Pure bash (no fork!)

There is a way, using a bash function. This way is very quick as there is no fork!...

... While bunch of ip addresses stay small!

countIp () { 
    local -a _ips=(); local _a
    while IFS=. read -a _a ;do
        ((_ips[_a<<24|${_a[1]}<<16|${_a[2]}<<8|${_a[3]}]++))
    done
    for _a in ${!_ips[@]} ;do
        printf "%.16s %4d\n" \
          $(($_a>>24)).$(($_a>>16&255)).$(($_a>>8&255)).$(($_a&255)) ${_ips[_a]}
    done
}

Note: IP addresses are converted to 32bits unsigned integer value, used as index for array. This use simple bash arrays, not associative array (wich is more expensive)!

time countIp < ip_addresses 
10.0.10.1    3
10.0.10.2    1
10.0.10.3    1
real    0m0.001s
user    0m0.004s
sys     0m0.000s

time sort ip_addresses | uniq -c
      3 10.0.10.1
      1 10.0.10.2
      1 10.0.10.3
real    0m0.010s
user    0m0.000s
sys     0m0.000s

On my host, doing so is a lot quicker than using forks, upto approx 1'000 addresses, but take approx 1 entire second when I'll try to sort'n count 10'000 addresses.

Open the httpd.conf file and search for

"rewrite"

, then remove

"#"

at the starting of the line,so the line looks like.

LoadModule rewrite_module modules/mod_rewrite.so

then restart the wamp.

If you don't want to change your markup, this function does the trick:

jQuery('button').click( function(e) {
    jQuery('.collapse').collapse('hide');
});

Whenever a BUTTON is clicked, all sections become collapsed. Then bootstrap opens the one you selected.

You're trying to invoke an instance method on the class it self.

You should do:

    Random rand = new Random();
    int a = 0 ; 
    while (!done) { 
        int a = rand.nextInt(10) ; 
    ....

Instead

As I told you here stackoverflow.com/questions/2694470/whats-wrong...

Go with this

body {
    padding:0px;
    margin:0px;
}

You can use Contains() for that. It will feel a little backwards when you're really trying to produce an IN clause, but this should do it:

var userProfiles = _dataContext.UserProfile
                               .Where(t => idList.Contains(t.Id));

I'm also assuming that each UserProfile record is going to have an int Id field. If that's not the case you'll have to adjust accordingly.

You can generate a stack trace and use the informations in the StackTraceElements.

For example an utility class can return you the calling class name :

public class KDebug {
    public static String getCallerClassName() { 
        StackTraceElement[] stElements = Thread.currentThread().getStackTrace();
        for (int i=1; i<stElements.length; i++) {
            StackTraceElement ste = stElements[i];
            if (!ste.getClassName().equals(KDebug.class.getName()) && ste.getClassName().indexOf("java.lang.Thread")!=0) {
                return ste.getClassName();
            }
        }
        return null;
     }
}

If you call KDebug.getCallerClassName() from bar(), you'll get "foo".

Now supposing you want to know the class of the method calling bar (which is more interesting and maybe what you really wanted). You could use this method :

public static String getCallerCallerClassName() { 
    StackTraceElement[] stElements = Thread.currentThread().getStackTrace();
    String callerClassName = null;
    for (int i=1; i<stElements.length; i++) {
        StackTraceElement ste = stElements[i];
        if (!ste.getClassName().equals(KDebug.class.getName())&& ste.getClassName().indexOf("java.lang.Thread")!=0) {
            if (callerClassName==null) {
                callerClassName = ste.getClassName();
            } else if (!callerClassName.equals(ste.getClassName())) {
                return ste.getClassName();
            }
        }
    }
    return null;
 }

Is that for debugging ? If not, there may be a better solution to your problem.

As of 2020 and Go version 1.13+, in Windows the best way for updating GOPATH is just typing in command prompt:

setx GOPATH C:\mynewgopath

You add your ActionListener twice to button. So correct your code for button2 to

  JButton button2 = new JButton("hello agin2");
  panel.add(button2);
  button2.addActionListener (new Action2());//note the button2 here instead of button

Furthermore, perform your Swing operations on the correct thread by using EventQueue.invokeLater

size_t is returned by various libraries to indicate that the size of that container is non-zero. You use it when you get once back :0

However, in the your example above looping on a size_t is a potential bug. Consider the following:

for (size_t i = thing.size(); i >= 0; --i) {
  // this will never terminate because size_t is a typedef for
  // unsigned int which can not be negative by definition
  // therefore i will always be >= 0
  printf("the never ending story. la la la la");
}

the use of unsigned integers has the potential to create these types of subtle issues. Therefore imho I prefer to use size_t only when I interact with containers/types that require it.

The clearfix allows a container to wrap its floated children. Without a clearfix or equivalent styling, a container does not wrap around its floated children and collapses, just as if its floated children were positioned absolutely.

There are several versions of the clearfix, with Nicolas Gallagher and Thierry Koblentz as key authors.

If you want support for older browsers, it's best to use this clearfix :

.clearfix:before, .clearfix:after {
    content: "";
    display: table;
}

.clearfix:after {
    clear: both;
}

.clearfix {
    *zoom: 1;
}

In SCSS, you could use the following technique :

%clearfix {
    &:before, &:after {
        content:" ";
        display:table;
    }

    &:after {
        clear:both;
    }

    & {
        *zoom:1;
    }
}

#clearfixedelement {
    @extend %clearfix;
}

If you don't care about supporting older browsers, there's a shorter version :

.clearfix:after {
    content:"";
    display:table;
    clear:both;
}

I don't know how the table is created but try this...

SELECT users1.user_id, users2.user_parent_id
FROM users AS users1
INNER JOIN users AS users2
ON users1.id = users2.id
WHERE users1.user_id = users2.user_parent_id

You've created a new repository and added some files to the index, but you haven't created your first commit yet. After you've done:

 git add a_text_file.txt 

... do:

 git commit -m "Initial commit."

... and those errors should go away.

You can use the path module to join the path of the directory in which helper1.js lives to the relative path of foobar.json. This will give you the absolute path to foobar.json.

var fs = require('fs');
var path = require('path');

var jsonPath = path.join(__dirname, '..', 'config', 'dev', 'foobar.json');
var jsonString = fs.readFileSync(jsonPath, 'utf8');

This should work on Linux, OSX, and Windows assuming a UTF8 encoding.

This index size limit seems to be larger on 64 bit builds of MySQL.

I was hitting this limitation trying to dump our dev database and load it on a local VMWare virt. Finally I realized that the remote dev server was 64 bit and I had created a 32 bit virt. I just created a 64 bit virt and I was able to load the database locally.

Please try either of these commands first;

$ py -m notebook
$ python -m notebook

for jupyterlab users

py -m jupyterlab

Otherwise

$ python -m pip install jupyter --user
$ jupyter notebook

If this does not work.

pip does not add jupyter directly to path for local.

The output from

$ which python
/c/Users/<username>/AppData/Local/Programs/Python/Python35-32/python

After some digging I found a executable for jupyter in the folder:

C:\Users\<username>\AppData\Roaming\Python\Python35\Scripts\jupyter.exe

Difference between local and roaming folder

So if you want to be able to execute a program via command line, you need to add it into the %PATH variable. Here is a powershell script to do it. BE SURE TO ADD THE ";" before adding the new path.

$ [Environment]::SetEnvironmentVariable("Path", $env:Path + ";C:\Users\<username>\AppData\Roaming\Python\Python35\Scripts", [EnvironmentVariableTarget]::User)

Update:

if you are using python3, switch out python with python3 but I encourage you to use pyenv instead :)

your approach is pretty good...

.myclass {_x000D_
    height: 20px;_x000D_
    position: relative;_x000D_
    border: 2px solid #cdcdcd;_x000D_
    border-color: rgba(0, 0, 0, .14);_x000D_
    background-color: AliceBlue;_x000D_
    font-size: 14px;_x000D_
}

<input type="text" class="myclass" />

Please execute the following steps:

1. Open the command prompt
2. Change directory to the required path

3. Give the following command

   del /S *.svn
   

:%s/$/\*/g

should work and so should :%s/$/*/g.

How about just:

Date expiry = new Date(Long.parseLong(date));

EDIT: as per rde6173's answer and taking a closer look at the input specified in the question , "1081157732" appears to be a seconds-based epoch value so you'd want to multiply the long from parseLong() by 1000 to convert to milliseconds, which is what Java's Date constructor uses, so:

Date expiry = new Date(Long.parseLong(date) * 1000);

Since mobile doesn't give hover feedback, I want, as a user, to see instant feedback when a link is tapped. I noticed that -webkit-tap-highlight-color is the fastest to respond (subjective).

Add the following to your body and your links will have a tap effect.

body {
    -webkit-tap-highlight-color: #ccc;
}

Simply use Contains method. Note that it works based on the equality function Equals

bool alreadyExist = list.Contains(item);

Try adding C:\Program Files\Nodejs to your PATH environment variable. The PATH environment variable allows run executables or access files within the folders specified (separated by semicolons).

On the command prompt, the command would be set PATH=%PATH%;C:\Program Files\Nodejs.

-- replace NVARCHAR(42) with the actual type of your column
ALTER TABLE your_table
ALTER COLUMN your_column NVARCHAR(42) NULL

I am running PHP version 5.4 on shared hosting and both of these both successfully return the same results:

php_uname('n');

gethostname();

It exists a property called XmlElementAttribute.IsNullable

If the IsNullable property is set to true, the xsi:nil attribute is generated for class members that have been set to a null reference.

The following example shows a field with the XmlElementAttribute applied to it, and the IsNullable property set to false.

public class MyClass
{
   [XmlElement(IsNullable = false)]
   public string Group;
}

You can have a look to other XmlElementAttribute for changing names in serialization etc.

In Python 3.x and 2.x you can use use list to force a copy of the keys to be made:

for i in list(d):

In Python 2.x calling keys made a copy of the keys that you could iterate over while modifying the dict:

for i in d.keys():

But note that in Python 3.x this second method doesn't help with your error because keys returns an a view object instead of copynig the keys into a list.

You will need to know if the REST API you are calling supports GET or POST, or both methods. The code below is something that works for me, I'm calling my own web service API, so I already know what the API takes and what it will return. It supports both GET and POST methods, so the less sensitive info goes into the URL (GET), and the info like username and password is submitted as POST variables. Also, everything goes over the HTTPS connection.

