My issue was my SVN permissions.

I had the same problem "Access to '/svn/[my path]/!svn/me' forbidden" when trying to commit files to a project I had been working on daily for several months. After trying the steps above, I could not resolve the issue. I also tried pulling the project down from scratch, logging in/out of SVN, etc. Finally I contacted my company's IT department and there was a permissions issue that spontaneously emerged which changed my access from read/write to read-only access. The IT department refreshed my permissions and this solved the problem.

I have experienced the same issues as you described. It appears to be a bug on Tortoise 1.7.3. I have reverted back to 1.7.2, executed a cleanup and an update. Now my SVN/Tortoise is working fine again

Many ways

pipe your input

echo "yes
no
maybe" | your_program

redirect from a file

your_program < answers.txt

use a here document (this can be very readable)

your_program << ANSWERS
yes
no
maybe
ANSWERS

use a here string

your_program <<< $'yes\nno\nmaybe\n'

When You want to open new tab/window (depends on Your browser configuration defaults):

output = 'Hello, World!';
window.open().document.write(output);

When output is an Object and You want get JSON, for example (also can generate any type of document, even image encoded in Base64)

output = ({a:1,b:'2'});
window.open('data:application/json;' + (window.btoa?'base64,'+btoa(JSON.stringify(output)):JSON.stringify(output)));

Update

Google Chrome (60.0.3112.90) block this code:

Not allowed to navigate top frame to data URL: data:application/json;base64,eyJhIjoxLCJiIjoiMiJ9

When You want to append some data to existing page

output = '<h1>Hello, World!</h1>';
window.open('output.html').document.body.innerHTML += output;

output = 'Hello, World!';
window.open('about:blank').document.body.innerText += output;

There are two ways to achieve that:

• Use -rpath linker option:

gcc XXX.c -o xxx.out -L$HOME/.usr/lib -lXX -Wl,-rpath=/home/user/.usr/lib

• Use LD_LIBRARY_PATH environment variable - put this line in your ~/.bashrc file:

  export LD_LIBRARY_PATH=/home/user/.usr/lib

This will work even for a pre-generated binaries, so you can for example download some packages from the debian.org, unpack the binaries and shared libraries into your home directory, and launch them without recompiling.

For a quick test, you can also do (in bash at least):

LD_LIBRARY_PATH=/home/user/.usr/lib ./xxx.out

which has the advantage of not changing your library path for everything else.

I'm using this method -> based on API Demos to get my Preview Size:

private Camera.Size getOptimalPreviewSize(List<Camera.Size> sizes, int w, int h) {
        final double ASPECT_TOLERANCE = 0.1;
        double targetRatio=(double)h / w;

        if (sizes == null) return null;

        Camera.Size optimalSize = null;
        double minDiff = Double.MAX_VALUE;

        int targetHeight = h;

        for (Camera.Size size : sizes) {
            double ratio = (double) size.width / size.height;
            if (Math.abs(ratio - targetRatio) > ASPECT_TOLERANCE) continue;
            if (Math.abs(size.height - targetHeight) < minDiff) {
                optimalSize = size;
                minDiff = Math.abs(size.height - targetHeight);
            }
        }

        if (optimalSize == null) {
            minDiff = Double.MAX_VALUE;
            for (Camera.Size size : sizes) {
                if (Math.abs(size.height - targetHeight) < minDiff) {
                    optimalSize = size;
                    minDiff = Math.abs(size.height - targetHeight);
                }
            }
        }
        return optimalSize;
    }

As you can see you have to input width and height of your screen. This method will calculate screen ratio based on those values and then from the list of supportedPreviewSizes it will choose the best for you from avaliable ones. Get your supportedPreviewSize list in place where Camera object isn't null by using

mSupportedPreviewSizes = mCamera.getParameters().getSupportedPreviewSizes();

And then on in onMeasure you can get your optimal previewSize like that:

@Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        final int width = resolveSize(getSuggestedMinimumWidth(), widthMeasureSpec);
        final int height = resolveSize(getSuggestedMinimumHeight(), heightMeasureSpec);
        setMeasuredDimension(width, height);

        if (mSupportedPreviewSizes != null) {
           mPreviewSize = getOptimalPreviewSize(mSupportedPreviewSizes, width, height);
        }
    }

And then (in my code in surfaceChanged method, like I said I'm using API Demos structure of CameraActivity code, you can generate it in Eclipse):

Camera.Parameters parameters = mCamera.getParameters();
parameters.setPreviewSize(mPreviewSize.width, mPreviewSize.height);
mCamera.setParameters(parameters);
mCamera.startPreview();

And one hint for you, because I did almost the same app like you. Good practice for Camera Activity is to hide StatusBar. Applications like Instagram are doing it. It reduces your screen height value and change your ratio value. It is possible to get strange Preview Sizes on some devices (your SurfaceView will be cut a little)

And to answer your question, how to check if your preview ratio is correct? Then get height and width of parameters that you set in:

mCamera.setParameters(parameters);

your set ratio is equal to height/width. If you want camera to look good on your screen then height/width ratio of parameters that you set to camera must be the same as height(minus status bar)/width ratio of your screen.

You could do this but the T generic parameter needs to be declared at the containing class:

public class Foo<T>
{
    public List<T> NewList { get; set; }
}

In a static class, keep a static const integer, then add 1 to it before every single access (using a public get property). This will ensure you cycle the whole int range before you get a non-unique value.

    /// <summary>
    /// The command id to use. This is a thread-safe id, that is unique over the lifetime of the process. It changes
    /// at each access.
    /// </summary>
    internal static int NextCommandId
    {
        get
        {
            return _nextCommandId++;
        }
    }       
    private static int _nextCommandId = 0;

This will produce a unique integer value within a running process. Since you do not explicitly define how unique your integer should be, this will probably fit.

I am looking for the same problem and here is what help me. Here is the jQuery version 3.1.0 and the load event is deprecated for use since jQuery version 1.8. The load event is removed from jQuery 3.0. Instead, you can use on method and bind the JavaScript load event:

$(window).on('load', function () {
  alert("Window Loaded");
});

I would like just to add that if you want to use windows socket library you have to :

• at the beginning : call WSAStartup()

• at the end : call WSACleanup()

Cast(columnName as Numeric(10,2)) 
        or

Cast(@s as decimal(10,2))

I am not getting why you want to cast to varchar?.If you cast to varchar again convert back to decimail for two decimal points

If you have a good reason to set aside culture-dependent formatting and get explicit control over whether or not there's a space between the value and the "%", and whether the "%" is leading or trailing, you can use NumberFormatInfo's PercentPositivePattern and PercentNegativePattern properties.

For example, to get a decimal value with a trailing "%" and no space between the value and the "%":

myValue.ToString("P2", new NumberFormatInfo { PercentPositivePattern = 1, PercentNegativePattern = 1 });

More complete example:

using System.Globalization; 

...

decimal myValue = -0.123m;
NumberFormatInfo percentageFormat = new NumberFormatInfo { PercentPositivePattern = 1, PercentNegativePattern = 1 };
string formattedValue = myValue.ToString("P2", percentageFormat); // "-12.30%" (in en-us)

Whilst Elad's solution will work, you can also do it inline:

   -moz-animation: fadeinphoto 7s 20s infinite;
-webkit-animation: fadeinphoto 7s 20s infinite;
     -o-animation: fadeinphoto 7s 20s infinite;
        animation: fadeinphoto 7s 20s infinite;

Using Sieve of Eratosthenes logic, I am able to achieve the same results with much faster speed.

My code demo VS accepted answer.

Comparing the count, my code takes significantly lesser iteration to finish the job. Checkout the results for different N values in the end.

Why this code performs better than already accepted ones:

- the even numbers are not checked even once throughout the process.

- both inner and outer loops are checking only within possible limits. No extraneous checks.

Code:

int N = 1000; //Print primes number from 1 to N
vector<bool> primes(N, true);
for(int i = 3; i*i < N; i += 2){    //Jump of 2
    for(int j = 3; j*i < N; j+=2){  //Again, jump of 2
        primes[j*i] = false;
    }
}
if(N >= 2) cout << "2 ";
for(int i = 3; i < N; i+=2){        //Again, jump of 2
    if(primes[i] == true) cout << i << " "; 
}

For N = 1000, my code takes 1166 iterations, accepted answer takes 5287 (4.5 times slower)

For N = 10000, my code takes 14637 iterations, accepted answer takes 117526 (8 times slower)

For N = 100000, my code takes 175491 iterations, accepted answer takes 2745693 (15.6 times slower)

You can use the maven.javadoc.skip property to skip execution of the plugin, going by the Mojo's javadoc. You can specify the value as a Maven property:

<properties>
    <maven.javadoc.skip>true</maven.javadoc.skip>
</properties>

or as a command-line argument: -Dmaven.javadoc.skip=true, to skip generation of the Javadocs.

As mentioned by others, by default the tight layout does not take suptitle into account. However, I have found it is possible to use the bbox_extra_artists argument to pass in the suptitle as a bounding box that should be taken into account:

st = fig.suptitle("My Super Title")
plt.savefig("figure.png", bbox_extra_artists=[st], bbox_inches='tight')

This forces the tight layout calculation to take the suptitle into account, and it looks as you would expect.

In Win7 (and Vista I think), you can Shift+Right Click the file in question and select Copy as path to get the full network path. Note: if the shared drive is mapped to a letter, you will get that path instead (ie: X:\someguy\somefile.xls)

I needed to do this with a huge list, and duplicating the list seemed expensive, especially since in my case the number of deletions would be few compared to the items that remain. I took this low-level approach.

array = [lots of stuff]
arraySize = len(array)
i = 0
while i < arraySize:
    if someTest(array[i]):
        del array[i]
        arraySize -= 1
    else:
        i += 1

What I don't know is how efficient a couple of deletes are compared to copying a large list. Please comment if you have any insight.

The idea here is to install multiple ipython kernels. Here are instructions for anaconda. If you are not using anaconda, I recently added instructions using pure virtualenvs.

Anaconda >= 4.1.0

Since version 4.1.0, anaconda includes a special package nb_conda_kernels that detects conda environments with notebook kernels and automatically registers them. This makes using a new python version as easy as creating new conda environments:

conda create -n py27 python=2.7 ipykernel
conda create -n py36 python=3.6 ipykernel

After a restart of jupyter notebook, the new kernels are available over the graphical interface. Please note that new packages have to be explicitly installed into the new environments. The Managing environments section in conda's docs provides further information.

