At the present time, there is a simple way to fix this problem:

1. Go to Tools ? MarketPlace and search for "PDI MySQL Plugin"
2. Install it ( this will automatically install the missing driver here: data-integration\plugins\databases\pdi-mysql-plugin\lib )
3. Restart Pentaho
4. Done.

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

It is also possible to open the pdf link in a new window and let the browser handle the rest:

window.open(pdfUrl, '_blank');

or:

window.open(pdfUrl);

Edit: Garth's answer is probably better.

My old answer text is preserved below.

To convert a string to a stream, you can use a paused through stream:

through().pause().queue('your string').end()

Example:

var through = require('through')

// Create a paused stream and buffer some data into it:
var stream = through().pause().queue('your string').end()

// Pass stream around:
callback(null, stream)

// Now that a consumer has attached, remember to resume the stream:
stream.resume()

The error comes up when you are trying to assign a list of numpy array of different length to a data frame, and it can be reproduced as follows:

A data frame of four rows:

df = pd.DataFrame({'A': [1,2,3,4]})

Now trying to assign a list/array of two elements to it:

df['B'] = [3,4]   # or df['B'] = np.array([3,4])

Both errors out:

ValueError: Length of values does not match length of index

Because the data frame has four rows but the list and array has only two elements.

Work around Solution (use with caution): convert the list/array to a pandas Series, and then when you do assignment, missing index in the Series will be filled with NaN:

df['B'] = pd.Series([3,4])

df
#   A     B
#0  1   3.0
#1  2   4.0
#2  3   NaN          # NaN because the value at index 2 and 3 doesn't exist in the Series
#3  4   NaN

For your specific problem, if you don't care about the index or the correspondence of values between columns, you can reset index for each column after dropping the duplicates:

df.apply(lambda col: col.drop_duplicates().reset_index(drop=True))

#   A     B
#0  1   1.0
#1  2   5.0
#2  7   9.0
#3  8   NaN

Hi every one this code is workin for me please try with this for sending mail to multiple recepients

private String recipient = "[email protected] ,[email protected] ";
String[] recipientList = recipient.split(",");
InternetAddress[] recipientAddress = new InternetAddress[recipientList.length];
int counter = 0;
for (String recipient : recipientList) {
    recipientAddress[counter] = new InternetAddress(recipient.trim());
    counter++;
}
message.setRecipients(Message.RecipientType.TO, recipientAddress);

run this query before creating or altering table.

SET @@global.innodb_large_prefix = 1;

this will set max key length to 3072 bytes

Using the Window.URL API - https://developer.mozilla.org/en-US/docs/Web/API/Window/URL

Works with http(s), ports etc.

var url = new URL('/path/to/websocket', window.location.href);

url.protocol = url.protocol.replace('http', 'ws');

url.href // => ws://www.example.com:9999/path/to/websocket

Alternative escaping syntax:

LIKE Wildcard Literals

The JDBC driver supports the {escape 'escape character'} syntax for using LIKE clause wildcards as literals.

SELECT *
FROM tab
WHERE col LIKE 'a\_c' {escape '\'};

db<>fiddle demo

var byteCharacters = atob(response.data);
var byteNumbers = new Array(byteCharacters.length);
for (var i = 0; i < byteCharacters.length; i++) {
  byteNumbers[i] = byteCharacters.charCodeAt(i);
}
var byteArray = new Uint8Array(byteNumbers);
var file = new Blob([byteArray], { type: 'application/pdf;base64' });
var fileURL = URL.createObjectURL(file);
window.open(fileURL);

You return a base64 string from the API or another source. You can also download it.

There is a way to filter Safari 5+ from Chrome:

@media screen and (-webkit-min-device-pixel-ratio:0) { 
    /* Safari and Chrome */
    .myClass {
     color:red;
    }

    /* Safari only override */
    ::i-block-chrome,.myClass {
     color:blue;
    }
}

Using Kotlin

    val data = "{\"ApiInfo\":{\"description\":\"userDetails\",\"status\":\"success\"},\"userDetails\":{\"Name\":\"somename\",\"userName\":\"value\"},\"pendingPushDetails\":[]}\n"
    
try {
      val jsonObject = JSONObject(data)
      val infoObj = jsonObject.getJSONObject("ApiInfo")
    } catch (e: Exception) {
    }

Use below code in your xml file

<ListView 
    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:divider="#000000" 
    android:dividerHeight="1dp">
</ListView> 

First of all it is unclear what type name has. If it has the type std::string then instead of

string nametext;
nametext = "Your name is" << name;

you should write

std::string nametext = "Your name is " + name;

where operator + serves to concatenate strings.

If name is a character array then you may not use operator + for two character arrays (the string literal is also a character array), because character arrays in expressions are implicitly converted to pointers by the compiler. In this case you could write

std::string nametext( "Your name is " );
nametext.append( name );

or

std::string nametext( "Your name is " );
nametext += name;

Python 3.6+:

>>> i = 240
>>> f'{i:02x}'
'f0'

A performance comparison:

import itertools
import timeit
big_list = [[0]*1000 for i in range(1000)]
timeit.repeat(lambda: list(itertools.chain.from_iterable(big_list)), number=100)
timeit.repeat(lambda: list(itertools.chain(*big_list)), number=100)
timeit.repeat(lambda: (lambda b: map(b.extend, big_list))([]), number=100)
timeit.repeat(lambda: [el for list_ in big_list for el in list_], number=100)
[100*x for x in timeit.repeat(lambda: sum(big_list, []), number=1)]

Producing:

>>> import itertools
>>> import timeit
>>> big_list = [[0]*1000 for i in range(1000)]
>>> timeit.repeat(lambda: list(itertools.chain.from_iterable(big_list)), number=100)
[3.016212113769325, 3.0148865239060227, 3.0126415732791028]
>>> timeit.repeat(lambda: list(itertools.chain(*big_list)), number=100)
[3.019953987082083, 3.528754223385439, 3.02181439266457]
>>> timeit.repeat(lambda: (lambda b: map(b.extend, big_list))([]), number=100)
[1.812084445152557, 1.7702404451095965, 1.7722977998725362]
>>> timeit.repeat(lambda: [el for list_ in big_list for el in list_], number=100)
[5.409658160700605, 5.477502077679354, 5.444318360412744]
>>> [100*x for x in timeit.repeat(lambda: sum(big_list, []), number=1)]
[399.27587954973444, 400.9240571138051, 403.7521153804846]

This is with Python 2.7.1 on Windows XP 32-bit, but @temoto in the comments above got from_iterable to be faster than map+extend, so it's quite platform and input dependent.

Stay away from sum(big_list, [])

I was using it in that way:

if [ $(getent passwd $user) ] ; then
        echo user $user exists
else
        echo user $user doesn\'t exists
fi

In my case, my Dockerfile is written like a template containing placeholders which I'm replacing with real value using my configuration file.

So I couldn't specify this file directly but pipe it into the docker build like this:

sed "s/%email_address%/$EMAIL_ADDRESS/;" ./Dockerfile | docker build -t katzda/bookings:latest . -f -;

But because of the pipe, the COPY command didn't work. But the above way solves it by -f - (explicitly saying file not provided). Doing only - without the -f flag, the context AND the Dockerfile are not provided which is a caveat.

Your syntax and logic are incorrect in a number of ways. You need to create an index variable and use it to access the array's elements, like so:

int i = 0;        // Create a separate integer to serve as your array indexer.
while(i < 10) {   // The indexer needs to be less than 10, not A itself.
   sum += A[i];   // either sum = sum + ... or sum += ..., but not both
   i++;           // You need to increment the index at the end of the loop.
}

The above example uses a while loop, since that's the approach you took. A more appropriate construct would be a for loop, as in Bogdan's answer.

Run the command java -X and you will get a list of all -X options:

C:\Users\Admin>java -X
-Xmixed           mixed mode execution (default)
-Xint             interpreted mode execution only
-Xbootclasspath:<directories and zip/jar files separated by ;>
                      set search path for bootstrap classes and resources
-Xbootclasspath/a:<directories and zip/jar files separated by ;>
                      append to end of bootstrap class path
-Xbootclasspath/p:<directories and zip/jar files separated by ;>
                      prepend in front of bootstrap class path
-Xdiag            show additional diagnostic messages
-Xnoclassgc       disable class garbage collection
-Xincgc           enable incremental garbage collection
-Xloggc:<file>    log GC status to a file with time stamps
-Xbatch           disable background compilation
-Xms<size>        set initial Java heap size.........................
-Xmx<size>        set maximum Java heap size.........................
-Xss<size>        set java thread stack size
-Xprof            output cpu profiling data
-Xfuture          enable strictest checks, anticipating future default
-Xrs              reduce use of OS signals by Java/VM (see documentation)
-Xcheck:jni       perform additional checks for JNI functions
-Xshare:off       do not attempt to use shared class data
-Xshare:auto      use shared class data if possible (default)
-Xshare:on        require using shared class data, otherwise fail.
-XshowSettings    show all settings and continue
-XshowSettings:all         show all settings and continue
-XshowSettings:vm          show all vm related settings and continue
-XshowSettings:properties  show all property settings and continue
-XshowSettings:locale      show all locale related settings and continue

The -X options are non-standard and subject to change without notice.

I hope this will help you understand Xms, Xmx as well as many other things that matters the most. :)

Try renaming the default file. In my case, a recent move to IIS7.5 gave the 405 error. I changed index.aspx to default.aspx and it worked immediately for me.

dir() is the simple way. See here:

Guide To Python Introspection

I think the most correct answer, assuming the use of jQuery, is a consolidation of aspects of all the answers in this page, plus the use of the event that Bootstrap passes:

$(document).on('shown.bs.modal', function(e) {
  $('input:visible:enabled:first', e.target).focus();
});

It also would work changing $(document) to $('.modal') or to add a class to the modal that signals that this focus should occur, like $('.modal.focus-on-first-input')

Signing the third party assembly worked for me:

EDIT: I've learned that it's helpful to post steps in case the linked article is no longer valid. All credit goes to Hiren Khirsaria:

1. Run visual studio command prompt and go to directory where your DLL located.

   For Example my DLL is located in D:/hiren/Test.dll

2. Now create the IL file using the command below.

   D:/hiren> ildasm /all /out=Test.il Test.dll (this command generates the code library)

3. Generate new key to sign your project.

   D:/hiren> sn -k mykey.snk

4. Now sign your library using ilasm command.

   D:/hiren> ilasm /dll /key=mykey.snk Test.il

I had a similar problem recently and found an interesting solution. Basically I needed to deserialize following nested JSON String into my POJO:

"{\"restaurant\":{\"id\":\"abc-012\",\"name\":\"good restaurant\",\"foodType\":\"American\",\"phoneNumber\":\"123-456-7890\",\"currency\":\"USD\",\"website\":\"website.com\",\"location\":{\"address\":{\"street\":\" Good Street\",\"city\":\"Good City\",\"state\":\"CA\",\"country\":\"USA\",\"postalCode\":\"12345\"},\"coordinates\":{\"latitude\":\"00.7904692\",\"longitude\":\"-000.4047208\"}},\"restaurantUser\":{\"firstName\":\"test\",\"lastName\":\"test\",\"email\":\"[email protected]\",\"title\":\"server\",\"phone\":\"0000000000\"}}}"

I ended up using regex to remove the open quotes from beginning and the end of JSON and then used apache.commons unescapeJava() method to unescape it. Basically passed the unclean JSON into following method to get back a cleansed one:

private String removeQuotesAndUnescape(String uncleanJson) {
    String noQuotes = uncleanJson.replaceAll("^\"|\"$", "");

    return StringEscapeUtils.unescapeJava(noQuotes);
}

then used Google GSON to parse it into my own Object:

MyObject myObject = new.Gson().fromJson(this.removeQuotesAndUnescape(uncleanJson));

When you subtract two dates in Oracle, you get the number of days between the two values. So you just have to multiply to get the result in minutes instead:

SELECT (date2 - date1) * 24 * 60 AS minutesBetween
FROM ...

