The token has to be placed in an Authorization header according to the following format:

Authorization: Bearer [Token_Value]

Code below:

import urllib2
import json

def get_auth_token():
    """
    get an auth token
    """
    req=urllib2.Request("https://xforce-api.mybluemix.net/auth/anonymousToken")
    response=urllib2.urlopen(req)
    html=response.read()
    json_obj=json.loads(html)
    token_string=json_obj["token"].encode("ascii","ignore")
    return token_string

def get_response_json_object(url, auth_token):
    """
    returns json object with info
    """
    auth_token=get_auth_token()
    req=urllib2.Request(url, None, {"Authorization": "Bearer %s" %auth_token})
    response=urllib2.urlopen(req)
    html=response.read()
    json_obj=json.loads(html)
    return json_obj

For me what works here is to using a version manager such as pyenv, which I strongly recommend to get your project environments and package versions well managed and separate from that of the operative system.

I had this same error after an OS update, but was easily fixed with pyenv install 3.7-dev (the version I use).

Try with subprocess

CurlUrl="curl 'https://www.example.com/' -H 'Connection: keep-alive' -H 'Cache- 
          Control: max-age=0' -H 'Origin: https://www.example.com' -H 'Accept-Encoding: 
          gzip, deflate, br' -H 'Cookie: SESSID=ABCDEF' --data-binary 'Pathfinder' -- 
          compressed"

Use getstatusoutput to store the results

status, output = subprocess.getstatusoutput(CurlUrl)

Be advised that if you're using nodejs there's (at the time of writing) a dependency on libssl 1.0.* - so installing an alternative SSL library will break your nodejs installation.

An alternative solution to installing a different SSL library is that posted in this answer here: https://stackoverflow.com/a/59927568/13564342 to instead install libcurl4-gnutls-dev

sudo apt install libcurl4-gnutls-dev

Since you cannot set value="" within your first option, you'll need to create your own rule using the built-in addMethod() method.

jQuery:

$(document).ready(function () {

    $('#myform').validate({ // initialize the plugin
        rules: {
            year: {
                selectcheck: true
            }
        }
    });

    jQuery.validator.addMethod('selectcheck', function (value) {
        return (value != '0');
    }, "year required");

});

HTML:

<select name="year">
    <option value="0">Year</option>
    <option value="1">1955</option>
    <option value="2">1956</option>
</select>

Working Demo: http://jsfiddle.net/tPRNd/

Original Answer: (Only if you can set value="" within the first option)

To properly validate a select element with the jQuery Validate plugin simply requires that the first option contains value="". So remove the 0 from value="0" and it's fixed.

jQuery:

$(document).ready(function () {

    $('#myform').validate({ // initialize the plugin
        rules: {
            year: {
                required: true,
            }
        }
    });

});

HTML:

<select name="year">
    <option value="">Year</option>
    <option value="1">1955</option>
    <option value="2">1956</option>
</select>

 If strMyString.Tostring.Contains("Something") or strMyString.Tostring.Contains("Something2") Then


     End if

In java you can use setFetchSource like this :

client.prepareSearch(index).setTypes(type)
            .setFetchSource(new String[] { "field1", "field2" }, null)

As a complement to other answers note that you can also put the lang attribute on various HTML tags inside a page. For example to give a hint to the spellchecker that the input text should be in english:

<input ... spellcheck="true" lang="en"> ...

See: https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/lang

I got stuck in 'rebase status', I got

On branch master
Your branch is up to date with 'origin/master'.

You are currently rebasing.
  (all conflicts fixed: run "git rebase --continue")

nothing to commit, working tree clean

but running git rebase --skip yielded error: could not read '.git/rebase-apply/head-name': No such file or directory.

Running rm -fr ".git/rebase-apply" helped.

Note: of course, do it only if you don't care about the rebase or if you're stuck on a previous rebase you don't want anymore.

The ID is only guaranteed to be generated at flush time. Persisting an entity only makes it "attached" to the persistence context. So, either flush the entity manager explicitely:

em.persist(abc);
em.flush();
return abc.getId();

or return the entity itself rather than its ID. When the transaction ends, the flush will happen, and users of the entity outside of the transaction will thus see the generated ID in the entity.

@Override
public ABC addNewABC(ABC abc) {
    abcDao.insertABC(abc);
    return abc;
}

import os
path = "C:/Documents and Settings/flow_model/"

Using np.percentile.

q75, q25 = np.percentile(DataFrame, [75,25])
iqr = q75 - q25

Answer from How do you find the IQR in Numpy?

Use this

 from tensorflow.keras.datasets import imdb

instead of this

 from keras.datasets import imdb

Use wildcards:

cp /home/ankur/folder/* /home/ankur/dest

If you don't want to copy all the files, you can use braces to select files:

cp /home/ankur/folder/{file{1,2},xyz,abc} /home/ankur/dest

This will copy file1, file2, xyz, and abc.

You should read the sections of the bash man page on Brace Expansion and Pathname Expansion for all the ways you can simplify this.

Another thing you can do is cd /home/ankur/folder. Then you can type just the filenames rather than the full pathnames, and you can use filename completion by typing Tab.

If you want to have your code os-unspecific you should use println for each word

System.out.println("I");
System.out.println("am");
System.out.println("a");
System.out.println("boy");

because Windows uses "\r\n" as newline and unixoid systems use just "\n"

println always uses the correct one

This is very very flexible.

You can use Magical Take Photo library.

1. try with compile in gradle

compile 'com.frosquivel:magicaltakephoto:1.0'

2. You need this permission in your manifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA"/>

3. instance the class like this

// "this" is the current activity param

MagicalTakePhoto magicalTakePhoto =  new MagicalTakePhoto(this,ANY_INTEGER_0_TO_4000_FOR_QUALITY);

4. if you need to take picture use the method

magicalTakePhoto.takePhoto("my_photo_name");

5. if you need to select picture in device, try with the method:

magicalTakePhoto.selectedPicture("my_header_name");

6. You need to override the method onActivityResult of the activity or fragment like this:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
     super.onActivityResult(requestCode, resultCode, data);
     magicalTakePhoto.resultPhoto(requestCode, resultCode, data);

     // example to get photo
     // imageView.setImageBitmap(magicalTakePhoto.getMyPhoto());
}

Note: Only with this Library you can take and select picture in the device, this use a min API 15.

If you've installed the WIF SDK, try :

C:\Program Files\Reference Assemblies\Microsoft\Windows Identity Foundation\v3.5\
   Microsoft.IdentityModel.dll

Instead of doing this:

compile "com.android.support:support-v4:18.0.+"

Do this:

compile 'com.android.support:support-v4:18.0.+' 

Worked for me

The error in question may also be caused by disabled JarScanner in tomcat/conf/context.xml.

See also Upgrade from Tomcat 8.0.39 to 8.0.41 results in 'failed to scan' errors.

<JarScanner scanManifest="false"/> allows to avoid both problems.

Assuming you mean that you are trying to use the source command in order to execute SQL statements from a text file, the error number given appears to be passed through from the POSIX layer.

Therefore, using this resource, we can deduce that the error value of 2 means "no such file or directory".

In short, you got the path wrong.

Try providing an absolute path, as it's not clear what the current working directory will be in the context of your MySQL server. You may be assuming that it's the working directory of your shell, but it's not obvious that we should expect this to be true.

This worked for me:

$('#SelectListId').prepend('<option selected></option>').select2({
    placeholder: "Select Month",
    allowClear: true
});

Hope this help :)

If you are using Eclipse , you can try the below 7 steps to get a .exe file for Windows.

Now you have a JAR file. Use java -jar path/jarname.jar to execute.

If you want to convert this to .exe, you can try http://sourceforge.net/projects/launch4j/files/launch4j-3/

STEP7: Give the .xml file an appropriate name and click "Save". The .xml file is standard, don't worry about it. Your executable file will now be created!

Git is just trying to guess for you what you are trying to do. It is making every attempt to preserve unbroken history. Of course, it is not perfect. So git mv allows you to be explicit with your intention and to avoid some errors.

Consider this example. Starting with an empty repo,

git init
echo "First" >a
echo "Second" >b
git add *
git commit -m "initial commit"
mv a c
mv b a
git status

Result:

# On branch master
# Changes not staged for commit:
#   (use "git add/rm <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#   modified:   a
#   deleted:    b
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#   c
no changes added to commit (use "git add" and/or "git commit -a")

Autodetection failed :( Or did it?

$ git add *
$ git commit -m "change"
$ git log c

    change

and then

$ git log --follow c

    initial commit

Now try instead (remember to delete the .git folder when experimenting):

git init
echo "First" >a
echo "Second" >b
git add *
git commit -m "initial commit"
git mv a c
git status

So far so good:

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


git mv b a
git status

Now, nobody is perfect:

# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   modified:   a
#   deleted:    b
#   new file:   c
#

Really? But of course...

git add *
git commit -m "change"
git log c
git log --follow c

...and the result is the same as above: only --follow shows the full history.

Now, be careful with renaming, as either option can still produce weird effects. Example:

git init
echo "First" >a
git add a
git commit -m "initial a"
echo "Second" >b
git add b
git commit -m "initial b"

git mv a c
git commit -m "first move"
git mv b a
git commit -m "second move"

git log --follow a

Contrast it with:

git add a
git commit -m "initial a"
echo "Second" >b
git add b
git commit -m "initial b"

git mv a c
git mv b a

    initial a

Ups... Now the history is going back to initial a instead of initial b, which is wrong. So when we did two moves at a time, Git became confused and did not track the changes properly. By the way, in my experiments the same happened when I deleted/created files instead of using git mv. Proceed with care; you've been warned...

I had a similar problem.

My Problem:

I want to calculate an SVD and need to sort my eigenvalues in descending order. But I want to keep the mapping between eigenvalues and eigenvectors. My eigenvalues were in the first row and the corresponding eigenvector below it in the same column.

So I want to sort a two-dimensional array column-wise by the first row in descending order.

My Solution

a = a[::, a[0,].argsort()[::-1]]

So how does this work?

a[0,] is just the first row I want to sort by.

Now I use argsort to get the order of indices.

I use [::-1] because I need descending order.

Lastly I use a[::, ...] to get a view with the columns in the right order.

the following is that the difference between iterator and listIterator

iterator :

boolean hasNext();
E next();
void remove();

listIterator:

boolean hasNext();
E next();
boolean hasPrevious();
E previous();
int nextIndex();
int previousIndex();
void remove();
void set(E e);
void add(E e);

A note for others who may be using Owl Carousel v 1.3.2:

You can replace the navigation text in the settings where you're enabling the navigation.

navigation:true,

   "<i class='fa fa-chevron-right'></i>"
]

Explanation by analogy

Imagine that you wrote a letter to your pen pal but that you wrote it in different languages each time.

For example, you might have chosen to write your first letter in Tamil, and the second in German etc.

In order for your friend to translate those letters, your friend would need to:

• (i) identify the language type, and
• (ii) and then translate it accordingly. But identifying a language is not that easy - it's going to take a lot of computational energy. It would be much easier if you wrote the language you are sending across on the top of your letter - that would make life a lot easier for your friend.

So then, in order to highlight the language you are writing in, you simple annotate the language (e.g. "French") on the top of your letter.

