Programs & Examples On #Microphone

I know it's an old question, but if someone is looking here again... see https://python-sounddevice.readthedocs.io/en/0.4.1/index.html .

It has a nice example "Input to Ouput Pass-Through" here https://python-sounddevice.readthedocs.io/en/0.4.1/examples.html#input-to-output-pass-through .

... and a lot of other examples as well ...

Just change moveCamera to animateCamera like below

Googlemap.animateCamera(CameraUpdateFactory.newLatLngZoom(locate, 16F))

When we use crontab or the deprecated /etc/rc.local file, we need a delay (e.g. sleep 10, depending on the machine) to make sure that system services are available. Usually, systemd (or upstart) is used to manage which services start when the system boots. You can try use the similar configuration for this:

# /etc/systemd/system/docker-compose-app.service

[Unit]
Description=Docker Compose Application Service
Requires=docker.service
After=docker.service

[Service]
Type=oneshot
RemainAfterExit=yes
WorkingDirectory=/srv/docker
ExecStart=/usr/local/bin/docker-compose up -d
ExecStop=/usr/local/bin/docker-compose down
TimeoutStartSec=0

[Install]
WantedBy=multi-user.target

Or, if you want run without the -d flag:

# /etc/systemd/system/docker-compose-app.service

[Unit]
Description=Docker Compose Application Service
Requires=docker.service
After=docker.service

[Service]
WorkingDirectory=/srv/docker
ExecStart=/usr/local/bin/docker-compose up
ExecStop=/usr/local/bin/docker-compose down
TimeoutStartSec=0
Restart=on-failure
StartLimitIntervalSec=60
StartLimitBurst=3

[Install]
WantedBy=multi-user.target

Change the WorkingDirectory parameter with your dockerized project path. And enable the service to start automatically:

systemctl enable docker-compose-app

One thing which is invariably true is that at this time, the device would be suffocating for some memory (which is usually the reason for GC to most likely get triggered).

As mentioned by almost all authors earlier, this issue surfaces when Android tries to run GC while the app is in background. In most of the cases where we observed it, user paused the app by locking their screen. This might also indicate memory leak somewhere in the application, or the device being too loaded already. So the only legitimate way to minimize it is:

• to ensure there are no memory leaks, and
• to reduce the memory footprint of the app in general.

Since I got here with my problem I will add this answer although it is not exactly relevant to the original question. When you are implementing an interface make sure you do not forget to add the type pointer on your member function declarations. Example:

type AnimalSounder interface {
    MakeNoise()
}

type Dog struct {
    Name string
    mean bool
    BarkStrength int
}

func (dog *Dog) MakeNoise() {
    //implementation
}

I forgot the *(dog Dog) part, I do not recommend it. Then you get into ugly trouble when calling MakeNoice on an AnimalSounder interface variable of type Dog.

You can use the ljust method on strings.

>>> name = 'John'
>>> name.ljust(15)
'John           '

Note that if the name is longer than 15 characters, ljust won't truncate it. If you want to end up with exactly 15 characters, you can slice the resulting string:

>>> name.ljust(15)[:15]

Rule of thumb: Use -a and -o inside square brackets, && and || outside.

It's important to understand the difference between shell syntax and the syntax of the [ command.

• && and || are shell operators. They are used to combine the results of two commands. Because they are shell syntax, they have special syntactical significance and cannot be used as arguments to commands.

• [ is not special syntax. It's actually a command with the name [, also known as test. Since [ is just a regular command, it uses -a and -o for its and and or operators. It can't use && and || because those are shell syntax that commands don't get to see.

But wait! Bash has a fancier test syntax in the form of [[ ]]. If you use double square brackets, you get access to things like regexes and wildcards. You can also use shell operators like &&, ||, <, and > freely inside the brackets because, unlike [, the double bracketed form is special shell syntax. Bash parses [[ itself so you can write things like [[ $foo == 5 && $bar == 6 ]].

Some additional info. for situations that'll need the win32gui solution posted by Mohsen Haddadi earlier in this thread:

As of python 361, win32gui & win32con are not part of the python std library. To use them, pywin32 package will need to be installed; now possible via pip.

More background info on pywin32 package is at: How to use the win32gui module with Python?.

Also, to apply discretion while closing a window so as to not inadvertently close any window in the foreground, the resolution could be extended along the lines of the following:

try     :

    import win32gui, win32con;

    frgrnd_wndw = win32gui.GetForegroundWindow();
    wndw_title  = win32gui.GetWindowText(frgrnd_wndw);
    if wndw_title.endswith("python.exe"):
        win32gui.ShowWindow(frgrnd_wndw, win32con.SW_HIDE);
    #endif
except  :
    pass

Your case is an extreme one, but here is a solution for others that fits a more common scenario of wanting to style fewer than 4 borders exactly the same.

border: 1px dashed red; border-width: 1px 1px 0 1px;

that is a little shorter, and maybe easier to read than

border-top: 1px dashed red;  border-right: 1px dashed red; border-left: 1px dashed red;

or

border-color: red; border-style: dashed; border-width: 1px 1px 0 1px;

To quote from the Python documentation:

As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter. If the script directory is not available (e.g. if the interpreter is invoked interactively or if the script is read from standard input), path[0] is the empty string, which directs Python to search modules in the current directory first. Notice that the script directory is inserted before the entries inserted as a result of PYTHONPATH.

sys.path[0] is what you are looking for.

Just use Python's standard string formatting methods:

>>> "{0:.2}".format(1.234232)
'1.2'
>>> "{0:.3}".format(1.234232)
'1.23'

If you are using a Python version under 2.6, use

>>> "%f" % 1.32423
'1.324230'
>>> "%.2f" % 1.32423
'1.32'
>>> "%d" % 1.32423
'1'

The general solution to interpreting a char as a string is string("HELLO"[1]).

Rich's solution also works, of course.

Please

1. locate the file [XAMPP Installation Directory]\php\php.ini (e.g. C:\xampp\php\php.ini)
2. open php.ini in Notepad or any Text editor
3. locate the line containing max_execution_time and
4. increase the value from 30 to some larger number (e.g. set: max_execution_time = 90)
5. then restart Apache web server from the XAMPP control panel

If there will still be the same error after that, try to increase the value for the max_execution_time further more.

Yes obviously.

That’s because a locally installed composer will give first preference to composer.lock file over composer.json.

If lock file is not available in vcs the composer will point to composer.json file to install latest dependencies or versions.

The file composer.lock maintains dependency in more depth i.e it points to the actual commit of the version of the package we include in our software, hence this is one of the most important files which handles the dependency more finely.

Try one of these solutions

1. In vscode settings.json file add this entry "prettier.singleQuote": true
2. In vscode if you have .editorconfig file, add this line under the root [*] symbol quote_type = single
3. In vscode if you have .prettierrc file, add this line

{
    "singleQuote": true,
    "vetur.format.defaultFormatterOptions": {
        "prettier": {
            "singleQuote": true
        }
    }
}

Lots of good answers but strange that no one has mentioned using a lambda function.
So if you have no arguments, things become pretty trivial:

def method1():
    return 'hello world'

def method2(methodToRun):
    result = methodToRun()
    return result

method2(method1)

But say you have one (or more) arguments in method1:

def method1(param):
    return 'hello ' + str(param)

def method2(methodToRun):
    result = methodToRun()
    return result

Then you can simply invoke method2 as method2(lambda: method1('world')).

method2(lambda: method1('world'))
>>> hello world
method2(lambda: method1('reader'))
>>> hello reader

I find this much cleaner than the other answers mentioned here.

With Jenkins Pipeline its possible to checkout multiple git repos and after building it using gradle

node {   
def gradleHome

stage('Prepare/Checkout') { // for display purposes
    git branch: 'develop', url: 'https://github.com/WtfJoke/Any.git'

    dir('a-child-repo') {
       git branch: 'develop', url: 'https://github.com/WtfJoke/AnyChild.git'
    }

    env.JAVA_HOME="${tool 'JDK8'}"
    env.PATH="${env.JAVA_HOME}/bin:${env.PATH}" // set java home in jdk environment
    gradleHome = tool '3.4.1' 
}

stage('Build') {
  // Run the gradle build
  if (isUnix()) {
     sh "'${gradleHome}/bin/gradle' clean build"
  } else {
     bat(/"${gradleHome}\bin\gradle" clean build/)
  }
}
}

You might want to consider using git submodules instead of a custom pipeline like this.

if you want to rotate inline elements, you should set the inline element to inline-block first.

i {
  display: inline-block;
}

i:hover {
  animation: rotate-btn .5s linear 3;
  -webkit-animation: rotate-btn .5s linear 3;
}

@keyframes rotate-btn {
  0% {
    transform: rotate(0);
  }
  100% {
    transform: rotate(-360deg);
  }
}

Here is how to create the desired outcome:

library(reshape2); library(tidyverse)
melt(outer(1:4, 1:4), varnames = c("X1", "X2")) %>%
ggplot() + 
  geom_tile(aes(X1, X2, fill = value)) + 
  scale_fill_continuous(guide = guide_legend()) +
  theme(legend.position="bottom",
        legend.spacing.x = unit(0, 'cm'))+
  guides(fill = guide_legend(label.position = "bottom"))

^{Created on 2019-12-07 by the reprex package (v0.3.0)}

Edit: no need for these imperfect options anymore, but I'm leaving them here for reference.

Two imperfect options that don't give you exactly what you were asking for, but pretty close (will at least put the colours together).

library(reshape2); library(tidyverse)
df <- melt(outer(1:4, 1:4), varnames = c("X1", "X2"))
p1 <- ggplot(df, aes(X1, X2)) + geom_tile(aes(fill = value))
p1 + scale_fill_continuous(guide = guide_legend()) +
 theme(legend.position="bottom", legend.direction="vertical")

p1 + scale_fill_continuous(guide = "colorbar") + theme(legend.position="bottom")

^{Created on 2019-02-28 by the reprex package (v0.2.1)}

another alternative, just in case you want to have a shell script which creates the database if it does not exist and otherwise just keeps it as it is:

psql -U postgres -tc "SELECT 1 FROM pg_database WHERE datname = 'my_db'" | grep -q 1 || psql -U postgres -c "CREATE DATABASE my_db"

I found this to be helpful in devops provisioning scripts, which you might want to run multiple times over the same instance.

For those of you who would like an explanation:

-c = run command in database session, command is given in string
-t = skip header and footer
-q = silent mode for grep 
|| = logical OR, if grep fails to find match run the subsequent command

If you are trying to use XAMPP with Windows and want to use an .htaccess file on a live server and also develop on a XAMPP development machine the following works great!

1) After a fresh install of XAMPP make sure that Apache is installed as a service.

• This is done by opening up the XAMPP Control Panel and clicking on the little red "X" to the left of the Apache module.
• It will then ask you if you want to install Apache as a service.
• Then it should turn to a green check mark.

2) When Apache is installed as a service add a new environment variable as a flag.

• First stop the Apache service from the XAMPP Control Panel.
• Next open a command prompt. (You know the little black window the simulates DOS)
• Type "C:\Program Files (x86)\xampp\apache\bin\httpd.exe" -D "DEV" -k config.
• This will append a new DEV flag to the environment variables that you can use later.

3) Start Apache

• Open back up the XAMPP Control Panel and start the Apache service.

4) Create your .htaccess file with the following information...

<IfDefine DEV>
  AuthType Basic
  AuthName "Authorized access only!"
  AuthUserFile "/sandbox/web/scripts/.htpasswd"
  require valid-user
</IfDefine>

<IfDefine !DEV>
  AuthType Basic
  AuthName "Authorized access only!"
  AuthUserFile "/home/arvo/public_html/scripts/.htpasswd"
  require valid-user
</IfDefine>

To explain the above script here are a few notes...

• My AuthUserFile is based on my setup and personal preferences.
• I have a local test dev box that has my webpage located at c:\sandbox\web\. Inside that folder I have a folder called scripts that contains the password file .htpasswd.
• The first entry IfDefine DEV is used for that instance. If DEV is set (which is what we did above, only on the dev machine of coarse) then it will use that entry.
• And in turn if using the live server IfDefine !DEV will be used.

5) Create your password file (in this case named .htpasswd) with the following information...

user:$apr1$EPuSBcwO$/KtqDUttQMNUa5lGXSOzk.

A few things to note...

