Without really knowing the complexity of the setup, I like the sudo route. First, you must configure sudo to permit your webserver to sudo run the given command as root. Then, you need to have the script that the webserver shell_exec's(testscript) run the command with sudo.

For A Debian box with Apache and sudo:

1. Configure sudo:

   • As root, run the following to edit a new/dedicated configuration file for sudo:

     visudo -f /etc/sudoers.d/Webserver
     

     (or whatever you want to call your file in /etc/sudoers.d/)

   • Add the following to the file:

     www-data ALL = (root) NOPASSWD: <executable_file_path>
     

     where <executable_file_path> is the command that you need to be able to run as root with the full path in its name(say /bin/chown for the chown executable). If the executable will be run with the same arguments every time, you can add its arguments right after the executable file's name to further restrict its use.

     For example, say we always want to copy the same file in the /root/ directory, we would write the following:

     www-data ALL = (root) NOPASSWD: /bin/cp /root/test1 /root/test2
     

2. Modify the script(testscript):

   Edit your script such that sudo appears before the command that requires root privileges(say sudo /bin/chown ... or sudo /bin/cp /root/test1 /root/test2). Make sure that the arguments specified in the sudo configuration file exactly match the arguments used with the executable in this file. So, for our example above, we would have the following in the script:

   sudo /bin/cp /root/test1 /root/test2
   

If you are still getting permission denied, the script file and it's parent directories' permissions may not allow the webserver to execute the script itself. Thus, you need to move the script to a more appropriate directory and/or change the script and parent directory's permissions to allow execution by www-data(user or group), which is beyond the scope of this tutorial.

Keep in mind:

When configuring sudo, the objective is to permit the command in it's most restricted form. For example, instead of permitting the general use of the cp command, you only allow the cp command if the arguments are, say, /root/test1 /root/test2. This means that cp's arguments(and cp's functionality cannot be altered).

simple solution:

 Mymodel::query()->delete();

Considering filter:expression is a Microsoft extension to CSS, so it will only work in Internet Explorer. If you want to grey it out, I would recommend that you set it's opacity to 50% using a bit of javascript.

http://lyxus.net/mv would be a good place to start, because it discusses an opacity script that works with Firefox, Safari, KHTML, Internet Explorer and CSS3 capable browsers.

You might also want to give it a grey border.

It almost never makes intuitive sense to have two inputs next to each other without labels. Here is a solution with labels mixed in, which also works quite well with just a minor modification to existing Bootstrap styles.

Preview:

HTML:

<div class="input-group">
  <span class="input-group-addon">Between</span>
  <input type="text" class="form-control" placeholder="Type something..." />
  <span class="input-group-addon" style="border-left: 0; border-right: 0;">and</span>
  <input type="text" class="form-control" placeholder="Type something..." />
</div>

CSS:

.input-group-addon {
  border-left-width: 0;
  border-right-width: 0;
}
.input-group-addon:first-child {
  border-left-width: 1px;
}
.input-group-addon:last-child {
  border-right-width: 1px;
}

Use Convert.TryFromBase64String from C# 7.2

public static bool IsBase64String(string base64)
{
   Span<byte> buffer = new Span<byte>(new byte[base64.Length]);
   return Convert.TryFromBase64String(base64, buffer , out int bytesParsed);
}

Sorry, but Eduardos solution did not work for me. At the end, I realized that disabled datepicker is just a read-only textbox. So you should make it read only and destroy the datepicker. Field will be sent to server upon submit.

Here is a bit generalized code that takes multiple textboxes and makes them read only. It will strip off the datepickers as well.

fields.attr("readonly", "readonly");
fields.each(function(idx, fld) {
    if($(fld).hasClass('hasDatepicker'))
    {
        $(fld).datepicker("destroy");
    }
});

Using printf you can do

printf("Here are the first 8 chars: %.8s\n", "A string that is more than 8 chars");

If you're using C++, you can achieve the same result using the STL:

using namespace std; // for clarity
string s("A string that is more than 8 chars");
cout << "Here are the first 8 chars: ";
copy(s.begin(), s.begin() + 8, ostream_iterator<char>(cout));
cout << endl;

Or, less efficiently:

cout << "Here are the first 8 chars: " <<
        string(s.begin(), s.begin() + 8) << endl;

I know, it is long ago, but since the easiest answer was not yet posted I will do so for other user that might step by.

Just move the var inside the "name" block:

- name: Download apache
  vars:
    url: czxcxz
  shell: wget {{url}} 

Also the visual studio add-in ghost doc will attempt to create and fill-in the header comments from your function name.

You can use VBA to export an Access database table as a Worksheet in an Excel Workbook.

To obtain the path of the Access database, use the CurrentProject.Path property.

To name the Excel Workbook file with the current date, use the Format(Date, "yyyyMMdd") method.

Finally, to export the table as a Worksheet, use the DoCmd.TransferSpreadsheet method.

Example:

Dim outputFileName As String
outputFileName = CurrentProject.Path & "\Export_" & Format(Date, "yyyyMMdd") & ".xls"
DoCmd.TransferSpreadsheet acExport, acSpreadsheetTypeExcel9, "Table1", outputFileName , True
DoCmd.TransferSpreadsheet acExport, acSpreadsheetTypeExcel9, "Table2", outputFileName , True

This will output both Table1 and Table2 into the same Workbook.

HTH

I found this version most suitable for all cases. It doesn't remove all whitespaces.

For example "a (test) b" -> "a b"

"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, " ").trim(); "Hello, this is (example) Mike ".replace(/ *\([^)]*\) */g, " ").trim();

npm start runs a script that the app maker built for easy starting of the app npm install installs all the packages in package.json

run npm install first

then run npm start

You can also set the environment variable to

CUDA_VISIBLE_DEVICES=""

without having to modify the source code.

For the sake of proper Javascript

HTMLTextAreaElement.prototype.insertAtCaret = function (text) {
  text = text || '';
  if (document.selection) {
    // IE
    this.focus();
    var sel = document.selection.createRange();
    sel.text = text;
  } else if (this.selectionStart || this.selectionStart === 0) {
    // Others
    var startPos = this.selectionStart;
    var endPos = this.selectionEnd;
    this.value = this.value.substring(0, startPos) +
      text +
      this.value.substring(endPos, this.value.length);
    this.selectionStart = startPos + text.length;
    this.selectionEnd = startPos + text.length;
  } else {
    this.value += text;
  }
};

Open the project you want to add it.

Right click on the name. Then select, add in the active project. Then the cpp file will get its link to cbp.

There is the index method, i = array.index(value), but I don't think you can specify a custom comparison operator. It wouldn't be hard to write your own function to do so, though:

def custom_index(array, compare_function):
    for i, v in enumerate(array):
        if compare_function(v):
            return i

Maintain a set and remove a randomly picked-up element (with choice) until the list is empty:

s = set(range(1, 6))
import random

while len(s) > 0:
  s.remove(random.choice(list(s)))
  print(s)

Three runs give three different answers:

>>>
set([1, 3, 4, 5])
set([3, 4, 5])

set([2, 3, 5])
set([2, 3])

    Sleep(milliseconds);
#elif _POSIX_C_SOURCE >= 199309L
    struct timespec ts;
    ts.tv_sec = milliseconds / 1000;
    ts.tv_nsec = (milliseconds % 1000) * 1000000;
    nanosleep(&ts, NULL);

Place the Image in the folder drawable. drawable folder is in res. drawable have 5 variants drawable-hdpi drawable-ldpi drawable-mdpi drawable-xhdpi drawable-xxhdpi

You can also search the Visual Studio project files for the XML tag RequiredTargetFramework. This tag seems to exist on .NET 3.5 and higher.

For example: <RequiredTargetFramework>3.5</RequiredTargetFramework>

Scala lists are immutable by default. You cannot "add" an element, but you can form a new list by appending the new element in front. Since it is a new list, you need to reassign the reference (so you can't use a val).

var dm  = List[String]()
var dk = List[Map[String,AnyRef]]()

.....

dm = "text" :: dm
dk = Map(1 -> "ok") :: dk

The operator :: creates the new list. You can also use the shorter syntax:

dm ::= "text" 
dk ::= Map(1 -> "ok")

NB: In scala don't use the type Object but Any, AnyRef or AnyVal.

We had the same issue with our Azure DevOps repositories after our domain changed, i.e. from @xy.com to @xyz.com. To fix this issue, we generated a fresh personal access token with the following permissions:

Code: read & write Packaging: read

Then we opened the Windows Credential Manager, added a new generic windows credential with the following details:

Internet or network address: "git:{projectname}@dev.azure.com/{projectname}" - alternatively you should use your git repository name here.
User name: "Personal Access Token"
Password: {The generated Personal Access Token}

Afterwards all our git operations were working again. Hope this helps someone else!

Edit, since i misunderstood the question:

Just put the Helper class in __init__.py. Thats perfectly pythonic. It just feels strange coming from languages like Java.

One of the benefit of using the resource file is accessing the resources by names, so the image can change, the image name can change, as long as the resource is kept up to date correct image will show up.

Here is a cleaner approach to accomplish this: Assuming Resources.resx is in 'UI.Images' namespace, add the namespace reference in your xaml like this:

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:UI="clr-namespace:UI.Images" 

Set your Image source like this:

<Image Source={Binding {x:Static UI:Resources.Search}} /> where 'Search' is name of the resource.

GROUP BY r.name

Oracle

I recommend reading about string aggregation/concatentation in Oracle.

Use Convert.ToInt32 from mscorlib as in

decimal value = 3.14m;
int n = Convert.ToInt32(value);

See MSDN. You can also use Decimal.ToInt32. Again, see MSDN. Finally, you can do a direct cast as in

decimal value = 3.14m;
int n = (int) value;

which uses the explicit cast operator. See MSDN.

Yes you can handle with the catch operator like this and show alert as you want but firstly you have to import Rxjs for the same like this way

import {Observable} from 'rxjs/Rx';

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status === 500) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 400) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 409) {
                    return Observable.throw(new Error(error.status));
                }
                else if (error.status === 406) {
                    return Observable.throw(new Error(error.status));
                }
            });
    }

also you can handel error (with err block) that is throw by catch block while .map function,

like this -

...
.subscribe(res=>{....}
           err => {//handel here});

Update

as required for any status without checking particluar one you can try this: -

return this.http.request(new Request(this.requestoptions))
            .map((res: Response) => {
                if (res) {
                    if (res.status === 201) {
                        return [{ status: res.status, json: res }]
                    }
                    else if (res.status === 200) {
                        return [{ status: res.status, json: res }]
                    }
                }
            }).catch((error: any) => {
                if (error.status < 400 ||  error.status ===500) {
                    return Observable.throw(new Error(error.status));
                }
            })
            .subscribe(res => {...},
                       err => {console.log(err)} );

(There are good answers above regarding the SQL nature of your question, but this may also be relevant if you are new to PHP.)

Perhaps it is important to mention that PHP handles single and double quoted strings differently...

Single-quoted strings are 'literals' and are pretty much WYSIWYG strings. Double-quoted strings are interpreted by PHP for possible variable-substitution (backticks in PHP are not exactly strings; they execute a command in the shell and return the result).

Examples:

$foo = "bar";
echo 'there is a $foo'; // There is a $foo
echo "there is a $foo"; // There is a bar
echo `ls -l`; // ... a directory list

You have two ways to fix this. The preferred way is to use:

string answer;

(instead of char). The other possible way to fix it is:

if (answer == 'y') ...

(note single quotes instead of double, representing a char constant).

Lombok Issue #78 references this page https://www.donneo.de/2015/09/16/lomboks-builder-annotation-and-inheritance/ with this lovely explanation:

@AllArgsConstructor 
public class Parent {   
     private String a; 
}

public class Child extends Parent {
  private String b;

  @Builder
  public Child(String a, String b){
    super(a);
    this.b = b;   
  } 
} 

As a result you can then use the generated builder like this:

Child.builder().a("testA").b("testB").build(); 

The official documentation explains this, but it doesn’t explicitly point out that you can facilitate it in this way.

I also found this works nicely with Spring Data JPA.

$.each($('input[type=number]'),function(){
  alert($(this).val());
});

This will alert the value of input type number fields

It seems like the other answers here all misunderstood your question. If I understand correctly, you want to make requests to localhost:6379 (the default for redis) and have them be forwarded, automatically, to the same port on your redis container.

https://unix.stackexchange.com/a/101906/38639 helped me get to the right answer.

