Regarding @Jon_Schneider's comment, if the column has blank cells just use COUNTA()

=INDEX(G2:G; COUNT**A**(G2:G))

Just adding some extra sorting if needed

=QUERY(A2:A,"select A, count(A) where A is not null group by A order by count(A) DESC label A 'Name', count(A) 'Count'",-1)

This is for those who want to overwrite the column cells quickly (without cutting and copying). This is the same as double-clicking the cell box but unlike double-clicking, it still works after the first try.

1. Select the column cell you would like to copy downwards
2. Press Ctrl+Shift+⇓ to select the cells below
3. Press Ctrl+Enter to copy the contents of the first cell into the cells below

BONUS:

The shortcut for going to the bottom-most content (to double-check the copy) is Ctrl+⇓. To go back up you can use Ctrl+⇑ but if your top rows are frozen you'll also have to press Enter a few times.

Select the range, press CONTROL+U and then press ?+RETURN.

mp = new MediaPlayer();
AssetFileDescriptor afd = mContext.getAssets().openFd(fileName);
mp.reset();

  public void onPrepared(MediaPlayer mp) {
    mp.start();
  }
});

If you would like to check in PHP , then you should do something like :

$query_s =mysql_query("SELECT YOURROWNAME from `YOURTABLENAME` where name = $name");
$ertom=mysql_fetch_array($query_s);
if ('' !== $ertom['YOURROWNAME']) {
  //do your action
  echo "It was filled";
} else { 
  echo "it was empty!";
}

Based on semver, you can use

• Hyphen Ranges X.Y.Z - A.B.C 1.2.3-2.3.4 Indicates >=1.2.3 <=2.3.4

• X-Ranges 1.2.x 1.X 1.2.*

• Tilde Ranges ~1.2.3 ~1.2 Indicates allowing patch-level changes or minor version changes.

• Caret Ranges ^1.2.3 ^0.2.5 ^0.0.4

  Allows changes that do not modify the left-most non-zero digit in the [major, minor, patch] tuple

  • ^1.2.x (means >=1.2.0 <2.0.0)
  • ^0.0.x (means >=0.0.0 <0.1.0)
  • ^0.0 (means >=0.0.0 <0.1.0)

For variable argument functions like printf and scanf, the arguments are promoted, for example, any smaller integer types are promoted to int, float is promoted to double.

scanf takes parameters of pointers, so the promotion rule takes no effect. It must use %f for float* and %lf for double*.

printf will never see a float argument, float is always promoted to double. The format specifier is %f. But C99 also says %lf is the same as %f in printf:

C99 §7.19.6.1 The fprintf function

l (ell) Specifies that a following d, i, o, u, x, or X conversion specifier applies to a long int or unsigned long int argument; that a following n conversion specifier applies to a pointer to a long int argument; that a following c conversion specifier applies to a wint_t argument; that a following s conversion specifier applies to a pointer to a wchar_t argument; or has no effect on a following a, A, e, E, f, F, g, or G conversion specifier.

This is my favourite way of decoding HTML characters. The advantage of using this code is that tags are also preserved.

function decodeHtml(html) {
    var txt = document.createElement("textarea");
    txt.innerHTML = html;
    return txt.value;
}

Example: http://jsfiddle.net/k65s3/

Input:

Entity:&nbsp;Bad attempt at XSS:<script>alert('new\nline?')</script><br>

Output:

Entity: Bad attempt at XSS:<script>alert('new\nline?')</script><br>

This answer is a complement to @Evert's on the legend position.

My first try on @Evert's solution failed due to overlaps of the legend and the subplot's title.

In fact, the overlaps are caused by fig.tight_layout(), which changes the subplots' layout without considering the figure legend. However, fig.tight_layout() is necessary.

In order to avoid the overlaps, we can tell fig.tight_layout() to leave spaces for the figure's legend by fig.tight_layout(rect=(0,0,1,0.9)).

Description of tight_layout() parameters.

You can't bind an event to the element before it exists, so you should do it in the onload event:

<html>
<head>
<script type="text/javascript">

window.onload = function() {

  document.getElementById('foo').addEventListener('click', function (e) {
    var img = document.createElement('img');
    img.setAttribute('src', 'http://blog.stackoverflow.com/wp-content/uploads/stackoverflow-logo-300.png');
    e.target.appendChild(img);
  });

};

</script>
</head>
<body>
<img id="foo" src="http://soulsnatcher.bplaced.net/LDRYh.jpg" alt="unfinished bingo card" />
</body>
</html>

A solution using list.index:

def indices(lst, element):
    result = []
    offset = -1
    while True:
        try:
            offset = lst.index(element, offset+1)
        except ValueError:
            return result
        result.append(offset)

It's much faster than the list comprehension with enumerate, for large lists. It is also much slower than the numpy solution if you already have the array, otherwise the cost of converting outweighs the speed gain (tested on integer lists with 100, 1000 and 10000 elements).

NOTE: A note of caution based on Chris_Rands' comment: this solution is faster than the list comprehension if the results are sufficiently sparse, but if the list has many instances of the element that is being searched (more than ~15% of the list, on a test with a list of 1000 integers), the list comprehension is faster.

An alternative approach would be:

df1 = sqlContext.createDataFrame(
    [(1, "a", 2.0), (2, "b", 3.0), (3, "c", 3.0)],
    ("x1", "x2", "x3"))

df2 = sqlContext.createDataFrame(
    [(1, "f", -1.0), (2, "b", 0.0)], ("x1", "x2", "x4"))

df = df1.join(df2, ['x1','x2'])
df.show()

which outputs:

+---+---+---+---+
| x1| x2| x3| x4|
+---+---+---+---+
|  2|  b|3.0|0.0|
+---+---+---+---+

With the main advantage being that the columns on which the tables are joined are not duplicated in the output, reducing the risk of encountering errors such as org.apache.spark.sql.AnalysisException: Reference 'x1' is ambiguous, could be: x1#50L, x1#57L.

Whenever the columns in the two tables have different names, (let's say in the example above, df2 has the columns y1, y2 and y4), you could use the following syntax:

df = df1.join(df2.withColumnRenamed('y1','x1').withColumnRenamed('y2','x2'), ['x1','x2'])

Similar to hute37's answer but using the purrr package. I think this tidyverse approach is simpler than the answer proposed by AbiK.

library(purrr)
map_dbl(df, ~sum(is.na(.)))

Note: the tilde (~) creates an anonymous function. And the '.' refers to the input for the anonymous function, in this case the data.frame df.

pthread_exit terminates the calling thread while pthread_join suspends execution of calling thread until target threads completes execution.

They are pretty much well explained in detail in the open group documentation:

• pthread_exit
• pthread_join

Here is the best Maven-Environment Setup tutorial for Windows, Unix and Mac Operating systems.

But in the last you have to set value of PATH variable as ";%M2_HOME%\bin" instead of "%M2%", because PATH variable is not able to reduce the value using "%M2%"

Packages and stored procedures in Oracle execute by default using the rights of the package/procedure OWNER, not the currently logged on user.

So if you call a package that creates a user for example, its the package owner, not the calling user that needs create user privilege. The caller just needs to have execute permission on the package.

If you would prefer that the package should be run using the calling user's permissions, then when creating the package you need to specify AUTHID CURRENT_USER

COALESCE(value [, ...])

The COALESCE function returns the first of its arguments that is not null.  
Null is returned only if all arguments are null. It is often
used to substitute a default value for null values when data is
retrieved for display.

Edit

Here's an example of COALESCE with your query:

SELECT AVG( price )
FROM(
      SELECT *, cume_dist() OVER ( ORDER BY price DESC ) FROM web_price_scan
      WHERE listing_Type = 'AARM'
        AND u_kbalikepartnumbers_id = 1000307
        AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
        AND COALESCE( price, 0 ) > ( SELECT AVG( COALESCE( price, 0 ) )* 0.50
                                     FROM ( SELECT *, cume_dist() OVER ( ORDER BY price DESC )
                                           FROM web_price_scan
                                           WHERE listing_Type='AARM'
                                             AND u_kbalikepartnumbers_id = 1000307
                                             AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
                                         ) g
                                    WHERE cume_dist < 0.50
                                  )
        AND COALESCE( price, 0 ) < ( SELECT AVG( COALESCE( price, 0 ) ) *2
                                     FROM( SELECT *, cume_dist() OVER ( ORDER BY price desc )
                                           FROM web_price_scan
                                           WHERE listing_Type='AARM'
                                             AND u_kbalikepartnumbers_id = 1000307
                                             AND ( EXTRACT( DAY FROM ( NOW() - dateEnded ) ) ) * 24 < 48
                                         ) d
                                     WHERE cume_dist < 0.50)
     )s
HAVING COUNT(*) > 5

IMHO COALESCE should not be use with AVG because it modifies the value. NULL means unknown and nothing else. It's not like using it in SUM. In this example, if we replace AVG by SUM, the result is not distorted. Adding 0 to a sum doesn't hurt anyone but calculating an average with 0 for the unknown values, you don't get the real average.

In that case, I would add price IS NOT NULL in WHERE clause to avoid these unknown values.

It doesn't - the C# compiler does :)

So this code:

string x = "hello";
string y = "there";
string z = "chaps";
string all = x + y + z;

actually gets compiled as:

string x = "hello";
string y = "there";
string z = "chaps";
string all = string.Concat(x, y, z);

(Gah - intervening edit removed other bits accidentally.)

The benefit of the C# compiler noticing that there are multiple string concatenations here is that you don't end up creating an intermediate string of x + y which then needs to be copied again as part of the concatenation of (x + y) and z. Instead, we get it all done in one go.

EDIT: Note that the compiler can't do anything if you concatenate in a loop. For example, this code:

string x = "";
foreach (string y in strings)
{
    x += y;
}

just ends up as equivalent to:

string x = "";
foreach (string y in strings)
{
    x = string.Concat(x, y);
}

... so this does generate a lot of garbage, and it's why you should use a StringBuilder for such cases. I have an article going into more details about the two which will hopefully answer further questions.

Either in your admin.py or in a separate forms.py you can add a ModelForm class and then declare your extra fields inside that as you normally would. I've also given an example of how you might use these values in form.save():

from django import forms
from yourapp.models import YourModel


class YourModelForm(forms.ModelForm):

    extra_field = forms.CharField()

    def save(self, commit=True):
        extra_field = self.cleaned_data.get('extra_field', None)
        # ...do something with extra_field here...
        return super(YourModelForm, self).save(commit=commit)

    class Meta:
        model = YourModel

To have the extra fields appearing in the admin just:

1. edit your admin.py and set the form property to refer to the form you created above
2. include your new fields in your fields or fieldsets declaration

Like this:

class YourModelAdmin(admin.ModelAdmin):

    form = YourModelForm

    fieldsets = (
        (None, {
            'fields': ('name', 'description', 'extra_field',),
        }),
    )

UPDATE: In django 1.8 you need to add fields = '__all__' to the metaclass of YourModelForm.

Another benefit of storing the images in the file system is that you don't have to do anything special to have the client cache them...

...unless of course the image isn't accessible via the document root (e.g. authentication barrier), in which case you'll need to check the cache-control headers your code is sending.

Accepted answer is outdated.

If you use MySQL 5.5.3+, use utf8mb4_unicode_ci instead of utf8_unicode_ci to ensure the characters typed by your users won't give you errors.

utf8mb4 supports emojis for example, whereas utf8 might give you hundreds of encoding-related bugs like:

Incorrect string value: ‘\xF0\x9F\x98\x81…’ for column ‘data’ at row 1

On Linux, you can use

date -d "-1 days" +"%a %d/%m/%Y"

In general, I use nohup CMD & to run a nohup background process. However, when the command is in a form that nohup won't accept then I run it through bash -c "...".

For example:

nohup bash -c "(time ./script arg1 arg2 > script.out) &> time_n_err.out" &

stdout from the script gets written to script.out, while stderr and the output of time goes into time_n_err.out.

