Unless the role was made dbo, db_owner or db_datawriter, it won't have permission to edit any data. If you want to grant full edit permissions to a single table, do this:

GRANT ALL ON table1 TO doctor 

Users in that role will have no permissions whatsoever to other tables (not even read).

CASE - 1

Using array.filter() We can get an array of objects which will match with our condition.
see the working example.

The error is because of the sql mode which can be strict mode as per latest MYSQL 5.7 documentation.

For more information read this.

Hope it helps.

I don't think desc takes an na.rm argument... I'm actually surprised it doesn't throw an error when you give it one. If you just want to remove NAs, use na.omit (base) or tidyr::drop_na:

outcome.df %>%
  na.omit() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

library(tidyr)
outcome.df %>%
  drop_na() %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

If you only want to remove NAs from the HeartAttackDeath column, filter with is.na, or use tidyr::drop_na:

outcome.df %>%
  filter(!is.na(HeartAttackDeath)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

outcome.df %>%
  drop_na(HeartAttackDeath) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

As pointed out at the dupe, complete.cases can also be used, but it's a bit trickier to put in a chain because it takes a data frame as an argument but returns an index vector. So you could use it like this:

outcome.df %>%
  filter(complete.cases(.)) %>%
  group_by(Hospital, State) %>%
  arrange(desc(HeartAttackDeath)) %>%
  head()

Try below piece of code.

Use ng-show and toggle the value of a show scope variable in the ng-click handler.

Here is a working example: http://jsfiddle.net/pvtpenguin/wD7gR/1/

<ul class="procedures">
    <li ng-repeat="procedure in procedures">
        <h4><a href="#" ng-click="show = !show">{{procedure.definition}}</a></h4>
         <div class="procedure-details" ng-show="show">
            <p>Number of patient discharges: {{procedure.discharges}}</p>
            <p>Average amount covered by Medicare: {{procedure.covered}}</p>
            <p>Average total payments: {{procedure.payments}}</p>
         </div>
    </li>
</ul>

I had same problem and the solution was very simple. Solution : foreign keys declared in table should not set to be not null.

reference : If you specify a SET NULL action, make sure that you have not declared the columns in the child table as NOT NULL. (ref )

The filter design method in accepted answer is correct, but it has a flaw. SciPy bandpass filters designed with b, a are unstable and may result in erroneous filters at higher filter orders.

Instead, use sos (second-order sections) output of filter design.

from scipy.signal import butter, sosfilt, sosfreqz

def butter_bandpass(lowcut, highcut, fs, order=5):
        nyq = 0.5 * fs
        low = lowcut / nyq
        high = highcut / nyq
        sos = butter(order, [low, high], analog=False, btype='band', output='sos')
        return sos

def butter_bandpass_filter(data, lowcut, highcut, fs, order=5):
        sos = butter_bandpass(lowcut, highcut, fs, order=order)
        y = sosfilt(sos, data)
        return y

Also, you can plot frequency response by changing

b, a = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = freqz(b, a, worN=2000)

to

sos = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = sosfreqz(sos, worN=2000)

easy

<script>
jQuery.noConflict()(document).ready(function() {
    $('#hide').css('display','none');
    $('#plano').change(function(){

        if(document.getElementById('plano').value == 1){
            $('#hide').show('slow');    

        }else 
            if(document.getElementById('plano').value == 0){

             $('#hide').hide('slow'); 
        }else
            if(document.getElementById('plano').value == 0){
             $('#hide').css('display','none');  

            }

    });
    $('#plano').change();
});

this example shows and hides the div if selected in combobox some specific value

GridView.Columns.Count will always be 0 when your GridView has its AutoGenerateColumns property set to true (default is true).

You can explicitly declare your columns and set the AutoGenerateColumns property to false, or you can use this in your codebehind:

GridView.Rows[0].Cells.Count

to get the column count once your GridView data has been bound, or this:

protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
    e.Row.Cells[index].Visible = false;
}

to set a column invisible using your GridView's RowDataBound event.

I had a similar problem. I ended up nuking it from orbit, and lost my SVN history in the process. But at least I made that damn error go away.

This is probably a sub-optimal sequence of commands to execute, but it should fairly closely follow the sequence of commands that I actually did to get things to work:

cp -rp target ~/other/location/target-20111108
svn rm target --force
cp -rp ~/other/location/target-20111108 target-other-name
cd target-other-name
find . -name .svn -print | xargs rm -rf
cd ..
svn add target-other-name
svn ci -m "Re-re-re-re-re-re-re-re-re-re import target"
svn mv target-other-name target
svn ci -m "Re-re-re-re-re-re-re-re-re-re import target"

Just to extend the answer above you can also index your columns rather than specifying the column names which can also be useful depending on what you're doing. Given that your location is the first field it would look like this:

    bar <- foo[foo[ ,1] == "there", ]

This is useful because you can perform operations on your column value, like looping over specific columns (and you can do the same by indexing row numbers too).

This is also useful if you need to perform some operation on more than one column because you can then specify a range of columns:

    foo[foo[ ,c(1:N)], ]

Or specific columns, as you would expect.

    foo[foo[ ,c(1,5,9)], ]

Some readers will have another issue and need this fix. read the links below. the same problem occured with visual studio 2015 with the advent of windows sdk 10 which brings up libucrt. ucrt is the windows implementation of C Runtime (CRT) aka the posix runtime library. You most likely have code that was ported from unix... Welcome to the drawback

Not answering the question, but you can also select by index, where i is the index of the item you wish to select:

var formObj = document.getElementById('myForm');
formObj.leaveCode[i].selected = true;

You can also loop through the items to select by display value with a loop:

for (var i = 0, len < formObj.leaveCode.length; i < len; i++) 
    if (formObj.leaveCode[i].value == 'xxx') formObj.leaveCode[i].selected = true;

First off, this actually is being raised in the next version to 8MB or 16MB ... but I think to put this into perspective, Eliot from 10gen (who developed MongoDB) puts it best:

EDIT: The size has been officially 'raised' to 16MB

So, on your blog example, 4MB is actually a whole lot.. For example, the full uncompresses text of "War of the Worlds" is only 364k (html): http://www.gutenberg.org/etext/36

If your blog post is that long with that many comments, I for one am not going to read it :)

For trackbacks, if you dedicated 1MB to them, you could easily have more than 10k (probably closer to 20k)

So except for truly bizarre situations, it'll work great. And in the exception case or spam, I really don't think you'd want a 20mb object anyway. I think capping trackbacks as 15k or so makes a lot of sense no matter what for performance. Or at least special casing if it ever happens.

-Eliot

I think you'd be pretty hard pressed to reach the limit ... and over time, if you upgrade ... you'll have to worry less and less.

The main point of the limit is so you don't use up all the RAM on your server (as you need to load all MBs of the document into RAM when you query it.)

So the limit is some % of normal usable RAM on a common system ... which will keep growing year on year.

Note on Storing Files in MongoDB

If you need to store documents (or files) larger than 16MB you can use the GridFS API which will automatically break up the data into segments and stream them back to you (thus avoiding the issue with size limits/RAM.)

Instead of storing a file in a single document, GridFS divides the file into parts, or chunks, and stores each chunk as a separate document.

GridFS uses two collections to store files. One collection stores the file chunks, and the other stores file metadata.

You can use this method to store images, files, videos, etc in the database much as you might in a SQL database. I have used this to even store multi gigabyte video files.

You may try this:

Page::where('id', $id)->update(array('image' => 'asdasd'));

There are other ways too but no need to use Page::find($id); in this case. But if you use find() then you may try it like this:

$page = Page::find($id);

// Make sure you've got the Page model
if($page) {
    $page->image = 'imagepath';
    $page->save();
}

Also you may use:

$page = Page::findOrFail($id);

So, it'll throw an exception if the model with that id was not found.

You can save the best model using keras.callbacks.ModelCheckpoint()

Example:

model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy'])
model_checkpoint_callback = keras.callbacks.ModelCheckpoint("best_Model.h5",save_best_only=True)
history = model.fit(x_train,y_train,
          epochs=10,
          validation_data=(x_valid,y_valid),
          callbacks=[model_checkpoint_callback])

This will save the best model in your working directory.

My first question is which version of SQL Server are you using (i.e 2005, 2008, 2008 R2, 2012)?

Assuming you are using 2008 or later SQL uses scope for variable determination. I believe 2005 still had global variables that would use @@variablename instead of @variable name which would define the difference between global and local variables. Starting in 2008 I believe this was changed to a scope defined variable designation structure. For example to create a global variable the @variable has to be defined at the start of a procedure, function, view, etc. In 2008 and later @@defined system variables for system functions I do believe. I could explain further if you explained the version and also where the variable is being defined, and the error that you are getting.

Worked for me after installing scipy.

If you used adb root, you would have got the following message:

C:\>adb root
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
restarting adbd as root

To get out of the root mode, you can use:

C:\>adb unroot
restarting adbd as non root

You don't have to override both __eq__ and __ne__ you can override only __cmp__ but this will make an implication on the result of ==, !==, < , > and so on.

is tests for object identity. This means a is b will be True in the case when a and b both hold the reference to the same object. In python you always hold a reference to an object in a variable not the actual object, so essentially for a is b to be true the objects in them should be located in the same memory location. How and most importantly why would you go about overriding this behaviour?

Edit: I didn't know __cmp__ was removed from python 3 so avoid it.

Basically, to make a cross domain AJAX requests, the requested server should allow the cross origin sharing of resources (CORS). You can read more about that from here: http://www.html5rocks.com/en/tutorials/cors/

In your scenario, you are setting the headers in the client which in fact needs to be set into http://localhost:8080/app server side code.

If you are using PHP Apache server, then you will need to add following in your .htaccess file:

Header set Access-Control-Allow-Origin "*"

You can use laravel MessageBag to add our own messages to existing messages.

To use MessageBag you need to use:

use Illuminate\Support\MessageBag;

In the controller:

MessageBag $message_bag

$message_bag->add('message', trans('auth.confirmation-success'));

return redirect('login')->withSuccess($message_bag);

Hope it will help some one.

You code is ok only except that you can't add same class test1.

$('.page-address-edit').addClass('test1').addClass('test2'); //this will add test1 and test2

And you could also do

$('.page-address-edit').addClass('test1 test2');

I would rather use plt.clf() after every plt.show() to just clear the current figure instead of closing and reopening it, keeping the window size and giving you a better performance and much better memory usage.

Similarly, you could do plt.cla() to just clear the current axes.

To clear a specific axes, useful when you have multiple axes within one figure, you could do for example:

fig, axes = plt.subplots(nrows=2, ncols=2)

axes[0, 1].clear()

There are several ways to do this. Both are very simple. Each of the examples works great. You can copy it into your project and test it.

The first method is preferable, the second is a bit outdated, but so far it works too.

There is another example which I would like to share with you
:D http://www.sommarskog.se/dynamic_sql.html#cursor0

If someone finds this question like me, here are my performance tests of proposed methods:

Python 2.7.8

In [1]: %timeit ([1]*1000000).insert(0, 0)
100 loops, best of 3: 4.62 ms per loop

In [2]: %timeit ([1]*1000000)[0:0] = [0]
100 loops, best of 3: 4.55 ms per loop

In [3]: %timeit [0] + [1]*1000000
100 loops, best of 3: 8.04 ms per loop

As you can see, insert and slice assignment are as almost twice as fast than explicit adding and are very close in results. As Raymond Hettinger noted insert is more common option and I, personally prefer this way to prepend to list.