First, you'll need to install the nc command on your image. On CentOS, this package is called nmap-ncat, so in the example below, just replace this with the appropriate package if you are using a different OS as your base image.

Next, you'll need to tell it to run a certain command each time the container boots up. You can do this using CMD.

# Add this to your Dockerfile
RUN yum install -y --setopt=skip_missing_names_on_install=False nmap-ncat
COPY cmd.sh /usr/local/bin/cmd.sh
RUN chmod +x /usr/local/bin/cmd.sh
CMD ["/usr/local/bin/cmd.sh"]

Finally, we'll need to set up port-forwarding in cmd.sh. I found that nc, even with the -l and -k options, will occasionally terminate when a request is completed, so I'm using a while-loop to ensure that it's always running.

# cmd.sh
#! /usr/bin/env bash

while nc -l -p 6379 -k -c "nc redis 6379" || true; do true; done &

tail -f /dev/null # Or any other command that never exits

A vector is a container with full ownership of it's elements. One vector cannot hold a partial view of another, even a const-view. That's the root cause here.

If you need that, make your own container that has views with weak_ptr's to the data, or look at ranges. Pair of iterators (even pointers work well as iterators into a vector) or, even better, boost::iterator_range that work pretty seamlessly.

It depends on the templatability of your code. Use std::pair if you need to hide the code in a cpp.

The reason you are getting the DECLARE error from your dynamic statement is because dynamic statements are handled in separate batches, which boils down to a matter of scope. While there may be a more formal definition of the scopes available in SQL Server, I've found it sufficient to generally keep the following three in mind, ordered from highest availability to lowest availability:

Global:

Objects that are available server-wide, such as temporary tables created with a double hash/pound sign ( ##GLOBALTABLE, however you like to call # ). Be very wary of global objects, just as you would with any application, SQL Server or otherwise; these types of things are generally best avoided altogether. What I'm essentially saying is to keep this scope in mind specifically as a reminder to stay out of it.

IF ( OBJECT_ID( 'tempdb.dbo.##GlobalTable' ) IS NULL )
BEGIN
    CREATE TABLE ##GlobalTable
    (
        Val             BIT
    );

    INSERT INTO ##GlobalTable ( Val )
    VALUES ( 1 );
END;
GO

-- This table may now be accessed by any connection in any database,
-- assuming the caller has sufficient privileges to do so, of course.

Session:

Objects which are reference locked to a specific spid. Off the top of my head, the only type of session object I can think of is a normal temporary table, defined like #Table. Being in session scope essentially means that after the batch ( terminated by GO ) completes, references to this object will continue to resolve successfully. These are technically accessible by other sessions, but it would be somewhat of a feat do to so programmatically as they get sort of randomized names in tempdb and accessing them is a bit of a pain in the ass anyway.

-- Start of session;
-- Start of batch;
IF ( OBJECT_ID( 'tempdb.dbo.#t_Test' ) IS NULL )
BEGIN
    CREATE TABLE #t_Test
    (
        Val     BIT
    );

    INSERT INTO #t_Test ( Val )
    VALUES ( 1 );
END;
GO 
-- End of batch;

-- Start of batch;
SELECT  *
FROM    #t_Test;
GO
-- End of batch;

Opening a new session ( a connection with a separate spid ), the second batch above would fail, as that session would be unable to resolve the #t_Test object name.

Batch:

Normal variables, such as your @value1 and @value2, are scoped only for the batch in which they are declared. Unlike #Temp tables, as soon as your query block hits a GO, those variables stop being available to the session. This is the scope level which is generating your error.

-- Start of session;
-- Start of batch;
DECLARE @test   BIT = 1;

PRINT @test;
GO
-- End of batch;

-- Start of batch;
PRINT @Test;  -- Msg 137, Level 15, State 2, Line 2
              -- Must declare the scalar variable "@Test".
GO
-- End of batch;

Okay, so what?

What is happening here with your dynamic statement is that the EXECUTE() command effectively evaluates as a separate batch, without breaking the batch you executed it from. EXECUTE() is good and all, but since the introduction of sp_executesql(), I use the former only in the most simple of instances ( explicitly, when there is very little "dynamic" element of my statements at all, primarily to "trick" otherwise unaccommodating DDL CREATE statements to run in the middle of other batches ). @AaronBertrand's answer above is similar and will be similar in performance to the following, leveraging the function of the optimizer when evaluating dynamic statements, but I thought it might be worthwhile to expand on the @param, well, parameter.

IF NOT EXISTS ( SELECT  1
                FROM    sys.objects
                WHERE   name = 'TblTest'
                    AND type = 'U' )
BEGIN
    --DROP TABLE dbo.TblTest;
    CREATE TABLE dbo.TblTest
    (
        ID      INTEGER,
        VALUE1  VARCHAR( 1 ),
        VALUE2  VARCHAR( 1 )
    );

    INSERT INTO dbo.TblTest ( ID, VALUE1, VALUE2 )
    VALUES ( 61, 'A', 'B' );
END;

SET NOCOUNT ON;

DECLARE @SQL    NVARCHAR( MAX ),
        @PRM    NVARCHAR( MAX ),
        @value1 VARCHAR( MAX ),
        @value2 VARCHAR( 200 ),
        @Table  VARCHAR( 32 ),
        @ID     INTEGER;

    SET @Table = 'TblTest';
    SET @ID = 61;

    SET @PRM = '
        @_ID        INTEGER,
        @_value1    VARCHAR( MAX ) OUT,
        @_value2    VARCHAR( 200 ) OUT';
    SET @SQL = '
        SELECT  @_value1 = VALUE1,
                @_value2 = VALUE2
        FROM    dbo.[' + REPLACE( @Table, '''', '' ) + ']
        WHERE   ID = @_ID;';

EXECUTE dbo.sp_executesql @statement = @SQL, @param = @PRM,
            @_ID = @ID, @_value1 = @value1 OUT, @_value2 = @value2 OUT;

PRINT @value1 + ' ' + @value2;

SET NOCOUNT OFF;

Why don't you just use the database diagram functionality built into SQL Server?

Use .map without return in simple way. Also start using let and const instead of var because let and const is more recommended

For anyone else having the issue - none of the answers provided worked for me.

My case may be different to others but I had Android Studio installed first which installs the SDK by default to: C:\Users\[user]\AppData\Local\Android\sdk. We then decided to use Xamarin for our projects, so Xamarin was installed and installed an additional SDK by default, located here: C:\Program Files (x86)\Android\android-sdk.

Changing Xamarin to match the same SDK path worked for me which I did in the registry (although through the VS settings I'd guess it's the same):

\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Android SDK Tools\Path

Change the path to match the Android Studio SDK path, close everything, start the VS Emulator, run Android Studio, ensure ADB integration is off and try. It worked for me.

I code in VB and was able to add the following line to my Global.asax.vb file inside of Application_Start

ServicePointManager.SecurityProtocol = CType(3072, SecurityProtocolType)    'TLS 1.2

It's all about the linkage.

The previous answers provided good explainations about extern.

But I want to add an important point.

You ask about extern in C++ not in C and I don't know why there is no answer mentioning about the case when extern comes with const in C++.

In C++, a const variable has internal linkage by default (not like C).

So this scenario will lead to linking error:

Source 1 :

const int global = 255; //wrong way to make a definition of global const variable in C++

Source 2 :

extern const int global; //declaration

It need to be like this:

Source 1 :

extern const int global = 255; //a definition of global const variable in C++

Source 2 :

extern const int global; //declaration

If you have several files or directories and want to compare non continuous commits, you could do this:

Make a temporary branch ("revision" in this example)

git checkout -b revision

Rewind to the first commit target

git reset --hard <commit_target>

Cherry picking on those commit interested

git cherry-pick <commit_interested> ...

Apply diff

git diff <commit-target>^

When you done

git branch -D revision

The previous answer from Andreas_D is good. I'm just going to add that wherever you are displaying the output there will be a font and a character encoding and it may not support some characters.

To work out whether it is Java or your display that is a problem, do this:

    for(int i=0;i<str.length();i++) {
        char ch = str.charAt(i);
        System.out.println(i+" : "+ch+" "+Integer.toHexString(ch)+((ch=='\ufffd') ? " Unknown character" : ""));
    }

Java will have mapped any characters it cannot understand to 0xfffd the official character for unknown characters. If you see a '?' in the output, but it is not mapped to 0xfffd, it is your display font or encoding that is the problem, not Java.

Ran into a similar issue the solution for me was to run fuser -k 'filename.db' on the file that had a lock associated with it.

Hope this helps!

As mentioned in one of the other answers, you can use putc(int c, FILE *stream), putchar(int c) or fputc(int c, FILE *stream) for this purpose.

What's important to note is that using any of the above functions is from some to signicantly faster than using any of the format-parsing functions like printf.

Using printf is like using a machine gun to fire one bullet.

In your example problem is passed table name pattern in getTables function of DatabaseMetaData.

Some database supports Uppercase identifier, some support lower case identifiers. For example oracle fetches the table name in upper case, while postgreSQL fetch it in lower case.

DatabaseMetaDeta provides a method to determine how the database stores identifiers, can be mixed case, uppercase, lowercase see:http://docs.oracle.com/javase/7/docs/api/java/sql/DatabaseMetaData.html#storesMixedCaseIdentifiers()

From below example, you can get all tables and view of providing table name pattern, if you want only tables then remove "VIEW" from TYPES array.

public class DBUtility {
    private static final String[] TYPES = {"TABLE", "VIEW"};
    public static void getTableMetadata(Connection jdbcConnection, String tableNamePattern, String schema, String catalog, boolean isQuoted) throws HibernateException {
            try {
                DatabaseMetaData meta = jdbcConnection.getMetaData();
                ResultSet rs = null;
                try {
                    if ( (isQuoted && meta.storesMixedCaseQuotedIdentifiers())) {
                        rs = meta.getTables(catalog, schema, tableNamePattern, TYPES);
                    } else if ( (isQuoted && meta.storesUpperCaseQuotedIdentifiers())
                        || (!isQuoted && meta.storesUpperCaseIdentifiers() )) {
                        rs = meta.getTables(
                                StringHelper.toUpperCase(catalog),
                                StringHelper.toUpperCase(schema),
                                StringHelper.toUpperCase(tableNamePattern),
                                TYPES
                            );
                    }
                    else if ( (isQuoted && meta.storesLowerCaseQuotedIdentifiers())
                            || (!isQuoted && meta.storesLowerCaseIdentifiers() )) {
                        rs = meta.getTables( 
                                StringHelper.toLowerCase( catalog ),
                                StringHelper.toLowerCase(schema),

                            );
                    }
                    else {
                        rs = meta.getTables(catalog, schema, tableNamePattern, TYPES);
                    }

                    while ( rs.next() ) {
                        String tableName = rs.getString("TABLE_NAME");
                        System.out.println("table = " + tableName);
                    }



                }
                finally {
                    if (rs!=null) rs.close();
                }
            }
            catch (SQLException sqlException) {
                // TODO 
                sqlException.printStackTrace();
            }

    }

            getTableMetadata(jdbcConnection, "tbl%", null, null, false);
        } catch (SQLException e) {

There's a great blog post on this here:

http://www.kylejlarson.com/blog/2011/fixed-elements-and-scrolling-divs-in-ios-5/

Along with a demo here:

http://www.kylejlarson.com/files/iosdemo/

In summary, you can use the following on a div containing your main content:

.scrollable {
    position: absolute;
    top: 50px;
    left: 0;
    right: 0;
    bottom: 0;
    overflow: scroll;
    -webkit-overflow-scrolling: touch;
}

The problem I think you're describing is when you try to scroll up within a div that is already at the top - it then scrolls up the page instead of up the div and causes a bounce effect at the top of the page. I think your question is asking how to get rid of this?

In order to fix this, the author suggests that you use ScrollFix to auto increase the height of scrollable divs.

It's also worth noting that you can use the following to prevent the user from scrolling up e.g. in a navigation element:

document.addEventListener('touchmove', function(event) {
   if(event.target.parentNode.className.indexOf('noBounce') != -1 
|| event.target.className.indexOf('noBounce') != -1 ) {
    event.preventDefault(); }
}, false);

Unfortunately there are still some issues with ScrollFix (e.g. when using form fields), but the issues list on ScrollFix is a good place to look for alternatives. Some alternative approaches are discussed in this issue.

