They're examples provided by the Android team, if you've already loaded Samples, you can import Home screen replacement sample by following these steps.

File > New > Other >Android > Android Sample Project > Android x.x > Home > Finish

But if you do not have samples loaded, then download it using the below steps

Windows > Android SDK Manager > chooses "Sample for SDK" for SDK you need it > Install package > Accept License > Install

Try this process, this may help you.

1. Create PNG image file of size 512x512 pixels
2. In menu, go to File -> New -> Image Asset
3. Select Image option in Asset type options
4. Click on Directory Box at right.
5. Drag image to source asset box
6. Click Next (Note: Existing launcher files will be overwritten)
7. Click Finish

***** NB: Icon type should be Launcher Icons (Adaptive and Legacy) *****

You can do this, you just need to circumvent the launcher.

In %appdata%\.minecraft\bin (or ~/.minecraft/bin on unixy systems), there is a minecraft.jar file. This is the actual game - the launcher runs this.

Invoke it like so:

java -Xms512m -Xmx1g -Djava.library.path=natives/ -cp "minecraft.jar;lwjgl.jar;lwjgl_util.jar" net.minecraft.client.Minecraft <username> <sessionID>

Set the working directory to .minecraft/bin.

To get the session ID, POST (request this page):

https://login.minecraft.net?user=<username>&password=<password>&version=13

You'll get a response like this:

1343825972000:deprecated:SirCmpwn:7ae9007b9909de05ea58e94199a33b30c310c69c:dba0c48e1c584963b9e93a038a66bb98

The fourth field is the session ID. More details here. Read those details, this answer is outdated

Here's an example of logging in to minecraft.net in C#.

This happened to me when an web request endpoint was switched to another server that accepted TLS1.2 requests only. Tried so many attempts mostly found on Stackoverflow like

1. Registry Keys ,
2. Added :
   System.Net.ServicePointManager.SecurityProtocol |= System.Net.SecurityProtocolType.Tls12; to Global.ASX OnStart,
3. Added in Web.config.
4. Updated .Net framework to 4.7.2 Still getting same Exception.

The exception received did no make justice to the actual problem I was facing and found no help from the service operator.

To solve this I have to add a new Cipher Suite TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 I have used IIS Crypto 2.0 Tool from here as shown below.

You can just use np.savetxt and access the np attribute .values:

np.savetxt(r'c:\data\np.txt', df.values, fmt='%d')

yields:

18 55 1 70
18 55 2 67
18 57 2 75
18 58 1 35
19 54 2 70

or to_csv:

df.to_csv(r'c:\data\pandas.txt', header=None, index=None, sep=' ', mode='a')

Note for np.savetxt you'd have to pass a filehandle that has been created with append mode.

I had the same problem. I think the best solution is to use log.exception, which will automatically print out stack trace and error message, such as:

try:
    pass
    log.info('Success')
except:
    log.exception('Failed')

Old school:

    int value = 28;
    for(int i = 1, j = 0; i < 256; i = i << 1, j++)
        System.out.println(j + " " + ((value & i) > 0 ? 1 : 0));

You're comparing the message with the empty string using ==.

First, your comparison is wrong because the message will be null (and not the empty string).

Second, it's wrong because Objects must be compared with equals() and not with ==.

Third, it's wrong because you should avoid scriptlets in JSP, and use the JSP EL, the JSTL, and other custom tags instead:

<c:id test="${!empty message}">
    <c:out value="${message}"/>
</c:if>

Adding 'playsinline' works for me on Iphone and Ipa if you don't mind your video being muted.

<video muted playsinline>
  <source src="..." type="video/mp4">
</video>

If you don't want your video being muted, but still want autoplay, maybe try to remove muted attribute with js: How to unmute html5 video with a muted prop

Try this if your code lies in a form:

Graphics g = this.CreateGraphics();
points = pixels * 72 / g.DpiX;
g.Dispose();

Selenium Web Driver Handling Frames
It is impossible to click iframe directly through XPath since it is an iframe. First we have to switch to the frame and then we can click using xpath.

driver.switchTo().frame() has multiple overloads.

1. driver.switchTo().frame(name_or_id)
   Here your iframe doesn't have id or name, so not for you.

2. driver.switchTo().frame(index)
   This is the last option to choose, because using index is not stable enough as you could imagine. If this is your only iframe in the page, try driver.switchTo().frame(0)

3. driver.switchTo().frame(iframe_element)
   The most common one. You locate your iframe like other elements, then pass it into the method.

driver.switchTo().defaultContent(); [parentFrame, defaultContent, frame]

// Based on index position:
int frameIndex = 0;
List<WebElement> listFrames = driver.findElements(By.tagName("iframe"));
System.out.println("list frames   "+listFrames.size());
driver.switchTo().frame(listFrames.get( frameIndex ));

// XPath|CssPath Element:
WebElement frameCSSPath = driver.findElement(By.cssSelector("iframe[title='Fill Quote']"));
WebElement frameXPath = driver.findElement(By.xpath(".//iframe[1]"));
WebElement frameTag = driver.findElement(By.tagName("iframe"));

driver.switchTo().frame( frameCSSPath ); // frameXPath, frameTag


driver.switchTo().frame("relative=up"); // focus to parent frame.
driver.switchTo().defaultContent(); // move to the most parent or main frame

// For alert's
Alert alert = driver.switchTo().alert(); // Switch to alert pop-up
alert.accept();
alert.dismiss();

XML Test:

<html>
    <IFame id='1'>...       parentFrame() « context remains unchanged. <IFame1>
    |
     -> <IFrame id='2'>...  parentFrame() « Change focus to the parent context. <IFame1>
</html>

</html>
<frameset cols="50%,50%">

                           frame("relative=up") « focus to parent frame. <Fame11>

Starting in Python 3.9, you can use removeprefix:

'Path=helloworld'.removeprefix('Path=')
# 'helloworld'

Thousands of ways to skin this cat. I realize you're asking about between {{}} speifically, but for others that come here, I think it's worth showing some of the other options.

function on your $scope (IMO, this is your best bet in most scenarios):

  app.controller('MyCtrl', function($scope) {
      $scope.foo = 1;

      $scope.showSomething = function(input) {
           return input == 1 ? 'Foo' : 'Bar';
      };
   });

 <span>{{showSomething(foo)}}</span>

ng-show and ng-hide of course:

 <span ng-show="foo == 1">Foo</span><span ng-hide="foo == 1">Bar</span>

ngSwitch

 <div ng-switch on="foo">
   <span ng-switch-when="1">Foo</span>
   <span ng-switch-when="2">Bar</span>
   <span ng-switch-default>What?</span>
 </div>

A custom filter as Bertrand suggested. (this is your best choice if you have to do the same thing over and over)

app.filter('myFilter', function() {
   return function(input) {
     return input == 1 ? 'Foo' : 'Bar';
   }
}

{{foo | myFilter}}

Or A custom directive:

app.directive('myDirective', function() {
   return {
     restrict: 'E',
     replace: true,
     link: function(scope, elem, attrs) {
       scope.$watch(attrs.value, function(v) {
          elem.text(v == 1 ? 'Foo': 'Bar');
       });
     }
   };
});


<my-directive value="foo"></my-directive>

Personally, in most cases I'd go with a function on my scope, it keeps the markup pretty clean, and it's quick and easy to implement. Unless, that is, you're going to be doing the same exact thing over and over again, in which case I'd go with Bertrand's suggestion and create a filter or possibly a directive, depending on the circumstances.

As always, the most important thing is that your solution is easy to maintain, and is hopefully testable. And that is going to depend completely on your specific situation.

you can show the file selection dialog with a onclick function, and if a file is choosen (onchange event) then send the form to upload the file

 <form id='foto' method='post' action='upload' method="POST"  enctype="multipart/form-data" >
  <div style="height:0px;overflow:hidden"> 
  <input type="file" id="fileInput" name="fileInput" onchange="this.form.submit()"/> 
  </div>

  <i class='fa fa-camera' onclick="fileInput.click();"></i>
</form> 

In Android Studio 3:

• Open Device File Explorer (Lower Right of screen).
• Go to data/data/com.yourAppName/shared_prefs.

or use Android Debug Database

The Host property will return the domain name you used when accessing the site. So, in your development environment, since you're requesting

http://localhost:950/m/pages/Searchresults.aspx?search=knife&filter=kitchen

It's returning localhost. You can break apart your URL like so:

Protocol: http
Host: localhost
Port: 950
PathAndQuery: /m/pages/SearchResults.aspx?search=knight&filter=kitchen

Is your BitLocker disk encryption running? In my case, it locked the whole drive of the disk for encryption, and SVN failed with this error.

This is what exactly worked for me:

1. Make sure no other MySQL process is running.To check this do the following:

    a.From the terminal, run this command:
          lsof -i:3306 
      If any PID is returned, kill it using kill -9 PID
    b. Go To System Preferences > MySQL > check if any MySQL instances 
       are running, stop them.
   

2. Start MySQL with the command:

   sudo /usr/local/mysql/bin/mysqld_safe --skip-grant-tables
   

3. The password for every user is stored in the mysql.user table under columns User and authentication_string respectively. We can update the table as:

   UPDATE mysql.user SET authentication_string='your_password' where User='root'
   

You can use Thread.getCurrentThread.getId(), but why would you want to do that when LogRecord objects managed by the logger already have the thread Id. I think you are missing a configuration somewhere that logs the thread Ids for your log messages.

If you want to convert a single VARBINARY value into VARCHAR (STRING) you can do by declaring a variable like this:

DECLARE @var VARBINARY(MAX)
SET @var = 0x21232F297A57A5A743894A0E4A801FC3
SELECT CAST(@var AS VARCHAR(MAX))

If you are trying to select from table column then you can do like this:

SELECT CAST(myBinaryCol AS VARCHAR(MAX))
FROM myTable

For instance, you have the following dictionary:

dict = {'a': 'fire', 'b': 'ice', 'c': 'fire', 'd': 'water'}

And you wanna get it in such an inverted form:

inverted_dict = {'fire': ['a', 'c'], 'ice': ['b'], 'water': ['d']}

First Solution. For inverting key-value pairs in your dictionary use a for-loop approach:

# Use this code to invert dictionaries that have non-unique values

inverted_dict = dict()
for key, value in dict.items():
    inverted_dict.setdefault(value, list()).append(key)

Second Solution. Use a dictionary comprehension approach for inversion:

# Use this code to invert dictionaries that have unique values

inverted_dict = {value: key for key, value in dict.items()}

Third Solution. Use reverting the inversion approach (relies on second solution):

# Use this code to invert dictionaries that have lists of values

dict = {value: key for key in inverted_dict for value in my_map[key]}

The compiler looks for each symbol being used in the current translation unit is previously declared or not in the current unit. It is just a matter of style providing all method signatures at the beginning of a source file while definitions are provided later. The significant use of it is when you use a pointer to a class as member variable of another class.

//foo.h
class bar;    // This is useful
class foo
{
    bar* obj; // Pointer or even a reference.
};

// foo.cpp
#include "bar.h"
#include "foo.h"

So, use forward-declarations in classes when ever possible. If your program just has functions( with ho header files), then providing prototypes at the beginning is just a matter of style. This would be anyhow the case had if the header file was present in a normal program with header that has only functions.

