Run it every three days...

0 0 */3 * *

How about that?

If you want it to run on specific days of the month, like the 1st, 4th, 7th, etc... then you can just have a conditional in your script that checks for the current day of the month.

if (((date('j') - 1) % 3))
   exit();

or, as @mario points out, you can use date('k') to get the day of the year instead of doing it based on the day of the month.

I ran into similar problem a while back and what was happening in my case was the outer recycler view was working perfectly fine but the the adapter of inner/second recycler view had minor issues all the methods like constructor got initiated and even getCount() method was being called, although the final methods responsible to generate view ie..

1. onBindViewHolder() methods never got called. --> Problem 1.

2. When it got called finally it never show the list items/rows of recycler view. --> Problem 2.

Reason why this happened :: When you put a recycler view inside another recycler view, then height of the first/outer recycler view is not auto adjusted. It is defined when the first/outer view is created and then it remains fixed. At that point your second/inner recycler view has not yet loaded its items and thus its height is set as zero and never changes even when it gets data. Then when onBindViewHolder() in your second/inner recycler view is called, it gets items but it doesn't have the space to show them because its height is still zero. So the items in the second recycler view are never shown even when the onBindViewHolder() has added them to it.

Solution :: you have to create your custom LinearLayoutManager for the second recycler view and that is it. To create your own LinearLayoutManager: Create a Java class with the name CustomLinearLayoutManager and paste the code below into it. NO CHANGES REQUIRED

public class CustomLinearLayoutManager extends LinearLayoutManager {

    private static final String TAG = CustomLinearLayoutManager.class.getSimpleName();

    public CustomLinearLayoutManager(Context context) {
        super(context);

    }

    public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
        super(context, orientation, reverseLayout);
    }

    private int[] mMeasuredDimension = new int[2];

    @Override
    public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state, int widthSpec, int heightSpec) {

        final int widthMode = View.MeasureSpec.getMode(widthSpec);
        final int heightMode = View.MeasureSpec.getMode(heightSpec);
        final int widthSize = View.MeasureSpec.getSize(widthSpec);
        final int heightSize = View.MeasureSpec.getSize(heightSpec);

        int width = 0;
        int height = 0;
        for (int i = 0; i < getItemCount(); i++) {
            measureScrapChild(recycler, i, View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                    View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
                    mMeasuredDimension);


            if (getOrientation() == HORIZONTAL) {
                width = width + mMeasuredDimension[0];
                if (i == 0) {
                    height = mMeasuredDimension[1];
                }
            } else {
                height = height + mMeasuredDimension[1];
                if (i == 0) {
                    width = mMeasuredDimension[0];
                }
            }
        }
        switch (widthMode) {
            case View.MeasureSpec.EXACTLY:
                width = widthSize;
            case View.MeasureSpec.AT_MOST:
            case View.MeasureSpec.UNSPECIFIED:
        }

        switch (heightMode) {
            case View.MeasureSpec.EXACTLY:
                height = heightSize;
            case View.MeasureSpec.AT_MOST:
            case View.MeasureSpec.UNSPECIFIED:
        }

        setMeasuredDimension(width, height);
    }

    private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
                                   int heightSpec, int[] measuredDimension) {
        try {
            View view = recycler.getViewForPosition(position);

            if (view != null) {
                RecyclerView.LayoutParams p = (RecyclerView.LayoutParams) view.getLayoutParams();

                int childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec,
                        getPaddingLeft() + getPaddingRight(), p.width);

                int childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec,
                        getPaddingTop() + getPaddingBottom(), p.height);

                view.measure(childWidthSpec, childHeightSpec);
                measuredDimension[0] = view.getMeasuredWidth() + p.leftMargin + p.rightMargin;
                measuredDimension[1] = view.getMeasuredHeight() + p.bottomMargin + p.topMargin;
                recycler.recycleView(view);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

This is another example using defined column/table names.

Chromedriver is a WebDriver. WebDriver is an open-source tool for automated testing of web apps across many browsers. It provides capabilities for navigating to web pages, user input, JavaScript execution, and more. When you run this driver, it will enable your scripts to access this and run commands on Google Chrome.

This can be done via scripts running in the local network (Only local connections are allowed.) or via scripts running on outside networks (All remote connections are allowed.). It is always safer to use the Local Connection option. By default your Chromedriver is accessible via port 9515.

To answer the question, it is just an informational message. You don't have to worry about it.

Given below are both options.

$ chromedriver

public int GetNthOccurrenceOfChar(string s, char c, int occ)
{
    return String.Join(c.ToString(), s.Split(new char[] { c }, StringSplitOptions.None).Take(occ)).Length;
}

To remove ALL event-handlers, this is what worked for me:

To remove all event handlers mean to have the plain HTML structure without all the event handlers attached to the element and its child nodes. To do this, jQuery's clone() helped.

var original, clone;
// element with id my-div and its child nodes have some event-handlers
original = $('#my-div');
clone = original.clone();
//
original.replaceWith(clone);

With this, we'll have the clone in place of the original with no event-handlers on it.

Good Luck...

I just need one line to show a website in my app:

startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://match4app.com")));

<?php
    if (!preg_match("/^(http|ftp):/", $_POST['url'])) {
        $_POST['url'] = 'http://'.$_POST['url'];
    }
    $url = $_POST['url'];
?>

This code will add http:// to the URL if it’s not there.

I was experiencing a similar error message that I noticed in the Windows Event Viewer that read:

Login failed for user 'NT AUTHORITY\NETWORK SERVICE'. Reason: Failed to open the explicitly specified database. [CLIENT: local machine]

The solution that resolved my problem was:

1. Login to SqlExpress via SQL Server Management Studio
2. Go to the "Security" directory of the database
3. Right-click the Users directory
4. Select "New User..."
5. Add 'NT AUTHORITY\NETWORK SERVICE' as a new user
6. In the Data Role Membership area, select db_owner
7. Click OK

Here's a screenshot of the above:

You can use SimpleDateFormat to do it. You just have to know 2 things.

1. All dates are internally represented in UTC
2. .getTime() returns the number of milliseconds since 1970-01-01 00:00:00 UTC.

package se.wederbrand.milliseconds;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;

public class Main {        
    public static void main(String[] args) throws Exception {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
        sdf.setTimeZone(TimeZone.getTimeZone("UTC"));

        String inputString = "00:01:30.500";

        Date date = sdf.parse("1970-01-01 " + inputString);
        System.out.println("in milliseconds: " + date.getTime());        
    }
}

If you're rolling your own modules specific to your application, you can either:

• Keep those (and only those) in your application's /node_modules folder and move out all the other dependencies to parent ../node_modules folder. This will work because of how NodeJS CommonJS modules system works by moving up to the parent directory, and so on, until the root of the tree is reached. See: https://nodejs.org/api/modules.html

• Or gitignore all /node_modules/* except your /node_modules/your-modules. See: Make .gitignore ignore everything except a few files

This use case is pretty awesome. It lets you keep modules you created specifically for your application nicely with it and doesn't clutter with dependencies which can be installed later.

The following code will disable cut, copy and paste from full page.

$(document).ready(function () {
   $('body').bind('cut copy paste', function (e) {
      e.preventDefault();
   });
});

Here's the code for server side firebase cloud request from C# / Asp.net.
Please note that your client side should have same topic.
e.g.

FirebaseMessaging.getInstance().subscribeToTopic("news");

public String SendNotificationFromFirebaseCloud()
{
    var result = "-1";
    var webAddr = "https://fcm.googleapis.com/fcm/send";

    var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
    httpWebRequest.ContentType = "application/json";
    httpWebRequest.Headers.Add("Authorization:key=" + YOUR_FIREBASE_SERVER_KEY);
    httpWebRequest.Method = "POST";

    using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
    {
        string json = "{\"to\": \"/topics/news\",\"data\": {\"message\": \"This is a Firebase Cloud Messaging Topic Message!\",}}";


        streamWriter.Write(json);
        streamWriter.Flush();
    }

    var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
    using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
    {
        result = streamReader.ReadToEnd();
    }

    return result;
}

I have just completed a android App about wsdl,i have some tips to append:

1.the most important resource is www.wsdl2code.com

2.you can take you username and password with header, which encoded with Base64,such as :

        String USERNAME = "yourUsername";
    String PASSWORD = "yourPassWord";
    StringBuffer auth = new StringBuffer(USERNAME);
    auth.append(':').append(PASSWORD);
    byte[] raw = auth.toString().getBytes();
    auth.setLength(0);
    auth.append("Basic ");
    org.kobjects.base64.Base64.encode(raw, 0, raw.length, auth);
    List<HeaderProperty> headers = new ArrayList<HeaderProperty>();
    headers.add(new HeaderProperty("Authorization", auth.toString())); // "Basic V1M6"));

    Vectordianzhan response = bydWs.getDianzhans(headers);

3.somethimes,you are not sure either ANDROID code or webserver is wrong, then debug is important.in the sample , catching "XmlPullParserException" ,log "requestDump" and "responseDump"in the exception.additionally, you should catch the IP package with adb.

    try {
    Logg.i(TAG, "2  ");
    Object response = androidHttpTransport.call(SOAP_ACTION, envelope, headers); 
    Logg.i(TAG, "requestDump: " + androidHttpTransport.requestDump);
    Logg.i(TAG, "responseDump: "+ androidHttpTransport.responseDump);
    Logg.i(TAG, "3");
} catch (IOException e) {
    Logg.i(TAG, "IOException");
} 
catch (XmlPullParserException e) {
     Logg.i(TAG, "requestDump: " + androidHttpTransport.requestDump);
     Logg.i(TAG, "responseDump: "+ androidHttpTransport.responseDump);
     Logg.i(TAG, "XmlPullParserException");
     e.printStackTrace();
}

I prefer the immutable version

foo = {
    1:1,
    2:2,
    3:3
}
removeKeys = [1,2]
def woKeys(dct, keyIter):
    return {
        k:v
        for k,v in dct.items() if k not in keyIter
    }

>>> print(woKeys(foo, removeKeys))
{3: 3}
>>> print(foo)
{1: 1, 2: 2, 3: 3}

You're storing the .Text properties of the textboxes directly into the database, this doesn't work. The .Text properties are Strings (i.e. simple text) and not typed as DateTime instances. Do the conversion first, then it will work.

Do this for each date parameter:

Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) ) 

Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse or DateTime.TryParseExact, but implementing that is an exercise for the reader.

This same issue happened to me when I had more than one API function in the module and tried to wrap each function with 2 decorators:

1. @app.route()
2. My custom @exception_handler decorator

I got this same exception because I tried to wrap more than one function with those two decorators:

@app.route("/path1")
@exception_handler
def func1():
    pass

@app.route("/path2")
@exception_handler
def func2():
    pass

Specifically, it is caused by trying to register a few functions with the name wrapper:

def exception_handler(func):
  def wrapper(*args, **kwargs):
    try:
        return func(*args, **kwargs)
    except Exception as e:
        error_code = getattr(e, "code", 500)
        logger.exception("Service exception: %s", e)
        r = dict_to_json({"message": e.message, "matches": e.message, "error_code": error_code})
        return Response(r, status=error_code, mimetype='application/json')
  return wrapper

Changing the name of the function solved it for me (wrapper.__name__ = func.__name__):

def exception_handler(func):
  def wrapper(*args, **kwargs):
    try:
        return func(*args, **kwargs)
    except Exception as e:
        error_code = getattr(e, "code", 500)
        logger.exception("Service exception: %s", e)
        r = dict_to_json({"message": e.message, "matches": e.message, "error_code": error_code})
        return Response(r, status=error_code, mimetype='application/json')
  # Renaming the function name:
  wrapper.__name__ = func.__name__
  return wrapper

Then, decorating more than one endpoint worked.

The accepted answer is best, but since there's more than one way to do it, here's another solution:

if [ "$string" != "${string/foo/}" ]; then
    echo "It's there!"
fi

${var/search/replace} is $var with the first instance of search replaced by replace, if it is found (it doesn't change $var). If you try to replace foo by nothing, and the string has changed, then obviously foo was found.

Note: The below answer is out of date since the Chrome disk cache format has changed.

Joachim Metz provides some documentation of the Chrome cache file format with references to further information.

For my use case, I only needed a list of cached URLs and their respective timestamps. I wrote a Python script to get these by parsing the data_* files under C:\Users\me\AppData\Local\Google\Chrome\User Data\Default\Cache\:

import datetime
with open('data_1', 'rb') as datafile:
    data = datafile.read()

for ptr in range(len(data)):
    fourBytes = data[ptr : ptr + 4]
    if fourBytes == b'http':

        # Found the string 'http'. Hopefully this is a Cache Entry
        endUrl = data.index(b'\x00', ptr)
        urlBytes = data[ptr : endUrl]
        try:
            url = urlBytes.decode('utf-8')
        except:
            continue

        # Extract the corresponding timestamp
        try:
            timeBytes = data[ptr - 72 : ptr - 64]
            timeInt = int.from_bytes(timeBytes, byteorder='little')
            secondsSince1601 = timeInt / 1000000
            jan1601 = datetime.datetime(1601, 1, 1, 0, 0, 0)
            timeStamp = jan1601 + datetime.timedelta(seconds=secondsSince1601)
        except:
            continue

        print('{} {}'.format(str(timeStamp)[:19], url))

Assuming the items override ToString appropriately:

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

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

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

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

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

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

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

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

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

I find using the pipe character with some top and bottom padding works well. Using a div with a border will require more CSS to vertically align it and get the horizontal spacing even with the other elements.