Other alternatives, also mentioned in the blog post, are Scrollability and iScroll

This problem was created by a regression in a recent release. You can find the pull request that fixes this problem at https://github.com/facebook/react-native-fbsdk/pull/339

Postgres started on Linux/Unix. I suspect that reversing the slash with fix it.

\i somedir/script2.sql 

If you need to fully qualify something

\i c:/somedir/script2.sql

If that doesn't fix it, my next guess would be you need to escape the backslash.

\i somedir\\script2.sql

What is it?

WAI-ARIA stands for “Web Accessibility Initiative – Accessible Rich Internet Applications”. It is a set of attributes to help enhance the semantics of a web site or web application to help assistive technologies, such as screen readers for the blind, make sense of certain things that are not native to HTML. The information exposed can range from something as simple as telling a screen reader that activating a link or button just showed or hid more items, to widgets as complex as whole menu systems or hierarchical tree views.

This is achieved by applying roles and state attributes to HTML 4.01 or later markup that has no bearing on layout or browser functionality, but provides additional information for assistive technologies.

One corner stone of WAI-ARIA is the role attribute. It tells the browser to tell the assistive technology that the HTML element used is not actually what the element name suggests, but something else. While it originally is only a div element, this div element may be the container to a list of auto-complete items, in which case a role of “listbox” would be appropriate to use. Likewise, another div that is a child of that container div, and which contains a single option item, should then get a role of “option”. Two divs, but through the roles, totally different meaning. The roles are modeled after commonly used desktop application counterparts.

An exception to this are document landmark roles, which don’t change the actual meaning of the element in question, but provide information about this particular place in a document.

The second corner stone are WAI-ARIA states and properties. They define the state of certain native or WAI-ARIA elements such as if something is collapsed or expanded, a form element is required, something has a popup menu attached to it or the like. These are often dynamic and change their values throughout the lifecycle of a web application, and are usually manipulated via JavaScript.

What is it not?

WAI-ARIA is not intended to influence browser behavior. Unlike a real button element, for example, a div which you pour the role of “button” onto does not give you keyboard focusability, an automatic click handler when Space or Enter are being pressed on it, and other properties that are indiginous to a button. The browser itself does not know that a div with role of “button” is a button, only its accessibility API portion does.

As a consequence, this means that you absolutely have to implement keyboard navigation, focusability and other behavioural patterns known from desktop applications yourself. You can find some Advanced ARIA techniques Here.

When should I not use it?

Yes, that’s correct, this section comes first! Because the first rule of using WAI-ARIA is: Don’t use it unless you absolutely have to! The less WAI-ARIA you have, and the more you can count on using native HTML widgets, the better! There are some more rules to follow, you can check them out here.

In str's answer, value 'undefined' will be returned instead of the set default value if the property is undefined. This sometimes can cause bugs. The following will make sure the defaultVal will always be returned when either the property or the object is undefined.

const temp = {};
console.log(getSafe(()=>temp.prop, '0'));

function getSafe(fn, defaultVal) {
    try {
        if (fn() === undefined) {
            return defaultVal
        } else {
            return fn();
        }

    } catch (e) {
        return defaultVal;
    }
}

I tried using phyatt's AspectRatioPixmapLabel class, but experienced a few problems:

• Sometimes my app entered an infinite loop of resize events. I traced this back to the call of QLabel::setPixmap(...) inside the resizeEvent method, because QLabel actually calls updateGeometry inside setPixmap, which may trigger resize events...
• heightForWidth seemed to be ignored by the containing widget (a QScrollArea in my case) until I started setting a size policy for the label, explicitly calling policy.setHeightForWidth(true)
• I want the label to never grow more than the original pixmap size
• QLabel's implementation of minimumSizeHint() does some magic for labels containing text, but always resets the size policy to the default one, so I had to overwrite it

That said, here is my solution. I found that I could just use setScaledContents(true) and let QLabel handle the resizing. Of course, this depends on the containing widget / layout honoring the heightForWidth.

aspectratiopixmaplabel.h

#ifndef ASPECTRATIOPIXMAPLABEL_H
#define ASPECTRATIOPIXMAPLABEL_H

#include <QLabel>
#include <QPixmap>

class AspectRatioPixmapLabel : public QLabel
{
    Q_OBJECT
public:
    explicit AspectRatioPixmapLabel(const QPixmap &pixmap, QWidget *parent = 0);
    virtual int heightForWidth(int width) const;
    virtual bool hasHeightForWidth() { return true; }
    virtual QSize sizeHint() const { return pixmap()->size(); }
    virtual QSize minimumSizeHint() const { return QSize(0, 0); }
};

#endif // ASPECTRATIOPIXMAPLABEL_H

aspectratiopixmaplabel.cpp

#include "aspectratiopixmaplabel.h"

AspectRatioPixmapLabel::AspectRatioPixmapLabel(const QPixmap &pixmap, QWidget *parent) :
    QLabel(parent)
{
    QLabel::setPixmap(pixmap);
    setScaledContents(true);
    QSizePolicy policy(QSizePolicy::Maximum, QSizePolicy::Maximum);
    policy.setHeightForWidth(true);
    this->setSizePolicy(policy);
}

int AspectRatioPixmapLabel::heightForWidth(int width) const
{
    if (width > pixmap()->width()) {
        return pixmap()->height();
    } else {
        return ((qreal)pixmap()->height()*width)/pixmap()->width();
    }
}

Hope this will help someone.

-> open to keyboard shortcut

-> search for "workbench.action.togglePanelPosition"

-> assign your desired shortcut

I've assigned keybinding "cmd+`"

{
  "key": "cmd+`",
  "command": "workbench.action.togglePanelPosition"
}

now I can toggle the terminal by pressing "cmd + `"

For single-byte strings (e.g. US-ASCII, ISO 8859 family, etc.) use substr and for multi-byte strings (e.g. UTF-8, UTF-16, etc.) use mb_substr:

// singlebyte strings
$result = substr($myStr, 0, 5);
// multibyte strings
$result = mb_substr($myStr, 0, 5);

If you find that PIL has problems on some platforms, using a native image viewer may help.

img.save("tmp.png") #Save the image to a PNG file called tmp.png.

For MacOS:

import os
os.system("open tmp.png") #Will open in Preview.

For most GNU/Linux systems with X.Org and a desktop environment:

import os
os.system("xdg-open tmp.png")

For Windows:

import os
os.system("powershell -c tmp.png")

For a more flexible and lazy solution, you could match all properties of the objects. Most of the time, this should get you the behavior you want, and you can always be more specific when it doesn't. Here's a grep function that works based on this principle:

Function Select-ObjectPropertyValues {
    param(
    [Parameter(Mandatory=$true,Position=0)]
    [String]
    $Pattern,
    [Parameter(ValueFromPipeline)]
    $input)

    $input | Where-Object {($_.PSObject.Properties | Where-Object {$_.Value -match $Pattern} | Measure-Object).count -gt 0} | Write-Output
}

You can enter the following formula in the cell where you want to see the Overdue or Not due result:

=IF(ISBLANK(O10),"",IF(O10<TODAY(),"Overdue","Not due"))

This formula first tests if the source cell is blank. If it is, then the result cell will be filled with the empty string. If the source is not blank, then the formula tests if the date in the source cell is before the current day. If it is, then the value is set to Overdue, otherwise it is set to Not due.

All of the following examples use

var str = "Hello, playground"

startIndex and endIndex

• startIndex is the index of the first character
• endIndex is the index after the last character.

Example

// character
str[str.startIndex] // H
str[str.endIndex]   // error: after last character

// range
let range = str.startIndex..<str.endIndex
str[range]  // "Hello, playground"

With Swift 4's one-sided ranges, the range can be simplified to one of the following forms.

let range = str.startIndex...
let range = ..<str.endIndex

I will use the full form in the follow examples for the sake of clarity, but for the sake of readability, you will probably want to use the one-sided ranges in your code.

after

As in: index(after: String.Index)

• after refers to the index of the character directly after the given index.

Examples

// character
let index = str.index(after: str.startIndex)
str[index]  // "e"

// range
let range = str.index(after: str.startIndex)..<str.endIndex
str[range]  // "ello, playground"

before

As in: index(before: String.Index)

• before refers to the index of the character directly before the given index.

Examples

// character
let index = str.index(before: str.endIndex)
str[index]  // d

// range
let range = str.startIndex..<str.index(before: str.endIndex)
str[range]  // Hello, playgroun

offsetBy

As in: index(String.Index, offsetBy: String.IndexDistance)

• The offsetBy value can be positive or negative and starts from the given index. Although it is of the type String.IndexDistance, you can give it an Int.

Examples

// character
let index = str.index(str.startIndex, offsetBy: 7)
str[index]  // p

// range
let start = str.index(str.startIndex, offsetBy: 7)
let end = str.index(str.endIndex, offsetBy: -6)
let range = start..<end
str[range]  // play

limitedBy

As in: index(String.Index, offsetBy: String.IndexDistance, limitedBy: String.Index)

• The limitedBy is useful for making sure that the offset does not cause the index to go out of bounds. It is a bounding index. Since it is possible for the offset to exceed the limit, this method returns an Optional. It returns nil if the index is out of bounds.

Example

// character
if let index = str.index(str.startIndex, offsetBy: 7, limitedBy: str.endIndex) {
    str[index]  // p
}

If the offset had been 77 instead of 7, then the if statement would have been skipped.

Why is String.Index needed?

It would be much easier to use an Int index for Strings. The reason that you have to create a new String.Index for every String is that Characters in Swift are not all the same length under the hood. A single Swift Character might be composed of one, two, or even more Unicode code points. Thus each unique String must calculate the indexes of its Characters.

It is possibly to hide this complexity behind an Int index extension, but I am reluctant to do so. It is good to be reminded of what is actually happening.

Try this simpler one,

cp /home/ankur/folder/file{1,2} /home/ankur/dest

If you want to copy all the 10 files then run this command,

 cp ~/Desktop/{xyz,file{1,2},next,files,which,are,not,similer} foo-bar

There is some flickering problem in {{ }} like when you refresh the page then for a short spam of time expression is seen.So we should use ng-bind instead of expression for data depiction.

ffmpeg -i movie.mp4 -ss 00:00:03 -t 00:00:08 -async 1 -c copy cut.mp4 

Use -c copy for make in instantly. In that case ffmpeg will not re-encode video, just will cut to according size.

Methods in other answers throw OverflowException if the float value is outside the Int range. https://docs.microsoft.com/en-us/dotnet/api/system.convert.toint32?view=netframework-4.8#System_Convert_ToInt32_System_Single_

int result = 0;
try {
    result = Convert.ToInt32(value);
}
catch (OverflowException) {
    if (value > 0) result = int.MaxValue;
    else result = int.Minvalue;
}

When the session expires the data is no longer present, so something like

if (!isset($_SESSION['id'])) {
    header("Location: destination.php");
    exit;
}

will redirect whenever the session is no longer active.

You can set how long the session cookie is alive using session.cookie_lifetime

ini_set("session.cookie_lifetime","3600"); //an hour

EDIT: If you are timing sessions out due to security concern (instead of convenience,) use the accepted answer, as the comments below show, this is controlled by the client and thus not secure. I never thought of this as a security measure.

Set IIS to forward your mail to the remote server. The specifics vary greatly depending on the version of IIS. For IIS 7.5:

1. Open IIS Manager
2. Connect to your server if needed
3. Select the server node; you should see an SMTP option on the right in the ASP.NET section
4. Double-click the SMTP icon.
5. Select the "Deliver e-mail to SMTP server" option and enter your server name, credentials, etc.