You have mostly the right idea, it's just the sending of the form that is wrong. The form belongs in the body of the request.

req, err := http.NewRequest("POST", url, strings.NewReader(form.Encode()))

use this Reload page

success: function(data){
   if(data.success == true){ // if true (1)
      setTimeout(function(){// wait for 5 secs(2)
           location.reload(); // then reload the page.(3)
      }, 5000); 
   }
}

This should work:

$("#table-filters>ul>li.active").removeClass("active");
//Find all `li`s with class `active`, children of `ul`s, children of `table-filters`

Using @extend is a fine solution, but be aware that the compiled css will break up the class definition. Any classes that extends the same placeholder will be grouped together and the rules that aren't extended in the class will be in a separate definition. If several classes become extended, it can become unruly to look up a selector in the compiled css or the dev tools. Whereas a mixin will duplicate the mixin code and add any additional styles.

You can see the difference between @extend and @mixin in this sassmeister

use rgba (rgb with alpha transparency):

border: 10px solid rgba(0,0,0,0.5); // 0.5 means 50% of opacity

The alpha transparency variate between 0 (0% opacity = 100% transparent) and 1 (100 opacity = 0% transparent)

I have found a way if you know startIndex and endIndex of the elements one need to remove from ArrayList

Let al be the original ArrayList and startIndex,endIndex be start and end index to be removed from the array respectively:

al.subList(startIndex, endIndex + 1).clear();

Primary key is a subset of super key. Which is uniquely define and other field are depend on it. In a table their can be just one primary key and rest sub set are candidate key or alternate keys.

I solve this by adding code into manifest:

<activity android:name=".Login"
        android:fitsSystemWindows="true"
        android:windowSoftInputMode="stateHidden|adjustPan"
</activity>

This will eliminate the error and is type safe:

this.DNATranscriber[character as keyof typeof DNATranscriber]

You can also use strdup:

char* p = strdup("abc");

There are five methods to choose from:

• setItem(): Add key and value to localStorage
• getItem(): Retrieve a value by the key from localStorage
• removeItem(): Remove an item by key from localStorage
• clear(): Clear all localStorage
• key(): Passed a number to retrieve nth key of a localStorage

You can use clear(), this method when invoked clears the entire storage of all records for that domain. It does not receive any parameters.

window.localStorage.clear();

try this code below it works fine with me.

example below is getting the host and redirecting to another page.

var host = $(location).attr('host');
window.location.replace("http://"+host+"/TEST_PROJECT/INDEXINGPAGE");

Focusing should also be checked in onBackPressed

    @Override
    public void onBackPressed() {
        if (mWebview.isFocused() && mWebview.canGoBack()) {
            mWebview.goBack();       
        } else {
            super.onBackPressed();
            finish();
        }
    }

Well, data.str().c_str() yields a char const* but your function Printfunc() wants to have char*s. Based on the name, it doesn't change the arguments but merely prints them and/or uses them to name a file, in which case you should probably fix your declaration to be

void Printfunc(int a, char const* loc, char const* stream)

The alternative might be to turn the char const* into a char* but fixing the declaration is preferable:

Printfunc(num, addr, const_cast<char*>(data.str().c_str()));

Off the top of my head:

$('#content').height(
    $(window).height() - $('#header').height() - $('#footer').height()
);

Is that what you mean?

I think you are looking for this function:

http://doc.qt.io/qt-5/qdatetime.html#toTime_t

uint QDateTime::toTime_t () const

Returns the datetime as the number of seconds that have passed since 1970-01-01T00:00:00, > Coordinated Universal Time (Qt::UTC).

On systems that do not support time zones, this function will behave as if local time were Qt::UTC.

See also setTime_t().

Here's a 100% pure Bash function that does the job:

join() {
    # $1 is return variable name
    # $2 is sep
    # $3... are the elements to join
    local retname=$1 sep=$2 ret=$3
    shift 3 || shift $(($#))
    printf -v "$retname" "%s" "$ret${@/#/$sep}"
}

Look:

$ a=( one two "three three" four five )
$ join joineda " and " "${a[@]}"
$ echo "$joineda"
one and two and three three and four and five
$ join joinedb randomsep "only one element"
$ echo "$joinedb"
only one element
$ join joinedc randomsep
$ echo "$joinedc"

$ a=( $' stuff with\nnewlines\n' $'and trailing newlines\n\n' )
$ join joineda $'a sep with\nnewlines\n' "${a[@]}"
$ echo "$joineda"
 stuff with
newlines
a sep with
newlines
and trailing newlines


$

This preserves even the trailing newlines, and doesn't need a subshell to get the result of the function. If you don't like the printf -v (why wouldn't you like it?) and passing a variable name, you can of course use a global variable for the returned string:

join() {
    # $1 is sep
    # $2... are the elements to join
    # return is in global variable join_ret
    local sep=$1 IFS=
    join_ret=$2
    shift 2 || shift $(($#))
    join_ret+="${*/#/$sep}"
}

n stable wouldn't do the trick for me. On the other hand,

nvm install stable

That actually got me to last nodejs version. Apparently n stable won't get pass v0.12.14 for me. I really don't know why.

Note: nvm is Node Version Manager, you can install it from its github page. Thanks @isaiah for noting that nvm is not a known command.

Here's a quick jQuery plugin to map the built in browser functionality nicely:

$.fn.ensureVisible = function () { $(this).each(function () { $(this)[0].scrollIntoView(); }); };

$('.my-elements').ensureVisible();

WSDL: Stands for Web Service Description Language

In SOAP(simple object access protocol), when you use web service and add a web service to your project, your client application(s) doesn't know about web service Functions. Nowadays it's somehow old-fashion and for each kind of different client you have to implement different WSDL files. For example you cannot use same file for .Net and php client. The WSDL file has some descriptions about web service functions. The type of this file is XML. SOAP is an alternative for REST.

REST: Stands for Representational State Transfer

It is another kind of API service, it is really easy to use for clients. They do not need to have special file extension like WSDL files. The CRUD operation can be implemented by different HTTP Verbs(GET for Reading, POST for Creation, PUT or PATCH for Updating and DELETE for Deleting the desired document) , They are based on HTTP protocol and most of times the response is in JSON or XML format. On the other hand the client application have to exactly call the related HTTP Verb via exact parameters names and types. Due to not having special file for definition, like WSDL, it is a manually job using the endpoint. But it is not a big deal because now we have a lot of plugins for different IDEs to generating the client-side implementation.

SOA: Stands for Service Oriented Architecture

Includes all of the programming with web services concepts and architecture. Imagine that you want to implement a large-scale application. One practice can be having some different services, called micro-services and the whole application mechanism would be calling needed web service at the right time. Both REST and SOAP web services are kind of SOA.

JSON: Stands for javascript Object Notation

when you serialize an object for javascript the type of object format is JSON. imagine that you have the human class :

class Human{
 string Name;
 string Family;
 int Age;
}

and you have some instances from this class :

Human h1 = new Human(){
  Name='Saman',
  Family='Gholami',
  Age=26
}

when you serialize the h1 object to JSON the result is :

  [h1:{Name:'saman',Family:'Gholami',Age:'26'}, ...]

javascript can evaluate this format by eval() function and make an associative array from this JSON string. This one is different concept in comparison to other concepts I described formerly.

Am using Mountain Lion. What I did was Look for /usr/local and Get Info. On it there is Sharing and Permissions. Make sure that its only the user and Admin are the only ones who have read and write permissions. Anyone else should have read access only. That sorted my problem.

Its normally helpful is your Run disk utilities and repair permissions too.

As mentioned in all other answers, the keyword continue will skip to the end of the current iteration.

Additionally you can label your loop starts and then use continue [labelname]; or break [labelname]; to control what's going on in nested loops:

loop1: for (int i = 1; i < 10; i++) {
    loop2: for (int j = 1; j < 10; j++) {
        if (i + j == 10)
            continue loop1;

        System.out.print(j);
    }
    System.out.println();
}

There are two methods you can sometimes use to determine if a recipient actually exists:

1. You can connect to the server, and issue a VRFY command. Very few servers support this command, but it is intended for exactly this. If the server responds with a 2.0.0 DSN, the user exists.

   VRFY user
   

2. You can issue a RCPT, and see if the mail is rejected.

   MAIL FROM:<>
   RCPT TO:<user@domain>
   

If the user doesn't exist, you'll get a 5.1.1 DSN. However, just because the email is not rejected, does not mean the user exists. Some server will silently discard requests like this to prevent enumeration of their users. Other servers cannot verify the user and have to accept the message regardless.

There is also an antispam technique called greylisting, which will cause the server to reject the address initially, expecting a real SMTP server would attempt a re-delivery some time later. This will mess up attempts to validate the address.

Honestly, if you're attempting to validate an address the best approach is to use a simple regex to block obviously invalid addresses, and then send an actual email with a link back to your system that will validate the email was received. This also ensures that they user entered their actual email, not a slight typo that happens to belong to somebody else.

The easiest way is to create C# Process and launch external tool to print your PDF file

private static void ExecuteRawFilePrinter() {
    Process process = new Process();
    process.StartInfo.FileName = "c:\\Program Files (x86)\\RawFilePrinter\\RawFilePrinter.exe";
    process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
    process.StartInfo.Arguments = string.Format("-p \"c:\\Users\\Me\\Desktop\\mypdffile.pdf\" \"gdn02ptr006\"");
    process.Start();
    process.WaitForExit();
}

Code above launches RawFilePrinter.exe (similar to 2Printer.exe), but with better support. It is not free, but by making donation allow you to use it everywhere and redistribute with your application. Latest version to download: http://bigdotsoftware.pl/rawfileprinter

I couldn't get .destroy() to work either so this is what I'm doing. The chart_parent div is where I want the canvas to show up. I need the canvas to resize each time, so this answer is an extension of the above one.

You could give your hidden field an id:

<input type="hidden" id="myField" value="" />

and then when you want to assign its value:

document.getElementById('myField').value = product(2, 3);

Make sure that you are performing this assignment after the DOM has been fully loaded, for example in the window.load event.

Read this thread R - boolean operators && and ||.

Basically, the & is vectorized, i.e. it acts on each element of the comparison returning a logical array with the same dimension as the input. && is not, returning a single logical.

I update mac to Sierra , 10.12.3

My wget stop working.

When I tried to install by typing

brew install wget --with-libressl

I got the following warning

Warning: wget-1.19.1 already installed, it's just not linked.

Then tried to unsintall by typing

brew uninstall wget --with-libressl

Then I reinstalled by typing

brew install wget --with-libressl

Finally I got it worked.Thank God!

Verify the length property of the array to be greater than 0:

<p ng-if="post.capabilities.items.length > 0">
   <strong>Topics</strong>: 
   <span ng-repeat="topic in post.capabilities.items">
     {{topic.name}}
   </span>
</p>

Arrays (objects) in JavaScript are truthy values, so your initial verification <p ng-if="post.capabilities.items"> evaluates always to true, even if the array is empty.

