I had issue while inspecting the xml file in notepad++ and saving the file, though I had the top utf-8 xml tag as <?xml version="1.0" encoding="utf-8"?>

Got fixed by saving the file in notpad++ with Encoding(Tab) > Encode in UTF-8:selected (was Encode in UTF-8-BOM)

The correct answer is "python collections do not have a foreach". In native python we need to resort to the external for _element_ in _collection_ syntax which is not what the OP is after.

Python is in general quite weak for functionals programming. There are a few libraries to mitigate a bit. I helped author one of these infixpy https://pypi.org/project/infixpy/

from infixpy import Seq
(Seq([1,2,3]).foreach(lambda x: print(x)))

If the default value of string were the empty string, I would not have to test

Wrong! Changing the default value doesn't change the fact that it's a reference type and someone can still explicitly set the reference to be null.

Additionally Nullable<String> would make sense.

True point. It would make more sense to not allow null for any reference types, instead requiring Nullable<TheRefType> for that feature.

So why did the designers of C# choose to use null as the default value of strings?

Consistency with other reference types. Now, why allow null in reference types at all? Probably so that it feels like C, even though this is a questionable design decision in a language that also provides Nullable.

Here's an example of using prepend to add a paragraph to the document.

var element = document.createElement("p");
var text = document.createTextNode("Example text");
element.appendChild(text);
document.body.prepend(element);

result:

<p>Example text</p>

Nobody here seems to have mentioned it yet, so let me give an example in Python 3.6's f-string/template-string format, which I think is beautifully neat:

>>> f'{a:.2f}'

It works well with longer examples too, with operators and not needing parens:

>>> print(f'Completed in {time.time() - start:.2f}s')

Here's a variation of Oscar's first version that doesn't use a for-each loop.

for (int i = 0; i < charArray.length; i++) {
    if (charArray[i] == 'q') {
        // do something
        break;
    }
}

You could have a boolean variable that gets set to false before the loop, then make "do something" set the variable to true, which you could test for after the loop. The loop could also be wrapped in a function call then just use 'return true' instead of the break, and add a 'return false' statement after the for loop.

We encountered this error today. This is how we debugged and fixed it.

1. Package went to invalid state due to this error ORA-01775.

2. With the error line number , We went thru the package body code and found the code which was trying to insert data into a table.

3. We ran below queries to check if the above table and synonym exists.

   SELECT * FROM DBA_TABLES WHERE TABLE_NAME = '&TABLE_NAME';  -- No rows returned
   
   SELECT * FROM DBA_SYNONYMS WHERE SYNONYM_NAME = '&SYNONYM_NAME'; -- 1 row returned
   

4. With this we concluded that the table needs to be re- created. As the synonym was pointing to a table that did not exist.

5. DBA team re-created the table and this fixed the issue.

Create a file, a.py:

print(__name__) # It will print out __main__

__name__ is always equal to __main__ whenever that file is run directly showing that this is the main file.

Create another file, b.py, in the same directory:

import a  # Prints a

Run it. It will print a, i.e., the name of the file which is imported.

So, to show two different behavior of the same file, this is a commonly used trick:

# Code to be run when imported into another python file

if __name__ == '__main__':
    # Code to be run only when run directly

Just add in: border-bottom: none;

#index-03 {
    position:absolute;
    border: .1px solid #900;
    border-bottom: none;
    left:0px;
    top:102px;
    width:900px;
    height:27px;
}

Facelets is a XML based view technology. The & is a special character in XML representing the start of an entity like & which ends with the ; character. You'd need to either escape it, which is ugly:

rendered="#{beanA.prompt == true && beanB.currentBase != null}"

or to use the and keyword instead, which is preferred as to readability and maintainability:

rendered="#{beanA.prompt == true and beanB.currentBase != null}"

See also:

• Java EE 6 tutorial - Operators in EL

Unrelated to the concrete problem, comparing booleans with booleans makes little sense when the expression expects a boolean outcome already. I'd get rid of == true:

rendered="#{beanA.prompt and beanB.currentBase != null}"

This was my solution:

this.myForm = this._formBuilder.group({
    socDate: [[{ value: '', disabled: true }], Validators.required],
    ...
)}

<input fxFlex [matDatepicker]="picker" placeholder="Select Date" formControlName="socDate" [attr.disabled]="true" />

Option 1 Faster Than Option 2

Because Option 2 creates a new List reference, and then creates an n element array from the List (option 1 perfectly sizes the output array). However, first you need to fix the off by one bug. Use < (not <=). Like,

String[] out = new String[n];
for(int i = 0; i < n; i++) {
    out[i] = in.get(i);
}

If your application always uses the same port, you can kill all the processes in that port like this.

kill -9 $(lsof -t -i:8080)

select t.data_type 
  from user_tab_columns t 
 where t.TABLE_NAME = 'xxx' 
   and t.COLUMN_NAME='aaa'

(char)myint;

for example:

Console.WriteLine("(char)122 is {0}", (char)122);

yields:

(char)122 is z

It's simple. Do this, in your Manifest file.

<activity
    android:name="Your app name"
    android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.HOME" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
</activity>

I believe this is the fastest query that answers your question, because it doesn't use an interpreted $where clause:

{$nor: [
    {name: {$exists: false}},
    {name: {$size: 0}},
    {name: {$size: 1}}
]}

It means "all documents except those without a name (either non existant or empty array) or with just one name."

Test:

> db.test.save({})
> db.test.save({name: []})
> db.test.save({name: ['George']})
> db.test.save({name: ['George', 'Raymond']})
> db.test.save({name: ['George', 'Raymond', 'Richard']})
> db.test.save({name: ['George', 'Raymond', 'Richard', 'Martin']})
> db.test.find({$nor: [{name: {$exists: false}}, {name: {$size: 0}}, {name: {$size: 1}}]})
{ "_id" : ObjectId("511907e3fb13145a3d2e225b"), "name" : [ "George", "Raymond" ] }
{ "_id" : ObjectId("511907e3fb13145a3d2e225c"), "name" : [ "George", "Raymond", "Richard" ] }
{ "_id" : ObjectId("511907e3fb13145a3d2e225d"), "name" : [ "George", "Raymond", "Richard", "Martin" ] }
>

Either do it with CSS like the other answers did or change the text style color directly via the onMouseOver and onMouseOut event:

onmouseover="this.bgColor='white'; this.style.color='black'"

onmouseout="this.bgColor='black'; this.style.color='white'"

I have written a quick example to demonstrate how to create a layout programmatically.

public class CodeLayout extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Creating a new RelativeLayout
        RelativeLayout relativeLayout = new RelativeLayout(this);

        // Defining the RelativeLayout layout parameters.
        // In this case I want to fill its parent
        RelativeLayout.LayoutParams rlp = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.FILL_PARENT,
                RelativeLayout.LayoutParams.FILL_PARENT);

        // Creating a new TextView
        TextView tv = new TextView(this);
        tv.setText("Test");

        // Defining the layout parameters of the TextView
        RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.WRAP_CONTENT,
                RelativeLayout.LayoutParams.WRAP_CONTENT);
        lp.addRule(RelativeLayout.CENTER_IN_PARENT);

        // Setting the parameters on the TextView
        tv.setLayoutParams(lp);

        // Adding the TextView to the RelativeLayout as a child
        relativeLayout.addView(tv);

        // Setting the RelativeLayout as our content view
        setContentView(relativeLayout, rlp);
    }
}

In theory everything should be clear as it is commented. If you don't understand something just tell me.

if you are adding multiple items to the list use this:

mAdapter.notifyItemRangeInserted(startPosition, itemcount);

This notify any registered observers that the currently reflected itemCount items starting at positionStart have been newly inserted. The item previously located at positionStart and beyond can now be found starting at position positinStart+itemCount

existing item in the dataset still considered up to date.

You might want to push the object into the array

enter code here

var AssocArray = new Array();

AssocArray.push( "The letter A");

console.log("a = " + AssocArray[0]);

// result: "a = The letter A"

console.log( AssocArray[0]);

JSON.stringify(AssocArray);

Yes it makes sense to use requireJS with Angular, I spent several days to test several technical solutions.

I made an Angular Seed with RequireJS on Server Side. Very simple one. I use SHIM notation for no AMD module and not AMD because I think it's very difficult to deal with two different Dependency injection system.

I use grunt and r.js to concatenate js files on server depends on the SHIM configuration (dependency) file. So I refer only one js file in my app.

For more information go on my github Angular Seed : https://github.com/matohawk/angular-seed-requirejs

It is a good practice to set where the access log should be in nginx configuring file . Using acces_log /path/ Like this.

keyval $remote_addr:$http_user_agent $seen zone=clients;

server { listen 443 ssl;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers   HIGH:!aNULL:!MD5;

if ($seen = "") {
    set $seen  1;
    set $logme 1;
}
access_log  /tmp/sslparams.log sslparams if=$logme;
error_log  /pathtolog/error.log;
# ...
}

This generally happens only when you are not controlling the value of the filed when the application started and after some event or some function fired or the state changed, you are now trying to control the value in input field.

This transition of not having control over the input and then having control over it is what causes the issue to happen in the first place.

The best way to avoid this is by declaring some value for the input in the constructor of the component. So that the input element has value from the start of the application.

You actually can't manually "free" memory in C, in the sense that the memory is released from the process back to the OS ... when you call malloc(), the underlying libc-runtime will request from the OS a memory region. On Linux, this may be done though a relatively "heavy" call like mmap(). Once this memory region is mapped to your program, there is a linked-list setup called the "free store" that manages this allocated memory region. When you call malloc(), it quickly looks though the free-store for a free block of memory at the size requested. It then adjusts the linked list to reflect that there has been a chunk of memory taken out of the originally allocated memory pool. When you call free() the memory block is placed back in the free-store as a linked-list node that indicates its an available chunk of memory.

If you request more memory than what is located in the free-store, the libc-runtime will again request more memory from the OS up to the limit of the OS's ability to allocate memory for running processes. When you free memory though, it's not returned back to the OS ... it's typically recycled back into the free-store where it can be used again by another call to malloc(). Thus, if you make a lot of calls to malloc() and free() with varying memory size requests, it could, in theory, cause a condition called "memory fragmentation", where there is enough space in the free-store to allocate your requested memory block, but not enough contiguous space for the size of the block you've requested. Thus the call to malloc() fails, and you're effectively "out-of-memory" even though there may be plenty of memory available as a total amount of bytes in the free-store.

If you are forcing www. in url or forcing ssl prototcol, then try to use possible variations in htaccess file, such as:

RewriteEngine On
RewriteBase /

### Force WWW ###

RewriteCond %{HTTP_HOST} ^example\.com
RewriteRule (.*) http://www.example.com/$1 [R=301,L]

## Force SSL ###

RewriteCond %{SERVER_PORT} 80 
RewriteRule ^(.*)$ https://example.com/$1 [R,L]

## Block  IP's ###
Order Deny,Allow
Deny from 256.251.0.139
Deny from 199.127.0.259

I'd like to complement Angry Shoe's and peterchen's excellent answers with a short overview of the state of the art in 2015:

Some good choices

randutils

The randutils library (presentation) is an interesting novelty, offering a simple interface and (declared) robust random capabilities. It has the disadvantages that it adds a dependence on your project and, being new, it has not been extensively tested. Anyway, being free (MIT license) and header-only, I think it's worth a try.