Manually registering kernels

Users who do not want to use nb_conda_kernels or still use older versions of anaconda can use the following steps to manually register ipython kernels.

configure the python2.7 environment:

conda create -n py27 python=2.7
conda activate py27
conda install notebook ipykernel
ipython kernel install --user

configure the python3.6 environment:

conda create -n py36 python=3.6
conda activate py36
conda install notebook ipykernel
ipython kernel install --user

After that you should be able to choose between python2
and python3 when creating a new notebook in the interface.

Additionally you can pass the --name and --display-name options to ipython kernel install if you want to change the names of your kernels. See ipython kernel install --help for more informations.

The properties center, bounds and frame are interlocked: changing one will update the others, so use them however you want. For example, instead of modifying the x/y params of frame to recenter a view, just update the center property.

,reset() method does not clear the default values and checkbox field and there are many more issues.

One thing that I noticed when trying this solution is that if you have N/A at the start or the end of the array, ffill and bfill don't quite work. You need both.

In [224]: df = pd.DataFrame([None, 1, 2, 3, None, 4, 5, 6, None])

In [225]: df.ffill()
Out[225]:
     0
0  NaN
1  1.0
...
7  6.0
8  6.0

In [226]: df.bfill()
Out[226]:
     0
0  1.0
1  1.0
...
7  6.0
8  NaN

In [227]: df.bfill().ffill()
Out[227]:
     0
0  1.0
1  1.0
...
7  6.0
8  6.0

This happened when you call getActivity() in another thread that finished after the fragment has been removed. The typical case is calling getActivity() (ex. for a Toast) when an HTTP request finished (in onResponse for example).

To avoid this, you can define a field name mActivity and use it instead of getActivity(). This field can be initialized in onAttach() method of Fragment as following:

@Override
public void onAttach(Context context) {
    super.onAttach(context);

    if (context instanceof Activity){
        mActivity =(Activity) context;
    }
}

In my projects, I usually define a base class for all of my Fragments with this feature:

public abstract class BaseFragment extends Fragment {

    protected FragmentActivity mActivity;

    @Override
public void onAttach(Context context) {
    super.onAttach(context);

    if (context instanceof Activity){
        mActivity =(Activity) context;
    }
}
}

I am adding for completion a simple function, using only numpy operators:

   def probs_to_onehot(output_probabilities):
        argmax_indices_array = np.argmax(output_probabilities, axis=1)
        onehot_output_array = np.eye(np.unique(argmax_indices_array).shape[0])[argmax_indices_array.reshape(-1)]
        return onehot_output_array

It takes as input a probability matrix: e.g.:

[[0.03038822 0.65810204 0.16549407 0.3797123 ] ... [0.02771272 0.2760752 0.3280924 0.33458805]]

And it will return

[[0 1 0 0] ... [0 0 0 1]]

I would recommend using Wireshark, which has a "Follow TCP Stream" option that makes it very easy to see the full requests and responses for a particular TCP connection. If you would prefer to use the command line, you can try tcpflow, a tool dedicated to capturing and reconstructing the contents of TCP streams.

Other options would be using an HTTP debugging proxy, like Charles or Fiddler as EricLaw suggests. These have the advantage of having specific support for HTTP to make it easier to deal with various sorts of encodings, and other features like saving requests to replay them or editing requests.

You could also use a tool like Firebug (Firefox), Web Inspector (Safari, Chrome, and other WebKit-based browsers), or Opera Dragonfly, all of which provide some ability to view the request and response headers and bodies (though most of them don't allow you to see the exact byte stream, but instead how the browsers parsed the requests).

And finally, you can always construct requests by hand, using something like telnet, netcat, or socat to connect to port 80 and type the request in manually, or a tool like htty to help easily construct a request and inspect the response.

You can create elements to the DOM, which loads items.

Like such:

var myScript = document.createElement('script'); // Create new script element
myScript.type = 'text/javascript'; // Set appropriate type
myScript.src = './js/myclass.js'; // Load javascript file

json might not be the best choice for on-disk formats; The trouble it has with appending data is a good example of why this might be. Specifically, json objects have a syntax that means the whole object must be read and parsed in order to understand any part of it.

Fortunately, there are lots of other options. A particularly simple one is CSV; which is supported well by python's standard library. The biggest downside is that it only works well for text; it requires additional action on the part of the programmer to convert the values to numbers or other formats, if needed.

Another option which does not have this limitation is to use a sqlite database, which also has built-in support in python. This would probably be a bigger departure from the code you already have, but it more naturally supports the 'modify a little bit' model you are apparently trying to build.

You could also use regex to delete all the console.log() calls in your code if they're no longer required. Any decent IDE will allow you to search and replace these across an entire project, and allow you to preview the matches before committing the change.

\s*console\.log\([^)]+\);

The first parameter to the iterator in forEach is the value and second is the key of the object.

angular.forEach(objectToIterate, function(value, key) {
    /* do something for all key: value pairs */
});

In your example, the outer forEach is actually:

angular.forEach($scope.filters, function(filterObj , filterKey)

The simplest way I manage to solve the issue was is by using a ZStack + .edgesIgnoringSafeArea(.all)

struct TestView : View {

    var body: some View {
        ZStack() {
            Color.yellow.edgesIgnoringSafeArea(.all)
            VStack {
                Text("Hello World")
            }
        }
    }
}

works for me:

<target name="build2-jar" depends="compile" >
   <jar destfile="./myJjar.jar">
        <fileset dir="./WebContent/WEB-INF/lib" includes="hibernate*.jar,mysql*.jar" />
        <fileset dir="./WebContent/WEB-INF/classes" excludes="**/controlador/*.class,**/form/*.class,**/orm/*.class,**/reporting/*.class,**/org/w3/xmldsig/*.class"/>
   </jar>

Look at the r.status_code attribute:

if r.status_code == 404:
    # A 404 was issued.

Demo:

>>> import requests
>>> r = requests.get('http://httpbin.org/status/404')
>>> r.status_code
404

If you want requests to raise an exception for error codes (4xx or 5xx), call r.raise_for_status():

>>> r = requests.get('http://httpbin.org/status/404')
>>> r.raise_for_status()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "requests/models.py", line 664, in raise_for_status
    raise http_error
requests.exceptions.HTTPError: 404 Client Error: NOT FOUND
>>> r = requests.get('http://httpbin.org/status/200')
>>> r.raise_for_status()
>>> # no exception raised.

You can also test the response object in a boolean context; if the status code is not an error code (4xx or 5xx), it is considered ‘true’:

if r:
    # successful response

If you want to be more explicit, use if r.ok:.

In addition to the above mentioned answers: I wanted to start a job with a simple parameter passed to a second pipeline and found the answer on http://web.archive.org/web/20160209062101/https://dzone.com/refcardz/continuous-delivery-with-jenkins-workflow

Like I've written in a comment, this problem is probably related to this SO answer.

In short: there are multiple ways to verify the certificate. The verification used by OpenSSL is incompatible with the trusted root certificates you have on your system. OpenSSL is used by Python.

You could try to get the missing certificate for Verisign Class 3 Public Primary Certification Authority and then use the cafile option according to the Python documentation:

urllib2.urlopen(req, cafile="verisign.pem")

This will do it with border-collapse

table{
    border-collapse:collapse;
}

Had same problem - it was somewhere in the ca certificate, so I used the ca bundle used for curl, and it worked. You can download the curl ca bundle here: https://curl.haxx.se/docs/caextract.html

I ran into this error because I was attempting to write a string to a cell which started with an "=".

The solution was to put an "'" (apostrophe) before the equals sign, which is a way to tell excel that you're not, in fact, trying to write a formula, and just want to print the equals sign.

For those who can't (or don't want to) setup a debugger to track down the original exception which was causing the rollback-flag to get set, you can just add a bunch of debug statements throughout your code to find the lines of code which trigger the rollback-only flag:

logger.debug("Is rollbackOnly: " + TransactionAspectSupport.currentTransactionStatus().isRollbackOnly());

Adding this throughout the code allowed me to narrow down the root cause, by numbering the debug statements and looking to see where the above method goes from returning "false" to "true".

In Visual Studio 2012, open the Options dialog (Tools -> Options). Under Environment -> General, the first setting is "Color theme." You can use this to switch between Light and Dark.

The shell theme is distinct from the editor theme--you can use any editor fonts and colors settings with either shell theme.

There is also a Color Theme Editor extension that can be used to create new themes.

You could drop any indexes on the table, then do your insert, and then recreate the indexes.

Separate your rules with a semi colon in a single declaration:

<span style="color:blue;font-style:italic">Test</span>

You must realize what options Jackson has available for deserialization. In Java, method argument names are not present in the compiled code. That's why Jackson can't generally use constructors to create a well-defined object with everything already set.

So, if there is an empty constructor and there are also setters, it uses the empty constructor and setters. If there are no setters, some dark magic (reflections) is used to do it.

If you want to use a constructor with Jackson, you must use the annotations as mentioned by @PiersyP in his answer. You can also use a builder pattern. If you encounter some exceptions, good luck. Error handling in Jackson sucks big time, it's hard to understand that gibberish in error messages.

Pass true as the append parameter of the constructor:

TextWriter tsw = new StreamWriter(@"C:\Hello.txt", true);

It worked for me you can try your: Add this to VM options in Tomcat

-DdevBaseDir="C:\Your_Project_Dir_Path"

Short answer: Why not?

Longer answer: The time itself doesn't really matter, as long as everyone who uses it agrees on its value. As 1/1/70 has been in use for so long, using it will make you code as understandable as possible for as many people as possible.

There's no great merit in choosing an arbitrary epoch just to be different.

This is my solution which perfectly works starting from API 15. This solution keeps all default button click effects, like material RippleEffect. I have not tested it on lower APIs, but it should work.

All you need to do, is:

1) Create a style which changes only colorAccent:

<style name="Facebook.Button" parent="ThemeOverlay.AppCompat">
    <item name="colorAccent">@color/com_facebook_blue</item>
</style>

I recommend using ThemeOverlay.AppCompat or your main AppTheme as parent, to keep the rest of your styles.

2) Add these two lines to your button widget:

style="@style/Widget.AppCompat.Button.Colored"
android:theme="@style/Facebook.Button"

Sometimes your new colorAccent isn't showing in Android Studio Preview, but when you launch your app on the phone, the color will be changed.

