It's possible that your WCF service is returning HTML. In this case, you'll want to set up a binding on the service side to return XML instead. However, this is unlikely: if it is the case, let me know and I'll make an edit with more details.

The more likely reason is that your service is throwing an error, which is returning an HTML error page. You can take a look at this blog post if you want details.

tl;dr: There are a few possible configurations for error pages. If you're hosting on IIS, you'll want to remove the <httpErrors> section from the WCF service's web.config file. If not, please provide details of your service hosting scenario and I can come up with an edit to match them.

EDIT:

Having seen your edit, you can see the full error being returned. Apache can't tell which service you want to call, and is throwing an error for that reason. The service will work fine once you have the correct endpoint - you're pointed at the wrong location. I unfortunately can't tell from the information available what the right location is, but either your action (currently null!) or the URL is incorrect.

one-liner bash script to help facility Chris's answer above, as I had painted myself in a corner as well using Vundle updates to my .vim scripts. DEST is the path to the directory containing your submodules. Do this after doing git rm -r $DEST

DEST='path'; for file in `ls ${DEST}`; do git submodule add `grep url ${DEST}/${file}/.git/config|awk -F= '{print $2}'` ${DEST}/${file}; done

cheers

Use:

SELECT * 
FROM [Janus999DB].[dbo].[tblCustomerPlay] 
WHERE DatePlayed <  GetDate() 
AND DatePlayed > dateadd(minute, -30, GetDate())

SELECT ID,LastName 
From TABLE_NAME 
GROUP BY FirstName 
HAVING COUNT(*) >=1

here is my implementation in modern browser (without dependency):

transpose = m => m[0].map((x,i) => m.map(x => x[i]))

Open DDMS than in DATA>DATA>"Select your package like com.example.foo"> than select your database folder than pull that data in eclipse you can see the pull an push icon on top right side ...

Add reference .dll file to project. Right, Click on Project reference folder --> click on Add Reference -->.Net tab you will find System.Drawing --> click on ok this will add a reference to System.Drawing

If I understand your problem correctly, you are calling a method instead of passing it as a parameter. Try the following:

myTimer.Elapsed += PlayMusicEvent;

where

public void PlayMusicEvent(object sender, ElapsedEventArgs e)
{
    music.player.Stop();
    System.Timers.Timer myTimer = (System.Timers.Timer)sender;
    myTimer.Stop();
}

But you need to think about where to store your note.

Lately I have been tending to prefer m_ prefix instead of having no prefix at all, the reasons isn't so much that its important to flag member variables, but that it avoids ambiguity, say you have code like:

void set_foo(int foo) { foo = foo; }

That of cause doesn't work, only one foo allowed. So your options are:

• this->foo = foo;

  I don't like it, as it causes parameter shadowing, you no longer can use g++ -Wshadow warnings, its also longer to type then m_. You also still run into naming conflicts between variables and functions when you have a int foo; and a int foo();.

• foo = foo_; or foo = arg_foo;

  Been using that for a while, but it makes the argument lists ugly, documentation shouldn't have do deal with name disambiguity in the implementation. Naming conflicts between variables and functions also exist here.

• m_foo = foo;

  API Documentation stays clean, you don't get ambiguity between member functions and variables and its shorter to type then this->. Only disadvantage is that it makes POD structures ugly, but as POD structures don't suffer from the name ambiguity in the first place, one doesn't need to use it with them. Having a unique prefix also makes a few search&replace operations easier.

• foo_ = foo;

  Most of the advantages of m_ apply, but I reject it for aesthetic reasons, a trailing or leading underscore just makes the variable look incomplete and unbalanced. m_ just looks better. Using m_ is also more extendable, as you can use g_ for globals and s_ for statics.

PS: The reason why you don't see m_ in Python or Ruby is because both languages enforce the their own prefix, Ruby uses @ for member variables and Python requires self..

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);

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.width = 72 * 8.5;

            pdf.fromHTML(document.body);

            pdf.save('test.pdf');

Visual Studio for Windows Apps is meant to be used to build Windows Store Apps using HTML & Javascript or WinRT and XAML. These can also run on the Windows tablet that run Windows RT.

Visual Studio for Windows Desktop is meant to build applications using Windows Forms or Windows Presentation Foundation, these can run on Windows 8.1 on a normal desktop or on a tablet device like the Surface Pro in desktop mode (like a classic windows application).

Just adding another solution that works for me.. You can simply append it in the marker options:

var marker = new google.maps.Marker({
    map: map, 
    position: position,

    // Custom Attributes / Data / Key-Values
    store_id: id,
    store_address: address,
    store_type: type
});

And then retrieve them with:

marker.get('store_id');
marker.get('store_address');
marker.get('store_type');

i had a similar problem with the editText, which gained focus since the activity was started. this problem i fixed easily like this:

you add this piece of code into the layout that contains the editText in xml:

    android:id="@+id/linearlayout" 
    android:focusableInTouchMode="true"

dont forget the android:id, without it i've got an error.

the other problem i had with the editText is that once it gain the first focus, the focus never disappeared. this is a piece of my code in java, it has an editText and a button that captures the text in the editText:

    editText=(EditText) findViewById(R.id.et1);
    tvhome= (TextView)findViewById(R.id.tv_home);
    etBtn= (Button) findViewById(R.id.btn_homeadd);
    etBtn.setOnClickListener(new View.OnClickListener() 
    {   
        @Override
        public void onClick(View v)
        {
            tvhome.setText( editText.getText().toString() );

            //** this code is for hiding the keyboard after pressing the button
            View view = Settings.this.getCurrentFocus();
            if (view != null) 
            {  
                InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
            }
            //**

            editText.getText().clear();//clears the text
            editText.setFocusable(false);//disables the focus of the editText 
            Log.i("onCreate().Button.onClickListener()", "et.isfocused= "+editText.isFocused());
        }
    });
    editText.setOnClickListener(new View.OnClickListener() 
    {
        @Override
        public void onClick(View v) 
        {
            if(v.getId() == R.id.et1)
            {
                v.setFocusableInTouchMode(true);// when the editText is clicked it will gain focus again

                //** this code is for enabling the keyboard at the first click on the editText
                if(v.isFocused())//the code is optional, because at the second click the keyboard shows by itself
                {
                    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.showSoftInput(v, InputMethodManager.SHOW_IMPLICIT);
                }
                //**

                Log.i("onCreate().EditText.onClickListener()", "et.isfocused= "+v.isFocused());
            }
            else
                Log.i("onCreate().EditText.onClickListener()", "the listener did'nt consume the event");
        }
    });

hope it will help to some of you!

Turns out it needs to be specified via escaped unicode. This question is related and contains the answer.

The solution:

h2:after {
    content: "\00a0";
}

Please use

.FirstOrDefault()

because if in the first row of the result there is no info this instruction goes to the default info.

You can also replace without a regular expression.

while(str.indexOf('  ')!=-1)str.replace('  ',' ');

You can also use $.parseJSON(data) that will explicit convert a string thats come from a PHP script to a real JSON array.

var max = db.Users.DefaultIfEmpty().Max(r => r == null ? 0 : r.ModelID);

when there are no records in db it would return 0 with no exception.

Official Definition

From the reference docs of Comparable.compareTo(T):

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

The implementor must ensure sgn(x.compareTo(y)) == -sgn(y.compareTo(x)) for all x and y. (This implies that x.compareTo(y) must throw an exception iff y.compareTo(x) throws an exception.)

The implementor must also ensure that the relation is transitive: (x.compareTo(y)>0 && y.compareTo(z)>0) implies x.compareTo(z)>0.

Finally, the implementor must ensure that x.compareTo(y)==0 implies that sgn(x.compareTo(z)) == sgn(y.compareTo(z)), for all z.

It is strongly recommended, but not strictly required that (x.compareTo(y)==0) == (x.equals(y)). Generally speaking, any class that implements the Comparable interface and violates this condition should clearly indicate this fact. The recommended language is "Note: this class has a natural ordering that is inconsistent with equals."

In the foregoing description, the notation sgn(expression) designates the mathematical signum function, which is defined to return one of -1, 0, or 1 according to whether the value of expression is negative, zero or positive.

My Version

In short:

this.compareTo(that)

returns

• a negative int if this < that
• 0 if this == that
• a positive int if this > that

where the implementation of this method determines the actual semantics of < > and == (I don't mean == in the sense of java's object identity operator)

Examples

"abc".compareTo("def")

will yield something smaller than 0 as abc is alphabetically before def.

Integer.valueOf(2).compareTo(Integer.valueOf(1))

will yield something larger than 0 because 2 is larger than 1.

Some additional points

Note: It is good practice for a class that implements Comparable to declare the semantics of it's compareTo() method in the javadocs.

Note: you should read at least one of the following:

• the Object Ordering section of the Collection Trail in the Sun Java Tutorial
• Effective Java by Joshua Bloch, especially item 12: Consider implementing Comparable
• Java Generics and Collections by Maurice Naftalin, Philip Wadler, chapter 3.1: Comparable

Warning: you should never rely on the return values of compareTo being -1, 0 and 1. You should always test for x < 0, x == 0, x > 0, respectively.

parse_cols is deprecated, use usecols instead

that is:

df = pd.read_excel(file_loc, index_col=None, na_values=['NA'], usecols = "A,C:AA")

Use a packet analyzer to intercept the packets to/from somewhere.com. Studying those packets should tell you what is going on.

Time-outs or connections refused could mean that the remote host is too busy.

I found a solution to this here. Using the OP's example you basically run

stdbuf -oL /homedir/MyScript &> some_log.log

and then the buffer gets flushed after each line of output. I often combine this with nohup to run long jobs on a remote machine.

stdbuf -oL nohup /homedir/MyScript &> some_log.log

This way your process doesn't get cancelled when you log out.

In the Windows Command Prompt the ^ is used to escape the next character on the command line. (Like \ is used in strings.) Characters that need to be used in the command line as they are should have a ^ prefixed to them, hence that's why it works for the newline.

For reference the characters that need escaping (if specified as command arguments and not within quotes) are: &|()

So the equivalent of your linux example would be (the More? being a prompt):

C:\> dir ^
More? C:\Windows

This is how I do with a batch file to delete all BIN and OBJ folders recursively.

• Create an empty file and name it DeleteBinObjFolders.bat
• Copy-paste code the below code into the DeleteBinObjFolders.bat
• Move the DeleteBinObjFolders.bat file in the same folder with your solution (*.sln) file.

@echo off
@echo Deleting all BIN and OBJ folders...
for /d /r . %%d in (bin,obj) do @if exist "%%d" rd /s/q "%%d"
@echo BIN and OBJ folders successfully deleted :) Close the window.
pause > nul

This is one solution. If you want to make it more generic, you can use the StringUtils library.

String value = "{first_name = naresh,last_name = kumar,gender = male}";
value = value.substring(1, value.length()-1);           //remove curly brackets
String[] keyValuePairs = value.split(",");              //split the string to creat key-value pairs
Map<String,String> map = new HashMap<>();               

for(String pair : keyValuePairs)                        //iterate over the pairs
{
    String[] entry = pair.split("=");                   //split the pairs to get key and value 
    map.put(entry[0].trim(), entry[1].trim());          //add them to the hashmap and trim whitespaces
}

For example you can switch

 value = value.substring(1, value.length()-1);

to

 value = StringUtils.substringBetween(value, "{", "}");

if you are using StringUtils which is contained in apache.commons.lang package.

just use this,

utf8_encode($string);

you've to replace your $arr with $string.

