Let's go over the basics: "Accessor" and "Mutator" are just fancy names fot a getter and a setter. A getter, "Accessor", returns a class's variable or its value. A setter, "Mutator", sets a class variable pointer or its value.

So first you need to set up a class with some variables to get/set:

public class IDCard
{
    private String mName;
    private String mFileName;
    private int mID;

}

But oh no! If you instantiate this class the default values for these variables will be meaningless. B.T.W. "instantiate" is a fancy word for doing:

IDCard test = new IDCard();

So - let's set up a default constructor, this is the method being called when you "instantiate" a class.

public IDCard()
{
    mName = "";
    mFileName = "";
    mID = -1;
}

But what if we do know the values we wanna give our variables? So let's make another constructor, one that takes parameters:

public IDCard(String name, int ID, String filename)
{
    mName = name;
    mID = ID;
    mFileName = filename;
}

Wow - this is nice. But stupid. Because we have no way of accessing (=reading) the values of our variables. So let's add a getter, and while we're at it, add a setter as well:

public String getName()
{
    return mName;
}

public void setName( String name )
{
    mName = name;
}

Nice. Now we can access mName. Add the rest of the accessors and mutators and you're now a certified Java newbie. Good luck.

if ($variable % 6 == 0) {
    echo 'This number is divisible by 6.';
}:

Make divisible by 6:

$variable += (6 - ($variable % 6)) % 6; // faster than while for large divisors

You don't need CSS for this.

     <img src="abc"/>

now with link:

     <a href="#myLink"><img src="abc"/></a>

Or with jquery, later on, you can use the wrap property, see these questions answer:

how to add a link to an image using jquery?

GPS does not need any kind of internet or wireless connection, but there are technologies like A-GPS that use the mobile network to shorten the time to first fix, or the initial positioning or increase the precision in situations when there is a low satellite visibility.

Android phones tend to use A-GPS. If there is no connectivity, they use pure GPS. They do not override the data network mode. If you deactivated it, the phone won't use any data connection (which is handy if you are abroad, and do not want to pay expensive data roaming).

The most effective debugging tool is still careful thought, coupled with judiciously placed print statements.

Brian Kernighan, "Unix for Beginners" (1979)

(And enhancing print statements with Data::Dumper)

Not possible, per MSDN:

You can have the same code execute for multiple trigger types, but the syntax does not allow for multiple code blocks in one trigger:

Trigger on an INSERT, UPDATE, or DELETE statement to a table or view (DML Trigger)

CREATE TRIGGER [ schema_name . ]trigger_name 
ON { table | view } 
[ WITH <dml_trigger_option> [ ,...n ] ]
{ FOR | AFTER | INSTEAD OF } 
{ [ INSERT ] [ , ] [ UPDATE ] [ , ] [ DELETE ] } 
[ NOT FOR REPLICATION ] 
AS { sql_statement  [ ; ] [ ,...n ] | EXTERNAL NAME <method specifier [ ; ] > }

This will only remove the tab, newlines, spaces and nothing else.

import re
myString = "I want to Remove all white \t spaces, new lines \n and tabs \t"
output   = re.sub(r"[\n\t\s]*", "", myString)

OUTPUT:

IwantoRemoveallwhiespaces,newlinesandtabs

Good day!

You can use the LocalForward directive in your host yam section of ~/.ssh/config:

LocalForward 5901 computer.myHost.edu:5901

The computer "name" is resolved from the IP address by the underlying DNS (Domain Name System) library of the OS. There's no universal concept of a computer name across OSes, but DNS is generally available. If the computer name hasn't been configured so DNS can resolve it, it isn't available.

import java.net.InetAddress;
import java.net.UnknownHostException;

String hostname = "Unknown";

try
{
    InetAddress addr;
    addr = InetAddress.getLocalHost();
    hostname = addr.getHostName();
}
catch (UnknownHostException ex)
{
    System.out.println("Hostname can not be resolved");
}

You can read file data line by line as below:

String fileLoc = "fileLocationInTheDisk";

List<String> lines = Files.lines(Path.of(fileLoc), StandardCharsets.UTF_8).collect(Collectors.toList());

There are a few ways to do this it seems.

Option 1: Native Angular

Angular provides an $anchorScroll service, but the documentation is severely lacking and I've not been able to get it to work.

Check out http://www.benlesh.com/2013/02/angular-js-scrolling-to-element-by-id.html for some insight into $anchorScroll.

Option 2: Custom Directive / Native JavaScript

Another way I tested out was creating a custom directive and using el.scrollIntoView(). This works pretty decently by basically doing the following in your directive link function:

var el = document.getElementById(attrs.href);
el.scrollIntoView();

However, it seems a bit overblown to do both of these when the browser natively supports this, right?

Option 3: Angular Override / Native Browser

If you take a look at http://docs.angularjs.org/guide/dev_guide.services.$location and its HTML Link Rewriting section, you'll see that links are not rewritten in the following:

Links that contain target element

Example: <a href="/ext/link?a=b" target="_self">link</a>

So, all you have to do is add the target attribute to your links, like so:

<a href="#anchorLinkID" target="_self">Go to inpage section</a>

Angular defaults to the browser and since its an anchor link and not a different base url, the browser scrolls to the correct location, as desired.

I went with option 3 because its best to rely on native browser functionality here, and saves us time and effort.

Gotta note that after a successful scroll and hash change, Angular does follow up and rewrite the hash to its custom style. However, the browser has already completed its business and you are good to go.

First off, custom events don't play well with React components natively. So you cant just say <div onMyCustomEvent={something}> in the render function, and have to think around the problem.

Secondly, after taking a peek at the documentation for the library you're using, the event is actually fired on document.body, so even if it did work, your event handler would never trigger.

Instead, inside componentDidMount somewhere in your application, you can listen to nv-enter by adding

document.body.addEventListener('nv-enter', function (event) {
    // logic
});

Then, inside the callback function, hit a function that changes the state of the component, or whatever you want to do.

Here is the one liner i use, from terminal, to test the content of yml file(s):

$ ruby  -r yaml -r pp  -e 'pp YAML.load_file("/Users/za/project/application.yml")'
{"logging"=>
  {"path"=>"/var/logs/",
   "file"=>"TacoCloud.log",
   "level"=>
    {"root"=>"WARN", "org"=>{"springframework"=>{"security"=>"DEBUG"}}}}}

You just need to add three file and two css links. You can either cdn's as well. Links for the js files and css files are as such :-

1. jQuery.dataTables.min.js
2. dataTables.bootstrap.min.js
3. dataTables.bootstrap.min.css
4. bootstrap-datepicker.css
5. bootstrap-datepicker.js

They are valid if you are using bootstrap in your project.

I hope this will help you. Regards, Vivek Singla

Slightly building upon the answers of other people. Now allowing you to specify the file you want to read from and the variable you want the result put into:

@echo off
for /f "delims=" %%x in (%2) do (
set %1=%%x
exit /b
)

This means you can use the above like this (assuming you called it getline.bat)

c:\> dir > test-file
c:\> getline variable test-file
c:\> set variable  
variable= Volume in drive C has no label.

Yeah, the best way is to convert the object notation to a flat key-value string representation, as mentioned in this comment: https://stackoverflow.com/a/39357531/2529199

I wanted to highlight an alternative method using this NPM library: https://www.npmjs.com/package/dot-object which lets you manipulate different objects using dot notation.

I used this pattern to programatically create a nested object property when accepting the key-value as a function variable, as follows:

const dot = require('dot-object');

function(docid, varname, varvalue){
  let doc = dot.dot({
      [varname]: varvalue 
  });

  Mongo.update({_id:docid},{$set:doc});
}

This pattern lets me use nested as well as single-level properties interchangeably, and insert them cleanly into Mongo.

If you need to play around with JS Objects beyond just Mongo, especially on the client-side but have consistency when working with Mongo, this library gives you more options than the earlier mentioned mongo-dot-notation NPM module.

P.S I originally wanted to just mention this as a comment but apparently my S/O rep isn't high enough to post a comment. So, not trying to muscle in on SzybkiSasza's comment, just wanted to highlight providing an alternative module.

There are no sleep() functions in the pre-C11 C Standard Library, but POSIX does provide a few options.

The POSIX function sleep() (unistd.h) takes an unsigned int argument for the number of seconds desired to sleep. Although this is not a Standard Library function, it is widely available, and glibc appears to support it even when compiling with stricter settings like --std=c11.

The POSIX function nanosleep() (time.h) takes two pointers to timespec structures as arguments, and provides finer control over the sleep duration. The first argument specifies the delay duration. If the second argument is not a null pointer, it holds the time remaining if the call is interrupted by a signal handler.

Programs that use the nanosleep() function may need to include a feature test macro in order to compile. The following code sample will not compile on my linux system without a feature test macro when I use a typical compiler invocation of gcc -std=c11 -Wall -Wextra -Wpedantic.

POSIX once had a usleep() function (unistd.h) that took a useconds_t argument to specify sleep duration in microseconds. This function also required a feature test macro when used with strict compiler settings. Alas, usleep() was made obsolete with POSIX.1-2001 and should no longer be used. It is recommended that nanosleep() be used now instead of usleep().

#define _POSIX_C_SOURCE  199309L     // feature test macro for nanosleep()

#include <stdio.h>
#include <unistd.h>    // for sleep()
#include <time.h>      // for nanosleep()

int main(void)
{
    // use unsigned sleep(unsigned seconds)
    puts("Wait 5 sec...");
    sleep(5);

    // use int nanosleep(const struct timespec *req, struct timespec *rem);
    puts("Wait 2.5 sec...");
    struct timespec ts = { .tv_sec = 2,          // seconds to wait
                           .tv_nsec = 5e8 };     // additional nanoseconds
    nanosleep(&ts, NULL);
    puts("Bye");

    return 0;
}

Addendum:

C11 does have the header threads.h providing thrd_sleep(), which works identically to nanosleep(). GCC did not support threads.h until 2018, with the release of glibc 2.28. It has been difficult in general to find implementations with support for threads.h (Clang did not support it for a long time, but I'm not sure about the current state of affairs there). You will have to use this option with care.

Optionally, add -Encoding utf8 to Out-File as the default encoding is not really ideal for many uses.

Kotlin for XML

app:cardBackgroundColor="@android:color/red"

code

cardName.setCardBackgroundColor(ContextCompat.getColor(this, R.color.colorGray));

I would suggest this to hide elements (as others have suggested):

document.getElementById(id).style.display = 'none';

But to make elements visible, I'd suggest this (instead of display = 'block'):

document.getElementById(id).style.display = '';

The reason is that using display = 'block' is causing additional margin/whitespace next to the element being made visible in both IE (11) and Chrome (Version 43.0.2357.130 m) on the page I'm working on.

When you first load a page in Chrome, an element without a style attribute will appear like this in the DOM inspector:

element.style {
}

Hiding it using the standard JavaScript makes it this, as expected:

element.style {
  display: none;
}

Making it visible again using display = 'block' changes it to this:

element.style {
  display: block;
}

Which is not the same as it originally was. This could very well not make any difference in the majority of cases. But in some cases, it does introduce abnormalities.

Using display = '' does restore it to its original state in the DOM inspector, so it seems like the better approach.

Better yet - just HTML:

<a [routerLink]="[]" [queryParams]="{key: 'value'}">Your Query Params Link</a>

Note the empty array instead of just doing routerLink="" or [routerLink]="''"

Extended Kon's code to help debug a stored procedure:

    private void ExtractSqlCommandForDebugging(SqlCommand cmd)
    {
        string sql = "exec " + cmd.CommandText;
        bool first = true;
        foreach (SqlParameter p in cmd.Parameters)
        {
            string value = ((p.Value == DBNull.Value) ? "null"
                            : (p.Value is string) ? "'" + p.Value + "'"
                            : p.Value.ToString());
            if (first)
            {
                sql += string.Format(" {0}={1}", p.ParameterName, value);
                first = false;
            }
            else
            {
                sql += string.Format("\n , {0}={1}", p.ParameterName, value);
            }
        }
        sql += "\nGO";
        Debug.WriteLine(sql);
    }

In my first test case, it generated:

You will probably need to add some more conditional "..is..." type assignments, e.g. for dates and times.

