In git version 2.14.3,

You can remove upstream using

git branch --unset-upstream

The above command will also remove the tracking stream branch, hence if you want to rebase from repository you have use

git rebase origin master 

instead of git pull --rebase

The other answers so far create new commits that undo what is in older commits. It is possible to go back and "change history" as it were, but this can be a bit dangerous. You should only do this if the commit you're changing has not been pushed to other repositories.

The command you're looking for is git rebase --interactive

If you want to change HEAD~3, the command you want to issue is git rebase --interactive HEAD~4. This will open a text editor and allow you to specify which commits you want to change.

Practice on a different repository before you try this with something important. The man pages should give you all the rest of the information you need.

You want to use Apache's CloseShieldInputStream:

This is a wrapper that will prevent the stream from being closed. You'd do something like this.

InputStream is = null;

is = getStream(); //obtain the stream 
CloseShieldInputStream csis = new CloseShieldInputStream(is);

// call the bad function that does things it shouldn't
badFunction(csis);

// happiness follows: do something with the original input stream
is.read();

make sure to change in ajax call

async: true,
type: "GET",
dataType: "html",

As the other answers state there is no way getting query string parameters using servlet api.

So, I think the best way to get query parameters is parsing the query string yourself. ( It is more complicated iterating over parameters and checking if query string contains the parameter)

I wrote below code to get query string parameters. Using apache StringUtils and ArrayUtils which supports CSV separated query param values as well.

Example: username=james&username=smith&password=pwd1,pwd2 will return

password : [pwd1, pwd2] (length = 2)

username : [james, smith] (length = 2)

public static Map<String, String[]> getQueryParameters(HttpServletRequest request) throws UnsupportedEncodingException {
    Map<String, String[]> queryParameters = new HashMap<>();
    String queryString = request.getQueryString();
    if (StringUtils.isNotEmpty(queryString)) {
        queryString = URLDecoder.decode(queryString, StandardCharsets.UTF_8.toString());
        String[] parameters = queryString.split("&");
        for (String parameter : parameters) {
            String[] keyValuePair = parameter.split("=");
            String[] values = queryParameters.get(keyValuePair[0]);
            //length is one if no value is available.
            values = keyValuePair.length == 1 ? ArrayUtils.add(values, "") :
                    ArrayUtils.addAll(values, keyValuePair[1].split(",")); //handles CSV separated query param values.
            queryParameters.put(keyValuePair[0], values);
        }
    }
    return queryParameters;
}

Imagine a friend is leaving your house, and you tell her "Call me when you get home so that I know you arrived safely"; that is (literally) a call back. That's what a callback function is, regardless of language. You want some procedure to pass control back to you when it has completed some task, so you give it a function to use to call back to you.

In Python, for example,

grabDBValue( (lambda x: passValueToGUIWindow(x) ))

grabDBValue could be written to only grab a value from a database and then let you specify what to actually do with the value, so it accepts a function. You don't know when or if grabDBValue will return, but if/when it does, you know what you want it to do. Here, I pass in an anonymous function (or lambda) that sends the value to a GUI window. I could easily change the behavior of the program by doing this:

grabDBValue( (lambda x: passToLogger(x) ))

Callbacks work well in languages where functions are first class values, just like the usual integers, character strings, booleans, etc. In C, you can "pass" a function around by passing around a pointer to it and the caller can use that; in Java, the caller will ask for a static class of a certain type with a certain method name since there are no functions ("methods," really) outside of classes; and in most other dynamic languages you can just pass a function with simple syntax.

Protip:

In languages with lexical scoping (like Scheme or Perl) you can pull a trick like this:

my $var = 2;
my $val = someCallerBackFunction(sub callback { return $var * 3; });
# Perlistas note: I know the sub doesn't need a name, this is for illustration

$val in this case will be 6 because the callback has access to the variables declared in the lexical environment where it was defined. Lexical scope and anonymous callbacks are a powerful combination warranting further study for the novice programmer.

On RHEL 6 this worked:

umount -f -a -t cifs -l 

You can also try to use get(), for example:

connection = manager.connect.get("I2Cx")

which won't raise a KeyError in case the key doesn't exist.

You may also use second argument to specify the default value, if the key is not present.

As everyone else has said, instantiate the object before throwing it.

Just wanted to add one bit; it's incredibly uncommon to throw a RuntimeException. It would be normal for code in the API to throw a subclass of this, but normally, application code would throw Exception, or something that extends Exception but not RuntimeException.

And in retrospect, I missed adding the reason why you use Exception instead of RuntimeException; @Jay, in the comment below, added in the useful bit. RuntimeException isn't a checked exception;

• The method signature doesn't have to declare that a RuntimeException may be thrown.
• Callers of that method aren't required to catch the exception, or acknowlege it in any way.
• Developers who try to later use your code won't anticipate this problem unless they look carefully, and it will increase the maintenance burden of the code.

While you need result for date as desc

$results = Project::latest('created_at')->get();

git checkout <target_branch>
git checkout <source_branch> <file_path>

Please check if postgres(or any other database service) is running properly.

Here, I wrote something similar to what u need:

    inputBoxNumberEt.setText(".     ");
    inputBoxNumberEt.setSelection(inputBoxNumberEt.getText().length());
    inputBoxNumberEt.addTextChangedListener(new TextWatcher() {

        boolean ignoreChange = false;

        @Override
        public void afterTextChanged(Editable s) {
        }

        @Override
        public void beforeTextChanged(CharSequence s, int start,
                                      int count, int after) {
        }

        @Override
        public void onTextChanged(CharSequence s, int start,
                                  int before, int count) {
            if (!ignoreChange) {
                String string = s.toString();
                string = string.replace(".", "");
                string = string.replace(" ", "");
                if (string.length() == 0)
                    string = ".     ";
                else if (string.length() == 1)
                    string = ".  " + string;
                else if (string.length() == 2)
                    string = "." + string;
                else if (string.length() > 2)
                    string = string.substring(0, string.length() - 2) + "." + string.substring(string.length() - 2, string.length());
                ignoreChange = true;
                inputBoxNumberEt.setText(string);
                inputBoxNumberEt.setSelection(inputBoxNumberEt.getText().length());
                ignoreChange = false;
            }
        }
    });

I recommend using a cache-buster in the wsdl url.

In our apps we use a SVN Revision id in the wsdl url so the client immediately knows of changing structures. This works on our app because, everytime we change the server-side, we also need to adjust the client accordingly.

$client = new SoapClient('http://somewhere.com/?wsdl&rev=$Revision$');

This requires svn to be configured properly. Not on all repositories this is enabled by default.

In case you are not responsible for both components (server,client) or you don't use SVN you may find another indicator which can be utilised as a cache-buster in your wsdl url.

Technically speaking the answer is correct, but there is a potential problem remaining. string test = rb.SelectedValue is an object and while this implicit cast works. It may not work correction if you were sending it to another method (and granted this may depend on the version of framework, I am unsure) it may not recognize the value.

string test = rb.SelectedValue;  //May work fine
SomeMethod(rb.SelectedValue);

where SomeMethod is expecting a string may not.

Sadly the rb.SelectedValue.ToString(); can save a few unexpected issues.

1. 'sender' is called object which has some action perform on some control

2. 'event' its having some information about control which has some behavoiur and identity perform by some user.when action will generate by occuring for event add it keep within array is called event agrs

Well I think the simplest and fastest solution here would be just to:

StringBuilder sb = new StringBuilder();

using (var writer = XmlWriter.Create(sb, settings))
{
    ... // Whatever code you have/need :)

    sb = sb.Replace("encoding=\"utf-16\"", "encoding=\"utf-8\""); //Or whatever uft you want/use.
    //Before you finally save it:
    File.WriteAllText("path\\dataName.xml", sb.ToString());
}

Issue a forced push with the command:

git push -f origin master

Backup over ssh with password using temporary .pgpass credentials and push to S3:

#!/usr/bin/env bash
cd "$(dirname "$0")"

DB_HOST="*******.*********.us-west-2.rds.amazonaws.com"
DB_USER="*******"
SSH_HOST="[email protected]_domain.com"
BUCKET_PATH="bucket_name/backup"

if [ $# -ne 2 ]; then
    echo "Error: 2 arguments required"
    echo "Usage:"
    echo "  my-backup-script.sh <DB-name> <password>"
    echo "  <DB-name> = The name of the DB to backup"
    echo "  <password> = The DB password, which is also used for GPG encryption of the backup file"
    echo "Example:"
    echo "  my-backup-script.sh my_db my_password"
    exit 1
fi

DATABASE=$1
PASSWORD=$2

echo "set remote PG password .."
echo "$DB_HOST:5432:$DATABASE:$DB_USER:$PASSWORD" | ssh "$SSH_HOST" "cat > ~/.pgpass; chmod 0600 ~/.pgpass"
echo "backup over SSH and gzip the backup .."
ssh "$SSH_HOST" "pg_dump -U $DB_USER -h $DB_HOST -C --column-inserts $DATABASE" | gzip > ./tmp.gz
echo "unset remote PG password .."
echo "*********" | ssh "$SSH_HOST" "cat > ~/.pgpass"
echo "encrypt the backup .."
gpg --batch --passphrase "$PASSWORD" --cipher-algo AES256 --compression-algo BZIP2 -co "$DATABASE.sql.gz.gpg" ./tmp.gz

# Backing up to AWS obviously requires having your credentials to be set locally
# EC2 instances can use instance permissions to push files to S3
DATETIME=`date "+%Y%m%d-%H%M%S"`
aws s3 cp ./"$DATABASE.sql.gz.gpg" s3://"$BUCKET_PATH"/"$DATABASE"/db/"$DATETIME".sql.gz.gpg
# s3 is cheap, so don't worry about a little temporary duplication here
# "latest" is always good to have because it makes it easier for dev-ops to use
aws s3 cp ./"$DATABASE.sql.gz.gpg" s3://"$BUCKET_PATH"/"$DATABASE"/db/latest.sql.gz.gpg

echo "local clean-up .."
rm ./tmp.gz
rm "$DATABASE.sql.gz.gpg"

echo "-----------------------"
echo "To decrypt and extract:"
echo "-----------------------"
echo "gpg -d ./$DATABASE.sql.gz.gpg | gunzip > tmp.sql"
echo

Just substitute the first couple of config lines with whatever you need - obviously. For those not interested in the S3 backup part, take it out - obviously.

This script deletes the credentials in .pgpass afterward because in some environments, the default SSH user can sudo without a password, for example an EC2 instance with the ubuntu user, so using .pgpass with a different host account in order to secure those credential, might be pointless.

Code I use myself:

std::string prefix = "-param=";
std::string argument = argv[1];
if(argument.substr(0, prefix.size()) == prefix) {
    std::string argumentValue = argument.substr(prefix.size());
}

$result = mysqli_query($con,"SELECT `note` FROM `glogin_users` WHERE email = '".$email."'");
while($row = mysqli_fetch_array($result))
echo $row['note'];

I have the following function in my .bashrc file - it looks up the errno value from the header files (can be either /usr/include/errno.h, /usr/include/linux/errno.h, etc., etc.)

It works if header files are installed on the machine;-)

Usually the header file have an error + next comes the explanation in the comment; something of the following:

./asm-generic/errno-base.h:#define EAGAIN 11 /* Try again */

function errno()
{
    local arg=$1

    if [[ "x$arg" == "x-h" ]]; then
        cat <<EOF
        Usage: errno <num>
        Prints text that describes errno error number
        EOF
    else
        pushd /usr/include
        find . -name "errno*.h" | xargs grep   "[[:space:]]${arg}[[:space:]]"
        popd
    fi
}

For a long time I have used the alternative:

('netscape' in window) && / rv:/.test(navigator.userAgent)

because I don't trust user agent strings. Some bugs are not detectable using feature detection, so detecting the browser is required for some workarounds.