You can have awk do it all without using cut:

awk '{print substr($7,index($7,"=")+1)}' inputfile

You could use split() instead of substr(index()).

Even in base Python you can do the computation in generic form

result = sum(x**2 for x in some_vector) ** 0.5

x ** 2 is surely not an hack and the computation performed is the same (I checked with cpython source code). I actually find it more readable (and readability counts).

Using instead x ** 0.5 to take the square root doesn't do the exact same computations as math.sqrt as the former (probably) is computed using logarithms and the latter (probably) using the specific numeric instruction of the math processor.

I often use x ** 0.5 simply because I don't want to add math just for that. I'd expect however a specific instruction for the square root to work better (more accurately) than a multi-step operation with logarithms.

UPDATE:

onActivityCreated() is deprecated from API Level 28.

onCreate():

The onCreate() method in a Fragment is called after the Activity's onAttachFragment() but before that Fragment's onCreateView().
In this method, you can assign variables, get Intent extras, and anything else that doesn't involve the View hierarchy (i.e. non-graphical initialisations). This is because this method can be called when the Activity's onCreate() is not finished, and so trying to access the View hierarchy here may result in a crash.

onCreateView():

After the onCreate() is called (in the Fragment), the Fragment's onCreateView() is called. You can assign your View variables and do any graphical initialisations. You are expected to return a View from this method, and this is the main UI view, but if your Fragment does not use any layouts or graphics, you can return null (happens by default if you don't override).

onActivityCreated():

As the name states, this is called after the Activity's onCreate() has completed. It is called after onCreateView(), and is mainly used for final initialisations (for example, modifying UI elements). This is deprecated from API level 28.

To sum up...
... they are all called in the Fragment but are called at different times.
The onCreate() is called first, for doing any non-graphical initialisations. Next, you can assign and declare any View variables you want to use in onCreateView(). Afterwards, use onActivityCreated() to do any final initialisations you want to do once everything has completed.

If you want to view the official Android documentation, it can be found here:

• onCreate()
• onCreateView()
• onActivityCreated()_

There are also some slightly different, but less developed questions/answers here on Stack Overflow:

• onCreate() vs onCreateView()
• onCreateView() vs onActivityCreated()

As you can see in the documentation of JSHint you can change options per function or per file. In your case just place a comment in your file or even more local just in the function that uses eval:

/*jshint evil:true */

function helloEval(str) {
    /*jshint evil:true */
    eval(str);
}

I modified my activate script to source the file .virtualenvrc, if it exists in the current directory, and to save/restore PYTHONPATH on activate/deactivate.

You can find the patched activate script here.. It's a drop-in replacement for the activate script created by virtualenv 1.11.6.

Then I added something like this to my .virtualenvrc:

export PYTHONPATH="${PYTHONPATH:+$PYTHONPATH:}/some/library/path"

You CAN include a modal within a form. In the Bootstrap documentation it recommends the modal to be a "top level" element, but it still works within a form.

You create a form, and then the modal "save" button will be a button of type="submit" to submit the form from within the modal.

<form asp-action="AddUsersToRole" method="POST" class="mb-3">

    @await Html.PartialAsync("~/Views/Users/_SelectList.cshtml", Model.Users)

    <div class="modal fade" id="role-select-modal" tabindex="-1" role="dialog" aria-labelledby="role-select-modal" aria-hidden="true">
        <div class="modal-dialog" role="document">
            <div class="modal-content">
                <div class="modal-header">
                    <h5 class="modal-title" id="exampleModalLabel">Select a Role</h5>
                </div>
                <div class="modal-body">
                    ...
                </div>
                <div class="modal-footer">
                    <button type="submit" class="btn btn-primary">Add Users to Role</button>
                    <button type="button" class="btn btn-secondary" data-dismiss="modal">Cancel</button>
                </div>
            </div>
        </div>
    </div>

</form>

You can post (or GET) your form data to any URL. By default it is the serving page URL, but you can change it by setting the form action. You do not have to use ajax.

Mozilla documentation on form action

There is a tool from Microsoft to convert java to C#. For the opposite direction take a look here and here. If this doesn't work out, it should not take too long to convert the source manually because C# and java are very similar,

I found this worked in my scenario.

The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callback methods introduced in jQuery 1.5 are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

$.get("urlToCheck.com").done(function () {
  alert("success");
}).fail(function () {
   alert("failed.");
});

The following gives pixel-perfect consistency across browsers, even IE9:

The approach is quite sensible, to the point of being obvious:

1. Create an input and a label.
2. Display them as block, so you can float them as you like.
3. Set the height and the line-height to the same value to ensure they center and align vertically.
4. For em measurements, to calculate the height of the elements, the browser must know the height of the font for those elements, and it must not itself be set in em measurements.

This results in a globally applicable general rule:

input, label {display:block;float:left;height:1em;line-height:1em;}

With font size adaptable per form, fieldset or element.

#myform input, #myform label {font-size:20px;}

Tested in latest Chrome, Safari, and Firefox on Mac, Windows, Iphone, and Android. And IE9.

This method is likely applicable to all input types that are not higher than one line of text. Apply a type rule to suit.

Set separatorInset.right = .greatestFiniteMagnitude on your cell.

protected override bool ProcessCmdKey(ref Message msg, Keys dataKey)
    {
        if (dataKey == Keys.Escape)
        {
            this.Close();
            //this.Visible = false;
            //Plus clear values from form, if Visible false.
        }
        return base.ProcessCmdKey(ref msg, dataKey);
    }

If you are using .NET then Json.NET supports LINQ queries over the top of JSON. This post has some examples. It supports filtering, mapping, grouping, etc.

Message box is only defaultly available for windows form application.If you want to use the message box resource the you would have to use 'using system.windows.forms' to enable the message box for web forms mode.

If you mean how to remove the 'checked' state from all checkboxes:

$('input:checkbox').removeAttr('checked');

use jquery :  $("#id").css("background","red");

Android Studio 2.2 came out with the ability to use ndk-build and cMake. Though, we had to wait til 2.2.3 for the Application.mk support. I've tried it, it works...though, my variables aren't showing up in the debugger. I can still query them via command line though.

You need to do something like this:

externalNativeBuild{
   ndkBuild{
        path "Android.mk"
    }
}

defaultConfig {
  externalNativeBuild{
    ndkBuild {
      arguments "NDK_APPLICATION_MK:=Application.mk"
      cFlags "-DTEST_C_FLAG1"  "-DTEST_C_FLAG2"
      cppFlags "-DTEST_CPP_FLAG2"  "-DTEST_CPP_FLAG2"
      abiFilters "armeabi-v7a", "armeabi"
    }
  } 
}

See http://tools.android.com/tech-docs/external-c-builds

NB: The extra nesting of externalNativeBuild inside defaultConfig was a breaking change introduced with Android Studio 2.2 Preview 5 (July 8, 2016). See the release notes at the above link.

2019 update: Use NVM to install node, not Homebrew

In most of the answers , recommended way to install nvm is to use Homebrew

Do not do that

At Github Page for nvm it is clearly called out:

Homebrew installation is not supported. If you have issues with homebrew-installed nvm, please brew uninstall it, and install it using the instructions below, before filing an issue.

Use the following method instead

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

The script clones the nvm repository to ~/.nvm and adds the source line to your profile (~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc).

And then use nvm to install node. For example to install latest LTS version do:

nvm install v8.11.1

Clean and hassle free. It would mark this as your default node version as well so you should be all set

Use FLOOR(), if you want to round your decimal to the lower integer. Examples:

FLOOR(1.9) => 1
FLOOR(1.1) => 1

Use ROUND(), if you want to round your decimal to the nearest integer. Examples:

ROUND(1.9) => 2
ROUND(1.1) => 1

Use CEIL(), if you want to round your decimal to the upper integer. Examples:

CEIL(1.9) => 2
CEIL(1.1) => 2

For anyone trying to use jQuery.active with JSONP requests (like I was) you'll need enable it with this:

jQuery.ajaxPrefilter(function( options ) {
    options.global = true;
});

Keep in mind that you'll need a timeout on your JSONP request to catch failures.

You can try using JavaScript's Date Object

new Date(year,month).getFullYear()%4==0

This will return true or false.

Note: you should use the accepted answer if possible. It's better than mine.

It's quite easy with the GD library.

It's built in usually, you probably have it (use phpinfo() to check)

$image = imagecreatefromjpeg("http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com");

imagejpeg($image, "folder/file.jpg");

The above answer is better (faster) for most situations, but with GD you can also modify it in some form (cropping for example).

$image = imagecreatefromjpeg("http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com");
imagecopy($image, $image, 0, 140, 0, 0, imagesx($image), imagesy($image));
imagejpeg($image, "folder/file.jpg");

This only works if allow_url_fopen is true (it is by default)

I wanted to import certificate for smtp.gmail.com

Only solution worked for me is 1. Enter command to view this certificate

D:\openssl\bin\openssl.exe s_client -connect smtp.gmail.com:465

2. Copy and save the lines between "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----" into a file, gmail.cer

3. Run

   keytool -import -alias smtp.gmail.com -keystore "%JAVA_HOME%/jre/lib/security/cacerts" -file C:\Users\Admin\Desktop\gmail.cer

4. Enter password chageit

5. Click yes to import the certificate

6. Restart java

now run the command and you are good to go

Try this:

var res = list.ToDictionary(x => x, x => x);

The first lambda lets you pick the key, the second one picks the value.

You can play with it and make values differ from the keys, like this:

var res = list.ToDictionary(x => x, x => string.Format("Val: {0}", x));

If your list contains duplicates, add Distinct() like this:

var res = list.Distinct().ToDictionary(x => x, x => x);

EDIT To comment on the valid reason, I think the only reason that could be valid for conversions like this is that at some point the keys and the values in the resultant dictionary are going to diverge. For example, you would do an initial conversion, and then replace some of the values with something else. If the keys and the values are always going to be the same, HashSet<String> would provide a much better fit for your situation:

var res = new HashSet<string>(list);
if (res.Contains("string1")) ...

I submit that it is better to leave your data stacked as it is:

df = pandas.DataFrame(data, columns=['R_Number', 'C_Number', 'Avg', 'Std'])

# Possibly also this if these can always be the indexes:
# df = df.set_index(['R_Number', 'C_Number'])

Then it's a bit more intuitive to say

df.set_index(['R_Number', 'C_Number']).Avg.unstack(level=1)

This way it is implicit that you're seeking to reshape the averages, or the standard deviations. Whereas, just using pivot, it's purely based on column convention as to what semantic entity it is that you are reshaping.

Questions : how to check File is empty or not?

Ans: I have slove this issue using this Jquery code

The href property sets or returns the value of the href attribute of a link.

  var hello = domains[i].getElementsByTagName('a')[0].getAttribute('href');
    var url="https://www.google.com/";
    console.log( url+hello);

Unfortunately there is no such a thing as Lock/Unlock. What you have to do is:

1. Click on "Filter Current Log..."
2. Select the XML tab and click on "Edit query manually"

3. Enter the below query:

   <QueryList>
     <Query Id="0" Path="Security">
       <Select Path="Security">
       *[EventData[Data[@Name='LogonType']='7']
        and
        (System[(EventID='4634')] or System[(EventID='4624')])
        ]</Select>
     </Query>
   </QueryList>
   

That's it

Since every control element gets referenced with its name on the form element (see forms specs), controls with name "submit" will override the build-in submit function.