Sample Button widget

<Button
    android:id="@+id/sign_in_with_facebook"
    style="@style/Widget.AppCompat.Button.Colored"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:text="@string/sign_in_facebook"
    android:textColor="@android:color/white"
    android:theme="@style/Facebook.Button" />

You should not wrap JavaScript expressions in quotes.

<option data-img-src={this.props.imageUrl} value="1">{this.props.title}</option>

Take a look at the JavaScript Expressions docs for more info.

Instead of setting height property, use min-height.

I had some problems with the insertion process just like you, so here is the code how I have solved the problem:

void add_by_position(int data, int pos)
  {
        link *node = new link;
        link *linker = head;

        node->data = data;
        for (int i = 0; i < pos; i++){
            linker = linker->next;
        }
        node->next = linker;
        linker = head;
        for (int i = 0; i < pos - 1; i++){
            linker = linker->next;
        }
        linker->next = node;
        boundaries++;
    }

You may also consider the following solution:

let sum = options.set0.concat(options.set1);
const codeHTML = '<ol>' + sum.reduce((html, item) => {
    return html + "<li>" + item + "</li>";
        }, "") + '</ol>';
document.querySelector("#list").innerHTML = codeHTML;

You can also use the required module.

require('./componentName.css');
const React = require('react');

Another option is

if your purpose is analyse your query, Notepad+ has useful automatic wrapper for Sql.

Plugin eregex.vim handles Perl-style non-greedy operators *? and +?

You should stick to the NSInteger data types when possible. So you'd create the number like that:

NSInteger myValue = 1;
NSNumber *number = [NSNumber numberWithInteger: myValue];

Decoding works with the integerValue method then:

NSInteger value = [number integerValue];

I found another way to convert an object to a byte[], here is my solution:

IEnumerable en = (IEnumerable) myObject;
byte[] myBytes = en.OfType<byte>().ToArray();

This is a bit of an old question, but I thought I would contribute my 2 cents anyway since this thread came up in conversation today.

This doesn't exactly answer why is there no const? but how to make your classes immutable. (Unfortunately I have not enough reputation yet to post as a comment to the accepted answer)

The way to guarantee immutability on an object is to design your classes more carefully to be immutable. This requires a bit more care than a mutable class.

This goes back to Josh Bloch's Effective Java Item 15 - Minimize Mutability. If you haven't read the book, pick up a copy and read it over a few times I guarantee it will up your figurative "java game".

In item 15 Bloch suggest that you should limit the mutability of classes to ensure the object's state.

To quote the book directly:

An immutable class is simply a class whose instances cannot be modified. All of the information contained in each instance is provided when it is created and is fixed for the lifetime of the object. The Java platform libraries contain many immutable classes, including String, the boxed primitive classes, and BigInte- ger and BigDecimal. There are many good reasons for this: Immutable classes are easier to design, implement, and use than mutable classes. They are less prone to error and are more secure.

Bloch then describes how to make your classes immutable, by following 5 simple rules:

1. Don’t provide any methods that modify the object’s state (i.e., setters, aka mutators)
2. Ensure that the class can’t be extended (this means declaring the class itself as final).
3. Make all fields final.
4. Make all fields private.
5. Ensure exclusive access to any mutable components. (by making defensive copies of the objects)

For more details I highly recommend picking up a copy of the book.

I don't know a built-in function, but writing one like this shouldn't be too complicated.

def frange(x, y, jump):
  while x < y:
    yield x
    x += jump

As the comments mention, this could produce unpredictable results like:

>>> list(frange(0, 100, 0.1))[-1]
99.9999999999986

To get the expected result, you can use one of the other answers in this question, or as @Tadhg mentioned, you can use decimal.Decimal as the jump argument. Make sure to initialize it with a string rather than a float.

>>> import decimal
>>> list(frange(0, 100, decimal.Decimal('0.1')))[-1]
Decimal('99.9')

Or even:

import decimal

def drange(x, y, jump):
  while x < y:
    yield float(x)
    x += decimal.Decimal(jump)

And then:

>>> list(drange(0, 100, '0.1'))[-1]
99.9

As noted previously, having an extra comma threw an error.

Also in IE 7.0, not having a semicolon at the end of a line caused an error. It works fine in Safari and Chrome (with no errors in console).

Just check if response[0] is undefined:

if(response[0] !== undefined) { ... }

If you still need to explicitly check the title, do so after the initial check:

if(response[0] !== undefined && response[0].title !== undefined){ ... }

Getting an ECONNREFUSED errno means that your kernel was refused a connection at the other end, so if it's a bug, it's either in your kernel or in the other end. What you can do is to trap the error in a very specific way and try again in a little while, since this seems to work:

# This is Python > 2.5 code
import errno, time

for attempt in range(MAXIMUM_NUMBER_OF_ATTEMPTS):
    try:
        # your urllib call here
    except EnvironmentError as exc: # replace " as " with ", " for Python<2.6
        if exc.errno == errno.ECONNREFUSED:
            time.sleep(A_COUPLE_OF_SECONDS)
        else:
            raise # re-raise otherwise
    else: # we tried, and we had no failure, so
        break
else: # we never broke out of the for loop
    raise RuntimeError("maximum number of unsuccessful attempts reached")

Replace the two all-caps constants with your favourite numbers.

For makecert, your startInfo.FileName should be the complete path of makecert (or just makecert.exe if it's in standard path) then the Arguments would be -sk server -sky exchange -pe -n CN=localhost -ir LocalMachine -is Root -ic MyCA.cer -sr LocalMachine -ss My MyAdHocTestCert.cer now I'm bit unfamiliar with how certificate store works, but perhaps you'll need to set startInfo.WorkingDirectory if you're referring the .cer files outside the certificate store

I dont believe you can without cropping them, I mean you could make the divs the same height by using jquery however this will not make the images the same size.

You could take a look at using Masonry which will make this look decent.

http://masonry.desandro.com/

 $('.checkbox').attr('checked',true);

will not work with from jQuery 1.6.

Instead use

$('.checkbox').prop('checked',true);
$('.checkbox').prop('checked',false);

Full explanation / examples and demo can be found in the jQuery API Documentation https://api.jquery.com/attr/

I know this answer is late, but I combined a bunch of answers and made a simple function that works for all use cases.

Try this:

function is_ssl(){
if(isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO']=="https"){ return true; }
elseif(isset($_SERVER['HTTPS'])){ return true; }
elseif($_SERVER['SERVER_PORT'] == 443){ return true; }
else{ return false; }
}

Then just use if, for example:

if(is_ssl()){
// WHAT TO DO IF IT IS SSL / HTTPS
}else{
// WHAT TO DO IF IT IS NOT SSL / HTTPS
}

This code works with Cloudflare, shared hosting providers, etc.

Enjoy.

You can use bubbling in your favor:

$('.foobar').on('click', function(e) {
    // do your thing.
}).on('click', 'div', function(e) {
    // clicked on descendant div
    e.stopPropagation();
});

$ ls -ld directory

ls is the list command.

- indicates the beginning of the command options.

l asks for a long list which includes the permissions.

d indicates that the list should concern the named directory itself; not its contents. If no directory name is given, the list output will pertain to the current directory.

Short Answer:

You likely want to use gpg instead of openssl so see "Additional Notes" at the end of this answer. But to answer the question using openssl:

To Encrypt:

openssl enc -aes-256-cbc -in un_encrypted.data -out encrypted.data

To Decrypt:

openssl enc -d -aes-256-cbc -in encrypted.data -out un_encrypted.data

Note: You will be prompted for a password when encrypting or decrypt.

Long Answer:

Your best source of information for openssl enc would probably be: https://www.openssl.org/docs/man1.1.1/man1/enc.html

Command line: openssl enc takes the following form:

openssl enc -ciphername [-in filename] [-out filename] [-pass arg]
[-e] [-d] [-a/-base64] [-A] [-k password] [-kfile filename] 
[-K key] [-iv IV] [-S salt] [-salt] [-nosalt] [-z] [-md] [-p] [-P] 
[-bufsize number] [-nopad] [-debug] [-none] [-engine id]

Explanation of most useful parameters with regards to your question:

-e
    Encrypt the input data: this is the default.

-d    
    Decrypt the input data.

-k <password>
    Only use this if you want to pass the password as an argument. 
    Usually you can leave this out and you will be prompted for a 
    password. The password is used to derive the actual key which 
    is used to encrypt your data. Using this parameter is typically
    not considered secure because your password appears in 
    plain-text on the command line and will likely be recorded in 
    bash history.

-kfile <filename>
    Read the password from the first line of <filename> instead of
    from the command line as above.

-a
    base64 process the data. This means that if encryption is taking 
    place the data is base64 encoded after encryption. If decryption 
    is set then the input data is base64 decoded before being 
    decrypted.
    You likely DON'T need to use this. This will likely increase the
    file size for non-text data. Only use this if you need to send 
    data in the form of text format via email etc.

-salt
    To use a salt (randomly generated) when encrypting. You always
    want to use a salt while encrypting. This parameter is actually
    redundant because a salt is used whether you use this or not 
    which is why it was not used in the "Short Answer" above!

-K key    
    The actual key to use: this must be represented as a string
    comprised only of hex digits. If only the key is specified, the
    IV must additionally be specified using the -iv option. When 
    both a key and a password are specified, the key given with the
    -K option will be used and the IV generated from the password 
    will be taken. It probably does not make much sense to specify 
    both key and password.

-iv IV
    The actual IV to use: this must be represented as a string 
    comprised only of hex digits. When only the key is specified 
    using the -K option, the IV must explicitly be defined. When a
    password is being specified using one of the other options, the 
    IV is generated from this password.

-md digest
    Use the specified digest to create the key from the passphrase.
    The default algorithm as of this writing is sha-256. But this 
    has changed over time. It was md5 in the past. So you might want
    to specify this parameter every time to alleviate problems when
    moving your encrypted data from one system to another or when
    updating openssl to a newer version.

Additional Notes:

Though you have specifically asked about OpenSSL you might want to consider using GPG instead for the purpose of encryption based on this article OpenSSL vs GPG for encrypting off-site backups?

To use GPG to do the same you would use the following commands:

To Encrypt:

gpg --output encrypted.data --symmetric --cipher-algo AES256 un_encrypted.data

To Decrypt:

gpg --output un_encrypted.data --decrypt encrypted.data

Note: You will be prompted for a password when encrypting or decrypt.