• Your password file can be any name you want.
• You should use .htpasswd for security.
• A great password generator found @ http://www.htaccesstools.com/htpasswd-generator/
• A great explanation and reason why you should use that name for your file is located @ http://www.htaccesstools.com/articles/htpasswd/
• MAKE SURE YOU PUT THE PASSWORD FILE IN THE CORRECT LOCATION!!! (See step 4 AuthUserFile area)

Use a labeled break as an alternative to goto.

SELECT * FROM `table_name` 
ORDER BY `table_name`.`column_name` DESC

There is a useful undocumented method in the ZipArchive class: addGlob();

$zipFile = "./testZip.zip";
$zipArchive = new ZipArchive();

if ($zipArchive->open($zipFile, (ZipArchive::CREATE | ZipArchive::OVERWRITE)) !== true)
    die("Failed to create archive\n");

$zipArchive->addGlob("./*.txt");
if ($zipArchive->status != ZIPARCHIVE::ER_OK)
    echo "Failed to write files to zip\n";

$zipArchive->close();

Now documented at: www.php.net/manual/en/ziparchive.addglob.php

window.location is an object, not a string so you need to use window.location.href to get the actual string url

if (window.location.href.indexOf("?added-to-cart=555") >= 0) {
    alert("found it");
}

I know this is old, but here is a one liner solution:

const hourDiff = start.diff(end, "hours");

Where start and end are moment objects.

Enjoy!

(For future reference.)

Quite possibly the fastest way to do this would be to use memory mapped files (so primarily copying memory, and the OS handling the file reads/writes via its paging/memory management).

Memory Mapped files are supported in managed code in .NET 4.0.

But as noted, you need to profile, and expect to switch to native code for maximum performance.

You basically need to make a HTTP request to the service, and then parse the body of the response. I like to use httplib2 for it:

import httplib2 as http
import json

try:
    from urlparse import urlparse
except ImportError:
    from urllib.parse import urlparse

headers = {
    'Accept': 'application/json',
    'Content-Type': 'application/json; charset=UTF-8'
}

uri = 'http://yourservice.com'
path = '/path/to/resource/'

target = urlparse(uri+path)
method = 'GET'
body = ''

h = http.Http()

# If you need authentication some example:
if auth:
    h.add_credentials(auth.user, auth.password)

response, content = h.request(
        target.geturl(),
        method,
        body,
        headers)

# assume that content is a json reply
# parse content with the json module
data = json.loads(content)

The typical way to send binary in json is to base64 encode it.

Java provides different ways to Base64 encode and decode a byte[]. One of these is DatatypeConverter.

Very simply

byte[] originalBytes = new byte[] { 1, 2, 3, 4, 5};
String base64Encoded = DatatypeConverter.printBase64Binary(originalBytes);
byte[] base64Decoded = DatatypeConverter.parseBase64Binary(base64Encoded);

You'll have to make this conversion depending on the json parser/generator library you use.

According to the fine manual, createConnection() can be used to connect to multiple databases.

However, you need to create separate models for each connection/database:

var conn      = mongoose.createConnection('mongodb://localhost/testA');
var conn2     = mongoose.createConnection('mongodb://localhost/testB');

// stored in 'testA' database
var ModelA    = conn.model('Model', new mongoose.Schema({
  title : { type : String, default : 'model in testA database' }
}));

// stored in 'testB' database
var ModelB    = conn2.model('Model', new mongoose.Schema({
  title : { type : String, default : 'model in testB database' }
}));

I'm pretty sure that you can share the schema between them, but you have to check to make sure.

or... you can just put some style like this.

.panel-title a.collapsed {
     background: url(../img/arrow_right.png) center right no-repeat;
}
.panel-title a {
     background: url(../img/arrow_down.png) center right no-repeat;
}

SASS has a built-in rgba() function to evaluate values.

rgba($color, $alpha)

E.g.

rgba(#00aaff, 0.5) => rgba(0, 170, 255, 0.5)

An example using your own variables:

$my-color: #00aaff;
$my-opacity: 0.5;

.my-element {
  color: rgba($my-color, $my-opacity);
}

Outputs:

.my-element {
  color: rgba(0, 170, 255, 0.5);
}

Dan, it's just you're accessing the protected field instead of properties.

See for example this line in your Main(...):

myClub.distance = Console.ReadLine();

myClub.distance is the protected field, while you wanted to set the property mydistance.

I'm just giving you some hint, I'm not going to correct your code, since this is homework! ;)

Since Spark 1.5 you can use a number of date processing functions:

• pyspark.sql.functions.year
• pyspark.sql.functions.month
• pyspark.sql.functions.dayofmonth
• pyspark.sql.functions.dayofweek()
• pyspark.sql.functions.dayofyear
• pyspark.sql.functions.weekofyear()

import datetime
from pyspark.sql.functions import year, month, dayofmonth

elevDF = sc.parallelize([
    (datetime.datetime(1984, 1, 1, 0, 0), 1, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 2, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 3, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 4, 638.55),
    (datetime.datetime(1984, 1, 1, 0, 0), 5, 638.55)
]).toDF(["date", "hour", "value"])

elevDF.select(
    year("date").alias('year'), 
    month("date").alias('month'), 
    dayofmonth("date").alias('day')
).show()
# +----+-----+---+
# |year|month|day|
# +----+-----+---+
# |1984|    1|  1|
# |1984|    1|  1|
# |1984|    1|  1|
# |1984|    1|  1|
# |1984|    1|  1|
# +----+-----+---+

You can use simple map as with any other RDD:

elevDF = sqlContext.createDataFrame(sc.parallelize([
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=1, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=2, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=3, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=4, value=638.55),
        Row(date=datetime.datetime(1984, 1, 1, 0, 0), hour=5, value=638.55)]))

(elevDF
 .map(lambda (date, hour, value): (date.year, date.month, date.day))
 .collect())

and the result is:

[(1984, 1, 1), (1984, 1, 1), (1984, 1, 1), (1984, 1, 1), (1984, 1, 1)]

Btw: datetime.datetime stores an hour anyway so keeping it separately seems to be a waste of memory.

Guys this is how it worked for me:

1. Open terminal and go to user [See attached image]
2. Open .ssh folder and make sure it doesn't have any file like id_rsa or id_rsa.pub otherwise sometimes it wont properly rewrite files
3. git --version [Check for git installation and version]
4. git config --global user.email "your email id"
5. git config --global user.name "your name"
6. git config --list [make sure you have set your name & email]
7. cd ~/.ssh
8. ssh-keygen, it prompts for saving file, allow it
9. cat ~/.ssh/id_rsa.pub [Access your public key & copy the key to gerrit settings]

Note: You should not be using the sudo command with Git. If you have a very good reason you must use sudo, then ensure you are using it with every command (it's probably just better to use su to get a shell as root at that point). If you generate SSH keys without sudo and then try to use a command like sudo git push, you won't be using the same keys that you generated

To edit text in the file non-interactively, you need in-place text editor such as vim.

Here is simple example how to use it from the command line:

vim -esnc '%s/foo/bar/g|:wq' file.txt

This is equivalent to @slim answer of ex editor which is basically the same thing.

Here are few ex practical examples.

Replacing text foo with bar in the file:

ex -s +%s/foo/bar/ge -cwq file.txt

Removing trailing whitespaces for multiple files:

ex +'bufdo!%s/\s\+$//e' -cxa *.txt

Troubleshooting (when terminal is stuck):

• Add -V1 param to show verbose messages.
• Force quit by: -cwq!.

you should try using os.walk

yourpath = 'path'

import os
for root, dirs, files in os.walk(yourpath, topdown=False):
    for name in files:
        print(os.path.join(root, name))
        stuff
    for name in dirs:
        print(os.path.join(root, name))
        stuff

This is easy.

tell .gitignore to ignore everything except .gitignore and the folders you want to keep. Put .gitignore into folders that you want to keep in the repo.

Contents of the top-most .gitignore:

# ignore everything except .gitignore and folders that I care about:
*
!images*
!.gitignore

In the nested images folder this is your .gitignore:

# ignore everything except .gitignore
*
!.gitignore

Note, you must spell out in the .gitignore the names of the folders you don't want to be ignored in the folder where that .gitignore is located. Otherwise they are, obviously, ignored.

Your folders in the repo will, obviously, NOT be empty, as each one will have .gitignore in it, but that part can be ignored, right. :)

In ES2017 you can use Object.values():

Object.values(data)

At the time of writing support is limited (FireFox and Chrome).All major browsers except IE support this now.

In ES2015 you can use this:

Object.keys(data).map(k => data[k])

Another solution:

enum Suit: String {
    case spades = "?"
    case hearts = "?"
    case diamonds = "?"
    case clubs = "?"

    static var count: Int {
        return 4   
    }

    init(index: Int) {
        switch index {
            case 0: self = .spades
            case 1: self = .hearts
            case 2: self = .diamonds
            default: self = .clubs
        }
    }
}

for i in 0..<Suit.count {
    print(Suit(index: i).rawValue)
}

In addition to the top-answer, CSV files, for example, are reported as text/plain under macOS but as application/vnd.ms-excel under Windows. So I use this:

<input type="file" accept="text/plain, .csv, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, application/vnd.ms-excel" />

You can also use Requestify, a really cool and very simple HTTP client I wrote for nodeJS + it supports caching.

Just do the following for executing a POST request:

var requestify = require('requestify');

requestify.post('http://example.com', {
    hello: 'world'
})
.then(function(response) {
    // Get the response body (JSON parsed or jQuery object for XMLs)
    response.getBody();
});

I have a very specific use case for re-ordering column names in pandas. Sometimes I am creating a new column in a dataframe that is based on an existing column.

If your content type is already UTF8 , then it is likely the data is already arriving in the wrong encoding. If you are getting the data from a database, make sure the database connection uses UTF-8.

If this is data from a file, make sure the file is encoded correctly as UTF-8. You can usually set this in the "Save as..." Dialog of the editor of your choice.

If the data is already broken when you view it in the source file, chances are that it used to be a UTF-8 file but was saved in the wrong encoding somewhere along the way.

int hr=Time.valueOf(LocalTime.now()).getHours();
int minutes=Time.valueOf(LocalTime.now()).getMinutes();

These functions will return int values in hours and minutes.

this works for me:

git add my_file.txt
git diff --cached my_file.txt
git reset my_file.txt

Last step is optional, it will leave the file in the previous state (untracked)

useful if you are creating a patch too:

  git diff --cached my_file.txt > my_file-patch.patch

Unexpected (

Opening parentheses typically follow language constructs such as if/foreach/for/array/list or start an arithmetic expression. They're syntactically incorrect after "strings", a previous (), a lone $, and in some typical declaration contexts.

1. Function declaration parameters

   A rarer occurrence for this error is trying to use expressions as default function parameters. This is not supported, even in PHP7:

   function header_fallback($value, $expires = time() + 90000) {
   

   Parameters in a function declaration can only be literal values or constant expressions. Unlike for function invocations, where you can freely use whatever(1+something()*2), etc.

2. Class property defaults

   Same thing for class member declarations, where only literal/constant values are allowed, not expressions:

   class xyz {                   ?
       var $default = get_config("xyz_default");
   

   Put such things in the constructor. See also Why don't PHP attributes allow functions?

   Again note that PHP 7 only allows var $xy = 1 + 2 +3; constant expressions there.

3. JavaScript syntax in PHP

   Using JavaScript or jQuery syntax won't work in PHP for obvious reasons:

   <?php      ?
       print $(document).text();
   

   When this happens, it usually indicates an unterminated preceding string; and literal <script> sections leaking into PHP code context.

4. isset(()), empty, key, next, current

   Both isset() and empty() are language built-ins, not functions. They need to access a variable directly. If you inadvertently add a pair of parentheses too much, then you'd create an expression however:

             ?
   if (isset(($_GET["id"]))) {
   

   The same applies to any language construct that requires implicit variable name access. These built-ins are part of the language grammar, therefore don't permit decorative extra parentheses.

   User-level functions that require a variable reference -but get an expression result passed- lead to runtime errors instead.

Unexpected )

1. Absent function parameter

   You cannot have stray commas last in a function call. PHP expects a value there and thusly complains about an early closing ) parenthesis.

                 ?
   callfunc(1, 2, );
   

   A trailing comma is only allowed in array() or list() constructs.

2. Unfinished expressions

   If you forget something in an arithmetic expression, then the parser gives up. Because how should it possibly interpret that:

                  ?
   $var = 2 * (1 + );
   

   And if you forgot the closing ) even, then you'd get a complaint about the unexpected semicolon instead.