No, there is no better way; yours is canonical.

I had this error and all the configurations mentioned above were correct however I was still getting "The client and service bindings may be mismatched" error.

What resolved my error, was matching the messageEncoding attribute values in the following node of service and client config files. They were different in mine, service was Text and client Mtom. Changing service to Mtom to match client's, resolved the issue.

<configuration>
  <system.serviceModel>
      <bindings>
           <basicHttpBinding>
              <binding name="BasicHttpBinding_IMySevice" ... messageEncoding="Mtom">
              ...
              </binding>
           </basicHttpBinding>
      </bindings>
  </system.serviceModel>
</configuration>

You can create a countdown timer using applet, below is the code,

   import java.applet.*;
   import java.awt.*;
   import java.awt.event.*;
   import javax.swing.*;
   import javax.swing.Timer; // not java.util.Timer
   import java.text.NumberFormat;
   import java.net.*;



/**
    * An applet that counts down from a specified time. When it reaches 00:00,
    * it optionally plays a sound and optionally moves the browser to a new page.
    * Place the mouse over the applet to pause the count; move it off to resume.
    * This class demonstrates most applet methods and features.
    **/

String strJson="{\"Employee\":
[{\"id\":\"101\",\"name\":\"Pushkar\",\"salary\":\"5000\"},
{\"id\":\"102\",\"name\":\"Rahul\",\"salary\":\"4000\"},
{\"id\":\"103\",\"name\":\"tanveer\",\"salary\":\"56678\"}]}";

This is an example of a JSON string with Employee as object, then multiple strings and values in an array as a reference to @cregox...

A bit complicated but can explain a lot in a single JSON string.

The prestListView.getItemAtPosition(position); returns the UI widget: Text, Icon, ...

Try this instead:

Object o = prestationAdapterEco.getItemAtPosition(position);

or

Object o = arg0.getItemAtPosition(position);

Get the object from the adapter. Not from the list-view.

2. Object o is a prestationEco object. Not a String.

you can use program like tcpview from sysinternal. I guess it can help you a lot on both monitoring and killing unwanted connection.

int iInt = 10;
Integer iInteger = new Integer(iInt);

with GNU-grep you could just say

grep --context=10 ...

The AngularJS documentation on directives is pretty well written for what the symbols mean.

To be clear, you cannot just have

scope: '@'

in a directive definition. You must have properties for which those bindings apply, as in:

scope: {
    myProperty: '@'
}

I strongly suggest you read the documentation and the tutorials on the site. There is much more information you need to know about isolated scopes and other topics.

Here is a direct quote from the above-linked page, regarding the values of scope:

The scope property can be true, an object or a falsy value:

• falsy: No scope will be created for the directive. The directive will use its parent's scope.

• true: A new child scope that prototypically inherits from its parent will be created for the directive's element. If multiple directives on the same element request a new scope, only one new scope is created. The new scope rule does not apply for the root of the template since the root of the template always gets a new scope.

• {...} (an object hash): A new "isolate" scope is created for the directive's element. The 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent scope. This is useful when creating reusable components, which should not accidentally read or modify data in the parent scope.

Try this . . .

Code snippet:

 NSDateComponents *components = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate:[NSDate date]];
 int year = [components year];
 int month = [components month];
 int day = [components day];

It gives current year, month, date

If the problem is to find whether the phone's network is connected and fast enough to meet your demands you have to handle all the network types returned by getSubType().

It took me an hour or two to research and write this class to do just exactly that, and I thought I would share it with others that might find it useful.

Here is a Gist of the class, so you can fork it and edited it.

Not sure if that's exactly what you need, but we are using profiles to define the environment we are running at and specific bean for each environment, so it's something like that:

<bean name="myBean" class="myClass">
    <constructor-arg name="name" value="originalValue" />
</bean>
<beans profile="DEV, default">
     <!-- Specific DEV configurations, also default if no profile defined -->
    <bean name="myBean" class="myClass">
        <constructor-arg name="name" value="overrideValue" />
    </bean>
</beans>
<beans profile="CI, UAT">
     <!-- Specific CI / UAT configurations -->
</beans>
<beans profile="PROD">
     <!-- Specific PROD configurations -->
</beans>

So in this case, if I don't define a profile or if I define it as "DEV" myBean will get "overrideValue" for it's name argument. But if I set the profile to "CI", "UAT" or "PROD" it will get "originalValue" as the value.

Provide the source image (img) size as the first rectangle:

ctx.drawImage(img, 0, 0, img.width,    img.height,     // source rectangle
                   0, 0, canvas.width, canvas.height); // destination rectangle

The second rectangle will be the destination size (what source rectangle will be scaled to).

Update 2016/6: For aspect ratio and positioning (ala CSS' "cover" method), check out:

I think I see your problem, you need to use the @ syntax to define parameters you will pass in this way, also I'm not sure what loginID or password are doing you don't seem to define them anywhere and they are not being used as URL parameters so are they being sent as query parameters?

This is what I can suggest based on what I see so far:

.factory('MagComments', function ($resource) {
    return $resource('http://localhost/dooleystand/ci/api/magCommenct/:id', {
      loginID : organEntity,
      password : organCommpassword,
      id : '@magId'
    });
  })

The @magId string will tell the resource to replace :id with the property magId on the object you pass it as parameters.

I'd suggest reading over the documentation here (I know it's a bit opaque) very carefully and looking at the examples towards the end, this should help a lot.

Configuration worked with Eclipse Mars 4.5 version.

1) Install Eclipse Mars 4.5 from https://eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/mars2 This comes with Tern and embedded Node.js server

2) Install AngularJS Eclipse plugin from Eclipse Marketplace

3) Configure node.js server to the embedded nodejs server within Eclipse (found in the eclipse plugins folder) at Windows-> Preferences -> JavaScript -> Tern -> Server -> node.js. No extra configurations are required.

4) Test configuration in a html or javascript file. https://github.com/angelozerr/angularjs-eclipse

A web-application is an application that is hosted on the internet. It can have a front-end or user-interface on a web-site.

Hope that helps.

It just associates a semaphore with every object, and uses that.

Note that if you need to deal with multi-byte characters, i.e. if you have to internationalize your site, the s[0] = ... solution won't be adequate. This Stack Overflow question suggests using the unicode-util gem

Ruby 1.9: how can I properly upcase & downcase multibyte strings?

EDIT

Actually an easier way to at least avoid strange string encodings is to just use String#mb_chars:

s = s.mb_chars
s[0] = s.first.upcase
s.to_s

If you mean that you can do this:

CREATE TABLE mytable_d (
ID          TINYINT NOT NULL AUTO_INCREMENT PRIMARY KEY,
Name        VARCHAR(255) NOT NULL,
UNIQUE(Name)
) ENGINE=InnoDB;


ALTER TABLE mytable
ADD COLUMN DID tinyint(5) NOT NULL,
ADD CONSTRAINT mytable_ibfk_4 
      FOREIGN KEY (DID) 
        REFERENCES mytable_d (ID) ON DELETE CASCADE;

 > OK.

But then:

ALTER TABLE mytable
DROP KEY AID ;

gives error.

You can drop the index and create a new one in one ALTER TABLE statement:

ALTER TABLE mytable
DROP KEY AID ,
ADD UNIQUE KEY AID (AID, BID, CID, DID);

Your @POST method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:

@XmlRootElement
public class MyJaxBean {
    @XmlElement public String param1;
    @XmlElement public String param2;
}

Then your @POST method would look like the following:

@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
    System.out.println("param1 = " + input.param1);
    System.out.println("param2 = " + input.param2);
}

This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input in this case. The actual message would look something like:

POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com

{"param1":"hello","param2":"world"}

Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.

HTML <FORM>

The parameters would be annotated using @FormParam:

@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
                   @FormParam("param2") String param2) {
    ...
}

The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:

POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25

param1=hello&param2=world

The content is URL encoded in this case.

If you do not know the names of the FormParam's you can do the following:

@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
    ...
}

HTTP Headers

You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:

@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
                   @HeaderParam("param2") String param2) {
    ...
}

Here's what the HTTP message would look like. Note that this POST does not have a body.

POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world

I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.

HTTP Query Parameters

This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.

@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
                   @QueryParam("param2") String param2) {
    ...
}

Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:

POST /create?param1=hello&param2=world HTTP/1.1

You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.

HTTP Path Parameters

Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:

@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
                   @PathParam("param2") String param2) {
    ...
}

The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.

POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com

This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.

As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM-based HTML pages, then use @FormParam. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.

Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.

You don't need hibernate-entitymanager-xxx.jar, because of you use a Hibernate session approach (not JPA). You need to close the SessionFactory too and rollback a transaction on errors. But, the problem, of course, is not with those.

While a comprehensive answer to this question takes up hundreds of pages of my book, here's a quick comparison chart that I'm still working on:

Imho, most straightforward and universal code:

dft=within(dft,{
    y=NA
    y[x %in% c('a','b','c')]='abc'

With Apache, if you make a php script on your local machine calling your executable, and then call this script via POST or GET via html/javascript?

would it function?

Rails users (from the omniauth-google-oauth2 docs):

Fixing Protocol Mismatch for redirect_uri in Rails

Just set the full_host in OmniAuth based on the Rails.env.

# config/initializers/omniauth.rb

OmniAuth.config.full_host = Rails.env.production? ? 'https://domain.com' : 'http://localhost:3000'

REMEMBER: Do not include the trailing "/"

If rm cannot remove a symlink, perhaps you need to look at the permissions on the directory that contains the symlink. To remove directory entries, you need write permission on the containing directory.

This will validate against special characters and leading and trailing spaces:

var strString = "Your String";

strString.match(/^[A-Za-z0-9][A-Za-z0-9 ]\*[A-Za-z0-9]\*$/)

Another place I've seen this error is when your project has multiple targets AND multiple bridging headers. If it's a shared class, make sure you add the resource to all bridging headers.

A good tip to is to look in the left Issue Navigator panel; the root object will show the target that is issuing the complaint.

For my case, Xcode 8.2.1, I had a Map Kit View in a view controller. So I went to

Build Phases > Link Binary With Libraries

and added MapKit.framework, then it was fine.

I think this will also apply to other views that require framework.

P.S. Running on iOS 9 told me that there was an issue about Map Kit View, while on iOS 10 told me nothing!

Use the system_profiler | grep "Cores" command.

I have a:

MacBook Pro Retina, Mid 2012.

Processor: 2.6 GHz Intel Core i7

user$ system_profiler | grep "Cores"
      Total Number of Cores: 4

user$ sysctl -n hw.ncpu
8

According to Wikipedia, (http://en.wikipedia.org/wiki/Intel_Core#Core_i7) there is no Core i7 with 8 physical cores so the Hyperthreading idea must be the case. Ignore sysctl and use the system_profiler value for accuracy. The real question is whether or not you can efficiently run applications with 4 cores (long compile jobs?) without interrupting other processes.

Running a compiler parallelized with 4 cores doesn't appear to dramatically affect regular OS operations. So perhaps treating it as 8 cores is not so bad.