How would your friend know or be able to read or distinguish between the different language types you are specifying at the top of your letter? That's easy: you agree upon this beforehand.

Tying the analogy back in with HTML

Because there are different types of data formats which need to be sent over the internet, specifying the data type up front would allow the corresponding client to properly interpret and render the data accordingly to the user.

Why do we have different data formats?

Principally because they serve different purposes and have different abilities.

For example, a PDF format is very different from a picture format - which is also different from a sound format - both serve very different purposes and accordingly are written different prior to being sent over the internet.

The terminal uses environment variables to determine which character set to use, therefore you can determine it by looking at those variables:

echo $LC_CTYPE

or

echo $LANG

Another approach suitable for overriding a few properties in your test, if you are using @SpringBootTest annotation:

@SpringBootTest(properties = {"propA=valueA", "propB=valueB"})

JSONObject root= new JSONObject();
JSONObject container= root.getJSONObject("LabelData");

try{
//if key will not be available put it in the try catch block your program 
 will work without error 
String Video=container.getString("video");
}
catch(JsonException e){

 if key will not be there then this block will execute

 } 
 if(video!=null || !video.isEmpty){
  //get Value of video
}else{
  //other vise leave it
 }

i think this might help you

You can use Length annotation for a column. By using it you can maximize or minimize column length. Length annotation only be used for Strings.

@Column(name = "NAME", nullable = false, length = 50)  
@Length(max = 50)
public String getName() {
    return this.name;
}

You can use 'required' http://jsbin.com/atefuq/1/edit

<form action="login.php" method="post">
    <label>Login Name:</label>
    <input required type="text" name="email" id="log" />
    <label>Password:</label>
    <input required type="password" name="password" id="pwd" />
    <input  required type="submit" name="submit" value="Login" />
</form>

Try the change event and selected selector

$('#jobSel').change(function(){
    var optId = $(this).find('option:selected').attr('id')
})

Connect your javascript clientside controller and php serverside controller using sending and receiving opcodes with binded data. So your php code can send as response functional delta for js recepient/listener

Set the appended div to be hidden initially through css visibility:hidden.

I had the same problem, and the accepted answer didn't help me because the password wasn't stored in the keychain. I typed:

git pull https://[email protected]/mypath/myrepo.git

Then console asked me for my new password.

I used withStyles instead of makeStyle

EX :

import { withStyles } from '@material-ui/core/styles';
import React, {Component} from "react";

const useStyles = theme => ({
        root: {
           flexGrow: 1,
         },
  });

class App extends Component {
       render() {
                const { classes } = this.props;
                return(
                    <div className={classes.root}>
                       Test
                </div>
                )
          }
} 

export default withStyles(useStyles)(App)

as noted by @tripleee, this is tangential, at best.

still, in case you arrived here searching for something like that (as i did), here is my solution

having to deal with user acessible configuration files, i use this function :

function isTrue() {
    if [[ "${@^^}" =~ ^(TRUE|OUI|Y|O$|ON$|[1-9]) ]]; then return 0;fi
    return 1
    }

wich can be used like that

if isTrue "$whatever"; then..

You can alter the "truth list" in the regexp, the one in this sample is french compatible and considers strings like "Yeah, yup, on,1, Oui,y,true to be "True".

note that the '^^' provides case insensivity

I usually prefer to work with deltas in translate animation, since it avoids a lot of confusion.

Try this out, see if it works for you:

TranslateAnimation anim = new TranslateAnimation(0, amountToMoveRight, 0, amountToMoveDown);
anim.setDuration(1000);

anim.setAnimationListener(new TranslateAnimation.AnimationListener() {

    @Override
    public void onAnimationStart(Animation animation) { }

    @Override
    public void onAnimationRepeat(Animation animation) { }

    @Override
    public void onAnimationEnd(Animation animation) 
    {
        FrameLayout.LayoutParams params = (FrameLayout.LayoutParams)view.getLayoutParams();
        params.topMargin += amountToMoveDown;
        params.leftMargin += amountToMoveRight;
        view.setLayoutParams(params);
    }
});

view.startAnimation(anim);

Make sure to make amountToMoveRight / amountToMoveDown final

Hope this helps :)

The property file task is for editing properties files. It contains all sorts of nice features that allow you to modify entries. For example:

<propertyfile file="build.properties">
    <entry key="build_number"
        type="int"
        operation="+"
        value="1"/>
</propertyfile>

I've incremented my build_number by one. I have no idea what the value was, but it's now one greater than what it was before.

• Use the <echo> task to build a property file instead of <propertyfile>. You can easily layout the content and then use <propertyfile> to edit that content later on.

Example:

<echo file="build.properties">
# Default Configuration
source.dir=1
dir.publish=1
# Source Configuration
dir.publish.html=1
</echo>

• Create separate properties files for each section. You're allowed a comment header for each type. Then, use to batch them together into one single file:

Example:

<propertyfile file="default.properties"
    comment="Default Configuration">
    <entry key="source.dir" value="1"/>
    <entry key="dir.publish" value="1"/>
<propertyfile>

<propertyfile file="source.properties"
    comment="Source Configuration">
    <entry key="dir.publish.html" value="1"/>
<propertyfile>
<concat destfile="build.properties">
    <fileset dir="${basedir}">
        <include name="default.properties"/>
        <include name="source.properties"/>
    </fileset>
</concat>

<delete>
    <fileset dir="${basedir}">
         <include name="default.properties"/>
        <include name="source.properties"/>
    </fileset>
</delete>      

Try this tag on the pages that use the ActiveX control:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE10">

Note: this has to be the very first element in the <head> section.

This command should do the trick (provided that you installed it using a dpkg-based packet manager):

aptitude purge ruby

$('#dlg').dialog({
    title: 'My Dialog',
    left: (parseInt(jQuery(window).width())-1200)/2,
    top:(parseInt(jQuery(window).height())-720)/2,
    width: 1200,
    height: 720,
    closed: false,
    cache: false,
    modal: true,
    toolbar:'#dlg-toolbar'
});

You need to use this function.

JSON.parse(yourJsonString);

And it will return the object / array that was contained within the string.

Just go to the SQL Server Management Studio -> Tools -> Options -> Designer; and Uncheck the option "prevent saving changes that require table re-creation".

$request->validate([
    'phone' => 'numeric|required',
    'body' => 'required',
]);

You can't define a default constructor because you are using C#.

Structs can have default constructors in .NET, though I don't know of any specific language that supports it.

try (UPDATE)

MemoryStream ms = new MemoryStream(byteArrayIn,0,byteArrayIn.Length);
ms.Position = 0; // this is important

This theme required awhile to find results and reasons:

using MaiaDB 5.4. via SuSE-LINUX tumblweed

1. some files in the appointed directory havn't been necessary in any direct relation with mariadb. I.e: I placed some hints, a text-file, some bakup-copys somewhere in the same appointed directory for mysql mariadb and this caused endless error-messages and blocking the server from starting. Mariadb appears to be very sensible and hostile with the presence of other files not beeing database files(comments,backups,experimantal files etc) .

2. using libreoffice as client then there already this generated much problems with the creation and working on a database and caused some crashes.The crashes eventually produced bad tables.

3. May be because of that or may be because of the presence of not yet deleted but unusable tables !! the mysql mariadb server crashed and didn't want to do it' job not even start.

Error message always same : "Table 'some.table' doesn't exist in engine"

But when it started then tables appeared as normal, but it was unpossible to work on them.

So what to do without a more precise Error Message ?? The unusable tables showed up with: "CHECK TABLE" or on the command line of the system with "mysqlcheck " So I deleted by filemanager or on the system-level as root or as allowed user all the questionable files and then problem was solved.

Proposal: the Error Message could be a bit more precisely for example: "corrupted tables" (which can be found by CHECK TABLE, but only if the server is running) or by mysqlcheck even whe server is not running - but here are other disturbing files like hints/bakups a.s.o not visible.

ANYWAY it helped a lot to have backup-copies of the original database-files on a backup volume. This helped to check out and test it again and again until solution was found.

Good luck all - Herbert

I did it this way:

var xlApp = new Excel.Application();
var xlWorkBook = xlApp.Workbooks.Add(System.Reflection.Missing.Value);
var xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.Item[1];
xlWorkSheet.Columns.AutoFit();

With this way, columns always fit to text width inside cells.

Hope it helps to someone!

Don't use NULL, C++ allows you to use the unadorned 0 instead:

previous = 0;
next = 0;

And, as at C++11, you generally shouldn't be using either NULL or 0 since it provides you with nullptr of type std::nullptr_t, which is better suited to the task.

The webpack config file (in webpack 2) allows you to export a promise chain, so long as the last step returns a webpack config object. See promise configuration docs. From there:

webpack now supports returning a Promise from the configuration file. This allows to do async processing in you configuration file.

You could create a simple recursive copy function that copies your file, and only after that triggers webpack. E.g.:

module.exports = function(){
    return copyTheFiles( inpath, outpath).then( result => {
        return { entry: "..." } // Etc etc
    } )
}

See String Formatting Operations:

%d is the format code for an integer. %f is the format code for a float.

%s prints the str() of an object (What you see when you print(object)).

%r prints the repr() of an object (What you see when you print(repr(object)).

For a float %s, %r and %f all display the same value, but that isn't the case for all objects. The other fields of a format specifier work differently as well:

>>> print('%10.2s' % 1.123) # print as string, truncate to 2 characters in a 10-place field.
        1.
>>> print('%10.2f' % 1.123) # print as float, round to 2 decimal places in a 10-place field.
      1.12

to do this in a loop, you can do:

display(HTML("".join([f"<a href='{url}'>{url}</a></br>" for url in urls])))

This essentially creates the html text in a loop, and then uses the display(HTML()) construct to display the whole string as HTML

Agree with redsquare however it is worth mentioning that if you have a two word property like text-align you would do this:

$("#message").css({ width: '30px', height: '10px', 'text-align': 'center'});

Attention: You need to specify -- key, and than --with-mysql-config=/usr/local/mysql/bin/mysql_config

In Bootstrap 4, the 15px margin the initial container has, cascades down to all rows and columns. So, something like this works for me...

