Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

Remove warnings.filterwarnings and add:

numpy.seterr(all='raise')

<code>
import cmath
import math
print(" we are going to programming second grade equation in python")
print(" a^2 x + b x + c =0")

num1 = int(input(" enter A please : "))
num2 = int(input(" enter B please : "))
num3 = int(input(" enter c please : "))
v = num2*num2 - 4 *num1 * num3
print(v)
if v < 0 :
    print("wrong values")
else:
    print("root of delta =", v)
    k= math.sqrt(v)

def two_sol(x,y) :
    x_f= (-y + v)/(4*x)
    x_s =(-y - v)/(4*x)
    return x_f , x_s

def one_sol(x):
    x_f = (-y + v) / (4 * x)

if v >0 :
    print("we have two solution :" ,two_sol(num1,num2)) 
elif v == 0:
    print( "we have one solution :" , one_sol(y)) 
else:
    print(" there is no solution !!")

I know that this question is a little old, but I thought that I would provide an alternative which, in my opinion, might be a little easier. If you're willing to add "temporary" columns to a data set, you can use Excel's Analysis ToolPak?Data Analysis?Regression. The secret to doing a quadratic or a cubic regression analysis is defining the Input X Range:.

If you're doing a simple linear regression, all you need are 2 columns, X & Y. If you're doing a quadratic, you'll need X_1, X_2, & Y where X_1 is the x variable and X_2 is x^2; likewise, if you're doing a cubic, you'll need X_1, X_2, X_3, & Y where X_1 is the x variable, X_2 is x^2 and X_3 is x^3. Notice how the Input X Range is from A1 to B22, spanning 2 columns.

The following image the output of the regression analysis. I've highlighted the common outputs, including the R-Squared values and all the coefficients.

When working with multiple people, it's sometimes difficult to know exactly what's happening. Using a format string instead of concatenation can avoid one particular annoyance that's happened a whole ton of times to us:

Say, a function requires an argument, and you write it expecting to get a string:

In [1]: def foo(zeta):
   ...:     print 'bar: ' + zeta

In [2]: foo('bang')
bar: bang

So, this function may be used pretty often throughout the code. Your coworkers may know exactly what it does, but not necessarily be fully up-to-speed on the internals, and may not know that the function expects a string. And so they may end up with this:

In [3]: foo(23)
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

/home/izkata/<ipython console> in <module>()

/home/izkata/<ipython console> in foo(zeta)

TypeError: cannot concatenate 'str' and 'int' objects

There would be no problem if you just used a format string:

In [1]: def foo(zeta):
   ...:     print 'bar: %s' % zeta
   ...:     
   ...:     

In [2]: foo('bang')
bar: bang

In [3]: foo(23)
bar: 23

The same is true for all types of objects that define __str__, which may be passed in as well:

In [1]: from datetime import date

In [2]: zeta = date(2012, 4, 15)

In [3]: print 'bar: ' + zeta
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

/home/izkata/<ipython console> in <module>()

TypeError: cannot concatenate 'str' and 'datetime.date' objects

In [4]: print 'bar: %s' % zeta
bar: 2012-04-15

So yes: If you can use a format string do it and take advantage of what Python has to offer.

I decide to add on, rather than posting my solution to another post. Below are the solution that I build, may not be perfect, but so far the output are good.

Important: it will pass through all the points!

If you have any idea, to make it better, please share to me. Thanks.

If you are looking for a intuition based answer I would like to put up two interpretations for you.

1. Imagine a very high hill with a very broad base as well. To reach the top of the hill there are two ways: one is a dedicated pathway going spirally around the hill reaching at the top, the other: small terrace like carvings cut out to provide a staircase. Now if the first way is reaching in linear time O(n), the second one is O(log n).

2. Imagine an algorithm, which accepts an integer, n as input and completes in time proportional to n then it is O(n) or theta(n) but if it runs in time proportion to the number of digits or the number of bits in the binary representation on number then the algorithm runs in O(log n) or theta(log n) time.

Strangely, the answers above removes the 'duplicates' but what if I want to remove the duplicated value also?? The following should be useful and does not create a new object in memory!

def dictRemoveDuplicates(self):
    a=[[1,'somevalue1'],[1,'somevalue2'],[2,'somevalue1'],[3,'somevalue4'],[5,'somevalue5'],[5,'somevalue1'],[5,'somevalue1'],[5,'somevalue8'],[6,'somevalue9'],[6,'somevalue0'],[6,'somevalue1'],[7,'somevalue7']]


print(a)
temp = 0
position = -1
for pageNo, item in a:
    position+=1
    if pageNo != temp:
        temp = pageNo
        continue
    else:
        a[position] = 0
        a[position - 1] = 0
a = [x for x in a if x != 0]         
print(a)

and the o/p is:

[[1, 'somevalue1'], [1, 'somevalue2'], [2, 'somevalue1'], [3, 'somevalue4'], [5, 'somevalue5'], [5, 'somevalue1'], [5, 'somevalue1'], [5, 'somevalue8'], [6, 'somevalue9'], [6, 'somevalue0'], [6, 'somevalue1'], [7, 'somevalue7']]
[[2, 'somevalue1'], [3, 'somevalue4'], [7, 'somevalue7']]

See Time Complexity. The python dict is a hashmap, its worst case is therefore O(n) if the hash function is bad and results in a lot of collisions. However that is a very rare case where every item added has the same hash and so is added to the same chain which for a major Python implementation would be extremely unlikely. The average time complexity is of course O(1).

The best method would be to check and take a look at the hashs of the objects you are using. The CPython Dict uses int PyObject_Hash (PyObject *o) which is the equivalent of hash(o).

After a quick check, I have not yet managed to find two tuples that hash to the same value, which would indicate that the lookup is O(1)

l = []
for x in range(0, 50):
    for y in range(0, 50):
        if hash((x,y)) in l:
            print "Fail: ", (x,y)
        l.append(hash((x,y)))
print "Test Finished"

For those not sure about which peak-finding algorithms to use in Python, here a rapid overview of the alternatives: https://github.com/MonsieurV/py-findpeaks

Wanting myself an equivalent to the MatLab findpeaks function, I've found that the detect_peaks function from Marcos Duarte is a good catch.

Pretty easy to use:

import numpy as np
from vector import vector, plot_peaks
from libs import detect_peaks
print('Detect peaks with minimum height and distance filters.')
indexes = detect_peaks.detect_peaks(vector, mph=7, mpd=2)
print('Peaks are: %s' % (indexes))

Which will give you:

From scipy.stats.linregress source. They use the average sum of squares method.

import numpy as np

x = np.array(x)
y = np.array(y)

# average sum of squares:
ssxm, ssxym, ssyxm, ssym = np.cov(x, y, bias=1).flat

r_num = ssxym
r_den = np.sqrt(ssxm * ssym)
r = r_num / r_den

if r_den == 0.0:
    r = 0.0
else:
    r = r_num / r_den

    if r > 1.0:
        r = 1.0
    elif r < -1.0:
        r = -1.0

Something like this:

$(myObj).attr({"data-test-1": num1, "data-test-2": num2});

Just add click event by jquery in $(document).ready() like :

$(document).ready(function(){

                  $('#YourControlID').click(function(){
                     if(Check your condtion)
                     {
                             $.messager.show({  
                                title:'My Title',  
                                msg:'The message content',  
                                showType:'fade',  
                                style:{  
                                    right:'',  
                                    bottom:''  
                                }  
                            });  
                     }
                 });
            });

Using ionic, i was able to fix this error using the command: "cordova clean"

boolean
Can be true or false.
Default value is false.

(Source: Java Primitive Variables)

Boolean
Can be a Boolean object representing true or false, or can be null.
Default value is null.

The easiest way to do this is

$myDateTime = DateTime::createFromFormat('Y-m-d', $dateString);
$newDateString = $myDateTime->format('m/d/Y');

You are first giving it the format $dateString is in. Then you are telling it the format you want $newDateString to be in.

This also avoids the use of strtotime, which can be hard to work with at times.

If you are not transforming from one date format to another, but just want the current date (or datetime) in a specific format then it's even easier:

$now = new DateTime();
$timestring = $now->format('Y-m-d h:i:s');

This other question also refers to the same topic: Convert date format yyyy-mm-dd => dd-mm-yyyy.

I was facing similar issue but it was due to space character in my file directory where I kept my java class.

Scenario given below along with solution:

   public class Sample{
      public static void main(String[] args) {
        System.out.println("Hello world, Java");
      }
}

• My Sample.java class was kept at Dir "D:\Java Programs\Sample.java"[NOTE: Package statement not present in java class].
• In command prompt, changed directory to "D:\Java Programs\", my programmed compiled but failed to run with error "Could not find or load main class"
• After all the possible solutions over SOF(nothing worked), I realized may b space causing me this issue.
• Surprisingly removal of folder name space char['Java Programs' -> 'JavaPrograms'], my program executed successfully.
  
  Hope it helps

Rename filename by searching the last character of name. For example, 

Original Filename: TestFile.txt_001
Begin Character need to be removed: _
Result: TestFile.txt

Option Explicit

Dim oWSH
Dim vbsInterpreter
Dim arg1 'As String
Dim arg2 'As String
Dim newFilename 'As string

Set oWSH = CreateObject("WScript.Shell")
vbsInterpreter = "cscript.exe"

ForceConsole()

arg1 = WScript.Arguments(0)
arg2 = WScript.Arguments(1)

WScript.StdOut.WriteLine "This is a test script."
Dim result 
result = InstrRev(arg1, arg2, -1)
If result > 0 then
    newFilename = Mid(arg1, 1, result - 1)
    Dim Fso
    Set Fso = WScript.CreateObject("Scripting.FileSystemObject")
    Fso.MoveFile arg1, newFilename
    WScript.StdOut.WriteLine newFilename
End If



Function ForceConsole()
    If InStr(LCase(WScript.FullName), vbsInterpreter) = 0 Then
        oWSH.Run vbsInterpreter & " //NoLogo " & Chr(34) &     WScript.ScriptFullName & Chr(34)
        WScript.Quit
    End If
 End Function

For Java code, Create a POJO class for your object instead of a JSONObject. and use JSONEncapsulator for your POJO class. that way order of elements depends on the order of getter setters in your POJO class. for eg. POJO class will be like

Class myObj{
String userID;
String amount;
String success;
// getter setters in any order that you want

and where you need to send your json object in response

JSONContentEncapsulator<myObj> JSONObject = new JSONEncapsulator<myObj>("myObject");
JSONObject.setObject(myObj);
return Response.status(Status.OK).entity(JSONObject).build();

The response of this line will be

{myObject : {//attributes order same as getter setter order.}}

I'm using Object.keys(chars).map(...) to loop in render

// chars = {a:true, b:false, ..., z:false}

render() {
    return (
       <div>
        {chars && Object.keys(chars).map(function(char, idx) {
            return <span key={idx}>{char}</span>;
        }.bind(this))}
        "Some text value"
       </div>
    );
}

This code works for me: check this link
This is my code when i stop and start service in activity

case R.id.buttonStart:
  Log.d(TAG, "onClick: starting srvice");
  startService(new Intent(this, MyService.class));
  break;
case R.id.buttonStop:
  Log.d(TAG, "onClick: stopping srvice");
  stopService(new Intent(this, MyService.class));
  break;
}
}
 }

And in service class:

  @Override
public void onCreate() {
    Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
    Log.d(TAG, "onCreate");

    player = MediaPlayer.create(this, R.raw.braincandy);
    player.setLooping(false); // Set looping
}

@Override
public void onDestroy() {
    Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
    Log.d(TAG, "onDestroy");
    player.stop();
}

HAPPY CODING!