According to http://youmightnotneedjquery.com/#ready a nice replacement that still works with IE8 is

function ready(fn) {_x000D_
  if (document.readyState != 'loading') {_x000D_
    fn();_x000D_
  } else if (document.addEventListener) {_x000D_
    document.addEventListener('DOMContentLoaded', fn);_x000D_
  } else {_x000D_
    document.attachEvent('onreadystatechange', function() {_x000D_
      if (document.readyState != 'loading')_x000D_
        fn();_x000D_
    });_x000D_
  }_x000D_
}_x000D_
_x000D_
// test_x000D_
window.ready(function() {_x000D_
    alert('it works');_x000D_
});

improvements: Personally I would also check if the type of fn is a function. And as @elliottregan suggested remove the event listener after use.

The reason I answer this question late is because I was searching for this answer but could not find it here. And I think this is the best solution.

You can use this

"abcdefg".index('c')   #=> 2

Don't serialize FormData with POSTing to server. Do this:

this.uploadFileToUrl = function(file, title, text, uploadUrl){
    var payload = new FormData();

    payload.append("title", title);
    payload.append('text', text);
    payload.append('file', file);

    return $http({
        url: uploadUrl,
        method: 'POST',
        data: payload,
        //assign content-type as undefined, the browser
        //will assign the correct boundary for us
        headers: { 'Content-Type': undefined},
        //prevents serializing payload.  don't do it.
        transformRequest: angular.identity
    });
}

Then use it:

MyService.uploadFileToUrl(file, title, text, uploadUrl).then(successCallback).catch(errorCallback);

This should work for you to get the contents of list.txt file

$headers = array('http'=>array('method'=>'GET','header'=>'Content: type=application/json \r\n'.'$agent \r\n'.'$hash'));

$context=stream_context_create($headers);

$str = file_get_contents("list.txt",FILE_USE_INCLUDE_PATH,$context);

$str=utf8_encode($str);

$str=json_decode($str,true);

print_r($str);

You may need the following two functions: pad- to pad(when doing encryption) and unpad- to unpad (when doing decryption) when the length of input is not a multiple of BLOCK_SIZE.

BS = 16
pad = lambda s: s + (BS - len(s) % BS) * chr(BS - len(s) % BS) 
unpad = lambda s : s[:-ord(s[len(s)-1:])]

So you're asking the length of key? You can use the md5sum of the key rather than use it directly.

More, according to my little experience of using PyCrypto, the IV is used to mix up the output of a encryption when input is same, so the IV is chosen as a random string, and use it as part of the encryption output, and then use it to decrypt the message.

And here's my implementation, hope it will be useful for you:

import base64
from Crypto.Cipher import AES
from Crypto import Random

class AESCipher:
    def __init__( self, key ):
        self.key = key

    def encrypt( self, raw ):
        raw = pad(raw)
        iv = Random.new().read( AES.block_size )
        cipher = AES.new( self.key, AES.MODE_CBC, iv )
        return base64.b64encode( iv + cipher.encrypt( raw ) ) 

    def decrypt( self, enc ):
        enc = base64.b64decode(enc)
        iv = enc[:16]
        cipher = AES.new(self.key, AES.MODE_CBC, iv )
        return unpad(cipher.decrypt( enc[16:] ))

If you want to have a new data frame then:

import pandas as pd
old = pd.DataFrame({'A' : [4,5], 'B' : [10,20], 'C' : [100,50], 'D' : [-30,-50]})
new=  old[['A', 'C', 'D']]

Use double braces {{ or }} so your code becomes:

sb.AppendLine(String.Format("public {0} {1} {{ get; private set; }}", 
prop.Type, prop.Name));

// For prop.Type of "Foo" and prop.Name of "Bar", the result would be:
// public Foo Bar { get; private set; }

As pointed out in some comments, you need to edit the policies of ImageMagick in /etc/ImageMagick-7/policy.xml. More particularly, in ArchLinux at the time of writing (05/01/2019) the following line is uncommented:

<policy domain="coder" rights="none" pattern="{PS,PS2,PS3,EPS,PDF,XPS}" />

Just wrap it between <!-- and --> to comment it, and pdf conversion should work again.

Note that on Python 3, it's not really fair to say any of:

• strs are UTFx for any x (eg. UTF8)

• strs are Unicode

• strs are ordered collections of Unicode characters

Python's str type is (normally) a sequence of Unicode code points, some of which map to characters.

Even on Python 3, it's not as simple to answer this question as you might imagine.

An obvious way to test for ASCII-compatible strings is by an attempted encode:

"Hello there!".encode("ascii")
#>>> b'Hello there!'

"Hello there... ?!".encode("ascii")
#>>> Traceback (most recent call last):
#>>>   File "", line 4, in <module>
#>>> UnicodeEncodeError: 'ascii' codec can't encode character '\u2603' in position 15: ordinal not in range(128)

The error distinguishes the cases.

In Python 3, there are even some strings that contain invalid Unicode code points:

"Hello there!".encode("utf8")
#>>> b'Hello there!'

"\udcc3".encode("utf8")
#>>> Traceback (most recent call last):
#>>>   File "", line 19, in <module>
#>>> UnicodeEncodeError: 'utf-8' codec can't encode character '\udcc3' in position 0: surrogates not allowed

The same method to distinguish them is used.

The easy way is by using sprintf. I know others have suggested itoa, but a) it isn't part of the standard library, and b) sprintf gives you formatting options that itoa doesn't.

You need to use df.shift here.
df.shift(i) shifts the entire dataframe by i units down.

So, for i = 1:

Input:

    x1   x2  
0  206  214  
1  226  234  
2  245  253  
3  265  272    
4  283  291

Output:

    x1   x2
0  Nan  Nan   
1  206  214  
2  226  234  
3  245  253  
4  265  272 

So, run this script to get the expected output:

import pandas as pd

df = pd.DataFrame({'x1': ['206', '226', '245',' 265', '283'],
                   'x2': ['214', '234', '253', '272', '291']})

print(df)
df['x2'] = df['x2'].shift(1)
print(df)

Use .col instead of col-lg-3 :

<div class="row">
   <div class="col">
      Fixed content
   </div>
   <div class="col-lg-9">
      Normal scrollable content
   </div>
</div>

Use a simple background image for the textarea suffice.

Or

<div onselectstart="return false">your text</div>

As PPK points out here, in IE you can also use

e.cancelBubble = true;

With Groovy, you can leverage Ant to do:

new AntBuilder().copy( todir:'/path/to/destination/folder' ) {
  fileset( dir:'/path/to/src/folder' )
}

AntBuilder is part of the distribution and the automatic imports list which means it is directly available for any groovy code.

see this example you get full year month day information from here

function getAge(dateString) {
    var today = new Date();
    var birthDate = new Date(dateString);
    var age = today.getFullYear() - birthDate.getFullYear();
    var m = today.getMonth() - birthDate.getMonth();
    var da = today.getDate() - birthDate.getDate();
    if (m < 0 || (m === 0 && today.getDate() < birthDate.getDate())) {
        age--;
    }
    if(m<0){
        m +=12;
    }
    if(da<0){
        da +=30;
    }
    return age+" years "+ Math.abs(m) + "months"+ Math.abs(da) + " days";
}
alert('age: ' + getAge("1987/08/31"));

Another option is to use "localStorage". You can easealy request the value with javascript in another page.

On the first page, you use the following snippet of javascript code to set the localStorage:

<script>    
   localStorage.setItem("serialNumber", "abc123def456");
</script>

On the second page, you can retrieve the value with the following javascript code snippet:

<script>    
   console.log(localStorage.getItem("serialNumber"));
</script>

On Google Chrome You can vizualize the values pressing F12 > Application > Local Storage.

Thus far, nobody seems to have addressed the memory footprint of each of these lists besides the general consensus that a LinkedList is "lots more" than an ArrayList so I did some number crunching to demonstrate exactly how much both lists take up for N null references.

Since references are either 32 or 64 bits (even when null) on their relative systems, I have included 4 sets of data for 32 and 64 bit LinkedLists and ArrayLists.

Note: The sizes shown for the ArrayList lines are for trimmed lists - In practice, the capacity of the backing array in an ArrayList is generally larger than its current element count.

Note 2: (thanks BeeOnRope) As CompressedOops is default now from mid JDK6 and up, the values below for 64-bit machines will basically match their 32-bit counterparts, unless of course you specifically turn it off.

The result clearly shows that LinkedList is a whole lot more than ArrayList, especially with a very high element count. If memory is a factor, steer clear of LinkedLists.

The formulas I used follow, let me know if I have done anything wrong and I will fix it up. 'b' is either 4 or 8 for 32 or 64 bit systems, and 'n' is the number of elements. Note the reason for the mods is because all objects in java will take up a multiple of 8 bytes space regardless of whether it is all used or not.

ArrayList:

ArrayList object header + size integer + modCount integer + array reference + (array oject header + b * n) + MOD(array oject, 8) + MOD(ArrayList object, 8) == 8 + 4 + 4 + b + (12 + b * n) + MOD(12 + b * n, 8) + MOD(8 + 4 + 4 + b + (12 + b * n) + MOD(12 + b * n, 8), 8)

LinkedList:

LinkedList object header + size integer + modCount integer + reference to header + reference to footer + (node object overhead + reference to previous element + reference to next element + reference to element) * n) + MOD(node object, 8) * n + MOD(LinkedList object, 8) == 8 + 4 + 4 + 2 * b + (8 + 3 * b) * n + MOD(8 + 3 * b, 8) * n + MOD(8 + 4 + 4 + 2 * b + (8 + 3 * b) * n + MOD(8 + 3 * b, 8) * n, 8)

"16:23:01" doesn't match the pattern of "hh:mm:ss tt" - it doesn't have an am/pm designator, and 16 clearly isn't in a 12-hour clock. You're specifying that format in the parsing part, so you need to match the format of the existing data. You want:

DateTime dateTime = DateTime.ParseExact(time, "HH:mm:ss",
                                        CultureInfo.InvariantCulture);

(Note the invariant culture, not the current culture - assuming your input genuinely always uses colons.)

If you want to format it to hh:mm:ss tt, then you need to put that part in the ToString call:

lblClock.Text = date.ToString("hh:mm:ss tt", CultureInfo.CurrentCulture);

Or better yet (IMO) use "whatever the long time pattern is for the culture":

lblClock.Text = date.ToString("T", CultureInfo.CurrentCulture);

Also note that hh is unusual; typically you don't want to 0-left-pad the number for numbers less than 10.

(Also consider using my Noda Time API, which has a LocalTime type - a more appropriate match for just a "time of day".)

Abuse the SecurityManager

System.getSecurityManager().getClassContext()[0].getName();

Or, if not set, use an inner class that extends it (example below shamefully copied from Real's HowTo):

public static class CurrentClassGetter extends SecurityManager {
    public String getClassName() {
        return getClassContext()[1].getName(); 
    }
}

i founded here, its ok with me for linkedin: https://auth0.com/docs/flows/guides/auth-code/call-api-auth-code so my code with with linkedin login here:

ref = 'https://api.linkedin.com/v2/me'
headers = {"content-type": "application/json; charset=UTF-8",'Authorization':'Bearer {}'.format(access_token)}
Linkedin_user_info = requests.get(ref1, headers=headers).json()

I had to set

C:\ProgramData\MySQL\MySQL Server 8.0/my.ini  secure-file-priv=""

When I commented line with secure-file-priv, secure-file-priv was null and I couldn't download data.

^[0-9][0-9]?[^A-Za-z0-9]?po$

You can test it here: http://www.regextester.com/

To use this in C#,

Regex r = new Regex(@"^[0-9][0-9]?[^A-Za-z0-9]?po$");
if (r.Match(someText).Success) {
   //Do Something
}

Remember, @ is a useful symbol that means the parser takes the string literally (eg, you don't need to write \\ for one backslash)

<?php

   $email = "someone@exa mple.com";

   if(!filter_var($email, FILTER_VALIDATE_EMAIL))
      echo "E-mail is not valid";
   else
      echo "E-mail is valid";

128M == 134217728, the number you are seeing.

The memory limit is working fine. When it says it tried to allocate 32 bytes, that the amount requested by the last operation before failing.

Are you building any huge arrays or reading large text files? If so, remember to free any memory you don't need anymore, or break the task down into smaller steps.