You can also use := construct to assign and decide on action in one step. Consider following example:

# Example of setting default server and reporting it's status

server=$1
if [[ ${server:=localhost} =~ [a-z] ]]      # 'localhost' assigned here to $server
then    echo "server is localhost"          # echo is triggered since letters were found in $server
else
        echo "server was set" # numbers were passed
fi

If $1 is not empty, localhost will be assigned to server in the if condition field, trigger match and report match result. In this way you can assign on the fly and trigger appropriate action.

The closest equivalent to Java's toString is to implement __str__ for your class. Put this in your class definition:

def __str__(self):
     return "foo"

You may also want to implement __repr__ to aid in debugging.

See here for more information:

• Special Method Names - Basic Customization

history | tail -2 | head -1 | cut -c8-999

tail -2 returns the last two command lines from history head -1 returns just first line cut -c8-999 returns just command line, removing PID and spaces.

Note that the way the git credential helper "store" will store the unencrypted passwords changes with Git 2.5+ (Q2 2014).
See commit 17c7f4d by Junio C Hamano (gitster)

credential-xdg

Tweak the sample "store" backend of the credential helper to honor XDG configuration file locations when specified.

The doc now say:

If not specified:

• credentials will be searched for from ~/.git-credentials and $XDG_CONFIG_HOME/git/credentials, and
• credentials will be written to ~/.git-credentials if it exists, or $XDG_CONFIG_HOME/git/credentials if it exists and the former does not.

Caution, member enumeration only works if the collection itself has no member of the same name. So if you had an array of FileInfo objects, you couldn't get an array of file lengths by using

 $files.length # evaluates to array length

And before you say "well obviously", consider this. If you had an array of objects with a capacity property then

 $objarr.capacity

would work fine UNLESS $objarr were actually not an [Array] but, for example, an [ArrayList]. So before using member enumeration you might have to look inside the black box containing your collection.

(Note to moderators: this should be a comment on rageandqq's answer but I don't yet have enough reputation.)

Had the same issue, but executing the queries alone will not help. To fix this I did the following,

1. Set old_passwords=0 in my.cnf file
2. Restart mysql
3. Login to mysql as root user
4. Execute FLUSH PRIVILEGES;

while true ; do
    ...
    if [ something ]; then
        break
    fi
done

This should work.

Dynamically changing styles is not supported (yet). You have to set the style before the view gets created, via XML.

See man git-add:

   -f, --force
       Allow adding otherwise ignored files.

So run this

git add --force my/ignore/file.foo

You can use nested routes

Django <1.8

urlpatterns = patterns(''
    url(r'^project_config/', include(patterns('',
        url(r'^$', ProjectConfigView.as_view(), name="project_config")
        url(r'^(?P<product>\w+)$', include(patterns('',
            url(r'^$', ProductView.as_view(), name="product"),
            url(r'^(?P<project_id>\w+)$', ProjectDetailView.as_view(), name="project_detail")
        ))),
    ))),
)

Django >=1.8

urlpatterns = [
    url(r'^project_config/', include([
        url(r'^$', ProjectConfigView.as_view(), name="project_config")
        url(r'^(?P<product>\w+)$', include([
            url(r'^$', ProductView.as_view(), name="product"),
            url(r'^(?P<project_id>\w+)$', ProjectDetailView.as_view(), name="project_detail")
        ])),
    ])),
]

This is a lot more DRY (Say you wanted to rename the product kwarg to product_id, you only have to change line 4, and it will affect the below URLs.

Edited for Django 1.8 and above

Is there some command to create this folder?

If smb face this issue again, you should know the most simple way to create .m2 folder.
If you unzipped maven and set up maven path variable - just try mvn clean command from anywhere you like!
Dont be afraid of error messages when running - it works and creates needed directory.

You need, for example:

<input type="text" name="idtest" value="<?php echo $idtest; ?>" />

The echo function is what actually outputs the value of the variable.

Another reason to be carefully when pass an Optional as parameter is that a method should do one thing... If you pass an Optional param you could favor do more than one thing, it could be similar to pass a boolean param.

public void method(Optional<MyClass> param) {
     if(param.isPresent()) {
         //do something
     } else {
         //do some other
     }
 }

I have come to the same problem and fixed the same way as Alex K.

So if "Send Errors To Browser" is not working set also this:

Error Pages -> 500 -> Edit Feature Settings -> "Detailed Errors"

Also note that if the content of the error page sent back is quite short and you're using IE, IE will happily ignore the useful content sent back by the server and show you its own generic error page instead. You can turn this off in IE's options, or use a different browser.

One of the putty tools is pscp.exe; it will allow you to copy files from your remote host.

You must use the name of the subform control, not the name of the subform, though these are often the same:

 Forms![MainForm]![subform control name Name].Form.Requery

Or, if you are on the main form:

 Me.[subform control name Name].Form.Requery

You can append a queryString to your src and change it only when you will release an updated version:

<script src="test.js?v=1"></script>

In this way the browser will use the cached version until a new version will be specified (v=2, v=3...)

npm install google-closure-library --save

require("google-closure-library");
goog.require('goog.crypt.base64');

var result =goog.crypt.base64.encodeByteArray(Uint8Array.of(1,83,27,99,102,66));
console.log(result);

$node index.js would write AVMbY2Y= to the console.

Angular 2 and Angular 4 

In a ngFor loop it must be look like this:

<div class="column" *ngFor="let u of events ">
                <div class="thumb">
                    <img src="assets/uploads/{{u.image}}">
                    <h4>{{u.name}}</h4>
                </div>
                <div class="info">
                    <img src="assets/uploads/{{u.image}}">
                    <h4>{{u.name}}</h4>
                    <p>{{u.text}}</p>
                </div>
            </div>

This is a way:

values = [1, 2, 3]
Foo.__table__.insert().execute([{'bar': x} for x in values])

This will insert like this:

INSERT INTO `foo` (`bar`) VALUES (1), (2), (3)

Reference: The SQLAlchemy FAQ includes benchmarks for various commit methods.

To assign, you should use p=p+1; instead of p+1=p;

int main()
{

   int x[3]={4,5,6};
   int *p=x;
   p=p+1; /*You just needed to switch the terms around*/
   cout<<p<<endl;
   getch();
}

Another useful way is with Concat.
More information in the official documentation.

List<string> first = new List<string> { "One", "Two", "Three" };
List<string> second = new List<string>() { "Four", "Five" };
first.Concat(second);

The output will be.

One
Two
Three
Four
Five

And there is another similar answer.

By definition "A Set is a collection of values, where each value may occur only once." So, if your array has repeated values then only one value among the repeated values will be added to your Set.

var arr = [1, 2, 3];
var set = new Set(arr);
console.log(set); // {1,2,3}


var arr = [1, 2, 1];
var set = new Set(arr);
console.log(set); // {1,2}

So, do not convert to set if you have repeated values in your array.

here is how I've done this before.

1. put a dummy column "X" off to the right of your source pivot table.
2. click in that cell and start your pivot table.
3. once the dialogue box pops up you can edit the data range to include your pivot table.
4. this may require you to Refresh the source table first and then refresh your secondary pivot table...or do refresh all twice

create table like this,

CommentId    UserId
---------------------
   1            usr1
   1            usr2

In this way you can check whether the user posted the comments are not.. Apart from this there should be tables for Comments and Users with respective id's

$(document).ready(function () {
  $('input[type="text"]').blur(function () {
    if (!$(this).val()) {
      $(this).addClass('error');
    } else {
      $(this).removeClass('error');
    }
  });
});


<style>
 .error {
   border: 1px solid #ff0000;
 }
</style>

Here the way the working of HTML file with Jquery.

 _webview=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, 320, 568)];
    [self.view addSubview:_webview];

    NSString *filePath=[[NSBundle mainBundle]pathForResource:@"jquery" ofType:@"html" inDirectory:nil];

    NSLog(@"%@",filePath);
    NSString *htmlstring=[NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];

    [_webview loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:filePath]]];
                         or
    [_webview loadHTMLString:htmlstring baseURL:nil];

You can use either the requests to call the HTML file in your UIWebview

When using setAttribute and getRequestDispatcher on doGet, make sure that you are accessing your pages with the urlPatterns ("/login" for example) defined for your servlet. If you do it with "/login.jsp" your doGet won't get called so none of your attributes will be available.

For website developers, another option you have is to follow a working Facebook Graph API tutorial such as this one.

But if you need a quick solution where you can customize and embed a Facebook page feed instantly, you should use website plugins such as this one.

Here's a step by step guide:

1. Get a Free Key or Paid Key.
2. Go to this login page and use the key to login.
3. Once logged in, click “+ Create Custom Feed” button.
4. On the pop up, name your custom Facebook page feed.
5. On the drop-down, select “Facebook Page Feed On Your Website” option.
6. Enter your Facebook Page ID.
7. Click the “Proceed” button. This will show you the customization options.
8. Click the “ Embed On Website” button located on the upper-right corner of the screen.
9. On the pop up, copy the embed code by clicking the “Copy Code” button.
10. Paste the embed code on your website.

Visit the tutorial link to see a live demo there as well.

I got here searching for a way to execute some code whenever the program ends.
Found this:

Called multiple times will register multiple handlers.

You are populating your dictionaries with references to a single list so when you update it, the update is reflected across all the references. Try a dictionary comprehension instead. See Create a dictionary with list comprehension in Python

d = {k : v for k in blah blah blah}

Basically copying and pasting from Bjarne Stroustrup's "The C++ Programming Language 4th Edition":

List initialization does not allow narrowing (§iso.8.5.4). That is:

• An integer cannot be converted to another integer that cannot hold its value. For example, char to int is allowed, but not int to char.
• A floating-point value cannot be converted to another floating-point type that cannot hold its value. For example, float to double is allowed, but not double to float.
• A floating-point value cannot be converted to an integer type.
• An integer value cannot be converted to a floating-point type.

Example:

void fun(double val, int val2) {

    int x2 = val;    // if val == 7.9, x2 becomes 7 (bad)

    char c2 = val2;  // if val2 == 1025, c2 becomes 1 (bad)

    int x3 {val};    // error: possible truncation (good)

    char c3 {val2};  // error: possible narrowing (good)

    char c4 {24};    // OK: 24 can be represented exactly as a char (good)

    char c5 {264};   // error (assuming 8-bit chars): 264 cannot be 
                     // represented as a char (good)

    int x4 {2.0};    // error: no double to int value conversion (good)

}

The only situation where = is preferred over {} is when using auto keyword to get the type determined by the initializer.

Example:

auto z1 {99};   // z1 is an int
auto z2 = {99}; // z2 is std::initializer_list<int>
auto z3 = 99;   // z3 is an int

Conclusion

Prefer {} initialization over alternatives unless you have a strong reason not to.

Multiple SQL statements must be executed with the mysqli_multi_query() function.

Example (MySQLi Object-oriented):

    <?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "INSERT INTO names (firstname, lastname)
VALUES ('inpute value here', 'inpute value here');";
$sql .= "INSERT INTO phones (landphone, mobile)
VALUES ('inpute value here', 'inpute value here');";

if ($conn->multi_query($sql) === TRUE) {
    echo "New records created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>

Since Python 3.5 you can unpack unlimited amount of lists.

if you give a 2D array to the plot function of matplotlib it will assume the columns to be lines:

If x and/or y is 2-dimensional, then the corresponding columns will be plotted.