Adding to Alex's answer and simplifying it:

Objects are more strict with their use and hence gives the programmer more compile time "evaluation" power and hence in a lot of cases provide more "checking capability" and coould prevent any leaks, whereas any is a more generic term and a lot of compile time checks might hence be ignored.

Here's a trick to easily check if the schema already exists, and then create it, in it's own batch, to avoid the error message of trying to create a schema when it's not the only command in a batch.

IF NOT EXISTS (SELECT schema_name 
    FROM information_schema.schemata 
    WHERE schema_name = 'newSchemaName' )
BEGIN
    EXEC sp_executesql N'CREATE SCHEMA NewSchemaName;';
END

Convert the Dictionary to JSON string first with Newtonsoft.

var json = JsonConvert.SerializeObject(advancedSettingsDictionary, Newtonsoft.Json.Formatting.Indented);

Then deserialize the JSON string to your object

var myobject = JsonConvert.DeserializeObject<AOCAdvancedSettings>(json);

Try this

static DataTable ConvertToDatatable(List<Item> list)
{
    DataTable dt = new DataTable();

    dt.Columns.Add("Name");
    dt.Columns.Add("Price");
    dt.Columns.Add("URL");
    foreach (var item in list)
    {
        var row = dt.NewRow();

        row["Name"] = item.Name;
        row["Price"] = Convert.ToString(item.Price);
        row["URL"] = item.URL;

        dt.Rows.Add(row);
    }

    return dt;
}

In case someone is feverishly googling to solve the bouncing images carousel thing, this helped me:

.fusion-carousel .fusion-carousel-item img {
    width: auto;
    height: 146px;
    max-height: 146px;
    object-fit: contain;
}

If you want the object_name prefixed to any ID you should call form helpers on the form object:

- form_for(@message) do |f|
  = f.label :email

This also makes sure any submitted data is stored in memory should there be any validation errors etc.

If you can't call the form helper method on the form object, for example if you're using a tag helper (radio_button_tag etc.) you can interpolate the name using:

= radio_button_tag "#{f.object_name}[email]", @message.email

In this case you'd need to specify the value manually to preserve any submissions.

As an add-on to the other answers, here's how I'd explain it to a layman:

Your source code is like the blueprint of a ship. It defines how the ship should be made.

If you hand off your blueprint to the shipyard, and they find a defect while building the ship, they'll stop building and report it to you immediately, before the ship has ever left the drydock or touched water. This is a compile-time error. The ship was never even actually floating or using its engines. The error was found because it prevented the ship even being made.

When your code compiles, it's like the ship being completed. Built and ready to go. When you execute your code, that's like launching the ship on a voyage. The passengers are boarded, the engines are running and the hull is on the water, so this is runtime. If your ship has a fatal flaw that sinks it on its maiden voyage (or maybe some voyage after for extra headaches) then it suffered a runtime error.

You mention the certificate is self-signed (by you)? Then you have two choices:

• add the certificate to your trust store (fetching cacert.pem from cURL website won't do anything, since it's self-signed)
• don't bother verifying the certificate: you trust yourself, don't you?

Here's a list of SSL context options in PHP: https://secure.php.net/manual/en/context.ssl.php

Set allow_self_signed if you import your certificate into your trust store, or set verify_peer to false to skip verification.

The reason why we trust a specific certificate is because we trust its issuer. Since your certificate is self-signed, no client will trust the certificate as the signer (you) is not trusted. If you created your own CA when signing the certificate, you can add the CA to your trust store. If your certificate doesn't contain any CA, then you can't expect anyone to connect to your server.

I had the same issue, but it was happening because my file was called "geo_data.csv.csv" - new laptop wasn't showing file extensions, so the name issue was invisible in Windows Explorer. Very silly, I know, but if this solution doesn't work for you, try that :-)

Yep, moment.js is pretty good for this:

var moment = require('moment');
var startDate = new Date();
var endDate = new Date();
endDate.setDate(endDate.getFullYear() + 5); // Add 5 years to second date
console.log(moment.duration(endDate - startDate).years()); // This should returns 5

1) Upgrade using windows update or using "media creation tool" http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install

• if you are using "media creation tool" select "Upgrade this PC now"

When Windows 10 installed check that it is activated.

2) Now as you have activated Windows 10 using "media creation tool" http://windows.microsoft.com/en-us/windows-10/media-creation-tool-install select second option "Create installation media for another PC" here you can select Windows version and its language. Make sure that Windows version is also "Single Language"

3) Boot from you device, USB in my case and install clean Windows in English or any other language you selected.

super is used to access methods of the base class while this is used to access methods of the current class.

Extending the notion, if you write super(), it refers to constructor of the base class, and if you write this(), it refers to the constructor of the very class where you are writing this code.

Would be safer to do this.

@{ Response.Redirect("~/Account/LogIn?returnUrl=Products");}

So the controller for that action runs as well, to populate any model the view needs.

Redirect from a view to another view

Although as @Satpal mentioned, I do recommend you do the redirecting on your controller.

I also found that in some cases the reason for 502/400 in case of many headers could be because of a large number of headers without regard to size. from the docs

tune.http.maxhdr Sets the maximum number of headers in a request. When a request comes with a number of headers greater than this value (including the first line), it is rejected with a "400 Bad Request" status code. Similarly, too large responses are blocked with "502 Bad Gateway". The default value is 101, which is enough for all usages, considering that the widely deployed Apache server uses the same limit. It can be useful to push this limit further to temporarily allow a buggy application to work by the time it gets fixed. Keep in mind that each new header consumes 32bits of memory for each session, so don't push this limit too high.

I have found that using cabs(double), cabsf(float), cabsl(long double), __cabsf(float), __cabs(double), __cabsf(long double) is the solution

I don't think jQuery itself includes datetimepicker. You must use jQuery UI instead (src="jquery.ui").

All required parameters must be placed before any default arguments. Simply because they are mandatory, whereas default arguments are not. Syntactically, it would be impossible for the interpreter to decide which values match which arguments if mixed modes were allowed. A SyntaxError is raised if the arguments are not given in the correct order:

Let us take a look at keyword arguments, using your function.

def fun1(a="who is you", b="True", x, y):
...     print a,b,x,y

Suppose its allowed to declare function as above, Then with the above declarations, we can make the following (regular) positional or keyword argument calls:

func1("ok a", "ok b", 1)  # Is 1 assigned to x or ?
func1(1)                  # Is 1 assigned to a or ?
func1(1, 2)               # ?

How you will suggest the assignment of variables in the function call, how default arguments are going to be used along with keyword arguments.

>>> def fun1(x, y, a="who is you", b="True"):
...     print a,b,x,y
... 

Reference O'Reilly - Core-Python
Where as this function make use of the default arguments syntactically correct for above function calls. Keyword arguments calling prove useful for being able to provide for out-of-order positional arguments, but, coupled with default arguments, they can also be used to "skip over" missing arguments as well.

Port:

A port can refer to a physical connection point for peripheral devices such as serial, parallel, and USB ports. The term port also refers to certain Ethernet connection points, s uch as those on a hub, switch, or router.

Socket:

A socket represents a single connection between two network applications. These two applications nominally run on different computers, but sockets can also be used for interprocess communication on a single computer. Applications can create multiple sockets for communicating with each other. Sockets are bidirectional, meaning that either side of the connection is capable of both sending and receiving data.

You need to use cp -t /home/shantanu/tosend in order to tell it that the argument is the target directory and not a source. You can then change it to -exec ... + in order to get cp to copy as many files as possible at once.

maven should be on the system's PATH if you wish to execute it from any place. add %M2_HOME%\bin to the PATH

You can get your package name like so:

$ /path/to/adb shell 'pm list packages -f myapp'

adb sync notes: adb sync [ <directory> ]
  <localdir> can be interpreted in several ways:

  - If <directory> is not specified, /system, /vendor (if present), /oem (if present) and /data partitions will be updated.

  - If it is "system", "vendor", "oem" or "data", only the corresponding partition
    is updated.

  ANDROID_SERIAL               - The serial number to connect to. -s takes priority over this if given.
  ANDROID_LOG_TAGS             - When used with the logcat option, only these debug tags are printed.

You can do that in your app.config. like that:

maxReceivedMessageSize="2147483647" 

(The max value is Int32.MaxValue )

Or in Code:

WSHttpBinding binding = new WSHttpBinding();
binding.Name = "MyBinding";
binding.MaxReceivedMessageSize = Int32.MaxValue;

Note:

If your service is open to the Wide world, think about security when you increase this value.

If you have a one to many relationship in your query, duplicate rows may occurs on one side.

Suppose the following

TABLE TEAM
ID       TEAM_NAME
0        BULLS
1        LAKERS


TABLE PLAYER
ID       TEAM_ID     PLAYER_NAME
0        0           JORDAN
1        0           PIPPEN

And you execute a query like

SELECT 
    TEAM.TEAM_NAME, 
    PLAYER.PLAYER_NAME 
FROM TEAM
INNER JOIN PLAYER

You will get

TEAM_NAME   PLAYER_NAME
BULLS       JORDAN
BULLS       PIPPEN

So you will have duplicate TEAM NAME. Even using DISTINCT clause, your result set will contain duplicate TEAM NAME

So if you do not want duplicate TEAM_NAME in your query, do the following

SELECT ID, TEAM_NAME FROM TEAM

And for each team ID encountered executes

SELECT PLAYER_NAME FROM PLAYER WHERE TEAM_ID = <PUT_TEAM_ID_RIGHT_HERE>

So this way you will not get duplicates references on one side

regards,

If you do not want to depend on throwing exception (which you probably should not) you can try this:

public static <T> T cast(Object o, Class<T> clazz) {
    return clazz.isInstance(o) ? clazz.cast(o) : null;
}

The second parameter of findBy is for ORDER.

$ens = $em->getRepository('AcmeBinBundle:Marks')
          ->findBy(
             array('type'=> 'C12'), 
             array('id' => 'ASC')
           );

I was getting this error after adding the include files and linking the library. It was because the lib was built with non-unicode and my application was unicode. Matching them fixed it.

You can create an XML file in the drawable folder. Call it, for example, shape.xml

In shape.xml:

<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"   >

    <solid
        android:color="#888888" >
    </solid>

    <stroke
        android:width="2dp"
        android:color="#C4CDE0" >
    </stroke>

    <padding
        android:left="5dp"
        android:top="5dp"
        android:right="5dp"
        android:bottom="5dp"    >
    </padding>

    <corners
        android:radius="11dp"   >
    </corners>

</shape>

The <corner> tag is for your specific question.

Make changes as required.

And in your whatever_layout_name.xml:

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:layout_margin="5dp"
    android:background="@drawable/shape"    >
</LinearLayout>

This is what I usually do in my apps. Hope this helps....

Note that Python3 does not read the html code as a string but as a bytearray, so you need to convert it to one with decode.

import urllib.request

fp = urllib.request.urlopen("http://www.python.org")
mybytes = fp.read()

mystr = mybytes.decode("utf8")
fp.close()

print(mystr)

Josh Bloch favors your approach:

The reason that I favor the instanceof approach is that when you use the getClass approach, you have the restriction that objects are only equal to other objects of the same class, the same run time type. If you extend a class and add a couple of innocuous methods to it, then check to see whether some object of the subclass is equal to an object of the super class, even if the objects are equal in all important aspects, you will get the surprising answer that they aren't equal. In fact, this violates a strict interpretation of the Liskov substitution principle, and can lead to very surprising behavior. In Java, it's particularly important because most of the collections (HashTable, etc.) are based on the equals method. If you put a member of the super class in a hash table as the key and then look it up using a subclass instance, you won't find it, because they are not equal.