If you want to know the number of tables that belong to a certain schema/user, you can also use SQL similar to this one:

SELECT Count(*) FROM DBA_TABLES where OWNER like 'PART_OF_NAME%';

In theory, yes, it's just a matter of plugging things in. Zipfile can give you a file-like object for a file in a zip archive, and image.load will accept a file-like object. So something like this should work:

import zipfile
archive = zipfile.ZipFile('images.zip', 'r')
imgfile = archive.open('img_01.png')
try:
    image = pygame.image.load(imgfile, 'img_01.png')
finally:
    imgfile.close()

In up-to-date implementations of ES, you can use Object.entries:

for (const [key, value] of Object.entries(obj)) { }

or

Object.entries(obj).forEach(([key, value]) => ...)

If you just want to iterate over the values, then use Object.values:

for (const value of Object.values(obj)) { }

or

Object.values(obj).forEach(value => ...)

In addition to the above great answers using Threads, in case you have to use your main thread or prefer an async approach - I wrapped a short class around aio_timers Timer class (to enable repeating)

import asyncio
from aio_timers import Timer

class RepeatingAsyncTimer():
    def __init__(self, interval, cb, *args, **kwargs):
        self.interval = interval
        self.cb = cb
        self.args = args
        self.kwargs = kwargs
        self.aio_timer = None
        self.start_timer()
    
    def start_timer(self):
        self.aio_timer = Timer(delay=self.interval, 
                               callback=self.cb_wrapper, 
                               callback_args=self.args, 
                               callback_kwargs=self.kwargs
                              )
    
    def cb_wrapper(self, *args, **kwargs):
        self.cb(*args, **kwargs)
        self.start_timer()


from time import time
def cb(timer_name):
    print(timer_name, time())

print(f'clock starts at: {time()}')
timer_1 = RepeatingAsyncTimer(interval=5, cb=cb, timer_name='timer_1')
timer_2 = RepeatingAsyncTimer(interval=10, cb=cb, timer_name='timer_2')

The error can be caused by mixing together debug builds and release builds in same executable or dll.

1. in the vs configuration manager, are some of your projects in debug mode and some in release mode?
2. is one of your release projects has the preprocessor symbol DEBUG or _DEBUG defined?
3. is one of your debug projects has the preprocessor symbol NDEBUG defined?

In addition to Biff MaGriff's answer. To export the file using JQuery, redirect the user to a new page.

Never do a git -f to do push as it can result in later disastrous consequences.

You just need to do a git pull of your local branch.

Ex:

git pull origin 'your_local_branch'

and then do a git push

Perhaps setting both of the buttons layout_width properties to "fill_parent" will do the trick.

I just tested this code and it works in the emulator:

<LinearLayout android:layout_width="fill_parent"
          android:layout_height="wrap_content">

    <Button android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="hello world"/>

    <Button android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="goodbye world"/>

</LinearLayout>

Be sure to set layout_width to "fill_parent" on both buttons.

It's compiler dependent. That said, in general using " prioritizes headers in the current working directory over system headers. <> usually is used for system headers. From to the specification (Section 6.10.2):

A preprocessing directive of the form

  # include <h-char-sequence> new-line

searches a sequence of implementation-defined places for a header identified uniquely by the specified sequence between the < and > delimiters, and causes the replacement of that directive by the entire contents of the header. How the places are specified or the header identified is implementation-defined.

A preprocessing directive of the form

  # include "q-char-sequence" new-line

causes the replacement of that directive by the entire contents of the source file identified by the specified sequence between the " delimiters. The named source file is searched for in an implementation-defined manner. If this search is not supported, or if the search fails, the directive is reprocessed as if it read

  # include <h-char-sequence> new-line

with the identical contained sequence (including > characters, if any) from the original directive.

So on most compilers, using the "" first checks your local directory, and if it doesn't find a match then moves on to check the system paths. Using <> starts the search with system headers.

If you're working with an asp.net application and you want to locate assemblies when using the debugger, they are usually put into some temp directory. I wrote the this method to help with that scenario.

private string[] GetAssembly(string[] assemblyNames)
{
    string [] locations = new string[assemblyNames.Length];


    for (int loop = 0; loop <= assemblyNames.Length - 1; loop++)       
    {
         locations[loop] = AppDomain.CurrentDomain.GetAssemblies().Where(a => !a.IsDynamic && a.ManifestModule.Name == assemblyNames[loop]).Select(a => a.Location).FirstOrDefault();
    }
    return locations;
}

If you can't change the source code, or redeploy, but you can examine the running processes on the computer use Process Explorer. I written a detailed description here.

It will list all executing dlls on the system, you may need to determine the process id of your running application, but that is usually not too difficult.

I've written a full description of how do this for a dll inside IIS - http://nodogmablog.bryanhogan.net/2016/09/locating-and-checking-an-executing-dll-on-a-running-web-server/

Here is how I show hover text using JavaScript tooltip:

<script language="JavaScript" type="text/javascript" src="javascript/wz_tooltip.js"></script>

<div class="curhand" onmouseover="this.T_WIDTH=125; return escape('Welcome')">Are you New Here?</div>

Now that the question is clearer, you can just do this in one grep

grep -R --include "*bills*" "put" .

With relevant flags

   -R, -r, --recursive
          Read  all  files  under  each  directory,  recursively;  this is
          equivalent to the -d recurse option.
   --include=GLOB
          Search only files whose base name matches GLOB  (using  wildcard
          matching as described under --exclude).

For people (like me) who really want PathLocationStrategy (i.e. html5Mode) instead of HashLocationStrategy, see How to: Configure your server to work with html5Mode from a third-party wiki:

When you have html5Mode enabled, the # character will no longer be used in your URLs. The # symbol is useful because it requires no server side configuration. Without #, the URL looks much nicer, but it also requires server side rewrites.

Here I only copy three examples from the wiki, in case the Wiki get lost. Other examples can be found by searching keyword "URL rewrite" (e.g. this answer for Firebase).

Yes, you can input multiple items from cin, using exactly the syntax you describe. The result is essentially identical to:

cin >> a;
cin >> b;
cin >> c;

This is due to a technique called "operator chaining".

Each call to operator>>(istream&, T) (where T is some arbitrary type) returns a reference to its first argument. So cin >> a returns cin, which can be used as (cin>>a)>>b and so forth.

Note that each call to operator>>(istream&, T) first consumes all whitespace characters, then as many characters as is required to satisfy the input operation, up to (but not including) the first next whitespace character, invalid character, or EOF.

Add an identity column (PeopleID) and then use a correlated subquery to return the first value for each value.

SELECT *
FROM People p
WHERE PeopleID = (
    SELECT MIN(PeopleID) 
    FROM People 
    WHERE IDNo = p.IDNo
)

There is no way to do this in single query. You have to search the document in first query:

If document exists:

db.bar.update( {user_id : 123456 , "items.item_name" : "my_item_two" } , 
                {$inc : {"items.$.price" : 1} } , 
                false , 
                true);

Else

db.bar.update( {user_id : 123456 } , 
                {$addToSet : {"items" : {'item_name' : "my_item_two" , 'price' : 1 }} } ,
                false , 
                true);

No need to add condition {$ne : "my_item_two" }.

Also in multithreaded enviourment you have to be careful that only one thread can execute the second (insert case, if document did not found) at a time, otherwise duplicate embed documents will be inserted.

Just use CLng(Date).

Note that you need to use Long not Integer for this as the value for the current date is > 32767

Use replace method of string like the following way:

String x="\"abcd";
String z=x.replace("\"", "");
System.out.println(z);

Output:

abcd

Use

var arrayNames = (from DataColumn x in dt.Columns
                  select x.ColumnName).ToArray();

I provide this post for both IntelliJ and Eclipse.

Eclipse:

For making unit test for your project, please follow these steps (I am using Eclipse in order to write this test):

1- Click on New -> Java Project.

2- Write down your project name and click on finish.

3- Right click on your project. Then, click on New -> Class.

4- Write down your class name and click on finish.

Then, complete the class like this:

public class Math {
    int a, b;
    Math(int a, int b) {
        this.a = a;
        this.b = b;
    }
    public int add() {
        return a + b;
    }
}

5- Click on File -> New -> JUnit Test Case.

6- Check setUp() and click on finish. SetUp() will be the place that you initialize your test.

7- Click on OK.

8- Here, I simply add 7 and 10. So, I expect the answer to be 17. Complete your test class like this:

import org.junit.Assert;
import org.junit.Before;
import org.junit.Test;
public class MathTest {
    Math math;
    @Before
    public void setUp() throws Exception {
        math = new Math(7, 10);
    }
    @Test
    public void testAdd() {
        Assert.assertEquals(17, math.add());
    }
}

9- Write click on your test class in package explorer and click on Run as -> JUnit Test.

10- This is the result of the test.

IntelliJ: Note that I used IntelliJ IDEA community 2020.1 for the screenshots. Also, you need to set up your jre before these steps. I am using JDK 11.0.4.

1- Right-click on the main folder of your project-> new -> directory. You should call this 'test'. 2- Right-click on the test folder and create the proper package. I suggest creating the same packaging names as the original class. Then, you right-click on the test directory -> mark directory as -> test sources root. 3- In the right package in the test directory, you need to create a Java class (I suggest to use Test.java). 4- In the created class, type '@Test'. Then, among the options that IntelliJ gives you, select Add 'JUnitx' to classpath. 5- Write your test method in your test class. The method signature is like:

@Test
public void test<name of original method>(){
...
}

You can do your assertions like below:

Assertions.assertTrue(f.flipEquiv(node1_1, node2_1));

These are the imports that I added:

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;

This is the test that I wrote:

You can check your methods like below:

Assertions.assertEquals(<Expected>,<actual>);
Assertions.assertTrue(<actual>);
...

For running your unit tests, right-click on the test and click on Run .

If your test passes, the result will be like below:

I hope it helps. You can see the structure of the project in GitHub https://github.com/m-vahidalizadeh/problem_solving_project.

</httpErrors>

Another option is to use the Decimal.Round Method

I needed to solve similar problem for local repository placed in the main project of multi-module project. Essentially the real path was ${basedir}/lib. Finally I settled on this in my parent.pom:

<repository>
    <id>local-maven-repo</id>
    <url>file:///${basedir}/${project.parent.relativePath}/lib</url>
</repository>

That basedir always shows to current local module, there is no way to get path to "master" project (Maven's shame). Some of my submodules are one dir deeper, some are two dirs deeper, but all of them are direct submodules of the parent that defines the repo URL.

So this does not resolve the problem in general. You may always combine it with Clay's accepted answer and define some other property - works fine and needs to be redefined only for cases where the value from parent.pom is not good enough. Or you may just reconfigure the plugin - which you do only in POM artifacts (parents of other sub-modules). Value extracted into property is probably better if you need it on more places, especially when nothing in the plugin configuration changes.

Using basedir in the value was the essential part here, because URL file://${project.parent.relativePath}/lib did not want to do the trick (I removed one slash to make it relative). Using property that gives me good absolute path and then going relative from it was necessary.

When the path is not URL/URI, it probably is not such a problem to drop basedir.

Here is an example that sorts by the header. This table is dynamic and changes with the JSON size.

I was able to build a dynamic table off of some other people's examples and documentation. http://jsfiddle.net/lastlink/v7pszemn/1/

<tr>
    <th class="{{header}}" ng-repeat="(header, value) in items[0]" ng-click="changeSorting(header)">
    {{header}}
  <i ng-class="selectedCls2(header)"></i>
</tr>

<tbody>
    <tr ng-repeat="row in pagedItems[currentPage] | orderBy:sort.sortingOrder:sort.reverse">
        <td ng-repeat="cell in row">
              {{cell}}
       </td>
    </tr>

Although the columns are out of order, on my .NET project they are in order.

The Javascript interpreter natively stores objects in a hash table. If you're worried about contamination from the prototype chain, you can always do something like this:

// Simple ECMA5 hash table
Hash = function(oSource){
  for(sKey in oSource) if(Object.prototype.hasOwnProperty.call(oSource, sKey)) this[sKey] = oSource[sKey];
};
Hash.prototype = Object.create(null);

var oHash = new Hash({foo: 'bar'});
oHash.foo === 'bar'; // true
oHash['foo'] === 'bar'; // true
oHash['meow'] = 'another prop'; // true
oHash.hasOwnProperty === undefined; // true
Object.keys(oHash); // ['foo', 'meow']
oHash instanceof Hash; // true

You could simply use CSS animated text generator. There are pre-created templates already

   b. Mobile - Button/Touch screen, power button, volume button, sim port.
   c. Car - Steering, Break, Clutch, Accelerator, Key Hole.
   d. Human - Voice, Body, Eye Sight, Hearing, Emotions.

