You should include the repository where you want to deploy in the distribution management section of the pom.xml.

Example:

<project xmlns="http://maven.apache.org/POM/4.0.0"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
                      http://maven.apache.org/xsd/maven-4.0.0.xsd">
...   
<distributionManagement>
    <repository>
      <uniqueVersion>false</uniqueVersion>
      <id>corp1</id>
      <name>Corporate Repository</name>
      <url>scp://repo/maven2</url>
      <layout>default</layout>
    </repository>
    ...
</distributionManagement>
...
</project>

If you were like me, running maven compile deploy from eclipse's maven run configuration, the issue could be related to eclipse's own embedded maven as described in https://bugs.eclipse.org/bugs/show_bug.cgi?id=562847

The workaround is to run mvn compile deploy from CLI such as bash, or to NOT use embedded maven in the eclipse's maven run configuration, and add an external maven (mine is in /usr/share/mvn), and voila, it'll say BUILD SUCCESS.

1. Check the plugins which cannot be found (maven-site-plugin,maven-resources-plugin)
2. go to '.m2/repository/org/apache/maven/plugins/'
3. delete the directory rm -rf plugin-directory-name (eg: rm -rf maven-site-plugin)
4. exit project from intellij
5. import project again
6. Do a Maven reimport

Explanation: when you do a maven reimport, it will download all the missing plugins again.

Happy Coding

You can also override the deployment repository on the command line: -Darguments=-DaltDeploymentRepository=myreposid::default::http://my/url/releases

To get the boolean value for the hit on the ip

public Boolean getInetAddressByName(String name)
    {
        AsyncTask<String, Void, Boolean> task = new AsyncTask<String, Void, Boolean>()
        {

            @Override
            protected Boolean doInBackground(String... params) {
                try
                {
                    return InetAddress.getByName(params[0]).isReachable(2000);
                }
                catch (Exception e)
                {
                    return null;
                }
            }
        };
        try {
            return task.execute(name).get();
        }
        catch (InterruptedException e) {
            return null;
        }
        catch (ExecutionException e) {
            return null;
        }

    }

Try this

table tr td.classname
{
 text-align:right;
 padding-right:18%;
}

Here is how one can do it. I will give an example with joining so that it becomes super clear to someone.

$products = DB::table('products AS pr')
        ->leftJoin('product_families AS pf', 'pf.id', '=', 'pr.product_family_id')
        ->select('pr.id as id', 'pf.name as product_family_name', 'pf.id as product_family_id')
        ->orderBy('pr.id', 'desc')
        ->get();

Hope this helps.

You can use (hidden) cells as variables. E.g., you could hide Column C, set C1 to

=20

and use it as

=c1*20

Alternatively you can write VBA Macros which set and read a global variable.

Edit: AKX renders my Answer partially incorrect. I had no idea you could name cells in Excel.

Yeah it's possible.

Button myBtn = (Button)findViewById(R.id.myButtonId);
myBtn.requestFocus();

or in XML

<Button ...><requestFocus /></Button>

Important Note: The button widget needs to be focusable and focusableInTouchMode. Most widgets are focusable but not focusableInTouchMode by default. So make sure to either set it in code

myBtn.setFocusableInTouchMode(true);

or in XML

android:focusableInTouchMode="true"

Yes it is, and you can also use it like this

<button>Click here to<br/> start playing</button>

if you want to make the break yourself.

This is just a sample code, but it may help you get on your way:

Public Sub testIt()
    Workbooks("Workbook2").Activate
    ActiveWorkbook.Sheets("Sheet2").Activate
    ActiveSheet.Range("B3").Select
    ActiveCell.EntireRow.Insert
End Sub

I am assuming that you can open the book (called Workbook2 in the example).

I think (but I'm not sure) you can squash all this in a single line of code:

    Workbooks("Workbook2").Sheets("Sheet2").Range("B3").EntireRow.Insert

This way you won't need to activate the workbook (or sheet or cell)... Obviously, the book has to be open.

The exact wording of the latest published standard (C++14) is:

An implementation shall allow both

• a function of () returning int and

• a function of (int, pointer to pointer to char) returning int

as the type of main.

This makes it clear that alternative spellings are permitted so long as the type of main is the type int() or int(int, char**). So the following are also permitted:

• int main(void)
• auto main() -> int
• int main ( )
• signed int main()
• typedef char **a; typedef int b, e; e main(b d, a c)

I'm a devops engineer and this happens with private repositories. Since I manage multiple Github organizations, I have a few different SSH keys. To overcome this ERROR: Repository not found. fatal: Could not read from remote repository. error, you can use

export GIT_SSH_COMMAND="ssh -o StrictHostKeyChecking=no -o User=git -i ~/.ssh/ssh_key_for_repo"

git clone [email protected]:user/repo.git

Tejas Lagvankar wrote a nice post about this subject. Below are some key differences between Service and IntentService.

When to use?

• The Service can be used in tasks with no UI, but shouldn't be too long. If you need to perform long tasks, you must use threads within Service.

• The IntentService can be used in long tasks usually with no communication to Main Thread. If communication is required, can use Main Thread handler or broadcast intents. Another case of use is when callbacks are needed (Intent triggered tasks).

How to trigger?

• The Service is triggered by calling method startService().

• The IntentService is triggered using an Intent, it spawns a new worker thread and the method onHandleIntent() is called on this thread.

Triggered From

• The Service and IntentService may be triggered from any thread, activity or other application component.

Runs On

• The Service runs in background but it runs on the Main Thread of the application.

• The IntentService runs on a separate worker thread.

Limitations / Drawbacks

• The Service may block the Main Thread of the application.

• The IntentService cannot run tasks in parallel. Hence all the consecutive intents will go into the message queue for the worker thread and will execute sequentially.

When to stop?

• If you implement a Service, it is your responsibility to stop the service when its work is done, by calling stopSelf() or stopService(). (If you only want to provide binding, you don't need to implement this method).

• The IntentService stops the service after all start requests have been handled, so you never have to call stopSelf().

It is unfortunately not supported in older versions of MSTest. Apparently there is an extensibility model and you can implement it yourself. Another option would be to use data-driven tests.

My personal opinion would be to just stick with NUnit though...

As of Visual Studio 2012, update 1, MSTest has a similar feature. See McAden's answer.

On centOS7 I changed the file /etc/httpd/conf/httpd.conf

from AllowOverride None to AllowOverride All

Okay so here's the solution. Most everyone made really good points but none solved the problem (THANKS for the help). Here is the solution I found to work.

1. Move jars from .../web-inf/lib to PROJECT_ROOT/lib
2. Alter build path in eclipse to reflect this change.
3. cleaned and rebuilt my project.
4. ran the junit test and BOOM it worked!

My guess is that it had something to do with how Ganymede reads jars in the /web-inf/lib folder. But who knows... It works now.

    <script type="application/javascript">
            function getip(json){
            alert(json.ip); // alerts the ip address
    }
    </script>

    <script type="application/javascript" src="http://jsonip.appspot.com/?callback=getip"></script>

If you already test with a submit action, you have noticed that not works too.

The reason is the form is alread posted in a $(document).read(...

So, all you need to do is change that to $(document).load(...

Now, in the moment of you browaser load the page, he will execute.

And will work ;D

you can do these line on your mysql query browser or something

SET old_passwords = 0;
UPDATE mysql.user SET Password = PASSWORD('testpass') WHERE User = 'testuser' limit 1;
SELECT LENGTH(Password) FROM mysql.user WHERE User = 'testuser';
FLUSH PRIVILEGES;

note:your username and password

after that it should able to work. I just solved mine too

You don't need to create a button. The facility exists by default.

Just right click on the arrow buttons on the bottom left hand corner of the Excel window. These are the arrow buttons which if you left click move left or right one worksheet.

If you right-click on these arrows Excel will pop up a dialogue with a list of worksheets from which you can click to set your chosen sheet active.

You can achieve this by using few lines of code. So why you are going to stuck in third party library or UI. Pull to refresh is built in iOS. You could do this in swift like

var pullControl = UIRefreshControl()

override func viewDidLoad() {
   super.viewDidLoad()

   pullControl.attributedTitle = NSAttributedString(string: "Pull to refresh")
   pullControl.addTarget(self, action: #selector(pulledRefreshControl(_:)), for: UIControl.Event.valueChanged)
   tableView.addSubview(pullControl) // not required when using UITableViewController
}

@objc func pulledRefreshControl(sender:AnyObject) {
   // Code to refresh table view  
}

java.time

Since Java 1.8, you can achieve this without an extra library by using the java.time classes. See Tutorial.

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MMM-dd");
formatter = formatter.withLocale( putAppropriateLocaleHere );  // Locale specifies human language for translating, and cultural norms for lowercase/uppercase and abbreviations and such. Example: Locale.US or Locale.CANADA_FRENCH
LocalDate date = LocalDate.parse("2005-nov-12", formatter);

The syntax is nearly the same though.

Include <%@ page isELIgnored="false"%> on top of your jsp page.

I had to include "PROJECT_NAME/osdep.h" and that includes the os specific configurations.

I would look in other files using the types you are interested in and find where/how they are defined (by looking at includes).

This script is ok except for this case that of course, I've met :

INSERT INTO "requestcomparison_stopword" VALUES(149,'f');
INSERT INTO "requestcomparison_stopword" VALUES(420,'t');

The script should give this output :

INSERT INTO requestcomparison_stopword VALUES(149,'f');
INSERT INTO requestcomparison_stopword VALUES(420,'t');

But gives instead that output :

INSERT INTO requestcomparison_stopword VALUES(1490;
INSERT INTO requestcomparison_stopword VALUES(4201;

with some strange non-ascii characters around the last 0 and 1.

This didn't show up anymore when I commented the following lines of the code (43-46) but others problems appeared:

    line = re.sub(r"([^'])'t'(.)", "\1THIS_IS_TRUE\2", line)
    line = line.replace('THIS_IS_TRUE', '1')
    line = re.sub(r"([^'])'f'(.)", "\1THIS_IS_FALSE\2", line)
    line = line.replace('THIS_IS_FALSE', '0')

This is just a special case, when we want to add a value being 'f' or 't' but I'm not really comfortable with regular expressions, I just wanted to spot this case to be corrected by someone.

Anyway thanks a lot for that handy script !!!

If you want to retrieve multiple values of attributes from the source above, you can use findAll and a list comprehension to get everything you need:

import urllib
f = urllib.urlopen("http://58.68.130.147")
s = f.read()
f.close()

from BeautifulSoup import BeautifulStoneSoup
soup = BeautifulStoneSoup(s)

inputTags = soup.findAll(attrs={"name" : "stainfo"})
### You may be able to do findAll("input", attrs={"name" : "stainfo"})

output = [x["stainfo"] for x in inputTags]

print output
### This will print a list of the values.

If you want to visualize your dependencies in a graph you can use gradle-dependency-graph-generator plugin.

Generally the output of this plugin can be found in build/reports/dependency-graph directory and it contains three files (.dot|.png|.svg) if you are using the 0.5.0 version of the plugin.

Example of dependences graph in a real app (Chess Clock):

As far as I know there is no “native” PowerShell way of getting this information. And perhaps it is rather the .NET limitation than PowerShell.

Here is the suggestion to add this functionality to the version next:

https://connect.microsoft.com/PowerShell/feedback/details/424948/i-would-like-to-see-the-property-starttype-added-to-get-services

The WMI workaround is also there, just in case. I use this WMI solution for my tasks and it works.

