> grepl("^[^_]+_1",s)
[1] FALSE
> grepl("^[^_]+_2",s)
[1] TRUE

basically, look for everything at the beginning except _, and then the _2.

+1 to @Ananda_Mahto for suggesting grepl instead of grep.

I need to select every production with a category that doesn't contain "Business"

Although I upvoted @Arran's answer as correct, I would also add this... Strictly interpreted, the OP's specification would be implemented as

//production[category[not(contains(., 'Business'))]]

rather than

//production[not(contains(category, 'Business'))]

The latter selects every production whose first category child doesn't contain "Business". The two XPath expressions will behave differently when a production has no category children, or more than one.

It doesn't make any difference in practice as long as every <production> has exactly one <category> child, as in your short example XML. Whether you can always count on that being true or not, depends on various factors, such as whether you have a schema that enforces that constraint. Personally, I would go for the more robust option, since it doesn't "cost" much... assuming your requirement as stated in the question is really correct (as opposed to e.g. 'select every production that doesn't have a category that contains "Business"').

You can put the values as the table's keys. For example:

function addToSet(set, key)
    set[key] = true
end

function removeFromSet(set, key)
    set[key] = nil
end

function setContains(set, key)
    return set[key] ~= nil
end

There's a more fully-featured example here.

Declare additional helper function like this:

template <class T, class I >
bool vectorContains(const vector<T>& v, I& t)
{
    bool found = (std::find(v.begin(), v.end(), t) != v.end());
    return found;
}

And use it like this:

void Project::AddPlatform(const char* platform)
{
    if (!vectorContains(platforms, platform))
        platforms.push_back(platform);
}

Snapshot of example can be found here:

https://github.com/tapika/cppscriptcore/blob/b7f3d62747494a52a440482e841ffb016a3fc56e/SolutionProjectModel/Project.cpp#L13

If you are happy with "blah" in somestring but want it to be a function/method call, you can probably do this

import operator

if not operator.contains(somestring, "blah"):
    continue

All operators in Python can be more or less found in the operator module including in.

If you have a list of words you can do a method like this:

public bool ContainWords(List<string> wordList, string text)
{
   foreach(string currentWord in wordList)
      if(!text.Contains(currentWord))
         return false;
   return true;
}

Better to use a HashSet than an ArrayList when you are checking for existence of a value. Java docs for HashSet says: "This class offers constant time performance for the basic operations (add, remove, contains and size)"

ArrayList.contains() might have to iterate the whole list to find the instance you are looking for.

I've approached this in a different way. I've created a function which simply returns true or false.. Usage:

If FieldContains("A;B;C",MyFieldVariable,True|False) then

.. Do Something

End If

Public Function FieldContains(Searchfor As String, SearchField As String, AllowNulls As Boolean) As Boolean

       If AllowNulls And Len(SearchField) = 0 Then Return True

        For Each strSearchFor As String In Searchfor.Split(";")
            If UCase(SearchField) = UCase(strSearchFor) Then
                Return True
            End If
        Next

        Return False

    End Function

    IF CHARINDEX('TextToSearch',@TextWhereISearch, 0) > 0 => TEXT EXISTS

    IF PATINDEX('TextToSearch', @TextWhereISearch) > 0 => TEXT EXISTS

    Additionally we can also use LIKE but I usually don't use LIKE.

One line solution

substringsArray.some(substring=>yourBigString.includes(substring))

Returns true\false if substring exists\does'nt exist

Needs ES6 support

Maybe

if (inventory.contains("bread") && !inventory.contains("water"))

Or

if (inventory.contains("bread")) {
    if (!inventory.contains("water")) {
        // do something here
    } 
}

switch(message)
{
  case "test":
    Console.WriteLine("yes");
    break;                
  default:
    if (Contains("test2")) {
      Console.WriteLine("yes for test2");
    }
    break;
}

If you're using Selenium with Firefox you should be able to use EXSLT extensions, and regexp:test()

Does this work for you?

String expr = "//*[regexp:test(@id, 'sometext[0-9]+_text')]";
driver.findElement(By.xpath(expr));

You could use regular expressions as it's better for word matching compared to strpos, as mentioned by other users. A strpos check for are will also return true for strings such as: fare, care, stare, etc. These unintended matches can simply be avoided in regular expression by using word boundaries.

A simple match for are could look something like this:

$a = 'How are you?';

if (preg_match('/\bare\b/', $a)) {
    echo 'true';
}

On the performance side, strpos is about three times faster. When I did one million compares at once, it took preg_match 1.5 seconds to finish and for strpos it took 0.5 seconds.

Edit: In order to search any part of the string, not just word by word, I would recommend using a regular expression like

$a = 'How are you?';
$search = 'are y';
if(preg_match("/{$search}/i", $a)) {
    echo 'true';
}

The i at the end of regular expression changes regular expression to be case-insensitive, if you do not want that, you can leave it out.

Now, this can be quite problematic in some cases as the $search string isn't sanitized in any way, I mean, it might not pass the check in some cases as if $search is a user input they can add some string that might behave like some different regular expression...

Also, here's a great tool for testing and seeing explanations of various regular expressions Regex101

To combine both sets of functionality into a single multi-purpose function (including with selectable case sensitivity), you could use something like this:

function FindString($needle,$haystack,$i,$word)
{   // $i should be "" or "i" for case insensitive
    if (strtoupper($word)=="W")
    {   // if $word is "W" then word search instead of string in string search.
        if (preg_match("/\b{$needle}\b/{$i}", $haystack)) 
        {
            return true;
        }
    }
    else
    {
        if(preg_match("/{$needle}/{$i}", $haystack)) 
        {
            return true;
        }
    }
    return false;
    // Put quotes around true and false above to return them as strings instead of as bools/ints.
}

One more thing to take in mind, is that \b will not work in different languages other than english.

The explanation for this and the solution is taken from here:

\b represents the beginning or end of a word (Word Boundary). This regex would match apple in an apple pie, but wouldn’t match apple in pineapple, applecarts or bakeapples.

How about “café”? How can we extract the word “café” in regex? Actually, \bcafé\b wouldn’t work. Why? Because “café” contains non-ASCII character: é. \b can’t be simply used with Unicode such as ??????, ??, ????? and .

When you want to extract Unicode characters, you should directly define characters which represent word boundaries.

The answer: (?<=[\s,.:;"']|^)UNICODE_WORD(?=[\s,.:;"']|$)

So in order to use the answer in PHP, you can use this function:

function contains($str, array $arr) {
    // Works in Hebrew and any other unicode characters
    // Thanks https://medium.com/@shiba1014/regex-word-boundaries-with-unicode-207794f6e7ed
    // Thanks https://www.phpliveregex.com/
    if (preg_match('/(?<=[\s,.:;"\']|^)' . $word . '(?=[\s,.:;"\']|$)/', $str)) return true;
}

And if you want to search for array of words, you can use this:

function arrayContainsWord($str, array $arr)
{
    foreach ($arr as $word) {
        // Works in Hebrew and any other unicode characters
        // Thanks https://medium.com/@shiba1014/regex-word-boundaries-with-unicode-207794f6e7ed
        // Thanks https://www.phpliveregex.com/
        if (preg_match('/(?<=[\s,.:;"\']|^)' . $word . '(?=[\s,.:;"\']|$)/', $str)) return true;
    }
    return false;
}

As of PHP 8.0.0 you can now use str_contains

<?php
    if (str_contains('abc', '')) {
        echo "Checking the existence of the empty string will always 
        return true";
    }

You can also use the same syntax for an array. For example, searching within a Pandas series:

ser = pd.Series(['some', 'strings', 'to', 'query'])

if item in ser.values:
    # do stuff

SEARCH does not return 0 if there is no match, it returns #VALUE!. So you have to wrap calls to SEARCH with IFERROR.

For example...

=IF(IFERROR(SEARCH("cat", A1), 0), "cat", "none")

or

=IF(IFERROR(SEARCH("cat",A1),0),"cat",IF(IFERROR(SEARCH("22",A1),0),"22","none"))

Here, IFERROR returns the value from SEARCH when it works; the given value of 0 otherwise.

You can use java.util.regex.Pattern with the CASE_INSENSITIVE flag for case insensitive matching:

Pattern.compile(Pattern.quote(strptrn), Pattern.CASE_INSENSITIVE).matcher(str1).find();

So am I assuming correctly that uid is a Unique Identifier (Guid)? Is this just an example of a possible scenario or are you really trying to find a guid that matches an array of strings?

If this is true you may want to really rethink this whole approach, this seems like a really bad idea. You should probably be trying to match a Guid to a Guid

Guid id = new Guid(uid);
var query = from xx in table
            where xx.uid == id
            select xx;

I honestly can't imagine a scenario where matching a string array using "contains" to the contents of a Guid would be a good idea. For one thing, Contains() will not guarantee the order of numbers in the Guid so you could potentially match multiple items. Not to mention comparing guids this way would be way slower than just doing it directly.

I know that best way is str.indexOf(s) !== -1; http://hayageek.com/javascript-string-contains/

I suggest another way(str.replace(s1, "") !== str):

var str = "Hello World!", s1 = "ello", s2 = "elloo";_x000D_
alert(str.replace(s1, "") !== str);_x000D_
alert(str.replace(s2, "") !== str);

If you want a list of strings containing your string:

var newList = myList.Where(x => x.Contains(myString)).ToList();

Another option is to use Linq FirstOrDefault

var element = myList.Where(x => x.Contains(myString)).FirstOrDefault();

Keep in mind that Contains method is case sensitive.

In addition to what other have said, you may also be interested to know that what in does is to call the list.__contains__ method, that you can define on any class you write and can get extremely handy to use python at his full extent.  

A dumb use may be:

>>> class ContainsEverything:
    def __init__(self):
        return None
    def __contains__(self, *elem, **k):
        return True


>>> a = ContainsEverything()
>>> 3 in a
True
>>> a in a
True
>>> False in a
True
>>> False not in a
False
>>>         

If you are worrying about Case sensitive change the case and compare the string.

 if (stringvalue.toLocaleLowerCase().indexOf("mytexttocompare")!=-1)
        {

            alert("found");
        }

If you need to perform this List.contains(Object with field value equal to x) repeatedly, a simple and efficient workaround would be:

List<field obj type> fieldOfInterestValues = new ArrayList<field obj type>;
for(Object obj : List) {
    fieldOfInterestValues.add(obj.getFieldOfInterest());
}

Then the List.contains(Object with field value equal to x) would be have the same result as fieldOfInterestValues.contains(x);

=IF(COUNTIF(A1:D1,FALSE)>0,FALSE,TRUE)

(or you can specify any other range to look in)

You can use the invert (~) operator (which acts like a not for boolean data):

new_df = df[~df["col"].str.contains(word)]

, where new_df is the copy returned by RHS.

contains also accepts a regular expression...

If the above throws a ValueError, the reason is likely because you have mixed datatypes, so use na=False:

new_df = df[~df["col"].str.contains(word, na=False)]

Or,

new_df = df[df["col"].str.contains(word) == False]

var d = $('.text_div');
d.text(d.text().trim().replace(/contains/i, "hello everyone"));

Dave answer is good. But I suggest this implementation which is more efficient and doesn't use nested loops.

def contains(small_list, big_list):
    """
    Returns index of start of small_list in big_list if big_list
    contains small_list, otherwise -1.
    """
    loop = True
    i, curr_id_small= 0, 0
    while loop and i<len(big_list):
        if big_list[i]==small_list[curr_id_small]:
            if curr_id_small==len(small_list)-1:
                loop = False
            else:
                curr_id_small += 1
        else:
            curr_id_small = 0
        i=i+1
    if not loop:
        return i-len(small_list)
    else:
        return -1

You can use IndexOf() like this:

string title = "STRING";

if (title.IndexOf("string", 0, StringComparison.CurrentCultureIgnoreCase) != -1)
{
    // The string exists in the original
}

Since 0 (zero) can be an index, you check against -1.

MSDN

The zero-based index position of value if that string is found, or -1 if it is not. If value is String.Empty, the return value is 0.

Just to clarify, the reason why there is no member like contains() in these container types is because it would open you up to writing inefficient code. Such a method would probably just do a this->find(key) != this->end() internally, but consider what you do when the key is indeed present; in most cases you'll then want to get the element and do something with it. This means you'd have to do a second find(), which is inefficient. It's better to use find directly, so you can cache your result, like so:

auto it = myContainer.find(key);
if (it != myContainer.end())
{
    // Do something with it, no more lookup needed.
}
else
{
    // Key was not present.
}

Of course, if you don't care about efficiency, you can always roll your own, but in that case you probably shouldn't be using C++... ;)

If you have a list and you want to know where within the list an element exists that matches a given criteria, you can use the FindIndex instance method. Such as

int index = list.FindIndex(f => f.Bar == 17);

Where f => f.Bar == 17 is a predicate with the matching criteria.

In your case you might write

int index = pricePublicList.FindIndex(item => item.Size == 200);
if (index >= 0) 
{
    // element exists, do what you need
}

I prefer simplicity:

var days = [1, 2, 3, 4, 5];
if ( 2 in days ) {console.log('weekday');}

You need to implement IEquatable or override Equals() and GetHashCode()

For example:

public class CartProduct : IEquatable<CartProduct>
{
    public Int32 ID;
    public String Name;
    public Int32 Number;
    public Decimal CurrentPrice;

    public CartProduct(Int32 ID, String Name, Int32 Number, Decimal CurrentPrice)
    {
        this.ID = ID;
        this.Name = Name;
        this.Number = Number;
        this.CurrentPrice = CurrentPrice;
    }

    public String ToString()
    {
        return Name;
    }

    public bool Equals( CartProduct other )
    {
        // Would still want to check for null etc. first.
        return this.ID == other.ID && 
               this.Name == other.Name && 
               this.Number == other.Number && 
               this.CurrentPrice == other.CurrentPrice;
    }
}

You could simply use ArrayUtils.contains from Apache Commons Lang library.

public boolean contains(final int[] array, final int key) {     
    return ArrayUtils.contains(array, key);
}

The second (assuming you means CONTAINS, and actually put it in a valid query) should be faster, because it can use some form of index (in this case, a full text index). Of course, this form of query is only available if the column is in a full text index. If it isn't, then only the first form is available.

The first query, using LIKE, will be unable to use an index, since it starts with a wildcard, so will always require a full table scan.

