Programs & Examples On #Netnamedpipebinding

In Swift 5.1 this will work:

var counter = 30

override func viewDidLoad() {
    super.viewDidLoad()

    Timer.scheduledTimer(timeInterval: 1.0, target: self, selector: #selector(updateCounter), userInfo: nil, repeats: true)
}



@objc func updateCounter() {
    //example functionality
    if counter > 0 {
        print("\(counter) seconds to the end of the world")
        counter -= 1
    }
}

I came across this error message through a silly mistake. A classic example of Python giving you plenty of room to make a fool of yourself. Observe:

class DOH(object):
def __init__(self, property=None):
    self.property=property

def property():
    return property

x = DOH(1)
print(x.property())

Results

$ python3 t.py
Traceback (most recent call last):
  File "t.py", line 9, in <module>
    print(x.property())
TypeError: 'int' object is not callable

The problem here of course is that the function is overwritten with a property.

In Eclipse from your project:

1. Right-click on your project
2. Click Properties
3. Java build path: Libraries; Remove the "JRE System Library[J2SE 1.4]"
4. Click Add Library -> JRE System Library
5. Select the new "Execution Environment" or Workspace default JRE

This only works after you save a bookmark to the app to the home screen. Not if you just browse to the site normally.

From what I saw in Express 4.0 this works for me. This is example of authentication required middleware.

function apiDemandLoggedIn(req, res, next) {

    // if user is authenticated in the session, carry on
    console.log('isAuth', req.isAuthenticated(), req.user);
    if (req.isAuthenticated())
        return next();

    // If not return 401 response which means unauthroized.
    var err = new Error();
    err.status = 401;
    next(err);
}

Besides using std::find (from algorithm), you can also use std::find_if (which is, IMO, better than std::find), or other find algorithm from this list

#include <list>
#include <algorithm>
#include <iostream>

int main()
{
    std::list<int> myList{ 5, 19, 34, 3, 33 };
    

    auto it = std::find_if( std::begin( myList ),
                            std::end( myList ),
                            [&]( const int v ){ return 0 == ( v % 17 ); } );
        
    if ( myList.end() == it )
    {
        std::cout << "item not found" << std::endl;
    }
    else
    {
        const int pos = std::distance( myList.begin(), it ) + 1;
        std::cout << "item divisible by 17 found at position " << pos << std::endl;
    }
}

You can also use the following construct:

String[][] myStringArray = new String [][] { { "X0", "Y0"},
                                             { "X1", "Y1"},
                                             { "X2", "Y2"},
                                             { "X3", "Y3"},
                                             { "X4", "Y4"} };

ssh -t 'command; bash -l'

will execute the command and then start up a login shell when it completes. For example:

ssh -t [email protected] 'cd /some/path; bash -l'

It's a buzzword that refers to things like the normal Web architecture with e.g., Javascript - ASP.Net - Middleware - Database layer. Each of these things is a "tier".

tl;dr: use OSX's native process launcher and manager, launchd.

To do so, make a launchctl daemon. You'll have full control over all aspects of the script. You can run once or keep alive as a daemon. In most cases, this is the way to go.

1. Create a .plist file according to the instructions in the Apple Dev docs here or more detail below.
2. Place in ~/Library/LaunchAgents
3. Log in (or run manually via launchctl load [filename.plist])

For more on launchd, the wikipedia article is quite good and describes the system and its advantages over other older systems.

Here's the specific plist file to run a script at login.

Updated 2017/09/25 for OSX El Capitan and newer (credit to José Messias Jr):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
   <key>Label</key>
   <string>com.user.loginscript</string>
   <key>ProgramArguments</key>
   <array><string>/path/to/executable/script.sh</string></array>
   <key>RunAtLoad</key>
   <true/>
</dict>
</plist>

Replace the <string> after the Program key with your desired command (note that any script referenced by that command must be executable: chmod a+x /path/to/executable/script.sh to ensure it is for all users).

Save as ~/Library/LaunchAgents/com.user.loginscript.plist

Run launchctl load ~/Library/LaunchAgents/com.user.loginscript.plist and log out/in to test (or to test directly, run launchctl start com.user.loginscript)

Tail /var/log/system.log for error messages.

The key is that this is a User-specific launchd entry, so it will be run on login for the given user. System-specific launch daemons (placed in /Library/LaunchDaemons) are run on boot.

If you want a script to run on login for all users, I believe LoginHook is your only option, and that's probably the reason it exists.

It might help somebody.

I had the similar error message, but only in dev and staging environments, not in production. The valid redirect URIs were correctly set, for the dev and staging subdomains as well as for production.

It turned out I forgot that for those environments we use the testing FB app, which is a separate one in the FB developer page. Had to select that and update its settings.

This is finally what did it for me (and triggers a disposition):

function onClick() {_x000D_
  var pdf = new jsPDF('p', 'pt', 'letter');_x000D_
  pdf.canvas.height = 72 * 11;_x000D_
  pdf.canvas.width = 72 * 8.5;_x000D_
_x000D_
  pdf.fromHTML(document.body);_x000D_
_x000D_
  pdf.save('test.pdf');_x000D_
};_x000D_
_x000D_
var element = document.getElementById("clickbind");_x000D_
element.addEventListener("click", onClick);

<h1>Dsdas</h1>_x000D_
_x000D_
<a id="clickbind" href="#">Click</a>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.3/jspdf.min.js"></script>

And for those of the KnockoutJS inclination, a little binding:

ko.bindingHandlers.generatePDF = {
    init: function(element) {

        function onClick() {
            var pdf = new jsPDF('p', 'pt', 'letter');
            pdf.canvas.height = 72 * 11;
            pdf.canvas.width = 72 * 8.5;

            pdf.fromHTML(document.body);

            pdf.save('test.pdf');                    
        };

        element.addEventListener("click", onClick);
    }
};

Try installing gradle and include it into your path. Click the link below to get manual. https://gradle.org/install

Note that the aspx and ascx solutions require a current HttpContext, so cannot be used asynchronously (eg in threads) without a lot of work.

This is the answer to make this work for Java 11 and above since the entire JAXB APIs were removed.

Download Jakarta XML Binding, specifically this zip file. You need only the 3 files within mod folder i.e. jakarta.activation.jar, jakarta.xml.bind-api.jar and jakarta.xml.bind-api.jar and you can toss the rest off.

Move these files to APP_HOME/lib folder. I created a sub folder jaxb inside for this. So, on my macOS system this was: $HOME/Library/Android/sdk/tools/lib/jaxb

Now open sdkmanager using your favorite text editor and under CLASSPATH= add the following at th beginning:

$APP_HOME/lib/jaxb/jakarta.activation.jar:$APP_HOME/lib/jaxb/jakarta.xml.bind-api.jar:$APP_HOME/lib/jaxb/jaxb-impl.jar

So it ended up looking like:

CLASSPATH=$APP_HOME/lib/jaxb/jakarta.activation.jar:$APP_HOME/lib/jaxb/jakarta.xml.bind-api.jar:$APP_HOME/lib/jaxb/jaxb-impl.jar:$APP_HOME/lib/dvlib-26.0.0-dev.jar:$APP_HOME/lib/jimfs-1.1.jar:$APP_HOME/lib/jsr305-1.3.9.jar:$APP_HOME/lib/repository-26.0.0-dev.jar:$APP_HOME/lib/j2objc-annotations-1.1.jar:$APP_HOME/lib/layoutlib-api-26.0.0-dev.jar:$APP_HOME/lib/gson-2.3.jar:$APP_HOME/lib/httpcore-4.2.5.jar:$APP_HOME/lib/commons-logging-1.1.1.jar:$APP_HOME/lib/commons-compress-1.12.jar:$APP_HOME/lib/annotations-26.0.0-dev.jar:$APP_HOME/lib/error_prone_annotations-2.0.18.jar:$APP_HOME/lib/animal-sniffer-annotations-1.14.jar:$APP_HOME/lib/httpclient-4.2.6.jar:$APP_HOME/lib/commons-codec-1.6.jar:$APP_HOME/lib/common-26.0.0-dev.jar:$APP_HOME/lib/kxml2-2.3.0.jar:$APP_HOME/lib/httpmime-4.1.jar:$APP_HOME/lib/annotations-12.0.jar:$APP_HOME/lib/sdklib-26.0.0-dev.jar:$APP_HOME/lib/guava-22.0.jar

And that's pretty much it, should solve the issue.

I did these steps because flutter doctor --android-licenses was giving me issues. And this fixed it.

 jquery.ajax({
            url: `//your api url`
            type: "GET",
            dataType: "json",
            success: function(data) {
                jQuery.each(data, function(index, value) {
                        console.log(data);
                        `All you API data is here`
                    }
                }
            });     

I like @AJP's answer. I used it verbatim until I ended up with a lot of functions. Then I switched to a Python function decorator.

from jinja2 import Template

template = '''
Hi, my name is {{ custom_function1(first_name) }}
My name is {{ custom_function2(first_name) }}
My name is {{ custom_function3(first_name) }}
'''
jinga_html_template = Template(template)

def template_function(func):
    jinga_html_template.globals[func.__name__] = func
    return func

@template_function
def custom_function1(a):
    return a.replace('o', 'ay')

@template_function
def custom_function2(a):
    return a.replace('o', 'ill')

@template_function
def custom_function3(a):
    return 'Slim Shady'

fields = {'first_name': 'Jo'}
print(jinga_html_template.render(**fields))

Good thing functions have a __name__!

Here a little ES6 function if somebody wants to use it in React for example

Also don't forget the obvious, does the data in the tables need to have case? You could only insert rows already in lower case (or convert the existing DB rows to lower case) and be done with it right from the start.

Here is a way to translate the whole tree into a single (not necessarily too human-readable) python expression using the SKompiler library:

from skompiler import skompile
skompile(dtree.predict).to('python/code')

In your case, the first value to insert must be NULL, because it's AUTO_INCREMENT.

Assuming that your original dataset is similar to the one you created (i.e. with NA as character. You could specify na.strings while reading the data using read.table. But, I guess NAs would be detected automatically.

The price column is factor which needs to be converted to numeric class. When you use as.numeric, all the non-numeric elements (i.e. "NA", FALSE) gets coerced to NA) with a warning.

library(dplyr)
df %>%
     mutate(price=as.numeric(as.character(price))) %>%  
     group_by(company, year, product) %>%
     summarise(total.count=n(), 
               count=sum(is.na(price)), 
               avg.price=mean(price,na.rm=TRUE),
               max.price=max(price, na.rm=TRUE))

data

I am using the same dataset (except the ... row) that was showed.

df = tbl_df(data.frame(company=c("Acme", "Meca", "Emca", "Acme", "Meca","Emca"),
 year=c("2011", "2010", "2009", "2011", "2010", "2013"), product=c("Wrench", "Hammer",
 "Sonic Screwdriver", "Fairy Dust", "Kindness", "Helping Hand"), price=c("5.67",
 "7.12", "12.99", "10.99", "NA",FALSE)))

To improve the effectiveness of class='ng-cloak' approach when scripts are loaded last, make sure the following css is loaded in the head of the document:

.ng-cloak { display:none; }

This might be just a requirement of PyMySql in Python, but I found that I had to name the exact table that I wanted the ID for:

In:

cnx = pymysql.connect(host='host',
                            database='db',
                            user='user',
                            password='pass')
cursor = cnx.cursor()
update_batch = """insert into batch set type = "%s" , records = %i, started = NOW(); """
second_query = (update_batch % ( "Batch 1", 22  ))
cursor.execute(second_query)
cnx.commit()
batch_id = cursor.execute('select last_insert_id() from batch')
cursor.close()

batch_id

Out: 5
... or whatever the correct Batch_ID value actually is

All standard implementations of java.util.List already implement java.io.Serializable.

