false or true;

In this case, you could use life to reference the parent object. Or you could store a reference to life in the users object. There can't be a fixed parent available to you in the language, because users is just a reference to an object, and there could be other references...

var death = { residents : life.users };
life.users.smallFurryCreaturesFromAlphaCentauri = { exist : function() {} };
// death.residents.smallFurryCreaturesFromAlphaCentauri now exists
//  - because life.users references the same object as death.residents!

You might find it helpful to use something like this:

function addChild(ob, childName, childOb)
{
   ob[childName] = childOb;
   childOb.parent = ob;
}

var life= {
        mameAndDestroy : function(group){ },
        kiss : function(group){ }
};

addChild(life, 'users', {
   guys : function(){ this.parent.mameAndDestroy(this.girls); },
   girls : function(){ this.parent.kiss(this.boys); },
   });

// life.users.parent now exists and points to life

You can use many different queries to check if a table exists. Below is a comparison between several:

mysql_query('select 1 from `table_name` group by 1'); or  
mysql_query('select count(*) from `table_name`');

mysql_query("DESCRIBE `table_name`");  
70000   rows: 24ms  
1000000 rows: 24ms  
5000000 rows: 24ms

mysql_query('select 1 from `table_name`');  
70000   rows: 19ms  
1000000 rows: 23ms  
5000000 rows: 29ms

mysql_query('select 1 from `table_name` group by 1'); or  
mysql_query('select count(*) from `table_name`');  
70000   rows: 18ms  
1000000 rows: 18ms  
5000000 rows: 18ms  

These benchmarks are only averages:

// Try this to download any file. laravel 5.*

// you need to use facade "use Illuminate\Http\Response;"

public function getDownload()
{

//PDF file is stored under project/public/download/info.pdf

    $file= public_path(). "/download/info.pdf";   

    return response()->download($file);
}

I was getting the below as well trying to get out to github.com as our proxy re-writes the HTTPS connection with their self-signed cert:

no peer certificate available No client certificate CA names sent

In my output there was also:

Protocol : TLSv1.3

I added -tls1_2 and it worked fine and now I can see which CA it is using on the outgoing request. e.g.:
openssl s_client -connect github.com:443 -tls1_2

In regards to Python optimization, in addition to using PyPy (for pretty impressive speed-ups with zero change to your code), you could use PyPy's translation toolchain to compile an RPython-compliant version, or Cython to build an extension module, both of which are faster than the C version in my testing, with the Cython module nearly twice as fast. For reference I include C and PyPy benchmark results as well:

The RPython version has a couple of key changes. To translate into a standalone program you need to define your target, which in this case is the main function. It's expected to accept sys.argv as it's only argument, and is required to return an int. You can translate it by using translate.py, % translate.py euler12-rpython.py which translates to C and compiles it for you.

# euler12-rpython.py

import math, sys

def factorCount(n):
    square = math.sqrt(n)
    isquare = int(square)
    count = -1 if isquare == square else 0
    for candidate in xrange(1, isquare + 1):
        if not n % candidate: count += 2
    return count

def main(argv):
    triangle = 1
    index = 1
    while factorCount(triangle) < 1001:
        index += 1
        triangle += index
    print triangle
    return 0

if __name__ == '__main__':
    main(sys.argv)

def target(*args):
    return main, None

The Cython version was rewritten as an extension module _euler12.pyx, which I import and call from a normal python file. The _euler12.pyx is essentially the same as your version, with some additional static type declarations. The setup.py has the normal boilerplate to build the extension, using python setup.py build_ext --inplace.

