Ray's solution is good. However, on my machine it is about 2.5x faster to use numpy.sum in place of numpy.min:

In [13]: %timeit np.isnan(np.min(x))
1000 loops, best of 3: 244 us per loop

In [14]: %timeit np.isnan(np.sum(x))
10000 loops, best of 3: 97.3 us per loop

Unlike min, sum doesn't require branching, which on modern hardware tends to be pretty expensive. This is probably the reason why sum is faster.

edit The above test was performed with a single NaN right in the middle of the array.

It is interesting to note that min is slower in the presence of NaNs than in their absence. It also seems to get slower as NaNs get closer to the start of the array. On the other hand, sum's throughput seems constant regardless of whether there are NaNs and where they're located:

In [40]: x = np.random.rand(100000)

In [41]: %timeit np.isnan(np.min(x))
10000 loops, best of 3: 153 us per loop

In [42]: %timeit np.isnan(np.sum(x))
10000 loops, best of 3: 95.9 us per loop

In [43]: x[50000] = np.nan

In [44]: %timeit np.isnan(np.min(x))
1000 loops, best of 3: 239 us per loop

In [45]: %timeit np.isnan(np.sum(x))
10000 loops, best of 3: 95.8 us per loop

In [46]: x[0] = np.nan

In [47]: %timeit np.isnan(np.min(x))
1000 loops, best of 3: 326 us per loop

In [48]: %timeit np.isnan(np.sum(x))
10000 loops, best of 3: 95.9 us per loop

i found out why my first row was default selected and found out how to not select it by default.

By default my datagridview was the object with the first tab-stop on my windows form. Making the tab stop first on another object (maybe disabling tabstop for the datagrid at all will work to) disabled selecting the first row

Subscribing to the IUS Community Project Repository

cd ~

Upgrading mod_php with Apache

This section describes the upgrade process for a system using Apache as the web server and mod_php to execute PHP code. If, instead, you are running Nginx and PHP-FPM, skip ahead to the next section.

Begin by removing existing PHP packages. Press y and hit Enter to continue when prompted.

sudo yum remove php-cli mod_php php-common

Install the new PHP 7 packages from IUS. Again, press y and Enter when prompted.

sudo yum install mod_php70u php70u-cli php70u-mysqlnd

Finally, restart Apache to load the new version of mod_php:

sudo apachectl restart

You can check on the status of Apache, which is managed by the httpd systemd unit, using systemctl:

systemctl status httpd

Elaborating a bit more on Taylor Gautier's reply (sorry, I dont have enough reputation to add a comment), I'd reply to Dean Richardson on how to do what he wanted, without any additional JS code. Pure CSS.

You would replace his .btn with the following:

<a class="btn showdetails" data-toggle="collapse" data-target="#viewdetails"></a>

And add a small CSS for when the content is displayed:

.in.collapse+a.btn.showdetails:before { 
    content:'Hide details «';
}
.collapse+a.btn.showdetails:before { 
    content:'Show details »'; 
}

Here is his modified example

No, this is not directly possible. The hash for every Git commit is also calculated based on the commit message. When you change the commit message, you change the commit hash. If you want to push that commit, you have to force that push (git push -f). But if already someone pulled your old commit and started a work based on that commit, he would have to rebase his work onto your new commit.

We have a different package name for debug builds (*.debug) so I wanted something that works based on flavor and buildType, without having to write anything flavor-related in the pattern of processDebugFlavorGoogleServices.

I created a folder named "google-services" in each flavor, containing both the debug version and the release version of the json file :

In the buildTypes section of your gradle file, add this :

    applicationVariants.all { variant ->
            def buildTypeName = variant.buildType.name
            def flavorName = variant.productFlavors[0].name;

            def googleServicesJson = 'google-services.json'
            def originalPath = "src/$flavorName/google-services/$buildTypeName/$googleServicesJson"
            def destPath = "."

            copy {
                if (flavorName.equals(getCurrentFlavor()) && buildTypeName.equals(getCurrentBuildType())) {
                    println originalPath
                    from originalPath
                    println destPath
                    into destPath
                }
            }
    }

It will copy the right json file at the root of your app module automatically when you'll switch build variant.

Add the two methods called to get the current flavor and current build type at the root of your build.gradle

def getCurrentFlavor() {
    Gradle gradle = getGradle()
    String  tskReqStr = gradle.getStartParameter().getTaskRequests().toString()

    Pattern pattern;

    if( tskReqStr.contains( "assemble" ) )
        pattern = Pattern.compile("assemble(\\w+)(Release|Debug)")
    else
        pattern = Pattern.compile("generate(\\w+)(Release|Debug)")

    Matcher matcher = pattern.matcher( tskReqStr )

    if( matcher.find() ) {
        println matcher.group(1).toLowerCase()
        return matcher.group(1).toLowerCase()
    }
    else
    {
        println "NO MATCH FOUND"
        return "";
    }
}

def getCurrentBuildType() {
    Gradle gradle = getGradle()
    String  tskReqStr = gradle.getStartParameter().getTaskRequests().toString()

        if (tskReqStr.contains("Release")) {
            println "getCurrentBuildType release"
            return "release"
        }
        else if (tskReqStr.contains("Debug")) {
            println "getCurrentBuildType debug"
            return "debug"
        }

    println "NO MATCH FOUND"
    return "";
}

That's it, you don't have to worry about removing/adding/modifying flavors from your gradle file, and it get the debug or the release google-services.json automatically.

Dim regDate As Date = Date.Now.date

This should fix your problem, though it's 2 years old!

ALL YOU HAVE TO DO:

HTML:

<table id="my-table"><tr>
<td> CELL 1 With a lot of text in it</td>
<td> CELL 2 </td>
<td> CELL 3 </td>
<td> CELL 4 With a lot of text in it </td>
<td> CELL 5 </td>
</tr></table>

CSS:

#my-table{width:100%;} /*or whatever width you want*/
#my-table td{width:2000px;} /*something big*/

if you have th you need to set it too like this:

#my-table th{width:2000px;}

Sorry to bump an old question but the answer is to count the character length of the cell and not its value.

CellCount = Cells(Row, 10).Value
If Len(CellCount) <= "13" Then
'do something
End If

hope that helps. Cheers

Swift Version

The easiest method is to set the tableFooterView property:

override func viewDidLoad() {
    super.viewDidLoad()
    // This will remove extra separators from tableview
    self.tableView.tableFooterView = UIView(frame: CGRectZero)
}

Your only option is to somehow clone the object.

See this stackoverflow question on how you can achieve this.

For simple JSON objects, the simplest way would be:

var newObject = JSON.parse(JSON.stringify(oldObject));

if you use jQuery, you can use:

// Shallow copy
var newObject = jQuery.extend({}, oldObject);

// Deep copy
var newObject = jQuery.extend(true, {}, oldObject);

UPDATE 2017: I should mention, since this is a popular answer, that there are now better ways to achieve this using newer versions of javascript:

In ES6 or TypeScript (2.1+):

var shallowCopy = { ...oldObject };

var shallowCopyWithExtraProp = { ...oldObject, extraProp: "abc" };

Note that if extraProp is also a property on oldObject, its value will not be used because the extraProp : "abc" is specified later in the expression, which essentially overrides it. Of course, oldObject will not be modified.

A TextBlock does not actually inherit from Control so it does not have properties that you would generally associate with a Control. Your best bet for adding a border in a style is to replace the TextBlock with a Label

See this link for more on the differences between a TextBlock and other Controls

LIKE should work in sqlite:

require(sqldf)
df <- data.frame(name = c('bob','robert','peter'),id=c(1,2,3))
sqldf("select * from df where name LIKE '%er%'")
    name id
1 robert  2
2  peter  3

Sorting a SortedDictionary list to bind into a ListView control using VB.NET:

Dim MyDictionary As SortedDictionary(Of String, MyDictionaryEntry)

MyDictionaryListView.ItemsSource = MyDictionary.Values.OrderByDescending(Function(entry) entry.MyValue)

Public Class MyDictionaryEntry ' Need Property for GridViewColumn DisplayMemberBinding
    Public Property MyString As String
    Public Property MyValue As Integer
End Class

XAML:

<ListView Name="MyDictionaryListView">
    <ListView.View>
        <GridView>
            <GridViewColumn DisplayMemberBinding="{Binding Path=MyString}" Header="MyStringColumnName"></GridViewColumn>
            <GridViewColumn DisplayMemberBinding="{Binding Path=MyValue}" Header="MyValueColumnName"></GridViewColumn>
         </GridView>
    </ListView.View>
</ListView>

Truth be told there are many, many resources explaining how to do this already out on the web:

Git: how to reverse-merge a commit?

Git: how to reverse-merge a commit?

Undoing Merges, from Git's blog (retrieved from archive.org's Wayback Machine)

So I guess I'll just summarize some of these:

1. git revert <merge commit hash>
   This creates an extra "revert" commit saying you undid a merge

2. git reset --hard <commit hash *before* the merge>
   This reset history to before you did the merge. If you have commits after the merge you will need to cherry-pick them on to afterwards.

But honestly this guide here is better than anything I can explain, with diagrams! :)

In addition to the other answers here, non-breaking spaces will not be "collapsed" like regular spaces will. For example:

<!-- Both -->
<p>Word1          Word2</p>
<!-- and -->
<p>Word1 Word2</p>
<!-- will render the same on any browser -->
<!-- While the below one will keep the spaces when rendered. -->
<p>Word1&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Word2</p>

Use .is(':checked') to determine whether or not it's checked, and then set your value accordingly.

More information here.

1. start cmd.exe and type:
2. Regsvr32 %dllpath%
3. "%dllpath%" replace to your dll path

I am using node version manager. I was getting this error message because I had switched to a different version of node. When I switched back to the version of node where I installed bower, this error went away. In my case, the command was nvm use stable

This can happen if you don't have mod_proxy_http enabled

sudo a2enmod proxy_http

For me to get my https based load balancer working, i had to enable the following:

sudo a2enmod ssl
sudo a2enmod proxy
sudo a2enmod proxy_balancer
sudo a2enmod proxy_http

I figured out the answer to above problem. Below query will return rows which have even a signle occurrence of characters besides alphabets, numbers, square brackets, curly brackets,s pace and dot. Please note that position of closing bracket ']' in matching pattern is important.

Right ']' has the special meaning of ending a character set definition. It wouldn't make any sense to end the set before you specified any members, so the way to indicate a literal right ']' inside square brackets is to put it immediately after the left '[' that starts the set definition

SELECT * FROM test WHERE REGEXP_LIKE(sampletext,  '[^]^A-Z^a-z^0-9^[^.^{^}^ ]' );

You can also Try this:

var results= persons.GroupBy(n => new { n.PersonId, n.car})
                .Select(g => new {
                               g.Key.PersonId,

If you are using XIB for tableView's main headerView you can set XIB as a freeform set the Height as you want and unclick Autoresizing's top,bottom blocks and upper,lower arrows.Only horizontal pieces will be selected.Vertical will be unselected as I mentioned above.

you can use this module -> https://github.com/jiahut/ng.lodash

this is for lodash so does underscore

Simply use the .toCharArray() method in Java:

String k = "abc";
char[] alpha = k.toCharArray();

This should work just fine in Java 8.

