One of the answers is that x:name is to be used inside different program languages such as c# and name is to be used for the framework. Honestly that is what it sounds like to me.

You may want to go look at the SQL Injection article on Wikipedia. Look under the "Hexadecimal Conversion" part to find a small function to do your SQL commands and return an array with the information in it.

https://en.wikipedia.org/wiki/SQL_injection

I wrote the dosql() function because I got tired of having my SQL commands executing all over the place, forgetting to check for errors, and being able to log all of my commands to a log file for later viewing if need be. The routine is free for whoever wants to use it for whatever purpose. I actually have expanded on the function a bit because I wanted it to do more but this basic function is a good starting point for getting the output back from an SQL call.

If you want to keep a small code base, and you are only going to be needing the toggle button for a small part of the application. I would suggest instead maintain you're javascript code your self (angularjs, javascript, jquery) and just use plain CSS.

Good toggle button generator: https://proto.io/freebies/onoff/

No. Its not possible to add link through css. But you can use jquery

$('.case').each(function() {
  var link = $(this).html();
  $(this).contents().wrap('<a href="example.com/script.php?id="></a>');
});

Here the demo: http://jsfiddle.net/r5uWX/1/

when reimporting your keys from the old keyring, you need to specify the command:

gpg --allow-secret-key-import --import <keyring>

otherwise it will only import the public keys, not the private keys.

The quintessential example of this is an array of pointers to structs or objects (that are mutable).

A shallow copy copies the array and maintains references to the original objects.

A deep copy will copy (clone) the objects too so they bear no relation to the original. Implicit in this is that the object themselves are deep copied. This is where it gets hard because there's no real way to know if something was deep copied or not.

The copy constructor is used to initilize the new object with the previously created object of the same class. By default compiler wrote a shallow copy. Shallow copy works fine when dynamic memory allocation is not involved because when dynamic memory allocation is involved then both objects will points towards the same memory location in a heap, Therefore to remove this problem we wrote deep copy so both objects have their own copy of attributes in a memory.

In order to read the details with complete examples and explanations you could see the article Constructors and destructors.

The default copy constructor is shallow. You can make your own copy constructors deep or shallow, as appropriate. See C++ Notes: OOP: Copy Constructors.

This might work out for you depending on which language you are using:

It's a positive lookbehind assertion. More information could be found here.

It won't work with JavaScript though. In your comment I read that you're using it for logstash. If you are using GROK parsing for logstash then it would work. You can verify it yourself here:

The best way is to copy all the files and folders inside a directory on your local file system by: docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH

SRC_PATH is on container DEST_PATH is on localhost

Then do docker-compose down attach a volume to the same DEST_PATH and run Docker containers by using docker-compose up -d

Add volume by following in docker-compose.yml

volumes:
 - DEST_PATH:SRC_PATH

Try using @Html.DropDownList instead:

<td>Account: </td>
<td>@Html.DropDownList("accountid", new SelectList(ViewBag.Accounts, "AccountID", "AccountName"))</td>

@Html.DropDownListFor expects a lambda as its first argument, not a string for the ID as you specify.

Other than that, without knowing what getUserAccounts() consists of, suffice to say it needs to return some sort of collection (IEnumerable for example) that has at least 1 object in it. If it returns null the property in the ViewBag won't have anything.

Celery is a distributed task queue, built on AMQP (RabbitMQ). It also handles periodic tasks in a cron-like fashion (see periodic tasks). Depending on your app, it might be worth a gander.

Celery is pretty easy to set up with django (docs), and periodic tasks will actually skip missed tasks in case of a downtime. Celery also has built-in retry mechanisms, in case a task fails.

Second case is also inefficient in terms of String pool, you have to explicitly call intern() on return reference to make it intern.

To simply answer your question when you do a mvn:install, maven will create a packaged artifact based on (packaging attribute in pom.xml), After you run your maven install you can find the file with .package extension

• In target directory of the project workspace
• Also where your maven 2 local repository is search for (.m2/respository) on your box, Your artifact is listed in .m2 repository under (groupId/artifactId/artifactId-version.packaging) directory
• If you look under the directory you will find packaged extension file and also pom extension (pom extension is basically the pom.xml used to generate this package)
• If your maven project is multi-module each module will two files as described above except for the top level project that will only have a pom

If You want make json object from yor model do like this :

  foreach (var item in Persons)
   {
    var jsonObj=["FirstName":"@item.FirstName"]
   }

Or Use Json.Net to make json from your model :

string json = JsonConvert.SerializeObject(person);

It's called and and or in Python.

I've successfully used int(x or 0) for this type of error, so long as None should equate to 0 in the logic. Note that this will also resolve to 0 in other cases where testing x returns False. e.g. empty list, set, dictionary or zero length string. Sorry, Kindall already gave this answer.

It does not matter where the variable comes from. Main thing we have one ... Set the variable name between square brackets "[ .. ]".

var optionName = 'nameA';
var JsonVar = {
[optionName] : 'some value'
}

It's probably easier to create your keys under linux and use PuTTYgen to convert the keys to PuTTY format.

Consider the following code:

public String removeChar(String str, Integer n) {
    String front = str.substring(0, n);
    String back = str.substring(n+1, str.length());
    return front + back;
}

Based on kynan's answer, here are the same aliases, modified so they can handle spaces and initial dashes in filenames:

accept-ours = "!f() { [ -z \"$@\" ] && set - '.'; git checkout --ours -- \"$@\"; git add -u -- \"$@\"; }; f"
accept-theirs = "!f() { [ -z \"$@\" ] && set - '.'; git checkout --theirs -- \"$@\"; git add -u -- \"$@\"; }; f"

I'm posting this answer with the hope of someone sharing with me if and why it would be a bad idea. In my application, I have a property of Type that I want to check to be sure it is typeof(A) or typeof(B), where B is any class derived from A. So my code:

public class A
{
}

public class B : A
{
}

public class MyClass
{
    private Type _helperType;
    public Type HelperType
    {
        get { return _helperType; }
        set 
        {
            var testInstance = (A)Activator.CreateInstance(value);
            if (testInstance==null)
                throw new InvalidCastException("HelperType must be derived from A");
            _helperType = value;
        }
    }
}

I feel like I might be a bit naive here so any feedback would be welcome.

Try this for a friendly representation of time differences (in milliseconds):

String friendlyTimeDiff(long timeDifferenceMilliseconds) {
    long diffSeconds = timeDifferenceMilliseconds / 1000;
    long diffMinutes = timeDifferenceMilliseconds / (60 * 1000);
    long diffHours = timeDifferenceMilliseconds / (60 * 60 * 1000);
    long diffDays = timeDifferenceMilliseconds / (60 * 60 * 1000 * 24);
    long diffWeeks = timeDifferenceMilliseconds / (60 * 60 * 1000 * 24 * 7);
    long diffMonths = (long) (timeDifferenceMilliseconds / (60 * 60 * 1000 * 24 * 30.41666666));
    long diffYears = timeDifferenceMilliseconds / ((long)60 * 60 * 1000 * 24 * 365);

    if (diffSeconds < 1) {
        return "less than a second";
    } else if (diffMinutes < 1) {
        return diffSeconds + " seconds";
    } else if (diffHours < 1) {
        return diffMinutes + " minutes";
    } else if (diffDays < 1) {
        return diffHours + " hours";
    } else if (diffWeeks < 1) {
        return diffDays + " days";
    } else if (diffMonths < 1) {
        return diffWeeks + " weeks";
    } else if (diffYears < 1) {
        return diffMonths + " months";
    } else {
        return diffYears + " years";
    }
}

For me texBoxName.Clear();is the best method because I have textboxs in binding and if I use other methods I do not have a good day

For starters:

<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.

This would be the optimal solution:

<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Since this is the first Google result for 'pandas new column from others', here's a simple example:

import pandas as pd

# make a simple dataframe
df = pd.DataFrame({'a':[1,2], 'b':[3,4]})
df
#    a  b
# 0  1  3
# 1  2  4

# create an unattached column with an index
df.apply(lambda row: row.a + row.b, axis=1)
# 0    4
# 1    6

# do same but attach it to the dataframe
df['c'] = df.apply(lambda row: row.a + row.b, axis=1)
df
#    a  b  c
# 0  1  3  4
# 1  2  4  6

If you get the SettingWithCopyWarning you can do it this way also:

fn = lambda row: row.a + row.b # define a function for the new column
col = df.apply(fn, axis=1) # get column data with an index
df = df.assign(c=col.values) # assign values to column 'c'

Source: https://stackoverflow.com/a/12555510/243392

And if your column name includes spaces you can use syntax like this:

df = df.assign(**{'some column name': col.values})

And here's the documentation for apply, and assign.

well i found a solution to this problem for who want to work with xCode 4. All what you have to do is importing frameworks from the SimulatorSDK folder /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/System/Library/Frameworks

i don't know if it works when you try to test your app on a real iDevice, but i'm sure that it works on simulator.

One should ask why you would want a public getter method for the password. Hibernate, or any other ORM framework, will do with a private getter method. For checking whether the password is correct, you can use

public boolean checkPassword(String password){
  return this.password.equals(anyHashingMethod(password));
}

I know this is old but I had a similar need for this and I did not want to do the find and replace version. It turns out that you can nest the substitute method like so:

=SUBSTITUTE(SUBSTITUTE(F149, "a", " AM"), "p", " PM")

In my case, I am using excel to view a DBF file and however it was populated has times like this:

9:16a
2:22p

So I just made a new column and put that formula in it to convert it to the excel time format.

While the others answers are correct in so far as they show what a mere + usually does (namely, leave the number as it is, if it is one), they are incomplete in so far as they don't explain what happens.

To be exact, +x evaluates to x.__pos__() and ++x to x.__pos__().__pos__().

I could imagine a VERY weird class structure (Children, don't do this at home!) like this:

class ValueKeeper(object):
    def __init__(self, value): self.value = value
    def __str__(self): return str(self.value)

class A(ValueKeeper):
    def __pos__(self):
        print 'called A.__pos__'
        return B(self.value - 3)

class B(ValueKeeper):
    def __pos__(self):
        print 'called B.__pos__'
        return A(self.value + 19)

x = A(430)
print x, type(x)
print +x, type(+x)
print ++x, type(++x)
print +++x, type(+++x)

As @PavelAnossov answered, the canonical answer, use the word_tokenize function in nltk:

from nltk import word_tokenize
sent = "This is my text, this is a nice way to input text."
word_tokenize(sent)

If your sentence is truly simple enough:

Using the string.punctuation set, remove punctuation then split using the whitespace delimiter:

import string
x = "This is my text, this is a nice way to input text."
y = "".join([i for i in x if not in string.punctuation]).split(" ")
print y

I also found another useful way of doing this in the case you are using a UITableview (which is a subclass of UIScrollView):

[(UITableView *)self.view scrollToRowAtIndexPath:scrollIndexPath atScrollPosition:UITableViewScrollPositionBottom animated:YES];

you can use RabbitMQ API to get count or messages :

/api/queues/vhost/name/get

Get messages from a queue. (This is not an HTTP GET as it will alter the state of the queue.) You should post a body looking like:

{"count":5,"requeue":true,"encoding":"auto","truncate":50000}

count controls the maximum number of messages to get. You may get fewer messages than this if the queue cannot immediately provide them.

requeue determines whether the messages will be removed from the queue. If requeue is true they will be requeued - but their redelivered flag will be set. encoding must be either "auto" (in which case the payload will be returned as a string if it is valid UTF-8, and base64 encoded otherwise), or "base64" (in which case the payload will always be base64 encoded). If truncate is present it will truncate the message payload if it is larger than the size given (in bytes). truncate is optional; all other keys are mandatory.