You could use module scope. Say you have a module called utils:

f_value = 'foo'

def f():
    return f_value

f_value is a module attribute that can be modified by any other module that imports it. As modules are singletons, any change to utils from one module will be accessible to all other modules that have it imported:

>> import utils
>> utils.f()
'foo'
>> utils.f_value = 'bar'
>> utils.f()
'bar'

Note that you can import the function by name:

>> import utils
>> from utils import f
>> utils.f_value = 'bar'
>> f()
'bar'

But not the attribute:

>> from utils import f, f_value
>> f_value = 'bar'
>> f()
'foo'

This is because you're labeling the object referenced by the module attribute as f_value in the local scope, but then rebinding it to the string bar, while the function f is still referring to the module attribute.

Limit - 30 symbols. Username must contains only letters, numbers, periods and underscores.

In Rails 5 you can use ActiveRecord::Type::Boolean.new.cast(value) to cast it to a boolean.

The new C# 8.0 range operator can be a great shortcut to achieve this.

Example #1 (to answer the question):

string myString = "abcdxxx";
var shortenedString = myString[0..^3]
System.Console.WriteLine(shortenedString);
// Results: abcd

Example #2 (to show you how awesome range operators are):

string s = "FooBar99";
// If the last 2 characters of the string are 99 then change to 98
s = s[^2..] == "99" ? s[0..^2] + "98" : s;
System.Console.WriteLine(s);
// Results: FooBar98

If you are using a command to just call curl like that, you can do the same thing in Python with subprocess. Example:

subprocess.call(['curl', '-i', '-H', '"Accept: application/xml"', '-u', 'login:key', '"https://app.streamsend.com/emails"'])

Or you could try PycURL if you want to have it as a more structured api like what PHP has.

If you don't want to use setMaxResults, you can also use Query.scroll instead of list, and fetch the rows you desire. Useful for paging for instance.

Global variables are not extern nor static by default on C and C++. When you declare a variable as static, you are restricting it to the current source file. If you declare it as extern, you are saying that the variable exists, but are defined somewhere else, and if you don't have it defined elsewhere (without the extern keyword) you will get a link error (symbol not found).

Your code will break when you have more source files including that header, on link time you will have multiple references to varGlobal. If you declare it as static, then it will work with multiple sources (I mean, it will compile and link), but each source will have its own varGlobal.

What you can do in C++, that you can't in C, is to declare the variable as const on the header, like this:

const int varGlobal = 7;

And include in multiple sources, without breaking things at link time. The idea is to replace the old C style #define for constants.

If you need a global variable visible on multiple sources and not const, declare it as extern on the header, and then define it, this time without the extern keyword, on a source file:

Header included by multiple files:

extern int varGlobal;

In one of your source files:

int varGlobal = 7;

I tried using performance.now() to analyze the performance of the different types of loops. I took a very large array and found the sum of all elements of the array. I ran the code three times every time and found forEach and reduce to be a clear winner.

Just developed solution to detect when scrolling finished app-wide: https://gist.github.com/k06a/731654e3168277fb1fd0e64abc7d899e

It is based on idea of tracking changes of runloop modes. And perform blocks at least after 0.2 seconds after scrolling.

This is core idea for tracking runloop modes changes iOS10+:

- (void)tick {
    [[NSRunLoop mainRunLoop] performInModes:@[ UITrackingRunLoopMode ] block:^{
        [self tock];
    }];
}

- (void)tock {
    self.runLoopModeWasUITrackingAgain = YES;
    [[NSRunLoop mainRunLoop] performInModes:@[ NSDefaultRunLoopMode ] block:^{
        [self tick];
    }];
}

And solution for low deployment targets like iOS2+:

- (void)tick {
    [[NSRunLoop mainRunLoop] performSelector:@selector(tock) target:self argument:nil order:0 modes:@[ UITrackingRunLoopMode ]];
}

- (void)tock {
    self.runLoopModeWasUITrackingAgain = YES;
    [[NSRunLoop mainRunLoop] performSelector:@selector(tick) target:self argument:nil order:0 modes:@[ NSDefaultRunLoopMode ]];
}

Suppose .. if we have more than 20 process running on the server with the same name ... this will not help

top -p pgrep oracle | head -n 20 | tr "\\n" "," | sed 's/,$//'

It will try to list and provide real time output of 20 process where we have good chance of missing other prcesses which consumes more resource ....

I am still looking for better option on this

Check which version of Entity Framework reference you have in your References and make sure that it matches with your configSections node in Web.config file. In my case it was pointing to version 5.0.0.0 in my configSections and my reference was 6.0.0.0. I just changed it and it worked...

<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/>

function bookmark(title, url) {
  if (window.sidebar) { 
    // Firefox
    window.sidebar.addPanel(title, url, '');
  } 
  else if (window.opera && window.print) 
  { 
    // Opera
    var elem = document.createElement('a');
    elem.setAttribute('href', url);
    elem.setAttribute('title', title);
    elem.setAttribute('rel', 'sidebar');
    elem.click(); //this.title=document.title;
  } 
  else if (document.all) 
  { 
    // ie
    window.external.AddFavorite(url, title);
  }
}

I used this & works great in IE, FF, Netscape. Chrome, Opera and safari do not support it!

@media (min-width: $screen-md) {
    .col-md-15 {
        width: 20%;

Non of them worked for me. I did this and it worked:

To encode as a json:

JSONObject obj = new JSONObject();
obj.put("productId", 100);

To decode:

long temp = (Long) obj.get("productId");

Thanks to @Gerben's post came to know there are two events show.bs.tab (before the tab is shown) and shown.bs.tab (after the tab is shown) as explained in the docs - Bootstrap Tab usage

An additional solution if we're only interested in a specific tab, and maybe add separate functions without having to add an if - else block in one function, is to use the a href selector (maybe along with additional selectors if required)

 $("a[href='#tab_target_id']").on('shown.bs.tab', function(e) {
      console.log('shown - after the tab has been shown');
 });

 // or even this one if we want the earlier event
 $("a[href='#tab_target_id']").on('show.bs.tab', function(e) {
      console.log('show - before the new tab has been shown');
 });

If that is the case, I think you need to use a better way of creating a class name or a class name convention. For example, like you said you want the .container class to have different color according to a specific usage or appearance. You can do this:

SCSS

.container {
  background: red;

  &--desc {
    background: blue;
  }

  // or you can do a more specific name
  &--blue {
    background: blue;
  }

  &--red {
    background: red;
  }
}

CSS

.container {
  background: red;
}

.container--desc {
  background: blue;
}

.container--blue {
  background: blue;
}

.container--red {
  background: red;
}

The code above is based on BEM Methodology in class naming conventions. You can check this link: BEM — Block Element Modifier Methodology

According to Java Persistence with Hibernate

mapping collections of value types with annotations [...]. At the time of writing it isn't part of the Java Persistence standard

If you were using Hibernate, you could do something like:

@org.hibernate.annotations.CollectionOfElements(
    targetElement = java.lang.String.class
)
@JoinTable(
    name = "foo",
    joinColumns = @JoinColumn(name = "foo_id")
)
@org.hibernate.annotations.IndexColumn(
    name = "POSITION", base = 1
)
@Column(name = "baz", nullable = false)
private List<String> arguments = new ArrayList<String>();

Update: Note, this is now available in JPA2.

Yes, it's safe to delete these, although it may force a dynamic recompilation of any .NET applications you run on the server.

For background, see the Understanding ASP.NET dynamic compilation article on MSDN.

I think the short answer is "because it is of zero usefulness". To call an interface method, you need an instance of the type. From instance methods you can call any static methods you want to.

On the newer versions of macOS, one also has to set java.library.path. The easiest/safest way to do that [1] is by creating ~/.sqldeveloper/<version>/sqldeveloper.conf file and populating it as such:

AddVMOption -Djava.library.path=<instant client directory>

xsd.exe does not work well when you have circular references (ie a type can own an element of its own type directly or indirectly).

When circular references exist, I use Xsd2Code. Xsd2Code handles circular references well and works within the VS IDE, which is a big plus. It also has a lot of features you can use like generating the serialization/deserialization code. Make sure you turn on the GenerateXMLAttributes if you are generating serialization though (otherwise you'll get exceptions for ordering if not defined on all elements).

Neither works well with the choice feature. you'll end up with lists/collections of object instead of the type you want. I'd recommend avoiding choice in your xsd if possible as this does not serialize/deserialize well into a strongly typed class. If you don't care about this, though, then it's not a problem.

The any feature in xsd2code deserializes as System.Xml.XmlElement which I find really convenient but may be an issue if you want strong typed objects. I often use any when allowing custom config data, so an XmlElement is convenient to pass to another XML deserializer that is custom defined elsewhere.

In the example you gave, the method will never throw an IOException, therefore the declaration is wrong (but valid). My guess is that the original method threw the IOException, but it was then updated to handle the exception within but the declaration was not changed.

__FUNCTION__ is non standard, __func__ exists in C99 / C++11. The others (__LINE__ and __FILE__) are just fine.

It will always report the right file and line (and function if you choose to use __FUNCTION__/__func__). Optimization is a non-factor since it is a compile time macro expansion; it will never affect performance in any way.

I thought I could add a method I use in many projects.

- (NSInteger)randomValueBetween:(NSInteger)min and:(NSInteger)max {
    return (NSInteger)(min + arc4random_uniform(max - min + 1));
}

If I end up using it in many files I usually declare a macro as

#define RAND_FROM_TO(min, max) (min + arc4random_uniform(max - min + 1))

E.g.

NSInteger myInteger = RAND_FROM_TO(0, 74) // 0, 1, 2,..., 73, 74

In my case, the command that best suited me was:

jupyter nbconvert --execute --clear-output <notebook>.ipynb

Why? This command does not create extra files (just like a .py file) and the output of the cells is overwritten everytime the notebook is executed.

If you run:

jupyter nbconvert --help

--clear-output Clear output of current file and save in place, overwriting the existing notebook.

The syntax of TINYINT data type is TINYINT(M),

where M indicates the maximum display width (used only if your MySQL client supports it).

The (m) indicates the column width in SELECT statements; however, it doesn't control the accepted range of numbers for that field.

A TINYINT is an 8-bit integer value, a BIT field can store between 1 bit, BIT(1), and 64 >bits, BIT(64). For a boolean values, BIT(1) is pretty common.