Also if you are working around a bug in Gecko, then the bug is probably also in derivatives of Firefox, and this code should work with derivatives too (Do Waterfox and Pale Moon have 'Firefox' in the user agent string?).

Here's another dodge that I came up with for my base repository class where I needed to order by an arbitrary number of columns:

public function findAll(array $where = [], array $with = [], array $orderBy = [], int $limit = 10)
{
    $result = $this->model->with($with);
    $dataSet = $result->where($where)
        // Conditionally use $orderBy if not empty
        ->when(!empty($orderBy), function ($query) use ($orderBy) {
            // Break $orderBy into pairs
            $pairs = array_chunk($orderBy, 2);
            // Iterate over the pairs
            foreach ($pairs as $pair) {
                // Use the 'splat' to turn the pair into two arguments
                $query->orderBy(...$pair);
            }
        })
        ->paginate($limit)
        ->appends(Input::except('page'));

    return $dataSet;
}

Now, you can make your call like this:

$allUsers = $userRepository->findAll([], [], ['name', 'DESC', 'email', 'ASC'], 100);

The JTextField offers a getText() and a setText() method - those are for getting and setting the content of the text field.

Edit -> Project Settings -> Editor

Set Version Control to meta files. Set Asset Serialization to force text.

I think this is what you want.

It seems that MacPorts could be installed in El Capitan right now: https://www.macports.org/install.php Then you probably can install gdb by link you mentioned.

overflow-x: hidden;
would hide any thing on the x-axis that goes outside of the element, so there would be no need for the horizontal scrollbar and it get removed.

overflow-y: hidden;
would hide any thing on the y-axis that goes outside of the element, so there would be no need for the vertical scrollbar and it get removed.

overflow: hidden;
would remove both scrollbars

The default value can be followed with a : after the property key, e.g.

<property name="port" value="${my.server.port:8080}" />

Or in java code:

@Value("${my.server.port:8080}")
private String myServerPort;

There is 2 ways to do it in angularjs..

1) By directly redirecting to your service call..

<a href="some/path/to/the/file">clickme</a>

2) By submitting hidden form.

$scope.saveAsPDF = function() {
    var form = document.createElement("form");
    form.setAttribute("action", "some/path/to/the/file");
    form.setAttribute("method", "get");
    form.setAttribute("target", "_blank");

    var hiddenEle1 = document.createElement("input");
    hiddenEle1.setAttribute("type", "hidden");
    hiddenEle1.setAttribute("name", "some");
    hiddenEle1.setAttribute("value", value);

    form.append(hiddenEle1 );

    form.submit();

}

use the hidden element when you have to post some element

<button ng-click="saveAsPDF()">Save As PDF</button>

Simple way to compare time is :

$time = date('H:i:s',strtotime("11 PM"));
if($time < date('H:i:s')){
     // your code
}

You should inject a startup script that will close the page after the postback has finished.

ClientScript.RegisterStartupScript(typeof(Page), "closePage", "<script type='text/JavaScript'>window.close();</script>"); 

As of Xcode 8.2.1, iOS 10, and swift 3,

You can determine the end of tableView.reloadData() easily by using a CATransaction block:

CATransaction.begin()
CATransaction.setCompletionBlock({
    print("reload completed")
    //Your completion code here
})
print("reloading")
tableView.reloadData()
CATransaction.commit()

The above also works for determining the end of UICollectionView's reloadData() and UIPickerView's reloadAllComponents().

Honestly, I like the other answers. Easy and no need to get into JS. But I noticed that you were asking about jQuery. So for the sake of completeness, in jQuery if you return false with the .click() handler, it will negate the default action of the widget.

See here for an example (and more goodies, too). Here's the documentation, too.

in a nutshell, with your sample code, do this:

<script type="text/javascript">
    $('button[type!=submit]').click(function(){
        // code to cancel changes
        return false;
    });
</script>

<a href="index.html"><button>Cancel changes</button></a>
<button type="submit">Submit</button>

As an added benefit, with this, you can get rid of the anchor tag and just use the button.

Code :

 private void button1_Click(object sender, EventArgs e)
     {

        textBox1.Enabled=false;

            OpenFileDialog ofd = new OpenFileDialog();
            ofd.Filter = "Excell File |*.xlsx;*,xlsx";
            if (ofd.ShowDialog() == DialogResult.OK)
            {
                string extn = Path.GetExtension(ofd.FileName);
                if (extn.Equals(".xls") || extn.Equals(".xlsx"))
                {
                    filename = ofd.FileName;

                    if (filename != "")
                    {
                        try
                        {
                            string excelfilename = Path.GetFileName(filename);


                        }
                        catch (Exception ew)
                        {
                            MessageBox.Show("Errror:" + ew.ToString());
                        }
                    }
                }
            }

Why all these bit shifting operations and need for library functions? If you have the value the OP posted: 1011110 and you want to know if the bit in the 3rd position from the right is set, just do:

int temp = 0b1011110;
if( temp & 4 )   /* or (temp & 0b0100) if that's how you roll */
  DoSomething();

Or, something that may be more easily interpreted by future readers of the code with no #include needed:

int temp = 0b1011110;
_Bool bThirdBitIsSet = (temp & 4) ? 1 : 0;
if( bThirdBitIsSet )
  DoSomething();

Or if you like it to look a bit prettier:

#include <stdbool.h>
int temp = 0b1011110;
bool bThirdBitIsSet = (temp & 4) ? true : false;
if( bThirdBitIsSet )
  DoSomething();

If you just want to access the last item in the list you can do

if(integerList.Count>0)
{
   var item = integerList[integerList.Count - 1];
}

to get the total number of items in the list you can use the Count property

var itemCount = integerList.Count;

Per Byron's answer, you can't set networkaddress.cache.ttl or networkaddress.cache.negative.ttl as System Properties by using the -D flag or calling System.setProperty because these are not System properties - they are Security properties.

If you want to use a System property to trigger this behavior (so you can use the -D flag or call System.setProperty), you will want to set the following System property:

-Dsun.net.inetaddr.ttl=0

This system property will enable the desired effect.

But be aware: if you don't use the -D flag when starting the JVM process and elect to call this from code instead:

java.security.Security.setProperty("networkaddress.cache.ttl" , "0")

This code must execute before any other code in the JVM attempts to perform networking operations.

This is important because, for example, if you called Security.setProperty in a .war file and deployed that .war to Tomcat, this wouldn't work: Tomcat uses the Java networking stack to initialize itself much earlier than your .war's code is executed. Because of this 'race condition', it is usually more convenient to use the -D flag when starting the JVM process.

If you don't use -Dsun.net.inetaddr.ttl=0 or call Security.setProperty, you will need to edit $JRE_HOME/lib/security/java.security and set those security properties in that file, e.g.

networkaddress.cache.ttl = 0
networkaddress.cache.negative.ttl = 0

But pay attention to the security warnings in the comments surrounding those properties. Only do this if you are reasonably confident that you are not susceptible to DNS spoofing attacks.

On the selected answer I see that when initially the page is loaded the selection of first option is prior fixed and therefore gives the option of all the categories in selection 2. You can avoid that by adding the first option as the following in both the select tag:- <option value="none" selected disabled hidden>Select an Option</option>

<select name="select1" id="select1">
<option value="none" selected disabled hidden>Select an Option</option>
<option value="1">Fruit</option>
  <option value="2">Animal</option>
  <option value="3">Bird</option>
  <option value="4">Car</option>
</select>


<select name="select2" id="select2">
<option value="none" selected disabled hidden>Select an Option</option>
  <option value="1">Banana</option>
  <option value="1">Apple</option>
  <option value="1">Orange</option>
  <option value="2">Wolf</option>
  <option value="2">Fox</option>
  <option value="2">Bear</option>
  <option value="3">Eagle</option>
  <option value="3">Hawk</option>
  <option value="4">BWM<option>
</select>

To fix this in Dreamweaver CC 2018, I went to preferences, edit rule set - select JS, edit/apply changes, find "esnext" and changed the false setting to true. It worked for me after hours of research. Hope it helps others.

To delete the last element of the lists, you could use:

def deleteLast(self):
    if self.Ans:
        del self.Ans[-1]
    if self.masses:
        del self.masses[-1]

The simplest way to identify what needs to be set on the soap action when invoking WCF service through a java client would to load the wsdl, go to the operation name matching the service. From there pick up the action URI and set it in the soap action header. You are done.

eg: from wsdl

<wsdl:operation name="MyOperation">
  <wsdl:input wsaw:Action="http://tempuri.org/IMyService/MyOperation" message="tns:IMyService_MyOperation_InputMessage" />
  <wsdl:output wsaw:Action="http://tempuri.org/IMyService/MyServiceResponse" message="tns:IMyService_MyOperation_OutputMessage" />

Now in the java code we should set the soap action as the Action URI.

//The rest of the httpPost object properties have not been shown for brevity
string actionURI='http://tempuri.org/IMyService/MyOperation';
httpPost.setHeader( "SOAPAction", actionURI);

You have probably defined $name, $date, $text or $date2 to be a string, like:

$name = 'String';

Then if you treat it like an array it will give that fatal error:

$name[] = 'new value'; // fatal error

To solve your problem just add the following code at the beginning of the loop:

$name = array();
$date = array();
$text = array();
$date2 = array();

This will reset their value to array and then you'll able to use them as arrays.

I'd like to add to bosnic's answer that any valid currency character is legal for an identifier in Java. th€is is a legal identifier, as is €this, and € as well. However, I can't figure out how to edit his or her answer, so I am forced to post this trivial addition.

It sounds like you are trying to do something like this:

• Static HTML views
• Spring controllers serving AJAX

If that is the case, as previously mentioned, the most efficient way is to let the web server(not Spring) handle HTML requests as static resources. So you'll want the following:

1. Forward all .html, .css, .js, .png, etc requests to the webserver's resource handler
2. Map all other requests to spring controllers

Here is one way to accomplish that...

web.xml - Map servlet to root (/)

<servlet>
            <servlet-name>sprung</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            ...
<servlet>

        //controller mappings must be evaluated after the static resource requests
        handlerMapping.setOrder(1);
        handlerMapping.setInterceptors(this.getInterceptors());
        handlerMapping.setPathMatcher(this.getPathMatchConfigurer().getPathMatcher());
        handlerMapping.setRemoveSemicolonContent(false);
        handlerMapping.setUseSuffixPatternMatch(false);
        //set other options here
        return handlerMapping;
    }
}

Additional Considerations

• Hide .html extension - This is outside the scope of Spring if you are delegating the static resource requests. Look into a URL rewriting filter.
• Templating - You don't want to duplicate markup in every single HTML page for common elements. This likely can't be done on the server if serving HTML as a static resource. Look into a client-side *VC framework. I'm fan of YUI which has numerous templating mechanisms including Handlebars.

Your second solution is probably the most correct. You should use the HTTP spec and mimetypes the way they were intended and upload the file via multipart/form-data. As far as handling the relationships, I'd use this process (keeping in mind I know zero about your assumptions or system design):

1. POST to /users to create the user entity.
2. POST the image to /images, making sure to return a Location header to where the image can be retrieved per the HTTP spec.
3. PATCH to /users/carPhoto and assign it the ID of the photo given in the Location header of step 2.

Basic Usage

First, let's see what each function does:

regexObject.test( String )

Executes the search for a match between a regular expression and a specified string. Returns true or false.

string.match( RegExp )

Used to retrieve the matches when matching a string against a regular expression. Returns an array with the matches or null if there are none.

Since null evaluates to false,

if ( string.match(regex) ) {
  // There was a match.
} else {
  // No match.
} 

Performance

Is there any difference regarding performance?

Yes. I found this short note in the MDN site:

If you need to know if a string matches a regular expression regexp, use regexp.test(string).

Is the difference significant?

The answer once more is YES! This jsPerf I put together shows the difference is ~30% - ~60% depending on the browser:

Conclusion

Use .test if you want a faster boolean check. Use .match to retrieve all matches when using the g global flag.