I think it will work...try this.

If you're talking about PL/SQL, you should put it in an anonymous block.

DECLARE
    v_text VARCHAR2(10); -- declare
BEGIN
    v_text := 'Hello';  --assign
    dbms_output.Put_line(v_text); --display
END; 

I assume you mean the size of the bullet at the start of each list item. If that's the case, you can use an image instead of it:

list-style-image:url('bigger.gif');
list-style-type:none;

If you meant the actual size of the li element, then you can change that as normal with width and height.

Try this:

$('div.btn-group ul.dropdown-menu li a').click(function (e) {
    var $div = $(this).parent().parent().parent(); 
    var $btn = $div.find('button');
    $btn.html($(this).text() + ' <span class="caret"></span>');
    $div.removeClass('open');
    e.preventDefault();
    return false;
});

Use this

string[] str = new string[] {"Foo", "Bar"};

myComboBox.ItemsSource = str;
myComboBox.SelectedIndex = 0;

OR

foreach (string s in str)
    myComboBox.Items.Add(s);

myComboBox.SelectedIndex = 0;      

//first: Create a class as your view model

public class EventViewModel 
{
 public int Id{get;set}
 public string Property1{get;set;}
 public string Property2{get;set;}
}
//then from your method
[HttpGet]
public async Task<ActionResult> GetEvent()
{
 var events = await db.Event.Find(x => x.ID != 0);
 List<EventViewModel> model = events.Select(event => new EventViewModel(){
 Id = event.Id,
 Property1 = event.Property1,
 Property1 = event.Property2
}).ToList();
 return Json(new{ data = model }, JsonRequestBehavior.AllowGet);
}

In my case I had to do this

npm install @types/jquery --save-dev // install jquery type as dev dependency so TS can compile properly
npm install jquery --save // save jquery as a dependency

Then in the script file A.ts

import * as $ from "jquery";
... jquery code ...

Virtual destructors are useful when you might potentially delete an instance of a derived class through a pointer to base class:

class Base 
{
    // some virtual methods
};

class Derived : public Base
{
    ~Derived()
    {
        // Do some important cleanup
    }
};

Here, you'll notice that I didn't declare Base's destructor to be virtual. Now, let's have a look at the following snippet:

Base *b = new Derived();
// use b
delete b; // Here's the problem!

Since Base's destructor is not virtual and b is a Base* pointing to a Derived object, delete b has undefined behaviour:

[In delete b], if the static type of the object to be deleted is different from its dynamic type, the static type shall be a base class of the dynamic type of the object to be deleted and the static type shall have a virtual destructor or the behavior is undefined.

In most implementations, the call to the destructor will be resolved like any non-virtual code, meaning that the destructor of the base class will be called but not the one of the derived class, resulting in a resources leak.

To sum up, always make base classes' destructors virtual when they're meant to be manipulated polymorphically.

If you want to prevent the deletion of an instance through a base class pointer, you can make the base class destructor protected and nonvirtual; by doing so, the compiler won't let you call delete on a base class pointer.

You can learn more about virtuality and virtual base class destructor in this article from Herb Sutter.

If you still get Permission denied errors when you try to run your script in the docker's entrypoint, just try DO NOT use the shell form of the entrypoint:

Instead of: ENTRYPOINT ./bin/watcher write ENTRYPOINT ["./bin/watcher"]:

You need to make sure, when you run command (install npm -g gulp), it will create install gulp on C:\ directory.

that directory should match with whatver npm path variable set in your java path.

just run path from command prompt, and verify this. if not, change your java class path variable wherever you gulp is instaled.

It should work.

My suggestion is also to use a screen recorder, such as SMRecorder. Instead of using the emulator, which is slow - especially for games and things you would want a video of, I recommend using a VirtualBox VM, with Android installed. You can connect the Dalvik debugger to it and debug you app there. If the debugger slows down you app too much, disconnect it to record the video. There are many links out there explaining how to set up the Android VM for debugging. I find it far better than the emulator. Now this does not take care of capturing screens directly on the device, in case you app uses the accelerometer, or the camera that are not available on the PC. For that I would use the android market app mentioned above.

I agree to Ashot and Cwan, but maybe you like to convert an ascii-cipher like '7' into an int like 7?

Then I recoomend:

char seven = '7';
int i = seven - '0'; 

or, maybe you get a warning,

int i = (int) (seven - '0'); 

corrected after comments, thanks.

The error is not refering to myfunction but to start.

Also, know that there is a special case where return await is correct and important : (using try/catch)

Are there performance concerns with `return await`?

The accepted answer is great. This is not answer, but just an illustration of the issue.

I present a viewController like this:

inside vc1:

func showVC2() {
    if let navController = self.navigationController{
        navController.present(vc2, animated: true)
    }
}

inside vc2:

func returnFromVC2() {
    if let navController = self.navigationController {
        navController.popViewController(animated: true)
    }else{
        print("navigationController is nil") <-- I was reaching here!
    }
}

As 'stefandouganhyde' has said: "it is not contained by your UINavigationController or any other"

new solution:

func returnFromVC2() {
    dismiss(animated: true, completion: nil)
}

In my experience the bind_param was fine but I had mistaken the database name so, I changed only the database name in the connection parameter and it worked perfectly.

I had defined root path to indicate the root folder, include path to include folder and base url for the home url of website. This will be used for calling them anywhere they are required.

UPDATE: for rxjs > v5.5

As mentioned in some of the comments and other answers, by default the HttpClient deserializes the content of a response into an object. Some of its methods allow passing a generic type argument in order to duck-type the result. Thats why there is no json() method anymore.

import {throwError} from 'rxjs';
import {catchError, map} from 'rxjs/operators';

export interface Order {
  // Properties
}

interface ResponseOrders {
  results: Order[];
}

@Injectable()
export class FooService {
 ctor(private http: HttpClient){}

 fetch(startIndex: number, limit: number): Observable<Order[]> {
    let params = new HttpParams();
    params = params.set('startIndex',startIndex.toString()).set('limit',limit.toString());
    // base URL should not have ? in it at the en
    return this.http.get<ResponseOrders >(this.baseUrl,{
       params
    }).pipe(
       map(res => res.results || []),
       catchError(error => _throwError(error.message || error))
    );
} 

Notice that you could easily transform the returned Observable to a Promise by simply invoking toPromise().

ORIGINAL ANSWER:

In your case, you can

Assumming that your backend returns something like:

{results: [{},{}]}

in JSON format, where every {} is a serialized object, you would need the following:

// Somewhere in your src folder

export interface Order {
  // Properties
}

import { HttpClient, HttpParams } from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/map';

import { Order } from 'somewhere_in_src';    

@Injectable()
export class FooService {
 ctor(private http: HttpClient){}

 fetch(startIndex: number, limit: number): Observable<Order[]> {
    let params = new HttpParams();
    params = params.set('startIndex',startIndex.toString()).set('limit',limit.toString());
    // base URL should not have ? in it at the en
    return this.http.get(this.baseUrl,{
       params
    })
    .map(res => res.results as Order[] || []); 
   // in case that the property results in the res POJO doesnt exist (res.results returns null) then return empty array ([])
  }
} 

I removed the catch section, as this could be archived through a HTTP interceptor. Check the docs. As example:

https://gist.github.com/jotatoledo/765c7f6d8a755613cafca97e83313b90

And to consume you just need to call it like:

// In some component for example
this.fooService.fetch(...).subscribe(data => ...); // data is Order[]

https://httpbin.org/

It echoes the data used in your request for any of these types:

• https://httpbin.org/anything Returns most of the below.
• https://httpbin.org/ip Returns Origin IP.
• https://httpbin.org/user-agent Returns user-agent.
• https://httpbin.org/headers Returns header dict.
• https://httpbin.org/get Returns GET data.
• https://httpbin.org/post Returns POST data.

I had the same problem. Initially I had setup Eclipse CDT with Cygwing & was working smoothly. One day there happened a problem due to which I had to reset windows. After that when I opened Eclipse I started facing the issue described above. This is how I solved it.

First I searched that in the error the PATH variable value is same as the PATH variable of windows ( just by manual comparison of both two values ). I found that to be same. Now I realized that it is a PATH problem.

Then started looking for Cygwin whether it is there or not? It was there. I located & found that it exists in

C:\cygwin64\bin>
C:\cygwin64\bin>dir ma*
 Volume in drive C is Windows8_OS
 Volume Serial Number is 042E-11B5

Then I simply went ahead & updated the PATH variable to include this path & restarted eclipse.

The code compiles & debugging (GDB ) is working nicely.

Hope this helps.

You need to turn it on its head in terms of the way you're thinking about it. Instead of doing "in" to find the current item's user rights in a predefined set of applicable user rights, you're asking a predefined set of user rights if it contains the current item's applicable value. This is exactly the same way you would find an item in a regular list in .NET.

There are two ways of doing this using LINQ, one uses query syntax and the other uses method syntax. Essentially, they are the same and could be used interchangeably depending on your preference:

Query Syntax:

var selected = from u in users
               where new[] { "Admin", "User", "Limited" }.Contains(u.User_Rights)
               select u

foreach(user u in selected)
{
    //Do your stuff on each selected user;
}

Method Syntax:

var selected = users.Where(u => new[] { "Admin", "User", "Limited" }.Contains(u.User_Rights));

foreach(user u in selected)
{
    //Do stuff on each selected user;
}

My personal preference in this instance might be method syntax because instead of assigning the variable, I could do the foreach over an anonymous call like this:

foreach(User u in users.Where(u => new [] { "Admin", "User", "Limited" }.Contains(u.User_Rights)))
{
    //Do stuff on each selected user;
}

Syntactically this looks more complex, and you have to understand the concept of lambda expressions or delegates to really figure out what's going on, but as you can see, this condenses the code a fair amount.

It all comes down to your coding style and preference - all three of my examples do the same thing slightly differently.

An alternative way doesn't even use LINQ, you can use the same method syntax replacing "where" with "FindAll" and get the same result, which will also work in .NET 2.0:

foreach(User u in users.FindAll(u => new [] { "Admin", "User", "Limited" }.Contains(u.User_Rights)))
{
    //Do stuff on each selected user;
}

if you do any changes on git ignore then you have to clear you git cache also

> git rm -r --cached . 
> git add . 
> git commit -m 'git cache cleared'
> git push

if want to remove any particular folder or file then

git rm  --cached filepath/foldername

Use Invoke-RestMethod to consume REST-APIs. Save the JSON to a string and use that as the body, ex:

$JSON = @'
{"@type":"login",
 "username":"[email protected]",
 "password":"yyy"
}
'@

$response = Invoke-RestMethod -Uri "http://somesite.com/oneendpoint" -Method Post -Body $JSON -ContentType "application/json"

If you use Powershell 3, I know there have been some issues with Invoke-RestMethod, but you should be able to use Invoke-WebRequest as a replacement:

$response = Invoke-WebRequest -Uri "http://somesite.com/oneendpoint" -Method Post -Body $JSON -ContentType "application/json"

If you don't want to write your own JSON every time, you can use a hashtable and use PowerShell to convert it to JSON before posting it. Ex.

$JSON = @{
    "@type" = "login"
    "username" = "[email protected]"
    "password" = "yyy"
} | ConvertTo-Json

Here's some working C++ code which solves the problem.