Minimal sample: a die roll

#include <iostream>
#include "randutils.hpp"
int main() {
    randutils::mt19937_rng rng;
    std::cout << rng.uniform(1,6) << "\n";
}

Even if one is not interested in the library, the website (http://www.pcg-random.org/) provides many interesting articles about the theme of random number generation in general and the C++ library in particular.

Boost.Random

Boost.Random (documentation) is the library which inspired C++11's <random>, with whom shares much of the interface. While theoretically also being an external dependency, Boost has by now a status of "quasi-standard" library, and its Random module could be regarded as the classical choice for good-quality random number generation. It features two advantages with respect to the C++11 solution:

• it is more portable, just needing compiler support for C++03
• its random_device uses system-specific methods to offer seeding of good quality

The only small flaw is that the module offering random_device is not header-only, one has to compile and link boost_random.

Minimal sample: a die roll

#include <iostream>
#include <boost/random.hpp>
#include <boost/nondet_random.hpp>

int main() {
    boost::random::random_device                  rand_dev;
    boost::random::mt19937                        generator(rand_dev());
    boost::random::uniform_int_distribution<>     distr(1, 6);

    std::cout << distr(generator) << '\n';
}

While the minimal sample does its work well, real programs should use a pair of improvements:

• make mt19937 a thread_local: the generator is quite plump (> 2 KB) and is better not allocated on the stack
• seed mt19937 with more than one integer: the Mersenne Twister has a big state and can take benefit of more entropy during initialization

Some not-so-good choices

The C++11 library

While being the most idiomatic solution, the <random> library does not offer much in exchange for the complexity of its interface even for the basic needs. The flaw is in std::random_device: the Standard does not mandate any minimal quality for its output (as long as entropy() returns 0) and, as of 2015, MinGW (not the most used compiler, but hardly an esoterical choice) will always print 4 on the minimal sample.

Minimal sample: a die roll

#include <iostream>
#include <random>
int main() {
    std::random_device                  rand_dev;
    std::mt19937                        generator(rand_dev());
    std::uniform_int_distribution<int>  distr(1, 6);

    std::cout << distr(generator) << '\n';
}

If the implementation is not rotten, this solution should be equivalent to the Boost one, and the same suggestions apply.

Godot's solution

Minimal sample: a die roll

#include <iostream>
#include <random>

int main() {
    std::cout << std::randint(1,6);
}

This is a simple, effective and neat solution. Only defect, it will take a while to compile – about two years, providing C++17 is released on time and the experimental randint function is approved into the new Standard. Maybe by that time also the guarantees on the seeding quality will improve.

The worse-is-better solution

Minimal sample: a die roll

#include <cstdlib>
#include <ctime>
#include <iostream>

int main() {
    std::srand(std::time(nullptr));
    std::cout << (std::rand() % 6 + 1);
}

The old C solution is considered harmful, and for good reasons (see the other answers here or this detailed analysis). Still, it has its advantages: is is simple, portable, fast and honest, in the sense it is known that the random numbers one gets are hardly decent, and therefore one is not tempted to use them for serious purposes.

The accounting troll solution

Minimal sample: a die roll

#include <iostream>

int main() {
    std::cout << 9;   // http://dilbert.com/strip/2001-10-25
}

While 9 is a somewhat unusual outcome for a regular die roll, one has to admire the excellent combination of good qualities in this solution, which manages to be the fastest, simplest, most cache-friendly and most portable one. By substituting 9 with 4 one gets a perfect generator for any kind of Dungeons and Dragons die, while still avoiding the symbol-laden values 1, 2 and 3. The only small flaw is that, because of the bad temper of Dilbert's accounting trolls, this program actually engenders undefined behavior.

There are several ways to create a favicon. The best way for you depends on various factors:

• The time you can spend on this task. For many people, this is "as quick as possible".
• The efforts you are willing to make. Like, drawing a 16x16 icon by hand for better results.
• Specific constraints, like supporting a specific browser with odd specs.

First method: Use a favicon generator

If you want to get the job done well and quickly, you can use a favicon generator. This one creates the pictures and HTML code for all major desktop and mobiles browsers. Full disclosure: I'm the author of this site.

Advantages of such solution: it's quick and all compatibility considerations were already addressed for you.

Second method: Create a favicon.ico (desktop browsers only)

As you suggest, you can create a favicon.ico file which contains 16x16 and 32x32 pictures (note that Microsoft recommends 16x16, 32x32 and 48x48).

Then, declare it in your HTML code:

<link rel="shortcut icon" href="/path/to/icons/favicon.ico">

This method will work with all desktop browsers, old and new. But most mobile browsers will ignore the favicon.

About your suggestion of placing the favicon.ico file in the root and not declaring it: beware, although this technique works on most browsers, it is not 100% reliable. For example Windows Safari cannot find it (granted: this browser is somehow deprecated on Windows, but you get the point). This technique is useful when combined with PNG icons (for modern browsers).

Third method: Create a favicon.ico, a PNG icon and an Apple Touch icon (all browsers)

In your question, you do not mention the mobile browsers. Most of them will ignore the favicon.ico file. Although your site may be dedicated to desktop browsers, chances are that you don't want to ignore mobile browsers altogether.

You can achieve a good compatibility with:

• favicon.ico, see above.
• A 192x192 PNG icon for Android Chrome
• A 180x180 Apple Touch icon (for iPhone 6 Plus; other device will scale it down as needed).

Declare them with

<link rel="shortcut icon" href="/path/to/icons/favicon.ico">
<link rel="icon" type="image/png" href="/path/to/icons/favicon-192x192.png" sizes="192x192">
<link rel="apple-touch-icon" sizes="180x180" href="/path/to/icons/apple-touch-icon-180x180.png">

This is not the full story, but it's good enough in most cases.

You can use CAST function:

SELECT CAST(your_column_name AS varchar(10)) FROM your_table_name

do just

<dependency>
   <groupId>javax.el</groupId>
   <artifactId>javax.el-api</artifactId>
   <version>2.2.4</version>
</dependency>

Disclaimer: Everything below is only anecdotal and drawn directly from my personal experience. Anyone that feels up to conducting a more empirically rigorous analysis is welcome to carry it out and down vote if I'm. I am also aware that SQL is a declarative language and you're not supposed to have to consider HOW your code is processed when you write it, but, because I value my time, I do.

There are infinite logically equivalent statements, but I'll consider three(ish).

Case 1: Two Comparisons in a standard order (Evaluation order fixed)

A >= MinBound AND A <= MaxBound

Case 2: Syntactic sugar (Evaluation order is not chosen by author)

A BETWEEN MinBound AND MaxBound

Case 3: Two Comparisons in an educated order (Evaluation order chosen at write time)

A >= MinBound AND A <= MaxBound

Or

A <= MaxBound AND A >= MinBound

In my experience, Case 1 and Case 2 do not have any consistent or notable differences in performance as they are dataset ignorant.

However, Case 3 can greatly improve execution times. Specifically, if you're working with a large data set and happen to have some heuristic knowledge about whether A is more likely to be greater than the MaxBound or lesser than the MinBound you can improve execution times noticeably by using Case 3 and ordering the comparisons accordingly.

One use case I have is querying a large historical dataset with non-indexed dates for records within a specific interval. When writing the query, I will have a good idea of whether or not more data exists BEFORE the specified interval or AFTER the specified interval and can order my comparisons accordingly. I've had execution times cut by as much as half depending on the size of the dataset, the complexity of the query, and the amount of records filtered by the first comparison.

Ruby 1.9.2 and Rails 3 have an easy way to run one spec file:

  ruby -I spec spec/models/user_spec.rb

Explanation:

• ruby command tends to be faster than the rake command
• -I spec means "include the 'spec' directory when looking for files"
• spec/models/user_spec.rb is the file we want to run.

Simple solution for linux users, just add sudo in front of whatever command you're running for npm

Use the connection string below to read from an XLSX file:

string ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + <> + ";Extended Properties=Excel 8.0;";

The easiest way to solve this in pure HTML is to use the <base href="…"> element like so:

<base href="http://localhost/mywebsite/" />

Then all of the URLs in your HTML can just be this:

<a href="images/example.png">Link To Image</a>

Just change the <base href="…"> to match your server. The rest of the HTML paths will just fall in line and will be appended to that.

An abstract class can have implementations.

An interface doesn't have implementations, it simply defines a kind of contract.

There can also be some language-dependent differences: for example C# does not have multiple inheritance, but multiple interfaces can be implemented in a class.

After update to macOS 10.13.3

After updating do macOS 10.13, I had to install "Command Line Tools (macOS 10.13) for Xcode 9.3" downloaded from https://developer.apple.com/download/more/

for ((i=0; i<=1000; i++)); do
    echo "http://example.com/$i.jpg"
done

Not technically a list but similar to a list in terms of functionality and it's a fixed length

from collections import deque
my_deque_size_10 = deque(maxlen=10)

If it's full, ie got 10 items then adding another item results in item @index 0 being discarded. FIFO..but you can also append in either direction. Used in say

• a rolling average of stats
• piping a list through it aka sliding a window over a list until you get a match against another deque object.

If you need a list then when full just use list(deque object)

Sure you can.

ALTER TABLE myTable ALTER COLUMN myColumn int NULL

Just substitute int for whatever datatype your column is.

If anyone needs it, here is the same code snippet but for Xamarin.Android.

The -> is simply syntactic sugar for a pointer dereference,

As others have said:

pointer->method();

is a simple method of saying:

(*pointer).method();

I had the same problem and it seems that it is because of the background color of the button. Try changing the background color to another color eg:

android:background="@color/colorActive"

and see if it works. You can then define a style if you want for the button to use.

I was having the same problem until I read Jon Skeet's answer about the debugger displaying a single backslash with a double backslash even though the string may have a single backslash. I was not aware of that. So I changed my code from

text2 = text1.Replace(@"\\", @"/");

to

text2 = text1.Replace(@"\", @"/");

and that solved the problem. Note: I'm interfacing and R.Net which uses single forward slashes in path strings.

ArrayIndexOutOfBoundsException in simple words is -> you have 10 students in your class (int array size 10) and you want to view the value of the 11th student (a student who does not exist)

if you make this int i[3] then i takes values i[0] i[1] i[2]

for your problem try this code structure

double[] array = new double[50];

    for (int i = 0; i < 24; i++) {

    }

    for (int j = 25; j < 50; j++) {

    }

In code to load a resource in the executing assembly where my image Freq.png was in the folder Icons and defined as Resource:

this.Icon = new BitmapImage(new Uri(@"pack://application:,,,/" 
    + Assembly.GetExecutingAssembly().GetName().Name 
    + ";component/" 
    + "Icons/Freq.png", UriKind.Absolute)); 

I also made a function:

/// <summary>
/// Load a resource WPF-BitmapImage (png, bmp, ...) from embedded resource defined as 'Resource' not as 'Embedded resource'.
/// </summary>
/// <param name="pathInApplication">Path without starting slash</param>
/// <param name="assembly">Usually 'Assembly.GetExecutingAssembly()'. If not mentionned, I will use the calling assembly</param>
/// <returns></returns>
public static BitmapImage LoadBitmapFromResource(string pathInApplication, Assembly assembly = null)
{
    if (assembly == null)
    {
        assembly = Assembly.GetCallingAssembly();
    }

    if (pathInApplication[0] == '/')
    {
        pathInApplication = pathInApplication.Substring(1);
    }
    return new BitmapImage(new Uri(@"pack://application:,,,/" + assembly.GetName().Name + ";component/" + pathInApplication, UriKind.Absolute)); 
}

Usage (assumption you put the function in a ResourceHelper class):

this.Icon = ResourceHelper.LoadBitmapFromResource("Icons/Freq.png");

Note: see MSDN Pack URIs in WPF:
pack://application:,,,/ReferencedAssembly;component/Subfolder/ResourceFile.xaml

This is my solution...

