Old post, but I thought I would share my solution because there aren't many solutions out there for this issue.

If you're running an old Windows Server 2003 machine, you likely need to install a hotfix (KB938397).

This problem occurs because the Cryptography API 2 (CAPI2) in Windows Server 2003 does not support the SHA2 family of hashing algorithms. CAPI2 is the part of the Cryptography API that handles certificates.

https://support.microsoft.com/en-us/kb/938397

For whatever reason, Microsoft wants to email you this hotfix instead of allowing you to download directly. Here's a direct link to the hotfix from the email:

Faced the same issue in my spring boot application even though I had my package specific scans enabled like

@SpringBootApplication(scanBasePackages={"com.*"})

But, the issue was resolved by providing @ComponentScan({"com.*"}) in my Application class.

// will return the host name and port
var host = window.location.host; 

or possibly

var host = window.location.protocol + "//" + window.location.host;

or if you like concatenation

var protocol = location.protocol;
var slashes = protocol.concat("//");
var host = slashes.concat(window.location.host);

// or as you probably should do
var host = location.protocol.concat("//").concat(window.location.host);

// the above is the same as origin, e.g. "https://stackoverflow.com"
var host = window.location.origin;

If you have or expect custom ports use window.location.host instead of window.location.hostname

If you are 100% sure $message contain ISO-8859-1 you can use utf8_encode as David says. Otherwise use mb_detect_encoding and mb_convert_encoding on $message.

Also take note that

$mail -> charSet = "UTF-8"; 

Should be replaced by:

$mail->CharSet = 'UTF-8';

And placed after the instantiation of the class (after the new). The properties are case sensitive! See the PHPMailer doc fot the list & exact spelling.

Also the default encoding of PHPMailer is 8bit which can be problematic with UTF-8 data. To fix this you can do:

$mail->Encoding = 'base64';

Take note that 'quoted-printable' would probably work too in these cases (and maybe even 'binary'). For more details you can read RFC1341 - Content-Transfer-Encoding Header Field.

Have you asked your provider to investigate? I assume this is not a dedicated server,

On the face of it, this seems like a security exception and somone is trying to exploit it / or there is a process running at a set time which is causing this, can you think of anything that runs on the server every 2 days? Logging tools?

SIGTERM is the signal sent to a process to request its termination. The symbolic constant for SIGTERM is defined in the header file signal.h. Symbolic signal names are used because signal numbers can vary across platforms, however on the vast majority of systems, SIGTERM is signal #15.

If you want to include into your code and not use the IntentIntegrator that the ZXing library recommend, you can use some of these ports:

• http://code.google.com/p/android-zxinglib/

• http://code.google.com/p/android-quick-response-code/

I use the first, and it works perfectly! It has a sample project to try it on.

The correct way would be to use "--" to stop processing arguments, as already mentioned. This is due to the usage of getopt_long (GNU C-function from getopt.h) in the source of the tool.

This is why you notice the same phenomena on other command-line tools; since most of them are GNU tools, and use this call,they exhibit the same behavior.

As a side note - getopt_long is what gives us the cool choice between -rlo and --really_long_option and the combination of arguments in the interpreter.

Django is designed to be easely used to deliver web pages. If you are not confortable with this perhaps you should use another solution.

I'm writting the root or common operations on the model (to have the same interface) and the others on the controller of the model. If I need an operation from other model I import its controller.

This approach it's enough for me and the complexity of my applications.

Hedde's response is an example that shows the flexibility of django and python itself.

Very interesting question anyway!

You can configure the ObjectMapper as a bean in your Spring xml file. What holds a reference to the ObjectMapper is the MappingJacksonJsonView class. You then need to attach the view to a ViewResolver.

Something like this should work:

<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
      <property name="mediaTypes">
      <map>
        <entry key="json" value="application/json" />
        <entry key="html" value="text/html" />
      </map>
    </property>
    <property name="viewResolvers">
      <list>
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
          <property name="prefix" value="/WEB-INF/jsp/" />
          <property name="suffix" value=".jsp" />
        </bean>
      </list>
    </property>
    <property name="defaultViews">
      <list>
        <bean class="org.springframework.web.servlet.view.json.MappingJacksonJsonView">
          <property name="prefixJson" value="false" />
          <property name="objectMapper" value="customObjectMapper" />
        </bean>
      </list>
    </property>
  </bean>

Where customObjectMapper is defined elsewhere in the xml file. Note that you can directly set Spring property values with the Enums Jackson defines; see this question.

Also, ContentNegotiatingViewResolver probably isn't required, it's just the code I am using in an existing project.

Add this line in style of v21 if you use two style.

  <item name="android:statusBarColor">#43434f</item>

If you can't use JodaTime, you can do the following:

Calendar startCalendar = new GregorianCalendar();
startCalendar.setTime(startDate);
Calendar endCalendar = new GregorianCalendar();
endCalendar.setTime(endDate);

int diffYear = endCalendar.get(Calendar.YEAR) - startCalendar.get(Calendar.YEAR);
int diffMonth = diffYear * 12 + endCalendar.get(Calendar.MONTH) - startCalendar.get(Calendar.MONTH);

Note that if your dates are 2013-01-31 and 2013-02-01, you get a distance of 1 month this way, which may or may not be what you want.

There is an easier solution to this problem.

You just need to add a t to the mode so it becomes wt. This causes Python to open the file as a text file and not binary. Then everything will just work.

The complete program becomes this:

plaintext = input("Please enter the text you want to compress")
filename = input("Please enter the desired filename")
with gzip.open(filename + ".gz", "wt") as outfile:
    outfile.write(plaintext)

PHP's preg_replace example:

$str = "motttherbb fffaaattther";
$str = preg_replace("/([a-z])\\1/", "", $str);
echo $str;

Here [a-z] hits the character, () then allows it to be used with \\1 backreference which tries to match another same character (note this is targetting 2 consecutive characters already), thus:

mother father

If you did:

$str = preg_replace("/([a-z])\\1{2}/", "", $str);

that would be erasing 3 consecutive repeated characters, outputting:

moherbb her

Adding to assylias's answer - assylias shows us D.ITEMS is a method that returns an array. Knowing that, we don't need the variant array a(i) [See caveat below]. We just need to use the proper array syntax.

For i = 0 To d.Count - 1
    s = d.Items()(i)
    Debug.Print s
Next i()

KEYS works the same way

For i = 0 To d.Count - 1
    Debug.Print d.Keys()(i), d.Items()(i)
Next i

This syntax is also useful for the SPLIT function which may help make this clearer. SPLIT also returns an array with lower bounds at 0. Thus, the following prints "C".

Debug.Print Split("A,B,C,D", ",")(2)

SPLIT is a function. Its parameters are in the first set of parentheses. Methods and Functions always use the first set of parentheses for parameters, even if no parameters are needed. In the example SPLIT returns the array {"A","B","C","D"}. Since it returns an array we can use a second set of parentheses to identify an element within the returned array just as we would any array.

Caveat: This shorter syntax may not be as efficient as using the variant array a() when iterating through the entire dictionary since the shorter syntax invokes the dictionary's Items method with each iteration. The shorter syntax is best for plucking a single item by number from a dictionary.

select a.orgName,b.duplicate, a.id
from organizations a
inner join (
    SELECT orgName, COUNT(*) AS duplicate
    FROM organizations
    GROUP BY orgName
    HAVING COUNT(*) > 1
) b on o.orgName = oc.orgName
group by a.orgName,a.id

If you are using IIS 7.5 or later you can generate the machine key from IIS and save it directly to your web.config, within the web farm you then just copy the new web.config to each server.

1. Open IIS manager.
2. If you need to generate and save the MachineKey for all your applications select the server name in the left pane, in that case you will be modifying the root web.config file (which is placed in the .NET framework folder). If your intention is to create MachineKey for a specific web site/application then select the web site / application from the left pane. In that case you will be modifying the web.config file of your application.
3. Double-click the Machine Key icon in ASP.NET settings in the middle pane:
4. MachineKey section will be read from your configuration file and be shown in the UI. If you did not configure a specific MachineKey and it is generated automatically you will see the following options:
5. Now you can click Generate Keys on the right pane to generate random MachineKeys. When you click Apply, all settings will be saved in the web.config file.

Full Details can be seen @ Easiest way to generate MachineKey – Tips and tricks: ASP.NET, IIS and .NET development…

You can do it like this:

var mongoose = require('mongoose');
var _id = mongoose.mongo.BSONPure.ObjectID.fromHexString("4eb6e7e7e9b7f4194e000001");

EDIT: New standard has fromHexString rather than fromString

As stated in the above answers, it's always a good practice to initialize the variables, but if you have something which you don't know what value should it takes, and you want to leave it uninitialized so you have to make sure that you are updating it before using it.

For example: Assume we have double _bmi; and you don't know what value should it takes, so you can leave it as it is, but before using it, you have to update its value first like calling a function that calculating BMI like follows:

String calculateBMI (){
_bmi = weight / pow( height/100, 2);
return _bmi.toStringAsFixed(1);}

or whatever, what I mean is, you can leave the variable as it is, but before using it make sure you have initialized it using whatever the method you are using.

Very good question indeed. I just tried for myself.

public class IsInstanceOfTest {

    public static void main(final String[] args) {

        String s;

        s = "";

        System.out.println((s instanceof String));
        System.out.println(String.class.isInstance(s));

        s = null;

        System.out.println((s instanceof String));
        System.out.println(String.class.isInstance(s));
    }
}

Prints

true
true
false
false

JLS / 15.20.2. Type Comparison Operator instanceof

At run time, the result of the instanceof operator is true if the value of the RelationalExpression is not null and the reference could be cast to the ReferenceType without raising a ClassCastException. Otherwise the result is false.

API / Class#isInstance(Object)

If this Class object represents an interface, this method returns true if the class or any superclass of the specified Object argument implements this interface; it returns false otherwise. If this Class object represents a primitive type, this method returns false.

The ceil (ceiling) function:

import math
print(math.ceil(4.2))

Use the ? symbol (encoded as ⚲ or ⚲), and rotate it to achieve the desired effect:

<div style="-webkit-transform: rotate(45deg); 
               -moz-transform: rotate(45deg); 
                 -o-transform: rotate(45deg);
                    transform: rotate(45deg);">
    &#9906;
</div>

It rotates a symbol :)

I solved a similar problem by enveloping all css instructions in a php echo and then saving it as a php file (ofcourse starting and ending the file with the php tags), and then included the php file. This was a necessity as a redirect followed (header ("somefilename.php")) and no html code is allowed before a redirect.

I made a new checkout from the same project to a different location then copied the .svn folder from it and replaced with my old .svn folder. After that called the svn update function and everything were synced properly up to date.

doc_val_check == "";   // == is equality check operator

should be

doc_val_check = "";    // = is assign operator. you need to set empty value

                       // so you need =

You can write you full code like this:

var doc_val_check = $.trim( $('#doc_title').val() ); // take value of text 
                                                     // field using .val()
    if (doc_val_check.length) {
        doc_val_check = ""; // this will not update your text field
    }

To update you text field with a "" you need to try

$('#doc_title').attr('value', doc_val_check); 
// or 
$('doc_title').val(doc_val_check);

But I think you don't need above process.

In short, just one line

$('#doc_title').val("");

Note

.val() use to set/ get value in text field. With parameter it acts as setter and without parameter acts as getter.

You can also hide a column using the col element https://developer.mozilla.org/en/docs/Web/HTML/Element/col

To hide the second column in a table:

<table>
  <col />
  <col style="visibility:collapse"/>
  <tr><td>visible</td><td>hidden</td></tr>
  <tr><td>visible</td><td>hidden</td></tr>

This has a lot of answers, but I feel the need to add this extended method. This seems a lot longer, but it is extremely useful if you're adding a NOT NULL field to a table with millions of rows in an active database.