JAVA_OPTS is environment variable used by tomcat in its startup/shutdown script to configure params.

You can set it in linux by

export JAVA_OPTS="-Djava.awt.headless=true" 

It's a good practice if you need them. It's also a good practice is they make sense, so future coders can understand what you're doing.

But generally, no it's not a good practice to attach 10 class names to an object because most likely whatever you're using them for, you could accomplish the same thing with far fewer classes. Probably just 1 or 2.

To qualify that statement, javascript plugins and scripts may append far more classnames to do whatever it is they're going to do. Modernizr for example appends anywhere from 5 - 25 classes to your body tag, and there's a very good reason for it. jQuery UI appends lots of classnames when you use one of the widgets in that library.

I encounter a problem in quasar which is a mobile framework based vue, the tidle syntax ~assets/cover.jpg works in normal component, but not in my dynamic defined component, that is defined by

let c=Vue.component('compName',{...})

finally this work:

    computed: {
      coverUri() {
        return require('../assets/cover.jpg');
      }
    }

<q-img class="coverImg" :src="coverUri" :height="uiBook.coverHeight" spinner-color="white"/>

according to the explain at https://quasar.dev/quasar-cli/handling-assets

In *.vue components, all your templates and CSS are parsed by vue-html-loader and css-loader to look for asset URLs. For example, in <img src="./logo.png"> and background: url(./logo.png), "./logo.png" is a relative asset path and will be resolved by Webpack as a module dependency.

If it's giving you errors with gtk, try qt.

sudo apt-get install libqt4-dev
cmake -D WITH_QT=ON ..
make
sudo make install

If this doesn't work, there's an easy way out.

sudo apt-get install libopencv-*

This will download all the required dependencies(although it seems that you have all the required libraries installed, but still you could try it once). This will probably install OpenCV 2.3.1 (Ubuntu 12.04). But since you have OpenCV 2.4.3 in /usr/local/lib include this path in /etc/ld.so.conf and do ldconfig. So now whenever you use OpenCV, you'd use the latest version. This is not the best way to do it but if you're still having problems with qt or gtk, try this once. This should work.

Update - 18th Jun 2019

I got this error on my Ubuntu(18.04.1 LTS) system for openCV 3.4.2, as the method call to cv2.imshow was failing (e.g., at the line of cv2.namedWindow(name) with error: cv2.error: OpenCV(3.4.2). The function is not implemented.). I am using anaconda. Just the below 2 steps helped me resolve:

conda remove opencv
conda install -c conda-forge opencv=4.1.0

If you are using pip, you can try

pip install opencv-contrib-python

In my case the error was caused because I was typing

git push origin master

while I was on the develop branch try:

git push origin branchname

Hope this helps somebody

To set the directory selected path and the retrieve the new directory:

dlgBrowseForLogDirectory.SelectedPath = m_LogDirectory;
if (dlgBrowseForLogDirectory.ShowDialog() == DialogResult.OK)
{
     txtLogDirectory.Text = dlgBrowseForLogDirectory.SelectedPath;
}

You're missing ;s. The general syntax if you put it all in one line would be:

if thing ; then ... ; else ... ; fi

The thing can be pretty much anything that returns an exit code. The then branch is taken if that thing returns 0, the else branch otherwise.

[ isn't syntax, it's the test program (check out ls /bin/[, it actually exists, man test for the docs – although can also have a built-in version with different/additional features.) which is used to test various common conditions on files and variables. (Note that [[ on the other hand is syntax and is handled by your shell, if it supports it).

For your case, you don't want to use test directly, you want to test something on the remote host. So try something like:

if ssh user@host test -e "$file" ; then ... ; else ... ; fi

I use WinMerge. It is free and works pretty well (works for files and directories).

I like using the ggplot2 for this sort of thing:

df$Date <- as.Date( df$Date, '%m/%d/%Y')
require(ggplot2)
ggplot( data = df, aes( Date, Visits )) + geom_line() 

First step: go to /etc/phpmyadmin/config.inc.php then uncomment lines where you find AllowNoPassword . Second step: login to your mysql default account

mysql -u root -p
use mysql;
update user set plugin="" where user='root';
flush privilege;

and that's all!

do you use jquery? if then:

$('#xx').val();

or use original javascript(DOM)

document.getElementById('xx').value

or

xxxform.xx.value;

If you frequently use a large number of exceptions, you can pre-define a tuple, so you don't have to re-type them many times.

#This example code is a technique I use in a library that connects with websites to gather data

ConnectErrs  = (URLError, SSLError, SocketTimeoutError, BadStatusLine, ConnectionResetError)

def connect(url, data):
    #do connection and return some data
    return(received_data)

def some_function(var_a, var_b, ...):
    try: o = connect(url, data)
    except ConnectErrs as e:
        #do the recovery stuff
    blah #do normal stuff you would do if no exception occurred

NOTES:

1. If you, also, need to catch other exceptions than those in the pre-defined tuple, you will need to define another except block.

2. If you just cannot tolerate a global variable, define it in main() and pass it around where needed...

Your code works as is for me. I'm verifying this by using netcat on Linux.

Using netcat, I can do nc -ul 127.0.0.1 5005 which will listen for packets at:

• IP: 127.0.0.1
• Port: 5005
• Protocol: UDP

That being said, here's the output that I see when I run your script, while having netcat running.

[9:34am][wlynch@watermelon ~] nc -ul 127.0.0.1 5005
Hello, World!

Use HttpServerUtility.UrlEncode

You can use ClassLoader.getResource method to get the correct resource.

URL res = getClass().getClassLoader().getResource("abc.txt");
File file = Paths.get(res.toURI()).toFile();
String absolutePath = file.getAbsolutePath();

OR

Although this may not work all the time, a simpler solution -

You can create a File object and use getAbsolutePath method:

File file = new File("resources/abc.txt");
String absolutePath = file.getAbsolutePath();

1. You can also achieve this using the backreference technique

   sed -i.bak 's/\(.*\)/\1:80/' foo.txt
   

2. You can also use with awk like this

   awk '{print $0":80"}' foo.txt > tmp && mv tmp foo.txt
   

@AnandaMahto has addressed why you're getting these results and provided the clearest way to get what you want. But another option would be to use identical instead of ==.

test$ID <- ifelse(is.na(test$time) | sapply(as.character(test$type), identical, "A"), NA, "1")

Or use isTRUE:

test$ID <- ifelse(is.na(test$time) | Vectorize(isTRUE)(test$type == "A"), NA, "1")

This site seems to keep a complete list that's still maintained

iPhone, iPod Touch, and iPad from iOS 2.0 - 5.1.1 (to date).

You do need to assemble the full user-agent string out of the information listed in the page's columns.

In case you need to set Gravity for a View use the following

Button b=new Button(Context);
b.setGravity(Gravity.CENTER);

For setting layout_gravity for the Button use gravity field for the layoutparams as

LayoutParams lp=new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
lp.gravity=Gravity.CENTER;

try this hope this clears thanks

I had the very same problem, and unfortunately it could not be solved by adding getter methods, or adding jackson dependencies.

I then looked at Official Spring Guide, and followed their example as given here - https://spring.io/guides/gs/actuator-service/ - where the example also shows the conversion of returned object to JSON format.

I then again made my own project, with the difference that this time I also added the dependencies and build plugins that's present in the pom.xml file of the Official Spring Guide example I mentioned above.

The modified dependencies and build part of XML file looks like this!

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

You can see the same in the mentioned link above.

And magically, atleast for me, it works. So, if you have already exhausted your other options, you might want to try this out, as was the case with me.

Just a side note, it didn't work for me when I added the dependencies in my previous project and did Maven install and update project stuff. So, I had to again make my project from scratch. I didn't bother much about it as mine is an example project, but you might want to look for that too!

hr {
    border: 1px dotted #ff0000;
    border-style: none none dotted;

Lifecycle hooks, like OnInit() work with Directives and Components. They do not work with other types, like a service in your case. From docs:

A Component has a lifecycle managed by Angular itself. Angular creates it, renders it, creates and renders its children, checks it when its data-bound properties change and destroy it before removing it from the DOM.

Directive and component instances have a lifecycle as Angular creates, updates, and destroys them.

As I understand the difference between a Static class and non-Static Singleton class, the static is simply a non-instantiated "type" in C#, where the Singleton is a true "object". In other words, all the static members in a static class are assigned to the type but in the Singleton are housed under the object. But keep in mind, a static class still behaves like a reference type as its not a value type like a Struct.

That means when you create a Singleton, because the class itself isnt static but its member is, the advantage is the static member inside the Singleton that refers to itself is connected to an actual "object" rather than a hollow "type" of itself. That sort of clarifies now the difference between a Static and a Non-Static Singleton beyond its other features and memory usage, which is confusing for me.

Both use static members which are single copies of a member, but the Singleton wraps the referenced member around a true instantiated "object" who's address exists in addition to its static member. That object itself has properties wherein in can be passed around and referenced, adding value. The Static class is just a type so it doesn't exist except to point to its static members. That concept sort of cemented the purpose of the Singleton vs Static Class beyond the inheritance and other issues.

A simpler way would be to create a link called cudart64_101.dll to point to cudart64_102.dll. This is not very orthodox but since TensorFlow is looking for cudart64_101.dll exported symbols and the nvidia folks are not amateurs, they would most likely not remove symbols from 101 to 102. It works, based on this assumption (mileage may vary).

This is an excerpt from Structure and Interpretation of Computer Programs about tail recursion.

In contrasting iteration and recursion, we must be careful not to confuse the notion of a recursive process with the notion of a recursive procedure. When we describe a procedure as recursive, we are referring to the syntactic fact that the procedure definition refers (either directly or indirectly) to the procedure itself. But when we describe a process as following a pattern that is, say, linearly recursive, we are speaking about how the process evolves, not about the syntax of how a procedure is written. It may seem disturbing that we refer to a recursive procedure such as fact-iter as generating an iterative process. However, the process really is iterative: Its state is captured completely by its three state variables, and an interpreter need keep track of only three variables in order to execute the process.

One reason that the distinction between process and procedure may be confusing is that most implementations of common languages (including Ada, Pascal, and C) are designed in such a way that the interpretation of any recursive procedure consumes an amount of memory that grows with the number of procedure calls, even when the process described is, in principle, iterative. As a consequence, these languages can describe iterative processes only by resorting to special-purpose “looping constructs” such as do, repeat, until, for, and while. The implementation of Scheme does not share this defect. It will execute an iterative process in constant space, even if the iterative process is described by a recursive procedure. An implementation with this property is called tail-recursive. With a tail-recursive implementation, iteration can be expressed using the ordinary procedure call mechanism, so that special iteration constructs are useful only as syntactic sugar.

I was already installed Android Studio and it's just need to add gradle PATH to ~/.bash_profile on my MacOSX Mojave. Also if gradle is upgraded then path might need to update again.

Example .bash_profile :

export ANDROID_SDK_ROOT="~/Library/Android/sdk"
export PATH=$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
export JAVA_HOME=$(/usr/libexec/java_home)
export GRADLE_PATH="~/.gradle/wrapper/dists/gradle-4.10.1-all/455itskqi2qtf0v2sja68alqd/gradle-4.10.1/bin"
export ANDROID_STUDIO="/Applications/Android Studio.app/Contents/MacOS"
export PATH="$PATH:$GRADLE_PATH:$ANDROID_STUDIO"

When edited your .bash_profile then run a command below to read it again.

source ~/.bash_profile

I had the same problem, however using Codeblocks. Because of this problem i quited programming because everytime i just wanted to throw my computer out of the window.

I want to thank user963228 whos answer is really a solution to that. You have to put Application Experience on Manual startup(you can do it by searching services in windows 7 start menu, and then find Application Experience and click properties).

This problem happens when people want to tweak theyr windows 7 machine, and they decide to disable some pointless services, so they google some tweaking guide and most of those guides say that Application Experience is safe to disable.