So even though java.util.List itself is not a subtype of java.io.Serializable, it should be safe to cast the list to Serializable, as long as you know it's one of the standard implementations like ArrayList or LinkedList.

If you're not sure, then copy the list first (using something like new ArrayList(myList)), then you know it's serializable.

If your DBMS doesn't support distinct with multiple columns like this:

select distinct(col1, col2) from table

Multi select in general can be executed safely as follows:

select distinct * from (select col1, col2 from table ) as x

As this can work on most of the DBMS and this is expected to be faster than group by solution as you are avoiding the grouping functionality.

In some cases first your need to Release, then Remove and Re-add via Virtual Media Manager

You need to ensure that any code that modifies the HTTP headers is executed before the headers are sent. This includes statements like session_start(). The headers will be sent automatically when any HTML is output.

Your problem here is that you're sending the HTML ouput at the top of your page before you've executed any PHP at all.

Move the session_start() to the top of your document :

<?php    session_start(); ?> <html> <head> <title>PHP SDK</title> </head> <body> <?php require_once 'src/facebook.php';    // more PHP code here. 

Your code can be narrowed down to

Sub DeleteTableRows(ByRef Table As ListObject)
    On Error Resume Next
    '~~> Clear Header Row `IF` it exists
    Table.DataBodyRange.Rows(1).ClearContents
    '~~> Delete all the other rows `IF `they exist
    Table.DataBodyRange.Offset(1, 0).Resize(Table.DataBodyRange.Rows.Count - 1, _
    Table.DataBodyRange.Columns.Count).Rows.Delete
    On Error GoTo 0
End Sub

Edit:

On a side note, I would add proper error handling if I need to intimate the user whether the first row or the other rows were deleted or not

You can try this. Function below sets all values of object's properties to undefined. Works as well with nested objects.

var clearObjectValues = (objToClear) => {
    Object.keys(objToClear).forEach((param) => {
        if ( (objToClear[param]).toString() === "[object Object]" ) {
            clearObjectValues(objToClear[param]);
        } else {
            objToClear[param] = undefined;
        }
    })
    return objToClear;
};

try this one

SELECT COUNT(id)
FROM stats
GROUP BY EXTRACT(YEAR_MONTH FROM record_date)

EXTRACT(unit FROM date) function is better as less grouping is used and the function return a number value.

Comparison condition when grouping will be faster than DATE_FORMAT function (which return a string value). Try using function|field that return non-string value for SQL comparison condition (WHERE, HAVING, ORDER BY, GROUP BY).

You need to give a function to be called after the time delay as the second argument to after:

after(delay_ms, callback=None, *args)

Registers an alarm callback that is called after a given time.

So what you really want to do is this:

tiles_letter = ['a', 'b', 'c', 'd', 'e']

def add_letter():
    rand = random.choice(tiles_letter)
    tile_frame = Label(frame, text=rand)
    tile_frame.pack()
    root.after(500, add_letter)
    tiles_letter.remove(rand)  # remove that tile from list of tiles


root.after(0, add_letter)  # add_letter will run as soon as the mainloop starts.
root.mainloop()

You also need to schedule the function to be called again by repeating the call to after inside the callback function, since after only executes the given function once. This is also noted in the documentation:

The callback is only called once for each call to this method. To keep calling the callback, you need to reregister the callback inside itself

Note that your example will throw an exception as soon as you've exhausted all the entries in tiles_letter, so you need to change your logic to handle that case whichever way you want. The simplest thing would be to add a check at the beginning of add_letter to make sure the list isn't empty, and just return if it is:

def add_letter():
    if not tiles_letter:
        return
    rand = random.choice(tiles_letter)
    tile_frame = Label(frame, text=rand)
    tile_frame.pack()
    root.after(500, add_letter)
    tiles_letter.remove(rand)  # remove that tile from list of tiles

Live-Demo: repl.it

I think when you define a function with "var foo = function() {...};", the function is only defined after that line. In other words, try this:

var replaceHtmlEntites = (function() {
  var translate_re = /&(nbsp|amp|quot|lt|gt);/g;
  var translate = {
    "nbsp": " ",
    "amp" : "&",
    "quot": "\"",
    "lt"  : "<",
    "gt"  : ">"
  };
  return function(s) {
    return ( s.replace(translate_re, function(match, entity) {
      return translate[entity];
    }) );
  }
})();

var cleanText = text.replace(/^\xa0*([^\xa0]*)\xa0*$/g,"");
cleanText = replaceHtmlEntities(text);

Edit: Also, only use "var" the first time you declare a variable (you're using it twice on the cleanText variable).

Edit 2: The problem is the spelling of the function name. You have "var replaceHtmlEntites =". It should be "var replaceHtmlEntities ="

Someone should mark Johannes Weiß's comment as the answer to this question. That is exactly why xml documents can't just be loaded in a DOM Document class.

http://en.wikipedia.org/wiki/Byte_order_mark

This will work.

def check(arr):
    if np.all(arr == 0):
        return True
    return False

Here is the complete code

#include <bits/stdc++.h>

using namespace std;

typedef unsigned char BYTE;

int main() {
  //method 1;
  std::vector<BYTE> data = {'H','E','L','L','O','1','2','3'};
  //string constructor accepts only const char
  std::string s((const char*)&(data[0]), data.size());
  std::cout << s << std::endl;

  //method 2
  std::string s2(data.begin(),data.end());
  std::cout << s2 << std::endl;

  //method 3
  std::string s3(reinterpret_cast<char const*>(&data[0]), data.size()) ;
  std::cout << s3 << std::endl;
 
  return 0;
}

An easy, loop-free alternative is to use the horizontalalignment Text property as a keyword argument to xticks[1]. In the below, at the commented line, I've forced the xticks alignment to be "right".

n=5
x = np.arange(n)
y = np.sin(np.linspace(-3,3,n))
xlabels = ['Long ticklabel %i' % i for i in range(n)]
fig, ax = plt.subplots()
ax.plot(x,y, 'o-')

plt.xticks(
        [0,1,2,3,4],
        ["this label extends way past the figure's left boundary",
        "bad motorfinger", "green", "in the age of octopus diplomacy", "x"], 
        rotation=45,
        horizontalalignment="right")    # here
plt.show()

(yticks already aligns the right edge with the tick by default, but for xticks the default appears to be "center".)

[1] You find that described in the xticks documentation if you search for the phrase "Text properties".

If you want more control, you might want to check the TextPaint class. Here is how to use it:

final ClickableSpan clickableSpan = new ClickableSpan() {
    @Override
    public void onClick(final View textView) {
        //Your onClick code here
    }

    @Override
    public void updateDrawState(final TextPaint textPaint) {
        textPaint.setColor(yourContext.getResources().getColor(R.color.orange));
        textPaint.setUnderlineText(true);
    }
};

Had the same issue, In my case I had 1. Parse the string into Json 2. Ensure that when I render my view does not try to display the whole object, but object.value

data = [
{
    "id": 1,
    "name": "Home Page",
    "info": "This little bit of info is being loaded from a Rails 
    API.",
    "created_at": "2018-09-18T16:39:22.184Z",
    "updated_at": "2018-09-18T16:39:22.184Z"
}];
var jsonData = JSON.parse(data)

Then my view

return (
<View style={styles.container}>
  <FlatList
    data={jsonData}
    renderItem={({ item }) => <Item title={item.name} />}
    keyExtractor={item => item.id}
  />
</View>);

Because I'm using an array, I used flat list to display, and ensured I work with object.value, not object otherwise you'll get the same issue

The proper way of using NSLog, as the warning tries to explain, is the use of a formatter, instead of passing in a literal:

Instead of:

NSString *digit = [[sender titlelabel] text];
NSLog(digit);

Use:

NSString *digit = [[sender titlelabel] text];
NSLog(@"%@",digit);

It will still work doing that first way, but doing it this way will get rid of the warning.

Anjuta has a built in SVN plugin which is integrated with the IDE.

Following is the code snippet which shows better way to handle the response body as a String whether it's a valid response or error response for the HTTP POST request:

BufferedReader reader = null;
OutputStream os = null;
String payload = "";
try {
    URL url1 = new URL("YOUR_URL");
    HttpURLConnection postConnection = (HttpURLConnection) url1.openConnection();
    postConnection.setRequestMethod("POST");
    postConnection.setRequestProperty("Content-Type", "application/json");
    postConnection.setDoOutput(true);
    os = postConnection.getOutputStream();
    os.write(eventContext.getMessage().getPayloadAsString().getBytes());
    os.flush();

    String line;
    try{
        reader = new BufferedReader(new InputStreamReader(postConnection.getInputStream()));
    }
    catch(IOException e){
        if(reader == null)
            reader = new BufferedReader(new InputStreamReader(postConnection.getErrorStream()));
    }
    while ((line = reader.readLine()) != null)
        payload += line.toString();
}       
catch (Exception ex) {
            log.error("Post request Failed with message: " + ex.getMessage(), ex);
} finally {
    try {
        reader.close();
        os.close();
    } catch (IOException e) {
        log.error(e.getMessage(), e);
        return null;
    }
}

You can use bootstrap flex class name like that:

<div class="d-flex justify-content-center">
    // the elements you want to center
</div>

That will work even with number of elements inside.

Use os.path.isfile() with os.access():

import os

PATH = './file.txt'
if os.path.isfile(PATH) and os.access(PATH, os.R_OK):
    print("File exists and is readable")
else:
    print("Either the file is missing or not readable")

Let's say you want to scale a range [min,max] to [a,b]. You're looking for a (continuous) function that satisfies

f(min) = a
f(max) = b

In your case, a would be 1 and b would be 30, but let's start with something simpler and try to map [min,max] into the range [0,1].

Putting min into a function and getting out 0 could be accomplished with

f(x) = x - min   ===>   f(min) = min - min = 0

So that's almost what we want. But putting in max would give us max - min when we actually want 1. So we'll have to scale it:

        x - min                                  max - min
f(x) = ---------   ===>   f(min) = 0;  f(max) =  --------- = 1
       max - min                                 max - min

which is what we want. So we need to do a translation and a scaling. Now if instead we want to get arbitrary values of a and b, we need something a little more complicated:

       (b-a)(x - min)
f(x) = --------------  + a
          max - min

You can verify that putting in min for x now gives a, and putting in max gives b.

You might also notice that (b-a)/(max-min) is a scaling factor between the size of the new range and the size of the original range. So really we are first translating x by -min, scaling it to the correct factor, and then translating it back up to the new minimum value of a.

Hope this helps.

Another option is:

filter1 = df.index.get_level_values('A') == 1
filter2 = df.index.get_level_values('B') == 4

df.iloc[filter1 & filter2]
Out[11]:
     0
A B
1 4  1

I found that setting the file's Copy To Output Directory parameter to Copy Always seems to have cleared up the locking issue. Although now I have 2 copies of the files and need to delete one.

In C++11, the using keyword when used for type alias is identical to typedef.

7.1.3.2

A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.

Bjarne Stroustrup provides a practical example:

typedef void (*PFD)(double);    // C style typedef to make `PFD` a pointer to a function returning void and accepting double
using PF = void (*)(double);    // `using`-based equivalent of the typedef above
using P = [](double)->void; // using plus suffix return type, syntax error
using P = auto(double)->void // Fixed thanks to DyP

Pre-C++11, the using keyword can bring member functions into scope. In C++11, you can now do this for constructors (another Bjarne Stroustrup example):

class Derived : public Base { 
public: 
    using Base::f;    // lift Base's f into Derived's scope -- works in C++98
    void f(char);     // provide a new f 
    void f(int);      // prefer this f to Base::f(int) 

    using Base::Base; // lift Base constructors Derived's scope -- C++11 only
    Derived(char);    // provide a new constructor 
    Derived(int);     // prefer this constructor to Base::Base(int) 
    // ...
}; 

Ben Voight provides a pretty good reason behind the rationale of not introducing a new keyword or new syntax. The standard wants to avoid breaking old code as much as possible. This is why in proposal documents you will see sections like Impact on the Standard, Design decisions, and how they might affect older code. There are situations when a proposal seems like a really good idea but might not have traction because it would be too difficult to implement, too confusing, or would contradict old code.