# _euler12.pyx
from libc.math cimport sqrt

cdef int factorCount(int n):
    cdef int candidate, isquare, count
    cdef double square
    square = sqrt(n)
    isquare = int(square)
    count = -1 if isquare == square else 0
    for candidate in range(1, isquare + 1):
        if not n % candidate: count += 2
    return count

cpdef main():
    cdef int triangle = 1, index = 1
    while factorCount(triangle) < 1001:
        index += 1
        triangle += index
    print triangle

# euler12-cython.py
import _euler12
_euler12.main()

# setup.py
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext

ext_modules = [Extension("_euler12", ["_euler12.pyx"])]

setup(
  name = 'Euler12-Cython',
  cmdclass = {'build_ext': build_ext},
  ext_modules = ext_modules
)

I honestly have very little experience with either RPython or Cython, and was pleasantly surprised at the results. If you are using CPython, writing your CPU-intensive bits of code in a Cython extension module seems like a really easy way to optimize your program.

var is used like public .if a varable is declared like this in a class var $a; if means its scope is public for the class. in simplea words var ~public

Swift 3: When you want to remove trailing string:

func replaceSuffix(_ suffix: String, replacement: String) -> String {
    if hasSuffix(suffix) {
        let sufsize = suffix.count < count ? -suffix.count : 0
        let toIndex = index(endIndex, offsetBy: sufsize)
        return substring(to: toIndex) + replacement
    }
    else
    {
        return self
    }
}

example how i made it , After i fill a Maximum length it will blur from my Field (and the Keyboard will disappear ) , if you have more than one field , you can just add the line that i add '//'

var MaxLength = 8;
    $(document).ready(function () {
        $('#MyTB').keyup(function () {
            if ($(this).val().length >= MaxLength) {
               $('#MyTB').blur();
             //  $('#MyTB2').focus();
         }
          }); });

With absolute or relative positioning, you can do all sorts of overlapping. You've probably want the logo to be styled as such:

div#logo {
  position: absolute;
  left: 100px; // or whatever
}

Note: absolute position has its eccentricities. You'll probably have to experiment a little, but it shouldn't be too hard to do what you want.

Symlinked directories:

It's important to note what happens when there is a directory which is a soft link. Any Git pull with an update removes the link and makes it a normal directory. This is what I learnt hard way. Some insights here and here.

Example

Before

 ls -l
 lrwxrwxrwx 1 admin adm   29 Sep 30 15:28 src/somedir -> /mnt/somedir

git add/commit/push

It remains the same

After git pull AND some updates found

 drwxrwsr-x 2 admin adm 4096 Oct  2 05:54 src/somedir

In the latest version of iOS this method is now deprecated. To support both iOS 7 and iOS 8 use:

UIApplication *application = [UIApplication sharedApplication];

BOOL enabled;

// Try to use the newer isRegisteredForRemoteNotifications otherwise use the enabledRemoteNotificationTypes.
if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
{
    enabled = [application isRegisteredForRemoteNotifications];
}
else
{
    UIRemoteNotificationType types = [application enabledRemoteNotificationTypes];
    enabled = types & UIRemoteNotificationTypeAlert;
}

As the error message says in the last line: the module models in the file c:\projects\mysite..\mysite\polls\models.py contains no class model. This error occurs in the definition of the Poll class:

class Poll(models.model):

Either the class model is misspelled in the definition of the class Poll or it is misspelled in the module models. Another possibility is that it is completely missing from the module models. Maybe it is in another module or it is not yet implemented in models.

checked :

public Constructor(Class<E> c, int length) {

    elements = (E[]) Array.newInstance(c, length);
}

or unchecked :

}

Just do this:

                    ;Trusted_Connection=yes")

df = pd.read_sql("SELECT * FROM myTableName", cnxn) 
df.head()

To break a $.each or $(selector).each loop, you have to return false in the loop callback.

Returning true skips to the next iteration, equivalent to a continue in a normal loop.

$.each(array, function(key, value) { 
    if(value === "foo") {
        return false; // breaks
    }
});

// or

$(selector).each(function() {
  if (condition) {
    return false;
  }
});

The other answers don't seem to address why close() is really necessary? * 2

Doubt on the answer "HttpClient resource deallocation".

It is mentioned in old 3.x httpcomponents doc, which is long back and has a lot difference from 4.x HC. Besides the explanation is so brief that doesn't say what this underlying resource is.