ALTER TABLE {schemaName}.{tableName}
    ADD {columnName} {datatype} NULL
    CONSTRAINT {constraintName} DEFAULT {DefaultValue}

UPDATE {schemaName}.{tableName}
    SET {columnName} = {DefaultValue}
    WHERE {columName} IS NULL

ALTER TABLE {schemaName}.{tableName}
    ALTER COLUMN {columnName} {datatype} NOT NULL

What this will do is add the column as a nullable field and with the default value, update all fields to the default value (or you can assign more meaningful values), and finally it will change the column to be NOT NULL.

The reason for this is if you update a large scale table and add a new not null field it has to write to every single row and hereby will lock out the entire table as it adds the column and then writes all the values.

This method will add the nullable column which operates a lot faster by itself, then fills the data before setting the not null status.

I've found that doing the entire thing in one statement will lock out one of our more active tables for 4-8 minutes and quite often I have killed the process. This method each part usually takes only a few seconds and causes minimal locking.

Additionally, if you have a table in the area of billions of rows it may be worth batching the update like so:

WHILE 1=1
BEGIN
    UPDATE TOP (1000000) {schemaName}.{tableName}
        SET {columnName} = {DefaultValue}
        WHERE {columName} IS NULL

    IF @@ROWCOUNT < 1000000
        BREAK;
END

A stateful server keeps state between connections. A stateless server does not.

So, when you send a request to a stateful server, it may create some kind of connection object that tracks what information you request. When you send another request, that request operates on the state from the previous request. So you can send a request to "open" something. And then you can send a request to "close" it later. In-between the two requests, that thing is "open" on the server.

When you send a request to a stateless server, it does not create any objects that track information regarding your requests. If you "open" something on the server, the server retains no information at all that you have something open. A "close" operation would make no sense, since there would be nothing to close.

HTTP and NFS are stateless protocols. Each request stands on its own.

Sometimes cookies are used to add some state to a stateless protocol. In HTTP (web pages), the server sends you a cookie and then the browser holds the state, only to send it back to the server on a subsequent request.

SMB is a stateful protocol. A client can open a file on the server, and the server may deny other clients access to that file until the client closes it.

To just merge the arrays (without removing duplicates)

ES5 version use Array.concat:

var array1 = ["Vijendra", "Singh"];
var array2 = ["Singh", "Shakya"];

console.log(array1.concat(array2));

ES6 version use destructuring

const array1 = ["Vijendra","Singh"];
const array2 = ["Singh", "Shakya"];
const array3 = [...array1, ...array2];

Since there is no 'built in' way to remove duplicates (ECMA-262 actually has Array.forEach which would be great for this), we have to do it manually:

Array.prototype.unique = function() {
    var a = this.concat();
    for(var i=0; i<a.length; ++i) {
        for(var j=i+1; j<a.length; ++j) {
            if(a[i] === a[j])
                a.splice(j--, 1);
        }
    }

    return a;
};

Then, to use it:

var array1 = ["Vijendra","Singh"];
var array2 = ["Singh", "Shakya"];
// Merges both arrays and gets unique items
var array3 = array1.concat(array2).unique(); 

This will also preserve the order of the arrays (i.e, no sorting needed).

Since many people are annoyed about prototype augmentation of Array.prototype and for in loops, here is a less invasive way to use it:

function arrayUnique(array) {
    var a = array.concat();
    for(var i=0; i<a.length; ++i) {
        for(var j=i+1; j<a.length; ++j) {
            if(a[i] === a[j])
                a.splice(j--, 1);
        }
    }

    return a;
}

var array1 = ["Vijendra","Singh"];
var array2 = ["Singh", "Shakya"];
    // Merges both arrays and gets unique items
var array3 = arrayUnique(array1.concat(array2));

For those who are fortunate enough to work with browsers where ES5 is available, you can use Object.defineProperty like this:

Object.defineProperty(Array.prototype, 'unique', {
    enumerable: false,
    configurable: false,
    writable: false,
    value: function() {
        var a = this.concat();
        for(var i=0; i<a.length; ++i) {
            for(var j=i+1; j<a.length; ++j) {
                if(a[i] === a[j])
                    a.splice(j--, 1);
            }
        }

        return a;
    }
});

In the same vein as martineau's response, the best solution is often not to check. For example, the code

if x in d:
    foo = d[x]
else:
    foo = bar

is normally written

foo = d.get(x, bar)

which is shorter and more directly speaks to what you mean.

Another common case is something like

if x not in d:
    d[x] = []

d[x].append(foo)

which can be rewritten

d.setdefault(x, []).append(foo)

or rewritten even better by using a collections.defaultdict(list) for d and writing

d[x].append(foo)

toISOString() will return current UTC time only not the current local time. If you want to get the current local time in yyyy-MM-ddTHH:mm:ss.SSSZ format then you should get the current time using following two methods

Method 1:

document.write(new Date(new Date().toString().split('GMT')[0]+' UTC').toISOString());

Method 2:

document.write(new Date(new Date().getTime() - new Date().getTimezoneOffset() * 60000).toISOString());

You cannot append to an existing xlsx file with xlsxwriter.

There is a module called openpyxl which allows you to read and write to preexisting excel file, but I am sure that the method to do so involves reading from the excel file, storing all the information somehow (database or arrays), and then rewriting when you call workbook.close() which will then write all of the information to your xlsx file.

Similarly, you can use a method of your own to "append" to xlsx documents. I recently had to append to a xlsx file because I had a lot of different tests in which I had GPS data coming in to a main worksheet, and then I had to append a new sheet each time a test started as well. The only way I could get around this without openpyxl was to read the excel file with xlrd and then run through the rows and columns...

i.e.

cells = []
for row in range(sheet.nrows):
    cells.append([])
    for col in range(sheet.ncols):
        cells[row].append(workbook.cell(row, col).value)

You don't need arrays, though. For example, this works perfectly fine:

import xlrd
import xlsxwriter

from os.path import expanduser
home = expanduser("~")

# this writes test data to an excel file
wb = xlsxwriter.Workbook("{}/Desktop/test.xlsx".format(home))
sheet1 = wb.add_worksheet()
for row in range(10):
    for col in range(20):
        sheet1.write(row, col, "test ({}, {})".format(row, col))
wb.close()

# open the file for reading
wbRD = xlrd.open_workbook("{}/Desktop/test.xlsx".format(home))
sheets = wbRD.sheets()

# open the same file for writing (just don't write yet)
wb = xlsxwriter.Workbook("{}/Desktop/test.xlsx".format(home))

# run through the sheets and store sheets in workbook
# this still doesn't write to the file yet
for sheet in sheets: # write data from old file
    newSheet = wb.add_worksheet(sheet.name)
    for row in range(sheet.nrows):
        for col in range(sheet.ncols):
            newSheet.write(row, col, sheet.cell(row, col).value)

for row in range(10, 20): # write NEW data
    for col in range(20):
        newSheet.write(row, col, "test ({}, {})".format(row, col))
wb.close() # THIS writes

However, I found that it was easier to read the data and store into a 2-dimensional array because I was manipulating the data and was receiving input over and over again and did not want to write to the excel file until it the test was over (which you could just as easily do with xlsxwriter since that is probably what they do anyway until you call .close()).

One more way to select between dates in SQLite is to use the powerful strftime function:

SELECT * FROM test WHERE strftime('%Y-%m-%d', date) BETWEEN "11-01-2011" AND "11-08-2011"

These are equivalent according to https://sqlite.org/lang_datefunc.html:

date(...)

strftime('%Y-%m-%d', ...)

but if you want more choice, you have it.

With SNI

If the remote server is using SNI (that is, sharing multiple SSL hosts on a single IP address) you will need to send the correct hostname in order to get the right certificate.

openssl s_client -showcerts -servername www.example.com -connect www.example.com:443 </dev/null

Without SNI

If the remote server is not using SNI, then you can skip -servername parameter:

openssl s_client -showcerts -connect www.example.com:443 </dev/null

To view the full details of a site's cert you can use this chain of commands as well:

$ echo | \
    openssl s_client -servername www.example.com -connect www.example.com:443 2>/dev/null | \
    openssl x509 -text

In 2019, this is a quite recent link from Microsoft about how to obtain this tool:

The SignTool tool is a command-line tool that digitally signs files, verifies signatures in files, or time stamps files. For information about why signing files is important, see Introduction to Code Signing. The tool is installed in the \Bin folder of the Microsoft Windows Software Development Kit (SDK) installation path.

SignTool is available as part of the Windows SDK, which you can download from https://go.microsoft.com/fwlink/p/?linkid=84091.

I only needed signtool, so I chose the minimal I came up with and signtool.exe is now in C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\signtool.exe

this my item . implement Serializable and create ArrayList

ArrayList<StructMain> items =new ArrayList<>();

and put in Bundle

Bundle bundle=new Bundle();
bundle.putSerializable("test",items);

and create a new Intent that put Bundle to Intent

Intent intent=new Intent(ActivityOne.this,ActivityTwo.class);
intent.putExtras(bundle);

If your makefile may be running on non-Cygwin Windows, uname may not be available. That's awkward, but this is a potential solution. You have to check for Cygwin first to rule it out, because it has WINDOWS in its PATH environment variable too.

ifneq (,$(findstring /cygdrive/,$(PATH)))
    UNAME := Cygwin
else
ifneq (,$(findstring WINDOWS,$(PATH)))
    UNAME := Windows
else
    UNAME := $(shell uname -s)
endif
endif

I think the $emit function works better for what I think you're asking for. It keeps your component separated from the Vue instance so that it is reusable in many contexts.

// Child component
<template>
  <div id="app">
    <test @click="$emit('test-click')"></test>
  </div>
</template>

Use it in HTML

// Parent component
<test @test-click="testFunction">

Check out this page which has an example of how to do it.

This script searches for non-ascii characters in one column. It generates a string of all valid characters, here code point 32 to 127. Then it searches for rows that don't match the list:

declare @str varchar(128)
declare @i int
set @str = ''
set @i = 32
while @i <= 127
    begin
    set @str = @str + '|' + char(@i)
    set @i = @i + 1
    end

select  col1
from    YourTable
where   col1 like '%[^' + @str + ']%' escape '|'

Try -

Call CatSubProduktAreakum(Stattyp, Daty + UBound(SubCategories) + 2)

As for the reason, this from MSDN via this question - What does the Call keyword do in VB6?

You are not required to use the Call keyword when calling a procedure. However, if you use the Call keyword to call a procedure that requires arguments, argumentlist must be enclosed in parentheses. If you omit the Call keyword, you also must omit the parentheses around argumentlist. If you use either Call syntax to call any intrinsic or user-defined function, the function's return value is discarded.

Move the long task to a seperate class. Implement it as a subject-observer pattern. Whenever the activity is created register and while closing unregister with the task class. Task class can use AsyncTask.

You could solve this with some simple gazpacho parsing:

from gazpacho import Soup

soup = Soup(html)
tds = soup.find("td", {"class": "pos"})
tds[1].find("strong").text

Which will output:

text I am looking for

You can use moment() and format() functions in AngularJS.

Controller:

var app = angular.module('demoApp', []);   
app.controller( 'demoCtrl', ['$scope', '$moment' function($scope , $moment) {
$scope.date = $moment().format('MM/DD/YYYY');
}]);

View:

<div ng-app="demoApp">
  <div ng-controller="demoCtrl">
    {{date}}
  </div>
</div>

I used a combination of the above solutions and some trial and error to come to this solution. Took me an annoying amount of time so I hope this can help someone else in the future. I also noticed that the date picker input is not at all supported by Safari...