Here is an old paper from 2003 n1449. The rationale seems to be related to templates. Warning: there may be typos due to copying over from PDF.

First let’s consider a toy example:

template <typename T>
class MyAlloc {/*...*/};

template <typename T, class A>
class MyVector {/*...*/};

template <typename T>

struct Vec {
typedef MyVector<T, MyAlloc<T> > type;
};
Vec<int>::type p; // sample usage

The fundamental problem with this idiom, and the main motivating fact for this proposal, is that the idiom causes the template parameters to appear in non-deducible context. That is, it will not be possible to call the function foo below without explicitly specifying template arguments.

template <typename T> void foo (Vec<T>::type&);

So, the syntax is somewhat ugly. We would rather avoid the nested ::type We’d prefer something like the following:

template <typename T>
using Vec = MyVector<T, MyAlloc<T> >; //defined in section 2 below
Vec<int> p; // sample usage

Note that we specifically avoid the term “typedef template” and introduce the new syntax involving the pair “using” and “=” to help avoid confusion: we are not defining any types here, we are introducing a synonym (i.e. alias) for an abstraction of a type-id (i.e. type expression) involving template parameters. If the template parameters are used in deducible contexts in the type expression then whenever the template alias is used to form a template-id, the values of the corresponding template parameters can be deduced – more on this will follow. In any case, it is now possible to write generic functions which operate on Vec<T> in deducible context, and the syntax is improved as well. For example we could rewrite foo as:

template <typename T> void foo (Vec<T>&);

We underscore here that one of the primary reasons for proposing template aliases was so that argument deduction and the call to foo(p) will succeed.

The follow-up paper n1489 explains why using instead of using typedef:

It has been suggested to (re)use the keyword typedef — as done in the paper [4] — to introduce template aliases:

template<class T> 
    typedef std::vector<T, MyAllocator<T> > Vec;

That notation has the advantage of using a keyword already known to introduce a type alias. However, it also displays several disavantages among which the confusion of using a keyword known to introduce an alias for a type-name in a context where the alias does not designate a type, but a template; Vec is not an alias for a type, and should not be taken for a typedef-name. The name Vec is a name for the family std::vector< [bullet] , MyAllocator< [bullet] > > – where the bullet is a placeholder for a type-name. Consequently we do not propose the “typedef” syntax. On the other hand the sentence

template<class T>
    using Vec = std::vector<T, MyAllocator<T> >;

can be read/interpreted as: from now on, I’ll be using Vec<T> as a synonym for std::vector<T, MyAllocator<T> >. With that reading, the new syntax for aliasing seems reasonably logical.

I think the important distinction is made here, aliases instead of types. Another quote from the same document:

An alias-declaration is a declaration, and not a definition. An alias- declaration introduces a name into a declarative region as an alias for the type designated by the right-hand-side of the declaration. The core of this proposal concerns itself with type name aliases, but the notation can obviously be generalized to provide alternate spellings of namespace-aliasing or naming set of overloaded functions (see ? 2.3 for further discussion). [My note: That section discusses what that syntax can look like and reasons why it isn't part of the proposal.] It may be noted that the grammar production alias-declaration is acceptable anywhere a typedef declaration or a namespace-alias-definition is acceptable.

Summary, for the role of using:

• template aliases (or template typedefs, the former is preferred namewise)
• namespace aliases (i.e., namespace PO = boost::program_options and using PO = ... equivalent)
• the document says A typedef declaration can be viewed as a special case of non-template alias-declaration. It's an aesthetic change, and is considered identical in this case.
• bringing something into scope (for example, namespace std into the global scope), member functions, inheriting constructors

It cannot be used for:

int i;
using r = i; // compile-error

Instead do:

using r = decltype(i);

Naming a set of overloads.

// bring cos into scope
using std::cos;

// invalid syntax
using std::cos(double);

// not allowed, instead use Bjarne Stroustrup function pointer alias example
using test = std::cos(double);

in swift 5 we do like, Use typealias for the completion. Typlealias nothing just use to clean the code.

typealias response = (Bool,Any?)->()


static func postCall(_ url : String, param : [String : Any],completion : @escaping response){
    Alamofire.request(url, method: .post, parameters: param, encoding: JSONEncoding.default, headers: [:]).responseJSON { (response) in

        switch response.result {
           case .success(let JSON):
               print("\n\n Success value and JSON: \(JSON)")

           case .failure(let error):
               print("\n\n Request failed with error: \(error)")

           }
    }
}

You can use aggregate to calculate the means:

means<-aggregate(df,by=list(df$gender),mean)
Group.1      tea     coke     beer    water gender
1       1 87.70171 27.24834 24.27099 37.24007      1
2       2 24.73330 25.27344 25.64657 24.34669      2

Get rid of the Group.1 column

means<-means[,2:length(means)]

Then you have reformat the data to be in long format:

library(reshape2)
means.long<-melt(means,id.vars="gender")
  gender variable    value
1      1      tea 87.70171
2      2      tea 24.73330
3      1     coke 27.24834
4      2     coke 25.27344
5      1     beer 24.27099
6      2     beer 25.64657
7      1    water 37.24007
8      2    water 24.34669

Finally, you can use ggplot2 to create your plot:

library(ggplot2)
ggplot(means.long,aes(x=variable,y=value,fill=factor(gender)))+
  geom_bar(stat="identity",position="dodge")+
  scale_fill_discrete(name="Gender",
                      breaks=c(1, 2),
                      labels=c("Male", "Female"))+
  xlab("Beverage")+ylab("Mean Percentage")

$('#selector').delay(5000).fadeOut('slow');

An asynchronously loaded script is likely going to run AFTER the document has been fully parsed and closed. Thus, you can't use document.write() from such a script (well technically you can, but it won't do what you want).

You will need to replace any document.write() statements in that script with explicit DOM manipulations by creating the DOM elements and then inserting them into a particular parent with .appendChild() or .insertBefore() or setting .innerHTML or some mechanism for direct DOM manipulation like that.

For example, instead of this type of code in an inline script:

<div id="container">
<script>
document.write('<span style="color:red;">Hello</span>');
</script>
</div>

You would use this to replace the inline script above in a dynamically loaded script:

var container = document.getElementById("container");
var content = document.createElement("span");
content.style.color = "red";
content.innerHTML = "Hello";
container.appendChild(content);

Or, if there was no other content in the container that you needed to just append to, you could simply do this:

var container = document.getElementById("container");
container.innerHTML = '<span style="color:red;">Hello</span>';

The other answers didn't seem to work for me, but I found this hack. This worked for me (July 2014)

select {
-moz-appearance: textfield !important;
    }

In my case, I also had a woocommerce input field so I used this

.woocommerce .quantity input.qty {
-moz-appearance: textfield !important;
 }

Updated my answer to show select rather than input

git pull origin master will pull changes from the origin remote, master branch and merge them to the local checked-out branch.

git pull origin/master will pull changes from the locally stored branch origin/master and merge that to the local checked-out branch. The origin/master branch is essentially a "cached copy" of what was last pulled from origin, which is why it's called a remote branch in git parlance. This might be somewhat confusing.

You can see what branches are available with git branch and git branch -r to see the "remote branches".

You can achieve the opening/closing of a tab by the combination of keys COMMAND + T or COMMAND + W (OSX). On other OSs you can use CONTROL + T / CONTROL + W.

In selenium you can emulate such behavior. You will need to create one webdriver and as many tabs as the tests you need.

Here it is the code.

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://www.google.com/")

#open tab
driver.find_element_by_tag_name('body').send_keys(Keys.COMMAND + 't') 
# You can use (Keys.CONTROL + 't') on other OSs

# Load a page 
driver.get('http://stackoverflow.com/')
# Make the tests...

# close the tab
# (Keys.CONTROL + 'w') on other OSs.
driver.find_element_by_tag_name('body').send_keys(Keys.COMMAND + 'w') 


driver.close()

break is to break out of a loop like for, while, switch etc which you don't have here, you need to use return to break the execution flow of the current function and return to the caller.

function loop() {
    if (isPlaying) {
        jet1.draw();
        drawAllEnemies();
        requestAnimFrame(loop);
        if (game == 1) {
           return
        }
    }
}

Note: This does not cover the logic behind the if condition or when to return from the method, for that we need to have more context regarding the drawAllEnemies and requestAnimFrame method as well as how game value is updated

Why not override the function? In that case you can always be sure it returns 0 in case of NaN:

(function(original) {
    parseInt = function() {
        return original.apply(window, arguments) || 0;
    };
})(parseInt);

Now, anywhere in your code:

parseInt('') === 0

You want something like:

<appSettings>
  <add key="developmentModeUserId" xdt:Transform="Remove" xdt:Locator="Match(key)"/>
  <add key="developmentMode" value="false" xdt:Transform="SetAttributes"
          xdt:Locator="Match(key)"/>
</appSettings>

If it's a UI based application , then " I also need to know what I need to add to my code so that my program waits about 700 milliseconds for a keyinput before moving on to another method" you can use GlassPane or Timer class to fulfill the requirement.

For key Event:

public void keyPressed(KeyEvent e) {

    int key = e.getKeyCode();

    if (key == KeyEvent.VK_LEFT) {
        dx = -1;
    }

    if (key == KeyEvent.VK_RIGHT) {
        dx = 1;
    }

    if (key == KeyEvent.VK_UP) {
        dy = -1;
    }

    if (key == KeyEvent.VK_DOWN) {
        dy = 1;
    }
}

Also one can use this:

{% if forloop.first %}

or

{% if forloop.last %}

A useful alternative answer to the first question, using the examples from tomeedee’s answer, would be to use numpy’s vstack and column_stack methods:

Given a matrix p,

>>> import numpy as np
>>> p = np.array([ [1,2] , [3,4] ])

an augmented matrix can be generated by:

>>> p = np.vstack( [ p , [5 , 6] ] )
>>> p = np.column_stack( [ p , [ 7 , 8 , 9 ] ] )
>>> p
array([[1, 2, 7],
       [3, 4, 8],
       [5, 6, 9]])

These methods may be convenient in practice than np.append() as they allow 1D arrays to be appended to a matrix without any modification, in contrast to the following scenario:

>>> p = np.array([ [ 1 , 2 ] , [ 3 , 4 ] , [ 5 , 6 ] ] )
>>> p = np.append( p , [ 7 , 8 , 9 ] , 1 )
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/dist-packages/numpy/lib/function_base.py", line 3234, in append
    return concatenate((arr, values), axis=axis)
ValueError: arrays must have same number of dimensions

In answer to the second question, a nice way to remove rows and columns is to use logical array indexing as follows:

Given a matrix p,

>>> p = np.arange( 20 ).reshape( ( 4 , 5 ) )

suppose we want to remove row 1 and column 2:

>>> r , c = 1 , 2
>>> p = p [ np.arange( p.shape[0] ) != r , : ] 
>>> p = p [ : , np.arange( p.shape[1] ) != c ]
>>> p
array([[ 0,  1,  3,  4],
       [10, 11, 13, 14],
       [15, 16, 18, 19]])

Note - for reformed Matlab users - if you wanted to do these in a one-liner you need to index twice:

>>> p = np.arange( 20 ).reshape( ( 4 , 5 ) )    
>>> p = p [ np.arange( p.shape[0] ) != r , : ] [ : , np.arange( p.shape[1] ) != c ]

This technique can also be extended to remove sets of rows and columns, so if we wanted to remove rows 0 & 2 and columns 1, 2 & 3 we could use numpy's setdiff1d function to generate the desired logical index:

>>> p = np.arange( 20 ).reshape( ( 4 , 5 ) )
>>> r = [ 0 , 2 ]
>>> c = [ 1 , 2 , 3 ]
>>> p = p [ np.setdiff1d( np.arange( p.shape[0] ), r ) , : ] 
>>> p = p [ : , np.setdiff1d( np.arange( p.shape[1] ) , c ) ]
>>> p
array([[ 5,  9],
       [15, 19]])

please check if code below would work for you; it iterates through cells of the datagris's first column and checks if cell content equals to the textbox.text value and selects the row.

for (int i = 0; i < dataGrid.Items.Count; i++)
{
    DataGridRow row = (DataGridRow)dataGrid.ItemContainerGenerator.ContainerFromIndex(i);
    TextBlock cellContent = dataGrid.Columns[0].GetCellContent(row) as TextBlock;
    if (cellContent != null && cellContent.Text.Equals(textBox1.Text))
    {
        object item = dataGrid.Items[i];
        dataGrid.SelectedItem = item;
        dataGrid.ScrollIntoView(item);
        row.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));
        break;
    }
}

hope this helps, regards

each passes into your function index and element. Check index against the length of the set and you're good to go:

var set = $('.requiredText');
var length = set.length;
set.each(function(index, element) {
      thisVal = $(this).val();
      if(parseInt(thisVal) !== 0) {
          console.log('Valid Field: ' + thisVal);
          if (index === (length - 1)) {
              console.log('Last field, submit form here');
          }
      }
});

The official length according to the offical Apache docs is 8,192, but many folks have run into trouble at ~4,000.