3. Foreach as constant

   For forgotten variable $ prefixes in control statements you will see:

                      ?    ?
   foreach ($array as wrong) {
   

   PHP here sometimes tells you it expected a :: instead. Because a class::$variable could have satisfied the expected $variable expression..

Unexpected {

Curly braces { and } enclose code blocks. And syntax errors about them usually indicate some incorrect nesting.

1. Unmatched subexpressions in an if

   Most commonly unbalanced ( and ) are the cause if the parser complains about the opening curly { appearing too early. A simple example:

                                 ?
   if (($x == $y) && (2 == true) {
   

   Count your parentheses or use an IDE which helps with that. Also don't write code without any spaces. Readability counts.

2. { and } in expression context

   You can't use curly braces in expressions. If you confuse parentheses and curlys, it won't comply to the language grammar:

              ?
   $var = 5 * {7 + $x};
   

   There are a few exceptions for identifier construction, such as local scope variable ${references}.

3. Variable variables or curly var expressions

   This is pretty rare. But you might also get { and } parser complaints for complex variable expressions:

                         ?
   print "Hello {$world[2{]} !";
   

   Though there's a higher likelihood for an unexpected } in such contexts.

Unexpected }

When getting an "unexpected }" error, you've mostly closed a code block too early.

1. Last statement in a code block

   It can happen for any unterminated expression.

   And if the last line in a function/code block lacks a trailing ; semicolon:

   function whatever() {
       doStuff()
   }            ?
   

   Here the parser can't tell if you perhaps still wanted to add + 25; to the function result or something else.

2. Invalid block nesting / Forgotten {

   You'll sometimes see this parser error when a code block was } closed too early, or you forgot an opening { even:

   function doStuff() {
       if (true)    ?
           print "yes";
       }
   }   ?
   

   In above snippet the if didn't have an opening { curly brace. Thus the closing } one below became redundant. And therefore the next closing }, which was intended for the function, was not associable to the original opening { curly brace.

   Such errors are even harder to find without proper code indentation. Use an IDE and bracket matching.

Unexpected {, expecting (

Language constructs which require a condition/declaration header and a code block will trigger this error.

1. Parameter lists

   For example misdeclared functions without parameter list are not permitted:

                    ?
   function whatever {
   }
   

2. Control statement conditions

   And you can't likewise have an if without condition.

     ?
   if {
   }
   

   Which doesn't make sense, obviously. The same thing for the usual suspects, for/foreach, while/do, etc.

   If you've got this particular error, you definitely should look up some manual examples.

Well, I have a similar project where users upload files onto the server. Under my point of view, option a) is the best solution due to it's more flexible. What you must do is storing images in a protected folder classified by subdirectories. The main directory must be set up by the administrator as the content must no run scripts (very important) and (read, write) protected for not be accesible in http request.

I hope this helps you.

var moment = require("moment");
var momentDurationFormatSetup = require("moment-duration-format")

var now  = "2015-07-16T16:33:39.113Z";
var then = "2015-06-16T22:33:39.113Z";

var ms = moment(now,"YYYY-MM-DD'T'HH:mm:ss:SSSZ").diff(moment(then,"YYYY-MM-DD'T'HH:mm:ss:SSSZ"));
var d = moment.duration(ms);
var s = d.format("dd:hh:mm:ss");
console.log(s);

I experienced the same problem when I copied a text that has an apostrophe from a Word document to my HTML code.

To resolve the issue, all I did was deleted the particular word in my HTML and typed it directly, including the apostrophe. This action nullified the original copy and paste acton and displayed the newly typed apostrophe correctly

my start.sh file:

#/bin/bash

nohup forever -c php artisan your:command >>storage/logs/yourcommand.log 2>&1 &

There is one important thing only. FIRST COMMAND MUST BE "nohup", second command must be "forever" and "-c" parameter is forever's param, "2>&1 &" area is for "nohup". After running this line then you can logout from your terminal, relogin and run "forever restartall" voilaa... You can restart and you can be sure that if script halts then forever will restart it.

UPDATE only changes the values you specify:

UPDATE table SET cell='new_value' WHERE whatever='somevalue'

You can use a function like strtol() which will convert a character array to a long.

It has a parameter which is a way to detect the first character that didn't convert properly. If this is anything other than the end of the string, then you have a problem.

See the following program for an example:

#include <stdio.h>
#include <stdlib.h>

int main( int argc, char *argv[]) {
    int i;
    long val;
    char *next;

    // Process each argument given.

    for (i = 1; i < argc; i++) {
        // Get value with failure detection.

        val = strtol (argv[i], &next, 10);

        // Check for empty string and characters left after conversion.

        if ((next == argv[i]) || (*next != '\0')) {
            printf ("'%s' is not valid\n", argv[i]);
        } else {
            printf ("'%s' gives %ld\n", argv[i], val);
        }
    }

    return 0;
}

Running this, you can see it in operation:

pax> testprog hello "" 42 12.2 77x

'hello' is not valid
'' is not valid
'42' gives 42
'12.2' is not valid
'77x' is not valid

Without using eval('function()') you could to create a new function using new Function(strName). The below code was tested using FF, Chrome, IE.

<html>
<body>
<button onclick="test()">Try it</button>
</body>
</html>
<script type="text/javascript">

  function test() {
    try {    
        var fnName = "myFunction()";
        var fn = new Function(fnName);
        fn();
      } catch (err) {
        console.log("error:"+err.message);
      }
  }

  function myFunction() {
    console.log('Executing myFunction()');
  }

</script>

I needed something like that and the solution I gave with the help of jquery is this:

<textarea class="textlimited" data-textcounterid="counter1" maxlength="30">text</textarea>
<span class='textcounter' id="counter1"></span>

With this script:

// the selector below will catch the keyup events of elements decorated with class textlimited and have a maxlength
$('.textlimited[maxlength]').keyup(function(){
     //get the fields limit
    var maxLength = $(this).attr("maxlength");

    // check if the limit is passed
    if(this.value.length > maxLength){
        return false;
    }

    // find the counter element by the id specified in the source input element
    var counterElement = $(".textcounter#" + $(this).data("textcounterid"));
    // update counter 's text
    counterElement.html((maxLength - this.value.length) + " chars left");
});

In simpler words, you can understand Bootstrap as a front-end web framework that was created by Twitter for faster creation of device responsive web applications. Bootstrap can also be understood mostly as a collection of CSS classes that are defined in it which can simply be used directly. It makes use of CSS, javascript, jQuery etc. in the background to create the style, effects, and actions for Bootstrap elements.

You might know that we use CSS for styling webpage elements and create classes and assign classes to webpage elements to apply the style to them. Bootstrap here makes the designing simpler since we only have to include Bootstrap files and mention Bootstrap's predefined class names for our webpage elements and they will be styled automatically through Bootstrap. Through this, we get rid of writing our own CSS classes to style webpage elements. Most importantly Bootstrap is designed in such a way that makes your website device responsive and that is the main purpose of it. Other alternates for Bootstrap could be - Foundation, Materialize etc. frameworks.

Bootstrap makes you free from writing lots of CSS code and it also saves your time that you spend on designing the web pages.

TL;DR

Transient objects are always different; a new instance is provided to every controller and every service.

Scoped objects are the same within a request, but different across different requests.

Singleton objects are the same for every object and every request.

For more clarification, this example from .NET documentation shows the difference:

To demonstrate the difference between these lifetime and registration options, consider a simple interface that represents one or more tasks as an operation with a unique identifier, OperationId. Depending on how we configure the lifetime for this service, the container will provide either the same or different instances of the service to the requesting class. To make it clear which lifetime is being requested, we will create one type per lifetime option:

using System;

namespace DependencyInjectionSample.Interfaces
{
    public interface IOperation
    {
        Guid OperationId { get; }
    }

    public interface IOperationTransient : IOperation
    {
    }

    public interface IOperationScoped : IOperation
    {
    }

    public interface IOperationSingleton : IOperation
    {
    }

    public interface IOperationSingletonInstance : IOperation
    {
    }
}

We implement these interfaces using a single class, Operation, that accepts a GUID in its constructor, or uses a new GUID if none is provided:

using System;
using DependencyInjectionSample.Interfaces;
namespace DependencyInjectionSample.Classes
{
    public class Operation : IOperationTransient, IOperationScoped, IOperationSingleton, IOperationSingletonInstance
    {
        Guid _guid;
        public Operation() : this(Guid.NewGuid())
        {

        }

        public Operation(Guid guid)
        {
            _guid = guid;
        }

        public Guid OperationId => _guid;
    }
}

Next, in ConfigureServices, each type is added to the container according to its named lifetime:

services.AddTransient<IOperationTransient, Operation>();
services.AddScoped<IOperationScoped, Operation>();
services.AddSingleton<IOperationSingleton, Operation>();
services.AddSingleton<IOperationSingletonInstance>(new Operation(Guid.Empty));
services.AddTransient<OperationService, OperationService>();

Note that the IOperationSingletonInstance service is using a specific instance with a known ID of Guid.Empty, so it will be clear when this type is in use. We have also registered an OperationService that depends on each of the other Operation types, so that it will be clear within a request whether this service is getting the same instance as the controller, or a new one, for each operation type. All this service does is expose its dependencies as properties, so they can be displayed in the view.

using DependencyInjectionSample.Interfaces;

namespace DependencyInjectionSample.Services
{
    public class OperationService
    {
        public IOperationTransient TransientOperation { get; }
        public IOperationScoped ScopedOperation { get; }
        public IOperationSingleton SingletonOperation { get; }
        public IOperationSingletonInstance SingletonInstanceOperation { get; }

        public OperationService(IOperationTransient transientOperation,
            IOperationScoped scopedOperation,
            IOperationSingleton singletonOperation,
            IOperationSingletonInstance instanceOperation)
        {
            TransientOperation = transientOperation;
            ScopedOperation = scopedOperation;
            SingletonOperation = singletonOperation;
            SingletonInstanceOperation = instanceOperation;
        }
    }
}

To demonstrate the object lifetimes within and between separate individual requests to the application, the sample includes an OperationsController that requests each kind of IOperation type as well as an OperationService. The Index action then displays all of the controller’s and service’s OperationId values.

using DependencyInjectionSample.Interfaces;
using DependencyInjectionSample.Services;
using Microsoft.AspNetCore.Mvc;

namespace DependencyInjectionSample.Controllers
{
    public class OperationsController : Controller
    {
        private readonly OperationService _operationService;
        private readonly IOperationTransient _transientOperation;
        private readonly IOperationScoped _scopedOperation;
        private readonly IOperationSingleton _singletonOperation;
        private readonly IOperationSingletonInstance _singletonInstanceOperation;

        public OperationsController(OperationService operationService,
            IOperationTransient transientOperation,
            IOperationScoped scopedOperation,
            IOperationSingleton singletonOperation,
            IOperationSingletonInstance singletonInstanceOperation)
        {
            _operationService = operationService;
            _transientOperation = transientOperation;
            _scopedOperation = scopedOperation;
            _singletonOperation = singletonOperation;
            _singletonInstanceOperation = singletonInstanceOperation;
        }

        public IActionResult Index()
        {
            // ViewBag contains controller-requested services
            ViewBag.Transient = _transientOperation;
            ViewBag.Scoped = _scopedOperation;
            ViewBag.Singleton = _singletonOperation;
            ViewBag.SingletonInstance = _singletonInstanceOperation;

            // Operation service has its own requested services
            ViewBag.Service = _operationService;
            return View();
        }
    }
}

Now two separate requests are made to this controller action:

Observe which of the OperationId values varies within a request, and between requests.

• Transient objects are always different; a new instance is provided to every controller and every service.

• Scoped objects are the same within a request, but different across different requests

• Singleton objects are the same for every object and every request (regardless of whether an instance is provided in ConfigureServices)

try this one:

The answer by ehynds will not work, because it caches the responses data. It should cache the jqXHR which is also a Promise. Here is the correct code:

var cache = {};

function getData( val ){

    // return either the cached value or an
    // jqXHR object (which contains a promise)
    return cache[ val ] || $.ajax('/foo/', {
        data: { value: val },
        dataType: 'json',
        success: function(data, textStatus, jqXHR){
            cache[ val ] = jqXHR;
        }
    });
}

getData('foo').then(function(resp){
    // do something with the response, which may
    // or may not have been retreived using an
    // XHR request.
});

The answer by Julian D. will work correct and is a better solution.