Which leads to the error mentioned in comments above:

Uncaught TypeError: Property 'submit' of object #<HTMLFormElement> is not a function

As in the accepted answer above the simplest solution would be to change the name of that control element.

However another solution could be to use dispatchEvent method on form element:

$("#form_id")[0].dispatchEvent(new Event('submit')); 

One solution: add isAdmin: 0/1 flag to your post collection document.

Other solution: use DBrefs

A bit twiddling method...

>>> bin8 = lambda x : ''.join(reversed( [str((x >> i) & 1) for i in range(8)] ) )
>>> bin8(6)
'00000110'
>>> bin8(-3)
'11111101'

Express makes this kind of stuff really intuitive. The syntax looks like below :

var app = require('express').createServer();
app.get("/string", function(req, res) {
    var strings = ["rad", "bla", "ska"]
    var n = Math.floor(Math.random() * strings.length)
    res.send(strings[n])
})
app.listen(8001)

If you're using jQuery on the client side you can do something like this:

$.get("/string", function(string) {
    alert(string)
})

All these suggestions work unless you put the anchors inside an UL list.

<ul>
    <li>
        <a>click me</a>>
    </li>
</ul>

Then any cascade style sheet rules are overridden in the Chrome browser. The width becomes auto. Then you must use inline CSS rules directly on the anchor itself.

a.button a:hover means "a link that's being hovered over that is a child of a link with the class button".

Go instead for a.button:hover.

You can also declare it HTML safe from the code:

from flask import Markup
value = Markup('<strong>The HTML String</strong>')

Then pass that value to the templates and they don't have to |safe it.

When you use

@GeneratedValue(strategy=GenerationType.AUTO)

or

@GeneratedValue which is short hand way of the above, Hibernate starts to decide the best generation strategy for you, in this case it has selected

GenerationType.SEQUENCE as the strategy and that is why it is looking for

schemaName.hibernate_sequence which is a table, for sequence based id generation.

When you use GenerationType.SEQUENCE as the strategy you need to provide the @TableGenerator as follows.

     @Id
     @GeneratedValue(strategy = GenerationType.TABLE, generator = "user_table_generator")
     @TableGenerator(name = "user_table_generator",
                table = "user_keys", pkColumnName = "PK_NAME", valueColumnName = "PK_VALUE")
     @Column(name = "USER_ID")
     private long userId;

When you set the strategy it the to

@GeneratedValue(strategy = GenerationType.IDENTITY) .

original issue get resolved because then Hibernate stop looking for sequence table.

SQL Server doesn't have regular expressions. It uses the LIKE pattern matching syntax which isn't the same.

As it happens, you are close. Just need leading+trailing wildcards and move the NOT

 WHERE whatever NOT LIKE '%[a-z0-9]%'

In order to pass the parameters you create new intent and put a parameter map:

Intent myIntent = new Intent(this, NewActivityClassName.class);
myIntent.putExtra("firstKeyName","FirstKeyValue");
myIntent.putExtra("secondKeyName","SecondKeyValue");
startActivity(myIntent);

In order to get the parameters values inside the started activity, you must call the get[type]Extra() on the same intent:

// getIntent() is a method from the started activity
Intent myIntent = getIntent(); // gets the previously created intent
String firstKeyName = myIntent.getStringExtra("firstKeyName"); // will return "FirstKeyValue"
String secondKeyName= myIntent.getStringExtra("secondKeyName"); // will return "SecondKeyValue"

If your parameters are ints you would use getIntExtra() instead etc. Now you can use your parameters like you normally would.

Here is a bash script that combines the ideas and idioms of several previous comments to provide, with examples, inline comments having the general form ${__+ <comment text>}.

In particular

• <comment text> can be multi-line
• <comment text> is not parameter-expanded
• no subprocesses are spawned (so comments are efficient)

There is one restriction on the <comment text>, namely, unbalanced braces '}' and parentheses ')' must be protected (i.e., '\}' and '\)').

There is one requirement on the local bash environment:

• the parameter name __ must be unset

Any other syntactically valid bash parameter-name will serve in place of __, provided that the name has no set value.

An example script follows

# provide bash inline comments having the form
#     <code> ${__+ <comment>} <code> 
#     <code> ${__+ <multiline
#                   comment>} <code>

# utility routines that obviate "useless use of cat"
function bashcat { printf '%s\n' "$(</dev/stdin)"; }
function scat { 1>&2 bashcat; exit 1; }

# ensure that '__' is unset && remains unset
[[ -z ${__+x} ]] &&  # if '__' is unset
  declare -r __ ||   # then ensure that '__' remains unset 
  scat <<EOF         # else exit with an error
Error: the parameter __='${__}' is set, hence the
  comment-idiom '\${__+ <comment text>}' will fail
EOF

${__+ (example of inline comments)
------------------------------------------------
the following inline comment-idiom is supported
    <code> ${__+ <comment>} <code> 
    <code> ${__+ <multiline
                  comment>} <code> 
(advisory) the parameter '__' must NOT be set;
  even the null declaration __='' will fail
(advisory) protect unbalanced delimiters \} and \) 
(advisory) NO parameter-expansion of <comment> 
(advisory) NO subprocesses are spawned
(advisory) a functionally equivalent idiom is 
    <code> `# <comment>` <code> 
    <code> `# <multiline
               comment>` <code>
however each comment spawns a bash subprocess
that inelegantly requires ~1ms of computation 
------------------------------------------------}

If temp_rst1.BOF and temp_rst1.EOF then the recordset is empty. This will always be true for an empty recordset, linked or local.

The answer below is taken from Reading from Console: JAVA Scanner vs BufferedReader

When read an input from console, there are two options exists to achieve that. First using Scanner, another using BufferedReader. Both of them have different characteristics. It means differences how to use it.

Scanner treated given input as token. BufferedReader just read line by line given input as string. Scanner it self provide parsing capabilities just like nextInt(), nextFloat().

But, what is others differences between?

• Scanner treated given input as token. BufferedReader as stream line/String
• Scanner tokenized given input using regex. Using BufferedReader must write extra code
• BufferedReader faster than Scanner *point no. 2
• Scanner isn’t synchronized, BufferedReader synchronized

Scanner come with since JDK version 1.5 higher.

When should use Scanner, or Buffered Reader?

Look at the main differences between both of them, one using tokenized, others using stream line. When you need parsing capabilities, use Scanner instead. But, i am more comfortable with BufferedReader. When you need to read from a File, use BufferedReader, because it’s use buffer when read a file. Or you can use BufferedReader as input to Scanner.

The default for ResultSet.getInt when the field value is NULL is to return 0, which is also the default value for your iVal declaration. In which case your test is completely redundant.

If you actually want to do something different if the field value is NULL, I suggest:

int iVal = 0;
ResultSet rs = magicallyAppearingStmt.executeQuery(query);
if (rs.next()) {
    iVal = rs.getInt("ID_PARENT");
    if (rs.wasNull()) {
        // handle NULL field value
    }
}

(Edited as @martin comments below; the OP code as written would not compile because iVal is not initialised)

Your calculations are still based on a number of CSS pixels. They're just a different size on the screen now. That's the point of full page zoom.

What would you want to happen on a browser on a 192dpi device which therefore normally displayed four device pixels for each pixel in an image? At 50% zoom this device now displays one image pixel in one device pixel.

Internet Explorer doesn't fully support Flexbox due to:

Partial support is due to large amount of bugs present (see known issues).

_{Screenshot and infos taken from caniuse.com}

Notes

Internet Explorer before 10 doesn't support Flexbox, while IE 11 only supports the 2012 syntax.

Known issues

• IE 11 requires a unit to be added to the third argument, the flex-basis property see MSFT documentation.
• In IE10 and IE11, containers with display: flex and flex-direction: column will not properly calculate their flexed childrens' sizes if the container has min-height but no explicit height property. See bug.
• In IE10 the default value for flex is 0 0 auto rather than 0 1 auto as defined in the latest spec.
• IE 11 does not vertically align items correctly when min-height is used. See bug.

Workarounds

Flexbugs is a community-curated list of Flexbox issues and cross-browser workarounds for them. Here's a list of all the bugs with a workaround available and the browsers that affect.

1. Minimum content sizing of flex items not honored
2. Column flex items set to align-items: center overflow their container
3. min-height on a flex container won't apply to its flex items
4. flex shorthand declarations with unitless flex-basis values are ignored
5. Column flex items don't always preserve intrinsic aspect ratios
6. The default flex value has changed
7. flex-basis doesn't account for box-sizing: border-box
8. flex-basis doesn't support calc()
9. Some HTML elements can't be flex containers
10. align-items: baseline doesn't work with nested flex containers
11. Min and max size declarations are ignored when wrapping flex items
12. Inline elements are not treated as flex-items
13. Importance is ignored on flex-basis when using flex shorthand
14. Shrink-to-fit containers with flex-flow: column wrap do not contain their items
15. Column flex items ignore margin: auto on the cross axis
16. flex-basis cannot be animated
17. Flex items are not correctly justified when max-width is used

You are modifying the list book_shop.values()[i], which is not getting updated in the dictionary. Whenever you call the values() method, it will give you the values available in dictionary, and here you are not modifying the data of the dictionary.

I took the idiot route. Added these to the end of /etc/profile

for environment in `find /etc/environments.d -type f`
do
     . $environment
done

created a folder /etc/environments create a file in it called "oracle" or "whatever" and added the stuff I needed set globally to it.

/etc$ cat /etc/environments.d/Oracle

If it ever came up in an interview and you were told you can't use Array.Reverse, i think this might be one of the fastest. It does not create new strings and iterates only over half of the array (i.e O(n/2) iterations)

    public static string ReverseString(string stringToReverse)
    {
        char[] charArray = stringToReverse.ToCharArray();
        int len = charArray.Length-1;
        int mid = len / 2;

        for (int i = 0; i < mid; i++)
        {
            char tmp = charArray[i];
            charArray[i] = charArray[len - i];
            charArray[len - i] = tmp;
        }
        return new string(charArray);
    }

$.browser was removed from jQuery starting with version 1.9. It is now available as a plugin. It's generally recommended to avoid browser detection, which is why it was removed.

You wrote """I assume that means the HTML contains some wrongly-formed attempt at unicode somewhere."""

The HTML is NOT expected to contain any kind of "attempt at unicode", well-formed or not. It must of necessity contain Unicode characters encoded in some encoding, which is usually supplied up front ... look for "charset".

You appear to be assuming that the charset is UTF-8 ... on what grounds? The "\xA0" byte that is shown in your error message indicates that you may have a single-byte charset e.g. cp1252.

If you can't get any sense out of the declaration at the start of the HTML, try using chardet to find out what the likely encoding is.

Why have you tagged your question with "regex"?