Using dict.popitem() in straightforward nested-list-like recursion:

def flatten(d):
    if d == {}:
        return d
    else:
        k,v = d.popitem()
        if (dict != type(v)):
            return {k:v, **flatten(d)}
        else:
            flat_kv = flatten(v)
            for k1 in list(flat_kv.keys()):
                flat_kv[k + '_' + k1] = flat_kv[k1]
                del flat_kv[k1]
            return {**flat_kv, **flatten(d)}

you can use also this way to write css for placeholder

input::placeholder{
   text-align: center;
}

Use a lambda function.

Let's say you have an array:

nums = [0,1,5]

Check whether 5 is in nums in Python 3.X:

(len(list(filter (lambda x : x == 5, nums))) > 0)

Check whether 5 is in nums in Python 2.7:

(len(filter (lambda x : x == 5, nums)) > 0)

This solution is more robust. You can now check whether any number satisfying a certain condition is in your array nums.

For example, check whether any number that is greater than or equal to 5 exists in nums:

(len(filter (lambda x : x >= 5, nums)) > 0)

You just need to add this line to the window there:

exec (your stored proc name) (and possibly add parameters)

What is your stored proc called, and what parameters does it expect?

You can put the filenames returned by find into an array like this:

array=()
while IFS=  read -r -d ''; do
    array+=("$REPLY")
done < <(find . -name '*.txt' -print0)

Now you can just loop through the array to access individual items and do whatever you want with them.

Note: It's white space safe.

This may help a small percentage of people still scratching their heads. Text copied from clipboard into VSCode may have an invisible hard space character preventing wrapping. Check it with HTML inspector

Use:

document.location.href = "http://yoursite.com" + document.getElementById('somefield');

That would get the value of some text field or hidden field, and add it to your site URL to get a new URL (href). You can modify this to suit your needs.

Try doing this :

awk '{print substr($0, 1, length($0)-1)}' file.txt

This is more generic than just removing the final comma but any last character

If you'd want to only remove the last comma with awk :

awk '{gsub(/,$/,""); print}' file.txt

Summary of solution:

directory is neither an existing file nor directory. As it turns out, the real name is directory.1 as revealed by ls -la $HOME/Desktop/.

The complete working command is

cp -R $HOME/directory.1/file.bundle /library/application\ support/directory/

with the -R parameter for recursive copy (compulsory for copying directories).

Though its very late reply, I have faced this problem of exporting java entites to CSV, EXCEL etc in various projects, Where we need to provide export feature on UI.

I have created my own light weight framework. It works with any Java Beans, You just need to add annotations on fields you want to export to CSV, Excel etc.

You have to specify the projectBaseDir if the module name doesn't match you module directory.

Since both your module are located in ".", you can simply add the following to your sonar-project properties:

module1.sonar.projectBaseDir=.
module2.sonar.projectBaseDir=.

Sonar will handle your modules as components of the project:

EDIT

If both of your modules are located in the same source directory, define the same source folder for both and exclude the unwanted packages with sonar.exclusions:

module1.sonar.sources=src/main/java
module1.sonar.exclusions=app2code/**/*

module2.sonar.sources=src/main/java
module2.sonar.exclusions=app1code/**/*

javac is the Java compiler. java is the JVM and what you use to execute a Java program. You do not execute .java files, they are just source files. Presumably there is .jar somewhere (or a directory containing .class files) that is the product of building it in Eclipse:

java/src/com/mypackage/Main.java
java/classes/com/mypackage/Main.class
java/lib/mypackage.jar

From directory java execute:

java -cp lib/mypackage.jar Main arg1 arg2

The answer appears to be solely related to application size. I created a simple "hello world" app with nothing special in the manifest file, uploaded it to the Play store, and it was reported as compatible with my device.

I changed nothing in this app except for adding more content into the res/drawable directory. When the .apk size reached about 32 MB, the Play store started reporting that my app was incompatible with my phone.

I will attempt to contact Google developer support and ask for clarification on the reason for this limit.

UPDATE: Here is Google developer support response to this:

Thank you for your note. Currently the maximum file size limit for an app upload to Google Play is approximately 50 MB.

However, some devices may have smaller than 50 MB cache partition making the app unavailable for users to download. For example, some of HTC Wildfire devices are known for having 35-40 MB cache partitions. If Google Play is able to identify such device that doesn't have cache large enough to store the app, it may filter it from appearing for the user.

I ended up solving my problem by converting all the PNG files to JPG, with a small loss of quality. The .apk file is now 28 MB, which is below whatever threshold Google Play is enforcing for my phone.

I also removed all the <uses-feature> stuff, and now have just this:

<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="15" />

I had the same problem on Ubuntu with Eclipse 4.3 (Kepler) and the problem was that I created the project with a minus-sign in it.

I recreated the project with no specialchars and it all worked fine

If you have char[] c then you can do char* d = &c[0] and access element c[1] by doing *(d+1), etc.

org.junit.Assert.assertEquals() and org.junit.Assert.assertArrayEquals() do the job.

To avoid next questions: If you want to ignore the order put all elements to set and then compare: Assert.assertEquals(new HashSet<String>(one), new HashSet<String>(two))

If however you just want to ignore duplicates but preserve the order wrap you list with LinkedHashSet.

Yet another tip. The trick Assert.assertEquals(new HashSet<String>(one), new HashSet<String>(two)) works fine until the comparison fails. In this case it shows you error message with to string representations of your sets that can be confusing because the order in set is almost not predictable (at least for complex objects). So, the trick I found is to wrap the collection with sorted set instead of HashSet. You can use TreeSet with custom comparator.

Regardless of whether I define this in the main CMakeLists.txt or in the individual ones, it still assumes I want all the libs and bins off the main path, which is the least useful assumption of all.

Getting the element type the jQuery way:

var elementType = $(this).prev().prop('nodeName');

doing the same without jQuery

var elementType = this.previousSibling.nodeName;

Checking for specific element type:

var is_element_input = $(this).prev().is("input"); //true or false

This is the solution that I came up with for this problem which works for me.

library used: momentjs with plain javascript Date class.

Step 1. Convert String date to moment object (PS: moment retains the original date and time as long as toDate() method is not called):

const dateMoment = moment("2005-07-08T11:22:33+0000");

Step 2. Extract hours and minutes values from the previously created moment object:

  const hours = dateMoment.hours();
  const mins = dateMoment.minutes();

Step 3. Convert moment to Date(PS: this will change the original date based on the timezone of your browser/machine, but don't worry and read step 4.):

  const dateObj = dateMoment.toDate();

Step 4. Manually set the hours and minutes extracted in Step 2.

  dateObj.setHours(hours);
  dateObj.setMinutes(mins);

Step 5. dateObj will now have show the original Date without any timezone difference. Even the Daylight time changes won't have any effect on the date object as we are manually setting the original hours and minutes.

Hope this helps.

You're looking for the /Y switch.

Alternatively, If you are using Apache then you can use .htaccess file to enforce your URLs to use https prefix. On Laravel 5.4, I added the following lines to my .htaccess file and it worked for me.

RewriteEngine On

RewriteCond %{HTTPS} !on
RewriteRule ^.*$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

The simplest solution is to add @Test annotated method to class where initialisation exception is present.

In our project we have main class with initial settings. I've added @Test method and exception has disappeared.

Boolean(val) === false. This worked for me to check if value was falsely.

I needed a query to return a large number of random rows from a rather large table. This is what I came up with. First get the maximum record id:

SELECT MAX(id) FROM table_name;

Then substitute that value into:

SELECT * FROM table_name WHERE id > FLOOR(RAND() * max) LIMIT n;

Where max is the maximum record id in the table and n is the number of rows you want in your result set. The assumption is that there are no gaps in the record id's although I doubt it would affect the result if there were (haven't tried it though). I also created this stored procedure to be more generic; pass in the table name and number of rows to be returned. I'm running MySQL 5.5.38 on Windows 2008, 32GB, dual 3GHz E5450, and on a table with 17,361,264 rows it's fairly consistent at ~.03 sec / ~11 sec to return 1,000,000 rows. (times are from MySQL Workbench 6.1; you could also use CEIL instead of FLOOR in the 2nd select statement depending on your preference)

DELIMITER $$

USE [schema name] $$

DROP PROCEDURE IF EXISTS `random_rows` $$

CREATE PROCEDURE `random_rows`(IN tab_name VARCHAR(64), IN num_rows INT)
BEGIN

SET @t = CONCAT('SET @max=(SELECT MAX(id) FROM ',tab_name,')');
PREPARE stmt FROM @t;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

SET @t = CONCAT(
    'SELECT * FROM ',
    tab_name,
    ' WHERE id>FLOOR(RAND()*@max) LIMIT ',
    num_rows);

PREPARE stmt FROM @t;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
END
$$

then

CALL [schema name].random_rows([table name], n);

Use os.path.abspath():

os.chdir(os.path.dirname(os.path.abspath(sys.argv[0])))

sys.argv[0] in your case is just a script name, no directory, so os.path.dirname() returns an empty string.

os.path.abspath() turns that into a proper absolute path with directory name.

Toolbar customization can done by following ways

write button and textViews code inside toolbar as shown below

<android.support.v7.widget.Toolbar
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/app_bar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >

    <Button
      android:layout_width="wrap_content"
        android:layout_height="@dimen/btn_height_small"
        android:text="Departure"
        android:layout_gravity="right"
        />
</android.support.v7.widget.Toolbar>

Other way is to use item menu as shown below

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

In my case I am using a CSS framework which adds box-shadow, so I had to also add

box-shadow: none;

So the complete snippet is:

border: none; 
border-width: 0; 
box-shadow: none;

The Bootstrap team seems to have removed it. See here: https://github.com/twbs/bootstrap/issues/8922 . @Skelly's answer involves custom css which I didn't want to do so I used the grid system and nav-pills. It worked fine and looked great. The code looks like so:

<div class="row">

  <!-- Navigation Buttons -->
  <div class="col-md-3">

GitHub's support determined the root of the issue right away: Two-factor authorization.

To use GitHub over the shell with https, create an OAuth token. As the page notes, I did have to remove my username and password credentials from Keychain but with osx-keychain in place, the token is stored as the password and things work exactly as they would over https without two-factor authorization in place.

The equation of a line is:

f(x) = A*x + b = y

For a segment, it is exactly the same, except that x is included on an interval I.