I solve my issue by using utf8_encode();

$str = "kamé";

echo utf8_encode($str);

Hope this help someone.

Add your new class "tableresp" with table-responisve class and then add below code in your js file

$(".tableresp").on('click', '.dropdown-toggle', function(event) {

    if ($('.dropdown-menu').length) {
        var elm = $('.dropdown-menu'),
            docHeight = $(document).height(),
            docWidth = $(document).width(),
            btn_offset = $(this).offset(),
            btn_width = $(this).outerWidth(),
            btn_height = $(this).outerHeight(),
            elm_width = elm.outerWidth(),
            elm_height = elm.outerHeight(),
            table_offset = $(".tableresp").offset(),
            table_width = $(".tableresp").width(),
            table_height = $(".tableresp").height(),

            tableoffright = table_width + table_offset.left,
            tableoffbottom = table_height + table_offset.top,
            rem_tablewidth = docWidth - tableoffright,
            rem_tableheight = docHeight - tableoffbottom,
            elm_offsetleft = btn_offset.left,
            elm_offsetright = btn_offset.left + btn_width,
            elm_offsettop = btn_offset.top + btn_height,
            btn_offsetbottom = elm_offsettop,

            left_edge = (elm_offsetleft - table_offset.left) < elm_width,
            top_edge = btn_offset.top < elm_height,
            right_edge = (table_width - elm_offsetleft) < elm_width,
            bottom_edge = (tableoffbottom - btn_offsetbottom) < elm_height;

        console.log(tableoffbottom);
        console.log(btn_offsetbottom);
        console.log(bottom_edge);
        console.log((tableoffbottom - btn_offsetbottom) + "|| " + elm_height);


        var table_offset_bottom = docHeight - (table_offset.top + table_height);

        var touchTableBottom = (btn_offset.top + btn_height + (elm_height * 2)) - table_offset.top;

        var bottomedge = touchTableBottom > table_offset_bottom;

        if (left_edge) {
            $(this).addClass('left-edge');
        } else {
            $('.dropdown-menu').removeClass('left-edge');
        }
        if (bottom_edge) {
            $(this).parent().addClass('dropup');
        } else {
            $(this).parent().removeClass('dropup');
        }

    }
});
var table_smallheight = $('.tableresp'),
    positioning = table_smallheight.parent();

if (table_smallheight.height() < 320) {
    positioning.addClass('positioning');
    $('.tableresp .dropdown,.tableresp .adropup').css('position', 'static');

} else {
    positioning.removeClass('positioning');
    $('.tableresp .dropdown,.tableresp .dropup').css('position', 'relative');

}

Pure JavaScript ES6 solution

• Catch every option with a querySelectorAll function and split the values string.
• Use Array#forEach to iterate over every element from the values array.
• Use Array#find to find the option matching given value.
• Set it's selected attribute to true.

Note: Array#from transforms an array-like object into an array and then you are able to use Array.prototype functions on it, like find or map.

var values = "Test,Prof,Off",_x000D_
    options = Array.from(document.querySelectorAll('#strings option'));_x000D_
_x000D_
values.split(',').forEach(function(v) {_x000D_
  options.find(c => c.value == v).selected = true;_x000D_
});

<select name='strings' id="strings" multiple style="width:100px;">_x000D_
    <option value="Test">Test</option>_x000D_
    <option value="Prof">Prof</option>_x000D_
    <option value="Live">Live</option>_x000D_
    <option value="Off">Off</option>_x000D_
    <option value="On">On</option>_x000D_
</select>

The answer to this question is, use nuget to obtain JSON.NET then use this inside your JsonResult method:

JsonConvert.SerializeObject(/* JSON OBJECT TO SEND TO VIEW */);

inside your view simple do this in javascript:

JSON.parse(/* Converted JSON object */)

If it is an ajax call:

var request = $.ajax({ url: "@Url.Action("SomeAjaxAction", "SomeController")", dataType: "json"});
request.done(function (data, result) { var safe = JSON.parse(data); var date = new Date(safe.date); });

Once JSON.parse has been called, you can put the JSON date into a new Date instance because JsonConvert creates a proper ISO time instance

If you will use Regex, it already has a predefined character class "\S" for any non-whitespace character.

!str.matches("\\S+")

tells you if this is a string of at least one character where all characters are non-whitespace

You can use regexp grep for finding + second grep for highlight

echo "some123_string_and_another" | grep -o -P '.{0,3}string.{0,4}' | grep string

23_string_and

Sun JDK (1.6) has a shorter list of supported warnings:

• deprecation Check for use of depreciated items.
• unchecked Give more detail for unchecked conversion warnings that are mandated by the Java Language Specification.
• serial Warn about missing serialVersionUID definitions on serializable classes.
• finally Warn about finally clauses that cannot complete normally.
• fallthrough Check switch blocks for fall-through cases and provide a warning message for any that are found.
• path Check for a nonexistent path in environment paths (such as classpath).

The latest available javac (1.6.0_13) for mac have the following supported warnings

• all
• cast
• deprecation
• divzero
• empty
• unchecked
• fallthrough
• path
• serial
• finally
• overrides

A technique I use is something like the following. Define a global variable that you can use for one or multiple try catch blocks depending on what you're trying to debug and use the following structure:

if(!GlobalTestingBool)
{
   try
   {
      SomeErrorProneMethod();
   }
   catch (...)
   {
      // ... Error handling ...
   }
}
else
{
   SomeErrorProneMethod();
}

I find this gives me a bit more flexibility in terms of testing because there are still some exceptions I don't want the IDE to break on.

Take a look at this example from The Linux Documentation Project:

3.6 Sample: stderr and stdout 2 file

This will place every output of a program to a file. This is suitable sometimes for cron entries, if you want a command to pass in absolute silence.

     rm -f $(find / -name core) &> /dev/null 

That said, you can use this simple redirection:

/path/to/command &>/dev/null

The .getTimezoneOffset() method should work. This will get the time between your time zone and GMT. You can then calculate to whatever you want.

if using react:

const html = ReactDOM.findDOMNode(document.getElementsByTagName('html')[0]).outerHTML;

Equals -

1- Override the GetHashCode method to allow a type to work correctly in a hash table.

2- Do not throw an exception in the implementation of an Equals method. Instead, return false for a null argument.

3-

  x.Equals(x) returns true.

  x.Equals(y) returns the same value as y.Equals(x).

  (x.Equals(y) && y.Equals(z)) returns true if and only if x.Equals(z) returns true.

Successive invocations of x.Equals(y) return the same value as long as the object referenced by x and y are not modified.

x.Equals(null) returns false.

4- For some kinds of objects, it is desirable to have Equals test for value equality instead of referential equality. Such implementations of Equals return true if the two objects have the same value, even if they are not the same instance.

For Example -

   Object obj1 = new Object();
   Object obj2 = new Object();
   Console.WriteLine(obj1.Equals(obj2));
   obj1 = obj2; 
   Console.WriteLine(obj1.Equals(obj2)); 

Output :-

False
True

while compareTo -

Compares the current instance with another object of the same type and returns an integer that indicates whether the current instance precedes, follows, or occurs in the same position in the sort order as the other object.

It returns -

Less than zero - This instance precedes obj in the sort order. Zero - This instance occurs in the same position in the sort order as obj. Greater than zero - This instance follows obj in the sort order.

It can throw ArgumentException if object is not the same type as instance.

For example you can visit here.

So I suggest better to use Equals in place of compareTo.

If you know the sessionID then you can use the following:

SELECT * FROM sys.dm_exec_requests WHERE session_id = 62

Or if you want to narrow it down:

SELECT command, percent_complete, start_time FROM sys.dm_exec_requests WHERE session_id = 62

I have a diary class and so i am not writing setting the values again and again

public Diary() {
    this.Like = defaultLike;
    this.Dislike = defaultDislike;
}

public Diary(string title, string diary): this()
{
    this.Title = title;
    this.DiaryText = diary;
}

public Diary(string title, string diary, string category): this(title, diary) {
    this.Category = category;
}

public Diary(int id, string title, string diary, string category)
    : this(title, diary, category)
{
    this.DiaryID = id;
}

Only load jQuery itself in the head, via CDN of course.

Why? In some scenarios you might include a partial template (e.g. ajax login form snippet) with embedded jQuery dependent code; if jQuery is loaded at page bottom, you get a "$ is not defined" error, nice.

There are ways to workaround this of course (such as not embedding any JS and appending to a load-at-bottom js bundle), but why lose the freedom of lazily loaded js, of being able to place jQuery dependent code anywhere you please? Javascript engine doesn't care where the code lives in the DOM so long as dependencies (like jQuery being loaded) are satisfied.

For your common/shared js files, yes, place them before </body>, but for the exceptions, where it really just makes sense application maintenance-wise to stick a jQuery dependent snippet or file reference right there at that point in the html, do so.

There is no performance hit loading jquery in the head; what browser on the planet does not already have jQuery CDN file in cache?

Much ado about nothing, stick jQuery in the head and let your js freedom reign.

According to the problem you can try this...

// looping between date range    
while (startDate <= endDate)
{
    //here will be your code block...

    startDate = startDate.AddDays(1);
}

thanks......

I know this is a little late, but if someone else comes across this looking, you can now use public_path(); in Laravel 4, it has been added to the helper.php file in the support folder see here.

This is ridiculous but I just have rebooted my machine (mac) and the problem was gone like it has never happened. I hate to sound like a support guy...

Use the wc utility with the print the byte counts (-c) option:

$ SO="stackoverflow"
$ echo -n "$SO" | wc -c
    13

You'll have to use the do not output the trailing newline (-n) option for echo. Otherwise, the newline character will also be counted.

In the run configuration you want to customize (just click on it) open the tab Arguments and add -Xmx2048min the VM arguments section. You might want to set the -Xms as well (small heap size).

You will want to use the a ternary operator which acts as a shortened IF/Else statement:

echo '<option value="'.$value.'" '.(($value=='United States')?'selected="selected"':"").'>'.$value.'</option>';

This workaround is dangerous and not recommended:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

It's not a good idea to disable SSL peer verification. Doing so might expose your requests to MITM attackers.

In fact, you just need an up-to-date CA root certificate bundle. Installing an updated one is as easy as:

1. Downloading up-to-date cacert.pem file from cURL website and

2. Setting a path to it in your php.ini file, e.g. on Windows:

   curl.cainfo=c:\php\cacert.pem

That's it!

Stay safe and secure.

There are probably less than 20 entries in your xml.

change the code to this

As others have said, there are patterns specific to functional programming. I think the issue of getting rid of design patterns is not so much a matter of switching to functional, but a matter of language features.

Take a look at how Scala does away with the "singleton pattern": you simply declare an object instead of a class. Another feature, pattern matching, helps avoiding the clunkiness of the visitor pattern. See the comparison here: Scala's Pattern Matching = Visitor Pattern on Steroids

And Scala, like F#, is a fusion of OO-functional. I don't know about F#, but it probably has these kind of features.

Closures are present in functional language, but they need not be restricted to them. They help with the delegator pattern.

One more observation. This piece of code implements a pattern: it's such a classic and it's so elemental that we don't usually think of it as a "pattern", but it sure is:

for(int i = 0; i < myList.size(); i++) { doWhatever(myList.get(i)); }

Imperative languages like Java and C# have adopted what is essentially a functional construct to deal with this: "foreach".

You can always use an attribute selector. The selector itself would look something like:

a[data-item-id=stand-out]

This can be done by building a javascript object to match your mvc model. The names of the javascript properties have to match exactly to the mvc model or else the autobind won't happen on the post. Once you have your model on the server side you can then manipulate it and store the data to the database.

I am achieving this either by a double click event on a grid row or click event on a button of some sort.