Please note that the publish / get paths in the HTTP API are intended for injecting test messages, diagnostics etc - they do not implement reliable delivery and so should be treated as a sysadmin's tool rather than a general API for messaging.

How about a Bash Here Document:

ssh otherhost << EOF
  ls some_folder; 
  ./someaction.sh 'some params'
  pwd
  ./some_other_action 'other params'
EOF

To avoid the problems mentioned by @Globalz in the comments, you may be able to (depending what you're doing on the remote site) get away with replacing the first line with

ssh otherhost /bin/bash << EOF

Note that you can do variable substitution in the Here document, but you may have to deal with quoting issues. For instance, if you quote the "limit string" (ie. EOF in the above), then you can't do variable substitutions. But without quoting the limit string, variables are substituted. For example, if you have defined $NAME above in your shell script, you could do

ssh otherhost /bin/bash << EOF
touch "/tmp/${NAME}"
EOF

and it would create a file on the destination otherhost with the name of whatever you'd assigned to $NAME. Other rules about shell script quoting also apply, but are too complicated to go into here.

Some versions of Android support custom Activity transitions and some don't (older devices). If you want to use custom transitions it's good practice to check whether the Activity has the overridePendingTransition() method, as on older versions it does not.

To know whether the method exists or not, reflection API can be used. Here is the simple code which will check and return the method if it exists:

Method mOverridePendingTransition;

try {
        mOverridePendingTransition = Activity.class.getMethod(
                "overridePendingTransition", new Class[] { Integer.TYPE, Integer.TYPE } );
        /* success */
    } catch (NoSuchMethodException nsme) {
        /* failure, this version of Android doesn't have this method */
    } 

And then, we can apply our own transition, i.e. use this method if it exists:

if (UIConstants.mOverridePendingTransition != null) {
               try {
                   UIConstants.mOverridePendingTransition.invoke(MainActivity.this, R.anim.activity_fade_in, R.anim.activity_fade_out);
               } catch (InvocationTargetException e) {
                   e.printStackTrace();
               } catch (IllegalAccessException e) {
                   e.printStackTrace();
               }
            }

Here, as an example, simple fade-in and fade-out animations were used for transition demonstration..

Assuming that I is your input image and F is its Fourier Transform (i.e. F = fft2(I))

You can use this code:

F = fftshift(F); % Center FFT

F = abs(F); % Get the magnitude
F = log(F+1); % Use log, for perceptual scaling, and +1 since log(0) is undefined
F = mat2gray(F); % Use mat2gray to scale the image between 0 and 1

imshow(F,[]); % Display the result

You are passing wrong mode to you view. Your view is looking for @model IEnumerable<Standings.Models.Teams> and you are passing var model = tm.Name.ToList(); name list. You have to pass list of Teams.

You have to pass following model

var model = new List<Teams>();

model.Add(new Teams { Name =  new List<string>(){"Sky","ABC"}});
model.Add(new Teams { Name =  new List<string>(){"John","XYZ"} });
return View(model);

I am using this function to tryparse

public static bool TryParseSqlDateTime(string someval, DateTimeFormatInfo dateTimeFormats, out DateTime tryDate)
    {
        bool valid = false;
        tryDate = (DateTime)System.Data.SqlTypes.SqlDateTime.MinValue;
        System.Data.SqlTypes.SqlDateTime sdt;
        if (DateTime.TryParse(someval, dateTimeFormats, DateTimeStyles.None, out tryDate))
        {
            try
            {
                sdt = new System.Data.SqlTypes.SqlDateTime(tryDate);
                valid = true;
            }
            catch (System.Data.SqlTypes.SqlTypeException ex)
            {

            }
        }

        return valid;
    }

Since this is a popular question, I would like to add that in Elasticsearch version 2 things changed a bit.

Instead of filtered query, one should use bool query in the top level.

If you don't care about the score of must parts, then put those parts into filter key. No scoring means faster search. Also, Elasticsearch will automatically figure out, whether to cache them, etc. must_not is equally valid for caching.

Reference: https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-bool-query.html

Also, mind that "gte": "now" cannot be cached, because of millisecond granularity. Use two ranges in a must clause: one with now/1h and another with now so that the first can be cached for a while and the second for precise filtering accelerated on a smaller result set.

I tried doing all the above and no luck. I downloaded the latest .net core 2.0 package and ran the commands again and it worked.

I use uploaded images on my website and I would definitely say option a).

One other thing I'd highly recommend is immediately changing the file name from what the user has named the photo, to something more manageable. For example something with the date and time to uniquely identify each picture.

It also helps to strip the user's file name of any strange characters to avoid future complications.

Long story short, node draws from V8, which is internally single-threaded. There are ways to work around the constraints for CPU-intensive tasks.

At one point (0.7) the authors tried to introduce isolates as a way of implementing multiple threads of computation, but were ultimately removed: https://groups.google.com/forum/#!msg/nodejs/zLzuo292hX0/F7gqfUiKi2sJ

parseInt converts to a integer number, that is, it strips decimals. Number does not convert to integer.

Adapting the PATH should work. Just tried on my Git bash:

$ python --version
sh.exe": python: command not found

$ PATH=$PATH:/c/Python27/

$ python --version
Python 2.7.6

In particular, only provide the directory; don't specify the .exe on the PATH ; and use slashes.

I know this is an old question, but I have just had a similar problem and I think what I did would work for you too.

I used the to_csv() method and wrote to stdout:

import sys

paramdata.to_csv(sys.stdout)

This should dump the whole dataframe whether it's nicely-printable or not, and you can use the to_csv parameters to configure column separators, whether the index is printed, etc.

Edit: It is now possible to use None as the target for .to_csv() with similar effect, which is arguably a lot nicer:

paramdata.to_csv(None)

Maybe you should try this: intent.setType("plain/text");

I found it here. I've used it in my app and it shows only E-Mail and Gmail options.

You can have multiple sizes of icons in the same file. I routinely create favicons (.ico file) that are 48, 32, and 16 pixels. You can add in any size image you want. The question is, will the iPhone use an ico file?

ico also supports transparency, but I'm not sure if it's an alpha channel like PNG; probably more like GIF where it's on or it's off.

If you are trying to access an html element: this is an HTML Anchor...

My nav bar has items that are not list items (<li>) but rather html anchors (<a>)

See below: (This is the site master)

<nav class="mdl-navigation">
    <a class="mdl-navigation__link" href="" runat="server" id="liHome">Home</a>
    <a class="mdl-navigation__link" href="" runat="server" id="liDashboard">Dashboard</a>
</nav>

Now in your code behind for another page, for mine, it's the login page...

On PageLoad() define this:

HtmlAnchor lblMasterStatus = (HtmlAnchor)Master.FindControl("liHome");
lblMasterStatus.Visible =false;

HtmlAnchor lblMasterStatus1 = (HtmlAnchor)Master.FindControl("liDashboard");
lblMasterStatus1.Visible = false;

Now we have accessed the site masters controls, and have made them invisible on the login page.

for utf8 str:

function unicodeStrDigits($str) {
    $arr = array();
    $sub = '';
    for ($i = 0; $i < strlen($str); $i++) { 
        if (is_numeric($str[$i])) {
            $sub .= $str[$i];
            continue;
        } else {
            if ($sub) {
                array_push($arr, $sub);
                $sub = '';
            }
        }
    }

    if ($sub) {
        array_push($arr, $sub); 
    }

    return $arr;
}

You can use readstream and pipe to read the file line by line without read all the file into memory one time.

var fs = require('fs'),
    es = require('event-stream'),
    os = require('os');

var s = fs.createReadStream(path)
    .pipe(es.split())
    .pipe(es.mapSync(function(line) {
        //pause the readstream
        s.pause();
        console.log("line:", line);
        s.resume();
    })
    .on('error', function(err) {
        console.log('Error:', err);
    })
    .on('end', function() {
        console.log('Finish reading.');
    })
);

How about the following one? Should allow you to use either raw_input or input in both Python2 and Python3 with the semantics of Python2's raw_input (aka the semantics of Python3's input)

# raw_input isn't defined in Python3.x, whereas input wasn't behaving like raw_input in Python 2.x
# this should make both input and raw_input work in Python 2.x/3.x like the raw_input from Python 2.x 
try: input = raw_input
except NameError: raw_input = input

You can move Application.java to a folder under the java.

Config file:

worker_processes  4;  # 2 * Number of CPUs

events {
    worker_connections  19000;  # It's the key to high performance - have a lot of connections available
}

worker_rlimit_nofile    20000;  # Each connection needs a filehandle (or 2 if you are proxying)


# Total amount of users you can serve = worker_processes * worker_connections

Your code attempts to overwrite a string literal. This is undefined behaviour.

There are several ways to fix this:

1. use malloc() then strcpy() then free();
2. turn str into an array and use strcpy();
3. use strdup().

man your container is 40% of the width of the parent element

but when you use position:fixed, the width is based on viewport(document) width...

thinking about, i realized your parent element have 10% padding(left and right), it means your element have 80% of the total page width. so your fixed element must have 40% based on 80% of total width

so you just need to change your #fixed class to

#fixed{ 
    position:fixed;
    width: calc(80% * 0.4);
    height:10px;
    background-color:#333;
}

if you use sass, postcss or another css compiler, you can use variables to avoid breaking the layout when you change the padding value of parent element.

I agree with rpd, this is the answer and can be done on a regular basis to clean up your id column that is getting bigger with only a few hundred rows of data, but maybe an id of 34444543!, as the data is deleted out regularly but id is incremented automatically.

ALTER TABLE users DROP id

The above sql can be run via sql query or as php. This will delete the id column.

Then re add it again, via the code below:

ALTER TABLE  `users` ADD `id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY FIRST

Place this in a piece of code that may get run maybe in an admin panel, so when anyone enters that page it will run this script that auto cleans your database, and tidys it.

You already have an old copy of that database installed in Server Explorer. So its a simple naming collision in the Server Object Explorer / SQL server. You likely created the same database Catalog Name already before you decided to move it to the Apps_Data folder. So that Database name already exists and just needs to be deleted.

Just go into Visual Studio > View > SQL Server Object Explorer and delete the old database name and its connection. Retry your app again and it should install the .mdf file in App_Data and create the same exact database again in the Server Explorer.