Proof that the memory constraints are satisfied:

Editor: There is no proof of the maximum memory requirements offered by the author either in this post or in his blogs. Since the number of bits necessary to encode a value depends on the values previously encoded, such a proof is likely non-trivial. The author notes that the largest encoded size he could stumble upon empirically was 1011732, and chose the buffer size 1013000 arbitrarily.

typedef unsigned int u32;

namespace WorkArea
{
    static const u32 circularSize = 253250;
    u32 circular[circularSize] = { 0 };         // consumes 1013000 bytes

    static const u32 stageSize = 8000;
    u32 stage[stageSize];                       // consumes 32000 bytes

    ...

Together, these two arrays take 1045000 bytes of storage. That leaves 1048576 - 1045000 - 2×1024 = 1528 bytes for remaining variables and stack space.

It runs in about 23 seconds on my Xeon W3520. You can verify that the program works using the following Python script, assuming a program name of sort1mb.exe.

from subprocess import *
import random

sequence = [random.randint(0, 99999999) for i in xrange(1000000)]

sorter = Popen('sort1mb.exe', stdin=PIPE, stdout=PIPE)
for value in sequence:
    sorter.stdin.write('%08d\n' % value)
sorter.stdin.close()

result = [int(line) for line in sorter.stdout]
print('OK!' if result == sorted(sequence) else 'Error!')

A detailed explanation of the algorithm can be found in the following series of posts:

• 1MB Sorting Explained
• Arithmetic Coding and the 1MB Sorting Problem
• Arithmetic Encoding Using Fixed-Point Math

Try using

<table  border="1" cellspacing="0" cellpadding="0" class="template-table" 
style="table-layout: fixed; width: 100%"> 

as table style along with

<td style="word-break:break-word">long text</td>

for td it works for normal/real scenario text with words, not for random typed letters without gaps

I had the same problem, and I solved it by installing :

• Redistribuable Visual C++ pour Visual Studio 2012 Update 4 (6.9 MB)
• Redistributable Visual C++ pour Visual Studio 2015 Update 1 (14.1 MB)

NB : 64 bit installation was enough, I had to uninstall / reinstall Wamp after that

Pretty sure this solves what you're looking for:

HTML:

<table>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
</table>

Javascript (using jQuery):

$(document).ready(function(){
    $('.editbtn').click(function(){
        $(this).html($(this).html() == 'edit' ? 'modify' : 'edit');
    });
});

Edit:

Apparently I should have looked at your sample code first ;)

You need to change (at least) the ID attribute of each element. The ID is the unique identifier for each element on the page, meaning that if you have multiple items with the same ID, you'll get conflicts.

By using classes, you can apply the same logic to multiple elements without any conflicts.

Nicer code for this:

yourstring = yourstring.Replace(System.Environment.NewLine, string.Empty);

Working with Python 3 microservices or shell; using Ubuntu Server 18.04 (Bionic Beaver) or Ubuntu 19.10 (Eoan Ermine) or Ubuntu 18.10 (Cosmic Cuttlefish) I always do like these steps, and it worked always too:

1. Creating a microservice called p example "brain_microservice1.service" in my case:

   $ nano /lib/systemd/system/brain_microservice1.service
   

2. Inside this new service that you are in:

   [Unit]
   Description=brain_microservice_1
   After=multi-user.target
   
   [Service]
   Type=simple
   ExecStart=/usr/bin/python3.7 /root/scriptsPython/RUN_SERVICES/microservices    /microservice_1.py -k start -DFOREGROUND
   ExecStop=/usr/bin/python3.7 /root/scriptsPython/RUN_SERVICES/microservices/microservice_1.py -k graceful-stop
   ExecReload=/usr/bin/python3.7 /root/scriptsPython/RUN_SERVICES/microservices/microservice_1.py -k graceful
   PrivateTmp=true
   LimitNOFILE=infinity
   KillMode=mixed
   Restart=on-failure
   RestartSec=5s
   
   [Install]
   WantedBy=multi-user.target
   

3. Give the permissions:

   $ chmod -X /lib/systemd/system/brain_microservice*
   $ chmod -R 775 /lib/systemd/system/brain_microservice*
   

4. Give the execution permission then:

   $ systemctl daemon-reload
   

5. Enable then, this will make then always start on startup

   $ systemctl enable brain_microservice1.service
   

6. Then you can test it;

   $ sudo reboot now

7. Finish = SUCCESS!!

This can be done with the same body script to run shell, react ... database startup script ... any kind os code ... hope this help u...

...

$('#div1').attr('class')

will return a string of the classes. Turn it into an array of class names

var classNames = $('#div1').attr('class').split(' ');

For example,

package main

import "fmt"

func main() {
    type Map1 map[string]interface{}
    type Map2 map[string]int
    m := Map1{"foo": Map2{"first": 1}, "boo": Map2{"second": 2}}
    //m = map[foo:map[first: 1] boo: map[second: 2]]
    fmt.Println("m:", m)
    for k, v := range m {
        fmt.Println("k:", k, "v:", v)
    }
}

Output:

m: map[boo:map[second:2] foo:map[first:1]]
k: boo v: map[second:2]
k: foo v: map[first:1]

Interesting:

1. You declared an array var $my_value = array();
2. Pushed value into it $a->my_value[] = 'b';
3. Assigned a string to variable. (so it is no more array) $a->set_value ('c');
4. Tried to push a value into array, that does not exist anymore. (it's string) $a->my_class('d');

And your foreach wont work anymore.

I had a similar problem. I was using the "$. GetJSON" jQuery and everything worked perfectly in Firefox and Chrome.

But it did not work in IE. So I tried to directly access the URL of json, but in IE it asked if I wanted to download the file.

After much searching I saw that there must be a header in the result with a content-type, in my case, the content-type was:

header("Content-type: text/html; charset=iso-8859-1");

But when the page that made the request receives this json, in IE, you have to be specified SAME CONTENT-TYPE, in my case was:

$.getJSON (
"<? site_url php echo (" ajax / tipoMenu ")?>"
{contentType: 'text / html; charset = utf-8'},
function (result) {

hugs

People wouldn't like to see a wrong commit and a revert commit to undo changes of the wrong commit. This pollutes commit history.

Here is a simple way for removing the wrong commit instead of undoing changes with a revert commit.

1. git checkout my-pull-request-branch

2. git rebase -i HEAD~n // where n is the number of last commits you want to include in interactive rebase.

3. Replace pick with drop for commits you want to discard.
4. Save and exit.
5. git push --force

How about this?

fscanf(file,"%d %d %d %d %d %d %d",&line1_1,&line1_2, &line1_3, &line2_1, &line2_2, &line3_1, &line3_2); 

In this case spaces in fscanf match multiple occurrences of any whitespace until the next token in found.

time1 is the key of the most outer dictionary, eg, feb2012. So then you're trying to index the string, but you can only do this with integers. I think what you wanted was:

for info in courses[time1][course]:

As you're going through each dictionary, you must add another nest.

1) on your mac type

nano /usr/bin/wget

2) paste the following in

#!/bin/bash
curl -L $1 -o $2

3) close then make it executable

chmod 777 /usr/bin/wget

That's it.

Are you looking for the binary conversion?

double result = Double.longBitsToDouble(15552451L);

This will give you the double with the same bit pattern as the long literal.

Binary or hexadecimal literals will come in handy, here. Here are some examples.

double nan = Double.longBitsToDouble(0xfff0000000000001L);
double positiveInfinity = Double.longBitsToDouble(0x7ff0000000000000L);
double positiveInfinity = Double.longBitsToDouble(0xfff0000000000000L);

(See Double.longBitsToDouble(long))

You also can get the long back with

long bits = Double.doubleToRawLongBits(Double.NaN);

(See Double.doubleToRawLongBits(double))

As it is not stated anywhere in the current answers, the fastest solution if you are not embedding js into your template is:

Put <script type="text/javascript"> window.CSRF_TOKEN = "{{ csrf_token }}"; </script> before your reference to script.js file in your template, then add csrfmiddlewaretoken into your data dictionary in your js file:

$.ajax({
            type: 'POST',
            url: somepathname + "do_it/",
            data: {csrfmiddlewaretoken: window.CSRF_TOKEN},
            success: function() {
                console.log("Success!");
            }
        })

Java. Matrix multiplication.

Tested with matrices of different size.

        int mRRowLength = m1.length;    // m result rows length
        int mRColLength = m2[0].length; // m result columns length
        double[][] mResult = new double[mRRowLength][mRColLength];

DISCLAIMER: This solution is not 100% accurate in terms of determining the minimal width.

I was also figuring out how to measure text on a canvas. After reading the great post from mice i had some problems on how to measure multiline text. There is no obvious way from these contributions but after some research i cam across the StaticLayout class. It allows you to measure multiline text (text with "\n") and configure much more properties of your text via the associated Paint.

Here is a snippet showing how to measure multiline text:

private StaticLayout measure( TextPaint textPaint, String text, Integer wrapWidth ) {
    int boundedWidth = Integer.MAX_VALUE;
    if (wrapWidth != null && wrapWidth > 0 ) {
       boundedWidth = wrapWidth;
    }
    StaticLayout layout = new StaticLayout( text, textPaint, boundedWidth, Alignment.ALIGN_NORMAL, 1.0f, 0.0f, false );
    return layout;
}

The wrapwitdh is able to determin if you want to limit your multiline text to a certain width.

Since the StaticLayout.getWidth() only returns this boundedWidth you have to take another step to get the maximum width required by your multiline text. You are able to determine each lines width and the max width is the highest line width of course:

private float getMaxLineWidth( StaticLayout layout ) {
    float maxLine = 0.0f;
    int lineCount = layout.getLineCount();
    for( int i = 0; i < lineCount; i++ ) {
        if( layout.getLineWidth( i ) > maxLine ) {
            maxLine = layout.getLineWidth( i );
        }
    }
    return maxLine;
}

byte test[] = new byte[3];
test[0] = 0x0A;
test[1] = 0xFF;
test[2] = 0x01;

for (byte theByte : test)
{
  System.out.println(Integer.toHexString(theByte));
}

NOTE: test[1] = 0xFF; this wont compile, you cant put 255 (FF) into a byte, java will want to use an int.

you might be able to do...

test[1] = (byte) 0xFF;

I'd test if I was near my IDE (if I was near my IDE I wouln't be on Stackoverflow)

My problem went away after I shutdowned VirtualBox on my machine.

One thing I know is that Linux KVM can't get along with VirtualBox well.

I found another solution for recent version of NPM. What I want to do is to replace all the "*" dependencies with the explicit lastest version number. None of the methods discussed has worked for me.

What I did:

1. Replace all "*" with "^0.0.0"
2. Run npm-check-updates -u

Everything in package.json now is updated to the last version.

To answer the original question "Why is php not running?" The file your browser is asking for must have the .php extension. If the file has the .html extension, php will not be executed.

You can easily transition your WSDL-spewing WCF web components to other uses just by changing your configuration settings. You can go across HTTP and then also named pipes, tcp, custom protocols, etc without having to change your code. I believe WCF components may also be easier to set up for stuff like security, two-way calling, transactions, concurrency, etc.

REST pretty much limits you to HTTP (which is fine in many cases).

If sql server is installed on your machine, you should check

Programs -> Microsoft SQL Server 20XX -> Configuration Tools -> SQL Server Configuration Manager -> SQL Server Services You'll see "SQL Server (MSSQLSERVER)"

Programs -> Microsoft SQL Server 20XX -> Configuration Tools -> SQL Server Configuration Manager -> SQL Server Network Configuration -> Protocols for MSSQLSERVER -> TCP/IP Make sure it's using port number 1433

If you want to see if the port is open and listening try this from your command prompt... telnet 127.0.0.1 1433

And yes, SQL Express installs use localhost\SQLEXPRESS as the instance name by default.