I tried the solution priyanka.sarkar mentioned and the didn't quite get it working as the OP asked. Here's the solution I ended up with:

            FROM  @T T2 
            WHERE WHERE T1.id = T2.id
            FOR XML PATH('')), 2, 1000000)
    FROM @T T1
GROUP BY ID

Just to add to CKoenig's response. His answer will work as long as the class you're dealing with is a reference type (like a class). If the custom object were a struct, this is a value type, and the results of .FirstOrDefault will give you a local copy of that, which will mean it won't persist back to the collection, as this example shows:

struct MyStruct
{
    public int TheValue { get; set; }
}

Test code:

List<MyStruct> coll = new List<MyStruct> {
                                            new MyStruct {TheValue = 10},
                                            new MyStruct {TheValue = 1},
                                            new MyStruct {TheValue = 145},
                                            };
var found = coll.FirstOrDefault(c => c.TheValue == 1);
found.TheValue = 12;

foreach (var myStruct in coll)
{
    Console.WriteLine(myStruct.TheValue);
}
Console.ReadLine();

The output is 10,1,145

Change the struct to a class and the output is 10,12,145

Like you said since the xpath for the next button is the same on every page it won't work. It's working as coded in that it does wait for the element to be displayed but since it's already displayed then the implicit wait doesn't apply because it doesn't need to wait at all. Why don't you use the fact that the url changes since from your code it appears to change when the next button is clicked. I do C# but I guess in Java it would be something like:

WebDriver driver = new FirefoxDriver();
String startURL = //a starting url;
String currentURL = null;
WebDriverWait wait = new WebDriverWait(driver, 10);

foo(driver,startURL);

/* go to next page */
if(driver.findElement(By.xpath("//*[@id='someID']")).isDisplayed()){
    String previousURL = driver.getCurrentUrl();
    driver.findElement(By.xpath("//*[@id='someID']")).click();  
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

    ExpectedCondition e = new ExpectedCondition<Boolean>() {
          public Boolean apply(WebDriver d) {
            return (d.getCurrentUrl() != previousURL);
          }
        };

    wait.until(e);
    currentURL = driver.getCurrentUrl();
    System.out.println(currentURL);
} 

Manually creating a folder named 'npm' in the displayed path fixed the problem.

Use Closure Compiler instead.

FOR ANYONE RUNNING AN OS WITH SELINUX: The correct way of allowing httpd to write to the laravel storage folder is:

sudo semanage fcontext -a -t httpd_sys_rw_content_t '/path/to/www/storage(/.*)?'

Then to apply the changes immediately:

sudo restorecon -F -r '/path/to/www/storage'

SELinux can be a pain to deal with, but if it's present then I'd STRONGLY ADVISE you learn it rather than bypassing it entirely.

This might work for you:

printf "{new\nto\nlinux}" | paste -sd' '            
{new to linux}

or:

printf "{new\nto\nlinux}" | tr '\n' ' '            
{new to linux}

or:

printf "{new\nto\nlinux}" |sed -e ':a' -e '$!{' -e 'N' -e 'ba' -e '}' -e 's/\n/ /g'
{new to linux}

Here is a function that will load CSS files with a success or failure callback. The failure callback will be called just once, if one or more resources fail to load. I think this approach is better than some of the other solutions because inserting a element into the DOM with an HREF causes an additional browser request (albeit, the request will likely come from cache, depending on response headers).

function loadCssFiles(urls, successCallback, failureCallback) {

    $.when.apply($,
        $.map(urls, function(url) {
            return $.get(url, function(css) {
                $("<style>" + css + "</style>").appendTo("head");
            });
        })
    ).then(function() {
        if (typeof successCallback === 'function') successCallback();
    }).fail(function() {
        if (typeof failureCallback === 'function') failureCallback();
    });

}

Usage as so:

loadCssFiles(["https://test.com/style1.css", "https://test.com/style2.css",],
    function() {
    alert("All resources loaded");
}, function() {
    alert("One or more resources failed to load");
});

Here is another function that will load both CSS and javascript files:

function loadJavascriptAndCssFiles(urls, successCallback, failureCallback) {

    $.when.apply($,
        $.map(urls, function(url) {
            if(url.endsWith(".css")) {
                return $.get(url, function(css) {
                    $("<style>" + css + "</style>").appendTo("head");
                });
            } else {
                return $.getScript(url);
            }
        })
    ).then(function() {
        if (typeof successCallback === 'function') successCallback();
    }).fail(function() {
        if (typeof failureCallback === 'function') failureCallback();
    });

}

This should help if you need a publicly exposed website but you're on a dev pc. Also to answer (I can't comment yet): "How do I post to an internal only running development server with this? – stryba "

NGROK creates a secure public URL to a local webserver on your development machine (Permanent URLs available for a fee, temporary for free).
1) Run ngrok.exe to open command line (on desktop)
2) Type ngrok.exe http 80 to start a tunnel,
3) test by browsing to the displayed web address which will forward and display the local default 80 page on your dev pc

Then use some of the tools recommended above to POST to your ngrok site ('https://xxxxxx.ngrok.io') to test your local code.

https://ngrok.com/ ngrok

document.getElementById('myframe1').contentWindow.document.getElementById('x')

Fiddle

contentWindow is supported by all browsers including the older versions of IE.

Note that if the iframe's src is from another domain, you won't be able to access its content due to the Same Origin Policy.

Java supports closures just fine. It just doesn't support functions, so the syntax you're used to for closures is much more awkward and bulky: you have to wrap everything up in a class with a method. For example,

public Runnable foo(final int x) {
  return new Runnable() {
    public void run() {
      System.out.println(x);
    }
  };
}

Will return a Runnable object whose run() method "closes over" the x passed in, just like in any language that supports first-class functions and closures.

Using asp.net, I believe you can do it this way :

myTextBox.Attributes.Add("readonly","readonly")

Can you try doing something like (to get the last entry):

linkedHashMap.entrySet().toArray()[linkedHashMap.size() -1];

You should use the method:

Convert.IsDBNull()

Considering it's built-in to the Framework, I would expect this to be the most efficient.

I'd suggest something along the lines of:

int? myValue = (Convert.IsDBNull(row["column"]) ? null : (int?) Convert.ToInt32(row["column"]));

And yes, the compiler should cache it for you.

Don't know if you resolved this problem, but I have just resolved the same issue from the other side.

It appears Selenium and Firefox have difficulty talking to each other - I suspect Firefox 'evolve' changes over a number of releases, so backward and forward compatibility are not always guaranteed, and incompatibility always seems to generate the same error.

My problem started when I moved from FF 15 to FF 16. Running on Ubuntu, this happens auto magically along with other upgrades but I believe this was the critical change.

The problem was resolved by moving from Selenium 2.24.1 to Selenium 2.25.0

As the selenium change is just download the jar file and run it instead of the old one,it's worth trying this as a quick and easy troubleshooter - if it doesn't help, just switch back. In your case, I'm not sure which version of Selenium to try, but I think 2.24 should work with FF 10.

Another issue I have found in the past is that Firefox would not run as root on Ubuntu. This happens if Selenium is running as a service, or possibly if it is fired up from a bash script or cron job. This may explain why it runs for you but not for Jenkins.

I have modified the Coop's answer. Please check the example FIDDLE Here's my edits:

$(window).scroll(function(){
  if ($(window).scrollTop() >= 330) {
    $('.sticky-header').addClass('fixed');
   }
   else {
    $('.sticky-header').removeClass('fixed');
   }
});

Use sudo apt-get install --only-upgrade nodejs to upgrade node (and only upgrade node) using the package manager.

The package name is nodejs, see https://stackoverflow.com/a/18130296/4578017 for details.

You can also use nvm to install and update node.

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.32.1/install.sh | bash

Then restart the terminal, use nvm ls-remote to get latest version list of node, and use nvm install lts/* to install latest LTS version.

nvm is more recommended way to install or update node, even if you are not going to switch versions.

      )

it is always good to restrict the DOM search. so better to use a parent also, so that the entire DOM won't be traversed.

IT IS VERY FAST

<div id="radioBtnDiv">
  <input name="myButton" type="radio" class="radioClass" value="manual" checked="checked"/>
 <input name="myButton" type="radio" class="radioClass" value="auto" checked="checked"/>

 $("input[name='myButton']",$('#radioBtnDiv')).change(
    function(e)
    {
        // your stuffs go here
    });

You can double protect your file removal with NSFileManager.defaultManager().isDeletableFileAtPath(PathName) As of now you MUST use do{}catch{} as the old error methods no longer work. isDeletableFileAtPath() is not a "throws" (i.e. "public func removeItemAtPath(path: String) throws") so it does not need the do...catch

let killFile = NSFileManager.defaultManager()

            if (killFile.isDeletableFileAtPath(PathName)){


                do {
                  try killFile.removeItemAtPath(arrayDictionaryFilePath)
                }
                catch let error as NSError {
                    error.description
                }

Express.js is a framework used for Node and it is most commonly used as a web application for node js.

Here is a link to a video on how to quickly set up a node app with express https://www.youtube.com/watch?v=QEcuSSnqvck

you can use system.diagnostocs.process to call out to 'net use .... with userid and password' or to a command shell that takes those.

You can find an easy guide here

The step are 2: - Copy the icon in the correct folder/folders - Change the AndroidManifest.xml

How about simply:

select distinct c1, c2 from t

or

select c1, c2, count(*)
from t
group by c1, c2

Just as Daniel said "Git and TFVC are the two source control options in TFS". Fortunately both are supported for now in VS Code.

You need to install the Azure Repos Extension for Visual Studio Code. The process of installing is pretty straight forward.

1. Search for Azure Repos in VS Code and select to install the one by Microsoft
2. Open File -> Preferences -> Settings

3. Add the following lines to your user settings

   If you have VS 2015 installed on your machine, your path to Team Foundation tool (tf.exe) may look like this:

   {
       "tfvc.location": "C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\Common7\\IDE\\tf.exe",
       "tfvc.restrictWorkspace": true
   }

   Or for VS 2017:

   {
       "tfvc.location": "C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Enterprise\\Common7\\IDE\\CommonExtensions\\Microsoft\\TeamFoundation\\Team Explorer\\tf.exe",
       "tfvc.restrictWorkspace": true
   }

4. Open a local folder (repository), From View -> Command Pallette ..., type team signin

5. Provide user name --> Enter --> Provide password to connect to TFS.

Please refer to below links for more details:

• Using Visual Studio Code & Team Foundation Version Control (TFVC)
• Team Foundation Version Control (TFVC) Support
• Using Version Control in VS Code

Note that Server Workspaces are not supported:

"TFVC support is limited to Local workspaces":

For Swift 2.3

extension UIButton {
    func underline() {
        let attributedString = NSMutableAttributedString(string: (self.titleLabel?.text!)!)
        attributedString.addAttribute(NSUnderlineStyleAttributeName, value: NSUnderlineStyle.StyleSingle.rawValue, range: NSRange(location: 0, length: (self.titleLabel?.text!.characters.count)!))
        self.setAttributedTitle(attributedString, forState: .Normal)
    }
}

and in ViewController

@IBOutlet var yourButton: UIButton!

in ViewDidLoad Method or in your function just write

yourButton.underline()

it will underline the title of your button

You can set using SelectedIndex

comboBox1.SelectedIndex= 1;

OR

SelectedItem

comboBox1.SelectedItem = "your value"; // 

The latter won't throw an exception if the value is not available in the combobox

EDIT

If the value to be selected is not specific then you would be better off with this

comboBox1.SelectedIndex = comboBox1.Items.Count - 1;

(Assuming you are not required to input the string from directly within Python code)

to get around the Issue Andrew Dalke pointed out, simply type the literal string into a text file and then use this;

input_ = '/directory_of_text_file/your_text_file.txt' 
input_open   = open(input_,'r+')
input_string = input_open.read()

print input_string

This will print the literal text of whatever is in the text file, even if it is;

 '   ''' """  “ \

Not fun or optimal, but can be useful, especially if you have 3 pages of code that would’ve needed character escaping.

You neglected to say which version of C you are concerned about. Let's assume it's this one:

http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1570.pdf

As you can see by reading the specification, the standard definitions of true and false are 1 and 0, yes.

If your question is about a different version of C, or about non-standard definitions for true and false, then ask a more specific question.

if we are talking about validations also why we have not checked for null string entries. Any specific reasons?

