This is the UIKeyboardTypes for Swift 3:

public enum UIKeyboardType : Int {

    case `default` // Default type for the current input method.
    case asciiCapable // Displays a keyboard which can enter ASCII characters
    case numbersAndPunctuation // Numbers and assorted punctuation.
    case URL // A type optimized for URL entry (shows . / .com prominently).
    case numberPad // A number pad with locale-appropriate digits (0-9, ?-?, ?-?, etc.). Suitable for PIN entry.
    case phonePad // A phone pad (1-9, *, 0, #, with letters under the numbers).
    case namePhonePad // A type optimized for entering a person's name or phone number.
    case emailAddress // A type optimized for multiple email address entry (shows space @ . prominently).

    @available(iOS 4.1, *)
    case decimalPad // A number pad with a decimal point.

    @available(iOS 5.0, *)
    case twitter // A type optimized for twitter text entry (easy access to @ #)

    @available(iOS 7.0, *)
    case webSearch // A default keyboard type with URL-oriented addition (shows space . prominently).

    @available(iOS 10.0, *)
    case asciiCapableNumberPad // A number pad (0-9) that will always be ASCII digits.


    public static var alphabet: UIKeyboardType { get } // Deprecated
}

This is an example to use a keyboard type from the list:

textField.keyboardType = .numberPad

this worked for me though... i wanted to display the image after the pencil icon is being clicked... and i wanted it seamless.. and this was my approach..

i created an input[file] element and made it hidden,

<input type="file" id="upl" style="display:none"/>

this input-file's click event will be trigged by the getImage function.

<a href="javascript:;" onclick="getImage()"/>
    <img src="/assets/pen.png"/>
</a>

<script>
     function getImage(){
       $('#upl').click();
     }
</script>

this is done while listening to the change event of the input-file element with ID of #upl.

   $(document).ready(function(){_x000D_
     _x000D_
       $('#upl').bind('change', function(evt){_x000D_
         _x000D_
    var preview = $('#logodiv').find('img');_x000D_
    var file    = evt.target.files[0];_x000D_
    var reader  = new FileReader();_x000D_
  _x000D_
    reader.onloadend = function () {_x000D_
   $('#logodiv > img')_x000D_
    .prop('src',reader.result)  //set the scr prop._x000D_
    .prop('width', 216);  //set the width of the image_x000D_
    .prop('height',200);  //set the height of the image_x000D_
    }_x000D_
  _x000D_
    if (file) {_x000D_
   reader.readAsDataURL(file);_x000D_
    } else {_x000D_
   preview.src = "";_x000D_
    }_x000D_
  _x000D_
    });_x000D_
_x000D_
   })

and BOOM!!! - it WORKS....

Another option is replacing double quotes with single quotes if you don't mind whatever it is. But I don't mention this one:

<option value='"asd'>test</option>

I mention this one:

<option value="'asd">test</option>

In my case I used this solution.

It is best to force the highest mode possible. That can be accomplished by adding:

<meta http-equiv="X-UA-Compatible" content="IE=edge">

and it is always good to include the polyfill library in order to support IE:

<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>

before any script.

You need to use this line of code to resolve your problem:

__block Person *aPerson = nil;

I am using Android 1.6 and had one external JAR file. What worked for me was to remove all libraries, right-click project and select Android Tools -> *Fix Project Properties (which added back Android 1.6) and then add back the external JAR file.

Another quick and dirty answer is that you can just convert your list to an array using:

import numpy as np
arr = np.asarray(listname)

According to the manual this should work:

Custom key/value method:

You can include an operator in the first parameter in order to control the comparison:

$this->db->where('name !=', $name);
$this->db->where('id <', $id);
Produces: WHERE name != 'Joe' AND id < 45

Search for $this->db->where(); and look at item #2.

You can't easily use a range here because the iterator you get from a map refers to a std::pair, where the iterators you would use to insert into a vector refers to an object of the type stored in the vector, which is (if you are discarding the key) not a pair.

I really don't think it gets much cleaner than the obvious:

#include <map>
#include <vector>
#include <string>
using namespace std;

int main() {
    typedef map <string, int> MapType;
    MapType m;  
    vector <int> v;

    // populate map somehow

    for( MapType::iterator it = m.begin(); it != m.end(); ++it ) {
        v.push_back( it->second );
    }
}

which I would probably re-write as a template function if I was going to use it more than once. Something like:

template <typename M, typename V> 
void MapToVec( const  M & m, V & v ) {
    for( typename M::const_iterator it = m.begin(); it != m.end(); ++it ) {
        v.push_back( it->second );
    }
}

Console.Write((int)response.StatusCode);

HttpStatusCode (the type of response.StatusCode) is an enumeration where the values of the members match the HTTP status codes, e.g.

public enum HttpStatusCode
{
    ...
    Moved = 301,
    OK = 200,
    Redirect = 302,
    ...
}

To get a list of tables for the current database in DB2 -->

Connect to the database:

db2 connect to DATABASENAME user USER using PASSWORD

Run this query:

db2 LIST TABLES

This is the equivalent of SHOW TABLES in MySQL.

You may need to execute 'set schema myschema' to the correct schema before you run the list tables command. By default upon login your schema is the same as your username - which often won't contain any tables. You can use 'values current schema' to check what schema you're currently set to.

One line ultimate solution:

[ "$(pgrep -fn $0)" -ne "$(pgrep -fo $0)" ] && echo "At least 2 copies of $0 are running"

This is happening be cause you have 2 classes with same name. For, example, I have 2 SOAP web-services named settings and settings2 both have the same class GetEmployee and this is ambiguous proving the error.

{ "date" : "1000000" } in your Mongo doc seems suspect. Since it's a number, it should be { date : 1000000 }

It's probably a type mismatch. Try post.findOne({date: "1000000"}, callback) and if that works, you have a typing issue.

you probably don't have the correct arch in that lib, you can do a

file /private/var/mobile/Containers/Bundle/Application/3FC2DC5C-A908-42C4-8508-1320E01E0D5B/testapp.app/Frameworks/libswiftCore.dylib

and it should show you the arch's that are in that library... I am not sure how you are linking, but it probably isn't the right way (if libswiftcore is a factory library, if it is some add on library then it probably isn't compiled correctly)

There are a few answers that provide solutions with react-app-rewired, but customize-cra exposes a special removeModuleScopePlugin() API which is a bit more elegant. (It's the same solution, but abstracted away by the customize-cra package.)

npm i --save-dev react-app-rewired customize-cra

package.json

"scripts": {
    - "start": "react-scripts start"
    + "start": "react-app-rewired start",
    ...
},

config-overrides.js

const { removeModuleScopePlugin } = require('customize-cra')

module.exports = removeModuleScopePlugin()

Python comes with numerous ways of formatting strings:

New style .format(), which supports a rich formatting mini-language:

>>> temperature = 10
>>> print("the furnace is now {} degrees!".format(temperature))
the furnace is now 10 degrees!

Old style % format specifier:

>>> print("the furnace is now %d degrees!" % temperature)
the furnace is now 10 degrees!

In Py 3.6 using the new f"" format strings:

>>> print(f"the furnace is now {temperature} degrees!")
the furnace is now 10 degrees!

Or using print()s default separator:

>>> print("the furnace is now", temperature, "degrees!")
the furnace is now 10 degrees!

And least effectively, construct a new string by casting it to a str() and concatenating:

>>> print("the furnace is now " + str(temperature) + " degrees!")
the furnace is now 10 degrees!

Or join()ing it:

>>> print(' '.join(["the furnace is now", str(temperature), "degrees!"]))
the furnace is now 10 degrees!

Please note that whenever you use

regexp_like(column, '[A-Z]')

Oracle's regexp engine will match certain characters from the Latin-1 range as well: this applies to all characters that look similar to ASCII characters like Ä->A, Ö->O, Ü->U, etc., so that [A-Z] is not what you know from other environments like, say, Perl.

Instead of fiddling with regular expressions try changing for the NVARCHAR2 datatype prior to character set upgrade.

Another approach: instead of cutting away part of the fields' contents you might try the SOUNDEX function, provided your database contains European characters (i.e. Latin-1) characters only. Or you just write a function that translates characters from the Latin-1 range into similar looking ASCII characters, like

• å => a
• ä => a
• ö => o

of course only for text blocks exceeding 4000 bytes when transformed to UTF-8.

double value = 2.8032739273;
String formattedValue = value.toStringAsFixed(3);

You can pass "<>" (including the quotes) as the parameter for criteria. This basically says, as long as its not empty/blank, count it. I believe this is what you want.

=COUNTIF(A1:A10, "<>") 

Otherwise you can use CountA as Scott suggests

You are simply sending signals to the processes. kill is a command to send those signals.

The keyboard command Ctrl+C sends a SIGINT, kill -9 sends a SIGKILL, and kill -15 sends a SIGTERM.

What signal do you want to send to your server to end it?

Here my approach,it may be useful to others.

2. Tool Generates Hadoop script with all csv files and following is a sample of generated Hadoop script to insert csv into Hadoop

   #!/bin/bash -v
   
   hadoop fs -put ./AllstarFull.csv /user/bigdataproject/AllstarFull.csv
   hive -f ./AllstarFull.hive
   
   hadoop fs -put ./Appearances.csv /user/bigdataproject/Appearances.csv
   hive -f ./Appearances.hive
   
   hadoop fs -put ./AwardsManagers.csv /user/bigdataproject/AwardsManagers.csv
   hive -f ./AwardsManagers.hive

Remove the function and check the output of:

var_dump(function_exists('parseDate'));

In which case, change the name of the function.

If you get false, you're including the file with that function twice, replace :

include

by

include_once

And replace :

require

by

require_once

Try the following code:

For PHP 5.4.0 and above:

$filename = basename(parse_url('http://learner.com/learningphp.php?lid=1348')['path']);

For PHP Version < 5.4.0

$parsed = parse_url('http://learner.com/learningphp.php?lid=1348');
$filename = basename($parsed['path']);

You know, sometimes it's just easier to work with a BackgroundWorker regardless of if you're using Windows Forms, WPF or whatever technology. The neat part about these guys is you get threading without having to worry too much about where you're thread is executing, which is great for simple tasks.

Before using a BackgroundWorker consider first if you wish to cancel a thread (closing app, user cancellation) then you need to decide if your thread should check for cancellations or if it should be thrust upon the execution itself.

BackgroundWorker.CancelAsync() will set CancellationPending to true but won't do anything more, it's then the threads responsibility to continually check this, keep in mind also that you could end up with a race condition in this approach where your user cancelled, but the thread completed prior to testing for CancellationPending.

Thread.Abort() on the other hand will throw an exception within the thread execution which enforces cancellation of that thread, you must be careful about what might be dangerous if this exception was suddenly raised within the execution though.