Do you have to use a HashMap? If you only need the Map Interface use a TreeMap

If you want to sort by comparing values in the HashMap. You have to write code to do this, if you want to do it once you can sort the values of your HashMap:

Map<String, Person> people = new HashMap<>();
Person jim = new Person("Jim", 25);
Person scott = new Person("Scott", 28);
Person anna = new Person("Anna", 23);

people.put(jim.getName(), jim);
people.put(scott.getName(), scott);
people.put(anna.getName(), anna);

// not yet sorted
List<Person> peopleByAge = new ArrayList<>(people.values());

Collections.sort(peopleByAge, Comparator.comparing(Person::getAge));

for (Person p : peopleByAge) {
    System.out.println(p.getName() + "\t" + p.getAge());
}

If you want to access this sorted list often, then you could insert your elements into a HashMap<TreeSet<Person>>, though the semantics of sets and lists are a bit different.

Now to answer the question that perhaps you should have asked, like "I'm getting 100 floats form somewhere; do I need to put them in an array or list before I find the minimum?"

Answer: No, if somewhere is a iterable, instead of doing this:

temp = []
for x in somewhere:
   temp.append(x)
answer = min(temp)

you can do this:

answer = min(somewhere)

Example:

answer = min(float(line) for line in open('floats.txt'))

In my case, I knew the child component would always be present, but wanted to alter the state prior to the child initializing to save work.

I choose to test for the child until it appeared and make changes immediately, which saved me a change cycle on the child component.

export class GroupResultsReportComponent implements OnInit {

    @ViewChild(ChildComponent) childComp: ChildComponent;

    ngOnInit(): void {
        this.WhenReady(() => this.childComp, () => { this.childComp.showBar = true; });
    }

    /**
     * Executes the work, once the test returns truthy
     * @param test a function that will return truthy once the work function is able to execute 
     * @param work a function that will execute after the test function returns truthy
     */
    private WhenReady(test: Function, work: Function) {
        if (test()) work();
        else setTimeout(this.WhenReady.bind(window, test, work));
    }
}

Alertnatively, you could add a max number of attempts or add a few ms delay to the setTimeout. setTimeout effectively throws the function to the bottom of the list of pending operations.

I am not convinced that you'll need an external sorting program in Bash.

Here is my implementation for the simple bubble-sort algorithm.

function bubble_sort()
{   #
    # Sorts all positional arguments and echoes them back.
    #
    # Bubble sorting lets the heaviest (longest) element sink to the bottom.
    #
    local array=($@) max=$(($# - 1))
    while ((max > 0))
    do
        local i=0
        while ((i < max))
        do
            if [ ${array[$i]} \> ${array[$((i + 1))]} ]
            then
                local t=${array[$i]}
                array[$i]=${array[$((i + 1))]}
                array[$((i + 1))]=$t
            fi
            ((i += 1))
        done
        ((max -= 1))
    done
    echo ${array[@]}
}

array=(a c b f 3 5)
echo " input: ${array[@]}"
echo "output: $(bubble_sort ${array[@]})"

This shall print:

 input: a c b f 3 5
output: 3 5 a b c f

Perhaps use plt.annotate:

import numpy as np
import matplotlib.pyplot as plt

N = 10
data = np.random.random((N, 4))
labels = ['point{0}'.format(i) for i in range(N)]

plt.subplots_adjust(bottom = 0.1)
plt.scatter(
    data[:, 0], data[:, 1], marker='o', c=data[:, 2], s=data[:, 3] * 1500,
    cmap=plt.get_cmap('Spectral'))

for label, x, y in zip(labels, data[:, 0], data[:, 1]):
    plt.annotate(
        label,
        xy=(x, y), xytext=(-20, 20),
        textcoords='offset points', ha='right', va='bottom',
        bbox=dict(boxstyle='round,pad=0.5', fc='yellow', alpha=0.5),
        arrowprops=dict(arrowstyle = '->', connectionstyle='arc3,rad=0'))

plt.show()

I would suggest the use of jquery mate.

With jQuery you would then be able to get the id of this element by

$(this).attr('id');

without jquery, if I remember correctly we used to access the id with a

this.id

Hope that helps :)

On Windows7 the .gemrc file is not present, you can let Ruby create one like this (it's not easy to do this in explorer).

gem sources --add http://rubygems.org

You will have to confirm (it's unsafe). Now the file is created in your userprofile folder (c:\users\)

You can edit the textfile to remove the source you added or you can remove it with

gem sources --remove http://rubygems.org

here whatever we write in between the pre tags it will be interpreted same as html pre tag

ex:

<?php
echo '<pre>';
echo '
code here 
will be displayed
as it 
is 


namaste
';
echo "this line get printed in new line";
echo "</pre>";
echo "Now pre ended:";
echo "this line gets joined to above line";
?>

and content b/w 's font also changes.

Date().toLocaleString() returns this: 7/31/2018, 12:58:03 PM

Pretty close - just drop the comma and the seconds:

new Date().toLocaleString().replace(",","").replace(/:.. /," ");

Results: 7/31/2018 12:58 PM

Like Rubanov wrote for C#, i write it for Java, and it is:

    public void waitForPageLoaded() {
    ExpectedCondition<Boolean> expectation = new
            ExpectedCondition<Boolean>() {
                public Boolean apply(WebDriver driver) {
                    return (((JavascriptExecutor) driver).executeScript("return document.readyState").toString().equals("complete")&&((Boolean)((JavascriptExecutor)driver).executeScript("return jQuery.active == 0")));
                }
            };
    try {
        Thread.sleep(100);
        WebDriverWait waitForLoad = new WebDriverWait(driver, 30);
        waitForLoad.until(expectation);
    } catch (Throwable error) {
        Assert.fail("Timeout waiting for Page Load Request to complete.");
    }
}

To soluction it you should configure a xml binding before to compile with wsimport, setting generateElementProperty as false.

     <jaxws:bindings wsdlLocation="LOCATION_OF_WSDL"

Connect didn't work for me, The problem was that Genymotion uses its own dk-tools and you need to change it to custom SDK tools.

You can do something like the following these days by referencing the "beforeSubmit" jquery form event. I'm disabling and enabling the submit button to avoid duplicate requests, submitting via ajax, returning a message that's a json array and displaying the information in a pNotify:

jQuery('body').on('beforeSubmit', "#formID", function() {
    $('.submitter').prop('disabled', true);
    var form = $('#formID');
    $.ajax({
        url    : form.attr('action'),
        type   : 'post',
        data   : form.serialize(),
        success: function (response)
        {
            response = jQuery.parseJSON(response);
            new PNotify({
                text: response.message,
                type: response.status,
                styling: 'bootstrap3',
                delay: 2000,
            });
            $('.submitter').prop('disabled', false);
        },
        error  : function ()
        {
            console.log('internal server error');
        }
    });
});

In case of huge tables standard way with sorting by dbms_random.value is not effective because you need to scan whole table and dbms_random.value is pretty slow function and requires context switches. For such cases, there are 3 additional methods:

1: Use sample clause:

• https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/SELECT.html#GUID-CFA006CA-6FF1-4972-821E-6996142A51C6
• https://docs.oracle.com/en/database/oracle/oracle-database/19/sqlrf/SELECT.html#GUID-CFA006CA-6FF1-4972-821E-6996142A51C6

for example:

select *
from s1 sample block(1)
order by dbms_random.value
fetch first 1 rows only

ie get 1% of all blocks, then sort them randomly and return just 1 row.

2: if you have an index/primary key on the column with normal distribution, you can get min and max values, get random value in this range and get first row with a value greater or equal than that randomly generated value.

Example:

--big table with 1 mln rows with primary key on ID with normal distribution:
Create table s1(id primary key,padding) as 
   select level, rpad('x',100,'x')
   from dual 
   connect by level<=1e6;

select *
from s1 
where id>=(select 
              dbms_random.value(
                 (select min(id) from s1),
                 (select max(id) from s1) 
              )
           from dual)
order by id
fetch first 1 rows only;

3: get random table block, generate rowid and get row from the table by this rowid:

select * 
from s1
where rowid = (
   select
      DBMS_ROWID.ROWID_CREATE (
         1, 
         objd,
         file#,
         block#,
         1) 
   from    
      (
      select/*+ rule */ file#,block#,objd
      from v$bh b
      where b.objd in (select o.data_object_id from user_objects o where object_name='S1' /* table_name */)
      order by dbms_random.value
      fetch first 1 rows only
      )
);

In case of using psr-0 , check the class name does not contain underscore .

I'm not sure if this is the most pythonic method ... I had a list of tuples that needed sorting 1st by descending integer values and 2nd alphabetically. This required reversing the integer sort but not the alphabetical sort. Here was my solution: (on the fly in an exam btw, I was not even aware you could 'nest' sorted functions)

a = [('Al', 2),('Bill', 1),('Carol', 2), ('Abel', 3), ('Zeke', 2), ('Chris', 1)]  
b = sorted(sorted(a, key = lambda x : x[0]), key = lambda x : x[1], reverse = True)  
print(b)  
[('Abel', 3), ('Al', 2), ('Carol', 2), ('Zeke', 2), ('Bill', 1), ('Chris', 1)]

If you're finding by Contains then it'll be like this

    $("input[id*='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you're finding by Starts With then it'll be like this

    $("input[id^='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you're finding by Ends With then it'll be like this

     $("input[id$='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you want to select elements which id is not a given string

    $("input[id!='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you want to select elements which name contains a given word, delimited by spaces

     $("input[name~='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you want to select elements which id is equal to a given string or starting with that string followed by a hyphen

     $("input[id|='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

A complete function of the most voted answer:

function remote_file_exists($url)
{
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_NOBODY, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); # handles 301/2 redirects
    curl_exec($ch);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);
    if( $httpCode == 200 ){return true;}
}

You can use it like this:

if(remote_file_exists($url))
{
    //file exists, do something
}

echo $TESTSTRINGONE|awk '{print substr($0,0,5)}'

Another option is to use mongoose-history plugin.

let mongoose = require('mongoose');
let mongooseHistory = require('mongoose-history');
let Schema = mongoose.Schema;

let MySchema = Post = new Schema({
    title: String,
    status: Boolean
});

MySchema.plugin(mongooseHistory);
// The plugin will automatically create a new collection with the schema name + "_history".
// In this case, collection with name "my_schema_history" will be created.

Remember that HTML and XML are two distinct concepts in the tree of markup languages. You can't exactly replace HTML with XML . XML can be viewed as a generalized form of HTML, but even that is imprecise. You mainly use HTML to display data, and XML to carry(or store) the data.

This link is helpful: How to read HTML as XML?

Just to clearify, in /etc/nginx/nginx.conf, you can put at the beginning of the file the line

error_log /var/log/nginx/error.log debug;

And then restart nginx:

sudo service nginx restart

That way you can detail what nginx is doing and why it is returning the status code 400.

Also, you do not have to use nested CASEs. You can use several WHEN-THEN lines and the ELSE line is also optional eventhough I recomend it

CASE 
   WHEN [condition.1] THEN [expression.1]
   WHEN [condition.2] THEN [expression.2]
   ...
   WHEN [condition.n] THEN [expression.n]
   ELSE [expression] 
END

If you don't mind using 3rd party libraries, AOL's cyclops-react lib, disclosure::I am a contributor, has a ExceptionSoftener class that can help here.

 s.filter(softenPredicate(a->a.isActive()));

Few lines solution without redundant pairs of variables:

corr_matrix = df.corr().abs()

#the matrix is symmetric so we need to extract upper triangle matrix without diagonal (k = 1)

sol = (corr_matrix.where(np.triu(np.ones(corr_matrix.shape), k=1).astype(np.bool))
                  .stack()
                  .sort_values(ascending=False))

#first element of sol series is the pair with the biggest correlation

Then you can iterate through names of variables pairs (which are pandas.Series multi-indexes) and theirs values like this:

for index, value in sol.items():
  # do some staff

You can try export http_proxy=http://your_proxy:your_port

Static Typing: The languages such as Java and Scala are static typed.