In your case your shape is not accepted (100, 1, 1, 8000). As so you can using numpy squeeze to solve the problem quickly:

np.squeez doc: Remove single-dimensional entries from the shape of an array.

import numpy as np
import matplotlib.pyplot as plt

data = np.random.randint(3, 7, (10, 1, 1, 80))
newdata = np.squeeze(data) # Shape is now: (10, 80)
plt.plot(newdata) # plotting by columns
plt.show()

But notice that 100 sets of 80 000 points is a lot of data for matplotlib. I would recommend that you look for an alternative. The result of the code example (run in Jupyter) is:

try this line of code.

textview.setTypeface(textview.getTypeface(), Typeface.DEFAULT_BOLD);

here , it will get current Typeface from this textview and replace it using new Typeface. New typeface here is DEFAULT_BOLD but you can apply many more.

The best one that I found is http://www.favicomatic.com/ I say best because it gave me the crispest favicon, and required no editing after their transformation. It will generate favicons at 16x16 and 32x32 and to quote them "Every damn size, sir!" Also, their site looks cool and is easy to use.

They also generate the html that you need to use for the files they generate.

I looked at the first 20 or so google results, and this was by far the best.

Serialization is the process of converting an object's state to bits so that it can be stored on a hard drive. When you deserialize the same object, it will retain its state later. It lets you recreate objects without having to save the objects' properties by hand.

http://en.wikipedia.org/wiki/Serialization

You test k = M instead of k == M.
Maybe it is what you want to do, in this case, write if (match == 0 && (k = M))

my case: I used relative dir

       location ~* \.(css|js)\.php$ {

            root ../dolibarr/htdocs;

            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

            fastcgi_param SCRIPT_NAME $fastcgi_script_name;
            fastcgi_index index.php;

             include /etc/nginx/fastcgi_params;
       }

this line did not work too : fastcgi_param SCRIPT_FILENAME /vagrant/www/p1/../p2/htdocs/core/js/lib_head.js.php;

So I discovered fastcgi_param does not support relative path.

This works

fastcgi_param SCRIPT_FILENAME /vagrant/www/p2/htdocs/core/js/lib_head.js.php;

you can use

select cast((630/60.0) as  decimal(16,2))

import json
row = [1L,[0.1,0.2],[[1234L,1],[134L,2]]]
row_json = json.dumps(row)

There are a couple of parallization bugs in SQL server with abnormal input. OPTION(MAXDOP 1) will sidestep them.

EDIT: Old. My testing was done largely on SQL 2005. Most of these seem to not exist anymore, but every once in awhile we question the assumption when SQL 2014 does something dumb and we go back to the old way and it works. We never managed to demonstrate that it wasn't just a bad plan generation on more recent cases though since SQL server can be relied on to get the old way right in newer versions. Since all cases were IO bound queries MAXDOP 1 doesn't hurt.

INSERT INTO Destination SELECT * FROM Source;

See SQL As Understood By SQLite: INSERT for a formal definition.

moment("01:15:00 PM", "h:mm:ss A").format("HH:mm:ss")
**o/p: 13:15:00 **

it will give convert 24 hrs format to 12 hrs format.

From the answers above I build this with Angular 5.x

Just call uploadFile(url, file).subscribe() to trigger an upload

import { Injectable } from '@angular/core';
import {HttpClient, HttpParams, HttpRequest, HttpEvent} from '@angular/common/http';
import {Observable} from "rxjs";

@Injectable()
export class UploadService {

  constructor(private http: HttpClient) { }

  // file from event.target.files[0]
  uploadFile(url: string, file: File): Observable<HttpEvent<any>> {

    let formData = new FormData();
    formData.append('upload', file);

    let params = new HttpParams();

    const options = {
      params: params,
      reportProgress: true,
    };

    const req = new HttpRequest('POST', url, formData, options);
    return this.http.request(req);
  }
}

Use it like this in your component

  // At the drag drop area
  // (drop)="onDropFile($event)"
  onDropFile(event: DragEvent) {
    event.preventDefault();
    this.uploadFile(event.dataTransfer.files);
  }

  // At the drag drop area
  // (dragover)="onDragOverFile($event)"
  onDragOverFile(event) {
    event.stopPropagation();
    event.preventDefault();
  }

  // At the file input element
  // (change)="selectFile($event)"
  selectFile(event) {
    this.uploadFile(event.target.files);
  }

  uploadFile(files: FileList) {
    if (files.length == 0) {
      console.log("No file selected!");
      return

    }
    let file: File = files[0];

    this.upload.uploadFile(this.appCfg.baseUrl + "/api/flash/upload", file)
      .subscribe(
        event => {
          if (event.type == HttpEventType.UploadProgress) {
            const percentDone = Math.round(100 * event.loaded / event.total);
            console.log(`File is ${percentDone}% loaded.`);
          } else if (event instanceof HttpResponse) {
            console.log('File is completely loaded!');
          }
        },
        (err) => {
          console.log("Upload Error:", err);
        }, () => {
          console.log("Upload done");
        }
      )
  }

I know it is wery late, but I fonded this project and I would like to share with you, it is very usefull and sample Simple Display Dialog of Waiting in WinForms

The effect of the 301 would be that the search engines will index /option-a instead of /option-x. Which is probably a good thing since /option-x is not reachable for the search index and thus could have a positive effect on the index. Only if you use this wisely ;-)

After the redirect put exit(); to stop the rest of the script to execute

header("HTTP/1.1 301 Moved Permanently"); 
header("Location: /option-a"); 
exit();

Update July 1st 2019

docker-compose logs <name-of-service>

From the documentation:

Usage: logs [options] [SERVICE...]

Options:

--no-color Produce monochrome output.

-f, --follow Follow log output.

-t, --timestamps Show timestamps.

--tail="all" Number of lines to show from the end of the logs for each container.

See docker logs

You can start Docker compose in detached mode and attach yourself to the logs of all container later. If you're done watching logs you can detach yourself from the logs output without shutting down your services.

1. Use docker-compose up -d to start all services in detached mode (-d) (you won't see any logs in detached mode)
2. Use docker-compose logs -f -t to attach yourself to the logs of all running services, whereas -f means you follow the log output and the -t option gives you timestamps (See Docker reference)
3. Use Ctrl + z or Ctrl + c to detach yourself from the log output without shutting down your running containers

If you're interested in logs of a single container you can use the docker keyword instead:

1. Use docker logs -t -f <name-of-service>

Save the output

To save the output to a file you add the following to your logs command:

1. docker-compose logs -f -t >> myDockerCompose.log

Better just create a XLSX file with field names on top row. Create it manually or using Mockaroo. Export it to Excel(or CSV) and then import it to Access using New Data Source -> From File

IMHO it's the best and most performant way to do it in Access.

It may help you somehow.

String st="I am am not the one who is thinking I one thing at time";
String []ar = st.split("\\s");
Map<String, Integer> mp= new HashMap<String, Integer>();

    count=0;

    for(int j=0;j<ar.length;j++){
        if(ar[i].equals(ar[j])){
        count++;                
        }
    }

    mp.put(ar[i], count);
}

System.out.println(mp);

I wasn't using Azure, but I got the same error locally. Using <customErrors mode="Off" /> seemed to have no effect, but checking the Application logs in Event Viewer revealed a warning from ASP.NET which contained all the detail I needed to resolve the issue.

From stack trace:

HikariPool: Timeout failure pool HikariPool-0 stats (total=20, active=20, idle=0, waiting=0) Means pool reached maximum connections limit set in configuration.

The next line: HikariPool-0 - Connection is not available, request timed out after 30000ms. Means pool waited 30000ms for free connection but your application not returned any connection meanwhile.

Mostly it is connection leak (connection is not closed after borrowing from pool), set leakDetectionThreshold to the maximum value that you expect SQL query would take to execute.

otherwise, your maximum connections 'at a time' requirement is higher than 20 !

Open up terminal and check what java version is currently set in your path variable.

You can do that by typing in your terminal

java -version // this will check your jre version. 
javac -version // this will check your compiler version

If this shows incorrect java version but you have installed java 1.8 then you have to set path variable to the newer version of java.

To do that do add the line:

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

to ~/.bash_profile (same as /Users/username/.bash_profile)

Then do this from the terminal to set the new variable

source ~/.bash_profile

Also what's your eclipse.ini set to ?

-Dosgi.requiredJavaVersion=1.7

EDIT:

Please open up terminal and type

 find / -name "java" // This should find all folder named java on your file system.

Also how did you install java in the first place ?

Is there a way in which I can update the plot just by adding more point[s] to it...

There are a number of ways of animating data in matplotlib, depending on the version you have. Have you seen the matplotlib cookbook examples? Also, check out the more modern animation examples in the matplotlib documentation. Finally, the animation API defines a function FuncAnimation which animates a function in time. This function could just be the function you use to acquire your data.

Each method basically sets the data property of the object being drawn, so doesn't require clearing the screen or figure. The data property can simply be extended, so you can keep the previous points and just keep adding to your line (or image or whatever you are drawing).

Given that you say that your data arrival time is uncertain your best bet is probably just to do something like:

import matplotlib.pyplot as plt
import numpy

hl, = plt.plot([], [])

def update_line(hl, new_data):
    hl.set_xdata(numpy.append(hl.get_xdata(), new_data))
    hl.set_ydata(numpy.append(hl.get_ydata(), new_data))
    plt.draw()

Then when you receive data from the serial port just call update_line.

The simplest way to do this is by

df["DateColumn"] = (df["DateColumn"]).dt.days

Below code for best examples for nested loops, while using two for loops please remember the output of the first loop is input for the second loop. Loop termination also important while using the nested loops

for x in range(1, 10, 1):
     for y in range(1,x):
             print y,
        print
OutPut :
1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4 5 6
1 2 3 4 5 6 7
1 2 3 4 5 6 7 8

Well, technically any such object will wind up being built over a C-style thread library because C++ only just specified a stock std::thread model in c++0x, which was just nailed down and hasn't yet been implemented. The problem is somewhat systemic, technically the existing c++ memory model isn't strict enough to allow for well defined semantics for all of the 'happens before' cases. Hans Boehm wrote an paper on the topic a while back and was instrumental in hammering out the c++0x standard on the topic.

http://www.hpl.hp.com/techreports/2004/HPL-2004-209.html

That said there are several cross-platform thread C++ libraries that work just fine in practice. Intel thread building blocks contains a tbb::thread object that closely approximates the c++0x standard and Boost has a boost::thread library that does the same.

http://www.threadingbuildingblocks.org/

http://www.boost.org/doc/libs/1_37_0/doc/html/thread.html

Using boost::thread you'd get something like:

#include <boost/thread.hpp>

void task1() { 
    // do stuff
}

void task2() { 
    // do stuff
}

int main (int argc, char ** argv) {
    using namespace boost; 
    thread thread_1 = thread(task1);
    thread thread_2 = thread(task2);

    // do other stuff
    thread_2.join();
    thread_1.join();
    return 0;
}

You could use the setTimeout() function:

// Your delay in milliseconds
var delay = 1000; 
setTimeout(function(){ window.location = URL; }, delay);

Assuming the items override ToString appropriately:

public void WriteToConsole(IEnumerable items)
{
    foreach (object o in items)
    {
        Console.WriteLine(o);
    }
}

(There'd be no advantage in using generics in this loop - we'd end up calling Console.WriteLine(object) anyway, so it would still box just as it does in the foreach part in this case.)