So, in your case:

nohup bash -c "(time bash executeScript 1 input fileOutput > scrOutput) &> timeUse.txt" &

This also works:

zip(*elements)[1]

(I am mainly posting this, to prove to myself that I have groked zip...)

See it in action:

>>> help(zip)

Help on built-in function zip in module builtin:

zip(...)

zip(seq1 [, seq2 [...]]) -> [(seq1[0], seq2[0] ...), (...)]

Return a list of tuples, where each tuple contains the i-th element from each of the argument sequences. The returned list is truncated in length to the length of the shortest argument sequence.

>>> elements = [(1,1,1),(2,3,7),(3,5,10)]
>>> zip(*elements)
[(1, 2, 3), (1, 3, 5), (1, 7, 10)]
>>> zip(*elements)[1]
(1, 3, 5)
>>>

Neat thing I learned today: Use *list in arguments to create a parameter list for a function...

Note: In Python3, zip returns an iterator, so instead use list(zip(*elements)) to return a list of tuples.

For anyone who landed here with this error, like I did:

Unable to obtain LocalDateTime from TemporalAccessor: {HourOfAmPm=0, MinuteOfHour=0}

It came from a the following line:

LocalDateTime.parse(date, DateTimeFormatter.ofPattern("M/d/yy h:mm"));

It turned out that it was because I was using a 12hr Hour pattern on a 0 hour, instead of a 24hr pattern.

Changing the hour to 24hr pattern by using a capital H fixes it:

LocalDateTime.parse(date, DateTimeFormatter.ofPattern("M/d/yy H:mm"));

As you want to exclude both words, you need a conjuction:

^/(?!ignoreme$)(?!ignoreme2$)[a-z0-9]+$

Now both conditions must be true (neither ignoreme nor ignoreme2 is allowed) to have a match.

NumPy is not just more efficient; it is also more convenient. You get a lot of vector and matrix operations for free, which sometimes allow one to avoid unnecessary work. And they are also efficiently implemented.

For example, you could read your cube directly from a file into an array:

x = numpy.fromfile(file=open("data"), dtype=float).reshape((100, 100, 100))

Sum along the second dimension:

s = x.sum(axis=1)

Find which cells are above a threshold:

(x > 0.5).nonzero()

Remove every even-indexed slice along the third dimension:

x[:, :, ::2]

Also, many useful libraries work with NumPy arrays. For example, statistical analysis and visualization libraries.

Even if you don't have performance problems, learning NumPy is worth the effort.

Create a C# class that maps to your Json and use Newsoft JsonConvert to Deserialise it.

For example:

public Class MyResponse
{
    public Meta Meta { get; set; }
    public Response Response { get; set; }
}

The MODERN approach is to consider cases where column of information come from a web service such as an OData source. If you need to generate a filter select fields off of massive data that has replicated values for the column, consider the code below:

var CatalogURL = getweb(currenturl)
                 +"/_api/web/lists/getbytitle('Site%20Inventory%20and%20Assets')/items?$select=Expense_x005F_x0020_Type&$orderby=Expense_x005F_x0020_Type";

/* the column that is replicated, is ordered by <column_name> */

    OData.read(CatalogURL,
        function(data,request){

            var myhtml ="";
            var myValue ="";

            for(var i = 0; i < data.results.length; i++)
            {
                myValue = data.results[i].Expense_x005F_x0020_Type;

                if(i == 0)
                {
                        myhtml += "<option value='"+myValue+"'>"+myValue+"</option>";
                }
                else
                if(myValue != data.results[i-1].Expense_x005F_x0020_Type)
                {
                        myhtml += "<option value='"+myValue+"'>"+myValue+"</option>";

                }
                else
                {

                }


            }

            $("#mySelect1").append(myhtml);

        });

var slug = function(str) {
  str = str.replace(/^\s+|\s+$/g, ''); // trim
  str = str.toLowerCase();

  // remove accents, swap ñ for n, etc
  var from = "ãàáäâ?èéëêìíïîõòóöôùúüûñç·/_,:;";
  var to   = "aaaaaeeeeeiiiiooooouuuunc------";
  for (var i=0, l=from.length ; i<l ; i++) {
    str = str.replace(new RegExp(from.charAt(i), 'g'), to.charAt(i));
  }

  str = str.replace(/[^a-z0-9 -]/g, '') // remove invalid chars
    .replace(/\s+/g, '-') // collapse whitespace and replace by -
    .replace(/-+/g, '-'); // collapse dashes

  return str;
};

and try

slug($('#field').val())

That's a very complex question for a simple answer.

You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.

Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.

• https://api.coinsecure.in/v1
• https://api.coinsecure.in/v1/originalUI
• https://api.coinsecure.in/v1/slateUI#!/Blockchain_Tools/v1_bitcoin_search_txid

At the very top level I think quality REST API docs require at least the following:

• a list of all your API endpoints (base/relative URLs)
• corresponding HTTP GET/POST/... method type for each endpoint
• request/response MIME-type (how to encode params and parse replies)
• a sample request/response, including HTTP headers
• type and format specified for all params, including those in the URL, body and headers
• a brief text description and important notes
• a short code snippet showing the use of the endpoint in popular web programming languages

Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.

You need to consider that GROUP BY happens after the WHERE clause conditions have been evaluated. And the WHERE clause always considers only one row, meaning that in your query, the meta_key conditions will always prevent any records from being selected, since one column cannot have multiple values for one row.

And what about the redundant meta_value checks? If a value is allowed to be both smaller and greater than a given value, then its actual value doesn't matter at all - the check can be omitted.

According to one of your comments you want to check for places less than a certain distance from a given location. To get correct distances, you'd actually have to use some kind of proper distance function (see e.g. this question for details). But this SQL should give you an idea how to start:

SELECT items.* FROM items i, meta_data m1, meta_data m2
    WHERE i.item_id = m1.item_id and i.item_id = m2.item_id
    AND m1.meta_key = 'lat' AND m1.meta_value >= 55 AND m1.meta_value <= 65
    AND m2.meta_key = 'lng' AND m2.meta_value >= 20 AND m2.meta_value <= 30

The jquery form plugin offers an easy way to iterate over your form elements and put them in a query string. It might also be useful for whatever else you need to do with these values.

var queryString = $('#myFormId').formSerialize();

From http://malsup.com/jquery/form

Or using straight jquery:

var queryString = $('#myFormId').serialize();

There is also who is active?:

Who is Active? is a comprehensive server activity stored procedure based on the SQL Server 2005 and 2008 dynamic management views (DMVs). Think of it as sp_who2 on a hefty dose of anabolic steroids

Well, it's clearly not a number since it has dashes in it. The error message and the two comments tell you that it is a factor but the commentators are apparently waiting and letting the message sink in. Dirk is suggesting that you do this:

 EPL2011_12$Date2 <- as.Date( as.character(EPL2011_12$Date), "%d-%m-%y")

After that you can do this:

 EPL2011_12FirstHalf <- subset(EPL2011_12, Date2 > as.Date("2012-01-13") )

R date functions assume the format is either "YYYY-MM-DD" or "YYYY/MM/DD". You do need to compare like classes: date to date, or character to character.

Maven is packaged for Fedora since mid 2014, so it is now pretty easy. Just type

sudo dnf install maven

Now test the installation, just run maven in a random directory

mvn

And it will fail, because you did not specify a goal, e.g. mvn package

Basically, work is done only on non-leaf nodes while building a heap...and the work done is the amount of swapping down to satisfy heap condition...in other words (in worst case) the amount is proportional to the height of the node...all in all the complexity of the problem is proportional to the sum of heights of all the non-leaf nodes..which is (2^h+1 - 1)-h-1=n-h-1= O(n)

Got scared to see complex answers, being new to C#.

Here are some simple answers.
Merging d1, d2, and so on.. dictionaries and handle any overlapping keys ("b" in below examples):

Example 1

{
    // 2 dictionaries,  "b" key is common with different values

    var d1 = new Dictionary<string, int>() { { "a", 10 }, { "b", 21 } };
    var d2 = new Dictionary<string, int>() { { "c", 30 }, { "b", 22 } };

    var result1 = d1.Concat(d2).GroupBy(ele => ele.Key).ToDictionary(ele => ele.Key, ele => ele.First().Value);
    // result1 is  a=10, b=21, c=30    That is, took the "b" value of the first dictionary

    var result2 = d1.Concat(d2).GroupBy(ele => ele.Key).ToDictionary(ele => ele.Key, ele => ele.Last().Value);
    // result2 is  a=10, b=22, c=30    That is, took the "b" value of the last dictionary
}

Example 2

{
    // 3 dictionaries,  "b" key is common with different values

    var d1 = new Dictionary<string, int>() { { "a", 10 }, { "b", 21 } };
    var d2 = new Dictionary<string, int>() { { "c", 30 }, { "b", 22 } };
    var d3 = new Dictionary<string, int>() { { "d", 40 }, { "b", 23 } };

    var result1 = d1.Concat(d2).Concat(d3).GroupBy(ele => ele.Key).ToDictionary(ele => ele.Key, ele => ele.First().Value);
    // result1 is  a=10, b=21, c=30, d=40    That is, took the "b" value of the first dictionary

    var result2 = d1.Concat(d2).Concat(d3).GroupBy(ele => ele.Key).ToDictionary(ele => ele.Key, ele => ele.Last().Value);
    // result2 is  a=10, b=23, c=30, d=40    That is, took the "b" value of the last dictionary
}

For more complex scenarios, see other answers.
Hope that helped.

If you need to display all the records after 2014-09-01, add this to your query:

SELECT * FROM Events
WHERE Format(Events.DATE_TIME,'yyyy-MM-dd hh:mm:ss')  >= Format("2014-09-01 00:00:00","yyyy-MM-dd hh:mm:ss")

"mondate" is somewhat similar to "Date" except that adding n adds n months rather than n days:

> library(mondate)
> d <- as.Date("2004-01-31")
> as.mondate(d) + 1
mondate: timeunits="months"
[1] 2004-02-29

try this:

<a id="send-thoughts" href="">Click</a>
<textarea id="message"></textarea>
<!--<textarea id="#message"></textarea>-->

            jQuery("a#send-thoughts").click(function() {
                //var thought = jQuery("textarea#message").val();
                var thought = $("#message").val();
                alert(thought);
            });

Allen Holub's "Enough Rope to Shoot Yourself in the Foot" lists the following 2 rules:

120. Reference arguments should always be `const`
121. Never use references as outputs, use pointers

He lists several reasons why references were added to C++:

• they are necessary to define copy constructors
• they are necessary for operator overloads
• const references allow you to have pass-by-value semantics while avoiding a copy

His main point is that references should not be used as 'output' parameters because at the call site there's no indication of whether the parameter is a reference or a value parameter. So his rule is to only use const references as arguments.

Personally, I think this is a good rule of thumb as it makes it more clear when a parameter is an output parameter or not. However, while I personally agree with this in general, I do allow myself to be swayed by the opinions of others on my team if they argue for output parameters as references (some developers like them immensely).

Add android:screenOrientation="portrait" in AndroidManifest.xml file.

For example :

<activity android:name=".MapScreen" 
 android:screenOrientation="portrait"></activity>

If we have one table like that

mysql> select * from user_mail;
+------------+-------+
| email      | user | 
+------------+-------+-
| email1@gmail |     1 | 
| email2@gmail |     2 |
+------------+-------+--------+------------+

and the array table:

mysql> select * from user_mail_array;
+------------+-------+-------------+
| email      | user | preferences |
+------------+-------+-------------+
| email1@gmail |     1 |           1 |
| email1@gmail |     1 |           2 |
| email1@gmail |     1 |           3 |
| email1@gmail |     1 |           4 |
| email2@gmail |     2 |           5 |
| email2@gmail |     2 |           6 |

We can select the rows of the second table as one array with CONCAT function:

mysql> SELECT t1.*, GROUP_CONCAT(t2.preferences) AS preferences
     FROM user_mail t1,user_mail_array t2
       where t1.email=t2.email and t1.user=t2.user
     GROUP BY t1.email,t1.user;

+------------+-------+--------+------------+-------------+
| email      | user | preferences |
+------------+-------+--------+------------+-------------+
|email1@gmail |     1 | 1,3,2,4     |
|email2@gmail |     2 | 5,6         |
+------------+-------+--------+------------+-------------+

Using base graphics, we can use at = to control box position , combined with boxwex = for the width of the boxes. The 1st boxplot statement creates a blank plot. Then add the 2 traces in the following two statements.