I think this problem should be linked to windows 7 problem not VS problem and it should be more visible - it took me long time to find this solution.

Thanks again!

I have used Newtonsoft JSON.NET (Documentation) It allows you to create a class / object, populate the fields, and serialize as JSON.

public class ReturnData 
{
    public int totalCount { get; set; }
    public List<ExceptionReport> reports { get; set; }  
}

public class ExceptionReport
{
    public int reportId { get; set; }
    public string message { get; set; }  
}


string json = JsonConvert.SerializeObject(myReturnData);

If your package name is more than two dot separated, say com.hello.world and moreover, you did not put anything in com/ and com/hello/. All of your classes are putting into com/hello/world/, you might DO the following steps to refactoring your package name(s) in Android Studio or IntelliJ:

• [FIRST] Add something under your directories(com/, com/hello/). You can achieve this by first add two files to package com.hello.world, say

   com.hello.world.PackageInfo1.java
   com.hello.world.PackageInfo2.java

then refactor them by moving them to com and com.hello respectively. You will see com and com.hello sitting there at the Project(Alt+1 or Command+1 for shortcut) and rename directories refactoring is waiting there as you expected.

• Refactor to rename one or more of these directories to reach your aim. The only thing you should notice here is you must choose the directories rather than Packages when a dialog ask you.

• If you've got lots of classes in your project, it will take you a while to wait for its auto-scan-and-rename.

• Besides, you need to rename the package name inside the AndroidManifest.xml manually, I guess, such that other names in this file can benefit the prefix.

• [ALSO], it might need you to replace all com.hello.world.R to the new XXX.XXX.XXX.R(Command+Shift+R for short)

• Rebuild and run your project to see whether it work. And use "Find in Path" to find other non-touch names you'd like to rename.

• Enjoy it.

axios.get accepts a request config as the second parameter (not query string params).

You can use the params config option to set query string params as follows:

axios.get('/api', {
  params: {
    foo: 'bar'
  }
});

For me just using cntlm -H wasn't generating the right hash, but it does with the command below providing the user name.

If you need to generate a new password hash for cntlm, because you have change it or you've been forced to update it, you can just type the below command and update your cntlm.conf configuration file with the output:

$ cntlm -u test -H
Password: 
PassLM          D2AABAF8828482D5552C4BCA4AEBFB11
PassNT          83AC305A1582F064C469755F04AE5C0A
PassNTLMv2      4B80D9370D353EE006D714E39715A5CB    # Only for user 'test', domain ''

If you wanna have everything into one only piece of code, then you can mix tim's answer with the example's approach found on the API for JTextField, and you'll get something like this:

public class JTextFieldLimit extends JTextField {
    private int limit;

    public JTextFieldLimit(int limit) {
        super();
        this.limit = limit;
    }

    @Override
    protected Document createDefaultModel() {
        return new LimitDocument();
    }

    private class LimitDocument extends PlainDocument {

        @Override
        public void insertString( int offset, String  str, AttributeSet attr ) throws BadLocationException {
            if (str == null) return;

            if ((getLength() + str.length()) <= limit) {
                super.insertString(offset, str, attr);
            }
        }       

    }

}

Then there is no need to add a Document to the JTextFieldLimit due to JTextFieldLimit already have the functionality inside.

Here are some of your options:

char a1[][14] = { "blah", "hmm" };
char* a2[] = { "blah", "hmm" };
char (*a3[])[] = { &"blah", &"hmm" };  // only since you brought up the syntax -

printf(a1[0]); // prints blah
printf(a2[0]); // prints blah
printf(*a3[0]); // prints blah

The advantage of a2 is that you can then do the following with string literals

a2[0] = "hmm";
a2[1] = "blah";

And for a3 you may do the following:

a3[0] = &"hmm";
a3[1] = &"blah";

For a1 you will have to use strcpy() (better yet strncpy()) even when assigning string literals. The reason is that a2, and a3 are arrays of pointers and you can make their elements (i.e. pointers) point to any storage, whereas a1 is an array of 'array of chars' and so each element is an array that "owns" its own storage (which means it gets destroyed when it goes out of scope) - you can only copy stuff into its storage.

This also brings us to the disadvantage of using a2 and a3 - since they point to static storage (where string literals are stored) the contents of which cannot be reliably changed (viz. undefined behavior), if you want to assign non-string literals to the elements of a2 or a3 - you will first have to dynamically allocate enough memory and then have their elements point to this memory, and then copy the characters into it - and then you have to be sure to deallocate the memory when done.

Bah - I miss C++ already ;)

p.s. Let me know if you need examples.

A simpler and imho better solution is:

Console.Write("\r" + new string(' ', Console.WindowWidth) + "\r");

It uses the carriage return to go to the beginning of the line, then prints as many spaces as the console is width and returns to the beginning of the line again, so you can print your own test afterwards.

To add to Kevin's answer, I find that in practice nearly all of your non-trivial Spring MVC applications will require an application context (as opposed to only the spring MVC dispatcher servlet context). It is in the application context that you should configure all non-web related concerns such as:

• Security
• Persistence
• Scheduled Tasks
• Others?

To make this a bit more concrete, here's an example of the Spring configuration I've used when setting up a modern (Spring version 4.1.2) Spring MVC application. Personally, I prefer to still use a WEB-INF/web.xml file but that's really the only xml configuration in sight.

WEB-INF/web.xml

As you can see, the web configuration is only a small part of the overall spring web application configuration. Most web applications I've worked with have many concerns that lie outside of the dispatcher servlet configuration that require a full-blown application context bootstrapped via the org.springframework.web.context.ContextLoaderListener in the web.xml.

what u can also do i place an extra "dummy" div before your last div.

Make it 1 px heigh and the width as much needed to cover the container div/body

This will make the last div appear under it, starting from the left.

If your lists are a and b, you can do:

map(int.__sub__, a, b)

But you probably shouldn't. No one will know what it means.

There's always a goto statement, but I would recommend nesting an if with an inverse of the breaking condition.

It's a general comparison operator. It returns either a -1, 0, or +1 depending on whether its receiver is less than, equal to, or greater than its argument.

It boggles my mind why so may people write the increment expression in for-loop as i++.

In a for-loop, when the 3rd component is a simple increment statement, as in

for (i=0; i<x; i++)  

or

for (i=0; i<x; ++i)   

there is no difference in the resulting executions.

Ideally you would put that in a directive, but you can also just put it in the controller. http://jsfiddle.net/tnq86/15/

  angular.module('App', [])
    .controller('AppCtrl', function ($scope) {

      $scope.model = 0;

      $scope.initSlider = function () {
          $(function () {
            // wait till load event fires so all resources are available
              $scope.$slider = $('#slider').slider({
                  slide: $scope.onSlide
              });
          });

          $scope.onSlide = function (e, ui) {
             $scope.model = ui.value;
             $scope.$digest();
          };
      };

      $scope.initSlider();
  });

The directive approach:

HTML

<div slider></div>

JS

  angular.module('App', [])
    .directive('slider', function (DataModel) {
      return {
         restrict: 'A',
         scope: true,
         controller: function ($scope, $element, $attrs) {
            $scope.onSlide = function (e, ui) {
              $scope.model = ui.value;
              // or set it on the model
              // DataModel.model = ui.value;
              // add to angular digest cycle
              $scope.$digest();
            };
         },
         link: function (scope, el, attrs) {

            var options = {
              slide: scope.onSlide  
            };

            // set up slider on load
            angular.element(document).ready(function () {
              scope.$slider = $(el).slider(options);
            });
         }
      }
  });

I would also recommend checking out Angular Bootstrap's source code: https://github.com/angular-ui/bootstrap/blob/master/src/tooltip/tooltip.js

You can also use a factory to create the directive. This gives you ultimate flexibility to integrate services around it and whatever dependencies you need.

Any of the following will remove column foo from the data.table df3:

# Method 1 (and preferred as it takes 0.00s even on a 20GB data.table)
df3[,foo:=NULL]

df3[, c("foo","bar"):=NULL]  # remove two columns

myVar = "foo"
df3[, (myVar):=NULL]   # lookup myVar contents

# Method 2a -- A safe idiom for excluding (possibly multiple)
# columns matching a regex
df3[, grep("^foo$", colnames(df3)):=NULL]

# Method 2b -- An alternative to 2a, also "safe" in the sense described below
df3[, which(grepl("^foo$", colnames(df3))):=NULL]

data.table also supports the following syntax:

## Method 3 (could then assign to df3, 
df3[, !"foo"]  

though if you were actually wanting to remove column "foo" from df3 (as opposed to just printing a view of df3 minus column "foo") you'd really want to use Method 1 instead.

(Do note that if you use a method relying on grep() or grepl(), you need to set pattern="^foo$" rather than "foo", if you don't want columns with names like "fool" and "buffoon" (i.e. those containing foo as a substring) to also be matched and removed.)

Less safe options, fine for interactive use:

The next two idioms will also work -- if df3 contains a column matching "foo" -- but will fail in a probably-unexpected way if it does not. If, for instance, you use any of them to search for the non-existent column "bar", you'll end up with a zero-row data.table.

As a consequence, they are really best suited for interactive use where one might, e.g., want to display a data.table minus any columns with names containing the substring "foo". For programming purposes (or if you are wanting to actually remove the column(s) from df3 rather than from a copy of it), Methods 1, 2a, and 2b are really the best options.

# Method 4:
df3[, .SD, .SDcols = !patterns("^foo$")]

Lastly there are approaches using with=FALSE, though data.table is gradually moving away from using this argument so it's now discouraged where you can avoid it; showing here so you know the option exists in case you really do need it:

# Method 5a (like Method 3)
df3[, !"foo", with=FALSE] 
# Method 5b (like Method 4)
df3[, !grep("^foo$", names(df3)), with=FALSE]
# Method 5b (another like Method 4)
df3[, !grepl("^foo$", names(df3)), with=FALSE]

The simplest and easiest way is to execute your particular script with -NoExit param.

1.Open run box by pressing:

Win + R

2.Then type into input prompt:

PowerShell -NoExit "C:\folder\script.ps1"

and execute.

This question is for ruby 1.8 but it still comes on top when googling.

in ruby >= 1.9 you can use

File.write("public/temp.json",tempHash.to_json)

other than what mentioned in other answers, in ruby 1.8 you can also use one liner form

File.open("public/temp.json","w"){ |f| f.write tempHash.to_json }

Select the project -> Right-Click -> clean and build and then run the project again simply solve the problem for me.

As, multiple process could bind the same port for example port 8086, In that case I have to kill all the processes involved with the port with PID. That might be cumbersome.

In SQL Server 2012 you can use SUM() with the OVER() clause.

select id,
       somedate,
       somevalue,
       sum(somevalue) over(order by somedate rows unbounded preceding) as runningtotal
from TestTable

SQL Fiddle

Try:

alert(arguments.callee.toString());

//Set the values
intent.putParcelableArrayListExtra("key",collection);

//Retrieve the values
ArrayList<OnlineMember> onlineMembers = data.getParcelableArrayListExtra("key");

Means Not a Number. It is a common representation for an impossible numeric value in many programming languages.

I haven't checked (although it wouldn't be hard to), but I think that Stack Exchange sites use the jquery.timeago plugin to create these time strings.

It's quite easy to use the plugin, and it's clean and updates automatically.

Here's a quick sample (from the plugin's home page):

First, load jQuery and the plugin:

<script src="jquery.min.js" type="text/javascript"></script> <script src="jquery.timeago.js" type="text/javascript"></script>

Now, let's attach it to your timestamps on DOM ready:

jQuery(document).ready(function() {
jQuery("abbr.timeago").timeago(); });

This will turn all abbr elements with a class of timeago and an ISO 8601 timestamp in the title: <abbr class="timeago" title="2008-07-17T09:24:17Z">July 17, 2008</abbr> into something like this: <abbr class="timeago" title="July 17, 2008">about a year ago</abbr> which yields: about a year ago. As time passes, the timestamps will automatically update.

