This post is high up when you google that error message, which I got when installing security patch KB4505224 on SQL Server 2017 Express i.e. None of the above worked for me, but did consume several hours trying.

The solution for me, partly from here was:

1. uninstall SQL Server
2. in Regional Settings / Management / System Locale, "Beta: UTF-8 support" should be OFF
3. re-install SQL Server
4. Let Windows install the patch.

And all was well.

More on this here.

Nor Kelsey, nor Brendan solutions does not works for me in Visual Studio 2015 Community.

Here is my brief steps how to create service with installer:

1. Run Visual Studio, Go to File->New->Project
2. Select .NET Framework 4, in 'Search Installed Templates' type 'Service'
3. Select 'Windows Service'. Type Name and Location. Press OK.
4. Double click Service1.cs, right click in designer and select 'Add Installer'
5. Double click ProjectInstaller.cs. For serviceProcessInstaller1 open Properties tab and change 'Account' property value to 'LocalService'. For serviceInstaller1 change 'ServiceName' and set 'StartType' to 'Automatic'.

6. Double click serviceInstaller1. Visual Studio creates serviceInstaller1_AfterInstall event. Write code:

   private void serviceInstaller1_AfterInstall(object sender, InstallEventArgs e)
   {
       using (System.ServiceProcess.ServiceController sc = new 
       System.ServiceProcess.ServiceController(serviceInstaller1.ServiceName))
       {
           sc.Start();
       }
   }
   

7. Build solution. Right click on project and select 'Open Folder in File Explorer'. Go to bin\Debug.

8. Create install.bat with below script:

   :::::::::::::::::::::::::::::::::::::::::
   :: Automatically check & get admin rights
   :::::::::::::::::::::::::::::::::::::::::
   @echo off
   CLS 
   ECHO.
   ECHO =============================
   ECHO Running Admin shell
   ECHO =============================
   
   :checkPrivileges 
   NET FILE 1>NUL 2>NUL
   if '%errorlevel%' == '0' ( goto gotPrivileges ) else ( goto getPrivileges ) 
   
   :getPrivileges 
   if '%1'=='ELEV' (shift & goto gotPrivileges)  
   ECHO. 
   ECHO **************************************

   ECHO UAC.ShellExecute "!batchPath!", "ELEV", "", "runas", 1 >> "%temp%\OEgetPrivileges.vbs" 
   "%temp%\OEgetPrivileges.vbs" 
   exit /B

   cd /d %~dp0
   %windir%\Microsoft.NET\Framework\v4.0.30319\InstallUtil /i "WindowsService1.exe"
   pause
   

9. Create uninstall.bat file (change in pen-ult line /i to /u)
10. To install and start service run install.bat, to stop and uninstall run uninstall.bat

The installation of these tools may vary on different OS.

Under Windows, node-sass currently supports VS2015 by default, if you only have VS2013 in your box and meet any error while running the command, you can define the version of VS by adding: --msvs_version=2013. This is noted on the node-sass npm page.

So, the safe command line that works on Windows with VS2013 is: npm install --msvs_version=2013 gulp node-sass gulp-sass

Say the remote is origin and the branch is master, and say you already have master checked out, might try the following:

git fetch origin
git reset --hard origin/master

This basically just takes the current branch and points it to the HEAD of the remote branch.

WARNING: As stated in the comments, this will throw away your local changes and overwrite with whatever is on the origin.

Or you can use the plumbing commands to do essentially the same:

git fetch <remote>
git update-ref refs/heads/<branch> $(git rev-parse <remote>/<branch>)
git reset --hard

EDIT: I'd like to briefly explain why this works.

The .git folder can hold the commits for any number of repositories. Since the commit hash is actually a verification method for the contents of the commit, and not just a randomly generated value, it is used to match commit sets between repositories.

A branch is just a named pointer to a given hash. Here's an example set:

$ find .git/refs -type f
.git/refs/tags/v3.8
.git/refs/heads/master
.git/refs/remotes/origin/HEAD
.git/refs/remotes/origin/master

Each of these files contains a hash pointing to a commit:

$ cat .git/refs/remotes/origin/master
d895cb1af15c04c522a25c79cc429076987c089b

These are all for the internal git storage mechanism, and work independently of the working directory. By doing the following:

git reset --hard origin/master

git will point the current branch at the same hash value that origin/master points to. Then it forcefully changes the working directory to match the file structure/contents at that hash.

To see this at work go ahead and try out the following:

git checkout -b test-branch
# see current commit and diff by the following
git show HEAD
# now point to another location
git reset --hard <remote>/<branch>
# see the changes again
git show HEAD

I also have the same error. I have updated the jackson library version and error has gone.

<!-- Jackson to convert Java object to Json -->

        </dependency>
    </dependencies>

and also check your data classes that have you created getters and setters for all the properties.

I've used a DOS command line to do this. Two lines, actually. The first one to make the "current directory" the folder where the file is - or the root folder of a group of folders where the file can be. The second line does the search.

CD C:\TheFolder
C:\TheFolder>FINDSTR /L /S /I /N /C:"TheString" *.PRG

You can find details about the parameters at this link.

Hope it helps!

Other solutions are good enough to answer your query. However, if you are looking for just one command to do that for you -

Create a file name "run", in directory where your Java files are. And save this in your file -

javac "$1.java"
if [ $? -eq 0 ]; then
  echo "--------Run output-------"
  java "$1"
fi

give this file run permission by running -

chmod 777 

Now you can run any of your files by merely running -

./run <yourfilename> (don't add .java in filename)

The first answer that uses eyed3 is outdated so here is an updated version of it.

Reading tags from an mp3 file:

 import eyed3

 audiofile = eyed3.load("some/file.mp3")
 print(audiofile.tag.artist)
 print(audiofile.tag.album)
 print(audiofile.tag.album_artist)
 print(audiofile.tag.title)
 print(audiofile.tag.track_num)

An example from the website to modify tags:

 import eyed3

 audiofile = eyed3.load("some/file.mp3")
 audiofile.tag.artist = u"Integrity"
 audiofile.tag.album = u"Humanity Is The Devil"
 audiofile.tag.album_artist = u"Integrity"
 audiofile.tag.title = u"Hollow"
 audiofile.tag.track_num = 2

An issue I encountered while trying to use eyed3 for the first time had to do with an import error of libmagic even though it was installed. To fix this install the magic-bin whl from here

Sorry for reviving really old question but as it is listed among first google search results I assume that some people keep landing here.

Among a lot of answers, some of them really valuable and well explained, I would like to add a different point of vue as, to me, the problem has not be well identified.

You are declaring a variable which stores data, you need it to be able to change by adding items to it ? So you shouldn't use declare it as IEnumerable.

As proposed by @NightOwl888

For this example, just declare IList instead of IEnumerable: IList items = new T[]{new T("msg")}; items.Add(new T("msg2"));

Trying to bypass the declared interface limitations only shows that you made the wrong choice. Beyond this, all methods that are proposed to implement things that already exists in other implementations should be deconsidered. Classes and interfaces that let you add items already exists. Why always recreate things that are already done elsewhere ?

This kind of consideration is a goal of abstracting variables capabilities within interfaces.

TL;DR : IMO these are cleanest ways to do what you need :

// 1st choice : Changing declaration
IList<T> variable = new T[] { };
variable.Add(new T());

// 2nd choice : Changing instantiation, letting the framework taking care of declaration
var variable = new List<T> { };
variable.Add(new T());

When you'll need to use variable as an IEnumerable, you'll be able to. When you'll need to use it as an array, you'll be able to call 'ToArray()', it really always should be that simple. No extension method needed, casts only when really needed, ability to use LinQ on your variable, etc ...

Stop doing weird and/or complex things because you only made a mistake when declaring/instantiating.

Try:

my_command || { echo 'my_command failed' ; exit 1; }

Four changes:

• Change && to ||
• Use { } in place of ( )
• Introduce ; after exit and
• spaces after { and before }

Since you want to print the message and exit only when the command fails ( exits with non-zero value) you need a || not an &&.

cmd1 && cmd2

will run cmd2 when cmd1 succeeds(exit value 0). Where as

cmd1 || cmd2

will run cmd2 when cmd1 fails(exit value non-zero).

Using ( ) makes the command inside them run in a sub-shell and calling a exit from there causes you to exit the sub-shell and not your original shell, hence execution continues in your original shell.

To overcome this use { }

The last two changes are required by bash.

jQuery.ajax attempts to convert the response body depending on the specified dataType parameter or the Content-Type header sent by the server. If the conversion fails (e.g. if the JSON/XML is invalid), the error callback is fired.

Your AJAX code contains:

dataType: "json"

In this case jQuery:

Evaluates the response as JSON and returns a JavaScript object. […] The JSON data is parsed in a strict manner; any malformed JSON is rejected and a parse error is thrown. […] an empty response is also rejected; the server should return a response of null or {} instead.

Your server-side code returns HTML snippet with 200 OK status. jQuery was expecting valid JSON and therefore fires the error callback complaining about parseerror.

The solution is to remove the dataType parameter from your jQuery code and make the server-side code return:

Content-Type: application/javascript

alert("Record Deleted");

But I would rather suggest returning a JSON response and display the message inside the success callback:

Content-Type: application/json

{"message": "Record deleted"}

This is a slightly more general answer with more explanation for future viewers.

Add a text changed listener

If you want to find the text length or do something else after the text has been changed, you can add a text changed listener to your edit text.

EditText editText = (EditText) findViewById(R.id.testEditText);
editText.addTextChangedListener(new TextWatcher() {

    @Override
    public void beforeTextChanged(CharSequence charSequence, int start, int count, int after) {

    }

    @Override
    public void onTextChanged(CharSequence charSequence, int start, int before, int count)  {

    }

    @Override
    public void afterTextChanged(Editable editable) {

    }
});

The listener needs a TextWatcher, which requires three methods to be overridden: beforeTextChanged, onTextChanged, and afterTextChanged.

Counting the characters

You can get the character count in onTextChanged or beforeTextChanged with

charSequence.length()

or in afterTextChanged with

editable.length()

Meaning of the methods

The parameters are a little confusing so here is a little extra explanation.

beforeTextChanged

beforeTextChanged(CharSequence charSequence, int start, int count, int after)

• charSequence: This is the text content before the pending change is made. You should not try to change it.
• start: This is the index of where the new text will be inserted. If a range is selected, then it is the beginning index of the range.
• count: This is the length of selected text that is going to be replaced. If nothing is selected then count will be 0.
• after: this is the length of the text to be inserted.

onTextChanged

onTextChanged(CharSequence charSequence, int start, int before, int count)

• charSequence: This is the text content after the change was made. You should not try to modify this value here. Modify the editable in afterTextChanged if you need to.
• start: This is the index of the start of where the new text was inserted.
• before: This is the old value. It is the length of previously selected text that was replaced. This is the same value as count in beforeTextChanged.
• count: This is the length of text that was inserted. This is the same value as after in beforeTextChanged.

afterTextChanged

afterTextChanged(Editable editable)

Like onTextChanged, this is called after the change has already been made. However, now the text may be modified.

• editable: This is the editable text of the EditText. If you change it, though, you have to be careful not to get into an infinite loop. See the documentation for more details.

Adding your favicon simply into to the public folder should do. Make sure the favicon is named as favicon.ico.

Using ng-selected for selected value. I Have successfully implemented code in AngularJS v1.3.2

<select ng-model="objBillingAddress.StateId"  >_x000D_
   <option data-ng-repeat="c in States" value="{{c.StateId}}" ng-selected="objBillingAddress.BillingStateId==c.StateId">{{c.StateName}}</option>_x000D_

I faced the same issue and solved using the below steps. Go to Windows->preferences->Editors->File Associations

Here click on Add then type .class click on OK

again click on Add then type .classwithoughtsource click on OK

Now you will be able to see JadClipse option under Java section in Windows->Preferences

Please provide the path of jad.exe file as shown below.

Path for Decompiler-C:\Users\ahr\Documents\eclipse-jee-galileo-SR2-win32\jad.exe Directory for temporary Files-C:\Users\ahr.net.sf.jadclipse

click on Apply

Now you should be able to see the classfiles in proper format.

The termination of an array of characters with a null character is just a convention that is specifically for strings in C. You are dealing with something completely different -- an array of character pointers -- so it really has no relation to the convention for C strings. Sure, you could choose to terminate it with a null pointer; that perhaps could be your convention for arrays of pointers. There are other ways to do it. You can't ask people how it "should" work, because you're assuming some convention that isn't there.

The user's input will always be given to you in the form of a string of characters... if you want to convert the user's input from a string to an integer, you'll need to supply the code to do that. If the user types in a number (e.g. "1"), you can pass the string to atoi() to get the integer corresponding to the string. If the user types in an english string (e.g. "EASY") then you'll need to check for that string (e.g. with strcmp()) and assign the appropriate integer value to your variable based on which check matches. Once you have an integer value that was derived from the user's input string, you can pass it into the switch() statement as usual.