If you happen to be using numpy (with import numpy as np):

In [24]: x
Out[24]: array([1, 2, 3, 4, 5])

In [25]: np.dot(x, 10**np.arange(len(x)-1, -1, -1))
Out[25]: 12345

In case anyone are still interested in this subject, I find that the best approach for filtering lists is to create a generic Filter class and use it with some base reflection/generics techniques contained in the Java old school SDK package. Here's what I did:

public class GenericListFilter<T> extends Filter {

    /**
     * Copycat constructor
     * @param list  the original list to be used
     */
    public GenericListFilter (List<T> list, String reflectMethodName, ArrayAdapter<T> adapter) {
        super ();

        mInternalList = new ArrayList<>(list);
        mAdapterUsed  = adapter;

        try {
            ParameterizedType stringListType = (ParameterizedType)
                    getClass().getField("mInternalList").getGenericType();
            mCompairMethod =
                    stringListType.getActualTypeArguments()[0].getClass().getMethod(reflectMethodName);
        }
        catch (Exception ex) {
            Log.w("GenericListFilter", ex.getMessage(), ex);

            try {
                if (mInternalList.size() > 0) {
                    T type = mInternalList.get(0);
                    mCompairMethod = type.getClass().getMethod(reflectMethodName);
                }
            }
            catch (Exception e) {
                Log.e("GenericListFilter", e.getMessage(), e);
            }

        }
    }

    /**
     * Let's filter the data with the given constraint
     * @param constraint
     * @return
     */
    @Override protected FilterResults performFiltering(CharSequence constraint) {
        FilterResults results = new FilterResults();
        List<T> filteredContents = new ArrayList<>();

        if ( constraint.length() > 0 ) {
            try {
                for (T obj : mInternalList) {
                    String result = (String) mCompairMethod.invoke(obj);
                    if (result.toLowerCase().startsWith(constraint.toString().toLowerCase())) {
                        filteredContents.add(obj);
                    }
                }
            }
            catch (Exception ex) {
                Log.e("GenericListFilter", ex.getMessage(), ex);
            }
        }
        else {
            filteredContents.addAll(mInternalList);
        }

        results.values = filteredContents;
        results.count  = filteredContents.size();
        return results;
    }

    /**
     * Publish the filtering adapter list
     * @param constraint
     * @param results
     */
    @Override protected void publishResults(CharSequence constraint, FilterResults results) {
        mAdapterUsed.clear();
        mAdapterUsed.addAll((List<T>) results.values);

        if ( results.count == 0 ) {
            mAdapterUsed.notifyDataSetInvalidated();
        }
        else {
            mAdapterUsed.notifyDataSetChanged();
        }
    }

    // class properties
    private ArrayAdapter<T> mAdapterUsed;
    private List<T> mInternalList;
    private Method  mCompairMethod;
}

And afterwards, the only thing you need to do is to create the filter as a member class (possibly within the View's "onCreate") passing your adapter reference, your list, and the method to be called for filtering:

this.mFilter = new GenericFilter<MyObjectBean> (list, "getName", adapter);

The only thing missing now, is to override the "getFilter" method in the adapter class:

@Override public Filter getFilter () {
     return MyViewClass.this.mFilter;
}

All done! You should successfully filter your list - Of course, you should also implement your filter algorithm the best way that describes your need, the code bellow is just an example.. Hope it helped, take care.

I know this is very old and possibly talking about an older version of Visual studio and so this might not have been an option before but anyway, my way would be when at a breakpoint use the locals window to see all current variable values ( Debug >> Windows >> Locals )

Please try CURRENT_TIME() or now() functions

"INSERT INTO contactinfo (name, email, subject, date, comments)
VALUES ('$name', '$email', '$subject', NOW(), '$comments')"

OR

"INSERT INTO contactinfo (name, email, subject, date, comments)
VALUES ('$name', '$email', '$subject', CURRENT_TIME(), '$comments')"

OR you could try with PHP date function here:

$date = date("Y-m-d H:i:s");

Add the css styling text-align: center to the control.

Ideally you would do this through a css class assigned to the control, but if you must do it directly, here is an example:

<asp:TextBox ID="myTextBox" runat="server" style="text-align: center"></asp:TextBox>

I had similar issue with <input type="range" /> and I solved it with

-webkit-tap-highlight-color: transparent;

input[type="range"]{
  -webkit-tap-highlight-color: transparent;
}

 <input type="range" id="volume" name="demo"
         min="0" max="11">
  <label for="volume">Demo</label>

I believe this is a MinGW/gcc compiler issue, rather than a Microsoft Visual Studio setup.

The libgcc_s_dw2-1.dll should be in the compiler's bin directory. You can add this directory to your PATH environment variable for runtime linking, or you can avoid the problem by adding "-static-libgcc -static-libstdc++" to your compiler flags.

If you plan to distribute the executable, the latter probably makes the most sense. If you only plan to run it on your own machine, the changing the PATH environment variable is an attractive option (keeps down the size of the executable).

Updated:

Based on feedback from Greg Treleaven (see comments below), I'm adding links to:

[Screenshot of Code::Blocks "Project build options"]

[GNU gcc link options]

The latter discussion includes -static-libgcc and -static-libstdc++ linker options.

the values you set determine the order that your keyboard focus will move between elements on the website.

In the following example, the first time you press tab, your cursor will move to #foo, then #awesome, then #bar

<input id="foo" tabindex="1"  />
<input id="bar" tabindex="3"  />
<input id="awesome" tabindex="2"  />

If you have not defined tab indexes anywhere, the keyboard focus will follow the HTML tags of you page in the order in which they are defined in the HTML document.

If you tab more times than you have specified tabindexes for, the focus will move as if there were no tabindexes, i.e. in the order of appearance of the HTML tags

If you have added test.c to your Code::Blocks project, the definition will be seen twice - once via the #include and once by the linker. You need to:

• remove the #include "test.c"
• create a file test.h which contains the declaration: void test();

• include the file test.h in main.c

To expand on the "use JAXB" comments above,

In Windows "%java_home%\bin\xjc" -p [your namespace] [xsd_file].xsd

e.g., "%java_home%\bin\xjc" -p com.mycompany.quickbooks.obj quickbooks.xsd

Wait a bit, and if you had a well-formed XSD file, you will get some well-formed Java classes

I got same error because I was trying to run on

XXX-Macmini:Python-Project XXX.XXX$ from classDemo import MyClass

from: can't read /var/mail/classDemo

To solve this, type command python and when you get these >>> then run any python commands

>>>from classDemo import MyClass
>>>f = MyClass()

Also you should note that if your project is consist of several modules which are dependent on each other, you should use "install" instead of "package", otherwise your build will fail, cause when you use install command, module A will be packaged and deployed to local repository and then if module B needs module A as a dependency, it can access it from local repository.

Why would UPDLOCK block selects? The Lock Compatibility Matrix clearly shows N for the S/U and U/S contention, as in No Conflict.

As for the HOLDLOCK hint the documentation states:

HOLDLOCK: Is equivalent to SERIALIZABLE. For more information, see SERIALIZABLE later in this topic.

...

SERIALIZABLE: ... The scan is performed with the same semantics as a transaction running at the SERIALIZABLE isolation level...

and the Transaction Isolation Level topic explains what SERIALIZABLE means:

No other transactions can modify data that has been read by the current transaction until the current transaction completes.

Other transactions cannot insert new rows with key values that would fall in the range of keys read by any statements in the current transaction until the current transaction completes.

Therefore the behavior you see is perfectly explained by the product documentation:

• UPDLOCK does not block concurrent SELECT nor INSERT, but blocks any UPDATE or DELETE of the rows selected by T1
• HOLDLOCK means SERALIZABLE and therefore allows SELECTS, but blocks UPDATE and DELETES of the rows selected by T1, as well as any INSERT in the range selected by T1 (which is the entire table, therefore any insert).
• (UPDLOCK, HOLDLOCK): your experiment does not show what would block in addition to the case above, namely another transaction with UPDLOCK in T2:
  SELECT * FROM dbo.Test WITH (UPDLOCK) WHERE ...
• TABLOCKX no need for explanations

The real question is what are you trying to achieve? Playing with lock hints w/o an absolute complete 110% understanding of the locking semantics is begging for trouble...

After OP edit:

I would like to select rows from a table and prevent the data in that table from being modified while I am processing it.

The you should use one of the higher transaction isolation levels. REPEATABLE READ will prevent the data you read from being modified. SERIALIZABLE will prevent the data you read from being modified and new data from being inserted. Using transaction isolation levels is the right approach, as opposed to using query hints. Kendra Little has a nice poster exlaining the isolation levels.

You are encoding to UTF-8, then re-encoding to UTF-8. Python can only do this if it first decodes again to Unicode, but it has to use the default ASCII codec:

>>> u'ñ'
u'\xf1'
>>> u'ñ'.encode('utf8')
'\xc3\xb1'
>>> u'ñ'.encode('utf8').encode('utf8')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128)

Don't keep encoding; leave encoding to UTF-8 to the last possible moment instead. Concatenate Unicode values instead.

You can use str.join() (or, rather, unicode.join()) here to concatenate the three values with dashes in between:

nombre = u'-'.join(fabrica, sector, unidad)
return nombre.encode('utf-8')

but even encoding here might be too early.

Rule of thumb: decode the moment you receive the value (if not Unicode values supplied by an API already), encode only when you have to (if the destination API does not handle Unicode values directly).

An example would be

In Oracle you can use LISTAGG aggregate function.

Original records

name   type
------------
name1  type1
name2  type2
name2  type3

Sql

SELECT name, LISTAGG(type, '; ') WITHIN GROUP(ORDER BY name)
FROM table
GROUP BY name

Result in

name   type
------------
name1  type1
name2  type2; type3

The asterisk (*) means "zero or more of the previous item".

If you want to match any single character use

sed -i 's/string-./string-0/g' file.txt

If you want to match any string (i.e. any single character zero or more times) use

sed -i 's/string-.*/string-0/g' file.txt

You may come across code that reads from an InputStream and uses the snippet while(in.available()>0) to check for the end of the stream, rather than checking for an EOFException (end of the file).

The problem with this technique, and the Javadoc does echo this, is that it only tells you the number of blocks that can be read without blocking the next caller. In other words, it can return 0 even if there are more bytes to be read. Therefore, the InputStream available() method should never be used to check for the end of the stream.

You must use while (true) and

catch(EOFException e) {
//This isn't problem
} catch (Other e) {
//This is problem
}

I strongly suspect that's because of the network connection or the web server you're talking to - it's not BufferedReader's fault. Try measuring this:

InputStream stream = conn.getInputStream();
byte[] buffer = new byte[1000];
// Start timing
while (stream.read(buffer) > 0)
{
}
// End timing

I think you'll find it's almost exactly the same time as when you're parsing the text.

Note that you should also give InputStreamReader an appropriate encoding - the platform default encoding is almost certainly not what you should be using.

If the issue is font getting too big on widescreen desktop, I think the easiest CSS method would be something like this (assuming wrapper maximum 1000 pixels wide)

.specialText{
    font-size: 2.4vw;
}

@media only screen and (min-width: 1000px) {
    .specialText {
        width: 24px;
    }
}

So it is auto sized for any screen smaller than the maximum width of your container, and fixed size when the screen is wider (like virtually all desktop and laptops).

If:

X is image width,
Y is image height,

then:

img {
    position: absolute;
    top: 50%;
    left: 50%;
    margin-left: -(X/2)px;
    margin-top: -(Y/2)px;
}

But keep in mind this solution is valid only if the only element on your site will be this image. I suppose that's the case here.

Using this method gives you the benefit of fluidity. It won't matter how big (or small) someone's screen is. The image will always stay in the middle.

For jQuery version < 1.9:

$('#inputId').attr('disabled', true);

For jQuery version >= 1.9:

$('#inputId').prop('disabled', true);

Just an idea, if you know the categories, as small, medium, and large mentioned above...

At the bottom of the sheet, make 3 rows that only say small, medium, and large, change the font to white, and then sort so that it alphabetizes, placing a blank row between each section.

A cleaner way to accomplish this is by providing an initial value:

var arr = [{x:1}, {x:2}, {x:4}];_x000D_
arr.reduce(function (acc, obj) { return acc + obj.x; }, 0); // 7_x000D_
console.log(arr);

The first time the anonymous function is called, it gets called with (0, {x: 1}) and returns 0 + 1 = 1. The next time, it gets called with (1, {x: 2}) and returns 1 + 2 = 3. It's then called with (3, {x: 4}), finally returning 7.

