What finally worked for me (Grails now works smoothly) is doing almost like Steve B. has pointed out:

JAVA_HOME=/usr/lib/jvm/default-java

This way if the user changes the default JDK for the system, JAVA_HOME still works.

default-java is a symlink to the current JVM.

You can also declare 'x' with the keyword var:

var x = new
{
  driver = new
  {
    firstName = "john",
    lastName = "walter"
  },
  car = new
  {
    brand = "BMW"
  }
};

This will allow you to declare your x object inline, but you will have to name your 2 anonymous objects, in order to access them. You can have an array of "x" :

x.driver.firstName // "john"
x.car.brand // "BMW"

var y = new[] { x, x, x, x };
y[1].car.brand; // "BMW"

As hktang above indicates:

one Click opens the file in preview mode (header text in italics)

Double click the same file, it goes out of preview-mode (header text changes from italic to normal font)

I think this is a "comprimise" feature allowing users, to "navigate" both worlds; preview and none-preview.

• All you do is click the file to open it in the right panel.
• Then immediately double click it to keep it there.
• Or - just treble click. File opens in none preview mode.

For others, if clearfix does not solve this for you, add margins to the non-floated sibling that is/are the same as the width(s) of the floated sibling(s).

You can also get this information from the command line using the xcodebuild command with the -showBuildSettings switch:

$ xcodebuild -project myProj.xcodeproj -target "myTarg" -showBuildSettings

This will dump a list like the one shown above to the standard output.

smalldatetime has range up to June 6, 2079 so you can use

ORDER BY ISNULL(Next_Contact_Date, '2079-06-05T23:59:00')

If no legitimate records will have that date.

If this is not an assumption you fancy relying on a more robust option is sorting on two columns.

ORDER BY CASE WHEN Next_Contact_Date IS NULL THEN 1 ELSE 0 END, Next_Contact_Date

Both of the above suggestions are not able to use an index to avoid a sort however and give similar looking plans.

One other possibility if such an index exists is

SELECT 1 AS Grp, Next_Contact_Date 
FROM T 
WHERE Next_Contact_Date IS NOT NULL
UNION ALL
SELECT 2 AS Grp, Next_Contact_Date 
FROM T 
WHERE Next_Contact_Date IS NULL
ORDER BY Grp, Next_Contact_Date

Here is solution for dynamic queries.

For example if you have more tables with different suffix:

dbo.SOMETHINGTABLE_ONE, dbo.SOMETHINGTABLE_TWO

Code:

DECLARE @INDEX AS NVARCHAR(20)
DECLARE @CheckVALUE AS NVARCHAR(max) = 'SELECT COUNT(SOMETHING) FROM 
dbo.SOMETHINGTABLE_'+@INDEX+''
DECLARE @tempTable Table (TempVALUE int)
DECLARE @RESULTVAL INT

INSERT INTO @tempTable
    EXEC sp_executesql @CheckVALUE

SET @RESULTVAL = (SELECT * FROM @tempTable)

DELETE @tempTable

SELECT @RESULTVAL 

Encryption and hash algorithms work in similar ways. In each case, there is a need to create confusion and diffusion amongst the bits. Boiled down, confusion is creating a complex relationship between the key and the ciphertext, and diffusion is spreading the information of each bit around.

Many hash functions actually use encryption algorithms (or primitives of encryption algorithms. For example, the SHA-3 candidate Skein uses Threefish as the underlying method to process each block. The difference is that instead of keeping each block of ciphertext, they are destructively, deterministically merged together to a fixed length

Like it's written up there, you forget to type #include <sstream>

#include <sstream>
using namespace std;

QString Stats_Manager::convertInt(int num)
{
   stringstream ss;
   ss << num;
   return ss.str();
}

You can also use some other ways to convert int to string, like

char numstr[21]; // enough to hold all numbers up to 64-bits
sprintf(numstr, "%d", age);
result = name + numstr;

check this!

If you want to use something similar to the JavaScript, you just need to convert to strings first:

Console.WriteLine(mon.ToString() + "." + da.ToString() + "." + yer.ToString());

But a (much) better way would be to use the format option:

Console.WriteLine("{0}.{1}.{2}", mon, da, yer);

// range()              0..10, step=1
// range(max)           0..max, step=1
// range(min,max)       min..max, step=1
// range(min,step,max)  min..max, step=step
// Use:
// console.log(...range(3));
// Array.from(range(5))
// [...range(100)]
// for (const v of range(1,10)) { ... 

function* range(...args) {
    let [min, step, max] = {
        0: [0, 1, 10],
        1: [0, args[0] >= 0 ? 1 : -1, args[0]],
        2: [args[0], args[1] >= args[0] ? 1 : -1, args[1]],
        3: args,
    }[args.length] || [];
    if (min === undefined) throw new SyntaxError("Too many arguments");
    let x = min;
    while (step >= 0 ? x < max : x > max) {
        yield x;
        x += step
    }
}
console.log(...range());      // 0 1 2 3 4 5 6 7 8 9
console.log(...range(3));     // 0 1 2
console.log(...range(2, 5));  // 2 3 4
console.log(...range(5, 2));  // 5 4 3
console.log(...range(3, -3)); // 3 2 1 0 -1 -2
console.log(...range(-3, 3)); // -3 -2 -1 0 1 2
console.log(...range(-5, -2));// -5 -4 -3
console.log(...range(-2, -5));// -2 -3 -4

Ok, I deleted my previous answer because finally it was not what willlangford was looking for, but I made my point that maybe we were all misunderstanding the question.

I also thought of the SELECT DISTINCT... thing at first, but it seemed too weird to me that someone needed to know how many people had a different number of pets than the rest... thats why I thought that maybe the question was not clear enough.

So, now that the real question meaning is clarified, making a subquery for this its quite an overhead, I would preferably use a GROUP BY clause.

Imagine you have the table customer_pets like this:

+-----------------------+
|  customer  |   pets   |
+------------+----------+
| customer1  |    2     |
| customer2  |    3     |
| customer3  |    2     |
| customer4  |    2     |
| customer5  |    3     |
| customer6  |    4     |
+------------+----------+

then

SELECT count(customer) AS num_customers, pets FROM customer_pets GROUP BY pets

would return:

+----------------------------+
|  num_customers  |   pets   |
+-----------------+----------+
|        3        |    2     |
|        2        |    3     |
|        1        |    4     |
+-----------------+----------+

as you need.

You can use a much simpler formula. I just created a new workbook to test it.

Column A = Date1 | Column B = Date2 | Column C = Date3

Highlight Column A and enter the conditional formatting formula:

=AND(A1>B1,A1<C1)

I don't know what "milliseconds and float seconds" means, but this should give you an idea:

#include <chrono>
#include <thread>
#include <iostream>

int main()
{
  auto then = std::chrono::system_clock::now();
  std::this_thread::sleep_for(std::chrono::seconds(1));
  auto now = std::chrono::system_clock::now();
  auto dur = now - then;
  typedef std::chrono::duration<float> float_seconds;
  auto secs = std::chrono::duration_cast<float_seconds>(dur);
  std::cout << secs.count() << '\n';
}

import json

url = 'http://maps.googleapis.com/maps/api/directions/json?origin=Chicago,IL&destination=Los+Angeles,CA&waypoints=Joplin,MO|Oklahoma+City,OK&sensor=false'
result = json.load(urllib.urlopen(url))

I personally don't see the need for a library for this. Looking at http://caniuse.com/#feat=clipboard it's pretty widely supported now, however you can still do things like checking to see if the functionality exists in the current client and simply hide the copy button if it doesn't.

import React from 'react';

class CopyExample extends React.Component {

  constructor(props) {
    super(props);

    this.state = { copySuccess: '' }
  }

  copyToClipboard = (e) => {
    this.textArea.select();
    document.execCommand('copy');
    // This is just personal preference.
    // I prefer to not show the whole text area selected.
    e.target.focus();
    this.setState({ copySuccess: 'Copied!' });
  };

  render() {
    return (
      <div>
        {
         /* Logical shortcut for only displaying the 
            button if the copy command exists */
         document.queryCommandSupported('copy') &&
          <div>
            <button onClick={this.copyToClipboard}>Copy</button> 
            {this.state.copySuccess}
          </div>
        }
        <form>
          <textarea
            ref={(textarea) => this.textArea = textarea}
            value='Some text to copy'
          />
        </form>
      </div>
    );
  }

}
    
export default CopyExample;

Update: Rewritten using React Hooks in React 16.7.0-alpha.0

import React, { useRef, useState } from 'react';

export default function CopyExample() {

  const [copySuccess, setCopySuccess] = useState('');
  const textAreaRef = useRef(null);

  function copyToClipboard(e) {
    textAreaRef.current.select();
    document.execCommand('copy');
    // This is just personal preference.
    // I prefer to not show the whole text area selected.
    e.target.focus();
    setCopySuccess('Copied!');
  };

  return (
    <div>
      {
       /* Logical shortcut for only displaying the 
          button if the copy command exists */
       document.queryCommandSupported('copy') &&
        <div>
          <button onClick={copyToClipboard}>Copy</button> 
          {copySuccess}
        </div>
      }
      <form>
        <textarea
          ref={textAreaRef}
          value='Some text to copy'
        />
      </form>
    </div>
  );
}

import codecs

decode_hex = codecs.getdecoder("hex_codec")

# for an array
msgs = [decode_hex(msg)[0] for msg in msgs]

# for a string
string = decode_hex(string)[0]

The line starting ALREADYEXISTS uses ’ as the closing quote, it should be using '. The open quote on the next line (where the error is reported) is seen as the closing quote, and this mix up is causing the error.

adjustcolor("blanchedalmond",alpha.f = 0.3)

The above function provides a color code which corresponds to a transparent version of the input color (In this case the input color is "blanchedalmond.").

Input alpha values range on a scale of 0 to 1, 0 being completely transparent and 1 being completely opaque. (In this case, the code for the translucent shad of "blanchedalmond" given an alpha of .3 is "#FFEBCD4D." Be sure to include the hashtag symbol). You can make the new translucent color into the background color by using this function provided by joran earlier in this thread:

rect(par("usr")[1],par("usr")[3],par("usr")[2],par("usr")[4],col = "blanchedalmond")

By using a translucent color, you can be sure that the graph's data can still be seen underneath after the background color is applied. Hope this helps!

I had that problem too and I solve it by:

$today = date("Ymd");
$expire = str_replace('-', '', $row->expireDate); //from db

if(($today - $expire) > $NUMBER_OF_DAYS) 
{ 
    //do something; 
}

I got same error while installing termcolor and I fixed it by reinstalling it .

The poor mans compromise solution is to use a simplistic multi signature approach.

For Example the DBA sets the applications database password to a 50 character random string. TAKqWskc4ncvKaJTyDcgAHq82X7tX6GfK2fc386bmNw3muknjU

He or she give half the password to the application developer who then hard codes it into the java binary.

private String pass1 = "TAKqWskc4ncvKaJTyDcgAHq82"

The other half of the password is passed as a command line argument. the DBA gives pass2 to the system support or admin person who either enters it a application start time or puts it into the automated application start up script.

java -jar /myapplication.jar -pass2 X7tX6GfK2fc386bmNw3muknjU

When the application starts it uses pass1 + pass2 and connects to the database.

This solution has many advantages with out the downfalls mentioned.

You can safely put half the password in a command line arguments as reading it wont help you much unless you are the developer who has the other half of the password.

The DBA can also still change the second half of the password and the developer need not have to re-deploy the application.

The source code can also be semi public as reading it and the password will not give you application access.

You can further improve the situation by adding restrictions on the IP address ranges the database will accept connections from.