I am using styled-components to render a transparent date picker input as shown in the image below:

const StyledInput = styled.input`
  appearance: none;
  box-sizing: border-box;
  border: 1px solid black;
  background: transparent;
  font-size: 1.5rem;
  padding: 8px;
  ::-webkit-datetime-edit-text { padding: 0 2rem; }
  ::-webkit-datetime-edit-month-field { text-transform: uppercase; }
  ::-webkit-datetime-edit-day-field { text-transform: uppercase; }
  ::-webkit-datetime-edit-year-field { text-transform: uppercase; }
  ::-webkit-inner-spin-button { display: none; }
  ::-webkit-calendar-picker-indicator { background: transparent;}
`

In the jquery ready function you can do something like below -

var hrefcode = $('a[id*=linkbutton]').attr('href').split(':');
var onclickcode = "javascript: if`(Condition()) {" + hrefcode[1] + ";}";
$('a[id*=linkbutton]').attr('href', onclickcode);

In Angular material label with checkbox

<mat-checkbox>Check me!</mat-checkbox>

While you could use a continue, why not just inverse the logic in your if?

while(rs.next())
{
    if(!f.exists() || f.isDirectory()){
    //proceed
    }
}

You don't even need an else {continue;} as it will continue anyway if the if conditions are not satisfied.

Chances are that you've not included the header file that declares system().

In order to be able to compile C++ code that uses functions which you don't (manually) declare yourself, you have to pull in the declarations. These declarations are normally stored in so-called header files that you pull into the current translation unit using the #include preprocessor directive. As the code does not #include the header file in which system() is declared, the compilation fails.

To fix this issue, find out which header file provides you with the declaration of system() and include that. As mentioned in several other answers, you most likely want to add #include <cstdlib>

dt.AsEnumerable()
    .GroupBy(r => new { Col1 = r["Col1"], Col2 = r["Col2"] })
    .Select(g =>
    {
        var row = dt.NewRow();

        row["PK"] = g.Min(r => r.Field<int>("PK"));
        row["Col1"] = g.Key.Col1;
        row["Col2"] = g.Key.Col2;

        return row;

    })
    .CopyToDataTable();

All This Work :)

If you're using jQuery, here's a nice simple method

$("#dateField").val(new Date().toISOString().substring(0, 10));

Or there's the old traditional way:

document.getElementById("dateField").value = new Date().toISOString().substring(0, 10)

If i understand you correctly then in c# the yield return compiler magic is all you need i think.

e.g.

IEnumerable<string> myMethod(IEnumerable<string> sequence)
{
    foreach(string item in sequence)
    {
         yield return item + "roxxors";
    }
}

You need to instantiate an object in order to call its member functions. The member functions need an object to operate on; they can't just be used on their own. The main() function could, for example, look like this:

int main()
{
   Name_pairs np;
   cout << "Enter names and ages. Use 0 to cancel.\n";
   while(np.test())
   {
      np.read_names();
      np.read_ages();
   }
   np.print();
   keep_window_open();
}

Slightly different approach:

MultiValueMap<String, String> headers = new LinkedMultiValueMap<String, String>();
headers.add("HeaderName", "value");
headers.add("Content-Type", "application/json");

RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());

HttpEntity<ObjectToPass> request = new HttpEntity<ObjectToPass>(objectToPass, headers);

restTemplate.postForObject(url, request, ClassWhateverYourControllerReturns.class);

Using .editorconfig to fix the tabs automagically:

root = true

[*]
charset = utf-8
end_of_line = lf
insert_final_newline = true
indent_style = space
indent_size = 4

[Makefile]
indent_style = tab

I like the urllib.urlencode function, and it doesn't appear to exist in urllib2.

Architecture are "the design decisions that are hard to change."

After working with TDD, which practically means that your design changes all the time, I often found myself struggling with this question. The definition above is extracted from Patterns of Enterprise Application Architecture, By Martin Fowler

It means that the architecture depends on the Language, Framework and the Domain of your system. If your can just extract an interface from your Java Class in 5 minutes it is no longer and architecture decision.

See http://developer.android.com/reference/android/R.attr.html#state_above_anchor for a list of available states.

If you want to set colors for disabled, unfocused, unchecked states etc. just negate the states:

int[][] states = new int[][] {
    new int[] { android.R.attr.state_enabled}, // enabled
    new int[] {-android.R.attr.state_enabled}, // disabled
    new int[] {-android.R.attr.state_checked}, // unchecked
    new int[] { android.R.attr.state_pressed}  // pressed
};

int[] colors = new int[] {
    Color.BLACK,
    Color.RED,
    Color.GREEN,
    Color.BLUE
};

ColorStateList myList = new ColorStateList(states, colors);

Magic Number Vs. Symbolic Constant: When to replace?

Magic: Unknown semantic

Symbolic Constant -> Provides both correct semantic and correct context for use

Semantic: The meaning or purpose of a thing.

"Create a constant, name it after the meaning, and replace the number with it." -- Martin Fowler

First, magic numbers are not just numbers. Any basic value can be "magic". Basic values are manifest entities such as integers, reals, doubles, floats, dates, strings, booleans, characters, and so on. The issue is not the data type, but the "magic" aspect of the value as it appears in our code text.

What do we mean by "magic"? To be precise: By "magic", we intend to point to the semantics (meaning or purpose) of the value in the context of our code; that it is unknown, unknowable, unclear, or confusing. This is the notion of "magic". A basic value is not magic when its semantic meaning or purpose-of-being-there is quickly and easily known, clear, and understood (not confusing) from the surround context without special helper words (e.g. symbolic constant).

Therefore, we identify magic numbers by measuring the ability of a code reader to know, be clear, and understand the meaning and purpose of a basic value from its surrounding context. The less known, less clear, and more confused the reader is, the more "magic" the basic value is.

Helpful Definitions

• confuse: cause (someone) to become bewildered or perplexed.
• bewildered: cause (someone) to become perplexed and confused.
• perplexed: completely baffled; very puzzled.
• baffled: totally bewilder or perplex.
• puzzled: unable to understand; perplexed.
• understand: perceive the intended meaning of (words, a language, or speaker).
• meaning: what is meant by a word, text, concept, or action.
• meant: intend to convey, indicate, or refer to (a particular thing or notion); signify.
• signify: be an indication of.
• indication: a sign or piece of information that indicates something.
• indicate: point out; show.
• sign: an object, quality, or event whose presence or occurrence indicates the probable presence or occurrence of something else.

Basics

We have two scenarios for our magic basic values. Only the second is of primary importance for programmers and code:

1. A lone basic value (e.g. number) from which its meaning is unknown, unknowable, unclear or confusing.
2. A basic value (e.g. number) in context, but its meaning remains unknown, unknowable, unclear or confusing.

An overarching dependency of "magic" is how the lone basic value (e.g. number) has no commonly known semantic (like Pi), but has a locally known semantic (e.g. your program), which is not entirely clear from context or could be abused in good or bad context(s).

The semantics of most programming languages will not allow us to use lone basic values, except (perhaps) as data (i.e. tables of data). When we encounter "magic numbers", we generally do so in a context. Therefore, the answer to

"Do I replace this magic number with a symbolic constant?"

is:

"How quickly can you assess and understand the semantic meaning of the number (its purpose for being there) in its context?"

Kind of Magic, but not quite

With this thought in mind, we can quickly see how a number like Pi (3.14159) is not a "magic number" when placed in proper context (e.g. 2 x 3.14159 x radius or 2*Pi*r). Here, the number 3.14159 is mentally recognized Pi without the symbolic constant identifier.

Still, we generally replace 3.14159 with a symbolic constant identifier like Pi because of the length and complexity of the number. The aspects of length and complexity of Pi (coupled with a need for accuracy) usually means the symbolic identifier or constant is less prone to error. Recognition of "Pi" as a name is a simply a convenient bonus, but is not the primary reason for having the constant.

Meanwhile: Back at the Ranch

Laying aside common constants like Pi, let's focus primarily on numbers with special meanings, but which those meanings are constrained to the universe of our software system. Such a number might be "2" (as a basic integer value).

If I use the number 2 by itself, my first question might be: What does "2" mean? The meaning of "2" by itself is unknown and unknowable without context, leaving its use unclear and confusing. Even though having just "2" in our software will not happen because of language semantics, we do want to see that "2" by itself carries no special semantics or obvious purpose being alone.

Let's put our lone "2" in a context of: padding := 2, where the context is a "GUI Container". In this context the meaning of 2 (as pixels or other graphical unit) offers us a quick guess of its semantics (meaning and purpose). We might stop here and say that 2 is okay in this context and there is nothing else we need to know. However, perhaps in our software universe this is not the whole story. There is more to it, but "padding = 2" as a context cannot reveal it.

Let's further pretend that 2 as pixel padding in our program is of the "default_padding" variety throughout our system. Therefore, writing the instruction padding = 2 is not good enough. The notion of "default" is not revealed. Only when I write: padding = default_padding as a context and then elsewhere: default_padding = 2 do I fully realize a better and fuller meaning (semantic and purpose) of 2 in our system.

The example above is pretty good because "2" by itself could be anything. Only when we limit the range and domain of understanding to "my program" where 2 is the default_padding in the GUI UX parts of "my program", do we finally make sense of "2" in its proper context. Here "2" is a "magic" number, which is factored out to a symbolic constant default_padding within the context of the GUI UX of "my program" in order to make it use as default_padding quickly understood in the greater context of the enclosing code.

Thus, any basic value, whose meaning (semantic and purpose) cannot be sufficiently and quickly understood is a good candidate for a symbolic constant in the place of the basic value (e.g. magic number).

Going Further

Numbers on a scale might have semantics as well. For example, pretend we are making a D&D game, where we have the notion of a monster. Our monster object has a feature called life_force, which is an integer. The numbers have meanings that are not knowable or clear without words to supply meaning. Thus, we begin by arbitrarily saying:

• full_life_force: INTEGER = 10 -- Very alive (and unhurt)
• minimum_life_force: INTEGER = 1 -- Barely alive (very hurt)
• dead: INTEGER = 0 -- Dead
• undead: INTEGER = -1 -- Min undead (almost dead)
• zombie: INTEGER = -10 -- Max undead (very undead)

From the symbolic constants above, we start to get a mental picture of the aliveness, deadness, and "undeadness" (and possible ramifications or consequences) for our monsters in our D&D game. Without these words (symbolic constants), we are left with just the numbers ranging from -10 .. 10. Just the range without the words leaves us in a place of possibly great confusion and potentially with errors in our game if different parts of the game have dependencies on what that range of numbers means to various operations like attack_elves or seek_magic_healing_potion.

Therefore, when searching for and considering replacement of "magic numbers" we want to ask very purpose-filled questions about the numbers within the context of our software and even how the numbers interact semantically with each other.

Conclusion

Let's review what questions we ought to ask:

You might have a magic number if ...

1. Can the basic value have a special meaning or purpose in your softwares universe?
2. Can the special meaning or purpose likely be unknown, unknowable, unclear, or confusing, even in its proper context?
3. Can a proper basic value be improperly used with bad consequences in the wrong context?
4. Can an improper basic value be properly used with bad consequences in the right context?
5. Does the basic value have a semantic or purpose relationships with other basic values in specific contexts?
6. Can a basic value exist in more than one place in our code with different semantics in each, thereby causing our reader a confusion?

Examine stand-alone manifest constant basic values in your code text. Ask each question slowly and thoughtfully about each instance of such a value. Consider the strength of your answer. Many times, the answer is not black and white, but has shades of misunderstood meaning and purpose, speed of learning, and speed of comprehension. There is also a need to see how it connects to the software machine around it.

In the end, the answer to replacement is answer the measure (in your mind) of the strength or weakness of the reader to make the connection (e.g. "get it"). The more quickly they understand meaning and purpose, the less "magic" you have.

CONCLUSION: Replace basic values with symbolic constants only when the magic is large enough to cause difficult to detect bugs arising from confusions.