I did some research on 4.5.2 release source code, found the implementations of CloseableHttpClient:close() basically only closes its connection manager.

(FYI) That's why when you use a shared PoolingClientConnectionManager and call client close(), exception java.lang.IllegalStateException: Connection pool shut down will occur. To avoid, setConnectionManagerShared works.

I prefer not do CloseableHttpClient:close() after every single request

I used to create a new http client instance when doing request and finally close it. In this case, it'd better not to call close(). Since, if connection manager doesn't have "shared" flag, it'll be shutdown, which is too expensive for a single request.

In fact, I also found in library clj-http, a Clojure wrapper over Apache HC 4.5, doesn't call close() at all. See func request in file core.clj

Mark Rendle posted this as a comment, I wanted to post it as an answer since it's the only solution that has worked so far to return the success and the error-codes json results from the Google reCaptcha response.

Declare @phoneNumber int

select @phoneNumber=Isnull('08041159620',0);

Give error :

The conversion of the varchar value '8041159620' overflowed an int column.: select cast('8041159620' as int)

AS

Integer is defined as :

Integer (whole number) data from -2^31 (-2,147,483,648) through 2^31 - 1 (2,147,483,647). Storage size is 4 bytes. The SQL-92 synonym for int is integer.

Solution

Declare @phoneNumber bigint

Assuming your stream is not backed by a socket (so you can't use Socket.setSoTimeout()), I think the standard way of solving this type of problem is to use a Future.

Suppose I have the following executor and streams:

    ExecutorService executor = Executors.newFixedThreadPool(2);
    final PipedOutputStream outputStream = new PipedOutputStream();
    final PipedInputStream inputStream = new PipedInputStream(outputStream);

I have writer that writes some data then waits for 5 seconds before writing the last piece of data and closing the stream:

    Runnable writeTask = new Runnable() {
        @Override
        public void run() {
            try {
                outputStream.write(1);
                outputStream.write(2);
                Thread.sleep(5000);
                outputStream.write(3);
                outputStream.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    };
    executor.submit(writeTask);

The normal way of reading this is as follows. The read will block indefinitely for data and so this completes in 5s:

    long start = currentTimeMillis();
    int readByte = 1;
    // Read data without timeout
    while (readByte >= 0) {
        readByte = inputStream.read();
        if (readByte >= 0)
            System.out.println("Read: " + readByte);
    }
    System.out.println("Complete in " + (currentTimeMillis() - start) + "ms");

which outputs:

Read: 1
Read: 2
Read: 3
Complete in 5001ms

If there was a more fundamental problem, like the writer not responding, the reader would block for ever. If I wrap the read in a future, I can then control the timeout as follows:

    int readByte = 1;
    // Read data with timeout
    Callable<Integer> readTask = new Callable<Integer>() {
        @Override
        public Integer call() throws Exception {
            return inputStream.read();
        }
    };
    while (readByte >= 0) {
        Future<Integer> future = executor.submit(readTask);
        readByte = future.get(1000, TimeUnit.MILLISECONDS);
        if (readByte >= 0)
            System.out.println("Read: " + readByte);
    }

which outputs:

Read: 1
Read: 2

I can catch the TimeoutException and do whatever cleanup I want.

The sequel gem adds an update_or_create method which seems to do what you're looking for.

You can use a custom format string:

DateTime d = DateTime.Now;
string dateString = d.ToString("yyyyMMddHHmmss");

Substitute "hh" for "HH" if you do not want 24-hour clock time.

You can use axis:

> axis(side=1, at=c(0:23))

That is, something like this:

plot(0:23, d, type='b', axes=FALSE)
axis(side=1, at=c(0:23))
axis(side=2, at=seq(0, 600, by=100))
box()

Try to use this:

HTML:

<input ID="fileUpload1" runat="server" type="file">

JavaScript:

$("#fileUpload1").on('change',function() {
    alert('Works!!');
});

?