I also had problem understanding next() , but this helped

var app = require("express")();

app.get("/", function(httpRequest, httpResponse, next){
    httpResponse.write("Hello");
    next(); //remove this and see what happens 
});

app.get("/", function(httpRequest, httpResponse, next){
    httpResponse.write(" World !!!");
    httpResponse.end();
});

app.listen(8080);

Keeping the code simple is always my advice:

If IsNull(Me.Id) = True Then
  DoCmd.GoToRecord , , acNext
Else
  DoCmd.GoToRecord , , acLast
End If

You can use

String [] strArr = Str.split("");

I think all solutions will fail if the length of the replacing string is different from the length of the string to be replaced. (search for "abc" and replace by "xxxxxx") A general approach might be:

void replaceAll( string &s, const string &search, const string &replace ) {
    for( size_t pos = 0; ; pos += replace.length() ) {
        // Locate the substring to replace
        pos = s.find( search, pos );
        if( pos == string::npos ) break;
        // Replace by erasing and inserting
        s.erase( pos, search.length() );
        s.insert( pos, replace );
    }
}

var data =   {"values": [
    {"name":0,"value":0.12791263050161572},
    {"name":1,"value":0.13158780927382124}
]};

//JSON to string conversion
var a = JSON.stringify(data);
// replace all name with "x"- global matching
var t = a.replace(/name/g,"x"); 
// replace exactly the value rather than all values
var d = t.replace(/"value"/g, '"y"');
// String to JSON conversion
var data = JSON.parse(d);

text = "just trying out"

word_list = []

for i in range(0, len(text)):
    word_list.append(text[i])
    i+=1

print(word_list)

['j', 'u', 's', 't', ' ', 't', 'r', 'y', 'i', 'n', 'g', ' ', 'o', 'u', 't']

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

This worked for me for a format like YYYY.MM.DD-HH.MM.SS.fff. Attempting to make this code capable of accepting any string format will be like reinventing the wheel (i.e. there are functions for all this in Boost.

std::chrono::system_clock::time_point string_to_time_point(const std::string &str)
{
    using namespace std;
    using namespace std::chrono;

    int yyyy, mm, dd, HH, MM, SS, fff;

    char scanf_format[] = "%4d.%2d.%2d-%2d.%2d.%2d.%3d";

    sscanf(str.c_str(), scanf_format, &yyyy, &mm, &dd, &HH, &MM, &SS, &fff);

    tm ttm = tm();
    ttm.tm_year = yyyy - 1900; // Year since 1900
    ttm.tm_mon = mm - 1; // Month since January 
    ttm.tm_mday = dd; // Day of the month [1-31]
    ttm.tm_hour = HH; // Hour of the day [00-23]
    ttm.tm_min = MM;
    ttm.tm_sec = SS;

    time_t ttime_t = mktime(&ttm);

    system_clock::time_point time_point_result = std::chrono::system_clock::from_time_t(ttime_t);

    time_point_result += std::chrono::milliseconds(fff);

AAPT2 Error solution.

If your Android studio has been updated.

Maybe, you would face an error in the studio like "AAPT 2 error: check the log for details"

This error will occur when you have done something wrong in your .xml file such as incorrect value, content not found, etc.

But, At that time you will not have the error specification there. Because the new version of Android Studio does not give you a specific error. It gives like AAPT2 error.

If you want to know where the actual error is then

Follow step.

1. Look at the panel which is at the right of your Android studio Check out the "Gradle" tab and click on it.
2. You will see the "app" option. Click on it.
3. In the app options you will see [Tasks -> build] click on it.
4. Then you will get options list and see "assembleDebug" double click on it.
5. Keep the patience and See build tab at the bottom panel of Android studios, you will get an exact error there what you made a mistake in which file and which position.

Try curl -v http://localhost:8080/ instead of 127.0.0.1

I have discovered that NotePad++ now also creates a subfolder at the file location, called nppBackup. So if your file lived in a folder called c:/thisfolder have a look to see if there's a folder called c:/thisfolder/nppBackup.

Occasionally I couldn't find the backup in AppData\Roaming\Notepad++\backup, but I found it in nppBackup.

Hi this works for Swift 4.

    override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    self.navigationController?.navigationBar.shadowImage = UIImage()
    self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: .default)
    self.navigationController?.navigationBar.isTranslucent = false
}

you need to put this in viewDidLayoutSubviews instead of viewDidLoad

\df+ <function_name> in psql.

You've got two ways to go forward:

JSONP

If this API supports JSONP, the easiest way to fix this issue is to add &callback to the end of the URL. You can also try &callback=. If that doesn't work, it means the API does not support JSONP, so you must try the other solution.

Proxy Script

You can create a proxy script on the same domain as your website in order to avoid the cross-origin issues. This will only work with HTTP URLs, not HTTPS URLs, but it shouldn't be too difficult to modify if you need that.

<?php
// File Name: proxy.php
if (!isset($_GET['url'])) {
    die(); // Don't do anything if we don't have a URL to work with
}
$url = urldecode($_GET['url']);
$url = 'http://' . str_replace('http://', '', $url); // Avoid accessing the file system
echo file_get_contents($url); // You should probably use cURL. The concept is the same though

Then you just call this script with jQuery. Be sure to urlencode the URL.

$.ajax({
    url      : 'proxy.php?url=http%3A%2F%2Fapi.master18.tiket.com%2Fsearch%2Fautocomplete%2Fhotel%3Fq%3Dmah%26token%3D90d2fad44172390b11527557e6250e50%26secretkey%3D83e2f0484edbd2ad6fc9888c1e30ea44%26output%3Djson',
    type     : 'GET',
    dataType : 'json'
}).done(function(data) {
    console.log(data.results.result[1].category); // Do whatever you want here
});

The Why

You're getting this error because of XMLHttpRequest same origin policy, which basically boils down to a restriction of ajax requests to URLs with a different port, domain or protocol. This restriction is in place to prevent cross-site scripting (XSS) attacks.

More Information

Our solutions by pass these problems in different ways.

JSONP uses the ability to point script tags at JSON (wrapped in a javascript function) in order to receive the JSON. The JSONP page is interpreted as javascript, and executed. The JSON is passed to your specified function.

The proxy script works by tricking the browser, as you're actually requesting a page on the same origin as your page. The actual cross-origin requests happen server-side.

As today, the best is probably to use Paris, a library provided by AirBnB.

Styles can then be applied like this:

Paris.style(myView).apply(R.style.MyStyle);

it also support custom view (if you extend a view) using annotations:

@Styleable and @Style

Thanks for the info, think I see the problem. This is a bug in hive-go that only shows up when you add a host. The last lines of it are:

app.listen(3001);
console.log("... port %d in %s mode", app.address().port, app.settings.env);

When you add the host on the first line, it is crashing when it calls app.address().port.

The problem is the potentially asynchronous nature of .listen(). Really it should be doing that console.log call inside a callback passed to listen. When you add the host, it tries to do a DNS lookup, which is async. So when that line tries to fetch the address, there isn't one yet because the DNS request is running, so it crashes.

Try this:

app.listen(3001, 'localhost', function() {
  console.log("... port %d in %s mode", app.address().port, app.settings.env);
});

Add -fPIC at the end of CMAKE_CXX_FLAGS and CMAKE_C_FLAG

Example:

set( CMAKE_CXX_FLAGS  "${CMAKE_CXX_FLAGS} -Wall --std=c++11 -O3 -fPIC" )
set( CMAKE_C_FLAGS  "${CMAKE_C_FLAGS} -Wall -O3 -fPIC" )

This solved my issue.

Solution for JUnit 5

The documentation says:

However, JUnit Jupiter’s org.junit.jupiter.Assertions class does not provide an assertThat() method like the one found in JUnit 4’s org.junit.Assert class which accepts a Hamcrest Matcher. Instead, developers are encouraged to use the built-in support for matchers provided by third-party assertion libraries.

Example for Hamcrest:

import static org.hamcrest.CoreMatchers.instanceOf;
import static org.hamcrest.MatcherAssert.assertThat;

import org.junit.jupiter.api.Test;

class HamcrestAssertionDemo {

    @Test
    void assertWithHamcrestMatcher() {
        SubClass subClass = new SubClass();
        assertThat(subClass, instanceOf(BaseClass.class));
    }

}

Example for AssertJ:

import static org.assertj.core.api.Assertions.assertThat;

import org.junit.jupiter.api.Test;

class AssertJDemo {

    @Test
    void assertWithAssertJ() {
        SubClass subClass = new SubClass();
        assertThat(subClass).isInstanceOf(BaseClass.class);
    }

}

Note that this assumes you want to test behaviors similar to instanceof (which accepts subclasses). If you want exact equal type, I don’t see a better way than asserting the two class to be equal like you mentioned in the question.

For money, always decimal. It's why it was created.

If numbers must add up correctly or balance, use decimal. This includes any financial storage or calculations, scores, or other numbers that people might do by hand.

If the exact value of numbers is not important, use double for speed. This includes graphics, physics or other physical sciences computations where there is already a "number of significant digits".

On Logout from the Client Side, the easiest way is to remove the token from the storage of browser.

But, What if you want to destroy the token on the Node server -

The problem with JWT package is that it doesn't provide any method or way to destroy the token.

So in order to destroy the token on the serverside you may use jwt-redis package instead of JWT

This library (jwt-redis) completely repeats the entire functionality of the library jsonwebtoken, with one important addition. Jwt-redis allows you to store the token label in redis to verify validity. The absence of a token label in redis makes the token not valid. To destroy the token in jwt-redis, there is a destroy method

it works in this way :

1) Install jwt-redis from npm

2) To Create -

var redis = require('redis');
var JWTR =  require('jwt-redis').default;
var redisClient = redis.createClient();
var jwtr = new JWTR(redisClient);

jwtr.sign(payload, secret)
    .then((token)=>{
            // your code
    })
    .catch((error)=>{
            // error handling
    });

3) To verify -

jwtr.verify(token, secret);

4) To Destroy -

jwtr.destroy(token)

Note : you can provide expiresIn during signin of token in the same as it is provided in JWT.

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

data[data$Ozone > 14, ]

Use filter (short version without doing a function with lambda, using __le__):

j2 = filter((5).__le__, j)

Example (python 3):

>>> j=[4,5,6,7,1,3,7,5]
>>> j2 = filter((5).__le__, j)
>>> j2
<filter object at 0x000000955D16DC18>
>>> list(j2)
[5, 6, 7, 7, 5]
>>> 

Example (python 2):

>>> j=[4,5,6,7,1,3,7,5]
>>> j2 = filter((5).__le__, j)
>>> j2
[5, 6, 7, 7, 5]
>>>

Use __le__ i recommend this, it's very easy, __le__ is your friend

If want to sort it to desired output (both versions):

>>> j=[4,5,6,7,1,3,7,5]
>>> j2 = filter((5).__le__, j)
>>> sorted(j2)
[5, 5, 6, 7, 7]
>>> 

Use sorted

Timings:

>>> from timeit import timeit
>>> timeit(lambda: [i for i in j if i >= 5]) # Michael Mrozek
1.4558496298222325
>>> timeit(lambda: filter(lambda x: x >= 5, j)) # Justin Ardini
0.693048732089828
>>> timeit(lambda: filter((5).__le__, j)) # Mine
0.714461565831428

For the current Python Launcher

If you have Py3 installed but default to py2

py -3 -m pip install ipykernel
py -3 -m ipykernel install --user

If you have Py2 installed but default to py3

py -2 -m pip install ipykernel
py -2 -m ipykernel install --user

I know it is maybe too late for this, but this could be usefull: If you try to know Apache Tomcat Server version from Java code, you can use:

from a HttpServlet:

protected void doGet(HttpServletRequest request, HttpServletResponse response) {
    getServletContext().getServerInfo()
}

from a ServletContextListener:

public void contextInitialized(ServletContextEvent event)  { 
    event.getServletContext().getServerInfo();      
}

From the context, the conflict was caused by the version of the package.
Let's take a look the manual about rpm:

--force
    Same as using --replacepkgs, --replacefiles, and --oldpackage.

--oldpackage
    Allow an upgrade to replace a newer package with an older one.

So, you can execute the command rpm -Uvh info-4.13a-2.rpm --force to solve your issue.

You can also use the tab character '\t' to represent a tab, instead of "\t".

char c ='t';
char c =(char)9;

It is also good to set the access security - just replace * with the domain you want to be able to reach it.