From the @LearnRPG answer but with 1.0:

 // send to current request socket client
 socket.emit('message', "this is a test");

 // sending to all clients, include sender
 io.sockets.emit('message', "this is a test"); //still works
 //or
 io.emit('message', 'this is a test');

 // sending to all clients except sender
 socket.broadcast.emit('message', "this is a test");

 // sending to all clients in 'game' room(channel) except sender
 socket.broadcast.to('game').emit('message', 'nice game');

 // sending to all clients in 'game' room(channel), include sender
 // docs says "simply use to or in when broadcasting or emitting"
 io.in('game').emit('message', 'cool game');

 // sending to individual socketid, socketid is like a room
 socket.broadcast.to(socketid).emit('message', 'for your eyes only');

To answer @Crashalot comment, socketid comes from:

var io = require('socket.io')(server);
io.on('connection', function(socket) { console.log(socket.id); })

(This might be the wrong thread, as your problem seems more specific, but it's the thread that I found when searching for the issue's keywords)

Despite all good hints, the only thing that helped me, and that I'd like to share just in case, if everything else does not work :

Remove your .gradle directory in your home directory and have it re-build/re-downloaded for you by Android Studio.

Fixed all kinds of weird errors for me that neither were fixable by re-installing Android Studio itself nor the SDK.

The object name is not very important. what you should be focusing at is the variable that stores the lineedit object (le) and your pushbutton object(pb)

QObject(self.pb, SIGNAL("clicked()"), self.button_clicked)

def button_clicked(self):
  self.le.setText("shost")

I think this is what you want. I hope i got your question correctly :)

a function to house the print trigger...

function printTrigger(elementId) {
    var getMyFrame = document.getElementById(elementId);
    getMyFrame.focus();
    getMyFrame.contentWindow.print();
}

an button to give the user access...

(an onClick on an a or button or input or whatever you wish)

<input type="button" value="Print" onclick="printTrigger('iFramePdf');" />
an iframe pointing to your PDF...

<iframe id="iFramePdf" src="myPdfUrl.pdf" style="dispaly:none;"></iframe>

It seems that

{
   "start_windows": "set NODE_ENV=test"
}

is not working for me. I'm currently trying this on my Windows machine. When I hit:

npm run start_windows

it would execute on the console without errors but when I try to echo

echo %NODE_ENV%

nothing comes out of it, meaning it does not exist and it wasn't set at all...

The reason Herb said what he said is because of cases like this.

Let's say I have function A which calls function B, which calls function C. And A passes a string through B and into C. A does not know or care about C; all A knows about is B. That is, C is an implementation detail of B.

Let's say that A is defined as follows:

void A()
{
  B("value");
}

If B and C take the string by const&, then it looks something like this:

void B(const std::string &str)
{
  C(str);
}

void C(const std::string &str)
{
  //Do something with `str`. Does not store it.
}

All well and good. You're just passing pointers around, no copying, no moving, everyone's happy. C takes a const& because it doesn't store the string. It simply uses it.

Now, I want to make one simple change: C needs to store the string somewhere.

void C(const std::string &str)
{
  //Do something with `str`.
  m_str = str;
}

Hello, copy constructor and potential memory allocation (ignore the Short String Optimization (SSO)). C++11's move semantics are supposed to make it possible to remove needless copy-constructing, right? And A passes a temporary; there's no reason why C should have to copy the data. It should just abscond with what was given to it.

Except it can't. Because it takes a const&.

If I change C to take its parameter by value, that just causes B to do the copy into that parameter; I gain nothing.

So if I had just passed str by value through all of the functions, relying on std::move to shuffle the data around, we wouldn't have this problem. If someone wants to hold on to it, they can. If they don't, oh well.

Is it more expensive? Yes; moving into a value is more expensive than using references. Is it less expensive than the copy? Not for small strings with SSO. Is it worth doing?

It depends on your use case. How much do you hate memory allocations?

You should be able to get the text using getText() (for the option element you got using getFirstSelectedOption()):

Select select = new Select(driver.findElement(By.xpath("//select")));
WebElement option = select.getFirstSelectedOption();
String defaultItem = option.getText();
System.out.println(defaultItem );

i called activity_name.this.finish() after starting new intent and it worked for me.

I tried "FLAG_ACTIVITY_CLEAR_TOP" and "FLAG_ACTIVITY_NEW_TASK"

But it won't work for me... I am not suggesting this solution for use but if setting flag won't work for you than you can try this..But still i recommend don't use it

Actually, for the configuration of the machine, just open the .vmx file with a text editor (e.g. notepad, gedit, etc.). You will be able to see the OS type, memsize, ethernet.connectionType, and other settings. Then when you make your machine, just look in the text editor for the corresponding settings. When it asks for the disk, select the .vmdk disk as mentioned above.

This answer builds on the solution from @iain-elder, which works well except for the large database case (as pointed out in his solution). The entire table needs to fit in your system's memory, and for me this was not an option. I suspect the best solution would use the System.Data.SqlClient.SqlDataReader and a custom CSV serializer (see here for an example) or another language with an MS SQL driver and CSV serialization. In the spirit of the original question which was probably looking for a no dependency solution, the PowerShell code below worked for me. It is very slow and inefficient especially in instantiating the $data array and calling Export-Csv in append mode for every $chunk_size lines.

$chunk_size = 10000
$command = New-Object System.Data.SqlClient.SqlCommand
$command.CommandText = "SELECT * FROM <TABLENAME>"
$command.Connection = $connection
$connection.open()
$reader = $command.ExecuteReader()

$read = $TRUE
while($read){
    $counter=0
    $DataTable = New-Object System.Data.DataTable
    $first=$TRUE;
    try {
        while($read = $reader.Read()){

            $count = $reader.FieldCount
            if ($first){
                for($i=0; $i -lt $count; $i++){
                    $col = New-Object System.Data.DataColumn $reader.GetName($i)
                    $DataTable.Columns.Add($col)
                }
                $first=$FALSE;
            }

            # Better way to do this?
            $data=@()
            $emptyObj = New-Object System.Object
            for($i=1; $i -le $count; $i++){
                $data +=  $emptyObj
            }

            $reader.GetValues($data) | out-null
            $DataRow = $DataTable.NewRow()
            $DataRow.ItemArray = $data
            $DataTable.Rows.Add($DataRow)
            $counter += 1
            if ($counter -eq $chunk_size){
                break
            }
        }
        $DataTable | Export-Csv "output.csv" -NoTypeInformation -Append
    }catch{
        $ErrorMessage = $_.Exception.Message
        Write-Output $ErrorMessage
        $read=$FALSE
        $connection.Close()
        exit
    }
}
$connection.close()

d = {} will create a new instance for d but all other references will still point to the old contents. d.clear() will reset the contents, but all references to the same instance will still be correct.

Have you tried layerGroup yet?

Docs here https://leafletjs.com/reference-1.2.0.html#layergroup

Just create a layer, add all marker to this layer, then you can find and destroy marker easily.

var markers = L.layerGroup()
const marker = L.marker([], {})
markers.addLayer(marker)

Intellij User, make sure you have 3 things,

1. Lombok dependency

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.8</version>
            <scope>provided</scope>
        </dependency>

2. IntelliJ plugin for Lombok

3. Lombok annotation, like @Getter @Setter (make sure it is coming from lombok and not from somewhere else)

and it should work.

I had this problem with my datasource in WildFly and Tomcat, connecting to a Oracle 10g.

I found that under certain conditions the statement wasn't closed even when the statement.close() was invoked. The problem was with the Oracle Driver we were using: ojdbc7.jar. This driver is intended for Oracle 12c and 11g, and it seems has some issues when is used with Oracle 10g, so I downgrade to ojdbc5.jar and now everything is running fine.

If you're using the command-line tools, running git --version should give you the version number.

As previously stated, it's not directly possible, but you can set up Apache or nginx + SSL on a EC2 instance, CNAME your desired domain to that, and reverse-proxy to the (non-custom domain) S3 URLs.

If you want a proper button then you'll need some javascript. Something like this (needs some work on the styling but you get the gist). Wouldn't bother using jquery for something so trivial to be honest.

<html>
<head>
<style type="text/css">
.on { 
border:1px outset;
color:#369;
background:#efefef; 
}

.off {
border:1px outset;
color:#369;
background:#f9d543; 
}
</style>

<script language="javascript">
function togglestyle(el){
    if(el.className == "on") {
        el.className="off";
    } else {
        el.className="on";
    }

As mentioned by @leocaseiro on github issue.

I found 3 solutions for those who are looking for easy fixes.

1) Moving from ngAfterViewInit to ngAfterContentInit

2) Moving to ngAfterViewChecked combined with ChangeDetectorRef as suggested on #14748 (comment)

3) Keep with ngOnInit() but call ChangeDetectorRef.detectChanges() after your changes.

This works for both git log and gitk - the 2 most common ways of viewing history.
You don't need to use the whole name:

git log --author="Jon"

will match a commit made by "Jonathan Smith"

git log --author=Jon

and

git log --author=Smith

would also work. The quotes are optional if you don't need any spaces.

Add --all if you intend to search all branches and not just the current commit's ancestors in your repo.

You can also easily match on multiple authors as regex is the underlying mechanism for this filter. So to list commits by Jonathan or Adam, you can do this:

git log --author="\(Adam\)\|\(Jon\)"

In order to exclude commits by a particular author or set of authors using regular expressions as noted in this question, you can use a negative lookahead in combination with the --perl-regexp switch:

git log --author='^(?!Adam|Jon).*$' --perl-regexp

Alternatively, you can exclude commits authored by Adam by using bash and piping:

git log --format='%H %an' | 
  grep -v Adam | 
  cut -d ' ' -f1 | 
  xargs -n1 git log -1

If you want to exclude commits commited (but not necessarily authored) by Adam, replace %an with %cn. More details about this are in my blog post here: http://dymitruk.com/blog/2012/07/18/filtering-by-author-name/

You need to check your project settings, under C++, check include directories and make sure it points to where GameEngine.h resides, the other issue could be that GameEngine.h is not in your source file folder or in any include directory and resides in a different folder relative to your project folder. For instance you have 2 projects ProjectA and ProjectB, if you are including GameEngine.h in some source/header file in ProjectA then to include it properly, assuming that ProjectB is in the same parent folder do this:

include "../ProjectB/GameEngine.h"

This is if you have a structure like this:

Root\ProjectA

Root\ProjectB <- GameEngine.h actually lives here

It depends on what your local OS is.

If your local OS is Unix-like, then try:

scp username@remoteHost:/remote/dir/file.txt /local/dir/

If your local OS is Windows ,then you should use pscp.exe utility. For example, below command will download file.txt from remote to D: disk of local machine.

pscp.exe username@remoteHost:/remote/dir/file.txt d:\

It seems your Local OS is Unix, so try the former one.

For those who don't know what pscp.exe is and don't know where it is, you can always go to putty official website to download it. And then open a CMD prompt, go to the pscp.exe directory where you put it. Then execute the command as provided above

Firstly, the level name to use is FINE, not DEBUG. Let's assume for a minute that DEBUG is actually valid, as it makes the following explanation make a bit more sense...

In the Handler specific properties section, you're setting the logging level for those handlers to DEBUG. This means the handlers will handle any log messages with the DEBUG level or higher. It doesn't necessarily mean any DEBUG messages are actually getting passed to the handlers.

In the Facility specific properties section, you're setting the logging level for a few explicitly-named loggers to DEBUG. For those loggers, anything at level DEBUG or above will get passed to the handlers.

The default logging level is INFO, and apart from the loggers mentioned in the Facility specific properties section, all loggers will have that level.

If you want to see all FINE messages, add this:

.level = FINE

However, this will generate a vast quantity of log messages. It's probably more useful to set the logging level for your code:

your.package.level = FINE

See the Tomcat 6/Tomcat 7 logging documentation for more information. The example logging.properties file shown there uses FINE instead of DEBUG:

...
1catalina.org.apache.juli.FileHandler.level = FINE
...

and also gives you examples of setting additional logging levels:

# For example, set the com.xyz.foo logger to only log SEVERE
# messages:
#org.apache.catalina.startup.ContextConfig.level = FINE
#org.apache.catalina.startup.HostConfig.level = FINE
#org.apache.catalina.session.ManagerBase.level = FINE

T = map(lambda i: L[i], Idx)

You can use :

composer self-update --2

To update to 2.0.8 version (Latest stable version)

df.apply(pd.value_counts).fillna(0)

value_counts - Returns object containing counts of unique values

apply - count frequency in every column. If you set axis=1, you get frequency in every row

fillna(0) - make output more fancy. Changed NaN to 0

Try Handle. Filemon & Regmon are also great for trying to figure out what the duce program foo is doing to your system.

String.Concat transforms DBNull and null values to an empty string.

public string GetCustomerNumber(Guid id)
{
   object accountNumber =  
          (object)DBSqlHelperFactory.ExecuteScalar(connectionStringSplendidCRM, 
                                CommandType.StoredProcedure, 
                                "spx_GetCustomerNumber", 
                                new SqlParameter("@id", id));

    return String.Concat(accountNumber);

 }

However, I think you lose something on code understandability

If you have a form as such:

<form id="myform">
...
</form>

You can use the following jQuery code to do something before the form is submitted:

$('#myform').submit(function() {
    // DO STUFF...
    return true; // return false to cancel form action
});

The tag is fine to use without an href attribute. Contrary to many of the answers here, there are actually standard reasons for creating an anchor when there is no href. Semantically, "a" means an anchor or a link. If you use it for anything following that meaning, then you are fine.