MS Internet Explorer is usually the limiting factor anyway, as it caps the maximum URL size at 2,048.

The json.load() method (without "s" in "load") can read a file directly:

import json
with open('strings.json') as f:
    d = json.load(f)
    print(d)

json.loads() method, which is used for string arguments only.

import json

person = '{"name": "Bob", "languages": ["English", "Fench"]}'
print(type(person))
# Output : <type 'str'>

person_dict = json.loads(person)
print( person_dict)
# Output: {'name': 'Bob', 'languages': ['English', 'Fench']}

print(type(person_dict))
# Output : <type 'dict'>

Here , we can see after using loads() takes a string ( type(str) ) as a input and return dictionary.

I believe this will work:

TextArea.Text = "Line 1" & vbCrLf & "Line 2"

System.Environment.NewLine could be used in place of vbCrLf if you wanted to be a little less VB6 about it.

To expand on the above answers, the following can be used to remove multiple elements from an array, without partial matching:

ARRAY=(one two onetwo three four threefour "one six")
TO_REMOVE=(one four)

TEMP_ARRAY=()
for pkg in "${ARRAY[@]}"; do
    for remove in "${TO_REMOVE[@]}"; do
        KEEP=true
        if [[ ${pkg} == ${remove} ]]; then
            KEEP=false
            break
        fi
    done
    if ${KEEP}; then
        TEMP_ARRAY+=(${pkg})
    fi
done
ARRAY=("${TEMP_ARRAY[@]}")
unset TEMP_ARRAY

This will result in an array containing: (two onetwo three threefour "one six")

This is the first of my two answers to the question.

If you want fine control over the namespaces - for example if you want to omit some of them but not others, or if you want to replace one namespace with another, you can do this using XmlAttributeOverrides.

Suppose you have this type definition:

// explicitly specify a namespace for this type,
// to be used during XML serialization.
[XmlRoot(Namespace="urn:Abracadabra")]
public class MyTypeWithNamespaces
{
    // private fields backing the properties
    private int _Epoch;
    private string _Label;

    // explicitly define a distinct namespace for this element
    [XmlElement(Namespace="urn:Whoohoo")]
    public string Label
    {
        set {  _Label= value; } 
        get { return _Label; } 
    }

    // this property will be implicitly serialized to XML using the
    // member name for the element name, and inheriting the namespace from
    // the type.
    public int Epoch
    {
        set {  _Epoch= value; } 
        get { return _Epoch; } 
    }
}

And this serialization pseudo-code:

        var o2= new MyTypeWithNamespaces() { ..initializers...};
        ns.Add( "", "urn:Abracadabra" );
        XmlSerializer s2 = new XmlSerializer(typeof(MyTypeWithNamespaces));
        s2.Serialize(System.Console.Out, o2, ns);

You would get something like this XML:

<MyTypeWithNamespaces xmlns="urn:Abracadabra">
  <Label xmlns="urn:Whoohoo">Cimsswybclaeqjh</Label>
  <Epoch>97</Epoch>
</MyTypeWithNamespaces>

Notice that there is a default namespace on the root element, and there is also a distinct namespace on the "Label" element. These namespaces were dictated by the attributes decorating the type, in the code above.

The Xml Serialization framework in .NET includes the possibility to explicitly override the attributes that decorate the actual code. You do this with the XmlAttributesOverrides class and friends. Suppose I have the same type, and I serialize it this way:

        // instantiate the container for all attribute overrides
        XmlAttributeOverrides xOver = new XmlAttributeOverrides();

        // define a set of XML attributes to apply to the root element
        XmlAttributes xAttrs1 = new XmlAttributes();

        // define an XmlRoot element (as if [XmlRoot] had decorated the type)
        // The namespace in the attribute override is the empty string. 
        XmlRootAttribute xRoot = new XmlRootAttribute() { Namespace = ""};

        // add that XmlRoot element to the container of attributes
        xAttrs1.XmlRoot= xRoot;

        // add that bunch of attributes to the container holding all overrides
        xOver.Add(typeof(MyTypeWithNamespaces), xAttrs1);

        // create another set of XML Attributes
        XmlAttributes xAttrs2 = new XmlAttributes();

        // define an XmlElement attribute, for a type of "String", with no namespace
        var xElt = new XmlElementAttribute(typeof(String)) { Namespace = ""};

        // add that XmlElement attribute to the 2nd bunch of attributes
        xAttrs2.XmlElements.Add(xElt);

        // add that bunch of attributes to the container for the type, and
        // specifically apply that bunch to the "Label" property on the type.
        xOver.Add(typeof(MyTypeWithNamespaces), "Label", xAttrs2);

        // instantiate a serializer with the overrides 
        XmlSerializer s3 = new XmlSerializer(typeof(MyTypeWithNamespaces), xOver);

        // serialize
        s3.Serialize(System.Console.Out, o2, ns2);

The result looks like this;

<MyTypeWithNamespaces>
  <Label>Cimsswybclaeqjh</Label>
  <Epoch>97</Epoch>
</MyTypeWithNamespaces>

You have stripped the namespaces.

A logical question is, can you strip all namespaces from arbitrary types during serialization, without going through the explicit overrides? The answer is YES, and how to do it is in my next response.

INSERT INTO Test([col1],[col2]) (
    SELECT 
        a.Name AS [col1],

For those of you who with Nexus 5x who only see Kedacom usb device in Device Manager and cannot get adb to see the phone...the trick is to Update driver... on the Kedacom device and change it to "Android ADB interface/device"

Objective-C

You have to give the values between 0 and 1.0. So divide the RGB values by 255.

myLabel.textColor= [UIColor colorWithRed:(160/255.0) green:(97/255.0) blue:(5/255.0) alpha:1] ;

Update:

You can also use this macro

#define Rgb2UIColor(r, g, b)  [UIColor colorWithRed:((r) / 255.0) green:((g) / 255.0) blue:((b) / 255.0) alpha:1.0]

and you can call in any of your class like this

 myLabel.textColor = Rgb2UIColor(160, 97, 5);

Swift

This is the normal color synax

myLabel.textColor = UIColor(red: (160/255.0), green: (97/255.0), blue: (5/255.0), alpha: 1.0) 
//The values should be between 0 to 1

Swift is not much friendly with macros

Complex macros are used in C and Objective-C but have no counterpart in Swift. Complex macros are macros that do not define constants, including parenthesized, function-like macros. You use complex macros in C and Objective-C to avoid type-checking constraints or to avoid retyping large amounts of boilerplate code. However, macros can make debugging and refactoring difficult. In Swift, you can use functions and generics to achieve the same results without any compromises. Therefore, the complex macros that are in C and Objective-C source files are not made available to your Swift code.

So we use extension for this

extension UIColor {
    convenience init(_ r: Double,_ g: Double,_ b: Double,_ a: Double) {
        self.init(red: r/255, green: g/255, blue: b/255, alpha: a)
    }
}

You can use it like

myLabel.textColor = UIColor(160.0, 97.0, 5.0, 1.0)

Here is the complete programme please check this

static void Main(string[] args)
{
    List<string> li = new List<string>();
    li.Add("Ram");
    li.Add("shyam");
    li.Add("Ram");
    li.Add("Kumar");
    li.Add("Kumar");

    var x = from obj in li group obj by obj into g select new { Name = g.Key, Duplicatecount = g.Count() };
    foreach(var m in x)
    {
        Console.WriteLine(m.Name + "--" + m.Duplicatecount);
    }
    Console.ReadLine();
}        

This helped in my case:

cmdkey.exe /add:<targetname> /user:<username> /pass:<password>
psexec.exe \\<targetname> <remote_command>

table { 
  border-spacing: 10px; 
} 

This worked for me once I removed

border-collapse: separate;

from my table tag.

You can also add underscore.js to your project and will be able to do it in one line:

_.map($("input[name='category_ids[]']:checked"), function(el){return $(el).val()})

Quite a few applications seem to implement Steganography on JPEG, so it's feasible:

http://www.jjtc.com/Steganography/toolmatrix.htm

Here's an article regarding a relevant algorithm (PM1) to get you started:

http://link.springer.com/article/10.1007%2Fs00500-008-0327-7#page-1

If you have a List of objects, you can serialize them to JSON as follow:

List<MyObjectClass> listOfObjects = new List<MyObjectClass>();

And then use addParameter:

requestREST.AddParameter("myAssocKey", JsonConvert.SerializeObject(listOfObjects));

And you wil need to set the request format to JSON:

requestREST.RequestFormat = DataFormat.Json;

You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:

import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values

... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.

Recently, I had the same problem within .NET 3.5 (no dynamic available). Here is how I solved:

// pass anonymous object as argument
var args = new { Title = "Find", Type = typeof(FindCondition) };

using (frmFind f = new frmFind(args)) 
{
...
...
}

Adapted from somewhere on stackoverflow:

// Use a custom cast extension
public static T CastTo<T>(this Object x, T targetType)
{
   return (T)x;
}

Now get back the object via cast:

public partial class frmFind: Form
{
    public frmFind(object arguments)
    {

        InitializeComponent();

        var args = arguments.CastTo(new { Title = "", Type = typeof(Nullable) });

        this.Text = args.Title;

        ...
    }
    ...
}

I referenced @benjamin-hubbard 's answer above to parse the output of dnscmd for A records, and generate a PHP "dictionary"/key-value pairs of IPs and Hostnames. I strung multiple -replace args together to replace text with nothing or tab to format the data for the PHP file.

$DnsDataClean = $DnsData `
    -match "^[a-zA-Z0-9].+\sA\s.+" `
    -replace "172\.30\.","`$P." `
    -replace "\[.*\] " `
    -replace "\s[0-9]+\sA\s","`t"

$DnsDataTable = ( $DnsDataClean | `
    ForEach-Object { 
        $HostName = ($_ -split "\t")[0] ; 
        $IpAddress = ($_ -split "\t")[1] ; 
        "`t`"$IpAddress`"`t=>`t'$HostName', `n" ;
    } | sort ) + "`t`"`$P.255.255`"`t=>`t'None'"

`$P = '10.213';
`$IpHostArr = [`n`n$DnsDataTable`n];

optional parameters are nothing but default parameters! i suggest you give both of them default parameters. GetFooBar(int a=0, int b=0) if you don't have any overloaded method, will result in a=0, b=0 if you don't pass any values,if you pass 1 value, will result in, passed value for a, 0 and if you pass 2 values 1st will be assigned to a and second to b.

hope that answers your question.