Threading needs very careful consideration no matter what the task, for some further reading:

Try setting the timeout value in your web service proxy class:

myProxy.Timeout = 100000; //in milliseconds, e.g. 100 seconds

Create a login for the user

Drop and re-create the user, WITH the login you created.

There are other topics discussing how to replicate the permissions of your user. I recommend that you take the opportunity to define those permissions in a Role and call sp_addrolemember to add the user to the Role.

That depends on the nature of the information you want to return.

If it is a single integer value, you can use the return statement

 create proc myproc
 as 
 begin
     return 1
 end
 go
 declare @i int
 exec @i = myproc

If you have a non integer value, or a number of scalar values, you can use output parameters

create proc myproc
  @a int output,
  @b varchar(50) output
as
begin
  select @a = 1, @b='hello'
end
go
declare @i int, @j varchar(50)
exec myproc @i output, @j output

If you want to return a dataset, you can use insert exec

create proc myproc
as 
begin
     select name from sysobjects
end
go

declare @t table (name varchar(100))
insert @t (name)
exec myproc

You can even return a cursor but that's just horrid so I shan't give an example :)

next - it's like return, but for blocks! (So you can use this in any proc/lambda too.)

That means you can also say next n to "return" n from the block. For instance:

puts [1, 2, 3].map do |e|
  next 42 if e == 2
  e
end.inject(&:+)

This will yield 46.

Note that return always returns from the closest def, and never a block; if there's no surrounding def, returning is an error.

Using return from within a block intentionally can be confusing. For instance:

def my_fun
  [1, 2, 3].map do |e|
    return "Hello." if e == 2
    e
  end
end

my_fun will result in "Hello.", not [1, "Hello.", 2], because the return keyword pertains to the outer def, not the inner block.

There is no built-in way to do a real clone (deep copy) of an object in node.js. There are some tricky edge cases so you should definitely use a library for this. I wrote such a function for my simpleoo library. You can use the deepCopy function without using anything else from the library (which is quite small) if you don't need it. This function supports cloning multiple data types, including arrays, dates, and regular expressions, it supports recursive references, and it also works with objects whose constructor functions have required parameters.

Here is the code:

//If Object.create isn't already defined, we just do the simple shim, without the second argument,
//since that's all we need here
var object_create = Object.create;
if (typeof object_create !== 'function') {
    object_create = function(o) {
        function F() {}
        F.prototype = o;
        return new F();
    };
}

You would need to set DATEFIRST. Take a look at this article. I believe this should help.

The best answer would be to use XOR and to use it in one line would be cool.

    (x ^= y), (y ^= x), (x ^= y);

x,y are variables and the comma between them introduces the sequence points so it does not become compiler dependent. Cheers!

very easy : use "\n"

    String aString1 = "abcd";
    String aString2 = "1234";
    mSomeTextView.setText(aString1 + "\n" + aString2);

\n corresponds to ASCII char 0xA, which is 'LF' or line feed

\r corresponds to ASCII char 0xD, which is 'CR' or carriage return

this dates back from the very first typewriters, where you could choose to do only a line feed (and type just a line lower), or a line feed + carriage return (which also moves to the beginning of a line)

on Android / java the \n corresponds to a carriage return + line feed, as you would otherwise just 'overwrite' the same line

^wp.*\.php$ Should do the trick.

The .* means "any character, repeated 0 or more times". The next . is escaped because it's a special character, and you want a literal period (".php"). Don't forget that if you're typing this in as a literal string in something like C#, Java, etc., you need to escape the backslash because it's a special character in many literal strings.

grep

For non-greedy match in grep you could use a negated character class. In other words, try to avoid wildcards.

For example, to fetch all links to jpeg files from the page content, you'd use:

grep -o '"[^" ]\+.jpg"'

To deal with multiple line, pipe the input through xargs first. For performance, use ripgrep.

tl;dr:

concat and append currently sort the non-concatenation index (e.g. columns if you're adding rows) if the columns don't match. In pandas 0.23 this started generating a warning; pass the parameter sort=True to silence it. In the future the default will change to not sort, so it's best to specify either sort=True or False now, or better yet ensure that your non-concatenation indices match.

The warning is new in pandas 0.23.0:

In a future version of pandas pandas.concat() and DataFrame.append() will no longer sort the non-concatenation axis when it is not already aligned. The current behavior is the same as the previous (sorting), but now a warning is issued when sort is not specified and the non-concatenation axis is not aligned, link.

More information from linked very old github issue, comment by smcinerney :

When concat'ing DataFrames, the column names get alphanumerically sorted if there are any differences between them. If they're identical across DataFrames, they don't get sorted.

This sort is undocumented and unwanted. Certainly the default behavior should be no-sort.

After some time the parameter sort was implemented in pandas.concat and DataFrame.append:

sort : boolean, default None

Sort non-concatenation axis if it is not already aligned when join is 'outer'. The current default of sorting is deprecated and will change to not-sorting in a future version of pandas.

Explicitly pass sort=True to silence the warning and sort. Explicitly pass sort=False to silence the warning and not sort.

This has no effect when join='inner', which already preserves the order of the non-concatenation axis.

So if both DataFrames have the same columns in the same order, there is no warning and no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['a', 'b'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['b', 'a'])

print (pd.concat([df1, df2]))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

But if the DataFrames have different columns, or the same columns in a different order, pandas returns a warning if no parameter sort is explicitly set (sort=None is the default value):

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))

FutureWarning: Sorting because non-concatenation axis is not aligned.

   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=True))
   a  b

If the DataFrames have different columns, but the first columns are aligned - they will be correctly assigned to each other (columns a and b from df1 with a and b from df2 in the example below) because they exist in both. For other columns that exist in one but not both DataFrames, missing values are created.

Lastly, if you pass sort=True, columns are sorted alphanumerically. If sort=False and the second DafaFrame has columns that are not in the first, they are appended to the end with no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8], 'e':[5, 0]}, 
                    columns=['b', 'a','e'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3], 'c':[2, 8], 'd':[7, 0]}, 
                    columns=['c','b','a','d'])

print (pd.concat([df1, df2]))

FutureWarning: Sorting because non-concatenation axis is not aligned.

   a  b    c    d    e
0  1  0  NaN  NaN  5.0
1  2  8  NaN  NaN  0.0

1  5  3  8.0  0.0  NaN

print (pd.concat([df1, df2], sort=True))

print (pd.concat([df1, df2], sort=False))

1  8  2  0.0  NaN  NaN
0  7  4  NaN  2.0  7.0
1  3  5  NaN  8.0  0.0

In your code:

placement_by_video_summary = placement_by_video_summary.drop(placement_by_video_summary_new.index)
                                                       .append(placement_by_video_summary_new, sort=True)
                                                       .sort_index()

if re.search(r'pattern', string):

Simple if-test:

if re.search(r'ing\b', "seeking a great perhaps"):     # any words end with ing?
    print("yes")

Pattern check, extract a substring, case insensitive:

match_object = re.search(r'^OUGHT (.*) BE$', "ought to be", flags=re.IGNORECASE)
if match_object:
    assert "to" == match_object.group(1)     # what's between ought and be?

Notes:

• Use re.search() not re.match. Match restricts to the start of strings, a confusing convention if you ask me. If you do want a string-starting match, use caret or \A instead, re.search(r'^...', ...)

• Use raw string syntax r'pattern' for the first parameter. Otherwise you would need to double up backslashes, as in re.search('ing\\b', ...)

• In this example, \b is a special sequence meaning word-boundary in regex. Not to be confused with backspace.

• re.search() returns None if it doesn't find anything, which is always falsy.

• re.search() returns a Match object if it finds anything, which is always truthy.

• a group is what matched inside parentheses

• group numbering starts at 1

For a simple List structure the most efficient way seems to be using the Predicate RemoveAll implementation.

Eg.

 workSpace.RoleAssignments.RemoveAll(x =>x.Member.Name == shortName);

The reasons are:

1. The Predicate/Linq RemoveAll method is implemented in List and has access to the internal array storing the actual data. It will shift the data and resize the internal array.
2. The RemoveAt method implementation is quite slow, and will copy the entire underlying array of data into a new array. This means reverse iteration is useless for List

If you are stuck implementing this in a the pre c# 3.0 era. You have 2 options.

• The easily maintainable option. Copy all the matching items into a new list and and swap the underlying list.

Eg.

List<int> list2 = new List<int>() ; 
foreach (int i in GetList())
{
    if (!(i % 2 == 0))
    {
        list2.Add(i);
    }
}
list2 = list2;

Or

• The tricky slightly faster option, which involves shifting all the data in the list down when it does not match and then resizing the array.

If you are removing stuff really frequently from a list, perhaps another structure like a HashTable (.net 1.1) or a Dictionary (.net 2.0) or a HashSet (.net 3.5) are better suited for this purpose.

Make sure the user has a localhost entry in the users table. That was the problem I was having. EX:

CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';

Presumably this would work:

IF(compliment = 'set' OR compliment = 'Y' OR compliment = 1, 'Y', 'N') AS customer_compliment

In the function declaration you have to type as

VOID FUN(INT *a[]);
/*HERE YOU CAN TAKE ANY FUNCTION RETURN TYPE HERE I CAN TAKE VOID AS THE FUNCTION RETURN  TYPE FOR THE FUNCTION FUN*/
//IN THE FUNCTION HEADER WE CAN WRITE AS FOLLOWS
void fun(int *a[])
//in the function body we can use as
a[i]=var

// Get an global variable isApiCallingInProgress

//  check isApiCallingInProgress 
if (!isApiCallingInProgress) {
// set it to isApiCallingInProgress true
      isApiCallingInProgress = true;

      // set timeout
      setTimeout(() => {
         // Api call will go here

        // then set variable again as false
        isApiCallingInProgress = false;     
      }, 1000);
}

This worked:

$("#theSelectId").prepend("<option value='' selected='selected'></option>");

Firebug Output:

<select id="theSelectId">
  <option selected="selected" value=""/>
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>

You could also use .prependTo if you wanted to reverse the order:

?$("<option>", { value: '', selected: true }).prependTo("#theSelectId");???????????

ANSWER: <embed src="https://YOURDOMAIN.com/PAGE.HTM" style="width:100%; height: 50vw;">

Couple of problems:

The while should be a for You are not returning a value but you have declared a return type of double

double average = sum / data.length;;

sum and data.length are both ints so the division will return an int - check your types

double semi-colon, probably won't break it, just looks odd.

Generally when people are trying to animate display: none what they really want is:

1. Fade content in, and
2. Have the item not take up space in the document when hidden

Most popular answers use visibility, which can only achieve the first goal, but luckily it's just as easy to achieve both by using position.

Since position: absolute removes the element from typing document flow spacing, you can toggle between position: absolute and position: static (global default), combined with opacity. See the below example.