@model TestProject.Models.TestModel

<script>

function testButton_Click(){
  var javaModel ={
  ModelId: '@Model.TestId',
  CreatedDate: '@Model.CreatedDate.ToShortDateString()',
  TestDescription: '@Model.TestDescription',
  //Here I am using a Kendo editor and I want to bind the text value to my javascript
  //object. This may be different for you depending on what controls you use.
  TestStatus: ($('#StatusTextBox'))[0].value, 
  TestType: '@Model.TestType'
  }

  //Now I did for some reason have some trouble passing the ENUM id of a Kendo ComboBox 
    //selected value. This puzzled me due to the conversion to Json object in the Ajax call. 
  //By parsing the Type to an int this worked.

  javaModel.TestType = parseInt(javaModel.TestType);

  $.ajax({
      //This is where you want to post to.
      url:'@Url.Action("TestModelUpdate","TestController")', 
      async:true,
      type:"POST",
      contentType: 'application/json',
      dataType:"json",
      data: JSON.stringify(javaModel)
  });
}
</script>


//This is your controller action on the server, and it will autobind your values 
//to the newTestModel on post.

[HttpPost]
public ActionResult TestModelUpdate(TestModel newTestModel)
{
 TestModel.UpdateTestModel(newTestModel);
 return //do some return action;
}

contents = open(filename)

This gives you generator so you must save somewhere the values though, or

contents = [line for line in open(filename)]

This does the saving to list explicit close is not then possible (at least with my knowledge of Python).

Make use of jquery toggle function which do the task for you

.toggle() - Display or hide the matched elements.

$('#myelement').click(function(){
      $('#another-element').toggle('slow');
  });

Code below copied from -> Here

First off, you must save your work book as a macro enabled work book. So it would need to be xlsm not an xlsx. Otherwise, excel will disable the macro's due to not being macro enabled.

Set your vbscript (C:\excel\tester.vbs). The example sub "test()" must be located in your modules on the excel document.

dim eApp
set eApp = GetObject("C:\excel\tester.xlsm")
eApp.Application.Run "tester.xlsm!test"
set eApp = nothing

Then set your Schedule, give it a name, and a username/password for offline access.

Then you have to set your actions and triggers.

Set your schedule(trigger)

Action, set your vbscript to open with Cscript.exe so that it will be executed in the background and not get hung up by any error handling that vbcript has enabled.

Try:

num3 = 100000000000LL;

And BTW, in C++ this is a compiler extension, the standard does not define long long, thats part of C99.

string replace() function perfectly solves this problem:

string.replace(s, old, new[, maxreplace])

Return a copy of string s with all occurrences of substring old replaced by new. If the optional argument maxreplace is given, the first maxreplace occurrences are replaced.

>>> u'longlongTESTstringTEST'.replace('TEST', '?', 1)
u'longlong?stringTEST'

For me the problem was caused by a gradle.properties file in the list of Gradle scripts. It showed as gradle.properties (global) and refered to a file in C:\users\.gradle\gradle.properties. I right-clicked on it and selected delete from the menu to delete it. It deleted the file from the hard disk and my project now builds and runs. I guess that the global file was overwriting something that was used to locate the package android.support

You are mixing code that was compiled with /MD (use DLL version of CRT) with code that was compiled with /MT (use static CRT library). That cannot work, all source code files must be compiled with the same setting. Given that you use libraries that were pre-compiled with /MD, almost always the correct setting, you must compile your own code with this setting as well.

Project + Properties, C/C++, Code Generation, Runtime Library.

Beware that these libraries were probably compiled with an earlier version of the CRT, msvcr100.dll is quite new. Not sure if that will cause trouble, you may have to prevent the linker from generating a manifest. You must also make sure to deploy the DLLs you need to the target machine, including msvcr100.dll

If I understand correctly, you should be able to do what you want by dropping the foreign key constraint, adding a new one (which will cascade), doing your stuff, and recreating the restricting foreign key constraint.

For example:

testing=# create table a (id integer primary key);
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "a_pkey" for table "a"
CREATE TABLE
testing=# create table b (id integer references a);
CREATE TABLE

-- put some data in the table
testing=# insert into a values(1);
INSERT 0 1
testing=# insert into a values(2);
INSERT 0 1
testing=# insert into b values(2);
INSERT 0 1
testing=# insert into b values(1);
INSERT 0 1

-- restricting works
testing=# delete from a where id=1;
ERROR:  update or delete on table "a" violates foreign key constraint "b_id_fkey" on table "b"
DETAIL:  Key (id)=(1) is still referenced from table "b".

-- find the name of the constraint
testing=# \d b;
       Table "public.b"
 Column |  Type   | Modifiers 
--------+---------+-----------
 id     | integer | 
Foreign-key constraints:
    "b_id_fkey" FOREIGN KEY (id) REFERENCES a(id)

-- drop the constraint
testing=# alter table b drop constraint b_a_id_fkey;
ALTER TABLE

-- create a cascading one
testing=# alter table b add FOREIGN KEY (id) references a(id) on delete cascade; 
ALTER TABLE

testing=# delete from a where id=1;
DELETE 1
testing=# select * from a;
 id 
----
  2
(1 row)

testing=# select * from b;
 id 
----
  2
(1 row)

-- it works, do your stuff.
-- [stuff]

-- recreate the previous state
testing=# \d b;
       Table "public.b"
 Column |  Type   | Modifiers 
--------+---------+-----------
 id     | integer | 
Foreign-key constraints:
    "b_id_fkey" FOREIGN KEY (id) REFERENCES a(id) ON DELETE CASCADE

testing=# alter table b drop constraint b_id_fkey;
ALTER TABLE
testing=# alter table b add FOREIGN KEY (id) references a(id) on delete restrict; 
ALTER TABLE

Of course, you should abstract stuff like that into a procedure, for the sake of your mental health.

This works for me:

@Transactional
public void remove(Integer groupId) {
    Group group = groupRepository.findOne(groupId);
    group.getUsers().removeAll(group.getUsers());

    // Other business logic

    groupRepository.delete(group);
}

Also, mark the method @Transactional (org.springframework.transaction.annotation.Transactional), this will do whole process in one session, saves some time.

insert into TABLENAMEA (A,B,C,D) 
select A::integer,B,C,D from TABLENAMEB

np.array() is even more powerful than what unutbu said above. You also could use it to convert a list of np arrays to a higher dimention array, the following is a simple example:

aArray=np.array([1,1,1])

bArray=np.array([2,2,2])

aList=[aArray, bArray]

xArray=np.array(aList)

xArray's shape is (2,3), it's a standard np array. This operation avoids a loop programming.

I've encountered this issue today and could not use refactor to BigDecimal, because the project is really huge. However I found solution using

Float result = new Float(5623.23)
Double doubleResult = new FloatingDecimal(result.floatValue()).doubleValue()

And this works.

Note that calling result.doubleValue() returns 5623.22998046875

But calling doubleResult.doubleValue() returns correctly 5623.23

But I am not entirely sure if its a correct solution.

Basically I was trying to get my code to have a middle section on a 'row' to auto-adjust to the content on both sides (in my case, a dotted line separator). Like @Michael_B suggested, the key is using display:flex on the row container and at least making sure your middle container on the row has a flex-grow value of at least 1 higher than the outer containers (if outer containers don't have any flex-grow properties applied, middle container only needs 1 for flex-grow).

Here's a pic of what I was trying to do and sample code for how I solved it.

.row {
  background: lightgray;
  height: 30px;
  width: 100%;
  display: flex;
  align-items:flex-end;
  margin-top:5px;
}
.left {
  background:lightblue;
}
.separator{
  flex-grow:1;
  border-bottom:dotted 2px black;
}
.right {
  background:coral;
}

<div class="row">
  <div class="left">Left</div>
  <div class="separator"></div>
  <div class="right">Right With Text</div>
</div>
<div class="row">
  <div class="left">Left With More Text</div>
  <div class="separator"></div>
  <div class="right">Right</div>
</div>
<div class="row">
  <div class="left">Left With Text</div>
  <div class="separator"></div>
  <div class="right">Right With More Text</div>
</div>

for all views (you need dba privileges for this query)

select view_name from dba_views

for all accessible views (accessible by logged user)

select view_name from all_views

for views owned by logged user

select view_name from user_views

Here is a simple solution:

import pandas as pd
# convert the timestamp column to datetime
df['timestamp'] = pd.to_datetime(df['timestamp'])

# extract hour from the timestamp column to create an time_hour column
df['time_hour'] = df['timestamp'].dt.hour

I think the original answer is not exactly correct. append() changed both the slices and the underlying array even though the underlying array is changed but still shared by both of the slices.

As specified by the Go Doc:

A slice does not store any data, it just describes a section of an underlying array. (Link)

Slices are just wrapper values around arrays, meaning that they contain information about how they slice an underlying array which they use to store a set of data. Therefore, by default, a slice, when passed to another method, is actually passed by value, instead of reference/pointer even though they will still be using the same underlying array. Normally, arrays are also passed by value too, so I assume a slice points at an underlying array instead of store it as a value. Regarding your question, when you run passed your slice to the following function:

func Test(slice []int) {
    slice = append(slice, 100)
    fmt.Println(slice)
}

you actually passed a copy of your slice along with a pointer to the same underlying array.That means, the changes you did to the slice didn't affect the one in the main function. It is the slice itself which stores the information regarding how much of an array it slices and exposes to the public. Therefore, when you ran append(slice, 1000), while expanding the underlying array, you also changed slicing information of slice too, which was kept private in your Test() function.

However, if you have changed your code as follows, it might have worked:

func main() {
    for i := 0; i < 7; i++ {
        a[i] = i
    }

    Test(a)
    fmt.Println(a[:cap(a)])
}

The reason is that you expanded a by saying a[:cap(a)] over its changed underlying array, changed by Test() function. As specified here:

You can extend a slice's length by re-slicing it, provided it has sufficient capacity. (Link)

You can do something like this to read 10 bytes:

char buffer[10];
read(STDIN_FILENO, buffer, 10);

remember read() doesn't add '\0' to terminate to make it string (just gives raw buffer).

To read 1 byte at a time:

char ch;
while(read(STDIN_FILENO, &ch, 1) > 0)
{
 //do stuff
}

and don't forget to #include <unistd.h>, STDIN_FILENO defined as macro in this file.

There are three standard POSIX file descriptors, corresponding to the three standard streams, which presumably every process should expect to have:

Integer value   Name
       0        Standard input (stdin)
       1        Standard output (stdout)
       2        Standard error (stderr)

So instead STDIN_FILENO you can use 0.

Edit:
In Linux System you can find this using following command:

$ sudo grep 'STDIN_FILENO' /usr/include/* -R | grep 'define'
/usr/include/unistd.h:#define   STDIN_FILENO    0   /* Standard input.  */

Notice the comment /* Standard input. */

To see a frequency count for column two (for example):

awk -F '\t' '{print $2}' * | sort | uniq -c | sort -nr

fileA.txt

z    z    a
a    b    c
w    d    e

fileB.txt

t    r    e
z    d    a
a    g    c

fileC.txt

z    r    a
v    d    c
a    m    c

Result:

  3 d
  2 r
  1 z
  1 m
  1 g
  1 b

This function allows you to get the date and time in lots of formats (see the bottom of this post).

# Get the current date or time
def getdatetime(timedateformat='complete'):
    from datetime import datetime
    timedateformat = timedateformat.lower()
    if timedateformat == 'day':
        return ((str(datetime.now())).split(' ')[0]).split('-')[2]
    elif timedateformat == 'month':
        return ((str(datetime.now())).split(' ')[0]).split('-')[1]
    elif timedateformat == 'year':
        return ((str(datetime.now())).split(' ')[0]).split('-')[0]
    elif timedateformat == 'hour':
        return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[0]
    elif timedateformat == 'minute':
        return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[1]
    elif timedateformat == 'second':
        return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[2]
    elif timedateformat == 'millisecond':
        return (str(datetime.now())).split('.')[1]
    elif timedateformat == 'yearmonthday':
        return (str(datetime.now())).split(' ')[0]
    elif timedateformat == 'daymonthyear':
        return ((str(datetime.now())).split(' ')[0]).split('-')[2] + '-' + ((str(datetime.now())).split(' ')[0]).split('-')[1] + '-' + ((str(datetime.now())).split(' ')[0]).split('-')[0]
    elif timedateformat == 'hourminutesecond':
        return ((str(datetime.now())).split(' ')[1]).split('.')[0]
    elif timedateformat == 'secondminutehour':
        return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[2] + ':' + (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[1] + ':' + (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[0]
    elif timedateformat == 'complete':
        return str(datetime.now())
    elif timedateformat == 'datetime':
        return (str(datetime.now())).split('.')[0]
    elif timedateformat == 'timedate':
        return ((str(datetime.now())).split('.')[0]).split(' ')[1] + ' ' + ((str(datetime.now())).split('.')[0]).split(' ')[0]

To obtain the time or date, just use getdatetime("<TYPE>"), replacing <TYPE> with one of the following arguments:

There are several causes for this error.