Example of uppercasedFirstCharacter convenience property in Swift3 and Swift4.

Property uppercasedFirstCharacterNew demonstrates how to use String slicing subscript in Swift4.

extension String {

   public var uppercasedFirstCharacterOld: String {
      if characters.count > 0 {
         let splitIndex = index(after: startIndex)
         let firstCharacter = substring(to: splitIndex).uppercased()
         let sentence = substring(from: splitIndex)
         return firstCharacter + sentence
      } else {
         return self
      }
   }

   public var uppercasedFirstCharacterNew: String {
      if characters.count > 0 {
         let splitIndex = index(after: startIndex)
         let firstCharacter = self[..<splitIndex].uppercased()
         let sentence = self[splitIndex...]
         return firstCharacter + sentence
      } else {
         return self
      }
   }
}

let lorem = "lorem".uppercasedFirstCharacterOld
print(lorem) // Prints "Lorem"

let ipsum = "ipsum".uppercasedFirstCharacterNew
print(ipsum) // Prints "Ipsum"

Strangely, even though the tensorflow website 1 mentions that CUDA 10.1 is compatible with tensorflow-gpu-1.13.1, it doesn't work so far. tensorflow-gpu gets installed properly though but it throws out weird errors when running.

So far, the best configuration to run tensorflow with GPU is CUDA 9.0 with tensorflow_gpu-1.12.0 under python3.6.

Following this configuration with the steps mentioned in https://stackoverflow.com/a/51307381/2562870 (the answer above), worked for me :)

I got this same issue when I had the following configuration in my config/models.js

module.exports.models = {
  connection: 'mongodb',
  migrate: 'alter'
}

Changing migrate from 'alter' to 'safe' fixed it for me.

module.exports.models = {
  connection: 'mongodb',
  migrate: 'safe'
}

I tried this:

import pandas as p
import numpy as n

closingValue = p.read_csv("<FILENAME>", usecols=[4], dtype=float)
print(closingValue)

As of version 4.0.0, events such as select2-selecting, no longer work. They are renamed as follows:

• select2-close is now select2:close
• select2-open is now select2:open
• select2-opening is now select2:opening
• select2-selecting is now select2:selecting
• select2-removed is now select2:removed
• select2-removing is now select2:unselecting

This will print all the keys and values on localStorage:

ES6:

for (let i=0; i< localStorage.length; i++) {
    let key = localStorage.key(i);
    let value = localStorage[key];
    console.log(`localStorage ${key}:  ${value}`);
}

to convert YYYY-MM-DD string to datetime object, datetime.fromisoformat could be used.

from datetime import datetime

date_string = "2012-12-12 10:10:10"
print (datetime.fromisoformat(date_string))
2012-12-12 10:10:10

Close, you can use

$('#select_2 option:selected').html()

I have fixed the similar issue by passing associative array as the first argument inside Builder::with method.

Imagine you want to include child relations by some dynamic parameters but don't want to filter parent results.

Model.php

public function child ()
{
    return $this->hasMany(ChildModel::class);
}

Then, in other place, when your logic is placed you can do something like filtering relation by HasMany class. For example (very similar to my case):

$search = 'Some search string';
$result = Model::query()->with(
    [
        'child' => function (HasMany $query) use ($search) {
            $query->where('name', 'like', "%{$search}%");
        }
    ]
);

Then you will filter all the child results but parent models will not filter. Thank you for attention.

Wikipedia has the answer, along with a number of other sources.

A segfault basically means you did something bad with pointers. This is probably a segfault:

char *c = NULL;
...
*c; // dereferencing a NULL pointer

Or this:

char *c = "Hello";
...
c[10] = 'z'; // out of bounds, or in this case, writing into read-only memory

Or maybe this:

char *c = new char[10];
...
delete [] c;
...
c[2] = 'z'; // accessing freed memory

Same basic principle in each case - you're doing something with memory that isn't yours.

For me its solved follow the following steps :

One reason for this occur is if you don't have a start page or wrong start page set under your web project's properties. So do this:

1- Right click on your MVC project

2- Choose "Properties"

3- Select the "Web" tab

4- Select "Specific Page"

Assuming you have a controller called HomeController and an action method called Index, enter "home/index" in to the text box corresponding to the "Specific Page" radio button.

Now, if you launch your web application, it will take you to the view rendered by the HomeController's Index action method.

You can create subset of data with your condition and then use shape or len:

print df
  col1 education
0    a       9th
1    b       9th
2    c       8th

print df.education == '9th'
0     True
1     True
2    False
Name: education, dtype: bool

print df[df.education == '9th']
  col1 education
0    a       9th
1    b       9th

print df[df.education == '9th'].shape[0]
2
print len(df[df['education'] == '9th'])
2

Performance is interesting, the fastest solution is compare numpy array and sum:

Code:

import perfplot, string
np.random.seed(123)


def shape(df):
    return df[df.education == 'a'].shape[0]

def len_df(df):
    return len(df[df['education'] == 'a'])

def query_count(df):
    return df.query('education == "a"').education.count()

def sum_mask(df):
    return (df.education == 'a').sum()

def sum_mask_numpy(df):
    return (df.education.values == 'a').sum()

def make_df(n):
    L = list(string.ascii_letters)
    df = pd.DataFrame(np.random.choice(L, size=n), columns=['education'])
    return df

perfplot.show(
    setup=make_df,
    kernels=[shape, len_df, query_count, sum_mask, sum_mask_numpy],
    n_range=[2**k for k in range(2, 25)],
    logx=True,
    logy=True,
    equality_check=False, 
    xlabel='len(df)')

You can rename the file using FSO by moving it: MoveFile Method.

Dim Fso
Set Fso = WScript.CreateObject("Scripting.FileSystemObject")
Fso.MoveFile "A.txt", "B.txt"

An example:

log4j.rootLogger=ERROR, logfile

log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.logfile.datePattern='-'dd'.log'
log4j.appender.logfile.File=log/radius-prod.log
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%-6r %d{ISO8601} %-5p %40.40c %x - %m\n

log4j.logger.foo.bar.Baz=DEBUG, myappender
log4j.additivity.foo.bar.Baz=false

log4j.appender.myappender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.myappender.datePattern='-'dd'.log'
log4j.appender.myappender.File=log/access-ext-dmz-prod.log
log4j.appender.myappender.layout=org.apache.log4j.PatternLayout
log4j.appender.myappender.layout.ConversionPattern=%-6r %d{ISO8601} %-5p %40.40c %x - %m\n

This can be as simple as:

SQL> ALTER SYSTEM ENABLE RESTRICTED SESSION;

SQL> DROP USER test CASCADE;

SQL> ALTER SYSTEM DISABLE RESTRICTED SESSION;

this is how I do it

function run_ajax(obj) {
    $.ajax({
        type:"POST",
        url: prefix,
        data: obj.pdata,
        dataType: 'json',
        error: function(data) {
            //do error stuff
        },
        success: function(data) {

            if(obj.func){
                obj.func(data); 
            }

        }
    });
}

alert_func(data){
    //do what you want with data
}

var obj= {};
obj.pdata = {sumbit:"somevalue"}; // post variable data
obj.func = alert_func;
run_ajax(obj);

Here's a little help on delegates between two view controllers:

Step 1: Make a protocol in the UIViewController that you will be removing/will be sending the data.

protocol FooTwoViewControllerDelegate:class {
    func myVCDidFinish(_ controller: FooTwoViewController, text: String)
}

Step2: Declare the delegate in the sending class (i.e. UIViewcontroller)

class FooTwoViewController: UIViewController {
    weak var delegate: FooTwoViewControllerDelegate?
    [snip...]
}

Step3: Use the delegate in a class method to send the data to the receiving method, which is any method that adopts the protocol.

@IBAction func saveColor(_ sender: UIBarButtonItem) {
        delegate?.myVCDidFinish(self, text: colorLabel.text) //assuming the delegate is assigned otherwise error
}

Step 4: Adopt the protocol in the receiving class

class ViewController: UIViewController, FooTwoViewControllerDelegate {

Step 5: Implement the delegate method

func myVCDidFinish(_ controller: FooTwoViewController, text: String) {
    colorLabel.text = "The Color is " +  text
    controller.navigationController.popViewController(animated: true)
}

Step 6: Set the delegate in the prepareForSegue:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "mySegue" {
        let vc = segue.destination as! FooTwoViewController
        vc.colorString = colorLabel.text
        vc.delegate = self
    }
}

And that should work. This is of course just code fragments, but should give you the idea. For a long explanation of this code you can go over to my blog entry here:

segues and delegates

If you are interested in what's going on under the hood with a delegate I did write on that here:

under the hood with delegates

You could use a simple Union + Distinct:

var lines = lines2.Union(lines3).Distinct();

That will add all the items from the second list into the first list, and then return all the unique strings in the combined list. Not likely to perform well with large lists, but it's simple.

Reference: http://msdn.microsoft.com/en-us/library/bb341731.aspx

public static boolean isStringBlank(final CharSequence cs) {
        int strLen;
        if (cs == null || (strLen = cs.length()) == 0) {
            return true;
        }
        for (int i = 0; i < strLen; i++) {
            if (!Character.isWhitespace(cs.charAt(i))) {
                return false;
            }
        }
        return true;
    }

Rather than create 2 temporary dfs you can just pass these as params within a dict using the DataFrame constructor:

pd.DataFrame({'email':sf.index, 'list':sf.values})

There are lots of ways to construct a df, see the docs

I was getting from a conflict with join table defined in an association class ( with additional custom fields ) annotation and a join table defined in a many-to-many annotation.

The mapping definitions in two entities with a direct many-to-many relationship appeared to result in the automatic creation of the join table using the 'joinTable' annotation. However the join table was already defined by an annotation in its underlying entity class and I wanted it to use this association entity class's own field definitions so as to extend the join table with additional custom fields.

The explanation and solution is that identified by FMaz008 above. In my situation, it was thanks to this post in the forum 'Doctrine Annotation Question'. This post draws attention to the Doctrine documentation regarding ManyToMany Uni-directional relationships. Look at the note regarding the approach of using an 'association entity class' thus replacing the many-to-many annotation mapping directly between two main entity classes with a one-to-many annotation in the main entity classes and two 'many-to-one' annotations in the associative entity class. There is an example provided in this forum post Association models with extra fields:

public class Person {

  /** @OneToMany(targetEntity="AssignedItems", mappedBy="person") */
  private $assignedItems;

}

public class Items {

    /** @OneToMany(targetEntity="AssignedItems", mappedBy="item") */
    private $assignedPeople;
}

public class AssignedItems {

    /** @ManyToOne(targetEntity="Person")
    * @JoinColumn(name="person_id", referencedColumnName="id")
    */
private $person;

    /** @ManyToOne(targetEntity="Item")
    * @JoinColumn(name="item_id", referencedColumnName="id")
    */
private $item;

}

You are disabling only on document.ready and this happens only once when DOM is ready but you need to disable in keyup event too when textbox gets empty. Also change $(this).val.length to $(this).val().length

$(document).ready(function(){
    $('.sendButton').attr('disabled',true);
    $('#message').keyup(function(){
        if($(this).val().length !=0)
            $('.sendButton').attr('disabled', false);            
        else
            $('.sendButton').attr('disabled',true);
    })
});

Or you can use conditional operator instead of if statement. also use prop instead of attr as attribute is not recommended by jQuery 1.6 and above for disabled, checked etc.