The variables have to be defined and initialized before they are used in a code.

for ex. int x; x = 10;

System.out.println(x);

Dynamic Typing: Perl is an dynamic typed language.

Variables need not be initialized before they are used in code.

y=10; use this variable in the later part of code

text function set or retrieve the value as plain text, otherwise, HTML function set or retrieve the value as HTML tags to change or modify that. If you want to just change the content then use text(). But if you need to change the markup then you have to use hmtl().

It's a dummy answer for me after six years, Don't mind.

This works:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Me.Hide()

You can use ethtool:

$ sudo ethtool eth0
Settings for eth0:

To only get the Link status you can use grep:

$ sudo ethtool eth0 | grep Link

This should work:

User.Identity.Name

Identity returns an IPrincipal

Here is the link to the Microsoft documentation.

To achieve this in WPF I do it the following way.

 new Thread(() => 
 {
     while (...)
     {
         SomeLabel.Dispatcher.BeginInvoke((Action)(() => SomeLabel.Text = ...));
     }
 }).Start();

In Win 7, navigate to the directory where your text files are. On the command prompt use:

copy *.txt combined.txt

Where combined.txt is the name of the newly created text file.

Use the zip and iter commands together:

I find this solution using iter to be quite elegant:

it = iter(l)
list(zip(it, it))
# [(1, 2), (3, 4), (5, 6)]

Which I found in the Python 3 zip documentation.

it = iter(l)
print(*(f'{u} + {v} = {u+v}' for u, v in zip(it, it)), sep='\n')

# 1 + 2 = 3
# 3 + 4 = 7
# 5 + 6 = 11

To generalise to N elements at a time:

N = 2
list(zip(*([iter(l)] * N)))
# [(1, 2), (3, 4), (5, 6)]

There are a couple of things that you need to check related to this.

Whenever there is an error like this thrown related to making a secure connection, try running a script like the one below in Powershell with the name of the machine or the uri (like "www.google.com") to get results back for each of the different protocol types:

 function Test-SocketSslProtocols {
    
    [CmdletBinding()]

        [Parameter(Mandatory=$true)][string]$ComputerName,
        [int]$Port = 443,

        )

    #set results list    
    $ProtocolStatusObjArr = [System.Collections.ArrayList]@()


    if($ProtocolNames -eq $null){

        #if parameter $ProtocolNames empty get system list
        $ProtocolNames = [System.Security.Authentication.SslProtocols] | Get-Member -Static -MemberType Property | Where-Object { $_.Name -notin @("Default", "None") } | ForEach-Object { $_.Name }

    }
 
    foreach($ProtocolName in $ProtocolNames){

Test-SocketSslProtocols -ComputerName "www.google.com"

It will try to establish socket connections and return complete objects for each attempt and successful connection.

After seeing what returns, check your computer registry via regedit (put "regedit" in run or look up "Registry Editor"), place

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL

in the filepath and ensure that you have the appropriate TLS Protocol enabled for whatever server you're trying to connect to (from the results you had returned from the scripts). Adjust as necessary and then reset your computer (this is required). Try connecting with the powershell script again and see what results you get back. If still unsuccessful, ensure that the algorithms, hashes, and ciphers that need to be enabled are narrowing down what needs to be enabled (IISCrypto is a good application for this and is available for free. It will give you a real time view of what is enabled or disabled in your SChannel registry where all these things are located).

Also keep in mind the Windows version, DotNet version, and updates you have currently installed because despite a lot of TLS options being enabled by default in Windows 10, previous versions required patches to enable the option.

One last thing: TLS is a TWO-WAY street (keep this in mind) with the idea being that the server's having things available is just as important as the client. If the server only offers to connect via TLS 1.2 using certain algorithms then no client will be able to connect with anything else. Also, if the client won't connect with anything else other than a certain protocol or ciphersuite the connection won't work. Browsers are also something that need to be taken into account with this because of their forcing errors on HTTP2 for anything done with less than TLS 1.2 DESPITE there NOT actually being an error (they throw it to try and get people to upgrade but the registry settings do exist to modify this behavior).

You can check your Cascade Settings. The Cascade settings on your models could be causing this. I removed Cascade Settings (Essentially not allowing Cascade Inserts/Updates) and this solved my problem

I don't know much about the MySQL command line interface, but assuming you only need help with the bashing, you should try to either swap the commands around like so:

myvariable=$(echo "SELECT A, B, C FROM table_a" | mysql database -u $user -p$password)

which echos the string into MySQL. Or, you can be more fancy and use some new bash-features (the here string)

myvariable=$(mysql database -u $user -p$password<<<"SELECT A, B, C FROM table_a")

resulting in the same thing (assuming you're using a recent enough bash version), without involving echo.

Please note that the -p$password is not a typo, but is the way MySQL expects passwords to be entered through the command line (with no space between the option and value).

Note that myvariable will contain everything that MySQL outputs on standard out (usually everything but error messages), including any and all column headers, ASCII-art frames and so on, which may or may not be what you want.

EDIT:
As has been noted, there appears to be a -e parameter to MySQL, I'd go for that one, definitely.

Use of whitespace in RE is a pain, but I believe they work. The OP's problem can also be solved using StringTokenizer or the split() method. However, to use RE (uncomment the println() to view how the matcher is breaking up the String), here is a sample code:

import java.util.regex.*;

public class Two21WS {
    private String  str = "";
    private Pattern pattern = Pattern.compile ("\\s{2,}");  // multiple spaces

    public Two21WS (String s) {
            StringBuffer sb = new StringBuffer();
            Matcher matcher = pattern.matcher (s);
            int startNext = 0;
            while (matcher.find (startNext)) {
                    if (startNext == 0)
                            sb.append (s.substring (0, matcher.start()));
                    else
                            sb.append (s.substring (startNext, matcher.start()));
                    sb.append (" ");
                    startNext = matcher.end();
                    //System.out.println ("Start, end = " + matcher.start()+", "+matcher.end() +
                    //                      ", sb: \"" + sb.toString() + "\"");
            }
            sb.append (s.substring (startNext));
            str = sb.toString();
    }

    public String toString () {
            return str;
    }

    public static void main (String[] args) {
            String tester = " a    b      cdef     gh  ij   kl";
            System.out.println ("Initial: \"" + tester + "\"");
            System.out.println ("Two21WS: \"" + new Two21WS(tester) + "\"");
}}

It produces the following (compile with javac and run at the command prompt):

% java Two21WS Initial: " a b cdef gh ij kl" Two21WS: " a b cdef gh ij kl"

use

path_to_exe >> log_file

to see the output of your command also errors can be redirected with

path_to_exe &> log_file

also you can use

crontab -l

to check if your edits were saved.

Google led me to this solution (base64_encode). Hope this helps!

Both are data providers (API that your code will use to talk to a data source). Oledb which was introduced in 1998 was meant to be a replacement for ODBC (introduced in 1992)

Since c++11, you can use the standard library instead of FormatMessage:

#include <system_error>

std::string GetLastErrorAsString(){
    DWORD errorMessageID = ::GetLastError();
    if (errorMessageID == 0) {
        return std::string(); //No error message has been recorded
    } else {
        return std::system_category().message(errorMessageID);
    }
}

Try the format as dd-mon-yyyy, For example 02-08-2016 should be in the format '08-feb-2016'.

IfLoop's answer (and MatToufoutu's comment) work great for standalone variables, but I wanted to provide an answer for anyone trying to do something similar for individual entries in lists, tuples, or dictionaries.

Dictionaries

existing_dict = {"spam": 1, "eggs": 2}
existing_dict["foo"] = existing_dict["foo"] if "foo" in existing_dict else 3

Returns {"spam": 1, "eggs": 2, "foo": 3}

Lists

existing_list = ["spam","eggs"]
existing_list = existing_list if len(existing_list)==3 else 
                existing_list + ["foo"]

Returns ["spam", "eggs", "foo"]

Tuples

existing_tuple = ("spam","eggs")
existing_tuple = existing_tuple if len(existing_tuple)==3 else 
                 existing_tuple + ("foo",)

Returns ("spam", "eggs", "foo")

(Don't forget the comma in ("foo",) to define a "single" tuple.)

The lists and tuples solution will be more complicated if you want to do more than just check for length and append to the end. Nonetheless, this gives a flavor of what you can do.

An experiment to compare ElasticSearch and Solr

Run cmd and then run node server.js. In your example, you are trying to use the REPL to run your command, which is not going to work. The ellipsis is node.js expecting more tokens before closing the current scope (you can type code in and run it on the fly here)

It depends what you wanted to do with that column e.g. here's an example of appending a new column to a recordset which can be updated on the client side:

Sub MSDataShape_AddNewCol()

  Dim rs As ADODB.Recordset
  Set rs = CreateObject("ADODB.Recordset")
  With rs
    .ActiveConnection = _
    "Provider=MSDataShape;" & _
    "Data Provider=Microsoft.Jet.OLEDB.4.0;" & _
    "Data Source=C:\Tempo\New_Jet_DB.mdb"
    .Source = _
    "SHAPE {" & _
    " SELECT ExistingField" & _
    " FROM ExistingTable" & _
    " ORDER BY ExistingField" & _
    "} APPEND NEW adNumeric(5, 4) AS NewField"

    .LockType = adLockBatchOptimistic

    .Open

    Dim i As Long
    For i = 0 To .RecordCount - 1
      .Fields("NewField").Value = Round(.Fields("ExistingField").Value, 4)
      .MoveNext
    Next

    rs.Save "C:\rs.xml", adPersistXML

  End With
End Sub

>>you can write your code like

  if (TextUtils.isEmpty(username)) {
            editTextUserName.setError("Please enter username");
            editTextUserName.requestFocus();
            return;
        }

        if (TextUtils.isEmpty(password)) {
            editTextPassword.setError("Enter a password");
            editTextPassword.requestFocus();
            return;
        }

There should be no real world need for such a function anymore. This is mere academic interest.

As purely an exercise, this is a more functional way of doing it. It's an extension of @tfmontague's answer as I'd suggested adding a guard block there. But seeing as I feel compelled to ES6 and functionalise all the things, here's my pimped version. It complicates the logic as you have to map over the array and reduce over the object, but it avoids any mutations.

const cloner = (x) => {
    const recurseObj = x => (typeof x === 'object') ? cloner(x) : x
    const cloneObj = (y, k) => {
        y[k] = recurseObj(x[k])
        return y
    }
    // Guard blocks
    // Add extra for Date / RegExp if you want
    if (!x) {
        return x
    }
    if (Array.isArray(x)) {
        return x.map(recurseObj)
    }
    return Object.keys(x).reduce(cloneObj, {})
}
const tests = [
    null,
    [],
    {},
    [1,2,3],
    [1,2,3, null],
    [1,2,3, null, {}],
    [new Date('2001-01-01')], // FAIL doesn't work with Date
    {x:'', y: {yx: 'zz', yy: null}, z: [1,2,3,null]},
    {
        obj : new function() {
            this.name = "Object test";
        }
    } // FAIL doesn't handle functions
]
tests.map((x,i) => console.log(i, cloner(x)))

In Qt5 you should use QtWidgets instead of QtGui

#include <QtGui/QComboBox>     // incorrect in QT5
#include <QtWidgets/QComboBox>    // correct in QT5

Or

#include <QtGui/QStringListModel>    // incorrect in QT5
#include <QtCore/QStringListModel>    // correct in QT5

A little bug with indexcolumn in alexander's answer: We need to take care of "not found" column:

int GetColumnIndexByName(GridViewRow row, string columnName)
{
    int columnIndex = 0;
    int foundIndex=-1;
    foreach (DataControlFieldCell cell in row.Cells)
    {
        if (cell.ContainingField is BoundField)
        {
            if (((BoundField)cell.ContainingField).DataField.Equals(columnName))
            {
                foundIndex=columnIndex;
                break;
            }
        }
        columnIndex++; // keep adding 1 while we don't have the correct name
    }
    return foundIndex;
}

and

protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        int index = GetColumnIndexByName(e.Row, "myDataField");
        if( index>0)
        {
            string columnValue = e.Row.Cells[index].Text;
        }
    }
}

It might be useful to make an extension in Swift for this.