The CONTAINS query should be:

SELECT * FROM table WHERE CONTAINS(Column, 'test');

function ConfirmDelete()
{
  var x = confirm("Are you sure you want to delete?");
  if (x)
      return true;
  else
    return false;
}


<input type="button" onclick="ConfirmDelete()">

Incase 'Instant Run' is enable, then just disable it.

To solve this problem.

1. Step1: cd projectName
2. Step2: npm update
3. Step3: ng serve -o

For example :

You can use the parseInt() function to convert the string to a number, e.g:

parseInt($('#elem').css('top'));

Update: (as suggested by Ben): You should give the radix too:

parseInt($('#elem').css('top'), 10);

Forces it to be parsed as a decimal number, otherwise strings beginning with '0' might be parsed as an octal number (might depend on the browser used).

Your config file does not include any references to "origin" remote. That section looks like this:

[remote "origin"]
    url = [email protected]:repository.git
    fetch = +refs/heads/*:refs/remotes/origin/*

You need to add the remote using git remote add before you can use it.

Alternative would be to use Apache CommonsIO FileUtils.getUserDirectory() instead of System.getProperty("user.home"). It will get you the same result and there is no chance to introduce a typo when specifying system property.

There is a big chance you already have Apache CommonsIO library in your project. Don't introduce it if you plan to use it only for getting user home directory.

I use a package.json for my packages and a config.js for my configuration, which looks like:

var config = {};

config.twitter = {};
config.redis = {};
config.web = {};

config.default_stuff =  ['red','green','blue','apple','yellow','orange','politics'];
config.twitter.user_name = process.env.TWITTER_USER || 'username';
config.twitter.password=  process.env.TWITTER_PASSWORD || 'password';
config.redis.uri = process.env.DUOSTACK_DB_REDIS;
config.redis.host = 'hostname';
config.redis.port = 6379;
config.web.port = process.env.WEB_PORT || 9980;

module.exports = config;

I load the config from my project:

var config = require('./config');

and then I can access my things from config.db_host, config.db_port, etc... This lets me either use hardcoded parameters, or parameters stored in environmental variables if I don't want to store passwords in source control.

I also generate a package.json and insert a dependencies section:

"dependencies": {
  "cradle": "0.5.5",
  "jade": "0.10.4",
  "redis": "0.5.11",
  "socket.io": "0.6.16",
  "twitter-node": "0.0.2",
  "express": "2.2.0"
}

When I clone the project to my local machine, I run npm install to install the packages. More info on that here.

The project is stored in GitHub, with remotes added for my production server.

To select all anchors with the data attribute data-customerID==22, you should include the a to limit the scope of the search to only that element type. Doing data attribute searches in a large loop or at high frequency when there are many elements on the page can cause performance issues.

$('a[data-customerID="22"]');

In two way ssl the client asks for servers digital certificate and server ask for the same from the client. It is more secured as it is both ways, although its bit slow. Generally we dont follow it as the server doesnt care about the identity of the client, but a client needs to make sure about the integrity of server it is connecting to.

Yes, that's possible, albeit not literally the <td>, but what's in it. The simple trick is, to make sure that the content extends to the borders of the cell (it won't include the borders itself though).

As already explained, this isn't semantically correct. An a element is an inline element and should not be used as block-level element. However, here's an example (but JavaScript plus a td:hover CSS style will be much neater) that works in most browsers:

<td>
  <a href="http://example.com">
    <div style="height:100%;width:100%">
      hello world
    </div>
  </a>
</td>

PS: it's actually neater to change a in a block-level element using CSS as explained in another solution in this thread. it won't work well in IE6 though, but that's no news ;)

Alternative (non-advised) solution

If your world is only Internet Explorer (rare, nowadays), you can violate the HTML standard and write this, it will work as expected, but will be highly frowned upon and be considered ill-advised (you haven't heard this from me). Any other browser than IE will not render the link, but will show the table correctly.

<table>
    <tr>
        <a href="http://example.com"><td  width="200">hello world</td></a>
    </tr>
</table>

Note that the .value attribute is a JavaScript feature. If you want to use jQuery, use:

$('#pid').val()

to get the value, and:

$('#pid').val('value')

to set it.

http://api.jquery.com/val/

Regarding your second issue, I have never tried automatically setting the HTML value using the load method. For sure, you can do something like this:

$('#subtotal').load( 'compz.php?prodid=' + x + '&qbuys=' + y, function(response){ $('#subtotal').val(response);
});

Note that the code above is untested.

http://api.jquery.com/load/

Here is what I learned: PYTHONPATH is a directory to add to the Python import search path "sys.path", which is made up of current dir. CWD, PYTHONPATH, standard and shared library, and customer library. For example:

% python3 -c "import sys;print(sys.path)"
['', 
'/home/username/Documents/DjangoTutorial/mySite', 
'/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', 
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']

where the first path '' denotes the current dir., the 2nd path is via

%export PYTHONPATH=/home/username/Documents/DjangoTutorial/mySite 

which can be added to ~/.bashrc to make it permanent, and the rest are Python standard and dynamic shared library plus third-party library such as django.

As said not to mess with PYTHONHOME, even setting it to '' or 'None' will cause python3 shell to stop working:

% export PYTHONHOME=''
% python3
Fatal Python error: Py_Initialize: Unable to get the locale encoding
ModuleNotFoundError: No module named 'encodings'

Current thread 0x00007f18a44ff740 (most recent call first):
Aborted (core dumped)

Note that if you start a Python script, the CWD will be the script's directory. For example:

username@bud:~/Documents/DjangoTutorial% python3 mySite/manage.py runserver
==== Printing sys.path ====
/home/username/Documents/DjangoTutorial/mySite # CWD is where manage.py resides
/usr/lib/python3.6
/usr/lib/python3.6/lib-dynload
/usr/local/lib/python3.6/dist-packages
/usr/lib/python3/dist-packages

You can also append a path to sys.path at run-time: Suppose you have a file Fibonacci.py in ~/Documents/Python directory:

username@bud:~/Documents/DjangoTutorial% python3 
>>> sys.path.append("/home/username/Documents")
>>> print(sys.path)
['', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', 
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages', 
'/home/username/Documents']
>>> from Python import Fibonacci as fibo

or via

% PYTHONPATH=/home/username/Documents:$PYTHONPATH
% python3
>>> print(sys.path)
['', 
'/home/username/Documents', '/home/username/Documents/DjangoTutorial/mySite', 
'/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', 
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']
>>> from Python import Fibonacci as fibo

I add common parts as header and footer using Server Side Includes. No HTML and no JavaScript is needed. Instead, the webserver automatically adds the included code before doing anything else.

Just add the following line where you want to include your file:

<!--#include file="include_head.html" -->

As I have set ItemAnimators. The ItemDecorator don't enter or exit along with the animation.

I simply ended up in having a view line in my item view layout file of each item. It solved my case. DividerItemDecoration felt to be too much of sorcery for a simple divider.

<View
    android:layout_width="match_parent"
    android:layout_height="1px"
    android:layout_marginLeft="5dp"
    android:layout_marginRight="5dp"
    android:background="@color/lt_gray"/>

Template Syntax Error: is due to many reasons one of them is {{ post.date_posted|date: "F d, Y" }} is the space between colon(:) and quote (") if u remove the space then it work like this ..... {{ post.date_posted|date:"F d, Y" }}

Great explanation here:
https://www.cuelogic.com/blog/using-framelayout-for-designing-xml-layouts-in-android

LinearLayout arranges elements side by side either horizontally or vertically.

RelativeLayout helps you arrange your UI elements based on specific rules. You can specify rules like: align this to parent’s left edge, place this to the left/right of this elements etc.

AbsoluteLayout is for absolute positioning i.e. you can specify exact co-ordinates where the view should go.

FrameLayout allows placements of views along Z-axis. That means that you can stack your view elements one above the other.

If your system has systemctl

sudo systemctl reload nginx

If your system supports service (using debian/ubuntu) try this

sudo service nginx reload

If not (using centos/fedora/etc) you can try the init script

sudo /etc/init.d/nginx reload

When you want to trigger javascript code from an anchor tag, the onclick handler should be used rather than the javascript: pseudo-protocol. The javascript code that runs within the onclick handler must return true or false (or an expression than evalues to true or false) back to the tag itself - if it returns true, then the HREF of the anchor will be followed like a normal link. If it returns false, then the HREF will be ignored. This is why "return false;" is often included at the end of the code within an onclick handler.

Machine learning packages like tensorflow 2.x are designed to work only on 64 bit Python as they are memory intensive.

A cookie is a object with key value pair to store information related to the customer. Main objective is to personalize the customer's experience.

An utility method can be created like

private Cookie createCookie(String cookieName, String cookieValue) {
    Cookie cookie = new Cookie(cookieName, cookieValue);
    cookie.setPath("/");
    cookie.setMaxAge(MAX_AGE_SECONDS);
    cookie.setHttpOnly(true);
    cookie.setSecure(true);
    return cookie;
}

If storing important information then we should alsways put setHttpOnly so that the cookie cannot be accessed/modified via javascript. setSecure is applicable if you are want cookies to be accessed only over https protocol.

using above utility method you can add cookies to response as

Cookie cookie = createCookie("name","value");
response.addCookie(cookie);

try this code. then 'formId' div can set the image.

$('#formId').append('<iframe style="width: 100%;height: 500px" src="/document_path/name.jpg"' +
 'title="description"> </iframe> ');

Well, the reason to use the pointer would be exactly the same that the reason to use pointers in C allocated with malloc: if you want your object to live longer than your variable!

It is even highly recommended to NOT use the new operator if you can avoid it. Especially if you use exceptions. In general it is much safer to let the compiler free your objects.

@ and @@ in modules also work differently when a class extends or includes that module.

So given

module A
    @a = 'module'
    @@a = 'module'

    def get1
        @a          
    end     

    def get2
        @@a         
    end     

    def set1(a) 
        @a = a      
    end     

    def set2(a) 
        @@a = a     
    end     

    def self.set1(a)
        @a = a      
    end     

    def self.set2(a)
        @@a = a     
    end     
end 

Then you get the outputs below shown as comments

class X
    extend A

    puts get1.inspect # nil
    puts get2.inspect # "module"

    @a = 'class' 
    @@a = 'class' 

    puts get1.inspect # "class"
    puts get2.inspect # "module"

    set1('set')
    set2('set')

    puts get1.inspect # "set" 
    puts get2.inspect # "set" 

    A.set1('sset')
    A.set2('sset')

    puts get1.inspect # "set" 
    puts get2.inspect # "sset"
end 

class Y
    include A

    def doit
        puts get1.inspect # nil
        puts get2.inspect # "module"

        @a = 'class'
        @@a = 'class'

        puts get1.inspect # "class"
        puts get2.inspect # "class"

        set1('set')
        set2('set')

        puts get1.inspect # "set"
        puts get2.inspect # "set"

        A.set1('sset')
        A.set2('sset')

        puts get1.inspect # "set"
        puts get2.inspect # "sset"
    end
end

Y.new.doit

So use @@ in modules for variables you want common to all their uses, and use @ in modules for variables you want separate for every use context.

Please use the following query and alter your table : CREATE SEQUENCE user_id_seq START 1; ALTER TABLE product.users ALTER COLUMN user_id SET DEFAULT nextval('user_id_seq'); ALTER SEQUENCE users.user_id_seq OWNED BY users.user_id;

and use the this in your entity class

@GeneratedValue(strategy = GenerationType.SEQUENCE,generator="user_id_seq")

It means not to output the respective command. Compare the following two batch files:

@echo foo

and

echo foo

The former has only foo as output while the latter prints

H:\Stuff>echo foo 
foo

(here, at least). As can be seen the command that is run is visible, too.

echo off will turn this off for the complete batch file. However, the echo off call itself would still be visible. Which is why you see @echo off in the beginning of batch files. Turn off command echoing and don't echo the command turning it off.

Removing that line (or commenting it out) is often a helpful debugging tool in more complex batch files as you can see what is run prior to an error message.

<script type="text/javascript">
jQuery(function () {
    var container = jQuery("\#content");
    jQuery(container)
     .kendoGrid({
         selectable: "single row",
         dataSource: new kendo.data.DataSource({
             transport: {
                 read: {
                     url: "@Url.Action("GetMsgDetails", "OutMessage")" + "?msgId=" + msgId,
                     dataType: "json",
                 },
             },
             batch: true,
         }),
         editable: "popup",
         columns: [
            { field: "Id", title: "Id", width: 250, hidden: true },
            { field: "Data", title: "Message Body", width: 100 },
           { field: "mobile", title: "Mobile Number", width: 100 },
         ]
     });
});

If you want to restrict user to give blank space in the name just create a if statement and give the condition. like I did:

$j('#fragment_key').bind({
    keypress: function(e){
        var key = e.keyCode;
    var character = String.fromCharCode(key); 
    if(character.match( /[' ']/)) {
        alert("Blank space is not allowed in the Name");
        return false;
        }
    }
});

• create a JQuery function .
• this is key press event.
• Initialize a variable.
• Give condition to match the character
• show a alert message for your matched condition.

Depending. If the order of keys in the object are not of importance, and I don't need to know the prototypes of the said object. Using always do the job.

const object = {};
JSON.stringify(object) === "{}" will pass but {} === "{}" will not

use command with sudo,

sudo apt-get autoremove --purge mongodb

OR

sudo apt-get remove mongodb* --purge

It will remove complete mongodb

It looks like it is an extension method (in System.Net.Http.Formatting):

HttpContentExtensions Class

Update:

PM> install-package Microsoft.AspNet.WebApi.Client

According to the System.Net.Http.Formatting NuGet package page, the System.Net.Http.Formatting package is now legacy and can instead be found in the Microsoft.AspNet.WebApi.Client package available on NuGet here.

Your query contains columns which could be present with the same name in more than one table you are referencing, hence the not unique error. It's best if you make the references explicit and/or use table aliases when joining.

Try

    SELECT pa.ProjectID, p.Project_Title, a.Account_ID, a.Username, a.Access_Type, c.First_Name, c.Last_Name
      FROM Project_Assigned pa
INNER JOIN Account a
        ON pa.AccountID = a.Account_ID
INNER JOIN Project p
        ON pa.ProjectID = p.Project_ID
INNER JOIN Clients c
        ON a.Account_ID = c.Account_ID
     WHERE a.Access_Type = 'Client';

document.body is not yet available when your code runs.