See also this SO answer.

Effective Java chapter 3 also covers this.

It is called the Conditional Operator (which is a ternary operator).

It has the form of: condition ? value-if-true : value-if-false
Think of the ? as "then" and : as "else".

Your code is equivalent to

if (max != 0)
  hsb.s = 255 * delta / max;
else
  hsb.s = 0;

Bash is primarily a batch / shell scripting language with far less support for various data types and all sorts of quirks around control structures -- not to mention compatibility issues.

Which is faster? Neither, because you are not comparing apples to apples here. If you had to sort an ascii text file and you were using tools like zcat, sort, uniq, and sed then you will smoke Python performance wise.

However, if you need a proper programming environment that supports floating point and various control flow, then Python wins hands down. If you wrote say a recursive algorithm in Bash and Python, the Python version will win in an order of magnitude or more.

One gotcha I have found is where two objects contain references to each other (one example being a parent/child relationship with a convenience method on the parent to get all children).
These sorts of things are fairly common when doing Hibernate mappings for example.

If you include both ends of the relationship in your hashCode or equals tests it's possible to get into a recursive loop which ends in a StackOverflowException.
The simplest solution is to not include the getChildren collection in the methods.

Wouldn't it be easier to test the cube roots? Start with 20 (20**3 = 8000) and go up to 30 (30**3 = 27000). Then you have to test fewer than 10 integers.

for i in range(20, 30):
    print("Trying {0}".format(i))
    if i ** 3 > 12000:
        print("Maximum integral cube root less than 12000: {0}".format(i - 1))
        break

In case someone else ends up here struggling to customize admin form Many2Many saving behaviour, you can't call self.instance.my_m2m.add(obj) in your ModelForm.save override, as ModelForm.save later populates your m2m from self.cleaned_data['my_m2m'] which overwrites your changes. Instead call:

my_m2ms = list(self.cleaned_data['my_m2ms'])
my_m2ms.extend(my_custom_new_m2ms)
self.cleaned_data['my_m2ms'] = my_m2ms

(It is fine to convert the incoming QuerySet to a list - the ManyToManyField does that anyway.)

Use like this. Here is the online compilation of the code. Take a look http://ideone.com/MJJwtc

public static void swap(List list,
                        int i,
                        int j)

Swaps the elements at the specified positions in the specified list. (If the specified positions are equal, invoking this method leaves the list unchanged.)

Parameters: list - The list in which to swap elements. i - the index of one element to be swapped. j - the index of the other element to be swapped.

You're probably not accessing it correctly. You can output it directly or cast it as a string. (in this example, the casting is superfluous, as echo automatically does it anyway)

$content = simplexml_load_string(
    '<content><![CDATA[Hello, world!]]></content>'
);
echo (string) $content;

// or with parent element:

$foo = simplexml_load_string(
    '<foo><content><![CDATA[Hello, world!]]></content></foo>'
);
echo (string) $foo->content;

You might have better luck with LIBXML_NOCDATA:

$content = simplexml_load_string(
    '<content><![CDATA[Hello, world!]]></content>'
    , null
    , LIBXML_NOCDATA
);

Using a nested .each() means that your inner loop is doing one td at a time, so you can't set the productId and product and quantity all in the inner loop.

Also using function(key, val) and then val[key].innerHTML isn't right: the .each() method passes the index (an integer) and the actual element, so you'd use function(i, element) and then element.innerHTML. Though jQuery also sets this to the element, so you can just say this.innerHTML.

Anyway, here's a way to get it to work:

    table.find('tr').each(function (i, el) {
        var $tds = $(this).find('td'),
            productId = $tds.eq(0).text(),
            product = $tds.eq(1).text(),
            Quantity = $tds.eq(2).text();
        // do something with productId, product, Quantity
    });

You've got the right idea, so here's how to go ahead: the onclick handlers run on the client side, in the browser, so you cannot call a PHP function directly. Instead, you need to add a JavaScript function that (as you mentioned) uses AJAX to call a PHP script and retrieve the data. Using jQuery, you can do something like this:

<script type="text/javascript">
function recp(id) {
  $('#myStyle').load('data.php?id=' + id);
}
</script>

<a href="#" onClick="recp('1')" > One   </a>
<a href="#" onClick="recp('2')" > Two   </a>
<a href="#" onClick="recp('3')" > Three </a>

<div id='myStyle'>
</div>

Then you put your PHP code into a separate file: (I've called it data.php in the above example)

<?php
  require ('myConnect.php');     
  $id = $_GET['id'];
  $results = mysql_query("SELECT para FROM content WHERE  para_ID='$id'");   
  if( mysql_num_rows($results) > 0 )
  {
   $row = mysql_fetch_array( $results );
   echo $row['para'];
  }
?>

You can use .sortBy, it will always return an ascending list:

_.sortBy([2, 3, 1], function(num) {
    return num;
}); // [1, 2, 3]

But you can use the .reverse method to get it descending:

var array = _.sortBy([2, 3, 1], function(num) {
    return num;
});

console.log(array); // [1, 2, 3]
console.log(array.reverse()); // [3, 2, 1]

Or when dealing with numbers add a negative sign to the return to descend the list:

_.sortBy([-3, -2, 2, 3, 1, 0, -1], function(num) {
    return -num;
}); // [3, 2, 1, 0, -1, -2, -3]

Under the hood .sortBy uses the built in .sort([handler]):

// Default is ascending:
[2, 3, 1].sort(); // [1, 2, 3]

// But can be descending if you provide a sort handler:
[2, 3, 1].sort(function(a, b) {
    // a = current item in array
    // b = next item in array
    return b - a;
});

Simple Solution. No Jquery

While writing this question, I discovered the answer. Installing a CA from Safari no longer automatically trusts it. I had to manually trust it from the Certificate Trust Settings panel (also mentioned in this question).

I debated canceling the question, but I thought it might be helpful to have some of the relevant code and log details someone might be looking for. Also, I never encountered the issue until iOS 11. I even went back and reconfirmed that it automatically works up through iOS 10.

I've never needed to touch that settings panel before, because any installed certificates were automatically trusted. Maybe it will change by the time iOS 11 ships, but I doubt it. Hopefully this helps save someone the time I wasted.

If anyone knows why this behaves differently for some people on different versions of iOS, I'd love to know in comments.

Update 1: Checking out the first iOS 12 beta, it looks like things remain the same. This question/answer/comments are still relevant on iOS 12.

Update 2: Same solution seems to be needed on iOS 13 beta builds as well.

Hope this helps someone, worked for me.

You need pow(); function from math.h header.
syntax

#include <math.h>
double pow(double x, double y);
float powf(float x, float y);
long double powl(long double x, long double y);

Here x is base and y is exponent. result is x^y.

usage

pow(2,4);  

result is 2^4 = 16. //this is math notation only   
// In c ^ is a bitwise operator

And make sure you include math.h to avoid warning ("incompatible implicit declaration of built in function 'pow' ").

Link math library by using -lm while compiling. This is dependent on Your environment.
For example if you use Windows it's not required to do so, but it is in UNIX based systems.

This is because you are referring to property of controller named HttpContext. To access the current context use full class name:

System.Web.HttpContext.Current

However this is highly not recommended to access context like this in ASP.NET MVC, so yes, you can think of System.Web.HttpContext.Current as being deprecated inside ASP.NET MVC. The correct way to access current context is

this.ControllerContext.HttpContext

or if you are inside a Controller, just use member

this.HttpContext

If you are using Query builder then you may use a blow

DB::table(Newsletter Subscription)
->select('*')
->whereIn('id', $send_users_list)
->get()

If you are working with Eloquent then you can use as below

$sendUsersList = Newsletter Subscription:: select ('*')
                ->whereIn('id', $send_users_list)
                ->get();

Normally you can use None, but you can also use objc.NULL, e.g.

import objc
val = objc.NULL

Especially useful when working with C code in Python.

Also see: Python objc.NULL Examples

I had the same question, and have spent all day trying out different packages.

I had originally used matlibplot: and was not happy with either mapping categories to predefined colors; or grouping/aggregating then iterating through the groups (and still having to map colors). I just felt it was poor package implementation.

Seaborn wouldn't work on my case, and Altair ONLY works inside of a Jupyter Notebook.

The best solution for me was PlotNine, which "is an implementation of a grammar of graphics in Python, and based on ggplot2".

Below is the plotnine code to replicate your R example in Python:

from plotnine import *
from plotnine.data import diamonds

g = ggplot(diamonds, aes(x='carat', y='price', color='color')) + geom_point(stat='summary')
print(g)

So clean and simple :)

You should use new when you wish an object to remain in existence until you delete it. If you do not use new then the object will be destroyed when it goes out of scope. Some examples of this are:

void foo()
{
  Point p = Point(0,0);
} // p is now destroyed.

for (...)
{
  Point p = Point(0,0);
} // p is destroyed after each loop

Some people will say that the use of new decides whether your object is on the heap or the stack, but that is only true of variables declared within functions.

In the example below the location of 'p' will be where its containing object, Foo, is allocated. I prefer to call this 'in-place' allocation.

class Foo
{

  Point p;
}; // p will be automatically destroyed when foo is.

Allocating (and freeing) objects with the use of new is far more expensive than if they are allocated in-place so its use should be restricted to where necessary.

A second example of when to allocate via new is for arrays. You cannot* change the size of an in-place or stack array at run-time so where you need an array of undetermined size it must be allocated via new.

E.g.

void foo(int size)
{
   Point* pointArray = new Point[size];
   ...
   delete [] pointArray;
}

(*pre-emptive nitpicking - yes, there are extensions that allow variable sized stack allocations).

Please check if your code doesnt consist of two module projects that have the same classes names and packages definition. For example this could happen if someone uses copy-paste to create new implementation of interface based on previous implementation.

If we have the hash

hash = {"a" : "b", "c": "d"};

we can get the length using the length of the keys which is the length of the hash:

keys(hash).length

If the memory of the Mat mat is continuous (all its data is continuous), you can directly get its data to a 1D array:

std::vector<uchar> array(mat.rows*mat.cols*mat.channels());
if (mat.isContinuous())
    array = mat.data;

Otherwise, you have to get its data row by row, e.g. to a 2D array:

uchar **array = new uchar*[mat.rows];
for (int i=0; i<mat.rows; ++i)
    array[i] = new uchar[mat.cols*mat.channels()];

for (int i=0; i<mat.rows; ++i)
    array[i] = mat.ptr<uchar>(i);

UPDATE: It will be easier if you're using std::vector, where you can do like this:

std::vector<uchar> array;
if (mat.isContinuous()) {
  // array.assign(mat.datastart, mat.dataend); // <- has problems for sub-matrix like mat = big_mat.row(i)
  array.assign(mat.data, mat.data + mat.total()*mat.channels());
} else {
  for (int i = 0; i < mat.rows; ++i) {
    array.insert(array.end(), mat.ptr<uchar>(i), mat.ptr<uchar>(i)+mat.cols*mat.channels());
  }
}

p.s.: For cv::Mats of other types, like CV_32F, you should do like this:

std::vector<float> array;
if (mat.isContinuous()) {
  // array.assign((float*)mat.datastart, (float*)mat.dataend); // <- has problems for sub-matrix like mat = big_mat.row(i)
  array.assign((float*)mat.data, (float*)mat.data + mat.total()*mat.channels());
} else {
  for (int i = 0; i < mat.rows; ++i) {
    array.insert(array.end(), mat.ptr<float>(i), mat.ptr<float>(i)+mat.cols*mat.channels());
  }
}

UPDATE2: For OpenCV Mat data continuity, it can be summarized as follows:

• Matrices created by imread(), clone(), or a constructor will always be continuous.
• The only time a matrix will not be continuous is when it borrows data (except the data borrowed is continuous in the big matrix, e.g. 1. single row; 2. multiple rows with full original width) from an existing matrix (i.e. created out of an ROI of a big mat).