Note that in the following, we use df[,-1] to exclude the 1st (id) column from the values to plot. With different data frames, it may be necessary to change this to subset for whichever columns contain the data you want to plot.

boxplot(df[,-1], boxfill = NA, border = NA) #invisible boxes - only axes and plot area
boxplot(df[df$id=="Good", -1], xaxt = "n", add = TRUE, boxfill="red", 
  boxwex=0.25, at = 1:ncol(df[,-1]) - 0.15) #shift these left by -0.15
boxplot(df[df$id=="Bad", -1], xaxt = "n", add = TRUE, boxfill="blue", 
  boxwex=0.25, at = 1:ncol(df[,-1]) + 0.15) #shift to the right by +0.15

Some dummy data:

df <- data.frame(
  id = c(rep("Good",200), rep("Bad", 200)),
  F1 = c(rnorm(200,10,2), rnorm(200,8,1)),
  F2 = c(rnorm(200,7,1),  rnorm(200,6,1)),
  F3 = c(rnorm(200,6,2),  rnorm(200,9,3)),
  F4 = c(rnorm(200,12,3), rnorm(200,8,2)))

Either:

1. with row.name inside the apply(..., axis=1) call:

df = pandas.DataFrame([[1,2,3],[4,5,6]], columns=['a','b','c'], index=['x','y'])

   a  b  c
x  1  2  3
y  4  5  6

df.apply(lambda row: row.name, axis=1)

x    x
y    y

2. with iterrows() (slower)

DataFrame.iterrows() allows you to iterate over rows, and access their index:

for idx, row in df.iterrows():
    ...

I was looking for solution for exactly the same problem. To remove all classes starting with prefix "fontid_" After reading this article I wrote a small plugin which I'm using now.

(function ($) {
        $.fn.removePrefixedClasses = function (prefix) {
            var classNames = $(this).attr('class').split(' '),
                className,
                newClassNames = [],
                i;
            //loop class names
            for(i = 0; i < classNames.length; i++) {
                className = classNames[i];
                // if prefix not found at the beggining of class name
                if(className.indexOf(prefix) !== 0) {
                    newClassNames.push(className);
                    continue;
                }
            }
            // write new list excluding filtered classNames
            $(this).attr('class', newClassNames.join(' '));
        };
    }(fQuery));

Usage:

$('#elementId').removePrefixedClasses('prefix-of-classes_');

for classes you can use:

div[class^="jander"]

You need to escape ", so it won't be interpreted as end of string. Use \ to escape it:

echo "<script>$('#edit_errors').html('<h3><em><font color=\"red\">Please Correct Errors Before Proceeding</font></em></h3>')</script>";

Add this one to your html if you only have access to the html:

<link href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css" rel="stylesheet">

I use this script to quickly find files across directories in a project. I have found it works great and takes advantage of Vim's autocomplete by opening up and closing an new buffer for the search. It also smartly completes as much as possible for you so you can usually just type a character or two and open the file across any directory in your project. I started using it specifically because of a Java project and it has saved me a lot of time. You just build the cache once when you start your editing session by typing :FC (directory names). You can also just use . to get the current directory and all subdirectories. After that you just type :FF (or FS to open up a new split) and it will open up a new buffer to select the file you want. After you select the file the temp buffer closes and you are inside the requested file and can start editing. In addition, here is another link on Stack Overflow that may help.

You can achieve that using a mix of peek(..) and anyMatch(..).

Using your example:

someObjects.stream().peek(obj -> {
   <your code here>
}).anyMatch(obj -> !<some_condition_met>);

Or just write a generic util method:

public static <T> void streamWhile(Stream<T> stream, Predicate<? super T> predicate, Consumer<? super T> consumer) {
    stream.peek(consumer).anyMatch(predicate.negate());
}

And then use it, like this:

streamWhile(someObjects.stream(), obj -> <some_condition_met>, obj -> {
   <your code here>
});

This is a clarification because I have seen things done in code which are honestly confusing - I think the following example might assist others.

As others have said before - Bitmap inherits from the Abstract Image class

Abstract effectively means you cannot create a New() instance of it.

    Image imgBad1 = new Image();        // Bad - won't compile
    Image imgBad2 = new Image(200,200); // Bad - won't compile

But you can do the following:

    Image imgGood;  // Not instantiated object!
    // Now you can do this
    imgGood = new Bitmap(200, 200);

You can now use imgGood as you would the same bitmap object if you had done the following:

    Bitmap bmpGood = new Bitmap(200,200);

The nice thing here is you can draw the imgGood object using a Graphics object

    Graphics gr = default(Graphics);
    gr = Graphics.FromImage(new Bitmap(1000, 1000));
    Rectangle rect = new Rectangle(50, 50, imgGood.Width, imgGood.Height); // where to draw
    gr.DrawImage(imgGood, rect);

Here imgGood can be any Image object - Bitmap, Metafile, or anything else that inherits from Image!

First, thanks to William.

Second - i needed a dynamic version. And it works!

An example:

CSS:

p[id^="detailView-"]
{
    display: none;
}

p[id^="detailView-"]:target
{
    display: block;
}

HTML:

<a href="#detailView-1">Show View1</a>
<p id="detailView-1">View1</p>

<a href="#detailView-2">Show View2</a>
<p id="detailView-2">View2</p>

I'm familiar with this problem. The simplest workaround is to conditionally repeat the operation. I've never seen it fail twice in a row - unless there actually is an open file or a permissions issue, obviously!

rd /s /q c:\deleteme
if exist c:\deleteme rd /s /q c:\deleteme

The pythonic way would be:

mystring = 'Hello World, this should work!'
find_all = lambda c,s: [x for x in range(c.find(s), len(c)) if c[x] == s]

# s represents the search string
# c represents the character string

find_all(mystring,'o')    # will return all positions of 'o'

In Swift 3.0, Use

let color = UIColor.lightText
textField.attributedPlaceholder = NSAttributedString(string: textField.placeholder, attributes: [NSForegroundColorAttributeName : color])

In Siwft 5.0 + Use

let color = UIColor.lightText
let placeholder = textField.placeholder ?? "" //There should be a placeholder set in storyboard or elsewhere string or pass empty
textField.attributedPlaceholder = NSAttributedString(string: placeholder, attributes: [NSAttributedString.Key.foregroundColor : color])

A nice tip is to just navigate to your desired start folder in Windows Explorer:

• click File
• click Open command prompt
• then just type "jupyter notebook" and press enter

a web browser should pop up shortly with the correct start folder.

Surprisingly, all other answers only say half the truth or are actually wrong!

• e.stopImmediatePropagation() stops any further handler from being called for this event, no exceptions
• e.stopPropagation() is similar, but does still call all handlers for this phase on this element if not called already

What phase?

E.g. a click event will always first go all the way down the DOM (called “capture phase”), finally reach the origin of the event (“target phase”) and then bubble up again (“bubble phase”). And with addEventListener() you can register multiple handlers for both capture and bubble phase independently. (Target phase calls handlers of both types on the target without distinguishing.)

And this is what the other answers are incorrect about:

http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#intern()

Basically doing String.intern() on a series of strings will ensure that all strings having same contents share same memory. So if you have list of names where 'john' appears 1000 times, by interning you ensure only one 'john' is actually allocated memory.

This can be useful to reduce memory requirements of your program. But be aware that the cache is maintained by JVM in permanent memory pool which is usually limited in size compared to heap so you should not use intern if you don't have too many duplicate values.

More on memory constraints of using intern()

On one hand, it is true that you can remove String duplicates by internalizing them. The problem is that the internalized strings go to the Permanent Generation, which is an area of the JVM that is reserved for non-user objects, like Classes, Methods and other internal JVM objects. The size of this area is limited, and is usually much smaller than the heap. Calling intern() on a String has the effect of moving it out from the heap into the permanent generation, and you risk running out of PermGen space.

-- From: http://www.codeinstructions.com/2009/01/busting-javalangstringintern-myths.html

From JDK 7 (I mean in HotSpot), something has changed.

In JDK 7, interned strings are no longer allocated in the permanent generation of the Java heap, but are instead allocated in the main part of the Java heap (known as the young and old generations), along with the other objects created by the application. This change will result in more data residing in the main Java heap, and less data in the permanent generation, and thus may require heap sizes to be adjusted. Most applications will see only relatively small differences in heap usage due to this change, but larger applications that load many classes or make heavy use of the String.intern() method will see more significant differences.

-- From Java SE 7 Features and Enhancements

Update: Interned strings are stored in main heap from Java 7 onwards. http://www.oracle.com/technetwork/java/javase/jdk7-relnotes-418459.html#jdk7changes

You will need to define "special characters", but it's likely that for some string s you mean:

import re
if re.match(r'^\w+$', s):
    # s is good-to-go

They are extension methods. Welcome to a whole new fluent world. :)

Per the Javadoc:

Returns the value of a request parameter as a String, or null if the parameter does not exist.

Do note that it is possible to submit an empty parameter - such that the parameter exists, but has no value. For example, I could include &log=&somethingElse into the URL to enable logging, without needing to specify &log=true. In this case, the value will be an empty String ("").

All(RDD, DataFrame, and DataSet) in one picture.

RDD

RDD is a fault-tolerant collection of elements that can be operated on in parallel.

DataFrame

DataFrame is a Dataset organised into named columns. It is conceptually equivalent to a table in a relational database or a data frame in R/Python, but with richer optimisations under the hood.

Dataset

Dataset is a distributed collection of data. Dataset is a new interface added in Spark 1.6 that provides the benefits of RDDs (strong typing, ability to use powerful lambda functions) with the benefits of Spark SQL’s optimized execution engine.

---

Note:

Dataset of Rows (Dataset[Row]) in Scala/Java will often refer as DataFrames.

Nice comparison of all of them with a code snippet.

Q: Can you convert one to the other like RDD to DataFrame or vice-versa?

Yes, both are possible

1. RDD to DataFrame with .toDF()

val rowsRdd: RDD[Row] = sc.parallelize(
  Seq(
    Row("first", 2.0, 7.0),
    Row("second", 3.5, 2.5),
    Row("third", 7.0, 5.9)
  )
)

val df = spark.createDataFrame(rowsRdd).toDF("id", "val1", "val2")

df.show()
+------+----+----+
|    id|val1|val2|
+------+----+----+
| first| 2.0| 7.0|
|second| 3.5| 2.5|
| third| 7.0| 5.9|
+------+----+----+

more ways: Convert an RDD object to Dataframe in Spark

2. DataFrame/DataSet to RDD with .rdd() method

val rowsRdd: RDD[Row] = df.rdd() // DataFrame to RDD

Use component scanning as given below, if com.project.action.PasswordHintAction is annotated with stereotype annotations

<context:component-scan base-package="com.project.action"/>

EDIT

I see your problem, in PasswordHintActionTest you are autowiring PasswordHintAction. But you did not create bean configuration for PasswordHintAction to autowire. Add one of stereotype annotation(@Component, @Service, @Controller) to PasswordHintAction like

@Component
public class PasswordHintAction extends BaseAction {
    private static final long serialVersionUID = -4037514607101222025L;
    private String username;

or create xml configuration in applicationcontext.xml like

<bean id="passwordHintAction" class="com.project.action.PasswordHintAction" />

Java does not have a datatype for unsigned integers.

You can define a long instead of an int if you need to store large values.

