I did notice something of interest here: In my 2.3.4 phone I can't see AP/AdHoc SSIDs in the Settings > Wireless & Networks menu. On an Acer A500 running 4.0.3 I do see them, prefixed by (*)

However in the following bit of code that I adapted from (can't remember source, sorry!) I do see the Ad Hoc show up in the Wifi Scan on my 2.3.4 phone. I am still looking to actually connect and create a socket + input/outputStream. But, here ya go:

    public class MainActivity extends Activity {

private static final String CHIPKIT_BSSID = "E2:14:9F:18:40:1C";
private static final int CHIPKIT_WIFI_PRIORITY = 1;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    final Button btnDoSomething = (Button) findViewById(R.id.btnDoSomething);
    final Button btnNewScan = (Button) findViewById(R.id.btnNewScan);
    final TextView textWifiManager = (TextView) findViewById(R.id.WifiManager);
    final TextView textWifiInfo = (TextView) findViewById(R.id.WifiInfo);
    final TextView textIp = (TextView) findViewById(R.id.Ip);

    final WifiManager myWifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
    final WifiInfo myWifiInfo = myWifiManager.getConnectionInfo();

    WifiConfiguration wifiConfiguration = new WifiConfiguration();
    wifiConfiguration.BSSID = CHIPKIT_BSSID;
    wifiConfiguration.priority = CHIPKIT_WIFI_PRIORITY;
    wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
    wifiConfiguration.allowedKeyManagement.set(KeyMgmt.NONE);
    wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
    wifiConfiguration.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
    wifiConfiguration.status = WifiConfiguration.Status.ENABLED;

    myWifiManager.setWifiEnabled(true);

    int netID = myWifiManager.addNetwork(wifiConfiguration);

    myWifiManager.enableNetwork(netID, true);

    textWifiInfo.setText("SSID: " + myWifiInfo.getSSID() + '\n' 
            + myWifiManager.getWifiState() + "\n\n");

    btnDoSomething.setOnClickListener(new View.OnClickListener() {          
        public void onClick(View v) {
            clearTextViews(textWifiManager, textIp);                
        }           
    });

    btnNewScan.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            getNewScan(myWifiManager, textWifiManager, textIp);
        }
    });     
}

private void clearTextViews(TextView...tv) {
    for(int i = 0; i<tv.length; i++){
        tv[i].setText("");
    }       
}

public void getNewScan(WifiManager wm, TextView...textViews) {
    wm.startScan();

    List<ScanResult> scanResult = wm.getScanResults();

    String scan = "";

    for (int i = 0; i < scanResult.size(); i++) {
        scan += (scanResult.get(i).toString() + "\n\n");
    }

    textViews[0].setText(scan);
    textViews[1].setText(wm.toString());
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

Don't forget that in Eclipse you can use Ctrl+Shift+[letter O] to fill in the missing imports...

and my manifest:

    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.digilent.simpleclient"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main" >

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

Hope that helps!

Almost 2hrs on this issue! And finally I solved it by replacing the

iPhone Developer

to

iPhone Developer: My Dev Account Name

for Debug's CODE_SIGN_IDENTITY:

1. Select Project Target
2. Build Settings
3. Search by "code sign"
4. Modify CODE_SIGN_IDENTITY section's Debug row with "iPhone Developer: My Dev Account Name", not just "iPhone Developer".

I've no idea why it works, but it does! At least for me!

Environment: Xcode 5.0 (5A1412).

John's answer is 99% correct. I found that (at least in my configuration), you have to open the Build settings inspector for the PROJECT. The build settings for the target do not contain "Code Signing Entitlements". Perhaps this doesn't make a difference if you have only one target in your project. But if you have multiple targets, you need to go to the project build settings. In any case, after doing what John said, my ad-hoc distribution build worked perfectly.

It might work to use JmDNS on Android: http://jmdns.sourceforge.net/

There are tons of zeroconf-enabled machines out there, so this would enable discovery with more than just Android devices.

Your hack of decrementing the count at the end is exactly that -- a hack.

Far better to write your loop correctly in the first place, so it doesn't count the last line twice.

int main() { 
    int number_of_lines = 0;
    std::string line;
    std::ifstream myfile("textexample.txt");

    while (std::getline(myfile, line))
        ++number_of_lines;
    std::cout << "Number of lines in text file: " << number_of_lines;
    return 0;
}

Personally, I think in this case, C-style code is perfectly acceptable:

int main() {
    unsigned int number_of_lines = 0;
    FILE *infile = fopen("textexample.txt", "r");
    int ch;

    while (EOF != (ch=getc(infile)))
        if ('\n' == ch)
            ++number_of_lines;
    printf("%u\n", number_of_lines);
    return 0;
}

Edit: Of course, C++ will also let you do something a bit similar:

int main() {
    std::ifstream myfile("textexample.txt");

    // new lines will be skipped unless we stop it from happening:    
    myfile.unsetf(std::ios_base::skipws);

    // count the newlines with an algorithm specialized for counting:
    unsigned line_count = std::count(
        std::istream_iterator<char>(myfile),
        std::istream_iterator<char>(), 
        '\n');

    std::cout << "Lines: " << line_count << "\n";
    return 0;
}

Here's a Swift version:

func durationsBySecond(seconds s: Int) -> (days:Int,hours:Int,minutes:Int,seconds:Int) {
    return (s / (24 * 3600),(s % (24 * 3600)) / 3600, s % 3600 / 60, s % 60)
}

Can be used like this:

let (d,h,m,s) = durationsBySecond(seconds: duration)
println("time left: \(d) days \(h) hours \(m) minutes \(s) seconds")

I think you were pretty close, try this:

@{bool isUserConnected = string.IsNullOrEmpty(Model.CreatorFullName);}
@if (isUserConnected)
{ // meaning that the viewing user has not been saved so continue
    <div>
        <div> click to join us </div>
        <a id="login" href="javascript:void(0);" style="display: inline; ">join here</a>
    </div>
}

I use eclipse STS, so the maven plugin comes pre-installed. However, if you aren't using STS (Springsource Tool Suite), you can still install the m2Eclipse plugin. Here is the link:

http://www.eclipse.org/m2e/

Once you have this installed, you should be able to run all the maven commands. To do so, from the package explorer, you would right click on either the maven project or the pom.xml in the maven project, highlight Run As, then click Maven Install.

Hope this helped.

I've found that replacing the first part of the URL with IP address numbers instead of words worked for me.

For example use:

http://111.11.11.111/svn/Directory

instead of:

http://www.url.com/svn/Directory

A CSS selector approach could definitely work here. Try:

driver.findElement(By.CssSelector("a.item")).Click();

This will not work if there are other anchors before this one of the class item. You can better specify the exact element if you do something like "#my_table > a.item" where my_table is the id of a table that the anchor is a child of.

The following will order your data depending on both column in descending order.

ORDER BY article_rating DESC, article_time DESC

Using exit directly may be tricky as the script may be sourced from other places (e.g. from terminal). I prefer instead using subshell with set -e (plus errors should go into cerr, not cout) :

set -e
ERRCODE=0
my_command || ERRCODE=$?
test $ERRCODE == 0 ||
    (>&2 echo "My command failed ($ERRCODE)"; exit $ERRCODE)

You can insert new data into table by two ways.

1. Load the data of a file into table using load command.

   LOAD DATA [LOCAL] INPATH 'filepath' [OVERWRITE] INTO TABLE tablename.
   

2. You can insert new data into table by using select query.

   INSERT INTO table tablename1 select columnlist FROM secondtable;
   

tick_params is very useful for setting tick properties. Labels can be moved to the top with:

    ax.tick_params(labelbottom=False,labeltop=True)

In my Visual Studio 2019 it worked only after I set the AutoSizeColumnsMode property to None.

The following is needed:

• MS Online Services Assistant needs to be downloaded and installed.
• MS Online Module for PowerShell needs to be downloaded and installed
• Connect to Microsoft Online in PowerShell

Every second line has a trailing space :( After removing all trailing spaces it worked!

thank you

Use :

getline(cin, input);

the function can be found in

#include <string>

System.out.println(LocalDate.now().format(DateTimeFormatter.ofPattern("dd.MMMM yyyy")));

The above answer shows it for today

Yet another attempt: https://code.google.com/p/android-python27/

This one embed directly the Python interpretter in your app apk.

Although getattr() is elegant (and about 7x faster) method, you can get return value from the function (local, class method, module) with eval as elegant as x = eval('foo.bar')(). And when you implement some error handling then quite securely (the same principle can be used for getattr). Example with module import and class:

# import module, call module function, pass parameters and print retured value with eval():
import random
bar = 'random.randint'
randint = eval(bar)(0,100)
print(randint) # will print random int from <0;100)

# also class method returning (or not) value(s) can be used with eval: 
class Say:
    def say(something='nothing'):
        return something

bar = 'Say.say'
print(eval(bar)('nice to meet you too')) # will print 'nice to meet you' 

When module or class does not exist (typo or anything better) then NameError is raised. When function does not exist, then AttributeError is raised. This can be used to handle errors:

# try/except block can be used to catch both errors
try:
    eval('Say.talk')() # raises AttributeError because function does not exist
    eval('Says.say')() # raises NameError because the class does not exist
    # or the same with getattr:
    getattr(Say, 'talk')() # raises AttributeError
    getattr(Says, 'say')() # raises NameError
except AttributeError:
    # do domething or just...
    print('Function does not exist')
except NameError:
    # do domething or just...
    print('Module does not exist')

Note: you should use the accepted answer if possible. It's better than mine.

It's quite easy with the GD library.

It's built in usually, you probably have it (use phpinfo() to check)

$image = imagecreatefromjpeg("http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com");

imagejpeg($image, "folder/file.jpg");

The above answer is better (faster) for most situations, but with GD you can also modify it in some form (cropping for example).

$image = imagecreatefromjpeg("http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com");
imagecopy($image, $image, 0, 140, 0, 0, imagesx($image), imagesy($image));
imagejpeg($image, "folder/file.jpg");

This only works if allow_url_fopen is true (it is by default)

There are two syntax errors in your ternary conditional:

1. remove the keyword if. Check the correct syntax here.

2. You are missing a parenthesis in your code. If you format it like this:

   {(this.props.schema.collectionName.length < 0 ? 
      (<Expandable></Expandable>) 
      : (<h1>hejsan</h1>) 
   )}
   

Hope this works!

The compiler only knows that the type of "a" is Animal; this happens at compile time, because of which it is called static binding (Method overloading). But if it is dynamic binding then it would call the Dog class method. Here is an example of dynamic binding.

public class DynamicBindingTest {

    public static void main(String args[]) {
        Animal a= new Dog(); //here Type is Animal but object will be Dog
        a.eat();       //Dog's eat called because eat() is overridden method
    }
}

class Animal {

    public void eat() {
        System.out.println("Inside eat method of Animal");
    }
}

class Dog extends Animal {

    @Override
    public void eat() {
        System.out.println("Inside eat method of Dog");
    }
}

Output: Inside eat method of Dog

Yes, I also found it here: http://developer.android.com/tools/testing/activity_testing.html It's seems a key-input protection mechanism which includes the screen-lock, but not only includes it. According to this webpage, it also defines some key-input restriction for auto-test framework in Android.

Inserting data into a pandas dataframe and providing column name.

import pandas as pd
df = pd.DataFrame([['A','C','A','B','C','A','B','B','A','A'], ['ONE','TWO','ONE','ONE','ONE','TWO','ONE','TWO','ONE','THREE']]).T
df.columns = [['Alphabet','Words']]
print(df)   #printing dataframe.

This is our printed data:

For making a group of dataframe in pandas and counter,
You need to provide one more column which counts the grouping, let's call that column as, "COUNTER" in dataframe.

Like this:

df['COUNTER'] =1       #initially, set that counter to 1.
group_data = df.groupby(['Alphabet','Words'])['COUNTER'].sum() #sum function
print(group_data)

OUTPUT:

This is an easy way to split string by comma,

import java.util.*;

public class SeparatedByComma{
public static void main(String []args){
     String listOfStates = "Hasalak, Mahiyanganaya, Dambarawa, Colombo";
     List<String> stateList = Arrays.asList(listOfStates.split("\\,"));
     System.out.println(stateList);
 }
}

Here is another way to accomplish this in less code.