Please check out this code snippet for demonstration.

Yet another way to get your public IP address is to use OpenDNS's resolve1.opendns.com server with myip.opendns.com as the request.

On the command line this is:

  nslookup myip.opendns.com resolver1.opendns.com

Or in C# using the DNSClient nuget:

  var lookup = new LookupClient(new IPAddress(new byte[] { 208, 67, 222, 222 }));
  var result = lookup.Query("myip.opendns.com", QueryType.ANY);

This is a bit cleaner than hitting http endpoints and parsing responses.

I tried all the solutions mentioned above, then did not work. I have 3 tables one below the other. The last one over flowed. I fixed it using:

/* Grid Definition */
table {
    word-break: break-word;
}

For IE11 in edge mode, you need to set this to word-break:break-all

This is because strings are immutable in Python.

Which means that X.replace("hello","goodbye") returns a copy of X with replacements made. Because of that you need replace this line:

X.replace("hello", "goodbye")

with this line:

X = X.replace("hello", "goodbye")

More broadly, this is true for all Python string methods that change a string's content "in-place", e.g. replace,strip,translate,lower/upper,join,...

You must assign their output to something if you want to use it and not throw it away, e.g.

X  = X.strip(' \t')
X2 = X.translate(...)
Y  = X.lower()
Z  = X.upper()
A  = X.join(':')
B  = X.capitalize()
C  = X.casefold()

and so on.

Brendan is correct. You can edit the Select command to edit a filtered list of records. For instance "WHERE dept_no = 200".

<android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"

            app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

Another easy way is to use:

mysqladmin debug 

This dumps a lot of information (including locks) to the error log.

For relative imports see the documentation. A relative import is when you import from a module relative to that module's location, instead of absolutely from sys.path.

As for import *, Python 2 allowed star imports within functions, for instance:

>>> def f():
...     from math import *
...     print sqrt

A warning is issued for this in Python 2 (at least recent versions). In Python 3 it is no longer allowed and you can only do star imports at the top level of a module (not inside functions or classes).

Check the settings.gradle file. The modules which are included may be missing or in another directory. For instance, with below line in settings.gradle, gradle searches common-lib module inside your project directory:

include ':common-lib'

If it is missing, you can find and copy this module into your project or reference its path in settings.gradle file:

include ':common-lib'
project(':common-lib').projectDir = new File('<path to your module i.e. C://Libraries/common-lib>') // 

If you're using IntelliJ 13 with SVN 1.8, you have to install SVN command line client. Please see more information here:

Unlike its earlier versions, Subversion 1.8 support uses the native command line client instead of SVNKit to run commands. This approach is more flexible and makes the support of upcoming versions much easier. Now, IntelliJ IDEA offers different integration options for each specific Subversion:

1.6 – SVNKit only

1.7 – SVNKit and command line client

1.8 – Command line client only

If you want to update data you should use UPDATE command instead of INSERT

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

Manipulating an Access database from Java without ODBC

control + '~' will work for toggling between the two. and '`' is just above the tab button. This shortcut only works in mac.

Add this class in .css class

.scrol  { 
font: bold 14px Arial; 
border:1px solid black; 
width:100% ; 
color:#616D7E; 
height:20px; 
overflow:scroll; 
overflow-y:scroll;
overflow-x:hidden;
}

and use the class in div. like here.

<div> <p class = "scrol" id = "title">-</p></div>

I have attached image , you see the out put of the above code

$.each(obj, function(index, value) {
    $('#looking_for_job_titles').tagsinput('add', value);
    console.log(value);
});

Create a new div element for your element to center, then add a class specifically for centering that element like this

<div id="myNewElement">
    <div class="centered">
        <input type="button" value="My Centered Button"/>
    </div>
</div>

Css

.centered{
    text-align:center;
}

Try to code below,

String[][] shades = new String[4][3];
for(int i = 0; i < 4; i++)
{
  for(int y = 0; y < 3; y++)
  {
    shades[i][y] = value;
  }
}

There's no reliable way to detect first run, as the shared preferences way is not always safe, the user can delete the shared preferences data from the settings! a better way is to use the answers here Is there a unique Android device ID? to get the device's unique ID and store it somewhere in your server, so whenever the user launches the app you request the server and check if it's there in your database or it is new.

In My case @uncaught_exceptions's answer didn't work, I had to use List.class instead of java.lang.reflect.Type:

String jsonDuplicatedItems = request.getSession().getAttribute("jsonDuplicatedItems").toString();
List<Map.Entry<Product, Integer>> entries = gson.fromJson(jsonDuplicatedItems, List.class);

The main utility of a workspace (and maybe the only one) is to allow to add multiple independent folders that compounds a project. For example:

- WorkspaceProjectX  
-- ApiFolder   (maybe /usr/share/www/api)  
-- DocsFolder  (maybe /home/user/projx/html/docs)  
-- WebFolder   (maybe /usr/share/www/web)

So you can group those in a work space for a specific project instead of have to open multiple folders windows.

The jQuery code to grab the data and display it on my webpage:

$(document).ready(function() {
var items = [];

$.getJSON('labOrders.json', function(json) {
  $.each(json.medications, function(index, orders) {
    $.each(this, function() {
        $.each(this, function() {
            items.push('<div class="row">'+this.name+"\t"+this.strength+"\t"+this.dose+"\t"+this.route+"\t"+this.sig+"\t"+this.pillCount+"\t"+this.refills+'</div>'+"\n");
        });
    });
  });

  $('<div>', {
    "class":'loaded',
    html:items.join('')
  }).appendTo("body");

});

});

Just try below a simple solution:

JsonObject body=new JsonObject();
body.add("orders", (JsonElement) orders);

whenever my JSON request is like:

{
      "role": "RT",
      "orders": [
        {
          "order_id": "ORDER201908aPq9Gs",
          "cart_id": 164444,
          "affiliate_id": 0,
          "orm_order_status": 9,
          "status_comments": "IC DUE - Auto moved to Instruction Call Due after 48hrs",
          "status_date": "2020-04-15",
        }
      ]
    }

Sure:

public HttpResponseMessage Post()
{
    // ... do the job

    // now redirect
    var response = Request.CreateResponse(HttpStatusCode.Moved);
    response.Headers.Location = new Uri("http://www.abcmvc.com");
    return response;
}

I've found different compilers return different results on true. I've also found that one is almost always better off comparing a bool to a bool instead of an int. Those ints tend to change value over time as your program evolves and if you assume true as 1, you can get bitten by an unrelated change elsewhere in your code.

Martin Fowler did an interesting blog post last year about non-relational databases starting to gain traction. He mentions:

• Drizzle (a "bare bones" relational database)
• CouchDB (a document-oriented database)
• GemStone (an object-oriented database)

There is also Google's BigTable which is described as "a sparse, distributed multi-dimensional sorted map".

I have been working with GemStone for a number of years now and the productivity gains is amazing - having the database store your objects directly removes the need to constantly marshall back and forth between tables and objects.

This will actually be the correct answer:

function scrolled(event) {
   const container = event.target.body
   const {clientHeight, scrollHeight, scrollY: scrollTop} = container

   if (clientHeight + scrollY >= scrollHeight) {
    scrolledToBottom(event);
   }
}

The reason for using the event is up-to-date data, if you'll use a direct reference to the div you'll get outdated scrollY and will fail to detect the position correctly.

additional way is to wrap it in a setTimeout and wait till the data updates.

The first <img /> is invalid - src is a required attribute. data-src is an attribute than can be leveraged by, say, JavaScript, but has no presentational meaning.

Here it is a simpler way to achieve that:

1. Set the three elements' container (#outer) display: table
2. And set the elements themselves (#inner) display: table-cell
3. Remove the floating.
4. Success.

#outer{
    display: table;
}
#inner {
    display: table-cell;
    float: none;
}

Another way to refresh the current page using selenium in Java.

//first: get the current URL in a String variable
String currentURL = driver.getCurrentUrl(); 
//second: call the current URL
driver.get(currentURL); 

Using this will refresh the current page like clicking the address bar of the browser and pressing enter.

My .env:

#!/bin/bash
set -a # export all variables

#comments as usual, this is a bash script
USER=foo
PASS=bar

set +a #stop exporting variables

Invoking:

source .env; echo $USER; echo $PASS

The highly regarded Joda Time library is also worth a look. This is basis for the new date and time api that is pencilled in for Java 7. The design is neat, intuitive, well documented and avoids a lot of the clumsiness of the original java.util.Date / java.util.Calendar classes.

Joda's DateFormatter can parse a String to a Joda DateTime.

just add to div

style="overflow:hidden;"

Install nmap,

sudo apt-get install nmap

then

nmap -sP 192.168.1.*

or more commonly

nmap -sn 192.168.1.0/24

will scan the entire .1 to .254 range

This does a simple ping scan in the entire subnet to see which hosts are online.

Reviewing the Apple Developer documentation I found the CFUUID object is available on the iPhone OS 2.0 and later.

If you're using Python 2.x on Windows you need to change your line open('test.csv', 'w') to open('test.csv', 'wb'). That is you should open the file as a binary file.

However, as stated by others, the file interface has changed in Python 3.x.

pd.wide_to_long

You can add a prefix to your year columns and then feed directly to pd.wide_to_long. I won't pretend this is efficient, but it may in certain situations be more convenient than pd.melt, e.g. when your columns already have an appropriate prefix.

df.columns = np.hstack((df.columns[:2], df.columns[2:].map(lambda x: f'Value{x}')))

res = pd.wide_to_long(df, stubnames=['Value'], i='name', j='Date').reset_index()\
        .sort_values(['location', 'name'])

print(res)

   name        Date location  Value
0  test    Jan-2010        A     12
2  test    Feb-2010        A     20
4  test  March-2010        A     30
1   foo    Jan-2010        B     18
3   foo    Feb-2010        B     20
5   foo  March-2010        B     25

I consistently run into this problem. I believe it has to do with android studio not being aware of dynamically generated files. If you have everything else right for databinding try to File > Invalidate Caches/Restart... and select Invalidate Caches and Restart. Then try and import the BR file... it should import fine.

You may have to throw in a Clean and Rebuild.