EDIT: The answers using List<T>.ForEach are very good.

My loop above is more flexible in the case where you have an arbitrary sequence (e.g. as the result of a LINQ expression), but if you definitely have a List<T> I'd say that List<T>.ForEach is a better option.

One advantage of List<T>.ForEach is that if you have a concrete list type, it will use the most appropriate overload. For example:

List<int> integers = new List<int> { 1, 2, 3 };
List<string> strings = new List<string> { "a", "b", "c" };

integers.ForEach(Console.WriteLine);
strings.ForEach(Console.WriteLine);

When writing out the integers, this will use Console.WriteLine(int), whereas when writing out the strings it will use Console.WriteLine(string). If no specific overload is available (or if you're just using a generic List<T> and the compiler doesn't know what T is) it will use Console.WriteLine(object).

Note the use of Console.WriteLine as a method group, by the way. This is more concise than using a lambda expression, and actually slightly more efficient (as the delegate will just be a call to Console.WriteLine, rather than a call to a method which in turn just calls Console.WriteLine).

Charles Bailey's answer is correct. The exact wording from the C++ standard is (§4.7/4): "If the source type is bool, the value false is converted to zero and the value true is converted to one."

Edit: I see he's added the reference as well -- I'll delete this shortly, if I don't get distracted and forget...

Edit2: Then again, it is probably worth noting that while the Boolean values themselves always convert to zero or one, a number of functions (especially from the C standard library) return values that are "basically Boolean", but represented as ints that are normally only required to be zero to indicate false or non-zero to indicate true. For example, the is* functions in <ctype.h> only require zero or non-zero, not necessarily zero or one.

If you cast that to bool, zero will convert to false, and non-zero to true (as you'd expect).

Is the ??? free to be defined by the user?

Yes.

or is it supplied by the HTML?

No. HTML has nothing to do with that. Read below.

Is it possible for me to define the ??? as abcdefg?

Yes.

If you want to send the following data to the web server:

name = John
age = 12

using application/x-www-form-urlencoded would be like this:

name=John&age=12

As you can see, the server knows that parameters are separated by an ampersand &. If & is required for a parameter value then it must be encoded.

So how does the server know where a parameter value starts and ends when it receives an HTTP request using multipart/form-data?

Using the boundary, similar to &.

For example:

--XXX
Content-Disposition: form-data; name="name"

John
--XXX
Content-Disposition: form-data; name="age"

12
--XXX--

In that case, the boundary value is XXX. You specify it in the Content-Type header so that the server knows how to split the data it receives.

So you need to:

• Use a value that won't appear in the HTTP data sent to the server.

• Be consistent and use the same value everywhere in the request message.

As I understand Copy-Item -Exclude then you are doing it correct. What I usually do, get 1'st, and then do after, so what about using Get-Item as in

Get-Item -Path $copyAdmin -Exclude $exclude |
Copy-Item  -Path $copyAdmin -Destination $AdminPath -Recurse -force

Step1:

sudo gedit ~/.bash_profile

Step2:

JAVA_HOME=/home/user/tool/jdk-8u201-linux-x64/jdk1.8.0_201
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
export JAVA_HOME
export JRE_HOME
export PATH

Step3:

source ~/.bash_profile

In case of Swift Developer coming here,

to convert from NSString / String to NSData

var _nsdata = _nsstring.dataUsingEncoding(NSUTF8StringEncoding)

Since it takes 2 mins to respond, you can increase the timeout to 3 mins by adding the below code

scGetruntotals.CommandTimeout = 180;

Note : the parameter value is in seconds.

make sure your have correct jackson version in your classpath

my_function.__name__

Using __name__ is the preferred method as it applies uniformly. Unlike func_name, it works on built-in functions as well:

>>> import time
>>> time.time.func_name
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AttributeError: 'builtin_function_or_method' object has no attribute 'func_name'
>>> time.time.__name__ 
'time'

Also the double underscores indicate to the reader this is a special attribute. As a bonus, classes and modules have a __name__ attribute too, so you only have remember one special name.

Check the ExcelPackage project, it uses the Office Open XML file format of Excel 2007, it's lightweight and open source...

From grep --help, but also see man grep:

Exit status is 0 if any line was selected, 1 otherwise; if any error occurs and -q was not given, the exit status is 2.

if grep --quiet MYSQL_ROLE=master /etc/aws/hosts.conf; then
  echo exists
else
  echo not found
fi

You may want to use a more specific regex, such as ^MYSQL_ROLE=master$, to avoid that string in comments, names that merely start with "master", etc.

This works because the if takes a command and runs it, and uses the return value of that command to decide how to proceed, with zero meaning true and non-zero meaning false—the same as how other return codes are interpreted by the shell, and the opposite of a language like C.

The pip's proxy parameter is, according to pip --help, in the form scheme://[user:passwd@]proxy.server:port

You should use the following:

pip install --proxy http://user:password@proxyserver:port TwitterApi

Also, the HTTP_PROXY env var should be respected.

Note that in earlier versions (couldn't track down the change in the code, sorry, but the doc was updated here), you had to leave the scheme:// part out for it to work, i.e. pip install --proxy user:password@proxyserver:port

If you are using NativeBase as UI Components you can use this sample

<Item floatingLabel>
    <Label>Title</Label>
    <Input
        returnKeyType = {"next"}
        autoFocus = {true}
        onSubmitEditing={(event) => {
            this._inputDesc._root.focus(); 
        }} />
</Item>
<Item floatingLabel>
    <Label>Description</Label>
    <Input
        getRef={(c) => this._inputDesc = c}
        multiline={true} style={{height: 100}} />
        onSubmitEditing={(event) => { this._inputLink._root.focus(); }} />
</Item>

If you only made changes and deleted a file, but not commit it, and now you broke up with your changes

git checkout -- .

but your deleted files did not return, you simply do the following command:

git checkout <file_path>

And presto, your file is back.

Suppose access a proxy server A(eg. nginx), and the server A forwards the request to another server B(eg. tomcat).

If this process continues for a long time (more than the proxy server read timeout setting), A still did not get a completed response of B. It happens.

for nginx, You can configure the proxy_read_timeout(in location) property to solve his.But this is usually not a good idea, if you set the value too high. This may hide the real error.You'd better improve the design to really solve this problem.

Using Process.Start on explorer.exe with the /select argument oddly only works for paths less than 120 characters long.

I had to use a native windows method to get it to work in all cases:

{
    IntPtr nativeFolder;
    uint psfgaoOut;
    SHParseDisplayName(folderPath, IntPtr.Zero, out nativeFolder, 0, out psfgaoOut);

    if (nativeFolder == IntPtr.Zero)
    {
        // Log error, can't find folder
        return;
    }

    IntPtr nativeFile;
    SHParseDisplayName(Path.Combine(folderPath, file), IntPtr.Zero, out nativeFile, 0, out psfgaoOut);

    IntPtr[] fileArray;
    if (nativeFile == IntPtr.Zero)
    {
        // Open the folder without the file selected if we can't find the file
        fileArray = new IntPtr[0];
    }
    else
    {
        fileArray = new IntPtr[] { nativeFile };
    }

    SHOpenFolderAndSelectItems(nativeFolder, (uint)fileArray.Length, fileArray, 0);

    Marshal.FreeCoTaskMem(nativeFolder);
    if (nativeFile != IntPtr.Zero)
    {
        Marshal.FreeCoTaskMem(nativeFile);
    }
}

Float: left, display: inline-block will both fail to align the elements horizontally if they exceed the width of the container.

It's important to note that the container should not wrap if the elements MUST display horizontally: white-space: nowrap

You should definitely consider using a package like @Shubham above is advising, but I created a working codepen based on what you described: http://codepen.io/dtschust/pen/WGwdVN?editors=1111 .

Anything that is static is in the class level. You don't have to create instance to access static fields/method. Static variable will be created once when class is loaded.

Instance variables are the variable associated with the object which means that instance variables are created for each object you create. All objects will have separate copy of instance variable for themselves.

In your case, when you declared it as static final, that is only one copy of variable. If you change it from multiple instance, the same variable would be updated (however, you have final variable so it cannot be updated).

In second case, the final int a is also constant , however it is created every time you create an instance of the class where that variable is declared.

Have a look on this Java tutorial for better understanding ,

I was face same problem ..... And I got solution by using typeof()

if (typeof(value) !== 'undefined' && value != null) {
         console.log('Not Undefined and Not Null')
  } else {
         console.log('Undefined or Null')
}

You must have to use typeof() to identified undefined

You must add your keyListener to every component that you need. Only the component with the focus will send these events. For instance, if you have only one TextBox in your JFrame, that TextBox has the focus. So you must add a KeyListener to this component as well.

The process is the same:

myComponent.addKeyListener(new KeyListener ...);

Note: Some components aren't focusable like JLabel.

For setting them to focusable you need to:

myComponent.setFocusable(true);

Lucida Console every time.

I've never found a font that can pack as many lines of code onto the screen at the same point size without looking cramped.

And it looks nice too.

With SpringBoot 2 Spring Security, The code below perfectly resolved Cors issues

@Bean
public CorsConfigurationSource corsConfigurationSource() {
    CorsConfiguration configuration = new CorsConfiguration();
    configuration.setAllowedOrigins(Collections.singletonList("*")); // <-- you may change "*"
    configuration.setAllowedMethods(Arrays.asList("HEAD", "GET", "POST", "PUT", "DELETE", "PATCH"));
    configuration.setAllowCredentials(true);
    configuration.setAllowedHeaders(Arrays.asList(
            "Accept", "Origin", "Content-Type", "Depth", "User-Agent", "If-Modified-Since,",
            "Cache-Control", "Authorization", "X-Req", "X-File-Size", "X-Requested-With", "X-File-Name"));
    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    source.registerCorsConfiguration("/**", configuration);
    return source;
}

@Bean
public FilterRegistrationBean<CorsFilter> corsFilterRegistrationBean() {
    FilterRegistrationBean<CorsFilter> bean = new FilterRegistrationBean<>(new CorsFilter(corsConfigurationSource()));
    bean.setOrder(Ordered.HIGHEST_PRECEDENCE);
    return bean;
}

Then for the WebSecurity Configuration, I added this

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.headers().frameOptions().disable()
            .and()
            .authorizeRequests()
            .antMatchers("/oauth/tokeen").permitAll()
            .antMatchers(HttpMethod.GET, "/").permitAll()
            .antMatchers(HttpMethod.POST, "/").permitAll()
            .antMatchers(HttpMethod.PUT, "/").permitAll()
            .antMatchers(HttpMethod.DELETE, "/**").permitAll()
            .antMatchers(HttpMethod.OPTIONS, "*").permitAll()
            .anyRequest().authenticated()
            .and().cors().configurationSource(corsConfigurationSource());
}

I had this info message "No Spring WebApplicationInitializer types detected on classpath" while deploying a WAR with spring integration beans in WebLogic server. Actually, I could observe that the servlet URL returned 404 Not Found and beside that info message with a negative tone "No Spring ...etc" in Server logs, nothing else was seemingly in error in my spring config; no build or deployment errors, no complaints. Indeed, I suspected that the beans.xml (spring context XML) was actually not picked up at all and that was bound to the very specific organizing of artefacts in Oracle's jDeveloper. The solution is to play carefully with the 'contributors' and 'filters' for the WEB-INF/classes category when you edit your deployment profile under the 'deployment' topic in project properties.