Inside the API code, I encode an array I want to return into json format, then simply use PHP command echo $my_json_variable to make that json string availabe to the client.

So as you can see, my API returns json data, but you need to know (or look at the returned data to find out) what format the response from the API is in.

This is how I connect to the API from the client side:

$processed = FALSE;
$ERROR_MESSAGE = '';

// ************* Call API:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.myapi.com/api.php?format=json&action=subscribe&email=" . $email_to_subscribe);
curl_setopt($ch, CURLOPT_POST, 1);// set post data to true
curl_setopt($ch, CURLOPT_POSTFIELDS,"username=myname&password=mypass");   // post data
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$json = curl_exec($ch);
curl_close ($ch);

// returned json string will look like this: {"code":1,"data":"OK"}
// "code" may contain an error code and "data" may contain error string instead of "OK"
$obj = json_decode($json);

if ($obj->{'code'} == '1')
{
  $processed = TRUE;
}else{
  $ERROR_MESSAGE = $obj->{'data'};
}

...

if (!$processed && $ERROR_MESSAGE != '') {
    echo $ERROR_MESSAGE;
}

BTW, I also tried to use file_get_contents() method as some of the users here suggested, but that din't work well for me. I found out the curl method to be faster and more reliable.

If you want to make a change global to the whole notebook:

You'll need to use UNION to combine the results of two queries. In your case:

SELECT ChargeNum, CategoryID, SUM(Hours)
FROM KnownHours
GROUP BY ChargeNum, CategoryID
UNION ALL
SELECT ChargeNum, 'Unknown' AS CategoryID, SUM(Hours)
FROM UnknownHours
GROUP BY ChargeNum

Note - If you use UNION ALL as in above, it's no slower than running the two queries separately as it does no duplicate-checking.

Git will not store the password when you use URLs like that. Instead, it will just store the username, so it only needs to prompt you for the password the next time. As explained in the manual, to store the password, you should use an external credential helper. For Windows, you can use the Windows Credential Store for Git. This helper is also included by default in GitHub for Windows.

When using it, your password will automatically be remembered, so you only need to enter it once. So when you clone, you will be asked for your password, and then every further communication with the remote will not prompt you for your password again. Instead, the credential helper will provide Git with the authentication.

This of course only works for authentication via https; for ssh access ([email protected]/repository.git) you use SSH keys and those you can remember using ssh-agent (or PuTTY’s pageant if you’re using plink).

I would suggest you use the below css

.showhideoverlay { 
  width: 100%;
  height: 100%;
  right: 0px;
  top: 0px;
  position: fixed;
  background: #000;
  opacity: 0.75;
}

You can then use a simple toggle function:

$('a.open').click(function() {
  $('div.showhideoverlay').toggle("slow");
});

This will display the overlay menu from right to left. Alternatively, you can use the positioning for changing the effect from top or bottom, i.e. use bottom: 0; instead of top: 0; - you will see menu sliding from right-bottom corner.

 figure (1)
 hFig = figure(1);
 set(gcf,'PaperPositionMode','auto')
 set(hFig, 'Position', [0 0 xwidth ywidth])
 plot(x,y)
 print -depsc2 correlation.eps;       % for saving in eps, look up options for saving as png or other formats you may need

This saves the figure in the dimensions specified

also you can reimplement protected member QWidget::closeEvent()

void YourWidgetWithXButton::closeEvent(QCloseEvent *event)
{
    // do what you need here
    // then call parent's procedure
    QWidget::closeEvent(event);
}

Start with the triangle...

    *
   **
  ***
 ****

representing 1+2+3+4 so far. Cut the triangle in half along one dimension...

     *
    **
  * **
 ** **

Rotate the smaller part 180 degrees, and stick it on top of the bigger part...

    **
    * 

     *

Close the gap to get a rectangle.

At first sight this only works if the base of the rectangle has an even length - but if it has an odd length, you just cut the middle column in half - it still works with a half-unit-wide twice-as-tall (still integer area) strip on one side of your rectangle.

Whatever the base of the triangle, the width of your rectangle is (base / 2) and the height is (base + 1), giving ((base + 1) * base) / 2.

However, my base is your n-1, since the bubble sort compares a pair of items at a time, and therefore iterates over only (n-1) positions for the first loop.

I used the built-in rstrip function to do it like follow:

string = "test.com"
suffix = ".com"
newstring = string.rstrip(suffix)
print(newstring)
test

My answer seems like less code and it works for me:

    class Nose {
      constructor() {
        this.booger = 'ready'; 
      }
      
      pick() {
        console.log('pick your nose')
      } 
    }
    
    class Ear {
      constructor() {
        this.wax = 'ready'; 
      }
      
      dig() {
        console.log('dig in your ear')
      } 
    }
    
    class Gross extends Classes([Nose,Ear]) {
      constructor() {
        super();
        this.gross = true;
      }
    }
    
    function Classes(bases) {
      class Bases {
        constructor() {
          bases.forEach(base => Object.assign(this, new base()));
        }
      }
      bases.forEach(base => {
        Object.getOwnPropertyNames(base.prototype)
        .filter(prop => prop != 'constructor')
        .forEach(prop => Bases.prototype[prop] = base.prototype[prop])
      })
      return Bases;
    }

    
    // test it
    
    var grossMan = new Gross();
    grossMan.pick(); // eww
    grossMan.dig();  // yuck!

Facelets is a XML based view technology. The & is a special character in XML representing the start of an entity like & which ends with the ; character. You'd need to either escape it, which is ugly:

rendered="#{beanA.prompt == true && beanB.currentBase != null}"

or to use the and keyword instead, which is preferred as to readability and maintainability:

rendered="#{beanA.prompt == true and beanB.currentBase != null}"

See also:

• Java EE 6 tutorial - Operators in EL

Unrelated to the concrete problem, comparing booleans with booleans makes little sense when the expression expects a boolean outcome already. I'd get rid of == true:

rendered="#{beanA.prompt and beanB.currentBase != null}"

I really like the approach posted by "orange80". It's elegant because you can set it once and forget it.

The other approaches require you to do something different (call something other than plain console.log() every time), which is just asking for trouble… I know that I'd eventually forget.

I've taken it a step further, by wrapping the code in a utility function that you can call once at the beginning of your javascript, anywhere as long as it's before any logging. (I'm installing this in my company's event data router product. It will help simplify the cross-browser design of its new admin interface.)

/**
 * Call once at beginning to ensure your app can safely call console.log() and
 * console.dir(), even on browsers that don't support it.  You may not get useful
 * logging on those browers, but at least you won't generate errors.
 * 
 * @param  alertFallback - if 'true', all logs become alerts, if necessary. 
 *   (not usually suitable for production)
 */
function fixConsole(alertFallback)
{    
    if (typeof console === "undefined")
    {
        console = {}; // define it if it doesn't exist already
    }
    if (typeof console.log === "undefined") 
    {
        if (alertFallback) { console.log = function(msg) { alert(msg); }; } 
        else { console.log = function() {}; }
    }
    if (typeof console.dir === "undefined") 
    {
        if (alertFallback) 
        { 
            // THIS COULD BE IMPROVED… maybe list all the object properties?
            console.dir = function(obj) { alert("DIR: "+obj); }; 
        }
        else { console.dir = function() {}; }
    }
}

If the database link option is not available, another route you could take is to link the tables via ODBC to something such as MS Access or Crystal reports and do the join there.

This function works with variables for size and initial value it combines tbur & Filipe responses.

Function ArrayIniValue(iSize As Integer, iValue As Integer)
Dim sIndex As String
sIndex = "INDEX(Row(1:" & iSize & "),)"
ArrayIniValue = Evaluate("=Transpose(" & sIndex & "-" & sIndex & "+" & iValue & ")")
End Function

Called this way:

myArray = ArrayIniValue(350, 13)

You specifically asked for "extension or functionality in Chrome and/or Firefox", which the answers you have already received provide, but I do like the simplicity of oezi's answer to the closed question "how to send a post request with a web browser" for simple parameters. oezi says:

with a form, just set method to "post"

<form action="blah.php" method="post">
  <input type="text" name="data" value="mydata" />
  <input type="submit" />
</form>

I.e. build yourself a very simple page to test the post actions.

Try this easy and it works

let input = elem.querySelector('input[type="file"]');
input.outerHTML=input.outerHTML;

this will reset the input

There is a bug where Xcode 6 launch images stored in asset files cause iphone landscape only apps on iOS7/iOS8 to display a black launch image. iPad works fine.

http://www.raywenderlich.com/forums/viewtopic.php?f=2&t=10868

Solution: Use the new Launchscreen.xib for ios8+ onwards. (it is far better)

For ios7 devices to work you simply turn off launch images source and use the old school launch images file names in the plist

iphone5 - [email protected] 
iphone4s - [email protected]
ipad2 - Default-Landscape~ipad.png
ipad retina - Default-Landscape@2x~ipad.png

Painful but works. B

I answered something like this in another question already, but will change it just a little for this one.

Unfortunately, there is no getImageResource() or getDrawableId(). But, I created a simple workaround by using the ImageView tags.

In onCreate():

imageView0 = (ImageView) findViewById(R.id.imageView0);
imageView1 = (ImageView) findViewById(R.id.imageView1);
imageView2 = (ImageView) findViewById(R.id.imageView2);

imageView0.setTag(R.drawable.apple);
imageView1.setTag(R.drawable.banana);
imageView2.setTag(R.drawable.cereal);

Then, if you like, you can create a simple function to get the drawable id:

private int getDrawableId(ImageView iv) {
    return (Integer) iv.getTag();
}

Too easy.

jQuery module can be installed using:

npm install jquery

Example:

var $ = require('jquery');
var http = require('http');

var options = {
    host: 'jquery.com',
    port: 80,
    path: '/'
};

var html = '';
http.get(options, function(res) {
res.on('data', function(data) {
    // collect the data chunks to the variable named "html"
    html += data;
}).on('end', function() {
    // the whole of webpage data has been collected. parsing time!
    var title = $(html).find('title').text();
    console.log(title);
 });
});

Those will be null (or maybe undefined) when they're not relevant to the referring window's situation. ("Referring window" means the window in whose context the JavaScript code is run.)

similar to cletu's solution, but i got an error using that solution, this is the workaround:

works fine on me

Try Jedi! There's a Vim plugin at https://github.com/davidhalter/jedi-vim.