The problem is the indexing subplot is using. Subplots are counted starting with 1! Your code thus needs to read

fig=plt.figure(figsize=(15, 6),facecolor='w', edgecolor='k')
for i in range(10):

    #this part is just arranging the data for contourf 
    ind2 = py.find(zz==i+1)
    sfr_mass_mat = np.reshape(sfr_mass[ind2],(pixmax_x,pixmax_y))
    sfr_mass_sub = sfr_mass[ind2]
    zi = griddata(massloclist, sfrloclist, sfr_mass_sub,xi,yi,interp='nn')


    temp = 251+i  # this is to index the position of the subplot
    ax=plt.subplot(temp)
    ax.contourf(xi,yi,zi,5,cmap=plt.cm.Oranges)
    plt.subplots_adjust(hspace = .5,wspace=.001)

    #just annotating where each contour plot is being placed
    ax.set_title(str(temp))

Note the change in the line where you calculate temp

Found something like that:

//javascript:
function playSound( url ){   
  document.getElementById("sound").innerHTML="<embed src='"+url+"' hidden=true autostart=true loop=false>";
} 

All above answers are great, but I will suggest an other option:

<style name="FlatButtonStyle" parent="Base.Widget.AppCompat.Button">
 <item name="android:stateListAnimator">@null</item>
 <!-- more style custom here --> 
</style>

since async ajax is deprecated try using nested async functions with a Promise. There may be syntax errors.

async function fetch_my_data(_url, _dat) {

   async function promised_fetch(_url, _dat) {

      return new Promise((resolve, reject) => {
         $.ajax({
            url:  _url,
            data: _dat,
            type: 'POST',
            success: (response) => {
               resolve(JSON.parse(response));
            },
            error: (response) => {
               reject(response);
            }
         });
      });
   }

   var _data = await promised_fetch(_url, _dat);
   
   return _data;
}

var _my_data = fetch_my_data('server.php', 'get_my_data=1');

FLAnimatedImage is a performant open source animated GIF engine for iOS:

• Plays multiple GIFs simultaneously with a playback speed comparable to desktop browsers
• Honors variable frame delays
• Behaves gracefully under memory pressure
• Eliminates delays or blocking during the first playback loop
• Interprets the frame delays of fast GIFs the same way modern browsers do

It's a well-tested component that I wrote to power all GIFs in Flipboard.

Disclaimer:

The OP has made this comment on another answer:

We can have ngDisabled for buttons or input tags; by using CSS we can make the button to look like anchor tag but that doesn't help much! I was more keen on looking how it can be done using directive approach or angular way of doing it?

You can use a variable inside the scope of your controller to disable the links/buttons according to the last button/link that you've clicked on by using ng-click to set the variable at the correct value and ng-disabled to disable the button when needed according to the value in the variable.

I've updated your Plunker to give you an idea.

But basically, it's something like this:

 <div>
       <button ng-click="create()" ng-disabled="state === 'edit'">CREATE</button><br/>
       <button ng-click="edit()" ng-disabled="state === 'create'">EDIT</button><br/>
       <button href="" ng-click="delete()" ng-disabled="state === 'create' || state === 'edit'">DELETE</button>
    </div>

Something I have noticed in my scripts at least is that exit() will stop the currently executing script and pass control back to any calling script, while die will stop php in its tracks. I would say that is quite a big difference?

for multiple occurrence and the character found in string??yes or no

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class SubStringtest {

    public static void main(String[] args)throws Exception {
    BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
     System.out.println("enter the string");
    String str=br.readLine();
    System.out.println("enter the character which you want");
    CharSequence ch=br.readLine();   
    boolean bool=str.contains(ch);
    System.out.println("the character found is " +bool);
    int position=str.indexOf(ch.toString());

    while(position>=0){
        System.out.println("the index no of character is " +position); 
        position=str.indexOf(ch.toString(),position+1);
    }


    }

}

Check your servers error log, typically /var/log/apache2/error.log.

Create and similar object for comparison works too ex:

from datetime import datetime, date

now = datetime.now()
today = date.today()

# compare now with today
two_month_earlier = date(now.year, now.month - 2, now.day)
if two_month_earlier > today:
    print(True)

two_month_earlier = datetime(now.year, now.month - 2, now.day)
if two_month_earlier > now:
   print("this will work with datetime too")

In case if you are under proxy environment and internet is not running in your emulator, then please don't change any setting in emulator. Go to your eclipse project, right click , click on "Run as" then click on "Run Configuration". In pop up window choose "Target" and scroll down a little, you will find "Additional Emulator Command Line Options" Enter your proxy setting here in "Additional Emulator Command Line Options" as i entered

-http-proxy http://ee11s040:[email protected]:3128

Then start a new Emulator.

I found that there was a syntax error in the related module and it wasn't compiling - the compiler didn't tell me that though. Just gave me the error regarding the app.config stuff. VS2010. Once I had fixed the syntax error, all was good.

Here is how you push a register. I assume we are talking about x86.

push ebx
push eax

It is pushed on stack. The value of ESP register is decremented to size of pushed value as stack grows downwards in x86 systems.

It is needed to preserve the values. The general usage is

push eax           ;   preserve the value of eax
call some_method   ;   some method is called which will put return value in eax
mov  edx, eax      ;    move the return value to edx
pop  eax           ;    restore original eax

A push is a single instruction in x86, which does two things internally.

1. Decrement the ESP register by the size of pushed value.
2. Store the pushed value at current address of ESP register.

A pure virtual function is usually not (but can be) implemented in a base class and must be implemented in a leaf subclass.

You denote that fact by appending the "= 0" to the declaration, like this:

class AbstractBase
{
    virtual void PureVirtualFunction() = 0;
}

Then you cannot declare and instantiate a subclass without it implementing the pure virtual function:

class Derived : public AbstractBase
{
    virtual void PureVirtualFunction() override { }
}

By adding the override keyword, the compiler will ensure that there is a base class virtual function with the same signature.

I only write shell scripts now and then and fall out of practice, so any feedback is appreciated.

Using the strategy proposed by @Arvid Requate, we noticed some user errors. A user who forgets to include a value will accidentally have the next option's name treated as a value:

./getopts_test.sh --loglevel= --toc=TRUE

will cause the value of "loglevel" to be seen as "--toc=TRUE". This can be avoided.

I adapted some ideas about checking user error for CLI from http://mwiki.wooledge.org/BashFAQ/035 discussion of manual parsing. I inserted error checking into handling both "-" and "--" arguments.

Then I started fiddling around with the syntax, so any errors in here are strictly my fault, not the original authors.

My approach helps users who prefer to enter long with or without the equal sign. That is, it should have same response to "--loglevel 9" as "--loglevel=9". In the --/space method, it is not possible to know for sure if the user forgets an argument, so some guessing is needed.

1. if the user has the long/equal sign format (--opt=), then a space after = triggers an error because an argument was not supplied.
2. if user has long/space arguments (--opt ), this script causes a fail if no argument follows (end of command) or if argument begins with dash)

In case you are starting out on this, there is an interesting difference between "--opt=value" and "--opt value" formats. With the equal sign, the command line argument is seen as "opt=value" and the work to handle that is string parsing, to separate at the "=". In contrast, with "--opt value", the name of the argument is "opt" and we have the challenge of getting the next value supplied in the command line. That's where @Arvid Requate used ${!OPTIND}, the indirect reference. I still don't understand that, well, at all, and comments in BashFAQ seem to warn against that style (http://mywiki.wooledge.org/BashFAQ/006). BTW, I don't think previous poster's comments about importance of OPTIND=$(( $OPTIND + 1 )) are correct. I mean to say, I see no harm from omitting it.

In newest version of this script, flag -v means VERBOSE printout.

Save it in a file called "cli-5.sh", make executable, and any of these will work, or fail in the desired way

./cli-5.sh  -v --loglevel=44 --toc  TRUE
./cli-5.sh  -v --loglevel=44 --toc=TRUE
./cli-5.sh --loglevel 7
./cli-5.sh --loglevel=8
./cli-5.sh -l9

./cli-5.sh  --toc FALSE --loglevel=77
./cli-5.sh  --toc=FALSE --loglevel=77

./cli-5.sh   -l99 -t yyy
./cli-5.sh   -l 99 -t yyy

Here is example output of the error-checking on user intpu

$ ./cli-5.sh  --toc --loglevel=77
ERROR: toc value must not have dash at beginning
$ ./cli-5.sh  --toc= --loglevel=77
ERROR: value for toc undefined

You should consider turning on -v, because it prints out internals of OPTIND and OPTARG

If anybody needs a simple thing, following is a simple key-expiring set. It might be converted to a map easily.

public class CacheSet<K> {
    public static final int TIME_OUT = 86400 * 1000;

    LinkedHashMap<K, Hit> linkedHashMap = new LinkedHashMap<K, Hit>() {
        @Override
        protected boolean removeEldestEntry(Map.Entry<K, Hit> eldest) {
            final long time = System.currentTimeMillis();
            if( time - eldest.getValue().time > TIME_OUT) {
                Iterator<Hit> i = values().iterator();

                i.next();
                do {
                    i.remove();
                } while( i.hasNext() && time - i.next().time > TIME_OUT );
            }
            return false;
        }
    };


    public boolean putIfNotExists(K key) {
        Hit value = linkedHashMap.get(key);
        if( value != null ) {
            return false;
        }

        linkedHashMap.put(key, new Hit());
        return true;
    }

    private static class Hit {
        final long time;


        Hit() {
            this.time = System.currentTimeMillis();
        }
    }
}

• Make a copy of your OpenSSL config in your home directory:

  cp /System/Library/OpenSSL/openssl.cnf ~/openssl-temp.cnf
  

  or on Linux:

  cp /etc/ssl/openssl.cnf ~/openssl-temp.cnf
  

• Add Subject Alternative Name to openssl-temp.cnf, under [v3_ca]:

  [ v3_ca ]
  subjectAltName = DNS:localhost
  

  Replace localhost by the domain for which you want to generate that certificate.

• Generate certificate:

  sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 \
      -config ~/openssl-temp.cnf
      -keyout /path/to/your.key -out /path/to/your.crt
  

You can then delete openssl-temp.cnf

This is caused because all the changes to the RemoteViews are serialised (e.g. setInt and setImageViewBitmap ). The bitmaps are also serialised into an internal bundle. Unfortunately this bundle has a very small size limit.

You can solve it by scaling down the image size this way:

 public static Bitmap scaleDownBitmap(Bitmap photo, int newHeight, Context context) {

 final float densityMultiplier = context.getResources().getDisplayMetrics().density;        

 int h= (int) (newHeight*densityMultiplier);
 int w= (int) (h * photo.getWidth()/((double) photo.getHeight()));

 photo=Bitmap.createScaledBitmap(photo, w, h, true);

 return photo;
 }

Choose newHeight to be small enough (~100 for every square it should take on the screen) and use it for your widget, and your problem will be solved :)

Just updated older Ubuntu versions to openJDK 11
Actually I need it for Jenkins only and it seems to work fine.