UPDATE 3: Asynchronous model class statics

Similar to option 2, this allows you to create a function directly linked to the schema, but called from the same file using the model.

model.js

 userSchema.statics.updateUser = function(user, cb) {
  UserModel.find({name : user.name}).exec(function(err, docs) {
    if (docs.length){
      cb('Name exists already', null);
    } else {
      user.save(function(err) {
        cb(err,user);
      }
    }
  });
}

Call from file

var User = require('./path/to/model');

User.updateUser(user.name, function(err, user) {
  if(err) {
    var error = new Error('Already exists!');
    error.status = 401;
    return next(error);
  }
});

How about this?

fscanf(file,"%d %d %d %d %d %d %d",&line1_1,&line1_2, &line1_3, &line2_1, &line2_2, &line3_1, &line3_2); 

In this case spaces in fscanf match multiple occurrences of any whitespace until the next token in found.

var value = fac.GetCachedValue("Auto Print Clinical Warnings")
// 0 = Start at the first character
// 1 = The length of the string to grab
if (value.ToLower().SubString(0, 1) == "y")
{
    // Do your stuff.
}

In linearLayout Instead of giving weight to Button itself , set the weight to <Space> View this won't stretch the Button.

as I am using 4 <Space> I set the android:weightSum="4" In linear layout also this is the result ::

Another way,

SELECT ACCOUNT,
      MAX(CASE WHEN Period = '2000' THEN Value ELSE NULL END) [2000],
      MAX(CASE WHEN Period = '2001' THEN Value ELSE NULL END) [2001],

• SQLFiddle Demo (both queries)

This is very good question but not as wanting as question. There is difference between 'self' and 'cls' used method though analogically they are at same place

def moon(self, moon_name):
    self.MName = moon_name

#but here cls method its use is different 

@classmethod
def moon(cls, moon_name):
    instance = cls()
    instance.MName = moon_name

Now you can see both are moon function but one can be used inside class while other function name moon can be used for any class.

For practical programming approach :

While designing circle class we use area method as cls instead of self because we don't want area to be limited to particular class of circle only .

You can find out what Git does with a file by seeing what it does when you add it to the index. The index is like a pre-commit. With the index committed, you can use git checkout to bring everything that was in the index back into the working directory. So, what does Git do when you add a symbolic link to the index?

To find out, first, make a symbolic link:

$ ln -s /path/referenced/by/symlink symlink

Git doesn't know about this file yet. git ls-files lets you inspect your index (-s prints stat-like output):

$ git ls-files -s ./symlink
[nothing]

Now, add the contents of the symbolic link to the Git object store by adding it to the index. When you add a file to the index, Git stores its contents in the Git object store.

$ git add ./symlink

So, what was added?

$ git ls-files -s ./symlink
120000 1596f9db1b9610f238b78dd168ae33faa2dec15c 0       symlink

The hash is a reference to the packed object that was created in the Git object store. You can examine this object if you look in .git/objects/15/96f9db1b9610f238b78dd168ae33faa2dec15c in the root of your repository. This is the file that Git stores in the repository, that you can later check out. If you examine this file, you'll see it is very small. It does not store the contents of the linked file. To confirm this, print the contents of the packed repository object with git cat-file:

$ git cat-file -p 1596f9db1b9610f238b78dd168ae33faa2dec15c
/path/referenced/by/symlink

(Note 120000 is the mode listed in ls-files output. It would be something like 100644 for a regular file.)

But what does Git do with this object when you check it out from the repository and into your filesystem? It depends on the core.symlinks config. From man git-config:

core.symlinks

If false, symbolic links are checked out as small plain files that contain the link text.

So, with a symbolic link in the repository, upon checkout you either get a text file with a reference to a full filesystem path, or a proper symbolic link, depending on the value of the core.symlinks config.

Either way, the data referenced by the symlink is not stored in the repository.

It's possible in ggplot and you can use scale_date for this task

 library(ggplot2)  
 Lines <- "Date            Visits
    11/1/2010   696537
    11/2/2010   718748
    11/3/2010   799355
    11/4/2010   805800
    11/5/2010   701262

    11/7/2010   690068
    11/8/2010   756947
    11/9/2010   718757
    11/10/2010  701768
    11/11/2010  820113
    11/12/2010  645259"
    dm <- read.table(textConnection(Lines), header = TRUE)
    dm <- mutate(dm, Date = as.Date(dm$Date, "%m/%d/%Y"))
    ggplot(data = dm, aes(Date, Visits)) + 
    geom_line() + 
    scale_x_date(format = "%b %d", major =  "1 day")

When I added module: 'jsr305' as an additional exclude statement, it all worked out fine for me.

 androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
exclude module: 'jsr305'

})

With PostgreSQL 9.1 this can be achieved using a writeable CTE (common table expression):

WITH new_values (id, field1, field2) as (
  values 
     (1, 'A', 'X'),
     (2, 'B', 'Y'),
     (3, 'C', 'Z')

),
upsert as
( 
    update mytable m 
        set field1 = nv.field1,
            field2 = nv.field2
    FROM new_values nv
    WHERE m.id = nv.id
    RETURNING m.*
)
INSERT INTO mytable (id, field1, field2)
SELECT id, field1, field2
FROM new_values
WHERE NOT EXISTS (SELECT 1 
                  FROM upsert up 
                  WHERE up.id = new_values.id)

See these blog entries:

• Upserting via Writeable CTE
• WAITING FOR 9.1 – WRITABLE CTE
• WHY IS UPSERT SO COMPLICATED?

Note that this solution does not prevent a unique key violation but it is not vulnerable to lost updates.

Since FFT is symmetric over it's centre, half the values are just enough.

import numpy as np
import matplotlib.pyplot as plt

fs = 30.0
t = np.arange(0,10,1/fs)
x = np.cos(2*np.pi*10*t)

xF = np.fft.fft(x)
N = len(xF)
xF = xF[0:N/2]
fr = np.linspace(0,fs/2,N/2)

plt.ion()
plt.plot(fr,abs(xF)**2)

I think git fetch is what your looking for.

It will pull the changes and objects without committing them to your local repo's index.

They can be merged later with git merge.

Man Page

Edit: Further Explination

Straight from the Git- SVN Crash Course link

Now, how do you get any new changes from a remote repository? You fetch them:

git fetch http://host.xz/path/to/repo.git/ 

At this point they are in your repository and you can examine them using:

git log origin 

You can also diff the changes. You can also use git log HEAD..origin to see just the changes you don't have in your branch. Then if would like to merge them - just do:

git merge origin

Note that if you don't specify a branch to fetch, it will conveniently default to the tracking remote.

Reading the man page is honestly going to give you the best understanding of options and how to use it.

I'm just trying to do this by examples and memory, I don't currently have a box to test out on. You should look at:

git log -p //log with diff

A fetch can be undone with git reset --hard (link) , however all uncommitted changes in your tree will be lost as well as the changes you've fetched.

To create a property class please select your package where you wants to create your property file.

Right click on the package and select other. Now select File and type your file name with (.properties) suffix. For example: db.properties. Than click finish. Now you can write your code inside this property file.

From local to server:

scp file1.txt file2.sh [email protected]:~/pathtoupload

From server to local:

scp -T [email protected]:"file1.txt file2.txt" "~/yourpathtocopy"

My error occurred because, somehow, there was an obj folder created inside my controllers folder. Just do a search in your application for a line inside your Assemblyinfo.cs. There may be a duplicate somewhere.

this issue is because of low storage space availability of a particular drive(c:\ or d:\ etc.,), release some memory then it will work.

Thanks Saikumar.P

It's not only about public or private methods or functions, it is about implementation details. Private functions are just one aspect of implementation details.

Unit-testing, after all, is a white box testing approach. For example, whoever uses coverage analysis to identify parts of the code that have been neglected in testing so far, goes into the implementation details.

A) Yes, you should be testing implementation details:

Think of a sort function which for performance reasons uses a private implementation of BubbleSort if there are up to 10 elements, and a private implementation of a different sort approach (say, heapsort) if there are more than 10 elements. The public API is that of a sort function. Your test suite, however, better makes use of the knowledge that there are actually two sort algorithms used.

In this example, surely, you could perform the tests on the public API. This would, however, require to have a number of test cases that execute the sort function with more than 10 elements, such that the heapsort algorithm is sufficiently well tested. The existence of such test cases alone is an indication that the test suite is connected to the implementation details of the function.

If the implementation details of the sort function change, maybe in the way that the limit between the two sorting algorithms is shifted or that heapsort is replaced by mergesort or whatever: The existing tests will continue to work. Their value nevertheless is then questionable, and they likely need to be reworked to better test the changed sort function. In other words, there will be a maintenance effort despite the fact that tests were on the public API.

B) How to test implementation details

One reason why many people argue one should not test private functions or implementation details is, that the implementation details are more likely to change. This higher likelyness of change at least is one of the reasons for hiding implementation details behind interfaces.

Now, assume that the implementation behind the interface contains larger private parts for which individual tests on the internal interface might be an option. Some people argue, these parts should not be tested when private, they should be turned into something public. Once public, unit-testing that code would be OK.

This is interesting: While the interface was internal, it was likely to change, being an implementation detail. Taking the same interface, making it public does some magic transformation, namely turning it into an interface that is less likely to change. Obviously there is some flaw in this argumentation.

But, there is nevertheless some truth behind this: When testing implementation details, in particular using internal interfaces, one should strive to use interfaces that are likely to remain stable. Whether some interface is likely to be stable is, however, not simply decidable based on whether it is public or private. In the projects from world I have been working in for some time, public interfaces also often enough change, and many private interfaces have remained untouched for ages.

Still, it is a good rule of thumb to use the "front door first" (see http://xunitpatterns.com/Principles%20of%20Test%20Automation.html). But keep in mind that it is called "front door first" and not "front door only".

C) Summary

Test also the implementation details. Prefer testing on stable interfaces (public or private). If implementation details change, also tests on the public API need to be revised. Turning something private into public does not magically change its stability.

If you want to use Angular with an unsupported TypeScript version, add this to your tsconfig.json to ignore the warning:

  "angularCompilerOptions": {
    "disableTypeScriptVersionCheck": true,
  },

Simply use Contains method. Note that it works based on the equality function Equals

bool alreadyExist = list.Contains(item);

This could be the easiest in my opinion:

SELECT * FROM `table` WHERE `timestamp` like concat(CURDATE(),'%');

You can create a class for the anchor elements that you would like to display as buttons.

Eg:

Using an image :

.button {
   display:block;
   background: url('image');
   width: same as image
   height: same as image
}

or using a pure CSS approach:

.button {
    background:#E3E3E3;
    border: 1px solid #BBBBBB;
    border-radius: 3px 3px 3px 3px;
}

Always remember to hide the text with something like:

text-indent: -9999em;

An excellent gallery of pure CSS buttons is here and you can even use the css3 button generator

Plenty of styles and choices are here

good luck

This warning comes because your dataframe x is a copy of a slice. This is not easy to know why, but it has something to do with how you have come to the current state of it.

You can either create a proper dataframe out of x by doing

x = x.copy()

This will remove the warning, but it is not the proper way

You should be using the DataFrame.loc method, as the warning suggests, like this:

x.loc[:,'Mass32s'] = pandas.rolling_mean(x.Mass32, 5).shift(-2)

You can just replace like this,

 var someString = "23/03/2012";
 someString.replace(/\//g, "-");

It works for me..

There is a great library used to manipulate dates: Delorean

import datetime
from delorean import Delorean
now = datetime.datetime.now()
d = Delorean(now, timezone='US/Pacific')

>>> now    
datetime.datetime(2015, 3, 26, 19, 46, 40, 525703)

>>> d.truncate('second')
Delorean(datetime=2015-03-26 19:46:40-07:00, timezone='US/Pacific')

>>> d.truncate('minute')
Delorean(datetime=2015-03-26 19:46:00-07:00, timezone='US/Pacific')

>>> d.truncate('hour')
Delorean(datetime=2015-03-26 19:00:00-07:00, timezone='US/Pacific')

>>> d.truncate('day')
Delorean(datetime=2015-03-26 00:00:00-07:00, timezone='US/Pacific')

>>> d.truncate('month')
Delorean(datetime=2015-03-01 00:00:00-07:00, timezone='US/Pacific')

>>> d.truncate('year')
Delorean(datetime=2015-01-01 00:00:00-07:00, timezone='US/Pacific')

and if you want to get datetime value back:

>>> d.truncate('year').datetime
datetime.datetime(2015, 1, 1, 0, 0, tzinfo=<DstTzInfo 'US/Pacific' PDT-1 day, 17:00:00 DST>)

Why does this error occur?

Because you tried to access an element in a collection, using a numeric index that exceeds the collection's boundaries.