<?php
header('Access-Control-Allow-Origin: *');
header('Content-type: application/json');
    $response = array();
    $response[0] = array(
        'id' => '1',
        'value1'=> 'value1',
        'value2'=> 'value2'
    );

echo json_encode($response); 
?>

Here is more samples on that: how to bypass Access-Control-Allow-Origin?

Any color parse into int simplest two way here:

1) Get System Color

int redColorValue = Color.RED;

2) Any Color Hex Code as a String Argument

int greenColorValue = Color.parseColor("#00ff00")

MUST REMEMBER in above code Color class must be android.graphics...!

To check on elasticsearch cluster health you need to use

curl localhost:9200/_cat/health

More on the cat APIs here.

I usually use elasticsearch-head plugin to visualize that.

You can find it's github project here.

It's easy to install sudo $ES_HOME/bin/plugin -i mobz/elasticsearch-head and then you can open localhost:9200/_plugin/head/ in your web brower.

You should have something that looks like this :

There is no funtion like rownum, row_num() in MySQL but the way around is like below:

select 
      @s:=@s+1 serial_no, 
      tbl.* 
from my_table tbl, (select @s:=0) as s;

Don't use quotes with <<EOF:

var=$1
sudo tee "/path/to/outfile" > /dev/null <<EOF
Some text that contains my $var
EOF

Variable expansion is the default behavior inside of here-docs. You disable that behavior by quoting the label (with single or double quotes).

You can try these below views.

SELECT * FROM USER_SYS_PRIVS; 
SELECT * FROM USER_TAB_PRIVS;
SELECT * FROM USER_ROLE_PRIVS;

DBAs and other power users can find the privileges granted to other users with the DBA_ versions of these same views. They are covered in the documentation .

Those views only show the privileges granted directly to the user. Finding all the privileges, including those granted indirectly through roles, requires more complicated recursive SQL statements:

select * from dba_role_privs connect by prior granted_role = grantee start with grantee = '&USER' order by 1,2,3;
select * from dba_sys_privs  where grantee = '&USER' or grantee in (select granted_role from dba_role_privs connect by prior granted_role = grantee start with grantee = '&USER') order by 1,2,3;
select * from dba_tab_privs  where grantee = '&USER' or grantee in (select granted_role from dba_role_privs connect by prior granted_role = grantee start with grantee = '&USER') order by 1,2,3,4;

This should help you

Others have answered your question, but I'll go into a little bit more detail:

Python's is compares identity - it asks the question "is this one thing actually the same object as this other thing" (similar to == in Java). So, there are some times when using is makes sense - the most common one being checking for None. Eg, foo is None. But, in general, it isn't what you want.

==, on the other hand, asks the question "is this one thing logically equivalent to this other thing". For example:

>>> [1, 2, 3] == [1, 2, 3]
True
>>> [1, 2, 3] is [1, 2, 3]
False

And this is true because classes can define the method they use to test for equality:

>>> class AlwaysEqual(object):
...     def __eq__(self, other):
...         return True
...
>>> always_equal = AlwaysEqual()
>>> always_equal == 42
True
>>> always_equal == None
True

But they cannot define the method used for testing identity (ie, they can't override is).

I got the same error ("Uncaught SyntaxError: Unexpected token <" ) at these two lines when testing a sample application .

<script type = "text/javascript"  src="raphael-min.js"></script>
<script type = "text/javascript"  src="kuma-gauge.jquery.js"></script>

After a control, I realized that, local file locations are not correct and my local server app returns default page as the result. Client app can find the files but the founded files are default page, not the *.js files. So I receive Uncaught SyntaxError: Unexpected token <

I changed to orginal location on the intenet andit solved.

Setting the $PYTHONPATH environment variable does not seem to affect the Spyder IDE's iPython terminals on a Mac. However, Spyder's application menu contains a "PYTHONPATH manager." Adding my path here solved my problem. The "PYTHONPATH manager" is also persistent across application restarts.

This is specific to a Mac, because setting the PYTHONPATH environment variable on my Windows PC gives the expected behavior (modules are found) without using the PYTHONPATH manager in Spyder.

Here, i am using link in the form of button for CANCEL operation.

Try

var ts = TimeSpan.Parse(stringTime);

With a newer .NET you also have

TimeSpan ts;

if(!TimeSpan.TryParse(stringTime, out ts)){
     // throw exception or whatnot
}
// ts now has a valid format

This is the general idiom for parsing strings in .NET with the first version handling erroneous string by throwing FormatException and the latter letting the Boolean TryParse give you the information directly.

Auth::routes() is just a helper class that helps you generate all the routes required for user authentication. You can browse the code here https://github.com/laravel/framework/blob/5.3/src/Illuminate/Routing/Router.php instead.

Here are the routes

// Authentication Routes...
$this->get('login', 'Auth\LoginController@showLoginForm')->name('login');
$this->post('login', 'Auth\LoginController@login');
$this->post('logout', 'Auth\LoginController@logout')->name('logout');

// Registration Routes...
$this->get('register', 'Auth\RegisterController@showRegistrationForm')->name('register');
$this->post('register', 'Auth\RegisterController@register');

// Password Reset Routes...
$this->get('password/reset', 'Auth\ForgotPasswordController@showLinkRequestForm');
$this->post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail');
$this->get('password/reset/{token}', 'Auth\ResetPasswordController@showResetForm');
$this->post('password/reset', 'Auth\ResetPasswordController@reset');

Just run into the same problem and was the database returning the values as strings.

I use this as a workaround:

$a = array(
    'id' => $row['id'] * 1,
    'another' => ...,
    'ananother' => ...,
);
$json = json_encode($a);

That is multiplying the value by 1 to cast it into a number

Hope that helps someone

xsi:nil is the correct way to represent a value such that: When the DOM Level 2 call getElementValue() is issued, the NULL value is returned. xsi:nil is also used to indicate a valid element with no content even if that elements content type normally doesn't allow empty elements.

If an empty tag is used, getElementValue() returns the empty string ("") If the tag is omitted, then no author tag is even present. This may be semantically different than setting it to 'nil' (Ex. Setting "Series" to nil may be that the book belongs to no series, while omitting series could mean that series is an inapplicable element to the current element.)

From: The W3C

XML Schema: Structures introduces a mechanism for signaling that an element should be accepted as ·valid· when it has no content despite a content type which does not require or even necessarily allow empty content. An element may be ·valid· without content if it has the attribute xsi:nil with the value true. An element so labeled must be empty, but can carry attributes if permitted by the corresponding complex type.

A clarification:
If you have a book xml element and one of the child elements is book:series you have several options when filling it out:

1. Removing the element entirely - This can be done when you wish to indicate that series does not apply to this book or that book is not part of a series. In this case xsl transforms (or other event based processors) that have a template that matches book:series will never be called. For example, if your xsl turns the book element into table row (xhtml:tr) you may get the incorrect number of table cells (xhtml:td) using this method.
2. Leaving the element empty - This could indicate that the series is "", or is unknown, or that the book is not part of a series. Any xsl transform (or other evernt based parser) that matches book:series will be called. The value of current() will be "". You will get the same number of xhtml:td tags using this method as with the next described one.
3. Using xsi:nil="true" - This signifies that the book:series element is NULL, not just empty. Your xsl transform (or other event based parser) that have a template matching book:series will be called. The value of current() will be empty (not empty string). The main difference between this method and (2) is that the schema type of book:series does not need to allow the empty string ("") as a valid value. This makes no real sense for a series element, but for a language element that is defined as an enumerated type in the schema, xsi:nil="true" allows the element to have no data. Another example would be elements of type decimal. If you want them to be empty you can union an enumerated string that only allows "" and a decimal, or use a decimal that is nillable.

From the documentation about ASP.NET Web Project Folder Structure in MSDN:

You can keep your Web project's files in any folder structure that is convenient for your application. To make it easier to work with your application, ASP.NET reserves certain file and folder names that you can use for specific types of content.

App_Data contains application data files including .mdf database files, XML files, and other data store files. The App_Data folder is used by ASP.NET to store an application's local database, such as the database for maintaining membership and role information. For more information, see Introduction to Membership and Understanding Role Management.

Try this:

function getYesterdaysDate() {
    var date = new Date();
    date.setDate(date.getDate()-1);
    return date.getDate() + '/' + (date.getMonth()+1) + '/' + date.getFullYear();
}

I encountered similar problems in both chrome and firefox though it may not be the solution for your issue. Am sharing here in the hopes it may help others. I have encountered this situation before in other unrelated projects but never understood why until it cropped up again today.

Scenario:

I have one page that uses two bootstrap modals that come from the same source and one set of javascript files (blueimp's awesome jquery fileupload).

• BS Modal 1 is rendered on page load (via php) and is always present on the page. It is used for adding a new related record. (CakePHP....think SalesForcey type stuff)

• BS Modal 2 is used for editing existing related records and it's html content is pulled in from an ajax call and appended to the DOM via jQuery.

• Javascript supporting both modals included via standard html <script> tags.

I noticed that breakpoints are only triggered on Modal 1. They do not work when the code is being executed on the dynamically added Modal 2, even though it is quite obvious that the code is indeed being evaluated and run. Alert boxes pop up, codey type things get executed and output follows the logic set forth in the code.

I have not dived deeper to investigate further because I'm pressed for time, but wanted to put it out there and give back to the community.

PS: I use SO all the time, but this is my first post, so go easy on me :-)

I assume you're trying to tunnel into some unix box.

Make sure X11 forwarding is enabled in your PuTTY settings.

You can access sequence elements with arr.0 arr.1 and so on. See The Django template system chapter of the django book for more information.

top refers to the window object which contains all the current frames ( father of the rest of the windows ). window is the current window.

http://www.howtocreate.co.uk/tutorials/javascript/browserinspecific

so top.location.href can contain the "master" page link containing all the frames, while window.location.href just contains the "current" page link.

A certain type of rounding is also implemented in Boost:

#include <iostream>

#include <boost/numeric/conversion/converter.hpp>

template<typename T, typename S> T round2(const S& x) {
  typedef boost::numeric::conversion_traits<T, S> Traits;
  typedef boost::numeric::def_overflow_handler OverflowHandler;
  typedef boost::numeric::RoundEven<typename Traits::source_type> Rounder;
  typedef boost::numeric::converter<T, S, Traits, OverflowHandler, Rounder> Converter;
  return Converter::convert(x);
}

int main() {
  std::cout << round2<int, double>(0.1) << ' ' << round2<int, double>(-0.1) << ' ' << round2<int, double>(-0.9) << std::endl;
}

Note that this works only if you do a to-integer conversion.

This is strange but Logger.getLogger("global") does not work in my setup (as well as Logger.getLogger(Logger.GLOBAL_LOGGER_NAME)).

However Logger.getLogger("") does the job well.

Hope this info also helps somebody...

You can't use a foreach statement for that. The foreach is using internally an iterator:

The iterators returned by this class's iterator and listIterator methods are fail-fast: if the list is structurally modified at any time after the iterator is created, in any way except through the iterator's own remove or add methods, the iterator will throw a ConcurrentModificationException.

(From ArrayList javadoc)

In the foreach statement you don't have access to the iterator's add method and in any case that's still not the type of add that you want because it does not append at the end. You'll need to traverse the list manually:

int listSize = list.size();
for(int i = 0; i < listSize; ++i)
  list.add("whatever");

Note that this is only efficient for Lists that allow random access. You can check for this feature by checking whether the list implements the RandomAccess marker interface. An ArrayList has random access. A linked list does not.

Not exactly elegant, but the best (and quickest) solution i could find was using OnError. This will be significantly faster than iteration for any medium to large collection.