CSS

.divider-vertical {
    padding-top: 14px;
    padding-bottom: 14px;
}

HTML

<ul class="nav navbar-nav">
    <li class="active"><a href="#">Home</a></li>
    <li class="divider-vertical">&#124;</li>
    <li><a href="#">Faq</a></li>
    <li class="divider-vertical">&#124;</li>
    <li><a href="#">News</a></li>
    <li class="divider-vertical">&#124;</li>
    <li><a href="#">Contact</a></li>
</ul>

Hope this helps.

On top of @kp's answer:

I'm dealing with this and in my case, I have to show a child element and correct the height of the parent object accordingly (auto-sizing is not working in a bootstrap header for some reason I don't have time to debug).

But instead of using javascript to modify the parent, I think I'll dynamically add a CSS class to the parent and CSS-selectively show the children accordingly. This will maintain the decisions in the logic and not based on a CSS state.

tl;dr; apply the a and b styles to the parent <div>, not the child (of course, not everyone will be able to do this. i.e. Angular components making decisions of their own).

<style>
  .parent            { height: 50px; }
  .parent div        { display: none; }
  .with-children     { height: 100px; }
  .with-children div { display: block; }
</style>

<div class="parent">
  <div>child</div>
</div>

<script>
  // to show the children
  $('.parent').addClass('with-children');
</script>

I was almost using the same technology as you did, however I was using my app to connect an Exchange Server via Office 365 platform on WinForms. I too had the same issue as you did, but was able to accomplish by using code which has slight modification of what others have given above.

SmtpClient client = new SmtpClient(exchangeServer, 587);
client.Credentials = new System.Net.NetworkCredential(username, password);
client.EnableSsl = true;
client.Send(msg);

I had to use the Port 587, which is of course the default port over TSL and the did the authentication.

No. Go to database tools (for 2007) and click checkmark on the Message Bar. Then, after the message bar apears, click on Options, and then Enable. Hope this helps.

What you need to do is to call pthread_mutex_lock to secure a mutex, like this:

pthread_mutex_lock(&mutex);

Once you do this, any other calls to pthread_mutex_lock(mutex) will not return until you call pthread_mutex_unlock in this thread. So if you try to call pthread_create, you will be able to create a new thread, and that thread will be able to (incorrectly) use the shared resource. You should call pthread_mutex_lock from within your fooAPI function, and that will cause the function to wait until the shared resource is available.

So you would have something like this:

#include <pthread.h>
#include <stdio.h>

int sharedResource = 0;
pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER;

void* fooAPI(void* param)
{
    pthread_mutex_lock(&mutex);
    printf("Changing the shared resource now.\n");
    sharedResource = 42;
    pthread_mutex_unlock(&mutex);
    return 0;
}

int main()
{
    pthread_t thread;

    // Really not locking for any reason other than to make the point.
    pthread_mutex_lock(&mutex);
    pthread_create(&thread, NULL, fooAPI, NULL);
    sleep(1);
    pthread_mutex_unlock(&mutex);

    // Now we need to lock to use the shared resource.
    pthread_mutex_lock(&mutex);
    printf("%d\n", sharedResource);
    pthread_mutex_unlock(&mutex);
}

Edit: Using resources across processes follows this same basic approach, but you need to map the memory into your other process. Here's an example using shmem:

#include <stdio.h>
#include <unistd.h>
#include <sys/file.h>
#include <sys/mman.h>
#include <sys/wait.h>

struct shared {
    pthread_mutex_t mutex;
    int sharedResource;
};

int main()
{
    int fd = shm_open("/foo", O_CREAT | O_TRUNC | O_RDWR, 0600);
    ftruncate(fd, sizeof(struct shared));

    struct shared *p = (struct shared*)mmap(0, sizeof(struct shared),
        PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0);

    p->sharedResource = 0;

    // Make sure it can be shared across processes
    pthread_mutexattr_t shared;
    pthread_mutexattr_init(&shared);
    pthread_mutexattr_setpshared(&shared, PTHREAD_PROCESS_SHARED);

    pthread_mutex_init(&(p->mutex), &shared);

    int i;
    for (i = 0; i < 100; i++) {
        pthread_mutex_lock(&(p->mutex));
        printf("%d\n", p->sharedResource);
        pthread_mutex_unlock(&(p->mutex));
        sleep(1);
    }

    munmap(p, sizeof(struct shared*));
    shm_unlink("/foo");
}

Writing the program to make changes to p->sharedResource is left as an exercise for the reader. :-)

Forgot to note, by the way, that the mutex has to have the PTHREAD_PROCESS_SHARED attribute set, so that pthreads will work across processes.

I found this link while looking for something slightly different, how to start appending array objects to an empty numpy array, but tried all the solutions on this page to no avail.

Then I found this question and answer: How to add a new row to an empty numpy array

The gist here:

The way to "start" the array that you want is:

arr = np.empty((0,3), int)

Then you can use concatenate to add rows like so:

arr = np.concatenate( ( arr, [[x, y, z]] ) , axis=0)

See also https://docs.scipy.org/doc/numpy/reference/generated/numpy.concatenate.html

I got the same problem. I used a third-part library. When I compile this library, the compiler (gcc/clang) will complain about unused variables.

Like this

test.cpp:29:11: warning: variable 'magic' set but not used [-Wunused-but-set-variable] short magic[] = {

test.cpp:84:17: warning: unused variable 'before_write' [-Wunused-variable] int64_t before_write = Thread::currentTimeMillis();

So the solution is pretty clear. Adding -Wno-unused as gcc/clang CFLAG will suppress all "unused" warnings, even thought you have -Wall set.

In this way, you DO NOT NEED to change any code.

In case the data is not in the same character set you might consider this snippet from http://dev.mysql.com/doc/refman/5.0/en/charset-conversion.html

If the column has a nonbinary data type (CHAR, VARCHAR, TEXT), its contents should be encoded in the column character set, not some other character set. If the contents are encoded in a different character set, you can convert the column to use a binary data type first, and then to a nonbinary column with the desired character set.

Here is an example:

 ALTER TABLE t1 CHANGE c1 c1 BLOB;
 ALTER TABLE t1 CHANGE c1 c1 VARCHAR(100) CHARACTER SET utf8;

Make sure to choose the right collation, or you might get unique key conflicts. e.g. Éleanore and Eleanore might be considered the same in some collations.

Aside:

I had a situation where certain characters "broke" in emails even though they were stored as UTF-8 in the database. If you are sending emails using utf8 data, you might want to also convert your emails to send in UTF8.

In PHPMailer, just update this line: public $CharSet = 'utf-8';

If you are looking inside dockerfile while creating image, add this line:

RUN apk add --update yourPackageName

You need to use the group(int) of your matcher - group(0) is the entire match, and group(1) is the first group you marked. In the example you specify, group(1) is what comes after "sentence".

Android Activity objects can be destroyed and reconstituted. So, you will need to use another approach to look them - or any object they create!!! - up. That is, you could pass as static class reference but then the object handle (Java calls these "references", as does SmallTalk; but they are not references in the sense of C or assembly) will be possibly invalid later because a "feature" of Android OE is any Activity can be annihilated and reconstituted later.

The original question asked "How to pass object from one activity to another in Android" and nobody has answered that. For sure, you can serialized (Serializable, Parcelable, to/from JSON) and pass a copy of the object's data and a new object having the same data could be created; but it will NOT have the same references/handles. Also, many others mentioned you can store the reference in a static store. And that will work unless Android decides to onDestroy your Activity.

So, to really solve the original question you would need a static lookup plus each object will update its reference when/if it is recreated. E.g. each Android Activity would relist itself if its onCreate is called. You can also see how some people use the task list to search out an Activity by name. (system is temporarily destroying this instance of the activity to save space..getRunningTasks, the task list is effectively a specialized listing of the most recent object instance of each Activity).

For reference:

Stopped: "The activity is completely obscured by another activity (the activity is now in the "background"). A stopped activity is also still alive (the Activity object is retained in memory, it maintains all state and member information, but is not attached to the window manager). However, it is no longer visible to the user and it can be killed by the system when memory is needed elsewhere."

onDestroy "system is temporarily destroying this instance of the activity to save space."

So, the Message Bus is a workable solution. It basically "punts". Rather than try to have references to objects; then you re-architect your design to use MessagePassing instead of SequentialCode. Exponentially harder to debug; but it lets you ignore these sort of OperatingEnvironment understandings. Effectively, each object method access is inverted so the caller posts a Message and the object itself defines a handler for that message. Lots more code but can make it robust with the Android OE restrictions.

If all you want is the top Activity (typical thing in Android apps due to "Context" being needed everywhere), then you can just have each Activity lists itself as "top" in the static global space whenever its onResume is called. Then your AlertDialog or whatever which needs a context can just grab it from there. Also, its a bit yucky to use a global but can simplifying passing a Context up and down everywhere and, for sure, when you use a MessageBus then IT IS global anyways.

You can use the following code which is given below;

Collections.sort(list, Collections.reverseOrder());

or if you are going to use custom comparator you can use as it is given below

Collections.sort(list, Collections.reverseOrder(new CustomComparator());

Where CustomComparator is a comparator class that compares the object which is present in the list.

If, for example, x = 5 and is stored as string, you can also just:

x = x + 0

and the new x would be stored as a numeric value.

in your shell script (or .bashrc) you may use somthing like:

umask 022

umask is a command that determines the settings of a mask that controls how file permissions are set for newly created files.

I had this issue also and I simply found out that if you simply remove the "#" the issue goes off. Like this :

<a href="" class="disabled" ng-click="doSomething(object)">Do something</a>

[] denotes a list, () denotes a tuple and {} denotes a dictionary. You should take a look at the official Python tutorial as these are the very basics of programming in Python.

What you have is a list of strings. You can sort it like this:

In [1]: lst = ['Stem', 'constitute', 'Sedge', 'Eflux', 'Whim', 'Intrigue']

In [2]: sorted(lst)
Out[2]: ['Eflux', 'Intrigue', 'Sedge', 'Stem', 'Whim', 'constitute']

As you can see, words that start with an uppercase letter get preference over those starting with a lowercase letter. If you want to sort them independently, do this:

In [4]: sorted(lst, key=str.lower)
Out[4]: ['constitute', 'Eflux', 'Intrigue', 'Sedge', 'Stem', 'Whim']

You can also sort the list in reverse order by doing this:

In [12]: sorted(lst, reverse=True)
Out[12]: ['constitute', 'Whim', 'Stem', 'Sedge', 'Intrigue', 'Eflux']

In [13]: sorted(lst, key=str.lower, reverse=True)
Out[13]: ['Whim', 'Stem', 'Sedge', 'Intrigue', 'Eflux', 'constitute']

Please note: If you work with Python 3, then str is the correct data type for every string that contains human-readable text. However, if you still need to work with Python 2, then you might deal with unicode strings which have the data type unicode in Python 2, and not str. In such a case, if you have a list of unicode strings, you must write key=unicode.lower instead of key=str.lower.

if not exist "%USERPROFILE%\.qgis-custom\" (
    mkdir "%USERPROFILE%\.qgis-custom" 2>nul
    if not errorlevel 1 (
        xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
    )
)

You have it almost done. The logic is correct, just some little changes.

This code checks for the existence of the folder (see the ending backslash, just to differentiate a folder from a file with the same name).

If it does not exist then it is created and creation status is checked. If a file with the same name exists or you have no rights to create the folder, it will fail.

If everyting is ok, files are copied.

All paths are quoted to avoid problems with spaces.

It can be simplified (just less code, it does not mean it is better). Another option is to always try to create the folder. If there are no errors, then copy the files

mkdir "%USERPROFILE%\.qgis-custom" 2>nul 
if not errorlevel 1 (
    xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e
)

In both code samples, files are not copied if the folder is not being created during the script execution.

EDITED - As dbenham comments, the same code can be written as a single line

md "%USERPROFILE%\.qgis-custom" 2>nul && xcopy "%OSGEO4W_ROOT%\qgisconfig" "%USERPROFILE%\.qgis-custom" /s /v /e

The code after the && will only be executed if the previous command does not set errorlevel. If mkdir fails, xcopy is not executed.

methods for setting attributes(for example class) on an element: 1. el.className = string 2. el.setAttribute('class',string) 3. el.attributes.setNamedItem(object) 4. el.setAttributeNode(node)

I have made a simple benchmark test (here)

and it seems that setAttributeNode is about 3 times faster then using setAttribute.

so if performance is an issue - use "setAttributeNode"

I always use the time-stamp - so its not possible, that the file exists already:

import shutil
import datetime

now = str(datetime.datetime.now())[:19]
now = now.replace(":","_")

To pass arguments to your python script while running a script via command line

python create_thumbnail.py test1.jpg test2.jpg

here, script name - create_thumbnail.py, argument 1 - test1.jpg, argument 2 - test2.jpg

With in the create_thumbnail.py script i use

sys.argv[1:]

which give me the list of arguments i passed in command line as ['test1.jpg', 'test2.jpg']

Googling gives me this:

Command A & Command B

Execute Command A, then execute Command B (no evaluation of anything)

Command A | Command B

Execute Command A, and redirect all its output into the input of Command B

Command A && Command B

Execute Command A, evaluate the errorlevel after running and if the exit code (errorlevel) is 0, only then execute Command B

Command A || Command B

Execute Command A, evaluate the exit code of this command and if it's anything but 0, only then execute Command B

_{Both the two most upvoted answers are wrong. It should have nothing to do with "store different/multiple languages". You can support Spanish characters like ñ and English, with just common varchar field and Latin1_General_CI_AS COLLATION, e.g.}

Short Version
You should use NVARCHAR/NCHAR whenever the ENCODING, which is determined by COLLATION of the field, doesn't support the characters needed.
Also, depending on the SQL Server version, you can use specific COLLATIONs, like Latin1_General_100_CI_AS_SC_UTF8 which is available since SQL Server 2019. Setting this collation on a VARCHAR field (or entire table/database), will use UTF-8 ENCODING for storing and handling the data on that field, allowing fully support UNICODE characters, and hence any languages embraced by it.