If you have two segments, defined as follow:

Segment1 = {(X1, Y1), (X2, Y2)}
Segment2 = {(X3, Y3), (X4, Y4)}

The abcisse Xa of the potential point of intersection (Xa,Ya) must be contained in both interval I1 and I2, defined as follow :

I1 = [min(X1,X2), max(X1,X2)]
I2 = [min(X3,X4), max(X3,X4)]

And we could say that Xa is included into :

Ia = [max( min(X1,X2), min(X3,X4) ),
      min( max(X1,X2), max(X3,X4) )]

Now, we need to check that this interval Ia exists :

if (max(X1,X2) < min(X3,X4)):
    return False  # There is no mutual abcisses

So, we have two line formula, and a mutual interval. Your line formulas are:

f1(x) = A1*x + b1 = y
f2(x) = A2*x + b2 = y

As we got two points by segment, we are able to determine A1, A2, b1 and b2:

A1 = (Y1-Y2)/(X1-X2)  # Pay attention to not dividing by zero
A2 = (Y3-Y4)/(X3-X4)  # Pay attention to not dividing by zero
b1 = Y1-A1*X1 = Y2-A1*X2
b2 = Y3-A2*X3 = Y4-A2*X4

If the segments are parallel, then A1 == A2 :

if (A1 == A2):
    return False  # Parallel segments

A point (Xa,Ya) standing on both line must verify both formulas f1 and f2:

Ya = A1 * Xa + b1
Ya = A2 * Xa + b2
A1 * Xa + b1 = A2 * Xa + b2
Xa = (b2 - b1) / (A1 - A2)   # Once again, pay attention to not dividing by zero

The last thing to do is check that Xa is included into Ia:

if ( (Xa < max( min(X1,X2), min(X3,X4) )) or
     (Xa > min( max(X1,X2), max(X3,X4) )) ):
    return False  # intersection is out of bound
else:
    return True

In addition to this, you may check at startup that two of the four provided points are not equals to avoid all that testing.

Edit: Just as a note, if you just need a quick and easy way of finding the distance between two points, I strongly recommend using the approach described in Kurt's answer below instead of re-implementing Haversine -- see his post for rationale.

This answer focuses just on answering the specific bug OP ran into.

It's because in Python, all the trig functions use radians, not degrees.

You can either convert the numbers manually to radians, or use the radians function from the math module:

from math import sin, cos, sqrt, atan2, radians

# approximate radius of earth in km
R = 6373.0

lat1 = radians(52.2296756)
lon1 = radians(21.0122287)
lat2 = radians(52.406374)
lon2 = radians(16.9251681)

dlon = lon2 - lon1
dlat = lat2 - lat1

a = sin(dlat / 2)**2 + cos(lat1) * cos(lat2) * sin(dlon / 2)**2
c = 2 * atan2(sqrt(a), sqrt(1 - a))

distance = R * c

print("Result:", distance)
print("Should be:", 278.546, "km")

The distance is now returning the correct value of 278.545589351 km.

Use an empty object literal isn't necessary here, you can use null or undefined:

$scope.items = null;

In this way, ng-show should keep working, and in your controller you can just do:

if ($scope.items) {
    // items have value
} else {
    // items is still null
}

And in your $http callbacks, you do the following:

$http.get(..., function(data) {
    $scope.items = {
        data: data,
        // other stuff
    };
});

Two other alternatives:

3. a combination of NULLIF and NVL2. You can only use this if emp_id is NOT NULL, which it is in your case:

   select nvl2(nullif(emp_id,1),'False','True') from employee;
   

4. simple CASE expression (Mt. Schneiders used a so-called searched CASE expression)

   select case emp_id when 1 then 'True' else 'False' end from employee;
   

Try this

#/bin/bash

read -p "Enter a word: " word
echo "You entered $word"

If your Local branch and remote branch is the same name then you can just do it:

git push origin branchName

When your local and remote branch name is different then you can just do it:

git push origin localBranchName:remoteBranchName

For me work ONLY this variant:

RewriteCond %{HTTPS} off
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Selenium can only automate on the WebElements of the browser. Opening a new tab is an operation performed on the webBrowser which is a stand alone application. For doing this you can make use of the Robot class from the java.util.* package which can perform operations using the keyboard regardless of what type of application it is. So here's the code for your operation. Note that you cannot automate stand alone applications using the Robot class but you can perform keyboard or mouse operations

System.setProperty("webdriver.chrome.driver","softwares\\chromedriver_win32\\chromedriver.exe"); 
WebDriver driver = new ChromeDriver();
driver.manage().timeouts().implicitlyWait(20,TimeUnit.SECONDS);
driver.manage().window().maximize();
driver.get("http://www.google.com");
Robot rob = new Robot();
rob.keyPress(keyEvent.VK_CONTROL);
rob.keyPress(keyEvent.VK_T);
rob.keyRelease(keyEvent.VK_CONTROL);
rob.keyRelease(keyEvent.VK_T);

After this step you will need a window iterator to switch to the new tab:

Set <String> ids = driver.getWindowHandles();
Iterator <String> it = ids.iterator();
String currentWindow = it.next();
String newWindow = it.next();
driver.switchTo().window(newWindow);
driver.findElement(By.linkText("www.facebook.com")).sendKeys(selectLinkOpeninNewTab);

Service vs provider vs factory:

I am trying to keep it simple. It's all about basic JavaScript concept.

First of all, let's talk about services in AngularJS!

What is Service: In AngularJS, Service is nothing but a singleton JavaScript object which can store some useful methods or properties. This singleton object is created per ngApp(Angular app) basis and it is shared among all the controllers within current app. When Angularjs instantiate a service object, it register this service object with a unique service name. So each time when we need service instance, Angular search the registry for this service name, and it returns the reference to service object. Such that we can invoke method, access properties etc on the service object. You may have question whether you can also put properties, methods on scope object of controllers! So why you need service object? Answers is: services are shared among multiple controller scope. If you put some properties/methods in a controller's scope object , it will be available to current scope only. But when you define methods, properties on service object, it will be available globally and can be accessed in any controller's scope by injecting that service.

So if there are three controller scope, let it be controllerA, controllerB and controllerC, all will share same service instance.

<div ng-controller='controllerA'>
    <!-- controllerA scope -->
</div>
<div ng-controller='controllerB'>
    <!-- controllerB scope -->
</div>
<div ng-controller='controllerC'>
    <!-- controllerC scope -->
</div>

How to create a service?

AngularJS provide different methods to register a service. Here we will concentrate on three methods factory(..),service(..),provider(..);

Use this link for code reference

Factory function:

We can define a factory function as below.

factory('serviceName',function fnFactory(){ return serviceInstance;})

AngularJS provides 'factory('serviceName', fnFactory)' method which takes two parameter, serviceName and a JavaScript function. Angular creates service instance by invoking the function fnFactory() such as below.

var serviceInstace = fnFactory();

The passed function can define a object and return that object. AngularJS simply stores this object reference to a variable which is passed as first argument. Anything which is returned from fnFactory will be bound to serviceInstance . Instead of returning object , we can also return function, values etc, Whatever we will return , will be available to service instance.

Example:

var app= angular.module('myApp', []);
//creating service using factory method
app.factory('factoryPattern',function(){
  var data={
    'firstName':'Tom',
    'lastName':' Cruise',
    greet: function(){
      console.log('hello!' + this.firstName + this.lastName);
    }
  };

  //Now all the properties and methods of data object will be available in our service object
  return data;
});

Service Function:

service('serviceName',function fnServiceConstructor(){})

It's the another way, we can register a service. The only difference is the way AngularJS tries to instantiate the service object. This time angular uses 'new' keyword and call the constructor function something like below.

var serviceInstance = new fnServiceConstructor();

In the constructor function we can use 'this' keyword for adding properties/methods to the service object. example:

//Creating a service using the service method
var app= angular.module('myApp', []);
app.service('servicePattern',function(){
  this.firstName ='James';
  this.lastName =' Bond';
  this.greet = function(){
    console.log('My Name is '+ this.firstName + this.lastName);
  };
});

Provider function:

Provider() function is the another way for creating services. Let we are interested to create a service which just display some greeting message to the user. But we also want to provide a functionality such that user can set their own greeting message. In technical terms we want to create configurable services. How can we do this ? There must be a way, so that app could pass their custom greeting messages and Angularjs would make it available to factory/constructor function which create our services instance. In such a case provider() function do the job. using provider() function we can create configurable services.

We can create configurable services using provider syntax as given below.

/*step1:define a service */
app.provider('service',function serviceProviderConstructor(){});

/*step2:configure the service */
app.config(function configureService(serviceProvider){});

How does provider syntax internally work?

1.Provider object is created using constructor function we defined in our provider function.

var serviceProvider = new serviceProviderConstructor();

2.The function we passed in app.config(), get executed. This is called config phase, and here we have a chance to customize our service.

configureService(serviceProvider);

3.Finally service instance is created by calling $get method of serviceProvider.

serviceInstance = serviceProvider.$get()

Sample code for creating service using provide syntax:

var app= angular.module('myApp', []);
app.provider('providerPattern',function providerConstructor(){
  //this function works as constructor function for provider
  this.firstName = 'Arnold ';
  this.lastName = ' Schwarzenegger' ;
  this.greetMessage = ' Welcome, This is default Greeting Message' ;
  //adding some method which we can call in app.config() function
  this.setGreetMsg = function(msg){
    if(msg){
      this.greetMessage =  msg ;
    }
  };

  //We can also add a method which can change firstName and lastName
  this.$get = function(){
    var firstName = this.firstName;
    var lastName = this.lastName ;
    var greetMessage = this.greetMessage;
    var data={
       greet: function(){
         console.log('hello, ' + firstName + lastName+'! '+ greetMessage);
       }
    };
    return data ;
  };
});

app.config(
  function(providerPatternProvider){
    providerPatternProvider.setGreetMsg(' How do you do ?');
  }
);

Working Demo

Summary:

Factory use a factory function which return a service instance. serviceInstance = fnFactory();

Service use a constructor function and Angular invoke this constructor function using 'new' keyword for creating the service instance. serviceInstance = new fnServiceConstructor();

Provider defines a providerConstructor function, this providerConstructor function defines a factory function $get . Angular calls $get() to create the service object. Provider syntax has an added advantage of configuring the service object before it get instantiated. serviceInstance = $get();

openssl allows to generate self-signed certificate by a single command (-newkey instructs to generate a private key and -x509 instructs to issue a self-signed certificate instead of a signing request)::

openssl req -x509 -newkey rsa:4096 \
-keyout my.key -passout pass:123456 -out my.crt \
-days 365 \
-subj /CN=localhost/O=home/C=US/[email protected] \
-addext "subjectAltName = DNS:localhost,DNS:web.internal,email:[email protected]" \
-addext keyUsage=digitalSignature -addext extendedKeyUsage=serverAuth

You can generate a private key and construct a self-signing certificate in separate steps::

openssl genrsa -out my.key -passout pass:123456 2048

openssl req -x509 \
-key my.key -passin pass:123456 -out my.csr \
-days 3650 \
-subj /CN=localhost/O=home/C=US/[email protected] \
-addext "subjectAltName = DNS:localhost,DNS:web.internal,email:[email protected]" \
-addext keyUsage=digitalSignature -addext extendedKeyUsage=serverAuth

Review the resulting certificate::

openssl x509 -text -noout -in my.crt

Java keytool creates PKCS#12 store::

keytool -genkeypair -keystore my.p12 -alias master \
-storetype pkcs12 -keyalg RSA -keysize 2048 -validity 3650 \
-storepass 123456 \
-dname "CN=localhost,O=home,C=US" \
-ext 'san=dns:localhost,dns:web.internal,email:[email protected]'

To export the self-signed certificate::

keytool -exportcert -keystore my.p12 -file my.crt \
-alias master -rfc -storepass 123456

Review the resulting certificate::

keytool -printcert -file my.crt

certtool from GnuTLS doesn't allow passing different attributes from CLI. I don't like to mess with config files ((

You can simulate them for example with hashes, but need care about the leading zeroes and many other things. The next demonstration works, but it is far from optimal solution.