TINYINT()

You can accomplish the same solution as @paxdiablo's using just findstr by itself. There's no need to pipe multiple commands together:

findstr /V "ERROR REFERENCE" infile.txt > outfile.txt

Details of how this works:

• /v finds lines that don't match the search string (same switch @paxdiablo uses)
• if the search string is in quotes, it performs an OR search, using each word (separator is a space)
• findstr can take an input file, you don't need to feed it the text using the "type" command
• "> outfile.txt" will send the results to the file outfile.txt instead printing them to your console. (Note that it will overwrite the file if it exists. Use ">> outfile.txt" instead if you want to append.)
• You might also consider adding the /i switch to do a case-insensitive match.

There is not a single function that will do that, because 0 is a valid number and you need to be able to catch when the string is not a valid number.

You will need to check the string first (probably with a regular expression) to see if it contains only numbers and numerical punctuation. You can then decide to return 0 if that is what your application needs or convert it to a double.

After looking up atof() and strtod() I should rephrase my statement to "there shouldn't be" instead of "there is not" ... hehe

You can comma-separate shadows:

box-shadow: inset 0 2px 0px #dcffa6, 0 2px 5px #000;

This will

#myDiv
{
    cursor: pointer;
}

I'd use standard javascript:

for (var m in myMap){
    for (var i=0;i<myMap[m].length;i++){
    ... do something with myMap[m][i] ...
    }
} 

Note the different ways of treating objects and arrays.

[Hg Tortoise 4.6.1] If it's recent action, you can use "Rollback/Undo" action (Ctrl+U).

First off, you must save your work book as a macro enabled work book. So it would need to be xlsm not an xlsx. Otherwise, excel will disable the macro's due to not being macro enabled.

Set your vbscript (C:\excel\tester.vbs). The example sub "test()" must be located in your modules on the excel document.

dim eApp
set eApp = GetObject("C:\excel\tester.xlsm")
eApp.Application.Run "tester.xlsm!test"
set eApp = nothing

Then set your Schedule, give it a name, and a username/password for offline access.

Then you have to set your actions and triggers.

Set your schedule(trigger)

Action, set your vbscript to open with Cscript.exe so that it will be executed in the background and not get hung up by any error handling that vbcript has enabled.

In the end I found this to be the best solution considering the requirements:

// Expand/Collapse all
$('.accordion-expand-collapse a').click(function() {
    $('.accordion .ui-accordion-header:not(.ui-state-active)').next().slideToggle();
    $(this).text($(this).text() == 'Expand all' ? 'Collapse all' : 'Expand all');
    $(this).toggleClass('collapse');
    return false;
});

The value of the match attribute of the <xsl:template> instruction must be a match pattern.

Match patterns form a subset of the set of all possible XPath expressions. The first, natural, limitation is that a match pattern must select a set of nodes. There are also other limitations. In particular, reverse axes are not allowed in the location steps (but can be specified within the predicates). Also, no variable or parameter references are allowed in XSLT 1.0, but using these is legal in XSLT 2.x.

/ in XPath denotes the root or document node. In XPath 2.0 (and hence XSLT 2.x) this can also be written as document-node().

A match pattern can contain the // abbreviation.

Examples of match patterns:

<xsl:template match="table">

can be applied on any element named table.

<xsl:template match="x/y">

can be applied on any element named y whose parent is an element named x.

<xsl:template match="*">

can be applied to any element.

<xsl:template match="/*">

can be applied only to the top element of an XML document.

<xsl:template match="@*">

can be applied to any attribute.

<xsl:template match="text()">

can be applied to any text node.

<xsl:template match="comment()">

can be applied to any comment node.

<xsl:template match="processing-instruction()">

can be applied to any processing instruction node.

<xsl:template match="node()">

can be applied to any node: element, text, comment or processing instructon.

This also would do it

#imagewrapper {
    text-align:center;
}

#imagewrapper img {
    display:inline-block;
    margin:0 5px;
}

The copy() runs for the least length of dst and src, so you must initialize the dst to the desired length.

A := []int{1, 2, 3}
B := make([]int, 3)
copy(B, A)
C := make([]int, 2)
copy(C, A)
fmt.Println(A, B, C)

Output:

[1 2 3] [1 2 3] [1 2]

You can initialize and copy all elements in one line using append() to a nil slice.

x := append([]T{}, []...)

Example:

A := []int{1, 2, 3}
B := append([]int{}, A...)
C := append([]int{}, A[:2]...)
fmt.Println(A, B, C)    

Output:

[1 2 3] [1 2 3] [1 2]

Comparing with allocation+copy(), for greater than 1,000 elements, use append. Actually bellow 1,000 the difference may be neglected, make it a go for rule of thumb unless you have many slices.

I find the accepted answer, and all the others strange, since they pass self to an abstract class. An abstract class is not instantiated so can't have a self.

So try this, it works.

from abc import ABCMeta, abstractmethod


class Abstract(metaclass=ABCMeta):
    @staticmethod
    @abstractmethod
    def foo():
        """An abstract method. No need to write pass"""


class Derived(Abstract):
    def foo(self):
        print('Hooray!')


FOO = Derived()
FOO.foo()

TL;DR:

Make sure that you not only check the action and category name, but the path. Especially if you did a refactor.

The solution for me was to closely check the AndroidManifest file. I did a refactor, and it not only updated the intent-filters, but it also updated the path of the intent filter name:

 //type and value were added to the path here when I did the refactor
 <action android:name="android.intent.type.MAIN"/>
 <category android:name="android.intent.value.LAUNCHER"/>

It should be:

<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>

try setting this

CATALINA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8 
-server -Xms1536m -Xmx1536m
-XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m 
-XX:MaxPermSize=256m -XX:+DisableExplicitGC"

in {$tomcat-folder}\bin\setenv.sh (create it if necessary).

See http://www.mkyong.com/tomcat/tomcat-javalangoutofmemoryerror-permgen-space/ for more details.

DO NOT use git push origin --mirror UNDER ALMOST ANY CIRCUMSTANCE.

It does not ask if you're sure you want to do this, and you'd better be sure, because it will erase all of your remote branches that are not on your local box.

Check out the instanceof operator.

var isJqueryObject = obj instanceof jQuery

you can use System.Diagnostics.Process.Start as well as WIN32 ShellExecute function by means of interop, for opening PDF files using the default viewer:

System.Diagnostics.Process.Start("SOMEAPP.EXE","Path/SomeFile.Ext");

[System.Runtime.InteropServices.DllImport("shell32. dll")]
private static extern long ShellExecute(Int32 hWnd, string lpOperation, 
                                    string lpFile, string lpParameters, 
                                        string lpDirectory, long nShowCmd);

Another approach is to place a WebBrowser Control into your Form and then use the Navigate method for opening the PDF file:

ThewebBrowserControl.Navigate(@"c:\the_file.pdf");

I like the answers setting border-top, but they are somehow still a little off in Chrome...
BUT if I set border-top: 1px solid black; and border-bottom: 0px; I end up with a truly single line (that also works fine with higher thickness).

Update

The Unconstrained Melody library is no longer maintained; Support was dropped in favour of Enums.NET.

In Enums.NET you'd use:

string description = ((MyEnum)value).AsString(EnumFormat.Description);

Original post

I implemented this in a generic, type-safe way in Unconstrained Melody - you'd use:

string description = Enums.GetDescription((MyEnum)value);

This:

• Ensures (with generic type constraints) that the value really is an enum value
• Avoids the boxing in your current solution
• Caches all the descriptions to avoid using reflection on every call
• Has a bunch of other methods, including the ability to parse the value from the description

I realise the core answer was just the cast from an int to MyEnum, but if you're doing a lot of enum work it's worth thinking about using Unconstrained Melody :)

This is caused because there is a database running on your computer. In my case, it was an Oracle data base. By default, everytime you start your computer, the services of the database automatically starts.

Go to Start >> find Oracle or whatever data-base in the list of programms >> and manually stop the database. It appears that there is a conflict of port.

The selected answer didn't work for me, but it's close. I found a tutorial that worked for me and the certificate I obtained from StartCom.

1. Open the .p7b in a text editor.

2. Change the leader and trailer so the file looks similar to this:

   -----BEGIN PKCS7-----
   [... certificate content here ...]
   -----END PKCS7-----
   

For example, my StartCom certificate began with:

    -----BEGIN CERTIFICATE----- 

and ended with:

    -----END CERTIFICATE----- 

3. Save and close the .p7b.

4. Run the following OpenSSL command (works on Ubuntu 14.04.4, as of this writing):

   openssl pkcs7 -print_certs –in pkcs7.p7b -out pem.cer
   

The output is a .cer with the certificate chain.

Reference: http://www.freetutorialssubmit.com/extract-certificates-from-P7B/2206

You'll want to have 3 directories inside your chosen GOPATH directory.

GOPATH
     /bin
     /src
       /someProgram
        program.go
       /someLibrary
        library.go
     /pkg

Then you'll run go install from inside either someProgram (which puts an executable in bin) or someLibrary (which puts a library in pkg).

currently reopquery is integrated into dnf and yum, so typing:

dnf repoquery -l <pkg-name>

will list package contents from a remote repository (even for the packages that are not installed yet)

meaning installing a separate dnf-utils or yum-utils package is no longer required for the functionality as it is now being supported natively.

for listing installed or local (*.rpm files) packages' contents there is rpm -ql

i don't think it is possible with yum org dnf (not repoquery subcommand)

please correct me if i am wrong

XStream provides a simple utility for serializing/deserializing to/from XML, and it's very quick. Storing XML CLOBs rather than binary BLOBS is going to be less fragile, not to mention more readable.

$pdf->SetY($Y_Fields_Name_position);
$pdf->SetX(#);
$pdf->MultiCell($height,$width,"Line1 \nLine2 \nLine3",1,'C',1);

In every Column, before you set the X Position indicate first the Y position, so it became like this

Column 1

$pdf->SetY($Y_Fields_Name_position);
$pdf->SetX(#);
$pdf->MultiCell($height,$width,"Line1 \nLine2 \nLine3",1,'C',1);

Column 2

$pdf->SetY($Y_Fields_Name_position);
$pdf->SetX(#);
$pdf->MultiCell($height,$width,"Line1 \nLine2 \nLine3",1,'C',1);

I am ridiculously late to this party. I am having success placing the brackets in the replacement element, like this:

Strictly speaking this is not what OP is asking, as s/he wants the braces in the format string, but this may help someone.