This seems to work fine:

<button onclick="location.href='mailto:[email protected]';">send mail</button>

Transparent background will help you see what behind the element, in this case what behind your td is in fact the parent table. So we have no way to achieve what you want using pure CSS. Even using script can't solve it in a direct way. We can just have a workaround using script based on the idea of using the same background for both the body and the td. However we have to update the background-position accordingly whenver the window is resized. Here is the code you can use with the default background position of body (which is left top, otherwise you have to change the code to update the background-position of the td correctly):

HTML:

<table id = "MainTable">
 <tr> 
    <td width = "20%"></td>
    <td width = "80%" id='test'>
      <table>
        <tr><td>something interesting here</td></tr>
        <tr><td>another thing also interesting out there</td></tr>
      </table>
    </td>
 </tr>
</table>

CSS:

/* use the same background for the td #test and the body */
#test {
  padding:40px;
  background:url('http://placekitten.com/800/500');    
}
body {
  background:url('http://placekitten.com/800/500');
}    

JS (better use jQuery):

//code placed in onload event handler
function updateBackgroundPos(){
  var pos = $('#test').offset();
  $('#test').css('background-position', 
                            -pos.left + 'px' + " " + (-pos.top + 'px'));
};
updateBackgroundPos();
$(window).resize(updateBackgroundPos);

Demo.

Try resizing the viewport, you'll see the background-position updated correctly, which will make an effect looking like the background of the td is transparent to the body.

arr.reduce((o, [key, value]) => ({...o, [key]: value}), {})

A large number of unwanted NUL characters, say one every other byte, indicates that the file is encoded in UTF-16 and that you should use iconv to convert it to UTF-8.

cout << "Enter amount of spaces you would like (integer)" << endl; 
cin >> n;
//print n spaces
for (int i = 0; i < n; ++i)
{
   cout << " " ;
}
cout <<endl;

Another way of accomplishing this is using animation which provides more control.

#content #nav a {
    background-color: #FF0;
    
    /* only animation-duration here is required, rest are optional (also animation-name but it will be set on hover)*/
    animation-duration: 1s; /* same as transition duration */
    animation-timing-function: linear; /* kind of same as transition timing */
    animation-delay: 0ms; /* same as transition delay */
    animation-iteration-count: 1; /* set to 2 to make it run twice, or Infinite to run forever!*/
    animation-direction: normal; /* can be set to "alternate" to run animation, then run it backwards.*/
    animation-fill-mode: none; /* can be used to retain keyframe styling after animation, with "forwards" */
    animation-play-state: running; /* can be set dynamically to pause mid animation*/
    
    /* declaring the states of the animation to transition through */
    /* optionally add other properties that will change here, or new states (50% etc) */
    @keyframes onHoverAnimation {
    0% {
      background-color: #FF0;  
    }
    100% {
      background-color: #AD310B;
    }
  }
}

#content #nav a:hover {
    /* animation wont run unless the element is given the name of the animation. This is set on hover */
    animation-name: onHoverAnimation;
}

Can use either json or ast python modules:

Using json :
=============

import json
jsonStr = '{"one" : "1", "two" : "2", "three" : "3"}'
json_data = json.loads(jsonStr)
print(f"json_data: {json_data}")
print(f"json_data['two']: {json_data['two']}")

Output:
json_data: {'one': '1', 'two': '2', 'three': '3'}
json_data['two']: 2




Using ast:
==========

import ast
jsonStr = '{"one" : "1", "two" : "2", "three" : "3"}'
json_dict = ast.literal_eval(jsonStr)
print(f"json_dict: {json_dict}")
print(f"json_dict['two']: {json_dict['two']}")

Output:
json_dict: {'one': '1', 'two': '2', 'three': '3'}
json_dict['two']: 2

My web host is stuck on version 5.1 of mysql so anyone like me that doesn't have the option of upgrading can follow these directions:

In this line ...

if (*message == "\0") {

... as you can see in the warning ...

warning: comparison between pointer and integer
      ('int' and 'char *')

... you are actually comparing an int with a char *, or more specifically, an int with an address to a char.

To fix this, use one of the following:

if(*message == '\0') ...
if(message[0] == '\0') ...
if(!*message) ...

On a side note, if you'd like to compare strings you should use strcmp or strncmp, found in string.h.

When I needed HTML to PDF conversion earlier this year, I tried the trial of Winnovative HTML to PDF converter (I think ExpertPDF is the same product, too). It worked great so we bought a license at that company. I don't go into it too in depth after that.

To work with NpgsqlCommand or the standard sqlCommand use:

int result = int.Parse(cmd.ExecuteScalar().ToString());

If your webhost allows it, or you will need to deal with sensitive data, then use HTTPS, period. (It's often required by the law afaik).

Otherwise if you want to do something over HTTP. I would do something like this.

1. The server embeds its public key into the login page.
2. The client populates the login form and clicks submit.
3. An AJAX request gets the current timestamp from the server.
4. Client side script concatenates the credentials, the timestamp and a salt (hashed from analog data eg. mouse movements, key press events), encrypts it using the public key.
5. Submits the resulting hash.
6. Server decrypts the hash
7. Checks if the timestamp is recent enough (allows a short 5-10 second window only). Rejects the login if the timestamp is too old.
8. Stores the hash for 20 seconds. Rejects the same hash for login during this interval.
9. Authenticates the user.

So this way the password is protected and the same authentication hash cannot be replayed.

About the security of the session token. That's a bit harder. But it's possible to make reusing a stolen session token a bit harder.

1. The server sets an extra session cookie which contains a random string.
2. The browser sends back this cookie on the next request.
3. The server checks the value in the cookie, if it's different then it destroys the session, otherwise all is okay.
4. The server sets the cookie again with different text.

So if the session token got stolen, and a request is sent up by someone else, then on the original user's next request the session will be destroyed. So if the user actively browsing the site, clicking on links often, then the thief won't go far with the stolen token. This scheme can be fortified by requiring another authentication for the sensitive operations (like account deletion).

EDIT: Please note this doesn't prevent MITM attacks if the attacker sets up their own page with a different public key and proxies requests to the server. To protect against this the public key must be pinned in the browser's local storage or within the app to detect these kind of tricks.

About the implementation: RSA is probably to most known algorithm, but it's quite slow for long keys. I don't know how fast a PHP or Javascript implementation of would be. But probably there are a faster algorithms.

In C, you can use the built in qsort command:

int compare( const void* a, const void* b)
{
     int int_a = * ( (int*) a );
     int int_b = * ( (int*) b );

     if ( int_a == int_b ) return 0;
     else if ( int_a < int_b ) return -1;
     else return 1;
}

qsort( a, 6, sizeof(int), compare )

see: http://www.cplusplus.com/reference/clibrary/cstdlib/qsort/

To answer the second part of your question: an optimal (comparison based) sorting algorithm is one that runs with O(n log(n)) comparisons. There are several that have this property (including quick sort, merge sort, heap sort, etc.), but which one to use depends on your use case.

As a side note, you can sometime do better than O(n log(n)) if you know something about your data - see the wikipedia article on Radix Sort

Sure, use the .format method. E.g.,

print('{:10s} {:3d}  {:7.2f}'.format('xxx', 123, 98))
print('{:10s} {:3d}  {:7.2f}'.format('yyyy', 3, 1.0))
print('{:10s} {:3d}  {:7.2f}'.format('zz', 42, 123.34))

will print

xxx        123    98.00
yyyy         3     1.00
zz          42   123.34

You can adjust the field sizes as desired. Note that .format works independently of print to format a string. I just used print to display the strings. Brief explanation:

10s format a string with 10 spaces, left justified by default

3d format an integer reserving 3 spaces, right justified by default

7.2f format a float, reserving 7 spaces, 2 after the decimal point, right justfied by default.

There are many additional options to position/format strings (padding, left/right justify etc), String Formatting Operations will provide more information.

Update for f-string mode. E.g.,

text, number, other_number = 'xxx', 123, 98
print(f'{text:10} {number:3d}  {other_number:7.2f}')

For right alignment

print(f'{text:>10} {number:3d}  {other_number:7.2f}')

jQuery('#testID2').find('.test2').replaceWith('.test3');

Semantically, you are selecting the element with the ID testID2, then you are looking for any descendent elements with the class test2 (does not exist) and then you are replacing that element with another element (elements anywhere in the page with the class test3) that also do not exist.

You need to do this:

jQuery('#testID2').addClass('test3').removeClass('test2');

This selects the element with the ID testID2, then adds the class test3 to it. Last, it removes the class test2 from that element.

Kotlin's way -

fun Context.bitMapFromImgUrl(imageUrl: String, callBack: (bitMap: Bitmap) -> Unit) {
    GlideApp.with(this)
        .asBitmap()
        .load(imageUrl)
        .into(object : CustomTarget<Bitmap>() {
            override fun onResourceReady(resource: Bitmap, transition: Transition<in Bitmap>?) {
                callBack(resource)
            }

            override fun onLoadCleared(placeholder: Drawable?) {
                // this is called when imageView is cleared on lifecycle call or for
                // some other reason.
                // if you are referencing the bitmap somewhere else too other than this imageView
                // clear it here as you can no longer have the bitmap
            }
        })
}

You can find all of those operators in the Python language reference, though you'll have to scroll around a bit to find them all. As other answers have said:

• The ** operator does exponentiation. a ** b is a raised to the b power. The same ** symbol is also used in function argument and calling notations, with a different meaning (passing and receiving arbitrary keyword arguments).
• The ^ operator does a binary xor. a ^ b will return a value with only the bits set in a or in b but not both. This one is simple!
• The % operator is mostly to find the modulus of two integers. a % b returns the remainder after dividing a by b. Unlike the modulus operators in some other programming languages (such as C), in Python a modulus it will have the same sign as b, rather than the same sign as a. The same operator is also used for the "old" style of string formatting, so a % b can return a string if a is a format string and b is a value (or tuple of values) which can be inserted into a.
• The // operator does Python's version of integer division. Python's integer division is not exactly the same as the integer division offered by some other languages (like C), since it rounds towards negative infinity, rather than towards zero. Together with the modulus operator, you can say that a == (a // b)*b + (a % b). In Python 2, floor division is the default behavior when you divide two integers (using the normal division operator /). Since this can be unexpected (especially when you're not picky about what types of numbers you get as arguments to a function), Python 3 has changed to make "true" (floating point) division the norm for division that would be rounded off otherwise, and it will do "floor" division only when explicitly requested. (You can also get the new behavior in Python 2 by putting from __future__ import division at the top of your files. I strongly recommend it!)

For those of you who hasn't seen one valid argument against use of Thread.Sleep in SCENARIO 2, there really is one - application exit be held up by the while loop (SCENARIO 1/3 is just plain stupid so not worthy of more mentioning)

Many who pretend to be in-the-know, screaming Thread.Sleep is evil failed to mentioned a single valid reason for those of us who demanded a practical reason not to use it - but here it is, thanks to Pete - Thread.Sleep is Evil (can be easily avoided with a timer/handler)

    static void Main(string[] args)
    {
        Thread t = new Thread(new ThreadStart(ThreadFunc));
        t.Start();

        Console.WriteLine("Hit any key to exit.");
        Console.ReadLine();

        Console.WriteLine("App exiting");
        return;
    }

    static void ThreadFunc()
    {
        int i=0;
        try
        {
            while (true)
            {
                Console.WriteLine(Thread.CurrentThread.ThreadState.ToString() + " " + i);

                Thread.Sleep(1000 * 10);
                i++;
            }
        }
        finally
        {
            Console.WriteLine("Exiting while loop");
        }
        return;
    }

Sorry for necro. I have too run into the same issue and found out that rJava expects JAVA_HOME to point to JRE. If you have JDK installed, most probably your JAVA_HOME points to JDK. My quick solution:

Sys.setenv(JAVA_HOME=paste(Sys.getenv("JAVA_HOME"), "jre", sep="\\"))

you can do this as below in typescript

 const _params = {} as any;

 _params.name ='nazeh abel'

since typescript does not behave like javascript so we have to make the type as any otherwise it won't allow you to assign property dynamically to an object

moment.js

convert timestamps to date string in js

https://momentjs.com/

moment().format('YYYY-MM-DD hh:mm:ss');
// "2020-01-10 11:55:43"

moment(1578478211000).format('YYYY-MM-DD hh:mm:ss');
// "2020-01-08 06:10:11"

strtotime expects a standard date format, and passes back a timestamp.

You seem to be passing strtotime a single digit to output a date format from.

You should be using mktime which takes the date elements as parameters.

Your full code:

$monthNum = sprintf("%02s", $result["month"]);
$monthName = date("F", mktime(null, null, null, $monthNum));

echo $monthName;

However, the mktime function does not require a leading zero to the month number, so the first line is completely unnecessary, and $result["month"] can be passed straight into the function.

This can then all be combined into a single line, echoing the date inline.