Public Function InCollection(col As Collection, key As String) As Boolean
  Dim var As Variant
  Dim errNumber As Long

  InCollection = False
  Set var = Nothing

  Err.Clear
  On Error Resume Next
    var = col.Item(key)
    errNumber = CLng(Err.Number)
  On Error GoTo 0

  '5 is not in, 0 and 438 represent incollection
  If errNumber = 5 Then ' it is 5 if not in collection
    InCollection = False
  Else
    InCollection = True
  End If

End Function

You can extend jQuery functionalities like this:

jQuery.fn.extend({
scrollToMe: function () {
    var x = jQuery(this).offset().top - 100;
    jQuery('html,body').animate({scrollTop: x}, 500);
}});

and then:

$('...').scrollToMe();

easy ;-)

Only using class names is not sufficient in your case.

• By.cssSelector(".ban") has 15 matching nodes
• By.cssSelector(".hot") has 11 matching nodes
• By.cssSelector(".ban.hot") has 5 matching nodes

Therefore you need more restrictions to narrow it down. Option 1 and 2 below are available for css selector, 1 might be the one that suits your needs best.

Option 1: Using list items' index (CssSelector or XPath)

Limitations

• Not stable enough if site's structure changes

Example:

driver.FindElement(By.CssSelector("#rightbar > .menu > li:nth-of-type(3) > h5"));
driver.FindElement(By.XPath("//*[@id='rightbar']/ul/li[3]/h5"));

Option 2: Using Selenium's FindElements, then index them. (CssSelector or XPath)

Limitations

• Not stable enough if site's structure changes
• Not the native selector's way

Example:

// note that By.CssSelector(".ban.hot") and //*[contains(@class, 'ban hot')] are different, but doesn't matter in your case
IList<IWebElement> hotBanners = driver.FindElements(By.CssSelector(".ban.hot"));
IWebElement banUsStates = hotBanners[3];

Option 3: Using text (XPath only)

Limitations

• Not for multilanguage sites
• Only for XPath, not for Selenium's CssSelector

Example:

driver.FindElement(By.XPath("//h5[contains(@class, 'ban hot') and text() = 'us states']"));

Option 4: Index the grouped selector (XPath only)

Limitations

• Not stable enough if site's structure changes
• Only for XPath, not CssSelector

Example:

driver.FindElement(By.XPath("(//h5[contains(@class, 'ban hot')])[3]"));

Option 5: Find the hidden list items link by href, then traverse back to h5 (XPath only)

Limitations

• Only for XPath, not CssSelector
• Low performance
• Tricky XPath

Example:

driver.FindElement(By.XPath(".//li[.//ul/li/a[contains(@href, 'geo.craigslist.org/iso/us/al')]]/h5"));

$('#select').val('defaultValue'); 
$('#select').change();

This will also trigger events hooked to this select

select replace(wm_concat(new),',','-') exp_res from (select distinct initcap(substr(name,decode(level,1,1,instr(name,'-',1,level-1)+1),decode(level,(length(name)-length(replace(name,'-','')))+1,9999,instr(name,'-',1,level)-1-decode(level,1,0,instr(name,'-',1,level-1))))) new from table;
connect by level<= (select (length(name)-length(replace(name,'-','')))+1 from table));

firstOrCreate() checks for all the arguments to be present before it finds a match. If not all arguments match, then a new instance of the model will be created.

If you only want to check on a specific field, then use firstOrCreate(['field_name' => 'value']) with only one item in the array. This will return the first item that matches, or create a new one if not matches are found.

The difference between firstOrCreate() and firstOrNew():

• firstOrCreate() will automatically create a new entry in the database if there is not match found. Otherwise it will give you the matched item.
• firstOrNew() will give you a new model instance to work with if not match was found, but will only be saved to the database when you explicitly do so (calling save() on the model). Otherwise it will give you the matched item.

Choosing between one or the other depends on what you want to do. If you want to modify the model instance before it is saved for the first time (e.g. setting a name or some mandatory field), you should use firstOrNew(). If you can just use the arguments to immediately create a new model instance in the database without modifying it, you can use firstOrCreate().

You are testing if the values of the variables error and Already are present in RepoOutput[RepoName.index(repo)]. If these variables don't exist then an undefined object is used.

Both of your if and elif tests therefore are false; there is no undefined object in the value of RepoOutput[RepoName.index(repo)].

I think you wanted to test if certain strings are in the value instead:

{% if "error" in RepoOutput[RepoName.index(repo)] %}
    <td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% elif "Already" in RepoOutput[RepoName.index(repo) %}
    <td id="good"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% else %}
    <td id="error"> {{ RepoOutput[RepoName.index(repo)] }} </td>
{% endif %}
</tr>

Other corrections I made:

• Used {% elif ... %} instead of {$ elif ... %}.
• moved the </tr> tag out of the if conditional structure, it needs to be there always.
• put quotes around the id attribute

Note that most likely you want to use a class attribute instead here, not an id, the latter must have a value that must be unique across your HTML document.

Personally, I'd set the class value here and reduce the duplication a little:

{% if "Already" in RepoOutput[RepoName.index(repo)] %}
    {% set row_class = "good" %}
{% else %}
    {% set row_class = "error" %}
{% endif %}
<td class="{{ row_class }}"> {{ RepoOutput[RepoName.index(repo)] }} </td>

a similar solution using jquery would be:

$(window).scroll(function () {
  $('.header').css('position','fixed');
});

This turns the header into a fixed position element immediately on scroll

Simple and Best way is whenever you open new file it is in preview mode so simply press the CTRL + K and then press ENTER then you done with preview mode , Now this file will remain always open until you closed it that's what you need to do ....

The problem mainly occurs after updating OS X to El Capitan (OS X 10.11) or macOS Sierra (macOS 10.12).

This is because of file permission issues with El Capitan’s or later macOS's new SIP process. Try changing the permissions for the /usr/local directory:

$ sudo chown -R $(whoami):admin /usr/local  

If it still doesn't work, use these steps inside a terminal session and everything will be fine:

cd /usr/local/Library/Homebrew  
git reset --hard  
git clean -df
brew update

This may be because homebrew is not updated.

Based on Adam Sills answer above - here's a nice clean extensions method for Contains... :)

///----------------------------------------------------------------------
/// <summary>
/// Determines whether the specified list contains the matching string value
/// </summary>
/// <param name="list">The list.</param>
/// <param name="value">The value to match.</param>
/// <param name="ignoreCase">if set to <c>true</c> the case is ignored.</param>
/// <returns>
///   <c>true</c> if the specified list contais the matching string; otherwise, <c>false</c>.
/// </returns>
///----------------------------------------------------------------------
public static bool Contains(this List<string> list, string value, bool ignoreCase = false)
{
    return ignoreCase ?
        list.Any(s => s.Equals(value, StringComparison.OrdinalIgnoreCase)) :
        list.Contains(value);
}

In some cases of which I can't remember why but $('#selectlist').val() won't always return the correct item value, so I use $('#selectlist option:selected').val() instead.

To check if LocalDb is installed or not:

• run cmd and type in sqllocaldb i this should give you the installed sqllocaldb instances if found.
• Run SSMS (SQL Server Management Studio).
• Try to connect to this instance (localdb)\V11.0 using windows authentication.

If an error is raised Cannot connect to (localdb)\V11.0. change the instance name to (localdb)\MSSQLLocalDB and try again to connect, if you still get the same error.

Follow these steps to install LocalDb:

• Close SSMS.
• Close VS (Visual Studio) if it's running.
• Go to Start Menu and type in search sqlLocalDb.
• From the results that appears choose sqlLocalDb.msi and click it.
• SQL setup will start to install LocalDB

after finishing the installation re-run SSMS and try connecting to either of the instances (localdb)\V11.0 or (localdb)\MSSQLLocalDB, one of it should work depending on what Visual Studio version you have.

You can also verify that localdb is installed using Visual Studio by simply creating new sql file and go to the connect icon on the top header of the file which by default lists all the servers you can connect to including localdb if installed.

In addition to the above mentioned ways of finding if localdb is installed, you can also use the MS windows power shell or windows command processor CMD or even NuGet package manager console on your server machine and run these commands sqllocaldb i and sqllocaldb v that will show you the localdb name if it is installed and the MSSQL server version installed and running on your machine.

This will format column A as text, B as General, C as a number.

Sub formatColumns()
 Columns(1).NumberFormat = "@"
 Columns(2).NumberFormat = "General"
 Columns(3).NumberFormat = "0"
End Sub

@WoooHaaaa some third party packages use 'django.middleware.csrf.CsrfViewMiddleware' middleware. for example i use django-rest-oauth and i have problem like you even after disabling those things. maybe these packages responded to your request like my case, because you use authentication decorator and something like this.

I thought a fully-functioning reCaptcha v3 example demo in PHP, using a Bootstrap 4 form, might be useful to some.

Reference the shown dependencies, swap in your email address and keys (create your own keys here), and the form is ready to test and use. I made code comments to better clarify the logic and also included commented-out console log and print_r lines to quickly enable viewing the validation token and data generated from Google.

The included jQuery function is optional, though it does create a much better user prompt experience in this demo.

Add secret key (2 places) and email address where noted.

      'content' => http_build_query($data)
    )
    );
  
  # Creates and returns stream context with options supplied in options preset

  }, 10000);
}

form.submit(function (e) {
  e.preventDefault();
  form_data = $(this).serialize();
  $.ajax({
    type: 'POST',
    url: form.attr('action'),
    data: form_data
  })
  .done(done_func)
  .fail(fail_func);
}); })(jQuery);

The __del__ method, it will be called when the object is garbage collected. Note that it isn't necessarily guaranteed to be called though. The following code by itself won't necessarily do it:

del obj

The reason being that del just decrements the reference count by one. If something else has a reference to the object, __del__ won't get called.

There are a few caveats to using __del__ though. Generally, they usually just aren't very useful. It sounds to me more like you want to use a close method or maybe a with statement.

See the python documentation on __del__ methods.

One other thing to note: __del__ methods can inhibit garbage collection if overused. In particular, a circular reference that has more than one object with a __del__ method won't get garbage collected. This is because the garbage collector doesn't know which one to call first. See the documentation on the gc module for more info.

If all your divs start with editDialog as you stated, then you can use the following selector:

$("div[id^='editDialog']")

Or you could use a class selector instead if it's easier for you

<div id="editDialog-0" class="editDialog">...</div>

$(".editDialog")

You can use multiple ordering on multiple condition,

ORDER BY 
     (CASE 
        WHEN @AlphabetBy = 2  THEN [Drug Name]
      END) ASC,
    CASE 
        WHEN @TopBy = 1  THEN [Rx Count]
        WHEN @TopBy = 2  THEN [Cost]
        WHEN @TopBy = 3  THEN [Revenue]
    END DESC 

Make sure to add @XmlSeeAlso tag with your specific classes used inside JaxbList. It is very important else it throws HttpMessageNotWritableException

Do:

0,30 * * * * your_command

Here's my function to address the problem:

public static String getConvertedTime(double time){

    double h,m,s,mil;

    mil = time % 1000;
    s = time/1000;
    m = s/60;
    h = m/60;
    s = s % 60;
    m = m % 60;
    h = h % 24;

    return ((int)h < 10 ? "0"+String.valueOf((int)h) : String.valueOf((int)h))+":"+((int)m < 10 ? "0"+String.valueOf((int)m) : String.valueOf((int)m))
            +":"+((int)s < 10 ? "0"+String.valueOf((int)s) : String.valueOf((int)s))
            +":"+((int)mil > 100 ? String.valueOf((int)mil) : (int)mil > 9 ? "0"+String.valueOf((int)mil) : "00"+String.valueOf((int)mil));
}

You can use insert to specify where you want to new column to be. In this case, I use 0 to place the new column at the left.

df.insert(0, 'Name', 'abc')

  Name        Date  Open  High  Low  Close
0  abc  01-01-2015   565   600  400    450

Short answer

$now = date_create()->format('Y-m-d H:i:s');

Read below for the long answer.