I think the core issue with Flask is that stdout gets buffered. I was able to print with print('Hi', flush=True). You can also disable buffering by setting the PYTHONUNBUFFERED environment variable (to any non-empty string).

Hat tip to Adam Bien if you don't want to use createQuery with a String and want type safety:

 @PersistenceContext
 EntityManager em;

 public List<ConfigurationEntry> allEntries() {
        CriteriaBuilder cb = em.getCriteriaBuilder();
        CriteriaQuery<ConfigurationEntry> cq = cb.createQuery(ConfigurationEntry.class);
        Root<ConfigurationEntry> rootEntry = cq.from(ConfigurationEntry.class);
        CriteriaQuery<ConfigurationEntry> all = cq.select(rootEntry);
        TypedQuery<ConfigurationEntry> allQuery = em.createQuery(all);
        return allQuery.getResultList();
 }

If there is a null in an array and you want to avoid it:

db.test.find({"contain" : {$ne :[] }}).pretty()

This is a version of Ben James's answer, above:

>>> import datetime
>>> x = datetime.date.today()
>>> print x
2013-01-11
>>> 
>>> 
>>> print "Today's date is %s ..." % x
Today's date is 2013-01-11 ...
>>> 
>>> print "Today's date is %r ..." % x
Today's date is datetime.date(2013, 1, 11) ...
>>>

When I ran this, it helped me see the usefulness of %r.

If you are just setting defaults for certain attributes of a database backed model I'd consider using sql default column values - can you clarify what types of defaults you are using?

There are a number of approaches to handle it, this plugin looks like an interesting option.

<a href="<?php echo $_SERVER['DOCUMENT_ROOT'].'/hello.html'; ?>">go with php</a>
    <br />
<a href="/hello.html">go to with html</a>

Try this yourself and find that they are not exactly the same.

$_SERVER['DOCUMENT_ROOT'] renders an actual file path (on my computer running as it's own server, C:/wamp/www/

HTML's / renders the root of the server url, in my case, localhost/

But C:/wamp/www/hello.html and localhost/hello.html are in fact the same file

This query is for add data from one table to another table using foreign key

Beware of using string interpolation for SQL queries, since it won't escape the input parameters correctly and will leave your application open to SQL injection vulnerabilities. The difference might seem trivial, but in reality it's huge.

Incorrect (with security issues)

c.execute("SELECT * FROM foo WHERE bar = %s AND baz = %s" % (param1, param2))

Correct (with escaping)

c.execute("SELECT * FROM foo WHERE bar = %s AND baz = %s", (param1, param2))

It adds to the confusion that the modifiers used to bind parameters in a SQL statement varies between different DB API implementations and that the mysql client library uses printf style syntax instead of the more commonly accepted '?' marker (used by eg. python-sqlite).

Is it acceptable & safe to run pip install under sudo?

It's not safe and it's being frowned upon – see What are the risks of running 'sudo pip'? To install Python package in your home directory you don't need root privileges. See description of --user option to pip.

POCOs(Plain old CLR objects) are simply entities of your Domain. Normally when we use entity framework the entities are generated automatically for you. This is great but unfortunately these entities are interspersed with database access functionality which is clearly against the SOC (Separation of concern). POCOs are simple entities without any data access functionality but still gives the capabilities all EntityObject functionalities like

• Lazy loading
• Change tracking

Here is a good start for this

POCO Entity framework

You can also generate POCOs so easily from your existing Entity framework project using Code generators.

EF 5.X DbContext code generator

I'm not aware of anything like a single table that lets you compare all of them in at one glance (I'm not sure such a table would even be feasible).

Of course the ISO standard document enumerates the complexity requirements in detail, sometimes in various rather readable tables, other times in less readable bullet points for each specific method.

Also the STL library reference at http://www.cplusplus.com/reference/stl/ provides the complexity requirements where appropriate.

You need to name your outer loop and break that loop, rather than your inner loop - like this.

outer_loop: 
for(i=0;i<5;i++) {
    for(j=i+1;j<5;j++) {
        break outer_loop;
    }
    alert(1);
}

You can use new stdClass() (which is recommended):

$obj_a = new stdClass();
$obj_a->name = "John";
print_r($obj_a);

// outputs:
// stdClass Object ( [name] => John ) 

Or you can convert an empty array to an object which produces a new empty instance of the stdClass built-in class:

$obj_b = (object) [];
$obj_b->name = "John";
print_r($obj_b);

// outputs: 
// stdClass Object ( [name] => John )  

Or you can convert the null value to an object which produces a new empty instance of the stdClass built-in class:

$obj_c = (object) null;
$obj_c->name = "John";
print($obj_c);

// outputs:
// stdClass Object ( [name] => John )

wait and sleep methods are very different:

• sleep has no way of "waking-up",
• whereas wait has a way of "waking-up" during the wait period, by another thread calling notify or notifyAll.

Come to think about it, the names are confusing in that respect; however sleep is a standard name and wait is like the WaitForSingleObject or WaitForMultipleObjects in the Win API.

The insert statement actually has a syntax for doing just that. It's a lot easier if you specify the column names rather than selecting "*" though:

INSERT INTO new_table (Foo, Bar, Fizz, Buzz)
SELECT Foo, Bar, Fizz, Buzz
FROM initial_table
-- optionally WHERE ...

I'd better clarify this because for some reason this post is getting a few down-votes.

The INSERT INTO ... SELECT FROM syntax is for when the table you're inserting into ("new_table" in my example above) already exists. As others have said, the SELECT ... INTO syntax is for when you want to create the new table as part of the command.

You didn't specify whether the new table needs to be created as part of the command, so INSERT INTO ... SELECT FROM should be fine if your destination table already exists.

The error:

'int' object has no attribute '__getitem__'

means that you're attempting to apply the index operator [] on an int, not a list. So is col not a list, even when it should be? Let's start from that.

Look here:

col = [[0 for col in range(5)] for row in range(6)]

Use a different variable name inside, looks like the list comprehension overwrites the col variable during iteration. (Not during the iteration when you set col, but during the following ones.)

Although you should have no problem running a 2005 instance of the database engine beside a 2008 instance, The tools are installed into a shared directory, so you can't have two versions of the tools installed. Fortunately, the 2008 tools are backwards-compatible. As we speak, I'm using SSMS 2008 and Profiler 2008 to manage my 2005 Express instances. Works great.

Before installing the 2008 tools, you need to remove any and all "shared" components from 2005. Try going to your Add/Remove programs control panel, find Microsoft SQL Server 2005, and click "Change." Then choose "Workstation Components" and remove everything there (this will not remove your database engine).

I believe the 2008 installer also has an option to upgrade shared components only. You might try that. Good luck!

The problem is likely to lie with the line:

window.onload = onPageLoad();

By including the brackets you are saying onload should equal the return value of onPageLoad(). For example:

/*Example function*/
function onPageLoad()
{
    return "science";
}
/*Set on load*/
window.onload = onPageLoad()

If you print out the value of window.onload to the console it will be:

science

The solution is remove the brackets:

window.onload = onPageLoad;

So, you're using onPageLoad as a reference to the so-named function.

Finally, in order to get the response value you'll need a readystatechange listener for your XMLHttpRequest object, since it's asynchronous:

xmlDoc = xmlhttp.responseXML;
parser = new DOMParser(); // This code is untested as it doesn't run this far.

Here you add the listener:

xmlHttp.onreadystatechange = function() {
    if(this.readyState == 4) {
        // Do something
    }
}

for (var i = 0; i < widthRange.length; ++i) {
  if (widthRange[i] != null) {
    // do something
  }
}

You can't really get just the keys you've set because that's not how an Array works. Once you set element 46, you also have 0 through 45 set too (though they're null).

You could always have two arrays:

var widthRange = [], widths = [], newVal = function(n) {
  widths.push(n);
  return n;
};
widthRange[newVal(26)] = { whatever: "hello there" };

for (var i = 0; i < widths.length; ++i) {
  doSomething(widthRange[widths[i]]);
}

edit well it may be that I'm all wet here ...

I had to fix this by decreasing the priority (making it higher). This caused an immediate response. Not what I was expecting, but it worked.

Yet another solution:

I was stumped because I was including boost_regex-vc120-mt-gd-1_58.lib in my Link->Additional Dependencies property, but the link kept telling me it couldn't open libboost_regex-vc120-mt-gd-1_58.lib (note the lib prefix). I didn't specify libboost_regex-vc120-mt-gd-1_58.lib.

I was trying to use (and had built) the boost dynamic libraries (.dlls) but did not have the BOOST_ALL_DYN_LINK macro defined. Apparently there are hints in the compile to include a library, and without BOOST_ALL_DYN_LINK it looks for the static library (with the lib prefix), not the dynamic library (without a lib prefix).

On Mac OS you can use: CMD + CTRL + G

If none of the other answers work for you, here's what worked for me.

Restart eclipse

I had source folder configured correctly, and unit tests correctly annotated but was still getting "No JUnit tests found", for one project. After a restart it worked. I was using STS 3.6.2 based of eclipse Luna 4.4.1

You need to install the python-setuptools package:

apt-get install python-setuptools on Debian-ish systems yum install python-setuptools on Redhat-ish systems

Use sudo if applicable

I am not sure but you can try intialising handler to null in onDestroy()

import java.util.Date;
import java.text.SimpleDateFormat;

...
Date currentMonth = new Date();
String yyyyMM = new SimpleDateFormat("yyyyMM").format(currentMonth);
Date firstDateOfMonth = new SimpleDateFormat("yyyyMM").parse(yyyyMM);
...

my stupid solution. but it's work for me :D

It's worth subscribing to the Google Tech Talk YouTube channel. It's a video podcast with a bunch of really interesting, wide-ranging talks given to Google but (usually) outside speakers.

Past presenters include Linus Torvals, Guido van Rossum, Merlin Mann and Larry Wall. The video is usually just the slides so (depending on the speaker) you might not need to watch.

By default, most of distribution uses Ctrl+F12.

Some OS distribution (in my case Xubuntu) which uses Xcfe, overrides Ctrl+F12 to "Workspace 12" switch.

Try this simple class for customizing a dialog to your liking:

import java.util.ArrayList;
import java.util.List;

import javax.swing.JComponent;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JRootPane;

In my experience, I always just use an external program to generate the graph (mathematica, gnuplot, matlab, etc.) and export the graph as a pdf or eps file. Then I include it into the document with includegraphics.

I tried following format, working fine

*/5 * * * * wget --quiet -O /dev/null http://localhost/cron.php

If you use mod_rewrite to hide the extension of your scripts, or if you just like pretty URLs that end in /, then you might want to approach this from the other direction. Tell nginx to let anything with a non-static extension to go through to apache. For example:

location ~* ^.+\.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|pdf|txt|tar|wav|bmp|rtf|js|flv|swf|html|htm)$
{
    root   /path/to/static-content;
}

location ~* ^!.+\.(jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar|bz2|pdf|txt|tar|wav|bmp|rtf|js|flv|swf|html|htm)$ {
    if (!-f $request_filename) {
        return 404;
    }
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://127.0.0.1:8080;
}

I found the first part of this snippet over at: http://code.google.com/p/scalr/wiki/NginxStatic

You can do this with background-size:

html {
    background: url(images/bg.jpg) no-repeat center center fixed; 
    background-size: cover;
}

There are a lot of values other than cover that you can set background-size to, see which one works for you: https://developer.mozilla.org/en-US/docs/Web/CSS/background-size

Spec: https://www.w3.org/TR/css-backgrounds-3/#the-background-size

It works in all modern browsers: http://caniuse.com/#feat=background-img-opts

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

How it worked for me.