Some notes to complement the ALTER DATABASE process:

1) You can obtain a full list of databases with logical names and full paths of MDF and LDF files:

   USE master SELECT name, physical_name FROM sys.master_files

2) You can move manually the files with CMD move command:

Move "Source" "Destination"

Example:

md "D:\MSSQLData"
Move "C:\test\SYSADMIT-DB.mdf" "D:\MSSQLData\SYSADMIT-DB_Data.mdf"
Move "C:\test\SYSADMIT-DB_log.ldf" "D:\MSSQLData\SYSADMIT-DB_log.ldf"

3) You should change the default database path for new databases creation. The default path is obtained from the Windows registry.

You can also change with T-SQL, for example, to set default destination to: D:\MSSQLData

USE [master]

GO

EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultData', REG_SZ, N'D:\MSSQLData'

GO

EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultLog', REG_SZ, N'D:\MSSQLData'

Check the error_reporting, display_errors and display_startup_errors settings in your php.ini file. They should be set to E_ALL and "On" respectively (though you should not use display_errors on a production server, so disable this and use log_errors instead if/when you deploy it). You can also change these settings (except display_startup_errors) at the very beginning of your script to set them at runtime (though you may not catch all errors this way):

error_reporting(E_ALL);
ini_set('display_errors', 'On');

After that, restart server.

You need to do a few things:

1. You first need to check if the constrain exits in the information schema
2. then you need to query by joining the sys.default_constraints and sys.columns if the columns and default_constraints have the same object ids
3. When you join in step 2, you would get the constraint name from default_constraints. You drop that constraint. Here is an example of one such drops I did.

-- 1. Remove constraint and drop column
IF EXISTS(SELECT *
          FROM INFORMATION_SCHEMA.COLUMNS
          WHERE TABLE_NAME = N'TABLE_NAME'
            AND COLUMN_NAME = N'LOWER_LIMIT')
   BEGIN
    DECLARE @sql NVARCHAR(MAX)
    WHILE 1=1
        BEGIN
            SELECT TOP 1 @sql = N'alter table [TABLE_NAME] drop constraint ['+dc.name+N']'
            FROM sys.default_constraints dc
            JOIN sys.columns c
            ON c.default_object_id = dc.object_id
            WHERE dc.parent_object_id = OBJECT_ID('[TABLE_NAME]') AND c.name = N'LOWER_LIMIT'
            IF @@ROWCOUNT = 0
                BEGIN
                    PRINT 'DELETED Constraint on column LOWER_LIMIT'
                    BREAK
                END
        EXEC (@sql)
    END;
    ALTER TABLE TABLE_NAME DROP COLUMN LOWER_LIMIT;
    PRINT 'DELETED column LOWER_LIMIT'
   END
ELSE
   PRINT 'Column LOWER_LIMIT does not exist'
GO

if you are using Java SE 8, then this might be of help.

//create a comparator object using a Lambda expression
Comparator<Double> compareDouble = (d1, d2) -> d1.compareTo(d2);

//Sort the Collection in this case 'testList' in reverse order
Collections.sort(testList, Collections.reverseOrder(compareDouble));

//print the sorted list using method reference only applicable in SE 8
testList.forEach(System.out::println);

What you are doing will not work for root user. Maybe you are running your services as root and hence you don't get to see the change.

To increase the ulimit for root user you should replace the * by root. * does not apply for root user. Rest is the same as you did. I will re-quote it here.

Add the following lines to the file: /etc/security/limits.conf

root soft  nofile 40000

root hard  nofile 40000

And then add following line in the file: /etc/pam.d/common-session

session required pam_limits.so

This will update the ulimit for root user. As mentioned in comments, you may don't even have to reboot to see the change.

It's been a while, but last time I had something similar:

ROLLBACK TRAN

or trying to

COMMIT

what had allready been done free'd everything up so I was able to clear things out and start again.

Remove the if keyword. It should just be predicate ? true_result : false_result.

Also ? : is called ternary operator.

serialize() is the function you are looking for. It will return a string representation of its input array or object in a PHP-specific internal format. The string may be converted back to its original form with unserialize().