To FULLY UNDERSTAND:
_{To fully understand what I'm about to explain, it's mandatory to have the concepts of UNICODE, ENCODING and COLLATION all extremely clear in your head. If you don't, then first take a look below at my humble and simplified explanation on "What is UNICODE, ENCODING, COLLATION and UTF-8, and how they are related" section and supplied documentation links. Also, everything I say here is specific to Microsoft SQL Server, and how it stores and handles data in char/nchar and varchar/nvarchar fields.}

Let's say we wanna store a peculiar text on our MSSQL Server database. It could be an Instagram comment as "I love stackoverflow! ".
The plain English part would be perfectly supported even by ASCII, but since there are also an emoji, which is a character specified in the UNICODE standard, we need an ENCODING that supports this Unicode character.

MSSQL Server uses the COLLATION to determine what ENCODING is used on char/nchar/varchar/nvarchar fields. So, differently than a lot think, COLLATION is not only about sorting and comparing data, but also about ENCODING, and by consequence: how our data will be stored!

So, HOW WE KNOW WHAT IS THE ENCODING USED BY OUR COLLATION? With this:

SELECT COLLATIONPROPERTY( 'Latin1_General_CI_AI' , 'CodePage' ) AS [CodePage]
--returns 1252

This simple SQL returns the Windows Code Page for a COLLATION. A Windows Code Page is nothing more than another mapping to ENCODINGs. For the Latin1_General_CI_AI COLLATION it returns the Windows Code Page code 1252 , that maps to Windows-1252 ENCODING.
So, for a varchar column, with Latin1_General_CI_AI COLLATION, this field will handle its data using the Windows-1252 ENCODING, and only correctly store characters supported by this encoding.

If we check the Windows-1252 ENCODING specification Character List for Windows-1252, we will find out that this encoding won't support our emoji character. And if we still try it out:

OK, SO HOW CAN WE SOLVE THIS?? Actually, it depends, and that is GOOD!

NCHAR/NVARCHAR

Before SQL Server 2019 all we had was NCHAR and NVARCHAR fields. Some say they are UNICODE fields. THAT IS WRONG!. Again, it depends on the field's COLLATION and also SQLServer Version. Microsoft's "nchar and nvarchar (Transact-SQL)" documentation specifies perfectly:

Starting with SQL Server 2012 (11.x), when a Supplementary Character (SC) enabled collation is used, these data types store the full range of Unicode character data and use the UTF-16 character encoding. If a non-SC collation is specified, then these data types store only the subset of character data supported by the UCS-2 character encoding.

In other words, if we use SQL Server older that 2012, like SQL Server 2008 R2 for example, the ENCODING for those fields will use UCS-2 ENCODING which support a subset of UNICODE. But if we use SQL Server 2012 or newer, and define a COLLATION that has Supplementary Character enabled, than with our field will use the UTF-16 ENCODING, that fully supports UNICODE.

BUT WHAIT, THERE IS MORE! WE CAN USE UTF-8 NOW!!

CHAR/VARCHAR

Starting with SQL Server 2019, WE CAN USE CHAR/VARCHAR fields and still fully support UNICODE using UTF-8 ENCODING!!!

From Microsoft's "char and varchar (Transact-SQL)" documentation:

Starting with SQL Server 2019 (15.x), when a UTF-8 enabled collation is used, these data types store the full range of Unicode character data and use the UTF-8 character encoding. If a non-UTF-8 collation is specified, then these data types store only a subset of characters supported by the corresponding code page of that collation.

Again, in other words, if we use SQL Server older that 2019, like SQL Server 2008 R2 for example, we need to check the ENCODING using the method explained before. But if we use SQL Server 2019 or newer, and define a COLLATION like Latin1_General_100_CI_AS_SC_UTF8, then our field will use UTF-8 ENCODING which is by far the most used and efficient encoding that supports all the UNICODE characters.

Bonus Information:

Regarding the OP's observation on "I have seen that most of the European languages (German, Italian, English, ...) are fine in the same database in VARCHAR columns", I think it's nice to know why it is:

For the most common COLLATIONs, like the default ones as Latin1_General_CI_AI or SQL_Latin1_General_CP1_CI_AS the ENCODING will be Windows-1252 for varchar fields. If we take a look on it's documentation, we can see that it supports:

English, Irish, Italian, Norwegian, Portuguese, Spanish, Swedish. Plus also German, Finnish and French. And Dutch except the ? character

But as I said before, it's not about language, it's about what characters do you expect to support/store, as shown in the emoji example, or some sentence like "The electric resistance of a lithium battery is 0.5O" where we have again plain English, and a Greek letter/character "omega" (which is the symbol for resistance in ohms), which won't be correctly handled by Windows-1252 ENCODING.

Conclusion:

So, there it is! When use char/nchar and varchar/nvarchar depends on the characters that you want to support, and also the version of your SQL Server that will determines which COLLATIONs and hence the ENCODINGs you have available.

What is UNICODE, ENCODING, COLLATION and UTF-8, and how they are related
_{Note: all the explanations below are simplifications. Please, refer to the supplied documentation links to know all the details about those concepts.}

• UNICODE - Is a standard, a convention, that aims to regulate all the characters in a unified and organized table. In this table, every character has an unique number. This number is commonly called character's code point.
  UNICODE IS NOT AN ENCODING!

• ENCODING - Is a mapping between a character and a byte/bytes sequence. So a encoding is used to "transform" a character to bytes and also the other way around, from bytes to a character. Among the most popular ones are UTF-8, ISO-8859-1, Windows-1252 and ASCII. You can think of it as a "conversion table" (i really simplified here).

• COLLATION - That one is important. Even Microsoft's documentation doesn't let this clear as it should be. A Collation specifies how your data would be sorted, compared, AND STORED!. Yeah, I bet you was not expecting for that last one, right!? The collations on SQL Server determines too what would be the ENCODING used on that particular char/nchar/varchar/nvarchar field.

• ASCII ENCODING - Was one of the firsts encodings. It is both the character table (like an own tiny version of UNICODE) and its byte mappings. So it doesn't map a byte to UNICODE, but map a byte to its own character's table. Also, it always use only 7bits, and supported 128 different characters. It was enough to support all English letters upper and down cased, numbers, punctuation and some other limited number of characters. The problem with ASCII is that since it only used 7bits and almost every computer was 8bits at the time, there were another 128 possibilities of characters to be "explored", and everybody started to map this "available" bytes to its own table of characters, creating a lot of different ENCODINGs.

• UTF-8 ENCODING - This is another ENCODING, one of the most (if not the most) used ENCODING around. It uses variable byte width (one character can be from 1 to 6 bytes long, by specification) and fully supports all UNICODE characters.

• Windows-1252 ENCODING - Also one of the most used ENCODING, it's widely used on SQL Server. It's fixed-size, so every one character is always 1byte. It also supports a lot of accents, from various languages but doesn't support all existing, nor supports UNICODE. That's why your varchar field with a common collation like Latin1_General_CI_AS supports á,é,ñ characters, even that it isn't using a supportive UNICODE ENCODING.

In C char gets promoted to int in expressions. That pretty much explains every question, if you think about it.

Why not use title Right from the docs:

>>> "they're bill's friends from the UK".title()
"They'Re Bill'S Friends From The Uk"

If you really wanted PascalCase you can use this:

>>> ''.join(x for x in 'make IT pascal CaSe'.title() if not x.isspace())
'MakeItPascalCase'

You can write: [JsonProperty("property_name",DefaultValueHandling = DefaultValueHandling.Ignore)]

It also takes care of not serializing properties with default values (not only null). It can be useful for enums for example.

That's probably the C++ runtime library. Since it's a DLL it is not included in your program executable. Your friend can download those libraries from Microsoft.

Do not use public fields

Don't use public fields when you really want to wrap the internal behavior of a class. Take java.io.BufferedReader for example. It has the following field:

private boolean skipLF = false; // If the next character is a line feed, skip it

skipLF is read and written in all read methods. What if an external class running in a separate thread maliciously modified the state of skipLF in the middle of a read? BufferedReader will definitely go haywire.

Do use public fields

Take this Point class for example:

class Point {
    private double x;
    private double y;

    public Point(double x, double y) {
        this.x = x;
        this.y = y;
    }

    public double getX() {
        return this.x;
    }

    public double getY() {
        return this.y;
    }

    public void setX(double x) {
        this.x = x;
    }

    public void setY(double y) {
        this.y = y;
    }
}

This would make calculating the distance between two points very painful to write.

Point a = new Point(5.0, 4.0);
Point b = new Point(4.0, 9.0);
double distance = Math.sqrt(Math.pow(b.getX() - a.getX(), 2) + Math.pow(b.getY() - a.getY(), 2));

The class does not have any behavior other than plain getters and setters. It is acceptable to use public fields when the class represents just a data structure, and does not have, and never will have behavior (thin getters and setters is not considered behavior here). It can be written better this way:

class Point {
    public double x;
    public double y;

    public Point(double x, double y) {
        this.x = x;
        this.y = y;
    }
}

Point a = new Point(5.0, 4.0);
Point b = new Point(4.0, 9.0);
double distance = Math.sqrt(Math.pow(b.x - a.x, 2) + Math.pow(b.y - a.y, 2));

Clean!

But remember: Not only your class must be absent of behavior, but it should also have no reason to have behavior in the future as well.

(This is exactly what this answer describes. To quote "Code Conventions for the Java Programming Language: 10. Programming Practices":

One example of appropriate public instance variables is the case where the class is essentially a data structure, with no behavior. In other words, if you would have used a struct instead of a class (if Java supported struct), then it's appropriate to make the class's instance variables public.

So the official documentation also accepts this practice.)

Also, if you're extra sure that members of above Point class should be immutable, then you could add final keyword to enforce it:

public final double x;
public final double y;

I got this on Firefox (FF58). I fixed this with:

1. It is still experimental on Firefox (from v54): You have to set to true the variable dom.moduleScripts.enabled in about:config

Source: Import page on mozilla (See Browser compatibility)

2. Add type="module" to your script tag where you import the js file

<script type="module" src="appthatimports.js"></script>

3. Import files have to be prefixed (./, /, ../ or http:// before)

import * from "./mylib.js"

Not my code, but I think it's pretty nicely written. It allows to check by the key as well as by the Object element itself and handles both the On Error method and iterating through all Collection elements.

Flexible or liquid layouts do restict design a little though, for example if you use background images that have to match the body background image.

I would rather make different css layouts for the site and have them apply depending on the user's resolution, or if that's not possible (have not digged into that yet), make it a choosable option.

If you want to update it later, once "this" no longer references it, I had some luck with assigning a variable to point to the main form.

  static Form f0;
  public OrdUpdate()
  {
   InitializeComponent();
   f0=this;
  }
  // then later you can say
  f0.Text="New text";

You don't need (shouldn't use) a function as far as I can tell. The stored procedure will return tabular data from any SELECT statements you include that return tabular data.

A stored proc does not use RETURN statements.

 CREATE PROCEDURE name

Do attributes migrated from parent to child help identify¹ the child?

• If yes: the identification-dependence exists, the relationship is identifying and the child entity is "weak".
• If not: the identification-dependence doesn't exists, the relationship is non-identifying and the child entity "strong".

Note that identification-dependence implies existence-dependence, but not the other way around. Every non-NULL FK means a child cannot exist without parent, but that alone doesn't make the relationship identifying.

For more on this (and some examples), take a look at the "Identifying Relationships" section of the ERwin Methods Guide.

P.S. I realize I'm (extremely) late to the party, but I feel other answers are either not entirely accurate (defining it in terms of existence-dependence instead of identification-dependence), or somewhat meandering. Hopefully this answer provides more clarity...

¹ The child's FK is a part of child's PRIMARY KEY or (non-NULL) UNIQUE constraint.

This is working for me, Writing(creating as well) and/or appending content in the same mode.

If using GitHub on Windows:

1. Make changes locally.
2. Open GitHub, switch to local repositories, double click repository.
3. Switch the branch(near top of window) to the branch that you created the pull request from(i.e. the branch on your fork side of the compare)
4. Should see option to enter commit comment on right and commit changes to your local repo.
5. Click sync on top, which among other things, pushes your commit from local to your remote fork on GitHub.
6. The pull request will be updated automatically with the additional commits. This is because the pulled request represents a diff with your fork's branch. If you go to the pull request page(the one where you and others can comment on your pull request) then the Commits tab should have your additional commit(s).

This is why, before you start making changes of your own, that you should create a branch for each set of changes you plan to put into a pull request. That way, once you make the pull request, you can then make another branch and continue work on some other task/feature/bugfix without affecting the previous pull request.