Encapsulation:

1. Process of hiding the details of an object you don't need
2. In other words, hide the properties and operations you don't need from the object but are required for the object to work properly Example:
   a. TV - Internal and connections of Speaker, Display, Power distribution b/w components, Channel mechanism.
   b. Mobile - How the input is parsed and processed, How pressing a button on/off or changes volumes, how sim will connect to service providers.
   c. Car - How turning steering turns the car, How break slow or stops the car, How clutch works, How accelerator increases speed, How key hole switch on/of the car.
   d. Human - How voice is produced, What's inside the body, How eye sight works, How hearing works, How emotions generate and effect us.

ABSTRACT everything you need and ENCAPSULATE everything you don't need ;)

Here is what I would use:

std::cout << std::setprecision (std::numeric_limits<double>::digits10 + 1)
          << 3.14159265358979
          << std::endl;

Basically the limits package has traits for all the build in types.
One of the traits for floating point numbers (float/double/long double) is the digits10 attribute. This defines the accuracy (I forget the exact terminology) of a floating point number in base 10.

See: http://www.cplusplus.com/reference/std/limits/numeric_limits.html
For details about other attributes.

You can have multiple CTEs in one query, as well as reuse a CTE:

WITH    cte1 AS
        (
        SELECT  1 AS id
        ),
        cte2 AS
        (
        SELECT  2 AS id
        )
SELECT  *
FROM    cte1
UNION ALL
SELECT  *
FROM    cte2
UNION ALL
SELECT  *
FROM    cte1

Note, however, that SQL Server may reevaluate the CTE each time it is accessed, so if you are using values like RAND(), NEWID() etc., they may change between the CTE calls.

Some of the other posts are confused about which dimension is which. Here's an NUNIT test that shows how 2D arrays work in C#

[Test]
public void ArraysAreRowMajor()
{
    var myArray = new int[2,3]
        {
            {1, 2, 3},
            {4, 5, 6}
        };

    int rows = myArray.GetLength(0);
    int columns = myArray.GetLength(1);
    Assert.AreEqual(2,rows);
    Assert.AreEqual(3,columns);
    Assert.AreEqual(1,myArray[0,0]);
    Assert.AreEqual(2,myArray[0,1]);
    Assert.AreEqual(3,myArray[0,2]);
    Assert.AreEqual(4,myArray[1,0]);
    Assert.AreEqual(5,myArray[1,1]);
    Assert.AreEqual(6,myArray[1,2]);
}

I'd like to propose

np.min(np.append(np.where(aa>5)[0],np.inf))

This will return the smallest index where the condition is met, while returning infinity if the condition is never met (and where returns an empty array).

Another way to do it on Ubuntu 18.0.4

sudo /usr/share/kibana/bin/kibana --version

Do you control the excel worksheet in anyway? Is there a template the users have for giving you the input? If so, you can have code format the input cells for you.

If you take a look at the result of valeur <= 0.6, you can see what’s causing this ambiguity:

>>> valeur <= 0.6
array([ True, False, False, False], dtype=bool)

So the result is another array that has in this case 4 boolean values. Now what should the result be? Should the condition be true when one value is true? Should the condition be true only when all values are true?

That’s exactly what numpy.any and numpy.all do. The former requires at least one true value, the latter requires that all values are true:

>>> np.any(valeur <= 0.6)
True
>>> np.all(valeur <= 0.6)
False

• It's kinda pointless without arithmetic methods like add() and multiply(), etc.
• You should definitely override equals() and hashCode().
• You should either add a method to normalize the fraction, or do it automatically. Think about whether you want 1/2 and 2/4 to be considered the same or not - this has implications for the equals(), hashCode() and compareTo() methods.

In cryptography there are two types of algorithms used:

Symmetric algorithms

A single key is used to encrypt data. When encrypted with the key, the data can be decrypted using the same key. If, for example, Mary encrypts a message using the key "my-secret" and sends it to John, he will be able to decrypt the message correctly with the same key "my-secret".

Asymmetric algorithms

Two keys are used to encrypt and decrypt messages. While one key(public) is used to encrypt the message, the other key(private) can only be used to decrypt it. So, John can generate both public and private keys, then send only the public key to Mary to encrypt her message. The message can only be decrypted using the private key.

HS256 and RS256 Scenario

These algorithms are NOT used to encrypt/decryt data. Rather they are used to verify the origin or the authenticity of the data. When Mary needs to send an open message to Jhon and he needs to verify that the message is surely from Mary, HS256 or RS256 can be used.

HS256 can create a signature for a given sample of data using a single key. When the message is transmitted along with the signature, the receiving party can use the same key to verify that the signature matches the message.

RS256 uses pair of keys to do the same. A signature can only be generated using the private key. And the public key has to be used to verify the signature. In this scenario, even if Jack finds the public key, he cannot create a spoof message with a signature to impersonate Mary.

Put this code in your Activity's onCreate method. This helped me.

I faced the same issue recently. I found a solution that apparently works for all devices. You can't do async focus programmatically but you can switch focus to your target input when some other input is already focused. So what you need to do is create, hide, append to DOM & focus a fake input on trigger event and, when the async action completes, just call focus again on the target input. Here's an example snippet - run it on your mobile.

edit:

Here's a fiddle with the same code. Apparently you can't run attached snippets on mobiles (or I'm doing something wrong).

As others have suggested, you can directly write a 2-dimensional array into a Range on sheet, however if your array is single-dimensional then you have two options:

1. Convert your 1D array into a 2D array first, then print it on sheet (as a Range).
2. Convert your 1D array into a string and print it in a single cell (as a String).

Here is an example depicting both options:

Sub PrintArrayIn1Cell(myArr As Variant, cell As Range)
    cell = Join(myArr, ",")
End Sub
Sub PrintArrayAsRange(myArr As Variant, cell As Range)
    cell.Resize(UBound(myArr, 1), UBound(myArr, 2)) = myArr
End Sub
Sub TestPrintArrayIntoSheet()  '2dArrayToSheet
    Dim arr As Variant
    arr = Split("a  b  c", "  ")

    'Printing in ONE-CELL: To print all array-elements as a single string separated by comma (a,b,c):
    PrintArrayIn1Cell arr, [A1]

    'Printing in SEPARATE-CELLS: To print array-elements in separate cells:
    Dim arr2D As Variant
    arr2D = Application.WorksheetFunction.Transpose(arr) 'convert a 1D array into 2D array
    PrintArrayAsRange arr2D, Range("B1:B3")
End Sub

Note: Transpose will render column-by-column output, to get row-by-row output transpose it again - hope that makes sense.

Worked for me , can try with the same

<ProgressBar
    android:id="@+id/determinateBar"
    android:indeterminateOnly="true"
    android:indeterminateDrawable="@android:drawable/progress_indeterminate_horizontal"
    android:indeterminateDuration="10"
    android:indeterminateBehavior="repeat"
    android:progressBackgroundTint="#208afa"
    android:progressBackgroundTintMode="multiply"
    android:minHeight="24dip"
    android:maxHeight="24dip"
    android:layout_width="match_parent"
    android:layout_height="10dp"
    android:visibility="visible"/>

I wanted to add a warning because I noticed that some of the simple solutions omit the InvokeRequired check.

I noticed that if your code executes before the window handle of the control has been created (e.g. before the form is shown), Invoke throws an exception. So I recommend always checking on InvokeRequired before calling Invoke or BeginInvoke.

Here's a simple script that wraps up using the dd approach mentioned here:

extract_chars.sh

#!/usr/bin/env bash

function show_help()
{
  IT="
extracts characters X to Y from stdin or FILE
usage: X Y {FILE}

e.g. 

2 10 /tmp/it     => extract chars 2-10 from /tmp/it
EOF
  "
  echo "$IT"
  exit
}

if [ "$1" == "help" ]
then
  show_help
fi
if [ -z "$1" ]
then
  show_help
fi

FROM=$1
TO=$2
COUNT=`expr $TO - $FROM + 1`

if [ -z "$3" ]
then
  dd skip=$FROM count=$COUNT bs=1 2>/dev/null
else
  dd skip=$FROM count=$COUNT bs=1 if=$3 2>/dev/null 
fi

This function creates a temporary form, then send data using jQuery :

function postToIframe(data,url,target){
    $('body').append('<form action="'+url+'" method="post" target="'+target+'" id="postToIframe"></form>');
    $.each(data,function(n,v){
        $('#postToIframe').append('<input type="hidden" name="'+n+'" value="'+v+'" />');
    });
    $('#postToIframe').submit().remove();
}

target is the 'name' attr of the target iFrame, and data is a JS object :

data={last_name:'Smith',first_name:'John'}

Try this Javascript (jquery) code. Its an ajax request to an external URL. Use the callback function to fire any code:

<script type="text/javascript">
$(function() {
  $('form').submit(function(){
    $.post('http://example.com/upload', function() {
      window.location = 'http://google.com';
    });
    return false;
  });
});
</script>

Late reply but for.databse-date-type the following line works.

SELECT to_date(t.given_date,'DD/MM/RRRR') response_date FROM Table T

given_date's column type is Date

Super simple in-place assignment: df['new'] = 0

For in-place modification, perform direct assignment. This assignment is broadcasted by pandas for each row.

df = pd.DataFrame('x', index=range(4), columns=list('ABC'))
df

   A  B  C
0  x  x  x
1  x  x  x
2  x  x  x
3  x  x  x

df['new'] = 'y'
# Same as,
# df.loc[:, 'new'] = 'y'
df

   A  B  C new
0  x  x  x   y
1  x  x  x   y
2  x  x  x   y
3  x  x  x   y

Note for object columns

If you want to add an column of empty lists, here is my advice:

• Consider not doing this. object columns are bad news in terms of performance. Rethink how your data is structured.
• Consider storing your data in a sparse data structure. More information: sparse data structures

• If you must store a column of lists, ensure not to copy the same reference multiple times.

  # Wrong
  df['new'] = [[]] * len(df)
  # Right
  df['new'] = [[] for _ in range(len(df))]
  

Generating a copy: df.assign(new=0)

If you need a copy instead, use DataFrame.assign:

df.assign(new='y')

   A  B  C new
0  x  x  x   y
1  x  x  x   y
2  x  x  x   y
3  x  x  x   y

And, if you need to assign multiple such columns with the same value, this is as simple as,

c = ['new1', 'new2', ...]
df.assign(**dict.fromkeys(c, 'y'))

   A  B  C new1 new2
0  x  x  x    y    y
1  x  x  x    y    y
2  x  x  x    y    y
3  x  x  x    y    y

Multiple column assignment

Finally, if you need to assign multiple columns with different values, you can use assign with a dictionary.

c = {'new1': 'w', 'new2': 'y', 'new3': 'z'}
df.assign(**c)

   A  B  C new1 new2 new3
0  x  x  x    w    y    z
1  x  x  x    w    y    z
2  x  x  x    w    y    z
3  x  x  x    w    y    z

In my side, it is because POSTMAN setting issue, but I don't know why, maybe I copy a query from other. I simply create a new request in POSTMAN and run it, it works.

@Entity(name = "someThing") => this name will be used to name the Entity
@Table(name = "someThing")  => this name will be used to name a table in DB

So, in the first case your table and entity will have the same name, that will allow you to access your table with the same name as the entity while writing HQL or JPQL.

And in second case while writing queries you have to use the name given in @Entity and the name given in @Table will be used to name the table in the DB.

So in HQL your someThing will refer to otherThing in the DB.

You can use this piece of code:

  <iframe src="http://example.com" frameborder="0" style="overflow:hidden;overflow-x:hidden;overflow-y:hidden;height:100%;width:100%;position:absolute;top:0%;left:0px;right:0px;bottom:0px" height="100%" width="100%"></iframe>

Yes, it's in the Debugging section of the properties page of the project.

In Visual Studio since 2008: right-click the project, choose Properties, go to the Debugging section -- there is a box for "Command Arguments". (Tip: not solution, but project).

I came across a similar need this morning: how to convert a relative path into an absolute path inside a Windows command script.