Swift 4 and Swift 5:

Swift extension (e.g. in a UITableViewExtension.swift file):

import UIKit

extension UITableView {

    func deselectSelectedRow(animated: Bool)
    {
        if let indexPathForSelectedRow = self.indexPathForSelectedRow {
            self.deselectRow(at: indexPathForSelectedRow, animated: animated)
        }
    }

}

Use e.g.:

override func viewWillAppear(_ animated: Bool)
{
    super.viewWillAppear(animated)

    self.tableView.deselectSelectedRow(animated: true)
}

Here are a few things you need to do:

1-Download the library if you haven't already done that.

2- Import into Eclipse.

3- Set you project to use the library: Project-> Properties -> Android -> Scroll down to Library section, click Add... and select viewpagerindicator.

4- Now you should be able to import com.viewpagerindicator.TitlePageIndicator.

Now about implementing this without using fragments:

In the sample that comes with viewpagerindicatior, you can see that the library is being used with a ViewPager which has a FragmentPagerAdapter.

But in fact the library itself is Fragment independant. It just needs a ViewPager. So just use a PagerAdapter instead of a FragmentPagerAdapter and you're good to go.

Possible duplicate: Check if an element has event listener on it. No jQuery Please find my answer there.

Basically here is the trick for Chromium (Chrome) browser:

getEventListeners(document.querySelector('your-element-selector'));

Looks like /e option is what you need, it'll skip same files/directories.

robocopy c:\data c:\backup /e

If you run the command twice, you'll see the second round is much faster since it skips a lot of things.

The simplest way to do it would be something like:

throw new java.lang.Exception();

However, the following lines would be unreachable in your code. So, we have two ways:

1. Throw a generic exception at the bottom of the method.
2. Throw a custom exception in case you don't want to do 1.

@niutech I was having the similar issue which is caused by Rocket Loader Module by Cloudflare. Just disable it for the website and it will sort out all your related issues.

Also, you can use bool method(s)

Query :

DataTable tempData = (DataTable)grdUsageRecords.DataSource;
var query = from r in tempData.AsEnumerable()
            where isValid(Field<string>("UserName"))// && otherMethod() && otherMethod2()                           
            select r;   

        DataTable newDT = query.CopyToDataTable();

Method:

bool isValid(string userName)
{
    if(userName == "XXXX" || userName == "YYYY")
        return false;
    else return true;
}

From all I have read you cannot do exactly what you want without javascript. If you float left before text

<div style="float:left;">widget</div> here is some CONTENT, etc.

Your content wraps as expected. But your widget is in the top left. If you instead put the float after the content

here is some CONTENT, etc. <div style="float:left;">widget</div>

Then your content will wrap the last line to the right of the widget if the last line of content can fit to the right of the widget, otherwise no wrapping is done. To make borders and backgrounds actually include the floated area in the previous example, most people add:

here is some CONTENT, etc. <div style="float:left;">widget</div><div style="clear:both;"></div>

In your question you are using bootstrap which just adds row-fluid::after { content: ""} which resolves the border/background issue.

Moving your content up will give you the one line wrap : http://jsfiddle.net/jJNPY/34/

  <div class="container-fluid">
  <div class="row-fluid">
    <div class="offset1 span8 pull-right">
    ... Widget 1...
    </div>
    .... a lot of content ....
    <div class="span8" style="margin-left: 0;">
    ... Widget 2...
    </div>


  </div>

A workaround is to use a willAnswer() method.

For example the following works (and doesn't throw a MockitoException but actually throws a checked Exception as required here) using BDDMockito:

given(someObj.someMethod(stringArg1)).willAnswer( invocation -> { throw new Exception("abc msg"); });

The equivalent for plain Mockito would to use the doAnswer method

YES YOU CAN do it!! It's a little tricky way ; ) (it almost works on ios)

var iframe = document.createElement("IFRAME");
iframe.setAttribute("src", 'data:text/plain,');
document.documentElement.appendChild(iframe);
if(window.frames[0].window.confirm("Are you sure?")){
    // what to do if answer "YES"
}else{
    // what to do if answer "NO"
}

Enjoy it!

Here is another solution to change the location using href and clear the hash without scrolling.

The magic solution is explained here. Specs here.

const hash = window.location.hash;
history.scrollRestoration = 'manual';
window.location.href = hash;    
history.pushState('', document.title, window.location.pathname);

NOTE: The proposed API is now part of WhatWG HTML Living Standard

The accepted answer didn't work for me as my page jumped slightly on click, messing up my scroll animation.

I decided to update the entire URL using window.history.replaceState rather than using the window.location.hash method. Thus circumventing the hashChange event fired by the browser.

// Only fire when URL has anchor
$('a[href*="#"]:not([href="#"])').on('click', function(event) {

    // Prevent default anchor handling (which causes the page-jumping)
    event.preventDefault();

    if ( location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname ) {
        var target = $(this.hash);
        target = target.length ? target : $('[name=' + this.hash.slice(1) +']');

        if ( target.length ) {    
            // Smooth scrolling to anchor
            $('html, body').animate({
                scrollTop: target.offset().top
            }, 1000);

            // Update URL
            window.history.replaceState("", document.title, window.location.href.replace(location.hash, "") + this.hash);
        }
    }
});

Put the line $this->db->order_by("course_name","desc"); at top of your query. Like

$this->db->order_by("course_name","desc");$this->db->select('*');
$this->db->where('tennant_id',$tennant_id);
$this->db->from('courses');
$query=$this->db->get();
return $query->result();

JavaScript way - this worked for me.

<script>
$(document).ready(function() {
   $('#YourTableId').find('*').each(function () { $(this).attr("disabled", true); });
});
</script>

Reason:

1. $('#YourTableId').find('*') -> this returns all the tags.

2. $('#YourTableId').find('*').each(function () { $(this).attr("disabled", true); }); iterates over all objects captured in this and disable input tags.

Analysis (Debugging):

1. form:radiobutton is internally considered as an "input" tag.

2. Like in the above function(), if you try printing document.write(this.tagName);

3. Wherever, in tags it finds radio buttons, it returns an input tag.

So, above code line can be more optimized for radio button tags, by replacing * with input: $('#YourTableId').find('input').each(function () { $(this).attr("disabled", true); });

matcher.find() does what you needed. Example:

Pattern.compile("stores.*store.*product").matcher(someString).find();

I used the plugin Smooth Scroll, at http://plugins.jquery.com/smooth-scroll/. With this plugin all you need to include is a link to jQuery and to the plugin code:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="javascript/smoothscroll.js"></script>

(the links need to have the class smoothScroll to work).

Another feature of Smooth Scroll is that the ancor name is not displayed in the URL!

I'm quite a beginner in Python and I found the answer of Anand was very good but quite complicated to me, so I try to reformulate :

1) insert and append methods are not specific to sys.path and as in other languages they add an item into a list or array and :
* append(item) add item to the end of the list,
* insert(n, item) inserts the item at the nth position in the list (0 at the beginning, 1 after the first element, etc ...).

2) As Anand said, python search the import files in each directory of the path in the order of the path, so :
* If you have no file name collisions, the order of the path has no impact,
* If you look after a function already defined in the path and you use append to add your path, you will not get your function but the predefined one.

But I think that it is better to use append and not insert to not overload the standard behaviour of Python, and use non-ambiguous names for your files and methods.

If you are simply mapping an Integer to an int then you should consider using parallelism, since your mapping logic does not rely on any variables outside its scope.

int[] arr = list.parallelStream().mapToInt(Integer::intValue).toArray();

Just be aware of this

Note that parallelism is not automatically faster than performing operations serially, although it can be if you have enough data and processor cores. While aggregate operations enable you to more easily implement parallelism, it is still your responsibility to determine if your application is suitable for parallelism.

There are two ways to map Integers to their primitive form:

1. Via a ToIntFunction.

   mapToInt(Integer::intValue)
   

2. Via explicit unboxing with lambda expression.

   mapToInt(i -> i.intValue())
   

3. Via implicit (auto-) unboxing with lambda expression.

   mapToInt(i -> i)
   

Given a list with a null value

List<Integer> list = Arrays.asList(1, 2, null, 4, 5);

Here are three options to handle null:

1. Filter out the null values before mapping.

   int[] arr = list.parallelStream().filter(Objects::nonNull).mapToInt(Integer::intValue).toArray();
   

2. Map the null values to a default value.

   int[] arr = list.parallelStream().map(i -> i == null ? -1 : i).mapToInt(Integer::intValue).toArray();
   

3. Handle null inside the lambda expression.

   int[] arr = list.parallelStream().mapToInt(i -> i == null ? -1 : i.intValue()).toArray();
   

As I just figured, in case you have a model fitted on multiple linear regression, the above mentioned solution won't work.

You have to create your line manually as a dataframe that contains predicted values for your original dataframe (in your case data).

It would look like this:

# read dataset
df = mtcars

# create multiple linear model
lm_fit <- lm(mpg ~ cyl + hp, data=df)
summary(lm_fit)

# save predictions of the model in the new data frame 
# together with variable you want to plot against
predicted_df <- data.frame(mpg_pred = predict(lm_fit, df), hp=df$hp)

# this is the predicted line of multiple linear regression
ggplot(data = df, aes(x = mpg, y = hp)) + 
  geom_point(color='blue') +
  geom_line(color='red',data = predicted_df, aes(x=mpg_pred, y=hp))

# this is predicted line comparing only chosen variables
ggplot(data = df, aes(x = mpg, y = hp)) + 
  geom_point(color='blue') +
  geom_smooth(method = "lm", se = FALSE)

If you want the output to print to the terminal it is best to use Rscript

Rscript a.R

Note that when using R CMD BATCH a.R that instead of redirecting output to standard out and displaying on the terminal a new file called a.Rout will be created.

R CMD BATCH a.R
# Check the output
cat a.Rout

One other thing to note about using Rscript is that it doesn't load the methods package by default which can cause confusion. So if you're relying on anything that methods provides you'll want to load it explicitly in your script.

If you really want to use the ./a.R way of calling the script you could add an appropriate #! to the top of the script

#!/usr/bin/env Rscript
sayHello <- function(){
   print('hello')
}

sayHello()

I will also note that if you're running on a *unix system there is the useful littler package which provides easy command line piping to R. It may be necessary to use littler to run shiny apps via a script? Further details can be found in this question.

I tried to run insertion of random data into MyISAM and InnoDB tables. The result was quite shocking. MyISAM needed a few seconds less for inserting 1 million rows than InnoDB for just 10 thousand!