But beware, that not all objects are serializable, or some may be only partially serializable and unable to be completely restored with unserialize().

$array = array(1,2,3,'foo');
echo serialize($array);

Yes.

Constructors are nothing more than special methods, and can throw exceptions like any other method.

EDIT:

What I've noticed in this type of questions that quite everyone suggest to remove the last char of given string. But this does not fulfill the definition of Trim method.

Trim - Removes all occurrences of white space characters from the beginning and end of this instance.

MSDN-Trim

Under this definition removing only last character from string is bad solution.

So if we want to "Trim last character from string" we should do something like this

Example as extension method:

public static class MyExtensions
{
  public static string TrimLastCharacter(this String str)
  {
     if(String.IsNullOrEmpty(str)){
        return str;
     } else {
        return str.TrimEnd(str[str.Length - 1]);
     }
  }
}

Note if you want to remove all characters of the same value i.e(!!!!)the method above removes all existences of '!' from the end of the string, but if you want to remove only the last character you should use this :

else { return str.Remove(str.Length - 1); }

On the contrary of @Thomas Eding answer:

If I forget to declare myVar in my code, then I'll get myVar is not defined.

Let's take a real example:

I've a variable name, but I am not sure if it is declared somewhere or not.

Then @Anurag's answer will help:

var myVariableToCheck = 'myVar';
if (window[myVariableToCheck] === undefined)
    console.log("Not declared or declared, but undefined.");

// Or you can check it directly 
if (window['myVar'] === undefined) 
    console.log("Not declared or declared, but undefined.");

I solved the problem by cat'ing all the pems together:

cat cert.pem chain.pem fullchain.pem >all.pem
openssl pkcs12 -export -in all.pem -inkey privkey.pem -out cert_and_key.p12 -name tomcat -CAfile chain.pem -caname root -password MYPASSWORD
keytool -importkeystore -deststorepass MYPASSWORD -destkeypass MYPASSWORD -destkeystore MyDSKeyStore.jks -srckeystore cert_and_key.p12 -srcstoretype PKCS12 -srcstorepass MYPASSWORD -alias tomcat
keytool -import -trustcacerts -alias root -file chain.pem -keystore MyDSKeyStore.jks -storepass MYPASSWORD

(keytool didn't know what to do with a PKCS7 formatted key)

I got all the pems from letsencrypt

This will replace consecutive spaces with one space (but not tab).

tr -s '[:blank:]'

This will replace consecutive spaces with a tab.

tr -s '[:blank:]' '\t'

There is a new property in CSS3 that you can use to change the way the box model calculates width/height, it's called box-sizing.

By setting this property with the value "border-box" it makes whichever element you apply it to not stretch when you add a padding or border. If you define something with 100px width, and 10px padding, it will still be 100px wide.

box-sizing: border-box;

See here for browser support. It does not work for IE7 and lower, however, I believe that Dean Edward's IE7.js adds support for it. Enjoy :)

If you want to check if any item in the list violates a condition use all:

if all([x[2] == 0 for x in lista]):
    # Will run if all elements in the list has x[2] = 0 (use not to invert if necessary)

To remove all elements not matching, use filter

# Will remove all elements where x[2] is 0
listb = filter(lambda x: x[2] != 0, listb)

You need only to write:

GRANT DBA TO NewDBA;

Because this already makes the user a DB Administrator

You can use a deadlock graph and gather the information you require from the log file.

The only other way I could suggest is digging through the information by using EXEC SP_LOCK (Soon to be deprecated), EXEC SP_WHO2 or the sys.dm_tran_locks table.

The Popup class might be better than the Stage class, depending on what you want. Stage is either modal (you can't click on anything else in your app) or it vanishes if you click elsewhere in your app (because it's a separate window). Popup stays on top but is not modal.

See this Popup Window example.