The following did the trick:

@echo off

set REL_PATH=..\..\
set ABS_PATH=

rem // Save current directory and change to target directory
pushd %REL_PATH%

rem // Save value of CD variable (current directory)
set ABS_PATH=%CD%

rem // Restore original directory
popd

echo Relative path: %REL_PATH%
echo Maps to path: %ABS_PATH%

You could use an image submit button:

<input type="image" src="images/login.jpg" alt="Submit Form" />

Using a supposed name property as the map key:

for (Product p: productList) { s.put(p.getName(), p); }

Note that if you're targeting node.js you can use Buffer.from(string).length:

var str = "\u2620"; // => "?"
str.length; // => 1 (character)
Buffer.from(str).length // => 3 (bytes)

I can't comment on the accepted answer, due to low reputation. However, I would like to add, this behavior is by design. The NodeManager is killing your container. It sounds like you are trying to use hadoop streaming which is running as a child process of the map-reduce task. The NodeManager monitors the entire process tree of the task and if it eats up more memory than the maximum set in mapreduce.map.memory.mb or mapreduce.reduce.memory.mb respectively, we would expect the Nodemanager to kill the task, otherwise your task is stealing memory belonging to other containers, which you don't want.

Fast-forward almost 9 years since this was first asked, and in the world of .NET Core and .NET Standard, it seems the most common options we have for URL-encoding are WebUtility.UrlEncode (under System.Net) and Uri.EscapeDataString. Judging by the most popular answer here and elsewhere, Uri.EscapeDataString appears to be preferable. But is it? I did some analysis to understand the differences and here's what I came up with:

• WebUtility.UrlEncode encodes space as +; Uri.EscapeDataString encodes it as %20.
• Uri.EscapeDataString percent-encodes !, (, ), and *; WebUtility.UrlEncode does not.
• WebUtility.UrlEncode percent-encodes ~; Uri.EscapeDataString does not.
• Uri.EscapeDataString throws a UriFormatException on strings longer than 65,520 characters; WebUtility.UrlEncode does not. (A more common problem than you might think, particularly when dealing with URL-encoded form data.)
• Uri.EscapeDataString throws a UriFormatException on the high surrogate characters; WebUtility.UrlEncode does not. (That's a UTF-16 thing, probably a lot less common.)

For URL-encoding purposes, characters fit into one of 3 categories: unreserved (legal in a URL); reserved (legal in but has special meaning, so you might want to encode it); and everything else (must always be encoded).

According to the RFC, the reserved characters are: :/?#[]@!$&'()*+,;=

And the unreserved characters are alphanumeric and -._~

The Verdict

Uri.EscapeDataString clearly defines its mission: %-encode all reserved and illegal characters. WebUtility.UrlEncode is more ambiguous in both definition and implementation. Oddly, it encodes some reserved characters but not others (why parentheses and not brackets??), and stranger still it encodes that innocently unreserved ~ character.

Therefore, I concur with the popular advice - use Uri.EscapeDataString when possible, and understand that reserved characters like / and ? will get encoded. If you need to deal with potentially large strings, particularly with URL-encoded form content, you'll need to either fall back on WebUtility.UrlEncode and accept its quirks, or otherwise work around the problem.

EDIT: I've attempted to rectify ALL of the quirks mentioned above in Flurl via the Url.Encode, Url.EncodeIllegalCharacters, and Url.Decode static methods. These are in the core package (which is tiny and doesn't include all the HTTP stuff), or feel free to rip them from the source. I welcome any comments/feedback you have on these.

Here's the code I used to discover which characters are encoded differently:

var diffs =
    from i in Enumerable.Range(0, char.MaxValue + 1)
    let c = (char)i
    where !char.IsHighSurrogate(c)
    let diff = new {
        Original = c,
        UrlEncode = WebUtility.UrlEncode(c.ToString()),
        EscapeDataString = Uri.EscapeDataString(c.ToString()),
    }
    where diff.UrlEncode != diff.EscapeDataString
    select diff;

foreach (var diff in diffs)
    Console.WriteLine($"{diff.Original}\t{diff.UrlEncode}\t{diff.EscapeDataString}");

How to include images in your app

1. Create an assets/images folder

• This should be located in the root of your project, in the same folder as your pubspec.yaml file.
• In Android Studio you can right click in the Project view
• You don't have to call it assets or images. You don't even need to make images a subfolder. Whatever name you use, though, is what you will regester in the pubspec.yaml file.

2. Add your image to the new folder

• You can just copy your image into assets/images. The relative path of lake.jpg, for example, would be assets/images/lake.jpg.

3. Register the assets folder in pubspec.yaml

• Open the pubspec.yaml file that is in the root of your project.

• Add an assets subsection to the flutter section like this:

    flutter:
      assets:
        - assets/images/lake.jpg
  

• If you have multiple images that you want to include then you can leave off the file name and just use the directory name (include the final /):

    flutter:
      assets:
        - assets/images/
  

4. Use the image in code

• Get the asset in an Image widget with Image.asset('assets/images/lake.jpg').

• The entire main.dart file is here:

    import 'package:flutter/material.dart';
  
    void main() => runApp(MyApp());
  
    class MyApp extends StatelessWidget {
      @override
      Widget build(BuildContext context) {
        return MaterialApp(
          home: Scaffold(
            appBar: AppBar(
              title: Text("Image from assets"),
            ),
            body: Image.asset('assets/images/lake.jpg'), //   <--- image
          ),
        );
      }
    }
  

5. Restart your app

When making changes to pubspec.yaml I find that I often need to completely stop my app and restart it again, especially when adding assets. Otherwise I get a crash.

Running the app now you should have something like this:

Further reading

• See the documentation for how to do things like provide alternate images for different densities.

Videos

The first video here goes into a lot of detail about how to include images in your app. The second video covers more about how to adjust how they look.

• Flutter Tutorial - 2/2 Image - Deep Dive

You are asking to replace the character "?" but for me that is coming through as three characters 'ï', '¿' and '½'. This might be your problem... If you are using Java prior to Java 1.5 then you only get the UCS-2 characters, that is only the first 65K UTF-8 characters. Based on other comments, it is most likely that the character that you are looking for is '?', that is the Unicode replacement character. This is the character that is "used to replace an incoming character whose value is unknown or unrepresentable in Unicode".

Actually, looking at the comment from Kathy, the other issue that you might be having is that javac is not interpreting your .java file as UTF-8, assuming that you are writing it in UTF-8. Try using:

javac -encoding UTF-8 xx.java

Or, modify your source code to do:

String.replaceAll("\uFFFD", "");

var array = [[1, "grape", 42], [2, "fruit", 9]];

array.sort(function(a, b)
{
    // a and b will here be two objects from the array
    // thus a[1] and b[1] will equal the names

    // if they are equal, return 0 (no sorting)
    if (a[1] == b[1]) { return 0; }
    if (a[1] > b[1])
    {
        // if a should come after b, return 1
        return 1;
    }
    else
    {
        // if b should come after a, return -1
        return -1;
    }
});

The sort function takes an additional argument, a function that takes two arguments. This function should return -1, 0 or 1 depending on which of the two arguments should come first in the sorting. More info.

I also fixed a syntax error in your multidimensional array.

You have several options for iterating over a dictionary.

If you iterate over the dictionary itself (for team in league), you will be iterating over the keys of the dictionary. When looping with a for loop, the behavior will be the same whether you loop over the dict (league) itself, or league.keys():

for team in league.keys():
    runs_scored, runs_allowed = map(float, league[team])

You can also iterate over both the keys and the values at once by iterating over league.items():

for team, runs in league.items():
    runs_scored, runs_allowed = map(float, runs)

You can even perform your tuple unpacking while iterating:

for team, (runs_scored, runs_allowed) in league.items():
    runs_scored = float(runs_scored)
    runs_allowed = float(runs_allowed)

You can do this another way by checking the array length

<div *ngIf="stuff.length>0">
  <div *ngFor="let thing of stuff">
    {{log(thing)}}
    <span>{{thing.name}}</span>
  </div>
</div>

Hint: If you have more than one connection property then separate them with:

&

To give you somthing like:

url="jdbc:mysql://localhost/glyndwr?autoReconnect=true&allowMultiQueries=true"

I hope this helps some one.

As mentioned, Java isn't able to delete a folder that contains files, so first delete the files and then the folder.

Here's a simple example to do this:

import org.apache.commons.io.FileUtils;



// First, remove files from into the folder 
FileUtils.cleanDirectory(folder/path);

// Then, remove the folder
FileUtils.deleteDirectory(folder/path);

Or:

FileUtils.forceDelete(new File(destination));

A couple of contributions suggested that arrays in python are represented by lists. This is incorrect. Python has an independent implementation of array() in the standard library module array "array.array()" hence it is incorrect to confuse the two. Lists are lists in python so be careful with the nomenclature used.

list_01 = [4, 6.2, 7-2j, 'flo', 'cro']

list_01
Out[85]: [4, 6.2, (7-2j), 'flo', 'cro']

There is one very important difference between list and array.array(). While both of these objects are ordered sequences, array.array() is an ordered homogeneous sequences whereas a list is a non-homogeneous sequence.

I have tried all suggestions and found my own simple solution.

The problem is that codes written in external environment like C need compiler. Look for its own VS environment, i.e. VS 2008.

Currently my machine runs VS 2012 and faces Unable to find vcvarsall.bat. I studied codes that i want to install to find the VS version. It was VS 2008. i have add to system variable VS90COMNTOOLS as variable name and gave the value of VS120COMNTOOLS.

You can find my step by step solution below:

1. Right click on My Computer.
2. Click Properties
3. Advanced system settings
4. Environment variables
5. Add New system variable
6. Enter VS90COMNTOOLS to the variable name
7. Enter the value of current version to the new variable.
8. Close all windows

Now open a new session and pip install your-package

If you are using ModelViewSet, well actually you are done! It handles every things for you! You just need to put the field in your ModelSerializer and set content-type=multipart/form-data; in your client.

BUT as you know you can not send files in json format. (when content-type is set to application/json in your client). Unless you use Base64 format.

So you have two choices:

• let ModelViewSet and ModelSerializer handle the job and send the request using content-type=multipart/form-data;
• set the field in ModelSerializer as Base64ImageField (or) Base64FileField and tell your client to encode the file to Base64 and set the content-type=application/json

Alamofire ~5.2 and Swift 5

You can structure your parameter data

Work with fake json api

struct Parameter: Encodable {
     let token: String = "xxxxxxxxxx"
     let data: Dictionary = [
        "id": "personNickname",
        "email": "internetEmail",
        "gender": "personGender",
     ]
}

 let parameters = Parameter()

 AF.request("https://app.fakejson.com/q", method: .post, parameters: parameters).responseJSON { response in
            print(response)
        }

The specific value in your database isn't what you should be focusing on. This is likely the result of an attacker fuzzing your system to see if it is vulnerable to a set of standard attacks, instead of a targeted attack exploiting a known vulnerability.

You should instead focus on ensuring that your application is secure against these types of attacks; OWASP is a good resource for this.

If you're using parameterized queries to access the database, then you're secure against Sql injection, unless you're using dynamic Sql in the backend as well.

If you're not doing this, you're vulnerable and you should resolve this immediately.

Also, you should consider performing some sort of validation of e-mail addresses.