I think below way help since IsNullOrEmpty is a system defined method and ternary operators have cyclomatic complexity = 1 while if() {} else {} has value 2.

    public static string Truncate(string input, int truncLength)
    {
        return (!String.IsNullOrEmpty(input) && input.Length >= truncLength)
                   ? input.Substring(0, truncLength)
                   : input;
    }

A 32-bit float has about 7 digits of precision and a 64-bit double has about 16 digits of precision

Long answer:

Floating-point numbers have three components:

1. A sign bit, to determine if the number is positive or negative.
2. An exponent, to determine the magnitude of the number.
3. A fraction, which determines how far between two exponent values the number is. This is sometimes called “the significand, mantissa, or coefficient”

Essentially, this works out to sign * 2^exponent * (1 + fraction). The “size” of the number, it’s exponent, is irrelevant to us, because it only scales the value of the fraction portion. Knowing that log10(n) gives the number of digits of n,† we can determine the precision of a floating point number with log10(largest_possible_fraction). Because each bit in a float stores 2 possibilities, a binary number of n bits can store a number up to 2n - 1 (a total of 2n values where one of the values is zero). This gets a bit hairier, because it turns out that floating point numbers are stored with one less bit of fraction than they can use, because zeroes are represented specially and all non-zero numbers have at least one non-zero binary bit.‡

Combining this, the digits of precision for a floating point number is log10(2n), where n is the number of bits of the floating point number’s fraction. A 32-bit float has 24 bits of fraction for ˜7.22 decimal digits of precision, and a 64-bit double has 53 bits of fraction for ˜15.95 decimal digits of precision.

For more on floating point accuracy, you might want to read about the concept of a machine epsilon.

† For n = 1 at least — for other numbers your formula will look more like ?log10(|n|)? + 1.

‡ “This rule is variously called the leading bit convention, the implicit bit convention, or the hidden bit convention.” (Wikipedia)

I had the same problem - I was fetching a page from my own site, which was served over HTTPS, but curl was giving the same "SSL certificate problem" message. I worked around it by adding a -k flag to the call to allow insecure connections.

curl -k https://whatever.com/script.php

Edit: I discovered the root of the problem. I was using an SSL certificate (from StartSSL, but I don't think that matters much) and hadn't set up the intermediate certificate properly. If you're having the same problem as user1270392 above, it's probably a good idea to test your SSL cert and fix any issues with it before resorting to the curl -k fix.

recursion + memorization could lead to a more efficient solution compare with a pure iterative approach, e.g. check this: http://jsperf.com/fibonacci-memoized-vs-iterative-for-large-n

JSON is perfectly capable of expressing lists of integers, and the JSON you have posted is valid. You can simply separate the integers by commas:

{
    "Id": "610",
    "Name": "15",
    "Description": "1.99",
    "ItemModList": [42, 47, 139]
}

The best way doing this - especially if you're adding more than one condition - is:

$values = array(...); // array of your values
$qb->andWhere('where', $qb->expr()->in('r.winner', $values));

If your array of values contains strings, you can't use the setParameter method with an imploded string, because your quotes will be escaped!

To permanently attach a database file (.mdf) from the Data Connections node

1. Open the shortcut menu for Data Connections and choose Add New Connection.

   The Add Connection dialog box appears.

2. Choose the Change button.

   The Change Data Source dialog box appears.

3. Select Microsoft SQL Server and choose the OK button.

   The Add Connection dialog box reappears, with Microsoft SQL Server (SqlClient) displayed in the Data source text box.

4. In the Server Name box, type or browse to the path to the local instance of SQL Server. You can type the following:

   • "." for the default instance on your computer.
   • "(LocalDB)\v11.0" for the default instance of SQL Server Express LocalDB.
   • ".\SQLEXPRESS" for the default instance of SQL Server Express.

   For information about SQL Server Express LocalDB and SQL Server Express, see Local Data Overview.

5. Select either Use Windows Authentication or Use SQL Server Authentication.

6. Choose Attach a database file, Browse, and open an existing .mdf file.

7. Choose the OK button.

   The new database appears in Server Explorer. It will remain connected to SQL Server until you explicitly detach it.

let url = URL(string: "URLSTRING HERE")
let anyvar =  String(describing: url)

A person might get this while working with factory functions, so I can confirm this is valid syntax:

$user = factory(User::class, 1)->create()->first();

You might see the collection instance error if you do something like:

$user = factory(User::class, 1)->create()->id;

so change it to:

$user = factory(User::class, 1)->create()->first()->id;

I let Eclipse do it for me when they are being used in an anonymous class, which is increasing due to my use of Google Collection API.

public class MainActivity extends AppCompatActivity implements View.OnClickListener

Whenever you use (this) on click events, your main activity has to implement ocClickListener. Android Studio does it for you, press alt+enter on the 'this' word.

You want rows where that condition is true so you need a comma:

data[data$Ozone > 14, ]

In case anybody stumbles upon this question who cannot reload their webserver (long running console command like a queue runner) or needs to reload their .env file mid-request, i found a way to properly reload .env variables in laravel 5.

I found a solution by extending ArrayAdapter and Overriding the getView method.

import android.content.Context;
import android.support.annotation.NonNull;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.TextView;

/**
 * A SpinnerAdapter which does not show the value of the initial selection initially,
 * but an initialText.
 * To use the spinner with initial selection instead call notifyDataSetChanged().
 */
public class SpinnerAdapterWithInitialText<T> extends ArrayAdapter<T> {

    private Context context;
    private int resource;

    private boolean initialTextWasShown = false;
    private String initialText = "Please select";

    /**
     * Constructor
     *
     * @param context The current context.
     * @param resource The resource ID for a layout file containing a TextView to use when
     *                 instantiating views.
     * @param objects The objects to represent in the ListView.
     */
    public SpinnerAdapterWithInitialText(@NonNull Context context, int resource, @NonNull T[] objects) {
        super(context, resource, objects);
        this.context = context;
        this.resource = resource;
    }

    /**
     * Returns whether the user has selected a spinner item, or if still the initial text is shown.
     * @param spinner The spinner the SpinnerAdapterWithInitialText is assigned to.
     * @return true if the user has selected a spinner item, false if not.
     */
    public boolean selectionMade(Spinner spinner) {
        return !((TextView)spinner.getSelectedView()).getText().toString().equals(initialText);
    }

    /**
     * Returns a TextView with the initialText the first time getView is called.
     * So the Spinner has an initialText which does not represent the selected item.
     * To use the spinner with initial selection instead call notifyDataSetChanged(),
     * after assigning the SpinnerAdapterWithInitialText.
     */
    @Override
    public View getView(int position, View recycle, ViewGroup container) {
        if(initialTextWasShown) {
            return super.getView(position, recycle, container);
        } else {
            initialTextWasShown = true;
            LayoutInflater inflater = LayoutInflater.from(context);
            final View view = inflater.inflate(resource, container, false);

            ((TextView) view).setText(initialText);

            return view;
        }
    }
}

What Android does when initialising the Spinner, is calling getView for the selected item before calling getView for all items in T[] objects. The SpinnerAdapterWithInitialText returns a TextView with the initialText, the first time it is called. All the other times it calls super.getView which is the getView method of ArrayAdapter which is called if you are using the Spinner normally.

To find out whether the user has selected a spinner item, or if the spinner still displays the initialText, call selectionMade and hand over the spinner the adapter is assigned to.

The portable way to do this (ensuring that you get 0x00 0x00 0x00 0xaf everywhere) is to use shifts:

unsigned char bytes[4];
unsigned long n = 175;

bytes[0] = (n >> 24) & 0xFF;
bytes[1] = (n >> 16) & 0xFF;
bytes[2] = (n >> 8) & 0xFF;
bytes[3] = n & 0xFF;

The methods using unions and memcpy() will get a different result on different machines.

The issue you are having is with the printing rather than the conversion. I presume you are using char rather than unsigned char, and you are using a line like this to print it:

printf("%x %x %x %x\n", bytes[0], bytes[1], bytes[2], bytes[3]);

When any types narrower than int are passed to printf, they are promoted to int (or unsigned int, if int cannot hold all the values of the original type). If char is signed on your platform, then 0xff likely does not fit into the range of that type, and it is being set to -1 instead (which has the representation 0xff on a 2s-complement machine).

-1 is promoted to an int, and has the representation 0xffffffff as an int on your machine, and that is what you see.

Your solution is to either actually use unsigned char, or else cast to unsigned char in the printf statement:

printf("%x %x %x %x\n", (unsigned char)bytes[0],
                        (unsigned char)bytes[1],
                        (unsigned char)bytes[2],
                        (unsigned char)bytes[3]);

I agree with @arcy, the problem is on client side, on my case it was because of nginx, let me elaborate I am using nginx as the frontend (so I can distribute load, ssl, etc ...) and using proxy_pass http://127.0.0.1:8080 to forward the appropiate requests to tomcat.

There is a default value for the nginx variable proxy_read_timeout of 60s that should be enough, but on some peak moments my setup would error with the java.io.IOException: Broken pipe changing the value will help until the root cause (60s should be enough) can be fixed.

NOTE: I made a new answer so I could expand a bit more with my case (it was the only mention I found about this error on internet after looking quite a lot)

Directory.GetAccessControl(path) does what you are asking for.

public static bool HasWritePermissionOnDir(string path)
{
    var writeAllow = false;
    var writeDeny = false;
    var accessControlList = Directory.GetAccessControl(path);
    if (accessControlList == null)
        return false;
    var accessRules = accessControlList.GetAccessRules(true, true, 
                                typeof(System.Security.Principal.SecurityIdentifier));
    if (accessRules ==null)
        return false;

    foreach (FileSystemAccessRule rule in accessRules)
    {
        if ((FileSystemRights.Write & rule.FileSystemRights) != FileSystemRights.Write) 
            continue;

        if (rule.AccessControlType == AccessControlType.Allow)
            writeAllow = true;
        else if (rule.AccessControlType == AccessControlType.Deny)
            writeDeny = true;
    }

    return writeAllow && !writeDeny;
}

(FileSystemRights.Write & rights) == FileSystemRights.Write is using something called "Flags" btw which if you don't know what it is you should really read up on :)

I was also searching for a simple solution, and this is what I came up with, based on all other answers and my research. Basically, class Person has another constructor, called 'class' which works with a generic object of the same 'format' as Person. I hope this might help somebody as well.

For Macs with Homebrew. I had this problem when fetching the db from Heroku. I've fixed it just running:

brew upgrade postgresql

Curtis's answer was very close to what I needed, but I changed it up a little.

Where he used:

$options['inputs']['name'][] = $new_input['name'];

I used:

$options[]['inputs']['name'] = $new_input['name'];

Here's my actual code using a query from a DB:

while($row=mysql_fetch_array($result)){ 
    $dtlg_array[]['dt'] = $row['dt'];
    $dtlg_array[]['lat'] = $row['lat'];
    $dtlg_array[]['lng'] = $row['lng'];
}

Thanks!

The answer depends on specifically what you mean by the "top 1000 distinct" records.

If you mean that you want to return at most 1000 distinct records, regardless of how many duplicates are in the table, then write this:

SELECT DISTINCT TOP 1000 id, uname, tel
FROM Users
ORDER BY <sort_columns>

If you only want to search the first 1000 rows in the table, and potentially return much fewer than 1000 distinct rows, then you would write it with a subquery or CTE, like this:

SELECT DISTINCT *
FROM
(
    SELECT TOP 1000 id, uname, tel
    FROM Users
    ORDER BY <sort_columns>
) u

The ORDER BY is of course optional if you don't care about which records you return.

myArray.sample(x) can also help you to get x random elements from the array.

To set a default value to a column, try this:

ALTER TABLE tb_TableName
ALTER COLUMN Record_Status SET DEFAULT 'default value'

Using HTML5 mode requires URL rewriting on server side, basically you have to rewrite all your links to entry point of your application (e.g. index.html). Requiring a <base> tag is also important for this case, as it allows AngularJS to differentiate between the part of the url that is the application base and the path that should be handled by the application. For more information, see AngularJS Developer Guide - Using $location HTML5 mode Server Side.