.content-page {_x000D_
  position:absolute;_x000D_
  opacity: 0;_x000D_
}_x000D_
_x000D_
.content-page.active {_x000D_
  position: static;_x000D_
  opacity: 1;_x000D_
  transition: opacity 1s linear;_x000D_
}

Not an answer, per se, but an observation that seems to have been overlooked.

The description for carat ranges:

see: https://github.com/npm/node-semver#caret-ranges-123-025-004

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

Means that ^10.2.3 matches 10.2.3 <= v < 20.0.0

I don't think that's what they meant. Pulling in versions 11.x.x through 19.x.x will break your code.

I think they meant left most non-zero number field. There is nothing in SemVer that requires number-fields to be single-digit.

Try this so you don't need to worry about where your logs are:

dmesg -T | egrep -i 'killed process'

-T - readable timestamps

It's taking the ID , dividing it by 2 and checking if the remainder is not zero; meaning, it's an odd ID.

How about this:

//Repeats a character specified number of times
public static string Repeat(char character,int numberOfIterations)
{
    return "".PadLeft(numberOfIterations, character);
}

//Call the Repeat method
Console.WriteLine(Repeat('\t',40));

Logical operators for boolean indexing in Pandas

It's important to realize that you cannot use any of the Python logical operators (and, or or not) on pandas.Series or pandas.DataFrames (similarly you cannot use them on numpy.arrays with more than one element). The reason why you cannot use those is because they implicitly call bool on their operands which throws an Exception because these data structures decided that the boolean of an array is ambiguous:

>>> import numpy as np
>>> import pandas as pd
>>> arr = np.array([1,2,3])
>>> s = pd.Series([1,2,3])
>>> df = pd.DataFrame([1,2,3])
>>> bool(arr)
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()
>>> bool(s)
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
>>> bool(df)
ValueError: The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

I did cover this more extensively in my answer to the "Truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all()" Q+A.

NumPys logical functions

However NumPy provides element-wise operating equivalents to these operators as functions that can be used on numpy.array, pandas.Series, pandas.DataFrame, or any other (conforming) numpy.array subclass:

• and has np.logical_and
• or has np.logical_or
• not has np.logical_not
• numpy.logical_xor which has no Python equivalent but is a logical "exclusive or" operation

So, essentially, one should use (assuming df1 and df2 are pandas DataFrames):

np.logical_and(df1, df2)
np.logical_or(df1, df2)
np.logical_not(df1)
np.logical_xor(df1, df2)

Bitwise functions and bitwise operators for booleans

However in case you have boolean NumPy array, pandas Series, or pandas DataFrames you could also use the element-wise bitwise functions (for booleans they are - or at least should be - indistinguishable from the logical functions):

• bitwise and: np.bitwise_and or the & operator
• bitwise or: np.bitwise_or or the | operator
• bitwise not: np.invert (or the alias np.bitwise_not) or the ~ operator
• bitwise xor: np.bitwise_xor or the ^ operator

Typically the operators are used. However when combined with comparison operators one has to remember to wrap the comparison in parenthesis because the bitwise operators have a higher precedence than the comparison operators:

(df1 < 10) | (df2 > 10)  # instead of the wrong df1 < 10 | df2 > 10

This may be irritating because the Python logical operators have a lower precendence than the comparison operators so you normally write a < 10 and b > 10 (where a and b are for example simple integers) and don't need the parenthesis.

Differences between logical and bitwise operations (on non-booleans)

It is really important to stress that bit and logical operations are only equivalent for boolean NumPy arrays (and boolean Series & DataFrames). If these don't contain booleans then the operations will give different results. I'll include examples using NumPy arrays but the results will be similar for the pandas data structures:

>>> import numpy as np
>>> a1 = np.array([0, 0, 1, 1])
>>> a2 = np.array([0, 1, 0, 1])

>>> np.logical_and(a1, a2)
array([False, False, False,  True])
>>> np.bitwise_and(a1, a2)
array([0, 0, 0, 1], dtype=int32)

And since NumPy (and similarly pandas) does different things for boolean (Boolean or “mask” index arrays) and integer (Index arrays) indices the results of indexing will be also be different:

>>> a3 = np.array([1, 2, 3, 4])

>>> a3[np.logical_and(a1, a2)]
array([4])
>>> a3[np.bitwise_and(a1, a2)]
array([1, 1, 1, 2])

Summary table

Logical operator | NumPy logical function | NumPy bitwise function | Bitwise operator
-------------------------------------------------------------------------------------
       and       |  np.logical_and        | np.bitwise_and         |        &
-------------------------------------------------------------------------------------
       or        |  np.logical_or         | np.bitwise_or          |        |
-------------------------------------------------------------------------------------
                 |  np.logical_xor        | np.bitwise_xor         |        ^
-------------------------------------------------------------------------------------
       not       |  np.logical_not        | np.invert              |        ~

Where the logical operator does not work for NumPy arrays, pandas Series, and pandas DataFrames. The others work on these data structures (and plain Python objects) and work element-wise. However be careful with the bitwise invert on plain Python bools because the bool will be interpreted as integers in this context (for example ~False returns -1 and ~True returns -2).

I saw in getwindowtext (user32) on pinvoke.net that you can place a MarshalAs statement to state that the StringBuffer is equivalent to LPSTR.

<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Ansi)> _
Public Function GetWindowText(hwnd As IntPtr, <MarshalAs(UnManagedType.LPStr)>lpString As System.Text.StringBuilder, cch As Integer) As Integer
End Function

It's worth understanding what those error messages mean - needs merge and error: you need to resolve your current index first indicate that a merge failed, and that there are conflicts in those files. If you've decided that whatever merge you were trying to do was a bad idea after all, you can put things back to normal with:

git reset --merge

However, otherwise you should resolve those merge conflicts, as described in the git manual.

Once you've dealt with that by either technique you should be able to checkout the 9-sign-in-out branch. The problem with just renaming your 9-sign-in-out to master, as suggested in wRAR's answer is that if you've shared your previous master branch with anyone, this will create problems for them, since if the history of the two branches diverged, you'll be publishing rewritten history.

Essentially what you want to do is to merge your topic branch 9-sign-in-out into master but exactly keep the versions of the files in the topic branch. You could do this with the following steps:

# Switch to the topic branch:
git checkout 9-sign-in-out

# Create a merge commit, which looks as if it's merging in from master, but is
# actually discarding everything from the master branch and keeping everything
# from 9-sign-in-out:
git merge -s ours master

# Switch back to the master branch:
git checkout master

# Merge the topic branch into master - this should now be a fast-forward
# that leaves you with master exactly as 9-sign-in-out was:
git merge 9-sign-in-out

Assuming lengths of portfolio and index are the same:

matrix = []
for i in range(len(portfolio)):
    matrix.append([portfolio[i], index[i]])

Or a one-liner using list comprehension:

matrix2 = [[portfolio[i], index[i]] for i in range(len(portfolio))]

$x = get-content $file
$x[1..$x.count] | set-content $file

Just that much. Long boring explanation follows. Get-content returns an array. We can "index into" array variables, as demonstrated in this and other Scripting Guys posts.

For example, if we define an array variable like this,

$array = @("first item","second item","third item")

so $array returns

first item
second item
third item

then we can "index into" that array to retrieve only its 1st element

$array[0]

or only its 2nd

$array[1]

or a range of index values from the 2nd through the last.

$array[1..$array.count]

There is a problem with setting the tint color on the view after presenting; even if you do it in the completion block of presentViewController:animated:completion:, it causes a flicker effect on the color of the button titles. This is sloppy, unprofessional and completely unacceptable.

Other solutions presented depend on the view hierarchy remaining static, something that Apple is loathe to do. Expect those solutions to fail in future releases of iOS.

The one sure-fire way to solve this problem and to do it everywhere, is via adding a category to UIAlertController and swizzling the viewWillAppear.

The header:

//
//  UIAlertController+iOS9TintFix.h
//
//  Created by Flor, Daniel J on 11/2/15.
//

#import <UIKit/UIKit.h>

@interface UIAlertController (iOS9TintFix)

+ (void)tintFix;

- (void)swizzledViewWillAppear:(BOOL)animated;

@end

The implementation:

//
//  UIAlertController+iOS9TintFix.m
//
//  Created by Flor, Daniel J on 11/2/15.
//

#import "UIAlertController+iOS9TintFix.h"
#import <objc/runtime.h>

@implementation UIAlertController (iOS9TintFix)

+ (void)tintFix {
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        Method method  = class_getInstanceMethod(self, @selector(viewWillAppear:));
        Method swizzle = class_getInstanceMethod(self, @selector(swizzledViewWillAppear:));
        method_exchangeImplementations(method, swizzle);});
}

- (void)swizzledViewWillAppear:(BOOL)animated {
    [self swizzledViewWillAppear:animated];
    for (UIView *view in self.view.subviews) {
        if (view.tintColor == self.view.tintColor) {
            //only do those that match the main view, so we don't strip the red-tint from destructive buttons.
            self.view.tintColor = [UIColor colorWithRed:0.0 green:122.0/255.0 blue:1.0 alpha:1.0];
            [view setNeedsDisplay];
        }
    }
}

@end

Add a .pch (precompiled header) to your project and include the category:

#import "UIAlertController+iOS9TintFix.h"

Make sure you register your pch in the project properly, and it will include the category methods in every class that uses the UIAlertController.

Then, in your app delegates didFinishLaunchingWithOptions method, import your category and call

[UIAlertController tintFix];

and it will automatically propagate to every single instance of UIAlertController within your app, whether launched by your code or anyone else's.

This solution works for both iOS 8.X and iOS 9.X and lacks the flicker of the tint change post-presentation approach. It is also completely agnostic with respect to the view hierarchy of the sub-views of the UIAlertController.

Happy hacking!

Javascript is an asynchronous programming language so you can't stop the execution for a of time; the only way you can [pseudo]stop an execution is using setTimeout() that is not a delay but a "delayed function callback".

Recently, I explored the possibilities to parameterize the folder to scan through and the place where the result of recursive scan will be stored. At the end, I also did summarize the number of folders scanned and number of files inside as well. Sharing it with community in case it may help other developers.

I always considered the .hpp header to be a sort of portmanteau of .h and .cpp files...a header which contains implementation details as well.