For someone doing everything described here and still can't access:

XAMPP with Apache HTTP Server 2.4:

In file httpd-vhost.conf:

<VirtualHost *>
    DocumentRoot "D:/xampp/htdocs/dir"
    ServerName something.dev
   <Directory "D:/xampp/htdocs/dir">
    Require all granted #apache v 2.4.4 uses just this
   </Directory>
</VirtualHost>

There isn't any need for a port, or an IP address here. Apache configures it on its own files. There isn't any need for NameVirtualHost *:80; it's deprecated. You can use it, but it doesn't make any difference.

Then to edit hosts, you must run Notepad as administrator (described bellow). If you were editing the file without doing this, you are editing a pseudo file, not the original (yes, it saves, etc., but it's not the real file)

In Windows:

Find the Notepad icon, right click, run as administrator, open file, go to C:/WINDOWS/system32/driver/etc/hosts, check "See all files", and open hosts.

If you where editing it before, probably you will see it's not the file you were previously editing when not running as administrator.

Then to check if Apache is reading your httpd-vhost.conf, go to folder xampFolder/apache/bin, Shift + right click, open a terminal command here, open XAMPP (as you usually do), start Apache, and then on the command line, type httpd -S. You will see a list of the virtual hosts. Just check if your something.dev is there.

Waterfall methodology is a sequential design process. This means that as each of the eight stages (conception, initiation, analysis, design, construction, testing, implementation, and maintenance) are completed, the developers move on to the next step.

As this process is sequential, once a step has been completed, developers can’t go back to a previous step – not without scratching the whole project and starting from the beginning. There’s no room for change or error, so a project outcome and an extensive plan must be set in the beginning and then followed careful

ACP Agile Certification came about as a “solution” to the disadvantages of the waterfall methodology. Instead of a sequential design process, the Agile methodology follows an incremental approach. Developers start off with a simplistic project design, and then begin to work on small modules. The work on these modules is done in weekly or monthly sprints, and at the end of each sprint, project priorities are evaluated and tests are run. These sprints allow for bugs to be discovered, and customer feedback to be incorporated into the design before the next sprint is run.

The process, with its lack of initial design and steps, is often criticized for its collaborative nature that focuses on principles rather than process.

This is simple code, so if you are new you should understand it easily enough.

    mylist = ["x", 3, "b"]
    for items in mylist:
        print(items)

It prints all of them without quotes, like you wanted.

If I may I could give you some new code for the same task, in my code you can create a so called 'document'(not really)and it is saved, and can be opened up again. It is also stored as a string file though(not a document). Here is the code:

#include "iostream"

#include "windows.h"

#include "string"

#include "fstream"

using namespace std;

int main() {

string saveload;


cout << "---------------------------" << endl;
cout << "|enter 'text' to write your document    |" << endl;
cout << "|enter 'open file' to open the document |" << endl;
cout << "----------------------------------------" << endl;
while (true){
    getline(cin, saveload);

    if (saveload == "open file"){
        string filenamet;
        cout << "file name? " << endl;
        getline(cin, filenamet, '*');
        ifstream loadFile;

        loadFile.open(filenamet, ifstream::in);

        cout << "the text you entered was: ";

        while (loadFile.good()){

            cout << (char)loadFile.get();

            Sleep(100);
        }

        cout << "" << endl;

        loadFile.close();

    }

    if (saveload == "text") {
        string filename;
        cout << "file name: " << endl;
        getline(cin, filename,'*');
        string textToSave;
        cout << "Enter your text: " << endl;
        getline(cin, textToSave,'*');

        ofstream saveFile(filename);

        saveFile << textToSave;

        saveFile.close();

    }
}
return 0;
}

Just take this code and change it to serve your purpose. DREAM BIG,THINK BIG, DO BIG

It happens because you have not installed the minSdkVersion or targetSdkVersion in you’re computer. I've tested it right now.

For example, if you have those lines in your Manifest.xml:

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />

And you have installed only the API17 in your computer, it will report you an error. If you want to test it, try installing the other API version (in this case, API 8).

Even so, it's not an important error. It doesn't mean that your app is wrong.

Sorry about my expression. English is not my language. Bye!

If you may want to convert plaintext (not just numbers) to a BigInteger you will run into an exception, if you just try to: new BigInteger("not a Number")

In this case you could do it like this way:

public  BigInteger stringToBigInteger(String string){
    byte[] asciiCharacters = string.getBytes(StandardCharsets.US_ASCII);
    StringBuilder asciiString = new StringBuilder();
    for(byte asciiCharacter:asciiCharacters){
        asciiString.append(Byte.toString(asciiCharacter));
    }
    BigInteger bigInteger = new BigInteger(asciiString.toString());
    return bigInteger;
}

I know this is old, but I figured I'd give my input. I had to do this for a project at work and this was my solution.

I have a Building object that includes the Timezone using the TimeZone class and wanted to create zoneId and offset fields in a new class.

So what I did was create:

private String timeZoneId;
private String timeZoneOffset;

Then in the constructor I passed in the Building object and set these fields like so:

this.timeZoneId = building.getTimeZone().getID();
this.timeZoneOffset = building.getTimeZone().toZoneId().getId();

So timeZoneId might equal something like "EST" And timeZoneOffset might equal something like "-05:00"

I would like to not that you might not

I came across a similar issue but instead of changing the regedit I decided to change the Chrome settings

Try the following steps

1. In the chrome browser type: chrome://plugins/
2. Click on + Details (top right corner) to expand all the plugin details.
3. Find Java and click on Disable for the path(s) that you don't want to be used.

You might have to restart the browser to see the changes. This also assumes that the Java that you have enabled is the latest Java.

Hope this helps

Slightly different from what you described, but I think this might be what you actually need:

svn blame filename

It will print the file with each line prefixed by the time and author of the commit that last changed it.

I have Written a small script to download the live youtube video, you may use as single command as well. script it can be invoked simply as,

~/ytdl_lv.sh <URL> <output file name>

e.g.

~/ytdl_lv.sh https://www.youtube.com/watch?v=BLIGxsYLyjc myfile.mp4

script is as simple as below,

#!/bin/bash 

# ytdl_lv.sh
# Author Prashant
# 

URL=$1 
OUTNAME=$2
streamlink --hls-live-restart -o ${OUTNAME} ${URL} best

here the best is the stream quality, it also can be 144p (worst), 240p, 360p, 480p, 720p (best)

The easiest way to compute the correct mouse click or mouse move position on a canvas event is to use this little equation:

canvas.addEventListener('click', event =>
{
    let bound = canvas.getBoundingClientRect();

    let x = event.clientX - bound.left - canvas.clientLeft;
    let y = event.clientY - bound.top - canvas.clientTop;

    context.fillRect(x, y, 16, 16);
});

If the canvas has padding-left or padding-top, subtract x and y via:

x -= parseFloat(style['padding-left'].replace('px'));
y -= parseFloat(style['padding-top'].replace('px'));

Java makes regex too complicated and it does not follow the perl-style. Take a look at MentaRegex to see how you can accomplish that in a single line of Java code:

String[] matches = match("aa11bb22", "/(\\d+)/g" ); // => ["11", "22"]

Alternatively, by changing a line of the above code:

# df.date = df.date.apply(lambda d: datetime.strptime(d, "%Y-%m-%d"))
df.date = df.date.apply(lambda d: datetime.datetime.fromtimestamp(int(d)).strftime('%Y-%m-%d'))

It should also work.

You don't need to convert it at all:

% perl -e 'print "5.45" + 0.1;'
5.55

you can use flushall in your terminal

redis-cli> flushall

I haven't timed it but I suspect this would be pretty quick:

import numpy as np
list1=[1, 2, 3]
list2=[4, 5, 6]

list_sum = (np.add(list1, list2)).tolist()

[5, 7, 9]

You need to wrap them all in a character class. The current version means replace this sequence of characters with an empty string. When wrapped in square brackets it means replace any of these characters with an empty string.

var cleanString = dirtyString.replace(/[\|&;\$%@"<>\(\)\+,]/g, "");

(Edit: Forget my previous babble...)

Ok, there might be situations where you would go either to the model or to some other url... But I don't really think this belongs in the model, the view (or maybe the model) sounds more apropriate.

About the routes, as far as I know the routes is for the actions in controllers (wich usually "magically" uses a view), not directly to views. The controller should handle all requests, the view should present the results and the model should handle the data and serve it to the view or controller. I've heard a lot of people here talking about routes to models (to the point I'm allmost starting to beleave it), but as I understand it: routes goes to controllers. Of course a lot of controllers are controllers for one model and is often called <modelname>sController (e.g. "UsersController" is the controller of the model "User").

If you find yourself writing nasty amounts of logic in a view, try to move the logic somewhere more appropriate; request and internal communication logic probably belongs in the controller, data related logic may be placed in the model (but not display logic, which includes link tags etc.) and logic that is purely display related would be placed in a helper.

Catching errors has been very well discussed here, but it's worth remembering to log the errors out somewhere so you can view them and fix stuff up.

?Bunyan is a popular logging framework for NodeJS - it supporst writing out to a bunch of different output places which makes it useful for local debugging, as long as you avoid console.log. ? In your domain's error handler you could spit the error out to a log file.

var log = bunyan.createLogger({
  name: 'myapp',
  streams: [
    {
      level: 'error',
      path: '/var/tmp/myapp-error.log'  // log ERROR to this file
    }
  ]
});

This can get time consuming if you have lots of errors and/or servers to check, so it could be worth looking into a tool like Raygun (disclaimer, I work at Raygun) to group errors together - or use them both together. ? If you decided to use Raygun as a tool, it's pretty easy to setup too

var raygunClient = new raygun.Client().init({ apiKey: 'your API key' });
raygunClient.send(theError);

? Crossed with using a tool like PM2 or forever, your app should be able to crash, log out what happened and reboot without any major issues.

This is not accurate ---> "...* pass array. arrays are passed by reference. i.e. if you pass array of integers, modified the array inside the method.

Every parameter type is passed by value in Java. Arrays are object, its object reference is passed by value.

This includes an array of primitives (int, double,..) and objects. The integer value is changed by the methodTwo() but it is still the same arr object reference, the methodTwo() cannot add an array element or delete an array element. methodTwo() cannot also, create a new array then set this new array to arr. If you really can pass an array by reference, you can replace that arr with a brand new array of integers.

Every object passed as parameter in Java is passed by value, no exceptions.

If the image is too large and you can't save&load it to the storage, you should consider just using a global static reference to the bitmap (inside the receiving activity), which will be reset to null on onDestory, only if "isChangingConfigurations" returns true.

Edit:

It actually just occurred to me that in Xcode 7b4, UI testing now has expectationForPredicate:evaluatedWithObject:handler:

Original:

Another way is to spin the run loop for a set amount of time. Really only useful if you know how much (estimated) time you'll need to wait for

Obj-C: [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate dateWithTimeIntervalSinceNow: <<time to wait in seconds>>]]

Swift: NSRunLoop.currentRunLoop().runMode(NSDefaultRunLoopMode, beforeDate: NSDate(timeIntervalSinceNow: <<time to wait in seconds>>))

This is not super useful if you need to test some conditions in order to continue your test. To run conditional checks, use a while loop.

I ran across this looking for a way to do a max-margin for responsive design. I need a 5% margin for mobile/tablet devices up to 48 pixels wide. Berd gave me the answer by using media queries.

My answer: 48 * 2 = 96 total max margin 96 is 10% of total width. 10 * 96 = (960) 100% of vw where 48px is the first time I want it to overwrite the % .

So my media queries to control my margins become:

@media (max-width: 959px) {
    .content {
        margin: 30px 5% 48px;
    }
}
@media (min-width: 960px) {
    .content {
        display:block;
        margin: 30px 48px 48px;
    }
}

i did try this and its working in windows machine to run a sql file on a specific schema.

psql -h localhost -p 5432 -U username -d databasename -v schema=schemaname < e:\Table.sql

I had the similar problem: EOF -warning and only part of data was loading with read.csv(). I tried the quotes="", but it only removed the EOF -warning.