As of jQuery 1.6, the .attr() method returns undefined for attributes that have not been set. To retrieve and change DOM properties such as the checked, selected, or disabled state of form elements, use the .prop() method, jQuery docs

$(document).ready(function(){
    $('.sendButton').prop('disabled',true);
    $('#message').keyup(function(){
        $('.sendButton').prop('disabled', this.value == "" ? true : false);     
    })
});  

Mysql has this handy UPDATE INTO command ;)

edit Looks like they renamed it to REPLACE

REPLACE works exactly like INSERT, except that if an old row in the table has the same value as a new row for a PRIMARY KEY or a UNIQUE index, the old row is deleted before the new row is inserted

Check out jQuery.floatThead (demos available) which is very cool, can work with DataTables too, and can even work inside an overflow: auto container.

As answered previously, you do not need to set the environment variable on the remote host. Instead, you can simply do the meta-expansion on the local host, and pass the value to the remote host.

ssh [email protected] '~/tools/run_pvt.pl $BUILD_NUMBER'

If you really want to set the environment variable on the remote host and use it, you can use the env program

ssh [email protected] "env BUILD_NUMBER=$BUILD_NUMBER ~/tools/run_pvt.pl \$BUILD_NUMBER"

In this case this is a bit of an overkill, and note

• env BUILD_NUMBER=$BUILD_NUMBER does the meta expansion on the local host
• the remote BUILD_NUMBER environment variable will be used by
  the remote shell

this way worked for me

Profile pictures are scaled down to 125x125 on the facebook sever when they're uploaded, so as far as I know you can't get pictures bigger than that. How big is the picture you're getting?

Random Number of Random Items from an Array

def random_items(array)
  array.sample(1 + rand(array.count))
end

Examples of possible results:

my_array = ["one", "two", "three"]
my_array.sample(1 + rand(my_array.count))

=> ["two", "three"]
=> ["one", "three", "two"]
=> ["two"]

Hash tables are O(1) average and amortized case complexity, however it suffers from O(n) worst case time complexity. [And I think this is where your confusion is]

Hash tables suffer from O(n) worst time complexity due to two reasons:

1. If too many elements were hashed into the same key: looking inside this key may take O(n) time.
2. Once a hash table has passed its load balance - it has to rehash [create a new bigger table, and re-insert each element to the table].

However, it is said to be O(1) average and amortized case because:

1. It is very rare that many items will be hashed to the same key [if you chose a good hash function and you don't have too big load balance.
2. The rehash operation, which is O(n), can at most happen after n/2 ops, which are all assumed O(1): Thus when you sum the average time per op, you get : (n*O(1) + O(n)) / n) = O(1)

Note because of the rehashing issue - a realtime applications and applications that need low latency - should not use a hash table as their data structure.

EDIT: Annother issue with hash tables: cache
Another issue where you might see a performance loss in large hash tables is due to cache performance. Hash Tables suffer from bad cache performance, and thus for large collection - the access time might take longer, since you need to reload the relevant part of the table from the memory back into the cache.

This is how you do it:

git stash push -m "my_stash"

Where "my_stash" is the stash name.

Some more useful things to know: All the stashes are stored in a stack. Type:

git stash list

This will list down all your stashes.

To apply a stash and remove it from the stash stack, type:

git stash pop stash@{n}

To apply a stash and keep it in the stash stack, type:

git stash apply stash@{n}

Where n is the index of the stashed change.

I realize this is a bit late, but I've had success with annotating a timestamp column with

@Column(name="timestamp", columnDefinition="TIMESTAMP DEFAULT CURRENT_TIMESTAMP")

This should also work with CURRENT_DATE and CURRENT_TIME. I'm using JPA/Hibernate with Oracle, so YMMV.

The $.grep() method eliminates items from an array as necessary so that only remaining items carry a given search. The test is a function that is passed an array item and the index of the item within the array. Only if the test returns true will the item be in the result array.

Use traits as base classes. Then use them in a parent class. Extend it .

trait business{
  function sell(){

  }

  function buy(){

  }

  function collectMoney(){
  }

}

trait human{

   function think(){

   }

   function speak(){

   }

}

class BusinessPerson{
  use business;
  use human;
  // If you have more traits bring more
}


class BusinessWoman extends BusinessPerson{

   function getPregnant(){

   }

}


$bw = new BusinessWoman();
$bw ->speak();
$bw->getPregnant();

See now business woman logically inherited business and human both;

If you are using getActivity() then you have to make sure that the calling activity is added already. If activity has not been added in such case so you may get null when you call getActivity()

in such cases getContext() is safe

then the code for starting the activity will be slightly changed like,

Intent intent = new Intent(getContext(), mFragmentFavorite.class);
startActivity(intent);

Activity, Service and Application extends ContextWrapper class so you can use this or getContext() or getApplicationContext() in the place of first argument.

Another reply to your questions (assuming you are on master and already did "git fetch origin" to make you repo aware about remote changes):

1) Commits on remote branch since when local branch was created:

git diff HEAD...origin/master

2) I assume by "working copy" you mean your local branch with some local commits that are not yet on remote. To see the differences of what you have on your local branch but that does not exist on remote branch run:

git diff origin/master...HEAD

3) See the answer by dbyrne.

This behaves as expected. The URLEncoder implements the HTML Specifications for how to encode URLs in HTML forms.

From the javadocs:

This class contains static methods for converting a String to the application/x-www-form-urlencoded MIME format.

and from the HTML Specification:

application/x-www-form-urlencoded

Forms submitted with this content type must be encoded as follows:

1. Control names and values are escaped. Space characters are replaced by `+'

You will have to replace it, e.g.:

System.out.println(java.net.URLEncoder.encode("Hello World", "UTF-8").replace("+", "%20"));

The below steps for using Android OpenCV sdk in Android Studio. This is a simplified version of this(1) SO answer.

1. Download latest OpenCV sdk for Android from OpenCV.org and decompress the zip file.
2. Import OpenCV to Android Studio, From File -> New -> Import Module, choose sdk/java folder in the unzipped opencv archive.
3. Update build.gradle under imported OpenCV module to update 4 fields to match your project build.gradle a) compileSdkVersion b) buildToolsVersion c) minSdkVersion and d) targetSdkVersion.
4. Add module dependency by Application -> Module Settings, and select the Dependencies tab. Click + icon at bottom, choose Module Dependency and select the imported OpenCV module.
   • For Android Studio v1.2.2, to access to Module Settings : in the project view, right-click the dependent module -> Open Module Settings
5. Copy libs folder under sdk/native to Android Studio under app/src/main.
6. In Android Studio, rename the copied libs directory to jniLibs and we are done.

Step (6) is since Android studio expects native libs in app/src/main/jniLibs instead of older libs folder. For those new to Android OpenCV, don't miss below steps

• include static{ System.loadLibrary("opencv_java"); } (Note: for OpenCV version 3 at this step you should instead load the library opencv_java3.)
• For step(5), if you ignore any platform libs like x86, make sure your device/emulator is not on that platform.

OpenCV written is in C/C++. Java wrappers are

1. Android OpenCV SDK - OpenCV.org maintained Android Java wrapper. I suggest this one.
2. OpenCV Java - OpenCV.org maintained auto generated desktop Java wrapper.
3. JavaCV - Popular Java wrapper maintained by independent developer(s). Not Android specific. This library might get out of sync with OpenCV newer versions.

You mean:

Wscript.Echo "Like this?"

If you run that under wscript.exe (the default handler for the .vbs extension, so what you'll get if you double-click the script) you'll get a "MessageBox" dialog with your text in it. If you run that under cscript.exe you'll get output in your console window.

This was happening with me today and I resolved it in following way.

Machine: I'm using Windows 10 machine and downloaded the latest MongoDB - Community edition.

So, the problem was, I did not have C:\data\db created.

Without creating C:\data\db, I opened CMD terminal and started the database using mongod command at terminal

C:\YourInstallationPath\bin>mongod

And when I fired mongo command then I was getting the problem.

Twist, I created the necessary folders but still was getting the problem. And this is because mongo server was already running. To fix it, I fired up mongod command again, and it automatically referenced to C:\data\db.

Other users have suggested to add C:\data\db but did not talk about executing mongod again, which exactly solved my problem.

Check this fiddle. You are going to need to take a look at using border-collapse and border-spacing. There are some quirks for IE (as usual). This is based on an answer to this question.

table.test td {
  background-color: lime;
  margin: 12px 12px 12px 12px;
  padding: 12px 12px 12px 12px;
}

table.test {
  border-collapse: separate;
  border-spacing: 10px;
  *border-collapse: expression('separate', cellSpacing='10px');
}

<table class="test">
  <tr>
    <td>Cell</td>
    <td>Cell</td>
    <td>Cell</td>
  </tr>
  <tr>
    <td>Cell</td>
    <td>Cell</td>
    <td>Cell</td>
  </tr>
  <tr>
    <td>Cell</td>
    <td>Cell</td>
    <td>Cell</td>
  </tr>
</table>

sudo psql --host=localhost --dbname=database-name --username=postgres

This solved my issue

parent.children is not an array. It is HTMLCollection and it does not have forEach method. You can convert it to the array first. For example in ES6:

Array.from(parent.children).forEach(child => {
    console.log(child)
});

or using spread operator:

[...parent.children].forEach(function (child) {
    console.log(child)
});

Most of the modern day browsers consider checked="anything" as checked="true".

You might have to remove the checked attribute if that makes sense in your case, one of which might be related to when you load the page.

$(this).removeAttr('checked')

This might help you in cases when you want your radio button to be checked adhering to some condition. You can simply remove the attribute to achieve that.

PS: Not helpful in all the cases.

Gotcha!

You have to use RegisterStartupScript instead of RegisterClientScriptBlock

Here My Example.

MasterPage:

<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="MasterPage.master.cs"
    Inherits="prueba.MasterPage" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    <script type="text/javascript">

        function confirmCallBack() {
            var a = document.getElementById('<%= Page.Master.FindControl("ContentPlaceHolder1").FindControl("Button1").ClientID %>');

            alert(a.value);

        }

    </script>

    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            ClientScript.RegisterStartupScript(this.GetType(), "js", "confirmCallBack();", true);

        }
    }
}

i think this is simple than other by using [Editable(false)] attribute

for example:

 public class MyModel
    {
        [Editable(false)]
        public string userName { get; set; }
    }

Kotlin version below (Updated version of @paul-burke response:

fun openPDFDocument(context: Context, filename: String) {
    //Create PDF Intent
    val pdfFile = File(Environment.getExternalStorageDirectory().absolutePath + "/" + filename)
    val pdfIntent = Intent(Intent.ACTION_VIEW)
    pdfIntent.setDataAndType(Uri.fromFile(pdfFile), "application/pdf")
    pdfIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY)

    //Create Viewer Intent
    val viewerIntent = Intent.createChooser(pdfIntent, "Open PDF")
    context.startActivity(viewerIntent)
}

import subprocess
result = []
win_cmd = 'ipconfig'(curr_user,filename,ip_address)
process = subprocess.Popen(win_cmd,
shell=True,
stdout=subprocess.PIPE,
stderr=subprocess.PIPE )
for line in process.stdout:
    print line
result.append(line)
errcode = process.returncode
for line in result:
    print line

This cannot be done in one statement. You will have to use 2 statements

DELETE FROM TB1 WHERE PersonID = '2';
DELETE FROM TB2 WHERE PersonID = '2';

Its much better to use java.util.LinkedList, because it's probably much more optimized, than the one that you will write.