My take on it...obviously, you've got to do something with the data you read in. If it involves writing it to the sheet, that'll be deadly slow with a normal For Loop. I came up with the following based upon a rehash of some of the items there, plus some help from the Chip Pearson website.

Reading in the text file (assuming you don't know the length of the range it will create, so only the startingCell is given):

Public Sub ReadInPlainText(startCell As Range, Optional textfilename As Variant)

   If IsMissing(textfilename) Then textfilename = Application.GetOpenFilename("All Files (*.*), *.*", , "Select Text File to Read")
   If textfilename = "" Then Exit Sub

   Dim filelength As Long
   Dim filenumber As Integer
   filenumber = FreeFile
   filelength = filelen(textfilename)
   Dim text As String
   Dim textlines As Variant

   Open textfilename For Binary Access Read As filenumber

   text = Space(filelength)
   Get #filenumber, , text

   'split the file with vbcrlf
   textlines = Split(text, vbCrLf) 

   'output to range
   Dim outputRange As Range
   Set outputRange = startCell
   Set outputRange = outputRange.Resize(UBound(textlines), 1)
   outputRange.Value = Application.Transpose(textlines)

   Close filenumber
 End Sub

Conversely, if you need to write out a range to a text file, this does it quickly in one print statement (note: the file 'Open' type here is in text mode, not binary..unlike the read routine above).

Public Sub WriteRangeAsPlainText(ExportRange As Range, Optional textfilename As Variant)
   If IsMissing(textfilename) Then textfilename = Application.GetSaveAsFilename(FileFilter:="Text Files (*.txt), *.txt")
   If textfilename = "" Then Exit Sub

   Dim filenumber As Integer
   filenumber = FreeFile
   Open textfilename For Output As filenumber

   Dim textlines() As Variant, outputvar As Variant

   textlines = Application.Transpose(ExportRange.Value)
   outputvar = Join(textlines, vbCrLf)
   Print #filenumber, outputvar
   Close filenumber
End Sub

This is an exact fix to your problem, but I would advise against initializing the matrix with a default value that represents '0' or 'undefined', as Arrays in javascript are just regular objects, so you wind up wasting effort. If you want to default the cells to some meaningful value, then this snippet will work well, but if you want an uninitialized matrix, don't use this version:

/**
* Generates a matrix (ie: 2-D Array) with: 
* 'm' columns, 
* 'n' rows, 
* every cell defaulting to 'd';
*/
function Matrix(m, n, d){
    var mat = Array.apply(null, new Array(m)).map(
        Array.prototype.valueOf,
        Array.apply(null, new Array(n)).map(
            function() {
               return d;
            }
        )
    );
    return mat;
}

Usage:

< Matrix(3,2,'dobon');
> Array [ Array['dobon', 'dobon'], Array['dobon', 'dobon'], Array['dobon', 'dobon'] ]

If you would rather just create an uninitialized 2-D Array, then this will be more efficient than unnecessarily initializing every entry:

/**
* Generates a matrix (ie: 2-D Array) with: 
* 'm' columns, 
* 'n' rows, 
* every cell remains 'undefined';
*/
function Matrix(m, n){
    var mat = Array.apply(null, new Array(m)).map(
        Array.prototype.valueOf,
        new Array(n)
    );
    return mat;
}

Usage:

< Matrix(3,2);
> Array [ Array[2], Array[2], Array[2] ]

What do you want to fade? The background or color attribute?

Currently you're changing the background color, but telling it to transition the color property. You can use all to transition all properties.

.clicker { 
    -moz-transition: all .2s ease-in;
    -o-transition: all .2s ease-in;
    -webkit-transition: all .2s ease-in;
    transition: all .2s ease-in;
    background: #f5f5f5; 
    padding: 20px;
}

.clicker:hover { 
    background: #eee;
}

Otherwise just use transition: background .2s ease-in.

You have not joined TableD, merely selected the TableD FIELD (dID) from one of the tables.

Create the column:

ALTER TABLE yourtable ADD COLUMN combined VARCHAR(50);

Update the current values:

UPDATE yourtable SET combined = CONCAT(zipcode, ' - ', city, ', ', state);

Update all future values automatically:

CREATE TRIGGER insert_trigger
BEFORE INSERT ON yourtable
FOR EACH ROW
SET new.combined = CONCAT(new.zipcode, ' - ', new.city, ', ', new.state);

CREATE TRIGGER update_trigger
BEFORE UPDATE ON yourtable
FOR EACH ROW
SET new.combined = CONCAT(new.zipcode, ' - ', new.city, ', ', new.state);

<meta name="language" content="Spanish">

This isn't defined in any specification (including the HTML5 draft)

<meta http-equiv="content-language" content="es">

This is a poor man's version of a real HTTP header and should really be expressed in the headers. For example:

Content-language: es
Content-type: text/html;charset=UTF-8

It says that the document is intended for Spanish language speakers (it doesn't, however mean the document is written in Spanish; it could, for example, be written in English as part of a language course for Spanish speakers).

From the spec:

The Content-Language entity-header field describes the natural language(s) of the intended audience for the enclosed entity. Note that this might not be equivalent to all the languages used within the entity-body.

If you want to state that a document is written in Spanish then use:

<html lang="es">

/usr/local/ssl/openssl.cnf

is soft link of

/etc/ssl/openssl.cnf

You can see that using long list (ls -l) on the /usr/local/ssl/ directory where you will find

lrwxrwxrwx 1 root root 20 Mar 1 05:15 openssl.cnf -> /etc/ssl/openssl.cnf

I would agree with @evillinux, It would be best to make your background image semi transparent so it supports < ie8

The other suggestions of using another div are also a great option, and it's the way to go if you want to do this in css. For example if the site had such features as selecting your own background color. I would suggest using a filter for older IE. eg:

filter:Alpha(opacity=50)

Double check your manifest, your first activity should have tag

    <intent-filter>
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>

inside of activity tag.

If that doesn't work, look for target build, which located in the left of run button (green-colored play button), it should be targeting "app" folder, not a particular activity. if it doesn't targeting "app", just click it and choose "app" from drop down list.

Hope it helps!

Update April 27, 2015

Up and coming to the HTML5 scene is the download attribute. It's supported in Firefox and Chrome, and soon to come to IE11. Depending on your needs, you could use it instead of an AJAX request (or using window.location) so long as the file you want to download is on the same origin as your site.

You could always make the AJAX request/window.location a fallback by using some JavaScript to test if download is supported and if not, switching it to call window.location.

Original answer

You can't have an AJAX request open the download prompt since you physically have to navigate to the file to prompt for download. Instead, you could use a success function to navigate to download.php. This will open the download prompt but won't change the current page.

$.ajax({
    url: 'download.php',
    type: 'POST',
    success: function() {
        window.location = 'download.php';
    }
});

Even though this answers the question, it's better to just use window.location and avoid the AJAX request entirely.

The macros defined in <inttypes.h> are the most correct way to print values of types uint32_t, uint16_t, and so forth -- but they're not the only way.

Personally, I find those macros difficult to remember and awkward to use. (Given the syntax of a printf format string, that's probably unavoidable; I'm not claiming I could have come up with a better system.)

An alternative is to cast the values to a predefined type and use the format for that type.

Types int and unsigned int are guaranteed by the language to be at least 16 bits wide, and therefore to be able to hold any converted value of type int16_t or uint16_t, respectively. Similarly, long and unsigned long are at least 32 bits wide, and long long and unsigned long long are at least 64 bits wide.

For example, I might write your program like this (with a few additional tweaks):

#include <stdio.h>
#include <stdint.h>
#include <netinet/in.h>  

int main(void)
{
    uint32_t a=12, a1;
    uint16_t b=1, b1;
    a1 = htonl(a);
    printf("%lu---------%lu\n", (unsigned long)a, (unsigned long)a1);
    b1 = htons(b);
    printf("%u-----%u\n", (unsigned)b, (unsigned)b1);
    return 0;
}

One advantage of this approach is that it can work even with pre-C99 implementations that don't support <inttypes.h>. Such an implementation most likely wouldn't have <stdint.h> either, but the technique is useful for other integer types.

There is another solution for testing APIs on development server.

• Set HTTP Basic Authentication only for web routes
• Leave all API routes free from authentication

Web server configuration for nginx and Laravel would be like this:

    location /api {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location / {
        try_files $uri $uri/ /index.php?$query_string;

        auth_basic "Enter password";
        auth_basic_user_file /path/to/.htpasswd;
    }

Authorization: Bearer will do the job of defending the development server against web crawlers and other unwanted visitors.

I don't like to use setTimeout in or even have strange temporary inputs. So I came up with this.

Simply change your password field type to text

<input name="password" type="text" value="">

And when the user focus that input change it again to password

$('input[name=password]').on('focus', function (e) {
    $(e.target).attr('type', 'password');
});

Its working using latest Chrome (Version 54.0.2840.71 (64-bit))

Just replace localhost with 127.0.0.1.

(The answer is based on answers of other people on this page.)

Alternatively, this solution works with both Apache2 version < 2.4 as well as >= 2.4. Make sure that the "version" module is enabled:

a2enmod version

And then use this code instead:

<IfVersion < 2.4>
    Allow from all
</IfVersion>
<IfVersion >= 2.4>
    Require all granted
</IfVersion>

Yes, if you redirect the output, it won't appear on the console. Use tee.

ls 2>&1 | tee /tmp/ls.txt

Here's something I found:

:pingtheserver
ping %input% | find "Reply" > nul
if not errorlevel 1 (
    echo server is online, up and running.
) else (
    echo host has been taken down wait 3 seconds to refresh
    ping 1.1.1.1 -n 1 -w 3000 >NUL
    goto :pingtheserver
) 

Note that ping 1.1.1.1 -n -w 1000 >NUL will wait 1 second but only works when connected to a network

In some cases, this error occurs when calling an async method without the await keyword, which can simply be solved by adding await before the method call. however, the answer might not be related to the mentioned question but it can help solving a similar error.

You could use the node STOMP client. This would let you integrate with a variety of message queues including:

• ActiveMQ
• RabbitMQ
• HornetQ

I haven't used this library before, so I can't vouch for its quality. But STOMP is a pretty simple protocol so I suspect you can hack it into submission if necessary.

Another option is to use beanstalkd with node. beanstalkd is a very fast "task queue" written in C that is very good if you don't need the feature flexibility of the brokers listed above.