Typically when I've seen (and use) .hpp as an extension, there is no corresponding .cpp file. As others have said, this isn't a hard and fast rule, just how I tend to use .hpp files.

you must parse JSON string to become object

var dataObject = jQuery.parseJSON(data);

so you can call it like:

success: function (data) {
    var dataObject = jQuery.parseJSON(data);
    if (dataObject.success == 1) {
       var insertedGoalId = dataObject.inserted.goal_id;
       ...
       ...
    }
}

I think this will be much simpler for beginners in JavaScript

    //The function checks if the password and confirm password match
    // Then disables the submit button for mismatch but enables if they match
            function checkPass()
            {
                //Store the password field objects into variables ...
                var pass1 = document.getElementById("register-password");
                var pass2 = document.getElementById("confirm-password");
                //Store the Confimation Message Object ...
                var message = document.getElementById('confirmMessage');
                //Set the colors we will be using ...
                var goodColor = "#66cc66";
                var badColor = "#ff6666";
                //Compare the values in the password field 
                //and the confirmation field
                if(pass1.value == pass2.value){
                    //The passwords match. 
                    //Set the color to the good color and inform
                    //the user that they have entered the correct password 
                    pass2.style.backgroundColor = goodColor;
                    message.style.color = goodColor;

                    var tabPom = document.getElementById("btnSignUp");
                    $(tabPom ).prop('disabled', false);
                }else{
                    //The passwords do not match.
                    //Set the color to the bad color and
                    //notify the user.
                    pass2.style.backgroundColor = badColor;
                    message.style.color = badColor;
                    message.innerHTML = "Passwords Do Not Match!"
 //Disables the submit button when there's mismatch       
                    var tabPom = document.getElementById("btnSignUp");
                    $(tabPom ).prop('disabled', true);
                }
            } 

Well, wish I had read all the other posts so I didn't lose time creating this from Rakesh Pai's answer. Here's a recursive solution that works with arrays and objects. No dependency on jQuery.

Added a segment to handle cases where the entire form should be submitted like an array. (ie. where there's no wrapper object around a list of items)

/**
 * Posts javascript data to a url using form.submit().  
 * Note: Handles json and arrays.
 * @param {string} path - url where the data should be sent.
 * @param {string} data - data as javascript object (JSON).
 * @param {object} options -- optional attributes
 *  { 
 *    {string} method: get/post/put/etc,
 *    {string} arrayName: name to post arraylike data.  Only necessary when root data object is an array.
 *  }
 * @example postToUrl('/UpdateUser', {Order {Id: 1, FirstName: 'Sally'}});
 */
function postToUrl(path, data, options) {
    if (options === undefined) {
        options = {};
    }

    var method = options.method || "post"; // Set method to post by default if not specified.

    var form = document.createElement("form");
    form.setAttribute("method", method);
    form.setAttribute("action", path);

    function constructElements(item, parentString) {
        for (var key in item) {
            if (item.hasOwnProperty(key) && item[key] != null) {
                if (Object.prototype.toString.call(item[key]) === '[object Array]') {
                    for (var i = 0; i < item[key].length; i++) {
                        constructElements(item[key][i], parentString + key + "[" + i + "].");
                    }
                } else if (Object.prototype.toString.call(item[key]) === '[object Object]') {
                    constructElements(item[key], parentString + key + ".");
                } else {
                    var hiddenField = document.createElement("input");
                    hiddenField.setAttribute("type", "hidden");
                    hiddenField.setAttribute("name", parentString + key);
                    hiddenField.setAttribute("value", item[key]);
                    form.appendChild(hiddenField);
                }
            }
        }
    }

    //if the parent 'data' object is an array we need to treat it a little differently
    if (Object.prototype.toString.call(data) === '[object Array]') {
        if (options.arrayName === undefined) console.warn("Posting array-type to url will doubtfully work without an arrayName defined in options.");
        //loop through each array item at the parent level
        for (var i = 0; i < data.length; i++) {
            constructElements(data[i], (options.arrayName || "") + "[" + i + "].");
        }
    } else {
        //otherwise treat it normally
        constructElements(data, "");
    }

    document.body.appendChild(form);
    form.submit();
};

Use the library EventBus to pass event that could contain your variable back and forth. It's a good solution because it keeps your activities and fragments loosely coupled

$("#y").load("x.html");

Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

The MDN Documentation is very eloquent and features examples.

The API Guide has it all wrong (really Google?). With Maps API v2 you do not need to enable a layer to show yourself, there is a simple call to the GoogleMaps instance you created with your map.

Google Documentation

The actual documentation that Google provides gives you your answer. You just need to

If you are using Kotlin

// map is a GoogleMap object
map.isMyLocationEnabled = true

If you are using Java

// map is a GoogleMap object
map.setMyLocationEnabled(true);

and watch the magic happen.

Just make sure that you have location permission and requested it at runtime on API Level 23 (M) or above

Basically the .htaccess file should exists and the httpd.conf should be correct.

In my case, I changed the file /etc/apache2/apache2.conf in section:

<Directory "/var/www/html">

Line changed is:

AllowOverride None

to

AllowOverride All

And restart the web server with

systemctl restart apache2

You can bind a click handler that returns false:

$('.my-link').click(function () {return false;});

To re-enable it again, unbind the handler:

$('.my-link').unbind('click');

Note that disabled doesn't work because it is designed for form inputs only.

jQuery has anticipated this already, providing a shortcut as of jQuery 1.4.3:

$('.my-link').bind('click', false);

And to unbind / re-enable:

$('.my-link').unbind('click', false);

There is no need for using NSAttributedString. All you need is a simple label with the proper textColor. Plus this simple solution will work with all versions of iOS, not just iOS 6.

But if you needlessly wish to use NSAttributedString, you can do something like this:

UIColor *color = [UIColor redColor]; // select needed color
NSString *string = ... // the string to colorize
NSDictionary *attrs = @{ NSForegroundColorAttributeName : color };
NSAttributedString *attrStr = [[NSAttributedString alloc] initWithString:string attributes:attrs];
self.scanLabel.attributedText = attrStr;

The selector would be label[for=email], so in CSS:

label[for=email]
{
    /* ...definitions here... */
}

...or in JavaScript using the DOM:

var element = document.querySelector("label[for=email]");

...or in JavaScript using jQuery:

var element = $("label[for=email]");

It's an attribute selector. Note that some browsers (versions of IE < 8, for instance) may not support attribute selectors, but more recent ones do. To support older browsers like IE6 and IE7, you'd have to use a class (well, or some other structural way), sadly.

(I'm assuming that the template {t _your_email} will fill in a field with id="email". If not, use a class instead.)

Note that if the value of the attribute you're selecting doesn't fit the rules for a CSS identifier (for instance, if it has spaces or brackets in it, or starts with a digit, etc.), you need quotes around the value:

label[for="field[]"]
{
    /* ...definitions here... */
}

They can be single or double quotes.

// in foo.h
class Foo {
    static const unsigned char* Msg;
};

// in foo.cpp
static const unsigned char Foo_Msg_data[] = {0x00,0x01};
const unsigned char* Foo::Msg = Foo_Msg_data;

The .css() function doesn't queue behind running animations, it's instantaneous.

To match the behaviour that you're after, you'd need to do the following:

$(document).ready(function() {
  $("button").mouseover(function() {
    var p = $("p#44.test").css("background-color", "yellow");
    p.hide(1500).show(1500);
    p.queue(function() {
      p.css("background-color", "red");
    });
  });
});

The .queue() function waits for running animations to run out and then fires whatever's in the supplied function.

All you need is System.Environment.Exit(1);

And it uses the system namespace "using System" that's pretty much always there when you start a project.

IFNULL, see here: http://www.sqlite.org/lang_corefunc.html#ifnull

no brackets around the function

Try playing around with the following css rule:

#content {
    min-height: 600px;
    height: auto !important;
    height: 600px;
}

Change the height to suit your page. height is mentioned twice for cross browser compatibility.

1- All you have to do is set the selection style on the UITableViewCell instance using either:

Objective-C:

cell.selectionStyle = UITableViewCellSelectionStyleNone;

or

[cell setSelectionStyle:UITableViewCellSelectionStyleNone];

Swift 2:

cell.selectionStyle = UITableViewCellSelectionStyle.None

Swift 3:

cell.selectionStyle = .none

2 - Don't implement -tableView:didSelectRowAtIndexPath: in your table view delegate or explicitly exclude the cells you want to have no action if you do implement it.

3 - Further,You can also do it from the storyboard. Click the table view cell and in the attributes inspector under Table View Cell, change the drop down next to Selection to None.

4 - You can disable table cell highlight using below code in (iOS) Xcode 9 , Swift 4.0

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


        let cell = tableView.dequeueReusableCell(withIdentifier: "OpenTbCell") as! OpenTbCell
        cell.selectionStyle = .none
        return cell


}

I wasn't having any luck with the above answers (including --flat), but what worked for me was:

cd path/to/specific/directory

From there, I ran the ng g c mynewcomponent

None of the above answers worked for me, but I got it working with the following:

src="'https://maps.google.com/maps?q=' + lat + ',' + long + '&t=&z=15&ie=UTF8&iwloc=&output=embed'"

I consider state to be for view only information and data that should persist beyond the view state is better stored as props. URL params are useful when you want to be able to link to a page or share the URL deep in to the app but otherwise clutter the address bar.

Take a look at Redux-Persist (if you're using redux) https://github.com/rt2zz/redux-persist

public class MainActivity extends AppCompatActivity {

    Button button;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        button = findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                openURL("http://docs.google.com/viewer?url=" + " your pdf link ");
            }
        });
    }

    private void openURL(String s) {
        Uri uri = Uri.parse(s);
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setDataAndType(uri,"text/html");
        startActivity(intent);
    }
}

public func jsonPrint(_ o: NSObject, spacing: String = "", after: String = "", before: String = "") {
    let newSpacing = spacing + "    "
    if o.isArray() {
        print(before + "[")
        if let a = o as? Array<NSObject> {
            for object in a {
                jsonPrint(object, spacing: newSpacing, after: object == a.last! ? "" : ",", before: newSpacing)
            }
        }
        print(spacing + "]" + after)
    } else {
        if o.isDictionary() {
            print(before + "{")
            if let a = o as? Dictionary<NSObject, NSObject> {
                for (key, val) in a {
                    jsonPrint(val, spacing: newSpacing, after: ",", before: newSpacing + key.description + " = ")
                }
            }
            print(spacing + "}" + after)
        } else {
            print(before + o.description + after)
        }
    }
}

This one is pretty close to original Objective-C print style

I'll have to add an answer here, because the other answers are either not covering my case or are needlessly complicated. I use github with other developers and I just want all the local branches whose remotes were (possibly merged and) deleted from a github PR to be deleted in one go from my machine. No, things like git branch -r --merged don't cover the branches that were not merged locally, or the ones that were not merged at all (abandoned) etc, so a different solution is needed.

Anyway, the first step I got it from other answers:

git fetch --prune

A dry run of git remote prune origin seemed like it would do the same thing in my case, so I went with the shortest version to keep it simple.

Now, a git branch -v should mark the branches whose remotes are deleted as [gone]. Therefore, all I need to do is:

git branch -v|grep \\[gone\\]|awk '{print $1}'|xargs -I{} git branch -D {}

As simple as that, it deletes everything I want for the above scenario.