How about a very simple method

    +call your while loop in a function 
     - set your value inside (nonsense, but shows the example)
     - return your value inside 
    +capture your value outside
    +set outside
    +display outside


    #!/bin/bash
    # set -e
    # set -u
    # No idea why you need this, not using here

    foo=0
    bar="hello"

    if [[ "$bar" == "hello" ]]
    then
        foo=1
        echo "Setting  \$foo to $foo"
    fi

    echo "Variable \$foo after if statement: $foo"

    lines="first line\nsecond line\nthird line"

    function my_while_loop
    {

    echo -e $lines | while read line
    do
        if [[ "$line" == "second line" ]]
        then
        foo=2; return 2;
        echo "Variable \$foo updated to $foo inside if inside while loop"
        fi

        echo -e $lines | while read line

    if [[ "$line" == "second line" ]]
    then

JSFIDDLE

I prefer to have symlinks in the home directory, in this case at least. Here's how I have things setup:

: cat ~/.bash_profile | grep PATH
# places ~/bin first in PATH
export PATH=~/bin:$PATH

So I symlinked to the VSCode binary like so:

ln -s /Applications/Visual\ Studio\ Code.app/Contents/Resources/app/bin/code ~/bin/code

Now I can issue code . in whichever directory I desire.

What is it about your existing query that you don't like? If you are concerned that DISTINCT across two columns does not return just the unique permutations why not try it?

It certainly works as you might expect in Oracle.

SQL> select distinct deptno, job from emp
  2  order by deptno, job
  3  /

    DEPTNO JOB
---------- ---------
        10 CLERK
        10 MANAGER
        10 PRESIDENT
        20 ANALYST
        20 CLERK
        20 MANAGER
        30 CLERK
        30 MANAGER
        30 SALESMAN

9 rows selected.


SQL> select count(*) from (
  2  select distinct deptno, job from emp
  3  )
  4  /

  COUNT(*)
----------
         9

SQL>

edit

I went down a blind alley with analytics but the answer was depressingly obvious...

SQL> select count(distinct concat(deptno,job)) from emp
  2  /

COUNT(DISTINCTCONCAT(DEPTNO,JOB))
---------------------------------
                                9

Given the following data the concatenating solution provided above will miscount:

col1  col2
----  ----
A     AA
AA    A

So we to include a separator...

select col1 + '*' + col2 from t23
/

Obviously the chosen separator must be a character, or set of characters, which can never appear in either column.

You can also try this:

try {
    Class res = R.drawable.class;
    Field field = res.getField("drawableName");
    int drawableId = field.getInt(null);
}
catch (Exception e) {
    Log.e("MyTag", "Failure to get drawable id.", e);
}

I have copied this source codes from below URL. Based on tests done in this page, it is 5 times faster than getIdentifier(). I also found it more handy and easy to use. Hope it helps you as well.

Datetimes are comparable; so you can use max(datetimes_list) and min(datetimes_list)

This happened to me when I accidentally defined two entities with the same persistent database table. In one of the tables the column in question did exist, in the other not. When attempting to persist an object (of the type referring to the wrong underlying database table), this error occurred.

It should be text-align, not align

If you want the .DS_Store files to become invisible (they still exist but can't be seen) then run the following command in the "Terminal" window:

defaults write com.apple.finder AppleShowAllFiles FALSE; killall Finder

This will set the system default to stop showing these files on your Desktop and elsewhere. It will also restart the Finder in order to make this change visible (especially on your Desktop).

I'll make a strong suggestion for rvm.

It's a great way to manage multiple Rubies and gems sets without colliding with the system version.

I'll add that now (4/2/2013), I use rbenv a lot, because my needs are simple. RVM is great, but it's got a lot of capability I never need, so I have it on some machines and rbenv on my desktop and laptop. It's worth checking out both and seeing which works best for your needs.

You can simply add this CSS to your header

<link href='http://netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.css' rel='stylesheet' type='text/css'>

next add this code in place where you want to display a glyph symbol.