1 Start Android Device Monitor from Tools -> Android -> Android Device Monitor

2 Click on Stop for the process you are facing the issue from list of devices.

try backgroundPosition:"(-20px 0)"

Just to double check are you referencing this the background position plugin?

Example of it on jsfiddle with the background position plugin.

Put the line in a stringstream and extract word by word back:

#include <iostream>
#include <sstream>
using namespace std;

int main()
{
    string t;
    getline(cin,t);

    istringstream iss(t);
    string word;
    while(iss >> word) {
        /* do stuff with word */
    }
}

Of course, you can just skip the getline part and read word by word from cin directly.

And here you can read why is using namespace std considered bad practice.

By default there are no constraints on the foreign key, foreign key can be null and duplicate.

while creating a table / altering the table, if you add any constrain of uniqueness or not null then only it will not allow the null/ duplicate values.

...We don't have a newer version of MySQL yet, so I was able to do this (works only on UNIX):

 host=maindb

 echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Locked

The above will query for all locked sessions, and return the information and SQL that is involved.

...So- assuming you wanted to query for sessions that were sleeping:

  host=maindb

  echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Sleep

Or, assuming you needed to provide additional connection parameters for MySQL:

  host=maindb

  user=me

  password=mycoolpassword 

  echo "show full processlist\G" | mysql -h$host -u$user -p$password | grep -B 6 -A 1 Locked

With a couple of tweaks, I'm sure a shell script could be easily created to query the processlist the way you want it.

Here's a java example using DesiredCapabilities. I used it for pumping selenium tests into jmeter. (was only interested in HTTP requests)

import org.openqa.selenium.Proxy;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;

String myProxy = "localhost:7777";  //example: proxy host=localhost port=7777
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(CapabilityType.PROXY,
                           new Proxy().setHttpProxy(myProxy));
WebDriver webDriver = new FirefoxDriver(capabilities); 

In Python 3.x, 5 / 2 will return 2.5 and 5 // 2 will return 2. The former is floating point division, and the latter is floor division, sometimes also called integer division.

In Python 2.2 or later in the 2.x line, there is no difference for integers unless you perform a from __future__ import division, which causes Python 2.x to adopt the 3.x behavior.

Regardless of the future import, 5.0 // 2 will return 2.0 since that's the floor division result of the operation.

You can find a detailed description at https://docs.python.org/whatsnew/2.2.html#pep-238-changing-the-division-operator

As the used variables from outside the lamda have to be (implicitly) final, you have to use something like AtomicInteger or write your own data structure.

See https://docs.oracle.com/javase/tutorial/java/javaOO/lambdaexpressions.html#accessing-local-variables.

It's != without type coercion. See the MDN documentation for comparison operators.

Also see this StackOverflow answer, which includes a quote from "JavaScript: The Good Parts" about the problems with == and !=. (null == undefined, false == "0", etc.)

Short answer: always use === and !== unless you have a compelling reason to do otherwise. (Tools like JSLint, JSHint, ESLint, etc. will give you this same advice.)

There is comma missing in your tuple.

insert the comma between the tuples as shown:

pack_size = (('1', '1'),('3', '3'),(b, b),(h, h),(d, d), (e, e),(r, r))

Do the same for all

because my array was like below: and I used .push function to create it dynamically

my_array = ["234", "23423"];

The only way I converted my array into json is

json = Object.assign({}, my_array);

With no plug-ins, this can be easier without using as much jQuery, instead going slightly more old-school:

var myOptions = {
    val1 : 'text1',
    val2 : 'text2'
};
$.each(myOptions, function(val, text) {
    $('#mySelect').append( new Option(text,val) );
});

If you want to specify whether or not the option a) is the default selected value, and b) should be selected now, you can pass in two more parameters:

    var defaultSelected = false;
    var nowSelected     = true;
    $('#mySelect').append( new Option(text,val,defaultSelected,nowSelected) );

you're using jQuery UI dialog, you could just style the modal to appear with the position fixed in the window so it doesn't pop-up out of view, negating the need to scroll. Other

An application consists of one or more processes. A process, in the simplest terms, is an executing program. One or more threads run in the context of the process. A thread is the basic unit to which the operating system allocates processor time. A thread can execute any part of the process code, including parts currently being executed by another thread. A fiber is a unit of execution that must be manually scheduled by the application. Fibers run in the context of the threads that schedule them.

I had this very similar error as following.

C:\wamp\www\myrepository [master]> git push
fatal: unable to access 'https://github.com/myaccount/myrepository.git/': Couldn't resolve host 'github.com'

Actually, the prompt message has told us where's wrong.

https://github.com/myaccount/myrepository.git/

When I check my github, I found my github repository's HTTPS url is

https://github.com/myaccount/myrepository.git

I don't know how this happened. The wrong url has been set up by installed Git Shell automatically.

Once I remove the '/' at the end, I can push successfully.

I've found the same thing, but only on emulators that have the Use Host GPU setting ticked. Try turning that off, you'll no longer see those warnings (and the emulator will run horribly, horribly slowly..)

In my experience those warnings are harmless. Notice that the "error" is EGL_SUCCESS, which would seem to indicate no error at all!

The accepted answer has it spot on, but if you might want to specify which class label should be assigned to a specific color or label you could do the following. I did a little label gymnastics with the colorbar, but making the plot itself reduces to a nice one-liner. This works great for plotting the results from classifications done with sklearn. Each label matches a (x,y) coordinate.

import matplotlib
import matplotlib.pyplot as plt
import numpy as np

x = [4,8,12,16,1,4,9,16]
y = [1,4,9,16,4,8,12,3]
label = [0,1,2,3,0,1,2,3]
colors = ['red','green','blue','purple']

fig = plt.figure(figsize=(8,8))
plt.scatter(x, y, c=label, cmap=matplotlib.colors.ListedColormap(colors))

cb = plt.colorbar()
loc = np.arange(0,max(label),max(label)/float(len(colors)))
cb.set_ticks(loc)
cb.set_ticklabels(colors)

Using a slightly modified version of this answer, one can generalise the above for N colors as follows:

import numpy as np
import matplotlib as mpl
import matplotlib.pyplot as plt

N = 23 # Number of labels

# setup the plot
fig, ax = plt.subplots(1,1, figsize=(6,6))
# define the data
x = np.random.rand(1000)
y = np.random.rand(1000)
tag = np.random.randint(0,N,1000) # Tag each point with a corresponding label    

# define the colormap
cmap = plt.cm.jet
# extract all colors from the .jet map
cmaplist = [cmap(i) for i in range(cmap.N)]
# create the new map
cmap = cmap.from_list('Custom cmap', cmaplist, cmap.N)

# define the bins and normalize
bounds = np.linspace(0,N,N+1)
norm = mpl.colors.BoundaryNorm(bounds, cmap.N)

# make the scatter
scat = ax.scatter(x,y,c=tag,s=np.random.randint(100,500,N),cmap=cmap,     norm=norm)
# create the colorbar
cb = plt.colorbar(scat, spacing='proportional',ticks=bounds)
cb.set_label('Custom cbar')
ax.set_title('Discrete color mappings')
plt.show()

Which gives:

This solution is using javascript to open a new window when a user clicks on your custom share button.

HTML:

<a href="#" onclick="share_fb('http://urlhere.com/test/55d7258b61707022e3050000');return false;" rel="nofollow" share_url="http://urlhere.com/test/55d7258b61707022e3050000" target="_blank">

  //using fontawesome
  <i class="uk-icon-facebook uk-float-left"></i>
    Share
</a>

and in your javascript file. note window.open params are (url, dialogue title, width, height)

function share_fb(url) {
  window.open('https://www.facebook.com/sharer/sharer.php?u='+url,'facebook-share-dialog',"width=626, height=436")
}

Is there also a way to invoke this feature (which based on answers is called the Task Scheduler) programatically [...]?

Task scheduler API on MSDN.

The problem is

listModel.addElement(listaRosa.getSelectedValue());
listModel.removeElement(listaRosa.getSelectedValue());

you may be adding an element and immediatly removing it since both add and remove operations are on the same listModel.

Try

private void aggiungiTitolareButtonActionPerformed(java.awt.event.ActionEvent evt) {                                                       

    DefaultListModel lm2 = (DefaultListModel) listaTitolari.getModel();
    DefaultListModel lm1  = (DefaultListModel) listaRosa.getModel();
    if(lm2 == null)
    {
        lm2 = new DefaultListModel();
        listaTitolari.setModel(lm2);
    }
    lm2.addElement(listaTitolari.getSelectedValue());
    lm1.removeElement(listaTitolari.getSelectedValue());        
} 

Try the clear property.

Remember that float removes an element from the document layout - so yes, in a way it is "interfering" with br and p tags, in the sense that it would basically be ignoring anything in the main flow layout.

Everything except for point 2 is correct. There are many different notations for signed ints, some implementations use the first, others use the last and yet others use something completely different. That all depends on the platform you're working with.

THIS WORK ALSO WITH Arraylist

    // Create a couple ArrayList objects and populate them
    // with some delicious fruits.
    ArrayList<String> firstList = new ArrayList<String>() {/**
         * 
         */
        private static final long serialVersionUID = 1L;

    {
        add("apple");
        add("orange");
        add("pea");
    }};

    ArrayList<String> secondList = new ArrayList<String>() {

    /**
         * 
         */
        private static final long serialVersionUID = 1L;

    {
        add("apple");
        add("orange");
        add("banana");
        add("strawberry");
    }};

    // Show the "before" lists
    System.out.println("First List: " + firstList);
    System.out.println("Second List: " + secondList);

    // Remove all elements in firstList from secondList
    secondList.removeAll(firstList);

    // Show the "after" list
    System.out.println("Result: " + secondList);

SELECT * 
FROM 
    PersonAddress a, 
    Person b,
    PersonAdmin c
WHERE a.addressid LIKE '97%' 
    AND b.lastname LIKE 'test%'
    AND b.genderid IS NOT NULL
    AND a.partyid = c.partyid 
    AND b.partyid = c.partyid;

If you sometimes use substitution variables you might not want to turn define off. In these cases you could convert the ampersand from its numeric equivalent as in || Chr(38) || or append it as a single character as in || '&' ||.

See Angular 2: Focus on newly added input element for how to set the focus.

For "on load" use the ngAfterViewInit() lifecycle callback.

If you are using JSR 374: Java API for JSON Processing ( javax json ) This seems to do the trick:

    JsonObjectBuilder job = Json.createObjectBuilder((Map<String, Object>) obj);
    JsonObject jsonObject = job.build();

Evaluating "1,2,3" results in (1, 2, 3), a tuple. As you've discovered, tuples are immutable. Convert to a list before processing.

If you have two Location Objects Location loc1 and Location loc2 you do

float distance = loc1.distanceTo(loc2);

If you have longitude and latitude values you use the static distanceBetween() function

    float[] results = new float[1];
    Location.distanceBetween(startLatitude, startLongitude,
    endLatitude, endLongitude, results);
    float distance = results[0];

Per the documentation you posted, and this blog post - there's no difference when declaring the primitive between an unsigned int/long and a signed one. The "new support" is the addition of the static methods in the Integer and Long classes, e.g. Integer.divideUnsigned. If you're not using those methods, your "unsigned" long above 2^63-1 is just a plain old long with a negative value.

From a quick skim, it doesn't look like there's a way to declare integer constants in the range outside of +/- 2^31-1, or +/- 2^63-1 for longs. You would have to manually compute the negative value corresponding to your out-of-range positive value.

Aaa.h

class Aaa {

protected:

    static Aaa *defaultAaa;

};

Aaa.cpp

// You must define an actual variable in your program for the static members of the classes

static Aaa *Aaa::defaultAaa;

What type of LayoutManager are you using for the panel you're adding the JTextField to?