@media (max-width: 576px) {
    .container-fluid {
        padding-left: 5px;
        padding-right: 5px;
    }

    .row {
        margin-left: -5px;
        margin-right: -5px;
    }
    .col, .col-1, .col-10, .col-11, .col-12, .col-2, .col-3, .col-4, .col-5, .col-6, .col-7, .col-8, .col-9, .col-auto, .col-lg, .col-lg-1, .col-lg-10, .col-lg-11, .col-lg-12, .col-lg-2, .col-lg-3, .col-lg-4, .col-lg-5, .col-lg-6, .col-lg-7, .col-lg-8, .col-lg-9, .col-lg-auto, .col-md, .col-md-1, .col-md-10, .col-md-11, .col-md-12, .col-md-2, .col-md-3, .col-md-4, .col-md-5, .col-md-6, .col-md-7, .col-md-8, .col-md-9, .col-md-auto, .col-sm, .col-sm-1, .col-sm-10, .col-sm-11, .col-sm-12, .col-sm-2, .col-sm-3, .col-sm-4, .col-sm-5, .col-sm-6, .col-sm-7, .col-sm-8, .col-sm-9, .col-sm-auto, .col-xl, .col-xl-1, .col-xl-10, .col-xl-11, .col-xl-12, .col-xl-2, .col-xl-3, .col-xl-4, .col-xl-5, .col-xl-6, .col-xl-7, .col-xl-8, .col-xl-9, .col-xl-auto {
        padding-left: 5px;

}

Non-matched part of the URL is exposed as a request attribute named HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE:

@RequestMapping("/{id}/**")
public void foo(@PathVariable("id") int id, HttpServletRequest request) {
    String restOfTheUrl = (String) request.getAttribute(
        HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
    ...
}

I had a case where I was entering text into a field after which the text would be removed automatically. Turned out it was due to some site functionality where you had to press the enter key after entering the text into the field. So, after sending your barcode text with sendKeys method, send 'enter' directly after it. Note that you will have to import the selenium Keys class. See my code below.

import org.openqa.selenium.Keys;

String barcode="0000000047166";
WebElement element_enter = driver.findElement(By.xpath("//*[@id='div-barcode']"));
element_enter.findElement(By.xpath("your xpath")).sendKeys(barcode);

element_enter.sendKeys(Keys.RETURN); // this will result in the return key being pressed upon the text field

I hope it helps..

From Documentation

When you're saying

make an array holding an index number (int) of an indeterminate number of entities

you're basically saying you're using "pointers", but one which is a array-wide local pointer instead of memory-wide pointer. Since you're conceptually already using "pointers" (i.e. id numbers that refers to an element in an array), why don't you just use regular pointers (i.e. id numbers that refers to an element in the biggest array: the whole memory).

Instead of your objects storing a resource id numbers, you can make them store a pointer instead. Basically the same thing, but much more efficient since we avoid turning "array + index" into a "pointer".

Pointers are not scary if you think of them as array index for the whole memory (which is what they actually are)

I'm hardly a caching expert, but Mark Nottingham is. Here are his caching docs. He also has excellent links in the References section.

Based on my reading of those docs, it looks like max-age=0 could allow the cache to send a cached response to requests that came in at the "same time" where "same time" means close enough together they look simultaneous to the cache, but no-cache would not.

PDF2SVG version 6.0 from PDFTron does a reasonable job. It produces OpenType (.otf) fonts by default. Use --preserve_fontnames to preserve "the font/font-family naming scheme as obtained from the source file."

PDF2SVG is a commercial product, but you can download a free demo executable (which includes watermarks on the SVG output but doesn't otherwise restrict usage). There may be other PDFTron products that also extract fonts, but I only recently discovered PDF2SVG myself.

I uninstalled mysql in Ubuntu 16.04 https://askubuntu.com/questions/172514/how-do-i-uninstall-mysql

I reinstalled mysql https://www.digitalocean.com/community/tutorials/how-to-install-mysql-on-ubuntu-16-04

This seemed to work.

The required SQL will be some like:-

SELECT * FROM cd
LEFT JOIN ab ON ab.sht = cd.sht
LEFT JOIN aa ON aa.sht = cd.sht
....

Hope it helps.

Update: You can now <Elem onClick={ proxy => proxy.stopPropagation() } />

Be careful if you are working on localhost ! If you store your cookie in js like this:

document.cookie = "key=value;domain=localhost"

It might not be accessible to your subdomain, like sub.localhost. In order to solve this issue you need to use Virtual Host. For exemple you can configure your virtual host with ServerName localhost.com then you will be able to store your cookie on your domain and subdomain like this:

document.cookie = "key=value;domain=localhost.com"

<button class="btn btn-primary btn-lg" data-backdrop="static" data-keyboard="false" data-target="#myModal" data-toggle="modal">

In SQL Server 2017 STRING_AGG is added:

SELECT t.name,STRING_AGG (c.name, ',') AS csv
FROM sys.tables t
JOIN sys.columns c on t.object_id = c.object_id
GROUP BY t.name
ORDER BY 1

Also, STRING_SPLIT is usefull for the opposite case and available in SQL Server 2016

Some other options:

<object type="application/pdf" data="filename.pdf" width="100%" height="100%">
</object>

<object type="application/pdf" data="#request.localhost#_includes/filename.pdf" 
        width="100%" height="100%">
  <param name="src" value="#request.localhost#_includes/filename.pdf">
</object>

Note for Windows users, the jars should be separated by ; and not :.

for example: javac -cp external_libs\lib1.jar;other\lib2.jar;

A little late but I believe some further clarification is given below.

You can iterate through a JSON array with a simple loop as well, like:

for(var i = 0; i < jsonArray.length; i++)
{
    console.log(jsonArray[i].attributename);
}

If you have a JSON object and you want to loop through all of its inner objects, then you first need to get all the keys in an array and loop through the keys to retrieve objects using the key names, like:

var keys = Object.keys(jsonObject);
for(var i = 0; i < keys.length; i++) 
{
    var key = keys[i];
    console.log(jsonObject.key.attributename);
}

Just use it...

Firstly include the unistd.h header file, #include<unistd.h>, and use this function for pausing your program execution for desired number of seconds:

sleep(x);

x can take any value in seconds.

If you want to pause the program for 5 seconds it is like this:

sleep(5);

It is correct and I use it frequently.

It is valid for C and C++.

As long as the script is after the img, then:

var youtubeimgsrc = document.getElementById("youtubeimg").src;

See getElementById in the DOM specification.

If the script is before the img, then of course the img doesn't exist yet, and that doesn't work. This is one reason why many people recommend putting scripts at the end of the body element.

Side note: It doesn't matter in your case because you've used an absolute URL, but if you used a relative URL in the attribute, like this:

<img id="foo" src="/images/example.png">

...the src reflected property will be the resolved URL — that is, the absolute URL that that turns into. So if that were on the page http://www.example.com, document.getElementById("foo").src would give you "http://www.example.com/images/example.png".

If you wanted the src attribute's content as is, without being resolved, you'd use getAttribute instead: document.getElementById("foo").getAttribute("src"). That would give you "/images/example.png" with my example above.

If you have an absolute URL, like the one in your question, it doesn't matter.

          private void button2_Click(object sender, EventArgs e)

                Dictionary<string, string> Data_Array = new Dictionary<string, string>();
                Data_Array.Add("XML_File", "Settings.xml");

            }

lines is a list of strings, re.findall doesn't work with that. try:

import re, sys

f = open('findallEX.txt', 'r')
lines = f.read()
match = re.findall('[A-Z]+', lines)
print match

One thing that jumps out is the operator * overload (returning 0 is a lot friendlier than segfaulting...). Another thing is it doesn't look compatible with storing an address at all. Which, compared to how it goes slinging void*'s and passing NULL results to normal pointers as sentinel values, would obviously reduce the "never forget, it might be a bomb" factor.

As additional to @Karthick Kumar answer from bootstrap docs

show is triggered at the start of an event

shown is triggered on the completion of an action

... so it should be:

$('.modal')
    .on('show.bs.modal', function (){
            $('body').css('overflow', 'hidden');
        })
    .on('hide.bs.modal', function (){
            // Also if you are using multiple modals (cascade) - additional check
            if ($('.modal.in').length == 1) {
                $('body').css('overflow', 'auto');
            }
        });

By far the most easiest and reliable way to run Spring Boot applications in production is with Docker. Use Docker Compose, Docker Swarm or Kubernetes if you need to use multiple connected services.

Here's a simple Dockerfile from the official Spring Boot Docker guide to get you started:

FROM frolvlad/alpine-oraclejdk8:slim
VOLUME /tmp
ADD YOUR-APP-NAME.jar app.jar
RUN sh -c 'touch /app.jar'
ENV JAVA_OPTS=""
ENTRYPOINT [ "sh", "-c", "java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar" ]

Here's a sample command line to run the container as a daemon:

docker run \
  -d --restart=always \
  -e "SPRING_PROFILES_ACTIVE=prod" \
  -p 8080:8080 \
  prefix/imagename

You can't avoid polling, there isn't any event for href change.

Using intervals is quite light anyways if you don't go overboard. Checking the href every 50ms or so will not have any significant effect on performance if you're worried about that.

All you have to do is to set your textview width.

android:layout_width="60dp"

you can change the width to your choice. Just type long sentence to check if it working like this

android:text="i want to be among world class software engineer"

Just use a different browser. Follow the steps given below to install Chrome extensions on your Android device.

Step 1: Open Google Play Store and download Yandex Browser. Install the browser on your phone.

Step 2: In the URL box of your new browser, open 'chrome.google.com/webstore’ by entering the same in the URL address.

Step 3: Look for the Chrome extension that you want and once you have it, tap on 'Add to Chrome.’

The added Chrome extension will now be automatically added to the Yandex browser.

For Pip 8.1.2 you can use pip download -r requ.txt to download packages to your local machine.

Any recommendation on how to fix this?

Several. You can use bind:

for (i = 0; i < j; i++) {
    asycronouseProcess(function (i) {
        alert(i);
    }.bind(null, i));
}

Or, if your browser supports let (it will be in the next ECMAScript version, however Firefox already supports it since a while) you could have:

for (i = 0; i < j; i++) {
    let k = i;
    asycronouseProcess(function() {
        alert(k);
    });
}

Or, you could do the job of bind manually (in case the browser doesn't support it, but I would say you can implement a shim in that case, it should be in the link above):

for (i = 0; i < j; i++) {
    asycronouseProcess(function(i) {
        return function () {
            alert(i)
        }
    }(i));
}

I usually prefer let when I can use it (e.g. for Firefox add-on); otherwise bind or a custom currying function (that doesn't need a context object).

Adding to sagiv's answer, we should create the parent component in such a way that it can consist all children components rather than returning the child components in the way you were trying to return.

Try to intentiate the parent component and pass the props inside it so that all children can use it like below

const NewComponent = NewHOC(Movie);

Here NewHOC is the parent component and all its child are going to use movie as props.

But any way, you guyd6 have solved a problem for new react developers as this might be a problem that can come too and here is where they can find the solution for that.

In my case I was using more than two variables, and this worked for me better:

cor(x = as.matrix(tbl), method = "pearson", use = "pairwise.complete.obs")

However:

If use has the value "pairwise.complete.obs" then the correlation or covariance between each pair of variables is computed using all complete pairs of observations on those variables. This can result in covariance or correlation matrices which are not positive semi-definite, as well as NA entries if there are no complete pairs for that pair of variables.

If you're using Bash you could also use one of the following commands:

printf '%(%Y%m%d%H%M%S)T'       # prints the current time
printf '%(%Y%m%d%H%M%S)T' -1    # same as above
printf '%(%Y%m%d%H%M%S)T' -2    # prints the time the shell was invoked

You can use the Option -v varname to store the result in $varname instead of printing it to stdout:

printf -v varname '%(%Y%m%d%H%M%S)T'

While the date command will always be executed in a subshell (i.e. in a separate process) printf is a builtin command and will therefore be faster.

1 - Go to window . 2 - Go to Perspective and click . 3 - Go to Reset Perspective. 4 - Then you will find Eclipse all reset option.