Your refactored code:

echo date("F", mktime(null, null, null, $result["month"], 1));

...

As mentioned by others, this is because the loader can't be found, not your executable file. Unfortunately the message is not clear enough.

You can fix it by changing the loader that your executable uses, see my thorough answer in this other question: Multiple glibc libraries on a single host

Basically you have to find which loader it's trying to use:

$ readelf -l arm-mingw32ce-g++ | grep interpreter
  [Requesting program interpreter: /lib/ld-linux.so.2]

Then find the right path for an equivalent loader, and change your executable to use the loader from the path that it really is:

$ ./patchelf --set-interpreter /path/to/newglibc/ld-linux.so.2 arm-mingw32ce-g++

You will probably need to set the path of the includes too, you will know if you want it or not after you try to run it. See all the details in that other thread.

Often enterprise databases have several users and I'm not aways on the right one :

SELECT * FROM ALL_CONSTRAINTS WHERE table_name = 'YOUR TABLE NAME' ;

Picked from Oracle documentation

In my Controller, I merely added an HttpServletResponse parameter and manually added the headers, no filter or intercept required and it works fine:

httpServletResponse.setHeader("Access-Control-Allow-Origin", "*");
httpServletResponse.setHeader("Access-Control-Allow-Methods", "GET, OPTIONS");
httpServletResponse.setHeader("Access-Control-Allow-Headers","Origin, X-Requested-With, Content-Type, Accept, X-Auth-Token, X-Csrf-Token, WWW-Authenticate, Authorization");
httpServletResponse.setHeader("Access-Control-Allow-Credentials", "false");
httpServletResponse.setHeader("Access-Control-Max-Age", "3600");

Give something like this a try:

$(document).ready(function(){
    $("#thisTable tr").click(function(){
        $(this).find("td").each(function(){
            alert($(this).html());
        });
    });
});?

Here is a fiddle of the code in action: http://jsfiddle.net/YhZsW/

That depends on what type your list is, for ArrayList use:

list.get(0);

for LinkedList use:

list.getFirst();

if you like the array approach:

list.toArray()[0];

You can open up terminal and simply type

java -version // this will check your jre version
javac -version // this will check your java compiler version if you installed 

this should show you the version of java installed on the system (assuming that you have set the path of the java in system environment).

And if you haven't, add it via

export JAVA_HOME=/path/to/java/jdk1.x

and if you unsure if you have java at all on your system just use find in terminal

i.e. find / -name "java"

If you would like nicely auto-formatted code. Try CTRL + A + K + F. While holding down CTRL hit a, then k, then f.

My application failed to start via "Task Scheduler".

The error in "Event Viewer" is: System.IO.DirectoryNotFoundException

The "Task Scheduler" tries to run this application with the "SYSTEM" user. The problem was that a "network drive" was not mapped for the "SYSTEM" user. So what I did was, I created a ".bat" file and mapped the "network drive" before starting the application:

net use T: \\172.20.2.215\images
cd C:\MyApplication
start MyApplication.exe

So check your logs first: "Event Viewer" -> Windows Logs -> Application

Add any file in the documentation which will include your content, for example toc.h:

@ mainpage Manual SDK
<hr/>
@ section pageTOC Content
  -# @ref Description
  -# @ref License
  -# @ref Item
...

And in your Doxyfile:

INPUT = toc.h \

Example (in Russian):

• scale-tech.ru/luckyBackupW/doc/html/index.html (via web.archive.org)

• scale-tech.ru/luckyBackupW/doc/html/toc_8h_source.html (via web.archive.org)

Just to add to the other answers, the documentation gives this explanation:

• KEY is normally a synonym for INDEX. The key attribute PRIMARY KEY can also be specified as just KEY when given in a column definition. This was implemented for compatibility with other database systems.

• A UNIQUE index creates a constraint such that all values in the index must be distinct. An error occurs if you try to add a new row with a key value that matches an existing row. For all engines, a UNIQUE index permits multiple NULL values for columns that can contain NULL.

• A PRIMARY KEY is a unique index where all key columns must be defined as NOT NULL. If they are not explicitly declared as NOT NULL, MySQL declares them so implicitly (and silently). A table can have only one PRIMARY KEY. The name of a PRIMARY KEY is always PRIMARY, which thus cannot be used as the name for any other kind of index.

Important to note with elementFormDefault is that it applies to locally defined elements, typically named elements inside a complexType block, as opposed to global elements defined on the top-level of the schema. With elementFormDefault="qualified" you can address local elements in the schema from within the xml document using the schema's target namespace as the document's default namespace.

In practice, use elementFormDefault="qualified" to be able to declare elements in nested blocks, otherwise you'll have to declare all elements on the top level and refer to them in the schema in nested elements using the ref attribute, resulting in a much less compact schema.

This bit in the XML Schema Primer talks about it: http://www.w3.org/TR/xmlschema-0/#NS

Using HTML 5.0, it is possible to fix width of text block using <span> or <div>.

For <span>, what is important is to add following CCS line

display: inline-block;

For your empty <span> what is important is to add   space.

My code is following

I think you are looking for this

String[] car = new String[10];
int size = car.length;

If you are in the U.S. Pacific time zone, then the epoch for you is 4 p.m. on December 31, 1969. You added the milliseconds since the epoch to

new DateTime(1970, 01, 01)

which, since it did not have a timezone, was interpreted as being in your timezone.

There is nothing really wrong with thinking of instants in time as milliseconds since the epoch but understand the epoch is only 1970-01-01T00:00:00Z.

You can't think of instants in times, when represented as dates, without timezones.

Another solution which works in Python 2 and 3:

#foo.py
import sys

class Foo(object):
    pass

def print_classes():
    current_module = sys.modules[__name__]
    for key in dir(current_module):
        if isinstance( getattr(current_module, key), type ):
            print(key)

# test.py
import foo
foo.print_classes()

You can implement a middleware which handles Basic authentication.

public async Task Invoke(HttpContext context)
{
    var authHeader = context.Request.Headers.Get("Authorization");
    if (authHeader != null && authHeader.StartsWith("basic", StringComparison.OrdinalIgnoreCase))
    {
        var token = authHeader.Substring("Basic ".Length).Trim();
        System.Console.WriteLine(token);
        var credentialstring = Encoding.UTF8.GetString(Convert.FromBase64String(token));
        var credentials = credentialstring.Split(':');
        if(credentials[0] == "admin" && credentials[1] == "admin")
        {
            var claims = new[] { new Claim("name", credentials[0]), new Claim(ClaimTypes.Role, "Admin") };
            var identity = new ClaimsIdentity(claims, "Basic");
            context.User = new ClaimsPrincipal(identity);
        }
    }
    else
    {
        context.Response.StatusCode = 401;
        context.Response.Headers.Set("WWW-Authenticate", "Basic realm=\"dotnetthoughts.net\"");
    }
    await _next(context);
}

This code is written in a beta version of asp.net core. Hope it helps.

If your using parse_ini_file($file) or a routine is rading an .ini file, check if you data is quoted in the ini file. Unquoted data will cause this error. Ex; data1=test will cause the error, data1="test" will not.

My case: Seeing the same INFO message.

Centos 6.2 x86_64 Tomcat 6.0.24

This fixed the problem for me:

yum install tomcat-native

boom!

In case you want a quicker (but still very clean) way of achieving it for a personal purpose (for instance if you want to build a specific project having some strong requirements concerning the version of the compiler), just follow the following steps:

• type echo $PATH and look for a personal directory having a very high priority (in my case, I have ~/.local/bin);
• add the symbolic links in this directory:

For instance:

ln -s /usr/bin/gcc-WHATEVER ~/.local/bin/gcc
ln -s /usr/bin/g++-WHATEVER ~/.local/bin/g++

Of course, this will work for a single user (it isn't a system wide solution), but on the other hand I don't like to change too many things in my installation.

I got it!

$dur = file_get_contents("https://www.googleapis.com/youtube/v3/videos?part=contentDetails&id=$vId&key=dldfsd981asGhkxHxFf6JqyNrTqIeJ9sjMKFcX4");

$duration = json_decode($dur, true);
foreach ($duration['items'] as $vidTime) {
    $vTime= $vidTime['contentDetails']['duration'];
}

There it returns the time for YouTube API version 3 (the key is made up by the way ;). I used $vId that I had gotten off of the returned list of the videos from the channel I am showing the videos from...

It works. Google REALLY needs to include the duration in the snippet so you can get it all with one call instead of two... it's on their 'wontfix' list.

my solution inspired from Aras Alenin answer above where I added one level of object comparison and a custom object for comparison results. I am also interested to get property name with object name:

    public static IEnumerable<ObjectPropertyChanged> GetPublicSimplePropertiesChanged<T>(this T previous, T proposedChange,
     string[] namesOfPropertiesToBeIgnored) where T : class
    {
        return GetPublicGenericPropertiesChanged(previous, proposedChange, namesOfPropertiesToBeIgnored, true, null, null);
    }

    public static IReadOnlyList<ObjectPropertyChanged> GetPublicGenericPropertiesChanged<T>(this T previous, T proposedChange,
        string[] namesOfPropertiesToBeIgnored) where T : class
    {
        return GetPublicGenericPropertiesChanged(previous, proposedChange, namesOfPropertiesToBeIgnored, false, null, null);
    }

    /// <summary>
    /// Gets the names of the public properties which values differs between first and second objects.
    /// Considers 'simple' properties AND for complex properties without index, get the simple properties of the children objects.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="previous">The previous object.</param>
    /// <param name="proposedChange">The second object which should be the new one.</param>
    /// <param name="namesOfPropertiesToBeIgnored">The names of the properties to be ignored.</param>
    /// <param name="simpleTypeOnly">if set to <c>true</c> consider simple types only.</param>
    /// <param name="parentTypeString">The parent type string. Meant only for recursive call with simpleTypeOnly set to <c>true</c>.</param>
    /// <param name="secondType">when calling recursively, the current type of T must be clearly defined here, as T will be more generic (using base class).</param>
    /// <returns>
    /// the names of the properties
    /// </returns>
    private static IReadOnlyList<ObjectPropertyChanged> GetPublicGenericPropertiesChanged<T>(this T previous, T proposedChange,
        string[] namesOfPropertiesToBeIgnored, bool simpleTypeOnly, string parentTypeString, Type secondType) where T : class
    {
        List<ObjectPropertyChanged> propertiesChanged = new List<ObjectPropertyChanged>();

        if (previous != null && proposedChange != null)
        {
            var type = secondType == null ? typeof(T) : secondType;
            string typeStr = parentTypeString + type.Name + ".";
            var ignoreList = namesOfPropertiesToBeIgnored.CreateList();
            IEnumerable<IEnumerable<ObjectPropertyChanged>> genericPropertiesChanged =
                from pi in type.GetProperties(BindingFlags.Public | BindingFlags.Instance)
                where !ignoreList.Contains(pi.Name) && pi.GetIndexParameters().Length == 0 
                    && (!simpleTypeOnly || simpleTypeOnly && pi.PropertyType.IsSimpleType())
                let firstValue = type.GetProperty(pi.Name).GetValue(previous, null)
                let secondValue = type.GetProperty(pi.Name).GetValue(proposedChange, null)
                where firstValue != secondValue && (firstValue == null || !firstValue.Equals(secondValue))
                let subPropertiesChanged = simpleTypeOnly || pi.PropertyType.IsSimpleType()
                    ? null
                    : GetPublicGenericPropertiesChanged(firstValue, secondValue, namesOfPropertiesToBeIgnored, true, typeStr, pi.PropertyType)
                let objectPropertiesChanged = subPropertiesChanged != null && subPropertiesChanged.Count() > 0
                    ? subPropertiesChanged
                    : (new ObjectPropertyChanged(proposedChange.ToString(), typeStr + pi.Name, firstValue.ToStringOrNull(), secondValue.ToStringOrNull())).CreateList()
                select objectPropertiesChanged;

            if (genericPropertiesChanged != null)
            {   // get items from sub lists
                genericPropertiesChanged.ForEach(a => propertiesChanged.AddRange(a));
            }
        }
        return propertiesChanged;
    }