It's working exactly as it's supposed to. The transpose of a 1D array is still a 1D array! (If you're used to matlab, it fundamentally doesn't have a concept of a 1D array. Matlab's "1D" arrays are 2D.)

If you want to turn your 1D vector into a 2D array and then transpose it, just slice it with np.newaxis (or None, they're the same, newaxis is just more readable).

import numpy as np
a = np.array([5,4])[np.newaxis]
print(a)
print(a.T)

Generally speaking though, you don't ever need to worry about this. Adding the extra dimension is usually not what you want, if you're just doing it out of habit. Numpy will automatically broadcast a 1D array when doing various calculations. There's usually no need to distinguish between a row vector and a column vector (neither of which are vectors. They're both 2D!) when you just want a vector.

I think I see your problem, you need to use the @ syntax to define parameters you will pass in this way, also I'm not sure what loginID or password are doing you don't seem to define them anywhere and they are not being used as URL parameters so are they being sent as query parameters?

This is what I can suggest based on what I see so far:

.factory('MagComments', function ($resource) {
    return $resource('http://localhost/dooleystand/ci/api/magCommenct/:id', {
      loginID : organEntity,
      password : organCommpassword,
      id : '@magId'
    });
  })

The @magId string will tell the resource to replace :id with the property magId on the object you pass it as parameters.

I'd suggest reading over the documentation here (I know it's a bit opaque) very carefully and looking at the examples towards the end, this should help a lot.

([[][a-z \s]+[]])

Above should work given the following explaination

• characters within square brackets[] defines characte class which means pattern should match atleast one charcater mentioned within square brackets

• \s specifies a space

•  + means atleast one of the character mentioned previously to +.

Installing a 64-bit version of Java will solve the issue. Go to page Java Downloads for All Operating Systems

This is a problem due to the incompatibility of the Java version and the Eclipse version both should be 64 bit if you are using a 64-bit system.

Note that it is now possible to use some of C++11 std::thread in the win32 threading mode. These header-only adapters worked out of the box for me: https://github.com/meganz/mingw-std-threads

From the revision history it looks like there is some recent attempt to make this a part of the mingw64 runtime.

You are binding the click event to anchors with an href attribute with value sign_new.

Either bind anchors with class sign_new or bind anchors with href value #sign_up. I would prefer the former.

It is actually called file:///android_asset/index.html

file:///android_assets/index.html will give you a build error.

I used (the suggested answer from above)

sudo apt-get install eclipse eclipse-cdt g++

but ONLY after then also doing

sudo eclipse -clean

Hope that also helps.

Let's make it simple:

df[nrow(df) + 1,] = c("v1","v2")

Okay here is a simple fix.

This error popped in front of me when I tried to manually change .jpg file to .png and then was copying & pasting it in my 'drawable' folder.

I rebuild and cleaned Project many times but nothing happened, then I removed that .png image and replaced that file with a different pre-existing .png image (or you can change it by help of paint and then paste it in drawable folder)

Now rebuild and clean the project . It works.

Hope it helps..!

Various permissions that you can grant to a user are

ALL PRIVILEGES- This would allow a MySQL user all access to a designated database (or if no database is selected, across the system)
CREATE- allows them to create new tables or databases
DROP- allows them to them to delete tables or databases
DELETE- allows them to delete rows from tables
INSERT- allows them to insert rows into tables
SELECT- allows them to use the Select command to read through databases
UPDATE- allow them to update table rows
GRANT OPTION- allows them to grant or remove other users' privileges

To provide a specific user with a permission, you can use this framework:

GRANT [type of permission] ON [database name].[table name] TO ‘[username]’@'localhost’;

I found this article very helpful

Updated Answer

Here I am giving 3 approaches for the same.

[1] Math Solution using Math.Truncate

 var float_number = 12.345;
 var result = float_number - Math.Truncate(float_number);

// input : 1.05
// output : "0.050000000000000044"

// input : 10.2
// output : 0.19999999999999929

If this is not the result what you are expecting, then you have to change the result to the form which you want (but you might do some string manipulations again.)

[2] using multiplier [which is 10 to the power of N (e.g. 10² or 10³) where N is the number of decimal places]

       // multiplier is " 10 to the power of 'N'" where 'N' is the number 
       // of decimal places
       int multiplier = 1000;  
       double double_value = 12.345;
       int double_result = (int)((double_value - (int)double_value) * multiplier);

// output 345

If the number of decimal places is not fixed, then this approach may create problems.

[3] using "Regular Expressions (REGEX)"

we should be very careful while writing solutions with string. This would not be preferable except some cases.

If you are going to do some string operations with decimal places, then this would be preferable

    string input_decimal_number = "1.50";
    var regex = new System.Text.RegularExpressions.Regex("(?<=[\\.])[0-9]+");
    if (regex.IsMatch(input_decimal_number))
    {
        string decimal_places = regex.Match(input_decimal_number).Value;
    }

// input : "1.05"
// output : "05"

// input : "2.50"
// output : "50"

// input : "0.0550"
// output : "0550"

you can find more about Regex on http://www.regexr.com/

1) Locate server.xml in {Tomcat installation folder}\ conf \ 2) Find following similar statement

       <!-- Define a non-SSL HTTP/1.1 Connector on port 8180 -->
      <Connector port="8080" maxHttpHeaderSize="8192"
           maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           connectionTimeout="20000" disableUploadTimeout="true" />

For example

<Connector port="8181" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

Edit and save the server.xml file. Restart Tomcat. Done

Easier solution;

#/bin/bash
if (( ${1:-2} >= 2 )); then
    echo "First parameter must be 0 or 1"
fi
# rest of script...

Output

$ ./test 
First parameter must be 0 or 1
$ ./test 0
$ ./test 1
$ ./test 4
First parameter must be 0 or 1
$ ./test 2
First parameter must be 0 or 1

Explanation

• (( )) - Evaluates the expression using integers.
• ${1:-2} - Uses parameter expansion to set a value of 2 if undefined.
• >= 2 - True if the integer is greater than or equal to two 2.

Just a side note for similar problem (If we don't want to loop through):

How to lookup a dictionary using a variable key within Jinja template?

Here is an example:

{% set key = target_db.Schema.upper()+"__"+target_db.TableName.upper() %}
{{ dict_containing_df.get(key).to_html() | safe }}

It might be obvious. But we don't need curly braces within curly braces. Straight python syntax works. (I am posting because I was confusing to me...)

Alternatively, you can simply do

{{dict[target_db.Schema.upper()+"__"+target_db.TableName.upper()]).to_html() | safe }}

But it will spit an error when no key is found. So better to use get in Jinja.

Try using Replace to see if it will work for you. The problem as I see it which has been mentioned a few times above is the CDate function is choking on the periods. You can use replace to change them to slashes. To answer your question about a Function in vba that can parse any date format, there is not any you have very limited options.

Dim current as Date, highest as Date, result() as Date 
For Each itemDate in DeliveryDateArray
    Dim tempDate As String
    itemDate = IIf(Trim(itemDate) = "", "0", itemDate) 'Added per OP's request.
    tempDate = Replace(itemDate, ".", "/")
    current = Format(CDate(tempDate),"dd/mm/yyyy")
    if current > highest then 
        highest = current 
    end if 
    ' some more operations an put dates into result array 
Next itemDate 
'After activating final sheet... 
Range("A1").Resize(UBound(result), 1).Value = Application.Transpose(result) 

This will get you the hours, minutes and second. hey presto.

Remote scenario. But if you're trying to run tests in a rails app, and you get something like

"ActiveRecord::StatementInvalid: PG::ObjectInUse: ERROR: database "myapp_test" is being accessed by other users DETAIL: There is 1 other session using the database."

Make sure you close pgAdmin or any other postgres GUI tools before running tests.

In MainActivity.java

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

        TextView tvView = (TextView) findViewById(R.id.tvView);

        AssetsReader assetsReader = new AssetsReader(this);
        if(assetsReader.getTxtFile(your_file_title)) != null)
        {
            tvView.setText(assetsReader.getTxtFile(your_file_title)));
        }
    }

Also, you can create separate class that does all the work

public class AssetsReader implements Readable{

    private static final String TAG = "AssetsReader";


    private AssetManager mAssetManager;
    private Activity mActivity;

    public AssetsReader(Activity activity) {
        this.mActivity = activity;
        mAssetManager = mActivity.getAssets();
    }

    @Override
    public String getTxtFile(String fileName)
    {
        BufferedReader reader = null;
        InputStream inputStream = null;
        StringBuilder builder = new StringBuilder();

        try{
            inputStream = mAssetManager.open(fileName);
            reader = new BufferedReader(new InputStreamReader(inputStream));

            String line;

            while((line = reader.readLine()) != null)
            {
                Log.i(TAG, line);
                builder.append(line);
                builder.append("\n");
            }
        } catch (IOException ioe){
            ioe.printStackTrace();
        } finally {

            if(inputStream != null)
            {
                try {
                    inputStream.close();
                } catch (IOException ioe){
                    ioe.printStackTrace();
                }
            }

            if(reader != null)
            {
                try {
                    reader.close();
                } catch (IOException ioe)
                {
                    ioe.printStackTrace();
                }
            }
        }
        Log.i(TAG, "builder.toString(): " + builder.toString());
        return builder.toString();
    }
}

In my opinion it's better to create an interface, but it's not neccessary

public interface Readable {
    /**
     * Reads txt file from assets
     * @param fileName
     * @return string
     */
    String getTxtFile(String fileName);
}

Works for me.

<div ng-show="$scope.showme === true">Hello World</div>
<div ng-repeat="a in $scope.bigdata" ng-init="$scope.showme = true">{{ a.title }}</div>

you can also use good old sscanf.

CString s;
int i;
int j = _stscanf(s, _T("%d"), &i);
if (j != 1)
{
   // tranfer didn't work
}

using jQuery it's easy...

 $('YOUR CLASS SELECTOR').click(function(){

            $(this).toggle();
});

^(-+)?[1-9][0-9]*$ starts with a - or + for 0 or 1 times, then you want a non zero number (because there is not such a thing -0 or +0) and then it continues with any number from 0 to 9

WARNING: Security researches have found several poisoned packages on PyPI, including a package named urllib, which will 'phone home' when installed. If you used pip install urllib some time after June 2017, remove that package as soon as possible.

You can't, and you don't need to.

urllib2 is the name of the library included in Python 2. You can use the urllib.request library included with Python 3, instead. The urllib.request library works the same way urllib2 works in Python 2. Because it is already included you don't need to install it.

If you are following a tutorial that tells you to use urllib2 then you'll find you'll run into more issues. Your tutorial was written for Python 2, not Python 3. Find a different tutorial, or install Python 2.7 and continue your tutorial on that version. You'll find urllib2 comes with that version.

Alternatively, install the requests library for a higher-level and easier to use API. It'll work on both Python 2 and 3.

To answer your question, the current method would be to create the object then call the method:

$functions = new Functions();
$var = $functions->filter($_GET['params']);

Another way would be to make the method static since the class has no private data to rely on:

public static function filter($data){

This can then be called like so:

$var = Functions::filter($_GET['params']);

Lastly, you do not need a class and can just have a file of functions which you include. So you remove the class Functions and the public in the method. This can then be called like you tried:

$var = filter($_GET['params']);

A temporary table can have 3 kinds, the # is the most used. This is a temp table that only exists in the current session. An equivalent of this is @, a declared table variable. This has a little less "functions" (like indexes etc) and is also only used for the current session. The ## is one that is the same as the #, however, the scope is wider, so you can use it within the same session, within other stored procedures.