Here is a simple solution. This is a late answer but may be simple one-

const data = {
  city: 'foo',
  year: 2020,
  person: {
    name: {
      firstName: 'john',
      lastName: 'doe'
    },
    age: 20,
    type: {
      a: 2,
      b: 3,
      c: {
        d: 4,
        e: 5
      }
    }
  },
}

function getKey(obj, res = [], parent = '') {
  const keys = Object.keys(obj);
  
  /** Loop throw the object keys and check if there is any object there */
  keys.forEach(key => {
    if (typeof obj[key] !== 'object') {
      // Generate the heirarchy
      parent ? res.push(`${parent}.${key}`) : res.push(key);
    } else {
      // If object found then recursively call the function with updpated parent
      let newParent = parent ? `${parent}.${key}` : key;
      getKey(obj[key], res, newParent);
    }
    
  });
}

const result = [];

getKey(data, result, '');

console.log(result);

.as-console-wrapper{min-height: 100%!important; top: 0}

There is more than one way to solve this problem.

I do not know the specifics but perhaps there is another way to trigger the PHP process. For instance if you need the code to run based on events in a SQL database you could setup a trigger to execute your script. This is really easy to do under PostgreSQL: http://www.postgresql.org/docs/current/static/external-pl.html .

Honestly I think your best bet is to create a Damon process using nohup. nohup allows the command to continue to execute even after the user has logged out:

nohup php myscript.php &

There is however a very serious problem. As you said PHP's memory manager is complete garbage, it was built with the assumption that a script is only executing for a few seconds and then exists. Your PHP script will start to use GIGABYTES of memory after only a few days. You MUST ALSO create a cron script that runs every 12 or maybe 24 hours that kills and re-spawns your php script like this:

killall -3 php
nohup php myscript.php &

But what if the script was in the middle of a job? Well kill -3 is an interrupt, its the same as doing a ctrl+c on the CLI. Your php script can catch this interrupt and exit gracefully using the PHP pcntl library: http://php.oregonstate.edu/manual/en/function.pcntl-signal.php

Here is an example:

function clean_up() {
  GLOBAL $lock;
  mysql_close();
  fclose($lock)
  exit();
}
pcntl_signal(SIGINT, 'clean_up');

The idea behind the $lock is that the PHP script can open a file with a fopen("file","w");. Only one process can have a write lock on a file, so using this you can make sure that only one copy of your PHP script is running.

Good Luck!

Why not store the function itself? myvar = mypackage.mymodule.myfunction is much cleaner.

UPDATE: Mongoose version (5.5.3)

remove() is deprecated and you can use deleteOne(), deleteMany(), or bulkWrite() instead.

As of "mongoose": ">=2.7.1" you can remove the document directly with the .remove() method rather than finding the document and then removing it which seems to me more efficient and easy to maintain.

See example:

Model.remove({ _id: req.body.id }, function(err) {
    if (!err) {
            message.type = 'notification!';
    }
    else {
            message.type = 'error';
    }
});

UPDATE:

As of mongoose 3.8.1, there are several methods that lets you remove directly a document, say:

• remove
• findByIdAndRemove
• findOneAndRemove

Refer to mongoose API docs for further information.

The following code works on both Linux and Windows, and not depending on external modules

import os
import subprocess
import platform
import re

def pid_alive(pid:int):
    """ Check For whether a pid is alive """


    system = platform.uname().system
    if re.search('Linux', system, re.IGNORECASE):
        try:
            os.kill(pid, 0)
        except OSError:
            return False
        else:
            return True
    elif re.search('Windows', system, re.IGNORECASE):
        out = subprocess.check_output(["tasklist","/fi",f"PID eq {pid}"]).strip()
        # b'INFO: No tasks are running which match the specified criteria.'

        if re.search(b'No tasks', out, re.IGNORECASE):
            return False
        else:
            return True
    else:
        raise RuntimeError(f"unsupported system={system}")

It can be easily enhanced in case you need

1. other platforms
2. other language

Line from above answer:

HtmlDocument doc = new HtmlDocument();

This doesn't work in VS 2015 C#. You cannot construct an HtmlDocument any more.

Another MS "feature" that makes things more difficult to use. Try HtmlAgilityPack.HtmlWeb and check out this link for some sample code.

pDialog = new ProgressDialog(this);

    // Set progressbar message
    pDialog.setMessage("Buffering...");
    pDialog.setIndeterminate(false);
    pDialog.setCancelable(false);
    // Show progressbar
    pDialog.show();

    try {
        // Start the MediaController
        MediaController mediacontroller = new MediaController(this);
        mediacontroller.setAnchorView(mVideoView);      

        Uri videoUri = Uri.parse(videoUrl);
        mVideoView.setMediaController(mediacontroller);
        mVideoView.setVideoURI(videoUri);

    } catch (Exception e) {

        e.printStackTrace();
    }

    mVideoView.requestFocus();
    mVideoView.setOnPreparedListener(new OnPreparedListener() {
        // Close the progress bar and play the video
        public void onPrepared(MediaPlayer mp) {
            pDialog.dismiss();
            mVideoView.start();
        }
    });
    mVideoView.setOnCompletionListener(new OnCompletionListener() {

        public void onCompletion(MediaPlayer mp) {
            if (pDialog.isShowing()) {
                pDialog.dismiss();
            }
            finish();               
        }
    });

You can use input text with "list" attribute, which refers to the datalist of values.

<input type="text" name="city" list="cityname">_x000D_
    <datalist id="cityname">_x000D_
      <option value="Boston">_x000D_
      <option value="Cambridge">_x000D_
    </datalist>

This creates a free text input field that also has a drop-down to select predefined choices. Attribution for example and more information: https://www.w3.org/wiki/HTML/Elements/datalist

This works and it is a lot easier to toggle that the methods above:

use inline: onended="if($(this).attr('data-loop')){ this.currentTime = 0; this.play(); }"

Turn the looping on by $(audio_element).attr('data-loop','1'); Turn the looping off by $(audio_element).removeAttr('data-loop');

An explicit default initialization can help:

struct foo {
    bool a {};
    bool b {};
    bool c {};
 } bar;

Behavior bool a {} is same as bool b = bool(); and return false.

We've faced this issue on Angular Cli 1.7.4 at times. Initially we've got

Cannot read property 'config' of null
TypeError: Cannot read property 'config' of null

And fixing this lead to the above issue.

We've removed package-lock.json

npm remove webpack

npm cache clean --force

You can also remove your node_modules folder. And then clean the cache. re-installed angular cli:

npm install @angular/[email protected]

And then you can do npm install again, just to make sure if everything is installed.

Then run

npm ls --depth 0

To make sure if all your node_modules are in sync with each other. If there are any dependency mismatching, this is the opportunity for us to figure out.

Finally run npm start/ng serve. it should fix everything.

This is out cheat code that we'll follow if we run into any issues with cli, before we dig deeper. 95% of times it fixes all the issues.

Hope that helps.

• UPDATE table_name SET Column1 = CONCAT('newtring', table_name.Column1) where 1
• UPDATE table_name SET Column1 = CONCAT('newtring', table_name.Column2) where 1
• UPDATE table_name SET Column1 = CONCAT('newtring', table_name.Column2, 'newtring2') where 1

We can concat same column or also other column of the table.

Throwing an exception is the best way of dealing with constructor failure. You should particularly avoid half-constructing an object and then relying on users of your class to detect construction failure by testing flag variables of some sort.

On a related point, the fact that you have several different exception types for dealing with mutex errors worries me slightly. Inheritance is a great tool, but it can be over-used. In this case I would probably prefer a single MutexError exception, possibly containing an informative error message.

It refers to lambda calculus, which is a formal system that just has lambda expressions, which represent a function that takes a function for its sole argument and returns a function. All functions in the lambda calculus are of that type, i.e., ? : ? ? ?.

Lisp used the lambda concept to name its anonymous function literals. This lambda represents a function that takes two arguments, x and y, and returns their product:

(lambda (x y) (* x y)) 

It can be applied in-line like this (evaluates to 50):

((lambda (x y) (* x y)) 5 10)

In our case it was the fact that the developer was running the application pool under his own account, and had reset his password but forgot to change it on the application pool. Duh...

I would do this the other way round.

In the OnLoad event for your Main form show the Logon form as a dialog. If the dialog result of that is OK then allow Main to continue loading, if the result is authentication failure then abort the load and show the message box.

EDIT Code sample(s)

private void MainForm_Load(object sender, EventArgs e)
{
    this.Hide();

    LogonForm logon = new LogonForm();

    if (logon.ShowDialog() != DialogResult.OK)
    {
        //Handle authentication failures as necessary, for example:
        Application.Exit();
    }
    else
    {
        this.Show();
    }
}

Another solution would be to show the LogonForm from the Main method in program.cs, something like this:

static void Main()
{
    Application.EnableVisualStyles();
    Application.SetCompatibleTextRenderingDefault(false);

    LogonForm logon = new LogonForm();

    Application.Run(logon);

    if (logon.LogonSuccessful)
    {
        Application.Run(new MainForm());
    }
}

In this example your LogonForm would have to expose out a LogonSuccessful bool property that is set to true when the user has entered valid credentials

Recently I had the same problem when using htmlTable() (‘htmlTable’ package) and I found a simpler solution: convert the data frame to a matrix with as.matrix():

htmlTable(as.matrix(df))

And be sure that the rownames are just indices. as.matrix() conservs the same columnames. That's it.

UPDATE

Following the comment of @DMR, I did't notice that htmlTable() has the parameter rnames = FALSE for cases like this. So a better answer would be:

htmlTable(df, rnames = FALSE)

If choosing between OAuth versions, go with OAuth 2.0.

OAuth bearer tokens should only be used with a secure transport.

OAuth bearer tokens are only as secure or insecure as the transport that encrypts the conversation. HTTPS takes care of protecting against replay attacks, so it isn't necessary for the bearer token to also guard against replay.

While it is true that if someone intercepts your bearer token they can impersonate you when calling the API, there are plenty of ways to mitigate that risk. If you give your tokens a long expiration period and expect your clients to store the tokens locally, you have a greater risk of tokens being intercepted and misused than if you give your tokens a short expiration, require clients to acquire new tokens for every session, and advise clients not to persist tokens.

If you need to secure payloads that pass through multiple participants, then you need something more than HTTPS/SSL, since HTTPS/SSL only encrypts one link of the graph. This is not a fault of OAuth.

Bearer tokens are easy to for clients to obtain, easy for clients to use for API calls and are widely used (with HTTPS) to secure public facing APIs from Google, Facebook, and many other services.

All these answers are partially wrong.

Microsoft has clarified that Community is for ANY USE as long as your revenue is under $1 Million US dollars. That is literally the only difference between Pro and Community. Corporate or free or not, irrelevant.

Even the lack of TFS support is not true. I can verify it is present and works perfectly.

EDIT: Here is an MSDN post regarding the $1M limit: MSDN (hint: it's in the VS 2017 license)

EDIT: Even over the revenue limit, open source is still free.

I know it's a late answer but I had the same problem and my solution was just adding implementation 'com.android.support:design:28.0.0 or any above support design libraries !!

Please check my answer here. Basically I just had to :

@Override
protected void onSaveInstanceState(Bundle outState) {
    //No call for super(). Bug on API Level > 11.
}

Don't make the call to super() on the saveInstanceState method. This was messing things up...

This is a known bug in the support package.