It works just much better than anything else for Python in Vim. It even has support for renaming, goto, etc. The best part is probably that it really tries to understand your code (decorators, generators, etc. Just look at the feature list).

If is a package then you can get the source for that with:

    select text from all_source where name = 'PADCAMPAIGN' 
    and type = 'PACKAGE BODY'
    order by line;

Oracle doesn't store the source for a sub-program separately, so you need to look through the package source for it.

Note: I've assumed you didn't use double-quotes when creating that package, but if you did , then use

    select text from all_source where name = 'pAdCampaign' 
    and type = 'PACKAGE BODY'
    order by line;

BufferedReader can't wrap an InputStream directly. It wraps another Reader. In this case you'd want to do something like:

BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"));

Try these to clarify the issue of right alignment in float point printing

printf(" 4|%4.1lf\n", 8.9);
printf("04|%04.1lf\n", 8.9);

the output is

 4| 8.9

For readability, I'd go with

char * s = malloc(snprintf(NULL, 0, "%s %s", first, second) + 1);
sprintf(s, "%s %s", first, second);

If your platform supports GNU extensions, you could also use asprintf():

char * s = NULL;
asprintf(&s, "%s %s", first, second);

If you're stuck with the MS C Runtime, you have to use _scprintf() to determine the length of the resulting string:

char * s = malloc(_scprintf("%s %s", first, second) + 1);
sprintf(s, "%s %s", first, second);

The following will most likely be the fastest solution:

size_t len1 = strlen(first);
size_t len2 = strlen(second);

char * s = malloc(len1 + len2 + 2);
memcpy(s, first, len1);
s[len1] = ' ';
memcpy(s + len1 + 1, second, len2 + 1); // includes terminating null

I'd say the minimum would be to

• know one of the .Net Languages (C#, VB.NET, etc.)
• know the basic working of the .Net runtime
• know and understand the core parts of the .Net class libraries
• have an understanding about what additional classes and functions are available as part of the .Net class libraries

The only problem is that any additional certificates in resulted file will not be recognized, as tools don't expect more than one certificate per PEM/DER encoded file. Even openssl itself. Try

openssl x509 -outform DER -in certificate.cer | openssl x509 -inform DER -outform PEM

and see for yourself.

You need to delete the deployment, which should in turn delete the pods and the replica sets https://github.com/kubernetes/kubernetes/issues/24137

To list all deployments:

kubectl get deployments --all-namespaces

Then to delete the deployment:

kubectl delete -n NAMESPACE deployment DEPLOYMENT

Where NAMESPACE is the namespace it's in, and DEPLOYMENT is the name of the deployment.

In some cases it could also be running due to a job or daemonset. Check the following and run their appropriate delete command.

kubectl get jobs

kubectl get daemonsets.app --all-namespaces

kubectl get daemonsets.extensions --all-namespaces

ViewBag and ViewData are two means which are used to pass information from controller to view in ASP.Net MVC. The goal of using both mechanism is to provide the communicaton between controller and View. Both have short life that is the value of both becomes null once the redirection has occured ie, once the page has redirected from the source page (where we set the value of ViewBag or ViewData) to the target page , both ViewBag as well as ViewData becomes null.

Despite having these similarities both (ViewBag and ViewData) are two different things if we talk about the implementation of both. The differences are as follows :

1.) If we analyse both implementation wise then we will find that ViewData is a dictionary data structure - Dictionary of Objects derived from ViewDataDictionary and accessible using strings as Keys to these values while ViewBag makes use of the dynamic features introduced in C#4.0 and is a dynamic property.

2.) While accessing the values form ViewData , we need to typecast the values (datatypes) as they are stored as Objects in the ViewData dictionary but there is no such need if we are accessing th value in case of ViewBag.

3.) In ViewBag we can set the value like this :

      ViewBag.Name = "Value"; 

and can access as follows:

          @ViewBag.Name

While in case of ViewData the values can be set and accessed as follows: Setting ViewData as follows :

ViewData["Name"] = "Value";

and accessing value like this

 @ViewData["Name"]

Alternative solution, where you can have the database in the folder you want inside the solution. That worked for me:

.ConnectionString(@"Data Source=LocalDB)\MSSQLLocalDB;
                    AttachDbFilename="+AppDomain.CurrentDomain.BaseDirectory+"Folder1\\Folder2\\SampleDatabase.mdf" + ";
                    Integrated Security=True;")

Just clear the plots and try executing the code again...It worked for me

Instead of converting to varchar to get just the day (convert(varchar(8), [Date], 112)), I prefer keeping it a datetime field and making it only the date (without the time).

SELECT * FROM Results 
WHERE CONVERT(date, [Date]) >= CONVERT(date, GETDATE())

use std::stringstream

unsigned int x;   
std::stringstream ss;
ss << std::hex << "fffefffe";
ss >> x;

the following example produces -65538 as its result:

#include <sstream>
#include <iostream>

int main() {
    unsigned int x;   
    std::stringstream ss;
    ss << std::hex << "fffefffe";
    ss >> x;
    // output it as a signed type
    std::cout << static_cast<int>(x) << std::endl;
}

In the new C++11 standard, there are a few new utility functions which you can make use of! specifically, there is a family of "string to number" functions (http://en.cppreference.com/w/cpp/string/basic_string/stol and http://en.cppreference.com/w/cpp/string/basic_string/stoul). These are essentially thin wrappers around C's string to number conversion functions, but know how to deal with a std::string

So, the simplest answer for newer code would probably look like this:

std::string s = "0xfffefffe";
unsigned int x = std::stoul(s, nullptr, 16);

NOTE: Below is my original answer, which as the edit says is not a complete answer. For a functional solution, stick the code above the line :-).

It appears that since lexical_cast<> is defined to have stream conversion semantics. Sadly, streams don't understand the "0x" notation. So both the boost::lexical_cast and my hand rolled one don't deal well with hex strings. The above solution which manually sets the input stream to hex will handle it just fine.

Boost has some stuff to do this as well, which has some nice error checking capabilities as well. You can use it like this:

try {
    unsigned int x = lexical_cast<int>("0x0badc0de");
} catch(bad_lexical_cast &) {
    // whatever you want to do...
}

If you don't feel like using boost, here's a light version of lexical cast which does no error checking:

template<typename T2, typename T1>
inline T2 lexical_cast(const T1 &in) {
    T2 out;
    std::stringstream ss;
    ss << in;
    ss >> out;
    return out;
}

which you can use like this:

// though this needs the 0x prefix so it knows it is hex
unsigned int x = lexical_cast<unsigned int>("0xdeadbeef"); 

Try this:

Xvfb :21 -screen 0 1024x768x24 +extension RANDR &

Xvfb --help

+extension name        Enable extension
-extension name        Disable extension

Since std::distance is only constant time for random-access iterators, I would probably prefer explicit iterator arithmetic. Also, since we're writing C++ code here, I do believe a more C++ idiomatic solution is preferable over a C-style approach.

string str{"Test string"};
auto begin = str.begin();

for (auto it = str.begin(), end = str.end(); it != end; ++it)
{
    cout << it - begin << *it;
}

Can't comment on the answer given by @Paul Grime yet, anyway I've submitted on his github project the fix for the flicker problem....

I'll post the fix here, maybe someone needs it. You just need to add two lines of code. The first one below the anim.setAnimationListener call:

anim.setFillAfter(true);

And the second one after app.layout() call:

app.clearAnimation();

Hope this helps :)

A current release of Android Studio did not correctly apply the -tcpdump argument. I was still able to capture a dump by passing the related parameter to qemu as follows:

tools/emulator -engine classic -tcpdump dump.cap -avd myAvd

I got same error because I was trying to run on

XXX-Macmini:Python-Project XXX.XXX$ from classDemo import MyClass

from: can't read /var/mail/classDemo

To solve this, type command python and when you get these >>> then run any python commands

>>>from classDemo import MyClass
>>>f = MyClass()

None of these answers seemed intuitive enough, so I created a small directive to do this. This way allows you to declare the title in the page, where one would normally do it, and allows it to be dynamic as well.

angular.module('myModule').directive('pageTitle', function() {
    return {
        restrict: 'EA',
        link: function($scope, $element) {
            var el = $element[0];
            el.hidden = true; // So the text not actually visible on the page

            var text = function() {
                return el.innerHTML;
            };
            var setTitle = function(title) {
                document.title = title;
            };
            $scope.$watch(text, setTitle);
        }
    };
});

You'll need to of course change the module name to match yours.

To use it, just throw this in your view, much as you would do for a regular <title> tag:

<page-title>{{titleText}}</page-title>

You can also just include plain text if you don't need it to by dynamic:

<page-title>Subpage X</page-title>

Alternatively, you can use an attribute, to make it more IE-friendly:

<div page-title>Title: {{titleText}}</div>

You can put whatever text you want in the tag of course, including Angular code. In this example, it will look for $scope.titleText in whichever controller the custom-title tag is currently in.

Just make sure you don't have multiple page-title tags on your page, or they'll clobber each other.

Plunker example here http://plnkr.co/edit/nK63te7BSbCxLeZ2ADHV. You'll have to download the zip and run it locally in order to see the title change.

You should use CSS to align the textbox. The reason your code above does not work is because by default a div's width is the same as the container it's in, therefore in your example it is pushed below.

The following would work.

<td  colspan="2" class="cell">
                <asp:Label ID="Label6" runat="server" Text="Label"></asp:Label>        
                <asp:TextBox ID="TextBox3" runat="server" CssClass="righttextbox"></asp:TextBox>       
</td>

In your CSS file:

.cell
{
text-align:left;
}

.righttextbox
{
float:right;
}

• using: You are going to use it.
• namespace: To use what? A namespace.
• std: The std namespace (where features of the C++ Standard Library, such as string or vector, are declared).

After you write this instruction, if the compiler sees string it will know that you may be referring to std::string, and if it sees vector, it will know that you may be referring to std::vector. (Provided that you have included in your compilation unit the header files where they are defined, of course.)

If you don't write it, when the compiler sees string or vector it will not know what you are refering to. You will need to explicitly tell it std::string or std::vector, and if you don't, you will get a compile error.