Update after you replaced your whole question with a non-question:

html = urllib.urlopen(link).read()
# html refers to a str object. To get unicode, you need to find out
# how it is encoded, and decode it.

html.encode("utf8","ignore")
# problem 1: will fail because html is a str object;
# encode works on unicode objects so Python tries to decode it using 
# 'ascii' and fails
# problem 2: even if it worked, the result will be ignored; it doesn't 
# update html in situ, it returns a function result.
# problem 3: "ignore" with UTF-n: any valid unicode object 
# should be encodable in UTF-n; error implies end of the world,
# don't try to ignore it. Don't just whack in "ignore" willy-nilly,
# put it in only with a comment explaining your very cogent reasons for doing so.
# "ignore" with most other encodings: error implies that you are mistaken
# in your choice of encoding -- same advice as for UTF-n :-)
# "ignore" with decode latin1 aka iso-8859-1: error implies end of the world.
# Irrespective of error or not, you are probably mistaken
# (needing e.g. cp1252 or even cp850 instead) ;-)

This function will do as JohnFx suggested and allow for varied lengths on the arrays

Function mergeArrays(ByVal arr1 As Variant, ByVal arr2 As Variant) As Variant
    Dim holdarr As Variant
    Dim ub1 As Long
    Dim ub2 As Long
    Dim bi As Long
    Dim i As Long
    Dim newind As Long

        ub1 = UBound(arr1) + 1
        ub2 = UBound(arr2) + 1

        bi = IIf(ub1 >= ub2, ub1, ub2)

        ReDim holdarr(ub1 + ub2 - 1)

        For i = 0 To bi
            If i < ub1 Then
                holdarr(newind) = arr1(i)
                newind = newind + 1
            End If

            If i < ub2 Then
                holdarr(newind) = arr2(i)
                newind = newind + 1
            End If
        Next i

        mergeArrays = holdarr
End Function

I modified @Thierry Templier's response so the pipe can sort custom objects in angular 4:

import { Pipe, PipeTransform } from "@angular/core";

@Pipe({
  name: "sort"
})
export class ArraySortPipe  implements PipeTransform {
  transform(array: any, field: string): any[] {
    if (!Array.isArray(array)) {
      return;
    }
    array.sort((a: any, b: any) => {
      if (a[field] < b[field]) {
        return -1;
      } else if (a[field] > b[field]) {
        return 1;
      } else {
        return 0;
      }
    });
    return array;
  }
}

And to use it:

*ngFor="let myObj of myArr | sort:'fieldName'"

Hopefully this helps someone.

The first method cannot be used to create dynamic 2D arrays because by doing:

int *board[4];

you essentially allocated an array of 4 pointers to int on stack. Therefore, if you now populate each of these 4 pointers with a dynamic array:

for (int i = 0; i < 4; ++i) {
  board[i] = new int[10];
}

what you end-up with is a 2D array with static number of rows (in this case 4) and dynamic number of columns (in this case 10). So it is not fully dynamic because when you allocate an array on stack you should specify a constant size, i.e. known at compile-time. Dynamic array is called dynamic because its size is not necessary to be known at compile-time, but can rather be determined by some variable in runtime.

Once again, when you do:

int *board[4];

or:

const int x = 4; // <--- `const` qualifier is absolutely needed in this case!
int *board[x];

you supply a constant known at compile-time (in this case 4 or x) so that compiler can now pre-allocate this memory for your array, and when your program is loaded into the memory it would already have this amount of memory for the board array, that's why it is called static, i.e. because the size is hard-coded and cannot be changed dynamically (in runtime).

On the other hand, when you do:

int **board;
board = new int*[10];

or:

int x = 10; // <--- Notice that it does not have to be `const` anymore!
int **board;
board = new int*[x];

the compiler does not know how much memory board array will require, and therefore it does not pre-allocate anything. But when you start your program, the size of array would be determined by the value of x variable (in runtime) and the corresponding space for board array would be allocated on so-called heap - the area of memory where all programs running on your computer can allocate unknown beforehand (at compile-time) amounts memory for personal usage.

As a result, to truly create dynamic 2D array you have to go with the second method:

int **board;
board = new int*[10]; // dynamic array (size 10) of pointers to int

for (int i = 0; i < 10; ++i) {
  board[i] = new int[10];
  // each i-th pointer is now pointing to dynamic array (size 10) of actual int values
}

We've just created an square 2D array with 10 by 10 dimensions. To traverse it and populate it with actual values, for example 1, we could use nested loops:

for (int i = 0; i < 10; ++i) {   // for each row
  for (int j = 0; j < 10; ++j) { // for each column
    board[i][j] = 1;
  }
}

Use codecs if possible,

with codecs.open('file_path', 'a+', 'utf-8') as fp:
    fp.write(json.dumps(res, ensure_ascii=False))

nzd$date <- format(as.Date(nzd$date), "%Y/%m/%d")

In the above piece of code, there are two mistakes. First of all, when you are reading nzd$date inside as.Date you are not mentioning in what format you are feeding it the date. So, it tries it's default set format to read it. If you see the help doc, ?as.Date you will see

format
A character string. If not specified, it will try "%Y-%m-%d" then "%Y/%m/%d" on the first non-NA element, and give an error if neither works. Otherwise, the processing is via strptime

The second mistake is: even though you would like to read it in %Y-%m-%d format, inside format you wrote "%Y/%m/%d".

Now, the correct way of doing it is:

> nzd <- data.frame(date=c("31/08/2011", "31/07/2011", "30/06/2011"), 
+                                       mid=c(0.8378,0.8457,0.8147))
> nzd
        date    mid
1 31/08/2011 0.8378
2 31/07/2011 0.8457
3 30/06/2011 0.8147
> nzd$date <- format(as.Date(nzd$date, format = "%d/%m/%Y"), "%Y-%m-%d")
> head(nzd)
        date    mid
1 2011-08-31 0.8378
2 2011-07-31 0.8457
3 2011-06-30 0.8147

As Ben said, you'll need to work with the UIView's layer, using a CATransform3D to perform the layer's rotation. The trick to get perspective working, as described here, is to directly access one of the matrix cells of the CATransform3D (m34). Matrix math has never been my thing, so I can't explain exactly why this works, but it does. You'll need to set this value to a negative fraction for your initial transform, then apply your layer rotation transforms to that. You should also be able to do the following:

Objective-C

UIView *myView = [[self subviews] objectAtIndex:0];
CALayer *layer = myView.layer;
CATransform3D rotationAndPerspectiveTransform = CATransform3DIdentity;
rotationAndPerspectiveTransform.m34 = 1.0 / -500;
rotationAndPerspectiveTransform = CATransform3DRotate(rotationAndPerspectiveTransform, 45.0f * M_PI / 180.0f, 0.0f, 1.0f, 0.0f);
layer.transform = rotationAndPerspectiveTransform;

Swift 5.0

if let myView = self.subviews.first {
    let layer = myView.layer
    var rotationAndPerspectiveTransform = CATransform3DIdentity
    rotationAndPerspectiveTransform.m34 = 1.0 / -500
    rotationAndPerspectiveTransform = CATransform3DRotate(rotationAndPerspectiveTransform, 45.0 * .pi / 180.0, 0.0, 1.0, 0.0)
    layer.transform = rotationAndPerspectiveTransform
}

which rebuilds the layer transform from scratch for each rotation.

A full example of this (with code) can be found here, where I've implemented touch-based rotation and scaling on a couple of CALayers, based on an example by Bill Dudney. The newest version of the program, at the very bottom of the page, implements this kind of perspective operation. The code should be reasonably simple to read.

The sublayerTransform you refer to in your response is a transform that is applied to the sublayers of your UIView's CALayer. If you don't have any sublayers, don't worry about it. I use the sublayerTransform in my example simply because there are two CALayers contained within the one layer that I'm rotating.

Chrome can run as root (remember to use gksu when doing so) so long as you provide it with a profile directory.

Rather than type in the profile directory every time you want to run it, create a new bash file (I'd name it something like start-chrome.sh)

#/bin/bash
google-chrome --user-data-dir="/root/chrome-profile/"

Rember to call that script with root privelages!

$ gksu /root/start-chrome.sh

Do you want to match a class exactly, e.g. only matching FileInputStream instead of any subclass of FileInputStream? If so, use getClass() and ==. I would typically do this in an equals, so that an instance of X isn't deemed equal to an instance of a subclass of X - otherwise you can get into tricky symmetry problems. On the other hand, that's more usually useful for comparing that two objects are of the same class than of one specific class.

Otherwise, use instanceof. Note that with getClass() you will need to ensure you have a non-null reference to start with, or you'll get a NullPointerException, whereas instanceof will just return false if the first operand is null.

Personally I'd say instanceof is more idiomatic - but using either of them extensively is a design smell in most cases.

There is a ToArray() function on Values:

Foo[] arr = new Foo[dict.Count];    
dict.Values.CopyTo(arr, 0);

But I don't think its efficient (I haven't really tried, but I guess it copies all these values to the array). Do you really need an Array? If not, I would try to pass IEnumerable:

IEnumerable<Foo> foos = dict.Values;

I am using python 3 in windows. I also faced this issue. I just uninstalled 'mysqlclient' and then installed it again. It worked somehow

Collected ideas from multiple C++ sources and put it into a nice, still quite simple example for getters/setters in C++:

class Canvas { public:
    void resize() {
        cout << "resize to " << width << " " << height << endl;
    }

    Canvas(int w, int h) : width(*this), height(*this) {
        cout << "new canvas " << w << " " << h << endl;
        width.value = w;
        height.value = h;
    }

    class Width { public:
        Canvas& canvas;
        int value;
        Width(Canvas& canvas): canvas(canvas) {}
        int & operator = (const int &i) {
            value = i;
            canvas.resize();
            return value;
        }
        operator int () const {
            return value;
        }
    } width;

    class Height { public:
        Canvas& canvas;
        int value;
        Height(Canvas& canvas): canvas(canvas) {}
        int & operator = (const int &i) {
            value = i;
            canvas.resize();
            return value;
        }
        operator int () const {

    } height;
};

int main() {
    Canvas canvas(256, 256);
    canvas.width = 128;

resize to 128 256
resize to 128 64

I was getting the same error and used below below link to get help:

https://nodejs.org/api/http.html#http_http_request_options_callback

I was not having in my code:

req.end();

(NodeJs V: 5.4.0) once added above req.end(); line, I was able to get rid of the error and worked fine for me.

You can do it like the other people before me told you using a look:

A.) Use .data of the button element to share a look variable (or a just global variable)

if ($('#buttonId').data('locked') == 1)
    return
$('#buttonId').data('locked') = 1;
// Do your thing
$('#buttonId').data('locked') = 0;

B.) Disable mouse signals

$("#buttonId").css("pointer-events", "none");
// Do your thing
$("#buttonId").css("pointer-events", "auto");

C.) If it is a HTML button you can disable it (input [type=submit] or button)

$("#buttonId").attr("disabled", "true");
// Do your thing
$("#buttonId").attr("disabled", "false");

But watch out for other threads! I failed many times because my animation (fading in or out) took one second. E.g. fadeIn/fadeOut supports a callback function as second parameter. If there is no other way just do it using setTimeout(callback, delay).

Greets, Thomas

Your selector is a little off, it's missing the trailing ]

var mySelect = $('select[name=' + name + ']')

you may also need to put quotes around the name, like so:

var mySelect = $('select[name="' + name + '"]')

Add the below line

this.Configuration.ProxyCreationEnabled = false;

Two way to use ProxyCreationEnabled as false.

1. Add it inside of DBContext Constructor

   public ProductEntities() : base("name=ProductEntities")
   {
       this.Configuration.ProxyCreationEnabled = false;
   }
   

OR

2. Add the line inside of Get method

   public IEnumerable<Brand_Details> Get()
   {
       using (ProductEntities obj = new ProductEntities())
       {
           this.Configuration.ProxyCreationEnabled = false;
           return obj.Brand_Details.ToList();
       }
   }
   

 $(document).ready(function() {

     var CookieSet = $.cookie('cookietitle', 'yourvalue');

     if (CookieSet == null) {
          // Do Nothing
     }
     if (jQuery.cookie('cookietitle')) {
          // Reactions
     }
 });

#include <stdio.h>
int main()
{
    char a[5],b[10];
    scanf("%2000s %2000[^\n]s",a,b);
    printf("a=%s b=%s",a,b);
}

Just write s in place of \n :)

I'd suggest attaching listeners to key events fired by the editable element, though you need to be aware that keydown and keypress events are fired before the content itself is changed. This won't cover every possible means of changing the content: the user can also use cut, copy and paste from the Edit or context browser menus, so you may want to handle the cut copy and paste events too. Also, the user can drop text or other content, so there are more events there (mouseup, for example). You may want to poll the element's contents as a fallback.