Precisely, I would advise to name your spring context by the jDeveloper default "beans.xml" and place it side by side to the WEB-INF subdirectory itself (under your web Apllication source path, e.g. like <...your project path>/public_html/). Then in the WEB-INF/classes category (when editing the deployment profile) your can check the Project HTML root directory in the 'contributor' list, and then select the beans.xml in filters, and then ensure your web.xml features a context-param value like classpath:beans.xml.

Once that was fixed, I was able to progress and after some more bean config changes and implementations, the message "No Spring WebApplicationInitializer types detected on classpath" came back! Actually, I did not notice when and why exactly it came back. This second time, I added a

public class HttpGatewayInit implements WebApplicationInitializer { ... }

which implements empty inherited methods, and the whole application works fine!

...If you feel that java EE development has been getting a bit too crazy with cascades of XML configuration files (some edited manually, others through wizards) intepreted by cascades of variant initializers, let me insist that I fully share your point.

Insert date in the following format yyyy-MM-dd example,

INSERT INTO `PROGETTO`.`ALBERGO`(`ID`, `nome`, `viale`, `num_civico`, `data_apertura`, `data_chiusura`, `orario_apertura`, `orario_chiusura`, `posti_liberi`, `costo_intero`, `costo_ridotto`, `stelle`, `telefono`, `mail`, `web`, `Nome-paese`, `Comune`) 
VALUES(0, 'Hotel Centrale', 'Via Passo Rolle', '74', '2012-05-01', '2012-09-31', '06:30', '24:00', 80, 50, 25, 3, '43968083', '[email protected]', 'http://www.hcentrale.it/', 'Trento', 'TN')

You can also do it this way without the need of Linq:

List<int> numbers = new List<int>( Array.ConvertAll(sNumbers.Split(','), int.Parse) );

// Uses Linq
var numbers = Array.ConvertAll(sNumbers.Split(','), int.Parse).ToList();

"When to use setAttribute vs .attribute= in JavaScript?"

A general rule is to use .attribute and check if it works on the browser.

..If it works on the browser, you're good to go.

..If it doesn't, use .setAttribute(attribute, value) instead of .attribute for that attribute.

Rinse-repeat for all attributes.

Well, if you're lazy you can simply use .setAttribute. That should work fine on most browsers. (Though browsers that support .attribute can optimize it better than .setAttribute(attribute, value).)

It's already been answered a few times, but Python is a strongly typed language:

>>> x = 3
>>> y = '4'
>>> print(x+y)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for +: 'int' and 'str'

The following in JavaScript:

var x = 3    
var y = '4'
alert(x + y) //Produces "34"

That's the difference between weak typing and strong typing. Weak types automatically try to convert from one type to another, depending on context (e.g. Perl). Strong types never convert implicitly.

Your confusion lies in a misunderstanding of how Python binds values to names (commonly referred to as variables).

In Python, names have no types, so you can do things like:

bob = 1
bob = "bob"
bob = "An Ex-Parrot!"

And names can be bound to anything:

>>> def spam():
...     print("Spam, spam, spam, spam")
...
>>> spam_on_eggs = spam
>>> spam_on_eggs()
Spam, spam, spam, spam

There are many ways to get a path. See CurrentDirrectory mentioned. Also, you can get the full file name of your application by using Assembly.GetExecutingAssembly().Location and then use Path class to get a directory name.

No need to hack settings. There is a simple way:

print(df.to_string())

I had a similar problem and none of the solutions above worked, so I went with an old standby that always works:

1. Rename the folder containing the project
2. Make a brand new project with the same name with 2010
3. Diff the two folders and->
4. Copy all source files directly
5. Ignore bin/debug/release etc
6. Diff the .csproj and copy over all lines that are relevant.
7. If the .sln file only has one project, ignore it. If it's complex, then diff it as well.

That almost always works if you've spent 10 minutes at it and can't get it.

Note that for similar problems with older versions (2008, 2005) you can usually get away with just changing the version in the .csproj and either changing the version in the .sln or discarding it, but this doesn't seem to work for 2013.

In my opinion the top answers are not readable/maintainable, and the other answers do not properly bind context. Here's a readable solution using ES6 syntax to solve both these problems.

const orginial = someObject.foo;
someObject.foo = function() {
  if (condition) orginial.bind(this)(...arguments);
};

This enables you to write something like:

void doSomething() {
    List<String>list = new ArrayList<String>();
    //do something
}

Later on, you might want to change it to:

void doSomething() {
    List<String>list = new LinkedList<String>();
    //do something
}

without having to change the rest of the method.

However, if you want to use a CopyOnWriteArrayList for example, you would need to declare it as such, and not as a List if you wanted to use its extra methods (addIfAbsent for example):

void doSomething() {
    CopyOnWriteArrayList<String>list = new CopyOnWriteArrayList<String>();
    //do something, for example:
    list.addIfAbsent("abc");
}

I feel

var x = request.post({
       uri: config.uri,
       json: reqData
    });

Defining like this will be the effective way of writing your code. And application/json should be automatically added. There is no need to specifically declare it.

Edit your httpd.conf file as follows:

# nano /etc/httpd/conf/httpd.conf

Add the following lines here:

<Directory "/usr/share/phpmyadmin">
    Order allow,deny
    Allow from all
</Directory>

Issue the following command:

# service httpd restart

If your problem is not solved then disable your SELinux.

using (SqlConnection connection =  new SqlConnection("Data Source=localhost;Initial Catalog=LoginScreen;Integrated Security=True"))
{
    SqlCommand command =
    new SqlCommand("select * from Pending_Tasks WHERE CustomerId=...", connection);
    connection.Open();

    SqlDataReader read= command.ExecuteReader();

    while (read.Read())
    {
        CustID.Text = (read["Customer_ID"].ToString());
        CustName.Text = (read["Customer_Name"].ToString());
        Add1.Text = (read["Address_1"].ToString());
        Add2.Text = (read["Address_2"].ToString());
        PostBox.Text = (read["Postcode"].ToString());
        PassBox.Text = (read["Password"].ToString());
        DatBox.Text = (read["Data_Important"].ToString());
        LanNumb.Text = (read["Landline"].ToString());
        MobNumber.Text = (read["Mobile"].ToString());
        FaultRep.Text = (read["Fault_Report"].ToString());
    }
    read.Close();
}

Make sure you have data in the query : select * from Pending_Tasks and you are using "using System.Data.SqlClient;"

You will need to melt your dataframe to get it into the so-called long format:

require(reshape2)
sample.data.M <- melt(sample.data)

Now your field values are represented by their own rows and identified through the variable column. This can now be leveraged within the ggplot aesthetics:

require(ggplot2)
c <- ggplot(sample.data.M, aes(x = Rank, y = value, fill = variable))
c + geom_bar(stat = "identity")

Instead of stacking you may also be interested in showing multiple plots using facets:

c <- ggplot(sample.data.M, aes(x = Rank, y = value))
c + facet_wrap(~ variable) + geom_bar(stat = "identity")

I realize this is an old thread, but @alex 's answer needs to be marked as the correct answer

element.getBoundingClientRect() is an exact match to jQuery's $(element).offset()

How is this usually done? Should I copy the cmake/ directory of SomeLib into my project and set the CMAKE_MODULE_PATH relatively?

If you don't trust CMake to have that module, then - yes, do that - sort of: Copy the find_SomeLib.cmake and its dependencies into your cmake/ directory. That's what I do as a fallback. It's an ugly solution though.

Note that the FindFoo.cmake modules are each a sort of a bridge between platform-dependence and platform-independence - they look in various platform-specific places to obtain paths in variables whose names is platform-independent.

Neither malloc or call by reference are needed. You can declare a pointer within the function and set it to the string/array you'd like to return.

Using @Gewure's code as the basis:

char *getStringNoMalloc(void){
    char string[100] = {};
    char *s_ptr = string;

    strcat(string, "bla");
    strcat(string, "/");
    strcat(string, "blub");
    //INSIDE this function "string" is OK
    printf("string : '%s'\n", string);

    return s_ptr; 
}

works perfectly.

With a non-loop version of the code in the original question:

char *foo(int x){    
    char a[1000];
    char *a_ptr = a;
    char *b = "blah";       

    strcpy(a, b);

    return a_ptr;
}

I use Singletons as an interview test.

When I ask a developer to name some design patterns, if all they can name is Singleton, they're not hired.

Try:

git config core.fileMode false

From git-config(1):

core.fileMode
    Tells Git if the executable bit of files in the working tree
    is to be honored.

    Some filesystems lose the executable bit when a file that is
    marked as executable is checked out, or checks out a
    non-executable file with executable bit on. git-clone(1)
    or git-init(1) probe the filesystem to see if it handles the 
    executable bit correctly and this variable is automatically
    set as necessary.

    A repository, however, may be on a filesystem that handles
    the filemode correctly, and this variable is set to true when
    created, but later may be made accessible from another
    environment that loses the filemode (e.g. exporting ext4
    via CIFS mount, visiting a Cygwin created repository with Git
    for Windows or Eclipse). In such a case it may be necessary
    to set this variable to false. See git-update-index(1).

    The default is true (when core.filemode is not specified
    in the config file).

The -c flag can be used to set this option for one-off commands:

git -c core.fileMode=false diff

And the --global flag will make it be the default behavior for the logged in user.

git config --global core.fileMode false

Changes of the global setting won't be applied to existing repositories. Additionally, git clone and git init explicitly set core.fileMode to true in the repo config as discussed in Git global core.fileMode false overridden locally on clone

Warning

core.fileMode is not the best practice and should be used carefully. This setting only covers the executable bit of mode and never the read/write bits. In many cases you think you need this setting because you did something like chmod -R 777, making all your files executable. But in most projects most files don't need and should not be executable for security reasons.

The proper way to solve this kind of situation is to handle folder and file permission separately, with something like:

find . -type d -exec chmod a+rwx {} \; # Make folders traversable and read/write
find . -type f -exec chmod a+rw {} \;  # Make files read/write

If you do that, you'll never need to use core.fileMode, except in very rare environment.