The first element in a collection is generally located at index 0. The last element is at index n-1, where n is the Size of the collection (the number of elements it contains). If you attempt to use a negative number as an index, or a number that is larger than Size-1, you're going to get an error.

How indexing arrays works

When you declare an array like this:

var array = new int[6]

The first and last elements in the array are

var firstElement = array[0];
var lastElement = array[5];

So when you write:

var element = array[5];

you are retrieving the sixth element in the array, not the fifth one.

Typically, you would loop over an array like this:

for (int index = 0; index < array.Length; index++)
{
    Console.WriteLine(array[index]);
}

This works, because the loop starts at zero, and ends at Length-1 because index is no longer less than Length.

This, however, will throw an exception:

for (int index = 0; index <= array.Length; index++)
{
    Console.WriteLine(array[index]);
}

Notice the <= there? index will now be out of range in the last loop iteration, because the loop thinks that Length is a valid index, but it is not.

How other collections work

Lists work the same way, except that you generally use Count instead of Length. They still start at zero, and end at Count - 1.

for (int index = 0; i < list.Count; index++)
{
    Console.WriteLine(list[index]);
} 

However, you can also iterate through a list using foreach, avoiding the whole problem of indexing entirely:

foreach (var element in list)
{
    Console.WriteLine(element.ToString());
}

You cannot index an element that hasn't been added to a collection yet.

var list = new List<string>();
list.Add("Zero");
list.Add("One");
list.Add("Two");
Console.WriteLine(list[3]);  // Throws exception.

Putty doesn't use openssh key files - there is a utility in putty suite to convert them.

Yes, the 3rd template parameter on map specifies the comparator, which is a binary predicate. Example:

struct ByLength : public std::binary_function<string, string, bool>
{
    bool operator()(const string& lhs, const string& rhs) const
    {
        return lhs.length() < rhs.length();
    }
};

int main()
{
    typedef map<string, string, ByLength> lenmap;
    lenmap mymap;

    mymap["one"] = "one";
    mymap["a"] = "a";
    mymap["fewbahr"] = "foobar";

    for( lenmap::const_iterator it = mymap.begin(), end = mymap.end(); it != end; ++it )
        cout << it->first << "\n";
}

If you started tomcat through eclipse, It can be solved in different ways too.

Method 1:

1. Right click on server --> Properties
2. click on Switch location and apply.

Method2:

1. Double click in the server in eclipse.
2. Change Server location to Use tomcat installation(takes control of tomcat installation).

One thing to think about is: Do you have your WCF completely uncoupled from the WindowsService (WS)? A WS is painful because you don't have a lot of control or visibility to them. I try to mitigate this by having all of my non-WS stuff in their own classes so they can be tested independently of the host WS. Using this approach might help you eliminate anything that is happening with the WS runtime vs. your service in particular.

John is likely correct that it is a .config file problem. WCF will always look for the execution context .config. So if you are hosting your WCF in different execution contexts (that is, test with a console application, and deploy with a WS), you need to make sure you have WCF configuration data moved over to the proper .config file. But the underlying issue to me is that you don't know what the problem is because the WS goo gets in the way. If you haven't refactored to that yet so that you can run your service in any context (that is, unit test or console), then I'd sugget doing so. If you spun your service up in a unit test, it would likely fail the same way that you are seeing with the WS which is much easier to debug rather than attempting to do so with the yucky WS plumbing.

If you are storing keys/values as strings, then this will work:

HashMap<String, String> newMap = new HashMap<String, String>();
newMap.put("my_code", "shhh_secret");
String value = newMap.get("my_code");

The question is what gets populated in the HashMap (key & value)

Use cell magic and this project on github by Phillip Cloud:

Load it by putting this at the top of your notebook or put it in your config file if you always want to load it by default:

%install_ext https://raw.github.com/cpcloud/ipython-autotime/master/autotime.py
%load_ext autotime

If loaded, every output of subsequent cell execution will include the time in min and sec it took to execute it.

You can try it:

ImageIcon imageIcon = new ImageIcon(new ImageIcon("icon.png").getImage().getScaledInstance(20, 20, Image.SCALE_DEFAULT));
label.setIcon(imageIcon);

Or in one line:

label.setIcon(new ImageIcon(new ImageIcon("icon.png").getImage().getScaledInstance(20, 20, Image.SCALE_DEFAULT)));

The execution time is much more faster than File and ImageIO.

I recommend you to compare the two solutions in a loop.

You can do this using CliWrap in one line:

var stdout = new Cli("cmd")
         .Execute("copy /b Image1.jpg + Archive.rar Image2.jpg")
         .StandardOutput;

If X and beta do not have the same shape as the second term in the rhs of your last line (i.e. nsample), then you will get this type of error. To add an array to a tuple of arrays, they all must be the same shape.

I would recommend looking at the numpy broadcasting rules.

You probably need a clear fix.

Try this:

What methods of ‘clearfix’ can I use?

<html>
<script>
var simpleText = "hello_world";
var finalSplitText = simpleText.split("_");
var splitText = finalSplitText[0];

window.onload = function() {
       //when the document is finished loading, replace everything
       //between the <a ...> </a> tags with the value of splitText
   document.getElementById("myLink").innerHTML=splitText;
} 

</script>

<body>
<a id="myLink" href = test.html></a>
</body>
</html>

You could do it with jQuery.

$('.myClass').click(function() {
  alert('hohoho');
});

Your methods don't refer to an object (that is, self), so you should use the @staticmethod decorator:

class MathsOperations:
    @staticmethod
    def testAddition (x, y):
        return x + y

    @staticmethod
    def testMultiplication (a, b):
        return a * b

This one works fine for me :

theme.applyStyle(R.style.AppTheme, true)

Usage:

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    //The call goes right after super.onCreate() and before setContentView()
    theme.applyStyle(R.style.AppTheme, true)
    setContentView(layoutId)
    onViewCreated(savedInstanceState)
}

I had faced similar issue. I set cafile using the command:

npm config set cafile PATH_TO_CERTIFICATE

I was able to resolve this by deleting the certificate file settings, and setting strict-ssl = false.

$newstr = preg_replace('/[^a-zA-Z0-9\']/', '_', "There wouldn't be any");
$newstr = str_replace("'", '', $newstr);

I put them on two separate lines to make the code a little more clear.

Note: If you're looking for Unicode support, see Filip's answer below. It will match all characters that register as letters in addition to A-z.

Maybe it is time to start revising this answer? Personally I would vote for setActive() and unsetActive() (alternatives can be setUnActive(), notActive(), disable(), etc. depending on context) since "setActive" implies you activate it at all times, which you don't. It's kind of counter intuitive to say "setActive" but actually remove the active state.

Another problem is, you can can not listen to specifically a SetActive event in a CQRS way, you would need to listen to a 'setActiveEvent' and determine inside that listener wether is was actually set active or not. Or of course determine which event to call when calling setActive() but that then goes against the Separation of Concerns principle.

A good read on this is the FlagArgument article by Martin Fowler: http://martinfowler.com/bliki/FlagArgument.html

However, I come from a PHP background and see this trend being adopted more and more. Not sure how much this lives with Java development.

Instead of a list of dictionaries as in ShikharDua's answer, we can also represent our table as a dictionary of lists, where each list stores one column in row-order, given we know our columns beforehand. At the end we construct our DataFrame once.

For c columns and n rows, this uses 1 dictionary and c lists, versus 1 list and n dictionaries. The list of dictionaries method has each dictionary storing all keys and requires creating a new dictionary for every row. Here we only append to lists, which is constant time and theoretically very fast.

# current data
data = {"Animal":["cow", "horse"], "Color":["blue", "red"]}

# adding a new row (be careful to ensure every column gets another value)
data["Animal"].append("mouse")
data["Color"].append("black")

# at the end, construct our DataFrame
df = pd.DataFrame(data)
#   Animal  Color
# 0    cow   blue
# 1  horse    red
# 2  mouse  black

Steps (These apply for Linux. For other OS, visit here) -

1. Copy the apk file to platform-tools in android-sdk linux folder.
2. Open Terminal and navigate to platform-tools folder in android-sdk.
3. Then Execute this command -

   ./adb install FileName.apk

4. If the operation is successful (the result is displayed on the screen), then you will find your file in the launcher of your emulator.

It is possible to query this information from WMI. The following command will output a table with a row for every user along with the SID for each user.

wmic useraccount get name,sid

You can also export this information to CSV:

wmic useraccount get name,sid /format:csv > output.csv

I have used this on Vista and 7. For more information see WMIC - Take Command-line Control over WMI.

Doing it as a stored procedure does have lot of advantages. You can get the sequence that is inserted into the table using syntax insert into table_name values returning.

Like:

declare
some_seq_val  number;
lv_seq        number;
begin
some_seq_val := your_seq.nextval;
insert into your_tab (col1, col2, col3) 
values (some_seq_val, val2, val3) returning some_seq_val into lv_seq;

dbms_output.put_line('The inserted sequence is: '||to_char(lv_seq));
end;
/

Or just return some_seq_val. In case you are not making use of SEQUENCE, and arriving the sequence on some calculation, you can make use of returning into effectively.

I would suggest a slight change in your logic. It may or may not work, depending on what you need to accomplish.

handle_event() can still do the "boring default code" but instead of being virtual, at the point where you want it to do the "new exciting code" have the base class call an abstract method (i.e. must-be-overridden) method that will be supplied by your descendant class.

EDIT: And if you later decide that some of your descendant classes do not need to provide "new exciting code" then you can change the abstract to virtual and supply an empty base class implementation of that "inserted" functionality.

This is how I am doing this in swift.

extension String {
    func encodeURIComponent() -> String {
        return self.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())!
    }

    func decodeURIComponent() -> String {
        return self.componentsSeparatedByString("+").joinWithSeparator(" ").stringByRemovingPercentEncoding!
    }
}

To augment T.J.'s answer, exceeding the min/max values generates an Invalid Date.

let maxDate = new Date(8640000000000000);_x000D_
let minDate = new Date(-8640000000000000);_x000D_
_x000D_
console.log(new Date(maxDate.getTime()).toString());_x000D_
console.log(new Date(maxDate.getTime() - 1).toString());_x000D_
console.log(new Date(maxDate.getTime() + 1).toString()); // Invalid Date_x000D_
_x000D_
console.log(new Date(minDate.getTime()).toString());_x000D_
console.log(new Date(minDate.getTime() + 1).toString());_x000D_
console.log(new Date(minDate.getTime() - 1).toString()); // Invalid Date

Well you can have each form go to to a different page. (which is preferable)

Or have a different value for the a certain input and base posts on that:

switch($_POST['submit']) {
    case 'login': 
    //...
    break;
    case 'register':
    //...
    break;
}

You can also take a look at PDFMiner (or for older versions of Python see PDFMiner and PDFMiner).

A particular feature of interest in PDFMiner is that you can control how it regroups text parts when extracting them. You do this by specifying the space between lines, words, characters, etc. So, maybe by tweaking this you can achieve what you want (that depends of the variability of your documents). PDFMiner can also give you the location of the text in the page, it can extract data by Object ID and other stuff. So dig in PDFMiner and be creative!

But your problem is really not an easy one to solve because, in a PDF, the text is not continuous, but made from a lot of small groups of characters positioned absolutely in the page. The focus of PDF is to keep the layout intact. It's not content oriented but presentation oriented.

Kevin's answer works but It makes it hard to play with the data using that solution.

Best solution is don't start startActivityForResult() on activity level.

in your case don't call getActivity().startActivityForResult(i, 1);

Instead, just use startActivityForResult() and it will work perfectly fine! :)

TL;DR You are still always able to autoplay muted videos

Also, if you're want to autoplay videos on iOS add playsInline attribute, because by default iOS tries to fullscreen videos

Try

 a{
    line-height: 0; 
    font-size: 0;
    color: transparent; 
 }

The color: transparent; covers an issue with Webkit browsers still displaying 1px of the text.

I had the same problem and I created a new listener for it and used in my fragments.

1 - Your activity should have a listener interface and a list of listeners in it

2 - You should implement methods for adding and removing the listeners

3 - You should override the onBackPressed method to check that any of the listeners use the back press or not

public class MainActivity ... {

    /**
     * Back press listener list. Used for notifying fragments when onBackPressed called
     */
    private Stack<BackPressListener> backPressListeners = new Stack<BackPressListener>();


    ...