UPDATE 29 October 2014

The HTML5 input event is the answer in the long term. At the time of writing, it is supported for contenteditable elements in current Mozilla (from Firefox 14) and WebKit/Blink browsers, but not IE.

Demo:

document.getElementById("editor").addEventListener("input", function() {_x000D_
    console.log("input event fired");_x000D_
}, false);

<div contenteditable="true" id="editor">Please type something in here</div>

I encountered this error when trying to set up NuGet packages inside locally hosted Gitlab instance. The error indicated 401 Unauthorized code. The solution was removing offending source with:

nuget source Remove -Name SOURCE_NAME

And then adding the same source, but this time specifying the username and password in the command:

nuget source Add -Name SOURCE_NAME -Source SOURCE_URL -UserName GITLAB_DEPLOY_TOKEN_USERNAME -Password GITLAB_DEPLOY_TOKEN

$ cat x.mak
all:
    echo $(OPTION)
$ make -f x.mak 'OPTION=-DPASSTOC=42'
echo -DPASSTOC=42
-DPASSTOC=42

I had a similar issue with mongoose :

fields: 
    [ '[object Object]',
     '[object Object]',
     '[object Object]',
     '[object Object]' ] }

In fact, I was using "type" as a property name in my schema :

fields: [
    {
      name: String,
      type: {
        type: String
      },
      registrationEnabled: Boolean,
      checkinEnabled: Boolean
    }
  ]

To avoid that behavior, you have to change the parameter to :

fields: [
    {
      name: String,
      type: {
        type: { type: String }
      },
      registrationEnabled: Boolean,
      checkinEnabled: Boolean
    }
  ]

You should be referencing Selected not ids.Contains as the last line.

I just realized this is a formatting issue, from the OP. Regardless you should be referencing the value in Selected. I recommend adding some Console.WriteLine calls to see exactly what is being printed out on each line and also what each value is.

After your update: ids is an empty list, how is this not throwing a NullReferenceException? As it was never initialized in that code block

Date now= new Date();
// Today midnight
Date todayMidnight = new Date(endTime.getTime() -endTime.getTime()%DateUtils.MILLIS_PER_DAY);

// tomorrow midnight
Date tomorrowMidnight = new Date(endTime.getTime() -endTime.getTime()%DateUtils.MILLIS_PER_DAY + DateUtils.MILLIS_PER_DAY);

You must wrap the returning object literal into parentheses. Otherwise curly braces will be considered to denote the function’s body. The following works:

p => ({ foo: 'bar' });

You don't need to wrap any other expression into parentheses:

p => 10;
p => 'foo';
p => true;
p => [1,2,3];
p => null;
p => /^foo$/;

and so on.

Reference: MDN - Returning object literals

If the question is: "Is it possible to add value on ESC" than the answer is yes. You can do something like that. For example with use of jQuery it would look like below.

HTML

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>

<input type="text" value="default!" id="myInput" />

JavaScript

$(document).ready(function (){
    $('#myInput').keyup(function(event) {
        // 27 is key code of ESC
        if (event.keyCode == 27) {
            $('#myInput').val('default!');
            // Loose focus on input field
            $('#myInput').blur();
        }
    });
});

Starting with Spring Boot 1.2, you can configure SSL using application.properties or application.yml. Here's an example for application.properties:

server.port = 8443
server.ssl.key-store = classpath:keystore.jks
server.ssl.key-store-password = secret
server.ssl.key-password = another-secret

Same thing with application.yml:

server:
  port: 8443
  ssl:
    key-store: classpath:keystore.jks
    key-store-password: secret
    key-password: another-secret

Here's a link to the current reference documentation.

Given this .env file:

DB_NAME=foo
DB_USER=bar
DB_PASSWORD=baz

And this mongo-init.sh file:

mongo --eval "db.auth('$MONGO_INITDB_ROOT_USERNAME', '$MONGO_INITDB_ROOT_PASSWORD'); db = db.getSiblingDB('$DB_NAME'); db.createUser({ user: '$DB_USER', pwd: '$DB_PASSWORD', roles: [{ role: 'readWrite', db: '$DB_NAME' }] });"

This docker-compose.yml will create the admin database and admin user, authenticate as the admin user, then create the real database and add the real user:

version: '3'

services:
#  app:
#    build: .
#    env_file: .env
#    environment:
#      DB_HOST: 'mongodb://mongodb'

  mongodb:
    image: mongo:4
    environment:
      MONGO_INITDB_ROOT_USERNAME: admin-user
      MONGO_INITDB_ROOT_PASSWORD: admin-password
      DB_NAME: $DB_NAME
      DB_USER: $DB_USER
      DB_PASSWORD: $DB_PASSWORD
    ports:
      - 27017:27017
    volumes:
      - db-data:/data/db
      - ./mongo-init.sh:/docker-entrypoint-initdb.d/mongo-init.sh

This query will get you all the tables in the database

USE [DatabaseName];

SELECT * FROM information_schema.tables;

use doesn't include anything. It just imports the specified namespace (or class) to the current scope

If you want the classes to be autoloaded - read about autoloading

If you want to do it by ClassName you could do:

<script type="text/javascript">
function hideTd(className){
    var elements;

    if (document.getElementsByClassName)
    {
        elements = document.getElementsByClassName(className);
    }
    else
    {
        var elArray = [];
        var tmp = document.getElementsByTagName(elements);  
        var regex = new RegExp("(^|\\s)" + className+ "(\\s|$)");
        for ( var i = 0; i < tmp.length; i++ ) {

            if ( regex.test(tmp[i].className) ) {
                elArray.push(tmp[i]);
            }
        }

        elements = elArray;
    }

    for(var i = 0, i < elements.length; i++) {
       if( elements[i].textContent == ''){
          elements[i].style.display = 'none';
       } 
    }

  }
</script>

The expression between the <%= %> is evaluated before the c:if tag is evaluated. So, supposing that |request.isUserInRole| returns |true|, your example would be evaluated to this first:

<c:if test="true">
    <li>user</li>
</c:if>

and then the c:if tag would be executed.

If you've opened a table and you want to clear an existing value to NULL, click on the value, and press Ctrl+0.

Here is a Swift way to get screen sizes:

print(screenWidth)
print(screenHeight)

var screenWidth: CGFloat {
    if UIInterfaceOrientationIsPortrait(screenOrientation) {
        return UIScreen.mainScreen().bounds.size.width
    } else {
        return UIScreen.mainScreen().bounds.size.height
    }
}

var screenHeight: CGFloat {
    if UIInterfaceOrientationIsPortrait(screenOrientation) {
        return UIScreen.mainScreen().bounds.size.height
    } else {
        return UIScreen.mainScreen().bounds.size.width
    }
}

var screenOrientation: UIInterfaceOrientation {
    return UIApplication.sharedApplication().statusBarOrientation
}

These are included as a standard function in:

https://github.com/goktugyil/EZSwiftExtensions

Use a combination of of fopen, fwrite and fread. PHP.net has excellent documentation and examples of each of them.

http://us2.php.net/manual/en/function.fopen.php
http://us2.php.net/manual/en/function.fwrite.php
http://us2.php.net/manual/en/function.fread.php

I know is late but you can quickly accomplish that by just typing Ctrl + Shift + p and then type default, it will show an option that says

Terminal: Select Default Shell

, it will then display all the terminals available to you.

Basically, these events act differently on different browser type and version, I created a little jsBin test and you can check the console for find out how these events behavior for your targeted environment, hope this help. http://jsbin.com/zipivadu/10/edit

In order to not waste space in the terminal with special characters to pieces of information, you can differentiate information using multiple colors.

Eg. in order to get this desired effect:

You can do the following to your prompt:

PROMPT='%F{magenta}${PWD/#$HOME/~} %F{green}${vcs_info_msg_0_} %F{cyan}$%F{reset_color} '

The way it works is every time you set a color using $F{myColor} the color from that point onward will stick to that. It's important to add in %{reset_color} at the end so that the input text goes back to the original color (or you could set it to something else if you'd like).

If you have the test binary installed or ksh has a matching built-in function, you could use it to perform your checks. Usually /bin/[ is a symbolic link to test:

if [ -e "$file_name" ]; then
  echo "File exists"
fi

if [ -z "$used_var" ]; then
  echo "Variable is empty"
fi

In the case of Windows 10 this is not exactly accurate, in fact none of the answers on stackoverflow was, I found this out when I tried to use pixel art as an icon and it got rescaled when it was not supposed to(it was easy to see in this case cause of the interpolation and smoothing windows does) even thou I used the sizes from this post.

So I made an app and did the work on all DPI settings, see it here:
Windows 10 all icon resolutions on all DPI settings
You can also use my app to create icons, also with nearest neighbor interpolation with smoothing off, which is not done with any of the bad editors I have seen.

If you only want the resolutions:
16, 20, 24, 28, 30, 31, 32, 40, 42, 47, 48, 56, 60, 63, 84, 256
and you should use all PNG icons and anything you put in beside these it won't be displayed. See my post why.

I had the same problem. Adding include path does work for all except std::string.

I noticed in the mingw-Toolchain many system header files *.tcc

I added filetype *.tcc as "C++ Header File" in Preferences > C/C++/ File Types. Now std::string can be resolved from the internal index and Code Analyzer. Perhaps this is added to Eclipse CDT by default in feature.

I hope this helps to someone...

import pandas as pd
import numpy as np

df = pd.DataFrame({'ItemQty': {0: 3, 1: 25}, 
                   'Seatblocks': {0: '2:218:10:4,6', 1: '1:13:36:1,12 1:13:37:1,13'}, 
                   'ItemExt': {0: 60, 1: 300}, 
                   'CustomerName': {0: 'McCartney, Paul', 1: 'Lennon, John'}, 
                   'CustNum': {0: 32363, 1: 31316}, 
                   'Item': {0: 'F04', 1: 'F01'}}, 
                    columns=['CustNum','CustomerName','ItemQty','Item','Seatblocks','ItemExt'])

print (df)
   CustNum     CustomerName  ItemQty Item                 Seatblocks  ItemExt
0    32363  McCartney, Paul        3  F04               2:218:10:4,6       60

Another similar solution with chaining is use reset_index and rename:

print (df.drop('Seatblocks', axis=1)
             .join
             (
             df.Seatblocks
             .str
             .split(expand=True)
             .stack()
             .reset_index(drop=True, level=1)
             .rename('Seatblocks')           
             ))

   CustNum     CustomerName  ItemQty Item  ItemExt    Seatblocks
0    32363  McCartney, Paul        3  F04       60  2:218:10:4,6
1    31316     Lennon, John       25  F01      300  1:13:36:1,12
1    31316     Lennon, John       25  F01      300  1:13:37:1,13

If in column are NOT NaN values, the fastest solution is use list comprehension with DataFrame constructor:

df = pd.DataFrame(['a b c']*100000, columns=['col'])

In [141]: %timeit (pd.DataFrame(dict(zip(range(3), [df['col'].apply(lambda x : x.split(' ')[i]) for i in range(3)]))))
1 loop, best of 3: 211 ms per loop

In [142]: %timeit (pd.DataFrame(df.col.str.split().tolist()))
10 loops, best of 3: 87.8 ms per loop

In [143]: %timeit (pd.DataFrame(list(df.col.str.split())))
10 loops, best of 3: 86.1 ms per loop

In [144]: %timeit (df.col.str.split(expand=True))
10 loops, best of 3: 156 ms per loop

In [145]: %timeit (pd.DataFrame([ x.split() for x in df['col'].tolist()]))
10 loops, best of 3: 54.1 ms per loop

But if column contains NaN only works str.split with parameter expand=True which return DataFrame (documentation), and it explain why it is slowier:

df = pd.DataFrame(['a b c']*10, columns=['col'])
df.loc[0] = np.nan
print (df.head())
     col
0    NaN
1  a b c
2  a b c
3  a b c
4  a b c

print (df.col.str.split(expand=True))
     0     1     2
0  NaN  None  None
1    a     b     c
2    a     b     c
3    a     b     c
4    a     b     c
5    a     b     c
6    a     b     c
7    a     b     c
8    a     b     c
9    a     b     c

in your css file do img { float: left; } and h1 {float: left; }

Any of the following should work!!

df <- data.frame(x=1:3,y=4:6)

mean(df$x)
mean(df[,1])
mean(df[["x"]])

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

git checkout -b my_new_branch
git commit

Checking out the new branch will not discard your changes.