To install the Jupyterthemes package directly with conda, use:

conda install -c conda-forge jupyterthemes

Then, as others have pointed out, change the theme with jt -t <theme-name>

Have you tried using:

(status,output) = commands.getstatusoutput("ps aux")

I thought this had fixed the exact same problem for me. But then my process ended up getting killed instead of failing to spawn, which is even worse..

After some testing I found that this only occurred on older versions of python: it happens with 2.6.5 but not with 2.7.2

My search had led me here python-close_fds-issue, but unsetting closed_fds had not solved the issue. It is still well worth a read.

I found that python was leaking file descriptors by just keeping an eye on it:

watch "ls /proc/$PYTHONPID/fd | wc -l"

Like you, I do want to capture the command's output, and I do want to avoid OOM errors... but it looks like the only way is for people to use a less buggy version of Python. Not ideal...

Too difficult :)

                myCommand.ExecuteNonQuery();
                }
                catch (SystemException ee)
                {
                    MessageBox.Show("Error   "+ee.ToString());
                }

            }

That's all, enjoy.

simply you can use regex to trim all spaces or minify your array items

$array = array_map(function ($item) {
    return preg_replace('/\s+/', '', $item);
}, $array);

You could use event delegation on the parent div. Or use the closest method to find the parent of the button.

The easiest of the two is probably the closest.

var id = $("button").closest("div").prop("id");

String substring(int startIndex, int endIndex)

In other words you know your string will be 10 characers long so you would do:

FinalDate = date.substring(0,9);

Assuming POSIX, simple code to capture stdout:

#include <sys/wait.h>
#include <unistd.h>
#include <string>
#include <vector>

std::string qx(const std::vector<std::string>& args) {
  int stdout_fds[2];
  pipe(stdout_fds);

  int stderr_fds[2];
  pipe(stderr_fds);

  const pid_t pid = fork();
  if (!pid) {
    close(stdout_fds[0]);
    dup2(stdout_fds[1], 1);
    close(stdout_fds[1]);

    close(stderr_fds[0]);
    dup2(stderr_fds[1], 2);
    close(stderr_fds[1]);

    std::vector<char*> vc(args.size() + 1, 0);
    for (size_t i = 0; i < args.size(); ++i) {
      vc[i] = const_cast<char*>(args[i].c_str());
    }

    execvp(vc[0], &vc[0]);
    exit(0);
  }

  close(stdout_fds[1]);

  std::string out;
  const int buf_size = 4096;
  char buffer[buf_size];
  do {
    const ssize_t r = read(stdout_fds[0], buffer, buf_size);
    if (r > 0) {
      out.append(buffer, r);
    }
  } while (errno == EAGAIN || errno == EINTR);

  close(stdout_fds[0]);

  close(stderr_fds[1]);
  close(stderr_fds[0]);

  int r, status;
  do {
    r = waitpid(pid, &status, 0);
  } while (r == -1 && errno == EINTR);

  return out;
}

You can make a simple class with public fields and no methods in Java, but it is still a class and is still handled syntactically and in terms of memory allocation just like a class. There is no way to genuinely reproduce structs in Java.

[UPDATE] ==============================================================

Respect to the [OLD] answer here below, I have discovered that it worked because I have put all the numbers in a single atomic vector; one of them was a character, so every one become characters.

If we use a list (hence, coercion does not happen) all the test pass correctly but one: 1/(1 - 0.98), which remains a numeric. This because the tol parameter is by default 100 * .Machine$double.eps and that number is far from 50 little less than the double of that. So, basically, for this kind of numbers, we have to decide our tolerance!

So if you want all test became TRUE, you can assertive::is_whole_number(x, tol = 200 * .Machine$double.eps)

Anyway, I confirm that IMO assertive remains the best solution.

Here below a reprex for this [UPDATE].

IMO the best solution comes from the assertive package (which, for the moment, solve all positive and negative examples in this thread):

  all(assertive::is_whole_number(x), na.rm = TRUE)
}

Are you able to hit that URL by browser or by PHP script? The error shown is that you could not connect. So first confirm that the URL is accessible.

Your server tells you exactly what you need : [Hint: SSLProxyEngine]

You need to add that directive to your VirtualHost before the Proxy directives :

SSLProxyEngine on
ProxyPass /primary/store https://localhost:9763/store/
ProxyPassReverse /primary/store https://localhost:9763/store/

See the doc for more detail.

If the table is compressed this will work:

alter table EVAPP_FEES add AMOUNT_TEMP NUMBER(14,2);

update EVAPP_FEES set AMOUNT_TEMP = AMOUNT;

update EVAPP_FEES set AMOUNT = null;

alter table EVAPP_FEES modify AMOUNT NUMBER(14,2);

update EVAPP_FEES set AMOUNT = AMOUNT_TEMP;

alter table EVAPP_FEES move nocompress;

alter table EVAPP_FEES drop column AMOUNT_TEMP;

alter table EVAPP_FEES compress;

you can achive it with group join

var result = (from c in Customers
          join oi in OrderItems on c.Id equals oi.Order.Customer.Id into g
          Select new { customer = c, orderItems = g});

c is Customer and g is the customers order items.

In my case, the host was unkown and instead of typing yes to the question are you sure you want to continue connecting(yes/no/[fingerprint])? I was just hitting enter .

If you want to open a windows file explorer, you should call explorer.exe

Call Shell("explorer.exe" & " " & "P:\Engineering", vbNormalFocus)

Equivalent syxntax

Shell "explorer.exe" & " " & "P:\Engineering", vbNormalFocus

If you are adding a foreign key and faced this error, it could be the value in the child table is not present in the parent table.

Let's say for the column to which the foreign key has to be added has all values set to 0 and the value is not available in the table you are referencing it.

You can set some value which is present in the parent table and then adding foreign key worked for me.

I don't think it's possible with bluetooth, but you could try looking into WiFi Peer-to-Peer,
which allows one-to-many connections.

You need to install this extension to Visual Studio 2017/2019 in order to get access to the Installer Projects.

According to the page:

This extension provides the same functionality that currently exists in Visual Studio 2015 for Visual Studio Installer projects. To use this extension, you can either open the Extensions and Updates dialog, select the online node, and search for "Visual Studio Installer Projects Extension," or you can download directly from this page.

Once you have finished installing the extension and restarted Visual Studio, you will be able to open existing Visual Studio Installer projects, or create new ones.

import csv
from sys import argv

d = open("mydata.csv", "r")

db = []

for line in csv.reader(d):
    db.append(line)

# the rest of your code with 'db' filled with your list of lists as rows and columbs of your csv file.

Jest documentation recommends the following:

If a test is failing, one of the first things to check should be whether the test is failing when it's the only test that runs. In Jest it's simple to run only one test - just temporarily change that test command to a test.only

test.only('this will be the only test that runs', () => {
   expect(true).toBe(false);
});

or

it.only('this will be the only test that runs', () => {
   expect(true).toBe(false);
});

It's almost always advisable to not use scriptlets in your JSP. They're considered bad form. Instead, try using JSTL (JSP Standard Tag Library) combined with EL (Expression Language) to run the conditional logic you're trying to do. As an added benefit, JSTL also includes other important features like looping.

Instead of:

<%String user=request.getParameter("user"); %>
<%if(user == null || user.length() == 0){
    out.print("I see! You don't have a name.. well.. Hello no name");   
}
else {%>
    <%@ include file="response.jsp" %>
<% } %>

Use:

<c:choose>
    <c:when test="${empty user}">
        I see!  You don't have a name.. well.. Hello no name
    </c:when>
    <c:otherwise>
        <%@ include file="response.jsp" %>
    </c:otherwise>
</c:choose>

Also, unless you plan on using response.jsp somewhere else in your code, it might be easier to just include the html in your otherwise statement:

<c:otherwise>
    <h1>Hello</h1>
    ${user}
</c:otherwise>

Also of note. To use the core tag, you must import it as follows:

 <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

You want to make it so the user will receive a message when the user submits a username. The easiest way to do this is to not print a message at all when the "user" param is null. You can do some validation to give an error message when the user submits null. This is a more standard approach to your problem. To accomplish this:

In scriptlet:

<% String user = request.getParameter("user");
   if( user != null && user.length() > 0 ) {
       <%@ include file="response.jsp" %>
   }
%>

In jstl:

<c:if test="${not empty user}">
    <%@ include file="response.jsp" %>
</c:if>

though i take the url from an input, it's easy adjustable to the real url.

var value = 0;

$('#check').click(function()
{
    var originalURL = $('#test').val();
    var exists = originalURL.indexOf('&view-all');

    if(exists === -1)
    {
        $('#test').val(originalURL + '&view-all=value' + value++);
    }
    else
    {
        $('#test').val(originalURL.substr(0, exists + 15) + value++);
    }
});

You can use one of the many Arrays.binarySearch() methods. Keep in mind that the array must be sorted first.

The exception probably comes from the parseDouble() calls. Check that the values given to that function really reflect a double.

XAMPP is more powerful and resource taking than WAMP.
WAMP provides support for MySQL and PHP.
XAMPP provides support for MYSQL, PHP and PERL

XAMPP also has SSL feature while WAMP doesnt.
If your applications need to deal with native web apps only, Go for WAMP. If you need advanced features as stated above, go for XAMPP.

As of priority, you cant run both together with default installation as XAMPP gets a higher priority and it takes up ports. So WAMP cant be run in parallel with XAMPP.

Just Overload the default constructor of Model class and pass any relevant parameter which you may or may not use. By this you can easily supply default values for attributes. Below is an example.

I had a somehow similar problem working with AFNetworking from a Swift codebase so I'm just leaving this here in the remote case someone is as unlucky as me having to work in such a setup. If you are, I feel you buddy, stay strong!

The operation was failing due to "unacceptable content-type", despite me actually setting the acceptableContentTypes with a Set containing the content type value in question.

The solution for me was to tweak the Swift code to be more Objective-C friendly, I guess:

serializer.acceptableContentTypes = NSSet(array: ["application/xml", "text/xml", "text/plain"]) as Set<NSObject>

The whole point is to write implementation-independent code. unsigned char is not guaranteed to be an 8-bit type. uint8_t is (if available).