Using the following class to store comparison results

[System.Serializable]
public class ObjectPropertyChanged
{
    public ObjectPropertyChanged(string objectId, string propertyName, string previousValue, string changedValue)
    {
        ObjectId = objectId;
        PropertyName = propertyName;
        PreviousValue = previousValue;
        ProposedChangedValue = changedValue;
    }

    public string ObjectId { get; set; }

    public string PropertyName { get; set; }

    public string PreviousValue { get; set; }

    public string ProposedChangedValue { get; set; }
}

And a sample unit test:

    [TestMethod()]
    public void GetPublicGenericPropertiesChangedTest1()
    {
        // Define objects to test
        Function func1 = new Function { Id = 1, Description = "func1" };
        Function func2 = new Function { Id = 2, Description = "func2" };
        FunctionAssignment funcAss1 = new FunctionAssignment
        {
            Function = func1,
            Level = 1
        };
        FunctionAssignment funcAss2 = new FunctionAssignment
        {
            Function = func2,
            Level = 2
        };

        // Main test: read properties changed
        var propertiesChanged = Utils.GetPublicGenericPropertiesChanged(funcAss1, funcAss2, null);

        Assert.IsNotNull(propertiesChanged);
        Assert.IsTrue(propertiesChanged.Count == 3);
        Assert.IsTrue(propertiesChanged[0].PropertyName == "FunctionAssignment.Function.Description");
        Assert.IsTrue(propertiesChanged[1].PropertyName == "FunctionAssignment.Function.Id");
        Assert.IsTrue(propertiesChanged[2].PropertyName == "FunctionAssignment.Level");
    }

I believe the best way to do this is to use the LocalTimezone class defined in the datetime.tzinfo documentation (goto http://docs.python.org/library/datetime.html#tzinfo-objects and scroll down to the "Example tzinfo classes" section):

Assuming Local is an instance of LocalTimezone

t = datetime.datetime(2009, 7, 10, 18, 44, 59, 193982, tzinfo=utc)
local_t = t.astimezone(Local)

then str(local_t) gives:

'2009-07-11 04:44:59.193982+10:00'

which is what you want.

(Note: this may look weird to you because I'm in New South Wales, Australia which is 10 or 11 hours ahead of UTC)

The problem is that you aren't correctly escaping the input string, try:

echo "\"member\":\"time\"" | grep -e "member\""

Alternatively, you can use unescaped double quotes within single quotes:

echo '"member":"time"' | grep -e 'member"'

It's a matter of preference which you find clearer, although the second approach prevents you from nesting your command within another set of single quotes (e.g. ssh 'cmd').

PhpStorm supports all the features of WebStorm but some are not bundled so you might need to install the corresponding plugin for some framework via Settings > Plugins > Install JetBrains Plugin.

I found the nice resource Standard C++ Containers. Probably this is what you all looking for.

VECTOR

Constructors

vector<T> v;              Make an empty vector.                                     O(1)

v.push_back(value)         Add value to end.                                                O(1) (amortized)
v.insert(iterator, value)  Insert value at the position indexed by iterator.                O(n)
v.pop_back()               Remove value from end.                                           O(1)
v.assign(begin, end)       Clear the container and copy in the elements from begin to end.  O(n)
v.erase(iterator)          Erase value indexed by iterator.                                 O(n)
v.erase(begin, end)        Erase the elements from begin to end.                            O(n)

For other containers, refer to the page.

A common trick is to check like this:

trim(TextBox1.Value & vbnullstring) = vbnullstring

this will work for spaces, empty strings, and genuine null values

The return value of the function should be the number of unique elements and they are all stored at the front of the array. Without this additional information, you won't even know if there were any duplicates.

Each iteration of the outer loop processes one element of the array. If it is unique, it stays in the front of the array and if it is a duplicate, it is overwritten by the last unprocessed element in the array. This solution runs in O(n^2) time.

#include <stdio.h>
#include <stdlib.h>

size_t rmdup(int *arr, size_t len)
{
  size_t prev = 0;
  size_t curr = 1;
  size_t last = len - 1;
  while (curr <= last) {
    for (prev = 0; prev < curr && arr[curr] != arr[prev]; ++prev);
    if (prev == curr) {
      ++curr;
    } else {
      arr[curr] = arr[last];
      --last;
    }
  }
  return curr;
}

void print_array(int *arr, size_t len)
{
  printf("{");
  size_t curr = 0;
  for (curr = 0; curr < len; ++curr) {
    if (curr > 0) printf(", ");
    printf("%d", arr[curr]);
  }
  printf("}");
}

int main()
{
  int arr[] = {4, 8, 4, 1, 1, 2, 9};
  printf("Before: ");
  size_t len = sizeof (arr) / sizeof (arr[0]);
  print_array(arr, len);
  len = rmdup(arr, len);
  printf("\nAfter: ");
  print_array(arr, len);
  printf("\n");
  return 0;
}

You can use RETURN to stop execution of a stored procedure immediately. Quote taken from Books Online:

Exits unconditionally from a query or procedure. RETURN is immediate and complete and can be used at any point to exit from a procedure, batch, or statement block. Statements that follow RETURN are not executed.

Out of paranoia, I tried yor example and it does output the PRINTs and does stop execution immediately.

I installed it on macOS and had to:

cd /Applications/Postgres.app/Contents/Versions/9.5/bin
createuser -U postgres -s YOURUSERNAME
createdb YOURUSERNAME

Try

This works in both SQL 2005 and 2008:

declare @source varbinary(max);
set @source = 0x21232F297A57A5A743894A0E4A801FC3;
select cast('' as xml).value('xs:hexBinary(sql:variable("@source"))', 'varchar(max)');

If you want to execute your Python script in PHP, it's necessary to do this command in your php script:

exec('your script python.py')

First step get container id:

docker ps

This will show you something like

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

1170fe9e9460 localhost:5000/python:env-7e847468c4d73a0f35e9c5164046ad88 "./run_notebook.sh" 26 seconds ago Up 25 seconds 0.0.0.0:8989->9999/tcp SLURM_TASK-303337_0

1170fe9e9460 is the container id in this case.

Second, enter the docker :

docker exec -it [container_id] bash

so in the above case: docker exec -it 1170fe9e9460 bash

You are part right. with <b>title</b> it looks fine, but I would like to use <h4>.

I have put <h4 style="display: inline;"> and it seams to work.

Now, I only need to add some vertival align.

Yes, there is: you can capture the echoed text using ob_start:

<?php function TestBlockHTML($replStr) {
    ob_start(); ?>
    <html>
    <body><h1><?php echo($replStr) ?></h1>
    </html>
<?php
    return ob_get_clean();
} ?>

If your constraint is on a user type, then don't forget to see if there is a Default Constraint, usually something like DF__TableName__ColumnName__6BAEFA67, if so then you will need to drop the Default Constraint, like this:

ALTER TABLE TableName DROP CONSTRAINT [DF__TableName__ColumnName__6BAEFA67]

For more info see the comments by the brilliant Aaron Bertrand on this answer.

if (!$("#myTextArea").val()) {
    // textarea is empty
}

You can also use $.trim to make sure the element doesn't contain only white-space:

if (!$.trim($("#myTextArea").val())) {
    // textarea is empty or contains only white-space
}

You can try this one to minify floating numbers

var n = 0.0000;
n = parseFloat(n.toString()); 

//output n = 0; 
// n = 3.14000; --> n = 3.14;

Yes, There is.

1. Create a new project and you should Shutdown The Android Studio Application.(Because it takes a long time for you).
2. Goto C:\Users\{Logged in User}\.gradle folder
3. There is a folder there that show you which version of gradle Android Studio requires (e.g. gradle-1.8-bin)
4. Download this version from internet (e.g. gradle-1.8-bin.zip).
5. Goto C:\Users\{Logged in User}\.gradle\wrapper\dists\gradle-1.8-bin
6. There is a folder here that its name is like a GUID.
7. You should just copy the zip file that you've already downloaded from internet into this folder.
8. Execute Android Studio and create a new project.

You could also do something as follow

public enum DAY {MON, TUES, WED, THU, FRI, SAT, SUN};
EnumSet.allOf(DAY.class).stream().map(e -> e.name()).collect(Collectors.toList())

or

EnumSet.allOf(DAY.class).stream().map(DAY::name).collect(Collectors.toList())

The main reason why I stumbled across this question is that I wanted to write a generic validator that validates whether a given string enum name is valid for a given enum type (Sharing in case anyone finds useful).

For the validation, I had to use Apache's EnumUtils library since the type of enum is not known at compile time.

@SuppressWarnings({ "unchecked", "rawtypes" })
public static void isValidEnumsValid(Class clazz, Set<String> enumNames) {
    Set<String> notAllowedNames = enumNames.stream()
            .filter(enumName -> !EnumUtils.isValidEnum(clazz, enumName))
            .collect(Collectors.toSet());

    if (notAllowedNames.size() > 0) {
        String validEnumNames = (String) EnumUtils.getEnumMap(clazz).keySet().stream()
            .collect(Collectors.joining(", "));

        throw new IllegalArgumentException("The requested values '" + notAllowedNames.stream()
                .collect(Collectors.joining(",")) + "' are not valid. Please select one more (case-sensitive) "
                + "of the following : " + validEnumNames);
    }
}

I was too lazy to write an enum annotation validator as shown in here https://stackoverflow.com/a/51109419/1225551

Sadly, many JSON C++ libraries have APIs that are non trivial to use, while JSON was intended to be easy to use.

So I tried jsoncpp from the gSOAP tools on the JSON doc shown in one of the answers above and this is the code generated with jsoncpp to construct a JSON object in C++ which is then written in JSON format to std::cout:

value x(ctx);
x["appDesc"]["description"] = "SomeDescription";
x["appDesc"]["message"] = "SomeMessage";
x["appName"]["description"] = "Home";
x["appName"]["message"] = "Welcome";
x["appName"]["imp"][0] = "awesome";
x["appName"]["imp"][1] = "best";
x["appName"]["imp"][2] = "good";
std::cout << x << std::endl;

and this is the code generated by jsoncpp to parse JSON from std::cin and extract its values (replace USE_VAL as needed):

value x(ctx);
std::cin >> x;
if (x.soap->error)
  exit(EXIT_FAILURE); // error parsing JSON
#define USE_VAL(path, val) std::cout << path << " = " << val << std::endl
if (x.has("appDesc"))
{
  if (x["appDesc"].has("description"))
    USE_VAL("$.appDesc.description", x["appDesc"]["description"]);
  if (x["appDesc"].has("message"))
    USE_VAL("$.appDesc.message", x["appDesc"]["message"]);
}
if (x.has("appName"))
{
  if (x["appName"].has("description"))
    USE_VAL("$.appName.description", x["appName"]["description"]);
  if (x["appName"].has("message"))
    USE_VAL("$.appName.message", x["appName"]["message"]);
  if (x["appName"].has("imp"))
  {
    for (int i2 = 0; i2 < x["appName"]["imp"].size(); i2++)
      USE_VAL("$.appName.imp[]", x["appName"]["imp"][i2]);
  }
}

This code uses the JSON C++ API of gSOAP 2.8.28. I don't expect people to change libraries, but I think this comparison helps to put JSON C++ libraries in perspective.

If the collection size is small you could go with the solution provided by rich.okelly. However, a large collection means that the generation of the dictionary may be noticeably slower than just searching the keys collection.

Also, if your usage scenario is searching for keys in different points in time, where the NameValueCollection may have been modified, generating the dictionary each time may, again, be slower than just searching the keys collection.

<?php if(!class_exists('PDO2')) {
    class PDO2 {
        private static $_instance;
        public static function getInstance() {
            if (!isset(self::$_instance)) {
                try {
                    self::$_instance = new PDO(
                        'mysql:host=***;dbname=***',
                        '***',
                        '***',
                        array(
                            PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8mb4 COLLATE utf8mb4_general_ci",
                            PDO::ATTR_ERRMODE            => PDO::ERRMODE_EXCEPTION
                        )
                    );
                } catch (PDOException $e) {
                    throw new PDOException($e->getMessage(), (int) $e->getCode());
                }
            }
            return self::$_instance;
        }
        public static function closeInstance() {
            return self::$_instance = null;
        }
    }
}
$req = PDO2::getInstance()->prepare('SELECT * FROM table');
$req->execute();
$count = $req->rowCount();
$results = $req->fetchAll(PDO::FETCH_ASSOC);
$req->closeCursor();
// Do other requests maybe
// And close connection
PDO2::closeInstance();
// print output

Full example, with custom class PDO2.