In my case (OS X) it was because I have set GOPATH to /home/username/go (as per the book) instead of /Users/username/go

If you're on Linux/Unix you could avoid call() altogether and not execute an entirely new instance of the Python executable and its environment.

import os

cpid = os.fork()
if not cpid:
    import somescript
    os._exit(0)

os.waitpid(cpid, 0)

For what it's worth.

var string ='my string'
var new_string = string.replace('string','new string');
alert(string);
alert(new_string);

set nocount on

the quotes are there, use -w2000 to keep each row on one line.

It means you're passing the variable by reference.

In fact, in a declaration of a type, it means reference, just like:

int x = 42;
int& y = x;

declares a reference to x, called y.

To link to a UNC path from an HTML document, use file:///// (yes, that's five slashes).

file://///server/path/to/file.txt

Note that this is most useful in IE and Outlook/Word. It won't work in Chrome or Firefox, intentionally - the link will fail silently. Some words from the Mozilla team:

For security purposes, Mozilla applications block links to local files (and directories) from remote files.

And less directly, from Google:

Firefox and Chrome doesn't open "file://" links from pages that originated from outside the local machine. This is a design decision made by those browsers to improve security.

The Mozilla article includes a set of client settings you can use to override this behavior in Firefox, and there are extensions for both browsers to override this restriction.

<p>Please click in the following {{link}} to verify the account</p>

function renderHTML(templatePath: string, object) {
    const template = fileSystem.readFileSync(path.join(Application.staticDirectory, templatePath + '.html'), 'utf8');
    return template.match(/\{{(.*?)\}}/ig).reduce((acc, binding) => {
        const property = binding.substring(2, binding.length - 2);
        return `${acc}${template.replace(/\{{(.*?)\}}/, object[property])}`;
    }, '');
}

renderHTML(templateName, { link: 'SomeLink' })

for sure you can improve the reading template function to read as stream and compose the bytes by line to make it more efficient

As for me, most elegant way is yield break

The second way isn't valid XML; did you mean <numbers>[3,2,1]</numbers>?

If so, then the first one is preferred because all you need to get the array elements is some XML manipulation. On the second one you first need to get the value of the <numbers> element via XML manipulation, then somehow parse the [3,2,1] text using something else.

Or if you really want some compact format, you can consider using JSON (which "natively" supports arrays). But that depends on your application requirements.

It selects all elements where the class name contains the string "span" somewhere. There's also ^= for the beginning of a string, and $= for the end of a string. Here's a good reference for some CSS selectors.

I'm only familiar with the bootstrap classes spanX where X is an integer, but if there were other selectors that ended in span, it would also fall under these rules.

It just helps to apply blanket CSS rules.

It somewhat depends on what you use as a CGI framework, but they are available in dictionaries accessible to the program. I'd point you to the docs, but I'm not getting through to python.org right now. But this note on mail.python.org will give you a first pointer. Look at the CGI and URLLIB Python libs for more.

Update

Okay, that link busted. Here's the basic wsgi ref

What about:

//true if it doesn't contain letters
bool result = hello.Any(x => !char.IsLetter(x));

Please try this

    <input type="button" value="Home" class="homebutton" id="btnHome" onClick="Javascript:window.location.href = 'http://www.website.com/index.php';" />

window.location.href example:

 window.location.href = 'http://www.google.com'; //Will take you to Google.

window.open() example:

     window.open('http://www.google.com'); //This will open Google in a new window.

You can use CSS3 transitions or maybe CSS3 animations to slide in an element.

For browser support: http://caniuse.com/

I made two quick examples just to show you how I mean.

CSS transition (on hover)

Demo One

Relevant Code

.wrapper:hover #slide {
    transition: 1s;
    left: 0;
}

In this case, Im just transitioning the position from left: -100px; to 0; with a 1s. duration. It's also possible to move the element using transform: translate();

CSS animation

Demo Two

#slide {
    position: absolute;
    left: -100px;
    width: 100px;
    height: 100px;
    background: blue;
    -webkit-animation: slide 0.5s forwards;
    -webkit-animation-delay: 2s;
    animation: slide 0.5s forwards;
    animation-delay: 2s;
}

@-webkit-keyframes slide {
    100% { left: 0; }
}

@keyframes slide {
    100% { left: 0; }
}

Same principle as above (Demo One), but the animation starts automatically after 2s, and in this case I've set animation-fill-mode to forwards, which will persist the end state, keeping the div visible when the animation ends.

Like I said, two quick example to show you how it could be done.

Hope this helped.

In order to get a notification from the database I wrote a command line script using websocket to check for the latest updated timestamp every second. This ran as an infinite loop on the server. If there is a change all connected clients will can be sent a notification.

DateTime.ParseExact(input,"yyyyMMdd HH:mm",null);

assuming you meant to say that minutes followed the hours, not seconds - your example is a little confusing.

The ParseExact documentation details other overloads, in case you want to have the parse automatically convert to Universal Time or something like that.

As @Joel Coehoorn mentions, there's also the option of using TryParseExact, which will return a Boolean value indicating success or failure of the operation - I'm still on .Net 1.1, so I often forget this one.

If you need to parse other formats, you can check out the Standard DateTime Format Strings.

Use either of these depending how you want backslashes in the shell variables handled (avar is an awk variable, svar is a shell variable):

awk -v avar="$svar" '... avar ...' file
awk 'BEGIN{avar=ARGV[1];ARGV[1]=""}... avar ...' "$svar" file

See http://cfajohnson.com/shell/cus-faq-2.html#Q24 for details and other options. The first method above is almost always your best option and has the most obvious semantics.

I tried above all and end-up with few changes which I would like to share. Here's the code which works for me (find the attached screenshot):

<div class="input-group">
    <input type="text" class="form-control" placeholder="Search text">
    <span class="input-group-btn" style="width:0;">
        <button class="btn btn-default" type="button">Go!</button>
    </span>
</div>

If you want to see it working, just use below code in you editor:

<html>
    <head>
        <link type='text/css' rel='stylesheet' href='https://maxcdn.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css' />
    </head>
    <body>
        <div class="container body-content">
            <div class="form-horizontal">
              <div class="input-group">
                  <input type="text" class="form-control" placeholder="Search text">
                  <span class="input-group-btn" style="width:0;">
                      <button class="btn btn-default" type="button">Go!</button>
                  </span>
              </div>
            </div>
        </div>
    </body>
</html>

Hope this helps.

sed is a stream editor. I would say try man sed.If you didn't find this man page in your system refer this URL:

http://unixhelp.ed.ac.uk/CGI/man-cgi?sed

Use getattr if you have an attribute in string form:

>>> class User(object):
       name = 'John'

>>> u = User()
>>> param = 'name'
>>> getattr(u, param)
'John'

Otherwise use the dot .:

>>> class User(object):
       name = 'John'

>>> u = User()
>>> u.name
'John'

You can achieve the solution, by doing this:

JavaScript:

var myValue = document.getElementById("@(ViewBag.CC)").value;

or if you want to use jQuery, then:

jQuery

var myValue = $('#' + '@(ViewBag.CC)').val();

Add a background-color to the element and you will nicely see the difference of inline vs. block, as explained by the other posters.

!important, after your CSS declaration.

div {
   color: blue !important; 

   /* This Is Now Working */
}

If you are using any layout page then, move script sections from bottom to head section in layout page. bcz, javascript files should be loaded first. This worked for me

Don't the height and font-size CSS properties work for you ?

If in case trigger("chosen:updated"); doesn't works for you. You can try $('#ddl').trigger('change'); as in my case its work for me.

I want to get the ASCII value of characters in a string in C#.

Everyone confer answer in this structure. If my string has the value "9quali52ty3", I want an array with the ASCII values of each of the 11 characters.

but in console we work frankness so we get a char and print the ASCII code if i wrong so please correct my answer.

 static void Main(string[] args)
        {
            Console.WriteLine(Console.Read());
            Convert.ToInt16(Console.Read());
            Console.ReadKey();
        }

add JAVA_HOME to the file:

/etc/environment

for it to be available to the entire system (you would need to restart Ubuntu though)

You would use regex for that in mongo.

e.g:

db.users.find({"name": /^m/})

I had the same issue of WebMvcConfigurerAdapter being deprecated. When I searched for examples, I hardly found any implemented code. Here is a piece of working code.

create a class that extends HandlerInterceptorAdapter

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;

import me.rajnarayanan.datatest.DataTestApplication;
@Component
public class EmployeeInterceptor extends HandlerInterceptorAdapter {
    private static final Logger logger = LoggerFactory.getLogger(DataTestApplication.class);
    @Override
    public boolean preHandle(HttpServletRequest request, 
            HttpServletResponse response, Object handler) throws Exception {

            String x = request.getMethod();
            logger.info(x + "intercepted");
        return true;
    }

}

then Implement WebMvcConfigurer interface

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

import me.rajnarayanan.datatest.interceptor.EmployeeInterceptor;
@Configuration
public class WebMvcConfig implements WebMvcConfigurer {
    @Autowired
    EmployeeInterceptor employeeInterceptor ;

    @Override
    public void addInterceptors(InterceptorRegistry registry){
        registry.addInterceptor(employeeInterceptor).addPathPatterns("/employee");
    }
}

Following solution is working fine.

HTML:

<table>
  <tr>
    <td>
      <input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this);">
    </td>
  </tr>
  <tr>
    <td>
      <input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this);">
    </td>
  </tr>
  <tr>
    <td>
      <input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this);">
    </td>
  </tr>
</table>

JQuery:

function SomeDeleteRowFunction(btndel) {
    if (typeof(btndel) == "object") {
        $(btndel).closest("tr").remove();
    } else {
        return false;
    }
}

I have done bins on http://codebins.com/bin/4ldqpa9

I tried some of these solutions, but they didn't quite work (though they were very much on the right track!)

In the end my error was:

FATAL: password authentication failed for user

when I ran the following command: psql

So then I ran these two commands:

dropdb()
createdb()

NOTE: this will remove the db, but I didn't need it and for some reason I could no longer access pqsl, so I removed and recreated it. Then psql worked again.

I did this and now my app is working properly,

res.sendFile('your drive://your_subfolders//file.html');

Session class has been removed on SDK 4.0. The login magement is done through the class LoginManager. So:

mLoginManager = LoginManager.getInstance();
mLoginManager.logOut();

As the reference Upgrading to SDK 4.0 says:

Session Removed - AccessToken, LoginManager and CallbackManager classes supercede and replace functionality in the Session class.