My code :

$("input.numeric").keypress(function(e) { /* pour les champs qui ne prennent que du numeric en entrée */          
            var key = e.charCode || e.keyCode || 0;                     
            var keychar = String.fromCharCode(key);
            /*alert("keychar:"+keychar + " \n charCode:" + e.charCode + " \n key:" +key);*/
            if (  ((key == 8 || key == 9 || key == 46 || key == 35 || key == 36 || (key >= 37 && key <= 40)) && e.charCode==0) /* backspace, end, begin, top, bottom, right, left, del, tab */
                    || (key >= 48 && key <= 57) ) { /* 0-9 */
                return;
            } else {
                e.preventDefault();
            }
        });

If you paste the listing into your word processor instead of Notepad, (since each file name is in quotation marks with the full path name), you can highlight all the stuff you don't want on the first file, then use Find and Replace to replace every occurrence of that with nothing. Same with the ending quote (").

It makes a nice clean list of file names.

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

Manipulating an Access database from Java without ODBC

You can leverage on Mongo Shell Extensions. It's a single .js import that you can append to your $HOME/.mongorc.js, or programmatically, if you're coding in Node.js/io.js too.

Sample

For each distinct value of field counts the occurrences in documents optionally filtered by query

> db.users.distinctAndCount('name', {name: /^a/i})

{
  "Abagail": 1,
  "Abbey": 3,
  "Abbie": 1,
  ...
}

The field parameter could be an array of fields

> db.users.distinctAndCount(['name','job'], {name: /^a/i})

{
  "Austin,Educator" : 1,
  "Aurelia,Educator" : 1,
  "Augustine,Carpenter" : 1,
  ...
}

To make all 3: Model, Controller & Migration Schema of table

write in your console: php artisan make:model NameOfYourModel -mcr

I had the same problem and fixed it with this command:

$ git push -u origin master

From the help file the -u basically sets the default for pulls:

-u, --set-upstream`

  For every branch that is up to date or successfully pushed, add 
  upstream (tracking) reference, used by argument-less git-pull(1) and
  other commands. For more information, see branch.<name>.merge in 
  git-config(1).

The best you can get with simple styles would be something like:

.likeabutton {
    text-decoration: none; font: menu;
    display: inline-block; padding: 2px 8px;
    background: ButtonFace; color: ButtonText;
    border-style: solid; border-width: 2px;
    border-color: ButtonHighlight ButtonShadow ButtonShadow ButtonHighlight;
}
.likeabutton:active {
    border-color: ButtonShadow ButtonHighlight ButtonHighlight ButtonShadow;
}

(Possibly with some kind of fix to stop IE6-IE7 treating focused buttons as being ‘active’.)

This won't necessarily look exactly like the buttons on the native desktop, though; indeed, for many desktop themes it won't be possible to reproduce the look of a button in simple CSS.

However, you can ask the browser to use native rendering, which is best of all:

.likeabutton {
    appearance: button;
    -moz-appearance: button;
    -webkit-appearance: button;
    text-decoration: none; font: menu; color: ButtonText;
    display: inline-block; padding: 2px 8px;
}

Unfortunately, as you may have guessed from the browser-specific prefixes, this is a CSS3 feature that isn't suppoorted everywhere yet. In particular IE and Opera will ignore it. But if you include the other styles as backup, the browsers that do support appearance drop that property, preferring the explicit backgrounds and borders!

What you might do is use the appearance styles as above by default, and do JavaScript fixups as necessary, eg.:

<script type="text/javascript">
    var r= document.documentElement;
    if (!('appearance' in r || 'MozAppearance' in r || 'WebkitAppearance' in r)) {
        // add styles for background and border colours
        if (/* IE6 or IE7 */)
            // add mousedown, mouseup handlers to push the button in, if you can be bothered
        else
            // add styles for 'active' button
    }
</script>

Working example:

git mv ./src/images/poster_video.PNG ./src/images/poster_video.png

Figured I'd post a project I recently came across to get dominant color:

Color Thief

A script for grabbing the dominant color or a representative color palette from an image. Uses javascript and canvas.

The other solutions mentioning and suggesting dominant color never really answer the question in proper context ("in javascript"). Hopefully this project will help those who want to do just that.

Use Path.GetFileNameWithoutExtension().

In SQL, the order of the output is not defined unless you specify it in the ORDER BY clause.

Try this:

SELECT  *

JOIN    two
ON      one.one_name = two.one_name
ORDER BY
        one.id

According to this answer, adding the -t flag will prevent the container from exiting when running in the background. You can then use docker exec -i -t <image> /bin/bash to get into a shell prompt.

docker run -t -d <image> <command>

It seems that the -t option isn't documented very well, though the help says that it "allocates a pseudo-TTY."

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.

There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.

I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException and Application.ThreadException, as appropriate.

I just lost a few hours on this one. My conclusion:

• Depending on version and whatever other local conditions, autoconf will spit out the message about AC_MSG_ERROR undefined when it encounters ANY undefined macro. The AC_MSG_ERROR is a red herring. The causes for an undefined macro can be:
  • A typo in a macro name in the file, or a local macro which has not been shipped with the tarball
  • Missing a package which would have come with a set of autoconf macros, one of which is used in the file. pkg-config is often the missing one (because of, e.g.,PKG_CHECK_MODULES), but this could be any other package supplying a needed but absent macro. The vicious thing of course, is that this happens before the still not existing configure script could check for the missing package...

The print() function returns None. You are trying to index None. You can not, because 'NoneType' object is not subscriptable.

Put the [0] inside the brackets. Now you're printing everything, and not just the first term.

Where do you want to see the output?

Messages being output via Debug.Print will be displayed in the immediate window which you can open by pressing Ctrl+G.

For eclipselink, only the following dependency is sufficient to generate metamodel. Nothing else is needed.

    <dependency>
        <groupId>org.eclipse.persistence</groupId>
        <artifactId>org.eclipse.persistence.jpa.modelgen.processor</artifactId>
        <version>2.5.1</version>

you may change your loop condition according to following code, when length of l is smaller than buffer size it means that it reached end of file

while (True):
    print "Receiving..."
    l = c.recv(1024)        
    f.write(l)
    if len(l) < 1024:
        break

There is a property of the built-in window.location object that will provide that for the current window.

// If URL is http://www.somedomain.com/account/search?filter=a#top

window.location.pathname // /account/search

// For reference:

window.location.host     // www.somedomain.com (includes port if there is one)
window.location.hostname // www.somedomain.com
window.location.hash     // #top
window.location.href     // http://www.somedomain.com/account/search?filter=a#top
window.location.port     // (empty string)
window.location.protocol // http:
window.location.search   // ?filter=a  

Update, use the same properties for any URL:

It turns out that this schema is being standardized as an interface called URLUtils, and guess what? Both the existing window.location object and anchor elements implement the interface.

So you can use the same properties above for any URL — just create an anchor with the URL and access the properties:

var el = document.createElement('a');
el.href = "http://www.somedomain.com/account/search?filter=a#top";

el.host        // www.somedomain.com (includes port if there is one[1])
el.hostname    // www.somedomain.com
el.hash        // #top
el.href        // http://www.somedomain.com/account/search?filter=a#top
el.pathname    // /account/search
el.port        // (port if there is one[1])
el.protocol    // http:
el.search      // ?filter=a

[1]: Browser support for the properties that include port is not consistent, See: http://jessepollak.me/chrome-was-wrong-ie-was-right

This works in the latest versions of Chrome and Firefox. I do not have versions of Internet Explorer to test, so please test yourself with the JSFiddle example.

JSFiddle example

There's also a coming URL object that will offer this support for URLs themselves, without the anchor element. Looks like no stable browsers support it at this time, but it is said to be coming in Firefox 26. When you think you might have support for it, try it out here.

Now we know what the actual error is can formulate an answer.

Not allowed to load local resource

is a Security exception built into Chrome and other modern browsers. The wording may be different but in some way shape or form they all have security exceptions in place to deal with this scenario.

In the past you could override certain settings or apply certain flags such as

--disable-web-security --allow-file-access-from-files --allow-file-access

in Chrome (See https://stackoverflow.com/a/22027002/692942)

It's there for a reason

At this point though it's worth pointing out that these security exceptions exist for good reason and trying to circumvent them isn't the best idea.

There is another way

As you have access to Classic ASP already you could always build a intermediary page that serves the network based files. You do this using a combination of the ADODB.Stream object and the Response.BinaryWrite() method. Doing this ensures your network file locations are never exposed to the client and due to the flexibility of the script it can be used to load resources from multiple locations and multiple file types.

Here is a basic example (getfile.asp);

<%
Option Explicit

Dim s, id, bin, file, filename, mime

id = Request.QueryString("id")

'id can be anything just use it as a key to identify the 
'file to return. It could be a simple Case statement like this
'or even pulled from a database.
Select Case id
Case "TESTFILE1"
  'The file, mime and filename can be built-up anyway they don't 
  'have to be hard coded.
  file = "\\server\share\Projecten\Protocollen\346\Uitvoeringsoverzicht.xls"     
  mime = "application/vnd.ms-excel"
  'Filename you want to display when downloading the resource.
  filename = "Uitvoeringsoverzicht.xls"

'Assuming other files 
Case ...
End Select

If Len(file & "") > 0 Then
  Set s = Server.CreateObject("ADODB.Stream")
  s.Type = adTypeBinary 'adTypeBinary = 1 See "Useful Links"
  Call s.Open()
  Call s.LoadFromFile(file)
  bin = s.Read()

  'Clean-up the stream and free memory
  Call s.Close()
  Set s = Nothing

  'Set content type header based on mime variable
  Response.ContentType = mime
  'Control how the content is returned using the 
  'Content-Disposition HTTP Header. Using "attachment" forces the resource
  'to prompt the client to download while "inline" allows the resource to
  'download and display in the client (useful for returning images
  'as the "src" of a <img> tag).
  Call Response.AddHeader("Content-Disposition", "attachment;filename=" & filename)
  Call Response.BinaryWrite(bin)
Else
  'Return a 404 if there's no file.
  Response.Status = "404 Not Found"
End If
%>

^{This example is pseudo coded and as such is untested.}

This script can then be used in <a> like this to return the resource;

<a href="/getfile.asp?id=TESTFILE1">Click Here</a>

The could take this approach further and consider (especially for larger files) reading the file in chunks using Response.IsConnected to check whether the client is still there and s.EOS property to check for the end of the stream while the chunks are being read. You could also add to the querystring parameters to set whether you want the file to return in-line or prompt to be downloaded.

I did the following to get my Mac to see the devices again:

• Run android update adb
• Run adb kill-server
• Run adb start-server

At this point, calling adb devices started returning devices again. Now run or debug your project to test it on your device.

import platform
platform.architecture()

From the Python docs:

Queries the given executable (defaults to the Python interpreter binary) for various architecture information.