This is one of the tricky parts of Javascript, but also one of its core features. A variable declared with var "begins its life" right where you declare it. If you leave out the var, it's like you're talking about a variable that you have used before.

var foo = 'first time use';
foo = 'second time use';

With regards to scope, it is not true that variables automatically become global. Rather, Javascript will traverse up the scope chain to see if you have used the variable before. If it finds an instance of a variable of the same name used before, it'll use that and whatever scope it was declared in. If it doesn't encounter the variable anywhere it'll eventually hit the global object (window in a browser) and will attach the variable to it.

var foo = "I'm global";
var bar = "So am I";

function () {
    var foo = "I'm local, the previous 'foo' didn't notice a thing";
    var baz = "I'm local, too";

    function () {
        var foo = "I'm even more local, all three 'foos' have different values";
        baz = "I just changed 'baz' one scope higher, but it's still not global";
        bar = "I just changed the global 'bar' variable";
        xyz = "I just created a new global variable";
    }
}

This behavior is really powerful when used with nested functions and callbacks. Learning about what functions are and how scope works is the most important thing in Javascript.

The usual error is one tries to put Content-Type: {multipart/form-data} into the header of the post request. That will fail, it is best to let Postman do it for you. For example:

Global variables are as bad as you make them, no less.

If you are creating a fully encapsulated program, you can use globals. It's a "sin" to use globals, but programming sins are laregly philosophical.

If you check out L.in.oleum, you will see a language whose variables are solely global. It's unscalable because libraries all have no choice but to use globals.

That said, if you have choices, and can ignore programmer philosophy, globals aren't all that bad.

Neither are Gotos, if you use them right.

The big "bad" problem is that, if you use them wrong, people scream, the mars lander crashes, and the world blows up....or something like that.

I followed the instructions above by Gene in Android Studio 1.5.1 but it added this to my build.gradle file:

compile 'platforms:android:android-support-v4:23.1.1'

so I changed it to:

compile 'com.android.support:support-v4:23.1.1'

And it started working.

What I usually do for small collections is to create kind of parser/converter method like this

def convertSetToList(setName):
return list(setName)

Then I can use the new list and access by index number

userFields = convertSetToList(user)
name = request.json[userFields[0]]

As a list you will have all the other methods that you may need to work with

You can pass in the element to the controller, just like the scope:

function someControllerFunc($scope, $element){

}

.dmp files are dumps of oracle databases created with the "exp" command. You can import them using the "imp" command.

If you have an oracle client intalled on your machine, you can executed the command

imp help=y

to find out how it works. What will definitely help is knowing from wich schema the data was exported and what the oracle version was.

Sometimes the .gz extension is wrongfully appended to the filename.

• Run file foo.csv.gz to know the actual file type.
• Rename the file to foo.csv or whatever the actual file type is.

Swift 3: for me it worked when you put it in the cellForRowAtIndexPath: method

let view = UIView()
view.backgroundColor = UIColor.red
cell.selectedBackgroundView = view

class FooObservableCollection : ObservableCollection<Foo>
{
    protected override void InsertItem(int index, Foo item)
    {
        base.Add(index, Foo);

        if (this.CollectionChanged != null)
            this.CollectionChanged(this, new NotifyCollectionChangedEventArgs (NotifyCollectionChangedAction.Add, item, index);
    }
}

var collection = new FooObservableCollection();
collection.CollectionChanged += CollectionChanged;

collection.Add(new Foo());

void CollectionChanged (object sender, NotifyCollectionChangedEventArgs e)
{
    Foo newItem = e.NewItems.OfType<Foo>().First();
}

You can do it with FormBuilder. Add this to the array in your FormBuilder:

'attr'=> array('class'=>'span2')

Nobody said how to install apt-cyg

in cygwin

lynx -source rawgit.com/transcode-open/apt-cyg/master/apt-cyg > apt-cyg
install apt-cyg /bin

now you can

apt-cyg install curl

For more, see the official github repository of apt-cyg.

I'm not sure about g++, but if you're using GNU Make then "make -j N" (where N is the number of threads make can create) will allow make to run multple g++ jobs at the same time (so long as the files do not depend on each other).

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

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

Then your @POST method would look like the following:

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

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

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

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

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

HTML <FORM>

The parameters would be annotated using @FormParam:

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

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

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

param1=hello&param2=world

The content is URL encoded in this case.

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

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

HTTP Headers

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

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

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

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

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

HTTP Query Parameters

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

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

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

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

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

HTTP Path Parameters

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

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

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

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

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

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

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

you haven't loaded driver into memory. use this following in init()

Class.forName("com.mysql.jdbc.Driver");

Also, you missed a colon (:) in url, use this

String mySqlUrl = "jdbc:mysql://localhost:3306/mysql";

Just in case anybody else lands here from Google, I was bitten by this error message when using XDocument.Load(Stream) method.

XDocument xDoc = XDocument.Load(xmlStream);  

Make sure the stream position is set to 0 (zero) before you try and load the Stream, its an easy mistake I always overlook!

if (xmlStream.Position > 0)
{
    xmlStream.Position = 0;
}
XDocument xDoc = XDocument.Load(xmlStream); 

Actually, this is the proper way to get what you want, unless you can use MS SQL 2014 (which finally enables custom format strings for date times).

To get yyyymm instead of yyyym, you can use this little trick:

select 
 right('0000' + cast(datepart(year, getdate()) as varchar(4)), 4)
 + right('00' + cast(datepart(month, getdate()) as varchar(2)), 2)

It's faster and more reliable than gettings parts of convert(..., 112).

Also you can convert any number in any base to hex. Use this one line code here it's easy and simple to use:

hex(int(n,x)).replace("0x","")

You have a string n that is your number and x the base of that number. First, change it to integer and then to hex but hex has 0x at the first of it so with replace we remove it.

Try this to get value from select element by Element Name

$("select[name=elementnamehere]").val();

You are using " instead of ' It is mixing up php syntax with javascript. PHP is going to print javascript with echo function, but it is taking the js codes as wrong php syntax. so try this,

<html>
<body>
<?php

echo "<script type='text/javascript'>";
echo "document.write('Hello World!')";
echo "</script>";

?>
</body>
</html>

Below is an example of such a query:

SELECT [1].[Mobile Number], [1].[Mobile Series], [1].[Full Name], [1].[Full Address], [1].[Active Date], [1].[Company Name]
FROM 1

A Dependency Free Multiclass Confusion Matrix

# A Simple Confusion Matrix Implementation
def confusionmatrix(actual, predicted, normalize = False):
    """
    Generate a confusion matrix for multiple classification
    @params:
        actual      - a list of integers or strings for known classes
        predicted   - a list of integers or strings for predicted classes
        normalize   - optional boolean for matrix normalization
    @return:
        matrix      - a 2-dimensional list of pairwise counts
    """
    unique = sorted(set(actual))
    matrix = [[0 for _ in unique] for _ in unique]
    imap   = {key: i for i, key in enumerate(unique)}
    # Generate Confusion Matrix
    for p, a in zip(predicted, actual):
        matrix[imap[p]][imap[a]] += 1
    # Matrix Normalization
    if normalize:
        sigma = sum([sum(matrix[imap[i]]) for i in unique])
        matrix = [row for row in map(lambda i: list(map(lambda j: j / sigma, i)), matrix)]
    return matrix

The approach here is to pair up the unique classes found in the actual vector into a 2-dimensional list. From there, we simply iterate through the zipped actual and predicted vectors and populate the counts using the indices to access the matrix positions.

Usage

cm = confusionmatrix(
    [1, 1, 2, 0, 1, 1, 2, 0, 0, 1], # actual
    [0, 1, 1, 0, 2, 1, 2, 2, 0, 2]  # predicted
)

# And The Output
print(cm)
[[2, 1, 0], [0, 2, 1], [1, 2, 1]]

Note: the actual classes are along the columns and the predicted classes are along the rows.

# Actual
# 0  1  2
  #  #  #   
[[2, 1, 0], # 0
 [0, 2, 1], # 1  Predicted
 [1, 2, 1]] # 2

Class Names Can be Strings or Integers

cm = confusionmatrix(
    ["B", "B", "C", "A", "B", "B", "C", "A", "A", "B"], # actual
    ["A", "B", "B", "A", "C", "B", "C", "C", "A", "C"]  # predicted
)

# And The Output
print(cm)
[[2, 1, 0], [0, 2, 1], [1, 2, 1]]

You Can Also Return The Matrix With Proportions (Normalization)

cm = confusionmatrix(
    ["B", "B", "C", "A", "B", "B", "C", "A", "A", "B"], # actual
    ["A", "B", "B", "A", "C", "B", "C", "C", "A", "C"], # predicted
    normalize = True
)

# And The Output
print(cm)
[[0.2, 0.1, 0.0], [0.0, 0.2, 0.1], [0.1, 0.2, 0.1]]

A More Robust Solution

Since writing this post, I've updated my library implementation to be a class that uses a confusion matrix representation internally to compute statistics, in addition to pretty printing the confusion matrix itself. See this Gist.

Example Usage

# Actual & Predicted Classes
actual      = ["A", "B", "C", "C", "B", "C", "C", "B", "A", "A", "B", "A", "B", "C", "A", "B", "C"]
predicted   = ["A", "B", "B", "C", "A", "C", "A", "B", "C", "A", "B", "B", "B", "C", "A", "A", "C"]

# Initialize Performance Class
performance = Performance(actual, predicted)

# Print Confusion Matrix
performance.tabulate()

With the output:

===================================
        A?      B?      C?

A?      3       2       1

B?      1       4       1

C?      1       0       4

Note: class? = Predicted, class? = Actual
===================================

And for the normalized matrix:

# Print Normalized Confusion Matrix
performance.tabulate(normalized = True)

With the normalized output:

===================================
        A?      B?      C?

A?      17.65%  11.76%  5.88%

B?      5.88%   23.53%  5.88%

C?      5.88%   0.00%   23.53%

Note: class? = Predicted, class? = Actual
===================================

You can comment section of a script using a conditional.

For example, the following script:

DEBUG=false
if ${DEBUG}; then
echo 1
echo 2
echo 3
echo 4
echo 5
fi
echo 6
echo 7

would output:

6
7

In order to uncomment the section of the code, you simply need to comment the variable:

#DEBUG=false

(Doing so would print the numbers 1 through 7.)

jQuery(document).ready(function(){
    jQuery('#datetimepicker').datepicker();
})

I don't know your file-structure. I never include local files like this as I use relative URLs from the start rather than having to change everytime I'm ready to use the code, but it's likely one of the files isn't being loaded in. I've included the standard datepicker below using Google CDN's jQuery UI. Does your console log any resources not found?

I think your jQuery is loaded OK, because it's not telling you jQuery is not defined so it's one of your files.

BTW, PHP gets the home URL:

$home="http://" . $_SERVER['HTTP_HOST'].'/';

Demo code datepicker, jQuery UI:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<link rel="stylesheet" href="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/themes/smoothness/jquery-ui.css" />
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js"></script>

<script type="text/javascript">
    jQuery(document).ready(function(){
        jQuery('#datetimepicker').datepicker();
    })
</script>

<input id="datetimepicker" type="text">

I would use an asynchronous access using a completion block.

This example saves the Google logo to the document directory of the device. (iOS 5+, OSX 10.7+)

NSString *documentDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];
NSString *filePath = [documentDir stringByAppendingPathComponent:@"GoogleLogo.png"];

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"https://www.google.com/images/srpr/logo11w.png"]];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue currentQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
    if (error) {
        NSLog(@"Download Error:%@",error.description);
    }
    if (data) {
        [data writeToFile:filePath atomically:YES];
        NSLog(@"File is saved to %@",filePath);
    }
}];

You can create the single value array key-value as

$new_row = array($row["datasource_id"]=>$row["title"]);

inside while loop, and then use array_merge function in loop to combine the each new $new_row array.

As stated in MSDN (eg. https://msdn.microsoft.com/en-us/library/system.diagnostics.eventlog(v=vs.110).aspx ), checking an non existing source and creating a source requires admin privilege.

It is however possible to use the source "Application" without. In my test under Windows 2012 Server r2, I however get the following log entry using "Application" source:

The description for Event ID xxxx from source Application cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: {my event entry message} the message resource is present but the message is not found in the string/message table

I defined the following method to create the source:

    private string CreateEventSource(string currentAppName)
    {
        string eventSource = currentAppName;
        bool sourceExists;
        try
        {
            // searching the source throws a security exception ONLY if not exists!
            sourceExists = EventLog.SourceExists(eventSource);
            if (!sourceExists)
            {   // no exception until yet means the user as admin privilege
                EventLog.CreateEventSource(eventSource, "Application");
            }
        }
        catch (SecurityException)
        {
            eventSource = "Application";
        }

        return eventSource;
    }

I am calling it with currentAppName = AppDomain.CurrentDomain.FriendlyName

It might be possible to use the EventLogPermission class instead of this try/catch but not sure we can avoid the catch.

It is also possible to create the source externally, e.g in elevated Powershell:

New-EventLog -LogName Application -Source MyApp

Then, using 'MyApp' in the method above will NOT generate exception and the EventLog can be created with that source.

Based on my highly scientific and accurate experiment, it tops out on my machine well before 1,000,000,000 characters. (I'm still running the code below to get a better pinpoint).

UPDATE: After a few hours, I've given up. Final results: Can go a lot bigger than 100,000,000 characters, instantly given System.OutOfMemoryException at 1,000,000,000 characters.

The character in question &#65279 is the Unicode Character 'ZERO WIDTH NO-BREAK SPACE' (U+FEFF). It may be that you copied it into your code via a copy/paste without realizing it. The fact that it's not visible makes it hard to tell if you're using an editor that displays actual unicode characters.