If you need to save the instance and add something to your outState Bundle you can use the following:

@Override
protected void onSaveInstanceState(Bundle outState) {
    outState.putString("WORKAROUND_FOR_BUG_19917_KEY", "WORKAROUND_FOR_BUG_19917_VALUE");
    super.onSaveInstanceState(outState);
}

In the end the proper solution was (as seen in the comments) to use :

transaction.commitAllowingStateLoss();

when adding or performing the FragmentTransaction that was causing the Exception.

you can also use just like this in newer version of sql,

select year('2001-02-16 20:38:40') as year,
month('2001-02-16 20:38:40') as month,
day('2001-02-16 20:38:40') as day,
hour('2001-02-16 20:38:40') as hour,
minute('2001-02-16 20:38:40') as minute

I updated my requirements.txt to have psycopg2==2.7.4 --no-binary=psycopg2 So that it build binaries on source

First use command

pip uninstall pyserial

Then run again

 pip install pyserial

The above commands will index it with system interpreter.

I think this is a bit of a dodge to your question, but why not fork them into processes? My understanding of networking (from the hazy days of yore, I don't really code networks at all) was that each incoming connection can be handled as a separate process, because then if someone does something nasty in your process, it doesn't nuke the entire program.

In case you want to do this on multiple lines that match a specific search:

• Up: :g/Your query/ normal ddp or :g/Your query/ m -1
• Down :g/Your query/ normal ddp or :g/Your query/ m +1

For Git GUI users it couldn't be much simpler. In Git GUI, choose the branch name from the drop down list in the "Rename Branch" dialog box created from the menu item Branch:Rename, type a New Name, and click "Rename". I have highlighted where to find the drop down list.

I agree with the other posts about leveraging elements of a preexisting/licensed codebase, performance, etc.

One thing I'd like to add is it's hard to pull nasty DRM tricks through a virtual machine.

Also I think there's a hubris component where project managers think they can make stable/reliable code with C++ with all the perks like having absolute control over their tools and resources, BUT without all the negatives that complicate and bog down their competition because "we're smarter than they are".

You need to add your ORACLE_HOME definition in your listener.ora file. Right now its not registered with any ORACLE_HOME.

Sample listener.ora

abc =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = abc.kma.com)(PORT = 1521))
    )
  )

SID_LIST_abc =
  (SID_LIST =
    (SID_DESC =
      (ORACLE_HOME= /abc/DbTier/11.2.0)
      (SID_NAME = abc)
    )
  )

This is probably a configuration error. If you insist on using PHP mail function, you will have to edit php.ini.

If you are looking for an easier and more versatile option (in my opinion), you should use PHPMailer.

Git checkout can actually pick out individual files from a revision. Just give it the commit hash and the file name. More detailed info here.

I guess the easiest way to fix this safely is to revert to the newest uncommited backup and then selectively pick out uncorrupted files from newer commits. Good luck!

Please refer to this for the example .The main point is to use the groupProperty() , and the related aggregate functions provided by the Projections class.

For example :

SELECT column_name, max(column_name) , min (column_name) , count(column_name)
FROM table_name
WHERE column_name > xxxxx
GROUP BY column_name

Its equivalent criteria object is :

List result = session.createCriteria(SomeTable.class)       
                    .add(Restrictions.ge("someColumn", xxxxx))      
                    .setProjection(Projections.projectionList()
                            .add(Projections.groupProperty("someColumn"))
                            .add(Projections.max("someColumn"))
                            .add(Projections.min("someColumn"))
                            .add(Projections.count("someColumn"))           
                    ).list();

If your target environment supports ES2015 (or you have a transpile step, eg with Babel), you can use the native Array.prototype.findIndex().

Given your example

const array = [ {id:1}, {id:2} ]
const desiredId = 2;
const index = array.findIndex(obj => obj.id === desiredId);

For Windows, you can check the official Intel MKL optimization for TensorFlow wheels that are compiled with AVX2. This solution speeds up my inference ~x3.

conda install tensorflow-mkl

var marker = new google.maps.Marker({
                position: new google.maps.LatLng(23.016427,72.571156),
                map: map,
                icon: 'images/map_marker_icon.png',
                title: 'Hi..!'
            });

apply local path on icon only

Try this, it has worked for me:

//input is the input element

input.focus(); //sets focus to element
var val = this.input.value; //store the value of the element
this.input.value = ''; //clear the value of the element
this.input.value = val; //set that value back.  

For the cursor to be move to the end, the input has to have focus first, then when the value is changed it will goto the end. If you set .value to the same, it won't change in chrome.

Ignore is exactly what the name implies.

It doesn't "throw away" something you don't need instead, it ignores the amount of characters you specify when you call it, up to the char you specify as a breakpoint.

It works with both input and output buffers.

Essentially, for std::cin statements you use ignore before you do a getline call, because when a user inputs something with std::cin, they hit enter and a '\n' char gets into the cin buffer. Then if you use getline, it gets the newline char instead of the string you want. So you do a std::cin.ignore(1000,'\n') and that should clear the buffer up to the string that you want. (The 1000 is put there to skip over a specific amount of chars before the specified break point, in this case, the \n newline character.)

If you are running the container as a service using docker swarm, you can do:

docker service update --env-add <you environment variable> <service_name>

Also remove using --env-rm

To make sure it's addedd as you wanted, just run: docker exec -it <container id> env

from random import random
my_list = range(10)
shuffled_list = sorted(my_list, key=lambda x: random())

This alternative may be useful for some applications where you want to swap the ordering function.

If you don't mind importing the sklearn library, I would recommend the method talked on this blog.

import pandas as pd
from sklearn import preprocessing

data = {'score': [234,24,14,27,-74,46,73,-18,59,160]}
cols = data.columns
df = pd.DataFrame(data)
df

min_max_scaler = preprocessing.MinMaxScaler()
np_scaled = min_max_scaler.fit_transform(df)
df_normalized = pd.DataFrame(np_scaled, columns = cols)
df_normalized

I also meet that problems,and just delete bottom code:

DELETE THESE LINES:
android {
    compileSdkVersion 22
    buildToolsVersion '22.0.1'
}

it worked?

Memcached will be faster if you are interested in performance, just even because Redis involves networking (TCP calls). Also internally Memcache is faster.

Redis has more features as it was mentioned by other answers.

tf.Print is now deprecated, here's how to use tf.print (lowercase p) instead.

While running a session is a good option, it is not always the way to go. For instance, you may want to print some tensor in a particular session.

The new print method returns a print operation which has no output tensors:

print_op = tf.print(tensor_to_print)

Since it has no outputs, you can't insert it in a graph the same way as you could with tf.Print. Instead, you can you can add it to control dependencies in your session in order to make it print.

sess = tf.compat.v1.Session()
with sess.as_default():
  tensor_to_print = tf.range(10)
  print_op = tf.print(tensor_to_print)
with tf.control_dependencies([print_op]):
  tripled_tensor = tensor_to_print * 3
sess.run(tripled_tensor)

Sometimes, in a larger graph, maybe created partly in subfunctions, it is cumbersome to propagate the print_op to the session call. Then, tf.tuple can be used to couple the print operation with another operation, which will then run with that operation whichever session executes the code. Here's how that is done:

print_op = tf.print(tensor_to_print)
some_tensor_list = tf.tuple([some_tensor], control_inputs=[print_op])
# Use some_tensor_list[0] instead of any_tensor below.

Common Table Expressions let you define what are essentially views that last only within the scope of your select, insert, update and delete statements. Depending on what you need to do they can be terribly useful.

\t in a string marks an escape sequence for a tab character. For a literal \, use \\.

Scaling an image with CSS is not quite possible, but a similar effect can be achieved in the following manner, though.

Use this markup:

<div id="background">
    <img src="img.jpg" class="stretch" alt="" />
</div>

with the following CSS:

#background {
    width: 100%; 
    height: 100%; 
    position: absolute; 
    left: 0px; 
    top: 0px; 
    z-index: 0;
}

.stretch {
    width:100%;
    height:100%;
}

and you should be done!

In order to scale the image to be "full bleed" and maintain the aspect ratio, you can do this instead:

.stretch { min-width:100%; min-height:100%; width:auto; height:auto; }

It works out quite nicely! If one dimension is cropped, however, it will be cropped on only one side of the image, rather than being evenly cropped on both sides (and centered). I've tested it in Firefox, Webkit, and Internet Explorer 8.

html {height: 101%;}

I use this cross browsers solution (note: I always use DOCTYPE declaration in 1st line, I don't know if it works in quirksmode, never tested it).

This will always show an ACTIVE vertical scroll bar in every page, vertical scrollbar will be scrollable only of few pixels.

When page contents is shorter than browser's visible area (view port) you will still see the vertical scrollbar active, and it will be scrollable only of few pixels.

In case you are obsessed with CSS validation (I'm obesessed only with HTML validation) by using this solution your CSS code would also validate for W3C because you are not using non standard CSS attributes like -moz-scrollbars-vertical

I am on Mac OS Sierra. I had to update /etc/paths and add /Users/my.username/.rbenv/shims to the top of the list.

The root cause for the question asked was the deployment/job/replicasets spec attribute strategy->type which defines what should happen when the pod will be destroyed (either implicitly or explicitly). In my case, it was Recreate.

As per @nomad's answer, deleting the deployment/job/replicasets is the simple fix to avoid experimenting with deadly combos before messing up the cluster as a novice user.

Try the following commands to understand the behind the scene actions before jumping into debugging :

kubectl get all -A -o name
kubectl get events -A | grep <pod-name>

You need to move the unique_ptr:

vec.push_back(std::move(ptr2x));

unique_ptr guarantees that a single unique_ptr container has ownership of the held pointer. This means that you can't make copies of a unique_ptr (because then two unique_ptrs would have ownership), so you can only move it.

Note, however, that your current use of unique_ptr is incorrect. You cannot use it to manage a pointer to a local variable. The lifetime of a local variable is managed automatically: local variables are destroyed when the block ends (e.g., when the function returns, in this case). You need to dynamically allocate the object:

std::unique_ptr<int> ptr(new int(1));

In C++14 we have an even better way to do so:

make_unique<int>(5);

You can use the ListAvailable option of Get-Module:

if (Get-Module -ListAvailable -Name SomeModule) {
    Write-Host "Module exists"
} 
else {
    Write-Host "Module does not exist"
}

1. Open config.default.php file under phpmyadmin/libraries/
2. Find $cfg['Servers'][$i]['host'] = 'localhost'; Change to $cfg['Servers'][$i]['host'] = '127.0.0.1';
3. refresh your phpmyadmin page, login

Only "pre" tag:

<pre>Name:      Waleed Hasees
Age:        33y
Address:    Palestine / Jein</pre>

You can apply any CSS class on this tag.

Be careful, the solution proposed with $a = array_combine($a, $a); will not work for numeric values.

I for example wanted to have a memory array(128,256,512,1024,2048,4096,8192,16384) to be the keys as well as the values however PHP manual states:

If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended.

So I solved it like this:

foreach($array as $key => $val) {
    $new_array[$val]=$val;
}

As stated on Installing MySQL-python on mac :

pip uninstall MySQL-python
brew install mysql
pip install MySQL-python

Then test it :

python -c "import MySQLdb"

"use strict";

Basically it enables the strict mode.

Strict Mode is a feature that allows you to place a program, or a function, in a "strict" operating context. In strict operating context, the method form binds this to the objects as before. The function form binds this to undefined, not the global set objects.