I think it is important to consider that, to a browser, 401 initiates an authentication dialog for the user to enter new credentials, while 403 does not. Browsers think that, if a 401 is returned, then the user should re-authenticate. So 401 stands for invalid authentication while 403 stands for a lack of permission.

Here are some cases under that logic where an error would be returned from authentication or authorization, with important phrases bolded.

• A resource requires authentication but no credentials were specified.

401: The client should specify credentials.

• The specified credentials are in an invalid format.

400: That's neither 401 nor 403, as syntax errors should always return 400.

• The specified credentials reference a user which does not exist.

401: The client should specify valid credentials.

• The specified credentials are invalid but specify a valid user (or don't specify a user if a specified user is not required).

401: Again, the client should specify valid credentials.

• The specified credentials have expired.

401: This is practically the same as having invalid credentials in general, so the client should specify valid credentials.

• The specified credentials are completely valid but do not suffice the particular resource, though it is possible that credentials with more permission could.

403: Specifying valid credentials would not grant access to the resource, as the current credentials are already valid but only do not have permission.

• The particular resource is inaccessible regardless of credentials.

403: This is regardless of credentials, so specifying valid credentials cannot help.

• The specified credentials are completely valid but the particular client is blocked from using them.

403: If the client is blocked, specifying new credentials will not do anything.

$ is a function provided by the jQuery library, it won't be available unless you have loaded the jQuery library.

You need to add jQuery (typically with a <script> element which can point at a local copy of the library or one hosted on a CDN). Make sure you are using a current and supported version: Many answers on this question recommend using 1.x or 2.x versions of jQuery which are no longer supported and have known security issues.

<script src="/path/to/jquery.js"></script>

Make sure you load jQuery before you run any script which depends on it.

The jQuery homepage will have a link to download the current version of the library (at the time of writing it is 3.5.1 but that may change by the time you read this).

Further down the page you will find a section on using jQuery with a CDN which links to a number of places that will host the library for you.

(NB: Some other libraries provide a $ function, and browsers have native $ variables which are only available in the Developer Tools Console, but this question isn't about those).

In my case, I took an android project from one computer to another and had this problem. What worked for me was a combination of some of the answers I've seen:

• Remove the copy of the appcompat library that was in the libs folder of the workspace
• Install sdk 21
• Change the project properties to use that sdk build
• Set up and start an emulator compatible with sdks 21
• Update the Run Configuration to prompt for device to run on & choose Run

Mine ran fine after these steps.

var data = {
    "items": [{
        "id": 1,
        "category": "cat1"
    }, {
        "id": 2,
        "category": "cat2"
    }, {
        "id": 3,
        "category": "cat1"
    }]
};

var returnedData = $.grep(data.items, function (element, index) {
    return element.id == 1;
});


alert(returnedData[0].id + "  " + returnedData[0].category);

The returnedData is returning an array of objects, so you can access it by array index.

http://jsfiddle.net/wyfr8/913/

Assign the second variable for the $.each function() as well, makes it lot easier as it'll provide you the data (so you won't have to work with the indicies).

$.each(json, function(arrayID,group) {
            console.log('<a href="'+group.GROUP_ID+'">');
    $.each(group.EVENTS, function(eventID,eventData) {
            console.log('<p>'+eventData.SHORT_DESC+'</p>');
     });
});

Should print out everything you were trying in your question.

edit renamed the variables to make it bit easier to understand what is what.

I've tried the other answers listed above, but they are very far from decent solutions when dealing with large files -- especially once a single line's size occupies more than ~1/4 of available RAM.

Both bash and awk slurp the entire line, even though for this problem it's not needed. Bash will error out once a line is too long, even if you have enough memory.

I've implemented an extremely simple, fairly unoptimized python script that when tested with large files (~4 GB per line) doesn't slurp, and is by far a better solution than those given.

If this is time critical code for production, you can rewrite the ideas in C or perform better optimizations on the read call (instead of only reading a single byte at a time), after testing that this is indeed a bottleneck.

Code assumes newline is a linefeed character, which is a good assumption for Unix, but YMMV on Mac OS/Windows. Be sure the file ends with a linefeed to ensure the last line character count isn't overlooked.

from sys import stdin, exit

counter = 0
while True:
    byte = stdin.buffer.read(1)
    counter += 1
    if not byte:
        exit()
    if byte == b'\x0a':
        print(counter-1)
        counter = 0

Use the default version:

Collections.sort(myarrayList);

Of course this requires that your Elements implement Comparable, but the same holds true for the version you mentioned.

BTW: you should use generics in your code, that way you get compile-time errors if your class doesn't implement Comparable. And compile-time errors are much better than the runtime errors you'll get otherwise.

List<MyClass> list = new ArrayList<MyClass>();
// now fill up the list

// compile error here unless MyClass implements Comparable
Collections.sort(list); 

max_allowed_packet is set in mysql config, not on php side

[mysqld]
max_allowed_packet=16M 

You can see it's curent value in mysql like this:

SHOW VARIABLES LIKE 'max_allowed_packet';

You can try to change it like this, but it's unlikely this will work on shared hosting:

SET GLOBAL max_allowed_packet=16777216;

You can read about it here http://dev.mysql.com/doc/refman/5.1/en/packet-too-large.html

EDIT

The [mysqld] is necessary to make the max_allowed_packet working since at least mysql version 5.5.

Recently setup an instance on AWS EC2 with Drupal and Solr Search Engine, which required 32M max_allowed_packet. It you set the value under [mysqld_safe] (which is default settings came with the mysql installation) mode in /etc/my.cnf, it did no work. I did not dig into the problem. But after I change it to [mysqld] and restarted the mysqld, it worked.

There is an issue that if you close the dialog it will execute the onCloseCallback function. This is a better design.

function jAlert2(outputMsg, titleMsg, onCloseCallback) {
    if (!titleMsg)
        titleMsg = 'Alert';

    if (!outputMsg)
        outputMsg = 'No Message to Display.';

    $("<div></div>").html(outputMsg).dialog({
        title: titleMsg,
        resizable: false,
        modal: true,
        buttons: {
            "OK": onCloseCallback,
            "Cancel": function() {
          $( this ).dialog( "destroy" );
            }

        },
    });

just setting width and adding float worked for me :-)

width:100%;
float:left;

Although it is not explicitly specified for setTimestamp(int parameterIndex, Timestamp x) drivers have to follow the rules established by the setTimestamp(int parameterIndex, Timestamp x, Calendar cal) javadoc:

Sets the designated parameter to the given java.sql.Timestamp value, using the given Calendar object. The driver uses the Calendar object to construct an SQL TIMESTAMP value, which the driver then sends to the database. With a Calendar object, the driver can calculate the timestamp taking into account a custom time zone. If no Calendar object is specified, the driver uses the default time zone, which is that of the virtual machine running the application.

When you call with setTimestamp(int parameterIndex, Timestamp x) the JDBC driver uses the time zone of the virtual machine to calculate the date and time of the timestamp in that time zone. This date and time is what is stored in the database, and if the database column does not store time zone information, then any information about the zone is lost (which means it is up to the application(s) using the database to use the same time zone consistently or come up with another scheme to discern timezone (ie store in a separate column).

For example: Your local time zone is GMT+2. You store "2012-12-25 10:00:00 UTC". The actual value stored in the database is "2012-12-25 12:00:00". You retrieve it again: you get it back again as "2012-12-25 10:00:00 UTC" (but only if you retrieve it using getTimestamp(..)), but when another application accesses the database in time zone GMT+0, it will retrieve the timestamp as "2012-12-25 12:00:00 UTC".

If you want to store it in a different timezone, then you need to use the setTimestamp(int parameterIndex, Timestamp x, Calendar cal) with a Calendar instance in the required timezone. Just make sure you also use the equivalent getter with the same time zone when retrieving values (if you use a TIMESTAMP without timezone information in your database).

So, assuming you want to store the actual GMT timezone, you need to use:

Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
stmt.setTimestamp(11, tsSchedStartTime, cal);

With JDBC 4.2 a compliant driver should support java.time.LocalDateTime (and java.time.LocalTime) for TIMESTAMP (and TIME) through get/set/updateObject. The java.time.Local* classes are without time zones, so no conversion needs to be applied (although that might open a new set of problems if your code did assume a specific time zone).

if you have the file inside a dirrectory called uploads in your project. bellow code can be used.

Path root = Paths.get("uploads");
File existingFile = new File(this.root.resolve("img.png").toUri());

if (existingFile.exists() && existingFile.isFile()) {
     existingFile.delete();
   }

OR

If it is inside a different directory this solution can be used.

File existingFile = new File("D:\\<path>\\img.png");

if (existingFile.exists() && existingFile.isFile()) {
    existingFile.delete();
  }

I found my own answer. It is very late now but I want to share it with you. I implement this interface:

import android.text.TextWatcher;


public abstract class MinMaxTextWatcher implements TextWatcher {
    int min, max;
    public MinMaxTextWatcher(int min, int max) {
        super();
        this.min = min;
        this.max = max;
    }

}

And then implement it in this way inside your activity:

private void limitEditText(final EditText ed, int min, int max) {
    ed.addTextChangedListener(new MinMaxTextWatcher(min, max) {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {

        }

        @Override
        public void afterTextChanged(Editable s) {
            String str = s.toString();
            int n = 0;
            try {
                n = Integer.parseInt(str);
                if(n < min) {
                    ed.setText(min);
                    Toast.makeText(getApplicationContext(), "Minimum allowed is " + min, Toast.LENGTH_SHORT).show();
                }
                else if(n > max) {
                    ed.setText("" + max);
                    Toast.makeText(getApplicationContext(), "Maximum allowed is " + max, Toast.LENGTH_SHORT).show();
                }
            }
            catch(NumberFormatException nfe) {
                ed.setText("" + min);
                Toast.makeText(getApplicationContext(), "Bad format for number!" + max, Toast.LENGTH_SHORT).show();
            }
        }
    });
}

This is a very simple answer, if any better please tell me.

getActivity().getSupportFragmentManager().beginTransaction().replace(GeneralInfo.this.getId(), new GeneralInfo()).commit();

GeneralInfo it's my Fragment class GeneralInfo.java

I put it as a method in the fragment class:

public void Reload(){
    getActivity().getSupportFragmentManager().beginTransaction().replace(LogActivity.this.getId(), new LogActivity()).commit();
}

img
{
    max-width: 100%;
    min-width: 300px;
    height: auto;
}

If you need to set the credentials on the fly, have a look at this source:

http://spc3.codeplex.com/SourceControl/changeset/view/57957#1015709

private ICredentials BuildCredentials(string siteurl, string username, string password, string authtype) {
    NetworkCredential cred;
    if (username.Contains(@"\")) {
        string domain = username.Substring(0, username.IndexOf(@"\"));
        username = username.Substring(username.IndexOf(@"\") + 1);
        cred = new System.Net.NetworkCredential(username, password, domain);
    } else {
        cred = new System.Net.NetworkCredential(username, password);
    }
    CredentialCache cache = new CredentialCache();
    if (authtype.Contains(":")) {
        authtype = authtype.Substring(authtype.IndexOf(":") + 1); //remove the TMG: prefix
    }
    cache.Add(new Uri(siteurl), authtype, cred);
    return cache;
}

sum is used to add elements; nrow is used to count the number of rows in a rectangular array (typically a matrix or data.frame); length is used to count the number of elements in a vector. You need to apply these functions correctly.