To extend onto above answers, You can actually add more than one package in your EnableJPARepositories tag, so that you won't run into "Object not mapped" error after only specifying the repository package.

@SpringBootApplication
@EnableJpaRepositories(basePackages = {"com.test.model", "com.test.repository"})
public class SpringBootApplication{

}

On the last entry; this is another trick:

SELECT AUTO_INCREMENT FROM information_schema.tables WHERE table_schema = ... and table_name = ...

What you are seeing is a parameterized query. They are frequently used when executing dynamic SQL from a program.

For example, instead of writing this (note: pseudocode):

ODBCCommand cmd = new ODBCCommand("SELECT thingA FROM tableA WHERE thingB = 7")
result = cmd.Execute()

You write this:

ODBCCommand cmd = new ODBCCommand("SELECT thingA FROM tableA WHERE thingB = ?")
cmd.Parameters.Add(7)
result = cmd.Execute()

This has many advantages, as is probably obvious. One of the most important: the library functions which parse your parameters are clever, and ensure that strings are escaped properly. For example, if you write this:

string s = getStudentName()
cmd.CommandText = "SELECT * FROM students WHERE (name = '" + s + "')"
cmd.Execute()

What happens when the user enters this?

Robert'); DROP TABLE students; --

(Answer is here)

Write this instead:

s = getStudentName()
cmd.CommandText = "SELECT * FROM students WHERE name = ?"
cmd.Parameters.Add(s)
cmd.Execute()

Then the library will sanitize the input, producing this:

"SELECT * FROM students where name = 'Robert''); DROP TABLE students; --'"

Not all DBMS's use ?. MS SQL uses named parameters, which I consider a huge improvement:

cmd.Text = "SELECT thingA FROM tableA WHERE thingB = @varname"
cmd.Parameters.AddWithValue("@varname", 7)
result = cmd.Execute()

Long story short, node draws from V8, which is internally single-threaded. There are ways to work around the constraints for CPU-intensive tasks.

At one point (0.7) the authors tried to introduce isolates as a way of implementing multiple threads of computation, but were ultimately removed: https://groups.google.com/forum/#!msg/nodejs/zLzuo292hX0/F7gqfUiKi2sJ

I'll explain it in a way that made sense to me:

• Compute Engine: If you are do-it-yourself person or have an IT team and you just want to rent a computer on cloud that has specific OS (for example linux), you go for the Compute Engine. You have to do everything by yourself.

• App Engine: If you are (for example) a python programmer and you want to rent a pre-configured computer on cloud that has Linux with a running web-server and the latest python 3 with necessary modules and some plug-ins to integrate with other external services, you go for the App Engine.

• Serverless Container (Cloud Run): If you would like to deploy the exact image of your local setup environment (for example: python 3.7+flask+sklearn) but you do not want to deal with server, scaling, etc. You create a container on your local machine (through docker) and then deploy it to Google Run.

• Serverless Microservice (Cloud Functions): If you want to write bunch of APIs (functions) that do specific job, you go for google Cloud Functions. You just focus on those specific functions, the rest of the job (server, maintenance, scaling, etc.) is done for you in order to expose your functions as microservices.

As you go deeper, you lose some flexibility but you are not worried about unnecessary technical aspects. You also pay a little more but you save time and cost (IT part): someone else (google) is doing it for you.

If you want to not care about load balancing, scaling, etc., it is crucial to split your app to bunch of "stateless" web services that writes anything persistent in a separate storage (database or blob storage). Then you will found how awesome is Cloud Run and Cloud Functions.

Personally, I found Google Cloud Run an awesome solution, absolute freedom in development (as long as stateless), expose it as a web service, docker your solution, deploy it with Cloud Run. Let google be your IT and DevOps, you do not need to care about scaling and maintenance.

I have tried all other options and each one is good for different purpose but Google Run is just awesome. To me, it is the real serverless without losing flexibility in development.

The "-r" option is invalid on my systems. I had to use a different syntax for the "From" field.

-a "From: Foo Bar <[email protected]>"

Installed in ubuntu 18.04

My workaround was,

$ sudo apt update

Install OpenJDK 8:

$ sudo apt install openjdk-8-jdk

Verify the Java installation by running the following command which will print the Java version:

$ java -version

The output should look like this:

Output:

openjdk version "1.8.0_191"
OpenJDK Runtime Environment (build 1.8.0_191-8u191-b12-2ubuntu0.18.04.1-b12)

Your countLines(String filename) method throws IOException.

You can't use it in a member declaration. You'll need to perform the operation in a main(String[] args) method.

Your main(String[] args) method will get the IOException thrown to it by countLines and it will need to handle or declare it.

Try this to just throw the IOException from main

public class MyClass {
  private int lineCount;
  public static void main(String[] args) throws IOException {
    lineCount = LineCounter.countLines(sFileName);
  }
}

or this to handle it and wrap it in an unchecked IllegalArgumentException:

public class MyClass {
  private int lineCount;
  private String sFileName  = "myfile";
  public static void main(String[] args) throws IOException {
    try {
      lineCount = LineCounter.countLines(sFileName);
     } catch (IOException e) {
       throw new IllegalArgumentException("Unable to load " + sFileName, e);
     }
  }
}

textarea {
width: 700px;  
height: 100px;
resize: none; }

assign your required width and height for the textarea and then use. resize: none ; css property which will disable the textarea's stretchable property.

It is very important that you tell the browser what type of data you are sending it. The difference should be obvious. Try viewing the output of the following PHP file in your browser;

<?php
header('Content-Type:text/html');
?>
<p>Hello</p>

You will see:

hello

(note that you will get the same results if you miss off the header line in this case - text/html is php's default)

Change it to text/plain

<?php
header('Content-Type:text/plain');
?>
<p>Hello</p>

You will see:

<p>Hello</p>

Why does this matter? If you have something like the following in a php script that, for example, is used by an ajax request:

<?php
header('Content-Type:text/html');
print "Your name is " . $_GET['name']

Someone can put a link to a URL like http://example.com/test.php?name=%3Cscript%20src=%22http://example.com/eviljs%22%3E%3C/script%3E on their site, and if a user clicks it, they have exposed all their information on your site to whoever put up the link. If you serve the file as text/plain, you are safe.

Note that this is a silly example, it's more likely that the bad script tag would be added by the attacker to a field in the database or by using a form submission.

I had the same issue and tried almost everything then found after I came to know I was trying it in the wrong block. I was trying it in steps block whereas it needs to be in the environment block.

        stage('Release') {
                    environment {
                            my_var = sh(script: "/bin/bash ${assign_version} || ls ", , returnStdout: true).trim()
                                }
                    steps {                                 
                            println my_var
                            }
                }

The gdi32 library is already installed on your computer, few programs will run without it. Your compiler will (if installed properly) normally come with an import library, which is what the linker uses to make a binding between your program and the file in the system. (In the unlikely case that your compiler does not come with import libraries for the system libs, you will need to download the Microsoft Windows Platform SDK.)

To link with gdi32:

This will reliably work with MinGW-gcc for all system libraries (it should work if you use any other compiler too, but I can't talk about things I've not tried). You can also write the library's full name, but writing libgdi32.a has no advantage over gdi32 other than being more type work.
If it does not work for some reason, you may have to provide a different name (for example the library is named gdi32.lib for MSVC).

For libraries in some odd locations or project subfolders, you will need to provide a proper pathname (click on the "..." button for a file select dialog).

wait also (optionally) takes the PID of the process to wait for, and with $! you get the PID of the last command launched in background. Modify the loop to store the PID of each spawned sub-process into an array, and then loop again waiting on each PID.

# run processes and store pids in array
for i in $n_procs; do
    ./procs[${i}] &
    pids[${i}]=$!
done

# wait for all pids
for pid in ${pids[*]}; do
    wait $pid
done

Old thread I know but I am sort of new to Java and discover one of it's strange things. I have used String.replaceAll() but get unpredictable results.

Something like this mess up the string:

sUrl = sUrl.replaceAll( "./", "//").replaceAll( "//", "/");

So I designed this function to get around the weird problem:

//String.replaceAll does not work OK, that's why this function is here
public String strReplace( String s1, String s2, String s ) 
{
    if((( s == null ) || (s.length() == 0 )) || (( s1 == null ) || (s1.length() == 0 )))
     { return s; }

   while( (s != null) && (s.indexOf( s1 ) >= 0) )
    { s = s.replace( s1, s2 ); }
  return s;
}

Which make you able to do:

sUrl=this.strReplace("./", "//", sUrl );
sUrl=this.strReplace( "//", "/", sUrl );

Here's the function I created to read the variable names. It's more general and can be used in different applications:

def get_variable_name(*variable):
    '''gets string of variable name
    inputs
        variable (str)
    returns
        string
    '''
    if len(variable) != 1:
        raise Exception('len of variables inputed must be 1')
    try:
        return [k for k, v in locals().items() if v is variable[0]][0]
    except:
        return [k for k, v in globals().items() if v is variable[0]][0]

To use it in the specified question:

>>> foo = False
>>> bar = True
>>> my_dict = {get_variable_name(foo):foo, 
               get_variable_name(bar):bar}
>>> my_dict
{'bar': True, 'foo': False}

G'day,

As a corollary to this question, communicate your interpretations of the log levels and make sure that all people on a project are aligned in their interpretation of the levels.

It's painful to see a vast variety of log messages where the severities and the selected log levels are inconsistent.

Provide examples if possible of the different logging levels. And be consistent in the info to be logged in a message.

HTH

As mentioned in comments, you are still able to access element by navigating between elements by using tab key. so I recommend this :

$("#mydiv")
  .css({"pointer-events" : "none" , "opacity" :  "0.4"})
  .attr("tabindex" , "-1");

The use operator is for giving aliases to names of classes, interfaces or other namespaces. Most use statements refer to a namespace or class that you'd like to shorten:

use My\Full\Namespace;

is equivalent to:

use My\Full\Namespace as Namespace;
// Namespace\Foo is now shorthand for My\Full\Namespace\Foo

If the use operator is used with a class or interface name, it has the following uses:

// after this, "new DifferentName();" would instantiate a My\Full\Classname
use My\Full\Classname as DifferentName;

// global class - making "new ArrayObject()" and "new \ArrayObject()" equivalent
use ArrayObject;

The use operator is not to be confused with autoloading. A class is autoloaded (negating the need for include) by registering an autoloader (e.g. with spl_autoload_register). You might want to read PSR-4 to see a suitable autoloader implementation.

There is also some simple solution without mapping node_module directory into another volume. It's about to move installing npm packages into final CMD command.

Disadvantage of this approach:

• run npm install each time you run container (switching from npm to yarn might also speed up this process a bit).

worker/Dockerfile

FROM node:0.12
WORKDIR /worker
COPY package.json /worker/
COPY . /worker/
CMD /bin/bash -c 'npm install; npm start'

docker-compose.yml

redis:
    image: redis
worker:
    build: ./worker
    ports:
        - "9730:9730"
    volumes:
        - worker/:/worker/
    links:
        - redis

For this, I prefer to keep a correct HTML semantic, and to use a CSS simple as possible.

Something like this would do the job :

label{
  display: block;
  float: left;
  width : 120px;    
}

One drawback however : you might have to pick the right label width for each form, and this is not easy if your labels can be dynamic (I18N labels for instance).

$.ajax({    
    type: 'POST',  
    url: 'test.php',  
    data:$("#Test-form").serialize(),  
    dataType:'json',
     beforeSend:function(xhr, settings){
     settings.data += '&moreinfo=MoreData';
     },
    success:function(data){
            //  json response  
    },
    error: function(data) { 
        // if error occured
    }
    });

HTTP transaction, basic access authentication, is not suitable for RBAC, because basic access authentication uses the encrypted username:password every time to identify, while what is needed in RBAC is the Role the user wants to use for a specific call. RBAC does not validate permissions on username, but on roles.