You can also use a signed integer as if it were unsigned. The benefit of two's complement representation is that most operations (such as addition, subtraction, multiplication, and left shift) are identical on a binary level for signed and unsigned integers. A few operations (division, right shift, comparison, and casting), however, are different. As of Java SE 8, new methods in the Integer class allow you to fully use the int data type to perform unsigned arithmetic:

In Java SE 8 and later, you can use the int data type to represent an unsigned 32-bit integer, which has a minimum value of 0 and a maximum value of 2^32-1. Use the Integer class to use int data type as an unsigned integer. Static methods like compareUnsigned, divideUnsigned etc have been added to the Integer class to support the arithmetic operations for unsigned integers.

Note that int variables are still signed when declared but unsigned arithmetic is now possible by using those methods in the Integer class.

If your selected elements are not one, you need use this way:

$('[type="date"]').datepicker();
$('[type="date"]').change(function() {
    var date = $(this).datepicker("getDate");
    console.log(date);
});

From the description and from the reference to the search box in the Ubuntu site, I gather that you actually want an arrowhead character pointing to the right. There are no Unicode characters designed to be used as arrowheads, but some of them may visually resemble an arrowhead.

In particular, if you draw your idea of the character at Shapecatcher.com, you will find many suggestions, such as “>” RIGHT-POINTING ANGLE BRACKET' (U+232A) and “?” MEDIUM RIGHT-POINTING ANGLE BRACKET ORNAMENT (U+276D).

Such characters generally have limited support in fonts, so you would need to carefully write a longish font-family list or to use a downloadable font. See my Guide to using special characters in HTML.

Especially if the intended use is as a symbol in a search box, as the reference to the Ubuntu page suggests, it is questionable whether you should use a character at all. It’s not really an element of text here; rather, a graphic symbol that accompanies text but isn’t a part of it. So why take all the trouble with using a character (safely), when it isn’t really a character?

I am using this on PHP 7.2.x, it's working fine for me:

public function make_hash($userStr){
        try{
            /** 
             * Used and tested on PHP 7.2x, Salt has been removed manually, it is now added by PHP 
             */
             return password_hash($userStr, PASSWORD_BCRYPT);
            }catch(Exception $exc){
                $this->tempVar = $exc->getMessage();
                return false;
            }
        }

and then authenticate the hash with the following function:

public function varify_user($userStr,$hash){
        try{
            if (password_verify($userStr, $hash)) {
                 return true;
                }
            else {
                return false;
                }
            }catch(Exception $exc){
                $this->tempVar = $exc->getMessage();
                return false;
            }
        }

Example:

  //create hash from user string

 $user_password = $obj->make_hash2($user_key);

and to authenticate this hash use the following code:

if($obj->varify_user($key, $user_key)){
      //this is correct, you can proceed with  
    }

That's all.

AffineTransformOp offers the additional flexibility of choosing the interpolation type.

BufferedImage before = getBufferedImage(encoded);
int w = before.getWidth();
int h = before.getHeight();
BufferedImage after = new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB);
AffineTransform at = new AffineTransform();
at.scale(2.0, 2.0);
AffineTransformOp scaleOp = 
   new AffineTransformOp(at, AffineTransformOp.TYPE_BILINEAR);
after = scaleOp.filter(before, after);

The fragment shown illustrates resampling, not cropping; this related answer addresses the issue; some related examples are examined here.

Taking a guess at what it is you're asking for. I'm assuming by millisecond frame timer you're looking for something that acts like the following,

double mticks()
{
    struct timeval tv;
    gettimeofday(&tv, 0);
    return (double) tv.tv_usec / 1000 + tv.tv_sec * 1000;
}

but uses std::chrono instead,

double mticks()
{
    typedef std::chrono::high_resolution_clock clock;
    typedef std::chrono::duration<float, std::milli> duration;

    static clock::time_point start = clock::now();
    duration elapsed = clock::now() - start;
    return elapsed.count();
}

Hope this helps.

Here is my solution, but in python (I tried and failed to find any post on the topic related to python):

# modify table for legacy version which did not have leave type and leave time columns of rings3 table.
sql = 'PRAGMA table_info(rings3)' # get table info. returns an array of columns.
result = inquire (sql) # call homemade function to execute the inquiry
if len(result)<= 6: # if there are not enough columns add the leave type and leave time columns
    sql = 'ALTER table rings3 ADD COLUMN leave_type varchar'
    commit(sql) # call homemade function to execute sql
    sql = 'ALTER table rings3 ADD COLUMN leave_time varchar'
    commit(sql)

I used PRAGMA to get the table information. It returns a multidimensional array full of information about columns - one array per column. I count the number of arrays to get the number of columns. If there are not enough columns, then I add the columns using the ALTER TABLE command.

As others point out, the user name is usually anonymous, and the password is usually your e-mail address, but this is not universally true, and has been found not to work for certain anonymous FTP sites. For example, at least some cPanel sites seem to deviate from the norm, and if given the traditional user name without domain, one of various errors may result:

If the server uses Pure-FTP as the FTP server:

421 Can't change directory to /var/ftp/ error message.

If the server uses ProFTP as the FTP server:

530 Login Authentication Failed error message.

When one of the aforementioned errors occurs when attempting anonymous access, try including a domain with the username. For example, where example.com is the domain used in your e-mail address:

User name: [email protected]

In the specific case of a cPanel site, the password value is unimportant, and may be left blank, but there is no harm in providing a "traditional" anonymous password formatted as an e-mail address.

For reference, this answer is based on content found on a documentation.cpanel.net Anonymous FTP page. At the time of this writing, it stated:

When users log in to FTP anonymously, they must format usernames as [email protected], where example.com represents the user's domain name. This requirement directs your server to the correct public_ftp directory.

Try this

$window.location.href="#page-name";
$window.location.reload();

I think that you'll probably have to use $.ajax() if you want to change the encoding, see the contentType param below (the success and error callbacks assume you have <div id="success"></div> and <div id="error"></div> in the html):

$.ajax({
    type: "POST",
    url: "SomePage.aspx/GetSomeObjects",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    data: "{id: '" + someId + "'}",
    success: function(json) {
        $("#success").html("json.length=" + json.length);
        itemAddCallback(json);
    },
    error: function (xhr, textStatus, errorThrown) {
        $("#error").html(xhr.responseText);
    }
});

I actually just had to do this about an hour ago, what a coincidence!

I found a JS range function equivalent to the one in PHP, and works amazingly great here. Works forward & backward, and works with integers, floats and alphabets!

function range(low, high, step) {
  //  discuss at: http://phpjs.org/functions/range/
  // original by: Waldo Malqui Silva
  //   example 1: range ( 0, 12 );
  //   returns 1: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
  //   example 2: range( 0, 100, 10 );
  //   returns 2: [0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100]
  //   example 3: range( 'a', 'i' );
  //   returns 3: ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i']
  //   example 4: range( 'c', 'a' );
  //   returns 4: ['c', 'b', 'a']

  var matrix = [];
  var inival, endval, plus;
  var walker = step || 1;
  var chars = false;

  if (!isNaN(low) && !isNaN(high)) {
    inival = low;
    endval = high;
  } else if (isNaN(low) && isNaN(high)) {
    chars = true;
    inival = low.charCodeAt(0);
    endval = high.charCodeAt(0);
  } else {
    inival = (isNaN(low) ? 0 : low);
    endval = (isNaN(high) ? 0 : high);
  }

  plus = ((inival > endval) ? false : true);
  if (plus) {
    while (inival <= endval) {
      matrix.push(((chars) ? String.fromCharCode(inival) : inival));
      inival += walker;
    }
  } else {
    while (inival >= endval) {
      matrix.push(((chars) ? String.fromCharCode(inival) : inival));
      inival -= walker;
    }
  }

  return matrix;
}

And here is the minified version:

function range(h,c,b){var i=[];var d,f,e;var a=b||1;var g=false;if(!isNaN(h)&&!isNaN(c)){d=h;f=c}else{if(isNaN(h)&&isNaN(c)){g=true;d=h.charCodeAt(0);f=c.charCodeAt(0)}else{d=(isNaN(h)?0:h);f=(isNaN(c)?0:c)}}e=((d>f)?false:true);if(e){while(d<=f){i.push(((g)?String.fromCharCode(d):d));d+=a}}else{while(d>=f){i.push(((g)?String.fromCharCode(d):d));d-=a}}return i};

Try this it works for me,

<style>_x000D_
    select{_x000D_
        border: 0 !important;  /*Removes border*/_x000D_
        -webkit-appearance: none;_x000D_
        -moz-appearance: none;_x000D_
        appearance: none;_x000D_
        text-overflow:'';_x000D_
        text-indent: 0.01px; /* Removes default arrow from firefox*/_x000D_
        text-overflow: "";  /*Removes default arrow from firefox*/_x000D_
    }_x000D_
    select::-ms-expand {_x000D_
        display: none;_x000D_
    }_x000D_
    .select-wrapper_x000D_
    {_x000D_
        padding-left:0px;_x000D_
        overflow:hidden;_x000D_
    }_x000D_
</style>_x000D_
    _x000D_
<div class="select-wrapper">_x000D_
     <select> ... </select>_x000D_
</div>

You can not hide but using overflow hidden you can actually make it disappear.

The right mental model for using mutexes: The mutex protects an invariant.

Why are you sure that this is really right mental model for using mutexes? I think right model is protecting data but not invariants.

The problem of protecting invariants presents even in single-threaded applications and has nothing common with multi-threading and mutexes.

Furthermore, if you need to protect invariants, you still may use binary semaphore wich is never recursive.

you can use the below css styles for all browsers except Firefox 30

select {
  background: url(dropdown_arw.png) no-repeat right center;
  appearance: none;
  -moz-appearance: none;
  -webkit-appearance: none;
  width: 90px;
  text-indent: 0.01px;
  text-overflow: "";
}

If you're testing this in IE, dominant-baseline and alignment-baseline are not supported.

The most effective way to center text in IE is to use something like this with "dy":

<text font-size="ANY SIZE" text-anchor="middle" "dy"="-.4em"> Ya Text </text>

The negative value will shift it up and a positive value of dy will shift it down. I've found using -.4em seems a bit more centered vertically to me than -.5em, but you'll be the judge of that.

Define a const static instance of the struct with the initial values and then simply assign this value to your variable whenever you want to reset it.

For example:

static const struct x EmptyStruct;

Here I am relying on static initialization to set my initial values, but you could use a struct initializer if you want different initial values.

Then, each time round the loop you can write:

myStructVariable = EmptyStruct;

The trick is to

1. create a CNAME for www.myapp.com to myapp.heroku.com
2. create a 301 redirection from myapp.com to www.myapp.com

If you want to remove /category/ from the url, follow these two steps:

1. Go to Settings >> Permalinks and select Custom and enter: /%category%/%postname%/
2. Next set your Category Base to .

Save it and you’ll see your URL changed to this format: http://yourblog.com/quotes/

Try this one, it gives a unique hard disk ID: Port of DiskId32 for Delphi 7-2010.

Expanding a bit on @Eruant's answer,

$(window).on('load', function() {
    // your code here
});

Works very well with both async and defer while loading on scripts.

So you can import all scripts like this:

<script src="/js/script1.js" async defer></script>
<script src="/js/script2.js" async defer></script>
<script src="/js/script3.js" async defer></script>

Just make sure script1 doesn't call functions from script3 before $(window).on('load' ..., make sure to call them inside window load event.

More about async/defer here.

Correction to top query above, to allow to run from any database

SELECT COUNT(COLUMN_NAME) FROM [*database*].INFORMATION_SCHEMA.COLUMNS WHERE 
TABLE_CATALOG = 'database' AND TABLE_SCHEMA = 'dbo'
AND TABLE_NAME = 'table'

array2 = array1;

is not supported in c. You have to use functions like strcpy() to do it.

By default, Maven will always look in the official Maven repository, which is http://repo1.maven.org.

When Maven tries to build a project, it will look in your local repository (by default ~/.m2/repository but you can configure it by changing the <localRepository> value in your ~/.m2/settings.xml) to find any dependency, plugin or report defined in your pom.xml. If the adequate artifact is not found in your local repository, it will look in all external repositories configured, starting with the default one, http://repo1.maven.org.