    /**
     * Adding new listener to back press listener stack
     * @param backPressListener
     */
    public void addBackPressListener(BackPressListener backPressListener) {
        backPressListeners.add(backPressListener);
    }

    /**
     * Removing the listener from back press listener stack
     * @param backPressListener
     */
    public void removeBackPressListener(BackPressListener backPressListener) {
        backPressListeners.remove(backPressListener);
    }


    // Overriding onBackPressed to check that is there any listener using this back press
    @Override
    public void onBackPressed() {

        // checks if is there any back press listeners use this press
        for(BackPressListener backPressListener : backPressListeners) {
            if(backPressListener.onBackPressed()) return;
        }

        // if not returns in the loop, calls super onBackPressed
        super.onBackPressed();
    }

}

4 - Your fragment must implement the interface for back press

5 - You need to add the fragment as a listener for back press

6 - You should return true from onBackPressed if the fragment uses this back press

7 - IMPORTANT - You must remove the fragment from the list onDestroy

public class MyFragment extends Fragment implements MainActivity.BackPressListener {


    ...

    @Override
    public void onAttach(Activity activity) {
        super.onCreate(savedInstanceState);

        // adding the fragment to listener list
        ((MainActivity) activity).addBackPressListener(this);
    }

    ...

    @Override
    public void onDestroy() {
        super.onDestroy();

        // removing the fragment from the listener list
        ((MainActivity) getActivity()).removeBackPressListener(this);
    }

    ...

    @Override
    public boolean onBackPressed() {

        // you should check that if this fragment is the currently used fragment or not
        // if this fragment is not used at the moment you should return false
        if(!isThisFragmentVisibleAtTheMoment) return false;

        if (isThisFragmentUsingBackPress) {
            // do what you need to do
            return true;
        }
        return false;
    }
}

There is a Stack used instead of the ArrayList to be able to start from the latest fragment. There may be a problem also while adding fragments to the back stack. So you need to check that the fragment is visible or not while using back press. Otherwise one of the fragments will use the event and latest fragment will not be closed on back press.

I hope this solves the problem for everyone.

Get the EOF position of the file:

def get_eof_position(file_handle):
    original_position = file_handle.tell()
    eof_position = file_handle.seek(0, 2)
    file_handle.seek(original_position)
    return eof_position

and compare it with the current position: get_eof_position == file_handle.tell().

'request.user' has the logged in user.
'request.user.username' will return username of logged in user.

This was made better in python3 and documented in the stdlib documentation

The urllib.request.Request class gained a method=... parameter in python3.

Some sample usage:

req = urllib.request.Request('https://example.com/', data=b'DATA!', method='PUT')
urllib.request.urlopen(req)

You can try sudo a2enmod rewrite if you use it in your config.

You can also try replace afxres.h with WinResrc.h

The Html.Hidden creates a hidden input but you have to specify the name and all the attributes you want to give that field and value. The Html.HiddenFor creates a hidden input for the object that you pass to it, they look like this:

Html.Hidden("yourProperty",model.yourProperty);

Html.HiddenFor(m => m.yourProperty)

In this case the output is the same!

make clean removes any intermediate or output files from your source / build tree. However, it only affects the source / build tree; it does not touch the rest of the filesystem and so will not remove previously installed software.

If you're lucky, running make uninstall will work. It's up to the library's authors to provide that, however; some authors provide an uninstall target, others don't.

If you're not lucky, you'll have to manually uninstall it. Running make -n install can be helpful, since it will show the steps that the software would take to install itself but won't actually do anything. You can then manually reverse those steps.

Your conversion data is response[25] and follow the below steps.

var i = parseFloat(response[25]).toFixed(2)
console.log(i)//-6527.34

If java not installed yet. Then program written by java cannot be run to check if java is installed or not.

You can use the following approach:

SimpleDateFormat formater=new SimpleDateFormat("yyyy-MM-dd");

long d1=formater.parse("2001-1-1").getTime();
long d2=formater.parse("2001-1-2").getTime();

System.out.println(Math.abs((d1-d2)/(1000*60*60*24)));

1. Yes. By including the function call in your input argument/s, you can call two (or more) functions at once.

For example:

def anotherfunc(inputarg1, inputarg2):
    pass
def myfunc(func = anotherfunc):
    print func

When you call myfunc, you do this:

myfunc(anotherfunc(inputarg1, inputarg2))

This will print the return value of anotherfunc.

Hope this helps!

Requiring 900 weight is not a weirdness but a intentional restriction added by FontAwesome (since they share the same unicode but just different font-weight) so that you are not hacking your way into using the 'solid' and 'light' icons, most of which are available only in the paid 'Pro' version.

From JQuery Documentation

The jqXHR objects returned by $.ajax() as of jQuery 1.5 implement the Promise interface, giving them all the properties, methods, and behavior of a Promise (see Deferred object for more information). These methods take one or more function arguments that are called when the $.ajax() request terminates. This allows you to assign multiple callbacks on a single request, and even to assign callbacks after the request may have completed. (If the request is already complete, the callback is fired immediately.) Available Promise methods of the jqXHR object include:

jqXHR.done(function( data, textStatus, jqXHR ) {});

An alternative construct to the success callback option, refer to deferred.done() for implementation details.

jqXHR.fail(function( jqXHR, textStatus, errorThrown ) {});

An alternative construct to the error callback option, the .fail() method replaces the deprecated .error() method. Refer to deferred.fail() for implementation details.

jqXHR.always(function( data|jqXHR, textStatus, jqXHR|errorThrown ) { }); 

(added in jQuery 1.6) An alternative construct to the complete callback option, the .always() method replaces the deprecated .complete() method.

In response to a successful request, the function's arguments are the same as those of .done(): data, textStatus, and the jqXHR object. For failed requests the arguments are the same as those of .fail(): the jqXHR object, textStatus, and errorThrown. Refer to deferred.always() for implementation details.

jqXHR.then(function( data, textStatus, jqXHR ) {}, function( jqXHR, textStatus, errorThrown ) {});

Incorporates the functionality of the .done() and .fail() methods, allowing (as of jQuery 1.8) the underlying Promise to be manipulated. Refer to deferred.then() for implementation details.

Deprecation Notice: The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callbacks are removed as of jQuery 3.0. You can use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

<div class="row" *ngIf="teamMembers?.length > 0">

This checks first if teamMembers has a value and if teamMembers doesn't have a value, it doesn't try to access length of undefined because the first part of the condition already fails.

Some people think that VCS systems have to be complicated. They encourage inventing terms and concepts on the field. They would probably think that numerous PhDs on the subject would be interesting. Among those are probably the ones that designed Git.

Mercurial is designed with a different mentality. Developers should not care much about VCS, and they should instead spend their time on their main function: software engineering. Mercurial allows users to use and happily abuse the system without letting them make any non-recoverable mistakes.

Any professional tool must come with a clearly designed and intuitive CLI. Mercurial users can do most of the work by issuing simple commands without any strange options. In Git double dash, crazy options are the norm. Mercurial has a substantial advantage if you are a CLI person (and to be honest, any self-respecting Software Engineer should be).

To give an example, suppose you do a commit by mistake. You forgot to edit some files. To undo you action in Mercurial you simply type:

$ hg rollback

You then get a message that the system undos your last transaction.

In Git you have to type:

$ git reset --soft HEAD^

So ok suppose you have an idea what reset is about. But in addition you have to know what "--soft" and "--hard" resets are (any intuitive guesses?). Oh and of course don't forget the '^' character in the end! (now what in Ritchie's name is that...)

Mercurial's integration with 3rd party tools like kdiff3 and meld is much better as well. Generate your patches merge your branches without much fuss. Mercurial also includes a simple http server that you activate by typing

hg serve

And let others browse your repository.

The bottom line is, Git does what Mercurial does, in a much more complicated way and with a far inferior CLI. Use Git if you want to turn the VCS of your project into a scientific-research field. Use Mercurial if you want to get the VCS job done without caring much about it, and focus on your real tasks.

// Its Working 

My feeling is 409 Conflict is the most appropriate, however, seldom seen in the wild of course:

The request could not be completed due to a conflict with the current state of the resource. This code is only allowed in situations where it is expected that the user might be able to resolve the conflict and resubmit the request. The response body SHOULD include enough information for the user to recognize the source of the conflict. Ideally, the response entity would include enough information for the user or user agent to fix the problem; however, that might not be possible and is not required.

Conflicts are most likely to occur in response to a PUT request. For example, if versioning were being used and the entity being PUT included changes to a resource which conflict with those made by an earlier (third-party) request, the server might use the 409 response to indicate that it can't complete the request. In this case, the response entity would likely contain a list of the differences between the two versions in a format defined by the response Content-Type.

Following expression returns true:

'qwe'.constructor === String

Following expression returns true:

typeof 'qwe' === 'string'

Following expression returns false (sic!):

typeof new String('qwe') === 'string'

Following expression returns true:

typeof new String('qwe').valueOf() === 'string'

Best and right way (imho):

if (someVariable.constructor === String) {
   ...
}

This can be also thought of as a simple map reduce operation if you would like to think of it from a functional programming perspective.

import os
folders = [("home",".vim"),("home","zathura")]
[reduce(lambda x,y: os.path.join(x,y), each, "") for each in folders]

reduce is builtin in Python 2.x. In Python 3.x it has been moved to itertools However the accepted the answer is better.

This has been answered below but answering if you have a list of items that needs to be joined.

if string is a variable, use the .repr method on it:

>>> s = '\tgherkin\n'

>>> s
'\tgherkin\n'

>>> print(s)
    gherkin

>>> print(s.__repr__())
'\tgherkin\n'

EDIT: This only works on API 8+ as noted by some of the comments.

This is a late answer, but you can add an onShowListener to the AlertDialog where you can then override the onClickListener of the button.

final AlertDialog dialog = new AlertDialog.Builder(context)
        .setView(v)
        .setTitle(R.string.my_title)
        .setPositiveButton(android.R.string.ok, null) //Set to null. We override the onclick
        .setNegativeButton(android.R.string.cancel, null)
        .create();

dialog.setOnShowListener(new DialogInterface.OnShowListener() {

    @Override
    public void onShow(DialogInterface dialogInterface) {

        Button button = ((AlertDialog) dialog).getButton(AlertDialog.BUTTON_POSITIVE);
        button.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
                // TODO Do something

                //Dismiss once everything is OK.
                dialog.dismiss();
            }
        });
    }
});
dialog.show();

The best solution for your browser load time would be to use a server side script to join them all together into one big .js file. Make sure to gzip/minify the final version. Single request - nice and compact.

Alternatively, you can use DOM to create a <script> tag and set the src property on it then append it to the <head>. If you need to wait for that functionality to load, you can make the rest of your javascript file be called from the load event on that script tag.

This function is based on the functionality of jQuery $.getScript()

function loadScript(src, f) {
  var head = document.getElementsByTagName("head")[0];
  var script = document.createElement("script");
  script.src = src;
  var done = false;
  script.onload = script.onreadystatechange = function() { 
    // attach to both events for cross browser finish detection:
    if ( !done && (!this.readyState ||
      this.readyState == "loaded" || this.readyState == "complete") ) {
      done = true;
      if (typeof f == 'function') f();
      // cleans up a little memory:
      script.onload = script.onreadystatechange = null;
      head.removeChild(script);
    }
  };
  head.appendChild(script);
}

// example:
loadScript('/some-other-script.js', function() { 
   alert('finished loading');
   finishSetup();
 });

This issue can also raise when you change your system password but not the same updated on your .npmrc file that exist on path C:\Users\user_name, so update your password there too.

please check on it and run npm install first and then npm start.

I know I am very late to answer this question.
But would like to add for further references to the give answers.
DesiredCapabilities are used like setting your config with key-value pair.
Below is an example related to Appium used for Automating Mobile platforms like Android and IOS.
So we generally set DesiredCapabilities for conveying our WebDriver for specific things we will be needing to run our test to narrow down the performance and to increase the accuracy.

So we set our DesiredCapabilities as:

// Created object of DesiredCapabilities class.
DesiredCapabilities capabilities = new DesiredCapabilities();

// Set android deviceName desired capability. Set your device name.
capabilities.setCapability("deviceName", "your Device Name");

// Set BROWSER_NAME desired capability.
capabilities.setCapability(CapabilityType.BROWSER_NAME, "Chrome");

// Set android VERSION desired capability. Set your mobile device's OS version.
capabilities.setCapability(CapabilityType.VERSION, "5.1");

// Set android platformName desired capability. It's Android in our case here.
capabilities.setCapability("platformName", "Android");

// Set android appPackage desired capability.