The mimicry of the MySQL NOW() function in PHP

Here is a list of ways in PHP that mimic the MySQL NOW() function.

// relative date
$now = date_create('now')->format('Y-m-d H:i:s'); // works in php 5.2 and higher  
$now = date_create()->format('Y-m-d H:i:s'); // also works in php 5.2
$now = new DateTime('now')->format('Y-m-d H:i:s'); // syntax error!!!
$now = (new DateTime('now'))->format('Y-m-d H:i:s'); // works in php 5.4 and higher   
$now = date('Y-m-d H:i:s'); // Slightly higher performance, but less usable for date/time manipulations

// From Unix timestamp
// Using date_create() with a Unix timestamp will give you a FALSE,  
// and if you try to invoke format() on a FALSE then you'll get a: 
//     Fatal error: Call to a member function format() on boolean 
// So if you work with Unix timestamps then you could use: date_create_from_format().
$unixTimeStamp = 1420070400; // 01/01/2015 00:00:00
$y2015 = date_create_from_format('U', $unixTimeStamp, timezone_open('Europe/Amsterdam'))->format('Y-m-d H:i:s');
$y2015 = date('Y-m-d H:i:s', $unixTimeStamp);

I think that date_create()->format('Y-m-d H:i:s') is the best way because this approach allows you to handle time/time-zone manipulations easier than date('Y-m-d H:i:s') and it works since php 5.2.

The MySQL function NOW() gives the dateTime value in this format: 'YYYY-MM-DD HH:MM:SS'. See here: https://dev.mysql.com/doc/refman/8.0/en/date-and-time-functions.html#function_now.

An interesting fact is that it's possible to get the datetime format by running this query: SHOW VARIABLES LIKE 'd%e_format', the result could be something like this:

Variable_name     Value     
date_format       %Y-%m-%d
datetime_format   %Y-%m-%d %H:%i:%s

The variables up here are read-only variables. So you can't change it.

I guess the MySQL NOW() function gets it's format from the datetime_format variable.

The advantages of date_create()->format() instead date() summary

The favorable facts of date_create('now')->format('Y-m-d H:i:s') over date('Y-m-d H:i:s') are:

• easier to handle time manipulations
• easier to handle timezones
• o.o.p.

The disadvantages of date_create()->format() instead date()

The function date() has a slightly better performance than date_create()->format(). See benchmark test below.

$start = time();
for ($i = 0; $i <= 5000000; $i++) {
    $a = date_create('now')->format('Y-m-d H:i:s');
}
$end = time();                  
$elapsedTimeA = $end - $start;

echo 'Case A, elapsed time in seconds: ' . $elapsedTimeA;
echo '<br>';

$start = time();
for ($i = 0; $i <= 5000000; $i++) {
    $b = date('Y-m-d H:i:s');
}
$end = time();                   
$elapsedTimeB = $end - $start;

echo 'Case B, elapsed time in seconds: ' . $elapsedTimeB;
echo '<br>';
// OUTPUT
Case A, elapsed time in seconds: 31
Case B, elapsed time in seconds: 14

The upper case shows that date() is faster. However, if we change the test scenario a bit, then outcome will be different. See below:

$start = time();
$dt = date_create('now');
for ($i = 0; $i <= 5000000; $i++) {
    $a = $dt->format('Y-m-d H:i:s');
}
$end = time();                  
$elapsedTimeA = $end - $start;

echo 'Case A, elapsed time in seconds: ' . $elapsedTimeA;
echo '<br>';

$start = time();
for ($i = 0; $i <= 5000000; $i++) {
    $b = date('Y-m-d H:i:s');
}
$end = time();                   
$elapsedTimeB = $end - $start;

echo 'Case B, elapsed time in seconds: ' . $elapsedTimeB;
echo '<br>';
// OUTPUT
Case A, elapsed time in seconds: 14
Case B, elapsed time in seconds: 15

The DateTime method: format() is faster here than date().

The advantages of date_create()->format() instead date() detailed

Read on for the detailed explanation.

easier to handle time manipulations

date_create() accepts a relative date/time format (like now, yesterday or +1 day) see this link, example:

$tomorrow = date_create('+1 day')->format('Y-m-d H:i:s'); 

date() accepts a relative date/time format as well, like this:

$tomorrow = date('Y-m-d H:i:s', strtotime('+1 day'));
$tomorrow = date('Y-m-d H:i:s', (time() + 86400)); // 86400 seconds = 1 day

easier to handle timezones

When timezones matter then the usage of date_create()->format() makes a lot more sense then date() because date() uses the default time zone which is configured in php.ini at the date.timezone directive. Link: http://php.net/manual/en/datetime.configuration.php#ini.date.timezone .

It is possible to change the timezone during run-time. Example:

date_default_timezone_set('Asia/Tokyo');.

The downside of that is that it will affect all date/time functions. This problem doesn't exists if you are using date_create()->format() in combination with timezone_open().

PHP supports major timezones. The funny thing is that it even supports the Arctic circle, and Antarctica. Have you ever heard about Longyearbyen? If not, then don't worry, neither did I until I read the official PHP documentation.

$nowLongyearbyen = date_create('now', timezone_open('Arctic/Longyearbyen'))->format('Y-m-d H:i:s');

See a list of all supported timezones: http://php.net/manual/en/timezones.php.

o.o.p.

O.O.P. uses state-full Objects. So I prefer to think in this way:

// Create a DateTime Object. 
// Use the DateTime that applies for tomorrow.
// Give me the datetime in format 'Y-m-d H:i:s'
$tomorrow = date_create('+1 day')->format('Y-m-d H:i:s'); 

Then to think in this way:

// Give me a date time string in format 'Y-m-d H:i:s', 
// use strtotime() to calculate the Unix timestamp that applies for tomorrow.
$tomorrow = date('Y-m-d H:i:s', strtotime('+1 day'));

Therefore I would say that the date_create()->format() approach is more readable to me then date().

date_create() VS new DateTime()

The favorable facts of date_create() over new DateTime() are:

• Namespaces

Namespaces

If you work in a namespace and want to initialise a DateTime object with the new keyword, then you have to do it like this:

namespace my_namespace;

// The backslash must be used if you are in a namespace.
// Forgetting about the backslash results in a fatal error.
$dt = new \DateTime();

There is nothing wrong with this, but the downside of the above is that people forget sporadically about the backslash. By using the date_create() constructor function you don't have to worry about namespaces.

$dt = date_create(); // in or not in a namespace it works in both situations

Example of date_create()->format()

I use this approach for my projects if I have to fill an array. Like this:

$array = array(
    'name' => 'John',
    'date_time' => date_create('now')->format('Y-m-d H:i:s'), // uses the default timezone
    'date_time_japan' => date_create('now', timezone_open('Asia/Tokyo'))->format('Y-m-d H:i:s'),
);

In my case, where the timezones are not available on the server, this works great:

SELECT CONVERT_TZ(`date_field`,'+00:00',@@global.time_zone) FROM `table`

Note: global.time_zone uses the server timezone. You have to make sure, that it has the desired timezone!

Try this:

http://jsfiddle.net/qk2Pc/

var my_condition = true;
var lastSel = $("#my_select option:selected");

$("#my_select").change(function(){
  if(my_condition)
  {
    lastSel.prop("selected", true);
  }
});

$("#my_select").click(function(){
    lastSel = $("#my_select option:selected");
});

On linux command line, you can simply execute:

curl -H "Content-Type: text/xml; charset=utf-8" -H "SOAPAction:"  -d @your_soap_request.xml -X POST https://ws.paymentech.net/PaymentechGateway

For more generic advice on debugging this kind of problem MDN have a good article TypeError: "x" is not a function:

It was attempted to call a value like a function, but the value is not actually a function. Some code expects you to provide a function, but that didn't happen.

Maybe there is a typo in the function name? Maybe the object you are calling the method on does not have this function? For example, JavaScript objects have no map function, but JavaScript Array object do.

Basically the object (all functions in js are also objects) does not exist where you think it does. This could be for numerous reasons including(not an extensive list):

• Missing script library
• Typo
• The function is within a scope that you currently do not have access to, e.g.:

var x = function(){_x000D_
   var y = function() {_x000D_
      alert('fired y');_x000D_
   }_x000D_
};_x000D_
    _x000D_
//the global scope can't access y because it is closed over in x and not exposed_x000D_
//y is not a function err triggered_x000D_
x.y();

• Your object/function does not have the function your calling:

var x = function(){_x000D_
   var y = function() {_x000D_
      alert('fired y');_x000D_
   }_x000D_
};_x000D_
    _x000D_
//z is not a function error (as above) triggered_x000D_
x.z();

I think it is best way for you.

You should add this: this.onTodoChange = this.onTodoChange.bind(this).

And your function has event param(e), and get value:

componentWillMount(){
        this.setState({
            updatable : false,
            name : this.props.name,
            status : this.props.status
        });
    this.onTodoChange = this.onTodoChange.bind(this)
    }
    
    
<input className="form-control" type="text" value={this.state.name} id={'todoName' + this.props.id} onChange={this.onTodoChange}/>

onTodoChange(e){
         const {name, value} = e.target;
        this.setState({[name]: value});
   
}

String upToNCharacters = String.format("%."+ n +"s", str);

Awful if n is a variable (so you must construct the format string), but pretty clear if a constant:

String upToNCharacters = String.format("%.10s", str);

docs

    String a = "Some String";
    int count = 0;
    for (int i = 0; i < a.length(); i++) {

        if (Character.isWhitespace(a.charAt(i))) {
            count++; 
        }
    }
    System.out.println(count+1);

It will count white spaces. However, If we add 1 in count , we can get exact words.

There are couple of good free service that let you do the same. Ideal for showing something quickly for testing:

• http://localtunnel.me/
• https://ngrok.com/
• http://localhost.run/

Edits:

• add ngrok service
• add localhost.run service

JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.

var textBox = document.getElementById("myTextBox");
var textLength = textBox.value.length;
if(textLength > 5)
{
    //red
    textBox.style.backgroundColor = "#FF0000";
}
else
{
    //green
    textBox.style.backgroundColor = "#00FF00";
}

$location.search() will work only with HTML5 mode turned on and only on supporting browser.

This will work always:

$window.location.search

One more way -

select * from <table> where  id=(select max(id) from <table>)

Hi, try this solution. Simple use php array map

function myfunction($value)
{
 return strtolower($value);
}

$new_array = ["Value1","Value2","Value3" ];
print_r(array_map("myfunction",$new_array ));

Output Array ( [0] => value1 [1] => value2 [2] => value3 )

The direct replacement is if/elif/else.

However, in many cases there are better ways to do it in Python. See "Replacements for switch statement in Python?".

Here is my layout:

    <HorizontalScrollView
        android:id="@+id/horizontalScrollView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingTop="@dimen/padding" >

       <LinearLayout
        android:id="@+id/shapeLayout"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp" >
        </LinearLayout>
    </HorizontalScrollView>

And I populate it in the code with dynamic check-boxes.

I'm not sure why you'd want to validate an optional email address, but I'd suggest you use

^$|^[^@\s]+@[^@\s]+$

meaning

^$        empty string
|         or
^         beginning of string
[^@\s]+   any character but @ or whitespace
@         
[^@\s]+
$         end of string

You won't stop fake emails anyway, and this way you won't stop valid addresses.

The approach is to use geometry with animations applied. Add the required geometry to the Path and animate its RotateTransform from 0-360°.