What you can do instead:

var docBody=document.getElementsByTagName("body")[0];
docBody.appendChild(mySpan);

I'm guessing that you want something like

SELECT tab1.a, tab2.b, tab3.c, tab4.d
  FROM table1 tab1 
       JOIN table2 tab2 ON (tab1.fg = tab2.fg)
       LEFT OUTER JOIN table4 tab4 ON (tab1.ss = tab4.ss)
       LEFT OUTER JOIN table3 tab3 ON (tab4.xya = tab3.xya and tab3.desc = 'XYZ')
       LEFT OUTER JOIN table5 tab5 on (tab4.kk = tab5.kk AND
                                       tab3.dd = tab5.dd)

That's not possible in a portable manner in pure C++, because it depends too much on the terminal used that may be connected with stdin (they are usually line buffered). You can, however use a library for that:

1. conio available with Windows compilers. Use the _getch() function to give you a character without waiting for the Enter key. I'm not a frequent Windows developer, but I've seen my classmates just include <conio.h> and use it. See conio.h at Wikipedia. It lists getch(), which is declared deprecated in Visual C++.

2. curses available for Linux. Compatible curses implementations are available for Windows too. It has also a getch() function. (try man getch to view its manpage). See Curses at Wikipedia.

I would recommend you to use curses if you aim for cross platform compatibility. That said, I'm sure there are functions that you can use to switch off line buffering (I believe that's called "raw mode", as opposed to "cooked mode" - look into man stty). Curses would handle that for you in a portable manner, if I'm not mistaken.

Display images and text paragraphs is not possible in a UITextView or UILabel, to this, you must use a UIWebView.

Just add the item in the storyboard, link to your code, and call it to load the URL.

In my particular case, I had a similar error on a legacy website used in my organization. To solve the issue, I had to list the website a a "Trusted site".

To do so:

• Click the Tools button, and then Internet options.
• Go on the Security tab.
• Click on Trusted sites and then on the sites button.
• Enter the url of the website and click on Add.

I'm leaving this here in the remote case it will help someone.

There's very powerful new package from genius data scientists at Win-Vector (folks that made vtreat, seplyr and replyr) called cdata. It implements "coordinated data" principles described in this document and also in this blog post. The idea is that regardless how you organize your data, it should be possible to identify individual data points using a system of "data coordinates". Here's a excerpt from the recent blog post by John Mount:

The whole system is based on two primitives or operators cdata::moveValuesToRowsD() and cdata::moveValuesToColumnsD(). These operators have pivot, un-pivot, one-hot encode, transpose, moving multiple rows and columns, and many other transforms as simple special cases.

It is easy to write many different operations in terms of the cdata primitives. These operators can work-in memory or at big data scale (with databases and Apache Spark; for big data use the cdata::moveValuesToRowsN() and cdata::moveValuesToColumnsN() variants). The transforms are controlled by a control table that itself is a diagram of (or picture of) the transform.

We will first build the control table (see blog post for details) and then perform the move of data from rows to columns.

library(cdata)
# first build the control table
pivotControlTable <- buildPivotControlTableD(table = dat1, # reference to dataset
                        columnToTakeKeysFrom = 'numbers', # this will become column headers
                        columnToTakeValuesFrom = 'value', # this contains data
                        sep="_")                          # optional for making column names

# perform the move of data to columns
dat_wide <- moveValuesToColumnsD(tallTable =  dat1, # reference to dataset
                    keyColumns = c('name'),         # this(these) column(s) should stay untouched 
                    controlTable = pivotControlTable# control table above
                    ) 
dat_wide

#>         name  numbers_1  numbers_2  numbers_3  numbers_4
#> 1  firstName  0.3407997 -0.7033403 -0.3795377 -0.7460474
#> 2 secondName -0.8981073 -0.3347941 -0.5013782 -0.1745357

Instead of initializing the variables with arbitrary values (for example int smallest = 9999, largest = 0) it is safer to initialize the variables with the largest and smallest values representable by that number type (that is int smallest = Integer.MAX_VALUE, largest = Integer.MIN_VALUE).

Since your integer array cannot contain a value larger than Integer.MAX_VALUE and smaller than Integer.MIN_VALUE your code works across all edge cases.

I solved the problem by following the instructions on msdn.microsoft.com more closely. There, it is stated that one must create the new macro by selecting Developer -> Macros, typing a new macro name, and clicking "Create". Creating the macro in this way, I was able to run it (see message box below).

Try this

string result;
if ( (!string.IsNullOrEmpty(phoneNumber)) && (phoneNumber.Length >= 10 ) )
    result = string.Format("{0:(###)###-"+new string('#',phoneNumber.Length-6)+"}",
    Convert.ToInt64(phoneNumber)
    );
else
    result = phoneNumber;
return result;

Cheers.

Just wanted to point out, as I struggled with this for a bit

def f(x):
    if x < 0:
        x = 0
    elif x > 100000:
        x = 100000
    return x

df.applymap(f)
df.describe()

this does not modify the dataframe itself, has to be reassigned

df = df.applymap(f)
df.describe()

I had the same problem. Everything works in VS2010 but when I run the same project in VS2008 I get the mentioned exception.

What I did in my VS2008 project to make it work was adding a call to the AddServiceEndpoint member of my ServiceHost object.

Here is my code snippet:

Uri baseAddress = new Uri("http://localhost:8195/v2/SystemCallbackListener");

ServiceHost host = new ServiceHost(typeof(SystemCallbackListenerImpl), baseAddress);

host.AddServiceEndpoint(typeof(CsfServiceReference.SystemCallbackListener),
                        new BasicHttpBinding(),
                        baseAddress);
host.Open();

I didn't modify the app.config file. But I guess the service endpoint could also have been added in the .config file.

No regex, so no need for //.

this should work:

$str = str_replace("\\", '/', $str);

You need to escape "\" as well.

You can use the fingerprintJS2 library, it helps a lot with calculating a browser fingerprint.

By the way, on Panopticlick you can see how unique this usually is.

Since Support for the ADT in Eclipse has ended, we have to use Android Studio.

You can set "access plus 1 seconds" and that way it will refresh the next time the user enters the site. Keep the setting for one month.

To use IN, you must have a set, use this syntax instead:

SELECT * FROM Table1 WHERE Table1.principal NOT IN (SELECT principal FROM table2)

A well-explained answer is already given by @mkobit, but I will add a big picture of the range key and hash key.

In a simple words range + hash key = composite primary key CoreComponents of Dynamodb

A primary key is consists of a hash key and an optional range key. Hash key is used to select the DynamoDB partition. Partitions are parts of the table data. Range keys are used to sort the items in the partition, if they exist.

So both have a different purpose and together help to do complex query. In the above example hashkey1 can have multiple n-range. Another example of range and hashkey is game, userA(hashkey) can play Ngame(range)

The Music table described in Tables, Items, and Attributes is an example of a table with a composite primary key (Artist and SongTitle). You can access any item in the Music table directly, if you provide the Artist and SongTitle values for that item.

A composite primary key gives you additional flexibility when querying data. For example, if you provide only the value for Artist, DynamoDB retrieves all of the songs by that artist. To retrieve only a subset of songs by a particular artist, you can provide a value for Artist along with a range of values for SongTitle.

In Supervised Learning we know what the input and output should be. For example , given a set of cars. We have to find out which ones red and which ones blue.

Whereas, Unsupervised learning is where we have to find out the answer with a very little or without any idea about how the output should be. For example, a learner might be able to build a model that detects when people are smiling based on correlation of facial patterns and words such as "what are you smiling about?".

Use case wise the following seem to be easy to use and fast. Just set the page number.

use AdventureWorks
DECLARE @RowsPerPage INT = 10, @PageNumber INT = 6;
with result as(
SELECT SalesOrderDetailID, SalesOrderID, ProductID,
ROW_NUMBER() OVER (ORDER BY SalesOrderDetailID) AS RowNum
FROM Sales.SalesOrderDetail
where 1=1
)
select SalesOrderDetailID, SalesOrderID, ProductID from result
WHERE result.RowNum BETWEEN ((@PageNumber-1)*@RowsPerPage)+1
AND @RowsPerPage*(@PageNumber)

also without CTE

use AdventureWorks
DECLARE @RowsPerPage INT = 10, @PageNumber INT = 6
SELECT SalesOrderDetailID, SalesOrderID, ProductID
FROM (
SELECT SalesOrderDetailID, SalesOrderID, ProductID,
ROW_NUMBER() OVER (ORDER BY SalesOrderDetailID) AS RowNum
FROM Sales.SalesOrderDetail
where 1=1
 ) AS SOD
WHERE SOD.RowNum BETWEEN ((@PageNumber-1)*@RowsPerPage)+1
AND @RowsPerPage*(@PageNumber)

The best way is to use a List within a List:

List<List<String>> listOfLists = new ArrayList<List<String>>();  

To make values empty you can do the following:

 $("#element").val('');

To get the selected value you can do:

var value = $("#element").val();

Where #element is the id of the element you wish to select.

Maybe this will help someone else, but I've seen this error when the RHS of the mapping contains a colon without enclosing quotes, such as:

someKey: another key: Change to make today: work out more

should be

someKey: another key: "Change to make today: work out more"

(Neither IN nor ANY is an "operator". A "construct" or "syntax element".)

Logically, quoting the manual:

IN is equivalent to = ANY.

But there are two syntax variants of IN and two variants of ANY. Details:

• How to use ANY instead of IN in a WHERE clause with Rails?

IN taking a set is equivalent to = ANY taking a set, as demonstrated here:

• postgreSQL - in vs any

But the second variant of each is not equivalent to the other. The second variant of the ANY construct takes an array (must be an actual array type), while the second variant of IN takes a comma-separated list of values. This leads to different restrictions in passing values and can also lead to different query plans in special cases:

• Index not used with =any() but used with in
• Pass multiple sets or arrays of values to a function

ANY is more versatile

The ANY construct is far more versatile, as it can be combined with various operators, not just =. Example:

SELECT 'foo' LIKE ANY('{FOO,bar,%oo%}');

For a big number of values, providing a set scales better for each:

• Optimizing a Postgres query with a large IN

Inversion / opposite / exclusion

"Find rows where id is in the given array":

SELECT * FROM tbl WHERE id = ANY (ARRAY[1, 2]);

Inversion: "Find rows where id is not in the array":

SELECT * FROM tbl WHERE id <> ALL (ARRAY[1, 2]);
SELECT * FROM tbl WHERE id <> ALL ('{1, 2}');  -- equivalent array literal
SELECT * FROM tbl WHERE NOT (id = ANY ('{1, 2}'));

All three equivalent. The first with array constructor, the other two with array literal. The data type can be derived from context unambiguously. Else, an explicit cast may be required, like '{1,2}'::int[].

Rows with id IS NULL do not pass either of these expressions. To include NULL values additionally:

SELECT * FROM tbl WHERE (id = ANY ('{1, 2}')) IS NOT TRUE;

Let's talk about copying objects in C++.

Test t;, calls the default constructor, which allocates a new array of integers. This is fine, and your expected behavior.

Trouble comes when you push t into your queue using q.push(t). If you're familiar with Java, C#, or almost any other object-oriented language, you might expect the object you created earler to be added to the queue, but C++ doesn't work that way.

When we take a look at std::queue::push method, we see that the element that gets added to the queue is "initialized to a copy of x." It's actually a brand new object that uses the copy constructor to duplicate every member of your original Test object to make a new Test.

Your C++ compiler generates a copy constructor for you by default! That's pretty handy, but causes problems with pointer members. In your example, remember that int *myArray is just a memory address; when the value of myArray is copied from the old object to the new one, you'll now have two objects pointing to the same array in memory. This isn't intrinsically bad, but the destructor will then try to delete the same array twice, hence the "double free or corruption" runtime error.

How do I fix it?

The first step is to implement a copy constructor, which can safely copy the data from one object to another. For simplicity, it could look something like this:

Test(const Test& other){
    myArray = new int[10];
    memcpy( myArray, other.myArray, 10 );
}

Now when you're copying Test objects, a new array will be allocated for the new object, and the values of the array will be copied as well.

We're not completely out trouble yet, though. There's another method that the compiler generates for you that could lead to similar problems - assignment. The difference is that with assignment, we already have an existing object whose memory needs to be managed appropriately. Here's a basic assignment operator implementation:

Test& operator= (const Test& other){
    if (this != &other) {
        memcpy( myArray, other.myArray, 10 );
    }
    return *this;
}

The important part here is that we're copying the data from the other array into this object's array, keeping each object's memory separate. We also have a check for self-assignment; otherwise, we'd be copying from ourselves to ourselves, which may throw an error (not sure what it's supposed to do). If we were deleting and allocating more memory, the self-assignment check prevents us from deleting memory from which we need to copy.

If this JSON file won't become too big over time, you should try:

1. Create a JavaScript object with the table array in it

   var obj = {
      table: []
   };
   

2. Add some data to it, for example:

   obj.table.push({id: 1, square:2});
   

3. Convert it from an object to a string with JSON.stringify

   var json = JSON.stringify(obj);
   

4. Use fs to write the file to disk

   var fs = require('fs');
   fs.writeFile('myjsonfile.json', json, 'utf8', callback);
   

5. If you want to append it, read the JSON file and convert it back to an object

   fs.readFile('myjsonfile.json', 'utf8', function readFileCallback(err, data){
       if (err){
           console.log(err);
       } else {
       obj = JSON.parse(data); //now it an object
       obj.table.push({id: 2, square:3}); //add some data
       json = JSON.stringify(obj); //convert it back to json
       fs.writeFile('myjsonfile.json', json, 'utf8', callback); // write it back 
   }});
   

This will work for data that is up to 100 MB effectively. Over this limit, you should use a database engine.

UPDATE:

Create a function which returns the current date (year+month+day) as a string. Create the file named this string + .json. the fs module has a function which can check for file existence named fs.stat(path, callback). With this, you can check if the file exists. If it exists, use the read function if it's not, use the create function. Use the date string as the path cuz the file will be named as the today date + .json. the callback will contain a stats object which will be null if the file does not exist.

The documentation of MySQL says :

CREATE DATABASE creates a database with the given name. To use this statement, you need the CREATE privilege for the database. CREATE SCHEMA is a synonym for CREATE DATABASE as of MySQL 5.0.2.