You need to add a reference inside the window tag. Something like:

xmlns:controls="clr-namespace:YourCustomNamespace.Controls;assembly=YourAssemblyName"

(When you add xmlns:controls=" intellisense should kick in to make this bit easier)

Then you can add the control with:

<controls:CustomControlClassName ..... />

I tweaked @markrushakoff's answer to make it a callable function:

function yesNo {
  # Prompts user with $1, returns true if response starts with y or Y or is empty string
  read -e -p "
$1 [Y/n] " YN

  [[ "$YN" == y* || "$YN" == Y* || "$YN" == "" ]]
}

Use it like this:

$ if yesNo "asfd"; then echo "true"; else echo "false"; fi

asfd [Y/n] y
true

$ if yesNo "asfd"; then echo "true"; else echo "false"; fi

asfd [Y/n] Y
true

$ if yesNo "asfd"; then echo "true"; else echo "false"; fi

asfd [Y/n] yes
true

$ if yesNo "asfd"; then echo "true"; else echo "false"; fi

asfd [Y/n]
true

$ if yesNo "asfd"; then echo "true"; else echo "false"; fi

asfd [Y/n] n
false

$ if yesNo "asfd"; then echo "true"; else echo "false"; fi

asfd [Y/n] ddddd
false

Here is a more complex version that provides for a specified default value:

function toLowerCase {
  echo "$1" | tr '[:upper:]' '[:lower:]'
}

function yesNo {
  # $1: user prompt
  # $2: default value (assumed to be Y if not specified)
  # Prompts user with $1, using default value of $2, returns true if response starts with y or Y or is empty string

  local DEFAULT=yes
  if [ "$2" ]; then local DEFAULT="$( toLowerCase "$2" )"; fi
  if [[ "$DEFAULT" == y* ]]; then
    local PROMPT="[Y/n]"
  else
    local PROMPT="[y/N]"
  fi
  read -e -p "
$1 $PROMPT " YN

  YN="$( toLowerCase "$YN" )"
  { [ "$YN" == "" ] && [[ "$PROMPT" = *Y* ]]; } || [[ "$YN" = y* ]]
}

Use it like this:

$ if yesNo "asfd" n; then echo "true"; else echo "false"; fi

asfd [y/N]
false

$ if yesNo "asfd" n; then echo "true"; else echo "false"; fi

asfd [y/N] y
true

$ if yesNo "asfd" y; then echo "true"; else echo "false"; fi

asfd [Y/n] n
false

Quite easy

$timestring = '09:15:00';
echo date('h:i:s', strtotime($timestring) + (15 * 60));

Click event Bubbles, now what is meant by bubbling, a good point to starts is here. you can use event.stopPropagation(), if you don't want that event should propagate further.

Also a good link to refer on MDN

Try to follow the advice you see on the screen, and first reset your master's HEAD to the commit it expects.

git update-ref refs/heads/master b918ac16a33881ce00799bea63d9c23bf7022d67

Then, abort the rebase again.

This isn't a direct answer but may provide a more efficient alternative for your consideration. Which is that Google Sheets has several built in Regex Functions these can be very convenient and help circumvent some of the technical procedures in Excel. Obviously there are some advantages to using Excel on your PC but for the large majority of users Google Sheets will offer an identical experience and may offer some benefits in portability and sharing of documents.

They offer

REGEXEXTRACT: Extracts matching substrings according to a regular expression.

REGEXREPLACE: Replaces part of a text string with a different text string using regular expressions.

SUBSTITUTE: Replaces existing text with new text in a string.

REPLACE: Replaces part of a text string with a different text string.

You can type these directly into a cell like so and will produce whatever you'd like

=REGEXMATCH(A2, "[0-9]+")

They also work quite well in combinations with other functions such as IF statements like so:

=IF(REGEXMATCH(E8,"MiB"),REGEXEXTRACT(E8,"\d*\.\d*|\d*")/1000,IF(REGEXMATCH(E8,"GiB"),REGEXEXTRACT(E8,"\d*\.\d*|\d*"),"")

Hopefully this provides a simple workaround for users who feel taunted by the VBS component of Excel.

If you only want to perform some specific operations by your second SP and do not require values back from the SP then simply do:

Exec secondSPName  @anyparams

Else, if you need values returned by your second SP inside your first one, then create a temporary table variable with equal numbers of columns and with same definition of column return by second SP. Then you can get these values in first SP as:

Insert into @tep_table
Exec secondSPName @anyparams

Update:

To pass parameter to second sp, do this:

Declare @id ID_Column_datatype 
Set @id=(Select id from table_1 Where yourconditions)

Exec secondSPName @id

Update 2:

Suppose your second sp returns Id and Name where type of id is int and name is of varchar(64) type.

now, if you want to select these values in first sp then create a temporary table variable and insert values into it:

Declare @tep_table table
(
  Id int,
  Name varchar(64)
)
Insert into @tep_table
Exec secondSP

Select * From @tep_table

This will return you the values returned by second SP.

Hope, this clear all your doubts.

I find this works better:

SELECT type, *
FROM sys.objects
WHERE OBJECT_DEFINITION(object_id) LIKE '%' + @ObjectName + '%'
AND type IN ('V')
ORDER BY name

Filtering VIEW_DEFINTION inside INFORMATION_SCHEMA.VIEWS is giving me quite a few false positives.

Note: This code is untested

Define a record for your refCursor return type, call it rec. For example:

TYPE MyRec IS RECORD (col1 VARCHAR2(10), col2 VARCHAR2(20), ...);  --define the record
rec MyRec;        -- instantiate the record

Once you have the refcursor returned from your procedure, you can add the following code where your comments are now:

LOOP
  FETCH refCursor INTO rec;
  EXIT WHEN refCursor%NOTFOUND;
  dbms_output.put_line(rec.col1||','||rec.col2||','||...);
END LOOP;

Here is an example using css3:

CSS:

html, body {
    height: 100%;
    margin: 0;
}
#wrap {
    padding: 10px;
    min-height: -webkit-calc(100% - 100px);     /* Chrome */
    min-height: -moz-calc(100% - 100px);     /* Firefox */
    min-height: calc(100% - 100px);     /* native */
}
.footer {
    position: relative;
    clear:both;
}

HTML:

<div id="wrap">
    body content....
</div>
<footer class="footer">
    footer content....
</footer>

jsfiddle

Update
As @Martin pointed, the ´position: relative´ is not mandatory on the .footer element, the same for clear:both. These properties are only there as an example. So, the minimum css necessary to stick the footer on the bottom should be:

html, body {
    height: 100%;
    margin: 0;
}
#wrap {
    min-height: -webkit-calc(100% - 100px);     /* Chrome */
    min-height: -moz-calc(100% - 100px);     /* Firefox */
    min-height: calc(100% - 100px);     /* native */
}

Also, there is an excellent article at css-tricks showing different ways to do this: https://css-tricks.com/couple-takes-sticky-footer/

Use the -ss option:

ffmpeg -ss 01:23:45 -i input -vframes 1 -q:v 2 output.jpg

• For JPEG output use -q:v to control output quality. Full range is a linear scale of 1-31 where a lower value results in a higher quality. 2-5 is a good range to try.

• The select filter provides an alternative method for more complex needs such as selecting only certain frame types, or 1 per 100, etc.

• Placing -ss before the input will be faster. See FFmpeg Wiki: Seeking and this excerpt from the ffmpeg cli tool documentation:

-ss position (input/output)

When used as an input option (before -i), seeks in this input file to position. Note the in most formats it is not possible to seek exactly, so ffmpeg will seek to the closest seek point before position. When transcoding and -accurate_seek is enabled (the default), this extra segment between the seek point and position will be decoded and discarded. When doing stream copy or when -noaccurate_seek is used, it will be preserved.

When used as an output option (before an output filename), decodes but discards input until the timestamps reach position.

position may be either in seconds or in hh:mm:ss[.xxx] form.

I stumbled over the same question and I've found a solution.

First make sure you upgrade to LESS 1.6 at least. You can use npm for that case.

Now you can use the following mixin:

.if (@condition, @property, @value) when (@condition = true){
     @{property}: @value;
 }

Since LESS 1.6 you are able to pass PropertyNames to Mixins as well. So for example you could just use:

.myHeadline {
   .if(@include-lineHeight,  line-height, '35px');
}

If @include-lineheight resolves to true LESS will print the line-height: 35px and it will skip the mixin if @include-lineheight is not true.

Here is the solution :

@media (min-width: 1200px) {
    .container{
        max-width: 970px;
    }
}

The advantage of doing this, versus customizing Bootstrap as in @Bastardo's answer, is that it doesn't change the Bootstrap file. For example, if using a CDN, you can still download most of Bootstrap from the CDN.

Unless you have some kind of really weird problem, keep it. The number of IPv6 sites is very small, but there are some and it will let you get to them even if you're at an IPv4 only location.

If it is causing you a problem, it's best to fix it. I've seen a number of people recommending removing it to solve problems. However, they're not actually solving the root cause of the issue. In all the cases I've seen, removing Teredo just happens to cause a side-effect that fixes their problem... :)

I realise this doesn't answer scrolling in a container but people are finding it useful so:

$('html,body').animate({scrollTop: some_element.offset().top});

We select both html and body because the document scroller could be on either and it is hard to determine which. For modern browsers you can get away with $(document.body).

Or, to go to the top of the page:

$('html,body').animate({scrollTop: 0});

Or without animation:

$(window).scrollTop(some_element.offset().top);

OR...

window.scrollTo(0, some_element.offset().top); // native equivalent (x, y)

I had a similar problem and I just modified the event handler to check the type of the variable. The type is only set after the user selects a value, not when the page is first loaded.

self.permissionChanged = function (l) {
    if (typeof l != 'undefined') {
        ...
    }
}

This seems to work for me.

While many options above function well, I found coercion of non-target variables to chr problematic. Using ifelse and grepl within lapply resolves this off-target effect (in limited testing). Using slarky's regular expression in grepl:

set.seed(42)
x1 <- sample(c("a","b"," ", "a a", NA), 10, TRUE)
x2 <- sample(c(rnorm(length(x1),0, 1), NA), length(x1), TRUE)

df <- data.frame(x1, x2, stringsAsFactors = FALSE)

The problem of coercion to character class:

df2 <- lapply(df, function(x) gsub("^$|^ $", NA, x))
lapply(df2, class)

$x1 [1] "character"

$x2 [1] "character"

Resolution with use of ifelse:

df3 <- lapply(df, function(x) ifelse(grepl("^$|^ $", x)==TRUE, NA, x))
lapply(df3, class)

$x1 [1] "character"

$x2 [1] "numeric"

You only need these CSS properties in .container class of Bootstrap and you can put inside him the normal grid system without someone content of the container will be out of him (without scroll-x in the viewport).

HTML:

<div class="container">
    <div class="row">
        <div class="col-xs-12">
            Your content here!
            ...    
        </div>
    </div>
    ... more rows
</div>

CSS:

/* Bootstrap custom */
.container{
    padding-left: 0rem;
    padding-right: 0rem;
    overflow: hidden;
}

When I was facing this issue I used to install OpenCV in pycharm installed package panel where we can find under the settings tab. Search "OpenCV-python" and install it in the installed package panel of right interpreter.

I’ve created a convenient script for that; pg_grant_read_to_db.sh. This script grants read-only privileges to a specified role on all tables, views and sequences in a database schema and sets them as default.

So with Angular 1.5.1 ( had existing app dependency on some other MEAN stack dependencies is why I'm not currently using 1.6.4 )

This works for me like the OP saying {{myVar === "two" ? "it's true" : "it's false"}}

{{vm.StateName === "AA" ? "ALL" : vm.StateName}}

The functions getElementById and getElementsByClassName are very specific, while querySelector and querySelectorAll are more elaborate. My guess is that they will actually have a worse performance.

Also, you need to check for the support of each function in the browsers you are targetting. The newer it is, the higher probability of lack of support or the function being "buggy".

I just needed to do this, but thought Steven's solution would be slow. This should hopefully use graphics HW. Create a category on UIImage:

- (UIImage *)imageByApplyingAlpha:(CGFloat) alpha {
    UIGraphicsBeginImageContextWithOptions(self.size, NO, 0.0f);

    CGContextRef ctx = UIGraphicsGetCurrentContext();
    CGRect area = CGRectMake(0, 0, self.size.width, self.size.height);

    CGContextScaleCTM(ctx, 1, -1);
    CGContextTranslateCTM(ctx, 0, -area.size.height);

    CGContextSetBlendMode(ctx, kCGBlendModeMultiply);

    CGContextSetAlpha(ctx, alpha);

    CGContextDrawImage(ctx, area, self.CGImage);

    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

    return newImage;
}

Adding to italo's answer, you can also do this using jQuery.

function isEllipsisActive($jQueryObject) {
    return ($jQueryObject.width() < $jQueryObject[0].scrollWidth);
}

Also, as Smoky pointed out, you may want to use jQuery outerWidth() instead of width().

function isEllipsisActive($jQueryObject) {
    return ($jQueryObject.outerWidth() < $jQueryObject[0].scrollWidth);
}

Saving a Keras model:

model = ...  # Get model (Sequential, Functional Model, or Model subclass)
model.save('path/to/location')

Loading the model back:

from tensorflow import keras
model = keras.models.load_model('path/to/location')

Using ADO (AnonJr already explained) and utilizing SQL is possibly the best option for fetching data from a closed workbook without opening that in conventional way. Please watch this VIDEO.