But looking at the first row that was not loading, I found that there was a special character, an arrow ? (hexadecimal value 0x1A) in one of the cells. After deleting the arrow I got the data to load normally.

I had troubles compiling all the most commonly mentioned cryptography libraries on my Windows 7 system and for Python 3.5.

This is the solution that finally worked for me.

from cryptography.fernet import Fernet
key = Fernet.generate_key() #this is your "password"
cipher_suite = Fernet(key)
encoded_text = cipher_suite.encrypt(b"Hello stackoverflow!")
decoded_text = cipher_suite.decrypt(encoded_text)

doc.id gets the UID.

Combine with the rest of the data for one object like so:

Object.assign({ uid: doc.id }, doc.data())

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.waist2height); {
        final EditText edit = (EditText)findViewById(R.id.editText);          
        final RadioButton rb1 = (RadioButton) findViewById(R.id.radioCM);
        final RadioButton rb2 = (RadioButton) findViewById(R.id.radioFT);                       
        if(rb1.isChecked()){    
            edit.setVisibility(View.VISIBLE);              
        }
        else if(rb2.isChecked()){               
            edit.setVisibility(View.INVISIBLE);
        }
}

Do you want to find the length of the string in python language ? If you want to find the length of the word, you can use the len function.

string = input("Enter the string : ")

print("The string length is : ",len(string))

OUTPUT : -

Enter the string : viral

The string length is : 5

Adding to the evolving nature of the answer to this question, starting with r2016b, MATLAB will implicitly expand singleton dimensions, removing the need for bsxfun in many cases.

From the r2016b release notes:

Implicit Expansion: Apply element-wise operations and functions to arrays with automatic expansion of dimensions of length 1

Implicit expansion is a generalization of scalar expansion. With scalar expansion, a scalar expands to be the same size as another array to facilitate element-wise operations. With implicit expansion, the element-wise operators and functions listed here can implicitly expand their inputs to be the same size, as long as the arrays have compatible sizes. Two arrays have compatible sizes if, for every dimension, the dimension sizes of the inputs are either the same or one of them is 1. See Compatible Array Sizes for Basic Operations and Array vs. Matrix Operations for more information.

Element-wise arithmetic operators — +, -, .*, .^, ./, .\

Relational operators — <, <=, >, >=, ==, ~=

Logical operators — &, |, xor

Bit-wise functions — bitand, bitor, bitxor

Elementary math functions — max, min, mod, rem, hypot, atan2, atan2d

For example, you can calculate the mean of each column in a matrix A, and then subtract the vector of mean values from each column with A - mean(A).

Previously, this functionality was available via the bsxfun function. It is now recommended that you replace most uses of bsxfun with direct calls to the functions and operators that support implicit expansion. Compared to using bsxfun, implicit expansion offers faster speed, better memory usage, and improved readability of code.

UPDATE Just a quick note, as I can see this looks really stupid, and it has no good use with pure PHP because the array_merge just works there. BUT try it with the PHP MongoDB driver before you rush to downvote. That dude WILL add indexes for whatever reason, and WILL ruin the merged object. With my naïve little function, the merge comes out exactly the way it was supposed to with a traditional array_merge.

I know it's an old question but I'd like to add one more case I had recently with MongoDB driver queries and none of array_merge, array_replace nor array_push worked. I had a bit complex structure of objects wrapped as arrays in array:

$a = [
 ["a" => [1, "a2"]],
 ["b" => ["b1", 2]]
];
$t = [
 ["c" => ["c1", "c2"]],
 ["b" => ["b1", 2]]
];

And I needed to merge them keeping the same structure like this:

$merged = [
 ["a" => [1, "a2"]],
 ["b" => ["b1", 2]],
 ["c" => ["c1", "c2"]],
 ["b" => ["b1", 2]]
];

The best solution I came up with was this:

public static function glueArrays($arr1, $arr2) {
    // merges TWO (2) arrays without adding indexing. 
    $myArr = $arr1;
    foreach ($arr2 as $arrayItem) {
        $myArr[] = $arrayItem;
    }
    return $myArr;
}

Redis supports 5 data types. You need to know what type of value that a key maps to, as for each data type, the command to retrieve it is different.

Here are the commands to retrieve key value:

• if value is of type string -> GET <key>
• if value is of type hash -> HGETALL <key>
• if value is of type lists -> lrange <key> <start> <end>
• if value is of type sets -> smembers <key>
• if value is of type sorted sets -> ZRANGEBYSCORE <key> <min> <max>

Use the TYPE command to check the type of value a key is mapping to:

• type <key>

This is simple if you only use Selenium WebDriver, and forget the usage of Selenium-RC. I'd go like this.

WebDriver driver = new FirefoxDriver();
WebElement email = driver.findElement(By.id("email"));
email.sendKeys("[email protected]");

The reason for NullPointerException however is that your variable driver has never been started, you start FirefoxDriver in a variable wb thas is never being used.

Unfortunately you can't use Process.Start() to start an instance of the currently running process. According to the Process.Start() docs: "If the process is already running, no additional process resource is started..."

This technique will work fine under the VS debugger (because VS does some kind of magic that causes Process.Start to think the process is not already running), but will fail when not run under the debugger. (Note that this may be OS-specific - I seem to remember that in some of my testing, it worked on either XP or Vista, but I may just be remembering running it under the debugger.)

This technique is exactly the one used by the last programmer on the project on which I'm currently working, and I've been trying to find a workaround for this for quite some time. So far, I've only found one solution, and it just feels dirty and kludgy to me: start a 2nd application, that waits in the background for the first application to terminate, then re-launches the 1st application. I'm sure it would work, but, yuck.

Edit: Using a 2nd application works. All I did in the second app was:

    static void RestartApp(int pid, string applicationName )
    {
        // Wait for the process to terminate
        Process process = null;
        try
        {
            process = Process.GetProcessById(pid);
            process.WaitForExit(1000);
        }
        catch (ArgumentException ex)
        {
            // ArgumentException to indicate that the 
            // process doesn't exist?   LAME!!
        }
        Process.Start(applicationName, "");
    }

(This is a very simplified example. The real code has lots of sanity checking, error handling, etc)

You can iterate over all network connections and chek whether there is at least one available connection:

public boolean isConnected() {
    boolean connected = false;

    ConnectivityManager cm = 
        (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

    if (cm != null) {
        NetworkInfo[] netInfo = cm.getAllNetworkInfo();

        for (NetworkInfo ni : netInfo) {
            if ((ni.getTypeName().equalsIgnoreCase("WIFI")
                    || ni.getTypeName().equalsIgnoreCase("MOBILE"))
                    && ni.isConnected() && ni.isAvailable()) {
                connected = true;
            }

        }
    }

    return connected;
}

I have done the json parser in simplest way, here it is

package com.inzane.shoapp.activity;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.UnsupportedEncodingException;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.json.JSONException;
import org.json.JSONObject;

import android.util.Log;

public class JSONParser {

static InputStream is = null;
static JSONObject jObj = null;
static String json = "";

// constructor
public JSONParser() {

}

public JSONObject getJSONFromUrl(String url) {

    // Making HTTP request
    try {
        // defaultHttpClient
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);

        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        is = httpEntity.getContent();

    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    try {
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                is, "iso-8859-1"), 8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
            System.out.println(line);
        }
        is.close();
        json = sb.toString();

    } catch (Exception e) {
        Log.e("Buffer Error", "Error converting result " + e.toString());
    }

    // try parse the string to a JSON object
    try {
        jObj = new JSONObject(json);
    } catch (JSONException e) {
        Log.e("JSON Parser", "Error parsing data " + e.toString());
        System.out.println("error on parse data in jsonparser.java");
    }

    // return JSON String
    return jObj;

}
}

this class returns the json object from the url

and when you want the json object you just call this class and the method in your Activity class

my code is here

String url = "your url";
JSONParser jsonParser = new JSONParser();
JSONObject object = jsonParser.getJSONFromUrl(url);
String content=object.getString("json key");

here the "json key" is denoted that the key in your json file

this is a simple json file example

{
    "json":"hi"
}

Here "json" is key and "hi" is value

This will get your json value to string content.

Both top answers are incorrect.

A short one-liner that uses pure JavaScript, accounts for the local timezone and requires no extra functions to be defined:

const element = document.getElementById('date-input');_x000D_
element.valueAsNumber = Date.now()-(new Date()).getTimezoneOffset()*60000;

<input id='date-input' type='date'>

This gets the current datetime in milliseconds (since epoch) and applies the timezone offset in milliseconds (minutes * 60k minutes per millisecond).

You can set the date using element.valueAsDate but then you have an extra call to the Date() constructor.

set the system property log4j.debug=true. Then you can determine where your configuration is running amuck.

As per my understanding data structure is any data residing in memory of any electronic system that can be efficiently managed. Many times it is a game of memory or faster accessibility of data. In terms of memory again, there are tradeoffs done with the management of data based on cost to the company of that end product. Efficiently managed tells us how best the data can be accessed based on the primary requirement of the end product. This is a very high level explanation but data structures is a vast subjects. Most of the interviewers dive into data structures that they can afford to discuss in the interviews depending on the time they have, which are linked lists and related subjects.

Now, these data types can be divided into primitive, abstract, composite, based on the way they are logically constructed and accessed.

• primitive data structures are basic building blocks for all data structures, they have a continuous memory for them: boolean, char, int, float, double, string.
• composite data structures are data structures that are composed of more than one primitive data types.class, structure, union, array/record.
• abstract datatypes are composite datatypes that have way to access them efficiently which is called as an algorithm. Depending on the way the data is accessed data structures are divided into linear and non linear datatypes. Linked lists, stacks, queues, etc are linear data types. heaps, binary trees and hash tables etc are non linear data types.

I hope this helps you dive in.

The collection used in foreach is immutable. This is very much by design.

As it says on MSDN:

The foreach statement is used to iterate through the collection to get the information that you want, but can not be used to add or remove items from the source collection to avoid unpredictable side effects. If you need to add or remove items from the source collection, use a for loop.

The post in the link provided by Poko indicates that this is allowed in the new concurrent collections.

From the XML you can set the textStyle to bold as below

<TextView
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:text="Bold text"
   android:textStyle="bold"/>

You can set the TextView to bold programmatically as below

textview.setTypeface(Typeface.DEFAULT_BOLD);

The big difference is perfectly explained here.

Basically, lightweight tags are just pointers to specific commits. No further information is saved; on the other hand, annotated tags are regular objects, which have an author and a date and can be referred because they have their own SHA key.

If knowing who tagged what and when is relevant for you, then use annotated tags. If you just want to tag a specific point in your development, no matter who and when did that, then lightweight tags are good enough.

Normally you'd go for annotated tags, but it is really up to the Git master of the project.

Use the DataFrame returned by:

yourDF.orderBy(account)

There is no explicit way to use partitionBy on a DataFrame, only on a PairRDD, but when you sort a DataFrame, it will use that in it's LogicalPlan and that will help when you need to make calculations on each Account.

I just stumbled upon the same exact issue, with a dataframe that I want to partition by account. I assume that when you say "want to have the data partitioned so that all of the transactions for an account are in the same Spark partition", you want it for scale and performance, but your code doesn't depend on it (like using mapPartitions() etc), right?

Generally the process will block. If the read operation is on a file descriptor marked as non-blocking or if the process is using asynchronous IO it won't block. Also if the process has other threads that aren't blocked they can continue running.

The decision as to which process runs next is up to the scheduler in the kernel.