Have you tried using the value in MB ?

php_value memory_limit 2048M

Also try editing this value in php.ini not Apache.

Calendar.get takes as argument one of the standard Calendar fields, like YEAR or MONTH not a month name.

Calendar.JANUARY is 0, which is also the value of Calendar.ERA, so Calendar.getInstance().get(0) will return the era, in this case Calendar.AD, which is 1.

For the first part of your question, note that, as is wildly documented, months start at 0, so 10 is actually November.

Reading the friendly manual? Who'd want to do that?

start = Time.now
largest_known_fixnum = 1
smallest_known_bignum = nil

until smallest_known_bignum == largest_known_fixnum + 1
  if smallest_known_bignum.nil?
    next_number_to_try = largest_known_fixnum * 1000
  else
    next_number_to_try = (smallest_known_bignum + largest_known_fixnum) / 2 # Geometric mean would be more efficient, but more risky
  end

  if next_number_to_try <= largest_known_fixnum ||
       smallest_known_bignum && next_number_to_try >= smallest_known_bignum
    raise "Can't happen case" 
  end

  case next_number_to_try
    when Bignum then smallest_known_bignum = next_number_to_try
    when Fixnum then largest_known_fixnum = next_number_to_try
    else raise "Can't happen case"
  end
end

finish = Time.now
puts "The largest fixnum is #{largest_known_fixnum}"
puts "The smallest bignum is #{smallest_known_bignum}"
puts "Calculation took #{finish - start} seconds"

Your example works because you are passing the address of your variable to a function that manipulates its value with the dereference operator.

While C does not support reference data types, you can still simulate passing-by-reference by explicitly passing pointer values, as in your example.

The C++ reference data type is less powerful but considered safer than the pointer type inherited from C. This would be your example, adapted to use C++ references:

void f(int &j) {
  j++;
}

int main() {
  int i = 20;
  f(i);
  printf("i = %d\n", i);

  return 0;
}

Short answer: You can't.

Long answer:

Due to the way generics is implemented in Java, the generic type T is not kept at runtime. Still, you can use a private data member:

public class Foo<T> 
{
    private Class<T> type;

    public Foo(Class<T> type) { this.type = type; } 
}

Usage example:

Foo<Integer> test = new Foo<Integer>(Integer.class);

Going back to the original question (4 years later), rather than rebuilding your own section header, iOS can simply call you (with willDisplayHeaderView:forSection:) right after it's built the default one. For example, I wanted to add a graph button on right edge of section header:

- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section {
    UITableViewHeaderFooterView * header = (UITableViewHeaderFooterView *) view;
    if (header.contentView.subviews.count >  0) return; //in case of reuse
    CGFloat rightEdge = CGRectGetMaxX(header.contentView.bounds);
    UIButton * button = [[UIButton alloc] initWithFrame:CGRectMake(rightEdge - 44, 0, 44, CGRectGetMaxY(header.contentView.bounds))];
    [button setBackgroundImage:[UIImage imageNamed:@"graphIcon"] forState:UIControlStateNormal];
    [button addTarget:self action:@selector(graphButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
    [view addSubview:button];
}

alternative solution with awk and double parenthesis:

FILENAME=file.txt
SIZE=$(du -sb $FILENAME | awk '{ print $1 }')

if ((SIZE<90000)) ; then 
    echo "less"; 
else 
    echo "not less"; 
fi

class flag:
    ## Store pseudo-global variables here

    keys=False

    sword=True

    torch=False


## test the flag class

print('______________________')

print(flag.keys)
print(flag.sword)
print (flag.torch)


## now change the variables

flag.keys=True
flag.sword= not flag.sword
flag.torch=True

print('______________________')

print(flag.keys)
print(flag.sword)
print (flag.torch)

That's actually pretty easy, here's a possible approach:

<table>
    <tr>
        <th>
            <a href="?orderBy=type">Type:</a>
        </th>
        <th>
            <a href="?orderBy=description">Description:</a>
        </th>
        <th>
            <a href="?orderBy=recorded_date">Recorded Date:</a>
        </th>
        <th>
            <a href="?orderBy=added_date">Added Date:</a>
        </th>
    </tr>
</table>
<?php
$orderBy = array('type', 'description', 'recorded_date', 'added_date');

$order = 'type';
if (isset($_GET['orderBy']) && in_array($_GET['orderBy'], $orderBy)) {
    $order = $_GET['orderBy'];
}

$query = 'SELECT * FROM aTable ORDER BY '.$order;

// retrieve and show the data :)
?>

That'll do the trick! :)

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

type AnimalSounder interface {
    MakeNoise()
}

type Dog struct {
    Name string
    mean bool
    BarkStrength int
}

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

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

With Pathlib from python3 standard library:

Path(mypath).mkdir(parents=True, exist_ok=True)

If parents is true, any missing parents of this path are created as needed; they are created with the default permissions without taking mode into account (mimicking the POSIX mkdir -p command). If exist_ok is false (the default), an FileExistsError is raised if the target directory already exists.

If exist_ok is true, FileExistsError exceptions will be ignored (same behavior as the POSIX mkdir -p command), but only if the last path component is not an existing non-directory file.

Changed in version 3.5: The exist_ok parameter was added.

ES6 with Async / Await ,

let meaningOfLife = false;
async function waitForMeaningOfLife(){
   while (true){
        if (meaningOfLife) { console.log(42); return };
        await null; // prevents app from hanging
   }
}
waitForMeaningOfLife();
setTimeout(()=>meaningOfLife=true,420)

Taken from above:

For a two-tailed test:

Import numpy as np
z = 1.96

You can wrap your canvas element in a parent div, relatively positioned, then give that div the height you want, setting maintainAspectRatio: false in your options

//HTML
<div id="canvasWrapper" style="position: relative; height: 80vh/500px/whatever">
<canvas id="chart"></canvas>
</div>

<script>
new Chart(somechart, {
options: {
    responsive: true,
    maintainAspectRatio: false

/*, your other options*/

}
});
</script>

You could use an asymmetrical border to make curves with CSS.

Just want to add another way of doing this. I've seen multiple people on various related threads ask if you can use VerifyRenderingInServerForm without adding it to the parent page.

You actually can do this but it's a bit of a bodge.

First off create a new Page class which looks something like the following:

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

    public override void VerifyRenderingInServerForm(Control control)
    {
        //Allows for printing
    }

    public override bool EnableEventValidation
    {
        get { return false; }
        set { /*Do nothing*/ }
    }
}

Does not need to have an .ASPX associated with it.

Then in the control you wish to render you can do something like the following.

    StringWriter tw = new StringWriter();
    HtmlTextWriter hw = new HtmlTextWriter(tw);

    var page = new NoRenderPage();
    page.DesignerInitialize();
    var form = new HtmlForm();
    page.Controls.Add(form);
    form.Controls.Add(pnl);
    controlToRender.RenderControl(hw);

Now you've got your original control rendered as HTML. If you need to, add the control back into it's original position. You now have the HTML rendered, the page as normal and no changes to the page itself.

This should work.

using System.Drawing.Printing;

...

PrinterSettings ps = new PrinterSettings();
ps.PrinterName = "The printer name"; // Load the appropriate printer's setting

After that, the various properties of PrinterSettings can be read.

Note that ps.isValid() can see if the printer actually exists.

Edit: One additional comment. Microsoft recommends you use a PrintDocument and modify its PrinterSettings rather than creating a PrinterSettings directly.

I was hunting around for an answer to this question. I found this helpful. The pattern wasn't apparent in the documentation for with_items.

I had this error when accidentally putting the wmain inside a namespace. wmain should not be in any namespace. Moreover, I had a main function in one of the libs I was using, and VS took the main from there, what made it even stranger.

I most cases, creating a temporary file named after your variable name might be acceptable. (as you are probably using meaningful variables name...)

Here, my variable name is SSH_PAGEANT_AUTH_SOCK

dir /w "\\.\pipe\\"|find "pageant" > %temp%\SSH_PAGEANT_AUTH_SOCK && set /P SSH_PAGEANT_AUTH_SOCK=<%temp%\SSH_PAGEANT_AUTH_SOCK

As its name is "numbers" it is clear it is a list of number... So an array of number... no need of the attribute type... Although I like the principle of specifying the type of field in a type attribute...

It's generally not a real good idea to import the VisualBasic libraries into C# programs (not because they won't work, but just for compatibility, style, and ability to upgrade), but you can call Microsoft.VisualBasic.Interaction.InputBox() to display the kind of box you're looking for.

If you can create a Windows.Forms object, that would be best, but you say you cannot do that.

The list of supported tags is:

If you use a string resource, you can add some simple styling, such as bold or italic using HTML notation. The currently supported tags are: B (bold), I (italic), U (underline), TT (monospace), BIG, SMALL, SUP (superscript), SUB (subscript), and STRIKE (strikethrough). So, for example, in res/values/strings.xml you could declare this:

<resource>
    <string id="@+id/styled_welcome_message">We are <b><i>so</i></b> glad to see you.</string>
</resources>

(From http://developer.android.com/guide/faq/commontasks.html#selectingtext — Web Archive link, <resource> typo is in original!)

It also shows that Html.fromHtml isn't really needed in simple cases.

Why not one more answer? setState() and the setState()-triggered render() have both completed executing when you call componentDidMount() (the first time render() is executed) and/or componentDidUpdate() (any time after render() is executed). (Links are to ReactJS.org docs.)

Example with componentDidUpdate()

Caller, set reference and set state...

<Cmp ref={(inst) => {this.parent=inst}}>;
this.parent.setState({'data':'hello!'});

Render parent...

componentDidMount() {           // componentDidMount() gets called after first state set
    console.log(this.state.data);   // output: "hello!"
}
componentDidUpdate() {          // componentDidUpdate() gets called after all other states set
    console.log(this.state.data);   // output: "hello!"
}

Example with componentDidMount()

Caller, set reference and set state...

<Cmp ref={(inst) => {this.parent=inst}}>
this.parent.setState({'data':'hello!'});

Render parent...

render() {              // render() gets called anytime setState() is called
    return (
        <ChildComponent
            state={this.state}
        />
    );
}

After parent rerenders child, see state in componentDidUpdate().

componentDidMount() {           // componentDidMount() gets called anytime setState()/render() finish
console.log(this.props.state.data); // output: "hello!"
}

There are few things.