How to: Configure your server to work with html5Mode¹

When you have html5Mode enabled, the # character will no longer be used in your urls. The # symbol is useful because it requires no server side configuration. Without #, the url looks much nicer, but it also requires server side rewrites. Here are some examples:

To solve this problem open nutget package manager console and select your project and type install-package microsoft.report.viewer and wait to install

any():

if any(t < 0 for t in x):

Also, if you're going to use "True in ...", make it a generator expression so it doesn't take O(n) memory:

if True in (t < 0 for t in x):

to clarify your question:

From Python Source code to Java source code? (I don't think so)

.. or from Python source code to Java Bytecode? (Jython does this under the hood)

Your sample does not work in IE for me, you have to specify Doctype header in your document to render your page in standard way in IE to use the content CSS property:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<head>
<link href="style.css" rel="stylesheet" type="text/css">
</head>
<html>

<ul>
    <li>One</li>
    <li>Two</li>
    <li>Three</li>
    <li>Four</li>
    <li>Five</li>
</ul>

</html>

Second way is to use CSS 3 selectors

li:not(:last-of-type):after
{
    content:           " |";
}

But you still need to specify Doctype

And third way is to use JQuery with some script like following:

<script type="text/javascript" src="jquery-1.4.1.js"></script>
<link href="style2.css" rel="stylesheet" type="text/css">
</head>
<html>

<ul>
    <li>One</li>
    <li>Two</li>
    <li>Three</li>
    <li>Four</li>
    <li>Five</li>
</ul>

<script type="text/javascript">
  $(document).ready(function () {
      $("li:not(:last)").append(" | ");
    });
</script>

Advantage of third way is that you dont have to specify doctype and jQuery will take care of compatibility.

And for SBT : excludeDependencies += "log4j" % "log4j"

Also, name it divrat.m, not divrat.M. This shouldn't matter on most OSes, but who knows...

You can also test whether matlab can find a function by using the which command, i.e.

which divrat

Try this instead to only select the visible elements under the tbody:

$('tbody :visible').highlight(myArray[i]);

add Location to your constructor from @angular/common

constructor(private _location: Location) {}

add the back function:

back() {
  this._location.back();
}

and then in your view:

<button class="btn" (click)="back()">Back</button>

You don't need to instantiate an object, because yau are going to use a static variable: Console.WriteLine(Book.myInt);

The name open addressing refers to the fact that the location ("address") of the element is not determined by its hash value. (This method is also called closed hashing).

In separate chaining, each bucket is independent, and has some sort of ADT (list, binary search trees, etc) of entries with the same index. In a good hash table, each bucket has zero or one entries, because we need operations of order O(1) for insert, search, etc.

This is a example of separate chaining using C++ with a simple hash function using mod operator (clearly, a bad hash function)

Is it possible to add onclick to a div and have it occur if any area of the div is clicked.

Yes … although it should be done with caution. Make sure there is some mechanism that allows keyboard access. Build on things that work

If yes then why is the onclick method not going through to my div.

You are assigning a string where a function is expected.

divTag.onclick = printWorking;

There are nicer ways to assign event handlers though, although older versions of Internet Explorer are sufficiently different that you should use a library to abstract it. There are plenty of very small event libraries and every major library jQuery) has event handling functionality.

That said, now it is 2019, older versions of Internet Explorer no longer exist in practice so you can go direct to addEventListener

The modern way is to use the CSS flexbox, see support tables.

.container {_x000D_
  display: flex;_x000D_
}_x000D_
.container > div {_x000D_
  flex: 1; /*grow*/_x000D_
}

<div class="container">_x000D_
  <div>Left div</div>_x000D_
  <div>Middle div</div>  _x000D_
  <div>Right div</div>_x000D_
</div>

You can also use CSS grid, see support tables.

.container {_x000D_
  display: grid;_x000D_
  grid-template-columns: 1fr 1fr 1fr; /* fraction*/_x000D_
}

<div class="container">_x000D_
  <div>Left div</div>_x000D_
  <div>Middle div</div>  _x000D_
  <div>Right div</div>_x000D_
</div>

Use not, for example:

return not myval

Ensure that you have following JARS in place: 1) jackson-core-asl-1.9.13 2) jackson-jaxrs-1.9.13 3) jackson-mapper-asl-1.9.13 4) jackson-xc-1.9.13

Those GCD functions provided by Commons-Math and Guava have some differences.

• Commons-Math throws an ArithematicException.class only for Integer.MIN_VALUE or Long.MIN_VALUE.
  • Otherwise, handles the value as an absolute value.
• Guava throws an IllegalArgumentException.class for any negative values.

It's not working because the entire for loop (from the for to the final closing parenthesis, including the commands between those) is being evaluated when it's encountered, before it begins executing.

In other words, %count% is replaced with its value 1 before running the loop.

What you need is something like:

setlocal enableextensions enabledelayedexpansion
set /a count = 1
for /f "tokens=*" %%a in (config.properties) do (
  set /a count += 1
  echo !count!
)
endlocal

Delayed expansion using ! instead of % will give you the expected behaviour. See also here.

Also keep in mind that setlocal/endlocal actually limit scope of things changed inside so that they don't leak out. If you want to use count after the endlocal, you have to use a "trick" made possible by the very problem you're having:

endlocal && set count=%count%

Let's say count has become 7 within the inner scope. Because the entire command is interpreted before execution, it effectively becomes:

endlocal && set count=7

Then, when it's executed, the inner scope is closed off, returning count to it's original value. But, since the setting of count to seven happens in the outer scope, it's effectively leaking the information you need.

You can string together multiple sub-commands to leak as much information as you need:

endlocal && set count=%count% && set something_else=%something_else%

• All as varchar (they aren't numbers but "collections of digits")
• Country + area + number separately

@jk1 answer is perfect, since @igor Ganapolsky asked, why can't we use Mockito.mock here? i post this answer.

For that we have provide one setter method for myobj and set the myobj value with mocked object.

class MyClass {
    MyInterface myObj;

    public void abc() {
        myObj.myMethodToBeVerified (new String("a"), new String("b"));
    }

    public void setMyObj(MyInterface obj)
    {
        this.myObj=obj;
    }
}

In our Test class, we have to write below code

class MyClassTest {

MyClass myClass = new MyClass();

    @Mock
    MyInterface myInterface;

    @test
    testAbc() {
        myclass.setMyObj(myInterface); //it is good to have in @before method
        myClass.abc();
        verify(myInterface).myMethodToBeVerified(new String("a"), new String("b"));
     }
}

$("#dropdownList option[text='it\'s me']").attr("selected","selected"); 

Assuming upperDate is always later than lowerDate and both are datetime.date objects:

if lowerDate.year == upperDate.year:
    monthsInBetween = range( lowerDate.month + 1, upperDate.month )
elif upperDate.year > lowerDate.year:
    monthsInBetween = range( lowerDate.month + 1, 12 )
    for year in range( lowerDate.year + 1, upperDate.year ):
        monthsInBetween.extend( range(1,13) )
    monthsInBetween.extend( range( 1, upperDate.month ) )

I haven't tested this thoroughly, but it looks like it should do the trick.

This line works only for the DataGridView Control on Windows Forms:

DataObject dataObj = dataGridView1.GetClipboardContent();

This one addresses the same issue, but for the DataGrid control for the WPF Framework:

    private void copyDataGridContentToClipboard()
    {
        datagridGrupeProductie.SelectAll();
        datagridGrupeProductie.ClipboardCopyMode = DataGridClipboardCopyMode.IncludeHeader;

        ApplicationCommands.Copy.Execute(null, datagridGrupeProductie);
        datagridGrupeProductie.UnselectAll();
    }


    private void rightClickGrupeProductie_Click(object sender, RoutedEventArgs e)
    {
        copyDataGridContentToClipboard();
        Microsoft.Office.Interop.Excel.Application excelApp;

        object misValue = System.Reflection.Missing.Value;
        excelApp = new Microsoft.Office.Interop.Excel.Application();
        excelApp.Visible = true;
        excelWkbk = excelApp.Workbooks.Add(misValue);
        excelWksht = (Microsoft.Office.Interop.Excel.Worksheet)excelWkbk.Worksheets.get_Item(1);
        Microsoft.Office.Interop.Excel.Range CR = (Microsoft.Office.Interop.Excel.Range)excelWksht.Cells[1, 1];
        CR.Select();
        excelWksht.PasteSpecial(CR, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, true);
    }

/var/www/html is just the default root folder of the web server. You can change that to be whatever folder you want by editing your apache.conf file (usually located in /etc/apache/conf) and changing the DocumentRoot attribute (see http://httpd.apache.org/docs/current/mod/core.html#documentroot for info on that)

Many hosts don't let you change these things yourself, so your mileage may vary. Some let you change them, but only with the built in admin tools (cPanel, for example) instead of via a command line or editing the raw config files.

This should work:

DECLARE db_cursor CURSOR FOR SELECT name, age, color FROM table; 
DECLARE @myName VARCHAR(256);
DECLARE @myAge INT;
DECLARE @myFavoriteColor VARCHAR(40);
OPEN db_cursor;
FETCH NEXT FROM db_cursor INTO @myName, @myAge, @myFavoriteColor;
WHILE @@FETCH_STATUS = 0  
BEGIN  

       --Do stuff with scalar values

       FETCH NEXT FROM db_cursor INTO @myName, @myAge, @myFavoriteColor;
END;
CLOSE db_cursor;
DEALLOCATE db_cursor;

I Have Been suffering from same thing since long time. It specially happens when you're connected to remote server(Which might be slow), or you have poor network connection. I doubt if Microsoft knows what the right answer is.

But since I've tried to find the solution. Only 1 layman approach worked

• Click the close button over the tab of query which you are being suffered of. After a while (If Microsoft is not harsh on you !!!) you might get a window asking this

"The query is currently executing. Do you want to cancel the query?"

• Click on "Yes"

• After a while it will ask to whether you want to save this query or not?

• Click on "Cancel"

And post that, may be you're studio is stable again to execute your query.

What it does in background is disconnecting your query window with the connection. So for running the query again, it will take time for connecting the remote server again. But trust me this trade-off is far better than the suffering of seeing that timer which runs for eternity.

PS: This works for me, Kudos if works for you too. !!!

Just make a comparison function/functor:

bool my_cmp(const data& a, const data& b)
{
    // smallest comes first
    return a.word.size() < b.word.size();
}

std::sort(info.begin(), info.end(), my_cmp);

Or provide an bool operator<(const data& a) const in your data class:

struct data {
    string word;
    int number;

    bool operator<(const data& a) const
    {
        return word.size() < a.word.size();
    }
};

or non-member as Fred said:

struct data {
    string word;
    int number;
};

bool operator<(const data& a, const data& b)
{
    return a.word.size() < b.word.size();
}

and just call std::sort():

std::sort(info.begin(), info.end());

Open with append:

pFile2 = fopen("myfile2.txt", "a");

then just write to pFile2, no need to fseek().

If you really want to use Deleted, you'd have to make your foreign keys nullable, but then you'd end up with orphaned records (which is one of the main reasons you shouldn't be doing that in the first place). So just use Remove()

ObjectContext.DeleteObject(entity) marks the entity as Deleted in the context. (It's EntityState is Deleted after that.) If you call SaveChanges afterwards EF sends a SQL DELETE statement to the database. If no referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

EntityCollection.Remove(childEntity) marks the relationship between parent and childEntity as Deleted. If the childEntity itself is deleted from the database and what exactly happens when you call SaveChanges depends on the kind of relationship between the two:

A thing worth noting is that setting .State = EntityState.Deleted does not trigger automatically detected change. (archive)

Try this:

li.setBackgroundColor(android.R.color.red); //or which ever color do you want

EDIT: Posting logcat file would also help.

If you need a one-liner (i.e. for Jasper Reports formula) and don't mind if the adjustment is not exactly one month (i.e "30 days" is enough):

new Date($F{invoicedate}.getTime() + 30L * 24L * 60L * 60L * 1000L)

SELECT @variable1 = col1, @variable2 = col2
FROM table1

Also, you can use an IDE like CLion (JetBrains) or a text editor like Atom, with the gpp-compiler plugin, works like a charm (F5 to compile & execute).

Look at the traceback:

Traceback (most recent call last):
  File "C:\Python33\lib\site-packages\bottle.py", line 821, in _cast
    out = iter(out)
TypeError: 'bool' object is not iterable

Your code isn't iterating the value, but the code receiving it is.

The solution is: return an iterable. I suggest that you either convert the bool to a string (str(False)) or enclose it in a tuple ((False,)).

Always read the traceback: it's correct, and it's helpful.

<script type = "text/javascript">
function get_values(input_id)
{
var input = document.getElementById(input_id).value;
document.write(input);
}
</script>

<!--Insert more code here-->


<input type = "text" id = "textfield">
<input type = "button" onclick = "get('textfield')" value = "submit">

Next time you ask a question here, include more detail and what you have tried.