You'll need to send the image back base64 encoded, look at this: http://php.net/manual/en/function.base64-encode.php

Then in your ajax call change the success function to this:

$('.div_imagetranscrits').html('<img src="data:image/png;base64,' + data + '" />');

Wildcard works for me also, but I'd like to give a side note for those using directory variables. Always use slash for folder tree (not backslash), otherwise it will fail:

BASEDIR = ../..
SRCDIR = $(BASEDIR)/src
INSTALLDIR = $(BASEDIR)/lib

MODULES = $(wildcard $(SRCDIR)/*.cpp)
OBJS = $(wildcard *.o)

This is because your row variable/tuple does not contain any value for that index. You can try printing the whole list like print(row) and check how many indexes there exists.

With BigDecimal:

long aLong = ...;
int anInt = new BigDecimal(aLong).intValueExact(); // throws ArithmeticException
                                                   // if outside bounds

The quoting rules are painful. I think you want:

SELECT nextval('foo."SQ_ID"');

to prevent case-folding of SQ_ID.

You need to do a deep copy from user to usercopy, and then after your login you can reassign your userCopy reference to user.

User userCopy = new User();
userCopy.Age = user.Age
userCopy.ID = user.ID

foreach(...) 
{ 
  user.Age = 1; 
  user.ID = -1; 

  UserDao.Update(user)     

  user = userCopy;       
}

I have tweaked some of the above post with working example. Here we can give css and js in same array also.

$(document).ready(function(){

if (Array.prototype.contains === undefined) {
Array.prototype.contains = function (obj) {
    var i = this.length;
    while (i--) { if (this[i] === obj) return true; }
    return false;
};
};

    cssJsFileArray.filter((item,index)=>cssJsFileArray.indexOf(item)==index)
    var loadedFileArray = this.loadedFiles;
    $.each(cssJsFileArray, function( index, url ) {
            // if multiple arrays are loaded the check the uniqueness
            if (loadedFileArray.contains(url)) return;
            if( self.jsExpr.test( url ) ){
                $.get(url, function(data) {

                    self.addCss(data);
                });
            }

Dispose() calls the code below, which closes the connections opened by the HttpClient instance. The code was created by decompiling with dotPeek.

HttpClientHandler.cs - Dispose

ServicePointManager.CloseConnectionGroups(this.connectionGroupName);

If you don't call dispose then ServicePointManager.MaxServicePointIdleTime, which runs by a timer, will close the http connections. The default is 100 seconds.

ServicePointManager.cs

internal static readonly TimerThread.Callback s_IdleServicePointTimeoutDelegate = new TimerThread.Callback(ServicePointManager.IdleServicePointTimeoutCallback);
private static volatile TimerThread.Queue s_ServicePointIdlingQueue = TimerThread.GetOrCreateQueue(100000);

private static void IdleServicePointTimeoutCallback(TimerThread.Timer timer, int timeNoticed, object context)
{
  ServicePoint servicePoint = (ServicePoint) context;
  if (Logging.On)
    Logging.PrintInfo(Logging.Web, SR.GetString("net_log_closed_idle", (object) "ServicePoint", (object) servicePoint.GetHashCode()));
  lock (ServicePointManager.s_ServicePointTable)
    ServicePointManager.s_ServicePointTable.Remove((object) servicePoint.LookupString);
  servicePoint.ReleaseAllConnectionGroups();
}

If you haven't set the idle time to infinite then it appears safe not to call dispose and let the idle connection timer kick-in and close the connections for you, although it would be better for you to call dispose in a using statement if you know you are done with an HttpClient instance and free up the resources faster.

If you want to print more than a single result, just select rows into a temporary table, then select from that temp table into a buffer, then print the buffer:

drop table if exists #temp

-- we just want to see our rows, not how many were inserted
set nocount on

select * into #temp from MyTable

-- note: SSMS will only show 8000 chars
declare @buffer varchar(MAX) = ''

select @buffer = @buffer + Col1 + ' ' + Col2 + CHAR(10) from #temp

print @buffer

If you're a Tidyverse kind of person, here's the stringr solution:

R> library(stringr)
R> strings = c("TGAS_1121", "MGAS_1432", "ATGAS_1121") 
R> strings %>% str_replace(".*_", "_")
[1] "_1121" "_1432" "_1121"
# Or:
R> strings %>% str_replace("^[A-Z]*", "")
[1] "_1121" "_1432" "_1121"

if(data.trim()==''){alert("Nothing Found");}

You could try this simple approach

var array1 = [4,8,9,10];_x000D_
var array2 = [4,8,9,10];_x000D_
_x000D_
console.log(array1.join('|'));_x000D_
console.log(array2.join('|'));_x000D_
_x000D_
if (array1.join('|') === array2.join('|')) {_x000D_
 console.log('The arrays are equal.');_x000D_
} else {_x000D_
 console.log('The arrays are NOT equal.');_x000D_
}_x000D_
_x000D_
array1 = [[1,2],[3,4],[5,6],[7,8]];_x000D_
array2 = [[1,2],[3,4],[5,6],[7,8]];_x000D_
_x000D_
console.log(array1.join('|'));_x000D_
console.log(array2.join('|'));_x000D_
_x000D_
if (array1.join('|') === array2.join('|')) {_x000D_
 console.log('The arrays are equal.');_x000D_
} else {_x000D_
 console.log('The arrays are NOT equal.');_x000D_
}

If the position of the values are not important you could sort the arrays first.

if (array1.sort().join('|') === array2.sort().join('|')) {
    console.log('The arrays are equal.');
} else {
    console.log('The arrays are NOT equal.');
}

CTRL+r

The "r" is lower-case.

What it is telling you is - the 2nd guard let or the if let check is not happening on an Optional Int or Optional String. You already have a non-optional value, so guarding or if-letting is not needed anymore

The following approach helped me.

Steps :

1.Go to the corresponding directory where the header file that is missing is located. (In my case,../include/unicode/coll.h was missing) and copy the directory location where the header file is located.(Copy till the include directory.)

2.Right click on your project in the Solution Explorer->Properties->Configuration Properties->VC++ Directories->Include Directories. Paste the copied path here.

3.This solved my problem.I hope this helps !

.service-small option {
    font-size: 14px;
    padding: 5px;
    background: #5c5c5c;
}

I think it because you used .styled-select in start of the class code.

• right-click virtual directory (e.g. MyVirtualDirectory)

• click convert to application.

For Python3.x and starting Pillow==6.0.0, Image objects now provide a getexif() method that returns a <class 'PIL.Image.Exif'> instance or None if the image has no EXIF data.

From Pillow 6.0.0 release notes:

getexif() has been added, which returns an Exif instance. Values can be retrieved and set like a dictionary. When saving JPEG, PNG or WEBP, the instance can be passed as an exif argument to include any changes in the output image.

As stated, you can iterate over the key-value pairs of the Exif instance like a regular dictionary. The keys are 16-bit integers that can be mapped to their string names using the ExifTags.TAGS module.

from PIL import Image, ExifTags

img = Image.open("sample.jpg")
img_exif = img.getexif()
print(type(img_exif))
# <class 'PIL.Image.Exif'>

if img_exif is None:
    print('Sorry, image has no exif data.')
else:
    for key, val in img_exif.items():
        if key in ExifTags.TAGS:
            print(f'{ExifTags.TAGS[key]}:{val}')
            # ExifVersion:b'0230'
            # ...
            # FocalLength:(2300, 100)
            # ColorSpace:1
            # ...
            # Model:'X-T2'
            # Make:'FUJIFILM'
            # LensSpecification:(18.0, 55.0, 2.8, 4.0)
            # ...
            # DateTime:'2019:12:01 21:30:07'
            # ...

Tested with Python 3.8.8 and Pillow==8.1.0.

There is a bunch on here:

Just google for "Free WebService" or "Open WebService" and you'll find tons of open SOAP endpoints.

Remember, you can get a WSDL from any ASMX endpoint by adding ?WSDL to the url.

Here is my answer when you want to animate it and start fading it out after couple of seconds. I used opacity because first of all i didn't want to fade it out completely, second, it does not go back and force after many scrolls.

$(window).scroll(function () {
    var elem = $('div');
    setTimeout(function() {
        elem.css({"opacity":"0.2","transition":"2s"});
    },4000);            
    elem.css({"opacity":"1","transition":"1s"});    
});

In 32 bit format system the hexadecimal value 0xff represents 00000000000000000000000011111111 that is 255(15*16^1+15*16^0) in decimal. and the bitwise & operator masks the same 8 right most bits as in first operand.

You can add "issue time" to token and maintain "last logout time" for each user on the server. When you check token validity, also check "issue time" be after "last logout time".

If you are using "MVC 5" you may not see the file, and you should follow these steps: http://www.techjunkieblog.com/2015/05/aspnet-mvc-empty-project-adding.html

If you are using "ASP.NET 5" it has stopped using "bundling and minification" instead was replaced by gulp, bower, and npm. More information see https://jeffreyfritz.com/2015/05/where-did-my-asp-net-bundles-go-in-asp-net-5/

You simply must rewrite it like that:

var response = '';
$.ajax({ type: "GET",   
         url: "http://www.google.de",   
         async: false,
         success : function(text)
         {
             response = text;
         }
});

alert(response);

You use the id property to the get the id, then the substr method to remove the first part of it, then optionally parseInt to turn it into a number:

var id = theElement.id.substr(5);

or:

var id = parseInt(theElement.id.substr(5));

You can do this locally as everyone mentioned using

git checkout -b <branch-name> <sha1-of-commit>

Alternatively, you can do this in github itself, follow the steps:

1- In the repository, click on the Commits.

2- on the commit you want to branch from, click on <> to browse the repository at this point in the history.

3- Click on the tree: xxxxxx in the upper left. Just type in a new branch name there click Create branch xxx as shown below.

Now you can fetch the changes from that branch locally and continue from there.

unsigned char is the heart of all bit trickery. In almost ALL compiler for ALL platform an unsigned char is simply a byte and an unsigned integer of (usually) 8 bits that can be treated as a small integer or a pack of bits.

In addiction, as someone else has said, the standard doesn't define the sign of a char. so you have 3 distinct char types: char, signed char, unsigned char.

You can use peek to do that.

List<Fruit> newList = fruits.stream()
    .peek(f -> f.setName(f.getName() + "s"))
    .collect(Collectors.toList());

This will do the trick:

xargs -0 < /proc/<pid>/cmdline

Without the xargs, there will be no spaces between the arguments, because they have been converted to NULs.

You can get the DOM element, and set the disabled property directly.

$(".shownextrow").click(function() { 
  $(this).closest("tr").next().show()
          .find('.longboxsmall').hide()[0].disabled = 'disabled';
});

or if there's more than one, you can use each() to set all of them:

$(".shownextrow").click(function() { 
  $(this).closest("tr").next().show()
          .find('.longboxsmall').each(function() {
               this.style.display = 'none';
               this.disabled = 'disabled';
          });
});

There is now a Get-FileHash function which is very handy.

PS C:\> Get-FileHash C:\Users\Andris\Downloads\Contoso8_1_ENT.iso -Algorithm SHA384 | Format-List

Algorithm : SHA384
Hash      : 20AB1C2EE19FC96A7C66E33917D191A24E3CE9DAC99DB7C786ACCE31E559144FEAFC695C58E508E2EBBC9D3C96F21FA3
Path      : C:\Users\Andris\Downloads\Contoso8_1_ENT.iso

Just change SHA384 to MD5.

The example is from the official documentation of PowerShell 5.1. The documentation has more examples.

This question is a bit old, but for those still arriving here now and using react-router 4.3 it's a bug and got fixed in the beta version 4.4.0. Just upgrade your react-router to version +4.4.0. Be aware that it's a beta version at this moment.