OTHERWISE, possibly GetObject(<filename with path>) is the most CONCISE way. Worksheets remain invisible, however will appear in project explorer window in VBE just like any other workbook opened in conventional ways.

Dim wb As Workbook

Set wb = GetObject("C:\MyData.xlsx")  'Worksheets will remain invisible, no new window appears in the screen
' your codes here
wb.Close SaveChanges:=False

If you want to read a particular sheet, need not even define a Workbook variable

Dim sh As Worksheet
Set sh = GetObject("C:\MyData.xlsx").Worksheets("MySheet")
' your codes here
sh.Parent.Close SaveChanges:=False 'Closes the associated workbook

Another suggestion is to check that you use a valid type for the auto-generated field. Remember that it doesn't work with String, but it works with Long:

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

@Constraints.Required
public String contents;

The above syntax worked for generating tables in MySQL using Hibernate as a JPA 2.0 provider.

If you're trying to just count how many of your cells in a range are not blank try this:

=COUNTA(range)

Example: (assume that it starts from A1 downwards):

---------    
Something 
---------
Something
---------

---------
Something
---------

---------
Something
---------

=COUNTA(A1:A6) returns 4 since there are two blank cells in there.

The decision of whether to use PUT or POST to create a resource on a server with an HTTP + REST API is based on who owns the URL structure. Having the client know, or participate in defining, the URL struct is an unnecessary coupling akin to the undesirable couplings that arose from SOA. Escaping types of couplings is the reason REST is so popular. Therefore, the proper method to use is POST. There are exceptions to this rule and they occur when the client wishes to retain control over the location structure of the resources it deploys. This is rare and likely means something else is wrong.

At this point some people will argue that if RESTful-URL's are used, the client does knows the URL of the resource and therefore a PUT is acceptable. After all, this is why canonical, normalized, Ruby on Rails, Django URLs are important, look at the Twitter API … blah blah blah. Those people need to understand there is no such thing as a Restful-URL and that Roy Fielding himself states that:

A REST API must not define fixed resource names or hierarchies (an obvious coupling of client and server). Servers must have the freedom to control their own namespace. Instead, allow servers to instruct clients on how to construct appropriate URIs, such as is done in HTML forms and URI templates, by defining those instructions within media types and link relations. [Failure here implies that clients are assuming a resource structure due to out-of band information, such as a domain-specific standard, which is the data-oriented equivalent to RPC's functional coupling].

http://roy.gbiv.com/untangled/2008/rest-apis-must-be-hypertext-driven

The idea of a RESTful-URL is actually a violation of REST as the server is in charge of the URL structure and should be free to decide how to use it to avoid coupling. If this confuses you read about the significance of self discovery on API design.

Using POST to create resources comes with a design consideration because POST is not idempotent. This means that repeating a POST several times does not guarantee the same behavior each time. This scares people into using PUT to create resources when they should not. They know it's wrong (POST is for CREATE) but they do it anyway because they don't know how to solve this problem. This concern is demonstrated in the following situation:

1. The client POST a new resource to the server.
2. The server processes the request and sends a response.
3. The client never receives the response.
4. The server is unaware the client has not received the response.
5. The client does not have a URL for the resource (therefore PUT is not an option) and repeats the POST.
6. POST is not idempotent and the server …

Step 6 is where people commonly get confused about what to do. However, there is no reason to create a kludge to solve this issue. Instead, HTTP can be used as specified in RFC 2616 and the server replies:

10.4.10 409 Conflict

The request could not be completed due to a conflict with the current state of the resource. This code is only allowed in situations where it is expected that the user might be able to resolve the conflict and resubmit the request. The response body SHOULD include enough

information for the user to recognize the source of the conflict. Ideally, the response entity would include enough information for the user or user agent to fix the problem; however, that might not be possible and is not required.

Conflicts are most likely to occur in response to a PUT request. For example, if versioning were being used and the entity being PUT included changes to a resource which conflict with those made by an earlier (third-party) request, the server might use the 409 response to indicate that it can’t complete the request. In this case, the response entity would likely contain a list of the differences between the two versions in a format defined by the response Content-Type.

Replying with a status code of 409 Conflict is the correct recourse because:

• Performing a POST of data which has an ID which matches a resource already in the system is “a conflict with the current state of the resource.”
• Since the important part is for the client to understand the server has the resource and to take appropriate action. This is a “situation(s) where it is expected that the user might be able to resolve the conflict and resubmit the request.”
• A response which contains the URL of the resource with the conflicting ID and the appropriate preconditions for the resource would provide “enough information for the user or user agent to fix the problem” which is the ideal case per RFC 2616.

Update based on release of RFC 7231 to Replace 2616

RFC 7231 is designed to replace 2616 and in Section 4.3.3 describes the follow possible response for a POST

If the result of processing a POST would be equivalent to a representation of an existing resource, an origin server MAY redirect the user agent to that resource by sending a 303 (See Other) response with the existing resource's identifier in the Location field. This has the benefits of providing the user agent a resource identifier and transferring the representation via a method more amenable to shared caching, though at the cost of an extra request if the user agent does not already have the representation cached.

It now may be tempting to simply return a 303 in the event that a POST is repeated. However, the opposite is true. Returning a 303 would only make sense if multiple create requests (creating different resources) return the same content. An example would be a "thank you for submitting your request message" that the client need not re-download each time. RFC 7231 still maintains in section 4.2.2 that POST is not to be idempotent and continues to maintain that POST should be used for create.

Client Upload

If you want to upload a single file with Python requests library, then requests lib supports streaming uploads, which allow you to send large files or streams without reading into memory.

with open('massive-body', 'rb') as f:
    requests.post('http://some.url/streamed', data=f)

Server Side

Then store the file on the server.py side such that save the stream into file without loading into the memory. Following is an example with using Flask file uploads.

@app.route("/upload", methods=['POST'])
def upload_file():
    from werkzeug.datastructures import FileStorage
    FileStorage(request.stream).save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
    return 'OK', 200

Or use werkzeug Form Data Parsing as mentioned in a fix for the issue of "large file uploads eating up memory" in order to avoid using memory inefficiently on large files upload (s.t. 22 GiB file in ~60 seconds. Memory usage is constant at about 13 MiB.).

@app.route("/upload", methods=['POST'])
def upload_file():
    def custom_stream_factory(total_content_length, filename, content_type, content_length=None):
        import tempfile
        tmpfile = tempfile.NamedTemporaryFile('wb+', prefix='flaskapp', suffix='.nc')
        app.logger.info("start receiving file ... filename => " + str(tmpfile.name))
        return tmpfile

    import werkzeug, flask
    stream, form, files = werkzeug.formparser.parse_form_data(flask.request.environ, stream_factory=custom_stream_factory)
    for fil in files.values():
        app.logger.info(" ".join(["saved form name", fil.name, "submitted as", fil.filename, "to temporary file", fil.stream.name]))
        # Do whatever with stored file at `fil.stream.name`
    return 'OK', 200

1.) Storage of database passwords Use some kind of hash with a salt and then alter the hash, obfuscate it, for example add a distinct value for each byte. That way your passwords a super secured against dictionary attacks and rainbow tables.

2.) To check if the password matches, create your hash for the password the user put in. Then perform a query against the database for the username and just check if the two password hashes are identical. If they are, give the user an authentication token.

The query should then look like this:

select hashedPassword from users where username=?

Then compare the password to the input.

Further questions?

Have a look at the below code snippet.

@RequestMapping(value="/Add/{type}")
public ModelAndView addForm(@PathVariable String type ){
    ModelAndView modelAndView = new ModelAndView();
    modelAndView.setViewName("addContent");
    modelAndView.addObject("typelist",contentPropertyDAO.getType() );
    modelAndView.addObject("property",contentPropertyDAO.get(type,0) );
    return modelAndView;
}

Hope it helps in constructing your code.

The key system must have several properties:

• very few keys must be valid
• valid keys must not be derivable even given everything the user has.
• a valid key on one system is not a valid key on another.

One solution that should give you these would be to use a public key signing scheme. Start with a "system hash" (say grab the macs on any NICs, sorted, and the CPU-ID info, plus some other stuff, concatenate it all together and take an MD5 of the result (you really don't want to be handling personally identifiable information if you don't have to)) append the CD's serial number and refuse to boot unless some registry key (or some datafile) has a valid signature for the blob. The user activates the program by shipping the blob to you and you ship back the signature.

Potential issues include that you are offering to sign practically anything so you need to assume someone will run a chosen plain text and/or chosen ciphertext attacks. That can be mitigated by checking the serial number provided and refusing to handle request from invalid ones as well as refusing to handle more than a given number of queries from a given s/n in an interval (say 2 per year)

I should point out a few things: First, a skilled and determined attacker will be able to bypass any and all security in the parts that they have unrestricted access to (i.e. everything on the CD), the best you can do on that account is make it harder to get illegitimate access than it is to get legitimate access. Second, I'm no expert so there could be serious flaws in this proposed scheme.

You could use the System.Reflection namespace with the Type.GetProperties() mehod:

PropertyInfo[] propertyInfos;
propertyInfos = typeof(MyClass).GetProperties(BindingFlags.Public|BindingFlags.Static);

in asp.net:

color_black = (Color)new ColorConverter().ConvertFromString("#FF76B3");

I know this is a Java question, but if you're using Kotlin you can do this quite nicely:

val uri = request.run {
    if (queryString.isNullOrBlank()) requestURI else "$requestURI?$queryString"
}

You cannot change the manifest or the resource in the signed-and-sealed APK, except through a software upgrade.

Here's a simple class that can display SVG images in a UIView

import UIKit

public class SVGImageView: UIView {
    private let webView = UIWebView()

    public init() {
        super.init(frame: .zero)
        webView.delegate = self
        webView.scrollView.isScrollEnabled = false
        webView.contentMode = .scaleAspectFit
        webView.backgroundColor = .clear
        addSubview(webView)
        webView.snp.makeConstraints { make in
            make.edges.equalTo(self)
        }
    }

    required public init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

    deinit {
        webView.stopLoading()
    }

    public func load(url: String) {
        webView.stopLoading()
        if let url = URL(string: fullUrl) {
            webView.loadRequest(URLRequest(url: url))
        }
    }
}

extension SVGImageView: UIWebViewDelegate {
    public func webViewDidFinishLoad(_ webView: UIWebView) {
        let scaleFactor = webView.bounds.size.width / webView.scrollView.contentSize.width
        if scaleFactor <= 0 {
            return
        }

        webView.scrollView.minimumZoomScale = scaleFactor
        webView.scrollView.maximumZoomScale = scaleFactor
        webView.scrollView.zoomScale = scaleFactor
    }
}

There is no difference until you compile to same target architecture. I suppose you are compiling for 32 bit architecture in both cases.

It's worth mentioning that OutOfMemoryException can also be raised if you get 2GB of memory allocated by a single collection in CLR (say List<T>) on both architectures 32 and 64 bit.

To be able to benefit from memory goodness on 64 bit architecture, you have to compile your code targeting 64 bit architecture. After that, naturally, your binary will run only on 64 bit, but will benefit from possibility having more space available in RAM.

I used a variant of Alex's - but needed to to convert the param appearing multiple times to an array. There seem to be many options. I didn't want rely on another library for something this simple. I suppose one of the other options posted here may be better - I adapted Alex's because of the straight forwardness.

parseQueryString = function() {
    var str = window.location.search;
    var objURL = {};

    // local isArray - defer to underscore, as we are already using the lib
    var isArray = _.isArray

    str.replace(
        new RegExp( "([^?=&]+)(=([^&]*))?", "g" ),
        function( $0, $1, $2, $3 ){

            if(objURL[ $1 ] && !isArray(objURL[ $1 ])){
                // if there parameter occurs more than once, convert to an array on 2nd
                var first = objURL[ $1 ]
                objURL[ $1 ] = [first, $3]
            } else if(objURL[ $1 ] && isArray(objURL[ $1 ])){
                // if there parameter occurs more than once, add to array after 2nd
                objURL[ $1 ].push($3)
            }
            else
            {
                // this is the first instance
                objURL[ $1 ] = $3;
            }

        }
    );
    return objURL;
};

Now you can change the primary dns (index=1), assuming that your interface is static (not using dhcp)

You can set your DNS servers statically even if you use DHCP to obtain your IP address.