Ubuntu 12.04 (Precise):
Download from openjdk-lts (11.0.4+11-1~12.04) precise
Files:
openjdk-11-jre-headless_11.0.4+11-1~12.04_amd64.deb
openjdk-11-jre_11.0.4+11-1~12.04_amd64.deb

Ubuntu 14.04 (Trusty):
Download from openjdk-lts (11.0.5+10-2ubuntu1~14.04) trusty
Files:
openjdk-11-jre-headless_11.0.5+10-2ubuntu1_14.04_amd64.deb
openjdk-11-jre_11.0.5+10-2ubuntu1_14.04_amd64.deb

Installation
After download I installed the files with Ubuntu Software Center ("headless" first!)
Then I selected the new version with sudo update-alternatives --config java

I didn't have to change any environment variables (like JAVA_HOME) - maybe Jenkins doesn't care about them...

In newer versions of PHP, "extension_dir" is not initially enabled.

These lines worked in my case,

ClassLoader classLoader = getClass().getClassLoader();
File fi = new File(classLoader.getResource("test.txt").getFile());

provided test.txt file inside src

Alternatively you can use npm which automatically looks into the .bin folder. Then you can use tsc

I was really looking for a way to fetch the connection status of a device, not listen to connection events. Here's what worked for me:

BluetoothManager bm = (BluetoothManager) context.getSystemService(Context.BLUETOOTH_SERVICE);
List<BluetoothDevice> devices = bm.getConnectedDevices(BluetoothGatt.GATT);
int status = -1;

for (BluetoothDevice device : devices) {
  status = bm.getConnectionState(device, BLuetoothGatt.GATT);
  // compare status to:
  //   BluetoothProfile.STATE_CONNECTED
  //   BluetoothProfile.STATE_CONNECTING
  //   BluetoothProfile.STATE_DISCONNECTED
  //   BluetoothProfile.STATE_DISCONNECTING
}

Tables work differently; sometimes counter-intuitively.

The solution is to use width on the table cells instead of max-width.

Although it may sound like in that case the cells won't shrink below the given width, they will actually.
with no restrictions on c, if you give the table a width of 70px, the widths of a, b and c will come out as 16, 42 and 12 pixels, respectively.
With a table width of 400 pixels, they behave like you say you expect in your grid above.
Only when you try to give the table too small a size (smaller than a.min+b.min+the content of C) will it fail: then the table itself will be wider than specified.

I made a snippet based on your fiddle, in which I removed all the borders and paddings and border-spacing, so you can measure the widths more accurately.

table {_x000D_
  width: 70px;_x000D_
}_x000D_
_x000D_
table, tbody, tr, td {_x000D_
  margin: 0;_x000D_
  padding: 0;_x000D_
  border: 0;_x000D_
  border-spacing: 0;_x000D_
}_x000D_
_x000D_
.a, .c {_x000D_
  background-color: red;_x000D_
}_x000D_
_x000D_
.b {_x000D_
  background-color: #F77;_x000D_
}_x000D_
_x000D_
.a {_x000D_
  min-width: 10px;_x000D_
  width: 20px;_x000D_
  max-width: 20px;_x000D_
}_x000D_
_x000D_
.b {_x000D_
  min-width: 40px;_x000D_
  width: 45px;_x000D_
  max-width: 45px;_x000D_
}_x000D_
_x000D_
.c {}

<table>_x000D_
  <tr>_x000D_
    <td class="a">A</td>_x000D_
    <td class="b">B</td>_x000D_
    <td class="c">C</td>_x000D_
  </tr>_x000D_
</table>

To be totally exhaustive, things are different if you're using a JPA 1.0 or a JPA 2.0 implementation.

JPA 1.0

With JPA 1.0, you'd have to use EntityManager#getDelegate(). But keep in mind that the result of this method is implementation specific i.e. non portable from application server using Hibernate to the other. For example with JBoss you would do:

org.hibernate.Session session = (Session) manager.getDelegate();

But with GlassFish, you'd have to do:

org.hibernate.Session session = ((org.hibernate.ejb.EntityManagerImpl) em.getDelegate()).getSession(); 

I agree, that's horrible, and the spec is to blame here (not clear enough).

JPA 2.0

With JPA 2.0, there is a new (and much better) EntityManager#unwrap(Class<T>) method that is to be preferred over EntityManager#getDelegate() for new applications.

So with Hibernate as JPA 2.0 implementation (see 3.15. Native Hibernate API), you would do:

Session session = entityManager.unwrap(Session.class);

If the file is only numerical values separated by tabs, try using the csv library: http://docs.python.org/library/csv.html (you can set the delimiter to '\t')

If you have a textual file in which every line represents a row in a matrix and has integers separated by spaces\tabs, wrapped by a 'arrayname = [...]' syntax, you should do something like:

import re
f = open("your-filename", 'rb')
result_matrix = []
for line in f.readlines():
    match = re.match(r'\s*\w+\s+\=\s+\[(.*?)\]\s*', line)
    if match is None:
        pass # line syntax is wrong - ignore the line
    values_as_strings = match.group(1).split()
    result_matrix.append(map(int, values_as_strings))

This is the solution I used to automatically change between SCROLLABLE and FIXED+FILL. It is the complete code for the @Fighter42 solution:

(The code below shows where to put the modification if you've used Google's tabbed activity template)

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    // Create the adapter that will return a fragment for each of the three
    // primary sections of the activity.
    mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());

    // Set up the ViewPager with the sections adapter.
    mViewPager = (ViewPager) findViewById(R.id.container);
    mViewPager.setAdapter(mSectionsPagerAdapter);

    // Set up the tabs
    final TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
    tabLayout.setupWithViewPager(mViewPager);

    // Mario Velasco's code
    tabLayout.post(new Runnable()
    {
        @Override
        public void run()
        {
            int tabLayoutWidth = tabLayout.getWidth();

            DisplayMetrics metrics = new DisplayMetrics();
            ActivityMain.this.getWindowManager().getDefaultDisplay().getMetrics(metrics);
            int deviceWidth = metrics.widthPixels;

            if (tabLayoutWidth < deviceWidth)
            {
                tabLayout.setTabMode(TabLayout.MODE_FIXED);
                tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
            } else
            {
                tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
            }
        }
    });
}

Layout:

    <android.support.design.widget.TabLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal" />

If you don't need to fill width, better to use @karaokyo solution.

You can use the provider-specific ConnectionStringBuilder class (within the appropriate namespace), or System.Data.Common.DbConnectionStringBuilder to abstract the connection string object if you need to. You'd need to know the provider-specific keywords used to designate the information you're looking for, but for a SQL Server example you could do either of these two things:

System.Data.SqlClient.SqlConnectionStringBuilder builder = new System.Data.SqlClient.SqlConnectionStringBuilder(connectionString);

string server = builder.DataSource;
string database = builder.InitialCatalog;

or

System.Data.Common.DbConnectionStringBuilder builder = new System.Data.Common.DbConnectionStringBuilder();

builder.ConnectionString = connectionString;

string server = builder["Data Source"] as string;
string database = builder["Initial Catalog"] as string;

I got this error after using asdf to switch my python version. When you activate the virtualenv it gets confused.

Instead recreate the virtualenv like so

$ rm -rf venv
$ python -m venv venv

This time when you activate the virtualenv it will find the correct python.

q or SHIFT+q will do the trick. This will get you out of many extensive page scrolling sessions like git status, git show HEAD, git diff etc. This will not exit your window or end your session.

You may store the parameters for the blob detector in a file, but this is not necessary. Example:

// set up the parameters (check the defaults in opencv's code in blobdetector.cpp)
cv::SimpleBlobDetector::Params params;
params.minDistBetweenBlobs = 50.0f;
params.filterByInertia = false;
params.filterByConvexity = false;
params.filterByColor = false;
params.filterByCircularity = false;
params.filterByArea = true;
params.minArea = 20.0f;
params.maxArea = 500.0f;
// ... any other params you don't want default value

// set up and create the detector using the parameters
cv::SimpleBlobDetector blob_detector(params);
// or cv::Ptr<cv::SimpleBlobDetector> detector = cv::SimpleBlobDetector::create(params)

// detect!
vector<cv::KeyPoint> keypoints;
blob_detector.detect(image, keypoints);

// extract the x y coordinates of the keypoints: 

for (int i=0; i<keypoints.size(); i++){
    float X = keypoints[i].pt.x; 
    float Y = keypoints[i].pt.y;
}

This code worked fine for me.

 import java.io.FileOutputStream;
 import java.io.IOException;
 import java.io.InputStream;
 import java.io.OutputStream;
 import java.net.URL;

public class SaveImageFromUrl {

public static void main(String[] args) throws Exception {
    String imageUrl = "http://www.avajava.com/images/avajavalogo.jpg";
    String destinationFile = "image.jpg";

    saveImage(imageUrl, destinationFile);
}

public static void saveImage(String imageUrl, String destinationFile) throws IOException {
    URL url = new URL(imageUrl);
    InputStream is = url.openStream();
    OutputStream os = new FileOutputStream(destinationFile);

    byte[] b = new byte[2048];
    int length;

    while ((length = is.read(b)) != -1) {
        os.write(b, 0, length);
    }

    is.close();
    os.close();
}

}

This prints it in the console:

echo %cd%

or paste this command in CMD, then you'll have pwd:

(echo @echo off
echo echo ^%cd^%) > C:\WINDOWS\pwd.bat

I faced to the same problem. I solved it by

1. navigate to HKEY_CURRENT_USER\Software\Python\PythonCore\3.4\InstallPath and edit the default key with the output of C:\> where python.exe command.
2. navigate to HKEY_CURRENT_USER\Software\Python\PythonCore\3.4\InstallPath\InstallGroup and edit the default key with Python 3.4

Note: My python version is 3.4 and you need to replace 3.4 with your python version.

Normally you can find Registry entries for Python in HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\<version>. You just need to copy those entries to HKEY_CURRENT_USER\Software\Python\PythonCore\<version>

You can. I'm using the following lines in a StackExchange Data Explorer query:

SELECT
(SELECT COUNT(*) FROM VotesOnPosts WHERE VoteTypeName = 'UpMod' AND UserId = @UserID AND PostTypeId = 2) AS TotalUpVotes,
(SELECT COUNT(*) FROM Answers WHERE UserId = @UserID) AS TotalAnswers

The Data Exchange uses Transact-SQL (the SQL Server proprietary extensions to SQL).

You can try it yourself by running a query like:

SELECT 'Hello world'

The following snippets test for the "not contains" condition, as exemplified in the sample pseudocode in the question. For a direct solution with explicit looping, do this:

boolean contains = false;
for (char c : charArray) {
    if (c == 'q') {
        contains = true;
        break;
    }
}
if (!contains) {
    // do something
}

Another alternative, using the fact that String provides a contains() method:

if (!(new String(charArray).contains("q"))) {
    // do something
}

Yet another option, this time using indexOf():

if (new String(charArray).indexOf('q') == -1) {
    // do something
}

Language features:

Templates and Generic Code

• Template argument deduction for class templates

  • Like how functions deduce template arguments, now constructors can deduce the template arguments of the class
  • http://wg21.link/p0433r2 http://wg21.link/p0620r0 http://wg21.link/p0512r0

• template <auto>

  • Represents a value of any (non-type template argument) type.