One option is to open the file in a very basic text editor that doesn't understand unicode, or one that understands it but has the ability to display any non-ascii characters using their actual codes.

Once you locate it, you can delete the small block of text around it and retype that text manually.

The only way to do this is via various CSS hacks, which will make your page much more likely to fail on the next browser updates. If anything, it will be LESS safe than using a js-browser sniffer.

1. Open "Settings"

3. Click on "Ignored Files" under "Maven"
4. Uncheck the pom.xml files contains the missing dependencies
5. Click "OK"

As I was searching for Scala version, all I could find was McDowell's JNA code above. I include my Scala port here, as there currently isn't anywhere more appropriate.

import com.sun.jna.platform.win32._
object jna {
    def getHome: java.io.File = {
        if (!com.sun.jna.Platform.isWindows()) {
            new java.io.File(System.getProperty("user.home"))
        }
        else {
            val pszPath: Array[Char] = new Array[Char](WinDef.MAX_PATH)
            new java.io.File(Shell32.INSTANCE.SHGetSpecialFolderPath(null, pszPath, ShlObj.CSIDL_MYDOCUMENTS, false) match {
                case true => new String(pszPath.takeWhile(c => c != '\0'))
                case _    => System.getProperty("user.home")
            })
        }
    }
}

As with the Java version, you will need to add Java Native Access, including both jar files, to your referenced libraries.

It's nice to see that JNA now makes this much easier than when the original code was posted.

1. Make sure you logged on as an administrator or you have the same access as an administrator.

Here's a brief tutorial on how __doPostBack() works.

To be honest, I don't use it much; at least directly. Many server controls, (e.g., Button, LinkButton, ImageButton, parts of the GridView, etc.) use __doPostBack as their post back mechanism.

This generates a consistent hash based on any number of params passed in:

/**
 * Generates a hash from params passed in
 * @returns {string} hash based on params
 */
function fastHashParams() {
    var args = Array.prototype.slice.call(arguments).join('|');
    var hash = 0;
    if (args.length == 0) {
        return hash;
    }
    for (var i = 0; i < args.length; i++) {
        var char = args.charCodeAt(i);
        hash = ((hash << 5) - hash) + char;
        hash = hash & hash; // Convert to 32bit integer
    }
    return String(hash);
}

fastHashParams('hello world') outputs "990433808"

fastHashParams('this',1,'has','lots','of','params',true) outputs "1465480334"

Try this instead:

(SolidColorBrush)(new BrushConverter().ConvertFrom("#ffaacc"));

In my experience, it's just a matter of iteration. Put your data and code wherever you think they go. Chances are, you'll be wrong anyway. But once you get a better idea of exactly how things are going to shape up, you're in a much better position to make these kinds of guesses.

As far as extension sources, we have a Code directory under trunk that contains a directory for python and a directory for various other languages. Personally, I'm more inclined to try putting any extension code into its own repository next time around.

With that said, I go back to my initial point: don't make too big a deal out of it. Put it somewhere that seems to work for you. If you find something that doesn't work, it can (and should) be changed.

This is a late answer. However, I thought of putting the struggle I had to bear to get a shell script to be executed from a Spring-Boot application for future developers.

1. I was working in Spring-Boot and I was not able to find the file to be executed from my Java application and it was throwing FileNotFoundFoundException. I had to keep the file in the resources directory and had to set the file to be scanned in pom.xml while the application was being started like the following.

   <resources>
       <resource>
           <directory>src/main/resources</directory>
           <filtering>true</filtering>
           <includes>
               <include>**/*.xml</include>
               <include>**/*.properties</include>
               <include>**/*.sh</include>
           </includes>
       </resource>
   </resources>
   

2. After that I was having trouble executing the file and it was returning error code = 13, Permission Denied. Then I had to make the file executable by running this command - chmod u+x myShellScript.sh

Finally, I could execute the file using the following code snippet.

public void runScript() {
    ProcessBuilder pb = new ProcessBuilder("src/main/resources/myFile.sh");
    try {
        Process p;
        p = pb.start();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

Hope that solves someone's problem.

You can use vertical-align to move items vertically.

Example:

<div>This is an <span style="vertical-align: -20px;">example</span></div>

This will move the span containing the word 'example' downwards 20 pixels compared to the rest of the text.

The intended use for this property is to align elements of different height (e.g. images with different sizes) along a set line. vertical-align: top will for instance align all images on a line with the top of each image aligning with each other. vertical-align: middle will align all images so that the middle of the images align with each other, regardless of the height of each image.

You can see visual examples in this CodePen by Chris Coyier.

Hope that helps!

I found the answer after posting the enhancement to the question. Sorry!

MS Excel helped!

simply add the Hex prefix to the hex colour value to add an alpha that has the equivalent opacity as the % value.

(in rbga the percentage opacity is expressed as a decimal as mentioned above)

The opacity property of the outer DIV cannot be undone by the inner DIV. If you want to achieve transparency, use rgba or hsla:

Outer div:

background-color: rgba(255, 255, 255, 0.9); /* Color white with alpha 0.9*/

Inner div:

background-color: #FFF; /* Background white, to override the background propery*/

EDIT
Because you've added filter:alpha(opacity=90) to your question, I assume that you also want a working solution for (older versions of) IE. This should work (-ms- prefix for the newest versions of IE):

/*Padded for readability, you can write the following at one line:*/
filter: progid:DXImageTransform.Microsoft.Gradient(
    GradientType=1,
    startColorStr="#E6FFFFFF",
    endColorStr="#E6FFFFFF");

/*Similarly: */
filter: progid:DXImageTransform.Microsoft.Gradient(
    GradientType=1,
    startColorStr="#E6FFFFFF",
    endColorStr="#E6FFFFFF");

I've used the Gradient filter, starting with the same start- and end-color, so that the background doesn't show a gradient, but a flat colour. The colour format is in the ARGB hex format. I've written a JavaScript snippet to convert relative opacity values to absolute alpha-hex values:

var opacity = .9;
var A_ofARGB = Math.round(opacity * 255).toString(16);
if(A_ofARGB.length == 1) A_ofARGB = "0"+a_ofARGB;
else if(!A_ofARGB.length) A_ofARGB = "00";
alert(A_ofARGB);

There are errors in your meta tag.

Yours:

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src: 'self' 'unsafe-inline' 'unsafe-eval'>

Corrected:

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'"/>

Note the colon after "script-src", and the end double-quote of the meta tag.

Use the % instead of the / when you divide. This will return the remainder for you. So in your case

26 % 7 = 5

$.getJSon expects a callback functions either you pass it to the callback function or in callback function assign it to global variale.

var globalJsonVar;

    $.getJSON("http://127.0.0.1:8080/horizon-update", function(json){
               //do some thing with json  or assign global variable to incoming json. 
                globalJsonVar=json;
          });

IMO best is to call the callback function. which is nicer to eyes, readability aspects.

$.getJSON("http://127.0.0.1:8080/horizon-update", callbackFuncWithData);

function callbackFuncWithData(data)
{
 // do some thing with data 
}

For a Windows console app, you want to use SetConsoleCtrlHandler to handle CTRL+C and CTRL+BREAK.

See here for an example.

try:
      doSomething()
except Exception: 
    pass
else:
      stuffDoneIf()
      TryClauseSucceeds()

FYI the else clause can go after all exceptions and will only be run if the code in the try doesn't cause an exception.

Using an Array:

String[] fruits = new String[3]; // make a 3 element array
fruits[0]="apple";
fruits[1]="banana";

Using a List

ArrayList<String> fruits = new ArrayList<String>();
fruits.add("apple");
fruits.add("banana");
fruits.add("orange");
System.out.println(fruits.get(1));

Check your updated information in php.ini file

Using Windows explorer:

C/xampp/php/php.ini

Using XAMPP Control Panel

1. Click the Config button for 'Apache' (Stop | Admin | Config | Logs)
2. Select PHP (php.ini)

Can i create my own phpinfo()? Yes you can

1. Create a phpinfo.php in your root directly or anywhere you want
2. Place this <?php phpinfo(); ?>
3. Save the file.
4. Open the file and you should see all the details.

How to set display_errors to Off in my own file without using php.ini

You can do this using ini_set() function. Read more about ini_set() here (https://www.php.net/manual/en/function.ini-set.php)

1. Go to your header.php or index.php
2. add this code ini_set('display_errors', FALSE);

To check the output without accessing php.ini file

$displayErrors = (ini_get('display_errors') == 1) ? 'On' : 'Off';
$PHPCore = array(
    'Display error' => $displayErrors
    // add other details for more output
);
foreach ($PHPCore as $key => $value) {
    echo "$key: $value";
}

Database directory read-write permission also a problem i found. Just make sure your application is able to rw files on db location. Try chmod 777 for testing.

Error in file(file, "rt") :

I just faced the same error and resolved by removing spacing in address using paste0 instead of paste

filepath=paste0(directory,"/",filename[1],sep="")

In my case I have declared a Bool like this:

var isActivityOpen: Bool 

i.e. I declared it without unwrapping so, This is how I solved the (no initializer) error :

var isActivityOpen: Bool!

Based on http://code.msdn.microsoft.com/101-LINQ-Samples-3fb9811b,

EqualAll is the approach that best meets your needs.

public void Linq96() 
{ 
    var wordsA = new string[] { "cherry", "apple", "blueberry" }; 
    var wordsB = new string[] { "cherry", "apple", "blueberry" }; 

    bool match = wordsA.SequenceEqual(wordsB); 

    Console.WriteLine("The sequences match: {0}", match); 
} 

I also like to define my own functions that take and return arguments in degrees rather than radians. I am sure there some capitalization purest who don't like my names, but I just use a capital first letter for my custom functions. The definitions and testing code are below.

#Definitions for trig functions using degrees.
def Cos(a):
    return cos(radians(a))
def Sin(a):
    return sin(radians(a))
def Tan(a):
    return tan(radians(a))
def ArcTan(a):
    return degrees(arctan(a))
def ArcSin(a):
    return degrees(arcsin(a))
def ArcCos(a):
    return degrees(arccos(a))

#Testing Code
print(Cos(90))
print(Sin(90))
print(Tan(45))
print(ArcTan(1))
print(ArcSin(1))
print(ArcCos(0))

Note that I have imported math (or numpy) into the namespace with

from math import *

Also note, that my functions are in the namespace in which they were defined. For instance,

math.Cos(45)

does not exist.

That's how I achieved it, which is not visible (HORRIBLE SOUND....)

<!-- horrible is your mp3 file name any other supported format.-->
<audio controls autoplay hidden="" src="horrible.mp3" type ="audio/mp3"">your browser does not support Html5</audio>

I found solution. It works fine when I throw away next line from form:

enctype="multipart/form-data"

And now it pass all parameters at request ok:

 <form action="/registration" method="post">
   <%-- error messages --%>
   <div class="form-group">
    <c:forEach items="${registrationErrors}" var="error">
    <p class="error">${error}</p>
     </c:forEach>
   </div>

Just In case: while using the command line to generate the SHA1 fingerprint, be careful while specifying the folder path. If your User Name or android folder path has a space, you should add two double quotes as below:

keytool -list -v -keystore "C:\Users\User Name\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

#include <stdio.h>
#include <string.h>

int main() {
    char src[] = "SexDrugsRocknroll";
    char dest[5] = { 0 }; // 4 chars + terminator */
    int len = strlen(src);
    int i = 0;

    while (i*4 < len) {
        strncpy(dest, src+(i*4), 4);
        i++;

        printf("loop %d : %s\n", i, dest);
    }
}

The right way of using inArray(x, arr) is not using it at all, and using instead arr.indexOf(x).

The official standard name is also more clear on the fact that the returned value is an index thus if the element passed is the first one you will get back a 0 (that is falsy in Javascript).

(Note that arr.indexOf(x) is not supported in Internet Explorer until IE9, so if you need to support IE8 and earlier, this will not work, and the jQuery function is a better alternative.)

For Temporal Tables it is a bit more complicated due to the fact there may be some foreign keys and also exception:

Drop table operation failed on table XXX because it is not a supported operation on system-versioned temporal tables

What you can use is:

-- Disable constraints (foreign keys)
EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
GO

-- Disable system versioning (temporial tables)
EXEC sp_MSForEachTable '
 IF OBJECTPROPERTY(object_id(''?''), ''TableTemporalType'') = 2
  ALTER TABLE ? SET (SYSTEM_VERSIONING = OFF)
'
GO

-- Removing tables
EXEC sp_MSForEachTable 'DROP TABLE ?'
GO

Here's an approach using tbody elements that could be the way to do it. You can't set the border on a tbody (same as you can't on a tr) but you can set the background colour. If the effect you're wanting to acheive can be obtained with a background colour on the groups of rows instead of a border this will work.

<table cellspacing="0">  
    <tbody>
        <tr>    
            <td>no border</td>    
            <td>no border here either</td>  
        </tr>  
    <tbody bgcolor="gray">
        <tr>    
            <td>one</td>    
            <td>two</td>  
        </tr>  
        <tr>    
            <td>three</td>    
            <td>four</td>  
        </tr>  
    <tbody>
        <tr>    
             <td colspan="2">once again no borders</td>  
        </tr>  
    <tbody bgcolor="gray">
        <tr>    
             <td colspan="2">hello</td>  
        </tr>
    <tbody>
    <tr>    
         <td colspan="2">world</td>  
    </tr>
</table>

I had to import also the language:

import moment from 'moment'
import 'moment/locale/es'  // without this line it didn't work
moment.locale('es')

Then use moment like you normally would

alert(moment(date).fromNow())

If you want to set something on a timer, you can use JavaScript's setTimeout or setInterval methods:

setTimeout ( expression, timeout );
setInterval ( expression, interval );

Where expression is a function and timeout and interval are integers in milliseconds. setTimeout runs the timer once and runs the expression once whereas setInterval will run the expression every time the interval passes.