Let's assume your data is a data frame named "dat". Correct solutions:

nrow(dat[dat$sCode == "CA",])
length(dat$sCode[dat$sCode == "CA"])
sum(dat$sCode == "CA")

TryGetValue will already assign the default value for the type to the dictionary, so you can just use:

dictionary.TryGetValue(key, out value);

and just ignore the return value. However, that really will just return default(TValue), not some custom default value (nor, more usefully, the result of executing a delegate). There's nothing more powerful built into the framework. I would suggest two extension methods:

public static TValue GetValueOrDefault<TKey, TValue>
    (this IDictionary<TKey, TValue> dictionary, 
     TKey key,
     TValue defaultValue)
{
    TValue value;
    return dictionary.TryGetValue(key, out value) ? value : defaultValue;
}

public static TValue GetValueOrDefault<TKey, TValue>
    (this IDictionary<TKey, TValue> dictionary,
     TKey key,
     Func<TValue> defaultValueProvider)
{
    TValue value;
    return dictionary.TryGetValue(key, out value) ? value
         : defaultValueProvider();
}

(You may want to put argument checking in, of course :)

The below seems to work for me as well (tested from node.js):

var isFunction = function(o) {
     return Function.prototype.isPrototypeOf(o);
};

console.log(isFunction(function(){})); // true
console.log(isFunction({})); // false

I think buffers are e.g. useful when interfacing python to native libraries. (Guido van Rossum explains buffer in this mailinglist post).

For example, numpy seems to use buffer for efficient data storage:

import numpy
a = numpy.ndarray(1000000)

the a.data is a:

<read-write buffer for 0x1d7b410, size 8000000, offset 0 at 0x1e353b0>

As everyone else told you, you can convert it directly... UNLESS you meant something like "how can I convert an ASCII Extended character to its UTF-16 or UTF-32 value". This is a TOTALLY different question (one at least as good). And one quite difficult, if I remember correctly, if you are using only "pure" C. Then you could start here: https://stackoverflow.com/questions/114611/what-is-the-best-unicode-library-for-c/114643#114643

(for ASCII Extended I mean one of the many "extensions" to the ASCII set. The 0-127 characters of the base ASCII set are directly convertible to Unicode, while the 128-255 are not.). For example ISO_8859-1 http://en.wikipedia.org/wiki/ISO_8859-1 is an 8 bit extensions to the 7 bit ASCII set, or the (quite famous) codepages 437 and 850.

Extracted from the reference How to Iterate Over a Map in Java:

There are several ways of iterating over a Map in Java. Let's go over the most common methods and review their advantages and disadvantages. Since all maps in Java implement the Map interface, the following techniques will work for any map implementation (HashMap, TreeMap, LinkedHashMap, Hashtable, etc.)

Method #1: Iterating over entries using a For-Each loop.

This is the most common method and is preferable in most cases. It should be used if you need both map keys and values in the loop.

Map<Integer, Integer> map = new HashMap<Integer, Integer>();
for (Map.Entry<Integer, Integer> entry : map.entrySet()) {
    System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());
}

Note that the For-Each loop was introduced in Java 5, so this method is working only in newer versions of the language. Also a For-Each loop will throw NullPointerException if you try to iterate over a map that is null, so before iterating you should always check for null references.

Method #2: Iterating over keys or values using a For-Each loop.

If you need only keys or values from the map, you can iterate over keySet or values instead of entrySet.

Map<Integer, Integer> map = new HashMap<Integer, Integer>();

// Iterating over keys only
for (Integer key : map.keySet()) {
    System.out.println("Key = " + key);
}

// Iterating over values only
for (Integer value : map.values()) {
    System.out.println("Value = " + value);
}

This method gives a slight performance advantage over entrySet iteration (about 10% faster) and is more clean.

Method #3: Iterating using Iterator.

Using Generics:

Map<Integer, Integer> map = new HashMap<Integer, Integer>();
Iterator<Map.Entry<Integer, Integer>> entries = map.entrySet().iterator();
while (entries.hasNext()) {
    Map.Entry<Integer, Integer> entry = entries.next();
    System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());
}

Without Generics:

Map map = new HashMap();
Iterator entries = map.entrySet().iterator();
while (entries.hasNext()) {
    Map.Entry entry = (Map.Entry) entries.next();
    Integer key = (Integer)entry.getKey();
    Integer value = (Integer)entry.getValue();
    System.out.println("Key = " + key + ", Value = " + value);
}

You can also use same technique to iterate over keySet or values.

This method might look redundant, but it has its own advantages. First of all, it is the only way to iterate over a map in older versions of Java. The other important feature is that it is the only method that allows you to remove entries from the map during iteration by calling iterator.remove(). If you try to do this during For-Each iteration you will get "unpredictable results" according to Javadoc.

From a performance point of view this method is equal to a For-Each iteration.

Method #4: Iterating over keys and searching for values (inefficient).

Map<Integer, Integer> map = new HashMap<Integer, Integer>();
for (Integer key : map.keySet()) {
    Integer value = map.get(key);
    System.out.println("Key = " + key + ", Value = " + value);
}

This might look like a cleaner alternative for method #1, but in practice it is pretty slow and inefficient as getting values by a key might be time-consuming (this method in different Map implementations is 20%-200% slower than method #1). If you have FindBugs installed, it will detect this and warn you about inefficient iteration. This method should be avoided.

Conclusion:

If you need only keys or values from the map, use method #2. If you are stuck with older version of Java (less than 5) or planning to remove entries during iteration, you have to use method #3. Otherwise use method #1.

I had a similar problem, made all the more infuriating by simply being very SLOW to update. I couldn't get my changes to take effect while working on the site to save my life (trying all manner of clearing my browser cache and cookies), but if I came back to the site later in the day or opened another browser, there they were.

I also solved the problem by disabling the Supercacher software at my host's cpanel (Siteground). You can also use the "flush" button for individual directories to test if that's it before disabling.

I had downloaded it from http://gradle.org/gradle-download/. I use Homebrew, but I missed installing gradle using it.

To save some MBs by downloading it over again using Homebrew, I symlinked the gradle binary from the downloaded (and extracted) zip archive in the /usr/local/bin/. This is the same place where Homebrew symlinks all other binaries.

cd /usr/local/bin/
ln -s ~/Downloads/gradle-2.12/bin/gradle

Now check whether it works or not:

gradle -v

I have also seen:

if(length(obj)) {
  # do this if object has length
  # NULL has no length
}

I don't think it's great though. Because some vectors can be of length 0. character(0), logical(0), integer(0) and that might be treated as a NULL instead of an error.

To do this for a specific target, you can do the following:

target_compile_definitions(my_target PRIVATE FOO=1 BAR=1)

You should do this if you have more than one target that you're building and you don't want them all to use the same flags. Also see the official documentation on target_compile_definitions.

A bit of an explanation also appears in this forum thread.

There's a niche case where git mv remains very useful: when you want to change the casing of a file name on a case-insensitive file system. Both APFS (mac) and NTFS (windows) are, by default, case-insensitive (but case-preserving).

greg.kindel mentions this in a comment on CB Bailey's answer.

Suppose you are working on a mac and have a file Mytest.txt managed by git. You want to change the file name to MyTest.txt.

You could try:

$ mv Mytest.txt MyTest.txt
overwrite MyTest.txt? (y/n [n]) y
$ git status
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean

Oh dear. Git doesn't acknowledge there's been any change to the file.

You could work around this with by renaming the file completely then renaming it back:

$ mv Mytest.txt temp.txt
$ git rm Mytest.txt
rm 'Mytest.txt'
$ mv temp.txt MyTest.txt
$ git add MyTest.txt 
$ git status
On branch master
Your branch is up to date with 'origin/master'.

Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    renamed:    Mytest.txt -> MyTest.txt

Hurray!

Or you could save yourself all that bother by using git mv:

$ git mv Mytest.txt MyTest.txt
$ git status
On branch master
Your branch is up to date with 'origin/master'.

Changes to be committed:
  (use "git reset HEAD <file>..." to unstage)

    renamed:    Mytest.txt -> MyTest.txt

Using bash:

echo "|${COMMAND/$'\n'}|"

^{(Note that the control character in this question is a 'newline' (\n), not a carriage return (\r); the latter would have output REBOOT| on a single line.)}

Explanation

Uses the Bash Shell Parameter Expansion ${parameter/pattern/string}:

The pattern is expanded to produce a pattern just as in filename expansion. Parameter is expanded and the longest match of pattern against its value is replaced with string. [...] If string is null, matches of pattern are deleted and the / following pattern may be omitted.

Also uses the $'' ANSI-C quoting construct to specify a newline as $'\n'. Using a newline directly would work as well, though less pretty:

echo "|${COMMAND/
}|"

Full example

#!/bin/bash
COMMAND="$'\n'REBOOT"
echo "|${COMMAND/$'\n'}|"
# Outputs |REBOOT|

Or, using newlines:

#!/bin/bash
COMMAND="
REBOOT"
echo "|${COMMAND/
}|"
# Outputs |REBOOT|

Redirect PHP time programming:

 <?php
 header("Refresh:10;url=***-----índex.php--OR----URL-----");
 ?>

IF your data includes an arbitrary sequence of blank characters (tab, space), and you want to replace each sequence with one comma, use the following:

sed 's/[\t ]+/,/g' input_file

or

sed -r 's/[[:blank:]]+/,/g' input_file

If you want to replace sequence of space characters, which includes other characters such as carriage return and backspace, etc, then use the following:

sed -r 's/[[:space:]]+/,/g' input_file

Assuming you're targeting browsers that aren't IE8,

this would work as well:

function checkIfArrayIsUnique(myArray) 
{
    for (var i = 0; i < myArray.length; i++) 
    {
        if (myArray.indexOf(myArray[i]) !== myArray.lastIndexOf(myArray[i])) { 
            return false; 
        } 
    } 
    return true;   // this means not unique
}

Paul Randal has an exccellent discussion of this problem on his blog: http://www.sqlskills.com/blogs/paul/post/backup-log-with-no_log-use-abuse-and-undocumented-trace-flags-to-stop-it.aspx

Here's what you have to do if you are connecting MongoDB through Python

db.users.find({"username": {'$regex' : '.*' + 'Son' + '.*'}})

you may also use a variable name instead of 'Son' and therefore the string concatenation.

Instead of the modulo operator, which has slightly different semantics, for non-negative integers, you can use the remainder operator %. For your exact example:

if ((a % 2) == 0)
{
    isEven = true;
}
else
{
    isEven = false;
}

This can be simplified to a one-liner:

isEven = (a % 2) == 0;

First off, you need to implement INotifyPropertyChanged interface in your view model and raise the PropertyChanged event in the setter of the Rule property. Otherwise no control that binds to the SelectedRule property will "know" when it has been changed.

Then, your XAML

<TextBlock Text="{Binding Path=SelectedRule.Name}" />

is perfectly valid if this TextBlock is outside the ListBox's ItemTemplate and has the same DataContext as the ListBox.