You could tric around to concatenate like this: usernameRole:password, but this is bad practice, and it is also inefficient because when a user has more roles, the authentication engine would need to test all roles in concatenation, and that every call again. This would destroy one of the biggest technical advantages of RBAC, namely a very quick authorization-test.

So that problem cannot be solved using basic access authentication.

To solve this problem, session-maintaining is necessary, and that seems, according to some answers, in contradiction with REST.

That is what I like about the answer that REST should not be treated as a religion. In complex business cases, in healthcare, for example, RBAC is absolutely common and necessary. And it would be a pity if they would not be allowed to use REST because all REST-tools designers would treat REST as a religion.

For me there are not many ways to maintain a session over HTTP. One can use cookies, with a sessionId, or a header with a sessionId.

If someone has another idea I will be glad to hear it.

This works for me

 var link_click = $('#google').get(0).attributes.onclick.nodeValue;
 console.log(link_click);

Recommended is to use JSON.parse

There is an alternative you can do :

 var myObject = eval('(' + myJSONtext + ')');

Json in javascript

Why is using the JavaScript eval function a bad idea?

If the same key and initialization vector are used for encoding and decoding, this issue does not come from data decoding but from data encoding.

After you called Write method on a CryptoStream object, you must ALWAYS call FlushFinalBlock method before Close method.

MSDN documentation on CryptoStream.FlushFinalBlock method says:
"Calling the Close method will call FlushFinalBlock ..."
https://msdn.microsoft.com/en-US/library/system.security.cryptography.cryptostream.flushfinalblock(v=vs.110).aspx
This is wrong. Calling Close method just closes the CryptoStream and the output Stream.
If you do not call FlushFinalBlock before Close after you wrote data to be encrypted, when decrypting data, a call to Read or CopyTo method on your CryptoStream object will raise a CryptographicException exception (message: "Padding is invalid and cannot be removed").

This is probably true for all encryption algorithms derived from SymmetricAlgorithm (Aes, DES, RC2, Rijndael, TripleDES), although I just verified that for AesManaged and a MemoryStream as output Stream.

So, if you receive this CryptographicException exception on decryption, read your output Stream Length property value after you wrote your data to be encrypted, then call FlushFinalBlock and read its value again. If it has changed, you know that calling FlushFinalBlock is NOT optional.

And you do not need to perform any padding programmatically, or choose another Padding property value. Padding is FlushFinalBlock method job.

.........

Additional remark for Kevin:

Yes, CryptoStream calls FlushFinalBlock before calling Close, but it is too late: when CryptoStream Close method is called, the output stream is also closed.

If your output stream is a MemoryStream, you cannot read its data after it is closed. So you need to call FlushFinalBlock on your CryptoStream before using the encrypted data written on the MemoryStream.

If your output stream is a FileStream, things are worse because writing is buffered. The consequence is last written bytes may not be written to the file if you close the output stream before calling Flush on FileStream. So before calling Close on CryptoStream you first need to call FlushFinalBlock on your CryptoStream then call Flush on your FileStream.

Of these two, the first one is a type mistake: '\0' is a character, not a pointer. The compiler still accepts it because it can convert it to a pointer.

The second one "works" only by coincidence. "\0" is a string literal of two characters. If those occur in multiple places in the source file, the compiler may, but need not, make them identical.

So the proper way to write the first one is

char* array[] = { "abc", "def", NULL };

and you test for array[index]==NULL. The proper way to test for the second one is array[index][0]=='\0'; you may also drop the '\0' in the string (i.e. spell it as "") since that will already include a null byte.

You have to resolve the conflict manually (copying the file over) and then commit the file (no matter if you copied it over or used the local version) like this

git commit -a -m "Fix merge conflict in test.foo"

Git normally autocommits after merging, but when it detects conflicts it cannot solve by itself, it applies all patches it figured out and leaves the rest for you to resolve and commit manually. The Git Merge Man Page, the Git-SVN Crash Course or this blog entry might shed some light on how it's supposed to work.

Edit: See the post below, you don't actually have to copy the files yourself, but can use

git checkout --ours -- path/to/file.txt
git checkout --theirs -- path/to/file.txt

to select the version of the file you want. Copying / editing the file will only be necessary if you want a mix of both versions.

Please mark mipadis answer as the correct one.

The opposite of this is to flatten a column into a csv eg

SELECT STRING_AGG ([value],',') FROM STRING_SPLIT('Akio,Hiraku,Kazuo', ',')

Implicit waits are used to provide a default waiting time between each consecutive test step/command across the entire test script. Thus, subsequent test step would only execute when the specified amount of time have elapsed after executing the previous test step/command.

Explicit waits are used to halt the execution till the time a particular condition is met or the maximum time has elapsed. Unlike Implicit waits, Explicit waits are applied for a particular instance only.

That format is perfectly appropriate for a standard string comparison e.g.

if ($date1 > $date2){
  //Action
}

To get today's date in that format, simply use: date("Y-m-d H:i:s").

So:

$today = date("Y-m-d H:i:s");
$date = "2010-01-21 00:00:00";

if ($date < $today) {}

That's the beauty of that format: it orders nicely. Of course, that may be less efficient, depending on your exact circumstances, but it might also be a whole lot more convenient and lead to more maintainable code - we'd need to know more to truly make that judgement call.

For the correct timezone, you can use, for example,

date_default_timezone_set('America/New_York');

add \ before special characters:

etc.

Several problems here:

• You probably don't use the correct iterator class. As others said, use import java.util.Iterator
• If you want to use Map.Entry entry = (Map.Entry) iter.next(); then you need to use hm.entrySet().iterator(), not hm.keySet().iterator(). Either you iterate on the keys, or on the entries.

This worked for me. 1. Click on Window-> Preferences -> Installed JRE. 2. Check if you reference is for JDK as shown in the image below.

3. Last step, click on Installed JREs -> Execution Environments -> select your JDE as shown in the image below

4. Maven -> Clean

I will tell you steps how you can insert data in ajax using PHP

AJAX Code

<script type="text/javascript">
function insertData() {
var student_name=$("#student_name").val();
var student_roll_no=$("#student_roll_no").val();
var student_class=$("#student_class").val();


// AJAX code to send data to php file.
    $.ajax({
        type: "POST",
        url: "insert-data.php",
        data: {student_name:student_name,student_roll_no:student_roll_no,student_class:s
         tudent_class},
        dataType: "JSON",
        success: function(data) {
         $("#message").html(data);
        $("p").addClass("alert alert-success");
        },
        error: function(err) {
        alert(err);
        }
    });

 }

</script>

PHP Code:

<?php

include('db.php');
$student_name=$_POST['student_name'];
$student_roll_no=$_POST['student_roll_no'];
$student_class=$_POST['student_class'];

$stmt = $DBcon->prepare("INSERT INTO 
student(student_name,student_roll_no,student_class) 
VALUES(:student_name, :student_roll_no,:student_class)");

 $stmt->bindparam(':student_name', $student_name);
 $stmt->bindparam(':student_roll_no', $student_roll_no);
 $stmt->bindparam(':student_class', $student_class);
 if($stmt->execute())
 {
  $res="Data Inserted Successfully:";
  echo json_encode($res);
  }
  else {
  $error="Not Inserted,Some Probelm occur.";
  echo json_encode($error);
  }



  ?>

Importing Jobs Manually: Alternate way

Upload the Jobs on to Git (Version Control) Basically upload config.xml of the Job.

If Linux Servers:

cd /var/lib/jenkins/jobs/<Job name> 
Download the config.xml from Git

Restart the Jenkins

You can write yourself a little console app and use System.Environment.Version to find out the version. Scott Hanselman gives a blog post about it.

Or look in the registry for the installed versions. HKLM\Software\Microsoft\NETFramework Setup\NDP

It's better to not use array_push and just use what you suggested. The functions just add overhead.

//We don't need to define the array, but in many cases it's the best solution.
$cart = array();

//Automatic new integer key higher than the highest 
//existing integer key in the array, starts at 0.
$cart[] = 13;
$cart[] = 'text';

//Numeric key
$cart[4] = $object;

//Text key (assoc)
$cart['key'] = 'test';

Here is how the default implementation (ASP.NET Framework or ASP.NET Core) works. It uses a Key Derivation Function with random salt to produce the hash. The salt is included as part of the output of the KDF. Thus, each time you "hash" the same password you will get different hashes. To verify the hash the output is split back to the salt and the rest, and the KDF is run again on the password with the specified salt. If the result matches to the rest of the initial output the hash is verified.

Hashing:

public static string HashPassword(string password)
{
    byte[] salt;
    byte[] buffer2;
    if (password == null)
    {
        throw new ArgumentNullException("password");
    }
    using (Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(password, 0x10, 0x3e8))
    {
        salt = bytes.Salt;
        buffer2 = bytes.GetBytes(0x20);
    }
    byte[] dst = new byte[0x31];
    Buffer.BlockCopy(salt, 0, dst, 1, 0x10);
    Buffer.BlockCopy(buffer2, 0, dst, 0x11, 0x20);
    return Convert.ToBase64String(dst);
}

Verifying:

public static bool VerifyHashedPassword(string hashedPassword, string password)
{
    byte[] buffer4;
    if (hashedPassword == null)
    {
        return false;
    }
    if (password == null)
    {
        throw new ArgumentNullException("password");
    }
    byte[] src = Convert.FromBase64String(hashedPassword);
    if ((src.Length != 0x31) || (src[0] != 0))
    {
        return false;
    }
    byte[] dst = new byte[0x10];
    Buffer.BlockCopy(src, 1, dst, 0, 0x10);
    byte[] buffer3 = new byte[0x20];
    Buffer.BlockCopy(src, 0x11, buffer3, 0, 0x20);
    using (Rfc2898DeriveBytes bytes = new Rfc2898DeriveBytes(password, dst, 0x3e8))
    {
        buffer4 = bytes.GetBytes(0x20);
    }
    return ByteArraysEqual(buffer3, buffer4);
}

I found information about .bashrc and .bash_profile here to sum it up:

.bash_profile is executed when you login. Stuff you put in there might be your PATH and other important environment variables.

.bashrc is used for non login shells. I'm not sure what that means. I know that RedHat executes it everytime you start another shell (su to this user or simply calling bash again) You might want to put aliases in there but again I am not sure what that means. I simply ignore it myself.

.profile is the equivalent of .bash_profile for the root. I think the name is changed to let other shells (csh, sh, tcsh) use it as well. (you don't need one as a user)

There is also .bash_logout wich executes at, yeah good guess...logout. You might want to stop deamons or even make a little housekeeping . You can also add "clear" there if you want to clear the screen when you log out.

Also there is a complete follow up on each of the configurations files here

These are probably even distro.-dependant, not all distros choose to have each configuraton with them and some have even more. But when they have the same name, they usualy include the same content.

Since you're using jQuery, you can just set the element's text property:

// before:
// <div class="someClass">text</div>
var someHtmlString = "<script>alert('hi!');</script>";

// set a DIV's text:
$("div.someClass").text(someHtmlString);
// after: 
// <div class="someClass">&lt;script&gt;alert('hi!');&lt;/script&gt;</div>

// get the text in a string:
var escaped = $("<div>").text(someHtmlString).html();
// value: 
// &lt;script&gt;alert('hi!');&lt;/script&gt;

iif has always been available in VB, even in VB6.

Dim foo as String = iif(bar = buz, cat, dog)

When uploading an image, its filename is not kept in the database. It is renamed as Image.jpg (to simply things out when using it).

Change this, and you've fixed your problem. I use timestamps, as with the solutions proposed above: Image-<timestamp>.jpg

Presumably, whatever problems you're avoiding by keeping the same filename for the image can be overcome, but you don't say what they are.