So in your case it would work something like this:

setInterval(function() {
    //call $.ajax here
}, 5000); //5 seconds

As far as the Ajax goes, see jQuery's ajax() method. If you run an interval, there is nothing stopping you from calling the same ajax() from other places in your code.

If what you want is for an interval to run every 30 seconds until a user initiates a form submission...and then create a new interval after that, that is also possible:

setInterval() returns an integer which is the ID of the interval.

var id = setInterval(function() {
    //call $.ajax here
}, 30000); // 30 seconds

If you store that ID in a variable, you can then call clearInterval(id) which will stop the progression.

Then you can reinstantiate the setInterval() call after you've completed your ajax form submission.

Try sudo npm uninstall cordova -g to uninstall it globally and then just npm install cordova without the -g flag after cding to the local app directory

You can try as follows:

//------ js/functions.js ------
export function square(x) {
    return x * x;
}
export function diag(x, y) {
    return sqrt(square(x) + square(y));
}

//------ js/main.js ------
import { square, diag } from './functions.js';
console.log(square(11)); // 121
console.log(diag(4, 3)); // 5

You can also import completely:

//------ js/main.js ------
import * as lib from './functions.js';
console.log(lib.square(11)); // 121
console.log(lib.diag(4, 3)); // 5

Normally we use ./fileName.js for importing own js file/module and fileName.js is used for importing package/library module

When you will include the main.js file to your webpage you must set the type="module" attribute as follows:

<script type="module" src="js/main.js"></script>

For more details please check ES6 modules

This might be due to the fact that you are trying to add a ListBoxItem with a same name to the page.

If you want to refresh the content of the listbox with the newly retrieved values you will have to first manually remove the content of the listbox other wise your loop will try to create lb_1 again and add it to the same list.

Easiest way to get it by using date pattern - h:mm a, where

• h - Hour in am/pm (1-12)
• m - Minute in hour
• a - Am/pm marker

In my experience this error is pretty common, for some reason jersey sometimes has problems parsing custom java types. Usually all you have to do is make sure that you respect the following 3 conditions:

1. you have jersey-media-json-jackson in you pom.xml if using maven or added to your build path;
2. you have an empty constructor in the data type you are trying to de-/serialize;
3. you have the relevant annotation at the class and field level for your custom data type (xmlelement and/or jsonproperty);

However, I have ran into cases where this just was not enough. Then you can always wrap you custom data type in a GenericEntity and pass it as such to your ResponseBuilder:

GenericEntity<CustomDataType> entity = new GenericEntity<CustomDataType>(myObj) {};
return Response.status(httpCode).entity(entity).build();

This way you are trying to help jersey to find the proper/relevant serialization provider for you object. Well, sometimes this also is not enough. In my case I was trying to produce a text/plain from a custom data type. Theoretically jersey should have used the StringMessageProvider, but for some reason that I did not manage to discover it was giving me this error:

org.glassfish.jersey.message.internal.MessageBodyProviderNotFoundException: MessageBodyWriter not found for media type=text/plain

So what solved the problem for me was to do my own serialization with jackson's writeValueAsString(). I'm not proud of it but at the end of the day I can deliver an acceptable solution.

Put this in your server directive:

location /issue {
   rewrite ^/issue(.*) http://$server_name/shop/issues/custom_issue_name$1 permanent;
 }

Or duplicate it:

location /issue1 {
   rewrite ^/.* http://$server_name/shop/issues/custom_issue_name1 permanent;
}
location /issue2 {
   rewrite ^.* http://$server_name/shop/issues/custom_issue_name2 permanent;
}
 ...

Ok I have managed to achieve an animation when the page loads using only css transitions (sort of!):

I have created 2 css style sheets: the first is how I want the html styled before the animation... and the second is how I want the page to look after the animation has been carried out.

I don't fully understand how I have accomplished this but it only works when the two css files (both in the head of my document) are separated by some javascript as follows.

I have tested this with Firefox, safari and opera. Sometimes the animation works, sometimes it skips straight to the second css file and sometimes the page appears to be loading but nothing is displayed (perhaps it is just me?)

Here is a link to my work-in-progress website: http://www.hankins-design.co.uk/beta2/test/index.html

Maybe I'm wrong but I thought browsers that do not support css transitions should not have any issues as they should skip straight to the second css file without delay or duration.

I am interested to know views on how search engine friendly this method is. With my black hat on I suppose I could fill a page with keywords and apply a 9999s delay on its opacity.

I would be interested to know how search engines deal with the transition-delay attribute and whether, using the method above, they would even see the links and information on the page.

More importantly I would really like to know why this is not consistent each time the page loads and how I can rectify this!

I hope this can generate some views and opinions if nothing else!

This is lighter weight than xrange (and the while loop) since it doesn't even need to create the int objects. It also works equally well in Python2 and Python3

from itertools import repeat
for i in repeat(None, 10):
    do_sth()

I suggest an improvement of the Adam's answer accepting HashMap as parameter

/**
 * Append parameters to given url
 * @param url
 * @param parameters
 * @return new String url with given parameters
 * @throws URISyntaxException
 */
public static String appendToUrl(String url, HashMap<String, String> parameters) throws URISyntaxException
{
    URI uri = new URI(url);
    String query = uri.getQuery();

    StringBuilder builder = new StringBuilder();

    if (query != null)
        builder.append(query);

    for (Map.Entry<String, String> entry: parameters.entrySet())
    {
        String keyValueParam = entry.getKey() + "=" + entry.getValue();
        if (!builder.toString().isEmpty())
            builder.append("&");

        builder.append(keyValueParam);
    }

    URI newUri = new URI(uri.getScheme(), uri.getAuthority(), uri.getPath(), builder.toString(), uri.getFragment());
    return newUri.toString();
}

Every time you rollback you get the last batch of migration. use the command

php artisan migrate:rollback --step=1

Html

<img id="imgElem"></img>

Js

string baseStr64="/9j/4AAQSkZJRgABAQE...";
imgElem.setAttribute('src', "data:image/jpg;base64," + baseStr64);

The corrected code is

import urllib.request
fhand = urllib.request.urlopen('http://data.pr4e.org/romeo.txt')
counts = dict()
for line in fhand: 
    words = line.decode().split() 
for word in words: 
    counts[word] = counts.get(word, 0) + 1 
print(counts) 

running the code above produces

{'Who': 1, 'is': 1, 'already': 1, 'sick': 1, 'and': 1, 'pale': 1, 'with': 1, 'grief': 1}

If that is really all the batch file is doing, remove the cmd /K and add PAUSE.

start /B /LOW /WAIT make package
PAUSE

Then, just point your shortcut to "My Batch File.bat"...no need to run it with CMD /K.

UPDATE

Ah, some new info...you're trying to do it from a pinned shortcut on the taskbar.

I found this, Adding Batch Files to Windows 7 Taskbar like the Vista/XP Quick Launch, with the relevant part below.

1. First, pin a shortcut for CMD.EXE to the taskbar by hitting the start button, then type "cmd" in the search box, right-click the result and chose "Pin to Taskbar".
2. Right-click the shortcut on the taskbar.
3. You will see a list that includes "Command Prompt" and "Unpin this program from the taskbar".
4. Right-click the icon for CMD.EXE and select Properties.
5. In the box for Target, go to the end of "%SystemRoot%\system32\cmd.exe" and type " /C " and the path and name of the batch file.

For your purposes, you can either:

1. Use /C and put a PAUSE at the end of your batch file.

   OR

2. Change the command line to use /K and remove the PAUSE from your batch file.

I guess what you're trying to do, is to keep the header fixed and to scroll the body content. You can scroll the content into 2 directions:

• horizontally: you won't be able to scroll the content horizontally unless you use a slider (a jQuery slider for example). I would recommend to avoid using a table in this case.
• vertically: you won't be able to achieve that with a tbody tag, because assigning display:block or display:inline-block will break the layout of the table.

Here's a solution using divs: JSFiddle

HTML:

<div class="wrap_header">
    <div class="column">
        Name
    </div>
    <div class="column">
        Phone
    </div>
    <div class="clearfix"></div>
</div>
<div class="wrap_body">
    <div class="sliding_wrapper">
        <div class="serie">
            <div class="cell">

            <div class="clearfix"></div>
        </div>
        <div class="serie">
            <div class="cell">

            <div class="clearfix"></div>
        </div>
    </div>
</div>

CSS:

.wrap_header{width:204px;}
.sliding_wrapper,
.wrap_body {width:221px;}
.sliding_wrapper {overflow-y:scroll; overflow-x:none;}
.sliding_wrapper,

.clearfix:after {
    visibility:hidden;
    display:block;
    font-size:0;
    content:" ";
    clear:both;
    height:0;
}
.clearfix {display:inline-table;}

/**

 */
    /* Hides from IE-mac \*/
    * html .clearfix {height:1%;}
    .clearfix {display:block;}
    /* End hide from IE-mac */

Explanation:

You have a sliding wrapper which will contain all the data.

Note the following:

.wrap_header{width:204px;}
.sliding_wrapper,
.wrap_body {width:221px;}

There's a difference of 17px because we need to take into consideration the width of the scrollbar.

Hash maps are built-in in Python, they're called dictionaries:

streetno = {}                        #create a dictionary called streetno
streetno["1"] = "Sachin Tendulkar"   #assign value to key "1"

Usage:

"1" in streetno                      #check if key "1" is in streetno
streetno["1"]                        #get the value from key "1"

See the documentation for more information, e.g. built-in methods and so on. They're great, and very common in Python programs (unsurprisingly).

If you're anything like me, you won't want to go through changing each index every time you want to change the column you're sorting by.

function sortByColumn(a, colIndex){

    a.sort(sortFunction);

    function sortFunction(a, b) {
        if (a[colIndex] === b[colIndex]) {
            return 0;
        }
        else {
            return (a[colIndex] < b[colIndex]) ? -1 : 1;
        }
    }

    return a;
}

var sorted_a = sortByColumn(a, 2);

push is a native javascript method. You could use it like this:

var array = [1, 2, 3];
array.push(4); // array now is [1, 2, 3, 4]
array.push(5, 6, 7); // array now is [1, 2, 3, 4, 5, 6, 7]

Try Ehcache? It allows you to plug in your own caching expiry algorithms so you could control your peek functionality.

You can serialize to disk, database, across a cluster etc...

self is the self-reference in a Class. Your code is not in a class, you only have functions defined. You have to wrap your methods in a class, like below. To use the method main(), you first have to instantiate an object of your class and call the function on the object.

Further, your function setavalue should be in __init___, the method called when instantiating an object. The next step you probably should look at is supplying the name as an argument to init, so you can create arbitrarily named objects of the Name class ;)

class Name:
    def __init__(self):
        self.myname = "harry"

    def printaname(self):
        print "Name", self.myname     

    def main(self):
        self.printaname()

if __name__ == "__main__":
    objName = Name()
    objName.main()

It's not like you absolutly can't get around privateness of members in any language (pointer arithmetics in C++, Reflections in .NET/Java).

The point is that you get an error if you try to call the private method by accident. But if you want to shoot yourself in the foot, go ahead and do it.

Edit: You don't try to secure your stuff by OO-encapsulation, do you?

You can use this plugin, but for printing purpose i have added some code like <button onclick="window.print();">Print</button> and for saving image <button onclick="savePhoto();">Save Picture</button>

     function savePhoto() {
     var canvas = document.getElementById("canvas");
     var img    = canvas.toDataURL("image/png");
     window.location = img;}

checkout this plugin http://www.williammalone.com/articles/create-html5-canvas-javascript-drawing-app

All commands must be executed while connected to the right database in the right database cluster. Make sure of it.

The user needs access to the database, obviously:

GRANT CONNECT ON DATABASE my_db TO my_user;

And (at least) the USAGE privilege on the schema:

GRANT USAGE ON SCHEMA public TO my_user;

Or grant USAGE on all custom schemas:

DO
$$
BEGIN
   -- RAISE NOTICE '%', (  -- use instead of EXECUTE to see generated commands
   EXECUTE (
   SELECT string_agg(format('GRANT USAGE ON SCHEMA %I TO my_user', nspname), '; ')
   FROM   pg_namespace
   WHERE  nspname <> 'information_schema' -- exclude information schema and ...
   AND    nspname NOT LIKE 'pg\_%'        -- ... system schemas
   );
END
$$;

Then, all permissions for all tables (requires Postgres 9.0 or later).
And don't forget sequences (if any):

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO my_user;
GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public TO my_user;

For older versions you could use the "Grant Wizard" of pgAdmin III (the default GUI).

There are some other objects, the manual for GRANT has the complete list as of Postgres 12:

privileges on a database object (table, column, view, foreign table, sequence, database, foreign-data wrapper, foreign server, function, procedure, procedural language, schema, or tablespace)

But the rest is rarely needed. More details:

• How to manage DEFAULT PRIVILEGES for USERs on a DATABASE vs SCHEMA?
• Grant privileges for a particular database in PostgreSQL
• How to grant all privileges on views to arbitrary user

Consider upgrading to a current version.

This may be a lazy man's solution, but can't you just delete the contents of the index you want removed by reassigning their values to 0 or "" and then ignore/skip these empty array elements instead of recreating and copying arrays on and off?