I had the same issue every time I tried to create a new project, but based on the console output, it was because of two versions of android-support-v4 that were different:

I don't know a lot about Eclipse. but I simply deleted the copy of the jar file from my project's libs folder so that it would use the appcompat_v7 jar file instead. This fixed my issue.

I also had similar problem where redirects were giving 404 or 405 randomly on my development server. It was an issue with gunicorn instances.

Turns out that I had not properly shut down the gunicorn instance before starting a new one for testing. Somehow both of the processes were running simultaneously, listening to the same port 8080 and interfering with each other. Strangely enough they continued running in background after I had killed all my terminals. Had to kill them manually using fuser -k 8080/tcp

I was searching and testing more about this issue and I realized that static files directories specified in settings.py can be a cause of this, so fist, we need to run this command

python manage.py collectstatic

in settings.py, the code should look something like this:

STATIC_URL = '/static/'

STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),
)

STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')

I had something similar, and here's (an edited) version of what I ended up using successfully:

ISNULL(CONVERT(VARCHAR(50),[column name goes here],[date style goes here] ),'')

Here's why this works: If you select a date which is NULL, it will show return NULL, though it is really stored as 01/01/1900. This is why an ISNULL on the date field, while you're working with any date data type will not treat this as a NULL, as it is technically not being stored as a NULL.

However, once you convert it to a new datatype, it will convert it as a NULL, and at that point, you're ISNULL will work as you expect it to work.

I hope this works out for you as well!

Update, nearly one year later:

I had a similar situation, where I needed the output to be of the date data-type, and my aforementioned solution didn't work (it only works if you need it displayed as a date, not be of the date data type.

If you need it to be of the date data-type, there is a way around it, and this is to nest a REPLACE within an ISNULL, the following worked for me:

Select 
    ISNULL(
        REPLACE(
            [DATE COLUMN NAME],
            '1900-01-01',
            ''
        ),
    '') AS [MeaningfulAlias]

How to Write Doc Comments for the Javadoc Tool

For Query parameters like domain.com/test?format=json&type=mini format, then you can easily receive it via - req.query.

app.get('/test', function(req, res){
  var format = req.query.format,
      type = req.query.type;
});

Try with below command, and it will ask all values to INT

select case when isnumeric(YourColumn + '.0e0') = 1 then cast(YourColumn as int) else NULL end /* case */ from YourTable

This looks like what you need:

$this->db->where('order_date >=', $first_date);
$this->db->where('order_date <=', $second_date);
return $this->db->get('orders');

Using Interface builder you can link and get the event for "Editing changed" in any of your function. Now there you can put check for the length

- (IBAction)onValueChange:(id)sender 
{
    NSString *text = nil;
    int MAX_LENGTH = 20;
    switch ([sender tag] ) 
    {
        case 1: 
        {
            text = myEditField.text;
            if (MAX_LENGTH < [text length]) {
                myEditField.text = [text substringToIndex:MAX_LENGTH];
            }
        }
            break;
        default:
            break;
    }

}

Your stored procedures work as coded. The problem is with the last line, it is unable to invoke either of your stored procedures.

Three choices in SQL*Plus are: call, exec, and an anoymous PL/SQL block.

call appears to be a SQL keyword, and is documented in the SQL Reference. http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_4008.htm#BABDEHHG The syntax diagram indicates that parentesis are required, even when no arguments are passed to the call routine.

CALL test_sp_1();

An anonymous PL/SQL block is PL/SQL that is not inside a named procedure, function, trigger, etc. It can be used to call your procedure.

BEGIN
    test_sp_1;
END;
/

Exec is a SQL*Plus command that is a shortcut for the above anonymous block. EXEC <procedure_name> will be passed to the DB server as BEGIN <procedure_name>; END;

Full example:

SQL> SET SERVEROUTPUT ON
SQL> CREATE OR REPLACE PROCEDURE test_sp 
  2  AS 
  3  BEGIN 
  4      DBMS_OUTPUT.PUT_LINE('Test works'); 
  5  END;
  6  /

Procedure created.

SQL> CREATE OR REPLACE PROCEDURE test_sp_1 
  2  AS
  3  BEGIN
  4      DBMS_OUTPUT.PUT_LINE('Testing'); 
  5      test_sp; 
  6  END;
  7  /

Procedure created.

SQL> CALL test_sp_1();
Testing
Test works

Call completed.

SQL> exec test_sp_1
Testing
Test works

PL/SQL procedure successfully completed.

SQL> begin
  2      test_sp_1;
  3  end;
  4  /
Testing
Test works

PL/SQL procedure successfully completed.

Multiply the number and then divide it by what you multiplied it by before.

For example,

perc = double.Parse("3.555)*1000;
result = perc/1000

The answer

$scope.$watch('$viewContentLoaded', 
    function() { 
        $timeout(function() {
            //do something
        },0);    
});

is the only one that works in most scenarios I tested. In a sample page with 4 components all of which build HTML from a template, the order of events was

$document ready
$onInit
$postLink
(and these 3 were repeated 3 more times in the same order for the other 3 components)
$viewContentLoaded (repeated 3 more times)
$timeout execution (repeated 3 more times)

So a $document.ready() is useless in most cases since the DOM being constructed in angular may be nowhere near ready.

But more interesting, even after $viewContentLoaded fired, the element of interest still could not be found.

Only after the $timeout executed was it found. Note that even though the $timeout was a value of 0, nearly 200 milliseconds elapsed before it executed, indicating that this thread was held off for quite a while, presumably while the DOM had angular templates added on a main thread. The total time from the first $document.ready() to the last $timeout execution was nearly 500 milliseconds.

In one extraordinary case where the value of a component was set and then the text() value was changed later in the $timeout, the $timeout value had to be increased until it worked (even though the element could be found during the $timeout). Something async within the 3rd party component caused a value to take precedence over the text until sufficient time passed. Another possibility is $scope.$evalAsync, but was not tried.

I am still looking for that one event that tells me the DOM has completely settled down and can be manipulated so that all cases work. So far an arbitrary timeout value is necessary, meaning at best this is a kludge that may not work on a slow browser. I have not tried JQuery options like liveQuery and publish/subscribe which may work, but certainly aren't pure angular.

Don't forget the awesome

git fetch -p

which fetches and prunes all origins.

In Swift you would do it like this:

    label.lineBreakMode = NSLineBreakMode.ByWordWrapping
    label.numberOfLines = 0

(Note that the way the lineBreakMode constant works is different to in ObjC)

Checkout this thread, it has some useful information about exiting and tracebacks.

If you are more interested in just killing the program, try something like this (this will take the legs out from under the cleanup code as well):

if __name__ == '__main__':
    try:
        main()
    except KeyboardInterrupt:
        print('Interrupted')
        try:
            sys.exit(0)
        except SystemExit:
            os._exit(0)

In my case I had to set delaysContentTouches to true because the objects inside the scrollView were all capturing the touch events and handling themselves rather than letting the scrollView itself handle it.

You can use Git rebasing. For example, if you want to modify back to commit bbc643cd, run

$ git rebase bbc643cd^ --interactive

In the default editor, modify 'pick' to 'edit' in the line whose commit you want to modify. Make your changes and then stage them with

$ git add <filepattern>

Now you can use

$ git commit --amend

to modify the commit, and after that

$ git rebase --continue

to return back to the previous head commit.

Recently, I had a program batch processing files, I have certainly closed each file in the loop, but the error still there.

And later, I resolved this problem by garbage collect eagerly every hundreds of files:

int index;
while () {
    try {
        // do with outputStream...
    } finally {
        out.close();
    }
    if (index++ % 100 = 0)
        System.gc();
}

Don't :-

xyz = Blogs.objects.get(user_id=id)

Use:-

xyz = Blogs.objects.all().filter(user_id=id)

This work for me with sample PDO :

public function GetTableColumn() {      
$query  = $this->db->prepare("SHOW COLUMNS FROM `what_table` LIKE 'what_column'");  
try{            
    $query->execute();                                          
    if($query->fetchColumn()) { return 1; }else{ return 0; }
    }catch(PDOException $e){die($e->getMessage());}     
}

I think you can use hash of RSVP.

Something like as below :

    const mainPromise = () => {
        const promise1 = new Promise((resolve, reject) => {
            setTimeout(() => {
                console.log('first promise is completed');
                resolve({data: '123'});
            }, 2000);
        });

        const promise2 = new Promise((resolve, reject) => {
            setTimeout(() => {
                console.log('second promise is completed');
                resolve({data: '456'});
            }, 2000);
        });

        return new RSVP.hash({
              prom1: promise1,
              prom2: promise2
          });

    };


   mainPromise()
    .then(data => {
        console.log(data.prom1);
        console.log(data.prom2);
    });

Although you could certainly use the compareTo method on an Integer instance, it's not clear when reading the code, so you should probably avoid doing so.

Java allows you to use autoboxing (see http://java.sun.com/j2se/1.5.0/docs/guide/language/autoboxing.html) to compare directly with an int, so you can do:

if (count > 0) { }

And the Integer instance count gets automatically converted to an int for the comparison.

If you're having trouble understanding this, check out the link above, or imagine it's doing this:

if (count.intValue() > 0) { }

The .bashrc file is used for setting variables used by interactive login shells. If you want those environment variables available in Eclipse you need to put them in /etc/environment.

Without repeating the same thing in previous answers,
I'm writing this answer for the people who are looking to starting a new project and don't know which is the best framework to startup your project. If you are a beginner to this framework the best thing I prefer is Use spring boot(with STS /Spring Tool Suite). Because it helps a lot. Its do all configurations on its own. Additionally, use Hibernate with spring-boot as a database framework. With this combination, your application will be the best. I can guarantee that with my experiences.

Even this is one of the best frameworks for JEE(in present) this is gonna die in the near future. There are lightweight alternatives coming up. So keep updated with your experience don't stick to one particular framework. The best thing is being fluent in concepts, not in the frameworks.

Please set the request Content Type before you read the response stream;

 request.ContentType = "text/xml";

The correct way in .NET 4.0 is:

if (String.IsNullOrWhiteSpace(strSearch))

The String.IsNullOrWhiteSpace method used above is equivalent to:

if (strSearch == null || strSearch == String.Empty || strSearch.Trim().Length == 0) 
// String.Empty is the same as ""

Reference for IsNullOrWhiteSpace method

http://msdn.microsoft.com/en-us/library/system.string.isnullorwhitespace.aspx

Indicates whether a specified string is Nothing, empty, or consists only of white-space characters.