"Better" is subjective.

querySelector is the newer feature.

getElementById is better supported than querySelector.

querySelector is better supported than getElementsByClassName.

querySelector lets you find elements with rules that can't be expressed with getElementById and getElementsByClassName

You need to pick the appropriate tool for any given task.

(In the above, for querySelector read querySelector / querySelectorAll).

Swift 4:

As per:

https://developer.apple.com/documentation/foundation/nserror

if you don't want to define a custom exception, you could use a standard NSError object as follows:

import Foundation

do {
  throw NSError(domain: "my error domain", code: 42, userInfo: ["ui1":12, "ui2":"val2"] ) 
}
catch let error as NSError {
  print("Caught NSError: \(error.localizedDescription), \(error.domain), \(error.code)")
  let uis = error.userInfo 
  print("\tUser info:")
  for (key,value) in uis {
    print("\t\tkey=\(key), value=\(value)")
  }
}

Prints:

Caught NSError: The operation could not be completed, my error domain, 42
    User info:
        key=ui1, value=12
        key=ui2, value=val2

This allows you to provide a custom string (the error domain), plus a numeric code and a dictionary with all the additional data you need, of any type.

N.B.: this was tested on OS=Linux (Ubuntu 16.04 LTS).

I know this is an old thread, but none of the answers really did it for me - either inefficient, or not encapsulated for easy reuse. I also wanted to ensure it returned false if the string was empty or null. TryParse returns true in this case (an empty string does not cause an error when parsing as a number). So, here's my string extension method:

public static class Extensions
{
    /// <summary>
    /// Returns true if string is numeric and not empty or null or whitespace.
    /// Determines if string is numeric by parsing as Double
    /// </summary>
    /// <param name="str"></param>
    /// <param name="style">Optional style - defaults to NumberStyles.Number (leading and trailing whitespace, leading and trailing sign, decimal point and thousands separator) </param>
    /// <param name="culture">Optional CultureInfo - defaults to InvariantCulture</param>
    /// <returns></returns>
    public static bool IsNumeric(this string str, NumberStyles style = NumberStyles.Number,
        CultureInfo culture = null)
    {
        double num;
        if (culture == null) culture = CultureInfo.InvariantCulture;
        return Double.TryParse(str, style, culture, out num) && !String.IsNullOrWhiteSpace(str);
    }
}

Simple to use:

var mystring = "1234.56789";
var test = mystring.IsNumeric();

Or, if you want to test other types of number, you can specify the 'style'. So, to convert a number with an Exponent, you could use:

var mystring = "5.2453232E6";
var test = mystring.IsNumeric(style: NumberStyles.AllowExponent);

Or to test a potential Hex string, you could use:

var mystring = "0xF67AB2";
var test = mystring.IsNumeric(style: NumberStyles.HexNumber)

The optional 'culture' parameter can be used in much the same way.

It is limited by not being able to convert strings that are too big to be contained in a double, but that is a limited requirement and I think if you are working with numbers larger than this, then you'll probably need additional specialised number handling functions anyway.

Use either:

balancePanel.Left = optionsPanel.Location.X;

or

balancePanel.Location = new Point(optionsPanel.Location.X, balancePanel.Location.Y);

See the documentation of Location:

Because the Point class is a value type (Structure in Visual Basic, struct in Visual C#), it is returned by value, meaning accessing the property returns a copy of the upper-left point of the control. So, adjusting the X or Y properties of the Point returned from this property will not affect the Left, Right, Top, or Bottom property values of the control. To adjust these properties set each property value individually, or set the Location property with a new Point.

Your program should not write temporary files (or anything else for that matter) to the program directory. Any program should use %TEMP% for temporary files and %APPDATA% for user specific application data. This has been true since Windows 2000/XP so you should change your aplication.

The problem is not Windows 7.

You can ask for appdata folder path:

string dir = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);

or for TEMP path

string dir = Path.GetTempPath()

The simplest way to get tooltips in most browsers is to set some text in the title attribute.

eg.

<img src="myimage.jpg" alt="a cat" title="My cat sat on a table" />

produces (hover your mouse over the image):

a cat http://www.imagechicken.com/uploads/1275939952008633500.jpg

Title attributes can be applied to most HTML elements.

Angular 2.x && Angular 4.x do not support this out of the box

You can use this two pipes to iterate either by key or by value.

Keys pipe:

import {Pipe, PipeTransform} from '@angular/core'

@Pipe({
  name: 'keys',
  pure: false
})
export class KeysPipe implements PipeTransform {
  transform(value: any, args: any[] = null): any {
    return Object.keys(value)
  }
}

Values pipe:

import {Pipe, PipeTransform} from '@angular/core'

@Pipe({
  name: 'values',
  pure: false
})
export class ValuesPipe implements PipeTransform {
  transform(value: any, args: any[] = null): any {
    return Object.keys(value).map(key => value[key])
  }
}

How to use:

let data = {key1: 'value1', key2: 'value2'}

<div *ngFor="let key of data | keys"></div>
<div *ngFor="let value of data | values"></div>

I found python -m http.server unreliable—some responses would take seconds.

Now I use a server called Ran https://github.com/m3ng9i/ran

Ran: a simple static web server written in Go

Thread th = new Thread(function1);
th.Start();
th.Abort();

void function1(){
//code here
}

You were on the right track with response.getOutputStream(), but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:

@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
    // convert JSON to Employee 
    Employee emp = convertSomehow(json);

    // generate the file
    PdfUtil.showHelp(emp);

    // retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
    byte[] contents = (...);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_PDF);
    // Here you have to set the actual filename of your pdf
    String filename = "output.pdf";
    headers.setContentDispositionFormData(filename, filename);
    headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
    ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
    return response;
}

Notes:

• use meaningful names for your methods: naming a method that writes a PDF document showHelp is not a good idea
• reading a file into a byte[]: example here
• I'd suggest adding a random string to the temporary PDF file name inside showHelp() to avoid overwriting the file if two users send a request at the same time

Because one moderator deleted my detailed image-supported answer on this question, just because I copied and pasted from another question, I am forced to put a less detailed answer and I will link the original answer if you want a more visual way to see the solution.

For Visual Studio 2019 and Visual Studio 2017 Users
For People who are missing this old feature in VS2019 (or maybe VS2017) from the old versions of Visual Studio

This feature still available, but it is NOT available by default, you have to install it separately.

1. Open VS 2019 go to Tools -> Get Tools and Features
2. Select the Individual components tab and search for Class Designer
3. Select this Component and Install it, After finish installing this component (you may need to restart visual studio)
4. Right-click on the project and select Add -> Add New Item
5. Search for 'class' word and NOW you can see Class Diagram component

Update to create a class-diagram for the whole project
I received a downvote because I did not mention how to generate a diagram for the whole project, here is how to do it (after applying the previous steps)

1. Add class diagram to the project
2. if the option Preview Selected Items is enabled in the solution explorer, disabled it temporarily, you can re-enable it later

3. open the class diagram that you created in step 2 (by double-clicking on it)
4. drag-and-drop the project from the solution explorer to the class diagram

you could be shocked by the results to the point that you can change your mind and remove your downvote (please do NOT upvote, it is enough to remove your downvote)

If you have error INSTALL_FAIL_DEXOPT, see in manifest android:targetSdkVersion. Set version < 21 sample:

This worked for me.

string URI = "site.com/mail.php";
using (WebClient client = new WebClient())
{
    System.Collections.Specialized.NameValueCollection postData =

       {
              { "to", emailTo },

       };
    string pagesource = Encoding.UTF8.GetString(client.UploadValues(URI, postData));
}

These are all too long.

Just use:

new Date(System.currentTimeMillis())

The closest thing to what you're looking for is the :first-child pseudoclass; unfortunately this will not work in your case because you have an <h1> before the <div>s. What I would suggest is that you either add a class to the <div>, like <div class="first"> and then style it that way, or use jQuery if you really can't add a class:

$('#content > div:first')

use <br/> tag

Example:

<string name="copyright"><b>@</b> 2014 <br/>
Corporation.<br/>
<i>All rights reserved.</i></string>

Here are a few ways of removing a single ' from a string in python.

• str.replace

  replace is usually used to return a string with all the instances of the substring replaced.

  "A single ' char".replace("'","")
  

• str.translate

  In Python 2

  To remove characters you can pass the first argument to the funstion with all the substrings to be removed as second.

  "A single ' char".translate(None,"'")
  

  In Python 3

  You will have to use str.maketrans

  "A single ' char".translate(str.maketrans({"'":None}))
  

• re.sub

  Regular Expressions using re are even more powerful (but slow) and can be used to replace characters that match a particular regex rather than a substring.

  re.sub("'","","A single ' char")
  

Other Ways

There are a few other ways that can be used but are not at all recommended. (Just to learn new ways). Here we have the given string as a variable string.

• Using list comprehension

  ''.join([c for c in string if c != "'"])
  

• Using generator Expression

  ''.join(c for c in string if c != "'")
  

Another final method can be used also (Again not recommended - works only if there is only one occurrence )

• Using list call along with remove and join.

  x = list(string)
  x.remove("'")
  ''.join(x)
  

You can use case in update and SWAP as many as you want

update Table SET column=(case when is_row_1 then value_2 else value_1 end) where rule_to_match_swap_columns

I used this method.

Looper.myLooper().quit();

you can try.

In Swift 4.0.3 Xcode 9

============set  Data in UserDefaults =========

  UserDefaults.standard.set(userName, forKey: "userName")
  UserDefaults.standard.synchronize()

============Get Data in UserDefaults =========

  let userName = UserDefaults.standard.string(forKey: "userName")
  print(userName ?? "Gera")

  userNameTextField.text = ""+userName!

try this:

result = $("#result", response);

btw alert is a rough way to debug things, try console.log

If your compiler supports Variadic macros (which is true for most modern compilers), then you can use the following macro to turn vector initialization into a one-liner:

#define INIT_VECTOR(type, name, ...) \
static const type name##_a[] = __VA_ARGS__; \
vector<type> name(name##_a, name##_a + sizeof(name##_a) / sizeof(*name##_a))

With this macro, you can define an initialized vector with code like this:

INIT_VECTOR(int, my_vector, {1, 2, 3, 4});

This would create a new vector of ints named my_vector with the elements 1, 2, 3, 4.

You can cast this value to a Boolean in a very simple manner: by comparing it with integer value 1, like this:

boolean multipleContacts = new Integer(1).equals(jsonObject.get("MultipleContacts"))

If it is a String, you could do this:

boolean multipleContacts = "1".equals(jsonObject.get("MultipleContacts"))

Mostafa has already pointed out that such a method is trivial to write, and mkb gave you a hint to use the binary search from the sort package. But if you are going to do a lot of such contains checks, you might also consider using a map instead.

It's trivial to check if a specific map key exists by using the value, ok := yourmap[key] idiom. Since you aren't interested in the value, you might also create a map[string]struct{} for example. Using an empty struct{} here has the advantage that it doesn't require any additional space and Go's internal map type is optimized for that kind of values. Therefore, map[string] struct{} is a popular choice for sets in the Go world.