You can create a temp table in various ways:

declare @table table (id int)
create table #table (id int)
create table ##table (id int)
select * into #table from xyz

I guess this answer will just be lost in between all the other ones, but anyway, here goes.

I ended up on this question via Google because I wanted to check if a string was numeric so that I could just use double.Parse("123") instead of the TryParse() method.

Why? Because it's annoying to have to declare an out variable and check the result of TryParse() before you know if the parse failed or not. I want to use the ternary operator to check if the string is numerical and then just parse it in the first ternary expression or provide a default value in the second ternary expression.

Like this:

var doubleValue = IsNumeric(numberAsString) ? double.Parse(numberAsString) : 0;

It's just a lot cleaner than:

var doubleValue = 0;
if (double.TryParse(numberAsString, out doubleValue)) {
    //whatever you want to do with doubleValue
}

I made a couple extension methods for these cases:

Extension method one

public static bool IsParseableAs<TInput>(this string value) {
    var type = typeof(TInput);

    var tryParseMethod = type.GetMethod("TryParse", BindingFlags.Static | BindingFlags.Public, Type.DefaultBinder,
        new[] { typeof(string), type.MakeByRefType() }, null);
    if (tryParseMethod == null) return false;

    var arguments = new[] { value, Activator.CreateInstance(type) };
    return (bool) tryParseMethod.Invoke(null, arguments);
}

Example:

"123".IsParseableAs<double>() ? double.Parse(sNumber) : 0;

Because IsParseableAs() tries to parse the string as the appropriate type instead of just checking if the string is "numeric" it should be pretty safe. And you can even use it for non numeric types that have a TryParse() method, like DateTime.

The method uses reflection and you end up calling the TryParse() method twice which, of course, isn't as efficient, but not everything has to be fully optimized, sometimes convenience is just more important.

This method can also be used to easily parse a list of numeric strings into a list of double or some other type with a default value without having to catch any exceptions:

var sNumbers = new[] {"10", "20", "30"};
var dValues = sNumbers.Select(s => s.IsParseableAs<double>() ? double.Parse(s) : 0);

Extension method two

public static TOutput ParseAs<TOutput>(this string value, TOutput defaultValue) {
    var type = typeof(TOutput);

    var tryParseMethod = type.GetMethod("TryParse", BindingFlags.Static | BindingFlags.Public, Type.DefaultBinder,
        new[] { typeof(string), type.MakeByRefType() }, null);
    if (tryParseMethod == null) return defaultValue;

    var arguments = new object[] { value, null };
    return ((bool) tryParseMethod.Invoke(null, arguments)) ? (TOutput) arguments[1] : defaultValue;
}

This extension method lets you parse a string as any type that has a TryParse() method and it also lets you specify a default value to return if the conversion fails.

This is better than using the ternary operator with the extension method above as it only does the conversion once. It still uses reflection though...

Examples:

"123".ParseAs<int>(10);
"abc".ParseAs<int>(25);
"123,78".ParseAs<double>(10);
"abc".ParseAs<double>(107.4);
"2014-10-28".ParseAs<DateTime>(DateTime.MinValue);
"monday".ParseAs<DateTime>(DateTime.MinValue);

Outputs:

123
25
123,78
107,4

QRGen is a good library that creates a layer on top of ZXing and makes QR Code generation in Java a piece of cake.

How abt something like this, using the standard bitset ...

#include <bitset> 
#include <iostream> 

template <std::size_t N> 
inline void 
rotate(std::bitset<N>& b, unsigned m) 
{ 
   b = b << m | b >> (N-m); 
} 

int main() 
{ 
   std::bitset<8> b(15); 
   std::cout << b << '\n'; 
   rotate(b, 2); 
   std::cout << b << '\n'; 

   return 0;
}

HTH,

The URL is relative to the location of the CSS file, so this should work for you:

url('../../images/image.jpg')

The relative URL goes two folders back, and then to the images folder - it should work for both cases, as long as the structure is the same.

From https://www.w3.org/TR/CSS1/#url:

Partial URLs are interpreted relative to the source of the style sheet, not relative to the document

I guess you mean this:

class Value:
    def __init__(self, v=None):
        self.v = v

v1 = Value(1)
v2 = Value(2)

d = {'a': v1, 'b': v1, 'c': v2, 'd': v2}
d['a'].v += 1

d['b'].v == 2 # True

• Python's strings and numbers are immutable objects,
• So, if you want d['a'] and d['b'] to point to the same value that "updates" as it changes, make the value refer to a mutable object (user-defined class like above, or a dict, list, set).
• Then, when you modify the object at d['a'], d['b'] changes at same time because they both point to same object.

<input type="file" onchange="getBaseUrl()">

function getBaseUrl ()  {
    var file = document.querySelector('input[type=file]')['files'][0];
    var reader = new FileReader();
    var baseString;
    reader.onloadend = function () {
        baseString = reader.result;
        console.log(baseString); 
    };
    reader.readAsDataURL(file);
}

To set value

 $('#searchField').val('your_value');

to retrieve value

$('#searchField').val();

Iterable is a generic interface. A problem you might be having (you haven't actually said what problem you're having, if any) is that if you use a generic interface/class without specifying the type argument(s) you can erase the types of unrelated generic types within the class. An example of this is in Non-generic reference to generic class results in non-generic return types.

So I would at least change it to:

public class ProfileCollection implements Iterable<Profile> { 
    private ArrayList<Profile> m_Profiles;

    public Iterator<Profile> iterator() {        
        Iterator<Profile> iprof = m_Profiles.iterator();
        return iprof; 
    }

    ...

    public Profile GetActiveProfile() {
        return (Profile)m_Profiles.get(m_ActiveProfile);
    }
}

and this should work:

for (Profile profile : m_PC) {
    // do stuff
}

Without the type argument on Iterable, the iterator may be reduced to being type Object so only this will work:

for (Object profile : m_PC) {
    // do stuff
}

This is a pretty obscure corner case of Java generics.

If not, please provide some more info about what's going on.

A while loop will always evaluate the condition first.

while (condition) {
  //gets executed after condition is checked
}

A do/while loop will always execute the code in the do{} block first and then evaluate the condition.

do {
  //gets executed at least once
} while (condition); 

A for loop allows you to initiate a counter variable, a check condition, and a way to increment your counter all in one line.

for (int x = 0; x < 100; x++) {
   //executed until x >= 100
}

At the end of the day, they are all still loops, but they offer some flexibility as to how they are executed.

Here is a great explanation of the reasoning behind the use of each different type of loop that may help clear things up. Thanks clyfe

The main difference between the for's and the while's is a matter of pragmatics: we usually use for when there is a known number of iterations, and use while constructs when the number of iterations in not known in advance. The while vs do ... while issue is also of pragmatics, the second executes the instructions once at start, and afterwards it behaves just like the simple while.

For loops are especially nice because they are concise. In order for this for loop:

for (int x = 0; x < 100; x++) {
   //executed until x >= 100
}

to be written as a while loop, you'd have to do the following:

int count = 0;
while (count < 100) {
  //do stuff
  count++;
}

In this case, there's just more stuff to keep up with and the count++; could get lost in the logic. This could end up being troublesome depending on where count gets incremented, and whether or not it should get incremented before or after the loop's logic. With a for loop, your counter variable is always incremented before the next iteration of the loop, which adds some uniformity to your code.

For the sake of completeness, it's probably meaningful to talk about break and continue statements here which come in handy when doing loop processing.

break will instantly terminate the current loop and no more iterations will be executed.

//will only run "do stuff" twice
for (int x = 0; x < 100; x++) {
  if (x == 2) {
    break;
  }
  //do stuff
}

continue will terminate the current iteration and move on to the next one.

//will run "do stuff" until x >= 100 except for when x = 2
for (int x = 0; x < 100; x++) {
  if (x == 2) {
    continue;
  }
  //do stuff
}

Note that in a for loop, continue evaluates the part3 expression of for (part1; part2; part3); in contrast, in a while loop, it just jumps to re-evaluate the loop condition.

Thanks Notable1, works for me with the tidytextr Create a dataframe with the name of files in one column and content in other.

    diretorio <- "D:/base"
    arquivos <- list.files(diretorio, pattern = "*.PDF")
    quantidade <- length(arquivos)

#
df = NULL
for (k in 1:quantidade) {

      nome = arquivos[k]
      print(nome)
      Sys.sleep(1) 
      dados = read_pdf(arquivos[k],ocr = T)
      print(dados)
      Sys.sleep(1)
      df = rbind(df, data.frame(nome,dados))
      Sys.sleep(1)
}
Encoding(df$text) <- "UTF-8"

The solution of @bunji works for me, but default options don't always give a good result. I added some useful parameter to tweak the appearance of the table.

import pandas as pd
import matplotlib.pyplot as plt
from pandas.tools.plotting import table
import numpy as np

dates = pd.date_range('20130101',periods=6)
df = pd.DataFrame(np.random.randn(6,4),index=dates,columns=list('ABCD'))

df.index = [item.strftime('%Y-%m-%d') for item in df.index] # Format date

fig, ax = plt.subplots(figsize=(12, 2)) # set size frame
ax.xaxis.set_visible(False)  # hide the x axis
ax.yaxis.set_visible(False)  # hide the y axis
ax.set_frame_on(False)  # no visible frame, uncomment if size is ok
tabla = table(ax, df, loc='upper right', colWidths=[0.17]*len(df.columns))  # where df is your data frame
tabla.auto_set_font_size(False) # Activate set fontsize manually
tabla.set_fontsize(12) # if ++fontsize is necessary ++colWidths
tabla.scale(1.2, 1.2) # change size table
plt.savefig('table.png', transparent=True)

The result:

default.css should be available at http://localhost:3001/default.css

The styles in app.use(express.static(__dirname + '/styles')); just tells express to look in the styles directory for a static file to serve. It doesn't (confusingly) then form part of the path it is available on.

SELECT DISTINCT (t1.ProdId), t1.Quantity FROM Dummy t1 INNER JOIN
       (SELECT ProdId, MAX(Quantity) as MaxQuantity FROM Dummy GROUP BY ProdId) t2
    ON t1.ProdId = t2.ProdId
   AND t1.Quantity = t2.MaxQuantity
 ORDER BY t1.ProdId

this will give you the idea.

You should use the StringFormat on the Binding. You can use either standard string formats, or custom string formats:

<TextBox Text="{Binding Value, StringFormat=N2}" />
<TextBox Text="{Binding Value, StringFormat={}{0:#,#.00}}" />

Note that the StringFormat only works when the target property is of type string. If you are trying to set something like a Content property (typeof(object)), you will need to use a custom StringFormatConverter (like here), and pass your format string as the ConverterParameter.

Edit for updated question

So, if your ViewModel defines the precision, I'd recommend doing this as a MultiBinding, and creating your own IMultiValueConverter. This is pretty annoying in practice, to go from a simple binding to one that needs to be expanded out to a MultiBinding, but if the precision isn't known at compile time, this is pretty much all you can do. Your IMultiValueConverter would need to take the value, and the precision, and output the formatted string. You'd be able to do this using String.Format.

However, for things like a ContentControl, you can much more easily do this with a Style:

<Style TargetType="{x:Type ContentControl}">
    <Setter Property="ContentStringFormat" 
            Value="{Binding Resolution, StringFormat=N{0}}" />
</Style>

Any control that exposes a ContentStringFormat can be used like this. Unfortunately, TextBox doesn't have anything like that.