My spinner support two types of spinners:

1. Circles :
2. Rings :

And the central logic looks like:

if(spinner.SpinnerType == SpinnerType.Ring)
{
 double innerRad = spinner.Radius - spinner.ItemRadius;
 Point center = new Point(0, 0);
 grp.Children.Add(new EllipseGeometry( center, spinner.Radius, spinner.Radius));
 grp.Children.Add(new EllipseGeometry(center, innerRad, innerRad));                
 return;
}
var points = GetPointsOnCircle( spinner.Diameter/ 2);
double r = spinner.ItemRadius;
foreach (var point in points)
{
 grp.Children.Add(new EllipseGeometry(point, r, r));
 r -= spinner.ContinuousSizeReduction;
}

Usage is as simple as follows:

<local:SpinnerControl Diameter="60" Fill="#FFE8B311"/>

Here is the source code!

padding: 0px solves the horizontal centering

whereas,

setting line-height equal to or less than the height of the button solves the vertical alignment.

The content of the Manifest file in a JAR file created with version 1.0 of the Java Development Kit is the following.

Manifest-Version: 1.0

All the entries are as name-value pairs. The name of a header is separated from its value by a colon. The default manifest shows that it conforms to version 1.0 of the manifest specification. The manifest can also contain information about the other files that are packaged in the archive. Exactly what file information is recorded in the manifest will depend on the intended use for the JAR file. The default manifest file makes no assumptions about what information it should record about other files, so its single line contains data only about itself. Special-Purpose Manifest Headers

Depending on the intended role of the JAR file, the default manifest may have to be modified. If the JAR file is created only for the purpose of archival, then the MANIFEST.MF file is of no purpose. Most uses of JAR files go beyond simple archiving and compression and require special information to be in the manifest file. Summarized below are brief descriptions of the headers that are required for some special-purpose JAR-file functions

Applications Bundled as JAR Files: If an application is bundled in a JAR file, the Java Virtual Machine needs to be told what the entry point to the application is. An entry point is any class with a public static void main(String[] args) method. This information is provided in the Main-Class header, which has the general form:

Main-Class: classname

The value classname is to be replaced with the application's entry point.

Download Extensions: Download extensions are JAR files that are referenced by the manifest files of other JAR files. In a typical situation, an applet will be bundled in a JAR file whose manifest references a JAR file (or several JAR files) that will serve as an extension for the purposes of that applet. Extensions may reference each other in the same way. Download extensions are specified in the Class-Path header field in the manifest file of an applet, application, or another extension. A Class-Path header might look like this, for example:

Class-Path: servlet.jar infobus.jar acme/beans.jar

With this header, the classes in the files servlet.jar, infobus.jar, and acme/beans.jar will serve as extensions for purposes of the applet or application. The URLs in the Class-Path header are given relative to the URL of the JAR file of the applet or application.

Package Sealing: A package within a JAR file can be optionally sealed, which means that all classes defined in that package must be archived in the same JAR file. A package might be sealed to ensure version consistency among the classes in your software or as a security measure. To seal a package, a Name header needs to be added for the package, followed by a Sealed header, similar to this:

Name: myCompany/myPackage/
Sealed: true

The Name header's value is the package's relative pathname. Note that it ends with a '/' to distinguish it from a filename. Any headers following a Name header, without any intervening blank lines, apply to the file or package specified in the Name header. In the above example, because the Sealed header occurs after the Name: myCompany/myPackage header, with no blank lines between, the Sealed header will be interpreted as applying (only) to the package myCompany/myPackage.

Package Versioning: The Package Versioning specification defines several manifest headers to hold versioning information. One set of such headers can be assigned to each package. The versioning headers should appear directly beneath the Name header for the package. This example shows all the versioning headers:

Name: java/util/
Specification-Title: "Java Utility Classes" 
Specification-Version: "1.2"
Specification-Vendor: "Sun Microsystems, Inc.".
Implementation-Title: "java.util" 
Implementation-Version: "build57"
Implementation-Vendor: "Sun Microsystems, Inc."

This originally answered a supplemental question about the wisdom of downloading jQuery versus accessing it via a CDN, which is no longer present...

To answer the thing about Google. I have moved over to accessing JQuery and most other of these sorts of libraries via the corresponding CDN in my sites.

As more people do this means that it's more likely to be cached on user's machines, so my vote goes for good idea.

In the five years since I first offered this, it has become common wisdom.

You don't need ROOT permissions to get the list of Installed Apps.

You can do it with android PackageManager.

Below is a small code snippet.

final PackageManager pm = getPackageManager();
//get a list of installed apps.
List<ApplicationInfo> packages =  pm.getInstalledApplications(PackageManager.GET_META_DATA);

for (ApplicationInfo packageInfo : packages) {
    Log.d(TAG, "Installed package :" + packageInfo.packageName);
    Log.d(TAG, "Apk file path:" + packageInfo.sourceDir);
}

Absence of Submit field element in the form also causes this error. In the case of "button" field handled by JS to submit form lacks the necessity of Submit button hence Required doesn't Work

Deletes all child fields in the database then we use on_delete as so:

class user(models.Model):
 commodities = models.ForeignKey(commodity, on_delete=models.CASCADE)

All of the snippets on this page can be dramatically reduced in size.

The mysqli result set object can be immediately fed to a foreach() (because it is "iterable") which eliminates the need to maked iterated _fetch() calls.

Imploding each row will allow your code to correctly print all columnar data in the result set without modifying the code.

$sql = "SELECT * FROM MY_TABLE";
echo '<table>';
    foreach (mysqli_query($conn, $sql) as $row) {
        echo '<tr><td>' . implode('</td><td>', $row) . '</td></tr>';
    }
echo '</table>';

If you want to encode html entities, you can map each row:

implode('</td><td>' . array_map('htmlspecialchars', $row))

If you don't want to use implode, you can simply access all row data using associative array syntax. ($row['id'])

Only 2 step , and you can use it everywhere in your application.

Step1. create a singleton to manager [avoiding multiple click]

package com.im.av.mediator;

import android.os.SystemClock;

import java.util.HashMap;

/**
 * Created by ShuHeng on 16/6/1.
 */
public class ClickManager {



    private HashMap<Integer,Long> laskClickTimeMap=new HashMap<Integer,Long>();
    public volatile static ClickManager mInstance =null;

    public static ClickManager getInstance(){
        if (mInstance == null) {
            synchronized(ClickManager.class) {
                if (mInstance == null) {
                    mInstance = new ClickManager();
                }
            }
        }
        return mInstance;
    }
   public boolean isClickable1s(Integer key){
       Long keyLong = laskClickTimeMap.get(key);
       if(keyLong==null){
           laskClickTimeMap.put(key,SystemClock.elapsedRealtime());
           return true;
       }else{
           if (SystemClock.elapsedRealtime() - keyLong.longValue() < 1000){
               return false;
           }else{
               laskClickTimeMap.put(key,new Long(SystemClock.elapsedRealtime()));
               return true;
           }
       }
   }
}  

Step2. add one line to avoid multiple click.

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    int id = v.getId();
    if (id == R.id.iv_back) {
        if(!ClickManager.getInstance().isClickable1s(R.id.iv_back))return;
        //do something
    } else if (id == R.id.iv_light) {
        if(!ClickManager.getInstance().isClickable1s(R.id.iv_light))return;
        //do something
    } else if (id == R.id.iv_camerarotate) {
        if(!ClickManager.getInstance().isClickable1s(R.id.iv_camerarotate))return;
           //do something
    } else if (id == R.id.btn_delete_last_clip) {
        if(!ClickManager.getInstance().isClickable1s(R.id.btn_delete_last_clip))return;
          //do something

    } else if (id == R.id.iv_ok) {
        if(!ClickManager.getInstance().isClickable1s(R.id.iv_ok))return;
        //do something
    }
}

Using a great similar service

private string GetPublicIpAddress()
{
    var request = (HttpWebRequest)WebRequest.Create("http://ifconfig.me");

    request.UserAgent = "curl"; // this will tell the server to return the information as if the request was made by the linux "curl" command

    string publicIPAddress;

    request.Method = "GET";
    using (WebResponse response = request.GetResponse())

No need for jQuery

JavaScript does have a native .trim() method.

var name = "    John Smith  ";
name = name.trim();

console.log(name); // "John Smith"

Example Here

String.prototype.trim()

The trim() method removes whitespace from both ends of a string. Whitespace in this context is all the whitespace characters (space, tab, no-break space, etc.) and all the line terminator characters (LF, CR, etc.).

Dirk Eddelbuettel's answer is the best; here I just note that you can get away with not pre-specifying the dataframe dimensions or data types, which is sometimes useful if you have multiple data types and lots of columns:

row1<-list("a",1,FALSE) #use 'list', not 'c' or 'cbind'!
row2<-list("b",2,TRUE)  

df<-data.frame(row1,stringsAsFactors = F) #first row
df<-rbind(df,row2) #now this works as you'd expect.

Step 1. On your desktop right click "New"->"Text Document" with name OpenGitBash.reg

Step 2. Right click the file and choose "Edit"

Step 3. Copy-paste the code below, save and close the file

Step 4. Execute the file by double clicking it

Note: You need administrator permission to write to the registry.

Windows Registry Editor Version 5.00
; Open files
; Default Git-Bash Location C:\Program Files\Git\git-bash.exe

[HKEY_CLASSES_ROOT\*\shell\Open Git Bash]
@="Open Git Bash"
"Icon"="C:\\Program Files\\Git\\git-bash.exe"

[HKEY_CLASSES_ROOT\*\shell\Open Git Bash\command]
@="\"C:\\Program Files\\Git\\git-bash.exe\" \"--cd=%1\""

; This will make it appear when you right click ON a folder
; The "Icon" line can be removed if you don't want the icon to appear

[HKEY_CLASSES_ROOT\Directory\shell\bash]
@="Open Git Bash"
"Icon"="C:\\Program Files\\Git\\git-bash.exe"


[HKEY_CLASSES_ROOT\Directory\shell\bash\command]
@="\"C:\\Program Files\\Git\\git-bash.exe\" \"--cd=%1\""

; This will make it appear when you right click INSIDE a folder
; The "Icon" line can be removed if you don't want the icon to appear

[HKEY_CLASSES_ROOT\Directory\Background\shell\bash]
@="Open Git Bash"
"Icon"="C:\\Program Files\\Git\\git-bash.exe"

[HKEY_CLASSES_ROOT\Directory\Background\shell\bash\command]
@="\"C:\\Program Files\\Git\\git-bash.exe\" \"--cd=%v.\""

And here is your result :

svn revert will undo any local changes you've made

expects X(feature matrix)

Try to put your features in a tuple like this:

features = ['TV', 'Radio', 'Newspaper']
X = data[features]

Or you can use GSON [https://code.google.com/p/google-gson/], where these null fields will be automatically removed.

SampleDTO.java

public class SampleDTO {

    String username;
    String email;
    String password;
    String birthday;
    String coinsPackage;
    String coins;
    String transactionId;
    boolean isLoggedIn;

    // getters/setters
}

Test.java

import com.google.gson.Gson;

public class Test {

    public static void main(String[] args) {
        SampleDTO objSampleDTO = new SampleDTO();
        Gson objGson = new Gson();
        System.out.println(objGson.toJson(objSampleDTO));
    }
}

OUTPUT:

{"isLoggedIn":false}

I used gson-2.2.4

even you can compile your c++ code by gcc Sounds funny ?? Yes it is. try it

$  gcc avishay.cpp -lstdc++

enjoy

According to Listening For and Broadcasting Global Messages, and Setting Alarms in Common Tasks and How to Do Them in Android:

If the receiving class is not registered using in its manifest, you can dynamically instantiate and register a receiver by calling Context.registerReceiver().

Take a look at registerReceiver (BroadcastReceiver receiver, IntentFilter filter) for more info.