MySQL/MariaDB related:

• wait_timeout - Time in seconds that the server waits for a connection to become active before closing it.
• interactive_timeout - Time in seconds that the server waits for an interactive connection.
• max_allowed_packet - Maximum size in bytes of a packet or a generated/intermediate string. Set as large as the largest BLOB, in multiples of 1024.

Example of my.cnf:

[mysqld]
# 8 hours
wait_timeout = 28800
# 8 hours
interactive_timeout = 28800
max_allowed_packet = 256M

Server related:

• Your server has full memory - check info about RAM with free -h

Framework related:

• Check settings of your framework. Django for example use CONN_MAX_AGE (see docs)

How to debug it:

• Check values of MySQL/MariaDB variables.
  • with sql: SHOW VARIABLES LIKE '%time%';
  • command line: mysqladmin variables
• Turn on verbosity for errors:
  • MariaDB: log_warnings = 4
  • MySQL: log_error_verbosity = 3
• Check docs for more info about the error

Your "bad" output is UTF-8 displayed as CP1252.

On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:

df.to_csv('file.csv',encoding='utf-8-sig')

That encoder will add the BOM.

Having run both queries on a SQL Server 2012 instance, I can confirm the first query was fastest in my case.

The query with the LIKE keyword showed a clustered index scan.

The CONTAINS also had a clustered index scan with additional operators for the full text match and a merge join.

In view file (HTML or EJS)

<div ng-repeat="item in vm.itemList  | filter: myFilter > </div>

and In Controller

$scope.myFilter = function(item) {
return (item.propertyA === 'value' || item.propertyA === 'value');
}

They're already ints. Why not just use subtraction?

compare = a - b;

Note that Integer.compareTo() doesn't necessarily return only -1, 0 or 1 either.

I keep this answer which is useful for other cases, but @trutheality answer seems to be the most simple and direct way.

You can use DateFormatSymbols

DateFormatSymbols(Locale.FRENCH).getMonths()[month]; // FRENCH as an example

You have to read the API carefully for this methods. Sometimes you can get confused very easily.

It is either:

if (B.class.isInstance(view))

API says: Determines if the specified Object (the parameter) is assignment-compatible with the object represented by this Class (The class object you are calling the method at)

or:

if (B.class.isAssignableFrom(view.getClass()))

API says: Determines if the class or interface represented by this Class object is either the same as, or is a superclass or superinterface of, the class or interface represented by the specified Class parameter

or (without reflection and the recommended one):

if (view instanceof B)

In case anyone else ends up here with my issue with a DB First Entity Framework setup.

Long story short, I needed to overload the Entities constructor to accept a connection string, the reason being the ability to use Asp.Net Core dependency injection container pulling the connection string from appsettings.json, rather than magically getting it from the App.config file when calling the parameterless constructor.

I forgot to add the calls to initialize my DbSets in the new overload. So the auto-generated parameter-less constructor looked something like this:

    public MyEntities()
        : base("name=MyEntity")
    {
        Set1 = Set<MyDbSet1>();
        Set2 = Set<MyDbSet2>();
    }

And my new overload looked like this:

    public MyEntities(string connectionString)
        : base(connectionString)
    {
    }

The solution was to add those initializers that the auto-generated code takes care of, a simple missed step:

     public MyEntities(string connectionString)
        : base(connectionString)
    {
        Set1 = Set<MyDbSet1>();
        Set2 = Set<MyDbSet2>();
    }

This really threw me for a loop because some calls in our Respository that used the DbContext worked fine (the ones that didn't need those initialized DBSets), and the others throw the runtime error described in the OP.

Actually, you have to use the anchor # to play with this. If you reverse engineer the Gmail url system, you'll find

https://mail.google.com/mail/u/0/#inbox
https://mail.google.com/mail/u/0/#inbox?compose=new

Everything after # is the part your want to load in your page, then you just have to chose where to load it.

By the way, using document.location by adding a #something won't refresh your page.

The most similar C# Select analogue would be a map function. Just use:

var ids = selectedFruits.map(fruit => fruit.id);

to select all ids from selectedFruits array.

It doesn't require any external dependencies, just pure JavaScript. You can find map documentation here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map

Resizing canvas using css is not a good idea. It should be done using Javascript. See the below function which does it

function setCanvas(){

   var canvasNode = document.getElementById('xCanvas');

   var pw = canvasNode.parentNode.clientWidth;
   var ph = canvasNode.parentNode.clientHeight;

   canvasNode.height = pw * 0.8 * (canvasNode.height/canvasNode.width);  
   canvasNode.width = pw * 0.8;
   canvasNode.style.top = (ph-canvasNode.height)/2 + "px";
   canvasNode.style.left = (pw-canvasNode.width)/2 + "px";


}

Check, you might have written this statement wrong.

I have also just started java and was facing the same error and it was occuring as i didn't put [] after args. so check ur statment.

Simple...Blackbox testing is otherwise known as Integration testing or smoke-screen testing . This is mostly applied in a distributed environment which rely on event-driven architecture. You test a service based on another service to see all possible scenarios. Here you cannot completely forecast all possible output because each component of the SOA/Enterprise app are meant to function autonomously. This can be referred to as High-Level testing

while

White box testing refers to unit-testing. where all expected scenarios and output can be effectively forecasted. i.e Input and expected output.This can be referred to as Low-level testing

1. First download WinBGIm from http://winbgim.codecutter.org/ Extract it.
2. Copy graphics.h and winbgim.h files in include folder of your compiler directory
3. Copy libbgi.a to lib folder of your compiler directory
4. In code::blocks open Settings >> Compiler and debugger >>linker settings click Add button in link libraries part and browse and select libbgi.a file
5. In right part (i.e. other linker options) paste commands -lbgi -lgdi32 -lcomdlg32 -luuid -loleaut32 -lole32

Here's a cross browser function I have in my standard library:

function getCursorPos(input) {
    if ("selectionStart" in input && document.activeElement == input) {
        return {
            start: input.selectionStart,
            end: input.selectionEnd
        };
    }
    else if (input.createTextRange) {
        var sel = document.selection.createRange();
        if (sel.parentElement() === input) {
            var rng = input.createTextRange();
            rng.moveToBookmark(sel.getBookmark());
            for (var len = 0;
                     rng.compareEndPoints("EndToStart", rng) > 0;
                     rng.moveEnd("character", -1)) {
                len++;
            }
            rng.setEndPoint("StartToStart", input.createTextRange());
            for (var pos = { start: 0, end: len };
                     rng.compareEndPoints("EndToStart", rng) > 0;
                     rng.moveEnd("character", -1)) {
                pos.start++;
                pos.end++;
            }
            return pos;
        }
    }
    return -1;
}

Use it in your code like this:

var cursorPosition = getCursorPos($('#myTextarea')[0])

Here's its complementary function:

function setCursorPos(input, start, end) {
    if (arguments.length < 3) end = start;
    if ("selectionStart" in input) {
        setTimeout(function() {
            input.selectionStart = start;
            input.selectionEnd = end;
        }, 1);
    }
    else if (input.createTextRange) {
        var rng = input.createTextRange();
        rng.moveStart("character", start);
        rng.collapse();
        rng.moveEnd("character", end - start);
        rng.select();
    }
}

Check whether the USERNAME is correct, for me a new USERNAME got created with my proxy extension.

That should be:

<div ng-bind-html="trustedHtml"></div>

plus in your controller:

$scope.html = '<ul><li>render me please</li></ul>';
$scope.trustedHtml = $sce.trustAsHtml($scope.html);

instead of old syntax, where you could reference $scope.html variable directly:

<div ng-bind-html-unsafe="html"></div>

As several commenters pointed out, $sce has to be injected in the controller, otherwise you will get $sce undefined error.

 var myApp = angular.module('myApp',[]);

 myApp.controller('MyController', ['$sce', function($sce) {
    // ... [your code]
 }]);

If you want to keep the general styling (rounded corners etc.) and just change the background color then I use the backgroundTint property

android:backgroundTint="@android:color/holo_green_light"

This problem happens because IIS does not know about woff and woff2 file mime types.

Solution 1:

Add these lines in your web.config project:

 <system.webServer>
  ...
  </modules>
    <staticContent>
      <remove fileExtension=".woff" />
      <mimeMap fileExtension=".woff" mimeType="application/font-woff" />
      <remove fileExtension=".woff2" />
      <mimeMap fileExtension=".woff2" mimeType="font/woff2" />
    </staticContent>

Solution 2:

On IIS project page:

Step 1: Go to your project IIS home page and double click on MIME Types button:

Step 2: Click on Add button from Actions menu:

Step 3: In the middle of the screen appears a window and in this window you need to add the two lines from solution 1:

Try finding the Service running on the PID that is blocking the service from Task manager->Services

In case this isn't of help go to Task Manager->Services Go to the Services button on bottom right of window and stop the Web Deployment Agent Service. Retry starting Apache . That might solve the problem.

You can do the following (which I find trivial, but its actually correct). For anyone trying to find how to initialize a two-dimensional array in TypeScript (like myself).

Let's assume that you want to initialize a two-dimensional array, of any type. You can do the following

const myArray: any[][] = [];

And later, when you want to populate it, you can do the following:

myArray.push([<your value goes here>]);

A short example of the above can be the following:

const myArray: string[][] = [];
myArray.push(["value1", "value2"]);

Copying to the clipboard is a tricky task to do in Javascript in terms of browser compatibility. The best way to do it is using a small flash. It will work on every browser. You can check it in this article.

Here's how to do it for Internet Explorer:

function copy (str)
{
    //for IE ONLY!
    window.clipboardData.setData('Text',str);
}

You can solve this issue by calling a:link and a:visited selectors together. And follow it with a:hover selector.

a:link, a:visited
{color: gray;}
a:hover
{color: skyblue;}

You can safely delete the WSDL cache files. If you wish to prevent future caching, use:

ini_set("soap.wsdl_cache_enabled", 0);

or dynamically:

$client = new SoapClient('http://somewhere.com/?wsdl', array('cache_wsdl' => WSDL_CACHE_NONE) );

RabbitMQ has 2 things under queue

1. Delete
2. Purge

Delete - will delete the queue

Purge - This will empty the queue (meaning removes messages from the queue but queue still exists)

I am using Intellij Idea 2017 and I got into the same problem. What solved the problem for me was to simply

1. close the project in intelliJ
2. File -> New -> project from existing resources
3. use Import from external model (if any)
4. open the project again.

Try this:

public  boolean isNumber(String str)
{       
    short count = 0;
    char chc[]  = {'0','1','2','3','4','5','6','7','8','9','.','-','+'};
    for (char c : str.toCharArray())
    {   
        for (int i = 0;i < chc.length;i++)
        {
            if( c  == chc[i]){
                count++;        
            }
         }                      
    }
    if (count != str.length() ) 
        return false;
    else
        return true;
}

You can create a new row with $ in your data frame corresponding to the Means

DF$Mean <- rowMeans(DF[,2:4])

<button type ="button" onclick="location.href='@Url.Action("viewname","Controllername")'"> Button name</button>

for e.g ,

<button type="button" onclick="location.href='@Url.Action("register","Home")'">Register</button>

In Spring 4 Web MVC. You can use @SessionAttribute in the method with @SessionAttributes in Controller level

@Controller
@SessionAttributes("SessionKey")
public class OrderController extends BaseController {

    GetMapping("/showOrder")
    public String showPage(@SessionAttribute("SessionKey") SearchCriteria searchCriteria) {
     // method body
}

You'll want to use a URL in the following format...

https://api.whatsapp.com/send?text=text

Then you can have it send whatever text you'd like. You also have the option to specify a phone number...

https://api.whatsapp.com/send?text=text&phone=1234

What you CANNOT DO is use the following:

https://wa.me/send?text=text

You will get...

We couldn't find the page you were looking for

wa.me, though, will work if you supply both a phone number and text. But, for the most part, if you're trying to make a sharing link, you really don't want to indicate the phone number, because you want the user to select someone. In that event, if you don't supply the number and use wa.me as URL, all of your sharing links will fail. Please use app.whatsapp.com.

The naive algorithm, which is what you've got once you correct it as noted in comments, is O(n^3).

There do exist algorithms that reduce this somewhat, but you're not likely to find an O(n^2) implementation. I believe the question of the most efficient implementation is still open.