It works properly in FF 29, Opera 12.17, Chromium 34 and in IE9. Yes, it's a weird set of browsers!

Thanks to kind and patient help from golang-nuts, recipe is the following:

1) One needs to compile Go compiler for different target platforms and architectures. This is done from src folder in go installation. In my case Go installation is located in /usr/local/go thus to compile a compiler you need to issue make utility. Before doing this you need to know some caveats.

There is an issue about CGO library when cross compiling so it is needed to disable CGO library.

Compiling is done by changing location to source dir, since compiling has to be done in that folder

cd /usr/local/go/src

then compile the Go compiler:

sudo GOOS=windows GOARCH=386 CGO_ENABLED=0 ./make.bash --no-clean

You need to repeat this step for each OS and Architecture you wish to cross compile by changing the GOOS and GOARCH parameters.

If you are working in user mode as I do, sudo is needed because Go compiler is in the system dir. Otherwise you need to be logged in as super user. On Mac you may need to enable/configure SU access (it is not available by default), but if you have managed to install Go you possibly already have root access.

2) Once you have all cross compilers built, you can happily cross compile your application by using the following settings for example:

GOOS=windows GOARCH=386 go build -o appname.exe appname.go

GOOS=linux GOARCH=386 CGO_ENABLED=0 go build -o appname.linux appname.go

Change the GOOS and GOARCH to targets you wish to build.

If you encounter problems with CGO include CGO_ENABLED=0 in the command line. Also note that binaries for linux and mac have no extension so you may add extension for the sake of having different files. -o switch instructs Go to make output file similar to old compilers for c/c++ thus above used appname.linux can be any other extension.

To find all valid address list this is the code I have used

public static IEnumerable<string> GetAddresses()
{
      var host = Dns.GetHostEntry(Dns.GetHostName());
      return (from ip in host.AddressList where ip.AddressFamily == AddressFamily.lo select ip.ToString()).ToList();
}

Here's what I did to fix this:

1) Create a new project

2) open the gradle-wrapper.properties file and copy the distributionUrl to your project e.g.:

distributionUrl=https\://services.gradle.org/distributions/gradle-3.2-all.zip

3) open the build.gradle (Project) and copy the gradle dependency to your project e.g.:

classpath 'com.android.tools.build:gradle:2.3.0-beta1'

4) File --> Invalidate Caches / Restart (I think a re-sync may have sufficed, but didn't try it)

5) Delete that project you made (optional)

Look, this is a silly way to do things, but Android Studio is free so who am I to complain...

Sometimes this error occurs when the .ts file is not saved. So make sure all files in the project are saved otherwise try to restart the editor.

I did some modification to the SMNALLY's code so it can run in Python 3.5.2. This is my result:

#Import the following library to make use of the DispatchEx to run the macro
import win32com.client as wincl

def runMacro():

    if os.path.exists("C:\\Users\\Dev\\Desktop\\Development\\completed_apps\\My_Macr_Generates_Data.xlsm"):

    # DispatchEx is required in the newest versions of Python.
    excel_macro = wincl.DispatchEx("Excel.application")
    excel_path = os.path.expanduser("C:\\Users\\Dev\\Desktop\\Development\\completed_apps\\My_Macr_Generates_Data.xlsm")
    workbook = excel_macro.Workbooks.Open(Filename = excel_path, ReadOnly =1)
    excel_macro.Application.Run\
        ("ThisWorkbook.Template2G")
    #Save the results in case you have generated data
    workbook.Save()
    excel_macro.Application.Quit()  
    del excel_macro

For using FusedLocationProviderClient with Google Play Services 11 and higher:

see here: How to get current Location in GoogleMap using FusedLocationProviderClient

For using (now deprecated) FusedLocationProviderApi:

If your project uses Google Play Services 10 or lower, using the FusedLocationProviderApi is the optimal choice.

The FusedLocationProviderApi offers less battery drain than the old open source LocationManager API. Also, if you're already using Google Play Services for Google Maps, there's no reason not to use it.

Here is a full Activity class that places a Marker at the current location, and also moves the camera to the current position.

It also checks for the Location permission at runtime for Android 6 and later (Marshmallow, Nougat, Oreo). In order to properly handle the Location permission runtime check that is necessary on Android M/Android 6 and later, you need to ensure that the user has granted your app the Location permission before calling mGoogleMap.setMyLocationEnabled(true) and also before requesting location updates.

        GoogleApiClient.ConnectionCallbacks,

    GoogleMap mGoogleMap;
    SupportMapFragment mapFrag;

        mapFrag = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
        mapFrag.getMapAsync(this);
    }

    @Override
    public void onPause() {
        super.onPause();

        //stop location updates when Activity is no longer active
        if (mGoogleApiClient != null) {
            LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
        }
    }

Prompt the user for Location permission by calling ActivityCompat.requestPermissions():

Move camera to current location and place Marker when the Location permission is granted:

Don't know if anyone searches for this. I had the same problem. A select on the query and then doing the where (or join) and using the select variable solved the problem for me. (problem was in the collection "Reintegraties" for me)

query.Select(zv => new
            {
                zv,
                rId = zv.this.Reintegraties.FirstOrDefault().Id
            })
            .Where(x => !db.Taken.Any(t => t.HoortBijEntiteitId == x.rId
                                             && t.HoortBijEntiteitType == EntiteitType.Reintegratie
                                             && t.Type == TaakType))
            .Select(x => x.zv);

hope this helps anyone.

I don't think you can mount a Linux folder as a network drive under windows having only access to ssh. I can suggest you to use WinSCP that allows you to transfer file through ssh and it's free.

EDIT: well, sorry. Vinko posted before me and now i've learned a new thing :)

You could do it with jsoup http://jsoup.org/

Whitelist whitelist = Whitelist.none();
String cleanStr = Jsoup.clean(yourText, whitelist);

Incase of arrays, the base address (i.e. address of the array) is the address of the 1st element in the array. Also the array name acts as a pointer.

Consider a row of houses (each is an element in the array). To identify the row, you only need the 1st house address.You know each house is followed by the next (sequential).Getting the address of the 1st house, will also give you the address of the row.

Incase of string literals(character arrays defined at declaration), they are automatically appended by \0.

printf prints using the format specifier and the address provided. Since, you use %s it prints from the 1st address (incrementing the pointer using arithmetic) until '\0'

round(5.59, 1) is working fine. The problem is that 5.6 cannot be represented exactly in binary floating point.

>>> 5.6
5.5999999999999996
>>> 

As Vinko says, you can use string formatting to do rounding for display.

Python has a module for decimal arithmetic if you need that.

You can use the "extract" or "date_part" functions on intervals as well as timestamps, but I don't think that does what you want. For example, it gives 3 for an interval of '2 days, 3 hours'. However, you can convert an interval to a number of seconds by specifying 'epoch' as the time element you want: extract(epoch from '2 days, 3 hours'::interval) returns 183600 (which you then divide by 3600 to convert seconds to hours).

So, putting this all together, you get basically Michael's answer: extract(epoch from timestamp1 - timestamp2)/3600. Since you don't seem to care about which timestamp precedes which, you probably want to wrap that in abs:

SELECT abs(extract(epoch from timestamp1 - timestamp2)/3600)

I'm using a popup to show the map in a new window. I'm using the following url

https://www.google.com/maps?z=15&daddr=LATITUDE,LONGITUDE

HTML snippet

<a target='_blank' href='https://www.google.com/maps?z=15&daddr=${location.latitude},${location.longitude}'>Calculate route</a>

Here is my take on it, seems like most peoples solutions don't check if the item exists and it removes random values if it does not exist.

First check if the element exists by looking for it's index. If it does exist, remove it by its index using the splice method

elementPosition = array.indexOf(value);

if(elementPosition != -1) {
  array.splice(elementPosition, 1);
}

You can pass --force-recreate to docker compose up, which should use fresh containers.

I think the reasoning behind reusing containers is to preserve any changes during development. Note that Compose does something similar with volumes, which will also persist between container recreation (a recreated container will attach to its predecessor's volumes). This can be helpful, for example, if you have a Redis container used as a cache and you don't want to lose the cache each time you make a small change. At other times it's just confusing.

I don't believe there is any way you can force this from the Compose file.

Arguably it does clash with immutable infrastructure principles. The counter-argument is probably that you don't use Compose in production (yet). Also, I'm not sure I agree that immutable infra is the basic idea of Docker, although it's certainly a good use case/selling point.

The basis logic for such behavior is that Generics follow a mechanism of type erasure. So at run time you have no way if identifying the type of collection unlike arrays where there is no such erasure process. So coming back to your question...

So suppose there is a method as given below:

add(List<Animal>){
    //You can add List<Dog or List<Cat> and this will compile as per rules of polymorphism
}

Now if java allows caller to add List of type Animal to this method then you might add wrong thing into collection and at run time too it will run due to type erasure. While in case of arrays you will get a run time exception for such scenarios...

Thus in essence this behavior is implemented so that one cannot add wrong thing into collection. Now I believe type erasure exists so as to give compatibility with legacy java without generics....

That's because you are dealing with floating point numbers. Division by zero returns Infinity, which is similar to NaN (not a number).

If you want to prevent this, you have to test tab[i] before using it. Then you can throw your own exception, if you really need it.

You can find answer in depth here.

But in general with float you need to be aware and take care of the surrounding elements and inline-block simple way to line elements.

Thanks

I got the same error but I have fixed it by changing the file reading path from "ConfigFile.xml" to AppDomain.CurrentDomain.BaseDirectory.ToString() + "ConfigFile.xml"

In my case, this error due to file path error because task manager starts program from "System32" as initial path but the folder we thought.

You are trying to run bash, an interactive shell that requires a tty in order to operate. It doesn't really make sense to run this in "detached" mode with -d, but you can do this by adding -it to the command line, which ensures that the container has a valid tty associated with it and that stdin remains connected:

docker run -it -d -p 52022:22 basickarl/docker-git-test

You would more commonly run some sort of long-lived non-interactive process (like sshd, or a web server, or a database server, or a process manager like systemd or supervisor) when starting detached containers.

If you are trying to run a service like sshd, you cannot simply run service ssh start. This will -- depending on the distribution you're running inside your container -- do one of two things:

• It will try to contact a process manager like systemd or upstart to start the service. Because there is no service manager running, this will fail.

• It will actually start sshd, but it will be started in the background. This means that (a) the service sshd start command exits, which means that (b) Docker considers your container to have failed, so it cleans everything up.

If you want to run just ssh in a container, consider an example like this.

If you want to run sshd and other processes inside the container, you will need to investigate some sort of process supervisor.

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.

It don't create normally; you need to add it by yourself.

After adding Global.asax by

• Right clicking your website -> Add New Item -> Global Application Class -> Add

You need to add a class

• Right clicking App_Code -> Add New Item -> Class -> name it Global.cs -> Add

Inherit the newly generated by System.Web.HttpApplication and copy all the method created Global.asax to Global.cs and also add an inherit attribute to the Global.asax file.

Your Global.asax will look like this: -

<%@ Application Language="C#" Inherits="Global" %>

Your Global.cs in App_Code will look like this: -

public class Global : System.Web.HttpApplication
{
    public Global()
    {
        //
        // TODO: Add constructor logic here
        //
    }

    void Application_Start(object sender, EventArgs e)
    {
        // Code that runs on application startup

    }
    /// Many other events like begin request...e.t.c, e.t.c
}

Maybe it helps someone, but I had the same issue and it was due to a lack of storage space caused by a log getting way too big.

Hope it helps someone! :)

Just git rm subdir will be ok. that will remove the subdir as an index.

As others have answered… div is a “block element” (now redefined as Flow Content) and span is an “inline element” (Phrasing Content). Yes, you may change the default presentation of these elements, but there is a difference between “flow” versus “block”, and “phrasing” versus “inline”.

An element classified as flow content can only be used where flow content is expected, and an element classified as phrasing content can be used where phrasing content is expected. Since all phrasing content is flow content, a phrasing element can also be used anywhere flow content is expected. The specs provide more detailed info.