//You need to check for your appPackage Name for your app, you can use this app for that APK INFO

// Set your application's appPackage if you are using any other app. 
capabilities.setCapability("appPackage", "com.android.appPackageName");

// Set android appActivity desired capability. You can use the same app for finding appActivity of your app
capabilities.setCapability("appActivity", "com.android.calculator2.Calculator");

This DesiredCapabilities are very specific to Appium on Android Platform. For more you can refer to the official site of Selenium desiredCapabilities class

For my Android projects I've used the Base64 library from here:

http://iharder.net/base64

It's a very extensive library and so far I've had no problems with it.

using jquery $.each you can access all data and also set in table like this

<table style="width: 100%">
     <thead>
          <tr>
               <th>Id</th>
               <th>Name</th>
               <th>Category</th>
               <th>Color</th>
           </tr>
     </thead>
     <tbody id="tbody">
     </tbody>
</table>

$.each(data, function (index, item) {
     var eachrow = "<tr>"
                 + "<td>" + item[1] + "</td>"
                 + "<td>" + item[2] + "</td>"
                 + "<td>" + item[3] + "</td>"
                 + "<td>" + item[4] + "</td>"
                 + "</tr>";
     $('#tbody').append(eachrow);
});

Use the CSS property border on the <td>s following the <tr>s you do not want to have the border.

In my example I made a class noBorder that I gave to one <tr>. Then I use a simple selector tr.noBorder td to make the border go away for all the <td>s that are inside of <tr>s with the noBorder class by assigning border: 0.

Note that you do not need to provide the unit (i.e. px) if you set something to 0 as it does not matter anyway. Zero is just zero.

table, tr, td {_x000D_
  border: 3px solid red;_x000D_
}_x000D_
tr.noBorder td {_x000D_
  border: 0;_x000D_
}

<table>_x000D_
  <tr>_x000D_
    <td>A1</td>_x000D_
    <td>B1</td>_x000D_
    <td>C1</td>_x000D_
  </tr>_x000D_
  <tr class="noBorder">_x000D_
    <td>A2</td>_x000D_
    <td>B2</td>_x000D_
    <td>C2</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>A3</td>_x000D_
    <td>A3</td>_x000D_
    <td>A3</td>_x000D_
  </tr>_x000D_
</table>

Here's the output as an image:

The above answers really helped, but only delivered part of the solution. The major issue is that as soon as you remove the Default value attribute, the constraint on the column in database won't be removed. So previous default value will still stay in the database.

Here is a full solution to the problem, including removal of SQL constraints on attribute removal. I am also re-using .NET Framework's native DefaultValue attribute.

Usage

[DatabaseGenerated(DatabaseGeneratedOption.Computed)]
[DefaultValue("getutcdate()")]
public DateTime CreatedOn { get; set; }

For this to work you need to update IdentityModels.cs and Configuration.cs files

IdentityModels.cs file

Add/update this method in your ApplicationDbContext class

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
            base.OnModelCreating(modelBuilder);
            var convention = new AttributeToColumnAnnotationConvention<DefaultValueAttribute, string>("SqlDefaultValue", (p, attributes) => attributes.SingleOrDefault().Value.ToString());
            modelBuilder.Conventions.Add(convention);
}

Configuration.cs file

Update your Configuration class constructor by registering custom Sql generator, like this:

internal sealed class Configuration : DbMigrationsConfiguration<ApplicationDbContext>
{
    public Configuration()
    {
        // DefaultValue Sql Generator
        SetSqlGenerator("System.Data.SqlClient", new DefaultValueSqlServerMigrationSqlGenerator());
    }
}

Next, add custom Sql generator class (you can add it to the Configuration.cs file or a separate file)

internal class DefaultValueSqlServerMigrationSqlGenerator : SqlServerMigrationSqlGenerator
{
    private int dropConstraintCount;

    protected override void Generate(AddColumnOperation addColumnOperation)
    {
        SetAnnotatedColumn(addColumnOperation.Column, addColumnOperation.Table);
        base.Generate(addColumnOperation);
    }

    protected override void Generate(AlterColumnOperation alterColumnOperation)
    {
        SetAnnotatedColumn(alterColumnOperation.Column, alterColumnOperation.Table);
        base.Generate(alterColumnOperation);
    }

    protected override void Generate(CreateTableOperation createTableOperation)
    {
        SetAnnotatedColumns(createTableOperation.Columns, createTableOperation.Name);
        base.Generate(createTableOperation);
    }

    protected override void Generate(AlterTableOperation alterTableOperation)
    {
        SetAnnotatedColumns(alterTableOperation.Columns, alterTableOperation.Name);
        base.Generate(alterTableOperation);
    }

    private void SetAnnotatedColumn(ColumnModel column, string tableName)
    {
        if (column.Annotations.TryGetValue("SqlDefaultValue", out var values))
        {
            if (values.NewValue == null)
            {
                column.DefaultValueSql = null;
                using var writer = Writer();

                // Drop Constraint
                writer.WriteLine(GetSqlDropConstraintQuery(tableName, column.Name));
                Statement(writer);
            }
            else
            {
                column.DefaultValueSql = (string)values.NewValue;
            }
        }
    }

    private void SetAnnotatedColumns(IEnumerable<ColumnModel> columns, string tableName)
    {
        foreach (var column in columns)
        {
            SetAnnotatedColumn(column, tableName);
        }
    }

    private string GetSqlDropConstraintQuery(string tableName, string columnName)
    {
        var tableNameSplitByDot = tableName.Split('.');
        var tableSchema = tableNameSplitByDot[0];
        var tablePureName = tableNameSplitByDot[1];

        var str = $@"DECLARE @var{dropConstraintCount} nvarchar(128)
SELECT @var{dropConstraintCount} = name
FROM sys.default_constraints
WHERE parent_object_id = object_id(N'{tableSchema}.[{tablePureName}]')
AND col_name(parent_object_id, parent_column_id) = '{columnName}';
IF @var{dropConstraintCount} IS NOT NULL
EXECUTE('ALTER TABLE {tableSchema}.[{tablePureName}] DROP CONSTRAINT [' + @var{dropConstraintCount} + ']')";

        dropConstraintCount++;
        return str;
    }
}

Based on Jeff Hillman's answer:

Here's a function you can just add to your profile.ps1 or define in current PowerShell session:

# Uninstall a Windows program
function uninstall($programName)
{
    $app = Get-WmiObject -Class Win32_Product -Filter ("Name = '" + $programName + "'")
    if($app -ne $null)
    {
        $app.Uninstall()
    }
    else {
        echo ("Could not find program '" + $programName + "'")
    }
}

Let's say you wanted to uninstall Notepad++. Just type this into PowerShell:

> uninstall("notepad++")

Just be aware that Get-WmiObject can take some time, so be patient!

If you just put '/' in the href it will reload the current window.

I think I had the same problem as you. My web.xml had version 2.5 while the project had the (right-click on Project-> Properties-> Project Facets->) Dynamic Web Module 2.3.

Although I tried to change the version from 2.3 to 2.5 ECLIPSE did not permit it. Solution: I removed the check mark under the heading Dynamic Web Module, I saved and I had Update Project. Automatically re-awakening is entering the box with the correct version. I use Eclipse Kepler.

p.s.: look at the comments of Jonathan just below, very useful.

To add to Matt wilson's answer I had a bunch of code-first entity classes but no database as I hadn't taken a backup. So I did the following on my Entity Framework project:

Open Package Manager console in Visual Studio and type the following:

Enable-Migrations

Add-Migration

Give your migration a name such as 'Initial' and then create the migration. Finally type the following:

Update-Database

Update-Database -Script -SourceMigration:0

The final command will create your database tables from your entity classes (provided your entity classes are well formed).

Indeed, window.location.origin works fine in browsers following standards, but guess what. IE isn't following standards.

So because of that, this is what worked for me in IE, FireFox and Chrome:

var full = location.protocol+'//'+location.hostname+(location.port ? ':'+location.port: '');

but for possible future enhancements which could cause conflicts, I specified the "window" reference before the "location" object.

var full = window.location.protocol+'//'+window.location.hostname+(window.location.port ? ':'+window.location.port: '');

This still loops through the cartesian product of the two lists, but it does it one line:

>>> lines1 = ['soup', 'butter', 'venison']
>>> lines2 = ['prune', 'rye', 'turkey']
>>> search_strings = ['a', 'b', 'c']
>>> any(s in l for l in lines1 for s in search_strings)
True
>>> any(s in l for l in lines2 for s in search_strings)
False

This also have the advantage that any short-circuits, and so the looping stops as soon as a match is found. Also, this only finds the first occurrence of a string from search_strings in linesX. If you want to find multiple occurrences you could do something like this:

>>> lines3 = ['corn', 'butter', 'apples']
>>> [(s, l) for l in lines3 for s in search_strings if s in l]
[('c', 'corn'), ('b', 'butter'), ('a', 'apples')]

If you feel like coding something more complex, it seems the Aho-Corasick algorithm can test for the presence of multiple substrings in a given input string. (Thanks to Niklas B. for pointing that out.) I still think it would result in quadratic performance for your use-case since you'll still have to call it multiple times to search multiple lines. However, it would beat the above (cubic, on average) algorithm.

Easiest way, follow the steps :

step 1: After Archive project, right click on project and select show in finder

step 2: Right click on that project and select show as Show package contents, in that go to Products>Applications

step 3: Right click on projectname.app

step 4: Copy projectname.app into a empty folder and zip the folder(foldername.zip)

step 5: Change the zipfolder extension to .ipa(foldername.zip -> foldername.ipa)

step 6: Now you have the final .ipa file

A way to write a common subset of HTML and XHTML

In the hope of greater portability.

In HTML, <script> is magic escapes everything until </script> appears.

So you can write:

<script>x = '<br/>';

and <br/> won't be considered a tag.

This is why strings such as:

x = '</scripts>'

must be escaped like:

x = '</scri' + 'pts>'

See: Why split the <script> tag when writing it with document.write()?

But XML (and thus XHTML, which is a "subset" of XML, unlike HTML), doesn't have that magic: <br/> would be seen as a tag.

<![CDATA[ is the XHTML way to say:

don't parse any tags until the next ]]>, consider it all a string

The // is added to make the CDATA work well in HTML as well.

In HTML <![CDATA[ is not magic, so it would be run by JavaScript. So // is used to comment it out.

The XHTML also sees the //, but will observe it as an empty comment line which is not a problem:

//

That said:

• compliant browsers should recognize if the document is HTML or XHTML from the initial doctype <!DOCTYPE html> vs <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
• compliant websites could rely on compliant browsers, and coordinate doctype with a single valid script syntax

But that violates the golden rule of the Internet:

don't trust third parties, or your product will break

Solved this bug with reinstall gulp

npm uninstall gulp
npm install gulp

I've had a similar issue with this error. In my case, I was entering the incorrect password for the Keystore.

I changed the password for the Keystore to match what I was entering (I didn't want to change the password I was entering), but it still gave the same error.

keytool -storepasswd -keystore keystore.jks

Problem was that I also needed to change the Key's password within the Keystore.

When I initially created the Keystore, the Key was created with the same password as the Keystore (I accepted this default option). So I had to also change the Key's password as follows:

keytool -keypasswd  -alias my.alias -keystore keystore.jks

In simple terms,

1. static : static variables are associated with the class, rather than with any object. Every instance of the class shares a class variable, which is in one fixed location in memory

2. volatile: This keyword is applicable to both class and instance variables.

Using volatile variables reduces the risk of memory consistency errors, because any write to a volatile variable establishes a happens-before relationship with subsequent reads of that same variable. This means that changes to a volatile variable are always visible to other threads

Have a look at this article by Javin Paul to understand volatile variables in a better way.

In absence of volatile keyword, the value of variable in each thread's stack may be different. By making the variable as volatile, all threads will get same value in their working memory and memory consistency errors have been avoided.

Here the term variable can be either static (class) variable or instance (object) variable.

Regarding your query :

Anyway a static variable value is also going to be one value for all threads, then why should we go for volatile?

If I need instance variable in my application, I can't use static variable. Even in case of static variable, consistency is not guaranteed due to Thread cache as shown in the diagram.

Using volatile variables reduces the risk of memory consistency errors, because any write to a volatile variable establishes a happens-before relationship with subsequent reads of that same variable. This means that changes to a volatile variable are always visible to other threads.