In earlier versions, you could do something like this:

if (String.IsNullOrEmpty(strSearch) || strSearch.Trim().Length == 0)

The String.IsNullOrEmpty method used above is equivalent to:

if (strSearch == null || strSearch == String.Empty)

Which means you still need to check for your "IsWhiteSpace" case with the .Trim().Length == 0 as per the example.

Reference for IsNullOrEmpty method

http://msdn.microsoft.com/en-us/library/system.string.isnullorempty.aspx

Indicates whether the specified string is Nothing or an Empty string.

Explanation:

You need to ensure strSearch (or any variable for that matter) is not null before you dereference it using the dot character (.) - i.e. before you do strSearch.SomeMethod() or strSearch.SomeProperty you need to check that strSearch != null.

In your example you want to make sure your string has a value, which means you want to ensure the string:

• Is not null
• Is not the empty string (String.Empty / "")
• Is not just whitespace

In the cases above, you must put the "Is it null?" case first, so it doesn't go on to check the other cases (and error) when the string is null.

You can use: Thread.currentThread().isAlive();. Returns true if this thread is alive; false otherwise.

You can find the most up to date answer for the value in your project just execute the

        // EDIT -- this example is not thread safe -- do not use in production code
        if (ImageFullPath1Changed != null && value != _backingField)
            ImageFullPath1Changed(this, new EventArgs(/*whatever*/);
    }
}                        

That said, I completely agree with Ryan. This scenario is precisely why INotifyPropertyChanged exists.

As an update to Scott Munro's answer:

• In C# 6.0 and VB.NET 14.0 (VS 2015), either Environment.ExitCode or Environment.Exit(exitCode) is required to return an non-zero code from a console application. Changing the return type of Main has no effect.
• In F# 4.0 (VS 2015), the return value of the main entry point is respected.

Partial solution: for a single string column tmp = df['A1'].fillna(''); isEmpty = tmp=='' gives boolean Series of True where there are empty strings or NaN values.

Pandas concat vs append vs join vs merge

• Concat gives the flexibility to join based on the axis( all rows or all columns)

• Append is the specific case(axis=0, join='outer') of concat

• Join is based on the indexes (set by set_index) on how variable =['left','right','inner','couter']

• Merge is based on any particular column each of the two dataframes, this columns are variables on like 'left_on', 'right_on', 'on'

Try this.

ALTER PROCEDURE [dbo].[sp_ClientNotes_update]
    @id uniqueidentifier,
    @ordering smallint = NULL,
    @title nvarchar(20) = NULL,
    @content text = NULL
AS
BEGIN
    SET NOCOUNT ON;
    UPDATE tbl_ClientNotes
    SET ordering=ISNULL(@ordering,ordering), 
        title=ISNULL(@title,title), 
        content=ISNULL(@content, content)
    WHERE id=@id
END

It might also be worth adding an extra part to the WHERE clause, if you use transactional replication then it will send another update to the subscriber if all are NULL, to prevent this.

WHERE id=@id AND (@ordering IS NOT NULL OR
                  @title IS NOT NULL OR
                  @content IS NOT NULL)

.then() is chainable and will wait for previous .then() to resolve.

.success() and .error() can be chained, but they will all fire at once (so not much point to that)

.success() and .error() are just nice for simple calls (easy makers):

$http.post('/getUser').success(function(user){ 
   ... 
})

so you don't have to type this:

$http.post('getUser').then(function(response){
  var user = response.data;
})

But generally i handler all errors with .catch():

$http.get(...)
    .then(function(response){ 
      // successHandler
      // do some stuff
      return $http.get('/somethingelse') // get more data
    })
    .then(anotherSuccessHandler)
    .catch(errorHandler)

If you need to support <= IE8 then write your .catch() and .finally() like this (reserved methods in IE):

    .then(successHandler)
    ['catch'](errorHandler)

Working Examples:

Here's something I wrote in more codey format to refresh my memory on how it all plays out with handling errors etc:

Working JSFiddle, hope that helps.

If you need non-sequential guids you can send the sys_guid() results through a hashing function (see https://stackoverflow.com/a/22534843/1462295 ). The idea is to keep whatever uniqueness is used from the original creation, and get something with more shuffled bits.

For instance:

LOWER(SUBSTR(STANDARD_HASH(SYS_GUID(), 'SHA1'), 0, 32))  

Example showing default sequential guid vs sending it through a hash:

SELECT LOWER(SYS_GUID()) AS OGUID FROM DUAL
UNION ALL
SELECT LOWER(SYS_GUID()) AS OGUID FROM DUAL
UNION ALL
SELECT LOWER(SYS_GUID()) AS OGUID FROM DUAL
UNION ALL
SELECT LOWER(SYS_GUID()) AS OGUID FROM DUAL
UNION ALL
SELECT LOWER(SUBSTR(STANDARD_HASH(SYS_GUID(), 'SHA1'), 0, 32)) AS OGUID FROM DUAL
UNION ALL
SELECT LOWER(SUBSTR(STANDARD_HASH(SYS_GUID(), 'SHA1'), 0, 32)) AS OGUID FROM DUAL
UNION ALL
SELECT LOWER(SUBSTR(STANDARD_HASH(SYS_GUID(), 'SHA1'), 0, 32)) AS OGUID FROM DUAL
UNION ALL
SELECT LOWER(SUBSTR(STANDARD_HASH(SYS_GUID(), 'SHA1'), 0, 32)) AS OGUID FROM DUAL

(This is the KISS answer.)

Let's say you have several .java files in the current directory:

$ ls -1 *.java
javaFileName1.java
javaFileName2.java

Let's say each of them have a main() method (so they are programs, not libs), then to compile them do:

javac *.java -d .

This will generate as many subfolders as "packages" the .java files are associated to. In my case all java files where inside under the same package name packageName, so only one folder was generated with that name, so to execute each of them:

java -cp . packageName.javaFileName1
java -cp . packageName.javaFileName2

The original code you suggest is the best way.

Matlab is extremely good at vectorized operations such as this, at least for large vectors.

The built-in norm function is very fast. Here are some timing results:

V = rand(10000000,1);
% Run once
tic; V1=V/norm(V); toc           % result:  0.228273s
tic; V2=V/sqrt(sum(V.*V)); toc   % result:  0.325161s
tic; V1=V/norm(V); toc           % result:  0.218892s

V1 is calculated a second time here just to make sure there are no important cache penalties on the first call.

Timing information here was produced with R2008a x64 on Windows.

EDIT:

Revised answer based on gnovice's suggestions (see comments). Matrix math (barely) wins:

clc; clear all;
V = rand(1024*1024*32,1);
N = 10;
tic; for i=1:N, V1 = V/norm(V);         end; toc % 6.3 s
tic; for i=1:N, V2 = V/sqrt(sum(V.*V)); end; toc % 9.3 s
tic; for i=1:N, V3 = V/sqrt(V'*V);      end; toc % 6.2 s ***
tic; for i=1:N, V4 = V/sqrt(sum(V.^2)); end; toc % 9.2 s
tic; for i=1:N, V1=V/norm(V);           end; toc % 6.4 s

IMHO, the difference between "norm(V)" and "sqrt(V'*V)" is small enough that for most programs, it's best to go with the one that's more clear. To me, "norm(V)" is clearer and easier to read, but "sqrt(V'*V)" is still idiomatic in Matlab.

After some fiddling with a script I came to this action. Copy and save it in a .bat file:

FOR /F "usebackq tokens=5" %%i IN (`netstat -aon ^| find "3306"`) DO taskkill /F /PID %%i

Change 'find "3306"' in the port number which needs to be free. Then run the file as administrator. It will kill all the processes running on this port.

Use below code:-

public class SergejAdapter extends RecyclerView.Adapter<SergejAdapter.MyViewHolder>{

...

class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{


    @Override
    public void onClick(View v) {
        // here you use position
        int position = getAdapterPosition();
        ...

    }
}
}

If you're using a functional component, you can define defaults in the destructuring assignment, like so:

export default ({ children, id="menu", side="left", image={menu} }) => {
  ...
};

One difference is for r+ if the files does not exist, it'll not be created and open fails. But in case of a+ the file will be created if it does not exist.

Sequence to be followed.

pip install mysqlclient
sudo apt-get install python3-dev libmysqlclient-dev
pip install configparser 
sudo cp /usr/lib/python3.6/configparser.py /usr/lib/python3.6/ConfigParser.py 

Then try to install the MYSQL-python again. That Worked for me

Method #1: CSS :focus pseudo-class

As pure CSS solution, you could achieve sort of the effect by using a tabindex attribute for the image, and :focus pseudo-class as follows:

<img class="crossRotate" src="http://placehold.it/100" tabindex="1" />

.crossRotate {
    outline: 0;
    /* other styles... */
}

.crossRotate:focus {
  -webkit-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  transform: rotate(45deg);
}

WORKING DEMO.

Note: Using this approach, the image gets rotated onclick (focused), to negate the rotation, you'll need to click somewhere out of the image (blured).

Method #2: Hidden input & :checked pseudo-class

This is one of my favorite methods. In this approach, there's a hidden checkbox input and a <label> element which wraps the image.

Once you click on the image, the hidden input is checked because of using for attribute for the label.

Hence by using the :checked pseudo-class and adjacent sibling selector +, we could get the image to be rotated:

<input type="checkbox" id="hacky-input">

<label for="hacky-input">
  <img class="crossRotate" src="http://placehold.it/100">
</label>

#hacky-input {
  display: none; /* Hide the input */
}

#hacky-input:checked + label img.crossRotate {
  -webkit-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  transform: rotate(45deg);
}

WORKING DEMO #1.

WORKING DEMO #2 (Applying the rotate to the label gives a better experience).

Method #3: Toggling a class via JavaScript

If using JavaScript/jQuery is an option, you could toggle a .active class by .toggleClass() to trigger the rotation effect, as follows:

$('.crossRotate').on('click', function(){
    $(this).toggleClass('active');
});

.crossRotate.active {
    /* vendor-prefixes here... */
    transform: rotate(45deg);
}

WORKING DEMO.

Here's my own implementation of singletons. All you have to do is decorate the class; to get the singleton, you then have to use the Instance method. Here's an example:

@Singleton
class Foo:
   def __init__(self):
       print 'Foo created'

f = Foo() # Error, this isn't how you get the instance of a singleton

f = Foo.instance() # Good. Being explicit is in line with the Python Zen
g = Foo.instance() # Returns already created instance

print f is g # True

And here's the code:

class Singleton:
    """
    A non-thread-safe helper class to ease implementing singletons.
    This should be used as a decorator -- not a metaclass -- to the
    class that should be a singleton.