First, not /Graph but ./Graph

Second, when you use the TensorBoard callback, always pass validation data, because without it, it wouldn't start.

Third, if you want to use anything except scalar summaries, then you should only use the fit method because fit_generator will not work. Or you can rewrite the callback to work with fit_generator.

To add callbacks, just add it to model.fit(..., callbacks=your_list_of_callbacks)

You can add your attribute on callback function ({key} , speed.callback, like is

$('.usercontent').animate( {
    backgroundColor:'#ddd',
},1000,function () {
    $(this).css("backgroundColor","red")
});

As an alternative to $dollarsign notation, use a within block:

breast <- within(breast, {
  class <- as.numeric(as.character(class))
})

Note that you want to convert your vector to a character before converting it to a numeric. Simply calling as.numeric(class) will not the ids corresponding to each factor level (1, 2) rather than the levels themselves.

Click \Build\Select Build Variant... in Android Studio. And choose release.

For pure characters-of-code efficiency, I can't find anything better than

smallest = a<b&&a<c?a:b<c?b:c;

Use IList to get the JArray Count and Use Loop to Convert into List

       var array = result["items"].Value<JArray>();

        IList collection = (IList)array;

        var list = new List<string>();

        for (int i = 0; i < collection.Count; j++)
            {
              list.Add(collection[i].ToString());             
            }                         

Remove the project from your solution by right-clicking it in the Solution Explorer window and choosing Remove. Move the entire project folder, including subdirectories wherever you want it to go. Add the project back to your solution.

Namespace names is something completely different, just edit the source code.

This would work for BMP and SIP/SMP characters.

    String.prototype.lengthInUtf8 = function() {
        var asciiLength = this.match(/[\u0000-\u007f]/g) ? this.match(/[\u0000-\u007f]/g).length : 0;
        var multiByteLength = encodeURI(this.replace(/[\u0000-\u007f]/g)).match(/%/g) ? encodeURI(this.replace(/[\u0000-\u007f]/g, '')).match(/%/g).length : 0;
        return asciiLength + multiByteLength;
    }

    'test'.lengthInUtf8();
    // returns 4
    '\u{2f894}'.lengthInUtf8();
    // returns 4
    '???? ?????'.lengthInUtf8();
    // returns 19, each Arabic/Persian alphabet character takes 2 bytes. 
    '??,JavaScript ??'.lengthInUtf8();
    // returns 26, each Chinese character/punctuation takes 3 bytes.

        // ignore ssl error
        if (handler != null){
            handler.proceed();

I get this error from the sshfs command from Fedora 17 linux to debian linux on the Mindstorms EV3 brick over the LAN and through a wireless connection.

Bash command:

el@defiant /mnt $ sshfs [email protected]:/root -p 22 /mnt/ev3
fuse: bad mount point `/mnt/ev3': Transport endpoint is not connected

This is remedied with the following command and trying again:

fusermount -u /mnt/ev3

These additional sshfs options prevent the above error from concurring:

sudo sshfs -d -o allow_other -o reconnect -o ServerAliveInterval=15 [email protected]:/var/lib/redmine/plugins /mnt -p 12345 -C

In order to use allow_other above, you need to uncomment the last line in /etc/fuse.conf:

# Set the maximum number of FUSE mounts allowed to non-root users.
# The default is 1000.
#
#mount_max = 1000

# Allow non-root users to specify the 'allow_other' or 'allow_root'
# mount options.
#
user_allow_other

This question has been already answered with very good examples. The only example that might be missing is one where the functions return pointers. I wrote another example with this, and added lots of comments, in case someone finds it helpful:

#include <stdio.h>

char * func1(char *a) {
    *a = 'b';
    return a;
}

char * func2(char *a) {
    *a = 'c';
    return a;
}

int main() {
    char a = 'a';
    /* declare array of function pointers
     * the function pointer types are char * name(char *)
     * A pointer to this type of function would be just
     * put * before name, and parenthesis around *name:
     *   char * (*name)(char *)
     * An array of these pointers is the same with [x]
     */
    char * (*functions[2])(char *) = {func1, func2};
    printf("%c, ", a);
    /* the functions return a pointer, so I need to deference pointer
     * Thats why the * in front of the parenthesis (in case it confused you)
     */
    printf("%c, ", *(*functions[0])(&a)); 
    printf("%c\n", *(*functions[1])(&a));

    a = 'a';
    /* creating 'name' for a function pointer type
     * funcp is equivalent to type char *(*funcname)(char *)
     */
    typedef char *(*funcp)(char *);
    /* Now the declaration of the array of function pointers
     * becomes easier
     */
    funcp functions2[2] = {func1, func2};

    printf("%c, ", a);
    printf("%c, ", *(*functions2[0])(&a));
    printf("%c\n", *(*functions2[1])(&a));

    return 0;
}

If you want to stop every movie tag in your page from playing, this little snippet of jQuery will help you:

$("video").each(function () { this.pause() });

Try Tixik.com and their API there. They have a very different data that big players, really good coverage mostly in Europe and good API conditions.

Strings are immutable. But you can convert them to a list, which is mutable, and then convert the list back to a string after you've changed it.

s = "this is a string"

l = list(s)  # convert to list

l[1] = ""    # "delete" letter h (the item actually still exists but is empty)
l[1:2] = []  # really delete letter h (the item is actually removed from the list)
del(l[1])    # another way to delete it

p = l.index("a")  # find position of the letter "a"
del(l[p])         # delete it

s = "".join(l)  # convert back to string

You can also create a new string, as others have shown, by taking everything except the character you want from the existing string.

for inline style sheet try this code

<ul style="list-style-type: none;">
    <li>Try This</li>
    </ul>

Even though too much of CLOSE_WAIT connections means there is something wrong with your code in the first and this is accepted not good practice.

You might want to check out: https://github.com/rghose/kill-close-wait-connections

What this script does is send out the ACK which the connection was waiting for.

This is what worked for me.

There is also a function in pandas called factorize which you can use to automatically do this type of work. It converts labels to numbers: ['male', 'female', 'male'] -> [0, 1, 0]. See this answer for more information.

You can use the "vh" length unit for the min-height property of the element itself and its parents. It's supported since IE9:

<body class="full-height">
    <form id="form1">
    <div id="header">
        <a title="Home" href="index.html" />
    </div>

    <div id="menuwrapper">
        <div id="menu">
        </div>
    </div>

    <div id="content" class="full-height">
    </div>
</body>

CSS:

.full-height {
    min-height: 100vh;
    box-sizing: border-box;
}

I had the same problem, and found the answer. If you use node.js with express, you need to give it its own function in order for the js file to be reached. For example:

const script = path.join(__dirname, 'script.js');
const server = express().get('/', (req, res) => res.sendFile(script))

try: ->unique('column')

example:

$users = User::get()->unique('column');

For some reason this link solved my problem...I don't know why tho..

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.13.0/moment.min.js"></script>

Then this:

<script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datetimepicker/4.17.37/js/bootstrap-datetimepicker.min.js"></script>

NOTE: I am using Bootstrap 3 and Jquery 1.11.3

It's perfectly safe as long as you always access the values through the struct via the . (dot) or -> notation.

What's not safe is taking the pointer of unaligned data and then accessing it without taking that into account.

Also, even though each item in the struct is known to be unaligned, it's known to be unaligned in a particular way, so the struct as a whole must be aligned as the compiler expects or there'll be trouble (on some platforms, or in future if a new way is invented to optimise unaligned accesses).

this is best solution for me :)

$i=0;
foreach() if ($i < yourlimitnumber) {

$i +=1;
}

You can simply export the table with a query clause using datapump and import it back with table_exists_action=replace clause. Its will drop and recreate your table and take very less time. Please read about it before implementing.

This will return you the required cursor

Cursor cursor = db.query(TABLE_NAME, new String[] {"_id", "title", "title_raw"}, 
                "title_raw like " + "'%Smith%'", null, null, null, null);

There are problems with some data. Consider:

as.double(as.character("2.e")) # This results in 2

Another solution:

get_numbers <- function(X) {
    X[toupper(X) != tolower(X)] <- NA
    return(as.double(as.character(X)))
}

It basically execute the method call tag.name on each tags in the array.

It is a simplified ruby shorthand.

You can try SharpZipLib for that. Is is open source, platform independent pure c# code.

You need to reference the global variable in every function you want to use.

As follows:

var = "test"

def printGlobalText():
    global var #wWe are telling to explicitly use the global version
    var = "global from printGlobalText fun."
    print "var from printGlobalText: " + var

def printLocalText():
    #We are NOT telling to explicitly use the global version, so we are creating a local variable
    var = "local version from printLocalText fun"
    print "var from printLocalText: " + var

printGlobalText()
printLocalText()
"""
Output Result:
var from printGlobalText: global from printGlobalText fun.
var from printLocalText: local version from printLocalText
[Finished in 0.1s]
"""

Answer updated to Python 3.7 and more

Here is how you can turn a date-and-time object

(aka datetime.datetime object, the one that is stored inside models.DateTimeField django model field)

into a date object (aka datetime.date object):

from datetime import datetime

#your date-and-time object
# let's supposed it is defined as
datetime_element = datetime(2020, 7, 10, 12, 56, 54, 324893)

# where
# datetime_element = datetime(year, month, day, hour, minute, second, milliseconds)

# WHAT YOU WANT: your date-only object
date_element = datetime_element.date()

And just to be clear, if you print those elements, here is the output :

print(datetime_element)

2020-07-10 12:56:54.324893

print(date_element)

2020-07-10

One of the weird behaviour and spec in Javascript is the typeof Array is Object.

You can check if the variable is an array in couple of ways:

var isArr = data instanceof Array;
var isArr = Array.isArray(data);

But the most reliable way is:

isArr = Object.prototype.toString.call(data) == '[object Array]';

Since you tagged your question with jQuery, you can use jQuery isArray function:

var isArr = $.isArray(data);

To change the default property for your entire MATLAB session, see the documentation on how default properties are handled.