<video id="myvideo">
  <source src="path/to/movie.mp4" />
</video>

<p onclick="toggleControls();">Toggle</p>

<script>
var video = document.getElementById("myvideo");

function toggleControls() {
  if (video.hasAttribute("controls")) {
     video.removeAttribute("controls")   
  } else {
     video.setAttribute("controls","controls")   
  }
}
</script>

See it working on jsFiddle: http://jsfiddle.net/dgLds/

One of the big uses for function pointers in C is to call a function selected at run-time. For example, the C run-time library has two routines, qsort and bsearch, which take a pointer to a function that is called to compare two items being sorted; this allows you to sort or search, respectively, anything, based on any criteria you wish to use.

A very basic example, if there is one function called print(int x, int y) which in turn may require to call a function (either add() or sub(), which are of the same type) then what we will do, we will add one function pointer argument to the print() function as shown below:

#include <stdio.h>

int add()
{
   return (100+10);
}

int sub()
{
   return (100-10);
}

void print(int x, int y, int (*func)())
{
    printf("value is: %d\n", (x+y+(*func)()));
}

int main()
{
    int x=100, y=200;
    print(x,y,add);
    print(x,y,sub);

    return 0;
}

The output is:

value is: 410
value is: 390

with navbar navbar-default everything works fine, but if you are using navbar-fixed-top you have to include custom style body { padding-top: 60px;} otherwise it will block content underneath.

As long as you're not doing any INSERT or UPDATE statements in your stored procedure, you will probably want to make it a function.

Stored procedures are for executing by an outside program, or on a timed interval.

The answers here will explain it better than I can:

Function vs. Stored Procedure in SQL Server

SQLServer 2008 now has a 'date' data type which contains only a date with no time component. Anyone using SQLServer 2008 and beyond can do the following:

SELECT CONVERT(date, GETDATE())

The Nan example above misses one piece, which makes it less generic. To do this more "generically" use df['column_name'].value_counts() This will give you the counts of each value in that column.

d=['A','A','A','B','C','C'," " ," "," "," "," ","-1"] # for simplicity

df=pd.DataFrame(d)
df.columns=["col1"]
df["col1"].value_counts() 
      5
A     3
C     2
-1    1
B     1
dtype: int64
"""len(df) give you 12, so we know the rest must be Nan's of some form, while also having a peek into other invalid entries, especially when you might want to ignore them like -1, 0 , "", also"""

To extract text from a PDF, try this on Linux, BSD, etc. machine or use Cygwin if on Windows:

pdfinfo -layout some_pdf_file.pdf

A plain text file named some_pdf_file.txt is created. The simpler the PDF file layout, the more straightforward the .txt file output will be.

Hexadecimal characters are frequently present in the .txt file output and will look strange in text editors. These hexadecimal characters usually represent curly single and double quotes, bullet points, hyphens, etc. in the PDF.

To see the context where the hexadecimal characters appear, run this grep command, and keep the original PDF handy to see what character the codes represent in the PDF:

grep -a --color=always "\\\\[0-9][0-9][0-9]" some_pdf_file.txt

This will provide a unique list of the different octal codes in the document:

grep -ao "\\\\[0-9][0-9][0-9]" some_pdf_file.txt|sort|uniq

To convert these hexadecimal characters to ASCII equivalents, a combination of grep, sed, and bc can be used, I'll post the procedure to do that soon.

NERDTree opens up in another window. That split view you're seeing? They're called windows in vim parlance. All the window commands start with CTRL-W. To move from adjacent windows that are left and right of one another, you can change focus to the window to the left of your current window with CTRL-w h, and move focus to the right with CTRL-w l. Likewise, CTRL-w j and CTRL-w k will move you between horizontally split windows (i.e., one window is above the other). There's a lot more you can do with windows as described here.

You can also use the :NERDTreeToggle command to make your tree open and close. I usually bind that do t.

Try this.

<script>

    var iframe = document.getElementById('i_frame');

    if (  iframeDoc.readyState  == 'complete' ) {
        //iframe.contentWindow.alert("Hello");
        iframe.contentWindow.onload = function(){
            alert("I am loaded");
        };
        // The loading is complete, call the function we want executed once the iframe is loaded
        afterLoading();
        return;
    } 

    // If we are here, it is not loaded. Set things up so we check   the status again in 100 milliseconds
    window.setTimeout(checkIframeLoaded, 100);
}

function afterLoading(){
    alert("I am here");
}

EDIT
In response to bendin's comment regarding encoding, see shsteimer's answer to this question.

Neither one is better in that they may be used for different purposes. onClick (should actually be onclick) performs very slightly better, but I highly doubt you will notice a difference there.

It is worth noting that they do different things: .click can be bound to any jQuery collection whereas onclick has to be used inline on the elements you want it to be bound to. You can also bind only one event to using onclick, whereas .click lets you continue to bind events.

In my opinion, I would be consistent about it and just use .click everywhere and keep all of my JavaScript code together and separated from the HTML.

Don't use onclick. There isn't any reason to use it unless you know what you're doing, and you probably don't.

React.createRef (class components)

class ClassApp extends React.Component {
  inputRef = React.createRef<HTMLInputElement>();
  
  render() {
    return <input type="text" ref={this.inputRef} />
  }
}

Note: Omitting the old String Refs legacy API here...

React.useRef (Hooks / function components)

const FunctionApp = () => {
  const inputRef = React.useRef<HTMLInputElement>(null) // note the passed in `null` arg
  return <input type="text" ref={inputRef} />
}

const FunctionApp = () => {
  const renderCountRef = useRef(0)
  useEffect(() => {
    renderCountRef.current += 1
  })
  // ... other render code
}

Note: Don't initialize useRef with null in this case. It would make the renderCountRef type readonly (see example). If you need to provide null as initial value, do this:

const renderCountRef = useRef<number | null>(null)

Callback refs (work for both)

// Function component example 
const FunctionApp = () => {
  const handleDomNodeChange = (domNode: HTMLInputElement | null) => {
    // ... do something with changed dom node.
  }
  return <input type="text" ref={handleDomNodeChange} />
}

Playground sample

check this link, in very simple via the convertView, we can get the layout of a row which will be displayed in listview (which is the parentView).

View v = convertView;

if (v == null) {

    LayoutInflater vi;
    vi = LayoutInflater.from(getContext());
    v = vi.inflate(R.layout.itemlistrow, null);

}

using the position, you can get the objects of the List<Item>.

Item p = items.get(position);

after that we'll have to set the desired details of the object to the identified form widgets.

if (p != null) {

    TextView tt = (TextView) v.findViewById(R.id.id);
    TextView tt1 = (TextView) v.findViewById(R.id.categoryId);
    TextView tt3 = (TextView) v.findViewById(R.id.description);

    if (tt != null) {
        tt.setText(p.getId());
    }
    if (tt1 != null) {

        tt1.setText(p.getCategory().getId());
    }
    if (tt3 != null) {

        tt3.setText(p.getDescription());
    }
}

then it will return the constructed view which will be attached to the parentView (which is a ListView/GridView).

I don't understand why people are seeding with a time value. This has in my experience never been a good idea. For example, while the system clock is maybe represented in nanoseconds, the system's clock precision isn't nanoseconds.

This program should not be run on the Go playground but if you run it on your machine you get a rough estimate on what type of precision you can expect. I see increments of about 1000000 ns, so 1 ms increments. That's 20 bits of entropy that are not used. All the while the high bits are mostly constant!? Roughly ~24 bits of entropy over a day which is very brute forceable (which can create vulnerabilities).

The degree that this matters to you will vary but you can avoid pitfalls of clock based seed values by simply using the crypto/rand.Read as source for your seed. It will give you that non-deterministic quality that you are probably looking for in your random numbers (even if the actual implementation itself is limited to a set of distinct and deterministic random sequences).

import (
    crypto_rand "crypto/rand"
    "encoding/binary"
    math_rand "math/rand"
)

func init() {
    var b [8]byte
    _, err := crypto_rand.Read(b[:])
    if err != nil {
        panic("cannot seed math/rand package with cryptographically secure random number generator")
    }
    math_rand.Seed(int64(binary.LittleEndian.Uint64(b[:])))
}

As a side note but in relation to your question. You can create your own rand.Source using this method to avoid the cost of having locks protecting the source. The rand package utility functions are convenient but they also use locks under the hood to prevent the source from being used concurrently. If you don't need that you can avoid it by creating your own Source and use that in a non-concurrent way. Regardless, you should NOT be reseeding your random number generator between iterations, it was never designed to be used that way.

aria-hidden="true" will hide decorative items like glyphicon icons from screen readers, which doesn't have meaningful pronunciation so as not to cause confusions. It's a nice thing do as matter of good practice.

Switch to AppCompatActivity and add a 25 dp paddingTop on the toolbar and turn on

<item name="android:windowTranslucentStatus">true</item>

Then, the will toolbar go up top the top

This one works for me.

`Post.find().sort({postedon: -1}).find(function (err, sortedposts){
    if (err) 
        return res.status(500).send({ message: "No Posts." });
    res.status(200).send({sortedposts : sortedposts});
 });`

Wait and await - while similar conceptually - are actually completely different.

Wait will synchronously block until the task completes. So the current thread is literally blocked waiting for the task to complete. As a general rule, you should use "async all the way down"; that is, don't block on async code. On my blog, I go into the details of how blocking in asynchronous code causes deadlock.

await will asynchronously wait until the task completes. This means the current method is "paused" (its state is captured) and the method returns an incomplete task to its caller. Later, when the await expression completes, the remainder of the method is scheduled as a continuation.

You also mentioned a "cooperative block", by which I assume you mean a task that you're Waiting on may execute on the waiting thread. There are situations where this can happen, but it's an optimization. There are many situations where it can't happen, like if the task is for another scheduler, or if it's already started or if it's a non-code task (such as in your code example: Wait cannot execute the Delay task inline because there's no code for it).

You may find my async / await intro helpful.

You would do something like that using Google API.

Please note you must include the google maps library for this to work. Google geocoder returns a lot of address components so you must make an educated guess as to which one will have the city.

"administrative_area_level_1" is usually what you are looking for but sometimes locality is the city you are after.

Anyhow - more details on google response types can be found here and here.

Below is the code that should do the trick:

    var lng = position.coords.longitude;
    codeLatLng(lat, lng)

}

  function initialize() {
    geocoder = new google.maps.Geocoder();



  }

  function codeLatLng(lat, lng) {

    var latlng = new google.maps.LatLng(lat, lng);
    geocoder.geocode({'latLng': latlng}, function(results, status) {

If you want to access a property from inside a class you should:

private $classNumber = 8;

More info about why it wasn't working for me in case it helps future people:

The reason why it wasn't working is that {% include %} in django doesn't like special characters like fancy apostrophe. The template data I was trying to include was pasted from word. I had to manually remove all of these special characters and then it included successfully.

Here is the latest simplest solution - no need to change anything, just add three lines of CSS rules to your container of the div where you wish to center at. I love Flex Box #LoveFlexBox

.main {_x000D_
  /* I changed height to 200px to make it easy to see the alignment. */_x000D_
  height: 200px;_x000D_
  vertical-align: middle;_x000D_
  border: 1px solid #000000;_x000D_
  padding: 2px;_x000D_
  _x000D_
  /* Just add the following three rules to the container of which you want to center at. */_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
  justify-content: center;_x000D_
  /* This is true vertical center, no math needed. */_x000D_
}_x000D_
.inner {_x000D_
  border: 1px solid #000000;_x000D_
}_x000D_
.second {_x000D_
  border: 1px solid #000000;_x000D_
}

<div class="main">_x000D_
  <div class="inner">This box should be centered in the larger box_x000D_
    <div class="second">Another box in here</div>_x000D_
  </div>_x000D_
  <div class="inner">This box should be centered in the larger box_x000D_
    <div class="second">Another box in here</div>_x000D_
  </div>_x000D_
</div>

Bonus

the justify-content value can be set to the following few options:

• flex-start, which will align the child div to where the flex flow starts in its parent container. In this case, it will stay on top.

• center, which will align the child div to the center of its parent container. This is really neat, because you don't need to add an additional div to wrap around all children to put the wrapper in a parent container to center the children. Because of that, this is the true vertical center (in the column flex-direction. similarly, if you change the flow-direction to row, it will become horizontally centered.

• flex-end, which will align the child div to where the flex flow ends in its parent container. In this case, it will move to bottom.

• space-between, which will spread all children from the beginning of the flow to the end of the flow. If the demo, I added another child div, to show they are spread out.

• space-around, similar to space-between, but with half of the space in the beginning and end of the flow.

Your query should work for synonyms as well as the tables. However, you seem to expect indexes on views where there are not. Maybe is it materialized views ?

You have to add options also in allowed headers. browser sends a preflight request before original request is sent. See below

 res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE,PATCH,OPTIONS');

From source https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/OPTIONS

In CORS, a preflight request with the OPTIONS method is sent, so that the server can respond whether it is acceptable to send the request with these parameters. The Access-Control-Request-Method header notifies the server as part of a preflight request that when the actual request is sent, it will be sent with a POST request method. The Access-Control-Request-Headers header notifies the server that when the actual request is sent, it will be sent with a X-PINGOTHER and Content-Type custom headers. The server now has an opportunity to determine whether it wishes to accept a request under these circumstances.