What's more, it also means that when a thread reads a volatile variable, it sees not just the latest change to the volatile, but also the side effects of the code that led up the change => memory consistency errors are still possible with volatile variables. To avoid side effects, you have to use synchronized variables. But there is a better solution in java.

Using simple atomic variable access is more efficient than accessing these variables through synchronized code

Some of the classes in the java.util.concurrent package provide atomic methods that do not rely on synchronization.

Refer to this high level concurrency control article for more details.

Especially have a look at Atomic variables.

Use the hash (#) symbol to only display trailing 0's when necessary. See the tests below.

decimal num1 = 13.1534545765;
decimal num2 = 49.100145;
decimal num3 = 30.000235;

num1.ToString("0.##");       //13.15%
num2.ToString("0.##");       //49.1%
num3.ToString("0.##");       //30%

USING PURE JAVASCRIPT: I know it's late but may be for the future people it can help:

In the HTML part:

<button id="1" onClick="reply_click()"></button>
<button id="2" onClick="reply_click()"></button>
<button id="3" onClick="reply_click()"></button>

In the Javascipt Controller:

function reply_click()
{
    alert(event.srcElement.id);
}

This way we don't have to bind the 'id' of the Element at the time of calling the javascript function.

Just to add to this, I had the full IIS feature turned on for one of my machines and it seemed to cause this to happen intermittently.

I also got random complaints about needing Admin rights to bind sites after a while, I assume that somehow it was looking at the full IIS config (Which does require admin as it's not a per-user file).

If you are stuck and nothing else is helping (and you don't want to just choose another port) then check you have removed this if it is present.

Yes , deleteBy method is supported To use it you need to annotate method with @Transactional

If you do NOT use the spring-boot-starter-parent pom, then from the Spring documentation:

I usually sort the data by the field I need to do the distinct count of then use IF(A2=A1,0,1); you get then get a 1 in the top row of each group of IDs. Simple and doesn't take any time to calculate on large datasets.

You can use selectedIndex to retrieve the current selected option:

el = document.getElementById('elemId')
selectedText = el.options[el.selectedIndex].text

You can't, Print Preview is a feature of a browser, and therefore should be protected from being called by JavaScript as it would be a security risk.

That's why your example uses Active X, which bypasses the JavaScript security issues.

So instead use the print stylesheet that you already should have and show it for media=screen,print instead of media=print.

Read Alist Apart: Going to Print for a good article on the subject of print stylesheets.

In Swift 3.0

let screenSize = UIScreen.main.bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height

In older swift: Do something like this:

let screenSize: CGRect = UIScreen.mainScreen().bounds

then you can access the width and height like this:

let screenWidth = screenSize.width
let screenHeight = screenSize.height

if you want 75% of your screen's width you can go:

let screenWidth = screenSize.width * 0.75

Swift 4.0

// Screen width.
public var screenWidth: CGFloat {
    return UIScreen.main.bounds.width
}

// Screen height.
public var screenHeight: CGFloat {
    return UIScreen.main.bounds.height
}

In Swift 5.0

let screenSize: CGRect = UIScreen.main.bounds

For those who use Data Binding:

1. Add the following static method to any class

   @BindingAdapter("app:thumbTintCompat")
   public static void setThumbTint(SeekBar seekBar, @ColorInt int color) {
       seekBar.getThumb().setColorFilter(color, PorterDuff.Mode.SRC_IN);
   }
   

2. Add app:thumbTintCompat attribute to your SeekBar

   <SeekBar
          android:id="@+id/seek_bar"
          style="@style/Widget.AppCompat.SeekBar"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          app:thumbTintCompat="@{@android:color/white}"
   />
   

That's it. Now you can use app:thumbTintCompat with any SeekBar. The progress tint can be configured in the same way.

Note: this method is also compatble with pre-lollipop devices.

On OSX, you can take advantage of the UNIX-like command line - here's what I keep handy in my .bashrc to enable me to more easily restart a server that's running in background (-d) mode (note that you have to be in the Rails root directory when running this):

alias restart_rails='kill -9 `cat tmp/pids/server.pid`; rails server -d'

My initial response to the comment by @zane about how the PID file isn't removed was that it might be behavior dependent on the Rails version or OS type. However, it's also possible that the shell runs the second command (rails server -d) sooner than the kill can actually cause the previous running instance to stop.

So alternatively, kill -9 cat tmp/pids/server.pid && rails server -d might be more robust; or you can specifically run the kill, wait for the tmp/pids folder to empty out, then restart your new server.

For me this location worked: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DevDiv\vc\Servicing\11.0\RuntimeMinimum\Version

Check what version you have after you installed the package and use that as a condition in your installer. (mine is set to 11.0.50727 after installing VCred).

Don't use your raw url

Instead of:

cookieManager.setCookie(myUrl, cookieString); 

use it like this:

cookieManager.setCookie("your url host", cookieString); 

Actually there is a way to just white-list all nested parameters.

params.require(:widget).permit(:name, :description).tap do |whitelisted|
  whitelisted[:position] = params[:widget][:position]
  whitelisted[:properties] = params[:widget][:properties]
end

This method has advantage over other solutions. It allows to permit deep-nested parameters.

While other solutions like:

params.require(:person).permit(:name, :age, pets_attributes: [:id, :name, :category])

Don't.

A great search engine for special characters that I recenetly found: amp-what?

You can even search by object name, like "arrow", "chess", etc...

The property you are looking for that first td is rowspan: http://www.angelfire.com/fl5/html-tutorial/tables/tr_code.htm

<table>
<tr><td rowspan="2"></td><td colspan='4'></td></tr>
<tr><td></td><td></td><td></td><td></td></tr>
<tr><td></td><td></td><td></td><td></td><td></td></tr>
</table>

If you're using at least .NET 3.5, i would suggest to use Linq-To-DataTable instead since it's much more readable and powerful:

DataTable tblFiltered = table.AsEnumerable()
          .Where(row => row.Field<String>("Nachname") == username
                   &&   row.Field<String>("Ort") == location)
          .OrderByDescending(row => row.Field<String>("Nachname"))
          .CopyToDataTable();

Above code is just an example, actually you have many more methods available.

Remember to add using System.Linq; and for the AsEnumerable extension method a reference to the System.Data.DataSetExtensions dll (How).

        List<String> bases = new LinkedList<String>();

            overlapIndex++;
        }

        StringBuilder relativePath = new StringBuilder();
        for (int i = overlapIndex; i < bases.size(); i++) {
            relativePath.append("..").append(File.separatorChar);
        }

        for (int i = overlapIndex; i < files.size(); i++) {

This is pretty old, but I found following worth noting:

PS N:\> (measure-command {Get-WmiObject -Class Win32_LogicalDisk|select -property deviceid|%{$_.deviceid}|out-host}).totalmilliseconds
...
928.7403
PS N:\> (measure-command {gdr -psprovider 'filesystem'|%{$_.name}|out-host}).totalmilliseconds
...
169.474

Without filtering properties, on my test system, 4319.4196ms to 1777.7237ms. Unless I need a PS-Drive object returned, I'll stick with WMI.

EDIT: I think we have a winner: PS N:> (measure-command {[System.IO.DriveInfo]::getdrives()|%{$_.name}|out-host}).to??talmilliseconds 110.9819

In my case, the issue was a misconstrued list of command-line arguments. I was doing this in my deployment file:

...
args:
  - "--foo 10"
  - "--bar 100"

Instead of the correct approach:

...
args:
  - "--foo"
  - "10"
  - "--bar"
  - "100"

So you use this:

var opt = {
        autoOpen: false,
        modal: true,
        width: 550,
        height:650,
        title: 'Details'
};

var theDialog = $("#divDialog").dialog(opt);
theDialog.dialog("open");

and if you open a MVC Partial View in Dialog, you can create in index a hidden button and JQUERY click event:

$("#YourButton").click(function()
{
   theDialog.dialog("open");
   OR
   theDialog.dialog("close");
});

then inside partial view html you call button trigger click like:

$("#YouButton").trigger("click")

see ya.

select T.object_id, T.name, I.indid, I.rows 
  from Sys.tables T 
  left join Sys.sysindexes I 
    on (I.id = T.object_id and (indid =1 or indid =0 ))
 where T.type='U'

Here indid=1 means a CLUSTERED index and indid=0 is a HEAP

Open angular.json file and find budgets keyword.

It should look like:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "2mb",
          "maximumError": "5mb"
       }
    ]

As you’ve probably guessed you can increase the maximumWarning value to prevent this warning, i.e.:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "4mb", <===
          "maximumError": "5mb"
       }
    ]

What does budgets mean?

A performance budget is a group of limits to certain values that affect site performance, that may not be exceeded in the design and development of any web project.

In our case budget is the limit for bundle sizes.

Yes. Youtube API is the best resource for this.

There are 3 way to embed a video:

• IFrame embeds using <iframe> tags
• IFrame embeds using the IFrame Player API
• AS3 (and AS2*) object embeds DEPRECATED

I think you are looking for the second one of them:

IFrame embeds using the IFrame Player API

The HTML and JavaScript code below shows a simple example that inserts a YouTube player into the page element that has an id value of ytplayer. The onYouTubePlayerAPIReady() function specified here is called automatically when the IFrame Player API code has loaded. This code does not define any player parameters and also does not define other event handlers.

<div id="ytplayer"></div>

<script>
  // Load the IFrame Player API code asynchronously.
  var tag = document.createElement('script');
  tag.src = "https://www.youtube.com/player_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

  // Replace the 'ytplayer' element with an <iframe> and
  // YouTube player after the API code downloads.
  var player;
  function onYouTubePlayerAPIReady() {
    player = new YT.Player('ytplayer', {
      height: '390',
      width: '640',
      videoId: 'M7lc1UVf-VE'
    });
  }
</script>

Here are some instructions where you may take a look when starting using the API.

An embed example without using iframe is to use <object> tag:

<object width="640" height="360">
    <param name="movie" value="http://www.youtube.com/embed/yt-video-id?html5=1&amp;rel=0&amp;hl=en_US&amp;version=3"/
    <param name="allowFullScreen" value="true"/>
    <param name="allowscriptaccess" value="always"/>
    <embed width="640" height="360" src="http://www.youtube.com/embed/yt-video-id?html5=1&amp;rel=0&amp;hl=en_US&amp;version=3" class="youtube-player" type="text/html" allowscriptaccess="always" allowfullscreen="true"/>
</object>

(replace yt-video-id with your video id)

as of Jan 2017, unfortunately @Adi's answer, while it seems like it should work, does not. (Google's API key process is buggy)

you'll need to click "get a key" from this link: https://developers.google.com/maps/documentation/javascript/get-api-key

also I strongly recommend you don't ever choose "secure key" until you are ready to switch to production. I did http referrer restrictions on a key and afterwards was unable to get it working with localhost, even after disabling security for the key. I had to create a new key for it to work again.

Update August 2019

In Android Studio 3.5 Instant Run was replaced with Apply Changes. And it works in different way: APK is not modified on the fly anymore but instead runtime instrumentation is used to redefine classes on the fly (more info). So since Android Studio 3.5 instant run settings are replaced with Deployment (Settings -> Build, Execution, Deployment -> Deployment):

And yet another approach using the decorator pattern and PHPs magic getter & setters:

// A simple StdClass object    
$stdclass = new StdClass();
$stdclass->foo = 'bar';

// Decorator base class to inherit from
class Decorator {

    protected $object = NULL;

    public function __construct($object)
    {
       $this->object = $object;  
    }

    public function __get($property_name)
    {
        return $this->object->$property_name;   
    }

    public function __set($property_name, $value)
    {
        $this->object->$property_name = $value;   
    }
}

class MyClass extends Decorator {}

$myclass = new MyClass($stdclass)

// Use the decorated object in any type-hinted function/method
function test(MyClass $object) {
    echo $object->foo . '<br>';
    $object->foo = 'baz';
    echo $object->foo;   
}

test($myclass);

Suggestions:

• use consistent 3-4 space indenting and you will find these problems much easier
• use a brace style that lines up {} vertically and you will see these problems quickly
• always indent control blocks another level
• use a syntax highlighting editor, it helps, you'll thank me later

for example,

type
functionname( arguments )
{
    if (something)
    {
        do stuff
    }
    else
    {
        do other stuff
    }
    switch (value)
    {
        case 'a':
            astuff
            break;
        case 'b':
            bstuff
            //fallthrough //always comment fallthrough as intentional
        case 'c':
            break;
        default: //always consider default, and handle it explicitly
            break;
    }
    while ( the lights are on )
    {
        if ( something happened )
        {
            run around in circles
            if ( you are scared ) //yeah, much more than 3-4 levels of indent are too many!
            {
                scream and shout
            }
        }
    }
    return typevalue; //always return something, you'll thank me later
}

<a href="#" style="text-decoration:none !important; text-decoration:none;">BOOK NOW</a>

Outlook will strip out the style with !important tag leaving the regular style, thus no underline. The !important tag will over rule the web based email clients' default style, thus leaving no underline.