One standard use of the a tag without an href is to create named links. This allows you to use an anchor with name=blah and later on you can create an anchor with href=#blah to link to the named section of the current page. However, this has been deprecated because you can also use IDs in the same manner. As an example, you could use a header tag with id=header and later you could have an anchor pointing to href=#header.

My point, however, is not to suggest using the name property. Only to provide one use case where you don't need an href, and therefore reasoning why it is not required.

In the current C++0x standard you can explicitly disable default constructors with the delete syntax, e.g.

MyClass() = delete;

Gcc 4.6 is the first version to support this syntax, so maybe that is the problem...

Once the table is created -

select 
    A.id, A.SomeNumt, SUM(B.SomeNumt) as sum
    from @t A, @t B where A.id >= B.id
    group by A.id, A.SomeNumt

order by A.id

This gets a little complicated. These objects are custom classes or structs, and looking inside them is not as easy on Xcode as in other development environments.

If I were you, I'd NSLog the values you want to see, with some description.

i.e:

NSLog(@"Description of object & time: %i", indexPath.row);

By default you use curl without explicitly saying which request method to use. If you just pass in a HTTP URL like curl http://example.com it will use GET. If you use -d or -F curl will use POST, -I will cause a HEAD and -T will make it a PUT.

If for whatever reason you're not happy with these default choices that curl does for you, you can override those request methods by specifying -X [WHATEVER]. This way you can for example send a DELETE by doing curl -X DELETE [URL].

It is thus pointless to do curl -X GET [URL] as GET would be used anyway. In the same vein it is pointless to do curl -X POST -d data [URL]... But you can make a fun and somewhat rare request that sends a request-body in a GET request with something like curl -X GET -d data [URL].

Digging deeper

curl -GET (using a single dash) is just wrong for this purpose. That's the equivalent of specifying the -G, -E and -T options and that will do something completely different.

There's also a curl option called --get to not confuse matters with either. It is the long form of -G, which is used to convert data specified with -d into a GET request instead of a POST.

(I subsequently used my own answer here to populate the curl FAQ to cover this.)

Warnings

Modern versions of curl will inform users about this unnecessary and potentially harmful use of -X when verbose mode is enabled (-v) - to make users aware. Further explained and motivated in this blog post.

-G converts a POST + body to a GET + query

You can ask curl to convert a set of -d options and instead of sending them in the request body with POST, put them at the end of the URL's query string and issue a GET, with the use of `-G. Like this:

curl -d name=daniel -d grumpy=yes -G https://example.com/

You can pass an object which is refering to all the values at a particular index.

import java.util.ArrayList;

public class HelloWorld{

 public static void main(String []args){


ArrayList<connect> a=new ArrayList<connect>();

a.add(new connect(100,100,100,100,100));

System.out.println(a.get(0).p1);

System.out.println(a.get(0).p2);

System.out.println(a.get(0).p3);
}

}

class connect
{
int p1,p2,p3,p4,p5;

connect(int a,int b,int c,int d,int e)
{

this.p1=a;

this.p2=b;

this.p3=c;

this.p4=d;

this.p5=e;
}

}

Later to get a particular value at a specific index, you can do this:

a.get(0).p1;

a.get(0).p2;

a.get(0).p3;.............

and so on.

I just had only getters , after adding setters too , problems resolved.

As for me on windows 2012r2 it's start to work only after I reinstall pgAdmin 4 to folder c:\pgAdmin4. With out spaces and any special chars. And all so I give full permission to this folder in NTFS.

You have to self join stuff and match name and city. Then group by count.

select 
   s.id, s.name, s.city 
from stuff s join stuff p ON (
   s.name = p.city OR s.city = p.name
)
group by s.name having count(s.name) > 1

I've been working kind of similar to this and I have some code that might help you. The live example is here and below, is the code I'm using for you to have it as reference.

create-page.php

<?php

// Session is started.
session_start();

// Name of the template file.
$template_file = 'couples-template.php';

// Root folder if working in subdirectory. Name is up to you ut must match with server's folder.
$base_path = '/couple/';

// Path to the directory where you store the "couples-template.php" file.
$template_path = '../template/';

// Path to the directory where php will store the auto-generated couple's pages.
$couples_path = '../couples/';

// Posted data.
$data['groom-name'] = str_replace(' ', '', $_POST['groom-name']);
$data['bride-name'] = str_replace(' ', '', $_POST['bride-name']);
// $data['groom-surname'] = $_POST['groom-surname'];
// $data['bride-surname'] = $_POST['bride-surname'];
$data['wedding-date'] = $_POST['wedding-date'];
$data['email'] = $_POST['email'];
$data['code'] = str_replace(array('/', '-', ' '), '', $_POST['wedding-date']).strtoupper(substr($data['groom-name'], 0, 1)).urlencode('&').strtoupper(substr($data['bride-name'], 0, 1));

// Data array (Should match with data above's order).
$placeholders = array('{groom-name}', '{bride-name}', '{wedding-date}', '{email}', '{code}');

// Get the couples-template.php as a string.
$template = file_get_contents($template_path.$template_file);

// Fills the template.
$new_file = str_replace($placeholders, $data, $template);

// Generates couple's URL and makes it frendly and lowercase.
$couples_url = str_replace(' ', '', strtolower($data['groom-name'].'-'.$data['bride-name'].'.php'));

// Save file into couples directory.
$fp = fopen($couples_path.$couples_url, 'w');
fwrite($fp, $new_file);
fclose($fp);

// Set the variables to pass them to success page.
$_SESSION['couples_url'] = $couples_url;
// If working in root directory.
$_SESSION['couples_path'] = str_replace('.', '', $couples_path);
// If working in a sub directory.
//$_SESSION['couples_path'] = substr_replace($base_path, '', -1).str_replace('.', '',$couples_path);

header('Location: success.php');

?>

Hope this file can help and work as reference to start and boost your project.

This is untested, but I believe the syntax should work for a lambda query. As you join more tables with this syntax you have to drill further down into the new objects to reach the values you want to manipulate.

var fullEntries = dbContext.tbl_EntryPoint
    .Join(
        dbContext.tbl_Entry,
        entryPoint => entryPoint.EID,
        entry => entry.EID,
        (entryPoint, entry) => new { entryPoint, entry }
    )
    .Join(
        dbContext.tbl_Title,
        combinedEntry => combinedEntry.entry.TID,
        title => title.TID,
        (combinedEntry, title) => new 
        {
            UID = combinedEntry.entry.OwnerUID,
            TID = combinedEntry.entry.TID,
            EID = combinedEntry.entryPoint.EID,
            Title = title.Title
        }
    )
    .Where(fullEntry => fullEntry.UID == user.UID)
    .Take(10);

Building on this comment I wrote a one-liner to hit the Github Markdown API using curl and jq.

Paste this bash function onto the command line or into your ~/.bash_profile:

mdsee(){ 
    HTMLFILE="$(mktemp -u).html"
    cat "$1" | \
      jq --slurp --raw-input '{"text": "\(.)", "mode": "markdown"}' | \
      curl -s --data @- https://api.github.com/markdown > "$HTMLFILE"
    echo $HTMLFILE
    open "$HTMLFILE"
}

And then to see the rendered HTML in-browser run:

mdsee readme.md

Replace open "$HTMLFILE" with lynx "$HTMLFILE" if you need a pure terminal solution.

maven-compiler-plugin it's already present in plugins hierarchy dependency in pom.xml. Check in Effective POM.

For short you can use properties like this:

NodeJS supports http.request as a standard module: http://nodejs.org/docs/v0.4.11/api/http.html#http.request

var http = require('http');

var options = {
  host: 'example.com',
  port: 80,
  path: '/foo.html'
};

http.get(options, function(resp){
  resp.on('data', function(chunk){
    //do something with chunk
  });
}).on("error", function(e){
  console.log("Got error: " + e.message);
});

    <script type="text/javascript">
        $(window).on('load',function(){
            setTimeout(function(){ alert(" //show popup"); }, 5000); 
        });
    </script>

def querySet_to_list(qs):
    """

def get_answer_by_something(request):
    ss = Answer.objects.filter(something).values()
    querySet_to_list(ss) # python list return.(json-able)

this code convert django queryset to python list

when you use the svn:// URI it uses port 3690 and probably won't use http proxy

If you are using Angular CLI: 7.3.3 What I did is, On my assets folder I put my fake json data then on my services I just did this.

const API_URL = './assets/data/db.json';

getAllPassengers(): Observable<PassengersInt[]> {
    return this.http.get<PassengersInt[]>(API_URL);
  }

I understand your problem boils down to how to call a SOAP (JAX-WS) web service from Java and get its returning object. In that case, you have two possible approaches:

1. Generate the Java classes through wsimport and use them; or
2. Create a SOAP client that:
   1. Serializes the service's parameters to XML;
   2. Calls the web method through HTTP manipulation; and
   3. Parse the returning XML response back into an object.

About the first approach (using wsimport):

I see you already have the services' (entities or other) business classes, and it's a fact that the wsimport generates a whole new set of classes (that are somehow duplicates of the classes you already have).

I'm afraid, though, in this scenario, you can only either:

• Adapt (edit) the wsimport generated code to make it use your business classes (this is difficult and somehow not worth it - bear in mind everytime the WSDL changes, you'll have to regenerate and readapt the code); or
• Give up and use the wsimport generated classes. (In this solution, you business code could "use" the generated classes as a service from another architectural layer.)

About the second approach (create your custom SOAP client):

In order to implement the second approach, you'll have to:

1. Make the call:
   • Use the SAAJ (SOAP with Attachments API for Java) framework (see below, it's shipped with Java SE 1.6 or above) to make the calls; or
   • You can also do it through java.net.HttpUrlconnection (and some java.io handling).
2. Turn the objects into and back from XML:
   • Use an OXM (Object to XML Mapping) framework such as JAXB to serialize/deserialize the XML from/into objects
   • Or, if you must, manually create/parse the XML (this can be the best solution if the received object is only a little bit differente from the sent one).

Creating a SOAP client using classic java.net.HttpUrlConnection is not that hard (but not that simple either), and you can find in this link a very good starting code.

I recommend you use the SAAJ framework:

SOAP with Attachments API for Java (SAAJ) is mainly used for dealing directly with SOAP Request/Response messages which happens behind the scenes in any Web Service API. It allows the developers to directly send and receive soap messages instead of using JAX-WS.

See below a working example (run it!) of a SOAP web service call using SAAJ. It calls this web service.

import javax.xml.soap.*;

public class SOAPClientSAAJ {

    // SAAJ - SOAP Client Testing
    public static void main(String args[]) {
        /*

             https://www.w3schools.com/xml/tempconvert.asmx?op=CelsiusToFahrenheit


            To call other WS, change the parameters below, which are:
             - the SOAP Endpoint URL (that is, where the service is responding from)
             - the SOAP Action

            Also change the contents of the method createSoapEnvelope() in this class. It constructs
             the inner part of the SOAP envelope that is actually sent.
         */
        String soapEndpointUrl = "https://www.w3schools.com/xml/tempconvert.asmx";

About using JAXB for serializing/deserializing, it is very easy to find information about it. You can start here: http://www.mkyong.com/java/jaxb-hello-world-example/.

here is my implementation

public static byte[] intToByteArray(int a) {
    return BigInteger.valueOf(a).toByteArray();
}

public static int byteArrayToInt(byte[] b) {
    return new BigInteger(b).intValue();
}

I tried the options in the existing answers, mainly the one marked correct which did not work in my scenario. However, what did work was using phpMyAdmin. Select the database and then select the table, from the bottom drop down menu select "Repair table".

• Server type: MySQL
• Server version: 5.7.23 - MySQL Community Server (GPL)
• phpMyAdmin: Version information: 4.7.7

There are some good answers already with explanations of why the mixture of the non-static Context method getText() can't be used with your static final String.

A good question to ask is: why do you want to do this? You are attempting to load a String from your strings resource, and populate its value into a public static field. I assume that this is so that some of your other classes can access it? If so, there is no need to do this. Instead pass a Context into your other classes and call context.getText(R.string.TTT) from within them.

public class NonActivity {

    public static void doStuff(Context context) {
        String TTT = context.getText(R.string.TTT);
        ...
    }
}

And to call this from your Activity:

NonActivity.doStuff(this);

This will allow you to access your String resource without needing to use a public static field.

if you installed its this way(if you not, installing this way):

pip install beautifulsoup4

and if you used its this code(if you not, use this code):

from bs4 import BeautifulSoup

if you using windows system, check it if there are module, might saved different path its module

Since the .Rows result is marked as consisting of rows, you can "For Each" it to deal with each row individually, like this:

Function Attendance(rng As Range) As Long
Attendance = 0
For Each rRow In rng.Rows
    If WorksheetFunction.Sum(rRow) > 0 Then
        Attendance = Attendance + 1
    End If
Next
End Function

I use this to check attendance in any of a few categories (different columns) for a list of people (different rows).

(And of course you could use .Columns to do a "For Each" over the columns in the range.)

I've used Crypkey in the past. It's one of many available.

You can only protect software up to a point with any licensing scheme.

.hide() stores the previous display property just before setting it to none, so if it wasn't the standard display property for the element you're a bit safer, .show() will use that stored property as what to go back to. So...it does some extra work, but unless you're doing tons of elements, the speed difference should be negligible.