Example under Windows 7 to add two DN servers, the command is as follows:

netsh interface ipv4 add dns "Local Area Connection" address=192.168.x.x index=1 netsh interface ipv4 add dns "Local Area Connection" address=192.168.x.x index=2

I made the same error using sudo for my installation. (oops)

brew install python
brew linkapps python
brew link --overwrite python 

This brought everything back to normal.

the default encoding of a HTTP POST is ISO-8859-1.

else you have to look at the Content-Type header that will then look like

Content-Type: application/x-www-form-urlencoded ; charset=UTF-8

You can maybe declare your form with

<form enctype="application/x-www-form-urlencoded;charset=UTF-8">

or

<form accept-charset="UTF-8">

to force the encoding.

The error SQLSTATE[HY000] [1040] Too many connections is an SQL error, and has to do with the sql server. There could be other applications connecting to the server. The server has a maximum available connections number.

If you have phpmyadmin, you can use the 'variables' tab to check what the setting is.

You can also query the status table like so:

show status like '%onn%';

Or some variance on that. check the manual for what variables there are

(be aware, 'connections' is not the current connections, check that link :) )

Short answer: in POST requests, values are sent in the "body" of the request. With web-forms they are most likely sent with a media type of application/x-www-form-urlencoded or multipart/form-data. Programming languages or frameworks which have been designed to handle web-requests usually do "The Right Thing™" with such requests and provide you with easy access to the readily decoded values (like $_REQUEST or $_POST in PHP, or cgi.FieldStorage(), flask.request.form in Python).

Now let's digress a bit, which may help understand the difference ;)

The difference between GET and POST requests are largely semantic. They are also "used" differently, which explains the difference in how values are passed.

GET (relevant RFC section)

When executing a GET request, you ask the server for one, or a set of entities. To allow the client to filter the result, it can use the so called "query string" of the URL. The query string is the part after the ?. This is part of the URI syntax.

So, from the point of view of your application code (the part which receives the request), you will need to inspect the URI query part to gain access to these values.

Note that the keys and values are part of the URI. Browsers may impose a limit on URI length. The HTTP standard states that there is no limit. But at the time of this writing, most browsers do limit the URIs (I don't have specific values). GET requests should never be used to submit new information to the server. Especially not larger documents. That's where you should use POST or PUT.

POST (relevant RFC section)

When executing a POST request, the client is actually submitting a new document to the remote host. So, a query string does not (semantically) make sense. Which is why you don't have access to them in your application code.

POST is a little bit more complex (and way more flexible):

When receiving a POST request, you should always expect a "payload", or, in HTTP terms: a message body. The message body in itself is pretty useless, as there is no standard (as far as I can tell. Maybe application/octet-stream?) format. The body format is defined by the Content-Type header. When using a HTML FORM element with method="POST", this is usually application/x-www-form-urlencoded. Another very common type is multipart/form-data if you use file uploads. But it could be anything, ranging from text/plain, over application/json or even a custom application/octet-stream.

In any case, if a POST request is made with a Content-Type which cannot be handled by the application, it should return a 415 status-code.

Most programming languages (and/or web-frameworks) offer a way to de/encode the message body from/to the most common types (like application/x-www-form-urlencoded, multipart/form-data or application/json). So that's easy. Custom types require potentially a bit more work.

Using a standard HTML form encoded document as example, the application should perform the following steps:

1. Read the Content-Type field
2. If the value is not one of the supported media-types, then return a response with a 415 status code
3. otherwise, decode the values from the message body.

Again, languages like PHP, or web-frameworks for other popular languages will probably handle this for you. The exception to this is the 415 error. No framework can predict which content-types your application chooses to support and/or not support. This is up to you.

PUT (relevant RFC section)

A PUT request is pretty much handled in the exact same way as a POST request. The big difference is that a POST request is supposed to let the server decide how to (and if at all) create a new resource. Historically (from the now obsolete RFC2616 it was to create a new resource as a "subordinate" (child) of the URI where the request was sent to).

A PUT request in contrast is supposed to "deposit" a resource exactly at that URI, and with exactly that content. No more, no less. The idea is that the client is responsible to craft the complete resource before "PUTting" it. The server should accept it as-is on the given URL.

As a consequence, a POST request is usually not used to replace an existing resource. A PUT request can do both create and replace.

Side-Note

There are also "path parameters" which can be used to send additional data to the remote, but they are so uncommon, that I won't go into too much detail here. But, for reference, here is an excerpt from the RFC:

Aside from dot-segments in hierarchical paths, a path segment is considered opaque by the generic syntax. URI producing applications often use the reserved characters allowed in a segment to delimit scheme-specific or dereference-handler-specific subcomponents. For example, the semicolon (";") and equals ("=") reserved characters are often used to delimit parameters and parameter values applicable to that segment. The comma (",") reserved character is often used for similar purposes. For example, one URI producer might use a segment such as "name;v=1.1" to indicate a reference to version 1.1 of "name", whereas another might use a segment such as "name,1.1" to indicate the same. Parameter types may be defined by scheme-specific semantics, but in most cases the syntax of a parameter is specific to the implementation of the URIs dereferencing algorithm.

After all files have been added, the next step is a "git commit".

"git status" will suggest what to do: files yet to add are listed at the bottom, and once they are all done, it will suggest a commit at the top, where it explains the merge status of the current branch.

Is a simple MAYUS word. verify the log.

if you have xcopy, you can use the /E param, which will copy directories and subdirectories and the files within them, including maintaining the directory structure for empty directories

xcopy [source] [destination] /E

If you are using zsh you can run:

setopt histignorespace

After this is set, each command starting with a space will be excluded from history.

You can use aliases in .zshrc to turn this on/off:

# Toggle ignore-space. Useful when entering passwords.
alias history-ignore-space-on='\
setopt hist_ignore_space;\
echo "Commands starting with space are now EXCLUDED from history."'

alias history-ignore-space-off='\
unsetopt hist_ignore_space;\
echo "Commands starting with space are now ADDED to history."'

try

<img src="https://cdn.glitch.com/0e4d1ff3-5897-47c5-9711-d026c01539b8%2Fbddfd6e4434f42662b009295c9bab86e.gif?v=1573157191712" alt="this slowpoke moves"  width="250" alt="404 image"/>

and switch the src with your source. If the alt pops up, try a different url. If it doesn't work, restart your computer or switch your browser.

Most answers are fairly old, so it might have not been possible back then, but there actually is a solution that satisfies all the possible use-cases.

So right know the answers are:

• Not providing a real Spring component (the factory design)
• or does not fit every situation (using @Value you have to have the value in a configuration file somewhere)

The solution to solve those issues is to create the object manually using the ApplicationContext:

@Component
public class MyConstructorClass
{
    String var;

    public MyConstructorClass() {}
    public MyConstructorClass(String constrArg) {
        this.var = var;
    }
}

@Service
public class MyBeanService implements ApplicationContextAware
{
    private static ApplicationContext applicationContext;

    MyConstructorClass myConstructorClass;

    public MyBeanService()
    {
        // Creating the object manually
        MyConstructorClass myObject = new MyConstructorClass("hello world");
        // Initializing the object as a Spring component
        AutowireCapableBeanFactory factory = applicationContext.getAutowireCapableBeanFactory();
        factory.autowireBean(myObject);
        factory.initializeBean(myObject, myObject.getClass().getSimpleName());
    }

    @Override
    public void setApplicationContext(ApplicationContext context) throws BeansException {
        applicationContext = context;
    }
}

This is a cool solution because:

• It gives you access to all the Spring functionalities on your object (@Autowired obviously, but also @Async for example),
• You can use any source for your constructor arguments (configuration file, computed value, hard-coded value, ...),
• It only requires you to add a few lines of code without having to change anything.
• It can also be used to dynamically create a unknown number of instances of a Spring-managed class (I'm using it to create multiple asynchronous executors on the fly for example)

The only thing to keep in mind is that you have to have a constructor that takes no arguments (and that can be empty) in the class you want to instantiate (or an @Autowired constructor if you need it).

I found this shorter and much better:

    if(varName !== (undefined || null)) { //do something }

Error parsing XML: unbound prefix

Resource '/playteddy/res' does not exist.

I got the above two errors and finally I solved it.

Right click your project -> properties -> java build path -> googleadmobadsdk (select and put it top), then you run and problem solved. It is solved my runtime error.

If you are in same WORKGROUP shutdown.exe /s /m \\<target-computer-name> should be enough shutdown /? for more, otherwise you need software to connect and control the target server.

UPDATE:

Seems shutdown.bat here is for shutting down apache-tomcat.

So, you might be interested to psexec or PuTTY: A Free Telnet/SSH Client

As native solution could be wmic

Example:

wmic /node:<target-computer-name> process call create "cmd.exe c:\\somefolder\\batch.bat"

In your example should be:

wmic /node:inidsoasrv01 process call create ^
    "cmd.exe D:\\apache-tomcat-6.0.20\\apache-tomcat-7.0.30\\bin\\shutdown.bat"

wmic /? and wmic /node /? for more

Call me simple but I just declared a Variant and split the responsetext from my REST GET on the quote comma quote between each item, then got the value I wanted by looking for the last quote with InStrRev. I'm sure that's not as elegant as some of the other suggestions but it works for me.

         varLines = Split(.responsetext, """,""")
        strType = Mid(varLines(8), InStrRev(varLines(8), """") + 1)

I wanted to add a comment but I have less than 50 pts so I can only "Answer". Be aware that if you use the "VisualTreeHelper" method to retrieve XAML "TextBlock" objects then it will also grab XAML "Button" objects. If you re-initialize the "TextBlock" object by writing to the Textblock.Text parameter then you will no longer be able to change the Button text using the Button.Content parameter. The Button will permanently show the text written to it from the Textblock.Text write action (from when it was retrieved --

foreach (TextBlock tb in FindVisualChildren<TextBlock>(window))
{
// do something with tb here
   tb.Text = ""; //this will overwrite Button.Content and render the 
                 //Button.Content{set} permanently disabled.
}

To work around this, you can try using a XAML "TextBox" and add methods (or Events) to mimic a XAMAL Button. XAML "TextBox" is not gathered by a search for "TextBlock".

Unique is a keyword used in the Create Table() directive to denote that a field will contain unique data, usually used for natural keys, foreign keys etc.

For example:

Create Table Employee(   
    Emp_PKey Int Identity(1, 1) Constraint PK_Employee_Emp_PKey Primary Key,  
    Emp_SSN Numeric Not Null Unique,  
    Emp_FName varchar(16),   
    Emp_LName varchar(16) 
)

i.e. Someone's Social Security Number would likely be a unique field in your table, but not necessarily the primary key.

Distinct is used in the Select statement to notify the query that you only want the unique items returned when a field holds data that may not be unique.

Select Distinct Emp_LName
From Employee

You may have many employees with the same last name, but you only want each different last name.

Obviously if the field you are querying holds unique data, then the Distinct keyword becomes superfluous.

Edit

This edit improves and explains the answer based on the comments.

var search = location.search.substring(1);
JSON.parse('{"' + decodeURI(search).replace(/"/g, '\\"').replace(/&/g, '","').replace(/=/g,'":"') + '"}')

Example

Parse abc=foo&def=%5Basf%5D&xyz=5 in five steps:

• decodeURI: abc=foo&def=[asf]&xyz=5
• Escape quotes: same, as there are no quotes
• Replace &: abc=foo","def=[asf]","xyz=5
• Replace =: abc":"foo","def":"[asf]","xyz":"5
• Suround with curlies and quotes: {"abc":"foo","def":"[asf]","xyz":"5"}

which is legal JSON.

An improved solution allows for more characters in the search string. It uses a reviver function for URI decoding:

var search = location.search.substring(1);
JSON.parse('{"' + search.replace(/&/g, '","').replace(/=/g,'":"') + '"}', function(key, value) { return key===""?value:decodeURIComponent(value) })

Example

search = "abc=foo&def=%5Basf%5D&xyz=5&foo=b%3Dar";

gives

Object {abc: "foo", def: "[asf]", xyz: "5", foo: "b=ar"}

Original answer

A one-liner:

JSON.parse('{"' + decodeURI("abc=foo&def=%5Basf%5D&xyz=5".replace(/&/g, "\",\"").replace(/=/g,"\":\"")) + '"}')