All phrasing elements, such as strong and em, can only contain other phrasing elements: you can’t put a table inside a cite for instance. Most flow content such as div and li can contain all types of flow content (as well as phrasing content), but there are a few exceptions: p, pre, and th are examples of non-phrasing flow content (“block elements”) that can only contain phrasing content (“inline elements”). And of course there are the normal element restrictions such as dl and table only being allowed to contain certain elements.

While both div and p are non-phrasing flow content, the div can contain other flow content children (including more divs and ps). On the other hand, p may only contain phrasing content children. That means you can’t put a div inside a p, even though both are non-phrasing flow elements.

Now here’s the kicker. These semantic specifications are unrelated to how the element is displayed. Thus, if you have a div inside a span, you will get a validation error even if you have span {display: block;} and div {display: inline;} in your CSS.

Here you go:

date +%Y%m%d%H%M%S

As man date says near the top, you can use the date command like this:

date [OPTION]... [+FORMAT]

That is, you can give it a format parameter, starting with a +. You can probably guess the meaning of the formatting symbols I used:

• %Y is for year
• %m is for month
• %d is for day
• ... and so on

You can find this, and other formatting symbols in man date.

For xCode 10, first you need to add the image in your assetsCatalogue and then type this:

let imageView = UIImageView(image: #imageLiteral(resourceName: "type the name of your image here..."))

For beginners, let imageView is the name of the UIImageView object we are about to create.

An example for embedding an image into a viewControler file would look like this:

import UIKit

class TutorialViewCotroller: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        let imageView = UIImageView(image: #imageLiteral(resourceName: "intoImage"))
        view.addSubview(imageView)
    }
}

Please notice that I did not use any extension for the image file name, as in my case it is a group of images.

From the SQL Server Management Studio you can right click on your database and select:

Tasks -> Generate Scripts

Then simply proceed through the wizard. Make sure to set 'Script Data' to TRUE when prompted to choose the script options.

This may have changed since the question was asked, but there is a difference between stopping an instance and terminating an instance.

If your instance is EBS-based, it can be stopped. It will remain in your account, but you will not be charged for it (you will continue to be charged for EBS storage associated with the instance and unused Elastic IP addresses). You can re-start the instance at any time.

If the instance is terminated, it will be deleted from your account. You’ll be charged for any remaining EBS volumes, but by default the associated EBS volume will be deleted. This can be configured when you create the instance using the command-line EC2 API Tools.

Here's what I came up with, and it's working for me. I added the following method(s) to my controller base class. (You can always make these static methods somewhere else that accept a controller as a parameter I suppose)

MVC2 .ascx style

protected string RenderViewToString<T>(string viewPath, T model) {
  ViewData.Model = model;
  using (var writer = new StringWriter()) {
    var view = new WebFormView(ControllerContext, viewPath);
    var vdd = new ViewDataDictionary<T>(model);
    var viewCxt = new ViewContext(ControllerContext, view, vdd,
                                new TempDataDictionary(), writer);
    viewCxt.View.Render(viewCxt, writer);
    return writer.ToString();
  }
}

Razor .cshtml style

public string RenderRazorViewToString(string viewName, object model)
{
  ViewData.Model = model;
  using (var sw = new StringWriter())
  {
    var viewResult = ViewEngines.Engines.FindPartialView(ControllerContext,
                                                             viewName);
    var viewContext = new ViewContext(ControllerContext, viewResult.View,
                                 ViewData, TempData, sw);
    viewResult.View.Render(viewContext, sw);
    viewResult.ViewEngine.ReleaseView(ControllerContext, viewResult.View);
    return sw.GetStringBuilder().ToString();
  }
}

Edit: added Razor code.

Let's say for instance you want to get a list of all your customers:

var customers = context.Customers.ToList();

And let's assume that each Customer object has a reference to its set of Orders, and that each Order has references to LineItems which may also reference a Product.

As you can see, selecting a top-level object with many related entities could result in a query that needs to pull in data from many sources. As a performance measure, Include() allows you to indicate which related entities should be read from the database as part of the same query.

Using the same example, this might bring in all of the related order headers, but none of the other records:

var customersWithOrderDetail = context.Customers.Include("Orders").ToList();

As a final point since you asked for SQL, the first statement without Include() could generate a simple statement:

SELECT * FROM Customers;

The final statement which calls Include("Orders") may look like this:

SELECT *
FROM Customers JOIN Orders ON Customers.Id = Orders.CustomerId;

× × or × (same thing) U+00D7 multiplication sign

× same character with a strong font weight

? ⨯ U+2A2F Gibbs product

? ✖ U+2716 heavy multiplication sign

There's also an emoji ❌ if you support it. If you don't you just saw a square = ❌

I also made this simple code example on Codepen when I was working with a designer who asked me to show her what it would look like when I asked if I could replace your close button with a coded version rather than an image.

To do this:

1. open terminal

2. type in the terminal: nano ; which is a text editor available for the terminal. when you do this. something like this would appear.

3. here you can type in your C program

4. type in control(^) + x -> which means to exit.

5. save the file by typing in y to save the file

6. write the file name; e.g. helloStack.c (don't forget to add .c)

7. when this appears, type in gcc helloStack.c

8. then ./a.out: this should give you your result!!

You probably need to open a command prompt with the PATH set up properly. Look for an icon in the start menu that says something like "Visual C++ 2005 Command Prompt". You should be able to run dumpbin (and all the other command line tools) from there.

Here is how we fixed this.

Step 1: Open Keychain access, delete "Apple world wide Developer relations certification authority" (which expires on 14th Feb 2016) from both "Login" and "System" sections. If you can't find it, use “Show Expired Certificates” in the View menu.

Step 2: Download this and add it to Keychain access -> Certificates (which expires on 8th Feb 2023).

Step 3: Everything should be back to normal and working now.

1. uninstall node completely with the commands

curl -ksO https://gist.githubusercontent.com/nicerobot/2697848/raw/uninstall-node.sh
chmod +x ./uninstall-node.sh
./uninstall-node.sh
rm uninstall-node.sh

Or you could check out this website: How do I completely uninstall Node.js, and reinstall from beginning (Mac OS X)

if this doesn't work, you need to remove node via control panel or any other method. As long as it gets removed.

2. Install node via this website: https://nodejs.org/en/download/

If you use nvm, you can use:

nvm install node

You can already check if it works, then you don't need to take the following steps with: npm -v and then node -v

if you have nvm installed: command -v nvm

3. Uninstall npm using the following command:

sudo npm uninstall npm -g

Or, if that fails, get the npm source code, and do:

sudo make uninstall

If you have nvm installed, then use: nvm uninstall npm

4. Install npm using the following command: npm install -g grunt

You can describe your css selection like cascading style sheet dows:

In Java, an int is 32 bits. A byte is 8 bits .

Most primitive types in Java are signed, and byte, short, int, and long are encoded in two's complement. (The char type is unsigned, and the concept of a sign is not applicable to boolean.)

In this number scheme the most significant bit specifies the sign of the number. If more bits are needed, the most significant bit ("MSB") is simply copied to the new MSB.

So if you have byte 255: 11111111 and you want to represent it as an int (32 bits) you simply copy the 1 to the left 24 times.

Now, one way to read a negative two's complement number is to start with the least significant bit, move left until you find the first 1, then invert every bit afterwards. The resulting number is the positive version of that number

For example: 11111111 goes to 00000001 = -1. This is what Java will display as the value.

What you probably want to do is know the unsigned value of the byte.

You can accomplish this with a bitmask that deletes everything but the least significant 8 bits. (0xff)

So:

byte signedByte = -1;
int unsignedByte = signedByte & (0xff);

System.out.println("Signed: " + signedByte + " Unsigned: " + unsignedByte);

Would print out: "Signed: -1 Unsigned: 255"

What's actually happening here?

We are using bitwise AND to mask all of the extraneous sign bits (the 1's to the left of the least significant 8 bits.) When an int is converted into a byte, Java chops-off the left-most 24 bits

1111111111111111111111111010101
&
0000000000000000000000001111111
=
0000000000000000000000001010101

Since the 32nd bit is now the sign bit instead of the 8th bit (and we set the sign bit to 0 which is positive), the original 8 bits from the byte are read by Java as a positive value.

You do not have to have the RETURN stament.

Ben Alman has a great jQuery plugin for dealing with this: http://benalman.com/projects/jquery-hashchange-plugin/

If you're not using jQuery it may be an interesting reference to dissect.

you may put your Auth settings into a Environment. Like:

SetEnvIf HTTP_HOST testsite.local APPLICATION_ENV=development
<IfDefine !APPLICATION_ENV>
  Allow from all
  AuthType Basic
  AuthName "My Testseite - Login" 
  AuthUserFile /Users/tho/htdocs/wgh_staging/.htpasswd
  Require user username
</IfDefine>

The Auth is working, but I couldn't get my environment really running.

For the question

How can i run a jar file in command prompt but with arguments

.

To pass arguments to the jar file at the time of execution

java -jar myjar.jar arg1 arg2

In the main() method of "Main-Class" [mentioned in the manifest.mft file]of your JAR file. you can retrieve them like this:

String arg1 = args[0];
String arg2 = args[1];

I found this today. It really helped me. http://www.propra.nl/playground/css_filters/

All you need is to add this to your css style.:

div {-webkit-filter: brightness(57%)}

Jlordo approach covers specific situation. If you try to build an abstract method out of it, you can face a difficulty to check if 'textFrom' is before 'textTo'. Otherwise method can return a match for some other occurance of 'textFrom' in text.

Here is a ready-to-go abstract method that covers this disadvantage:

  /**
   * Get text between two strings. Passed limiting strings are not 
   * included into result.
   *
   * @param text     Text to search in.
   * @param textFrom Text to start cutting from (exclusive).
   * @param textTo   Text to stop cuutting at (exclusive).
   */
  public static String getBetweenStrings(
    String text,
    String textFrom,
    String textTo) {

    String result = "";

    // Cut the beginning of the text to not occasionally meet a      
    // 'textTo' value in it:
    result =
      text.substring(
        text.indexOf(textFrom) + textFrom.length(),
        text.length());

    // Cut the excessive ending of the text:
    result =
      result.substring(
        0,
        result.indexOf(textTo));

    return result;
  }

If you're getting source in Content Use the following method

try
{
    var response = restClient.Execute<List<EmpModel>>(restRequest);

    var jsonContent = response.Content;

    var data = JsonConvert.DeserializeObject<List<EmpModel>>(jsonContent);

    foreach (EmpModel item in data)
    {
        listPassingData?.Add(item);
    }
}
catch (Exception ex)
{
    Console.WriteLine($"Data get mathod problem {ex} ");
}

conn = sqlite3.connect('/path/to/your/sqlite_file.db')
c = conn.cursor()
for item in my_list:
  c.execute('insert into tablename values (?,?,?)', item)

Question is about merging two images, however in this specified case you shouldn't do that. You should put Content Image (ie. cover) into <img /> tag, and Style Image into CSS, why?

1. As I said the cover belongs to the content of the document, while that vinyl record and shadow are just a part of the page styles.
2. Such separation is much more convenient to use. User can easily copy that image. It's easier to index by web-spiders.
3. Finally, it's much easier to maintain.

So use a very simple code:

<div class="cover">
   <img src="/content/images/covers/movin-mountains.png" alt="Moving mountains by Pneuma" width="100" height="100" />
</div>

.cover {
    padding: 10px;
    padding-right: 100px;

    background: url(/style/images/cover-background.png) no-repeat;
}

Instance of a class when compared with == comes to non-equal. The best way is to ass the cmp function to your class which will do the stuff.

If you want to do comparison by the content you can simply use cmp(obj1,obj2)

In your case cmp(doc1,doc2) It will return -1 if the content wise they are same.

Example:

<input 
  type="submit" 
  onclick="this.form.action='new_target.php?do=alternative_submit'" 
  value="Alternative Save"
/>

Voila. Very "fancy", three word JavaScript!