Old post, but I'd say the cleanest approach would be to add a class to the surrounding div and a button class on each button so your CSS rule becomes useful for more use cases:

/* Added to highlight spacing */_x000D_
.is-grouped {   _x000D_
    display: inline-block;_x000D_
    background-color: yellow;_x000D_
}_x000D_
_x000D_
.is-grouped > .button:not(:last-child) {_x000D_
    margin-right: 10px;_x000D_
}

Spacing shown in yellow<br><br>_x000D_
_x000D_
<div class='is-grouped'>_x000D_
    <button class='button'>Save</button>_x000D_
    <button class='button'>Save As...</button>_x000D_
    <button class='button'>Delete</button>_x000D_
</div>

You can wrap input stream with PushbackInputStream. PushbackInputStream allows to unread ("write back") bytes which were already read, so you can do like this:

public class StreamTest {
  public static void main(String[] args) throws IOException {
    byte[] bytes = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8, 9 };

    InputStream originalStream = new ByteArrayInputStream(bytes);

    byte[] readBytes = getBytes(originalStream, 3);
    printBytes(readBytes); // prints: 1 2 3

    readBytes = getBytes(originalStream, 3);
    printBytes(readBytes); // prints: 4 5 6

    // now let's wrap it with PushBackInputStream

    originalStream = new ByteArrayInputStream(bytes);

    InputStream wrappedStream = new PushbackInputStream(originalStream, 10); // 10 means that maximnum 10 characters can be "written back" to the stream

    readBytes = getBytes(wrappedStream, 3);
    printBytes(readBytes); // prints 1 2 3

    ((PushbackInputStream) wrappedStream).unread(readBytes, 0, readBytes.length);

    readBytes = getBytes(wrappedStream, 3);
    printBytes(readBytes); // prints 1 2 3


  }

  private static byte[] getBytes(InputStream is, int howManyBytes) throws IOException {
    System.out.print("Reading stream: ");

    byte[] buf = new byte[howManyBytes];

    int next = 0;
    for (int i = 0; i < howManyBytes; i++) {
      next = is.read();
      if (next > 0) {
        buf[i] = (byte) next;
      }
    }
    return buf;
  }

  private static void printBytes(byte[] buffer) throws IOException {
    System.out.print("Reading stream: ");

    for (int i = 0; i < buffer.length; i++) {
      System.out.print(buffer[i] + " ");
    }
    System.out.println();
  }


}

Please note that PushbackInputStream stores internal buffer of bytes so it really creates a buffer in memory which holds bytes "written back".

Knowing this approach we can go further and combine it with FilterInputStream. FilterInputStream stores original input stream as a delegate. This allows to create new class definition which allows to "unread" original data automatically. The definition of this class is following:

public class TryReadInputStream extends FilterInputStream {
  private final int maxPushbackBufferSize;

  /**
  * Creates a <code>FilterInputStream</code>
  * by assigning the  argument <code>in</code>
  * to the field <code>this.in</code> so as
  * to remember it for later use.
  *
  * @param in the underlying input stream, or <code>null</code> if
  *           this instance is to be created without an underlying stream.
  */
  public TryReadInputStream(InputStream in, int maxPushbackBufferSize) {
    super(new PushbackInputStream(in, maxPushbackBufferSize));
    this.maxPushbackBufferSize = maxPushbackBufferSize;
  }

  /**
   * Reads from input stream the <code>length</code> of bytes to given buffer. The read bytes are still avilable
   * in the stream
   *
   * @param buffer the destination buffer to which read the data
   * @param offset  the start offset in the destination <code>buffer</code>
   * @aram length how many bytes to read from the stream to buff. Length needs to be less than
   *        <code>maxPushbackBufferSize</code> or IOException will be thrown
   *
   * @return number of bytes read
   * @throws java.io.IOException in case length is
   */
  public int tryRead(byte[] buffer, int offset, int length) throws IOException {
    validateMaxLength(length);

    // NOTE: below reading byte by byte instead of "int bytesRead = is.read(firstBytes, 0, maxBytesOfResponseToLog);"
    // because read() guarantees to read a byte

    int bytesRead = 0;

    int nextByte = 0;

    for (int i = 0; (i < length) && (nextByte >= 0); i++) {
      nextByte = read();
      if (nextByte >= 0) {
        buffer[offset + bytesRead++] = (byte) nextByte;
      }
    }

    if (bytesRead > 0) {
      ((PushbackInputStream) in).unread(buffer, offset, bytesRead);
    }

    return bytesRead;

  }

  public byte[] tryRead(int maxBytesToRead) throws IOException {
    validateMaxLength(maxBytesToRead);

    ByteArrayOutputStream baos = new ByteArrayOutputStream(); // as ByteArrayOutputStream to dynamically allocate internal bytes array instead of allocating possibly large buffer (if maxBytesToRead is large)

    // NOTE: below reading byte by byte instead of "int bytesRead = is.read(firstBytes, 0, maxBytesOfResponseToLog);"
    // because read() guarantees to read a byte

    int nextByte = 0;

    for (int i = 0; (i < maxBytesToRead) && (nextByte >= 0); i++) {
      nextByte = read();
      if (nextByte >= 0) {
        baos.write((byte) nextByte);
      }
    }

    byte[] buffer = baos.toByteArray();

    if (buffer.length > 0) {
      ((PushbackInputStream) in).unread(buffer, 0, buffer.length);
    }

    return buffer;

  }

  private void validateMaxLength(int length) throws IOException {
    if (length > maxPushbackBufferSize) {
      throw new IOException(
        "Trying to read more bytes than maxBytesToRead. Max bytes: " + maxPushbackBufferSize + ". Trying to read: " +
        length);
    }
  }

}

This class has two methods. One for reading into existing buffer (defintion is analogous to calling public int read(byte b[], int off, int len) of InputStream class). Second which returns new buffer (this may be more effective if the size of buffer to read is unknown).

Now let's see our class in action:

public class StreamTest2 {
  public static void main(String[] args) throws IOException {
    byte[] bytes = new byte[] { 1, 2, 3, 4, 5, 6, 7, 8, 9 };

    InputStream originalStream = new ByteArrayInputStream(bytes);

    byte[] readBytes = getBytes(originalStream, 3);
    printBytes(readBytes); // prints: 1 2 3

    readBytes = getBytes(originalStream, 3);
    printBytes(readBytes); // prints: 4 5 6

    // now let's use our TryReadInputStream

    originalStream = new ByteArrayInputStream(bytes);

    InputStream wrappedStream = new TryReadInputStream(originalStream, 10);

    readBytes = ((TryReadInputStream) wrappedStream).tryRead(3); // NOTE: no manual call to "unread"(!) because TryReadInputStream handles this internally
    printBytes(readBytes); // prints 1 2 3

    readBytes = ((TryReadInputStream) wrappedStream).tryRead(3); 
    printBytes(readBytes); // prints 1 2 3

    readBytes = ((TryReadInputStream) wrappedStream).tryRead(3);
    printBytes(readBytes); // prints 1 2 3

    // we can also call normal read which will actually read the bytes without "writing them back"
    readBytes = getBytes(wrappedStream, 3);
    printBytes(readBytes); // prints 1 2 3

    readBytes = getBytes(wrappedStream, 3);
    printBytes(readBytes); // prints 4 5 6

    readBytes = ((TryReadInputStream) wrappedStream).tryRead(3); // now we can try read next bytes
    printBytes(readBytes); // prints 7 8 9

    readBytes = ((TryReadInputStream) wrappedStream).tryRead(3); 
    printBytes(readBytes); // prints 7 8 9


  }

the warning or error of kind IMPLICIT DECLARATION is that the compiler is expecting a Function Declaration/Prototype..

It might either be a header file or your own function Declaration..

It is a viable way to use std::vector as an intermediate container:

I know, the question is asked three years ago, and my answer is another version of what Tim has posted, But posting just incase it is helpful for anyone.

mootools example:

var ret = JSON.decode(jsonstr);

ret.each(function(item){
    alert(item.id+'_'+item.classd);
});

Following on from LES2's answer, you can eliminate some repetition in the efficient version, by calling the overloaded function:

public static <T> T coalesce(T a, T b) {
    return a != null ? a : b;
}
public static <T> T coalesce(T a, T b, T c) {
    return a != null ? a : coalesce(b,c);
}
public static <T> T coalesce(T a, T b, T c, T d) {
    return a != null ? a : coalesce(b,c,d);
}
public static <T> T coalesce(T a, T b, T c, T d, T e) {
    return a != null ? a : coalesce(b,c,d,e);
}

You should define source code encoding, add this to the top of your script:

# -*- coding: utf-8 -*-

The reason why it works differently in console and in the IDE is, likely, because of different default encodings set. You can check it by running:

import sys
print sys.getdefaultencoding()

    *word-spacing: normal !important;
}
.slabtextdone .slabtext
{
    display: block;
}

And the script:

$('#mydiv').slabText();

From the jQuery.each() documentation:

.each( function(index, Element) )
    function(index, Element)A function to execute for each matched element.

So you'll want to use:

$('#list option').each(function(i,e){
    //do stuff
});

...where index will be the index and element will be the option element in list

The DBHelper class is what handles the opening and closing of sqlite databases as well sa creation and updating, and a decent article on how it all works is here. When I started android it was very useful (however I've been objective-c lately, and forgotten most of it to be any use.

I would recommend the read_csv function from the pandas library:

import pandas as pd
df=pd.read_csv('myfile.csv', sep=',',header=None)
df.values
array([[ 1. ,  2. ,  3. ],
       [ 4. ,  5.5,  6. ]])

This gives a pandas DataFrame - allowing many useful data manipulation functions which are not directly available with numpy record arrays.

DataFrame is a 2-dimensional labeled data structure with columns of potentially different types. You can think of it like a spreadsheet or SQL table...

I would also recommend genfromtxt. However, since the question asks for a record array, as opposed to a normal array, the dtype=None parameter needs to be added to the genfromtxt call:

Given an input file, myfile.csv:

1.0, 2, 3
4, 5.5, 6

import numpy as np
np.genfromtxt('myfile.csv',delimiter=',')

gives an array:

array([[ 1. ,  2. ,  3. ],
       [ 4. ,  5.5,  6. ]])

and

np.genfromtxt('myfile.csv',delimiter=',',dtype=None)

gives a record array:

array([(1.0, 2.0, 3), (4.0, 5.5, 6)], 
      dtype=[('f0', '<f8'), ('f1', '<f8'), ('f2', '<i4')])

This has the advantage that file with multiple data types (including strings) can be easily imported.

PyQt4 can be forced to use a new API in which QString is automatically converted to and from a Python object:

import sip
sip.setapi('QString', 2)

With this API, QtCore.QString class is no longer available and self.ui.comboBox.currentText() will return a Python string or unicode object.

See Selecting Incompatible APIs from the doc.

if (dr[dc.ColumnName].GetType().ToString() == "System.DateTime")

As an illustration

import fs from 'fs';
import http from 'http';

const options = {
  host: 'www.stackoverflow.com',
  port: 80,
  path: '/index.html'
};

describe('deferredExecution', () => {
  it('deferredExecution', (done) => {
    console.log('Start');
    setTimeout(() => console.log('TO1'), 0);
    setImmediate(() => console.log('IM1'));
    process.nextTick(() => console.log('NT1'));
    setImmediate(() => console.log('IM2'));
    process.nextTick(() => console.log('NT2'));
    http.get(options, () => console.log('IO1'));
    fs.readdir(process.cwd(), () => console.log('IO2'));
    setImmediate(() => console.log('IM3'));
    process.nextTick(() => console.log('NT3'));
    setImmediate(() => console.log('IM4'));
    fs.readdir(process.cwd(), () => console.log('IO3'));
    console.log('Done');
    setTimeout(done, 1500);
  });
});

will give the following output

Start
Done
NT1
NT2
NT3
TO1
IO2
IO3
IM1
IM2
IM3
IM4
IO1

I hope this can help to understand the difference.

Updated:

Callbacks deferred with process.nextTick() run before any other I/O event is fired, while with setImmediate(), the execution is queued behind any I/O event that is already in the queue.

Node.js Design Patterns, by Mario Casciaro (probably the best book about node.js/js)

Great Explanation from the link : http://geekswithblogs.net/dlussier/archive/2009/11/21/136454.aspx

Let's First look at MVC

The input is directed at the Controller first, not the view. That input might be coming from a user interacting with a page, but it could also be from simply entering a specific url into a browser. In either case, its a Controller that is interfaced with to kick off some functionality.