#!/bin/bash
declare -A matrix
num_rows=4
num_columns=5

for ((i=1;i<=num_rows;i++)) do
    for ((j=1;j<=num_columns;j++)) do
        matrix[$i,$j]=$RANDOM
    done
done

f1="%$((${#num_rows}+1))s"
f2=" %9s"

printf "$f1" ''
for ((i=1;i<=num_rows;i++)) do
    printf "$f2" $i
done
echo

for ((j=1;j<=num_columns;j++)) do
    printf "$f1" $j
    for ((i=1;i<=num_rows;i++)) do
        printf "$f2" ${matrix[$i,$j]}
    done
    echo
done

the above example creates a 4x5 matrix with random numbers and print it transposed, with the example result

           1         2         3         4
 1     18006     31193     16110     23297
 2     26229     19869      1140     19837
 3      8192      2181     25512      2318
 4      3269     25516     18701      7977
 5     31775     17358      4468     30345

The principle is: Creating one associative array where the index is an string like 3,4. The benefits:

• it's possible to use for any-dimension arrays ;) like: 30,40,2 for 3 dimensional.
• the syntax is close to "C" like arrays ${matrix[2,3]}

Just for completeness: Xlib - But it's somewhat slow when capturing the whole screen:

from Xlib import display, X
import Image #PIL

W,H = 200,200
dsp = display.Display()
try:
    root = dsp.screen().root
    raw = root.get_image(0, 0, W,H, X.ZPixmap, 0xffffffff)
    image = Image.fromstring("RGB", (W, H), raw.data, "raw", "BGRX")
    image.show()
finally:
    dsp.close()

One could try to trow some types in the bottleneck-files in PyXlib, and then compile it using Cython. That could increase the speed a bit.

Edit: We can write the core of the function in C, and then use it in python from ctypes, here is something I hacked together:

#include <stdio.h>
#include <X11/X.h>
#include <X11/Xlib.h>
//Compile hint: gcc -shared -O3 -lX11 -fPIC -Wl,-soname,prtscn -o prtscn.so prtscn.c

void getScreen(const int, const int, const int, const int, unsigned char *);
void getScreen(const int xx,const int yy,const int W, const int H, /*out*/ unsigned char * data) 
{
   Display *display = XOpenDisplay(NULL);
   Window root = DefaultRootWindow(display);

   XImage *image = XGetImage(display,root, xx,yy, W,H, AllPlanes, ZPixmap);

   unsigned long red_mask   = image->red_mask;
   unsigned long green_mask = image->green_mask;
   unsigned long blue_mask  = image->blue_mask;
   int x, y;
   int ii = 0;
   for (y = 0; y < H; y++) {
       for (x = 0; x < W; x++) {
         unsigned long pixel = XGetPixel(image,x,y);
         unsigned char blue  = (pixel & blue_mask);
         unsigned char green = (pixel & green_mask) >> 8;
         unsigned char red   = (pixel & red_mask) >> 16;

         data[ii + 2] = blue;
         data[ii + 1] = green;
         data[ii + 0] = red;
         ii += 3;
      }
   }
   XDestroyImage(image);
   XDestroyWindow(display, root);
   XCloseDisplay(display);
}

And then the python-file:

import ctypes
import os
from PIL import Image

LibName = 'prtscn.so'
AbsLibPath = os.path.dirname(os.path.abspath(__file__)) + os.path.sep + LibName
grab = ctypes.CDLL(AbsLibPath)

def grab_screen(x1,y1,x2,y2):
    w, h = x2-x1, y2-y1
    size = w * h
    objlength = size * 3

    grab.getScreen.argtypes = []
    result = (ctypes.c_ubyte*objlength)()

    grab.getScreen(x1,y1, w, h, result)
    return Image.frombuffer('RGB', (w, h), result, 'raw', 'RGB', 0, 1)
    
if __name__ == '__main__':
  im = grab_screen(0,0,1440,900)
  im.show()

Delete the persistent store file and setup a new persistent store coordinator?

The creators of java decided that the problems of multiple inheritance outweigh the benefits, so they did not include multiple inheritance. You can read about one of the largest issues of multiple inheritance (the double diamond problem) here.

The two most similar concepts are interface implementation and including objects of other classes as members of the current class. Using default methods in interfaces is almost exactly the same as multiple inheritance, however it is considered bad practice to use an interface with only default methods.

There are two problems in your code:

• the return value of scanf must be checked
• the %d conversion does not take overflows into account (blindly applying *10 + newdigit for each consecutive numeric character)

The first value you got (-104204697) is equals to 5623125698541159 modulo 2^32; it is thus the result of an overflow (if int where 64 bits wide, no overflow would happen). The next values are uninitialized (garbage from the stack) and thus unpredictable.

The code you need could be (similar to the answer of BLUEPIXY above, with the illustration how to check the return value of scanf, the number of items successfully matched):

#include <stdio.h>

int main(int argc, char *argv[]) {
    int i, j;
    short unsigned digitArray[16];
    i = 0;
    while (
        i != sizeof(digitArray) / sizeof(digitArray[0])
     && 1 == scanf("%1hu", digitArray + i)
    ) {
        i++;
    }
    for (j = 0; j != i; j++) {
        printf("%hu\n", digitArray[j]);
    }
    return 0;
}

http://dev.mysql.com/doc/refman/5.0/en/insert-select.html

For case1:

INSERT INTO TAB_STUDENT(name_student, id_teacher_fk)
SELECT 'Joe The Student', id_teacher
  FROM TAB_TEACHER
 WHERE name_teacher = 'Professor Jack'
 LIMIT 1

For case2 you just have to do 2 separate insert statements

Yes, use INSERT ... ON DUPLICATE KEY UPDATE id=id (it won't trigger row update even though id is assigned to itself).

If you don't care about errors (conversion errors, foreign key errors) and autoincrement field exhaustion (it's incremented even if the row is not inserted due to duplicate key), then use INSERT IGNORE.

There is: Path.ChangeExtension method. E.g.:

var result = Path.ChangeExtension(myffile, ".jpg");

In the case if you also want to physically change the extension, you could use File.Move method:

File.Move(myffile, Path.ChangeExtension(myffile, ".jpg"));

Installers: win32-7.1.18-0-VC14-installer / xampp-windows-x64-7.3.7-0-VC15-installer

1. Do not edit other files like httpd-xampp

2. Stop Apache

3. Open httpd-vhosts.conf located in **your_xampp_directory**\apache\conf\extra\ (your XAMPP directory might be by default: C:/xampp/htdocs)

4. Remove hash before the following line (aprox. line 20): NameVirtualHost *:80 (this might be optional)

5. Add the following virtual hosts at the end of the file, considering your directories paths:

   ##127.0.0.1
   <VirtualHost *:80>
       DocumentRoot "C:/xampp/htdocs"
       ServerName localhost
       ErrorLog "logs/localhost-error.log"
       CustomLog "logs/localhost-access.log" common
   </VirtualHost>

           #AllowOverride All # Deprecated
           Require all granted  
       </Directory>
   </VirtualHost>
   

6. Edit (with admin access) your host file (located at Windows\System32\drivers\etc, but with the following tip, only one loopback ip for every domain:

   127.0.0.1 localhost
   127.0.0.2 test1.localhost
   127.0.0.2 www.test1.localhost

            long times = timeComparison(list2, list2)
                    + timeComparison(set2, set2)
                    + timeComparison(map2.keySet(), map2.keySet())
                    + timeComparison(map2.values(), map2.values());
            if (i > 0)

            compareCollections(a, b);
        long rate = (System.nanoTime() - start) / runs;
        return rate;

    public static void compareCollections(Collection a, Collection b) {
        if (!a.equals(b) && a.hashCode() != b.hashCode() && !a.toString().equals(b.toString()))

Here's the GNU version of printf... you can see it passing in stdout to vfprintf:

__printf (const char *format, ...)
{
   va_list arg;
   int done;

   va_start (arg, format);
   done = vfprintf (stdout, format, arg);
   va_end (arg);

   return done;
}

See here.

Here's a link to vfprintf... all the formatting 'magic' happens here.

The only thing that's truly 'different' about these functions is that they use varargs to get at arguments in a variable length argument list. Other than that, they're just traditional C. (This is in contrast to Pascal's printf equivalent, which is implemented with specific support in the compiler... at least it was back in the day.)

To actually do it in HTML with inline CSS (not with an external CSS style sheet)

<input type="text" style="font-size: 44pt">

A lot of people would consider putting the style right into the html like this to be poor form. However, I frequently make extreeemly simple web pages for my own use that don't even have a <html> or <body> tag, and such is appropriate there.

I believe using the format function is a bad idea. Please see the below. It rounds the value. I use Python 3.6.

>>> '%.3f'%(1.9999999)
'2.000'

Use a regular expression instead:

>>> re.match(r'\d+.\d{3}', str(1.999999)).group(0)
'1.999'

Maybe use System.arraycopy

public static byte[] merge(byte[] first, byte[] second){
    int len = first.length + second.length;
    byte[] full = new byte[len];
    System.arraycopy(first, 0, full, 0, first.length);
    System.arraycopy(second, 0, full, first.length, second.length);
    return full;
}

You can also try following,

long lg;
String Str = "1333073704000"
lg = Long.parseLong(Str);

The runas command does not allow a password on its command line. This is by design (and also the reason you cannot pipe a password to it as input). Raymond Chen says it nicely:

The RunAs program demands that you type the password manually. Why doesn't it accept a password on the command line?

This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts, which is laughably insecure.

In other words, the feature is missing to remove the temptation to use the feature insecurely.

tail -f /path/to/glassfish/domains/YOURDOMAIN/logs/server.log

You can also upload log from admin console : http://yoururl:4848

Sub DeleteEmptyRows()  

    Worksheets("YourSheetName").Activate
    On Error Resume Next
    Columns("A").SpecialCells(xlCellTypeBlanks).EntireRow.Delete

End Sub

The following code will delete all rows on a sheet(YourSheetName) where the content of Column A is blank.

EDIT: User Defined Type Not Defined is caused by "oTable As Table" and "oRow As Row". Replace Table and Row with Object to resolve the error and make it compile.

MongoDB can be confusing regarding the dbPath folder.

When you run mongod without dbpath then the default path is /data/db

However when you start it as a service, e.g. systemctl start mongod then it reads on configuration file, typially /etc/mongod.cfg and in this config file the defaults are

So, by accident your MongoDB tries to access different data folders depending on how you start the service.

Which is better, a or b?

From a performance perspective, you'd have to measure it. (And in my opinion, if you can measure a difference, the compiler isn't very good).

From a maintenance perspective, b is better. Declare and initialize variables in the same place, in the narrowest scope possible. Don't leave a gaping hole between the declaration and the initialization, and don't pollute namespaces you don't need to.

you have id="#message"... should be id="message"

Liquid XML Studio has an XML Sample Generator wizard which will build sample XML files from an XML Schema. The resulting data seems to comply with the schema (it just can't generate data for regex patterns).