Following are three different approaches

1. Enum

    /**
    * Singleton pattern example using Java Enum
    */
    public enum EasySingleton {
        INSTANCE;
    }
   

2. Double checked locking / lazy loading

    /**
    * Singleton pattern example with Double checked Locking
    */
    public class DoubleCheckedLockingSingleton {
         private static volatile DoubleCheckedLockingSingleton INSTANCE;
   
         private DoubleCheckedLockingSingleton() {}
   
         public static DoubleCheckedLockingSingleton getInstance() {
             if(INSTANCE == null) {
                synchronized(DoubleCheckedLockingSingleton.class) {
                    // Double checking Singleton instance
                    if(INSTANCE == null) {
                        INSTANCE = new DoubleCheckedLockingSingleton();
                    }
                }
             }
             return INSTANCE;
         }
    }
   

3. Static factory method

    /**
    * Singleton pattern example with static factory method
    */
   
    public class Singleton {
        // Initialized during class loading
        private static final Singleton INSTANCE = new Singleton();
   
        // To prevent creating another instance of 'Singleton'
        private Singleton() {}
   
        public static Singleton getSingleton() {
            return INSTANCE;
        }
    }
   

If you don't want do 'new myPipe()' because you're injecting dependencies to pipe, you can inject in component like provider and use without new.

Example:

    // In your component...

    import { Component, OnInit } from '@angular/core';
    import { myPipe} from './pipes';

    @Component({
      selector: 'my-component',
      template: '{{ data }}',
      providers: [ myPipe ]
    })
    export class MyComponent() implements OnInit {
      data = 'some data';
      constructor(private myPipe: myPipe) {}

      ngOnInit() {
        this.data = this.myPipe.transform(this.data);
      }
    }

It's shorthand for tags.map(&:name.to_proc).join(' ')

If foo is an object with a to_proc method, then you can pass it to a method as &foo, which will call foo.to_proc and use that as the method's block.

The Symbol#to_proc method was originally added by ActiveSupport but has been integrated into Ruby 1.8.7. This is its implementation:

class Symbol
  def to_proc
    Proc.new do |obj, *args|
      obj.send self, *args
    end
  end
end

The assert statement exists in almost every programming language. It helps detect problems early in your program, where the cause is clear, rather than later as a side-effect of some other operation. They always expect a True condition.

When you do something like:

assert condition

You're telling the program to test that condition and immediately trigger an error if it is false.

In Python, assert expression, is equivalent to:

if __debug__:
    if not <expression>: raise AssertionError

You can use the extended expression to pass an optional message:

if __debug__:
    if not (expression_1): raise AssertionError(expression_2)

Try it in the Python interpreter:

>>> assert True # Nothing happens because the condition returns a True value.
>>> assert False # A traceback is triggered because this evaluation did not yield an expected value.
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AssertionError

There are some caveats to seen before using them mainly for those who deem to toggles between the assert and if statements. The aim to use assert is on occasions when the program verifies a condition and return a value that should stop the program immediately instead of taking some alternative way to bypass the error:

1. Parentheses

As you may have noticed, the assert statement uses two conditions. Hence, do not use parentheses to englobe them as one for obvious advice. If you do such as:

assert (condition, message)

Example:

>>> assert (1==2, 1==1)
<stdin>:1: SyntaxWarning: assertion is always true, perhaps remove parentheses?

You will be running the assert with a (condition, message) which represents a tuple as the first parameter, and this happens cause non-empty tuple in Python is always True. However, you can do separately without problem:

assert (condition), "message"

Example:

>>> assert (1==2), ("This condition returns a %s value.") % "False"
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AssertionError: This condition returns a False value.

2. Debug purpose

If you are wondering regarding when use assert statement. Take an example used in real life:

* When your program tends to control each parameter entered by the user or whatever else:

def loremipsum(**kwargs):
    kwargs.pop('bar') # return 0 if "bar" isn't in parameter
    kwargs.setdefault('foo', type(self)) # returns `type(self)` value by default
    assert (len(kwargs) == 0), "unrecognized parameter passed in %s" % ', '.join(kwargs.keys())

* Another case is on math when 0 or non-positive as a coefficient or constant on a certain equation:

def discount(item, percent):
    price = int(item['price'] * (1.0 - percent))
    print(price)
    assert (0 <= price <= item['price']),\
            "Discounted prices cannot be lower than 0 "\
            "and they cannot be higher than the original price."

    return price

* or even a simple example of a boolean implementation:

def true(a, b):
    assert (a == b), "False"
    return 1

def false(a, b):
    assert (a != b), "True"
    return 0

3. Data processing or data validation

The utmost importance is to not rely on the assert statement to execute data processing or data validation because this statement can be turned off on the Python initialization with -O or -OO flag – meaning value 1, 2, and 0 (as default), respectively – or PYTHONOPTIMIZE environment variable.

Value 1:

* asserts are disabled;

* bytecode files are generated using .pyo extension instead of .pyc;

* sys.flags.optimize is set to 1 (True);

* and, __debug__ is set to False;

Value 2: disables one more stuff

* docstrings are disabled;

Therefore, using the assert statement to validate a sort of expected data is extremely dangerous, implying even to some security issues. Then, if you need to validate some permission I recommend you raise AuthError instead. As a preconditional effective, an assert is commonly used by programmers on libraries or modules that do not have a user interact directly.

Logically there are no difference at all. Performance-wise there are -typically, on most DBMSes- no difference at all.

A slightly lighter task that doesn't unnecessarily copy files to a dir:

task downloadDependencies(type: Exec) {
    configurations.testRuntime.files
    commandLine 'echo', 'Downloaded all dependencies'
}

Updated for kotlin & gradle 6.2.0, with buildscript dependency resolution added:

fun Configuration.isDeprecated() = this is DeprecatableConfiguration && resolutionAlternatives != null

fun ConfigurationContainer.resolveAll() = this
  .filter { it.isCanBeResolved && !it.isDeprecated() }
  .forEach { it.resolve() }

tasks.register("downloadDependencies") {
  doLast {
    configurations.resolveAll()
    buildscript.configurations.resolveAll()
  }
}

It is happening because .header-shadow is empty.

Add height to it:

.header-shadow{
    background-image: url('../images/header-shade.jpg');
    background-color: red;
    height: 50px;
}

Fiddle here.

Try this

std::string s(reinterpret_cast<const char *>(Data), Size);

CREATE TABLE db1.table1 SELECT * FROM db2.table1

where db1 is the destination and db2 is the source

You may want to also look into using Task instead of background workers.

The easiest way to do this is in your example is Task.Run(InitializationThread);.

There are several benefits to using tasks instead of background workers. For example, the new async/await features in .net 4.5 use Task for threading. Here is some documentation about Task https://docs.microsoft.com/en-us/dotnet/api/system.threading.tasks.task

Here is a simple code:

ConfigurableListableBeanFactory beanFactory = ((ConfigurableApplicationContext) applicationContext).getBeanFactory();
beanFactory.registerSingleton(bean.getClass().getCanonicalName(), bean);

   .search-table-outter {border:2px solid red; overflow-x:scroll;}
   .search-table{table-layout: fixed; margin:40px auto 0px auto;   }
   .search-table, td, th{border-collapse:collapse; border:1px solid #777;}
   th{padding:20px 7px; font-size:15px; color:#444; background:#66C2E0;}
   td{padding:5px 10px; height:35px;}

You should provide scroll in div.

As I found best and suitable option for me and it will work with animation too.

You can use indicator it self as a background.

You can set app:tabIndicatorGravity="stretch" attribute to use as background.

Example:

   <android.support.design.widget.TabLayout
        android:id="@+id/tab_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabIndicatorGravity="stretch"
        app:tabSelectedTextColor="@color/white"
        app:tabTextColor="@color/colorAccent">

        <android.support.design.widget.TabItem
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Chef" />


        <android.support.design.widget.TabItem
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="User" />

    </android.support.design.widget.TabLayout>

Hope it will helps you.

Try the solution below, it's O(n) and it will store and return the second greatest number in the second variable. UPDATE: I've adjusted the code to work with Python 3, because now arithmetic comparisons against None are invalid.

Notice that if all elements in numbers are equal, or if numbers is empty or if it contains a single element, the variable second will end up with a value of None - this is correct, as in those cases there isn't a "second greatest" element.

Beware: this finds the "second maximum" value, if there's more than one value that is "first maximum", they will all be treated as the same maximum - in my definition, in a list such as this: [10, 7, 10] the correct answer is 7.

def second_largest(numbers):
    minimum = float('-inf')
    first, second = minimum, minimum
    for n in numbers:
        if n > first:
            first, second = n, first
        elif first > n > second:
            second = n
    return second if second != minimum else None

Here are some tests:

second_largest([20, 67, 3, 2.6, 7, 74, 2.8, 90.8, 52.8, 4, 3, 2, 5, 7])
=> 74
second_largest([1, 1, 1, 1, 1, 2])
=> 1
second_largest([2, 2, 2, 2, 2, 1])
=> 1
second_largest([10, 7, 10])
=> 7
second_largest( [1, 3, 10, 16])
=> 10
second_largest([1, 1, 1, 1, 1, 1])
=> None
second_largest([1])
=> None
second_largest([])
=> None

Two ways that work:

1. Use stringBuilderObj.setLength(0).
2. Allocate a new one with new StringBuilder() instead of clearing the buffer.

You could also use a LEFT JOIN and IS NULL condition:

SELECT 
  mac, 
  creation_date 
FROM 
  logs
    LEFT JOIN consols ON logs.mac = consols.mac
WHERE 
  logs_type_id=11
AND
  consols.mac IS NULL;

An index on the "mac" columns might improve performance.

I have programmed a module wich is able to hash big files with different algorithms.

pip3 install py_essentials

Use the module like this:

from py_essentials import hashing as hs
hash = hs.fileChecksum("path/to/the/file.txt", "sha256")

I had the same problem, so I wrote this. It works rather well. Looks great if you mix it with some CSS transitions.

function toggle_visibility(id) {
   var e = document.getElementById("mjwelcome");
   if(e.style.height == '')
      e.style.height = '0px';
   else
      e.style.height = '';
}

Found the answer here: http://www.digitallycreated.net/Blog/59/locally-publishing-a-vs2010-asp.net-web-application-using-msbuild

Visual Studio 2010 has great new Web Application Project publishing features that allow you to easy publish your web app project with a click of a button. Behind the scenes the Web.config transformation and package building is done by a massive MSBuild script that’s imported into your project file (found at: C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\Web\Microsoft.Web.Publishing.targets). Unfortunately, the script is hugely complicated, messy and undocumented (other then some oft-badly spelled and mostly useless comments in the file). A big flowchart of that file and some documentation about how to hook into it would be nice, but seems to be sadly lacking (or at least I can’t find it).

Unfortunately, this means performing publishing via the command line is much more opaque than it needs to be. I was surprised by the lack of documentation in this area, because these days many shops use a continuous integration server and some even do automated deployment (which the VS2010 publishing features could help a lot with), so I would have thought that enabling this (easily!) would be have been a fairly main requirement for the feature.

Anyway, after digging through the Microsoft.Web.Publishing.targets file for hours and banging my head against the trial and error wall, I’ve managed to figure out how Visual Studio seems to perform its magic one click “Publish to File System” and “Build Deployment Package” features. I’ll be getting into a bit of MSBuild scripting, so if you’re not familiar with MSBuild I suggest you check out this crash course MSDN page.