EDITED

You can avoid this manual configuration by using npmjs.com/package/cors npm package.I have used this method also, it is clear and easy.

java.time

Modern answer: use java.time, the modern Java date and time API, for your date and time work. Back in 2011 it was right to use the Timestamp class, but since JDBC 4.2 it is no longer advised.

For your work we need a time zone and a couple of formatters. We may as well declare them static:

static ZoneId zone = ZoneId.of("America/Marigot");
static DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern("MM/dd/uuuu");
static DateTimeFormatter timeFormatter = DateTimeFormatter.ofPattern("HH:mm xx");

Now the code could be for example:

    while(resultSet.next()) {
        ZonedDateTime dtStart = resultSet.getObject("dtStart", OffsetDateTime.class)
                 .atZoneSameInstant(zone);

        // I would like to then have the date and time
        // converted into the formats mentioned...
        String dateFormatted = dtStart.format(dateFormatter);
        String timeFormatted = dtStart.format(timeFormatter);
        System.out.format("Date: %s; time: %s%n", dateFormatted, timeFormatted);
    }

Example output (using the time your question was asked):

Date: 09/20/2011; time: 18:13 -0400

In your database timestamp with time zone is recommended for timestamps. If this is what you’ve got, retrieve an OffsetDateTime as I am doing in the code. I am also converting the retrieved value to the user’s time zone before formatting date and time separately. As time zone I supplied America/Marigot as an example, please supply your own. You may also leave out the time zone conversion if you don’t want any, of course.

If the datatype in SQL is a mere timestamp without time zone, retrieve a LocalDateTime instead. For example:

        ZonedDateTime dtStart = resultSet.getObject("dtStart", LocalDateTime.class)
                 .atZone(zone);

No matter the details I trust you to do similarly for dtEnd.

I wasn’t sure what you meant by the xx in HH:MM xx. I just left it in the format pattern string, which yields the UTC offset in hours and minutes without colon.

Unfortunately, there isn't an API to give you the HTTP response headers for your initial page request. That was the original question posted here. It has been repeatedly asked, too, because some people would like to get the actual response headers of the original page request without issuing another one.

For AJAX Requests:

If an HTTP request is made over AJAX, it is possible to get the response headers with the getAllResponseHeaders() method. It's part of the XMLHttpRequest API. To see how this can be applied, check out the fetchSimilarHeaders() function below. Note that this is a work-around to the problem that won't be reliable for some applications.

myXMLHttpRequest.getAllResponseHeaders();

• The API was specified in the following candidate recommendation for XMLHttpRequest: XMLHttpRequest - W3C Candidate Recommendation 3 August 2010

• Specifically, the getAllResponseHeaders() method was specified in the following section: w3.org: XMLHttpRequest: the getallresponseheaders() method

• The MDN documentation is good, too: developer.mozilla.org: XMLHttpRequest.

This will not give you information about the original page request's HTTP response headers, but it could be used to make educated guesses about what those headers were. More on that is described next.

Getting header values from the Initial Page Request:

This question was first asked several years ago, asking specifically about how to get at the original HTTP response headers for the current page (i.e. the same page inside of which the javascript was running). This is quite a different question than simply getting the response headers for any HTTP request. For the initial page request, the headers aren't readily available to javascript. Whether the header values you need will be reliably and sufficiently consistent if you request the same page again via AJAX will depend on your particular application.

The following are a few suggestions for getting around that problem.

1. Requests on Resources which are largely static

If the response is largely static and the headers are not expected to change much between requests, you could make an AJAX request for the same page you're currently on and assume that they're they are the same values which were part of the page's HTTP response. This could allow you to access the headers you need using the nice XMLHttpRequest API described above.

function fetchSimilarHeaders (callback) {
    var request = new XMLHttpRequest();
    request.onreadystatechange = function () {
        if (request.readyState === XMLHttpRequest.DONE) {
            //
            // The following headers may often be similar
            // to those of the original page request...
            //
            if (callback && typeof callback === 'function') {
                callback(request.getAllResponseHeaders());
            }
        }
    };

    //
    // Re-request the same page (document.location)
    // We hope to get the same or similar response headers to those which 
    // came with the current page, but we have no guarantee.
    // Since we are only after the headers, a HEAD request may be sufficient.
    //
    request.open('HEAD', document.location, true);
    request.send(null);
}

This approach will be problematic if you truly have to rely on the values being consistent between requests, since you can't fully guarantee that they are the same. It's going to depend on your specific application and whether you know that the value you need is something that won't be changing from one request to the next.

2. Make Inferences

There are some BOM properties (Browser Object Model) which the browser determines by looking at the headers. Some of these properties reflect HTTP headers directly (e.g. navigator.userAgent is set to the value of the HTTP User-Agent header field). By sniffing around the available properties you might be able to find what you need, or some clues to indicate what the HTTP response contained.

3. Stash them

If you control the server side, you can access any header you like as you construct the full response. Values could be passed to the client with the page, stashed in some markup or perhaps in an inlined JSON structure. If you wanted to have every HTTP request header available to your javascript, you could iterate through them on the server and send them back as hidden values in the markup. It's probably not ideal to send header values this way, but you could certainly do it for the specific value you need. This solution is arguably inefficient, too, but it would do the job if you needed it.

remove the ios::binary from your modes in your ofstream and use studentPassword.c_str() instead of (char *)&studentPassword in your write.write()

You have to use .values for arrays. for example say you have dataframe which has a column name ie, test['Name'], you can do

if name in test['Name'].values :
   print(name)

for a normal list you dont have to use .values

I think the selected answer is correct and pretty sweet. I implemented it differently though, as I also wanted the result in random order.

    static IEnumerable<SomeType> PickSomeInRandomOrder<SomeType>(
        IEnumerable<SomeType> someTypes,
        int maxCount)
    {
        Random random = new Random(DateTime.Now.Millisecond);

        Dictionary<double, SomeType> randomSortTable = new Dictionary<double,SomeType>();

        foreach(SomeType someType in someTypes)
            randomSortTable[random.NextDouble()] = someType;

        return randomSortTable.OrderBy(KVP => KVP.Key).Take(maxCount).Select(KVP => KVP.Value);
    }

Use onKeyDown event, and inside that check the key code of the key pressed by user. Key code of Enter key is 13, check the code and put the logic there.

Check this example:

class CartridgeShell extends React.Component {_x000D_
_x000D_
   constructor(props) {_x000D_
      super(props);_x000D_
      this.state = {value:''}_x000D_
_x000D_
      this.handleChange = this.handleChange.bind(this);_x000D_
      this.keyPress = this.keyPress.bind(this);_x000D_
   } _x000D_
 _x000D_
   handleChange(e) {_x000D_
      this.setState({ value: e.target.value });_x000D_
   }_x000D_
_x000D_
   keyPress(e){_x000D_
      if(e.keyCode == 13){_x000D_
         console.log('value', e.target.value);_x000D_
         // put the login here_x000D_
      }_x000D_
   }_x000D_
_x000D_
   render(){_x000D_
      return(_x000D_
         <input value={this.state.value} onKeyDown={this.keyPress} onChange={this.handleChange} fullWidth={true} />_x000D_
      )_x000D_
    }_x000D_
}_x000D_
_x000D_
ReactDOM.render(<CartridgeShell/>, document.getElementById('app'))

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>_x000D_
_x000D_
_x000D_
<div id = 'app' />

Note: Replace the input element by Material-Ui TextField and define the other properties also.

If you're using a NFS, "test" is a better solution, because you can add a timeout to it, in case your NFS is down:

time timeout 3 test -f 
/nfs/my_nfs_is_currently_down
real    0m3.004s <<== timeout is taken into account
user    0m0.001s
sys     0m0.004s
echo $?
124   <= 124 means the timeout has been reached

A "[ -e my_file ]" construct will freeze until the NFS is functional again:

if [ -e /nfs/my_nfs_is_currently_down ]; then echo "ok" else echo "ko" ; fi

<no answer from the system, my session is "frozen">

Here's a simple function I just wrote which reads a .hdf5 file generated by the save_weights function in keras and returns a dict with layer names and weights:

def read_hdf5(path):

    weights = {}

    keys = []
    with h5py.File(path, 'r') as f: # open file
        f.visit(keys.append) # append all keys to list
        for key in keys:
            if ':' in key: # contains data if ':' in key
                print(f[key].name)
                weights[f[key].name] = f[key].value
    return weights

Haven't tested it thoroughly but does the job for me.

For swift4 user:--

class TwoViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout, UICollectionViewDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

        self.collectionView = UICollectionView(frame: self.view.bounds, collectionViewLayout: flowLayout)
        collectionView.register(UICollectionViewCell.self, forCellWithReuseIdentifier: "collectionCell")
        collectionView.delegate = self
        collectionView.dataSource = self
        collectionView.backgroundColor = UIColor.cyan
        self.view.addSubview(collectionView)
    }

    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return 20
    }

    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
       var cell = collectionView.dequeueReusableCell(withReuseIdentifier: "collectionCell", for: indexPath as IndexPath)

       cell.backgroundColor = UIColor.green
       return cell
    }

    func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAtIndexPath indexPath: NSIndexPath) -> CGSize {
        return CGSize(width: 50, height: 50)
    }

    func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAtIndex section: Int) -> UIEdgeInsets {
        return UIEdgeInsets(top: 5, left: 5, bottom: 5, right: 5)
    }
}

When you echo $array;, the result is Array, result[0] then represents the first character in Array which is A.

One way to handle this problem would be like this:

ajax.php

<?php
$array = array(1,2,3,4,5,6);
foreach($array as $a)
    echo $a.",";
?>

jquery code

$(function(){ /* short for $(document).ready(function(){ */

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

        $.ajax({type:    'POST',
                 url:     'ajax.php',
                 data:    'id=testdata',
                 cache:   false,
                 success: function(data){
                     var tmp = data.split(",");
                     $('#content1').html(tmp[0]);
                 }
                });
    });

});

I am using texmaker as the editor. you have to compile it in terminal as following:

1. pdflatex filename (with or without extensions)
2. bibtex filename (without extensions)
3. pdflatex filename (with or without extensions)
4. pdflatex filename (with or without extensions)

but sometimes, when you use \citep{}, the names of the references don't show up. In this case, I had to open the references.bib file , so that texmaker could capture the references from the references.bib file. After every edition of the bib file, I had to close and reopen it!! So that texmaker could capture the content of new .bbl file each time. But remember, you have to also run your code in texmaker too.

The first thing to do would probably be to replace every mysql_* function call with its equivalent mysqli_*, at least if you are willing to use the procedural API -- which would be the easier way, considering you already have some code based on the MySQL API, which is a procedural one.

To help with that, the MySQLi Extension Function Summary is definitely something that will prove helpful.

For instance:

• mysql_connect will be replaced by mysqli_connect
• mysql_error will be replaced by mysqli_error and/or mysqli_connect_error, depending on the context
• mysql_query will be replaced by mysqli_query
• and so on

Note: For some functions, you may need to check the parameters carefully: Maybe there are some differences here and there -- but not that many, I'd say: both mysql and mysqli are based on the same library (libmysql ; at least for PHP <= 5.2)

For instance:

• with mysql, you have to use the mysql_select_db once connected, to indicate on which database you want to do your queries
• mysqli, on the other side, allows you to specify that database name as the fourth parameter to mysqli_connect.
• Still, there is also a mysqli_select_db function that you can use, if you prefer.

UITextAlignmentCenter is deprecated in iOS6

Instead you can use this code:

btn.titleLabel.textAlignment=NSTextAlinmentCenter;

In c++ (distant, dusty memory) I think it was a little easier to look at the code and understand arrays than it is in Java sometimes. Both are row major. This illustration worked for me in helping to understand.

Given this code for a 2d array of strings...

    String[][] messages; 
    messages = new String[][] {
        {"CAT","DOG","YIN","BLACK","HIGH","DAY"},
        {"kitten","puppy","yang","white","low","night"} 
    };
    
    int row = messages.length;
    int col = messages[0].length;
    

Naming my ints as if it were a 2d array (row, col) we see the values.

row = (int) 2
col = (int) 6

The last two lines of code, where we try to determine size and set them to row and col does not look all that intuitive and its not necessarily right.

What youre really dealing with here is this (note new variable names to illustrate):

int numOfArraysIn = messages.length;
int numOfElementsIn0 = messages[0].length;
int numOfElementsIn1 = messages[1].length;

Where messages.length tells you messages holds two arrays. An array of arrays.

AND then messages[x].length yields the size of each of the individual arrays 0 1 inside messages.

numOfArraysIn = (int) 2
numOfElementsIn0 = (int) 6
numOfElementsIn1 = (int) 6

When we print with a for each loop....

for (String str : messages[0])
        System.out.print(str);
for (String str : messages[1])
        System.out.print(str);

CATDOGYINBLACKHIGHDAYkittenpuppyyangwhitelownight

Trying to drop the brackets and print like this gives an error

for (String str : messages)
        System.out.print(str);

incompatible types: String[] cannot be converted to String

The above is important to understand while setting up loops that use .length to limit the step thru the array.

Add a reference to 'Microsoft.VisualStudio.QualityTools.UnitTestFramework" NuGet packet and it should successfully build it.

Actually, after waiting some time it eventually goes beyond that step. Even with --verbose, you won't have any information that it computes anything, but it does.

Patience is the key :)

PS : For anyone that cancelled at that step, if you try to reinstall the android-sdk package, it will complain that Error: No such file or directory - /usr/local/share/android-sdk. You can just touch /usr/local/share/android-sdk to get rid of that error and go on with the reinstall.