As an example:

set(0,'DefaultAxesFontSize',22)
x=1:200; y=sin(x);
plot(x,y)
title('hello'); xlabel('x'); ylabel('sin(x)')

BehaviourSubject

BehaviourSubject will return the initial value or the current value on Subscription

var bSubject= new Rx.BehaviorSubject(0);  // 0 is the initial value

bSubject.subscribe({
  next: (v) => console.log('observerA: ' + v)  // output initial value, then new values on `next` triggers
});

bSubject.next(1);  // output new value 1 for 'observer A'
bSubject.next(2);  // output new value 2 for 'observer A', current value 2 for 'Observer B' on subscription

bSubject.subscribe({
  next: (v) => console.log('observerB: ' + v)  // output current value 2, then new values on `next` triggers
});

bSubject.next(3);

With output:

observerA: 0
observerA: 1
observerA: 2
observerB: 2
observerA: 3
observerB: 3

Subject

Subject does not return the current value on Subscription. It triggers only on .next(value) call and return/output the value

var subject = new Rx.Subject();

subject.next(1); //Subjects will not output this value

subject.subscribe({
  next: (v) => console.log('observerA: ' + v)
});
subject.subscribe({
  next: (v) => console.log('observerB: ' + v)
});

subject.next(2);
subject.next(3);

With the following output on the console:

observerA: 2
observerB: 2
observerA: 3
observerB: 3

ASP.NET web forms page already have a JavaScript method for handling PostBacks called "__doPostBack".

function __doPostBack(eventTarget, eventArgument) {
    if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
        theForm.__EVENTTARGET.value = eventTarget;
        theForm.__EVENTARGUMENT.value = eventArgument;
        theForm.submit();
    }
}

Use the following in your code file to generate the JavaScript that performs the PostBack. Using this method will ensure that the proper ClientID for the control is used.

protected string GetLoginPostBack()
{
    return Page.ClientScript.GetPostBackEventReference(btnLogin, string.Empty);
}

Then in the ASPX page add a javascript block.

<script language="javascript">
function btnLogin_Click() {
  <%= GetLoginPostBack() %>;
}
</script>

The final javascript will be rendered like this.

<script language="javascript">
function btnLogin_Click() {
  __doPostBack('btnLogin','');
}
</script>

Now you can use "btnLogin_Click()" from your javascript to submit the button click to the server.

Use the where command. The first result in the list is the one that will execute.

C:\> where notepad
C:\Windows\System32\notepad.exe
C:\Windows\notepad.exe

According to this blog post, where.exe is included with Windows Server 2003 and later, so this should just work with Vista, Win 7, et al.

On Linux, the equivalent is the which command, e.g. which ssh.

I solved it this way.

ssh -vvv <username>@github.com to see github IP.

Then opened browser and opened github via IP to find it was an issue with firewall.

If you have a table with millions of rows and care about the performance, this could be a better answer:

SELECT * FROM Table1
WHERE (ABS(CAST(
  (BINARY_CHECKSUM
  (keycol1, NEWID())) as int))
  % 100) < 10

https://msdn.microsoft.com/en-us/library/cc441928.aspx

Use the built in collection methods contain and find, which will search by primary ids (instead of array keys). Example:

if ($model->collection->contains($primaryId)) {
    var_dump($model->collection->find($primaryId);
}

contains() actually just calls find() and checks for null, so you could shorten it down to:

if ($myModel = $model->collection->find($primaryId)) {
    var_dump($myModel);
}

You shouldn't write your own browser-detection code - it's been done many times before. Use Modernizr to detect independent browser features instead. It's better to detect the various features than to detect entire browsers because various browsers may support different set of features and those features may even change through various versions of the same browser. If you detect the presence of a given feature, your code will likely work better in more browsers. This is especially true for the various mobile browsers.

When you run Modernizr, it'll update your HEAD element's class attribute so that it lists the various features of the browser that you're using - you can then use Javascript to query the attribute and decide what to do if a feature is present (or missing).

It don't create normally; you need to add it by yourself.

After adding Global.asax by

• Right clicking your website -> Add New Item -> Global Application Class -> Add

You need to add a class

• Right clicking App_Code -> Add New Item -> Class -> name it Global.cs -> Add

Inherit the newly generated by System.Web.HttpApplication and copy all the method created Global.asax to Global.cs and also add an inherit attribute to the Global.asax file.

Your Global.asax will look like this: -

<%@ Application Language="C#" Inherits="Global" %>

Your Global.cs in App_Code will look like this: -

public class Global : System.Web.HttpApplication
{
    public Global()
    {
        //
        // TODO: Add constructor logic here
        //
    }

    void Application_Start(object sender, EventArgs e)
    {
        // Code that runs on application startup

    }
    /// Many other events like begin request...e.t.c, e.t.c
}

Views are all drawn on the same GUI thread which is also used for all user interaction.

So if you need to update GUI rapidly or if the rendering takes too much time and affects user experience then use SurfaceView.

If you use gitlab-ci / gitlab-runners you get that error if you don't have permissions to access /var/run/docker.sock.

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock

To solve the problem:

sudo usermod -aG docker gitlab-runner

Verify with:

sudo -u gitlab-runner -H docker info

Hope that helps.

The quick and dirty way, you can view the available environment variables from the below link.

For email templates, inline CSS is the properly used method to style:

<thead>
    <tr style="color: #fff; background: black;">
        <th>Header 1</th>
        <th>Header 2</th>
        <th>Header 3</th>
    </tr>
</thead>

Create A Shortcut That Opens The Command Prompt & Runs A Command:

Yes! You can create a shortcut to cmd.exe with a command specified after it. Alternatively you could create a batch script, if your goal is just to have a clickable way to run commands.

Steps:

1. Right click on some empty space in Explorer, and in the context menu go to "New/Shortcut".

2. When prompted to enter a location put either:

"C:\Windows\System32\cmd.exe /k your-command" This will run the command and keep (/k) the command prompt open after.

or

"C:\Windows\System32\cmd.exe /c your-command" This will run the command and the close (/c) the command prompt.

Notes:

• Tested, and working on Windows 8 - Core X86-64 September 12 2014

• If you want to have more than one command, place an "&" symbol in between them. For example: "C:\Windows\System32\cmd.exe /k command1 & command2".

This might be work for you

The issue for me was the type I was using was in objective-c in a swift project and I had forgotten to import the type's objective-c header file in the bridging header file

It may be easier to use XPath to locate the nodes that you wish to delete. This stackoverflow thread might give you some ideas.

In your case you will find the four nodes that you want using this expression:

XmlDocument doc = new XmlDocument();
doc.Load(fileName);
XmlNodeList nodes = doc.SelectNodes("//Setting[@name='File1']");

I experienced this issue when I tried to update a Hot Towel Project from the project template and when I created an empty project and installed HotTowel via nuget in VS 2012 as of 10/23/2013.

To fix, I updated via Nuget the Web Api Web Host and Web API packages to 5.0, the current version in NuGet at the moment (10/23/2013).

I then added the binding directs:

You could look into the 'Content-Type' header to see that it is correct?

response.header['Content-Type'].should include 'text/javascript'

Here's how you do it with ajax.

$("#updatebtn").click(function () {
    $("#updatebtn").prop("disabled", true);
    urlToHandler = 'update.ashx';
            jsonData = data;
            $.ajax({
                url: urlToHandler,
                data: jsonData,
                dataType: 'json',
                type: 'POST',
                contentType: 'application/json',
                success: function (data) {
                    $("#lbl").html(data.response);
                    $("#updatebtn").prop("disabled", false);
                    //setAutocompleteData(data.response);
                },
                error: function (data, status, jqXHR) {
                    alert('There was an error.');
                    $("#updatebtn").prop("disabled", false);
                }
            }); // end $.ajax

Do you want to iterate over characters or words?

For words, you'll have to split the words first, such as

for index, word in enumerate(loopme.split(" ")):
    print "CURRENT WORD IS", word, "AT INDEX", index

This prints the index of the word.

For the absolute character position you'd need something like

chars = 0
for index, word in enumerate(loopme.split(" ")):
    print "CURRENT WORD IS", word, "AT INDEX", index, "AND AT CHARACTER", chars
    chars += len(word) + 1

Heredoc's are a great alternative to quoted strings because of increased readability and maintainability. You don't have to escape quotes and (good) IDEs or text editors will use the proper syntax highlighting.

A very common example: echoing out HTML from within PHP:

$html = <<<HTML
  <div class='something'>
    <ul class='mylist'>
      <li>$something</li>
      <li>$whatever</li>
      <li>$testing123</li>
    </ul>
  </div>
HTML;

// Sometime later
echo $html;

It is easy to read and easy to maintain.

The alternative is echoing quoted strings, which end up containing escaped quotes and IDEs aren't going to highlight the syntax for that language, which leads to poor readability and more difficulty in maintenance.

Updated answer for Your Common Sense

Of course you wouldn't want to see an SQL query highlighted as HTML. To use other languages, simply change the language in the syntax:

$sql = <<<SQL
       SELECT * FROM table
SQL;

Mark,

I believe you want to use android:scaleType="fitXY".

@Nazar Medeiros - Your solution uses passport with Express. I am not using passport, just express-jwt. I might be doing something wrong, but when a user logs in, the token needs to return to the client side. From what I have found so far, this means we have to return a json with the token and therefor cannot call redirect. Is there something I am missing there?