On a Scientific Linux 6.7 system, the man page on rsync says:

--ignore-times          don't skip files that match size and time

I have two files with identical contents, but with different creation dates:

[root@windstorm ~]# ls -ls /tmp/master/usercron /tmp/new/usercron
4 -rwxrwx--- 1 root root 1595 Feb 15 03:45 /tmp/master/usercron
4 -rwxrwx--- 1 root root 1595 Feb 16 04:52 /tmp/new/usercron

[root@windstorm ~]# diff /tmp/master/usercron /tmp/new/usercron
[root@windstorm ~]# md5sum /tmp/master/usercron /tmp/new/usercron
368165347b09204ce25e2fa0f61f3bbd  /tmp/master/usercron
368165347b09204ce25e2fa0f61f3bbd  /tmp/new/usercron

With --size-only, the two files are regarded the same:

[root@windstorm ~]# rsync -v --size-only -n  /tmp/new/usercron /tmp/master/usercron

sent 29 bytes  received 12 bytes  82.00 bytes/sec
total size is 1595  speedup is 38.90 (DRY RUN)

With --ignore-times, the two files are regarded different:

[root@windstorm ~]# rsync -v --ignore-times -n  /tmp/new/usercron /tmp/master/usercron
usercron

sent 32 bytes  received 15 bytes  94.00 bytes/sec
total size is 1595  speedup is 33.94 (DRY RUN)

So it does not looks like --ignore-times has any effect at all.

To create a symbolic link /soft link, use:

ln -s {source-filename} {symbolic-filename}

e.g.:

ln -s file1 link1

Very much agreed with @Patrik M, but the thing with Arrays.toString is that it includes "[" and "]" and "," in the output. So I'll simply use a regex to remove them from outout like this

String strOfInts = Arrays.toString(intArray).replaceAll("\\[|\\]|,|\\s", "");

and now you have a String which can be parsed back to java.lang.Number, for example,

long veryLongNumber = Long.parseLong(intStr);

Or you can use the java 8 streams, if you hate regex,

String strOfInts = Arrays
            .stream(intArray)
            .mapToObj(String::valueOf)
            .reduce((a, b) -> a.concat(",").concat(b))
            .get();

Example using std::string find method:

#include <iostream>
#include <string>

int main (){
    std::string str ("There are two needles in this haystack with needles.");
    std::string str2 ("needle");

    size_t found = str.find(str2);
    if(found!=std::string::npos){ 
        std::cout << "first 'needle' found at: " << found << '\n';
    }

    return 0;
}

Result:

first 'needle' found at: 14.

Please don't let the question of "which one is faster" be the deciding factor of which to use. Chances are you're never going to care that much, and besides, programmer reading time is far more expensive than machine time.

Use whichever makes most sense to the human reading the code.

The short answer is no. The long answer is yes. :-)

Markdown was designed to allow people to write simple, readable text that could be easily converted to a simple HTML markup. It doesn't really do document layout. For example, there's no real way to align an image to the right or left. As to your question, there's no markdown command to include a single link from one file to another in any version of markdown (so far as I know).

The closest you could come to this functionality is Pandoc. Pandoc allows you to merge files as a part of the transformation, which allows you to easily render multiple files into a single output. For example, if you were creating a book, then you could have chapters like this:

01_preface.md
02_introduction.md
03_why_markdown_is_useful.md
04_limitations_of_markdown.md
05_conclusions.md

You can merge them by doing executing this command within the same directory:

pandoc *.md > markdown_book.html

Since pandoc will merge all the files prior to doing the translation, you can include your links in the last file like this:

01_preface.md
02_introduction.md
03_why_markdown_is_useful.md
04_limitations_of_markdown.md
05_conclusions.md
06_links.md

So part of your 01_preface.md could look like this:

I always wanted to write a book with [markdown][mkdnlink].

And part of your 02_introduction.md could look like this:

Let's start digging into [the best text-based syntax][mkdnlink] available.

As long as your last file includes the line:

[mkdnlink]: http://daringfireball.net/projects/markdown

...the same command used before will perform the merge and conversion while including that link throughout. Just make sure you leave a blank line or two at the beginning of that file. The pandoc documentation says that it adds a blank line between files that are merged this way, but this didn't work for me without the blank line.

In current version of Jekyll, it defaults to http://127.0.0.1:4000/.
This is good, if you are connected to a network but do not want anyone else to access your application.

However it may happen that you want to see how your application runs on a mobile or from some other laptop/computer.

In that case, you can use

jekyll serve --host 0.0.0.0

This binds your application to the host & next use following to connect to it from some other host

http://host's IP adress/4000 

this.WindowState = FormWindowState.Minimized;

An alternative to overcome this is running the change detector manually.

You first inject the ChangeDetectorRef:

constructor(private changeDetector : ChangeDetectorRef) {}

Then you call it after updating the variable that controls the *ngIf

show() {
        this.display = true;
        this.changeDetector.detectChanges();
    }

In case anyone is still looking for this, this solved the problem for us:

IIS 7 was difficult for figuring out why i was getting the 401 - Unauthorized: Access is denied due to invalid credentials... until i did this...

1. Open IIS and select the website that is causing the 401
2. Open the "Authentication" property under the "IIS" header
3. Click the "Windows Authentication" item and click "Providers"
4. For me the issue was that Negotiate was above NTLM. I assume that there was some kind of handshake going on behind the scenes, but i was never really authenticated. I moved the NTLM to the top most spot, and BAM that fixed it.

Here is the link where this was found.

From the RFC (3023), under section 3, XML Media Types:

If an XML document -- that is, the unprocessed, source XML document -- is readable by casual users, text/xml is preferable to application/xml. MIME user agents (and web user agents) that do not have explicit support for text/xml will treat it as text/plain, for example, by displaying the XML MIME entity as plain text. Application/xml is preferable when the XML MIME entity is unreadable by casual users.

(emphasis mine)

We recently ran into a similar issue and was unable to find anything obvious as the cause. There turned out to be a control character in our string but when we outputted that string to the browser that character was not visible unless we copied the text into an IDE.

We managed to solve our problem thanks to this post and this:

preg_replace('/[\x00-\x1F\x7F]/', '', $input);

Looks like you created a separate question. I was answering your other question How to change flat file source using foreach loop container in an SSIS package? with the same answer. Anyway, here it is again.

Create two string data type variables namely DirPath and FilePath. Set the value C:\backup\ to the variable DirPath. Do not set any value to the variable FilePath.

Select the variable FilePath and select F4 to view the properties. Set the EvaluateAsExpression property to True and set the Expression property as @[User::DirPath] + "Source" + (DT_STR, 4, 1252) DATEPART("yy" , GETDATE()) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , GETDATE()), 2) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , GETDATE()), 2)

You are using a very old version of curl. My guess is that you run into the bug described 6 years ago. Fix is to update your curl.

You can't rely on context menus because the user can deactivate it. Most websites want to use the feature to annoy the visitor.

This is more of an xpath question, but like this, assuming the context is the parent element:

<xsl:value-of select="name/@attribute1" />

The response headers in case of cors remain hidden. You need to add in response headers to direct the Angular to expose headers to javascript.

// From server response headers :
header("Access-Control-Allow-Methods: GET, POST, OPTIONS");
header("Access-Control-Allow-Headers: Origin, X-Requested-With, 
Content-Type, Accept, Authorization, X-Custom-header");
header("Access-Control-Expose-Headers: X-Custom-header");
header("X-Custom-header: $some data");

var data = res.headers.get('X-Custom-header');

You can use dijkstra's algorithm with negative edges not including negative cycle, but you must allow a vertex can be visited multiple times and that version will lose it's fast time complexity.

In that case practically I've seen it's better to use SPFA algorithm which have normal queue and can handle negative edges.

Use. <?php $con = mysqli_connect('localhost', 'username', 'password', 'database'); ?>

In PHP 7. You probably have PHP 7 in XAMPP. You now have two option: MySQLi and PDO.

The key checks for FAST REFRESH includes the following:

1) An Oracle materialized view log must be present for each base table.
2) The RowIDs of all the base tables must appear in the SELECT list of the MVIEW query definition.
3) If there are outer joins, unique constraints must be placed on the join columns of the inner table.

No 3 is easy to miss and worth highlighting here

Based on the previous answers I'm using the following utility methods in case anyone would like to use it.

    byte[] data;
    try {
        data = message.getBytes("UTF-8");
        String base64Sms = Base64.encodeToString(data, Base64.DEFAULT);
        return base64Sms;
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }

    return null;
}

/**

 * @return the decoded message
 */
public static String fromBase64(String message) {
    byte[] data = Base64.decode(message, Base64.DEFAULT);
    try {
        return new String(data, "UTF-8");
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }

    return null;

I would go through the packet capture and see if there are any records that I know I should be seeing to validate that the filter is working properly and to assuage any doubts.

That said, please try the following filter and see if you're getting the entries that you think you should be getting:

An abstract class is a class whose object cannot be created or a class which cannot be instantiated. An abstract method makes a class abstract. An abstract class needs to be inherited in order to override the methods that are declared in the abstract class. No restriction on access specifiers. An abstract class can have constructor and other concrete(non abstarct methods ) methods in them but interface cannot have.

An interface is a blueprint/template of methods.(eg. A house on a paper is given(interface house) and different architects will use their ideas to build it(the classes of architects implementing the house interface) . It is a collection of abstract methods , default methods , static methods , final variables and nested classes. All members will be either final or public , protected and private access specifiers are not allowed.No object creation is allowed. A class has to be made in order to use the implementing interface and also to override the abstract method declared in the interface. An interface is a good example of loose coupling(dynamic polymorphism/dynamic binding) An interface implements polymorphism and abstraction.It tells what to do but how to do is defined by the implementing class. For Eg. There's a car company and it wants that some features to be same for all the car it is manufacturing so for that the company would be making an interface vehicle which will have those features and different classes of car(like Maruti Suzkhi , Maruti 800) will override those features(functions).

Why interface when we already have abstract class? Java supports only multilevel and hierarchal inheritance but with the help of interface we can implement multiple inheritance.

Under advanced settings of firefox you should be able to set the encryption. By default SSL3.0 and TLS1.0 should be checked, so if firefox is trying to create ssl 3.0 connectons try unchecking the ssl 3.0s setting.

if that doesn't work, try searching the about:config page for "ssl2" My Firefox has settings with ssl2 set to false by default...

It is likely you will have to pull the text file into memory and then do the replacements. You will then have to overwrite the file using the method you clearly know about. So you would first:

// Read lines from source file.
string[] arr = File.ReadAllLines(file);

YOu can then loop through and replace the text in the array.

var writer = new StreamWriter(GetFileName(baseFolder, prefix, num));
for (int i = 0; i < arr.Length; i++)
{
    string line = arr[i];
    line.Replace("match", "new value");
    writer.WriteLine(line);
}

this method gives you some control on the manipulations you can do. Or, you can merely do the replace in one line

File.WriteAllText("test.txt", text.Replace("match", "new value"));

I hope this helps.

SELECT CREATED FROM USER_OBJECTS WHERE OBJECT_NAME='<<YOUR TABLE NAME>>'

yes, in a limited sense.

public class DataSet : System.Data.DataSet
{
    public static void SpecialMethod() { }
}

This works but Console doesn't because it's static.

public static class Console
{       
    public static void WriteLine(String x)
    { System.Console.WriteLine(x); }

    public static void WriteBlueLine(String x)
    {
        System.Console.ForegroundColor = ConsoleColor.Blue;
        System.Console.Write(.x);           
    }
}

This works because as long as it's not on the same namespace. The problem is that you have to write a proxy static method for every method that System.Console have. It's not necessarily a bad thing as you can add something like this:

    public static void WriteLine(String x)
    { System.Console.WriteLine(x.Replace("Fck","****")); }

or

 public static void WriteLine(String x)
    {
        System.Console.ForegroundColor = ConsoleColor.Blue;
        System.Console.WriteLine(x); 
    }

The way it works is that you hook something into the standard WriteLine. It could be a line count or bad word filter or whatever. Whenever you just specify Console in your namespace say WebProject1 and import the namespace System, WebProject1.Console will be chosen over System.Console as default for those classes in namespace WebProject1. So this code will turn all the Console.WriteLine calls into blue insofar as you never specified System.Console.WriteLine.