Assuming the second window is defined as public partial class Window2 : Window, you can do it by:

Window2 win2 = new Window2();
win2.Show();

Just adding an answer because I came to this question to see the best way to include the version from package.json in my web application.

I know this question is targetted for Node.js however, if you are using Webpack to bundle your app just a reminder the recommended way is to use the DefinePlugin to declare a global version in the config and reference that. So you could do in your webpack.config.json

const pkg = require('../../package.json');

...

plugins : [
    new webpack.DefinePlugin({
      AppVersion: JSON.stringify(pkg.version),
...

And then AppVersion is now a global that is available for you to use. Also make sure in your .eslintrc you ignore this via the globals prop

Interesting I just ran a test using LinqPad with SQL Server which should be just running Linq to SQL underneath and it generates the following SQL statement.

Records .Where(r => r.Name.Contains("lkjwer--_~[]"))

-- Region Parameters
DECLARE @p0 VarChar(1000) = '%lkjwer--~_~~~[]%'
-- EndRegion
SELECT [t0].[ID], [t0].[Name]
FROM [RECORDS] AS [t0]
WHERE [t0].[Name] LIKE @p0 ESCAPE '~'

So I haven't tested it yet but it looks like potentially the ESCAPE '~' keyword may allow for automatic escaping of a string for use within a like expression.

An example:

log4j.rootLogger=ERROR, logfile

log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.logfile.datePattern='-'dd'.log'
log4j.appender.logfile.File=log/radius-prod.log
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%-6r %d{ISO8601} %-5p %40.40c %x - %m\n

log4j.logger.foo.bar.Baz=DEBUG, myappender
log4j.additivity.foo.bar.Baz=false

log4j.appender.myappender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.myappender.datePattern='-'dd'.log'
log4j.appender.myappender.File=log/access-ext-dmz-prod.log
log4j.appender.myappender.layout=org.apache.log4j.PatternLayout
log4j.appender.myappender.layout.ConversionPattern=%-6r %d{ISO8601} %-5p %40.40c %x - %m\n

The alternative for explode in php is split.

The first parameter is the delimiter, the second parameter the maximum number splits. The parts are returned without the delimiter present (except possibly the last part). When the delimiter is None, all whitespace is matched. This is the default.

>>> "Rajasekar SP".split()
['Rajasekar', 'SP']

>>> "Rajasekar SP".split('a',2)
['R','j','sekar SP']

After a lot of tries this command worked for me:

curl -v -F filename=image.jpg -F [email protected] http://localhost:8080/api/upload

Use aapt from the SDK like

aapt dump badging yourpkg.apk

This will print the package name together with other info.

the tools is located in
<sdk_home>/build-tools/android-<api_level>
or
<sdk_home>/platform-tools
or
<sdk_home>/platforms/android-<api_level>/tools

In C++11, the using keyword when used for type alias is identical to typedef.

7.1.3.2

A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.

Bjarne Stroustrup provides a practical example:

typedef void (*PFD)(double);    // C style typedef to make `PFD` a pointer to a function returning void and accepting double
using PF = void (*)(double);    // `using`-based equivalent of the typedef above
using P = [](double)->void; // using plus suffix return type, syntax error
using P = auto(double)->void // Fixed thanks to DyP

Pre-C++11, the using keyword can bring member functions into scope. In C++11, you can now do this for constructors (another Bjarne Stroustrup example):

class Derived : public Base { 
public: 
    using Base::f;    // lift Base's f into Derived's scope -- works in C++98
    void f(char);     // provide a new f 
    void f(int);      // prefer this f to Base::f(int) 

    using Base::Base; // lift Base constructors Derived's scope -- C++11 only
    Derived(char);    // provide a new constructor 
    Derived(int);     // prefer this constructor to Base::Base(int) 
    // ...
}; 

Ben Voight provides a pretty good reason behind the rationale of not introducing a new keyword or new syntax. The standard wants to avoid breaking old code as much as possible. This is why in proposal documents you will see sections like Impact on the Standard, Design decisions, and how they might affect older code. There are situations when a proposal seems like a really good idea but might not have traction because it would be too difficult to implement, too confusing, or would contradict old code.

Here is an old paper from 2003 n1449. The rationale seems to be related to templates. Warning: there may be typos due to copying over from PDF.

First let’s consider a toy example:

template <typename T>
class MyAlloc {/*...*/};

template <typename T, class A>
class MyVector {/*...*/};

template <typename T>

struct Vec {
typedef MyVector<T, MyAlloc<T> > type;
};
Vec<int>::type p; // sample usage

The fundamental problem with this idiom, and the main motivating fact for this proposal, is that the idiom causes the template parameters to appear in non-deducible context. That is, it will not be possible to call the function foo below without explicitly specifying template arguments.

template <typename T> void foo (Vec<T>::type&);

So, the syntax is somewhat ugly. We would rather avoid the nested ::type We’d prefer something like the following:

template <typename T>
using Vec = MyVector<T, MyAlloc<T> >; //defined in section 2 below
Vec<int> p; // sample usage

Note that we specifically avoid the term “typedef template” and introduce the new syntax involving the pair “using” and “=” to help avoid confusion: we are not defining any types here, we are introducing a synonym (i.e. alias) for an abstraction of a type-id (i.e. type expression) involving template parameters. If the template parameters are used in deducible contexts in the type expression then whenever the template alias is used to form a template-id, the values of the corresponding template parameters can be deduced – more on this will follow. In any case, it is now possible to write generic functions which operate on Vec<T> in deducible context, and the syntax is improved as well. For example we could rewrite foo as:

template <typename T> void foo (Vec<T>&);

We underscore here that one of the primary reasons for proposing template aliases was so that argument deduction and the call to foo(p) will succeed.

The follow-up paper n1489 explains why using instead of using typedef:

It has been suggested to (re)use the keyword typedef — as done in the paper [4] — to introduce template aliases:

template<class T> 
    typedef std::vector<T, MyAllocator<T> > Vec;

That notation has the advantage of using a keyword already known to introduce a type alias. However, it also displays several disavantages among which the confusion of using a keyword known to introduce an alias for a type-name in a context where the alias does not designate a type, but a template; Vec is not an alias for a type, and should not be taken for a typedef-name. The name Vec is a name for the family std::vector< [bullet] , MyAllocator< [bullet] > > – where the bullet is a placeholder for a type-name. Consequently we do not propose the “typedef” syntax. On the other hand the sentence

template<class T>
    using Vec = std::vector<T, MyAllocator<T> >;

can be read/interpreted as: from now on, I’ll be using Vec<T> as a synonym for std::vector<T, MyAllocator<T> >. With that reading, the new syntax for aliasing seems reasonably logical.

I think the important distinction is made here, aliases instead of types. Another quote from the same document:

An alias-declaration is a declaration, and not a definition. An alias- declaration introduces a name into a declarative region as an alias for the type designated by the right-hand-side of the declaration. The core of this proposal concerns itself with type name aliases, but the notation can obviously be generalized to provide alternate spellings of namespace-aliasing or naming set of overloaded functions (see ? 2.3 for further discussion). [My note: That section discusses what that syntax can look like and reasons why it isn't part of the proposal.] It may be noted that the grammar production alias-declaration is acceptable anywhere a typedef declaration or a namespace-alias-definition is acceptable.

Summary, for the role of using:

• template aliases (or template typedefs, the former is preferred namewise)
• namespace aliases (i.e., namespace PO = boost::program_options and using PO = ... equivalent)
• the document says A typedef declaration can be viewed as a special case of non-template alias-declaration. It's an aesthetic change, and is considered identical in this case.
• bringing something into scope (for example, namespace std into the global scope), member functions, inheriting constructors

It cannot be used for:

int i;
using r = i; // compile-error

Instead do:

using r = decltype(i);

Naming a set of overloads.

// bring cos into scope
using std::cos;

// invalid syntax
using std::cos(double);

// not allowed, instead use Bjarne Stroustrup function pointer alias example
using test = std::cos(double);

EntityFunctions is obsolete. Consider using DbFunctions instead.

var eventsCustom = eventCustomRepository.FindAllEventsCustomByUniqueStudentReference(userDevice.UniqueStudentReference)
   .Where(x => DbFunctions.TruncateTime(x.DateTimeStart) == currentDate.Date);

You are specifically asking about how they internally work, so here you are:

No synchronization

private int counter;

public int getNextUniqueIndex() {
  return counter++; 
}

It basically reads value from memory, increments it and puts back to memory. This works in single thread but nowadays, in the era of multi-core, multi-CPU, multi-level caches it won't work correctly. First of all it introduces race condition (several threads can read the value at the same time), but also visibility problems. The value might only be stored in "local" CPU memory (some cache) and not be visible for other CPUs/cores (and thus - threads). This is why many refer to local copy of a variable in a thread. It is very unsafe. Consider this popular but broken thread-stopping code:

private boolean stopped;

public void run() {
    while(!stopped) {
        //do some work
    }
}

public void pleaseStop() {
    stopped = true;
}

Add volatile to stopped variable and it works fine - if any other thread modifies stopped variable via pleaseStop() method, you are guaranteed to see that change immediately in working thread's while(!stopped) loop. BTW this is not a good way to interrupt a thread either, see: How to stop a thread that is running forever without any use and Stopping a specific java thread.

AtomicInteger

private AtomicInteger counter = new AtomicInteger();

public int getNextUniqueIndex() {
  return counter.getAndIncrement();
}

The AtomicInteger class uses CAS (compare-and-swap) low-level CPU operations (no synchronization needed!) They allow you to modify a particular variable only if the present value is equal to something else (and is returned successfully). So when you execute getAndIncrement() it actually runs in a loop (simplified real implementation):

int current;
do {
  current = get();
} while(!compareAndSet(current, current + 1));

So basically: read; try to store incremented value; if not successful (the value is no longer equal to current), read and try again. The compareAndSet() is implemented in native code (assembly).

volatile without synchronization

private volatile int counter;

public int getNextUniqueIndex() {
  return counter++; 
}

This code is not correct. It fixes the visibility issue (volatile makes sure other threads can see change made to counter) but still has a race condition. This has been explained multiple times: pre/post-incrementation is not atomic.

The only side effect of volatile is "flushing" caches so that all other parties see the freshest version of the data. This is too strict in most situations; that is why volatile is not default.

volatile without synchronization (2)

volatile int i = 0;
void incIBy5() {
  i += 5;
}

The same problem as above, but even worse because i is not private. The race condition is still present. Why is it a problem? If, say, two threads run this code simultaneously, the output might be + 5 or + 10. However, you are guaranteed to see the change.

Multiple independent synchronized

void incIBy5() {
  int temp;
  synchronized(i) { temp = i }
  synchronized(i) { i = temp + 5 }
}

Surprise, this code is incorrect as well. In fact, it is completely wrong. First of all you are synchronizing on i, which is about to be changed (moreover, i is a primitive, so I guess you are synchronizing on a temporary Integer created via autoboxing...) Completely flawed. You could also write:

synchronized(new Object()) {
  //thread-safe, SRSLy?
}

No two threads can enter the same synchronized block with the same lock. In this case (and similarly in your code) the lock object changes upon every execution, so synchronized effectively has no effect.

Even if you have used a final variable (or this) for synchronization, the code is still incorrect. Two threads can first read i to temp synchronously (having the same value locally in temp), then the first assigns a new value to i (say, from 1 to 6) and the other one does the same thing (from 1 to 6).

The synchronization must span from reading to assigning a value. Your first synchronization has no effect (reading an int is atomic) and the second as well. In my opinion, these are the correct forms:

void synchronized incIBy5() {
  i += 5 
}

void incIBy5() {
  synchronized(this) {
    i += 5 
  }
}

void incIBy5() {
  synchronized(this) {
    int temp = i;
    i = temp + 5;
  }
}

Something that has helped me: if you have ranges of variables to convert (or just more then one), you can use sapply.

A bit nonsensical but just for example:

data(cars)
cars[, 1:2] <- sapply(cars[, 1:2], as.factor)

Say columns 3, 6-15 and 37 of you dataframe need to be converted to numeric one could:

dat[, c(3,6:15,37)] <- sapply(dat[, c(3,6:15,37)], as.numeric)

You can create a custom markup extension.