So, it would seem normal that those two instruction do the same.

You can continue using WebClient to POST (instead of GET, which is the HTTP verb you're currently using with DownloadString), but I think you'll find it easier to work with the (slightly) lower-level classes WebRequest and WebResponse.

There are two parts to this - the first is to post the login form, the second is recovering the "Set-cookie" header and sending that back to the server as "Cookie" along with your GET request. The server will use this cookie to identify you from now on (assuming it's using cookie-based authentication which I'm fairly confident it is as that page returns a Set-cookie header which includes "PHPSESSID").

POSTing to the login form

Form posts are easy to simulate, it's just a case of formatting your post data as follows:

field1=value1&field2=value2

Using WebRequest and code I adapted from Scott Hanselman, here's how you'd POST form data to your login form:

string formUrl = "http://www.mmoinn.com/index.do?PageModule=UsersAction&Action=UsersLogin"; // NOTE: This is the URL the form POSTs to, not the URL of the form (you can find this in the "action" attribute of the HTML's form tag
string formParams = string.Format("email_address={0}&password={1}", "your email", "your password");
string cookieHeader;
WebRequest req = WebRequest.Create(formUrl);
req.ContentType = "application/x-www-form-urlencoded";
req.Method = "POST";
byte[] bytes = Encoding.ASCII.GetBytes(formParams);
req.ContentLength = bytes.Length;
using (Stream os = req.GetRequestStream())
{
    os.Write(bytes, 0, bytes.Length);
}
WebResponse resp = req.GetResponse();
cookieHeader = resp.Headers["Set-cookie"];

Here's an example of what you should see in the Set-cookie header for your login form:

PHPSESSID=c4812cffcf2c45e0357a5a93c137642e; path=/; domain=.mmoinn.com,wowmine_referer=directenter; path=/; domain=.mmoinn.com,lang=en; path=/;domain=.mmoinn.com,adt_usertype=other,adt_host=-

GETting the page behind the login form

Now you can perform your GET request to a page that you need to be logged in for.

string pageSource;
string getUrl = "the url of the page behind the login";
WebRequest getRequest = WebRequest.Create(getUrl);
getRequest.Headers.Add("Cookie", cookieHeader);
WebResponse getResponse = getRequest.GetResponse();
using (StreamReader sr = new StreamReader(getResponse.GetResponseStream()))
{
    pageSource = sr.ReadToEnd();
}

EDIT:

If you need to view the results of the first POST, you can recover the HTML it returned with:

using (StreamReader sr = new StreamReader(resp.GetResponseStream()))
{
    pageSource = sr.ReadToEnd();
}

Place this directly below cookieHeader = resp.Headers["Set-cookie"]; and then inspect the string held in pageSource.

Okay - sandbox is off, domain has to be correct because 99% of the users can reach the app, and "all its live features available to the general public" is set to yes.

The accepted answer is very old.

I found a better modern answer here:

https://kevinmccarthy.org/2016/07/25/streaming-subprocess-stdin-and-stdout-with-asyncio-in-python/

and made some changes:

1. make it work on windows
2. make it work with multiple commands

import sys
import asyncio

if sys.platform == "win32":
    asyncio.set_event_loop_policy(asyncio.WindowsProactorEventLoopPolicy())


async def _read_stream(stream, cb):
    while True:
        line = await stream.readline()
        if line:
            cb(line)
        else:
            break


async def _stream_subprocess(cmd, stdout_cb, stderr_cb):
    try:
        process = await asyncio.create_subprocess_exec(
            *cmd, stdout=asyncio.subprocess.PIPE, stderr=asyncio.subprocess.PIPE
        )

        await asyncio.wait(
            [
                _read_stream(process.stdout, stdout_cb),
                _read_stream(process.stderr, stderr_cb),
            ]
        )
        rc = await process.wait()
        return process.pid, rc
    except OSError as e:
        # the program will hang if we let any exception propagate
        return e


def execute(*aws):
    """ run the given coroutines in an asyncio loop
    returns a list containing the values returned from each coroutine.
    """
    loop = asyncio.get_event_loop()
    rc = loop.run_until_complete(asyncio.gather(*aws))
    loop.close()
    return rc


def printer(label):
    def pr(*args, **kw):
        print(label, *args, **kw)

    return pr


def name_it(start=0, template="s{}"):
    """a simple generator for task names
    """
    while True:
        yield template.format(start)
        start += 1


def runners(cmds):
    """
    cmds is a list of commands to excecute as subprocesses
    each item is a list appropriate for use by subprocess.call
    """
    next_name = name_it().__next__
    for cmd in cmds:
        name = next_name()
        out = printer(f"{name}.stdout")
        err = printer(f"{name}.stderr")
        yield _stream_subprocess(cmd, out, err)


if __name__ == "__main__":
    cmds = (
        [
            "sh",
            "-c",
            """echo "$SHELL"-stdout && sleep 1 && echo stderr 1>&2 && sleep 1 && echo done""",
        ],
        [
            "bash",
            "-c",
            "echo 'hello, Dave.' && sleep 1 && echo dave_err 1>&2 && sleep 1 && echo done",
        ],
        [sys.executable, "-c", 'print("hello from python");import sys;sys.exit(2)'],
    )

    print(execute(*runners(cmds)))

It is unlikely that the example commands will work perfectly on your system, and it doesn't handle weird errors, but this code does demonstrate one way to run multiple subprocesses using asyncio and stream the output.

double formattedNumber = Double.parseDouble(new DecimalFormat("#.##").format(unformattedNumber));

worked for me :)

1st put "yourmp3file".mp3 file in the raw folder(ie inside Res folder)

2nd in your code put..

Notification noti = new Notification.Builder(this)
.setSound(Uri.parse("android.resource://" + v.getContext().getPackageName() + "/" + R.raw.yourmp3file))//*see note

This is what i put inside my onClick(View v) as only "context().getPackageName()" wont work from there as it wont get any context

1. Implement a slot in your QMainWindow where you will open your new Window,
2. Place a widget on your QMainWindow,
3. Connect a signal from this widget to a slot from the QMainWindow (for example: if the widget is a QPushButton connect the signal click() to the QMainWindow custom slot you have created).

Code example:

MainWindow.h

// ...
include "newwindow.h"
// ...
public slots:
   void openNewWindow();
// ...
private:
   NewWindow *mMyNewWindow;
// ...
}

MainWindow.cpp

// ...
   MainWindow::MainWindow()
   {
      // ...
      connect(mMyButton, SIGNAL(click()), this, SLOT(openNewWindow()));
      // ...
   }
// ...
void MainWindow::openNewWindow()
{
   mMyNewWindow = new NewWindow(); // Be sure to destroy your window somewhere
   mMyNewWindow->show();
   // ...
}

This is an example on how display a custom new window. There are a lot of ways to do this.

use the variable, Oracle does not support SQL in that context without an INTO. With a properly named variable your code will be more legible anyway.

If you are in need of specific implementation for sorting algorithms, data structures or anything that have a link to the above, could I recommend you the excellent "Data Structures and Algorithms" project on CodePlex?

It will have everything you need without reinventing the wheel.

Just my little grain of salt.

Another way to find out if a program is installed is by using the which command. It will show the path of the program you're searching for. For example if when your searching for apache you can use the following command:

$ which apache2ctl
/usr/sbin/apache2ctl

And if you searching for PHP try this:

$ which php
/usr/bin/php

If the which command doesn't give any result it means the software is not installed (or is not in the current $PATH):

$ which php
$

To highlight a few points:

The docs recommend using an install environment: https://conda.io/docs/user-guide/install/download.html#choosing-a-version-of-anaconda-or-miniconda

The version archive is here: https://repo.continuum.io/archive/

The version history is here: https://docs.anaconda.com/anaconda/release-notes

"Anaconda3 then its python 3.x and if it is Anaconda2 then its 2.x" - +1 papbiceps

The version archive is sorted newest at the top, but Anaconda2 ABOVE Anaconda3.

I use macros defined in a header file to handle bit set and clear:

/* a=target variable, b=bit number to act upon 0-n */
#define BIT_SET(a,b) ((a) |= (1ULL<<(b)))
#define BIT_CLEAR(a,b) ((a) &= ~(1ULL<<(b)))
#define BIT_FLIP(a,b) ((a) ^= (1ULL<<(b)))
#define BIT_CHECK(a,b) (!!((a) & (1ULL<<(b))))        // '!!' to make sure this returns 0 or 1

/* x=target variable, y=mask */
#define BITMASK_SET(x,y) ((x) |= (y))
#define BITMASK_CLEAR(x,y) ((x) &= (~(y)))
#define BITMASK_FLIP(x,y) ((x) ^= (y))
#define BITMASK_CHECK_ALL(x,y) (!(~(x) & (y)))
#define BITMASK_CHECK_ANY(x,y) ((x) & (y))

Python and just about every other computer language use the same principles as (I hope) you would use when finding a word in a printed dictionary:

(1) Depending on the human language involved, you have a notion of character ordering: 'a' < 'b' < 'c' etc

(2) First character has more weight than second character: 'az' < 'za' (whether the language is written left-to-right or right-to-left or boustrophedon is quite irrelevant)

(3) If you run out of characters to test, the shorter string is less than the longer string: 'foo' < 'food'

Typically, in a computer language the "notion of character ordering" is rather primitive: each character has a human-language-independent number ord(character) and characters are compared and sorted using that number. Often that ordering is not appropriate to the human language of the user, and then you need to get into "collating", a fun topic.

Take a look at the ISNULL function. It helps you replace NULL values for other values. http://msdn.microsoft.com/en-us/library/ms184325.aspx

This change worked for me:

// The size returned by CGImageGetWidth(imgRef) & CGImageGetHeight(imgRef) is incorrect as it doesn't respect the image orientation!
// CGImageRef imgRef = [image CGImage];
// CGFloat width = CGImageGetWidth(imgRef);
// CGFloat height = CGImageGetHeight(imgRef);
//
// This returns the actual width and height of the photo (and hence solves the problem
CGFloat width = image.size.width; 
CGFloat height = image.size.height;
CGRect bounds = CGRectMake(0, 0, width, height);

In most cases you have to initialize the array,

let list: number[] = [];

MySQL has a SQL query "SHOW INDEX FROM" which returns the indexes from a table. For eg. - the following query will show all the indexes for the products table:-

SHOW INDEXES FROM products \G

It returns a table with type, column_name, Key_name, etc. and displays output with all indexes and primary keys as -

*************************** 1. row ***************************
        Table: products
   Non_unique: 0
     Key_name: PRIMARY
 Seq_in_index: 1
  Column_name: product_id
    Collation: A
  Cardinality: 0
     Sub_part: NULL
       Packed: NULL
         Null: 
   Index_type: BTREE
      Comment: 
Index_comment: 

To just display primary key from the table use :-

SHOW INDEXES FROM table_name WHERE Key_name = 'PRIMARY'

SELECT chargeId, chargeType, MAX(serviceMonth) AS serviceMonth 
FROM invoice
GROUP BY chargeId, chargeType

I had the same exception installing using correct framework.

My solution was running cmd as administrator .... then it worked fine.

String stringWithQuates = "\""+ "your,comma,separated,string" + "\"";

this will retain the comma in CSV file

I had this issue for dependencies that were created in other projects. Downloaded thirdparty dependencies showed up fine in the build path, but not a library that I had created.

SOLUTION: In the project that is not building correctly,

• Right-click on the project and choose Properties, and then Maven.

• Uncheck the box labeled "Resolve dependencies from Workspace projects"

• Hit Apply, and then OK.

• Right-click again on your project and do a Maven->Update Snapshots (or Update Dependencies)

And your errors should go away when your project rebuilds (automatically if you have auto-build enabled).

A hex color code is #RRGGBB

RR, GG, BB are hex values ranging from 0-255

Let's call RR XY where X and Y are hex character 0-9A-F, A=10, F=15

The decimal value is X*16+Y

If RR = B7, the decimal for B is 11, so value is 11*16 + 7 = 183

public int[] getRGB(String rgb){
    int[] ret = new int[3];
    for(int i=0; i<3; i++){
        ret[i] = hexToInt(rgb.charAt(i*2), rgb.charAt(i*2+1));
    }
    return ret;
}

public int hexToInt(char a, char b){
    int x = a < 65 ? a-48 : a-55;
    int y = b < 65 ? b-48 : b-55;
    return x*16+y;
}

SIMPLE SOLUTION

File file = new File("F:/ABC.TXT");
FileWriter fileWriter = new FileWriter(file,true);
filewriter.write("\r\n");

And if you do that very often, you could use a ViewSwitcher or a ViewFlipper to ease view substitution.

I spent the entire morning solving a similar problem after having landed on this stack question. I used Dan's first solution in the answer above as the jump off point.

Problem

I have a dev (this is on my local machine), staging, and production environment. My staging and production environments live on the same server.

The app is deployed to staging via acmeserver/~staging/note-taking-app and the production version lives at acmeserver/note-taking-app (blame IT).

All the media files such as fonts were loading perfectly fine on dev (i.e., react-scripts start).

However, when I created and uploaded staging and production builds, while the .css and .js files were loading properly, fonts were not. The compiled .css file looked to have a correct path but the browser http request was getting some very wrong pathing (shown below).

The compiled main.fc70b10f.chunk.css file:

@font-face {
  font-family: SairaStencilOne-Regular;
  src: url(note-taking-app/static/media/SairaStencilOne-Regular.ca2c4b9f.ttf) ("truetype");
}

The browser http request is shown below. Note how it is adding in /static/css/ when the font file just lives in /static/media/ as well as duplicating the destination folder. I ruled out the server config being the culprit.

The Referer is partly at fault too.

GET /~staging/note-taking-app/static/css/note-taking-app/static/media/SairaStencilOne-Regular.ca2c4b9f.ttf HTTP/1.1
Host: acmeserver
Origin: http://acmeserver
Referer: http://acmeserver/~staging/note-taking-app/static/css/main.fc70b10f.chunk.css

The package.json file had the homepage property set to ./note-taking-app. This was causing the problem.

{
  "name": "note-taking-app",
  "version": "0.1.0",
  "private": true,
  "homepage": "./note-taking-app",
  "scripts": {
    "start": "env-cmd -e development react-scripts start",
    "build": "react-scripts build",
    "build:staging": "env-cmd -e staging npm run build",
    "build:production": "env-cmd -e production npm run build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  }
  //...
}

Solution

That was long winded — but the solution is to:

1. change the PUBLIC_URL env variable depending on the environment
2. remove the homepage property from the package.json file

Below is my .env-cmdrc file. I use .env-cmdrc over regular .env because it keeps everything together in one file.