Here is a working version of the "build defs". This is similar to my previous answer but I figured out the build month. (You just can't compute build month in a #if statement, but you can use a ternary expression that will be compiled down to a constant.)

Also, according to the documentation, if the compiler cannot get the time of day it will give you question marks for these strings. So I added tests for this case, and made the various macros return an obviously wrong value (99) if this happens.

However, when I try to use those macros with your stringizing macro, it stringizes the literal expression! I don't know of any way to get the compiler to reduce the expression to a literal integer value and then stringize.

Also, if you try to statically initialize an array of values using these macros, the compiler complains with an error: initializer element is not constant message. So you cannot do what you want with these macros.

At this point I'm thinking that your best bet is the Python script that just generates a new include file for you. You can pre-compute anything you want in any format you want. If you don't want Python we can write an AWK script or even a C program.

I see that you tagged this with Ubuntu. Most likely the MySQL driver (and possibly MySQL) is not installed. Assuming you have SSH or terminal access and sudo permissions, log into the server and run this:

sudo apt-get install mysql-server mysql-client php5-mysql

If the MySQL packages or the php5-mysql package are already installed, this will update them.

UPDATE

Since this answer still gets the occasional click I am going to update it to include PHP 7. PHP 7 requires a different package for MySQL so you will want to use a different argument for the apt-get command.

# Replace 7.4 with your version of PHP
sudo apt-get install mysql-server mysql-common php7.4 php7.4-mysql

And importantly, mysql_connect() has been deprecated since PHP v5.5.0. Refer the official documentation here: PHP: mysql_connect()

I've seen where you can do something like this, assuming "NewWindow.cshtml" is in your "Home" folder:

string url = "/Home/NewWindow";
return JavaScript(string.Format("window.open('{0}', '_blank', 'left=100,top=100,width=500,height=500,toolbar=no,resizable=no,scrollable=yes');", url));

or

return Content("/Home/NewWindow");

If you just want to open views in tabs, you could use JavaScript click events to render your partial views. This would be your controller method for NewWindow.cshtml:

public ActionResult DisplayNewWindow(NewWindowModel nwm) {
    // build model list based on its properties & values
    nwm.Name = "John Doe";
    nwm.Address = "123 Main Street";
    return PartialView("NewWindow", nwm);
}

Your markup on your page this is calling it would go like this:

<input type="button" id="btnNewWin" value="Open Window" />
<div id="newWinResults" />

And the JavaScript (requires jQuery):

var url = '@Url.Action("NewWindow", "Home")';
$('btnNewWin').on('click', function() {
    var model = "{ 'Name': 'Jane Doe', 'Address': '555 Main Street' }"; // you must build your JSON you intend to pass into the "NewWindowModel" manually
    $('#newWinResults').load(url, model); // may need to do JSON.stringify(model)
});

Note that this JSON would overwrite what is in that C# function above. I had it there for demonstration purposes on how you could hard-code values, only.

(Adapted from Rendering partial view on button click in ASP.NET MVC)

This just happened to me in a string assignment using double quotes. I was missing a closing curly on a POST variable...

"for {$_POST['txtName'] on $date";

should have been

"for {$_POST['txtName']} on $date";

I can't explain why. I mean, I see the error that would break the code but I don't see why it references a class error.

break is what you're looking for:

while (true) {
    if (obj == null) break;
}

alternatively, restructure your loop:

while (obj != null) {
    // do stuff
}

or:

do {
    // do stuff
} while (obj != null);

In the opening tag of your form, set an action attribute like so:

<form id="contactForm" action="#">

You can use the -f operator

$a = "{0:D}" -f (get-date)
$a = "{0:dddd}" -f (get-date)

For anyone experiencing this in angular 9+

This issue can also be experienced if you do not declare or import the component that declares your component.

Lets consider a situation where you intend to use ng-select but you forget to import it Angular will throw the error 'No value accessor...'

I have reproduced this error in the Below stackblitz demo.

You can use this

string x = "ABCGH"

char[] charX = x.ToCharArray();

Array.Sort(charX);

This will sort your string.

Short answer

 new Map([...map].sort((a, b) => 
   // Some sort function comparing keys with a[0] b[0] or values with a[1] b[1]
 ))

If you're expecting strings: As normal for .sort you need to return -1 if lower and 0 if equal; for strings, the recommended way is using .localeCompare() which does this correctly and automatically handles awkward characters like ä where the position varies by user locale.

So here's how to sort a map by string keys:

 new Map([...map].sort((a, b) => String(a[0]).localeCompare(b[0])))

...and by string values:

 new Map([...map].sort((a, b) => String(a[1]).localeCompare(b[1])))

In detail with examples

tldr: ...map.entries() is redundant, just ...map is fine; and a lazy .sort() without passing a sort function risks weird edge case bugs caused by string coercion.

The .entries() in [...map.entries()] (suggested in many answers) is redundant, probably adding an extra iteration of the map unless the JS engine optimises that away for you.

In the simple test case, you can do what the question asks for with:

new Map([...map].sort())

...which, if the keys are all strings, compares squashed and coerced comma-joined key-value strings like '2-1,foo' and '0-1,[object Object]', returning a new Map with the new insertion order:

Note: if you see only {} in SO's console output, look in your real browser console

const map = new Map([
  ['2-1', 'foo'],
  ['0-1', { bar: 'bar' }],
  ['3-5', () => 'fuz'],
  ['3-2', [ 'baz' ]]
])

console.log(new Map([...map].sort()))

HOWEVER, it's not a good practice to rely on coercion and stringification like this. You can get surprises like:

const map = new Map([
  ['2', '3,buh?'],
  ['2,1', 'foo'],
  ['0,1', { bar: 'bar' }],
  ['3,5', () => 'fuz'],
  ['3,2', [ 'baz' ]],
])

// Compares '2,3,buh?' with '2,1,foo'
// Therefore sorts ['2', '3,buh?'] ******AFTER****** ['2,1', 'foo']
console.log('Buh?', new Map([...map].sort()))

// Let's see exactly what each iteration is using as its comparator
for (const iteration of map) {
  console.log(iteration.toString())
}

Bugs like this are really hard to debug - don't risk it!

If you want to sort on keys or values, it's best to access them explicitly with a[0] and b[0] in the sort function, like this. Note that we should return -1 and 1 for before and after, not false or 0 as with raw a[0] > b[0] because that is treated as equals:

const map = new Map([
  ['2,1', 'this is overwritten'],
  ['2,1', '0,1'],
  ['0,1', '2,1'],
  ['2,2', '3,5'],
  ['3,5', '2,1'],
  ['2', ',9,9']
])

const sortStringKeys = (a, b) => String(a[0]).localeCompare(b[0])
const sortStringValues = (a, b) => String(a[1]).localeCompare(b[1])

console.log('By keys:', new Map([...map].sort(sortStringKeys)))
console.log('By values:', new Map([...map].sort(sortStringValues)))

The recommended idiom to sort lists of values using expensive-to-compute keys is to the so-called "decorated pattern". It consists simply in building a list of (key, value) tuples from the original list, and sort that list. Then it is trivial to eliminate the keys and get the list of sorted values:

>>> original_list = ['a', 'b', 'A', 'B']
>>> decorated = [(s.lower(), s) for s in original_list]
>>> decorated.sort()
>>> sorted_list = [s[1] for s in decorated]
>>> sorted_list
['A', 'a', 'B', 'b']

Or if you like one-liners:

>>> sorted_list = [s[1] for s in sorted((s.lower(), s) for s in original_list)]
>>> sorted_list
['A', 'a', 'B', 'b']

If you really worry about the cost of calling lower(), you can just store tuples of (lowered string, original string) everywhere. Tuples are the cheapest kind of containers in Python, they are also hashable so they can be used as dictionary keys, set members, etc.

Try below code,

Intent intent = new Intent(ManageProfileActivity.this, LoginActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|
                Intent.FLAG_ACTIVITY_CLEAR_TASK| 
                Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

For me save_queries option was turned off so,

$this->db->save_queries = TRUE; //Turn ON save_queries for temporary use.
$str = $this->db->last_query();
echo $str;

You may take a look at this answer to an identical question (as I understand): https://stackoverflow.com/a/1478553 The link posted there explains the problem.

For quick solving your problem you should try to code something like this:

ImplementingClass::virtualFunctionToImplement(){...} It helped me a lot.

If it's simply about inserting and resizing a picture, try the code below.

For the specific question you asked, the property TopLeftCell returns the range object related to the cell where the top left corner is parked. To place a new image at a specific place, I recommend creating an image at the "right" place and registering its top and left properties values of the dummy onto double variables.

Insert your Pic assigned to a variable to easily change its name. The Shape Object will have that same name as the Picture Object.

Sub Insert_Pic_From_File(PicPath as string, wsDestination as worksheet)
    Dim Pic As Picture, Shp as Shape
    Set Pic = wsDestination.Pictures.Insert(FilePath)
    Pic.Name = "myPicture"
    'Strongly recommend using a FileSystemObject.FileExists method to check if the path is good before executing the previous command
    Set Shp = wsDestination.Shapes("myPicture")
    With Shp
        .Height = 100
        .Width = 75
        .LockAspectRatio = msoTrue  'Put this later so that changing height doesn't change width and vice-versa)
        .Placement = 1
        .Top = 100
        .Left = 100
    End with
End Sub

Good luck!

The problem exists in old versions on the iOS. in the latest, the right-to-left works well. What I did, is as follows:

first I check the iOS version:

Than:

// set RTL on the start on each line (except the first)  
myUITextView.text = [myUITextView.text stringByReplacingOccurrencesOfString:@"\n"

for($i = 0 ; $i < count($arr)  ; $i++ )
{
    $tmpArr[$arr[$i]['id']] = $arr[$i]['id'];
}
$vmpArr = array_keys($tmpArr);

If you want the content string and this string does not have parameters you can use

    String line = null;
    BufferedReader reader = request.getReader();
    while ((line = reader.readLine()) != null){
        System.out.println(line);
    }

It's not as simple as just omitting the return keyword. In Scala, if there is no return then the last expression is taken to be the return value. So, if the last expression is what you want to return, then you can omit the return keyword. But if what you want to return is not the last expression, then Scala will not know that you wanted to return it.

An example:

def f() = {
  if (something)
    "A"
  else
    "B"
}

Here the last expression of the function f is an if/else expression that evaluates to a String. Since there is no explicit return marked, Scala will infer that you wanted to return the result of this if/else expression: a String.

Now, if we add something after the if/else expression:

def f() = {
  if (something)
    "A"
  else
    "B"

  if (somethingElse)
    1
  else

Now the last expression is an if/else expression that evaluates to an Int. So the return type of f will be Int. If we really wanted it to return the String, then we're in trouble because Scala has no idea that that's what we intended. Thus, we have to fix it by either storing the String to a variable and returning it after the second if/else expression, or by changing the order so that the String part happens last.

Finally, we can avoid the return keyword even with a nested if-else expression like yours:

def f() = {
  if(somethingFirst) {
    if (something)      // Last expression of `if` returns a String
     "A"
    else
     "B"
  }
  else {
    if (somethingElse)
      1
    else
      2

    "C"                // Last expression of `else` returns a String
  }

}

The no-op command in shell is : (colon).

if [ "$a" -ge 10 ]
then
    :
elif [ "$a" -le 5 ]
then
    echo "1"
else
    echo "2"
fi

From the bash manual:

: (a colon)
Do nothing beyond expanding arguments and performing redirections. The return status is zero.