It is very easy to connect remote MySQL Server Using PHP, what you have to do is:

1. Create a MySQL User in remote server.

2. Give Full privilege to the User.

3. Connect to the Server using PHP Code (Sample Given Below)

$link = mysql_connect('your_my_sql_servername or IP Address', 'new_user_which_u_created', 'password');
if (!$link) {
    die('Could not connect: ' . mysql_error());
}

echo 'Connected successfully';

mysql_select_db('sandsbtob',$link) or die ("could not open db".mysql_error());
// we connect to localhost at port 3306

You can also use this library which wraps HttpWebRequest and Response into simple methods that return objects based on the results. It uses some of the techniques described in these answers and has plenty of code inspired by answers from this and similar threads. It automatically catches any exceptions, seeks to abstract as much boiler plate code needed to make these web requests as possible, and automatically deserializes the response object.

An example of what your code would look like using this wrapper is as simple as

    var response = httpClient.Get<SomeResponseObject>(request);
    
    if(response.StatusCode == HttpStatusCode.OK)
    {
        //do something with the response
        console.Writeline(response.Body.Id); //where the body param matches the object you pass in as an anonymous type.  
    }else {
         //do something with the error
         console.Writelint(string.Format("{0}: {1}", response.StatusCode.ToString(), response.ErrorMessage);

    }

Full disclosure This library is a free open source wrapper library, and I am the author of said library. I make no money off of this but have found it immensely useful over the years and am sure anyone who is still using the HttpWebRequest / HttpWebResponse classes will too.

It is not a silver bullet but supports get, post, delete with both async and non-async for get and post as well as JSON or XML requests and responses. It is being actively maintained as of 6/21/2020

This is an excerpt from method of mine, which converts a DataTable (the dt variable) into an array and then writes the array into a Range on a worksheet (wsh var). You can also change the topRow variable to whatever row you want the array of strings to be placed at.

object[,] arr = new object[dt.Rows.Count, dt.Columns.Count];
for (int r = 0; r < dt.Rows.Count; r++)
{
    DataRow dr = dt.Rows[r];
    for (int c = 0; c < dt.Columns.Count; c++)
    {
        arr[r, c] = dr[c];
    }
}
Excel.Range c1 = (Excel.Range)wsh.Cells[topRow, 1];
Excel.Range c2 = (Excel.Range)wsh.Cells[topRow + dt.Rows.Count - 1, dt.Columns.Count];
Excel.Range range = wsh.get_Range(c1, c2);
range.Value = arr;

Of course you do not need to use an intermediate DataTable like I did, the code excerpt is just to demonstrate how an array can be written to worksheet in single call.

Doing this with POSIX is tricky:

• POSIX Sed does not support \r or \15. Even if it did, the in place option -i is not POSIX

• POSIX Awk does support \r and \15, however the -i inplace option is not POSIX

• d2u and dos2unix are not POSIX utilities, but ex is

• POSIX ex does not support \r, \15, \n or \12

To remove carriage returns:

awk 'BEGIN{RS="^$";ORS="";getline;gsub("\r","");print>ARGV[1]}' file

To add carriage returns:

awk 'BEGIN{RS="^$";ORS="";getline;gsub("\n","\r&");print>ARGV[1]}' file

If you are using this to get a LINQ to SQL which I do and wanted for my Visual Developer, 1) get the free Visual WEB Developer, use that to connect to SQL Server instance, create your LINQ interface, then copy the generated files into your Vis-Dev project (I don't use VD because it sounds funny). Include only the *.dbml files. The Vis-Dev environment will take a second or two to recognize the supporting files. It is a little extra step but for sure better than doing it by hand or giving up on it altogether or EVEN WORSE, paying for it. Mooo ha ha haha.

Verify that Postgres is running using:

ps -ef | grep postgres

root@959dca34cc6d:/var/lib/edb# ps -ef|grep postgres
enterpr+    476  1  0 06:38 ?        00:00:00 /usr/lib/edb-as/11/bin/edb-postgres -D /var/lib/edb-as/11/main2 -c config_file=/etc/edb-as/11/main2/postgresql.conf

Check for data directory and postgresql.conf.

In my case data directory in -D was different than that in postgresql.conf

So I changed the data directory in postgresql.conf and it worked.

All you have to do is create a subset of your dataframe where the isin method evaluates to False:

If you are running windows 7 (professional) and Git for Windows (v 2.15 or above), you can simply run below command to find out what are different diff tools supported by your Git for Windows

git difftool --tool-help

You will see output similar to this

git difftool --tool=' may be set to one of the following:
vimdiff vimdiff2 vimdiff3

it means that your git does not support(can not find) beyond compare as difftool right now.

In order for Git to find beyond compare as valid difftool, you should have Beyond Compare installation directory in your system path environment variable. You can check this by running bcompare from shell(cmd, git bash or powershell. I am using Git Bash). If Beyond Compare does not launch, add its installation directory (in my case, C:\Program Files\Beyond Compare 4) to your system path variable. After this, restart your shell. Git will show Beyond Compare as possible difftool option. You can use any of below commands to launch beyond compare as difftool (for example, to compare any local file with some other branch)

git difftool -t bc branchnametocomparewith -- path-to-file
or 
git difftool --tool=bc branchnametocomparewith -- path-to-file

You can configure beyond compare as default difftool using below commands

   git config --global diff.tool bc

p.s. keep in mind that bc in above command can be bc3 or bc based upon what Git was able to find from your path system variable.

Yes , Jared and Kelly Orr are right. I use the following code like in edit exception.

}

in stead of

ModelState.AddRuleViolations(dinner.GetRuleViolations());

Note that if you don't specify an ORDER BY clause then any 10 rows could be returned, because "first 10 rows" doesn't really mean anything until you tell the database what ordering to use.

I extended ??s???? K's answer to make the code full and workable. So, when you finish filling your 'all_thumbs' list, you should put its content one by one into the bundle and then into the intent:

Bundle bundle = new Bundle();

for (int i = 0; i<all_thumbs.size(); i++)
bundle.putSerializable("extras"+i, all_thumbs.get(i));

intent.putExtras(bundle);

In order to get the extras from the intent, you need:

Bundle bundle = new Bundle();
List<Thumbnail> thumbnailObjects = new ArrayList<Thumbnail>();

// collect your Thumbnail objects
for (String key : bundle.keySet()) {
thumbnailObjects.add((Thumbnail) bundle.getSerializable(key));
}

// for example, in order to get a value of the 3-rd object you need to:
String label = thumbnailObjects.get(2).get_label();

Advantage of Serializable is its simplicity. However, I would recommend you to consider using Parcelable method when you need transfer many data, because Parcelable is specifically designed for Android and it is more efficient than Serializable. You can create Parcelable class using:

1. an online tool - parcelabler
2. a plugin for Android Studion - Android Parcelable code generator

Here's other example of taking top 3 on sorted order, and sorting within the groups:

In [43]: import pandas as pd                                                                                                                                                       

In [44]:  df = pd.DataFrame({"name":["Foo", "Foo", "Baar", "Foo", "Baar", "Foo", "Baar", "Baar"], "count_1":[5,10,12,15,20,25,30,35], "count_2" :[100,150,100,25,250,300,400,500]})

In [45]: df                                                                                                                                                                        
Out[45]: 
   count_1  count_2  name
0        5      100   Foo
1       10      150   Foo
2       12      100  Baar
3       15       25   Foo
4       20      250  Baar
5       25      300   Foo
6       30      400  Baar
7       35      500  Baar


### Top 3 on sorted order:
In [46]: df.groupby(["name"])["count_1"].nlargest(3)                                                                                                                               
Out[46]: 
name   
Baar  7    35
      6    30
      4    20
Foo   5    25
      3    15
      1    10
dtype: int64


### Sorting within groups based on column "count_1":
In [48]: df.groupby(["name"]).apply(lambda x: x.sort_values(["count_1"], ascending = False)).reset_index(drop=True)
Out[48]: 
   count_1  count_2  name
0       35      500  Baar
1       30      400  Baar
2       20      250  Baar
3       12      100  Baar
4       25      300   Foo
5       15       25   Foo
6       10      150   Foo
7        5      100   Foo

What have you tried? This should work.

h1 { font-size: 20pt; }
h2 { font-size: 16pt; }

break or goto

while ( true ) {
  if ( conditional ) {
    break;
  }
  if ( other conditional ) {
    goto EndWhile;
  }
}
EndWhile:

To send running process to nohup (http://en.wikipedia.org/wiki/Nohup)

nohup -p pid , it did not worked for me

Then I tried the following commands and it worked very fine

1. Run some SOMECOMMAND, say /usr/bin/python /vol/scripts/python_scripts/retention_all_properties.py 1.

2. Ctrl+Z to stop (pause) the program and get back to the shell.

3. bg to run it in the background.

4. disown -h so that the process isn't killed when the terminal closes.

5. Type exit to get out of the shell because now you're good to go as the operation will run in the background in its own process, so it's not tied to a shell.

This process is the equivalent of running nohup SOMECOMMAND.

if ($inputs['type'] == 'attach') {

The code is valid, but it expects the function parameter $inputs to be an array. The "Illegal string offset" warning when using $inputs['type'] means that the function is being passed a string instead of an array. (And then since a string offset is a number, 'type' is not suitable.)

So in theory the problem lies elsewhere, with the caller of the code not providing a correct parameter.

However, this warning message is new to PHP 5.4. Old versions didn't warn if this happened. They would silently convert 'type' to 0, then try to get character 0 (the first character) of the string. So if this code was supposed to work, that's because abusing a string like this didn't cause any complaints on PHP 5.3 and below. (A lot of old PHP code has experienced this problem after upgrading.)

You might want to debug why the function is being given a string by examining the calling code, and find out what value it has by doing a var_dump($inputs); in the function. But if you just want to shut the warning up to make it behave like PHP 5.3, change the line to:

if (is_array($inputs) && $inputs['type'] == 'attach') {

@article = user.articles.build(:title => "MainTitle")
@article.save

Why not to combine random.uniform with a list comprehension?

>>> def random_floats(low, high, size):
...    return [random.uniform(low, high) for _ in xrange(size)]
... 
>>> random_floats(0.5, 2.8, 5)

This answer is based off of Vainbhav Jain's answer.

One thing to be aware of is that many Linux netfilter firewalls are misconfigured.

If you have something like:

-A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT

-A FORWARD -p tcp -j REJECT --reject-with tcp-reset

then packet reordering can result in the firewall considering the packets invalid and thus generating resets which will then break otherwise healthy connections.

Reordering is particularly likely with a wireless network.

This should instead be:

-A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT

-A FORWARD -m state --state INVALID -j DROP

-A FORWARD -p tcp -j REJECT --reject-with tcp-reset

Basically anytime you have:

... -m state --state RELATED,ESTABLISHED -j ACCEPT

it should immediately be followed by:

... -m state --state INVALID -j DROP

It's better to drop a packet then to generate a potentially protocol disrupting tcp reset. Resets are better when they're provably the correct thing to send... since this eliminates timeouts. But if there's any chance they're invalid then they can cause this sort of pain.

Update for @angular/[email protected]: and over

In angular.json you can specify a port per "project"

"projects": {
    "my-cool-project": {
        ... rest of project config omitted
        "architect": {
            "serve": {
                "options": {
                    "port": 1337
                }
            }
        }
    }
}

All options available:

https://angular.io/guide/workspace-config#project-tool-configuration-options

Alternatively, you may specify the port each time when running ng serve like this:

ng serve --port 1337

With this approach you may wish to put this into a script in your package.json to make it easier to run each time / share the config with others on your team:

"scripts": {
    "start": "ng serve --port 1337"
}

Legacy:

Update for @angular/cli final:

Inside angular-cli.json you can specify the port in the defaults:

"defaults": {
  "serve": {
    "port": 1337
  }
}

Legacy-er:

Tested in [email protected]

The server in angular-cli comes from the ember-cli project. To configure the server, create an .ember-cli file in the project root. Add your JSON config in there:

{
   "port": 1337
}

Restart the server and it will serve on that port.