You can configure Maven to avoid this default repository by setting a mirror in your settings.xml file:

<mirrors>
    <mirror>
        <id>repoMirror</id>
        <name>Our mirror for Maven repository</name>
        <url>http://the/server/</url>
        <mirrorOf>*</mirrorOf>
    </mirror>
</mirrors>

This way, instead of contacting http://repo1.maven.org, Maven will contact your entreprise repository (http://the/server in this example).

If you want to add another repository, you can define a new one in your settings.xml file:

<profiles>
    <profile>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <repositories>
            <repository>
                <id>foo.bar</id>
                <releases>
                    <enabled>true</enabled>
                </releases>
                <snapshots>
                    <enabled>true</enabled>
                </snapshots>
                <url>http://new/repository/server</url>
            </repository>
        </repositories>

You can see the complete settings.xml model here.

Concerning the clean process, you can ask Maven to run it offline. In this case, Maven will not try to reach any external repositories:

mvn -o clean 

strstr(request, "favicon") != NULL

I can not see where do you declare context. For the purpose of the intent creation you can use MainActivity.this

 lv.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                    long id) {
                Intent intent = new Intent(MainActivity.this, SendMessage.class);
                String message = "abc";
                intent.putExtra(EXTRA_MESSAGE, message);
                startActivity(intent);
            }
        });

To retrieve the object upon you have clicked you can use the AdapterView:

ListEntry entry = (ListEntry) parent.getItemAtPosition(position);

  final SurfaceView surf = (SurfaceView)findViewById(R.id.surface_home);
                surf.setOnTouchListener( new SurfaceView.OnTouchListener(){
                    private boolean moving = false;//stupid state
                    public boolean onTouch(View v, MotionEvent event) {
                        switch( event.getAction() ){
                        case MotionEvent.ACTION_DOWN:
                            final int x = (int)event.getX();
                            final int y = (int)event.getY();
                            final Rect bounds = mTiles.getBounds();
                            moving = bounds.intersects(x, y, x+1, y+1);
                            return true;
                        case MotionEvent.ACTION_MOVE:
                            if( moving ){
                                final int x_new = (int)event.getX();
                                final int y_new = (int)event.getY();
                                mDrawTiles.draw( new DrawLogic(){
                                    public void draw(Rect _surface) {
                                        mTiles.setBounds(
                                            x_new - mDrawWidth/2,
                                            y_new - mDrawHeight/2,
                                            x_new + mDrawWidth/2,
                                            y_new + mDrawHeight/2);
                                        }
                                    });

for Google Maps v3, you need to trigger the resize event differently:

google.maps.event.trigger(map, "resize");

See the documentation for the resize event (you'll need to search for the word 'resize'): http://code.google.com/apis/maps/documentation/v3/reference.html#event

Update

This answer has been here a long time, so a little demo might be worthwhile & although it uses jQuery, there's no real need to do so.

$(function() {
  var mapOptions = {
    zoom: 8,
    center: new google.maps.LatLng(-34.397, 150.644)

UPDATE 2018-05-22

With a new renderer release in version 3.32 of Maps JavaScript API the resize event is no longer a part of Map class.

The documentation states

When the map is resized, the map center is fixed

• The full-screen control now preserves center.

• There is no longer any need to trigger the resize event manually.

source: https://developers.google.com/maps/documentation/javascript/new-renderer

google.maps.event.trigger(map, "resize"); doesn't have any effect starting from version 3.32

The best solution for this problem is just open your mysql configuration directive file my.ini present inside the folder C:\xampp\mysql\bin and change the information related to the ports, usually some programs occupy the port no. 3306 as a result of that it stops working, Now you follow two steps to make it working.

enter code here

    Step-1. Search for ['client'],  you can see some thing like this

            [client] 
            # password       = your_password 
            port            = 3306
            socket          = "C:/xampp/mysql/mysql.sock"
 Now in the port section remove 3306 and add port = 3306 > 3307 as shown   below.

            [client] 
            # password       = your_password 
            port            = 3306 > 3307
            socket          = "C:/xampp/mysql/mysql.sock"


    Step -2. Similarly Search for  ['mysqld'], you can see something like this 

            [mysqld]
            port= 3306
            socket = "C:/xampp/mysql/mysql.sock"
            basedir = "C:/xampp/mysql" 
            tmpdir = "C:/xampp/tmp" 
            datadir = "C:/xampp/mysql/data"
            pid_file = "mysql.pid"
            # enable-named-pipe
            key_buffer = 16M
            max_allowed_packet = 1M
            sort_buffer_size = 512K
            net_buffer_length = 8K
            read_buffer_size = 256K
            read_rnd_buffer_size = 512K
            myisam_sort_buffer_size = 8M
            log_error = "mysql_error.log"


            Now here change the port number 3306 to 3307 and add a line "innodb_force_recovery = 1" exactly as shown below.


            [mysqld]
            port= 3307
            socket = "C:/xampp/mysql/mysql.sock"
            basedir = "C:/xampp/mysql" 
            tmpdir = "C:/xampp/tmp" 
            datadir = "C:/xampp/mysql/data"
            pid_file = "mysql.pid"
            # enable-named-pipe
            key_buffer = 16M
            max_allowed_packet = 1M
            sort_buffer_size = 512K
            net_buffer_length = 8K
            read_buffer_size = 256K
            read_rnd_buffer_size = 512K
            myisam_sort_buffer_size = 8M
            log_error = "mysql_error.log"
            innodb_force_recovery = 1

Thats it, restart you mysql service, it will work for sure.

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

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

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

just create new android project and copy paste my code and have fun! :) also remember in xml i have image view and his background images replace with yout own images thanks..

You can use jquery for this:

$('body').bind('copy paste',function(e) {
    e.preventDefault(); return false; 
});

Using jQuery bind() and specififying your desired eventTypes .

There is not only 1 %SystemRoot%\System32 on Windows x64. There are 2 such directories.

The real %SystemRoot%\System32 directory is for 64-bit applications. This directory contains a 64-bit cmd.exe.

But there is also %SystemRoot%\SysWOW64 for 32-bit applications. This directory is used if a 32-bit application accesses %SystemRoot%\System32. It contains a 32-bit cmd.exe.

32-bit applications can access %SystemRoot%\System32 for 64-bit applications by using the alias %SystemRoot%\Sysnative in path.

For more details see the Microsoft documentation about File System Redirector.

So the subdirectory run was created either in %SystemRoot%\System32 for 64-bit applications and 32-bit cmd is run for which this directory does not exist because there is no subdirectory run in %SystemRoot%\SysWOW64 which is %SystemRoot%\System32 for 32-bit cmd.exe or the subdirectory run was created in %SystemRoot%\System32 for 32-bit applications and 64-bit cmd is run for which this directory does not exist because there is no subdirectory run in %SystemRoot%\System32 as this subdirectory exists only in %SystemRoot%\SysWOW64.

The following code could be used at top of the batch file in case of subdirectory run is in %SystemRoot%\System32 for 64-bit applications:

@echo off
set "SystemPath=%SystemRoot%\System32"
if not "%ProgramFiles(x86)%" == "" if exist %SystemRoot%\Sysnative\* set "SystemPath=%SystemRoot%\Sysnative"

Every console application in System32\run directory must be executed with %SystemPath% in the batch file, for example %SystemPath%\run\YourApp.exe.

How it works?

There is no environment variable ProgramFiles(x86) on Windows x86 and therefore there is really only one %SystemRoot%\System32 as defined at top.

But there is defined the environment variable ProgramFiles(x86) with a value on Windows x64. So it is additionally checked on Windows x64 if there are files in %SystemRoot%\Sysnative. In this case the batch file is processed currently by 32-bit cmd.exe and only in this case %SystemRoot%\Sysnative needs to be used at all. Otherwise %SystemRoot%\System32 can be used also on Windows x64 as when the batch file is processed by 64-bit cmd.exe, this is the directory containing the 64-bit console applications (and the subdirectory run).

Note: %SystemRoot%\Sysnative is not a directory! It is not possible to cd to %SystemRoot%\Sysnative or use if exist %SystemRoot%\Sysnative or if exist %SystemRoot%\Sysnative\. It is a special alias existing only for 32-bit executables and therefore it is necessary to check if one or more files exist on using this path by using if exist %SystemRoot%\Sysnative\cmd.exe or more general if exist %SystemRoot%\Sysnative\*.

Neither the hack nor the cleaner version work for Indigo. The hack is ignored, and the required configuration options are missing. For no apparent reason, build started working after not working and not providing any useful reason why. At least from the command line, I get reproducible results.

I also had added on or extended additional columns into my AspNetUsers table. When I wanted to simply view this data I found many examples like the code above with "Extensions" etc... This really amazed me that you had to write all those lines of code just to get a couple values from the current users.

It turns out that you can query the AspNetUsers table like any other table:

 ApplicationDbContext db = new ApplicationDbContext();
 var user = db.Users.Where(x => x.UserName == User.Identity.Name).FirstOrDefault();

Another option is to use querySelector('.foo') or querySelectorAll('.foo') which have broader browser support than getElementsByClassName.

To create an empty Array of Strings in Kotlin you should use one of the following six approaches:

First approach:

val empty = arrayOf<String>()

Second approach:

val empty = arrayOf("","","")

Third approach:

val empty = Array<String?>(3) { null }

Fourth approach:

val empty = arrayOfNulls<String>(3)

Fifth approach:

val empty = Array<String>(3) { "it = $it" }

Sixth approach:

val empty = Array<String>(0, { _ -> "" })

This was what I was looking for:

# Get the latest from GitHub, public repo:
$ npm install username/my-new-project --save-dev
# Bitbucket, private repo:
$ npm install git+https://token:[email protected]/username/my-new-project.git#master
$ npm install git+ssh://[email protected]/username/my-new-project.git#master

# … or from Bitbucket, public repo:
$ npm install git+ssh://[email protected]/username/my-new-project.git#master --save-dev
# Bitbucket, private repo:
$ npm install git+https://username:[email protected]/username/my-new-project.git#master
$ npm install git+ssh://[email protected]/username/my-new-project.git#master
# Or, if you published as npm package:
$ npm install my-new-project --save-dev

Simple Solution will be to match local master branch HEAD to origin/master branch HEAD

git reset --hard origin/master

PS: origin/master - is remote pointer to master branch. You can replace master with any branch name

this example will be creating logger for each minute, if you want to change for each day change the DatePattern value.

<appender name="ASYNC" class="org.apache.log4j.DailyRollingFileAppender">
   <param name="File" value="./applogs/logger.log" />
   <param name="Append" value="true" />
   <param name="Threshold" value="debug" />
   <appendToFile value="true" />
   <param name="DatePattern" value="'.'yyyy_MM_dd_HH_mm"/>
   <rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
      <param name="fileNamePattern" value="./applogs/logger_%d{ddMMMyyyy HH:mm:ss}.log"/>
      <param name="rollOver" value="TRUE"/>
   </rollingPolicy>
   <layout class="org.apache.log4j.PatternLayout">
      <param name="ConversionPattern" value="%d{ddMMMyyyy HH:mm:ss,SSS}^[%X{l4j_mdc_key}]^[%c{1}]^ %-5p %m%n" />
   </layout>
</appender>
<root>
   <level value="info" />
   <appender-ref ref="ASYNC" />
</root>

Simply execute

CKEDITOR.instances[elementId].getData();

with element id = id of element assigned the editor.

So the solution to the original problem is that you don't need both the "@see" and the "{@link...}" references on the same line. The "@link" tag is self-sufficient and, as noted, you can put it anywhere in the javadoc block. So you can mix the two approaches:

/**
 * some javadoc stuff
 * {@link com.my.package.Class#method()}
 * more stuff
 * @see com.my.package.AnotherClass
 */

Lets analyze this patch line by line.

• The first line

  diff --git a/builtin-http-fetch.c b/http-fetch.c

  is a "git diff" header in the form diff --git a/file1 b/file2. The a/ and b/ filenames are the same unless rename/copy is involved (like in our case). The --git is to mean that diff is in the "git" diff format.