There are at least 5 ways to do this:

If you want to convert to integers only, another fast (and short) way is the double-bitwise not (i.e. using two tilde characters):

e.g.

~~x;

Reference: http://james.padolsey.com/cool-stuff/double-bitwise-not/

The 5 common ways I know so far to convert a string to a number all have their differences (there are more bitwise operators that work, but they all give the same result as ~~). This JSFiddle shows the different results you can expect in the debug console: http://jsfiddle.net/TrueBlueAussie/j7x0q0e3/22/

var values = ["123",
          undefined,
          "not a number",
          "123.45",
          "1234 error",
          "2147483648",
          "4999999999"
          ];

for (var i = 0; i < values.length; i++){
    var x = values[i];

    console.log(x);
    console.log(" Number(x) = " + Number(x));
    console.log(" parseInt(x, 10) = " + parseInt(x, 10));
    console.log(" parseFloat(x) = " + parseFloat(x));
    console.log(" +x = " + +x);
    console.log(" ~~x = " + ~~x);
}

Debug console:

123
  Number(x) = 123
  parseInt(x, 10) = 123
  parseFloat(x) = 123
  +x = 123
  ~~x = 123
undefined
  Number(x) = NaN
  parseInt(x, 10) = NaN
  parseFloat(x) = NaN
  +x = NaN
  ~~x = 0
null
  Number(x) = 0
  parseInt(x, 10) = NaN
  parseFloat(x) = NaN
  +x = 0
  ~~x = 0
"not a number"
  Number(x) = NaN
  parseInt(x, 10) = NaN
  parseFloat(x) = NaN
  +x = NaN
  ~~x = 0
123.45
  Number(x) = 123.45
  parseInt(x, 10) = 123
  parseFloat(x) = 123.45
  +x = 123.45
  ~~x = 123
1234 error
  Number(x) = NaN
  parseInt(x, 10) = 1234
  parseFloat(x) = 1234
  +x = NaN
  ~~x = 0
2147483648
  Number(x) = 2147483648
  parseInt(x, 10) = 2147483648
  parseFloat(x) = 2147483648
  +x = 2147483648
  ~~x = -2147483648
4999999999
  Number(x) = 4999999999
  parseInt(x, 10) = 4999999999
  parseFloat(x) = 4999999999
  +x = 4999999999
  ~~x = 705032703

The ~~x version results in a number in "more" cases, where others often result in undefined, but it fails for invalid input (e.g. it will return 0 if the string contains non-number characters after a valid number).

Overflow

Please note: Integer overflow and/or bit truncation can occur with ~~, but not the other conversions. While it is unusual to be entering such large values, you need to be aware of this. Example updated to include much larger values.

Some Perf tests indicate that the standard parseInt and parseFloat functions are actually the fastest options, presumably highly optimised by browsers, but it all depends on your requirement as all options are fast enough: http://jsperf.com/best-of-string-to-number-conversion/37

This all depends on how the perf tests are configured as some show parseInt/parseFloat to be much slower.

My theory is:

• Lies
• Darn lines
• Statistics
• JSPerf results :)

Angular deprecated $cookieStore in version 1.4.x, so use $cookies instead if you are using latest version of angular. Syntax remain same for $cookieStore & $cookies:

$cookies.put("key", "value"); 
var value = $cookies.get("key");

See the Docs for an API overview. Mind also that the cookie service has been enhanced with some new important features like setting expiration (see this answer) and domain (see CookiesProvider Docs).

Note that, in version 1.3.x or below, $cookies has a different syntax than above:

$cookies.key = "value";
var value = $cookies.value; 

Also if you are using bower, make sure to type your package name correctly:

bower install [email protected] 

where X.Y.Z is the AngularJS version you are running. There's another package in bower "angular-cookie"(without the 's') which is not the official angular package.

Use AssemblyInfo.cs

Create the file in App_Code: and fill out the following or use Google for other attribute/property possibilities.

AssemblyInfo.cs

using System.Reflection;

[assembly: AssemblyDescription("Very useful stuff here.")]
[assembly: AssemblyCompany("companyname")]
[assembly: AssemblyCopyright("Copyright © me 2009")]
[assembly: AssemblyProduct("NeatProduct")]
[assembly: AssemblyVersion("1.1.*")]

AssemblyVersion being the part you are really after.

Then if you are working on a website, in any aspx page, or control, you can add in the <Page> tag, the following:

CompilerOptions="<folderpath>\App_Code\AssemblyInfo.cs"

(replacing folderpath with appropriate variable of course).

I don't believe you need to add compiler options in any manner for other classes; all the ones in the App_Code should receive the version information when they are compiled.

Hope that helps.

This really works, I spent a lot of time trying multiple variants.

If you happen to use CRA with default yarn package manager use the following. Worked for me.

yarn add [email protected]

In addition to Will Dean's version, the following are common for whole buffer initialization:

or

char s[10];
memset(s, '\0', sizeof(s));

or

char s[10];
strncpy(s, "", sizeof(s));

SQL is a standard and there are many database vendors like Microsoft,Oracle who implements this standard using their own proprietary language.

Microsoft uses T-SQL to implement SQL standard to interact with data whereas oracle uses PL/SQL.

See also see https://angular.io/guide/router#the-default-route-to-heroes

RouterConfig = [
  { path: '', redirectTo: '/heroes', pathMatch: 'full' },
  { path: 'heroes', component: HeroComponent,
    children: [
      { path: '', redirectTo: '/detail', pathMatch: 'full' },
      { path: 'detail', component: HeroDetailComponent }

  }
];

There is also the catch-all route

{ path: '**', redirectTo: '/heroes', pathMatch: 'full' },

which redirects "invalid" urls.

V3-alpha (vladivostok)

Use path / and redirectTo

RouterConfig = [
  { path: '/', redirectTo: 'heroes', terminal: true },
  { path: 'heroes', component: HeroComponent,
    children: [
      { path: '/', redirectTo: 'detail', terminal: true },
      { path: 'detail', component: HeroDetailComponent }
    ] 
  }
];

RC.1 @angular/router

The RC router doesn't yet support useAsDefault. As a workaround you can navigate explicitely.

In the root component

export class AppComponent {
  constructor(router:Router) {
    router.navigate(['/Merge']);
  }
}

for other components

export class OtherComponent {
  constructor(private router:Router) {}

  routerOnActivate(curr: RouteSegment, prev?: RouteSegment, currTree?: RouteTree, prevTree?: RouteTree) : void {
    this.router.navigate(['SomeRoute'], curr);
  }
}

I guess I'm a bit late on this question but I'll write something anyway for anyone having the same problem. This is the same answer as I gave to this question.

My problem was that I'd like my application to be a GUI application but the processes executed should be run in the background without any interactive console window attached. I think this solution should also work when the parent process is a console process. You may have to remove the "CREATE_NO_WINDOW" flag though.

I managed to solve this using GenerateConsoleCtrlEvent() with a wrapper app. The tricky part is just that the documentation is not really clear on exactly how it can be used and the pitfalls with it.

My solution is based on what is described here. But that didn't really explain all the details either and with an error, so here is the details on how to get it working.

Create a new helper application "Helper.exe". This application will sit between your application (parent) and the child process you want to be able to close. It will also create the actual child process. You must have this "middle man" process or GenerateConsoleCtrlEvent() will fail.

Use some kind of IPC mechanism to communicate from the parent to the helper process that the helper should close the child process. When the helper get this event it calls "GenerateConsoleCtrlEvent(CTRL_BREAK, 0)" which closes down itself and the child process. I used an event object for this myself which the parent completes when it wants to cancel the child process.

To create your Helper.exe create it with CREATE_NO_WINDOW and CREATE_NEW_PROCESS_GROUP. And when creating the child process create it with no flags (0) meaning it will derive the console from its parent. Failing to do this will cause it to ignore the event.

It is very important that each step is done like this. I've been trying all different kinds of combinations but this combination is the only one that works. You can't send a CTRL_C event. It will return success but will be ignored by the process. CTRL_BREAK is the only one that works. Doesn't really matter since they will both call ExitProcess() in the end.

You also can't call GenerateConsoleCtrlEvent() with a process groupd id of the child process id directly allowing the helper process to continue living. This will fail as well.

I spent a whole day trying to get this working. This solution works for me but if anyone has anything else to add please do. I went all over the net finding lots of people with similar problems but no definite solution to the problem. How GenerateConsoleCtrlEvent() works is also a bit weird so if anyone knows more details on it please share.

Array's include?method accepts any object, not just a string. This should work:

@suggested_horses = [] 
@suggested_horses << Horse.first(:offset => rand(Horse.count)) 
while @suggested_horses.length < 8 
  horse = Horse.first(:offset => rand(Horse.count)) 
  @suggested_horses << horse unless @suggested_horses.include?(horse)
end

• Array#include? documentation

Late answer, but I figured it's worth keeping this updated. Expanding on Andrea Turri answer to reflect updated jQuery API and .success/.error deprecated methods.

As of jQuery 1.8.* the preferred way of doing this is to use .done() and .fail(). Jquery Docs

e.g.

$('#my_get_related_keywords').click(function() {

    var ajaxRequest = $.ajax({
        type: "POST",
        url: "HERE PUT THE PATH OF YOUR SERVICE OR PAGE",
        data: '{"HERE YOU CAN PUT DATA TO PASS AT THE SERVICE"}',
        contentType: "application/json; charset=utf-8",
        dataType: "json"});

    //When the request successfully finished, execute passed in function
    ajaxRequest.done(function(msg){
           //do something
    });

    //When the request failed, execute the passed in function
    ajaxRequest.fail(function(jqXHR, status){
        //do something else
    });
});

Is there any downside of leveraging mousedown listener to modify the href attribute with a new URL location and then let the browser figures out where it should redirect to?

It's working fine so far for me. Would like to know what the limitations are with this approach?

// Simple code snippet to demonstrate the said approach
const a = document.createElement('a');
a.textContent = 'test link';
a.href = '/haha';
a.target = '_blank';
a.rel = 'noopener';

a.onmousedown = () => {
  a.href = '/lol';
};

document.body.appendChild(a);
}

And for those of you using an anonymous expression:

await Task.Run(async () =>
{
   SQLLiteUtils slu = new SQLiteUtils();
   await slu.DeleteGroupAsync(groupname);
});

Another Alternative for those who are probing around and/or in interactive mode:

$Error[0].Exception.LoaderExceptions

Note: [0] grabs the most recent Error from the stack

Here is the solution I found:

How to fix the missing MSVCR711.dll problem

You can find MSVCR71.dll file in following location of your installed SQL Developer 2.1 directory:

sqldeveloper-2.1.0.63.10\sqldeveloper\jdk\jre\bin\MSVCR71.dll

It is a term used in dynamic languages that do not have strong typing.

The idea is that you don't need a type in order to invoke an existing method on an object - if a method is defined on it, you can invoke it.

The name comes from the phrase "If it looks like a duck and quacks like a duck, it's a duck".

Wikipedia has much more information.

I have observed that -

1. FtpwebRequest is missing.
2. As the target is FTP, so the NetworkCredential required.

I have prepared a method that works like this, you can replace the value of the variable ftpurl with the parameter TargetDestinationPath. I had tested this method on winforms application :

private void UploadProfileImage(string TargetFileName, string TargetDestinationPath, string FiletoUpload)
        {
            //Get the Image Destination path
            string imageName = TargetFileName; //you can comment this
            string imgPath = TargetDestinationPath; 

            string ftpurl = "ftp://downloads.abc.com/downloads.abc.com/MobileApps/SystemImages/ProfileImages/" + imgPath;
            string ftpusername = krayknot_DAL.clsGlobal.FTPUsername;
            string ftppassword = krayknot_DAL.clsGlobal.FTPPassword;
            string fileurl = FiletoUpload;

            FtpWebRequest ftpClient = (FtpWebRequest)FtpWebRequest.Create(ftpurl);
            ftpClient.Credentials = new System.Net.NetworkCredential(ftpusername, ftppassword);
            ftpClient.Method = System.Net.WebRequestMethods.Ftp.UploadFile;
            ftpClient.UseBinary = true;
            ftpClient.KeepAlive = true;
            System.IO.FileInfo fi = new System.IO.FileInfo(fileurl);
            ftpClient.ContentLength = fi.Length;
            byte[] buffer = new byte[4097];
            int bytes = 0;
            int total_bytes = (int)fi.Length;
            System.IO.FileStream fs = fi.OpenRead();
            System.IO.Stream rs = ftpClient.GetRequestStream();
            while (total_bytes > 0)
            {
                bytes = fs.Read(buffer, 0, buffer.Length);
                rs.Write(buffer, 0, bytes);
                total_bytes = total_bytes - bytes;
            }
            //fs.Flush();
            fs.Close();
            rs.Close();
            FtpWebResponse uploadResponse = (FtpWebResponse)ftpClient.GetResponse();
            string value = uploadResponse.StatusDescription;
            uploadResponse.Close();
        }

See our SD Thicket PHP Obfuscator for an obfuscator that works just fine with arbitrarily large sets of pages. It operates primarily by scrambling identifier names. With modest to large applications, this can make the code extremely difficult to understand, which is the entire purpose.