Returns a tuple (bits, linkage) which contain information about the bit architecture and the linkage format used for the executable. Both values are returned as strings.

You were on the right track. IrfanView sets the background for transparency the same as the viewing color around the image.

You just need to re-open the image with IrfanView after changing the view color to white.

To change the viewing color in Irfanview go to:

Options > Properties/Settings > Viewing > Main window color

The Below code make the bitmap perfectly with same size of the imageview. Get the bitmap image height and width and then calculate the new height and width with the help of imageview's parameters. That give you required image with best aspect ratio.

int bwidth=bitMap1.getWidth();
int bheight=bitMap1.getHeight();
int swidth=imageView_location.getWidth();
int sheight=imageView_location.getHeight();
new_width=swidth;
new_height = (int) Math.floor((double) bheight *( (double) new_width / (double) bwidth));
Bitmap newbitMap = Bitmap.createScaledBitmap(bitMap1,new_width,new_height, true);
imageView_location.setImageBitmap(newbitMap)

I think :hover was missing in above answers. So following would do the needful.(if css was required)

#myDiv:hover
{
    cursor: pointer;
}

In place of the Memory storage engine, one can consider MySQL Cluster. It is said to give similar performance but to support disk-backed operation for durability. I've not tried it, but it looks promising (and been in development for a number of years).

You can find the official MySQL Cluster documentation here.

There seems to be a confusion about the declaration.

When strategycomes before {RANDOM, IMMEDIATE, SEARCH} as in the following,

enum strategy {RANDOM, IMMEDIATE, SEARCH};

you are creating a new type named enum strategy. However, when declaring the variable, you need to use enum strategy itself. You cannot just use strategy. So the following is invalid.

enum strategy {RANDOM, IMMEDIATE, SEARCH};
strategy a;

While, the following is valid

enum strategy {RANDOM, IMMEDIATE, SEARCH};

enum strategy queen = RANDOM;
enum strategy king = SEARCH;
enum strategy pawn[100];

When strategy comes after {RANDOM, IMMEDIATE, SEARCH}, you are creating an anonymous enum and then declaring strategy to be a variable of that type.

So now, you can do something like

enum {RANDOM, IMMEDIATE, SEARCH} strategy;
strategy = RANDOM;

However, you cannot declare any other variable of type enum {RANDOM, IMMEDIATE, SEARCH} because you have never named it. So the following is invalid

enum {RANDOM, IMMEDIATE, SEARCH} strategy;
enum strategy a = RANDOM;

You can combine both the definitions too

enum strategy {RANDOM, IMMEDIATE, SEARCH} a, b;

a = RANDOM;
b = SEARCH;
enum strategy c = IMMEDIATE;

Typedef as noted before is used for creating a shorter variable declaration.

typedef enum {RANDOM, IMMEDIATE, SEARCH} strategy;

Now you have told compiler that enum {RANDOM, IMMEDIATE, SEARCH} is synonomous to strategy. So now you can freely use strategy as variable type. You don't need to type enum strategy anymore. The following is valid now

strategy x = RANDOM;

You can also combine Typedef along with enum name to get

typedef enum strategyName {RANDOM, IMMEDIATE, SEARCH} strategy;

There's not much advantage of using this method apart from the fact that you can now use strategy and enum strategyName interchangeably.

typedef enum strategyName {RANDOM, IMMEDIATE, SEARCH} strategy;

enum strategyName a = RANDOM;
strategy b = SEARCH;

The corrected code is

import urllib.request
fhand = urllib.request.urlopen('http://data.pr4e.org/romeo.txt')
counts = dict()
for line in fhand: 
    words = line.decode().split() 
for word in words: 
    counts[word] = counts.get(word, 0) + 1 
print(counts) 

running the code above produces

{'Who': 1, 'is': 1, 'already': 1, 'sick': 1, 'and': 1, 'pale': 1, 'with': 1, 'grief': 1}

Another options with purrr package:

library(dplyr)

df <- data.frame(a = NA,
                 b = seq(1:5), 
                 c = c(rep(1, 4), NA))

df %>% purrr::discard(~all(is.na(.)))
df %>% purrr::keep(~!all(is.na(.)))

Use unshift, which modifies the existing array by adding the arguments to the beginning:

TheArray.unshift(TheNewObject);

1. Right-click an object in Chrome's console and select Store as Global Variable from the context menu. It will return something like temp1 as the variable name.

2. Chrome also has a copy() method, so copy(temp1) in the console should copy that object to your clipboard.

Note on Recursive Objects: If you're trying to copy a recursive object, you will get [object Object]. The way out is to copy(JSON.stringify(temp1)) , the object will be fully copied to your clipboard as a valid JSON, so you'd be able to format it as you wish, using one of many resources.

On the formula menu just Select "Default Values for Nulls" then just add all the fields like the below:

{@Table.Field1} + {@Table.Field2} + {@Table.Field3} + {@Table.Field4} + {@Table.Field5}

use getContext() instead of MainActivity.this

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

At the risk of irritating you;

You're asking the wrong question. You don't need a reason NOT to deviate from the defaults, but the other way around. You need a reason to do so. Timeouts are absolutely essential when running a web server and to disable that setting without a reason is inherently contrary to good practice, even if it's running on a web server that happens to have a timeout directive of its own.

Now, as for the real answer; probably it doesn't matter at all in this particular case, but it's bad practice to go by the setting of a separate system. What if the script is later run on a different server with a different timeout? If you can safely say that it will never happen, fine, but good practice is largely about accounting for seemingly unlikely events and not unnecessarily tying together the settings and functionality of completely different systems. The dismissal of such principles is responsible for a lot of pointless incompatibilities in the software world. Almost every time, they are unforeseen.

What if the web server later is set to run some other runtime environment which only inherits the timeout setting from the web server? Let's say for instance that you later need a 15-year-old CGI program written in C++ by someone who moved to a different continent, that has no idea of any timeout except the web server's. That might result in the timeout needing to be changed and because PHP is pointlessly relying on the web server's timeout instead of its own, that may cause problems for the PHP script. Or the other way around, that you need a lesser web server timeout for some reason, but PHP still needs to have it higher.

It's just not a good idea to tie the PHP functionality to the web server because the web server and PHP are responsible for different roles and should be kept as functionally separate as possible. When the PHP side needs more processing time, it should be a setting in PHP simply because it's relevant to PHP, not necessarily everything else on the web server.

In short, it's just unnecessarily conflating the matter when there is no need to.

Last but not least, 'stillstanding' is right; you should at least rather use set_time_limit() than ini_set().

Hope this wasn't too patronizing and irritating. Like I said, probably it's fine under your specific circumstances, but it's good practice to not assume your circumstances to be the One True Circumstance. That's all. :)

Using zip function we can get both element and index.

countries = ['Pakistan','India','China','Russia','USA']

for index, element zip(range(0,countries),countries):

         print('Index : ',index)
         print(' Element : ', element,'\n')

output : Index : 0 Element : Pakistan ...

jsonb in Postgres 9.4+

You can use the same query as below, just with jsonb_array_elements().

But rather use the jsonb "contains" operator @> in combination with a matching GIN index on the expression data->'objects':

CREATE INDEX reports_data_gin_idx ON reports
USING gin ((data->'objects') jsonb_path_ops);

SELECT * FROM reports WHERE data->'objects' @> '[{"src":"foo.png"}]';

Since the key objects holds a JSON array, we need to match the structure in the search term and wrap the array element into square brackets, too. Drop the array brackets when searching a plain record.

More explanation and options:

• Index for finding an element in a JSON array

json in Postgres 9.3+

Unnest the JSON array with the function json_array_elements() in a lateral join in the FROM clause and test for its elements:

SELECT data::text, obj
FROM   reports r, json_array_elements(r.data#>'{objects}') obj
WHERE  obj->>'src' = 'foo.png';

db<>fiddle here
_{Old sqlfiddle}

The CTE (WITH query) just substitutes for a table reports.
Or, equivalent for just a single level of nesting:

SELECT *
FROM   reports r, json_array_elements(r.data->'objects') obj
WHERE  obj->>'src' = 'foo.png';

->>, -> and #> operators are explained in the manual.

Both queries use an implicit JOIN LATERAL.

For newer pandas versions

df.index = df.index.rename('new name')

or

df.index.rename('new name', inplace=True)

The latter is required if a data frame should retain all its properties.

This will get you the timezone as a PHP variable. I wrote a function using jQuery and PHP. This is tested, and does work!

On the PHP page where you are want to have the timezone as a variable, have this snippet of code somewhere near the top of the page:

<?php    
    session_start();
    $timezone = $_SESSION['time'];
?>

This will read the session variable "time", which we are now about to create.

On the same page, in the <head> section, first of all you need to include jQuery:

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>

Also in the <head> section, paste this jQuery:

<script type="text/javascript">
    $(document).ready(function() {
        if("<?php echo $timezone; ?>".length==0){
            var visitortime = new Date();
            var visitortimezone = "GMT " + -visitortime.getTimezoneOffset()/60;
            $.ajax({
                type: "GET",
                url: "http://example.com/timezone.php",
                data: 'time='+ visitortimezone,
                success: function(){
                    location.reload();
                }
            });
        }
    });
</script>

You may or may not have noticed, but you need to change the url to your actual domain.

One last thing. You are probably wondering what the heck timezone.php is. Well, it is simply this: (create a new file called timezone.php and point to it with the above url)

<?php
    session_start();
    $_SESSION['time'] = $_GET['time'];
?>

If this works correctly, it will first load the page, execute the JavaScript, and reload the page. You will then be able to read the $timezone variable and use it to your pleasure! It returns the current UTC/GMT time zone offset (GMT -7) or whatever timezone you are in.

You can read more about this on my blog

For a production system, you can use this configuration :

--ACCESS DB
REVOKE CONNECT ON DATABASE nova FROM PUBLIC;
GRANT  CONNECT ON DATABASE nova  TO user;

--ACCESS SCHEMA
REVOKE ALL     ON SCHEMA public FROM PUBLIC;
GRANT  USAGE   ON SCHEMA public  TO user;

--ACCESS TABLES
REVOKE ALL ON ALL TABLES IN SCHEMA public FROM PUBLIC ;
GRANT SELECT                         ON ALL TABLES IN SCHEMA public TO read_only ;
GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO read_write ;
GRANT ALL                            ON ALL TABLES IN SCHEMA public TO admin ;

You can always use MacPorts...

Next to being in the wrong directory I just tripped about another variant:

I had a File.open(my_file).each {|line| puts line} exploding but there was something by that name in the directory I was working in (ls in the command line showed the name). I checked with a File.exists?(my_file) which strangely returned false. Explanation: my_file was a symlink which target didn't exist anymore! Since File.exists? will follow a symlink it will say false though the link is still there.