There are more options specified here: http://ember-cli.com/#runtime-configuration

{
  "skipGit" : true,
  "port" : 999,
  "host" : "0.1.0.1",
  "liveReload" : true,
  "environment" : "mock-development",
  "checkForUpdates" : false
}

Here is a solution with an stdout redirection:

def elevate():
    import ctypes, win32com.shell.shell, win32event, win32process
    outpath = r'%s\%s.out' % (os.environ["TEMP"], os.path.basename(__file__))
    if ctypes.windll.shell32.IsUserAnAdmin():
        if os.path.isfile(outpath):
            sys.stderr = sys.stdout = open(outpath, 'w', 0)
        return
    with open(outpath, 'w+', 0) as outfile:
        hProc = win32com.shell.shell.ShellExecuteEx(lpFile=sys.executable, \
            lpVerb='runas', lpParameters=' '.join(sys.argv), fMask=64, nShow=0)['hProcess']
        while True:
            hr = win32event.WaitForSingleObject(hProc, 40)
            while True:
                line = outfile.readline()
                if not line: break
                sys.stdout.write(line)
            if hr != 0x102: break
    os.remove(outpath)
    sys.stderr = ''
    sys.exit(win32process.GetExitCodeProcess(hProc))

if __name__ == '__main__':
    elevate()
    main()

If we need only one column to be numeric

yyz$b <- as.numeric(as.character(yyz$b))

But, if all the columns needs to changed to numeric, use lapply to loop over the columns and convert to numeric by first converting it to character class as the columns were factor.

yyz[] <- lapply(yyz, function(x) as.numeric(as.character(x)))

Both the columns in the OP's post are factor because of the string "n/a". This could be easily avoided while reading the file using na.strings = "n/a" in the read.table/read.csv or if we are using data.frame, we can have character columns with stringsAsFactors=FALSE (the default is stringsAsFactors=TRUE)

Regarding the usage of apply, it converts the dataset to matrix and matrix can hold only a single class. To check the class, we need

lapply(yyz, class)

Or

sapply(yyz, class)

Or check

str(yyz)

You can use resize like this:

For n = 1 To 5
    Columns(n).Resize(, 5).Select
    '~~> rest of your code
Next

In any Range Manipulation that you do, always keep at the back of your mind Resize and Offset property.

you can use QString::fromAscii()

QByteArray data = entity->getData();
QString s_data = QString::fromAscii(data.data());

with data() returning a char*

for QT5, you should use fromCString() instead, as fromAscii() is deprecated, see https://bugreports.qt-project.org/browse/QTBUG-21872 https://bugreports.qt.io/browse/QTBUG-21872

For those using PowerShell

PS C:\> Get-Content create.sql -Raw | sqlite3 auction.db

You can try to use that class. The limitation is that it can't be used outside of one process.

One activity:

 final Object obj1 = new Object();
 final Intent in = new Intent();
 in.putExtra(EXTRA_TEST, new Sharable(obj1));

Other activity:

final Sharable s = in.getExtras().getParcelable(EXTRA_TEST);
final Object obj2 = s.obj();

public final class Sharable implements Parcelable {

    private Object mObject;

    public static final Parcelable.Creator < Sharable > CREATOR = new Parcelable.Creator < Sharable > () {
        public Sharable createFromParcel(Parcel in ) {
            return new Sharable( in );
        }


        @Override
        public Sharable[] newArray(int size) {
            return new Sharable[size];
        }
    };

    public Sharable(final Object obj) {
        mObject = obj;
    }

    public Sharable(Parcel in ) {
        readFromParcel( in );
    }

    Object obj() {
        return mObject;
    }


    @Override
    public int describeContents() {
        return 0;
    }


    @Override
    public void writeToParcel(final Parcel out, int flags) {
        final long val = SystemClock.elapsedRealtime();
        out.writeLong(val);
        put(val, mObject);
    }

    private void readFromParcel(final Parcel in ) {
        final long val = in .readLong();
        mObject = get(val);
    }

    /////

    private static final HashMap < Long, Object > sSharableMap = new HashMap < Long, Object > (3);

    synchronized private static void put(long key, final Object obj) {
        sSharableMap.put(key, obj);
    }

    synchronized private static Object get(long key) {
        return sSharableMap.remove(key);
    }
}

I've had success with using white-space: nowrap; on the outer container, display: inline-block; on the inner containers, and then (in my case since I wanted the second one to word-wrap) white-space: normal; on the inner ones.

You need to store it in a String variable first before displaying it like so:

String Txt = TxtBoxContent.getText();
System.out.println(Txt);

Don't initialize variables in headers. Put declaration in header and initialization in one of the c files.

In the header:

extern int i;

In file2.c:

int i=1;

Going to provide a slightly different answer to those provided so far.

If you have a row for an anonymous user from localhost in your users table ''@'localhost' then this will be treated as more specific than your user with wildcard'd host 'user'@'%'. This is why it is necessary to also provide 'user'@'localhost'.

You can see this explained in more detail at the bottom of this page.

The below code address the question "How do I add n number of empty columns to my existing dataframe". In the interest of keeping solutions to similar problems in one place, I am adding it here.

Approach 1 (to create 64 additional columns with column names from 1-64)

m = list(range(1,65,1)) 
dd=pd.DataFrame(columns=m)
df.join(dd).replace(np.nan,'') #df is the dataframe that already exists

Approach 2 (to create 64 additional columns with column names from 1-64)

df.reindex(df.columns.tolist() + list(range(1,65,1)), axis=1).replace(np.nan,'')

I'm using this since the begin and it always work. =)

Update for transposition:

You should use cvTranspose() or cv::transpose() because (as you rightly pointed out) it's more efficient. Again, I recommend upgrading to OpenCV2.0 since most of the cvXXX functions just convert IplImage* structures to Mat objects (no deep copies). If you stored the image in a Mat object, Mat.t() would return the transpose.

Any rotation:

You should use cvWarpAffine by defining the rotation matrix in the general framework of the transformation matrix. I would highly recommend upgrading to OpenCV2.0 which has several features as well as a Mat class which encapsulates matrices and images. With 2.0 you can use warpAffine to the above.

try this:

SELECT ReportId, Email =

           FROM your_table b 
           WHERE b.ReportId = a.ReportId 
          FOR XML PATH('')), 1, 2, '')
FROM your_table a
GROUP BY ReportId

integrity - defines the hash value of a resource (like a checksum) that has to be matched to make the browser execute it. The hash ensures that the file was unmodified and contains expected data. This way browser will not load different (e.g. malicious) resources. Imagine a situation in which your JavaScript files were hacked on the CDN, and there was no way of knowing it. The integrity attribute prevents loading content that does not match.

Invalid SRI will be blocked (Chrome developer-tools), regardless of cross-origin. Below NON-CORS case when integrity attribute does not match:

Integrity can be calculated using: https://www.srihash.org/ Or typing into console (link):

openssl dgst -sha384 -binary FILENAME.js | openssl base64 -A

crossorigin - defines options used when the resource is loaded from a server on a different origin. (See CORS (Cross-Origin Resource Sharing) here: https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS). It effectively changes HTTP requests sent by the browser. If the “crossorigin” attribute is added - it will result in adding origin: <ORIGIN> key-value pair into HTTP request as shown below.

crossorigin can be set to either “anonymous” or “use-credentials”. Both will result in adding origin: into the request. The latter however will ensure that credentials are checked. No crossorigin attribute in the tag will result in sending a request without origin: key-value pair.

Here is a case when requesting “use-credentials” from CDN:

<script 
        src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/js/bootstrap.min.js"
        integrity="sha384-vBWWzlZJ8ea9aCX4pEW3rVHjgjt7zpkNpZk+02D9phzyeVkE+jo0ieGizqPLForn" 
        crossorigin="use-credentials"></script>

A browser can cancel the request if crossorigin incorrectly set.

I had this problem after changing the password for the root user in phpMyAdmin. I know nothing about programming but I solved it by doing the following:

1. Go to file C:\wamp\apps\phpmyadmin3.2.0.1\config.inc.php (I guess you would replace "wamp" with the name of your server if you're not using Wamp Server)

2. Find the line $cfg['Servers'][$i]['password']='' and change this to

   $cfg['Servers'][$i]['password']='NO'
   

3. Try opening phpMyAdmin again, and hopefully the message will now read "Access denied for user 'root'@'localhost' (using password: YES)

4. Now change the password in the above line to 'yourpassword' (whatever you had set it to before)

Hope this helps somebody.

Your problem can easily be solved by converting it to the object first. After it is converted to object, just use "astype" to convert it to str.

obj = lambda x:x[1:]
df['id']=df['id'].apply(obj).astype('str')

You can use a FileReader object to read text file here is example code:

  <div id="page-wrapper">

        <h1>Text File Reader</h1>
        <div>
            Select a text file: 
            <input type="file" id="fileInput">
        </div>
        <pre id="fileDisplayArea"><pre>

    </div>
<script>
window.onload = function() {
        var fileInput = document.getElementById('fileInput');
        var fileDisplayArea = document.getElementById('fileDisplayArea');

        fileInput.addEventListener('change', function(e) {
            var file = fileInput.files[0];
            var textType = /text.*/;

            if (file.type.match(textType)) {
                var reader = new FileReader();

                reader.onload = function(e) {
                    fileDisplayArea.innerText = reader.result;
                }

                reader.readAsText(file);    
            } else {
                fileDisplayArea.innerText = "File not supported!"
            }
        });
}

</script>

Here is the codepen demo

If you have a fixed file to read every time your application load then you can use this code :

<script>
var fileDisplayArea = document.getElementById('fileDisplayArea');
function readTextFile(file)
{
    var rawFile = new XMLHttpRequest();
    rawFile.open("GET", file, false);
    rawFile.onreadystatechange = function ()
    {
        if(rawFile.readyState === 4)
        {
            if(rawFile.status === 200 || rawFile.status == 0)
            {
                var allText = rawFile.responseText;
                fileDisplayArea.innerText = allText 
            }
        }
    }
    rawFile.send(null);
}

readTextFile("file:///C:/your/path/to/file.txt");
</script>

$result = preg_replace('/ /', '%20', 'your string here');

you may also consider using

$result = urlencode($yourstring)

to escape other special characters as well

Another way to assign a row number in a query is to use the DCount function.

SELECT *, DCount("[ID]","[mytable]","[ID]<=" & [ID]) AS row_id
FROM [mytable]
WHERE row_id=15

WHERE username LIKE '%[_]d';            -- @Lasse solution
WHERE username LIKE '%$_d' ESCAPE '$';
WHERE username LIKE '%^_d' ESCAPE '^';

Java doesn't want you to make an array of HashMaps, but it will let you make an array of Objects. So, just write up a class declaration as a shell around your HashMap, and make an array of that class. This lets you store some extra data about the HashMaps if you so choose--which can be a benefit, given that you already have a somewhat complex data structure.

What this looks like:

private static someClass[] arr = new someClass[someNum];

and

public class someClass {

private static int dataFoo;
private static int dataBar;
private static HashMap<String, String> yourArray;

...

}

This will add a path to your Python process / instance (i.e. the running executable). The path will not be modified for any other Python processes. Another running Python program will not have its path modified, and if you exit your program and run again the path will not include what you added before. What are you are doing is generally correct.

set.py:

import sys
sys.path.append("/tmp/TEST")

loop.py

import sys
import time
while True:
  print sys.path
  time.sleep(1)

run: python loop.py &

This will run loop.py, connected to your STDOUT, and it will continue to run in the background. You can then run python set.py. Each has a different set of environment variables. Observe that the output from loop.py does not change because set.py does not change loop.py's environment.

A note on importing

Python imports are dynamic, like the rest of the language. There is no static linking going on. The import is an executable line, just like sys.path.append....

Fix the permissions of the directory you try to create a directory in.