{
  "development": {
    "PUBLIC_URL": "",
    "REACT_APP_API": "http://acmeserver/~staging/note-taking-app/api"
  },
  "staging": {
    "PUBLIC_URL": "/~staging/note-taking-app",
    "REACT_APP_API": "http://acmeserver/~staging/note-taking-app/api"
  },
  "production": {
    "PUBLIC_URL": "/note-taking-app",
    "REACT_APP_API": "http://acmeserver/note-taking-app/api"
  }
}

Routing via react-router-dom works fine too — simply use the PUBLIC_URL env variable as the basename property.

import React from "react";
import { BrowserRouter } from "react-router-dom";

const createRouter = RootComponent => (
  <BrowserRouter basename={process.env.PUBLIC_URL}>
    <RootComponent />
  </BrowserRouter>
);

export { createRouter };

The server config is set to route all requests to the ./index.html file.

Finally, here is what the compiled main.fc70b10f.chunk.css file looks like after the discussed changes were implemented.

@font-face {
  font-family: SairaStencilOne-Regular;
  src: url(/~staging/note-taking-app/static/media/SairaStencilOne-Regular.ca2c4b9f.ttf)
    format("truetype");
}

    Create React App assumes your application is hosted at the serving web server's root or a subpath as specified in package.json (homepage). Normally, Create React App ignores the hostname. You may use this variable to force assets to be referenced verbatim to the url you provide (hostname included). This may be particularly useful when using a CDN to host your application.

What is yield?

The yield keyword returns data from a generator function:

The heart of a generator function is the yield keyword. In its simplest form, a yield statement looks much like a return statement, except that instead of stopping execution of the function and returning, yield instead provides a value to the code looping over the generator and pauses execution of the generator function.

What is a generator function?

A generator function is effectively a more compact and efficient way to write an Iterator. It allows you to define a function (your xrange) that will calculate and return values while you are looping over it:

function xrange($min, $max) {
    for ($i = $min; $i <= $max; $i++) {
        yield $i;
    }
}

[…]

foreach (xrange(1, 10) as $key => $value) {
    echo "$key => $value", PHP_EOL;
}

This would create the following output:

0 => 1
1 => 2
…
9 => 10

You can also control the $key in the foreach by using

yield $someKey => $someValue;

In the generator function, $someKey is whatever you want appear for $key and $someValue being the value in $val. In the question's example that's $i.

What's the difference to normal functions?

Now you might wonder why we are not simply using PHP's native range function to achieve that output. And right you are. The output would be the same. The difference is how we got there.

When we use range PHP, will execute it, create the entire array of numbers in memory and return that entire array to the foreach loop which will then go over it and output the values. In other words, the foreach will operate on the array itself. The range function and the foreach only "talk" once. Think of it like getting a package in the mail. The delivery guy will hand you the package and leave. And then you unwrap the entire package, taking out whatever is in there.

When we use the generator function, PHP will step into the function and execute it until it either meets the end or a yield keyword. When it meets a yield, it will then return whatever is the value at that time to the outer loop. Then it goes back into the generator function and continues from where it yielded. Since your xrange holds a for loop, it will execute and yield until $max was reached. Think of it like the foreach and the generator playing ping pong.

Why do I need that?

Obviously, generators can be used to work around memory limits. Depending on your environment, doing a range(1, 1000000) will fatal your script whereas the same with a generator will just work fine. Or as Wikipedia puts it:

Because generators compute their yielded values only on demand, they are useful for representing sequences that would be expensive or impossible to compute at once. These include e.g. infinite sequences and live data streams.

Generators are also supposed to be pretty fast. But keep in mind that when we are talking about fast, we are usually talking in very small numbers. So before you now run off and change all your code to use generators, do a benchmark to see where it makes sense.

Another Use Case for Generators is asynchronous coroutines. The yield keyword does not only return values but it also accepts them. For details on this, see the two excellent blog posts linked below.

Since when can I use yield?

Generators have been introduced in PHP 5.5. Trying to use yield before that version will result in various parse errors, depending on the code that follows the keyword. So if you get a parse error from that code, update your PHP.

num * -1

This would do it for you.

TLS client certificates are not sent in HTTP headers. They are transmitted by the client as part of the TLS handshake, and the server will typically check the validity of the certificate during the handshake as well.

If the certificate is accepted, most web servers can be configured to add headers for transmitting the certificate or information contained on the certificate to the application. Environment variables are populated with certificate information in Apache and Nginx which can be used in other directives for setting headers.

As an example of this approach, the following Nginx config snippet will validate a client certificate, and then set the SSL_CLIENT_CERT header to pass the entire certificate to the application. This will only be set when then certificate was successfully validated, so the application can then parse the certificate and rely on the information it bears.

server {
    listen 443 ssl;
    server_name example.com;
    ssl_certificate /path/to/chainedcert.pem;  # server certificate
    ssl_certificate_key /path/to/key;          # server key

    ssl_client_certificate /path/to/ca.pem;    # client CA
    ssl_verify_client on;
    proxy_set_header SSL_CLIENT_CERT $ssl_client_cert;

    location / {
        proxy_pass http://localhost:3000;
    }
}

Just use the constructor for the vector that takes iterators:

std::set<T> s;

//...

std::vector v( s.begin(), s.end() );

Assumes you just want the content of s in v, and there's nothing in v prior to copying the data to it.

You can do this by creating a new image (also answered in your other posting of this question):

- (UIImage*)imageWithBorderFromImage:(UIImage*)source;
{
  CGSize size = [source size];
  UIGraphicsBeginImageContext(size);
  CGRect rect = CGRectMake(0, 0, size.width, size.height);
  [source drawInRect:rect blendMode:kCGBlendModeNormal alpha:1.0];

  CGContextRef context = UIGraphicsGetCurrentContext();
  CGContextSetRGBStrokeColor(context, 1.0, 0.5, 1.0, 1.0); 
  CGContextStrokeRect(context, rect);
  UIImage *testImg =  UIGraphicsGetImageFromCurrentImageContext();
  UIGraphicsEndImageContext();
  return testImg;
}  

This code will produce a pink border around the image. However if you are going to just display the border then use the layer of the UIImageView and set its border.

If response is an Array Buffer, try this under onsuccess event in Ajax:

 if (event.data instanceof ArrayBuffer) {
          var binary = '';
          var bytes = new Uint8Array(event.data);
          for (var i = 0; i < bytes.byteLength; i++) {
              binary += String.fromCharCode(bytes[i])
          }
          $("#some_id").append("<li><img src=\"data:image/png;base64," + window.btoa(binary) + "\"/></span></li>");
          return;
      }

• where event.data is response received in success function of xhr event.

you should have three tables: users, comments and comment_users.

comment_users has just two fields: fk_user_id and fk_comment_id

That way you can keep your performance up to a maximum :)

For questions on simple string manipulation the dir built-in function comes in handy. It gives you, among others, a list of methods of the argument, e.g., dir(s) returns a list containing upper.

LIMIT allow you to skip any number of rows. It has two parameters, and first of them - how many rows to skip

try out this..

document.getElementById("edName").required = true;

#include <string>
#include <cmath>
double _string_to_double(std::string s,unsigned short radix){
double n = 0;
for (unsigned short x = s.size(), y = 0;x>0;)
if(!(s[--x] ^ '.')) // if is equal
n/=pow(10,s.size()-1-x), y+= s.size()-x;
else
    n+=( (s[x]-48) * pow(10,s.size()-1-x - y) );
return n;
}

or

//In case you want to convert from different bases.
#include <string>
#include <iostream>
#include <cmath>
double _string_to_double(std::string s,unsigned short radix){
double n = 0;
for (unsigned short x = s.size(), y = 0;x>0;)
if(!(s[--x] ^ '.'))
n/=pow(radix,s.size()-1-x), y+= s.size()-x;
else
    n+=( (s[x]- (s[x]<='9' ? '0':'0'+7)   ) * pow(radix,s.size()-1-x - y) );
return n;
}
int main(){
std::cout<<_string_to_double("10.A",16)<<std::endl;//Prints 16.625
std::cout<<_string_to_double("1001.1",2)<<std::endl;//Prints 9.5
std::cout<<_string_to_double("123.4",10)<<std::endl;//Prints 123.4
return 0;
}

If you are doing this just for a parameter coming into a Stored Procedure, you can use the following:

declare @badIndex int
set @badIndex = PatIndex('%[^0-9]%', @Param)
while @badIndex > 0
    set @Param = Replace(@Param, Substring(@Param, @badIndex, 1), '')
    set @badIndex = PatIndex('%[^0-9]%', @Param)

'async': false says it's depreciated. I did notice if I run console.log('test1'); on ajax success, then console.log('test2'); in normal js after the ajax function, test2 prints before test1 so the issue is an ajax call has a small delay, but doesn't stop the rest of the function to get results. The variable simply, was not set "yet", so you need to delay the next function.

function runPHP(){
    var input = document.getElementById("input1");
    var result = 'failed to run php';

    $.ajax({ url: '/test.php',
        type: 'POST',
        data: {action: 'test'},
        success: function(data) {
            result = data;
        }
    });

    setTimeout(function(){
        console.log(result);
    }, 1000);
}

on test.php (incase you need to test this function)

function test(){
    print 'ran php';
}

if(isset($_POST['action']) && !empty($_POST['action'])) {
    $action = htmlentities($_POST['action']);
    switch($action) {
        case 'test' : test();break;
    }
}

You can do it with drop_duplicates as you wanted

# initialisation
d = pd.DataFrame({'A' : [1,1,2,3,3], 'B' : [2,2,7,4,4],  'C' : [1,4,1,0,8]})

d = d.sort_values("C", ascending=False)
d = d.drop_duplicates(["A","B"])

If it's important to get the same order

d = d.sort_index()

I want to stress on using

SET XACT_ABORT ON;

for the MSSQL transaction with multiple sql statements.

See: https://msdn.microsoft.com/en-us/library/ms188792.aspx They provide a very good example.

So, the final code should look like the following:

SET XACT_ABORT ON;

BEGIN TRANSACTION
   DECLARE @DataID int;
   INSERT INTO DataTable (Column1 ...) VALUES (....);
   SELECT @DataID = scope_identity();
   INSERT INTO LinkTable VALUES (@ObjectID, @DataID);
COMMIT

ETA 24 Apr 17 I wanted to simplify this a bit with some async/await magic, as it makes it a lot more succinct:

Using the same promisified-observable:

const startObservable = (domNode) => {
  var targetNode = domNode;

  var observerConfig = {
    attributes: true,
    childList: true,
    characterData: true
  };

  return new Promise((resolve) => {
      var observer = new MutationObserver(function (mutations) {
         // For the sake of...observation...let's output the mutation to console to see how this all works
         mutations.forEach(function (mutation) {
             console.log(mutation.type);
         });
         resolve(mutations)
     });
     observer.observe(targetNode, observerConfig);
   })
} 

Your calling function can be as simple as:

const waitForMutation = async () => {
    const button = document.querySelector('.some-button')
    if (button !== null) button.click()
    try {
      const results = await startObservable(someDomNode)
      return results
    } catch (err) { 
      console.error(err)
    }
}

If you wanted to add a timeout, you could use a simple Promise.race pattern as demonstrated here:

const waitForMutation = async (timeout = 5000 /*in ms*/) => {
    const button = document.querySelector('.some-button')
    if (button !== null) button.click()
    try {

      const results = await Promise.race([
          startObservable(someDomNode),
          // this will throw after the timeout, skipping 
          // the return & going to the catch block
          new Promise((resolve, reject) => setTimeout(
             reject, 
             timeout, 
             new Error('timed out waiting for mutation')
          )
       ])
      return results
    } catch (err) { 
      console.error(err)
    }
}

Original

You can do this without libraries, but you'd have to use some ES6 stuff, so be cognizant of compatibility issues (i.e., if your audience is mostly Amish, luddite or, worse, IE8 users)

First, we'll use the MutationObserver API to construct an observer object. We'll wrap this object in a promise, and resolve() when the callback is fired (h/t davidwalshblog)david walsh blog article on mutations:

const startObservable = (domNode) => {
    var targetNode = domNode;

    var observerConfig = {
        attributes: true,
        childList: true,
        characterData: true
    };

    return new Promise((resolve) => {
        var observer = new MutationObserver(function (mutations) {
            // For the sake of...observation...let's output the mutation to console to see how this all works
            mutations.forEach(function (mutation) {
                console.log(mutation.type);
            });
            resolve(mutations)
        });
        observer.observe(targetNode, observerConfig);
    })
} 

Then, we'll create a generator function. If you haven't used these yet, then you're missing out--but a brief synopsis is: it runs like a sync function, and when it finds a yield <Promise> expression, it waits in a non-blocking fashion for the promise to be fulfilled (Generators do more than this, but this is what we're interested in here).

// we'll declare our DOM node here, too
let targ = document.querySelector('#domNodeToWatch')

function* getMutation() {
    console.log("Starting")
    var mutations = yield startObservable(targ)
    console.log("done")
}

A tricky part about generators is they don't 'return' like a normal function. So, we'll use a helper function to be able to use the generator like a regular function. (again, h/t to dwb)

function runGenerator(g) {
    var it = g(), ret;

    // asynchronously iterate over generator
    (function iterate(val){
        ret = it.next( val );

        if (!ret.done) {
            // poor man's "is it a promise?" test
            if ("then" in ret.value) {
                // wait on the promise
                ret.value.then( iterate );
            }
            // immediate value: just send right back in
            else {
                // avoid synchronous recursion
                setTimeout( function(){
                    iterate( ret.value );
                }, 0 );
            }
        }
    })();
}

Then, at any point before the expected DOM mutation might happen, simply run runGenerator(getMutation).

Now you can integrate DOM mutations into a synchronous-style control flow. How bout that.

I am using searchform.php and search.php files as already mentioned, but here I provide the actual code.

Creating a Search Page codex page helps here and #Creating_a_Search_Page_Template shows the search query.

In my case I pass the $search_query arguments to the WP_Query Class (which can determine if is search query!). I then run The Loop to display the post information I want to, which in my case is the the_permalink and the_title.