A more recent solution to this problem: Use the more recent sdl libs on

"https://buildbot.libsdl.org/sdl-builds/sdl-visualstudio/?C=M;O=D"

They seem to have fixed the problem, although it's only the 32 bit library (I think).

use the String.Trim() function.

string foo = "   hello ";
string bar = foo.Trim();

Console.WriteLine(bar); // writes "hello"

This minimal CMakeLists.txt file compiles a simple shared library:

cmake_minimum_required(VERSION 2.8)

project (test)
set(CMAKE_BUILD_TYPE Release)

include_directories(${CMAKE_CURRENT_SOURCE_DIR}/include)
add_library(test SHARED src/test.cpp)

However, I have no experience copying files to a different destination with CMake. The file command with the COPY/INSTALL signature looks like it might be useful.

As some people have mentioned, Javascript is the way to go. Bear in mind that the "validation" here is only by file extension, it won't validate that the file is a real excel spreadsheet!

In Android Studio 3.4.1, you can use the search feature of Android Studio to find "Device File Explorer" and then go to the /data/data/package_name/database directory of your emulator.

MAC OS

I had the same problem on Mac OS(Mojave) and solved the problem as mentioned on this link - Openssl issue.

1. If you do not have Homebrew or don't know what is Homebrew:

   /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. Or if you already have Homebrew installed:

brew update && brew upgrade
brew uninstall --ignore-dependencies openssl; brew install https://github.com/tebelorg/Tump/releases/download/v1.0.0/openssl.rb

Update: Keep in mind, that I had to use --ignore-dependencies flag, because other packages installed that depend on OpenSSL.

Additional if the problem is caused after using pyenv, you can fix it by using:

brew reinstall python

I already wrote up the answer to this but it seems to have been deleted. The issue was that YUI added background-color:white to the HTML element. I overwrote that and everything was easy to handle from there.

If you want to be able to call the func with or without the parameter you can create a second func of the same name which calls the other.

func test(firstThing: Int?) {
    if firstThing != nil {
        print(firstThing!)
    }
    print("done")
}

func test() {
    test(firstThing: nil)
}

now you can call a function named test without or without the parameter.

// both work
test()
test(firstThing: 5)

So I wanted to add another PHP way of solving this, since everyone loves PHP. There's a little bit of refactoring I would like to do, like using a regexpression match against the dictionary file, but right now I'm just loading the entire dictionary file into a wordList.

I did this using a linked list idea. Each Node has a character value, a location value, and a next pointer.

The location value is how I found out if two nodes are connected.

1     2     3     4
11    12    13    14
21    22    23    24
31    32    33    34

So using that grid, I know two nodes are connected if the first node's location equals the second nodes location +/- 1 for the same row, +/- 9, 10, 11 for the row above and below.

I use recursion for the main search. It takes a word off the wordList, finds all the possible starting points, and then recursively finds the next possible connection, keeping in mind that it can't go to a location it's already using (which is why I add $notInLoc).

Anyway, I know it needs some refactoring, and would love to hear thoughts on how to make it cleaner, but it produces the correct results based on the dictionary file I'm using. Depending on the number of vowels and combinations on the board, it takes about 3 to 6 seconds. I know that once I preg_match the dictionary results, that will reduce significantly.

What about:

parseFloat(str.replace(' ', '').replace('.', '').replace(',', '.'));

You may be forgetting something. Before #include <iostream>, write #include <stdafx.h> and maybe that will help. Then, when you are done writing, click test, than click output from build, then when it is done processing/compiling, press Ctrl+F5 to open the Command Prompt and it should have the output and "press any key to continue."

Open 'postgresql.conf' in you favourite editor. Look for the variable 'unix_socket_directories', it will most likely look like this:

unix_socket_directories = '/private/tmp/'

Change the line to this:

unix_socket_directories = '/var/pgsql_socket/'

Note if you want the socket files in more than one directory comma separate them.

Add more than one class based on the condition:

<div ng-click="AbrirPopUp(s)" 
ng-class="{'class1 class2 class3':!isNew, 
           'class1 class4': isNew}">{{ isNew }}</div>

Apply: class1 + class2 + class3 when isNew=false,

Apply: class1+ class4 when isNew=true

and has lower precedence, mostly we use it as a control-flow modifier such as if:

next if widget = widgets.pop

becomes

widget = widgets.pop and next

For or:

raise "Not ready!" unless ready_to_rock?

becomes

ready_to_rock? or raise "Not ready!"

I prefer to use if but not and, because if is more intelligible, so I just ignore and and or.

Refer to "Using “and” and “or” in Ruby" for more information.

I've had a similar issue with this error. In my case, I was entering the incorrect password for the Keystore.

I changed the password for the Keystore to match what I was entering (I didn't want to change the password I was entering), but it still gave the same error.

keytool -storepasswd -keystore keystore.jks

Problem was that I also needed to change the Key's password within the Keystore.

When I initially created the Keystore, the Key was created with the same password as the Keystore (I accepted this default option). So I had to also change the Key's password as follows:

keytool -keypasswd  -alias my.alias -keystore keystore.jks

And it's maybe also handy to know that BigTable is not a relational database (like MySQL) but a huge (distributed) hash table which has very different characteristics. You can play around with (a limited version) of BigTable yourself on the Google AppEngine platform.

Next to Hadoop mentioned above there are many other implementations that try to solve the same problems as BigTable (scalability, availability). I saw a nice blog post yesterday listing most of them here.

I think it is more pythonic:

aList.remove(123)
aList.insert(0, 2014)

more useful:

def shuffle(list, to_delete, to_shuffle, index):
    list.remove(to_delete)
    list.insert(index, to_shuffle)
    return

list = ['a', 'b']
shuffle(list, 'a', 'c', 0)
print list
>> ['c', 'b']

Even though an answer has already been accepted, I would like to present what might even be the simplest option:

$ mysqladmin -u bob -p -i 1 processlist

This will print the current queries on your screen every second.

• -u The mysql user you want to execute the command as
• -p Prompt for your password (so you don't have to save it in a file or have the command appear in your command history)
• i The interval in seconds.
• Use the --verbose flag to show the full process list, displaying the entire query for each process. (Thanks, nmat)

There is a possible downside: fast queries might not show up if they run between the interval that you set up. IE: My interval is set at one second and if there is a query that takes .02 seconds to run and is ran between intervals, you won't see it.

Use this option preferably when you quickly want to check on running queries without having to set up a listener or anything else.

Actually, looking through MSDN, the functions they recommend using (instead of Protected Storage) are:

• CryptProtectData
• CryptUnprotectData

The link for CryptProtectData is at CryptProtectData function.

My solution to this error was that a copy and paste from another project that had a reference to @Model.Id. This particular page didn't have a model but the error line was so far off from the actual error I about never found it!

You are getting this error because you are not giving full path. (C:\Users...\file.exe) If you want to remove this error then either give full path or copy that application (you want to open) to the folder where your project(.exe) is present/saved.

#include <windows.h>
using namespace std;
int main()
{
  system ("start C:\\Users\\Folder\\chrome.exe https://www.stackoverflow.com"); //for opening stackoverflow through google chrome , if chorme.exe is in that folder..
  return 0;
}

I'd use absolute positioning:

#play_button {
    position:absolute;
transition: .5s ease;
    left: 202px;
    top: 198px;

}

Another suggestion is to do that way:

string = "abcd\n"
print(string.replace("\n","\\n"))

But be aware that the print function actually print to the terminal the "\n", your terminal interpret that as a newline, that's it. So, my solution just change the newline in \ + n

Use

btnTest_Click( this, new EventArgs() );

if the file containing that link tag is in the root dir of the project, then the correct path would be "css/styles.css"

you have to change the -> sourceCompatibility = '1.7' in build.Gradle

pi Radians = 180 degrees

So 1 degree = pi/180 radians

You can use the NotMapped attribute data annotation to instruct Code-First to exclude a particular property

public class Customer
{
    public int CustomerID { set; get; }
    public string FirstName { set; get; } 
    public string LastName{ set; get; } 
    [NotMapped]
    public int Age { set; get; }
}

[NotMapped] attribute is included in the System.ComponentModel.DataAnnotations namespace.

You can alternatively do this with Fluent API overriding OnModelCreating function in your DBContext class:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
   modelBuilder.Entity<Customer>().Ignore(t => t.LastName);
   base.OnModelCreating(modelBuilder);
}

http://msdn.microsoft.com/en-us/library/hh295847(v=vs.103).aspx

The version I checked is EF 4.3, which is the latest stable version available when you use NuGet.

Edit : SEP 2017

Asp.NET Core(2.0)

Data annotation

If you are using asp.net core (2.0 at the time of this writing), The [NotMapped] attribute can be used on the property level.

public class Customer
{
    public int Id { set; get; }
    public string FirstName { set; get; } 
    public string LastName { set; get; } 
    [NotMapped]
    public int FullName { set; get; }
}

        base.OnModelCreating(modelBuilder);
    }
    public DbSet<Customer> Customers { get; set; }
}

these code is converted code from gbk answer in swift 4

1.in your main controllview :

 if let filePath = Bundle.main.path(forResource: "clip", ofType: "mp4") {
            let fileURL = NSURL(fileURLWithPath: filePath)
            videoPlayer = VideoPlayer(urlAsset: fileURL, view: playerView)
            if let player = videoPlayer {
                player.playerRate = 1.00
            }
        }

2. you need VideoPlayer class

3. and a PlayerView class to create a videoview:

     import AVFoundation
   
     import UIKit
   
     class PlayerView: UIView {
   
   
   override class var layerClass: AnyClass {
       get {
         return AVPlayerLayer.self
       }
   }
   
   
   var player:AVPlayer? {
       set {
           if let layer = layer as? AVPlayerLayer {
               layer.player = player
           }
       }
       get {
           if let layer = layer as? AVPlayerLayer {
               return layer.player
           } else {
               return nil
           }
       }
   }
   }
   

The Trace messages can occur in the output window as well, even if you're not in debug mode. You just have to make sure the the TRACE compiler constant is defined.

int myArray[10] = { 5, 5, 5, 5, 5, 5, 5, 5, 5, 5 }; // All elements of myArray are 5
int myArray[10] = { 0 };    // Will initialize all elements to 0
int myArray[10] = { 5 };    // Will initialize myArray[0] to 5 and other elements to 0
static int myArray[10]; // Will initialize all elements to 0
/************************************************************************************/
int myArray[10];// This will declare and define (allocate memory) but won’t initialize
int i;  // Loop variable
for (i = 0; i < 10; ++i) // Using for loop we are initializing
{
    myArray[i] = 5;
}
/************************************************************************************/
int myArray[10] = {[0 ... 9] = 5}; // This works only in GCC

The Html Agility Pack has been mentioned before - if you are going for speed, you might also want to check out the Majestic-12 HTML parser. Its handling is rather clunky, but it delivers a really fast parsing experience.