A late answer, but and approach using data.table

library(data.table)
DT <- data.table(dat)

DT[, .SD[which.max(Score),], by = Group]

Or, if it is possible to have more than one equally highest score

DT[, .SD[which(Score == max(Score)),], by = Group]

Noting that (from ?data.table

.SD is a data.table containing the Subset of x's Data for each group, excluding the group column(s)

Use du -sb:

du -sb DIR

Optionally, add the h option for more user-friendly output:

du -sbh DIR

cmd /c "command" syntax works well. Also, if you want to include an executable that contains a space in the path, you will need two sets of quotes.

cmd /c ""path to executable""

and if your executable needs a file input with a space in the path a another set

cmd /c ""path to executable" -f "path to file"" 

The python docs recommend this way:

with open('file_to_write', 'w') as f:
    f.write('file contents\n')

So this is the way I usually do it :)

Statement from docs.python.org:

It is good practice to use the 'with' keyword when dealing with file objects. This has the advantage that the file is properly closed after its suite finishes, even if an exception is raised on the way. It is also much shorter than writing equivalent try-finally blocks.

As @avp says the bash line pip install seaborn should work I just had the same problem and and restarting the notebook didn't seem to work but running the command as jupyter line magic was a neat way to fix the problem without restarting the notebook

pip install seaborn

The frameworks directory is as follow in my computer: /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/System/Library/Frameworks

not the directory

/Developer/SDKs/MacOSXversion.sdk/System/Library/Frameworks

Why don't you try to grep the return of your command ? Something like :

adb devices -l | grep 123abc12

It should return only the line you want to.

You can use Random.Next(int maxValue):

Return: A 32-bit signed integer greater than or equal to zero, and less than maxValue; that is, the range of return values ordinarily includes zero but not maxValue. However, if maxValue equals zero, maxValue is returned.

var r = new Random();
// print random integer >= 0 and  < 100
Console.WriteLine(r.Next(100));

For this case however you could use Random.Next(int minValue, int maxValue), like this:

// print random integer >= 1 and < 101
Console.WriteLine(r.Next(1, 101);)
// or perhaps (if you have this specific case)
Console.WriteLine(r.Next(100) + 1);

I had the same problem. It turns out that I had both "MyPage.aspx" and "Copy of MyPage.aspx" in my project.

No, there is no other way than

def dictMinus(dct, val):
   copy = dct.copy()
   del copy[val]
   return copy

However, often creating copies of only slightly altered dictionaries is probably not a good idea because it will result in comparatively large memory demands. It is usually better to log the old dictionary(if even necessary) and then modify it.

As google says:

Paste it into your web page, just before the closing </head> tag.

One of the main advantages of the asynchronous snippet is that you can position it at the top of the HTML document. This increases the likelihood that the tracking beacon will be sent before the user leaves the page. It is customary to place JavaScript code in the <head> section, and we recommend placing the snippet at the bottom of the <head> section for best performance

So please make sure

1. No syntax error in directives

2. Browser (in App Module) and Common (in other/child) Modules are imported (Same what Günter Zöchbauer mentioned above)

3. If you've routes in the application then route module should be imported in App Module

4. All the routed component's Module are also imported in App Module, for eg: app-routing.module.ts is as follows:

   const routes: Routes = [

   {path: '', component: CustomerComponent},

   {path: 'admin', component: AdminComponent}

   ];

Then App module must imports modules of CustomerComponent and AdminComponent in @NgModule().

The problem is that [...] in python has two distinct meanings

1. expr [ index ] means accessing an element of a list
2. [ expr1, expr2, expr3 ] means building a list of three elements from three expressions

In your code you forgot the comma between the expressions for the items in the outer list:

[ [a, b, c] [d, e, f] [g, h, i] ]

therefore Python interpreted the start of second element as an index to be applied to the first and this is what the error message is saying.

The correct syntax for what you're looking for is

[ [a, b, c], [d, e, f], [g, h, i] ]

You need to use bindValue, not bindParam

bindParam takes a variable by reference, and doesn't pull in a value at the time of calling bindParam. I found this in a comment on the PHP docs:

bindValue(':param', null, PDO::PARAM_INT);

P.S. You may be tempted to do this bindValue(':param', null, PDO::PARAM_NULL); but it did not work for everybody (thank you Will Shaver for reporting.)

"We can break the $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration."

You can't have a link to SCSS File in your HTML page.You have to compile it down to CSS First. No there are lots of video tutorials you might want to check out. Lynda provides great video tutorials on SASS. there are also free screencasts you can google...

For official documentation visit this site http://sass-lang.com/documentation/file.SASS_REFERENCE.html And why have you chosen notepad to write Sass?? you can easily download some free text editors for better code handling.

Yes, you can use jQuery to make this done, the idea is

Use a hidden value in your form, and copy the value from external text box to this hidden value just before submitting the form.

<form name="input" action="handle_email.php" method="post">
  <input type="hidden" name="email" id="email" />
  <input type="submit" value="Submit" />
</form> 

<script>
   $("form").submit(function() {
     var emailFromOtherTextBox = $("#email_textbox").val();
     $("#email").val(emailFromOtherTextBox ); 
     return true;
  });
</script>

If you want to do it using Pentaho DI, you can use "Modified JavaScript" Step and write the below function:

dateAdd(d1, "d", -7);  // d1 is the current date and "d" is the date identifier

Check the image below: [Assuming current date is : 22 December 2014]

Hope it helps :)

What you have to do is to set the MinimumHeight property of the row. Not only the Height property. That's the key. Put the code bellow in the CellPainting event of the datagridview

private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
   foreach(DataGridViewRow x in dataGridView1.Rows)
   {
     x.MinimumHeight = 50;
   }
}

This is the definitive regex:

\(
(?<arguments> 
(  
  ([^\(\)']*) |  
  (\([^\(\)']*\)) |
  '(.*?)'

)*
)
\)

Example:

input: ( arg1, arg2, arg3, (arg4), '(pip' )

output: arg1, arg2, arg3, (arg4), '(pip'

note that the '(pip' is correctly managed as string. (tried in regulator: http://sourceforge.net/projects/regulator/)

You can create a class based on a Button with specific images for MouseHover and MouseDown like this:

public class AdvancedImageButton : Button {

public Image HoverImage { get; set; }
public Image PlainImage { get; set; }
public Image PressedImage { get; set; }

protected override void OnMouseEnter(System.EventArgs e)
{
  base.OnMouseEnter(e);
  if (HoverImage == null) return;
  if (PlainImage == null) PlainImage = base.Image;
  base.Image = HoverImage;
}

protected override void OnMouseLeave(System.EventArgs e)
{
  base.OnMouseLeave(e);
  if (HoverImage == null) return;
  base.Image = PlainImage;
}

protected override void OnMouseDown(MouseEventArgs e)
{
  base.OnMouseDown(e);
  if (PressedImage == null) return;
  if (PlainImage == null) PlainImage = base.Image;
  base.Image = PressedImage;
}

}

This solution has a small drawback that I am sure can be fixed: when you need for some reason change the Image property, you will also have to change the PlainImage property also.

At the beginning of your main method, add this line of code :

final long startTime = System.nanoTime();

And then, at the last line of your main method, you can add :

final long duration = System.nanoTime() - startTime;

duration now contains the time in nanoseconds that your program ran. You can for example print this value like this:

System.out.println(duration);

If you want to show duration time in seconds, you must divide the value by 1'000'000'000. Or if you want a Date object: Date myTime = new Date(duration / 1000); You can then access the various methods of Date to print number of minutes, hours, etc.

Using Authorize attribute seems more convenient and feels more 'MVC way'. As for technical advantages there are some.

One scenario that comes to my mind is when you're using output caching in your app. Authorize attribute handles that well.

Another would be extensibility. The Authorize attribute is just basic out of the box filter, but you can override its methods and do some pre-authorize actions like logging etc. I'm not sure how you would do that through configuration.

 INSERT INTO table (a,b) VALUES (1,2), (2,3), (3,4);

http://dev.mysql.com/doc/refman/5.5/en/insert.html

Give in the xml file of your layout android:scaleType="fitXY"
P.S : this applies to when the image is set with android:src="..." rather than android:background="..." as backgrounds are set by default to stretch and fit to the View.

I think using try/catch pattern is not very well for performance. I advice to use this:

public static boolean appInstalledOrNot(Context context, String uri) {
    PackageManager pm = context.getPackageManager();
    List<PackageInfo> packageInfoList = pm.getInstalledPackages(PackageManager.GET_ACTIVITIES);
    if (packageInfoList != null) {
        for (PackageInfo packageInfo : packageInfoList) {
            String packageName = packageInfo.packageName;
            if (packageName != null && packageName.equals(uri)) {
                return true;
            }
        }
    }
    return false;
}

You can also do it like this:

BigDecimal A = new BigDecimal("10000000000");
BigDecimal B = new BigDecimal("20000000000");
BigDecimal C = new BigDecimal("30000000000");
BigDecimal resultSum = (A).add(B).add(C);
System.out.println("A+B+C= " + resultSum);

Prints:

A+B+C= 60000000000

Got better solution:

$('#element').resizable({
    stop: function( event, ui ) {
        $('#element').height(ui.originalSize.height);
    }
});

For ES6/ES2015 you can import directly like:

// example.json
{
    "name": "testing"
}


// ES6/ES2015
// app.js
import * as data from './example.json';
const word = data.name;
console.log(word); // output 'testing'

If you use typescript, you may declare json module like:

// tying.d.ts
declare module "*.json" {
    const value: any;
    export default value;
}

Some browsers igoners sending leading zero to the server when the input type is "number". So I use a mixing of jquery and html to load a numeric keypad and also make sure that the value is sent as a text not as a number:

$(document).ready(function(){_x000D_
$(".numberonly").focus(function(){$(this).attr("type","number")});_x000D_
$(".numberonly").blur(function(){$(this).attr("type","text")});_x000D_
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input type="text" class="numberonly">

I understand that this is fairly old question and has some pretty good answers. But, here is my two cents for the sake of completeness.

As per the official documentation, there are four ways, you can allow complete access for robots to access your site.

Clean:

Specify a global matcher with a disallow segment as mentioned by @unor. So your /robots.txt looks like this.

User-agent: *
Disallow:

The hack:

Create a /robots.txt file with no content in it. Which will default to allow all for all type of Bots.

I don't care way:

Do not create a /robots.txt altogether. Which should yield the exact same results as the above two.

The ugly:

From the robots documentation for meta tags, You can use the following meta tag on all your pages on your site to let the Bots know that these pages are not supposed to be indexed.

<META NAME="ROBOTS" CONTENT="NOINDEX">

In order for this to be applied to your entire site, You will have to add this meta tag for all of your pages. And this tag should strictly be placed under your HEAD tag of the page. More about this meta tag here.