The less common xargs syntax is so that it also works on Mac & BSD in addition to Linux. Careful, this command is not a dry run so it will force-delete all the branches marked as [gone]. Obviously, this being git nothing is gone forever, if you see branches deleted that you remember you wanted kept you can always undelete them (the above command will have listed their hash on deletion, so a simple git checkout -b <branch> <hash>.

Edit: Just add this alias to your .bashrc/.bash_profile, the two commands made into one and I updated the second to work on all shells:

alias old_branch_delete='git fetch -p && git branch -vv | awk "/: gone]/{print \$1}" | xargs git branch -D'

I'm back to Windows for the first time in a long time and this got me cursing like a docker. I finally found this:

Enabling Ctrl+Shift+letter shortcuts got me to a Linux-like behaviour that has lowered my blood pressure. Ctrl+Shift+C/Vnow works.

jQuery does not have a method for comparing arrays. However the Underscore library (or the comparable Lodash library) does have such a method: isEqual, and it can handle a variety of other cases (like object literals) as well. To stick to the provided example:

var a=[1,2,3];
var b=[3,2,1];
var c=new Array(1,2,3);

alert(_.isEqual(a, b) + "|" + _.isEqual(b, c));

By the way: Underscore has lots of other methods that jQuery is missing as well, so it's a great complement to jQuery.

EDIT: As has been pointed out in the comments, the above now only works if both arrays have their elements in the same order, ie.:

_.isEqual([1,2,3], [1,2,3]); // true
_.isEqual([1,2,3], [3,2,1]); // false

Fortunately Javascript has a built in method for for solving this exact problem, sort:

_.isEqual([1,2,3].sort(), [3,2,1].sort()); // true

Although this is not supported by all browsers, if you use capturing parentheses inside your regular expression then the captured input is spliced into the result.

If separator is a regular expression that contains capturing parentheses, then each time separator is matched, the results (including any undefined results) of the capturing parentheses are spliced into the output array. [reference)

So:

var stringArray = str.split(/(\s+)/);
                             ^   ^
//

Output:

["my", " ", "car", " ", "is", " ", "red"]

This collapses consecutive spaces in the original input, but otherwise I can't think of any pitfalls.

A simple hack is to add username and password to the push url in your project's .hg/hgrc file:

[paths]
default = http://username:[email protected]/myproject

(Note that in this way you store the password in plain text)

If you're working on several projects under the same domain, you might want to add a rewrite rule in your ~/.hgrc file, to avoid repeating this for all projects:

[rewrite]
http.//mydomain.com = http://username:[email protected]

Again, since the password is stored in plain text, I usually store just my username.

If you're working under Gnome, I explain how to integrate Mercurial and the Gnome Keyring here:

http://aloiroberto.wordpress.com/2009/09/16/mercurial-gnome-keyring-integration/

if you dont push your changes to git yet

git reset --soft HEAD~1

It will reset all the changes and revert to one commit back

If this is the last commit you made and you want to delete the file from local and remote repository try this :

git rm <file>
 git commit --amend

or even better :

reset first

git reset --soft HEAD~1

reset the unwanted file

git reset HEAD path/to/unwanted_file

commit again

git commit -c ORIG_HEAD  

You could:

• Define a userStatus parameter for the child component and provide the value when using this component from the parent:

  @Component({
    (...)
  })
  export class Profile implements OnInit {
    @Input()
    userStatus:UserStatus;
  
    (...)
  }
  

  and in the parent:

  <profile [userStatus]="userStatus"></profile>
  

• Inject the parent into the child component:

  @Component({
    (...)
  })
  export class Profile implements OnInit {
    constructor(app:App) {
      this.userStatus = app.userStatus;
    }
  
    (...)
  }
  

  Be careful about cyclic dependencies between them.

Here is the jQuery function I use:

function isExists(var elemId){
    return jQuery('#'+elemId).length > 0;
}

This will return a boolean value. If element exists, it returns true. If you want to select element by class name, just replace # with .

Running the @neverever415 answer I got:

Failure [DELETE_FAILED_INTERNAL_ERROR]

In this case check that you wrote a right package name, maybe it is a debug version like com.package_name.debug:

adb shell pm uninstall com.package_name.debug

Or see https://android.stackexchange.com/questions/179575/how-to-uninstall-a-system-app-using-adb-uninstall-command-not-remove-via-rm-or.

I had the exact same issue on my branch(lets call it branch B) and I followed three simple steps to get make it work

1. Switched to the master branch (git checkout master)
2. Did a pull on the master (git pull)
3. Created new branch (git branch C) - note here that we are now branching from master
4. Now when you are on branch C, merge with branch B (git merge B)
5. Now do a push (git push origin C) - works :)

Now you can delete branch B and then rename branch C to branch B.

Hope this helps.

Since you have jQuery on the page, you can remove that onclick attribute and the majorpointsexpand function. Add the following script to the bottom of you page or, preferably, to an external .js file:

$(function(){

  $('.majorpointslegend').click(function(){
    $(this).next().toggle().text( $(this).is(':visible')?'Collapse':'Expand' );
  });

});

This solutionshould work with your HTML as is but it isn't really a very robust answer. If you change your fieldset layout, it could break it. I'd suggest that you put a class attribute in that hidden div, like class="majorpointsdetail" and use this code instead:

$(function(){

  $('.majorpoints').on('click', '.majorpointslegend', function(event){
    $(event.currentTarget).find('.majorpointsdetail').toggle();
    $(this).text( $(this).is(':visible')?'Collapse':'Expand' );
  });

});

Obs: there's no closing </fieldset> tag in your question so I'm assuming the hidden div is inside the fieldset.

With a little bit correcting @Jolly1234's Answer: here is the code:

raw_string=path.encode('unicode_escape').decode()

If you have a Decimal or similar numeric type, you can use:

Math.Round(myNumber, 2)

EDIT: So, in your case, it would be:

Public Class Form1
  Private Sub btncalc_Click(ByVal sender As System.Object,
                            ByVal e As System.EventArgs) Handles btncalc.Click
    txtA.Text = Math.Round((Val(txtD.Text) / Val(txtC.Text) * Val(txtF.Text) / Val(txtE.Text)), 2)
    txtB.Text = Math.Round((Val(txtA.Text) * 1000 / Val(txtG.Text)), 2)
  End Sub
End Class

$('div.alldivs :first-child');

Or you can just refer to the id directly:

$('#div1');

As suggested, you might be better of using the child selector:

$('div.alldivs > div:first-child')

If you dont have to use first-child, you could use :first as also suggested, or $('div.alldivs').children(0).

I use this

var e = document.getElementById('ticket_category_clone').value;

Notice that you don't need the '#' character in javascript.

    function check () {

    var str = document.getElementById('ticket_category_clone').value;

      if (str==="Hardware")
      {
        SPICEWORKS.utils.addStyle('#ticket_c_hardware_clone{display: none !important;}');
      }

    }

SPICEWORKS.app.helpdesk.ready(check);?

Check for a value single level

const hasValue = Object.values(json).includes("bar");

Check for a value multi-level

function hasValueDeep(json, findValue) {
    const values = Object.values(json);
    let hasValue = values.includes(findValue);
    values.forEach(function(value) {
        if (typeof value === "object") {
            hasValue = hasValue || hasValueDeep(value, findValue);
        }
    })
    return hasValue;
}

The secret is you need to copy msvcr100.dll to the path where the installation says msvcr100.dll is missing (dialog box) and then try to install the sql developer.

For me I had to create bin folder in

C:\sqldeveloper\jdk\bin

and Copy msvcr100.dll to it.

If still not working! Try this!

You might also need to change the config file settings found in

C:\sqldeveloper\sqldeveloper\bin

Download and install 32 bit JDK (Windows) and set the path in config file as

SetJavaHome C:/Program Files (x86)/Java/jdk1.7.0_01

SET @customerID=0;
SELECT @customerID:=@customerID+1 AS customerID
FROM CUSTOMER ;

you can obtain the dataset from SQL like this and populate it into a java data structure (like a List) and then make the necessary sorting over there. (maybe with the help of a comparable interface)

And even simpler using IN:

SELECT ads.*, location.county 
  FROM ads
  LEFT JOIN location ON location.county = ads.county_id
  WHERE ads.published = 1 
        AND ads.type = 13
        AND ads.county_id IN (2,5,7,9)

You can use MATCH for instance.

1. Select the column from the first cell, for example cell A2 to cell A100 and insert a conditional formatting, using 'New Rule...' and the option to conditional format based on a formula.

2. In the entry box, put:

   =MATCH(A2, 'Sheet2'!A:A, 0)
   

3. Pick the desired formatting (change the font to red or fill the cell background, etc) and click OK.

MATCH takes the value A2 from your data table, looks into 'Sheet2'!A:A and if there's an exact match (that's why there's a 0 at the end), then it'll return the row number.

Note: Conditional formatting based on conditions from other sheets is available only on Excel 2010 onwards. If you're working on an earlier version, you might want to get the list of 'Don't check' in the same sheet.

EDIT: As per new information, you will have to use some reverse matching. Instead of the above formula, try:

=SUM(IFERROR(SEARCH('Sheet2'!$A$1:$A$44, A2),0))

If you don't want line numbers shown all the time another way to find the line number of a piece of code is to just click in the left-most margin and create a breakpoint (a small blue arrow appears) then go to the breakpoint navigator (?7) where it will list the breakpoint with its line number. You can delete the breakpoint by right clicking on it.

You might want to check out Remy Sharp's recent article on fixed floating elements at jQuery for Designers, which has a nice video and writeup on how to apply this effect in client script

def  lst = ["A2", "A1", "k22", "A6", "a3", "a5", "A4", "A7"]; 

println lst.sort { a, b -> a.compareToIgnoreCase b }

This should be able to sort with case insensitive but I am not sure how to tackle the alphanumeric strings lists

I have also just solved the coresponding exercise on codeacademy and wanted to compare my approach to others. I have not found the solution I used so far, so I thought that I sign up here and provide my solution to others. And maybe I get a suggestion or a helpful comment on how to improve the code.

Ok here it goes, I did not use any list to store the string, instead I have just accessed the string index. It took me a bit at first to deal with the len() and index number, but in the end it worked :).

def reverse(x):
reversestring = ""
for n in range(len(str(x))-1,-1, -1):
    reversestring += x[n]
return reversestring 

I am still wondering if the reversestring = "" could be solved in a more elegant way, or if it is "bad style" even, but i couldn't find an answer so far.

If you change the format of the cells to General then this will show the date value of a cell as behind the scenes Excel saves a date as the number of days since 01/01/1900

If your date is text and you need to convert it then DATEVALUE will do this:

Try this:

str.replace("\"", "\\\""); // (Escape backslashes and embedded double-quotes)

Or, use single-quotes to quote your search and replace strings:

str.replace('"', '\\"');   // (Still need to escape the backslash)

As pointed out by helmus, if the first parameter passed to .replace() is a string it will only replace the first occurrence. To replace globally, you have to pass a regex with the g (global) flag:

str.replace(/"/g, "\\\"");
// or
str.replace(/"/g, '\\"');

But why are you even doing this in JavaScript? It's OK to use these escape characters if you have a string literal like:

var str = "Dude, he totally said that \"You Rock!\"";

But this is necessary only in a string literal. That is, if your JavaScript variable is set to a value that a user typed in a form field you don't need to this escaping.