To get around this, I simply return the token, store it in my cookies and then make a ajax GET request (with the valid token). When that ajax call returns I replace the body's html with the returned HTML. This is probably not the right way to do it, but I can't find a better way. Here is my JQuery JavaScript code.

function loginUser(){
  $.post("/users/login", {
    username: $( '#login_input_username' ).val(),
   password: $( '#login_input_password' ).val()
 }).done(function(res){
    document.cookie = "token = " + res.token;
    redirectToHome();
  })
}

function redirectToHome(){
  var settings = {
    "async": true,
    "crossDomain": true,
    "url": "/home",
    "type": "GET",
    "headers": {
      "authorization": "Bearer " + getCookie('token'),
      "cache-control": "no-cache"
    }
  }

  $.ajax(settings).done(function (response) {
    $('body').replaceWith(response);
  });
}

function getCookie(cname) {
    var name = cname + "=";
    var decodedCookie = decodeURIComponent(document.cookie);
    var ca = decodedCookie.split(';');
    for(var i = 0; i <ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') {
            c = c.substring(1);
        }
        if (c.indexOf(name) == 0) {
            return c.substring(name.length, c.length);
        }
    }
    return "";
}

All the answers here use JSON objects. This gave us problems with the $this->input->post() methods of our Codeigniter controllers. The CI_Controller cannot read JSON directly. We used this method to do it WITHOUT JSON

func postRequest() {
    // Create url object
    guard let url = URL(string: yourURL) else {return}

    // Create the session object
    let session = URLSession.shared

    // Create the URLRequest object using the url object
    var request = URLRequest(url: url)

    // Set the request method. Important Do not set any other headers, like Content-Type
    request.httpMethod = "POST" //set http method as POST

    // Set parameters here. Replace with your own.
    let postData = "param1_id=param1_value&param2_id=param2_value".data(using: .utf8)
    request.httpBody = postData

    // Create a task using the session object, to run and return completion handler
    let webTask = session.dataTask(with: request, completionHandler: {data, response, error in
    guard error == nil else {
        print(error?.localizedDescription ?? "Response Error")
        return
    }
    guard let serverData = data else {
        print("server data error")
        return
    }
    do {
        if let requestJson = try JSONSerialization.jsonObject(with: serverData, options: .mutableContainers) as? [String: Any]{
            print("Response: \(requestJson)")
        }
    } catch let responseError {
        print("Serialisation in error in creating response body: \(responseError.localizedDescription)")
        let message = String(bytes: serverData, encoding: .ascii)
        print(message as Any)
    }

    // Run the task
    webTask.resume()
}

Now your CI_Controller will be able to get param1 and param2 using $this->input->post('param1') and $this->input->post('param2')

There is no need to use angular http, you can get with js native functions

// you will ned this function to fetch the image blob._x000D_
async function getImage(url, fileName) {_x000D_
     // on the first then you will return blob from response_x000D_
    return await fetch(url).then(r => r.blob())_x000D_
    .then((blob) => { // on the second, you just create a file from that blob, getting the type and name that intend to inform_x000D_
         _x000D_
        return new File([blob], fileName+'.'+   blob.type.split('/')[1]) ;_x000D_
    });_x000D_
}_x000D_
_x000D_
// example url_x000D_
var url = 'https://img.freepik.com/vetores-gratis/icone-realista-quebrado-vidro-fosco_1284-12125.jpg';_x000D_
_x000D_
// calling the function_x000D_
getImage(url, 'your-name-image').then(function(file) {_x000D_
_x000D_
    // with file reader you will transform the file in a data url file;_x000D_
    var reader = new FileReader();_x000D_
    reader.readAsDataURL(file);_x000D_
    reader.onloadend = () => {_x000D_
    _x000D_
    // just putting the data url to img element_x000D_
        document.querySelector('#image').src = reader.result ;_x000D_
    }_x000D_
})

<img src="" id="image"/>

You seem a bit confused as to how numpy arrays work behind the scenes. Each item in an array must be the same size.

The string representation of a float doesn't work this way. For example, repr(1.3) yields '1.3', but repr(1.33) yields '1.3300000000000001'.

A accurate string representation of a floating point number produces a variable length string.

Because numpy arrays consist of elements that are all the same size, numpy requires you to specify the length of the strings within the array when you're using string arrays.

If you use x.astype('str'), it will always convert things to an array of strings of length 1.

For example, using x = np.array(1.344566), x.astype('str') yields '1'!

You need to be more explict and use the '|Sx' dtype syntax, where x is the length of the string for each element of the array.

For example, use x.astype('|S10') to convert the array to strings of length 10.

Even better, just avoid using numpy arrays of strings altogether. It's usually a bad idea, and there's no reason I can see from your description of your problem to use them in the first place...

     string ImagePath = "";

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(ImagePath);
        string a = "";
        try
        {
            HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
            Stream receiveStream = response.GetResponseStream();
            if (receiveStream.CanRead)
            { a = "OK"; }
        }

        catch { }

First, an apk file is just a modified jar file. So the real question is can they decompile the dex files inside. The answer is sort of. There are already disassemblers, such as dedexer and smali. You can expect these to only get better, and theoretically it should eventually be possible to decompile to actual Java source (at least sometimes). See the previous question decompiling DEX into Java sourcecode.

What you should remember is obfuscation never works. Choose a good license and do your best to enforce it through the law. Don't waste time with unreliable technical measures.

All i needed were the correct credentials. while deploying to a web app, i had to go to Deployment Center, Deployment Credentials. And then use either the App Credentials or create User Credentials. After this, delete the cached credentials on the local machine (windows: Control Panel\User Accounts\Credential Manager). run "git push webapp master:master" again, enter either of the Deployment Credentials. This worked for me.

Python 3.6 Timings

Here are the timing results using Python 3.6.8. Keep in mind these times are relative to one another, not absolute.

I stuck to only doing shallow copies, and also added some new methods that weren't possible in Python2, such as list.copy() (the Python3 slice equivalent) and two forms of list unpacking (*new_list, = list and new_list = [*list]):

METHOD                  TIME TAKEN
b = [*a]                2.75180600000021
b = a * 1               3.50215399999990
b = a[:]                3.78278899999986  # Python2 winner (see above)
b = a.copy()            4.20556500000020  # Python3 "slice equivalent" (see above)
b = []; b.extend(a)     4.68069800000012
b = a[0:len(a)]         6.84498999999959
*b, = a                 7.54031799999984
b = list(a)             7.75815899999997
b = [i for i in a]      18.4886440000000
b = copy.copy(a)        18.8254879999999
b = []
for item in a:
  b.append(item)        35.4729199999997

We can see the Python2 winner still does well, but doesn't edge out Python3 list.copy() by much, especially considering the superior readability of the latter.

The dark horse is the unpacking and repacking method (b = [*a]), which is ~25% faster than raw slicing, and more than twice as fast as the other unpacking method (*b, = a).

b = a * 1 also does surprisingly well.

Note that these methods do not output equivalent results for any input other than lists. They all work for sliceable objects, a few work for any iterable, but only copy.copy() works for more general Python objects.

Here is the testing code for interested parties (Template from here):

import timeit

COUNT = 50000000
print("Array duplicating. Tests run", COUNT, "times")
setup = 'a = [0,1,2,3,4,5,6,7,8,9]; import copy'

print("b = list(a)\t\t", timeit.timeit(stmt='b = list(a)', setup=setup, number=COUNT))
print("b = copy.copy(a)\t", timeit.timeit(stmt='b = copy.copy(a)', setup=setup, number=COUNT))
print("b = a.copy()\t\t", timeit.timeit(stmt='b = a.copy()', setup=setup, number=COUNT))
print("b = a[:]\t\t", timeit.timeit(stmt='b = a[:]', setup=setup, number=COUNT))
print("b = a[0:len(a)]\t\t", timeit.timeit(stmt='b = a[0:len(a)]', setup=setup, number=COUNT))
print("*b, = a\t\t\t", timeit.timeit(stmt='*b, = a', setup=setup, number=COUNT))
print("b = []; b.extend(a)\t", timeit.timeit(stmt='b = []; b.extend(a)', setup=setup, number=COUNT))
print("b = []; for item in a: b.append(item)\t", timeit.timeit(stmt='b = []\nfor item in a:  b.append(item)', setup=setup, number=COUNT))
print("b = [i for i in a]\t", timeit.timeit(stmt='b = [i for i in a]', setup=setup, number=COUNT))
print("b = [*a]\t\t", timeit.timeit(stmt='b = [*a]', setup=setup, number=COUNT))
print("b = a * 1\t\t", timeit.timeit(stmt='b = a * 1', setup=setup, number=COUNT))

For 2005 and later, these will both give what you're looking for.

SELECT name FROM sys.schemas
SELECT SCHEMA_NAME FROM INFORMATION_SCHEMA.SCHEMATA

For 2000, this will give a list of the databases in the instance.

SELECT * FROM INFORMATION_SCHEMA.SCHEMATA

That's the "backward incompatability" noted in @Adrift's answer.

In SQL Server 2000 (and lower), there aren't really "schemas" as such, although you can use roles as namespaces in a similar way. In that case, this may be the closest equivalent.

SELECT * FROM sysusers WHERE gid <> 0

Use iText's HTMLWorker

Example

Angular 1.3 provides $watchGroup specifically for this purpose:

https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$watchGroup

This seems to provide the same ultimate result as a standard $watch on an array of expressions. I like it because it makes the intention clearer in the code.

Keep the jar files under web-inf lib incase you included jar and it is not able to identify .

It worked in my case where everything was ok but it was not able to load the driver class.

Either you set LDAP_DOMAIN variable or you misconfigured it. Jump inside of ldap machine/container and run:

slapcat > backup.ldif

If it fails, check punctuation, quotes etc while you assigned variable "LDAP_DOMAIN" Otherwise you will find answer inside on backup.ldif file.

When you have three columns : first_name, last_name, mid_name:

SELECT CASE 
    WHEN mid_name IS NULL OR TRIM(mid_name) ='' THEN
        CONCAT_WS( " ", first_name, last_name ) 
    ELSE 
        CONCAT_WS( " ", first_name, mid_name, last_name ) 
    END 
FROM USER;

String start_dt = "2011-01-31";

DateFormat parser = new SimpleDateFormat("yyyy-MM-dd"); 
Date date = (Date) parser.parse(start_dt);

DateFormat formatter = new SimpleDateFormat("MM-dd-yyyy"); 
System.out.println(formatter.format(date));

Prints: 01-31-2011

You can access the inactive tags array with (assuming $myArray contains the array)

$myArray['inactiveTags'];

Your question doesn't seem to go beyond accessing the contents of the inactiveTags key so I can only speculate with what your final goal is.

The first key:value pair in the inactiveTags array is

array ('195' => array(
                 'id' => 195, 
                 'tag' => 'auto')
      )

To access the tag value, you would use

$myArray['inactiveTags'][195]['tag']; // auto

If you want to loop through each inactiveTags element, I would suggest:

foreach($myArray['inactiveTags'] as $value) {
  print $value['id'];
  print $value['tag'];
}

This will print all the id and tag values for each inactiveTag

The easiest way is to add the:

$('#ID').css("height", $(document).height());

after the correct page height is determined by the browser. If the document height is changed once more re-run the above code.

The display:table family of CSS properties is mostly there so that HTML tables can be defined in terms of them. Because they're so intimately linked to a specific tag structure, they don't see much use beyond that.