The problem with Threading.Thread.SLeep(2000) is that it executes first in my VB.Net program. This

Imports VB = Microsoft.VisualBasic

Public Sub wait(ByVal seconds As Single)
    Static start As Single
    start = VB.Timer()
    Do While VB.Timer() < start + seconds
        System.Windows.Forms.Application.DoEvents()
    Loop
End Sub

worked flawlessly.

It is whatever it is configured to be on that particular web server. A web server could be configured to run .pl files with the php module and .aspx files with perl, although that would be silly. There are no scripts involved with most web servers, instead you'd have to look in your apache configuration files (or equivalent, if using different server software). If you have permission to edit the server config file, then you could make files ending in .do run as php, if that's what you're after.

You could also just put the first SELECT in a subquery. Since most optimizers will fold it into a constant anyway, there should not be a performance hit on this.

Incidentally, since you are using a predicate like this:

CONVERT(...) = CONVERT(...)

that predicate expression cannot be optimized properly or use indexes on the columns reference by the CONVERT() function.

Here is one way to make the original query somewhat better:

DECLARE @ooDate datetime
SELECT @ooDate = OO.Date FROM OLAP.OutageHours AS OO where OO.OutageID = 1

SELECT 
  COUNT(FF.HALID)
FROM
  Outages.FaultsInOutages AS OFIO 
  INNER JOIN Faults.Faults as FF ON 
    FF.HALID = OFIO.HALID 
WHERE
  FF.FaultDate >= @ooDate AND
  FF.FaultDate < DATEADD(day, 1, @ooDate) AND
  OFIO.OutageID = 1

This version could leverage in index that involved FaultDate, and achieves the same goal.

Here it is, rewritten to use a subquery to avoid the variable declaration and subsequent SELECT.

SELECT 
  COUNT(FF.HALID)
FROM
  Outages.FaultsInOutages AS OFIO 
  INNER JOIN Faults.Faults as FF ON 
    FF.HALID = OFIO.HALID 
WHERE
  CONVERT(varchar(10), FF.FaultDate, 126) = (SELECT CONVERT(varchar(10), OO.Date, 126) FROM OLAP.OutageHours AS OO where OO.OutageID = 1) AND
  OFIO.OutageID = 1

Note that this approach has the same index usage issue as the original, because of the use of CONVERT() on FF.FaultDate. This could be remedied by adding the subquery twice, but you would be better served with the variable approach in this case. This last version is only for demonstration.

Regards.

Bootstrap Version 3.x

As always, read Bootstrap's great documentation:

3.x Docs: https://getbootstrap.com/docs/3.3/css/#grid-nesting

Make sure the parent level row is inside of a .container element. Whenever you'd like to nest rows, just open up a new .row inside of your column.

Here's a simple layout to work from:

<div class="container">
    <div class="row">
        <div class="col-xs-6">
            <div class="big-box">image</div>
        </div>
        <div class="col-xs-6">
            <div class="row">
                <div class="col-xs-6"><div class="mini-box">1</div></div>
                <div class="col-xs-6"><div class="mini-box">2</div></div>
                <div class="col-xs-6"><div class="mini-box">3</div></div>
                <div class="col-xs-6"><div class="mini-box">4</div></div>
            </div>
        </div>
    </div>
</div>

Bootstrap Version 4.0

4.0 Docs: http://getbootstrap.com/docs/4.0/layout/grid/#nesting

Here's an updated version for 4.0, but you should really read the entire docs section on the grid so you understand how to leverage this powerful feature

<div class="container">
  <div class="row">
    <div class="col big-box">
      image
    </div>

    <div class="col">
      <div class="row">
        <div class="col mini-box">1</div>
        <div class="col mini-box">2</div>
      </div>
      <div class="row">
        <div class="col mini-box">3</div>
        <div class="col mini-box">4</div>
      </div>
    </div>

  </div>
</div>

Which will look like this (with a little bit of added styling):

Someone has already made a benchmark: jQuery document.createElement equivalent?

$(document.createElement('div')) is the big winner.

To answer the question. stringstream basically allows you to treat a string object like a stream, and use all stream functions and operators on it.

I saw it used mainly for the formatted output/input goodness.

One good example would be c++ implementation of converting number to stream object.

Possible example:

template <class T>
string num2str(const T& num, unsigned int prec = 12) {
    string ret;
    stringstream ss;
    ios_base::fmtflags ff = ss.flags();
    ff |= ios_base::floatfield;
    ff |= ios_base::fixed;
    ss.flags(ff);
    ss.precision(prec);
    ss << num;
    ret = ss.str();
    return ret;
};

Maybe it's a bit complicated but it is quite complex. You create stringstream object ss, modify its flags, put a number into it with operator<<, and extract it via str(). I guess that operator>> could be used.

Also in this example the string buffer is hidden and not used explicitly. But it would be too long of a post to write about every possible aspect and use-case.

Note: I probably stole it from someone on SO and refined, but I don't have original author noted.

You can use a method reference:

import static java.util.Comparator.*;
import static java.util.stream.Collectors.*;

Arrays.asList(files).stream()
    .filter(file -> isNameLikeBaseLine(file, baseLineFile.getName()))
    .sorted(comparing(File::lastModified).reversed())
    .skip(numOfNewestToLeave)
    .forEach(item -> item.delete());

In alternative of method reference you can use a lambda expression, so the argument of comparing become:

.sorted(comparing(file -> file.lastModified()).reversed());

It seems that you are mixing different Pythons here (Python 2.x vs. Python 3.x)... This is basically correct:

nb = input('Choose a number: ')

The problem is that it is only supported in Python 3. As @sharpner answered, for older versions of Python (2.x), you have to use the function raw_input:

nb = raw_input('Choose a number: ')

If you want to convert that to a number, then you should try:

number = int(nb)

... though you need to take into account that this can raise an exception:

try:
    number = int(nb)
except ValueError:
    print("Invalid number")

And if you want to print the number using formatting, in Python 3 str.format() is recommended:

print("Number: {0}\n".format(number))

Instead of:

print('Number %s \n' % (nb))

But both options (str.format() and %) do work in both Python 2.7 and Python 3.

if you are on ubuntu u can try these commands:

sudo apt install npm

npm install && npm run dev

Improving on Andru's idea, you can write a script which creates console functions if they don't exist:

if (!window.console) console = {};
console.log = console.log || function(){};
console.warn = console.warn || function(){};
console.error = console.error || function(){};
console.info = console.info || function(){};

Then, use any of the following:

console.log(...);
console.error(...);
console.info(...);
console.warn(...);

These functions will log different types of items (which can be filtered based on log, info, error or warn) and will not cause errors when console is not available. These functions will work in Firebug and Chrome consoles.

instanceof

The Left Hand Side (LHS) operand is the actual object being tested to the Right Hand Side (RHS) operand which is the actual constructor of a class. The basic definition is:

Checks the current object and returns true if the object
is of the specified object type.

Here are some good examples and here is an example taken directly from Mozilla's developer site:

var color1 = new String("green");
color1 instanceof String; // returns true
var color2 = "coral"; //no type specified
color2 instanceof String; // returns false (color2 is not a String object)

One thing worth mentioning is instanceof evaluates to true if the object inherits from the classe's prototype:

var p = new Person("Jon");
p instanceof Person

That is p instanceof Person is true since p inherits from Person.prototype.

Per the OP's request

I've added a small example with some sample code and an explanation.

When you declare a variable you give it a specific type.

For instance:

int i;
float f;
Customer c;

The above show you some variables, namely i, f, and c. The types are integer, float and a user defined Customer data type. Types such as the above could be for any language, not just JavaScript. However, with JavaScript when you declare a variable you don't explicitly define a type, var x, x could be a number / string / a user defined data type. So what instanceof does is it checks the object to see if it is of the type specified so from above taking the Customer object we could do:

var c = new Customer();
c instanceof Customer; //Returns true as c is just a customer
c instanceof String; //Returns false as c is not a string, it's a customer silly!

Above we've seen that c was declared with the type Customer. We've new'd it and checked whether it is of type Customer or not. Sure is, it returns true. Then still using the Customer object we check if it is a String. Nope, definitely not a String we newed a Customer object not a String object. In this case, it returns false.

It really is that simple!

As others have said, std::max_element() and std::min_element() return iterators, which need to be dereferenced to obtain the value.

The advantage of returning an iterator (rather than just the value) is that it allows you to determine the position of the (first) element in the container with the maximum (or minimum) value.

For example (using C++11 for brevity):

#include <vector>
#include <algorithm>
#include <iostream>

int main()
{
    std::vector<double> v {1.0, 2.0, 3.0, 4.0, 5.0, 1.0, 2.0, 3.0, 4.0, 5.0};

    auto biggest = std::max_element(std::begin(v), std::end(v));
    std::cout << "Max element is " << *biggest
        << " at position " << std::distance(std::begin(v), biggest) << std::endl;

    auto smallest = std::min_element(std::begin(v), std::end(v));
    std::cout << "min element is " << *smallest
        << " at position " << std::distance(std::begin(v), smallest) << std::endl;
}

This yields:

Max element is 5 at position 4
min element is 1 at position 0

Note:

Using std::minmax_element() as suggested in the comments above may be faster for large data sets, but may give slightly different results. The values for my example above would be the same, but the position of the "max" element would be 9 since...

If several elements are equivalent to the largest element, the iterator to the last such element is returned.

Here's my work around for this I hope it helps :

<TouchableOpacity
    onPress={() => {
        this.onSubmit()
    }}
    disabled={this.state.validity}
    style={this.state.validity ?
          SignUpStyleSheet.inputStyle :
          [SignUpStyleSheet.inputAndButton, {opacity: 0.5}]}>
    <Text style={SignUpStyleSheet.buttonsText}>Sign-Up</Text>
</TouchableOpacity>

in SignUpStyleSheet.inputStyle holds the style for the button when it disabled or not, then in style={this.state.validity ? SignUpStyleSheet.inputStyle : [SignUpStyleSheet.inputAndButton, {opacity: 0.5}]} I add the opacity property if the button is disabled.

Just try.

Just create a Pair<TFirst, TSecond> type and use that as your value.

I have an example of one in my C# in Depth source code. Reproduced here for simplicity:

using System;
using System.Collections.Generic;

public sealed class Pair<TFirst, TSecond>
    : IEquatable<Pair<TFirst, TSecond>>
{
    private readonly TFirst first;
    private readonly TSecond second;

    public Pair(TFirst first, TSecond second)
    {
        this.first = first;
        this.second = second;
    }

    public TFirst First
    {
        get { return first; }
    }

    public TSecond Second
    {
        get { return second; }
    }

    public bool Equals(Pair<TFirst, TSecond> other)
    {
        if (other == null)
        {
            return false;
        }
        return EqualityComparer<TFirst>.Default.Equals(this.First, other.First) &&
               EqualityComparer<TSecond>.Default.Equals(this.Second, other.Second);
    }

    public override bool Equals(object o)
    {
        return Equals(o as Pair<TFirst, TSecond>);
    }

    public override int GetHashCode()
    {
        return EqualityComparer<TFirst>.Default.GetHashCode(first) * 37 +
               EqualityComparer<TSecond>.Default.GetHashCode(second);
    }
}

I found after trying lots of convoluted examples that very simple approach worked for me.

I just wanted to take a dump of a db from local and import it on a remote instance:

on the local machine:

mongodump -d databasename

then I scp'd my dump to my server machine:

scp -r dump [email protected]:~

then from the parent dir of the dump simply:

mongorestore 

and that imported the database.

assuming mongodb service is running of course.