Different layout managers approach sizing elements on them in different ways, some respect SetPreferredSize(), while others will scale the compoenents to fit their container.

See: http://docs.oracle.com/javase/tutorial/uiswing/layout/visual.html

ps. this has nothing to do with eclipse, its java.

So are you trying to grep through older versions of the code looking to see where something last exists?

If I were doing this, I would probably use git bisect. Using bisect, you can specify a known good version, a known bad version, and a simple script that does a check to see if the version is good or bad (in this case a grep to see if the code you are looking for is present). Running this will find when the code was removed.

You can do this with map()

var arrOfObj = [{_x000D_
  name: 'eve'_x000D_
}, {_x000D_
  name: 'john'_x000D_
}, {_x000D_
  name: 'jane'_x000D_
}];_x000D_
_x000D_
var result = arrOfObj.map(function(o) {_x000D_
  o.isActive = true;_x000D_
  return o;_x000D_
})_x000D_
_x000D_
console.log(result)

If you want to keep original array you can clone objects with Object.assign()

var arrOfObj = [{_x000D_
  name: 'eve'_x000D_
}, {_x000D_
  name: 'john'_x000D_
}, {_x000D_
  name: 'jane'_x000D_
}];_x000D_
_x000D_
var result = arrOfObj.map(function(el) {_x000D_
  var o = Object.assign({}, el);_x000D_
  o.isActive = true;_x000D_
  return o;_x000D_
})_x000D_
_x000D_
console.log(arrOfObj);_x000D_
console.log(result);

I think this is the "set it and forget it" solution:

options(repos='http://cran.rstudio.com/')

Note that this isn't https. I was on a Linux machine, ssh'ing in. If I used https, it didn't work.

I had dialog showing function:

void showDialog(){
    new AlertDialog.Builder(MyActivity.this)
    ...
    .show();
}

I was getting this error and i just had to check isFinishing() before calling this dialog showing function.

if(!isFinishing())
    showDialog();

Another possibility is to use separate lines to set up Make variables when a rule fires.

For example, here is a makefile with two rules. If a rule fires, it creates a temp dir and sets TMP to the temp dir name.

PHONY = ruleA ruleB display

all: ruleA

ruleA: TMP = $(shell mktemp -d testruleA_XXXX)
ruleA: display

ruleB: TMP = $(shell mktemp -d testruleB_XXXX)
ruleB: display

display:
    echo ${TMP}

Running the code produces the expected result:

$ ls
Makefile
$ make ruleB
echo testruleB_Y4Ow
testruleB_Y4Ow
$ ls
Makefile  testruleB_Y4Ow

People often sort stacks of documents using a recursive method. For example, imagine you are sorting 100 documents with names on them. First place documents into piles by the first letter, then sort each pile.

Looking up words in the dictionary is often performed by a binary-search-like technique, which is recursive.

In organizations, bosses often give commands to department heads, who in turn give commands to managers, and so on.

MD5 also benefits from SSE2 usage, check out BarsWF and then tell me that it doesn't. All it takes is a little assembler knowledge and you can craft your own MD5 SSE2 routine(s). For large amounts of throughput however, there is a tradeoff of the speed during hashing as opposed to the time spent rearranging the input data to be compatible with the SIMD instructions used.

The quick possible answer: When you first successfully clone an empty git repository, the origin has no master branch. So the first time you have a commit to push you must do:

git push origin master

Which will create this new master branch for you. Little things like this are very confusing with git.

If this didn't fix your issue then it's probably a gitolite-related issue:

Your conf file looks strange. There should have been an example conf file that came with your gitolite. Mine looks like this:

repo    phonegap                                                                                                                                                                           
    RW+     =   myusername otherusername                                                                                                                                               

repo    gitolite-admin                                                                                                                                                                         
    RW+     =   myusername                                                                                                                                                               

Please make sure you're setting your conf file correctly.

Gitolite actually replaces the gitolite user's account with a modified shell that doesn't accept interactive terminal sessions. You can see if gitolite is working by trying to ssh into your box using the gitolite user account. If it knows who you are it will say something like "Hi XYZ, you have access to the following repositories: X, Y, Z" and then close the connection. If it doesn't know you, it will just close the connection.

Lastly, after your first git push failed on your local machine you should never resort to creating the repo manually on the server. We need to know why your git push failed initially. You can cause yourself and gitolite more confusion when you don't use gitolite exclusively once you've set it up.

Just translate Jojodmo code to Swift:

//If you have more than one in-app purchase, you can define both of
//of them here. So, for example, you could define both kRemoveAdsProductIdentifier

I know it's an old thread, but I landed here several times via Google and think no given answer is really satisfying yet. Try using one of the following functions:

EDIT: As I'm getting some likes on this old thread, I wanna share an updated solution as well (basically putting my two previous functions together and automatically deciding whether it's a bar or hbar plot):

def label_bars(ax, bars, text_format, **kwargs):
    """
    Attaches a label on every bar of a regular or horizontal bar chart
    """
    ys = [bar.get_y() for bar in bars]
    y_is_constant = all(y == ys[0] for y in ys)  # -> regular bar chart, since all all bars start on the same y level (0)

    if y_is_constant:
        _label_bar(ax, bars, text_format, **kwargs)
    else:
        _label_barh(ax, bars, text_format, **kwargs)


def _label_bar(ax, bars, text_format, **kwargs):
    """
    Attach a text label to each bar displaying its y value
    """
    max_y_value = ax.get_ylim()[1]
    inside_distance = max_y_value * 0.05
    outside_distance = max_y_value * 0.01

    for bar in bars:
        text = text_format.format(bar.get_height())
        text_x = bar.get_x() + bar.get_width() / 2

        is_inside = bar.get_height() >= max_y_value * 0.15
        if is_inside:
            color = "white"
            text_y = bar.get_height() - inside_distance
        else:
            color = "black"
            text_y = bar.get_height() + outside_distance

        ax.text(text_x, text_y, text, ha='center', va='bottom', color=color, **kwargs)


def _label_barh(ax, bars, text_format, **kwargs):
    """
    Attach a text label to each bar displaying its y value
    Note: label always outside. otherwise it's too hard to control as numbers can be very long
    """
    max_x_value = ax.get_xlim()[1]
    distance = max_x_value * 0.0025

    for bar in bars:
        text = text_format.format(bar.get_width())

        text_x = bar.get_width() + distance
        text_y = bar.get_y() + bar.get_height() / 2

        ax.text(text_x, text_y, text, va='center', **kwargs)

Now you can use them for regular bar plots:

fig, ax = plt.subplots((5, 5))
bars = ax.bar(x_pos, values, width=0.5, align="center")
value_format = "{:.1%}"  # displaying values as percentage with one fractional digit
label_bars(ax, bars, value_format)

or for horizontal bar plots:

fig, ax = plt.subplots((5, 5))
horizontal_bars = ax.barh(y_pos, values, width=0.5, align="center")
value_format = "{:.1%}"  # displaying values as percentage with one fractional digit
label_bars(ax, horizontal_bars, value_format)

If you are using PHP7.1 ( try php -version to find your PHP version)

sudo apt-get install php7.1-curl

then restart apache

sudo service apache2 restart

You guys are making this WAY too hard on yourselves. It's this easy:

void OnFormClosing(object sender, FormClosingEventArgs e)
{
    foreach(Delegate d in FindClicked.GetInvocationList())
    {
        FindClicked -= (FindClickedHandler)d;
    }
}

There's a RemoveDuplicates method that you could use:

Sub DeleteRows()

    With ActiveSheet
        Set Rng = Range("A1", Range("B1").End(xlDown))
        Rng.RemoveDuplicates Columns:=Array(1, 2), Header:=xlYes
    End With

End Sub

I am using Bootstrap & HTML5. I wanted to override the look of the toggle button.

.navbar-toggle{
    background-color: #5DADB0;
    color: #F3DBAA;
    border:none;        
}

.navbar-toggle.but-menu:link {
    color: #F00;
    background-color: #CF995F;
}

.navbar-toggle.but-menu:visited {
    color: #FFF;
    background-color: #CF995F;
}
.navbar-toggle.but-menu:hover {
    color: #FFF0C9;
    background-color: #CF995F;
}
.navbar-toggle.but-menu:active {
    color: #FFF;
    background-color: #CF995F;
}
.navbar-toggle.but-menu:focus {
    color: #FFF;
    background-color: #CF995F;
}

Vertical-align is one of the most misused css styles. It doesn't work how you might expect on elements that are not td's or css "display: table-cell".

This is a very good post on the matter. http://phrogz.net/CSS/vertical-align/index.html

The most common methods to acheive what you're looking for are:

• padding top/bottom
• position absolute
• line-height

Adding java.util.list will resolve your problem because List interface which you are trying to use is part of java.util.list package.

google.com is not responding to HTTP HEAD requests, which is why you are seeing a hang for the first command.

It does respond to GET requests, which is why the third command works.

As for the second, curl just prints the headers from a standard request.

Place the \n in double quotes:

explode("\n", $_POST['skuList']);

In single quotes, if I'm not mistaken, this is treated as \ and n separately.

You can use the reset() method:

$('#myform')[0].reset();

or without jQuery:

document.getElementById('myform').reset();

where myform is the id of the form containing the elements you want to be cleared.

You could also use the :input selector if the fields are not inside a form:

$(':input').val('');

If you only need a current value and above options don't work, you can use it this way.

$('#input').on('change', () => {
  const current = document.getElementById('input').value;
}

I have come to similar question when I execute the bulk insert in SSMS it's working but it failed and returned with "Operation system failure code 5" when converting the task into SQL Server Agent.

After browsing lots of solutions posted previously, this way solved my problem by granting the NT SERVER/SQLSERVERAGENT with the 'full control" access right to the source folder. Hope it would bring some light to these people who are still struggling with the error message.

Here is a solution that:

1. Drops constraints (thanks to this post)
2. Iterates through INFORMATION_SCHEMA.TABLES for a particular database
3. SELECTS tables based on some search criteria
4. Deletes all the data from those tables
5. Re-adds constraints
6. Allows for ignoring of certain tables such as sysdiagrams and __RefactorLog

I initially tried EXECUTE sp_MSforeachtable 'TRUNCATE TABLE ?', but that deleted my diagrams.

USE <DB name>;
GO

-- Disable all constraints in the database
EXEC sp_msforeachtable "ALTER TABLE ? NOCHECK CONSTRAINT all"

declare @catalog nvarchar(250);
declare @schema nvarchar(250);
declare @tbl nvarchar(250);
DECLARE i CURSOR LOCAL FAST_FORWARD FOR select
                                        TABLE_CATALOG,
                                        TABLE_SCHEMA,
                                        TABLE_NAME
                                        from INFORMATION_SCHEMA.TABLES
                                        where
                                        TABLE_TYPE = 'BASE TABLE'
                                        AND TABLE_NAME != 'sysdiagrams'
                                        AND TABLE_NAME != '__RefactorLog'

OPEN i;
FETCH NEXT FROM i INTO @catalog, @schema, @tbl;
WHILE @@FETCH_STATUS = 0
    BEGIN
        DECLARE @sql NVARCHAR(MAX) = N'DELETE FROM [' + @catalog + '].[' + @schema + '].[' + @tbl + '];'
        /* Make sure these are the commands you want to execute before executing */
        PRINT 'Executing statement: ' + @sql
        -- EXECUTE sp_executesql @sql
        FETCH NEXT FROM i INTO @catalog, @schema, @tbl;
    END
CLOSE i;
DEALLOCATE i;

-- Re-enable all constraints again
EXEC sp_msforeachtable "ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all"

There are various causes of segmentation faults, but fundamentally, you are accessing memory incorrectly. This could be caused by dereferencing a null pointer, or by trying to modify readonly memory, or by using a pointer to somewhere that is not mapped into the memory space of your process (that probably means you are trying to use a number as a pointer, or you incremented a pointer too far). On some machines, it is possible for a misaligned access via a pointer to cause the problem too - if you have an odd address and try to read an even number of bytes from it, for example (that can generate SIGBUS, instead).