• Next are one or more extended header lines. The first three

  similarity index 95%
  rename from builtin-http-fetch.c
  rename to http-fetch.c

  tell us that the file was renamed from builtin-http-fetch.c to http-fetch.c and that those two files are 95% identical (which was used to detect this rename).
  
  The last line in extended diff header, which is

  index f3e63d7..e8f44ba 100644

  tell us about mode of given file (100644 means that it is ordinary file and not e.g. symlink, and that it doesn't have executable permission bit), and about shortened hash of preimage (the version of file before given change) and postimage (the version of file after change). This line is used by git am --3way to try to do a 3-way merge if patch cannot be applied itself.
  
  

• Next is two-line unified diff header

  --- a/builtin-http-fetch.c
  +++ b/http-fetch.c

  Compared to diff -U result it doesn't have from-file-modification-time nor to-file-modification-time after source (preimage) and destination (postimage) file names. If file was created the source is /dev/null; if file was deleted, the target is /dev/null.
  If you set diff.mnemonicPrefix configuration variable to true, in place of a/ and b/ prefixes in this two-line header you can have instead c/, i/, w/ and o/ as prefixes, respectively to what you compare; see git-config(1)

• Next come one or more hunks of differences; each hunk shows one area where the files differ. Unified format hunks starts with line like

• Next comes the description of where files differ. The lines common to both files begin with a space character. The lines that actually differ between the two files have one of the following indicator characters in the left print column:

  • '+' -- A line was added here to the first file.
  • '-' -- A line was removed here from the first file.

  
  So, for example, first chunk

   #include "cache.h"
   #include "walker.h"
  
  -int cmd_http_fetch(int argc, const char **argv, const char *prefix)
  +int main(int argc, const char **argv)
   {
  +       const char *prefix;
          struct walker *walker;
          int commits_on_stdin = 0;
          int commits;
  

  means that cmd_http_fetch was replaced by main, and that const char *prefix; line was added.

  In other words, before the change, the appropriate fragment of then 'builtin-http-fetch.c' file looked like this:

  #include "cache.h"
  #include "walker.h"
  
  int cmd_http_fetch(int argc, const char **argv, const char *prefix)
  {
         struct walker *walker;
         int commits_on_stdin = 0;
         int commits;
  

  After the change this fragment of now 'http-fetch.c' file looks like this instead:

  #include "cache.h"
  #include "walker.h"
  
  int main(int argc, const char **argv)
  {
         const char *prefix;
         struct walker *walker;
         int commits_on_stdin = 0;
         int commits;
  

• There might be

  \ No newline at end of file

  line present (it is not in example diff).

As Donal Fellows said it is best to practice reading diffs on real-life examples, where you know what you have changed.

References:

• git-diff(1) manpage, section "Generating patches with -p"
• (diff.info)Detailed Unified node, "Detailed Description of Unified Format".

Almost every logging framework provides a method in which we can pass the throwable object along with a message. Like:

public trace(Marker marker, String msg, Throwable t);

They print the stacktrace of the throwable object.

Using Linux Top command

top -H -p (process id)

you could get process id of one program by this method :

ps aux | grep (your program name)

for example :

ps aux | grep user.py

Below is the core JavaScript you need to write:

As correct as the other answers may be, in the context that the quote was in, hashing is a tool that may be used in securing information, encryption is a process that takes information and makes it very difficult for unauthorized people to read/use.

Adding to @romanb brilliant answer.

This adds a little overhead in migration, because you obviously cannot create a field with not null constraint and with no default value.

// this up() migration is autogenerated, please modify it to your needs
$this->abortIf($this->connection->getDatabasePlatform()->getName() != "postgresql");

//lets add property without not null contraint        
$this->addSql("ALTER TABLE tablename ADD property BOOLEAN");

//get the default value for property       
$object = new Object();
$defaultValue = $menuItem->getProperty() ? "true":"false";

$this->addSql("UPDATE tablename SET property = {$defaultValue}");

//not you can add constraint
$this->addSql("ALTER TABLE tablename ALTER property SET NOT NULL");

With this answer, I encourage you to think why do you need the default value in the database in the first place? And usually it is to allow creating objects with not null constraint.

If you're allergic to string concatenation and don't need IE compatibility, you can use URL and URLSearchParams:

const target = new URL('https://example.com/endpoint');_x000D_
const params = new URLSearchParams();_x000D_
params.set('var1', 'foo');_x000D_
params.set('var2', 'bar');_x000D_
target.search = params.toString();_x000D_
_x000D_
console.log(target);

Or to convert an entire object's worth of parameters:

const paramsObject = {_x000D_
  var1: 'foo',_x000D_
  var2: 'bar'_x000D_
};_x000D_
_x000D_
const target = new URL('https://example.com/endpoint');_x000D_
target.search = new URLSearchParams(paramsObject).toString();_x000D_
_x000D_
console.log(target);

robotex tools which are free will let you do this but they make you enter the ip of the domain first:

1. find out the ip (there's a good ff plugin which does this but I can't post the link cos this is my first post here!)
2. do an ip search on robotex: http://www.robtex.com/ip/
3. in the results page that follows click on the domain you're interested in>
4. you are taken to a page that lists all subdomains + a load of other information such as mail server info

The appropriate way to do this is using Redux Thunk which is a popular middleware for Redux, as per Redux Thunk documentation:

"Redux Thunk middleware allows you to write action creators that return a function instead of an action. The thunk can be used to delay the dispatch of an action, or to dispatch only if a certain condition is met. The inner function receives the store methods dispatch and getState as parameters".

So basically it returns a function, and you can delay your dispatch or put it in a condition state.

So something like this is going to do the job for you:

import ReduxThunk from 'redux-thunk';

const INCREMENT_COUNTER = 'INCREMENT_COUNTER';

function increment() {
  return {
    type: INCREMENT_COUNTER
  };
}

function incrementAsync() {
  return dispatch => {
    setTimeout(() => {
      // Yay! Can invoke sync or async actions with `dispatch`
      dispatch(increment());
    }, 5000);
  };
}

As of Mongo 3.2 the answers to this question are mostly no longer correct. The new $lookup operator added to the aggregation pipeline is essentially identical to a left outer join:

https://docs.mongodb.org/master/reference/operator/aggregation/lookup/#pipe._S_lookup

From the docs:

{
   $lookup:
     {
       from: <collection to join>,
       localField: <field from the input documents>,
       foreignField: <field from the documents of the "from" collection>,
       as: <output array field>
     }
}

Of course Mongo is not a relational database, and the devs are being careful to recommend specific use cases for $lookup, but at least as of 3.2 doing join is now possible with MongoDB.

It's because you're missing position:relative; on #contentframe

<div id="contentframe" style="position:relative; top: 160px; left: 0px;">

position:absolute; positions itself against the closest ancestor that has a position that is not static. Since the default is static that is what was causing your issue.

A script I wrote for my GitBash. Accomplishes the following:

• By default pulls from origin for all branches that are setup to track origin, allows you to specify a different remote if desired.
• If your current branch is in a dirty state then it stashes your changes and will attempt to restore these changes at the end.
• For each local branch that is set up to track a remote branch will:
  • git checkout branch
  • git pull origin
• Finally, will return you to your original branch and restore state.

** I use this but have not tested thoroughly, use at own risk. See an example of this script in a .bash_alias file here.

    # Do a pull on all branches that are tracking a remote branches, will from origin by default.
    # If current branch is dirty, will stash changes and reply after pull.
    # Usage: pullall [remoteName]
    alias pullall=pullAll
    function pullAll (){
     # if -h then show help
     if [[ $1 == '-h' ]]
    then
      echo "Description: Pulls new changes from upstream on all branches that are tracking remotes."
      echo 
      echo "Usage: "
      echo "- Default: pullall"
      echo "- Specify upstream to pull from: pullall [upstreamName]"
      echo "- Help: pull-all -h"
    else

     # default remote to origin
     remote="origin"
     if [ $1 != "" ]
     then
       remote=$1
     fi

     # list all branches that are tracking remote
     # git branch -vv : list branches with their upstreams
     # grep origin : keep only items that have upstream of origin

       git checkout $branch

       echo "Pulling $remote"
       git pull $remote

     done

     echo "Switching back to $startingBranch"

That meta tag basically specifies which character set a website is written with.

Here is a definition of UTF-8:

UTF-8 (U from Universal Character Set + Transformation Format—8-bit) is a character encoding capable of encoding all possible characters (called code points) in Unicode. The encoding is variable-length and uses 8-bit code units.

It is the directory from where you run the command to execute your batch file.

When we get some error from our application, Logcat will show session filter automatically. We can create session filter by self. Just add a new logcat filter, fill the filter name form. Then fill the by application name with your application package. (for example : my application is "Adukan" and the package is "com.adukan", so I fill by application name with application package "com.adukan")

try this out let me know what happens.

This is because Oracle internally changes empty string to NULL values. Oracle simply won't let insert an empty string.

On the other hand, SQL Server would let you do what you are trying to achieve.

There are 2 workarounds here:

1. Use another column that states whether the 'description' field is valid or not
2. Use some dummy value for the 'description' field where you want it to store empty string. (i.e. set the field to be 'stackoverflowrocks' assuming your real data will never encounter such a description value)

Both are, of course, stupid workarounds :)

In some cases, I could prevent Eclipse from crashing during startup by deleting a .snap file in your workspace meta-data (.metadata/.plugins/org.eclipse.core.resources/.snap).

See also https://bugs.eclipse.org/bugs/show_bug.cgi?id=149121 (the bug has been closed, but happened to me recently)

.focus() and then .blur() something else arbitrary on your page. Since only one element can have the focus, it is transferred to that element and then removed.

There is no function to append the data in dictionary. You just assign the value against new key in existing dictionary. it will automatically add value to the dictionary.

var param  = ["Name":"Aloha","user" : "Aloha 2"]
param["questions"] = "Are you mine?"
print(param)

The output will be like

["Name":"Aloha","user" : "Aloha 2","questions" : ""Are you mine"?"]

With plans to slowly retire the long-used Objective-C, Apple has introduced a new programming language, called Swift, for designing apps and applications to run on Apple iOS devices and Apple Macintosh computers.

Apple says: "Swift is a new programming language for iOS and OS X apps that builds on the best of C and Objective-C, without the constraints of C compatibility. Swift adopts safe programming patterns and adds modern features to make programming easier, more flexible, and more fun. Swift’s clean slate, backed by the mature and much-loved Cocoa and Cocoa Touch frameworks, is an opportunity to reimagine how software development works."

        3 => "Thu",
        4 => "Fri", 
        5 => "Sat",
        6 => "Sun",
    )
?>

<script type="text/javascript">

    var jArray = <?php echo json_encode($phpArray); ?>;

    for(var i=0; i<jArray.length; i++){
        alert(jArray[i]);
    }

Wrap the text in a span or similar and use the following CSS:

}
profile(x => "testtesttesttesttest");
profile(x => `${x}${x}${x}${x}${x}`);
profile(x => x + x + x + x + x );
profile(x => { var s = x; s += x; s += x; s += x; s += x; return s; });
profile(x => [x, x, x, x, x].join(""));
profile(x => { var a = [x]; a.push(x); a.push(x); a.push(x); a.push(x); return a.join(""); });

results in node: 7.0.10

I liked Arun's answer better but there is a tiny problem and I could not comment or edit the answer. sparkContext does not have createDeataFrame, sqlContext does (as Thiago mentioned). So:

from pyspark.sql import SQLContext

sqlContext = SQLContext(sc)
schemaPeople = sqlContext.createDataFrame(RDDName)
schemaPeople.createOrReplaceTempView("RDDName")

I've come across the same issue after adding the following dependency:

implementation 'com.evernote:android-state:1.4.1'
annotationProcessor 'com.evernote:android-state-processor:1.4.1'

And the reason was that latest version of evernote uses dependencies to AndroidX, while I had support library version 27.1.1 in my project. So there was an option of upgrading support libraries to 28.0.0, as the other answers suggest, but that was a bit tricky for a large project with lots of custom views. So, I resolved the issue by downgrading evernote version to 1.3.1.