Example of usage:

enum Status
{
    [Description("Available.")]
    Available,
    [Description("Not here right now.")]
    Away,
    [Description("I don't have time right now.")]
    Busy
}

At the top of your XAML:

    xmlns:my="clr-namespace:namespace_to_enumeration_extension_class

and then...

<ComboBox 
    ItemsSource="{Binding Source={my:Enumeration {x:Type my:Status}}}" 
    DisplayMemberPath="Description" 
    SelectedValue="{Binding CurrentStatus}"  
    SelectedValuePath="Value"  /> 

And the implementation...

public class EnumerationExtension : MarkupExtension
  {
    private Type _enumType;


    public EnumerationExtension(Type enumType)
    {
      if (enumType == null)
        throw new ArgumentNullException("enumType");

      EnumType = enumType;
    }

    public Type EnumType
    {
      get { return _enumType; }
      private set
      {
        if (_enumType == value)
          return;

        var enumType = Nullable.GetUnderlyingType(value) ?? value;

        if (enumType.IsEnum == false)
          throw new ArgumentException("Type must be an Enum.");

        _enumType = value;
      }
    }

    public override object ProvideValue(IServiceProvider serviceProvider)
    {
      var enumValues = Enum.GetValues(EnumType);

      return (
        from object enumValue in enumValues
        select new EnumerationMember{
          Value = enumValue,
          Description = GetDescription(enumValue)
        }).ToArray();
    }

    private string GetDescription(object enumValue)
    {
      var descriptionAttribute = EnumType
        .GetField(enumValue.ToString())
        .GetCustomAttributes(typeof (DescriptionAttribute), false)
        .FirstOrDefault() as DescriptionAttribute;


      return descriptionAttribute != null
        ? descriptionAttribute.Description
        : enumValue.ToString();
    }

    public class EnumerationMember
    {
      public string Description { get; set; }
      public object Value { get; set; }
    }
  }

I use Debian and I can simply type exec bash to achieve this. I can't say if it will work on all other distributions.

Linq to Sql.

Sql server will cache the query plans, so there's no performance gain for sprocs.

Your linq statements, on the other hand, will be logically part of and tested with your application. Sprocs are always a bit separated and are harder to maintain and test.

If I was working on a new application from scratch right now I would just use Linq, no sprocs.

This article has an excellent vimrc script for handling tabs+spaces, and converting in between them.

These commands are provided:

Space2Tab Convert spaces to tabs, only in indents.

Tab2Space Convert tabs to spaces, only in indents.

RetabIndent Execute Space2Tab (if 'expandtab' is set), or Tab2Space (otherwise).

Each command accepts an argument that specifies the number of spaces in a tab column. By default, the 'tabstop' setting is used.

This helped me a bit more than the answers here did when I first went searching for a solution.

public static void main(String arg[]) {

    Connection connection = ConnectionManager.getConnection();

Why not just:

int plusIndex = s.indexOf("+");
if (plusIndex != -1) {
    String before = s.substring(0, plusIndex);
    // Use before
}

It's not really clear why your original version didn't work, but then you didn't say what actually happened. If you want to split not using regular expressions, I'd personally use Guava:

Iterable<String> bits = Splitter.on('+').split(s);
String firstPart = Iterables.getFirst(bits, "");

If you're going to use split (either the built-in version or Guava) you don't need to check whether it contains + first - if it doesn't there'll only be one result anyway. Obviously there's a question of efficiency, but it's simpler code:

// Calling split unconditionally
String[] parts = s.split("\\+");
s = parts[0];

Note that writing String[] parts is preferred over String parts[] - it's much more idiomatic Java code.

Google has a YouTube Android Player API that enables you to incorporate video playback functionality into your Android applications. The API itself is very easy to use and works well. For example, here is how to create a new activity to play a video using the API.

Intent intent = YouTubeStandalonePlayer.createVideoIntent(this, "<<YOUTUBE_API_KEY>>", "<<Youtube Video ID>>", 0, true, false);   
startActivity(intent);

See this for more details.

You could use advanced options to run Google tests.

To run only some unit tests you could use --gtest_filter=Test_Cases1* command line option with value that accepts the * and ? wildcards for matching with multiple tests. I think it will solve your problem.

UPD:

Well, the question was how to run specific test cases. Integration of gtest with your GUI is another thing, which I can't really comment, because you didn't provide details of your approach. However I believe the following approach might be a good start:

1. Get all testcases by running tests with --gtest_list_tests
2. Parse this data into your GUI
3. Select test cases you want ro run
4. Run test executable with option --gtest_filter

If you have a custom button with a background image.You can set the tint color of your button and override the image with following .

In assets select the button background you want to set tint color.

In the attribute inspector of the image set the value render as to "Template Image"

Now whenever you setbutton.tintColor = UIColor.red you button will be shown in red.

I've been using this answer to great effect: Get the property, as a string, from an Expression<Func<TModel,TProperty>>

I realize I already answered this question a while back. The only advantage my other answer has is that it works for static properties. I find the syntax in this answer much more useful because you don't have to create a variable of the type you want to reflect.

Since you don't call Num.__init__ , the field "n1" never gets created. Call it and then it will be there.

What you missed here is timezones.

Presumably you've five hours off UTC, so 2013-09-01T11:00:00 local and 2013-09-01T06:00:00Z are the same time.

You need to read the top of the datetime docs, which explain about timezones and "naive" and "aware" objects.

If your original naive datetime was UTC, the way to recover it is to use utcfromtimestamp instead of fromtimestamp.

On the other hand, if your original naive datetime was local, you shouldn't have subtracted a UTC timestamp from it in the first place; use datetime.fromtimestamp(0) instead.

Or, if you had an aware datetime object, you need to either use a local (aware) epoch on both sides, or explicitly convert to and from UTC.

If you have, or can upgrade to, Python 3.3 or later, you can avoid all of these problems by just using the timestamp method instead of trying to figure out how to do it yourself. And even if you don't, you may want to consider borrowing its source code.

(And if you can wait for Python 3.4, it looks like PEP 341 is likely to make it into the final release, which means all of the stuff J.F. Sebastian and I were talking about in the comments should be doable with just the stdlib, and working the same way on both Unix and Windows.)

Currently it is not possible to change the font family or size outside the editor. You can however zoom the entire user interface in and out from the View menu.

Update for our VS Code 1.0 release:

A newly introduced setting window.zoomLevel allows to persist the zoom level for good! It can have both negative and positive values to zoom in or out.

Make it lowercase first:

.m_title {text-transform: lowercase}

Then make it the first letter uppercase:

.m_title:first-letter {text-transform: uppercase}

"text-transform: capitalize" works for a word; but if you want to use for sentences this solution is perfect.

The whole code if somebody need it.

    AlarmReceiver mReceiver = new AlarmReceiver();
    context.registerReceiver(mReceiver, intentFilter);

    'YYYYYYY' : '200.0',
    'ZZZZZZZ' : '500.0',
}

Usage JavaScript code to access the key pairs

for (var key in data) 
  { if (!data.hasOwnProperty(key))
    { continue; } 
    console.log(key + ' -> ' +  data[key]);
  };

Console output should look like this

XXXXXX -> 100.0 
YYYYYYY -> 200.0 
ZZZZZZZ -> 500.0

Here is a JSFiddle to show how it works.

Here is the Java Implementation of this approach:

public static int countAllFactors(int num)
{
    TreeSet<Integer> tree_set = new TreeSet<Integer>();
    for (int i = 1; i * i <= num; i+=1)
    {
        if (num % i == 0)
        {
            tree_set.add(i);
            tree_set.add(num / i);
        }
    }
    System.out.print(tree_set);
    return tree_set.size();
}

With

with() is for eager loading. That basically means, along the main model, Laravel will preload the relationship(s) you specify. This is especially helpful if you have a collection of models and you want to load a relation for all of them. Because with eager loading you run only one additional DB query instead of one for every model in the collection.

Example:

User > hasMany > Post

$users = User::with('posts')->get();
foreach($users as $user){
    $users->posts; // posts is already loaded and no additional DB query is run
}

Has

has() is to filter the selecting model based on a relationship. So it acts very similarly to a normal WHERE condition. If you just use has('relation') that means you only want to get the models that have at least one related model in this relation.

Example:

User > hasMany > Post

$users = User::has('posts')->get();
// only users that have at least one post are contained in the collection

WhereHas

whereHas() works basically the same as has() but allows you to specify additional filters for the related model to check.

Example:

User > hasMany > Post

$users = User::whereHas('posts', function($q){
    $q->where('created_at', '>=', '2015-01-01 00:00:00');
})->get();
// only users that have posts from 2015 on forward are returned

For EF 6

using System.Data.Entity;

query.Include(x => x.Collection.Select(y => y.Property))

Make sure to add using System.Data.Entity; to get the version of Include that takes in a lambda.

For EF Core

Use the new method ThenInclude

query.Include(x => x.Collection)
     .ThenInclude(x => x.Property);

In Windows server 2012. Go to ISS -> Modules -> Remove the ServiceModel3-0.

Actually you can use x64 and Python 2.7. This is just not delivered in the standard OpenCV installer. If you build the libraries from the source (http://docs.opencv.org/trunk/doc/tutorials/introduction/windows_install/windows_install.html) or you use the opencv-python from cgohlke's comment, it works just fine.

import java.util.Scanner; //import the framework


Scanner input = new Scanner(System.in); //opens a scanner, keyboard
System.out.print("Enter a number: "); //prompt the user
int myInt = input.nextInt(); //store the input from the user

Let me know if you have any questions. Fairly self-explanatory. I commented the code so you can read it. :)

Checkout the entry on the numpy example list. Here is the entry on .loadtxt()

>>> from numpy import *
>>>
>>> data = loadtxt("myfile.txt")                       # myfile.txt contains 4 columns of numbers
>>> t,z = data[:,0], data[:,3]                         # data is 2D numpy array
>>>
>>> t,x,y,z = loadtxt("myfile.txt", unpack=True)                  # to unpack all columns
>>> t,z = loadtxt("myfile.txt", usecols = (0,3), unpack=True)     # to select just a few columns
>>> data = loadtxt("myfile.txt", skiprows = 7)                    # to skip 7 rows from top of file
>>> data = loadtxt("myfile.txt", comments = '!')                  # use '!' as comment char instead of '#'
>>> data = loadtxt("myfile.txt", delimiter=';')                   # use ';' as column separator instead of whitespace
>>> data = loadtxt("myfile.txt", dtype = int)                     # file contains integers instead of floats

If you want using it with parameter (ie. delete all subdirs under the given directory), then put this two lines into a *.bat or *.cmd file:

@echo off
for /f "delims=" %%d in ('dir %1 /s /b /ad ^| sort /r') do rd "%%d" 2>nul && echo rmdir %%d

and add script-path to your PATH environment variable. In this case you can call your batch file from any location (I suppose UNC path should work, too).

Eg.:

YourBatchFileName c:\temp

(you may use quotation marks if needed)

will remove all empty subdirs under c:\temp folder

YourBatchFileName

will remove all empty subdirs under the current directory.

You can use a TableModel.

Define a class like this:

public class MyModel extends AbstractTableModel{
    //not necessary
}

actually isCellEditable() is false by default so you may omit it. (see: http://docs.oracle.com/javase/6/docs/api/javax/swing/table/AbstractTableModel.html)

Then use the setModel() method of your JTable.

JTable myTable = new JTable();
myTable.setModel(new MyModel());

typeof is an operator to obtain a type known at compile-time (or at least a generic type parameter). The operand of typeof is always the name of a type or type parameter - never an expression with a value (e.g. a variable). See the C# language specification for more details.

GetType() is a method you call on individual objects, to get the execution-time type of the object.

Note that unless you only want exactly instances of TextBox (rather than instances of subclasses) you'd usually use:

if (myControl is TextBox)
{
    // Whatever
}

Or

TextBox tb = myControl as TextBox;
if (tb != null)
{
    // Use tb
}

It only safer as long as you don't build with -Wno-narrowing like say Google does in Chromium. If you do, then it is LESS safe. Without that flag the only unsafe cases will be fixed by C++20 though.

Note: A) Curly brackets are safer because they don't allow narrowing. B) Curly brackers are less safe because they can bypass private or deleted constructors, and call explicit marked constructors implicitly.

Those two combined means they are safer if what is inside is primitive constants, but less safe if they are objects (though fixed in C++20)