Search box form:

<form class="search" method="get" action="<?php echo home_url(); ?>" role="search">
  <input type="search" class="search-field" placeholder="<?php echo esc_attr_x( 'Search …', 'placeholder' ) ?>" value="<?php echo get_search_query() ?>" name="s" title="<?php echo esc_attr_x( 'Search for:', 'label' ) ?>" />
  <button type="submit" role="button" class="btn btn-default right"/><span class="glyphicon glyphicon-search white"></span></button>
</form>

search.php template file:

<?php
    global $query_string;
    $query_args = explode("&", $query_string);
    $search_query = array();

    foreach($query_args as $key => $string) {
      $query_split = explode("=", $string);
      $search_query[$query_split[0]] = urldecode($query_split[1]);
    } // foreach

    $the_query = new WP_Query($search_query);
    if ( $the_query->have_posts() ) : 
    ?>
    <!-- the loop -->

    <ul>    
    <?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
        <li>
            <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
        </li>   
    <?php endwhile; ?>
    </ul>
    <!-- end of the loop -->

    <?php wp_reset_postdata(); ?>

<?php else : ?>
    <p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
<?php endif; ?>

On a sorted column, you can also try this idea:

B2=A2
B3=IFERROR(INDEX(A:A,MATCH(B2,A:A,1)+1),"")

B3 can be pasted down. It will result 0, after the last unique match. If this is unwanted, put some IF statement around to exclude this.

Edit:

Easier than an IF statement, at least for text-values:

B3=IFERROR(T(INDEX(A:A,MATCH(B2,A:A,1)+1)),"")

The IE9 developer tools worked for me. Just set the "Browser Mode" menu item to IE7.

Using Newton C++

bool exists_linear( INPUT_ITERATOR first, INPUT_ITERATOR last, const T& value )

bool exists_binary( INPUT_ITERATOR first, INPUT_ITERATOR last, const T& value )

the code will be something like this:

if ( newton::exists_linear(arr.begin(), arr.end(), value) )
   std::cout << "found" << std::endl;
else
   std::cout << "not found" << std::endl;

both exists_linear and exists_binary use std implementations. binary use std::binary_search, and linear use std::find, but return directly a bool, not an iterator.

Also, while installing Visual Studio 2013, ensure that you have checked "Web Developer Tools"

If you know the app id of the package (like org.mozilla.firefox), it is easy. First to get the path of actual package file of the appId,

$  adb shell pm list packages -f com.google.android.apps.inbox
package:/data/app/com.google.android.apps.inbox-1/base.apk=com.google.android.apps.inbox

Now you can do some grep|sed magic to extract the path : /data/app/com.google.android.apps.inbox-1/base.apk

After that aapt tool comes in handy :

$  adb shell aapt dump badging /data/app/com.google.android.apps.inbox-1/base.apk
...
application-label:'Inbox'
application-label-hi:'Inbox'
application-label-ru:'Inbox'
...

Again some grep magic to get the Label.

Pass by value - The function copies the variable and works with a copy(so it doesn't change anything in the original variable)

Pass by reference - The function uses the original variable, if you change the variable in the other function, it changes in the original variable too.

Example(copy and use/try this yourself and see) :

#include <iostream>

using namespace std;

void funct1(int a){ //pass-by-value
    a = 6; //now "a" is 6 only in funct1, but not in main or anywhere else
}
void funct2(int &a){ //pass-by-reference
    a = 7; //now "a" is 7 both in funct2, main and everywhere else it'll be used
}

int main()
{
    int a = 5;

    funct1(a);
    cout<<endl<<"A is currently "<<a<<endl<<endl; //will output 5
    funct2(a);
    cout<<endl<<"A is currently "<<a<<endl<<endl; //will output 7

    return 0;
}

Keep it simple, peeps. Walls of text can be a bad habit.

One octet is 8 bits. Content-length is the number of octets that the message body represents.

I have used this way lots time ...

@Component({_x000D_
   selector: "data",_x000D_
   template: "<h1>{{ getData() }}</h1>"_x000D_
})_x000D_
_x000D_
export class DataComponent{_x000D_
    this.http.get(path).subscribe({_x000D_
       DataComponent.setSubscribeData(res);_x000D_
    })_x000D_
}_x000D_
_x000D_
_x000D_
static subscribeData:any;_x000D_
static setSubscribeData(data):any{_x000D_
    DataComponent.subscribeData=data;_x000D_
    return data;_x000D_
}

use static keyword and save your time... here either you can use static variable or directly return object you want.... hope it will help you.. happy coding...

Cleaning the project solved my problem.

Steps: Product -> Clean(or Shift + Cmd + K)

you can use QString::fromAscii()

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

with data() returning a char*

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

PHP errors can be displayed by any of below methods:

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

I am pretty sure this is a duplicate. Anyway, have a look at the following piece of code

x <- seq(5, 15, length=1000)
y <- dnorm(x, mean=10, sd=3)
plot(x, y, type="l", lwd=1)

I'm sure you can work the rest out yourself, for the title you might want to look for something called main= and y-axis labels are also up to you.

If you want to see more of the tails of the distribution, why don't you try playing with the seq(5, 15, ) section? Finally, if you want to know more about what dnorm is doing I suggest you look here

The following works for springboot 1.3 and above:

As init.d service

The executable jar has the usual start, stop, restart, and status commands. It will also set up a PID file in the usual /var/run directory and logging in the usual /var/log directory by default.

You just need to symlink your jar into /etc/init.d like so

sudo link -s /var/myapp/myapp.jar /etc/init.d/myapp

OR

sudo ln -s ~/myproject/build/libs/myapp-1.0.jar /etc/init.d/myapp_servicename

After that you can do the usual

/etc/init.d/myapp start

Then setup a link in whichever runlevel you want the app to start/stop in on boot if so desired.

As a systemd service

To run a Spring Boot application installed in var/myapp you can add the following script in /etc/systemd/system/myapp.service:

[Unit]
Description=myapp
After=syslog.target

[Service]
ExecStart=/var/myapp/myapp.jar

[Install]
WantedBy=multi-user.target

NB: in case you are using this method, do not forget to make the jar file itself executable (with chmod +x) otherwise it will fail with error "Permission denied".

You could try using HTML5s sessionStorage it lasts for the duration on the page session. A page session lasts for as long as the browser is open and survives over page reloads and restores. Opening a page in a new tab or window will cause a new session to be initiated.

You have most of the code…

CURLOPT_HTTPHEADER for curl_setopt() takes an array with each header as an element. You have one element with multiple headers.

You also need to add the Authorization header to your $header array.

$header = array();
$header[] = 'Content-length: 0';
$header[] = 'Content-type: application/json';
$header[] = 'Authorization: OAuth SomeHugeOAuthaccess_tokenThatIReceivedAsAString';

Update: As of jQuery 1.4 you can use the .delay( n ) method. http://api.jquery.com/delay/

$('.notice').fadeIn().delay(2000).fadeOut('slow'); 

Note: $.show() and $.hide() by default are not queued, so if you want to use $.delay() with them, you need to configure them that way:

$('.notice')
    .show({duration: 0, queue: true})
    .delay(2000)
    .hide({duration: 0, queue: true});

You could possibly use the Queue syntax, this might work:

jQuery(function($){ 

var e = $('.notice'); 
e.fadeIn(); 
e.queue(function(){ 
  setTimeout(function(){ 
    e.dequeue(); 
  }, 2000 ); 
}); 
e.fadeOut('fast'); 

}); 

or you could be really ingenious and make a jQuery function to do it.

(function($){ 

  jQuery.fn.idle = function(time)
  { 
      var o = $(this); 
      o.queue(function()
      { 
         setTimeout(function()
         { 
            o.dequeue(); 
         }, time);
      });
  };
})(jQuery);

which would ( in theory , working on memory here ) permit you do to this:

$('.notice').fadeIn().idle(2000).fadeOut('slow'); 

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Test {
    public static void main(String[] args) {
        Pattern pattern = Pattern.compile(".*'([^']*)'.*");
        String mydata = "some string with 'the data i want' inside";

        Matcher matcher = pattern.matcher(mydata);
        if(matcher.matches()) {
            System.out.println(matcher.group(1));
        }

    }
}

I would like to post rather a Designer approach to this, this will keep design separate from your business logic:

Step 1. Create new style in (res->values->styles.xml) : Basically it is copy of your overall scheme with different parent - parent="Theme.AppCompat.Light.NoActionBar"

<!-- custom application theme. -->
    <style name="MarkitTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimary</item>
        <item name="colorAccent">@color/colorAccent</item>

        <item name="android:windowNoTitle">true</item>
    </style>

Step 2: In your AndroidManifest.xml, add this theme to the activity you want in: e.g. I want my main activity without action-bar so add this like below:

<activity android:name=".MainActivity"
            android:theme="@style/MarkitTheme">

This is the best solution for me after trying a lot of things.

Do not use float... It will round your coordinates, resulting in some strange occurrences.

Use decimal

Join on one-to-many relation in JPQL looks as follows:

select b.fname, b.lname from Users b JOIN b.groups c where c.groupName = :groupName 

When several properties are specified in select clause, result is returned as Object[]:

Object[] temp = (Object[]) em.createNamedQuery("...")
    .setParameter("groupName", groupName)
    .getSingleResult(); 
String fname = (String) temp[0];
String lname = (String) temp[1];

By the way, why your entities are named in plural form, it's confusing. If you want to have table names in plural, you may use @Table to specify the table name for the entity explicitly, so it doesn't interfere with reserved words:

@Entity @Table(name = "Users")     
public class User implements Serializable { ... } 

If you working with numpy, you can use the following solution which also works with negative numbers (it's also working on arrays)

import numpy as np
def round_down(num):
    if num < 0:
        return -np.ceil(abs(num))
    else:
        return np.int32(num)
round_down = np.vectorize(round_down)

round_down([-1.1, -1.5, -1.6, 0, 1.1, 1.5, 1.6])
> array([-2., -2., -2.,  0.,  1.,  1.,  1.])

I think it will also work if you just use the math module instead of numpy module.

Getting one month ago is easy with a single MySQL function:

SELECT DATE_SUB(NOW(), INTERVAL 1 MONTH);

or

SELECT NOW() - INTERVAL 1 MONTH;

Off the top of my head, I can't think of an elegant way to get the first day of last month in MySQL, but this will certainly work:

SELECT CONCAT(LEFT(NOW() - INTERVAL 1 MONTH,7),'-01');

Put them together and you get a query that solves your problem:

SELECT *
FROM your_table
WHERE t >= CONCAT(LEFT(NOW() - INTERVAL 1 MONTH,7),'-01')
AND t <= NOW() - INTERVAL 1 MONTH

For a single column better to use map(), like this:

df = pd.DataFrame([{'a': 15, 'b': 15, 'c': 5}, {'a': 20, 'b': 10, 'c': 7}, {'a': 25, 'b': 30, 'c': 9}])

    a   b  c
0  15  15  5
1  20  10  7
2  25  30  9



df['a'] = df['a'].map(lambda a: a / 2.)

      a   b  c
0   7.5  15  5
1  10.0  10  7
2  12.5  30  9

You probably don't want to do this:

#include "client.cpp"

A *.cpp file will have been compiled by the compiler as part of your build. By including it in other files, it will be compiled again (and again!) in every file in which you include it.

Now here's the thing: You are guarding it with #ifndef SOCKET_CLIENT_CLASS, however, each file that has #include "client.cpp" is built independently and as such will find SOCKET_CLIENT_CLASS not yet defined. Therefore it's contents will be included, not #ifdef'd out.

If it contains any definitions at all (rather than just declarations) then these definitions will be repeated in every file where it's included.

I found a tool "webchk” written in Python. Returns a status code for a list of urls. https://pypi.org/project/webchk/

Output looks like this:

? webchk -i ./dxieu.txt | grep '200'
http://salesforce-case-status.dxi.eu/login ... 200 OK (0.108)
https://support.dxi.eu/hc/en-gb ... 200 OK (0.389)
https://support.dxi.eu/hc/en-gb ... 200 OK (0.401)

Hope that helps!

We can use enum type for this.We don't require a library. For example

           enum {false,true};

the value for false will be 0 and the value for true will be 1.

Could have easily done using an extra level of Div.

<div style="background-color: blue; padding: 10px; position: relative; height: 100px;">
  <div style="position: absolute; left: 0px; right: 0px; bottom: 10px; padding:0px 10px;">
    <div style="background-color: gray;">css sux</div>
  </div>

Try this test:

any(substring in string for substring in substring_list)

It will return True if any of the substrings in substring_list is contained in string.

Note that there is a Python analogue of Marc Gravell's answer in the linked question:

from itertools import imap
any(imap(string.__contains__, substring_list)) 

In Python 3, you can use map directly instead:

any(map(string.__contains__, substring_list))

Probably the above version using a generator expression is more clear though.

Since Java 8:

List<String> myList = map.keySet().stream().collect(Collectors.toList());

rgl is great, but takes a bit of experimentation to get the axes right.

If you have a lot of points, why not take a random sample from them, and then plot the resulting surface. You can add several surfaces all based on samples from the same data to see if the process of sampling is horribly affecting your data.

So, here is a pretty horrible function but it does what I think you want it to do (but without the sampling). Given a matrix (x, y, z) where z is the heights it will plot both the points and also a surface. Limitations are that there can only be one z for each (x,y) pair. So planes which loop back over themselves will cause problems.

The plot_points = T will plot the individual points from which the surface is made - this is useful to check that the surface and the points actually meet up. The plot_contour = T will plot a 2d contour plot below the 3d visualization. Set colour to rainbow to give pretty colours, anything else will set it to grey, but then you can alter the function to give a custom palette. This does the trick for me anyway, but I'm sure that it can be tidied up and optimized. The verbose = T prints out a lot of output which I use to debug the function as and when it breaks.

plot_rgl_model_a <- function(fdata, plot_contour = T, plot_points = T, 
                             verbose = F, colour = "rainbow", smoother = F){
  ## takes a model in long form, in the format
  ## 1st column x
  ## 2nd is y,
  ## 3rd is z (height)
  ## and draws an rgl model

  ## includes a contour plot below and plots the points in blue
  ## if these are set to TRUE

  # note that x has to be ascending, followed by y
  if (verbose) print(head(fdata))

  fdata <- fdata[order(fdata[, 1], fdata[, 2]), ]
  if (verbose) print(head(fdata))
  ##

So my approach would be to, try to do it with all your data (I easily plot surfaces generated from ~15k points). If that doesn't work, take several smaller samples and plot them all at once using these functions.