It doesn't waste any energy on "eval(decode(encodedprogramcode))" schemes, which a lot of PHP "obfuscators" do [these are "encoder"s, not "obfuscator"s], because any clod can find that call and execute the eval-decode himself and get the decoded code.

It uses a language-precise parser to process the PHP; it will tell you if your program is syntactically invalid. More importantly, it knows the whole language precisely; it won't get lost or confused, and it won't break your code (other that what happens if you obfuscate "incorrectly", e.g., fail to identify the public API of the code correctly).

Yes, it obfuscates identifiers identically across pages; if it didn't do that, the result wouldn't work.

Flexible Box Layout Module - 8.1. Aligning with auto margins

Auto margins on flex items have an effect very similar to auto margins in block flow:

• During calculations of flex bases and flexible lengths, auto margins are treated as 0.

• Prior to alignment via justify-content and align-self, any positive free space is distributed to auto margins in that dimension.

Therefore you could use margin-top: auto to distribute the space between the other elements and the last element.

This will position the last element at the bottom.

p:last-of-type {
  margin-top: auto;
}

.container {
  display: flex;
  flex-direction: column;
  border: 1px solid #000;
  min-height: 200px;
  width: 100px;
}
p {
  height: 30px;
  background-color: blue;
  margin: 5px;
}
p:last-of-type {
  margin-top: auto;
}

<div class="container">
  <p></p>
  <p></p>
  <p></p>
</div>

Likewise, you can also use margin-left: auto or margin-right: auto for the same alignment horizontally.

p:last-of-type {
  margin-left: auto;
}

.container {
  display: flex;
  width: 100%;
  border: 1px solid #000;
}
p {
  height: 50px;
  width: 50px;
  background-color: blue;
  margin: 5px;
}
p:last-of-type {
  margin-left: auto;
}

<div class="container">
  <p></p>
  <p></p>
  <p></p>
  <p></p>
</div>

I'm not sure what you mean by having tried it onblur, but to get the length of any string, use its .length property, so in the case of a textbox or textarea:

document.getElementById("textarea").value.length

Changing that ID, of course, to whatever the actual ID is.

Linux & all filesystems

xfs_mkfile 10240m 10Gigfile

Linux & and some filesystems (ext4, xfs, btrfs and ocfs2)

fallocate -l 10G 10Gigfile

OS X, Solaris, SunOS and probably other UNIXes

mkfile 10240m 10Gigfile

HP-UX

prealloc 10Gigfile 10737418240

Explanation

Try mkfile <size> myfile as an alternative of dd. With the -n option the size is noted, but disk blocks aren't allocated until data is written to them. Without the -n option, the space is zero-filled, which means writing to the disk, which means taking time.

mkfile is derived from SunOS and is not available everywhere. Most Linux systems have xfs_mkfile which works exactly the same way, and not just on XFS file systems despite the name. It's included in xfsprogs (for Debian/Ubuntu) or similar named packages.

Most Linux systems also have fallocate, which only works on certain file systems (such as btrfs, ext4, ocfs2, and xfs), but is the fastest, as it allocates all the file space (creates non-holey files) but does not initialize any of it.

If one of the tables M, S, D, or H has more than one row for a given Id (if just the Id column is not the Primary Key), then the query would result in "duplicate" rows. If you have more than one row for an Id in a table, then the other columns, which would uniquely identify a row, also must be included in the JOIN condition(s).

Related Question on MSDN Forum

Its an XML namespace. It is required when you use XHTML 1.0 or 1.1 doctypes or application/xhtml+xml mimetypes.

You should be using HTML5 doctype, then you don't need it for text/html. Better start from template like this :

<!DOCTYPE html>
<html>
    <head>
        <meta charset=utf-8 />
        <title>domcument title</title>
        <link rel="stylesheet" href="/stylesheet.css" type="text/css" />
    </head>
    <body>
            <!-- your html content -->
            <script src="/script.js"></script>
    </body>
</html>

When you have put your Doctype straight - do and validate you html and your css .
That usually will sove you layout issues.

This is, IMHO, the most generic and robust solution (if your actions are user-triggered, eg 'user clicks on a button'):

• the first time a handler is called check WHO triggered it:
  • if a user tiggered it - do your stuff, and then trigger it again (if you want) - programmatically
  • otherwise - do nothing (= "continue default")

As an example, note this elegant solution to adding "Are you sure?" popup to any button just by decorating a button with an attribute. We will conditionally continue default behavior if the user doesn't opt out.

1. Let's add to every button that we want an "are you sure" popup a warning text:

<button class="btn btn-success-outline float-right" type="submit"  ays_text="You will lose any unsaved changes... Do you want to continue?"                >Do something dangerous</button>

2. Attach handlers to ALL such buttons:

$('button[ays_text]').click(function (e, from) {
    if (from == null) {  // user clicked it!
        var btn = $(this);
        e.preventDefault();
        if (confirm() == true) {
            btn.trigger('click', ['your-app-name-here-or-anything-that-is-not-null']);
        }
    }
    // otherwise - do nothing, ie continue default
});

That's it.

As of October 2015, WP 4.3.1 I have found only two plugins actually affecting image locations as in “folders & subfolders”:

• Custom Upload Dir, but as the name says, just on upload. You can work from your %post_slug% or %categories%, upload your images in the context of these post/pages, and this tool will form subfolders from it. Which is great, SEO-wise.

  Or you just even ignore all that and mandate under “Build a path template” i.e. travels/france/paris-at-night to upload to that subdir of your WP-Uploads folder. (Of course you'd have to keep changing for the uploads to follow. Limiting my overall faith, that this is a stable long-term tool, despite 10.000+ active installs).

• Media File Manager allows to move already uploaded images and changes the paths in posts and pages using them accordingly. Its interface reminds of “Norton Commander 1.0” but it does the job. (Except for folder renames and deletes. So if you want to rename, better move images to a newly namend folder, then manually deleting the old.)

All of the following do NOT do the job:

• WP Media Folder is NOT changing actual direcory location, thus not actually changing paths to your images thus also not affecting image URLs. Despite its name, Folder is just their visualisation of yet-another-taxonomy. I invested $19 to learn that.

• Enhance Media Library is big, free and very popular (wordpress counts 40.000 installs) but is also not changing physical location and (thus) URLs. ? Thus the accepted answer is in my opinion wrong.

• Media File Manager advanced appears gone and is deemed dangerous!

You're thinking about this the wrong way. You're thinking in logical steps each time cin or getline is used. Ex. First ask for a number, then ask for a name. That is the wrong way to think about cin. So you run into a race condition because you assume the stream is clear each time you ask for a input.

If you write your program purely for input you'll find the problem:

void main(void)
{
    double num;
    string mystr;

    cin >> num;
    getline(cin, mystr);

    cout << "num=" << num << ",mystr=\'" << mystr << "\'" << endl;
}

In the above, you are thinking, "first get a number." So you type in 123 press enter, and your output will be num=123,mystr=''. Why is that? It's because in the stream you have 123\n and the 123 is parsed into the num variable while \n is still in the stream. Reading the doc for getline function by default it will look in the istream until a \n is encountered. In this example, since \n is in the stream, it looks like it "skipped" it but it worked properly.

For the above to work, you'll have to enter 123Hello World which will properly output num=123,mystr='Hello World'. That, or you put a cin.ignore between the cin and getline so that it'll break into logical steps that you expect.

This is why you need the ignore command. Because you are thinking of it in logical steps rather than in a stream form so you run into a race condition.

Take another code example that is commonly found in schools:

void main(void)
{
    int age;
    string firstName;
    string lastName;

    cout << "First name: ";
    cin >> firstName;

    cout << "Last name: ";
    cin >> lastName;

    cout << "Age: ";
    cin >> age;

    cout << "Hello " << firstName << " " << lastName << "! You are " << age << " years old!" << endl;
}

The above seems to be in logical steps. First ask for first name, last name, then age. So if you did John enter, then Doe enter, then 19 enter, the application works each logic step. If you think of it in "streams" you can simply enter John Doe 19 on the "First name:" question and it would work as well and appear to skip the remaining questions. For the above to work in logical steps, you would need to ignore the remaining stream for each logical break in questions.

Just remember to think of your program input as it is reading from a "stream" and not in logical steps. Each time you call cin it is being read from a stream. This creates a rather buggy application if the user enters the wrong input. For example, if you entered a character where a cin >> double is expected, the application will produce a seemingly bizarre output.

The below Method will Return you a value between 10000000000 to 9999999999

long min = 1000000000L
long max = 9999999999L    

public static long getRandomNumber(long min, long max){

    Random random = new Random();         
    return random.nextLong() % (max - min) + max;

}

Here's a quick one-line hack that I occasionally use to temporarily turn on log4j debug logging in a JUnit test:

Logger.getRootLogger().setLevel(Level.DEBUG);

or if you want to avoid adding imports:

org.apache.log4j.Logger.getRootLogger().setLevel(
      org.apache.log4j.Level.DEBUG);

Note: this hack doesn't work in log4j2 because setLevel has been removed from the API, and there doesn't appear to be equivalent functionality.

In response to the answer by Tatu I have created a quick jsFiddle for showcasing his solution:

http://jsfiddle.net/duwood/sTX7y/

In my case it was not connected to 'final', but to the issue mentioned in @NemanjaKovacevic comment to @aga answer. I was setting a layoutManager on data load and that was the cause of the same crash. After moving the layoutManager setup to onCreateView of my fragment the issue was fixed.

Something like this:

Here is a link from developer.nokia.com wiki pages, which explains how to install Windows Phone 8 SDK on a Virtual Machine with Working Emulator

And another link here

AFAIK, it is not possible to directly install WP8 SDK in Windows 7, because WP8 sdk is VS 2012 supported and also its emulator works on a Hyper-V (which is integrated into the Windows 8).

If both your client and service is installed on the same machine, and you are facing this problem with the correct (read: tried and tested elsewhere) client and service configurations, then this might be worth checking.

Check host entries in your host file

%windir%/system32/drivers/etc/hosts

Check to see if you are accessing your web service with a hostname, and that same hostname has been associated with an IP address in the hosts file mentioned above. If yes, NTLM/Windows credentials will NOT be passed from the client to the service as any request for that hostname will be routed again at the machine level.

Try either of the following

• Remove the host entry of that hostname from the hosts file
OR
• If removing host entry is not possible, then try accessing your service with another hostname. You might also try with IP address instead of hostname

Edit: Somehow the above situation is relevant on a load-balanced scenario. However, if removing the host entries is not possible, then disabling loop back check on the machine will help. Refer method 2 in the article https://support.microsoft.com/en-us/kb/896861

I feel we had a related discussion earlier: How to upload preview image before upload through JavaScript

In order to get rid of duplicates, you can group by drinks.id. But that way you'll get only one photo for each drinks.id (which photo you'll get depends on database internal implementation).

Though it is not documented, in case of MySQL, you'll get the photo with lowest id (in my experience I've never seen other behavior).

SELECT name, price, photo 
FROM drinks, drinks_photos 
WHERE drinks.id = drinks_id
GROUP BY drinks.id

var str = "hello,how,are,you,today?";
var pieces = str.split(/[\s,]+/);

At this point, pieces is an array and pieces.length contains the size of the array so to get the last element of the array, you check pieces[pieces.length-1]. If there are no commas or spaces it will simply output the string as it was given.

alert(pieces[pieces.length-1]); // alerts "today?"