One way of doing it is to draw the image to a bitmap context that is backed by a given buffer for a given colorspace (in this case it is RGB): (note that this will copy the image data to that buffer, so you do want to cache it instead of doing this operation every time you need to get pixel values)

See below as a sample:

// First get the image into your data buffer
CGImageRef image = [myUIImage CGImage];
NSUInteger width = CGImageGetWidth(image);
NSUInteger height = CGImageGetHeight(image);
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
unsigned char *rawData = malloc(height * width * 4);
NSUInteger bytesPerPixel = 4;
NSUInteger bytesPerRow = bytesPerPixel * width;
NSUInteger bitsPerComponent = 8;
CGContextRef context = CGBitmapContextCreate(rawData, width, height, bitsPerComponent, bytesPerRow, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big);
CGColorSpaceRelease(colorSpace);

CGContextDrawImage(context, CGRectMake(0, 0, width, height));
CGContextRelease(context);

// Now your rawData contains the image data in the RGBA8888 pixel format.
int byteIndex = (bytesPerRow * yy) + xx * bytesPerPixel;
red = rawData[byteIndex];
green = rawData[byteIndex + 1];
blue = rawData[byteIndex + 2];
alpha = rawData[byteIndex + 3];

Please read the Android Documentation regarding screen sizes.

From a base image size, there is a 3:4:6:8:12:16 scaling ratio in drawable size by DPI.

LDPI - 0.75x
MDPI - Original size // means 1.0x here 
HDPI - 1.5x
XHDPI - 2.0x
XXHDPI - 3x
XXXHDPI - 4.0x

For example, 100x100px image on a MDPI will be the same size of a 200x200px on a XHDPI screen.

Not tested, but probably something like if(preg_match("/^[0-9,]+$/", $a)) $a = str_replace(...)

Do it the other way around:

$a = "1,435";
$b = str_replace( ',', '', $a );

if( is_numeric( $b ) ) {
    $a = $b;
}

The easiest would be:

$var = intval(preg_replace('/[^\d.]/', '', $var));

or if you need float:

$var = floatval(preg_replace('/[^\d.]/', '', $var));

specify @JsonProperty in entity class constructor like this.

......
......
......

 @JsonCreator
 public Location(@JsonProperty("sl_no") Long sl_no, 
          @JsonProperty("location")String location,
          @JsonProperty("location_type") String 
          location_type,@JsonProperty("store_sl_no")Long store_sl_no) {
  this.sl_no = sl_no;
  this.location = location;
  this.location_type = location_type;
  this.store_sl_no = store_sl_no;
 }

There are many JSON libraries available in Java.

The most notorious ones are: Jackson, GSON, Genson, FastJson and org.json.

There are typically three things one should look at for choosing any library:

1. Performance
2. Ease of use (code is simple to write and legible) - that goes with features.
3. For mobile apps: dependency/jar size

Specifically for JSON libraries (and any serialization/deserialization libs), databinding is also usually of interest as it removes the need of writing boiler-plate code to pack/unpack the data.

For 1, see this benchmark: https://github.com/fabienrenaud/java-json-benchmark I did using JMH which compares (jackson, gson, genson, fastjson, org.json, jsonp) performance of serializers and deserializers using stream and databind APIs. For 2, you can find numerous examples on the Internet. The benchmark above can also be used as a source of examples...

Quick takeaway of the benchmark: Jackson performs 5 to 6 times better than org.json and more than twice better than GSON.

For your particular example, the following code decodes your json with jackson:

public class MyObj {

    private PageInfo pageInfo;
    private List<Post> posts;

    static final class PageInfo {
        private String pageName;
        private String pagePic;
    }

    static final class Post {
        private String post_id;
        @JsonProperty("actor_id");
        private String actorId;
        @JsonProperty("picOfPersonWhoPosted")
        private String pictureOfPoster;
        @JsonProperty("nameOfPersonWhoPosted")
        private String nameOfPoster;
        private String likesCount;
        private List<String> comments;
        private String timeOfPost;
    }

    private static final ObjectMapper JACKSON = new ObjectMapper();
    public static void main(String[] args) throws IOException {
        MyObj o = JACKSON.readValue(args[0], MyObj.class); // assumes args[0] contains your json payload provided in your question.
    }
}

Let me know if you have any questions.

Apache Commons IO provides the FilenameUtils class which gives you a pretty rich set of utility functions for easily obtaining the various components of filenames, although The java.io.File class provides the basics.

This function is good for me:

public static int getDaysCount(Date begin, Date end) {

Here is my answer. To add ');' to the end of each line I do 'Find What: $' and 'Replace with: \);' you need to do escape;

I would suggest to load the .CSV file in MS-Access.

With MS-Excel you can then create a data connection to this source (without actual loading the records in a worksheet) and create a connected pivot table. You then can have virtually unlimited number of lines in your table (depending on processor and memory: I have now 15 mln lines with 3 Gb Memory).

Additional advantage is that you can now create an aggregate view in MS-Access. In this way you can create overviews from hundreds of millions of lines and then view them in MS-Excel (beware of the 2Gb limitation of NTFS files in 32 bits OS).

Radio buttons are meant to be required options... If you want them to be unchecked, use a checkbox, there is no need to complicate things and allow users to uncheck a radio button; removing the JQuery allows you to select from one of them

Just use a Reverse Proxy in your apache configuration (directly):

ProxyPass /foo http://foo.example.com/bar
ProxyPassReverse /foo http://foo.example.com/bar

Look here for apache documentation of how to use the mod

Follow these steps:

1. Open Netbeans
2. Click File > New Project > JavaFX > JavaFX with existing sources
3. Click Next
4. Name the project
5. Click Next
6. Under Source Package Folders click Add Folder
7. Select the nbproject folder under the zip file you wish to upload (Note: you need to unzip the folder)
8. Click Next
9. All the files will be included but you can exclude some if you wish
10. Click Finish and the project should be there

If you don't have the source folder added do the following

1. Under your projects directory tree right click on Source Packages
2. Click New
3. Click Java Package and name it with the name of the package the source files have
4. Go to the directory location (i.e., using Windows Explorer not Netbeans) of those source files, highlight them all, then drag and drop them under that Java Package you just created
5. Click Run
6. Click Clean and Build Project

Now you can have fun and run the application.

If all strings are std::string, you'll find strange problems with the cutoff of characters if using sizeof() because it's meant for C strings, not C++ strings. The fix is to use the .size() class method of std::string.

sHaystack.replace(sHaystack.find(sNeedle), sNeedle.size(), sReplace);

That replaces sHaystack inline -- no need to do an = assignment back on that.

Example usage:

std::string sHaystack = "This is %XXX% test.";
std::string sNeedle = "%XXX%";
std::string sReplace = "my special";
sHaystack.replace(sHaystack.find(sNeedle),sNeedle.size(),sReplace);
std::cout << sHaystack << std::endl;

Have you tried using the !important flag on the style? !important allows you to decide which style will win out. Also note !important will override inline styles as well.

#example p {
    color: blue !important;
}
...
#example p {
    color: red;
}

Another couple suggestions:

Add a span inside of the current. The inner most will win out. Although this could get pretty ugly.

<span class="style21">
<span style="position:absolute;top:432px;left:422px; color:Red" >relating to</span>
</span>

jQuery is also an option. The jQuery library will inject the style attribute in the targeted element.

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js" type="text/javascript" ></script>
    <script type="text/javascript">

        $(document).ready(function() {
            $("span").css("color", "#ff0000");
        });

    </script>

Hope this helps. CSS can be pretty frustrating at times.

add android:focusableInTouchMode="true" in root layout, when edit text will be clicked at that time cursor will be shown.

To avoid Float imperfections use Decimal

extension Float {
    func rounded(rule: NSDecimalNumber.RoundingMode, scale: Int) -> Float {
        var result: Decimal = 0
        var decimalSelf = NSNumber(value: self).decimalValue
        NSDecimalRound(&result, &decimalSelf, scale, rule)
        return (result as NSNumber).floatValue
    }
}

ex.
1075.58 rounds to 1075.57 when using Float with scale: 2 and .down
1075.58 rounds to 1075.58 when using Decimal with scale: 2 and .down

try this if you want your radio button to be checked based on value of some variable e.g. "genderStr" then you can use following code snippet

    if(genderStr.equals("Male"))
       genderRG.check(R.id.maleRB);
    else 
       genderRG.check(R.id.femaleRB);

Here is an example:

Process.Start("CMD", "/C Pause")


/C  Carries out the command specified by string and then terminates
/K  Carries out the command specified by string but remains

Note - This is not a solution to the original question. This is a solution to one of the subproblems discussed above.

Solution to @andr Clarification 2 -

Its really problematic when there's only one marker in the bounds and due to it the zoom level is set to a very high level (level 21). And Google does not provide any way to set the max zoom level at this point. This can also happen when there are more than 1 marker but they are all pretty close to each other. Then also the same problem will occur.

Solution - Suppose you want your Map to never go beyond 16 zoom level. Then after doing -

CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(bounds, padding);
mMap.moveCamera(cu);

Check if your zoom level has crossed level 16(or whatever you want) -

float currentZoom = mMap.getCameraPosition().zoom;

And if this level is greater than 16, which it will only be if there are very less markers or all the markers are very close to each other, then simply zoom out your map at that particular position only by seting the zoom level to 16.

mMap.moveCamera(CameraUpdateFactory.zoomTo(16));

This way you'll never have the problem of "bizarre" zoom level explained very well by @andr too.

You could use input type image.

<input type="image" src="http://example.com/path/to/image.png" />

It works as a button and can have the event handlers attached to it.

Alternatively, you can use css to style your button with a background image, and set the borders, margins and the like appropriately.

<button style="background: url(myimage.png)" ... />

In a single SQL query, without using the FOR XML clause.
A Common Table Expression is used to recursively concatenate the results.

-- rank locations by incrementing lexicographical order
WITH RankedLocations AS (
  SELECT
    VehicleID,
    City,
    ROW_NUMBER() OVER (
        PARTITION BY VehicleID

    ) Rank
  FROM
    Locations
),
-- concatenate locations using a recursive query
-- (Common Table Expression)
Concatenations AS (
  -- for each vehicle, select the first location
  SELECT
    VehicleID,
    CONVERT(nvarchar(MAX), City) Cities,
    Rank
  FROM
    RankedLocations
  WHERE
    Rank = 1

  -- then incrementally concatenate with the next location
  -- this will return intermediate concatenations that will be 
  -- filtered out later on
  UNION ALL

  SELECT
    c.VehicleID,
    (c.Cities + ', ' + l.City) Cities,
    l.Rank

    INNER JOIN RankedLocations l ON
        l.VehicleID = c.VehicleID 
        AND l.Rank = c.Rank + 1

Use jQuery to get the width of the window.

if ($(window).width() < 960) {
   alert('Less than 960');
}
else {
   alert('More than 960');
}

I also saw this change on my Mac when I went from running pip to sudo pip. Adding -H to sudo causes the message to go away for me. E.g.

sudo -H pip install foo

man sudo tells me that -H causes sudo to set $HOME to the target users (root in this case).

So it appears pip is looking into $HOME/Library/Log and sudo by default isn't setting $HOME to /root/. Not surprisingly ~/Library/Log is owned by you as a user rather than root.

I suspect this is some recent change in pip. I'll run it with sudo -H for now to work around.

1. df.iloc[0].head(1) - First data set only from entire first row.
2. df.iloc[0] - Entire First row in column.

You can't define an object literal with a dynamic key. Do this :

var o = {};
o[key] = value;
return o;

There's no shortcut (edit: there's one now, with ES6, see the other answer).

It also adds routing using controllers and views with KVO. You'll be able to develop "AJAXy" applications with it.

See it as a lightweight Sproutcore or Cappuccino framework.