One nice way (without adding a fake .js extension which is for code not for data and configs) is to use json-loader module. If you have used create-react-app to scaffold your project, the module is already included, you just need to import your json:

import Profile from './components/profile';

This answer explains more.

This will not work:

wget -q -S -O - google.com 1>wget.txt 2>&1

since redirects are evaluated right to left, this sends html to wget.txt and the header to STDOUT:

wget -q -S -O - google.com 2>&1 1>wget.txt

Git offers a range of difftools pre-configured "out-of-the-box" (kdiff3, kompare, tkdiff, meld, xxdiff, emerge, vimdiff, gvimdiff, ecmerge, diffuse, opendiff, p4merge and araxis), and also allows you to specify your own. To use one of the pre-configured difftools (for example, "vimdiff"), you add the following lines to your ~/.gitconfig:

[diff]
    tool = vimdiff

Now, you will be able to run "git difftool" and use your tool of choice.

Specifying your own difftool, on the other hand, takes a little bit more work, see How do I view 'git diff' output with my preferred diff tool/ viewer?

I tried installing the module locally with version and it worked!!

npm install request@^2.*

Thanks.

Since .NET Framework version 3.0, it is possible to use the Keyboard.IsKeyDown method from the new System.Windows.Input namespace. For instance:

if (((Keyboard.IsKeyDown(Key.LeftCtrl) || Keyboard.IsKeyDown(Key.RightCtrl)) && Keyboard.IsKeyDown(Key.F))
{
    // CTRL + F is currently pressed
}

Even though it's part of WPF, that method works fine for WinForm applications (provided that you add references to PresentationCore.dll and WindowsBase.dll). Unfortunately, however, the 3.0 and 3.5 versions of the Keyboard.IsKeyDown method did not work for WinForm applications. Therefore, if you do want to use it in a WinForm application, you'll need to be targeting .NET Framework 4.0 or later in order for it to work.

By MSDN

The .NET Framework includes the following three predefined IFormatProvider implementations to provide culture-specific information that is used in formatting or parsing numeric and date and time values:

1. The NumberFormatInfo class, which provides information that is used to format numbers, such as the currency, thousands separator, and decimal separator symbols for a particular culture. For information about the predefined format strings recognized by a NumberFormatInfo object and used in numeric formatting operations, see Standard Numeric Format Strings and Custom Numeric Format Strings.
2. The DateTimeFormatInfo class, which provides information that is used to format dates and times, such as the date and time separator symbols for a particular culture or the order and format of a date's year, month, and day components. For information about the predefined format strings recognized by a DateTimeFormatInfo object and used in numeric formatting operations, see Standard Date and Time Format Strings and Custom Date and Time Format Strings.
3. The CultureInfo class, which represents a particular culture. Its GetFormat method returns a culture-specific NumberFormatInfo or DateTimeFormatInfo object, depending on whether the CultureInfo object is used in a formatting or parsing operation that involves numbers or dates and times.

The .NET Framework also supports custom formatting. This typically involves the creation of a formatting class that implements both IFormatProvider and ICustomFormatter. An instance of this class is then passed as a parameter to a method that performs a custom formatting operation, such as String.Format(IFormatProvider, String, Object[]).

okay one other solution that I thought of just for the fun of it would be to turn your decimal into a string and then cut the string into 2 strings, one containing the point and the decimals and the other containing the Int to the left of the point. after that you limit the String of the point and decimals to 3 chars, one for the decimal point and the others for the decimals. then just recombine.

double shippingCost = ((nCartons * 1.44) + (lbs + 1) * 0.96) + 3.0;
String ShippingCost = (String) shippingCost;
String decimalCost = ShippingCost.subString(indexOf('.'),ShippingCost.Length());
ShippingCost = ShippingCost.subString(0,indexOf('.'));
ShippingCost = ShippingCost + decimalCost;

There! Simple, right?

No need to explode anything:

$str_time = "23:12:95";

$str_time = preg_replace("/^([\d]{1,2})\:([\d]{2})$/", "00:$1:$2", $str_time);

sscanf($str_time, "%d:%d:%d", $hours, $minutes, $seconds);

$time_seconds = $hours * 3600 + $minutes * 60 + $seconds;

And if you don't want to use regular expressions:

$str_time = "2:50";

sscanf($str_time, "%d:%d:%d", $hours, $minutes, $seconds);

$time_seconds = isset($seconds) ? $hours * 3600 + $minutes * 60 + $seconds : $hours * 60 + $minutes;

Another way to do this is to tell Mongoose that all you need is a plain JavaScript version of the returned doc by using lean() in the query chain. That way Mongoose skips the step of creating the full model instance and you directly get a doc you can modify:

MyModel.findOne().lean().exec(function(err, doc) {
    doc.addedProperty = 'foobar';
    res.json(doc);
});

Here's how I find valid 10-digit US phone numbers. At this point I'm assuming the user wants my content so the numbers themselves are trusted. I'm using in an app that ultimately sends an SMS message so I just want the raw numbers no matter what. Formatting can always be added later

//eliminate every char except 0-9
$justNums = preg_replace("/[^0-9]/", '', $string);

//eliminate leading 1 if its there
if (strlen($justNums) == 11) $justNums = preg_replace("/^1/", '',$justNums);

//if we have 10 digits left, it's probably valid.
if (strlen($justNums) == 10) $isPhoneNum = true;

Edit: I ended up having to port this to Java, if anyone's interested. It runs on every keystroke so I tried to keep it fairly light:

boolean isPhoneNum = false;
if (str.length() >= 10 && str.length() <= 14 ) { 
  //14: (###) ###-####
  //eliminate every char except 0-9
  str = str.replaceAll("[^0-9]", "");

  //remove leading 1 if it's there
  if (str.length() == 11) str = str.replaceAll("^1", "");

  isPhoneNum = str.length() == 10;
}
Log.d("ISPHONENUM", String.valueOf(isPhoneNum));

we have 2 form in this project. in main form change

private void button1_Click(object sender, EventArgs e) { // work }

to

public void button1_Click(object sender, EventArgs e) { // work }

and in other form, when we need above function

        private void button2_Click(object sender, EventArgs e)
    {
        main_page() obj = new main_page();
        obj.button2_Click(sender, e);
    }

something like

  position:relative;
  top:-5px;

just on the inline element itself works for me. Have to play with the top to get it centered vertically...

How about a shorthand notation?

{overflow: auto hidden;}

The following line will work: document.location.ancestorOrigins[0] this one returns the ancestor domain name.

As per the recent changes you can use: (1) Ctrl/Shift/(+) for Zoom-in (2) Ctrl/Shift/(-) for Zoom-out

Use each: 'i' is the postion in the array, obj is the DOM object that you are iterating (can be accessed through the jQuery wrapper $(this) as well).

$('.testimonial').each(function(i, obj) {
    //test
});

Check the api reference for more information.

There are a number of ways to go about this. One way would be to enter the date 8/1/2013 manually in the first cell (say A1 for example's sake) and then in B1 type the following formula (and then drag it across):

=DATE(YEAR(A1),MONTH(A1)+1,1)

Since you only want to see month and year, you can format accordingly using the different custom date formats available.

The format you're looking for is YY-Mmm.

Note that a similar issue can bite you if you use os.path.join() to include an extension that already includes a dot, which is what happens automatically when you use os.path.splitext(). In this example:

components = os.path.splitext(filename)
prefix = components[0]
extension = components[1]
return os.path.join("avatars", instance.username, prefix, extension)

Even though extension might be .jpg you end up with a folder named "foobar" rather than a file called "foobar.jpg". To prevent this you need to append the extension separately:

return os.path.join("avatars", instance.username, prefix) + extension

Check that all your bundle resources are copied in build phase.

Precedence differs between && and and (&& has higher precedence than and), something that causes confusion when combined with a ternary operator. For instance,

$predA && $predB ? "foo" : "bar"

will return a string whereas

$predA and $predB ? "foo" : "bar"

will return a boolean.

Enable and Disable functionality is same for most of the widgets.

Ex, button , switch, checkbox etc.

Just set the onPressed property as shown below

onPressed : null returns Disabled widget

onPressed : (){} or onPressed : _functionName returns Enabled widget

Just to throw in another example, the generic version of Class (Class<T>) allows one to write generic functions such as the one below.

public static <T extends Enum<T>>Optional<T> optionalFromString(
        @NotNull Class<T> clazz,
        String name
) {
    return Optional<T> opt = Optional.ofNullable(name)
            .map(String::trim)
            .filter(StringUtils::isNotBlank)
            .map(String::toUpperCase)
            .flatMap(n -> {
                try {
                    return Optional.of(Enum.valueOf(clazz, n));
                } catch (Exception e) {
                    return Optional.empty();
                }
            });
}

The trunk is the main line of development in a SVN repository.

A branch is a side-line of development created to make larger, experimental or disrupting work without annoying users of the trunk version. Also, branches can be used to create development lines for multiple versions of the same product, like having a place to backport bugfixes into a stable release.

Finally, tags are markers to highlight notable revisions in the history of the repository, usually things like "this was released as 1.0".

See the HTML version of "Version Control with Subversion", especially Chapter 4: Branching and Merging or buy it in paper (e.g. from amazon) for an in-depth discussion of the technical details.

As others (e.g. Peter Neubauer below) the underlying implementation as /tags /branches and /trunk directories is only conventional and not in any way enforced by the tools. Violating these conventions leads to confusion all around, as this breaks habits and expectations of others accessing the repository. Special care must be taken to avoid committing new changes into tags, which should be frozen.

I use TortoiseSVN but no Visual Studio integration. I keep the "Check for modifications" dialog open on the second monitor the whole time, so I can track which files I have touched. But see the "Best SVN Tools" question, for more recommendations.

stage.setOnCloseRequest(new EventHandler<WindowEvent>() {
    public void handle(WindowEvent we) {                        
        Platform.setImplicitExit(false);
        stage.close();
    }
});

It is equivalent to hide. So when you are going to open it next time, you just check if the stage object is exited or not. If it is exited, you just show() i.e. (stage.show()) call. Otherwise, you have to start the stage.

Try this

 String str="10,692,467,440,017.120".replaceAll(",","");
 BigDecimal bd=new BigDecimal(str);

You don't show the code for display_data, but here's what you need to do:

print "$%0.02f" %amount

This is a format specifier for the variable amount.

Since this is beginner topic, I won't get into floating point rounding error, but it's good to be aware that it exists.

use the new line character of a javascript instead of '\n'.. eg: "Hello\nWorld" use "Hello\x0AWorld" It works great!!

Add this code in web.config under the <configuration> tag as shown in image below. Your error should then be gone.

<configuration>
  <appSettings>
    <add key="owin:AutomaticAppStartup" value="false" />
  </appSettings>
  ...
</configuration>

if you are still interested, this function removes spaces from the beginning of the string, and I just had it working in my code:

void removeSpaces(char *str1)  
{
    char *str2; 
    str2=str1;  
    while (*str2==' ') str2++;  
    if (str2!=str1) memmove(str1,str2,strlen(str2)+1);  
}

Using \n in sed is non-portable. The portable way to do what you want with sed is:

sed 's/:/\
/g' ~/Desktop/myfile.txt

but in reality this isn't a job for sed anyway, it's the job tr was created to do:

tr ':' '
' < ~/Desktop/myfile.txt

Technically not an answer to this, but a good use of the accepted answer (https://stackoverflow.com/a/20928975/82028) to create next and prev buttons for the tabs on jQuery ACF fields:

$('.next').click(function () {
    $('#primary li.active').next().find('.acf-tab-button')[0].click();
});

$('.prev').click(function () {
    $('#primary li.active').prev().find('.acf-tab-button')[0].click();
});

A tip to all people that use flat-red, flat-green plugin, because of this plugin the answers above wont work!

In that case, use onchange="do_your_stuff();" on the label, for example: Your checkbox here

The reason why it doesn't work is that this Jquery creates a lot of objects around the real checkbox, so you can't see if it's changed or not.

But if someone click straight on checkbox, won't work :'(

On your DBA account, give USERB the right to create a procedure using grant grant create any procedure to USERB

The procedure will look

CREATE OR REPLACE PROCEDURE USERB.USERB_PROCEDURE
--Must add the line below
AUTHID CURRENT_USER AS
  BEGIN
  --DO SOMETHING HERE
  END
END

GRANT EXECUTE ON USERB.USERB_PROCEDURE TO USERA

I know this is a very old question but I am hoping I could chip it a bit.

If your %file% is an input parameter, you may use %~zN, where N is the number of the parameter.

E.g. a test.bat containing

@echo %~z1

Will display the size of the first parameter, so if you use "test myFile.txt" it will display the size of the corresponding file.

For US Address Parsing,

I prefer using usaddress package that is available in pip for usaddress only

python3 -m pip install usaddress

Documentation
PyPi

This worked well for me for US address.

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

# address_parser.py
import sys
from usaddress import tag
from json import dumps, loads

if __name__ == '__main__':
    tag_mapping = {
        'Recipient': 'recipient',

        'AddressNumberPrefix': 'addressStreet',
        'AddressNumberSuffix': 'addressStreet',

    }
    try:
        address, _ = tag(' '.join(sys.argv[1:]), tag_mapping=tag_mapping)
    except:
        with open('failed_address.txt', 'a') as fp:
            fp.write(sys.argv[1] + '\n')
        print(dumps({}))
    else:
        print(dumps(dict(address)))

Running the address_parser.py

 python3 address_parser.py 9757 East Arcadia Ave. Saugus MA 01906

Sets require their items to be hashable. Out of types predefined by Python only the immutable ones, such as strings, numbers, and tuples, are hashable. Mutable types, such as lists and dicts, are not hashable because a change of their contents would change the hash and break the lookup code.