I like to avoid DOM lookups, watches, and global emitters whenever possible, so I use a more direct approach. Use a directive to assign a simple function that focuses on the directive element. Then call that function wherever needed within the scope of the controller.

Here's a simplified approach for attaching it to scope. See the full snippet for handling controller-as syntax.

Directive:

app.directive('inputFocusFunction', function () {
    'use strict';
    return {
        restrict: 'A',
        link: function (scope, element, attr) {
            scope[attr.inputFocusFunction] = function () {
                element[0].focus();
            };
        }
    };
});

and in html:

<input input-focus-function="focusOnSaveInput" ng-model="saveName">
<button ng-click="focusOnSaveInput()">Focus</button>

or in the controller:

$scope.focusOnSaveInput();

angular.module('app', [])_x000D_
  .directive('inputFocusFunction', function() {_x000D_
    'use strict';_x000D_
    return {_x000D_
      restrict: 'A',_x000D_
      link: function(scope, element, attr) {_x000D_
        // Parse the attribute to accomodate assignment to an object_x000D_
        var parseObj = attr.inputFocusFunction.split('.');_x000D_
        var attachTo = scope;_x000D_
        for (var i = 0; i < parseObj.length - 1; i++) {_x000D_
          attachTo = attachTo[parseObj[i]];_x000D_
        }_x000D_
        // assign it to a function that focuses on the decorated element_x000D_
        attachTo[parseObj[parseObj.length - 1]] = function() {_x000D_

Edited to provide more explanation about the reason for this approach and to extend the code snippet for controller-as use.

Another thing is that all libraries from google (e.g. support lib, CardView and etc.) should have identical versions

var arr = ['a','d','r','a','a','f','d'];  

//call function and pass your array, function will return an object with array values as keys and their count as the key values.
duplicatesArr(arr);

function duplicatesArr(arr){
    var obj = {}
    for(var i = 0; i < arr.length; i++){
        obj[arr[i]] = [];
        for(var x = 0; x < arr.length; x++){
            (arr[i] == arr[x]) ? obj[arr[i]].push(x) : '';
        }
        obj[arr[i]] = obj[arr[i]].length;
    }

    console.log(obj);
    return obj;
}

Here my answer :

<form onsubmit="event.preventDefault();searchOrder(event);">
...
</form>
<script>
const searchOrder = e => {
    e.preventDefault();
    const name = e.target.name.value;
    renderSearching();

    return false;
}
</script>

I add event.preventDefault(); on onsubmit and it works.

You can also try this one.

override fun registerWith( registry: PluginRegistry) {
        GeneratedPluginRegistrant.registerWith(registry as FlutterEngine)       
    //registry.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin")
    }

I think this one is far better solution than creating a new class.

No, there is no chance to do that. You just learned how important a backup can be.

Ways to insert data into hive table: for demonstration, I am using table name as table1 and table2

1) create table table2 as select * from table1 where 1=1; or create table table2 as select * from table1;

2) insert overwrite table table2 select * from table1; --it will insert data from one to another. Note: It will refresh the target.

3) insert into table table2 select * from table1; --it will insert data from one to another. Note: It will append into the target.

4) load data local inpath 'local_path' overwrite into table table1; --it will load data from local into the target table and also refresh the target table.

5) load data inpath 'hdfs_path' overwrite into table table1; --it will load data from hdfs location iand also refresh the target table. or

create table table2(
    col1 string,
    col2 string,
    col3 string)
    row format delimited fields terminated by ','
    location 'hdfs_location'; 

6) load data local inpath 'local_path' into table table1; --it will load data from local and also append into the target table.

7) load data inpath 'hdfs_path' into table table1; --it will load data from hdfs location and also append into the target table.

8) insert into table2 values('aa','bb','cc'); --Lets say table2 have 3 columns only.

9) Multiple insertion into hive table

As datetime is not stable in numpy I would use pandas for this:

In [52]: import pandas as pd

In [53]: dates = pd.DatetimeIndex(['2010-10-17', '2011-05-13', "2012-01-15"])

In [54]: dates.year
Out[54]: array([2010, 2011, 2012], dtype=int32)

Pandas uses numpy datetime internally, but seems to avoid the shortages, that numpy has up to now.

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.

To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".

To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".

Explanation:

From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):

4.3.8 ‘Local echo’

With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)

Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.

4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.

If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.

Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)

Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.

Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

Looks like your file contains ASCII characters, which are encoded in just 1 byte. If text file was containing non-ASCII character, e.g. 2-byte UTF-8, then you get just the first byte, not whole character.

This might be useful to someone also ..

You can use jQuery's $.map.

var foo = { 'alpha' : 'puffin', 'beta' : 'beagle' },
keys = $.map(foo, function(v, i){
  return i;
});

I came across this problem today, and this was my naive attempt before watching the accepted answer.

<script>
    function main() {
        var a, b, c
        var one = function() {
            if ( a != undefined  && b != undefined && c != undefined ) {
                alert("Ok")
            } else {
                alert( "¬¬ ")
            }
        }

        fakeAjaxCall( function() {
            a = "two"
            one()
        } )
        fakeAjaxCall( function() {
            b = "three"
            one()
        } )
        fakeAjaxCall( function() {
            c = "four"
            one()
        } )
    }
    function fakeAjaxCall( a ) {
        a()
    }
    main()
</script>

Pass it as an Object:

$(....).css({
    'property': 'value', 
    'property': 'value'
});

I´d say MoDisco is by far the most powerful one (though probably not the easiest one to work with).

MoDisco is a generic reverse engineering framework (so that you can customize your reverse engineering project, with MoDisco you can even reverse engineer the behaviour of the java methods, not only the structure and signatures) but also includes some predefined features like the generation of class diagrams out of Java code that you need.

From the CLI the best way is to use grep like:

php -i | grep libxml

@Pietrovismara's solution is correct but I'd just like to add: rather than having a separate line to add column names, it's possible to do this from pd.read_csv.

df = pd.read_csv('output_list.txt', sep=" ", header=None, names=["a", "b", "c"])

Multiple parameters can be given like below,

    @RequestMapping(value = "/mno/{objectKey}", method = RequestMethod.GET, produces = "application/json")
    public List<String> getBook(HttpServletRequest httpServletRequest, @PathVariable(name = "objectKey") String objectKey
      , @RequestParam(value = "id", defaultValue = "false")String id,@RequestParam(value = "name", defaultValue = "false") String name) throws Exception {
               //logic
}

Check to make sure that both score and array[x] are numerical types. You might be comparing an integer to a string...which is heartbreakingly possible in Python 2.x.

>>> 2 < "2"
True
>>> 2 > "2"
False
>>> 2 == "2"
False

Edit

Further explanation: How does Python compare string and int?

Command

du -h --max-depth=0 * | sort -hr

Output

3,5M    asdf.6000.gz
3,4M    asdf.4000.gz
3,2M    asdf.2000.gz
2,5M    xyz.PT.gz
136K    xyz.6000.gz
116K    xyz.6000p.gz
88K test.4000.gz
76K test.4000p.gz
44K test.2000.gz
8,0K    desc.common.tcl
8,0K    wer.2000p.gz
8,0K    wer.2000.gz
4,0K    ttree.3

Explanation

• du displays "disk usage"
• h is for "human readable" (both, in sort and in du)
• max-depth=0 means du will not show sizes of subfolders (remove that if you want to show all sizes of every file in every sub-, subsub-, ..., folder)
• r is for "reverse" (biggest file first)

ncdu

When I came to this question, I wanted to clean up my file system. The command line tool ncdu is way better suited to this task.

Installation on Ubuntu:

$ sudo apt-get install ncdu

Usage:

Just type ncdu [path] in the command line. After a few seconds for analyzing the path, you will see something like this:

$ ncdu 1.11 ~ Use the arrow keys to navigate, press ? for help

Java EE is a collection of specifications for developing and deploying enterprise applications.

In general, enterprise applications refer to software hosted on servers that provide the applications that support the enterprise.

The specifications (defined by Sun) describe services, application programming interfaces (APIs), and protocols.

The 13 core technologies that make up Java EE are:

1. JDBC
2. JNDI
3. EJBs
4. RMI
5. JSP
6. Java servlets
7. XML
8. JMS
9. Java IDL
10. JTS
11. JTA
12. JavaMail
13. JAF

The Java EE product provider is typically an application-server, web-server, or database-system vendor who provides classes that implement the interfaces defined in the specifications. These vendors compete on implementations of the Java EE specifications.

When a company requires Java EE experience what are they really asking for is experience using the technologies that make up Java EE. Frequently, a company will only be using a subset of the Java EE technologies.

Or use regex assertions: grep -oP '(?<=potato: ).*' file.txt

Look at the traceback:

Traceback (most recent call last):
  File "C:\Python33\lib\site-packages\bottle.py", line 821, in _cast
    out = iter(out)
TypeError: 'bool' object is not iterable

Your code isn't iterating the value, but the code receiving it is.

The solution is: return an iterable. I suggest that you either convert the bool to a string (str(False)) or enclose it in a tuple ((False,)).

Always read the traceback: it's correct, and it's helpful.

This is a modern solution I cooked up using font-awesome. Vendor extensions have been omitted for brevity.

HTML

<fieldset>
    <label for="color">Select Color</label>
    <div class="select-wrapper">
        <select id="color">
            <option>Red</option>
            <option>Blue</option>
            <option>Yellow</option>
        </select>
        <i class="fa fa-chevron-down"></i>
    </div>
</fieldset>

SCSS

fieldset {
    .select-wrapper {
        position: relative;

        select {
            appearance: none;
            position: relative;
            z-index: 1;
            background: transparent;

            + i {
                position: absolute;
                top: 40%;
                right: 15px;
            }
        }
    }

If your select element has a defined background color, then this won't work as this snippet essentially places the Chevron icon behind the select element (to allow clicking on top of the icon to still initiate the select action).

However, you can style the select-wrapper to the same size as the select element and style its background to achieve the same effect.

Check out my CodePen for a working demo that shows this bit of code on both a dark and light themed select box using a regular label and a "placeholder" label and other cleaned up styles such as borders and widths.

P.S. This is an answer I had posted to another, duplicate question earlier this year.

You'd need to reverse your collection if you want to use the for each syntax out of the box and go in reverse order.

var mystring = "this,is,a,test"
mystring.replace(/,/g, "newchar");

Use the global(g) flag

Simple DEMO

Looks like you have a typo -- "trustStrore" should be "trustStore", i.e.

System.setProperty("javax.net.ssl.trustStrore", "cacerts.jks");

should be:

System.setProperty("javax.net.ssl.trustStore", "cacerts.jks");

Programs that prompt for passwords usually set the tty into "raw" mode, and read input directly from the tty. If you spawn the subprocess in a pty you can make that work. That is what Expect does...

Try to use this with single quotes in data:

insert into table test_hive values ('1','puneet');

Or just mydict.keys() That's a builtin method call for dictionaries. Also explore mydict.values() and mydict.items().

//Ah, OP post confused me.

Spring considers that anything behind the last dot is a file extension such as .jsonor .xml and trucate it to retrieve your parameter.

So if you have /somepath/{variable} :

• /somepath/param, /somepath/param.json, /somepath/param.xml or /somepath/param.anything will result in a param with value param
• /somepath/param.value.json, /somepath/param.value.xml or /somepath/param.value.anything will result in a param with value param.value

if you change your mapping to /somepath/{variable:.+} as suggested, any dot, including the last one will be consider as part of your parameter :

• /somepath/param will result in a param with value param
• /somepath/param.json will result in a param with value param.json
• /somepath/param.xml will result in a param with value param.xml
• /somepath/param.anything will result in a param with value param.anything
• /somepath/param.value.json will result in a param with value param.value.json
• ...