See this wikipedia article on Matrix Multiplication for more information.

I dont think youre returning json object from server. just a string.

you need the dataType of the return object to be json

The thing to understand here is that:

The constructor ViewClassName(Context context, AttributeSet attrs ) is called when inflating the customView via xml. You see you are not using the new keyword to instantiate your object i.e. you are not doing new GhostSurfaceCameraView(). Doing this you are calling the first constructor i.e. public View (Context context).

Whereas when inflating view from XML, i.e. when using setContentView(R.layout.ghostviewscreen); or using findViewById, you, NO, not you!, the android system calls the ViewClassName(Context context, AttributeSet attrs ) constructor.

This is clear when reading the documentation : "Constructor that is called when inflating a view from XML." See: https://developer.android.com/reference/android/view/View.html#View(android.content.Context,%20android.util.AttributeSet)

Hence, never forget basic polymorphism and never forget reading through the documentation. It saves a ton of headache.

What kind of processing are you trying to do? You can do XmlDocument doc = new XmlDocument(); followed by doc.Load(filename). Then the XML document can be parsed in memory.

But here is an important excerpt from the docs:

If you have multiple Dockerfile steps that use different files from your context, COPY them individually, rather than all at once. This ensures that each step’s build cache is only invalidated (forcing the step to be re-run) if the specifically required files change.

                    ->where('votes', '>', 100)

                    ->get();

If you're inserting text content in your document in a location where text content is expected¹, you typically only need to escape the same characters as you would in XML. Inside of an element, this just includes the entity escape ampersand & and the element delimiter less-than and greater-than signs < >:

& becomes &
< becomes &lt;
> becomes &gt;

Inside of attribute values you must also escape the quote character you're using:

" becomes "
' becomes '

In some cases it may be safe to skip escaping some of these characters, but I encourage you to escape all five in all cases to reduce the chance of making a mistake.

If your document encoding does not support all of the characters that you're using, such as if you're trying to use emoji in an ASCII-encoded document, you also need to escape those. Most documents these days are encoded using the fully Unicode-supporting UTF-8 encoding where this won't be necessary.

In general, you should not escape spaces as  .   is not a normal space, it's a non-breaking space. You can use these instead of normal spaces to prevent a line break from being inserted between two words, or to insert          extra        space       without it being automatically collapsed, but this is usually a rare case. Don't do this unless you have a design constraint that requires it.

¹ By "a location where text content is expected", I mean inside of an element or quoted attribute value where normal parsing rules apply. For example: <p>HERE</p> or <p title="HERE">...</p>. What I wrote above does not apply to content that has special parsing rules or meaning, such as inside of a script or style tag, or as an element or attribute name. For example: <NOT-HERE>...</NOT-HERE>, <script>NOT-HERE</script>, <style>NOT-HERE</style>, or <p NOT-HERE="...">...</p>.

In these contexts, the rules are more complicated and it's much easier to introduce a security vulnerability. I strongly discourage you from ever inserting dynamic content in any of these locations. I have seen teams of competent security-aware developers introduce vulnerabilities by assuming that they had encoded these values correctly, but missing an edge case. There's usually a safer alternative, such as putting the dynamic value in an attribute and then handling it with JavaScript.

If you must, please read the Open Web Application Security Project's XSS Prevention Rules to help understand some of the concerns you will need to keep in mind.

No, that's not possible. The port is not part of the hostname, so it has no meaning in the hosts-file.

My approach:

• define a default constraint on the ModDate column with a value of GETDATE() - this handles the INSERT case

• have a AFTER UPDATE trigger to update the ModDate column

Something like:

CREATE TRIGGER trg_UpdateTimeEntry
ON dbo.TimeEntry
AFTER UPDATE
AS
    UPDATE dbo.TimeEntry
    SET ModDate = GETDATE()
    WHERE ID IN (SELECT DISTINCT ID FROM Inserted)

SELECT 
    MIN(Column), MAX(Column), UserId 
FROM 
    Table_Name
WHERE 
    (Conditions)
GROUP BY 
    UserId DESC

or

SELECT        
    MAX(Column) 
FROM            
    TableName
WHERE        
    (Filter)

UNION ALL

SELECT        
    MIN(Column)
FROM            
    TableName AS Tablename1
WHERE        
    (Filter)
ORDER BY 
    Column

Building on Matteo Furlans design, when he said "most dynamic array implementations work by starting off with an array of some (small) default size, then whenever you run out of space when adding a new element, double the size of the array". The difference in the "work in progress" below is that it doesn't double in size, it aims at using only what is required. I have also omitted safety checks for simplicity...Also building on brimboriums idea, I have tried to add a delete function to the code...

What directory is file.txt in? cron runs jobs in your home directory, so unless your script cds somewhere else, that's where it's going to look for/create file.txt.

EDIT: When you refer to a file without specifying its full path (e.g. file.txt, as opposed to the full path /home/myUser/scripts/file.txt) in shell, it's taken that you're referring to a file in your current working directory. When you run a script (whether interactively or via crontab), the script's working directory has nothing at all to do with the location of the script itself; instead, it's inherited from whatever ran the script.

Thus, if you cd (change working directory) to the directory the script's in and then run it, file.txt will refer to a file in the same directory as the script. But if you don't cd there first, file.txt will refer to a file in whatever directory you happen to be in when you ran the script. For instance, if your home directory is /home/myUser, and you open a new shell and immediately run the script (as scripts/test.sh or /home/myUser/scripts/test.sh; ./test.sh won't work), it'll touch the file /home/myUser/file.txt because /home/myUser is your current working directory (and therefore the script's).

When you run a script from cron, it does essentially the same thing: it runs it with the working directory set to your home directory. Thus all file references in the script are taken relative to your home directory, unless the script cds somewhere else or specifies an absolute path to the file.

With SimpleDateFormat. And steps are -

1. Create your date pattern string
2. Create SimpleDateFormat Object
3. And parse with it.
4. It will return Date Object.

There is an excellent three part guide for Histogram Adjustments in MATLAB (broken original link, archive.org link), the first part is on Histogram Stretching.

Use display instead of visibility. display: none for invisible and no setting for visible.

simply use..

Just go to the project Properties->Project Facets

1. Uncheck the dynamic module, click apply.

2. Maven->update the project.

Use the following for multiple .cpp files

g++ *.cpp
./a.out

INSERT
INTO    Employee 
        (emp_id, emp_name, emp_address, emp_state, emp_position, emp_manager)
SELECT  '001', 'John Doe', '1 River Walk, Green Street', state_id, position_id, manager_id
FROM    dual
JOIN    state s
ON      s.state_name = 'New York'
JOIN    positions p
ON      p.position_name = 'Sales Executive'
JOIN    manager m
ON      m.manager_name = 'Barry Green'

Note that but a single spelling mistake (or an extra space) will result in a non-match and nothing will be inserted.

To produce the output in your comment to your post, this will do it:

use strict;
use warnings;

my @other_array = (0,0,0,1,2,2,3,3,3,4);
my @array;
my %uniqs;

$uniqs{$_}++ for @other_array;

foreach (keys %uniqs) { $array[$_]=$uniqs{$_} }

print "array[$_] = $array[$_]\n" for (0..$#array);

Output:

   array[0] = 3
   array[1] = 1
   array[2] = 2
   array[3] = 3
   array[4] = 1

This is different than your stated algorithm of producing a parallel array with zero values, but it is a more Perly way of doing it...

If you must have a parallel array that is the same size as your first array with the elements initialized to 0, this statement will dynamically do it: @array=(0) x scalar(@other_array); but really, you don't need to do that.

Came here to see how to append an item to a 2D array, but the title of the thread is a bit misleading because it is exploring an issue with the appending.

The easiest way I found to append to a 2D list is like this:

list=[[]]

list.append((var_1,var_2))

This will result in an entry with the 2 variables var_1, var_2. Hope this helps!

The problem with your code is that when you do

 list[] == "e"

you're asking if the array object (not the contents) is equal to the string "e", which is clearly not the case.

You'll want to iterate over the contents in order to do the check you want:

 for(String element : list) {
      if (element.equals("e")) {
           // do something here
      }
 }

If you are using an old version of FFMPEG and you cant upgrade you can do the following:

ffmpeg -i PATH/VIDEO_FILE_NAME.mp4 -i PATH/AUDIO_FILE_NAME.mp3 -vcodec copy -shortest DESTINATION_PATH/NEW_VIDEO_FILE_NAME.mp4

Notice that I used -vcodec

Bounds - x:0, y:0, width: 20, height: 40 is a static
Frame - x:60, y:20, width: 45, height: 45 is a dynamic based on inner bounds.

One more illustration to show a difference between frame and bounds. At this example:

• View B is a subview of View A
• View B was moved to x:60, y: 20
• View B was rotated 45 degrees

You need to put the entire ternary expression in parenthesis. Unfortunately that means you can't use "@:", but you could do something like this:

@(deletedView ? "Deleted" : "Created by")

Razor currently supports a subset of C# expressions without using @() and unfortunately, ternary operators are not part of that set.

If you've got ther JSON data coming in as a string (e.g. '[{"id":1,"name":"Charles"},{"id":8,"name":"John"},{"id":13,"name":"Sally"}]')

Then I'd use JSON.net and use Linq to JSON to get the values out...

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

    if (Request["items"] != null)
    {
        var items = Request["items"].ToString(); // Get the JSON string
        JArray o = JArray.Parse(items); // It is an array so parse into a JArray
        var a = o.SelectToken("[0].name").ToString(); // Get the name value of the 1st object in the array
        // a == "Charles"
    }
}
}

In Visual Studio 2010 (until 2019 and possibly future versions) you can add the manifest file to your project.

Right click your project file on the Solution Explorer, select Add, then New item (or CTRL+SHIFT+A). There you can find Application Manifest File.

The file name is app.manifest.

I've created an NPM module, which allows you to share locally-stored data across domains: https://www.npmjs.com/package/cookie-toss

By using an iframe hosted on Domain A, you can store all of your user data on Domain A, and reference that data by posting requests to the Domain A iframe.

Thus, Domains B, C, etc. can inject the iframe and post requests to it to store and access the desired data. Domain A becomes the hub for all shared data.

With a domain whitelist inside of Domain A, you can ensure only your dependent sites can access the data on Domain A.

The trick is to have the code inside of the iframe on Domain A which is able to recognize which data is being requested. The README in the above NPM module goes more in depth into the procedure.

Hope this helps!

Giving the sql service account 'NT SERVICE\MSSQLSERVER' "Full Control" of the database files

If you have access to the server files/folders you can try this solution that worked for me:

SQL Server 2012 on Windows Server 2008 R2

1. Right click the database (mdf/ldf) file or folder and select "Properties".
2. Select "Security" tab and click the "Edit" button.
3. Click the "Add" button.
4. Enter the object name to select as 'NT SERVICE\MSSQLSERVER' and click "Check Names" button.
5. Select the MSSQLSERVER (RDN) and click the "OK" button twice.
6. Give this service account "Full control" to the file or folder.
7. Back in SSMS, right click the database and select "Properties".
8. Under "Options", scroll down to the "State" section and change "Database Read-Only" from "True" to "False".

I removed the old web library such that are spring framework libraries. And build a new path of the libraries. Then it works.

Sorry, most efficient way with out stuffing your proj file is.

1. right click the file.
2. goto properties
3. where Build Action option is set it to NONE.
4. Do a build (yes you may get build error if you do even better)
5. go back to properties of that file
6. set Build Action option is set it back to Compile.

7. rebuild.

8. Congratulate your self for being smarter than everyone else and not ****ing you project. For me this exercise took under 10 seconds. Where as manually trying to input the compile... line into the csproj not only can render your project unusable but it is also impossible to maintain on large scale application. Better to keep source version control software to do the updates. If you need to cross merge branches then doing the above is amazing :).

It depends on the language and the exact use. For instance, in C# 1 it made no difference. In C# 2, if the local variable is captured by an anonymous method (or lambda expression in C# 3) it can make a very signficant difference.