Since you're sorting the list anyway, just place the duplicate removal after the list is already sorted. This is easy to implement, doesn't increase algorithmic complexity of the operation, and doesn't require changing sublists to tuples:

def uniq(lst):
    last = object()
    for item in lst:
        if item == last:
            continue
        yield item
        last = item

def sort_and_deduplicate(l):
    return list(uniq(sorted(l, reverse=True)))

Sometimes, a textual representation might also help; with this query on the system catalog views, you can get a list of all FK relationships and how the link two tables (and what columns they operate on).

SELECT
    fk.name 'FK Name',
    tp.name 'Parent table',
    cp.name, cp.column_id,
    tr.name 'Refrenced table',
    cr.name, cr.column_id
FROM 
    sys.foreign_keys fk
INNER JOIN 
    sys.tables tp ON fk.parent_object_id = tp.object_id
INNER JOIN 
    sys.tables tr ON fk.referenced_object_id = tr.object_id
INNER JOIN 
    sys.foreign_key_columns fkc ON fkc.constraint_object_id = fk.object_id
INNER JOIN 
    sys.columns cp ON fkc.parent_column_id = cp.column_id AND fkc.parent_object_id = cp.object_id
INNER JOIN 
    sys.columns cr ON fkc.referenced_column_id = cr.column_id AND fkc.referenced_object_id = cr.object_id
ORDER BY
    tp.name, cp.column_id

Dump this into Excel, and you can slice and dice - based on the parent table, the referenced table or anything else.

I find visual guides helpful - but sometimes, textual documentation is just as good (or even better) - just my 2 cents.....

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);

$parts = explode("\r\n\r\nHTTP/", $response);
$parts = (count($parts) > 1 ? 'HTTP/' : '').array_pop($parts);
list($headers, $body) = explode("\r\n\r\n", $parts, 2);

Works with HTTP/1.1 100 Continue before other headers.

If you need work with buggy servers which sends only LF instead of CRLF as line breaks you can use preg_split as follows:

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);

$parts = preg_split("@\r?\n\r?\nHTTP/@u", $response);
$parts = (count($parts) > 1 ? 'HTTP/' : '').array_pop($parts);
list($headers, $body) = preg_split("@\r?\n\r?\n@u", $parts, 2);

I solved this problem using Bootstrap 4 Emdeds Utilities

https://getbootstrap.com/docs/4.3/utilities/embed

In this case you just need to add you image to a div.embbed-responsive like this:

<div class="card">
  <div class="embed-responsive embed-responsive-16by9">
     <img alt="Card image cap" class="card-img-top embed-responsive-item" src="img/butterPecan.jpg" />
  </div>
  <div class="card-block">
    <h4 class="card-title">Butter Pecan</h4>
    <p class="card-text">Roasted pecans, butter and vanilla come together to make this wonderful ice cream</p>
  </div>
</div>

All images will fit the ratio specified by modifier classes:

• .embed-responsive-21by9
• .embed-responsive-16by9
• .embed-responsive-4by3
• .embed-responsive-1by1

Aditionally this css enables zoom instead of image stretching

.embed-responsive .card-img-top {
    object-fit: cover;
}

The question has already been awarded, but there are additional details not yet described that need to be checked.

I too was having this behavior, where project B was referenced in project A, but the namespace of project B was not recognized in project A. After some digging, I found my path was too long. By reducing the path of the projects (both A and B) the references became visible and available.

I tested this theory by creating project C at a much lesser path depth. I referenced project C in project A. The references worked correctly as expected. I then removed project C from the solution, merely moved project C to a deep path, the same as project B, and added project C back to the solution, and tried to compile. I then had no visibility to project C objects any longer.

Both certificates should exist prior to the connection. They're usually created by Certification Authorities (not necessarily the same). (There are alternative cases where verification can be done differently, but some verification will need to be made.)

The server certificate should be created by a CA that the client trusts (and following the naming conventions defined in RFC 6125).

The client certificate should be created by a CA that the server trusts.

It's up to each party to choose what it trusts.

There are online CA tools that will allow you to apply for a certificate within your browser and get it installed there once the CA has issued it. They need not be on the server that requests client-certificate authentication.

The certificate distribution and trust management is the role of the Public Key Infrastructure (PKI), implemented via the CAs. The SSL/TLS client and servers and then merely users of that PKI.

When the client connects to a server that requests client-certificate authentication, the server sends a list of CAs it's willing to accept as part of the client-certificate request. The client is then able to send its client certificate, if it wishes to and a suitable one is available.

The main advantages of client-certificate authentication are:

• The private information (the private key) is never sent to the server. The client doesn't let its secret out at all during the authentication.
• A server that doesn't know a user with that certificate can still authenticate that user, provided it trusts the CA that issued the certificate (and that the certificate is valid). This is very similar to the way passports are used: you may have never met a person showing you a passport, but because you trust the issuing authority, you're able to link the identity to the person.

You may be interested in Advantages of client certificates for client authentication? (on Security.SE).

Is there something that prevents you from merging all revisions on trunk since the last merge?

svn merge -rLastRevisionMergedFromTrunkToBranch:HEAD url/of/trunk path/to/branch/wc

should work just fine. At least if you want to merge all changes on trunk to your branch.

Easier method is window.location.href = "http://example.com/new_url";

But what if you want to check if username and password whether empty or not using JavaScript and send it to the php to check whether user in the database. You can do this easily following this code.

html form -

<form name="myForm" onsubmit="return validateForm()" method="POST" action="login.php" >         
    <input type="text" name="username" id="username" />
    <input type="password" name="password" id="password" />
    <input type="submit" name="submitBt"value="LogIn" />
</form>

javascript validation-

function validateForm(){
    var uname = document.forms["myForm"]["username"].value;
    var pass = document.forms["myForm"]["password"].value;

    if((!isEmpty(uname, "Log In")) && (!isEmpty(pass, "Password"))){

        return true;
    }else{
        return false;
    }
}

function isEmpty(elemValue, field){
    if((elemValue == "") || (elemValue == null)){
        alert("you can not have "+field+" field empty");
        return true;
    }else{
        return false;
    }
}

check if user in the database using php

<?php
    $con = mysqli_connect("localhost","root","1234","users");

    if(mysqli_connect_errno()){
        echo "Couldn't connect ".mysqli_connect_error();
    }else{
        //echo "connection successful <br />";
    }

    $uname_tb = $_POST['username'];
    $pass_tb = $_POST['password'];

    $query ="SELECT * FROM user";
    $result = mysqli_query($con,$query);

    while($row = mysqli_fetch_array($result)){
        if(($row['username'] == $uname_tb) && ($row['password'] == $pass_tb)){
            echo "Login Successful";
            header('Location: dashbord.php');
            exit();
        }else{
            echo "You are not in our database".mysqli_connect_error();
        }
    }
    mysqli_close($con);
?>

<?php
session_start();
  mysql_connect('localhost','root','');
    mysql_select_db('database name goes here');
    $error_msg=NULL;
    //log out code
    if(isset($_REQUEST['logout'])){
                unset($_SESSION['user']);
                unset($_SESSION['username']);
                unset($_SESSION['id']);
                unset($_SESSION['role']);
        session_destroy();
    }
    //

    if(!empty($_POST['submit'])){
        if(empty($_POST['username']))
            $error_msg='please enter username';
        if(empty($_POST['password']))
            $error_msg='please enter password';
        if(empty($error_msg)){
            $sql="SELECT*FROM users WHERE username='%s' AND password='%s'";
            $sql=sprintf($sql,$_POST['username'],md5($_POST['password']));
            $records=mysql_query($sql) or die(mysql_error());

            if($record_new=mysql_fetch_array($records)){

                $_SESSION['user']=$record_new;
                $_SESSION['id']=$record_new['id'];
                $_SESSION['username']=$record_new['username'];
                $_SESSION['role']=$record_new['role'];
                header('location:index.php');
                $error_msg='welcome';
                exit();
            }else{
                $error_msg='invalid details';
            }
        }       
    }

?>

// replace the location with whatever page u want the user to visit when he/she log in

I know this question is old now, but after doing a ton of research on various solutions to this problem, I think I may have come up with a better solution.

UPDATE 1: Since posting this answer, I have added all of this code to a simple service that I have posted to GitHub. The repo is located here. Feel free to check it out for more info.

UPDATE 2: This answer is great if all you need is a lightweight solution for pulling in stylesheets for your routes. If you want a more complete solution for managing on-demand stylesheets throughout your application, you may want to checkout Door3's AngularCSS project. It provides much more fine-grained functionality.

In case anyone in the future is interested, here's what I came up with:

1. Create a custom directive for the <head> element:

app.directive('head', ['$rootScope','$compile',
    function($rootScope, $compile){
        return {
            restrict: 'E',
            link: function(scope, elem){
                var html = '<link rel="stylesheet" ng-repeat="(routeCtrl, cssUrl) in routeStyles" ng-href="{{cssUrl}}" />';
                elem.append($compile(html)(scope));
                scope.routeStyles = {};
                $rootScope.$on('$routeChangeStart', function (e, next, current) {
                    if(current && current.$$route && current.$$route.css){
                        if(!angular.isArray(current.$$route.css)){
                            current.$$route.css = [current.$$route.css];
                        }
                        angular.forEach(current.$$route.css, function(sheet){
                            delete scope.routeStyles[sheet];
                        });
                    }
                    if(next && next.$$route && next.$$route.css){
                        if(!angular.isArray(next.$$route.css)){
                            next.$$route.css = [next.$$route.css];
                        }
                        angular.forEach(next.$$route.css, function(sheet){
                            scope.routeStyles[sheet] = sheet;
                        });
                    }
                });
            }
        };
    }
]);

This directive does the following things:

1. It compiles (using $compile) an html string that creates a set of <link /> tags for every item in the scope.routeStyles object using ng-repeat and ng-href.
2. It appends that compiled set of <link /> elements to the <head> tag.
3. It then uses the $rootScope to listen for '$routeChangeStart' events. For every '$routeChangeStart' event, it grabs the "current" $$route object (the route that the user is about to leave) and removes its partial-specific css file(s) from the <head> tag. It also grabs the "next" $$route object (the route that the user is about to go to) and adds any of its partial-specific css file(s) to the <head> tag.
4. And the ng-repeat part of the compiled <link /> tag handles all of the adding and removing of the page-specific stylesheets based on what gets added to or removed from the scope.routeStyles object.

Note: this requires that your ng-app attribute is on the <html> element, not on <body> or anything inside of <html>.

2. Specify which stylesheets belong to which routes using the $routeProvider:

app.config(['$routeProvider', function($routeProvider){
    $routeProvider
        .when('/some/route/1', {
            templateUrl: 'partials/partial1.html', 
            controller: 'Partial1Ctrl',
            css: 'css/partial1.css'
        })
        .when('/some/route/2', {
            templateUrl: 'partials/partial2.html',
            controller: 'Partial2Ctrl'
        })
        .when('/some/route/3', {
            templateUrl: 'partials/partial3.html',
            controller: 'Partial3Ctrl',
            css: ['css/partial3_1.css','css/partial3_2.css']
        })
}]);

This config adds a custom css property to the object that is used to setup each page's route. That object gets passed to each '$routeChangeStart' event as .$$route. So when listening to the '$routeChangeStart' event, we can grab the css property that we specified and append/remove those <link /> tags as needed. Note that specifying a css property on the route is completely optional, as it was omitted from the '/some/route/2' example. If the route doesn't have a css property, the <head> directive will simply do nothing for that route. Note also that you can even have multiple page-specific stylesheets per route, as in the '/some/route/3' example above, where the css property is an array of relative paths to the stylesheets needed for that route.

3. You're done Those two things setup everything that was needed and it does it, in my opinion, with the cleanest code possible.

Hope that helps someone else who might be struggling with this issue as much as I was.

Originally from this blog post. We can achieve if else by using below code

<xsl:choose>
    <xsl:when test="something to test">

    </xsl:when>
    <xsl:otherwise>

    </xsl:otherwise>
</xsl:choose>

So here is what I did

<h3>System</h3>
    <xsl:choose>
        <xsl:when test="autoIncludeSystem/autoincludesystem_info/@mdate"> <!-- if attribute exists-->
            <p>

                            <th>File Size</th>
                            <th>Date</th>
                            <th>Time</th>
                            <th>AM/PM</th>
                        </tr>
                        <xsl:for-each select="autoIncludeSystem/autoincludesystem_info">
                            <tr>

                            </tr>
                        </xsl:for-each>
                    </tbody>
                </table>

        </xsl:otherwise>
    </xsl:choose>

My Output

You should be using SqlConnection.State

e.g,

using System.Data;

if (myConnection != null && myConnection.State == ConnectionState.Closed)
{
   // do something
   // ...
}

Many changes you can make very easily and visually in the table editor in SQL Server Management Studio actually require SSMS to drop the table in the background and re-create it from scratch. Even simple things like reordering the columns cannot be expressed in standard SQL DDL statement - all SSMS can do is drop and recreate the table.