One issue with your ContentLoader is that internally it operates sequentially. A better pattern is to parallelize the work and then sychronize at the end, so we get

public class PageViewModel : IHandle<SomeMessage>
{
   ...

   public async void Handle(SomeMessage message)
   {
      ShowLoadingAnimation();

      // makes UI very laggy, but still not dead
      await this.contentLoader.LoadContentAsync(); 

      HideLoadingAnimation();   
   }
}

public class ContentLoader 
{
    public async Task LoadContentAsync()
    {
        var tasks = new List<Task>();
        tasks.Add(DoCpuBoundWorkAsync());
        tasks.Add(DoIoBoundWorkAsync());
        tasks.Add(DoCpuBoundWorkAsync());
        tasks.Add(DoSomeOtherWorkAsync());

        await Task.WhenAll(tasks).ConfigureAwait(false);
    }
}

Obviously, this doesn't work if any of the tasks require data from other earlier tasks, but should give you better overall throughput for most scenarios.

What happens if you try the following?

Instead of your double REPLACE statement, try:

REPLACE(IFNULL(ts.description, ''),'\r\n', '\n')

Also, I think it should be LINES TERMINATED BY '\r\n' instead of just '\n'

In my case i just comment below line by opening .csproj file and did the trick

.<!-- <Import Project="..\PRPJECTNAME.targets" /> -->

My problem may be different but i am dragged here, but this may help someone.

I picked a single web project from my solution and try to open it as a stand alone project which was making issue, after above heck am able to solve issue.

1. Run this command

New-SelfSignedCertificate -certstorelocation cert:\localmachine\my -dnsname {your-site-hostname}

in powershell using admin rights, This will generate all certificates in Personal directory

2. To get rid of Privacy error, select these certificates, right click ? Copy. And paste in Trusted Root Certification Authority/Certificates.
3. Last step is to select correct bindings in IIS. Go to IIS website, select Bindings, Select SNI checkbox and set the individual certificates for each website.

Make sure website hostname and certificate dns-name should exactly match

Another related tip is to use "%~1" instead of "%1". Type "CALL /?" at the command line in Windows to get more details.

You can achieve almost everything in PROCESS_NUM with this one-liner:

[ `pgrep $1` ] && return 1 || return 0

if you're looking for a partial match, i.e. program is named foobar and you want your $1 to be just foo you can add the -f switch to pgrep:

[[ `pgrep -f $1` ]] && return 1 || return 0

Putting it all together your script could be reworked like this:

#!/bin/bash

check_process() {
  echo "$ts: checking $1"
  [ "$1" = "" ]  && return 0
  [ `pgrep -n $1` ] && return 1 || return 0
}

while [ 1 ]; do 
  # timestamp
  ts=`date +%T`

  echo "$ts: begin checking..."
  check_process "dropbox"
  [ $? -eq 0 ] && echo "$ts: not running, restarting..." && `dropbox start -i > /dev/null`
  sleep 5
done

Running it would look like this:

# SHELL #1
22:07:26: begin checking...
22:07:26: checking dropbox
22:07:31: begin checking...
22:07:31: checking dropbox

# SHELL #2
$ dropbox stop
Dropbox daemon stopped.

# SHELL #1
22:07:36: begin checking...
22:07:36: checking dropbox
22:07:36: not running, restarting...
22:07:42: begin checking...
22:07:42: checking dropbox

Hope this helps!

the default gradle version 3.3 may have some bugs, I switched to gradle 3.5 and everything got ok

Visual Studio 2015: The correct syntax is (keep it on one line):

if "$(ConfigurationName)"=="My Debug CFG" ( xcopy "$(TargetDir)test1.tmp" "$(TargetDir)test.xml" /y) else ( xcopy "$(TargetDir)test2.tmp" "$(TargetDir)test.xml" /y)

No error 255 here.

CREATE TEMPORARY TABLE IF NOT EXISTS to_table_name AS (SELECT * FROM from_table_name)

XAMPP by default uses http://localhost/phpmyadmin

It also requires you start both Apache and MySQL from the control panel (or as a service).

In the XAMPP Control Panel, clicking [ Admin ] on the MySQL line will open your default browser at the configured URL for the phpMyAdmin application.

If you get a phpMyAdmin error stating "Cannot connect: invalid settings." You will need to make sure your MySQL config file has a matching port for server and client. If it is not the standard 3306 port, you will also need to change your phpMyAdmin config file under apache (config.inc.php) to meet the new port settings. (127.0.0.1 becomes 127.0.0.1:<port>)

The right answer (using Python 2.7 and later, since check_output() was introduced then) is:

py2output = subprocess.check_output(['python','py2.py','-i', 'test.txt'])

To demonstrate, here are my two programs:

py2.py:

import sys
print sys.argv

py3.py:

import subprocess
py2output = subprocess.check_output(['python', 'py2.py', '-i', 'test.txt'])
print('py2 said:', py2output)

Running it:

$ python3 py3.py
py2 said: b"['py2.py', '-i', 'test.txt']\n"

Here's what's wrong with each of your versions:

py2output = subprocess.check_output([str('python py2.py '),'-i', 'test.txt'])

First, str('python py2.py') is exactly the same thing as 'python py2.py'—you're taking a str, and calling str to convert it to an str. This makes the code harder to read, longer, and even slower, without adding any benefit.

More seriously, python py2.py can't be a single argument, unless you're actually trying to run a program named, say, /usr/bin/python\ py2.py. Which you're not; you're trying to run, say, /usr/bin/python with first argument py2.py. So, you need to make them separate elements in the list.

Your second version fixes that, but you're missing the ' before test.txt'. This should give you a SyntaxError, probably saying EOL while scanning string literal.

Meanwhile, I'm not sure how you found documentation but couldn't find any examples with arguments. The very first example is:

>>> subprocess.check_output(["echo", "Hello World!"])
b'Hello World!\n'

That calls the "echo" command with an additional argument, "Hello World!".

Also:

-i is a positional argument for argparse, test.txt is what the -i is

I'm pretty sure -i is not a positional argument, but an optional argument. Otherwise, the second half of the sentence makes no sense.

I did that once. Ultimately I found my simplified basicconfig.py adequate for my needs. You can pass in a namespace with other objects for it to reference if you need to. You can also pass in additional defaults from your code. It also maps attribute and mapping style syntax to the same configuration object.

Please follow those steps.

Bundle your js:

if you have index.android.js in project root then run

react-native bundle --dev false --platform android --entry-file index.android.js --bundle-output ./android/app/build/intermediates/assets/debug/index.android.bundle --assets-dest ./android/app/build/intermediates/res/merged/debug

if you have index.js in project root then run

react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res

Create debug apk:

cd android/
./gradlew assembleDebug

Then You can find your apk here:

cd app/build/outputs/apk/

Just enter plt.hold(False) before the first plt.plot, and you can stick to your original code.

The command on OSX should be exactly the same as it is Unix under the pretty UI.

As of Node.js 14.3.0 the top-level await is supported.

Required flag: --experimental-top-level-await.

BufferedReader can't wrap an InputStream directly. It wraps another Reader. In this case you'd want to do something like:

BufferedReader br = new BufferedReader(new InputStreamReader(is, "UTF-8"));

You need to set more fields then just border-width. The style basically puts the border on the page. Width controls the thickness, and color tells it what color to make the border.

border-style: solid; border-width:thin; border-color: #FFFFFF;

Firewalls are often the problem in these situations. Personally, the Mcafee enterprise firewall was causing this issue even for requests within the network.

Disable your firewalls or add a rule for tomcat and see if this helps.

This is not really 'slick' but it's faster to do integer operations than to do string concatenations for each padding 0.

function ZeroPadNumber ( nValue )
{
    if ( nValue < 10 )
    {
        return ( '000' + nValue.toString () );
    }
    else if ( nValue < 100 )
    {
        return ( '00' + nValue.toString () );
    }
    else if ( nValue < 1000 )
    {
        return ( '0' + nValue.toString () );
    }
    else
    {
        return ( nValue );
    }
}

This function is also hardcoded to your particular need (4 digit padding), so it's not generic.

One obvious and straightforward possibility is to use "if-else conditions". In that example

x <- c(1, 2, 4)
y <- c(1, 4, 5)
w <- ifelse(x <= 1, "good", ifelse((x >= 3) & (x <= 5), "bad", "fair"))
data.frame(x, y, w)

** For the additional question in the edit** Is that what you expect ?

> d1 <- c("e", "c", "a")
> d2 <- c("e", "a", "b")
> 
> w <- ifelse((d1 == "e") & (d2 == "e"), 1, 
+    ifelse((d1=="a") & (d2 == "b"), 2,
+    ifelse((d1 == "e"), 3, 99)))
>     
> data.frame(d1, d2, w)
  d1 d2  w
1  e  e  1
2  c  a 99
3  a  b  2

If you do not feel comfortable with the ifelse function, you can also work with the if and else statements for such applications.

Attention: This method saves the credentials in plaintext on your PC's disk. Everyone on your computer can access it, e.g. malicious NPM modules.

Run

git config --global credential.helper store

then

git pull

provide a username and password and those details will then be remembered later. The credentials are stored in a file on the disk, with the disk permissions of "just user readable/writable" but still in plaintext.

If you want to change the password later

git pull

Will fail, because the password is incorrect, git then removes the offending user+password from the ~/.git-credentials file, so now re-run

git pull

to provide a new password so it works as earlier.

Height is missing a p from its value.

Should be height:200*p*x

You can use Apache commons-io for this task:

Refer to this method:

public static byte[] readFileToByteArray(File file) throws IOException

Update:

Java 7 way:

byte[] bytes = Files.readAllBytes(Paths.get(filename));

and if it is a text file and you want to convert it to String (change encoding as needed):

StandardCharsets.UTF_8.decode(ByteBuffer.wrap(bytes)).toString()

This can be done without explicitly using hooks provided you add a prop to your component and a state to the stateless component's parent component:

const ParentComponent = props => {
  const [updateNow, setUpdateNow] = useState(true)

  const updateFunc = () => {
    setUpdateNow(!updateNow)
  }

  const MyComponent = props => {
    return (<div> .... </div>)
  }

  const MyButtonComponent = props => {
    return (<div> <input type="button" onClick={props.updateFunc} />.... </div>)
  }

  return (
    <div> 
      <MyComponent updateMe={updateNow} />
      <MyButtonComponent updateFunc={updateFunc}/>
    </div>
  )
}

You can work it out for yourself given the bucket and the file name you specify in the upload request.

e.g. if your bucket is mybucket and your file is named myfilename:

https://mybucket.s3.amazonaws.com/myfilename

The s3 bit will be different depending on which region your bucket is in. For example, I use the south-east asia region so my urls are like:

https://mybucket.s3-ap-southeast-1.amazonaws.com/myfilename

In DB2, using single quotes instead of your double quotes will work. So that could translate the same in Oracle..

SELECT CustomerName AS Customer, '' AS Contact 
FROM Customers;

If you have Prototype installed, you can tighten up the code to generate and submit the hidden form like this:

 var form = new Element('form',
                        {method: 'post', action: 'http://example.com/'});
 form.insert(new Element('input',
                         {name: 'q', value: 'a', type: 'hidden'}));
 $(document.body).insert(form);
 form.submit();

I found the solution:

public class DefaultPostgresKeyServer
{
    private Session session;
    private Iterator<BigInteger> iter;
    private long batchSize;

    public DefaultPostgresKeyServer (Session sess, long batchFetchSize)
    {
        this.session=sess;
        batchSize = batchFetchSize;
        iter = Collections.<BigInteger>emptyList().iterator();
    }

        @SuppressWarnings("unchecked")
        public Long getNextKey()
        {
            if ( ! iter.hasNext() )
            {
                Query query = session.createSQLQuery( "SELECT nextval( 'mySchema.mySequence' ) FROM generate_series( 1, " + batchSize + " )" );

                iter = (Iterator<BigInteger>) query.list().iterator();
            }
            return iter.next().longValue() ;
        }

}

With jQuery (and without FormData API) you can use something like this:

function readFile(file){
   var loader = new FileReader();
   var def = $.Deferred(), promise = def.promise();

   //--- provide classic deferred interface
   loader.onload = function (e) { def.resolve(e.target.result); };
   loader.onprogress = loader.onloadstart = function (e) { def.notify(e); };
   loader.onerror = loader.onabort = function (e) { def.reject(e); };
   promise.abort = function () { return loader.abort.apply(loader, arguments); };

   loader.readAsBinaryString(file);

   return promise;
}

function upload(url, data){
    var def = $.Deferred(), promise = def.promise();
    var mul = buildMultipart(data);
    var req = $.ajax({
        url: url,
        data: mul.data,
        processData: false,
        type: "post",
        async: true,
        contentType: "multipart/form-data; boundary="+mul.bound,
        xhr: function() {
            var xhr = jQuery.ajaxSettings.xhr();
            if (xhr.upload) {

                xhr.upload.addEventListener('progress', function(event) {
                    var percent = 0;
                    var position = event.loaded || event.position; /*event.position is deprecated*/
                    var total = event.total;
                    if (event.lengthComputable) {
                        percent = Math.ceil(position / total * 100);
                        def.notify(percent);
                    }                    
                }, false);
            }
            return xhr;
        }
    });
    req.done(function(){ def.resolve.apply(def, arguments); })
       .fail(function(){ def.reject.apply(def, arguments); });

    promise.abort = function(){ return req.abort.apply(req, arguments); }

    return promise;
}

var buildMultipart = function(data){
    var key, crunks = [], bound = false;
    while (!bound) {
        bound = $.md5 ? $.md5(new Date().valueOf()) : (new Date().valueOf());
        for (key in data) if (~data[key].indexOf(bound)) { bound = false; continue; }
    }

    for (var key = 0, l = data.length; key < l; key++){
        if (typeof(data[key].value) !== "string") {
            crunks.push("--"+bound+"\r\n"+
                "Content-Disposition: form-data; name=\""+data[key].name+"\"; filename=\""+data[key].value[1]+"\"\r\n"+
                "Content-Type: application/octet-stream\r\n"+
                "Content-Transfer-Encoding: binary\r\n\r\n"+
                data[key].value[0]);
        }else{
            crunks.push("--"+bound+"\r\n"+
                "Content-Disposition: form-data; name=\""+data[key].name+"\"\r\n\r\n"+
                data[key].value);
        }
    }

    return {
        bound: bound,
        data: crunks.join("\r\n")+"\r\n--"+bound+"--"
    };
};

//----------
//---------- On submit form:
var form = $("form");
var $file = form.find("#file");
readFile($file[0].files[0]).done(function(fileData){
   var formData = form.find(":input:not('#file')").serializeArray();
   formData.file = [fileData, $file[0].files[0].name];
   upload(form.attr("action"), formData).done(function(){ alert("successfully uploaded!"); });
});

With FormData API you just have to add all fields of your form to FormData object and send it via $.ajax({ url: url, data: formData, processData: false, contentType: false, type:"POST"})

find . -type d | while read file; do echo $file; done

However, doesn't work if the file-name contains newlines. The above is the only solution i know of when you actually want to have the directory name in a variable. If you just want to execute some command, use xargs.

find . -type d -print0 | xargs -0 echo 'The directory is: '

You can use a ternary operator

echo false ? 'true' : 'false';

amap.find returns amap::end when it does not find what you're looking for -- you're supposed to check for that.