Try redirecting the output to Out-Null. Like so,

$key = & 'gpg' --decrypt "secret.gpg" --quiet --no-verbose | out-null

If you are trying to test your app coded in android studio through your android phone, its generally the issue of your phone. Just uncheck all the USB debugging options and toggle the developer options to OFF. Then restart your phone and switch the developer and USB debugging on. You are ready to go!

Unless your application has specially needs, I think you have 2 approaches:

1. Do not use session at all
2. Use session as is and perform fine tuning as joel mentioned.

Session is not only thread-safe but also state-safe, in a way that you know that until the current request is completed, every session variable wont change from another active request. In order for this to happen you must ensure that session WILL BE LOCKED until the current request have completed.

You can create a session like behavior by many ways, but if it does not lock the current session, it wont be 'session'.

For the specific problems you mentioned I think you should check HttpContext.Current.Response.IsClientConnected. This can be useful to to prevent unnecessary executions and waits on the client, although it cannot solve this problem entirely, as this can be used only by a pooling way and not async.

I finished my time alert with a unwanted effect.... Browsers add stuff to windows. My script is an aptated one and I will show after the following text.

I found a CSS script for popups, which doesn't have unwanted browser stuff. This was written by Prakash:- https://codepen.io/imprakash/pen/GgNMXO. This script I will show after the following text.

This CSS script above looks professional and is alot more tidy. This button could be a clickable company logo image. By suppressing this button/image from running a function, this means you can run this function from inside javascript or call it with CSS, without it being run by clicking it.

This popup alert stays inside the window that popped it up. So if you are a multi-tasker you won't have trouble knowing what alert goes with what window.

The statements above are valid ones.... (Please allow). How these are achieved will be down to experimentation, as my knowledge of CSS is limited at the moment, but I learn fast.

CSS menus/DHTML use mouseover(valid statement).

I have a CSS menu script of my own which is adapted from 'Javascript for dummies' that pops up a menu alert. This works, but text size is limited. This hides under the top window banner. This could be set to be timed alert. This isn't great, but I will show this after the following text.

The Prakash script above I feel could be the answer if you can adapt it.

Scripts that follow:- My adapted timed window alert, Prakash's CSS popup script, my timed menu alert.

You can use this for color without alpha:

String hexColor = String.format("#%06X", (0xFFFFFF & intColor));

or this with alpha:

String hexColor = String.format("#%08X", (0xFFFFFFFF & intColor));

To float a div to the right pull-right is the recommend way, I feel you are doing things right may be you only need to use text-align:right;

  <div class="container">
     <div class="row-fluid">
      <div class="span6">
           <p>Text left</p>
      </div>
      <div class="span6 pull-right" style="text-align:right">
           <p>text right</p>
      </div>
  </div>
 </div>      
 </div>

Assuming you're interested in whether the variable has been explicitly assigned a value or not, the answer is "not really". There's absolutely no difference between a field (instance variable or class variable) which hasn't been explicitly assigned at all yet, and one which has been assigned its default value - 0, false, null etc.

Now if you know that once assigned, the value will never reassigned a value of null, you can use:

if (box != null) {
    box.removeFromCanvas();
}

(and that also avoids a possible NullPointerException) but you need to be aware that "a field with a value of null" isn't the same as "a field which hasn't been explicitly assigned a value". Null is a perfectly valid variable value (for non-primitive variables, of course). Indeed, you may even want to change the above code to:

if (box != null) {
    box.removeFromCanvas();
    // Forget about the box - we don't want to try to remove it again
    box = null;
}

The difference is also visible for local variables, which can't be read before they've been "definitely assigned" - but one of the values which they can be definitely assigned is null (for reference type variables):

// Won't compile
String x;
System.out.println(x);

// Will compile, prints null
String y = null;
System.out.println(y);

You cannot set height and width for elements with display:inline;. Use display:inline-block; instead.

From the CSS2 spec:

10.6.1 Inline, non-replaced elements

The height property does not apply. The height of the content area should be based on the font, but this specification does not specify how. A UA may, e.g., use the em-box or the maximum ascender and descender of the font. (The latter would ensure that glyphs with parts above or below the em-box still fall within the content area, but leads to differently sized boxes for different fonts; the former would ensure authors can control background styling relative to the 'line-height', but leads to glyphs painting outside their content area.)

EDIT — You're also missing a ; terminator for the height property:

<div style="display:inline; height:20px width: 70px">My Text Here</div>
<!--                                  ^^ here                       -->

Working example: http://jsfiddle.net/FpqtJ/

check your casing, the name is typically stored in upper case

SELECT * FROM all_source WHERE name = 'DAILY_UPDATE' ORDER BY TYPE, LINE;

DESCRIBE FORMATTED my_table;

or

DESCRIBE FORMATTED my_table PARTITION (my_column='my_value');

Assuming that I have understood your scenario correctly, this is what I would call the right way to do this:

Start from a higher-level description of your database! You have employees, and employees can be "ce" employees and "sn" employees (whatever those are). In object-oriented terms, there is a class "employee", with two sub-classes called "ce employee" and "sn employee".

Then you translate this higher-level description to three tables: employees, employees_ce and employees_sn:

• employees(id, name)
• employees_ce(id, ce-specific stuff)
• employees_sn(id, sn-specific stuff)

Since all employees are employees (duh!), every employee will have a row in the employees table. "ce" employees also have a row in the employees_ce table, and "sn" employees also have a row in the employees_sn table. employees_ce.id is a foreign key to employees.id, just as employees_sn.id is.

To refer to an employee of any kind (ce or sn), refer to the employees table. That is, the foreign key you had trouble with should refer to that table!

Try this example for inset text shadow. Here's the HTML

<h1 class="inset-text-shadow">Inset text shadow trick</h1>

and the CSS

body {
    background: #f8f8f8;
}
h1 {
    font-family: Helvetica, Arial, sans-serif;
    font-weight: bold;
    font-size: 6em;
    line-height: 1em;
}
.inset-text-shadow {
    /* Shadows are visible under slightly transparent text color */
    color: rgba(0,0,0,0.6);
    text-shadow: 2px 8px 6px rgba(0,0,0,0.2), 0px -5px 35px rgba(255,255,255,0.3);

}

You can kill the process which is running the container.

With this command you can list the processes related with the docker container:

ps -aux | grep $(docker ps -a | grep container-name | awk '{print $1}')

Now you have the process ids to kill with kill or kill -9.

Here's a workaround.

Make a template subclass B of A. Do the template-argument-independent part of the construction in A's constructor. Do the template-argument-dependent part in B's constructor.

ASCII encoding is 7-bit, but in practice, characters encoded in ASCII are not stored in groups of 7 bits. Instead, one ASCII is stored in a byte, with the MSB usually set to 0 (yes, it's wasted in ASCII).

You can verify this by inputting a string in the ASCII character set in a text editor, setting the encoding to ASCII, and viewing the binary/hex:

Aside: the use of (strictly) ASCII encoding is now uncommon, in favor of UTF-8 (which does not waste the MSB mentioned above - in fact, an MSB of 1 indicates the code point is encoded with more than 1 byte).

Create an abstract method, and have each of your enumeration values override it. Since you know the opposite while you're creating it, there's no need to dynamically generate or create it.

It doesn't read nicely though; perhaps a switch would be more manageable?

public enum Direction {
    NORTH(1) {
        @Override
        public Direction getOppositeDirection() {
            return Direction.SOUTH;
        }
    },
    SOUTH(-1) {
        @Override
        public Direction getOppositeDirection() {
            return Direction.NORTH;
        }
    },
    EAST(-2) {
        @Override
        public Direction getOppositeDirection() {
            return Direction.WEST;
        }
    },
    WEST(2) {
        @Override
        public Direction getOppositeDirection() {
            return Direction.EAST;
        }
    };

    Direction(int code){
        this.code=code;
    }
    protected int code;

    public int getCode() {
        return this.code;
    }

    public abstract Direction getOppositeDirection();
}

As far as I know, if an exception is not caught by your script, it will be interrupted.

Try this- Close the project then open it. It links with svn automatically,if project was checked out from valid svn path.

Hash's key? method tells you whether a given key is present or not.

session.key?("user")

If you are sending alphanumeric data try changing

'Content-Type': 'multipart/form-data'

to

'Content-Type': 'application/x-www-form-urlencoded'

If you are sending non-alphanumeric data try to remove 'Content-Type' at all.

If it still does not work, consider trying request-promise (at least to test whether it is really axios problem or not)

The reason for this problem is the cache files in localhost. According to that I've tried several things as follows to clear the cache on my project, but every time I've failed.

• Tried to clear cahe commands by changing web.php file (with artisan codes)
• Tried to clear cache by connecting SSH (via PUTTY)
• Tried to host my project in Sub domain within create a new Public directory

So I've found a solution for this problem after each and every above steps failed and it worked for me perfectly. I deleted the cache.php file in host_route/bootstrap/cache directory.

I think this answer will help your problem.

MySQL will assume the part before the equals references the columns named in the INSERT INTO clause, and the second part references the SELECT columns.

INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, 
                inact, inadur, inadist, 
                smlct, smldur, smldist, 
                larct, lardur, lardist, 
                emptyct, emptydur)
SELECT id, uid, t.location, t.animal, t.starttime, t.endtime, t.entct, 
       t.inact, t.inadur, t.inadist, 
       t.smlct, t.smldur, t.smldist, 
       t.larct, t.lardur, t.lardist, 
       t.emptyct, t.emptydur 
FROM tmp t WHERE uid=x
ON DUPLICATE KEY UPDATE entct=t.entct, inact=t.inact, ...

Short answer:

ALTER SCHEMA new_schema TRANSFER old_schema.table_name

I can confirm that the data in the table remains intact, which is probably quite important :)

Long answer as per MSDN docs,

ALTER SCHEMA schema_name 
   TRANSFER [ Object | Type | XML Schema Collection ] securable_name [;]

If it's a table (or anything besides a Type or XML Schema collection), you can leave out the word Object since that's the default.

It is now much easier to do this in Eclipse now. Just right click on the package that will contain your new activity. New -> Other -> (Under Android tab) Android Activity.

And that's all. Your new activity is automatically added to the manifest file as well.

There is no such thing as an interpreted language. Whether an interpreter or a compiler is used is purely a trait of the implementation and has absolutely nothing whatsoever to do with the language.

Every language can be implemented by either an interpreter or a compiler. The vast majority of languages have at least one implementation of each type. (For example, there are interpreters for C and C++ and there are compilers for JavaScript, PHP, Perl, Python and Ruby.) Besides, the majority of modern language implementations actually combine both an interpreter and a compiler (or even multiple compilers).

A language is just a set of abstract mathematical rules. An interpreter is one of several concrete implementation strategies for a language. Those two live on completely different abstraction levels. If English were a typed language, the term "interpreted language" would be a type error. The statement "Python is an interpreted language" is not just false (because being false would imply that the statement even makes sense, even if it is wrong), it just plain doesn't make sense, because a language can never be defined as "interpreted."