This operation can be a) very time consuming on a large table, or b) might even fail for various reasons (like FK constraints and stuff). Therefore, SSMS in SQL Server 2008 introduced that new option the other answers have already identified.

It might seem counter-intuitive at first to prevent such changes - and it's certainly a nuisance on a dev server. But on a production server, this option and its default value of preventing such changes becomes a potential life-saver!

For python 2.7 another trick is:

arr = [1,2,3]
for num in arr:
  print num,
# will print 1 2 3

For me, this worked:

1. Login as the owner of the process (even root is denied permission)

   ~$ su - process_owner
   

2. Tail the file descriptor as mentioned in many other answers.

   ~$ tail -f /proc/<process-id>/fd/1 # (0: stdin, 1: stdout, 2: stderr)
   

If you have WL server installed, pick it up from under
\Oracle\Middleware\wlserver_10.3\server\lib\mysql-connector-java-commercial-5.1.17-bin.jar

Collections.singletonList(object)

the list created by this method is immutable.

Pretty sad, eh? The way I usually do it is build up a container of iterators instead of deleting during traversal. Then loop through the container and use map.erase()

std::map<K,V> map;
std::list< std::map<K,V>::iterator > iteratorList;

for(auto i : map ){
    if ( needs_removing(i)){
        iteratorList.push_back(i);
    }
}
for(auto i : iteratorList){
    map.erase(*i)
}

Put

input('Press ENTER to exit') 

at the end to have it stop.

You have to use GROUP BY so you will have multiple records returned,

SELECT  COUNT(*) TotalCount, 
        b.category_id, 
        b.category_name 
FROM    table1 a
        INNER JOIN table2 b
            ON a.category_id = b.category_id 
WHERE   a.colour <> 'red'
GROUP   BY b.category_id, b.category_name

If you don't have the source code and API documentation, the machine code is all there is, you need to disassemble the dll library using something like IDA Pro , another option is use the trial version of PE Explorer.

PE Explorer provides a Disassembler. There is only one way to figure out the parameters: run the disassembler and read the disassembly output. Unfortunately, this task of reverse engineering the interface cannot be automated.

PE Explorer comes bundled with descriptions for 39 various libraries, including the core Windows® operating system libraries (eg. KERNEL32, GDI32, USER32, SHELL32, WSOCK32), key graphics libraries (DDRAW, OPENGL32) and more.

It's to access a member function or member variable of an object through a pointer, as opposed to a regular variable or reference.

For example: with a regular variable or reference, you use the . operator to access member functions or member variables.

std::string s = "abc";
std::cout << s.length() << std::endl;

But if you're working with a pointer, you need to use the -> operator:

std::string* s = new std::string("abc");
std::cout << s->length() << std::endl;

It can also be overloaded to perform a specific function for a certain object type. Smart pointers like shared_ptr and unique_ptr, as well as STL container iterators, overload this operator to mimic native pointer semantics.

For example:

std::map<int, int>::iterator it = mymap.begin(), end = mymap.end();
for (; it != end; ++it)
    std::cout << it->first << std::endl;

.NET core 3.X

no need to create new model and to set in Startup.cs.

Controller Add new package - using Microsoft.Extensions.Configuration;

public class HomeController : Controller
{
    private readonly IConfiguration _mySettings;

    public HomeController (IConfiguration mySettings)
    {
         _mySettings= mySettings;
    }
 
    //ex: you can get value on below function 
    public IEnumerable<string> Get()
    {
        var result = _config.GetValue<string>("AppSettings:Version"); // "One"
        return new string[] { result.ToString() };
    }
}

For my txt file works this way:

let myFileURL = NSBundle.mainBundle().URLForResource("listacomuni", withExtension: "txt")!
let myText = try! String(contentsOfURL: myFileURL, encoding: NSISOLatin1StringEncoding)
print(String(myText))

Before you implement this solution it's important to know that Webkit currently doesn't do this.

Here is the relevant issue on the Chrome issue tracker: http://code.google.com/p/chromium/issues/detail?id=24826

And on the Webkit issue tracker: https://bugs.webkit.org/show_bug.cgi?id=17205

Star it on the Chrome issue tracker if you want to show that it is important to you (I did).

Here is a method I use to both iterate an enum and provide multiple values types from one enum

enum IterateEnum: Int {
    case Zero
    case One
    case Two
    case Three
    case Four
    case Five
    case Six
    case Seven

    //tuple allows multiple values to be derived from the enum case, and
    //since it is using a switch with no default, if a new case is added,
    //a compiler error will be returned if it doesn't have a value tuple set
    var value: (french: String, spanish: String, japanese: String) {
        switch self {
        case .Zero: return (french: "zéro", spanish: "cero", japanese: "nuru")
        case .One: return (french: "un", spanish: "uno", japanese: "ichi")
        case .Two: return (french: "deux", spanish: "dos", japanese: "ni")
        case .Three: return (french: "trois", spanish: "tres", japanese: "san")
        case .Four: return (french: "quatre", spanish: "cuatro", japanese: "shi")
        case .Five: return (french: "cinq", spanish: "cinco", japanese: "go")
        case .Six: return (french: "six", spanish: "seis", japanese: "roku")
        case .Seven: return (french: "sept", spanish: "siete", japanese: "shichi")
        }
    }

    //Used to iterate enum or otherwise access enum case by index order.
    //Iterate by looping until it returns nil
    static func item(index: Int) -> IterateEnum? {
        return IterateEnum.init(rawValue: index)
    }

    static func numberFromSpanish(number: String) -> IterateEnum? {
        return findItem { $0.value.spanish == number }
    }

    //use block to test value property to retrieve the enum case        
    static func findItem(predicate: ((_: IterateEnum) -> Bool)) -> IterateEnum? {

        var enumIndex: Int = -1
        var enumCase: IterateEnum?

        //Iterate until item returns nil
        repeat {
            enumIndex += 1
            enumCase = IterateEnum.item(index: enumIndex)

            if let eCase = enumCase {

                if predicate(eCase) {
                    return eCase
                }
            }
        } while enumCase != nil
        return nil
    }
}

var enumIndex: Int = -1
var enumCase: IterateEnum?

// Iterate until item returns nil
repeat {
    enumIndex += 1
    enumCase = IterateEnum.item(index: enumIndex)
    if let eCase = enumCase {
        print("The number \(eCase) in french: \(eCase.value.french), spanish: \(eCase.value.spanish), japanese: \(eCase.value.japanese)")
    }
} while enumCase != nil

print("Total of \(enumIndex) cases")

let number = IterateEnum.numberFromSpanish(number: "siete")

print("siete in japanese: \((number?.value.japanese ?? "Unknown"))")

This is the output:

The number Zero in french: zéro, spanish: cero, japanese: nuru
The number One in french: un, spanish: uno, japanese: ichi
The number Two in french: deux, spanish: dos, japanese: ni
The number Three in french: trois, spanish: tres, japanese: san
The number Four in french: quatre, spanish: cuatro, japanese: shi
The number Five in french: cinq, spanish: cinco, japanese: go
The number Six in french: six, spanish: seis, japanese: roku
The number Seven in french: sept, spanish: siete, japanese: shichi

Total of 8 cases

siete in japanese: shichi

UPDATE

I recently created a protocol to handle the enumeration. The protocol requires an enum with an Int raw value:

protocol EnumIteration {

    //Used to iterate enum or otherwise access enum case by index order. Iterate by looping until it returns nil

    static func item(index:Int) -> Self?
    static func iterate(item:((index:Int, enumCase:Self)->()), completion:(()->())?) {
    static func findItem(predicate:((enumCase:Self)->Bool)) -> Self?
    static func count() -> Int
}

extension EnumIteration where Self: RawRepresentable, Self.RawValue == Int {

    //Used to iterate enum or otherwise access enum case by index order. Iterate by looping until it returns nil
    static func item(index:Int) -> Self? {
        return Self.init(rawValue: index)
    }

    static func iterate(item:((index:Int, enumCase:Self)->()), completion:(()->())?) {

        var enumIndex:Int = -1
        var enumCase:Self?

        //Iterate until item returns nil
        repeat {
            enumIndex += 1
            enumCase = Self.item(enumIndex)

            if let eCase = enumCase {
                item(index: enumIndex, enumCase: eCase)
            }
        } while enumCase != nil
        completion?()
    }

    static func findItem(predicate:((enumCase:Self)->Bool)) -> Self? {

        var enumIndex:Int = -1
        var enumCase:Self?

        //Iterate until item returns nil
        repeat {
            enumIndex += 1
            enumCase = Self.item(enumIndex)

            if let eCase = enumCase {

                if predicate(enumCase:eCase) {
                    return eCase
                }
            }
        } while enumCase != nil
        return nil
    }

    static func count() -> Int {
        var enumIndex:Int = -1
        var enumCase:Self?

        //Iterate until item returns nil
        repeat {
            enumIndex += 1
            enumCase = Self.item(enumIndex)
        } while enumCase != nil

        //last enumIndex (when enumCase == nil) is equal to the enum count
        return enumIndex
    }
}

I was getting the error A client error (403) occurred when calling the HeadObject operation: Forbidden for my aws cli copy command aws s3 cp s3://bucket/file file. I was using a IAM role which had full S3 access using an Inline Policy.

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "s3:*",
      "Resource": "*"
    }
  ]
}

If I give it the full S3 access from the Managed Policies instead, then the command works. I think this must be a bug from Amazon, because the policies in both cases were exactly the same.

Run a test.

   string coerce:          7.42296099663
   string cast:            8.05654597282
   string fail coerce:     7.14159703255
   string fail cast:       7.87444186211

This was a test that ran each scenario 10,000,000 times. :-)

Co-ercion is 0 + "123"

Casting is (integer)"123"

I think Co-ercion is a tiny bit faster. Oh, and trying 0 + array('123') is a fatal error in PHP. You might want your code to check the type of the supplied value.

My test code is below.

function test_string_coerce($s) {
    return 0 + $s;
}

function test_string_cast($s) {
    return (integer)$s;
}

$iter = 10000000;

print "-- running each text $iter times.\n";

// string co-erce
$string_coerce = new Timer;
$string_coerce->Start();

print "String Coerce test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_coerce('123');
}

$string_coerce->Stop();

// string cast
$string_cast = new Timer;
$string_cast->Start();

print "String Cast test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_cast('123');
}

$string_cast->Stop();

// string co-erce fail.
$string_coerce_fail = new Timer;
$string_coerce_fail->Start();

print "String Coerce fail test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_coerce('hello');
}

$string_coerce_fail->Stop();

// string cast fail
$string_cast_fail = new Timer;
$string_cast_fail->Start();

print "String Cast fail test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_cast('hello');
}

$string_cast_fail->Stop();

// -----------------
print "\n";
print "string coerce:          ".$string_coerce->Elapsed()."\n";
print "string cast:            ".$string_cast->Elapsed()."\n";
print "string fail coerce:     ".$string_coerce_fail->Elapsed()."\n";
print "string fail cast:       ".$string_cast_fail->Elapsed()."\n";


class Timer {
    var $ticking = null;
    var $started_at = false;
    var $elapsed = 0;

    function Timer() {
        $this->ticking = null;
    }

    function Start() {
        $this->ticking = true;
        $this->started_at = microtime(TRUE);
    }

    function Stop() {
        if( $this->ticking )
            $this->elapsed = microtime(TRUE) - $this->started_at;
        $this->ticking = false;
    }

    function Elapsed() {
        switch( $this->ticking ) {

            case null: return "Not Started";
        }
    }
}

A sample code that works for me on Windows:

import requests

with open('pic1.jpg', 'wb') as handle:
        response = requests.get(pic_url, stream=True)

        if not response.ok:
            print response

        for block in response.iter_content(1024):
            if not block:
                break

            handle.write(block)

If your class is non-activity class, and creating an instance of it from the activiy, you can pass an instance of context via constructor of the later as follows:

class YourNonActivityClass{

// variable to hold context
private Context context;

//save the context recievied via constructor in a local variable

public YourNonActivityClass(Context context){
    this.context=context;
}

}

You can create instance of this class from the activity as follows:

new YourNonActivityClass(this);

Two possible situations :

• Your company uses a proxy to connect to the public Maven repository. Then ask someone in your company what the IP address of the proxy is then put it in your settings.xml file

• Your company has its/their own Maven repository/ies (Nexus repository for example). Then ask someone in your company what the Nexus repository is then put it in your pom.xml or in your settings.xml. See Adding maven nexus repo to my pom.xml and https://maven.apache.org/guides/mini/guide-multiple-repositories.html

The PathUtil method will be only working in below oreo and if it is oreo than it is likely to crash because in oreo we will not get the id but the entire path in data.getData() so all u need to do is create a file from uri and get its path from getPath() and split it.below is the working code:-

Uri uri = data.getData(); 
File file = new File(uri.getPath());//create path from uri
final String[] split = file.getPath().split(":");//split the path.
filePath = split[1];//assign it to a string(your choice).

The above code will work in oreo and if it is below oreo than PathUtil will work.Thanks!

String filePath=PathUtil.getPath(context,yourURI);

I was interested in this as well and came across some examples on the Spring Boot site.