As per your comments you are telling some differences will be there. But it's your assumption. The Node.js code is nothing but your JavaScript code. All Node.js code are interpreted by the V8 JavaScript engine. The V8 JavaScript Engine is an open source JavaScript engine developed by Google for Chrome web browser.

So, there will be no major difference how "use strict"; is interpreted by the Chrome browser and Node.js.

Please read what is strict mode in JavaScript.

For more information:

1. Strict mode
2. ECMAScript 5 Strict mode support in browsers
3. Strict mode is coming to town
4. Compatibility table for strict mode
5. Stack Overflow questions: what does 'use strict' do in JavaScript & what is the reasoning behind it

ECMAScript 6 Code & strict mode. Following is brief from the specification:

10.2.1 Strict Mode Code

An ECMAScript Script syntactic unit may be processed using either unrestricted or strict mode syntax and semantics. Code is interpreted as strict mode code in the following situations:

• Global code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive (see 14.1.1).
• Module code is always strict mode code.
• All parts of a ClassDeclaration or a ClassExpression are strict mode code.
• Eval code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive or if the call to eval is a direct eval (see 12.3.4.1) that is contained in strict mode code.
• Function code is strict mode code if the associated FunctionDeclaration, FunctionExpression, GeneratorDeclaration, GeneratorExpression, MethodDefinition, or ArrowFunction is contained in strict mode code or if the code that produces the value of the function’s [[ECMAScriptCode]] internal slot begins with a Directive Prologue that contains a Use Strict Directive.
• Function code that is supplied as the arguments to the built-in Function and Generator constructors is strict mode code if the last argument is a String that when processed is a FunctionBody that begins with a Directive Prologue that contains a Use Strict Directive.

Additionally if you are lost on what features are supported by your current version of Node.js, this node.green can help you (leverages from the same data as kangax).

Edit / Update:

If you are using Typescript 3.7 or newer you can now also do:

    const data = change?.after?.data();

    if(!data) {
      console.error('No data here!');
       return null
    }

    const maxLen = 100;
    const msgLen = data.messages.length;
    const charLen = JSON.stringify(data).length;

    const batch = db.batch();

    if (charLen >= 10000 || msgLen >= maxLen) {

      // Always delete at least 1 message
      const deleteCount = msgLen - maxLen <= 0 ? 1 : msgLen - maxLen
      data.messages.splice(0, deleteCount);

      const ref = db.collection("chats").doc(change.after.id);

      batch.set(ref, data, { merge: true });

      return batch.commit();
    } else {
      return null;
    }

Original Response

Typescript is saying that change or data is possibly undefined (depending on what onUpdate returns).

So you should wrap it in a null/undefined check:

if(change && change.after && change.after.data){
    const data = change.after.data();

    const maxLen = 100;
    const msgLen = data.messages.length;
    const charLen = JSON.stringify(data).length;

    const batch = db.batch();

    if (charLen >= 10000 || msgLen >= maxLen) {

      // Always delete at least 1 message
      const deleteCount = msgLen - maxLen <= 0 ? 1 : msgLen - maxLen
      data.messages.splice(0, deleteCount);

      const ref = db.collection("chats").doc(change.after.id);

      batch.set(ref, data, { merge: true });

      return batch.commit();
    } else {
      return null;
    }
}

If you are 100% sure that your object is always defined then you can put this:

const data = change.after!.data();

I realize this is an old thread, but @alex 's answer needs to be marked as the correct answer

element.getBoundingClientRect() is an exact match to jQuery's $(element).offset()

And it's compatible with IE4+ ... https://developer.mozilla.org/en-US/docs/Web/API/Element.getBoundingClientRect

1) == evaluates reference equality in this case
2) im not too sure about the equals, but why not simply overriding the compare method and plant it inside MyClass?

Use bellow command from CLI interface

[root@localhost~]# mysqladmin variables -p<password> | grep datadir

just put

$a='Link1';
$b='Link2';

in your pass.php and you will get your answer and do a double quotation in your link.php:

echo '<a href="pass.php?link=' . $a . '">Link 1</a>';

if use Inline CSS you use

<img src="http://img705.imageshack.us/img705/119/original120x75.png" style="height:100px;width:100px;" alt="705"/>

Otherwise you can use class properties which related with a separate css file (styling your website) as like In CSS File

.imgSize {height:100px;width:100px;}

In HTML File

<img src="http://img705.imageshack.us/img705/119/original120x75.png" style="height:100px;width:100px;" alt="705"/>

1. Open web.config in the directory where the old pages reside

2. Then add code for the old location path and new destination as follows:

   <configuration>
     <location path="services.htm">
       <system.webServer>
         <httpRedirect enabled="true" destination="http://domain.com/services" httpResponseStatus="Permanent" />
       </system.webServer>
     </location>
     <location path="products.htm">
       <system.webServer>
         <httpRedirect enabled="true" destination="http://domain.com/products" httpResponseStatus="Permanent" />
       </system.webServer>
     </location>
   </configuration>
   

You may add as many location paths as necessary.

If you use the library sugar.js, you can write arr.min() and arr.max() as you suggest. You can also get min and max values from non-numeric arrays.

min( map , all = false ) Returns the element in the array with the lowest value. map may be a function mapping the value to be checked or a string acting as a shortcut. If all is true, will return all min values in an array.

max( map , all = false ) Returns the element in the array with the greatest value. map may be a function mapping the value to be checked or a string acting as a shortcut. If all is true, will return all max values in an array.

Examples:

[1,2,3].min() == 1
['fee','fo','fum'].min('length') == "fo"
['fee','fo','fum'].min('length', true) == ["fo"]
['fee','fo','fum'].min(function(n) { return n.length; }); == "fo"
[{a:3,a:2}].min(function(n) { return n['a']; }) == {"a":2}
['fee','fo','fum'].max('length', true) == ["fee","fum"]

Libraries like Lo-Dash and underscore.js also provide similar powerful min and max functions:

Example from Lo-Dash:

_.max([4, 2, 8, 6]) == 8
var characters = [
  { 'name': 'barney', 'age': 36 },
  { 'name': 'fred',   'age': 40 }
];
_.max(characters, function(chr) { return chr.age; }) == { 'name': 'fred', 'age': 40 }

This is no longer up-to-date!

Push.default is unset; its implicit value has changed in
Git 2.0 from 'matching' to 'simple'. To squelch this message
and maintain the traditional behavior, use:

  git config --global push.default matching

To squelch this message and adopt the new behavior now, use:

  git config --global push.default simple

When push.default is set to 'matching', git will push local branches
to the remote branches that already exist with the same name.

Since Git 2.0, Git defaults to the more conservative 'simple'
behavior, which only pushes the current branch to the corresponding
remote branch that 'git pull' uses to update the current branch.

Redirection of program output is performed by the shell.

grep ... > output.txt

grep has no mechanism for adding blank lines between each match, but does provide options such as context around the matched line and colorization of the match itself. See the grep(1) man page for details, specifically the -C and --color options.

In case you need the [] syntax, useful for "edit forms" when you need to pass parameters like id with the route, you would do something like:

[routerLink]="['edit', business._id]"

As for an "about page" with no parameters like yours,

[routerLink]="/about"

or

[routerLink]=['about']

will do the trick.

Stumbled upon this question when was looking for fast, modern, platform independent and elegant solution. Didnt like any of above, cpp-netlib would be the winner but it has horrific memory vulnerability in "decoded" function. So I came up with boost's spirit qi/karma solution.

namespace bsq = boost::spirit::qi;
namespace bk = boost::spirit::karma;
bsq::int_parser<unsigned char, 16, 2, 2> hex_byte;
template <typename InputIterator>
struct unescaped_string
    : bsq::grammar<InputIterator, std::string(char const *)> {
  unescaped_string() : unescaped_string::base_type(unesc_str) {
    unesc_char.add("+", ' ');

    unesc_str = *(unesc_char | "%" >> hex_byte | bsq::char_);
  }

  bsq::rule<InputIterator, std::string(char const *)> unesc_str;
  bsq::symbols<char const, char const> unesc_char;
};

template <typename OutputIterator>
struct escaped_string : bk::grammar<OutputIterator, std::string(char const *)> {
  escaped_string() : escaped_string::base_type(esc_str) {

    esc_str = *(bk::char_("a-zA-Z0-9_.~-") | "%" << bk::right_align(2,0)[bk::hex]);
  }
  bk::rule<OutputIterator, std::string(char const *)> esc_str;
};

The usage of above as following:

std::string unescape(const std::string &input) {
  std::string retVal;
  retVal.reserve(input.size());
  typedef std::string::const_iterator iterator_type;

  char const *start = "";
  iterator_type beg = input.begin();
  iterator_type end = input.end();
  unescaped_string<iterator_type> p;

  if (!bsq::parse(beg, end, p(start), retVal))
    retVal = input;
  return retVal;
}

std::string escape(const std::string &input) {
  typedef std::back_insert_iterator<std::string> sink_type;
  std::string retVal;
  retVal.reserve(input.size() * 3);
  sink_type sink(retVal);
  char const *start = "";

  escaped_string<sink_type> g;
  if (!bk::generate(sink, g(start), input))
    retVal = input;
  return retVal;
}

You can use Decode as well:

SELECT DISTINCT a.item, decode(b.salesman,'VIKKIE','ICKY',Else),NVL(a.manufacturer,'Not Set')Manufacturer
FROM inv_items a, arv_sales b
WHERE a.co = b.co
      AND A.ITEM_KEY = b.item_key
      AND a.co = '100'
AND a.item LIKE 'BX%'
AND b.salesman in ('01','15')
AND trans_date BETWEEN to_date('010113','mmddrr')
                         and to_date('011713','mmddrr')
GROUP BY a.item, b.salesman, a.manufacturer
ORDER BY a.item

These three commands have entirely different purposes. They are not even remotely similar.

git revert

This command creates a new commit that undoes the changes from a previous commit. This command adds new history to the project (it doesn't modify existing history).

git checkout

This command checks-out content from the repository and puts it in your work tree. It can also have other effects, depending on how the command was invoked. For instance, it can also change which branch you are currently working on. This command doesn't make any changes to the history.

git reset

This command is a little more complicated. It actually does a couple of different things depending on how it is invoked. It modifies the index (the so-called "staging area"). Or it changes which commit a branch head is currently pointing at. This command may alter existing history (by changing the commit that a branch references).

Using these commands

If a commit has been made somewhere in the project's history, and you later decide that the commit is wrong and should not have been done, then git revert is the tool for the job. It will undo the changes introduced by the bad commit, recording the "undo" in the history.

If you have modified a file in your working tree, but haven't committed the change, then you can use git checkout to checkout a fresh-from-repository copy of the file.

If you have made a commit, but haven't shared it with anyone else and you decide you don't want it, then you can use git reset to rewrite the history so that it looks as though you never made that commit.

These are just some of the possible usage scenarios. There are other commands that can be useful in some situations, and the above three commands have other uses as well.

There is a trick, Arithmetic exceptions only happen when you are playing around with integers and only during / or % operation.

If there is any floating point number in an arithmetic operation, internally all integers will get converted into floating point. This may help you to remember things easily.