There is a many-to-one relationship between the Controller and the View. That’s because a single controller may select different views to be rendered based on the operation being executed.

There is one way arrow from Controller to View. This is because the View doesn’t have any knowledge of or reference to the controller.

The Controller does pass back the Model, so there is knowledge between the View and the expected Model being passed into it, but not the Controller serving it up.

MVP – Model View Presenter

Now let’s look at the MVP pattern. It looks very similar to MVC, except for some key distinctions:

The input begins with the View, not the Presenter.

There is a one-to-one mapping between the View and the associated Presenter.

The View holds a reference to the Presenter. The Presenter is also reacting to events being triggered from the View, so its aware of the View its associated with.

The Presenter updates the View based on the requested actions it performs on the Model, but the View is not Model aware.

MVVM – Model View View Model

So with the MVC and MVP patterns in front of us, let’s look at the MVVM pattern and see what differences it holds:

The input begins with the View, not the View Model.

While the View holds a reference to the View Model, the View Model has no information about the View. This is why its possible to have a one-to-many mapping between various Views and one View Model…even across technologies. For example, a WPF View and a Silverlight View could share the same View Model.

I think that the best solution would be to use JavaScript.

But I'm not sure that you need to do this to solve your problem of positioning elements in the <td> outside of the cell. For that you could do something like this:

<div style="position:relative">
    <table>
        <tr>
            <td>
                <div style="position:absolute;bottom:-100px">hello world</div>
            </td>
        </tr>
    </table>
</div>

Not inline of course, but with classes and ids.

If you actually have set a root password and you've just lost/forgotten it:

1. Stop MySQL

2. Restart it manually with the skip-grant-tables option: mysqld_safe --skip-grant-tables

3. Now, open a new terminal window and run the MySQL client: mysql -u root

4. Reset the root password manually with this MySQL command: UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root'; If you are using MySQL 5.7 (check using mysql --version in the Terminal) then the command is:

   UPDATE mysql.user SET authentication_string=PASSWORD('password')  WHERE  User='root';
   

5. Flush the privileges with this MySQL command: FLUSH PRIVILEGES;

From http://www.tech-faq.com/reset-mysql-password.shtml

(Maybe this isn't what you need, Abs, but I figure it could be useful for people stumbling across this question in the future)

To remove the tracked and old committed file from git you can use the below command. Here in my case, I want to untrack and remove all the file from dist directory.

git filter-branch --force --index-filter 'git rm -r --cached --ignore-unmatch dist' --tag-name-filter cat -- --all

Then, you need to add it into your .gitignore so it won't be tracked further.

You can use a session object. It stores the cookies so you can make requests, and it handles the cookies for you

s = requests.Session() 
# all cookies received will be stored in the session object

s.post('http://www...',data=payload)
s.get('http://www...')

Docs: https://requests.readthedocs.io/en/master/user/advanced/#session-objects

You can also save the cookie data to an external file, and then reload them to keep session persistent without having to login every time you run the script:

How to save requests (python) cookies to a file?

I have a background service that performs an action for each entry in a table. The problem is, that if I iterate over and modify some data all on the same instance of the DbContext this error occurs.

One solution, as mentioned in this thread is to change the DbContext's lifetime to transient by defining it like

services.AddDbContext<DbContext>(ServiceLifetime.Transient);

but because I do changes in multiple different services and commit them at once using the SaveChanges() method this solution doesnt work in my case.

Because my code runs in a service, I was doing something like

using (var scope = Services.CreateScope())
{
   var entities = scope.ServiceProvider.GetRequiredService<IReadService>().GetEntities();
   var writeService = scope.ServiceProvider.GetRequiredService<IWriteService>();
   foreach (Entity entity in entities)
   {
       writeService.DoSomething(entity);
   } 
}

to be able to use the service like if it was a simple request. So to solve the issue i just split the single scope into two, one for the query and the other for the write operations like so:

using (var readScope = Services.CreateScope())
using (var writeScope = Services.CreateScope())
{
   var entities = readScope.ServiceProvider.GetRequiredService<IReadService>().GetEntities();
   var writeService = writeScope.ServiceProvider.GetRequiredService<IWriteService>();
   foreach (Entity entity in entities)
   {
       writeService.DoSomething(entity);
   } 
}

Like that, there are effevtively two different instances of the DbContext being used.

Another possible solution would be to make sure, that the read operation has terminated before starting the iteration. That is not very pratical in my case because there could be a lot of results that would all need to be loaded into memory for the operation which I tried to avoid by using a Queryable in the first place.

cout is in std namespace, you shall use std::cout in your code. And you shall not add using namespace std; in your header file, it's bad to mix your code with std namespace, especially don't add it in header file.

clean package exec:java -P Class_Containing_Main_Method command is also an option if you have only one Main method(PSVM) in the project, with the following Maven Setup.

Don't forget to mention the class in the <properties></properties> section of pom.xml :

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <java.main.class>com.test.service.MainTester</java.main.class>
</properties>

<plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>exec-maven-plugin</artifactId>
        <version>1.2.1</version>
        <configuration>
           <mainClass>${java.main.class}</mainClass>
        </configuration>
</plugin>

STS Run Configuration along with above Maven Setup:

If you installed it on port 8080, you need to access it on port 8080:

http://localhost:8080 or http://127.0.0.1:8080

Basically, Undefined is a global variable that javascript create at the run time whether null means that no value has assigned to the variable (actually null is itself an object).

Let's take an example:

        var x;  //we declared a variable x, but no value has been assigned to it.
        document.write(x) //let's print the variable x

Undefined that's what you will get as output.

Now,

        x=5;
        y=null;
        z=x+y;

and you will get 5 as output. That's the main difference between the Undefined and null

I found this question as I was researching an error after I upgraded from 1.7.2 of jQuery to 1.8.2. I'm adding my answer because there has been a change in jQuery 1.8 and higher that changes how this question is answered now.

With jQuery 1.8 they have deprecated the pseudo-selectors like :radio, :checkbox, :text.

To do the above now just replace the :radio with [type=radio].

So your answer now becomes for all versions of jQuery 1.8 and above:

$("input[type=radio][name=theme]").click(function() { 
    var value = $(this).val(); 
}); 

You can read about the change on the 1.8 readme and the ticket specific for this change as well as a understand why on the :radio selector page under the Additional Information section.

Try out this will solve ur problem ....

EditText etxt = (EditText)findviewbyid(R.id.etxt);
String str_value = etxt.getText().toString();

For those use Msys/MinGW GIT, add this

  export GIT_SSL_CAINFO=/mingw32/ssl/certs/ca-bundle.crt 

you can also use this format and use comparison operators like '==' '<='

  if (( $total == 0 )); then
      echo "No results for ${1}"
      return
  fi

This is actually on the main page of nltk.org:

>>> import nltk
>>> sentence = """At eight o'clock on Thursday morning
... Arthur didn't feel very good."""
>>> tokens = nltk.word_tokenize(sentence)
>>> tokens
['At', 'eight', "o'clock", 'on', 'Thursday', 'morning',
'Arthur', 'did', "n't", 'feel', 'very', 'good', '.']

As far as I have understood your question, you have listed two issues.

PROBLEM 1:

You are not able to execute the Python scripts by double clicking the Python file in Windows.

REASON:

The script runs too fast to be seen by the human eye.

SOLUTION:

Add input() in the bottom of your script and then try executing it with double click. Now the cmd will be open until you close it.

EXAMPLE:

print("Hello World")
input()

PROBLEM 2:

./ issue

SOLUTION:

Use Tab to autocomplete the filenames rather than manually typing the filename with ./ autocomplete automatically fills all this for you.

USAGE:

CD into the directory in which .py files are present and then assume the filename is test.py then type python te and then press Tab, it will be automatically converted to python ./test.py.

You want something like:

<appSettings>
  <add key="developmentModeUserId" xdt:Transform="Remove" xdt:Locator="Match(key)"/>
  <add key="developmentMode" value="false" xdt:Transform="SetAttributes"
          xdt:Locator="Match(key)"/>
</appSettings>

In Visual Studio, you can't just open a .cpp file and expect it to run. You must create a project first, or open the .cpp in some existing project.

In your case, there is no project, so there is no project to build.

Go to File --> New --> Project --> Visual C++ --> Win32 Console Application. You can uncheck "create a directory for solution". On the next page, be sure to check "Empty project".

Then, You can add .cpp files you created outside the Visual Studio by right clicking in the Solution explorer on folder icon "Source" and Add->Existing Item.

Obviously You can create new .cpp this way too (Add --> New). The .cpp file will be created in your project directory.

Then you can press ctrl+F5 to compile without debugging and can see output on console window.

This will delete all content from current line to end of the file. This is very useful when you're dealing with test vector generation or stripping.

Also you don't have to use setTimeout in this case just make ready function asynchronous...

Extending your PATH with:

export PATH=/usr/local/share/npm/bin:$PATH

isn't a terrible idea. Having said that, you shouldn't have to do it.

Run this:

npm config get prefix

The default on OS X is /usr/local, which means that npm will symlink binaries into /usr/local/bin, which should already be on your PATH (especially if you're using Homebrew).

So:

1. npm config set prefix /usr/local if it's something else, and
2. Don't use sudo with npm! According to the jslint docs, you should just be able to npm install it.

If you installed npm as sudo (sudo brew install), try reinstalling it with plain ol' brew install. Homebrew is supposed to help keep you sudo-free.

On some OS you get . .. and .DS_Store, Well we can't use them so let's us hide them.

First start get all information about the files, using scandir()

// Folder where you want to get all files names from
$dir = "uploads/";

/* Hide this */
$hideName = array('.','..','.DS_Store');    

// Sort in ascending order - this is default
$files = scandir($dir);
/* While this to there no more files are */
foreach($files as $filename) {
    if(!in_array($filename, $hideName)){
       /* echo the name of the files */
       echo "$filename<br>";
    }
}

There are several ways to do a cross join or cartesian product:

SELECT column_names FROM table1 CROSS JOIN table2;

SELECT column_names FROM table1, table2;

SELECT column_names FROM table1 JOIN table2;

Neglecting the on condition in the third case is what results in a cross join.

EDIT: Although, this solution works, I would recommend you try MvanGeest's solution below which uses the placeholder-attribute and a javascript fallback for browsers which don't support it yet.

If you are looking for a Mootools equivalent to the JQuery fallback in MvanGeest's reply, here is one.

You should probably use onfocus and onblur events in order to support keyboard users who tab through forms.

Here's an example:

<input type="text" value="[email protected]" name="Email" id="Email"
 onblur="if (this.value == '') {this.value = '[email protected]';}"
 onfocus="if (this.value == '[email protected]') {this.value = '';}" />

I just had a similar issue, but it didn't error immediately, so it may have not been the same issue.

I'm behind a firewall and changed my proxy settings (TortoiseSVN->Settings->Network) to access an open source repo yesterday. I received the error this morning trying to checkout a repo in the local domain behind the firewall. I just had to remove the proxy settting in TortoiseSVN->Settings->Network to get it work locally again.

I create now the log-css.js https://codepen.io/luis7lobo9b/pen/QWyobwY

// log-css.js v1