Regarding your question about storing such a string in an SQL database, again you only need to escape the characters if you're embedding a string literal in your SQL statement - and remember that the escape characters that apply in SQL aren't (usually) the same as for JavaScript. You'd do any SQL-related escaping server-side.

Alternatively:

public static T Cast<T>(this dynamic obj) where T:class
{
   return obj as T;
}

Change the file name if your file name is like pandas.py or pd.py, it will shadow the real name otherwise.

You have two boxes, left and right, for each label/input pair. Both boxes are in one row and have fixed width. Now, you just have to make label text float to the right with text-align: right;

Here's a simple example:

This is the modern way of reloading a module:

from importlib import reload

If you want to support versions of Python older than 3.5, try this:

from sys import version_info
if version_info[0] < 3:
    pass # Python 2 has built in reload
elif version_info[0] == 3 and version_info[1] <= 4:
    from imp import reload # Python 3.0 - 3.4 
else:
    from importlib import reload # Python 3.5+

To use it, run reload(MODULE), replacing MODULE with the module you want to reload.

For example, reload(math) will reload the math module.

I used the properties plugin to solve this.

Properties are defined in the pom, and written out to a my.properties file, where they can then be accessed from your Java code.

In my case it is test code that needs to access this properties file, so in the pom the properties file is written to maven's testOutputDirectory:

<configuration>
    <outputFile>${project.build.testOutputDirectory}/my.properties</outputFile>
</configuration>

Use outputDirectory if you want properties to be accessible by your app code:

<configuration>
    <outputFile>${project.build.outputDirectory}/my.properties</outputFile>
</configuration>

For those looking for a fuller example (it took me a bit of fiddling to get this working as I didn't understand how naming of properties tags affects ability to retrieve them elsewhere in the pom file), my pom looks as follows:

<dependencies>
     <dependency>
      ...
     </dependency>
</dependencies>

<properties>
    <app.env>${app.env}</app.env>
    <app.port>${app.port}</app.port>
    <app.domain>${app.domain}</app.domain>
</properties>

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.20</version>
        </plugin>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>properties-maven-plugin</artifactId>
            <version>1.0.0</version>
            <executions>
                <execution>
                    <phase>generate-resources</phase>
                    <goals>
                        <goal>write-project-properties</goal>
                    </goals>
                    <configuration>
                        <outputFile>${project.build.testOutputDirectory}/my.properties</outputFile>
                    </configuration>
                </execution>
            </executions>
        </plugin>

    </plugins>
</build>

And on the command line:

mvn clean test -Dapp.env=LOCAL -Dapp.domain=localhost -Dapp.port=9901

So these properties can be accessed from the Java code:

 java.io.InputStream inputStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("my.properties");
 java.util.Properties properties = new Properties();
 properties.load(inputStream);
 appPort = properties.getProperty("app.port");
 appDomain = properties.getProperty("app.domain");

JSON is valid JavaScript Object anyway, while you are printing JavaScript itself, you don't need to encode/decode JSON further once it is converted to JSON.

<script type="text/javascript">
    var addresses = @Html.Raw(Model.Addresses);
</script>

Following will be printed, and it is valid JavaScript Expression.

<script type="text/javascript">
    var addresses = [["123 Street St.","City","CA","12345"],["456 Street St.","City","UT","12345"],["789 Street St.","City","OR","12345"]];
</script>

I have made my own implementation to do this on the simplest way as possible.

I like to work with this implementation, but another possible good way, it's don't make the AbstractSystemServiceTask class abstract, and build it through a Builder.

I hope it help you.

I have tried all suggestions and found my own simple solution.

The problem is that codes written in external environment like C need compiler. Look for its own VS environment, i.e. VS 2008.

Currently my machine runs VS 2012 and faces Unable to find vcvarsall.bat. I studied codes that i want to install to find the VS version. It was VS 2008. i have add to system variable VS90COMNTOOLS as variable name and gave the value of VS120COMNTOOLS.

You can find my step by step solution below:

1. Right click on My Computer.
2. Click Properties
3. Advanced system settings
4. Environment variables
5. Add New system variable
6. Enter VS90COMNTOOLS to the variable name
7. Enter the value of current version to the new variable.
8. Close all windows

Now open a new session and pip install your-package

The essential thing about abstraction is that client code operates in terms of a different logical/abstract model. That different model may be more or less complex than the implementation happens to be in any given client usage.

For example, "Iterator" abstracts (aka generalises) sequenced traversal of 0 or more values - in C++ it manifests as begin(), */-> (dereferencing), end(), pre/post ++ and possibly --, then there's +, +=, [], std::advance etc.. That's a lot of baggage if the client could say increment a size_t along an array anyway. The essential thing is that the abstraction allows client code that needs to perform such a traversal to be decoupled from the exact nature of the "container" or data source providing the elements. Iteration is a higher-level notion that sometimes restricts the way the traversal is performed (e.g. a forward iterator can only advance an element at a time), but the data can then be provided by a larger set of sources (e.g. from a keyboard where there's not even a "container" in the sense of concurrently stored values). The client code can generally switch to another data source abstracted through its own iterators with minimal or even no changes, and even polymorphically to other data types - either implicitly or explicitly using something like std::iterator_traits<Iterator>::value_type available.

This is quite a different thing from encapsulation, which is the practice of making some data or functions less accessible, such that you know they're only used indirectly as a result of operations on the public interface. Encapsulation is an essential tool for maintaining invariants on an object, which means things you want to keep true after every public operation - if client code could just reach in and modify your object then you can't enforce any invariants. For example, a class might wrap a string, ensuring that after any operation any lowercase letters were changed to upper case, but if the client code can reach in and put a lowercase letter into the string without the involvement of the class's member functions, then the invariant can't be enforced.

To further highlight the difference, consider say a private std::vector<Timing_Sample> data member that's incidentally populated by operations on the containing object, with a report dumped out on destruction. With the data and destructor side effect not interacting with the object's client code in any way, and the operations on the object not intentionally controlling the time-keeping behaviour, there's no abstraction of that time reporting functionality but there is encapsulation. An example of abstraction would be to move the timing code into a separate class that might encapsulate the vector (make it private) and just provide a interface like add(const Timing_Sample&) and report(std::ostream&) - the necessary logical/abstract operations involved with using such instrumentation, with the highly desirable side effect that the abstracted code will often be reusable for other client code with similar functional needs.

This gives you the root folder:

System.AppDomain.CurrentDomain.BaseDirectory

You can navigate from here using .. or ./ etc.. , Appending .. takes you to folder where .sln file can be found

For .NET framework (thanks to Adiono comment)

Path.GetFullPath(Path.Combine(AppDomain.CurrentDomain.BaseDirectory,"..\\..\\"))

For .NET core here is a way to do it (thanks to nopara73 comment)

Path.GetFullPath(Path.Combine(AppContext.BaseDirectory, "..\\..\\..\\")) ;

The example you are using is wrong. See the man page for easy_setopt. In the example write_data uses its own FILE, *outfile, and not the fp that was specified in CURLOPT_WRITEDATA. That's why closing fp causes problems - it's not even opened.

This is more or less what it should look like (no libcurl available here to test)

#include <stdio.h>
#include <curl/curl.h>
/* For older cURL versions you will also need 
#include <curl/types.h>
#include <curl/easy.h>
*/
#include <string>

size_t write_data(void *ptr, size_t size, size_t nmemb, FILE *stream) {
    size_t written = fwrite(ptr, size, nmemb, stream);
    return written;
}

int main(void) {
    CURL *curl;
    FILE *fp;
    CURLcode res;
    char *url = "http://localhost/aaa.txt";
    char outfilename[FILENAME_MAX] = "C:\\bbb.txt";
    curl = curl_easy_init();
    if (curl) {
        fp = fopen(outfilename,"wb");
        curl_easy_setopt(curl, CURLOPT_URL, url);
        curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_data);
        curl_easy_setopt(curl, CURLOPT_WRITEDATA, fp);
        res = curl_easy_perform(curl);
        /* always cleanup */
        curl_easy_cleanup(curl);
        fclose(fp);
    }
    return 0;
}

Updated: as suggested by @rsethc types.h and easy.h aren't present in current cURL versions anymore.

Similarly to making your PC a wireless access point, but can be much easier, is using reverse tethering. If you happen to have an HTC phone they have a nice reverse-tethering option called "Internet pass-through", under the network/mobile network sharing settings. It routes all your traffic through your PC and you can just run Wireshark there.

You have to put div with single quotation around it. ' ' the Div must be in the middle of single quotation . i'm gonna clear it with one example :

<?php
        echo '<div id="output">'."Identify".'<br>'.'<br>';
        echo 'Welcome '."$name";
        echo "<br>";
        echo 'Web Mail: '."$email";
        echo "<br>";
        echo 'Department of '."$dep";
        echo "<br>";
        echo "$maj";
        '</div>'
?>

hope be useful.

Here are some useful links:

The 2nd column is the keyCode and the html column shows how it will displayed. You can test it here.

Wireshark, Firebug, Fiddler all do similar things - capture network traffic.

• Wireshark captures any kind of network packet. It can capture packet details below TCP/IP (HTTP is at the top). It does have filters to reduce the noise it captures.

• Firebug tracks each request the browser page makes and captures the associated headers and the time taken for each stage of the request (DNS, receiving, sending, ...).

• Fiddler works as an HTTP/HTTPS proxy. It captures every HTTP request the computer makes and records everything associated with it. It does allow things like converting post variables to a table form and editing/replaying requests. It doesn't, by default, capture localhost traffic in IE, see the FAQ for the workaround.

Most Secure Solution, JS only

As mentioned by alko989, there is a major security flaw with _blank (details here).

To avoid it from pure JS code:

const openInNewTab = (url) => {
  const newWindow = window.open(url, '_blank', 'noopener,noreferrer')
  if (newWindow) newWindow.opener = null
}

Then add to your onClick

onClick={() => openInNewTab('https://stackoverflow.com')}

The third param can also take these optional values, based on your needs.

In Java a class can implement an interface. See http://en.wikipedia.org/wiki/Interface_(Java) for more details. Not sure about PHP.

Hope this helps.

The method used for all previous answers to this question suggest changing the url which is not necessary, and I think readers should be aware of an alternative solution. I use ui-router and $stateProvider to associate a state value with a templateUrl which points to the html file for your view. Then it is just a matter of injecting the $state into your controller and calling $state.go('state-value') to update your view.