You probably want to assign the lastname you are reading out here

lastname = sheet.cell(row=r, column=3).value

to something; currently the program just forgets it

you could do that two lines after, like so

unpaidMembers[name] = lastname, email

your program will still crash at the same place, because .items() still won't give you 3-tuples but rather something that has this structure: (name, (lastname, email))

good news is, python can handle this

for name, (lastname, email) in unpaidMembers.items():

etc.

This is a sample simplelogger.properties which you can place on the classpath (uncomment the properties you wish to use):

# SLF4J's SimpleLogger configuration file
# Simple implementation of Logger that sends all enabled log messages, for all defined loggers, to System.err.

# Logging detail level for a SimpleLogger instance named "xxxxx".

# If not specified, the default logging detail level is used.
#org.slf4j.simpleLogger.log.xxxxx=

# Set to true if you want the current date and time to be included in output messages.

There are many different versions of mail around. When you go beyond mail -s subject to1@address1 to2@address2

• With some mailx implementations, e.g. from mailutils on Ubuntu or Debian's bsd-mailx, it's easy, because there's an option for that.

  mailx -a 'Content-Type: text/html' -s "Subject" to@address <test.html
  

• With the Heirloom mailx, there's no convenient way. One possibility to insert arbitrary headers is to set editheaders=1 and use an external editor (which can be a script).

  ## Prepare a temporary script that will serve as an editor.
  
  ## This script will be passed to ed.
  temp_script=$(mktemp)
  cat <<'EOF' >>"$temp_script"
  1a
  Content-Type: text/html
  .
  $r test.html
  w
  q
  EOF
  ## Call mailx, and tell it to invoke the editor script
  EDITOR="ed -s $temp_script" heirloom-mailx -S editheaders=1 -s "Subject" to@address <<EOF
  ~e
  .
  EOF
  rm -f "$temp_script"
  

• With a general POSIX mailx, I don't know how to get at headers.

If you're going to use any mail or mailx, keep in mind that

• This isn't portable even within a given Linux distribution. For example, both Ubuntu and Debian have several alternatives for mail and mailx.

• When composing a message, mail and mailx treats lines beginning with ~ as commands. If you pipe text into mail, you need to arrange for this text not to contain lines beginning with ~.

If you're going to install software anyway, you might as well install something more predictable than mail/Mail/mailx. For example, mutt. With Mutt, you can supply most headers in the input with the -H option, but not Content-Type, which needs to be set via a mutt option.

mutt -e 'set content_type=text/html' -s 'hello' 'to@address' <test.html

Or you can invoke sendmail directly. There are several versions of sendmail out there, but they all support sendmail -t to send a mail in the simplest fashion, reading the list of recipients from the mail. (I think they don't all support Bcc:.) On most systems, sendmail isn't in the usual $PATH, it's in /usr/sbin or /usr/lib.

cat <<'EOF' - test.html | /usr/sbin/sendmail -t
To: to@address
Subject: hello
Content-Type: text/html

EOF

For end of line use:

git diff --ignore-space-at-eol

Instead of what are you using currently:

git diff -w (--ignore-all-space)

For start of line... you are out of luck if you want a built in solution.

However, if you don't mind getting your hands dirty there's a rather old patch floating out there somewhere that adds support for "--ignore-space-at-sol".

The most common way I have seen to encode this is with a character class whose members form a partition of the set of all possible characters.

Usually people write that as [\s\S] (whitespace or non-whitespace), though [\w\W], [\d\D], etc. would all work.

Try this:

rows = tabDelimitedTable.split("[\\r\\n]+");

This should work regardless of what line delimiters are in the input, and will ignore blank lines.

I met a similar problem. The solution is to use git log to look up which version of the local commit is different from the remote. (E.g. the version is 3c74a11530697214cbcc4b7b98bf7a65952a34ec).

Then use git reset --hard 3c74a11530697214cbcc4b7b98bf7a65952a34ec to revert the change.

I've found my optimal blocksize to be 8 MB (equal to disk cache?) I needed to wipe (some say: wash) the empty space on a disk before creating a compressed image of it. I used:

cd /media/DiskToWash/
dd if=/dev/zero of=zero bs=8M; rm zero

I experimented with values from 4K to 100M.

After letting dd to run for a while I killed it (Ctlr+C) and read the output:

36+0 records in
36+0 records out
301989888 bytes (302 MB) copied, 15.8341 s, 19.1 MB/s

As dd displays the input/output rate (19.1MB/s in this case) it's easy to see if the value you've picked is performing better than the previous one or worse.

My scores:

bs=   I/O rate
---------------
4K    13.5 MB/s
64K   18.3 MB/s
8M    19.1 MB/s <--- winner!
10M   19.0 MB/s
20M   18.6 MB/s
100M  18.6 MB/s   

Note: To check what your disk cache/buffer size is, you can use sudo hdparm -i /dev/sda

I came across this question, and I will add my solution for those who may be looking for something similar. My approach was just to make a random file name from ascii characters. It will be unique with a good probability.

from random import sample
from string import digits, ascii_uppercase, ascii_lowercase
from tempfile import gettempdir
from os import path

def rand_fname(suffix, length=8):
    chars = ascii_lowercase + ascii_uppercase + digits

    fname = path.join(gettempdir(), 'tmp-'
                + ''.join(sample(chars, length)) + suffix)

ihave followed the instruction of heroku logs img https://devcenter.heroku.com/articles/buildpacks#detection-failure ( use cmd: heroku logs -> show your error) then do the cmd: "heroku buildpacks:clear". finally, it worked for me!

URI => http://en.wikipedia.org/wiki/Uniform_Resource_Identifier

URL's are a subset of URI's (which also contain URNs).

Basically, a URI is a general identifier, where a URL specifies a location and a URN specifies a name.

If you are using Resharper make sure it does not add the wrong header for you, very common cases with ReSharper are:

• #include <consoleapi2.h
  
• #include <apiquery2.h>
• #include <fileapi.h>

UPDATE:
Another suggestion is to check if you are including a "partial Windows.h", what I mean is that if you include for example winbase.h or minwindef.h you may end up with that error, add "the big" Windows.h instead. There are also some less obvious cases that I went through, the most notable was when I only included synchapi.h, the docs clearly state that is the header to be included for some functions like AcquireSRWLockShared but it triggered the No target architecture, the fix was to remove the synchapi.h and include "the big" Windows.h.

The Windows.h is huge, it defines macros(many of them remove the No target arch error) and includes many other headers. In summary, always check if you are including some header that could be replaced by Windows.h because it is not unusual to include a header that relies on some constants that are defined by Windows.h, so if you fail to include this header your compilation may fail.

To directly answer your question if you want to return a view that belongs to another controller you simply have to specify the name of the view and its folder name.

public class CommentsController : Controller
{
    public ActionResult Index()
    { 
        return View("../Articles/Index", model );
    }
}

and

public class ArticlesController : Controller
{
    public ActionResult Index()
    { 
        return View();
    }
}

Also, you're talking about using a read and write method from one controller in another. I think you should directly access those methods through a model rather than calling into another controller as the other controller probably returns html.

Here is an option. It works by using making an INDIRECT(ADDRESS(...)) from the ROW and COLUMN of the start cell, A1, down to the initial row + the number of rows held in B1.

SUM(INDIRECT(ADDRESS(ROW(A1),COLUMN(A1))):INDIRECT(ADDRESS(ROW(A1)+B1,COLUMN(A1))))

A1: is the start of data in a the "A" column

B1: is the number of rows to sum

With ps or similar tools you will only get the amount of memory pages allocated by that process. This number is correct, but:

• does not reflect the actual amount of memory used by the application, only the amount of memory reserved for it

• can be misleading if pages are shared, for example by several threads or by using dynamically linked libraries

If you really want to know what amount of memory your application actually uses, you need to run it within a profiler. For example, Valgrind can give you insights about the amount of memory used, and, more importantly, about possible memory leaks in your program. The heap profiler tool of Valgrind is called 'massif':

Massif is a heap profiler. It performs detailed heap profiling by taking regular snapshots of a program's heap. It produces a graph showing heap usage over time, including information about which parts of the program are responsible for the most memory allocations. The graph is supplemented by a text or HTML file that includes more information for determining where the most memory is being allocated. Massif runs programs about 20x slower than normal.

As explained in the Valgrind documentation, you need to run the program through Valgrind:

valgrind --tool=massif <executable> <arguments>

Massif writes a dump of memory usage snapshots (e.g. massif.out.12345). These provide, (1) a timeline of memory usage, (2) for each snapshot, a record of where in your program memory was allocated. A great graphical tool for analyzing these files is massif-visualizer. But I found ms_print, a simple text-based tool shipped with Valgrind, to be of great help already.

To find memory leaks, use the (default) memcheck tool of valgrind.

When I tried yorammi's solution I was taken to Slack, but not the channel I specified.

I had better luck with:

https://<organization>.slack.com/messages/#<channel>/

and

https://<organization>.slack.com/messages/<channel>/details/

Although, they were both still displayed in a browser window and not the app.

One more simple variant -

$ while read line
  do
      set $line          # assigns words in line to positional parameters
      echo "$3 $5"
  done < file

If you're using OpenResty then it provides for in-built millisecond time accuracy through the use of its ngx.now() function. Although if you want fine grained millisecond accuracy then you may need to call ngx.update_time() first. Or if you want to go one step further...

If you are using luajit enabled environment, such as OpenResty, then you can also use ffi to access C based time functions such as gettimeofday() e.g: (Note: The pcall check for the existence of struct timeval is only necessary if you're running it repeatedly e.g. via content_by_lua_file in OpenResty - without it you run into errors such as attempt to redefine 'timeval')

if pcall(ffi.typeof, "struct timeval") then
        -- check if already defined.
else
        -- undefined! let's define it!
        ffi.cdef[[
           typedef struct timeval {
                long tv_sec;
                long tv_usec;
           } timeval;

        int gettimeofday(struct timeval* t, void* tzp);
]]
end
local gettimeofday_struct = ffi.new("struct timeval")
local function gettimeofday()
        ffi.C.gettimeofday(gettimeofday_struct, nil)
        return tonumber(gettimeofday_struct.tv_sec) * 1000000 + tonumber(gettimeofday_struct.tv_usec)
end

Then the new lua gettimeofday() function can be called from lua to provide the clock time to microsecond level accuracy.

Indeed, one could take a similar approaching using clock_gettime() to obtain nanosecond accuracy.

Just for the record..

It is actually not a solution to your code, but I had the same error message when incorrectly accessing the method of a class instance pointed to by myPointerToClass, e.g.

MyClass* myPointerToClass = new MyClass();
myPointerToClass.aMethodOfThatClass();

where

myPointerToClass->aMethodOfThatClass();

would obviously be correct.

To get the current time in UTC in Python 3.2+:

>>> from datetime import datetime, timezone
>>> datetime.now(timezone.utc).isoformat()
'2015-01-27T05:57:31.399861+00:00'

To get local time in Python 3.3+:

>>> from datetime import datetime, timezone
>>> datetime.now(timezone.utc).astimezone().isoformat()
'2015-01-27T06:59:17.125448+01:00'

Explanation: datetime.now(timezone.utc) produces a timezone aware datetime object in UTC time. astimezone() then changes the timezone of the datetime object, to the system's locale timezone if called with no arguments. Timezone aware datetime objects then produce the correct ISO format automatically.

You need to explicitly ask for the content type.

Add this line:

 request.ContentType = "application/json; charset=utf-8";