Publish to File System

The VS2010 Publish To File System Dialog Publish to File System took me a while to nut out because I expected some sensible use of MSBuild to be occurring. Instead, VS2010 does something quite weird: it calls on MSBuild to perform a sort of half-deploy that prepares the web app’s files in your project’s obj folder, then it seems to do a manual copy of those files (ie. outside of MSBuild) into your target publish folder. This is really whack behaviour because MSBuild is designed to copy files around (and other build-related things), so it’d make sense if the whole process was just one MSBuild target that VS2010 called on, not a target then a manual copy.

This means that doing this via MSBuild on the command-line isn’t as simple as invoking your project file with a particular target and setting some properties. You’ll need to do what VS2010 ought to have done: create a target yourself that performs the half-deploy then copies the results to the target folder. To edit your project file, right click on the project in VS2010 and click Unload Project, then right click again and click Edit. Scroll down until you find the Import element that imports the web application targets (Microsoft.WebApplication.targets; this file itself imports the Microsoft.Web.Publishing.targets file mentioned earlier). Underneath this line we’ll add our new target, called PublishToFileSystem:

<Target Name="PublishToFileSystem"
        DependsOnTargets="PipelinePreDeployCopyAllFilesToOneFolder">
    <Error Condition="'$(PublishDestination)'==''"
           Text="The PublishDestination property must be set to the intended publishing destination." />
    <MakeDir Condition="!Exists($(PublishDestination))"
             Directories="$(PublishDestination)" />

    <ItemGroup>
        <PublishFiles Include="$(_PackageTempDir)\**\*.*" />
    </ItemGroup>

    <Copy SourceFiles="@(PublishFiles)"
          DestinationFiles="@(PublishFiles->'$(PublishDestination)\%(RecursiveDir)%(Filename)%(Extension)')"
          SkipUnchangedFiles="True" />
</Target>

This target depends on the PipelinePreDeployCopyAllFilesToOneFolder target, which is what VS2010 calls before it does its manual copy. Some digging around in Microsoft.Web.Publishing.targets shows that calling this target causes the project files to be placed into the directory specified by the property _PackageTempDir.

The first task we call in our target is the Error task, upon which we’ve placed a condition that ensures that the task only happens if the PublishDestination property hasn’t been set. This will catch you and error out the build in case you’ve forgotten to specify the PublishDestination property. We then call the MakeDir task to create that PublishDestination directory if it doesn’t already exist.

We then define an Item called PublishFiles that represents all the files found under the _PackageTempDir folder. The Copy task is then called which copies all those files to the Publish Destination folder. The DestinationFiles attribute on the Copy element is a bit complex; it performs a transform of the items and converts their paths to new paths rooted at the PublishDestination folder (check out Well-Known Item Metadata to see what those %()s mean).

To call this target from the command-line we can now simply perform this command (obviously changing the project file name and properties to suit you):

msbuild Website.csproj "/p:Platform=AnyCPU;Configuration=Release;PublishDestination=F:\Temp\Publish" /t:PublishToFileSystem

Code based on the following pull request:

datapoint.color = 'hsl(' + (360 * index / data.length) + ', 100%, 50%)';

You can do something like this

import React from 'react';

class Header extends React.Component {

constructor() {
    super();
}

checkClick(e, notyId) {
    alert(notyId);
}

render() {
    return (
        <PopupOver func ={this.checkClick } />
    )
}
};

class PopupOver extends React.Component {

constructor(props) {
    super(props);
    this.props.func(this, 1234);
}

render() {
    return (
        <div className="displayinline col-md-12 ">
            Hello
        </div>
    );
}
}

export default Header;

Using statics

var MyComponent = React.createClass({
 statics: {
 customMethod: function(foo) {
  return foo === 'bar';
  }
 },
   render: function() {
 }
});

MyComponent.customMethod('bar');  // true

The SQL Query select * from openjson ... works only with SQL version 2016 and higher. Need the SQL compatibility mode 130.

First, you declared $db outside the function. If you want to use it inside the function, you should put this at the begining of your function code:

global $db;

And I guess, when you wrote:

if($result->num_rows){
        return (mysqli_result($query, 0) == 1) ? true : false;

what you really wanted was:

if ($result->num_rows==1) { return true; } else { return false; }

My solution for this problem is to set a Mutation Observer to detect <script></script> nodes and then replace it with a new <script></script> node with the same src. For example:

let parentNode = /* node to observe */ void 0
let observer = new MutationObserver(mutations=>{
    mutations.map(mutation=>{
        Array.from(mutation.addedNodes).map(node=>{
            if ( node.parentNode == parentNode ) {
                let scripts = node.getElementsByTagName('script')
                Array.from(scripts).map(script=>{
                    let src = script.src
                    script = document.createElement('script')
                    script.src = src
                    return script
                })
            }
        })
    })
})
observer.observe(document.body, {childList: true, subtree: true});

use following code

function numericFilter(txb) {
   txb.value = txb.value.replace(/[^\0-9]/ig, "");
}

call it in on key up

<input type="text" onKeyUp="numericFilter(this);" />

Naive question: Is it possible to somehow download GLIBC 2.15, put it in any folder (e.g. /tmp/myglibc) and then point to this path ONLY when executing something that needs this specific version of glibc?

Yes, it's possible.

Select 'YOU WILL SEE ME' as ANSWER from dual
where exists (select 1 from dual where 1 = 1);

Select 'YOU CAN NOT SEE ME' as ANSWER from dual
where exists (select 1 from dual where 1 = 0);

Select 'YOU WILL SEE ME, TOO' as ANSWER from dual
where not exists (select 1 from dual where 1 = 0);

Looking at it from a practical rather than theoretical standpoint, on a 32 bit Windows system, the maximum total amount of memory available for a single process is 2 GB. You can break the limit by going to a 64 bit operating system with much more physical memory, but whether to do this or look for alternatives depends very much on your intended users and their budgets. You can also extend it somewhat using PAE.

The type of the array is very important, as default structure alignment on many compilers is 8 bytes, which is very wasteful if memory usage is an issue. If you are using Visual C++ to target Windows, check out the #pragma pack directive as a way of overcoming this.

Another thing to do is look at what in memory compression techniques might help you, such as sparse matrices, on the fly compression, etc... Again this is highly application dependent. If you edit your post to give some more information as to what is actually in your arrays, you might get more useful answers.

Edit: Given a bit more information on your exact requirements, your storage needs appear to be between 7.6 GB and 76 GB uncompressed, which would require a rather expensive 64 bit box to store as an array in memory in C++. It raises the question why do you want to store the data in memory, where one presumes for speed of access, and to allow random access. The best way to store this data outside of an array is pretty much based on how you want to access it. If you need to access array members randomly, for most applications there tend to be ways of grouping clumps of data that tend to get accessed at the same time. For example, in large GIS and spatial databases, data often gets tiled by geographic area. In C++ programming terms you can override the [] array operator to fetch portions of your data from external storage as required.

It's an automatically backed property, basically equivalent to:

private string type;
public string Type
{
   get{ return type; }
   set{ type = value; }
}

Oracles Java Tutorial for File Choosers: http://docs.oracle.com/javase/tutorial/uiswing/components/filechooser.html

Note getSelectedFile() returns the selected folder, despite the name. getCurrentDirectory() returns the directory of the selected folder.

import javax.swing.*;

public class Example
{
    public static void main(String[] args)
    {
        JFileChooser f = new JFileChooser();
        f.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY); 
        f.showSaveDialog(null);

        System.out.println(f.getCurrentDirectory());
        System.out.println(f.getSelectedFile());
    }      
}

Is more simple without using scp:

tar cf - file1 ... file_n | ssh user@server 'tar xf -'

This also let you do some things like compress the stream (-C) or (since OpenSSH v7.3) -J any times to jump through one (or more) proxy servers.

You can avoid using passwords coping your public key to ~/.ssh/authorized_keys with ssh-copy-id.

Posted also here (with more details) and here.

You can use the Task Parallel Library. To be more exact, you can use Task.Wait(TimeSpan):

using System.Threading.Tasks;

var task = Task.Run(() => SomeMethod(input));
if (task.Wait(TimeSpan.FromSeconds(10)))
    return task.Result;
else
    throw new Exception("Timed out");

This is caused by non-matching Spring Boot dependencies. Check your classpath to find the offending resources. You have explicitly included version 1.1.8.RELEASE, but you have also included 3 other projects. Those likely contain different Spring Boot versions, leading to this error.

Use this:

return JavaScript(alert("Hello this is an alert"));

or:

return Content("<script language='javascript' type='text/javascript'>alert('Thanks for Feedback!');</script>");

No, you cannot set the border height.

Pasted below:

This is about how to launch android application from the adb shell.

Command: am

Look for invoking path in AndroidManifest.xml

Browser app::

# am start -a android.intent.action.MAIN -n com.android.browser/.BrowserActivity
Starting: Intent { action=android.intent.action.MAIN comp={com.android.browser/com.android.browser.BrowserActivity} }
Warning: Activity not started, its current task has been brought to the front

Settings app::

# am start -a android.intent.action.MAIN -n com.android.settings/.Settings
Starting: Intent { action=android.intent.action.MAIN comp={com.android.settings/com.android.settings.Settings} }

If you have an html form containing one or more fields with "required" attributes, Chrome (on last versions) will validate these fields before submitting the form and, if they are not filled, some tooltips will be shown to the users to help them getting the form submitted (I.e. "please fill out this field").

To avoid this browser built-in validation in forms you can use "novalidate" attribute on your form tag. This form won't be validated by browser:

<form id="form-id" novalidate>

    <input id="input-id" type="text" required>

    <input id="submit-button" type="submit">

</form>

unset is the command you're looking for.

unset GNUPLOT_DRIVER_DIR

I got a solution!

When resetting root password at step 2), also change the auth plugin to mysql_native_password:

use mysql;
update user set authentication_string=PASSWORD("") where User='root';
update user set plugin="mysql_native_password" where User='root';  # THIS LINE

flush privileges;
quit;

This allowed me to log in successfully!

Full code solution

1. run bash commands

1. first, run these bash commands

sudo /etc/init.d/mysql stop # stop mysql service
sudo mysqld_safe --skip-grant-tables & # start mysql without password
# enter -> go
mysql -uroot # connect to mysql

2. then run mysql commands => copy paste this to cli manually

use mysql; # use mysql table
update user set authentication_string=PASSWORD("") where User='root'; # update password to nothing
update user set plugin="mysql_native_password" where User='root'; # set password resolving to default mechanism for root user

flush privileges;
quit;

3. run more bash commands

sudo /etc/init.d/mysql stop 
sudo /etc/init.d/mysql start # reset mysql
# try login to database, just press enter at password prompt because your password is now blank
mysql -u root -p 

4. Socket issue (from your comments)

When you see a socket error, a community came with 2 possible solutions:

sudo mkdir -p /var/run/mysqld; sudo chown mysql /var/run/mysqld
sudo mysqld_safe --skip-grant-tables &

(thanks to @Cerin)

Or

mkdir -p /var/run/mysqld && chown mysql:mysql /var/run/mysqld  

(thanks to @Peter Dvukhrechensky)

Blind paths and possible edge errors

Use 127.0.0.1 instead of localhost

mysql -uroot # "-hlocalhost" is default

Can lead to "missing file" or slt error.

mysql -uroot -h127.0.0.1

Works better.