<div class="fa fa-search"></div> <!-- smaller -->
<div class="fa fa-search fa-2x"></div> <!-- bigger -->

jQuery and console.log are unrelated entities, although useful when used together.

If you use a browser's built-in dev tools, console.log will log information about the object being passed to the log function.

If the console is not active, logging will not work, and may break your script. Be certain to check that the console exists before logging:

if (window.console) console.log('foo');

The shortcut form of this might be seen instead:

window.console&&console.log('foo');

There are other useful debugging functions as well, such as debug, dir and error. Firebug's wiki lists the available functions in the console api.

This uses twitter bootstrap 3.x with one css class to get labels to sit on top of the inputs. Here's a fiddle link, make sure to expand results panel wide enough to see effect.

HTML:

  <div class="row myform">
     <div class="col-md-12">
        <form name="myform" role="form" novalidate>
           <div class="form-group">
              <label class="control-label" for="fullName">Address Line</label>
              <input required type="text" name="addr" id="addr" class="form-control" placeholder="Address"/>
           </div>

           <div class="form-inline">
              <div class="form-group">
                 <label>State</label>
                 <input required type="text" name="state" id="state" class="form-control" placeholder="State"/>
              </div>

              <div class="form-group">
                 <label>ZIP</label>
                 <input required type="text" name="zip" id="zip" class="form-control" placeholder="Zip"/>
              </div>
           </div>

           <div class="form-group">
              <label class="control-label" for="country">Country</label>
              <input required type="text" name="country" id="country" class="form-control" placeholder="country"/>
           </div>
        </form>
     </div>
  </div>

CSS:

.myform input.form-control {
   display: block;  /* allows labels to sit on input when inline */
   margin-bottom: 15px; /* gives padding to bottom of inline inputs */
}

As Hogan notes above, use an AND instead of &. See this tutorial for more info.

success only fires if the AJAX call is successful, i.e. ultimately returns a HTTP 200 status. error fires if it fails and complete when the request finishes, regardless of success.

In jQuery 1.8 on the jqXHR object (returned by $.ajax) success was replaced with done, error with fail and complete with always.

However you should still be able to initialise the AJAX request with the old syntax. So these do similar things:

// set success action before making the request
$.ajax({
  url: '...',
  success: function(){
    alert('AJAX successful');
  }
});

// set success action just after starting the request
var jqxhr = $.ajax( "..." )
  .done(function() { alert("success"); });

This change is for compatibility with jQuery 1.5's deferred object. Deferred (and now Promise, which has full native browser support in Chrome and FX) allow you to chain asynchronous actions:

$.ajax("parent").
    done(function(p) { return $.ajax("child/" + p.id); }).
    done(someOtherDeferredFunction).
    done(function(c) { alert("success: " + c.name); });

This chain of functions is easier to maintain than a nested pyramid of callbacks you get with success.

However, please note that done is now deprecated in favour of the Promise syntax that uses then instead:

$.ajax("parent").
    then(function(p) { return $.ajax("child/" + p.id); }).
    then(someOtherDeferredFunction).
    then(function(c) { alert("success: " + c.name); }).
    catch(function(err) { alert("error: " + err.message); });

This is worth adopting because async and await extend promises improved syntax (and error handling):

try {
    var p = await $.ajax("parent");
    var x = await $.ajax("child/" + p.id);
    var c = await someOtherDeferredFunction(x);
    alert("success: " + c.name);
}
catch(err) { 
    alert("error: " + err.message); 
}

Use PHP Document Object Model:

<?php
   $str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
   $DOM = new DOMDocument;
   $DOM->loadHTML($str);

   //get all H1
   $items = $DOM->getElementsByTagName('h1');

   //display all H1 text
   for ($i = 0; $i < $items->length; $i++)
        echo $items->item($i)->nodeValue . "<br/>";
?>

This outputs as:

 T1
 T2
 T3

[EDIT]: After OP Clarification:

If you want the content like Lorem ipsum. etc, you can directly use this regex:

<?php
   $str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
   echo preg_replace("#<h1.*?>.*?</h1>#", "", $str);
?>

this outputs:

Lorem ipsum.The quick red fox...... jumps over the lazy brown FROG

check your project build in jdk 9 or not above that eclipse is having some issues with the modules. Change it to jdk 9 then it will run fine

A simple function without using a class:

Color _colorFromHex(String hexColor) {
  final hexCode = hexColor.replaceAll('#', '');
  return Color(int.parse('FF$hexCode', radix: 16));
}

You can use it like this:

Color color1 = _colorFromHex("b74093");
Color color2 = _colorFromHex("#b74093");

This is because the path of image is wrong or the name of image you write is incorrect .

how to check? first try to print the image using print(img) if it prints 'None' that means you have given wrong image path correct that path and try again.

It is working, but it wont modify the caller object, but returning a new String.
So you just need to assign it to a new String variable, or to itself:

string = string.replace("to", "xyz");

or

String newString = string.replace("to", "xyz");

API Docs

public String replace (CharSequence target, CharSequence replacement) 

Since: API Level 1

Copies this string replacing occurrences of the specified target sequence with another sequence. The string is processed from the beginning to the end.

Parameters

• target the sequence to replace.
• replacement the replacement sequence.

Returns the resulting string.
Throws NullPointerException if target or replacement is null.

You can do that but the changes will affect for new data that is inserted on the database. On the long run follow as suggested above.

Also there are certain tricks you can override the collation, such as parameters for stored procedures or functions, alias data types, and variables are assigned the default collation of the database. To change the collation of an alias type, you must drop the alias and re-create it.

You can override the default collation of a literal string by using the COLLATE clause. If you do not specify a collation, the literal is assigned the database default collation. You can use DATABASEPROPERTYEX to find the current collation of the database.

You can override the server, database, or column collation by specifying a collation in the ORDER BY clause of a SELECT statement.

This could a permission issue. The user needs at least ALTER permission to truncate a table. Another option is to call DELETE FROM instead of TRUNCATE TABLE, but this operation is slower because it writes to the Log file, whereas TRUNCATE does not write to the log file.

The minimum permission required is ALTER on table_name. TRUNCATE TABLE permissions default to the table owner, members of the sysadmin fixed server role, and the db_owner and db_ddladmin fixed database roles, and are not transferable. However, you can incorporate the TRUNCATE TABLE statement within a module, such as a stored procedure, and grant appropriate permissions to the module using the EXECUTE AS clause.

string s = "hello";
char c = s[1];
// now c == 'e'

See also Substring, to return more than one character.

I know this question has been answered but I also see there is another way missing which I would like to cover it.There are multiple ways to achieve this.

1- innerHTML

document.getElementById("ShowButton").innerHTML = 'Show Filter';

You can insert HTML into this. But the disadvantage of this method is, it has cross site security attacks. So for adding text, its better to avoid this for security reasons.

2- innerText

document.getElementById("ShowButton").innerText = 'Show Filter';

This will also achieve the result but its heavy under the hood as it requires some layout system information, due to which the performance decreases. Unlike innerHTML, you cannot insert the HTML tags with this. Check Performance Here

3- textContent

document.getElementById("ShowButton").textContent = 'Show Filter';

This will also achieve the same result but it doesn't have security issues like innerHTML as it doesn't parse HTML like innerText. Besides, it is also light due to which performance increases.

So if a text has to be added like above, then its better to use textContent.

You can do:

timeStamp.toLocalDateTime().toLocalDate();

Note that timestamp.toLocalDateTime() will use the Clock.systemDefaultZone() time zone to make the conversion. This may or may not be what you want.

Get all the outdated packages and create a batch file with the following commands pip install xxx --upgrade for each outdated packages

A bit manual searching but its an alternative way...
Find the Oracle home or where the installation files for Oracle is installed on your linux server.

cd / <-- Goto root directory
find . -print| grep -i dbm*.sql

Result varies on how you installed Oracle but mine displays this

/db/oracle

Goto the folder