If you don't care of extension recognition, you can disable it by overriding mvc:annotation-driven automagic :

<bean id="handlerMapping"
      class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">
    <property name="contentNegotiationManager" ref="contentNegotiationManager"/>
    <property name="useSuffixPatternMatch" value="false"/>
</bean>

So, again, if you have /somepath/{variable} :

• /somepath/param, /somepath/param.json, /somepath/param.xml or /somepath/param.anything will result in a param with value param
• /somepath/param.value.json, /somepath/param.value.xml or /somepath/param.value.anything will result in a param with value param.value

note : the difference from the default config is visible only if you have a mapping like somepath/something.{variable}. see Resthub project issue

if you want to keep extension management, since Spring 3.2 you can also set the useRegisteredSuffixPatternMatch property of RequestMappingHandlerMapping bean in order to keep suffixPattern recognition activated but limited to registered extension.

Here you define only json and xml extensions :

<bean id="handlerMapping"
      class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">
    <property name="contentNegotiationManager" ref="contentNegotiationManager"/>
    <property name="useRegisteredSuffixPatternMatch" value="true"/>
</bean>

<bean id="contentNegotiationManager" class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean">
    <property name="favorPathExtension" value="false"/>
    <property name="favorParameter" value="true"/>
    <property name="mediaTypes">
        <value>
            json=application/json
            xml=application/xml
        </value>
    </property>
</bean>

Note that mvc:annotation-driven accepts now a contentNegotiation option to provide a custom bean but the property of RequestMappingHandlerMapping has to be changed to true (default false) (cf. https://jira.springsource.org/browse/SPR-7632).

For that reason, you still have to override the all mvc:annotation-driven configuration. I opened a ticket to Spring to ask for a custom RequestMappingHandlerMapping : https://jira.springsource.org/browse/SPR-11253. Please vote if you are intereted in.

While overriding, be carreful to consider also custom Execution management overriding. Otherwise, all your custom Exception mappings will fail. You will have to reuse messageCoverters with a list bean :

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" />
<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean" />

<util:list id="messageConverters">
    <bean class="your.custom.message.converter.IfAny"></bean>

    <bean class="org.springframework.http.converter.xml.XmlAwareFormHttpMessageConverter"></bean>
    <bean class="org.springframework.http.converter.xml.Jaxb2RootElementHttpMessageConverter"></bean>
    <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"></bean>
</util:list>

<bean name="exceptionHandlerExceptionResolver"
      class="org.springframework.web.servlet.mvc.method.annotation.ExceptionHandlerExceptionResolver">
    <property name="order" value="0"/>
    <property name="messageConverters" ref="messageConverters"/>
</bean>

    <property name="webBindingInitializer">
        <bean class="org.springframework.web.bind.support.ConfigurableWebBindingInitializer">
            <property name="conversionService" ref="conversionService" />
            <property name="validator" ref="validator" />
        </bean>
    </property>

I implemented, in the open source project Resthub that I am part of, a set of tests on these subjects : see https://github.com/resthub/resthub-spring-stack/pull/219/files & https://github.com/resthub/resthub-spring-stack/issues/217

var contains = function(needle) {
    // Per spec, the way to identify NaN is that it is not equal to itself
    var findNaN = needle !== needle;
    var indexOf;

    if(!findNaN && typeof Array.prototype.indexOf === 'function') {
        indexOf = Array.prototype.indexOf;
    } else {
        indexOf = function(needle) {
            var i = -1, index = -1;

            for(i = 0; i < this.length; i++) {
                var item = this[i];

                if((findNaN && item !== item) || item === needle) {
                    index = i;
                    break;
                }
            }

            return index;
        };
    }

    return indexOf.call(this, needle) > -1;
};

You can use it like this:

var myArray = [0,1,2],
    needle = 1,
    index = contains.call(myArray, needle); // true

CodePen validation/usage

Super late here and I still couldn't uninstall using sudo as the other answers suggest. What did it for me was checking where cordova was installed by running

which cordova

it will output something like this

/usr/local/bin/

then removing by

rm -rf /usr/local/bin/cordova

To summarize Laryx Decidua's answer:

define and use a function like the following

plot.with.errorbars <- function(x, y, err, ylim=NULL, ...) {
  if (is.null(ylim))
    ylim <- c(min(y-err), max(y+err))
  plot(x, y, ylim=ylim, pch=19, ...)
  arrows(x, y-err, x, y+err, length=0.05, angle=90, code=3)
}

where one can override the automatic ylim, and also pass extra parameters such as main, xlab, ylab.

Uncaught TypeError: undefined is not a function example_app.js:7

This error message tells the whole story. On this line, you are trying to execute a function. However, whatever is being executed is not a function! Instead, it's undefined.

So what's on example_app.js line 7? Looks like this:

var tasks = new ExampleApp.Collections.Tasks(data.tasks);

There is only one function being run on that line. We found the problem! ExampleApp.Collections.Tasks is undefined.

So lets look at where that is declared:

var Tasks = Backbone.Collection.extend({
    model: Task,
    url: '/tasks'
});

If that's all the code for this collection, then the root cause is right here. You assign the constructor to global variable, called Tasks. But you never add it to the ExampleApp.Collections object, a place you later expect it to be.

Change that to this, and I bet you'd be good.

ExampleApp.Collections.Tasks = Backbone.Collection.extend({
    model: Task,
    url: '/tasks'
});

See how important the proper names and line numbers are in figuring this out? Never ever regard errors as binary (it works or it doesn't). Instead read the error, in most cases the error message itself gives you the critical clues you need to trace through to find the real issue.

In Javascript, when you execute a function, it's evaluated like:

expression.that('returns').aFunctionObject(); // js
execute -> expression.that('returns').aFunctionObject // what the JS engine does

That expression can be complex. So when you see undefined is not a function it means that expression did not return a function object. So you have to figure out why what you are trying to execute isn't a function.

And in this case, it was because you didn't put something where you thought you did.

See, here you are overriding one of the method of the base class hence if you like to call base class method from inherited class then you have to use super keyword in the same method of the inherited class.

I would prefer:

try
{
    ...
}
catch (FooException fe){
   throw fe;
}
catch (Exception e)
{
    // Note: don't catch all exceptions like this unless you know what you
    // are doing.
    ...
}

try this one out.

<label for="user">user</label>
<input type="text" name="user" 
onfocus="if(this.value==this.defaultValue)this.value=''"    
onblur="if(this.value=='')this.value=this.defaultValue" 
value="username" maxlength="19" />

hope this helps.

Another cross-browser approach based on above solution

function doScrollTo(to, duration) {
    var element = document.documentElement;

        var start = element.scrollTop,
        change = to - start,
        increment = 20,
        i = 0;

    var animateScroll = function(elapsedTime) {
        elapsedTime += increment;
        var position = easeInOut(elapsedTime, start, change, duration);
        if (i === 1 && window.scrollY === start) {
            element = document.body;
            start = element.scrollTop;
        }
        element.scrollTop = position;
        if (!i) i++;
        if (elapsedTime < duration) {
            setTimeout(function() {
                animateScroll(elapsedTime);
            }, increment);
        }
    };

    animateScroll(0);
}

The trick is to control the actual scroll change, and if it is zero, change the scroll element.

To rollback the last migration you can do:

rake db:rollback

If you want to rollback a specific migration with a version you should do:

rake db:migrate:down VERSION=YOUR_MIGRATION_VERSION

If the migration file you want to rollback was called db/migrate/20141201122027_create_some_table.rb, then the VERSION for that migration is 20141201122027, which is the timestamp of when that migration was created, and the command to roll back that migration would be:

rake db:migrate:down VERSION=20141201122027

You can just implement a user-defined type like the following:

type Nullable<T> = T | undefined | null;

var foo: Nullable<number> = 10; // ok
var bar: Nullable<number> = true; // type 'true' is not assignable to type 'Nullable<number>'
var baz: Nullable<number> = null; // ok

var arr1: Nullable<Array<number>> = [1,2]; // ok
var obj: Nullable<Object> = {}; // ok

 // Type 'number[]' is not assignable to type 'string[]'. 
 // Type 'number' is not assignable to type 'string'
var arr2: Nullable<Array<string>> = [1,2];

Another reason could be that you acidentically added a Javascript nature to your project unintentionally (i just did this by accident) which enables javascript error checking.

removing this ....javascriptnature from your project fixes that.

(this is ofcourse only if you dont want eclipse to realise you have any JS)

What browser are you testing in?

What DOCType have you set?

How exactly are you declaring your CSS?

Are you sure you haven't missed a ; before/after the overflow-y: scroll?

I've just tested the following in IE7 and Firefox and it works fine

<!-- Scroll bar present but disabled when less content -->_x000D_
<div style="width: 200px; height: 100px; overflow-y: scroll;">_x000D_
  test_x000D_
</div>_x000D_
_x000D_
<!-- Scroll bar present and enabled when more contents -->        _x000D_
<div style="width: 200px; height: 100px; overflow-y: scroll;">_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
</div>

A ClusterIP exposes the following:

• spec.clusterIp:spec.ports[*].port

You can only access this service while inside the cluster. It is accessible from its spec.clusterIp port. If a spec.ports[*].targetPort is set it will route from the port to the targetPort. The CLUSTER-IP you get when calling kubectl get services is the IP assigned to this service within the cluster internally.

A NodePort exposes the following:

• <NodeIP>:spec.ports[*].nodePort
• spec.clusterIp:spec.ports[*].port

If you access this service on a nodePort from the node's external IP, it will route the request to spec.clusterIp:spec.ports[*].port, which will in turn route it to your spec.ports[*].targetPort, if set. This service can also be accessed in the same way as ClusterIP.

Your NodeIPs are the external IP addresses of the nodes. You cannot access your service from spec.clusterIp:spec.ports[*].nodePort.

A LoadBalancer exposes the following:

• spec.loadBalancerIp:spec.ports[*].port
• <NodeIP>:spec.ports[*].nodePort
• spec.clusterIp:spec.ports[*].port

You can access this service from your load balancer's IP address, which routes your request to a nodePort, which in turn routes the request to the clusterIP port. You can access this service as you would a NodePort or a ClusterIP service as well.

myList = [i.split('\t')[0] for i in myList] 

// get the OPTION we want selected
var $option = $('#SelectList').children('option[value="'+ id +'"]');
// and now set the option we want selected
$option.attr('selected', true);??

<span style="color:orange;">orange text</span>

Is the only way I know of barring the font tag.

This is how I realised the loading indicator by an Glyphicon:

<!DOCTYPE html>
<html>

<head>
    <title>Demo</title>

    <link rel="stylesheet" href="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.6/css/bootstrap.min.css">
    <script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.12.4.min.js"></script>
    <script src="https://ajax.aspnetcdn.com/ajax/bootstrap/3.3.6/bootstrap.min.js"></script>

    <style>
        .gly-ani {
          animation: ani 2s infinite linear;
        }
        @keyframes ani {
          0% {
            transform: rotate(0deg);
          }
          100% {
            transform: rotate(359deg);
          }
        }
    </style>  
</head>

<body>
<div class="container">

    <span class="glyphicon glyphicon-refresh gly-ani" style="font-size:40px;"></span>

</div>
</body>

</html>

You can use the below code on your string and you will get the complete string without html part.

string title = "<b> Hulk Hogan's Celebrity Championship Wrestling &nbsp;&nbsp;&nbsp;<font color=\"#228b22\">[Proj # 206010]</font></b>&nbsp;&nbsp;&nbsp; (Reality Series, &nbsp;)".Replace("&nbsp;",string.Empty);            
        string s = Regex.Replace(title, "<.*?>", String.Empty);

If you are getting the following error while connecting the mysql (either local or mysql container running the mysql):

java.sql.SQLNonTransientConnectionException: Public Key Retrieval is not allowed

Solution: Add the following line in your database service:

command: --default-authentication-plugin=mysql_native_password

Some time you can solve problem through MySQL Administrator wizard. In

Startup variables > Advanced >

and set Def. char Set:utf8

Maybe this config need restart MySQL.