• Non-type template arguments fixes

• template<template<class...>typename bob> struct foo {}

• ( Folding + ... + expressions ) and Revisions

• auto x{8}; is an int

• modernizing using with ... and lists

Lambda

• constexpr lambdas

  • Lambdas are implicitly constexpr if they qualify

• Capturing *this in lambdas

  • [*this]{ std::cout << could << " be " << useful << '\n'; }

Attributes

• [[fallthrough]], [[nodiscard]], [[maybe_unused]] attributes

• [[attributes]] on namespaces and enum { erator[[s]] }

• using in attributes to avoid having to repeat an attribute namespace.

• Compilers are now required to ignore non-standard attributes they don't recognize.

  • The C++14 wording allowed compilers to reject unknown scoped attributes.

Syntax cleanup

• Inline variables

  • Like inline functions
  • Compiler picks where the instance is instantiated
  • Deprecate static constexpr redeclaration, now implicitly inline.

• namespace A::B

• Simple static_assert(expression); with no string

• no throw unless throw(), and throw() is noexcept(true).

Cleaner multi-return and flow control

• Structured bindings

  • Basically, first-class std::tie with auto
  • Example:
    • const auto [it, inserted] = map.insert( {"foo", bar} );
    • Creates variables it and inserted with deduced type from the pair that map::insert returns.
  • Works with tuple/pair-likes & std::arrays and relatively flat structs
  • Actually named structured bindings in standard

• if (init; condition) and switch (init; condition)

  • if (const auto [it, inserted] = map.insert( {"foo", bar} ); inserted)
  • Extends the if(decl) to cases where decl isn't convertible-to-bool sensibly.

• Generalizing range-based for loops

  • Appears to be mostly support for sentinels, or end iterators that are not the same type as begin iterators, which helps with null-terminated loops and the like.

• if constexpr

  • Much requested feature to simplify almost-generic code.

Misc

• Hexadecimal float point literals

• Dynamic memory allocation for over-aligned data

• Guaranteed copy elision

  • Finally!
  • Not in all cases, but distinguishes syntax where you are "just creating something" that was called elision, from "genuine elision".

• Fixed order-of-evaluation for (some) expressions with some modifications

  • Not including function arguments, but function argument evaluation interleaving now banned

Isocpp.org has has an independent list of changes since C++14; it has been partly pillaged.

Naturally TS work continues in parallel, so there are some TS that are not-quite-ripe that will have to wait for the next iteration. The target for the next iteration is C++20 as previously planned, not C++19 as some rumors implied. C++1O has been avoided.

Initial list taken from this reddit post and this reddit post, with links added via googling or from the above isocpp.org page.

Additional entries pillaged from SD-6 feature-test list.

clang's feature list and library feature list are next to be pillaged. This doesn't seem to be reliable, as it is C++1z, not C++17.

these slides had some features missing elsewhere.

While "what was removed" was not asked, here is a short list of a few things ((mostly?) previous deprecated) that are removed in C++17 from C++:

Removed:

• register, keyword reserved for future use
• bool b; ++b;
• trigraphs
  • if you still need them, they are now part of your source file encoding, not part of language
• ios aliases
• auto_ptr, old <functional> stuff, random_shuffle
• allocators in std::function

There were rewordings. I am unsure if these have any impact on code, or if they are just cleanups in the standard:

Papers not yet integrated into above:

• P0505R0 (constexpr chrono)

• P0418R2 (atomic tweaks)

• P0512R0 (template argument deduction tweaks)

• P0490R0 (structured binding tweaks)

• P0513R0 (changes to std::hash)

• P0502R0 (parallel exceptions)

• P0509R1 (updating restrictions on exception handling)

• P0012R1 (make exception specifications be part of the type system)

• P0510R0 (restrictions on variants)

• P0504R0 (tags for optional/variant/any)

• P0497R0 (shared ptr tweaks)

• P0508R0 (structured bindings node handles)

• P0521R0 (shared pointer use count and unique changes?)

Spec changes:

• exception specs and throw expressions

  • Should be updated to "Modifications to existing features" here.

The includes() method determines whether one string may be found within another string, returning true or false as appropriate.

Syntax :-string.includes(searchString[, position])

searchString:-A string to be searched for within this string.

position:-Optional. The position in this string at which to begin searching for searchString; defaults to 0.

string = 'LOL';
console.log(string.includes('lol')); // returns false 
console.log(string.includes('LOL')); // returns true 

It's a very bad idea to directly display any text on an irregular and ever changing background. No matter what you do, some of the time the text will be hard to read.

The best design would be to have the labels on a constant background with the images changing behind that.

You can set the labels background color from clear to white and set the from alpha to 50.0 you get a nice translucent effect. The only problem is that the label's background is a stark rectangle.

To get a label with a background with rounded corners you can use a button with user interaction disabled but the user might mistake that for a button.

The best method would be to create image of the label background you want and then put that in an imageview and put the label with the default transparent background onto of that.

Plain UIViews do not have an image background. Instead, you should make a UIImageView your main view and then rotate the images though its image property. If you set the UIImageView's mode to "Scale to fit" it will scale any image to fit the bounds of the view.

DECLARE @Dat

SELECT * 
FROM Jai
WHERE                                                                                                          
CONVERT(VARCHAR(2),DATEPART("dd",Date)) +'/'+                                                              
             CONVERT(VARCHAR(2),DATEPART("mm",Date)) +'/'+              
                     CONVERT(VARCHAR(4), DATEPART("yy",Date)) = @Dat

Brian Ramsay’s code, de-pseudofied:

- (NSString*)formattedStringForDuration:(NSTimeInterval)duration
{
    NSInteger minutes = floor(duration/60);
    NSInteger seconds = round(duration - minutes * 60);
    return [NSString stringWithFormat:@"%d:%02d", minutes, seconds];
}

One reason that the constructor is deprecated is that the meaning of the year parameter is not what you would expect. The javadoc says:

As of JDK version 1.1, replaced by Calendar.set(year + 1900, month, date).

Notice that the year field is the number of years since 1900, so your sample code most likely won't do what you expect it to do. And that's the point.

In general, the Date API only supports the modern western calendar, has idiosyncratically specified components, and behaves inconsistently if you set fields.

The Calendar and GregorianCalendar APIs are better than Date, and the 3rd-party Joda-time APIs were generally thought to be the best. In Java 8, they introduced the java.time packages, and these are now the recommended alternative.

Finding a value in a list and then deleting that index (if it exists) is easier done by just using list's remove method:

>>> a = [1, 2, 3, 4]
>>> try:
...   a.remove(6)
... except ValueError:
...   pass
... 
>>> print a
[1, 2, 3, 4]
>>> try:
...   a.remove(3)
... except ValueError:
...   pass
... 
>>> print a
[1, 2, 4]

If you do this often, you can wrap it up in a function:

def remove_if_exists(L, value):
  try:
    L.remove(value)
  except ValueError:
    pass

git gc --aggressive is one way to force the prune process to take place (to be sure: git gc --aggressive --prune=now). You have other commands to clean the repo too. Don't forget though, sometimes git gc alone can increase the size of the repo!

It can be also used after a filter-branch, to mark some directories to be removed from the history (with a further gain of space); see here. But that means nobody is pulling from your public repo. filter-branch can keep backup refs in .git/refs/original, so that directory can be cleaned too.

Finally, as mentioned in this comment and this question; cleaning the reflog can help:

git reflog expire --all --expire=now
git gc --prune=now --aggressive

An even more complete, and possibly dangerous, solution is to remove unused objects from a git repository

Update Feb. 2021, eleven years later: the new git maintenance command (man page) should supersede git gc, and can be scheduled.

Restarting my ng serve process worked for me

Save the file as *.txt and then rename the file and change the file extension to json

Android UI creation using layouts, resources, activities and intents is an implementation of the MVC pattern. Please see the following link for more on this - http://www.cs.otago.ac.nz/cosc346/labs/COSC346-lab2.2up.pdf

Try:

if (_checkbox.addEventListener) {
    _checkbox.addEventListener("click", setCheckedValues, false);
}
else {
    _checkbox.attachEvent("onclick", setCheckedValues);
}

Update:: For Internet Explorer versions prior to IE9, attachEvent method should be used to register the specified listener to the EventTarget it is called on, for others addEventListener should be used.

I have tried almost all the answers and some of them almost worked for me but none of these answers work perfectly. So here is my solution. For this solution, you will need to add onclick attribute in the HTML body tag. So if you can not modify the HTML file then this solution won't work for you.

Step 1: add onclick attribute in the HTML body tag like this:

<body onclick="ok.performClick(this.value);">
    <h1>This is heading 1</h1>
    <p>This is para 1</p>
</body>

Step 2: implement addJavascriptInterface in your app to handle click listener:

webView.addJavascriptInterface(new Object() {
    @JavascriptInterface
    public void performClick(String string) {
        handler.sendEmptyMessageDelayed(CLICK_ON_WEBVIEW, 0);
    }
}, "ok");

Step 3: We can not perform any action on main thread from performClick method so need to add Handler class:

private final Handler handler = new Handler(this); // class-level variable 
private static final int CLICK_ON_WEBVIEW = 1; // class-level variable 

implement Handler.Callback to your class and the override handleMessage

@Override
public boolean handleMessage(Message message) {
    if (message.what == CLICK_ON_WEBVIEW) {
        Toast.makeText(getActivity(), "WebView clicked", Toast.LENGTH_SHORT).show();
        return true;
    }
    return false;
}

Instead of using doubles for decimal arithemetic, please use java.math.BigDecimal. It would produce the expected results.

For reference take a look at this stackoverflow question

One answer I'm missing here: Multi-layer perceptron is able to find relation between features. For example it is necessary in computer vision when a raw image is provided to the learning algorithm and now Sophisticated features are calculated. Essentially the intermediate levels can calculate new unknown features.

SELECT a.* FROM 
FROM tbl_1 a
MINUS
SELECT b.* FROM 
FROM tbl_2 b

If the browser people see this as a security and/or usability problem, then the answer to your question is to simply not close the window, since by definition they will come up with solutions for your workaround anyway. There is a nice summation about the reasoning why the choice have been in the firefox bug database https://bugzilla.mozilla.org/show_bug.cgi?id=190515#c70

So what can you do?

Change the specification of your website, so that you have a solution for these people. You could for instance take it as an opportunity to direct them to a partner.

That is, see it as a handoff to someone else that (potentially) needs it. As an example, Hanselman had a recent article about what to do in the other similar situation, namely 404 errors: http://www.hanselman.com/blog/PutMissingKidsOnYour404PageEntirelyClientSideSolutionWithYQLJQueryAndMSAjax.aspx

According to their FAQ, GIT doesn't track empty directories.

Git FAQ

However, there are workarounds based on your needs and your project requirements.

Basically if you want to track an empty directory you can place a .gitkeep file in there. The file can be blank and it will just work. This is Gits way of tracking an empty directory.

Another option is to provide documentation for the directory. You can just add a readme file in it describing its expected usage. Git will track the folder because it has a file in it and you have now provided documentation to you and/or whoever else might be using the source code.

If you are building a web app you may find it useful to just add an index.html file which may contain a permission denied message if the folder is only accessible through the app. Codeigniter does this with all their directories.