If you were going to use these properties in your page, you would need a tag structure that closely mimicked that of tables, even though you weren't actually using the <table> family of tags. A minimal version would be a single container element (display:table), with direct children that can all be represented as rows (display:table-row), which themselves have direct children that can all be represented as cells (display:table-cell). There are other properties that let you mimic other tags in the table family, but they require analogous structures in the HTML. Without this, it's going to be very hard (if not impossible) to make good use of these properties.

The accepted way to rename a table in Laravel 4 is to use the Schema builder. So you would want to do:

Schema::rename('photos', 'images');

From http://laravel.com/docs/4.2/schema#creating-and-dropping-tables

If you really want to write out a raw SQL query yourself, you can always do:

DB::statement('alter table photos rename to images');

Note: Laravel's DB class also supports running raw SQL select, insert, update, and delete queries, like:

$users = DB::select('select id, name from users');

For more info, see http://laravel.com/docs/4.2/database#running-queries.

essentially the shadow is the box shape just offset behind the actual box. in order to hide portions of the shadow, you need to create additional divs and set their z-index above the shadowed box so that the shadow is not visible.

If you'd like to have extremely specific control over your shadows, build them as images and created container divs with the right amount of padding and margins.. then use the png fix to make sure the shadows render properly in all browsers

memory mapping is not only used to map files into memory but is also a tool to request RAM from kernel. These are those inode 0 entries - your stack, heap, bss segments and more

Looks like for both of your objects (inside the array), you have an extra closing brace after "Longitude".

The best that I've been able to do is

$(this).closest('.modal').modal('toggle');

This gets the modal holding the DOM object you triggered the event on (guessing you're clicking a button). Gets the closest parent '.modal' and toggles it. Obviously only works because it's inside the modal you clicked.

You can however do this:

$(".modal:visible").modal('toggle');

This gets the modal that is displaying (since you can only have one open at a time), and triggers the 'toggle' This would not work without ":visible"

In Bootstrap 3 I've added a table-no-border class

.table-no-border>thead>tr>th, 
.table-no-border>tbody>tr>th, 
.table-no-border>tfoot>tr>th, 
.table-no-border>thead>tr>td, 
.table-no-border>tbody>tr>td, 
.table-no-border>tfoot>tr>td {
  border-top: none; 
}

I found another strange reason and i thought maybe another developer confused as me. I did run install.bat that created to install my service in developer Command Prompt of VS2010 but my service generated in VS2012. it was going to this error and drives me to crazy but i try VS2012 Developer Command Prompt tools and everything gone to be OK. I don't no why but my problem was solved. so you can test it and if anyone know reason of that please share with us. Thanks.

This is a bit of an old question, but I thought I would contribute my 2 cents anyway since this thread came up in conversation today.

This doesn't exactly answer why is there no const? but how to make your classes immutable. (Unfortunately I have not enough reputation yet to post as a comment to the accepted answer)

The way to guarantee immutability on an object is to design your classes more carefully to be immutable. This requires a bit more care than a mutable class.

This goes back to Josh Bloch's Effective Java Item 15 - Minimize Mutability. If you haven't read the book, pick up a copy and read it over a few times I guarantee it will up your figurative "java game".

In item 15 Bloch suggest that you should limit the mutability of classes to ensure the object's state.

To quote the book directly:

An immutable class is simply a class whose instances cannot be modified. All of the information contained in each instance is provided when it is created and is fixed for the lifetime of the object. The Java platform libraries contain many immutable classes, including String, the boxed primitive classes, and BigInte- ger and BigDecimal. There are many good reasons for this: Immutable classes are easier to design, implement, and use than mutable classes. They are less prone to error and are more secure.

Bloch then describes how to make your classes immutable, by following 5 simple rules:

1. Don’t provide any methods that modify the object’s state (i.e., setters, aka mutators)
2. Ensure that the class can’t be extended (this means declaring the class itself as final).
3. Make all fields final.
4. Make all fields private.
5. Ensure exclusive access to any mutable components. (by making defensive copies of the objects)

For more details I highly recommend picking up a copy of the book.

I tried the accepted solution and it didn't work for me. I use the browser debugger and found out the actual height that should be used is the clientHeight BUT you have to put this into the updated() hook for the whole solution to work.

data(){
return {
  conversation: [
    {
    }
  ]
 },
mounted(){
 EventBus.$on('msg-ctr--push-msg-in-conversation', textMsg => {
  this.conversation.push(textMsg)
  // Didn't work doing scroll here
 })
},
updated(){              <=== PUT IT HERE !!
  var elem = this.$el
  elem.scrollTop = elem.clientHeight;
},

As described in this answer, you can easily create your own selector for hasText. This allows you to find the option with $('#test').find('option:hastText("B")').val();

Here's the hasText method I added:

 if( ! $.expr[':']['hasText'] ) {
     $.expr[':']['hasText'] = function( node, index, props ) {
       var retVal = false;
       // Verify single text child node with matching text
       if( node.nodeType == 1 && node.childNodes.length == 1 ) {
         var childNode = node.childNodes[0];
         retVal = childNode.nodeType == 3 && childNode.nodeValue === props[3];
       }
       return retVal;
     };
  }

I got this error message with vs2015, ssdt 14.1.xxx, ssrs. For me I think it was something different than described above with a 2 column, same name problem. I added this report, then deleted the report, then when I tried to add the query back in the ssrs wizard I got this message, " An error occurred while the query design method was being saved :invalid object name: tablename" . where tablename was the table on the query the wizard was reading. I tried cleaning the project, I tried rebuilding the project. In my opinion Microsoft isn't completing cleaning out the report when you delete it and as long as you try to add the original query back it won't add. The way I was able to fix it was to create the ssrs report in a whole new project (obviously nothing wrong with the query) and save it off to the side. Then I reopened my original ssrs project, right clicked on Reports, then Add, then add Existing Item. The report added back in just fine with no name conflict.

rebellion's answer above won't actually work, because to CSS, 'background-position' is actually shorthand for 'background-position-x' and 'background-position-y' so the correct version of his code would be:

$(document).ready(function(){
    $('#submenu li').hover(function(){
        $('#carousel').css('background-position-x', newValueX);
        $('#carousel').css('background-position-y', newValue);
    }, function(){
        $('#carousel').css('background-position-x', oldValueX);
        $('#carousel').css('background-position-y', oldValueY);
    });
});

It took about 4 hours of banging my head against it to come to that aggravating realization.

Here is my solution with C# in Unity.

private bool _isPointOnLine( Vector2 ptLineStart, Vector2 ptLineEnd, Vector2 ptPoint )
{
    bool bRes = false;
    if((Mathf.Approximately(ptPoint.x, ptLineStart.x) || Mathf.Approximately(ptPoint.x, ptLineEnd.x)))
    {
        if(ptPoint.y > ptLineStart.y && ptPoint.y < ptLineEnd.y)
        {
            bRes = true;
        }
    }
    else if((Mathf.Approximately(ptPoint.y, ptLineStart.y) || Mathf.Approximately(ptPoint.y, ptLineEnd.y)))
    {
        if(ptPoint.x > ptLineStart.x && ptPoint.x < ptLineEnd.x)
        {
            bRes = true;
        }
    }
    return bRes;
}

Looking at all those calculations, it may is helpful that most of the Units (Hours, Minutes, etc.) have a .toFooPart() convenience method.

E.g.

Duration.ofMinutes(110L).toMinutesPart() == 50

Read: the minutes elapsed to the next value of the parent unit (Hour).

for xcode 8 i did this and it worked:

If you want to do it from code behind, try this:

System.Web.UI.ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "AlertBox", "alert('Message');", true);

Under Windows for me this works:

virtualenv --python=c:\Python25\python.exe envname

without the python.exe I got WindowsError: [Error 5] Access is denied I have Python2.7.1 installed with virtualenv 1.6.1, and I wanted python 2.5.2.

If you want to skip running and compiling tests:

mvn -Dmaven.test.skip=true install

If you want to compile but not run tests:

mvn install -DskipTests

with virtual env activate

export FLASK_DEBUG=true

you can configure

export FLASK_APP=app.py  # run.py
export FLASK_ENV = "development"

to start

flask run

the result

 * Environment: development
 * Debug mode: on
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
 * Restarting with stat
 * Debugger is active!
 * Debugger PIN: xxx-xxx-xxx

and if you change

export FLASK_DEBUG=false

 * Environment: development
 * Debug mode: off
 * Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

You just need to add 'table-layout: fixed;'

.table {
   display: table;
   height: 100px;
   width: 100%;
   table-layout: fixed;
}

It worth to say that discussed topic is documented in RFC 2397 - The "data" URL scheme (https://tools.ietf.org/html/rfc2397)

Because of this PHP has a native way to handle such data - "data: stream wrapper" (http://php.net/manual/en/wrappers.data.php)

So you can easily manipulate your data with PHP streams:

$data = 'data:image/gif;base64,R0lGODlhEAAOALMAAOazToeHh0tLS/7LZv/0jvb29t/f3//Ub//ge8WSLf/rhf/3kdbW1mxsbP//mf///yH5BAAAAAAALAAAAAAQAA4AAARe8L1Ekyky67QZ1hLnjM5UUde0ECwLJoExKcppV0aCcGCmTIHEIUEqjgaORCMxIC6e0CcguWw6aFjsVMkkIr7g77ZKPJjPZqIyd7sJAgVGoEGv2xsBxqNgYPj/gAwXEQA7';

$source = fopen($data, 'r');
$destination = fopen('image.gif', 'w');

stream_copy_to_stream($source, $destination);

fclose($source);
fclose($destination);

Adding to what @Shog9 posted, you can also restrict dates individually in the beforeShowDay: callback function.

You supply a function that takes a date and returns a boolean array:

"$(".selector").datepicker({ beforeShowDay: nationalDays}) 
natDays = [[1, 26, 'au'], [2, 6, 'nz'], [3, 17, 'ie'], [4, 27, 'za'], 
[5, 25, 'ar'], [6, 6, 'se'], [7, 4, 'us'], [8, 17, 'id'], [9, 7, 
'br'], [10, 1, 'cn'], [11, 22, 'lb'], [12, 12, 'ke']]; 
function nationalDays(date) { 
    for (i = 0; i < natDays.length; i++) { 
      if (date.getMonth() == natDays[i][0] - 1 && date.getDate() == 
natDays[i][1]) { 
        return [false, natDays[i][2] + '_day']; 
      } 
    } 
  return [true, '']; 
}