Build.VERSION_CODES.LOLLIPOP should now be changed to BuildVersionCodes.Lollipop i.e:

} else {
    this.Control.Background = this.Resources.GetDrawable(Resource.Drawable.AddBorder);

Just several days ago, I met the same question just like yours. All code runs well on my local machine, but turns out error(noclassdeffound&initialize). So I post my solution, but I don't know why, I merely advance a possibility. I hope someone know will explain this.@John Vint Firstly, I'll show you my problem. My code has static variable and static block both. When I first met this problem, I tried John Vint's solution, and tried to catch the exception. However, I caught nothing. So I thought it is because the static variable(but now I know they are the same thing) and still found nothing. So, I try to find the difference between the linux machine and my computer. Then I found that this problem happens only when several threads run in one process(By the way, the linux machine has double cores and double processes). That means if there are two tasks(both uses the code which has static block or variables) run in the same process, it goes wrong, but if they run in different processes, both of them are ok. In the Linux machine, I use

mvn -U clean  test -Dtest=path 

to run a task, and because my static variable is to start a container(or maybe you initialize a new classloader), so it will stay until the jvm stop, and the jvm stops only when all the tasks in one process stop. Every task will start a new container(or classloader) and it makes the jvm confused. As a result, the error happens. So, how to solve it? My solution is to add a new command to the maven command, and make every task go to the same container.

-Dxxx.version=xxxxx #sorry can't post more

Maybe you have already solved this problem, but still hope it will help others who meet the same problem.

Similar to what Richard Detsch but with a bit easier to follow (works with packages as well)

Step 1: Unwrap the War file.

jar -xvf MyWar.war

Step 2: move into the directory

cd WEB-INF

Step 3: Run your main with all dependendecies

java -classpath "lib/*:classes/." my.packages.destination.FileToRun

You can also use the following code:

<?php
$filename = $_GET["nama"];
$contenttype = "application/force-download";
header("Content-Type: " . $contenttype);
header("Content-Disposition: attachment; filename=\"" . basename($filename) . "\";");
readfile("your file uploaded path".$filename);
exit();
?>

I had the same problem. What i found was i called my recieving object the same name as the class name. example:

const AspectType = new AspectType();

this screwed things up that way... hope this helps

If you don't want to run sudo then install ruby using homebrew

brew install ruby
export GEM_HOME="$HOME/.gem"
gem install rails

You may want to add export GEM_HOME="$HOME/.gem" to your ~/.bash_profile or .zshrc if you're using zsh

Note: RubyGems keeps old versions of gems, so feel free to do some cleaning after updating:

gem cleanup

kubectl rollout restart deployment myapp

This is the current way to trigger a rolling update and leave the old replica sets in place for other operations provided by kubectl rollout like rollbacks.

1. In Eclipse Select Help -> Marketplace

2. Enter "Maven" in Find box and click on Go button

3. Click on "Install" button for Maven Integration for Eclipse (Juno and newer)

With this, maven should get install without any problem.

wget -S -O - http://google.com works as expected for me, but with a caveat: the headers are considered debugging information and as such they are sent to the standard error rather than the standard output. If you are redirecting the standard output to a file or another process, you will only get the document contents.

You can try redirecting the standard error to the standard output as a possible solution. For example, in bash:

$ wget -q -S -O - 2>&1 | grep ...

or

$ wget -q -S -O - 1>wget.txt 2>&1

The -q option suppresses the progress bar and some other annoyingly chatty parts of the wget output.

The HashMap has no defined ordering of keys.

If you just want to temporarily change to another environment, use

source activate environment-name

(you can create environment-name with `conda create)

To change permanently, there is no method except creating a startup script that runs the above code.

Typically it's best to just create new environments. However, if you really want to change the Python version in the default environment, you can do so as follows:

First, make sure you have the latest version of conda by running

conda update conda

Then run

conda install python=3.5

This will attempt to update all your packages in your root environment to Python 3 versions. If it is not possible (e.g., because some package is not built for Python 3.5), it will give you an error message indicating which package(s) caused the issue.

If you installed packages with pip, you'll have to reinstall them.

element.get_attribute('innerHTML')

is it ok? yes, it will compile

is it recommended? no - .c files compile to .obj files, which are linked together after compilation (by the linker) into the executable (or library), so there is no need to include one .c file in another. What you probably want to do instead is to make a .h file that lists the functions/variables available in the other .c file, and include the .h file

The comparison needs to be evaluated fully inside EL ${ ... }, not outside.

<c:if test="${values.type eq 'object'}">

As to the docs, those ${} things are not JSTL, but EL (Expression Language) which is a whole subject at its own. JSTL (as every other JSP taglib) is just utilizing it. You can find some more EL examples here.

<c:if test="#{bean.booleanValue}" />
<c:if test="#{bean.intValue gt 10}" />
<c:if test="#{bean.objectValue eq null}" />
<c:if test="#{bean.stringValue ne 'someValue'}" />
<c:if test="#{not empty bean.collectionValue}" />
<c:if test="#{not bean.booleanValue and bean.intValue ne 0}" />
<c:if test="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

• Our EL wiki page

By the way, unrelated to the concrete problem, if I guess your intent right, you could also just call Object#getClass() and then Class#getSimpleName() instead of adding a custom getter.

<c:forEach items="${list}" var="value">
    <c:if test="${value['class'].simpleName eq 'Object'}">
        <!-- code here -->

The recommended way to create random integers with NumPy these days is to use numpy.random.Generator.integers. (documentation)

You JSON is not a valid string as P. Galbraith has told you above.

and here is the solution for it.

<?php 
$json_url = "http://api.testmagazine.com/test.php?type=menu";
$json = file_get_contents($json_url);
$json=str_replace('},

]",$json);
$data = json_decode($json);

echo "<pre>";
print_r($data);
echo "</pre>";
?>

Use this code it will work for you.

This thread is pretty old I suppose, but in case anyone else stumbles across this question... I had to grab a value from the selected row of a table, but I didn't want to show the column that row was from. I used hideCol, but had the same problem as Andy where it looked messy. To fix it (call it a hack) I just re-set the width of the grid.

jQuery(document).ready(function() {

       jQuery("#ItemGrid").jqGrid({ 
                ..., 
                width: 700,
                ...
        }).hideCol('StoreId').setGridWidth(700)

Since my row widths are automatic, when I reset the width of the table it reset the column widths but excluded the hidden one, so they filled in the gap.

I would use a UIAlertView with a UITextField subview. You can either add the text field manually or, in iOS 5, use one of the new methods.

It is better if you override the delete method for this. That way, you can incorporate DB transactions within the delete method itself. If you use the event way, you will have to cover your call of delete method with a DB transaction every time you call it.

In your User model.

public function delete()
{
    \DB::beginTransaction();

     $this
        ->photo()
        ->delete()
    ;

    $result = parent::delete();

    \DB::commit();

    return $result;
}

There is an open issue for this on their github page: https://github.com/npm/npm/issues/18712

This issue is most severe when developers are using different operating systems.

Discord doesn't allow colored text. Though, currently, you have two options to "mimic" colored text.

Option #1 (Markdown code-blocks)

Discord supports Markdown and uses highlight.js to highlight code-blocks. Some programming languages have specific color outputs from highlight.js and can be used to mimic colored output.

To use code-blocks, send a normal message in this format (Which follows Markdown's standard format).

```language
message
```

Languages that currently reproduce nice colors: prolog (red/orange), css (yellow).

Option #2 (Embeds)

Discord now supports Embeds and Webhooks, which can be used to display colored blocks, they also support markdown. For documentation on how to use Embeds, please read your lib's documentation.

If you have this problem in Windows 10, and you know you have premisions on folder (You could write before but it just started to print exception PermissionError recently).. You will need to install Windows updates... I hope someone will help this info.

It is possible to use a handler to do this, even in MVC4. Here's an example from one i made earlier:

public class ImageHandler : IHttpHandler
{
    byte[] bytes;

    public void ProcessRequest(HttpContext context)
    {
        int param;
        if (int.TryParse(context.Request.QueryString["id"], out param))
        {
            using (var db = new MusicLibContext())
            {
                if (param == -1)
                {
                    bytes = File.ReadAllBytes(HttpContext.Current.Server.MapPath("~/Images/add.png"));

                    context.Response.ContentType = "image/png";
                }
                else
                {
                    var data = (from x in db.Images
                                where x.ImageID == (short)param
                                select x).FirstOrDefault();

                    bytes = data.ImageData;

                    context.Response.ContentType = "image/" + data.ImageFileType;
                }

                context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
                context.Response.BinaryWrite(bytes);
                context.Response.Flush();
                context.Response.End();
            }
        }
        else
        {
            //image not found
        }
    }

    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}

In the view, i added the ID of the photo to the query string of the handler.

I think the problem is you have to use the ! to unbundle identifier

I have

override func prepareForSegue(segue: UIStoryboardSegue?, sender: AnyObject?) {
        if segue!.identifier == "Details" {
            let viewController:ViewController = segue!.destinationViewController as ViewController
            let indexPath = self.tableView.indexPathForSelectedRow()
            viewController.pinCode = self.exams[indexPath.row]

        }

    }

My understanding is that without the ! you just get a true or false value

Also the error can be solved by adding several flags, like -marm -mthumb-interwork. It was helpful for me to avoid this same error.

Command:

foo >> output.txt 2>&1

appends to the output.txt file, without replacing the content.

Just to propose a sed alternative. :) To skip first one million lines, try |sed '1,1000000d'.

Example:

$ perl -wle 'print for (1..1_000_005)'|sed '1,1000000d'
1000001
1000002
1000003
1000004
1000005

Have you got org.springframework.orm.hibernate3.support.OpenSessionInViewFilter configured in webapp's web.xml (assuming your application is a webapp), or wrapping calls accordingly?

It seems that the good-old ENVIRON awk built-in hash is not mentioned at all. An example of its usage:

$ X=Solaris awk 'BEGIN{print ENVIRON["X"], ENVIRON["TERM"]}'
Solaris rxvt

So I encountered a particular situation: I cloned a repository from gitlab, which contained a file larger than 100 mb, but was removed at some point in the git history. Then later when I added a new github private repo and tried to push to the new repo, I got the infamous 'file too large' error. By this point, I no longer had access to the original gitlab repo. However, I was still able to push to the new private github repo using bfg-repo-cleaner on a LOCAL repository on my machine:

$ cd ~
$ curl https://repo1.maven.org/maven2/com/madgag/bfg/1.13.0/bfg-1.13.0.jar > bfg.jar
$ cd my-project
$ git gc
$ cd ../
$ java -jar bfg.jar --strip-blobs-bigger-than 100M my-project
$ cd my-project
$ git reflog expire --expire=now --all && git gc --prune=now --aggressive
$ git remote -v # confirm origin is the remote you want to push to
$ git push origin master

I don't think that they really are random, but my guess is those are some hashes.

Whenever I need some random identifier, I usually use a GUID and convert it to its "naked" representation:

Guid.NewGuid().ToString("n");

unset($foo[0]); // remove item at index 0
$foo2 = array_values($foo); // 'reindex' array

convert element's textContent to lowercase with JS..

el.textContent = el.textContent.toLowerCase();

then just use css..

text-transform: capitalize;

[
      {
           id : '1',
           title: 'sample title',
           ....
      },
      {
           id : '2',
           title: 'sample title',
           ....
     },
      ...
 ]

Once I found Geany (Ubuntu), I switched from TextMate (OSX) and never looked back. Geany is a lean, clean, speedy IDE that can be used either as a text editor or a light-weight IDE. It supports not only text editing features (syntax highlighting, code folding, auto-completion, auto-closing, symbol lists, code navigation, directory tree, multi-tabbed open files etc.) but also normal IDE features such as simple project management, compile-build-run within the main window. Unlike TextMate, it has a Terminal screen within its own window; you do not have to go back and force between your editor window and terminal window. Unlike TextMate, it supports international languages. Unlike TextMate, it supports multi-platforms, Unlike TextMate, it is open-source and free. Geany is now my favorite C/Ruby/XML development tool.