All other answers sounds good, I would like to cover my case, where I had to make an animated LaunchScreen, then after 3 to 4 seconds of animation the next task was to move to Home screen. I tried segues, but that created problem for destination view. So at the end I accessed AppDelegates's Window property and I assigned a new NavigationController screen to it,

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let appDelegate = UIApplication.shared.delegate as! AppDelegate
let homeVC = storyboard.instantiateViewController(withIdentifier: "HomePageViewController") as! HomePageViewController

//Below's navigationController is useful if u want NavigationController in the destination View
let navigationController = UINavigationController(rootViewController: homeVC)
appDelegate.window!.rootViewController = navigationController

If incase, u don't want navigationController in the destination view then just assign as,

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let appDelegate = UIApplication.shared.delegate as! AppDelegate
let homeVC = storyboard.instantiateViewController(withIdentifier: "HomePageViewController") as! HomePageViewController
appDelegate.window!.rootViewController = homeVC

You cannot manually expire a token after it has been created. Thus, you cannot log out with JWT on the server-side as you do with sessions.

JWT is stateless, meaning that you should store everything you need in the payload and skip performing a DB query on every request. But if you plan to have a strict log out functionality, that cannot wait for the token auto-expiration, even though you have cleaned the token from the client-side, then you might need to neglect the stateless logic and do some queries. so what's a solution?

• Set a reasonable expiration time on tokens

• Delete the stored token from client-side upon log out

• Query provided token against The Blacklist on every authorized request

Blacklist

“Blacklist” of all the tokens that are valid no more and have not expired yet. You can use a DB that has a TTL option on documents which would be set to the amount of time left until the token is expired.

Redis

Redis is a good option for blacklist, which will allow fast in-memory access to the list. Then, in the middleware of some kind that runs on every authorized request, you should check if the provided token is in The Blacklist. If it is you should throw an unauthorized error. And if it is not, let it go and the JWT verification will handle it and identify if it is expired or still active.

For more information, see How to log out when using JWT. by Arpy Vanyan

Python 3.9 adds the zoneinfo module so now it can be done as follows (stdlib only):

from zoneinfo import ZoneInfo
from datetime import datetime

utc_unaware = datetime(2020, 10, 31, 12)  # loaded from database
utc_aware = utc_unaware.replace(tzinfo=ZoneInfo('UTC'))  # make aware
local_aware = utc_aware.astimezone(ZoneInfo('localtime'))  # convert

Central Europe is 1 or 2 hours ahead of UTC, so local_aware is:

datetime.datetime(2020, 10, 31, 13, 0, tzinfo=backports.zoneinfo.ZoneInfo(key='localtime'))

as str:

2020-10-31 13:00:00+01:00

Windows has no system time zone database, so here an extra package is needed:

pip install tzdata  

There is a backport to allow use in Python 3.6 to 3.8:

sudo pip install backports.zoneinfo

Then:

from backports.zoneinfo import ZoneInfo

I use a mixture of float and overflow-x:hidden. Minimal code, always works.

https://jsfiddle.net/9934sc4d/4/ - PLUS you don't need to clear your float!

.left-half{
    width:200px;
    float:left;
}
.right-half{
    overflow-x:hidden;
}

Using SSMS, I made sure the user had connect permissions on both the database and ReportServer.

On the specific database being queried, under properties, I mapped their credentials and enabled datareader and public permissions. Also, as others have stated-I made sure there were no denyread/denywrite boxes selected.

I did not want to enable db ownership when for their reports since they only needed to have select permissions.

It happened the same to me after updating Xcode. I tried everything I can do such as reinstalling cocoapods and cleaning the project, but it didn't work. Now it's been solved after restart the system.

find . -type f -print0 | xargs -0 <sed/perl/ruby cmd> will process multiple space contained file names at once loading one interpreter per batch. Much faster.

You can do a simple download of the directory tree:

git archive --remote [email protected]:foobar/Test.git HEAD:foo | tar xf -

But if you mean to check it out, and be able to do commits and push them back, no you can't do that.

Use the basename command:

basename /home/user/new/*.txt

It's really simple to fix the issue, however keep in mind that you should fork and commit your changes for each library you are using in their repositories to help others as well.

Let's say you have something like this in your code:

$str = "test";
echo($str{0});

since PHP 7.4 curly braces method to get individual characters inside a string has been deprecated, so change the above syntax into this:

$str = "test";
echo($str[0]);

Fixing the code in the question will look something like this:

public function getRecordID(string $zoneID, string $type = '', string $name = ''): string
{
    $records = $this->listRecords($zoneID, $type, $name);
    if (isset($records->result[0]->id)) {
        return $records->result[0]->id;
    }
    return false;
}

Just a wild guess: (not much to go on) but I have had similar problems when, for example, I was using the IIS rewrite module on my local machine (and it worked fine), but when I uploaded to a host that did not have that add-on module installed, I would get a 500 error with very little to go on - sounds similar. It drove me crazy trying to find it.

So make sure whatever options/addons that you might have and be using locally in IIS are also installed on the host.

Similarly, make sure you understand everything that is being referenced/used in your web.config - that is likely the problem area.

If your variable is the percentage:

var myWidth = 70;
$('div#somediv').width(myWidth + '%');

If your variable is in pixels, and you want the percentage it take up of the parent:

var myWidth = 140;
var myPercentage = (myWidth / $('div#somediv').parent().width()) * 100;
$('div#somediv').width(myPercentage + '%');

I found a way to convert the response.result.value (inside an Alamofire responseJSON closure) into JSON format that I use in my app.

I'm using Alamofire 3 and Swift 2.2.

Here's the code I used:

    Alamofire.request(.POST, requestString,
                      parameters: parameters,
                      encoding: .JSON,
                      headers: headers).validate(statusCode: 200..<303)
                                       .validate(contentType: ["application/json"])
                                       .responseJSON { (response) in
        NSLog("response = \(response)")

        switch response.result {
        case .Success:
            guard let resultValue = response.result.value else {
                NSLog("Result value in response is nil")
                completionHandler(response: nil)
                return
            }

            let responseJSON = JSON(resultValue)

            // I do any processing this function needs to do with the JSON here

            // Here I call a completionHandler I wrote for the success case
        break
        case .Failure(let error):
            NSLog("Error result: \(error)")
            // Here I call a completionHandler I wrote for the failure case
            return
        }

Just for completeness, the following is a Java solution. I am certain the same could be done in C# as well. It avoids having to specify the type anywhere in code - instead, you specify it in the strings you are trying to parse.

The problem is that there isn't any way to know which enumeration the String might match - so the answer is to solve that problem.

Instead of accepting just the string value, accept a String that has both the enumeration and the value in the form "enumeration.value". Working code is below - requires Java 1.8 or later. This would also make the XML more precise as in you would see something like color="Color.red" instead of just color="red".

You would call the acceptEnumeratedValue() method with a string containing the enum name dot value name.

The method returns the formal enumerated value.

import java.util.HashMap;
import java.util.Map;
import java.util.function.Function;


public class EnumFromString {

    enum NumberEnum {One, Two, Three};
    enum LetterEnum {A, B, C};


    Map<String, Function<String, ? extends Enum>> enumsByName = new HashMap<>();

    public static void main(String[] args) {
        EnumFromString efs = new EnumFromString();

        System.out.print("\nFirst string is NumberEnum.Two - enum is " + efs.acceptEnumeratedValue("NumberEnum.Two").name());
        System.out.print("\nSecond string is LetterEnum.B - enum is " + efs.acceptEnumeratedValue("LetterEnum.B").name());

    }

    public EnumFromString() {
        enumsByName.put("NumberEnum", s -> {return NumberEnum.valueOf(s);});
        enumsByName.put("LetterEnum", s -> {return LetterEnum.valueOf(s);});
    }

    public Enum acceptEnumeratedValue(String enumDotValue) {

        int pos = enumDotValue.indexOf(".");

        String enumName = enumDotValue.substring(0, pos);
        String value = enumDotValue.substring(pos + 1);

        Enum enumeratedValue = enumsByName.get(enumName).apply(value);

        return enumeratedValue;
    }


}

In the current version (v0.5.0-pre) the port seems to be available as a property on the server object, see http://nodejs.org/docs/v0.4.7/api/net.html#server.address

server.listen(8088);
console.log(server.address());
console.log(server.address().address);
console.log(server.address().port);

outputs

There is a way to cleanup workspace in Jenkins. You can clean up the workspace before build or after build.

First, install Workspace Cleanup Plugin.

To clean up the workspace before build: Under Build Environment, check the box that says Delete workspace before build starts.

To clean up the workspace after the build: Under the heading Post-build Actions select Delete workspace when build is done from the Add Post-build Actions drop down menu.

I recently faced this problem after I installed android emulator using the sdk manager of android studio - which also upgraded my android sdk tools to 26.0.1 (as it was a prerequisite - according to the sdk manager of android studio).

In my case, I simply replaced the tools folder of android sdk with tools folder from an older android sdk. This downgraded the android sdk tools, but now I can open the sdk manager using SDK Manager.exe.

Seems like an old question but still relevant.

I think it is a blocked update issue.

The main problem is the new URL (route) is supposed to be rendered by the same component(Costumers) as you are currently in (current URL).

So solution is rather simple, make the window url as a prop, so react has a chance to detect the prop change (therefore the url change), and act accordingly.

A nice usecase described in the official react blog called Recommendation: Fully uncontrolled component with a key.

So the solution is to change from render() { return( <ul>

to render() { return( <ul key={this.props.location.pathname}>

So whenever the location changed by react-router, the component got scrapped (by react) and a new one gets initiated with the right values (by react).

Oh, and pass the location as prop to the component(Costumers) where the redirect will happen if it is not passed already.

Hope it helps someone.

Without find:

for f in /tmp/* tmp/**/* ; do
  ...
done;

/tmp/* are files in dir and /tmp/**/* are files in subfolders. It is possible that you have to enable globstar option (shopt -s globstar). So for the question the code should look like this:

shopt -s globstar
for f in /tmp/*.pdf /tmp/*.doc tmp/**/*.pdf tmp/**/*.doc ; do
  rm "$f"
done

Note that this requires bash =4.0 (or zsh without shopt -s globstar, or ksh with set -o globstar instead of shopt -s globstar). Furthermore, in bash <4.3, this traverses symbolic links to directories as well as directories, which is usually not desirable.

There's an ELSE in the DOS batch language? Back in the days when I did more of this kinda thing, there wasn't.

If my theory is correct and your ELSE is being ignored, you may be better off doing

IF NOT EXIST file GOTO label

...which will also save you a line of code (the one right after your IF).

Second, I vaguely remember some kind of bug with testing for the existence of directories. Life would be easier if you could test for the existence of a file in that directory. If there's no file you can be sure of, something to try (this used to work up to Win95, IIRC) would be to append the device file name NUL to your directory name, e.g.

IF NOT EXIST C:\dir\NUL GOTO ...

length and dbms_lob.getlength return the number of characters when applied to a CLOB (Character LOB). When applied to a BLOB (Binary LOB), dbms_lob.getlength will return the number of bytes, which may differ from the number of characters in a multi-byte character set.

As the documentation doesn't specify what happens when you apply length on a BLOB, I would advise against using it in that case. If you want the number of bytes in a BLOB, use dbms_lob.getlength.

After some years have passed, you can do that now with ES6 Array.from (or spread syntax):

const navbar = Array.from(document.querySelectorAll('#navbar>ul>li'));_x000D_
console.log('Get first: ', navbar[0].textContent);_x000D_
_x000D_
// If you need to iterate once over all these nodes, you can use the callback function:_x000D_
console.log('Iterate with Array.from callback argument:');_x000D_
Array.from(document.querySelectorAll('#navbar>ul>li'),li => console.log(li.textContent))_x000D_
_x000D_
// ... or a for...of loop:_x000D_
console.log('Iterate with for...of:');_x000D_
for (const li of document.querySelectorAll('#navbar>ul>li')) {_x000D_
    console.log(li.textContent);_x000D_
}

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

<div id="navbar">_x000D_

An easy way to get this is:

function getPathFromUrl(url) {
  return url.split("?")[0];
}

For those who also wish to remove the hash (not part of the original question) when no querystring exists, that requires a little bit more:

function stripQueryStringAndHashFromPath(url) {
  return url.split("?")[0].split("#")[0];
}

EDIT

@caub (originally @crl) suggested a simpler combo that works for both query string and hash (though it uses RegExp, in case anyone has a problem with that):

function getPathFromUrl(url) {
  return url.split(/[?#]/)[0];
}

From R..'s answer:

However, this is probably a very bad idea, because the resulting type is an array type, but users of it won't see that it's an array type. If used as a function argument, it will be passed by reference, not by value, and the sizeof for it will then be wrong.