   // get with query string parameters e.g. /system/resource?id="rtze1cd2"&person="sam smith" 
// so below the first query parameter id is the variable and name is the variable
// id is shown below as a RequestParam
    @GetMapping("/system/resource")
    // this is for swagger docs
    @ApiOperation(value = "Get the resource identified by id and person")
    ResponseEntity<?> getSomeResourceWithParameters(@RequestParam String id, @RequestParam("person") String name) {

        InterestingResource resource = getMyInterestingResourc(id, name);
        logger.info("Request to get an id of "+id+" with a name of person: "+name);

        return new ResponseEntity<Object>(resource, HttpStatus.OK);
    }

Since wdiff accepts args specifying the string at the beginning and end of both insertions and deletions, you can use ANSI color sequences as those strings:

wdiff -n -w $'\033[30;41m' -x $'\033[0m' -y $'\033[30;42m' -z $'\033[0m' file1 file2

For example, this is the output of comparing two CSV files:

Example from https://www.gnu.org/software/wdiff/manual/html_node/wdiff-Examples.html

begin transaction

// execute SQL code here

rollback transaction

If you've already executed the query and want to roll it back, unfortunately your only real option is to restore a database backup. If you're using Full backups, then you should be able to restore the database to a specific point in time.

The form element has an autocomplete attribute that you can set to off. As of the CSS the !important directive after a property keeps it from being overriden:

background-color: white !important;

Only IE6 doesn't understand it.

If I misunderstood you, there's also the outline property that you could find useful.

To make the query run faster in big tables where not every line needs to be updated, you can also choose to only update rows that will be modified:

UPDATE dbo.xxx
SET Value = REPLACE(Value, '123', '')
WHERE ID <= 4
AND Value LIKE '%123%'

Here is an alternative.

var condition = true;

var props = {
  value: 'foo',
  ...( condition && { disabled: true } )
};

var component = <div { ...props } />;

Or its inline version

var condition = true;

var component = (
  <div
    value="foo"
    { ...( condition && { disabled: true } ) } />
);

Tracing helped me find what the problem was (Thank you Fabian for that suggestion). I found with further testing that I could get the client certificate to work on another server (Windows Server 2012). I was testing this on my development machine (Window 7) so I could debug this process. So by comparing the trace to an IIS Server that worked and one that did not I was able to pinpoint the relevant lines in the trace log. Here is a portion of a log where the client certificate worked. This is the setup right before the send

System.Net Information: 0 : [17444] InitializeSecurityContext(In-Buffers count=2, Out-Buffer length=0, returned code=CredentialsNeeded).
System.Net Information: 0 : [17444] SecureChannel#54718731 - We have user-provided certificates. The server has not specified any issuers, so try all the certificates.
System.Net Information: 0 : [17444] SecureChannel#54718731 - Selected certificate:

Here is what the trace log looked like on the machine where the client certificate failed.

System.Net Information: 0 : [19616] InitializeSecurityContext(In-Buffers count=2, Out-Buffer length=0, returned code=CredentialsNeeded).
System.Net Information: 0 : [19616] SecureChannel#54718731 - We have user-provided certificates. The server has specified 137 issuer(s). Looking for certificates that match any of the issuers.
System.Net Information: 0 : [19616] SecureChannel#54718731 - Left with 0 client certificates to choose from.
System.Net Information: 0 : [19616] Using the cached credential handle.

Focusing on the line that indicated the server specified 137 issuers I found this Q&A that seemed similar to my issue. The solution for me was not the one marked as an answer since my certificate was in the trusted root. The answer is the one under it where you update the registry. I just added the value to the registry key.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL

Value name: SendTrustedIssuerList Value type: REG_DWORD Value data: 0 (False)

After adding this value to the registry it started to work on my Windows 7 machine. This appears to be a Windows 7 issue.

I want to propose other one with using $.each:

1. We may to declare ajax function like:

   function ajaxFn(someData) {
       this.someData = someData;
       var that = this;
       return function () {
           var promise = $.Deferred();
           $.ajax({
               method: "POST",
               url: "url",
               data: that.someData,
               success: function(data) {
                   promise.resolve(data);
               },
               error: function(data) {
                   promise.reject(data);
               }
           })
           return promise;
       }
   }
   

2. Part of code where we creating array of functions with ajax to send:

   var arrayOfFn = [];
   for (var i = 0; i < someDataArray.length; i++) {
       var ajaxFnForArray = new ajaxFn(someDataArray[i]);
       arrayOfFn.push(ajaxFnForArray);
   }
   

3. And calling functions with sending ajax:

   $.when(
       $.each(arrayOfFn, function(index, value) {
           value.call()
       })
   ).then(function() {
           alert("Cheer!");
       }
   )
   

Use the following:

echo (text here) >> (name here).txt

Ex. echo my name is jeff >> test.txt

test.txt

my name is jeff

You can use it in a script too.

Try this!!

 override func viewDidLoad() {
   super.viewDidLoad()

   var button = UIButton.buttonWithType(.Custom) as UIButton
   button.frame = CGRectMake(160, 100, 200,40)

   button.layer.cornerRadius =5.0
   button.layer.borderColor = UIColor.redColor().CGColor
   button.layer.borderWidth = 2.0

   button.setImage(UIImage(named:"Placeholder.png"), forState: .Normal)
   button.addTarget(self, action: "OnClickroundButton", forControlEvents: .TouchUpInside)
   button.clipsToBounds = true

   view.addSubview(button)
}
    func OnClickroundButton() {
   NSLog(@"roundButton Method Called");
}

I used the following code to capture POST data that was submitted from form.php and then concatenate it onto a URL to send it BACK to the form for validation corrections. Works like a charm, and in effect converts POST data into GET data.

foreach($_POST as $key => $value) {
   $urlArray[] =  $key."=".$value;  
}
$urlString = implode("&", $urlArray);

echo "Please <a href='form.php?".$urlString."'>go back</a>";

Below code works for me

first I defined the partnerTypesMap like below in the server side,

Map<String, String> partnerTypes = new HashMap<>();

after adding values to it I added the object to model,

model.addAttribute("partnerTypesMap", partnerTypes);

When rendering the page I use below foreach to print them one by one.

<c:forEach items="${partnerTypesMap}" var="partnerTypesMap">
      <form:option value="${partnerTypesMap['value']}">${partnerTypesMap['key']}</form:option>
</c:forEach>

The following method may work:

git rebase HEAD master
git checkout master

This will rebase your current HEAD changes on top of the master. Then you can switch the branch.

Alternative way is to checkout the branch first:

git checkout master

Then Git should display SHA1 of your detached commits, then you can cherry pick them, e.g.

git cherry-pick YOURSHA1

Or you can also merge the latest one:

git merge YOURSHA1

To see all of your commits from different branches (to make sure you've them), run: git reflog.

WORKER TIMEOUT means your application cannot response to the request in a defined amount of time. You can set this using gunicorn timeout settings. Some application need more time to response than another.

Another thing that may affect this is choosing the worker type

The default synchronous workers assume that your application is resource-bound in terms of CPU and network bandwidth. Generally this means that your application shouldn’t do anything that takes an undefined amount of time. An example of something that takes an undefined amount of time is a request to the internet. At some point the external network will fail in such a way that clients will pile up on your servers. So, in this sense, any web application which makes outgoing requests to APIs will benefit from an asynchronous worker.

When I got the same problem as yours (I was trying to deploy my application using Docker Swarm), I've tried to increase the timeout and using another type of worker class. But all failed.

And then I suddenly realised I was limitting my resource too low for the service inside my compose file. This is the thing slowed down the application in my case

deploy:
  replicas: 5
  resources:
    limits:
      cpus: "0.1"
      memory: 50M
  restart_policy:
    condition: on-failure

So I suggest you to check what thing slowing down your application in the first place

The steps are very simple and it'll take just few mins. 1.Go to your C drive and in that go to the 'USER' section. 2.Under 'USER' section go to your 'name(e.g-'user1') and then find ".eclipse" folder and delete that folder 3.Along with that folder also delete "eclipse" folder and you can find that you're work has been done completely.

It was just designed that way. Increment and decrement operators are just shortcuts for x = x + 1. Python has typically adopted a design strategy which reduces the number of alternative means of performing an operation. Augmented assignment is the closest thing to increment/decrement operators in Python, and they weren't even added until Python 2.0.

Declare globally delayed listener:

var resize_timeout;

$(window).on('resize orientationchange', function(){
    clearTimeout(resize_timeout);

    resize_timeout = setTimeout(function(){
        $(window).trigger('resized');
    }, 250);
});

And below use listeners to resized event as you want:

$(window).on('resized', function(){
    console.log('resized');
});

You need to understand, the component hierarchy you are having and how you are passing props, definitely your case is special and not usually encountered by the devs.

Parent Component -myProp-> Child Component -myProp-> Grandchild Component

If myProp is changed in parent component it will be reflected in the child component too.

And if myProp is changed in child component it will be reflected in grandchild component too.

So if myProp is changed in parent component then it will be reflected in grandchild component. (so far so good).

Therefore down the hierarchy you don't have to do anything props will be inherently reactive.

Now talking about going up in hierarchy

If myProp is changed in grandChild component it won't be reflected in the child component. You have to use .sync modifier in child and emit event from the grandChild component.

If myProp is changed in child component it won't be reflected in the parent component. You have to use .sync modifier in parent and emit event from the child component.

If myProp is changed in grandChild component it won't be reflected in the parent component (obviously). You have to use .sync modifier child and emit event from the grandchild component, then watch the prop in child component and emit an event on change which is being listened by parent component using .sync modifier.

Let's see some code to avoid confusion

Parent.vue

<template>
    <div>
    <child :myProp.sync="myProp"></child>
    <input v-model="myProp"/>
    <p>{{myProp}}</p>
</div>
</template>

<script>

    import child from './Child.vue'

    export default{
        data(){
            return{
                myProp:"hello"
            }
        },
        components:{
            child
        }
    }
</script>

<style scoped>
</style>

Child.vue

<template>
<div>   <grand-child :myProp.sync="myProp"></grand-child>
    <p>{{myProp}}</p>
</div>

</template>

<script>
    import grandChild from './Grandchild.vue'

    export default{
        components:{
            grandChild
        },
        props:['myProp'],
        watch:{
            'myProp'(){
                this.$emit('update:myProp',this.myProp)

            }
        }
    }
</script>

<style>

</style>

Grandchild.vue

<template>
    <div><p>{{myProp}}</p>
    <input v-model="myProp" @input="changed"/>
    </div>
</template>

<script>
    export default{
        props:['myProp'],
        methods:{
            changed(event){
                this.$emit('update:myProp',this.myProp)
            }
        }
    }
</script>

<style>

</style>

But after this you wont help notice the screaming warnings of vue saying

'Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders.'

Again as I mentioned earlier most of the devs don't encounter this issue, because it's an anti pattern. That's why you get this warning.

But in order to solve your issue (according to your design). I believe you have to do the above work around(hack to be honest). I still recommend you should rethink your design and make is less prone to bugs.

I hope it helps.

This topic, especially the answer of Xotic750 was very helpful to me. I wanted to generate a json variable to pass it to a php script using ajax. My values were stored into two arrays, and i wanted them in json format. This is a generic example:

valArray1 = [121, 324, 42, 31];
valArray2 = [232, 131, 443];
myJson = {objArray1: {}, objArray2: {}};
for (var k = 1; k < valArray1.length; k++) {
    var objName = 'obj' + k;
    var objValue = valArray1[k];
    myJson.objArray1[objName] = objValue;
}
for (var k = 1; k < valArray2.length; k++) {
    var objName = 'obj' + k;
    var objValue = valArray2[k];
    myJson.objArray2[objName] = objValue;
}
console.log(JSON.stringify(myJson));

The result in the console Log should be something like this:

{
   "objArray1": {
        "obj1": 121,
        "obj2": 324,
        "obj3": 42,
        "obj4": 31
   },
   "objArray2": {
        "obj1": 232,
        "obj2": 131,
        "obj3": 443
  }
}

Jsfiddle: http://jsfiddle.net/guhokemk/1/

 function compare(dateTimeA, dateTimeB) {
    var momentA = moment(dateTimeA,"DD/MM/YYYY");
    var momentB = moment(dateTimeB,"DD/MM/YYYY");
    if (momentA > momentB) return 1;
    else if (momentA < momentB) return -1;
    else return 0;
}

alert(compare("11/07/2015", "10/07/2015"));

The method returns 1 if dateTimeA is greater than dateTimeB

The method returns 0 if dateTimeA equals dateTimeB

The method returns -1 if dateTimeA is less than dateTimeB

Verified: it works well in Docker 1.7.0.

Don't specify --pull=true when running the docker build command

From this thread on reference locally-built image using FROM at dockerfile:

If you want use the local image as the base image, pass without the option --pull=true
--pull=true will always attempt to pull a newer version of the image.

Ummm, you guys are forgetting the Character.isLetterOrDigit method:

boolean x;
String character = in.next();
char c = character.charAt(0);
if(Character.isLetterOrDigit(charAt(c)))
{ 
  x = true;
}

Another way of solving this problem is by not relying on the correct return value from the display but relying on the Android resources resolving.