What is the difference between angular-route and angular-ui-router?

Updating Nuget packages fixed proglem for me.

##Unique Approach

##App.getRes().getString(R.string.some_id)

This will work everywhere in app. (Util class, Dialog, Fragment or any class in your app)

(1) Create or Edit (if already exist) your Application class.

import android.app.Application;
import android.content.res.Resources;

public class App extends Application {
    private static App mInstance;
    private static Resources res;


    @Override
    public void onCreate() {
        super.onCreate();
        mInstance = this;
        res = getResources();
    }

    public static App getInstance() {
        return mInstance;
    }

    public static Resources getRes() {
        return res;
    }

}

(2) Add name field to your manifest.xml <application tag.

<application
        android:name=".App"
        ...
        >
        ...
    </application>

Now you are good to go. Use App.getRes().getString(R.string.some_id) anywhere in app.

You appear to have a heredoc containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF

or if BUILDING is $2 in your script:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF

If your file.sql had an exit at the end then it would be even simpler as you wouldn't need the heredoc:

sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2

In your SQL you can then refer to the position parameters using substitution variables:

...
}',SEM_Models('&1'),NULL,
...

The &1 will be replaced with the first value passed to the SQL script, BUILDING; because that is a string it still needs to be enclosed in quotes. You might want to set verify off to stop if showing you the substitutions in the output.

You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1, the second is &2, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF

or:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF

If total_count is being passed to your shell script then just use its positional parameter, $4 or whatever. And your SQL would then be:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:

define MY_ALIAS = &1
define MY_MODEL = &2

SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

From your separate question, maybe you just wanted:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

... so the alias will be the same value you're querying on (the value in $2, or BUILDING in the original part of the answer). You can refer to a substitution variable as many times as you want.

That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:

select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT

If you set pages 0 and set heading off, your repeated calls might appear in a neat list. You might also need to set tab off and possibly use rpad('&1', 20) or similar to make that column always the same width. Or get the results as CSV with:

select '&1' ||','|| COUNT(*)

Depends what you're using the results for...

Another way to define a 2-d vector is to declare a vector of pair's.

 vector < pair<int,int> > v;

**To insert values**
 cin >> x >>y;
 v.push_back(make_pair(x,y));

**Retrieve Values**
 i=0 to size(v)
 x=v[i].first;
 y=v[i].second;

For 3-d vectors take a look at tuple and make_tuple.

This method checks if a String contains a special character (based on your definition).

/**
 *  Returns true if s contains any character other than 
 *  letters, numbers, or spaces.  Returns false otherwise.
 */

public boolean containsSpecialCharacter(String s) {
    return (s == null) ? false : s.matches("[^A-Za-z0-9 ]");
}

You can use the same logic to count special characters in a string like this:

/**
 *  Counts the number of special characters in s.
 */

 public int getSpecialCharacterCount(String s) {
     if (s == null || s.trim().isEmpty()) {
         return 0;
     }
     int theCount = 0;
     for (int i = 0; i < s.length(); i++) {
         if (s.substring(i, 1).matches("[^A-Za-z0-9 ]")) {
             theCount++;
         }
     }
     return theCount;
 }

Another approach is to put all the special chars in a String and use String.contains:

/**
 *  Counts the number of special characters in s.
 */

 public int getSpecialCharacterCount(String s) {
     if (s == null || s.trim().isEmpty()) {
         return 0;
     }
     int theCount = 0;
     String specialChars = "/*!@#$%^&*()\"{}_[]|\\?/<>,.";
     for (int i = 0; i < s.length(); i++) {
         if (specialChars.contains(s.substring(i, 1))) {
             theCount++;
         }
     }
     return theCount;
 }

NOTE: You must escape the backslash and " character with a backslashes.

The above are examples of how to approach this problem in general.

For your exact problem as stated in the question, the answer by @LanguagesNamedAfterCoffee is the most efficient approach.

list is mutable

Change

last_list=last_list.append(p.last_name)

to

last_list.append(p.last_name)

will work

As a small note, it only started to work for me when I changed smtp to smtps in the examples above per samples from javamail (see smtpsend.java, https://github.com/javaee/javamail/releases/download/JAVAMAIL-1_6_2/javamail-samples.zip, option -S).

My resulting code is as follow:

Properties props=new Properties();
props.put("mail.smtps.starttls.enable","true");
// Use the following if you need SSL
props.put("mail.smtps.socketFactory.port", port);
props.put("mail.smtps.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtps.socketFactory.fallback", "false");
props.put("mail.smtps.host", serverList.get(randNum));
Session session = Session.getDefaultInstance(props);

smtpConnectionPool = new SmtpConnectionPool(
    SmtpConnectionFactories.newSmtpFactory(session));
    
final ClosableSmtpConnection transport = smtpConnectionPool.borrowObject();
...
transport.sendMessage(message, message.getAllRecipients());

Be aware with Unique count you are using 'cardinality' metric, which does not always guarantee exact unique count. :-)

the cardinality metric is an approximate algorithm. It is based on the HyperLogLog++ (HLL) algorithm. HLL works by hashing your input and using the bits from the hash to make probabilistic estimations on the cardinality.

Depending on amount of data I can get differences of 700+ entries missing in a 300k dataset via Unique Count in Elastic which are otherwise really unique.

Read more here: https://www.elastic.co/guide/en/elasticsearch/guide/current/cardinality.html

The file /Applications/MAMP/bin/mamp/mamp.conf.json holds the MAMP configuration, look for the section:

{
  "name": "PHP",
  "version": "5.6.28, 7.0.20"
}

which lists the the php versions which will be displayed in the GUI, obviously you need to have downloaded the PHP version from the MAMP site first and placed it in /Applications/MAMP/bin/php for this to work.

I was handling a bigint datatype to be shown in a DataGridView and made it like this

something = (int)(Int64)data_reader[0];

Here's your example in the "one" line.

this.$OuterDiv = $('<div></div>')
    .hide()
    .append($('<table></table>')
        .attr({ cellSpacing : 0 })
        .addClass("text")
    )
;

Update: I thought I'd update this post since it still gets quite a bit of traffic. In the comments below there's some discussion about $("<div>") vs $("<div></div>") vs $(document.createElement('div')) as a way of creating new elements, and which is "best".

I put together a small benchmark, and here are roughly the results of repeating the above options 100,000 times:

jQuery 1.4, 1.5, 1.6

               Chrome 11  Firefox 4   IE9
<div>            440ms      640ms    460ms
<div></div>      420ms      650ms    480ms
createElement    100ms      180ms    300ms

jQuery 1.3

                Chrome 11
<div>             770ms
<div></div>      3800ms
createElement     100ms

jQuery 1.2

                Chrome 11
<div>            3500ms
<div></div>      3500ms
createElement     100ms

I think it's no big surprise, but document.createElement is the fastest method. Of course, before you go off and start refactoring your entire codebase, remember that the differences we're talking about here (in all but the archaic versions of jQuery) equate to about an extra 3 milliseconds per thousand elements.

Update 2

Updated for jQuery 1.7.2 and put the benchmark on JSBen.ch which is probably a bit more scientific than my primitive benchmarks, plus it can be crowdsourced now!

http://jsben.ch/#/ARUtz

In general, one doesn't expand out log(a + b); you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:

log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)

(In fact, this identity is often used when implementing log in math libraries).

You can use values_list alongside filter like so;

active_emps_first_name = Employees.objects.filter(active=True).values_list('first_name',flat=True)

Removing Read-only CheckBox from C:\Users\SQL Service account name\AppData\Local\Temp worked for me.

You can add

DBQuery.prototype._prettyShell = true

to your file in $HOME/.mongorc.js to enable pretty print globally by default.

As with modern browser, placeholder is supported by new version of Chrome / Firefox, similar as the C style function printf().

Placeholders:

• %s String.
• %d,%i Integer number.
• %f Floating point number.
• %o Object hyperlink.

e.g.

console.log("generation 0:\t%f, %f, %f", a1a1, a1a2, a2a2);

BTW, to see the output:

• In Chrome, use shortcut Ctrl + Shift + J or F12 to open developer tool.
• In Firefox, use shortcut Ctrl + Shift + K or F12 to open developer tool.

@Update - nodejs support

Seems nodejs don't support %f, instead, could use %d in nodejs. With %d number will be printed as floating number, not just integer.

As Chris said before me, just an a should override. For example:

a { color:red; }
a:hover { color:blue; }
.nav a { color:green; }

In this instance the .nav a would ALWAYS be green, the :hover wouldn't apply to it.

If there's some other rule affecting it, you COULD use !important, but you shouldn't. It's a bad habit to fall into.

.nav a { color:green !important; } /*I'm a bad person and shouldn't use !important */

Then it'll always be green, irrelevant of any other rule.

I guess you have some conflict with other package. For me it was six. So you need to use a command like this:

pip install google-api-python-client --upgrade --ignore-installed six

or

pip install --ignore-installed six

This works just fine,

$model=Model::all()->random(1)->first();

you can also change argument in random function to get more than one record.

Note: not recommended if you have huge data as this will fetch all rows first and then returns random value.

Install both of them using homebrew separately.

brew install boost
brew install bjam

In SQL Server 2016 SSMS expand 'DATABASNAME' > expand 'SECURITY' > expand 'SCHEMA' ; right click 'SCHEMAS' from the popup left click 'NEW SCHEMAS...' add the name on the window that opens and add an owner i.e dbo click 'OK' button

Old post, but I just ran into a very similar problem. After some experimenting, I found that you can do this with a single command:

kill $(ps aux | grep <process_name> | grep -v "grep" | cut -d " " -f2)

In OP's case, <process_name> would be "gedit file.txt".

Not sure if this helps, but with XSL, I'd do something like:

<xsl:for-each select="a/b">
    <xsl:value-of select="c"/>
    <xsl:value-of select="d"/>
    <xsl:value-of select="e"/>
</xsl:for-each>

and won't this XPath select all children of B nodes:

a/b/*

You can set values from html like this. I don't think there is a direct solution from angular yet.

 <div style="visibility: hidden;">{{activeTitle='home'}}</div>

You can use margin auto. With flex, the div seems to be centered vertically too.

body,
html {
  height: 100%;
  margin: 0;
}
.site {
  height: 100%;
  display: flex;
}
.site .box {
  background: #0ff;
  max-width: 20vw;
  margin: auto;
}

<div class="site">
  <div class="box">
    <h1>blabla</h1>
    <p>blabla</p>
    <p>blablabla</p>
    <p>lbibdfvkdlvfdks</p>
  </div>
</div>

For IE9+:

function ready(fn) {
  if (document.readyState != 'loading'){
    fn();
  } else {
    document.addEventListener('DOMContentLoaded', fn);
  }
}

Use the following code:

System.out.println("\f");

'\f' is an escape sequence which represents FormFeed. This is what I have used in my projects to clear the console. This is simpler than the other codes, I guess.