Try using an Object, not an Array:

var test = new Object(); test[2300] = 'Some string';

This is because PHP uses the period character . for string concatenation, not the plus character +. Therefore to append to a string you want to use the .= operator:

for ($i=1;$i<=100;$i++)
{
    $selectBox .= '<option value="' . $i . '">' . $i . '</option>';
}
$selectBox .= '</select>';

Class Meta is the place in your code logic where your model.fields MEET With your form.widgets. So under Class Meta() you create the link between your model' fields and the different widgets you want to have in your form.

With C# 6.0, this is now a non-issue as you can do:

nameof(SomeProperty)

This expression is resolved at compile-time to "SomeProperty".

MSDN documentation of nameof.

First, three useful things about const (other than the scope improvements it shares with let):

• It documents for people reading the code later that the value must not change.
• It prevents you (or anyone coming after you) from changing the value unless they go back and change the declaration intentionally.
• It might save the JavaScript engine some analysis in terms of optimization. E.g., you've declared that the value cannot change, so the engine doesn't have to do work to figure out whether the value changes so it can decide whether to optimize based on the value not changing.

Your questions:

When is it appropriate to use const in place of var?

You can do it any time you're declaring a variable whose value never changes. Whether you consider that appropriate is entirely down to your preference / your team's preference.

Should it be used every time a variable which is not going to be re-assigned is declared?

That's up to you / your team.

Does it actually make any difference if var is used in place ofconst` or vice-versa?

Yes:

• var and const have different scope rules. (You might have wanted to compare with let rather than var.) Specifically: const and let are block-scoped and, when used at global scope, don't create properties on the global object (even though they do create globals). var has either global scope (when used at global scope) or function scope (even if used in a block), and when used at global scope, creates a property on the global object.
• See my "three useful things" above, they all apply to this question.

Starting with go 1.8 (Q2 2017), GOPATH will be set for you by default to $HOME/go

See issue 17262 and Rob Pike's comment:

$HOME/go it will be.
There is no single best answer but this is short and sweet, and it can only be a problem to choose that name if $HOME/go already exists, which will only happy for experts who already have go installed and will understand GOPATH.

Use the date function:

select date(timestamp_field) from table

From a character field representation to a date you can use:

select date(substring('2011/05/26 09:00:00' from 1 for 10));

Test code:

create table test_table (timestamp_field timestamp);
insert into test_table (timestamp_field) values(current_timestamp);
select timestamp_field, date(timestamp_field) from test_table;

Test result:

add cv2.waitKey(0) in the end.

Try:

s = filter(str.isalnum, s)

in Python3:

s = ''.join(filter(str.isalnum, s))

Edit: realized that the OP wants to replace non-chars with '*'. My answer does not fit

This will work:

The problem may happen when you're trying to read a list with a single element as a JsonArray rather than a JsonNode or vice versa.

Since you can't know for sure if the returned list contains a single element (so the json looks like this {...}) or multiple elements (and the json looks like this [{...},{...}]) - you'll have to check in runtime the type of the element.

It should look like this:

(Note: in this code sample I'm using com.fasterxml.jackson)

String jsonStr = response.readEntity(String.class);
ObjectMapper mapper = new ObjectMapper();
JsonNode rootNode = mapper.readTree(jsonStr);

// Start by checking if this is a list -> the order is important here:                      
if (rootNode instanceof ArrayNode) {
    // Read the json as a list:
    myObjClass[] objects = mapper.readValue(rootNode.toString(), myObjClass[].class);
    ...
} else if (rootNode instanceof JsonNode) {
    // Read the json as a single object:
    myObjClass object = mapper.readValue(rootNode.toString(), myObjClass.class);
    ...
} else {
    ...
}

I stole this convienent class from somewhere here at StackOverflow to convert anything streamable to a string:

// make_string
class make_string {
public:
  template <typename T>
  make_string& operator<<( T const & val ) {
    buffer_ << val;
    return *this;
  }
  operator std::string() const {
    return buffer_.str();
  }
private:
  std::ostringstream buffer_;
};

And then you use it as;

string str = make_string() << 6 << 8 << "hello";

Quite nifty!

Also I use this function to convert strings to anything streamable, althrough its not very safe if you try to parse a string not containing a number; (and its not as clever as the last one either)

// parse_string
template <typename RETURN_TYPE, typename STRING_TYPE>
RETURN_TYPE parse_string(const STRING_TYPE& str) {
  std::stringstream buf;
  buf << str;
  RETURN_TYPE val;
  buf >> val;
  return val;
}

Use as:

int x = parse_string<int>("78");

You might also want versions for wstrings.

This is what do you want? DEMO. Try to shrink the browser's window and you'll see that the elements will be ordered.

What I used? Flexible Box Model or Flexbox.

Just add the follow CSS classes to your container element (in this case div#container):

flex-init-setup and flex-ppal-setup.

Where:

1. flex-init-setup means flexbox init setup; and
2. flex-ppal-setup means flexbox principal setup

Here are the CSS rules:

 .flex-init-setup {
     display: -webkit-box;
     display: -moz-box;
     display: -webkit-flex;
     display: -ms-flexbox;
     display: flex;
 }
 .flex-ppal-setup {
     -webkit-flex-flow: column wrap;
     -moz-flex-flow: column wrap;
     flex-flow: column wrap;
     -webkit-justify-content: center;
     -moz-justify-content: center;
     justify-content: center;
 }

function getScreenWidth()
{
   var de = document.body.parentNode;
   var db = document.body;
   if(window.opera)return db.clientWidth;
   if (document.compatMode=='CSS1Compat') return de.clientWidth;
   else return db.clientWidth;
}

You can do this:

app-routing-modules.ts:

import { NgModule                  }    from '@angular/core';
import { RouterModule, Routes      }    from '@angular/router';
import { PowerBoosterComponent     }    from './component/power-booster.component';


export const routes: Routes = [
  { path:  'pipeexamples',component: PowerBoosterComponent, 
data:{  name:'shubham' } },
    ];
    @NgModule({
      imports: [ RouterModule.forRoot(routes) ],
      exports: [ RouterModule ]
    })
    export class AppRoutingModule {}

In this above route, I want to send data via a pipeexamples path to PowerBoosterComponent.So now I can receive this data in PowerBoosterComponent like this:

power-booster-component.ts

import { Component, OnInit } from '@angular/core';
import { Router, ActivatedRoute, Params, Data } from '@angular/router';

@Component({
  selector: 'power-booster',
  template: `
    <h2>Power Booster</h2>`
})

export class PowerBoosterComponent implements OnInit {
  constructor(
    private route: ActivatedRoute,
    private router: Router

  ) { }
  ngOnInit() {
    //this.route.snapshot.data['name']
    console.log("Data via params: ",this.route.snapshot.data['name']);
  }
}

So you can get the data by this.route.snapshot.data['name'].

                try (FileInputStream inputStream = new FileInputStream(file)) {
                    IOUtils.copy(inputStream, zipOutputStream);
                }
                zipOutputStream.closeEntry();
            } else if (file.isDirectory()) {
                processFolder(file, zipOutputStream, prefixLength);
            }
        }
    }
}

In Python 3, urllib2 was replaced by two in-built modules named urllib.request and urllib.error

Adapted from source

So replace this:

import urllib2

With this:

import urllib.request as urllib2

You can also put the item with the default value selected out of the ng-repeat like follow :

<div ng-app="app" ng-controller="myCtrl">
    <select class="form-control" ng-change="unitChanged()" ng-model="data.unit">
        <option value="yourDefaultValue">Default one</option>
        <option ng-selected="data.unit == item.id" ng-repeat="item in units" ng-value="item.id">{{item.label}}</option>
    </select>
</div>

and don't forget the value atribute if you leave it blank you will have the same issue.

First add the new files:

svn add fileName

Then commit all new and modified files

svn ci <files_separated_by_space> -m "Commit message|ReviewID:XXXX"

If non source files are to be committed then

svn ci <files> -m "Commit msg|ReviewID:NON-SOURCE"

Try this: Goto project property -> C/C++ -> Code generation -> Runtime Library Select from combobox value : Multi-threaded DLL (/MD) It work for me :)

you can join both tables even on UPDATE statements,

UPDATE  a
SET     a.marks = b.marks
FROM    tempDataView a
        INNER JOIN tempData b
            ON a.Name = b.Name

• SQLFiddle Demo

for faster performance, define an INDEX on column marks on both tables.

using SUBQUERY

UPDATE  tempDataView 
SET     marks = 
        (
          SELECT marks 
          FROM tempData b 
          WHERE tempDataView.Name = b.Name
        )

• SQLFiddle Demo

It is important to highlight that the Property (MaximumErrorCount) that needs to be changed must be set as more than 0 (which is the default) in the Package level and not in the specific control that is showing the error (I tried this and it does not work!)

Be sure that in the Properties Window, the Pull down menu is set to "Package", then look for the property MaximumErrorCount to change it.

here's what I did to alert user in case their network went down or upon page update failure:

1. I have a div-tag on the page where I put current time and update this tag every 10 seconds. It looks something like this: <div id="reloadthis">22:09:10</div>

2. At the end of the javascript function that updates the time in the div-tag, I put this (after time is updated with AJAX):

   var new_value = document.getElementById('reloadthis').innerHTML;
   var new_length = new_value.length;
   if(new_length<1){
       alert("NETWORK ERROR!");
   }
   

That's it! You can replace the alert-part with anything you want, of course. Hope this helps.

Had a similar issue while installing "Lua" in OS X using homebrew. I guess it could be useful for other users facing similar issue in homebrew.

On running the command:

$ brew install lua

The command returned an error:

Error: /usr/local/opt/lua is not a valid keg
(in general the error can be of /usr/local/opt/ is not a valid keg

FIXED it by deleting the file/directory it is referring to, i.e., deleting the "/usr/local/opt/lua" file.

root-user # rm -rf /usr/local/opt/lua

And then running the brew install command returned success.

If you want to concatenate the input, then replace printf("%s\n", buffer); with strcat(big_buffer, buffer);. Also create and initialize the big buffer at the beginning: char *big_buffer = new char[BIG_BUFFERSIZE]; big_buffer[0] = '\0';. You should also prevent a buffer overrun by verifying the current buffer length plus the new buffer length does not exceed the limit: if ((strlen(big_buffer) + strlen(buffer)) < BIG_BUFFERSIZE). The modified program would look like this:

#include <stdio.h>
#include <string.h>

#define BUFFERSIZE 10
#define BIG_BUFFERSIZE 1024

int main (int argc, char *argv[])
{
    char buffer[BUFFERSIZE];
    char *big_buffer = new char[BIG_BUFFERSIZE];
    big_buffer[0] = '\0';
    printf("Enter a message: \n");
    while(fgets(buffer, BUFFERSIZE , stdin) != NULL)
    {
        if ((strlen(big_buffer) + strlen(buffer)) < BIG_BUFFERSIZE)
        {
            strcat(big_buffer, buffer);
        }
    }
    return 0;
}

Recursively add subfolders,

for i in `find . -name "*.java" -type f`; do
    echo "$i"
done

Read line by line, not the whole file:

for line in open(file_name, 'rb'):
    # process line here

Even better use with for automatically closing the file:

with open(file_name, 'rb') as f:
    for line in f:
        # process line here

The above will read the file object using an iterator, one line at a time.