In languages like Python, I would usually use a dictionary as it involves less overhead than creating a new class.

However, if I find myself constantly returning the same set of variables, then that probably involves a new class that I'll factor out.

I have an implementation as part of a spreadsheet project.

This code is not yet tested thoroughly, but anyone is welcome to use it.

As some of the answers noted though, your implementation can be much simpler if you actually have DSV or TSV file, as they disallow the use of the record and field separators in the values. CSV, on the other hand, can actually have commas and newlines inside a field, which breaks most regular expression and split-based approaches.

var CSV = {
    parse: function(csv, reviver) {
        reviver = reviver || function(r, c, v) { return v; };
        var chars = csv.split(''), c = 0, cc = chars.length, start, end, table = [], row;
        while (c < cc) {
            table.push(row = []);
            while (c < cc && '\r' !== chars[c] && '\n' !== chars[c]) {
                start = end = c;
                if ('"' === chars[c]){
                    start = end = ++c;
                    while (c < cc) {
                        if ('"' === chars[c]) {
                            if ('"' !== chars[c+1]) {
                                break;
                            }
                            else {
                                chars[++c] = ''; // unescape ""
                            }
                        }
                        end = ++c;
                    }
                    if ('"' === chars[c]) {
                        ++c;
                    }
                    while (c < cc && '\r' !== chars[c] && '\n' !== chars[c] && ',' !== chars[c]) {
                        ++c;
                    }
                } else {
                    while (c < cc && '\r' !== chars[c] && '\n' !== chars[c] && ',' !== chars[c]) {
                        end = ++c;
                    }
                }
                row.push(reviver(table.length-1, row.length, chars.slice(start, end).join('')));
                if (',' === chars[c]) {
                    ++c;
                }
            }
            if ('\r' === chars[c]) {
                ++c;
            }
            if ('\n' === chars[c]) {
                ++c;
            }
        }
        return table;
    },

    stringify: function(table, replacer) {
        replacer = replacer || function(r, c, v) { return v; };
        var csv = '', c, cc, r, rr = table.length, cell;
        for (r = 0; r < rr; ++r) {
            if (r) {
                csv += '\r\n';
            }
            for (c = 0, cc = table[r].length; c < cc; ++c) {
                if (c) {
                    csv += ',';
                }
                cell = replacer(r, c, table[r][c]);
                if (/[,\r\n"]/.test(cell)) {
                    cell = '"' + cell.replace(/"/g, '""') + '"';
                }
                csv += (cell || 0 === cell) ? cell : '';
            }
        }
        return csv;
    }
};

We can use LIMIT like bellow:

Model::take(20)->get();

Basically you have two options

scale_x_continuous(limits = c(-5000, 5000))

or

coord_cartesian(xlim = c(-5000, 5000)) 

Where the first removes all data points outside the given range and the second only adjusts the visible area. In most cases you would not see the difference, but if you fit anything to the data it would probably change the fitted values.

You can also use the shorthand function xlim (or ylim), which like the first option removes data points outside of the given range:

+ xlim(-5000, 5000)

For more information check the description of coord_cartesian.

The RStudio cheatsheet for ggplot2 makes this quite clear visually. Here is a small section of that cheatsheet:

Just as a addition. You can find the Catalina Paths in

->RUN->RUN CONFIGURATIONS->APACHE TOMCAT->ARGUMENTS

In the VM Arguments the Paths are listed and changeable

Sometimes it relates as

$ sysctl vm.overcommit_memory
vm.overcommit_memory = 2

If you set it to:

$ sysctl vm.overcommit_memory=0

It should work.

Alternatively, you can use mysqlclient or oursql. For oursql, use the oursql py3k series as my link points to.

You can import a bunch of .java files to your existing project without creating a new project. Here are the steps:

1. Right-click on the Default Package in the Project Manager pane underneath your project and choose Import
2. An Import Wizard window will display. Choose File system and select the Next button
3. You are now prompted to choose a file
4. Simply browse your folder with .java files in it
5. Select desired .java files
6. Click on Finish to finish the import wizard

Consider using a subquery:

from p in context.ParentTable 
let cCount =
(
  from c in context.ChildTable
  where p.ParentId == c.ChildParentId
  select c
).Count()
select new { ParentId = p.Key, Count = cCount } ;

If the query types are connected by an association, this simplifies to:

from p in context.ParentTable 
let cCount = p.Children.Count()
select new { ParentId = p.Key, Count = cCount } ;

Using directive it becomes easy and can be used throughout the application

HTML

<input type="text" placeholder="Enter value" numbersOnly>

As .keyCode() and .which() are deprecated, codes are checked using .key() Referred from

Directive:

@Directive({
   selector: "[numbersOnly]"
})

export class NumbersOnlyDirective {
  @Input() numbersOnly:boolean;

  navigationKeys: Array<string> = ['Backspace']; //Add keys as per requirement
  
  constructor(private _el: ElementRef) { }

  @HostListener('keydown', ['$event']) onKeyDown(e: KeyboardEvent) {
    
    if (
      // Allow: Delete, Backspace, Tab, Escape, Enter, etc
      this.navigationKeys.indexOf(e.key) > -1 || 
      (e.key === 'a' && e.ctrlKey === true) || // Allow: Ctrl+A
      (e.key === 'c' && e.ctrlKey === true) || // Allow: Ctrl+C
      (e.key === 'v' && e.ctrlKey === true) || // Allow: Ctrl+V
      (e.key === 'x' && e.ctrlKey === true) || // Allow: Ctrl+X
      (e.key === 'a' && e.metaKey === true) || // Cmd+A (Mac)
      (e.key === 'c' && e.metaKey === true) || // Cmd+C (Mac)
      (e.key === 'v' && e.metaKey === true) || // Cmd+V (Mac)
      (e.key === 'x' && e.metaKey === true) // Cmd+X (Mac)
    ) {
        return;  // let it happen, don't do anything
    }
    // Ensure that it is a number and stop the keypress
    if (e.key === ' ' || isNaN(Number(e.key))) {
      e.preventDefault();
    }
  }
}

That's correct, your response is an object with fields:

{
    "page": 1,
    "results": [ ... ]
}

So you in fact want to iterate the results field only:

this.data = res.json()['results'];

... or even easier:

this.data = res.json().results;

This behavior is related to Zone that is set - Internet/Intranet/etc and corresponding Security Level

You can change this by setting less secure Security Level (not recommended) or by customizing Display Mixed Content property

You can do that by following steps:

1. Click on Gear icon at the top of the browser window.
2. Select Internet Options.
3. Select the Security tab at the top.
4. Click the Custom Level... button.
5. Scroll about halfway down to the Miscellaneous heading (denoted by a "blank page" icon).
6. Under this heading is the option Display Mixed Content; set this to Enable/Prompt.
7. Click OK, then Yes when prompted to confirm the change, then OK to close the Options window.
8. Close and restart the browser.

Abstraction is the process where you "throw-away" unnecessary details from an entity you plan to capture/represent in your design and keep only the properties of the entity that are relevant to your domain.
Example: to represent car you would keep e.g. the model and price, current location and current speed and ignore color and number of seats etc.

Encapsulation is the "binding" of the properties and the operations that manipulate them in a single unit of abstraction (namely a class).
So the car would have accelarate stop that manipulate location and current speed etc.

For me I think there might be some issue in installing android NDK from android studio. I was able to resolve this in following manner

Downloaded android ndk from

https://developer.android.com/ndk/downloads/index.html

and placed inside ndk-bundle (where your android sdk is installed ). For more info check this screens.

https://app.box.com/s/dfi4h9k7v4h0tmbu3z9qnqx3d12fdejn

IEnumerable lambda extension:

public static class ListExtensions
{        
    public static IEnumerable<T> Distinct<T>(this IEnumerable<T> list, Func<T, int> hashCode)
    {
        Dictionary<int, T> hashCodeDic = new Dictionary<int, T>();

        list.ToList().ForEach(t => 
            {   
                var key = hashCode(t);
                if (!hashCodeDic.ContainsKey(key))
                    hashCodeDic.Add(key, t);
            });

        return hashCodeDic.Select(kvp => kvp.Value);
    }
}

Usage:

class Employee
{
    public string Name { get; set; }
    public int EmployeeID { get; set; }
}

//Add 5 employees to List
List<Employee> lst = new List<Employee>();

Employee e = new Employee { Name = "Shantanu", EmployeeID = 123456 };
lst.Add(e);
lst.Add(e);

Employee e1 = new Employee { Name = "Adam Warren", EmployeeID = 823456 };
lst.Add(e1);
//Add a space in the Name
Employee e2 = new Employee { Name = "Adam  Warren", EmployeeID = 823456 };
lst.Add(e2);
//Name is different case
Employee e3 = new Employee { Name = "adam warren", EmployeeID = 823456 };
lst.Add(e3);            

//Distinct (without IEqalityComparer<T>) - Returns 4 employees
var lstDistinct1 = lst.Distinct();

//Lambda Extension - Return 2 employees
var lstDistinct = lst.Distinct(employee => employee.EmployeeID.GetHashCode() ^ employee.Name.ToUpper().Replace(" ", "").GetHashCode()); 

Try this:

<script type="text/javascript">
$.fn.toggleFuncs = function() {
    var functions = Array.prototype.slice.call(arguments),
    _this = this.click(function(){
        var i = _this.data('func_count') || 0;
        functions[i%functions.length]();
        _this.data('func_count', i+1);
    });
}
$('$showmenu').toggleFuncs(
        function() {
           $( ".menu" ).toggle( "drop" );
            },
            function() {
                $( ".menu" ).toggle( "drop" );
            }
); 

</script>

First fuction is an alternative to JQuery deprecated toggle :) . Works good with JQuery 2.0.3 and JQuery UI 1.10.3

Use this Retrofit Client

    private var mContext:Context = context
    private var retrofit: Retrofit? = null

    val client: Retrofit?

                    .readTimeout(Constants.TIME_OUT, TimeUnit.SECONDS)
                    .writeTimeout(Constants.TIME_OUT, TimeUnit.SECONDS)
            client.addInterceptor(logging)
            client.interceptors().add(AddCookiesInterceptor(mContext))

            val gson = GsonBuilder().setDateFormat("yyyy-MM-dd'T'HH:mm:ssZ").create()
            if (retrofit == null) {

                retrofit = Retrofit.Builder()
                        .baseUrl(Constants.URL)
                        .addConverterFactory(GsonConverterFactory.create(gson))

No, an architect has a different job than a programmer. The architect is more concerned with nonfunctional ("ility") requirements. Like reliability, maintainability, security, and so on. (If you don't agree, consider this thought experiment: compare a CGI program written in C that does a complicated website, versus a Ruby on Rails implementation. They both have the same functional behavior; choosing an RoR architecture has what advantages.)

Generally, a "solution architect" is about the whole system -- hardware, software, and all -- which an "application architect" is working within a fixed platform, but the terms aren't that rigorous or well standardized.

If you are talking about the scrollbar that automatically appears on a div with overflow: scroll (or auto), then no, that's still a native scrollbar rendered by the browser using normal OS widgets, and not something that can be styled(*).

Whilst you can replace it with a proxy made out of stylable divs and JavaScript as suggested by Matt, I wouldn't recommend it for the general case. Script-driven scrollbars never quite behave exactly the same as real OS scrollbars, causing usability and accessibility problems.

(*: Except for the IE colouring styles, which I wouldn't really recommend either. Apart from being IE-only, using them forces IE to fall back from using nice scrollbar images from the current Windows theme to ugly old Win95-style scrollbars.)