Users who don't see that it's an array will most likely write something like this (which fails):

#include <stdio.h>

typedef int twoInts[2];

void print(twoInts *twoIntsPtr);
void intermediate (twoInts twoIntsAppearsByValue);

int main () {
    twoInts a;
    a[0] = 0;
    a[1] = 1;
    print(&a);
    intermediate(a);
    return 0;
}
void intermediate(twoInts b) {
    print(&b);
}

void print(twoInts *c){
    printf("%d\n%d\n", (*c)[0], (*c)[1]);
}

It will compile with the following warnings:

In function ‘intermediate’:
warning: passing argument 1 of ‘print’ from incompatible pointer type [enabled by default]
    print(&b);
     ^
note: expected ‘int (*)[2]’ but argument is of type ‘int **’
    void print(twoInts *twoIntsPtr);
         ^

And produces the following output:

0
1
-453308976
32767

Try this query.. It uses the Analytic function SUM:

SELECT * FROM
(  
 SELECT SUM(1) OVER(PARTITION BY ctn_no) cnt, A.*
 FROM table1 a 
 WHERE s_ind ='Y'   
)
WHERE cnt > 2

Am not sure why you are identifying a record as a duplicate if the ctn_no repeats more than 2 times. FOr me it repeats more than once it is a duplicate. In this case change the las part of the query to WHERE cnt > 1

The best precision you can possibly get is through the use of the x86-only "rdtsc" instruction, which can provide clock-level resolution (ne must of course take into account the cost of the rdtsc call itself, which can be measured easily on application startup).

The main catch here is measuring the number of clocks per second, which shouldn't be too hard.

Just check my scripts it's working well:

  function handleFileSelect(evt) {
    var files = evt.target.files; // FileList object

    // Loop through the FileList and render image files as thumbnails.
    for (var i = 0, f; f = files[i]; i++) {

      // Only process image files.
      if (!f.type.match('image.*')) {
        continue;
      }

      var reader = new FileReader();

      // Closure to capture the file information.
      reader.onload = (function(theFile) {
        return function(e) {
          // Render thumbnail.
          var span = document.createElement('span');
          span.innerHTML = ['<img class="thumb" src="', e.target.result,
                            '" title="', escape(theFile.name), '"/>'].join('');
          document.getElementById('list').insertBefore(span, null);
        };
      })(f);

      // Read in the image file as a data URL.
      reader.readAsDataURL(f);
    }
  }

  document.getElementById('files').addEventListener('change', handleFileSelect, false);

#list img{
  width: auto;
  height: 100px;
  margin: 10px ;
}

with for-loop:

std::ifstream myFile;
std::string line;
int lines;

myFile.open(path);

for(lines = 0; std::getline(myFile,line); lines++);

std::cout << lines << std::endl;

First thing first. set the column in which you are working in by clicking on format cells->number-> date and then format e.g Jan-16 representing Jan, 1, 2016. and then apply either of the formulas above.

TRY this out it works fine ...

<!DOCTYPE html>
<html>
<body>

<input type="button"  onclick="openWin()" value="open"/>
<input type="button"  onclick="closeWin()" value="close"/>

<script>
var myWindow;

function openWin()
{
myWindow = window.open("","myWindow","width=200,height=100");
myWindow.document.write("<p>This is 'myWindow'</p>");
}

function closeWin()
{
myWindow.close();
}
</script>

</body>
</html>

this works as you want it to work

Using width/height on inline elements is not always a good idea. You can use display: inline-block instead

Usually two arrays will have some small numeric errors,

You can use numpy.allclose(A,B), instead of (A==B).all(). This returns a bool True/False

I did the following to solve the mentioned problem. I got the mentioned problem when I was trying to run the built exe, even I successfully built the exe using pyinstaller. I did this on Windows 10.

1. go to https://pypi.org/project/six/#files
2. download "six-1.14.0.tar.gz (33.9 kB)"
3. unzip it, copy and paste "six.py" into your source directory.
4. import "six" module into your source code (import six)
5. run source script.

In Oracle, to insert multiple rows into table t with columns col1, col2 and col3 you can use the following syntax:

INSERT ALL
   INTO t (col1, col2, col3) VALUES ('val1_1', 'val1_2', 'val1_3')
   INTO t (col1, col2, col3) VALUES ('val2_1', 'val2_2', 'val2_3')
   INTO t (col1, col2, col3) VALUES ('val3_1', 'val3_2', 'val3_3')
   .
   .
   .
SELECT 1 FROM DUAL;

I use android:layout_centerInParent="true" and it worked

1. First of all, there is no difference between View.OnClickListener and OnClickListener. If you just use View.OnClickListener directly, then you don't need to write-

   import android.view.View.OnClickListener

2. You set an OnClickListener instance (e.g. myListener named object)as the listener to a view via setOnclickListener(). When a click event is fired, that myListener gets notified and it's onClick(View view) method is called. Thats where we do our own task. Hope this helps you.

I wrote the Text-IO library, which can deal with the problem of System.console() being null when running an application from within an IDE.

It introduces an abstraction layer similar to the one proposed by McDowell. If System.console() returns null, the library switches to a Swing-based console.

In addition, Text-IO has a series of useful features:

• supports reading values with various data types.
• allows masking the input when reading sensitive data.
• allows selecting a value from a list.
• allows specifying constraints on the input values (format patterns, value ranges, length constraints etc.).

Usage example:

TextIO textIO = TextIoFactory.getTextIO();

String user = textIO.newStringInputReader()
        .withDefaultValue("admin")
        .read("Username");

String password = textIO.newStringInputReader()
        .withMinLength(6)
        .withInputMasking(true)
        .read("Password");

int age = textIO.newIntInputReader()
        .withMinVal(13)
        .read("Age");

Month month = textIO.newEnumInputReader(Month.class)
        .read("What month were you born in?");

textIO.getTextTerminal().println("User " + user + " is " + age + " years old, " +
        "was born in " + month + " and has the password " + password + ".");

In this image you can see the above code running in a Swing-based console.

With a simple JSON object, you don't need jQuery:

for (var i in json) {
   for (var j in json[i]) {
     console.log(json[i][j]);
   }
}

You can redirect the regular stdin through unit 3 to keep the get it inside the pipeline:

{ cat notify-finished | while read line; do
    read -u 3 input
    echo "$input"
done; } 3<&0

BTW, if you really are using cat this way, replace it with a redirect and things become even easier:

while read line; do
    read -u 3 input
    echo "$input"
done 3<&0 <notify-finished

Or, you can swap stdin and unit 3 in that version -- read the file with unit 3, and just leave stdin alone:

while read line <&3; do
    # read & use stdin normally inside the loop
    read input
    echo "$input"
done 3<notify-finished

You can try PHP protect which is a free PHP obfuscator to obfuscate your PHP code.
It is very nice, easy to use and also free. EDIT: This service is not live anymore.

As for what others have written here about not using obfuscation because it can be broken etc:
I have only one thing to answer them - don't lock your house door because anyone can pick your lock.
This is exactly the case, obfuscation is not meant to prevent 100% code theft. It only needs to make it a time-consuming task so it will be cheaper to pay the original coder. Hope this helps.

In Python, execution does NOT have to begin at main. The first line of "executable code" is executed first.

def main():
    print("main code")

def meth1():
    print("meth1")

meth1()
if __name__ == "__main__":main() ## with if

Output -

meth1
main code

More on main() - http://ibiblio.org/g2swap/byteofpython/read/module-name.html

A module's __name__

Every module has a name and statements in a module can find out the name of its module. This is especially handy in one particular situation - As mentioned previously, when a module is imported for the first time, the main block in that module is run. What if we want to run the block only if the program was used by itself and not when it was imported from another module? This can be achieved using the name attribute of the module.

Using a module's __name__

#!/usr/bin/python
# Filename: using_name.py

if __name__ == '__main__':
    print 'This program is being run by itself'
else:
    print 'I am being imported from another module'

Output -

$ python using_name.py
This program is being run by itself
$ python
>>> import using_name
I am being imported from another module
>>>

How It Works -

Every Python module has it's __name__ defined and if this is __main__, it implies that the module is being run standalone by the user and we can do corresponding appropriate actions.

In PostgreSQL 9.1, the idle connections with following query. It helped me to ward off the situation which warranted in restarting the database. This happens mostly with JDBC connections opened and not closed properly.

SELECT
   pg_terminate_backend(procpid)
FROM
   pg_stat_activity
WHERE
   current_query = '<IDLE>'
AND
   now() - query_start > '00:10:00';

Just a mention with jQuery v3.2.1 and Laravel 5.6.

Case 1: The JS object posted directly, like:

$.post("url", {name:'John'}, function( data ) {
});

Corresponding Laravel PHP code should be:

parse_str($request->getContent(),$data); //JSON will be parsed to object $data

Case 2: The JSON string posted, like:

$.post("url", JSON.stringify({name:'John'}), function( data ) {
});

Corresponding Laravel PHP code should be:

$data = json_decode($request->getContent(), true);

Maybe it's is completely possible with only CSS but I prefer to avoid "float" as much as I can because it interferes with it's parent's height.

If you are using jQuery, you can create a simple `wrapN` plugin that is similar to `wrapAll` except it only wraps "N" elements and then breaks and wraps the next "N" elements using a loop. Then set your wrappers class to `display: block;`.

(function ($) {
    $.fn.wrapN = function (wrapper, n, start) {
        if (wrapper === undefined || n === undefined) return false;
        if (start === undefined) start = 0;
        for (var i = start; i < $(this).size(); i += n)
           $(this).slice(i, i + n).wrapAll(wrapper);
        return this;
    };
}(jQuery));

$(document).ready(function () {
    $("li").wrapN("<span class='break' />", 3);
});

Here is a JSFiddle of the finished product:

http://jsfiddle.net/dustinpoissant/L79ahLoz/

following @tony's approach, changed the getTableHeight() function to

<div id="grid1" ui-grid="$ctrl.gridOptions" class="grid" ui-grid-auto-resize style="{{$ctrl.getTableHeight()}}"></div>

getTableHeight() {
    var offsetValue = 365;
    return "height: " + parseInt(window.innerHeight - offsetValue ) + "px!important";
}

the grid would have a dynamic height with regards to window height as well.

If all else fails, copy the local.properties file to the root of the project directory. Simply.

server_name supports suffix matches using .mydomain.com syntax:

server {
  server_name .mydomain.com;
  rewrite ^ http://www.adifferentdomain.com$request_uri? permanent;
}

or on any version 0.9.1 or higher:

server {
  server_name .mydomain.com;
  return 301 http://www.adifferentdomain.com$request_uri;
}

Add the following CSS:

For the parent div:

style="display: flex;"

For child div:

style="align-items: stretch;"

TimeSpan.FromTicks(DateTime.Now.Ticks)

subprocess.call will avoid problems with having to deal with quoting conventions of various shells. It accepts a list, rather than a string, so arguments are more easily delimited. i.e.

import subprocess
subprocess.call(['C:\\Temp\\a b c\\Notepad.exe', 'C:\\test.txt'])

Documented couple of design issues with this in a comment above. Short story, in Oracle, you need to limit the results manually when you have large tables and/or tables with same column names (and you don't want to explicit type them all out and rename them all). Easy solution is to figure out your breakpoint and limit that in your query. Or you could also do this in the inner query if you don't have the conflicting column names constraint. E.g.

WHERE m_api_log.created_date BETWEEN TO_DATE('10/23/2015 05:00', 'MM/DD/YYYY HH24:MI') 
                                 AND TO_DATE('10/30/2015 23:59', 'MM/DD/YYYY HH24:MI')  

will cut down the results substantially. Then you can ORDER BY or even do the outer query to limit rows.

Also, I think TOAD has a feature to limit rows; but, not sure that does limiting within the actual query on Oracle. Not sure.

To update a subset of fields, you can use update_fields:

survey.save(update_fields=["active"]) 

The update_fields argument was added in Django 1.5. In earlier versions, you could use the update() method instead:

Survey.objects.filter(pk=survey.pk).update(active=True)

In my case the IIS did not have the necessary permissions to access the relevant ASPX path.

I gave the IIS user permissions to the relevant directory and all was well.