In particular, if you look at the currently existing Python implementations, these are the implementation strategies they are using:

• IronPython: compiles to DLR trees which the DLR then compiles to CIL bytecode. What happens to the CIL bytecode depends upon which CLI VES you are running on, but Microsoft .NET, GNU Portable.NET and Novell Mono will eventually compile it to native machine code.
• Jython: interprets Python sourcecode until it identifies the hot code paths, which it then compiles to JVML bytecode. What happens to the JVML bytecode depends upon which JVM you are running on. Maxine will directly compile it to un-optimized native code until it identifies the hot code paths, which it then recompiles to optimized native code. HotSpot will first interpret the JVML bytecode and then eventually compile the hot code paths to optimized machine code.
• PyPy: compiles to PyPy bytecode, which then gets interpreted by the PyPy VM until it identifies the hot code paths which it then compiles into native code, JVML bytecode or CIL bytecode depending on which platform you are running on.
• CPython: compiles to CPython bytecode which it then interprets.
• Stackless Python: compiles to CPython bytecode which it then interprets.
• Unladen Swallow: compiles to CPython bytecode which it then interprets until it identifies the hot code paths which it then compiles to LLVM IR which the LLVM compiler then compiles to native machine code.
• Cython: compiles Python code to portable C code, which is then compiled with a standard C compiler
• Nuitka: compiles Python code to machine-dependent C++ code, which is then compiled with a standard C compiler

You might notice that every single one of the implementations in that list (plus some others I didn't mention, like tinypy, Shedskin or Psyco) has a compiler. In fact, as far as I know, there is currently no Python implementation which is purely interpreted, there is no such implementation planned and there never has been such an implementation.

Not only does the term "interpreted language" not make sense, even if you interpret it as meaning "language with interpreted implementation", it is clearly not true. Whoever told you that, obviously doesn't know what he is talking about.

In particular, the .pyc files you are seeing are cached bytecode files produced by CPython, Stackless Python or Unladen Swallow.

You can do it. this is a easy way.

Anytime you're changing the headers of an HttpWebRequest, you need to use the appropriate properties on the object itself, if they exist. If you have a plain WebRequest, be sure to cast it to an HttpWebRequest first. Then Referrer in your case can be accessed via ((HttpWebRequest)request).Referrer, so you don't need to modify the header directly - just set the property to the right value. ContentLength, ContentType, UserAgent, etc, all need to be set this way.

IMHO, this is a shortcoming on MS part...setting the headers via Headers.Add() should automatically call the appropriate property behind the scenes, if that's what they want to do.

Pretty easy:

 public void PrintSql_Array()
    {
        int[] numbers = new int[4];
        string[] names = new string[4];
        string[] secondNames = new string[4];
        int[] ages = new int[4];

        int cont = 0;

        string cs = @"Server=ADMIN\SQLEXPRESS; Database=dbYourBase; User id=sa; password=youpass";
        using (SqlConnection con = new SqlConnection(cs))
        {
            using (SqlCommand cmd = new SqlCommand())
            {
                cmd.Connection = con;
                cmd.CommandType = CommandType.Text;
                cmd.CommandText = "SELECT * FROM tbl_Datos";
                con.Open();

                SqlDataAdapter da = new SqlDataAdapter(cmd);
                DataTable dt = new DataTable();
                da.Fill(dt);

                foreach (DataRow row in dt.Rows)
                {
                    numbers[cont] = row.Field<int>(0);
                    names[cont] = row.Field<string>(1);
                    secondNames[cont] = row.Field<string>(2);
                    ages[cont] = row.Field<int>(3);

                    cont++;
                }

                for (int i = 0; i < numbers.Length; i++)
                {
                    Console.WriteLine("{0} | {1} {2} {3}", numbers[i], names[i], secondNames[i], ages[i]);
                }

                con.Close();
            }
        }
    }

The short answer for lazy people like me:

type Overrided = Omit<YourInterface, 'overrideField'> & { overrideField: <type> }; 

The .NET framework uses banker's rounding in Math.Round by default. You should use this overload:

Math.Round(0.5d, MidpointRounding.AwayFromZero)  //1
Math.Round(0.4d, MidpointRounding.AwayFromZero)  //0

No. It is not possible to share the same port at a particular instant. But you can make your application such a way that it will make the port access at different instant.

Not sure if this is what you were looking for, but this worked for me:

$query = query("DESC YourTable");  
$col_names = array_column($query, 'Field');

That returns a simple array of the column names / variable names in your table or array as strings, which is what I needed to dynamically build MySQL queries. My frustration was that I simply don't know how to index arrays in PHP very well, so I wasn't sure what to do with the results from DESC or SHOW. Hope my answer is helpful to beginners like myself!

To check result: print_r($col_names);

I too got the same problem
I downloaded get-pip.py from https://bootstrap.pypa.io/get-pip.py

and then ran python2.7 get-pip.py for installing pip2.7

and then ran the pip install command with python2.7 as follows

For Ubuntu/Linux:

python2.7 -m pip install https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.5.0-cp27-none-linux_x86_64.whl

For Mac OS X:

python2.7 -m pip install https://storage.googleapis.com/tensorflow/mac/tensorflow-0.5.0-py2-none-any.whl

this should work just fine as it did for me :)

I followed these instructions from here

Have you noticed that in the code you posted, condition2 is never set to False? This way, your loop body is never executed.

Also, note that in Python, not condition is preferred to condition == False; likewise, condition is preferred to condition == True.

Override ui-page class in your css:

.ui-page {
    background: url("image.gif");
    background-repeat: repeat;
}

Try something like this:

SELECT 
* 
FROM
(SELECT ks, COUNT(*) AS '# Tasks' FROM Table GROUP BY ks) t1 
INNER JOIN
(SELECT ks, COUNT(*) AS '# Late' FROM Table WHERE Age > Palt GROUP BY ks) t2
ON t1.ks = t2.ks

I don't know of any good libraries for this, but whatever you do, make sure that you err in the direction of letting stuff through. I've dealt with systems that wouldn't allow me to use "mpassell" as a username, because it contains "ass" as a substring. That's a great way to alienate users!

Dispatcher Controller are displayed in the figure all the incoming request is in intercepted by the dispatcher servlet that works as front controller. The dispatcher servlet gets an entry to handler mapping from the XML file and forwords the request to the Controller.

If you need to frequently perform in-cell edits on SQL databases, HeidiSQL works a treat, couldn't be simpler to use, and is free / open source (donations accepted).

Some people say C doesn't have namespaces but that is not technically correct. It has three:

1. Tags (enum, union, and struct)
2. Labels
3. (everything else)

typedef enum { } XYZ; declares an anonymous enumeration and imports it into the global namespace with the name XYZ.

typedef enum ABC { } XYZ; declares an enum named ABC in the tag namespace, then imports it into the global namespace as XYZ.

Some people don't want to bother with the separate namespaces so they typedef everything. Others never typedef because they want the namespacing.

Get is supposed to return, one and exactly one record, to fix this use filter(), and then take first element of the queryset returned to get the object you were expecting from get, also it would be useful to check if atleast one record is returned before taking out the first element to avoid IndexError

You can set the figure size if you explicitly create the figure with

plt.figure(figsize=(3,4))

You need to set figure size before calling plt.plot() To change the format of the saved figure just change the extension in the file name. However, I don't know if any of matplotlib backends support tiff

To select the sibling, you'd need something like:

$(this).next();

So, Shog9's comment is not correct. First of all, you'd need to name the variable "clicked" outside of the div click function, otherwise, it is lost after the click occurs.

var clicked;

$("div a").click(function(){
   clicked = $(this).next();
   // Do what you need to do to the newly defined click here
});

// But you can also access the "clicked" element here

Given the update to the original question, it seems like there is trouble with the context ("this") while passing event handlers. The basics are explained e.g. here http://www.w3schools.com/js/js_function_invocation.asp

A simple working version of your example could read

var doClick = function(event, additionalParameter){
    // do stuff with event and this being the triggering event and caller
}

element.addEventListener('click', function(event)
{
  var additionalParameter = ...;
  doClick.call(this, event, additionalParameter );
}, false);

Here's an example geared toward watching input files that write no more than one line per second but usually a lot less. The goal is to append the last line (most recent write) to the specified output file. I've copied this from one of my projects and just deleted all the irrelevant lines. You'll have to fill in or change the missing symbols.

from PyQt5.QtCore import QFileSystemWatcher, QSettings, QThread
from ui_main_window import Ui_MainWindow   # Qt Creator gen'd 

class MainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        QMainWindow.__init__(self, parent)
        Ui_MainWindow.__init__(self)
        self._fileWatcher = QFileSystemWatcher()
        self._fileWatcher.fileChanged.connect(self.fileChanged)

    def fileChanged(self, filepath):
        QThread.msleep(300)    # Reqd on some machines, give chance for write to complete
        # ^^ About to test this, may need more sophisticated solution
        with open(filepath) as file:
            lastLine = list(file)[-1]
        destPath = self._filemap[filepath]['dest file']
        with open(destPath, 'a') as out_file:               # a= append
            out_file.writelines([lastLine])

Of course, the encompassing QMainWindow class is not strictly required, ie. you can use QFileSystemWatcher alone.

Made some modification on Andrew's solution and update the code to Swift 3:

This code now use UITextView as self and able to inherit its original font, font size and text color

Note: toHexString() is extension from here

extension UITextView {
    func setAttributedStringFromHTML(_ htmlCode: String, completionBlock: @escaping (NSAttributedString?) ->()) {
        let inputText = "\(htmlCode)<style>body { font-family: '\((self.font?.fontName)!)'; font-size:\((self.font?.pointSize)!)px; color: \((self.textColor)!.toHexString()); }</style>"

        guard let data = inputText.data(using: String.Encoding.utf16) else {
            print("Unable to decode data from html string: \(self)")
            return completionBlock(nil)
        }

        DispatchQueue.main.async {
            if let attributedString = try? NSAttributedString(data: data, options: [NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType], documentAttributes: nil) {
                self.attributedText = attributedString
                completionBlock(attributedString)
            } else {
                print("Unable to create attributed string from html string: \(self)")
                completionBlock(nil)
            }
        }
    }
}

Example usage:

mainTextView.setAttributedStringFromHTML("<i>Hello world!</i>") { _ in }

use this

SELECT SUBSTRING_INDEX(SUBSTRING_INDEX( `membername` , ' ', 2 ),' ',1) AS b, 
SUBSTRING_INDEX(SUBSTRING_INDEX( `membername` , ' ', -1 ),' ',2) AS c FROM `users` WHERE `userid`='1'

reload() is supposed to accept an argument which tells it to do a hard reload, ie, ignoring the cache:

location.reload(true);

I can't vouch for its reliability, you may want to investigate this further.