Just set the selectIndex of the associated <select> tag to -1 as the last step of your processing event.

mySelect = document.getElementById("idlist");
mySelect.selectedIndex = -1; 

It works every time, removing the highlight and allowing you to select the same (or different) element again .

I still had an issue with it passing the format yyyy-MM-dd, but I got around it by changing the Date.cshtml:

@model DateTime?

@{
    string date = string.Empty;
    if (Model != null)
    {
        date = string.Format("{0}-{1}-{2}", Model.Value.Year, Model.Value.Month, Model.Value.Day);
    }

    @Html.TextBox(string.Empty, date, new { @class = "datefield", type = "date"  })
}

For now i think best emulator is https://app.crossbrowsertesting.com

It has real sizes and virtual keyboard (that is the most important thing) , zooming events...

Also https://appetize.io/demo has same things but it has time limit.

Have you tried copying the schema file to the XML Schema Caching folder for VS? You can find the location of that folder by looking at VS Tools/Options/Test Editor/XML/Miscellaneous. Unfortunately, i don't know where's the schema file for the MS Enterprise Library 4.0.

Update: After installing MS Enterprise Library, it seems there's no .xsd file. However, there's a tool for editing the configuration - EntLibConfig.exe, which you can use to edit the configuration files. Also, if you add the proper config sections to your config file, VS should be able to parse the config file properly. (EntLibConfig will add these for you, or you can add them yourself). Here's an example for the loggingConfiguration section:

<configSections>
    <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</configSections>

You also need to add a reference to the appropriate assembly in your project.

Easy route to avoid messing with PATH variables: re-install git and select "Use Git from the Windows Command Prompt". It'll take of the PATH variables for you as mentioned. see screenshot

You don't need jQuery for this. You can use JavaScript's .childNodes.length.

Just make sure to subtract 1 if you don't want to include the default text node (which is empty by default). Thus, you'd use the following:

var count = elem.childNodes.length - 1;

I think the correct syntax is:

cmd /k "cd c:\<folder name>"

Solved using a solution i found googling by Yogi Anand: https://productforums.google.com/d/msg/docs/3qsR2m-1Xx8/sSU6Z6NYLOcJ

The example below counts the number of non-empty rows in the range A3:C, remember to update both ranges in the formula with your range of interest.

=ArrayFormula(SUM(SIGN(MMULT(LEN(A3:C), TRANSPOSE(SIGN(COLUMN(A3:C)))))))

Also make sure to avoid circular dependencies, it will happen if you for example count the number of non-empty rows in A:C and place this formula in the A or C column.

The OSIV Anti-Pattern

Instead of letting the business layer decide how it’s best to fetch all the associations that are needed by the View layer, OSIV (Open Session in View) forces the Persistence Context to stay open so that the View layer can trigger the Proxy initialization, as illustrated by the following diagram.

• The OpenSessionInViewFilter calls the openSession method of the underlying SessionFactory and obtains a new Session.
• The Session is bound to the TransactionSynchronizationManager.
• The OpenSessionInViewFilter calls the doFilter of the javax.servlet.FilterChain object reference and the request is further processed
• The DispatcherServlet is called, and it routes the HTTP request to the underlying PostController.
• The PostController calls the PostService to get a list of Post entities.
• The PostService opens a new transaction, and the HibernateTransactionManager reuses the same Session that was opened by the OpenSessionInViewFilter.
• The PostDAO fetches the list of Post entities without initializing any lazy association.
• The PostService commits the underlying transaction, but the Session is not closed because it was opened externally.
• The DispatcherServlet starts rendering the UI, which, in turn, navigates the lazy associations and triggers their initialization.
• The OpenSessionInViewFilter can close the Session, and the underlying database connection is released as well.

At first glance, this might not look like a terrible thing to do, but, once you view it from a database perspective, a series of flaws start to become more obvious.

The service layer opens and closes a database transaction, but afterward, there is no explicit transaction going on. For this reason, every additional statement issued from the UI rendering phase is executed in auto-commit mode. Auto-commit puts pressure on the database server because each transaction issues a commit at end, which can trigger a transaction log flush to disk. One optimization would be to mark the Connection as read-only which would allow the database server to avoid writing to the transaction log.

There is no separation of concerns anymore because statements are generated both by the service layer and by the UI rendering process. Writing integration tests that assert the number of statements being generated requires going through all layers (web, service, DAO) while having the application deployed on a web container. Even when using an in-memory database (e.g. HSQLDB) and a lightweight webserver (e.g. Jetty), these integration tests are going to be slower to execute than if layers were separated and the back-end integration tests used the database, while the front-end integration tests were mocking the service layer altogether.

The UI layer is limited to navigating associations which can, in turn, trigger N+1 query problems. Although Hibernate offers @BatchSize for fetching associations in batches, and FetchMode.SUBSELECT to cope with this scenario, the annotations are affecting the default fetch plan, so they get applied to every business use case. For this reason, a data access layer query is much more suitable because it can be tailored to the current use case data fetch requirements.

Last but not least, the database connection is held throughout the UI rendering phase which increases connection lease time and limits the overall transaction throughput due to congestion on the database connection pool. The more the connection is held, the more other concurrent requests are going to wait to get a connection from the pool.

Spring Boot and OSIV

Unfortunately, OSIV (Open Session in View) is enabled by default in Spring Boot, and OSIV is really a bad idea from a performance and scalability perspective.

So, make sure that in the application.properties configuration file, you have the following entry:

spring.jpa.open-in-view=false

This will disable OSIV so that you can handle the LazyInitializationException the right way.

Starting with version 2.0, Spring Boot issues a warning when OSIV is enabled by default, so you can discover this problem long before it affects a production system.

To set ANDROID_HOME, variable, you need to know how you installed android dev setup.

If you don't know you can check if the following paths exist in your machine. Add the following to .bashrc, .zshrc, or .profile depending on what you use

If you installed with homebrew,

export ANDROID_HOME=/usr/local/opt/android-sdk

Check if this path exists:

If you installed android studio following the website,

export ANDROID_HOME=~/Library/Android/sdk

Finally add it to path:

export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

If you're too lazy to open an editor do this:

echo "export ANDROID_HOME=~/Library/Android/sdk" >> ~/.bashrc
echo "export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools" >> ~/.bashrc

<script type = “text/template”> … </script> is obsolete. Use <template> tag instead.

Note that adjusting the width of a column in the thead will affect the whole table

<table>
    <thead>
        <tr width="25">
            <th>Name</th>
            <th>Email</th>
        </tr>
    </thead>
    <tr>
        <td>Joe</td>
        <td>[email protected]</td>
    </tr>
</table>

In my case, the width on the thead > tr was overriding the width on table > tr > td directly.

You should analyze your style.css file, possibly using Developer Tools in your favorite browser, to see which rule sets font size on the element in a manner that overrides the one in a style attribute. Apparently, it has to be one using the !important specifier, which generally indicates poor logic and structure in styling.

Primarily, modify the style.css file so that it does not use !important. Failing this, add !important to the rule in style attribute. But you should aim at reducing the use of !important, not increasing it.

There is no float type. Looks like you want float64. You could also use float32 if you only need a single-precision floating point value.

package main

import "fmt"

func main() {
    i := 5
    f := float64(i)
    fmt.Printf("f is %f\n", f)
}

Request.Form is a NameValueCollection. In NameValueCollection you can find the GetAllValues() method.

By the way the LINQ method also works.

I used a method similar to user496892:

SPBoundField hiddenField = new SPBoundField();
hiddenField.HeaderText = "Header";
hiddenField.DataField = "DataFieldName";
grid.Columns.Add(hiddenField);

grid.DataSource = myDataSource;
grid.DataBind();

hiddenField.Visible = false;

myObject.getClass().getDeclaredConstructors(types list).newInstance(args list);

Edit: according to the comments seems like pointing class and method names is not enough for some users. For more info take a look at the documentation for getting constuctor and invoking it.

Try using another temporary pair:

pair<string,double> temp;
vector<pair<string,double>> revenue;

// Inside the loop
temp.first = "string";
temp.second = map[i].second;
revenue.push_back(temp);

The left hand side of the = operator needs to be a variable. What you're doing here is telling python: "You know the number one? Set it to the inputted string.". 1 is a literal number, not a variable. 1 is always 1, you can't "set" it to something else.

A variable is like a box in which you can store a value. 1 is a value that can be stored in the variable. The input call returns a string, another value that can be stored in a variable.

Instead, use lists:

import random

namelist = []
namelist.append(input("Please enter name 1:"))  #Stored in namelist[0]
namelist.append(input('Please enter name 2:'))  #Stored in namelist[1]
namelist.append(input('Please enter name 3:'))  #Stored in namelist[2]
namelist.append(input('Please enter name 4:'))  #Stored in namelist[3]
namelist.append(input('Please enter name 5:'))  #Stored in namelist[4]

nameindex = random.randint(0, 5)
print('Well done {}. You are the winner!'.format(namelist[nameindex]))

Using a for loop, you can cut down even more:

import random

namecount = 5
namelist=[]
for i in range(0, namecount):
  namelist.append(input("Please enter name %s:" % (i+1))) #Stored in namelist[i]

nameindex = random.randint(0, namecount)
print('Well done {}. You are the winner!'.format(namelist[nameindex]))

Query would be like this:

SELECT ID, AccountID, Quantity, 
       SUM(Quantity) OVER (PARTITION BY AccountID ) AS TopBorcT 

       FROM #Empl ORDER BY AccountID

Partition by works like group by. Here we are grouping by AccountID so sum would be corresponding to AccountID.

First first case, AccountID = 1 , then sum(quantity) = 10 + 5 + 2 => 17 & For AccountID = 2, then sum(Quantity) = 7+3 => 10

so result would appear like attached snapshot.

If you have a look at MySQL Improved Extension Overview, it should tell you everything you need to know about the differences between the two.

The main useful features are:

• an Object-oriented interface
• support for prepared statements
• support for multiple statements
• support for transactions
• enhanced debugging capabilities
• embedded server support.

@Override

        return new AlertDialog.Builder(this)
        .setMessage("text here")
        .setPositiveButton("OK", new DialogInterface.OnClickListener() 
        {                   
            @Override
            public void onClick(DialogInterface arg0, int arg1) 
            {
                try
                {

                }//end try
                catch(Exception e)
                {
                    Toast.makeText(getBaseContext(),  "", Toast.LENGTH_LONG).show();
                }//end catch
            }//end onClick()
        }).create();                
    }//end case
  }//end switch
    return null;
}//end onCreateDialog

I have resolved it , this way

import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Locale;

public class DateParser {

    public static void main(String args[]) throws Exception {

        DateParser dateParser = new DateParser();

        String str = dateParser.getparsedDate("2012-11-17T00:00:00.000-05:00");
        System.out.println(str);
    }


    private String getparsedDate(String date) throws Exception {
        DateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS", Locale.US);
        String s1 = date;
        String s2 = null;
        Date d;
        try {
            d = sdf.parse(s1);
            s2 = (new SimpleDateFormat("MM/yyyy")).format(d);

        } catch (ParseException e) {

            e.printStackTrace();
        }

        return s2;

    }

}

You can:

mkdir -p folder/subfolder

The -p flag causes any parent directories to be created if necessary.

LENGTH() does return the string length (just verified). I suppose that your data is padded with blanks - try

SELECT typ, LENGTH(TRIM(t1.typ))
FROM AUTA_VIEW t1;

instead.

As OraNob mentioned, another cause could be that CHAR is used in which case LENGTH() would also return the column width, not the string length. However, the TRIM() approach also works in this case.