Create the file layouts.xml in the folders res/values-land and res/values-port with the following content:

res/values-land/layouts.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <bool name="is_landscape">true</bool>
</resources>

res/values-port/layouts.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <bool name="is_landscape">false</bool>
</resources>

In your source code you can now access the current orientation as follows:

context.getResources().getBoolean(R.bool.is_landscape)

These files are from Maven wrapper. It works similarly to the Gradle wrapper.

This allows you to run the Maven project without having Maven installed and present on the path. It downloads the correct Maven version if it's not found (as far as I know by default in your user home directory).

The mvnw file is for Linux (bash) and the mvnw.cmd is for the Windows environment.

To create or update all necessary Maven Wrapper files execute the following command:

mvn -N io.takari:maven:wrapper

To use a different version of maven you can specify the version as follows:

mvn -N io.takari:maven:wrapper -Dmaven=3.3.3

Both commands require maven on PATH (add the path to maven bin to Path on System Variables) if you already have mvnw in your project you can use ./mvnw instead of mvn in the commands.

You are confusing regular expression with shell globbing. If you want to use regular expression to match file names you could do:

$ ls | egrep '.+\..+'

Delete the files under $hadoop_User/dfsdata and $hadoop_User/tmpdata then run:

hdfs namenode -format

finally run:

start-all.sh

Then your problem gets solved.

First of all select report file with rdlc extension and then go to View > Report Data

EXISTS (or NOT EXISTS) is specially designed for checking if something exists and therefore should be (and is) the best option. It will halt on the first row that matches so it does not require a TOP clause and it does not actually select any data so there is no overhead in size of columns. You can safely use SELECT * here - no different than SELECT 1, SELECT NULL or SELECT AnyColumn... (you can even use an invalid expression like SELECT 1/0 and it will not break).

IF EXISTS (SELECT * FROM Products WHERE id = ?)
BEGIN
--do what you need if exists
END
ELSE
BEGIN
--do what needs to be done if not
END

To create these constraints through the GUI you need the "indexes and keys" dialogue not the check constraints one.

But in your case you just need to run the piece of code you already have. It doesn't need to be entered into the expression dialogue at all.

You can implement a class that holds the fields you have in your JSON

class MyData
{
    public string t;
    public bool a;
    public object[] data;
    public string[][] type;
}

and then use the generic version of DeserializeObject:

MyData tmp = JsonConvert.DeserializeObject<MyData>(json);
foreach (string typeStr in tmp.type[0])
{
    // Do something with typeStr
}

jQuery normalises event.which depending on whether event.which, event.keyCode or event.charCode is supported by the browser:

// Add which for key events
if ( event.which == null && (event.charCode != null || event.keyCode != null) ) {
   event.which = event.charCode != null ? event.charCode : event.keyCode;
}

An added benefit of .which is that jQuery does it for mouse clicks too:

// Add which for click: 1 === left; 2 === middle; 3 === right
// Note: button is not normalized, so don't use it
if ( !event.which && event.button !== undefined ) {
    event.which = (event.button & 1 ? 1 : ( event.button & 2 ? 3 : ( event.button & 4 ? 2 : 0 ) ));
}

In Flask 1.1, if you return a dictionary and it will automatically be converted into JSON. So if make_summary() returns a dictionary, you can

from flask import Flask

app = Flask(__name__)

@app.route('/summary')
def summary():
    d = make_summary()
    return d

The SO that asks about including the status code was closed as a duplicate to this one. So to also answer that question, you can include the status code by returning a tuple of the form (dict, int). The dict is converted to JSON and the int will be the HTTP Status Code. Without any input, the Status is the default 200. So in the above example the code would be 200. In the example below it is changed to 201.

from flask import Flask

app = Flask(__name__)

@app.route('/summary')
def summary():
    d = make_summary()
    return d, 201  # 200 is the default

You can check the status code using

curl --request GET "http://127.0.0.1:5000/summary" -w "\ncode: %{http_code}\n\n"

Added for reference to future people who find this via google: You might want to look at the {% overextend %} tag provided by the mezzanine library for cases like this.

The assignment operator has lower precedence than &&, so your condition is equivalent to:

if ((match == 0 && k) = m)

But the left-hand side of this is an rvalue, namely the boolean resulting from the evaluation of the sub­expression match == 0 && k, so you cannot assign to it.

By contrast, comparison has higher precedence, so match == 0 && k == m is equivalent to:

if ((match == 0) && (k == m))

Use itertools.chain:

itertools.chain(*iterables):

Make an iterator that returns elements from the first iterable until it is exhausted, then proceeds to the next iterable, until all of the iterables are exhausted. Used for treating consecutive sequences as a single sequence.

Example:

from itertools import chain

A = [[1,2], [3,4]]

print list(chain(*A))
# or better: (available since Python 2.6)
print list(chain.from_iterable(A))

The output is:

[1, 2, 3, 4]

I have solved as plist file.

1. Add a NSAppTransportSecurity : Dictionary.
2. Add Subkey named " NSAllowsArbitraryLoads " as Boolean : YES

Connect to your server via SSH

then connect to your mysql console

and

USE user_base
REPAIR TABLE TABLE;

-OR-

If there are a lot of broken tables in current database:

mysqlcheck -uUSER -pPASSWORD  --repair --extended user_base

If there are a lot of broken tables in a lot of databases:

mysqlcheck -uUSER -pPASSWORD  --repair --extended -A

Use the which function:

A <- c('a','a','b','b','b')
B <- c(1,0,1,1,0)
d <- data.frame(A, B)

r <- with(d, which(B==0, arr.ind=TRUE))
newd <- d[-r, ]

You can use the --table or -t option, which will output a nice looking set of results

echo 'desc table_name' | mysql -uroot database -t

or some other method to pass a query to mysql, like:

mysql -uroot table_name --table < /tmp/somequery.sql

output:

If you specify ZEROFILL for a numeric column, MySQL automatically adds the UNSIGNED attribute to the column.

Numeric data types that permit the UNSIGNED attribute also permit SIGNED. However, these data types are signed by default, so the SIGNED attribute has no effect.

Above description is taken from MYSQL official website.

There is something wrong with your design. Try to make your classes represent real world things. For example:

• The class Card should represent one card, that is the nature of a "Card". The Card class does not need to know about Decks.
• The Deck class should contain 52 Card objects (plus jokers?).

Automated Tasks: Cron

Cron is a time-based scheduling service in Linux / Unix-like computer operating systems. Cron job are used to schedule commands to be executed periodically. You can setup commands or scripts, which will repeatedly run at a set time. Cron is one of the most useful tool in Linux or UNIX like operating systems. The cron service (daemon) runs in the background and constantly checks the /etc/crontab file, /etc/cron./* directories. It also checks the /var/spool/cron/ directory.

Configuring Cron Tasks

In the following example, the crontab command shown below will activate the cron tasks automatically every ten minutes:

*/10 * * * * /usr/bin/php /opt/test.php

In the above sample, the */10 * * * * represents when the task should happen. The first figure represents minutes – in this case, on every "ten" minute. The other figures represent, respectively, hour, day, month and day of the week.

* is a wildcard, meaning "every time".

Start with finding out your PHP binary by typing in command line:

whereis php

The output should be something like:

php: /usr/bin/php /etc/php.ini /etc/php.d /usr/lib64/php /usr/include/php /usr/share/php /usr/share/man/man1/php.1.gz

Specify correctly the full path in your command.

Type the following command to enter cronjob:

crontab -e

To see what you got in crontab.

EDIT 1:

To exit from vim editor without saving just click:

Shift+:

And then type q!

Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors at your server side.

You can fetch request using mode: 'cors'. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.

So in both condition you need to configure cors in your server or you need to use custom proxy server.

While there are suggestions above for "doing it the python way", if one wants to really have a logic based on EOF, then I suppose using exception handling is the way to do it --

try:
    line = raw_input()
    ... whatever needs to be done incase of no EOF ...
except EOFError:
    ... whatever needs to be done incase of EOF ...

Example:

$ echo test | python -c "while True: print raw_input()"
test
Traceback (most recent call last):
  File "<string>", line 1, in <module> 
EOFError: EOF when reading a line

Or press Ctrl-Z at a raw_input() prompt (Windows, Ctrl-Z Linux)

This Firefox add-on may work for you:

https://addons.mozilla.org/en-US/firefox/addon/cors-everywhere/

It can toggle CORS on and off for development purposes.

You need to remove the /var/lib/mysql folder. Also, purge when you remove the packages (I'm told this helps).

sudo apt-get remove --purge mysql-server mysql-client mysql-common

sudo rm -rf /var/lib/mysql

I was encountering similar issues. The second line got rid of my issues and allowed me to set up MySql from scratch. Hopefully it helps you too!

This works in MSSQL and MySQL:

SELECT *
FROM   Village
WHERE  CastleType LIKE '%foo%'; 

Regarding the alternative to super; you'd in most cases use use the base class either in the initialization list of the derived class, or using the Base::someData syntax when you are doing work elsewhere and the derived class redefines data members.

struct Base
{
    Base(char* name) { }
    virtual ~Base();
    int d;
};

struct Derived : Base
{
    Derived() : Base("someString") { }
    int d;
    void foo() { d = Base::d; }
};

I'd suggest try the change event? test to see if it has a value if it does then you can continue with your code. jQuery has

.bind("change", function(){ ... });

Or

.change(function(){ ... }); 

which are equivalents.

http://api.jquery.com/change/

for a unique selector change your name attribute to id and then jQuery("#imafile") or a general jQuery('input[type="file"]') for all the file inputs

Surprisingly no one told about this, which provides some !clarity:

style={{
backgroundColor: 'white',
opacity: 0.7
}}

The key checks for FAST REFRESH includes the following:

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

No 3 is easy to miss and worth highlighting here

This it's because the mongod process it's down, you must to run the commands bellow in order to get up the mongod process:

~$ sudo service mongodb stop

~$ sudo rm /var/lib/mongodb/mongod.lock

~$ sudo mongod --repair --dbpath /var/lib/mongodb

~$ sudo mongod --fork --logpath /var/lib/mongodb/mongodb.log --dbpath /var/lib/mongodb

~$ sudo service mongodb start

Hope this helps you.

You can use result.className = 'red';, but you can also use result.classList.add('red');. The .classList.add(str) way is usually easier if you need to add a class in general, and don't want to check if the class is already in the list of classes.

1. Create a new Text document and copy-paste the above code and save it as log4j2.xml.

2. Now copy this log4j2.xml file and paste it under your src folder of your Java project.

3. Run your java program again, you will see error is gone.

You can set the CSS of a notebook by calling a stylesheet from any cell. As an example, take a look at the 12 Steps to Navier Stokes course.

In particular, creating a file containing

<style>
    div.cell{
        width:100%;
        margin-left:1%;
        margin-right:auto;
    }
</style>

should give you a starting point. However, it may be necessary to also adjust e.g div.text_cell_render to deal with markdown as well as code cells.

If that file is custom.css then add a cell containing:

from IPython.core.display import HTML
def css_styling():
    styles = open("custom.css", "r").read()
    return HTML(styles)
css_styling()

This will apply all the stylings, and, in particular, change the cell width.

You might also consider removing the need for duplicated parameter names in your Sql by changing your Sql to

table.Variable2 LIKE '%' || :VarB || '%'

and then getting your client to provide '%' for any value of VarB instead of null. In some ways I think this is more natural.

You could also change the Sql to

table.Variable2 LIKE '%' || IfNull(:VarB, '%') || '%'

In my case I had to put the icon using:

toolbar.setNavigationIcon(R.drawable.ic_my_home);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);

And then listen to click events with default onOptionsItemSelected and android.R.id.home id

Hash tables are O(1) average and amortized case complexity, however it suffers from O(n) worst case time complexity. [And I think this is where your confusion is]

Hash tables suffer from O(n) worst time complexity due to two reasons:

1. If too many elements were hashed into the same key: looking inside this key may take O(n) time.
2. Once a hash table has passed its load balance - it has to rehash [create a new bigger table, and re-insert each element to the table].

However, it is said to be O(1) average and amortized case because:

1. It is very rare that many items will be hashed to the same key [if you chose a good hash function and you don't have too big load balance.
2. The rehash operation, which is O(n), can at most happen after n/2 ops, which are all assumed O(1): Thus when you sum the average time per op, you get : (n*O(1) + O(n)) / n) = O(1)

Note because of the rehashing issue - a realtime applications and applications that need low latency - should not use a hash table as their data structure.

EDIT: Annother issue with hash tables: cache
Another issue where you might see a performance loss in large hash tables is due to cache performance. Hash Tables suffer from bad cache performance, and thus for large collection - the access time might take longer, since you need to reload the relevant part of the table from the memory back into the cache.

You may use clone() which works well if your object has immutable objects and/or primitives, but it may be a little problematic when you don't have these ( such as collections ) for which you may need to perform a deep clone.

User userCopy = (User) user.clone();//make a copy

for(...) {
    user.age = 1;
    user.id = -1;

    UserDao.update(user)
    user = userCopy; 
}

It seems like you just want to preserve the attributes: age and id which are of type int so, why don't you give it a try and see if it works.

For more complex scenarios you could create a "copy" method:

publc class User { 
    public static User copy( User other ) {
         User newUser = new User();
         newUser.age = other.age;
         newUser.id = other.id;
         //... etc. 
         return newUser;
    }
}

It should take you about 10 minutes.

And then you can use that instead:

     User userCopy = User.copy( user ); //make a copy
     // etc.