Using moment.js, you can use keepOffset parameter of toISOString:

toISOString(keepOffset?: boolean): string;

moment().toISOString(true)

On Gitlab, markdown supports this : [[_TOC_]]

Another great example of when static attributes and operations are used when you want to apply the Singleton design pattern. In a nutshell, the Singleton design pattern ensures that one and only one object of a particular class is ever constructeed during the lifetime of your system. to ensure that only one object is ever constructed, typical implemenations of the Singleton pattern keep an internal static reference to the single allowed object instance, and access to that instance is controlled using a static operation

Deleting a function is a C++11 feature:

The common idiom of "prohibiting copying" can now be expressed directly:

class X {
    // ...
    X& operator=(const X&) = delete;  // Disallow copying
    X(const X&) = delete;
};

[...]

The "delete" mechanism can be used for any function. For example, we can eliminate an undesired conversion like this:

struct Z {
    // ...

    Z(long long);     // can initialize with an long long         
    Z(long) = delete; // but not anything less
};

Don't use NULL, C++ allows you to use the unadorned 0 instead:

previous = 0;
next = 0;

And, as at C++11, you generally shouldn't be using either NULL or 0 since it provides you with nullptr of type std::nullptr_t, which is better suited to the task.

If you write like this in Button tag in xml file : android:onClick="setLogin" then

Do like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<Button
    android:id="@+id/button1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btn"
    android:onClick="onClickBtn" />

</LinearLayout>

and in Code part:

public class StartUpActivity extends Activity 
{
    public void onCreate(Bundle savedInstanceState) 
    {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);    
    }

    public void onClickBtn(View v)
    {
        Toast.makeText(this, "Clicked on Button", Toast.LENGTH_LONG).show();
    } 
}

and no need all this:

 Button button = (Button) findViewById(R.id.button1);
 button.setOnClickListener(new OnClickListener() {

    public void onClick(View v) {
        // TODO Auto-generated method stub

    }
 });

Check it once;

For those who could not get DATEADD to work, try this instead: ( NOW( ) - INTERVAL 1 MONTH )

Before you begin, if you are uncomfortable with a command line, you can do all the following steps using SourceTree, GitExtension, GitHub Desktop, or your favorite tool.

To solve the issue, you might have two scenarios:

1) Fix only remote repository branch which is behind commit

Example: Both branches are on the remote side

ahead === Master branch

behind === Develop branch

Solution:

1. Clone the repository to the local workspace: this will give you the Master branch which is ahead with commit

   git clone repositoryUrl
   

2. Create a branch with Develop name and checkout to that branch locally

   git checkout -b DevelopBranchName // this command creates and checkout the branch
   

3. Pull from the remote Develop branch. Conflict might occur. if so, fix the conflict and commit the changes.

    git pull origin DevelopBranchName
   

4. Merge the local Develop branch with the remote Develop branch

     git merge origin develop
   

5. Push the merged branch to the remote Develop branch

     git push origin develop
   

2) Local Master branch is behind the remote Master branch

This means every locally created branch is behind.

Before preceding, you have to commit or stash all the changes you made on the branch that is behind commits.

Solution:

1. Checkout your local Master branch

   git checkout master
   

2. Pull from remote Master branch

   git pull origin master
   

Now your local Master is in sync with the remote Branch but other local branches, that branched from the local Master branch, are not in sync with your local Master branch because of the above command. To fix that:

1. Checkout the branch that is behind your local Master branch

   git checkout BranchNameBehindCommit
   

2. Merge with the local Master branch

   git merge master  // Now your branch is in sync with local Master branch
   

If this branch is on the remote repository, you have to push your changes

    git push origin branchBehindCommit

Xcode 9 introduced new tricks with XCTWaiter

Test case waits explicitly

wait(for: [documentExpectation], timeout: 10)

Waiter instance delegates to test

XCTWaiter(delegate: self).wait(for: [documentExpectation], timeout: 10)

Waiter class returns result

let result = XCTWaiter.wait(for: [documentExpectation], timeout: 10)
switch(result) {
case .completed:
    //all expectations were fulfilled before timeout!
case .timedOut:
    //timed out before all of its expectations were fulfilled
case .incorrectOrder:
    //expectations were not fulfilled in the required order
case .invertedFulfillment:
    //an inverted expectation was fulfilled
case .interrupted:
    //waiter was interrupted before completed or timedOut
}

sample usage

Before Xcode 9

Objective C

- (void)waitForElementToAppear:(XCUIElement *)element withTimeout:(NSTimeInterval)timeout
{
    NSUInteger line = __LINE__;
    NSString *file = [NSString stringWithUTF8String:__FILE__];
    NSPredicate *existsPredicate = [NSPredicate predicateWithFormat:@"exists == true"];

    [self expectationForPredicate:existsPredicate evaluatedWithObject:element handler:nil];

    [self waitForExpectationsWithTimeout:timeout handler:^(NSError * _Nullable error) {
        if (error != nil) {
            NSString *message = [NSString stringWithFormat:@"Failed to find %@ after %f seconds",element,timeout];
            [self recordFailureWithDescription:message inFile:file atLine:line expected:YES];
        }
    }];
}

USAGE

XCUIElement *element = app.staticTexts["Name of your element"];
[self waitForElementToAppear:element withTimeout:5];

Swift

func waitForElementToAppear(element: XCUIElement, timeout: NSTimeInterval = 5,  file: String = #file, line: UInt = #line) {
        let existsPredicate = NSPredicate(format: "exists == true")

        expectationForPredicate(existsPredicate,
                evaluatedWithObject: element, handler: nil)

        waitForExpectationsWithTimeout(timeout) { (error) -> Void in
            if (error != nil) {
                let message = "Failed to find \(element) after \(timeout) seconds."
                self.recordFailureWithDescription(message, inFile: file, atLine: line, expected: true)
            }
        }
    }

USAGE

let element = app.staticTexts["Name of your element"]
self.waitForElementToAppear(element)

or

let element = app.staticTexts["Name of your element"]
self.waitForElementToAppear(element, timeout: 10)

I periodically have this problem as well in Visual Studio 2010. Closing Visual Studio, deleting the bin and obj directories, and re-launching will fix it for one build. Then the problem returns. I have tried every other answer on this thread and none worked for me. The only thing that resolves this permanently for me is to go to the project settings and turn off "Enable the Visual Studio hosting process", build, turn it back on, and build again.

you can also add inline css for adding image as a background as per below example

<div class="item active" style="background-image: url(../../foo.png);">

brew install --devel protobuf

If it tells you "protobuf-2.6.1 already installed": 1. brew uninstall --devel protobuf 2. brew link libtool 3. brew install --devel protobuf

Here is one simple PHP Script which gets exchange rate between GBP and USD

<?php
$amount = urlencode("1");
$from_GBP0 = urlencode("GBP");
$to_usd= urlencode("USD");
$Dallor = "hl=en&q=$amount$from_GBP0%3D%3F$to_usd";
$US_Rate = file_get_contents("http://google.com/ig/calculator?".$Dallor);
$US_data = explode('"', $US_Rate);
$US_data = explode(' ', $US_data['3']);
$var_USD = $US_data['0'];
echo $to_usd;
echo $var_USD;
echo '<br/>'; 
?>

Google currency rates are not accurate google itself says ==> Google cannot guarantee the accuracy of the exchange rates used by the calculator. You should confirm current rates before making any transactions that could be affected by changes in the exchange rates. Foreign currency rates provided by Citibank N.A. are displayed under licence. Rates are for information purposes only and are subject to change without notice. Rates for actual transactions may vary and Citibank is not offering to enter into any transaction at any rate displayed.

You can use .change() function too

E.g.:

$('form input[type=checkbox]').change(function() { console.log('hello') });

Would be safer to do this.

@{ Response.Redirect("~/Account/LogIn?returnUrl=Products");}

So the controller for that action runs as well, to populate any model the view needs.

Source
Redirect from a view to another view

Although as @Satpal mentioned, I do recommend you do the redirecting on your controller.

Elisabeth you can change viewport content dynamically by adding the "id" property to the metatag:

<meta name="viewport" id="view" content="user-scalable=yes, width=device-width minimum-scale=1, maximum-scale=1" />

Then you just can call by javascript:

document.getElementById("view").setAttribute('content','user-scalable=yes, width=device-width, minimum-scale=1, maximum-scale=10');

Despite the danger of stating the obvious: With a unit test you want to test the correct behaviour of the object - and this is defined in terms of its public interface. You are not interested in how the object accomplishes this task - this is an implementation detail and not visible to the outside. This is one of the things why OO was invented: That implementation details are hidden. So there is no point in testing private members. You said you need 100% coverage. If there is a piece of code that cannot be tested by using the public interface of the object, then this piece of code is actually never called and hence not testable. Remove it.

To get insight on every function calls recursively, do:

%load_ext snakeviz
%%snakeviz

It just takes those 2 lines of code in a Jupyter notebook, and it generates a nice interactive diagram. For example:

Here is the code. Again, the 2 lines starting with % are the only extra lines of code needed to use snakeviz:

# !pip install snakeviz
%load_ext snakeviz
import glob
import hashlib

%%snakeviz

files = glob.glob('*.txt')
def print_files_hashed(files):
    for file in files:
        with open(file) as f:
            print(hashlib.md5(f.read().encode('utf-8')).hexdigest())
print_files_hashed(files)

It also seems possible to run snakeviz outside notebooks. More info on the snakeviz website.

There's a bit more to it than just local vs global. Global variables created with var are different than those created without. Consider this:

var foo = 1; // declared properly
bar = 2; // implied global
window.baz = 3; // global via window object

Based on the answers so far, these global variables, foo, bar, and baz are all equivalent. This is not the case. Global variables made with var are (correctly) assigned the internal [[DontDelete]] property, such that they cannot be deleted.

delete foo; // false
delete bar; // true
delete baz; // true

foo; // 1
bar; // ReferenceError
baz; // ReferenceError

This is why you should always use var, even for global variables.

Delete all documents from a collection in cmd:

cd C:\Program Files\MongoDB\Server\4.2\bin

db.yourcollection.remove( { } )

It took me some time to resolve this.

• Updated SDK Build-Tool [Didn't help]
• Updated CMake [Didn't help]
• Updated Android SDK Platform-Tools [Didn't help]
• Updated Android SDK Tools [Didn't help]
• Updated NDK [Problem solved]

There was a reason, I didn't want to update NDK. When all else failed, I updated NDK and that did the trick.

I am planning to use !important for a third-party widget meant to be embedded in a large number of websites out of my control.

I reached the conclusion !important is the only solution to protect the widget's stylesheet from the host stylesheet (apart from iframe and inline styles, which are equally bad). For instance, WordPress uses:

#left-area ul {
    list-style-type: disc;
    padding: 0 0 23px 16px;
    line-height: 26px;
}

This rule threathens to override any UL in my widget because id's have strong specificity. In that case, systematic use of !important seems to be one of the few solutions.