Multiple mounts inside a folder

An additional reason could be a secondary mount inside your primary mount folder, e.g. after you worked on an SD card for an embedded device:

# mount /dev/sdb2 /mnt       # root partition which contains /boot
# mount /dev/sdb1 /mnt/boot  # boot partition

Unmounting /mnt will fail:

# umount /mnt
umount: /mnt: target is busy.

First we have to unmount the boot folder and then the root:

# umount /mnt/boot
# umount /mnt

BLOB :

BLOB (Binary Large Object) is a large object data type in the database system. BLOB could store a large chunk of data, document types and even media files like audio or video files. BLOB fields allocate space only whenever the content in the field is utilized. BLOB allocates spaces in Giga Bytes.

USAGE OF BLOB :

You can write a binary large object (BLOB) to a database as either binary or character data, depending on the type of field at your data source. To write a BLOB value to your database, issue the appropriate INSERT or UPDATE statement and pass the BLOB value as an input parameter. If your BLOB is stored as text, such as a SQL Server text field, you can pass the BLOB as a string parameter. If the BLOB is stored in binary format, such as a SQL Server image field, you can pass an array of type byte as a binary parameter.

I had to change my values/styles.xml to

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">

Before that change, it was without 'Base'.

Above answer can be considered to be confusing a little. String methods are not modifying original object. They return new object. It must be:

var str = "Sonic Free Games";
str = str.replace(/\s+/g, '-').toLowerCase(); //new object assigned to var str

5 years have passed and this essential requirement didn't get ignored by the Chrome devs.
While they offer no method to edit the data like in Firefox, they offer a full XHR replay.
This allows to debug ajax calls.

"Replay XHR" will repeat the entire transmission.

I found James Wald's answer the closest to my solution, except instead of "File->Import->General->Existing Projects into Workspace" (which did not work for me at all) I used "File->Import->Android->Existing Android Code Into Workspace". I am using Helios, maybe your version of Eclipse does not have this quirk.

NA is a special value in R, do not mix up the NA value with the "NA" string. Depending on the way the data was imported, your "NA" and "NULL" cells may be of various type (the default behavior is to convert "NA" strings to NA values, and let "NULL" strings as is).

If using read.table() or read.csv(), you should consider the "na.strings" argument to do clean data import, and always work with real R NA values.

An example, working in both cases "NULL" and "NA" cells :

DF <- read.csv("file.csv", na.strings=c("NA", "NULL"))
new_DF <- subset(DF, is.na(DF$Var2))

You can access the groups simply through the groups attribute on User.

from django.contrib.auth.models import User, Group

group = Group(name = "Editor")
group.save()                    # save this new group for this example
user = User.objects.get(pk = 1) # assuming, there is one initial user 
user.groups.add(group)          # user is now in the "Editor" group

then user.groups.all() returns [<Group: Editor>].

Alternatively, and more directly, you can check if a a user is in a group by:

if django_user.groups.filter(name = groupname).exists():

    ...

Note that groupname can also be the actual Django Group object.

Use ifelse:

frame$twohouses <- ifelse(frame$data>=2, 2, 1)
frame
   data twohouses
1     0         1
2     1         1
3     2         2
4     3         2
5     4         2
...
16    0         1
17    2         2
18    1         1
19    2         2
20    0         1
21    4         2

The difference between if and ifelse:

• if is a control flow statement, taking a single logical value as an argument
• ifelse is a vectorised function, taking vectors as all its arguments.

The help page for if, accessible via ?"if" will also point you to ?ifelse

According to this, you need to assign a height to the element in which the div is contained in order for 100% height to work. Does that work for you?

Taken from the ReactKonvaCore.d.ts file:

onClick?(evt: Konva.KonvaEventObject<MouseEvent>): void;

So, I'd say your event type is Konva.KonvaEventObject<MouseEvent>

to read first line using bash, use read statement. eg

read -r firstline<file

firstline will be your variable (No need to assign to another)

You can try like this:
yourArray.shift()

1. UNIQUE constraint (of which a PRIMARY KEY constraint is a variant). Checks that all values of a given field are unique across the table. This is X-axis constraint (records)

2. CHECK constraint (of which a NOT NULL constraint is a variant). Checks that a certain condition holds for the expression over the fields of the same record. This is Y-axis constraint (fields)

3. FOREIGN KEY constraint. Checks that a field's value is found among the values of a field in another table. This is Z-axis constraint (tables).

I do not believe you can set the style programatically. To get around this you can create a template layout xml file with the style assigned, for example in res/layout create tvtemplate.xml as with the following content:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="This is a template"
        style="@style/my_style" />

then inflate this to instantiate your new TextView:

TextView myText = (TextView)getLayoutInflater().inflate(R.layout.tvtemplate, null);

Hope this helps.

From ggplot2 2.0.0 you can use the margin = argument of element_text() to change the distance between the axis title and the numbers. Set the values of the margin on top, right, bottom, and left side of the element.

ggplot(mpg, aes(cty, hwy)) + geom_point()+
  theme(axis.title.y = element_text(margin = margin(t = 0, r = 20, b = 0, l = 0)))

margin can also be used for other element_text elements (see ?theme), such as axis.text.x, axis.text.y and title.

addition

in order to set the margin for axis titles when the axis has a different position (e.g., with scale_x_...(position = "top"), you'll need a different theme setting - e.g. axis.title.x.top. See https://github.com/tidyverse/ggplot2/issues/4343.

You could use this code:

abc_KeyDown(abc, new KeyEventArgs(Keys.Enter));

OP here (I am answering this question after two years, the post made by Daniel Cerecedo was not bad at a time, but the web services are developing very fast)

After three years of full-time software development (with focus also on software architecture, project management and microservice architecture) I definitely choose the second way (but with one general endpoint) as the best one.

If you have a special endpoint for images, it gives you much more power over handling those images.

We have the same REST API (Node.js) for both - mobile apps (iOS/android) and frontend (using React). This is 2017, therefore you don't want to store images locally, you want to upload them to some cloud storage (Google cloud, s3, cloudinary, ...), therefore you want some general handling over them.

Our typical flow is, that as soon as you select an image, it starts uploading on background (usually POST on /images endpoint), returning you the ID after uploading. This is really user-friendly, because user choose an image and then typically proceed with some other fields (i.e. address, name, ...), therefore when he hits "send" button, the image is usually already uploaded. He does not wait and watching the screen saying "uploading...".

The same goes for getting images. Especially thanks to mobile phones and limited mobile data, you don't want to send original images, you want to send resized images, so they do not take that much bandwidth (and to make your mobile apps faster, you often don't want to resize it at all, you want the image that fits perfectly into your view). For this reason, good apps are using something like cloudinary (or we do have our own image server for resizing).

Also, if the data are not private, then you send back to app/frontend just URL and it downloads it from cloud storage directly, which is huge saving of bandwidth and processing time for your server. In our bigger apps there are a lot of terabytes downloaded every month, you don't want to handle that directly on each of your REST API server, which is focused on CRUD operation. You want to handle that at one place (our Imageserver, which have caching etc.) or let cloud services handle all of it.

Cons : The only "cons" which you should think of is "not assigned images". User select images and continue with filling other fields, but then he says "nah" and turn off the app or tab, but meanwhile you successfully uploaded the image. This means you have uploaded an image which is not assigned anywhere.

There are several ways of handling this. The most easiest one is "I don't care", which is a relevant one, if this is not happening very often or you even have desire to store every image user send you (for any reason) and you don't want any deletion.

Another one is easy too - you have CRON and i.e. every week and you delete all unassigned images older than one week.

The CURL extension ext/curl is not installed or enabled in your PHP installation. Check the manual for information on how to install or enable CURL on your system.

If you want to use LinearLayout, you can do alignment with layout_weight with Space element.

E.g. following layout places textView and textView2 next to each other and textView3 will be right-aligned

<LinearLayout
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:text="Medium Text"
        android:id="@+id/textView" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:text="Medium Text"
        android:id="@+id/textView2" />

    <Space
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="20dp" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:text="Medium Text"
        android:id="@+id/textView3" />
</LinearLayout>

you can achieve the same effect without Space if you would set layout_weight to textView2. It's just that I like things more separated, plus to demonstrate Space element.

    <TextView
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:text="Medium Text"
        android:id="@+id/textView2" />

Note that you should (not must though) set layout_width explicitly as it will be recalculated according to it's weight anyway (same way you should set height in elements of vertical LinearLayout). For other layout performance tips see Android Layout Tricks series.

If you are using maven, try adding Lombok path to maven-compiler-plugin list of annotation processor as shown below.

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <annotationProcessorPaths>
                    <path>
                        <groupId>org.mapstruct</groupId>
                        <artifactId>mapstruct-processor</artifactId>
                        <version>1.3.0.Final</version>
                    </path>
                    <path>
                        <groupId>org.projectlombok</groupId>
                        <artifactId>lombok</artifactId>
                        <version>1.18.10</version>
                    </path>
                </annotationProcessorPaths>
            </configuration>
        </plugin>

Change the version as per your version of Lombok. Other than that ensure you have done the following

• installed the Lombok plugin for Intellij.
• Enabled annotation processing for your project under File -> Settings -> Build, Execution, Deployment -> Compiler -> Annotation Processor. For me both, Obtain processors from project classpath and Processor path is working. So not sure what will work for you, but try whichever works.

And rather than shooting in the dark for hours. Reading a little bit how annotation processors work and are used by compiler may help. so have quick read below.

Using PropertyInfo of the System.Reflection namespace. Reflection compiles just fine no matter what property we try to access. The error will come up during run-time.

    public static object GetObjProperty(object obj, string property)
    {
        Type t = obj.GetType();
        PropertyInfo p = t.GetProperty("Location");
        Point location = (Point)p.GetValue(obj, null);
        return location;
    }

It works fine to get the Location property of an object

Label1.Text = GetObjProperty(button1, "Location").ToString();

We'll get the Location : {X=71,Y=27} We can also return location.X or location.Y on the same way.

Sure you just need to setup a local web server. Check out XAMPP: http://www.apachefriends.org/en/xampp.html

That will get you up and running in about 10 minutes.

There is now a way to run php locally without installing a server: https://stackoverflow.com/a/21872484/672229

Yes but the files need to be processed. For example you can install test servers like mamp / lamp / wamp depending on your plateform.

Basically you need apache / php running.

I assume you want to know the performance difference between the following:

WHERE foo IN ('a', 'b', 'c')
WHERE foo = 'a' OR foo = 'b' OR foo = 'c'

According to the manual for MySQL if the values are constant IN sorts the list and then uses a binary search. I would imagine that OR evaluates them one by one in no particular order. So IN is faster in some circumstances.

The best way to know is to profile both on your database with your specific data to see which is faster.

I tried both on a MySQL with 1000000 rows. When the column is indexed there is no discernable difference in performance - both are nearly instant. When the column is not indexed I got these results:

SELECT COUNT(*) FROM t_inner WHERE val IN (1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000);
1 row fetched in 0.0032 (1.2679 seconds)

SELECT COUNT(*) FROM t_inner WHERE val = 1000 OR val = 2000 OR val = 3000 OR val = 4000 OR val = 5000 OR val = 6000 OR val = 7000 OR val = 8000 OR val = 9000;
1 row fetched in 0.0026 (1.7385 seconds)

So in this case the method using OR is about 30% slower. Adding more terms makes the difference larger. Results may vary on other databases and on other data.