Skip the socket issue

I've found many ways to create mysqld.sock file, change access rights or symlink it. It was not the issue after all.

Skip the my.cnf file

The issue also was not there. If you are not sure, this might help you.

Do you want the digits sorted? Or are you swapping odd/even indexed digits? Your example is totally unclear.

Sort:

s = '2143'
p=list(s)
p.sort()
s = "".join(p)

s is now '1234'. The trick is here that list(string) breaks it into characters.

again this is all in the link you supplied

to change the text to white all you have to do is change the theme.

use this theme

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/activity_my_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>

To open at a specific line straight from the command line, use:

less +320123 filename

If you want to see the line numbers too:

less +320123 -N filename

You can also choose to display a specific line of the file at a specific line of the terminal, for when you need a few lines of context. For example, this will open the file with line 320123 on the 10th line of the terminal:

less +320123 -j 10 filename

You may also use the stringr package

library(dplyr)
library(stringr)
My.Data %>% filter(str_detect(x, '^G45'))

You may not use '^' (starts with) in this case, to obtain the results you need

Nuts. I hit this same error weeks ago, and after a lot of wasted time figured out how to make it work--but I've since forgotten it. (Not much help, other than to say yes, it can be done.)

Have you tried different combinations of brackets, or of with and without brackest? e.g.

EXEC sp_rename 'ENG_TEst.ENG_Test_A/C_TYPE', 'ENG_Test_AC_TYPE', 'COLUMN';
EXEC sp_rename '[ENG_TEst].[ENG_Test_A/C_TYPE]', 'ENG_Test_AC_TYPE', 'COLUMN';
EXEC sp_rename '[ENG_TEst].[ENG_Test_A/C_TYPE]', '[ENG_Test_AC_TYPE]', 'COLUMN';
EXEC sp_rename '[ENG_TEst].ENG_Test_A/C_TYPE', 'ENG_Test_AC_TYPE', 'COLUMN';

If all else fails, there's always

• Create new table (as "xENG_TEst") with proper names
• Copy data over from old table
• Drop old table
• Rename new table to final name

You can do this in QtDesigner. Just click on your button then go to icon property and then choose your image file.

I use Butterknife with switch-case to handle this kind of cases:

    @OnClick({R.id.button_bireysel, R.id.button_kurumsal})
        public void onViewClicked(View view) {
            switch (view.getId()) {


                case R.id.button_bireysel:
 //Do something

                    break;
                case R.id.button_kurumsal:

     //Do something

                    break;

            }
        }

But the thing is there is no default case and switch statement falls through

You have to properly understand what is a "stdafx.h", aka precompiled header. Other questions or Wikipedia will answer that. In many cases a precompiled header can be avoided, especially if your project is small and with few dependencies. In your case, as you probably started from a template project, it was used to include Windows.h only for the _TCHAR macro.

Then, precompiled header is usually a per-project file in Visual Studio world, so:

1. Ensure you have the file "stdafx.h" in your project. If you don't (e.g. you removed it) just create a new temporary project and copy the default one from there;
2. Change the #include <stdafx.h> to #include "stdafx.h". It is supposed to be a project local file, not to be resolved in include directories.

Secondly: it's inadvisable to include the precompiled header in your own headers, to not clutter namespace of other source that can use your code as a library, so completely remove its inclusion in vector.h.

Here is a more robust implementation that handles abnormal input and race conditions.

• It detects unusually long input values and safely discards them. For example, if the source had an error and generated input without the expected terminator; or was malicious.
• It ensures the string value is always null terminated (even when buffer size is completely filled).
• It waits until the complete value is captured. For example, transmission delays could cause Serial.available() to return zero before the rest of the value finishes arriving.
• Does not skip values when multiple values arrive quicker than they can be processed (subject to the limitations of the serial input buffer).
• Can handle values that are a prefix of another value (e.g. "abc" and "abcd" can both be read in).

It deliberately uses character arrays instead of the String type, to be more efficient and to avoid memory problems. It also avoids using the readStringUntil() function, to not timeout before the input arrives.

The original question did not say how the variable length strings are defined, but I'll assume they are terminated by a single newline character - which turns this into a line reading problem.

int read_line(char* buffer, int bufsize)
{
  for (int index = 0; index < bufsize; index++) {
    // Wait until characters are available
    while (Serial.available() == 0) {
    }

    char ch = Serial.read(); // read next character
    Serial.print(ch); // echo it back: useful with the serial monitor (optional)

    if (ch == '\n') {
      buffer[index] = 0; // end of line reached: null terminate string
      return index; // success: return length of string (zero if string is empty)
    }

    buffer[index] = ch; // Append character to buffer
  }

  // Reached end of buffer, but have not seen the end-of-line yet.
  // Discard the rest of the line (safer than returning a partial line).

  char ch;
  do {
    // Wait until characters are available
    while (Serial.available() == 0) {
    }
    ch = Serial.read(); // read next character (and discard it)
    Serial.print(ch); // echo it back
  } while (ch != '\n');

  buffer[0] = 0; // set buffer to empty string even though it should not be used
  return -1; // error: return negative one to indicate the input was too long
}

Here is an example of it being used to read commands from the serial monitor:

const int LED_PIN = 13;
const int LINE_BUFFER_SIZE = 80; // max line length is one less than this

void setup() {
  pinMode(LED_PIN, OUTPUT);
  Serial.begin(9600);
}

void loop() {
  Serial.print("> ");

  // Read command

  char line[LINE_BUFFER_SIZE];
  if (read_line(line, sizeof(line)) < 0) {
    Serial.println("Error: line too long");
    return; // skip command processing and try again on next iteration of loop
  }

  // Process command

  if (strcmp(line, "off") == 0) {
      digitalWrite(LED_PIN, LOW);
  } else if (strcmp(line, "on") == 0) {
      digitalWrite(LED_PIN, HIGH);
  } else if (strcmp(line, "") == 0) {
    // Empty line: no command
  } else {
    Serial.print("Error: unknown command: \"");
    Serial.print(line);
    Serial.println("\" (available commands: \"off\", \"on\")");
  }
}

To perform Email Validation we have many ways,but simple & easiest way are two methods.

1- Using EditText(....).addTextChangedListener which keeps triggering on every input in an EditText box i.e email_id is invalid or valid

/**
 * Email Validation ex:- [email protected]
*/


final EditText emailValidate = (EditText)findViewById(R.id.textMessage); 

final TextView textView = (TextView)findViewById(R.id.text); 

String email = emailValidate.getText().toString().trim();

String emailPattern = "[a-zA-Z0-9._-]+@[a-z]+\\.+[a-z]+";

emailValidate .addTextChangedListener(new TextWatcher() { 
    public void afterTextChanged(Editable s) { 

    if (email.matches(emailPattern) && s.length() > 0)
        { 
            Toast.makeText(getApplicationContext(),"valid email address",Toast.LENGTH_SHORT).show();
            // or
            textView.setText("valid email");
        }
        else
        {
             Toast.makeText(getApplicationContext(),"Invalid email address",Toast.LENGTH_SHORT).show();
            //or
            textView.setText("invalid email");
        }
    } 
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    // other stuffs 
    } 
    public void onTextChanged(CharSequence s, int start, int before, int count) {
    // other stuffs 
    } 
}); 

2- Simplest method using if-else condition. Take the EditText box string using getText() and compare with pattern provided for email. If pattern doesn't match or macthes, onClick of button toast a message. It ll not trigger on every input of an character in EditText box . simple example shown below.

final EditText emailValidate = (EditText)findViewById(R.id.textMessage); 

final TextView textView = (TextView)findViewById(R.id.text); 

String email = emailValidate.getText().toString().trim();

String emailPattern = "[a-zA-Z0-9._-]+@[a-z]+\\.+[a-z]+";

// onClick of button perform this simplest code.
if (email.matches(emailPattern))
{
Toast.makeText(getApplicationContext(),"valid email address",Toast.LENGTH_SHORT).show();
}
else 
{
Toast.makeText(getApplicationContext(),"Invalid email address", Toast.LENGTH_SHORT).show();
}

when you are dealing with popups window.opener plays an important role, because we have to deal with fields of parent page as well as child page, when we have to use values on parent page we can use window.opener or we want some data on the child window or popup window at the time of loading then again we can set the values using window.opener

I just tried to show you the solution in a simple code

@IBAction func Button(sender : AnyObject) {
 if textField1.text != "" {
   // either textfield 1 is not empty then do this task
 }else{
   //show error here that textfield1 is empty
 }
}

Try using COUNT function like this

=IF(COUNT(SEARCH({"Romney","Obama","Gingrich"},C1)),1,"")

Note that you don't need the wildcards (as teylyn says) and unless there's a specific reason "1" doesn't need quotes (in fact that makes it a text value)

Epsilon is your "fuzz factor," since doubles may not be exactly equal. Epsilon lets you describe how close they have to be.

If you were expecting 3.14159 but would take anywhere from 3.14059 to 3.14259 (that is, within 0.001), then you should write something like

double myPi = 22.0d / 7.0d; //Don't use this in real life!
assertEquals(3.14159, myPi, 0.001);

(By the way, 22/7 comes out to 3.1428+, and would fail the assertion. This is a good thing.)

This might be what you're looking for:

// ... rest of code

// copy your state.data to a new array and sort it by itemM in ascending order
// and then map 
const myData = [].concat(this.state.data)
    .sort((a, b) => a.itemM > b.itemM ? 1 : -1)
    .map((item, i) => 
        <div key={i}> {item.matchID} {item.timeM}{item.description}</div>
    );

// render your data here...

The method sort will mutate the original array . Hence I create a new array using the concat method. The sorting on the field itemM should work on sortable entities like string and numbers.

You should consider that a "true value" is everything except 0 and not only 1. So instead of 1=1 you should write 1<>0.

Because when you will use parameter (@param <> 0) you could have some conversion issue.

The most know is Access which translate True value on control as -1 instead of 1.

So you cant have the behavior that you want but you can do something that feels like it. You want to be able to do Choice.first.question

what I have done in the past is something like this

class Choice
  belongs_to :user
  belongs_to :answer
  validates_uniqueness_of :answer_id, :scope => [ :question_id, :user_id ]
  ...
  def question
    answer.question
  end
end

this way the you can now call question on Choice

2020 : Similar Issue

If your content is a set of buttons that you want to center on a page, then wrap them in a row and use justify-content-center.

Sample code below:

<div class="row justify-content-center">

    <button>Action A</button>
    <button>Action B</button>
    <button>Action C</button> 

</div>

There are many ways, one is to use a counter:

$i = 0;
foreach ($arr as $k => $v) {
    /* Do stuff */
    if (++$i == 2) break;
}

Other way would be to slice the first 2 elements, this isn't as efficient though:

foreach (array_slice($arr, 0, 2) as $k => $v) {
    /* Do stuff */
}

You could also do something like this (basically the same as the first foreach, but with for):

for ($i = 0, reset($arr); list($k,$v) = each($arr) && $i < 2; $i++) {
}

The problem could also be due to any output streams that you have forgotten to close. In my case I was working with the file before the file being deleted. However at one place in the file operations, I had forgotten to close an output stream that I used to write to the file that was attempted to delete later.