I like this approach, it is visual for me.

using (var webClient = new WebClient())
    {
          var response = webClient.DownloadString(url);
          JObject result = JObject.Parse(response);
          var users = result.SelectToken("data");   
          List<User> userList = JsonConvert.DeserializeObject<List<User>>(users.ToString());
    }

Actually, for the configuration of the machine, just open the .vmx file with a text editor (e.g. notepad, gedit, etc.). You will be able to see the OS type, memsize, ethernet.connectionType, and other settings. Then when you make your machine, just look in the text editor for the corresponding settings. When it asks for the disk, select the .vmdk disk as mentioned above.

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

import matplotlib.pyplot as plt
%matplotlib inline
plt.rcParams["figure.figsize"] = [10, 5]

About this, java declares that on Windows 10, Edge browser does not support plugins, so it will NOT run java. (see https://www.java.com/it/download/win10.jsp --> only visible with edge in win10) It also reports a notice: java is not officially supported yet in Windows 10. (see https://www.java.com/it/download/faq/win10_faq.xml)

A default constructor is a constructor that either has no parameters, or if it has parameters, all the parameters have default values.

Use anchor links and the scroll-behavior property (MDN reference) for the scrolling container:

scroll-behavior: smooth;

Browser support: Firefox 36+, Chrome 61+ (therefore also Edge 79+) and Opera 48+.

Intenet Explorer, non-Chromium Edge and (so far) Safari do not support scroll-behavior and simply "jump" to the link target.

Example usage:

<head>
  <style type="text/css">
    html {
      scroll-behavior: smooth;
    }
  </style>
</head>
<body id="body">
  <a href="#foo">Go to foo!</a>

  <!-- Some content -->

  <div id="foo">That's foo.</div>
  <a href="#body">Back to top</a>
</body>

Here's a Fiddle.

And here's also a Fiddle with both horizontal and vertical scrolling.

You can combine PIL's Image.thumbnail with sys.maxsize if your resize limit is only on one dimension (width or height).

For instance, if you want to resize an image so that its height is no more than 100px, while keeping aspect ratio, you can do something like this:

import sys
from PIL import Image

image.thumbnail([sys.maxsize, 100], Image.ANTIALIAS)

Keep in mind that Image.thumbnail will resize the image in place, which is different from Image.resize that instead returns the resized image without changing the original one.

mvc:annotation-driven is a tag added in Spring 3.0 which does the following:

1. Configures the Spring 3 Type ConversionService (alternative to PropertyEditors)
2. Adds support for formatting Number fields with @NumberFormat
3. Adds support for formatting Date, Calendar, and Joda Time fields with @DateTimeFormat, if Joda Time is on the classpath
4. Adds support for validating @Controller inputs with @Valid, if a JSR-303 Provider is on the classpath
5. Adds support for support for reading and writing XML, if JAXB is on the classpath (HTTP message conversion with @RequestBody/@ResponseBody)
6. Adds support for reading and writing JSON, if Jackson is o n the classpath (along the same lines as #5)

context:annotation-config Looks for annotations on beans in the same application context it is defined and declares support for all the general annotations like @Autowired, @Resource, @Required, @PostConstruct etc etc.

Unfortunately all the answers in this post didn't work for me. I kept getting following error.

Failed to execute 'write' on 'Document': It isn't possible to write into a document from an asynchronously-loaded external script unless it is explicitly opened.

I found out that this happens if you use some 3rd party widgets (demandforce in my case) that also call additional external JavaScript files and try to insert HTML. Looking at the console and the JavaScript code, I noticed multiple lines like this:

document.write("<script type='text/javascript' "..."'></script>");

I used 3rd party JavaScript files (htmlParser.js and postscribe.js) from: https://github.com/krux/postscribe. That solved the problem in this post and fixed the above error at the same time.

(This was a quick and dirty way around under the tight deadline I have now. I am not comfortable with using 3rd party JavaScript library however. I hope someone can come up with a cleaner and better way.)

After a couple of hours of trying to solve the issue in several ways, some of which are described here, for me (on Win 10) the option of creating a Renviron file worked, but a little different from what was written here above. The task is to change the value of the variable R_LIBS_USER. To do this two steps needed:

1. Create the file named Renviron (without dot) in the folder \Program\etc\ (Programm is the directory where the R installed, for example for me it was c:\Program Files\R\R-4.0.0\etc)
2. Insert a line in Renviron with new path: R_LIBS_USER=c:/R/Library

It's been working for a few days already.

For example, I get date/time in format Spanish.

$('#timePicker').datetimepicker({
    defaultDate: new Date(),
    format:'DD/MM/YYYY HH:mm'
});

You can use strptime(3) to parse the time, and then mktime(3) to convert it to a time_t:

const char *time_details = "16:35:12";
struct tm tm;
strptime(time_details, "%H:%M:%S", &tm);
time_t t = mktime(&tm);  // t is now your desired time_t

If you are using Lodash library below is the way to set a dynamic variable in the angular scope.

To set the value in the angular scope.

_.set($scope, the_string, 'life.meaning')

To get the value from the angular scope.

_.get($scope, 'life.meaning')

Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.

First, click Slide Show > Set Up Show.

Put a checkmark to Loop continuously until 'Esc'.

Click Ok. Now, Click Slide Show > Custom Shows. Click New.

Select the slide you are looping, click Add. Click Ok and Close.

Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.

Right click on the thumbnail of the current slide, select Hide Slide.

Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"

This has worked for me.

sum(case when c.runstatus = 'Succeeded' then 1 else 0 end) as Succeeded, 
sum(case when c.runstatus = 'Failed' then 1 else 0 end) as Failed, 
sum(case when c.runstatus = 'Cancelled' then 1 else 0 end) as Cancelled, 

the issue here is that without the else statement, you are bound to receive a Null when the run status isn't the stated status in the column description. Adding anything to Null will result in Null, and that is the issue with this query.

Good Luck!

Try adding autostart="false" to your source tag.

<video width="640" height="480" controls="controls" type="video/mp4" preload="none">
<source src="http://example.com/mytestfile.mp4" autostart="false">
Your browser does not support the video tag.

JSFiddle example

Unexpected $end

When PHP talks about an "unexpected $end", it means that your code ended prematurely. (The message is a bit misleading when taken literally. It's not about a variable named "$end", as sometimes assumed by newcomers. It refers to the "end of file", EOF.)

Cause: Unbalanced { and } for code blocks / and function or class declarations.

It's pretty much always about a missing } curly brace to close preceding code blocks.

• Again, use proper indentation to avoid such issues.

• Use an IDE with bracket matching, to find out where the } is amiss. There are keyboard shortcuts in most IDEs and text editors:

  • NetBeans, PhpStorm, Komodo: Ctrl[ and Ctrl]
  • Eclipse, Aptana: CtrlShiftP
  • Atom, Sublime: Ctrlm - Zend Studio CtrlM
  • Geany, Notepad++: CtrlB - Joe: CtrlG - Emacs: C-M-n - Vim: %
    

Most IDEs also highlight matching braces, brackets and parentheses. Which makes it pretty easy to inspect their correlation:

Unterminated expressions

And Unexpected $end syntax/parser error can also occur for unterminated expressions or statements:

• $var = func(1, ?>EOF

So, look at the end of scripts first. A trailing ; is often redundant for the last statement in any PHP script. But you should have one. Precisely because it narrows such syntax issues down.

Indented HEREDOC markers

Another common occurrence appears with HEREDOC or NOWDOC strings. The terminating marker goes ignored with leading spaces, tabs, etc.:

print <<< END
    Content...
    Content....
  END;
# ? terminator isn't exactly at the line start

Therefore the parser assumes the HEREDOC string to continue until the end of the file (hence "Unexpected $end"). Pretty much all IDEs and syntax-highlighting editors will make this obvious or warn about it.

Escaped Quotation marks

If you use \ in a string, it has a special meaning. This is called an "Escape Character" and normally tells the parser to take the next character literally.

Example: echo 'Jim said \'Hello\''; will print Jim said 'hello'

If you escape the closing quote of a string, the closing quote will be taken literally and not as intended, i.e. as a printable quote as part of the string and not close the string. This will show as a parse error commonly after you open the next string or at the end of the script.

Very common error when specifiying paths in Windows: "C:\xampp\htdocs\" is wrong. You need "C:\\xampp\\htdocs\\".

Alternative syntax

Somewhat rarer you can see this syntax error when using the alternative syntax for statement/code blocks in templates. Using if: and else: and a missing endif; for example.

See also:

• PHP syntax error “unexpected $end”
• Parse error: Syntax error, unexpected end of file in my PHP code
• Parse error syntax error unexpected end of file, using PHP
• PHP Parse error: syntax error, unexpected end of file in a CodeIgniter View
• Parse error: syntax error, unexpected end of file (Registration script)
• "Parse error: syntax error, unexpected $end" For my uni registration assignment
• Fixing PHP Errors: PHP Error #3: Unexpected end of file

I prefer this way of handling this. You can check if the file exists synchronously:

var file = 'info.json';
var content = '';

// Check that the file exists locally
if(!fs.existsSync(file)) {
  console.log("File not found");
}

// The file *does* exist
else {
  // Read the file and do anything you want
  content = fs.readFileSync(file, 'utf-8');
}

Note: if your program also deletes files, this has a race condition as noted in the comments. If however you only write or overwrite files, without deleting them, then this is totally fine.

If you don't want to use a FormData object (e.g. your API takes specific content-type signatures and multipart/formdata isn't one of them) then you can do this instead:

uploadFile: function (event) {
    const file = event.target.files[0]
    axios.post('upload_file', file, {
        headers: {
          'Content-Type': file.type
        }
    })
}

You can use DecoratedBox.

@override
Widget build(BuildContext context) {
  return DecoratedBox(
    decoration: BoxDecoration(
      image: DecorationImage(image: AssetImage("your_asset"), fit: BoxFit.cover),
    ),
    child: Center(child: FlutterLogo(size: 300)),
  );
}

Output:

You should check Genson. It just works and is much easier to use than most of the existing alternatives in Scala. It is fast, has many features and integrations with some other libs (jodatime, json4s DOM api...).

All that without any fancy unecessary code like implicits, custom readers/writers for basic cases, ilisible API due to operator overload...

Using it is as easy as:

import com.owlike.genson.defaultGenson_

val json = toJson(Person(Some("foo"), 99))
val person = fromJson[Person]("""{"name": "foo", "age": 99}""")

case class Person(name: Option[String], age: Int)

Disclaimer: I am Gensons author, but that doesn't meen I am not objective :)

startInfo.Arguments = "/c \"netsh http add sslcert ipport=127.0.0.1:8085 certhash=0000000000003ed9cd0c315bbb6dc1c08da5e6 appid={00112233-4455-6677-8899-AABBCCDDEEFF} clientcertnegotiation=enable\"";

and...

startInfo.Arguments = "/c \"makecert -sk server -sky exchange -pe -n CN=localhost -ir LocalMachine -is Root -ic MyCA.cer -sr LocalMachine -ss My MyAdHocTestCert.cer\"";

The /c tells cmd to quit once the command has completed. Everything after /c is the command you want to run (within cmd), including all of the arguments.