Although this is a old post, I have spent 3 hours to fix my issue and I think this might help someone in future.

Here is my jquery-dialog hack to show html content inside an <iframe> :

let modalProperties = {autoOpen: true, width: 900, height: 600, modal: true, title: 'Modal Title'};
let modalHtmlContent = '<div>My Content First div</div><div>My Content Second div</div>';

// create wrapper iframe
let wrapperIframe = $('<iframe src="" frameborder="0" style="width:100%; height:100%;"></iframe>');

// create jquery dialog by a 'div' with 'iframe' appended
$("<div></div>").append(wrapperIframe).dialog(modalProperties);

// insert html content to iframe 'body'
let wrapperIframeDocument = wrapperIframe[0].contentDocument;
let wrapperIframeBody = $('body', wrapperIframeDocument);
wrapperIframeBody.html(modalHtmlContent);

For running c++ files run below command, Assuming file name is "main.cpp"

1.Compile to make object file from c++ file.

g++ -c main.cpp -o main.o

2.Since #include <conio.h> does not support in MacOS so we should use its alternative which supports in Mac that is #include <curses.h>. Now object file needs to be converted to executable file. To use curses.h we have to use library -lcurses.

g++ -o main main.o -lcurses

3.Now run the executable.

./main

The best way to do this would be to use the promise returning function as it is, like this

lookupValue(file).then(function(res) {
    // Write the code which depends on the `res.val`, here
});

The function which invokes an asynchronous function cannot wait till the async function returns a value. Because, it just invokes the async function and executes the rest of the code in it. So, when an async function returns a value, it will not be received by the same function which invoked it.

So, the general idea is to write the code which depends on the return value of an async function, in the async function itself.

# install pythonp
python -m pip install pythonp

pythonp "5*5"

pythonp "1 / (1+math.exp(0.5))"
0.3775406687981454

# define a custom function and pass it to another higher-order function
pythonp "n=10;functools.reduce(lambda x,y:x*y, range(1,n+1))"

Use Visual Studio Setup project. Setup project can automatically include .NET framework setup in your installation package:

Here is my step-by-step for windows forms application:

1. Create setup project. You can use Setup Wizard.

   

2. Select project type.

   

3. Select output.

   

4. Hit Finish.

5. Open setup project properties.

   

6. Chose to include .NET framework.

   

7. Build setup project

8. Check output

   

Note: The Visual Studio Installer projects are no longer pre-packed with Visual Studio. However, in Visual Studio 2013 you can download them by using:

Tools > Extensions and Updates > Online (search) > Visual Studio Installer Projects

If you've got a Mac the easiest way to split those would be to use DfontSplitter, available at https://peter.upfold.org.uk/projects/dfontsplitter

The Windows version they provide doesn't work with ttc files.

use array_keys() to get an array of all the unique keys.

Note that an array with named keys like your $arr can also be accessed with numeric indexes, like $arr[0].

http://php.net/manual/en/function.array-keys.php

Also you can bind to the public static members of the enum directly by using reflection:

typeof(Suit).GetMembers(BindingFlags.Public | BindingFlags.Static)
    .ToList().ForEach(x => DoSomething(x.Name));

The error message seems self-explanatory. You can't instantiate an instance of an interface, and you've declared IUser as an interface. (The same rule applies to abstract classes.) The whole point of an interface is that it doesn't do anything—there is no implementation provided for its methods.

However, you can instantiate an instance of a class that implements that interface (provides an implementation for its methods), which in your case is the User class.

Thus, your code needs to look like this:

IUser user = new User();

This instantiates an instance of the User class (which provides the implementation), and assigns it to an object variable for the interface type (IUser, which provides the interface, the way in which you as the programmer can interact with the object).

Of course, you could also write:

User user = new User();

which creates an instance of the User class and assigns it to an object variable of the same type, but that sort of defeats the purpose of a defining a separate interface in the first place.

Looks like moment.js is the most popular and with active development:

moment("2010-01-01T05:06:07", moment.ISO_8601);

Like you I also faced many problems implementing OCR in Android, but after much Googling I found the solution, and it surely is the best example of OCR.

Let me explain using step-by-step guidance.

First, download the source code from https://github.com/rmtheis/tess-two.

Import all three projects. After importing you will get an error. To solve the error you have to create a res folder in the tess-two project

First, just create res folder in tess-two by tess-two->RightClick->new Folder->Name it "res"

After doing this in all three project the error should be gone.

Now download the source code from https://github.com/rmtheis/android-ocr, here you will get best example.

Now you just need to import it into your workspace, but first you have to download android-ndk from this site:

http://developer.android.com/tools/sdk/ndk/index.html i have windows 7 - 32 bit PC so I have download http://dl.google.com/android/ndk/android-ndk-r9-windows-x86.zip this file

Now extract it suppose I have extract it into E:\Software\android-ndk-r9 so I will set this path on Environment Variable

Right Click on MyComputer->Property->Advance-System-Settings->Advance->Environment Variable-> find PATH on second below Box and set like path like below picture

done it

Now open cmd and go to on D:\Android Workspace\tess-two like below

If you have successfully set up environment variable of NDK then just type ndk-build just like above picture than enter you will not get any kind of error and all file will be compiled successfully:

Now download other source code also from https://github.com/rmtheis/tess-two , and extract and import it and give it name OCRTest, like in my PC which is in D:\Android Workspace\OCRTest

Import test-two in this and run OCRTest and run it; you will get the best example of OCR.

Geckofx and Webkit.net were both promising at first, but they didn't keep up to date with Firefox and Chrome respectively while as Internet Explorer improved, so did the Webbrowser control, though it behaves like IE7 by default regardless of what IE version you have but that can be fixed by going into the registry and change it to IE9 allowing HTML5.

I like to do this witch i think is cleaner :

1 - Add the model to namespace:

use App\Employee;

2 - then you can do :

$employees = Employee::get();

or maybe somthing like this:

$employee = Employee::where('name', 'John')->first();

DroidParts has ImageFetcher that requires zero configuration to get started.

• Uses a disk & in-memory Least Recently Used (LRU) cache.
• Efficiently decodes images.
• Supports modifying bitmaps in background thread.
• Has simple cross-fade.
• Has image loading progress callback.

Clone DroidPartsGram for an example:

am startservice <INTENT>   

or actually from the OS shell

adb shell am startservice <INTENT>

No, no, NO!

In single threated tasks you don't need to use Iterator, moreover, CopyOnWriteArrayList (due to performance hit).

Solution is much simpler: try to use canonical for loop instead of for-each loop.

According to Java copyright owners (some years ago Sun, now Oracle) for-each loop guide, it uses iterator to walk through collection and just hides it to make code looks better. But, unfortunately as we can see, it produced more problems than profits, otherwise this topic would not arise.

For example, this code will lead to java.util.ConcurrentModificationException when entering next iteration on modified ArrayList:

        // process collection
        for (SomeClass currElement: testList) {

            SomeClass founDuplicate = findDuplicates(currElement);
            if (founDuplicate != null) {
                uniqueTestList.add(founDuplicate);
                testList.remove(testList.indexOf(currElement));
            }
        }

But following code works just fine:

    // process collection
    for (int i = 0; i < testList.size(); i++) {
        SomeClass currElement = testList.get(i);

        SomeClass founDuplicate = findDuplicates(currElement);
        if (founDuplicate != null) {
            uniqueTestList.add(founDuplicate);
            testList.remove(testList.indexOf(currElement));
            i--; //to avoid skipping of shifted element
        }
    }

So, try to use indexing approach for iterating over collections and avoid for-each loop, as they are not equivalent! For-each loop uses some internal iterators, which check collection modification and throw ConcurrentModificationException exception. To confirm this, take a closer look at the printed stack trace when using first example that I've posted:

Exception in thread "main" java.util.ConcurrentModificationException
    at java.util.AbstractList$Itr.checkForComodification(AbstractList.java:372)
    at java.util.AbstractList$Itr.next(AbstractList.java:343)
    at TestFail.main(TestFail.java:43)

For multithreading use corresponding multitask approaches (like synchronized keyword).

I have done it this way. so that i get an object to access to separate the values.With this u can pass the cookie to the parent and then you can access your values by the keys like

var cookies=getCookieVal(mycookie);
alert(cookies.mykey);
function getCookieVal(parent) {
            var cookievalue = $.cookie(parent).split('&');
            var obj = {};
            $.each(cookievalue, function (i, v) {
                var key = v.substr(0, v.indexOf("="));
                var val = v.substr(v.indexOf("=") + 1, v.length);

                obj[key] = val;

            });
            return obj;
        }

                thread.interrupt();

                // go over every thread running and stop every one of them
                listThread.stream().forEach(tread -> tread.interrupt());

                // relaunch all the Thread via the main function
                getStockHistory();
            }
        };

        t1.start();
        t1.setUncaughtExceptionHandler(h);

        listThread.add(t1);

    }

}

To sum up :

You have a main function that create multiple thread, each of them has UncaughtExceptionHandler which is trigger by any Exception inside of a thread. You add every Thread to a List. If a UncaughtExceptionHandler is trigger it will loop through the List, stop every Thread and relaunch the main function recreation all the Thread.

May be it's too late to answer, but i found a very simple way to do this(without a hack).

1. Put your dll in GAC (for 3.5 Drag Drop inside "C:\Windows\assembly\")
2. GoTo Projects --> Properties
3. Click Reference Path (for 3.5 it's "C:\Windows\assembly\")
4. and Build

Hope it helps

My synopsis of rfc2397 is:

Once you've got your base64 encoded image data put it inside the <Image></Image> tags prefixed with "data:{mimetype};base64," this is similar to the prefixing done in the parenthesis of url() definition in CSS or in the quoted value of the src attribute of the img tag in [X]HTML. You can test the data url in firefox by putting the data:image/... line into the URL field and pressing enter, it should show your image.

For actually encoding I think we need to go over all your options, not just PHP, because there's so many ways to base64 encode something.

1. Use the base64 command line tool. It's part of the GNU coreutils (v6+) and pretty much default in any Cygwin, Linux, GnuWin32 install, but not the BSDs I tried. Issue: $ base64 imagefile.ico > imagefile.base64.txt
2. Use a tool that features the option to convert to base64, like Notepad++ which has the feature under plugins->MIME tools->base64 Encode
3. Email yourself the file and view the raw email contents, copy and paste.
4. Use a web form.

A note on mime-types: I would prefer you use one of image/png image/jpeg or image/gif as I can't find the popular image/x-icon. Should that be image/vnd.microsoft.icon? Also the other formats are much shorter.

The SQL command is:

ALTER TABLE <tablename> ADD CONSTRAINT
            <constraintname> UNIQUE NONCLUSTERED
    (
                <columnname>
    )

See the full syntax here.

If you want to do it from a Database Diagram:

• right-click on the table and select 'Indexes/Keys'
• click the Add button to add a new index
• enter the necessary info in the Properties on the right hand side:
  • the columns you want (click the ellipsis button to select)
  • set Is Unique to Yes
  • give it an appropriate name

As has been discussed elsewhere, the .length property reference is failing because theHref is undefined. However, be aware of any solution which involves comparing theHref to undefined, which is not a keyword in JavaScript and can be redefined.

For a full discussion of checking for undefined variables, see Detecting an undefined object property and the first answer in particular.