Example:

using System;
using System.Collections.Generic;

class Test
{
    static void Main()
    {
        List<Action> actions = new List<Action>();

        int outer;
        for (int i=0; i < 10; i++)
        {
            outer = i;
            int inner = i;
            actions.Add(() => Console.WriteLine("Inner={0}, Outer={1}", inner, outer));
        }

        foreach (Action action in actions)
        {
            action();
        }
    }
}

Output:

Inner=0, Outer=9
Inner=1, Outer=9
Inner=2, Outer=9
Inner=3, Outer=9
Inner=4, Outer=9
Inner=5, Outer=9
Inner=6, Outer=9
Inner=7, Outer=9
Inner=8, Outer=9
Inner=9, Outer=9

The difference is that all of the actions capture the same outer variable, but each has its own separate inner variable.

Make sure this matches in the module:app and module:lib:

android {
    compileSdkVersion 23
    buildToolsVersion '22.0.1'
    packagingOptions {
    }

    defaultConfig {
        minSdkVersion 17
        targetSdkVersion 23
        versionCode 11
        versionName "2.1"
    }

function createOfferUrlArray($Offer) {
    $offerArray = array();
    foreach ($Offer as $key => $value) { 
        $offerArray[$key] = $value[4];
    }
    return $offerArray;
}

or

function createOfferUrlArray($offer) {
    foreach ( $offer as &$value ) {
        $value = $value[4];
    }
    unset($value);
    return $offer;
}

Based on this questions answer I implemented a class you can use to read a file synchronously line-by-line with fs.readSync(). You can make this "pause" and "resume" by using a Q promise (jQuery seems to require a DOM so cant run it with nodejs):

var fs = require('fs');
var Q = require('q');

var lr = new LineReader(filenameToLoad);
lr.open();

var promise;
workOnLine = function () {
    var line = lr.readNextLine();
    promise = complexLineTransformation(line).then(
        function() {console.log('ok');workOnLine();},
        function() {console.log('error');}
    );
}
workOnLine();

complexLineTransformation = function (line) {
    var deferred = Q.defer();
    // ... async call goes here, in callback: deferred.resolve('done ok'); or deferred.reject(new Error(error));
    return deferred.promise;
}

function LineReader (filename) {      
  this.moreLinesAvailable = true;
  this.fd = undefined;
  this.bufferSize = 1024*1024;
  this.buffer = new Buffer(this.bufferSize);
  this.leftOver = '';

  this.read = undefined;
  this.idxStart = undefined;
  this.idx = undefined;

  this.lineNumber = 0;

  this._bundleOfLines = [];

  this.open = function() {
    this.fd = fs.openSync(filename, 'r');
  };

  this.readNextLine = function () {
    if (this._bundleOfLines.length === 0) {
      this._readNextBundleOfLines();
    }
    this.lineNumber++;
    var lineToReturn = this._bundleOfLines[0];
    this._bundleOfLines.splice(0, 1); // remove first element (pos, howmany)
    return lineToReturn;
  };

  this.getLineNumber = function() {
    return this.lineNumber;
  };

  this._readNextBundleOfLines = function() {
    var line = "";
    while ((this.read = fs.readSync(this.fd, this.buffer, 0, this.bufferSize, null)) !== 0) { // read next bytes until end of file
      this.leftOver += this.buffer.toString('utf8', 0, this.read); // append to leftOver
      this.idxStart = 0
      while ((this.idx = this.leftOver.indexOf("\n", this.idxStart)) !== -1) { // as long as there is a newline-char in leftOver
        line = this.leftOver.substring(this.idxStart, this.idx);
        this._bundleOfLines.push(line);        
        this.idxStart = this.idx + 1;
      }
      this.leftOver = this.leftOver.substring(this.idxStart);
      if (line !== "") {
        break;
      }
    }
  }; 
}

From another answer:

A little history

Remember, there is nothing inherently special about $. It is a variable name just like any other. In earlier days, people used to write code using document.getElementById. Because JavaScript is case-sensitive, it was normal to make a mistake while writing document.getElementById. Should I capital 'b' of 'by'? Should I capital 'i' of Id? You get the drift. Because functions are first-class citizens in JavaScript, you can always do this:

var $ = document.getElementById; //freedom from document.getElementById!

When Prototype library arrived, they named their function, which gets the DOM elements, as '$'. Almost all the JavaScript libraries copied this idea. Prototype also introduced a $$ function to select elements using CSS selector.

jQuery also adapted $ function but expanded to make it accept all kinds of 'selectors' to get the elements you want. Now, if you are already using Prototype in your project and wanted to include jQuery, you will be in problem as '$' could either refer to Prototype's implementation OR jQuery's implementation. That's why jQuery has the option of noConflict so that you can include jQuery in your project which uses Prototype and slowly migrate your code. I think this was a brilliant move on John's part! :)

There are new methods added to java.util.Arrays to convert an array into a Java 8 stream which can then be used for summing etc.

int sum =  Arrays.stream(myIntArray)
                 .sum();

Multiplying two arrays is a little more difficult because I can't think of a way to get the value AND the index at the same time as a Stream operation. This means you probably have to stream over the indexes of the array.

//in this example a[] and b[] are same length
int[] a = ...
int[] b = ...

int[] result = new int[a.length];

IntStream.range(0, a.length)
         .forEach(i -> result[i] = a[i] * b[i]);

EDIT

Commenter @Holger points out you can use the map method instead of forEach like this:

int[] result = IntStream.range(0, a.length).map(i -> a[i] * b[i]).toArray();

This is the code I'm using to embed images into HTML mail and PDF documents.

<?php
$logo_path = 'http://localhost/img/logo.jpg';
$type = pathinfo($logo_path, PATHINFO_EXTENSION);
$image_contents = file_get_contents($logo_path);
$image64 = 'data:image/' . $type . ';base64,' . base64_encode($image_contents);

echo '<img src="' . $image64 .'" />';
?>

TL;DR

.col-X-Y means on screen size X and up, stretch this element to fill Y columns.

Bootstrap provides a grid of 12 columns per .row, so Y=3 means width=25%.

xs, sm, md, lg are the sizes for smartphone, tablet, laptop, desktop respectively.

The point of specifying different widths on different screen sizes is to let you make things larger on smaller screens.

Example

<div class="col-lg-6 col-xs-12">

Meaning: 50% width on Desktops, 100% width on Mobile, Tablet, and Laptop.

My response is a little bit old but for my the only solution was adding multiDexEnabled option in defaultConfig like this:

    android{
        ...
        defaultConfig{
            ...
            multiDexEnabled true
        }
    }

If this does not work for you try adding this piece of code:

    configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '26.1.0'
            }
        }
    }
}

My error was related to a problem with different libraries versions and this made the trick.

I hope this can help somebody :)

This happened to me as well. The fix was wrapping it in HTML tags. Then I saved the file as /var/www/html/info.php and ran http://localhost/info.php in the browser. That's it.

<html>
    <body>
        <?php
            phpinfo();
        ?>
    </body>
</html>

sysv-rc-conf is an alternate option for Ubuntu.

sudo apt-get install sysv-rc-conf

sysv-rc-conf --list xxxx

One solution to the problem that I found was to just set the width in inches. So far I've only tested/confirmed this working in Chrome. It worked well for what I was using it for (to print out an 8.5 x 11 sheet)

@media print {
    .printEl { 
        width: 8.5in;
        height: 11in;
    }
}

If you use a TCPServer, UDPServer or their subclasses in the SocketServer module, you can set this class variable (before instanciating a server):

SocketServer.TCPServer.allow_reuse_address = True

(via SocketServer.ThreadingTCPServer - Cannot bind to address after program restart )

This causes the init (constructor) to:

 if self.allow_reuse_address:
     self.socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

Hmm, I think that what you might be wanting to do is print all the keys in the dictionary and their respective values?

If so you want the following:

for key in mydic:
  print "the key name is" + key + "and its value is" + mydic[key]

Make sure you use +'s instead of ,' as well. The comma will put each of those items on a separate line I think, where as plus will put them on the same line.

itoa() function is not defined in ANSI-C, so not implemented by default for some platforms (Reference Link).

s(n)printf() functions are easiest replacement of itoa(). However itoa (integer to ascii) function can be used as a better overall solution of integer to ascii conversion problem.

itoa() is also better than s(n)printf() as performance depending on the implementation. A reduced itoa (support only 10 radix) implementation as an example: Reference Link

Another complete itoa() implementation is below (Reference Link):

#include <stdbool.h> 
#include <string.h>

// A utility function to reverse a string 
char *reverse(char *str)
{
  char *p1, *p2;

  if (! str || ! *str)
        return str;
  for (p1 = str, p2 = str + strlen(str) - 1; p2 > p1; ++p1, --p2)
  {
        *p1 ^= *p2;
        *p2 ^= *p1;
        *p1 ^= *p2;
  }
  return str;
}
// Implementation of itoa() 
char* itoa(int num, char* str, int base) 
{ 
    int i = 0; 
    bool isNegative = false; 
  
    /* Handle 0 explicitely, otherwise empty string is printed for 0 */
    if (num == 0) 
    { 
        str[i++] = '0'; 
        str[i] = '\0'; 
        return str; 
    } 
  
    // In standard itoa(), negative numbers are handled only with  
    // base 10. Otherwise numbers are considered unsigned. 
    if (num < 0 && base == 10) 
    { 
        isNegative = true; 
        num = -num; 
    } 
  
    // Process individual digits 
    while (num != 0) 
    { 
        int rem = num % base; 
        str[i++] = (rem > 9)? (rem-10) + 'a' : rem + '0'; 
        num = num/base; 
    } 
  
    // If number is negative, append '-' 
    if (isNegative) 
        str[i++] = '-'; 
  
    str[i] = '\0'; // Append string terminator 
  
    // Reverse the string 
    reverse(str); 
  
    return str; 
} 

Another complete itoa() implementatiton: Reference Link

An itoa() usage example below (Reference Link):

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
 
int main()
{
    int a=54325;
    char buffer[20];
    itoa(a,buffer,2);   // here 2 means binary
    printf("Binary value = %s\n", buffer);
 
    itoa(a,buffer,10);   // here 10 means decimal
    printf("Decimal value = %s\n", buffer);
 
    itoa(a,buffer,16);   // here 16 means Hexadecimal
    printf("Hexadecimal value = %s\n", buffer);
    return 0;
}

No, absolutely positioning does not conflict with flex containers. Making an element be a flex container only affects its inner layout model, that is, the way in which its contents are laid out. Positioning affects the element itself, and can alter its outer role for flow layout.

That means that

• If you add absolute positioning to an element with display: inline-flex, it will become block-level (like display: flex), but will still generate a flex formatting context.

• If you add absolute positioning to an element with display: flex, it will be sized using the shrink-to-fit algorithm (typical of inline-level containers) instead of the fill-available one.

That said, absolutely positioning conflicts with flex children.

As it is out-of-flow, an absolutely-positioned child of a flex container does not participate in flex layout.

This error can also appear when python versions are mixed:

For example if any of the DLL to be loaded has been compiled using python 2.7.16 and you try to import with python 2.7.15 this error ImportError: DLL load failed: %1 is not a valid Win32 application. is thrown.

This is at least what I've found to be the problem in my case.

one has not been assigned so points to an unpredictable location. You should either place it on the stack:

Vector one;
one.a = 12;
one.b = 13;
one.c = -11

or dynamically allocate memory for it:

Vector* one = malloc(sizeof(*one))
one->a = 12;
one->b = 13;
one->c = -11
free(one);

Note the use of free in this case. In general, you'll need exactly one call to free for each call made to malloc.

As the first answer indicated, currently there is no way to rename components so we're all just talking about work-arounds! This is what i do:

1. Create the new component you liked.

   ng generate component newName

2. Use Visual studio code editor or whatever other editor to then conveniently move code/pieces side by side!

3. In Linux, use grep & sed (find & replace) to find/replaces references.

   grep -ir "oldname"

   cd your folder

   sed -i 's/oldName/newName/g' *

Allowing all certificates is very powerful but it could also be dangerous. If you would like to only allow valid certificates plus some certain certificates it could be done like this.

using (var httpClientHandler = new HttpClientHandler())
{
    httpClientHandler.ServerCertificateCustomValidationCallback = (message, cert, chain, sslPolicyErrors) => {
        if (sslPolicyErrors == SslPolicyErrors.None)
        {
            return true;   //Is valid
        }

        if (cert.GetCertHashString() == "99E92D8447AEF30483B1D7527812C9B7B3A915A7")
        {
            return true;
        }
        return false;
    };
    using (var httpClient = new HttpClient(httpClientHandler))
    {
        var httpResponse = httpClient.GetAsync("https://example.com").Result;
    }
}