Not sure about the performance implications, but it seems a possible compromise, at least during development, would be to include both the auto-incremented, integer "surrogate" key, as well as your intended, unique, "natural" key. This would give you the opportunity to evaluate performance, as well as other possible issues, including the changeability of natural keys.

Another way of doing this would be using Aggregation. You should be able to achieve a similar result using a single query. Such as this:

Item.objects.values("contest").annotate(Count("id"))

I did not test this specific query, but this should output a count of the items for each value in contests as a dictionary.

I have dealt WCF with large file (serveral GB) upload where store data in memory is not an option. My solution is to store message stream to a temp file and use seek to find out begin and end of binary data.

This is part of my code which makes spaces into underscores for naming my files:

$file = basename($_FILES['upload']['name']);
$file = str_replace(' ','_',$file);

From Web Application I think you can't, but you can rename all the folders in Git Client, it will move your files in the new renamed folders, than commit and push to remote repository.

I had a very similar issue: I had to rename different folders from uppercase to lowercase (like Abc -> abc), I've renamed all the folders with a dummy name (like 'abc___') and than committed to remote repository, after that I renamed all the folders to the original name with the lowercase (like abc) and it took them!

The main (very interesting) difference for me is that:
"string" & Null -> "string"
while
"string" + Null -> Null

But that's probably more useful in database apps like Access.

For Java 8 and higher:

    String[] test = {"1", "2", "3", "4", "5"};
    int[] ints = Arrays.stream(test).mapToInt(Integer::parseInt).toArray();

To add to what Evan said: C does not have a built-in operator for exponentiation, because it is not a primitive operation for most CPUs. Thus, it's implemented as a library function.

Also, for computing the function e^x, you can use the exp(double), expf(float), and expl(long double) functions.

Note that you do not want to use the ^ operator, which is the bitwise exclusive OR operator.

EDIT ouch, too late... I know read your comment stating that you want to keep the feature-x changeset around, so the cloning approach here doesn't work.

I'll still let the answer here for it may help others.

If you want to completely get rid of "feature X", because, for example, it didn't work, you can clone. This is one of the method explained in the article and it does work, and it talks specifically about heads.

As far as I understand you have this and want to get rid of the "feature-x" head once and for all:

@    changeset:   7:00a7f69c8335
|\   tag:         tip
| |  parent:      4:31b6f976956b
| |  parent:      2:0a834fa43688
| |  summary:     merge
| |
| | o  changeset:   5:013a3e954cfd
| |/   summary:     Closed branch feature-x
| |
| o  changeset:   4:31b6f976956b
| |  summary:     Changeset2
| |
| o  changeset:   3:5cb34be9e777
| |  parent:      1:1cc843e7f4b5
| |  summary:     Changeset 1
| |
o |  changeset:   2:0a834fa43688
|/   summary:     Changeset C

o  changeset:   1:1cc843e7f4b5
|  summary:     Changeset B
|
o  changeset:   0:a9afb25eaede
   summary:     Changeset A

So you do this:

hg clone . ../cleanedrepo --rev 7

And you'll have the following, and you'll see that feature-x is indeed gone:

@    changeset:   5:00a7f69c8335
|\   tag:         tip
| |  parent:      4:31b6f976956b

I may have misunderstood what you wanted but please don't mod down, I took time reproducing your use case : )

This is a very fast solution for one-dimensional atomic vectors. It relies on match(), so it is compatible with NA:

x <- c("a", NA, "a", "c", "a", "b", NA, "c")

fn <- function(x) {
  u <- unique.default(x)
  out <- list(x = u, freq = .Internal(tabulate(match(x, u), length(u))))
  class(out) <- "data.frame"
  attr(out, "row.names") <- seq_along(u)
  out
}

fn(x)

#>      x freq
#> 1    a    3
#> 2 <NA>    2
#> 3    c    2
#> 4    b    1

You could also tweak the algorithm so that it doesn't run unique().

fn2 <- function(x) {
  y <- match(x, x)
  out <- list(x = x, freq = .Internal(tabulate(y, length(x)))[y])
  class(out) <- "data.frame"
  attr(out, "row.names") <- seq_along(x)
  out
}

fn2(x)

#>      x freq
#> 1    a    3
#> 2 <NA>    2
#> 3    a    3
#> 4    c    2
#> 5    a    3
#> 6    b    1
#> 7 <NA>    2
#> 8    c    2

In cases where that output is desirable, you probably don't even need it to re-return the original vector, and the second column is probably all you need. You can get that in one line with the pipe:

match(x, x) %>% `[`(tabulate(.), .)

#> [1] 3 2 3 2 3 1 2 2

There are three ways to fetch multiple rows returned by PDO statement.

The simplest one is just to iterate over PDOStatement itself:

$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// iterating over a statement
foreach($stmt as $row) {
    echo $row['name'];
}

another one is to fetch rows using fetch() method inside a familiar while statement:

$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// using while
while($row = $stmt->fetch()) {
    echo $row['name'];
}

but for the modern web application we should have our datbase iteractions separated from output and thus the most convenient method would be to fetch all rows at once using fetchAll() method:

$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// fetching rows into array
$data = $stmt->fetchAll();

or, if you need to preprocess some data first, use the while loop and collect the data into array manually

$result = [];
$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// using while
while($row = $stmt->fetch()) {
    $result[] = [
        'newname' => $row['oldname'],
        // etc
    ];
}

and then output them in a template:

<ul>
<?php foreach($data as $row): ?>
    <li><?=$row['name']?></li>
<?php endforeach ?>
</ul>

Note that PDO supports many sophisticated fetch modes, allowing fetchAll() to return data in many different formats.

Just try this:

<button type="button">Click Me</button>
<p></p>
<script type="text/javascript">
    $(document).ready(function(){
        $("button").click(function(){

            $.ajax({
                type: 'POST',
                url: 'script.php',
                success: function(data) {
                    alert(data);
                    $("p").text(data);

                }
            });
   });
});
</script>

In script.php

<?php 
  echo "You win";
 ?>

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

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

Very simply

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

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

There's 3 satellites at least that you must be able to receive from of the 24-32 out there, and they each broadcast a time from a synchronized atomic clock. The differences in those times that you receive at any one time tell you how long the broadcast took to reach you, and thus where you are in relation to the satellites. So, it sort of reads from something, but it doesn't connect to that thing. Note that this doesn't tell you your orientation, many GPSes fake that (and speed) by interpolating data points.

If you don't count the cost of the receiver, it's a free service. Apparently there's higher resolution services out there that are restricted to military use. Those are likely a fixed cost for a license to decrypt the signals along with a confidentiality agreement.

Now your device may support GPS tracking, in which case it might communicate, say via GPRS, to a database which will store the location the device has found itself to be at, so that multiple devices may be tracked. That would require some kind of connection.

Maps are either stored on the device or received over a connection. Navigation is computed based on those maps' databases. These likely are a licensed item with a cost associated, though if you use a service like Google Maps they have the license with NAVTEQ and others.

I came around the same problem as the OP, and trying some solutions from the top answers above didn't prove to work for my scenarios. See why at the end.

Instead, I found this helpful script, to avoid confusion let's call it html2text_roundcube, available under GPL:

• https://github.com/mtibben/html2text

It's actually an updated version of an already mentioned script - http://www.chuggnutt.com/html2text.php - updated by RoundCube mail.

Usage:

$h2t = new \Html2Text\Html2Text('Hello, &quot;<b>world</b>&quot;');
echo $h2t->getText(); // prints Hello, "WORLD"

Why html2text_roundcube proved better than the others:

• Script http://www.chuggnutt.com/html2text.php didn't work out of the box for cases with special HTML codes/names (eg ä), or unpaired quotes (eg <p>25" Monitor</p>).

• Script https://github.com/soundasleep/html2text had no option to hide or group the links at the end of the text, making a usual HTML page look bloated with links when in text-plain format; customizing the code for special treatment of how the transformation is done is not as straight forward as simply editing an array in html2text_roundcube.

It is all about preventing definitions from clashing with other code linked in to your project. It means you can keep things separate.

For example you can have one method called "run" in your code and you will still be able to call your method rather than the "run" method that has been defined in some other library that you have linked in.

Since you've got both the shell that you're typing into and the shell that sudo -s runs, you need to quote or escape twice. (EDITED fixed quoting)

sudo -su db2inst1 '/opt/ibm/db2/V9.7/bin/db2 force application \(1995\)'

or

sudo -su db2inst1 /opt/ibm/db2/V9.7/bin/db2 force application \\\(1995\\\)

Out of curiosity, why do you need -s? Can't you just do this:

sudo -u db2inst1 /opt/ibm/db2/V9.7/bin/db2 force application \(1995\)

The child views in your list row should be considered selected whenever the parent row is selected, so you should be able to just set a normal state drawable/color-list on the views you want to change, no messy Java code necessary. See this SO post.

Specifically, you'd set the textColor of your textViews to an XML resource like this one:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:drawable="@color/black" /> <!-- focused -->
    <item android:state_focused="true" android:state_pressed="true" android:drawable="@color/black" /> <!-- focused and pressed-->
    <item android:state_pressed="true" android:drawable="@color/green" /> <!-- pressed -->
    <item android:drawable="@color/black" /> <!-- default -->
</selector> 

grid is not a global, it is local to the main function. Change this:

int nonrecursivecountcells(color[ROW_SIZE][COL_SIZE], int row, int column)

to this:

int nonrecursivecountcells(color grid[ROW_SIZE][COL_SIZE], int row, int column)

Basically you forgot to give that first param a name, grid will do since it matches your code.

Exported variables such as $HOME and $PATH are available to (inherited by) other programs run by the shell that exports them (and the programs run by those other programs, and so on) as environment variables. Regular (non-exported) variables are not available to other programs.

$ env | grep '^variable='
$                                 # No environment variable called variable
$ variable=Hello                  # Create local (non-exported) variable with value
$ env | grep '^variable='
$                                 # Still no environment variable called variable
$ export variable                 # Mark variable for export to child processes
$ env | grep '^variable='
variable=Hello
$
$ export other_variable=Goodbye   # create and initialize exported variable
$ env | grep '^other_variable='
other_variable=Goodbye
$

For more information, see the entry for the export builtin in the GNU Bash manual, and also the sections on command execution environment and environment.

Note that non-exported variables will be available to subshells run via ( ... ) and similar notations because those subshells are direct clones of the main shell:

$ othervar=present
$ (echo $othervar; echo $variable; variable=elephant; echo $variable)
present
Hello
elephant
$ echo $variable
Hello
$

The subshell can change its own copy of any variable, exported or not, and may affect the values seen by the processes it runs, but the subshell's changes cannot affect the variable in the parent shell, of course.

Some information about subshells can be found under command grouping and command execution environment in the Bash manual.

The easier way to only change the radio button is simply set selector for drawable right

<RadioButton
    ...
    android:button="@null"
    android:checked="false"
    android:drawableRight="@drawable/radio_button_selector" />

And the selector is:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ic_checkbox_checked" android:state_checked="true" />
    <item android:drawable="@drawable/ic_checkbox_unchecked" android:state_checked="false" /></selector>

That's all

The Spring Framework has a class which allows to recursively search through the classpath:

PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
resolver.getResources("classpath*:some/package/name/**/*.xml");