    The decorated class can define one `__init__` function that
    takes only the `self` argument. Also, the decorated class cannot be
    inherited from. Other than that, there are no restrictions that apply
    to the decorated class.

    To get the singleton instance, use the `instance` method. Trying
    to use `__call__` will result in a `TypeError` being raised.

    """

    def __init__(self, decorated):
        self._decorated = decorated

    def instance(self):
        """
        Returns the singleton instance. Upon its first call, it creates a
        new instance of the decorated class and calls its `__init__` method.
        On all subsequent calls, the already created instance is returned.

        """
        try:
            return self._instance
        except AttributeError:
            self._instance = self._decorated()
            return self._instance

    def __call__(self):
        raise TypeError('Singletons must be accessed through `instance()`.')

    def __instancecheck__(self, inst):
        return isinstance(inst, self._decorated)

Don't overwrite the built-in Vim.

Instead, install it from source in a different location or via Homebrew or MacPorts in their default location then add this line to your .bashrc or .profile:

alias vim='/path/to/your/own/vim'

and/or change your $PATH so that it looks into its location before the default location.

The best thing to do, in my opinion, is to simply download the latest MacVim which comes with a very complete vim executable and use it in Terminal.app like so.

alias vim='/Applications/MacVim.app/Contents/MacOS/Vim' # or something like that, YMMV

Why and when you should mark the request parameter as implicit:

Some methods that you will make use of in the body of your action have an implicit parameter list like, for example, Form.scala defines a method:

def bindFromRequest()(implicit request: play.api.mvc.Request[_]): Form[T] = { ... }

You don't necessarily notice this as you would just call myForm.bindFromRequest() You don't have to provide the implicit arguments explicitly. No, you leave the compiler to look for any valid candidate object to pass in every time it comes across a method call that requires an instance of the request. Since you do have a request available, all you need to do is to mark it as implicit.

You explicitly mark it as available for implicit use.

You hint the compiler that it's "OK" to use the request object sent in by the Play framework (that we gave the name "request" but could have used just "r" or "req") wherever required, "on the sly".

myForm.bindFromRequest()

see it? it's not there, but it is there!

It just happens without your having to slot it in manually in every place it's needed (but you can pass it explicitly, if you so wish, no matter if it's marked implicit or not):

myForm.bindFromRequest()(request)

Without marking it as implicit, you would have to do the above. Marking it as implicit you don't have to.

When should you mark the request as implicit? You only really need to if you are making use of methods that declare an implicit parameter list expecting an instance of the Request. But to keep it simple, you could just get into the habit of marking the request implicit always. That way you can just write beautiful terse code.

You can use:

if (callback && typeof(callback) === "function") {
    callback();
}

The below example is little more comprehensive:

function mySandwich(param1, param2, callback) {_x000D_
  alert('Started eating my sandwich.\n\nIt has: ' + param1 + ', ' + param2);_x000D_
  var sandwich = {_x000D_
      toppings: [param1, param2]_x000D_
    },_x000D_
    madeCorrectly = (typeof(param1) === "string" && typeof(param2) === "string") ? true : false;_x000D_
  if (callback && typeof(callback) === "function") {_x000D_
    callback.apply(sandwich, [madeCorrectly]);_x000D_
  }_x000D_
}_x000D_
_x000D_
mySandwich('ham', 'cheese', function(correct) {_x000D_
  if (correct) {_x000D_
    alert("Finished eating my " + this.toppings[0] + " and " + this.toppings[1] + " sandwich.");_x000D_
  } else {_x000D_
    alert("Gross!  Why would I eat a " + this.toppings[0] + " and " + this.toppings[1] + " sandwich?");_x000D_
  }_x000D_
});

It's the same problem with managed and easy to use programming language as always - they are slow (and sometimes memory-eating).

These are languages to do control rather than processing. If I would have to write application to transform images and had to use Python too all the processing could be written in C++ and connected to Python via bindings while interface and process control would be definetely Python.

Rob R.'s answer was definitely the way to go. I tried copying the ic_launcher.png files from another project and Eclipse still wouldn't read them. Going through the manifest is much quicker and easier.

Assuming that you have a DHCP server running at your router I would use:

# /etc/network/interfaces
auto lo eth0
iface lo inet loopback

iface eth0 inet dhcp

After changing the file issue (as root):

/etc/init.d/networking restart

Note: This solution only works if your GridView columns are known ahead of time.

It sounds like you're using a GridView with AutoGenerateColumns=true, which is the default. I recommend setting AutoGenerateColumns=false and adding the columns manually:

<asp:GridView runat="server" ID="MyGridView"
    AutoGenerateColumns="false" DataSourceID="MySqlDataSource">
    <Columns>
        <asp:BoundField DataField="Column1" />
        <asp:BoundField DataField="Column2" />
        <asp:BoundField DataField="Column3" />
    </Columns>
</asp:GridView>

And only include a BoundField for each field that you want to be displayed. This will give you the most flexibility in terms of how the data gets displayed.

Since the column may be null in the database, the rs.getString() will throw a NullPointerException()

No.

rs.getString will not throw NullPointer if the column is present in the selected result set (SELECT query columns) For a particular record if value for the 'comumn is null in db, you must do something like this -

String myValue = rs.getString("myColumn");
if (rs.wasNull()) {
    myValue = ""; // set it to empty string as you desire.
}

You may want to refer to wasNull() documentation -

From java.sql.ResultSet
boolean wasNull() throws SQLException;

* Reports whether
* the last column read had a value of SQL <code>NULL</code>.
* Note that you must first call one of the getter methods
* on a column to try to read its value and then call
* the method <code>wasNull</code> to see if the value read was
* SQL <code>NULL</code>.
*
* @return <code>true</code> if the last column value read was SQL
*         <code>NULL</code> and <code>false</code> otherwise
* @exception SQLException if a database access error occurs or this method is 
*            called on a closed result set
*/

If that is all you have changed, you may not have the mysqli driver installed or enabled within your PHP configuration.

Check for its presence using phpinfo(), or in your php.ini file (extension=php_mysqli....).

You could also do

   var x = $('#element').height();   // or any changing value

   $('selector').css({'top' : x + 'px'});

OR

You can use directly

$('#element').css( "height" )

The difference between .css( "height" ) and .height() is that the latter returns a unit-less pixel value (for example, 400) while the former returns a value with units intact (for example, 400px). The .height() method is recommended when an element's height needs to be used in a mathematical calculation. jquery doc

According to the subprocess.check_output() docs, the exception raised on error has an output attribute that you can use to access the error details:

try:
    subprocess.check_output(...)
except subprocess.CalledProcessError as e:
    print(e.output)

You should then be able to analyse this string and parse the error details with the json module:

if e.output.startswith('error: {'):
    error = json.loads(e.output[7:]) # Skip "error: "
    print(error['code'])
    print(error['message'])

Use itertools.combinations(mylist, 2)

mylist = range(5)
for x,y in itertools.combinations(mylist, 2):
    print x,y

0 1
0 2
0 3
0 4
1 2
1 3
1 4
2 3
2 4
3 4

You must sort your data according your needs (es. in reverse order) and use select top query

You should form the command with the contents of the textboxes:

sql = "insert into Main (Firt Name, Last Name) values(" + textbox2.Text + 
"," + textbox3.Text+ ")";

This, of course, provided that you manage to open the connection correctly.

It would be helpful to know what is happening with your current code. If you are getting some error displayed in that message box, it would be great to know what it's saying.

You should also validate the inputs before actually running the command (i.e. make sure they don't contain malicious code).

You can use the react-moment package

-> https://www.npmjs.com/package/react-moment

Put in your file the next line:

import moment from "moment";

date_create: moment().format("DD-MM-YYYY hh:mm:ss")

You can disable them altogether by

(setq make-backup-files nil)

I can think of a cheeky way to do it, I don't think this will be the best option but it will work.

Create the header as a separate table then place the other in a div and set a max size, then allow the scroll to come in by using overflow.

table {_x000D_
  width: 500px;_x000D_
}_x000D_
_x000D_
.scroll {_x000D_
  max-height: 60px;_x000D_
  overflow: auto;_x000D_
}

<table border="1">_x000D_
  <tr>_x000D_
  <th>head1</th>_x000D_
  <th>head2</th>_x000D_
  <th>head3</th>_x000D_
  <th>head4</th>_x000D_
  </tr>_x000D_
</table>_x000D_
<div class="scroll">_x000D_
  <table>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>More Text</td><td>More Text</td><td>More Text</td><td>More Text</td></tr>_x000D_
    <tr><td>Text Text</td><td>Text Text</td><td>Text Text</td><td>Text Text</td></tr>_x000D_
    <tr><td>Even More Text Text</td><td>Even More Text Text</td><td>Even More Text Text</td><td>Even More Text Text</td></tr>_x000D_
  </table>_x000D_
</div>

It would probably be easiest to implement this using JavaScript ... Here's a JQuery script to demo ... As the others mentioned ... we have a class named 'active' to indicate the active tab - NOT the pseudo-class ':active.' We could have just as easily named it anything though ... selected, current, etc., etc.

/* CSS */

#nav { width:480px;margin:1em auto;}

#nav ul {margin:1em auto; padding:0; font:1em "Arial Black",sans-serif; }

#nav ul li{display:inline;} 

#nav ul li a{text-decoration:none; margin:0; padding:.25em 25px; background:#666; color:#ffffff;} 

#nav ul li a:hover{background:#ff9900; color:#ffffff;} 

#nav ul li a.active {background:#ff9900; color:#ffffff;} 

/* JQuery Example */

<script type="text/javascript">
$(function (){

    $('#nav ul li a').each(function(){
        var path = window.location.href;
        var current = path.substring(path.lastIndexOf('/')+1);
        var url = $(this).attr('href');

        if(url == current){
            $(this).addClass('active');
        };
    });         
});

</script>

 /* HTML */

<div id="nav" >
    <ul>
        <li><a href='index.php?1'>One</a></li>
        <li><a href='index.php?2'>Two</a></li>
        <li><a href='index.php?3'>Three</a></li>
        <li><a href='index.php?4'>Four</a></li>
    </ul>
</div>

Make sure the test class is in a sub-package of your main spring boot class

Here you are. Set source of ImageView statically in xml or dynamically in code.