This works well for specific articles where the text is all wrapped in <p> tags. Since the web is an ugly place, it's not always the case.

Often, websites will have text scattered all over, wrapped in different types of tags (e.g. maybe in a <span> or a <div>, or an <li>).

To find all text nodes in the DOM, you can use soup.find_all(text=True).

This is going to return some undesired text, like the contents of <script> and <style> tags. You'll need to filter out the text contents of elements you don't want.

blacklist = [
  'style',
  'script',
  # other elements,
]

text_elements = [t for t in soup.find_all(text=True) if t.parent.name not in blacklist]

If you are working with a known set of tags, you can tag the opposite approach:

whitelist = [
  'p'
]

text_elements = [t for t in soup.find_all(text=True) if t.parent.name in whitelist]

$request->attributes->get('_route');

You can get the route name from the request object from within the controller.

Use ShellJS module.

exec function without providing callback.

Example:

var version = exec('node -v').output;

Try setting host=127.0.0.1 on your db settings file, it worked for me! :)

Hope it helps!

$ids = sprintf("'%s'", implode("','", $ids ) );

Use:

list.removeAll(...);
//post what char you need in the ... section

Try this:

Write-Host ($obj | Format-Table | Out-String)

or

Write-Host ($obj | Format-List | Out-String)

The following shows an example of a shared class library shared.[h,cpp] and a main.cpp module using the library. It's a very simple example and the makefile could be made much better. But it works and may help you:

shared.h defines the class:

class myclass {
   int myx;

  public:

    myclass() { myx=0; }
    void setx(int newx);
    int  getx();
};

shared.cpp defines the getx/setx functions:

#include "shared.h"

void myclass::setx(int newx) { myx = newx; }
int  myclass::getx() { return myx; }

main.cpp uses the class,

#include <iostream>
#include "shared.h"

using namespace std;

int main(int argc, char *argv[])
{
  myclass m;

  cout << m.getx() << endl;
  m.setx(10);
  cout << m.getx() << endl;
}

and the makefile that generates libshared.so and links main with the shared library:

main: libshared.so main.o
    $(CXX) -o main  main.o -L. -lshared

libshared.so: shared.cpp
    $(CXX) -fPIC -c shared.cpp -o shared.o
    $(CXX) -shared  -Wl,-soname,libshared.so -o libshared.so shared.o

clean:
    $rm *.o *.so

To actual run 'main' and link with libshared.so you will probably need to specify the load path (or put it in /usr/local/lib or similar).

The following specifies the current directory as the search path for libraries and runs main (bash syntax):

export LD_LIBRARY_PATH=.
./main

To see that the program is linked with libshared.so you can try ldd:

LD_LIBRARY_PATH=. ldd main

Prints on my machine:

  ~/prj/test/shared$ LD_LIBRARY_PATH=. ldd main
    linux-gate.so.1 =>  (0xb7f88000)
    libshared.so => ./libshared.so (0xb7f85000)
    libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb7e74000)
    libm.so.6 => /lib/libm.so.6 (0xb7e4e000)
    libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0xb7e41000)
    libc.so.6 => /lib/libc.so.6 (0xb7cfa000)
    /lib/ld-linux.so.2 (0xb7f89000)

Be careful that don't use [email protected] or [email protected] with [email protected]. URL will update after history.push or any other push to history instructions but navigation is not working with react-router. use npm install [email protected] to change the history version. see React router not working after upgrading to v 5.

I think this problem is happening when push to history happened. for example using <NavLink to="/apps"> facing a problem in NavLink.js that consume <RouterContext.Consumer>. context.location is changing to an object with action and location properties when the push to history occurs. So currentLocation.pathname is null to match the path.

Swift 4 Examples

Example #1 using closure

NotificationCenter.default.addObserver(forName: .UIApplicationUserDidTakeScreenshot, 
                                       object: nil, 
                                       queue: OperationQueue.main) { notification in
    print("\(notification) that a screenshot was taken!")
}

Example #2 with selector

NotificationCenter.default.addObserver(self, 
                                       selector: #selector(screenshotTaken), 
                                       name: .UIApplicationUserDidTakeScreenshot, 
                                       object: nil)

@objc func screenshotTaken() {
    print("Screenshot taken!")
}

<div style="cursor:pointer;" onclick="document.location='http://www.google.com'">Foo</div>

The first 2 examples act very differently if you are REPLACING them by something. If you match on this:

str = str.replace(/^(7|8|9)/ig,''); 

you would replace 7 or 8 or 9 by the empty string.

If you match on this

str = str.replace(/^[7|8|9]/ig,''); 

you will replace 7 or 8 or 9 OR THE VERTICAL BAR!!!! by the empty string.

I just found this out the hard way.

A couple of additional points re use of vector here.

Unlike ArrayList and Array in Java, you don't need to do anything special to treat a vector as an array - the underlying storage in C++ is guaranteed to be contiguous and efficiently indexable.

Unlike ArrayList, a vector can efficiently hold primitive types without encapsulation as a full-fledged object.

When removing items from a vector, be aware that the items above the removed item have to be moved down to preserve contiguous storage. This can get expensive for large containers.

Make sure if you store complex objects in the vector that their copy constructor and assignment operators are efficient. Under the covers, C++ STL uses these during container housekeeping.

Advice about reserve()ing storage upfront (ie. at vector construction or initialilzation time) to minimize memory reallocation on later extension carries over from Java to C++.

exec sp_msforeachtable 'print ''?'''

If all other methods are not working for you... Try

npm link package_name

e.g

npm link webpack
npm link autoprefixer

e.t.c

In your SQL Developer Bin Folder find

\sqldeveloper\bin\sqldeveloper.conf

It should be

SetJavaHome \path\to\jdk

You said it was ../../jdk originally so you could ultimatey do 1 of two things:

SetJavaHome C:\Program Files\Java\jdk1.7.0_60

This is assuming that you have JDK 1.7.60 installed in that directory; you don't want to point it to the bin folder you want the whole JDK folder.

OR

The second thing you can do is find the jdk folder in the sqldeveloper folder for me its sqldeveloper\jdk and copy and paste the contents from C:\Program Files\Java\jdk1.7.0_60. You then have to revert your change to read

SetJavaHome ../../jdk

in your sqldeveloper.conf

If all else fails you can always redownload the sqldeveloper that already contains the jdk7 all zipped up and ready for you to run at will: Download SQL Developer The file I talk about is called Windows 64-bit - zip file includes the JDK 7

Or you might have something like this (redeclaring a variable):

var data = [];
var data = 

In the converter of the chosen solution, you should add values.Clone() otherwise the parameters in the command end null

public class YourConverter : IMultiValueConverter
{
    public object Convert(object[] values, ...)
    {
        return values.Clone();
    }

    ...
}

The solution you want is the one proposed here:

https://stackoverflow.com/a/542802/50776

Basically, you do this:

cast(floor(cast(@dateVariable as float)) as datetime)

There is a function definition in the link which will allow you to consolidate the functionality and call it anywhere (instead of having to remember it) if you wish.

its a matter of speed. using the iterator accesses the elements faster. a similar question was answered here:

What's faster, iterating an STL vector with vector::iterator or with at()?

Edit: speed of access varies with each cpu and compiler

Don't need to Break head with setState() in react.js

A new library made by me React-chopper

Code Like angularjs in reactjs

Code without setState in reactjs

Go through examples for more description

import React, { Component } from 'react';
import { render } from 'react-dom';
import Rcp from 'react-chopper';

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      name: 'React'
    };
    this.modal = Rcp(this.state, this);
  }

  tank = () => {
    console.log(this.modal)
  }
  render() {
    return (
      <div>
        <input value={this.modal.name} onChange={e => this.modal.name = e.target.value} />
        <p> Bang Bang {this.modal.name} </p>

Share Files, Folders or Drives Between Host and Hyper-V Virtual Machine

Prerequisites

1. Ensure that Enhanced session mode settings are enabled on the Hyper-V host.

   Start Hyper-V Manager, and in the Actions section, select "Hyper-V Settings".

   

   Make sure that enhanced session mode is allowed in the Server section. Then, make sure that the enhanced session mode is available in the User section.

   

2. Enable Hyper-V Guest Services for your virtual machine

   Right-click on Virtual Machine > Settings. Select the Integration Services in the left-lower corner of the menu. Check Guest Service and click OK.

   

Steps to share devices with Hyper-v virtual machine:

1. Start a virtual machine and click Show Options in the pop-up windows.

   

   Or click "Edit Session Settings..." in the Actions panel on the right

   

   It may only appear when you're (able to get) connected to it. If it doesn't appear try Starting and then Connecting to the VM while paying close attention to the panel in the Hyper-V Manager.

2. View local resources. Then, select the "More..." menu.

   

3. From there, you can choose which devices to share. Removable drives are especially useful for file sharing.

   

4. Choose to "Save my settings for future connections to this virtual machine".

   

5. Click Connect. Drive sharing is now complete, and you will see the shared drive in this PC > Network Locations section of Windows Explorer after using the enhanced session mode to sigh to the VM. You should now be able to copy files from a physical machine and paste them into a virtual machine, and vice versa.

Update: AdoptOpenJDK has changed its name to Adoptium, as part of its move to the Eclipse Foundation.

OpenJDK ? source code
Adoptium/AdoptOpenJDK ? builds

Difference between OpenJDK and AdoptOpenJDK

The first provides source-code, the other provides builds of that source-code.

• OpenJDK is an open-source project providing source-code (not builds) of an implementation of the Java platform as defined by:
  • the Java Specifications
  • Java Specification Request (JSR) documents published by Oracle via the Java Community Process
  • JDK Enhancement Proposal (JEP) documents published by Oracle via the OpenJDK project
• AdoptOpenJDK is an organization founded by some prominent members of the Java community aimed at providing binary builds and installers at no cost for users of Java technology.

Several vendors of Java & OpenJDK

Adoptium of the Eclipse Foundation, formerly known as AdoptOpenJDK, is only one of several vendors distributing implementations of the Java platform. These include:

• Eclipse Foundation (Adoptium/AdoptOpenJDK)
• Azul Systems
• Oracle
• Red Hat / IBM
• BellSoft
• SAP
• Amazon AWS
• … and more

See this flowchart of mine to help guide you in picking a vendor for an implementation of the Java platform. Click/tap to zoom.

Another resource: This comparison matrix by Azul Systems is useful, and seems true and fair to my mind.

Here is a list of considerations and motivations to consider in choosing a vendor and implementation.

Some vendors offer you a choice of JIT technologies.

If you're trying to take advantage of polymorphic behavior, you need to ensure that the methods visible to outside classes (that need polymorphism) have the same signature. That means they need to have the same name, number and order of parameters, as well as the parameter types.

In your case, you might do better to have a generic draw() method, and rely on the subclasses (Rectangle, Ellipse) to implement the draw() method as what you had been thinking of as "drawEllipse" and "drawRectangle".

This happened to me on a old simple project without branches. I made a lot of changes and when I was done, I couldn't commit. Nothing above worked so I ended up with:

1. Copied all the code with my latest changes to a Backup-folder.
2. Git clone to download the latest working code along with the working .git folder.
3. Copied my code with latest changes from the backup and replaced the cloned code (not the .git folder).
4. git add and commit works again and I have all my recent changes.

Error checking and handling is the programmer's friend. Check the return values of the initializing and executing cURL functions. curl_error() and curl_errno() will contain further information in case of failure:

try {
    $ch = curl_init();

    // Check if initialization had gone wrong*    
    if ($ch === false) {
        throw new Exception('failed to initialize');
    }

    curl_setopt($ch, CURLOPT_URL, 'http://example.com/');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt(/* ... */);

    $content = curl_exec($ch);

    // Check the return value of curl_exec(), too
    if ($content === false) {
        throw new Exception(curl_error($ch), curl_errno($ch));
    }

    /* Process $content here */

    // Close curl handle
    curl_close($ch);
} catch(Exception $e) {

    trigger_error(sprintf(
        'Curl failed with error #%d: %s',
        $e->getCode(), $e->getMessage()),
        E_USER_ERROR);

}

^* The curl_init() manual states:

Returns a cURL handle on success, FALSE on errors.

I've observed the function to return FALSE when you're using its $url parameter and the domain could not be resolved. If the parameter is unused, the function might never return FALSE. Always check it anyways, though, since the manual doesn't clearly state what "errors" actually are.

One way would be to make a list of lists, with each sub-list in the new list containing a word and a count:

list1 = []    #this is your original list of words
list2 = []    #this is a new list

for word in list1:
    if word in list2:
        list2.index(word)[1] += 1
    else:
        list2.append([word,0])

Or, more efficiently:

for word in list1:
    try:
        list2.index(word)[1] += 1
    except:
        list2.append([word,0])

This would be less efficient than using a dictionary, but it uses more basic concepts.

try this:

var count_element = $('.element').length

Another convoluted answer which should technically work and is ok for a small number of data points is to plot all your data points as 1 series in order to get your connecting line. Then plot each point as its own series. Then format data labels to display series name for each of the individual data points.

In short it works ok for a small data set or just key points from a data set.