If you have all your JavaScript files in multiple folders under one folder that works out very well, and that's what I did:

I am assuming that you have enough permissions to create this directory.

To fix your problem, you can either ssh to some other location:

ssh [email protected]

and accept new key - it will create directory ~/.ssh and known_hosts underneath, or simply create it manually using

mkdir ~/.ssh
chmod 700 ~/.ssh

Note that chmod 700 is an important step!

After that, ssh-keygen should work without complaints.

AFAIK, both substring() and indexOf() are supported by both Mozilla and IE. However, note that substr() might not be supported on earlier versions of some browsers (esp. Netscape/Opera).

Your post indicates that you already know how to do it using substring() and indexOf(), so I'm not posting a code sample.

GraphQL query format was designed in order to allow:

1. Both query and result shape be exactly the same.
2. The server knows exactly the requested fields, thus the client downloads only essential data.

However, according to GraphQL documentation, you may create fragments in order to make selection sets more reusable:

# Only most used selection properties

fragment UserDetails on User {
    id,
    username
} 

Then you could query all user details by:

FetchUsers {
    users() {
        ...UserDetails
    }
}

You can also add additional fields alongside your fragment:

FetchUserById($id: ID!) {
    users(id: $id) {
        ...UserDetails
        count
    }
}

Try setting the JAVA_LIB variable also.

Another approach is to use Collectors.groupingBy of indices and then map the grouped indices to the actual elements:

    final List<Integer> numbers = range(1, 12)
            .boxed()
            .collect(toList());
    System.out.println(numbers);

    final List<List<Integer>> groups = range(0, numbers.size())
            .boxed()
            .collect(groupingBy(index -> index / 4))
            .values()
            .stream()
            .map(indices -> indices
                    .stream()
                    .map(numbers::get)
                    .collect(toList()))
            .collect(toList());
    System.out.println(groups);

Output:

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]

[[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11]]

You create an interface first, then define a method, which would act as a callback. In this example we would have two classes, one classA and another classB

Interface:

public interface OnCustomEventListener{
  public void onEvent();   //method, which can have parameters
}

the listener itself in classB (we only set the listener in classB)

private OnCustomEventListener mListener; //listener field

//setting the listener
public void setCustomEventListener(OnCustomEventListener eventListener) {
   this.mListener=eventListener;
}

in classA, how we start listening for whatever classB has to tell

classB.setCustomEventListener(new OnCustomEventListener(){
    public void onEvent(){
       //do whatever you want to do when the event is performed.
    }
});  

how do we trigger an event from classB (for example on button pressed)

if(this.mListener!=null){
   this.mListener.onEvent();
}

P.S. Your custom listener may have as many parameters as you want

Another very basic free profiler: http://expressprofiler.codeplex.com

This is a mix of HTML and code but it's pretty basic, easy to understand and should be fairly simple to decouple to suit your needs I think.

If using IIS 7 or IIS 7.5 you can use

<system.webServer>
    <defaultDocument>
        <files>
            <clear />
            <add value="CreateThing.aspx" />
        </files>
    </defaultDocument>
</system.webServer>

https://docs.microsoft.com/en-us/iis/configuration/system.webServer/defaultDocument/

I found the answer is very very simple...

// It is in java, but it should be same in pyspark
Column col = ds.col("colName"); //the column object
String theNameOftheCol = col.toString();

The variable "theNameOftheCol" is "colName"

Another thing to check before you start playing with Xcode preferences is:

Select your target and go to Build Settings > Packaging > Wrapper Extension

The value there should be: app

If not double click it and type "app" without the qoutes.

.carousel-inner > .item > img {
    margin: 0 auto;
}

This simple solution worked for me

You can make use of VALUES - available in Postgres:

INSERT INTO person (name)
    SELECT name FROM person
    UNION 
    VALUES ('Bob')
    EXCEPT
    SELECT name FROM person;

This worked for me:

import re
thestring = "text1\ntext2\nhttp://url.com/bla1/blah1/\ntext3\ntext4\nhttp://url.com/bla2/blah2/\ntext5\ntext6"

URLless_string = re.sub(r'\w+:\/{2}[\d\w-]+(\.[\d\w-]+)*(?:(?:\/[^\s/]*))*', '', thestring)
print URLless_string

Result:

text1
text2

text3
text4

text5
text6

EDIT Until such time as StackOverflow allows us to version our answers, this is an answer that works for Android 3 and below. Please don't downvote it because it's not working for you now, because it definitely works with older Android versions.

You should only need to add one line to your onCreateDialog() method:

@Override
protected Dialog onCreateDialog(int id) {
    //all other dialog stuff (which dialog to display)

    //this line is what you need:
    dialog.getWindow().setFlags(LayoutParams.FLAG_FULLSCREEN, LayoutParams.FLAG_FULLSCREEN);

    return dialog;
}

Here's how you can modify a running container to update its environment variables. This assumes you're running on Linux. I tested it with Docker 19.03.8

Live Restore

First, ensure that your Docker daemon is set to leave containers running when it's shut down. Edit your /etc/docker/daemon.json, and add "live-restore": true as a top-level key.

sudo vim /etc/docker/daemon.json

My file looks like this:

{

Get the Container ID

Save the ID of the container you want to edit for easier access to the files.

export CONTAINER_ID=`docker inspect --format="{{.Id}}" <YOUR CONTAINER NAME>`

Edit Container Configuration

Edit the configuration file, go to the "Env" section, and add your key.

sudo vim /var/lib/docker/containers/$CONTAINER_ID/config.v2.json

My file looks like this:

...,"Env":["TEST=1",...

Stop and Start Docker

I found that restarting Docker didn't work, I had to stop and then start Docker with two separate commands.

sudo systemctl stop docker
sudo systemctl start docker

Because of live-restore, your containers should stay up.

Verify That It Worked

docker exec <YOUR CONTAINER NAME> bash -c 'echo $TEST'

Single quotes are important here.

You can also verify that the uptime of your container hasn't changed:

docker ps

Use the System.Environment class.

The methods

var value = System.Environment.GetEnvironmentVariable(variable [, Target])

and

System.Environment.SetEnvironmentVariable(variable, value [, Target])

will do the job for you.

The optional parameter Target is an enum of type EnvironmentVariableTarget and it can be one of: Machine, Process, or User. If you omit it, the default target is the current process.

lace to store your loaded class definition and metadata. If a large code-base project is loaded, the insufficient Perm Gen size will cause the popular Java.Lang.OutOfMemoryError: PermGen.

There's no need for LINQ here, just call Sort:

list.Sort();

Example code:

List<int> list = new List<int> { 5, 7, 3 };
list.Sort();
foreach (int x in list)
{
    Console.WriteLine(x);
}

Result:

3
5
7

In my case (not necessarily be the solution for you, but it may be helpful for someone), the solution was:

1. Go menu Tools ? Extensions and Updates

2. Select the Online tab from the right panel

3. Search for the words web tools, and then select Microsoft ASP.NET and Web Tools and install it.

In my case, this was missing from my computer because of a lot of repairing operations for Visual Studio.

you can do like this also

        long[,] arr = new long[4, 4] { { 0, 0, 0, 0 }, { 1, 1, 1, 1 }, { 0, 0, 0, 0 }, { 1, 1, 1, 1 }};

        for (int i = 0; i < arr.GetLength(0); i++)
        {
            for (int j = 0; j < arr.GetLength(1); j++)
            {
                Console.Write(arr[i,j]+" ");
            }
            Console.WriteLine();
        }

Based on your comment, moddify this:

$( '.bgHeaderH2' ).html (); // will return whatever is inside the DIV

to:

$( '.bgHeaderH2', $( this ) ).html (); // will return whatever is inside the DIV

The main difference is that Boolean is an object and boolean is an primitive.

• Object default value is null;
• boolean default value is false;

This can be installed via conda with the command conda install -c anaconda python=3.7 as per https://anaconda.org/anaconda/python.

Though not all packages support 3.7 yet, running conda update --all may resolve some dependency failures.

for a relative answer, use .

test with:

$ myDir=.
$ ls $myDir
$ cd /
$ ls $myDir

The first ls will show you everything in the current directory, the second will show you everything in the root directory (/).

TL;DR

TEXT

• fixed max size of 65535 characters (you cannot limit the max size)
• takes 2 + c bytes of disk space, where c is the length of the stored string.
• cannot be (fully) part of an index. One would need to specify a prefix length.

VARCHAR(M)

• variable max size of M characters
• M needs to be between 1 and 65535
• takes 1 + c bytes (for M ≤ 255) or 2 + c (for 256 ≤ M ≤ 65535) bytes of disk space where c is the length of the stored string
• can be part of an index

More Details

TEXT has a fixed max size of 2¹6-1 = 65535 characters.
VARCHAR has a variable max size M up to M = 2¹6-1.
So you cannot choose the size of TEXT but you can for a VARCHAR.

The other difference is, that you cannot put an index (except for a fulltext index) on a TEXT column.
So if you want to have an index on the column, you have to use VARCHAR. But notice that the length of an index is also limited, so if your VARCHAR column is too long you have to use only the first few characters of the VARCHAR column in your index (See the documentation for CREATE INDEX).

But you also want to use VARCHAR, if you know that the maximum length of the possible input string is only M, e.g. a phone number or a name or something like this. Then you can use VARCHAR(30) instead of TINYTEXT or TEXT and if someone tries to save the text of all three "Lord of the Ring" books in your phone number column you only store the first 30 characters :)

Edit: If the text you want to store in the database is longer than 65535 characters, you have to choose MEDIUMTEXT or LONGTEXT, but be careful: MEDIUMTEXT stores strings up to 16 MB, LONGTEXT up to 4 GB. If you use LONGTEXT and get the data via PHP (at least if you use mysqli without store_result), you maybe get a memory allocation error, because PHP tries to allocate 4 GB of memory to be sure the whole string can be buffered. This maybe also happens in other languages than PHP.

However, you should always check the input (Is it too long? Does it contain strange code?) before storing it in the database.

Notice: For both types, the required disk space depends only on the length of the stored string and not on the maximum length.
E.g. if you use the charset latin1 and store the text "Test" in VARCHAR(30), VARCHAR(100) and TINYTEXT, it always requires 5 bytes (1 byte to store the length of the string and 1 byte for each character). If you store the same text in a VARCHAR(2000) or a TEXT column, it would also require the same space, but, in this case, it would be 6 bytes (2 bytes to store the string length and 1 byte for each character).

For more information have a look at the documentation.

Finally, I want to add a notice, that both, TEXT and VARCHAR are variable length data types, and so they most likely minimize the space you need to store the data. But this comes with a trade-off for performance. If you need better performance, you have to use a fixed length type like CHAR. You can read more about this here.