Using a simple SELECT query is - in my opinion - quite reliable. Most of all it can check table existence in many different database types (SQLite / MySQL).

SELECT 1 FROM table;

It makes sense when you can use other reliable mechanism for determining if the query succeeded (for example, you query a database via QSqlQuery in Qt).

I need something similiar with angular reactive form:

let myMap = new Map().set(0, {status: 'VALID'}).set(1, {status: 'INVALID'});
let mapToArray = Array.from(myMap.values());
let isValid = mapToArray.every(x => x.status === 'VALID');

I had problems with all the other solutions offered but ended up doing this simple thing that is smooth as butter.

Set up your HTML like so:

<tr id=row1 style='height:0px'><td>
  <div id=div1 style='display:none'>
    Hidden row content goes here
  </div>
</td></tr>

Then set up your javascript like so:

function toggleRow(rowid){
  var row = document.getElementById("row" + rowid)

  if(row.style.height == "0px"){
      $('#div' + rowid).slideDown('fast');
      row.style.height = "1px";   
  }else{
      $('#div' + rowid).slideUp('fast');
      row.style.height = "0px";   
  } 
}

Basically, make the "invisible" row 0px high, with a div inside.
Use the animation on the div (not the row) and then set the row height to 1px.

To hide the row again, use the opposite animation on the div and set the row height back to 0px.

You probably want to use a CASE expression.

They look like this:

SELECT col1, col2, (case when (action = 2 and state = 0) 
 THEN
      1 
 ELSE
      0 
 END)
 as state from tbl1;

If you'd like to set this globally for all users of a machine, you can create the following directory and file structures:

mkdir %windir%\Sun\Java\Deployment

Create a file deployment.config with the content:

deployment.system.config=file:///c:/windows/Sun/Java/Deployment/deployment.properties
deployment.system.config.mandatory=TRUE

Create a file deployment.properties

deployment.user.security.exception.sites=C\:/WINDOWS/Sun/Java/Deployment/exception.sites

Create a file exception.sites

http://example1.com
http://example2.com/path/to/specific/directory/

Reference https://blogs.oracle.com/java-platform-group/entry/upcoming_exception_site_list_in

First thing, you don't need to write

ResultSet rs = stmt.executeQuery(sql);

just write

ResultSet rs = stmt.executeQuery();

The above mentioned syntax is used for Statements not for PreparedStatement.

Second thing, rs.next() checks if the result set contains any values or not. It returns a boolean value as well as it moves the cursor to the first value in the result set because initially it is at BEFORE FIRST Position. So if you want to access first value in result set, you need to write rs.next().

I didn't think your question was very clear, but if all you need is a unique file name...

import uuid

unique_filename = str(uuid.uuid4())

Further to the answer by Jon Skeet, which uses this example code:

// Illegal code - because otherwise life would be Bad
List<Dog> dogs = new ArrayList<Dog>(); // ArrayList implements List
List<Animal> animals = dogs; // Awooga awooga
animals.add(new Cat());
Dog dog = dogs.get(0); // This should be safe, right?

At the deepest level, the problem here is that dogs and animals share a reference. That means that one way to make this work would be to copy the entire list, which would break reference equality:

// This code is fine
List<Dog> dogs = new ArrayList<Dog>();
dogs.add(new Dog());
List<Animal> animals = new ArrayList<>(dogs); // Copy list
animals.add(new Cat());
Dog dog = dogs.get(0);   // This is fine now, because it does not return the Cat

After calling List<Animal> animals = new ArrayList<>(dogs);, you cannot subsequently directly assign animals to either dogs or cats:

// These are both illegal
dogs = animals;
cats = animals;

therefore you can't put the wrong subtype of Animal into the list, because there is no wrong subtype -- any object of subtype ? extends Animal can be added to animals.

Obviously, this changes the semantics, since the lists animals and dogs are no longer shared, so adding to one list does not add to the other (which is exactly what you want, to avoid the problem that a Cat could be added to a list that is only supposed to contain Dog objects). Also, copying the entire list can be inefficient. However, this does solve the type equivalence problem, by breaking reference equality.

The problem could be that we need to specifically give adb root access in the developnent options in the latest CMs.. Here is what i did.

abc@abc-L655:~$ sudo adb kill-server
abc@abc-L655:~$ sudo adb root start-server * daemon not running. starting it now on port 5037 * * daemon started successfully * root access is disabled by system setting - enable in settings -> development options

after altering the development options...

abc@abc-L655:~$ sudo adb kill-server
abc@abc-L655:~$ sudo adb root start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
restarting adbd as root
abc@abc-L655:~$ adb shell
root@android:/ # ls /data/ .... good to go.. 

Using moment.js, you can use keepOffset parameter of toISOString:

toISOString(keepOffset?: boolean): string;

moment().toISOString(true)

public List<string> GetPropertiesNameOfClass(object pObject)
{
    List<string> propertyList = new List<string>();
    if (pObject != null)
    {
        foreach (var prop in pObject.GetType().GetProperties())
        {
            propertyList.Add(prop.Name);
        }
    }
    return propertyList;
}

This function is for getting list of Class Properties.

You can do it on the fly. You don't need to call (Ctrl+Shift+O) or "Project/Optimize Imports..." each time.

Just set this checkbox in Settings -> Editor -> General -> Auto Import -> Optimize Imports on the fly.

Try this code.

For showing Softkeyboard:

InputMethodManager imm = (InputMethodManager)
                                 getSystemService(Context.INPUT_METHOD_SERVICE);
if(imm != null){
        imm.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, 0);
    }

For Hiding SoftKeyboard -

InputMethodManager imm = (InputMethodManager)
                                  getSystemService(Context.INPUT_METHOD_SERVICE);
if(imm != null){
        imm.toggleSoftInput(0, InputMethodManager.HIDE_IMPLICIT_ONLY);
    }

As stated from David Cournapeau, use figure().

import matplotlib
import matplotlib.pyplot as plt
import matplotlib.mlab as mlab

plt.figure()
x = [1,10]
y = [30, 1000]
plt.loglog(x, y, basex=10, basey=10, ls="-")
plt.savefig("first.ps")


plt.figure()
x = [10,100]
y = [10, 10000]
plt.loglog(x, y, basex=10, basey=10, ls="-")
plt.savefig("second.ps")

Or subplot(121) / subplot(122) for the same plot, different position.

import matplotlib
import matplotlib.pyplot as plt
import matplotlib.mlab as mlab

plt.subplot(121)
x = [1,10]
y = [30, 1000]
plt.loglog(x, y, basex=10, basey=10, ls="-")

plt.subplot(122)
x = [10,100]
y = [10, 10000]
plt.loglog(x, y, basex=10, basey=10, ls="-")
plt.savefig("second.ps")

@Alan's answer will do what you're looking for, but this solution fails when you use the responsive capabilities of Bootstrap. In your case, you're using the xs sizes so you won't notice, but if you used anything else (e.g. col-sm, col-md, etc), you'd understand.

Another approach is to play with margins and padding. See the updated fiddle: http://jsfiddle.net/jz8j247x/1/

.left-side {
  background-color: blue;
  padding-bottom: 1000px;
  margin-bottom: -1000px;
  height: 100%;
}
.something {
  height: 100%;
  background-color: red;
  padding-bottom: 1000px;
  margin-bottom: -1000px;
  height: 100%;
}
.row {
  background-color: green;
  overflow: hidden;
}

After you malloc a node make sure to set node->next = NULL.

int addNodeBottom(int val, node *head)
{    
    node *current = head;
    node *newNode = (node *) malloc(sizeof(node));
    if (newNode == NULL) {
        printf("malloc failed\n");
        exit(-1);
    }    

    newNode->value = val;
    newNode->next = NULL;

    while (current->next) {
        current = current->next;
    }    
    current->next = newNode;
    return 0;
}    

I should point out that with this version the head is still used as a dummy, not used for storing a value. This lets you represent an empty list by having just a head node.

use this function to create and set attributes at the same time

function createNode(node, attributes){
    const el = document.createElement(node);
    for(let key in attributes){
        el.setAttribute(key, attributes[key]);
    }
    return el;
}

use it like so

const input = createNode('input', {
    name: 'test',
    type: 'text',
    placeholder: 'Test'
});
document.body.appendChild(input);

require 5.013002; # or better:    use Syntax::Construct qw(/r);
print "bla: ", $myvar =~ s/a/b/r, "\n";

See perl5132delta:

The substitution operator now supports a /r option that copies the input variable, carries out the substitution on the copy and returns the result. The original remains unmodified.

my $old = 'cat';
my $new = $old =~ s/cat/dog/r;
# $old is 'cat' and $new is 'dog'

Don't Return Empty Json

In My Case I was returning Empty Json String in .Net Core Web API Project.

So I Changed My Code

From

 return Ok();

To

 return Ok("Done");

It seems you have to return some string or object.

Hope this helps.

It depends on which Ruby version you use:

Ruby 2.4 and higher:

It just works, as since Ruby v2.4.0 supports Unicode case mapping:

"?????".capitalize #=> ?????

Ruby 2.3 and lower:

"maria".capitalize #=> "Maria"
"?????".capitalize #=> ?????

The problem is, it just doesn't do what you want it to, it outputs ????? instead of ?????.

If you're using Rails there's an easy workaround:

"?????".mb_chars.capitalize.to_s # requires ActiveSupport::Multibyte

Otherwise, you'll have to install the unicode gem and use it like this:

require 'unicode'

Unicode::capitalize("?????") #=> ?????

Ruby 1.8:

Be sure to use the coding magic comment:

#!/usr/bin/env ruby

puts "?????".capitalize

gives invalid multibyte char (US-ASCII), while:

#!/usr/bin/env ruby
#coding: utf-8

puts "?????".capitalize

works without errors, but also see the "Ruby 2.3 and lower" section for real capitalization.

I solved the problem switching the workspace.

1. Go to File (Switch workspace)
2. Select the destination and create a folder named Workspace
3. Run a Hello World and close Eclipse (notice that Eclipse creates the folder RemoteSystemsTempFiles automatically)
4. now copy all your projects into the new folder Workspace
5. Open Eclipse and if necessary (sometimes Eclipse does not show the projects) import all of them (go to File/ Open projects from File System)

This issue also bother me and then i find possible cases to reproduce this issue

when i run my window in administrator then it working fine ng but when i run this in my second space like other user then i got this issue.

so if i want to run my angular application then i need to run this command

npm run ng serve which is working but when i run the command with --host npm run ng server --host IP it not working given some error

so i find some possible solution 1. go appdata and then user\admin\AppData\Roaming\npm folder then copy this path but if you using other user account user\newuser\AppData\Roaming\npm folder you can copy this npm folder from other user i.e admin user account. if you do not want to copy this folder then copy the path of ****user\admin\AppData\Roaming\npm folder**** folder and then open your environment variable setting and add this path in path variable name

enter this path in system path variable not user variable C:\Users\admin\AppData\Roaming\npm

and run the command prompt as administrator then run ng command it will work
